Technical Field

[0001] This utility model relates to the field of electric vehicle motor controller technology, specifically a motor controller fixing device. Background Technology

[0002] The electric vehicle motor controller is one of the key components of an electric vehicle, primarily responsible for controlling the motor's operation. Like the motor's "brain," it precisely controls parameters such as current, voltage, and speed based on the driver's intentions and the vehicle's operating status, ensuring the motor functions as required.

[0003] The aforementioned device lacks a structure for quick adaptation and installation of different controllers. This makes it difficult to stably install the existing motor controller in the vehicle body when replacing it with an aftermarket or other model controller after the original electric vehicle controller is damaged, if the mounting holes of the replacement controller do not match the original vehicle's mounting holes. Based on the shortcomings of the existing technology, this utility model designs a motor controller fixing device. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-4 A motor controller fixing device includes a controller body 1, a fixing frame 2 sleeved on the outer side of the controller body 1, a fixing mechanism 3 at the bottom of the fixing frame 2 to facilitate adaptation to different mounting hole positions, a side heat dissipation fin 101 fixedly connected to the side of the controller body 1, a front panel 102 fixedly connected to the front of the controller body 1, a control line 103 provided on the front panel 102, and the control line 103 electrically connected to the inside of the controller body 1.

[0022] Please see Figure 4 The fixing mechanism 3 includes a fixing plate 301, a movable groove 302, an adjusting plate 303, a side groove 304, a long groove 305, and a bolt 306. The fixing plate 301 is fixedly connected to the lower surface of the fixing frame 2. The movable groove 302 is opened through the fixing plate 301. The adjusting plate 303 is slidably connected to the inside of the movable groove 302. The side groove 304 is opened at both ends of the adjusting plate 303. The long groove 305 is opened through the upper surface of the adjusting plate 303. The bolt 306 is inserted through the long groove 305. The side groove 304 is slidably engaged with the edge of the movable groove 302.

[0023] By setting a fixed plate 301, a movable groove 302, an adjusting plate 303, and a side groove 304, the position of the long groove 305 can be adjusted left and right to match different mounting hole positions on the left and right sides of the vehicle. By setting the long groove 305, it can be matched with different mounting hole positions on the front and rear sides of the vehicle. By setting a bolt 306, it can be inserted into the long groove 305 to connect and fix it to the mounting hole in the vehicle.

[0024] Please see Figure 3 The top of the fixed frame 2 is provided with a threaded hole 201, and a threaded post 202 is threaded into the inside of the threaded hole 201. A rotating seat 203 is fixedly connected to the bottom of the threaded post 202. A clamping plate 204 is rotatably connected to the bottom of the rotating seat 203. A rubber anti-slip plate is provided at the bottom of the clamping plate 204. The clamping plate 204 is clamped on the upper surface of the controller body 1 and can move up and down inside the fixed frame 2.

[0025] By setting a fixed frame 2, it is possible to fit and position the controller body 1 of different sizes. By setting a threaded hole 201, a threaded post 202 and a clamping plate 204, the threaded hole 201 can be used to control the lifting and pushing of the clamping plate 204 to clamp the upper surface of the controller body 1 when the threaded post 202 is rotated. By setting a rotating seat 203, after the clamping plate 204 contacts the upper surface of the controller body 1, the threaded post 202 can continue to rotate and move downward to push the clamping plate 204 to increase the clamping force.

[0026] Working principle: When a motor controller fixing device is used, in the initial state, the front panel 102 is first fixedly connected to the front side of the controller body 1, and the control line 103 connected to the front panel 102 is connected to the electronic components inside the controller body 1 to control the electric vehicle. The fixing frame 2 sleeved on the outside of the controller body 1 has a threaded hole 201. The threaded column 202 rotatably connected in the threaded hole 201 is also connected to a rotating seat 203 and a clamping plate 204 to clamp and fix the controller body 1 of different sizes. At the same time, the fixing plate 301 fixedly connected to the bottom of the fixing frame 2 has a movable groove 302. The adjusting plate 303 slidably connected in the movable groove 302 has a long groove 305 connected to a bolt 306 to fix the fixing frame 2 and the controller body 1 inside the electric vehicle.

[0027] When it is necessary to fix controller bodies 1 of different sizes inside the electric vehicle, first insert the controller body 1 into the inside from one side of the fixing frame 2, then turn the threaded post 202 clockwise so that it moves downward through the threaded hole 201 to push the clamping plate 204 to contact the upper surface of the controller body 1 and clamp and fix it. After the controller body 1 is fixed in the fixing frame 2, connect the control line 103 to the internal wiring of the electric vehicle. At this time, place the controller body 1 and the fixing frame 2 inside the electric vehicle, and adjust the adjusting plate 303 left and right according to the original screw hole installation position so that the long groove 305 on the adjusting plate 303 coincides with the screw hole position. Finally, insert the bolt 306 into the long groove 305 according to the screw hole position and screw it into the screw hole to tighten and fix it. This device makes it easy to fix controller bodies 1 of different sizes inside the electric vehicle.
