Among them, when the generator generates electricity, the internal temperature is relatively high. Usually, a plurality of air inlet holes communicating with the inside of the generator are provided on the generator housing. At the same time, the generator housing is also provided with an exhaust hole communicating with the inside of the generator. The air is introduced through the air inlet holes to purge and cool the inside of the generator, and the exhaust is discharged through the exhaust hole. However, when there is a lot of dust, debris, etc. in the external environment where the generator is located, it will affect the working performance and service life of the generator. Therefore, in the prior art, for a generator applied to a vehicle, the engine and the generator are usually integrated in the same integrated housing, and then a total air inlet and a total air outlet are provided on the integrated housing, and an air filter is connected to the input end of the total air inlet so as to filter the air conveyed to the engine and the generator. However, integrating them in the same integrated housing will increase the number of components, resulting in high production costs; secondly, as the working time increases, there is also a risk of dust and debris deposition in the integrated housing. Content of the Utility Model

[0003] The purpose of the utility model is to provide a generator unit and a vehicle to solve the above problems existing in the prior art in the way of filtering dust, debris, etc. in the air for a generator applied to a vehicle.

[0008] As a preferred scheme of the above generator unit, the generator further includes a stator, a rotor shaft and a built-in fan. The stator is fixedly arranged in the generator housing and sleeved on the rotor shaft with a gap. The rotor shaft is rotatably connected to the generator housing and partially extends out of the generator housing. The built-in fan is located in the generator housing and fixedly sleeved on the rotor shaft;

[0009] The built-in fan, the stator, and the exhaust passage are sequentially spaced apart along the axial direction of the rotor shaft; the gas entering the generator housing from the intake passage can be blown by the built-in fan towards the stator.

[0010] As a preferred solution of the above generator unit, a transmission wheel is provided at one end of the rotor shaft extending out of the generator housing, and the crankshaft of the engine is in transmission connection with the transmission wheel and can drive the transmission wheel to rotate around its own central axis.

[0017] Advantages of the present utility model:

[0018] The present utility model provides a generator unit and a vehicle. Among them, the generator unit includes an independently provided engine, a generator, and an air filter. The generator includes a generator housing provided with an intake passage and an exhaust passage that communicate with the inside of the generator. The first output end of the air filter is in communication with the intake end of the engine. The second output end of the air filter is in communication with the intake passage.

[0019] The generator unit has the engine, generator, and air filter independently arranged. The first output end of the air filter is connected to the intake end of the engine, and the second output end of the air filter is connected to the intake passage. It can be understood that the engine and the generator share one air filter, but the air filter separately supplies filtered air to the engine and the generator, so that there is no need to set an integrated housing to integrate the engine and the generator in the integrated housing as in the prior art, effectively reducing the number of components, lowering the production cost, and improving the assembly efficiency. Secondly, compared with the prior art, it can also effectively avoid the risk of dust, debris, etc. deposited in the integrated housing entering the generator.

[0020] Secondly, the first output end of the air filter is connected to the intake end of the engine through a pipeline, the second output end of the air filter is connected to the intake passage through a pipeline, and multiple intake holes in the prior art are replaced by a single intake passage, resulting in less structural modification to the engine and the generator, reducing the design difficulty and processing difficulty. Secondly, replacing multiple intake holes in the prior art with a single intake passage can effectively reduce the difficulty of filtered air entering the generator and increase the air flow rate into the generator, thereby effectively improving the efficiency of cooling the generator.

[0032] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0033] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over", and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "under", and "beneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0035] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] As a power generation device, a generator can generate electricity and supply electrical energy to electrical components such as a vehicle controller when applied to a vehicle. Among them, when the generator generates electricity, the internal temperature is relatively high. Usually, there are multiple air inlet holes connected to the inside of the generator on the generator housing. At the same time, the generator housing is also provided with an exhaust hole connected to the inside of the generator. The air is introduced through the air inlet hole to purge and cool the inside of the generator, and the air is exhausted through the exhaust hole. However, when there is a lot of dust, debris, etc. in the external environment where the generator is located, it will affect the working performance and service life of the generator. Therefore, in the prior art, for a generator applied to a vehicle, the engine and the generator are usually integrated in the same integrated housing, and then a total air inlet and a total air outlet are provided on the integrated housing, and an air filter is connected to the input end of the total air inlet so that the air delivered to the engine and the generator can be filtered. However, integrating them in the same integrated housing will increase the number of components, resulting in high production costs; secondly, as the working hours increase, there is also a risk of dust, debris, etc. accumulating in the integrated housing.

[0037] As Figures 1 - 3 shown, the present utility model provides a generator unit, including an independently provided engine 1, a generator 2, and an air filter 3. The generator 2 includes a generator housing 21. The generator housing 21 is provided with an air inlet passage 211 and an exhaust passage 212 that communicate with the inside of the generator 2. The first output end 31 of the air filter 3 is communicated with the air inlet end of the engine 1. The second output end 32 of the air filter 3 is communicated with the air inlet passage 211.

[0038] The generator unit independently arranges the engine 1, the generator 2, and the air filter 3, and communicates the first output end 31 of the air filter 3 with the air inlet end of the engine 1, and the second output end 32 of the air filter 3 with the air inlet passage 211. It can be understood that the engine 1 and the generator 2 share an air filter 3, but the air filter 3 separately supplies filtered air to the engine 1 and the generator 2, so that compared with the prior art, there is no need to set an integrated housing to integrate the engine 1 and the generator 2 in the integrated housing, effectively reducing the number of components, reducing the production cost, and improving the assembly efficiency; secondly, compared with the prior art, it can also effectively avoid the risk of dust, debris, etc. deposited in the integrated housing from entering the inside of the generator 2.

[0039] Secondly, the first output end 31 of the air filter 3 is communicated with the air inlet end of the engine 1 through a pipeline, the second output end 32 of the air filter 3 is communicated with the air inlet passage 211 through a pipeline, and the multiple air inlet holes in the prior art are replaced with a single air inlet passage 211, so that the structural modifications to the engine 1 and the generator 2 are small, reducing the design difficulty and processing difficulty; secondly, replacing the multiple air inlet holes in the prior art with a single air inlet passage 211 can effectively reduce the difficulty of the filtered air entering the inside of the generator 2, and increase the air flow rate entering the generator 2, thereby effectively improving the efficiency of cooling the generator 2.

[0040] Optionally, as Figures 1 - 3 shown, the pipeline connecting the second output end 32 of the air filter 3 to the intake passage 211 is the intake pipeline 4, and a heat insulation layer is provided on the outer periphery of the intake pipeline 4. With this setting, it is possible to reduce the influence of the heat dissipation of the engine 1, etc. on the temperature of the air delivered into the intake passage 211, so that the air entering the interior of the generator 2 can effectively cool the generator 2.

[0041] In this embodiment, exemplarily, the heat insulation layer is made of heat insulation cotton. In other embodiments, the heat insulation layer can also be made of heat insulation metal, etc.

[0042] As an alternative, the intake pipeline 4 is made of heat insulation metal.

[0043] Among them, as Figure 1 shown, the generator 2 further includes a stator 22, a rotor shaft 23 and a built-in fan 24. The stator 22 is fixedly arranged in the generator housing 21 and is sleeved on the rotor shaft 23 with a gap. The rotor shaft 23 is rotatably connected to the generator housing 21 and partially extends out of the generator housing 21. The built-in fan 24 is located in the generator housing 21 and is fixedly sleeved on the rotor shaft 23. The built-in fan 24, the stator 22 and the exhaust passage 212 are sequentially and spaced apart along the axial direction of the rotor shaft 23. The gas entering the generator housing 21 from the intake passage 211 can be blown towards the stator 22 by the built-in fan 24. With this setting, the air entering the generator housing 21 from the intake passage 211 can be evenly blown towards the stator 22 and the rotor, thereby effectively improving the heat dissipation uniformity of the generator 2.

[0044] Specifically, as Figure 1 shown, a transmission wheel 7 is provided at one end of the rotor shaft 23 extending out of the generator housing 21. The crankshaft of the engine 1 is in transmission connection with the transmission wheel 7 and can drive the transmission wheel 7 to rotate around its own central axis. With this setting, the rotor shaft 23 can be driven to rotate around its own central axis, so that the generator 2 can generate electricity.

[0045] Further, in this embodiment, the transmission wheel 7 is a belt wheel, the belt wheel is fixedly sleeved on the rotor shaft 23, and the central axis of the transmission wheel 7 is collinear with the central axis of the rotor shaft 23.

[0046] In other embodiments, the transmission wheel 7 can also be a gear. As long as it can drive the rotor shaft 23 to rotate around its own central axis so that the generator 2 can generate electricity.

[0047] Specifically, as Figure 1 shown, along the axial direction of the rotor shaft 23, the transmission wheel 7 is located on the side close to the intake passage 211.

[0048] Preferably, as Figure 1As shown, the intake passage 211 partially extends out of the circumferential exterior of the generator housing 21. This is arranged to avoid interference between the intake passage 211 and the drive wheel 7, and also facilitates the assembly of the drive wheel 7 and the intake pipeline 4.

[0049] Optionally, as Figures 1 - 3 shown, the intake passage 211 is located above the exhaust passage 212. This is conducive to the discharge of the heat-carrying air through the exhaust passage 212. As an alternative, the intake passage 211 and the exhaust passage 212 can be arranged at the same height. As an alternative, the exhaust passage 212 can also be arranged above the intake passage 211.

[0050] Optionally, the generator unit further includes a temperature sensor for monitoring the temperature inside the generator 2. Specifically, the temperature sensor can be arranged inside the intake passage 211, the exhaust passage 212 or the generator housing 21.

[0051] Further optionally, as Figure 1 shown, the generator unit further includes a flow valve 5 arranged on the pipeline where the second output end 32 of the air filter 3 communicates with the intake passage 211. Specifically, the opening degree of the flow valve 5 is adjusted according to the temperature value monitored by the temperature sensor so as to accurately cool the generator 2. It can be understood that the larger the temperature value monitored by the temperature sensor, the larger the opening degree of the flow valve 5.

[0052] Specifically, for a vehicle, both the temperature sensor and the flow valve 5 are electrically connected to the vehicle controller. The vehicle controller adjusts the opening degree of the flow valve 5 according to the temperature value monitored by the temperature sensor so as to accurately cool the generator 2.

[0053] Optionally, as Figure 1 shown, a check valve 6 is arranged on the pipeline where the exhaust passage 212 communicates with the outside. This can prevent the outside air from flowing back into the generator 2. Thus, dust, debris, etc. can be completely prevented from entering the generator 2.

[0054] Among them, the specific structures of the engine 1, the generator 2 and the air filter 3 all belong to the prior art and will not be elaborated here.

[0055] The present utility model also discloses a vehicle including the above-mentioned generator unit. By adopting the above-mentioned generator unit, the production cost can be effectively reduced, the assembly efficiency can be improved, and the working performance of the vehicle can be enhanced.

[0056] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
