In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] like Figure 1-Figure 3 As shown, this embodiment provides a wire harness holding bracket, which can be used to fix wire harnesses, pipe bundles, etc. on vehicles, electrical cabinets, etc. The wire harness holding bracket includes a first bracket 1 and a second bracket 2 plugged with the first bracket 1, and the second bracket 2 is connected to the fixed wire harness 3.

[0032] like Figure 1 As shown, the first bracket 1 includes a housing 11 and at least three elastic rods 12 located in the housing 11. Both ends of each elastic rod 12 are arranged on the housing 11. All elastic rods 12 are connected end to end in sequence to form a socket 13 between all elastic rods 12. In this embodiment, there are four elastic rods 12 of the same size and material, such as thin steel rods. Figure 3 As shown, the second bracket 2 includes a hollow wiring harness portion 21 for passing the wiring harness and a plug-in post 22 that can be plugged into the socket 13. The plug-in post 22 is arranged on the wiring harness portion 21, and the outer periphery of the plug-in post 22 is reduced in diameter to form a slot 221. When the plug-in post 22 is inserted into the socket 13, each elastic rod 12 is embedded in the slot 221.

[0033] The materials of the first bracket 1 and the second bracket 2 are based on the actual layout environment. In this embodiment, the first bracket 1 and the second bracket 2 are used on a vehicle, and the materials of both can be high-strength plastic or metal. High-strength plastic is light in weight and has a long service life, which can ensure sufficient support force and service life.

[0034] Taking the installation of the fixed wiring harness 3 on the vehicle as an example, the first bracket 1 is fixed on the vehicle in advance, the wiring harness part 21 of the second bracket 2 is put outside the wiring harness, and then the plug 22 of the second bracket 2 is inserted into the socket 13. Through the constraint of the slot 221 on each elastic rod 12, the first bracket 1 and the second bracket 2 are reliably connected and not easy to loosen, so that the wiring harness is reliably fixed on the vehicle; when removing the wiring harness, a certain external force is applied to pull the second bracket 2, so that the elastic rod 12 is elastically deformed and separated from the slot 221, the plug 22 is pulled out from the socket 13, the first bracket 1 is separated from the second bracket 2, and the wiring harness is separated from the vehicle.

[0035] The wire harness holding bracket in this embodiment realizes convenient assembly and disassembly between the first bracket 1 and the second bracket 2 by plugging and unplugging the plug post 22 in the socket 13, and at the same time, each elastic rod 12 is clamped in the clamping groove 221, thereby realizing convenient assembly and disassembly and reuse of the wire harness on the vehicle, and also ensuring the reliable connection between the first bracket 1 and the second bracket 2, so that the wire harness can be reliably fixed on the vehicle. The use of the wire harness holding bracket can quickly and reliably fix and organize the pipe harness inside the vehicle, which can improve production efficiency and reliability of wire harness fixing, can be reused repeatedly, and reduce costs.

[0036] like Figure 3 As shown, optionally, the plug post 22 is located on the side of the slot 221 away from the harness portion 21 and is a spherical portion 222. Along the depth direction of the socket 13, the projection of the spherical portion 222 overlaps with the projection of each elastic rod 12. In other words, the diameter of the spherical portion 222 is slightly larger than the diameter of the socket 13 to prevent the plug post 22 from loosening from the socket 13. When the plug post 22 is inserted into or pulled out of the socket 13, the surface of the spherical portion 222 can provide a guiding effect, which is convenient for disassembly and assembly. Specifically, the plug post 22 also includes a columnar section 223, which is connected between the spherical section 222 and the harness portion 21, and the slot 221 is located between the columnar section 223 and the spherical portion 222. Optionally, the cross-section of the slot 221 along the circumference of the plug post 22 is V-shaped, which can cooperate with the elastic rod 12 to achieve mutual limitation and has a guiding function, so that the elastic rod 12 can slide relative to the slot 221, thereby facilitating the separation of the first bracket 1 and the second bracket 2.

[0037] like Figure 1 As shown, in order to make each elastic rod 12 embedded in the slot 221 , optionally, the elastic rod 12 is an arc rod, and each elastic rod 12 is bent in a direction away from the shell wall of the shell 11 .

[0038] Optionally, a stop groove (not shown) facing the socket 13 is further provided in the housing 11, and the plug post 22 can pass through the socket 13 and be embedded in the stop groove. Specifically, a square protrusion matching the stop groove is provided at one end of the spherical portion 222 away from the columnar section 223, and the cross section of the square protrusion is smaller than the socket 13, and the square protrusion can freely enter and exit the socket 13 and be embedded in the square stop groove, so that the first bracket 1 and the second bracket 2 can be further fixed relative to each other.

[0039] like Figure 3As shown, in this embodiment, the harness portion 21 includes a straight wall 211 and an arc wall 212 arranged opposite to each other. The two ends of the arc wall 212 are closer to the straight wall 211 than the middle part thereof and connected to the straight wall 211. The straight wall 211 and the arc wall 212 are used to pass the harness, and the plug 22 is arranged on the side of the straight wall 211 away from the arc wall 212. In other words, the middle part of the arc wall 212 is farther away from the straight wall 211 than the two ends thereof, thereby forming a depression, so that the fixed harness 3 is kept in this depression.

[0040] like Figure 3 As shown, optionally, the harness portion 21 also includes a first protrusion 213 and a second protrusion 214. The first protrusion 213 is connected to one end of the straight wall 211 in the first direction and one end of the arc wall 212, and the second protrusion 214 is connected to the other end of the straight wall 211 in the first direction and the other end of the arc wall 212. The first protrusion 213 and the second protrusion 214 both extend in the second direction and protrude from the arc wall 212, and the plug 22 extends in the opposite direction of the second direction and protrudes from the straight wall 211, and the second direction is perpendicular to the first direction. By grasping the first protrusion 213 and the second protrusion 214, and plugging and unplugging the plug 22 in the second direction, the second bracket 2 can be fixed on the first bracket 1 or detached from the first bracket 1, which is convenient for operation. The first protrusion 213 and the second protrusion 214 both protrude from the arc wall 212, which can play a certain protective role to prevent other parts or nearby structures from hitting the arc wall 212 and the fixed harness 3.

[0041] In this embodiment, the arc wall 212 is an elastic wall. The relative compression of the first protrusion 213 and the second protrusion 214 can adjust the space between the arc wall 212 and the straight wall 211, so as to facilitate the insertion of the fixed wire harness 3 into the space.

[0042] The first bracket 1 and the vehicle are fixed in any manner, such as Figure 2 As shown, in the present embodiment, the first bracket 1 further includes a columnar portion 14 and a limiting portion 15. The outer shell 11 is disposed at one end of the columnar portion 14, and the limiting portion 15 is detachably disposed at the other end of the columnar portion 14, and the cross-sectional areas of the outer shell 11 and the limiting portion 15 are larger than the cross-sectional area of ​​the columnar portion 14. Specifically, a connecting hole is provided on the structural wall of the vehicle, and the columnar portion 14 is connected to the limiting portion 15 after passing through the connecting hole, and the limiting portion 15 and the outer shell 11 are clamped at the connecting hole of the structural wall to fix the first bracket 1. In the present embodiment, the limiting portion 15 is threadedly connected to the columnar portion 14. It is convenient to disassemble and assemble, and the connection is reliable. In other embodiments, the limiting portion 15 can also be riveted, clamped, and magnetically connected to the columnar portion 14.

[0043] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
