The support device is configured such that, upon triggering of the at least one drive control module 4, the control drive assembly 32 is activated to drive the support member 31 to rotate about the first end 311.

The number of drive control modules 4 is illustratively one, two or three.

Thus, in the supporting device of the present embodiment, by triggering the driving control module 4 to control the driving assembly 32, the driving assembly 32 starts to drive the supporting member 31 to be unfolded to provide support for the first cover 1.

In some possible implementations, the supporting device of the present embodiment has at least the following three states: a default support position, a target support position, and a closed position.

State one: application scenarios that implement the default support position include, but are not limited to:

1. the user actively triggers the driving control module 4 through clicking, touch and pressing actions, the driving control module 4 inputs a starting signal to the driving component 32, the driving component 32 starts a preset time period, and the driving component 32 rotates the supporting piece 31 to a default supporting position corresponding to the preset time period.

2. The user opens the first cover 1 and the second cover 2 by rotating, so that the driving control module 4 is triggered, the driving control module 4 inputs a start signal to the driving assembly 32, the driving assembly 32 starts a preset time period, and the driving assembly 32 rotates the supporting member 31 to a default supporting position corresponding to the preset time period.

It should be noted that the default supporting position may be a fixed value, and the specific value of the default supporting position is adjusted according to the actual requirement. It will be appreciated that the default support position adjustment process includes at least: in response to an input operation, the input operation is used for setting or adjusting a numerical value of a default support position, the specific value of the default support position is adjusted according to the input operation, different default support positions can be set in different application scenes, at this time, a corresponding relation between the application scenes and the specific value of the default support position can be generated according to the input operation, and the specific value of the default support position in each application scene can be confirmed based on the corresponding relation.

It is emphasized that the above scenarios may be used alone or in combination, and the present disclosure is not limited to the above two scenarios, which are examples only and not limiting.

State two: application scenarios for achieving the target support position include, but are not limited to:

1. the user continuously clicks, touches and presses the action and continuously and actively triggers the driving control module 4, the driving control module 4 inputs continuous starting signals to the driving component 32, the driving component 32 is started, the driving support piece 31 continuously rotates, after the supporting piece 31 rotates to a target supporting position, the driving control module 4 is stopped to be triggered by stopping clicking, touching and pressing actions, the driving control module 4 stops inputting starting signals to the driving component 32, the driving component 32 stops, the supporting piece 31 stops rotating and stops at the target supporting position.

State three: application scenarios that implement the closed position include, but are not limited to:

1. the user actively triggers the driving control module 4 through clicking, touch and pressing actions, the driving control module 4 inputs a reverse start signal to the driving component 32, the driving component 32 reversely starts for a preset time period, and the driving component 32 rotates the supporting piece 31 to the closing position corresponding to the preset time period. Alternatively, the drive assembly 32 is reversed until the limit stops after the support 31 is rotated to the closed position.

2. The user closes the first cover 1 and the second cover 2 by rotating, so that the driving control module 4 is triggered, the driving control module 4 inputs a reverse start signal to the driving assembly 32, the driving assembly 32 reversely starts for a preset time period, and the driving assembly 32 rotates the supporting member 31 to the closed position corresponding to the preset time period. Alternatively, the drive assembly 32 is reversed until the limit stops after the support 31 is rotated to the closed position.

It should be noted that the above three states may be used independently or in combination, and the present disclosure is not limited to the above three states, and the above description is merely an example and not a limitation.

In some possible implementations, the driving control module 4 is in a normally open state, and the closing of the driving control module 4 requires continuous triggering by a user, and the driving control module 4 stops triggering after the user stops acting. Thus, the user can control the angle of rotation of the support 31 by triggering the driving control module 4 for a long time.

In other possible implementations, the drive control module 4 may be a two-way switch, where the drive control module 4 is turned on toward one end, the drive motor 321 is turned forward, the drive control module 4 is turned on toward the other end, and the drive motor 321 is turned back. Thus, the user can perform the unfolding or closing of the supporting member 31, or the adjustment of the specific supporting position by controlling the opening direction of the driving control module 4, controlling the rotation direction of the supporting member 31.

Referring to fig. 7, 1, and 6, in some embodiments, the driving control module 4 includes a control key 41, and the control key 41 is electrically connected to the control module 62. The user can press the action triggering control key 41 to input a control command to the control module 62, so as to control the driving assembly 32 to drive the supporting member 31 to rotate.

Illustratively, referring to fig. 1, the control key 41 is a push-trigger switch provided on the outer side 11 of the first cover 1, so that a user can trigger the support device in a horizontally placed state (e.g., the state shown in fig. 2) to be opened.

In other embodiments, the drive control module 4 includes a piezoelectric switch 42, and the piezoelectric switch 42 is electrically connected to the control module 62. The user can trigger the piezoelectric switch 42 by opening or closing the first cover 1 and the second cover 2, and input a control command to the control module 62 to control the driving assembly 32 to drive the supporting member 31 to rotate.

Illustratively, referring to fig. 6, a piezoelectric switch 42 is located between the first cover 1 and the second cover 2, and the piezoelectric switch 42 senses whether the opening or closing motion of the first cover 1 and the second cover 2 causes a pressure change to trigger.

Illustratively, the piezoelectric switch 42 includes, but is not limited to, a piezoelectric switch, a piezoelectric sensor, and the like.

In some possible implementations, when the driving assembly 32 includes the driving motor 321, the driving control module 4 controls the driving motor 321 to stop after the torque value of the driving motor 321 reaches the torque threshold, so as to prevent the driving motor 321 from rotating still after the supporting member 31 reaches the closed position, which causes structural damage.

In some possible implementations, the drive control module 4 is able to record the target support position of the support 31 during the last use and assign it to the default support position. Therefore, when the support device is used next time, the support device can be automatically adjusted to the last used target support position, and a user can directly use the support device or adjust the support device on the basis of the target support position, so that the adjustment time is saved, and the use convenience of the support device is improved.

As shown in connection with fig. 7 and 8, in some embodiments, the information acquisition module 61 includes a camera 611, a pupil locator 612, and a distance sensor 613; the camera 611 is used for collecting an image of a user, and the image at least includes facial information of the user.

The pupil locator 612 is configured to determine vertical distance information H between the pupil of the user and the horizontal plane where the first cover 1 is located according to the image; the distance sensor 613 is used to measure horizontal distance information L of the user from the first cover 1; the pupil position information includes at least vertical distance information H and horizontal distance information L.

The control module 62 determines the pupil offset angle α based on the vertical distance information H and the horizontal distance information L.

Thus, the support device of the present embodiment can measure the vertical distance information H and the horizontal distance information L of the user from the first cover 1 by using the camera 611, the pupil locator 612, and the distance sensor 613, and further calculate the pupil offset angle α.

In some possible implementations, the pupil offset angle α, α=arctan (H/L) is calculated by an arctangent function formula.

In some possible implementations, the viewing state of the user is divided into a high position, a normal position, and a low position according to the magnitude of the pupil offset angle α.

The high position is the user viewing angle is too high, and the control module 62 controls the driving assembly 32 to rotate, so that the support member 31 increases the unfolding angle and adjusts to the normal position.

The lower position is the viewing angle of the user is too low, and at this time, the control module 62 controls the driving assembly 32 to rotate, so that the support member 31 reduces the unfolding angle and adjusts to the normal position.
