[0001] The utility model relates to the field of mylar, especially an anti-impact mylar. BACKGROUND

[0002] Mylar is a kind of PET polyester film formed by heating dimethyl terephthalate and ethylene glycol with the aid of related catalyst, ester exchange and vacuum polycondensation, biaxial stretching. It is widely used in electrical insulation industry, suitable for electronics, mobile phones, displays, computers and peripheral equipment, and plays a protective role.

When the mylar is attached to the corresponding device, the glue layer is attached to the surface of the device to be attached, and the attachment of the mylar is completed. When the mylar is attached to the electronic component, the damage of the electronic component may be caused by the collision of foreign matter, and the mylar cannot play the role of buffering. UTILITY MODEL CONTENT

[0006] Compared with the prior art, when external pressure acts on the lower layer, the pressure is transmitted to the shock absorber through the lower layer, the shock absorber deforms under the action of the pressure and generates a counterforce in the opposite direction of the pressure.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application.

[0023] Embodiment one, as Figures 1-3As shown, the Mylar sheet of the utility model, including base layer 01, glue layer 02 and release paper 03, glue layer 02 is located between base layer 01 and release paper 03, in use, release paper 03 is peeled from glue layer 02, then glue layer 02 is aligned with the surface of the electronic component to be attached, and the attachment of Mylar sheet is completed. Base layer 01 includes upper layer 04 and lower layer 05, shock-absorbing body 06 is arranged between upper layer 04 and lower layer 05, and the two ends of shock-absorbing body 06 are fixedly connected to upper layer 04 or lower layer 05 as a whole by one-piece forming or hot melt welding. Glue layer 02 is fixedly connected with upper layer 04. When pressure is applied on upper layer 04 or lower layer 05, when the pressure is transmitted to shock-absorbing body 06, shock-absorbing body 06 deforms under the action of pressure and generates a force in the opposite direction of the pressure. The reaction force and the pressure are offset. Thus the purpose of buffering is achieved, and the direct action of the forward pressure on the electronic component is avoided, thereby achieving the protection purpose of the electronic component.

[0024] As Figures 2-3 shown, in the embodiment, shock-absorbing body 06 is a solid body and is in a spiral shape, shock-absorbing body 06 has upper end face 07 and lower end face 08, and upper end face 07 and lower end face 08 are connected by spiral side face 09. Thus the whole shock-absorbing body 06 is twisted in a spiral shape. Side face 09 can be twisted in a clockwise spiral or a counterclockwise spiral.

[0025] Upper end face 07 and lower end face 08 are arranged in a staggered manner, that is, upper end face 07 and lower end face 08 are arranged at an included angle R, and the included angle R is zero to ninety degrees. Upper end face 07 and lower end face 08 are both polygons with the same number of sides, and side face 09 with the same number of sides as the polygon is arranged between upper end face 07 and lower end face 08.

[0026] For example, a forward pressure (external impact force) is applied on lower end face 08, and in the process of downward transmission of the forward pressure (in the process of transmission to upper end face 07), the forward pressure is transmitted to lower end face 08 along side face 09, and since side face 09 is in a spiral shape, when lower end face 08 moves in the direction of upper end face 07 under the action of the forward pressure, since upper end face 07 and lower end face 08 are connected by spiral side face 09, a force in the opposite direction of the forward pressure is generated in side face 09 in the process of extrusion to offset the forward pressure. Therefore, the impact force cannot pass through base layer 01 to act on the electronic component, and the protection of the electronic component is achieved.

[0027] When several shock-absorbing bodies 06 are arranged between upper layer 04 and lower layer 05, the Mylar sheet has the ability to resist impact. During assembly, upper end face 07 and upper layer 04 are fixedly connected by one-piece forming, hot melt welding or adhesive bonding. Lower end face 08 and lower layer 05 are fixedly connected by the same connection method.

[0028] Example 2, as Figures 4-5 As shown, the shock absorber 06 in this embodiment acts on the left extension body 10 and the right extension body 11. The upper buffer body 12 and the lower buffer body 13 are integrally formed between the left extension body 10 and the right extension body 11, giving the shock absorber 06 an elliptical shape. A buffer zone 14 is provided between the upper buffer body 12 and the lower buffer body 13, giving the shock absorber 06 a hollow structure.

[0029] When positive pressure is applied to the lower buffer body 13, as the lower buffer body 13 moves into the buffer zone 14 (toward the upper buffer body 12), a reverse elastic force is generated during the movement of the lower buffer body 13 into the buffer zone 14, which offsets the positive pressure acting on the lower buffer body 13. This ensures that the positive pressure is not transmitted to the upper buffer body 12, and the electronic components located on the side of the upper buffer body 12 are not affected by the positive pressure.

[0030] The upper buffer body 12 and the lower buffer body 13 are both arc-shaped, and the upper buffer body 12 and the lower buffer body 13 are in opposite directions. The arc-shaped arrangement allows the upper buffer body 12 or the lower buffer body 13 to generate a force opposite to the external pressure when it moves toward the buffer zone 14 after being subjected to external pressure to offset the external pressure.

[0031] When multiple shock absorbers 06 are positioned between the upper layer 04 and the lower layer 05, gaps 15 are provided between adjacent shock absorbers 06. However, when shock absorbers 06 are subjected to external pressure, the left and right extensions 10, 11 may deform to the sides. The provision of gaps 15 provides ample room for deformation for the left and right extensions 10, 11, preventing interference between the two shock absorbers 06 and affecting the shock absorption effect.

[0032] Therefore, several shock absorbers 06 are evenly distributed between the upper layer 04 and the lower layer 05, with gaps between adjacent shock absorbers 06. The shock absorbers 06 and the base layer 01 are injection molded from the same material. During use, when external pressure acts on the lower layer 05, the pressure is transmitted to the shock absorbers 06 through the lower layer 05. The shock absorbers 06 deform under the pressure and generate a reaction force in the opposite direction of the pressure. This reaction force offsets the pressure, achieving the purpose of cushioning. The gaps also provide ample room for deformation of the shock absorbers 06 during this process.

[0033] If the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0034] The above embodiments only describe the preferred embodiments of the utility model, and do not limit the scope of the utility model, and various deformations and improvements of the technical scheme of the utility model made by the ordinary engineering technicians in the art without departing from the design spirit of the utility model shall fall within the protection scope determined by the claims of the utility model.
