Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

An energy conversion system for a truck realizes the braking of the truck by using the magnetic resistance of a motor, and realizes the energy recovery in the braking of the truck.

The energy conversion system includes an electric machine module 10, and the electric machine module 10 includes an electric machine and its associated circuitry. When the motor is input with electric energy, the motor outputs rotating speed through the output end to convert the electric energy into mechanical energy. When the rotating speed output end of the motor is reversely provided with the rotating speed, the mechanical energy is converted into the electric energy. Therefore, in the braking process of the truck, the mechanical energy in the braking process can be input into the motor to realize power generation.

As shown in fig. 1, the connection of the motor module 10 to the wheel 100 of the truck needs to be realized through the connector 50, that is, the rotation speed of the wheel 100 of the truck is transmitted to the motor, and the braking of the wheel 100 is realized through the magnetic resistance of the motor.

The rotation of the wheel 100 is also realized by the transmission shaft based on the rotation speed output by the motor through the rotating shaft. The connectors 50 may be gears provided to the motor rotation shaft and the transmission shaft of the truck wheel 100, respectively, and engaged with each other.

In particular implementations, the motor-based shaft needs to be coupled to the drive shaft of the truck wheel 100, and thus the connector 50 may be modified or coupled to other mechanical structures as needed.

In order to implement the conventional brake shoe brake system to continue braking the truck, the mechanical brake unit 40 is still connected to the wheel 100 to cooperate with the motor module 10 to complete braking.

The circuitry associated with the motor module 10 may be powered and, as shown in fig. 2, coupled to the battery 60 to couple the electrical energy generated by the generation of electricity to the battery 60 to enable storage of the electrical energy.

The electric controller 20 is an electric control system, and includes a background for logic operation and a signal execution circuit module. As shown in fig. 4, the electric controller 20 is connected to the brake pedal 30, the motor module 10 and the mechanical brake unit 40.

The electric controller 20 is connected to the brake pedal 30 to receive an actuation signal from the brake pedal 30 when depressed. An electric controller 20 is connected to the motor module 10 to control the operation of the motor through an execution circuit of the motor operation. The electric controller 20 is connected to the mechanical brake unit 40 to transmit the mechanical braking command of the truck to the mechanical brake unit 40, and through a specific execution module, the mechanical brake is enabled to implement a braking action. The mechanical brake unit 40 is generally related to hydraulic braking, i.e., an electrical control signal is sent to the hydraulic control to indicate that the mechanical brake is braking or stopping the braking, and the structure is shown in fig. 3.

Because the electric controller 20 includes a background with a logic operation function, when the brake pedal 30 is stepped on, a braking signal is sent out, and a signal for generating braking through the motor module 10 is generated in advance through the background operation of the electric controller 20, so that the motor module 10 is connected to a brake system of a truck to realize braking, and the energy in the braking process is converted into electric energy to be stored. When the stored electric energy reaches the set maximum value, the electric energy acts on the background of the electric controller 20 through feedback logic, and then a mechanical braking instruction is sent to the mechanical braking unit 40, so that mechanical braking is performed.

A Cooperative Regenerative Braking System (CRBS) in the braking energy recovery technology can implement the above-described motor braking first and then mechanical braking.

The braking method has the advantages that the energy is recovered into electric energy for standby in the braking process, so that more energy is saved, and especially for a long-distance truck which can generate a large amount of braking behaviors in the driving process, the recovered energy is considerable. In addition, most of the braking energy is recovered through the motor in the braking process, so that great braking pressure cannot be caused to a mechanical braking system, the abrasion to a brake shoe is small, and the safety and the durability of the mechanical brake are further improved. And because the mechanical brake needs to be cooled by water under the existing condition due to the high-strength brake, the mechanical brake saves or avoids water consumption in cooling of the mechanical brake on the basis of reducing the mechanical brake, and saves water resources.

When the motor module 10 is used specifically, in addition to energy conversion for braking the truck to generate electricity, when the power of the truck is insufficient, the motor can be driven by electric energy to assist the rotation of the wheel 100. Therefore, in some embodiments, a switch 70 is also provided, the switch 70 being connected to the motor module 10 and the electric controller 20.

When the output rotating speed of the motor in the motor module 10 is needed, the electric controller 20 sends a switching signal to switch the switch 70, so as to adapt to the output rotating speed of the motor, and further output the rotating speed to the wheels 100 of the truck when the motor is powered on, thereby realizing the power assistance.

In order to design the stepping brake of the brake pedal 30, in some embodiments, as shown in fig. 6, a sensor 80 is disposed at the brake pedal 30 to sense the stepping action of the brake pedal and the stepping depth, and the sensor 80 transmits the sensed signal to the electric controller 20 to make a logic judgment by the electric controller 20.

In specific implementation, the sensor 80 may be a contact switch for triggering a signal by contact, a hall sensor for determining the stepping angle of the brake pedal 30 by magnetic induction, or a photoelectric switch for determining stepping by an optical signal.

In some embodiments, the motor module 10 is provided to a rear axle location of the truck, adjacent to a rear axle differential, for accessing the rear wheel of the truck through the connector 50 via the differential location, in particular, the drive shaft of the truck wheel 100 through the connector 50.

In some embodiments, as shown in fig. 7, the energy conversion system further comprises a solar panel 90 for receiving solar energy, and the solar panel 90 is connected to the storage battery 60 to store the electric energy converted from the solar energy.

The above examples only represent preferred embodiments of the present invention, which are described in more detail and detail, but are not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
