Description

Electric automobile capable of being automatically hydraulically charged during running

The technical field is as follows:

the utility model relates to an electric vehicle, especially vehicle are when going, along with the rotation of wheel, because the pressure effect that the weight of self produced every supporter below is on the plunger type pneumatic cylinder, forces the pneumatic cylinder shrink, makes hydraulic oil discharge jar supply hydraulic motor drive generator work outward, for the electric automobile that the battery charges.

Background art:

the current electric automobile has weak cruising ability, needs frequent charging and brings great inconvenience to driving. Meanwhile, the problem of traffic safety that the tires are easy to puncture and explode also exists. It is known that the tire pressure of a vehicle is too high, so that the resistance can be reduced, the vehicle speed can be improved, and the energy consumption can be reduced, but the shock absorption is not facilitated and the tire burst is easy. The tire pressure is too low, and the damping effect is good, but the resistance can be increased, the vehicle speed is reduced, the energy consumption is increased, and the energy conservation and the environmental protection are not facilitated. And the trouble that people carry more people and the people carry need to adjust the tire pressure in time also exists. Therefore, the problems are solved by using the wheel formed by combining the oil damper and the inflation-free solid tire on the bicycle and the wheelchair.

The utility model has the following contents:

in order to overcome the defects of the electric automobile under the prior art, the prior art is fully utilized. The utility model provides an electric automobile that can automatic hydraulic pressure charge when traveling. The vehicle greatly improves the cruising ability, saves energy, protects environment and is simple to manufacture.

The utility model provides a method for its technical problem is: the four-wheel assembly is composed of a hydraulic oil pipe, a plunger type hydraulic cylinder, a hub and a bearing seat. The hydraulic oil output system is formed by respectively installing the hydraulic oil output system on the shaft heads of the front axle and the rear axle and taking the hydraulic oil output system as a chassis at a position below the suspension of the electric automobile. The output hydraulic oil is communicated to the energy accumulator through a hydraulic pipe. An oil outlet of the energy accumulator is communicated with the hydraulic motor to drive the generator, and the hydraulic oil flows back to the oil tank. The hydraulic rotating power generation system is installed in a trunk of the electric automobile. Each wheel is provided with plunger type hydraulic cylinders in spoke shape in equal division, each cylinder is provided with an oil inlet and outlet one-way valve, and oil ports of the cylinders are communicated with corresponding oil inlet and outlet ports respectively. When the electric automobile runs, the hydraulic cylinders on the wheels circularly move along with the wheels. And when the hydraulic cylinder is circulated to be vertical to the ground and is highest, oil absorption is finished. When the circulation is lowest from the ground, the hydraulic oil is completely discharged to the accumulator. The energy accumulator is provided with an adjustable pressure limiting valve, when a person drives the vehicle, the energy accumulator can be adjusted to a first gear and adjusted to a fourth gear step by step along with the increase of the number of people, the adjustable pressure limiting valve ensures that the number of passengers is different and the damping effect is the same, and simultaneously ensures that the more people are carried or the more the roads are overturned, the more the electric quantity generated by the generator is. The maximum energy obtained by the plunger type hydraulic cylinder reduces the running resistance of the vehicle. The set inflation-free tire not only eliminates the potential safety hazard of tire puncture and tire burst, but also reduces the vehicle maintenance cost. In order to avoid damage to the vehicle during impact, a buffer is arranged at the position where the hydraulic cylinder has a liquid cavity which is 10 mm lower than the liquid level. The sealing member provided to avoid the influence of the inertial effect of the centrifugal force generated when the wheel rotates on the sealing performance of the check valve is hollow.

The specific implementation mode is as follows:

referring to fig. 1, the electric vehicle has four wheels, and the structure and the working principle of each wheel are the same. The outer circular arc wall of the hub is provided with an inflation-free solid tire 1, the inner circular arc wall is provided with three equally-divided lifting lugs 4, one end of a hydraulic cylinder 9 in the drawing is fixed by a linkage pin shaft 2, and the other end of the hydraulic cylinder is fixed on a bearing seat 12 in the drawing by a linkage pin shaft, and the shape of the hydraulic cylinder is similar to that of a bicycle spoke. The hydraulic oil supply system is used as a chassis at a position below an automobile suspension and becomes a hydraulic oil supply system. The accumulator 36 is fed to the hydraulic motor 39 to drive the generator 40 to form a hydraulic rotary power generation system, and is mounted in the trunk together with the hydraulic oil tank 41.

As shown in fig. 2 and 3. The hydraulic oil in tank diagram 41 enters from the oil inlet manifold diagram 31 and fills 21 each of the oil reservoirs which are each tightly fixed to the bearing block diagram 12 for the rotation of the wheel. The dynamic and static joints of each reservoir are sealed at one end by an oil seal 18 mounted on the bearing block and at the other end by a stationary plate oil seal 20 mounted on a stationary plate 24. The mounting plate is shown in front axle view at 23 and rear axle view at 32. A pin shaft picture 25 on the fixed disc fixes a brake lever picture 26 and a brake belt picture 19 in a linkage mode. The brake band surrounds the outer arc wall of the oil storage pool, and the inner cavity stores oil. When the electric automobile runs, each hydraulic cylinder on the wheel circularly moves along with the wheel. When oil is fed, the advancing direction of the automobile is taken as an example. When 9 in any hydraulic cylinder figure circulates to the back of a wheel axle and the hydraulic cylinder is larger than an angle parallel to the road surface, 10 in the hydraulic cylinder piston rod figure is gradually stretched due to the self weight of a vehicle, hydraulic oil in 21 in an oil storage pool figure enters from 17 in an oil inlet rubber tube figure under the action of evacuation, 29 in 28 in an oil inlet sealing element figure is forced to compress 27 in a oil inlet spring figure, and an oil inlet passage is formed to the hydraulic cylinder in 3 in a liquid cavity figure like a medical injector for liquid suction. When the hydraulic cylinder moves to the position that the uppermost end of the wheel shaft is vertical to the road surface, the pulling force applied to the piston rod 10 in the drawing is strongest, the piston rod extends to the longest extent, the stroke is 10 millimeters, and the oil is fully sucked. As the wheel continues to rotate, the cylinder tilts forward from vertical to parallel with the road surface, the piston rod 10 gradually decreases to no pumping force, and the oil spring 27 springs the oil seal 29 out to close the oil passage. When oil is drained, the direction of the vehicle is taken as an example. When the hydraulic cylinder 9 moves to the front of the wheel axle and the hydraulic cylinder is smaller than the angle parallel to the road surface, the piston rod of the hydraulic cylinder above the wheel axle is gradually extended and simultaneously the piston rod of the hydraulic cylinder below the wheel axle is gradually compressed due to the weight of the vehicle, and the oil pressure in the hydraulic cylinder 3 in the diagram of the oil cavity forces the oil discharge sealing part 5 in the diagram 7 of the oil discharge one-way valve to compress the oil discharge spring 8 in the diagram to form an oil discharge passage which enters the cavities 15 in the diagram of the outer bearing and 16 in the diagram of the inner bearing from the inside 11 of the oil discharge hose as in the injection of the medical injector. The bearing cover 14 prevents oil from leaking out, and the bearing oil seal 18 prevents hydraulic oil from communicating to the reservoir 21. When the hydraulic cylinder moves to the position where the lowest part of the wheel shaft is vertical to the road surface in the figure 9, the pressure applied to the piston rod 10 in the figure is the largest, the compression is the shortest, the stroke is 10 millimeters, and the oil is completely emptied. Along with the continuous rotation of the wheel, the hydraulic cylinder 9 in the figure is changed from vertical to backward inclined towards the wheel shaft to be parallel to the road surface, the oil in the hydraulic cylinder 3 with a hydraulic cavity figure is gradually reduced to no pressure, the oil discharge spring 8 in the figure pops out the oil discharge sealing element 5 in the figure, and an oil discharge loop is closed. No oil liquid with other through oil passages is needed, and the oil liquid can only be converged with an L-shaped oil passage 22 on a shaft head of a front axle shaft 23 and a shaft head of a rear axle shaft 32 in a cavity of an inner bearing and an outer bearing in a through hole 13 in each bearing block 12 in each bearing block drawing, and then enters an energy accumulator 36 in an oil discharge header drawing 30 through the L-shaped oil passages according to the oil passages which are mutually through. Because the pressure in the nitrogen chamber diagram 33 and the pressure-limiting valve diagram 42 on the accumulator is set to a certain pressure, the hydraulic oil entering the accumulator can only be retained in the oil chamber diagram 34. As the oil pressure increases, the gas in the nitrogen chamber map 33 will be compressed to the set pressure of the adjustable pressure relief valve map 42. The hydraulic oil forces 35 in the pressure limiting valve sealing member diagram to compress 37 in the pressure regulating spring diagram, and enters 39 in the hydraulic motor diagram from the oil outlet of the accumulator to drive 40 in the generator diagram. The operation of the hydraulic motor is returned to tank diagram 41.

When the number of passengers increases or decreases, one person drives and adjusts the gear in the pressure-adjusting handle graph 38. Because the gas in the nitrogen chamber diagram 33 with lower pressure is relatively easy to compress to the set pressure of the pressure limiting valve, the pressure limiting seal diagram 35 is relatively easy to compress the pressure regulating spring diagram 37, and a passage is formed for the hydraulic motor diagram 39 to work. When the number of people is small, the opening pressure of the pressure limiting valve is small, and the shock absorption effect of the hydraulic cylinder is good. When the number of passengers increases, the pressure regulating handle 38 can be adjusted to the fourth gear step by step. Because the pressure is relatively high, the gas in the nitrogen chamber 33 in the figure needs to be improved by three times of compression strength to reach the pressure set by the pressure limiting valve, so 35 in the figure of the pressure limiting sealing member is higher than the three times of pressure of the first gear to compress 37 in the figure of the pressure regulating spring, and an oil supply passage is formed to supply the oil to 39 in the figure of the hydraulic motor. The more people carry, the higher the pressure is opened to the pressure limiting valve, and the electric quantity that the generator sent can be more, but the shock attenuation effect of pneumatic cylinder is unchangeable. In order to prevent the electric automobile from generating strong vibration when running on a bumpy road surface, a buffer device 6 is arranged in a position 10 mm below the liquid level in a liquid chamber 3 of a hydraulic cylinder 9 in a figure, when hydraulic oil is emptied, if the hydraulic oil encounters strong vibration, the tail end of a piston touches the device, so that the hydraulic oil in the hydraulic cylinder is discharged out of a chamber at a faster and higher speed. The more bumpy the road is, the more the oil is discharged, and the more the electricity is emitted.
