Description

Technical Field

[0001] This application relates to the field of vehicle cargo box technology, and in particular to a vehicle cargo box tipping system and an all-terrain vehicle. Background Technology

[0002] Currently, the cargo box structure of most all-terrain vehicles (UTVs) on the market is composed of components such as gas springs, limit ropes, and locking mechanisms. Several problems exist when tipping the cargo box. First, the locking mechanism must be manually released to tip the cargo box over. Second, the force of the gas springs is limited; if the cargo box is slightly heavy, the user needs to manually assist with the tipping, and if the cargo is too heavy, users with less strength may not be able to complete the tipping. On the other hand, if a stronger gas spring is used, it makes retracting the cargo box extremely difficult, severely impacting the user experience. Furthermore, after prolonged exposure to severe vibrations, the locking mechanism may cause the cargo box to come loose. At high speeds or in complex road conditions, a loose cargo box can easily cause the entire vehicle to tilt or even tip over. Utility Model Content

[0003] To address at least one of the problems mentioned in the background art, this application provides a vehicle cargo box tilting system and an all-terrain vehicle, which can improve the convenience and safety of cargo box tilting.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] In a first aspect, this application provides a vehicle cargo box tipping system, including a frame, a cargo box and an electric push rod. The frame is connected to the front and rear of the vehicle, the cargo box is disposed on the frame, the bottom of the cargo box includes a first hinge portion and a second hinge portion arranged sequentially from front to back, the frame has a third hinge portion, and the third hinge portion is located between the first hinge portion and the second hinge portion in the front-rear direction of the cargo box.

[0006] The first hinge is hinged to the frame, the first end of the electric push rod along its own extension and retraction direction is hinged to the second hinge, and the second end of the electric push rod along its own extension and retraction direction is hinged to the third hinge, so that the cargo box can be rotated around the first hinge by the extension and retraction of the electric push rod, wherein the front of the cargo box is the direction in which the cargo box faces the front of the vehicle.

[0007] As an optional implementation, a control unit is also included. The control unit and the electric push rod are electrically connected. The control unit is located on one side of the cargo box to control the extension and retraction of the electric push rod.

[0008] As an optional implementation, the electric linear actuator includes a motor and a actuator mechanism, with a first end of the actuator mechanism hinged to a second hinge portion, a second end of the actuator mechanism hinged to a third hinge portion, and the motor disposed at the first end of the actuator mechanism.

[0009] As an alternative implementation, the ratio of the distance from the first hinge point to the front end of the cargo box to the front-to-back length of the cargo box is between 0.3 and 0.4.

[0010] As an alternative implementation, the portion of the first articulated part extending to the front end of the cargo box extends from the front end of the frame to be suspended relative to the frame.

[0011] As an alternative implementation, the frame includes a crossbeam extending along the width of the cargo box, with a third hinged portion located on the crossbeam.

[0012] As an alternative implementation, the third hinge portion is offset at one end of the crossbeam.

[0013] As an optional implementation, a connecting wire is also included, with one end electrically connected to the motor and the second end electrically connected to the vehicle's battery, and the section of the connecting wire near the motor extending along the bottom of the cargo box.

[0014] As an optional implementation, there are two electric push rods, which are symmetrically arranged along the width direction of the cargo box.

[0015] Secondly, this application also provides an all-terrain vehicle, including the vehicle cargo box tipping system of the first aspect.

[0016] The vehicle cargo box tipping system provided in this application includes a frame, a cargo box, and an electric push rod. The frame is connected to the front and rear of the vehicle, and the cargo box is mounted on the frame. The bottom of the cargo box includes a first hinge portion and a second hinge portion arranged sequentially from front to back. The frame has a third hinge portion, which is located between the first and second hinge portions along the front-rear direction of the cargo box. The first hinge portion is hinged to the frame, and the first end of the electric push rod along its extension and retraction direction is hinged to the second hinge portion, and the second end of the electric push rod along its extension and retraction direction is hinged to the third hinge portion, so that the extension and retraction of the electric push rod drives the cargo box to tip around the first hinge portion, wherein the front of the cargo box faces the front of the vehicle.

[0017] The vehicle cargo box tipping system provided in this application changes the tipping drive method by replacing traditional gas springs and other components with an electric push rod. The electric push rod is hinged at both ends along its extension direction to the second hinge point of the cargo box and the third hinge point of the vehicle frame, respectively. Furthermore, along the front-rear direction of the cargo box, the third hinge point is located between the first and second hinge points. This layout makes the structure more compact and occupies less space. Based on this, this design eliminates the need for manually releasing complex locking mechanisms; it is directly controlled by the electric push rod, solving the problem of cumbersome manual operation in existing technologies. Moreover, the electric push rod has strong driving force, easily driving the tipping of heavy-duty cargo boxes, avoiding situations where users need to assist with tipping or even fail to tip the cargo box due to insufficient gas spring force. At the same time, this more reliable drive method also reduces the risk of cargo box disengagement due to component vibration, thereby effectively improving the convenience and safety of cargo box tipping.

[0039] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0040] Currently, the cargo box structure of most all-terrain vehicles (UTVs) on the market is composed of components such as gas springs, limit ropes, and locking mechanisms. When tipping the cargo box, the locking mechanism must be manually released to achieve this. Secondly, the force of the gas springs is limited; if the cargo box is even slightly heavy, the user needs to manually assist with the tipping, and if the cargo is too heavy, users with less strength may not be able to complete the tipping operation. Furthermore, after prolonged exposure to severe vibrations, the locking mechanism may cause the cargo box to come loose, easily leading to the vehicle tilting up or even tipping over.

[0041] In view of this, this application provides a vehicle cargo box tipping system, including a frame, a cargo box, and an electric push rod. The frame is connected to the front and rear of the vehicle, and the cargo box is mounted on the frame. The bottom of the cargo box includes a first hinge portion and a second hinge portion arranged sequentially from front to back. The frame has a third hinge portion, which is located between the first and second hinge portions along the longitudinal direction of the cargo box. The first hinge portion is hinged to the frame, and the first end of the electric push rod along its extension direction is hinged to the second hinge portion, and the second end of the electric push rod along its extension direction is hinged to the third hinge portion. The third hinge portion being located between the first and second hinge portions makes the structure more compact and occupies less space. Furthermore, this design eliminates the need for manually releasing a complex locking mechanism; it is directly controlled by the electric push rod, solving the problem of cumbersome manual operation in the prior art. Moreover, the electric push rod has strong driving force, easily driving the tipping of a heavy-load cargo box, avoiding situations where the gas spring force is insufficient, requiring user assistance or even preventing tipping altogether. At the same time, this more reliable drive method also reduces the risk of the cargo box becoming unlocked due to component vibration, thereby effectively improving the convenience and safety of cargo box tipping.

[0043] You can refer to this. Figures 1 to 4This application provides a vehicle cargo box tilting system 100, including a frame 110, a cargo box 120, and an electric push rod 130. The frame 110 is connected to the front and rear of the vehicle, and the cargo box 120 is disposed on the frame 110. The bottom of the cargo box 120 includes a first hinge portion 121 and a second hinge portion 122 arranged sequentially from front to back. The frame 110 has a third hinge portion 111, and along the front-rear direction of the cargo box 120, the third hinge portion 111 is located at... Between the first hinge portion 121 and the second hinge portion 122; the first hinge portion 121 is hinged to the frame 110, the first end of the electric push rod 130 along its own extension and retraction direction is hinged to the second hinge portion 122, and the second end of the electric push rod 130 along its own extension and retraction direction is hinged to the third hinge portion 111, so as to drive the cargo box 120 to rotate around the first hinge portion 121 by the extension and retraction of the electric push rod 130, wherein the front of the cargo box 120 is the direction in which the cargo box 120 faces the front of the vehicle.

[0044] The vehicle cargo box tipping system 100 provided in this application changes the tipping drive method of the cargo box 120 by replacing traditional gas springs and other components with an electric push rod 130. The electric push rod 130 is hinged at both ends along its extension direction to the second hinge portion 122 of the cargo box 120 and the third hinge portion 111 of the frame 110, respectively. Furthermore, along the front-rear direction of the cargo box 120, the third hinge portion 111 is located between the first hinge portion 121 and the second hinge portion 122. This layout makes the structure more compact and occupies less space. Based on this, this design eliminates the need for manually releasing complex locking mechanisms; it is directly controlled by the electric push rod 130, solving the problem of cumbersome manual operation in the prior art. Moreover, the electric push rod 130 has strong driving force, easily driving the tipping of the heavily loaded cargo box 120, avoiding situations where users need to assist with tipping or even cannot tip it due to insufficient gas spring force. At the same time, this more reliable drive method also reduces the risk of the cargo box 120 disengaging due to component vibration, thereby effectively improving the convenience and safety of tipping the cargo box 120.

[0045] In the above embodiments, a control unit 140 may also be included. The control unit 140 is electrically connected to the electric push rod 130. The control unit 140 is located on one side of the cargo box 120 to control the extension and retraction of the electric push rod 130. By adding the control unit 140, operators can easily control the extension and retraction of the electric push rod 130 without having to approach the cargo box 120's tilting area, greatly improving operational convenience and safety. Moreover, the location of the control unit 140 allows operators to quickly locate and operate it, reducing operation time and complexity, and improving work efficiency. Furthermore, this centralized control method helps to achieve precise control of the cargo box 120 tilting process, making the entire system more stable and reliable, and further optimizing the overall performance of the vehicle cargo box tilting system 100.

[0046] In the above embodiments, the electric push rod 130 may include a motor 131 and a push rod mechanism 132. The first end of the push rod mechanism 132 is hinged to the second hinge portion 122, and the second end of the push rod mechanism 132 is hinged to the third hinge portion 111. The motor 131 is disposed at the first end of the push rod mechanism 132. This integrated layout of the motor 131 and the push rod mechanism 132, with the motor 131 disposed at the end of the push rod mechanism 132 near the second hinge portion 122 of the cargo box 120, allows the overall structure of the electric push rod 130 to be more compact, reducing the space occupied around the vehicle cargo box 120 and improving its adaptability to the overall spatial layout of the system. On the other hand, the first end being close to the cargo box 120 and relatively high in position effectively improves the waterproof performance of the motor 131 when the cargo box 120 is in an environment where it may be exposed to water, significantly reducing the risk of water damage to the motor 131 and enhancing the reliability and durability of the entire vehicle cargo box tipping system 100 under complex working conditions. Among them, the motor 131 directly drives the push rod mechanism 132 as a power source. The close integration of the two can reduce the loss in the power transmission process, improve the energy utilization efficiency, ensure that the extension and retraction action of the push rod mechanism 132 is more responsive and the driving force is transmitted more directly, thereby ensuring that the power output is stable and reliable when the cargo box 120 is overturned.

[0047] In the above embodiments, the ratio of the distance between the first hinge portion 121 and the front end of the cargo box 120 to the front-to-back length of the cargo box 120 can be between 0.3 and 0.4. This optimizes the lever arm distribution during the tilting of the cargo box 120, effectively reducing the drive load during the electric push rod 130's operation. This ensures that the cargo box 120 maintains the effortless and smooth tilting motion even under load, avoiding power waste or tilting jamming caused by an unreasonable lever arm. Simultaneously, this position balances the weight distribution between the front and rear ends of the cargo box 120, reducing the swaying amplitude of the cargo box 120 during tilting and improving overall stability. Especially in complex road conditions, this reduces safety risks caused by center of gravity shift, further enhancing the reliability and practicality of the vehicle cargo box tilting system 100.

[0048] In the above embodiment, the portion from the first hinge 121 to the front end of the cargo box 120 extends from the front end of the frame 110, thus being suspended relative to the frame 110. This suspended portion of the cargo box 120 expands its effective load-bearing area, especially when transporting longer goods. It avoids the problem of goods being unable to be loaded due to the length limitation of the frame 110, improving the loading flexibility and applicability of the cargo box 120. Simultaneously, this arrangement ensures that the front end of the cargo box 120 does not structurally interfere with the front end of the frame 110 during the flipping process, providing ample space for the cargo box 120 to flip around the first hinge 121, ensuring a smoother flipping process and reducing the risk of mechanical collisions. In addition, the weight distribution of the suspended part is in a reasonable proportion with the overall cargo box 120. Combined with the position parameters of the first hinge part 121, the mechanical balance during the flipping can be further optimized, so that the driving force of the electric push rod 130 can be used more efficiently. This indirectly enhances the stability and labor-saving of the cargo box 120 during flipping, and provides more reliable structural support for the vehicle to operate under complex conditions.

[0049] In the above embodiment, the frame 110 may include a crossbeam 112 extending along the width direction of the cargo box 120, with the third hinge portion 111 located on the crossbeam 112. It is understood that the crossbeam 112, as an important load-bearing component of the frame 110, provides more stable and balanced support due to its extension along the width direction of the cargo box 120. Positioning the third hinge portion 111 here allows the driving force transmitted by the electric push rod 130 to be more evenly distributed throughout the frame 110 via the crossbeam 112, avoiding structural damage caused by localized stress concentration and enhancing the structural strength and durability of the system. Simultaneously, the positional layout of the crossbeam 112 is adapted to the width direction of the cargo box 120, ensuring that the third hinge portion 111 and the first and second hinge portions 122 form a reasonable force distribution in space. Combined with the extension and retraction of the electric push rod 130, this makes the force on the cargo box 120 more stable during tilting, reducing swaying or jamming caused by uneven force distribution, and further improving the stability and reliability of the cargo box 120 tilting process. In addition, this design, which integrates the key hinge components into the crossbeam 112, also helps to simplify the connection structure between the frame 110 and the cargo box 120 tipping system, improves the overall compactness of the layout, and leaves more space for the installation of other vehicle components.

[0050] In the above embodiment, the third hinge portion 111 can be offset at one end of the crossbeam 112. It is understood that this offset setting allows for flexible adjustment of the point of application of the electric push rod 130's driving force according to the load distribution characteristics of the cargo box 120. This enables the cargo box 120 to achieve dynamic balance through force offset during the flipping process, especially when the center of gravity of the cargo is biased to one side. This reduces unilateral overload caused by the center of gravity shift, avoids wear and tear on structural components due to long-term unbalanced stress, and further optimizes the system's stress rationality. Furthermore, within the limited space of the vehicle, other structures (such as pipes, lines, or supports) that may exist in the middle of the crossbeam 112 can be avoided, reducing spatial interference between components and reserving more space for the installation and operation of the electric push rod 130, thus improving the flexibility and compatibility of the overall system layout.

[0051] In the above embodiments, a connecting wire may also be included. The first end of the connecting wire is electrically connected to the motor 131, and the second end is electrically connected to the vehicle's battery. A section of the connecting wire near the motor 131 extends along the bottom of the cargo box 120. This design ensures a stable power transmission path between the motor 131 and the battery, providing continuous and reliable energy support for the drive of the electric push rod 130 and guaranteeing the stable operation of the cargo box 120's tilting motion. The fact that the connecting wire extends along the bottom of the cargo box 120 near the motor 131 fully utilizes the space at the bottom of the cargo box 120, avoiding the clutter caused by haphazard wiring in other parts of the vehicle, reducing the risk of entanglement or interference with other vehicle components, and improving the overall neatness of the system wiring. Simultaneously, this extension along the bottom of the cargo box 120 provides some protection to the wiring from the bottom structure of the cargo box 120, reducing the possibility of damage to the wiring due to external collisions, friction, or other factors, enhancing the safety and durability of the circuit system, and further ensuring the stable operation of the vehicle cargo box tilting system 100.

[0052] like Figure 4As shown in the above embodiment, there may be two electric push rods 130, which are symmetrically arranged along the width direction of the cargo box 120. This symmetrical arrangement enables the two electric push rods 130 to generate a balanced driving torque when driving the cargo box 120 to tilt, effectively avoiding tilting or jamming of the cargo box 120 due to excessive force on one side, ensuring that the cargo box 120 remains stable during the tilting process. Especially when the cargo box 120 is heavily loaded or the cargo is unevenly distributed, it can significantly improve the stability and safety of the tilting action. Furthermore, the two symmetrically arranged electric push rods 130 can share the weight of the cargo box 120 and the load generated during tilting, reducing the force load on a single electric push rod 130, reducing component wear caused by long-term overload, extending the service life of the electric push rods 130, and thus improving the durability of the entire vehicle cargo box tilting system 100. Secondly, the symmetrical layout is compatible with the width of the cargo box 120, allowing it to better integrate into the overall system structure. It forms a coordinated force transmission path with the hinge points of the frame 110 and the cargo box 120, enabling the driving force to act more efficiently on the cargo box 120, optimizing energy transfer efficiency, and providing more reliable power support for the cargo box 120's tipping. Furthermore, this design facilitates later maintenance and repair; the symmetrical structure makes component replacement or debugging more consistent, improving the system's maintainability.

[0053] Furthermore, this application embodiment also provides an all-terrain vehicle, including the vehicle cargo box tilting system 100 in the above embodiment. The vehicle cargo box tilting system 100 includes a frame 110, a cargo box 120, and an electric push rod 130. The frame 110 is connected to the front and rear of the vehicle, and the cargo box 120 is disposed on the frame 110. The bottom of the cargo box 120 includes a first hinge portion 121 and a second hinge portion 122 arranged sequentially from front to back. The frame 110 has a third hinge portion 111, and in the front-rear direction of the cargo box 120, the third hinge portion 111 is located between the first hinge portion 121 and the second hinge portion 122. The first hinge portion 121 is hinged to the frame 110, and the first end of the electric push rod 130 along its own extension and retraction direction is hinged to the second hinge portion 122, and the second end of the electric push rod 130 along its own extension and retraction direction is hinged to the third hinge portion 111. The third hinge portion 111 is located between the first hinge portion 121 and the second hinge portion 122. This layout makes the structure more compact and occupies less space. Furthermore, this design eliminates the need for manually releasing the complex locking mechanism; it is directly controlled by the electric push rod 130, solving the problem of cumbersome manual operation in existing technologies. The electric push rod 130 also provides strong driving force, easily driving the heavy-duty cargo box 120 to tilt, avoiding situations where insufficient gas spring force requires user assistance or even prevents tilting. Simultaneously, this more reliable driving method reduces the risk of the cargo box 120 disengaging due to component vibration, thus effectively improving the ease of tilting the cargo box 120 and vehicle safety.
