Description

Technical Field

[0001] This invention relates to the technical field of child safety seats, and more particularly to a child safety seat. Background Technology

[0002] Child safety seats are core equipment for ensuring children's safety while traveling in vehicles. With the continuous improvement of user needs, modern child safety seats have generally integrated multiple adjustment functions, mainly including the overall horizontal rotation adjustment of the seat for forward or rear-facing installation, the tilt angle adjustment of the seat back for switching between reclining and sitting positions, and the lateral sliding adjustment of the seat body for easy movement towards the door to facilitate picking up and putting down the child. Some child safety seats with integrated adjustment structures have appeared on the market. By pulling the handle box, the direction adjustment mechanism and the angle adjustment mechanism can be unlocked simultaneously, or the angle stop, side slide stop, and rotation stop can be unlocked simultaneously through a single handle component, realizing one-button simultaneous unlocking of seat back angle adjustment, side slide, and rotation. There are also child safety seats with forward or rear-facing switching and angle locking mechanisms.

[0003] However, although the linkage between rotation and angle adjustment, or rotation and side sliding, has been achieved, the quick-release function of the seat body and the base has not been integrated at the same time. In actual use, parents often need to remove the entire seat body from the base for cleaning or replacement. In the existing technology, the disassembly of the seat body usually requires the operation of a separate unlocking structure or the use of tools, which cannot form a unified control system with rotation, angle adjustment, and side sliding adjustment. The operation is cumbersome and inefficient. In the existing child safety seats, the connection between the seat body and the base is mostly fixed with bolts or a complex buckle structure. When disassembling and assembling, multiple buckles need to be operated at the same time or tools are needed, which cannot achieve quick disassembly and installation. Some detachable designs are prone to loosening after long-term use, affecting riding safety. After long-term use, jamming or wear is prone to occur, resulting in unsmooth unlocking or unstable locking. Summary of the Invention

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention features a trigger mechanism in which the main body gear shift handle is slidably connected to the bottom of the main body seat and connected to the gear shift levers on both sides. The gear shift levers have inclined grooves that cooperate with the main body gear shift bar, while the main body seat has longitudinal movement grooves for guidance. This allows the user to not only move the main body gear shift bar smoothly within the inclined grooves and longitudinal movement grooves when pulling the main body gear shift handle, thereby accurately switching the gear position of the gear adjustment mechanism and facilitating convenient adjustment of the main body seat tilt angle, but also to transmit the pulling action of the main body gear shift handle synchronously to the gear shift transition sliding block in the seat rotation mechanism via a steel wire rope. This drives the rotating pin to disengage from the front reinforcing iron of the base, achieving simultaneous unlocking of gear position adjustment and axial rotation adjustment. This significantly simplifies the operation steps and greatly improves ease of use and adjustment efficiency.

[0022] 2. This invention incorporates a gear adjustment mechanism and a seat rotation mechanism. The gear adjustment mechanism has a gear slot at the bottom of the inner wall of the rotating seat. The gear slot, in conjunction with the gear adjustment bar of the main body, has multiple circular transverse sliding grooves to form a multi-gear limiting structure. Simultaneously, the main body iron bracket has a sliding groove, allowing the main body seat and the main body iron bracket to slide stably on the surface of the main body bar. The seat rotation mechanism, through the cooperation of the pin movable slot plate, the gear adjustment transition sliding bracket, the gear adjustment transition sliding block, and the gear adjustment transition spring, achieves precise radial movement of the rotating pin. When the trigger mechanism is activated, the gear adjustment transition sliding block overcomes the force of the gear adjustment transition spring, driving the pin top insert to disengage the rotating pin from the front reinforcing iron of the base, completing the rotation unlocking. After releasing the handle, the gear adjustment transition spring and the pin spring respectively push each component to reset, achieving automatic locking. This ensures smooth gear switching and positioning accuracy, and makes the rotation lock more stable and reliable, effectively avoiding jamming or loosening problems after long-term use.

[0023] 3. This invention features a main body disassembly mechanism with a movable and detachable locking hook. When the main body assembly needs to be disassembled, simply release the locking hook from the locking groove to separate the main body rod from the rotating seat, thereby achieving quick separation of the main body seat from the base. The operation is simple and quick, and the connection strength remains reliable even after long-term use. This avoids the defects of traditional bolts or complex buckle structures that are easy to loosen and difficult to disassemble, greatly facilitating users to clean, replace, or move the seat body.

[0024] 4. This invention incorporates a rotating pin and an iron groove. The rotating pin is U-shaped with arc-shaped surfaces on its left and right front ends. The inner side of the iron groove has a corresponding synchronous arc-shaped groove. When the rotating pin slides within the pin's movable groove, the arc-shaped surfaces and the synchronous arc-shaped groove form a smooth guiding fit, reducing frictional resistance and making the extension and retraction of the rotating pin smoother. The limiting rod and limiting pin, together with the pin spring, precisely limit and automatically reset the stroke of the rotating pin, improving the unlocking and locking response speed of the seat rotation mechanism and further enhancing ease of use and safety.

[0048] Example 1

[0049] The seat mechanism 100 includes a base 101 and a body assembly 102. The body assembly 102 includes a body seat 102a and a body frame 102b. The body seat 102a is fixed to the inner cavity of the body frame 102b.

[0050] One embodiment of this example is as follows: The triggering mechanism 200 includes a gear shift lever 201. The top of the gear shift lever 201 is slidably connected to the bottom of the seat 102a. Gear shift levers 202 are fixedly connected to the left and right sides of the back of the gear shift lever 201. A spring baffle 203 is fixedly connected to the left side of the gear shift lever 202. A return spring 204 is fixedly connected to the back of the spring baffle 203. The end of the return spring 204 away from the spring baffle 203 is fixedly connected to the seat 102a. The inner cavity of the gear shift lever 202 is movably connected to the gear shift lever 202. The gear lever 205 has a gear shift lever 202 passing through its left and right sides. A gear shift adapter bracket 206 is fixedly connected to the bottom of the main body seat 102a and to the inner side of the gear shift lever 202. A gear shift adapter sliding bracket 207 is fixedly connected to the bottom of the gear shift adapter bracket 206. A wire rope sleeve 208 is fixedly connected to the back end of the inner cavity of the gear shift adapter sliding bracket 207. A wire rope 209 is slidably connected to the inner cavity of the wire rope sleeve 208. The front end of the wire rope 209 passes through the wire rope sleeve 208 and is fixedly connected to the back end of the main body gear shift lever 201.

[0051] An inclined groove 202a is provided in the inner cavity of the gear shift lever 202 and at the position corresponding to the gear shift bar 205 of the main body. The gear shift bar 205 of the main body slides through the inclined groove 202a in cooperation with the gear shift lever 202.

[0052] The left and right sides of the inner cavity of the main seat 102a are provided with longitudinal moving grooves 102a-1, which correspond to the positions of the main body gear shift bar 205. The left and right sides of the main body gear shift bar 205 slide through the longitudinal moving grooves 102a-1.

[0053] A groove is provided at the bottom of the main seat 102a along the front-to-back direction. The top of the main gear shift handle 201 has a shape that matches the groove. The main gear shift handle 201 is embedded in the groove and can slide in a straight line along the groove, thereby ensuring that the main gear shift handle 201 moves smoothly during the pulling process. Gear shift levers 202 are fixedly connected to the left and right sides of the back end of the main gear shift handle 201. The gear shift levers 202 on both sides are symmetrically arranged and extend along the front-to-back direction, and are parallel to the main gear shift handle 201. They are fixedly connected to the back end of the main gear shift handle 201 by screws. A spring baffle 203 is fixedly connected to the left side of the single gear shift lever 202 on the left side. The spring baffle 203 is a plate-shaped component, which is integrally formed with the gear shift lever 202.

[0054] A return spring 204 is fixedly connected to the back end of the spring baffle 203. The return spring 204 is a cylindrical helical compression spring, and its axis is parallel to the gear shift lever 202. One end of the return spring 204 abuts against the rear end face of the spring baffle 203, and the other end is fixedly connected to the bottom of the inner cavity of the main body seat 102a through a spring seat. When the main body gear shift lever 201 is pulled forward, the gear shift lever 202 moves forward, the spring baffle 203 stretches the return spring 204, and stores elastic potential energy. After being released, the return spring 204 releases energy, pulling the spring baffle 203, the gear shift lever 202, and the main body gear shift lever 201 to return to their original positions. The inner cavity of the gear shift lever 202 is movably connected to the main body gear shift rod 205. Specifically, a through-beam is provided in the middle of the gear shift lever 202. The inclined groove 202a on the right side wall is composed of a front horizontal groove, a middle groove inclined to the right, and a rear horizontal groove. The main body gear shift rod 205 is a long cylindrical rod, with its two ends passing through the inclined grooves 202a of the left and right gear shift levers 202 respectively. The left and right ends of the main body gear shift rod 205 pass through the gear shift levers 202 and extend further into the longitudinal moving grooves 102a-1 opened on the left and right side walls of the inner cavity of the main body seat 102a. The longitudinal moving groove 102a-1 is a long strip-shaped through hole extending in the vertical direction. Its width forms a clearance fit with the diameter of the main body gear shift rod 205, allowing the main body gear shift rod 205 to slide up and down in the longitudinal moving groove 102a-1, while restricting its position in the front and rear directions. Due to the contour guiding effect of the inclined groove 202a;

[0055] A steel wire rope sleeve 208 is fixedly connected to the back end of the inner cavity of the gear shifting sliding bracket 207. The steel wire rope sleeve 208 is a steel sleeve. One end of the steel wire rope sleeve 208 is fixed to the rear end face of the gear shifting sliding bracket 207 through a clamping joint. The other end is bent along the inner wall of the base 101 and extends to the gear shifting handle 201 of the main body. The back end of the steel wire rope sleeve 208 passes through the back end of the gear shifting sliding bracket 207, so that the steel wire rope 209 can pass out from this end.

[0056] When the shift lever 202 moves back and forth, the shift lever 205 is forced to move along the trajectory of the inclined groove 202a, thereby producing vertical displacement. Specifically, when the shift lever 201 is pulled forward, the shift lever 202 moves forward, and the shift lever 205 is lifted upward under the guidance of the inclined groove section of the inclined groove 202a, thereby disengaging from the circular transverse slide groove of the lower gear slot 401. When the lever is released, the shift lever 202 moves backward under the action of the return spring 204, and the shift lever 205 is reset downward under the reverse guidance of the inclined groove 202a, and re-engages into the corresponding slide groove of the gear slot 401.

[0057] By setting a trigger mechanism 200, when the user pulls the main body gear shift lever 201 forward, the gear shift lever 202 moves forward synchronously. On one hand, it drives the main body gear shift rod 205 to lift upward under the constraint of the inclined groove 202a and the longitudinal moving groove 102a-1, so that the main body gear shift rod 205 completely disengages from the circular transverse sliding groove of the gear position groove 401, thereby unlocking the gear adjustment mechanism 400. At this time, the user can adjust the tilt angle of the main body seat 102a as needed. The pulling action of the main body gear shift lever 201 is synchronously transmitted to the seat rotation mechanism 500 through the steel wire rope 209 connected to it, driving the rotating pin 505 to disengage from the iron groove 101b, realizing rotational unlocking, so that the main body assembly 102 can rotate freely relative to the base 101. After releasing the main body gear shift lever 201, the return spring 204 drives all moving parts to return to their original position, and the main body gear shift rod 205 is released. When the new card is inserted into the corresponding gear position of the gear position slot 401, the rotating pin 505, after rotating 180° or 360°, is inserted into the corresponding iron groove 101b at the back end under the action of the pin spring 505c, or re-inserted into the iron groove 101b at the front end, realizing dual automatic locking of gear position and rotation. Thus, the trigger mechanism 200 successfully solves the technical problem of the existing child safety seats where gear position adjustment and rotation adjustment need to be operated separately, the steps are cumbersome, and the operation efficiency is low. It realizes the integrated operation of gear position adjustment and rotation unlocking through a single handle, which significantly improves the convenience and adjustment efficiency of users. At the same time, the cooperative design of the inclined groove 202a and the longitudinal moving groove 102a-1 ensures that the main body gear adjustment rod 205 is accurately guided and free from jamming during the up and down displacement process, extends the service life of the mechanism, and gives users a clear operating feel.

[0058] Example 2

[0059] Based on Embodiment 1, this embodiment takes into account that the disassembly of the main body assembly 102 and the base 101 in existing child safety seats usually requires the use of tools or the simultaneous operation of multiple independent locking structures, resulting in a cumbersome and time-consuming disassembly and assembly process. Furthermore, some detachable designs are prone to loosening or jamming after long-term use, affecting the safety of children riding in the seat. Therefore, this embodiment provides a main body disassembly mechanism 300, which includes a rotating seat 301. The rotating seat 301 is located at the bottom of the inner wall of the base 101 and can rotate relative to the base 101. The four corners of the top of the rotating seat 301 are provided with locking hooks 302. Locking grooves 303 are provided at the front and back ends of the top of the rotating seat 301, corresponding to the positions of the locking hooks 302. The front and back ends of the top of the rotating seat 301, corresponding to the positions of the locking grooves 303, are fixedly connected to the main body rod 304 by the locking hooks 302. The left and right sides of the surface of the main body rod 304, corresponding to the left and right sides of the rotating seat 301, are movably sleeved with the main body iron bracket 305. The surface of the main body iron bracket 305 is fixedly connected to the bottom of the inner cavity of the main body seat 102a by screws. The locking hook 302 is set as a movable and detachable structure. The locking hook 302, together with the main body rod 304 and the main body iron bracket 305, is used to install and remove the main body seat 102a.

[0060] The main body disassembly mechanism 300 includes a rotating seat 301, which is located at the bottom of the inner wall of the base 101. The bottom center of the rotating seat 301 is rotatably connected to the bottom of the inner wall of the base 101, allowing the rotating seat 301 to rotate smoothly relative to the base 101. Each of the four corners of the top of the rotating seat 301 has a locking hook 302, each consisting of a hook body and a connecting seat. The hook body has a downward-bent barb at its end. The connecting seat is fixed to the top surface of the rotating seat 301 by screws. Locking grooves 303 are provided at the front and rear ends of the top of the rotating seat 301, corresponding to the position of each locking hook 302. The locking grooves 303 are circular recesses, the depth of which matches the thickness of the barb of the locking hook 302. When the locking... When hook 302 is in the locked position, its barb part fits precisely into the corresponding locking groove 303, forming a vertical limit. The front and rear ends of the top of the rotating seat 301, corresponding to the positions of the locking grooves 303, are fixedly connected to the main body rod 304 by the hook 302. The main body rod 304 consists of two parallel round rods, each extending horizontally in the left-right direction. Its two ends are fixed to the rotating seat 301 by the connecting seats of the hook 302. The hook 302 has a semi-circular groove in which the main body rod 304 is embedded and locked, thereby securely installing the main body rod 304 on the rotating seat 301. The main body rod 304 is movably sleeved on the left and right sides of the surface of the main body rod 304, corresponding to the left and right sides of the rotating seat 301. The iron bracket 305 is a stamped metal plate with a slotted hole that fits the outer diameter of the main body rod 304, allowing it to slide freely along the axial direction of the main body rod 304. Each iron bracket 305 is fixedly connected to the bottom of the inner cavity of the main body seat 102a by screws. The upper end face of the iron bracket 305 has a threaded hole, and a countersunk hole is provided at the corresponding position on the bottom of the main body seat 102a. The two are locked together by screws, thus connecting the iron bracket 305 and the main body seat 102a as one unit. The locking hook 302 is a movable and detachable structure, which, together with the main body rod 304 and the iron bracket 305, secures the main body seat 102a. For installation and disassembly, during installation, place the main body seat 102a, which is fixed with the main body iron bracket 305, from top to bottom, align the round hole of the main body iron bracket 305 with the end of the main body rod 304 and insert it, then place the main body rod 304 in the locking groove 303. At this time, the locking hook 302 is engaged in the locking groove 303 to lock the main body rod 304, locking the main body iron bracket 305 and the main body seat 102a on the rotating seat 301, preventing them from sliding out. During disassembly, the user manually disengages the locking hook 302 from the locking groove 303, and then the main body rod 304, as well as the main body iron bracket 305 and the main body seat 102a connected to the main body rod 304, can be completely removed. The entire disassembly and assembly process does not require any tools and can be completed with one hand.

[0061] By setting up the main body disassembly mechanism 300, the main body component 102 and the base 101 can be quickly and tool-free installed and disassembled. The sliding engagement structure of the locking hook 302, locking groove 303, main body rod 304 and main body iron bracket 305 allows the user to complete the disassembly and assembly with just one pulling action. Compared with the operation method that requires bolts or multiple buckles in the existing technology, the operation process is greatly simplified, saving time and effort, while ensuring the stability after installation. Even after long-term use, it will not loosen due to vibration.

[0062] Example 3

[0063] In this embodiment, a gear adjustment mechanism 400 is provided. The gear adjustment mechanism 400 includes a gear groove 401. The top of the gear groove 401 is provided with a circular transverse sliding groove for multiple gears in conjunction with the gear adjustment bar 205 of the main body. The gear groove 401 is located at the bottom of the inner wall of the rotating seat 301. The top of the surface of the gear groove 401 is in contact with the surface of the gear adjustment bar 205 of the main body. The front end and back end of the inner cavity of the main body iron bracket 305 and the corresponding range of motion of the main body bar 304 are provided with a sliding groove 402 of the main body iron bracket. The main body seat 102a and the main body iron bracket 305 slide on the surface of the main body bar 304 through the sliding groove 402 of the main body iron bracket.

[0064] The gear adjustment mechanism 400 includes a gear slot 401, which extends along the front-to-back direction. Its bottom is fixedly located at the bottom of the inner wall of the rotating seat 301. The upper surface of the gear slot 401 is provided with multiple circular transverse sliding grooves for different gear positions, which are matched with the gear adjustment rod 205. Multiple arc-shaped grooves are sequentially machined along the length of the upper surface of the gear slot 401. The cross-section of each groove is semi-circular and matches the outer diameter of the gear adjustment rod 205, so that the gear adjustment rod 205 can smoothly fall into or out of the groove. In the locked state, the lower half of the gear adjustment rod 205 is embedded in one of the circular transverse sliding grooves, and the cylindrical surfaces of the two form a close contact, thereby restricting the front-to-back movement of the main seat 102a relative to the rotating seat 301. In the unlocked state, that is, when the gear adjustment rod 205 is lifted upward by the trigger mechanism 200, the gear adjustment rod 205 is disengaged from the gear slot 401, allowing the main seat 102a to slide freely to change gears.

[0065] The front and back ends of the inner cavity of the main body iron bracket 305, corresponding to the range of motion of the main body rod 304, are provided with sliding grooves 402. Each main body iron bracket 305 has an inverted arc-shaped structure, and a long arc-shaped hole, i.e., the sliding groove 402, is provided on the front and back side walls of its inner cavity, allowing the main body rod 304 to pass through the groove and slide relative to each other. The length of the groove determines the sliding stroke of the main body seat 102a relative to the rotating seat 301, corresponding to the gear adjustment range. The main body seat 102a and the main body iron bracket 305 are connected by the sliding grooves of the main body iron bracket. 402 slides on the surface of the main body rod 304. Since the main body rod 304 is fixedly installed on the rotating seat 301 and remains stationary, while the main body iron bracket 305 is fixedly connected to the main body seat 102a by screws, when the user pushes or pulls the main body seat 102a, the main body iron bracket 305 slides back and forth along the main body rod 304 by means of the main body iron bracket sliding groove 402 on it, thereby driving the entire main body seat 102a to slide back and forth relative to the rotating seat 301. During this process, the main body gear shifting rod 205 is lifted or lowered under the drive of the trigger mechanism 200 to realize gear switching and locking.

[0066] By setting up the gear adjustment mechanism 400, the tilt angle adjustment function of the main seat 102a relative to the base 101 is realized in multiple positions, ensuring the smoothness during the adjustment process and the stability after locking. The multiple circular horizontal sliding grooves on the gear slot 401 cooperate with the main body gear adjustment rod 205 to form a stepped positioning structure. Each gear corresponds to a precise tilt angle, and the user can accurately feel the gear position by hand. At the same time, the sliding groove 402 of the main body iron bracket and the sliding cooperation of the main body rod 304 provide a precise guide track for angle adjustment, avoiding the main seat 102a from swaying or shaking from side to side during the adjustment process. When the main body gear shift lever 205 falls into the circular transverse slide groove under the action of the return spring 204, the arc contour of the slide groove forms a surface contact with the cylindrical surface of the lever, which can effectively withstand the front and rear impact force generated during vehicle collision and prevent accidental disengagement. In addition, the gear position groove 401 is set at the bottom of the inner wall of the rotating seat 301 and is integrated with the rotating seat 301, which simplifies the number of parts and improves the structural rigidity. Thus, this embodiment solves the technical problems of easy jamming, unclear gear position, and insufficient locking strength of the gear adjustment mechanism in the prior art, and achieves the beneficial effects of smooth adjustment feel, accurate gear positioning, stable and reliable locking, and compact structure.

[0070] The inner cavity of the rotating pin 505 is movably connected to a limiting rod 505a. The front end of the limiting rod 505a passes through the front end of the rotating pin 505 and is fixedly connected to the back end of the pin movable slot plate 501.

A pin spring 505c is fixedly connected to the surface of the limiting pin 505b and the surface of the limiting rod 505a. The front end of the pin spring 505c is fixedly connected to the back end of the rotating pin 505.

[0071] A front reinforcing iron 101a is provided in the inner cavity of the base 101 and at the position corresponding to the rotating pin 505. An iron groove 101b is provided in the inner cavity of the front reinforcing iron 101a and at the position corresponding to the rotating pin 505. An arc-shaped surface 101c is provided on the left and right sides of the front end of the rotating pin 505. A synchronous arc-shaped groove 101d is provided on the inner side of the iron groove 101b and at the position corresponding to the arc-shaped surface 101c.

[0072] The base front reinforcing iron 101a is made of steel plate and has two parts, which are fixedly installed on the front end and rear end of the inner wall of the base 101 respectively. Each base front reinforcing iron 101a is fastened to the side wall of the base 101 by bolts. The bottom of the front end of the rotating seat 301 and the position corresponding to the base front reinforcing iron 101a are fixedly connected to the pin movable slot plate 501. The front end of the pin movable slot plate 501 contacts the rear end of the base front reinforcing iron 101a. The pin movable slot plate 501 is fixed to the rotating seat 301 by welding and rotates together with the rotating seat 301. The front end of the pin movable slot plate 501 contacts the back end of the base front reinforcing iron 101a so that the rotating pin 505 can be smoothly inserted or removed.

[0073] A gear shift adapter bracket 206 is fixedly connected to the bottom of the main seat 102a and the inner side of the gear shift lever 202. The gear shift adapter bracket 206 is a metal bracket, and its top is fastened to the bottom surface of the main seat 102a by screws. A gear shift adapter sliding bracket 207 is fixedly connected to the bottom of the gear shift adapter bracket 206 and is bolted together. The gear shift adapter sliding bracket 207 is a frame-shaped component that extends in the front-back direction. Its bottom is fixedly connected to the top of the pin movable slot plate 501. A round hole 502 is opened in the inner cavity of the gear shift adapter sliding bracket 207. The axis of the round hole 502 extends horizontally in the left-right direction. The gear shift adapter sliding bracket 207 is sleeved on the surface of the main rod 304 through the round hole 502 to form a clearance fit.

[0074] The inner cavity of the gear shifting sliding bracket 207 and the front end of the corresponding wire rope sleeve 208 are slidably connected to a gear shifting sliding block 503. The gear shifting sliding block 503 is a rectangular metal slider, and its outer contour forms a sliding fit with the inner cavity of the gear shifting sliding bracket 207, allowing it to move back and forth only in the front-to-back direction. The front and rear faces of the gear shifting sliding block 503 are both flat, and its interior has a hole for accommodating the top insert 506 of the pin. The back end of the gear shifting sliding block 503 is fixedly connected to a gear shifting adapter. Spring 504, the gear shifting spring 504 is a cylindrical helical compression spring with its axis along the front-rear direction. The back end of the gear shifting spring 504 is fixedly connected to the front end of the inner wall of the gear shifting sliding bracket 207. The rear end of the gear shifting spring 504 abuts against the spring seat on the front inner wall of the gear shifting sliding bracket 207, while the front end abuts against the rear end face of the gear shifting sliding block 503. Under normal conditions, the gear shifting spring 504 pushes the gear shifting sliding block 503 forward, keeping it in the initial position at the front end.

[0075] A wire rope 209 is slidably connected to the inner cavity of the wire rope sleeve 208. The wire rope 209 is made of multiple strands of fine steel wire twisted together, possessing high tensile strength and low elongation. The wire rope 209 is threaded through the wire rope sleeve 208 and can slide freely within it. Due to the constraint of the wire rope sleeve 208, the bending trajectory of the wire rope 209 is limited. The front end of the wire rope 209 is fixedly connected to the back end of the shifting transition sliding block 503. The end of the wire rope 209 away from the shifting transition sliding block 503 is connected to the back end of the main body shifting handle 201 by a ball joint engagement. When the main body shifting handle 201 is pulled forward, the wire rope 209 is pulled accordingly, thereby pulling the shifting transition sliding block 503 to move backward, compressing the shifting transition spring 504. A rotating pin 505 is slidably connected to the inner cavity of the pin movable slot plate 501. The movable slot plate 501 of the pin has a rectangular guide hole extending in the front-to-back direction. The main body of the rotating pin 505 is embedded in the guide hole and can only slide in the front-to-back direction. The rotating pin 505 is set as a U-shaped block with two parallel pin arms extending forward from the front end. The overall shape is similar to a U-shape. The U-shaped design makes the rotating pin 505 have better guiding stability and bending resistance when sliding. The bottom of the front end of the rotating pin 505, that is, the lower edge of the front end of the bottom pin arm, extends to the front end of the front reinforcing iron 101a of the base. When the rotating pin 505 is in the locked position, the pin arm at the bottom front end passes through the front end face of the movable slot plate 501 of the pin and further enters the iron groove 101b opened on the front reinforcing iron 101a of the base, thereby restricting the rotation of the rotating seat 301 relative to the base 101.

[0076] A pin top insert 506 is fixedly connected to the top of the rotating pin 505. The pin top insert 506 is a vertically upward rectangular plate, the lower end of which is fixed to the upper surface of the rotating pin 505 by welding. The top of the pin top insert 506 extends through the inner cavity of the shifting transition sliding block 503. The shifting transition sliding block 503 has a downward-facing insertion hole at its lower part. The upper end of the pin top insert 506 is inserted into the insertion hole, and the two form a sliding fit. When the shifting transition sliding block 503 moves back and forth, it will drive the rotating pin 505 to move back and forth synchronously through the pin top insert 506. When the shifting transition sliding block 503 moves backward, it pulls the pin top insert 506 and the rotating pin 505 to exit the front reinforcing iron 101a of the base, realizing rotational unlocking. When the shifting transition sliding block 503 moves forward, it pushes the rotating pin 505 forward and inserts it into the front reinforcing iron 101a of the base, realizing rotational locking.

[0077] The wire rope sleeve 208 is designed to adapt to the shape of the wire rope 209 pulled by the main body gear shift handle 201, and the bottom bend is parallel to the gear shift transition sliding block 503. The wire rope sleeve 208 starts from the main body gear shift handle 201 and bends along the contour of the bottom of the main body seat 102a and the inner wall of the base 101, forming a smooth arc transition at its bottom bend. The tangent at this bend is parallel to the sliding direction of the gear shift transition sliding block 503, thereby ensuring that the friction force on the wire rope 209 at this bend section is minimized and the force loss is minimized when pulling. The wire rope sleeve 208 moves in conjunction with the wire rope 209, playing a guiding and protective role.

[0078] A limiting rod 505a is movably connected to the inner cavity of the rotating pin 505. The limiting rod 505a is a slender metal rod that penetrates the interior of the rotating pin 505 in the front-back direction. After the front end of the limiting rod 505a passes through the front end of the rotating pin 505, it extends further forward and is fixedly connected to the back end of the pin movable slot plate 501. Therefore, the limiting rod 505a is stationary relative to the pin movable slot plate 501. The back end of the limiting rod 505a passes through the back end of the rotating pin 505 and is fixedly connected to the limiting pin 505b by threads. The limiting pin 505b is a round-headed screw with a diameter larger than that of the limiting rod 505a. It is screwed onto the rear end of the limiting rod 505a and acts as a limiting stop for the rotating pin 505 to slide backward, preventing it from coming off the limiting rod 505a. A pin spring 505c is fixedly connected to the surface of the nail 505b and the corresponding surface of the limiting rod 505a. The pin spring 505c is a cylindrical helical compression spring, which is sleeved on the limiting rod 505a. The front end of the pin spring 505c is fixedly connected to the back end of the rotating pin 505, and the rear end abuts against the front end surface of the limiting nail 505b. Under normal conditions, the pin spring 505c is in a pre-compressed state, and its elastic force pushes the rotating pin 505 forward, keeping it in the tendency to be inserted into the iron groove 101b. When the rotating pin 505 is pulled backward by the shifting sliding block 503, the pin spring 505c is further compressed and stores elastic potential energy. When the pulling force is removed, the pin spring 505c releases energy and pushes the rotating pin 505 to automatically return to its original position.

[0079] A groove 101b is provided at the front end of the base front reinforcing iron 101a and at the position corresponding to the rotating pin 505. The groove 101b is a rectangular through hole that matches the shape of the pin arm of the rotating pin 505. Correspondingly, arc surfaces 101c are provided on the left and right sides of the front end of the rotating pin 505. A rounded chamfer is machined on the edge of the front end face of the bottom pin arm to form the arc surface 101c. A synchronous arc groove 101d is provided on the inner side of the groove 101b and at the position corresponding to the arc surface 101c. The synchronous arc groove 101d is a concave arc surface that matches the arc surface 101c. When the rotating pin 505 is inserted into the groove 101b, the arc surface 101c and the synchronous arc groove 101d form a close contact, which plays a guiding role and makes the insertion process smoother.

[0080] By setting the seat rotation mechanism 500, the axial rotation adjustment and automatic locking functions of the main body assembly 102 relative to the base 101 are realized, and it is linked with the trigger mechanism 200 to achieve the beneficial effect of one-button synchronous unlocking. When the user pulls the main body gear shift handle 201 forward, the steel wire rope 209 is pulled, which drives the gear shift transition sliding block 503 to move backward against the elastic force of the gear shift transition spring 504. The gear shift transition sliding block 503 drives the rotating pin 505 to move backward synchronously through the pin top insert 506, so that the two pin arms at the front end of the rotating pin 505 completely disengage from the iron groove 101b, thereby releasing the lock between the rotating seat 301 and the base 101. At this time, the user can freely rotate the main body assembly 102 to the desired angle. After releasing the main body gear shift handle 201, the gear shift transition spring 504 pushes the gear shift transition sliding block 505. 03. Reset forward, and at the same time, the pin spring 505c also pushes the rotating pin 505 forward, so that the rotating pin 505 is re-inserted into the iron groove 101b. If the rotation angle is just enough to align the pin arm with the iron groove 101b, the pin is fully inserted and automatically locked. If it is not aligned, the front end of the rotating pin 505 will abut against the inner side of the front reinforcing iron 101a of the base and be in a compressed state. At this time, the user slightly rotates the main body assembly 102. When it is rotated to the aligned position, the pin spring 505c will push the rotating pin 505 to automatically spring into the groove. This solves the technical problems in the prior art that rotation adjustment and gear adjustment need to be operated separately, cannot be automatically locked after rotation, or have no feedback when locked. It achieves the beneficial effects of rotation unlocking and gear unlocking linkage, automatic locking after rotation and clear sound feedback, effortless operation, and safety and reliability.

[0081] Working principle: When the user needs to adjust the seat posture, he pulls the main body gear shift handle 201 forward. The main body gear shift handle 201 slides forward, driving the gear shift levers 202 on both sides to move forward simultaneously. The inclined groove 202a on the gear shift lever 202 forces the main body gear shift rod 205 to move along the trajectory of the inclined groove 202a. The main body gear shift rod 205 slides under the guidance of the front horizontal groove, and the gear position is unlocked by the gear position groove 401. At this time, the return spring 204 is further stretched and stores elastic potential energy.

[0082] As the gear shift lever 201 is pulled forward, the steel wire rope 209, which is connected to its back end by a ball joint, is pulled. The steel wire rope 209 slides inside the steel wire rope sleeve 208, and its front end pulls the gear shift transition sliding block 503 to move backward against the elastic force of the gear shift transition spring 504. The gear shift transition sliding block 503 drives the rotating pin 505 to move backward synchronously through the pin top insert 506, so that the pin arm at the front end of the rotating pin 505 completely disengages from the iron groove 101b, realizing rotational unlocking. At this time, the pin spring 505c is further compressed, storing elastic potential energy.

[0083] The user pushes or pulls the main seat 102a forward or backward. The main body iron bracket 305 slides back and forth along the surface of the main body rod 304 through the main body iron bracket sliding groove 402, causing the entire main body seat 102a to move back and forth relative to the rotating seat 301. Since the gear position groove 401 is fixedly set at the bottom of the inner wall of the rotating seat 301, and the main body gear adjustment rod 205 has been lifted up and disengaged from the gear position groove 401, the main body seat 102a can smoothly slide to different tilt angle positions. The multiple circular horizontal grooves on the gear position groove 401 correspond to different tilt angles in sequence, and the user can select the appropriate gear as needed.

[0084] The user directly rotates the main seat 102a, and the rotating seat 301 rotates with the main seat 102a relative to the base 101. Since the rotating pin 505 has been removed from the iron groove 101b, the rotating seat 301 can rotate freely to the desired orientation. The rotating shaft at the bottom of the rotating seat 301 ensures that the rotation process is smooth and stable.

[0085] After the gear shift lever 201 is released, the return spring 204 releases its stored elastic potential energy, pulling the spring baffle 203, the gear shift lever 202, and the gear shift lever 201 back to their original positions. When the gear shift lever 202 moves backward, the inclined groove 202a guides the gear shift bar 205 to move downward along the inclined groove. Under the constraint of the longitudinal moving groove 102a-1, the gear shift bar 205 falls vertically and re-locks into the corresponding circular transverse sliding groove in the gear position groove 401. Since the arc contour of the sliding groove forms a surface contact with the cylindrical surface of the gear shift bar 205, it can effectively withstand the impact force in the front and rear directions after locking, preventing accidental disengagement.

[0086] After the gear shift lever 201 is released, the gear shift transition spring 504 pushes the gear shift transition sliding block 503 to return to its original position. At the same time, the pin spring 505c releases its elastic potential energy, pushing the rotating pin 505 to move forward. The pin arm at the front end of the rotating pin 505 extends forward under the action of the pin spring 505c.

[0087] When it is necessary to remove the main body assembly 102 from the base 101, control the locking hook 302 to disengage the barb part of the locking hook 302 from the locking groove 303, thereby releasing the lock on the main body rod 304. Then, pull the main body seat 102a outward, and the main body iron bracket 305 slides outward along the main body rod 304 until it is completely separated from the main body rod 304. The main body seat 102a and the main body iron bracket 305 can then be removed from the base 101 together. The entire disassembly process does not require any tools and can be completed with one hand.
