Description

Technical Field

[0001] This application relates to the technical field of new energy battery packaging, and particularly to a battery packing box with a built-in shock-absorbing mechanism. Background Art

[0002] At present, the global energy and environmental systems are facing huge challenges. To protect the environment, the country vigorously promotes the development of new energy. Among them, new energy vehicles have been vigorously developed, and the new energy batteries in new energy vehicles are core components. To facilitate the transportation of batteries, workers usually design paper packing boxes to package and transport new energy batteries. Since new energy batteries are vulnerable and precision components, protection devices need to be designed to protect new energy batteries.

[0003] Generally, foam boards are used as fillers in new energy battery packing boxes. Foam boards have the characteristics of being convenient to process and having a certain buffering capacity. Therefore, they are often used as fixing and buffering protection components for batteries. However, foam boards are also vulnerable components. In certain cases, the ability of foam boards to protect batteries depends on the structural strength of the packing box.

[0004] During the driving of transport vehicles, it is inevitable that the vehicles will jolt due to uneven roads, and the packing boxes will also jolt with the transport vehicles, resulting in the possible damage of the packing boxes due to jolts, and thus the possible damage of the batteries, which has deficiencies. Utility Model Content

[0005] In order to reduce the possibility of battery damage, this application provides a battery packing box with a built-in shock-absorbing mechanism.

[0006] The battery packing box with a built-in shock-absorbing mechanism provided by this application adopts the following technical solutions:

[0007] A battery packing box with a built-in shock-absorbing mechanism includes a cardboard box body. A bottom plate is arranged inside the cardboard box body. Positioning plates are symmetrically arranged on the bottom plate with respect to its center line. A positioning component for fixing the battery is arranged on the positioning plates. A shock-absorbing component for reducing the vibration of the battery is arranged on the positioning plates. The positioning component includes side plates, support seats and pressing plates. The side plates are slidably arranged on the positioning plates. Side fixing members for driving the side plates to press against the side walls of the battery are arranged on the positioning plates. The support seats are used to support the battery. The pressing plates are detachably arranged on the positioning plates, and the pressing plates are used to press the battery against the support seats.

[0008] By adopting the above technical solution, the worker first places the battery on the support seat, then the worker uses the side fixing member to make the side plate abut against the side wall of the battery, and finally presses the battery onto the support seat through the pressing plate, so as to realize the preliminary fixation of the battery. Then, the shock-absorbing component reduces the shock force suffered by the battery due to bumps. At the same time, the stable structure formed by the bottom plate, the positioning plate and the pressing plate keeps the battery in a stable structure, which is beneficial to reducing the possibility of battery damage.

[0009] Optionally, the shock-absorbing component includes a main airbag arranged on the bottom plate, the main airbag is used to support the bottom of the battery, the support seat is slidably mounted between the two positioning plates, a sliding groove for the support seat to slide is formed on the positioning plate, a first compression spring is provided between the support seat and the bottom plate, a guide rod is arranged on the side of the pressing plate facing the battery, a pressing frame plate is slidably arranged on the guide rod, and a second compression spring is provided between the pressing frame plate and the pressing plate.

[0010] By adopting the above technical solution, the worker first places the battery on the support seat. Affected by the gravity of the battery, the support seat descends vertically, compressing the first compression spring. Then the worker fixes the pressing plate on the positioning plate, making the pressing frame plate press on the top of the battery. During the process of fixing the pressing plate on the positioning plate, the second compression spring is compressed. At the same time, under the positioning action of the side plate, when the battery bumps with the transport vehicle, through the continuous deformation of the first compression spring and the second compression spring, the degree of battery bumping is reduced, and further the possibility of battery damage due to bumps is reduced.

[0011] Optionally, a slider is rotatably arranged on the support seat, the slider is slidably matched with the sliding groove, the cross section of the support seat is C-shaped, a load-bearing plate and a side vertical plate are respectively rotatably arranged at both ends of the C-shaped support seat, the load-bearing plate is used to support the bottom of the battery, and the side vertical plate is used to abut against the side wall of the battery.

[0012] By adopting the above technical solution, since the sizes of different batteries are different, when the battery drives the support seat to descend, the support seat rotates around the rotation center of the slider. On the one hand, the load-bearing plate rotates and always supports the bottom of the battery. On the other hand, the side vertical plate rotates and always abuts against the side wall of the battery, so as to realize the fixation of batteries of different sizes, which is beneficial to improving the applicability of the installation of different batteries.

[0013] Optionally, an air cylinder is vertically arranged on the bottom plate, a first hose is connected between the bottom of the air cylinder and the main airbag, a pneumatic column is slidably arranged coaxially on the air cylinder, and one end of the pneumatic column facing away from the first hose is arranged on the slider.

[0014] By adopting the above technical solution, when the support base descends under the gravity of the battery, the support base drives the air compression column to move downward through the slider, and the air compression column presses the air in the air cylinder into the main airbag through the first hose. The main airbag expands to support the bottom of the battery, thereby alleviating the descending speed of the battery. When the transport vehicle causes the packaging box to jolt, the expansion of the main airbag is conducive to slowing down the vertical descending speed of the battery.

[0015] Optionally, the side fixing member includes a secondary airbag disposed between the positioning plate and the side plate, and a second hose is connected between the secondary airbag and the main airbag.

[0016] By adopting the above technical solution, after the air in the air cylinder enters the main airbag through the first hose, a part of the gas in the main airbag flows into the secondary airbag through the second hose. The secondary airbag expands and drives the side plate to press tightly against the side wall of the battery, thereby increasing the friction force between the side plate and the battery and further reducing the descending speed of the battery.

[0017] Optionally, an outer tube is vertically arranged on the bottom plate, the main airbag is arranged inside the outer tube, a top plate is arranged on the main airbag, the top plate is used to support the bottom of the battery, and the top plate is slidably matched with the outer tube.

[0018] By adopting the above technical solution, after the air in the cylinder enters the main airbag through the first hose, under the constraint of the outer tube, the main airbag expands along the axis direction of the outer tube, and the main airbag pushes the top plate to slide. The top plate supports the bottom of the battery, thereby realizing stable buffering of the battery.

[0019] Optionally, torsion springs are arranged between the load-bearing plate and the support base and between the load-bearing plate and the slider, and the torsion springs keep the load-bearing plate horizontal.

[0020] By adopting the above technical solution, under the action of the torsion spring, during the process of the worker placing the battery, the load-bearing plate always remains horizontal, which is convenient for the load-bearing plate to support the bottom of the battery.

[0021] Optionally, a buffer plate is arranged on the pressing frame plate, and the buffer plate is used to abut against the battery.

[0022] By adopting the above technical solution, the possibility of the battery being damaged is further reduced.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. First, the worker places the battery on the support seat. Then, the worker uses the side fastener to make the side plate press against the side wall of the battery. Finally, the battery is pressed tightly on the support seat through the pressing plate, thereby achieving the preliminary fixation of the battery. Then, the shock absorption component is used to reduce the shock force suffered by the battery due to bumps. At the same time, the stable structure formed by the bottom plate, the positioning plate and the pressing plate keeps the battery in a stable structure, which is beneficial to reducing the possibility of battery damage;

[0025] 2. First, the worker places the battery on the support seat. Affected by the gravity of the battery, the support seat descends vertically, compressing the first compression spring. Then, the worker fixes the pressing plate on the positioning plate, making the pressing frame plate press on the top of the battery. During the process of fixing the pressing plate on the positioning plate, the second compression spring is compressed. At the same time, under the positioning action of the side plate, when the battery bumps with the transport vehicle, through the continuous deformation of the first compression spring and the second compression spring, the degree of battery bumping is reduced, thereby reducing the possibility of battery damage due to bumps;

[0026] 3. When the support seat descends under the gravity of the battery, the support seat drives the air compression column to move downward through the slider. The air compression column presses the air in the air cylinder into the main air bag through the first hose. The main air bag expands to support the bottom of the battery, thereby alleviating the descending speed of the battery. When the transport vehicle causes the packaging box to bump, the expansion of the main air bag is beneficial to slowing down the vertical descending speed of the battery. Description of the Drawings

Detailed Embodiments

[0032] The following will further describe the present application in detail with reference to the accompanying Figures 1-4 drawings.

[0033] An embodiment of the present application discloses a battery packing box with a built-in shock absorption mechanism.

[0034] Referring to Figure 1 , a battery packing box with a built-in shock absorption mechanism includes a cardboard box body 1. A horizontal bottom plate 2 is arranged inside the cardboard box body 1. Two vertical positioning plates 3 are symmetrically bolted on the bottom plate 2 with respect to its center line. A positioning component 4 for fixing the battery 0 is arranged on the positioning plate 3, and a shock absorption component 5 for reducing the vibration of the battery 0 is arranged on the positioning plate 3.

[0035] Referring to Figure 2 , Figure 3 and Figure 4 , the positioning component 4 includes a side plate 41, a support seat 42 and a pressing plate 43. The side plate 41 is horizontally slidably arranged on the positioning plate 3. A receiving groove 16 for the side plate 41 to slide is opened on the positioning plate 3. The side plate 41 can be made of rubber material. A side fastener 44 for driving the side plate 41 to press against the side wall of the battery 0 is arranged on the positioning plate 3. The support seat 42 is used to support the battery 0. The pressing plate 43 is bolted to the top of the positioning plate 3, and the pressing plate 43 is used to press the battery 0 onto the support seat 42.

[0036] After the worker opens the cardboard box body 1, the battery 0 is placed on the support seat 42. Then, the side plate 41 is pressed against the outer side wall of the battery 0 through the side fastener 44. Finally, the pressing plate 43 is pressed against the top of the battery 0 and the pressing plate 43 is bolted to the positioning plate 3 to fix the battery 0.

[0037] Referring to Figure 2 , Figure 3 and Figure 4 , the shock absorption component 5 includes a main airbag 51 arranged on the bottom plate 2. A vertical outer tube 12 is bolted on the bottom plate 2. The main airbag 51 is placed inside the outer tube 12. A top plate 13 is bonded to the main airbag 51. The top plate 13 is slidably matched with the outer tube 12. The top plate 13 is used to support the bottom of the battery 0. The top plate 13 can be made of hard plastic material.

[0038] Referring to Figure 2 , Figure 3 and Figure 4 , the support seat 42 is slidably mounted between the two positioning plates 3. The support seat 42 is arranged on both sides of the battery 0. A chute 52 is vertically opened on the positioning plate 3. A slider 6 is rotatably arranged on the support seat 42. The slider 6 is slidably matched with the chute 52. A first compression spring 53 is supported between the support seat 42 and the bottom plate 2.

[0039] Referring to Figure 2 , Figure 3And Figure 4 On one side of the pressing plate 43 facing the battery 0, a vertical guide rod 54 is welded. A pressing frame plate 55 is slidably arranged on the guide rod 54. A second compression spring 56 is propped between the pressing frame plate 55 and the pressing plate 43. A buffer plate 15 is adhered to the pressing frame plate 55. The buffer plate 15 can be made of flexible rubber material and is used to abut against the battery 0.

[0040] Refer to Figure 2 、 Figure 3 And Figure 4 , the cross-section of the support seat 42 is C-shaped. At both ends of the C-shape of the support seat 42, a load-bearing plate 7 and a side-standing plate 8 are respectively rotatably arranged. The load-bearing plate 7 is used to support the bottom of the battery 0, and the side-standing plate 8 is used to abut against the side wall of the battery 0. Torsion springs 14 are arranged between the load-bearing plate 7 and the support seat 42, between the load-bearing plate 7 and the slider 6, and between the load-bearing plate 7 and the side-standing plate 8. The torsion springs 14 keep the load-bearing plate 7 in a horizontal state.

[0041] Refer to Figure 2 、 Figure 3 And Figure 4 , a vertical air cylinder 9 is bolted to the bottom plate 2. A first hose 10 is connected between the bottom of the air cylinder 9 and the main air bag 51. A pneumatic column 11 is coaxially slidably arranged on the air cylinder 9. One end of the pneumatic column 11 facing away from the first hose 10 is bolted to the slider 6. The side fixing member 44 includes a secondary air bag 441 placed in the receiving groove 16 and located between the positioning plate 3 and the side plate 41. A second hose 442 is connected between the secondary air bag 441 and the main air bag 51.

[0042] As the battery 0 is placed on the load-bearing plate 7 of the support seat 42, the support seat 42 vertically descends under the cooperation of the slider 6 and the chute 52, and at the same time, the support seat 42 rotates around the rotation center of the slider 6. Meanwhile, the load-bearing plate 7 rotates and always props against the bottom of the battery 0, and the side-standing plate 8 rotates and always abuts against the side wall of the battery 0, so that the battery 0 is always in a clamped state.

[0043] The support seat 42 descends to squeeze the first compression spring 53, and the first compression spring 53 deforms until the battery 0 no longer descends. Then the worker presses the pressing plate 43 on the top of the battery 0. The buffer plate 15 on the pressing frame plate 55 first contacts the battery 0. As the pressing plate 43 is further pressed down, the second compression spring 56 is continuously compressed and deformed until the worker bolts the pressing plate 43 to the positioning plate 3, and the battery 0 is fixed by the deformation forces of the first compression spring 53 and the second compression spring 56.

[0044] During the process of the support base 42 descending until it stops, the support base 42 drives the air compression column 11 to move downward through the slider 6. The air compression column 11 presses the air in the air cylinder 9 into the main airbag 51 through the first hose 10. The main airbag 51 expands, and under the restraint of the outer tube 12, the main airbag 51 supports the bottom of the battery 0 through the top plate 13, thereby reducing the descending speed of the battery 0.

[0045] Among the air entering the main airbag 51 from the air cylinder 9, a part flows into the secondary airbag 441 through the second hose 442. The secondary airbag 441 expands and under the restraint of the accommodation groove 16, it pushes the side plate 41 to press tightly against the outer side wall of the battery 0, and by increasing the frictional force between the side plate 41 and the battery 0, the descending speed of the battery 0 is reduced.

[0046] When the transport vehicle jolts, through the continuous deformation of the first compression spring 53 and the second compression spring 56, and the change in the gas pressure in the main airbag 51 and the secondary airbag 441, the shock absorption effect on the battery 0 is achieved.

[0047] The implementation principle of the battery packaging box with a built-in shock absorption mechanism in this application embodiment is as follows: After the worker opens the carton body 1, the battery 0 is placed on the support base 42, then the side plate 41 is pressed tightly against the outer side wall of the battery 0 through the side fastener 44, and finally the pressing plate 43 is pressed tightly against the top of the battery 0 and the pressing plate 43 is bolted to the positioning plate 3, thereby achieving a fixing effect on the battery 0.

[0048] As the battery 0 is placed on the load-bearing plate 7 of the support base 42, the support base 42 vertically descends by relying on the cooperation between the slider 6 and the sliding groove 52. At the same time, the support base 42 rotates around the rotation center of the slider 6. Meanwhile, the load-bearing plate 7 rotates and always supports the bottom of the battery 0, and the side standing plate 8 rotates and always abuts against the side wall of the battery 0, keeping the battery 0 in a clamped state all the time.

[0049] The support base 42 descends and presses the first compression spring 53, and the first compression spring 53 deforms until the battery 0 stops descending. Then the worker presses the pressing plate 43 on the top of the battery 0. The buffer plate 15 on the pressing frame plate 55 first contacts the battery 0. As the pressing plate 43 continues to be pressed down, the second compression spring 56 is continuously compressed and deformed until the worker bolts the pressing plate 43 to the positioning plate 3, and the battery 0 is fixed by the deformation force of the first compression spring 53 and the second compression spring 56.

[0050] During the process of the support base 42 descending until it stops, the support base 42 drives the air compression column 11 to move downward through the slider 6. The air compression column 11 presses the air in the air cylinder 9 into the main airbag 51 through the first hose 10. The main airbag 51 expands, and under the restraint of the outer tube 12, the main airbag 51 supports the bottom of the battery 0 through the top plate 13, thereby reducing the descending speed of the battery 0.

[0051] Among the air entering the main airbag 51 from the air pump 9, a part flows into the secondary airbag 441 through the second hose 442. The secondary airbag 441 expands and under the restraint of the receiving groove 16, pushes the side plate 41 to press against the outer wall of the battery 0, increasing the friction force between the side plate 41 and the battery 0 and reducing the descending speed of the battery 0.

[0052] When the transport vehicle jolts, through the continuous deformation of the first compression spring 53 and the second compression spring 56 and the change of the gas pressure in the main airbag 51 and the secondary airbag 441, the shock absorption effect on the battery 0 is achieved.

[0053] The above are all the preferred embodiments of this application. The protection scope of this application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
