[0040] Due to the special usage requirements of in-vehicle optical cables, strict requirements are imposed on their bending and torsion performance. Currently, there is no dedicated test device for the bending and torsion of in-vehicle optical cables in the market. Ordinary test devices are relatively large and cannot meet the requirements in terms of torsion length and bending radius. Moreover, bending and torsion require separate testing with two devices, which reduces the testing efficiency.
[0041] The present utility model proposes an in-vehicle optical cable testing device 100 to solve the above problems.
[0042] Please refer to Figures 1 to 2 , in an embodiment of the present utility model, the torsion performance test and bending performance test of the in-vehicle optical cable are concentrated on one test device. During actual use, it is possible to complete the separate tests of bending and torsion, as well as the combined performance test of bending and torsion on one test device. Specifically, in this embodiment, the bending test structure 3 and the torsion test structure are installed on the same base 1. Among them, the bending test structure 3 is provided with a curved receiving groove 32. When testing the bending performance of the in-vehicle cable, the in-vehicle cable can be limited and fixed in the receiving groove 32 along the bending shape of the receiving groove 32. When conducting the separate bending performance test, a corresponding test device can be connected to the end of the in-vehicle optical cable to detect the difference in the performance parameters of the in-vehicle optical cable before and after bending. When conducting the torsion performance test, the main body of the part of the in-vehicle optical cable to be tested is fixed between two clamps 4 arranged opposite to each other in the first direction. At least one of the two clamps 4 is a rotatably installed clamp structure, which can rotate around the axis in the first direction. Thus, after the in-vehicle optical cable is fixed on the two clamps 4, the rotating clamp in the clamps 4 can drive a part of the fixed in-vehicle optical cable to reciprocally twist around its axis, thereby detecting the torsion performance of the in-vehicle optical cable. It can be imagined that both of the two clamps 4 can be set as the rotating clamps. When set as two rotating clamps, the two rotating clamps can intermittently perform reciprocating torsion. Similarly, during the torsion test, a corresponding test device can be connected to both ends of the in-vehicle optical cable to obtain the relevant data parameters of the in-vehicle optical cable before and after the torsion test. Moreover, after the bending test structure 3 and the torsion test structure are both arranged on the base 1, the in-vehicle optical cable can be simultaneously fixed in the two clamps 4 and the receiving groove 32, and then through the above operations, the combined test of the bending performance and torsion performance of the in-vehicle optical cable can be simultaneously carried out, which can make the entire test process more convenient and is conducive to improving the test efficiency of the bending test and torsion test performance of the in-vehicle optical cable.
[0043] When testing the torsion of the in-vehicle optical cable, in many cases, it is necessary to test in-vehicle optical cables of different lengths according to the specific experimental requirements. In this embodiment, to solve the above problems and improve the applicability of the entire device, one of the clamps 4 is set as a linear movable clamp, such asFigure 3 and Figure 4 As shown, the linear movable fixture has a moving stroke in the first direction. During specific use, the actual position of the linear movable fixture in the first direction can be adjusted according to actual test requirements to adjust the length of the in-vehicle optical cable between the two fixtures 4, so that various different test requirements can be completed by one test device.
[0044] In this embodiment, in order to meet different requirements for torsional performance testing, targeted designs are made for the specific functional effects of the two fixtures 4. Specifically, one of the fixtures 4 is set as a rotating fixture, which can rotate around the axis formed in the first direction to provide the torsional effect required during the torsional performance test. The other fixture 4 is set as a linear movable fixture, which has a moving effect in the first direction and can adjust the horizontal relative distance from the rotating fixture, so as to adjust the torsional test length of the corresponding in-vehicle optical cable according to the specific test requirements of the in-vehicle optical cable.
[0045] Specifically, as Figure 2 , Figure 3 and Figure 4 As shown, the reason why the linear movable fixture can move in the first direction is that a guiding motion structure is further provided on the base 1. Among them, the guiding slide 2 in the guiding motion structure is arranged in the first direction, the slider 21 is slidably installed on the guiding slide 2, and the linear movable fixture is installed on the upper end surface of the slider 21. During actual operation, by adjusting the position of the slider 21 on the guiding slide 2, the horizontal distance between the linear movable fixture and the rotating fixture can be correspondingly adjusted. At the same time, due to the certain frictional force between the slider 21 and the guiding slide 2, the relative position stability between the two fixtures 4 can be ensured during the torsional performance test. And it can be imagined that the guiding motion structure in this embodiment can be replaced by various linear adjustment structures, such as cylinder assemblies and linear motors, etc., all of which can achieve the distance adjustment effect between the two fixtures 4 and can be set according to actual situations.
[0046] Under certain test requirements, it is necessary to suspend a load at one end of the in-vehicle optical cable to provide mechanical tension and continue the torsional performance test under the current mechanical tension condition. To solve the above problems, a corresponding suspension structure 8 is provided in this embodiment for guiding and suspending the load. Specifically, as Figure 2As shown, the mounting bracket 81 in the suspension structure 8 is arranged on the side of the linear movable fixture away from the rotary fixture. During use, one end of the vehicle-mounted cable is passed through the linear movable fixture for fixation. Then, after winding a certain number of turns in the guiding groove 821 of the guiding wheel 82 at its end, according to actual requirements, a load with a certain weight is suspended at the tail of the vehicle-mounted optical cable. The tail position of the vehicle-mounted optical cable provides a certain load tension, and drives the guiding wheel 82 to rotate, so that when the vehicle-mounted optical cable is subjected to a torsion test, there is a certain tension along its line, thus meeting the current performance test requirements. And the height of the highest point of the guiding wheel 82 is at the same vertical height as the central axis of the linear movable fixture. With such a setting, it can be ensured that when the vehicle-mounted cable is subjected to a torsion test, it can maintain a straight state as much as possible. Combined with the guiding of the guiding wheel 82, the loss of force can be minimized, thereby ensuring the credibility of the test results.
[0047] During the test of the torsion test piece, it is necessary to drive the vehicle-mounted cable to reciprocally twist around its line direction. Therefore, in this embodiment, a corresponding driving structure is provided to drive the rotary fixture to rotate through the driving structure, so as to complete the torsion test operation. Specifically, when the driving structure works, the driving motor 5 drives the driving gear 52 on its output shaft 51 to rotate. During the rotation of the driving gear 52, the driven gear 53 engaged with it drives the rotary fixture to reciprocally rotate, so as to perform a torsion test on the vehicle-mounted cable between the rotary fixture and the linear movable fixture. It can be imagined that in addition to the motor-gear structure disclosed above, the driving structure can also be set as a motor-belt assembly, or a cylinder-link assembly, etc., and can be selectively used according to actual situations.
[0048] In order to ensure the safety during the torsion performance test, usually the corresponding transmission structure is designed in a concealed manner. In this embodiment, as Figure 1 shown, a safety cover 6 is provided on the driving gear 52, the driven gear 53 and the rotary fixture for isolation.
[0049] As described in the above embodiment, during the actual test, it is necessary to adjust the horizontal distance between the linear movable fixture and the rotary fixture through the slider 21 and the guiding slide 2. In order to further ensure that when adjusting the distance, the horizontal distance between the linear movable fixture and the rotary fixture can be observed more intuitively, on the base 1 there is Figure 1The scale 7 shown. It should be noted that the scale 7 is arranged along the first direction, one end of it is flush with the corresponding end of the rotating fixture to the linear movable fixture, and the end of the linear movable fixture opposite to the rotating fixture is flush with the slider 21. With such a setting, the horizontal distance between the linear movable fixture and the rotating fixture can be intuitively obtained through the scale corresponding to the end of the slider 21 on the scale line.
[0050] When the vehicle-mounted optical cable is fixed by the fixture 4, as Figure 2 and Figure 4 shown, the vehicle-mounted optical cable is threaded through the clamping space 421 formed by a plurality of clamping heads 42. Rotating the adjustment knob 43 drives the plurality of clamping heads 42 to move in the first direction within the support base. When the front-end inclined surfaces of the plurality of clamping heads 42 are in contact with the inclined inner wall at the end of the clamping seat 41, it will drive the plurality of clamping heads 42 to contract simultaneously in their radial directions, thereby clamping and fixing the vehicle-mounted optical cable located in the clamping space 421. When releasing, driving the plurality of clamping heads 42 to move in the reverse direction through the adjustment knob 43 can achieve the release of the vehicle-mounted optical cable. It can be imagined that the fixture 4 can also be set as a three-jaw chuck or an electric drive structure, which can be selectively used according to the actual situation.
[0051] As Figure 2 shown, in the bending test structure 3, it includes a test plate body 31 detachably installed on the upper end surface of the base 1. The test plate body 31 is arranged on the base 1. The test plate body 31 includes a first plate portion 311 and two second plate portions 312. The two second plate portions 312 are arranged at two adjacent ends of the first plate portion 311 in the horizontal direction. The bending portion 321 in the accommodation groove 32 is arranged on the first plate portion 311. The two ends of the bending portion 321 are respectively provided with two linear portions 322, and the two linear portions 322 are respectively arranged on the two second plate portions 312. When testing the vehicle-mounted optical cable, the vehicle-mounted optical cable to be tested can be correspondingly installed in the accommodation groove 32. At the same time, in order to verify the different effects of bending with multiple different radii on the vehicle-mounted optical cable, the bending portion 321 in the accommodation groove 32 is set as a plurality of bending portions 321 with different radii. Specifically, when using, the vehicle-mounted optical cable can be fixed in the accommodation groove 32 with the corresponding radius according to the actual test requirements.
[0052] In addition, it can be conceived that when performing a torsion test on the in-vehicle optical cable in this solution, the driving motor 5 needs to be driven and controlled. In this solution, a corresponding control device is provided. During actual use, the working time of the driving motor 5, the torsion angle of the output shaft 51 of the driving motor 5, and the reciprocating rotation speed of the motor can be set through the control device. Alternatively, the overall adjustment structure formed between the slider 21 and the guide slide 2 can be set as an electric drive structure, etc. The relevant electric drive structure can be set with unified parameters through the control device, so as to achieve semi-automatic continuous testing, thereby increasing the convenience and stability during the testing process.
[0053] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
