AI Technical Summary

Technical Problem

Traditional car seat headrest side wings cannot adjust automatically, causing them to easily flip over and lose their support function when there is vibration or passenger movement.

Method used

The device employs an electric headrest side wing angle adjustment mechanism, which includes a headrest support component, a sliding component, a headrest, side wings, and an electric lead screw adjustment mechanism for the headrest side wing angle. The electric mechanism drives the lead screw to rotate, which in turn causes the nut to move linearly along the lead screw, thereby adjusting the flip angle of the side wing.

Benefits of technology

During the ride, the side wings will not flip due to vibration or passenger movement, maintaining effective support.

Abstract

The utility model relates to an electric headrest side wing angle adjusting device which comprises a headrest supporting component, an angle adjusting component and an angle adjusting component. A headrest sliding member slidably disposed on the headrest support member; a headrest mounted on the headrest sliding member; the side wing is hinged to the side of the headrest sliding component; the headrest is characterized in that the headrest comprises a headrest side wing angle adjusting mechanism, the fixed side of the headrest side wing angle adjusting mechanism is installed on the headrest sliding component, and the driving side of the headrest side wing angle adjusting mechanism is in driving connection with the side wings and drives the side wings to turn over around the hinged points of the side wings and the headrest sliding component. The turnover angles of the two side wings are adjusted through the headrest side wing angle electric lead screw adjusting mechanism, and the situation that the side wings turn over backwards and lose the supporting function due to vibration and actuation of passengers is avoided.

Description

Technical Field

[0001] This utility model relates to the field of seat technology, and in particular to an electric headrest side wing angle adjustment device. Background Technology

[0002] Traditional car seat headrests have no adjustable side wings. Even if they are adjusted, it is done by manually folding with dampers. The manually adjustable side wings are all positioned by dampers. When riding, vibrations and the movements of the passenger cause the side wings to flip backward, losing their support function. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an electric headrest side wing angle adjustment device to address the aforementioned technical problems existing in the traditional car seat headrest side wing adjustment, so as to solve the various problems existing in the prior art.

[0004] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0005] An electric headrest side wing angle adjustment device includes:

[0006] Headrest support components installed on seats;

[0007] A headrest sliding component that is slidably disposed on the headrest support component;

[0008] The headrest is mounted on the headrest sliding component;

[0009] The device includes at least one side wing, which is hinged to the side of the headrest sliding component; characterized in that it further includes a headrest side wing angle adjustment mechanism, the fixed side of which is mounted on the headrest, and the driving side of which is driven to be connected to the side wing to drive the side wing to rotate around the hinge point between the side wing and the headrest.

[0010] In a preferred embodiment of this utility model, the headrest side wing angle adjustment mechanism is a headrest side wing angle electric lead screw adjustment mechanism.

[0011] In a preferred embodiment of this utility model, the headrest side wing angle electric screw adjustment mechanism includes an electric mechanism, a screw, and a nut. The electric mechanism is installed in the middle position of the headrest and is drivenly connected to the screw. The nut is screwed onto the screw and connected to the side wing.

[0012] In a preferred embodiment of this utility model, the lead screw is mounted on the headrest via a bearing seat.

[0013] Thanks to the above technical solution, the side wings will not flip backward and lose their support function due to vibration or passenger movements during the ride. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the external shape of the electric headrest side wing angle adjustment device of this utility model.

[0015] Figure 2 This is one of the schematic diagrams of the internal structure of the electric headrest side wing angle adjustment device of this utility model.

[0016] Figure 3 This is the second schematic diagram of the internal structure of the electric headrest side wing angle adjustment device of this utility model.

[0017] Figure 4 This is an exploded view of the electric headrest side wing angle adjustment device of this utility model. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] See Figures 1 to 4 The electric headrest side wing angle adjustment device shown in the figure includes: a headrest support component 100 mounted on a seat, a headrest sliding component 200 slidably disposed on the headrest support component 100, a headrest 300 mounted on the headrest sliding component 200, and a pair of side wings 400, the pair of side wings 400 being hinged to the left and right sides of the headrest sliding component.

[0020] The present invention is characterized by including a headrest side wing angle adjustment mechanism, which is a headrest side wing angle electric lead screw adjustment mechanism 500. The headrest side wing angle electric lead screw adjustment mechanism 500 includes an electric mechanism 510, a lead screw 520, and two nuts 530. The electric mechanism 510 is installed in the middle position within the headrest 300 as the fixed side of the headrest side wing angle adjustment mechanism. The electric mechanism 510 is driven by the lead screw 520, which is a double-output lead screw. One end of the lead screw 520 is mounted on the headrest 300 via a bearing seat 540. The bearing seat 540 is mounted on the headrest 300 using fasteners 550, thus providing effective dynamic support for the lead screw 520.

[0021] Two nuts 530, acting as the driving mechanism for adjusting the angle of the headrest side wings, are respectively screwed onto both ends of the lead screw 520 and connected to the two side wings 400. Thus, when the electric mechanism 510 drives the lead screw 520 to rotate, the rotation of the lead screw 520 is converted into the two nuts 530 moving linearly along the lead screw 520. The linearly moving nuts 530 drive the two side wings 400 to rotate around their hinge point with the headrest 300.

[0022] This invention uses an electric screw adjustment mechanism 500 to adjust the tilting angle of the two side wings 400, so that the side wings will not tilt backward and lose their supporting function due to vibration or passenger movements.
