Description

Technical Field

[0001] The present invention relates to the technical field of brushless motors, and specifically to a brushless motor for a new energy vehicle heater. Background Art

[0002] A brushless DC motor consists of a motor main body and a driver, and is a typical mechatronic product. Since the brushless DC motor operates in a self-controlled manner, it does not require an additional starting winding on the rotor like a synchronous motor under variable-frequency speed regulation during heavy-load starting, nor does it generate oscillations and loss of synchronization when the load changes suddenly. For the permanent magnets of small and medium-sized brushless DC motors, rare-earth neodymium iron boron materials with high magnetic energy levels are now mostly used. Therefore, the volume of the rare-earth permanent magnet brushless motor is reduced by one frame size compared to a three-phase asynchronous motor of the same capacity.

[0003] Existing brushless motors have systematic defects such as low maintenance efficiency, rapid attenuation of heat dissipation performance, and serious energy consumption redundancy in practical applications: The traditional closed structure requires multiple tools to disassemble a large number of fasteners, significantly extending the time for troubleshooting; The straight-through heat dissipation air duct has low heat exchange efficiency due to insufficient air residence time, and combined with the problem of dust accumulation introduced by open intake, resulting in a continuous increase in the surface thermal resistance of the heat sink; The independent heat dissipation module not only increases energy consumption by relying on an additional power source, but also affects the overall reliability due to the increased complexity of the control system.

[0016] Compared with the prior art, the present invention provides a brushless motor for a new energy vehicle heater, which has the following beneficial effects: 1. For this brushless motor of the new energy vehicle heater, through the provided closing mechanism, the staff only needs to rotate the bolt to complete the disassembly, installation and fixation between the closing cover and the motor body. When a fault occurs in the motor body, the staff can directly repair the internal structure of the motor body by disassembling the convex rod, which is convenient for the staff to maintain and service the motor body in the later stage, and increases the service life of the motor body.

[0017] 2. For this brushless motor of the new energy vehicle heater, through the provided heat dissipation mechanism, the heat dissipation fins are curvedly arranged on the outer circle of the motor body, and cooperate with the sleeve to form a plurality of curved air ducts. When the air flows through the sleeve, it can fully contact the heat dissipation fins for heat exchange, improving the heat exchange efficiency and increasing the heat dissipation effect. At the same time, the staff only needs to rotate the sleeve to complete the disassembly and installation of the sleeve through the threaded cylinder. The detachable sleeve is convenient for the staff to clean the surface of the heat dissipation fins, so that the heat dissipation fins can quickly return to their original state, and the operation is simple and convenient for the staff to use.

[0018] 3. For this brushless motor of the new energy vehicle heater, through the provided heat dissipation mechanism, the fan blades are arranged on the outer circle of the driving shaft and rotate with the outer circle of the driving shaft. When the motor body is in use, as long as the motor body starts to drive the driving shaft to rotate, it can drive the fan blades to rotate and pump the air flow to the right by itself, completing the circulation of the gas in the sleeve, without an additional power source, and at the same time, there is no need to detect the start and stop state of the motor body, and the working process is convenient and easy to use.

[0019] 4. For this brushless motor of the new energy vehicle heater, through the provided air filtering mechanism, the card box is clamped on the outer circle of the air inlet, and the air entering the sleeve is filtered through the filter element, so that the dust in the external air cannot enter the sleeve and contact the heat dissipation fins, so that the heat dissipation fins can always be kept in a relatively clean state. When the motor body is working, the dust cannot adhere to the outer surface of the heat dissipation fins and affect the heat dissipation efficiency of the heat dissipation fins, ensuring the heat conduction efficiency when the heat dissipation fins contact the air, and increasing the heat dissipation efficiency when the device is in use.

[0020] 5. The brushless motor of the new energy vehicle heater is equipped with a gas filtering mechanism. Workers only need to move the paddles on the upper and lower sides inward to drive the clamping blocks to retract into the rotating blocks, controlling the clamping blocks to release the connection with the sleeve frame, enabling workers to quickly disassemble and assemble the card box, facilitating the replacement of the card box by workers and the cleaning of the filter element. Moreover, due to the random angle of the sleeve during the installation process, the angle of the card box after installation is also random. The rotatable rotating block enables the clamping blocks on the upper and lower sides to always be aligned with the sleeve frame inside the card box, facilitating the fixation of the card box by workers.

[0021] 6. The brushless motor of the new energy vehicle heater reconstructs the maintenance process through an integrated quick disassembly and assembly structure. It directly drives the fan blades by the kinetic energy of the drive shaft to form a self-circulating air-cooling system. The innovative curved air duct extends the air flow contact time while integrating a dynamic filtering module, enabling closed-loop control of air flow purification and the cleaning of the radiator surface. Ultimately, it realizes the coordinated improvement of heat dissipation efficiency and maintenance convenience, effectively breaking through the service life limit of traditional motors caused by dust accumulation deterioration and inefficient thermal management under the conditions of high-frequency start-stop and continuous temperature change of the new energy vehicle heater.

At the same time, the staff only needs to rotate the sleeve 2101 to complete the disassembly and assembly of the sleeve 2101 through the threaded cylinder 2103.

Embodiment III

[0033] Refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 8 ,and on the basis of Embodiment I and Embodiment II, it is further obtained that the air filtering mechanism 3 includes an air filtering component 31, a rotating component 32 and a positioning component 33. The air filtering component 31 is arranged on the left side of the motor main body 4. The rotating component 32 is arranged inside the inner ring of the air filtering component 31. The positioning component 33 is arranged inside the rotating component 32.

[0034] The air filtering assembly 31 includes a card box 3101. The card box 3101 is arranged on the left side of the motor main body 4. The card box 3101 is sleeved on the inner ring of the sleeve 2101. The card box 3101 is clamped outside the air inlet 2102. A net plate 3102 is fixedly connected inside the left side of the card box 3101. A filter element 3103 is arranged inside the net plate 3102. The rotating assembly 32 includes a rotating frame 3201.

[0035] Furthermore: The card box 3101 is clamped outside the air inlet 2102. The filter element 3103 filters the air entering the sleeve 2101, so that dust in the external air cannot enter the sleeve 2101 and contact the heat dissipation fins 2105, enabling the heat dissipation fins 2105 to always remain in a relatively clean state. When the motor main body 4 is working, dust cannot adhere to the outer surface of the heat dissipation fins 2105 to affect the heat dissipation efficiency of the heat dissipation fins 2105, ensuring the heat conduction efficiency when the heat dissipation fins 2105 are in contact with air and increasing the heat dissipation efficiency of the device during use.

[0036] During the actual operation process, when this device is in use, the motor main body 4 starts and drives the fan blade 2201 to rotate through the drive shaft 41. The fan blade 2201 rotates to pump the air inside the motor main body 4 out to the right. The air discharge inside the motor main body 4 forms a negative pressure. At this time, external air enters the card box 3101 through the net plate 3102. After being filtered by the net plate 3102, the air enters the sleeve 2101 through the air inlet 2102 and exchanges heat with the heat dissipation fins 2105 through the curved channel formed by the cooperation of the heat dissipation fins 2105 and the sleeve 2101 to complete the cooling of the heat dissipation fins 2105. Then, the heated air enters the motor main body 4 through the ventilation hole 2203 and is pumped out to the right by the rotating fan blade 2201 through the air outlet 2202. At this time, the cooling process of the motor main body 4 is completed; When it is necessary to disassemble the closed cover 1101, the staff first rotates the bolt 1207. The bolt 1207 rotates and moves to the right inside the right side of the motor main body 4 until the bolt 1207 is disengaged from the connection with the motor main body 4. Then the staff directly moves the bolt 1207 to the right. The bolt 1207 moves to the right and is disengaged from the connection with the closed cover 1101. Then the staff rotates the closed cover 1101 to move the convex rod 1201 and the convex block 1202 to move into the plug-in slot 1203 within the first chute 1204. Then the staff can move the closed cover 1101 to the right to complete the disassembly process of the closed cover 1101; When it is necessary to install the sleeve 2101 and the card box 3101, the staff first sleeved the sleeve 2101 on the outer ring of the motor main body 4 until the threaded barrel 2103 contacts the left side of the outer ring of the motor main body 4 and then rotates the sleeve 2101. The rotation of the sleeve 2101 drives the rotation of the threaded barrel 2103. The threaded barrel 2103 rotates and moves to the right on the outer ring of the motor main body 4 until the right side of the sleeve 2101 is completely clamped inside the left side of the sealing ring 2104. At this time, the installation process of the sleeve 2101 is completed; Then the staff places the card box 3101 on the left side of the sleeve 2101 to align the card box 3101 with the air inlet 2102. Then the staff passes a finger through the inner ring of the card box 3101 and toggles the upper and lower paddles 3303 inward. The inward movement of the paddle 3303 drives the clamping block 3304 to move inward through the sliding cylinder 3301. The clamping block 3304 moves inward and retracts into the rotating block 3203. Then the staff moves the card box 3101 to the right to make the card box 3101 clamped in the inner ring of the sleeve 2101. Finally, the staff rotates the position of the rotating block 3203 to align the clamping block 3304 with the sleeve frame 3305 and then releases the control of the two paddles 3303. At this time, the sliding cylinder 3301 drives the clamping block 3304 to move outward under the action of the compression spring 3302. The clamping block 3304 moves outward and is clamped in the sleeve frame 3305. At this time, the installation process of the card box 3101 is completed.
