Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a snap-on automotive door sill protection strip. Background Technology

[0002] With the rapid development of the automotive industry, consumers have increasingly higher demands for vehicles. The door sill area, as a crucial passageway for passengers getting in and out of the car, not only withstands foot traffic and friction but also forms an important part of the vehicle's exterior. Therefore, this area typically requires protective strips or trim panels to provide scratch and wear resistance, protect body components, and enhance the visual appeal.

[0003] Existing technologies typically use silicone or rubber protective strips to connect and fix the door sill to the car door. These products usually rely on their own elasticity or adhesive to adhere to the sill, and with long-term use, the materials are prone to aging or loss of elasticity, leading to a weak connection. Some car exterior door sills use fixing bolts to connect the door sill trim panels, and then cover the screw holes with patches. While these panels are durable, the installation and removal process is complicated, and they leave permanent mounting holes on the car body or trim panel, compromising the vehicle's integrity. Some trim panels or protective strips that use clip-on connections rely on sealing rings for sealing and shock absorption. Their sealing effect is not tolerant of errors and is prone to failure due to assembly errors or long-term vehicle vibration. Utility Model Content

[0004] To address the shortcomings of the existing technology described above, this utility model provides a snap-on car door sill protection strip.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a snap-on car door sill protection strip, including a protection strip body, the shape of the protection strip body is long strip, and the inner side of the protection strip body is provided with a plurality of snap-on groups for fixed connection.

[0006] Preferably, the shape of the protective strip body matches the contour of the front or rear door sill of the car. For the different sheet metal shapes and curvatures of the front and rear doors, the present invention provides two shapes of protective strip bodies to ensure a tight fit with the car body.

[0007] Preferably, the lower front surface of the protective strip body is provided with a raised structure for anti-slip and tactile warning.

[0008] Preferably, the front of the protective strip body is provided with a raised auxiliary installation arrow. When installing the protective strip, the auxiliary installation arrow is aligned with the splicing gap of the original vehicle door sill rubber strip, which can achieve quick positioning without the need for tool measurement, significantly reducing the installation time of the door sill.

[0009] Preferably, the buckle assembly is directly connected to the protective strip body to form an integral component, avoiding the disadvantages of separate buckles such as easy loss and cumbersome installation.

[0010] Preferably, the buckle assembly includes a front fixing buckle disposed on the outer side and a rear fixing buckle disposed on the inner side, wherein the front fixing buckle and the rear fixing buckle are located on the reverse side of the protective strip body to enhance the firmness.

[0011] Preferably, the front fixing clips are arranged at intervals along the outer edge of the body for connecting to the outer structure of the door sill; the rear fixing clips are arranged at intervals along the inner edge of the body for connecting to the inner structure of the door sill. The front and rear fixing clips are asymmetrically staggered to ensure installation stability.

[0012] Preferably, the front fixing buckle and the rear fixing buckle have opposite fastening directions: the hook opening of the front fixing buckle faces the front of the protective strip body and is used to fasten the outer structure of the sill; the hook opening of the rear fixing buckle faces the rear of the protective strip body and is used to fasten the inner structure of the sill.

[0013] Preferably, the number and spacing of the front fixing buckle and the rear fixing buckle are set according to the length of the protective strip body. Preferably, the number of front fixing buckles of the front door sill protective strip is 2-3 and the number of rear fixing buckles is 2-4.

[0014] Preferably, the outer structure of the sill connected to the front fixing buckle is the gap of the vehicle's rubber plastic pad, and the front fixing buckle is snapped into the gap during installation.

[0015] Preferably, the inner structure of the sill connected to the rear fixing buckle is the rubber edge of the vehicle's plastic parts, and the rear fixing buckle is fixed to the rubber edge during installation.

[0016] The installation steps for the snap-on car door sill protector are as follows: Clean the front / rear door sills of the car, tilt the sill protector strip to embed it into the vehicle sill rubber strip, and compare the installation position; Align the positions of both ends, align the arrow on the protective strip with the seam of the original door sill rubber strip, and insert the front fixing buckle into the seam to tighten it; After securing the front retaining clips, install the rear retaining clips. Snap the rear retaining clips into the inner gap of the original car door sill plastic part. Once all retaining clips are secured, press them down.

[0017] Compared with the prior art, the beneficial effects of this utility model are: by matching the appearance shape of the car door sill and cooperating with the front and rear fixing buckles, the door sill protection strip is firmly connected, easy to install and disassemble, will not damage the car body, and has a high overall aesthetic appearance after installation; the front and rear fixing buckles are directly connected to the door sill protection strip body, avoiding the loss of parts and making the installation and disassembly process simpler.
