SUMMARY

[0004] The present application aims to provide a wind resistance type multi-stator permanent magnet generator to solve the problem of the increasing requirements for environmental protection and energy saving of automobiles with the development of technology, and the existing generator structure cannot meet the user's use requirements.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical scheme:

[0006] A wind resistance type multi-stator permanent magnet generator comprises:

[0007] A motor body, an input shaft and a transmission device, one end of the motor body is fixedly provided with a front end cover, and the other end of the motor body away from the front end cover is fixedly provided with a rear end cover. The front end cover and the rear end cover away from the motor body are provided with shaft holes, threaded holes and heat dissipation holes. The input shaft penetrates the motor body and is in transmission connection with the motor body through a shaft coupling.

[0008] Preferably, the transmission device is a fan, and the first input shaft is fixedly connected with the fan through the shaft holes of the front end cover and the rear end cover.

[0009] Preferably, the second input shaft passes through the shaft hole of the front end cover and is fixedly connected with a gear, and a planetary gear mechanism is arranged between the motor body stator and the front end cover, the planetary gear mechanism comprising planetary gears, a planet carrier and a ring gear, the gear being located at the center of the plurality of planetary gears and being engaged with the plurality of planetary gears.

[0010] Preferably, the transmission device comprises a sector gear, a support rod, a support frame and a stand, the support rod being fixedly connected with the front end cover, the top of the support rod being fixedly connected with the lower end surfaces of the four corners of the support frame, the upper end surfaces of the four corners of the support frame being fixedly connected with the bottom of the stand, the top of the stand being fixedly connected with the sector gear through a bearing, and the gear being engaged with the sector gear.

[0017] Compared with the prior art, the application has the following beneficial effects:

[0018] The difference between the application and the existing generator is that the conventional vehicle generator utilizes a fuel engine to provide power, the generated electric energy is used to supply various electric systems of the vehicle body and charge the storage battery, and a voltage stabilizing and current limiting protection is needed to prevent the charging voltage from being too high and damaging the electric system; however, the application utilizes the wind resistance thrust of the front bumper of the vehicle to generate electricity, that is, the wind energy is recovered and enhanced through the wind inlets of the front bumper to generate electricity, the wind energy is recovered by the wind resistance generator driven by the electric energy to form wind, the recovered electric energy is only the electric energy converted from the wind energy recovered by the wind inlets and the grating of the front bumper, is part of the wind energy for driving the vehicle to form wind, and is not enough for the electric system of the vehicle body. Therefore, the wind resistance generator does not need voltage stabilizing and current limiting protection, and can recover the electric energy to the maximum extent.

[0019] (1) The wind resistance generator is installed behind the front bumper, and is specially used to recover the wind resistance pushing force of the front bumper to drive the wind resistance generator to generate electricity. The wind resistance generator not only shares the wind resistance of the front bumper, but also recovers the electricity generated by the wind resistance pushing force, without increasing the driving wind resistance of the original vehicle.

[0020] (2) When the wind resistance generator generates electricity, the increased wind resistance ensures the safe and stable driving of the vehicle, thereby obtaining the free "safe energy consumption" compensation provided by the total power supply. At the same time, the electricity recovered by the wind resistance generator is also a re-recovery of the "safe energy consumption".

[0021] (3) When the pure electric vehicle is in medium and high speed, the wind resistance generator can continuously recover electricity, slow down the consumption of the battery, and the recovered electricity is higher than the electricity recovered by the KERS brake kinetic energy recovery system currently used by the vehicle.

[0022] (4) The wind resistance generator installed in the pure electric vehicle recovers the wind energy, realizes the energy recycling of the "battery-drive motor-wind resistance generator-battery" wind energy recovery system, and further increases the endurance mileage of the pure electric vehicle.

DETAILED DESCRIPTION

[0030] With reference to the drawings and embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0031] Embodiment one: Figure 1 Figure 2 A wind resistance type multi-stator permanent magnet generator (referred to as a wind resistance generator) is shown. The motor body 1 is a prior art, which will not be described in detail here. The front end cover 2 and the rear end cover 3 are located at both ends of the motor body 1. The front end cover 2 and the rear end cover 3 are provided with cooling holes 4, threaded holes 5, and shaft holes 6. Four threaded holes 5 are evenly arranged along the outer edge circumference of the front end cover 2 and the rear end cover 3. Shaft holes 6 are arranged at the center of the front end cover 2 and the rear end cover 3. A plurality of cooling holes 4 are arranged between the threaded holes 5 and the shaft holes 6. The transmission device is a fan 8. The first input shaft 7 passes through the shaft holes 6 of the front end cover 2 and the rear end cover 3 and is fixedly connected with the fan 8. When the vehicle moves forward, the wind resistance drives the fan 8 to rotate, thereby driving the first input shaft 7 to rotate and generating electricity. The fans 8 on both sides drive the first input shaft 7 to rotate, which can provide more power. Since the fans 8 are placed in front and back, the wind blown from the cooling holes 4 of the front end cover 2 can discharge the heat generated by the motor from the cooling holes 4 of the rear end cover 3, thereby accelerating the heat dissipation.

[0032] Embodiment two: Figure 3 Figure 4 The content is the same as that of the first embodiment, and the difference is that the second input shaft 94 passes through the shaft hole 6 of the front end cover 2 and is fixedly connected with the gear 10. The motor body 1 is provided with a planetary gear mechanism 9 between the stator and the front end cover 2. The planetary gear mechanism 9 includes planetary gears 91, a planet carrier 92, and a ring gear 93. The gear 10 is located at the center of the plurality of planetary gears 91 and is engaged with the plurality of planetary gears 91. The planetary gear mechanism 9 is a prior art, which will not be described in detail here. The function is to increase the rotation speed of the generator. The four planetary gears 91 are evenly arranged in the circumferential direction. The gear 10 is located at the center of the four planetary gears 91 and is engaged with the four planetary gears 91. The fan 8 is sleeved on the second input shaft 94. The ring gear 93 is evenly provided with a plurality of threaded holes (not shown in the figure) along the outer edge circumference. The planetary gear mechanism 9 is fixedly connected between the motor stator and the front end cover 2 by bolts passing through the threaded holes 5.

[0033] Embodiment three: Figure 5 ​​As shown, the transmission comprises a fan gear 111, a support rod 112, a support 113, a column 114, the support rod 112 is fixedly connected with the front end cover 2, the top of the support rod 112 is fixedly connected with the lower end surface of the four corners of the support 113, the upper end surface of the four corners of the support 112 is fixedly connected with the bottom of the column 114, the top of the column 114 is fixedly connected with the fan gear 111 through a bearing, the gear 10 is engaged with the fan gear 111, a spring washer (not shown in the figure) is arranged between the support rod 112 and the threaded hole 5, which is used to prevent the support rod 112 from separating from the threaded hole 5 during high-speed rotation, the support 113 is a rectangular frame, the top of the support rod 112 is fixedly connected with the lower end surface of the four corners of the support 113, the upper end surface of the four corners of the support 113 is fixedly connected with the bottom of the column 114, the top of the column 114 is fixedly connected with the fan gear 111 through a bearing, the fan gear 111 is engaged with the gear 10, and the number of the fan gear 111 is preferably 2-4, which takes into account the performance and volume.

[0034] Specifically, the fan gear 111 comprises a fan blade 1111 and a fan gear tooth 1112, the top end of the support rod 112 is sleeved with the fan 8 through a bearing, the outer side of the fan blade 1111 is provided with the fan gear tooth 1112 (this fixing mode is the existing technology in the industry, so it is not represented), and the fan blade 1111 and the fan gear tooth 1112 at the end of the fan blade are integrally formed at one time, which is used to push the fan gear 111 to rotate by using the wind resistance when the vehicle moves forward, so as to drive the motor to generate electricity by rotating the second input shaft 94.

[0035] Embodiment four: as Figure 6 shown, the fan 8 is a series integrated multi-fan blade structure, the front end of the fan 8 is close to the air inlet of the front bumper of the vehicle, the diameter of the fan is slightly larger, according to the principle of wind channel wind collection and wind energy enhancement, the diameter of the fan gradually becomes smaller to the right, which is better matched with the wind channel to recover more wind energy, and the rear end of the fan 8 is a multi-stator series permanent magnet generator, which cooperates with the fan 8 to recover more wind energy in a small space in multiple levels.

[0036] As can be seen from the above: in order to save materials, the permanent magnet generator is series connected to form a multi-stator permanent magnet generator, similarly, the fan blades of the wind resistance generator can also be series connected together to form a series integrated fan structure, the fan blades can be fixed on the extended shaft protruding from the center of the front end cover of the wind resistance generator, or can be connected through a universal joint transmission and fixed on the central rotating shaft of the front end cover of the wind resistance generator, in this way, the wind resistance generator can reasonably concentrate the use of wind energy in a small space and multiple levels, reduce the indirect loss of wind energy transmission, and reduce the manufacturing cost.

[0037] Implementation principle:

[0038] According to the common sense that the vehicle movement forms wind, the pure electric vehicle needs to consume electric energy to drive the vehicle movement to form wind; similarly, we can also reasonably use the wind energy formed in the vehicle movement to drive the wind resistance generator to rotate and generate electricity to recover electric energy, through the above-mentioned cycle of electric energy to wind energy and wind energy to electric energy, to form the recycling of part of the electric energy of the vehicle, to achieve the purpose of energy saving and increasing the cruising range. According to the electric energy conversion efficiency of the generator, in the energy conversion process, the generator has friction and heat loss, etc., and can only recover most of the electric energy, and the practical significance is not ideal. Therefore, we create conditions: install the wind resistance generator behind the front bumper of the vehicle, and specially use the bumper wind resistance pushing force of the front bumper air inlet and grille to drive the wind resistance generator to generate electricity; both share the front bumper wind resistance, and will not increase the original vehicle running wind resistance; at the same time, when the wind resistance generator generates electricity, the increased wind resistance guarantees the safe and stable driving of the vehicle, so as to obtain the free "safety energy consumption" compensation provided by the total power supply, so the electric energy recovered by the wind resistance generator is also the recycling of the free "safety energy consumption" provided by the total power supply. Therefore, we use the wind resistance generator to achieve the purpose of recycling the free "safety energy consumption", which reflects the practical value of the application.

[0039] Although embodiments of the application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the application, and the scope of the application is defined by the appended claims and their equivalents.
