Further, as shown in fig. 6 and 7, the first support rolling mechanism 3 and the second support rolling mechanism 4 further include a rotating unit 8; the rotating unit 8 comprises a support 9, a rotating shaft 10 and a limiting piece 11; the first end of the supporting piece 9 is connected with the bottom surface of the carriage body 1; the second end of the supporting part 9 is connected with the first end of the supporting unit 5 through the rotating shaft 10, so that the supporting unit 5 is rotatably connected with the bottom surface of the wagon box body 1; the limiting part 11 is used for fixing the relative position between the supporting unit 5 and the carriage body 1.
In the above embodiment, the first rolling support mechanism 3 and the second rolling support mechanism 4 are rotatably connected to the bottom surface of the vehicle body 1 through the rotating unit 8. The rotating unit 8 includes a supporting member 9, a rotating shaft 10 and a limiting member 11, a first end of the supporting member 9 is connected to the bottom surface of the car body 1, and specifically, the first end of the supporting member 9 may be fixedly connected to the bottom surface of the car body 1, or detachably connected thereto by a bolt. The second end of the supporting member 9 is away from the bottom surface of the wagon body 1, and a rotating shaft 10 is disposed on the second end, the first end of the supporting unit 5 is connected to the second end of the supporting member 9 through the rotating shaft 10, and the supporting unit 5 can rotate around the rotating shaft 10. In a possible implementation manner, the first preset position and the second preset position may be controlled by the shape of the supporting member 9, for example, the second end of the supporting member 9 is composed of three surfaces, the first surface and the second surface are arranged in parallel, the third surface is connected with the first surface and the second surface, the accommodating space in the middle of the three surfaces is used for the supporting unit 5 to rotate, the rotation direction of the supporting unit 5 is consistent with the direction of the first surface and the second surface, the first surface and the second surface are provided with the limiting protrusion, when the supporting unit 5 rotates to the first preset position, the limiting protrusion fixes the supporting unit 5 at the first preset position, the limiting protrusion is the limiting member 11, and of course, the limiting protrusion corresponding to the second preset position may also be provided, so as to fix the supporting unit 5 at the second preset position. In another possible implementation manner, the limiting member 11 includes a limiting pin, and after the limiting pin is pulled out from the rotating unit, the supporting unit 5 can rotate around the rotating unit 8; after the limiting pin is installed in the rotating unit 8, the relative position between the supporting unit 5 and the bottom surface of the carriage body 1 is fixed. As shown in the left side of fig. 8, the support unit 5 is fixed at a first predetermined position, i.e., when the support unit 5 is perpendicular to the bottom surface of the car body 1, and as shown in the right side of fig. 8, the support unit 5 is fixed at a second predetermined position, i.e., when the support unit 5 is parallel to the bottom surface of the car body 1. It should be noted that the supporting unit 5 may be a single rod-shaped structure, or may be formed by combining a plurality of rod-shaped structures, such as an H-shaped supporting unit 5 or a triangular supporting unit 5, that is, the supporting unit 5 only needs to have a supporting function, and the specific shape structure of the supporting unit 5 is not specifically limited in this embodiment.
Further, the number of the first supporting rolling mechanisms 3 is two, and the first supporting rolling mechanisms are symmetrically arranged on two sides of the bottom surface area of the rear side of the carriage body 1. In order to better support the wagon box body 1 and more conveniently rotate the support unit 5 of the first support rolling mechanism 3, the first support rolling mechanisms 3 are symmetrically arranged on two sides of the bottom surface area of the wagon box body 1 on the rear side. In a possible implementation manner, in order to facilitate the operation of the two first support rolling mechanisms 3, the wagon box further comprises a first connecting mechanism; two ends of the first connecting mechanism are respectively connected with the two first supporting and rolling mechanisms 3, so that the two first supporting and rolling mechanisms 3 rotate simultaneously. That is to say, the supporting unit 5 of the first supporting rolling mechanism 3 on one side of the wagon box can be rotated to drive the supporting unit 5 of the first supporting rolling mechanism 3 on the other side to rotate, that is, when the supporting unit 5 of the first supporting rolling mechanism 3 on one side rotates to the first preset position, the supporting unit 5 of the first supporting rolling mechanism 3 on the other side also rotates to the first preset position, and when the supporting unit 5 of the first supporting rolling mechanism 3 on one side rotates to the second preset position, the supporting unit 5 of the first supporting rolling mechanism 3 on the other side also rotates to the second preset position, so that two first supporting rolling mechanisms 3 can be conveniently controlled. Specifically, the first connecting mechanism may be a rod-like structure connecting from a midpoint of the supporting unit 5 of the first supporting and rolling mechanism 3 on one side to a midpoint of the supporting unit 5 of the first supporting and rolling mechanism 3 on the other side.
Furthermore, the number of the second supporting and rolling mechanisms 4 is two, and the two second supporting and rolling mechanisms are symmetrically arranged on two sides of the bottom surface area on the vehicle head side of the vehicle box body 1. In order to better support the wagon body 1 and to facilitate the rotation operation of the support units 5 of the second support rolling mechanisms 4 at the two sides of the wagon body 1, the second support rolling mechanisms 4 are symmetrically arranged at the two sides of the bottom surface area at the head side of the wagon body 1. In a possible implementation manner, in order to facilitate the operation of the two second support rolling mechanisms 4, the wagon box further comprises a second connecting mechanism; two ends of the second connecting mechanism are respectively connected with the two second supporting and rolling mechanisms 4, so that the two second supporting and rolling mechanisms 4 rotate simultaneously. That is to say, when the supporting unit 5 of the second supporting rolling mechanism 4 on one side of the wagon box is rotated, the supporting unit 5 of the second supporting rolling mechanism 4 on the other side is driven to rotate, namely, when the supporting unit 5 of the second supporting rolling mechanism 4 on one side is rotated to the first preset position, the supporting unit 5 of the second supporting rolling mechanism 4 on the other side is also rotated to the first preset position, and when the supporting unit 5 of the second supporting rolling mechanism 4 on one side is rotated to the second preset position, the supporting unit 5 of the second supporting rolling mechanism 4 on the other side is also rotated to the second preset position, so that the two second supporting rolling mechanisms 4 can be conveniently controlled. Specifically, when the number of the second support rolling mechanisms 4 is two, the number of the first support rolling mechanisms 3 may be two, such as symmetrically disposed on two sides of the bottom surface area of the rear side of the car body 1, or one, such as disposed in the center of the bottom surface area of the rear side of the car body 1, and the two second support rolling mechanisms 4 are triangular, that is, the two second support rolling mechanisms 4 and the first support rolling mechanism 3, the two second support rolling mechanisms 4 and the two second support rolling mechanisms 4 can both support the car body 1. It should be noted that, of course, a greater number of the first supporting and rolling mechanisms 3 or the second supporting and rolling mechanisms 4 may be provided, for example, four first supporting and rolling mechanisms 3 or four second supporting and rolling mechanisms 4, as long as the wagon body 1 can be supported by the first supporting and rolling mechanisms 3 and the second supporting and rolling mechanisms 4.
In a possible implementation manner, the number of the first support rolling mechanisms 3 is one, and the number of the second support rolling mechanisms 4 is one, at this time, the left and right ends of the support unit 5 of the first support rolling mechanism 3 or the support unit 5 of the second support rolling mechanism 4 are respectively disposed on the left and right sides of the bottom surface area of the rear side of the wagon box body 1, that is, at this time, the distance between the left and right sides of the first end of the support unit 5 is equal to the distance between the left and right sides of the wagon box body 1. Specifically, the whole of the support unit 5 may be a planar structure, and the rolling units 6 are disposed on the left and right sides of the planar structure away from the second end of the vehicle body 1, or of course, a third rolling unit 6 may be disposed in the middle of the second end of the planar structure. Or, the upper part of the supporting unit 5 is of an integral structure from left to right, the middle lower part of the supporting unit 5 is of a stick-shaped structure, for example, two supporting rods are respectively arranged on the left side and the right side of one end of the upper integral structure of the supporting unit 5, which is far away from the bottom surface of the carriage body 1, and the rolling unit 6 is arranged at the second end of each supporting rod. At this time, even one first supporting rolling mechanism 3 and one second supporting rolling mechanism 4 can better realize the support of the carriage body 1.
Further, the truck box further comprises: a locking mechanism; the locking mechanism is arranged on the front guide roller 2 and the rolling unit 6, when the locking mechanism is closed, the front guide roller 2 and the rolling unit 6 are in a rollable state, and when the locking mechanism is opened, the front guide roller 2 and the rolling unit 6 are in a non-rollable state. After the wagon box is installed, in order to fix the wagon box on the wagon bottom plate, the locking mechanisms of the front guide roller 2 and the rolling unit 6 are unlocked; when the wagon box is mounted or dismounted, the front guide roller 2 and the rolling unit 6 are required to be in a rolling state, and at the moment, the locking units of the front guide roller 2 and the rolling unit 6 are closed. After the wagon box is disassembled, in order to fix the position of the wagon box, the locking mechanisms of the front guide roller 2 and the rolling unit 6 can be unlocked. It should be noted that, of course, the wagon box body 1 may be fixed to the wagon floor by providing a wagon box lock on the wagon box.
In a possible implementation manner, the rotation of the supporting units 5 of the first supporting rolling mechanism 3 and the second supporting rolling mechanism 4 of the wagon box of the wagon can be controlled by a controller, that is, the wagon box of the wagon also comprises a control mechanism, the supporting units 5 of the first supporting rolling mechanism 3 and the second supporting rolling mechanism 4 are electrically connected with the control mechanism, and the supporting units 5 of the first supporting rolling mechanism 3 can be respectively controlled to rotate from a first preset position to a second preset position and from the second preset position to the first preset position by different keys of the control mechanism; meanwhile, the supporting unit 5 of the second supporting and rolling mechanism 4 can be controlled to rotate from the first preset position to the second preset position and from the second preset position to the first preset position through other keys. That is, the first supporting and rolling mechanism 3 and the second supporting and rolling mechanism 4 can be controlled by the control mechanism, respectively. The first supporting rolling mechanism 3 and the second supporting rolling mechanism 4 can be more conveniently controlled by an electric control method, so that the wagon box can be further used as an unmanned wagon box, and the wagon box has important significance in the field of unmanned driving or automatic driving.
