As shown in fig. 1 to 8, the present invention provides a battery transport package which mainly includes a carrier 131, a first tray deck 130 (one schematic structure of the tray deck), at least one elastic member 133, and at least one pair of self-centering assemblies 134.

As shown in fig. 1, 2, 5 to 7, the carrier 131 is configured substantially as a rectangular frame structure formed by connecting cross members and longitudinal members, and is used for placing the battery 10. The carriage 131 is disposed laterally above the first tray stack 130. The elastic members 133 are connected to the carriage 131 and the first tray layer 130, respectively, and are capable of applying an elastic force to the carriage 131 away from the first tray layer 130, so that the carriage 131 is movable in the vertical direction with respect to the first tray layer 130. In the present embodiment, the elastic member 133 can apply an upward elastic force to the carrier 131, and the upward elastic force applied to the carrier 131 by the elastic member 133 is greater than the weight of the carrier 131, so that the carrier 131 is in a floating state without contact with the first tray layer 130 when empty.

Fig. 2, 3, 5 to 7 schematically show four elastic members 133, and the four elastic members 133 are symmetrically disposed with respect to a center line of the carrier 131 in the longitudinal direction and symmetrically disposed with respect to a center line of the carrier 131 in the width direction, so that the load applied to the carrier 131 is uniform. It is understood that the number of the elastic members 133 is not limited to the present embodiment, and the number of the elastic members 133 may be two, six, eight, or any suitable number as needed.

As shown in fig. 5, when the carrier 131 is unloaded, the upward elastic force applied to the carrier 131 by the elastic member 133 is greater than the gravity of the carrier 131, so that the carrier 131 is not in contact with the first tray layer 130 in a floating state. As shown in fig. 6, when the loading frame 131 loads the battery 10, the elastic member 133 is compressed under the gravity of the battery 10 and the gravity of the loading frame 131, so that the loading frame 131 moves downward a distance and even sits above the first tray layer 130, and the loading frame 131 is in a loading state.

As shown in fig. 2, 3, 5 to 7, the at least one pair of automatic centering assemblies 134 are symmetrically disposed at both sides of the carrier 131 and are used to abut the battery 10. The self-centering assembly 134 is fixedly coupled to the carrier 131 and movably coupled to the first tray stack 130. In this embodiment, the at least one pair of self-centering assemblies 134 is movable relative to the first tray layer 130 to center the battery 10 on the carriage 131 as the carriage 131 moves in the vertical direction. Therefore, after the batteries 10 are placed on the carrier 131, under the action of the gravity of the carrier and the batteries 10, the elastic members 133 are compressed, so that the carrier 131 moves downwards to cling to the first tray layer 130, the downward movement of the carrier 131 enables the automatic centering assembly 134 to move relative to the first tray layer 130, so that the batteries 10 are automatically centered and limited on the carrier 131, so as to prevent the batteries 10 from moving left and right, and the battery transportation package is simple in structure, high in safety and convenient to operate.

The battery transport package of the present embodiment may include a plurality of pairs of automatic centering assemblies 134, and the pairs of automatic centering assemblies 134 are symmetrically disposed at both sides of the carrier 131. Four pairs of self-centering assemblies 134 (i.e., eight self-centering assemblies 134) are schematically illustrated in fig. 2, 3, 5 to 7, four self-centering assemblies 134 are respectively disposed on each side of the carriage 131, and the four self-centering assemblies 134 are disposed at equal intervals. It is understood that the pairs of self-centering assemblies 134 may also be symmetrically disposed at both ends of the carrier 131, as desired.

As shown in fig. 5 to 7 and 10, the automatic centering assembly 134 mainly includes a rotating member 135, a limiting member 136, and a weight member 137.

The rotating member 135 is rotatably connected to the carrier 131 about a first axis, the limiters 136 and the weights 137 are respectively connected to the rotating member 135, and the weights 137 abut to the first tray layer 130. In the present embodiment, the number of the rotating members 135 is two, and the stopper 136 is integrally molded with the rotating members 135 (see fig. 10). It is understood that the number of the rotating member 135 may be one, and the limiting member 136 and the rotating member 135 may be separate members, and the limiting member 136 is connected to the rotating member 135.

The stopper 136 is adapted to abut against the battery 10 to at least restrict the lateral movement of the battery 10. The weight 137 can be used to counterbalance such that the center of gravity of the self-centering assembly 134 is closer to the first tray layer 130, such that the weight 137 can always be in contact with the first tray layer 130 and facilitate rotation of the rotator 135 to unlock the restraint of the battery 10 by the restraint 136 during lifting of the carrier 131. In addition, a buffer member may be disposed on a surface of the limiting member 136 contacting the battery 10, and the buffer member may be made of silicone or rubber, so as to prevent the limiting member 136 from scratching the battery 10.

The weight 137 is rotatably connected to the rotating member 135 about a second axis parallel to the first axis, and the weight 137 horizontally moves along the first tray layer 130 as the carriage 131 moves in the vertical direction. Preferably, the weight member 137 is a structure having a circular arc surface for contacting the first tray layer 130 without damaging the first tray layer 130. In the present embodiment, the weight 137 is a roller. Furthermore, it is also possible to replace the weight 137 with a torsion spring, and the weight 137 is connected to the first tray layer 130, so that the stopper 136 is in an unlocked state without restricting the lateral movement of the battery 10 when the carrier 131 is in a floating state.

With continued reference to fig. 5-7 and 10, the self-centering assembly 134 further includes a connector 138, a first shaft 139 and a second shaft 141, the first shaft 139 being parallel to the second shaft 141. Specifically, the first axis is a central axis of the first shaft 139, and the second axis is a central axis of the second shaft 141. As shown in fig. 5, the link member 138 is connected to the carrier 131, the first shaft 139 rotatably connects the rotating member 135 to the link member 138, and the second shaft 141 rotatably connects the weight member 137 to the rotating member 135.

More specifically, the rotary member 135 is configured as an (approximately) L-shaped structure, and the stopper member 136 and the weight member 137 are respectively provided at both ends of the rotary member 135. Preferably, the weight 137 is provided with two limiting walls 142, the two limiting walls 142 are arranged in parallel and are used for cooperating with the first tray layer 130, so that the weight 137 moves horizontally along the first tray layer 130. In the present embodiment, the limiting walls 142 are engaged with the cross member 146 of the first tray deck 130, and as shown in fig. 5 and 6, the two limiting walls 142 are disposed at both sides of the cross member 146 of the first tray deck 130 so that the weight member 137 can be horizontally moved only along the first tray deck 130 to limit the front-rear play of the battery 10.

The battery transport package further comprises at least two locking hooks 143, the at least two locking hooks 143 being arranged at least on both sides of the carrier 131. Preferably, the at least two locking hooks 143 are symmetrically disposed at both sides of the carrier 131. The at least two latch hooks 143 may also be symmetrically disposed at both ends of the carrier 131. As shown in fig. 10, the latch hook 143 has a kidney-shaped hole 147, and the latch hook 143 is rotatably disposed on the first shaft 139 via the kidney-shaped hole 147 and is configured to cooperate with a cooperating structure of the battery 10 to fix the battery 10 on the carrier 131. The number of the latch hooks 143 may be determined according to the fitting structure of the battery 10.

In the present embodiment, the lock hook 143 is switchable between a release position and a lock position cooperating with the cooperating structure, the waist-shaped hole 147 extending in a vertical direction when the lock hook 143 is in the release position such that the lock hook 143 is movable in the vertical direction with respect to the first shaft 139, and the waist-shaped hole 147 extending in a direction at an angle to the vertical direction when the lock hook 143 is in the lock position to restrict the lock hook 143 from moving in the vertical direction with respect to the first shaft 139. In fig. 5 and 6, four locking hooks 143 are schematically shown, the four locking hooks 143 being symmetrically arranged on both sides of the carrier 131. Further, the latch hook 143 may also have an eccentric portion such that its center is biased toward the battery 10 side when the latch hook 143 locks the battery 10.

Specifically, the first shaft 139 extends through the waist-shaped hole 147, and when the battery 10 is placed on the carriage 131, the first shaft 139 is movable relative to the waist-shaped hole 147 along the length direction of the waist-shaped hole 147, so that the latch hook 143 can rotate relative to the first shaft 139 during movement of the self-centering assembly 134 relative to the first tray layer 130. The stroke of the elastic member 133 may be determined according to the centering distance of the locking hook 143, and in the present embodiment, the stroke of the elastic member 133 is preferably 30 ± 1mm.

The battery transport package may further include a positioning member provided to the carrier 131 and having a slope guide surface to positionally guide the front and rear positions of the battery 10. The positioning member may be made of a flexible material such as rubber or silicone, or may be made of a stainless steel plate material.

As shown in fig. 1 and 2, the battery shipping package includes at least two first tray decks 130. The at least two first tray layers 130 are stacked in the height direction of the battery shipping package, and the first tray layers 130 may be made of metal or a non-metal material such as resin. Only two first tray decks 130 are schematically shown in fig. 1 and 2.

As shown in fig. 3-9, the first tray deck 130 basically includes a frame 132 and a column assembly 160. The frame 132 is constructed substantially as a rectangular parallelepiped structure formed by connecting cross members and longitudinal members. The pillar assemblies 160 are rotatably disposed at four corner positions of the frame 132 about the horizontal direction, that is, each of the first tray decks 130 includes four pillar assemblies 160. Specifically, mast assembly 160 is rotatably connected to frame 132 via a rotation shaft (not shown) that is perpendicular to mast assembly 160. The post assembly 160 includes two support posts that are perpendicular to each other and have different lengths, as will be described in more detail below.

In the present embodiment, the battery transport package is switchable between a first state (see fig. 1) in which the first tray deck 130 is located at the first position and a second state (see fig. 2) in which the first tray deck 130 is located at the second position. When the battery shipping package is in the first state, the column assemblies 160 between adjacent first tray decks 130 are inserted into each other in the first position. When the battery shipping package is in the second state, the column assemblies 160 between two adjacent first pallet layers 130 are inserted into each other in the second position. The second position of the post assembly 160 is a position in which the post assembly 160 is rotated 90 from the first position. Therefore, the battery transportation package can be recycled, the space utilization rate is improved, and the occupied volume of the battery transportation package can be smaller when the battery transportation package returns or is stored in an empty box, so that the battery transportation package is convenient to transport or store.

As shown in fig. 1 to 4 and 7 to 9, the column assembly 160 includes a long support column 161 and a short support column 162, the long support column 161 being perpendicular to the short support column 162 and being longer than the short support column 162. In this embodiment, the long support columns 161 and the short support columns 162 are circular tubes, and the long support columns 161 and the short support columns 162 may be square tubes or other tubes of any shape as required. When the battery shipping package is in the first state, the long support columns 161 of the column assemblies 160 between adjacent first tray layers 130 are inserted into one another (see fig. 1) for use in shipping the battery 10. When the battery shipping package is in the second state, the short support posts 162 of the column assemblies 160 between adjacent first pallet layers 130 are inserted into one another (see fig. 2) for use when returning empty boxes. It will be appreciated that other batteries 10 or other materials having a shorter height may also be transported when the battery shipping package is in the second state.

As shown in fig. 4 and 7-9, the long support columns 161 have a first male head end 163 and a first female head end 164 adapted to the structure of the first male head end 163, and the short support columns 162 each have a second male head end 165 and a second female head end 166 adapted to the structure of the second male head end 165.

When the battery shipping package is in the second state, the second male ends 165 and the second female ends 166 of the short support posts 162 of the column assemblies 160 between adjacent two first tray decks 130 are plugged into each other (see fig. 1).

As shown in fig. 4, the first male tip 163 is provided with a first guide surface 167 extending along the circumferential direction and inclined so as to insert the first male tip 163 and the first female tip 164 of the long support column 161 of the pillar assembly 160 between two adjacent first tray layers 130. Further, the second male tip 165 is provided with a second guide surface (not shown) extending in the circumferential direction and inclined so as to facilitate the insertion of the second male tip 165 and the second female tip 166 of the short support column 162 of the pillar assembly 160 between two adjacent first pallet layers 130.

As shown in fig. 2, 3, and 5 to 7, in the present embodiment, the elastic member 133 is a spring post. The elastic member 133 includes a fixed portion 144, a movable portion 145, and a force accumulating portion (not shown), the fixed portion 144 is disposed below the movable portion 145 and connected to the frame 132 of the first tray layer 130, the movable portion 145 is fixedly connected to the carrier 131, and the force accumulating portion is respectively connected to the fixed portion 144 and the movable portion 145 and capable of applying an elastic force away from the fixed portion 144 (i.e., applying an upward elastic force) to the movable portion 145, so that the movable portion 145 can bring the carrier 131 to move in a vertical direction with respect to the fixed portion 144. The elastic member 133 may also be a gas support rod or a link assembly.

In addition, the carrier 131 may further include a guide (not shown) to guide the movable part 145 to move in the vertical direction with respect to the fixed part 144, so that the vertical movement of the carrier 131 is smooth.

In the present embodiment, the second tray layer 110 further includes tray columns 112 provided at four corner positions of the main body frame 111. The second pallet layer 110 may also be provided with fork pockets 114 for the forklift to fork, for example, the fork pockets 114 may be provided around the main body frame 111. The at least two first tray decks 130 are stacked above the second tray deck 110 in the height direction of the battery shipping package. When the battery transport package is in the first state, the long support columns 161 of the column assemblies 160 of the first tray layer 130 positioned at the lowermost layer are inserted into the tray columns 112, and when the battery transport package is in the second state, the short support columns 162 of the column assemblies 160 of the first tray layer 130 positioned at the lowermost layer are inserted into the tray columns 112.

Preferably, the outer surface profile of the long support columns 161 and the short support columns 162 do not exceed the outer surface profile of the second pallet layer 110. That is, the long support columns 161 and the short support columns 162 do not exceed the length and width dimensions of the second tray stack 110 whether the first tray stack 130 is in the first position or the second position, and thus do not additionally increase the length and width dimensions of the battery shipping package. Therefore, in the present embodiment, the first male end 163 of the long support column 161 and the second female end 166 of the short support column 162 are as short as possible while ensuring their functions. For example, the limit shape of the stud assembly 160 may be configured as a T-shape, e.g., the second female end 166 of the short support post 162 does not exceed the outer surface of the long support post 161.

It is further preferred that the long support post 161 be height adjustable to facilitate transportation of batteries 10 having different heights. For example, long support column 161 can be formed by two different cylinders with different connecting positions between the two cylinders by a pin, so that long support column 161 has different lengths. In addition, the height of the long supporting column 161 can be adjusted in other ways, and the height of the long supporting column 161 is a common structure in the art and will not be described in detail.

As shown in fig. 12, in the present embodiment, the tray column 112 is provided with an insertion part 113, the insertion part 113 is configured to be convex, the insertion part 113 is inserted with a first female head end 164 of a long support column 161 of the column assembly 160 of the first tray deck 130 positioned thereabove when the battery transport package is in the first state, and the insertion part 113 is inserted with a second female head end 166 of a short support column 162 of the column assembly 160 of the first tray deck 130 positioned thereabove when the battery transport package is in the second state.

In one embodiment, not shown, the mating portion 113 may also be configured as a recess, the mating portion 113 mating with the first male end 163 of the long support column 161 of the column assembly 160 of the first tray deck 130 positioned above the mating portion 113 when the battery shipping package is in the first state, and the mating portion 113 mating with the second male end 165 of the short support column 162 of the column assembly 160 of the first tray deck 130 positioned above the mating portion 113 when the battery shipping package is in the second state

As shown in fig. 1-4 and 7-7, the first tray layer 130 further includes an attachment mechanism 170, the attachment mechanism 170 being disposed at the first female end 164 of the long support column 161. The connecting mechanism 170 connects the long support column 161 of the column assembly 160 of the first tray deck 130 with the tray column 112 of the second tray deck 110 positioned therebelow or the long support column 161 of the column assembly 160 of the first tray deck 130 positioned therebelow when the battery shipping package is in the first state. Therefore, through the arrangement of the connecting mechanism 170, the stacking among the multiple layers of the first tray layers 130 and the connection between the first tray layers 130 and the second tray layers 110 can be realized, and the structure of the battery transportation package is stable so as to adapt to the extrusion and the jolt brought by various complex road surfaces in the transportation process, and the safety performance is good.

In this embodiment, the connection mechanism 170 is a clamping mechanism, which may be, for example, a quick release tube clamp disposed outside the first female end 164 of the long support post 161, and the battery transport package can be installed and removed without the need for additional tools. Therefore, the battery transportation package according to the embodiment has small limitation on application environment, and is suitable for being used under complex working conditions.

As shown in fig. 3, 4, 8 and 9, the first tray layer 130 further includes a cover plate assembly 150, the cover plate assembly 150 being disposed at an outer periphery of the frame 132 and serving to shield an outer periphery of the cells 10 located below the first tray layer 130. The hood plate assembly 150 includes two end folding flaps 151, two side folding flaps 152, and four connecting plates 153. The end folding flaps 151, the side folding flaps 152, and the connection plates 153 may be made of corrosion-resistant materials such as aluminum, stainless steel, painted steel, and PVC.

The end folding flaps 151 are rotatably provided at both ends of the frame 132 around the width direction of the frame 132, and the side folding flaps 152 are rotatably provided at both sides of the frame 132 around the length direction of the frame 132. The end folding flaps 151 and the side folding flaps 152 are shown in an unfolded state in fig. 1, 3, 4, 7, and 11, which are disposed in a substantially vertical direction to cover the periphery of the frame 132. The end folding flaps 151 and the side folding flaps 152 are shown in fig. 2, 7 and 8 in a folded state, which is arranged below the frame 132 extending substantially in the horizontal direction, i.e. turned 90 ° inwards overall, so that the height of the first tray layer 130 in the second position is reduced, i.e. the occupied volume is reduced.

Specifically, the upper end of the end folding flap 151 is hinged to the frame 132, and at least one of the long support column 161 and the short support column 162 is fixedly connected to the end folding flap 151, and the side folding flap 152 is hinged to the frame 132. In the present embodiment, both ends of the end-face folding flap 151 are connected to long support posts 161 of one post assembly 160, respectively (see fig. 9). Further, a rotation shaft as described above may also be provided on the end folding flap 151 so that the pillar assembly 160 rotates about the rotation shaft together with the end folding flap 151.

The side folding flaps 152 are hinged to the frame 132 by means of torsion springs, and in the free state, the side folding flaps 152 are unfolded outward and are located inside the pillar assemblies 160, and when the side folding flaps 152 are in the folded state, the side folding flaps 152 are located between the end folding flaps 151 and the frame 132.

The attachment panels 153 are disposed about the frame 132 and at least partially over the end folding flaps 151 and the side folding flaps 152. Specifically, the upper ends of the connecting plates 153 extend upward beyond the upper sides of the end-face folding flaps 151 and the side-face folding flaps 152, and the lower ends of the connecting plates 153 are located inside the end-face folding flaps 151 and the side-face folding flaps 152, so that a corrugated structure is formed between the end-face folding flaps 151 and the side-face folding flaps 152 of the first tray layer 130 located on the upper layer and the connecting plates 153 of the first tray layer 130 located on the lower layer (see fig. 7). Therefore, timely dredging of outside rainwater is facilitated, and the possibility that the battery 10 is wetted by rainwater is reduced. In addition, the end-face folding baffle 151, the side-face folding baffle 152 and the connecting plate 153 made of metal are not only wear-resistant but also extrusion-resistant, so that the internal battery 10 is less susceptible to rainwater and has good transportation safety performance.

In the present embodiment, the elastic members 133 are compressed by the weight of the loading frame 131 and the battery 10, so that the loading frame 131 which is originally suspended can move downwards and cling to the frame 132 of the first tray layer 130, and when the loading frame 131 moves downwards, the weight members 137 are driven to slide outwards along the cross beams 146 of the first tray layer 130, and the stoppers 136 are driven to rotate inwards and fasten the battery 10. Because the elastic member 133 can only move up and down, the bearing frame 131 and the first tray layer 130 are always kept in a parallel state, and the symmetrically arranged locking hooks 143 enable the bearing frame 131 to be in a completely symmetrical state relative to the central plane of the first tray layer 130, so that the battery 10 can be automatically centered and placed in the process that the automatic centering assembly 134 pushes the battery 10, and unbalanced loading is prevented.

After the battery 10 is placed, the latch hook 143 is manually placed into a mating structure of the battery 10, such as a lifting hole, and the end of the latch hook 143 protruding into the lifting hole is configured to have a hook shape that achieves a self-locking condition, preventing the battery 10 from bouncing and separating from the frame 132 of the first tray layer 130 during transportation. When the latch hook 143 is not removed, the lifting hole of the battery 10 is occupied by the latch hook 143, and the lifting appliance cannot be normally inserted, so that the battery 10 cannot be lifted, and the dangerous situation that the battery 10 is lifted without being separated from the outer package is avoided.
