Description

Technical Field

[0001] The present invention relates to the technical field of mechatronics, and in particular to a protection device for a mechatronics motor. Background Art

[0002] Mechatronics, also known as mechatronics, is an important branch of mechanical engineering and automation. It combines knowledge from multiple disciplines such as mechanical engineering, electronic engineering, computer science, and control theory. Mechatronics combines mechanical technology with electronic technology and information technology to achieve intelligent and automated control of mechanical systems through computer control, sensor detection, actuator drive, etc. This technology emphasizes the integration of mechanical and electronic technologies, as well as the precise control of the entire mechanical system.

[0003] In the mechatronic system, the motor is not just a single component, but the core of the entire system, bearing the heavy responsibility of driving and controlling. Therefore, it is very important to protect the motor. The motor is generally set in a protective shell. Due to the existence of the protective shell, the heat dissipation efficiency and ventilation efficiency of the motor are reduced. The existing device cannot adjust the heat dissipation according to the temperature of the motor when the motor is working, resulting in low heat dissipation efficiency of the motor. In the long run, the life of the motor will be reduced. Improvements need to be made to this problem. Summary of the invention

The adjustment frame is rotatably connected to the middle of the rotating block, the working plate is fixedly connected to the side of the adjustment frame away from the movable guide ring, and the ball fan is arranged in the middle of the working plate.

[0009] According to the above technical scheme, the auxiliary ventilation assembly includes a fixed plate, an airbag, an extrusion frame, a connecting pipe, an auxiliary ventilation box, a sealing ring, a second spring and a movable baffle, the fixed plate is fixedly connected to the inner wall of the back side of the protective shell, the airbag is fixedly connected to the inner side of the fixed plate, the extrusion frame is fixedly connected to the front side of the working plate and is located away from the rotating block, the connecting pipe is fixedly connected to the front side of the airbag, the auxiliary ventilation box is fixedly connected to the end of the connecting pipe away from the airbag, the second spring is fixedly connected to the inner wall of the back side of the auxiliary ventilation box, the second spring is fixedly connected to the inner walls on the left and right sides of the protective shell, and the movable baffle is fixedly connected to the front end of the second spring.

[0010] According to the above technical solution, a sliding groove is provided in the movable guide ring, and the movable guide ring is slidably connected to the outer wall of the guide cylinder through the sliding groove.

[0011] According to the above technical solution, the telescopic end of the electric telescopic rod passes through the back of the guide cylinder and extends into the guide cylinder to be fixedly connected to the back of the movable guide ring. The outer wall of the guide cylinder is provided with a rectangular groove for accommodating the movement of a spring.

[0012] According to the above technical solution, a rotation groove is opened in the middle of the working plate, the ball fan is arranged in the rotation groove, a rotation hole is opened on the side of the working plate away from the adjustment frame, and the working plate is rotatably connected to the positioning frame through the rotation hole.

[0013] According to the above technical solution, ventilation slots 2 are provided on both sides of the protective shell, a piston plate is provided on the rear side of the movable baffle, and the movable baffle is slidably connected to the inner wall of the auxiliary ventilation box through the piston plate.

[0014] According to the above technical solution, the number of the spring 1, rotating block, adjusting frame, working plate and ball fan is four, and the four springs 1, rotating block, adjusting frame, working plate and ball fans are distributed in a ring outside the guide tube.

[0015] According to the above technical solution, the motor has an output shaft, a driving hole is opened on the front side of the protective shell, and the motor output shaft passes through the driving hole and extends to the front side of the protective shell.

[0016] According to the above technical solution, the side of the auxiliary ventilation box that contacts the inner wall of the protective shell is fixedly connected to the inner wall of the protective shell, the sealing ring is located on the outside of the ventilation groove, and a sealing groove corresponding to the movable baffle is opened on the inside of the sealing ring. The interior of the auxiliary ventilation box is connected to the airbag through a connecting pipe.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: when the motor needs to work, the present invention controls the motor to work so that the motor output shaft rotates; when the inside of the protective shell needs to be ventilated, the ball fan in the working plate is controlled to work so that the ventilation slot 1 at the top of the protective shell draws the outside air into the inside of the protective shell, and finally sends the air out through the ball fan, thereby accelerating the air flow inside the protective shell and ensuring the heat dissipation efficiency of the motor at the same time; by setting the ventilation slot 1, it is ensured that the noise generated by the motor during operation can be better suppressed to avoid excessive noise;

[0018] As the use time increases, when the temperature generated by the motor is high, the air entering the ventilation slot and the ball fan cannot effectively cool the motor. The electric telescopic rod is controlled to work. When the electric telescopic rod is working, the electric telescopic rod drives the movable guide ring to move. At this time, the movable guide ring moves along the outer wall of the guide cylinder, so that the spring is stretched and the rotating block rotates in the adjustment frame. When the rotating block moves, it pulls the adjustment frame to make the ball fan on the working plate rotate in the storage slot, so that the working plate is tilted relative to the storage slot, reducing the resistance section of the working plate to the storage slot. At this time, the four ball fans are tilted towards the middle of the back of the protective shell at the same time, and the ball fans are controlled to work, so that the suction force of the middle of the back of the protective shell is increased, thereby accelerating the absorption of the temperature inside the protective shell.

[0019] When the working plate is tilted, the extrusion frame on the working plate is separated from the airbag. At this time, the airbag recovers elastically, so that the negative pressure generated in the airbag is introduced into the auxiliary ventilation box through the connecting pipe, and the second spring in the auxiliary ventilation box recovers elastically. At this time, the movable baffle moves and is stored in the auxiliary ventilation box, exposing the second ventilation slot on the outside of the protective shell, so that the number of ventilated places on the outside of the protective shell increases to three, so that the total amount of air entering the protective shell can be increased, and at the same time, the ball fan works to quickly cool the temperature in the protective shell;

[0020] After the motor finishes working, the electric telescopic rod is controlled to work, so that the electric telescopic rod drives the working plate to reset during work. During the resetting process of the working plate, the extrusion frame on the working plate contacts and squeezes the airbag, so that the air in the airbag is introduced into the auxiliary ventilation box through the connecting pipe. At this time, the pressure in the auxiliary ventilation box increases, causing the second spring to stretch, and at the same time, the baffle is moved out of the auxiliary ventilation box, and the moving baffle contacts the sealing ring. The moving baffle and the sealing ring cooperate with each other to seal the two ventilation grooves on the outside of the protective shell, ensuring that the protective shell can have a certain noise reduction function for the motor during normal work.

[0040] A rotation groove is opened in the middle of the working plate 502, and the ball fan 503 is arranged in the rotation groove. A rotation hole is opened on the side of the working plate 502 away from the adjustment frame 501, and the working plate 502 is rotatably connected to the positioning frame 402 through the rotation hole.

[0041] The protective housing 1 is provided with ventilation slots 2 on both sides. A piston plate is provided on the rear side of the movable baffle 609. The movable baffle 609 is slidably connected to the inner wall of the auxiliary ventilation box 605 through the piston plate.

[0043] The motor 2 has an output shaft, and a driving hole is opened on the front side of the protective housing 1. The output shaft of the motor 2 passes through the driving hole and extends to the front side of the protective housing 1.

[0044] The side of the auxiliary ventilation box 605 that contacts the inner wall of the protective shell 1 is fixedly connected to the inner wall of the protective shell 1, the sealing ring 606 is located outside the ventilation groove, and a sealing groove corresponding to the movable baffle 609 is opened on the inner side of the sealing ring 606. The interior of the auxiliary ventilation box 605 is connected to the airbag 602 through the connecting pipe 604.

[0045] When the motor 2 needs to work, the motor 2 is controlled to work so that the output shaft of the motor 2 rotates. When the interior of the protective shell 1 needs to be ventilated, the ball fan 503 in the working plate 502 is controlled to work so that the ventilation slot 3 on the top of the protective shell 1 draws the outside air into the interior of the protective shell 1, and finally sends the air out through the ball fan 503, thereby accelerating the air flow inside the protective shell 1 and ensuring the heat dissipation efficiency of the motor 2. By setting the ventilation slot 3, the noise generated by the motor 2 during operation can be better suppressed to avoid excessive noise.

[0046] As the use time increases, when the temperature generated by the motor 2 is high, the air entering the ventilation slot 3 and the ball fan 503 are difficult to effectively cool the motor 2, and the electric telescopic rod 404 is controlled to work. When the electric telescopic rod 404 is working, the electric telescopic rod 404 drives the movable guide ring 405 to move. At this time, the movable guide ring 405 moves along the outer wall of the guide cylinder 403, so that the spring 1 406 is stretched, and the rotating block 407 rotates in the adjustment frame 501 at the same time. The rotating block 407 pulls the adjustment frame 501 when moving, so that the ball fan 503 on the working plate 502 rotates in the storage groove 401, so that the working plate 502 is tilted relative to the storage groove 401, reducing the resistance section of the working plate 502 to the storage groove 401. At this time, the four ball fans 503 are tilted towards the middle part of the back side of the protective shell 1 at the same time, and the ball fans 503 are controlled to work, so that the suction force in the middle part of the back side of the protective shell 1 is increased, thereby accelerating the absorption of the internal temperature of the protective shell 1.

[0047] When the working plate 502 is tilted, the extrusion frame 603 on the working plate 502 is separated from the airbag 602. At this time, the airbag 602 is elastically restored, so that the negative pressure generated in the airbag 602 is introduced into the auxiliary ventilation box 605 through the connecting pipe 604, and the spring 2 608 in the auxiliary ventilation box 605 is elastically restored. At this time, the movable baffle 609 is moved and stored in the auxiliary ventilation box 605, exposing the ventilation slot 2 on the outside of the protective shell 1, so that the ventilated places on the outside of the protective shell 1 are increased to three, so that the total amount of air entering the inside of the protective shell 1 can be increased, and at the same time, with the work of the ball fan 503, the temperature inside the protective shell 1 can be quickly cooled down.

[0048] After the motor 2 finishes working, the electric telescopic rod 404 is controlled to work, so that the electric telescopic rod 404 drives the working plate 502 to reset during operation. During the resetting process of the working plate 502, the extrusion frame 603 on the working plate 502 contacts and squeezes the airbag 602, so that the air in the airbag 602 is introduced into the auxiliary ventilation box 605 through the connecting pipe 604. At this time, the pressure in the auxiliary ventilation box 605 increases, so that the spring 2 608 is stretched, and at the same time, the movable baffle 609 is moved out of the auxiliary ventilation box 605, and the movable baffle 609 contacts the sealing ring 606. The movable baffle 609 and the sealing ring 606 cooperate with each other to seal the two ventilation grooves on the outside of the protective shell 1, thereby ensuring that the protective shell 1 can have a certain noise reduction function for the motor 2 during normal operation.
