Embodiment 1

[0042] like Figure 1-3 As shown, the present invention provides an anti-pinch electric headrest device, comprising a headrest mechanism 1, a backrest mechanism 2, a driving motor 3 and a control mechanism 4, the headrest mechanism 1 and the backrest mechanism 2 are rotatably connected, so The headrest mechanism 1 includes a connecting rod 12 and a linking piece 13, one end of the linking piece 13 is connected with the connecting rod 12, and the middle of the connecting rod 12 is connected with the motor push rod 31 through the first connecting piece 14. ;

[0043]The control mechanism 4 is connected to the drive motor 3, and the control mechanism 4 includes a controller 41, a motor operation control module 42 and a current sampling module 43 connected in sequence, and the current sampling module 43 is used for real-time sampling of the drive The current information of the motor 3, the controller 41 is used to control the drive motor 3 to drive the motor push rod 31 to move t...

Embodiment 2

[0065] like Figure 5 As shown, the difference between Embodiment 2 of the present invention and Embodiment 1 is that the electric headrest device further includes an alarm 44, the alarm 44 is connected to the controller 41, and the alarm 44 is used to control the Before the drive motor 3 stops running, an alarm is given.

[0066] In practical application, in the working process of the anti-pinch electric headrest device, when the retract button of the headrest is pressed, the drive motor 3 starts to retract the headrest. If the retracting working current collected in real time by the current sampling module 43 during retraction is less than the anti-pinch current, the headrest mechanism retracts smoothly. If the current sampling module 43 collects the retracting working current greater than or equal to the anti-pinch current during the retraction process, the alarm 44 alarms, and the controller 41 controls the drive motor 3 to stop running immediately through the motor opera...

Abstract

The invention discloses an anti-pinching electric headrest device, which comprises a headrest mechanism, a backrest mechanism, a driving motor and a control mechanism. The parts are connected with the motor push rod; the control mechanism is connected with the drive motor, and the control mechanism includes a sequentially connected controller, a motor operation control module and a current sampling module, and the current sampling module is used for real-time sampling of the drive The current information of the motor, the controller is used to control the drive motor to drive the motor push rod to move through the motor operation control module, so as to drive the headrest mechanism to expand or fold to the backrest mechanism. The invention also provides a control method of the anti-pinch electric headrest device, which improves the safety and sensitivity of the anti-pinch product.

Description

technical field [0001] The invention relates to the technical field of furniture manufacturing, in particular to an anti-pinch electric headrest device and a control method thereof. Background technique [0002] With the improvement of people's living standards, electric sofas, seats, bed backs and other products are becoming more and more popular, and electric sofas, seats, and bed backs are generally provided with headrest adjustment devices. The pillow pivots relative to the backrest. When a person is sitting, the back of the sofa is not only raised, but also two pillows can be raised at the waist and head, which can cushion the head and waist of the person, which will be much more comfortable; when the back is lowered to a flat level , When a person can lie down and rest, the back is flat and only the head has a pillow. [0003] With the popularity of such products, the safety requirements for products are also increasing. The main safety problem when using electric s...
