Description

Technical Field

[0001] The present application relates to the technical field of electric vehicles, and in particular to an electric drive vehicle. Background Art

[0002] At present, the speed of the power take-off of new energy vehicles is mostly controlled by the accelerator pedal. When the power take-off is engaged, the driver needs to step on the accelerator pedal. The different openings of the accelerator pedal make the motor respond to different speeds, thereby controlling the speed of the power take-off to provide power for the operating mechanism. However, due to the high sensitivity of the accelerator pedal, the opening of the pedal cannot be accurately controlled by manual foot control, resulting in the inability to accurately and meticulously control the motor speed, resulting in the inability to better control the speed of the power take-off.

[0003] It should be noted that the statements in this background technology section only provide background technology related to the present application and do not necessarily constitute prior art. Utility Model Content

[0023] refer to Figure 1 and Figure 2 The present application provides an electric drive vehicle, including a power take-off, a motor, an operating table 1 and an adjusting knob 2. The operating table 1 is arranged in a cab of the electric drive vehicle. The adjusting knob 2 is rotatably arranged on the operating table 1, and is used to control the speed of the motor after the power take-off is connected to the motor drive.

[0024] The power take-off is used to connect with the motor drive to extract and output power from the motor to the operating mechanism (for example, an oil pump) for the operating mechanism to operate. After the power take-off is connected with the motor drive, the driver can accurately control the motor speed by rotating the adjustment knob 2, and then accurately adjust the speed of the power take-off. Compared with the prior art, the manual rotation of the knob can control the speed of the power take-off in real time and accurately, thereby improving the control accuracy of the power take-off.

[0025] In some embodiments, the adjusting knob 2 has multiple gears. When the adjusting knob 2 is rotated to different angles, it corresponds to different gears. In different gears, the motor responds to different speeds.

[0026] In some embodiments, each time the adjusting knob 2 increases by one gear, the speed of the motor in response increases by a set value.

[0027] Specifically, the electric drive vehicle also includes a controller, and the adjustment knob 2 sends different voltage signals to the controller when rotating at different angles, and the rotation angle of the adjustment knob 2 is linearly related to the value of the output voltage signal. When the adjustment knob 2 is not rotated, the voltage signal is zero, and the adjustment knob 2 is in zero gear, and the speed of the motor response is zero. When the voltage signal is greater than N-1 and less than or equal to N volts, the adjustment knob 2 is in the Nth gear. The speed of the motor response is R, R = N*k rpm, where N is a positive integer greater than or equal to 1, and k is the increase in the speed of the motor response when the adjustment knob 2 increases by one gear.

[0028] Furthermore, by pre-calibrating the voltage-gear signal curve, when the adjusting knob 2 is rotated at different angles, the voltage signal can be correspondingly converted into a gear signal and output to the controller, and the controller controls the motor to respond to the corresponding speed according to the gear signal. In some embodiments, the adjusting knob 2 has twenty-four gears. For each increase in the gear of the adjusting knob 2, the speed of the motor response increases by 100 rpm.

[0029] Specifically, when the voltage signal is greater than 0 volts and less than or equal to 1 volt, the adjustment knob 2 is in the first gear, and the speed of the motor response is 100 rpm. When the voltage signal is greater than 1 volt and less than or equal to 2 volts, the adjustment knob 2 is in the second gear, and the speed of the motor response is 200 rpm. Similarly, when the voltage signal is greater than 23 volts and less than or equal to 24 volts, the adjustment knob 2 is in the twenty-fourth gear, and the speed of the motor response reaches a maximum value of 2400 rpm. Each time a gear is increased, the motor speed increases by the same value, so that the speed of the motor can be accurately controlled.

[0030] refer to Figure 1In some embodiments, the electric drive vehicle further includes a display panel 3. The display panel 3 is disposed on the operating console 1, and the display panel 3 is used to display the gear position of the adjustment knob 2. The driver can accurately rotate the adjustment knob 2 according to the display panel 3 to make the gear level of the adjustment knob 2 reach a desired value, so as to more accurately control the speed of the motor.

[0031] In some embodiments, the display panel 3 and the adjusting knob 2 are arranged on the side of the operating console 1 facing the driver. Such an arrangement facilitates the driver to observe and obtain the gear level of the adjusting knob 2 more intuitively.

[0032] refer to Figure 1 In some embodiments, a cable interface 5 is further included. The operating console 1 includes a front and a back side that are arranged opposite to each other. The front side faces the driver. The display panel 3 and the adjustment knob 2 are arranged on the front side. The cable interface 5 is arranged on the back side. The cable interface 5 is used to connect a low-voltage wire harness to provide an electrical signal or electrical energy to the adjustment knob 2 and the display panel 3.

[0033] refer to Figure 1 and Figure 2 In some embodiments, the electric drive vehicle further comprises a mounting plate 4 disposed at the edge of the operating platform 1. The mounting plate 4 is used to connect with the interior panel in the cab. Specifically, the operating platform has a rectangular profile, and the mounting plate 4 is symmetrically disposed at the edge of the operating platform 1, so that the operating platform 1 is conveniently mounted on the interior panel.

[0034] refer to Figure 1 and Figure 2 In some embodiments, the edges of the mounting plate 4 are rounded to reduce the risk of the edges of the mounting plate 4 scratching people.

[0035] refer to Figure 2 In some embodiments, the electric drive vehicle further comprises a reinforcing rib 6. The reinforcing rib 6 is connected between the body 1 and the mounting plate 4. The reinforcing rib 6 is arranged on the back of the operating table 1. The reinforcing rib 6 can improve the stability of the connection between the operating table 1 and the mounting plate 4.

[0036] In some embodiments, the adjusting knob 2 is configured to be pressable. When the adjusting knob 2 is pressed, the power take-off is connected to the motor driving device.

[0037] Specifically, when the adjustment knob 2 is pressed, the power take-off is connected to the motor drive, and the power take-off can now take power from the motor. Under this condition, the driver rotates the adjustment knob 2 to achieve precise control of the motor speed, and thereby precisely control the torque output by the power take-off.

[0038] In some embodiments, the electric drive vehicle further includes a gearbox and a power take-off mounting position corresponding to the gearbox. The gearbox is connected to the motor. The power take-off mounting position is used to mount the power take-off. When the power take-off is mounted at the power take-off mounting position, the power take-off can be connected or disconnected from the gearbox. The power take-off includes a first power take-off and a second power take-off. The first power take-off and the second power take-off can output different torques. One of the first power take-off and the second power take-off can be selectively mounted at the power take-off mounting position.

[0039] The first power take-off and the second power take-off can output different torques, so different power take-offs can be installed to adapt to different working conditions according to different working requirements. For example, the maximum torque that the first power take-off can continuously output (for example, 500Nm) can adapt to most working scenarios. In some special working scenarios, the maximum torque that the power take-off needs to continuously output is greater than 500Nm. At this time, the first power take-off can be removed and the second power take-off can be installed. The maximum torque that the second power take-off can continuously output is greater than 500Nm (for example, 700Nm), which can meet the working requirements.

[0040] Specifically, the gearbox includes an input shaft, an intermediate shaft and an output shaft that are sequentially connected in a transmission manner. The input shaft is connected to the motor for transmitting power from the motor to the intermediate shaft. The output shaft is connected to the transmission shaft of the electric drive vehicle to output power to the wheels. The power take-off is connected to the motor in a driving manner to take power, which means that the power take-off is connected to the intermediate shaft of the gearbox through gear meshing (since the motor is always meshed with the input shaft of the gearbox, and the input shaft is always connected in a transmission manner to the intermediate shaft, the power take-off is controlled to be meshed with the intermediate shaft). For example, when the first power take-off is installed in the power take-off installation position, the first power take-off is controlled to mesh with the intermediate shaft gear, so that the power of the motor is output to the operating mechanism through the input shaft, the intermediate shaft and the first power take-off. Similarly, when the second power take-off is installed in the power take-off installation position, the second power take-off is controlled to mesh with the intermediate shaft gear, so that the power of the motor is output to the operating mechanism through the input shaft, the intermediate shaft and the second power take-off.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present application can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present application, which should be included in the scope of the technical solution for protection in the present application.
