Description

Technical Field

[0001] This utility model relates to the field of motor housings, and more particularly to protective housing structures for motors. Background Technology

[0002] Motor protective housing is a sealed shell manufactured using alloy die casting or sheet metal processes. It is used to isolate dust, moisture and mechanical impact, integrate heat dissipation fins and air ducts to optimize thermal management, ensure safe operation of motors in harsh environments, and extend service life. It is suitable for the protection of precision motors in industrial equipment, new energy vehicles, medical instruments and other applications.

[0003] Existing motor protective housing structures suffer from significant limitations due to the vastly different bolt hole positions on various mounting surfaces. Traditional structures require the design of dedicated mounting brackets for each surface, significantly increasing the workload for designers. This results in poor installation adaptability, low design efficiency, and when the motor is deployed outdoors, its open top structure is directly exposed to rain, snow, and falling objects. Rainwater infiltration can easily cause internal short circuits, while impacts from falling objects can directly damage the motor casing or critical components, leading to substantial downtime and maintenance costs.

[0004] Therefore, in response to the problems of existing motor protective housings requiring customized mounting bases due to differences in bolt hole positions, which increases design workload and reduces efficiency, and the open top cover being exposed to rain, snow, and falling objects, leading to short circuit damage and increased maintenance costs, there is an urgent need to design a new type of motor protective housing structure. Utility Model Content

[0005] To overcome the problems of existing motor protective housings requiring customized mounting brackets due to differences in bolt hole positions, which increases design workload and reduces efficiency, and open top covers being exposed to rain, snow, and falling objects, leading to short circuits and increased maintenance costs.

[0006] The technical solution of this utility model is as follows: a protective housing structure for a motor, including a motor housing; and a mounting base. The lower side of the outer surface of the motor housing is connected to the upper end of the mounting base. A sliding frame is fixedly connected to the lower end of the mounting base. Smooth rods are fixedly installed on both the left and right sides inside the sliding frame. Two sliders are slidably connected to the outer surfaces of the two smooth rods. A connecting plate is fixedly connected between the two sliders on the front and rear sides. When the sliders move, they drive the connecting plate to move. A connecting groove is provided at the upper end of the connecting plate. Symmetrical mounting platforms are fixedly installed on both the left and right ends of the mounting base. A lifting frame is fixedly installed on the upper end of the mounting platform. A sliding rod is fixedly installed in the middle of the lower end inside the lifting frame. A telescopic column is slidably connected to the outer surface of the sliding rod. A spring is fixedly installed on the outer side of the lower end inside the lifting frame. A protective canopy is fixedly installed on the upper end of the four telescopic columns. The upper end of the spring is connected to the lower end of the telescopic column. When the telescopic column moves and presses the spring, the spring will drive the telescopic column to move in the opposite direction. An expansion module is provided inside the protective canopy. A locking module is provided at the upper end of the slider. A heat dissipation module is provided on the outer surface of the motor housing. A dustproof module is provided at the rear end of the motor housing.

[0007] Preferably, by setting a guide rod, the slider is restricted to move only along the guide rod. When the slider moves, it drives the connecting plate to move, thereby adjusting the front and rear installation positions. Since the connecting groove is a long groove design, the fixing screw can slide inside, thereby adjusting the left and right installation positions. The two work together to adapt to the threaded hole positions on different mounting surfaces. By setting a protective canopy, the upper side of the motor housing can be protected, avoiding the threat to the motor from rain, snow, and falling objects when the motor is installed outdoors. When a falling object hits the protective canopy, the canopy will drive the telescopic column to move down. When the telescopic column moves down, it will compress the spring. The compressed spring will release elastic potential energy, thereby reducing the impact force of the falling object. Furthermore, by setting a sliding rod to control the spring's free movement... The degree of deviation is limited to prevent deviation when the spring is compressed, thereby achieving the purpose of adapting to different mounting surfaces and protecting against rain, snow, and falling objects from heights. This addresses the shortcomings of existing motor protective housing structures, which require the design of dedicated mounting brackets for each mounting surface due to the significant differences in bolt hole positions on different mounting surfaces. This significantly increases the workload of designers, resulting in poor installation adaptability, low design efficiency, and when the motor is deployed outdoors, its open top structure is directly exposed to rain, snow, and falling objects. Rainwater infiltration can easily cause internal short circuits in the motor, while impacts from falling objects can directly damage the motor casing or critical components, leading to significant downtime and maintenance costs.

[0008] Preferably, the locking module includes bolts, and the upper ends of the four sliders are provided with threaded holes, which are threadedly connected to the bolts. When the bolts rotate, they move up and down inside the threaded holes.

[0009] Preferably, the expansion module includes a lead screw, a groove is provided at the front end of the protective canopy, the right rear end of the groove is rotatably connected to the rear end of the lead screw, a knob is rotatably connected to the right rear end of the protective canopy, the knob is connected to the lead screw, the knob is used to drive the lead screw to rotate, and a sliding element is provided on the outer surface of the lead screw.

[0010] Preferably, the sliding component includes an extension canopy, which is threadedly connected to a lead screw, and the extension canopy moves when the lead screw rotates.

[0011] Preferably, a limit rod is fixedly installed on the left side of the rear end of the slide. The limit rod is slidably connected to the expansion shed. When the expansion shed moves, it will slide along the direction defined by the limit rod.

[0012] Preferably, the heat dissipation module includes a fan, and the outer surface of the motor housing has a ring array of several heat dissipation fins, with the rear end of the motor housing connected to the front end of the fan.

[0013] Preferably, the dustproof module includes a protective cover, with the rear end of the motor housing connected to the front end of the protective cover, and a mounting groove provided at the rear end of the protective cover, with a dustproof net installed inside the mounting groove.

[0014] The beneficial effects of this utility model are:

[0015] 1. The slider's movement trajectory is limited by the light rod, and the slider drives the connecting plate to adjust its front and back positions. Combined with the long groove design of the connecting slot, the fixing screw can slide in the groove to adjust its left and right positions. The two work together to accurately match the threaded hole positions of different mounting surfaces, without the need for custom accessories, and adapt to diverse installation needs.

[0016] 2. By installing a protective canopy on the upper side of the motor housing, the outdoor motor can be protected from the threat of rain, snow and falling objects from heights. When a falling object impacts the protective canopy, the canopy causes the telescopic column to move down and compress the spring. The spring releases its elastic potential energy to buffer the impact force. At the same time, the sliding rod restricts the spring's degree of freedom to prevent the spring from deviating during compression. This achieves physical isolation from rain and snow directly corroding the motor housing, while also intercepting the direct impact of falling objects from heights, effectively improving the motor's operational safety in harsh outdoor environments.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5This utility model provides an embodiment of a protective housing structure for a motor, including a motor housing 1 and a mounting base 2. The lower outer surface of the motor housing 1 is connected to the upper end of the mounting base 2. A sliding frame 3 is fixedly connected to the lower end of the mounting base 2. Smooth rods 4 are fixedly mounted on both the left and right sides inside the sliding frame 3. Two sliders 5 are slidably connected to the outer surfaces of the two smooth rods 4. A connecting plate 6 is fixedly connected between the two sliders 5 on the front and rear sides. When the sliders 5 move, the connecting plate 6 is driven to move. A connecting groove 7 is provided at the upper end of the connecting plate 6. Two symmetrical mounting platforms 8 are fixedly installed at both ends of the structure 2. A lifting frame 9 is fixedly installed on the upper end of the mounting platform 8. A sliding rod 10 is fixedly installed at the middle of the lower end of the lifting frame 9. Telescopic columns 11 are slidably connected to the outer surface of the sliding rod 10. Springs 12 are fixedly installed on the outer side of the lower end of the lifting frame 9. Protective canopies 13 are fixedly installed on the upper ends of the four telescopic columns 11. The upper end of the spring 12 is connected to the lower end of the telescopic column 11. When the telescopic column 11 moves and presses against the spring 12, the spring 12 will drive the telescopic column 11 to move in the opposite direction. The internal structure of component 3 includes an expansion module, the upper end of slider 5 includes a locking module, the outer surface of motor housing 1 includes a heat dissipation module, and the rear end of motor housing 1 includes a dustproof module. A guide rod 4 restricts slider 5 to move only along its path. When slider 5 moves, it moves connecting plate 6, allowing adjustment of the front and rear mounting positions. The elongated design of connecting groove 7 allows the fixing screws to slide internally, thus adjusting the left and right mounting positions. Together, these components can accommodate different threaded hole 14 positions on mounting surfaces. A protective canopy 13 is also included. The upper side of the motor housing 1 can be protected to prevent the motor from being threatened by rain, snow and falling objects when it is installed outdoors. When a falling object falls on the protective canopy 13, the protective canopy 13 will drive the telescopic column 11 to move down. When the telescopic column 11 moves down, it will compress the spring 12. The compressed spring 12 will release elastic potential energy, thereby reducing the impact force of the falling object. The degree of freedom of the spring 12 is restricted by the sliding rod 10 to prevent it from deviating when the spring 12 is compressed. This achieves the purpose of adapting to different installation surfaces and protecting against rain, snow and falling objects.

[0025] Please see Figures 1-4In this embodiment, the locking module includes bolts 15, and threaded holes 14 are provided at the upper ends of the four sliders 5. The threaded holes 14 are threadedly connected to the bolts 15. When the bolts 15 rotate, they move up and down inside the threaded holes 14. By setting the bolts 15, they can be rotated in different directions, thereby driving the bolts 15 to move up and down. When the bolts 15 are fully engaged with the guide rod 4, they will clamp the sliders 5 by cooperating with them, thereby fixing the position of the sliders 5. This achieves the purpose of preventing the entire device from sliding through the guide rod 4 after installation. The expansion module includes a lead screw 17, and a groove 16 is provided at the front end of the protective canopy 13. The inner rear right side of the slide groove 16 is rotatably connected to the rear end of the lead screw 17. The rear right side of the protective canopy 13 is rotatably connected to a knob 18, which is connected to the lead screw 17. The knob 18 is used to drive the lead screw 17 to rotate. The lead screw 17 has a sliding component on its outer surface, which includes an extension canopy 19. The extension canopy 19 is threadedly connected to the lead screw 17. When the lead screw 17 rotates, it drives the extension canopy 19 to move. By setting the knob 18, rotating the knob 18 drives the lead screw 17 to rotate. When the lead screw 17 rotates, the slide groove 16 restricts the rotation of the extension canopy 19, thereby driving the extension canopy 19 to move, thus achieving the purpose of expanding the protective area.

[0026] Please see Figures 1-5 In this embodiment, a limiting rod 20 is fixedly installed on the left side of the rear end inside the slide 16. The limiting rod 20 is slidably connected to the expansion shed 19. When the expansion shed 19 moves, it slides along the direction defined by the limiting rod 20. By setting the limiting rod 20, the other side of the expansion shed 19 is restricted in its degree of freedom, thereby further strengthening the rotation restriction of the expansion shed 19, so as to achieve the purpose of assisting the expansion shed 19 to move stably. The heat dissipation module includes a fan 22. Several heat dissipation fins 21 are arranged in a ring on the outer surface of the motor housing 1. The rear end of the motor housing 1 is connected to the front end of the fan 22. By setting the heat dissipation fins 21, the heat dissipation area of ​​the motor is increased. The fan 22 is enlarged to increase airflow and further enhance the motor's heat dissipation capacity, thus achieving the purpose of cooling the motor. The dustproof module includes a protective cover 23, with the rear end of the motor housing 1 connected to the front end of the protective cover 23. The rear end of the protective cover 23 has a mounting slot 24, and a dustproof net 25 is installed inside the mounting slot 24. By setting up the protective cover 23, it is prevented that someone may accidentally touch the running fan 22 and get injured. The mounting slot 24 allows air exchange between the inside of the protective cover 23 and the outside. Finally, the dustproof net 25 prevents dust from entering the inside of the protective cover 23 and causing damage to the fan 22.

[0027] During operation, first adjust the position of the connecting plate 6 so that the connecting groove 7 is above the mounting hole on the mounting surface. Then, use the fixing screw to slide the connecting groove 7 inside to the corresponding mounting surface screw hole for installation. After installation, turn the knob 18 to extend the extension canopy 19 with the cooperation of the limit rod 20 to increase the protection range. When the motor starts, the fan 22 is started synchronously through the external controller to cool the motor. If there is a falling object from a height, the protective canopy 13 will block it to prevent it from directly impacting the motor housing 1. When the protective canopy 13 blocks it, the internal spring 12 will help reduce the impact force.

[0028] Through the above steps, by setting the guide rod 4, the movement path of the slider 5 is limited to follow the guide rod 4. When the slider 5 moves, it will drive the connecting plate 6 connected to it to move together, thereby adjusting the front and back direction of the installation position. Since the connecting groove 7 is a long groove design, the fixing screw can slide inside, thereby adjusting the left and right direction of the installation position. The combination of front and back adjustment and left and right adjustment can adapt to the threaded holes 14 at different positions on the mounting surface. By setting the protective canopy 13, the upper side of the motor housing 1 can be shielded and protected, avoiding the impact of rain and snow or the threat of falling objects when the motor is installed outdoors. When a falling object falls on the protective canopy 13, the protective canopy 13 will move downward and push the telescopic column 11 downward. The downward movement of the telescopic column 11 will compress the spring 12. The spring 12 absorbs and releases the impact energy through compression deformation, reducing the impact force of the falling object. The sliding rod 10 constrains the movement direction of the spring 12 during compression, preventing the spring 12 from shifting during compression. Through the synergistic effect of these structures, the functional requirements of adapting to different mounting surfaces and protecting against rain, snow, and falling objects are finally achieved. This solves the problem of existing motor protective housing structures where the bolt 15 hole positions vary greatly on different mounting surfaces. Traditional structures require the design of a dedicated mounting base model for each mounting surface, significantly increasing the workload of designers. This results in poor installation adaptability, low design efficiency, and when the motor is deployed outdoors, its open top structure is directly exposed to rain, snow, and the threat of falling objects. Rainwater infiltration can easily cause internal short circuits in the motor, while impacts from falling objects may directly damage the motor housing 1 or critical components, leading to significant downtime and maintenance costs.
