Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a camera assembly mounting structure and a terminal. Background Art

[0002] The screen-to-body ratio is used to indicate the relative ratio of the screen to the front panel area of ​​a mobile phone. The larger the screen-to-body ratio, the larger the screen is. It is a parameter in the mobile phone's appearance design that is easier to gain visual favor, and mobile phone manufacturers and consumers are paying more attention to it.

[0003] The larger the screen-to-body ratio of a mobile phone, the narrower the frame on the front panel must be. However, the front camera is the device that has the greatest impact on the width of the mobile phone's forehead. That is, if a front camera is set on the front panel of the mobile phone, the corresponding frame must meet certain width requirements. The reason is as follows: the front camera of an existing mobile phone is installed on the middle frame. After the mobile phone falls or bumps, the force and deformation on the middle frame will be directly transmitted to the front camera, causing the front camera to vibrate, and the gap between the front camera and the display screen will fluctuate greatly. To avoid this phenomenon, the existing technology requires that the front camera and the display screen avoid 0.25-0.50mm in the length direction of the mobile phone, thereby preventing the front camera from colliding with the display screen due to vibration, and ensuring the reliability and drop yield of the display screen.

[0004] On the one hand, the installation structure of the front camera requires a large gap between the front camera and the display screen; on the other hand, to increase the screen-to-body ratio, the phone's forehead must be narrower; therefore, structures such as notch screens and retractable front cameras have appeared on the market to deliberately increase the screen-to-body ratio of mobile phones. The notch screen affects the appearance of the product, and inadequate software adaptation will also cause the screen to be blocked, affecting the user experience; the use of a mechanical retractable structure for the front camera will increase product costs and make the phone thicker, which is not conducive to sales.

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0025] The first aspect of the present application provides a camera assembly installation structure, including: a bracket 4, a middle frame 7, and a touch glass 2 installed on the middle frame 7. The bracket 4 is provided with a through hole for the front end of the camera assembly 5 to penetrate, and the end faces of the bracket 4 at both ends of the through hole are respectively connected to the inner side of the touch glass 2 and the camera assembly 5; a gap is left between the middle frame 7 and the camera assembly 5. It can be understood that the present application is a camera assembly installation structure for a terminal, and the terminal can be a mobile terminal such as a mobile phone or a tablet computer, and of course it can also be used in a fixed terminal.

[0026] Specifically, the touch glass 2 is the outermost transparent component. One end of the through hole on the bracket 4 is opposite to the touch glass 2, and the other end is opposite to the camera assembly 5. The front end of the camera assembly 5 is inserted into the through hole of the bracket 4, and the camera assembly 5 is connected to the inner side of the touch glass 2 through the bracket 4. It should be noted that the front end of the camera assembly 5 mentioned here refers to the end where the lens is set, and the other end opposite to it is the rear end of the camera assembly 5, so that the camera assembly 5 can shoot through the touch glass 2. The touch glass 2 is installed on the middle frame 7, and the middle frame 7 includes a frame and a frame for installing other components, and the frame extends in a direction parallel to the touch glass 2; the middle frame 7 does not contact the camera assembly 5. The specific avoidance structure can be to open a hole in the middle frame 7, or the middle frame 7 avoids in the direction away from the camera assembly 5 at the camera assembly 5, etc., as long as it is ensured that the middle frame 7 does not directly contact the camera assembly 5.

[0027] Those skilled in the art should be aware that the display screen 1 is generally installed on the inner side of the touch glass 2. When the camera module is also installed on the touch glass 2, the relative position between the camera assembly 5 and the display screen 1 remains fixed; even if the middle frame 7 is subjected to force, since there is a gap between the camera assembly 5 and the middle frame 7, it will not cause a collision between the camera assembly 5 and the display screen 1; in view of this, after adopting this solution, the distance between the camera assembly 5 and the display screen 1 can be made closer; the thinner the wall thickness between the through hole on the bracket 4 and the display screen 1, the closer the distance between the camera assembly 5 and the display screen 1, and when the wall thickness at this location is 0.15 mm or less, the distance between the camera assembly 5 and the display screen 1 can be less than or equal to 0.15 mm.

[0028] Compared with the prior art, the distance between the camera assembly 5 and the display screen 1 is further reduced, the screen frame at the corresponding position becomes narrower as a whole, and the area of ​​the corresponding screen area is relatively increased; that is, by adopting this solution, the screen-to-body ratio can be further improved, and the screen edge is neat and the appearance effect is good.

[0029] like Figure 1 and Figure 2 As shown, in some embodiments, an opening is provided on one side of the bracket 4 , the opening is connected to the through hole to form a mounting groove, and the opening is opposite to the edge of the display screen 1 mounted on the inner side of the touch glass 2 .

[0030] Specifically, an opening is provided on the side of the bracket 4 opposite to the display screen 1, and the opening is connected to the through hole to form a U-shaped mounting groove to fix the front end of the camera assembly 5; after such a design, the distance between the camera assembly 5 and the end face of the display screen 1 will no longer be limited by the wall thickness of the through hole on the bracket 4, and the edge of the front end of the camera assembly 5 can be completely aligned with the edge of the side of the bracket 4 with the opening or even exceed the edge, so that the distance between the camera assembly 5 and the display screen 1 is closer; according to the distance between the bracket 4 and the edge of the display screen 1, the gap between the camera assembly 5 and the display screen 1 can be completely 0-0.15mm, that is, the two can be close to each other.

[0031] After setting the opening, there is no need to consider the minimum wall thickness of the bracket 4. The bracket 4 can be made of a material with lower strength, such as a material with a little elasticity, to increase the buffer between the touch glass 2 and the camera assembly 5; the distance between the camera assembly 5 and the display screen 1 is smaller, which can be 0-0.15mm. The shape of the opening and the position of the front end of the camera assembly 5 in the opening groove after fixing can be designed according to needs.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments, the width of the mounting slot at the opening is smaller than the maximum width of the mounting slot.

[0033] Specifically, the mounting groove is not only a channel for the camera assembly 5 to frame and shoot, but also an initial positioning piece for the front end of the camera assembly 5, which facilitates the subsequent accurate connection of the camera assembly 5 with the bracket 4; at the same time, in order to avoid the collision of the camera assembly 5 and the display screen 1 during the assembly process, it is necessary to set a limiting element at the opening to avoid the collision of the camera assembly 5 and the display screen 1 during the installation process; for example, a protrusion is set on the inner wall of the mounting groove set on one or both sides of the opening to reduce the width of the opening; or the part of the bracket 4 that cannot be maintained due to the narrow wall thickness is removed, and only a part is retained as a limiting element.

[0034] The smaller width of the opening is beneficial for protecting the camera assembly 5 and the display screen 1 and improving the safety during the assembly process.

[0035] Further, such as Figure 1 As shown, the bracket 4 is attached to the edge of the display screen 1 .

[0036] Specifically, in order to obtain the minimum distance between the camera assembly 5 and the display screen 1, the bracket 4 is directly attached to the edge of the display screen 1, and the installation position of the camera assembly 5 is limited only by the shape of the opening; when the edge of the front end of the camera assembly 5 is aligned with the edge of the bracket 4, the distance from the front end of the camera assembly 5 to the edge of the display screen 1 is 0 mm.

[0037] like Figure 3 and Figure 4 As shown, in some embodiments, the middle frame 7 is provided with a through hole for the camera assembly 5 to partially or completely pass through.

[0038] Specifically, the front end of the camera assembly 5 only has a lens, and the external dimensions of the front end are small, while the rear end of the camera assembly 5 also includes components such as a housing, and the external dimensions gradually increase.

[0039] If the installation space allows, a through hole can be reserved on the middle frame 7 for the entire camera assembly 5 to pass through, so that the camera assembly 5 can be connected to the bracket 4 on the touch glass 2 first, and then the middle frame 7 can be connected to the touch glass 2. When the camera assembly 5 and the touch glass 2 are assembled, there is no influence of the middle frame 7, the operating space is large, and the operation is convenient.

[0040] If the installation space does not allow and there is not enough room to set a larger via hole, then set a smaller via hole that only allows the front half of the camera assembly 5 to pass through. In this way, you can only assemble the middle frame 7 and the touch glass 2 first, and then insert the front half of the camera assembly 5 into the smaller via hole to connect with the bracket 4 on the touch glass 2; the front end of the camera assembly 5 must also be inserted into the through hole or mounting groove on the bracket 4, and coupled with the interference of the middle frame 7, the camera assembly 5 is difficult to install.

[0041] That is, different sizes of vias can be set and assembly procedures of different difficulty can be selected according to the installation space. Of course, if the cost difference between the two assembly procedures is not much, it is natural to choose to set a smaller via to save space.

[0042] like Figure 3 and Figure 4 As shown, in some embodiments, an antenna bracket 9 connected to the middle frame 7 is also included, and the antenna bracket 9 is bonded to the rear end of the camera assembly 5 by foam glue 8.

[0043] Specifically, the antenna bracket 9 is a thin-walled structure extending along the defense line of the touch glass 2. After the antenna bracket 9 is connected to the middle frame 7, the two ends of the camera assembly 5 are opposite to the touch glass 2 and the antenna bracket 9 respectively. In order to further improve the stability of the camera assembly 5, the rear end of the camera assembly 5 is bonded to the antenna bracket 9 using foam glue 8. In this way, the camera assembly 5 is stably installed and fixed, and at the same time, it is not in direct contact with the middle frame 7, and the force deformation of the middle frame 7 cannot be directly transmitted to the camera assembly 5; in addition, the touch glass 2 and the camera assembly 5 are both connected to the touch glass 2, and the relative positions are kept fixed. The force deformation of the middle frame 7 will not cause the camera assembly 5 to collide with the display screen 1; at the same time, the distance between the camera assembly 5 and the display screen 1 can be made closer. From the appearance point of view, the frame of the display screen 1 at the corresponding position is narrower as a whole, and the screen ratio is further increased without affecting the appearance.

[0044] In some embodiments, an antenna bracket 9 connected to the middle frame 7 is also included, and an elastic support pad is provided between the antenna bracket 9 and the rear end of the camera assembly 5, and the elastic support pad is bonded to the antenna bracket 9 and / or the rear end of the camera assembly 5.

[0045] In other words, the camera assembly 5 and the antenna bracket 9 can also be matched in another way: the installation position of the antenna bracket 9 remains unchanged, still connected to the middle frame 7 and opposite to the rear end of the camera assembly 5; the elastic support pad is supported between the rear end of the camera assembly 5 and the antenna bracket 9, and the elastic support pad is bonded to the camera assembly 5 or the antenna bracket 9, which is convenient for installation and disassembly; of course, in order to ensure the stability of the camera assembly 5, the two sides of the elastic support can also be bonded to the camera assembly 5 and the antenna bracket 9 respectively. The elastic support can play a certain buffering role after the antenna bracket 9 is deformed by force, preventing the camera assembly 5 from being transferred to the touch glass 2 after being subjected to force, and protecting the camera assembly 5 and the touch glass 2. The elastic support can be set into a ring structure to reduce the adhesive area and the weight of the elastic support.

[0046] like Figure 2As shown, in some embodiments, the bracket 4 is bonded to the inner side of the touch glass 2 through the adhesive layer 3. The bracket 4 and the touch glass 2 need to be stably connected without relative displacement, and the operating space is very small, so the dispensing or back glue process is selected for bonding, which is convenient for operation.

[0047] Of course, other combinations can also be used to achieve the connection between the bracket 4 and the touch glass 22. For example, a clamping element matching the bracket 4 is provided on the inner side of the touch glass 2 to Figure 1 Taking the position shown as an example, the clamping element can be set on the protective glass on the left and right sides of the bracket. The clamping element can be: a hard component bonded to the touch glass 2, formed by solidifying the colloid bonded to the inner side of the touch glass 2, or made of glass. The clamping element is made of glass, which means that the clamping element and the touch glass 2 are made into an integrated structure when processing the touch glass 2. The inner wall of the clamping element is connected with the outer edge of the bracket 4, and the connecting surfaces of the two can be provided with grooves for clamping, elastic protrusions, etc. to achieve cooperation, facilitate assembly, and prevent the bracket 4 from moving away from the touch glass 2.

[0048] As for the connection between the bracket 4 and the camera assembly 5, they can be connected by gluing, snapping, etc., but generally gluing, which is more convenient to operate, is selected, such as using foam glue 8 to form an adhesive layer 6; snapping can be understood as setting a buckle, elastic protrusion, etc. between the bracket 4 and the camera assembly 5 to prevent the two from moving away from each other, thereby achieving connection. Regardless of the connection method used, it is necessary to ensure that there is no relative displacement between the bracket 4 and the camera assembly 5.

[0049] In some embodiments, the camera assembly 5 is a front camera assembly. The screen-to-body ratio generally refers to the proportion of the display screen 1 on the front panel appearance, so this application is preferably applied to the installation of the front camera assembly. Of course, it is not excluded that it can be applied to the installation and fixation of the secondary screen camera, so as to further increase the area of ​​the secondary screen within the limited installation space.

[0050] like Figure 4 As shown, the second aspect of the present application also provides a terminal, including: a camera assembly 5, a display screen 1, and the camera assembly installation structure of the first aspect. The connection relationship and position relationship between some components of the terminal have been described in the camera assembly installation structure part. As for the back cover 10, it is installed on the middle frame 7 to protect the components inside the terminal, shield the internal components, and enhance the aesthetics of the entire terminal. It can be immediately noted that the terminal mentioned here can be a mobile terminal such as a mobile phone or a tablet computer, and of course it can also be used on a fixed terminal.

[0051] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0052] The above is only a specific implementation of the present application, so that those skilled in the art can understand or implement the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments described herein, but will conform to the widest scope consistent with the principles and novel features applied for herein.
