Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of new energy batteries, and in particular to a battery protection piece. BACKGROUND

[0002] As an important device for energy storage and energy conversion, a battery is prone to short circuit, leakage and other safety problems during transportation if subjected to external impact. Therefore, how to effectively protect the battery during transportation is crucial.

[0003] In the existing protection measures for battery transportation, a protection piece is usually wrapped around the battery for protection. The protection piece mainly includes a hard protection piece and a soft protection piece. The hard protection piece usually provides support protection by using hard materials such as plastic and metal, and the soft protection piece usually provides cushion protection by using soft materials such as foam and bubble cotton.

[0004] However, in the above existing protection measures, the hard protection piece has a large weight, a high cost, and cannot provide cushion protection. Although the soft protection piece can provide certain cushion protection, the soft materials such as foam and bubble cotton have small pores on the surface, which are easy to hide dirt particles. The dirt particles are easy to fall off and contaminate the outer surface of the battery during transportation, and the cleanliness of the battery during transportation cannot be guaranteed, so that the battery needs to be cleaned after transportation, which is time-consuming and laborious. Therefore, how to improve the cleanliness of the battery during transportation while enabling the protection piece to provide cushion protection for the battery has become a technical problem to be solved. CONTENT OF THE UTILITY MODEL

[0005] In view of the above problems, embodiments of the present application provide a battery protection piece. The battery protection piece simultaneously provides a soft cushion layer and an isolation layer. The isolation layer is located on the first side of the soft cushion layer and has no pores on the surface. When the soft cushion layer covers the battery to be transported, the isolation layer separates the soft cushion layer and the isolation layer, so as to provide cushion protection for the battery to be transported through the soft cushion layer, and to prevent the dirt particles in the pores of the soft cushion layer from falling on the outer surface of the battery to be transported through the isolation layer, thereby improving the cleanliness of the battery during transportation while providing cushion protection for the battery.

[0006] In one aspect of embodiments of the present application, a battery protection piece is provided. The battery protection piece includes a soft cushion layer and an isolation layer. The first side of the soft cushion layer is provided with a covering structure for covering the battery to be transported. The isolation layer is attached to the outer surface of the first side of the soft cushion layer, and the isolation layer has no pores, so as to separate the soft cushion layer and the battery to be transported when the soft cushion layer covers the battery to be transported.

[0007] The battery protection piece can provide buffering protection for the battery and improve the cleanliness of the battery during transportation. Meanwhile, the isolation layer separates the soft buffering layer and the battery to be transported, and can also avoid the battery to be transported from rubbing the soft buffering layer to generate debris, thereby further ensuring the cleanliness of the battery to be transported. In addition, the isolation layer has no pores, and its surface is smoother, which also helps to reduce the wear of the battery to be transported during transportation, thereby further prolonging the service life of the battery.

[0008] In an optional manner, the thickness of the isolation layer is 0.1-0.5 mm.

[0009] This manner makes the isolation layer occupy less space while making the overall weight smaller.

[0010] In an optional manner, the isolation layer is a blister film, and the blister film is attached to the first side of the soft buffering layer in a blister-attached manner.

[0011] In this manner, the blister film can be well adsorbed on the mold and the surface of the soft buffering layer, and is tightly attached and not easy to fall off. Moreover, the blister film is flexible in forming, high in manufacturing precision, and has a more flat and beautiful appearance after being attached.

[0012] In an optional manner, the soft buffering layer is an EPS (Expanded Polystyrene) foam layer.

[0013] In this manner, the soft buffering layer has the properties of light weight, heat insulation, energy absorption and buffering, and can effectively protect the battery to be transported from external impact and vibration, while reducing the weight and saving the cost.

[0014] In an optional manner, the isolation layer is any one of a PE (Polyethylene) layer, a PET (Polyethylene Terephthalate) layer, a PVC (Polyvinyl Chloride) layer, or an HDPE (High-Density Polyethylene) layer.

[0015] In this manner, the isolation layer can be set to different materials to have different properties while having the isolation effect, thereby making the setting manner of the isolation layer more flexible.

[0016] In an optional manner, the cover structure includes a plurality of grooves for placing the pole of the battery to be transported. The isolation layer has an inner recess corresponding to the grooves, and the inner recess is attached to the inner wall of the groove to separate the groove from the pole when the groove covers the pole.

[0017] The mode can realize effective isolation, avoid the influence of the stolen particles on the cleanliness of the battery to be transported, and ensure that the battery to be transported can be reliably placed during the transportation process, thereby ensuring the safety of the battery transportation.

[0018] In an optional mode, a step is arranged in the groove, and the step is used to abut against the battery.

[0019] In the mode, the step can provide a stable support surface for the battery to be transported, so that the battery pole or the battery body can be accurately placed in the groove and prevented from moving or tilting during the transportation process. Through the abutment of the step, it can be ensured that the battery is firmly fixed in the groove, thereby ensuring the stability and safety of the transportation.

[0020] In an optional mode, a bending part corresponding to the step is arranged on the inner recess, the bending part is attached to the step, and the corner of the bending part is a circular arc corner.

[0021] In the mode, the groove and the battery can be separated to prevent the battery pole or the battery body from directly contacting the covering structure. At the same time, the corner of the bending part is set as a circular arc corner, which can reduce the forming difficulty of the bending part, reduce stress concentration and wear, avoid damage or deformation of the bending part due to stress concentration, prolong the service life of the isolation layer, and improve the durability and stability of the isolation layer.

[0022] In an optional mode, the inner wall of the groove is arranged as an inclined surface, and the inclined surface has an included angle of 3°-15° with the direction in which the pole is inserted into the groove.

[0023] In the mode, the inclined surface has an appropriate inclination angle, which can make the battery to be transported more easily placed during the insertion of the battery to be transported into the groove, and can make the battery more easily pulled out when the battery to be transported is pulled out from the groove, thereby improving the use convenience of the battery protection piece.

[0024] The battery protection piece provided by the embodiments of the present application simultaneously has a soft buffer layer and an isolation layer, the soft buffer layer can provide buffer protection for the battery to be transported, the isolation layer is located on the first side of the soft buffer layer, and the isolation layer has no pores, so that the soft buffer layer and the isolation layer are separated when the soft buffer layer covers the battery to be transported. Even if the soft buffer layer has pores to accommodate stolen particles, the isolation effect of the isolation layer can also prevent the stolen particles from falling on the outer surface of the battery to be transported, thereby improving the cleanliness of the battery during the transportation process while providing buffer protection for the battery.

[0043] The battery protection device provided by the embodiment of the present application is as shown in Figure 1 、 Figure 2 and Figure 3 . Figure 1 is an explosion schematic view of a battery protection device provided by the embodiment of the present application, Figure 2 is a structural schematic view of a soft buffer layer of the battery protection device involved in the embodiment of the present application, Figure 3 is a structural schematic view of an isolation layer of the battery protection device involved in the embodiment of the present application. The battery protection device comprises a soft buffer layer 10 and an isolation layer 20.

[0044] The soft buffer layer 10 is the main component of the battery protection device, and is used to provide buffering protection for the battery to be transported. The soft buffer layer 10 is made of foam or foam material with high elasticity and good buffering performance, and the soft buffer layer 10 has a certain thickness, so that the soft buffer layer 10 can quickly absorb and disperse energy when subjected to external force impact, effectively reducing the damage to the battery.

[0045] The soft buffer layer 10 can be a foam layer, a foam layer, etc., and the soft buffer layer 10 can be set to different material layers according to requirements, so as to achieve the required performance. For example, in an optional manner, the soft buffer layer 10 is an EPS foam layer, so that the soft buffer layer 10 has the performance of light weight, heat preservation and insulation, energy absorption and buffering, etc., and can effectively protect the battery to be transported from external impact and vibration, while reducing its weight and saving cost.

[0046] The first side of the soft cushion layer 10 is provided with a covering structure for covering the battery to be transported. The structure profile of the covering structure matches the profile of the battery to be transported, so as to ensure that the first side of the soft cushion layer 10 can closely fit the profile of the battery to be transported, and ensure that the battery is firmly fixed during transportation, avoiding damage to the battery due to shaking or collision.

[0047] The covering structure can be formed by one or more planes on the first side of the soft cushion layer 10, and the side of the first side of the soft cushion layer 10 can be completely formed into a covering structure capable of covering the battery to be transported. The covering structure can also take into account the vulnerable parts and wiring ports of the battery, and provide additional protection for these key parts through appropriate thickening, strengthening and avoidance design.

[0048] The isolation layer 20 is attached to the outer surface of the first side of the soft cushion layer 10, and the isolation layer 20 has no pores, so as to separate the soft cushion layer 10 and the battery to be transported when the soft cushion layer 10 covers the battery to be transported.

[0049] The isolation layer 20 plays a role of isolation on the first side of the soft cushion layer 10, so as to completely separate the soft cushion layer 10 from the battery to be transported while the soft cushion layer 10 covers the battery to be transported and provides cushioning protection to the battery to be transported, effectively isolating the direct contact between the battery and the soft cushion layer 10. Even if the soft cushion layer 10 has particles in the pores, the particles will not fall on the outer surface of the battery to be transported and affect the cleanliness of the battery to be transported. At the same time, the isolation layer 20 separates the soft cushion layer 10 and the battery to be transported, which can also avoid the battery to be transported rubbing the soft cushion layer 10 to generate debris, thereby further ensuring the cleanliness of the battery to be transported. In addition, the isolation layer 20 has no pores, and its surface is smoother, which also helps to reduce the wear of the battery to be transported during transportation, further prolonging the service life of the battery.

[0050] When the soft cushion layer 10 closely covers the battery to be transported through the covering structure, the isolation layer 20 serves as a barrier between the soft cushion layer 10 and the battery, separating the two, which not only isolates the direct contact between the battery and the soft cushion layer 10, but also ensures the safety of the battery during transportation. The cushioning performance of the soft cushion layer 10 and the insulation performance of the isolation layer 20 complement each other, and together provide all-round protection for the battery.

[0051] In the embodiment, the isolation layer 20 should have an appropriate thickness. In an optional manner, the thickness of the isolation layer 20 can be 0.1-0.5 mm. In this manner, the thickness of the isolation layer 20 can be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, etc., so as to make the isolation layer 20 occupy less space while making the overall weight of the isolation layer 20 smaller.

[0052] The isolation layer 20 corresponds to a diaphragm covering the first side of the soft buffer layer 10, and the structural contour of the isolation layer 20 matches the contour of the first side of the soft buffer layer 10, so that the isolation layer 20 separates the soft buffer layer 10 and the battery to be transported while not affecting the covering protection of the soft buffer layer 10 to the battery to be transported.

[0053] The isolation layer 20 can be attached to the first side of the soft buffer layer 10 in many ways, and can be vacuum formed attachment. The isolation layer 20 can also be processed and formed by injection molding or other methods to match the contour of the first side of the soft buffer layer 10, and then attached to the first side of the soft buffer layer 10.

[0054] For example, in an optional way, the isolation layer 20 is a vacuum formed film, which is attached to the first side of the soft buffer layer 10 in a vacuum formed manner.

[0055] In this way, the vacuum formed film can be a plastic film similar to a flat plate before forming. When vacuum formed, the plastic film is first heated and softened and attached to the first side of the soft buffer layer 10, and then positive or negative pressure is applied to deform the softened plastic film under the action of air pressure, so that the plastic film is deformed to completely match the structure of the first side of the soft buffer layer 10. The structural contour of the deformed plastic film completely matches the structural contour of the first side of the soft buffer layer 10, and the deformed plastic film is attached to the first side of the soft buffer layer 10. After cooling, the deformed plastic film completes the forming process, thereby forming the vacuum formed film attached to the first side of the soft buffer layer 10.

[0056] In this way, the vacuum formed film can be well adsorbed to the mold and the surface of the soft buffer layer 10, and is tightly attached and not easy to fall off. Moreover, the vacuum formed film is flexible and has high manufacturing precision, and the appearance after attachment is more flat and beautiful.

[0057] In this embodiment, the isolation layer 20 has no pores, and there are many specific ways to set it. For example, in an optional way, the isolation layer 20 is any one of a PE layer, a PET layer, a PVC layer, or an HDPE layer.

[0058] In this way, the isolation layer 20 can be set to different materials to have different properties while having an isolation effect, thereby making the setting of the isolation layer 20 more flexible.

[0059] In this embodiment, the structural contour of the isolation layer 20 matches the structural contour of the first side of the soft buffer layer 10. When the first side of the soft buffer layer 10 has a specific structure for the battery to be transported, the isolation layer 20 should have a structure corresponding to its contour to achieve complete isolation.

[0060] For example, in an alternative way, the battery protection device can be as shown in Figure 1 and Figure 4 as shown in Figure 4 is a partial sectional view of a battery protection device according to an embodiment of the present application. The cover structure includes a plurality of recesses 11 for placing the poles of the batteries to be transported. The isolation layer 20 has inner recesses 21 corresponding to the recesses 11, which are attached to the inner walls of the recesses 11 to separate the recesses 11 from the poles when the recesses 11 cover the poles.

[0061] The number and distribution of the recesses 11 on the cover structure can be determined according to the number and size of the poles of the batteries to be transported. The recesses 11 can be cuboid, cylindrical, or other irregular shapes, and the plurality of recesses 11 can be arranged side by side at intervals so that the recesses 11 can accommodate a sufficient number of batteries to be transported. In addition, the size of the recesses 11 should be such that the recesses 11 can accommodate and secure the poles of the batteries, so as to prevent the batteries to be transported from being damaged due to shaking during transportation.

[0062] The isolation layer 20 has inner recesses 21 corresponding to the recesses 11, and the positions and shapes of these inner recesses 21 correspond one-to-one to the recesses 11 to ensure that each inner recess 21 can be attached to the inner wall of the recess 11, so that the isolation layer 20 can play a role in isolation while not affecting the placement of the poles of the batteries in the recesses 11, thereby achieving effective isolation to prevent foreign particles from affecting the cleanliness of the batteries to be transported, and ensuring that the batteries to be transported can be reliably placed during transportation to ensure the safety of battery transportation.

[0063] In addition, since the poles of the batteries are generally protruding structures provided on the batteries, in order to more stably place the batteries to be transported, a limiting structure such as a step 12 can be provided in the recess 11 to appropriately limit the batteries to be transported.

[0064] For example, in an alternative way, the recess 11 is provided with a step 12 for abutting against the battery. The step 12 can be designed at the bottom or sidewall of the recess 11, and the specific position depends on the shape and size of the poles of the batteries and the battery body.

[0065] In this way, the step 12 can provide a stable support surface for the batteries to be transported, so that the poles of the batteries or the battery body can be accurately placed in the recess 11 and prevented from moving or tilting during transportation. Through the abutment of the step 12, the battery can be securely fixed in the recess 11, thereby ensuring the stability and safety of transportation.

[0066] Further, in order to enable the isolation layer 20 to fully isolate the soft cushion layer 10 and the batteries to be transported, when the recess 11 is provided with a step 12, the isolation layer 20 should also be provided with a structure matching the step 12.

[0067] Exemplarily, in an alternative way, the inner recess 21 is provided with a bending portion 22 corresponding to the step 12, the bending portion 22 is attached to the step 12, and the corner of the bending portion 22 is a circular arc corner.

[0068] In this way, the bending portion 22 on the inner recess 21 is matched with the step 12 in the groove 11, which ensures that the bending portion 22 can be closely attached to the step 12, thereby separating the groove 11 and the battery, preventing the battery pole or the battery body from directly contacting the covering structure, which can not only enhance the stability of the battery to be transported placed in the groove 11, but also avoid the influence of the dirt particles on the cleanliness of the battery during the transportation of the battery.

[0069] The corner of the bending portion 22 is set as a circular arc corner, which can reduce the forming difficulty of the bending portion 22, reduce stress concentration and wear, avoid damage or deformation of the bending portion 22 due to stress concentration, prolong the service life of the isolation layer 20, and improve the durability and stability of the isolation layer 20.

[0070] In addition, when the battery to be transported is protected by being accommodated in the groove 11, the pole of the battery to be transported needs to be inserted into the groove 11 for placement. In order to facilitate the battery to be transported to be pulled out of the groove 11 more conveniently, the groove 11 can be set as a structure facilitating the battery to be pulled out, similar to the setting mode of the draft angle.

[0071] Exemplarily, in an alternative way, the inner wall of the groove 11 is set as an inclined surface, and the inclined surface has an included angle of 3°-15° with the direction of the pole inserted into the groove 11. Specifically, the included angle between the inclined surface and the direction of the pole inserted into the groove 11 can be 3°, 15°, or any angle between 3° and 15°. Since the profile of the inner recess 21 matches the profile of the groove 11, correspondingly, the inner wall of the inner recess 21 is also an inclined surface, and the inclination angle of the inclined surface, i.e., the included angle between the inclined surface and the direction of the pole inserted into the inner recess 21, is 3°-15°.

[0072] In this way, the inclined surface has an appropriate inclination angle, which can make the battery to be transported more easily placed during the insertion of the battery to be transported into the groove 11, and make the battery more easily pulled out when the battery to be transported is pulled out of the groove 11, thereby improving the use convenience of the battery protection piece.

[0073] In summary, the battery protection device described above is provided with a soft buffer layer and an isolation layer, the soft buffer layer can provide buffering protection for the battery to be transported. The isolation layer is located on the first side of the soft buffer layer and has no pores on the isolation layer, so that the soft buffer layer and the isolation layer are separated when the soft buffer layer covers the battery to be transported. Even if the soft buffer layer has pores to accommodate the stolen particles, the isolation effect of the isolation layer can prevent the stolen particles from falling on the outer surface of the battery to be transported, so as to provide buffering protection for the battery and improve the cleanliness of the battery during transportation.
