Abstract
Description
Technical Field
[0001] This application relates to the field of automotive seat slide rails, and more particularly to a high-strength, fully enclosed dustproof structure for automotive seat slide rails. Background Technology
[0002] In existing commercial vehicles, seats are typically adjustable within the passenger compartment. However, the upper surface of the seat rails must be flush with the interior floor of the passenger compartment during installation; the rails cannot protrude. This allows dust from inside the passenger compartment to easily enter the inner cavity of the rails, thus affecting the operation of the lead screw.
[0003] Therefore, the seat rails of commercial vehicles are usually dustproof rails. Currently, dustproof rails are usually sealed by interlocking rubber strips at the opening of the rail.
[0004] While the aforementioned dustproof method for the sliding rails achieves a certain degree of dust prevention in actual use, when heavy debris falls onto the rubber strips of the rails, gaps can appear between the interlocking strips. This allows other debris to fall into the rails through these gaps, affecting their operation. Furthermore, if female passengers wear high heels, the rubber strips may not be strong enough, making them prone to slipping and falling into the rail's cavity, potentially leading to ankle sprains. Summary of the Invention
[0005] In order to effectively improve the strength of the dustproof structure of the slide rail and ensure the dustproof performance of the slide rail, this application provides a high-strength fully enclosed dustproof structure for automotive seat slide rails.
[0006] This application provides a high-strength, fully enclosed dustproof structure for automotive seat slide rails, employing the following technical solution: A high-strength, fully enclosed dustproof structure for automotive seat slide rails includes a seat slide rail and a seat slider connector that slides along the seat slide rail. The seat slide rail has a groove for the seat slider connector to slide in. A mounting groove is formed on one side wall of the groove. A rotating shaft is fixedly installed in the mounting groove along the extension direction of the seat slide rail. A dust baffle assembly is rotatably installed on the rotating shaft along the extension direction of the seat slide rail. The dust baffle assembly is composed of multiple dust baffles fastened together. A lever is provided on the side of the seat slider connector near the rotating shaft. The seat slider connector is used to drive the lever to flip and unfold the adjacent dust baffle. A support base is provided on the side of the slide away from the mounting groove. A spring-loaded structure is provided between the dust baffle assembly and the rotating shaft. The spring-loaded structure is used to drive the corresponding dust baffle to spring back and reset after the push plate is moved away, and is supported by the support base.
[0007] By adopting the above technical solution, the dust baffles in the dust baffle assembly are horizontally positioned under normal conditions and supported by support seats. This ensures the dustproof performance of the seat slide rails while improving the strength of the dustproof structure, preventing gaps from forming between the seat slide rails. Simultaneously, a combination of a lever and a spring-loaded structure is used. When the slider moves, the lever flips and unfolds the dust baffles adjacent to the slider. When the slider moves away, the dust baffles return to their original position under the action of the spring-loaded structure and are supported by the support seats, ensuring dust prevention without affecting the normal movement of the seat.
[0008] Preferably, the dust baffle assembly includes a plurality of first dust baffles and a second dust baffle that are interlocked with each other. The first dust baffle is an N-shaped plate, and the second dust baffle has U-shaped grooves on both sides. Two adjacent first dust baffles are respectively interlocked with the U-shaped grooves on both sides of the second dust baffle. A flow guiding cavity is formed between the first dust baffle and the second dust baffle.
[0009] By adopting the above technical solution, and using the interlocking method of adjacent first and second dust baffles, the adjacent first and second dust baffles within the dust baffle assembly move synchronously during the movement of the seat slider connector, effectively increasing the overall stability of the dust baffle assembly. Simultaneously, the interlocking method of adjacent dust baffles effectively prevents dust and debris from entering through the gap between the two steel plates. Even if dust or liquids enter through the gap, they will remain in the guide cavity, thus preventing debris from entering the seat slide rail, effectively improving the overall performance and service life of the device.
[0010] Preferably, the support base is provided with a buffer structure, which is used to buffer the dust baffle assembly when it rebounds and resets.
[0011] By adopting the above technical solution, the buffer structure can provide a certain buffer to the dust baffle when it resets and rebounds, thereby reducing the noise generated when the dust baffle rebounds and effectively preventing damage to the dust baffle during rebound.
[0012] Preferably, the buffer structure includes a buffer groove formed on the support base, and a buffer pad is fixedly disposed in the buffer groove.
[0013] By adopting the above technical solution, the buffer pad can provide the rebounding dust baffle with an upward elastic force, and the noise is relatively small when it is impacted.
[0014] Preferably, a flow channel is provided on the side of the buffer pad away from the mounting groove, and the flow channel is configured to cooperate with the flow guiding cavity.
[0015] By adopting the above technical solution, it is easy to concentrate the debris located in the guide cavity into the manifold, which facilitates subsequent cleaning.
[0016] Preferably, the rebound structure includes a torsion spring disposed between each dust baffle and the rotating shaft in the dust baffle assembly, the torsion spring being disposed on the rotating shaft, and one end of the torsion spring being connected to the corresponding dust baffle. The torsion spring is used to spring back the dust baffles in the dust baffle assembly to a horizontal position.
[0017] By adopting the above technical solution, the torsion spring rotates the dust baffle with a smaller force, making it easier to rotate, and it also has the ability to rebound and reset.
[0018] Preferably, both ends of the lever are provided with guide structures, which are used to guide the dust baffles in the dust baffle assembly to unfold and reset.
[0019] By adopting the above technical solution, the guide structure is located at the moving front end of the seat slider connector to unfold the dust baffle, and at the moving rear end of the seat slider connector to prevent the dust baffle from quickly resetting and to prevent the dust baffle from generating a lot of noise under the action of the rebound structure.
[0020] Preferably, each of the guide structures includes a guide plate disposed at one end of the lever and a guide surface disposed on the guide plate; The guide surface is disposed on the top of the guide plate, the guide surface is inclined from top to bottom, and the guide surface abuts against the inner surface of the dust baffle in the dust baffle assembly.
[0021] By adopting the above technical solution, the guide surface can slow down the rebound speed of the dust baffle, thereby reducing the noise when the dust baffle rebounds. On the other hand, it can facilitate the unfolding of the dust baffle along the guide surface, thereby facilitating the movement of the seat slider connector.
[0022] Preferably, all bends on the guide surface are connected by arc surfaces.
[0023] By adopting the above technical solution, the arc-shaped connection makes the relative displacement between the dust baffle and the guide plate smoother, effectively increasing the overall lifespan of the device.
[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The dust baffles in the dust baffle assembly are horizontally positioned under normal conditions and supported by support seats. This ensures the dustproof performance of the seat slide rails while enhancing the strength of the dustproof structure and preventing gaps between the slide rails. A combination of a lever and a spring-loaded mechanism is used. When the slider moves, the lever flips and unfolds the dust baffles adjacent to the slider. When the slider moves away, the dust baffles spring back to their original position under the action of the spring-loaded mechanism and are supported by the support seats. This ensures dust protection without affecting the normal movement of the seat. 2. By utilizing the interlocking mechanism of adjacent first and second dust baffles, the adjacent first and second dust baffles within the dust baffle assembly move synchronously during the movement of the seat slider connector, effectively increasing the overall stability of the dust baffle assembly. Simultaneously, the interlocking mechanism of adjacent dust baffles effectively prevents dust and debris from entering through the gap between the two steel plates. Even if dust or liquids enter through the gap, they will remain within the guide cavity, thus preventing debris from entering the seat slide rail, effectively improving the overall performance and service life of the device. 3. The buffer structure provides a certain buffer when the dust baffle returns to its original position, thereby reducing the noise generated during the return and effectively preventing damage to the dust baffle during the return. 4. The guide surface can slow down the rebound speed of the dust baffle, thereby reducing the noise during the rebound. On the other hand, it can facilitate the unfolding of the dust baffle along the guide surface, thus facilitating the movement of the seat slider connector. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.
[0028] This application discloses a high-strength, fully enclosed dustproof structure for automotive seat slide rails.
[0029] Reference Figures 1 to 5 The high-strength, fully enclosed dustproof structure for automotive seat rails includes two opposing seat rails 1. Each seat rail 1 has a groove 3, and each seat rail 1 has a seat slider connector 2 that slides along the groove 3. A mounting groove 4 is provided on one side wall of the groove 3. A rotating shaft 5 is fixedly installed in the mounting groove 4 along the extension direction of the seat rail 1. A dust baffle assembly 6 is rotatably mounted on the rotating shaft 5 along the extension direction of the seat rail 1. A support seat 8 is provided on the side of the groove 3 away from the mounting groove 4, supporting the horizontally positioned dust baffle assembly 6. A lever 7 is provided on the side of the seat slider connector 2 near the rotating shaft 5. The seat slider connector 2 drives the lever 7 to flip and unfold the adjacent dust baffle. A spring-loaded structure 9 is provided between the dust baffle assembly 6 and the rotating shaft 5. The spring-loaded structure 9 causes the corresponding dust baffle to spring back and reset after the lever 7 is moved, and is supported by the support seat 8.
[0030] Reference Figure 2 and Figure 4 A buffer structure 10 is provided on the support base 8. The buffer structure 10 is used to buffer the dust baffle assembly 6 when it rebounds and resets. The buffer structure 10 can provide a certain buffer to the dust baffle when it resets and rebounds, thereby reducing the noise generated when the dust baffle rebounds and effectively preventing damage to the dust baffle during rebound.
[0031] Specifically, the buffer structure 10 includes a buffer groove 101 formed on the support base 8, and a buffer pad 102 is fixedly disposed in the buffer groove 101. In this embodiment, the buffer pad 102 can be a flexible rubber pad, which can effectively reduce the noise when the dust baffle rebounds.
[0032] Reference Figure 3 and Figure 5 Both ends of the lever 7 are provided with guide structures 11, which are used to guide the dust baffles in the dust baffle assembly 6 to unfold and reset. The guide structure 11 is located at the moving front end of the seat slider connector 2 to unfold the dust baffles, and located at the moving rear end of the seat slider connector 2 to prevent the dust baffles from resetting quickly and to prevent the dust baffles from generating excessive noise under the action of the rebound structure 9.
[0033] Specifically, each guide structure 11 includes a guide plate 111 disposed at one end of the lever 7 and a guide surface 112 disposed on the guide plate 111. The guide surface 112 is disposed on the top of the guide plate 111, and is inclined from top to bottom, and abuts against the inner surface of the dust baffle in the dust baffle assembly 6. In this embodiment, the bends on the guide surface 112 are all connected by arc surfaces. The arc surface connection makes the relative displacement between the dust baffle and the guide plate 111 smoother, effectively increasing the overall lifespan of the device.
[0034] The guide surface 112 can slow down the rebound speed of the dust baffle, thereby reducing the noise when the dust baffle rebounds. On the other hand, it can facilitate the unfolding of the dust baffle along the guide surface 112, thereby facilitating the movement of the seat slider connector 2.
[0035] Reference Figure 6 and Figure 7 The rebound structure 9 includes a torsion spring 91 disposed between each dust baffle in the dust baffle assembly 6 and the rotating shaft 5. The torsion spring 91 is mounted on the rotating shaft 5, and one end of the torsion spring 91 is connected to the corresponding dust baffle. The torsion spring 91 is used to spring back the dust baffle in the dust baffle assembly 6 to a horizontal position with a slight downward tilt. By using the rotation of the torsion spring 91, the force exerted by the torsion spring 91 on the dust baffle is small, making rotation easy, and it also has the performance of springback.
[0036] Reference Figure 7 The dust baffle assembly 6 includes multiple interlocking first dust baffles 61 and second dust baffles 62. The first dust baffles 61 are N-shaped plates, and each of the second dust baffles 62 has a U-shaped groove on both sides. Two adjacent first dust baffles 61 are interlocked within the U-shaped grooves on either side of the second dust baffle 62, forming a flow guide cavity 63 between them. By interlocking adjacent first dust baffles 61 and second dust baffles 62, the adjacent first dust baffles 61 and second dust baffles 62 move synchronously during the movement of the seat slider connector 2, effectively increasing the overall stability of the dust baffle assembly 6. Simultaneously, the interlocking of adjacent dust baffles effectively prevents dust and debris from entering through the gap between the two steel plates. Even if dust or liquid enters through the gap, it will remain in the flow guide cavity 63, thus preventing debris from entering the seat slide rail 1 and effectively extending the overall service life of the device.
[0037] It should also be noted that a confluence channel 103 may be provided on the side of the buffer pad 102 away from the mounting groove 4, and the confluence channel 103 is configured to cooperate with the guide cavity 63. The confluence channel 103 facilitates the collection of debris located in the guide cavity 63 into the confluence channel 103, which is convenient for subsequent cleaning.
[0038] It should also be noted that, in order to cooperate with the manifold 103 and the guide cavity 63, the support base 8 can be set slightly downward, so that when the dust baffle in the dust baffle assembly 6 returns to its original position, it is slightly tilted downward and abuts against the buffer pad 102, allowing the debris in the guide cavity 63 to move into the manifold 103 by gravity. Furthermore, the support base 8 is positioned above the dust baffle and bends towards it, effectively preventing gaps between the support base 8 and the dust baffle assembly 6.
[0039] The implementation principle of a high-strength fully enclosed dustproof structure for automotive seat slide rails in this application embodiment is as follows: when seat adjustment is required, the seat slider connector 2 is moved along the slide groove 3, and the seat slider connector 2 drives the lever 7 to unfold the dust baffle in front of the movement, ensuring the normal movement of the seat slider connector 2. Furthermore, the guide plate 111 located behind the moving plate 7 can effectively slow down the rate at which the dust baffle plate rebounds from the torsion spring 91, allowing it to gently abut against the buffer pad 102, thus effectively reducing noise. Meanwhile, the flow guide cavity 63 and the flow channel 103 work together to effectively prevent dust or debris from directly entering the interior of the seat slide rail 1.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
