Abstract

A control method includes, in response to detecting that an external device is in a target positional relationship with an electronic device, adjusting a working parameter of a supporting assembly of the electronic device, so that the supporting assembly is in a normal working state. In the normal working state, the supporting assembly is able to support the electronic device in different postures.

First claim

What is claimed is:

1 . A control method comprising:
in response to detecting that an external device is in a target positional relationship with an electronic device, adjusting a working parameter of a supporting assembly of the electronic device by obtaining a weight parameter of the external device, so that the supporting assembly is in a normal working state; wherein in the normal working state, the supporting assembly is able to support the electronic device in different postures.

2 . The method of claim 1 , wherein obtaining the weight parameter of the external device includes at least one of:
obtaining the weight parameter of the external device in response to that the external device and the electronic device are in a first target positional relationship, the first target positional relationship representing that the external device is completely carried by a supported assembly of the electronic device, and the supported assembly being carried by the supporting assembly; or obtaining the weight parameter of the external device shared by the supported assembly of the electronic device in response to that the external device and the electronic device are in a second target positional relationship, the second target positional relationship representing that the external device is partially carried by the supported assembly.

3 . The method of claim 1 , wherein obtaining the weight parameter of the external device includes:
in response to that the external device has a communication connection with the electronic device, obtaining attribute information of the external device through the communication connection, and obtaining the weight parameter at least through the attribute information.

4 . The method of claim 1 , wherein obtaining the weight parameter of the external device includes:
in response to that the external device does not have a communication connection with the electronic device, obtaining the weight parameter of the external device using a sensor arranged at the electronic device.

5 . The method of claim 1 , wherein obtaining the weight parameter of the external device includes:
in response to that the external device has a communication connection with the electronic device, obtaining the weight parameter of the external device using a sensor arranged at the electronic device.

6 . The method of claim 1 , wherein adjusting the working parameter of the supporting assembly based on the weight parameter includes:
in response to the weight parameter being greater than a threshold, adjusting a supporting force parameter provided by the supporting assembly based on the weight parameter, the supporting force parameter including a magnitude of a supporting force.

7 . The method of claim 6 , wherein adjusting the supporting force parameter provided by the supporting assembly based on the weight parameter includes:
determining a power supply parameter for supplying power to an electromagnetic assembly of the supporting assembly based on the weight parameter, the electromagnetic assembly being configured to cooperate with the supporting assembly to generate a friction force, and the electromagnetic assembly being controlled to generate a corresponding friction force parameter based on the power supply parameter, to cooperate with a support member of the supporting assembly to provide a supporting force needed to support the supported assembly and the external device.

8 . The method of claim 6 , wherein adjusting the supporting force parameter provided by the supporting assembly based on the weight parameter includes:
determining a number of support members of the supporting assembly that are needed to provide an elastic support based on the weight parameter, so that the number of the support members are used to provide a supporting force needed to support the supported assembly and the external device.

9 . The method of claim 6 , wherein adjusting the supporting force parameter provided by the supporting assembly based on the weight parameter includes:
determining a control parameter of an auxiliary support structure based on the weight parameter, the auxiliary support structure being arranged between the supported assembly and the supporting assembly, and a supporting force provided by the auxiliary support structure being controlled based on the control parameter, so as to cooperate with the supporting assembly to provide the supporting force needed to support the supported assembly and the external device.

10 . The method of claim 1 , wherein adjusting the working parameter of the supporting assembly based on the weight parameter includes:
adjusting the working parameter of the supporting assembly and a relative positional relationship between the supporting assembly and a supported assembly of the electronic device based on the weight parameter.

11 . The method of claim 1 , further comprising:
determining a relative positional relationship between the supporting assembly and a supported assembly of the electronic device; and in response to that the supported assembly and the supporting assembly have a specific relative positional relationship, not performing the process of adjusting the working parameter of the supporting assembly of the electronic device is not performed, the specific relative positional relationship being a relationship in which the relative positional relationship between the supporting assembly and the supported assembly does not change by increasing of weight carried by the supported assembly.

12 . The method of claim 1 , further comprising:
determining a relative positional relationship between the supporting assembly and a supported assembly of the electronic device; and in response to that the relative positional relationship between the supporting assembly and the supported assembly switches from a first relative positional relationship to a second relative positional relationship or the supported assembly and the supporting assembly have the second relative positional relationship, performing the process of adjusting the working parameter of the supporting assembly of the electronic device, the first relative positional relationship being a relationship in which the relative positional relationship between the supporting assembly and the supported assembly does not change by increasing of weight carried by the supported assembly, and the second relative positional relationship being a relationship in which the relative positional relationship between the supporting assembly and the supported assembly changes due to increasing or decreasing of the weight carried by the supported assembly.

13 . The method of claim 1 , wherein adjusting the working parameter of the supporting assembly of the electronic device includes, in response to that number and/or type of the external device meets a corresponding preset condition, adjusting the supporting assembly to a maximum supporting capacity.

14 . An electronic device comprising:
