Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, and in particular to a motor controller fixing device. Background Technology

[0002] A motor controller is an integrated circuit that actively controls the motor to work according to a set direction, speed, angle, and response time. In electric vehicles, the function of the motor controller is to convert the electrical energy stored in the power battery into the electrical energy required to drive the motor according to commands such as gear, throttle, and brake. This controls the starting and running of the electric vehicle, its forward and reverse speed, climbing force, and other driving states. It can also assist the electric vehicle in braking and store some braking energy in the power battery. It is one of the key components of electric vehicles.

[0003] Traditional motor controllers have multiple mounting slots on both sides of the bottom extension, which are fixed by screwing bolts. Due to the large number of bolts, each bolt needs to be screwed on individually, and they are easily corroded and difficult to tighten after being exposed to the outside for a long time. This makes the disassembly and assembly of the motor controller cumbersome and inconvenient to maintain. Therefore, a motor controller fixing device is needed to meet people's needs. Utility Model Content

[0004] The purpose of this utility model is to provide a motor controller fixing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a motor controller fixing device, comprising a first base plate, a second base plate, and a motor controller. Two first mounting slots are formed on both sides of the first base plate, and two second mounting slots are formed on both sides of the extended section of the motor controller. The second mounting slots correspond vertically to the first mounting slots and have the same specifications. Several springs are provided between the top end of the first base plate and the bottom end of the second base plate. Bidirectional screws are rotatably connected to both sides of the second base plate. First moving blocks and second moving blocks are threaded onto the bidirectional screws. The first moving blocks and second moving blocks are arranged symmetrically to each other, and each has a wedge-shaped block at its top. Two wedge-shaped blocks are symmetrically arranged in the two second mounting slots on the same extended section.

[0006] Preferably, a plurality of dampers are disposed between the first substrate and the second substrate, the number of dampers corresponding to the number of springs.

[0007] Preferably, a worm gear is rotatably connected inside the second substrate, one end of the worm gear is connected to a drive rod, the drive rod is rotatably connected to the outer end of the second substrate, and a hexagonal hole is opened on the outer side. A worm wheel is provided on one end of the bidirectional screw, and the worm wheel meshes with the worm gear.

[0008] Preferably, the first moving block has a positive thread hole adapted to the positive thread section of the bidirectional screw, and the second moving block has a negative thread hole adapted to the negative thread section of the bidirectional screw.

[0009] Preferably, a guide groove is formed on the second substrate, the guide groove is parallel to the bidirectional screw, the bidirectional screw is arranged in the guide groove, and the first moving block and the second moving block are both slidably adapted in the guide groove.

[0010] Preferably, a bellows cover is provided between one end of the first moving block and the guide groove, between the first moving block and the second moving block, and between the second moving block and the other end of the guide groove, with the bellows cover arranged at the upper opening of the guide groove.

[0011] The beneficial effects of this utility model are: In this invention, the first mounting groove on the first substrate and the initial second mounting groove on the motor controller are in the same position and have the same specifications, so that the fixing device can be installed and fixed at the initial position of the motor controller. By driving the bidirectional screw to move the wedge block horizontally, the end of the second mounting groove is clamped and pressed down, thereby achieving the clamping and fixing of the motor controller, which significantly improves the disassembly and assembly efficiency and effectively avoids the problems of cumbersome disassembly and assembly and inconvenient maintenance of traditional bolt tightening.

[0012] In this invention, the reverse thread characteristics of the bidirectional screw allow two symmetrically arranged wedge blocks to move synchronously towards or away from each other, enabling the two wedge blocks to adapt to mounting slots of motor controllers of different widths to a certain extent, thus exhibiting strong versatility.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-5 A motor controller fixing device includes a first base plate 1, a second base plate 2, and a motor controller 3. Two first mounting slots 4 are formed on both sides of the first base plate 1. Two second mounting slots 5 are formed on both sides of the extension section of the motor controller 3. The second mounting slots 5 are vertically aligned with the first mounting slots 4 and have the same specifications. Several springs 6 are provided between the top end of the first base plate 1 and the bottom end of the second base plate 2. Two bidirectional screws 7 are rotatably connected to both sides of the second base plate 2. The bidirectional screws 7 are threadedly connected to the first moving block 8 and the second moving block 9. The first moving block 8 and the second moving block 9 are symmetrically arranged and each has a wedge block 10 at its top. The two wedge blocks 10 are symmetrically arranged in the two second mounting slots 5 on the same extension section.

[0017] The fixing device is fixed to the original position where the motor controller 3 needs to be installed using the first mounting groove 4 on the first base plate 1 and bolts. The motor controller 3 is placed on the second base plate 2, and the wedge block 10 passes through the second mounting groove 5 of the extension section of the second base plate 2 to the top. The bidirectional screw 7 is rotated, and the first moving block 8 and the second moving block 9 respectively drive the corresponding connected wedge blocks 10 to move closer to each other. The bottom inclined surfaces of the two wedge blocks 10 gradually approach the ends of the two corresponding second mounting grooves 5, thereby clamping the extension section of the motor controller 3 on both sides. At the same time, the inclined surfaces make the extension section fit tightly against the second base plate 2, thus ensuring the horizontal and vertical stability of the motor controller 3 on the second base plate 2, significantly improving the disassembly and assembly efficiency, and effectively avoiding the cumbersome disassembly and assembly and inconvenient maintenance problems of traditional bolt tightening. In addition, the two symmetrically arranged wedge blocks 10 move synchronously towards or away from each other, so that the two wedge blocks 10 can be adapted to a certain extent to the second mounting grooves 5 of motor controller 3 with different widths, which has strong versatility.

[0018] Specifically, in this embodiment, a plurality of dampers 11 are provided between the first substrate 1 and the second substrate 2. The number of dampers 11 corresponds to the number of springs 6. The springs 6 and dampers 11 are connected in parallel, which can absorb high-frequency vibration energy and suppress rebound oscillation, thus protecting the precision components inside the motor controller 3.

[0019] Specifically, in this embodiment, a worm gear 12 is rotatably connected inside the second substrate 2. One end of the worm gear 12 is connected to a drive rod 13, which is rotatably connected to the outer end of the second substrate 2. A hexagonal hole is provided on the outer side. A worm wheel 14 is provided on one end of the bidirectional screw 7. The worm wheel 14 meshes with the worm gear 12. The self-locking effect between the worm wheel 14 and the worm gear 12 ensures the holding effect after the bidirectional screw 7 rotates, thereby improving the stability of the motor controller 3 after it is fixed.

[0020] Specifically, in this embodiment, the first moving block 8 is provided with a positive thread hole that matches the positive thread section of the bidirectional screw 7, and the second moving block 9 is provided with a negative thread hole that matches the negative thread section of the bidirectional screw 7.

[0021] Specifically, in this embodiment, a guide groove 15 is provided on the second substrate 2. The guide groove 15 is parallel to the bidirectional screw 7. The bidirectional screw 7 is arranged in the guide groove 15. The first moving block 8 and the second moving block 9 are both slidably adapted in the guide groove 15.

[0022] Specifically, in this embodiment, a bellows cover 16 is provided between one end of the first moving block 8 and the guide groove 15, between the first moving block 8 and the second moving block 9, and between the second moving block 9 and the other end of the guide groove 15. The bellows cover 16 is arranged at the upper opening of the guide groove 15. The telescopic effect of the bellows cover 16 ensures the movement effect of the first moving block 8 and the second moving block 9, while preventing dust from entering the transmission part of the bidirectional screw 7.

[0023] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
