[0029] The present application makes improvements and innovations and proposes the following embodiments.

[0030] In some embodiments, see Figures 1 to 4 , provides a car seat, comprising: A seat cushion 1 is slidably arranged in the car; A backrest 2, the backrest 2 being hinged to the seat cushion 1; The lumbar support structure 3 includes a lifting assembly 31, an angle adjustment assembly 32, and a lumbar support assembly 33; the lifting assembly 31 is fixedly arranged inside the backrest 2, the angle adjustment assembly 32 is detachably arranged on the lifting part of the lifting assembly 31, and the lumbar support assembly 33 is fixedly connected to the angle adjustment assembly 32; Temperature control structure 4; the temperature control structure 4 includes: a fan 41, a first ventilation duct 42; 42, a second ventilation duct 43, and a third ventilation duct 44; the fan 41 is fixedly arranged at the lower part of the seat cushion 1, and the air inlet of the fan 41 is connected to the air outlet of the air conditioner of the car, and the first ventilation duct 42; 42 is located in the seat cushion 1; the first ventilation duct 42; 42 is connected to the air outlet of the fan 41; the second ventilation duct 43 is fixedly arranged on the outside of the backrest 2, and the second ventilation duct 43 is connected to the air outlet of the fan 41, the air outlet of the second ventilation duct 43 is located at the upper part of the backrest 2, and the air outlet direction of the second ventilation duct 43 diffuses along the surface of the backrest 2; the third ventilation duct 44 is connected to the second ventilation duct 43, and the air outlet of the third ventilation duct 44 blows toward the lumbar support assembly 33.

[0031] By setting the fan 41, the ventilation of the seat cushion 1 and the backrest 2 is enhanced, and the heat and moisture generated by the user are taken away in time, ensuring that the seat cushion 1 and the backrest 2 are dry and breathable. When the air conditioning wind is hot air, the air conditioning hot air can be directly applied to the seat cushion 1 and the backrest 2 of the car seat through the delivery of the fan 41, thereby increasing the temperature of the seat and improving the comfort of the seat. Using the air conditioning wind to dissipate heat or heat can fully improve the utilization rate of the vehicle air conditioner, and reduce the need to separately set up heating elements and cooling elements to realize the temperature adjustment function of the temperature adjustment structure 4 on the seat. The use of components is reduced, making the temperature adjustment structure 4 simple, easy to repair and replace, and reducing production costs.

[0032] Providing the lumbar support structure 3 on the backrest 2 can effectively improve the user's comfort when driving, and the cooperation between the lifting component 31 and the angle adjustment component 32 of the lumbar support structure 3 can achieve the adjustment of the position and angle of the lumbar support component 33 to meet different user needs.

[0033] The outer surface of the seat cushion 1 and the backrest 2 is covered with an outer skin layer, and ventilation holes are opened on the outer skin layer; the edge of the backrest 2 is hinged to the seat cushion 1, and the lumbar support structure 3 is located at the lower part of the backrest 2. The outer skin layer can improve the comfort of the seat, and the ventilation holes can improve the air permeability of the outer skin layer, and at the same time, it can facilitate the first ventilation pipe 42; the air conditioning wind in 42 can flow out from the ventilation holes, which is convenient for improving the heat dissipation or heating efficiency of the seat.

[0034] In some embodiments, the lifting assembly 31 includes a first motor 311, a screw 312, a slider 313, a guide rod 314, and a moving plate 315; the first motor 311 is fixedly connected to the backrest 2, the output end of the first motor 311 is transmission-connected to the screw 312, the slider 313 is threadedly matched with the screw 312, the slider 313 is slidably connected to the guide rod 314; the moving plate 315 is fixedly connected to the slider 313. The screw 312 driven by the first motor 311 rotates, and the guide rod 314 limits the rotation of the slider 313, so that the rotating screw 312 drives the slider 313 to move up and down on the screw 312, thereby realizing the lifting and lowering movement of the moving plate 315, and finally realizing the lifting and lowering movement of the lumbar support assembly 33, so as to adjust the lifting position of the lumbar support assembly 33. The lifting assembly 31 has a simple structure and is practical and reliable.

[0035] Specifically, the guide rod 314 and the screw rod 312 are parallel to each other, the guide rod 314 is fixedly connected to the motor, and the slider 313 is provided with a through hole for the guide rod 314 to pass through and slide relatively.

[0036] In some embodiments, the angle adjustment assembly 32 includes a block 321, a second motor 322, and an adjustment plate 323; the block 321 is hinged to the adjustment plate 323, the second motor 322 has a telescopic portion 324, and the telescopic portion 324 is hinged to the adjustment plate 323; the block 321 and the second motor 322 are both snap-connected to the moving plate 315, and the block 321 and the second motor 322 are spaced apart. The telescopic portion 324 of the second motor 322 can push the adjustment plate 323 to rotate around the block 321 when it is extended and retracted, thereby realizing the tilt angle of the adjustment plate 323, and finally realizing the adjustment of the tilt angle of the waist support assembly 33. The angle adjustment assembly 32 has a simple structure, is practical and reliable.

[0037] Specifically, the transmission end of the second motor 322 is threadedly connected to the telescopic part 324, and a limiting rod 325 is also provided on the second motor 322. The telescopic part 324 is sleeved on the limiting rod 325, and the telescopic part 324 and the adjustment plate 323 are hinged through a connecting rod 326. When the second motor 322 rotates, the telescopic part 324 cannot rotate with the transmission end due to the limitation of the limiting rod 325, so the telescopic part 324 telescopes and moves, and the telescopic part 324 pushes the rotation of the adjustment plate 323 through the connecting rod 326 to adjust the angle of the adjustment plate 323.

[0038] In some embodiments, a slot 316 is provided on the movable plate 315, and a limit block matching the slot 316 is provided at the bottom of the block 321 and the second motor 322; the limit block is slidably locked in the slot 316. The provision of the slot 316 and the limit block can quickly realize the detachable connection between the movable plate 315 and the block 321 and the second motor 322.

[0039] In some embodiments, the lumbar support assembly 33 includes a pressure plate 331, a connecting plate 332, a side plate 333, and a support rod 334; a receiving groove 3231 is opened on the adjustment plate 323, and the receiving groove 3231 can be clamped with a spring 6; one end of the connecting plate 332 is fixedly connected to the pressure plate 331, and the other end is abutted against the spring 6; the side plate 333 is hinged to the connecting plate 332, one end of the support rod 334 is hinged to the side plate 333, and the other end is hinged to the adjustment plate 323. When the user uses the lumbar support, the user's body will be pressed on the pressure plate 331, and the connecting plate 332 will move the compression spring 6. During the movement of the connecting plate 332, the side plate 333 will rotate. Due to the connection between the side plate 333 and the support rod 334, the side plate 333 can fit the user's waist more closely. When the user's waist is smaller, the connecting plate 332 moves a greater distance and the side plate 333 rotates at a greater angle. When the user's waist is larger, the connecting plate 332 moves a smaller distance and the side plate 333 rotates at a smaller angle. Corresponding to users of different body shapes, the side plate 333 can fit the user's waist position, thereby improving the adaptability of the lumbar support assembly 33.

[0040] In some embodiments, the pressing plate 331 and the side plate 333 are both covered with a breathable layer 5. Providing the breathable layer 5 can improve the breathability of the pressing plate 331 and the side plate 333 after contacting the skin.

[0041] Specifically, the breathable layer 5 is made of fabric with pores of a predetermined size.

[0042] In some embodiments, a plurality of protrusions 51 are evenly arranged on the breathable layer 5. The protrusions 51 can massage the user's waist, and at the same time, the protrusions 51 can increase the gap between the user's waist and the breathable layer 5 to facilitate air circulation and achieve heat dissipation or heating.

[0043] In some embodiments, heating wires are provided in both the backrest 2 and the seat cushion 1. The heating wires can compensate for the fact that when the outdoor temperature is too low, the air conditioning wind takes a long time to heat the seat, and auxiliary heating by the heating wires can improve the effect of seat heating.

[0044] In some embodiments, there are multiple support rods 334, and the multiple support rods 334 are spaced apart along the extension direction of the receiving groove 3231. Providing multiple support rods 334 can increase the maximum upper limit of the force of the side plate 333, and make the force of the side plate 333 more uniform and reasonable.

[0045] In some embodiments, the number of the side panels 333 is two, and the two side panels 333 are symmetrically arranged on both sides of the connecting plate 332. This design is reasonably distributed.

[0046] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
