Technical Field
[0001] This utility model relates to the technical field of insertion and extraction force detection devices, specifically a device for detecting the insertion and extraction force of a charging pile charging interface. Background Technology
[0002] A charging pile charging interface insertion and extraction force detection device is mainly used to test the insertion and extraction force of the charging interface to ensure that the charging interface meets safety and operation specifications. Generally, a driving device simulates the insertion and extraction process of the charging pile. The charging interface is contacted by a force sensor, and the insertion and extraction force generated during insertion and extraction is monitored in real time. This device is widely used in the fields of charging pile production, quality inspection, maintenance, and technical research. By detecting the insertion and extraction force, it can effectively determine whether the charging interface meets the specifications, ensuring charging safety and ease of use.
[0003] Utility model patent CN222505661U discloses a device for detecting the insertion and extraction force of a charging pile plug port. The device includes a detection plate and a base plate that are parallel to each other. A detection groove along the axis is formed on the top surface of the detection plate, and a first centering chuck is provided within the groove, clamping the charging pile plug port. An electric push rod is also provided on the top surface of the detection plate, with its lifting direction perpendicular to the detection plate. A connecting shaft is fixed to the transmission end of the electric push rod, and a second centering chuck is provided at the end of the connecting shaft. The second centering chuck is located directly above the first centering chuck, and its clamping surface is mirror-symmetrical to the clamping surface of the first centering chuck. A tension sensor is also provided on the top surface of the detection plate. The input interface of the tension sensor is fixed to the connecting shaft via a pull rod. The pull rod acts on the tension sensor, and the tension sensor signal is output to a display screen. This utility model can intuitively display the insertion and extraction performance of the charging pile plug port on the display screen.
[0004] However, existing charging pile charging interface insertion and extraction force testing devices are difficult to reduce the clamping impact on the test charging connector during use, resulting in scratches or structural deformation on the connector surface caused by rigid clamping, making the sample unusable for other reliability tests after the test. Utility Model Content
[0005] This utility model provides a charging pile charging interface insertion and extraction force testing device, which has the advantage of easily reducing the clamping impact on the test charging connector. This solves the problem that existing charging pile charging interface insertion and extraction force testing devices are difficult to reduce the clamping impact on the test charging connector during use, resulting in scratches or structural deformation of the connector surface caused by rigid clamping, and the sample cannot be used for other reliability tests after testing.
[0006] To facilitate the reduction of clamping impact on the test charging connector, this utility model provides the following technical solution: a charging pile charging interface insertion and extraction force detection device, including a machine base and a fixed base disposed on the top surface of the machine base. Two sets of sliders are fixedly connected to the top of the fixed base. The device also includes: a fixed frame disposed on the top surface of the sliders, a support plate slidably connected inside the fixed frame, and a support assembly fixedly connected to the surface of the support plate. The support assembly includes a base plate, a damping hydraulic rod, and a buffer spring. A clamp is fixedly connected to the top of the buffer spring. A support seat is disposed on the top of the machine base, and a movable seat is slidably connected to the top of the support seat. Four sets of sockets are sleeved on one side of the movable seat. A limit assembly is inserted inside each socket, and the limit assembly includes a plug rod, a support spring, and a locking block. A pressure sensor is disposed on one side of the movable seat, and a positioning seat is fixedly connected to one end of the pressure sensor.
[0007] As a preferred embodiment of this utility model, the support assembly includes a base plate fixedly connected to the surface of the support plate, and two sets of damping hydraulic rods are fixedly connected to the top surface of the base plate, with buffer springs sleeved on the surface of the damping hydraulic rods.
[0008] As a preferred embodiment of this utility model, the limiting component includes a plug rod inserted into the socket, a support spring sleeved on the surface of the plug rod, and two sets of locking blocks fixedly connected to one end of the support spring.
[0009] As a preferred embodiment of this utility model, a connecting plate is slidably connected to the surface of the insertion rod, and a test interface is fixedly connected to one side of the connecting plate.
[0010] As a preferred embodiment of this utility model, a push block is fixedly connected to the bottom of the fixed frame, a threaded rod is threadedly connected to the inside of the push block, and a drive motor is fixedly connected to one end of the threaded rod.
[0011] As a preferred embodiment of this utility model, both sides of the clamp are slidably connected to limit rods, and the limit rods are fixedly connected to the top surface of the base plate.
[0012] As a preferred embodiment of this utility model, a telescopic cylinder is fixedly connected to the surface of the support plate, and a protective pad is fixedly connected to the top of the clamp.
[0013] As a preferred embodiment of this utility model, a support wall is fixedly connected to one side of the top surface of the machine platform, and a control panel is provided on the surface of the support wall.
[0014] Compared with the prior art, this utility model provides a charging pile charging interface insertion and extraction force detection device, which has the following beneficial effects:
[0015] This charging pile charging interface insertion and extraction force testing device, through the setting of the support components, places the charging connector between two sets of clamps during use, and then activates the telescopic cylinder, which pushes the support plate to slide inside the fixed frame. This causes the clamps to pressurize and clamp the charging connector, causing the clamps to squeeze the damping hydraulic rod. The damping hydraulic rod contracts under force, and the buffer spring deforms under force to generate elastic force. At the same time, the protective pad is made of rubber, which has protective capabilities, thereby reducing the impact of clamping on the test charging connector and avoiding scratches or structural deformation of the connector surface caused by rigid clamping. This ensures that the sample can continue to be used for other reliability tests after the test.
[0016] This charging pile charging interface insertion and extraction force detection device, through the setting of the limit component, when it is necessary to disassemble the test interface, first squeeze the plug rod, the support spring is compressed under force, so that the plug rod drives the locking block to slide in the socket, and then the locking block disengages from the internal slot of the socket. Then, the plug rod is rotated, so that the locking block is pulled out along the opening of the socket, thereby achieving the effect of convenient disassembly and assembly of the test interface, realizing tool-free disassembly of the test interface, thus greatly reducing the time spent on replacing different models of charging interfaces and improving the convenience of replacement.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-4 This utility model discloses a charging pile charging interface insertion and extraction force detection device, including a machine base 1 and a fixed base 2 set on the top surface of the machine base 1. Two sets of sliders 3 are fixedly connected to the top of the fixed base 2. It also includes: a fixed frame 4 set on the top surface of the sliders 3, a support plate 5 slidably connected inside the fixed frame 4, a support component 6 fixedly connected to the surface of the support plate 5, the support component 6 including a base plate 601, a damping hydraulic rod 602 and a buffer spring 603, a clamp 7 fixedly connected to the top of the buffer spring 603; a support seat 8 set on the top of the machine base 1, a movable seat 9 slidably connected to the top of the support seat 8, four sets of sockets 10 sleeved on one side of the movable seat 9, a limit component 11 inserted inside the socket 10, the limit component 11 including a plug rod 1101, a support spring 1102 and a locking block 1103; a pressure sensor 12 set on one side of the movable seat 9, a positioning seat 13 fixedly connected to one end of the pressure sensor 12.
[0024] Specifically, the support assembly 6 includes a base plate 601 fixedly connected to the surface of the support plate 5. Two sets of damping hydraulic rods 602 are fixedly connected to the top surface of the base plate 601, and buffer springs 603 are sleeved on the surface of the damping hydraulic rods 602.
[0025] In this embodiment, during use, the charging connector is placed between the two sets of clamps 7, and then the telescopic cylinder 20 is activated, causing the telescopic cylinder 20 to push the support plate 5 to slide inside the fixed frame 4, thereby driving the clamps 7 to pressurize and clamp the charging connector, causing the clamps 7 to squeeze the damping hydraulic rod 602, causing the damping hydraulic rod 602 to contract under force, and the buffer spring 603 to deform under force and generate elastic force.
[0026] Specifically, the limiting component 11 includes a plug rod 1101 inserted into the socket 10, a support spring 1102 sleeved on the surface of the plug rod 1101, and two sets of locking blocks 1103 fixedly connected to one end of the support spring 1102.
[0027] In this embodiment, when it is necessary to disassemble the test interface 15, the plug rod 1101 is squeezed first, the support spring 1102 is compressed under force, so that the plug rod 1101 drives the locking block 1103 to slide in the socket 10, and then the locking block 1103 is disengaged from the internal slot of the socket 10. The plug rod 1101 is rotated so that the locking block 1103 is pulled out along the opening of the socket 10.
[0028] Specifically, a connecting plate 14 is slidably connected to the surface of the insertion rod 1101, and a test interface 15 is fixedly connected to one side of the connecting plate 14.
[0029] In this embodiment, the plug 1101 drives the connecting plate 14 to assemble and disassemble the test interface 15; the connecting plate 14 serves as a transition structure and can be adapted to the quick replacement of different models of charging interfaces to meet the requirements of multiple standards testing.
[0030] Specifically, a push block 16 is fixedly connected to the bottom of the fixed frame 4, and a threaded rod 17 is threadedly connected inside the push block 16. A drive motor 18 is fixedly connected to one end of the threaded rod 17.
[0031] In this embodiment, the drive motor 18 converts the rotation of the threaded rod 17 into the linear motion of the push block 16, thereby controlling the displacement of the fixed frame 4 and facilitating the connection and disconnection of the connector.
[0032] Specifically, both sides of the clamp 7 are slidably connected to limit rods 19, which are fixedly connected to the top surface of the base plate 601.
[0033] In this implementation scheme, the limiting rod 19 constrains the movement trajectory of the clamp 7 to prevent lateral displacement when pressure is applied; its rigid fixation to the base plate 601 design can withstand a certain test force without deformation.
[0034] Specifically, a telescopic cylinder 20 is fixedly connected to the surface of the support plate 5, and a protective pad 21 is fixedly connected to the top of the clamp 7.
[0035] In this embodiment, the telescopic cylinder 20 pushes the support plate 5, which in turn drives the clamp 7 to clamp the plug, and the rubber material of the protective pad 21 further protects the interface surface from scratches.
[0036] Specifically, a support wall 22 is fixedly connected to one side of the top surface of the machine 1, and a control panel 23 is provided on the surface of the support wall 22.
[0037] In this embodiment, the support wall 22 provides stable support for the frame of the control panel 23. The control panel 23 integrates a PLC system, which supports test parameter setting and real-time data display.
[0038] The working principle and usage process of this utility model are as follows: In use, the charging connector is placed between the two sets of clamps 7, and then the telescopic cylinder 20 is activated, which pushes the support plate 5 to slide inside the fixed frame 4, thereby driving the clamps 7 to pressurize and clamp the charging connector, causing the clamps 7 to squeeze the damping hydraulic rod 602, causing the damping hydraulic rod 602 to contract under force, and the buffer spring 603 to deform under force and generate elastic force. At the same time, the protective pad 21 is made of rubber and has protective capabilities. When it is necessary to disassemble the test interface 15, the plug rod 1101 is squeezed first, the support spring 1102 is contracted under force, and the plug rod 1101 drives the locking block 1103 to slide in the socket 10, thereby disengaging the locking block 1103 from the internal slot of the socket 10. Then, the plug rod 1101 is rotated, causing the locking block 1103 to be pulled out along the opening of the socket 10.
[0039] In summary, this charging pile charging interface insertion and extraction force testing device, through the setting of the support component 6, reduces the clamping impact on the test charging connector, avoids scratches or structural deformation of the connector surface caused by rigid clamping, and ensures that the sample can continue to be used for other reliability tests after testing; through the setting of the limiting component 11, the test interface 15 can be easily disassembled and assembled, realizing tool-free disassembly of the test interface 15, thereby greatly shortening the time spent replacing different models of charging interfaces and improving the convenience of replacement.
