Description

Technical Field

[0001] The utility model belongs to the technical field of motor controllers, and in particular relates to a motor controller with good waterproof performance. Background Art

[0002] A motor controller plays a key role in motor operation. It possesses a high degree of intelligence and precision. It precisely controls motor parameters such as speed, direction, and torque to meet the needs of diverse applications. Using advanced electronic technology and algorithms, it monitors the motor's operating status in real time and dynamically adjusts based on actual conditions, ensuring optimal operation.

[0003] Motor controllers with good water resistance typically meet a high IPX rating. For example, an IPX7 rating indicates that a motor controller can withstand immersion in 1 meter of water for 30 minutes without ingress; an IPX8 rating requires continued operation after immersion in deeper water for longer periods. This means that the housing structure and sealing design effectively prevent moisture from entering the controller from the external environment, preventing problems such as circuit shorts and component corrosion caused by water ingress.

[0004] However, in the prior art, when the DC motor is working, it is easy to generate vibration, which in turn causes vibration of the motor controller, causing the wire connection to fall off or loosen, affecting the normal operation of the motor. Utility Model Content

[0005] The purpose of the utility model is to provide a motor controller with good waterproof performance, so as to solve the problem in the prior art that the existing motor controller is not stable enough under vibration.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A motor controller with good waterproof performance includes a controller body, a wire is installed on the side wall of the controller body, an auxiliary mechanism is provided at the bottom of the controller body, the auxiliary mechanism includes a mounting plate arranged at the bottom of the controller body, a plurality of mounting holes are opened on the end surface of the mounting plate, a plurality of dampers are fixedly connected to the end surface of the mounting plate, the top end of the damper is fixedly connected to a square plate, a spring is sleeved on the arc surface of the damper, the two ends of the spring are respectively fixedly connected to the square plate and the mounting plate, a clamping plate is provided on the end surface of the square plate, and the clamping plate is fixedly connected to the surface of the controller body.

[0008] Preferably, a card slot is provided on one side of the card plate close to the square plate, and a card block is fixedly connected to the end surface of the square plate.

[0009] Preferably, the size of the clamping block is adapted to the size of the clamping slot, the cross section of the clamping block is cross-shaped, and the clamping block and the clamping slot are interference-fitted.

[0010] Preferably, a rectangular hole is formed on the bottom surface of the mounting plate, a filter is installed on the inner wall of the rectangular hole, and a protective frame is fixedly connected to the side wall of the controller body.

[0011] Preferably, the end surface of the controller body is fixedly connected to two fixing rods, and the arc surfaces of the two fixing rods are slidably connected to sliding racks.

[0012] Preferably, a limiting groove is provided on the side wall of the sliding frame, and the inner wall of the limiting groove is inclined.

[0013] Preferably, a fixed block is fixedly connected to the surface of the sliding frame, and a screw is threadedly connected to the end surface of the fixed block.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model provides a damper, a spring, a card block and a card slot. The rational use of the damper and the spring can significantly improve the anti-vibration effect of the controller. In practical applications, the damper can effectively absorb vibration energy and reduce the transmission of vibration; the spring can act as a buffer to further reduce the vibration impact on the controller. Such a combination can avoid the situation where the wires on the controller are easily fallen off due to vibration to the greatest extent, ensuring the normal operation of the controller and the stability of signal transmission. At the same time, through the clever coordination of the card block and the card slot, the controller can be quickly disassembled. This design not only facilitates the installation and maintenance of the controller, but also improves work efficiency, bringing great convenience to users.

[0016] 2. This utility model utilizes a filter and a sliding frame, and the excellent permeability of the filter to significantly improve ventilation at the bottom of the controller. The filter allows air to circulate freely, preventing heat buildup at the bottom of the controller due to poor air circulation, thereby ensuring that the controller maintains a relatively suitable temperature during operation. Furthermore, the flexible movement of the sliding frame allows for adjustment based on the length of the wires, effectively limiting their position. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0023] Reference Figures 1-4 As shown, the utility model provides a motor controller with good waterproof performance, including a controller body 1, a wire 11 is installed on the side wall of the controller body 1, an auxiliary mechanism 2 is provided at the bottom of the controller body 1, and the auxiliary mechanism 2 includes a mounting plate 21 arranged at the bottom of the controller body 1, and a plurality of mounting holes 2101 are opened on the end face of the mounting plate 21, and a plurality of dampers 22 are fixedly connected to the end face of the mounting plate 21, and a square plate 24 is fixedly connected to the top end of the damper 22, and a spring 23 is sleeved on the arc surface of the damper 22, and both ends of the spring 23 are fixedly connected to the square plate 24 and the mounting plate 21 respectively, and a clamping plate 26 is provided on the end face of the square plate 24, and the clamping plate 26 is fixedly connected to the surface of the controller body 1.

[0024] In this embodiment, the controller body 1 is an existing device, which has waterproof capabilities. The shell is made of special waterproof material, which can effectively prevent the intrusion of moisture. Even in a humid or even water-soaked environment, it can ensure the safe operation of the internal circuit, and each interface and gap has been strictly sealed to prevent moisture from penetrating into the controller from any tiny place. The damper 22 can effectively absorb vibration energy and reduce the transmission of vibration; the spring 23 can play a buffering role to further reduce the vibration impact on the controller.

[0025] A slot 27 is formed on one side of the card plate 26 near the square plate 24, and a block 25 is fixedly connected to the end face of the square plate 24. The size of the block 25 matches the size of the slot 27, and the cross-section of the block 25 is cross-shaped, and the block 25 and the slot 27 have an interference fit.

[0026] In this embodiment, the controller can be quickly disassembled through the clever cooperation of the block 25 and the slot 27. This design not only facilitates the installation and maintenance of the controller, but also improves work efficiency and brings great convenience to the user.

[0027] A rectangular hole is formed on the bottom surface of the mounting plate 21 , a filter screen 28 is installed on the inner wall of the rectangular hole, and a protective frame 29 is fixedly connected to the side wall of the controller body 1 .

[0028] In this embodiment, the filter 28 serves to improve the ventilation effect at the bottom of the controller body 1, and the protective frame 29 is made of rubber material, which serves to prevent the wire 11 from being damaged when it comes into contact with the wire 11 when the wire 11 is bent.

[0029] Two fixed rods 210 are fixedly connected to the end faces of the controller body 1. Sliding brackets 211 are slidably connected to the arcuate surfaces of the two fixed rods 210. The side walls of the sliding brackets 211 define limiting grooves 212, whose inner walls are inclined. A fixing block 213 is fixedly connected to the surface of the sliding bracket 211, and a screw 214 is threadedly connected to the end face of the fixing block 213.

[0030] In this embodiment, the sliding frame 211 can be flexibly moved to adjust the lengths of the wires 11 accordingly, thereby facilitating effective positioning of the wires 11 .

[0031] The working principle of the present invention is as follows: when in use, the staff inserts the bolts into the mounting plate 21 through the mounting hole 2101 to fix it in the appropriate position, then aligns the card plate 26 on the controller body 1 with the square plate 24, that is, the card block 25 will face the card slot 27. After pressing it in, the controller body 1 will contact the filter screen 28. Then the position of the sliding frame 211 can be adjusted according to the length of the wire 11. After the position of the sliding frame 211 is adjusted, the screw 214 is screwed and the screw 214 is driven by the thread until the screw 214 contacts the end face of the controller body 1 to stabilize the sliding frame 211. Then the wire 11 passes through the bottom of the sliding frame 211 and then wraps it back from the top to limit the wire 11, and try to avoid the situation where the wire 11 is too long and easily messy. At this time, the wire 11 will be inside the limiting groove 212, and the limiting groove 212 plays a role in limiting the wire 11.

[0032] Although the 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.
