[0006] Furthermore, a fourth mounting plate is provided on the side of the first mounting plate that is relatively far away from the second and third mounting plates, transitioning downwards. The fourth mounting plate is provided with waist-shaped fastener fixing holes.

[0007] Furthermore, the second mounting plate is provided with an L-shaped protrusion, which forms a wire harness fixing groove with the inclined surface of the second mounting plate, and cable tie through holes are provided on both sides of the bottom of the wire harness fixing groove.

[0008] Furthermore, a vertical plate is provided on the side of the third mounting plate away from the first mounting plate, and the vertical plate has cable tie fixing holes.

[0009] In summary, the present invention has the following beneficial effects: In this application, by setting a first mounting plate, a second mounting plate, a third mounting plate, as well as mounting holes, a plug-in fixing structure, plug-in fixing holes and wire harness clip fixing holes, multiple inline connectors and wire harnesses can be fixed on the entire fixing bracket, resulting in high integration and greatly improving wiring efficiency.

[0013] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0014] like Figure 1-2 As shown in the illustration, this application discloses a lightweight integrated wire harness fixing bracket, including a first mounting plate 1, a second mounting plate 2, and a third mounting plate 3. The first mounting plate 1, second mounting plate 2, and third mounting plate 3 are integrally injection molded from PA6+GF15 material, reducing cost and weight while meeting safety and strength requirements. The second mounting plate 2 is located on one side of the first mounting plate 1 and is obliquely upward. The third mounting plate 3 is located on the side of the first mounting plate 1 opposite to the second mounting plate 2 and transitions downward, with its surface parallel to the surface of the first mounting plate 1. The front surfaces of the first mounting plate 1, second mounting plate 2, and third mounting plate 3 are smooth, while the back surfaces have several reinforcing ribs, achieving lightweighting while ensuring overall structural strength.

[0015] Mounting holes 4 are provided on the side of the second mounting plate 2 and the third mounting plate 3 away from the first mounting plate 1. The mounting holes 4 are used to connect the fixing bracket to the body panel, specifically by screw connection. Considering the tolerance of the fixing bolts and welding tolerance, the mounting holes 4 on the second mounting plate 2 are designed as circular positioning holes, and the mounting holes 4 on the third mounting plate 3 are designed as semi-open oblong holes. Both mounting holes 4 have metal bushings to facilitate fixing by screw connection.

[0016] Several plug-in fixing structures 5 are provided on the surfaces of the first mounting plate 1 and the second mounting plate 2. The plug-in fixing structures 5 are used to fix the inline connectors. The plug-in fixing structures 5 are snap-fit ​​structures that match the connector slide grooves and are fixed stably by locking structures.

[0017] On the first mounting plate 1, near the plug-in fixing structure 5, there is also a plug-in fixing hole 6. The plug-in fixing hole 6 is an oblong hole used to fix the inline connector. The first mounting plate 1 is also provided with a wire harness clip fixing hole 7. The wire harness clip fixing hole 7 is used to install and fix the clips of the wire harness, and the wire harness is fixed by the clips.

[0018] A fourth mounting plate 8 is provided on the side of the first mounting plate 1 that is relatively far away from the second mounting plate 2 and the third mounting plate 3, transitioning downwards. The fourth mounting plate 8 has a waist-shaped clip fixing hole 9, which is used to install and fix the clips of the wire harness. The waist-shaped hole design makes it easier to constrain the direction of the wire harness.

[0019] An L-shaped protrusion 10 is provided on the second mounting plate 2. The L-shaped protrusion 10 and the inclined surface of the second mounting plate 2 form a wire harness fixing groove 11. Cable tie through holes 12 are provided on both sides of the bottom of the wire harness fixing groove 11. The wire harness fixing groove 11 is used to fix the wire harness and constrain the direction of the wire harness. The cable tie through holes 12 on both sides are designed to bind and fix the wire harness by passing the cable tie through holes 12.

[0020] A vertical plate 13 is provided on the side of the third mounting plate 3 away from the first mounting plate 1. A cable tie fixing hole 14 is provided on the vertical plate 13. This hole can be used to fix the vehicle body wiring harness. The cable tie with rivets is fixed to the wiring harness, and then the rivets are installed into the cable tie fixing hole 14 to fix the vehicle body wiring harness.

[0021] In this embodiment, multiple mounting plates are used to form a fixed bracket structure, and several fixing structures and fixing holes are set to fix and guide the low-voltage wire harnesses such as vehicle body wiring harness, door and window wiring harness, and instrument wiring harness. It has the advantages of reliable fixing, convenient operation, high integration and lightweight.

[0022] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
