Description

A mounting structure for outer and inner screens of a mobile phone display screen

Technical Field

The present invention belongs to the technical field of screen installation structures, and in particular, relates to an installation structure for an outer screen and an inner screen of a mobile phone display screen.

Background technique

Mobile phone, whose full name is mobile phone or wireless phone, is commonly called mobile phone. It was originally just a communication tool. In the early days, it was also commonly known as "big brother". It is a portable telephone terminal that can be used in a wide range. Mobile phones are divided into smart phones and non-smart phones. Generally, the performance of smart phones is better than that of non-smart phones, but the performance of non-smart phones is more stable than that of smart phones.

At present, the mobile phone display screen is a very important component for smart phones. The mobile phone display screen is generally divided into an inner screen and an outer screen during manufacturing. The outer screen generally serves as a protective shell for the inner screen. However, when connecting the inner screen and the outer screen, most of them are installed by dispensing glue. Once this installation method is damaged and needs to be repaired and disassembled, it is more difficult, therefore, it is not convenient to carry out maintenance work.

Summary of the invention

In response to the problems of the existing mobile phone screen mounting structure, the present invention provides a mounting structure for an outer screen and an inner screen of a mobile phone display screen. The mounting mechanism drives two connecting rods to move relative to each other through gears, so that the interlocking columns used for fixing can be inserted into the fixing holes of the inner screen to realize the connection between the inner and outer screens, thereby solving the shortcoming of traditional glue point connection that makes it inconvenient to disassemble for later maintenance from the installation method.

To solve the above problems, the present invention adopts the following technical solutions.

A mounting structure for an outer screen and an inner screen of a mobile phone display screen comprises an inner screen and an outer screen, wherein a groove for the inner screen to be embedded is provided at the bottom of the outer screen, fixing mechanisms are provided inside the front and rear ends of the outer screen, and fixing holes connected to the fixing mechanisms are provided at both ends of the side surfaces of the inner screen.

Preferably, the fixing mechanism includes a gear and a first connecting rod and a second connecting rod arranged at the upper and lower ends of the gear, the bottom tail end of the first connecting rod and the top front end of the second connecting rod are both integrally formed with racks, and the first connecting rod is meshed with the top of the gear through the rack, and the second connecting rod is meshed with the bottom of the gear through the rack.

Preferably, the end of the first connecting rod is vertically connected to the first sub-rod, and the end of the second connecting rod is vertically connected to the second sub-rod, and the bottoms of the first sub-rod and the second sub-rod are on the same horizontal line.

Preferably, the length of the first sub-rod is the sum of the length of the second sub-rod and the gear diameter, and an interlocking column is connected to the opposite side of the lower ends of the first sub-rod and the second sub-rod, and the length of the interlocking column is the same as the depth of the fixing hole, and the width of the interlocking column is equal to the diameter of the fixing hole.

Preferably, a short shaft is fixedly connected at the center of the front end of the gear, and the short shaft passes through the side wall of the outer screen. The end of the short shaft is fixedly connected to a fixing plate at a position deviating from the center of the circle, and a screw hole is provided on the fixing plate. A screw groove is provided at the corresponding position of the outer wall of the outer screen.

Preferably, a protective pad is attached to the bottom edge of the outer screen, and the width of the protective pad is half of the width of the bottom edge of the outer screen.

Preferably, a sliding groove is provided in the middle of the first connecting rod and the second connecting rod, and the ends of the first connecting rod and the second connecting rod are pin-connected with a limiting rod, and the limiting rod is slidably connected in the sliding groove.

Beneficial Effects

Compared with the prior art, the present invention has the following beneficial effects:

(1) In the present invention, the outer screen and the inner screen are fixedly connected by a fixing mechanism, so that the inner screen and the outer screen can be installed without using glue, and the installation operation is simple, convenient and stable. It is also convenient when disassembly and maintenance are required. The specific process is as follows: fixing holes are provided on both sides of the inner screen for fixing. The inner and outer screens are assembled by connecting the fixing mechanism and the fixing holes on the outer screen. The fixing mechanism is composed of a first connecting rod, a second connecting rod and a gear. The first connecting rod and the second connecting rod are relatively moved by the rotation of the gear. The first connecting rod and the second connecting rod are connected with a mating column through a secondary rod. The inner and outer screens are assembled by plugging the mating column into the fixing hole.

(2) In the present invention, a fixing mechanism is constrained by the fixing plate and the screw hole, so that the gears in the fixing mechanism can be prevented from reversing, so that the first connecting rod and the second connecting rod cannot maintain the preset state, causing the inner screen and the outer screen to be separated due to loose connection. The use process is as follows: a hole is also opened on the outer screen. When the gear of the fixing mechanism rotates to drive the first connecting rod and the second connecting rod to move relative to each other, the interlocking column is first retracted to make room for the inner screen to fit the outer screen. When the inner and outer screens are fitted together, the gear is rotated counterclockwise to make the first connecting rod and the second connecting rod drive the interlocking column to extend and plug into the fixing hole. Finally, the screw hole on the fixing plate is aligned with the hole on the outer screen and connected with screws, thereby finally realizing the constraint of the fixing mechanism.

(3) In the present invention, by providing a protective pad, the tightness of the installation between the inner screen and the outer screen can be increased during installation, which can not only effectively reduce the intrusion of dust, but also has a certain buffering and shock-absorbing effect.

Detailed ways

The present invention is further described below in conjunction with specific inventions.

In Figures 1, 2 and 3, a mounting structure for an outer screen and an inner screen of a mobile phone display screen is shown, including an inner screen 1 and an outer screen 3. The inner screen 1 and the outer screen 3 together form a complete mobile phone screen. A groove is provided at the bottom of the outer screen 3 for the inner screen 1 to be embedded in. The length and width of the groove are equal to the length and width of the inner screen 1, and the depth of the groove is equal to the thickness of the inner screen 1. The outer screen 3 is covered on the inner screen 1 through the groove, and fixing mechanisms 16 are provided inside the front and rear ends of the outer screen 3. When the outer screen 3 covers the inner screen 1, the inner screen 1 is constrained by the fixing mechanisms, thereby ensuring the connection stability between the inner screen 1 and the outer screen 3. Fixing holes 4 connected to the fixing mechanisms 16 are provided at both ends of the side surfaces of the inner screen 1. The fixing holes 4 are opened for connection with the fixing mechanisms 16.

In Figure 3, the fixing mechanism 16 includes a gear 13 and a first connecting rod 7 and a second connecting rod 10 arranged at the upper and lower ends of the gear 13. The bottom tail end of the first connecting rod 7 and the top front end of the second connecting rod 10 are both integrally formed with a rack, and the first connecting rod 7 is meshed with the top of the gear 13 through the rack, and the second connecting rod 10 is meshed with the bottom of the gear 13 through the rack. The rotation of the gear 13 causes the first connecting rod 7 and the second connecting rod 10 meshed thereon to move relatively synchronously, so that the first connecting rod 7 and the second connecting rod 10 drive the fixing component to extend and retract in the groove of the outer screen 3. When the inner screen 1 is engaged with the outer screen, the fixing component is pulled into the interior of the outer screen 3 by the first connecting rod 7 and the second connecting rod 10, so that the fixing component does not interfere with the engagement of the inner screen 1. When the outer screen 3 wraps around the inner screen 1, the first connecting rod 7 and the second connecting rod 10 push the fixing component to extend and connect with the fixing hole 4 on the side of the inner screen 1 to play a fixing role.

In Figure 3, the end of the first connecting rod 7 is vertically connected to the first sub-rod 8, and the end of the second connecting rod 10 is vertically connected to the second sub-rod 11, and the bottoms of the first sub-rod 8 and the second sub-rod 11 are on the same horizontal line. The first sub-rod 8 and the second sub-rod 11 only play a connecting transition role. The reason is that the gear 13 is arranged at the front and rear ends inside the outer screen 3, and the parts for engaging with the fixing holes 4 are arranged on both sides inside the outer screen 3, with an angle between the two. The first connecting rod 7 and the second connecting rod 10 are installed horizontally, so it is necessary to achieve bending through the longitudinal connection between the first sub-rod 8 and the second sub-rod 11.

In Figure 3, the length of the first sub-rod 8 is the sum of the length of the second sub-rod 11 and the diameter of the gear 13. The first sub-rod 8 and the second sub-rod 11 are connected to the opposite side of the lower end with a mosaic column 5, and the length of the mosaic column 5 is the same as the depth of the fixing hole 4, and the width of the mosaic column 5 is equal to the diameter of the fixing hole 4. The first connecting rod 7 and the second connecting rod 10 can only achieve synchronous relative movement if they are arranged at the upper and lower ends of the gear 13, and the mosaic columns 5 used for fixing need to be on the same straight line. Therefore, there will be a certain length difference between the first sub-rod 8 and the second sub-rod 11, and this difference is the diameter length of the gear 13. When the gear 13 of the fixing mechanism 16 rotates to drive the first connecting rod 7 and the second connecting rod 10 to move relative to each other, the mosaic column 5 is prompted to retract first to make room for the outer screen 3 to wrap the inner screen 1. When the inner screen 1 and the outer screen 3 are fitted together, the gear 13 is rotated counterclockwise to make the first connecting rod 7 and the second connecting rod 10 drive the mosaic column 5 to extend and plug into the fixing hole 4.

In Figures 4 and 5, a short shaft 14 is fixedly connected to the center of the front end of the gear 13, and the short shaft 14 passes through the side wall of the outer screen 3. The end of the short shaft 14 is fixedly connected to a fixing plate 12 at a position deviating from the center of the circle, and a screw hole 15 is opened on the fixing plate 12. A screw groove is opened at the corresponding position of the outer wall of the outer screen 3, and a hole is also opened on the outer screen 3. When the gear 13 of the fixing mechanism 16 rotates, it drives the first connecting rod 7 and the second connecting rod 10 to move relative to each other, so that the mosaic column 5 is first retracted to make room for the outer screen 3 to wrap the inner screen 1. When the inner screen 1 and the outer screen 3 are fitted together, the gear 13 is rotated counterclockwise to make the first connecting rod 7 and the second connecting rod 10 drive the mosaic column 5 to extend and plug into the fixing hole 4. Finally, the screw hole 15 on the fixing plate 12 is aligned with the hole on the outer screen 3, and they are connected with screws to finally realize the constraint of the fixing mechanism.

In Figure 2, a protective pad 2 is attached to the bottom edge of the outer screen 3, and the width of the protective pad 2 is half of the width of the bottom edge of the outer screen 3. The protective pad 2 prevents the outer screen 3 from directly contacting the front frame of the mobile phone, thereby avoiding the glass structure of the outer screen 3 from breaking when squeezed with the metal front frame when under pressure. At the same time, in order to ensure that the user can see the protective pad 2 due to the glass material of the outer screen 3 during use, the width of the protective pad 2 is only set to half of the width of the edge of the outer screen 3, and the edge of the outer screen 3 is covered by the mobile phone frame to eliminate the possibility of the protective pad 2 being seen.

In Figure 3, a slide groove 6 is provided in the middle of the first connecting rod 7 and the second connecting rod 10, and the ends of the first connecting rod 7 and the second connecting rod 10 are pin-connected with a limit rod 9, and the limit rod 9 is slidably connected in the slide groove 6. The purpose of this design is to enable the first connecting rod 7 and the second connecting rod 10 to restrain and control each other during the movement, so that the movement of the first connecting rod 7 and the second connecting rod 10 is smoother and synchronization is ensured.

Working principle: When assembling, first fix the inner screen 1 in the front frame of the mobile phone using the traditional installation method. After the installation is completed, cover the outer screen 3 on the inner screen 1. In this process, the gear 13 inside the outer screen 3 is driven to rotate through the short shaft 14. When the gear 13 of the fixing mechanism 16 rotates, it drives the first connecting rod 7 and the second connecting rod 10 to move relative to each other, causing the embedded column 5 to retract first, making room for the outer screen 3 to wrap the inner screen 1. When the inner screen 1 and the outer screen 3 are fitted together, the gear 13 is rotated counterclockwise, so that the first connecting rod 7 and the second connecting rod 10 drive the embedded column 5 to extend and fit into the fixing hole 4. Plug and finally align the screw holes 15 on the fixing plate 12 with the holes on the outer screen 3, and connect them with screws, finally realizing the constraint of the fixing mechanism. The protective pad 2 prevents the outer screen 3 from directly contacting the front frame of the mobile phone, thereby avoiding the glass structure of the outer screen 3 from breaking when squeezed with the metal front frame when under pressure. At the same time, in order to ensure that the user can see the protective pad 2 due to the glass material of the outer screen 3 during use, the width of the protective pad 2 is only set to half the width of the edge of the outer screen 3, and the edge of the outer screen 3 is covered by the mobile phone frame to eliminate the possibility of the protective pad 2 being seen.

It cannot be determined that the specific implementation of the present invention is limited to these descriptions.
