[0025] See Figures 1-10 As shown, the technical solution adopted in this specific embodiment is as follows: It includes a primary support 4, a rotating connecting mechanism 5 installed at the bottom of the primary support 4, mounting clips 6 installed on both sides of the rotating connecting mechanism 5, and a secondary support 3 installed inside the primary support 4. A connecting support 2 is fixedly connected to the upper end of the secondary support 3. One side of the connecting support 2 is connected to the lumbar support 1. The connecting support 2 includes a secondary support connecting frame 211. A limiting spring plate 210 is fixedly connected to the top of the secondary support connecting frame 211. An outer baffle 27 is installed on one side of the limiting spring plate 210, and a lumbar support connecting frame 26 is installed on the other side of the limiting spring plate 210. An inner locking tooth 25 is provided on the inner side of the lumbar support connecting frame 26, and a limiting outer shell 24 is provided on the outer side of the lumbar support connecting frame 26. An outer locking tooth 23 is provided on the inner side of the limiting outer shell 24. A limiting tooth 22 is installed on the outer side of the pressing button 21, and the outer locking tooth 23 and the inner locking tooth 25 both engage with the limiting tooth 22.

[0026] More specifically, a lumbar support cushion 101 is provided on the outer side of the lumbar support 1. The lumbar support cushion 101 is a three-section lumbar support, and there are gaps between each section of the lumbar support cushion 101. The lumbar support cushion 101 increases the comfort of the lumbar support 1, while the gaps facilitate air circulation and increase its heat dissipation effect.

[0027] More specifically, the inner side of the outer baffle 27 is provided with damping teeth 28, and a damping baffle 29 is installed on the inner side of the outer baffle 27, with the damping baffle 29 cooperating with the damping teeth 28. When rotating to make the waist-support connecting frame 26 and the secondary support connecting frame 211, the damping baffle 29 and the damping teeth 28 can provide damping and make a mechanical collision sound, thereby enhancing the user experience.

[0028] More specifically, the outer end of the lumbar support connecting bracket 26 is bolted to the lumbar support 1, and the outer end of the secondary support connecting bracket 211 is fixedly connected to the secondary support 3. By connecting the lumbar support 1 and the secondary support 3 through the lumbar support connecting bracket 26 and the secondary support connecting bracket 211 respectively, the lumbar support 1 can be better installed and used.

[0029] More specifically, the secondary support 3 includes a support connecting plate 32. A limiting groove hole 33 is formed in the middle of the support connecting plate 32. A limiting shaft 34 slides and engages with the limiting groove hole 33. An adjustment button 31 is fixedly connected to the outer end of the limiting shaft 34, and a positioning protrusion 35 is installed on the adjustment button 31. When it is necessary to adjust the relative height between the secondary support 3 and the primary support 4, the user only needs to press the adjustment button 31. The adjustment button 31 squeezes the limiting shaft 34, causing the limiting shaft 34 to disengage from the limiting groove hole 33. At this time, the user can drag the support connecting plate 32 to adjust the relative height between the secondary support 3 and the primary support 4. After adjustment, simply loosen the adjustment button 31, and the internal spring will push up the adjustment button 31, causing the limiting shaft 34 to lock the support connecting plate 32.

[0030] More specifically, the rotary connection mechanism 5 includes a mounting clip connecting piece 54. One side of the mounting clip connecting piece 54 is connected to its mounting clip 6. The inner side of the mounting clip connecting piece 54 is provided with an outer ring tooth 52, and an insert 53 is installed in the inner cavity of the mounting clip connecting piece 54. One side of the insert 53 abuts against the outer ring tooth 52, and the middle of the other side of the outer ring tooth 52 abuts against an elliptical cam 56. The elliptical cam 56 is fixedly connected to a rotary locking rod 57. The outer end of the rotary locking rod 57 is connected to a wave block 51. A pressure spring 55 is provided on the side of the outer ring tooth 52 near its elliptical cam 56. When the user moves the oscillating block 51, the oscillating block 51 will drive its rotating locking rod 57 and elliptical cam 56, so that the elliptical cam 56 no longer abuts against the insert 53. At this time, the insert 53 has a certain amount of room to move, and the angle between its mounting clip 6 and the first-stage bracket 4 can be adjusted. Under the operation of the pressure spring 55, the insert 53 and the outer ring tooth 52 will provide a certain damping feeling and make a mechanical collision sound, but it can still be rotated and adjusted. When the elliptical cam 56 abuts against the insert 53, the insert 53 will abut against its outer ring tooth 52, thereby realizing the locking operation.

[0031] The working principle of this utility model is as follows: During use, the operator simply installs the structure to the designated position using the mounting clip 6. When the angle of the lumbar support 1 needs adjustment, the user simply presses the pressing button 21, causing the limiting teeth 22 to disengage from the outer teeth 23 and inner teeth 25, allowing the outer teeth 23 and inner teeth 25 to rotate independently. At this time, the lumbar support connecting frame 26 and the secondary support connecting frame 211 can rotate, thereby adjusting the support angle of the lumbar support 1. By adjusting the angle of the lumbar support 1, the rider can find a comfortable support angle. When adjusting the height of the lumbar support 1, the user only needs to press the adjustment button 31 to adjust the relative height between the secondary support 3 and the primary support 4, thereby adjusting the support height of the lumbar support 1. This provides a certain support effect for the back of the rear passenger, ensuring the comfort and safety of the rear passenger. When the rider needs to lie down to rest, the device can be flattened by rotating the connecting mechanism 5, making it easier for the rider to rest appropriately. When it is necessary to flatten the lumbar support 1 and the primary support 4, the user only needs to move the undulating block 51 to adjust the support angle of the flattened lumbar support 1 and the primary support 4.

[0032] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
