Description

Technical Field

[0001] The present application relates to the technical field of automobile wiring harnesses, and in particular to an automobile wiring harness. Background Art

[0002] Automotive wiring harnesses are composed of wires, connectors, wiring harness wrappings, wiring harness fixings (snaps, rubber parts, wiring harness brackets, etc.) and wiring harness accessories. Among them, the types of wiring harness wrappings mainly include corrugated tubes, PVC tape, cloth-based tape, velvet tape, sponge tape and aluminum foil tape.

[0003] The existing wiring harnesses are not put together after they are assembled, which causes the branches of multiple wiring harnesses to easily become entangled due to shaking during transportation. When they are removed later, a lot of manpower is required to sort out the entangled wires, which is time-consuming and labor-intensive.

[0004] Therefore it is necessary to provide a kind of automobile wiring harness to solve the above problems.

[0005] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Utility Model Content

[0007] The technical solution adopted by the present application to solve its technical problem is: an automobile wiring harness, comprising a protective tube and a gathering component slidably sleeved on the outside of the protective tube; the gathering component comprises two mounting heads and an elastic rope; the elastic rope is located between the two mounting heads, and a plurality of elastic ropes are provided, and the plurality of elastic ropes are circumferentially arranged with the protective tube as the center, and the elastic ropes are axially parallel to the protective tube; a plurality of branch 1s are provided on the side of the protective tube, and a branch 2 is provided at one end of the protective tube; one of the mounting heads is slidably arranged on the protective tube, and the other is provided with a plurality of branch 1s. The mounting head is slidingly arranged in parallel with the axial direction, and the mounting head is clearance-matched with the protective tube and branch 2, and the multiple branch 1s are located between the two mounting heads; thus, before packing, the multiple branch 1s are placed between the elastic ropes, the mounting head at the protective tube is fixed, and the mounting head at branch 2 is rotated to twist the elastic rope into a spiral; the elastic rope gathers the branch 1 close to the protective tube, thereby realizing the gathering of the automobile wiring harness, reducing the scattered parts of branch 1 and branch 2, and indirectly reducing the probability of entanglement with other wiring harness branches during subsequent transportation.

[0008] Furthermore, the mounting head includes a circular ring seat, blades, a turntable, and a frame; the inner diameter of the circular ring seat is larger than the diameter of the protective tube, and a placement groove is provided on one side of the circular ring seat; the frame is fixedly installed in the placement groove, the turntable is rotatably arranged in the placement groove, and is located on the side of the frame away from the circular ring seat, and a rotation damping is arranged between the turntable and the inner wall of the placement groove; there are multiple blades, and the multiple blades are slidingly arranged between the turntable and the frame, and are centrally symmetrically distributed, the turntable is used to control the synchronous movement of multiple blades, and the frame is used to limit the movement trajectory of multiple blades; thus, the turntable is rotated, and the turntable drives the blades to move, and since the frame limits the blades, the multiple blades open and close; and then the fixing of the mounting head is achieved by synchronously retracting and clamping the protective tube or branch 2 by multiple blades.

[0009] Furthermore, a plurality of limit grooves are radially provided on the end face of the frame, and the plurality of limit grooves are evenly distributed circumferentially, and the limit grooves are oblique grooves; the blades correspond one to one with the limit grooves, and a limit key is provided on the side of the blade close to the frame, and the limit key and the corresponding limit groove are slidably matched; thus, the frame controls the movement direction of the blades through the limit grooves, so that the plurality of blades can realize opening and closing actions when moving synchronously.

[0011] Furthermore, a support arm is movably provided on the side of the annular seat away from the frame, and the support arms are provided in plurality, and the plurality of support arms are arranged circumferentially, with one end of the support arm located outside the annular seat; the support arm is located outside the annular seat and is fixedly connected to the elastic rope on the side close to branch two; thereby, the movable support arm can control the diameter of the circle formed by the plurality of support arms, thereby changing the diameter of the spiral shape of the elastic rope; this facilitates the later tightening of the internal branch one and the protective tube.

[0012] Furthermore, the end of the support arm away from the elastic rope is connected to the circular ring seat through a rotating shaft, and a rotation damper is provided on the rotating shaft; thus, after the elastic rope is spirally driven to wrap the protective tube, the support arm is rotated, so that the diameter formed by the multiple support arms is shortened, thereby achieving the shortening of the spiral diameter of the elastic rope, thereby achieving a tight wrapping state between the elastic ropes.

[0013] Furthermore, an arc-shaped groove is provided on the side of the annular seat away from the frame, and the direction of the arc-shaped groove is distributed along the radial direction of the annular seat; the arc-shaped groove corresponds to the support arm one by one; a sliding part is provided at the end of the support arm away from the elastic rope, and the sliding part is connected to the corresponding arc-shaped groove through sliding cooperation, and a sliding damping is provided between the sliding part and the corresponding arc-shaped groove; thus, the elastic rope is spirally driven to drive the branch to wrap around the protective tube, and the support arm is controlled to slide inward, so that the part of the support arm outside the annular seat is shortened, thereby achieving the shortening of the spiral diameter of the elastic rope, thereby achieving a tight wrapping state between the elastic ropes.

[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0027] like Figure 1 As shown, the present application provides an automotive wiring harness, comprising a protective tube 1 and a gathering component that is slidably sleeved on the outside of the protective tube 1; the gathering component comprises two mounting heads 21 and an elastic cord 22; the elastic cord 22 is located between the two mounting heads 21, and a plurality of elastic cords 22 are provided, and the plurality of elastic cords 22 are circumferentially arranged with the protective tube 1 as the center, and the elastic cords 22 are axially parallel to the protective tube 1; a plurality of branch lines 12 are provided on the side of the protective tube 1, and a branch line 2 13 is provided at one end of the protective tube 1; one of the mounting heads 21 is slidably arranged on the protective tube 1, and the other mounting head 21 is slidably arranged in the axial direction. On the other hand, the mounting head 21 is clearance-fitted with the protective tube 1 and the branch 2 13, and the plurality of branches 12 are located between the two mounting heads 21; thus, before packing, the plurality of branches 12 are placed between the elastic ropes 22, the mounting head 21 at the protective tube 1 is fixed, the mounting head 21 at the branch 2 13 is rotated, and the elastic rope 22 is twisted into a spiral; the elastic rope 22 gathers the branch 12 close to the protective tube 1, thereby realizing the gathering of the automotive wiring harness, reducing the scattered parts of the branch 12 and the branch 2 13, and indirectly reducing the probability of entanglement with other wiring harness branches during subsequent transportation.

[0028] Reference Figure 2-Figure 4The mounting head 21 includes a circular ring seat 221, blades 213, a turntable 214, and a frame 215; the inner diameter of the circular ring seat 221 is larger than the diameter of the protective tube 1, and a placement groove is opened on one side of the circular ring seat 221; the frame 215 is fixedly installed in the placement groove, and the turntable 214 is rotatably set in the placement groove and is located on the side of the frame 215 away from the circular ring seat 221; a plurality of blades 213 are provided, and the plurality of blades 213 are slidably set between the turntable 214 and the frame 215, and are centrally symmetrically distributed, the turntable 214 is used to control the synchronous movement of the plurality of blades 213, and the frame 215 is used to limit the movement trajectory of the plurality of blades 213; thus, the turntable 214 is rotated, and the turntable 214 drives the blades 213 to move. Since the frame 215 limits the blades 213, the plurality of blades 213 open and close; and then the fixing of the mounting head 21 is achieved by synchronously retracting and clamping the protective tube 1 or branch 2 13.

[0029] The end surface of the frame 215 is radially provided with a plurality of limiting grooves 2151, which are evenly distributed circumferentially and are oblique grooves. The blades 213 correspond one to one with the limiting grooves 2151. A limiting key 2131 is provided on the side of the blade 213 close to the frame 215. The limiting key 2131 and the corresponding limiting groove 2151 are in sliding engagement. The limiting groove 2151 controls the movement direction of the blade 213.

[0030] A groove ring 2141 is provided on the side of the turntable 214 close to the blade 213, and the groove ring 2141 is a polygonal groove; a cam pair 2142 is provided on the side of the blade 213 away from the frame 215, and the cam pair 2142 is slidably set in the groove ring 2141. The number of sides of the polygonal groove corresponds one to one with the number of cam pairs 2142; therefore, when the turntable 214 is driven, the turntable 214 causes the blade 213 to move through the cam pair 2142. Under the joint action of the frame 215 and the turntable 214, the blade 213 forms an opening and closing action, and this mechanism effectively saves space.

[0031] In addition, refer to Figure 1-Figure 3 A support arm 212 is movably provided on the side of the annular seat 221 away from the frame 215, and a plurality of support arms 212 are provided. The plurality of support arms 212 are arranged circumferentially, and one end of the support arm 212 is located outside the annular seat 221; the support arm 212 is located outside the annular seat 221 and is fixedly connected to the elastic rope 22 on the side close to the branch 2 13; thus, the movable support arm 212 can control the diameter of the circle formed by the plurality of support arms 212, thereby changing the spiral diameter of the elastic rope 22; this is convenient for tightening the internal branch 12 and the protective tube 1 in the later stage.

[0032] Example 1: The first connection method of the support arm 212 and the annular seat 221 is as follows:

[0033] Reference Figure 5The end of the support arm 212 away from the elastic rope 22 is connected to the ring seat 221 through a rotating shaft, and a rotation damper is provided on the rotating shaft; thus, the elastic rope 22 spirally drives the branch 12 to wrap the protective tube 1, and then rotates the support arm 212, so that the diameter formed by the multiple support arms 212 is shortened (such as Figure 5 The dotted line forms the part), thereby shortening the spiral diameter of the elastic cord 22, thereby achieving a tight wrapping state between the elastic cords 22.

[0034] Embodiment 2: A second connection method between the support arm 212 and the annular seat 221 is as follows:

[0035] An arcuate groove is provided on the side of the annular seat 221 away from the frame 215, and the direction of the arcuate groove is distributed along the radial direction of the annular seat 221; the arcuate groove corresponds one to one with the support arm 212; a sliding portion is provided at the end of the support arm 212 away from the elastic rope 22, and the sliding portion is connected to the corresponding arcuate groove through sliding cooperation, and a sliding damping is provided between the sliding portion and the corresponding arcuate groove; thus, after the elastic rope 22 drives the branch 12 to wrap around the protective tube 1 in a spiral shape, the support arm 212 is controlled to slide inward, so that the part of the support arm 212 outside the annular seat 221 is shortened, thereby achieving the shortening of the spiral diameter of the elastic rope 22, thereby achieving the tight wrapping state between the elastic ropes 22.

[0036] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
