Description
Technical Field
[0001] This utility model relates to the field of motor manufacturing and mechanical equipment technology, and in particular to a novel split-type brushless motor. Background Technology
[0002] In fields such as industrial automation and smart homes, brushless motors are widely used due to their advantages such as high efficiency, energy saving, and long lifespan.
[0003] However, traditional brushless motors have two major drawbacks: First, the heat generated during motor operation needs to be dissipated in a timely manner. Existing dustproof structures often have a single filter pore size, which affects heat dissipation efficiency while preventing dust, or makes it difficult to block dust particles of different sizes while ensuring heat dissipation. This allows dust to enter the motor, accelerating component wear and reducing motor performance. Second, the motor installation method is fixed, with poor adaptability, making it difficult to quickly install on different equipment or structures. Moreover, the stability after installation is insufficient, affecting operational reliability. In addition, the assembly and maintenance of split brushless motors are inconvenient due to the connection and disassembly of components, increasing the cost of use and the difficulty of operation. Technological improvements are urgently needed to meet diverse application needs. Utility Model Content

[0027] Please see Figure 1-4 This utility model provides a technical solution:
[0028] A novel split-type brushless motor includes a split-type brushless motor body 1, a rotating shaft 2 fixedly installed on the right end of the split-type brushless motor body 1, a connecting seat 3 fixedly connected to the lower part of the outer surface of the split-type brushless motor body 1, an L-shaped support plate 4 fixedly connected to the lower front and lower rear of the connecting seat 3, an installation device 5 fixedly connected to the right part of the outer surface of the split-type brushless motor body 1, and a dustproof device 6 fixedly connected to the right end of the installation device 5.
[0029] In this embodiment, the dustproof device 6 includes an outer protective box 61. A groove 62 is formed on the upper part of the inner surface of the outer protective box 61. A second positioning hole 63 is fixedly connected to the middle of the right end of the outer protective box 61. Several heat dissipation holes 64 are formed at the right end of the groove 62. Three mounting slots 65 are formed on the inner surface of the outer protective box 61. A snap-fit assembly 66 is slidably connected to the groove 62. A first dustproof net 67, a second dustproof net 68, and a third dustproof net 69 are fixedly connected to the lower end of the snap-fit assembly 66, respectively. The snap-fit assembly 66 includes a mounting plate 661. A sliding plate 662 is fixedly connected to the middle of the upper end of the mounting plate 661. Three fixing slots 663 are formed at the lower end of the mounting plate 661. The width of the sliding plate 662 is adapted to the width of the groove 62. The mounting plate 661 is slidably connected via the sliding plate 662. Within the slide groove 62; the first dustproof mesh 67, the second dustproof mesh 68, and the third dustproof mesh 69 are arranged sequentially along the direction close to the body of the split brushless motor 1, and the mesh diameter of the first dustproof mesh 67 is smaller than that of the second dustproof mesh 68, and the mesh diameter of the second dustproof mesh 68 is smaller than that of the third dustproof mesh 69; the first dustproof mesh 67, the second dustproof mesh 68, and the third dustproof mesh 69 are arranged sequentially along the direction close to the body of the split brushless motor 1, and the mesh diameter of the first dustproof mesh 67 is smaller than that of the second dustproof mesh 68, and the mesh diameter of the second dustproof mesh 68 is smaller than that of the third dustproof mesh 69; a number of heat dissipation holes 64 are distributed in a circular array at the center of the right end of the outer protective box 61, and the spacing between adjacent heat dissipation holes 64 is equal; the diameter of the second positioning hole 63 is larger than the diameter of the rotating shaft 2, and the two are coaxially arranged.
[0030] Through the above scheme: the working principle of the dustproof device 6 is based on the coordinated operation of various components to achieve dustproof and heat dissipation functions. The outer protective box 61 serves as the basic protective structure. The diameter of the second positioning hole 63 at its right end is larger than that of the rotating shaft 2 and is coaxial. It provides rotation space for the rotating shaft 2 while also providing protection. The heat dissipation holes 64 distributed in a ring array ensure that the heat of the motor is evenly dissipated. The snap-fit component 66 slides through the sliding plate 662 and the sliding groove 62, which facilitates installation and disassembly. The fixing groove 663 at the lower end of the mounting plate 661 is snapped into the mounting groove 65 in the outer protective box 61, fixing the first dustproof net 67, the second dustproof net 68, and the third dustproof net 69. The three layers of dustproof nets are arranged in sequence along the direction close to the motor body, and the mesh diameter decreases in sequence to form a graded filtration. Large dust particles are first intercepted by the first dustproof net 67, and smaller particles are then filtered by the second dustproof net 68 and the third dustproof net 69, effectively blocking dust of different particle sizes. At the same time, the design of the dustproof net does not affect the ventilation of the heat dissipation holes 64, ensuring normal heat dissipation of the motor while ensuring the dustproof effect.
[0031] In this embodiment, the mounting device 5 includes a first fixing connecting ring 51 and a second fixing connecting ring 53. The right end of the first fixing connecting ring 51 has several through first positioning holes 52, and the right end of the second fixing connecting ring 53 has several threaded holes 54. Each of the several threaded holes 54 is threaded with a screw 55. The inner surface of the first fixing connecting ring 51 is fixedly connected to the left side of the outer surface of the outer protective box 61, and the inner surface of the second fixing connecting ring 53 is fixedly connected to the right side of the outer surface of the split brushless motor body 1. The several screws 55 are respectively inserted into the corresponding first positioning holes 52 and the corresponding threaded holes 54 and threadedly connected.
[0032] Through the above scheme: the installation device 5 achieves a stable connection between the dustproof device 6 and the motor body through the first fixing connecting ring 51 and the second fixing connecting ring 53. The inner surface of the first fixing connecting ring 51 is connected to the outer protective box 61, and the inner surface of the second fixing connecting ring 53 is in contact with the split brushless motor body 1 to determine the installation position. The first positioning hole 52 corresponds to the threaded hole 54. The screw 55 passes through the first positioning hole 52 in sequence and is threaded to the threaded hole 54. As the screw 55 is tightened, the first fixing connecting ring 51 and the second fixing ring 53 are pressed against each other, tightly fixing the outer protective box 61 to the motor body. This connection method not only ensures a stable connection between the dustproof device 6 and the motor body, but also facilitates disassembly and installation. Components can be flexibly adjusted or replaced according to different usage scenarios, improving the applicability of the device.
[0033] It should be noted that this utility model is a novel split-type brushless motor. During use, firstly, before installing the motor, the second fixing ring 53 is fitted onto the right side of the outer surface of the split-type brushless motor body 1. Next, the inner surface of the first fixing ring 51 is aligned with the left side of the outer surface of the outer protective box 61, ensuring that the first positioning hole 52 corresponds one-to-one with the threaded hole 54 on the second fixing ring 53. Then, screws 55 are passed through the first positioning hole 52 and screwed into the corresponding threaded hole 54. During the tightening of the screws 55, the first fixing ring 53... The fixed connecting ring 51 and the second fixed connecting ring 53 will press against each other, thereby tightly fixing the outer protective box 61 to the split brushless motor body 1, completing the connection work of the installation device 5 to the dustproof device 6 and the motor body. Using the connecting seat 3 and the L-shaped support plate 4 at its lower front and rear, the assembled motor is fixed on the target equipment. The L-shaped support plate 4 can enhance the stability of the motor after installation, ensuring that the motor will not easily shake or shift during operation. When the motor starts to run, the split brushless motor body 1 drives the rotating shaft 2 to rotate, driving the related equipment to operate.
[0034] During operation, the heat generated by the motor is discharged through the heat dissipation holes 64 distributed in a ring array on the outer protective box 61. At this time, dust comes into contact with the motor with the airflow and first comes into contact with the first dust filter 67. Since the mesh diameter of the first dust filter 67 is the smallest, large dust particles will be intercepted by it. Then, smaller dust particles will continue to pass through and be intercepted by the second dust filter 68 with a slightly larger mesh diameter. The remaining finer dust will be blocked by the third dust filter 69. Through this graded filtration method, dust is effectively prevented from entering the motor.
[0035] When cleaning or replacing the dust filter, first locate the sliding plate 662 of the snap-fit assembly 66, which is located in the groove 62 on the upper part of the inner surface of the outer protective box 61. Gently slide the sliding plate 662 along the direction of the groove 62. Because the width of the sliding plate 662 matches the width of the groove 62, the sliding process is relatively smooth. While sliding the sliding plate 662, the mounting plate 661 will move together. The fixing groove 663 at the lower end of the mounting plate 661 will gradually disengage from the mounting groove 65 on the inner surface of the outer protective box 61. When the fixing groove 663 is completely disengaged from the mounting groove 65, the snap-fit assembly 66 can be connected together with the first Dustproof net 67, second dustproof net 68, and third dustproof net 69 are removed from the outer protective box 61 for cleaning, replacement, and other maintenance. After maintenance, the snap-fit assembly 66 with the first dustproof net 67, second dustproof net 68, and third dustproof net 69 is reinstalled back into the outer protective box 61. The slide plate 662 is aligned with the slide groove 62, inserted, and slid along the slide groove 62 so that the fixing groove 663 at the lower end of the mounting plate 661 is snapped into place one by one with the mounting groove 65 in the outer protective box 61, ensuring that the first dustproof net 67, second dustproof net 68, and third dustproof net 69 are firmly installed and the motor can continue to operate normally.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
