Description

Technical Field

[0001] This application relates to the field of electric motors, and more particularly to a vibration-damping and low-noise electric motor. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is widely used in industries such as industry, agriculture, commerce, and construction.

[0003] For example, utility model patent CN203071695U discloses an electric motor, including a housing, with a front cover and a rear cover at both ends of the housing. The stator and rotor are installed inside the housing. The front cover has a first screw hole, and the rear cover has a second screw hole. A bolt passes through the first screw hole and the second screw hole. The front cover has a first mounting groove around the first screw hole, and a first sealing ring is installed in the first mounting groove. The rear cover has a second mounting groove around the second screw hole, and a second sealing ring is installed in the second mounting groove. This electric motor has a simple manufacturing process, low production cost, and higher production efficiency.

[0004] The motor described above will vibrate during operation, which will affect the stability of the internal parts and may even damage them. Long-term vibration will shorten the motor's lifespan. At the same time, vibration will cause noise, which will affect the work and life of people in the surrounding area. This needs to be improved. Summary of the Invention

[0005] In order to improve the vibration damping and noise reduction performance of the motor, this application provides a vibration damping motor.

[0006] The vibration-damping and low-noise motor provided in this application adopts the following technical solution:

[0007] A vibration-damping and low-noise motor includes a motor body and a base located below the motor body. A slide rod is mounted on the motor body and is vertically connected to the base. An elastic element is provided between the base and the motor body. A contact rod is rotatably connected to the base. A second elastic element is mounted on the rotating shaft of the contact rod, and the second elastic element abuts against the base, causing the contact rod to abut against the lower end of the slide rod. A swing plate is rotatably connected to the base and located on one side of the motor body. A transmission assembly is also provided on the base, and the contact rod drives the swing plate to swing back and forth via the transmission assembly.

[0008] By adopting the above technical solution, when the motor body vibrates, the elastic force of the first elastic element buffers and dampens the motor body, reducing the impact of vibration on the motor body and helping to extend the service life of the motor body. At the same time, the second elastic element is pressed against the lower end of the slide rod through the abutment rod, sharing the pressure on the first elastic element and buffering the motor body together, inhibiting elastic fatigue of the first elastic element, which helps to extend the service life of the first elastic element and improve the durability of the vibration damping performance of the motor body. The vibration damping performance of the motor body is improved from both direct and indirect aspects.

[0009] During the vibration of the motor body, the sliding rod drives the abutment rod to reciprocate and rotate, causing the abutment rod to drive the swing plate to swing back and forth through the transmission component, fanning the surface of the motor body, accelerating the airflow on the surface of the motor body, promoting heat dissipation of the motor, reducing the possibility of internal parts of the motor body expanding due to excessive temperature, causing friction and noise between parts, which helps to reduce the noise generated by the operation of the motor body and improves the noise reduction performance of the motor body.

[0010] Preferably, the transmission assembly includes a fixed rod and an elastic element three disposed on the base, and a transmission block that slides and rises on the fixed rod. The fixed rod passes through the abutment rod, and the transmission block is located on the side of the swing plate away from the motor body. The elastic element two pulls the transmission block so that the transmission block abuts against the upper end face of the abutment rod. The transmission block is provided with a corrugated groove along the sliding direction of the transmission block. The swing plate includes a plate body rotatably connected to the base and a protrusion provided on the plate body. The protrusion extends into the corrugated groove.

[0011] By adopting the above technical solution, when the abutment rod reciprocates, the abutment rod drives the transmission block to reciprocate up and down, causing the protrusion to slide along the inner wall of the corrugated groove, thereby driving the plate to swing back and forth, making it more convenient to drive the plate to swing back and forth.

[0012] Preferably, the base is provided with a through rod, and a receiving block slides up and down on the through rod. The receiving block has a receiving cavity. A piston is provided on the through rod and is located in the receiving cavity. A connecting pipe is provided between the receiving block and the motor body, and the connecting pipe connects the receiving cavity and the interior of the motor body. The receiving block has an air inlet that communicates with the receiving cavity. The connection between the connecting pipe and the receiving block and the air inlet are located on the same side of the piston. The receiving block is provided with a first one-way valve, which is located in the air inlet and allows one-way flow from the outside of the receiving block to the receiving cavity. The connecting pipe is provided with a second one-way valve, which allows one-way flow from the receiving cavity to the interior of the motor body. The base is provided with a linkage, and the sliding rod drives the receiving block to reciprocate up and down through the linkage.

[0013] By adopting the above technical solution, when the motor body vibrates, the motor body drives the slide rod to move up and down repeatedly, and the slide rod drives the receiving block to move up and down repeatedly, thereby continuously drawing in the cooler air outside the receiving block into the receiving cavity, and sending the air from the receiving cavity into the motor body. This allows the hot air inside the motor body to leak through the gaps on the motor body, realizing the exchange between the hot air inside the motor body and the cold air outside the motor body, promoting heat dissipation of the motor body, suppressing the rise in internal temperature of the motor body, and helping to reduce the noise generated by the friction of internal parts of the motor body, thus achieving a better noise reduction effect.

[0014] Preferably, the linkage is rotatably connected to the base, the slide rod is provided with a toothed surface one, and the receiving block is provided with a toothed surface two. The toothed surface one and the toothed surface two are respectively located on opposite sides of the linkage and mesh with the linkage.

[0015] By adopting the above technical solution, when the slide bar moves, the slider drives the linkage to rotate through the cooperation of tooth surface one and the linkage component. The linkage component drives the receiving block to move through the cooperation of tooth surface two, making it easier to move the receiving block and reducing the transmission wear between the receiving block, the slide bar and the linkage component.

[0016] Preferably, the receiving block is provided with a filter screen, which is located on the side of the one-way valve away from the receiving cavity, and the filter screen is located in the fan area of ​​the plate.

[0017] By adopting the above technical solution and setting up a filter screen, when the air outside the receiving block enters the receiving cavity through the air inlet, the air is filtered, reducing the possibility of air carrying impurities into the air inlet and thus blocking the one-way valve. This helps the one-way valve to stably perform its one-way conduction function. When the air outside the motor body exchanges with the air inside the motor body, the swing plate swings back and forth continuously, and the resulting wind force blows away some of the dust or impurities remaining on the surface of the filter screen, reducing the possibility of the filter screen being blocked and helping the filter screen to stably perform its filtering function. The sliding rod drives the receiving block to move back and forth continuously, making the adhesion of dust or impurities remaining on the filter screen smaller and the connection looser, making it easier to be blown away by the wind force generated by the swing of the plate.

[0018] Preferably, the base includes a seat and a mounting plate disposed on the seat. The abutment rod is rotatably connected to the seat. The seat has a mounting groove for the mounting plate to be inserted into. The mounting plate has a groove for the elastic element to be inserted into. The seat has a through hole for the elastic element to pass through. The seat has a positioning component for positioning the mounting plate. The hinge shaft of the abutment rod has a slot. A positioning element is slidably connected to the seat. The positioning element is inserted into the slot and positions the abutment rod.

[0019] By adopting the above technical solution, when the elastic element 1 is damaged, the positioning component is inserted into the slot to position the abutment rod. The abutment rod positions the motor body through the sliding rod. Then, the positioning state of the mounting plate is released, and the mounting plate is moved to disengage from the mounting slot. The damaged elastic element 1 can then be removed from the groove for replacement. After replacement, the mounting plate is inserted into the mounting slot, and the mounting plate is positioned by the positioning component. The replacement of the elastic element 1 can be completed without disassembling the entire base, making the replacement of the elastic element 1 more convenient.

[0020] Preferably, the positioning element includes a locking block slidably connected to the base and a connecting block rotatably connected to the locking block, the locking groove for the locking block to engage, and the connecting block and the base being threadedly connected.

[0021] By adopting the above technical solution, a locking block and a connecting block are set. The locking block is moved by the threaded engagement between the connecting block and the base. After the locking block moves to the corresponding position, the connecting block is released, which can realize the positioning of the locking block and make positioning the locking block more convenient.

[0022] Preferably, the positioning component includes a fixed block and an elastic element four disposed on the base, and a positioning block slidably connected to the fixed block. The mounting plate has a through hole for the fixed block to pass through. The positioning block slides out of or close to the fixed block. The elastic element four is located on the side of the positioning block close to the fixed block. When the elastic element four is not under force, the positioning block abuts against the side of the mounting plate away from the motor body.

[0023] By adopting the above technical solution, a fixed block, an elastic element four, and a positioning block are set. When it is necessary to remove the mounting plate, press the positioning block to make the positioning block detach from the mounting plate, and then move the mounting plate away from the base to remove the mounting plate. After replacing the elastic element one, the mounting plate is inserted into the mounting groove. Then, the positioning block is released. Under the action of the elastic element four, the positioning block extends out of the fixed block and abuts against the side of the mounting plate away from the motor body, thus completing the installation of the mounting plate, making the installation and removal of the mounting plate more convenient.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By using elastic component one and elastic component two, the vibration damping performance of the motor body is improved from both direct and indirect aspects, reducing the impact of vibration on the motor body and helping to extend the service life of the motor body. The cooperation between the slide rod, the abutment rod and the transmission component drives the swing plate to swing back and forth, accelerating the airflow on the surface of the motor body, promoting heat dissipation, reducing the expansion of internal parts of the motor body due to excessive temperature, and reducing the friction between parts that generates noise, thus improving the noise reduction performance of the motor body.

[0026] 2. When the motor body vibrates, it drives the housing block to move up and down repeatedly, realizing the exchange of hot air inside the motor body and cold air outside the motor body, suppressing the rise of the internal temperature of the motor body, which helps to reduce the noise generated by the friction of the internal parts of the motor body, achieving a better noise reduction effect, and reducing the adhesion of dust or debris remaining on the filter screen, making it easier for the wind force generated by the swing plate to blow away the dust or debris remaining on the surface of the filter screen, reducing the chance of the filter screen being blocked.

[0027] 3. When the elastic element is damaged, the positioning part is inserted into the slot to position the abutment rod, which can support the motor body. Then the damaged elastic element can be replaced without disassembling the entire base, making the replacement of the elastic element more convenient. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0037] This application discloses a vibration-damping, low-noise motor. See also... Figure 1 The vibration-damping and low-noise motor includes a motor body 1 and a base 2. The motor body 1 is located above the base 2. Two slide rods 11 are fixed on the lower end face of the motor body 1. The two slide rods 11 are arranged opposite each other. Both slide rods 11 pass through the base 2 and slide up and down on the base 2.

[0038] See Figure 1 The base 2 includes a seat body 21 and a mounting plate 22. The seat body 21 includes a connecting portion 211, two transition portions 212, and two support portions 213. The two transition portions 212 are located on opposite sides of the connecting portion 211 and are fixedly connected to the connecting portion 211. The positions of the two transition portions 212 correspond one-to-one with the positions of the two slide rods 11. Each transition portion 212 is located on the side of the corresponding slide rod 11 away from the other slide rod 11, and the two transition portions 212 are separated from each other in a direction away from the motor body 1. The positions of the two support portions 213 correspond one-to-one with the positions of the two transition portions 212. Each support portion 213 is located on the side of the corresponding transition portion 212 away from the connecting portion 211 and is fixedly connected to the corresponding transition portion 212. In this embodiment, the connecting portion 211, the transition portion 212, and the support portion 213 are integrally formed.

[0039] See Figure 2 and Figure 3The lower end face of the connecting part 211 is provided with a mounting groove 2111, into which the mounting plate 22 is inserted. A plurality of elastic members 18 are provided on the connecting part 211, and the elastic members 18 are located between the motor body 1 and the mounting plate 22. A plurality of through holes 2112 are provided on the end face of the connecting part 211 near the motor body 1, and the through holes 2112 are vertically inserted through the connecting part 211. The number and position of the through holes 2112 correspond one-to-one with the number and position of the elastic members 18. The through holes 2112 are provided for the corresponding elastic members 18 to pass through. A plurality of grooves 221 are provided on the end face of the mounting plate 22 near the motor body 1. The number and position of the grooves 221 correspond one-to-one with the number and position of the through holes 2112. Each groove 221 is connected to the corresponding through hole 2112, and the groove 221 is provided for the corresponding elastic member 18 to be inserted. The opposite ends of the elastic member 18 are respectively pressed against the inner wall of the bottom of the groove of the motor body 1 and the corresponding groove 221.

[0040] See Figure 3 The connecting part 211 is provided with a positioning component 3, which is used to position the mounting plate 22. The positioning component 3 includes a fixing block 31, a positioning block 32 and an elastic element 33. The fixing block 31 is located in the mounting groove 2111 and is fixedly connected to the connecting part 211. The mounting plate 22 is provided with a through hole 222 for the fixing block 31 to pass through.

[0041] See Figure 2 and Figure 3 Two sliding grooves 311 are provided on the outer side wall of the fixing block 31. The two sliding grooves 311 are located on opposite sides of the fixing block 31. The number and position of the positioning blocks 32 correspond one-to-one with the number and position of the sliding grooves 311. Each positioning block 32 is slidably connected in the corresponding sliding groove 311, and the positioning block 32 slides out or close to the fixing block 31. When the mounting plate 22 is located in the mounting groove 2111, the positioning block 32 is located on the side of the mounting plate 22 away from the motor body 1 and abuts against the mounting plate 22.

[0042] See Figure 2 and Figure 3 Each positioning block 32 has an inclined surface 321 formed on it. The inclined surface 321 is located on the side of the positioning block 32 away from the motor body 1 and at the end of the positioning block 32 away from the fixing block 31. The inclined surface 321 is inclined toward the motor body 1 in the direction away from the fixing block 31.

[0043] See Figure 3The number and position of the elastic element 33 correspond one-to-one with the number and position of the slide groove 311. The elastic element 33 is located within the corresponding slide groove 311 and on the side of the positioning block 32 near the bottom of the slide groove 311. The opposite ends of the elastic element 33 are fixedly connected to the inner wall of the bottom of the corresponding slide groove 311 and the positioning block 32, respectively. When the elastic element 33 is not subjected to external force, the positioning block 32 extends out of the fixing block 31. When the corresponding elastic element 33 is pressed towards the bottom of the slide groove 311, the opposite ends of the elastic element 33 abut against the inner wall of the bottom of the corresponding slide groove 311 and the positioning block 32, causing the positioning block 32 to tend to extend out of the fixing block 31. In this embodiment, the elastic element 33 is a spring.

[0044] In actual use, when it is necessary to remove the mounting plate 22 from the connecting part 211, press the positioning block 32 towards the fixing block 31 to make the positioning block 32 disengage from the mounting plate 22, and then move the mounting plate 22 away from the connecting part 211 to remove the mounting plate 22.

[0045] When it is necessary to install the mounting plate 22 onto the connecting part 211, the mounting plate 22 is inserted into the mounting groove 2111. The mounting plate 22 abuts against the inclined surface 321, pushing the positioning block 32 to slide closer to the fixing block 31 until the mounting plate 22 is located in the mounting groove 2111. At this time, the positioning block 32 is located on the side of the mounting plate 22 away from the motor body 1. Under the action of the elastic element 33, the positioning block 32 extends out of the fixing block 31 and abuts against the side of the mounting plate 22 away from the motor body 1 to position the mounting plate 22, thus completing the installation of the mounting plate 22.

[0046] See Figure 4 and Figure 5 Each transition section 212 is rotatably connected to an abutment rod 4. The abutment rod 4 is located below the corresponding slide rod 11, and its opposite ends are located on opposite sides of the transition section 212. The rotation axis of the abutment rod 4 is horizontally arranged. An elastic element 41 is installed on the rotation axis of the abutment rod 4. The opposite ends of the elastic element 41 abut against the transition section 212 and the rotation axis of the abutment rod 4, respectively, so that the abutment rod 4 abuts against the lower end of the corresponding slide rod 11. In this embodiment, the elastic element 41 is a torsion spring.

[0047] See Figure 2 and Figure 6 The upper end face of the abutment rod 4 is provided with a clearance hole 42, and the clearance hole 42 and the slide rod 11 are located on opposite sides of the rotation axis of the abutment rod 4.

[0048] See Figure 5Each abutment rod 4 has a slot 5 at one end of its rotating shaft. The slot 5 is a rectangular groove. Each transition part 212 has an insert 2121 on its outer side wall. The position of the insert 2121 corresponds to the position of the slot 5, and the insert 2121 and the slot 5 are connected. Each transition part 212 is slidably connected to a positioning member 6. The positioning member 6 includes a locking block 61 and a connecting block 62. The locking block 61 is located in the insert 2121 and passes through the transition part 212 and is slidably connected to the transition part 212 in a direction close to the slot 5. The sliding direction of the locking block 61 is parallel to the rotation axis of the abutment rod 4. The slot 5 is for the locking block 61 to be inserted. When the locking block 61 is inserted into the slot 5, the locking block 61 fits against the inner wall of the slot 5 and positions the abutment rod 4.

[0049] See Figure 5 The connecting block 62 is located on the side of the locking block 61 away from the slot 5 and is rotatably connected to the locking block 61. The rotation axes of the connecting block 62 and the locking block 61 are parallel to the sliding direction of the locking block 61. The connecting block 62 is threadedly connected to the groove 2121. The locking block 61 is slidably connected to the transition part 212 through the threaded connection between the connecting block 62 and the transition part 212.

[0050] In practical use, when the elastic element 18 is damaged, the connecting block 62 is twisted, causing the locking block 61 to slide and lock into the slot 5 to position the abutment rod 4. The abutment rod 4 is positioned by pressing against the sliding rod 11. Then, the mounting plate 22 is removed from the connecting part 211. The mounting plate 22 moves down under gravity and is limited by the abutment rod 4 against the mounting plate 22. The sliding rod 11 is also against the mounting plate 22 to restrict the horizontal movement of the mounting plate 22, so that the groove 221 and the through hole 2112 are aligned one by one. At this time, the mounting plate 22 and the connecting part 211 are separated, so that the damaged elastic element 18 in the groove 221 can be taken out and replaced. Then, the intact elastic element 18 is placed in the groove 221, and the mounting plate 22 is locked into the mounting slot 2111 for positioning. The replacement and installation of the elastic element 18 can be completed without disassembling the entire base 2.

[0051] See Figure 2 and Figure 6 Each support 213 is fixed with a vertical rod 7. The vertical rod 7 is located on the side of the support 213 closer to the motor body 1 and passes through the abutment rod 4. A swing plate 8 is rotatably connected to the vertical rod 7. The swing plate 8 is located on the side of the motor body 1 along the horizontal direction. The swing plate 8 includes a plate body 81 and a protrusion 82. The plate body 81 is rotatably connected to the vertical rod 7. The rotation axis of the plate body 81 is vertical. The plate body 81 is rotatably connected to the support 213 through cooperation with the vertical rod 7. The protrusion 82 is located on the side of the plate body 81 away from the motor body 1 and is fixedly connected to the plate body 81. The protrusion 82 is cylindrical.

[0052] See Figure 2 and Figure 6 Each support 213 is also provided with a transmission assembly 9, which includes a fixed rod 91, a transmission block 92 and an elastic element 93. The fixed rod 91 is located on the side of the upright 7 away from the motor body 1 and is fixedly connected to the support 213. The fixed rod 91 passes through a clearance hole 42. The transmission block 92 is located above the fixed rod 91 and on the side of the plate 81 away from the motor body 1. A sliding groove 921 is opened on the lower end face of the transmission block 92. The fixed rod 91 extends into the sliding groove 921. The transmission block 92 slides up and down on the fixed rod 91 through the cooperation of the fixed rod 91 and the sliding groove 921. A corrugated groove 922 is opened on the outer wall of the transmission block 92 near the plate 81. The length direction of the corrugated groove 922 is set vertically. The protrusion 82 extends into the corrugated groove 922 and abuts against the two opposite inner walls of the corrugated groove 922.

[0053] See Figure 2 and Figure 6 The elastic element 93 is located below the transmission block 92 and sleeved on the outside of the fixed rod 91. The elastic element 93 is located inside the relief hole 42. The opposite ends of the elastic element 93 are fixedly connected to the transmission block 92 and the support part 213, respectively. The elastic element 93 pulls the transmission block 92 so that the transmission block 92 abuts against the upper end face of the abutment rod 4. In this embodiment, the elastic element 93 is a spring.

[0054] In actual use, when the motor body 1 vibrates, the motor body 1 drives the slide rod 11 to move up and down repeatedly, which in turn drives the abutment rod 4 to rotate back and forth. The abutment rod 4 drives the transmission block 92 to move up and down repeatedly, so that the protrusion 82 slides along the inner wall of the corrugated groove 922, which in turn drives the plate 81 to swing back and forth to fan the surface of the motor body 1, accelerate the airflow on the surface of the motor body 1, and promote heat dissipation on the surface of the motor body 1.

[0055] See Figure 2 and Figure 7 Each transition section 212 is also fixed with a through rod 10. The through rod 10 is located on the side of the transition section 212 near the motor body 1 and passes through the abutment rod 4. A receiving block 12 slides up and down on the through rod 10. A receiving cavity 121 is opened in the receiving block 12. A piston 101 is fixed at the upper end of the through rod 10. The piston 101 is located in the receiving cavity 121 and abuts against the inner peripheral wall of the receiving cavity 121.

[0056] See Figure 2 and Figure 7An air inlet 122 is provided on the upper end face of the receiving block 12, which is connected to the receiving cavity 121. A one-way valve 14 is fixed on the receiving block 12. The one-way valve 14 is located inside the air inlet 122 and allows one-way flow from the outside of the receiving block 12 to the receiving cavity 121. A filter screen 13 is also fixed on the receiving block 12. The filter screen 13 is located inside the air inlet 122 and on the side of the one-way valve 14 away from the receiving cavity 121. The filter screen 13 covers the air inlet 122 and is located in the fan area of ​​the plate 81 and is flush with the upper end face of the receiving block 12.

[0057] See Figure 2 and Figure 7 A connecting pipe 15 is fixed on the upper end face of the receiving block 12. The end of the connecting pipe 15 away from the receiving block 12 is fixedly connected to the motor body 1. The connecting pipe 15 connects the receiving cavity 121 and the inside of the motor body 1. A one-way valve 16 is fixed inside the connecting pipe 15. The one-way valve 16 allows one-way flow from the receiving cavity 121 to the inside of the motor body 1.

[0058] See Figure 7 Each slide bar 11 has a toothed surface 111 machined on its outer side wall. The toothed surface 111 is located on the side of the slide bar 11 near the through rod 10 and is vertically arranged. The receiving block 12 has a toothed surface 123 machined on its outer side wall. The toothed surface 123 is located on the side of the receiving block 12 near the slide bar 11 and is vertically arranged. A linkage 17 is rotatably connected to the connecting part 211. The rotation axis of the linkage 17 is parallel to the rotation axis of the abutment rod 4. The linkage 17 is located between the toothed surface 111 and the toothed surface 123, and the linkage 17 meshes with the toothed surface 111 and the toothed surface 123. In this embodiment, the linkage 17 is a gear.

[0059] When the motor body 1 vibrates, the motor body 1 drives the slide bar 11 to move up and down repeatedly. The slider drives the linkage 17 to rotate through the cooperation of the tooth surface 111 and the linkage 17. The linkage 17 drives the receiving block 12 to move up and down repeatedly through the cooperation of the tooth surface 123. This continuously draws the cooler air outside the receiving block 12 into the receiving cavity 121 and sends the air from the receiving cavity 121 into the motor body 1. This allows the hot air inside the motor body 1 to leak through the gaps on the motor body 1, realizing the exchange between the hot air inside the motor body 1 and the cold air outside the motor body 1, and promoting heat dissipation inside the motor body 1.

[0060] In another embodiment, the linkage 17 can also be a linkage rod, which is hinged to the connecting part 211, and the hinge axis of the linkage rod is parallel to the rotation axis of the abutment rod 4. The two ends of the linkage rod are respectively inserted through the slide rod 11 and the receiving block 12. When the motor body 1 vibrates, the motor body 1 drives the slide rod 11 to move up and down repeatedly, thereby driving the linkage rod to flip back and forth, thereby driving the receiving block 12 to move up and down repeatedly.

[0061] The implementation principle of a vibration-damping and low-noise motor according to an embodiment of this application is as follows:

[0062] When the motor body 1 vibrates, the elastic force of the elastic element 18 buffers and dampens the motor body 1, reducing the impact of vibration on the motor body 1. At the same time, the elastic element 41 is pressed against the lower end of the slide rod 11 through the abutment rod 4, sharing the pressure on the elastic element 18, and together buffering the motor body 1, inhibiting elastic fatigue of the elastic element 18, which helps to extend the service life of the elastic element 18 and improve the durability of the vibration damping performance of the motor body 1. The vibration damping performance of the motor body 1 is improved from both direct and indirect aspects, which helps to extend the service life of the motor body 1.

[0063] During the vibration of the motor body 1, the sliding rod 11 drives the abutment rod 4 to reciprocate and rotate, causing the abutment rod 4 to drive the plate 81 to swing back and forth through the transmission component 9, fanning the surface of the motor body 1, accelerating the airflow on the surface of the motor body 1, promoting heat dissipation on the surface of the motor body 1, and driving the receiving block 12 to reciprocate and lift through the linkage component 17, realizing the exchange of hot air inside the motor body 1 and cold air outside the motor body 1, promoting heat dissipation inside the motor body 1, suppressing the temperature rise of the motor body 1, reducing the possibility of internal parts of the motor body 1 expanding due to excessive temperature, causing friction and noise between parts, which helps to reduce the noise generated by the operation of the motor body 1 and improves the noise reduction performance of the motor body 1.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
