In the present embodiment, the caster units 121 of the moving mechanism 12 are provided on the bottom 111 of the container body and function to support the container body 11 of the container 1 mounted on the vehicle after the container body 11 is detached from the vehicle body 2, and to move the container body 11 by the caster units 121 after the container body 11 is detached from the vehicle body 2, thereby allowing the container body to move by itself. The caster assemblies 121 are required to have a use position and a storage position, and mainly when the box body 11 is placed on the vehicle body 2 or separated from the vehicle body 2, the caster assemblies 121 in the box body 11 can be changed correspondingly so as to facilitate storage or movement of the box body 11. Specifically, when the caster assemblies 121 are in the storage position, the caster assemblies 121 are retracted to the case bottom 111, so that the case 11 can be stably and reliably placed on the vehicle body 2, and at the same time, the space occupied by the case 11 on the vehicle body 2 can be reduced. When the caster wheel assembly 121 is in the use position, the caster wheel assembly 121 is extended outwards from the bottom 111 of the box body, and the box body 11 can be supported and moved on the ground, so that the self-walking is realized.

The locking assembly 13 is mainly used for unlocking and locking the caster assemblies 121 in the use position, so as to prevent the caster assemblies 121 from being folded to affect the movement of the box body 11 when the box body 11 moves in the unfolded state of the caster assemblies 121. Meanwhile, when the box body 11 is changed from the separated position to the assembled position by setting the locking of the locking assembly 13 to the caster assembly 121 to be unlockable, the caster assembly 121 is changed from the use position to the storage position by unlocking the caster assembly 121.

second caster assemblies

1211 and 1212 are gradually brought into the use position in sequence as the case 11 moves from the assembly position toward the disassembly position.

It should be noted that, in the present embodiment, the first caster assembly 1211 and the second caster assembly 1212 are spaced apart from each other in the inward and outward directions of the vehicle body 2, and the purpose of the present embodiment is mainly to enable the caster assemblies 121 to be uniformly arranged on the bottom portion 111 of the box body, so that the weight of the cargo in the box body 11 and the box body 11 can be uniformly distributed on the two caster assemblies 121, thereby achieving convenient use and improving the service life of the caster assemblies 121. Here, the first caster assembly 1211 and the second caster assembly 1212 movably support the casing 11 include two meanings, that is, the two caster assemblies 121 can support the casing 11 on one hand, and the two caster assemblies 121 can also move the casing 11 on the other hand.

In addition, since the side of the box body 11 close to the lateral side door 211 is separated from the vehicle body 2 first during the separation of the box body 11 from the vehicle body 2, the caster assembly 121, i.e., the first caster assembly 1211, disposed on the side of the box body 11 needs to be moved into the use position first, so as to support the portion of the box body 11 separated from the vehicle body 2 first, maintain the balance of the box body 11 during the separation, and prevent the box body 11 from rolling over. Then, as the box body 11 continues to move in the direction of the side door 211, the remaining part of the box body 11 is gradually separated from the vehicle body 2, at this time, the second caster assembly 1212 is gradually opened and transits to the use position, and finally, the whole box body 11 is completely removed from the vehicle body 2. In this process, locking and unlocking of the first caster assembly 1211 by the locking assembly 13 is required, and details about this part will be described in detail in other parts.

In this embodiment, one end of the torsion spring 11131 is fixed to the case bottom 111, and the other end is fixed to the second caster bracket 12121, so that the first caster assembly 1211 first enters the use position and the second caster assembly 1212 gradually enters the use position when the case 11 is separated from the vehicle body 2. And in the process that second truckle subassembly 1212 gradually enters into the position of use, because box 11 separates with automobile body 2 gradually, therefore second truckle subassembly 1212 begins to fall gradually from the one end that is close to second truckle 12122 under self gravity effect, this in-process, for avoiding self gravity not enough to arouse that the condition that second truckle subassembly 1212 is difficult to enter into the position of use fast takes place, first elastic component 1113 has been add between bottom of the box portion 111 and second truckle support 12121, also torsional spring 11131, under the assistance of this torsional spring 11131's tensile effect, second truckle subassembly 1212 can enter into the position of use fast smoothly.

Referring to fig. 1 to 4 and 8, as a possible implementation manner, the locking assembly 13 includes a second slider 131 movably disposed on the box bottom 111 in the inward and outward directions, and a first locking member 132 and a second locking member 133 disposed on the second slider 131, the first locking member 132 is used for locking the first caster assembly 1211 firstly entering the use position by moving along the second slider 131 relative to the box bottom 111, and the second locking member 133 is used for locking the second caster assembly 1212 subsequently entering the use position while the first locking member 132 keeps locking the first caster assembly 1211.

It should be noted that, in the present embodiment, the locking assembly 13 switches between locking and unlocking the first caster assembly 1211 and the second caster assembly 1212 by moving the second slider 131 relative to the case bottom 111. Specifically, the first locking member 132 is used to lock the first caster assembly 1211 when in the advanced use position, and the second locking member 133 is used to lock the second caster assembly 1212 when in the rearward use position. Here, the condition that the first locking member 132 needs to lock the first caster assembly 1211 is that the first locking member 132 needs to always maintain the locking of the first caster assembly 1211 during the period from the first caster assembly 1211 being in the use position to the second caster assembly 1212 being brought into the use position, so that the first caster assembly 1211 can always be reliably maintained in the use position during the period.

With reference to figures 6 to 8 of the drawings, as shown in fig. 16 and fig. 18 to 22, as a possible implementation manner, the locking assembly 13 includes a second slider 131 movably disposed on the box bottom 111 in the inward and outward directions, and a first locking member 132 and a second locking member 133 disposed at an interval in the extending direction of the second slider 131, a first locking post 12113 collinear with the rotation axis thereof is disposed on the first caster bracket 12111, a second locking post 12123 collinear with the rotation axis thereof is disposed on the second caster bracket 12121, an outer peripheral surface of the first locking post 12113 has at least one first locking surface 12113a forming a plane, an outer peripheral surface of the second locking post 12123 has at least one second locking surface 12123a forming a plane, a third locking surface 132a for cooperating with the first locking surface 12113a is formed on the first locking member 132, and a fourth locking surface 133a cooperating with the second locking surface 12123a is formed on the second locking member 133.

In the use position, the first locking surface 12113a is rotated to be parallel to the third locking surface 132a and the second locking surface 12123a is rotated to be parallel to the fourth locking surface 133a, and by the movement of the second slider 131 relative to the case 11, the first locking surface 12113a and the third locking surface 132a, and the second locking surface 12123a and the fourth locking surface 133a can be brought into contact or separated in the inward and outward directions, respectively, to switch between the locked or unlocked states.

In this embodiment, the locking assembly 13 locks the first caster assembly 1211 in the use position by the first locking member 132, and the locking assembly 13 locks the second caster assembly 1212 in the use position by the second locking member 133. The locking assembly 13 locks the first caster assembly 1211 and the second caster assembly 1212 by contact between surfaces. Specifically, when the first caster assembly 1211 enters the use position, the first caster bracket 12111 rotates the first locking post 12113 collinear with the rotation axis thereof from the horizontal state to the vertical state, at this time, the first locking surface 12113a on the first locking post 12113 also rotates 90 ° to the extent that when the first caster assembly 1211 enters the use position, the first locking surface 12113a on the first locking post 12113 makes surface-to-surface contact with the third locking surface 132a on the first locking member 132, and at this time, the first locking member 132 in the locking assembly 13 can achieve contact locking of the first caster assembly 1211. Here, the locking process of the second caster assembly 1212 is similar to the locking process of the first caster assembly 1211, and the locking process of the first caster assembly 1211 can be referred to, and the description of the embodiment is omitted here.

In addition, during the process that the second slider 131 moves in the inward and outward directions relative to the box 11, the second slider 131 drives the first locking member 132 and the second locking member 133 to move therewith, so that the third locking surface 132a of the first locking member 132 can make surface-to-surface contact with or separate from the first locking surface 12113a of the first locking column 12113, and simultaneously, the fourth locking surface 133a of the second locking member 133 can make surface-to-surface contact with or separate from the second locking surface 12123a of the second locking column 12123, thereby switching the locking and unlocking states of the first caster assembly 1211 and the second caster assembly 1212.

In addition, the number of the first locking surfaces 12113a that can be formed on the outer peripheral surface of the first locking column 12113 may be one or more, and the present embodiment is not limited thereto, and may be flexibly set according to actual use needs. It should be noted that the first locking surface 12113a is a flat surface, and the flat surface is arranged so that when the first caster assembly 1211 is brought into the use position, the flat surface rotates to the locking position in synchronization with the first caster assembly 1211 and comes into surface-to-surface contact with the first locking surface 12113a of the first locking member 132. The second locking surface 12123a of the second locking post 12123 is disposed in a manner similar to the first locking surface 12113a of the first locking post 12113, and the description of this embodiment is omitted here.

Referring to fig. 9, as a possible implementation, the length of the third locking surface 132a is greater than the length of the fourth locking surface 133a in the inward and outward directions, so that the third locking surface 132a still keeps contact-locking with the first locking surface 12113a when the fourth locking surface 133a unlocks the second locking surface 12123 a.

In the present embodiment, the length of the third locking surface 132a (see fig. 9, the length of the third locking surface 132a is denoted by a letter a) is made longer than the length of the fourth locking surface 133a (see fig. 9, the length of the fourth locking surface 133a is denoted by a letter b), and the purpose is mainly to make the third locking surface 132a maintain contact locking with the first locking surface 12113a when the fourth locking surface 133a unlocks the second locking surface 12123 a. Specifically, in the process that the first caster assembly 1211 is in the use position and the second caster assembly 1212 is moved from the storage position to the use position, the third locking surface 132a of the first locking member 132 needs to always maintain contact locking with the first locking surface 12113a of the first locking column 12113, so that the first caster assembly 1211 can always reliably maintain the use position until the second caster assembly 1212 is moved to the use position, at which time, not only the first locking surface 12113a is contact-locked by the third locking surface 132a, but also the second locking surface 12123a is contact-locked by the fourth locking surface 133 a.

As one possible implementation, as shown in fig. 6 to 7 and 12 to 13, the first locking cylinder 12113 is configured as a triangular prism structure i that is collinear with the rotational axis of the first caster bracket 12111, the triangular prism structure i is vertically disposed on a side of the first caster bracket 12111 adjacent to the locking assembly 13, and one circumferential side surface of the triangular prism structure i is formed as a third locking surface 132 a.

In this embodiment, the first locking column 12113 and the second locking column 12123 may have a triangular prism structure, a cubic structure, a semi-cylindrical structure, a U-arc column structure, or the like, which is not limited in this embodiment and is specifically for achieving the purpose of the present disclosure. Here, the triangular prism structure i is vertically disposed at a side of the first caster bracket 12111 close to the locking assembly 13 means that a bottom surface or a top surface of the triangular prism structure i is disposed in contact with the first caster bracket 12111, and one of three side surfaces of the outer circumference thereof is formed as a third locking surface 132a to achieve that the side surface on the triangular prism structure i locks the first caster assembly 1211 when the first caster assembly 1211 is brought into the use position. Similarly, the arrangement mode of the triangular prism structure ii on the second caster bracket 12121 and the working mode of the triangular prism structure ii are similar to the triangular prism structure i, and this embodiment is not described herein again.
