[0030] The utility model provides a kind of self-unloading truck 100.

[0032] The technical scheme of the utility model discloses a turnover lever 32 is installed at the tail of the cargo compartment 20, a sensor 31 is arranged at the position of the chassis 10 corresponding to the turnover lever 32, in the process of unloading the self-unloading truck 100 provided by the utility model, the jacking structure pushes up or the cargo compartment 20 overturns upwards, the turnover lever 32 installed at the tail of the cargo compartment 20 overturns from the first position to the trigger position and continues to overturn from the trigger position to the second position. When the turnover lever 32 overturns to trigger the sensor 31, the triggered sensor 31 controls the output power of the jacking structure to reduce through the controller, so that the jacking speed of the jacking structure to the cargo compartment 20 is reduced, the cargo compartment 20 can be jacked at a relatively slow speed when being jacked to a higher height, the jacking of the cargo compartment 20 is divided into two stages with different speeds, the vehicle center of gravity can be prevented from moving forward sharply due to the one-time jacking angle of the cargo compartment 20 being too large, and the vehicle center of gravity can be further prevented from moving forward sharply when the cargo compartment 20 is jacked at a relatively slow speed in the state of being at a higher position, so that the possibility of the self-unloading truck 100 provided by the utility model from overturning in the unloading process is effectively reduced, and the safety hazard is effectively eliminated.
[0033] It should be noted that the interaction between the sensor 31 and the jacking structure and the controller adopts the prior art. The first position is the position of the turnover lever 32 when the cargo compartment 20 is not jacked and is in a flat state, and the second position is the position of the turnover lever 32 when the cargo compartment 20 is jacked to the highest position.
[0034] In an embodiment of the utility model, the jacking structure adopts the hydraulic cylinder in the prior art, and the controller adopts the automobile electronic control unit (ECU) in the prior art.
[0035] In an embodiment of the utility model, the chassis 10 extends along the transverse direction, one side edge of the chassis 10 along the longitudinal direction is the mounting edge 21, and the sensor 31 and the turnover lever 32 are arranged close to the mounting edge 21.

Figure 2
[0041] In an embodiment of the present application, the turnover rod 32 is detachably mounted on the mounting seat 33, so that the turnover rod 32 can be replaced more conveniently.

[0045] In an embodiment of the utility model, the turnover rod 32 can be turned from the first position to the trigger position in the sensing area, the included angle between the turnover rod 32 in the first position and the turnover rod 32 in the trigger position is A; wherein, 45 ° ≤ A ≤ 50 °.
[0046] Further, the included angle between the turnover rod 32 in the trigger position and the turnover rod 32 in the first position is set to be less than or equal to 50 °, which can effectively ensure that the cargo compartment 20 is lifted to a certain height at a lower speed to avoid the dump truck 100 provided by the utility model from tipping over, and the included angle between the turnover rod 32 in the trigger position and the turnover rod 32 in the first position is set to be greater than or equal to 45 °, which can ensure that the dump truck 100 provided by the utility model has a faster unloading speed.

[0048] Specifically, the photoelectric proximity switch has high sensitivity and can quickly capture changes in signals, thereby achieving accurate monitoring and real-time feedback of the turnover position of the cargo compartment 20. This helps to adjust the lifting speed in time during unloading to ensure the safety of operation. Moreover, the photoelectric proximity switch has strong anti-interference ability to environmental light and electromagnetic interference and can work stably in complex industrial environments, having strong stability and adaptability.
[0049] In an embodiment of the utility model, the turnover rod 32 is provided with a magnet, and the inductor 31 is a Hall proximity switch.
[0050] Specifically, the Hall proximity switch can quickly detect the magnetic field changes of the magnet and transmit signals to the controller, thereby achieving accurate monitoring and real-time feedback of the turnover position of the cargo compartment 20. It should be noted that the Hall proximity switch triggers by sensing the change of the magnetic field, and can be triggered when the magnetic field strength sensed by the Hall proximity switch reaches the preset magnetic field threshold. Therefore, by adjusting the size of the preset magnetic field threshold, the trigger position can be quickly adjusted, thereby adjusting the position of the cargo compartment 20 during lifting, and the flexibility is higher.
