Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to an energy-saving motor for a high-efficiency heat dissipation hub. Background Art

[0002] The energy-saving motor for efficient heat dissipation hub is a motor designed to improve the heat dissipation efficiency and energy efficiency of the motor. This motor can effectively reduce energy waste, improve work efficiency and long-term stability. At the same time, its simplified structural design reduces production and maintenance costs, and is particularly suitable for high-load operation application scenarios, such as electric vehicle hub motors and industrial equipment.

[0003] According to the Chinese patent authorization announcement: CN113675997A, an energy-saving motor disclosed includes a base, a working chamber is provided inside the base, and a bearing channel is connected between the two side walls of the working chamber and the two side end faces of the base; the present invention uses a piston that can move back and forth to realize the output of hot air flow inside the working chamber, accelerate the circulation of air flow inside the working chamber, and improve the heat dissipation effect of the motor. When the output shaft stops rotating, the hot air flow accumulates inside the piston chamber to heat up the pressurized agent, thereby realizing the release of high-pressure external force, thereby converting power into torque and using the power component to increase the output shaft distance, thereby relieving the occurrence of the output shaft stuck due to a sudden increase in load; the invention uses a hydraulic torque converter to connect the rotating shaft with the output shaft for power, solves the problem of the rotating shaft stopping due to excessive external load, and then can use the built-in fan to continuously dissipate heat for the stator winding and coil, thereby improving the efficiency of power utilization, but the energy-saving motor still has some problems when in use: This energy-saving motor uses a piston to promote the circulation of air inside the working chamber. This method may improve the heat dissipation efficiency under certain conditions, but relying on the reciprocating motion of the piston to achieve the output of hot air flow may cause the continuity of the heat dissipation process to be unstable. In addition, the complexity of the piston structure may cause mechanical wear and noise problems, which may affect the reliability and stability of the equipment in long-term use.

[0004] The piston design in this patent requires multiple gas channels and piston chambers, as well as supporting structures such as a boost agent and a torque converter. The presence of these components may make the entire motor structure more complicated, increasing production costs and maintenance difficulties.

[0005] The high-pressure external force is released by heating the pressurized agent through the hot air flow accumulated inside the piston chamber. This heat management method is relatively indirect and may lead to insufficient accuracy of heat management and failure to quickly respond to changes in the internal temperature of the motor.

[0006] In the event of a sudden increase in load, the energy-saving motor relies on the torque converter and boost agent to release the output shaft from a stuck state, which may have a certain lag. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides an energy-saving electric motor for an efficient heat dissipation hub, which solves the problem that the heat dissipation structure is relatively complex and relies on multiple components to achieve thermal management, which may lead to problems in heat dissipation efficiency and reliability.

[0019] 2. In the present invention, through the installation mechanism, when the motor body needs to be installed, the user first places the motor body on the locking plate, and then gently pushes the motor body, and the two locking rods on the inner side of the locking plate are automatically inserted into the locking hole. As the locking plate moves, the rack 2 is driven, thereby driving the gear to rotate. During the rotation of the gear, the two racks 1 move to both sides respectively, thereby pushing the two clamping plates to move. The two clamping plates will tightly clamp the two sides of the motor body to ensure its stability. Finally, the spring rod is inserted into the bottom of the motor body to firmly lock the motor body, which not only makes the installation of the motor body without the aid of additional tools, but also significantly reduces the installation time and improves the operating efficiency.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1 - Figure 7 The present invention provides two technical solutions, which specifically include the following embodiments: Embodiment 1

[0024] An energy-saving motor for a high-efficiency heat dissipation hub comprises a motor body 1, a heat dissipation mechanism 2 is arranged inside the motor body 1, the heat dissipation mechanism 2 comprises a temperature control switch 201, a heat dissipation fan 202, a stator 203, an outer rotor 204, heat dissipation fins 205, an L-shaped heat pipe 206, a heat dissipation hole 1 6 and a heat dissipation hole 2 4, a stator 203 is arranged inside the motor body 1, an outer rotor 204 is arranged outside the stator 203, an output shaft 5 is fixedly connected to one side wall of the outer rotor 204, a plurality of heat dissipation fins 205 are fixedly connected to the outer wall of the outer rotor 204, a plurality of L-shaped heat pipes 206 are arranged outside the outer rotor 204, a temperature control switch 201 is arranged on the top of the motor body 1, and a heat dissipation fan 202, a stator 203 ... outer rotor 204, and a plurality of heat dissipation fins 205 are fixedly connected to the outer wall of the outer rotor 204. The bottom end of 01 is fixedly connected to the top of the motor body 1, the inner wall of the motor body 1 is rotatably connected with a cooling fan 202, the outer rotor 204 is rotatably connected to the inner wall of the motor body 1, one end of the output shaft 5 passes through a side wall of the motor body 1, the middle part of the output shaft 5 is rotatably connected to a side wall of the motor body 1, the evaporation ends of multiple L-shaped heat pipes 206 are fixedly connected to the outer wall of the outer rotor 204, the condensation ends of multiple L-shaped heat pipes 206 are respectively fixedly passed through multiple cooling fins 205, the detection end of the temperature control switch 201 is set on the inner wall of the top of the motor body 1, the cooling fan 202 is electrically connected to the temperature control switch 201, and the specific model of the temperature control switch 201 is Honeywell T775 Series, the temperature threshold set by the temperature control switch 201 is 45 degrees. When the temperature control switch 201 detects that the temperature inside the motor body 1 is higher than 45 degrees, the cooling fan 202 will be started to speed up the air flow inside the motor body 1. When the temperature inside the motor body 1 is lower than 45 degrees, the temperature control switch 201 will turn off the cooling fan 202, thereby achieving the purpose of energy saving. A plurality of cooling holes 16 are opened on one side wall of the motor body 1, and a plurality of cooling holes 24 are opened on the back of the motor body 1. The cooling holes 16 and the cooling holes 24 are designed as cooling fans. When 202 is in operation, air inlet and outlet channels are provided, thereby enhancing the circulation of internal air and accelerating the heat dissipation effect. It should be noted that inside the motor body 1, the stator 203 is fixedly installed and is responsible for generating an electromagnetic field to drive the rotation of the outer rotor 204. The outer rotor 204 is installed on the outside of the stator 203 and is connected to the external load through the output shaft 5 to achieve power transmission. A plurality of heat dissipation fins 205 are fixedly installed on the outer wall of the outer rotor 204. These heat dissipation fins 205 increase the flow speed of the internal air through the rotation of the outer rotor 204, thereby improving the heat dissipation effect.

[0025] When the user starts the motor body 1, the stator 203 starts to work, causing the outer rotor 204 to rotate. The rotation of the outer rotor 204 not only generates driving force, but also drives the heat dissipation fins 205 installed on the inner side thereof to rotate around the inner wall of the motor body 1. This design increases the flow speed of the air inside the motor and effectively enhances the convection heat dissipation effect of the internal air. During the operation of the motor body 1, the outer rotor 204 generates a large amount of heat due to the current passing through the coil. In order to effectively manage this heat, a plurality of L-shaped heat pipes 206 are designed. The evaporation end of the heat pipe fits tightly against the surface of the outer rotor 204. When the outer rotor 204 generates heat, the heat is quickly transferred to the evaporation end of these heat pipes. The working fluid in the heat pipe evaporates due to the heat and transfers the heat to the condensation end through capillary action and gravity. The condensation end is tightly connected to a plurality of heat dissipation fins 205. The heat is dissipated to the external environment through the fins here, ensuring efficient heat dissipation of the motor body 1. In addition, to further control the temperature inside the motor body 1, when the temperature control switch 201 detects that the internal temperature of the motor exceeds the set temperature threshold, the heat dissipation fan 202 will be automatically started. The operation of the heat dissipation fan 202 cooperates with the heat dissipation holes 1 6 and 2 4 on the outer shell of the motor body 1, significantly accelerating the flow of air inside the motor body 1, accelerating the discharge of heat, and realizing active heat dissipation. This multiple heat dissipation design ensures that the motor body 1 remains within a safe operating temperature range when operating efficiently, thereby extending the service life of the motor body 1 and improving the overall performance and reliability.

[0026] On the basis of the first embodiment, a mounting mechanism 3 is provided at the bottom of the motor body 1, and the mounting mechanism 3 includes an unlocking plate 302, a locking hole 303, an unlocking groove 305, a mounting plate 304, a locking rod 307, a locking plate 308, a gear 311, a rack 1 309, a storage groove 313, a limiting rod 314 and a rack 2 310. An unlocking groove 305 is provided on one side wall of the mounting plate 304, and the inner wall of the unlocking groove 305 is vertically slidably connected to the unlocking plate 302, and the top of the unlocking plate 302 is fixedly connected to the spring rod 306. A groove adapted to the spring rod 306 is provided at the bottom end of the motor body 1, and the cooperation between the locking rod 307 and the locking hole 303 and the cooperation between the spring rod 306 and the groove can increase the motor body. 1, the top of the mounting plate 304 is slidably connected to two clamping plates 301, the top of the mounting plate 304 is rotatably connected to a gear 311, both sides of the gear 311 are meshed with a rack 1 309, a locking plate 308 is provided on the top of the mounting plate 304, the inner side of the locking plate 308 is fixedly connected to two locking rods 307, a mounting groove 312 is provided on the top of the locking plate 308, and a rack 2 310 is fixedly connected to one side of the inner wall of the mounting groove 312, and two locking holes 303 are provided on the other side wall of the motor body 1, and the two locking rods 307 are respectively inserted into the inside of the two locking holes 303, the top of the spring rod 306 passes through the mounting plate 304, and is vertically slidably connected to the mounting plate 304, and the two clamping plates The top of each of the clamping plates 301 is provided with a storage slot 313. The clamping plate 301 can be translated along the top of the mounting plate 304 by sliding connection, and is used to fix the front and back of the motor body 1. The storage slots 313 provided on the top of these clamping plates 301 match the rack 1 309. The bottom end of the rack 1 309 is slidably connected to the top of the mounting plate 304, and the other end is fixedly connected to the inner side of the clamping plate 301, thereby ensuring that the clamping plate 301 can remain stable during movement. The sizes of the two racks 1 309 match the sizes of the two storage slots 313. The inner sides of the two clamping plates 301 are respectively fitted to the front and back of the motor body 1. The tops of the two clamping plates 301 are slidably connected to the limit rod 314. The limit rod 314 is fixedly connected to the inner side of the clamping plate 301. The rod 314 is designed to prevent the clamping plate 301 from exceeding a predetermined range when moving on the mounting plate 304. The bottom ends of the two limit rods 314 are fixedly connected to the top of the mounting plate 304, and the top ends are slidably connected to the top of the clamping plate 301 to ensure that the clamping plate 301 will not deviate or get stuck during movement. The bottom ends of the two limit rods 314 are fixedly connected to the top of the mounting plate 304, and the bottom ends of the two racks 1 309 are slidably connected to the top of the mounting plate 304. One end of the two racks 1 309 is fixedly connected to the inner side of the two clamping plates 301, respectively. The inner side of the rack 2 310 is meshed with one side of the gear 311, and the bottom end of the locking plate 308 is slidably connected to the top of the mounting plate 304.

[0027] When the motor body 1 needs to be installed, the user first places it on the locking plate 308. The pushing force of the motor body 1 will cause the two locking rods 307 on the inner side of the locking plate 308 to automatically insert into the locking hole 303 at the bottom of the motor body 1 to ensure initial positioning and fixation. As the motor body 1 continues to be pushed, the locking plate 308 will move, driving the rack 2 310 connected to it to move together. The movement of the rack 2 310 will further drive the gear 311 to rotate. The rotation of the gear 311 is the core of the entire locking and fixing process. While the gear 311 rotates, the two racks 1 309 connected to the gear 311 will be driven to move in opposite directions. This action will drive the two clamping plates 301 connected to the rack 1 309 to move. The moving direction of 301 is consistent with the moving direction of rack 309. They move inward respectively to clamp the two sides of the motor body 1, thereby providing lateral support to prevent the motor body 1 from shaking or shifting left and right during the installation process. While completing the lateral clamping, the spring rod 306 will automatically insert into the bottom end of the motor body 1. The function of the spring rod 306 is to provide additional fixing force to ensure that the motor body 1 will not loosen or fall off due to external force or vibration. This multi-level fixing design not only improves the stability and safety of the installation process, but also avoids the need for users to use additional tools for installation, significantly reduces the installation time, makes the entire operation process more efficient and quick, improves the installation efficiency of the motor body 1, and ensures the safety of the use of the motor body 1.
