DETAILED DESCRIPTION

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0023] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 A new energy vehicle charging pile component detection device includes a temperature control chamber 4 with a built-in fixed head 1, a pressure head 2 and a connecting head 3. The fixed head 1 is provided with a plurality of fixed heads, and two fixed heads 1 form a fixed unit. The two fixed heads 1 in the fixed unit fix the charging gun 6 from the left and right ends of the charging gun 6 respectively. The pressure head 2 moves up and down and is connected to the temperature control chamber 4 and is located above the charging gun 6. A linkage mechanism 8 is provided between the pressure head 2 and the fixed head 1. The fixed head 1 is installed in the temperature control chamber 4 through a base 7. Figure 2 and Figure 5As shown, the fixed head 1 is connected to the base 7 with a left-right limit sliding connection, and the base 7 is connected to the temperature control chamber 4 with a left-right limit sliding connection. The base 7 can be controlled to move left and right by an electric screw, and an elastic suppression member 5 is provided on the base 7 to suppress the initial position state of the fixed head 1. In the initial state, the fixed heads 1 at the left and right ends of the charging gun 6 are both in fixed positions. At this time, the left and right fixed heads 1 can accurately clamp and fix the two ends of the charging gun 6, and the fixed head 1 at the left end of the charging gun 6 can slide to the left, and the fixed head 1 at the right end can slide to the right. The connector 3 is fixedly installed in the temperature control chamber 4 and is located on the right side of the charging gun 6. The rightward movement of the base 7 can make the charging gun 6 fixed by the fixed head 1 plugged into the connector 3, and the connectivity state of the charging gun 6 is detected. In the detection process of the present invention, the charging gun 6 is first fixed from both ends of the charging gun 6 by the fixing head 1, and then the pressure head 2 moves up and down to apply pressure to the charging gun 6 in an intermittent manner, and in this process, the fixing head 1 is intermittently pushed to both sides by the linkage mechanism 8, and a pulling force is applied to the charging gun 6 by the fixing head 1, and the pressure and the pulling force are not applied to the charging gun 6 at the same time. The number of times the pressure and the pulling force act on the charging gun 6 is set according to the specific situation of the detection, and the set number of times is a force application unit. After each force application unit is completed, a connection state detection is performed, that is, the base is moved to the right. 7 connects the charging gun 6 to the connector 3, and then resets the base 7 to continue to enter the next force application unit, so that the mechanical properties of the charging gun 6 are quickly and conveniently tested from the two aspects of tensile strength and compressive strength in this cycle, and whether the mechanical properties of the charging gun 6 are qualified is determined according to the test results. If the connection state of the charging gun 6 is normal and the appearance is not damaged after the test, it indicates that the production is qualified, otherwise it is unqualified. Among them, the temperature control chamber 4 can control the temperature of the test environment to detect whether the mechanical properties of the charging gun 6 are qualified under different temperature environments, which is conducive to improving the reliability of the test results. Among them, the fixed head 1 includes two upper and lower clamping heads, the lower clamping head is slidably connected to the base 7, and the upper clamping head is slidably connected to the lower clamping head, and the upper and lower clamping heads are in contact with the charging gun 6. The surface is set according to the structure of the corresponding area of ​​the charging gun 6, which can stably clamp and fix the charging gun 6.

[0024] See also Figure 2 , Figure 3 and Figure 4 The linkage mechanism 8 includes a push head 81 mounted on the pressure head 2 and a socket head 82 elastically slidably connected to the fixed head 1. The push head 81 corresponds to the socket head 82 one by one. Figure 3As shown, the socket joint 82 on the left fixed head 1 is located on the right side of the left fixed head 1, and the socket joint 82 on the right fixed head 1 is located on the left side of the right fixed head 1, and the socket joints 82 on the fixed head 1 are symmetrically distributed front to back and are respectively located on the front and back sides of the corresponding ends of the charging gun 6, and the socket joints 82 are symmetrically arranged with inclined receiving surfaces 83 from top to bottom, and an arc-shaped transition surface 84 is arranged between the upper and lower symmetrical receiving surfaces 83, and the arc-shaped transition surface 84 and the upper and lower symmetrical receiving surfaces 83 constitute a complete contact surface, and the push head 81 is a connecting arm 812 rotatably connected to the contact wheel 811, and the connecting arm 812 is fixedly connected to the pressure head 2. During the up and down movement of the pressure head 2, the contact wheel 811 intermittently moves along the contact surface and pushes the socket joint 82 to apply thrust to the corresponding fixed head 1, and applies pulling force to the charging gun 6 through the fixed head 1. As shown Figure 4 As shown, during the downward movement of the pressure head 2, the contact wheel 811 on the left contacts the contact surface on the left socket head 82, and during the downward movement, the left socket head 82 is first pushed to the left to apply a leftward thrust to the left fixed head 1, and then the thrust applied to the fixed head 1 is smoothly released. Similarly, the contact wheel 811 on the right contacts the contact surface on the right socket head 82 to apply a rightward thrust to the right fixed head 1, thereby forming two pulling forces acting on the charging gun 6. After the thrust on the fixed head 1 is smoothly released, as the pressure head 2 continues to move downward, the pressure head 2 applies pressure to the charging gun 6, and then the pressure head 2 moves upward and resets to release the pressure. During this process, pulling force is applied to the charging gun 6 again, and when the pressure head 2 resets and moves to the starting point, the contact wheel 811 and the socket head 82 are completely offset. At this time, the base 7 can be smoothly moved to the right to connect the charging gun 6 with the connector 3 for connection status detection. The entire detection process tests the mechanical properties of the charging gun 6 from both compression and tension aspects. It is not only fast and efficient, but also has high fluency and continuity in the entire detection process, which helps to further improve the efficiency of the detection as well as the stability and reliability of the detection process.
