[0022] First embodiment

[0023] Please refer to Figures 1 to 4 , wherein Figure 1 is a schematic structural diagram of the whole of the first embodiment, Figure 2 is a schematic exploded view of the whole of the first embodiment, Figure 3 is Figure 2 front orthographic view of the structure of, Figure 4 is Figure 1 partial enlarged view of the structure at position A of.

[0024] The present utility model provides an electric vehicle controller housing: including an upper housing 101, a lower housing 102 and two groups of limiting components. The limiting components include two insertion columns 103, a moving plate 104, a slider 105, a resisting spring 106, two pressing arc blocks 107, a semi-circular block 108 and a pull rod 109. Through the foregoing solution, the problem that a large number of bolts are required to fasten the upper housing 101 and the lower housing 102, which takes a relatively long time and a lot of manpower, is troublesome to operate and not convenient for subsequent disassembly, is solved.

[0025] For this specific embodiment, a heat dissipation window 112 is opened on the outer side of the lower housing 102. Each group of the limiting components is respectively connected to the upper housing 101 and the lower housing 102. The limiting components can be used to quickly connect the upper housing 101 and the lower housing 102. By providing the heat dissipation window 112 on the lower housing 102, heat dissipation conduction can be carried out on the controller, which is beneficial to the operation of the controller.

[0026] Among them, both of the two plug columns 103 are fixedly connected to the lower housing 102 and are both located above the lower housing 102. Both of the two plug columns 103 are also movably connected to the upper housing 101 and penetrate through the upper housing 101. Both of the two plug columns 103 have fixing holes 111. The upper housing 101 has sliding grooves 110. The slider 105 is movably connected to the upper housing 101 and is located in the sliding grooves 110. The abutting spring 106 is arranged in the sliding grooves 110 and is fixedly connected to the slider 105. The moving plate 104 is fixedly connected to the slider 105 and is located above the slider 105. Both of the two extrusion arc blocks 107 are fixedly connected to the moving plate 104 and are both located on the outer side wall of the moving plate 104. Both of the two extrusion arc blocks 107 are also respectively adapted to the corresponding fixing holes 111. When connecting the upper housing 101 and the lower housing 102, by inserting the plurality of plug columns 103 below the lower housing 102 towards the upper housing 101, the plurality of plug columns 103 all penetrate through the upper housing 101 and push the extrusion arc blocks 107 on the two moving plates 104. The moving plates 104 will move on the upper housing 101. At the same time, the slider 105 below the moving plates 104 squeezes the abutting spring 106 in the sliding grooves 110 of the upper housing 101. When the end face of the upper housing 101 is in contact with the end face of the lower housing 102, the acting force of the abutting spring 106 will push the slider 105 to reset. Each moving plate 104 drives the two extrusion arc blocks 107 into the fixing holes 111 of the corresponding plug columns 103, so that the upper housing 101 and the lower housing 102 are connected and fixed. When disassembling, by pulling the two moving plates 104, each moving plate 104 disengages the extrusion arc block 107 from the fixing hole 111 of the plug column 103, and then separates the upper housing 101 and the lower housing 102. Through the above method, it is realized that the upper housing 101 and the lower housing 102 can be quickly connected and fixed, the operation is simple, and it is convenient for subsequent disassembly.

[0027] Secondly, the semi-circular block 108 is fixedly connected to the plug column 103 and is located above the plug column 103. By arranging the semi-circular block 108 above the plug column 103, the semi-circular block 108 has an arc surface. The plug column 103 can conveniently penetrate through the upper housing 101 through the semi-circular block 108. In addition, the plug column 103 can facilitate the extrusion of the extrusion arc block 107 through the semi-circular block 108.

[0028] Meanwhile, the pull rod 109 is fixedly connected to the slider 105 and penetrates through the sliding groove 110. By providing the pull rod 109, the moving plate 104 can be moved by using the pull rod 109, which facilitates the separation of the extrusion arc block 107 from the insertion column 103.

[0029] When connecting the upper housing 101 and the lower housing 102, by inserting the plurality of insertion columns 103 below the lower housing 102 into the upper housing 101, the plurality of insertion columns 103 all penetrate through the upper housing 101. The semi-circular blocks 108 on each insertion column 103 will respectively push the extrusion arc blocks 107 on the two moving plates 104, and the moving plates 104 will move on the upper housing 101. At the same time, the slider 105 below the moving plate 104 will squeeze the abutting spring 106 in the sliding groove 110 of the upper housing 101. When the end face of the upper housing 101 is in contact with the end face of the lower housing 102, the acting force of the abutting spring 106 will push the slider 105 to reset. Each moving plate 104 drives the two extrusion arc blocks 107 into the fixing holes 111 of the corresponding insertion columns 103, so as to connect and fix the upper housing 101 and the lower housing 102. When disassembling, by pulling the two pull rods 109, the two pull rods 109 respectively drive the moving plates 104 to move. Each moving plate 104 disengages the extrusion arc block 107 from the fixing hole 111 of the insertion column 103, and then separates the upper housing 101 and the lower housing 102. Through the above method, the upper housing 101 and the lower housing 102 can be quickly connected and fixed, with simple operation and convenient subsequent disassembly.

[0030] Second Embodiment

[0031] Please refer to Figure 5 where Figure 5 is the overall structural schematic diagram of the second embodiment.

[0032] On the basis of the first embodiment, a dust-proof component is further included in an electric vehicle controller housing of the present invention. The dust-proof component includes a dust-proof net 201, an iron ring 202, a magnetic ring 203, and a pull block 204.

[0033] The dust-proof component is arranged outside the heat dissipation window 112. By providing the protection component outside the heat dissipation window 112, the dust-proof component can block and filter dust outside the heat dissipation window 112 to prevent dust from entering the housing through the heat dissipation window 112.

[0034] The magnetic ring 203 is fixedly connected to the lower housing 102 and is located on the lower housing 102. The iron ring 202 is magnetically attracted to the magnetic ring 203. The dustproof net 201 is fixedly connected to the iron ring 202 and is located outside the heat dissipation window 112. By the magnetic attraction between the iron ring 202 and the magnetic ring 203, the dustproof net 201 is fixed outside the heat dissipation window 112. The dustproof net 201 will block the dust in the air outside the heat dissipation window 112, preventing the dust from entering the shell through the heat dissipation window 112 and accumulating, which is beneficial to the operation of the controller in the shell.

[0035] The pulling block 204 is fixedly connected to the dustproof net 201 and is located on the outer side wall of the dustproof net 201. By providing the pulling block 204 on the outer side of the dustproof net 201, the pulling block 204 can be used to facilitate the pulling of the dustproof net 201.

[0036] By the magnetic attraction between the iron ring 202 and the magnetic ring 203, the dustproof net 201 is fixed outside the heat dissipation window 112. The dustproof net 201 will block the dust in the air outside the heat dissipation window 112, preventing the dust from entering the shell through the heat dissipation window 112 and accumulating, which is beneficial to the operation of the controller in the shell. When disassembling the dustproof net 201 from the outside of the heat dissipation window 112, by applying an outward pulling force on the pulling block 204, the pulling block 204 drives the dustproof net 201 to separate from the heat dissipation window 112.
