Description

Technical Field

[0001] This utility model belongs to the field of motor cooling technology, and in particular relates to a cooling structure for a drive motor. Background Technology

[0002] A drive motor is a device that converts electrical energy into mechanical energy to provide driving force for vehicle movement. It can also convert mechanical energy into electrical energy and recover energy when the vehicle brakes. However, it generates a lot of heat during operation. The cooling fan removes the heat from the motor through forced ventilation to prevent the motor from overheating and maintain its normal operation.

[0003] Currently, when existing motor-driven heat dissipation fans are in use, the fan blades rub against the air at high speed, generating an electrostatic effect that attracts dust particles from the air. This can clog the fan's air inlet and outlet, reducing heat dissipation efficiency, causing the hardware temperature to rise, affecting its performance and stability, and in severe cases, potentially leading to hardware damage.

[0004] To address the aforementioned problems, this application proposes a cooling structure for a drive motor. Utility Model Content

[0005] The purpose of this invention is to provide a cooling structure for a drive motor, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a cooling structure for a drive motor, comprising: a motor and a tail unit housing; a filter screen located inside the tail unit housing, with an internal adapter shaft connecting to a bearing seat inside the cooling fan blades, used to intercept dust while simultaneously throwing the dust outwards by centrifugal force to maintain long-term filtration performance, and absorbent cotton installed on the outer ring frame of the filter screen to absorb the thrown-out dust particles; a water guide pipe located inside the tail unit housing between the filter screen and the filter screen, aligned with an arc-shaped groove at the tail of the tail unit housing, allowing immediate contact with incoming air to form a cooling effect, thereby improving the heat dissipation effect on the motor; an inlet pipe and an outlet pipe are provided at the top of the tail of the tail unit housing, and the bottom is connected to the water guide pipe via an adapter pipe.

[0008] Furthermore, the inner side of the outer ring frame is provided with a connecting rod connected to the adapter shaft, located on the side adjacent to the heat dissipation fan blades.

[0009] Furthermore, a support is provided inside the tail section near the tail section to form a rotatable connection with the outer protruding part of the outer ring frame.

[0010] Furthermore, the outer ring frame has an internal groove for installing absorbent cotton.

[0011] Furthermore, the interior of the bearing seat is provided with a protruding plate mechanism that engages with the groove on the outside of the adapter shaft to transmit rotational power.

[0012] Furthermore, the curved structure of the water pipe is aligned with the arc-shaped groove to intercept air in real time for cooling.

[0013] Furthermore, the water inlet pipe is used to input media of different temperatures according to the ambient temperature and the operating status of the motor.

[0014] This utility model has the following beneficial effects:

[0015] This invention allows the outer ring frame to be installed inside the tail section housing via the connection of the adapter shaft and the outer ring frame. At this time, the incoming air is filtered by the filter screen, which intercepts dust particles. Under the action of high-speed rotation, centrifugal force is generated, causing the dust to be thrown to the outer area and absorbed by the absorbent cotton. In this way, the internal mechanism is protected from dust, maintaining a stable operating state, improving the service life of the motor, and reducing the failure rate of components.

[0016] This invention increases the amount of air entering by opening an arc-shaped groove. The incoming air comes into contact with the water pipe immediately and is cooled by the internal cooling medium to form slightly cooler air. This slightly cooler air then enters the equipment to create an efficient cooling effect on the motor, promoting the loss of internal heat without producing water vapor, thus effectively improving the motor's operating performance.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please see Figure 1-6 As shown, this utility model is a drive motor cooling structure, including: a motor 1 and a tail unit housing 2;

[0030] The filter screen 6 is located inside the tail housing 2. Inside, there is a connecting shaft 9 that connects to the shaft seat 16 inside the cooling fan blade 4. It is used to intercept dust and throw the dust out through centrifugal force to maintain long-term filtration performance. The filter screen 6 is also equipped with an adsorption cotton 12 on the outer ring frame 10 to adsorb the dust particles thrown out.

[0031] The water guide pipe 5 is located inside the tail housing 2 between the filter screen 6 and the air inlet. It is aligned with the arc-shaped groove 3 at the tail of the tail housing 2 and comes into contact with the incoming air to form a cooling effect, which is used to improve the heat dissipation effect of the motor 1. The tail housing 2 has an inlet pipe 7 and an outlet pipe 8 at the top of the tail. The bottom is connected to the water guide pipe 5 through the adapter pipe 15.

[0032] This embodiment provides a drive motor that can accelerate cooling. After the incoming air is temperature-controlled by the water pipe 5, the filter 6 intercepts the impurities it carries. Under the drive of the fan blades 4, centrifugal force is generated, causing the dust to be thrown out and adsorbed onto the absorbent cotton 12. This arrangement can greatly improve the cooling efficiency of the motor 1 and prevent dust accumulation from causing heat buildup, thereby ensuring the stable operation of the motor 1 and improving its service life.

[0033] The outer ring frame 10 has a connecting rod 11 on its inner side that is connected to the adapter shaft 9. It is located on the side adjacent to the heat dissipation fan blade 4, so that the outer ring frame 10 and the filter screen 6 rotate together under the drive of the adapter shaft 9.

[0034] The tail housing 2 has a support 13 located in the area near the tail section. This support is used to connect with the outer protruding part of the outer ring frame 10 to form a rotatable connection. It is also used to position the frame for easy disassembly, cleaning, and use.

[0035] The outer ring frame 10 has an inner ring groove 14 for installing the absorbent cotton 12.

[0036] The bearing seat 16 has a protruding plate mechanism inside that engages with the groove on the outside of the adapter shaft 9 to transmit rotational power and achieve the effect of power reuse, thereby reducing the operating pressure of the equipment.

[0037] Among them, the curved structure of the water pipe 5 is aligned with the arc groove 3 to intercept air in real time for cooling treatment, and the arc groove 3 is used to increase the air intake flow.

[0038] The water inlet pipe 7 is used to input media of different temperatures according to the ambient temperature and the operating status of the motor 1, which can preheat the equipment under cold conditions such as winter.

[0039] It is understandable that this utility model can control the temperature of the incoming air in the first instance, which can not only cool down the motor 1 to accelerate its cooling, but also preheat the motor 1 in the cold winter environment to protect the components. In addition, it can intercept and discharge dust in the air, effectively preventing dust from accumulating on the surface of the components and affecting the operating status of the equipment.

[0040] A specific application of the operation process in this embodiment is as follows: In use, firstly, one side of the outer ring frame 10 is connected to the support 13. Then, when installing the tail housing 2, the shaft seat 16 can be directly connected to the adapter shaft 9. The rotation of the cooling fan 4 drives the filter screen 6 to rotate. After the filter screen 6 intercepts dust in the air, the centrifugal force during rotation throws the dust outward, which is then absorbed by the absorbent cotton 12 for easy subsequent cleaning. This effectively prevents dust from entering the adsorption elements inside the equipment and maintains the stable operation of the motor 1. At the same time, the air comes into contact with the water pipe 5 as soon as it enters, so that the air is cooled and blown into the interior of the motor 1, and prevents the cold air from becoming too cold and producing water vapor. After this arrangement, the heat dissipation performance of the motor 1 can be greatly improved, which is convenient for long-term continuous operation.
