Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone screen assemblies, in particular to a mobile phone screen assembly with a corner protection structure. Background Art

[0002] A mobile phone's screen assembly refers to the combination of the touchscreen and display, and typically includes the housing and other related components. It's the most crucial part of a phone, directly impacting the user experience and visual quality.

[0003] my country's public patent, application number CN202223289226.7, mentions a mobile phone screen assembly with a side protection structure: "A total body, wherein the four sides of the total body are fixed with frames, one side outer wall of the frame is connected to a connecting cable, and one end outer wall of the frame is surrounded by a frame; a holder, which is fixed to the outer wall of the frame at one end close to the frame, and a support rod is arranged on the inner side of the holder, and the support rod is provided with a perforation inside, and the perforation extends to the outer walls at both ends of the support rod. The mobile phone screen assembly with a side protection structure is provided with a frame and a support rod buckled on the inner side of the holder, which is used to provide anti-bending protection when the side of the total body is subjected to force. The frame improves the structural stability of the frame through a straight edge structure, and the support rod is engaged with the holder through blocks on both sides of the frame, so that when the frame is bent, the stability of both sides of the frame can be maintained by its own structure, thereby reducing the probability of the frame breaking when the side is subjected to force."

[0004] In the patents retrieved above, an anti-bending protection structure is provided on the frame to prevent the frame from breaking when subjected to force. Although this method can achieve the claimed effect, we found in actual simulation use that this technology still has certain defects:

[0005] Current technology only provides an anti-bending protection structure on the frame. However, during daily use of a mobile phone, if it is not handled carefully and the phone is dropped from a height, when the corners of the phone first collide with the ground, the impact force will act on the screen assembly, causing the components in the screen assembly to loosen or even be damaged, greatly increasing the probability of the screen assembly being damaged and malfunctioning. Therefore, to avoid the problem of the screen assembly being damaged due to the corners of the phone colliding with the ground when the phone is dropped, we have designed a mobile phone screen assembly with a corner protection structure. Utility Model Content

[0006] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a mobile phone screen assembly with a corner protection structure, comprising a front shell, a display inner screen installed in the middle of the inner wall of the front shell, and a touch outer screen installed on the outside of the front shell and at a position corresponding to the display inner screen; corners are provided at the four corners of the front shell, and buffer zones are provided at the four inner corners of the front shell and at positions close to each corner, a fixing column is fixed on the inner bottom wall of each buffer zone, and two groups of buffer components are fixed on the side of the fixing column close to the corner; the buffer component includes a fixing cylinder fixed on the fixing column and a buffer column movably sleeved in the fixing cylinder, one end of the buffer column placed in the fixing cylinder is connected to a buffer spring, and the end of the buffer column away from the fixing cylinder is fixed to a buffer plate.

[0008] As a further solution of the present invention: the two buffer columns on each group of the buffer components are fixed on a buffer plate, and the buffer plate is attached to the inner wall of the corner.

[0009] As a further solution of the present invention: the buffer plate is designed to be arc-shaped and fits tightly with the inner wall of the corner, and the buffer plate is made of a hard steel sheet.

[0010] As a further solution of the present invention: a sliding disk is fixed to one end of the buffer column extending into the fixed cylinder, a positioning rod is fixed to one side of the sliding disk, and the sliding disk is slidably connected to the buffer cavity opened in the inner cavity of the fixed cylinder.

[0011] As a further solution of the present invention: the buffer spring is placed in the buffer cavity, one end of the buffer spring is sleeved on the positioning rod and contacts the sliding disk, and the other end of the buffer spring is fixed on the inner wall of the buffer cavity.

[0012] As a further solution of the present invention: different types of components are also installed inside the front shell, some of the components are located above the buffer zone and cover the buffer assembly, and the rear shell is buckled on the front shell.

[0013] As a further solution of the present invention: a locking screw hole is provided on the top of each of the fixing columns, and the locking screw hole is used to lock the components located above the buffer zone.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] In the present application, a buffer zone is formed in the blank space at the four corners inside the front shell, and structures such as a buffer assembly and a buffer plate are arranged in the buffer zone, so that a buffer structure can be formed at the corners. When the mobile phone falls from a high place and hits the ground at the corners, the buffer assembly can play a good buffering and shock-absorbing effect, thereby reducing the impact force on the display screen and components set inside the front shell, reducing the possibility of damage, and thus the entire mobile phone screen assembly is well protected. This design scheme has a simple structure and occupies a small area. It does not require a separate area for the buffer assembly to be installed. That is, the buffer assembly of the present application is installed in the blank area at the four corners of the front shell, which can avoid occupying the internal space and does not affect the installation of other components, thereby ensuring that the utilization of the internal space of the front shell is maximized.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4, a mobile phone screen assembly with a corner protection structure, including a front shell 1, a display inner screen 101 is installed in the middle of the inner wall of the front shell 1, and a touch outer screen is installed on the outside of the front shell 1 and at a position corresponding to the display inner screen 101; corners 4 are provided at the four corners of the front shell 1, and buffer zones 5 are provided at the four inner corners of the front shell 1 and near each corner 4, and a fixing column 6 is fixed on the inner bottom wall of each buffer zone 5, and two groups of buffer components 7 are fixed on the side of the fixing column 6 close to the corner 4; the buffer component 7 includes a fixing cylinder 701 fixed on the fixing column 6 and a buffer column 702 movably sleeved in the fixing cylinder 701, one end of the buffer column 702 placed in the fixing cylinder 701 is connected to a buffer spring 10, and the end of the buffer column 702 away from the fixing cylinder 701 is fixed to a buffer plate 8.

[0024] See also Figure 2-4 In this embodiment, the two buffer columns 702 on each group of buffer components 7 are fixed on a buffer plate 8, and the buffer plate 8 is attached to the inner wall of the corner 4; the buffer plate 8 is designed to be an arc shape and fits tightly with the inner wall of the corner 4, and the buffer plate 8 is made of a hard steel sheet.

[0025] Specifically, the buffer plate 8 can serve as a medium between external impact force and buffering force. When the corner 4 is hit and generates impact force, it will first act on the buffer plate 8 and be transmitted to the buffer component 7 through the buffer plate 8. Finally, the buffer component 7 is used to buffer the impact force, thereby reducing the damage to the display inner screen 101 and other components. The buffer plate 8 is arc-shaped and made of steel sheet. Its function is to better fit the inner wall of the corner 4 and have a certain hardness to enhance strength.

[0026] See also Figure 4 In this embodiment, a sliding disk 11 is fixed to one end of the buffer column 702 extending into the fixed cylinder 701, and a positioning rod 12 is fixed to one side of the sliding disk 11. The sliding disk 11 is slidably connected to the buffer cavity 9 opened in the inner cavity of the fixed cylinder 701; a buffer spring 10 is placed in the buffer cavity 9, one end of the buffer spring 10 is sleeved on the positioning rod 12 and contacts the sliding disk 11, and the other end of the buffer spring 10 is fixed to the inner wall of the buffer cavity 9.

[0027] Specifically, when the buffer column 702 is impacted, it will slide in the buffer cavity 9 through the sliding plate 11 and gradually compress the buffer spring 10, thereby utilizing the deformation of the buffer spring 10 to buffer the impact force, thereby reducing damage to the screen assembly.

[0028] See also Figure 1-3In this embodiment, different types of components 3 are also installed inside the front shell 1. Some components 3 are located above the buffer zone 5 and covered on the buffer assembly 7. The rear shell 2 is buckled onto the front shell 1. A locking screw hole 601 is provided at the top of each fixing column 6. The locking screw hole 601 is used to lock the components 3 located above the buffer zone 5.

[0029] Specifically, the installation position of component 3 does not conflict with the buffer assembly 7 in the buffer zone 5, the installation positions do not affect each other, do not occupy the space required for the installation of component 3, do not affect the installation of all components 3, and component 3 covers the top of the buffer zone 5, and a locking screw hole 601 is opened on the fixing column 6, which can provide convenience for the fastening of component 3 without the need for drilling holes.

[0030] When a mobile phone assembled by the present mobile phone screen assembly is in use, if it falls from a height, when any corner 4 of the front shell 1 hits the ground, the impact force will first act on the buffer plate 8, and the buffer plate 8 transfers the force to the buffer column 702. The buffer column 702 is forced to push the buffer spring 10, and the buffer spring 10 is deformed to absorb the impact force, thereby buffering the impact force. That is to say, when the corner 4 of the front shell 1 hits the ground, since the buffer component 7 is provided at the corner 4, the impact force can be greatly reduced by the buffering effect of the buffer component 7, thereby reducing the possibility of damage to the display inner screen 101 or other components caused by the impact of the corner 4 when the mobile phone falls.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
