Electric long sliding rail retainer mechanism

Abstract

The utility model relates to the technical field of electric long sliding rails, in particular to an electric long sliding rail elastic retainer mechanism which comprises a retainer (51), an elastic raised line (52) arranged on the retainer (51) and two limiting raised lines (53) arranged at the two ends of the elastic raised line (52). An elastic piece (54) which abuts against the elastic protruding strip (52) is arranged between the two limiting protruding strips (53) and the elastic protruding strip (52). Due to the adoption of the structural design, that is, the retainer mechanisms are arranged between the side walls of the lower slide rail and the upper slide rail, not only can the stable operation of the long slide rail be ensured, but also the noise generated in the operation process can be reduced to the greatest extent, and the quietness is good.

Description

Technical Field

[0001] This utility model relates to the field of electric long slide rail technology, and in particular to an electric long slide rail retainer mechanism. Background Technology

[0002] With the rapid development of the automotive industry, electric seats have become a mainstream feature in passenger vehicles due to their convenience and comfort. As a core functional component of electric seats, the performance of the long sliding rail assembly directly affects the smoothness, stability, and safety of seat adjustment.

[0003] Chinese utility model patent CN213920748U discloses a long slide rail for a seat, including a left slide rail and a right slide rail, each having an upper slide rail and a lower slide rail slidably connected to each other. The left and right slide rails each include a ball bearing circulation device. In the assembled state, the ball bearing circulation device is fixed to the side wall of the upper slide rail facing the lower slide rail and is housed between the side walls of the upper and lower slide rails. The balls in the ball bearing circulation device allow the upper slide rail to slide relative to the lower slide rail. The ball bearing circulation device includes an upper guard plate, a lower guard plate, and a ball bearing retainer connected to each other. Multiple balls are housed in a first raceway formed by the upper guard plate and the ball bearing retainer, and / or a second raceway formed by the lower guard plate and the ball bearing retainer. When the upper slide rail slides relative to the lower slide rail, at least one of the multiple balls contacts the lower slide rail and rolls upwards. Due to design tolerances or long-term wear, the gap between the upper and lower rails of this type of seat may exceed the allowable threshold, which will produce knocking noises when driving on bumpy roads, and the noise level is high during operation, with generally poor quietness.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an electric long slide rail with lower noise and better quietness.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An electric long slide rail retainer mechanism includes a retainer, an elastic protrusion disposed on the retainer, and two limiting protrusions disposed at both ends of the elastic protrusion. A spring sheet that abuts against the elastic protrusion is disposed between the two limiting protrusions and the elastic protrusion.

[0008] As a further embodiment of this utility model, each of the limiting protrusions has a groove on the side facing the elastic protrusion, and the two ends of the elastic piece are respectively located in the two grooves.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] Due to the above structural design, which includes a retainer mechanism between the sidewalls of the lower slide rail and the upper slide rail, not only can the long slide rail be run smoothly, but the noise generated during operation is also reduced to the greatest extent, resulting in good quietness.

[0014] 531 - Groove. Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0018] The features and performance of this utility model will be further described in detail below with reference to the embodiments. Example

[0019] like Figure 1 As shown, this application discloses an electric long slide rail retaining mechanism, including a retainer 51, an elastic protrusion 52 disposed on the retainer 51, and two limiting protrusions 53 disposed at both ends of the elastic protrusion 52. Each limiting protrusion 53 has a groove 531 on the side facing the elastic protrusion 52. A spring piece 54 is disposed between the two limiting protrusions 53 and the elastic protrusion 52 to press against the elastic protrusion 52. The two ends of the spring piece 54 are respectively located in the two grooves 531. Through the above structural design, the elastic protrusion and the limiting protrusion are integrally formed with the retainer and are made of injection molding. Under the action of the elastic protrusion and the spring piece, the elastic protrusion is always pressed against the outer wall surface of the upper slide rail, which can eliminate the gap between the upper slide rail and the lower slide rail and the gap caused by processing errors. After adding lubricating oil, there is almost no friction noise, ensuring quiet operation.

[0020] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure and good quietness.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
