Abstract

A clamping member and a battery accommodating device are provided. The battery accommodating device includes a body and a clamping member pivotally connected to the body. The clamping member has two arm parts, two protruding parts respectively extending from one side of the two arm parts, and an elastic structure connected to the two arm parts at two ends. When the battery is placed in an accommodating slot of the body, the elastic structure is pressed by the battery, and one end of the battery is clamped between the two protruding parts and the elastic structure. When the two protruding parts are pushed by an external force, the clamping member rotates relative to the body, and the elastic structure pushes up the battery, so as to release the clamped end of the battery.

First claim

What is claimed is:

1. A clamping member, for use in a battery accommodating device having an accommodating slot for accommodating at least one battery, the clamping member comprising:
two arm parts spaced apart from each other;
two protruding parts, wherein each protruding part is formed at one end of each arm part and extends from one side of each arm part;
an elastic structure, wherein the elastic structure is connected to another end of each of the two arm parts so as to maintain the two arm parts to be spaced apart from each other, and wherein a portion of each protruding part faces toward the elastic structure, the two protruding parts and the elastic structure are configured to hold one end of the battery therebetween, and when the two arm parts move toward each other due to an external force, the elastic structure deforms elastically; and
two first pivot structures, respectively disposed on the two arm parts.

2. The clamping member according to claim 1 , wherein a portion of each of the two protruding parts, each of the two arm parts, and a portion of the elastic structure form a clamping notch with a height of 0.5 mm to 1.5 mm.

3. The clamping member according to claim 1 , wherein each of the two protruding parts comprises an inclined surface, and an included angle between the inclined surface and a horizontal plane is between 45 degrees to 55 degrees.

4. The clamping member according to claim 1 , wherein the elastic structure is an arched structure.

5. The clamping member according to claim 4 , wherein a horizontal distance between the two arm parts is a first distance, a largest vertical distance between an inner side of the elastic structure and a horizontal alignment of the two arm parts is a second distance, and the first distance is 0.25 to 4 times the second distance.

6. The clamping member according to claim 1 , wherein, for each first pivot structure and the one arm part which the first pivot structure is disposed on, a vertical distance between a center of the first pivot structure and one end of the arm part is a first vertical distance, a vertical distance between the center of the first pivot structure and another end of the arm part is a second vertical distance, and the first vertical distance is 1.5 to 4.5 times the second vertical distance.

7. A battery accommodating device for accommodating a battery, comprising:
a clamping member, comprising:
two arm parts;
two protruding parts, wherein each protruding part is formed at one end of each arm part and extends from one side of each arm part;
an elastic structure, connected to another end of each of the two arm parts, wherein a portion of each of the two protruding parts faces toward the elastic structure, the two protruding parts and the elastic structure are configured to hold one end of the battery therebetween, and when the two arm parts move toward each other due to an external force, the elastic structure deforms elastically; and
two first pivot structures, disposed respectively on the two arm parts;
a body, comprising:
an accommodating slot for accommodating the battery; and
an excess slot, in spatial communication with the accommodating slot and formed by a base part of the body receding inward, for accommodating the elastic structure;
wherein, when the elastic structure is disposed in the excess slot, the elastic structure does not protrude from the base part; and
two second pivot structures, disposed in the accommodating slot of the body and pivotally connected respectively to the two first pivot structures;
wherein the clamping member is rotatable relative to the body due to another external force.

8. The battery accommodating device according to claim 7 , further comprising two block structures connected to the body in the accommodating slot and adjacent to the two arm parts, wherein, when the clamping member rotates a predetermined angle relative to the accommodating slot due to the another external force, the two arm parts respectively lean against the two block structures, and the two block structures restrict a rotating angle of the clamping member relative to the accommodating slot.

9. The battery accommodating device according to claim 8 , wherein a horizontal distance between each one of the two arm parts and each corresponding one of the two block structures is 2 mm to 5 mm.

10. The battery accommodating device according to claim 7 , wherein a portion of each of the two protruding parts, each of the two arm parts, and a portion of the elastic structure form a clamping notch with a height of 0.5 mm to 1.5 mm.

11. The battery accommodating device according to claim 7 , wherein each of the two protruding parts comprises an inclined surface, and an included angle between the inclined surface and a horizontal plane is between 45 degrees to 55 degrees.

12. The battery accommodating device according to claim 7 , wherein the elastic structure is an arched structure.

13. The battery accommodating device according to claim 12 , wherein a horizontal distance between the two arm parts is a first distance, a largest vertical distance between an inner side of the elastic structure and a horizontal alignment of the two arm parts is a second distance, and the first distance is 0.25 to 4 times the second distance.

14. The battery accommodating device according to claim 7 , wherein, for each first pivot structure and the one arm part which the first pivot structure is connected to, a vertical distance between a center of the first pivot structure to one end of the arm part is a first vertical distance, a vertical distance between the center of the first pivot structure to another end of the arm part is a second vertical distance, and the first distance is 1.5 to 4.5 times the second vertical distance.

15. The battery accommodating device according to claim 7 , further comprising two retaining structures disposed in the body and located at one end of the accommodating slot, wherein the two retaining structures and the base part hold another end of the battery.
