[0026] The core of the utility model lies in the energy recovery device to reduce the use cost of the vehicle with follow-up part.
[0027] Another purpose of the utility model is to provide a kind of vehicle comprising the energy recovery device described above.
[0028] In order to make the person in the art better understand the utility model scheme, the following referring to the drawings to the utility model embodiment is described, and in addition, the following shown embodiment does not have any limiting effect on the utility model content recited in claim.In addition, the constitution represented in the following embodiment is not limited to the solution scheme of the utility model recited in claim.
[0029] As Figure 1 And Figure 2 As shown in the utility model embodiment provided by the energy recovery device, it mainly includes rotating wheel 10, generator 30 and transmission member 40, wherein, rotating wheel 10 is used to bear the follow-up part 710 of vehicle, and directly contact with ground, in the process of vehicle movement, rotating wheel 10 will continuously rotate to drive follow-up part 710 displacement due to the friction with ground.Rotating wheel 10 is fixedly provided with follow-up wheel 20 in the circumferential direction, and follow-up wheel 20 synchronously rotates in the process of rotating wheel 10 rotation, to be used as the action component of energy recovery.And need to be explained, in order to make the movement of follow-up wheel 20 be regular concentric rotation movement, to ensure the stability and high efficiency of power transmission, follow-up wheel 20 and the center axis of rotating wheel 10 are arranged in line, to make follow-up wheel 20 can and rotating wheel 10 with same axis as rotating center realize rotation movement.
[0030] It should be noted that, in order to avoid the problem that the rotating wheel 10 bumps the follow wheel 20 during movement on the ground with some unevenness, and causes the energy recovery to fail, in the energy recovery device provided in the embodiment of the utility model, the size of the follow wheel 20 is smaller than the radius size of the rotating wheel 10, so as to provide a certain allowance for the contact height of the rotating wheel 10 with the ground, and when the rotating wheel 10 is sunk into the ground under some operating conditions, the follow wheel 20 with smaller radius can keep a distance from the ground, and keep smooth rotating movement to make the energy recovery process proceed smoothly.
[0031] Further, the structure matched with the rotating wheel 10 and the follow wheel 20 is the generator 30 and the transmission member 40, wherein the transmission member 40 is used to realize the transmission connection between the generator 30 and the follow wheel 20, so as to transmit the rotating movement energy of the follow wheel 20 to the generator 30, and recover the kinetic energy through the generator 30. Specifically, when the follow wheel 20 rotates under the driving of the rotating wheel 10, it directly drives the rotor in the generator 30 through the transmission of the transmission member 40, or drives the rotor in the generator 30 through the transmission structure, and the generator 30 converts the mechanical movement of the rotor into electric energy by using the electromagnetic induction principle. At the same time, the generator 30 is connected with the battery pack 60 through the transmission cable 50, so that the electric energy generated in the generator 30 can be transmitted to the battery pack 60 in time through the transmission cable 50, and the effective storage of electric energy is realized. The above-mentioned energy recovery device is based on the rotating wheel 10, has a compact structure, and cleverly utilizes the mechanical energy in the movement of the vehicle, and efficiently converts it into electric energy, so as to supplement the energy of the battery pack 60, thereby improving the utilization rate of energy, reducing the electric energy consumption of the vehicle, and further reducing the vehicle use cost.
[0032] Further, in order to improve the energy recovery efficiency of the energy recovery device, in some embodiments of the utility model, one follow wheel 20 is arranged on each side of the single rotating wheel 10 in the axial direction, so that the follow wheels 20 on both sides can simultaneously receive the power transmission from the rotating wheel 10 during the rotating process of the rotating wheel 10, and due to the symmetry of the follow wheels 20 on both sides, their stress is more balanced, which helps to improve the operation stability and reliability of the whole device, and improve the stability in the energy recovery process. Compared with the case that only one follow wheel 20 is arranged on one side, the structure of the double follow wheels 20 can significantly improve the energy recovery efficiency, the follow wheels 20 on both sides can simultaneously transmit mechanical energy to the subsequent power generation device, so that the generator 30 can obtain more mechanical energy and convert it into electric energy in unit time, thereby increasing the output of electric energy and improving the overall performance of the energy recovery device.
[0033] And on the basis of the above embodiment, for two follow-up wheels 20 symmetrically arranged on the single rotating wheel 10, they can be simultaneously connected with a generator 30 in transmission, to drive the power generation of a single generator 30, and the power of the two follow-up wheels 20 converges to a generator 30, so that the generator 30 can receive more mechanical power input, thereby generating more electric energy in unit time. Similarly, the two follow-up wheels 20 on the single rotating wheel 10 are respectively connected with a generator 30 in transmission, and the independent transmission configuration can present two sets of power generation systems. When one of the transmission chains fails or one of the generators 30 needs maintenance, the other transmission chain and generator 30 can still work normally, thereby improving the continuity of the entire energy recovery device. In addition, it should be noted that when the electric energy in the energy recovery device directly drives part of the structure of the vehicle, the independently arranged structure can also flexibly adjust the power output of each generator 30 according to actual needs, so as to adapt to different load conditions, so that the energy recovery device can maintain good operating state under various complex conditions.
[0034] Further, in the energy recovery device provided by the embodiment of the utility model, the radius of the follow-up wheel 20 is set to 1 / 3-1 / 2 of the radius size of the rotating wheel 10. Within the above range, the rotating wheel 10 has sufficient ground matching allowance, so that the follow-up wheel 20 can rotate stably without being affected by the ground condition, while maintaining the compactness of the rotating wheel 10 and the follow-up wheel 20, so as to facilitate the arrangement of the energy recovery device. From the perspective of mechanical energy transmission efficiency, appropriate radius ratio can reduce the loss of energy in the transmission process, and ensure that more mechanical energy is effectively transmitted to the generator 30 part.
[0035] Considering that the operation basis of the energy recovery device provided by the embodiment of the utility model is the rotating movement of the rotating wheel 10 relative to the ground, therefore, in some embodiments of the utility model, the outer ring wall surface of the rotating wheel 10 is also provided with anti-skid lines, which enhances the friction between the rotating wheel 10 and the ground, prevents the rotating wheel 10 from slipping due to wet ground or other reasons during the movement of the vehicle or other equipment, and ensures that the rotating wheel 10 can rotate stably, providing reliable mechanical energy input for the subsequent energy recovery process.
[0036] And it should be noted that the anti-skid lines can be arranged in various ways, such as pressing regular pattern on the surface of the rotating wheel 10, or pasting a layer of anti-skid material with high friction coefficient.
[0037] Further, for the transmission of the follow-up wheel 20 and the transmission member 40, in some embodiments of the utility model, the follow-up wheel 20 is a gear with protruding teeth on the outer periphery, and the transmission member 40 is a chain that meshes with the gear, the meshing of the protruding teeth on the gear and the chain is close and accurate, which can ensure the stability and accuracy of power transmission, and avoid the risk of relative sliding between the follow-up wheel 20 and the transmission member 40, so that the power can be efficiently transmitted to the generator 30, reducing the loss and fluctuation of energy in the transmission process, and ensuring the stable operation of the generator 30 and the stable generation of electric energy; secondly, the transmission structure of the gear and the chain has a large carrying capacity, which can adapt to the transmission demand of high torque, and the energy recovery device can ensure reliability and durability when facing large mechanical energy input.
[0038] And in some other embodiments of the utility model, the follow-up wheel 20 is a roller structure, and the transmission member 40 is a transmission belt in a tensioned state, the surface of the follow-up wheel 20 of the roller structure is smooth and cylindrical or slightly arc-shaped, which helps to reduce the friction loss and wear degree between the transmission belt, and prolong the service life of the transmission part. The transmission belt always maintains a proper tensioning state under the action of the tensioning device, so as to ensure that enough friction force can be generated between the roller and the transmission belt to transmit power. It should be noted that the transmission mode of the roller and the transmission belt has the characteristics of stable operation and low noise, so that the energy recovery device is more quiet and stable during operation, reducing the energy loss and mechanical failure risk caused by vibration or impact of the transmission part.
[0039] Further, as shown in Figure 3 The utility model discloses a kind of vehicles, the vehicle includes power part 720 and follow-up part 710, follow-up part 710 is contacted with ground and its position contacted with ground is provided with the energy recovery device of any one embodiment provided above, to drive generator 30 to generate electricity using the mechanical energy generated when follow-up part 710 is contacted with ground and rotates in the moving process of vehicle, convert mechanical energy into electric energy and store in battery pack 60. And it needs to be explained that, since the energy recovery device has the technical effect provided in any one embodiment above, the vehicle also has the technical effect provided in any one embodiment above, which will not be repeated here.
[0040] Further, in order to improve the stability of the energy recovery device during the movement of the follow-up part 710, in some embodiments of the utility model, a bearing platform is additionally arranged on the follow-up part 710 for bearing heavy objects according to operation requirements. When heavy objects are placed on the bearing platform, the weight of the heavy objects is transmitted to the rotating wheel 10 through the structure of the follow-up part 710, so that greater pressure is generated between the rotating wheel 10 and the ground, thereby increasing the friction between the two, significantly improving the grip performance of the rotating wheel 10 on the ground, preventing the rotating wheel 10 from slipping during vehicle driving, ensuring that the rotating wheel 10 can stably rotate, and further ensuring that the energy recovery device can continuously and effectively recover mechanical energy and convert it into electrical energy.
[0041] In addition, the presence of the bearing platform also increases the versatility of the vehicle to meet the needs of some special transportation or operation scenarios. For example, in a logistics distribution vehicle, the bearing platform can be used to place goods, and the weight of the goods can be used to optimize the energy recovery effect, while not affecting the transportation function of the goods, realizing the organic combination of energy recovery and goods transportation, and improving the overall use value and economic benefit of the vehicle.
[0042] Further, in the vehicle provided in the embodiments of the utility model, the battery pack 60 for receiving the energy generated by the energy recovery device can be independent of the follow-up part 710, that is, the battery pack 60 is specially used for storing the electrical energy generated by the energy recovery device, and a relatively independent energy recovery and storage system is formed. According to the power generation capacity of the energy recovery device and the actual use requirements, the capacity and specifications of the battery pack 60 can be flexibly configured, and are not limited by the power system of other parts of the vehicle. At the same time, the independent battery pack 60 is also convenient for maintenance, replacement and upgrading, and the reliability and maintainability of the entire energy recovery system are improved.
[0043] In other embodiments of the utility model, the battery pack 60 can also be the power supply battery pack 60 of the vehicle power part 720, that is, the electrical energy generated by the energy recovery device is directly supplemented into the power battery pack 60 of the vehicle, combined with the original power energy system of the vehicle, to directly improve the power reserve of the power battery pack 60 of the vehicle, and directly improve the use efficiency of the battery pack 60 of the vehicle.
