Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] This utility model provides an automated side-unloading cargo box and vehicle, wherein, as Figures 1-5 As shown, the automated side-unloading container includes: The cargo box body 10 is provided with a side unloading door 11 on its side; A side-discharge lifting device is connected between the vehicle frame assembly 20 and the cargo box body 10. It is used to automatically lift the cargo box body 10 towards the side with the side-discharge door 11 during unloading. The side-discharge lifting device can adopt the existing device structure for lifting one side of the cargo box body 10, which will not be described in detail here. Locking device 13 is connected to the cargo box body 10 and is used for automatic locking and releasing of the free end of the side unloading door 11. Locking device 13 includes, but is not limited to, one of the following: electric locking device, pneumatic locking device, hydraulic locking device, bolt lock, rotary latch lock (rotary lock), electromagnetic lock, linkage lock, etc. The guide plate 14 is located adjacent to the free end of the side unloading door 11, and one end of the guide plate 14 is rotatably connected to the cargo box body 10. The rotatable connection includes, but is not limited to, hinge and pivot connection. When the guide plate 14 is in the retracted state, it can drive the free end of the side unloading door 11 to move toward the cargo box body 10, thereby avoiding the problem of locking failure when closing the side unloading door 11 after unloading because the free end of the side unloading door 11 cannot be completely closed. The flipping mechanism 15 is connected to the guide plate 14 and is used to control the guide plate 14 to automatically flip and unfold during unloading so as to guide the goods to an area laterally away from the wheels, and to automatically flip and retract after unloading. The side-discharge lifting device, locking device 13, and tilting mechanism 15 are all connected to the control device via signal connection. The signal connection includes, but is not limited to, wired connection and wireless communication connection. The control device controls the side-discharge lifting device, locking device 13, and tilting mechanism 15 to perform corresponding actions. The control device includes, but is not limited to, the vehicle's own control system and / or an external remote control, a manual operation controller, and / or an automatic operation controller according to a set program.

[0019] During operation, after the vehicle travels to the designated unloading area, the control device controls the locking device 13 to release the free end of the side unloading door 11. Immediately afterwards, the control device controls the tilting mechanism 15 to tilt the guide plate 14 at the bottom of the side unloading door 11 from the unloading area. Figure 1 The storage state shown is flipped to the position shown. Figure 2 In the unfolded state shown, the bottom of the side unloading door 11 will first open a gap, through which the goods will be unloaded. Then, the side unloading lifting device will lift the cargo box body 10 and, under the action of the rotating shaft, begin to rotate along the rotating shaft to a set angle. After the cargo is unloaded, the above operation is reversed. Finally, the guide plate 14 is controlled by the flipping mechanism 15 to press the free end of the side unloading door 11 against the cargo box body 10, and the free end of the side unloading door 11 is locked by the locking device 13.

[0020] The automated side-unloading cargo box provided in this embodiment of the utility model, through the combination of a control device with the cargo box body, a side-unloading door, a side-unloading lifting device, a locking device, a guide plate, and a flipping mechanism, achieves automated and rapid side unloading, improves unloading efficiency, reduces labor consumption, and solves the problems of existing side unloading methods, such as the need for manual insertion and removal of bolts and adjustment of guide brackets, resulting in laborious unloading and extended unloading time. Furthermore, on the one hand, the guide plate guides the goods to an area laterally away from the wheels, which can avoid the phenomenon of excessive goods accumulating on the wheels or vehicle body. On the other hand, when the guide plate is flipped and retracted, it can push the free end of the side-unloading door towards the cargo box body, which can prevent the problem of the free end of the side-unloading door not being able to close completely, resulting in locking failure.

[0021] In specific implementation, such as Figure 1 , Figure 2 As shown, a lifting device 16 is provided between the upper side wall of the side unloading door 11 and the side wall of the cargo box body 10. The lifting device 16 includes, but is not limited to, a hydraulic cylinder, a drive motor rod, etc. The lifting device 16 is connected to the control device. The lifting device 16 is used to pull up the side unloading door 11 when unloading from the side to increase the unloading opening. It can assist the side unloading door to open and close smoothly. On the one hand, it can prevent the goods from getting stuck in the door gap, improve the unloading smoothness, and solve the problem of incomplete unloading. On the other hand, it retracts slowly during the unloading process, thereby achieving the effect of slowly opening the side unloading door 11 and preventing the safety hazards caused by unloading too much goods at once.

[0022] In specific implementation, such as Figure 1 As shown, the side wall of the cargo box body 10 is equipped with a lighting lamp 17. By setting the lighting lamp 17, unloading can be carried out in poor lighting conditions or at night, which enhances the safety and accuracy of unloading operations and reduces the risk of operational errors.

[0023] In specific implementation, such as Figure 1 , Figure 2 As shown, the side-unloading lifting device includes a lifting drive unit 121 and a rotating shaft (such as...). Figure 2 As shown in the figure (not labeled); the lifting drive device 121 is connected to the control device via a signal; one end of the cargo box body 10 with a side unloading door 11 is connected to the frame assembly 20 (as shown in the figure) via a pivot. Figure 2 The right side is rotatably connected, and the other end is connected to the frame assembly 20 (such as the right side) via the lifting drive device 121. Figure 2 (Left side) connection; the lifting drive device 121 includes, but is not limited to, hydraulic cylinders, lifting motors, etc.

[0024] In specific implementation, such as Figure 1 , Figure 3 and Figure 4 As shown, the locking device 13 includes a locking drive device 131, a pin 132, and a pin positioning structure 111; the locking drive device 131 includes, but is not limited to, a hydraulic cylinder, a linear reciprocating motor, etc. The free end of the side unloading door 11 is provided with a pin positioning structure 111 on the side wall of the cargo box body (10); the pin positioning structure 111 includes, but is not limited to, positioning holes, positioning grooves, etc. The locking drive device 131 is mounted on the frame assembly 20 and is signal-connected to the control device; The latch 132 is connected to the output end of the locking drive device 131. Under the control of the control device, the locking drive device 131 can drive the latch 132 to insert into the latch positioning structure 111 to lock the side unloading door 11. The locking device 13 provided in this embodiment has a simple structure and realizes the automatic control of the latch and the positioning structure by the locking drive device, which can realize the quick locking of the side unloading door and greatly save operation time and manpower.

[0025] Better, such as Figure 4 As shown, when multiple pins 132 and multiple pin positioning structures 111 are provided, the multiple pins 132 are set on the side wall of the connecting rod 134. One end of the connecting rod 134 is connected to the driving end of the locking drive device 131, and the linkage and fixation of multiple pins 132 are realized through the connecting rod 134.

[0026] When the connecting rod 134 is too long, it can be connected to the bottom of the vehicle frame or cargo box body 10 through a bearing to improve the stability of the connecting rod 134.

[0027] In specific implementation, such as Figure 1 As shown, the guide plate 14 extends along the length of the opening of the side unloading door 11; the height of the free end of the guide plate 14 when retracted is higher than that of the free end of the side unloading door 11. The higher height of the free end of the guide plate 14 when retracted allows it to naturally push the side unloading door back to its original position during the retraction process, ensuring that the door is tightly closed after unloading and preventing cargo leakage or abnormal locking.

[0028] In specific implementation, such as Figure 4 As shown, a locking detection sensor 133 is provided adjacent to the pin positioning structure 111. The locking detection sensor 133 is connected to the control device via a signal connection. The locking detection sensor 133 is used to detect whether the locking device 13 is locked in place. The locking detection sensor 133 includes, but is not limited to, photoelectric detection sensors and visual detection sensors. By monitoring the locking status of the pin in real time through the locking detection sensor 133 and feeding back a signal to the control device, safety hazards caused by accidental opening of the box door or incomplete closing of the side unloading door 11 during unloading due to misoperation are avoided, thereby improving vehicle safety.

[0029] In specific implementation, the locking detection sensor 133 is a limit switch; the roller end of the limit switch contacts the side wall of the output shaft of the locking drive device 131. Limit switches are existing products, and their working principle and structure are existing technology, which will not be described in detail here. This embodiment uses a limit switch for detection, which is simple in structure, highly responsive, highly reliable, reduces the failure rate, and has low maintenance costs.

[0030] Preferably, the detection end of the limit switch is located on one side of the drive end of the locking drive device 131. When the drive end of the locking drive device 131 moves to the set position (the position where the detection end of the limit switch is located), the detection end of the limit switch can be pushed to move, thereby completing the detection. When the control device controls the locking device (13) to lock the side unloading door 11, but the limit switch does not detect that the drive end of the locking drive device 131 has reached the set position, a door locking abnormality is issued and an alarm is issued to notify the on-site staff or driver, thereby improving safety performance.

[0031] In specific implementation, such as Figure 1 , Figure 3 As shown, the tilting mechanism 15 includes a guide shaft 151, a connecting arm 152, and a guide drive device 153, wherein the guide drive device 153 includes, but is not limited to, a hydraulic cylinder, a reciprocating drive motor, etc. The guide shaft 151 extends along the length of the doorway where the side unloading door 11 is located; The guide plate 14 is fixedly installed on the guide shaft 151; Two flow-guiding drive devices 153 are respectively disposed at both ends of the flow-guiding shaft 151, and the two flow-guiding drive devices 153 are fixed to the side wall of the vehicle frame or cargo box body 10, such as Figure 1 As shown, the output end of the flow guiding drive device 153 is connected to the flow guiding shaft 151 via a connecting arm 152. The connecting arm 152 is movably connected to at least one of the output end of the flow guiding drive device 153 and the flow guiding shaft 151. The flipping of the guide plate 14 connected to the flow guiding shaft 151 is achieved through the telescopic linkage between the connecting arm 152 and the flow guiding shaft 151 at the output end of the flow guiding drive device 153. The flipping mechanism 15 provided in this embodiment has a simple structure, is easy to implement, and is convenient to operate.

[0032] Preferably, the middle part of the guide shaft 151 can be connected to the frame or cargo box body 10 through a bearing or support structure (not shown in the figure) to improve the structural strength and stability of the guide shaft 151.

[0033] This utility model also provides a vehicle that uses any of the above-described automated side-unloading cargo boxes.

[0034] In specific implementation, such as Figure 5 As shown, the vehicle also includes a side-dumping cargo box, a chassis 30, a slewing device 31, and an axle 32, wherein: The chassis 30 has a side-loading cargo box on its upper side and is connected to at least one axle 32 on its lower side via at least one slewing device 31. Driving the slewing device 31 can cause the connected axle 32 to steer. Specifically, the slewing device 31 may include, but is not limited to, existing slewing bearings. At least one axle 32 is provided at the bottom of the output end of the slewing device 31. The input end of the slewing device 31 is provided with a drive device, which may include, but is not limited to, a motor, a cylinder, or a hydraulic cylinder. The drive device drives the input end of the slewing device 31 to rotate, thereby causing the output end of the slewing device 31 to rotate, which in turn causes at least one axle 32 connected to the output end to rotate, thus achieving steering. One or more of the axles 32 are drive axle structures to drive the vehicle. The side-discharge container is used for side lifting and unloading. The side-discharge container can adopt the existing side-discharge container structure, which will not be described in detail here.

[0035] The vehicle provided in this embodiment of the utility model replaces the traditional steering axle structure with a slewing device, which allows for more precise steering angle control when turning, enabling the side-dumping vehicle to drive safely on narrow roads with small turning radii.

[0036] Furthermore, the chassis 30 is provided with two rotating devices 31.

[0037] In specific implementation, such as Figure 2 As shown, two slewing devices 31 are distributed along the length of the underside of the chassis 30. Compared with setting one slewing device 31, setting two slewing devices 31 can make the steering control more precise, enabling the vehicle to meet the requirements of high steering precision control.

[0038] Furthermore, the rotary device 31 is provided with two axles 32.

[0039] In specific implementation, such as Figure 5 As shown, the output ends of the two slewing devices 31 simultaneously drive the two axles 32 to steer. By increasing the number of axles 32, the vehicle's cargo capacity can be improved. At the same time, by setting the two axles 32 on the two slewing devices 31 respectively, the steering accuracy control of the vehicle under heavy load can be improved, enabling the heavy load side-dumping vehicle to drive safely on narrow roads with small turning radii. Thus, the side-dumping vehicle can drive safely on narrow roads with small turning radii under heavy load.

[0040] In specific implementation, such as Figure 5 As shown, the chassis 30 is equipped with an anti-collision device 33, which is used to improve driving safety and prevent or reduce the damage and loss caused by collision accidents.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
