[0002] With the rapid development of the automotive industry and the increasing demands of consumers for a superior riding experience, car seat design is increasingly focusing on comfort and functionality. However, in the current technology, traditional car seats often only provide basic seating functions, and their design is limited to fixed shapes and positions, making it difficult to meet users' diverse needs for seat flexibility, comfort, and practicality. Traditional seat adjustment methods, such as fixing the seat body and support structure with bolts or welding, limit the seat's rotation adjustment function, affecting the user experience. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a multi-directionally adjustable car seat to solve the problems mentioned in the background art.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A multi-directional adjustable car seat includes a seat body. An upper cylinder is fixedly mounted on the bottom outer wall of the seat body. A lower cylinder is located at the bottom of the upper cylinder. A sliding seat is fixedly mounted on the bottom outer wall of the lower cylinder. A positioning plate is located at the bottom of the sliding seat. A mating groove is formed on the top outer wall of the lower cylinder. The inner wall of the mating groove and the bottom outer wall of the upper cylinder are clearance-fitted. An annular groove is formed on the bottom outer wall of the upper cylinder and the bottom inner wall of the mating groove. Equally spaced ball bearings are rolled along the inner wall of the annular groove. A vertically downward hydraulic push rod is fixedly mounted on the top inner wall of the upper cylinder. A limiting plate is fixedly mounted at the output end of the hydraulic push rod. Equally spaced limiting posts are fixedly mounted on the bottom outer wall of the limiting plate. A positioning plate is fixedly mounted on the bottom inner wall of the lower cylinder. Equally spaced positioning holes are formed on the top outer wall of the positioning plate. The inner wall of the positioning holes is adapted to the outer wall of the limiting posts.

[0006] As a preferred embodiment of a multi-directionally adjustable car seat, the top inner wall of the upper cylinder is fixedly provided with two vertically downward guide sleeves, and the top outer wall of the limiting plate is fixedly provided with two vertically upward guide rods, the outer walls of the guide rods and the inner walls of the guide sleeves being slidably connected.

[0007] As a preferred embodiment of a multi-directional adjustable car seat, the bottom outer wall of the sliding seat is fixedly provided with two slide rails, and the inner walls of both ends of the slide rails are provided with spring locking protrusions through openings. The top outer wall of the positioning plate is fixedly provided with multiple sets of slide grooves, and the outer walls of the corresponding slide grooves are slidably connected to the outer walls of the slide rails. The outer walls of the slide grooves are provided with equally spaced limiting holes, and the inner walls of the limiting holes are adapted to the spring locking protrusions. The top of the sliding seat is provided with a lever, and the lever is controlled and connected to the spring locking protrusions.

[0008] As a preferred embodiment of a multi-directionally adjustable car seat, the positioning plate has fixing plates fixed on both outer walls, and the top outer wall of the fixing plates has fixing holes, with matching bolts fitted on the inner walls of the fixing holes.

[0009] As a preferred embodiment of a multi-directionally adjustable car seat, two parallel pneumatic push rods are fixedly provided on the bottom outer wall of the seat body. The output ends of the two pneumatic push rods are provided with telescopic plates. The outer wall of the telescopic plates has two fixing holes, and the inner wall of the fixing holes is fixedly connected to the output ends of the pneumatic push rods.

[0010] As a preferred embodiment of a multi-directionally adjustable car seat, the top outer wall of the telescopic plate has a fixing groove, the inner wall of the fixing groove is fitted with a sponge pad, and the top outer wall of the sponge pad has an arc-shaped groove.

[0011] As a preferred embodiment of a multi-directionally adjustable car seat, a headrest is inserted into the top outer wall of the seat body.

[0012] The beneficial effects of this utility model are:

[0013] (1) This utility model greatly improves the rotational flexibility and stability of the seat body through the structural design of the upper and lower cylinders. The annular groove at the bottom of the upper cylinder is inlaid with equidistant balls. These balls effectively reduce the friction during rotation, allowing the seat body to rotate easily and meet the usage preferences of different users. At the same time, the durability and stability design of the balls ensure that the seat can maintain excellent rotational performance during long-term use. The ingenious combination of the hydraulic push rod and the limiting plate allows the seat to be quickly and stably positioned after rotation, further improving the safety and practicality of the seat. When the car seat needs to be adjusted in angle, the limiting plate is driven to rise by the hydraulic push rod, causing the limiting post to disengage from the positioning hole, so that the upper cylinder can rotate relative to the lower cylinder, thereby realizing the horizontal angle adjustment of the car seat.

[0014] (2) The present invention can control the spring locking protrusion to disengage from the limiting hole by the lever. At this time, the sliding seat can drive the seat body to slide along the slide rail, thereby realizing the position adjustment of the car seat. After the adjustment is completed, the lever can be pressed to make the spring locking protrusion re-insert into the limiting hole, thereby realizing the positioning of the seat. At the same time, the extension plate can be controlled to extend by the start push rod, and the user can put his / her legs on the sponge pad and enjoy comfortable leg support.

[0045] Working principle and usage process of this utility model:

[0046] When using this multi-directional adjustable car seat, the hydraulic push rod 11 first drives the limiting plate 12 to rise, causing the limiting post 13 to disengage from the positioning hole 10. At this time, the upper cylinder 2 can rotate relative to the lower cylinder 3 to achieve horizontal angle adjustment of the seat. After adjustment, the hydraulic push rod 11 drives the limiting plate 12 to fall, and the limiting post 13 inserts into the positioning hole 10 to fix the seat angle. Then, the lever 19 can control the spring locking protrusion 18 to disengage from the limiting hole 22, and the sliding seat 4 can slide along the slide rail 17 to adjust the fore-and-aft position of the seat. After adjustment, pressing the lever 19 causes the spring locking protrusion 18 to re-insert into the limiting hole 22 to lock the seat position. At the same time, the pneumatic push rod 25 can control the extension or retraction of the telescopic plate 26. When the telescopic plate 26 is extended, the user can rest their legs on the sponge pad 29 to enjoy comfortable leg support.
