The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0034] like Figures 1 to 7 As shown, a spliced ​​charger shell structure includes: a shell 1, the shell 1 has a accommodating cavity with open ends, the ends of the shell 1 partially protrude along the axial direction to form a convex portion 11, and the convex portion 11 has a card slot 12; a cover plate 2, which is provided with two, and the two cover plates 2 are respectively located at the two ends of the shell 1, and are used to close the accommodating cavity, and the cover plates 2 are provided with a card block 21 that can be inserted into the card slot 12; a positioning component 3, including a positioning shaft 31 and an elastic member 34, both ends of the shell 1 are provided with a slide groove 13, the positioning shaft 31 can be slidably arranged in the slide groove 13, the elastic member 34 is located in the slide groove 13, and the two ends of the elastic member 34 are respectively connected to the bottom of the slide groove 13 and the positioning shaft 31, and the cover plate 2 is provided with a positioning groove 22 for the positioning shaft 31 to be inserted and positioned.

[0035] Specifically, both left and right end surfaces of the shell 1 have a convex portion 11, and the convex portions 11 are located at the rear of the end surface of the shell 1. A card slot 12 is opened on the front side of the convex portion 11, and a card block 21 is provided on the rear side of the cover plate 2. The slide groove 13 is located at the front of the end surface of the shell 1. The positioning shaft 31 can slide left and right in the slide groove 13. The shell 1 and the cover plate 2 form a splicing structure through the cooperation of the card block 21, the card slot 12 and the positioning component 3. When assembling the housing 1, first insert the two cover plates 2 into the slots 12 of the convex parts 11 on the left and right sides of the housing 1 respectively. The cover plates 2 achieve the positioning effect by cooperating with the slots 12 through the block 21. Before the cover plates 2 are inserted into the slots 12, the cover plates 2 fit with the end faces of the housing 1, and the positioning shaft 31 is pressed to retract into the inside of the slide groove 13, and the elastic member 34 is deformed. When the cover plates 2 are fully inserted into the slots 12 to complete the positioning, the positioning shaft 31 is aligned with the positioning groove 22 of the cover plates 2, and the positioning shaft 31 is reset by the resilience of the elastic member 34, and is inserted into the positioning groove 22. The cover plate 2 is limited in its forward and backward movement and in its upward and downward movement to prevent the cover plate 2 from moving after being positioned. At the same time, the cooperation between the positioning shaft 31 and the positioning groove 22 also has a secondary positioning effect on the cover plate 2, so that the cover plate 2 and the end surface of the shell 1 are aligned and fit, which is more convenient for the assembly between the cover plate 2 and the shell 1, improves the assembly efficiency, and is easy to install. There is no need to repeatedly move the cover plate 2 for adjustment. The positioning can be completed by simply inserting the block 21 of the cover plate 2 into the slot 12 of the convex portion 11, which solves the problem of blocking the mounting hole when the cover plate 2 is combined with the shell 1.

[0036] Both ends of the housing 1 are provided with movable grooves 14 connected with the slide groove 13, and the positioning shaft 31 has an adjustment portion 32, which passes through the movable groove 14 and protrudes outward. The position of the positioning shaft 31 is slid by the adjustment portion 32, so as to adjust the insertion and removal of the positioning shaft 31 into and out of the slide groove 13. Specifically, the slide groove 13 is connected with the outside of the housing 1 through the movable groove 14, and the adjustment portion 32 of the positioning shaft 31 passes through the movable groove 14 and is exposed to the outside. When the cover plate 2 needs to be removed, the adjustment portion 32 is first slid to drive the positioning shaft 31 to move out of the positioning groove 22, and the cover plate 2 is no longer limited, and then the cover plate 2 is moved out to the front side.

[0037] In some embodiments of the present application, the outer edge of the positioning shaft 31 is chamfered to form a slope 311. Specifically, the four sides of the outer edge of the positioning shaft 31 are chamfered to form slopes 311 on all four sides, so that when the positioning shaft 31 is inserted into the positioning groove 22, it is guided by the slopes 311 on the four sides of the outer end of the positioning shaft 31, and can be accurately inserted into the positioning groove 22, preventing the positioning shaft 31 from abutting against the edge of the positioning groove 22, resulting in the phenomenon that the cover plate 2 cannot be limited.

[0038] In some embodiments of the present application, a plurality of ridges 33 are provided on one side of the adjusting portion 32 away from the positioning shaft 31, and the plurality of ridges 33 are evenly spaced. Specifically, five ridges 33 are provided on the outer end surface of the adjusting portion 32, which increases the friction force of the outer end surface of the adjusting portion 32, so that the user can avoid slipping when moving the positioning shaft 31 through the adjusting portion 32.

[0039] In some embodiments of the present application, both corners of the outer end of the block 21 are provided with rounded corners to form an arcuate surface 211. Both corners of the rear side of the block 21 are rounded to form an arcuate surface 211. When the block 21 of the cover plate 2 is inserted into the card slot 12, if the position of the cover plate 2 is offset, the arcuate surface 211 of the block 21 first contacts and cooperates with the notch of the card slot 12 to guide the block 21 left and right, and then adjust the position of the cover plate 2, so that the block 21 of the cover plate 2 can be more accurately inserted into the card slot 12 of the protrusion 11.

[0040] In some embodiments of the present application, there are two card slots 12, which are symmetrically distributed on one side of the convex portion 11, and card blocks 21 are provided at positions corresponding to the card slots 12 on the cover plate 2. Specifically, there are two card slots 12 provided on a single convex portion 11, and the two card slots 12 are respectively located on the left and right parts of the front side of the convex portion 11. Two card blocks 21 are provided on the cover plate 2, which correspond to the two card slots 12 of the convex portion 11 one by one. The cover plate 2 is inserted into the corresponding card slot 12 through the two card blocks 21, which further improves the positioning accuracy of the cover plate 2. At the same time, the cooperation between the card block 21 and the card slot 12 of the convex portion 11 also improves the connection firmness between the cover plate 2 and the housing 1.

[0041] In some embodiments of the present application, a first magnetic block 4 and a second magnetic block 5 with opposite polarities are also included. The first magnetic block 4 is arranged on the protrusion 11, and the second magnetic block 5 is arranged on the side of the cover plate 2 facing the protrusion 11. The first magnetic block 4 cooperates with the second magnetic block 5. Specifically, the first magnetic block 4 is arranged on the front side of the protrusion 11, and the second magnetic block 5 is arranged on the rear side of the cover plate 2. When the card block 21 of the cover plate 2 is inserted into the corresponding card slot 12, the first magnetic block 4 fits with the second magnetic block 5. The cover plate 2 and the shell 1 are attracted by the magnetic force of the first magnetic block 4 and the second magnetic block 5, so as to achieve the purpose of preliminary fixation, further prevent the cover plate 2 from being offset after positioning, and facilitate the assembly between the shell 1 and the cover plate 2, thereby improving the assembly efficiency.

[0042] In some embodiments of the present application, multiple threaded holes 15 are formed at both ends of the housing 1, through holes 23 are formed at positions corresponding to the threaded holes 15 on the cover plate 2, and bolts 6 are threadedly connected to the threaded holes 15 through the through holes 23 to fix the cover plate 2 to the housing 1. Specifically, six threaded holes 15 are formed on both side end faces of the housing 1, four of which are distributed on the end face of the housing 1, and two threaded holes 15 are distributed on the inner walls of the two slots 12. Through holes 23 are formed at positions corresponding to the six threaded holes 15 on the cover plate 2, and bolts 6 are formed in the through holes 23. The bolts 6 are threadedly connected to the threaded holes 15 through the through holes 23 to fix the cover plate 2 to the housing 1, and the assembly is completed.

[0043] In some embodiments of the present application, the ends of the threaded holes 15 are provided with a sink 16 along the edge, and the cover plate 2 is provided with a boss 24 that can be inserted into and matched with the sink 16, and the boss 24 is provided along the edge of the through hole 23. Specifically, when the block 21 of the cover plate 2 is fully inserted into the slot 12 of the convex portion 11, the boss 24 of the cover plate 2 is aligned with the sink 16 of the threaded hole 15 at the corresponding position, and the boss 24 is inserted into the sink 16 to match, and the threaded hole 15 is further aligned with the through hole 23 of the cover plate 2, ensuring a good positioning effect, facilitating the bolt 6 to pass through the through hole 23 and connect with the threaded hole 15, and improving assembly efficiency.

[0044] In some embodiments of the present application, the elastic member 34 is a compression spring. The elastic member 34 can also be configured as an elastic sheet.
