[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] See also Figure 1-6 The utility model provides the following technical solution: a regenerative braking control device for an electric vehicle, comprising a housing 1, a heat dissipation copper plate 5, a main control module 6, a regenerative braking module 7, a heat dissipation fin 8 and a fixing mechanism 9.

[0039] With the help of the above technical solution, Figure 1 , Figure 2 and Figure 5 As shown, the right end of the shell 1 is fitted with a right dust filter 2, and the lower end of the right dust filter 2 is fixedly connected with a heat dissipation copper plate 5, the upper end of the heat dissipation copper plate 5 is fixedly installed with a main control module 6, and the regenerative braking module 7 is installed on the upper end of the main control module 6, and the main control module 6 and the regenerative braking module 7 are both existing mature technologies and are well known to those skilled in the art. The heat dissipation copper plate 5 and the heat dissipation fins 8 are fitted, and the heat dissipation fins 8 are arranged at equal intervals at the bottom of the shell 1. Through the arrangement of the heat dissipation copper plate 5 and the heat dissipation fins 8, it is convenient to dissipate the heat generated by the main control module 6 and the regenerative braking module 7 to the outside. Combined with the arrangement of the right dust filter 2 and the left dust filter 15, it can achieve the effect of ventilation and discharge the heat inside the shell 1 to the outside. At the same time, during ventilation and heat dissipation, it can prevent external dust from entering the shell 1 and adhering to the main control module 6 and the regenerative braking module 7;

[0040] like Figure 3 and Figure 4 As shown, when the main control module 6 and the regenerative braking module 7 fail during long-term use, through the setting of the fixing mechanism 9, the fixing mechanism 9 includes a fixing block 10 fixedly connected to the upper end of the right dust filter 2, a connecting rod 11 rotatably connected to the middle of the fixing block 10, a convex rod 12 for limiting, an auxiliary block 13 fixedly connected to the upper right end of the shell 1 and a limiting column 14 fixedly connected to the side of the auxiliary block 13. By rotating the connecting rod 11 to 90°, the first torsion spring at the connection between the connecting rod 11 and the fixing block 10 is elastically deformed, and the connecting rod 11 rotates in the limiting column 14. At the same time, the connecting rod 11 drives the convex rod 12 to rotate outward, so that the convex rod 12 is placed in the notch at the front end of the limiting column 14, thereby loosening the limit between the connecting rod 11 and the limiting column 14, and then pulling the right dust filter 2 to the right, the right dust filter 2 drives the stabilizing column 3 and the fixed long cylinder 4 to slide, thereby improving the stability of the right dust filter 2 during movement;

[0041] The right dust filter 2 drives the connecting rod 11 to be pulled out from the limiting column 14, and at the same time, the right dust filter 2 drives the heat dissipation copper plate 5 to move outward, so that the heat dissipation copper plate 5 drives the main control module 6 and the regenerative braking module 7 to be pulled out from the housing 1, thereby facilitating the disassembly, maintenance, inspection and cleaning of the main control module 6 and the regenerative braking module 7, which is very convenient to use. At the same time, the dust attached to the right dust filter 2 can also be cleaned. In addition, combined with Figure 6 As shown, the fixing pin 18 can also be flipped and rotated with the connecting plate 17, and the second torsion spring at the connection between the fixing pin 18 and the connecting plate 17 is elastically deformed. At this time, the fixing pin 18 is disengaged from the connecting column 16, thereby loosening the limit between the connecting column 16 and the connecting plate 17, and then the left dust filter 15 is pulled to the left, and the left dust filter 15 drives the connecting column 16 to disengage from the connecting plate 17, and the left dust filter 15 is moved away from the left side of the shell 1, thereby facilitating the disassembly and cleaning of the left dust filter 15 to prevent the left dust filter 15 from being clogged by dust during long-term use.

[0042] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
