Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an electric seat rail that prevents a lighter from falling in and getting stuck. Background Technology

[0002] As cars become increasingly popular, consumers are demanding higher levels of comfort while driving and riding. Scenarios where seats are adjusted to their extreme positions are becoming more common. In these situations, the guide rail and its lead screw assembly are directly exposed, making it easy for various foreign objects to fall into the rail. While tiny objects may be negligible, small objects can cause the rail to malfunction, and lighter-shaped objects can easily start a vehicle fire.

[0003] Existing technical solutions aim to prevent foreign objects from falling in and improve the appearance by adding shielding mechanisms. For example, CN113147526A extends the fixed rail and adds a rotating shielding strip; CN219749574U adds a mechanism to the vehicle body to shield the sliding rail; and CN216993990U extends the moving rail or adds a shield above the moving rail. All three of these patents are relatively expensive and occupy a significant amount of vehicle body space or add substantial weight to the seats.

[0004] This utility model proposes an electric seat slide rail to prevent lighters from falling in and getting stuck, thus solving the problem that the cost of manufacturing existing slide rails is relatively high, and they occupy a lot of vehicle space or increase the weight of the seat itself. Summary of the Invention

[0005] In order to overcome the problems of the high cost of manufacturing sliding rails in the above-mentioned background technologies, as well as the large amount of space occupied by the rails or the significant increase in the weight of the seats themselves.

[0006] Based on the above technical concept, the technical solution adopted by this utility model is as follows:

[0007] An electric seat slide rail for preventing lighters from falling in and getting stuck includes a fixed rail and a plastic baffle. A screw assembly is installed on the inner bottom wall of the fixed rail. The plastic baffle is installed and fixed from bottom to top on the outside of the screw assembly and then fixed to the inner bottom wall of the fixed rail. The screw assembly is connected to the fixed rail by rivets one and two at both ends. A moving rail is connected to the bracket in the gearbox of the screw assembly. The moving rail is connected to the screw assembly by a locking bolt at the top.

[0008] The lead screw assembly is used to drive the sliding of the moving rail.

[0009] Further defining the above technical solution, the lead screw assembly includes a lead screw body, a gearbox sleeved on the outer side of the lead screw body, second connection holes on both sides of the gearbox, a first connection hole on the top of the moving rail for engaging with a locking bolt, a first mounting plate connected to one end of the lead screw body, and a second mounting plate connected to the other end of the lead screw body.

[0010] Further defining the above technical solution, the height of the plastic baffle is flush with the height of the lead screw body, and there are two ribs on the outer side of the plastic baffle to reduce friction with the moving rail.

[0011] To further refine the above technical solution, a plastic baffle was added between the lead screw body and the fixed rail, reducing the gap from 8mm to less than 4mm for a single gap.

[0012] Further defining the above technical solution, the plastic baffle has U-shaped holes at both ends of its top for fixing it to the bottom of the lead screw body.

[0013] Further defining the above technical solution, the moving rail has a retainer one and a retainer two installed on both sides of its bottom.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Low investment cost: The lead screw assembly and baffle are installed inside the fixed rail by rivets one and two. By adding the baffle, the gap between the lead screw assembly and the fixed rail is reduced. The height of the plastic baffle is flush with the height of the lead screw body, so that if the lighter falls in, it will lie flat on the lead screw assembly. When the moving rail moves backward, it will push the lighter out of the moving rail, thus preventing the lighter from getting stuck in the gap between the lead screw assembly and the fixed rail at a low cost.

[0016] Small space occupation: Existing technical solutions require additional components that either occupy the vehicle body space or the frame space. The new components of this technical solution are located inside the slide rail and will not occupy additional seat space or vehicle body space.

[0017] High replaceability: Since the new components of this solution are inside the slide rail, existing mass-produced projects can be directly replaced without design changes to the seat or body when upgrading to this solution. Attached Figure Description

[0025] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail below.

[0026] Example 1: This example provides an electric seat slide rail to prevent lighters from falling into and getting stuck, such as... Figure 1 and Figure 4 As shown, this design solves the problems of high manufacturing costs for sliding rails, which occupy significant vehicle space and increase seat weight. It includes a fixed rail 4 and a plastic baffle 3. A lead screw assembly 2 is installed on the inner bottom wall of the fixed rail 4. The plastic baffle 3 is installed and fixed from bottom to top on the outside of the lead screw assembly 2 and then fixed to the inner bottom wall of the fixed rail 4. The lead screw assembly 2 is connected to the fixed rail 4 by rivets 5 and 8 at both ends. A moving rail 1 is connected to the gearbox bracket of the lead screw assembly 2. The moving rail 1 is connected to the lead screw assembly 2 by a locking bolt 9 at the top. The lead screw assembly 2 drives the moving rail 1 to slide.

[0027] During assembly, first assemble the moving rail 1 and the fixed rail 4, then assemble the lead screw assembly 2 and the plastic baffle 3. Next, insert the lead screw assembly 2 and the plastic baffle 3 between the moving rail 1 and the fixed rail 4, and rivet the lead screw assembly 2 and the fixed rail 4 with rivet 1 5 and rivet 2 8. Finally, bolt the moving rail 1 and the lead screw assembly 2 with locking bolt 9.

[0028] Combination Figure 1 and Figure 2 In an embodiment of this utility model, the lead screw assembly 2 includes a lead screw body 21, a gearbox 22 sleeved on the outer side of the lead screw body 21, a second connecting hole 221 on both sides of the gearbox 22, a first connecting hole 11 on the top of the moving rail 1 for cooperating with the locking bolt 9, a first mounting plate 23 fixedly connected to one end of the lead screw body 21, and a second mounting plate 24 fixedly connected to the other end of the lead screw body 21.

[0029] Locking bolts 9 are respectively inserted into the first connecting hole 11 and the second connecting hole 221, so that the moving rail 1 and the gearbox 22 can be fixedly connected. The gearbox 22 slides along the outside of the lead screw body 21, so that the moving rail 1 slides along the fixed rail 4.

[0030] Combination Figure 1 In this embodiment of the utility model, the height of the plastic baffle 3 is flush with the height of the lead screw body 21, and there are two ribs on the outer side of the plastic baffle 3 to reduce friction with the moving rail 1.

[0031] Combination Figure 1 In this embodiment of the utility model, the plastic baffle 3 has U-shaped holes at both ends of its top for fixing it to the bottom of the lead screw body 21.

[0032] The two ends of the lead screw body 21 are inserted into the U-shaped holes at both ends of the plastic baffle 3, so that the lead screw assembly 2 can be installed on the top of the plastic baffle 3. At the same time, the plastic baffle 3 is made of polyoxymethylene material, which gives the plastic baffle 3 high strength and rigidity, and can withstand large external forces without easily deforming, effectively extending the service life of the plastic baffle 3.

[0033] Example 2: Reference Figure 1 and Figure 3 To improve the stability of the moving rail 1 during sliding, the bottom of the moving rail 1 is equipped with a retainer 6 and a retainer 7 on both sides respectively.

[0034] By placing cage 6 and cage 7 between the outer side of moving rail 1 and the inner side of fixed rail 4, direct contact between moving rail 1 and fixed rail 4 can be prevented when moving rail 1 slides along fixed rail 4, thus avoiding excessive wear caused by sliding friction, ensuring stable movement of moving rail 1 along the inside of fixed rail 4, and maintaining smooth operation.

[0035] Example 3: Reference Figure 5To address the issue of lighters easily getting stuck when falling into the gap between the lead screw body 21 and the fixed rail 4, a plastic baffle 3 was added between the lead screw body 21 and the fixed rail 4, reducing the gap from 8mm to less than 4mm for each individual gap. Since lighters are generally 8-10mm thick, and the gap between the lead screw body 21 and the fixed rail 4 is less than 4mm, this ensures that the lighter will lie flat on the lead screw body 21 after falling in.

[0036] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
