[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] The present utility model provides an electric vehicle controller that is convenient for disassembly and assembly, as Figures 1 to 6 shown.

[0030] Embodiment 1:

[0031] An electric vehicle controller that is convenient for disassembly and assembly includes a housing 1. The housing 1 is a rectangular frame body with openings at both ends, and end covers 2 are movably clamped at both ends of the housing 1. A clamping block 4 is also movably clamped inside the housing 1. The clamping block 4 can fixedly support electronic components. During installation, first install the electronic components on the clamping block 4, then insert the clamping block 4 into the inside of the housing 1, then connect the electronic components to the interfaces on the end cover 2 through cables, and finally install the end cover 2 on the housing 1.

[0032] The end cover 2 is stepped, and telescopic clamping blocks 4 are installed on the peripheral side walls of the convex part of the end cover 2. The clamping blocks 4 are slidably installed in a chute 9 opened on the end cover 2. One end of the chute 9 penetrates the side wall of the end cover 2, and the other end communicates with a cavity 10 opened inside the end cover 2. The inner end of the clamping block 4 extends into the interior of the cavity 10 and is hinged to a turntable 12 rotating inside the cavity 10 through a connecting rod 11. One end of the clamping block 4 close to the cavity 10 is the inner end, and the end far from the cavity 10 is the outer end. One end of the connecting rod 11 is hinged to the corresponding clamping block 4, and the other end is hinged to the turntable 12. The knob 6 is fixedly connected to the turntable 12, and the knob 6 penetrates the outer side surface of the end cover 2. By rotating the knob 6, the turntable 12 can be driven to rotate, so that the turntable 12 can pull or push the clamping block 4 to slide through the connecting rod 11, and then the expansion and contraction of the clamping block 4 can be controlled. When the clamping block 4 extends out, it can be clamped with the corresponding bayonet 5.

[0033] A rubber ring 13 is arranged between the knob 6 and the end cover 2, which can prevent the knob 6 from rotating without external force, so as to avoid the clamping block 4 disengaging from the bayonet 5, and then the end cover 2 falling off.

[0034] Slots 17 are opened on both end faces of the mounting plate 3. Clamping rods 19 are respectively connected to the two side walls of the slot 17 through arc-shaped elastic pieces 18. The concave surface of the elastic piece 18 faces away from the center position of the slot 17. The clamping rods 19 penetrate the side wall of the slot 17. Under the action of the self-elastic force of the elastic piece 18, the clamping rods 19 will retract into the interior of the mounting plate 3. A slot 20 adapted to the clamping rod 19 is opened on the side wall of the housing 1. A ejector rod 21 adapted to the elastic piece 18 is fixedly connected to the end cover 2. When the end cover 2 is installed on the housing 1, the ejector rod 21 will insert into the corresponding slot 17 and squeeze the elastic piece 18. When the elastic piece 18 is squeezed, the elastic piece 18 will produce corresponding elastic deformation. At this time, the clamping rod 19 will extend out of the interior of the mounting plate 3 and be clamped with the slot 20, so that the mounting plate 3 can be kept stable inside the housing 1.

[0035] Embodiment 2:

[0036] On the basis of Embodiment 1, in order to make the installation between the end cover 2 and the housing 1 closer and the sealing performance better, a sealing ring 7 is fixedly connected to the end face of the housing 1, and a sealing groove 8 adapted to the sealing ring 7 is opened on the end cover 2. When the end cover 2 is installed on the housing 1, the sealing ring 7 will be inserted into the sealing groove 8, so that the sealing performance between the end cover 2 and the housing 1 can be better.

[0037] Meanwhile, the outer end face of the clamping block 4 is set as an inclined surface that is higher on the inner side and lower on the outer side, and the inner side wall of the bayonet 5 is adapted to the inclined surface of the clamping block 4. The end of the clamping block 4 away from the cavity 10 is the outer end, the side of the clamping block 4 close to the center position of the housing 1 is the inner side, and the other side is the outer side. When the clamping block 4 is inserted into the side wall of the bayonet 5, the clamping block 4 will squeeze the side wall of the bayonet 5, so that the end cover 2 can be tightly pressed against the housing 1, further improving the sealing performance between the end cover 2 and the housing 1.

[0038] Embodiment 3:

[0039] On the basis of Embodiment 2, in order to prevent the knob 6 from rotating automatically without external force, a plurality of elastic rods 16 are installed inside the knob 6. Specifically, as follows:

[0040] The outer end face of the knob 6 is flush with the outer side face of the end cover 2 and is provided with an empty groove 14. The shape of the empty groove 14 can be hexagonal. The staff can rotate the knob 6 through an inner hexagon wrench. Inside the empty groove 14, there is a pressing plate 15. The peripheral side walls of the pressing plate 15 are fixedly connected with a plurality of elastic rods 16 distributed radially. The elastic rods 16 penetrate through the knob 6 and press against the rubber ring 13. Under the action of this pressing force, the knob 6 will remain stable. When it is necessary to rotate the knob 6, insert the corresponding inner hexagon wrench into the empty groove 14, and then press down the pressing plate 15 through the inner hexagon wrench. At this time, the elastic rod 16 generates elastic deformation against its own elasticity and no longer presses against the rubber ring 13. At this time, the knob 6 can be rotated smoothly.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
