[0030] Before describing the embodiment of the utility model in detail, the application environment of the utility model is described first. The technology of the utility model is mainly applied to the field of vehicle manufacturing technology. The utility model is used to solve the problem that the existing automobile wiring harness fixing device has high processing cost and long manufacturing cycle when processing threaded holes on the body.

[0031] Please combine Figures 1 to 7 As shown, the utility model provides an automobile wiring harness fixing structure and a vehicle.

[0032] In an exemplary embodiment of the present application, an automobile wiring harness fixing structure includes: a mounting component, which is arranged on the body structure of the automobile; a fixing seat 1, which is provided with a guide groove 101, and the guide groove 101 is used to guide the fixing seat 1 to be installed on the mounting component, and the fixing seat 1 is provided with at least one fixing position for fixing the wiring harness; at least one locking component 2, which is distributed on the fixing seat 1 along the axial direction of the guide groove 101, and the locking component 2 includes a locking portion 201, and the locking portion 201 is located in the guide groove 101, and the locking portion 201 is interference fit with the mounting component.

[0033] In this embodiment, the mounting component is a positioning column set on the vehicle body structure for positioning and mounting the fixing seat 1. The existing harness fixture is to process a threaded hole on the positioning column, and then fix the harness through a combination of a sheet metal structure and a rubber sleeve. First, processing a threaded hole on the positioning column will increase the processing cost and the manufacturing cycle will be longer; second, the development cost of the sheet metal and the rubber sleeve itself is high, and the weight is large. The sheet metal and the rubber sleeve are used in many places of the vehicle to fix the harness, which is not conducive to the lightweight of the vehicle. However, the present application uses the guide groove 101 set on the fixing seat 1 to guide the installation of the mounting component set on the vehicle body structure, and the locking component 2 set on the fixing seat 1 is interference-fitted with the mounting component, so as to effectively prevent the fixing seat 1 from falling off from the mounting component, and realize the stable connection between the fixing seat 1 and the vehicle body structure; because the fixing seat 1 is provided with a fixing position for fixing the harness, the connection between the vehicle harness and the fixing seat 1 is realized by fixing the vehicle harness in the fixing position, so that the harness can be fixed to the vehicle body, reducing the influence of the vehicle vibration on the connection between the harness and the harness connector, and avoiding poor contact or falling off of the harness and the harness connector. By adopting the technical solution of the present application, there is no need to process threaded holes on the vehicle body structure, and the connection between the fixing seat 1 and the vehicle body structure is achieved by using the interference fit between the locking component 2 and the mounting component, which effectively reduces the processing cost and shortens the manufacturing cycle. The fixing seat 1 shown in this embodiment is made of plastic material, and the locking component 2 is made of metal material, such as stainless steel. The locking component 2 and the fixing seat 1 are formed into an integrated structure through an integrated injection molding process, which has a low manufacturing cost and is easy to install. The plastic material is light in weight, which ensures the structural strength while being conducive to achieving the lightweight effect of the entire vehicle.

[0034] It is worth noting that the automobile wiring harness fixing structure shown in the embodiment of the present application is symmetrically provided with two fixing positions along the radial direction of the guide groove 101 , and two locking components 2 are provided along the axial direction of the guide groove 101 .

[0035] In an exemplary embodiment of the present application, the locking component 2 is provided with a locking hole 202 coaxially with the guide groove 101 along the thickness direction, and the locking portion 201 is arranged along the circumference of the locking hole 202. The locking portion 201 protrudes axially along the guide groove 101 and protrudes radially along the guide groove 101.

[0036] In the present embodiment, the positioning column is used to cooperate with the guide groove 101 of the wiring harness fixing structure, and the installation part includes but is not limited to being die-cast as a rectangular or circular structure with a cross-section. In the present embodiment, the positioning column is die-cast as a rectangular parallelepiped structure with a rectangular cross-section. The opening shape of the locking hole 202 includes but is not limited to being set as a rectangular hole or a circular hole according to the structural shape of the positioning column. In the present embodiment, the locking hole 202 is opened as a rectangular hole; the locking part 201 is designed to protrude radially along the guide groove 101, so that the locking component 2 can form an interference fit with the installation component. The locking part 201 is set as an axial protrusion along the guide groove 101, which effectively increases the contact area between the locking component 2 and the installation component, increases the connection strength between the fixing seat 1 and the installation component, and reduces the risk of falling off between the wiring harness fixing structure and the installation component.

[0037] In an exemplary embodiment of the present application, the locking portion 201 includes a plurality of burrs 201 a distributed circumferentially along the locking hole 202 , and an angle α between the burrs 201 a and a horizontal plane is an acute angle.

[0038] In this embodiment, a plurality of burr 201a structures are evenly arranged along the long side of the locking hole 202, and the angle α between the burr 201a structure and the shorter side of the locking hole 202 is between 40° and 70°, including but not limited to 45°, 55°, 65°, etc., so that the burr 201a structure and the locking component 2 are arranged at an angle, that is, the locking portion 201 protrudes radially along the guide groove 101. The locking portion 201 is a plurality of burr 201a structures arranged at an angle, and the tip of the burr 201a structure satisfies the interference fit with the mounting component, and can reduce the contact area between the locking portion 201 and the mounting portion, effectively reducing the resistance in the assembly process of the wiring harness fixing structure and the mounting component, so that the assembly of the wiring harness fixing structure and the mounting component can be completed quickly and conveniently. Furthermore, since a barb structure is formed between the inclined burr 201a structure and the mounting component, the burr 201a structure is made of stainless steel, and the mounting component is made of aluminum alloy, a small amount of the burr 201a structure of the locking component 2 will be embedded in the mounting component, further preventing the wiring harness fixing structure from falling off from the mounting component.

[0039] In an exemplary embodiment of the present application, the locking component 2 further includes a planar connection portion 203 and a flanged connection portion 204 , and both the planar connection portion 203 and the flanged connection portion 204 are used to connect to the fixing seat 1 .

[0042] In this embodiment, by setting a threading channel 102 for threading the cable tie 3 at the fixed position, the connection process of the wire harness and the fixing seat 1 is: pass the cable tie 3 through the threading channel 102, and tighten the wire harness in the fixed position by the cable tie 3, thereby completing the connection between the wire harness and the wire harness fixing seat 1.

[0043] In an exemplary embodiment of the present application, the fixing seat 1 is provided with a bearing surface 103 at the fixing position, and the bearing surface 103 is used for bearing the wire harness.

[0044] In this embodiment, the bearing surface 103 is used to bear the wiring harness, the passage 102 is located below the bearing surface 103, the wiring harness is placed above the bearing surface 103, and the wiring harness is fixed to the bearing surface 103 by passing the cable tie 3 through the passage 102, thereby connecting the wiring harness to the fixing seat 1.

[0045] In an exemplary embodiment of the present application, the bearing surface 103 is an arc-shaped surface, and the opening track of the penetrating channel 102 extends along the circumference of the arc-shaped surface.

[0046] In this embodiment, the bearing surface 103 is designed as an arc surface, which is adapted to the circular outer surface design of the wire harness, so that the wire harness can be carried along, and the force between the wire harness and the bearing surface 103 is uniform when the cable tie 3 is tied.

[0047] In an exemplary embodiment of the present application, at least one anti-slip portion 103 a is disposed on the bearing surface 103 , and the anti-slip portion 103 a protrudes along the radial direction of the bearing surface 103 .

[0048] In this embodiment, the anti-skid portion 103a provided on the bearing surface 103 can effectively prevent the relative rotation between the wire harness and the arc-shaped bearing surface 103, thereby avoiding the wear of the wire harness due to the rotation, and ensuring the stability and safety of the wire harness. It is worth noting that an anti-skid portion 103a is provided on the bearing surface 103 shown in the embodiment of the present application.

[0049] In an exemplary embodiment of the present application, the fixing seat 1 is a plastic part, the locking component 2 is a metal part, and the locking component 2 and the fixing seat 1 are integrally formed by injection molding.

[0050] In this embodiment, the metal locking component 2 and the plastic fixing seat 1 are integrally formed by injection molding, which can ensure the close connection between the locking component 2 and the fixing seat 1, thereby improving the overall structural stability of the wiring harness fixing structure; the metal part has high strength and hardness, and can be effectively improved by being integrally formed with the plastic fixing seat 1 by injection molding; and, through integrated injection molding, the number of components and production processes can be reduced, the production process can be simplified, and thus the production cost can be reduced.

Compared with the existing sheet metal bracket and rubber sleeve assembly wiring harness fixer, it has the advantages of low development cost and low weight; through the serrated locking portion 201 set on the locking component 2, the convex thorn 201a structure of the locking portion 201 forms a barb structure on the fixing seat 1, which effectively prevents the wiring harness fixing structure from falling off from the mounting component. The fixing seat 1 is installed by guiding the installation component provided on the vehicle body structure through the guide groove 101. The locking component 2 provided on the fixing seat 1 and the installation component have an interference fit, which can effectively prevent the fixing seat 1 from falling off the installation component, thereby realizing a stable connection between the fixing seat 1 and the vehicle body structure. Since the fixing seat 1 is provided with a fixing position for fixing the wiring harness, the connection between the vehicle wiring harness and the fixing seat 1 is realized by fixing the vehicle wiring harness in the fixing position, thereby fixing the wiring harness to the vehicle body, reducing the influence of the vehicle vibration on the connection between the wiring harness and the wiring harness connector, and avoiding poor contact or falling off between the wiring harness and the wiring harness connector.
