[0027] Embodiment:

[0028] A device for recovering and utilizing the kinetic potential energy of a vehicle during high-speed driving, as Figure 2 shown, includes a mounting plate 1. One end of the mounting plate 1 is connected to the vehicle through a connecting rod 2, and the other end thereof is provided with an energy recovery wheel 3. The middle part of the mounting plate 1 is connected to the vehicle through a lifting mechanism 4. A recovery and utilization mechanism 5 is also provided on the mounting plate 1. The recovery and utilization mechanism 5 is drivingly connected to the energy recovery wheel 3 through a belt 6.

[0029] Further, the upper end of the connecting rod 2 is fixedly connected to the vehicle frame / girder, and the lower end of the connecting rod 2 is rotatably connected to the mounting plate 1.

[0030] Further, the upper end of the lifting mechanism 4 is rotatably connected to the vehicle frame / girder, and its lower end is rotatably connected to the mounting plate 1.

[0031] Further, the rotating shaft of the energy recovery wheel 3 and the input shaft of the recycling mechanism 5 are drivingly connected through a belt 6.

[0032] Further, the recycling mechanism 5 is a hydraulic pump or a generator set.

[0033] Further, the lifting mechanism 4 is a hydraulic push rod, a pneumatic push rod or an electric push rod.

[0034] In a possible implementation, the total weight of the body, semi-trailer and goods of a large semi-trailer logistics refrigerated tractor is 48 tons (the national highway transportation load limit standard). When driving on the highway, the average speed is about 81 kilometers per hour. According to the force calculation method of physical kinematics (the law of conservation of force), 48×1000 = 48000 kilograms, and 48000÷75 = 640 horsepower of moving force. According to the physical power measurement method, 1 horsepower is defined as the moving distance of 1 meter per second for 75 kilograms. The moving distance generated per second at a speed of 81 kilometers per hour is 22.5 meters. The inertial (impact) potential energy generated is converted into horsepower, which is approximately 640×22.5 = 14400 horsepower. This is only calculated based on the actual weight of the object. This is only 22 times, but the inertial (impact) potential energy of an object with a weight of 1 kg at a moving distance of 10 meters per second, the impact potential energy is about 50 kg, which is 50 times the weight of the object itself.

[0035] In a possible implementation, a refrigerated truck requires a diesel generator set to ensure the temperature of the freezer in the refrigerated truck. However, the exhaust gas emitted when the diesel engine of the refrigerated truck operates will pollute the environment. In this application, the inertial (impact) potential energy of the vehicle drives the generator of the refrigerated truck to work, thus reducing the exhaust gas emissions of the diesel engine of the refrigerated truck. This application provides a clean energy power generation device for use in refrigerated trucks. The power of the diesel engine of the refrigerated truck is approximately 60 - 80 horsepower. The working force that the generator of the refrigerated truck needs to extract is only five-thousandths of the moving force of the vehicle during driving. Therefore, the refrigerated truck requires electrical support to ensure the freshness of the transported items.

[0036] In a possible implementation, this application captures and extracts the inertial (impact) potential energy of an automobile (locomotive) during driving and converts it into electrical energy and high-pressure liquid flow energy. This energy capture and extraction device is set according to the energy requirements of the automobile (locomotive). The adhesion force between the capture and extraction equipment and the road surface (rail) can be set between 200 - 10000 N (the adhesion force of the support equipment is 20 - 1000 kilograms. The adhesion force for automobile energy extraction is generated by contact with the road surface, and the adhesion force for train energy extraction is generated by contact with the rail. 1 kg of adhesion force is equal to 9.8 N).

[0037] Furthermore, when the automobile (train) is moving forward at high speed, the energy recovery wheel 3 is lowered, and the adhesion between the energy recovery wheel 3 and the road surface (rail) is utilized to generate a rotational force to drive the recycling mechanism 5 to work. At this time, the recycling equipment converts the recovered energy into high-pressure liquid flow (throughput) or electric energy.

[0038] In a possible implementation, one horsepower is the force that can move a 75-kilogram object one meter per second on average within one hour. The electric energy generated by one horsepower in one hour is 0.735 kw.

[0039] Furthermore, the single generator of the Three Gorges power generation set has a flow rate of 1000 cubic meters (tons) per second, and the inlet diameter is 9800 mm. With a flow rate of 1000 cubic meters (tons) per second, theoretically, in combination with the law of conservation of physical energy, if it takes more than 13000 horsepower to move 1000 cubic meters (tons) of water in one second, the matching motor power should be greater than 9800 kw.

[0040] Furthermore, the impact force generated by a one-kilogram object moving at a speed of 10 m per second is 50 times the weight of the object itself. The water flow velocity of the Three Gorges power generation set per second is approximately 13.3 m. The installed capacity of the actual Three Gorges power generation set is 700,000 kilowatts per unit. Therefore, the capacity of the Three Gorges generator is the power generated based on the water flow velocity, which is more than 70 times the power of moving the object (water) itself. The speed of an ordinary passenger train during high-speed movement is more than 30 m per second, and the overall body weight is more than 800 tons.

[0041] Furthermore, wind power generation extracts the natural wind energy and converts it into mechanical rotational force to drive the generator to work. Hydroelectric power generation extracts the water pressure when water flows (the water stored in the reservoir dam) and converts it into mechanical rotational force to drive the generator to work. This application converts the inertial (impact) potential energy generated when the automobile (train) is moving at high speed into mechanical rotational force to drive this equipment to work.

[0042] In a possible implementation, the energy recovery wheel 3 and the recycling mechanism 5 adopt gear transmission or chain sprocket transmission.

[0043] In a possible implementation, as Figure 1 shown, the recycling mechanism 5 includes a hydraulic pump and a power generation set. The rotating shaft of the energy recovery wheel 3 is connected to the input shaft of the hydraulic pump through a belt 6 in a driving manner, and the input shaft of the hydraulic pump and the input shaft of the power generation set are connected through a belt 6 in a driving manner.

[0044] In a possible implementation, the inertial impact energy generated during the normal (high-speed) driving motion of a heavy-duty towing semi-trailer truck is composed of the inertial potential energy generated based on the total weight of the goods and the vehicle body of 48,500 kg (the total weight of a semi-trailer truck limited by the national highway load standard cannot exceed 49 tons) and the power output by the vehicle power engine (the maximum power of the vehicle used during testing is 650 horsepower and the maximum output torque is 2,800 N / m). The power output by the vehicle power engine mainly ensures the attenuation of the inertial impact potential energy during the normal (high-speed) driving motion of the vehicle.

[0045] Furthermore, when the heavy-duty truck is driving on the highway, its speed is about 90 kilometers per hour, which is approximately 25 meters per second. According to the law of conservation of energy (one horsepower is defined as transporting a 75-kg object a distance of 1 meter per second on average in one hour), 48,500÷75×25 = 16,160 horsepower. When the vehicle is driving at high speed, on flat roads and within a 2% slope increase of the road surface, the power output by the vehicle power engine is approximately between 20% and 50% of the vehicle's maximum power (as shown by the energy loss display on the vehicle's interior meter, the current energy loss of the vehicle is controlled by the vehicle's on-board computer control system for the energy consumption during driving). The vehicle's interior meter shows that the energy consumption of the vehicle (petroleum for fuel vehicles and electric energy for new energy vehicles) is the largest during starting, uphill driving, and acceleration, while the energy consumption decreases during high (constant) speed driving.

[0046] Furthermore, when the towing semi-trailer truck is driving at high speed (90 kilometers per hour), the torque (force) transmitted from the vehicle power engine to the vehicle drive system fluctuates around 1,000 N / m. The moving power generated by the 48,500 kg moving at a distance of 25 meters per second is approximately 16,160 horsepower. At this time, the moving inertial potential energy generated by the inertial (impact) potential energy is maintained at approximately 160 million joules of moving energy.

[0047] In a possible implementation, a limit test is conducted on the inertial impact energy extraction device. This test is based on the power output by the semi-trailer truck power engine, and the recovered energy does not exceed the maximum power output by this semi-trailer truck power engine. Therefore, this limit test is set with the maximum power output by the vehicle power engine of this vehicle model as the limit critical point. This limit test method is to control the recovery of inertial potential energy by turning on and off the vehicle during high-speed driving. The attachment support force of this device (extracting inertial potential energy) in contact with the road surface is 3,000 N (the maximum output power of the power engine is 2,800 N / m, and about 10% of the energy is lost during energy extraction and transmission);

[0048] Furthermore, the test is carried out continuously when the vehicle speed of the car is between 50 and 90 km / h. When this device does not extract inertial potential energy and coasts synchronously with the car without affecting the driving speed of the car and increasing the energy loss of the car, the inertial impact energy recovery device is turned on for extreme testing. The adhesion support force between this device and the road surface is designed to be 3000 N. In this test, the rotation of the adhesion support wheel is directly locked. When the energy locked by the energy recovery wheel is greater than the adhesion force of 3000 N, the inertial potential energy extraction support energy recovery wheel 3 directly stops rotating. At the same time, the energy recovery wheel 3 contacts the road surface and the friction tire directly heats up and melts. According to the law of conservation of dynamic force, it is calculated that the force of the energy recovery wheel at this time is greater than 3000 N. However, when this energy recovery wheel is doing extreme motion testing, it has no impact on the driving speed of the car, and there is no sign of increased energy loss shown on the car energy loss meter either.

[0049] It can be seen from the test results that when the total weight of the semi-trailer tractor is 48.5 tons and it is moving normally (at high speed), the diameter of the adhesion wheel of the device is 0.35 m, and the rotational speed per kilometer is 909.8 revolutions. When the extracted inertial impact energy is not greater than the maximum power output of the vehicle power engine (3000 N / m), it will not affect the normal (high-speed) driving motion of the car, and at the same time, there is no obvious increase in the energy loss of the car. This device is fixedly connected to the vehicle body and is towed by the vehicle body, similar to the tow hook connection of a train carriage and also similar to the landing gear of an airplane, and will not affect the driving safety of the car.

[0050] In summary, in this application, the inertial impact potential energy generated when the car (train) is moving normally (at high speed) is used to drive the device of this application to move in the same direction. At this time, the device of this application naturally generates a moving sliding rotational force that is converted into mechanical motion force. In wind power generation, the rotational force of the wind turbine blades is converted into mechanical motion force. In hydropower generation, the water flow is used to impact the water wheel to rotate, and the rotational force of the water wheel is converted into mechanical motion force. The present invention is a method of extracting the rotational force generated by the support force of the energy recovery wheel 3 of this device during the sliding motion driven by the inertial potential energy of the car (train) and converting it into mechanical motion force.

[0051] By adopting the above technical solutions:

[0052] In this application, the recovered energy drives the generator to work and is converted into electric energy to increase the cruising range of new energy vehicles. The application in refrigerated (logistics) vehicles reduces the exhaust emissions of the fuel-powered engines of the refrigerated (logistics) vehicle generator sets. The recovered energy drives the hydraulic pump to work, and the high-pressure liquid is released into the vehicle power transmission system, reducing the power output of the vehicle power engine. For fuel vehicles, it reduces the energy loss of the fuel vehicle and reduces the exhaust emissions of the fuel vehicle.

[0053] Working principle, refer to Figure 1-2, during use, the energy recovery wheel 3 is also a support point for supporting this device. When the vehicle generates inertial (impact) potential energy during movement, the lifting mechanism 4 lowers the mounting plate 1. At this time, the adhesion force between the energy recovery wheel 3 and the road surface or rail is converted into the working force of this device, driving the hydraulic pump or motor to work. The working force of the lifting mechanism 4 can be divided into pneumatic lifting, hydraulic lifting, and motor lifting. The recycling mechanism 5 is a generator set when a generator is needed to supplement the vehicle's electrical energy, and it can be applied to refrigerated trucks and new energy vehicles.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
