[0029] The present application will be described in further detail below with reference to specific examples and in conjunction with the drawings. EMBODIMENT

[0030] As Figures 1-4As shown, the application is a kind of self-adaptive lifting armrest of car seat, which comprises a sensor 10 arranged on one side of the car door lock and capable of detecting the opening operation of the car door, a control unit 20 connected with the sensor 10, a power unit 30 controlled by the control unit 20, and an armrest body 40 driven by the power unit 30 and capable of lifting movement. Through the above structure design, when the passenger opens the car door, the sensor 10 detects the opening signal of the car door, and the power unit 30 drives the armrest body 40 to lower to the level of the seat cushion surface, which is convenient for the passenger to get on and off the car, avoids the obstruction of the armrest to the passenger getting on and off the car, and improves the convenience and comfort of the passenger getting on and off the car. When the passenger finishes getting on and off the car, the sensor 10 detects the closing signal of the car door, and the power unit 30 drives the armrest body 40 to rise to the normal use position, which provides stable support and grip for the passenger, improves the humanized design level of the car seat, and can better meet the actual use requirements of the passenger.

[0031] Specifically, the sensor 10 is a micro switch installed at the car door hinge and used for detecting the opening and closing state of the car door. Since the micro switch adopts a simple mechanical structure and can withstand millions of operation cycles without damage, it is very reliable and very suitable for applications requiring frequent operation, and can maintain stable working performance for a long time. In addition, the micro switch is small in size and light in weight, and can be conveniently installed at the car door hinge.

[0032] In the specific implementation of the embodiment, the power unit 30 is an electric motor fixed on the support frame of the side of the car seat through a mounting bracket. The electric motor drives the armrest body 40 to lift through a driving device 50. The driving device 50 comprises a driving screw 51, a shaft coupling 52, a lifting screw 53, and a screw handle 54. The shaft coupling 52 comprises a shaft sleeve 521 threadedly connected with the lifting screw 53 and a gear 522 arranged on the shaft sleeve 521. The gear 522 is engaged with the driving screw 51. The driving screw 51 and the lifting screw 53 are cross arranged. The screw handle 54 is arranged at the top end of the lifting screw 53. The driving screw 51 is installed on the output shaft of the electric motor. The screw handle is fixedly connected with the armrest body 40. In operation, the electric motor drives the driving screw 51 to rotate due to the engagement between the driving screw 51 and the gear 522. The driving screw 51 drives the gear 522 to rotate. The gear 522 drives the lifting screw 53 to move upward due to the engagement between the shaft sleeve 521 and the lifting screw 53. The armrest body 40 is driven to move upward through the screw handle 54 on the lifting screw 53. When the electric motor reverses, the screw handle 54 on the lifting screw 53 moves downward, and the armrest body 40 moves downward, thereby realizing the lifting movement of the armrest body 40.

[0033] Specifically, the handrail body 40 is oppositely provided with two slide rails 41 below, each of the slide rails 41 is slidably mounted on a sliding groove 42, the sliding groove is arranged on a support frame of the side of the car seat, and the handrail body 40 is slidably mounted on the side of the car seat through cooperation of the slide rails 41 and the sliding groove 42.

[0034] Specifically, the control unit 20 comprises a single-chip microcomputer, a signal processing circuit and a power module, the signal output end of the sensor is connected with the input end of the signal processing circuit, the output end of the signal processing circuit is connected with the input end of the single-chip microcomputer, the output end of the single-chip microcomputer is connected with the motor control end, and the power module provides electric energy for the whole control unit and the power unit.

[0035] As a further scheme of the utility model, the outer surface of the handrail body 40 is wrapped with a soft elastic material layer (not shown in the drawing), and the soft elastic material layer includes but is not limited to polyurethane (PU) foam, thermoplastic elastomer (TPE) and the like, so as to improve the comfort of passengers.

[0036] In summary, the utility model has the characteristics of reasonable structure, convenient passenger getting on and off, strong practicability and the like by the above-mentioned structure design.

[0037] The above is only a specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of claims.
