[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 6 As shown, the utility model provides the following technical solutions: a detection device for detecting the performance of an automobile wiring harness, comprising a support member, on which two relatively movable fixing members 10 are arranged, and the fixing member 10 comprises a fixing frame 102, one side of the fixing frame 102 is recessed to form a limiting groove 101, a moving plate 107 is installed inside the limiting groove 101, and a telescopic part is installed on the fixing frame 102, the telescopic end of the telescopic part is connected to the moving plate 107, the moving plate 107 is driven to move relative to the limiting groove 101 by the telescopic part, and a fixed cavity that interferes with the automobile wiring harness is formed between the moving plate 107 and the limiting groove 101.

[0023] Through the above technical scheme, when personnel need to perform a tensile test on an automobile wiring harness, multiple automobile wiring harnesses that need to be tested are placed in the limiting groove 101 on the fixing frame 102. After the automobile wiring harness is placed, the telescopic part works, and then the telescopic part drives the movable plate 107 to move in the limiting groove 101 until the movable plate 107 and the limiting groove 101 are in contact with the wiring harness to be fixed. After one end of the wiring harness is fixed, the other end of all wiring harnesses that need to be tested is placed in the limiting groove 101 on another fixing frame 102. After the automobile wiring harness is placed, the telescopic part works, and then the telescopic part drives the movable plate 107 to move in the limiting groove 101 until the movable plate 107 and the limiting groove 101 are in contact with the wiring harness to be fixed. When the two ends of the automobile wiring harness that need to be tested are fixed, the two fixing frames 102 are moved relative to each other to perform a tensile test on the automobile wiring harness.

[0024] In addition, in the present invention, when the limiting groove 101 contacts the automobile wiring harness, in order to make the automobile wiring harness more stable, Figure 4-Figure 5 As shown, the inner wall of the limiting groove 101 facing the side of the automobile wiring harness is concave to form a plurality of grooves 106 .

[0025] In this embodiment, when the movable plate 107 and the limiting groove 101 contact the wiring harness, the groove 106 cooperates to make the fixing frame 102 more secure when contacting the automobile wiring harness.

[0026] Specifically, in one embodiment, regarding the telescopic portion:

[0027] like Figure 1-Figure 2 , Figure 5-Figure 6 As shown, the telescopic part includes an electric push rod 103, which is fixedly connected to the fixed frame 102, a top rod 104 is fixedly connected to the top of the movable plate 107, and a top plate 105 is connected between the telescopic end of the electric push rod 103 and the top of the push rod 104.

[0028] In this embodiment, a plurality of automobile wiring harnesses to be tested are placed in the limiting groove 101 on the fixing frame 102. After the automobile wiring harnesses are placed, the electric push rod 103 is operated, and then the electric push rod 103 drives the fixing frame 102 to move, and the fixing frame 102 drives the push rod 104 to move, and the push rod 104 drives the moving plate 107 to move, so that the moving plate 107 moves in the limiting groove 101 until the moving plate 107 and the limiting groove 101 contact the wiring harness to fix it. After one end of the wiring harness is fixed, the other end of all the wiring harnesses to be tested are placed. After the automobile wiring harness is placed in the limiting groove 101 on the other fixing frame 102, the electric push rod 103 works, and then the electric push rod 103 drives the fixing frame 102 to move, and the fixing frame 102 drives the push rod 104 to move, and the push rod 104 drives the moving plate 107 to move, so that the moving plate 107 moves in the limiting groove 101 until the moving plate 107 and the limiting groove 101 are in contact with the wiring harness to fix it. When it is necessary to test the two ends of the automobile wiring harness, the two fixing frames 102 are moved relative to each other to perform a tensile test on the automobile wiring harness.

[0029] In addition, in the present invention, how the two fixing frames 102 move relative to each other is as follows: Figure 1-Figure 4 As shown, the device also includes a base plate 4, the top of the base plate 4 is sunken along its length direction to form a guide groove 5, and two top frames 8 are symmetrically fixedly connected to the top of the base plate 4, the inside of the guide groove 5 is rotatably connected to a screw rod 6, a movable moving part 3 is sleeved between the two screw rods 6, one of the fixed frames 102 is rotatably connected to the moving part 3, and the other fixed frame 102 is fixedly connected between the two top frames 8, and a third motor 7 is fixedly connected to the base plate 4, and the output end of the third motor 7 is connected to the screw rod 6.

[0030] In the present embodiment, after the wiring harness to be tested is fixed between two fixed frames 102, the top frame 8 and the screw rod 6 are supported by the base plate 4, one of the fixed frames 102 is supported by the top frame 8, the moving part 3 is supported by the screw rod 6, and the other fixed frame 102 is supported by the moving part 3. The screw rod 6 is driven to rotate by the third motor 7, and the moving part 3 is moved along the length direction of the screw rod 6 through the cooperation of the guide groove 5. One of the fixed frames 102 is driven by the moving part 3 to move relative to the other fixed frame 102, thereby stretching the automobile wiring harness for testing.

[0031] Specifically, in one embodiment, regarding the above-mentioned moving part 3:

[0032] like Figure 1-Figure 4 , Figure 5-Figure 6 As shown, the moving member 3 includes a mounting frame 32, wherein a fixing frame 102 is rotatably connected to the mounting frame 32, and a moving seat 31 is fixedly connected to the bottom of the mounting frame 32, and the moving seat 31 is sleeved on the screw rod 6;

[0033] The mounting frame 32 is fixedly connected with a second motor 33 , and an output end of the second motor 33 is connected to the fixing frame 102 .

[0034] In this embodiment, when the automobile wiring harness is long, the fixing frame 102 is supported by the mounting frame 32, and the second motor 33 is operated to drive the fixing frame 102 to rotate relative to the mounting frame 32, so that the fixing frame 102 and the movable plate 107 are wound around the automobile wiring harness, and then the automobile wiring harness is stretched for a tensile test.

[0035] After the car wiring harness is tested, in order to quickly remove the tested car wiring harness, such as Figure 1-Figure 4 As shown, a bottom plate 1 is arranged below the substrate 4, and two support frames 2 are symmetrically fixedly connected to the top of the bottom plate 1. The substrate 4 is rotatably connected between the two support frames 2, and a first motor 9 is fixedly connected to one of the support frames 2, and the output end of the first motor 9 is connected to the substrate 4.

[0036] In this embodiment, the second motor 33 works to drive the fixed frame 102 to rotate relative to the mounting frame 32, so that the fixed frame 102 and the movable plate 107 unwind the automobile wiring harness, and the support frame 2 is supported by the bottom plate 1, and the substrate 4 is supported by the support frame 2. When the automobile wiring harness test is completed, the first motor 9 on the support frame 2 works to drive the substrate 4 to rotate relative to the support frame 2, so that the tested automobile wiring harness on the substrate 4 falls off, thereby completing the test of the automobile wiring harness.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
