Description

Technical Field

[0001] The utility model relates to the field of electronic equipment, in particular to a middle frame structure with an externally embedded bent waterproof screen. Background Art

[0002] Smart screen is a large-screen device with mobile phone functions, which brings great convenience to people's lives. Smart screen is assembled with metal middle frame and back cover to meet consumers' demand for metal texture. In the production process of the middle frame, the conventional aluminum frame bending process is greatly limited. Especially when meeting the requirements of external embedded installation and waterproofing, the processing size of the rounded corners and the size of the outer eaves will be limited. It is not only unsightly, but also easy to deform, which has a great impact on the quality and aesthetics of the final product.

[0003] In the technical solution of patent CN 219834654 U, a middle frame prefabricated part, a middle frame structure and an electronic device are provided. The middle frame prefabricated part includes a middle frame structure, a glue injection hole, a slider, a slide groove and a frame. By setting glue injection holes on all four frames, glue is injected with a glue injection needle so that the glue flows into the frame, and the glue is evenly spread in the frame with a slight tilt. The structure designed by the utility model can effectively prevent the glue injection needle from stabbing the screen, so that the frame fits the screen better.

[0004] However, when the middle frame structure and the screen are connected in this solution, it is easy to cause the problem of uneven veneer. At the same time, when installing the middle frame structure and the screen, if the position is offset, it cannot be adjusted, and the fault tolerance rate in the production process is too low. On the other hand, the middle frame structure is still composed of direct bending of alloy. When affected by external force, it is easy to deform, reducing the service life. At the same time, this process has high requirements for the gluing process, and the glue needs to be spread flat in the middle frame. The operation is difficult and takes a long time. In addition, the processing size of the fillet and the size of the outer eaves are highly restricted, and there are few sizes to choose from. Utility Model Content

[0005] The utility model aims to overcome the problems in the prior art that the middle frame itself is easy to deform, has high bending angle requirements and short service life, and provides a middle frame structure with an externally embedded bent waterproof screen.

[0006] A middle frame structure with an externally embedded bent waterproof screen comprises: a middle frame assembly, sheet metal assemblies arranged at both ends of the middle frame assembly, and a touch liquid crystal assembly; the middle frame assembly comprises a vertical frame for connecting and fixing the sheet metal assembly, and a fixed frame for connecting the touch liquid crystal assembly, and the vertical frame and the fixed frame are spliced ​​and connected.

[0007] The middle frame assembly of the present utility model is formed by splicing and connecting a vertical frame and a fixed frame. Before splicing, milling processing is carried out to ensure that the overall thickness of the middle frame assembly remains unchanged. At the same time, the middle frame assembly is formed by splicing, which helps to avoid the problem that the aluminum middle frame is prone to deformation during use. The splicing assembly can increase the mechanical strength of the entire middle frame structure. At the same time, the bending process at the corners of the spliced middle frame structure is better, which can more effectively meet the waterproof screen requirements of the external embedding process, reduce the processing size of the rounded corners and the dimensional limitations of the outer eaves fit, and make the produced products more convenient and beautiful. At the same time, setting two components to be spliced to form the middle frame assembly can reduce the glue injection difficulty. Higher glue injection requirements are adopted for the fixed frame in contact with the screen, and the glue injection requirements for the vertical frame structure connecting the sheet metal assembly are appropriately reduced. While having no actual impact on the quality of the entire structure, it reduces the actual production time and increases the production efficiency.

[0008] The fixed frame includes a first side for connecting the vertical frame and a second side for limiting and connecting the touch liquid crystal component, and the first side and the second side are fixedly connected.

[0009] The fixed frame of the present utility model is used to connect the touch liquid crystal component. The second side can increase the surface area of connection between the middle frame assembly and the touch liquid crystal component, making it better and more stable to connect. At the same time, the second side of the fixed frame can be closely attached to the touch liquid crystal component, which is beneficial to the tight connection between the fixed frame and the touch liquid crystal component after subsequent glue injection, so as to ensure the waterproof effect of the externally embedded and bent screen.

[0010] Preferably, the vertical frame includes a first short side for connecting the fixed frame; a first long side for limiting the displacement of the sheet metal component; and a connecting side for connecting the sheet metal component, connecting the first short side and the first long side.

[0011] The first short side of the present utility model can be tightly connected to the fixed frame, increasing the stability of the middle frame structure; the first long side can be used to limit and connect the sheet metal component inside the middle frame assembly to avoid the displacement of the sheet metal component; the connecting side is used to connect and fix the sheet metal component to avoid the sheet metal component slipping inside the middle frame assembly, increasing the stability of the structure.

[0012] Preferably, the first short side and the fixed frame together form a glue injection groove.

[0013] Glue can be injected into the glue injection groove of the present utility model to connect the touch liquid crystal component, ensuring that the touch liquid crystal component can be firmly fixed on the middle frame assembly. At the same time, injecting glue into the glue injection groove plays a certain waterproof effect, preventing water from entering the sheet metal component through the middle frame assembly and damaging the relevant structures of the mobile phone, affecting the function.

[0014] Preferably, a number of welding points for connecting the fixed frame and the vertical frame are provided in the glue injection groove.

[0015] The utility model avoids the position deviation between the fixed frame and the vertical frame during the glue injection process, and the fixed frame and the vertical frame need to be fixed by welding. Generally, 6-10 welding points can be made to ensure the strength of the structure. Generally, 3 points can be welded on the longer side of the middle frame and 2 points can be welded on the shorter side of the middle frame.

[0016] Preferably, a clamping strip for fixing subsequent devices is provided on one side of the first long side away from the first short side.

[0017] The utility model is provided with the clamping strip, which facilitates the connection of the middle frame assembly to other subsequent structures and ensures the integrity of the whole device.

[0018] Preferably, a connecting plate for connecting the sheet metal assembly is provided on the connecting edge.

[0019] The utility model is provided with a connecting plate to connect the sheet metal assembly, which ensures that the sheet metal assembly can be better fixed, avoids the instability of the sheet metal assembly, and prevents the phenomena that the sheet metal assembly cannot play its role or has a reduced service life.

[0020] Preferably, a plurality of fixing points for connecting the sheet metal assembly are provided on the connecting plate.

[0021] The utility model is provided with a plurality of screws on the connecting plate to be connected and fixed to the sheet metal assembly, which increases the connection stability between the sheet metal assembly and the middle frame assembly and avoids the phenomenon of the sheet metal assembly falling off.

[0022] Preferably, a plurality of wall hanging brackets for fixing the device are provided at one end of the connecting edge away from the sheet metal assembly.

[0023] The wall hanging bracket of the utility model can facilitate the subsequent fixing of the device at other positions, increase the application range of the device, and ensure the stability after fixing.

[0024] Preferably, a connecting hole for connecting the wall hanging bracket is provided on the connecting edge; a connecting strip corresponding to the connecting hole for connecting the wall hanging bracket is provided on the connecting plate.

[0025] The connecting hole and the connecting strip of the utility model can facilitate the fixing of the wall hanging bracket on the middle frame assembly, increase the structural stability, and avoid the phenomenon of loosening and falling off between the wall hanging bracket and the middle frame assembly during the subsequent use process.

[0026] To achieve the above object, the utility model is realized through the following technical solutions:

[0027] Therefore, the utility model has the following beneficial effects:

[0028] (1) The middle frame assembly provided by the present utility model adopts a middle frame splicing process and abandons the traditional direct bending method. It can effectively ensure that the overall thickness of the middle frame assembly is relatively low, while the radius at the corner is relatively small. The overall middle frame assembly is beautiful, not easily deformed, can withstand a large external force, has a long service life, and high mechanical strength. At the same time, the middle frame splicing process can reduce the difficulty of the gluing process. For the side that does not connect to the touch liquid crystal screen, the quality requirements of the gluing process can be appropriately reduced, which can increase the processing efficiency while not affecting the overall quality of the waterproof mobile phone screen product.

[0029] (2) During the gluing process of the present utility model, several welding points are first determined in the gluing groove, and the middle frame assembly is welded. After ensuring that the middle frame assembly is not easily displaced and deformed, the glue filling operation is then carried out, which is beneficial to reducing the disassembly and deformation of the middle frame assembly during the glue filling process and reducing the defective rate of the product.

[0030] (3) The device involved in the present utility model has simple operation and clear structure, which is beneficial to its application and promotion in actual production. Description of the Drawings

Detailed Embodiment

[0038] The present invention will be further described below in conjunction with specific embodiments. Those of ordinary skill in the art will be able to implement the present invention based on these descriptions. In addition, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, rather than all of the embodiments. Therefore, all other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] As Figure 1-4 , this embodiment provides a middle frame structure with an externally embedded bent waterproof screen, which can be divided into a middle frame assembly 10, a sheet metal assembly 20, and a touch liquid crystal assembly 30.

[0041] The middle frame assembly 10 includes a fixed frame 11 for connecting the touch liquid crystal assembly 30 and a vertical frame 12 for connecting and fixing the sheet metal assembly 20. The two are spliced together to form the middle frame assembly 10. While ensuring that the overall thickness of the middle frame assembly remains unchanged, since the middle frame assembly 10 is formed by splicing, it is beneficial to avoid the problem that the aluminum middle frame is prone to deformation during use. The splicing assembly can increase the mechanical strength of the entire middle frame assembly 10. At the same time, the bending process at the corner of the spliced middle frame assembly 10 is better, which can more effectively meet the requirements of the waterproof screen for the externally embedded process, reduce the processing size of the rounded corners and the dimensional limitations of the outer eaves fit, and make the produced products more convenient and beautiful. At the same time, setting two components to be spliced to form the middle frame assembly can reduce the injection molding difficulty, adopt higher injection molding requirements for the fixed frame in contact with the screen, and appropriately reduce the injection molding requirements for the vertical frame structure connecting the sheet metal assembly. While having no actual impact on the quality of the entire structure, it reduces the actual production time and increases the production efficiency.

[0042] In order to better connect the touch liquid crystal assembly 30, the fixed frame 11 is L-shaped, including a first side 111 for connecting the vertical frame 12 and a second side 112 for limiting and connecting the touch liquid crystal assembly 30. The L-shaped structure can increase the surface area of the middle frame assembly connected to the touch liquid crystal assembly, making it better and more stable to connect. At the same time, the second side 112 of the fixed frame can be closely attached to the touch liquid crystal assembly 30, which is beneficial to the tight connection between the fixed frame 12 and the touch liquid crystal assembly 30 after subsequent injection molding to ensure the waterproof effect of the externally embedded bent screen.

[0043] To fix the touch liquid crystal module 30 and the middle frame module 10, glue can be injected into the glue injection groove 14, ensuring that the touch liquid crystal module can be firmly fixed on the middle frame module. Meanwhile, injecting glue into the glue injection groove 14 has a certain waterproof effect, preventing water from entering the sheet metal module 20 through the middle frame module, damaging the relevant structures of the mobile phone and affecting its functions. Meanwhile, to prevent the position between the fixed frame 11 and the vertical frame 12 of the middle frame module 10 from shifting during the glue injection process, the fixed frame 11 and the vertical frame 12 need to be fixed by welding. Generally, 6 - 10 welding points can be made in the glue injection groove 14 to ensure the strength of this structure. Generally, 3 points can be welded on the longer side of the middle frame and 2 points on the shorter side of the middle frame.

[0044] To facilitate the connection of the middle frame module 10 to other subsequent structures, a clamping strip 124 for fixing subsequent devices is provided on one side of the first long side 122 away from the first short side 121, ensuring the integrity of the entire structure. To ensure that the sheet metal module 20 can be better fixed on the middle frame module 10 and avoid the instability of the sheet metal module 20, a connecting plate 15 for connecting the sheet metal module 20 is provided on the connecting edge 123. Meanwhile, to increase the connection stability, a number of fixing points 16 are provided on the connecting plate 15, and a number of screws are connected and fixed to the sheet metal module 20, increasing the connection stability between the sheet metal module 20 and the middle frame module 10 and avoiding the occurrence of the phenomenon that the sheet metal module 20 falls off.

[0045] On the basis of the above - mentioned embodiment, for fixing the device, the middle frame module 10 is further optimized in design.

[0046] As Figure 5-6 , in this embodiment, in order to fix the device on the wall, a number of wall - hanging brackets 17 for fixing the device are provided at one end of the connecting edge 123 away from the sheet metal module 20, increasing the applicable range of the device and ensuring the stability after fixation. To increase the stability of this structure, connection holes 18 for connecting the wall - hanging brackets are provided on the connecting edge 123; connection strips 19 corresponding to connecting the wall - hanging brackets 17 are provided on the connecting plate 15. The connection holes 18 and the connection strips 19 are conducive to fixing the wall - hanging brackets 17 on the middle frame module 10 and avoiding the occurrence of the phenomenon that the wall - hanging brackets 17 and the middle frame module 10 become loose and fall off during subsequent use.

[0047] The specific use process of the embodiment is as follows:

[0048] Connect and fix the fixing frame 11 and the vertical frame 12, connect the first side 111 of the L-shaped fixing frame 11 and the first short side 121 of the Z-shaped vertical frame 12 to form the middle frame assembly 10. A glue injection groove 14 is formed between the fixing frame 11 and the vertical frame 12, and a number of welding points 13 are determined in the glue injection groove 14 for electric welding. Grind the plane of the middle frame assembly 10 in contact with the touch liquid crystal assembly 30 to ensure the flatness of the connection. While injecting glue for fixation in the glue injection groove 14, install the touch liquid crystal assembly 30 above the middle frame assembly 10, and the second side 112 of the fixing frame 11 is connected in a limiting manner to the touch liquid crystal assembly 30. A connecting plate 15 for connecting the sheet metal assembly 20 is provided on the connecting edge 123 of the vertical frame 12, and a number of fixing points 16 for connection are provided on the connecting plate 15. The first long side 122 of the Z-shaped vertical frame 12 is connected to the bottom of the sheet metal assembly 20, which can be used to prevent the sheet metal assembly 20 from falling off. In order to connect subsequent devices, a card strip 124 is provided on the vertical frame. At the same time, during use, the device can be fixed to the target wall surface through the wall hanging bracket 17 provided at one end of the connecting edge 123 away from the sheet metal assembly 20. In order to increase the stability of the connection between the wall hanging brackets 17 and the middle frame assembly 30, connection holes 18 for connecting the wall hanging brackets are provided on the connecting edge 123; connection strips 19 corresponding to the connection holes 18 for connecting the wall hanging brackets 17 are provided on the connecting plate 15, and the wall hanging bracket 17 is connected to the connecting edge 123 and the connecting plate 15 through the connection holes 18 and the connection strips 19 respectively.
