[0003] In the prior art, the backrests of three-row automobile seats usually allow passengers to adjust the front-back position and tilt angle to adapt to different sitting postures. However, traditional backrests of three-row automobile seats often lack the function of height adjustment. Due to the differences in the heights of different passengers, passengers cannot adjust according to their own heights. This limitation makes it impossible for passengers' heads and necks to receive sufficient support, which will not only reduce the comfort of passengers, but also affect the driving experience of passengers during long-distance travel due to the discomfort of the head and neck.

[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0021] Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1 - 4 shown, the present utility model provides a three-row seat backrest structure for an automobile, including a three-row seat body 1. A bottom of the three-row seat body 1 is fixedly connected with an adjusting mechanism 2. The adjusting mechanism 2 includes two mounting plates 201 and a bottom plate 210. A driving motor 202 is disposed on an outer surface of the two mounting plates 201. An output end of the driving motor 202 penetrates through the outer surface of the mounting plate 201 and extends to one side. The output end of the driving motor 202 is fixedly connected with a rotating rod 203. Two limiting plates 204 are symmetrically rotatably connected to an outer surface of the rotating rod 203. Inner walls of the two limiting plates 204 are rotatably connected with rotating plates 205. The outer surface of the rotating rod 203 is fixedly connected with an inner wall of the rotating plate 205. Connecting rods 206 are disposed on inner walls of the two rotating plates 205. Swing plates 207 are rotatably connected to outer surfaces of the two connecting rods 206. Rotating columns 208 are rotatably connected to inner walls of the two swing plates 207. One ends of the two rotating columns 208 are fixedly connected with fixed plates 209. Sliding columns 211 are fixedly connected to top of the bottom plate 210 near four corners. Sliding sleeves 213 are slidably connected to outer surfaces of the four sliding columns 211. A support plate 212 is fixedly connected to tops of the four sliding sleeves 213. The top of the support plate 212 is fixedly connected with the bottom of the three-row seat body 1. Bottoms of the two mounting plates 201 are fixedly connected with the top of the bottom plate 210.

[0023] The effect achieved by the entire Embodiment 1 is that when using the height adjustment function of the three-row seat back of the vehicle, first start the drive motor 202 on the mounting plate 201, and drive the rotating rod 203 to rotate forward with its output end. During the rotation of the rotating rod 203, the rotating plate 205 can be driven to swing accordingly. And during the swinging process of the rotating plate 205, the limiting plate 204 is used to limit and guide the rotating plate 205, so that the rotating plate 205 swings stably within a certain range. Subsequently, when the rotating plate 205 swings, through the rotation of the connecting rod 206, the swinging plate 207 can be further driven to swing. This swinging action will cause the rotating column 208 and the fixing plate 209 to rise accordingly. While the fixing plate 209 rises, it can effectively drive the support plate 212 to rise together. And during the rising process of the support plate 212, the sliding sleeve 213 at the bottom of the support plate 212 will slide smoothly on the outer surface of the sliding column 211 to ensure the stability of the rising action and make the height adjustment of the seat back more stable. When the height needs to be lowered, just start the drive motor 202 again, and the support plate 212 can be driven to lower by the reverse rotation of the drive motor 202. Under the action of the adjustment mechanism 2, the three-row seat back can be adjusted to meet the height differences of different passengers, which not only improves the comfort of the passengers but also guarantees the driving experience of the passengers.

[0024] Embodiment 2 is as Figures 1 - 4 shown. A plurality of connecting grooves 3 are equidistantly formed on the outer surface of the three-row seat body 1. A plurality of connecting plates 31 are equidistantly fixedly connected to the outer surface of the three-row seat body 1. The outer surfaces of the plurality of connecting plates 31 are all provided with telescopic rods 32. The telescopic ends of the plurality of telescopic rods 32 slide through the outer surface of the connecting plates 31 and extend to one side. The telescopic ends of the plurality of telescopic rods 32 are all provided with cushion pads 33.

[0025] The effect achieved by the entire Embodiment 2 is that when using the seat back, the passenger can start the telescopic rod 32 on the connecting plate 31, and accurately push the cushion pad 33 through the connecting groove 3 forward with its telescopic end until the cushion pad 33 closely and comfortably fits the passenger's waist, ensuring that the cushion pad 33 can fit the waist curve of the passenger and provide effective support. This not only avoids the waist discomfort that may be caused by a long sitting posture but also helps to maintain the normal physiological curvature of the waist, thereby improving the practicality of the three-row seat body 1.

[0026] Working principle: When in use, first start the driving motor 202, and drive the rotating rod 203 to rotate forward with its output end. During the rotation of the rotating rod 203, the rotating plate 205 can be driven to swing. And during the swinging process of the rotating plate 205, the limiting plate 204 is used to limit and guide the rotating plate 205. Subsequently, when the rotating plate 205 swings, through the rotation of the connecting rod 206, the swinging plate 207 can be further driven to swing. This swinging action will cause the rotating column 208 and the fixing plate 209 to rise accordingly. While the fixing plate 209 rises, the supporting plate 212 can be effectively driven to rise together. And during the rising process of the supporting plate 212, the sliding sleeve 213 at the bottom of the supporting plate 212 will smoothly slide on the outer surface of the sliding column 211. And the passenger can start the telescopic rod 32 on the connecting plate 31, and precisely push the cushion 33 to move forward through the connecting groove 3 with its telescopic end until the cushion 33 closely and comfortably fits the passenger's waist, ensuring that the cushion 33 can fit the waist curve of the passenger and provide effective support.

[0027] The above is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
