Description

Technical Field

[0001] This utility model relates to the field of vehicle seat adjustment technology, specifically a torsion locking slide rail structure. Background Technology

[0002] As a core functional component of the seat system, the car seat rail is mainly used to adjust the fore-and-aft position of the seat. It usually consists of a lower rail fixed to the vehicle body floor and an upper rail connected to the seat frame. The two are locked together by a locking mechanism to achieve relative fixation or sliding adjustment. Traditional rail locking mechanisms are mainly divided into two types: mechanical control and motor control.

[0003] However, while motor-controlled slide rail structures can achieve automated adjustment, they are complex in structure, have high manufacturing costs, and rely on the stability of electronic components. They are prone to failure in harsh environments and are difficult to maintain. On the other hand, existing mechanically controlled slide rail locking structures have many parts, resulting in a large locking mechanism that occupies the installation space under the seat and affects the arrangement of other functional components.

[0004] Therefore, it is necessary to design a torsion locking slide rail structure that is simple in structure and low in manufacturing cost. Utility Model Content

[0005] The purpose of this invention is to provide a torsion locking slide rail structure to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a torsion locking slide rail structure, including an upper slide rail and a lower slide rail, wherein the upper slide rail and the lower slide rail are slidably connected relative to each other, a front fixed frame and a rear fixed frame are fixedly installed on one side of the upper slide rail, the front fixed frame has a positioning hole, one side of the rear fixed frame is welded to the upper slide rail, the side of the rear fixed frame away from the upper slide rail is bent downward to form at least two positioning sleeves, a rotating shaft is connected through the positioning hole and the positioning sleeve, a locking piece is connected between the two positioning sleeves on both sides of the rotating shaft, a slot is opened at one end of the rotating shaft near the rear fixed frame, and a torsion spring is sleeved at one end of the rotating shaft near the rear fixed frame, one end of the torsion spring is fixed inside the slot, and the other end of the torsion spring is fixed on the upper slide rail, a plurality of toothed grooves are equidistantly opened at the bottom of the lower slide rail, and at least two protruding teeth that mesh with the toothed grooves are opened on the locking piece.

[0007] According to the above technical solution, a handle is connected to the side of the rotating shaft near the front fixed frame.

[0008] According to the above technical solution, the top surface of the upper slide rail is provided with mounting holes at both ends for connection with the outside.

[0009] According to the above technical solution, the bottom surfaces of the sliding rail are connected to fixing columns for fixing to the external structure.

[0010] According to the above technical solution, the rear fixing bracket has a groove for accommodating the locking piece at the position of the locking piece.

[0011] According to the above technical solution, the convex tooth is fitted with an anti-slip sleeve.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] (1) By setting a rotating shaft, locking plate, torsion spring and toothed groove on the lower slide rail, when it is necessary to adjust the position of the upper slide rail relative to the lower slide rail, the operating handle drives the rotating shaft to rotate, the rotating shaft stretches the torsion spring, so that the protruding teeth on the locking plate separate from the toothed groove of the lower slide rail. At this time, the upper slide rail can slide freely. After adjusting to the appropriate position, the handle is released, the torsion spring returns to its deformation, drives the rotating shaft to rotate in the opposite direction, so that the protruding teeth on the locking plate re-mesh with the toothed groove, thus achieving locking. Compared with traditional motor control and complex mechanical control, the structure is simple, the operation is convenient, and the cost is relatively low.

[0014] (2) By setting a positioning sleeve and a groove, the positioning sleeve provides good support and positioning for the rotating shaft, ensuring the stability of the rotating shaft. The groove provides installation space for the locking plate, realizing the linkage between the locking plate, the rotating shaft and the torsion spring, making the overall structure more compact and reducing manufacturing costs and assembly difficulty.

[0019] To enable those skilled in the art to better understand the present invention, the solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] This utility model provides a technical solution: a torsion locking slide rail structure, including an upper slide rail 10 and a lower slide rail 20, the upper slide rail 10 and the lower slide rail 20 being slidably connected relative to each other. A front fixing bracket 11 and a rear fixing bracket 12 are fixedly installed on one side of the upper slide rail 10. The front fixing bracket 11 has a positioning hole 111. One side of the rear fixing bracket 12 is welded to the upper slide rail 10. The side of the rear fixing bracket 12 away from the upper slide rail 10 is bent downward to form at least two positioning sleeves 13. A torsion bar is connected through the positioning hole 111 and the positioning sleeve 13. A rotating shaft 14 is connected to a locking piece 30 between the two positioning sleeves 13. A slot 141 is provided at one end of the rotating shaft 14 near the rear fixing frame 12, and a torsion spring 142 is sleeved at the other end of the rotating shaft 14 near the rear fixing frame 12. One end of the torsion spring 142 is fixed inside the slot 141, and the other end of the torsion spring 142 is fixed on the upper slide rail 10. A plurality of toothed grooves 21 are provided at equal intervals at the bottom of the lower slide rail 20. At least two protruding teeth 31 that mesh with the toothed grooves 21 are provided on the locking piece 30.

[0021] With this technical solution, when it is necessary to adjust the position of the upper slide rail 10 relative to the lower slide rail 20, the rotating shaft 14 is driven to rotate. The rotating shaft 14 stretches the torsion spring 142, causing the protruding teeth 31 on the locking plate 30 to separate from the tooth groove 21 of the lower slide rail 20. At this time, the upper slide rail 10 can slide freely. After adjusting to the appropriate position, the rotating shaft 14 is released, the torsion spring 142 returns to its deformation, and the rotating shaft 14 rotates in the opposite direction, so that the protruding teeth 31 on the locking plate 30 re-engages with the tooth groove 21, thereby achieving locking. Compared with traditional motor control and complex mechanical control, the structure is simple, the operation is convenient, and the cost is relatively low.

[0022] Furthermore, a handle 143 is connected to the side of the rotating shaft 14 near the front fixing frame 11;

[0023] With this technical solution, the operator can easily drive the rotating shaft 14 to rotate through the operating handle 143, thereby realizing the separation and engagement of the protruding teeth 31 and the tooth groove 21 on the locking plate 30, which improves the convenience of operation.

[0024] Furthermore, mounting holes 15 for external connection are provided at both ends of the top surface of the upper slide rail 10;

[0025] This technical solution allows the upper slide rail 10 to be connected to the seat via the mounting hole 15, facilitating the application of the entire slide rail structure.

[0026] Furthermore, the bottom ends of the lower rail 20 are connected to fixing posts 22 for fixing to the external structure;

[0027] This technical solution allows the sliding rail 20 to be fixed to the external support structure using the fixed column 22, ensuring the stability of the sliding rail structure.

[0028] Furthermore, the rear fixing bracket 12 has a groove 121 for accommodating the locking piece 30 at the position of the locking piece 30;

[0029] This technical solution provides mounting space for the locking piece 30 through the groove 121, making the overall structure more compact.

[0030] Furthermore, an anti-slip sleeve is fitted onto the convex tooth 31;

[0031] This technical solution increases the friction between the protruding teeth 31 and the tooth groove 21, making the engagement between the protruding teeth 31 and the tooth groove 21 more secure and enhancing the stability of locking.

[0032] Working principle: When it is necessary to adjust the position of the upper slide rail 10 relative to the lower slide rail 20, the operator holds the handle 143 and applies external force to drive the rotating shaft 14 to rotate. When the rotating shaft 14 rotates, the torsion spring 142 at the end will deform, and at the same time, the locking piece 30 connected to the rotating shaft 14 will move longitudinally, so that the protruding teeth 31 on the locking piece 30 will separate from the tooth groove 21 at the bottom of the lower slide rail 20. At this time, the upper slide rail 10 can slide automatically relative to the lower slide rail 20 to achieve the unlocked state.

[0033] When adjusted to the appropriate position, the operator releases the handle 143, the torsion spring 142 returns to its original deformation, and generates a reverse force to drive the rotating shaft 14 to rotate in the opposite direction, thereby causing the locking plate 30 to rotate in the opposite direction. The protruding teeth 31 on the locking plate 30 re-engage with the tooth groove 21 of the lower slide rail 20, locking the upper slide rail 10 and the lower slide rail 20, thus completing the locking operation.
