Embodiment 1

[0042] Such as Figure 1-3 As shown, the present invention provides an anti-pinching electric headrest device, comprising a headrest mechanism 1, a backrest mechanism 2, a drive motor 3 and a control mechanism 4, the headrest mechanism 1 is rotatably connected to the backrest mechanism 2, and the The headrest mechanism 1 includes a connecting rod 12 and a linkage 13, one end of the linkage 13 is connected to the connecting rod 12, and the middle part of the connecting rod 12 is connected to the motor push rod 31 through the first connecting member 14 ;

[0043]The control mechanism 4 is connected with the drive motor 3, and the control mechanism 4 includes a controller 41 connected in sequence, a motor operation control module 42 and a current sampling module 43, and the current sampling module 43 is used to sample the driving motor in real time. 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 mo...

Embodiment 2

[0065] Such as Figure 5 As shown, the difference between Embodiment 2 of the present invention and Embodiment 1 is that the electric headrest device also includes an alarm 44 connected to the controller 41, and the alarm 44 is used to control The drive motor 3 gives an alarm before it stops running.

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

Abstract

The invention discloses an anti-pinch electric headrest device which comprises a headrest mechanism, a backrest mechanism, a driving motor and a control mechanism, the headrest mechanism is rotatablyconnected with the backrest mechanism, and the middle of a connecting rod is connected with a motor push rod through a first connecting piece; the control mechanism is connected with the driving motor; the control mechanism comprises a controller, a motor operation control module and a current sampling module which are connected in sequence; the current sampling module is used for sampling currentinformation of the driving motor in real time, and the controller is used for controlling the driving motor to drive the motor push rod to move through the motor operation control module so as to drive the headrest mechanism to be unfolded or folded on the backrest mechanism. The invention further provides a control method of the anti-pinch electric headrest device, and the anti-pinch safety andsensitivity of the product are improved.

Description

technical field [0001] The invention relates to the technical field of furniture manufacturing, in particular to an anti-pinching electric headrest device and a control method thereof. Background technique [0002] With the improvement of people's living standards, products such as electric sofas, seats, and bed backs are becoming more and more popular. Electric sofas, seats, and bed backs are generally equipped with headrest adjustment devices. The pillow pivots relative to the backrest. When a person is sitting, the back of the sofa not only rises, but also two pillows can be raised from the waist and head, which can cushion the head and waist of the person, which will be much more comfortable; , 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 issue when electric sofas, seats and bed backrests are in use is the a...
