Specific embodiments

[0024] The features and performance of the present utility model are further described in detail below in conjunction with embodiments.

[0025] The scheme principle of the charging pile of the present utility model is as follows:

[0026] A charging pile includes a charging pile main body, and a gun insertion welding part for inserting a gun is welded on the housing of the charging pile main body. The gun insertion welding part of the charging pile specifically includes a welding part main body, and the welding part main body includes a gun insertion panel in a rectangular shape. Straight side walls extend from the longer sides of the gun insertion panel, an inclined short side wall extends from one of the shorter sides, and an inclined long side wall extends from the other shorter side. The planes where the edges of the two straight side walls on the side opposite to the gun insertion panel are located constitute a positioning welding plane.

[0027] One of the aforementioned inclined long side wall and inclined short side wall protrudes from the edge opposite to the gun insertion panel out of the positioning welding plane to form a positioning convex part. A positioning notch is provided at the edge of the opening corresponding to the gun insertion welding part on the housing of the charging pile main body, and the positioning notch is in positioning cooperation with the positioning convex part to realize the welding positioning of the gun insertion welding part of the charging pile on the housing of the charging pile main body.

[0028] When the charging gun welding part of the above charging pile is welded, it is easy to achieve positioning relative to the shell of the charging pile main body, and after welding is completed, the welding position of the charging gun welding part of the charging pile on the shell of the charging pile main body can be well maintained at the predetermined position. In this way, the consistency of the processed charging pile main body is better; at the same time, it is also convenient for welding operation, so the processing efficiency is higher.

[0029] Embodiment of the charging pile of the present utility model:

[0030] A charging pile includes a charging pile main body. The structure of the charging pile main body is that of an existing charging pile, which can be referred to Figures 3 - 5 As shown, a charging gun welding part 2 for inserting a gun is welded on the shell 1 of the charging pile main body.

[0031] The charging gun welding part 2 can be referred to Figure 6 、 Figure 7 As shown, it includes a welding part main body, and the welding part main body specifically includes a gun insertion panel 3 in a rectangular shape. A gun insertion hole 4 for inserting a gun and an installation hole 5 for installing related accessories are provided on the gun insertion panel 3. Straight side walls 6 extend from the longer sides of the gun insertion panel 3, an inclined short side wall 7 extends from one of the shorter sides, and an inclined long side wall 8 extends from the other shorter side. The planes where the edges of the two straight side walls 6 on the side facing away from the gun insertion panel 3 are located form a positioning welding plane 9. During welding, this positioning welding plane 9 is directly attached to the shell 1 of the charging pile main body.

[0032] It can be referred to Figure 6 As shown, the edge of one of the inclined long side wall 8 and the inclined short side wall 7 facing away from the gun insertion panel 3 protrudes from the positioning welding plane 9, so that a positioning convex part 10 of the charging gun welding part 2 can be formed. An opening for inserting a gun is provided at the welding position of the charging pile main body corresponding to the charging gun welding part 2, and a positioning notch is provided at the edge of the opening corresponding to the aforementioned positioning convex part 10. During welding, the positioning convex part 10 is first positioned and inserted into the positioning notch to achieve the positioning of the charging gun welding part 2 on the shell 1 of the charging pile main body. The edge of the other of the inclined long side wall 8 and the inclined short side wall 7 facing away from the gun insertion panel 3 is located within the positioning welding plane 9 to ensure that the charging gun welding part and the shell 1 of the charging pile main body can be fully welded.

[0033] The key point of this embodiment is that the edge of the other of the inclined long side wall 8 and the inclined short side wall 7 facing away from the gun insertion panel 3 is bent outward along the positioning welding plane 9 to form a bent edge 11. In this way, the contact area and welding area between the charging gun welding part 2 and the shell 1 of the charging pile main body can be increased, and further, the charging gun welding part 2 and the shell 1 of the charging pile main body have higher welding strength.

[0034] Specifically, the edge of the inclined long side wall 8 facing away from the gun insertion panel 3 can protrude from the positioning welding plane 9, and the edge of the inclined short side wall 7 facing away from the gun insertion panel 3 can be bent to form a bent edge 11 along the positioning welding plane 9. Alternatively, the edge of the inclined short side wall 7 facing away from the gun insertion panel 3 can protrude from the positioning welding plane 9, and the edge of the inclined long side wall 8 facing away from the gun insertion panel 3 can be bent to form a bent edge 11 along the positioning welding plane 9. The positioning convex portion 10 is preferably provided on the lower one of the inclined long side wall 8 and the inclined short side wall 7. After welding is completed, due to the positioning cooperation between the positioning convex portion 10 and the positioning notch, the cooperation between the positioning notch and the positioning convex portion 10 can share the weight of the gun. The above can reduce the load on the weld between the charging gun weldment 2 of the charging pile and the housing 1 of the charging pile main body, thereby reducing the welding process requirements and improving the service life of the welding structure at this place. In this embodiment, the inclined long side wall 8 is located below, the inclined short side wall 7 is located above, and the positioning convex portion 10 is provided on the inclined long side wall 8. In other embodiments, the inclined long side wall 8 can also be located above, the inclined short side wall 7 can be located below, and the positioning convex portion 10 can be provided on the inclined short side wall 7.

[0035] for reference Figure 7 As shown, the foregoing positioning convex portion 10 and bent edge 11 do not exceed the straight side wall 6 in the width direction of the gun insertion panel 3. Such a design is convenient for processing. Whether the charging gun weldment 2 of the charging pile is processed by the method of bending and welding sheet metal or by the method of integral stamping, the above structure can avoid additional cutting of the sheet material, saving materials and improving processing efficiency. Of course, the foregoing positioning convex portion 10 and bent edge 11 can also exceed the straight side wall 6 in the width direction of the gun insertion panel 3.

[0036] The welded part body is a stretched body integrally processed by stretching and stamping, that is, the aforementioned gun insertion panel 3, straight side wall 6, inclined short side wall 7, and inclined long side wall 8 are integrally processed by stretching and stamping. The existing charging pile gun insertion welded part 2 is formed by bending and then welding, that is, the sheet material is first cut into a predetermined shape, and then the four side edges of the gun insertion panel 3 are bent respectively to form the straight side wall 6, inclined short side wall 7, and inclined long side wall 8. After bending, the straight side wall 6 is connected to the inclined short side wall 7 and the straight side wall 6 is connected to the inclined long side wall 8 by welding respectively. During the process of repeatedly inserting the gun, the weld seams of the above structure are prone to cracking due to fatigue, thereby causing the structure of the charging pile gun insertion welded part 2 to fail. At the same time, when bending and forming, since the angles between the inclined long side wall 8 and the gun insertion panel 3, and between the gun insertion panel 3 and the inclined short side wall 7 are generally not right angles; therefore, after bending, the edges of the inclined short side wall 7 and the straight side wall 6 facing away from the gun insertion panel 3 are difficult to be in the same plane. This easily affects the welding quality, and further processing and trimming are required to make the edges of the inclined short side wall 7 and the straight side wall 6 facing away from the gun insertion panel 3 be in the same plane. Therefore, it is not easy to ensure the strength of the charging pile gun insertion welded part 2 by the method of bending and then welding, and at the same time, the processing cost is high. By integrally processing and forming the above structure by stretching and stamping, on the one hand, the strength of the charging pile gun insertion welded part 2 can be improved, and on the other hand, the straight side wall 6, inclined short side wall 7, and inclined long side wall 8 can be integrally cut off. This can effectively ensure the length and inclined angle of the inclined long side wall 8, thereby ensuring that the positioning convex part 10 has good position accuracy; at the same time, it can also ensure that the edges of the straight side wall 6 and the inclined short side wall 7 facing away from the gun insertion panel 3 are in the same plane, effectively simplifying the processing technology.

[0039] The above is only the preferred embodiment of the present utility model, and it is not intended to limit the present utility model. The patent protection scope of the present utility model is subject to the claims. Any equivalent structural changes made by using the description and drawings of the present utility model should be included in the protection scope of the present utility model by the same token.
