Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings, which illustrate representative embodiments of the present invention and do not limit the present invention.

As shown in fig. 1 and 2, the present invention provides an open top container 100, which can realize convenient and light opening and closing of a top cover 120 of the open top container 100.

Specifically, the open top container 100 includes a body 110 and a top cover 120. The case 110 has an opening at the top thereof, and goods can be placed in the case 110 or taken out of the case 110 through the opening. The top cover 120 is used to cover the opening (fig. 1). In this embodiment, the top cover 120 is foldable in the lateral direction. Specifically, the top cover 120 includes at least two top panels 121 that can be folded together. Two adjacent top plates 121 are pivoted to facilitate folding. In the illustrated embodiment, the directional term "transverse" refers to a direction along the length of the housing 110. The top cover 120 has a movable end 122 movable relative to the housing 110 and a fixed end 123 pivotally connected to the housing 110. As the movable end 122 gradually moves toward the fixed end 123, the top cover 120 is gradually folded (shown folded to the open position in fig. 2); the top cover 120 is gradually unfolded (shown unfolded to the closed position in fig. 1) as the movable end 122 is gradually moved away from the fixed end 123. It is understood that the moving end 122 and the fixed end 123 are the two ends of the top cover 120 farthest in the lateral direction.

To accomplish the opening and closing of the roof 120, the open top container 100 is further provided with a lateral pulling member 130, a longitudinal driving assembly 140, and a positioning member 150. The transverse pulling member 130 extends in the transverse direction and is connected to the moving end 122, so as to drive the moving end 122 to move back and forth in the transverse direction. The term "reciprocating" as used herein means that the moving end 122 moves toward the fixed end 123 (the moving direction is a first direction) and moves away from the fixed end 123 (the moving direction is a second direction) in the lateral direction. The longitudinal driving assembly 140 extends in a longitudinal direction and is connected with the transverse traction member 130 through a rotation shaft 160 (see fig. 5). The positioning member 150 and the rotation shaft 160 are both disposed at the top of the case 110 and are both rotatable with respect to the case 110. The positioning member 150 is connected to the lateral traction member 130 (see fig. 3), and the lateral traction member 130 is wound around the positioning member 150. The transverse traction member 130 is movable between the positioning member 150 and the rotation shaft 160.

In the illustrated embodiment, the top cover 120 includes two top covers 120 foldable in the lateral direction. Each top cover 120 is correspondingly provided with a transverse traction member 130, a longitudinal transmission assembly 140 and a positioning member 150. In other words, the lateral traction members 130, the longitudinal transmission members 140, and the positioning members 150 are arranged in groups and correspond one-to-one to the top covers 120. Specifically, the positioning member 150 is disposed at a middle portion of the case 110 in the lateral direction. The fixed end 123 of the top cover 120 is disposed at an end of the case 110. A longitudinal drive assembly 140 is also provided at the end of the housing 110. The two sets of transverse traction elements 130, longitudinal drive assembly 140 and positioning elements 150 are arranged substantially symmetrically. In an embodiment not shown, more than two caps 120 may be included. Each top cover 120 is provided with a lateral pulling member 130, a longitudinal driving assembly 140, and a positioning member 150.

As shown in fig. 1 and 3, the positioning member 150 is disposed to correspond to the position of the moving end 122 of the top cover 120 in the unfolded state. In this embodiment, the acting force of the positioning member 150, which transmits the rotation shaft 160 to the transverse pulling member 130, extends substantially in the second direction, so that the transverse pulling member 130 can drive the moving end 122 to move in the second direction. In the illustrated embodiment, the positioning member 150 is farther from the fixed end 123 of the top cover 120 relative to the moving end 122 of the top cover 120 in the deployed state. However, in an embodiment not shown, the positioning member 150 may be positioned slightly close to the fixed end 123 of the top cover 120 with respect to the moving end 122 of the top cover 120 in the unfolded state, and in this embodiment, the self weight of the top cover 120 may cause the top cover 120 to reach the closed position when the top cover 120 is to be unfolded to the closed position.

Specifically, the transverse pulling member 130 is wound around the positioning member 150 and the rotating shaft 160. The upper and lower portions of the transverse traction elements 130 are substantially parallel. The transverse traction element 130 includes a traction end 131 and an interface end 132 opposite the traction end 131. As shown in fig. 3 and 4, the pulling end 131 is wound around the positioning member 150 from below the positioning member 150, and then connected to the moving end 122 located above the pulling end 131. Specifically, the hinge 124 protruding downward from the top cover 120 is provided at the drawing end 131, and the drawing end 131 is mounted to the hinge 124. As shown in fig. 5, the connecting end 132 of the transverse pulling member 130 is wound around the rotating shaft 160, and the transverse pulling member 130 moves together with the rotating shaft 160. The rotating shaft 160 may further be provided with a limiting groove 161, and the transverse traction member 130 is limited in the limiting groove 161, so as to avoid the position deviation of the transverse traction member 130 during the moving process. The transverse traction elements 130 in the illustrated embodiment are cords. Of course, the transverse traction members 130 can be other suitable transmission members if needed and/or desired.

The top of the case 110 is also provided with a top side beam 111. A slide rail beam 112 extending in the lateral direction is provided above the roof side beam 111. The sliding rail beam 112 is provided with a sliding rail 113 extending in the transverse direction. The top cover 120 has a pulley 114 movably connected with the slide rail 113. Referring to fig. 4, the hinge 124 at the pulling end 131 is provided with a pulley 114, the pulley 114 being able to move back and forth on the sliding rail 113. Alternatively, in an embodiment in which the top plate 121 forming the top cover 120 includes at least four (typically an even number) pieces pivotally connected to each other, two adjacent top plates 121 have a first connecting portion 125 and a second connecting portion 126. During the folding of the top cover 120, the first and

second coupling portions

125 and 126 move in opposite directions, the first coupling portion 125 does not substantially detach from the top of the container body 110, and the second coupling portion 126 detaches from the top of the container. The first connecting portion 125 may be provided with another hinge 124, and the hinge 124 of the first connecting portion 125 may also be provided with the pulley 114. The pulley 114 can reciprocate on the slide rail 113.

The positioning member 150 is provided on the top side member 111. Specifically, the positioning member 150 includes a positioning member base 151 provided on the top side member 111 and a positioning member rotating shaft 152 provided on the positioning member base 151. Two opposite positioner bases 151 extend upward and are spaced apart in the width direction of the case 110, and both ends of the positioner rotating shaft 152 are mounted to the two positioner bases 151 and are rotatable with respect to the positioner bases 151. During movement of the lateral traction element 130, the positioner pivot shaft 152 rotates relative to the positioner base 151.

As shown in fig. 5 to 7, the longitudinal driving assembly 140 includes a driven wheel 141 disposed on the rotating shaft 160, and a driving wheel 142 located below the driven wheel 141. The driving wheel 142 is connected to the driven wheel 141 by a vertically extending transmission member 143. The driving wheel 142 is disposed on the case 110 and is rotatable with respect to the case 110. In the illustrated embodiment, the driving wheel 142 can also be provided with a handle 144, and the operator can rotate the driving wheel 142 relative to the housing 110 by rotating the handle 144. In this embodiment, the driver 142 is positioned at a height that facilitates manual manipulation of the handle 144 by an operator. Alternatively, the driving wheel 142 and the driven wheel 141 may be gears, and the transmission member 143 may be a chain. Alternatively, the driving pulley 142 and the driven pulley 141 may be pulleys, and the transmission member 143 may be a belt.

Specifically, as shown in fig. 6, the housing 110 is provided with mounting parts 145 opposite to each other extending outward. The drive wheel 142 is connected with the drive wheel base 146 through a drive wheel rotation shaft. The fasteners vertically pass through the mounting part 145 above the driving wheel 142, the driving wheel base 146, and the mounting part 145 below the driving wheel 142 in this order, and in this embodiment, the driving wheel 142 can be mounted to the outside of the case 110.

In order to prevent the driving wheel 142 from rotating due to the influence of external factors, a stopper 147 for limiting the rotation of the driving wheel 142 is further provided at the driving wheel 142. Thus, when the top cover 120 is in the folded state (i.e., the top cover 120 is folded to the open position), the transverse traction member 130 always pulls the movable end 122 in the first direction due to the stop of the rotation of the driving wheel 142, thereby preventing the folded state of the top cover 120 from being changed. Also, when the top cover 120 is in the unfolded state (i.e., the top cover 120 is unfolded to the closed position), the transverse traction member 130 always pulls the moving end 122 in the second direction due to the stop of the rotation of the driving wheel 142, thereby preventing the unfolded state of the top cover 120 from being changed.

In the illustrated embodiment, the stopper 147 is a stopper rod provided in the mounting hole 148 of the drive wheel base 146, and the stopper rod is detachably provided. When it is desired to limit the movement of the driver 142, the stop lever is mounted to the driver base 146 and is trapped between two teeth of the driver 142 (here, a stop position of the stop lever). When the driving wheel 142 moves, the stop rod is removed, and the driving wheel 142 can normally rotate. In an embodiment not shown, the stop 147 may be a suitable other member that prevents the drive wheel 142 from rotating.

Optionally, the open top container 100 further comprises an auxiliary open top device that supports the top cover 120 upward to partially disengage the top cover 120 from the container body 110. The auxiliary opening device can separate part of the top cover 120 from the box body 110 when the top cover 120 is just opened, so that the difficulty of directly pulling the top cover 120 from the horizontal closed position by the transverse pulling piece 130 can be reduced. Alternatively, the auxiliary roof opening devices are provided on both sides of the box body 110 in the width direction, that is, near the side plates 127 and/or the roof side rail 111.

According to an embodiment of the present invention, as shown in fig. 8 and 9, the auxiliary opening means is an elastic member 170a provided in the case 110, and the elastic member 170a provides an upward biasing force to the top cover 120 in the unfolded state. The elastic member 170a may bounce the top cover 120 upward at a certain angle when the top cover 120 is opened. In this embodiment, the top plate 121 forming the top cover 120 includes at least four pieces pivotally connected to each other. The structure of the at least four top plates 121 is described above. The elastic member 170a is disposed below the second connection portion 126. The elastic member 170a in the illustrated embodiment is a torsion spring. The torsion spring is fixed to the base on the case 110 through a pivot shaft.

It will be appreciated that since the elastic member 170a always provides the top cover 120 with an upward force, in this embodiment, it is necessary to maintain the top cover 120 in the closed position by the above-described stopper 147.

According to another embodiment of the present invention, as shown in fig. 10 to 12, the auxiliary device 170b includes a supporting member 171b disposed on the case 110 and a blocking member 172b disposed on the top cover 120, the supporting member 171b is vertically movable, the blocking member 172b laterally protrudes from the top cover 120, the supporting member 171b moves upward and supports the blocking member 172b to move upward, so that the top cover 120 can be upwardly opened to a certain angle during the movement of the supporting member 171 b. Specifically, the top plate 121 forming the top cover 120 also includes at least four pieces pivotally connected to each other, which are substantially the same in structure as the top cover 120 of the above-described embodiment. The structure of the at least four top plates 121 is described above. The stopper 172b is disposed at the second connecting portion 126, and the support 171b is disposed at the side plate 127. The support member 171b and the blocking member 172b are provided in a group. The support member 171b extends upward through the roof side rail 111 to the stopper 172 b. The side plate 127 is provided with a thrust member 173b connected to the support member 171b, and the thrust member 173b is hingedly provided on the side plate 127. When the push-aid 173b is opened outward (refer to fig. 10), the support member 171b moves upward. When the push-aid 173b is closed (refer to fig. 2), the support member 171b moves downward.

Further, the support 171b includes a vertical support 174b and a lateral lock 175b disposed at an upper end of the vertical support 174 b. The vertical support 174b is rotatable with respect to the housing 110. The blocking member 172b includes a transverse blocking member 176b connected to the top cover 120 and a vertical locking member 177b provided at an outer end of the transverse blocking member 176 b. And the vertical locks 177b extend to the outside of the vertical supports 174 b.

As shown in fig. 12, when the overcap 120 is in the closed position, the vertical support 174b is positioned above the transverse obstruction 176b, and rotation of the vertical support 174b causes the transverse lock 175b to be perpendicular to the vertical lock 177b, the vertical lock 177b being positioned outside of the transverse lock 175 b. In this embodiment, the top cover 120 may be further locked in the closed position by the positional locking between the support 171b and the stopper 172 b. The "outer side" herein refers to a side away from the center of the case 110. In the state of fig. 11, when the top cover 120 is to be opened, the vertical support 174b is rotated such that the transverse locker 175b is parallel to the transverse blocking member 176b, the vertical support 174b is moved downward such that the transverse locker 175b is positioned below the transverse blocking member 176b, and then the vertical support 174b is rotated such that the transverse locker 175b is perpendicular to the transverse blocking member 176 b; in this position, the vertical support 174b is moved upward, and the transverse lock 175b supports the transverse stopper 176b upward to move upward, thereby moving the top cover 120 upward by a certain angle (refer to fig. 11).

The open top container 100 of the present invention can be provided with the auxiliary open top device in the above two embodiments.

Alternatively, as shown in the illustrated embodiment, in an embodiment in which the top plate 121 forming the top cover 120 includes at least four pieces pivotally connected to each other, the first connection portion 125 may be provided with a hinge 124, and the hinge 124 may be provided with the pulley 114 thereon. The pulley 114 can reciprocate on the slide rail 113.
