Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figures 1-3 The connecting mechanism shown includes a fixed base plate 200 installed at the bottom of an electric vehicle controller housing 100. The fixed base plate 200 extends to the outer sides of the electric vehicle controller housing 100 at both ends and has fastening through holes 201. Positioning baffles 202 are located on both sides of the electric vehicle controller housing 100 and are fixedly connected to the top of the fixed base plate 200. A snap-fit ​​assembly is disposed between the electric vehicle controller housing 100 and the positioning baffles 202, and is used to limit the movement between the electric vehicle controller housing 100 and the positioning baffles 202. The fixed base plate 200 has fastening through holes 201 that allow screws to pass through and, with the help of nuts, fix the fixed base plate 200 to the frame of the electric vehicle. Then, the blocking effect of the two positioning baffles 202 on the fixed base plate 200 forms a... A positioning range is provided for the installation of the electric vehicle controller housing 100. This allows the electric vehicle controller housing 100 to be snapped into place between two positioning baffles 202 on the fixed base plate 200. With the help of the snap-fit ​​assembly, the electric vehicle controller housing 100 and the positioning baffles 202 are locked together, making the electric vehicle controller housing 100 detachable between the two positioning baffles 202. This facilitates the removal of the electric vehicle controller housing 100 from the fixed base plate 200 for maintenance, simplifying the disassembly and assembly steps of the electric vehicle controller housing 100 and improving the convenience of disassembly, assembly, and maintenance. At the same time, it avoids the disassembly and assembly of the fixed base plate 200 and the electric vehicle frame, eliminating the need for repeated disassembly and assembly of the screws and nuts on the fixed base plate 200 and maintaining the stability of the fixed base plate 200.

[0027] The locking assembly includes two locking crossbars 103 and a return spring 104. The two locking crossbars 103 are slidably disposed on the bottom of the electric vehicle controller housing 100, with their ends extending from the side walls of the electric vehicle controller housing 100. A locking groove 203 is provided on the positioning baffle 202, and the cross-section of the locking groove 203 is convex. The return spring 104 is fixedly disposed between the two locking crossbars 103. When the electric vehicle controller housing 100 is installed on the fixed base plate 200, the two locking crossbars 103 are simply pressed together to bring them closer. This allows the ends of the two locking crossbars 103 to be inserted into the locking grooves 203, and the electric vehicle controller housing 100 is positioned on the two positioning baffles 202. After the locking crossbar 103 is positioned between the two positions, it extends into the bottom position of the locking slot 203. Then, the pressing force on the locking crossbar 103 is released, causing the locking crossbars 103 to automatically move away from each other through the return spring 104. This allows the end of the locking crossbar 103 to be engaged with the bottom end position of the locking slot 203, achieving a limit lock between the electric vehicle controller housing 100 and the positioning baffle 202. This ensures that the electric vehicle controller housing 100 is securely installed on the fixed base plate 200. Furthermore, during disassembly, it is only necessary to manually press the two locking crossbars 103 so that they can be pulled out from the top port of the locking slot 203. This makes the disassembly and assembly of the electric vehicle controller housing 100 between the two positioning baffles 202 on the fixed base plate 200 more convenient and efficient.

[0028] Furthermore, the bottom of the electric vehicle controller housing 100 is provided with a mounting cavity 101, and the locking crossbar 103 is movably disposed inside the mounting cavity 101. Straight through slots 102 communicating with the mounting cavity 101 are provided on both sides of the electric vehicle controller housing 100. The end of the locking crossbar 103 passes through the straight through slot 102 and extends to the outside. A sliding seat 105 is fixedly connected to the outer wall of the mounting cavity 101 and located inside the mounting cavity 101. The outer wall of the sliding seat 105 is slidably connected to the inner wall of the mounting cavity 101. A return spring 104 is fixedly connected to the phase... The mounting cavity 101 and the straight through groove 102 between the two sliding seats 105 at the corresponding positions can accommodate the locking crossbar 103 and the return spring 104, so that the locking crossbar 103 can be stably installed on the electric vehicle controller housing 100 for convenient use. The sliding seats 105 can provide auxiliary support for the movement of the locking crossbar 103 in the mounting cavity 101, making the movement of the locking crossbar 103 in the mounting cavity 101 more stable and smooth, and allowing the return spring 104 to stably drive the locking crossbar 103 to return to its original position.

[0029] In addition, a positioning component is provided between the electric vehicle controller housing 100 and the positioning baffle 202. The positioning component is used to position the electric vehicle controller housing 100 on the fixed base plate 200. The positioning component includes a limiting block 106, which is fixedly connected to the bottom of the side wall of the electric vehicle controller housing 100. The length of the limiting block 106 is adapted to the length of the top port of the locking slot 203. When the electric vehicle controller housing 100 is positioned between the two positioning baffles 202 on the fixed base plate 200, the limiting block 106 is engaged with the port of the locking slot 203. This ensures the accuracy of the electric vehicle controller housing 100's installation and positioning on the fixed base plate 200, and also limits the movement between the electric vehicle controller housing 100 and the positioning baffle 202, thereby further improving the stability of the electric vehicle controller housing 100's installation on the fixed base plate 200.

[0030] In other embodiments, an electric vehicle controller is also provided, including the connection mechanism described above.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
