Description

Technical Field

[0001] This utility model relates to the field of tempered glass film technology, specifically to a buffering and shock-absorbing protective tempered glass film. Background Technology

[0002] With the widespread use of electronic devices, tempered glass screen protectors, as an important screen protection accessory, have been widely used in the market. Traditional tempered glass screen protectors are designed to protect the screens of electronic devices from everyday damage such as scratches and abrasions.

[0003] However, in actual use, electronic devices often encounter accidental drops and collisions. In such cases, traditional tempered glass screen protectors often fail to provide sufficient impact protection. When a device is impacted, the impact force is concentrated on the weak points such as the edges and corners of the tempered glass screen protector, which can easily cause it to crack. Consequently, it cannot effectively protect the screen, leading to problems such as screen breakage and damage, resulting in economic losses and inconvenience for users.

[0004] To address this issue, some measures have emerged in the market that attempt to improve shock resistance, such as increasing the thickness of tempered glass screen protectors, but this can affect the device's portability and touch sensitivity; or using thicker cushioning material, but this may lead to a deterioration in screen display quality.

[0005] Therefore, it is necessary to propose new solutions to address the aforementioned problems. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0007] A shock-absorbing and protective tempered glass film includes a tempered glass film body;

[0008] The tempered glass film body has protrusions connected to each of its four corners;

[0009] The tempered glass film body is surrounded by protective edge strips;

[0010] The protrusions and the protective strips are connected to each other at the edge of the tempered glass film body.

[0011] As a further embodiment of this utility model: the protrusion extends to form a connecting part on the side near the protective edge strip, and the protective edge strip has a connecting groove on the side near the protrusion, and the connecting part is embedded in the connecting groove.

[0013] The protrusion is tightly attached to the surface of the tempered film body through the second adhesive layer, and the gaps between the second adhesive layer and the protective edge strip at the connection part and the insertion point of the connecting groove are filled and bonded.

[0014] As a further embodiment of this utility model: both the first adhesive layer and the second adhesive layer are optically transparent adhesives.

[0015] As a further embodiment of this utility model: the protrusion extends beyond the height of the protective edge strip in the height direction.

[0016] As a further embodiment of this utility model: the surface of the protrusion is provided with an anti-slip texture, which is a grid or stripe pattern.

[0017] As a further embodiment of this utility model: the connecting part is interference-fitted with the connecting groove, and micro-protrusion structures are provided on the surface of the connecting part and the inner wall of the connecting groove. The micro-protrusion structures are irregular in shape. During the process of the connecting part being embedded into the connecting groove, the micro-protrusion structures come into contact with each other and undergo extrusion deformation.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The design of bumps and protective strips effectively disperses impact force, reducing the likelihood of the tempered glass screen protector cracking at the edges and corners due to concentrated force.

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-2 In this embodiment of the present invention, a buffering and shock-absorbing protective tempered glass film includes a tempered glass film body 1;

[0028] The tempered glass film body 1 has protrusions 2 connected to each of its four corners;

[0029] The tempered glass film body 1 is surrounded by protective edge strips 3;

[0030] The protrusion 2 and the protective strip 3 are connected to each other at the edge of the tempered film body 1.

[0031] The protrusions 2 are set at the four corners of the surface of the tempered glass screen protector 1. This is based on the characteristic that when electronic devices are accidentally dropped or collided, the impact force is often concentrated on the weak parts such as the edges and corners. When impacted, the protrusions 2 can first contact the external object and disperse the impact force to the protrusions 2, so as to avoid the impact force being directly concentrated on the weak corners of the tempered glass screen protector, thereby reducing the possibility of the tempered glass screen protector breaking due to concentrated force at the corners.

[0032] A protective edge strip 3 is connected around the edge of the tempered glass film body 1. The protective edge strip 3 can buffer and disperse the impact force when the equipment is impacted. It can absorb and disperse the impact force acting on the edge of the tempered glass film to a certain extent, so that the impact force will not be too concentrated on the edge of the tempered glass film, reducing the risk of edge breakage.

[0033] The protrusion 2 and the protective edge strip 3 are connected to each other at the edge of the tempered film body 1, forming a continuous impact-resistant structure. This enhances the impact resistance of the entire edge area of ​​the tempered film. When impacted, the impact force can be better transmitted and dispersed between the protrusion 2 and the protective edge strip 3, further improving the protection effect of the tempered film body 1 and enabling it to more effectively cope with various accidental impact situations.

[0034] In summary, the design of bump 2 and protective edge strip 3 effectively disperses the impact force, reducing the likelihood of the tempered glass screen protector cracking at the edges and corners due to concentrated force. This significantly improves the impact resistance of the tempered glass screen protector, thereby better protecting the screen of electronic devices, reducing the probability of the screen breaking or being damaged due to impact, and minimizing the user's economic losses. Compared to traditional improvement measures such as increasing the thickness of the tempered glass screen protector or using thicker buffer layer materials, this design does not affect the device's slimness and portability, as the design of bump 2 and protective edge strip 3 does not significantly increase the overall thickness. At the same time, it does not adversely affect the touch sensitivity of the device, ensuring a normal user experience.

[0035] In this embodiment of the present invention, the protrusion 2 extends to form a connecting portion 4 on the side near the protective edge strip 3, and the protective edge strip 3 is provided with a connecting groove 5 on the side near the protrusion 2, and the connecting portion 4 is embedded in the connecting groove 5.

[0036] The connecting part 4 on the protrusion 2 is embedded in the connecting groove 5 of the protective edge strip 3, forming an embedded connection structure. This design makes the connection between the protrusion 2 and the protective edge strip 3 tighter and more stable, and can work together better to resist impact. When subjected to impact, the cooperation between the connecting part 4 and the connecting groove 5 can effectively prevent relative displacement or separation between the protrusion 2 and the protective edge strip 3, ensuring the integrity of the entire impact-resistant structure.

[0037] In this embodiment of the present invention, the protective edge strip 3 is tightly attached to the edge of the tempered film body 1 through the first adhesive layer;

[0038] The protrusion 2 is tightly attached to the surface of the tempered film body 1 through the second adhesive layer, and is filled and bonded to the protective strip 3 at the joint 4 and the joint groove 5 through the second adhesive layer.

[0039] The protective edge strip 3 is tightly attached to the edge of the tempered glass film body 1 through the first adhesive layer, and the protrusion 2 is tightly attached to the surface of the tempered glass film body 1 through the second adhesive layer. The first and second adhesive layers can firmly fix the protective edge strip 3 and the protrusion 2 to the tempered glass film body 1 respectively, preventing them from falling off during use. At the same time, the second adhesive layer is also used to fill the gaps at the joint 4 and the joint groove 5, further enhancing the tightness of the connection between the protrusion 2 and the protective edge strip 3, avoiding stress concentration or water / dust ingress caused by gaps. Furthermore, the use of the first and second adhesive layers enables the protective edge strip 3, the protrusion 2, and the tempered glass film body 1 to form a tight integral structure. When subjected to external impact, this tight connection helps to better transmit and disperse the impact force, allowing the entire tempered glass film to jointly withstand the external force, thereby improving the stability and impact resistance of the structure.

[0040] In this embodiment of the invention, both the first adhesive layer and the second adhesive layer are optically transparent adhesives.

[0041] Optical transparent adhesive has the characteristics of high light transmittance and low haze, which can match the optical performance of the tempered glass screen protector 1 and the screen of electronic devices. Using this adhesive as the first and second adhesive layers can ensure that light refraction, reflection and scattering are minimized when passing through the tempered glass screen protector, ensuring the clarity and color reproduction of the screen display, so that users will not feel a visual difference due to the presence of the first and second adhesive layers when using electronic devices. The optical transparent adhesive also has good adhesion performance. For the connection between the protective strip 3, the protrusion 2 and the tempered glass screen protector 1, it can provide reliable adhesion force to ensure that there will be no delamination during long-term use and maintain the stability of the entire impact-resistant structure.

[0042] In this embodiment of the present invention, the connecting part 4 is interference-fitted with the connecting groove 5, and micro-protrusion structures 7 are provided on the surface of the connecting part 4 and the inner wall of the connecting groove 5. The micro-protrusion structures 7 are irregular in shape. During the process of the connecting part 4 being embedded into the connecting groove 5, the micro-protrusion structures 7 come into contact with each other and are subjected to extrusion deformation.

[0043] An interference fit means that the size of the connecting part 4 is slightly larger than the size of the connecting groove 5. During installation, a certain external force needs to be applied to make the connecting part 4 embed into the connecting groove 5. This fit can generate greater friction and extrusion between the connecting part 4 and the connecting groove 5, thereby enhancing the connection strength between the protrusion 2 and the protective edge strip 3, ensuring that they can be tightly joined together to resist external forces when subjected to impact.

[0044] Irregular micro-protrusion structures 7 are provided on the surface of the connecting part 4 and the inner wall of the connecting groove 5. When the connecting part 4 is embedded in the connecting groove 5, these micro-protrusion structures 7 come into contact with each other and generate extrusion deformation. On the one hand, the irregular micro-protrusion structures 7 increase the contact area and roughness between the connecting part 4 and the connecting groove 5, thereby further increasing the friction and making the connection more stable. On the other hand, the extrusion deformation of the micro-protrusion structures 7 can absorb some of the impact force and play a buffering role. Just like a tiny spring, it can reduce the transmission of impact force through its own deformation when subjected to external force, thereby improving the impact resistance of the entire structure.

[0045] Furthermore, the second adhesive layer fills the gaps, making the connection between the connecting part 4 and the connecting groove 5 tighter, and also providing a sealing effect to a certain extent, preventing external factors from eroding and damaging the connecting part 4, thus further enhancing the stability of the structure.

[0046] In this embodiment of the present invention, the protrusion 2 extends beyond the height of the protective strip 3 in the height direction.

[0047] The edges of electronic device screens are the most vulnerable to bumps and impacts. By designing the protrusion 2 to extend beyond the protective strip 3 in the height direction, when the device edge is hit, the protrusion 2 can first contact the external object, playing a role in buffering and dispersing the impact force, preventing the impact force from acting directly on the screen edge, thus providing more comprehensive and effective protection for the screen.

[0048] Specifically, it can be designed that the height of the protrusion 2 is greater than the height of the protective rubber strip, and the thickness of its connecting part 4 is adapted to the depth of the connecting groove 5, that is, the height of the connecting part 4 is the same as the height of the protective rubber strip.

[0049] In this embodiment of the present invention, the surface of the protrusion 2 is provided with an anti-slip texture 6, which is a grid or stripe pattern.

[0050] The grid-like or striped anti-slip texture 6 can disrupt the smoothness of the surface of the bump 2, increasing the number of contact points and making them more evenly distributed when the surface comes into contact with other objects; when an external force attempts to make an object slide on the surface of the bump 2, these textures will hinder the object's sliding and achieve the purpose of anti-slip by increasing friction.

[0051] The presence of texture changes the tactile feel of the bump 2 surface. When a user touches or operates an electronic device, their finger contacts the surface of the bump 2, and the anti-slip texture 6 provides clearer tactile feedback, allowing the user to more clearly perceive the contact state between their finger and the edge of the screen, which helps to improve the accuracy and comfort of operation.

[0052] Preferably, the bump 2 is located at the corner of the phone, which is the edge area of ​​the screen. When people view the content of the phone, their attention is usually focused on the center of the screen and the main display area. The bump 2 at the corner is at the visual edge and is not easily noticed. As long as the size of the bump 2 is designed reasonably and does not extend too far beyond the screen border, it will not cause much interference to the normal viewing angle.

[0053] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
