[0018] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0019] In order to solve the technical problem that it is not only difficult to operate, but also takes more time to re-wind and store after detection due to the influence of cable weight in the action of manually taking the charging gun and inserting it into the socket of the detection device for subsequent detection, the present application provides a high-voltage super-charging detection device, which can realize the action of holding the charging gun and pulling it out of the charging gun socket of the charging pile along the axial direction through the pulling mechanism and the holding assembly, moving a small amplitude and separating from the socket, short-stroke pulling the cable of the charging gun, and then through the socket mechanism, the detection socket is driven to displace between the charging gun and the charging gun socket of the charging pile by the turnover assembly, forming coaxial and sequential arrangement of the charging gun, the detection socket and the charging gun socket, and then cooperating with the pulling mechanism to insert the charging gun into the detection socket, which can be electrically connected to the detection host for subsequent detection, avoiding pulling off the cable of the charging gun, moving the charging gun with a small amplitude, and completing the plug-in detection action, improving the detection efficiency, simplifying the subsequent operation and storage and arrangement, and being applicable to the detection of charging piles before leaving the factory or daily maintenance detection.

[0020] It should be noted that the high-voltage super-charging detection device described in the present application is used for but not limited to high-voltage super-charging charging piles, in order to facilitate the description, in the present application, only the high-voltage super-charging detection device applied to the high-voltage super-charging charging pile is taken as an example for description, and the principle of the high-voltage super-charging detection device applied to other types of devices is substantially the same as that applied to the high-voltage super-charging charging pile, which is not described here.

[0021] Please refer to Figures 1-4The present invention provides a high-voltage supercharging detection device, which includes a detection host 1, a holding mechanism 2 and a socket mechanism 3; the detection host 1 is the detection body, with a built-in BMS simulator, a recorder, and an insulation test module to achieve protocol consistency, interoperability and metrological verification; the holding mechanism 2 includes a pulling mechanism 21 and a holding component 22, the pulling mechanism 21 is installed on one side of the detection host 1, and can perform linear telescopic movements to simulate the movements of pulling, pulling, and inserting a charging gun, the holding component 22 has a clamping claw end for clamping the charging gun, and can perform the clamping movement of the charging gun to simulate the holding movement of the charging gun, the movable end of the pulling mechanism 21 is connected to the holding component 22, and the holding component 22 is driven to move axially along the charging gun socket of the charging pile, thereby forming the movement of pulling or inserting the charging gun; the socket mechanism 3 includes a flip The rotating component 31 and the detection socket 32, the flip component 31 is installed on one side of the detection host 1, and can perform rotation in the vertical plane. The movable end of the flip component 31 is connected to the detection socket 32, and the detection socket 32 ​​is rotated in the vertical plane and moved above or below the holding component 22 and the pulling mechanism 21, leaving linear movement space for the holding component 22 to avoid blocking its linear movement path. Moreover, after the holding component 22 and the pulling mechanism 21 pull out the charging gun, the detection socket 32 ​​can be driven to flip and move to align with the charging pile charging gun socket, so that the charging gun and the detection socket 32 ​​are coaxial, and then pushed by the pulling mechanism 21, it can be inserted into the detection socket 32; the detection socket 32 ​​is electrically connected to the detection host 1, and is used to insert the charging pile charging gun for detection. After the charging gun is inserted, subsequent detection can be performed.

[0022] It is understandable that the detection host 1 uses existing mature detection instruments and electrically connects its detection plug port with the detection socket 32 ​​of the socket mechanism 3 to form the basic model of this detection device. For example, the core device of the detection host 1 can be a XL-942SC super charging pile field comprehensive tester, which can be integrated and installed on the frame of the detection host 1. An adapter is used to connect the charging gun socket of the XL-942SC super charging pile field comprehensive tester and extend it to the connection detection socket 32, thereby forming an electrical connection between the detection host 1 and the detection socket 32, thereby achieving the purpose of subsequent detection.

[0023] It should be noted that, in the assembly of the rack, lightweight materials can be used to form the basic frame, and counterweights can be used to maintain basic structural strength and stability. This facilitates assembly and transportation and use in changing scenarios. In addition, for different testing needs, factory testing or on-site maintenance, the detection host 1 can be assembled in a modular form, corresponding to the existing testing instrument, for adaptive installation, and using the connection mode of the adapter cable, the detection socket 32 ​​can be connected to the socket end of the detection instrument to obtain the device.

[0024] In one embodiment, referring to Figure 1 , Figure 2 and Figure 3 , in order to hold the charging gun and unlock the lock catch thereon, the holding assembly 22 comprises a clamping jaw mechanism 221 mounted at the movable end of the pulling mechanism 21 and a pressing unlocking mechanism 222 mounted on the clamping jaw mechanism 221 and having a pressing end movable axially along the charging gun for pressing and unlocking the lock catch of the charging gun, the clamping jaw mechanism 221 holds the charging gun, and the pressing unlocking mechanism 222 presses the lock catch button of the charging gun to be pressed and unlocked, so that the charging gun can be smoothly inserted and pulled out.

[0025] Specifically, the clamping jaw mechanism 221 comprises an opening and closing driving member 221a, an upper clamping jaw 221b and a lower clamping jaw 221c, the movable end of the opening and closing driving member 221a is connected with the upper clamping jaw 221b and the lower clamping jaw 221c to drive the upper clamping jaw 221b and the lower clamping jaw 221c to close and open.

[0026] It should be noted that the pulling mechanism 21 can adopt a driving mechanism with linear formation such as a pneumatic cylinder push rod, a hydraulic push rod, etc.

[0027] The opening and closing driving member 221a is composed of a fixed frame and two telescopic cylinders, the two telescopic cylinders are respectively hinged at the top and bottom of the fixed frame, the telescopic ends of the telescopic cylinders are respectively hinged with the outer sides of the upper clamping jaw 221b and the lower clamping jaw 221c, and the bottoms of the upper clamping jaw 221b and the lower clamping jaw 221c are hinged with the fixed frame to form a basic opening and closing frame, the telescopic cylinders are telescoped to drive the upper clamping jaw 221b and the lower clamping jaw 221c to open and close, and the upper clamping jaw 221b and the lower clamping jaw 221c are provided with abutting blocks at the ends of the fixed frame for abutting to the side surface of the charging gun to preliminarily position and then close and hold the upper clamping jaw 221b and the lower clamping jaw 221c.

[0028] It should be noted that the opening and closing driving member 221a can also adopt a telescopic mechanism arranged vertically upward and downward to control the clamping and separation of the upper and lower clamping jaws to achieve the purpose of driving the clamping jaws to close and open. In addition, in the operation scheme of the upper and lower clamping, the clamping jaw can be provided with an extension end corresponding to the position of the unlocking button, which directly achieves the purpose of unlocking in the pressing operation.

[0029] Further, in order to adapt to the pressing unlocking of the locking button at different positions, the pressing unlocking mechanism 222 comprises a linear driving member 222a, a telescopic member 222b, and a roller 222c, the roller 222c is rotationally connected to the telescopic end of the telescopic member 222b, the telescopic member 222b drives the roller 222c to press down or lift up, the linear driving member 222a is mounted on the top of the upper jaw 221b through a support, the movable end of the linear driving member 222a is connected with the telescopic member 222b, and drives the telescopic member 222b and the roller 222c to move along the axis of the charging gun. Through linear driving along the axis, the telescopic member 222b can be moved from the side close to the end of the charging gun to the side away from the end, and in the movement process, the telescopic member 222b is in the action of pressing down the roller 222c. In the non-pressing position, the charging gun blocks the telescopic member 222b from continuing to push the roller 222c downward, and in the pressable unlocking position, the telescopic member 222b can continue to push the roller 222c downward to press down the locking button of the charging gun, thereby forming unlocking.

[0030] It can be understood that a pressure sensor can also be installed at the roller 222c, and the driving of the telescopic member 222b is controlled according to pressure feedback. In addition, at the position of pressure mutation, it can be judged whether it is the unlocking button, and then the pulling mechanism 21 is used for pulling. If the pulling stroke can be performed, it is fed back that the unlocking is successful, if the pulling is unsuccessful, the roller 222c is controlled to move again to find the correct pressing position, thereby improving the success rate of pressing.

[0031] It should be noted that the linear driving member 222a can be a cylinder push rod, a hydraulic push rod, or other driving mechanisms with linear formation.

[0032] In one embodiment, please refer to Figure 1 In order to facilitate movement and direct manual movement, the holding mechanism 2 and the socket mechanism 3 are aligned with the charging gun position, a plurality of universal wheels 101 are arranged at the bottom of the detection host 1, and the alignment is performed by manual pushing movement, thereby facilitating operation.

[0033] It should be noted that the universal wheel 101 is a universal wheel 101 with a brake positioning function, so as to avoid slipping during the connection process of detection.

[0034] Further, in order to facilitate leveling and alignment, avoid offset between clamping and socket insertion, and affect socket insertion stability, a flat support 102 is rotationally connected to one side of the detection host 1, and is used for being attached to one side of the charging pile. The side wall of the charging pile is used as a leveling base surface, and the flat support 102 is attached and leveled, thereby facilitating alignment with the charging gun port.

[0035] It can be understood that the flat bracket 102 is a rotary connection with damping on the detection host 1, and can be rotated and extended outside the main body of the detection host 1 when needed, and the flat bracket 102 is parallel to the length direction of the holding assembly 22.

[0036] Further, in order to facilitate lifting and feeding actions and reduce manual operation, the holding mechanism 2 and the socket mechanism 3 are connected with the detection host 1 through a displacement mechanism 4, which has at least a movable end for driving the holding mechanism 2 and the socket mechanism 3 to move in a first direction, driving the holding mechanism 2 and the socket mechanism 3 to adjust the height position, adjusting the height position of the holding mechanism 2 and the socket mechanism 3 to match the charging gun socket at different height positions.

[0037] Further, the displacement mechanism 4 also has a movable end for moving in a second direction, driving the holding mechanism 2 and the socket mechanism 3 to move perpendicular to the first direction, matching the charging gun socket at different distances.

[0038] It can be understood that the displacement mechanism 4 can adopt a controllable linear drive mechanism such as a screw guide rail pair, which can be automatically controlled by a controller, facilitating subsequent automatic detection line processes.

[0039] In one embodiment, please refer to Figure 1 The detection socket 32 is electrically connected to the detection host 1 through a cable 32a, and the end of the cable 32a away from the detection socket 32 can also be provided with an adapter for electrical connection with the detection host 1.

[0040] In one embodiment, the number of holding mechanisms 2 and socket mechanisms 3 is two, which are installed on both sides of the detection host 1, and can simultaneously detect the two sides of the double-gun charging pile, improving the detection efficiency.

[0041] It can be understood that the socket mechanism 3 can also adopt a double-end plug mode, which can adapt to left and right plug-in, and the linear drive member 222a of the pressing unlocking mechanism 222 can be adjusted to a gear and rack drive, and the telescopic member 222b and the roller 222c are installed on the rack, and the gear and the driving motor are installed on the upper clamp jaw, so that the telescopic member 222b and the roller 222c can be driven to move on the left and right sides of the clamp jaw under the double-end switching.

[0042] In order to better understand the present application, the following will be combined Figures 1 to 4 The technical solutions of the present application will be described in detail: in the initial position state, please refer to Figure 4, detects the socket 32 is located above the holding assembly 22, and the turnover assembly 31 also across the telescopic part of the pull mechanism 21, the initial position state, the pull mechanism 21 controllable telescopic movement of holding assembly 22, carry out the pull action, can be attached to the end of the charging gun; when the pull mechanism 21 moves holding assembly 22, then with the jaw mechanism 221 on the charging gun clamping, and then through the press unlocking mechanism 222, linear movement and through the telescopic piece 222b down action, press the lock of the charging gun, then with the pull mechanism 21 pull, the charging gun is pulled out; after pulling out, again through the turnover assembly 31 will detect the socket 32 is rotated to flush with the telescopic axis of the pull mechanism 21, then through the pull mechanism 21 reverse push the charging gun, can be inserted into the detection socket 32, as shown in Figure 3 , after insertion and power supply communication, the subsequent detection can be carried out by the detection host 1.
