Description

Technical Field

[0001] This utility model relates to the field of general vehicle technology, and in particular to a car wheel arch connection structure that is easy to assemble and disassemble. Background Technology

[0002] In the field of automobile manufacturing and maintenance, wheel covers are an indispensable component. They not only protect the vehicle body from the impact of foreign objects such as mud, sand and stones kicked up by the wheels during driving, reducing damage to the vehicle body, but also optimize the vehicle's aerodynamic performance, reduce wind resistance, and improve fuel economy. At the same time, aesthetically pleasing wheel covers also enhance the overall appearance and quality of the car to a certain extent.

[0003] Currently, most car wheel covers on the market are connected using screw fastening, which is a common and traditional connection method. In structures using screw fastening, repair personnel need to use specialized tools such as screwdrivers and wrenches to unscrew multiple screws one by one in order to remove the wheel cover. This process is not only tedious and time-consuming, but also involves a large number of screws. During disassembly and installation, screws are prone to being lost or missed. Once a screw is lost, not only is it necessary to spend extra time finding or purchasing matching screws, but the mismatch of screw specifications may also affect the stability of the wheel cover installation, thereby affecting driving safety. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a car wheel cover connection structure that is easy to disassemble and assemble. This solves the problem that maintenance personnel need to use special tools such as screwdrivers and wrenches to unscrew multiple screws one by one to remove the wheel cover. This process is not only tedious and time-consuming, but also involves a large number of screws. During disassembly and installation, screws are prone to being lost or missed. Once a screw is lost, not only is it necessary to spend extra time to find or buy matching screws, but the mismatch of screw specifications may also affect the installation stability of the wheel cover, thereby affecting driving safety.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a car wheel cover connection structure that is easy to assemble and disassemble, including a car wheel cover, wherein the car wheel cover is provided with eight elastic buckle components, and the eight elastic buckle components are arranged in pairs; A set of elastic buckle components includes two mounting bases and two positioning sliders. Four fixing bolts are threaded to one end of the outer wall of each of the two positioning sliders. Positioning slider grooves are opened on one end of the outer wall of each of the two mounting bases. Elastic card limiting grooves are opened on the left and right inner walls of the positioning slider grooves. The two positioning sliders have elastic card mounting slots on their left and right outer walls. Each of the four elastic card mounting slots has an elastic element inside. When all four elastic elements are arc-shaped elastic cards, the outer walls of the two positioning sliders are slidably connected to the inside of the corresponding positioning slider grooves. Each of the four elastic card mounting slots has four fixed rods fixedly connected inside. Each of the four elastic elements has four grooves on its outer wall. All four sets of elastic buckle assemblies are installed on the rear inner wall of the car wheel cover.

[0006] Preferably, the elastic element is installed inside the corresponding elastic card mounting slot through four sliding grooves and four fixing rods inside the elastic card mounting slot.

[0007] Preferably, the inner walls of the four elastic card limiting grooves are all arc-shaped.

[0008] Preferably, the arc-shaped outer walls of the four elastic elements are used in conjunction with the inner walls of the corresponding elastic card limiting grooves.

[0009] Preferably, one end of each of the eight mounting bases has four mounting holes on its outer wall.

[0010] Preferably, when all sixteen elastic elements are trapezoidal elastic cards, the outer wall of the trapezoidal surface of the sixteen elastic elements respectively cooperates with the trapezoidal elastic card limiting grooves opened on the left and right inner walls of the mounting base.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This easy-to-install and disassemble car wheel cover connection structure achieves "tool-free" operation through the cooperation of the arc-shaped or trapezoidal elastic card and the elastic card limiting groove in the elastic buckle assembly. During installation, simply push the car wheel cover to make the positioning slider slide along the positioning slider groove of the mounting base. The elastic element automatically deforms under compression and locks into the limiting groove to complete the fixation. During disassembly, simply pull the wheel cover in the opposite direction. The elastic element is squeezed and contracted by the edge of the limiting groove to disengage, and the positioning slider slides out of the groove to complete the separation. The whole process does not require tool assistance, which greatly improves the operational efficiency of vehicle maintenance, wheel cover replacement or cleaning, and is especially suitable for scenarios such as quick repair.

[0014] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0017] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0018] Example 1: Reference Figure 1-4 Basic implementation example for standard vehicle models (arc-shaped elastic card + ordinary positioning slider) This embodiment is applicable to conventional vehicle models such as family cars and urban SUVs. By combining an arc-shaped elastic card with a regular positioning slider, the basic installation and adaptation of the car wheel cover can be achieved, meeting daily use needs.

[0019] Structural fit and installation effect: The elastic element 8 adopts an arc-shaped elastic card (spring steel material), which is installed in the elastic card mounting groove 4 of the positioning slider 6 through the fixing rod 5 and the sliding groove 7. It fits tightly with the arc-shaped elastic card limiting groove 9 of the mounting base 2. The positioning slider 6 is made of ordinary engineering plastic material and is slidably connected with the positioning slider groove 3. Four fixing bolts 11 ensure that the positioning slider is stably installed.

[0020] During installation, the arc-shaped elastic card is deformed by pressure during insertion, and automatically pops open after being inserted into the limiting groove, forming a reliable lock. It is suitable for regular car models with relatively standard tire sizes, and is easy to install and remove. It is low in cost and suitable for mass assembly in car manufacturing plants or ordinary replacement in the aftermarket.

[0021] Application effects: The structure is simple and versatile, which can meet the wheel cover installation requirements of conventional vehicle models, is easy to maintain, and is compatible with most common tire specifications.

[0022] Example 2: Reference Figure 5 Implementation example of robust adaptation for off-road vehicles (trapezoidal elastic card + reinforced positioning slider) This embodiment is designed for off-road vehicles, pickup trucks, and other vehicles that need to cope with complex road conditions. It enhances the stability and impact resistance of the wheel arches by using trapezoidal elastic cards and reinforced positioning sliders.

[0023] The robust adaptation structure is as follows: the elastic element 8 is replaced with a trapezoidal elastic card 10, which provides a stronger clamping force by using the wedge-shaped engagement between the trapezoidal surface and the limiting groove of the trapezoidal elastic card. The positioning slider 6 is upgraded to a metal material with surface hardening treatment and increased thickness. The fixing bolt 11 is replaced with a high-strength bolt to improve the connection strength.

[0024] During off-road driving, frequent bumps and impacts are common. The wedge-shaped structure of the trapezoidal elastic card effectively prevents the wheel cover from loosening and shifting. The reinforced positioning slider and high-strength bolts ensure the stability of the overall structure. Even in extreme road conditions, the wheel cover can firmly fit the tire, reducing the risk of falling off.

[0025] Off-road scenario effect: Suitable for off-road races, wilderness exploration and other scenarios, ensuring the reliability of wheel covers under high-intensity use and improving vehicle protection performance.

[0026] Furthermore, when using this device, when it is necessary to install the car wheel cover 1, first install the positioning slider 6 in the corresponding groove on the inner wall of the rear end of the car wheel cover 1 using the fixing bolt 11, so that the positioning slider 6 and the car wheel cover 1 are connected as a whole. At this time, the elastic element 8 (whether it is an arc-shaped elastic card or a trapezoidal elastic card 10) is partially located outside the elastic card mounting groove 4 under its own elastic action. Align the car wheel cover 1 with the installation position, so that the positioning slider 6 is aligned with the positioning slider groove 3 on the mounting base 2. Then push the car wheel cover 1, causing the positioning slider 6 to slide along the positioning slider groove 3. During the sliding process, the edge of the elastic card limiting groove 9 or the trapezoidal elastic card limiting groove on the mounting base 2 will squeeze the elastic element 8, causing the elastic element 8 to undergo elastic deformation. It will contract along the fixing rod 5 through the groove 7 into the elastic card mounting groove 4, thereby allowing the positioning slider 6 to continue to slide. When the positioning slider 6 slides to the appropriate position, that is, when the position of the elastic element 8 corresponds to the position of the elastic card limiting groove 9 or the trapezoidal elastic card limiting groove, the compression of the elastic element 8 will be reduced. When the force disappears, the wheel cover returns to its original shape under its own elasticity. Its arc-shaped or trapezoidal outer wall will be inserted into the corresponding elastic card limiting groove 9 or trapezoidal elastic card limiting groove. At this time, the elastic element 8 cooperates with the limiting groove to restrict the sliding of the positioning slider 6 in the positioning slider groove 3, thereby fixing the car wheel cover 1 in the installation position and completing the installation process. Then, when it is necessary to remove the car wheel cover 1, pull the car wheel cover 1 in the removal direction, and drive the positioning slider 6 to slide in the opposite direction along the positioning slider groove 3. At this time, the edge of the elastic card limiting groove 9 or trapezoidal elastic card limiting groove will squeeze the elastic element 8 again, causing the elastic element 8 to undergo elastic deformation and contract into the elastic card mounting groove 4, disengaging from the limiting groove. As the positioning slider 6 continues to slide, when the positioning slider 6 completely slides out of the positioning slider groove 3, the car wheel cover 1 separates from the mounting seat 2, completing the disassembly process. The whole process uses the elastic deformation of the elastic element 8 to lock and unlock the positioning slider 6 and the mounting seat 2. No additional tools are needed, the operation is convenient, and the car wheel cover 1 can be quickly disassembled and installed.

[0027] By using the elastic element 8 (arc-shaped elastic card or trapezoidal elastic card 10) in the elastic buckle assembly with the elastic card limiting groove 9, a "tool-free" operation is achieved. During installation, simply push the car wheel cover 1 so that the positioning slider 6 slides along the positioning slider groove 3 of the mounting base 2. The elastic element 8 automatically deforms under pressure and snaps into the limiting groove to complete the fixation. During disassembly, simply pull the wheel cover in the opposite direction. The elastic element 8 is squeezed and contracted by the edge of the limiting groove to disengage, and the positioning slider 6 slides out of the groove to complete the separation. The whole process does not require tool assistance, which greatly improves the operational efficiency of vehicle maintenance, wheel cover replacement or cleaning, and is especially suitable for scenarios such as quick repair.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
