Description

Technical Field

[0001] The invention belongs to the technical field of material turnover, in particular to a material turnover box. Background Art

[0002] Material turnover boxes are mainly used to store, protect and transport various materials, such as parts, tools, components, etc. Among them, since the structure of battery cells is relatively fragile and easily affected by external forces, turnover boxes must be used for transportation during the transportation process.

[0003] A patent application with publication number CN206231749U discloses an anti-static turnover material box, including a box body, wherein the box body is composed of an external baffle, a plurality of internal partitions and a bottom plate, and the anti-static hollow plate is folded to form the external baffle, and the bottom plate is fixedly connected to the bottom edge of the external baffle. The material box can prevent quality risks caused by collision of electronic materials during the production process, and because of the fixed position, the position of the material in the material box will be memorized during the processing process, and the material can be accurately and quickly taken without additional searching actions, which meets the requirements of the principle of motion economy in the production process, can reduce unnecessary searching action waste of production personnel, and improves production efficiency.

[0004] There are still some problems in the actual application of the above scheme. When using the above-mentioned turnover material box to store and transport battery cells, since the battery cells need to fit together with the material partitions and some gases will be generated inside the battery cells, these gases will cause the battery cells to generate a certain amount of heat, thereby affecting the safety of the battery cells. Therefore, the top of the turnover material box will be set to be open so that the top of the battery cells can remain breathable when stored. However, if the turnover material box falls over during transportation, the battery cells will fall out from the open end, or some debris will be smashed into the interior of the turnover material box, causing damage to the battery cells.

[0005] To this end, the present invention provides a material turnover box. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0022] like Figures 1 to 11As shown, a material turnover box according to an embodiment of the present invention comprises a shell 1, a placement structure 2 is arranged inside the shell 1, the placement structure 2 comprises a material partition 22, the material partition 22 is arranged inside the shell 1, a sponge pad 21 is arranged between the material partition 22 and the shell 1, and a protective structure 3 is arranged inside the material partition 22; the protective structure 3 comprises: a protective plate 305, the protective plate 305 is rotatably connected to the inside of the material partition 22, and the protective plate 305 is parallel to the side wall of the material partition 22 in the initial state; the second volume Spring 315, the second coil spring 315 is arranged at one end of the protective plate 305, and the second coil spring 315 is in a taut state in the initial state; the sensing ball 314, the sensing ball 314 is slidably connected to the inside of the material partition 22; the trigger plate 311, the trigger plate 311 is rotatably connected to the inside of the material partition 22, and the trigger plate 311 contacts the moved sensing ball 314; the abutment plate 310, the abutment plate 310 is connected to the trigger plate 311, and the abutment plate 310 contacts the protective plate 305 in the initial state.

[0023] Specifically, a material turnover box of the scheme is mainly used for storing and transporting battery cells 4. When in use, the material partition 22 is first placed into the interior of the shell 1, and then the sponge pad 21 is placed between the material partition 22 and the shell 1 to reduce the friction between the material partition 22 and the shell 1, thus forming a battery cell 4 turnover box. Subsequently, several battery cells 4 are placed in the gaps of the material partition 22 to complete the storage of the battery cells 4. Due to the special properties of the battery cells 4, the top of the turnover box needs to be set to an open shape to ensure the air permeability of the battery cells 4. At this time, The turnover box can be transported, but during transportation, if the turnover box tilts due to a transportation accident, the battery cells 4 will fall from the opening above the turnover box, or some debris will hit the inside of the turnover box, causing damage to the battery cells 4. If a layer of protective net with mesh holes is added, although it can ensure that the battery cells 4 will not fall from the inside of the turnover box when the turnover box falls, some flying fragments caused by the fall and collision are easy to fly into the inside of the turnover box at high speed through the mesh holes and scratch the surface of the battery cells 4. For this reason, A protective structure 3 is provided inside the material partition plate 22. During the transportation of the turnover box, the protective plate 305 will be parallel to the side of the battery cell 4. The protective plate 305 will neither affect the storage of the battery cell 4 nor the heat dissipation of the battery cell 4. When the turnover box is tilted, the induction ball 314 will move along the inside of the material partition plate 22 toward the direction of the trigger plate 311. After contacting the trigger plate 311, the trigger plate 311 will drive the abutment plate 310 to rotate, so that the abutment plate 310 rotates until it is not in contact with the protective plate 305. Without the restraint of the abutment plate 310, the second coil spring 315 will release the elastic force, and finally drive the protective plate 305 to cover the top of the battery cell 4, thereby preventing the battery cell 4 from being damaged. After tipping over, when the turnover box remains still, the turnover box can be put upright, and then the material partition 22 together with the battery cell 4 can be taken out. The battery cell 4 inside is not damaged due to the protection of the protective plate 305, and this short-time sealing will not have a significant impact on the battery cell 4, thereby ensuring the safety of the turnover box when storing and transporting the battery cell 4.

[0024] like Figures 1 to 6 As shown, the protective structure 3 also includes a sliding ramp 308, which is opened inside the material partition 22, and the sensing ball 314 slides on the surface of the sliding ramp 308. A placement groove is opened on the surface of the sliding ramp 308 near the initial position of the sensing ball 314. The interior of the sliding ramp 308 is rotatably connected to a rotating ring 309, and the trigger plate 311 and the abutment plate 310 are both connected to the rotating ring 309.

[0025] Specifically, during the transportation of the turnover box, the sensing ball 314 will be placed in the placement groove opened on the surface of the sliding ramp 308. Then, if the turnover box is tilted, the sensing ball 314 will move along the surface of the sliding ramp 308 toward the trigger plate 311. Then, after the sensing ball 314 contacts the trigger plate 311, the trigger plate 311 and the abutment plate 310 will rotate around the rotating ring 309 as the axis, thereby automatically popping out the protective plate 305 to protect the battery cell 4.

[0026] like Figures 1 to 6 As shown, the sliding ramp 308 is set in an inclined state, and the higher end is close to the trigger piece 311.

[0027] Specifically, since the automatic pop-up of the protective plate 305 is achieved by the contact between the sensing ball 314 and the trigger plate 311, and the sliding ramp 308 is set to an inclined state, the protective plate 305 can be prevented from being accidentally activated when passing through a road with a large slope during transportation.

[0028] like Figures 1 to 8 As shown, the upper end of the material partition 22 is slidably connected to the lifting rod 307, the lower end of the lifting rod 307 is provided with a fixed block 312, and the fixed block 312 contacts the sensing ball 314 after moving, the upper end of the lifting rod 307 is provided with a rubber ball 319, and the upper surface of the material partition 22 is provided with a first slot 320 at one end close to the lifting rod 307, and the rubber ball 319 is engaged with the first slot 320.

[0029] Specifically, by setting the fixed block 312, when the turnover box is not in use, the lifting rod 307 is pressed downward, and the lifting rod 307 will drive the rubber ball 319 to move downward together with the fixed block 312. Then, when the rubber ball 319 is inserted into the first slot 320, the fixed block 312 will also move to contact the sensing ball 314, so that the sensing ball 314 can be fixed and the protective plate 305 will not pop out automatically.

[0030] like Figures 1 to 8 As shown, a connecting plate 313 is provided inside the material partition 22 to slide up and down, a limit spring 321 is provided at the upper end of the connecting plate 313, an extension plate 317 is connected to the lower end of the connecting plate 313, a rack 318 is provided at one end of the extension plate 317 close to the rotating ring 309, a gear 316 is provided at one end of the rotating ring 309, and the gear 316 is meshed with the rack 318.

[0031] Specifically, since the direction of tilting may be random when the turnover box is tilted, by setting a connecting plate 313, when the turnover box is not tilted along the direction of the sliding ramp 308, the sensing ball 314 will move toward the direction of the connecting plate 313, and finally contact the connecting plate 313 and push the connecting plate 313 to move toward the direction close to the first slot 320. At this time, the connecting plate 313 will drive the rack 318 to move together through the extension plate 317, so that the rack 318 is meshed with the gear 316 and drives the rotating ring 309 to rotate. At this time, the protective plate 305 will also pop out automatically, so that when the turnover box tilts to either side, the protective plate 305 can automatically pop out, thereby protecting the battery cell 4.

[0032] like Figures 1 to 11 As shown, a sliding groove 323 is provided at one end of the fixed block 312 close to the connecting plate 313, a second clamping groove 324 is provided on the inner wall of the sliding groove 323, a connecting frame 322 is provided at one end of the connecting plate 313 close to the fixed block 312, and the connecting frame 322 slides on the inner wall of the sliding groove 323, both ends of the connecting frame 322 are slidably connected with cylindrical buckles 325, and the cylindrical buckle 325 is clamped with the second clamping groove 324, and one end of the cylindrical buckle 325 is connected to a return spring 326.

[0033] Specifically, in the initial state, the fixed block 312 will contact the sensing ball 314. Then, when transporting the turnover box, the rubber ball 319 will be pulled out of the first slot 320 and the fixed block 312 will be pulled upward, so that the connecting frame 322 contacts the sliding slot 323. Since a return spring 326 is provided at one end of the cylindrical buckle 325, the cylindrical buckle 325 will be squeezed into the interior of the connecting frame 322 at this time, and the connecting frame 322 will slide on the inner wall of the sliding slot 323. Then, during the movement, the cylindrical buckle 325 will be stuck into the interior of the second slot 324, so that the fixed block 312 is connected to the connecting plate 313. If the turnover box is tilted at this time, the sensing ball 314 will contact the fixed block 312 and drive the protective plate 305 to pop out automatically. If the sensing ball 314 needs to be fixed, just press the lifting rod 307 downward.

[0034] like Figures 1 to 6 As shown, a plurality of buffer pads 306 are provided on the surface of the protection plate 305 .

[0035] Specifically, by providing a plurality of buffer pads 306 , when the protective plate 305 automatically pops up, the buffer pads 306 on the surface of the protective plate 305 will contact the battery cell 4 , which can not only limit the upper part of the battery cell 4 but also reduce damage to the battery cell 4 . Embodiment 2

[0036] like Figures 1 to 4As shown, in comparison with Example 1, another embodiment of the present invention is that the lower end of the material partition plate 22 is rotatably connected with a positioning clip 301, and the positioning clip 301 is "L" shaped.

[0037] Specifically, by providing a positioning clamp 301, when the battery cell 4 is placed into the turnover box and contacts the material partition 22, the longer end of the positioning clamp 301 located at the bottom of the turnover box will first contact the battery cell 4, causing the positioning clamp 301 to rotate, thereby clamping the two ends of the battery cell 4, and the placement position of the battery cell 4 can be positioned so that the battery cell 4 can be located at the center of the material partition 22.

[0038] like Figures 1 to 4 As shown, a rotating shaft 304 is provided at one end of the positioning clamp 301 , a first coil spring 303 is sleeved on the arc surface of the rotating shaft 304 , and one end of the first coil spring 303 is in contact with the material partition plate 22 .

[0039] Specifically, by setting a first coil spring 303 at one end of the positioning clip 301, the positioning clip 301 is set to an inclined state in the initial state, so that when the battery cell 4 contacts the positioning clip 301, the battery cell 4 will not accidentally touch the shorter end of the positioning clip 301, thereby causing wear, and the first coil spring 303 can keep the positioning clip 301 in an inclined state.

[0040] like Figures 1 to 4 As shown, a flat opening 302 is formed at a longer end of the positioning clamp 301 , and the flat opening 302 is parallel to the bottom of the material partition plate 22 in an initial state.

[0041] Specifically, by setting the flattening opening 302, the flattening opening 302 is parallel to the bottom of the material partition 22 in the initial state, so that when the battery cell 4 contacts the positioning clamp 301, the contact surface is a plane, which can reduce damage to the battery cell 4.

[0042] Working principle: When in use, first put the material partition 22 into the interior of the shell 1, and then put the sponge pad 21 between the material partition 22 and the shell 1 to reduce the friction between the material partition 22 and the shell 1, thus forming a battery cell 4 turnover box, and then put a number of battery cells 4 into the gaps of the material partition 22 to complete the storage of the battery cells 4. During transportation, if the turnover box is tilted due to a transportation accident, the sensing ball 314 will move along the surface of the sliding ramp 308 toward the trigger sheet 311, and then after the sensing ball 314 contacts the trigger sheet 311, the trigger sheet 311 and the abutment sheet 310 will rotate with the rotating ring 309 as the axis, so that the abutment sheet 310 rotates until it is no longer in contact with the protective plate 305. Since the protective plate 305 is no longer restrained by the abutment sheet 310, the second volume The spring 315 will release its elastic force, and eventually drive the protective plate 305 to cover the top of the battery cell 4, thereby preventing the battery cell 4 from being damaged. In addition, since the direction of inclination may be random when the turnover box is tilted, by setting the connecting plate 313, when the turnover box is not tilted along the direction of the sliding ramp 308, the sensing ball 314 will move toward the fixed block 312, and eventually contact the fixed block 312 and push the connecting plate 313 to move toward the direction close to the first slot 320. At this time, the connecting plate 313 will drive the rack 318 to move together through the extension plate 317, so that the rack 318 is meshed with the gear 316 and drives the rotating ring 309 to rotate. At this time, the protective plate 305 will also pop out automatically, so that when the turnover box is tilted to any side, the protective plate 305 can automatically pop out, thereby protecting the battery cell 4.
