As shown in fig. 1, the present invention discloses a regenerative braking device 10 based on air pressure potential energy, which includes: an input mechanism 100, a synchronization coordination mechanism 200, and an energy recovery mechanism 300. The input mechanism 100 is in driving connection with an external target rotating shaft to be braked, and further drives the energy recovery mechanism 300 through the synchronous coordination mechanism 200, so as to recover the braking energy.
Specifically, as shown in fig. 2 and 3, the input mechanism 100 includes an input axle 110, and an input shaft gear 120 is provided on the input axle 110.
As shown in fig. 2, the synchronization coordination mechanism 200 includes: synchronizer 400, driven friction wheel 210, and coordinating counterweight 220. As shown in fig. 2 and 3, the synchronizer 400 is installed at the input shaft gear 120 of the input shaft 110, the driven friction wheel 210 is fixedly connected to the input shaft 110, and the coordinating weight block 220 is disposed on the driven friction wheel 210.
As shown in fig. 1, the energy recovery mechanism 300 is drivingly connected to the synchronization coordination mechanism 200. As shown in fig. 2, the energy recovery mechanism 300 includes an actuating piston assembly 310 and a cylinder body 320, a piston cavity 321 is formed in the cylinder body 320 and is used in cooperation with the actuating piston assembly 310, an air inlet 322 and an air outlet 323 which are communicated with the piston cavity 321 are formed in the cylinder body 320, one-way air valves (not shown) are respectively disposed at the air inlet 322 and the air outlet 323, the one-way air valves enable air in the cylinder body 320 to flow only along a specified path, and the air is pushed by the actuating piston assembly 310 to pass through the air outlet 323 and be continuously pressed into an external air storage cylinder.

In this embodiment, as shown in fig. 4 and 5, the synchronous sleeve 410 is provided with an annular trigger groove 413. As shown in FIG. 6, the synchronization coordinating mechanism 200 further includes a lever 500, and the lever 500 is drivingly connected to the synchronization sleeve 410 through the annular trigger groove 413. Preferably, as shown in fig. 6, one end of the operating lever 500 is received in the annular triggering groove 413 and pressed against a groove wall of the annular triggering groove 413, so that the movement of the operating lever 500 controls the movement of the synchronizing sleeve 410.
Preferably, as shown in fig. 4, the number of the auxiliary sliders 420 is plural, and the plural auxiliary sliders 420 are distributed in an annular array centered on the center line of the input hub 110. And the synchronizer 400 further includes a supporting elastic member 440, and the supporting elastic member 440 is used to provide a supporting elastic force to the plurality of auxiliary sliders 420.
The operation of the regenerative braking device 10 based on the air pressure potential energy will be explained with reference to the present embodiment:
when the vehicle is normally running, as shown in fig. 5, the rotational speed of the input mechanism 100 and the synchronizer 400 is the same as that of the external target rotating shaft, but the rotational speeds of the driven friction wheel 210 and the coordinating weight 220 are zero;
during the braking process of the vehicle, as shown in fig. 6 and 7, the synchronous coordination mechanism 200 performs two synchronization steps, so that the rotation speed of the driven friction wheel 210 and the coordination weight 220 is consistent with the rotation speed of the input mechanism 100, drives the energy recovery mechanism 300 to operate, and injects compressed air into the external air storage cylinder. During the process of compressing air by the energy recovery mechanism 300, reverse resistance is generated to hinder the movement of the actuating piston assembly 310, so that a reverse blocking torque is provided for the input mechanism 100 through the synchronous coordination mechanism 200, and finally the purpose of braking and decelerating is achieved;
the specific process of the synchronization coordination mechanism 200 for two times is as follows:
when the vehicle starts to brake, i.e. the first synchronization, as shown in fig. 6, the driver controls the lever 500 to move in the direction of the arrow shown in the figure by means of the vehicle brake system, and the synchronization sleeve 410 will also move in the direction of the arrow shown in the figure due to the engagement of the annular trigger groove 413 with the lever 500. Since the thrust slot 411 is engaged with the auxiliary slider 420, the synchronizing sleeve 410 pushes the auxiliary slider 420 to move in the same direction through the thrust slot 411, and further, the synchronizing ring 430 is pushed by the auxiliary slider 420 to be pressed against the driven pulley 210. At this time, friction exists between the synchronizing ring 430 and the driven friction wheel 210, the driven friction wheel 210 and the coordinating counterweight block 220 start to rotate under the driving of the synchronizing ring 430, and at the same time, the actuating connecting rod 312 connected with the coordinating counterweight block 220 also drives the piston head 311 to slide in the piston cavity 321, so as to achieve the purpose of converting the kinetic energy of vehicle braking into the air pressure potential energy of air compression. However, if the rotational speed of the driven friction wheel 210 is not stable and does not match the rotational speed of the input mechanism 100 only by the action of frictional force after the first synchronization, the efficiency of the energy recovery mechanism 300 is not stable;
after the first synchronization is completed, the synchronization coordination mechanism 200 begins a second synchronization as the vehicle brakes are applied. As shown in fig. 7, the operating rod 500 and the synchronizing sleeve 410 continue to move in the direction of the arrow, and the auxiliary slider 420 also tends to move because the thrust slot 411 is engaged with the auxiliary slider 420, but due to the blocking of the synchronizing ring 430, the guiding inclined surface 421 of the auxiliary slider 420 slides downwards along the inclined surface slot wall 412, i.e., the auxiliary slider 420 moves in the direction of the arrow, so as to perform a back-off action, thereby providing a forward space for further movement of the synchronizing sleeve 410. Subsequently, the synchronizing sleeve 410 will move into engagement with the driven friction wheel 210, at which point the speed of rotation of the driven friction wheel 210 will coincide with the speed of rotation of the input mechanism 100, i.e. a second synchronization is completed. After the second synchronization, the actuating link 312 can obtain a stable driving force for driving the piston head 311 to slide back and forth, i.e., the energy recovery mechanism 300 can obtain stable efficiency;
after the synchronous coordination mechanism 200 is synchronized twice, the actuating piston assembly 310 will obtain a stable driving force, and correspondingly, the resistance generated by the gas compressed by the actuating piston assembly 310 will also be stably transmitted to the input mechanism 100, so that the input wheel shaft 110 obtains a stable reverse torque, and finally the purpose of braking the vehicle is achieved;
after braking is completed, the reset of the operating lever 500 drives the synchronous sleeve 410 to move reversely, the auxiliary sliding block 420 is reset under the elastic force of the supporting elastic member 440 and moves reversely along with the synchronous sleeve 410, and simultaneously, the synchronous ring 430 is pulled by the auxiliary sliding block 420 to be disengaged from the driven friction wheel 210.
It is emphasized that a regenerative braking device 10 based on air pressure potential of the present invention has the following advantages: firstly, when the vehicle is braked, the compressed air pressure potential energy of part of kinetic energy gas of the vehicle brake is utilized, thereby realizing energy recovery; secondly, partial kinetic energy of vehicle braking is converted into air pressure potential energy of air compression, heat production of a braking system can be reduced, loss of the system and parts is reduced, and the service life of the braking system is prolonged; thirdly, the regenerative braking device 10 based on air pressure potential energy can enable the kinetic energy of the vehicle to be converted more quickly during braking, thereby shortening the braking distance of the vehicle and improving the safety of the vehicle.
In one embodiment, as shown in FIG. 4, the driven friction wheel 210 is attached to the input shaft 110 by a retaining ring 230, which makes the connection of the driven friction wheel 210 to the input shaft 110 more stable.
To sum up, the utility model discloses a regenerative braking device 10 based on atmospheric pressure potential energy can retrieve braking energy in the vehicle braking, has realized the recovery of energy and has recycled.
