AI Technical Summary
The existing automobile trunk curtain lap parts are prone to abnormal noise during the vehicle's driving, mainly because the contact surface between the lap parts and the inner side wall of the clamp slot is directly faced and there is a gap.
A kind of anti-lap-proof shield curtain is designed. The head of the lap-piece is provided with a groove and a tapered slope is provided with a tapered slope to reduce the direct contact between the lap-piece and the inner wall of the lock groove, and the tapered slope is closely fitted with the peripheral wall of the lock groove to reduce vehicle sway.
By changing the end structure of the lap member and increasing the taper slope, the contact noise between the lap member and the slot is effectively reduced, and abnormal noise during the vehicle is reduced.

Abstract
Description
Technical Field
[0001] The present application relates to the field of automobile component technology, and in particular to a covering curtain that prevents abnormal noise from overlapping parts. Background Art
[0002] The shade curtain used on the trunk of a car is commonly known as the trunk shade curtain, which is mainly used to cover the trunk loaded with items to make it beautiful and tidy. At present, the more common shade curtain generally includes a longitudinal cylindrical outer tube, an outer wall of which is axially provided with a long strip opening, and the inner cavity of the outer tube accommodates a retractable cloth curtain.
[0003] When installing the blind, the ends of the outer tube are covered with lap joints, and then the lap joints are clamped in the slot inside the trunk of the car. The contact surface between the existing lap joints and the inner side wall of the slot is a straight surface with a large contact surface; and there is a gap between the side wall around the lap joint and the inner peripheral wall of the slot, which causes the vehicle to shake and make abnormal noises during driving. Utility Model Content
[0004] In order to improve the problem of abnormal noise caused by the overlapping parts of the curtain during the driving of the vehicle, the present application provides a curtain with anti-abnormal noise caused by the overlapping parts.
[0005] The present application provides an anti-overlapping piece abnormal noise shielding curtain adopts the following technical solution:
[0006] A covering curtain with an anti-sounding overlapped piece comprises a covering curtain body and overlapped pieces, wherein the overlapped pieces are arranged at two ends of the covering curtain body, a groove is arranged at the head of the overlapped piece, and a tapered inclined surface is arranged on the peripheral wall of the overlapped piece.
[0007] The embodiment of the present disclosure provides an anti-overlapping piece abnormal noise shielding curtain, which can achieve the following technical effects:
[0008] Changing the end from a straight surface to a groove helps avoid direct contact between the side wall of the lap joint head and the inner wall of the slot, reducing abnormal noise. The tapered slope around the lap joint fits tightly with the peripheral wall of the slot, helping to avoid shaking during vehicle driving, thereby reducing abnormal noise.
[0009] The above general description and the following description are exemplary and explanatory only and are not intended to limit the present application. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a schematic diagram of the structure of an anti-overlapping noise curtain provided in an embodiment of the present application.
[0011] Figure 2 It is a schematic diagram of the structure of the lap joint provided in an embodiment of the present application.
[0012] Explanation of the reference numerals: 1. curtain body; 2. lap joint; 3. groove; 4. tapered inclined surface. DETAILED DESCRIPTION
[0013] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0014] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.
[0015] The following is combined with Figure 1-2 This application is described in further detail.
[0016] A covering curtain with an anti-sounding overlapped piece includes a covering curtain body 1 and overlapped pieces 2. The overlapped pieces 2 are arranged at both ends of the covering curtain body 1. A groove 3 is arranged at the head of the overlapped piece 2, and a tapered inclined surface 4 is arranged on the peripheral wall of the overlapped piece 2.
[0017] Changing the end from a straight surface to a groove 3 helps avoid direct contact between the side wall of the head of the lap joint 2 and the inner wall of the slot, thereby reducing abnormal noise. When the lap joint 2 is matched with the slot, the cross-sectional size of the front end of the lap joint 2 is smaller than the cross-sectional size of the slot, thereby avoiding contact between the front end of the lap joint 2 and the peripheral wall of the slot. When the lap joint 2 moves to the middle of the slot, the tapered inclined surfaces 4 around the lap joint 2 fit tightly with the peripheral wall of the slot, thereby helping to avoid shaking during vehicle driving, thereby reducing abnormal noise.
[0018] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
