Description

Technical Field

[0001] This application relates to the field of automotive wheel arch technology, and more specifically, to an easily detachable wheel arch structure. Background Technology

[0002] Wheel arches are decorative and protective components installed on the edge of the wheel arches of a car. They are usually made of materials such as plastic and rubber. Their main function is to block mud, sand, stones and other debris kicked up by the wheels during driving, reducing the impact and scratches of these debris on the side of the car body, and protecting the paint and sheet metal structure. This protective effect is more obvious when driving on unpaved roads. At the same time, wheel arches can complement the body lines and enhance the overall aesthetics of the car.

[0003] Most existing wheel arch fixing methods use snap-on clips and screws. Snap-on clips are fixed by snapping into the body sheet metal. This method is relatively simple to operate during installation, but once snapped in, the disassembly process is very difficult, and forcibly removing them can easily damage the wheel arch. While screw fixing is more secure, special tools must be used when removing and replacing wheel arches, making the operation cumbersome and causing many inconveniences for users. Therefore, there is an urgent need for an easily detachable wheel arch structure. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, this application provides an easily detachable wheel arch structure, which enables convenient and quick installation and removal of wheel arches, improving installation and removal efficiency and reducing installation and removal difficulty.

[0006] The easily detachable wheel arch structure provided in this application includes a wheel arch body, a slot, a rotating buckle, and a positioning pin. The slot extends through the wheel arch body and is adapted to a corresponding mounting position on the vehicle body. The rotating buckle is fitted into the slot of the wheel arch body, and the rotating buckle, adapted to the slot, can rotate along a preset trajectory within the slot to achieve fastening and loosening with the vehicle body. The positioning pin protrudes from the side of the wheel arch facing the vehicle body and is used to engage with a positioning hole on the vehicle body during the pre-installation stage of the wheel arch.

[0007] In some embodiments, the rotating buckle includes: a rotating shaft rotatably inserted into the slot; a handle disposed at one end of the rotating shaft; two first locking blocks symmetrically protruding from the outer periphery of the end of the rotating shaft away from the handle; and two second locking blocks symmetrically protruding from the outer periphery of the rotating shaft and the two first locking blocks opposite to each other in the circumferential direction.

[0008] In some embodiments, the slot includes: two first slots formed on the wheel arch body; and two second slots formed on the wheel arch body and the two first slots on opposite sides in the circumferential direction.

[0009] In some embodiments, the two first slots are for receiving the corresponding first card blocks and are movable when rotating with the rotation axis, and the two second slots are for receiving the corresponding second card blocks and are movable when rotating with the rotation axis.

[0010] In some embodiments, the first card block has a wedge-shaped surface.

[0011] In some embodiments, the locating pin is X-shaped.

[0012] Compared with the prior art, the technical solution provided in this application includes at least the following technical effects: This application provides an easily detachable wheel arch structure that facilitates convenient and quick installation and removal of wheel arches, improving efficiency and reducing difficulty. With the wheel arch body facing the vehicle body, align the locating pin with the locating hole on the vehicle body and insert it. The engagement of the locating pin and the locating hole quickly determines the installation position of the wheel arch. At this point, the wheel arch body initially fits against the vehicle body, and the slot aligns with the locking structure of the vehicle body mounting position. Manually rotate the rotating buckle embedded in the slot, causing it to rotate along the preset track of the slot. This gradually engages the rotating buckle with the corresponding locking structure of the vehicle body mounting position. Through the friction and limiting effect between the structures, the wheel arch body is firmly fixed to the vehicle body. When it is necessary to remove the wheel arch, rotate the rotating buckle in the opposite direction, causing it to move in the opposite direction along the track of the slot, gradually disengaging from the vehicle body and releasing the fastening, allowing the wheel arch to be removed. In this design, the rotation of the rotating buckle can be completed manually without special tools, solving the problems of traditional screw fixing requiring tools and difficult removal of buckles by pressing, thus lowering the threshold for installation and removal.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0018] The following reference Figures 1 to 6 This application describes an easily detachable wheel arch structure provided according to some embodiments.

[0019] like Figures 1 to 6 As shown, an easily detachable wheel arch structure according to some embodiments of this application includes a wheel arch body 1, a slot 3, a rotating buckle 2, and a positioning pin 4. The slot 3 is formed through the wheel arch body 1 and is adapted to a corresponding mounting position on the vehicle body 5. The rotating buckle 2 is fitted into the slot 3 of the wheel arch body 1, and the rotating buckle 2 is adapted to the slot 3, rotating along a preset trajectory within the slot 3 to achieve fastening and loosening with the vehicle body 5. The positioning pin 4 protrudes from the side of the wheel arch facing the vehicle body 5 and is used to engage with a positioning hole on the vehicle body 5 during the pre-installation stage of the wheel arch.

[0020] In this embodiment, the wheel arch body 1 is oriented towards the vehicle body 5, and the positioning pin 4 is aligned with and inserted into the positioning hole of the vehicle body 5. The installation position of the wheel arch is quickly determined by the cooperation between the positioning pin 4 and the positioning hole. At this time, the wheel arch body 1 initially fits against the vehicle body 5, and the slot 3 is aligned with the snap-fit ​​structure of the installation position of the vehicle body 5. The rotating buckle 2, which is embedded in the slot 3, is manually rotated so that it rotates along the preset trajectory of the slot 3, so that the rotating buckle 2 gradually engages with the snap-fit ​​structure of the corresponding installation position of the vehicle body 5. Through the friction and limiting effect between the structures, the wheel arch body 1 is firmly fixed to the vehicle body 5. When it is necessary to remove the wheel arch, the rotating buckle 2 is rotated in the opposite direction so that it moves in the opposite direction along the trajectory of the slot 3, gradually disengaging from the vehicle body 5 and releasing the fastening state, so that the wheel arch can be removed.

[0021] In this design, the rotation of the rotating buckle 2 can be completed manually without special tools, which solves the problems of traditional screw fixing requiring tools and the difficulty of disassembling the buckle by pressing, thus lowering the threshold for disassembly and assembly.

[0022] In some possible embodiments, such as Figures 2 to 6 As shown, the rotating buckle 2 includes: a rotating shaft 22, which is rotatably inserted into the slot 3; a handle 21, which is disposed at one end of the rotating shaft 22; two first locking blocks 23, which are symmetrically protruding from the outer periphery of the end of the rotating shaft 22 away from the handle 21; and two second locking blocks 24, which are symmetrically protruding from the outer periphery of the rotating shaft 22 and the two first locking blocks 23 opposite to each other in the circumferential direction; the slot 3 includes: two first locking slots 31, which are formed on the wheel arch body 1; and two second locking slots 32, which are formed on the two sides of the wheel arch body 1 opposite to each other in the circumferential direction.

[0023] In this embodiment, after the wheel arch body 1 is pre-positioned by the positioning pin 4, the first locking block 23 and the second locking block 2 of the rotating buckle 2 are aligned with the locking structure of the corresponding mounting position of the body 5. At this time, the first locking groove 31 and the second locking groove 32 are aligned with the mounting position of the body 5. By holding handle 21 and rotating the rotating shaft 22 clockwise, the rotating shaft 22 drives the first locking block 23 and the second locking block 24 to rotate synchronously, rotating along the preset trajectory in the first locking groove 31 and the second locking groove 32. As the rotating buckle 2 rotates, the first locking block 23 and the second locking block 24 gradually embed into the corresponding locking structure of the body 5. Through the interaction of the wedge-shaped surfaces, a locking force is generated, which fastens the wheel arch to the body 5. When the first locking block 23 and the second locking block 24 rotate to the end position of the first locking groove 31 and the second locking groove 32, the wheel arch and the body 5 are firmly connected and the installation is completed. When removing the wheel arch, by rotating handle 21 counterclockwise, the first locking block 23 and the second locking block 24 gradually disengage from the corresponding locking structure of the body 5, and the connection force between the wheel arch and the body 5 disappears.

[0024] In some possible embodiments, such as Figure 2 , Figure 6As shown, the two first slots 31 are for accommodating the corresponding first card block 23 and move when rotating with the rotating shaft 22, and the two second slots 32 are for accommodating the corresponding second card block 24 and move when rotating with the rotating shaft 22.

[0025] In this embodiment, the first slot 31 and the second slot 32 provide a clear movement trajectory for the corresponding first block 23 and second block 24. When the wheel arch is installed, the blocks can only move along the path set by the slot 3, which ensures that the blocks can accurately engage with the corresponding mounting position of the vehicle body 5, thereby improving the installation accuracy.

[0026] In some possible embodiments, the first card block 23 has a wedge-shaped surface.

[0027] In this embodiment, the first locking block 23 is designed with a wedge-shaped surface, which is mainly used to form a tight fit with the locking structure of the corresponding mounting position of the vehicle body 5. The interaction of the wedge-shaped surfaces generates a large locking force, which firmly fixes the wheel arch to the vehicle body 5, preventing the wheel arch from loosening or falling off during vehicle operation.

[0028] In some possible embodiments, such as Figure 4 As shown, the locating pin 4 is X-shaped.

[0029] In this embodiment, the X-shaped locating pin 4 has multiple contact points, which, compared with the traditional circular locating pin, can restrict the movement freedom of the part in more directions and better restrict the rotational freedom, thereby improving the positioning accuracy.

[0030] During operation of this easily detachable wheel arch structure, the wheel arch body 1 is oriented towards the vehicle body 5, and the locating pin 4 is aligned with and inserted into the locating hole of the vehicle body 5. Since the locating pin 4 is X-shaped and has multiple contact points, it can restrict the movement freedom of the wheel arch body 1 in more directions when engaging with the locating hole of the vehicle body 5, thus quickly determining the installation position of the wheel arch. At this point, the wheel arch body 1 initially fits against the vehicle body 5, and the slot 3 is also aligned with the snap-fit ​​structure of the installation position on the vehicle body 5. Then, the rotating buckle 2, fitted into the slot 3 of the wheel arch body 1, is aligned with the snap-fit ​​structure of the corresponding installation position on the vehicle body 5 using its first snap-fit ​​block 23 and second snap-fit ​​block 24. Holding the handle 21, the rotating shaft 22 is rotated clockwise. The rotating shaft 22 drives the first snap-fit ​​block 23 and the second snap-fit ​​block 24 to rotate synchronously, moving them along the first slot 31. As the second slot 32 rotates along its preset trajectory, the first locking block 23 and the second locking block 24 gradually embed into the corresponding locking structure of the body 5. Through the interaction between the wedge-shaped surface of the first locking block 23 and the locking structure of the corresponding installation position of the body 5, a large locking force is generated. When the first locking block 23 and the second locking block 24 rotate to the end positions of the first slot 31 and the second slot 32, the wheel arch and the body 5 are firmly connected, and the installation is completed. When it is necessary to remove the wheel arch, by rotating the handle 21 counterclockwise, the rotating shaft 22 drives the first locking block 23 and the second locking block 24 to move in the opposite direction along the trajectory of the slot 3. The locking blocks of the rotating buckle 2 gradually disengage from the locking structure of the body 5, the connection force between the wheel arch and the body 5 disappears, and the engagement with the body 5 is gradually released, thus releasing the fastening state and allowing the wheel arch to be removed.
