Description

Technical Field

[0001] This invention relates to the field of charging guns, and more particularly to a charging gun testing platform. Background Technology

[0002] my country's new energy vehicles are booming, especially plug-in hybrid electric vehicles. Plug-in hybrid electric vehicles have relatively large batteries and can run in pure electric mode. When the battery is depleted, they can run in hybrid mode and need to be charged from time to time. During use, the charging gun needs to be plugged in and unplugged multiple times. Therefore, the charging gun plugging and unplugging fatigue durability test is an important reliability test to detect its function and lifespan.

[0003] The number of insertion and removal cycles required in the charging gun insertion and removal fatigue durability test is in the tens of thousands. The insertion and removal test involves two parts: the plug and the socket. The actions include insertion, removal and unlocking of the latch.

[0004] Currently, plug-in / plug-out tests are all performed manually. Workers manually insert the plug into the socket, press the button on the plug to unlock it, and then pull the plug out to complete one plug-in / plug-out test. This process is repeated several times. The plugs and sockets are large in size and weight, and the number of plug-in / plug-out operations required during the test is extremely high. Therefore, the existing manual testing process requires a huge amount of labor.

[0005] Therefore, it is necessary to provide a new charging gun testing platform to solve the above-mentioned technical problems. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a charging gun testing platform that solves the problem of the extremely high number of manual plugging and unplugging operations required in existing tests, thus necessitating a high level of labor intensity in the current manual testing process.

[0007] The charging gun testing platform provided by the present invention includes a test bench and a gun to be tested. A trapezoidal slide is fixed above the test bench, a movable seat is slidably arranged on the trapezoidal slide, and two upright seats are fixed at intervals above the movable seat. Two slide rails, a first clamping block, and a second clamping block are spaced apart between the two stands. The first clamping block is fixed on one of the stands. The two slide rails are fixed between the first clamping block and the other stand. Both slide rails pass through the other second clamping block and are slidably connected to it. A tightening bolt is provided on one side of the second clamping block. The threaded end of the tightening bolt passes through the stand and contacts the surface of the second clamping block. The gun to be tested is located between the first clamping block and the second clamping block. The test bench is fixed to the top of a frame, and two sets of test components are arranged at intervals on the frame.

[0008] In a preferred embodiment, the tightening bolt is threadedly connected to the support.

[0009] In a preferred embodiment, the test assembly includes a first cylinder, a mounting bracket, and a charging gun socket. The first cylinder is mounted on the top of the mounting bracket, and the output end of the first cylinder is fixedly connected to the mounting bracket. The charging gun socket is mounted on the bottom of the mounting bracket and is located directly above the gun under test.

[0010] In a preferred embodiment, a tilting seat is fixed to the top of the mounting bracket, and a data display is mounted on the tilting seat.

[0011] In a preferred embodiment, a test motor is mounted on one side of the mounting bracket, a fixing plate is mounted on the output end of the test motor, and an elastic pressure swing rod is fixed on the fixing plate.

[0012] In a preferred embodiment, the support is provided with an adjustment groove, a threaded rod is movably disposed inside the adjustment groove, an adjustment seat is disposed above the support, the threaded rod passes through the bottom of the adjustment seat, the bottom of the adjustment seat is threadedly connected to the threaded rod, and the bottom of the adjustment seat is slidably connected to the adjustment groove; The adjusting seat is equipped with a first closed half ring on the side near the gun to be tested. An L-shaped mounting seat is fixed on the fixing frame. A connecting pipe is slidably arranged on the L-shaped mounting seat. A second closed half ring is installed on the connecting pipe. The second closed half ring and the first closed half ring are located in the same plane. A second cylinder (36) is installed on the fixing frame (10). The output end of the second cylinder (36) is connected to the connecting pipe (22) through a connecting rod (37). An air inlet pipe is installed inside the connecting pipe, and an air inlet is opened on the surface of the second closed semi-ring. One end of the air inlet pipe is connected to the air inlet, and the other end of the air inlet pipe is connected to the air outlet of the gas pressurization device.

[0013] In a preferred embodiment, the end of the threaded rod away from the gun under test passes through the stand and is fixed with a hexagonal block.

[0014] In a preferred embodiment, sealing gaskets are provided at the top and bottom of both the first and second closed semi-rings.

[0015] In a preferred embodiment, two drive screws are movably mounted on the fixed frame via bearings. Both drive screws pass through the movable seat and are threadedly connected to the movable seat.

[0016] In a preferred embodiment, a first bevel gear is installed on each of the two drive screws, a limit seat is fixed on the test bench, a drive shaft is provided through the limit seat, and the drive shaft and the limit seat are movably connected by a bearing. Two second bevel gears are installed at intervals on the drive shaft, and the two second bevel gears mesh with the two first bevel gears respectively. An adjustment motor is installed on the test bench, and the output end of the adjustment motor is connected to the drive shaft through a coupling.

[0017] The beneficial effects of this invention are: 1. When the insertion and extraction force test is required, the first cylinder is activated to move the charging gun socket downward, so that the plug of the gun to be tested is inserted into the charging gun socket for testing. After the test is completed, the staff only needs to press the button on the plug to unlock the latch, and then activate the first cylinder to move the gun to be tested back to start the next experiment, which greatly reduces the labor intensity that workers need to exert during the testing process. 2. When the plug of the gun under test is inserted into the charging gun socket, the test motor can be started to drive the elastic pressure swing arm to rotate. When the elastic pressure swing arm rotates, it will apply pressure to the gun under test, thereby simulating the bending stress that occurs repeatedly during normal use, and detecting whether the gun under test will have defects such as loose interface, poor contact, cracking or excessive wear after being subjected to bending stress in actual use. 3. After completing the above two tests, the adjustment motor can be started to drive the transmission shaft to rotate. Under the transmission action of the two first bevel gears and the two second bevel gears, the two drive screws rotate simultaneously, driving the moving seat to move stably along the trapezoidal slide. 4. When the gun under test is moved directly below the second charging gun socket, first activate the first cylinder to connect the charging gun socket to the plug of the gun under test. Then activate the second cylinder to move the second sealing half-ring closer to its connection point. Finally, use a wrench to turn the hexagonal block. When the hexagonal block rotates, it can drive the threaded rod to rotate, thereby causing the first sealing half-ring to move closer to the second sealing half-ring. The first sealing half-ring, the second sealing half-ring, and the two sealing gaskets can wrap around the connection between the charging gun socket and the plug of the gun under test, forming a closed area. At this time, high-pressure gas can be added to this closed area through the air inlet pipe to perform a tightness test. In summary, the equipment provided by this invention greatly reduces the labor intensity required by workers during the testing process, and allows for multiple measurements of the gun under test in the same area without requiring workers to move the gun under test multiple times.

[0022] In the specific implementation process, such as Figures 1-8 As shown, the test includes a test bench 1 and a test gun 9. A trapezoidal slide 2 is fixed above the test bench 1. A movable seat 3 is slidably mounted on the trapezoidal slide 2. Two uprights 4 are fixed at intervals above the movable seat 3. Two slide rails 5, a first clamping block 6, and a second clamping block 7 are spaced apart between the two uprights 4. The first clamping block 6 is fixed on one of the uprights 4. The two slide rails 5 are fixed between the first clamping block 6 and the other upright 4. Both slide rails 5 pass through the other second clamping block 7, and the slide rails 5 and the second clamping block 7 are slidably connected. A tightening bolt 8 is provided on one side of the 7. The threaded end of the tightening bolt 8 passes through the stand 4 and contacts the surface of the second clamping block 7. The gun to be tested 9 is located between the first clamping block 6 and the second clamping block 7. The tightening bolt 8 is threadedly connected to the stand 4. When using this equipment, the operator can place the gun to be tested 9 between the first clamping block 6 and the second clamping block 7 along the gap between the two stands 4. Then, by turning the tightening bolt 8 with a wrench, the second clamping block 7 can be moved towards the first clamping block 6. The gun to be tested 9 can be fixed by the second clamping block 7 and the first clamping block 6.

[0023] A mounting frame 10 is fixed on the top of the test bench 1. Two sets of test components are arranged at intervals on the mounting frame 10. The test components include a first cylinder 11, a mounting bracket 12, and a charging gun socket 13. The first cylinder 11 is mounted on the top of the mounting frame 10. The output end of the first cylinder 11 is fixedly connected to the mounting bracket 12. The charging gun socket 13 is mounted on the bottom of the mounting bracket 12. The charging gun socket 13 is located directly above the gun 9 under test. A tilting seat 33 is fixed on the top of the mounting frame 10. A data display 34 is mounted on the tilting seat 33. The data display 34 can be used to facilitate the staff to observe the data detected by the sensor inside the charging gun socket 13 in real time.

[0024] A test motor 14 is installed on one side of the mounting bracket 12. A fixing plate 15 is installed at the output end of the test motor 14. An elastic pressure swing rod 16 is fixed on the fixing plate 15. When the plug of the test gun 9 is inserted into the charging gun socket 13, the test motor 14 can be started to drive the elastic pressure swing rod 16 to rotate. When the elastic pressure swing rod 16 rotates, it will apply pressure to the test gun 9, thereby simulating the bending stress that occurs repeatedly during normal use, and detecting whether the test gun 9 will have defects such as loose interface, poor contact, cracking or excessive wear after being subjected to bending stress in actual use.

[0025] An adjustment groove 17 is provided on the stand 4, and a threaded rod 18 is movably installed inside the adjustment groove 17. An adjustment seat 19 is provided above the stand 4. The threaded rod 18 passes through the bottom of the adjustment seat 19, and the bottom of the adjustment seat 19 is threadedly connected to the threaded rod 18. The end of the threaded rod 18 away from the gun to be tested 9 passes through the stand 4 and is fixed with a hexagonal block 35, which is convenient for the operator to turn the hexagonal block 35 with a wrench. The bottom of the adjustment seat 19 is slidably connected to the adjustment groove 17. A first closed semi-ring 20 is installed on the side of the adjustment seat 19 closest to the gun to be tested 9. An L-shaped mounting seat 21 is fixed on the fixing bracket 10. A connecting pipe 22 is slidably installed on the L-shaped mounting seat 21, and a second sealing ring is installed on the connecting pipe 22. Sealing gaskets 24 are provided at the top and bottom of the closed semi-ring 23, the first closed semi-ring 20, and the second closed semi-ring 23. A pressure sensor for detecting changes in air pressure can be installed inside the second closed semi-ring 23. Since the working principle of the pressure sensor is a mature existing technology, it will not be described in detail here. The second closed semi-ring 23 and the first closed semi-ring 20 are located in the same plane. A second cylinder 36 is installed on the fixing frame 10. The output end of the second cylinder 36 is connected to the connecting pipe 22 through a connecting rod 37. An air inlet pipe 25 is installed inside the connecting pipe 22. An air inlet 26 is opened on the surface of the second closed semi-ring 23. One end of the air inlet pipe 25 is connected to the air inlet 26.

[0026] Two drive screws 27 are movably mounted on the fixed frame 10 via bearings. Both drive screws 27 pass through the movable seat 3 and are threadedly connected to the movable seat 3. A first bevel gear 28 is mounted on each of the two drive screws 27. A limit seat 29 is fixed on the test bench 1. A transmission shaft 30 passes through the limit seat 29 and is movably connected to the limit seat 29 via bearings. Two second bevel gears 31 are installed at intervals on the transmission shaft 30. The two second bevel gears 31 mesh with the two first bevel gears 28 respectively. An adjustment motor 32 is mounted on the test bench 1. The output end of the adjustment motor 32 is connected to the transmission shaft 30 via a coupling. When the adjustment motor 32 is started, it drives the transmission shaft 30 to rotate. Under the transmission action of the two first bevel gears 28 and the two second bevel gears 31, the two drive screws 27 rotate simultaneously, causing the movable seat 3 to move stably along the trapezoidal slide 2.

[0027] The other end of the air inlet pipe 25 is connected to the outlet of the gas pressurization device. When the test gun 9 moves directly below the second charging gun socket 13, the first cylinder 11 is activated to connect the charging gun socket 13 to the plug of the test gun 9. Then, the second cylinder 36 is activated to move the second sealing half ring 23 closer to its connection point. Finally, the hexagonal block 35 is rotated with a wrench. When the hexagonal block 35 rotates, it can drive the threaded rod 18 to rotate, thereby making the first sealing half ring 20 closer to the second sealing half ring 23. The first sealing half ring 20, the second sealing half ring 23 and the two sealing gaskets 24 can wrap the connection part between the charging gun socket 13 and the plug of the test gun 9, forming a closed area. At this time, high-pressure gas can be added to the closed area through the air inlet pipe 25 to perform a tightness test.

[0028] Working principle of the invention: When using this device, the operator can place the gun to be tested 9 between the first clamping block 6 and the second clamping block 7 along the gap between the two uprights 4, and then use a wrench to turn the tightening bolt 8 to push the second clamping block 7 towards the first clamping block 6. The gun to be tested 9 can be fixed by the second clamping block 7 and the first clamping block 6. When a insertion and extraction force test is required, starting the first cylinder 11 will move the charging gun socket 13 downward, thereby allowing the plug of the gun under test 9 to be inserted into the charging gun socket 13 for testing. After the test is completed, the staff only needs to press the button on the plug to unlock the latch, and then start the first cylinder 11 to move the gun under test 9 back to its original position to start the next experiment, which greatly reduces the labor intensity that workers need to exert during the testing process. When the plug of the test gun 9 is inserted into the charging gun socket 13, the test motor 14 can be started to drive the elastic pressure swing arm 16 to rotate. When the elastic pressure swing arm 16 rotates, it will apply pressure to the test gun 9, thereby simulating the bending stress that occurs repeatedly during normal use, and detecting whether the test gun 9 will have defects such as loose interface, poor contact, cracking or excessive wear after being subjected to bending stress in actual use. After completing the above two tests, the adjustment motor 32 can be started to drive the transmission shaft 30 to rotate. Under the transmission action of the two first bevel gears 28 and the two second bevel gears 31, the two drive screws 27 rotate simultaneously, driving the moving seat 3 to move stably along the trapezoidal slide 2. When the test gun 9 is moved directly below the second charging gun socket 13, the first cylinder 11 is activated to connect the charging gun socket 13 to the plug of the test gun 9. Then, the second cylinder 36 is activated to move the second sealing half-ring 23 closer to its connection point. Finally, the hexagonal block 35 is rotated with a wrench. When the hexagonal block 35 rotates, it can drive the threaded rod 18 to rotate, thereby causing the first sealing half-ring 20 to move closer to the second sealing half-ring 23. The first sealing half-ring 20, the second sealing half-ring 23, and the two sealing gaskets 24 can cover the connection between the charging gun socket 13 and the plug of the test gun 9, forming a closed area. At this time, high-pressure gas can be added to this closed area through the air inlet pipe 25 to perform a tightness test. In summary, the equipment provided by this invention greatly reduces the labor intensity required by workers during the testing process, and allows for multiple measurements of the test gun 9 in the same area without requiring workers to move the test gun 9 multiple times.

[0029] The circuits and controls involved in this invention are all existing technologies and will not be described in detail here.
