TECHNICAL FIELD

[0001] The utility model relates to double -sided adhesive tape technical field especially relates to a power battery shockproof double -sided adhesive tape. BACKGROUND

[0002] Power battery is the power source of the tool, and is mostly used for providing power for electric automobile, electric train, electric bicycle and golf cart. Power battery is the core component of new energy automobile and is the important direction of future energy transformation.

[0003] The parts inside the power battery are often fixed by double -sided adhesive, and the power battery is often affected by vibration when running with the vehicle, and the existing double -sided adhesive has poor buffering and shock -absorbing performance and insufficient protection, therefore, in view of the above status, it is urgent to develop a power battery shockproof double -sided adhesive tape with good buffering and shock -absorbing performance and good protection effect when fixing the power battery, to overcome the deficiencies in current practical application and meet the current demand. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a power battery shockproof double -sided adhesive tape to solve the problems in the above background art.

[0005] In order to achieve the above object, the utility model adopts the following technical scheme:

[0006] A power battery shockproof double -sided adhesive tape, including rubber layer, bubble cotton layer, fire -retardant layer, base material layer and adhesive layer, the upper and lower sides of rubber layer are all provided with a bubble cotton layer, a plurality of insertion blocks are provided on the bubble cotton layer, a plurality of insertion slots for the insertion of insertion block are provided on the rubber layer, the insertion block is inserted into the insertion slot and is fixed by glue, a plurality of recessed holes are provided on the bubble cotton layer, one fire -retardant layer is fixed on each bubble cotton layer, one base material layer is fixed on each fire -retardant layer, and one adhesive layer is fixed on each base material layer.

[0007] Preferably, the length of the insertion block is less than the depth of the insertion slot, so that there is a certain gap after the insertion block is inserted into the insertion slot.

[0008] Preferably, the fire -retardant layer is made of fire -retardant polyester.

[0009] Preferably, the base material layer is made of polytetrafluoroethylene.

[0010] Preferably, the adhesive layer is made of acrylic pressure sensitive adhesive.

[0011] The beneficial effects of this utility model are as follows: This double-sided shock-absorbing tape for power batteries, when used, uses two adhesive layers to bond and fix the components of the power battery. When vibration occurs, the rubber layer and foam layer deform to absorb the vibration. The foam layer is connected to the rubber layer via interlocking blocks, making it easier for the foam layer to deform laterally on the rubber layer, thus improving the deformation buffering capacity. The concave holes provide a larger deformation space within the foam layer itself. Simultaneously, the concave holes also hinder the propagation of vibration within the foam layer, changing the direction of vibration transmission. This causes the vibration to be reflected and refracted multiple times within the foam layer, thereby fully absorbing the vibration and reducing the transmission of vibration to external objects. In summary, this utility model has good buffering and shock absorption performance and provides good protection when bonding and fixing power batteries. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] See Figs. 1-3In this embodiment of the present invention, a double-sided shockproof tape for power batteries includes a rubber layer 1, a foam layer 2, a flame-retardant layer 3, a substrate layer 4, and an adhesive layer 5. A foam layer 2 is provided on both the upper and lower sides of the rubber layer 1. Multiple insertion blocks 202 are provided on the foam layer 2, and multiple insertion slots 101 for inserting the insertion blocks 202 are provided on the rubber layer 1. The insertion blocks 202 are inserted into the insertion slots 101 and fixed with adhesive. The length of the insertion block 202 is less than the depth of the insertion slot 101, leaving a certain gap after the insertion block 202 is inserted into the slot 101. The foam layer 2 is connected to the rubber layer 1 through the insertion blocks 202, making it easier for the foam layer 2 to deform laterally on the rubber layer 1, thus improving the deformation buffering capacity. Multiple recesses 201 are provided on the foam layer 2, which allow for greater deformation space within the foam layer 2 itself. The concave holes 201 can also hinder the propagation of vibration within the foam layer 2, changing the direction of vibration transmission, so that the vibration is reflected and refracted multiple times within the foam layer 2, thereby fully absorbing the vibration and reducing the vibration transmitted to external objects. The foam has good softness and elasticity for cushioning, while the rubber has good elasticity, wear resistance, and weather resistance, so the combined use of the rubber layer 1 and the foam layer 2 results in better shock absorption. Each foam layer 2 is fixed with a flame-retardant layer 3, each flame-retardant layer 3 is fixed with a substrate layer 4, and each substrate layer 4 is fixed with an adhesive layer 5. The flame-retardant layer 3 is made of flame-retardant polyester. When the power battery is bonded, the flame-retardant layer 3 can reduce the spread of fire in the event of an accidental fire. The substrate layer 4 is made of polytetrafluoroethylene, giving it good high-temperature resistance. The adhesive layer 5 is made of acrylic pressure-sensitive adhesive.

[0020] Working principle: This double-sided shockproof tape for power batteries uses two adhesive layers 5 to bond and fix the components of the power battery. When vibration occurs, the rubber layer 1 and the foam layer 2 deform to absorb the vibration. The foam layer 2 is connected to the rubber layer 1 through the plug block 202, which makes it easier for the foam layer 2 to deform left and right on the rubber layer 1, thus improving the deformation buffering capacity. The concave holes 201 provide a larger deformation space inside the foam layer 2. At the same time, the concave holes 201 can also hinder the propagation of vibration within the foam layer 2, change the direction of vibration transmission, and cause the vibration to be reflected and refracted multiple times within the foam layer 2, thereby fully absorbing the vibration and reducing the vibration transmitted to external objects.

[0021] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
