[0038] This application provides a mountain transport vehicle, see reference. Figures 1 to 5 The mountain transport vehicle includes a chassis 10, a cargo box 20, and at least two drive components 30.

[0039] The chassis 10 includes a chassis body 11 and a support assembly 12. The support assembly 12 is disposed on the chassis body 11 and includes at least two support parts 12a.

[0040] The cargo box 20 is rotatably connected to the chassis body 11, and the extension direction of the rotation axis is the first direction, which intersects with the travel direction of the mountain transport vehicle.

[0041] The drive unit 30 connects the chassis 10 and the cargo box 20. At least one support 12a and at least one drive unit 30 are located on one side of the chassis 10 along the first direction, and at least one support 12a and at least one drive unit 30 are located on the other side.

[0042] The drive unit 30 includes a leveling state and a stop state. The drive unit 30 drives the chassis 10 to rotate relative to the cargo box 20 to switch between the leveling state and the stop state.

[0043] In the stationary state, the support part 12a supports the cargo box 20.

[0044] In the leveled state, the cargo box 20 is separated from the support part 12a, and the drive component 30 supports the cargo box 20.

[0045] The chassis body 11 is used to mount other devices for the mountain transport vehicle, such as an engine, hydraulic pump, and control devices. The chassis body 11 includes a running gear to enable the mountain transport vehicle to move. The specific type of running gear is not limited, such as tracks.

[0046] Cargo container 20 is used to store objects that need to be transported.

[0047] The drive unit 30 is used to drive the cargo box 20 to rotate relative to the chassis body 11.

[0048] The leveling state refers to the state in which the drive member 30 applies a force to the chassis 10 and the cargo box 20, causing the cargo box 20 to separate from the support part 12a. In this state, the cargo box 20 is only supported by the drive member 30. Therefore, by changing the magnitude of the supporting force applied by the drive member 30 to the cargo box 20, the angle between the cargo box 20 and the chassis body 11 can be changed.

[0049] When a mountain transport vehicle travels in mountainous areas, the chassis body 11 will pitch and roll as it goes uphill and downhill. If the cargo box 20 pitches and rolls with the chassis body 11, the goods inside the cargo box 20 may slip, collide, or even fall out of the cargo box 20.

[0050] During the operation of the mountain transport vehicle in mountainous areas, the drive unit 30 is in a leveling state. Since the rotation axis between the cargo box 20 and the chassis body 11 intersects with the direction of travel of the mountain transport vehicle, the drive unit 30 continuously changes the angle between the cargo box 20 and the chassis body 11 during the pitch change of the chassis body 11 to adapt to the pitch angle change of the chassis body 11, thereby enabling the cargo box 20 to remain as level as possible and the goods inside the cargo box 20 to remain stable.

[0051] It is understandable that, in the leveling state, the supporting force of the drive component 30 on the cargo box 20 can remain constant so that the angle between the cargo box 20 and the chassis 10 remains unchanged; or the supporting force of the drive component 30 on the cargo box 20 can change continuously, so that the angle between the cargo box 20 and the chassis 10 can change continuously, in order to better adapt to changes in terrain.

[0052] The stopped state refers to the state in which the drive unit 30 stops applying force to the cargo box 20 and the chassis 10, so that the cargo box 20 contacts the chassis 10 under the action of gravity and is supported by the support part 12a. This helps to reduce the force applied by the cargo box 20 to the drive unit 30 and protects the drive unit 30.

[0053] It is understandable that when the mountain transport vehicle is driving or parked on flat ground, the drive unit 30 is in a stopped state.

[0054] The chassis 10 along the first direction means that the chassis 10 is divided into two parts arranged along the first direction and the two parts have the same size along the first direction, one part being one side and the other part being the other side.

[0055] In the leveling state, since one drive member 30 is located on one side of the chassis 10 along the first direction and the other drive member 30 is located on the other side, it is beneficial to make the pitch deformation of the cargo box 20 in the first direction.

[0056] In the stationary state, since one support 12a is located on one side of the chassis 10 along the first direction and the other support 12a is located on the other side, it helps to suppress the torsional deformation of the cargo box 20 in the first direction and reduces the risk of damage to the drive members 30 on different sides of the first direction due to the deformation of the cargo box 20.

[0057] The mountain transport vehicle in this embodiment of the application, by providing support parts 12a on different sides of the chassis 10 along the first direction, is conducive to making the support of the cargo box 20 in the first direction more stable when it is stopped. It is also conducive to reducing the force of the cargo box 20 on the different driving components 30 in the first direction, which helps to reduce the risk of damage to the driving components 30 and improve their service life.

[0058] In some embodiments, the first direction is perpendicular to the direction of travel of the mountain transport vehicle.

[0059] In some embodiments, the direction of travel of the mountain transport vehicle is the length direction of the mountain transport vehicle, and the first direction is the width direction of the mountain transport vehicle.

[0060] Understandably, at least a portion of the cargo box 20 is located on top of the chassis 10 so that the support 12a and the drive unit 30 can support the chassis 10.

[0061] In some embodiments, see Figure 1 , Figure 2 and Figure 4The chassis body 11 is provided with a receiving cavity 11a, the top side of the receiving cavity 11a is at least partially open, at least part of the cargo box 20 is located in the open position of the receiving cavity 11a, and one end of the drive member 30 is connected to the side wall of the receiving cavity 11a along the first direction.

[0062] The receiving cavity 11a is used to receive other devices of the chassis 10, such as the engine, hydraulic pump, control device, etc.

[0063] By placing the drive member 30 on the side wall of the receiving cavity 11a along the first direction, it is beneficial to form a complete space within the receiving cavity 11a to accommodate other devices, thereby reducing the risk of interference between the movement of the drive member 30 and other devices.

[0064] The specific type of the drive component 30 is not limited.

[0065] For example, the driving component 30 is a telescopic hydraulic cylinder. One of the telescopic rod and the lever of the telescopic hydraulic cylinder is hinged to the cargo box 20, and the other is hinged to the chassis body 11. In this way, the relative rotation between the cargo box 20 and the chassis body 11 can be achieved by extending and retracting the telescopic hydraulic cylinder. The driving method is simple and easy to control.

[0066] It is understandable that the hydraulic oil pump is connected to the telescopic cylinder, and the timing and flow rate of the hydraulic oil pump supplying hydraulic oil to the telescopic cylinder are controlled by the control device, so that the telescopic cylinder can switch between the leveling state and the stop state, and the telescopic cylinder can be controlled in the leveling state to fix or change the angle between the cargo box 20 and the chassis body 11.

[0067] It is understandable that the first direction, the vertical direction, and the direction of travel of the mountain transport vehicle intersect each other.

[0068] At least a portion of the drive member 30 is located within the receiving cavity 11a to protect the drive member 30 via the chassis 10 body.

[0069] In some embodiments, see Figure 1 and Figure 2 At least a portion of the support component 12 is located within the receiving cavity 11a.

[0070] In this way, the chassis body 11 can protect the support component 12.

[0071] In some embodiments, see Figure 1 and Figure 2 The support portion 12a is located outside the receiving cavity 11a.

[0072] Thus, in the stopped state, at least a portion of the cargo box 20 supported by the support part 12a is located outside the receiving cavity 11a, reducing the risk of interference between the cargo box 20 and other devices within the receiving cavity 11a.

[0073] In some embodiments, see Figure 1 The cargo box 20 is hinged to the chassis 10, and the hinge position is located at the same end of the two along the direction of travel of the mountain transfer vehicle.

[0074] This helps reduce the risk of interference between the cargo box 20 and the chassis 10 body when the chassis is leveled.

[0075] In some embodiments, the hinged position of the cargo box 20 to the chassis 10 body is located at the edge of the open position of the receiving cavity 11a.

[0076] In some embodiments, see Figure 4 The cargo box 20 is provided with a guide post 40 on the side facing the chassis 10. The guide post 40 extends towards the chassis 10. The chassis 10 is provided with a limiting channel 10a. The limiting channel 10a is open on the side facing the cargo box 20. In the leveling state, at least a part of the guide post 40 passes through the limiting channel 10a. The inner walls of the limiting channel 10a on both sides along the first direction are engaged with the guide post 40 along the first direction.

[0077] The inner walls of the limiting channel 10a on both sides in the first direction restrict the range of motion of the guide post 40 located within the limiting channel 10a in the first direction.

[0078] Thus, in the leveling state, the movement of the guide column 40 is constrained by the inner wall of the limiting channel 10a, which helps to guide the relative rotation of the cargo box 20 and the chassis body 11; the movement of the cargo box 20 relative to the chassis body 11 in the first direction is restricted by the inner wall of the limiting channel 10a along the first direction, which helps to protect the connection position between the cargo box 20 and the chassis body 11 and the drive component 30.

[0079] It is understandable that, in the stopped state, at least a portion of the guide post 40 is located within the limiting channel 10a.

[0080] The number of guide posts 40 can be one or more, and the number of limiting channels 10a that cooperate with the guide posts 40 is the same as the number of guide posts 40.

[0081] The specific method of forming the limiting channel 10a is not limited.

[0082] For example, the limiting channel 10a includes a first channel, which is surrounded by the support component 12 to form the first channel.

[0083] In other words, the first channel is formed entirely by the support component 12 itself, without the need for cooperation with other components.

[0084] This allows for the direct installation of the first channel during the installation of the support component 12, thus improving installation efficiency.

[0085] For example, in some embodiments where the receiving cavity 11a is provided, see [reference]. Figure 4 The limiting channel 10a includes a second channel 10aa, and the support component 12 and the receiving cavity 11a are spaced apart along the side wall in the first direction to jointly enclose and form the second channel 10aa.

[0086] In this way, directly utilizing the inner wall of the receiving cavity 11a to form part of the inner wall of the second channel 10aa helps to simplify the structure of the support assembly 12, making the size of the support assembly 12 more compact and reducing the space occupied by the support assembly 12 in the receiving cavity 11a.

[0087] In some embodiments, see Figure 1 The guide column 40 is located at the end of the cargo box 20 away from its rotatable connection with the chassis body 11, thereby reducing the risk of the guide column 40 interfering with other devices in the chassis 10 during movement.

[0088] In some embodiments where the number of guide posts 40 is multiple, see [reference]. Figure 3 At least some of the guide pillars 40 are arranged along the first direction.

[0089] The specific structural form of the support component 12 is not limited.

[0090] For example, see Figure 4 The support assembly 12 includes a support plate 121 and a column 122. The column 122 is connected to the chassis body 11 and extends in the vertical direction. The support plate 121 is located at the top of the column 122 and forms a support part 12a.

[0091] Thus, through the column 122, the load of the cargo box 20 can be directly transferred to the chassis 10 in the vertical direction when the vehicle is stationary.

[0092] In some embodiments, the chassis body 11 includes multiple reinforcing beams connected to the inner wall of the receiving cavity 11a, and the column 122 is connected to the reinforcing beams. This facilitates the transfer of load to the main load-bearing structure of the chassis body 11 by the column 122 when the chassis is stationary, thereby improving the overall structural strength.

[0093] In some embodiments, there is only one support plate 121, and different parts of the support plate 121 form various support portions 12a. This helps to reduce the number of parts in the mountain transport vehicle.

[0094] In some embodiments, see Figure 4 There are multiple support plates 121, and each support plate 121 forms a corresponding single support part 12a.

[0095] This helps to reduce the size of the support plate 121 and facilitates its installation on the chassis body 11.

[0096] The number of columns 122 that cooperate with the support plate 121 is unlimited; there can be one or more.

[0097] In some embodiments, see Figure 1 and Figure 5 The connection point between the drive unit 30 and the cargo box 20 is located on the side of the cargo box 20 away from the rotational connection point between the cargo box 20 and the chassis body 11 along the direction of travel of the mountain transfer vehicle.

[0098] The side of the cargo box 20 away from the rotatable connection between the cargo box 20 and the chassis body 11 along the direction of travel of the mountain transport vehicle refers to dividing the cargo box 20 along the direction of travel of the mountain transport vehicle into two parts that are arranged along the direction and have the same size along the direction. One part is rotatably connected to the chassis body 11, and the other part is connected to the drive unit 30.

[0099] This helps reduce the force required for the drive component 30 to drive the chassis body 11 to rotate relative to the cargo box 20, and also helps reduce the size of the drive component 30.

[0100] In some embodiments, along the travel direction of the mountain transport vehicle, the connection position between the drive component 30 and the chassis body 11 is located on the side of the connection position between the drive component 30 and the cargo box 20, close to the connection position between the cargo box 20 and the chassis 10.

[0101] This allows for more space to increase the stroke of the drive unit 30, which in turn allows for a wider range of rotation angles between the chassis body 11 and the cargo box 20.

[0102] In some embodiments, the drive members 30 are arranged at relative intervals along a first direction.

[0103] In this way, when the container is leveled, the forces on the container 20 are more balanced in the first direction, reducing the risk of cargo slippage or collision caused by the container 20 twisting and deforming in the first direction.

[0104] Understandably, the lower the center of gravity of a mountain transport vehicle while driving in mountainous terrain, the lower the risk of it overturning or tipping over. Therefore, it is necessary to impose restrictions on the vertical dimensions of mountain transport vehicles.

[0105] In some embodiments, the drive member 30 is arranged at an angle to the vertical direction, which helps to increase the extension and retraction stroke of the drive member 30 while limiting the vertical dimensions of the mountain transport vehicle to lower the center of gravity.

[0106] The various embodiments / implementations provided in this application can be combined with each other without creating contradictions.

[0107] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
