Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a charging pile shell and a shaping mold and a shaping method thereof. Background Art

[0002] Since the first electric car was launched in the 19th century, it has been powered by rechargeable batteries. For an electric car, battery charging equipment is one of the indispensable subsystems. Its function is to convert the power of the power grid into the power of the battery on the electric car. In recent years, there are more and more electric cars in society, and the demand for charging pile equipment is also increasing.

[0003] As disclosed in the prior art invention patent with publication number CN106364340A and name of a charging pile shell, a charging pile shell includes a base and a shell, a baffle is fixed on the top of the shell, a GPS module and a wireless communication module are fixed on the upper part of the shell, a fan is fixed on the back of the shell, a charging interface is embedded in the front of the shell, the charging interface is provided with a waterproof cover, the charging interface is connected in series with an indicator light embedded in the shell, a photosensor is provided in the shell, and the photosensor is located directly behind the indicator light, the GPS module, the wireless communication module, the fan, and the photosensor are electrically connected to the controller arranged on the back of the shell respectively, and the wireless communication module is wirelessly connected to the management center server.

[0004] This structure can prevent rain from falling on the shell and sunlight from shining directly on the shell, but the manufacturing of the shell of this charging pile is cumbersome, which is not conducive to efficient production in the factory, and the actual shell occupies a large area and cannot be effectively applied to areas of different sizes. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a charging pile shell and a shaping mold and a shaping method thereof, which are used to solve the technical problems in the prior art that the charging pile shell in the background technology is cumbersome to manufacture and cannot be applied to areas of different spatial sizes.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A charging pile shell comprises an integrally formed rectangular shell body with rounded corners, the shell body comprising a shell bottom, a first shell wall installed at one end of the shell bottom, and a second shell wall installed at the other end of the shell bottom, the first shell wall and the second shell wall both extending upward at one end away from the shell bottom, and the end of the first shell wall away from the shell bottom is fixedly connected to the end of the second shell wall away from the shell bottom.

[0008] A shaping mold for a charging pile shell, used for shaping the above-mentioned charging pile shell, comprises a workbench, on which a first mounting plate and a second mounting plate perpendicular to the first mounting plate and fixedly connected to the first mounting plate are fixedly provided, the first mounting plate and the second mounting plate are respectively used to abut against two sides of the shell body, the workbench is also provided with a first shaping component that can be horizontally moved toward the direction of the first mounting plate, and the workbench is also provided with a second shaping component that can be horizontally moved toward the direction of the second mounting plate.

[0009] Working principle:

[0010] First, the parts of the shell bottom near the two ends are bent by a bending machine, and the end of one end of the shell bottom is bent 90° to form a first shell wall, and the other end of the shell bottom is bent 90° to form a second shell wall, and the end of the first shell wall away from the shell bottom is bent toward the direction between the first shell wall and the second shell wall by the bending machine. At this time, the bent end of the first shell wall is 90° with the first shell wall, and the end of the second shell wall away from the shell bottom is bent toward the direction between the first shell wall and the second shell wall by the bending machine. Because the molded shell body is a closed structure, the bending machine itself is limited when bending to the last corner. At this time, the angle between the bent end of the second shell wall and the second shell wall is greater than 100°;

[0011] Then, the bent shell bottom is placed on the shaping mold, the first shell wall is abutted against the first mounting plate, and the shell bottom is abutted against the second mounting plate. Then, by moving the first shaping component and the second shaping component, the first shaping component pushes the second shell wall, and the second shaping component pushes the end bending section of the second shell wall away from the shell bottom, and by continuously moving the first shaping component and the second shaping component horizontally, the end bending section of the second shell wall away from the shell bottom is pushed and bent until the bending section forms a 90° angle with the second shell wall. At this time, the end bending section of the second shell wall away from the shell bottom abuts against the end bending section of the first shell wall away from the shell bottom, and the folded edge is bent into a closed structure connected end to end.

[0012] After the bending is completed, the abutting portion of the bent section of the second shell wall away from the shell bottom end and the bent section of the first shell wall away from the shell bottom end are welded and fixed.

[0013] Beneficial effects obtained:

[0014] First, by setting the shell body as an integral molding, the shell body can be effectively made more concise, without redundant installation components, and the processing cost is low, the processing and molding are fast, and it is convenient for assembly line production in the factory.

[0015] Second, by providing the first mounting plate and the second mounting plate, the shell body can be effectively bent to an angle of 90° and fixed inside through the first mounting plate and the second mounting plate, and the two side walls of the shell body can be effectively supported when the shell body is reshaped.

[0016] Third, by setting up the first shaping component and the second shaping component, the other two side walls of the shell body can be effectively abutted by the first shaping component and the second shaping component, and by continuously squeezing the other two side walls, the four sides of the shell body can be shaped to 90°.
