Detailed implementation manner

[0018] To enable those skilled in the art to more clearly understand the technical solution of the present application, the present utility model will be further described below with reference to the accompanying drawings.

[0019] As Figures 1-3 In the illustrated embodiment, a lithium battery forklift charger includes a main box 10 and components disposed within the main box 10. The main box 10 includes a first box body 11 and a second box body 12 that are cooperatively connected, and a protective plate 13 disposed on both sides of the first box body 11 and the second box body 12 and simultaneously covering the corresponding same sides of the first box body 11 and the second box body 12; the first box body 11 is a square structure, and a mounting rack 20 for mounting components is disposed therein; the second box body 12 is a trapezoidal structure, and the two side walls of the second box body 12 are empty box bodies, and the protective plate 13 is detachably covered on the empty box bodies and the side walls of the first box body 11.

[0020] Specifically, the front side of the first box body 11 is integrally penetrated with the rear side of the second box body 12. The first box body 11 includes a first top plate 111, a first bottom plate 112, a first side plate 113, and a rear plate 114. The second box body 12 includes a second top plate 121, a second bottom plate 122, a side frame 123, and a front plate 124. The width and height of the front plate 124 are both smaller than those of the rear plate 114; the second top plate 121 is an inclined trapezoidal plate, the top wall is fixedly connected to the front end face of the first top plate 111, the side wall is fixedly connected to the top end face of the protective plate 13, and the bottom wall is fixedly connected to the top end face of the front plate 124; the second bottom plate 122 and the first bottom plate 112 are integrally provided. A touch screen 30 is disposed in the middle of the second top plate 121. A start button and a stop button are disposed on one side of the touch screen 30, and an emergency stop button is disposed on the other side; a charging indicator light 40 is disposed on the front plate 124.

[0021] It can be understood that by designing the second box body 12, the space inside the entire main box 10 is increased, which is beneficial to the arrangement of components; through the detachably arranged protection plate 13, it is beneficial to assemble the components inside the main box 10, that is, by removing the protection plate 13, the components on the front side inside the main box 10 can be inspected and replaced. Since the two side walls of the second box body 12 are empty box bodies (i.e., side frames 123), it is convenient for the staff to directly enter the inside of the main box 10 to detect the components after removing the protection plate 13; and by removing the rear plate, the components on the rear side inside the main box can be inspected and replaced.

[0022] In this embodiment, the protection plate 13 includes a right trapezoidal plate 131 and a rectangular plate 132 which are integrally arranged. The right trapezoidal plate 131 is fastened with the side frame 123 by a rivet stud, and the rectangular plate 132 is fastened with the first side plate 113 by a rivet stud. An air inlet hole plate 50 is arranged on one side of the rectangular plate 132, and an air outlet hole plate 60, a gun wire hanger 70 and a waterproof connector 80 are arranged on the other side of the rectangular plate 132. It can be seen that through the design of the protection plate 13, the overall strength of the charger is increased, the protection level of the charger is improved, and at the same time, the aesthetics of the charger is increased.

[0023] A rear mounting plate 21 is arranged on the side of the mounting frame 20 close to the rear plate 114 to cooperate with the installation of components; a side mounting plate 22 is arranged on the side of the mounting frame 20 close to the first side plate 113 to cooperate with the installation of terminal blocks; an upper mounting plate 23 is arranged on the upper end surface of the mounting frame 20 to cooperate with the installation of components. It can be seen that the devices inside the main box 10 (including switch power supplies, control boards, DC contactors, copper bars, insulating columns, etc.) are all fixed on the mounting frame 20, making the arrangement of the devices inside the main box 10 simple and regular, without the situation of messy wire harnesses, and at the same time, the production operation is more simple and convenient.

[0024] The overall dimensions of the charger of this application are 620x530x300 mm in length, width and height, which meet the requirements of the charger being small, flexible and mobile. The overall dimension utilization rate is relatively high. When the charger is placed indoors, the space occupancy rate is relatively low, and it will not cause a space burden to the user.

[0025] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
