Description

Technical Field

[0001] This invention relates to the field of electric motors, and more specifically, to an electric motor with high water resistance. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It utilizes a rotating magnetic field generated by a current-carrying coil to act on the rotor, creating magnetoelectric torque. Electric motors are classified into DC motors and AC motors according to the power source they use. Most motors in power systems are AC motors, which can be synchronous or asynchronous motors. An electric motor mainly consists of a stator and a rotor. The direction of the force on a current-carrying conductor in a magnetic field is related to the direction of the current and the direction of the magnetic field lines. The working principle of an electric motor is that the magnetic field exerts a force on the current, causing the motor to rotate.

[0003] In the existing technology, water-cooled motors are commonly used in electric vehicles. When a water-cooled motor is installed at the front of an electric vehicle, it is usually placed in one place. In humid weather, moisture may affect the motor, which may lead to safety hazards after the motor is installed and used. Summary of the Invention

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this invention is to provide an electric motor with high water resistance. This solution allows moisture to enter the motor after it has been placed aside. The moisture is initially removed by a first desiccant within a dehumidifying frame. Subsequently, when moisture accumulates inside the motor due to humid weather, a second desiccant actively absorbs the moisture, preventing it from affecting the battery components. After absorption, the second desiccant is then removed and absorbed by a sponge. The presence of moisture within the sponge causes the absorbent balls to absorb the water vapor. Simultaneously, the absorbed water melts the surface of the moisture-proof coating balls, causing the coating to flow into a fixed plate and gradually solidify to form a protective film. Because the film-forming material is insoluble in water, the coating has strong water resistance and provides excellent moisture protection, effectively preventing moisture re-entry.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A highly water-resistant electric motor includes an electric motor, a base fixedly connected to the lower end of the electric motor, a disc mounted on the right end of the electric motor, a battery cell assembly fixedly connected inside the electric motor, a sleeve fixedly connected to the left end of the disc, the sleeve penetrating the electric motor and mounted outside the battery cell assembly, multiple evenly distributed through holes drilled inside the sleeve, a dehumidifying frame inserted into the through holes, a filter screen fixedly connected to the inner wall of the dehumidifying frame, a bag fixedly connected to the inner wall of the dehumidifying frame, the bag located below the filter screen, the bag filled with a first desiccant, a perforated plate fixedly connected to the inner wall of the dehumidifying frame, the perforated plate located below the first desiccant, a fixing plate fixedly connected to the inner wall of the dehumidifying frame, the fixing plate located below the perforated plate, multiple evenly distributed water-absorbing balls fixedly connected to the upper end of the fixing plate, a moisture-proof coating ball fixedly connected inside the water-absorbing ball, two symmetrical outlet holes drilled at the outer end of the water-absorbing ball, the outlet holes communicating with the moisture-proof coating ball, the dehumidifying... A sponge is fixedly connected to the inner wall of the dehumidification frame, located at the lower end of the water-absorbing ball. A second desiccant is also fixedly connected to the inner wall of the dehumidification frame, located at the lower end of the sponge. This allows moisture to enter the motor after it is placed aside. The first desiccant in the bag inside the dehumidification frame initially removes the moisture. Subsequently, when moisture accumulates inside the motor due to humid weather, the second desiccant actively absorbs the moisture, preventing it from affecting the battery cell components. After the second desiccant absorbs moisture, the sponge removes and absorbs the moisture from it. When the sponge contains moisture, the water-absorbing ball absorbs the moisture, and the absorbed water melts the surface of the moisture-proof coating ball. This causes the moisture-proof coating inside the ball to flow into the fixed plate and gradually solidify to form a protective film. Because the film-forming material is insoluble in water, the coating has strong water resistance and provides excellent moisture protection, effectively preventing moisture from returning.

[0009] Furthermore, a base plate is fixedly connected to the outer end of the motor, and a humidity controller is fixedly connected to the outer end of the base plate. A condensation dehumidification mechanism is fixedly connected to the lower end of the humidity controller, and multiple evenly distributed drain outlets are fixedly connected to the lower end of the condensation dehumidification mechanism. After the dehumidification frame inside the sleeve removes the moisture generated inside and outside the motor, the humidity can be set by the humidity controller, and the moisture can be removed by the condensation dehumidification mechanism. The principle of the condensation dehumidification mechanism is to absorb and condense the water vapor inside the motor into liquid through a semiconductor condenser and discharge it through the drain outlet. The liquid then evaporates naturally into the air outside the motor, thus making the removal of moisture inside the motor more efficient.

[0010] Furthermore, the inner wall of the motor is chiseled with a slot, and a locking block is fixedly connected to the left end of the sleeve. The locking block is inserted into the slot. After the disc is inserted into the motor, the sleeve will also be inserted into the motor, and the sleeve will remove moisture from the motor. In order to make the sleeve more stable after being inserted into the motor, it can be fixed by locking the locking block into the slot, so that the sleeve is not easy to shake.

[0011] Furthermore, a groove is chiseled at the right end of the disc, and a handle is slidably connected to the inner wall of the groove. When the disc is installed on the motor, in order to make the installation of the disc more convenient, the handle can be pulled to make the disc easier to insert into the motor. At the same time, the handle can be used to make the disc drive the sleeve to insert more efficiently and quickly.

[0012] Furthermore, a compression spring is fixedly connected between the handle and the groove. When the disc is inserted into the motor by the pull of the handle, the handle will remain outside the groove. In order to prevent the handle from affecting the overall use of the motor, the compression spring can be used to automatically pull the handle into the groove after use, thereby maintaining the flatness of the disc surface.

[0013] Furthermore, a guide plate is fixedly connected to the bottom of the dehumidification frame. The guide plate is located below the second desiccant. When the second desiccant removes moisture from the motor, the moisture will enter the dehumidification frame. In order to make the second desiccant absorb moisture more evenly, the guide plate can guide the moisture to be evenly introduced onto the second desiccant and absorbed by it.

[0014] Furthermore, a pad is fixedly connected to the inner wall of the through hole. The pad is located at the outer end of the dehumidification frame. After the dehumidification frame is inserted into the through hole, in order to make the dehumidification frame more stable after insertion, the pad can be used to clamp the dehumidification frame, thereby increasing the stability of the dehumidification frame and making it less likely for the dehumidification frame to slip into the battery cell assembly.

[0015] Furthermore, two symmetrical extension blocks are fixedly connected to the lower end of the bag. The extension blocks are fixedly connected to the perforated plate. After the bag is placed in the dehumidification frame, in order to maintain a certain distance between the bag and the perforated plate, the extension blocks can be used to block the bag, thereby maintaining a certain distance between the perforated plate and the bag, allowing air to circulate more effectively.

[0016] Furthermore, the humidity controller is fitted with a protective sleeve on its outer end, which protects the humidity controller from wear caused by the use of the motor.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of this invention are:

[0019] (1) This solution can achieve the following: after the motor is placed aside, the moisture enters the motor and enters the dehumidification frame. The first desiccant in the bag will initially remove the moisture. Then, when the motor generates moisture inside due to humid weather, the second desiccant will actively adsorb the moisture, so that the moisture will not easily affect the battery cell components. After the second desiccant is adsorbed, the sponge will export and absorb the moisture on the second desiccant. When the sponge contains moisture, the water-absorbing ball will absorb the water vapor. At the same time, the absorbed water will melt the surface of the moisture-proof coating ball, so that the moisture-proof coating in the moisture-proof coating ball will flow into the fixed plate and gradually solidify to form a protective film. Since its film-forming material is insoluble in water, the coating has strong water resistance and can play a good moisture-proof effect, which can effectively prevent the return of moisture.

[0020] (2) A base plate is fixedly connected to the outer end of the motor, and a humidity controller is fixedly connected to the outer end of the base plate. A condensation dehumidification mechanism is fixedly connected to the lower end of the humidity controller. Multiple evenly distributed drain outlets are fixedly connected to the lower end of the condensation dehumidification mechanism. After the dehumidification frame inside the sleeve removes the moisture generated inside and outside the motor, the humidity can be set by the humidity controller, and the moisture can be removed by the condensation dehumidification mechanism. The principle of the condensation dehumidification mechanism is to absorb the water vapor inside the motor and condense it into liquid through the semiconductor condensation device and discharge it through the drain outlet. The liquid is then naturally evaporated into the air outside the motor, which makes the removal of moisture inside the motor more efficient.

[0021] (3) The inner wall of the motor is chiseled with a slot, and the left end of the sleeve is fixedly connected with a block. The block is inserted into the slot. After the disc is inserted into the motor, the sleeve will also be inserted into the motor, and the sleeve will remove the moisture in the motor. In order to make the sleeve more stable after being inserted into the motor, the block can be inserted into the slot to fix it, so that the sleeve is not easy to shake.

[0022] (4) A groove is chiseled on the right end of the disc, and a handle is slidably connected to the inner wall of the groove. When the disc is installed on the motor, in order to make the disc easier to install, the handle can be pulled to make the disc easier to insert into the motor. At the same time, the handle can be used to make the disc drive the sleeve to insert more efficiently and quickly.

[0023] (5) A compression spring is fixedly connected between the handle and the groove. When the disc is inserted into the motor by the pull of the handle, the handle will remain outside the groove. In order to prevent the handle from affecting the overall use of the motor, the handle can be automatically pulled into the groove after use by the compression spring, so as to maintain the flatness of the disc surface.

[0024] (6) A guide plate is fixedly connected to the bottom of the dehumidification frame. The guide plate is located below the second desiccant. When the second desiccant removes moisture from the motor, the moisture will enter the dehumidification frame. In order to make the desiccant absorb moisture more evenly, the moisture can be evenly introduced into the second desiccant and absorbed by the second desiccant through the guide plate.

[0025] (7) A pad is fixedly connected to the inner wall of the through hole. The pad is located at the outer end of the dehumidification frame. After the dehumidification frame is inserted into the through hole, in order to make the dehumidification frame more stable after insertion, the pad can be used to clamp the dehumidification frame, thereby increasing the stability of the dehumidification frame and making it less likely for the dehumidification frame to slip into the battery cell assembly.

[0026] (8) Two symmetrical extension blocks are fixedly connected to the lower end of the bag. The extension blocks are fixedly connected to the perforated plate. After the bag is placed in the dehumidification frame, in order to keep a certain distance between the bag and the perforated plate, the extension blocks can be used to block the bag, thereby keeping a certain distance between the perforated plate and the bag, so that the air can circulate more.

[0027] (9) A protective sleeve is provided on the outer end of the humidity controller to protect the humidity controller and prevent wear caused by the use of the motor. Attached Figure Description

[0039] Example

[0040] Please see Figure 1-6A highly water-resistant electric motor includes an electric motor 1, a base 2 fixedly connected to the lower end of the electric motor 1, a disc 3 mounted on the right end of the electric motor 1, a battery cell assembly 4 fixedly connected inside the electric motor 1, and a sleeve 5 fixedly connected to the left end of the disc 3. The sleeve 5 penetrates the electric motor 1 and is mounted on the outside of the battery cell assembly 4. Multiple evenly distributed through holes 6 are drilled inside the sleeve 5, and a dehumidifying frame 7 is inserted into each through hole 6. A filter screen 8 is fixedly connected to the inner wall of the dehumidifying frame 7, and a bag 9 is fixedly connected to the inner wall of the dehumidifying frame 7, located below the filter screen 8. The bag 9 is filled with a first desiccant 10. A perforated plate 11 is fixedly connected to the inner wall of the dehumidification frame 7, located below the first desiccant 10. A fixing plate 12 is fixedly connected to the inner wall of the dehumidification frame 7, located below the perforated plate 11. Multiple evenly distributed water-absorbing balls 13 are fixedly connected to the upper end of the fixing plate 12. Moisture-proof coating balls 14 are fixedly connected inside the water-absorbing balls 13. Two symmetrical outlet holes 15 are drilled at the outer end of the water-absorbing balls 13, and the outlet holes 15 are connected to the moisture-proof coating balls 14. The inner wall of the dehumidification frame 7 is fixedly connected to... A sponge 16 is located at the lower end of the absorbent ball 13. A second desiccant 17 is fixedly connected to the inner wall of the dehumidification frame 7, located at the lower end of the sponge 16. This allows moisture to enter the motor 1 after it is placed aside. The moisture is initially removed by the first desiccant 10 in the bag 9 within the dehumidification frame 7. Subsequently, when moisture accumulates inside the motor 1 due to humid weather, the second desiccant 17 actively absorbs the moisture, thus preventing moisture from easily damaging the battery cell assembly. The effect of component 4 is that after the second desiccant 17 is adsorbed, the moisture on the second desiccant 17 is then carried out and absorbed by the sponge 16. When the sponge 16 contains moisture, the water-absorbing ball 13 will absorb the water vapor. At the same time, the absorbed water melts the surface of the moisture-proof coating ball 14, causing the moisture-proof coating in the moisture-proof coating ball 14 to flow into the fixing plate 12 and gradually solidify to form a protective film. Since its film-forming material is insoluble in water, the coating has strong water resistance and can play a good moisture-proof role, effectively preventing the re-dampness effect.

[0041] Please see Figure 1 A base plate 18 is fixedly connected to the outer end of the motor 1, and a humidity controller 19 is fixedly connected to the outer end of the base plate 18. A condensation dehumidification mechanism 20 is fixedly connected to the lower end of the humidity controller 19. Multiple evenly distributed drain outlets 21 are fixedly connected to the lower end of the condensation dehumidification mechanism 20. After the dehumidification frame 7 in the sleeve 5 removes the moisture generated inside and outside the motor 1, the humidity can be set by the humidity controller 19, and the moisture can be removed by the condensation dehumidification mechanism 20. The principle of the condensation dehumidification mechanism 20 is to absorb and condense the water vapor in the motor 1 into liquid through a semiconductor condensation device and discharge it through the drain outlet 21. The liquid then evaporates naturally into the air outside the motor 1, which makes the removal of moisture in the motor 1 more efficient.

[0042] Please see Figure 3-6 The inner wall of the motor 1 has a groove 101. A locking block 501 is fixedly connected to the left end of the sleeve 5, and the locking block 501 is inserted into the groove 101. After the disc 3 is inserted into the motor 1, the sleeve 5 will also be inserted into the motor 1, and the sleeve 5 will remove moisture from the motor 1. To make the sleeve 5 more stable after being inserted into the motor 1, the locking block 501 can be inserted into the groove 101 for fixation, thus preventing the sleeve 5 from shaking. The right end of the disc 3 has a groove 301, and a handle 302 is slidably connected to the inner wall of the groove 301. When the disc 3 is installed on the motor 1, to make... The disc 3 is more convenient to install. Pulling the handle 302 makes it easier to insert the disc 3 into the motor 1. Simultaneously, the handle 302 allows the disc 3 to drive the sleeve 5 for more efficient and faster insertion. A compression spring 303 is fixedly connected between the handle 302 and the groove 301. When the disc 3 is inserted into the motor 1 by the handle 302, the handle 302 will remain outside the groove 301. To prevent the handle 302 from affecting the overall operation of the motor 1, the compression spring 303 allows the handle 302 to be automatically pulled back into the groove 301 after use. Inside, to maintain the flatness of the surface of the disc 3, a guide plate 701 is fixedly connected to the bottom of the dehumidification frame 7. The guide plate 701 is located below the second desiccant 17. When the second desiccant 17 absorbs moisture in the motor 1, the moisture will enter the dehumidification frame 7. In order to make the absorption of moisture by the second desiccant 17 more uniform, the guide plate 701 can guide the moisture to be evenly introduced onto the second desiccant 17 for absorption. A pad 601 is fixedly connected to the inner wall of the through hole 6. The pad 601 is located at the outer end of the dehumidification frame 7. After the dehumidification frame 7 is inserted into the through hole 6, in order to make the dehumidification frame 7 more uniform, the guide plate 701 can guide the moisture to be evenly absorbed by the second desiccant 17. The dehumidification frame 7 is more stable after insertion. The dehumidification frame 7 can be clamped by the pad 601, thereby increasing the stability of the dehumidification frame 7 and making it less likely to slip into the through hole 6 onto the battery cell assembly 4. The lower end of the bag 9 is fixedly connected to two symmetrical extension blocks 1001. The extension blocks 1001 are fixedly connected to the hollow plate 11. After the bag 9 is placed in the dehumidification frame 7, in order to maintain a certain distance between the bag 9 and the hollow plate 11, the extension blocks 1001 can be used to block the bag 9, thereby maintaining a certain distance between the hollow plate 11 and the bag 9, allowing air to circulate better.

[0043] Please see Figure 1 The humidity controller 19 is fitted with a protective sleeve on its outer end, which can protect the humidity controller 19 and prevent it from being worn by the motor 1.

[0044] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
