[0026] This embodiment provides a universal car seat bracket, including:

[0027] Bottom beam 1 is fixedly installed inside the chassis;

[0028] The slide rail assembly 2 is adjustablely movable on the bottom beam 1;

[0029] A support component 3 is movably disposed on the upper part of the slide rail assembly 2, and the support component 3 is used to mount a car seat;

[0030] A front-to-back adjustment component 4 is provided on the support component 3 for adjusting the front-to-back movement of the support component 3;

[0031] A limiting mechanism is provided on the front-rear adjustment component 4 to limit the adjustment of the front-rear adjustment component 4 to its foremost position. As can be seen from the attached drawings, the overall mechanism design of the above-mentioned components is simple, which not only simplifies the assembly process but also saves costs.

[0032] In this embodiment, specifically, the bottom beam 1 consists of two parallel beams spaced apart, with an opening at the top. The slide rail assembly 2 is disposed between the bottom beams 1. The bottom beam 1 is made of channel steel. The bottom of the bottom beam 1 has a positioning pin 10 and a mounting block 11. The positioning pin 10 is inserted and positioned inside the chassis, and the mounting block 11 and screws are used to lock and fix it inside the chassis.

[0033] In this embodiment, specifically, the slide rail assembly 2 includes a slide rod 20, a slide rail 21, a mounting plate 22, a linear motor 23, a pin 24, and a spring 25. The slide rod 20 is fixed at both ends inside the bottom beam 1, and a locking block 26 is also fixed on the slide rod 20. The slide rail 21 is slidably mounted on the slide rod 20. The mounting plate 22 is fixed at both ends between the slide rails 21. The linear motor 23 is fixed on the mounting plate 22. The pin 24 is fixedly connected to the output end of the linear motor 23 and passes through the mounting plate 22. The locking block 26 has a locking hole 260 through which the pin 24 passes. The slide rail 21 is fixed by passing through the lock hole 260. A spring 25 is sleeved on the pin 24. The slide rod 20 is provided with a positioning groove. When the linear motor 23 drives the pin 24 to retract, it disengages from the lock hole 260. When the slide rail 21 moves to a stop, one end of the pin 24 is inserted into the positioning groove for fixation. Therefore, when it is necessary to adjust back and forth, the linear motor 23 is started to drive the pin 24 to retract and disengage from the lock hole 260. At this time, the slide rail 21 and the lock block 26 are unlocked. When the slide rail 21 moves to the appropriate position, the linear motor 23 pushes the pin 24 to insert into the positioning groove for positioning and stopping.

[0034] In this embodiment, more specifically, the support assembly 3 includes a connecting block 30, a front rocker block 31, a rear rocker block 32, a first support rod 33, a second support rod 34, and a support beam 35. The connecting block 30 is fixed on the slide rail 21. The lower ends of the front rocker block 31 and the rear rocker block 32 are rotatably connected to the connecting block 30. The inner side of the support beam 35 is rotatably connected to the upper ends of the front rocker block 31 and the rear rocker block 32. The two ends of the first support rod 33 are fixed between the front rocker blocks 31, and the two ends of the second support rod 34 are fixed between the rear rocker blocks 32. The car seat is mounted and fixed on the support beam 35. Under the combined action of the front rocker block 31 and the rear rocker block 32, the synchronous movement of the support beam 35 is achieved.

[0035] In this embodiment, specifically, the front-to-back adjustment assembly 4 includes a servo motor 41, a rotating shaft 42, a gear 43, and a sector gear 44. The servo motor 41 is fixed to the outside of the support beam 35. The rotating shaft 42 passes through the support beam 35 and is fixedly connected to the output end of the servo motor 41. The gear 43 is fixed on the rotating shaft 42 and located inside the support beam 35. The sector gear 44 is fixed on the second support rod 34 and meshes with the gear 43. When the servo motor 41 is working, it drives the rotating shaft 42 and the gear 43 to rotate. When the gear 43 and the sector gear 44 mesh, they drive the rear rocker block 32 to rotate, thereby allowing the support beam 35 to be adjusted in height as a whole. The front-to-back adjustment assembly 4 has a simple structure, reasonable design, can reduce costs, and is easy to adjust, making it universal for use in car seat installations.

[0036] In this embodiment, the limiting mechanism includes a limiting flange 300 bent and formed on the connecting block 30, and a limiting protrusion 320 provided on the front rocker block 31 and the rear rocker block 32. When the front and rear adjustment component 4 is adjusted to the frontmost position, the limiting protrusion 320 abuts against the limiting flange 300 to limit the maximum height. When adjusted downward, the limiting protrusion 320 gradually moves away from the limiting flange 300.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
