[0002] Diesel-powered concrete mixer trucks are gradually being replaced by new energy vehicles such as pure electric and hybrid power, and the control operations of special functions are also shifting from traditional mechanical joysticks to more precise and easier to implement intelligent electronic control operations.

[0003] When loading and unloading concrete, the existing pure electric mixer trucks need to control the forward and reverse rotation and speed of the drum through the operation button electric control handle. Due to the presence of buttons on the electric control handle, the operation logic requirements are high, and therefore the cultural level of the actual operator of the mixer truck is required to be high. In addition, due to the harsh working environment of the mixer truck, the electric control handle often fails, which seriously affects the normal use of the vehicle. Most of the failures are due to button problems.

[0004] Therefore, how to provide a top-mounted drum control system and an electric mixer truck that are easy to operate and more in line with the needs of actual operators is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of the utility model is to provide a special vehicle upper drum control system and an electric mixer truck, which solves the technical problem that the upper drum control system of the electric mixer truck in the prior art has high operation requirements and does not meet the needs of actual operators.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] One of the core aspects of the present invention is to provide a special vehicle-mounted drum control system, which, by adopting a buttonless electric control handle 20, is safer, easier to operate, and more in line with the needs of actual operators.

[0029] Please refer to Figure 1 and Figure 2 The utility model provides a special vehicle-mounted drum control system comprising an operating panel 40, an electric control handle 20, a drive motor, a vehicle control unit, and a motor control unit. The operating panel 40 is mounted in the cab and is used to control the operation of the vehicle drum; the electric control handle 20 controls the operation of the vehicle drum by changing the pushing direction and pushing angle; the drive motor is connected to the drum for driving the drum; the vehicle control unit is connected to the operating panel 40 and the electric control handle 20; and the motor control unit is connected to the vehicle control unit and the drive motor for controlling the direction and speed of the drive motor.

[0030] During operation, by manipulating the operation panel 40 or the electric control handle 20, a control instruction is sent to the vehicle control unit, and the vehicle control unit sends a signal to the motor control unit, which controls the operation of the drive motor to control the forward and reverse rotation and speed of the cylinder. By using the buttonless electric control handle 20, the speed, direction and stop state of the cylinder can be controlled by simply pushing it forward and backward. By pushing the electric control handle 20 forward and backward to send a control instruction to the vehicle control unit, the vehicle control unit sends a signal to the motor control unit, and the motor control unit controls the forward and reverse rotation of the drive motor, thereby controlling the forward and reverse rotation of the cylinder for loading or unloading. By changing the angle when pushing the electric control handle 20 forward and backward, the speed of the drive motor is controlled, thereby controlling the speed of the cylinder. The operation is convenient and simple, with higher safety, and better meets the needs of actual operators.

[0031] Please refer to Figure 3 In the special vehicle-mounted cylinder control system provided by the utility model, the electric control handle 20 is set on the frame 10. The electric control handle 20 includes a left handle and a right handle. The left handle is installed on the side of the driving seat at the rear of the vehicle, and the right handle is installed on the side of the co-pilot seat at the rear of the vehicle. The cylinder is rotated by controlling the left handle and the right handle.

[0032] Please refer to Figure 3 In this embodiment, a mechanical cable 30 is provided between the left handle and the right handle for linking the left handle and the right handle. By providing the mechanical cable 30, the same sensor can receive signal input when the left handle and the right handle are operated, thereby reducing electrical protection points and saving costs while ensuring synchronous operation.

[0033] It should be noted that the handle neutral position is the middle position of the handle control angle variation range, also known as handle position 0. The electric control handle 20 has a rotation angle adjustment range of 4° to the left and right of the neutral position. When the electric control handle 20 is pushed from the neutral position toward the feed direction, the cylinder begins to rotate in the feed direction and accelerates in stages. When the handle is pushed to the maximum angle in this direction, the feed speed reaches its maximum. When the electric control handle 20 is pushed from the neutral position toward the discharge direction (opposite to the feed direction), the cylinder begins to rotate in the discharge direction and accelerates in stages. When the handle is pushed to the maximum angle in this direction, the discharge speed reaches its maximum. When the handle is pushed back to the neutral position from the maximum angle, the cylinder begins to decelerate in stages. When the handle returns to the neutral position, the cylinder stops.

[0034] Please refer to Figure 4 The operation panel 40 includes a feed key, an acceleration key, a constant speed key, a stop key, a discharge key, a deceleration key, a quick key, and a power indicator key. Each of the feed key, the acceleration key, the constant speed key, the stop key, the discharge key, the deceleration key, the quick key, and the power indicator key is provided with an indicator light, wherein the indicator light includes a red light, a yellow light, and a green light to indicate different working states.

[0035] The special vehicle-mounted cylinder control system provided by the utility model has a system in which the control permissions of the operation panel 40 and the electric control handle 20 can be switched with each other, but the control permissions of the operation panel 40 and the electric control handle 20 cannot be switched at will. Compared with the control system in the prior art in which the control permissions can be switched at will, it is safer to use and can effectively avoid safety accidents.
