Description

Technical Field

[0001] This utility model relates to the technical field of side-dumping cargo box structure, and in particular to a novel side-dumping cargo box structure and vehicle. Background Technology

[0002] Side-dump trucks are widely used in bulk material transportation, enabling rapid unloading of goods by tilting and lifting the cargo box laterally. Most existing side-dump trucks employ a bottom-mounted lifting device design, where hydraulic or pneumatic cylinders are positioned between the cargo box bottom and the vehicle frame. While this structure allows for cargo box lifting, it significantly occupies chassis space or reduces the effective cargo volume, lowering transportation efficiency. Furthermore, limited by the installation location and lever arm length of the lifting device, the maximum lifting angle of most existing trucks is only around 45°. This insufficient angle for cargo to slide during unloading can lead to incomplete unloading or require multiple adjustments to the cargo box's position, impacting operational efficiency.

[0003] On the other hand, traditional side-dump cargo boxes typically feature simple opening and closing doors that only function to close or open during unloading. Due to the limited lifting angle, cargo tends to accumulate near the tires, causing a "wheel burial" phenomenon that requires additional clearing or vehicle movement, increasing operational complexity. Furthermore, the cargo box exhibits poor stability after lifting, posing a risk of tipping over. While some designs attempt to add auxiliary outriggers to the bottom of the cargo box, these outriggers are usually independent of the side-dump door structure, cumbersome to operate, and unable to coordinate with the unloading process. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a novel side-discharge cargo box structure and vehicle. The novel side-discharge cargo box structure includes: The container is equipped with a cargo residue detector; the side wall of the container is provided with a side unloading port; the side unloading port is provided with a side unloading door; the lower end of the side unloading door is hinged to the container, and the upper end is provided with several pin structures between the door and the container, the pin structures being used to fix the upper end of the side unloading door when closed; the ratio of the height of the side unloading door to the height of the container is greater than or equal to 0.6. The upper side wall of the side unloading door is also provided with telescopic support legs, which are used to extend to the ground during unloading to support the side unloading door. The upper ends of the two outer side walls of the box body in the direction of travel are provided with lifting connection parts, which are connected to the lifting end of the lifting device; the lifting device is located at the lower end of the side of the box body in the direction of travel. The side unloading door is provided with a connecting bracket on its bottom side. The connecting bracket is connected to the door opening drive device. Controlling the door opening drive device can drive the connecting bracket to open or close the side unloading door.

[0005] Preferably, the cargo residue detector 103 is a laser rangefinder. Based on the detection result of the cargo residue detector 103, the lifting device 16 can be triggered to flip the container 10 from a first set angle position to a second set angle position, wherein the second set angle is greater than the first set angle.

[0017] This utility model embodiment provides a novel side-discharge cargo box structure, including: a box body 10, wherein a cargo residue detector 103 is provided inside the box body 10; a side discharge port 11 is provided on the side wall of the box body 10; a side discharge door 12 is provided on the side discharge port 11; the lower end of the side discharge door 12 is hinged to the box body 10, and a plurality of pin structures 13 are provided between the upper end of the side discharge door 12 and the box body 10, wherein the pin structures 13 are used to fix the upper end of the side discharge door 12 when closed; the ratio of the height of the side discharge door 12 to the height of the box body 10 is greater than or equal to 0.6; The upper side wall of the side unloading door 12 is also provided with a telescopic support leg 14, which is used to extend to the ground during unloading to support the side unloading door 12. The box body 10 is provided with a lifting connection part 15 on the upper end of the two outer side walls in the driving direction, and the lifting connection part 15 is connected to the lifting end of the lifting device 16; the lifting device 16 is provided on the lower end of the side of the box body 10 in the driving direction. The side unloading door 12 is provided with a connecting bracket 17 on its bottom side, and the connecting bracket 17 is connected to the door opening drive device 18; controlling the door opening drive device 18 can drive the connecting bracket 17 to open or close the side unloading door 12.

[0018] In specific implementation, such as Figures 1-5 As shown, the novel side-unloading cargo box structure includes a box body 10, within which a cargo residue detector 103 is installed. The cargo residue detector 103 includes, but is not limited to, visual sensors and distance sensors. The side wall of the box body 10 is provided with a side unloading port 11 (e.g., ...). Figure 4 As shown), a side unloading door 12 is provided inside the side unloading port 11; the lower end of the side unloading door 12 is hinged to the box body 10, and a number of pin structures 13 are provided between the upper end of the side unloading door 12 and the box body 10 at intervals. The pin structures 13 are used to fix the upper end of the side unloading door 12 when it is closed; the ratio of the height of the side unloading door 12 to the height of the box body 10 is greater than or equal to 0.6, so as to increase the height of the side unloading door 12, expand the unloading opening area, and guide the goods to a position far enough away from the wheels for unloading during unloading. Compared with some existing vehicles that have separate deflectors, it can greatly increase the deflection distance, thereby avoiding the problem of wheels getting stuck to the ground to the greatest extent. The upper side wall of the side unloading door 12 is also provided with telescopic support legs 14. The telescopic support legs 14 include, but are not limited to, hydraulic cylinders, telescopic motors, etc. The free end of the telescopic support legs 14 is used to extend to the ground during unloading to support the side unloading door 12, thereby avoiding the problem of vehicle rollover. The upper ends of the two outer side walls of the housing 10 in the driving direction are provided with lifting connection parts 15, which are connected to the lifting end of the lifting device 16; the lifting device 16 is a hydraulic cylinder, etc., and is located on the chassis support at the lower end of the side of the housing 10 in the driving direction (e.g., Figure 1(As shown); by setting the lifting device 16 on the outer wall of the box 10, the lifting device 16 can be avoided from occupying the cargo box or chassis space. In addition, the structure set on the outer wall of the box facilitates the installation of a lifting device 16 with a longer telescopic stroke, which can increase the side unloading angle of the cargo box 10 to 60°. With the combination of the above-mentioned telescopic outriggers 14, the side rollover problem caused by the excessive side unloading angle of the cargo box 10 can be effectively avoided, ensuring vehicle safety. The bottom side of the side unloading door 12 is provided with a connecting bracket 17, which is connected to the door opening drive device 18. The door opening drive device 18 includes, but is not limited to, hydraulic cylinders, motors, etc. The door drive device 18 is located on the side of the chassis support (e.g., Figure 1 As shown in the figure, the side unloading door 12 is opened or closed by the door opening drive device 18 driving the connection direct 17.

[0019] Preferably, the aforementioned pin structure 13, telescopic outrigger 14, lifting device 16, and door opening drive device 18 are all connected to the existing vehicle control system (such as the unmanned vehicle autonomous driving system and the vehicle VCU) to achieve automated side unloading.

[0020] The novel side-dumping cargo box structure provided in this embodiment combines a box body, a side-dumping opening, a side-dumping door, a latch structure, telescopic outriggers, a lifting connection, a lifting device, a connecting bracket, and a door opening drive device. By placing the lifting device on the outside of the box body, it avoids occupying space in the cargo box or chassis structure and provides a larger lifting and telescopic space, increasing the rotation angle of the cargo box along the hinge. By using the large side-dumping door as a deflector to guide the cargo away from the wheels during unloading, it greatly reduces the problem of wheels getting stuck. Furthermore, the latch structure securely fixes the upper end of the side-dumping door. The telescopic outriggers on the side-dumping door support the door during side unloading, preventing tipping and ensuring vehicle safety.

[0021] The novel side-unloading cargo box structure provided by this utility model optimizes the layout of the lifting device to improve lifting performance and space utilization. At the same time, by using the relatively high side-unloading door as a guide plate during unloading, the cargo can be guided to a distance away from the wheels, which greatly alleviates the phenomenon of wheels being buried during side unloading. Furthermore, by integrating the side-unloading door and its telescopic outriggers, the unloading guidance and operational safety are improved.

[0022] Furthermore, the cargo residue detector 103 is a laser rangefinder. Based on the detection result of the cargo residue detector 103, the lifting device 16 can be triggered to flip the container 10 from a first set angle position to a second set angle position, wherein the second set angle is greater than the first set angle.

[0023] In specific implementation, such as Figure 1As shown, the cargo residue detector 103 is a laser rangefinder. The laser rangefinder is connected to the existing vehicle control system. It is mounted on the support frame (a hollow structure) of the container 10 above the side unloading door 11, or it can be directly installed inside the container 10. The actual installation location is determined as needed and will not be elaborated here. The laser rangefinder monitors whether the cargo in the corners of the container 10 has been completely unloaded. When the container 10 is flipped to a first set angle, and the laser rangefinder detects that there is still cargo inside the container 10, it triggers the lifting device 16 to flip the container 10 to a second set angle. The second set angle is greater than the first set angle. Specifically, the first set angle is 45°, and the second set angle is 60°. These angles are only used for distance description and do not limit this solution. In this embodiment, by using a laser rangefinder as the cargo residue detector 103 and flexibly installing it on the support frame (hollow structure) of the container 10 above the side unloading door 11 or inside the container 10, high-precision, non-contact monitoring of cargo residue in the corners of the container 10 is achieved. Once the container 10 is flipped to the first set angle, the laser rangefinder can accurately detect any unloaded goods and automatically trigger the lifting device 16 to flip the container 10 further to the second set angle. This effectively ensures the thoroughness of the unloading, avoids errors and inefficiencies associated with manual inspection, and improves the automation and reliability of the unloading process. It is suitable for various loading and unloading scenarios and solves the problem of some goods being difficult to unload, resulting in cargo residue.

[0024] In specific implementation, such as Figure 3 As shown, the connecting bracket 17 has a triangular structure. Its first corner 171 is connected to the hinge axis of the side unloading port 11 and the housing 10, and its second corner 172 is connected to the side wall of the side unloading door 12. The ratio of the distance between the second corner 172 and the bottom of the side unloading door 12 to the height of the side unloading door 12 is greater than or equal to 0.45. Its third corner 173 is hinged to the telescopic end of the door opening drive device 18. In this embodiment, the triangular structure design provides a stable force transmission path, so that the force of the door opening telescopic device is applied to the side unloading door more evenly, ensuring that the door opens smoothly and reliably, and reducing the risk of jamming. Furthermore, the ratio of the distance between the second corner and the bottom of the side unloading door to the door height is ≥0.45, which optimizes the installation position of the door opening drive device, ensures sufficient lever arm length, makes the side unloading door easy to open in the lifted state, reduces the force required to open the door, and improves the convenience of operation.

[0025] In specific implementation, such as Figure 1 , Figure 2 As shown, the pin structure 13 includes a plurality of pin cylinders 131 and a plurality of pin seats 132, wherein: Several pin-type hydraulic cylinders 131 are arranged downward along the side wall of the housing 10; A pin seat 132 is provided on the upper side wall of the side unloading door 12 at a position corresponding to the pin cylinder 131; when the free end of the pin cylinder 131 is inserted into the pin seat 132, the upper end of the side unloading door 12 is fixed. In this embodiment, the automatic locking and unlocking of the upper end of the side unloading door can be realized by the cooperation of the pin cylinder and the pin seat. When the free end of the pin cylinder is inserted into the pin seat, it provides a firm fixation, ensuring the sealing and safety of the side unloading door during transportation; it can be quickly released during unloading, improving the degree of automation of the operation and reducing manual operation time.

[0026] In specific implementation, such as Figure 5 As shown, the telescopic end of the telescopic outrigger 14 is provided with a foot pad 141. Preferably, the foot pad 141 is hinged to the telescopic end of the telescopic outrigger 14. In this embodiment, the foot pad is hinged to the end of the telescopic outrigger, so that the foot pad can adapt to uneven ground, increase the contact area between the outrigger and the ground, and improve the support stability. Especially in soft or sloping ground, it effectively prevents the outrigger from sinking or sliding, and further enhances the safety during the unloading process.

[0027] In specific implementation, such as Figure 1 As shown, a 360° panoramic camera 101 is provided around the vehicle body 10. In this embodiment, the 360° panoramic camera is located around the sides of the vehicle body, providing all-around field of vision monitoring, especially during unloading, it can observe the surrounding environment of the vehicle in real time.

[0028] In specific implementation, such as Figure 1 As shown, a lighting lamp 102 is provided on the side wall of the box 10 above the side unloading port 11. In this embodiment, the lighting lamp is located above the side unloading port, which can provide local lighting at night or in low light conditions, making the unloading process clearly visible, facilitating operators to monitor the slippage of goods, ensuring thorough unloading, and reducing operational errors and safety hazards.

[0029] This utility model also provides a vehicle that adopts the novel side-dumping cargo box structure described above.

[0030] 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.
