Abstract
Description
Technical Field
[0001] This utility model belongs to the field of seat technology, and in particular relates to a seat slide rail reinforcement structure. Background Technology
[0002] Car seat slide rails are subjected to extremely high forces during a vehicle collision, and the upper and lower rails may separate. Typically, the upper rail is reinforced at the ends to prevent this separation.
[0003] Currently, the most common reinforcement structure involves riveting and welding two reinforcing hooks to the upper rail body. This structure increases the riveting process and requires ensuring that there are no abnormal noises between the two reinforcing hooks, rivets, and the rail body. Both of these factors increase the cost of the slide rail.
[0004] Other reinforcing structures include one-piece cast nuts or cast reinforcing structures. Since the cast structures are larger and solid, the cost of the castings is higher, and the weight of the slide rail is also increased. Summary of the Invention
[0005] The purpose of this invention is to provide a slide rail reinforcement structure that suppresses the separation between the upper rail end and the lower rail, reduces sliding noise, and has low production cost.
[0006] The purpose of this utility model is to solve the following problem:
[0007] A sliding rail reinforcement structure includes a lower rail with an inverted "T"-shaped groove and an upper rail sliding on the "T"-shaped groove. The lower rail has short arms extending inward from the upper ends of the two side walls of the "U"-shaped rail, with a gap between the two short arms forming the upper opening of the "T"-shaped groove. The inner ends of the two short arms extend downward to form guide plates. The upper rail consists of two spaced-apart sliding plates whose upper parts are fixedly connected, and whose lower parts extend into the gap between the two guide plates and are folded outward and then upward to form an upward-opening "U"-shaped body. The two guide plates extend into the "U"-shaped body, and sliding plate reinforcement members are provided at the lower ends of the two sliding plates.
[0008] As a further optimization of the above technical solution, the specific structure of the skateboard reinforcement is as follows: a protrusion is formed by protruding upward in the middle of the plate, and the two side walls of the protrusion are respectively welded to the inner side walls of the two skateboards facing each other. The two sides of the plate are first folded outward and then folded upward to wrap around the outer surface of the "U" shape.
[0009] As a further optimization of the above technical solution, the upper part of the protrusion expands outward to form a strip-shaped gap in the middle. The outer surfaces of the two side walls of the strip-shaped gap are respectively welded to the opposite side walls of the two slide plates, and the lower inner surface of the protrusion is pressed together and welded.
[0010] As a further optimization of the above technical solution, the lower inner surfaces of the two guide plates are recessed to form a recessed platform, and the outer surface of the protrusion is welded to the recessed platform.
[0011] As a further optimization of the above technical solution, the upper end of the folded edge of the plate is provided with an outward flange.
[0012] As a further optimization of the above technical solution, the corners between the two side walls of the lower rail and the short arm are chamfered to form a corner reinforcement structure.
[0013] As a further optimization of the above technical solution, the bottom wall of the lower rail is recessed downward to form a bottom wall reinforcement structure.
[0014] As a further optimization of the above technical solution, rollers or bearings are provided axially spaced on the two slide plates between the two slide plate reinforcement members.
[0015] As a further optimization of the above technical solution, the roller or bearing supports the weight of the upper rail and can slide on the bottom wall of the "T" groove in the lower rail.
[0016] The outstanding advantages of this utility model compared to the prior art are:
[0017] 1. The upper rail, lower rail, and slide plate reinforcement of this utility model adopt an integrated stamping structure. The slide plate reinforcement only needs to be welded to the upper rail body, without riveting process, which simplifies the production process and reduces production cost.
[0018] 2. The stamped parts of this utility model can reduce costs and weight, require less power, and save energy.
[0019] 3. The integrated structure of this utility model, through the welding of the reinforcing member to the upper rail body, and the reinforcement structure with chamfering, concave and other concave bending designs on the plate, can improve the rigidity of the upper and lower rails on the one hand; on the other hand, when the slide rail is subjected to peel strength, the reinforcement structure can effectively prevent the upper rail from deforming, and greatly improve the peel strength of the slide rail.
[0020] 4. This utility model has a simple structure, can effectively suppress the separation of the upper rail end from the lower rail, has little sliding noise, and has low production cost, making it suitable for improving the slide rail structure of seats. Attached Figure Description
