[0009] According to some embodiments of this utility model, the buckle portion is rectangular, and the shape and size of the snap-fit ​​hole are adapted to the shape and size of the buckle portion.

[0010] According to some embodiments of the present invention, a reinforcing rib is provided on the side of the upper cover away from the base, and the reinforcing rib extends along the length direction of the upper cover.

[0011] According to some embodiments of the present invention, one end of the upper cover is hinged to the base, and the other end is snapped together with the base.

[0012] According to some embodiments of this utility model, one end of the upper cover is provided with an upper hook, and one end of the base is provided with a lower hook corresponding to the upper hook, and the lower hook and the upper hook can be fixed to each other.

[0033] Reference Figures 1 to 5As shown, an embodiment of the present invention provides a high-voltage wiring harness fixing clip for electric motorcycles, comprising: a base 100, a top cover 300, a buckle portion 400, and an elastic element 600. The base 100 has a wiring harness fixing hole 110, through which a corrugated tube 200 passes. The size of the wiring harness fixing hole 110 is larger than the size of the corrugated tube 200 to facilitate the installation of the corrugated tube 200 into the wiring harness fixing hole 110. The corrugated tube 200 is used for the high-voltage wiring harness of the vehicle to pass through, and the corrugated tube 200 protects the wiring harness from damage caused by external forces. The top cover 300 is detachably connected to the base 100, and both the top cover 300 and the base 100 are made of plastic. The upper cover 300 is used to fix the bellows 200 inside the wire harness fixing hole 110; the upper cover 300 applies pressure to the bellows 200 radially, so that the bellows 200 is tightly abutted against the inner wall of the wire harness fixing hole 110. A snap-fit ​​part 400 is located on the side of the base 100 away from the upper cover 300, and the snap-fit ​​part 400 is snap-fitted into the snap-fit ​​hole 510 on the vehicle body 500; the base 100 is detachably connected to the vehicle body 500 through the snap-fit ​​part 400, facilitating later maintenance. An elastic element 600 is located on the side of the base 100 away from the upper cover 300, and the elastic element 600 is used to drive the base 100 away from the vehicle body 500. The elastic element 600 is an obliquely extending plastic sheet connected to the base 100, and the elastic element 600 is integrally formed with the base 100. During the installation of the base 100 onto the vehicle body 500, the elastic element 600 is deformed by the vehicle body 500, thus adhering tightly to the base 100. The elastic element 600, relying on its own elasticity, deforms to push the base 100 away from the vehicle body 500. It is foreseeable that multiple clips 400 and elastic elements 600 are provided to ensure a more stable fixation of the base 100. The upper cover 300, which clips onto the base 100, facilitates the fixation of the corrugated pipe 200 to the base 100. After the base 100 is clipped onto the vehicle body 500, it is prone to wobbling, causing unstable wiring harness fixation, resulting in rattling noises or loosening during vehicle operation. The elastic element 600, by applying elastic force to the base 100, prevents the base 100 from wobbling, making the fixation between the base 100 and the vehicle body 500 more secure and preventing the base 100 from falling off during vehicle vibration.

[0034] Reference Figure 1 and Figure 4 As shown, it can be understood that there are three wire harness fixing holes 110 spaced apart. The number of wire harness fixing holes 110 is determined by the number of corrugated pipes 200 that need to be fixed. In this embodiment, there are three corrugated pipes 200 that need to be fixed, so three wire harness fixing holes 110 are provided. It is foreseeable that when the number of wire harness fixing holes 110 exceeds three, the number of snap-fit ​​parts 400 needs to be increased to ensure the reliability of the base 100 fixing.

[0035] Reference Figure 3 and Figure 5As shown, the upper cover 300 has an arc-shaped groove 310, the shape of which matches the bellows 200. A portion of the bellows 200 is embedded in the arc-shaped groove 310. The upper cover 300 is designed with an arc-shaped groove 310 structure that matches the contour of the bellows 200. By partially fitting the bellows 200 into the groove, a precise curved surface fit is formed at the contact interface. The function of the arc-shaped groove 310 is to increase the contact area between the upper cover 300 and the bellows 200, preventing damage to the bellows 200 when the upper cover 300 presses against it. This design effectively increases the contact area between the upper cover 300 and the bellows 200, allowing the clamping force to be evenly distributed across the curved contact area, thus forming a buffer protection mechanism. This ensures the bellows 200 is securely fixed and avoids surface damage to the bellows 200 caused by stress concentration.

[0036] Reference Figure 4 As shown, it can be understood that a raised rib 111 is arranged around the wire harness fixing hole 110, and the raised rib 111 is used to prevent the axial movement of the bellows 200. The raised rib 111 is integrally injection molded with the base 100, and the height of the raised rib 111 protruding from the wire harness fixing hole 110 is the same as the depth of the groove on the bellows 200. The raised rib 111 can be embedded in the groove on the bellows 200 to prevent the bellows 200 from moving axially. It is foreseeable that the arc-shaped groove 310 of the upper cover 300 is also provided with a raised rib 111 to help limit the position of the bellows 200.

[0037] Reference Figure 2 and Figure 4 As shown, the snap-fit ​​part 400 adopts a rectangular structure design, and the snap-fit ​​hole 510 is also rectangular. The shape and size of the snap-fit ​​hole 510 are adapted to the shape and size of the snap-fit ​​part 400. After the snap-fit ​​part 400 is precisely embedded in the snap-fit ​​hole 510, the rectangular contours of the two form a circumferential limiting constraint, effectively suppressing relative rotational movement and ensuring that the wire harness and the bellows 200 maintain the correct orientation. It is foreseeable that when there are two or more snap-fit ​​parts 400, the specific snap-fit ​​connection structure between the snap-fit ​​part 400 and the snap-fit ​​interface is existing technology and will not be described in detail. The cross-sectional shape of the snap-fit ​​part 400 can be extended to a circular shape or maintain a rectangular design. Both geometric shapes can achieve torque balance through symmetrically distributed multiple snap-fit ​​points, achieving the same anti-rotation effect. This design strategy ensures assembly reliability and provides flexible structural selection space for engineering applications.

[0038] Reference Figure 5As shown, it can be understood that a reinforcing rib 320 is provided on the surface of the upper cover 300 away from the base 100, and the reinforcing rib 320 extends along the length of the upper cover 300. The reinforcing rib 320 forms an integral structure with the main body of the upper cover 300 through an integrated injection molding process. Based on the lightweight design concept, this longitudinal reinforcing rib 320 layout effectively controls the weight of the component while significantly improving the bending stiffness of the upper cover 300 along its long axis. This structural reinforcement design enables the upper cover 300 to maintain excellent structural stability when bearing the assembly load of the bellows 200, effectively suppressing deformation caused by external forces, thereby ensuring that the bellows 200 can obtain reliable positioning and holding force after installation, maintaining the stability of the overall system structure.

[0039] Reference Figure 3 and Figure 4 As shown, it can be understood that one end of the upper cover 300 is hinged to the base 100, and the other end of the upper cover 300 is mounted on one end of the base 100 via a pivot. It is foreseeable that the connection between the upper cover 300 and the base 100 could also be a bolt connection. The advantage of a snap-fit ​​connection is ease of assembly and disassembly, but its connection strength is not as good as a bolt connection. Therefore, the choice can be made based on the actual situation. To reduce manufacturing costs, the base 100 and the upper cover 300 can be integrally injection molded, with one end of the upper cover 300 and one end of the base 100 connected by a flexible bending section with a thickness of 0.8-1.2mm to achieve a hinged connection.

[0040] Reference Figure 3 and Figure 5 As shown, it can be understood that the upper cover 300 has an upper hook 330 at one end, and the upper cover 300 and the upper hook 330 are integrally injection molded. The base 100 has a lower hook 120 at one end corresponding to the upper hook 330, and the lower hook 120 and the base 100 are integrally injection molded. The lower hook 120 and the upper hook 330 can be fixed to each other. The upper cover 300 and the base 100 are connected by the upper hook 330 and the lower hook 120, which has the advantage of convenient installation.

[0041] Reference Figure 3 As shown, it can be understood that the upper end of the lower hook 120 is connected to the unlocking part 121, and the upper end of the unlocking part 121 is provided with an inclined surface to facilitate the separation of the lower hook 120 and the upper hook 330. During disassembly, simply move the unlocking part 121 away from the base 100 to move the lower hook 120 away from the upper hook 330. No other tools are required for disassembly, which has the advantage of convenient disassembly and installation.

[0042] Reference Figure 4As shown, it can be understood that the base 100 has weight-reducing holes 130. The position of the weight-reducing holes 130 can be flexibly arranged. The function of the weight-reducing holes 130 is to reduce the weight of the base 100 while maintaining the structural strength of the base 100, thereby reducing the overall weight of the vehicle.

[0043] Installation steps: Connect the latching part 400 on the base 100 to the latching hole 510 on the body 500. After the latching part 400 is inserted into the latching hole 510, the rectangular outlines of the two form a circumferential limiting constraint, effectively suppressing the relative rotational movement of the base 100 and ensuring that the wire harness and the bellows 200 maintain the correct orientation. Then, pass the wire harness through the bellows 200 and place the bellows 200 into the wire harness fixing hole 110. Rotate the top cover 300 to latch it onto the base 100. The top cover 300 presses the bellows 200 tightly into the wire harness fixing hole 110. The protruding rib 111 is embedded in the groove on the bellows 200, preventing the axial movement of the bellows 200.

[0044] 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.
