[0020] As shown in the figure, the utility model provides a headlight harness fixing buckle, comprising a buckle body arranged on the headlight housing, the buckle body comprising a base 2 and a bent portion 3 arranged on the base 2, the bent portion 3 is connected to the base 2 at one end in the height direction, and the bent portion 3 is bent with a single degree of freedom in any direction parallel to the top surface of the base 2 at the other end in the height direction and forms a C-shaped slot 6 for fixing the headlight harness between the top surface of the base 2, and a limiting structure for preventing the headlight harness from turning outward is arranged at the opening of the C-shaped slot 6; wherein the buckle body is an injection molded part, and since the injection molded part has good elasticity, the headlight harness is easier to assemble into the buckle body, and at the same time, the buckle body can be integrated on the vehicle body housing and manufactured together with the headlight housing, which is also It can be a separate structure and installed on the headlight housing 1 through the base 2, and the specific selection is made according to the headlight design; and a C-shaped slot 6 for fixing the headlight wiring harness 1 is formed in the space between the base 2 and the curved portion 3. The C-shaped slot 6 has an opening and the headlight wiring harness 1 is assembled through the opening. Although the C-shaped slot 6 has a certain restraining force and can play a certain fixing role on the headlight wiring harness 1, it is inevitable to encounter bumpy sections during the driving process of the vehicle. Therefore, in order to prevent the headlight wiring harness 1 from falling off the C-shaped slot 6 and affecting the operation of the headlight, a limiting structure for preventing the headlight wiring harness from turning outward is provided at the opening of the C-shaped slot 6. The limiting structure can be a limiting column, a limiting rib or a cover structure for opening and closing the opening, and it can be selected according to the internal space of the headlight housing and the usage.

[0021] In this embodiment, the limiting structure includes a first anti-slip rib 4 provided at the opening of the C-shaped slot 6 and a second anti-slip rib 5 provided at the opening of the C-shaped slot 6 by the base, and the straight-line distance between the first anti-slip rib 4 and the second anti-slip rib 5 in the vertical direction is less than the diameter of the headlight harness 1; Figure 1 As shown, by respectively providing a first anti-slip rib 4 on the base and a second anti-slip rib 5 on the bending portion 3, a plurality of limit positions are formed in the length direction of the headlight wiring harness 1, and the first anti-slip rib 4 and the second anti-slip rib 5 cooperate to hold the headlight wiring harness 1 to prevent the headlight wiring harness 1 from slipping and displacing.

[0022] In this embodiment, the base 2 is provided with a through hole 7 in the vertical direction, and the cross-sectional dimension of the through hole 7 in the vertical direction is larger than the projection dimension of the curved portion 3 on the base 2; Figure 1 and Figure 4As shown, since the buckle body is an injection molded part, and the gap between the base 2 and the bent portion 3 is small, demoulding difficulties and poor molding quality of the bent portion are likely to occur during the injection molding process, thereby affecting the molding quality and fixed structural strength of the buckle body. Therefore, a through hole 7 is opened on the base 2 so that the molding mold core of the bent portion 3 can be demoulded through the through hole 7, which not only ensures the molding quality but also makes demoulding easier; at the same time, the provision of the through hole 7 also reduces the overall weight of the buckle body and reduces the use of molding materials.

[0023] In this embodiment, the first anti-channeling ribs 4 are respectively provided on both sides of the through hole 7 along the length direction of the vehicle light harness 1 and are formed by the base 2 protruding vertically upwards; Figure 1 and Figure 2 As shown, in the present embodiment, there are two first anti-slip ribs 4, which are respectively provided with through holes 7 on both sides along the length direction of the headlight wiring harness 1, namely, on the left and right sides of the bending portion. By respectively providing the first anti-slip ribs 4 on the left and right sides of the bending portion to cooperate with the second anti-slip ribs 5, a multi-section limit is formed in the length direction of the headlight wiring harness 1 to prevent the headlight wiring harness 1 from slipping and displacement.

[0024] In this embodiment, the second anti-slip rib 5 is formed by the bending portion 3 protruding vertically downward at the opening of the C-shaped slot 6, and the horizontal tangent height of the second anti-slip rib 5 at the lowest point in the vertical direction needs to be lower than the center point height of the headlight harness 1; Figure 1 and Figure 3 As shown, by designing the horizontal tangent height of the second anti-slip rib 5 at the lowest point in the vertical direction to be lower than the center point height of the headlight harness 1, the headlight harness 1 can be effectively prevented from falling off or slipping out of the C-shaped slot 6 during vehicle driving.

[0025] In this embodiment, the rib thickness of the second anti-swiping rib 5 needs to be less than 0.5 times the wall thickness of the bending portion 3; by designing the rib thickness of the second anti-swiping rib 5 to be less than 0.5 times the wall thickness of the bending portion 3, the same manufacturing specification is formed, and the second anti-swiping rib 5 is easier to form on the bending portion 3.

[0026] In this embodiment, the bent portion 3 is recessed inwardly at the back side away from the vehicle light harness 1 and forms a weight-reducing groove 8; Figure 3 and Figure 4 As shown, by providing a weight-reducing groove 8 on the back side of the bending portion 3, the overall weight of the buckle body is reduced and the use of molding materials is reduced while ensuring the function of the bending portion 3; at the same time, by providing the weight-reducing groove 8, the wall thickness of the bending portion can be made uniform, so as to reduce defects occurring during the molding process of the bending portion.

[0027] In this embodiment, the buckle body is made of one-piece injection molding; the buckle body can be a separate structure and is made of one-piece injection molding, or it can be made of the structure of the headlight shell and the headlight shell by one-piece injection molding; by adopting the one-piece injection molding process, it is easier to obtain the buckle body structure in this solution, and the buckle body made of plastic material has good elasticity and a long service life.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
