[0001] The utility model relates to a DC torque motor, belonging to the field of DC motor equipment. Background Art

[0002] A DC torque motor is a special type of DC motor that is specifically designed to produce high torque at low speeds. This type of motor can directly drive the load without the need for an additional reducer or gearbox, making it ideal for applications that require precise control and high torque output.

[0003] In the prior art, when a DC torque motor is used inside a fan drive motor unit, the motor parts are installed inside an open base, and the motor works in a dry environment. Heat can be dissipated through the open base. However, during the heat dissipation process, dust in the air will also enter the base through the heat dissipation holes, resulting in dust accumulation on the surface of the motor winding group, stator and rotor, making it inconvenient to clean the DC torque motor.

[0004] In summary, the utility model provides a DC torque motor to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide a DC torque motor to solve the problem in the above background technology that the open base easily causes dust accumulation during the heat dissipation of the internal parts of the motor, making the DC torque motor difficult to clean later.

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a DC torque motor, comprising a motor body, a motor end cover and a bearing, the motor end cover is fixedly connected to the front of the motor body base by screws, a heat dissipation circular opening is opened between the two sides of the motor end cover, six connecting rods are evenly fixedly connected to the inner wall of the heat dissipation circular opening around the center of the circle, a connecting ring is fixedly connected between the adjacent ends of the six connecting rods, the bearing passes through the two sides of the connecting ring, the output shaft of the motor body passes through the connecting ring through the bearing, a reinforcement rod is fixedly connected to the opposite side of every two connecting rods, a first groove is opened on the side of each connecting rod away from the motor body, and a second groove is opened on the side of each reinforcement rod away from the motor body, and a dust filter assembly is provided on one side of the heat dissipation circular opening and located on the outside of the bearing.

[0007] Furthermore, the centers of the connecting ring and the bearing are located on the same central axis, and the connecting rod and the reinforcing rod are both made of steel.

[0008] Furthermore, the bearing is fixedly connected to the connecting ring, and the connecting ring and the center of the heat dissipation circular opening are located on the same central axis.

[0009] Furthermore, the dust filter assembly includes a dust filter net, a through hole is opened between the two sides of the dust filter net, the dust filter net is sleeved on the outside of the bearing through the through hole and is located on one side of the heat dissipation circular opening, one side of the dust filter net and the inside of each first groove are fixedly connected with a first magnetic strip, and one side of the dust filter net and the inside of each second groove are fixedly connected with a second magnetic strip.

[0010] Furthermore, the first magnetic stripe and the first groove are embedded in each other, and the second magnetic stripe and the second groove are embedded in each other.

[0011] Furthermore, the diameter of the dust filter is equal to the diameter of the heat dissipation circular opening, and one side of the dust filter is in contact with one side of the connecting ring.

[0012] Furthermore, one side of the dust filter screen is in contact with one side of each connecting rod, and one side of the dust filter screen is in contact with one side of the reinforcement rod.

[0013] Beneficial effects of the utility model:

[0014] The dust filter can filter the external air convected at the heat dissipation circular port, ensuring normal ventilation and heat dissipation inside the motor body, while filtering external dust and reducing dust accumulation inside the motor body, effectively protecting the motor body and extending the service life of the DC torque motor. At the same time, the dust filter can be quickly magnetically fixed to the heat dissipation circular port of the motor end cover through the first magnetic strip and the second magnetic strip. It is easy to operate and disassemble, which improves the cleaning convenience of the DC torque motor.

[0015] The dust filter can be directly disassembled by tearing the dust filter. During the tearing process, the first magnetic strip and the second magnetic strip can be deformed along with the dust filter, so it is convenient to separate the magnetic connection between the first magnetic strip and the first groove and the magnetic connection between the second magnetic strip and the second groove one by one.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figure 1-4 The utility model provides a technical solution: a DC torque motor, including a motor body 1, a motor end cover 10 and a bearing 3. The motor end cover 10 is fixedly connected to the front of the motor body 1 base by screws. A heat dissipation circular opening 2 is opened between the two sides of the motor end cover 10. The motor body 1 is a fan drive motor unit, which adopts a DC torque motor. The fan unit is used in an indoor dry environment. The internal winding group, stator and rotor and other parts of the DC torque motor are usually installed inside a casing with holes on the surface. The holes on the surface of the casing are used to dissipate heat for the internal motor winding group and other parts. Six connecting rods 4 are evenly fixedly connected to the inner wall of the heat dissipation circular opening 2 around the center of the circle. A connecting ring 5 is fixedly connected between the adjacent ends of the six connecting rods 4. The bearing 3 runs through the two sides of the connecting ring 5. The output shaft of the motor body 1 passes through the connecting ring 5 through the bearing 3. The opposite sides of every two connecting rods 4 are fixed. A reinforcement rod 6 is connected, and a first groove 7 is provided on the side of each connecting rod 4 away from the motor body 1, and a second groove 8 is provided on the side of each reinforcement rod 6 away from the motor body 1. A dust filter component 9 is provided on one side of the heat dissipation circular opening 2 and located on the outside of the bearing 3. The center of the connecting ring 5 and the bearing 3 are located on the same central axis. The connecting rod 4 and the reinforcement rod 6 are both made of steel material. The bearing 3 is fixedly connected to the connecting ring 5. The center of the connecting ring 5 and the heat dissipation circular opening 2 are located on the same central axis. The heat dissipation circular opening 2 is connected to the inside of the motor body 1 base, so that the inside of the motor body 1 can be directly ventilated and cooled from the motor end cover 10, which effectively improves the heat dissipation efficiency of the DC torque motor, and the external air convected by the heat dissipation circular opening 2 can be filtered through the dust filter component 9 to avoid dust accumulation in the internal parts of the motor body 1 without affecting the normal ventilation and heat dissipation of the heat dissipation circular opening 2.

[0024] See also Figure 2-4The dust filter assembly 9 includes a dust filter 91, and a through hole 92 is opened between the two sides of the dust filter 91. The dust filter 91 is sleeved on the outside of the bearing 3 through the through hole 92 and is located on one side of the heat dissipation circular port 2. A first magnetic strip 93 is fixedly connected to one side of the dust filter 91 and is located inside each first groove 7. A second magnetic strip 94 is fixedly connected to one side of the dust filter 91 and is located inside each second groove 8. The first magnetic strip 93 and the first groove 7 are mutually embedded, and the second magnetic strip 94 and the second groove 8 are mutually embedded. The diameter of the dust filter 91 is equal to the diameter of the heat dissipation circular port 2. One side of the dust filter 91 is in contact with one side of the connecting ring 5, one side of the dust filter 91 is in contact with one side of each connecting rod 4, and one side of the dust filter 91 is in contact with one side of the reinforcement rod 6. The first magnetic strip 93 and the second magnetic strip 94 are both made of rubber magnets. Rubber magnets are also called soft magnets or magnetic rubbers. They are a flexible magnetic material made by mixing rubber and magnetic powder (such as ferrite powder). It has a soft , bendable, and easy to process, while maintaining magnetism and being adsorbed on the surface of iron or steel. When the first magnetic strip 93 is embedded in the front face of the connecting rod 4 through the first groove 7, it can be magnetically fixed to the connecting rod 4 made of steel material. When the second magnetic strip 94 is embedded in the second groove 8 on the front face of the reinforcing rod 6 through the second groove 8, it can be magnetically fixed to the reinforcing rod 6 made of steel material, so that the dust filter 91 can be quickly magnetically fixed to the heat dissipation circular port 2 of the motor end cover 10 through the first magnetic strip 93 and the second magnetic strip 94, and the dust filter 91 can be directly torn, disassembled and cleaned. During the tearing process of the dust filter 91, the first magnetic strip 93 and the second magnetic strip 94 can be deformed along with the dust filter 91, so that the magnetic connection between the first magnetic strip 93 and the first groove 7 and the magnetic connection between the second magnetic strip 94 and the second groove 8 can be separated one by one. The dust filter 91 can be quickly disassembled, and the weight of the first magnetic strip 93 and the second magnetic strip 94 is lighter than that of the magnet, so that the overall weight of the dust filter assembly 9 is lighter.

[0025] Specific implementation method: The heat dissipation circular opening 2 is connected to the inside of the motor body 1, so that the inside of the motor body 1 can be directly ventilated and cooled from the motor end cover 10, effectively improving the heat dissipation efficiency of the DC torque motor.

[0026] When the first magnetic strip 93 is embedded in the front face of the connecting rod 4 through the first groove 7, it can be magnetically fixed to the connecting rod 4 made of steel material. When the second magnetic strip 94 is embedded in the second groove 8 on the front face of the reinforcing rod 6 through the second groove 8, it can be magnetically fixed to the reinforcing rod 6 made of steel material, so that the dust filter 91 can be quickly magnetically fixed to the heat dissipation circular port 2 of the motor end cover 10 through the first magnetic strip 93 and the second magnetic strip 94. The dust filter 91 can filter the external air convected at the heat dissipation circular port 2, thereby ensuring normal ventilation and heat dissipation inside the motor body 1 and filtering external dust, reducing dust accumulation inside the motor body 1, effectively protecting the motor body 1, and extending the service life of the DC torque motor.

[0027] The dust filter net 91 can be directly disassembled by tearing it. During the tearing process, the first magnetic strip 93 and the second magnetic strip 94 can be deformed along with the dust filter net 91, so that the magnetic connection between the first magnetic strip 93 and the first groove 7 and the magnetic connection between the second magnetic strip 94 and the second groove 8 can be separated one by one. The dust filter net 91 can be quickly disassembled and cleaned for recycling. The weight of the first magnetic strip 93 and the second magnetic strip 94 is lighter than that of the magnet, so that the overall weight of the dust filter assembly 9 is lighter, and the disassembly is more convenient and labor-saving.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
