[0033] like Figure 1-8As shown, an electric wing folding mechanism includes a motor mounting frame 1, a slide rail assembly 2, a drive assembly 3, a slider 4 and a wing ear mounting frame 5, wherein the drive assembly 3 and the slide rail assembly 2 are mounted on the motor mounting frame 1, the slider 4 is connected to the slide rail assembly 2, the output end of the drive assembly 3 is connected to the wing ear 6 through the slider 4, and the two wing ears are hinged on the wing ear mounting frame 5; the drive assembly 3 starts to drive the slide rail assembly 2 to move linearly through the slider 4, thereby driving the wing ear 5 to rotate open or close. The structure is symmetrically arranged, compact and reasonable, and is presented in the form of an assembly, which is more convenient and quick to assemble. Specifically, the wing ear 6 and the motor mounting frame 1 are not fixed in shape, and can be designed in different sizes and shapes as required.

[0034] Specifically, Figure 4 , 6 As shown, the drive assembly 3 includes a motor 301, a gear set 302 and a lead screw 303. The motor 301 is installed on the main frame 101 of the motor mounting frame 1 by bolts. The working end of the motor 1 is connected to one end of the lead screw 303 by the gear set 302, and the other end of the lead screw 303 is connected to the middle of the slider 4 by threading. The main frame 101 of the motor mounting frame 1 is specifically made of plastic injection molding, and the motor mounting frame 1 is connected to the corresponding position of the car seat by screws or clamps; the specific gear set uses two bevel gears to achieve the change of the rotation operation direction, and then the lead screw is connected to the slider by threading to achieve the transformation of the rotation operation to the horizontal movement operation. In addition to the existing motor driving the lead screw to rotate through the gear set to drive the slider to move, the transmission of the action can also be achieved through the transmission connection of the worm gear. When using different drive structures, other fixed connecting parts can be changed accordingly. The selection of this structure can better achieve fine-tuning to meet the folding angle requirements of different passengers. The motor is arranged vertically in the motor mounting frame 1 to save space and better adapt to the structure and installation of the seat.

[0035] Specifically, Figure 5As shown, the slide rail assembly 2 includes a slide rail base plate 201, a guide slide plate 202, a movable plate 203 and a slider positioning plate 204. The slide rail base plate 201 is mounted on the U-shaped plate 102 of the motor mounting frame 1 through a connecting frame 205. The guide slide plate 202 is connected to the inner side of the U-shaped groove of the slide rail base plate 201 by screws. The movable plate 203 is slidably connected to the guide slide plate 202. The bottom surface of the slider positioning plate 204 is connected to the movable plate 203. The bottom of the slider 4 is connected to the inside of the slider positioning plate 204. The bottom surface of the slider positioning plate 204 is welded to the movable plate 203, and the bottom of the slider 4 is connected to the groove of the slider positioning plate 204 by screws. Specifically, the guide slide plate 202 and the movable plate 203 are clamped together by a dovetail groove or a T-slot, and the movable plate 203 moves linearly along the guide slide plate 202.

[0036] like Figure 7 As shown, the side wing ear piece 6 includes an ear piece body 601 and a rotating arm 602, and the rotating arm 602 is provided with a first pin shaft hole 603 and a second pin shaft hole 604, and the first pin shaft 8 is installed in the first pin shaft hole 603, and the second pin shaft 9 is installed in the second pin shaft hole 604, and one end of the rotating arm 602 is hinged to the slider 4 through the first pin shaft 8, and the other end of the rotating arm 602 is connected to the ear piece body 601 as a whole, and the other end of the rotating arm 602 is hinged to the side wing ear piece installation frame 5 through the second pin shaft 9. Specifically, the width of the rotating arm 602 is smaller than the width of the U-shaped openings on both sides of the side wing ear piece installation frame 5. After connection, the side wing ear piece installation frame 5 completely covers the rotating arm, and does not affect the folding operation of the side wing ear piece 6.

[0037] like Figure 1 , 7 As shown, the slider 4 is specifically configured to be an I-shaped, including two upper and lower horizontal plates and a middle vertical plate, wherein one of the horizontal plates is embedded and connected to the slider positioning plate 204, and the other horizontal plate is hinged to the rotating arm 602 through the first pin shaft 8, and the two first pin shafts 8 are symmetrically arranged in the first sliding hole 401 and the second sliding hole 402. Specifically, the first sliding hole 401 and the second sliding hole 402 are both configured to be waist-shaped holes, and are symmetrically distributed on the two horizontal plates of the slider 4.

[0038] In addition, a speaker 7 is installed on the side ear piece 6. The arrangement of the speaker 7 is convenient for passengers to listen to music better and improves the riding comfort.

[0039] The working process of the present invention is as follows:

[0040] like Figure 8-10As shown, the drive assembly 3 of the present invention includes a motor 301, a gear set 302 and a lead screw 303. The motor 301 is electrically connected to the control system in the car and is controlled to open or close by a corresponding button. The invention transmits the rotation of the vertically placed motor 301 to the horizontally placed lead screw 303 through the gear set 302, and drives the lead screw 303 to rotate. Because the lead screw 303 is connected to the middle of the slider 4 through a thread, the rotation of the lead screw 303 drives the slider 4 to move horizontally, and drives the side wing ear piece 6 to rotate and open and close through the hinge. Figure 2 , 9 As shown, the wing ear piece 6 is in a closed state, at which time the first pin shaft 8 and the second pin shaft 9 are located at the inner sides of the first sliding hole 401 and the second sliding hole 402 .

[0041] Specifically, when the motor 301 is started and drives the lead screw 303 to rotate through the gear set 302, and drives the slider 4 to move downward, the rotation point at the second pin shaft 9 on the side wing ear piece 6 is fixed and cannot be moved, and drives the slider 4 to drive the two symmetrically arranged first pin shafts 8 to move synchronously outward along the first sliding hole 401 and the second sliding hole 402 through the rotating arm 602. At this time, with the fixed second pin shaft 9 as the rotation axis, the two side wing ears 6 flip inward, and the flipping and opening of the two side wing ears is realized quickly and stably. Fig.10 As shown, at this time, the side wing ear pieces 6 are close to the ears on both sides of the human body, which is convenient for passengers to rest or listen to music. The motor rotates in the opposite direction, and the side wing ear pieces 6 are driven by the slider to unfold outwards and return to the closed state.

[0042] The invention is cleverly designed to realize the motorized folding operation of the side wing ears by driving the side wing ears with a motor, and at the same time, the speakers are concentrated in the side wing ears to realize the function of a music headrest. At the same time, the side wing ears can also be designed as comfortable side pillows to improve the customer's sleeping experience.

[0043] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
