Description

Technical Field

[0001] This utility model belongs to the field of electric motors, and more specifically, it relates to a cooling housing for a drive motor. Background Technology

[0002] As the new energy market expands, electric vehicles are gaining an increasingly larger market share. The main component of an electric vehicle is the electric motor, which converts electrical energy into mechanical energy. As the motor speed increases, the heat generated during motor rotation also increases. Excessive temperature can cause the magnets in the motor to become magnetic, leading to motor malfunction. Therefore, it is necessary to cool down the motor.

[0003] There are two common methods for motor cooling: air cooling and water cooling. Both have their advantages and disadvantages. At low ambient temperatures, air cooling is sufficient, eliminating the need for water cooling. However, using liquid cooling in such cases would result in excessive energy consumption. At high ambient temperatures or during prolonged operation, the motor overheats, and air cooling becomes insufficient, necessitating liquid cooling. Circulating liquid water continuously cools the motor, ensuring stable operation. This invention primarily addresses the challenge of combining air and liquid cooling, allowing for flexible switching between cooling methods while conserving energy.

[0004] To address the aforementioned technical problems, this application proposes a solution. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a cooling housing for a drive motor, which adopts a heat dissipation method that combines air cooling and liquid cooling, and the switching is more flexible. It can not only efficiently cool the motor, but also save energy.

[0006] A cooling housing for a drive motor includes a rotating sealing mechanism, a housing, a drive mechanism, and a protective cover. The housing includes an inner circular shell, with circular plates fixedly connected to both ends of the inner circular shell along its length. Multiple arc holes are evenly formed on the circular plates, and a rotor hole is formed in the middle of the circular plates. An annular groove is formed in the middle of the circular plates along their thickness, with the depth of the annular groove matching the width of the arc holes. Multiple sets of fins are fixedly connected to the inner circular shell between two of the circular plates. Each set of fins is located between two arc holes on the same circular plate. Multiple water-permeable holes are formed at the connection between the fins and the inner circular shell.

[0007] Preferably, the rotating sealing mechanism includes two ring teeth, and multiple arc plates are uniformly fixedly connected to one side of the inner side of the ring teeth. The size and number of the arc plates are consistent with the arc holes. The ring teeth are located outside the circular plate. A connecting plate is fixedly connected to one end of the arc plate. One side of the connecting plate abuts against the inner circular shell. Multiple through holes are opened on the connecting plate.

[0008] Preferably, a protective cover is fixedly connected to the outer side of the outer shell, and the two ends of the protective cover in the length direction abut against one side of the circular plate. A rotating shaft limiter is fixedly connected to the two ends of the outer length direction of the protective cover, and a rotating shaft hole is opened on each of the rotating shaft limiters. Two water inlets and two water outlets are opened at the two ends of the outer length direction of the protective cover.

[0009] Preferably, the driving mechanism includes a rotating shaft rotatably connected to a rotating shaft hole, with a gear one fixedly connected to both ends of the rotating shaft. The gear one is meshed with a ring gear for transmission. A gear three is also fixedly connected to the rotating shaft. A drive motor is fixedly connected to a protective cover on one side of the gear three. A gear two is fixedly connected to the extended end of the drive motor for meshing and transmission.

[0010] Preferably, an inlet pipe is sealed to the inlet hole, and an outlet pipe is sealed to the outlet hole; both the inlet pipe and the outlet pipe are tee pipes.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This innovative design integrates both air cooling and liquid cooling into a single generator casing. When the ambient temperature is low, the drive mechanism rotates the rotary sealing mechanism, opening the arc plate and arc hole, allowing air to freely enter and exit. The heat generated by the motor is transferred to the air via the fins for cooling. When the ambient temperature is too high and passive cooling is insufficient, the drive mechanism rotates the rotary sealing mechanism, closing the arc plate and arc hole, forming a sealed cavity between the casing and the protective cover. Cooling water enters through the inlet, filling the entire cavity, and carries away the heat, which then flows out through the outlet. This design is suitable for use at different temperatures while also saving energy. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] like Figures 1 to 5 As shown, a cooling housing for a drive motor includes a rotary sealing mechanism 2, a housing 3, a drive mechanism 5, and a protective cover 6. The housing 3 includes an inner circular shell 303. Figure 2 As shown, the inner circular shell 303 has circular plates 301 fixedly connected to both ends along its length. Multiple arc holes 302 are evenly opened on the circular plates 301, and a rotor hole 307 is opened in the middle of the circular plates 301. A rotor is installed in the internal cavity for rotation. A ring groove 304 is formed in the middle of the thickness direction of the circular plate 301. The depth of the ring groove 304 is the same as the width of the arc hole 302. Multiple sets of fins 305 are fixedly connected to the inner circular shell 303 between the two circular plates 301. Each set of fins 305 is located between two arc holes 302 on the same circular plate 301. Multiple water-permeable holes 306 are formed at the connection between the fins 305 and the inner circular shell 303. The advantage of placing the fins 305 in this position is that it will not affect the normal rotation of the rotating sealing mechanism 2. Furthermore, the multiple water-permeable holes 306 on the fins 305 are designed to facilitate the drainage of liquid between the fins 305 when the chamber between the outer shell 3 and the protective cover 6 changes from being filled with liquid to being emptied.

[0022] like Figure 3As shown, the rotating closing mechanism 2 includes two ring teeth 201. Multiple arc plates 202 are uniformly fixedly connected to one side of the inner side of each ring tooth 201. The size and number of the arc plates 202 are consistent with the arc holes 302, used to open and close the arc plates 202 and the arc holes 302. The ring teeth 201 are located outside the circular plate 301. A connecting plate 203 is fixedly connected to one end of each arc plate 202. One side of the connecting plate 203 abuts against the inner circular shell 303. Multiple through holes 204 are provided on the connecting plate 203.

[0023] like Figure 4 As shown, a protective cover 6 is fixedly connected to the outer side of the outer shell 3. The two ends of the protective cover 6 in the length direction abut against one side of the circular plate 301, so as to achieve a sealed connection between the protective cover 6 and the two circular plates 301. A rotating shaft limiter 601 is fixedly connected to the two ends of the outer length direction of the protective cover 6. Each rotating shaft limiter 601 has a rotating shaft hole 602. Two water inlet holes 603 and two water outlet holes 604 are opened at the two ends of the outer length direction of the protective cover 6.

[0024] like Figure 5 As shown, the drive mechanism 5 includes a rotating shaft 504 rotatably connected to the rotating shaft hole 602. Gear 1 501 is fixedly connected to both ends of the rotating shaft 504, and gear 1 501 meshes with ring gear 201 for transmission. Gear 3 505 is also fixedly connected to the rotating shaft 504. A drive motor 503 is fixedly connected to a protective cover 6 on one side of gear 3 505. Gear 2 502 is fixedly connected to the extended end of the drive motor 503 for transmission. Since the drive motor 503 does not require frequent starting, common air cooling is sufficient for its heat dissipation.

[0025] The water inlet 603 is sealed with a water inlet pipe 1, and the water outlet 604 is sealed with a water outlet pipe 4. Both the water inlet pipe 1 and the water outlet pipe 4 are T-shaped pipes. The advantage of the T-shaped pipe is that, since both the water outlet 604 and the water inlet 603 have two holes, which are set at both ends of the protective cover 6, it is convenient that no matter how the motor is placed, there will always be a hole at the bottom to facilitate the entry and exit of liquid.

[0026] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.

[0027] Working process: When the ambient temperature is low, the drive motor 503 in the drive mechanism 5 drives the gear 2 502 to rotate, which in turn drives the gear 3 505 to rotate. The gear 1 501 at both ends of the rotating shaft 504 connected to the gear 3 505 drives the ring gears 201 on both sides to rotate, causing the arc hole 302 to coincide with the arc plate 202, connecting the space between the outer shell 3 and the protective cover 6 to the external space. During vehicle operation, wind enters the cavity between the outer shell 3 and the protective cover 6. The fins 305 in the cavity transfer the heat generated by the rotor rotation to the fins 305, which are then carried away by the flowing wind. In summer when the ambient temperature is high or during long-term vehicle operation, the arc hole 302 and the arc plate 202 close, forming a sealed cavity between the outer shell 3 and the protective cover 6. Coolant enters the cavity through the inlet pipe 1 and the inlet hole 603. The coolant passes through the through hole and fills the entire cavity, carrying away the heat, and then flows out through the outlet hole 604 and the outlet pipe 4, completing the heat dissipation.

[0028] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
