Abstract

Particular embodiments described herein provide for an electronic device, such as a notebook computer, laptop, or tablet that includes a circuit board coupled to a plurality of electronic components (which may include any type of components, elements, circuitry, etc.). One particular example implementation of a docking base comprises a base housing including at least one alignment pin disposed within the base housing. Each of the at least one alignment pin is configured to engage a corresponding alignment pin receptacle of a device housing of an electronic device. The base housing further includes an attachment mechanism coupled to the at least one first alignment pin, wherein the attachment mechanism is configured to cause the at least one first alignment pin to extend at least partially from the base housing when the device housing is within a predetermined proximity of the base housing.

First claim

What is claimed is:

1. A docking base, comprising:
a base housing including:
a first alignment pin and a second alignment pin disposed entirely within the base housing when in a retracted position, each of the first alignment pin and the second alignment pin being configured to engage a corresponding first alignment pin receptacle and second alignment pin receptacle, respectively, of a device housing of an electronic device when in an extended position;
a first electrical connector disposed entirely within the base housing when in the retracted position, the first electrical connector configured to engage a second electrical connector of the device housing when in the extended position; and
an attachment mechanism including a support member coupled to the base housing, wherein the support member is further coupled to the first alignment pin, the second alignment pin, and the first electrical connector, wherein the support member is configured to cause the first alignment pin, the second alignment pin, and the first electrical connector to extend at least partially from the base housing into the extended position substantially simultaneously when the device housing is within a predetermined proximity of the base housing; and
wherein the attachment mechanism further includes:
at least one magnetic element coupled to the support member, wherein the at least one magnetic element is configured to be magnetically attracted to the device housing to cause the first alignment pin to extend at least partially from the base housing when the device housing is within the predetermined proximity of the base housing.

2. The docking base of claim 1 , wherein the attachment mechanism is further configured to retract the first alignment pin, the second alignment pin, and the first electrical connector into the retracted position within the base housing when the device housing is not within the predetermined proximity of the base housing.

3. The docking base of claim 1 , wherein the device housing further includes at least one first magnetic element disposed proximate to at least one of the first alignment pin receptacle and the second alignment pin receptacle, the at least one first magnetic element configured to magnetically attract the at least one of the first alignment pin and the second alignment pin and move the at least one of the first alignment pin and the second alignment pin into the extended position to engage with the corresponding one of the first alignment pin receptacle and the second alignment pin receptacle when the device housing is within a predetermined proximity of the base housing.

4. The docking base of claim 3 , wherein the at least one magnetic element includes at least one second magnetic element disposed proximate to at least one of the first alignment pin and the second alignment pin, the at least one second magnetic element configured to magnetically attract the at least one of the first alignment pin and the second alignment pin to facilitate retracting of the at least one of the first alignment pin and the second alignment pin within the base housing in the retracted position when the device housing is not within the predetermined proximity of the base housing.

5. The docking base of claim 4 , wherein the base housing further comprises at least one third magnetic element in communication with the control module, wherein the control module is further configured to cause the at least one third magnetic element to magnetically attract the device housing when the current operating context is indicative of the docking operation of the device housing with the base housing.

6. The docking base of claim 1 , wherein the base housing further includes:
at least one first movable magnetic element coupled to at least one of the first alignment pin and the second alignment pin; and
a control module in communication with the at least one movable element, wherein the control module is configured to receive an input signal indicative of a current operating context of the electronic device, determine whether the at least one of the first alignment pin and the second alignment pin is to be extended or retracted from the base housing based upon the current operating context, and cause the at least one first movable magnetic element to either extend or retract the at least one of the first alignment pin and the second alignment pin based upon the determined current operating context.

7. The docking base of claim 6 , wherein the control module is further configured to cause the at least one first movable magnetic element to extend the at least one of the first alignment pin and the second alignment pin from the base housing when the current operating context is indicative of a docking operation of the device housing with the base housing.

8. The docking base of claim 6 , wherein the control module is further configured to cause the at least one first movable magnetic element to retract the at least one of the first alignment pin and the second alignment pin into the base housing when the current operating context is indicative of an undocking operation of the device housing from the base housing.

9. The docking base of claim 1 , further comprising:
at least one movable magnetic element coupled to at least one of the first alignment pin and the second alignment pin;
a control module in communication with the at least one movable element; and
a proximity sensor in communication with the control module, the proximity sensor configured to detect when the device housing is moved within a predetermined proximity to the base housing.

10. The docking base of claim 9 , wherein the control module is configured to cause the at least one movable magnetic element to extend the at least one of the first alignment pin and the second alignment pin from the base housing when the device housing is determined to be within the predetermined proximity to the base housing.

11. The docking base of claim 9 , wherein the control module is configured to cause the at least one movable magnetic element to retract the at least one of the first alignment pin and the second alignment pin into the base housing when the device housing is not determined to be within the predetermined proximity to the base housing.

12. The docking base of claim 1 , wherein the support member is coupled to the base housing by at least one spring, wherein the at least one spring is configured to apply force to bias the support member in a retracted direction.

13. The docking base of claim 12 , wherein the at least one spring is a leaf spring.

14. A system, comprising:
a device housing including a first alignment pin receptacle and a second alignment pin receptacle;
a base housing including:
a first alignment pin and a second alignment pin disposed entirely within the base housing when in a retracted position, each of the first alignment pin and the second alignment pin being configured to engage a corresponding first alignment pin receptacle and second alignment pin receptacle, respectively, of a device housing of an electronic device when in an extended position;
a first electrical connector disposed entirely within the base housing when in the retracted position, the first electrical connector configured to engage a second electrical connector of the device housing when in the extended position; and
an attachment mechanism including a support member coupled to the base housing, wherein the support member is further coupled to the first alignment pin, the second alignment pin, and the first electrical connector, wherein the support member is configured to cause the first alignment pin, the secon
