[0032] An automotive wire harness durability test tooling according to the present disclosure, as shown in Figure 1As shown, the wire harness 101 includes a first end, a second end, and a wire harness 101 body located between the first end and the second end. The durability test tooling is used to test the movement durability performance of the wire harness 101 body. It is characterized by including,

[0033] An operating table 102;

[0034] A fixed-end component, arranged on the operating table 102, the fixed-end component having at least one first fixing member 103, and the first fixing member 103 being used to fix the first end;

[0035] A driving component, arranged on the operating table 102, the driving component having at least one second fixing member 104, the second fixing member 104 being used to fix the second end, and the driving component driving the second end to reciprocate along a predetermined trajectory so as to generate relative movement between the first end and the second end, thereby keeping the wire harness 101 body in a moving state during the test time.

[0036] By driving the second end of the wire harness 101 through the driving component to reciprocate relative to the first end according to a predetermined trajectory, it is possible to simulate the movement trajectory of the wire harness 101 multiple times in a short time to perform a durability test on the wire harness 101.

[0037] The automotive wire harness durability test tooling of the present disclosure has the advantages that by connecting the first end to the first fixing member 103 and the second end to the second fixing member 104, the wire harness 101 can be assembled to the test tooling through simple steps, and the durability tests of multiple wire harnesses 101 can be completed at one time, shortening the test cycle and having strong practicability.

[0038] According to an embodiment of an automotive wire harness durability test tooling of the present disclosure, the driving component further includes a bracket 105 arranged on the operating table 102, a driving device arranged on the bracket 105, and the second fixing member 104 is arranged at the output end of the driving device.

[0039] By arranging the bracket 105, a movement space can be formed between the output end of the driving device and the operating table 102. The second end is connected by the second fixing member 104 at the output end of the driving device, so that the second end of the wire harness 101 is driven by the driving device to reciprocate relative to the first end, so that the wire harness 101 body is in a moving state.

[0040] Specifically, the driving device includes a first driving mechanism 106 and a second driving mechanism 107;

[0041] The first driving mechanism 106 includes a first slide electric cylinder installed on the bracket 105, and the first slide electric cylinder has a first slide 108;

[0042] The second driving mechanism 107 includes a second slide electric cylinder connecting the first slide 108. The second slide electric cylinder has a second slide 109, and the second slide 109 is connected to the second fixing member 104.

[0043] By providing the first driving mechanism 106 and the second driving mechanism 107, the movement trajectory of the second end of the wire harness 101 relative to the first end can be made arc-shaped, better simulating the movement state of the wire harness 101 in actual applications.

[0044] More specifically, the movement trajectory of the first slide 108 is perpendicular to the movement trajectory of the second slide 109.

[0045] More specifically, the second slide 109 and the second fixing member 104 are connected by a transition member 110. One end of the transition member 110 is connected to the second slide 109 via an adapter member, and the second fixing member 104 is provided at the other end.

[0046] In specific implementation, the transition member 110 can be an L-shaped member. One end of the L-shaped member is connected to the second slide 109 via an adapter member, and the second fixing member 104 is provided at the other end of the L-shaped member. By changing the direction through the L-shaped member, it is convenient to connect the second end of the wire harness 101 to the second fixing member 104, avoiding interference between the second end, the second fixing member 104, and the bracket 105 during their installation.

[0047] More specifically, as Figure 3 shown, the adapter member includes a first convex portion 112 and a first concave portion 111. The first convex portion 112 is disposed within the first concave portion 111. One of the first convex portion 112 and the first concave portion 111 is provided on the second slide 109, and the other of the two is provided on the transition member 110.

[0049] More specifically, the driving device further includes a connecting member, and the first driving mechanism 106 is connected to the second driving mechanism 107 via the connecting member.

[0050] By providing the connecting member, the installation space between the first driving mechanism 106 and the second driving mechanism 107 can be increased, facilitating the assembly of the automotive wire harness durability test tooling and reducing the assembly difficulty.

[0051] More specifically, the connecting member includes a first connecting plate 113 and a second connecting plate 114. The first connecting plate 113 is perpendicularly connected to the second connecting plate 114. The first connecting plate 113 is connected to the first sliding table 108, and the second connecting plate 114 is connected to the second sliding table electric cylinder.

[0052] The first connecting plate 113 is connected to the first sliding table 108, and the connecting member can reciprocate within the movement track of the first sliding table 108 following the first sliding table 108; the second connecting plate 114 is connected to the second sliding table electric cylinder, and the movement track of the second sliding table 109 extends along the length direction of the second connecting plate 114. Thus, the movement track of the second sliding table 109 can be perpendicular to the movement track of the first sliding table 108, realizing the multi-angle movement of the main line of the wire harness 101.

The connecting structure includes a second convex portion 115 and a second concave portion 116. The second convex portion 115 is arranged within the second concave portion 116. One of the second convex portion 115 and the second concave portion 116 is arranged on the first sliding table 108, and the other is arranged on the first connecting plate 113.

[0054] By setting the connecting structure as the mutually cooperating second convex portion 115 and second concave portion 116, the first sliding table 108 can be installed on the first connecting plate 113 without damaging the first sliding table electric cylinder.

[0055] During specific implementation, at least one parallel sliding rail 119 is arranged on at least one side of the two sides of the bracket 105 located on both sides of the first driving device. A corresponding number of parallel sliding tables 120 are arranged on the first connecting plate 113. By slidably arranging the parallel sliding tables 120 on the corresponding parallel sliding rails 119, the second convex portion 115 is arranged in the second concave portion 116 to complete the connection between the first connecting plate 113 and the first sliding table 108 of the first sliding table electric cylinder; here, the parallel sliding rail 119 is parallel to the movement track of the first sliding table 108 along the sliding track of the parallel sliding table 120.

[0056] A drag chain 121 is further arranged on the bracket 105. The drag chain 121 is used to prevent the cables connecting the second sliding table electric cylinder, so as to protect the cables during the reciprocating movement of the second driving device following the first sliding table 108 of the first driving device and extend the service life of the cables connecting the second driving device.

[0057] In specific implementation, parallel slide rails 119 are arranged on at least one side of the two sides of the second driving device on the second connecting plate 114, corresponding numbers of parallel slide blocks 120 are arranged on the transition member 110, and by slidably arranging the parallel slide blocks 120 on the corresponding parallel slide rails 119, the first convex portion 112 is arranged in the first concave portion 111 to complete the connection between the transition member 110 and the second slide block of the second slide block electric cylinder; the parallel slide rails 119 here are parallel to the movement track of the second slide block 109 along the sliding track of the parallel slide blocks 120.

[0058] By arranging the mutually cooperating parallel slide rails 119 and parallel slide blocks 120, the force borne by the first slide block 108 when the first slide block 108 installs the connecting member and the force borne by the second slide block 109 when the second slide block 109 installs the connecting member can be reduced, and the service life of the first slide block electric cylinder and the second slide block electric cylinder can be prolonged.

[0059] According to an embodiment of an automotive wire harness durability test tooling of the present disclosure, the first fixing member 103 includes a fixing member 117 and a connecting member 118.
