Description

Technical Field

[0001] The invention relates to the technical field of automobile wiring harness installation, and in particular to a wiring harness fixing structure and a use method thereof. Background Art

[0002] As people love smart cars, more and more people choose smarter cars. The increase in the functions of smart cars has led to the widespread application of electronic control technology, more and more electrical components, and more and more wiring harnesses. The wiring harness layout has become a very important link and the key to whether the car can run stably. The layout of the automotive wiring harness not only needs to be reasonably designed according to the electrical principles, but the overall layout must also fully consider various relevant conditions. The layout of the wiring harness should consider the weight of the wiring harness, the convenience of the fixing method and the fixing position. The layout of the wiring harness fixing points is a key factor to ensure the safe and reliable operation of the wiring harness. Set up sufficient and reasonable fixing points to fix the wiring harness to avoid the wiring harness from sagging and shifting.

[0003] At present, there are more and more automotive wiring harnesses, and multi-line routing is inevitable. A reasonable multi-line fixing card structure is particularly important. It must be fixed firmly and small in size to avoid the wiring harness from moving around and getting tangled with each other and save layout space. The original multi-line wiring harness routing is that multiple wiring harnesses are routed side by side and fixed according to their respective fixing points, such as Figure 7 As shown, the harness ① is supported on the instrument cross beam and fixed at two fixing points, harness fixing point ① and harness fixing point ② in the figure. The harness ② is supported on the instrument cross beam and fixed at two fixing points, harness fixing point ① and harness fixing point ② in the figure. Figure 7 The two fixed points of the middle harness fixing point ③ and harness fixing point ④ are fixed. In this path, two harnesses are routed in parallel to realize the harness connection function. This harness fixing method requires a large space and cannot be arranged in a small space or the harnesses interfere with each other. The second is to use a multi-line card to fix the harness. Figure 8 As shown, the wiring harness ① and the wiring harness ② are supported on the instrument cross beam and pass through Figure 8 The Zhongduo wire card fixes the wire harness ① and the wire harness ② together to realize the wire harness connection function. This wire harness fixing method can prevent the wire harness from swinging too much, causing the two wire harnesses to interfere with each other or with surrounding parts. However, there are differences in the fixing position of this wire harness card, the wire harness direction assembly error is large, and the wire harness is in poor condition after assembly.

DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] Example 1

[0036] In a typical embodiment of the present invention, a wiring harness fixing structure is provided, such as Figure 1-Figure 6The figure includes a wiring harness base 1, a first wiring harness groove 2 and a second wiring harness groove 3; the first wiring harness groove 1 and the second wiring harness groove 2 are both detachably mounted on the wiring harness base 1 through a clamping structure 4, and are fixed in cooperation with a locking structure 5; a first wiring harness accommodating space 21 is arranged on the first wiring harness groove 1, and a second wiring harness accommodating space 31 is arranged on the second wiring harness groove 3; the wiring harness base 1 is also provided with two mounting holes 11, and the two mounting holes 11 are cooperated with a wiring harness fixing card 12 to fix the third wiring harness 9; a limiting structure 6 is arranged at the bottom of the wiring harness base 1, and the wiring harness base 1 is mounted on the vehicle body sheet metal 10 through the limiting structure 6.

[0037] In this embodiment, the wiring harness base 1 is detachably connected to the first wiring harness groove 2 and the second wiring harness groove 3. At the same time, the first wiring harness 7 and the second wiring harness 8 are respectively fixed by the first wiring harness groove 2 and the second wiring harness groove 3. Two mounting holes are also provided on the wiring harness base 1, and the third wiring harness 9 is fixed by a wiring harness fixing card, so that the directions of three wiring harnesses can be fixed at the same time by one wiring harness fixing structure, avoiding the risk of the wiring harnesses moving randomly on this path and getting entangled with each other.

[0038] like Figure 3-Figure 5 As shown, the clamping structure 4 includes a slide rail 41 arranged on the upper surface of the wiring harness base 1 and a slide groove 42 arranged at the bottom of the wiring harness groove. The wiring harness groove is installed on the wiring harness base 1 through the cooperation of the slide rail 41 and the slide groove 42. Further, two slide rails 41 are provided, and the two slide rails are arranged in parallel, respectively used to install the first wiring harness groove 2 and the second wiring harness groove 3, so that the first wiring harness 7, the second wiring harness 8 and the third wiring harness 9 are installed on the same plane. By fixing the three wiring harnesses on the same plane, the space occupied by the fixed wiring harnesses can be minimized.

[0039] Furthermore, the slide rail 41 is H-shaped, and the slide groove 42 includes two L-shaped grooves with openings arranged opposite to each other and separated by a set distance. The L-shaped grooves are engaged with two sides of the H-shaped slide rail, and the cooperation between the slide rail 41 and the slide groove 42 enables rapid installation and disassembly between the wiring harness groove and the wiring harness base.

[0040] In order to fix the harness groove, a locking structure 5 is also provided, which includes a slot 51 provided on the side of the harness base 1 and a protrusion 52 provided at the bottom of the harness groove, and the protrusion 52 is engaged in the slot 51 to limit the harness groove. The slot 51 and the protrusion 52 both have a certain elasticity, which can ensure that when the slide rail 41 slides into the slide groove 42, the slot 51 and the protrusion 52 are deformed to a certain extent and can be reset when the protrusion 52 is placed in the slot 51; the contact surface between the slot 51 and the protrusion 52 during the sliding process is an inclined surface, which facilitates the protrusion 52 to slide into the slot 51.

[0043] Furthermore, the lower part of the limiting protrusion 62 is an inclined surface 621, and the upper part is provided with a step surface 622. The inclined surface 621 serves as a guide for the limiting column 61 to be inserted into the mounting hole on the vehicle body sheet metal.

[0044] In this embodiment, two limit cards 63 are provided, which are respectively located on both sides of the limit column 61. After the wiring harness base 1 is installed on the body sheet metal 10, the free end of the limit card 63 abuts against the surface of the body sheet metal 10. That is, after the limit column 61 is inserted into the mounting hole on the body sheet metal 10, the body sheet metal is just located at the step surface 622 on the limit protrusion 62, and the body sheet metal 10 is pressed by the limit card 63 to prevent the wiring harness base 1 from moving, thereby improving the stability of the wiring harness fixation.

[0045] The wire harness fixing structure provided by the present invention has a wire harness base fixed on the body sheet metal by a limiting structure, a first wire harness and a second wire harness are fixed by a first wire harness slot and a second wire harness slot installed on the wire harness base, the wire harness slot can be disassembled and assembled separately on the wire harness base, and the third wire harness is constrained by a wire harness fixing card cooperating with two mounting holes on the wire harness base. This wire harness fixing structure can fix and keep the wire harness path smooth and non-interfering, and reduces the layout space and assembly error.
