[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] This utility model provides a vehicle charger control box, such as Figure 1 , 2 As shown, the control box includes an outer shell and functional components disposed inside the outer shell. The outer shell is composed of a cylindrical shell and two side covers 3. The shell includes an upper cover 1 and a lower cover 2.

[0028] The upper cover 1 and the lower cover 2 enclose and interlock to form a cylindrical shell. Both ends of the shell have positioning grooves and first through holes. The positioning grooves are located below the ends of the shell, and their axes are parallel to the shell's axis. The bottom of the shell has a fixing hole, whose axis is perpendicular to the positioning groove axis and communicates with it. The side cover 3 has a positioning piece 4 corresponding to the positioning groove and a second through hole corresponding to the first through hole. The positioning piece 4 is embedded in the positioning groove, and a fastener passes through the fixing hole to secure the positioning piece 4 to the positioning groove, thus fixing the side cover 3 to the shell. In this embodiment, the fastener is a screw. The positioning piece has a through hole; after the positioning piece 4 is embedded in the positioning groove, the through hole corresponds to the fixing hole. The screw passes through the fixing hole and the through hole and is threaded into both.

[0029] The first and second wire-passing holes, which are positioned correspondingly, are used for wiring functional components. In this embodiment, the first wire-passing hole is located on the central axis of the cylindrical structure and protrudes outward from the end face of the cylindrical structure, while the corresponding second wire-passing hole protrudes outward from the end face of the side cover 3. Specifically, the end of the housing is provided as a frustum-shaped structure, and the protruding end of the frustum-shaped structure is provided as the first wire-passing hole; the side cover 3 is provided as a matching frustum-shaped structure and covers the end of the housing.

[0030] like Figure 3As shown, a rubber plug 7 is also provided, and the rubber plug 7 is the same color as the side cover 3, the upper cover 1, and the lower cover 2. In this embodiment, the through hole is located at the end of the positioning piece 4. After the positioning piece 4 is embedded in the positioning groove, the screw passes through the fixing hole and the through hole in sequence from the bottom periphery of the shell and is tightened. The rubber plug 7 is then inserted into the fixing hole to cover the screw, so that the appearance of the outer shell remains consistent.

[0031] The side cover 3 is also provided with a positioning pin 5. Both ends of the housing have grooves corresponding to the positions of the positioning pin 5, and the positioning pin 5 is interference-fitted with the grooves. Furthermore, the positioning pin 5 has a recess, and the groove has a protrusion that engages with the recess of the positioning pin 5. When the positioning piece 4 of the side cover 3 is inserted into the positioning groove, the positioning pin 5 is inserted into the groove and interference-fitted with it, and the recess of the positioning pin 5 simultaneously engages with the protrusion within the groove. For example... Figure 4 As shown, to further ensure sturdiness, the side cover 3 is also provided with a buckle 6, and both ends of the housing are provided with a groove that cooperates with the buckle 6.

[0032] In this embodiment, each side cover 3 has two positioning pieces 4 at its lower part, and positioning grooves are correspondingly provided at the end of the lower cover 2; each side cover 3 has two positioning pins 5 at its upper part, and buckles 6 are provided between the positioning pins 5, with grooves and slots correspondingly provided at the end of the upper cover 1. The buckles 6 are hook-shaped cantilever buckles, with the front end bent back to form a hook-shaped structure.

[0033] In practice, the upper positioning pin 5 of the side cover 3 is inserted into the groove of the upper cover 1, the buckle 6 engages with the corresponding slot of the upper cover 1, the lower positioning piece 4 of the side cover 3 is inserted into the corresponding positioning slot of the lower cover 2, and then the screw is passed through the fixing hole to fix the side cover 3 while the upper cover 1 and the lower cover 2 are engaged.

[0034] This utility model also provides an electric vehicle charging device, including the vehicle-mounted charging control box described above.

[0035] like Figure 1 As shown by the middle arrow, most existing products use screws at the four corners of the end cover to fix the end cover and the upper and lower covers, or use rubber plugs to block the screw holes; however, the screw positions are still visible on the end face. The car charger control box provided by this utility model uses an internal design structure to drive screws upwards from the bottom of the housing (lower cover 2) to fix the side cover 3 to the upper cover 1 and lower cover 2. When the car charger control box is in use, the bottom of the housing (the surface where the fixing holes of the lower cover 2 are located) is in contact with the plane below (such as the ground or tabletop), thereby completely covering the fixing holes and rubber plugs 7, so that no trace of the screws is visible from the outside of the product.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
