In addition, the second slide rail 51 and the second slider 52 can also effectively limit the movement of the PCB module 3 to prevent the PCB assembly from shaking and being damaged.

[0045] In one example, the first slide rail 41 is set on the tray structure 2, and the first slider 42 is set on the inner wall of the gun body shell 1.

[0046] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 3 The charging and discharging gun also includes a positioning structure 6, which is set between the PCB module 3 and the tray structure 2 for positioning the PCB module 3.

[0047] As an example, the charging and discharging gun also includes a positioning structure 6.

At the same time, it can also position the PCB module 3 to prevent the PCB module 3 from moving, making the installation of the PCB module 3 more stable and reliable, and preventing the PCB module 3 from being damaged by collision.

[0048] In one embodiment, reference is made to Figure 1 and Figure 2 The positioning structure 6 includes a positioning post 61 and a positioning hole 62; the positioning post 61 is set on the PCB module 3 or the tray structure 2, the positioning hole 62 is set on the tray structure 2 or the PCB module 3, and the positioning post 61 is inserted into the positioning hole 62.

[0049] As an example, the positioning structure 6 includes a positioning post 61 and a positioning hole 62. During installation, the positioning post 61 is placed on the PCB module 3, and the positioning hole 62 is placed on the tray structure 2. The positioning post 61 is inserted into the positioning hole 62, which can provide guidance for the installation of the PCB module 3 and improve the assembly efficiency of the PCB module 3. At the same time, it can position the PCB module 3 to prevent the PCB module 3 from moving, making the installation of the PCB module 3 more stable and reliable, and preventing the PCB module 3 from being damaged by collision.

[0050] In one example, the positioning post 61 is set on the tray structure 2, the positioning hole 62 is set on the PCB module 3, and the positioning post 61 is inserted into the positioning hole 62, which can also achieve the above function.

[0051] In one embodiment, reference is made to Figure 2 The tray structure 2 includes a main board 22 arranged in a horizontal direction, a support plate 23 extending vertically from the first end of the main board 22, and two reinforcing plates 24 extending horizontally from the opposite sides of the support plate 23; there is a gap between each reinforcing plate 24 and the main board 22; the PCB module 3 is mounted on the main board 22, and the copper pins 31 of the PCB module 3 are snapped into the snap-fit ​​grooves 21 of the support plate 23.

[0052] As an example, the pallet structure 2 includes a main board 22, a support plate 23, and two reinforcing plates 24. The main board 22 is arranged in a horizontal direction. The support plate 23 is a component that extends vertically from the first end of the main board 22. The two reinforcing plates 24 are components that extend horizontally from opposite sides of the support plate 23. There is a gap between each reinforcing plate 24 and the main board 22. In this way, the support structure formed by the main board 22, the support plate 23, and the two reinforcing plates 24 can reduce the weight of the pallet structure 2 while ensuring the support strength, which is beneficial to lightweight design. During installation, the PCB module 3 is mounted on the motherboard 22, and the copper pins 31 of the PCB module 3 are snapped into the snap-fit ​​grooves 21 of the support plate 23. The first slide rail 41 is set on the inner wall of the gun body shell 1, and the first slider 42 is set on the motherboard 22. The first slider 42 is movably mounted in the first slide rail 41. This provides guidance for the installation of the tray structure 2, allowing the tray structure 2 to be smoothly installed into the gun body shell 1, thereby facilitating the installation and disassembly of the PCB assembly and improving the assembly efficiency of the charging and discharging gun. In addition, the cooperation of the first slide rail 41 and the first slider 42 can also effectively limit the tray structure 2, preventing the PCB assembly from shaking and being damaged. The support plate 23 is provided with through holes for placing other wire harnesses.

[0053] In one embodiment, reference is made to Figure 2 and Figure 3 The charging and discharging gun also includes a charging cable 7, a charging cable fixing and anti-detachment structure 8, and a gun head 9. The charging cable 7 passes through the first end of the gun body shell 1, and the terminal of the charging cable 7 is connected to the input terminal of the PCB module 3. The charging cable fixing and anti-detachment structure 8 is fitted on the charging cable 7 and fixed to the first end of the gun body shell 1 to achieve anti-detachment fixing of the charging cable 7. The gun head 9 is detachably installed on the second end of the gun body shell 1, and the copper pins 31 of the PCB module 3 pass through the gun head 9.

[0054] As an example, the charging and discharging gun also includes a charging cable 7, a charging cable fixing and anti-detachment structure 8, and a charging head 9. During installation, the charging cable 7 is inserted from the first end of the gun body shell 1, and the terminal of the charging cable 7 is connected to the input terminal block of the PCB module 3. The charging cable fixing and anti-detachment structure 8 is fitted onto the charging cable 7 and fixed to the first end of the gun body shell 1. In this way, the charging cable 7 can be fixed to prevent it from detaching, thus preventing the charging cable 7 from becoming loose and affecting its connection with the PCB module 3, and ensuring the functionality of the charging and discharging gun. The gun head 9 is detachably installed at the second end of the gun body shell 1, and the copper pins 31 of the PCB module 3 pass through the gun head 9. Specifically, the gun head 9 has a locking protrusion or a locking groove, and the inner wall of the gun body shell 1 has a locking groove or a locking protrusion. The locking protrusion engages in the locking groove to achieve pre-installation of the gun head 9. Then, fasteners (such as bolts or screws) are inserted into the gun body shell 1 and the gun head 9 to lock and fix the gun head 9. This facilitates the installation and removal of the gun head 9, thereby improving the assembly efficiency of the charging and discharging gun. The charging and discharging gun also includes a signal copper pin fixing component 13; the signal copper pin fixing component 13 is installed in the recess on the gun head 9 and is used to fix the CC signal copper pin and the CP signal copper pin.

[0055] In one embodiment, reference is made to Figure 2 and Figure 3 The gun wire fixing and anti-dislodgement structure 8 includes a spiral locking ring 81, a fixing clip 82, and a locking member 83; the spiral locking ring 81 is installed inside the first end of the gun body shell 1 and is fitted onto the gun wire 7; the locking member 83 is installed on the fixing clip 82 to clamp the gun wire 7, and the fixing clip 82 is fixed at the port of the first end of the gun body shell 1.

[0056] As an example, the anti-detachment structure 8 for the charging cable includes a spiral locking ring 81, a fixing clip 82, and a locking element 83. During installation, the spiral locking ring 81 is first installed inside the first end of the gun housing 1 and then fitted onto the charging cable 7, thus locking the charging cable 7 inside the gun housing 1 for the first time to prevent it from falling off. Then, the locking element 83 is installed on the fixing clip 82 to clamp the charging cable 7. Finally, the fixing clip 82 is fixed to the port at the first end of the gun housing 1, thus locking the charging cable 7 inside the gun housing 1 for the second time to prevent it from falling off. In this example, the anti-detachment structure 8 can double-lock the charging cable 7, achieving anti-detachment fixation and preventing the charging cable 7 from loosening and affecting its connection with the PCB module 3, ensuring the functionality of the charging gun. The spiral locking ring 81 and the fixing clip 82 are fixed and limited by a screw on the fixing clip 82; the diameters of the spiral locking ring 81 and the charging cable 7 are adaptively adjustable.

[0057] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 3The gun body shell 1 adopts an integral molding structure. The gun body shell 1 includes a main body 101, a grip part 102 extending from a first end of the main body 101, and a mounting part 103 extending from a second end of the main body 101.

The accommodating space is used to install the mechanical lock structure 10. The inner wall of the mounting part 103 is provided with a first guide structure 4, and / or, the inner wall of the mounting part 103 is provided with a second guide structure 5.

[0058] As an example, the gun body shell 1 adopts a one-piece molded structure with a cylindrical shape, requiring no assembly and providing better waterproofing. Specifically, the gun body shell 1 includes a main body 101, a grip 102, and a mounting part 103. The grip 102 is a component extending from the first end of the main body 101, and the mounting part 103 is a component extending from the second end of the main body 101. The included angle between the main body 101 and the grip 102 is 9-11°, preferably 10°, which is more in line with ergonomics. An accommodating space is formed between the mounting part 103 and an inner wall of the main body 101. The accommodating space is used to install a mechanical lock structure 10. The mechanical lock structure 10 can mechanically lock the charging interface connected to the charging gun, ensuring the connectivity between the charging interface and the charging gun.

[0059] In this example, a first guide structure 4 can be provided on the inner wall of the mounting part 103. The tray structure 2 is installed in the mounting part 103 through the first guide structure 4. This provides guidance for the installation of the tray structure 2, allowing it to be smoothly installed into the mounting part 103, thereby facilitating the installation and disassembly of the PCB assembly and improving the assembly efficiency of the charging and discharging gun. Alternatively, a second guide structure 5 can be provided on the inner wall of the mounting part 103. This provides guidance for the installation of the PCB module 3, allowing it to be smoothly installed into the mounting part 103, thereby facilitating the installation and disassembly of the PCB assembly and improving the assembly efficiency of the charging and discharging gun. Alternatively, a first guide structure 4 and a second guide structure 5 can be provided on the inner wall of the mounting part 103. The tray structure 2 is installed in the mounting part 103 through the first guide structure 4, while the PCB module 3 is installed in the mounting part 103 through the second guide structure 5. Both the first guide structure 4 and the second guide structure 5 provide convenience for the installation and disassembly of the PCB assembly, thereby improving the assembly efficiency of the charging and discharging gun. The material of the gun body shell 1 includes, but is not limited to, plastic, metal or composite materials.

[0060] In one embodiment, reference is made to Figure 1 and Figure 2The main body 101 is provided with a pressing groove 104 communicating with the accommodating space; the charging and discharging gun also includes a mechanical lock structure 10, which includes a support frame 1001, a locking tongue 1002, an elastic element 1003, and a pressing button 1004; the support frame 1001 is installed in the accommodating space, the middle part of the locking tongue 1002 is rotatably installed on the support frame 1001, the first end of the locking tongue 1002 extends to the position of the pressing groove 104, and the second end of the locking tongue 1002 extends outside the accommodating space, for locking the charging interface connected to the charging and discharging gun; the elastic element 1003 is provided at the first end of the locking tongue 1002 to keep the locking tongue 1002 in a locked state; the pressing button 1004 is installed in the pressing groove 104, and pressing the pressing button 1004 keeps the locking tongue 1002 in an unlocked state.

[0061] As an example, the charging gun also includes a mechanical lock structure 10, which can mechanically lock the charging interface connected to the charging gun, ensuring the connectivity between the charging interface and the charging gun. The mechanical lock structure 10 includes a support frame 1001, a locking tongue 1002, an elastic element 1003, and a pressing button 1004. During installation, the support frame 1001 is installed within the accommodating space. Specifically, the mounting part 103 is provided with a mounting rail. The support frame 1001 has a U-shaped structure and is movably mounted on the mounting rail, providing guidance and limiting for its installation, facilitating its installation and disassembly. Simultaneously, the support frame 1001 and the mounting rail cooperate to form a movable space, in which the locking tongue 1002 is installed. The middle part of the locking tongue 1002 is rotatably mounted on the support frame 1001. The main body 101 is provided with a pressing groove 104 communicating with the accommodating space. The first end of the locking tongue 1002 extends to the location of the pressing groove 104, and the second end of the locking tongue 1002 extends outside the accommodating space. This configuration places the elastic element 1003 at the first end of the locking tongue 1002. Utilizing the elasticity of the elastic element 1003, the locking tongue 1002 rotates counterclockwise, thus locking the locking tongue 1002 and ensuring that the second end of the locking tongue 1002 can lock the charging interface connected to the charging gun. The pressing button 1004 is installed in the pressing groove 104. Pressing the pressing button 1004 compresses the elastic element 1003, causing the locking tongue 1002 to rotate clockwise, thus unlocking the locking tongue 1002 and allowing the user to separate the charging interface from the charging gun.

[0064] Currently, different customers have varying needs regarding the appearance and functionality of charge / discharge guns. Traditional charge / discharge guns typically feature a monolithic casing design. When meeting diverse customer requirements, the entire casing often needs to be redesigned, resulting in high R&D costs and long development cycles. Furthermore, the lack of interoperability between different designs and the inability to share components further increases production costs. Therefore, developing a charge / discharge gun that can be flexibly customized and reduces costs is of significant practical importance.

[0065] In this example, the tray structure 2, the gun wire fixing and anti-detachment structure 8, the gun head 9, and the mechanical lock structure 10 are fixed modular components, ensuring 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 variable modular components, which can be quickly customized in design and production according to different customer needs. Specifically, the 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; and the gun body shell 1 can be customized with different sizes, shapes, and materials according to customer needs. By combining and assembling variable and fixed modules, new charging and discharging gun designs can be quickly customized to meet diverse needs. This achieves flexible customization design, with a reasonable structural design concept, strong practicality and promotional value, reducing production costs and R&D cycles. It can be widely used in the design of various charging pile products, especially suitable for scenarios that require adaptation to multiple technical specifications and appearance requirements.

[0066] The assembly steps for the variable and non-variable modules are as follows: First, thread the gun wire 7 through the inside of the gun housing 1 and snap the connector of the gun wire 7 onto the input terminal block of the PCB module 3; second, tighten the gun wire fixing anti-detachment structure 8 according to the length of the gun wire 7; then install the PCB module 3 onto the tray structure 2, and then insert the tray structure 2 and the PCB module 3 into the gun housing 1 along the guide structure inside the gun housing 1. Installation and fixation can be achieved without the use of fasteners (such as screws); then insert the gun head 9 into the copper pin 31 on the PCB module 3 and fix it into the gun housing 1; then tighten the gun head 9 and the gun housing 1 with four screws; then install the light guide post structure 11 on the gun housing 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, which is snapped into the gun housing 1 by a buckle. A "click" sound indicates that the installation is in place.
