[0003] In the related art, the stress durability of the charging product is mainly tested by artificial stepping. The working efficiency is low, and the test precision is not high. UTILITY MODEL CONTENT

[0004] Embodiments of the present application provide a testing device, which can solve the problem of low working efficiency and low test precision when artificial stepping is tested.

[0005] Embodiments of the present application provide a testing device, which can solve the problem of low working efficiency and low test precision when artificial stepping is tested.

[0006] A support is provided.

[0007] A rotating member is arranged on the support.

[0008] A driving member is connected with the rotating member and used to drive the rotating member to rotate.

[0009] A counterweight is arranged on the support. When the driving member drives the rotating member to rotate, the support drives the counterweight to reciprocate along a first direction.

[0010] In the technical scheme of the embodiments of the present application, when the driving member drives the rotating member to rotate, the support can drive the counterweight to reciprocate along the first direction. When the counterweight reciprocates along the first direction, the counterweight can simulate the stepping test. The whole process does not need manual intervention, has high automation, and greatly improves the test efficiency. Moreover, since the stepping position of the counterweight acting on the to-be-tested object does not change, the force position exerted by the counterweight on the to-be-tested object is the same each time, so that the test precision can be improved.

[0011] In some examples, the weight and size of the counterweight are adjustable. Since the weight and size of the counterweight are adjustable, the weight and size of the counterweight can be adjusted according to actual conditions to achieve different force values and force areas, so as to facilitate different test requirements.

[0012] In some implementations, the support includes a first support rod, a hanging arm, and a second support rod.

[0014] The rotating member is arranged on the second support rod, and the rotating member is in contact with the cantilever arm;

[0015] When the driving member drives the rotating member to rotate, the rotating member drives the cantilever arm to reciprocate along the first direction relative to the first support rod, wherein the second direction intersects the first direction. In this way, the rotating member can drive the cantilever arm to reciprocate along the first direction by driving the driving member to rotate, and since the counterweight is connected to the cantilever arm, the counterweight can reciprocate along the first direction synchronously when the cantilever arm reciprocates along the first direction.

[0016] In some implementations, the rotating member includes an eccentric wheel, and the eccentric wheel is rotationally connected to the second support rod;

[0017] The driving member is connected to the eccentric wheel to drive the eccentric wheel to rotate, and the eccentric wheel drives the cantilever arm to reciprocate along the first direction relative to the first support rod when the eccentric wheel rotates. In this way, the driving member can conveniently drive the cantilever arm to reciprocate along the first direction by driving the eccentric wheel to rotate.

[0018] In some implementations, the rotating member further includes a pulley, the pulley is rotationally connected to the cantilever arm, and the pulley cooperates with the eccentric wheel. In this way, the pulley rotates synchronously when the eccentric wheel rotates, thereby avoiding friction between the cantilever arm and the eccentric wheel.

[0019] In some implementations, the support further includes a base;

[0020] The first support rod and the second support rod are spaced apart along a second direction; one end of the cantilever arm is rotationally connected to the first support rod, and the other end of the cantilever arm is connected to the counterweight;

[0021] In some implementations, the test device further includes a control module, the control module is electrically connected to the driving member to control the opening and closing of the driving member. In this way, the control module can control the number of rotations of the driving member, thereby conveniently controlling the number of times the counterweight is raised and lowered, and further conveniently controlling the number of times the counterweight acts on the cable to be tested to meet the test requirements.

[0022] In some implementations, the testing device further comprises a lifting platform, the lifting platform at least partially overlaps with the projection of the counterweight in the first direction, and the lifting platform is configured to drive the cable to be tested to reciprocate in the first direction. In this way, the height difference between the cable to be tested and the counterweight can be adjusted by the lifting platform to meet the testing requirements. At the same time, when the cable to be tested needs to be placed or taken out, the cable to be tested only needs to be driven away from the counterweight by the lifting platform, and the whole process does not need to manually move the counterweight, thereby effectively saving manpower.

[0023] In some implementations, the testing device further comprises a connecting piece, one end of the connecting piece is connected with the end of the boom away from the first support rod, and the other end of the connecting piece is connected with the counterweight. In this way, the counterweight and the boom are conveniently connected.

[0040] The new energy charging terminal generally includes a charging gun and a charging pile, wherein the charging gun includes a charging gun body and a charging cable. The cable will be stepped on in the charging scene, and once the durability of the cable is unqualified, it is easy to cause a safety accident.

[0041] An embodiment of the present application provides a test device which can be applied to the voltage resistance performance test of the charging cable. In other scenarios, the test device provided by the embodiment of the present application can also be applied to the voltage resistance performance test of other types of cable products, for example: data line, power line, and other products that may be involved in the stepped-on scene, or applied to scientific research experiments as a standardized and automated mechanical test tool to help researchers study the mechanical properties of various articles. In order to facilitate the description, the application to the voltage resistance performance test of the charging cable is taken as an example for description.

[0042] As shown in Figure 1 and shown in Figure 2 , the test device includes a support 11, a driving member 12, a rotating member 13 and a counterweight 14, wherein the rotating member 13 is arranged on the support 11, the driving member 12 is connected with the rotating member 13 and is used to drive the rotating member 13 to rotate, and the counterweight 14 is arranged on the support 11. Under the condition that the driving member 12 drives the rotating member 13 to rotate, the support 11 drives the counterweight 14 to reciprocate along a first direction.

[0043] In some examples, the first direction is the height direction of the support 11. For example, the first direction in the embodiment is the height direction of the support 11 as shown in Figure 1X-axis direction in the figure.

[0044] The driving member 12 in the embodiment can be a motor, a hydraulic transmission motor, etc. The specific type can be determined according to actual conditions, and the embodiment of the specification does not limit this.

[0045] The rotating member 13 in the embodiment can be a cam mechanism, an eccentric mechanism, etc. The specific type can be determined according to actual conditions, and the embodiment of the specification does not limit this.

[0046] The counterweight 14 in the embodiment can be circular, square, etc. The overall weight of the counterweight 14 can be about 750N, 880N, etc. The material of the counterweight 14 can be plastic, rubber, metal, etc.

[0047] In some examples, the weight and size of the counterweight 14 can be adjusted.

[0048] The counterweight 14 in the embodiment can be composed of multiple individual weight blocks. By combining different types and sizes of weight blocks together, the weight and size of the counterweight 14 can be adjusted.

[0049] In the embodiment, the weight and size of the counterweight 14 can be adjusted according to actual conditions to achieve different force values and force areas, thereby facilitating the satisfaction of different test requirements.

[0050] During testing, after the bracket 11, the driving member 12, the rotating member 13, and the counterweight 14 are all installed, the cable to be tested 10 is placed directly below the counterweight 14 along the X-axis direction. Then, the driving member 12 drives the rotating member 13 to rotate. At this time, the bracket 11 drives the counterweight 14 to reciprocate along the X-axis direction. When the counterweight 14 moves downward along the X-axis direction, the counterweight 14 can step on the cable to be tested 10.

[0051] In the technical solution of the embodiment of the application, when the driving member 12 drives the rotating member 13 to rotate, the bracket 11 drives the counterweight 14 to reciprocate along the X-axis direction. When the counterweight 14 reciprocates along the X-axis direction, the counterweight 14 can simulate the stepping test. The overall process does not require manual intervention, has high automation, and greatly improves the test efficiency. Moreover, since the overall weight of the counterweight 14 is controllable, and the stepping position of the counterweight 14 on the cable to be tested 10 does not change, the size and position of the force exerted by the counterweight 14 on the cable to be tested 10 are the same each time, thereby improving the test accuracy. At the same time, the test device in the embodiment has a simple structure and is easy to manufacture, thereby effectively reducing the cost.

[0052] According to some embodiments of the application, as Figure 1As shown, the support 11 comprises a first support rod 112, a cantilever arm 113 and a second support rod 114, wherein the first support rod 112 and the second support rod 114 are spaced apart along a second direction, one end of the cantilever arm 113 is rotationally connected with the first support rod 112, and the other end of the cantilever arm 113 is connected with the counterweight 14; the rotating member 13 is arranged on the second support rod 114, and the rotating member 13 is in contact with the cantilever arm 113; under the condition that the driving member 12 drives the rotating member 13 to rotate, the rotating member 13 drives the cantilever arm 113 to reciprocate along a first direction relative to the first support rod 112, wherein the second direction intersects the first direction.

[0053] In the embodiment, as shown in Figure 1 the second direction is the Y-axis direction, wherein the included angle between the X-axis and the Y-axis can be about 80°, 85°, 90°, etc., and the embodiment is described by taking the case that the X-axis and the Y-axis are perpendicular to each other as an example.

[0054] The cantilever arm 113 and the first support rod 112 in the embodiment can be connected through a rotating shaft, or the cantilever arm 113 and the first support rod 112 are connected through a bearing, and the specific connection mode can be determined according to actual conditions, and the embodiment of the specification does not limit the connection mode.

[0055] Referring to Figure 1 In the embodiment, one end of the cantilever arm 113 and the first support rod 112 are rotationally connected towards one end of the cantilever arm 113, and the rotating member 13 is arranged on one end of the second support rod 114 towards the cantilever arm 113. Of course, it can be understood that one end of the cantilever arm 113 can also be connected with the middle part of the first support rod 112, and the rotating member 13 can also be arranged at other positions of the second support rod 114. The specific arrangement mode can be determined according to actual conditions, and the embodiment of the specification does not limit the arrangement mode.

[0056] The length of the second support rod 114 in the embodiment is less than the length of the first support rod 112. Of course, it can be understood that the length of the second support rod 114 can also be greater than or equal to the length of the first support rod 112. The specific length can be determined according to actual conditions, and the embodiment of the specification does not limit the length.

[0057] Referring to Figure 1 In the embodiment, the second support rod 114 is arranged on the left side of the first support rod 112, and the length of the second support rod 114 along the X-axis direction is less than the length of the first support rod 112 along the X-axis direction. The right end of the cantilever arm 113 is connected with the first support rod 112 through a rotating shaft, and the left end of the cantilever arm 113 is connected with the counterweight 14. The second support rod 114 is located at the middle position below the cantilever arm 113, and the upper end of the second support rod 114 is connected with the rotating member 13 through a rotating shaft.

[0058] In use, the rotating member 13 is driven to rotate by the driving member 12, and the boom 113 is driven to reciprocate along the first direction by the rotating member 13. Since the counterweight 14 is connected to the boom 113, the counterweight 14 is driven to reciprocate along the first direction synchronously with the boom 113.

[0059] It should be noted that the structure of the bracket is only an example, and other structures can also be used in alternative solutions, for example, the bracket further includes a support seat, and the first support rod and the second support rod are both fixed on the support seat. The specific structure of the bracket is not specially limited in the application, as long as the above structure can achieve the purpose of the application.

[0060] According to some embodiments of the application, as shown in Figure 1 or Figure 2 The rotating member 13 includes an eccentric wheel 131, and the eccentric wheel 131 is rotationally connected to the second support rod 114. The driving member 12 is connected to the eccentric wheel 131 and is used to drive the eccentric wheel 131 to rotate. Under the condition that the eccentric wheel 131 rotates, the eccentric wheel 131 drives the boom 113 to reciprocate along the first direction relative to the first support rod 112.

[0061] The eccentric wheel 131 in the embodiment is connected to one end of the second support rod 114 facing the boom 113. Of course, it can be understood that the eccentric wheel 131 can also be connected to other positions of the second support rod 114, and the specific position can be determined according to the actual situation, and the embodiment of the specification is not limited in this regard.

[0062] The eccentric wheel 131 in the embodiment is connected to the upper end of the second support rod 114 along the X-axis direction through a rotating shaft, a bearing or the like, and the specific connection manner can be determined according to the actual situation, and the embodiment of the specification is not limited in this regard.

[0063] In the embodiment, the eccentric wheel 131 is fixed on the output shaft of the driving member 12, and the driving member 12 can drive the eccentric wheel 131 to rotate.

[0064] In use, since the eccentric wheel 131 is in contact with the boom 113, when the driving member 12 drives the eccentric wheel 131 to rotate, the eccentric wheel 131 will reciprocate along the X-axis direction relative to the boom 113 under the limitation of the structure of the eccentric wheel 131 itself. At this time, the boom 113 moves synchronously with the eccentric wheel 131, so as to realize the reciprocating movement of the boom 113 along the X-axis direction.

[0065] According to some embodiments of the application, as shown in Figure 1 The rotating member 13 further includes a pulley 132, which is rotationally connected to the boom 113 and cooperates with the eccentric wheel 131.

[0066] The pulley 132 in the embodiment can be connected to the boom 113 through a rotating shaft, a bearing or the like. The specific connection manner can be determined according to actual conditions, and the embodiment of the specification does not limit the connection manner.

[0067] In use, when the eccentric wheel 131 rotates, the pulley 132 synchronously rotates. Since the pulley 132 is connected to the boom 113, when the eccentric wheel 131 reciprocates along the X-axis direction, the boom 113 can be driven to reciprocate along the X-axis direction through the pulley 132, so as to avoid damage of the boom 113 caused by friction between the boom 113 and the eccentric wheel 131.

[0068] According to some embodiments of the present application, as shown in Figure 1 The first support rod 112 and the second support rod 114 are both fixed to the base 111.

[0069] As shown in Figure 1 The lower end of the first support rod 112 and the lower end of the second support rod 114 can be integrally formed with the base 111, or the lower end of the first support rod 112 can be connected to the base 111 through a bolt. The specific connection manner can be determined according to actual conditions, and the embodiment of the specification does not limit the connection manner.

[0070] The base 111 can be used to conveniently fix the first support rod 112 and the second support rod 114, so as to stabilize the structure of the overall test device and facilitate use of the overall test device.

[0071] According to some embodiments of the present application, as shown in Figure 1 Or Figure 2 The test device further includes a control module 15 electrically connected to the driving member 12 and configured to control opening and closing of the driving member 12.

[0072] The control module 15 can be a PLC controller, a microcontroller or the like. The specific type of the control module 15 can be determined according to actual conditions, and the embodiment of the specification does not limit the type of the control module 15.

[0073] The control module 15 can be fixed to the driving member 12 through a bolt, or the control module 15 can be fixed to the eccentric wheel 131 through a bolt. The specific fixing manner can be determined according to actual conditions, and the embodiment of the specification does not limit the fixing manner.

[0074] In use, the number of rotations of the eccentric wheel 131 can be conveniently controlled by controlling the number of rotations of the driving member 12, and since the eccentric wheel 131 is in contact with the boom 113 through the pulley 132 and the counterweight 14 is connected to the boom 113, the number of reciprocating movements of the counterweight 14 along the X-axis direction is also controllable when the number of rotations of the eccentric wheel 131 is controllable, and the number of forces of the counterweight 14 acting on the cable to be tested 10 is also conveniently controlled, so as to meet the test requirements.

[0075] According to some embodiments of the present application, as shown in Figure 1 or Figure 2 The test device further comprises a lifting platform 16, which at least partially overlaps with the projection of the counterweight 14 in the first direction, and the lifting platform 16 is used to drive the cable to be tested 10 to reciprocate along the first direction.

[0076] Referring to Figure 1 or Figure 2 In the present embodiment, the lifting platform 16 is located below the counterweight 14.

[0077] The lifting platform 16 in the present embodiment can be a hydraulic lifting platform, an electric lifting platform, etc., which can be determined according to actual conditions, and the present specification embodiments do not limit this.

[0078] In use, the height difference between the cable to be tested 10 and the counterweight 14 can be conveniently adjusted by the lifting platform 16 in order to meet the test requirements. At the same time, when the cable to be tested 10 needs to be placed or taken out, the cable to be tested 10 only needs to be driven away from the counterweight 14 by the lifting platform 16, and the overall process does not need to manually move the counterweight 14, thereby effectively saving manpower.

[0079] According to some embodiments of the present application, as shown in Figure 1 or Figure 2 The test device further comprises a connecting member 17, one end of which is connected to the end of the boom 113 away from the first support rod 112, and the other end of which is connected to the counterweight 14.

[0080] The connecting member 17 in the present embodiment can be a flexible sling, a steel wire rope, etc., which can be determined according to actual conditions, and the present specification embodiments do not limit this.

[0081] Referring to Figure 1 When the counterweight 14 is not in contact with the cable to be tested 10, the connecting member 17 is in a straightened state as a whole; referring to Figure 2 When the counterweight 14 acts on the cable to be tested 10, the connecting member 17 is in a bent state after being subjected to the reaction force of the counterweight 14.

[0082] The present embodiment is provided with the connecting member 17, thereby conveniently connecting the counterweight 14 to the boom 113.

[0083] According to some embodiments of the present application, as shown in Figure 1 or Figure 2 The test device further comprises a first hook 18 arranged at the end of the boom 113 away from the first support rod 112, for connecting with the connecting piece 17.

[0084] The first hook 18 in the embodiment can be integrally formed with the boom 113, or the first hook 18 is fixed on the boom 113 through a pin shaft. The specific method can be determined according to the actual situation, and the embodiment of the present specification does not limit it.

[0085] Referring to Figure 1 As the first hook 18 is fixed on the boom 113, the connecting piece 17 can be connected with the boom 113 by only being hung on the first hook 18.

[0086] According to some embodiments of the present application, as shown in Figure 1 or Figure 2 The test device further comprises a second hook 19 arranged on the counterweight 14, for connecting with the connecting piece 17.

[0087] The second hook 19 in the embodiment can be integrally formed with the counterweight 14, or the second hook 19 is fixed on the counterweight 14 through a pin shaft. The specific method can be determined according to the actual situation, and the embodiment of the present specification does not limit it.

[0088] Referring to Figure 1 As the second hook 19 is fixed on the counterweight 14, the connecting piece 17 can be connected with the counterweight 14 by only being hung on the second hook 19.

[0089] Referring to Figure 1 and Figure 2 When the stepped length of the cable to be tested 10 is 88mm, the stepping force is 750N, and the stepping times are 5000 times, the automatic test of the cable to be tested 10 can be realized by the following steps:

[0090] First step: the total weight of the counterweight 14 is 750N by combining the weight blocks, and the weight block at the bottom of the counterweight 14 is a cylinder with a diameter greater than or equal to 88mm;

[0091] Second step: hang the counterweight 14 on the boom 113 through the connecting piece 17, lower the height of the lifting platform 16, so that the counterweight 14 is suspended as a whole, and then place the cable to be tested 10 on the lifting platform 16;

[0092] Third step: adjust the height of the lifting platform 16 so that the distance between the cable 10 to be tested and the counterweight 14 on the lifting platform 16 reaches the required distance;

[0093] Fourth step: set the number of rotations of the driving member 12 to 5000 times through the control module 15, and start the driving member 12 for testing. Wherein, the driving member 12 rotates once, the eccentric wheel 131 rotates one circle, and the counterweight 14 moves up and down once;

[0094] Fifth step: after the test, lower the lifting platform 16 and take out the cable 10 to be tested.

[0095] When the stepped length of the cable 10 to be tested is 98mm, the stepping force is 880N, and the stepping times are 2000 times, the automatic test of the cable 10 to be tested can be realized through the following steps:

At this time, the number of rotations of the driving piece 12 is set through the control module 15, then the driving piece 12 is started, the driving piece 12 drives the eccentric wheel 131 to reciprocate, the eccentric wheel 131 drives the counterweight 14 to reciprocate along the X-axis direction through the pulley 132, the lifting arm 113 and the connecting piece 17. When the counterweight 14 reciprocates along the X-axis, the counterweight 14 can perform the treading test on the cable to be tested 10. The whole process does not need manual intervention, the automation degree is high, and the test efficiency is greatly improved. Moreover, since the overall weight of the counterweight 14 is controllable, and the treading position of the counterweight 14 on the cable to be tested 10 does not change, the size and position of the force exerted by the counterweight 14 on the cable to be tested 10 are the same each time, so that the test precision can be improved.
