[0032] In the prior art, the cargo box flip seat of a three-sided flip dump truck generally adopts a manual latch structure. The personnel in the vehicle cannot accurately obtain the pin shaft status. When the cargo box is lifted, there is a problem of missing the pin shaft, resulting in deformation of components such as the hydraulic cylinder, cargo box and subframe due to instantaneous impact. After the cargo box falls back, there is a problem of missing the pin shaft, resulting in a large degree of shaking of the cargo box when the vehicle is driving on bumpy roads, causing safety accidents. In addition, when the cargo box is switched from a flat state to a lifted state, the pin shaft needs to be completely pulled out, which is inconvenient to operate.

[0033] Reference below Figure 1-Figure 6 The cargo box turning mechanism according to the embodiment of the utility model is described.

[0034] According to the utility model, the cargo box flipping mechanism 1 includes a subframe flip seat 11; a bracket body 12, the bracket body 12 is connected to the cargo box 10 and is suitable for cooperating with the subframe flip seat 11; a first locking member 13, the first locking member 13 is rotatably arranged on the bracket body 12 to switch between a locked state and an unlocked state, in which at least a part of the first locking member 13 is arranged on a side of the subframe flip seat 11 away from the bracket body 12 to limit the subframe flip seat 11 from disengaging from the bracket body 12; a second locking member 14, the second locking member 14 is movably arranged on the bracket body 12 and has a first state and a second state, in the first state, the second locking member 14 cooperates with the bracket body 12 to limit the rotation of the first locking member 13, and in the second state, the second locking member 14 disengages from the bracket body 12, and the first locking member 13 can rotate relative to the bracket body 12; a sensor 16, the sensor 16 is arranged on the bracket body 12 and is suitable for detecting whether the first locking member 13 is in an unlocked state.

[0035] Specifically, the bracket body 12 is arranged at the bottom of the cargo box 10, specifically on both sides of the width direction of the bottom of the cargo box 10. Multiple bracket bodies 12 can be arranged at intervals on each side of the width direction of the bottom of the cargo box 10. Multiple subframe flip seats 11 are correspondingly arranged on the subframe 111, and a pushing rod 113 can be arranged in the middle position of the subframe 111 to push the cargo box 10 to flip.

[0036] The bracket body 12 is provided with a first locking member 13 and a second locking member 14. The first locking member 13 is rotatably provided on the bracket body 12 and has a locked state and an unlocked state. The locked state of the first locking member 13 is as follows: Figure 1 and Figure 2 As shown, at least a portion of the first locking member 13 is located on the side of the sub-frame flip seat 11 away from the bracket body 12, and the other portion of the first locking member 13 cooperates with the bracket body 12 to lock the bracket body 12 and the sub-frame flip seat 11 in the flipping direction of the cargo box 10 to prevent the bracket body 12 from separating from the sub-frame flip seat 11, wherein, if the cargo box 10 is in a flat state, the first locking members 13 on multiple bracket bodies 12 are all in a locked state, restricting the bracket body 12 from separating from the sub-frame flip seat 11 to prevent the cargo box 10 from flipping or shaking violently during the operation of the vehicle; when the cargo box 10 needs to be flipped, for example, the cargo box 10 needs to be flipped toward one side in the width direction, the multiple first locking members 13 located on one side in the width direction of the cargo box 10 are all in a locked state, and the multiple first locking members 13 located on the other side are all in an unlocked state, and the multiple bracket bodies 12 on one side in the width direction of the cargo box 10 can be rotated relative to the multiple sub-frame flip seats 11, thereby realizing the flipping of the cargo box 10.

[0037] The second locking member 14 has a first state. In the first state, the second locking member 14 can cooperate with the bracket body 12 to limit the first locking member 13 from rotating relative to the bracket body 12. When the first locking member 13 is in the locked state, the second locking member 14 cooperates with the first locking member 13 and the bracket body 12 to limit the first locking member 13 from rotating and limiting the bracket body 12 from separating from the sub-frame flip seat 11; when the first locking member 13 is rotated to the unlocked state, the second locking member 14 cooperates with the bracket body 12 to fix the first locking member 13 in the unlocked state to avoid affecting the flipping of the cargo box 10 when the first locking member 13 is rotated to the locked state; in the second state, the second locking member 14 is disengaged from the bracket body 12, and the first locking member 13 can be rotated to the unlocked state. When the first locking member 13 is rotated to the unlocked state, the second locking member 14 can be restored to the first state and limit the first locking member 13 from rotating to the locked state.

[0038] A sensor 16 is provided on the bracket body 12, and the sensor 16 can timely and accurately detect whether the first locking member 13 is in an unlocked state and provide feedback to the occupants. The occupants can accurately know the installation status of the cargo box 10 and the subframe 111 to ensure the safe operation of the vehicle.

[0039] According to the utility model, the cargo box flipping mechanism 1 is provided with a first locking member 13 and a second locking member 14 on the bracket body 12. The first locking member 13 and the second locking member 14 cooperate to control the locking and unlocking of the bracket body 12 and the sub-frame flip seat 11. In addition, a sensor 16 is provided on the bracket body 12 to accurately obtain the locking state and unlocking state of the first locking member 13, thereby realizing intelligent control of the cargo box 10 and ensuring the safe use of the cargo box 10.

[0040] According to some embodiments of the present invention, the first locking member 13 includes a pivot portion 131 and a stop portion 132. The pivot portion 131 is rotatably disposed on the bracket body 12 and has the same extension direction as the bracket body 12 in the locked state; the stop portion 132 is disposed at the first end of the pivot portion 131 and is orthogonal to the extension direction of the pivot portion 131. When the first locking member 13 is rotated to the locked state, the stop portion 132 is located on the side of the sub-frame flip seat 11 away from the bracket body 12.

[0041] Specifically, the stopper 132 is disposed at the first end of the pivoting portion 131, the first end may be an end of the pivoting portion 131 facing the bottom, and the extending direction of the stopper 132 is orthogonal to the extending direction of the pivoting portion 131. Figure 1 As shown, the pivoting portion 131 can be configured as a rotating rod, a pivot shaft can be provided on the bracket body 12, the rotating rod can rotate around the pivot shaft, and the stopper 132 is provided at the bottom of the rotating rod and can be configured as follows Figure 1In the U-shaped structure shown, the pivot portion 131 can rotate relative to the bracket body 12 to drive the stop portion 132 to rotate, thereby realizing the switching of the first locking member 13 between the locked state and the unlocked state, wherein, when the first locking member 13 rotates to the unlocked state, the stop portion 132 is located on the side of the sub-frame flip seat 11 away from the bracket body 12 to limit the bracket body 12 from separating from the sub-frame flip seat 11.

[0042] In some embodiments, a handle 1321 is provided on the stopper portion 132 , and the handle 1321 can drive the first locking portion to rotate relative to the bracket body 12 .

[0043] According to some embodiments of the utility model, the sensor 16 is arranged on the outer periphery of the bracket body 12, and the second end of the pivot portion 131 is provided with a sensing end 134. After the pivot portion 131 rotates to the unlocked position, the sensing end 134 is opposite to the sensor 16 to determine that the first locking member 13 is in the unlocked state.

[0044] like Figure 2 As shown, a sensing end 134 is provided on the pivoting part 131. When the first locking member 13 rotates to the unlocked state, the sensing end 134 faces the sensor 16. The sensor 16 detects that the first locking member 13 is in the unlocked state and gives feedback to the occupants. When the cargo box 10 needs to be lifted but the corresponding first locking member 13 is detected to be in the locked state, the occupants can adjust the first locking member 13 according to the feedback signal of the sensor 16 to ensure the safe lifting of the cargo box 10 and avoid the first locking member 13 being damaged by the lifting of the cargo box 10 when it is in the locked state. When the cargo box 10 is in the flat state, the occupants can adjust the first locking member 13 in the unlocked state according to the feedback result of the sensor 16 to avoid the cargo box 10 shaking when the vehicle is driving. The present application sets the sensing end 134 on the pivoting part 131 to cooperate with the sensor 16, so that the occupants can obtain the connection state between the cargo box 10 and the subframe 111 in a timely and accurate manner, thereby improving the safety of the vehicle.

[0045] According to some embodiments of the utility model, the sensor 16 is constructed as a magnetic induction sensor, which cooperates with the sensing end 134 to feedback an electrical signal to the occupants of the vehicle to feedback the locking status of the first locking member 13. The magnetic induction sensor is easy to use, and the detection results are accurate and timely, providing more intelligent control conditions for the occupants of the vehicle.

[0046] According to some embodiments of the present invention, one end of the bracket body 12 is open and formed with a support groove 121 , and a ball head 112 is formed on the sub-frame flip seat 11 . The ball head 112 is received in the support groove 121 to cooperate with the sub-frame flip seat 11 .

[0047] like Figure 1As shown, one end of the bracket body 12 facing the sub-frame flip seat 11 is open and forms a support groove 121. The ball head 112 is accommodated in the support groove 121, which facilitates the bracket body 12 to flip around the ball head 112. The outer surface of the ball head 112 fits tightly with the inner wall of the support groove 121, increasing the contact area between the ball head 112 and the support groove 121. The bracket body 12 rotates stably around the ball head 112 to avoid collision between the ball head 112 and the support groove 121 to generate noise.

[0048] According to some embodiments of the utility model, the cargo box flipping mechanism 1 also includes a limiting bracket 15, which is arranged on the bracket body 12, and a second locking member 14 is movably arranged on the limiting bracket 15 along the radial direction of the bracket body 12; in a first state, the second locking member 14 extends into the bracket body 12 and an end portion protrudes from the outer surface of the bracket body 12; in a second state, the second locking member 14 is accommodated in the bracket body 12 and an end portion does not protrude from the outer surface of the bracket body 12.

[0049] like Figure 4 As shown, by arranging a limiting bracket 15 on the bracket body 12, the limiting bracket 15 supports the second locking member 14 to ensure that the second locking member 14 can move stably relative to the bracket body 12; when the second locking member 14 moves to the first state, the end of the second locking member 14 protrudes from the outer surface of the bracket body 12 and cooperates with the first locking member 13 to limit the rotation of the first locking member 13 relative to the bracket body 12; when the second locking member 14 moves to the second state, the second locking member 14 cooperates with the limiting bracket 15 to accommodate the end of the second locking member 14 inside the bracket body 12 and does not protrude from the outer surface of the bracket body 12, and the rotation of the first locking member 13 is not restricted. When the first locking member 13 rotates to the unlocked position, the second locking member 14 disengages from the cooperation with the limit and moves to the first state, limiting the rotation of the first locking member 13 and keeping it in the unlocked state.

[0050] According to some embodiments of the present invention, the second locking member 14 is configured as a locking pin, a locking hole 133 is provided on the first locking member 13 , and the second locking member 14 passes through the bracket body 12 and cooperates with the locking hole 133 to limit the movement of the first locking member 13 .

[0051] In the first state, the locking pin passes through the bracket body 12 and protrudes from the outer surface of the bracket body 12. The locking pin passes through the locking hole 133. The first locking member 13 is restricted by the locking pin and cannot rotate relative to the bracket body 12, thereby maintaining the locked state. When the first locking member 13 rotates to the unlocked position, the locking pin protrudes from the outer surface of the bracket body 12 and stops at the outer periphery of the first locking member 13, thereby maintaining the first locking member 13 in the unlocked state, thereby ensuring that the cargo box 10 is safely lifted. The locking pin and the first locking member 13 have a simple structure and are easy to cooperate.

[0052] According to some embodiments of the utility model, an elastic member 142 is arranged between the second locking member 14 and the limiting bracket 15; wherein a limiting boss 151 is arranged on the limiting bracket 15, and a limiting boss 141 is formed on the outer periphery of the second locking member 14, and the second locking member 14 can be selectively rotated until the limiting boss 141 and the limiting boss 151 stop to maintain in the second state.

[0053] Specifically, the elastic member 142 can be constructed as a spring, and the second locking member 14 can drive the limiting protrusion 141 to move to the end of the limiting boss 151 away from the bracket body 12, and rotate until the limiting protrusion 141 and the limiting boss 151 are stopped. At this time, the spring is in a compressed state, and applies a thrust toward the bracket body 12 to the second locking member 14, but due to the obstruction of the limiting boss 151, the second locking member 14 cannot be pushed to the first state by the spring, and always maintains the second state; the second locking member 14 is rotated and the stopping of the limiting protrusion 141 and the limiting boss 151 is released, and the spring can push the second locking member 14 to reset to the first state. By setting the elastic member 142 to cooperate with the limiting bracket 15, the second locking member 14 can be pushed to switch between the first state and the second state according to needs. The structure is simple and easy to use.

[0054] According to some embodiments of the present invention, a limiting rib 152 is disposed at the radial outer end of the limiting bracket 15 , and the limiting rib 152 cooperates with the limiting protrusion 141 to limit the second locking member 14 from being separated from the limiting bracket 15 .

[0055] like Figure 1 As shown, a limiting retaining edge 152 is provided at one end of the limiting bracket 15 away from the bracket body 12. When the second locking member 14 moves to the second state, the second locking member 14 moves along the limiting bracket 15 toward the end away from the bracket body 12. When the second locking member 14 moves to the limiting protrusion 141 and stops with the limiting retaining edge 152, the second locking member 14 cannot continue to move away from the bracket body 12, so as to limit the second locking member 14 from being separated from the limiting bracket 15, avoid the second locking member 14 from falling and needing to be repeatedly installed, and make the second locking member 14 more convenient to use.
