[0044] At present, different customers have different requirements for the appearance, functions, etc. of charging and discharging guns. The shell structure of traditional charging and discharging guns is usually an integral design. When it is necessary to meet the diverse needs of different customers, it is often necessary to redesign the entire shell, resulting in high R&D costs and long cycles. Moreover, due to the lack of commonality between different designs, parts cannot be shared, further increasing production costs. Therefore, it is of great practical significance to develop a charging and discharging gun that can be flexibly customized and reduce costs.

[0045] In this example, the tray structure 2, the gun line fixing and anti-dropping structure 8, the gun head 9 and the mechanical lock structure 10 are an immutable module group, which ensures the basic functions and stability of the charging and discharging gun; the gun body shell 1, the light guide column structure 11 and the decorative cover 12 are a variable module group, which can be quickly customized and produced according to different customer needs; the specific decorative cover 12 can be customized with different appearance styles and colors according to customer needs; the light guide column structure 11 can be customized with different shapes and light transmission effects according to customer needs; the gun body shell 1 can be customized with different sizes, shapes and materials according to customer needs. By combining and assembling variable modules and immutable modules, it is possible to quickly customize the design of a new charging and discharging gun to meet diverse needs and realize flexible customized design. The structural design idea is reasonable, has strong practicality and promotion value, reduces production costs and R&D cycles, and can be widely used in the design of various charging pile products, especially for scenarios that need to adapt to multiple technical specifications and multiple appearance requirements.

[0046] The assembly steps of the variable module and the immutable module are as follows: First, pass the gun wire 7 through the interior of the gun body shell 1, and press the terminal head of the gun wire 7 onto the input terminal seat of the PCB module 3; secondly, tighten the gun wire fixing anti-dropping structure 8 according to the length of the gun wire 7; then install the PCB module 3 on the tray structure 2, and then insert the tray structure 2 and the PCB module 3 into the gun body shell 1 along the guide structure in the gun body shell 1, and the installation and fixation can be achieved without using fasteners (such as screws); then insert the gun head 9 into the copper needle 31 on the PCB module 3 and fix it to the gun body shell 1; then lock the gun head 9 and the gun body shell 1 with four screws; then install the light guide column structure 11 on the gun body shell 1; then install the mechanical lock structure 10, and lock the support frame 1001 of the mechanical lock structure 10; finally install the decorative cover 12, the decorative cover 12 is snapped with the gun body shell 1 through the buckle, and a "click" sound is heard, indicating that it is installed in place. Among them, the detachable connection methods between variable modules and between variable modules and fixed modules include but are not limited to snap connection, threaded connection, and slot connection; the decorative cover 12 can cover the light guide column structure 11 and the screws connecting and covering the gun body shell 1 and the gun head 9.
