Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite rugged mobile phone technology, specifically a composite rugged mobile phone screen anti-shatter edge frame. Background Technology
[0002] Rugged phones are highly protective devices, but all phones have screens, and screens are made of glass. Glass is easily broken when bumped or dropped. Therefore, rugged phones use an auxiliary frame to protect the phone and screen from damage from impacts and drops.
[0003] Existing composite rugged phone screen shatterproof edge frames use a hard-press snap-fit design, similar to the way existing phone cases are installed. The fixed frame structure is inconvenient for installation, while the spliced design makes the frame unstable enough, resulting in damage to the phone when dropped.
[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a composite tri-proof mobile phone screen shatterproof edge frame. Utility Model Content
[0005] The purpose of this invention is to provide a composite rugged mobile phone screen anti-shatter edge frame to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a composite tri-proof mobile phone screen shatterproof edge frame, including an upper frame, a lower frame snapped together on the lower side of the upper frame, a first protrusion fixedly connected to each of the four corners of the lower surface of the upper frame, and a second protrusion fixedly connected to each of the four corners of the upper surface of the lower frame for use in conjunction with the first protrusions. A spring plate is fixedly connected to the lower end of the first protrusion, and a protrusion is fixedly connected to the surface of the spring plate on the side away from the center of the upper frame. A slot is provided on the upper surface of each of the second protrusions. The upper frame and the lower frame form a detachable structure through the first and second protrusions.
[0007] Preferably, both the first and second protrusions are configured to match the arc shape of the phone's corner, and the position of the first protrusion on the upper frame corresponds to the position of the second protrusion on the lower frame.
[0008] Preferably, the protrusion is shaped as a horizontally placed trapezoid, with the inclined surface of the trapezoid facing the lower end of the first protrusion.
[0009] Preferably, the slot is shaped like an "L", and the protrusion combined with the spring plate also forms an "L" shape.
[0010] Preferably, the outer surfaces of both the upper and lower frames are fixedly connected with adhesive strips, and the upper surface of the lower frame is fixedly connected with soft rubber blocks on both the left and right sides.
[0011] Preferably, the coating strip is made of flexible silicone, and the soft rubber block is made of elastic rubber.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the arrangement of an upper frame, a lower frame, a first protrusion, a second protrusion, a spring plate, protrusions, and slots, connects the upper and lower frames via the first and second protrusions at their four corners. During connection, the spring plate, carrying the protrusions, inserts into the slot. The slot utilizes the inclined surface of the protrusions to push the spring plate to bend. When the protrusions align with the opening space of the slot, the spring plate uses its own elasticity to allow the protrusions to insert into the opening space of the slot, thereby connecting and fixing the first and second protrusions. The upper and lower frames form a complete covering frame, firmly covering the phone. In the event of drops or collisions, the upper and lower frames will provide protection. The combined frame makes contact with the point of impact, thus preventing the phone screen from shattering due to direct contact with the impact point, significantly improving the protection of the phone. When it is necessary to remove the phone, simply use the push tool to push the protrusion to squeeze the spring plate and bend it a second time, then the spring plate and the protrusion can be pulled out of the slot, separating the upper and lower frames, and the phone can be removed. The upper and lower frames combine to form a complete cover for the phone, providing full protection and effectively preventing shattering caused by drops or collisions. At the same time, the assembly and disassembly of the upper and lower frames are also very simple and convenient, improving the ease of use of the entire frame. 2. This utility model utilizes a covering strip and a soft rubber block. The covering strip is located on the outermost side of the frame, meaning it is the first to contact the point of impact. The elasticity of the covering strip can also buffer the impact, reduce damage, further improve the frame's protective effect, and enhance the comfort of manual grip. The soft rubber block is compressed after the upper and lower frames are joined and installed. The compression force causes the soft rubber block to expand to both sides and provides a pushing force up and down. The expanded soft rubber block can use the compression force to ensure the stability of the phone within the frame, and the resulting pushing force also makes the protrusion more firmly fasten to the side wall of the slot. This not only makes the phone more stable inside the frame but also reduces the gap between the upper and lower frames, preventing the frame itself from becoming loose due to redundant space in the frame assembly.

[0015] 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.
[0016] like Figures 1-3 As shown, a composite tri-proof mobile phone screen shatterproof edge frame includes an upper frame 1, a lower frame 2 that is snapped onto the lower side of the upper frame 1, a first protrusion 3 that is fixedly connected to each of the four corners of the lower surface of the upper frame 1, a second protrusion 4 that cooperates with the first protrusion 3 that is fixedly connected to each of the four corners of the upper surface of the lower frame 2, a spring plate 5 that is fixedly connected to the lower end of the first protrusion 3, a protrusion 6 that is fixedly connected to each of the surfaces of the spring plate 5 away from the center of the upper frame 1, and a slot 7 that is provided on the upper surface of each of the second protrusion 4. The upper frame 1 and the lower frame 2 form a detachable structure through the first protrusion 3 and the second protrusion 4. The first protrusion 3 and the second protrusion 4 are both set to be arc-shaped to match the corner of the mobile phone, and the position of the first protrusion 3 on the upper frame 1 corresponds to the position of the second protrusion 4 on the lower frame 2; the shape of the protrusion 6 is set to be a horizontally placed trapezoid, and the slope of the trapezoid faces the lower end of the first protrusion 3; the shape of the slot 7 is set to be "L"-shaped, and the protrusion 6 and the spring plate 5 also form an "L" shape.
[0017] By adopting the above technical solution, the upper frame 1 and the lower frame 2 are connected by the first protrusion 3 and the second protrusion 4 at the four corners; During docking, the spring plate 5 carrying the protrusion 6 is inserted into the slot 7. The slot 7 uses the inclined surface of the protrusion 6 to push the spring plate 5 to bend. When the protrusion 6 is aligned with the opening space of the slot 7, the spring plate 5 will use its own elasticity to make the protrusion 6 insert into the opening space of the slot 7, thereby connecting and fixing the first protrusion 3 and the second protrusion 4. The upper frame 1 and the lower frame 2 form a complete covering frame to firmly cover the mobile phone. In the event of a drop or impact, the protective frame formed by the combination of the upper frame 1 and the lower frame 2 will come into contact with the point of impact, thereby preventing the point of impact from directly contacting the phone and causing the phone screen to shatter, thus greatly improving the protection of the phone. When it is necessary to remove the phone, simply use the pusher tool to push the protrusion 6 to squeeze the spring plate 5 and bend it twice. Then the spring plate 5 and the protrusion 6 can be pulled out of the slot 7, separating the upper frame 1 and the lower frame 2, and the phone can be removed.
[0018] Furthermore, the outer surfaces of both the upper frame 1 and the lower frame 2 are fixedly connected with adhesive strips 8, and the upper surface of the lower frame 2 is fixedly connected with soft rubber blocks 9 on both the left and right sides; the adhesive strips 8 are made of flexible silicone, and the soft rubber blocks 9 are made of elastic rubber.
[0019] By adopting the above technical solution, the covering strip 8 is located on the outermost side of the frame, that is, the covering strip 8 is in priority contact with the collision point. The elastic force of the covering strip 8 can also buffer the impact of the collision and reduce the damage. After the soft rubber block 9 is installed by the mating of the upper frame 1 and the lower frame 2, it will be squeezed. The squeezing force causes the soft rubber block 9 to expand to both sides and provides the force to push up and down. The extended soft rubber block 9 can use the squeezing force to ensure the stability of the phone within the frame, and the resulting up-and-down pushing force also makes the protrusion 6 more firmly hold the side wall of the slot 7. This not only makes the phone more stable inside the frame, but also reduces the gap between the upper frame 1 and the lower frame 2, avoiding the frame itself from becoming loose due to the redundant space in the frame assembly.
[0020] Working Principle: When using this composite rugged phone screen shatterproof edge frame, firstly, place the phone inside the lower frame 2, then cover it with the upper frame 1. The upper frame 1 and lower frame 2 are joined by the first protrusion 3 and the second protrusion 4 at the four corners. During the joining, the spring plate 5 carrying the protrusion 6 inserts into the slot 7. The slot 7 uses the inclined surface of the protrusion 6 to push the spring plate 5 to bend. When the protrusion 6 aligns with the opening space of the slot 7, the spring plate 5 will use its own elasticity to make the protrusion 6 insert into the opening space of the slot 7, thereby connecting and fixing the first protrusion 3 and the second protrusion 4. The upper frame 1 and the lower frame 2 form a complete covering frame, firmly covering the phone. The soft rubber block 9 will be squeezed after the upper frame 1 and the lower frame 2 are joined and installed. The squeezing force causes the soft rubber block 9 to expand to both sides and provide a pushing force up and down. The expanded soft rubber block 9 can use the squeezing force to ensure the stability of the phone within the frame, and the generated pushing force also makes the protrusion 6 more firmly fasten to the side wall of the slot 7, thus not only This design makes the phone more stable inside the frame and reduces the gap between the upper frame 1 and the lower frame 2, preventing the frame from becoming loose due to redundant space in the assembly. When the phone is dropped or bumped, the protective frame formed by the upper frame 1 and the lower frame 2 will contact the point of impact, thus preventing the phone screen from shattering due to direct contact with the impact point. This significantly improves the protection of the phone. The protective strip 8 is located on the outermost side of the frame, meaning it is the first to contact the point of impact. The elasticity of the protective strip 8 can also buffer the impact, reducing damage and further improving the frame's protective effect. It also improves the comfort of holding the phone. When it is necessary to remove the phone, simply use a pushing tool to push the protrusion 6 to squeeze the spring plate 5 and bend it twice. Then, the spring plate 5 and the protrusion 6 can be pulled out of the slot 7, separating the upper frame 1 and the lower frame 2, and the phone can be removed. This is the working principle of this composite tri-proof phone screen shatterproof edge frame.
