[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] Example 1

[0044] See Figure 1-5 , a mounting bracket for a new energy vehicle motor controller, comprising a mounting plate 1, on which an adjustment fixing assembly 2 is provided, the adjustment fixing assembly 2 comprising: a bidirectional screw rod 21, rotatably connected to the groove at the bottom of the mounting plate 1, the right end of the bidirectional screw rod 21 passing through the right side of the mounting plate 1; a hand wheel 211, fixedly connected to the right end of the bidirectional screw rod 21; a threaded block 212, symmetrically and threadedly connected to the bidirectional screw rod 21; a connecting plate 221, symmetrically fixedly connected to the bottom of the threaded block 212; a support plate 22, symmetrically arranged at the bottom of the connecting plate 221; a rod body 23, It is slidably connected to the support plate 22, and the opposite ends of the rod body 23 pass through the support plate 22; the plate body 24 is fixedly connected to the opposite ends of the rod body 23; the sliding rod 241 passes through the plate body 24 arranged on the same side, and the plate body 24 is slidably connected to the sliding rod 241; the rotating shaft 251 is rotatably connected to the inside of the support plate 22; the gear 25 is fixedly connected to the outside of the rotating shaft 251; the rack 26 is symmetrically opened on the opposite surfaces of the rod body 23, and the gear 25 is engaged with the rack 26 on both sides; the limiting mechanism 27 is arranged on the support plate 22 and the rod body 23. The limiting mechanism 27 includes: a limiting groove 271 symmetrically formed at the bottom of the rod body 23; a bracket 272 fixedly connected to the outer wall of the support plate 22; a pull rod 273 extending through the bracket 272; a limiting block 274 fixedly connected to the end of the pull rod 273 near the limiting groove 271, with the limiting block 274 having an inclined surface on the side near the plate body 24; and a spring 275 fixedly connected between the limiting block 274 and the bracket 272. The spring 275 is sleeved on the outside of the pull rod 273. The limiting mechanism 27 is symmetrically provided in multiple groups.

[0045] When in use, the staff adjusts the distance between the support plate 22 and the plate body 24 according to the size of the motor controller: the staff rotates the hand wheel 211, the hand wheel 211 drives the bidirectional screw rod 21 to rotate, and the threaded block 212 threadedly connected to the bidirectional screw rod 21 drives the connecting plate 221 and the support plate 22 to move closer to or away from each other according to the different rotation directions of the bidirectional screw rod 21, and adjusts the distance between the support plates 22 to be slightly larger than the length of the motor controller. The staff places the motor controller on the support plate 22, and then rotates the hand wheel 211 to The spacing between the support plates 22 is finely adjusted. When the spacing between the support plates 22 changes, the plates 24 on both sides slide on the slide bars 241, and then pull the plates 24. The plates 24 drive the rods 23 to extend or retract into the support plates 22. When the two rods 23 on one side extend out of the support plates 22, the racks 26 on the rods 23 drive the gears 25 to rotate, and the racks 26 on the other side of the gears 25 engage with the rods 23 on the other side to also extend out of the support plates 22. Similarly, when the plates 24 are pushed, the rods 23 on both sides are simultaneously retracted into the support plates 22. , to adjust the spacing between the plates 24. When the plates 24 are adjusted to fit the outside of the motor controller, the limiting mechanism 27 limits the position of the rod 23 to increase the stability of the plate 24 after it is fixed: when the spacing between the plates 24 needs to be reduced, the staff pushes the plate 24 toward the support plate 22. At this time, the limiting groove 271 on the rod 23 passes through the inclined surface of the limiting block 274, pushing the limiting block 274 toward the bracket 272. The spring 1 275 is compressed, and when the plate 24 is adjusted to the appropriate position, it no longer moves further. When the rod 23 moves, the spring 275, which generates elastic force after deformation, pushes the limit block 274 into the limit slot 271, restricting the movement of the rod 23 toward the support plate 22. When the distance between the plates 24 needs to be increased, the staff first pulls the pull rod 273, which drives the limit block 274 out of the limit slot 271. At this time, the rod 23 is no longer restricted and can continue to extend. When the plate 24 has completed its movement, the pull rod 273 is released, and the limit block 274 springs into the limit slot 271, once again restricting the position of the rod 23. The limit mechanism 27 is provided with multiple groups, so that multiple limit blocks 274 restrict the rod 23, increasing the firmness of the plate 24 after it fixes the motor controller.

[0046] Example 2

[0047] On the basis of the first embodiment, an auxiliary function is added.

[0048] See Figure 1-5Each set of connecting plates 221 and each set of facing plates 24 are equipped with springs 31. The facing ends of the springs 31 are fixedly connected to the fixing plates 3. The fixing plates 3 are provided with heat dissipation holes. Side plates 42 are symmetrically arranged on the outer walls of the support plates 22. The optical axis 4 is fixedly connected between the side plates 42. Sliders 41 are symmetrically arranged on the outer walls of the limit blocks 274. The optical axis 4 passes through these slides 41 and is slidably connected to the optical axis 4.

[0049] After the connection plate 221 and the plate body 24 are adjusted, the fixing plate 3 contacts the outer wall of the motor controller, and the spring 2 31 contracts accordingly. When the car is running, the fixing plate 3 and the spring 2 31 allow the motor controller to have a certain amount of space for movement, which is used to increase the shock absorption effect of the motor controller and prevent the motor controller from being bumped. The heat dissipation holes on the fixing plate 3 not only absorb the shock of the motor controller but also ventilate and dissipate heat to the contact parts, thus preventing the motor controller from overheating and malfunctioning. When the limit block 274 moves, the sliders 41 on both sides slide on the optical axis 4. The optical axis 4 and the slider 41 are used to increase the stability of the limit block 274 when it moves, so that the limit block 274 can be timely and accurately ejected into the limit groove 271, thereby avoiding affecting the rapid fixing effect of the rod body 23.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
