Description

A high-strength fully enclosed dustproof structure for automobile seat slides Technical Field

[0001] The invention relates to the field of automobile seat slide rails, in particular to a high-strength fully enclosed dustproof structure for automobile seat slide rails. Background Art

[0002] In existing commercial vehicles, seats are typically adjustable from within the vehicle. However, because the upper surface of the seat rails must be flush with the interior floor during installation, dust from the vehicle easily enters the rail cavity, affecting the operation of the lead screw.

[0003] Therefore, the seat rails of commercial vehicles usually adopt dustproof rails. At present, dustproof rails usually adopt the method of locking and dustproofing by using rubber strips to buckle each other at the track opening.

[0004] While the aforementioned dust-proofing method for the rails achieves a certain degree of dust-proofing in actual use, heavy debris can fall onto the rubber strips of the rails, creating gaps between the interlocking rubber strips. This can then allow other debris to fall into the rails, affecting their operation. Furthermore, some female passengers wearing high heels can easily slip and get stuck in the rails due to the lack of strength in the rubber strips, leading to sprains. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-strength fully enclosed dustproof structure for automobile seat slide rails to solve the problems existing in the above-mentioned prior art, effectively improve the strength of the slide rail dustproof structure, and ensure the dustproof performance of the slide rail.

[0006] To achieve the above object, the present invention provides the following solutions:

[0012] As one embodiment, the rebound structure 9 includes a torsion spring 91 arranged between each dust guard in the dust guard group 6 and the rotating shaft 5, the torsion spring 91 is arranged on the rotating shaft 5, and one end of the torsion spring 91 is connected to the corresponding dust guard; the torsion spring 91 is used to rebound and reset the dust guard in the dust guard group 6 to a state of abutting against the support seat 8.

[0013] As an embodiment, both ends of the shift plate 7 are provided with a guide structure 11 , and the guide structure 11 is used to guide the dust shields in the dust shield group 6 to unfold and reset.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] The purpose of the present invention is to provide a high-strength fully enclosed dustproof structure for automobile seat slide rails to solve the problems existing in the prior art, effectively improve the strength of the slide rail dustproof structure, and ensure the dustproof performance of the slide rail.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] As shown in Figures 1 to 7, a high-strength, fully enclosed dustproof structure for automotive seat rails in this embodiment includes two opposing seat rails 1. Each seat rail 1 defines a slide groove 3 and a seat slider connector 2 that slides along the slide groove 3. A mounting groove 4 is defined on one sidewall of the slide groove 3. A pivot axis 5 is fixedly mounted within the mounting groove 4 along the extension direction of the seat rail 1. A dust shield assembly 6 is pivotally mounted on the pivot axis 5 along the extension direction of the seat rail 1. A support base 8 is provided on the side of the slide groove 3 away from the mounting groove 4. The support base 8 is used to support the dust shield assembly 6 in a horizontal position. A shift plate 7 is provided on the side of the seat slider connector 2 near the pivot axis 5. The seat slider connector 2 is used to drive the shift plate 7 to flip and unfold the adjacent dust shield. A rebound structure 9 is provided between the dust shield assembly 6 and the pivot axis 5. The rebound structure 9 is used to cause the corresponding dust shield to rebound and return to its original position after the shift plate 7 is swiped away, and is supported by the support base 8.

[0035] 2 and 4 , a buffer structure 10 is provided on the support base 8. The buffer structure 10 is used to cushion the dust shield assembly 6 during its rebound. The buffer structure 10 can provide a certain amount of cushioning to the dust shield during its rebound, thereby reducing the noise generated by the dust shield during rebound and effectively preventing damage to the dust shield during rebound.

[0036] Specifically, the buffer structure 10 includes a buffer groove 101 provided on the support base 8, and a buffer pad 102 is fixedly provided 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 shield rebounds.

[0037] Referring to Figures 3 and 5 , guide structures 11 are provided at both ends of the shift plate 7. These guide structures 11 guide the deployment and repositioning of the dust shields within the dust shield assembly 6. The guide structure 11 at the front end of the seat slider connector 2 deploys the dust shields during movement, while the guide structure 11 at the rear end prevents the dust shields from rapidly repositioning and generating excessive noise due to the rebound structure 9. Both the front and rear ends are aligned with the direction of movement of the seat slider connector 2.

[0038] Specifically, each guide structure 11 includes a guide plate 111 disposed at one end of the shift plate 7 and a guide surface 112 disposed on the guide plate 111. The guide surface 112 is disposed at the top of the guide plate 111 and is inclined from top to bottom. The guide surface 112 abuts against the inner surface of the dust shield within the dust shield assembly 6. In this embodiment, the bends on the guide surface 112 are all connected by a curved surface transition. The curved surface connection makes the relative displacement between the dust shield and the guide plate 111 more gradual, effectively increasing the life of the entire device.

[0039] On the one hand, the guide surface 112 can slow down the rebound speed of the dust guard, thereby reducing the noise when the dust guard rebounds. On the other hand, it can facilitate the deployment of the dust guard along the guide surface 112, thereby facilitating the movement of the seat slider connector 2.

[0040] 6 and 7 , the rebound structure 9 includes a torsion spring 91 disposed between each dust shield in the dust shield assembly 6 and the rotating shaft 5. The torsion spring 91 is disposed on the rotating shaft 5, and one end of the torsion spring 91 is connected to the corresponding dust shield. The torsion spring 91 is used to rebound and reset the dust shields in the dust shield assembly 6 to a horizontal position slightly tilted downward. By rotating the torsion spring 91, the force acting on the dust shield is small, making the rotation easier, and providing rebound and reset performance.

[0041] 7 , the dust shield assembly 6 includes a plurality of first dust shields 61 and second dust shields 62 that interlock with each other. The first dust shield 61 is an N-shaped plate. The first dust shield 61 includes a plate body. Both ends of the plate body have extensions perpendicular to the plate body and extending toward the second dust shield 62. U-shaped grooves are provided on both sides of the second dust shield 62. Two first dust shields 61 adjacent to the second dust shield 62 are respectively interlocked with the U-shaped grooves on both sides of the second dust shield 62. A guide cavity 63 is formed between the first dust shield 61 and the second dust shield 62. By interlocking adjacent first dust shields 61 and second dust shields 62, during the movement of the seat slider connector 2, the second dust shield 62 in the dust shield assembly 6 can drive the adjacent first dust shield 61 to move synchronously, effectively increasing the overall stability of the dust shield assembly 6. At the same time, the adjacent first dust shield 61 and the second dust shield 62 are interlocked to effectively prevent dust and debris from entering through the gap between the two. Even if dust, liquid, etc. enter from the gap, they will be retained in the guide cavity 63, thereby preventing debris from entering the seat slide rail 1, effectively improving the overall service life of the device.

[0042] It should also be noted that a confluence groove 103 may be provided on the side of the buffer pad 102 away from the mounting groove 4, and the confluence groove 103 is provided in conjunction with the guide cavity 63. The confluence groove 103 facilitates the collection of debris in the guide cavity 63 into the confluence groove 103 for subsequent cleaning.

[0043] It should also be noted that the dust shield 6 can be positioned horizontally. However, to accommodate the confluence trough 103 and the diversion cavity 63, the support surface of the support base 8 supporting the dust shield assembly 6 is slightly lower than the lower surface of the dust shield assembly 6 near the rotating shaft 5. This allows the dust shields within the dust shield assembly 6 to tilt slightly downward when they return to their original position and abut against the cushion 102, allowing debris within the diversion cavity 63 to slide into the confluence trough 103 under the action of gravity. Furthermore, the support base 8 is positioned above the dust shield and bends toward the dust shield, effectively preventing any gaps from forming between the support base 8 and the dust shield assembly 6.

[0044] The implementation principle of a high-strength, fully enclosed dust-proof structure for automobile seat slide rails in this embodiment is as follows: when the seat needs to be adjusted, the seat slider connector 2 is driven to move along the slide groove 3, and the seat slider connector 2 drives the dial plate 7 to move. The guide plate 111 located in front of the moving direction on the dial plate 7 interferes with the dust shield in front of the movement, so that the dust shield is lifted along the guide surface 112 to be unfolded, ensuring the normal movement of the seat slider connector 2; the dust shield has a closing tendency under the rebound action of the torsion spring 91. After the seat slider connector 2 passes through the unfolded dust shield, the guide surface 112 on the guide plate 111 behind the dust shield in the moving direction gradually closes, so that the guide plate 111 located behind the movement of the dial plate 7 can effectively slow down the rebound rate of the dust shield caused by the torsion spring 91, so that it can slowly abut against the buffer pad 102, effectively reducing noise; at the same time, the guide cavity 63 and the confluence groove 103 cooperate to effectively prevent dust or debris from directly entering the interior of the seat slide rail 1.

[0045] Adaptive changes based on actual needs are all within the scope of protection of the present invention.

[0046] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
