Description

Technical Field

[0001] The utility model relates to the technical field of protection components, in particular to a protection component for an electric drive system assembly. Background Technique

[0002] The electric drive system assembly is a crucial part of modern new energy vehicles. It replaces the traditional internal combustion engine drive system and drives the vehicle through electric power. Its working principle is that during vehicle driving, the battery provides power to the motor. The motor generates kinetic energy through rotation and transmits the power to the gearbox. The gearbox converts the power of the motor and then transmits it to the wheels through the output shaft to drive the vehicle. At the same time, the controller adjusts the output power and torque of the motor in real time according to information such as vehicle speed and accelerator pedal position to achieve the best driving performance and energy efficiency. During deceleration or braking, the motor can also be used as a generator to convert the kinetic energy of the vehicle into electric energy for storage, improving energy utilization efficiency. Currently, most electric heavy trucks' electric drive system assemblies are connected to the vehicle frame through a four-point suspension method, which causes the electric drive system assembly to be easily affected by foreign objects such as sand and gravel on the ground during operation. To avoid damage to the electric drive system assembly, a protection component is usually installed on its surface to improve its service life.

[0003] In the prior art, as disclosed in Chinese Patent CN220639526U, "a protection component for an electric drive system assembly", it includes a protective cover for covering the bottom and side parts of the electric drive system assembly. The protective cover is installed between the vehicle frame and the support arm of the electric drive system assembly through a connecting piece.

[0004] Although the above-mentioned utility model can block the bottom surface and the side surface close to the bottom surface of the electric drive system assembly through the protective cover, avoiding collisions and scratches between sand and gravel and other sundries on the road surface and the shell of the electric drive system assembly, and improving the protection ability of the electric drive system assembly, the electric drive system assembly generates heat continuously during operation, and the generated heat cannot be dissipated in time due to the blocking of the protective cover. During long-term operation, it is easy to cause the electric drive system assembly to overheat, affecting its service life. Content of the Utility Model

[0005] The purpose of the utility model is to provide a protection component for an electric drive system assembly to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A protective component for an electric drive system assembly, including a protective cover. Four mounting through holes are penetrated through both sides of the protective cover, and four small fans are fixedly connected inside the four mounting through holes. A heat conducting sheet is fixedly connected to the inner bottom surface of the protective cover, and the bottom surface of the heat conducting sheet penetrates through the inner bottom surface of the protective cover.

[0007] As a further preference of this technical solution, a flow guiding cover is fixedly connected to one side of each of the four small fans, and a filtering cover is fixedly connected to the top end of each of the four flow guiding covers.

[0008] As a further preference of this technical solution, protection plates are fixedly connected to both sides of the protective cover and at positions on both sides of the four small fans.

[0009] As a further preference of this technical solution, three oil drain holes are penetrated through the inner bottom surface of the protective cover, and a maintenance hole is penetrated through one side of the protective cover.

[0011] As a further preference of this technical solution, two mounting plates are fixedly connected to both inner side walls of the protective cover and near the upper edge position.

[0012] The present utility model provides a protective component for an electric drive system assembly, having the following beneficial effects:

[0013] In the present utility model, the small fans blow air from the outside into the protective cover, so that the air flows rapidly on the surface of the electric drive system assembly and flows out from the gaps of the protective cover, enabling the air to carry away the heat dissipated from the surface of the electric drive system assembly, achieving the effect of cooling the electric drive system assembly, preventing overheating, and the heat conducting sheet rapidly conducts the heat in the air passing through the bottom surface of the protective cover to the outside, further reducing the residence time of heat in the protective cover and further improving the heat dissipation efficiency and the service life of the electric drive system assembly.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] The utility model provides a technical solution: Figures 1-3 As shown, in the present embodiment, a protective component of an electric drive system assembly includes a protective cover 1, four mounting through holes 2 are formed through both sides of the protective cover 1, small fans 3 are fixedly connected to the inside of the four mounting through holes 2, a heat conductive sheet 7 is fixedly connected to the bottom surface of the inside of the protective cover 1, and the bottom surface of the heat conductive sheet 7 passes through the bottom surface of the inside of the protective cover 1, wherein, by arranging the small fan 3, the outside air can be sent into the inside of the protective cover 1, and a high-speed airflow is formed to flow along the surface of the electric drive system assembly, and the heat generated by its operation is taken away to achieve a cooling effect, and by arranging the heat conductive sheet 7, the heat in the airflow can be conducted to the outside, and the time that the heat stays in the protective cover 1 is reduced.

[0020] like Figure 2 and Figure 3 As shown, one side of the four small fans 3 is fixedly connected to a deflector 4, and the top of the four deflector 4 is fixedly connected to a filter cover 5. By setting the deflector 4, air can be drawn from above to prevent the vehicle from bringing water directly into the protective cover 1 when passing through a water environment. By setting the filter cover 4, larger impurities in the air can be blocked to prevent damage to internal components.

[0021] like Figure 1 As shown, protective plates 11 are fixedly connected on both sides of the protective cover 1 and located on both sides of the four small fans 3. By providing the protective plates 11, it is possible to prevent the small fans 3 or the air guide cover 5 from being directly hit and damaged by objects such as stones during the operation of the vehicle, thereby improving the service life.

[0022] like Figure 2 and Figure 3 As shown, three oil drain holes 8 are opened through the inner bottom surface of the protective cover 1, and an inspection hole 9 is opened through one side of the protective cover 1. The oil drain holes 8 can facilitate oil drainage, and the inspection hole 9 can facilitate inspection and maintenance.

[0023] like Figure 3 As shown, the three oil drain holes 8 and the inspection hole 9 are all clamped with sealing covers 10. By setting the sealing covers 10, the three oil drain holes 8 and the inspection hole 9 can be sealed to prevent water and other impurities from entering the protective cover 1.

[0024] As Figure 1 and Figure 2 shown, two mounting plates 6 are fixedly connected to both inner side walls of the protective cover 1 near the upper edge positions for fixing with the electric drive system assembly, facilitating installation.

[0025] The present utility model provides a protection component for an electric drive system assembly, and the specific working principle is as follows:

[0026] The protective cover 1 is fixedly connected to the outer surface of the electric drive system assembly through the mounting plates 6. During the operation of the electric drive system assembly, the small fan 3 starts. The small fan 3 blows air from the outside into the protective cover 1, causing the air to flow rapidly on the surface of the electric drive system assembly and flow out from the gaps of the protective cover 1, enabling the air to carry away the heat dissipated from the surface of the electric drive system assembly. Moreover, the heat conducting fins 7 rapidly conduct the heat in the air passing through the bottom surface of the protective cover 1 to the outside, further reducing the time for heat to remain in the protective cover 1, cooling the electric drive system assembly, and preventing it from overheating during long-term operation.

[0027] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
