Description

Technical Field

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

[0002] In automotive seat systems, the slide rail mechanism is a core adjustment component, playing a crucial role in the safety locking function of adjusting the seat's fore-and-aft position. Traditional slide rail structures typically employ a double-rail design, with the lower slide rail fixedly connected to the vehicle floor and the upper slide rail rigidly connected to the seat frame. The two are adjusted to be relatively fixed or slidably through a specific locking mechanism.

[0003] Currently, the commonly used slide rail locking structures are mainly divided into two types: electric and manual. Among them, the electric structure achieves automatic adjustment through a motor and transmission mechanism. Although it improves the convenience of operation, the manufacturing cost is high, making it difficult to popularize.

[0004] However, while existing manual structures simplify certain mechanical structures, they still require high precision in the machining of parts, and the manufacturing and installation process is cumbersome, so the structure is still not streamlined enough.

[0005] Therefore, it is necessary to design a rotary locking slide rail structure that is simpler in structure and more convenient in locking and unlocking operations. Utility Model Content

[0006] The purpose of this invention is to provide a rotary locking slide rail structure to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rotary 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 rotating plate is movably riveted to the top surface of the upper slide rail, and at least two mounting holes are provided on the side of the rotating plate away from the riveting end, wherein a handle is installed in the mounting holes by bolts, a spring hanging hole is provided on the side of the rotating plate near the handle, a hook groove is provided on one side of the upper slide rail, a spring for providing a restoring force is connected between the spring hanging hole and the hook groove, an L-shaped locking piece is provided on the rotating plate, a locking block is provided at the bottom of the L-shaped locking piece, and a plurality of locking grooves are equidistantly provided on one side of the lower slide rail, wherein the locking block can be matched and inserted into the locking groove to achieve locking.

[0008] According to the above technical solution, the rotating plate has a linkage hole on the side near the spring hanging hole, and at least two linkage seats are provided on the side away from the spring hanging hole. The rotating plate, the mounting hole, the spring hanging hole, the L-shaped locking piece, the locking block, the linkage hole and the linkage seat are integrally formed by stamping.

[0009] According to the above technical solution, the linkage hole and the linkage seat can be connected to the subrail on the opposite side by a connecting rod, which can optionally realize single-sided locking or double-sided linkage locking.

[0010] According to the above technical solution, mounting slots are provided on both sides of the top surface of the upper slide rail.

[0011] According to the above technical solution, the bottom surface of the lower slide rail is provided with fixing holes on both sides, and the lower slide rail is provided with a number of connecting holes at equal intervals between the fixing holes on both sides.

[0012] According to the above technical solution, the end of the handle away from the rotating plate is covered with a glove.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] (1) By setting a rotating plate, spring, L-shaped locking piece and locking groove, under normal conditions, the locking block at the bottom of the L-shaped locking piece is inserted into the locking groove of the lower slide rail to lock the upper slide rail and the lower slide rail. When the position needs to be adjusted, pull the handle, the rotating plate rotates around the riveted end, the spring is stretched, the locking block is disengaged from the locking groove, and the upper slide rail can slide relative to the lower slide rail. After adjusting to the appropriate position, release the handle, the spring's restoring force makes the rotating plate rotate back to its original position, and the locking block is inserted into the locking groove again to complete the locking. This structure is simple to operate and has low production cost, effectively solving the problems of complex structure, inconvenient operation and high cost of traditional slide rails.

[0015] (2) By setting linkage holes and linkage seats, the auxiliary rail on the opposite side can be connected by a connecting rod. Single-sided locking or double-sided linkage locking can be selected according to actual needs. Double-sided linkage locking can lock and unlock the slide rail and the auxiliary rail at the same time. Meanwhile, the rotating plate is stamped as an integral part of the mounting hole, spring hanging hole, L-shaped locking piece, locking block, linkage hole and linkage seat, which ensures the integrity and strength of the structure, reduces the number of parts and assembly process, and reduces production and maintenance costs.

[0020] 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.

[0021] This utility model provides a technical solution: a rotary 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 are slidably connected, a rotating plate 11 is movably riveted to the top surface of the upper slide rail 10, at least two mounting holes 111 are opened on the side of the rotating plate 11 away from the riveting end, a handle 30 is installed in the mounting holes 111 by bolts, a spring hanging hole 112 is opened on the side of the rotating plate 11 near the handle 30, a hook groove 12 is opened on one side of the upper slide rail 10, a spring 40 for providing a restoring force is connected between the spring hanging hole 112 and the hook groove 12, an L-shaped locking piece 113 is provided on the rotating plate 11, a locking block 114 is provided at the bottom of the L-shaped locking piece 113, a plurality of locking grooves 21 are equidistantly opened on one side of the lower slide rail 20, and the locking block 114 can be matched and inserted into the locking groove 21 to achieve locking.

[0022] This technical solution utilizes the cooperation of the rotating plate 11, spring 40, L-shaped locking piece 113 and the locking groove 21 of the lower slide rail 20 to simplify the complex mechanical structure of the traditional slide rail into simple rotation, elastic reset and locking actions. It achieves stable locking and convenient unlocking at low cost. During operation, only the handle 30 needs to be pulled to complete the slide rail position adjustment, reducing the difficulty of use and production cost.

[0023] Furthermore, the rotating plate 11 has at least two linkage holes 115 on the side near the spring hanging hole 112, and a linkage seat 116 is provided on the side away from the spring hanging hole 112. The rotating plate 11, the mounting hole 111, the spring hanging hole 112, the L-shaped locking piece 113, the locking block 114, the linkage hole 115 and the linkage seat 116 are integrally formed by stamping.

[0024] This technical solution reduces the number of parts assembly steps, lowers assembly errors, and improves the overall strength and stability of the structure through the one-piece molding process. At the same time, the pre-opening design of the linkage hole 115 and the linkage seat 116 provides an interface for the expansion of the slide rail function.

[0025] Furthermore, the linkage hole 115 and the linkage seat 116 can be connected to the subrail on the opposite side via a connecting rod, which can optionally achieve single-sided locking or double-sided linkage locking.

[0026] This technical solution connects the linkage hole 115 and the linkage seat 116 via a connecting rod, which can synchronously control the engagement and disengagement of the locking block 114 and the locking groove 21 on both sides of the slide rail, thereby achieving synchronous locking and unlocking on both sides.

[0027] Furthermore, mounting slots 13 are provided on both sides of the top surface of the upper slide rail 10;

[0028] This technical solution facilitates the connection between the upper slide rail 10 and the seat by installing the slot 13, and is compatible with various connector installation methods.

[0029] Furthermore, fixing holes 22 are provided on both sides of the bottom surface of the lower slide rail 20, and several connecting holes 23 are provided at equal intervals between the fixing holes 22 on both sides of the lower slide rail 20.

[0030] Through this technical solution, the fixing holes 22 are used for the stable installation of the lower slide rail 20 and the vehicle floor, ensuring the basic support of the slide rail, and the equidistantly distributed connecting holes 23 connect auxiliary support components to enhance the load-bearing capacity of the lower slide rail 20.

[0031] Furthermore, the end of the handle 30 away from the rotating plate 11 is covered with a handle glove 301;

[0032] This technical solution increases the friction between the hand and the handle 30 by increasing the glove 301, thereby improving operating comfort.

[0033] 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 pulls the handle 30. The handle 30 drives the rotating plate 11 to rotate around the riveting joint. At this time, the spring 40 is stretched, and the distance between the spring hanging hole 112 and the hook groove 12 increases. As the rotating plate 11 rotates, the L-shaped locking piece 113 moves synchronously, and the bottom locking block 114 disengages from the locking groove 21 of the lower slide rail 20. The upper slide rail 10 loses its locking restriction and can slide freely. After adjusting to the appropriate position, the operator releases the handle 30, and the spring 40 restores its deformation and generates a reset pulling force, pulling the rotating plate 11 back to its original position. The locking block 114 is reinserted into the corresponding locking groove 21, thus achieving the locking and fixing of the upper slide rail 10 and the lower slide rail 20.

[0034] If the double-sided linkage locking mode is enabled, the linkage hole 115 and the linkage seat 116 are connected by a linkage rod, which can synchronously control the engagement and disengagement of the locking block 114 and the locking groove 21 on both sides of the slide rail, so as to realize the synchronous locking and unlocking on both sides.
