Description

Technical Field

[0001] This application relates to the field of generator heat dissipation technology, specifically to a generator, and also to a vehicle including the aforementioned generator. Background Technology

[0002] To achieve heat dissipation, generators typically have internal cooling ducts. A cooling fan draws air in from the rear and exhausts it from the front, achieving air cooling and lowering the internal temperature. Generators have a wide range of applications. When used in equipment that operates in harsh environments, such as harvesters, a large amount of debris, dust, and other impurities are generated during operation. During generator operation, these impurities can easily adhere to and even block the rear air intake, leading to poor heat dissipation and, in severe cases, overheating and failure.

[0003] To address the issue of clogged cooling ducts, generators employ a brush structure to clean debris, dust, and other contaminants from the rear end, achieving self-cleaning. However, in existing generator structures, the brush holder of the brush structure is bolted to the generator's rotor shaft, and the rotation of the rotor shaft drives the brush structure to rotate.

[0004] However, this method requires high precision in the assembly and machining of the rotor shaft and brush holder. If there is any eccentricity between the two, the rotor shaft is more likely to break. In addition, due to the high speed of the rotor shaft, the rotating structure connecting the rotor shaft and brush holder is more likely to cause the output end of the rotor shaft to wear round after working for a long time, which affects the power input to the brush structure and thus affects the heat dissipation of the generator. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a generator that reduces the occurrence of rotor shaft breakage while ensuring the heat dissipation effect of the generator.

[0006] The purpose of this application is also to provide a vehicle including the above-mentioned generator, so as to reduce the occurrence of generator rotor shaft breakage and improve the operational reliability of the generator brush structure.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] A generator, comprising:

[0009] The generator body includes a generator housing and a rotor shaft disposed within the generator housing, and the generator housing is provided with heat dissipation holes;

[0010] A cooling fan is used to ventilate the heat dissipation holes, and the cooling fan is mounted on the rotor shaft;

[0011] The cleaning structure is capable of performing cleaning actions to clean the heat dissipation holes;

[0012] The cleaning fan is driven to rotate by the airflow of the cooling fan to drive the cleaning structure to perform the cleaning action, and the cleaning fan is connected to the cleaning structure.

[0013] Preferably, in the above-mentioned generator, both the cleaning fan and the cleaning structure are located on the air intake side of the cooling fan.

[0014] Preferably, in the generator described above, the heat dissipation hole includes an air inlet and an air outlet, and the cleaning fan and the cleaning structure are both located on the air inlet side of the air inlet.

[0015] Preferably, in the above-mentioned generator, the generator housing includes a front cover and a rear cover, and the input end of the rotor shaft extends out of the front cover;

[0016] The air inlet is located on the rear end cover, and the air outlet is located on the front end cover;

[0017] The cleaning fan is rotatably disposed on the outside of the rear end cover, and the cleaning structure is disposed on the outside of the rear end cover.

[0018] Preferably, in the above-mentioned generator, the cleaning structure is rotatably mounted on the rear end cover, and the cleaning structure performs the cleaning action by rotating;

[0019] The cleaning fan is collinear with the rotation axis of the cleaning structure.

[0020] Preferably, in the above-mentioned generator, a rotatable cleaning shaft is provided on the rear end cover, and both the cleaning fan and the cleaning structure are disposed on the cleaning shaft;

[0021] The cleaning shaft is coaxial with or parallel to the rotor shaft.

[0022] Preferably, in the above-mentioned generator, the cleaning shaft and the rear end cover are rotatably coupled via a cleaning bearing;

[0023] The rear end cover is provided with a mounting cavity for installing the cleaning bearing.

[0024] Preferably, in the above-described generator, the cleaning fan and the cleaning structure are arranged axially along the generator housing; or the cleaning structure is integrated onto the cleaning fan.

[0025] As can be seen from the above technical solution, the generator provided in this application includes a generator body, which includes a generator housing and a rotor shaft disposed within the generator housing. The generator housing is provided with heat dissipation holes. A cooling fan is used to ventilate the heat dissipation holes and is disposed on the rotor shaft. A cleaning structure is capable of performing a cleaning action to clean the heat dissipation holes. A cleaning fan is driven to rotate by the airflow of the cooling fan to drive the cleaning structure to perform a cleaning action, and the cleaning fan is connected to the cleaning structure.

[0026] When the generator provided in this application is used, the rotor shaft of the generator body rotates together with the cooling fan, so that the heat dissipation holes on the engine housing can be ventilated at the same time to generate electricity and dissipate heat. The air force generated by the rotation of the cooling fan drives the cleaning fan to rotate, and the rotation of the cleaning fan drives the cleaning structure to perform cleaning action to clean the heat dissipation holes and prevent the generator's cooling air duct from being blocked.

[0027] Therefore, the cleaning structure of the generator provided in this application embodiment is driven independently by a cleaning fan outside the generator body. The cleaning structure is separate from the rotor shaft of the generator body and works independently. The rotor shaft of the generator body does not need to input power to the cleaning structure, so there is no need for a connection between the rotor shaft and the cleaning structure, reducing the requirements for assembly and machining precision. The rotor shaft will not break due to eccentricity between the two, thus reducing the possibility of rotor shaft breakage. In addition, the rotation of the cleaning fan is driven by the wind force generated by the rotation of the cooling fan, which does not require synchronization with the rotor shaft speed. The wind force generated by the rotation of the cooling fan makes the speed of the cleaning fan relatively low, which can reduce the power input wear between the cleaning fan and the cleaning structure and avoid the possibility that the cleaning structure will lose its self-cleaning function because it cannot rotate with the cleaning fan. This improves the working reliability of the cleaning structure, thereby ensuring the heat dissipation effect of the generator and increasing the service life of the generator.

[0028] This application also provides a vehicle, including a walking device and a power device for driving the walking device to walk; it also includes a generator connected to the power device or the rotating shaft of the walking device, wherein the generator is any of the above-mentioned generators. Since the above-mentioned generators have the above-mentioned effects, vehicles with the above-mentioned generators have the same effects, so they will not be described in detail here.

[0029] Preferably, the vehicle is a harvester or combine harvester. Attached Figure Description

[0035] This application provides a generator and a vehicle that can reduce the occurrence of generator rotor shaft breakage while ensuring the generator's heat dissipation effect.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] like Figure 1-2 As shown, the generator provided in this embodiment includes a generator body, which includes a generator housing and a rotor shaft 9 disposed within the generator housing. The generator housing is provided with heat dissipation holes. A cooling fan (not shown in the figure) is used to ventilate the heat dissipation holes and is disposed on the rotor shaft 9. A cleaning structure 2 is capable of performing a cleaning action to clean the heat dissipation holes. A cleaning fan 1 is driven to rotate by the airflow of the cooling fan to drive the cleaning structure 2 to perform a cleaning action. The cleaning fan 1 is connected to the cleaning structure 2.

[0038] When the generator provided in this application embodiment is used, the rotor shaft 9 of the generator body rotates together with the cooling fan, so that the heat dissipation holes on the engine housing are ventilated at the same time as generating electricity, and the heat dissipation holes are used for heat dissipation; and the wind force generated by the rotation of the cooling fan drives the cleaning fan 1 to rotate, and the rotation of the cleaning fan 1 drives the cleaning structure 2 to perform cleaning action to clean the heat dissipation holes and prevent the generator's heat dissipation air duct from being blocked.

[0039] Therefore, the cleaning structure 2 of the generator provided in this embodiment is driven solely by the cleaning fan 1 outside the generator body. The cleaning structure 2 is separate from the rotor shaft 9 of the generator body and works independently. The rotor shaft 9 of the generator body does not need to input power to the cleaning structure 2, so there is no need for connection between the rotor shaft 9 and the cleaning structure 2, reducing the requirements for assembly and machining precision. The rotor shaft 9 will not break due to eccentricity, thus reducing the possibility of rotor shaft 9 breaking. In addition, the rotation of the cleaning fan 1 is driven by the wind force generated by the rotation of the cooling fan, without the need to synchronize the rotation speed of the rotor shaft 9. The wind force generated by the rotation of the cooling fan makes the rotation speed of the cleaning fan 1 lower, which can reduce the wear of power input between the cleaning fan 1 and the cleaning structure 2, and avoid the possibility that the cleaning structure 2 will lose its self-cleaning function because it cannot rotate with the cleaning fan 1. This improves the working reliability of the cleaning structure 2, thereby ensuring the heat dissipation effect of the generator and increasing the service life of the generator.

[0040] It should be noted that, in order to ensure that the airflow generated by the cooling fan drives the cleaning fan 1 to rotate, the appropriate configuration of the cleaning fan 1 should be selected based on the airflow generated by the cooling fan at the lowest speed of the rotor shaft 9.

[0041] Preferably, both the cleaning fan 1 and the cleaning structure 2 are located on the air intake side of the cooling fan. Since the cleaning structure 2 is connected to the cleaning fan 1, they are located on the same side of the cooling fan. When the cleaning fan 1 rotates, it drives the cleaning structure 2 to clean the heat dissipation holes at the air intake position of the generator housing, achieving self-cleaning of the air intake. Because the suction force generated on the air intake side of the cooling fan is relatively large, it can increase the rotation speed of the cleaning fan 1, thereby improving the cleaning effect of the cleaning structure 2. Alternatively, the cleaning fan 1 can also be located on the air outlet side of the cooling fan, using the blowing force of the cooling fan to drive the cleaning fan 1 to rotate, thereby driving the cleaning structure 2 to clean the heat dissipation holes at the air outlet position of the generator housing.

[0042] It is understandable that the cooling fan can be located on the air intake side of the generator body or on the air exhaust side of the generator body, as long as it can drive the cooling holes to enter and exit the air. This application will not elaborate on this point.

[0043] In the generator provided in this embodiment, the heat dissipation holes include air inlet holes and air outlet holes. With the rotor shaft 9 driving the cooling fan to rotate, air enters the generator housing through the air inlet holes. After heat exchange through the heat dissipation channels of the generator housing, the air exits through the air outlet holes, thereby reducing the internal temperature of the generator and extending its service life.

[0044] To improve the rotational responsiveness of the cleaning fan 1, both the cleaning fan 1 and the cleaning structure 2 are positioned on the air intake side of the air inlet. In this configuration, the cleaning fan 1 is located outside the generator housing, and the air intake side of the air inlet has a larger space, more air, and stronger suction, which facilitates the rotation of the cleaning fan 1. Alternatively, the cleaning fan 1 can also be positioned between the air outlet side of the air inlet and the air intake side of the cooling fan to generate suction.

[0045] Specifically, the heat dissipation holes are formed by perforated structures or ventilation meshes on the generator housing, and this application does not make specific limitations here.

[0046] In a specific embodiment, the generator housing includes a front cover 6 and a rear cover 3, with the input end of the rotor shaft 9 extending out of the front cover 6. An air inlet is located on the rear cover 3, and an air outlet is located on the front cover 6. A cleaning fan 1 is rotatably mounted on the outside of the rear cover 3, and a cleaning structure 2 is also mounted on the outside of the rear cover 3. In application, the input end of the generator's rotor shaft 9 is connected to the vehicle's wheel system or other rotating power unit via a belt drive mechanism formed by a pulley 7 and a transmission belt, or other transmission mechanisms, thereby driving the rotor shaft 9 to rotate and, in conjunction with the stator 5 of the generator body, generating electricity.

[0047] In this embodiment, the air intake is formed by the heat dissipation holes on the rear cover 3, and the air outlet is formed by the heat dissipation holes on the front cover 6. The rear cover 3 is not connected to any other structures, and the outer space is large, resulting in a larger air intake and improved heat dissipation. It also facilitates the layout and cleaning of the fan 1. Moreover, the generator's heat dissipation method is rear-end air intake and front-end air exhaust. The rear cover 3 has a cleaning structure 2. Utilizing the rear-end air intake characteristic when the generator is working, the air drawn by the cooling fan causes the cleaning fan 1 to rotate, thereby driving the cleaning structure 2 to perform a cleaning action, effectively cleaning debris, dust, and other impurities at the rear end, achieving a self-cleaning effect for the air intake, and ensuring the generator's heat dissipation effect.

[0048] This application also allows the air inlet and outlet to be located in other positions on the generator housing, as long as heat dissipation inside the generator can be achieved. The positions of the cleaning fan 1 and the cleaning structure 2 can be adjusted accordingly.

[0049] like Figure 1As shown, the generator housing includes a front cover 6, a middle shell 4, and a rear cover 3 arranged sequentially from the input end to the other end of the rotor shaft 9. The front cover 6 and the middle shell 4 cooperate to form a working cavity for mounting the rotor shaft 9 and the stator 5. The other end of the rotor shaft 9 extends out of the middle shell 4. The rotor shaft 9 is rotatably engaged with the front cover 6 via a front bearing 8 and with the middle shell 4 via a rear bearing 10. The middle shell 4 and the rear cover 3 cooperate to form an air intake channel communicating with the heat dissipation holes. The cleaning fan 1 and the cleaning structure 2 are both located on the outside of the rear cover 3, i.e., behind the rear cover 3. The generator housing is formed by connecting the front cover 6, the middle shell 4, and the rear cover 3, facilitating the disassembly and assembly of the internal structure.

[0050] Preferably, in the above-mentioned generator, the cleaning structure 2 is rotatably mounted on the rear end cover 3, and the cleaning structure 2 performs the cleaning action by rotating. This embodiment focuses on the circumferential arrangement of the heat dissipation holes; when the generator is working, the cleaning fan 1 drives the cleaning structure 2 to rotate, thereby achieving dust removal and cleaning of the heat dissipation holes, and also has a certain cleaning effect on weeds and dust at the rear end of the generator, thus improving the service life of the generator. Of course, depending on the actual working scenario, the heat dissipation holes can also be set off to one side of the axis, or set on the side of the generator housing, etc., and this application does not make specific limitations in this regard. The cleaning structure 2 can also perform the cleaning action by moving, and this application does not make specific limitations in this regard.

[0051] To simplify the structure, the rotation axes of the cleaning fan 1 and the cleaning structure 2 are collinear. The cleaning fan 1 and the cleaning structure 2 occupy the same axial position, which facilitates layout and reduces the impact on the heat dissipation airflow, ensuring effective heat dissipation. Of course, the rotation axes of the cleaning fan 1 and the cleaning structure 2 can also be parallel or perpendicular; this application does not impose specific limitations on this.

[0052] The cleaning fan 1 and the cleaning structure 2 can be directly connected or connected through a transmission mechanism, as long as the cleaning fan 1 drives the cleaning structure 2 to rotate.

[0053] Specifically, the cleaning fan 1 includes multiple fan blades arranged circumferentially; the cleaning structure 2 is a brush structure set outside the rear cover 3, including a brush holder and a cleaning brush set on the brush holder. The brush holder is connected to the cleaning fan 1, and the cleaning fan 1 drives the brush holder to rotate, thereby driving the cleaning brush to clean the heat dissipation holes.

[0054] The blades of the cleaning fan 1 can be offset or aligned circumferentially with the brush holder arm. The relationship between the outer diameter of the blades and the outer diameter of the brush holder arm is not specifically limited; the cleaning fan 1 only needs to be able to drive the cleaning brush to rotate. The blades can be straight-blade, curved-blade, or airfoil-shaped. The configuration of the brush holder, cleaning brush, and the number and shape of the blades are determined based on the airflow generated by the cooling fan at its lowest rotational speed on the rotor shaft 9. The goal is simply to ensure that the cooling fan's airflow drives the cleaning fan 1 to rotate along with the cleaning structure 2.

[0055] For ease of assembly, a rotatable cleaning shaft is provided on the rear cover 3, and both the cleaning fan 1 and the cleaning structure 2 are mounted on the cleaning shaft. In this embodiment, the cleaning fan 1 and the cleaning structure 2 are fixed on the same shaft, which is simple in structure and easy to disassemble and assemble; the cleaning fan 1 and the cleaning structure 2 may also each include a shaft, and the shafts are then fixedly connected to each other.

[0056] In a further technical solution, the cleaning shaft and the rotor shaft 9 are coaxial or parallel, which facilitates the layout of the cleaning fan 1, the cleaning structure 2, and the rotor shaft 9. At the same time, when the cleaning shaft and the rotor shaft 9 are coaxial, the cleaning fan 1, the cleaning structure 2, and the rotor shaft 9 are arranged along the same axis, which reduces the impact on the heat dissipation airflow and ensures the heat dissipation effect. In addition, the cleaning fan 1 is arranged at the position of the heat dissipation fan with the greatest suction force on the rotor shaft 9, which is more conducive to the cleaning fan 1 being driven to rotate, thereby driving the cleaning structure 2 to rotate and achieve the cleaning function.

[0057] To improve rotational stability, the cleaning shaft and the rear end cover 3 are rotatably connected via a cleaning bearing 11; the rear end cover 3 is provided with a mounting cavity for installing the cleaning bearing 11. In this embodiment, the cleaning shaft is connected to the rear end cover 3 via the cleaning bearing 11, which provides rotational support, ensuring that the cleaning shaft can drive the cleaning fan 1 and the cleaning structure 2 to rotate simultaneously relative to the rear end cover 3.

[0058] Meanwhile, the cleaning bearing 11 is fixedly supported by the mounting cavity of the rear end cover 3, which facilitates the installation and fixation of the cleaning bearing 11. During assembly, the cleaning bearing 11 is first placed in the mounting cavity and positioned by the mounting cavity. Then, the cleaning bearing 11 is fixed in the mounting cavity by the fixing structure on the rear end cover 3, such as the clamping plate that axially presses the cleaning bearing 11. This facilitates the installation of the cleaning bearing 11 and provides good fixing strength for the cleaning bearing 11.

[0059] In one specific embodiment, the cleaning fan 1 and the cleaning structure 2 are arranged axially along the generator housing; as shown... Figure 1As shown, the cleaning fan 1 is located at the rear end of the cleaning structure 2. The cleaning fan 1 can rotate with the wind, thereby driving the cleaning structure 2 to rotate together, realizing the self-cleaning of the heat dissipation holes of the rear cover 3. When the cleaning fan 1 is blown by the wind alone, the rotation response is better and the cleaning effect is better.

[0060] Specifically, the front end of the cleaning structure 2 is positioned by a stop block and the rear end cover 3, and the rear end of the cleaning structure 2 is positioned by a gasket to the cleaning fan 1. The axial distance between the two is between 2-5mm or other values.

[0061] In another specific embodiment, the cleaning structure 2 is integrated into the cleaning fan 1. For example... Figure 2 As shown, in this embodiment, the brush holder of the cleaning structure 2 is made into a fan structure, which can also be regarded as integrating the cleaning brush into the cleaning fan 1. The air drawn by the cooling fan directly acts on the brush holder to make it rotate, which drives the cleaning brush of the cleaning structure 2 to rotate, thereby achieving the cleaning function. The structure of the cleaning structure 2 and the cleaning fan 1 integrated together is more convenient to assemble.

[0062] This application also provides a vehicle, including a walking device and a power device for driving the walking device; it also includes a generator connected to the rotating shaft of the power device or the walking device, the generator being the generator provided in any of the above embodiments; it reduces the possibility of breakage of the generator rotor shaft 9, while ensuring the heat dissipation effect of the generator, the advantages of which are brought about by the generator, please refer to the relevant parts in the above embodiments for details, which will not be repeated here.

[0063] When the vehicle is working, the rotor shaft 9 of the generator body is driven to rotate by the rotating shaft of the power unit or the walking device, thereby generating electricity; the rotor shaft 9 rotates together with the cooling fan to realize ventilation of the cooling holes on the engine housing and to dissipate heat through the cooling holes; and the wind force generated by the rotation of the cooling fan drives the cleaning fan 1 to rotate, and the rotation of the cleaning fan 1 drives the cleaning structure 2 to perform cleaning action to clean the cooling holes, thereby achieving dust removal and cleaning of the cooling holes and improving the service life of the generator.

[0064] Specifically, the rotating shaft of the power unit or the traveling device is connected to the rotor shaft 9 of the generator body via a belt drive mechanism or other transmission mechanism formed by pulleys 7 and a transmission belt, thereby driving the generator to generate electricity. The power unit can be an engine or other power structure, and the traveling device can be a structure such as wheels or tracks.

[0065] The vehicle in this application embodiment is a harvester or combine harvester. The working environment of harvesters or combine harvesters is relatively harsh, with a large amount of straw or other crop debris, which can easily enter the generator's cooling duct through the heat dissipation holes. The generator of this application uses a cleaning fan 1 driven by the wind power of the cooling fan to drive the cleaning structure 2 to clean the heat dissipation holes, prevent the generator's cooling duct from becoming blocked, thereby ensuring the generator's heat dissipation effect and improving the generator's service life.
