Description

Technical Field

[0001] The utility model relates to the field of thermal insulation pads, in particular to an aging-resistant thermal insulation pad. Background Art

[0002] With the development of social economy and the improvement of people's living standards, new energy vehicles have become a new means of transportation and are loved by many people. The market share of new energy vehicles is getting higher and higher. New energy vehicles have many advantages, such as saving fuel energy, reducing exhaust emissions, effectively protecting the environment, low noise, low operating costs, etc. For new energy vehicles, the safety of new energy modules (i.e. batteries) is very critical, and the market demand for the range of new energy vehicles is increasing. The capacity of new energy modules is also increasing, and the energy density is also increasing. Once thermal runaway occurs in new energy modules, it will be very dangerous.

[0003] The new energy module includes multiple battery modules. During the driving of the car, the battery cells in each battery module will be squeezed and rubbed against each other due to vibration, which may cause overheating, runaway or even fire. Therefore, thermal insulation pads need to be installed between adjacent battery cells.

[0004] The current thermal insulation pad generally has a structure in which a nano-composite plate is embedded in a buffer frame, and then two protective films are superimposed and set on the upper and lower surfaces of the buffer frame. Although the thermal insulation pad of this structure can basically achieve the thermal insulation function, the product is not resistant to aging, resulting in a short service life of the product. Moreover, the structure of the thermal insulation pad is simple. After a long time of use or when it is impacted by external force, the protective film is easy to loosen and open, causing the nano-composite plate to leak powder easily, reducing the thermal insulation performance of the product, affecting the quality of the product, and the service life of the product is short, which brings inconvenience to the user; and when making this thermal insulation pad, the buffer material must be cut to obtain the buffer frame. A lot of waste will be generated during the cutting process, wasting materials, and the production cost is high, which cannot meet the existing needs. Therefore, it is necessary to study a new technical solution to improve the current thermal insulation pad. Utility Model Content

[0005] In view of this, the utility model aims to solve the deficiencies in the prior art, and its main purpose is to provide an aging-resistant thermal insulation pad, which can effectively solve the problems of the existing thermal insulation pads, such as the lack of aging resistance, resulting in a short service life of the product. After a long period of use or when impacted by external force, the protective film is prone to loosening and opening, resulting in the nano-composite plate easily leaking powder, reducing the thermal insulation performance of the product, affecting the quality of the product, and shortening the service life of the product. During the production process, the buffer material must be cut to obtain the buffer frame, and a lot of waste will be generated in the cutting process, wasting materials and resulting in high production costs.

[0009] As a preferred solution, an upper hand-tear portion is provided on one side of the upper release film, which is convenient for tearing off the upper release film. The operation is simple, convenient and fast, which brings convenience to users.

[0010] As a preferred solution, the lower integrated protective film includes a lower PET film, a lower silicone adhesive layer, a lower double-sided adhesive layer and a lower release film which are stacked in sequence, and the lower PET film is stacked on the lower surface of the lower TPU film.

[0011] As a preferred solution, a lower hand-tear portion is provided on one side of the lower release film, which is convenient for tearing off the lower release film. The operation is simple, convenient and fast, bringing convenience to users.

[0012] As a preferred solution, the first 7-shaped buffer strip is made of silicone material, which has good high temperature resistance, corrosion resistance and buffering performance.

[0013] As a preferred solution, the second 7-shaped buffer strip is made of MPP material. The MPP material has strong impact resistance, good flexibility, and good high temperature resistance and buffering performance.

[0014] As a preferred solution, the installation cavity is square, and correspondingly, the nano-composite plate, the upper TPU film, the lower TPU film, the upper integrated protective film and the lower integrated protective film are all square.

[0015] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:
