Technical Field

[0001] The present invention relates to the technical field of mixer trucks, and in particular to a mixer truck with a built-in hybrid power system. Background Art

[0002] With the continuous progress of society, mixer trucks, as construction transportation vehicles, have been widely used. Mixer trucks for construction need to perform the mixing operation of materials both when driving normally or stopped. For the mixer trucks currently used in the market, the power source for the mixing of the tank body comes from a set of hydraulic systems. The hydraulic pump is connected to the chassis power take-off through a transmission shaft to obtain power, and then the hydraulic pump is controlled by a hydraulic control valve. The hydraulic pump drives the hydraulic oil to drive the hydraulic motor, thereby realizing the rotation of the tank body. Because the tank body needs to rotate continuously, the vehicle cannot turn off the engine during the waiting process. Such a control system has the following defects during long-term use: 1. There is a large energy loss during the mechanical transmission process; the hydraulic oil will also generate a lot of heat during the hydraulic transmission process and consume part of the energy, and the overall hydraulic transmission efficiency is not high; 2. The vehicle cannot turn off the engine, which will also cause fuel consumption and increase the overall energy consumption. Summary of the Invention

Detailed Embodiments

[0015] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the following will further describe the present invention in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0016] In the present application, the drive motor 3, the directly-connected generator 6, the reducer 11, the parking air conditioner 7, and the motor control system MCU and the power battery are directly purchased from the market according to specific models and then matched and installed for use. A reducer 11 is also installed at the connection between the drive motor 3 and the tank 2.

[0017] See Figure 1What is shown is a concrete mixer truck with a hybrid power system, including a concrete mixer truck body 1, a tank body 2 movably arranged on the concrete mixer truck body 1, a front end of the tank body 2 connected to a drive motor 3, one end of the drive motor 3 connected to an electric control system assembly 4 through a wire, one end of the electric control system assembly 4 connected to a direct-connected generator 5 through a wire, and the other end of the electric control system assembly 4 connected to a cab control panel 6 through a wire, and the cab control panel 6 is installed on the cab operating panel.

[0018] Among them, the direct-connected generator 5 is fixedly installed on the frame at the rear end of the cab. One side of the electronic control system assembly 4 is also connected to the parking air conditioner 7 through a wire. One side of the electronic control system assembly 4 is also connected to the rear control panel 8 through a wire, and the rear control panel 8 is installed at the rear of the frame. The electronic control system assembly 4 is also wirelessly connected to the remote control 9. One side of the electronic control system assembly 4 is also connected to the instrument panel 10 through a wire. The electronic control system assembly 4 includes a motor control system MCU and a power battery, and the power battery supplies power to the tank drive system.

[0019] The working principle of the mixer truck with its own hybrid power system is as follows:

[0020] This application is composed of several parts, such as a cab control panel 6, a parking air conditioner 7, a direct-connected generator 6, an electric control system assembly 4, a drive motor 3, a rear control panel 8, a remote control 9, an instrument panel 10 and a reducer 11. The electric control system assembly 4 includes a motor control system MCU and a power battery, and the instrument panel 10 is provided by the chassis. When the vehicle is braking or decelerating, after the electric control system detects a signal, the direct-connected generator 6 is activated to convert mechanical energy into electrical energy and store it in the electric control system (power battery). The direct-connected generator 6 is directly connected to the chassis engine, eliminating the transmission shaft and reducing the energy loss in the mechanical transmission process; in this way, the drive motor 3 can use the electricity in the electric control system (power battery) as an energy source, and the drive motor 3 rotates through the reducer 11 to drive the tank 2 to rotate. The parking air conditioner 2 in the cab can also draw power from the power battery, so that the vehicle can be turned off during the waiting process, saving costs; when the battery power is less than 20%, the chassis engine can be automatically started to charge the power battery, and when the battery power reaches 80%, it can be automatically turned off. The cab is set with an in-cab control panel 1 and a rear control panel 8 set at the rear of the vehicle to control the speed and forward and reverse rotation of the tank body 2, thereby realizing loading and unloading. The control panel 6 in the cab and the rear control panel 8 cannot control the rotation of the tank body 2 at the same time. The rear control panel 8 can be authorized to control the rotation of the tank body 2 in the cab, and the control of the rear control panel can be canceled with one key, and the rotation of the tank body 2 can be controlled by the operation panel 6 in the cab; similarly, the control by the rear control panel 8 can be realized by one key at the rear control panel 8, and the control of the rear control panel can be canceled with one key, and the cab can be controlled; the forward and reverse rotation of the tank body 2 can also be controlled by operating the remote control 9.

[0021] The cab control panel 6 can also be integrated onto the chassis rocker switch, integrated with the chassis, making the appearance cleaner and more beautiful; the operating status speed of the tank body 2, the fault information of the tank body 2, etc. can be integrated and displayed on the instrument panel, saving the display screen.

[0022] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
