[0002] According to the published patent CN215552729U, a car seat backrest support includes a support body with an internal cavity and a square hole communicating with the cavity on the side. Two slide rails are fixedly connected to the inner side of the support body, and a connecting rod is slidably connected between the two slide rails. A massage cylinder is rotatably connected to the middle of the connecting rod via a bearing. A first rotating shaft is rotatably connected to the upper inner side of the support body via a bearing. After the above device is completed, a chain drives the connecting rod to move, causing one side of the massage cylinder to roll. When the motor rotates in both directions, the massage cylinder rolls back and forth, thus massaging the driver's back and effectively relieving driver fatigue. However, it still has the following shortcomings:

[0003] After the above equipment is completed, it only performs a simple massage operation. When facing bumpy roads, the seat cannot provide shock absorption, resulting in a poor riding experience for passengers and causing discomfort. Therefore, we propose a car seat backrest bracket. Utility Model Content

[0004] The purpose of this utility model is to provide a car seat backrest bracket that, through a shock-absorbing mechanism and an adjustment mechanism, solves the problem that the seat cannot provide shock absorption when facing bumpy roads, resulting in a poor riding experience and discomfort for passengers, as it only performs simple massage operations.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a car seat backrest bracket, including a support plate, a plurality of fixing plates are fixedly connected to the outer wall of the support plate, and a shock-absorbing mechanism is provided on the bottom outer wall of the support plate.

[0007] The shock-absorbing mechanism includes several sliding rods. The bottom outer wall of the support plate is fixedly connected to the outer wall of the sliding rod. A spring is sleeved on the outer wall of the sliding rod. A sleeve is slidably connected to the outer wall of the sliding rod. Several joint shafts are fixedly connected to the bottom outer wall of the support plate. A connecting plate is rotatably connected to the outer wall of the joint shaft. A second joint shaft is rotatably connected to the inner wall of the connecting plate. A base plate is fixedly connected to the outer wall of the sleeve away from the support plate. Several sliding grooves are formed on the inner wall of the base plate. A slider is fixedly connected to the outer wall of the second joint shaft. The outer wall of the slider is slidably connected to the inner wall of the sliding groove.

[0008] Furthermore, the inner wall of the slider is provided with a circular groove, and a fixing rod is fixedly connected to the inner wall of the groove. The outer wall of the fixing rod is slidably connected to the inner wall of the circular groove. Several pressure springs are sleeved on the outer wall of the fixing rod, and an adjustment mechanism is provided on the bottom outer wall of the support plate.

[0009] Furthermore, the adjustment mechanism includes a support frame, the outer wall of which is fixedly connected to the bottom outer wall of the support plate.

[0010] Furthermore, a first motor is fixedly connected to the inner wall of the support frame, and a rotating shaft is fixedly connected to the bottom output end of the first motor via a coupling.

[0011] Furthermore, a crown gear is fixedly connected to the outer wall of the rotating shaft on the side away from the support frame, and several L-plates are fixedly connected to the bottom outer wall of the support plate.

[0012] Furthermore, a roller is rotatably connected to the inner wall of the L-plate, and a gear is fixedly connected to the outer wall of the roller.

[0013] Furthermore, the outer wall of the gear meshes with the outer wall of the crown gear, and a number of sprockets are fixedly connected to the outer wall of the roller, with a chain drivingly connected to the outer wall of the sprockets.

[0014] Furthermore, a rolling rod is rotatably connected to the inner wall of the fixed plate, and a plurality of sprockets are fixedly connected to the outer wall of the rolling rod. The outer wall of the sprockets is drivenly connected to the inner wall of the chain, and a backrest bracket is fixedly connected to the outer wall of the rolling rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a sliding rod and a pressure spring. When the support plate moves, it moves the joint shaft, which in turn moves the connecting plate in an arc shape. The connecting plate then moves the second joint shaft, which in turn moves the slider in the groove. Simultaneously, the slider slides on the fixed rod, compressing the pressure spring as it moves. This enhances ride comfort and effectively absorbs and disperses vibrations and impacts from the vehicle body. Especially on uneven roads, by mitigating these vibrations, passengers can experience a smoother and more comfortable ride, reducing discomfort caused by long journeys.

[0017] 2. This utility model incorporates a crown gear and a chain. After the first motor starts, it drives the shaft to rotate, and the crown gear rotates along with the shaft. As the crown gear rotates, it drives the gear to rotate, which in turn drives the sprocket. As the sprocket rotates, the chain drives the second sprocket to rotate, and the rolling rod rotates along with the second sprocket. This reduces muscle fatigue. By adjusting the seat angle, passengers can choose a more relaxed posture, thereby reducing muscle tension in the back and legs. Especially during long-distance driving, the correct seat angle can effectively alleviate muscle fatigue caused by maintaining poor posture and increase the comfort of long-distance travel.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is a car seat backrest bracket, including a support plate 1. Several fixing plates 101 are fixedly connected to the outer wall of the support plate 1. A shock-absorbing mechanism 2 is provided on the bottom outer wall of the support plate 1. The fixing plates 101 limit the rolling rod 310 to prevent it from shaking when rotating. The shock-absorbing mechanism 2 includes several sliding rods 201. The bottom outer wall of the support plate 1 is fixedly connected to the outer wall of the sliding rods 201. A spring 202 is sleeved on the outer wall of the sliding rod 201. When the spring 202 moves within the sliding rod 201... When 01 is compressed, spring 202 will not misalign, ensuring its normal operation. A sleeve 203 is slidably connected to the outer wall of the sliding rod 201. Several joint shafts 204 are fixedly connected to the bottom outer wall of the support plate 1. A connecting plate 205 is rotatably connected to the outer wall of each joint shaft 204, and a joint shaft 206 is rotatably connected to the inner wall of the connecting plate 205. When the support plate 1 moves, it moves the joint shafts 204, which in turn move the connecting plate 205 in an arc. As the connecting plate 205 moves, it also moves the joint shafts 206. The movement of joint shaft 206 enables kinetic energy transfer between parts. A base plate 207 is fixedly connected to the outer wall of sleeve 203 on the side away from support plate 1. Several sliding grooves 208 are formed on the inner wall of base plate 207. A slider 209 is fixedly connected to the outer wall of joint shaft 206. When slider 209 slides in the sliding groove 208, it will not swing left or right, maintaining linear motion. The outer wall of slider 209 is slidably connected to the inner wall of the sliding groove 208. A circular groove 210 is formed on the inner wall of slider 209. A fixed rod 211 is fixedly connected to the inner wall of the groove 208. When the slider 209 slides on the fixed rod 211, the slider 209 will not wobble, keeping the slider 209 in a straight line. The outer wall of the fixed rod 211 is slidably connected to the inner wall of the circular groove 210. Several pressure springs 212 are sleeved on the outer wall of the fixed rod 211. An adjustment mechanism 3 is provided on the bottom outer wall of the support plate 1. When the pressure springs 212 are squeezed on the fixed rod 211, the pressure springs 212 will not be misaligned, keeping the pressure springs 212 in normal use.

[0029] The adjustment mechanism 3 includes a support frame 301. The outer wall of the support frame 301 is fixedly connected to the bottom outer wall of the support plate 1. A first motor 302 is fixedly connected to the inner wall of the support frame 301. When the operator starts the first motor 302, a rotating shaft 303 is fixedly connected to the bottom output end of the first motor 302 via a coupling. A crown gear 304 is fixedly connected to the outer wall of the rotating shaft 303 on the side away from the support frame 301. After the first motor 302 starts, it will rotate the rotating shaft 303, and then the rotating shaft 303 will rotate the crown gear 304, realizing the kinetic energy transfer between the parts. Several L-plates 305 are fixedly connected to the bottom outer wall of the support plate 1. Rollers 306 are rotatably connected to the inner wall of the L-plates 305. Gears 307 are fixedly connected to the outer wall of the rollers 306. When the crown gear 304 rotates, it will rotate the gear 307, and then the rollers 306 will rotate with the gear 307, completing the kinetic energy transfer between the parts.

[0030] The outer wall of gear 307 meshes with the outer wall of crown gear 304. Several sprockets 308 are fixedly connected to the outer wall of roller 306. A chain 309 is drivenly connected to the outer wall of sprocket 308. When roller 306 rotates, it will drive sprocket 308 to rotate. Then sprocket 308 will move with chain 309, realizing the kinetic energy transfer process between parts. A rolling rod 310 is rotatably connected to the inner wall of fixed plate 101. Several sprockets 311 are fixedly connected to the outer wall of rolling rod 310. The outer wall of sprocket 311 is drivenly connected to the inner wall of chain 309. A backrest bracket 312 is fixedly connected to the outer wall of rolling rod 310. When chain 309 moves, it will drive sprocket 311 to rotate. Then sprocket 311 will drive rolling rod 310 to rotate. When rolling rod 310 rotates, it will drive backrest bracket 312 to rotate, which makes it convenient for operators to adjust the seat back angle.

[0031] One specific application of this embodiment is:

[0032] When the equipment is used by the operator, the support plate 1 moves when the equipment is subjected to bumps. As the support plate 1 moves, it causes the sliding rod 201 to slide within the sleeve 203. Simultaneously, the sliding rod 201 compresses the spring 202, which then reduces the impact of the bumps. The movement of the support plate 1 also causes the joint shaft 204 to move, which in turn causes the connecting plate 205 to move in an arc. The movement of the connecting plate 205 then causes the joint shaft 206 to move, which in turn causes the slider 209 to slide within the groove 208. Simultaneously, the slider 209 slides on the fixed rod 211. As the slider 209 moves, it compresses the pressure spring 212. The pressure spring 212 further reduces the impact force generated by bumps. At the same time, the first motor 302 can be started when adjusting the angle of the seat back support. After the first motor 302 is started, it will drive the shaft 303 to rotate. At the same time, the crown gear 304 will rotate with the shaft 303. When the crown gear 304 rotates, it will drive the gear 307 to rotate. Then the gear 307 will drive the sprocket 308 to rotate. When the sprocket 308 rotates, it will drive the second sprocket 311 to rotate through the chain 309. Then the rolling rod 310 will rotate with the second sprocket 311. When the rolling rod 310 rotates, it will drive the back support 312 to rotate. When the back support 312 rotates, it will change the angle of the seat back support, making it convenient for the operator to adjust to a suitable sitting posture.
