[0018] like Figures 1-3As shown, this embodiment provides a car charging cable testing device, including: a support frame 1, a testing frame 2 mounted on the support frame 1, four adjusting wheels at the bottom of the support frame 1, one end of the testing frame 2 being rotatably connected to the support frame 1, and the other end of the testing frame 2 being a guide end 3. The guide end 3 is connected to the upright 4 on the support frame 1 via a height adjusting seat 5. The height adjusting seat 5 includes a first slider 51 and a first knob 52. The first slider 51 is slidably limited on the first guide rail 10 of the testing frame 2. The first slider 51 is slidably limited in the first longitudinally opened first strip hole 41 on the upright 4 via the first knob 52. The first knob 52 includes a grip and a body. The body passes through the first strip hole 41 and is threadedly connected to the first slider 51. When the first knob 52 is tightened, the testing frame 2 is fixed on the upright 4. When it is loosened, the body can move in the first strip hole 41 to adjust the tilt angle of the testing frame 2 on the support frame 1, thereby adjusting the height of the testing frame 2. In this embodiment, the length of the test frame 2 is greater than the distance from the pivot point of the test frame 2 on the support frame 1 to the upright 4.

[0019] like Figures 3-4 As shown, the guide end 3 is provided with a lead wire assembly 6, which includes a roller 7 rotatably connected to the guide end 3 (i.e., the roller 7 is rotatably connected to the guide end 3 via a rotating shaft). The roller 7 is provided with a cable guide groove 71, which is used for guiding and supporting the cable. The lead wire assembly 6 also includes a spacing adjustment assembly 11 mounted on the test frame 2. The spacing adjustment assembly 11 is provided with vertically arranged rollers 12 spaced apart, with a guide gap 121 reserved between the spaced rollers 12. The guide gap 121 corresponds to the cable guide groove 71. The spacing adjustment assembly 11 includes a set of Support rods 13 are spaced apart on the test frame 2. The support rods 13 are connected to the second slot 151 at one end of the limiting plate 15 via a second knob 14. The second knob 14 includes a handle and a body. The body and the support rods 13 are threaded together. When the second knob 14 is tightened, the body does not move in the second slot 151. When the second knob 14 is loosened, the body can move in the second slot 151. The roller 12 is installed at the other end of the limiting plate 15. By adjusting the guide gap 121 of the roller 12, the control position of the roller 12 on the cable is adjusted.

[0020] like Figure 9As shown, a mounting base 8 that can move relative to the lead wire assembly 6 is slidably disposed on the test frame 2. A clamp 9 for holding the charging head is installed on the mounting base 8. A second guide rail 161 is provided on the test frame 2. The mounting base 8 includes a second slider 162 that is slidably disposed on the second guide rail 161. A mounting groove 17 is provided on the second slider 162. The clamp 9 includes a pair of clamping flaps 91 that can open and close relative to each other. The pair of clamping flaps 91 are respectively screwed onto the side wall of the mounting groove 17 by a third knob 18. The third knob 18 is threadedly connected to the clamping flaps 91. When the third knob 18 is tightened, the clamping flaps 91 clamp the charging head. Each clamping flap 91 is provided with a guide post that is slidably connected to the side wall of the mounting groove 17. By adjusting the clamping flaps 91, clamps of different sizes can be used to hold the charging head, so as to meet the testing requirements of the test device for different types of charging cables.

[0021] The test frame 2 is rotatably connected to the support frame 1 at one end, and the guide end 3 is slidably connected to the support frame 1 through a height adjustment seat 5, which serves to adjust the height. When facing charging piles of different heights, the height of the test frame 2 can be adjusted by the height adjustment seat 5. The lead wire assembly 6 and rollers 7 are set to support and limit the cable, so as to avoid the cable position being uncontrollable and affecting the test results. The clamp 9 is used to fix the clamps of different product types.

[0022] In one embodiment of this utility model, the mounting base 8 is driven onto the test frame 2 by a moving drive unit 19. The moving drive unit 19 includes a motor 20 mounted on the test frame 2. The output shaft of the motor 20 is driven by a reducer and a drive wheel 211. The drive wheel 211 is driven by a synchronous belt 212 and a driven wheel 213 mounted on the test frame 2. The mounting base 8 is fixedly connected to the synchronous belt 212, which ensures uniform speed during stretching and retraction, as well as stability in repeatability testing. See details below. Figures 5-7 .

[0023] Working principle: When testing a car charging station, the height of the test frame 2 is adjusted according to the height of the charging station using the height adjustment seat 5. The operator adjusts the height by moving the first knob 52 along the first slot 41. When the first slider 51 moves upward along the first slot 41, it slides upward along the first guide rail 10, raising the test frame 2; when the first slider 51 moves downward along the first slot 41, it slides downward along the first guide rail 10, lowering the test frame 2. After successful adjustment, before fixing the test device to the car charging station using the adjusting wheels, to clamp and fix the charging head onto the clamp 9, the operator first separates the two clamping segments 91, places the charging head between the two segments 91, and then rotates the third knobs 18 on both sides. 1. Move the rollers towards each other until they clamp the charging head and stop rotating. Then, place the cable on the roller 7 and in the cable guide groove 71. The cable is in the guide gap 121 between the rollers 12. The operator adjusts the rollers 12 with the gap adjustment component 11 until they are close to the cable. The operator turns the second knob 14 to bring the rollers 12 closer to the cable. At this time, the second knob 14 moves in the second strip hole 151. After the adjustment is appropriate, the operator turns the second knob 14 to control the cable. Finally, the operator operates the electrical cabinet to test the wear resistance life of the car charging cable. During the test, the motor 20 starts and drives the drive wheel 211 to rotate through the reducer. The driven wheel 213 rotates accordingly. The synchronous belt 212 drives the mounting base 8 to move. The two clamping flaps 91 drive the charging head and cable to stretch and retract at the same speed. After the test, the motor 20 is turned off. Example 2

[0024] This embodiment provides a car charging cable testing device. This embodiment is an optimization based on embodiment 1 to improve the technical effect and refine the technical solution. For the contents not described in detail in this embodiment, please refer to embodiment 1.

[0025] Based on Embodiment 1, the difference between this embodiment and Embodiment 1 is that the mounting base 8 is driven onto the test frame 2 by a moving drive unit 19; the moving drive unit 19 includes a motor 20 mounted on the test frame 2, the output shaft of the motor 20 is connected to a lead screw 22, and the mounting base 8 is connected to the lead screw 22 via a transmission connection, which can ensure the uniform speed of stretching and retraction, as well as the stability of repeatability testing. See details below. Figure 8 .

[0026] In one embodiment of this utility model, the lead wire assembly 6 is further provided with a limiting component 23. The limiting component 23 includes a fixing block 24. One end of the fixing block 24 is rotatably connected to the upper part of the support rod 13, and the other end of the fixing block 24 is connected to a connecting shaft. The connecting shaft is fixed to the fixing block 24 installed on another support rod 13 by a pin. A roller 25 is fitted on the connecting shaft, and the roller 25 rotates relative to the connecting shaft to further control the position of the cable and prevent the cable from slipping off the test frame 2 during the test, thus affecting the test results. See details below. Figure 6 .

[0027] like Figure 6 , Figure 8 As shown, the wear resistance life of the car charging cable is tested. After adjusting the test frame 2, charging head, and cable, the connecting shaft is rotated close to the fixing block 24. The fixing block 24 and the connecting shaft are fixed by the pin to further control the cable. During the connection test, the motor 20 is started, which drives the lead screw 22 to rotate. The lead screw 22 drives the mounting seat 8 to move through the lead screw nut. The clamp 9 drives the charging head and cable to stretch and retract at the same speed. The roller 25 rotates around the connecting shaft to avoid damaging the cable. After the test, the motor 20 is turned off.
