[0081] First embodiment

[0082] See also Figures 1 to 8, the first embodiment of the present application provides a battery packaging device. The battery packaging device can be used to load goods such as batteries 170. The battery 170 can be a large vehicle battery. A battery packaging device can be used to load one battery 170. The battery packaging device may include a box assembly 100 and a limit assembly. The box assembly 100 includes a box 110 and a top cover. The box 110 includes a box space 1101. The box space 1101 is at least suitable for placing the battery 170 to be transported, and can also accommodate other goods. The top of the box 110 is provided with a top opening 119 connected to the box space 1101. The top cover is provided on the top of the box 110 to close the top opening 119. The limit assembly is located in the box space 1101. And the limit assembly is connected to the end of the first direction D1 or the second direction D2 of the box 110 by rotating around the rotation axis AX between the working position and the folded position. The first direction D1 is the length direction of the box body 110 , and correspondingly, the second direction D2 is the width direction of the box body 110 .

[0083] The first direction D1 and the second direction D2 of the box body 110 are two different horizontal directions of the box body 110. The rotation axis AX is perpendicular to the height direction D3 of the box body 110. The limit assembly located at the working position is suitable for abutting the battery 170 located in the box space 1101 to limit the battery 170 in the first direction D1 or the second direction D2, and to separate the battery 170 from the box body 110 in the first direction D1 or the second direction D2. Any two of the first direction D1, the second direction D2 and the height direction D3 of the box assembly 100 are perpendicular to each other. The limit assembly may include a telescopic rod 193 and a limit portion 194. One end of the telescopic rod 193 is rotatably connected to the box body 110 through a first rotating shaft 197. The telescopic rod 193 extends along an extension direction intersecting the rotation axis AX. For example, the telescopic rod 193 extends along an extension direction perpendicular to the rotation axis AX. The telescopic rod 193 is configured to be adjustable in length in the extension direction. The stopper 194 is connected to the end of the telescopic rod 193 away from the rotation axis AX. The stopper 194 is suitable for abutting against the battery 170. The rotation axis AX is specifically the first axis AX1 or the second axis AX2 to be described below.

[0084] According to the battery packaging device of the first embodiment of the present application, by setting a limit assembly in the box space 1101 of the box body 110, when the box space 1101 is used to place the battery 170, the limit assembly can limit the battery 170 in the first direction D1 or the second direction D2 to reduce or avoid collision of the battery 170 due to bumps and other reasons, thereby better protecting the battery 170 and improving the safety of the battery 170 during transportation. Furthermore, since the length of the telescopic rod 193 of the limit assembly is adjustable, the battery packaging device of the present application can adapt to the packaging and transportation requirements of batteries 170 of different sizes.

[0085] See also Figure 1 , Figure 2 , Figure 4 ,as well as Figures 6 to 8 , the battery packaging device may include at least two sets of limiting components. The at least two sets of limiting components include a first limiting component 191 and a second limiting component 192. The first limiting component 191 is connected to the end of the first direction D1 of the box body 110 by rotation around the first axis AX1 between the working position and the folded position. The first limiting component 191 located in the working position is suitable for abutting the battery 170 located in the space 1101 inside the box to limit the battery 170 in the first direction D1. The second limiting component 192 is connected to the end of the second direction D2 of the box body 110 by rotation around the second axis AX2 between the working position and the folded position. The second limiting component 192 located in the working position is suitable for abutting the battery 170 located in the space 1101 inside the box to limit the battery 170 in the second direction D2. By arranging the first limiting component 191 and the second limiting component 192, the battery 170 can be limited in the first direction D1 and the second direction D2, so as to better prevent the battery 170 from moving in the space 1101 inside the box, thereby effectively preventing the battery 170 from colliding with the box body 110 in the first direction D1 and the second direction D2, and further improving the safety of the battery 170 during transportation.

[0086] Among them, the end of the first direction D1 of the box body 110 can be understood as the end structure of the box body 110.

The box body 110 includes a bottom structure. The bottom structure is used to support cargo as a load-bearing structure of the box body 110. The bottom structure includes a bottom frame 114 and a floor. The floor is connected to the upper portion of the bottom frame 114. The bottom frame 114 may be fixedly connected to the end structure or share the bottom end beam 116 with the end structure. The bottom frame 114 may be fixedly connected to the side structure or share the bottom side beam 115 with the side structure. The box body 110 further includes a corner column 120 and a corner piece 121. The corner column 120 is connected between adjacent end structures and side structures and is fixed to the bottom structure. The corner piece 121 is fixedly connected to the end of the corner column 120. The corner pieces 121 are suitable for serving as load-bearing structures when the box assemblies 100 are stacked.

The connecting rod 195 is located at the end of the telescopic rod 193 away from the rotation axis AX. The limiting portion 194 is fixed to a side of the connecting rod 195 away from the rotation axis AX. The limiting portion 194 can be configured as a limiting plate.

[0090] See also Figures 1 to 7 ,as well as Fig. 9 and Fig.12 The battery packaging device may include a flip positioning member 127. The flip positioning member 127 is connected to one of the box body 110 and the limiting assembly. The flip positioning member 127 is adapted to be connected to the other of the box body 110 and the limiting assembly when the limiting assembly is in the working position to keep the limiting assembly in the working position.

[0091] In the illustrated example, the flip positioning member 127 is configured as a positioning plate. The positioning plate is fixed to the box 110. The positioning plate is located at the lower side of the rotation axis AX. When the limit assembly is located at the working position, the positioning plate is supported at the lower part of the limit assembly to keep the limit assembly at the working position.

The locking and unlocking member 128 in the unlocked position is disengaged from the locking portion 1951 to allow the position limiting assembly to move to the working position.

[0093] See also Figure 3 and Figure 5 Optionally, the battery packaging device may further include a first elastic member 129. The first elastic member 129 is connected between the box body 110 and the locking and unlocking member 128. The first elastic member 129 is adapted to apply an elastic force to the locking and unlocking member 128 toward the locking position.

[0094] Continue reading Figure 3 and Figure 5, optionally, the locking and unlocking member 128 can be movably mounted on the locking mounting member 105. The locking mounting member 105 is fixed to the box body 110 or is configured as a part of the box body 110. The locking mounting member 105 is used to install the locking and unlocking member 128 and the first elastic member 129. In the illustrated example, the locking and unlocking member 128 is an L-shaped locking pin. The locking mounting member 105 is a U-shaped plate. The locking pin passes through the U-shaped plate and is detachably connected to the locking portion 1951. The locking portion 1951 is a locking hole in which the locking pin can be inserted. The first elastic member 129 is a compression spring. The compression spring is located between two opposite parts of the U-shaped plate. The locking pin includes an operating portion, a limiting protrusion 1281 and an insertion portion arranged in sequence. The limiting protrusion 1281 is located at one end of the compression spring away from the operating portion, and the limiting protrusion 1281 is located between two opposite parts of the U-shaped plate. By pulling the operating portion, the insertion portion can be disengaged from the locking hole, and the compression spring is compressed at the same time. By releasing the operating portion, the insertion portion can be inserted into the locking hole, or the insertion portion can be reset to a position where it can intersect with the movement trajectory of the locking hole.

[0095] See also Figure 6 and Figure 7 Optionally, when the limit assembly is in the folded position, the limit portion 194 is located above the rotation axis AX. That is, the limit assembly rotates upward from the working position to move to the folded position. Correspondingly, the locking and unlocking member 128 is located above the rotation axis AX. This makes it easier for the user to operate to change the position of the limit assembly.

[0096] See also Figures 1 to 3 In some embodiments, the telescopic rod 193 may include a first rod body 1931, a second rod body 1932, and a stopper 196. The first rod body 1931 includes a first stopper 19311. The second rod body 1932 is movably connected to the first rod body 1931 in the extension direction so as to be able to change the length of the telescopic rod 193. The second rod body 1932 includes a second stopper 19321. At least one of the first stopper 19311 and the second stopper 19321 is provided in plurality and is arranged at intervals in the extension direction. The stopper 196 is movably connected to the first stopper 19311 and the second stopper 19321 to maintain the length of the telescopic rod 193.

[0097] Optionally, at least one of the first rod body 1931 and the second rod body 1932 is a hollow tube structure.

The second stopper 19321 is a second hole. A plurality of second holes are provided. The plurality of second holes are arranged at intervals in the extension direction. The stopper 196 is a latch. The latch is used to be inserted into the first hole and the corresponding second hole, so as to maintain the length of the telescopic rod 193. By pulling out the latch, the second rod body 1932 can be adjusted to move relative to the first rod body 1931, thereby changing the length of the telescopic rod 193.

[0098] See also Figures 9 to 12 In other embodiments, the telescopic rod 193 may include a first rod body 1931, a second rod body 1932, and a second elastic member 199. The second rod body 1932 is movably connected to the first rod body 1931 between the elongation limit position and the retraction limit position in the extension direction, so as to be able to change the length of the telescopic rod 193. When the second rod body 1932 is located at the elongation limit position and the stop assembly is located at the working position, the distance between the two relative stop portions 194 is the smallest. Correspondingly, when the second rod body 1932 is located at the retraction limit position and the stop assembly is located at the working position, the distance between the two relative stop portions 194 is the largest. The second elastic member 199 is connected to the second rod body 1932 to apply an elastic force toward the elongation limit position to the second rod body 1932. By setting the second elastic member 199, the stop portion 194 can be automatically reset and maintained at the elongation limit position when it is not acted upon by an external force or when the external force is removed. When goods such as batteries are placed between two opposite limiting portions 194 , the second elastic member 199 can provide a force that enables the two limiting portions 194 to clamp the goods.

[0099] Optionally, the second elastic member 199 may be a compression spring.

The first binding connector 101 may be a first rope ring fixed to the bottom end beam 116. The first binding connector 101 is fixed to both ends of the first direction D1 of the chassis 114. The first binding belt 102 is connected to the first binding connector 101 located at both ends of the first direction D1 to prevent the battery 170 from moving away from the chassis 114 at least in the height direction D3. The second binding connector 103 is fixed to both ends of the second direction D2 of the chassis 114. The second binding connector 103 may be a second rope ring fixed to the bottom side beam 115. The second binding belt 104 is connected to the second binding connector 103 located at both ends of the second direction D2 to prevent the battery 170 from moving away from the chassis 114 at least in the height direction D3.

[0103] See also Figures 1 to 8 ,as well as Fig. 9 and Fig.11 In addition, the chassis 114 includes a slot 123. The slot 123 may be a slot of an existing container. Thus, the chassis 114 has a high strength. The slot 123 may be adapted to a forklift so that the battery packaging device or the battery packaging device with the battery 170 may be transported by the forklift.

[0104] A method of using the battery packaging device according to the present application is: after the battery 170 is placed in the box 110, the locking and unlocking member 128 is moved to the unlocking position, the limiting assembly is rotated to the working position, and the limiting assembly is kept in the working position by flipping the positioning member 127. Then, according to the size of the battery 170, the length of the telescopic rod 193 of the first limiting assembly 191 and the second limiting assembly 192 is adjusted to prevent the battery 170 from moving in the first direction D1 and the second direction D2 of the box 110. Then, the first binding belt 102 is connected to the first binding connector 101, and the second binding belt 104 is connected to the second binding connector 103, so as to prevent the battery 170 from bumping and jumping during transportation. When the battery 170 is not transported, the limiting assembly is rotated to the folded position, and the limiting assembly is locked in the folded position with the locking and unlocking member 128, which can be used for the transportation of other goods.

[0105] Second embodiment

[0106] See also Figures 9 to 12 In the second embodiment, when the pair of first limiting components 191 or the pair of second limiting components 192 are located at the working position, the distance between the two relative limiting parts 194 decreases from top to bottom. The two relative limiting parts 194 can be understood as the two relative limiting parts in the pair of first limiting components 191, or the two relative limiting parts in the pair of second limiting components 192. When the pair of first limiting components 191 or the pair of second limiting components 192 are located at the working position, the space formed between the two relative limiting parts 194 is in the shape of a trumpet with the opening facing upward, so as to guide the goods such as batteries being loaded, so that the goods can be loaded more smoothly.

[0107] Specifically, the limiting portion 194 may include an abutting portion 1942 and a guiding portion 1943. The guiding portion 1943 has a first end and a second end opposite to each other. It can be understood that the first end and the second end are two ends of the guiding portion 1943 that are arranged oppositely along a certain direction. The second end of the guiding portion 1943 is connected to the abutting portion 1942. The angle between the line connecting the first end and the second end and the plane where the abutting portion 1942 is located is an obtuse angle. When the first limiting assembly 191 or the second limiting assembly 192 is in the working position, the guiding portion 1943 is located above the abutting portion 1942, and the first end is above the second end, so as to guide the movement of the goods when the goods such as batteries are loaded from top to bottom.

[0108] In the illustrated example, when the first limiting assembly 191 or the second limiting assembly 192 is located at the working position, in the two opposite limiting parts 194, the guide portion 1943 of one limiting part 194 extends upward and in a direction away from the other limiting part 194. The guiding portion 1943 has a guiding surface for contacting and guiding the movement of goods such as batteries. The guiding surface can be configured as an inclined surface inclined relative to the abutting portion 1942, or configured as a curved surface such as an arc surface, or configured as a surface composed of a curved surface and a plane. The surface of the abutting portion 1942 for abutting the goods can be configured as a plane or a surface close to a plane. When the first limiting assembly 191 or the second limiting assembly 192 is located at the working position, the surface of the abutting portion 1942 for abutting the goods intersects in the horizontal direction. For example, the surface of the abutting portion 1942 for abutting the goods is perpendicular to the horizontal direction.

[0109] See also Figures 9 to 12 In some examples, the stopper 194 is connected to the telescopic rod 193 by rotation around the third axis AX3. This can meet the packing requirements of larger-sized batteries and other goods. Fig.12 The first position is the initial position of the limiter. It can also be the final position or the use position of the limiter 194 after the battery is loaded.

[0110] Taking the state where the first limiting assembly 191 or the second limiting assembly 192 is in the working position as an example, if the distance between the upper edges of the pair of limiting parts 194 in the first position is smaller than the size of the goods to be packaged, a force can be applied to the guide part 1943 to flip the limiting part 194 so that the pair of limiting parts 194 rotate toward the second position, thereby increasing the distance between the upper edges of the pair of limiting parts 194 until the guide part 1943 can contact the goods when the goods fall, thereby facilitating the guidance of the goods.

[0111] Optionally, a torsion spring may be provided between the limiting portion 194 and the second rod 1932 so that the limiting portion 194 is automatically reset to the first position. After the battery 170 and other goods are loaded into the battery packaging device, the elastic force applied by the torsion spring to the limiting portion 194 is also conducive to making the abutting portion 1942 reliably abut against the surface of the goods. At this time, the limiting assembly is provided with a blocking portion. When the limiting portion 194 is located in the first position, the blocking portion abuts against the limiting portion 194 to prevent the limiting portion 194 from rotating away from the second position, thereby keeping the limiting portion 194 in the first position.

[0112] In other examples, the center of gravity or mass of the entire limiting portion 194 is located at the guide portion 1943 and at the side of the third axis AX3 away from the abutting portion 1942. As a result, in a natural state, the limiting portion 194 will remain in the second position under the action of its own weight. At this time, the second position of the limiting portion 194 is the initial position of the limiting portion. When the limiting portion 194 is in the second position, the spacing between the upper edges of the two relative limiting portions 194 is the largest, and it is also convenient to measure directly at this time. This makes it easy to match the battery packaging device with the batteries 170 and other goods to be packaged based on this maximum spacing and the batteries 170 and other goods to be packaged. In the process of loading the batteries 170 and other goods into the battery packaging device, the action of the batteries 170 and other goods on the limiting portion 194 causes the limiting portion 194 to rotate toward the first position. After the batteries 170 and other goods are loaded into the battery packaging device, the limiting portion 194 is located in the first position.

[0113] Let's take the state where the first limiting assembly 191 or the second limiting assembly 192 is in the working position for further explanation. Generally, the maximum distance (the distance between the upper edges) between the guide portions 1943 of the pair of limiting portions 194 is greater than or equal to the size of the goods such as the batteries 170 to be packaged when the second rod 1932 is in the extended limit position. Generally, the distance between the abutting portions 1942 of the pair of limiting portions 194 is greater than or equal to the size of the goods such as the batteries 170 to be packaged when the second rod 1932 is in the retracted limit position.

[0114] exist Fig.10 In the example shown, the stopper 194 may include a connecting ear 1944. The connecting ear 1944 is rotatably connected to the second rod 1932 as a second rotating shaft 198 through a connecting pin or the like. The first rod 1931 is rotatably connected to the vertical wall 111 through a connecting pin or the like as a first rotating shaft 197. It can be understood that the installation orientation or arrangement direction of the first rotating shaft 197 connected to the first stopper assembly 191 is different from the installation orientation or arrangement direction of the first rotating shaft 197 connected to the second stopper assembly 192.

[0115] The other configurations of the second embodiment are substantially the same as those of the first embodiment and will not be described in detail herein.

[0116] Third embodiment

[0117] See also Fig.13 Combined with Figures 1 to 12 The third embodiment of the present application provides a battery packaging device. The battery packaging device can package and transport batteries 170. The battery 170 can be a large vehicle battery. One battery packaging device loads and transports one battery 170. When the battery 170 is loaded by the battery packaging device, the battery 170 can be protected, and shock absorption and heat insulation can be achieved.

[0118] See also Fig.13 Combined with Figures 1 to 12 , the battery packaging device includes a box assembly 100. The box assembly 100 includes a box 110. The box 110 includes a vertical wall 111 and a bottom frame 114. The plane where the vertical wall 111 is located is perpendicular to the horizontal direction. The vertical wall 111 includes two end walls 112 and two side walls 113. The plane where the end wall 112 is located is perpendicular to the first horizontal direction (the first horizontal direction is the same as the first direction of the first embodiment). The plane where the side wall 113 is located is perpendicular to the second horizontal direction (the second horizontal direction is the same as the second direction of the first embodiment). The first horizontal direction and the second horizontal direction are perpendicular. The two end walls 112 are spaced apart along the first horizontal direction. The two side walls 113 are spaced apart along the second horizontal direction. The first end wall 112, the first side wall 113, the second end wall 112 and the second side wall 113 are connected end to end in sequence to form a circumferentially closed annular structure.

[0119] See also Fig.13 Combined with Figures 1 to 12 , the plane where the bottom frame 114 is located is perpendicular to the vertical direction. The bottom frame 114 is connected to the bottom end of the vertical wall 111. In this way, the box body 110 can be a substantially rectangular parallelepiped structure. At this time, the length direction of the box body 110 is parallel to the first horizontal direction. The width direction of the box body 110 is parallel to the second horizontal direction. The top end of the box body 110 has a top opening 119.

[0120] See also Fig.13 Combined with Figures 1 to 12 The battery 170 may also be a rectangular parallelepiped structure. When the battery 170 is disposed in the housing 110 , the length direction of the battery 170 is parallel to the length direction of the housing 110 . The width direction of the battery 170 is parallel to the width direction of the housing 110 .

[0121] It is understood that in embodiments not shown, the battery may also be of other structures, such as a cylindrical battery, etc. The box may also be of other structures, such as a cylindrical box, etc.

[0122] See also Fig.13 Combined with Figures 1 to 12 The box assembly 100 further includes a top cover 125. The top cover 125 is removably connected to the top of the box 110 so as to cover the top opening 119. Thus, by removing the top cover 125, the battery 170 can be loaded and unloaded into the box 110 through the top opening 119. When the battery 170 is disposed in the box 110, the top cover 125 covers the top opening 119 to protect the battery 170.

[0123] The battery packaging device also includes a protection unit 130. The protection unit 130 is used to be arranged in the box assembly 100. The protection unit 130 includes a protection member 140 and a flexible packaging member 150. The protection member 140 is configured in a granular shape. The protection member 140 is used to be arranged on the outside of the battery 170 to wrap the battery 170. The flexible packaging member 150 can be a cloth or a woven bag. The flexible packaging member 150 wraps the protection member 140. In this way, the protection member 140 and the flexible packaging member 150 constitute a buffer structure. The buffer structure wraps the battery 170. In this way, during the process of transporting the battery 170 by the battery packaging device, the buffer structure can slow down the movement of the battery 170, thereby reducing the vibration of the battery 170, thereby protecting the battery 170.

[0124] In this embodiment, the protective component 140 is used to be arranged on the outside of the battery 170 to wrap the battery 170, and the flexible packaging component 150 wraps the protective component 140 to form a buffer structure; in this way, the buffer structure wraps the battery 170, and in the process of transporting the battery 170 by the battery packaging device, the buffer structure can slow down the movement of the battery 170, thereby reducing the vibration of the battery 170, thereby protecting the battery 170 and reducing the possibility of battery leakage, corrosion, battery scrapping, and even fire.

[0125] Optionally, the box body 110 and the top cover 125 can be constructed as steel structures, thereby increasing the strength of the box body assembly 100.

[0126] Optionally, refer to Fig.13 Combined with Figures 1 to 12 , the box body 110 includes a bottom end beam 116 and a bottom side beam 115. The bottom end beam 116 is located at the end of the bottom frame 114 along the first horizontal direction. The length direction of the bottom end beam 116 is parallel to the second horizontal direction. The bottom side beam 115 is located at the end of the bottom frame 114 along the second horizontal direction. The length direction of the bottom side beam 115 is parallel to the first horizontal direction. The end of the bottom end beam 116 is connected to the end of the bottom side beam 115 to form a rectangular bottom frame. The bottom end of the end wall 112 is connected to the bottom end beam 116. The bottom end of the side wall 113 is connected to the bottom side beam 115. As a result, the strength of the bottom frame 114 is large.

[0127] Please continue to refer to Fig.13 Combined with Figures 1 to 12 The box body 110 further includes a top beam 118 and a top side beam 117. The top beam 118 is located at the top of the end wall 112. The length direction of the top beam 118 is parallel to the length direction of the bottom end beam 116. The top side beam 117 is located at the top of the side wall 113. The length direction of the top side beam 117 is parallel to the length direction of the bottom side beam 115. The end of the top beam 118 is connected to the end of the top side beam 117 to form a rectangular top frame. The top frame surrounds a top opening 119. As a result, the box body 110 has a high strength.

[0128] like Figure 4 and Figure 5 As shown, the box 110 also includes a reinforcing column 122. The reinforcing column 122 is connected to the inner surface of the vertical wall 111 (including the inner surface of the end wall 112 and the inner surface of the side wall 113). Specifically, the inner surface of the end wall 112 and the inner surface of the side wall 113 are both provided with a reinforcing column 122. The length direction of the reinforcing column 122 extends in the vertical direction. The bottom end of the reinforcing column 122 is connected to the bottom frame 114. The top end of the reinforcing column 122 is connected to the top frame. In this way, the strength of the box 110 can be further increased.

[0129] Alternatively, if Figure 6 and Figure 7 As shown, a corner post 120 is provided at the corner of the box body 110. The end wall 112 and the side wall 113 are connected by the corner post 120. A corner piece 121 is provided at the top and bottom of the corner post 120. In this way, the box body 110 can be stacked or fixed by the corner piece 121. The corner post 120 and the corner piece 121 can be the corner post and corner piece of the existing container, and will not be described in detail here.

[0130] Optionally, please continue to refer to Figure 1 and Figure 2 The base frame 114 also includes a slot 123 .

[0131] Alternatively, if Figure 1 and Figure 2 As shown, the bottom frame 114 further includes a bottom longitudinal beam 124. The bottom longitudinal beam 124 is located between the two bottom side beams 115. The length direction of the bottom longitudinal beam 124 is parallel to the length direction of the bottom side beam 115. Therefore, the bottom frame 114 has a large strength.

[0132] Alternatively, if Figures 1 to 13 As shown, a top cover locking structure 126 is also provided at the top of the box body 110. The top cover locking structure 126 is used to lock the top cover 125 covering the top opening 119. The top cover locking structure 126 can be a top cover locking structure for locking the top cover of the existing container, which will not be described in detail here. Thus, the top cover 125 covering the top opening 119 can be locked by the top cover locking structure 126 to prevent the top cover 125 from shaking away from the box body during the transportation of the battery.

[0133] Optionally, the protective member 140 is constructed as a fireproof and heat-insulating member made of a fireproof and heat-insulating material. Thus, the battery packaging device also has fireproof and heat-insulating functions, thereby preventing a battery 170 from catching fire and spreading to other batteries 170 transported by other battery packaging devices or other objects transported together.

[0134] Furthermore, the protection member 140 is vermiculite, thereby facilitating the selection of the protection member 140 .

[0135] It is understood that in an embodiment not shown, the protection member may also be other granular objects, such as plastic particles.

[0136] Alternatively, if Fig.13 As shown, the protective member 140 directly contacts the battery 170. At this time, the flexible packaging member 150 wraps the battery 170. The protective member 140 is located between the flexible packaging member 150 and the battery 170. There is a gap between the flexible packaging member 150 and the battery 170. In this way, the flexible packaging member 150 and the battery 170 are separated. A protective member 140 is arranged between the battery 170 and the flexible packaging member 150. The edges of a flexible packaging member 150 are connected to form a closed internal accommodating cavity. All protective members 140 and batteries 170 are located in the internal accommodating cavity. In this way, a flexible packaging member 150 wraps all protective members 140. The protective members 140 and the flexible packaging members 150 are arranged on both sides of the battery 170 along the length direction of the box body 110, the both sides of the battery 170 along the width direction of the box body 110, and the both sides of the battery 170 along the vertical direction. As a result, the structure of the protection unit 130 is simple.

[0137] like Fig.13 As shown, the protection unit 130 also includes a support member 160. The height dimension of the support member 160 is greater than the height dimension of the battery 170. The support member 160 is located in the internal accommodating cavity of the flexible packaging member 150. The support member 160 is used to be arranged between the flexible packaging member 150 and the battery 170 to support the flexible packaging member 150. At this time, the battery 170 is located below the upper end of the support member 160. The protection member 140 is filled in the space formed by the flexible packaging member 150, the battery 170 and the support member 160. In this way, when part of the flexible packaging member 150 is opened, the support member 160 can support the flexible packaging member 150 to prevent the protection member 140 from scattering.

[0138] Further, the support member 160 includes a support top beam and a support top side beam. The length direction of the support top beam is parallel to the width direction of the box body 110. The length direction of the support top side beam is parallel to the length direction of the box body 110. The end of the support top beam is connected to the end of the support top side beam to form a circumferentially closed top frame 162.

[0139] The support member 160 also includes a support column 161. The length direction of the support column 161 is parallel to the vertical direction. The top end of the support column 161 is connected to the top frame 162. The bottom end of the support column 161 is overlapped to the bottom end of the flexible packaging member 150 to be supported on the bottom frame 114 through the bottom end of the flexible packaging member 150. The battery 170 is located between the top frame 162 and the bottom end of the flexible packaging member 150. The battery 170 is located on the inner side of the support column 161 near the center of the top frame 162 in the horizontal direction. As a result, the strength of the support member 160 is large.

[0140] Optionally, refer to Fig.13 , the ends of the protection unit 130 along the horizontal direction include the ends of the protection unit 130 along the first horizontal direction, and the ends of the protection unit 130 along the second horizontal direction. The ends of the box assembly 100 along the horizontal direction include the end wall 112 and the side wall 113. There is a gap between the ends of the protection unit 130 along the horizontal direction and the ends of the box assembly 100 along the horizontal direction. Specifically, there is a gap between the ends of the protection unit 130 along the first horizontal direction and the end wall 112. There is a gap between the ends of the protection unit 130 along the second horizontal direction and the side wall 113. As a result, it is convenient to set the protection unit 130 in the box 110.

[0141] Optionally, there is a gap between the top of the protection unit 130 and the top cover 125 , so that the protection unit 130 can be conveniently disposed in the box body 110 .

[0142] Furthermore, if Fig.13 As shown, the battery packaging device further includes a movable positioning member 180. The movable positioning member 180 is connected to the protection unit 130 and the box assembly 100 to relatively fix the protection unit 130 and the box assembly 100. Thus, the shaking of the protection unit 130 provided with the battery 170 during the transportation of the battery 170 is reduced.

[0143] Specifically, the movable positioning member 180 can be a wooden block. The movable positioning member 180 is arranged between the protection unit 130 and the box assembly 100. For example, part of the movable positioning member 180 can be arranged on the side of the protection unit 130 along the first horizontal direction. Part of the movable positioning member 180 can be arranged on the side of the protection unit 130 along the second horizontal direction. Part of the movable positioning member 180 can be arranged above the protection unit 130. The movable positioning member 180 abuts against the protection unit 130 and the box 110. In this way, the movable positioning member 180 can make the protection unit 130 and the box assembly 100 relatively fixed.

[0144] It is understandable that in an embodiment not shown, the protection unit can be tied to the box body by a binding belt.

[0145] like Fig.13 As shown, the lower surface of the flexible packaging member 150 overlaps the upper surface of the floor laid on the bottom frame 114 to be supported on the upper surface of the floor. In this way, the bottom of the protection unit 130 overlaps the bottom of the box assembly 100. Therefore, no other parts are required between the bottom end of the protection unit 130 and the floor, making it easy to set the protection unit 130 with the battery 170 in the box 110.

[0146] Optionally, the height of the box assembly 100 is 1.5 to 2 times the height of the battery 170 .

[0147] The other configurations of the third embodiment are substantially the same as those of the first embodiment and will not be described in detail herein.

[0148] Fourth embodiment

[0149] In the fourth embodiment, if Fig.14 As shown, the inner surface of the vertical wall 111 is attached to the flexible packaging member 150. The lower surface of the top cover 125 close to the bottom frame is attached to the flexible packaging member 150. In this way, the inner surface of the box assembly (including the inner surface of the vertical wall 111 and the lower surface of the top cover 125) contacts the flexible packaging member 150. The protection unit 130 fills the space formed by the box assembly and the battery 170. In this way, the protection unit 130 provided with the battery 170 in the box 110 can be effectively fixed to prevent the protection unit 130 provided with the battery 170 from shaking.

[0150] In the fourth embodiment, the battery packaging device may not include a positioning member.

[0151] The other configurations of the fourth embodiment are substantially the same as those of the third embodiment and will not be described in detail herein.

[0152] Fifth embodiment

[0153] In the fifth embodiment, if Fig.15 As shown, the protection member 140 is used to contact the battery 170 through the flexible packaging member 150. Thus, the protection member 140 and the flexible packaging member 150 are integrated to wrap the battery 170, which is convenient for installation.

[0154] Optionally, the flexible packaging member 150 wraps the protection member 140 to form a protection subunit. The protection unit includes a plurality of protection subunits 331. The plurality of protection subunits 331 are respectively used to be arranged on the outside of multiple directions of the battery 170 to wrap the battery 170. Specifically, the protection subunit 331 includes a bottom protection subunit 332, an end protection subunit 334, a side protection subunit and a top protection subunit 333. The bottom protection subunit 332, the end protection subunit 334, the side protection subunit and the top protection subunit 333 are removable. The bottom protection subunit 332 is arranged below the battery 170. The top protection subunit 333 is arranged above the battery 170. The end protection subunit 334 is arranged on both sides of the battery 170 along the first horizontal direction. The side protection subunit is arranged on both sides of the battery 170 along the second horizontal direction. Thus, the battery 170 can be loaded and unloaded by removing the top protection subunit 333 , and the flexible packaging component 150 does not need to be damaged during the loading and unloading process of the battery 170 .

[0155] The other configurations of the fifth embodiment are substantially the same as those of the fourth embodiment and will not be described in detail here.
