Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to an anti-noise structure for automotive seat drawers. Background Technology

[0002] In automotive interior design, seat drawers are widely used in various models as a convenient storage space. However, as cars age, seat drawers often develop rattling noises, which not only affects passenger comfort but also reduces the overall perceived quality of the car.

[0003] Traditional car seat drawer structures typically consist of a drawer body and slide rails. The drawer body slides back and forth via the slide rails and is locked in place by a locking mechanism. However, this structure often has some design flaws. Due to factors such as manufacturing precision, material deformation, and assembly errors, a certain gap inevitably exists between the drawer body and the slide rails. When the drawer is closed, these gaps can cause collisions and friction between components during vehicle operation, resulting in abnormal noises. To eliminate these noises, the industry has made various attempts. A common method is to reduce the gaps by adding extra fasteners or adjusting the assembly process, but this method often has limited effectiveness and increases manufacturing costs and assembly difficulty. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention aims to provide a noise-proof structure for car seat drawers to solve the gap problem between the drawer body and the slide rail, thereby eliminating noise.

[0005] To achieve the above objectives, this utility model proposes an anti-noise structure for a car seat drawer, including a drawer body and slide rails arranged opposite each other on both sides of the drawer body. The drawer body has a sliding groove extending forward and backward at the position corresponding to the slide rail. The slide rail is fixed to the seat frame and extends into the sliding groove, slidingly connected to it. A locking mechanism is provided between the drawer body and the slide rail. When the locking mechanism is unlocked, the drawer body can slide forward. The system also includes a Z-axis anti-noise mechanism, which includes elastic protrusions arranged on the upper and lower sides of the front end of the slide rail and elastic protrusions arranged on the upper and lower sides of the rear end of the slide rail. The two upper elastic protrusions elastically abut upward against the upper side wall of the slide groove, and the two lower elastic protrusions elastically abut downward against the lower side wall of the slide groove, thereby eliminating the Z-axis gap between the drawer body and the slide rail. The width of the slide groove at the positions corresponding to the two front or rear elastic protrusions gradually increases from front to back. When the drawer body slides forward, the elastic protrusions automatically release their elastic contact with the slide groove.

[0006] The above solution also includes a Y-axis anti-noise mechanism. This mechanism comprises a Y-axis protrusion located at the rear end of the top of the slide rail. An opening spring is positioned on the side wall of the drawer body corresponding to the Y-axis protrusion. The opening spring extends outward, and the Y-axis protrusion elastically abuts against the opening spring inward, thereby eliminating the Y-axis gap between the drawer body and the slide rail. When the drawer body slides forward, the opening spring separates from the Y-axis protrusion, releasing the elastic abutment. This structure effectively eliminates the Y-axis gap in the drawer body, ensuring a tight fit between the drawer body and the slide rail, and reducing noise generation.

[0007] The above solution also includes an X-axis anti-noise mechanism. This mechanism comprises a flexible elbow positioned at the top front end of the slide rail. A front stop is located on the drawer body at a position corresponding to the flexible elbow. The front stop elastically abuts against the flexible elbow, thereby eliminating the X-axis gap between the drawer body and the slide rail. When the drawer body slides forward, the front stop separates from the flexible elbow, releasing the elastic abutment. This structure effectively eliminates the X-axis gap in the drawer body, ensuring a tight fit between the drawer body and the slide rail, and reducing noise generation.

[0008] As can be seen, this car seat drawer anti-noise structure eliminates the gaps in the drawer body in the Z, Y and X directions, achieving all-round noise reduction and ensuring a tight fit between the drawer body and the slide rail in all directions, effectively reducing the generation of noise.

[0009] In the above solution: the elastic elbow and the opening spring are located on the same horizontal vertical line. When the drawer body slides forward until the opening spring abuts against the elastic elbow, the drawer body is at its front limit position. This structure effectively limits the sliding stroke of the drawer body and prevents the drawer body from coming off forward.

[0010] In the above solution, both the front and rear surfaces of the flexible elbow are covered with soft foam, which significantly reduces the collision noise that may occur when the drawer body slides into place, creating a quieter and higher-quality riding environment for users.

[0011] The beneficial effects of this utility model are:

[0012] 1. The elastic protrusions and the side wall of the slide rails make elastic contact, eliminating the gap in the drawer body in the Z direction. This ensures a tight fit between the drawer body and the slide rails, avoiding collision and friction noise caused by gaps when the drawer body is locked during vehicle operation. This significantly improves the quietness of the vehicle interior and provides passengers with a more comfortable riding environment.

[0013] 2. The width of the slide rail gradually increases from front to back at the position corresponding to the elastic protrusion. This allows the elastic protrusion to automatically release its elastic contact with the slide rail when the drawer body slides forward, without obstructing the normal sliding of the drawer. This design ensures both noise reduction and smooth drawer operation. 3. No additional parts are required; the structure is simple and easy to install. Attached Figure Description

[0024] like Figure 1 As shown in Figure 9, a car seat drawer structure mainly consists of a drawer body 1, slide rails 2 arranged on both sides of the drawer body 1, a Z-direction anti-noise mechanism, a Y-direction anti-noise mechanism, and an X-direction anti-noise mechanism.

[0025] The drawer body 1 has a sliding groove 3 extending forward and backward at the position corresponding to the slide rail 2. The slide rail 2 is fixed to the seat frame and extends into the sliding groove 3 for slidable connection. A locking mechanism is provided between the drawer body 1 and the slide rail 2. When the locking mechanism is unlocked, the drawer body 1 can slide forward.

[0026] The Z-direction anti-noise mechanism includes elastic protrusions 4 arranged on the upper and lower sides of the front end of the slide rail 2 and elastic protrusions 4 arranged on the upper and lower sides of the rear end of the slide rail 2. The two upper elastic protrusions 4 elastically abut against the upper side wall of the slide groove 3, and the two lower elastic protrusions 4 elastically abut against the lower side wall of the slide groove 3, thereby eliminating the Z-direction gap between the drawer body 1 and the slide rail 2.

[0027] The width of the slide groove 3 at the positions of the two elastic protrusions 4 at the front end or the two elastic protrusions 4 at the rear end gradually increases from front to back. When the drawer body 1 slides forward, the elastic protrusions 4 can automatically release their elastic contact with the slide groove 3.

[0028] The Y-direction noise reduction mechanism includes a Y-direction protrusion 5 located at the top rear end of the slide rail 2. An opening spring 6 is provided on the side wall of the drawer body 1 at the position corresponding to the Y-direction protrusion 5. The opening spring 6 extends outward, and the Y-direction protrusion 5 elastically abuts against the opening spring 6 inward, thereby eliminating the Y-direction gap between the drawer body 1 and the slide rail 2.

[0029] When the drawer body 1 slides forward, the opening spring 6 can separate from the Y-direction protrusion 5, thereby releasing the elastic contact with the Y-direction protrusion 5. This structure effectively eliminates the gap in the Y-direction of the drawer body 1, ensuring a tight fit between the drawer body 1 and the slide rail 2, and reducing the generation of abnormal noise.

[0030] The X-direction noise reduction mechanism includes an elastic elbow 7 located at the top front end of the slide rail 2. A front stop 8 is provided on the drawer body 1 at the position corresponding to the elastic elbow 7. The front stop 8 elastically abuts against the elastic elbow 7 to eliminate the X-direction gap between the drawer body 1 and the slide rail 2.

[0031] When the drawer body 1 slides forward, the front stop 8 can separate from the flexible elbow 7, thereby releasing the elastic contact with the flexible elbow 7. This structure effectively eliminates the gap of the drawer body 1 in the X direction, ensuring a tight fit between the drawer body 1 and the slide rail 2, and reducing the generation of abnormal noise.

[0032] It can be seen that the anti-noise structure of the car seat drawer eliminates the gaps in the drawer body 1 in the Z direction (vertical direction), Y direction (horizontal direction), and X direction (horizontal direction, i.e., the direction of drawer sliding), realizing all-round noise elimination and ensuring a tight fit between the drawer body 1 and the slide rail 2 in all directions, effectively reducing the generation of noise.

[0033] Ideally, the flexible elbow 7 and the opening spring 6 are located on the same horizontal vertical line. When the drawer body 1 slides forward until the opening spring 6 abuts against the flexible elbow 7, the drawer body 1 is in the front limit position. This structure effectively limits the sliding stroke of the drawer body 1 and prevents the drawer body 1 from coming off forward.

[0034] Ideally, both the front and rear surfaces of the flexible elbow 7 are covered with soft foam, which significantly reduces the collision noise that may occur when the drawer body 1 slides into place, creating a quieter and higher-quality riding environment for users.
