[0033] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0034] Please refer to Figures 1-2 In the embodiments, a multi-directional adjustable seat wing is provided, which comprises a seat back frame, a direction adjusting device and a wing body.

[0035] The direction adjusting device is connected to the seat back frame, the wing body is connected to the direction adjusting device, and the direction adjusting device can move along the seat back frame in at least one direction, thereby driving the wing body to move along the seat back frame in at least one direction.

[0036] The 8-directional adjustable seat wing framework in the present application mainly consists of a seat back framework 1 and a wing adjusting mechanism 2.

[0037] Please refer to Figures 3-4 In some embodiments of the present application, the direction adjusting device comprises:

[0038] A first direction adjusting sub-device, and the first direction adjusting sub-device can reciprocate along the seat back frame in a first direction, thereby driving the wing body to reciprocate along the seat back frame in the first direction. In the embodiments, the first direction adjusting sub-device comprises a lead screw motor, a lead screw and a nut assembly.

[0039] The screw rod motor is connected with the screw rod, and the screw rod motor drives the screw rod to rotate.

[0040] The side wing adjusting mechanism 2 is composed of a side wing up-down adjusting mechanism 21, a side wing left-right adjusting mechanism 22, a side wing front-rear adjusting mechanism 23 and a side wing rotating mechanism 24.

[0041] The side wing up-down adjusting mechanism 21 needs to drive the whole side wing adjusting mechanism to move, so the application plans to realize the side wing up-down adjustment by means of electric adjustment, and the specific working principle is that the rotary motion of the screw rod motor 211 is converted into the linear motion of the nut 213 through the screw rod 212, so as to realize the whole side wing up-down adjustment.

[0042] Please refer to Figures 5-6 In some embodiments of the application, the direction adjusting device further comprises:

[0043] A second direction adjusting sub-device, and the second direction adjusting sub-device can reciprocate along the seat back frame in a second direction, so as to drive the side wing body to reciprocate along the seat back frame in the second direction. In the embodiment, the second direction adjusting sub-device comprises a fixed shaft and a first fixed sleeve.

[0044] The first fixed sleeve is connected with the nut assembly; the fixed shaft is connected with the first fixed sleeve, the outer wall of the fixed sleeve forms a first gap 223 with variable width, the first width position 2231 of the first gap accommodates and fixes the fixed shaft, and the second width position 2232 of the first gap forms a moving channel; the fixed shaft can reciprocate along the first gap in the second direction; the side wing body is connected with the fixed shaft, and the side wing body reciprocates along the first fixed sleeve in the second direction following the fixed shaft.

[0045] The side wing left-right adjusting part is relatively light in weight, and manual adjustment is relatively convenient, and the cost of manual adjustment is relatively low and the reliability is good, so the side wing left-right adjusting mechanism 22 adopts a manual adjustment mode. By manually adjusting the position of the fixed shaft 221 in the fixed sleeve 222, left-right step adjustment is realized, and the gear position in the figure is 3 levels, and in fact, the structure of the fixed sleeve can be changed according to requirements to increase the gear position.

[0046] Please refer to Figures 7-8 In some embodiments of the application, the direction adjusting device further comprises:

[0047] A third direction adjusting device, and the third direction adjusting device is reciprocable along the seat back frame in a third direction, thereby driving the side wing body to reciprocate along the seat back frame in the third direction. In the embodiment, the third direction adjusting device comprises a second fixed sleeve;

[0048] The second fixed sleeve is connected with the fixed shaft, an outer wall of the second fixed sleeve forms a second gap with a variable width, a first width position of the second gap accommodates and fixes the fixed shaft, a second width position of the second gap forms a moving channel, and the second fixed sleeve is reciprocable along the fixed shaft in a third direction. The side wing body is connected with the second fixed sleeve, and the side wing body reciprocates along the fixed shaft in the third direction following the second fixed sleeve.

[0049] The side wing front-back adjusting mechanism 23 is also manually adjusted for the same reason as the side wing left-right adjusting mode selection, and the relative position of the side wing 231 and the fixed shaft 232 is adjusted manually. The adjusting mode is the same as the front-back adjusting, and is achieved by the clamping (fixing) or passing of the fixed shaft through the different width positions in different gaps. Details are not repeated here.

[0050] In the application, to achieve the function that the fixed shaft can pass through a position with a width smaller than the diameter of the fixed shaft, a non-rigid material can be used to make the fixed sleeve. When the fixed shaft moves in the fixed sleeve, the pressure of the fixed shaft on the outside of the fixed sleeve can make the gap of the fixed sleeve widen instantaneously. When the fixed shaft moves to a position with a width smaller than the diameter of the fixed shaft, the pressure disappears, and the gap rebounds to the normal width instantaneously.

[0051] The front-back step adjusting is achieved, and the gear position is 3 in the figure. In practice, the gear position can be changed according to the requirement to increase the gear position of the side wing.

[0052] In the application, the moving modes of the side wing in the front-back direction, the left-right direction and the up-down direction can be replaced with each other, or any known mechanical structure not mentioned in the application can be used, as long as the side wing can be freely adjusted in three dimensions. All of them belong to the scope of protection of the application.

[0053] In some embodiments of the application, the direction adjusting device further comprises a knob;

[0054] The knob is connected with the fixed shaft, and the knob is rotatable along the fixed shaft in a first plane. The side wing body is connected with the knob, and the side wing body rotates along the fixed shaft in the first plane following the knob.

[0055] In some embodiments of the present application, the first direction, the second direction and the third direction are perpendicular to each other, and a second plane formed by the second direction and the third direction is parallel to the first plane.

[0056] The adjustment mode of the side wing rotation adjustment mechanism is also manual adjustment, the side wing 231 is rotated around the fixed shaft 232 by manual rotation, so as to realize stepless adjustment of the angle of the side wing.

[0057] The present application also provides a multi-directionally adjustable automobile seat, comprising the multi-directionally adjustable seat side wing of any one of the above.

[0058] Compared with the prior art, the present application provides an 8-directionally adjustable side wing framework design method, which can realize up-down, forward-backward, left-right and rotation adjustment of the side wing; when the passenger has a slim and tall body, the height of the side wing can be adjusted to a higher position, the left-right adjustment is adjusted to a position closer to the passenger, the forward-backward adjustment is adjusted to a position closer to the passenger, and the rotation side wing is adjusted to a larger angle to increase the passenger's wrapping performance; when the passenger has a plump and short body, the height of the side wing can be adjusted to a lower position, the left-right adjustment is adjusted to a position farther away from the passenger, the forward-backward adjustment is adjusted to a position farther away from the passenger, and the rotation side wing is adjusted to a smaller angle to increase the passenger's sitting space. In the present application, all adjustment modes are manual adjustment modes except for the up-down adjustment of the side wing which is in an electric mode, so that the present application has the advantages of convenient operation, simple structure, good reliability and the like, and is easy to be applied and popularized in real vehicles.
