Description

Technical Field

[0001] This utility model relates to the field of charging guns that are easy to assemble, specifically a charging gun that is easy to assemble. Background Technology

[0002] The charging gun is a key component of a new energy charging system. Currently, charging guns on the market generally suffer from complex structures and low efficiency during assembly. Traditional charging guns typically employ multi-layered circuit designs and adhesive fixing methods, which not only increase assembly steps but also extend the production cycle due to glue curing time. Furthermore, the installation of internal electrical modules largely relies on screw fixing, requiring repeated adjustments during assembly, leading to cumbersome operations. This design not only reduces production efficiency but also increases the difficulty of later maintenance; if a module malfunctions, it often requires disassembling the entire charging gun, resulting in high repair costs.

[0003] For example, Chinese patent CN106887751A discloses a charging gun that optimizes waterproof performance through a magnetic switch and non-contact control, but its structural design still lacks the advantage of easy assembly. The locking components and circuit modules of this patent are installed separately, requiring precise alignment of the magnetic elements and magnetic switch, making the assembly process complex and with a low tolerance for error. Furthermore, its waterproof and breathable components are assembled from multiple parts (such as the upper cover, lower cover, and waterproof ring), further increasing the assembly difficulty.

[0004] Therefore, it is necessary to provide a charging gun that is easy to assemble. Utility Model Content

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, an embodiment of this application provides a charging gun that is easy to assemble, including a housing body 1, a gun head 2 connected to one end of the housing body 1, a cable assembly 8 connected to the other end of the housing body 1, and a plurality of electrical modules (not shown in the figure) electrically connected to the cable assembly 8 and the gun head 2. It also includes a shelf 3 for placing the electrical modules. The inner wall of the housing body 1 is provided with a guide seat 4 and limiting protrusions 5 located on both sides of the guide seat 4. The guide seat 4 is provided with a sliding groove 400. The shelf 3 includes a base plate 32, a slide bar 31 disposed at the lower end of the base plate 32 and cooperating with the sliding groove 400, a vertical plate 33 disposed on one side of the base plate 32, and abutment plates 34 disposed on both sides of the vertical plate 33. The upper surface of the base plate 32 is provided with positioning posts 35 for positioning the electrical modules.

[0024] During actual assembly, the cable assembly 8 is first assembled with the housing, and the electrical module is fixed to the base plate 32 with screws. Then, the slide block 3 is assembled with the gun head 2, and the gun head 2 is assembled with the cable assembly 8 (the pin header and terminal are plugged in to achieve conductivity). Then, the slide block and the gun head 2 are assembled on the housing body 1, so that the slide bar 31 and the slide groove 400 slide and engage, and the vertical plate 33 abuts against the limiting protrusion 5. After the gun head 2 and the housing body 1 are connected, the gun head 2 and the housing body 1 are locked with screws.

[0025] In the above design, the structural design and specific implementation of the storage slide 3 facilitate the installation of various electrical modules, and can work with the limiting protrusion 5 and the guide seat 4 to achieve the stability of the storage slide 3 after assembly, thereby improving assembly efficiency.

[0026] Specifically: such as Figure 4 As shown, the vertical plate 33 is provided with positioning holes, and the gun head 2 is provided with positioning shafts 9 that correspond one-to-one with the positioning holes.

[0027] During actual assembly, the vertical plate 33 is fixed to the gun head 2 by extending the positioning shaft 9 into the positioning hole.

[0028] In the above design, the structural design of the vertical plate 33 and the gun head 2, as well as the specific implementation method, facilitate the assembly of the gun head 2 and the storage slide 3, and improve the assembly accuracy.

[0029] Specifically: such as Figure 1 and Figure 2 As shown, the shell body 1 is also provided with a hook assembly 6. The hook assembly 6 includes an elastic end cap 61, a guide plate 62 on the shell body 1, and a hook 63 hinged to the guide plate 62. The shell body 1 is provided with a mounting cavity 100 and a mounting hole 101 for installing the hook 63. The mounting cavity 100 extends axially along the hook 63, and the mounting hole 101 communicates with the mounting cavity 100. Figure 5 As shown, the elastic end cap 61 includes a cap body 611, a positioning pin 612 disposed on the lower end face of the cap body 611, and buckles 613 disposed on both sides of the cap body 611. The hook 63 is provided with a first hole that cooperates with the positioning pin 612. The outer side of the buckle 613 is provided with a step 130 that abuts against the side wall of the through hole. The inner side of the buckle 613 is provided with a support part 131 for supporting one end of the hook 63.

[0030] During actual assembly, first hinge the guide plate 62 to the hook 63, then assemble the guide plate 62 to the shell body 1, and assemble the elastic end cap 61 to the mounting hole 101. Then, pass one end of the hook 63 through the mounting cavity 100 and insert it into the mounting hole 101, so that one end of the hook 63 is assembled with the support part 131, and the positioning pin 612 extends into the first hole. When it is necessary to attach the charging gun to an external charging pile during use, connect the hook 63 to the charging pile. When it is necessary to remove the charging gun, press the elastic end cap 61, so that one end of the hook 63 and the elastic end cap 61 are pressed down and the other end is raised, thus detaching the hook 63 from the charging pile.

[0031] In the above design, the structural design and specific implementation of the hook assembly 6 can effectively achieve the mounting and coordination with the external charging pile.

[0032] Specifically: such as Figure 6 As shown, the guide plate 62 includes a first plate 621 and a second plate 622 disposed on both sides of the first plate 621. The second plate 622 and the first plate 621 form a strip groove. The hooks 63 abut against the opposite side of the second plate 622 on both sides. The length of the second plate 622 is greater than the length of the first plate 621.

[0033] In actual use, hook 63 is hinged to plate 622 via a pin. The lower end face of hook 63 abuts against plate 621, and the two sides of hook 63 abut against the opposite side of plate 622. Plate 622 limits the two sides of hook 63, so that hook 63 will not deviate when rotating.

[0034] In the above design, the structural design and specific implementation of the guide plate 62 facilitate the connection of the hook 63, ensuring that the hook 63 will not deviate when rotating.

[0035] Specifically: such as Figure 1 and Figure 2 As shown, it also includes a protective sleeve 7. The shell body 1 is provided with an installation step 130 for installing the protective sleeve 7. One end of the protective sleeve 7 abuts against the gun head 2, and the other end of the protective sleeve 7 abuts against the installation step 130. The protective sleeve 7 and the shell body 1 are provided with a protective cavity that communicates with the installation cavity 100. The end of the hook 63 extends out of the protective cavity.

[0036] During actual assembly, after the protective sleeve 7 is assembled with the shell body 1, the hook 63 located in the mounting cavity 100 is partially inside the protective sleeve 7.

[0037] In the above design, the structural design and specific implementation of the protective sleeve 7 can effectively protect the hook 63.

[0038] Specifically: such as Figure 2 and Figure 4 As shown, the gun head 2 includes a gun body 21 and a limiting plate 22 disposed on the gun body 21. The limiting plate 22 is provided with a notch 23. The hook 63 extends out of the notch 23. The shell body 1 abuts against one side of the limiting plate 22. One end of the gun body 21 extends into the shell body 1 and is bolted to the shell body 1.

[0039] During actual assembly, the limiting plate 22 is abutted against the shell body 1, so that the gun body 21 on one side of the limiting plate 22 extends into the shell body 1. Then, the gun body 21 is connected to the shell body 1 by screws passing through the through hole of the shell body 1 and the screw hole of the gun body 21.

[0040] In the above design, the structure of the gun head 2 is designed to facilitate connection with the shell body 1.

[0041] Specifically: such as Figure 4As shown, the base plate 32 is provided with a plurality of strip holes 320.

[0042] In the above design, the weight of the storage slide 3 can be effectively reduced by setting the strip hole 320, thus saving raw material costs.

[0043] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
