Therefore, during the installation process of the positioning bracket, it is very likely that the screen assembly may be broken due to the impact on the screen assembly, or the screen assembly may be scratched due to the movement relative to the screen assembly during alignment, thereby causing the screen assembly to fail.

3 and 4, an embodiment of the present application provides a camera device, including a screen assembly 10, a fixed housing 20, a positioning bracket 30, and a camera assembly 40 that are connected in sequence. This camera device is used in cameras, mobile phones, tablet computers, personal computers or other terminal equipment.

Wherein, the screen assembly 10 is provided with a light-transmitting structure for the imaging light to be transmitted to the camera assembly 40, and the fixed housing 20 avoids the imaging light. The light-transmitting structure refers to a structure that can transmit light, such as a hole structure, a structure made of a light-transmitting material, or a combination of the two.

It can be understood that, on the basis of ensuring that the TFT array of the TFT glass 131 can perform its display function, the above-mentioned light-transmitting hole 101 may also penetrate the TFT glass 131.

Please refer to FIG. 3 and FIG. 4, the fixed housing 20 avoids imaging light so as to avoid blocking the camera assembly 40. Specifically, the fixed housing 20 is provided with a housing-side avoiding hole 201 for avoiding imaging light, that is, the housing-side avoiding hole 201 avoids the arrangement of the light-transmitting hole 101, so as to avoid the gap between the camera assembly 40 and the light-transmitting hole 101. Imaging light.

3 to 4, the positioning bracket 30 is arranged on the fixed housing 20 and aligned coaxially with the light-transmitting structure, and the camera assembly 40 is arranged on the side of the positioning bracket 30 away from the screen assembly 10, and is the same as the positioning bracket 30 Axis alignment. Wherein, the above-mentioned arrangement and coaxial alignment method is that the positioning bracket 30 is connected to the fixed housing 20 after position alignment with the light-transmitting structure. The positioning bracket 30 is provided with a bracket side avoiding hole 301 to avoid imaging light. The positioning bracket 30 is aligned with the light transmission structure through the bracket side avoiding hole 301, and is connected to the fixed housing 20 after the position calibration. At this time, the bracket side avoids The hole 301 is coaxially aligned with the light transmission hole 101. It should be noted that the above-mentioned coaxial alignment does not limit the stent side avoiding hole 301 and the light-transmitting hole 101 to be circular holes, and may also be hole structures of other shapes. The axis here may be a circular mandrel or other shapes. The central axis of the shape is coaxial, that is, the central axis coincides.

The camera device of the present application is provided with a fixed housing 20 so that the screen assembly 10 and the positioning bracket 30 are connected through the fixed housing 20. The fixed housing 20 has a fixing and strengthening effect on the screen assembly 10, and the positioning bracket 30 is installed to the fixed housing 20. , So that the force-applied object becomes the fixed housing 20, avoiding the positioning bracket 30 being directly connected to the screen assembly 10, thereby preventing the positioning bracket 30 from exerting force on the screen assembly 10, thereby preventing the screen assembly 10 from being scratched or broken, and eliminating The installation of the positioning bracket 30 affects the screen assembly 10.

Please refer to Figures 1 and 2. Existing mobile phones and other terminal devices equipped with a camera assembly 93 are provided on both sides of the fixed housing 92 to make the camera of the camera assembly 93 coaxial with the silk screen hole 911 of the screen assembly 91 The screen end positioning slot 923 and the camera end positioning slot 922 are provided with a through hole 921 at the bottom of the camera end positioning slot 922. When assembling the camera, first install the screen assembly 91 in the screen end positioning slot 923, and then install the camera assembly 93 is installed in the camera-side positioning groove 922. The screen-side positioning groove 923 and the camera-side positioning groove 922 respectively position the screen assembly 91 and the camera assembly 93. However, due to the difference between the screen assembly 91 and the screen-side positioning groove 923 during assembly There may be installation tolerances between the camera assembly 93 and the camera end positioning slot 922. The position of the center of the camera relative to the silk screen hole 911 of the screen assembly 91 includes the accumulation of these two tolerances, which will inevitably lead to the camera and the silk screen hole 911. The inability to maintain the coaxial alignment results in the deterioration of the shooting effect of the camera, which reduces the user experience. In the existing assembly of the screen assembly 91 and the fixed housing 92, although the position of the silk screen hole 911 on the screen assembly 91 is preset to be directly opposite to the through hole 921 of the front shell, due to the existence of tolerances, if the edge of the TP is adjusted Aligning with the edge of the fixed housing 92 cannot take into account the alignment of the silk-screen hole 911 and the through hole 921 of the fixed housing 92. If the alignment accuracy of the silk-screen hole 911 and the through hole 921 of the fixed housing 92 is improved, If the two are calibrated first, it is easy to cause the problem that the TP and the fixed housing 92 cannot be aligned. At the same time, since the side of the camera facing the screen assembly 91 is relatively close to the side of the screen assembly 91 facing the camera, collisions between the camera and the screen assembly 91 are likely to occur when the terminal device falls, causing the screen assembly 91 or the camera assembly 93 to appear. Failure to improve the reliability of the camera device.

In view of the above problems, the camera device has a positioning bracket 30 arranged on the fixed housing 20. By setting the positioning bracket 30 in the camera device, the alignment of the through hole 921 on the fixed housing 92 and the silk screen hole 911 on the screen assembly 91 in the prior art becomes the light transmission of the positioning bracket 30 and the screen assembly 10 in this embodiment. The counterpoint of the structure. Conventionally, adding one more component increases the alignment tolerance of one component at the same time. That is to say, the setting of the positioning bracket 30 should reduce the alignment accuracy of the camera assembly 40 and the light-transmitting structure, and in order to ensure that the fixed housing 20 and the The alignment of the periphery of the screen assembly 10 is accurate, and it is impossible to coaxially align the housing-side avoiding hole 201 of the fixed housing 20 with the light-transmitting hole 101 by means of industrial camera calibration or the like. In this camera device, the position between the positioning bracket 30 and the light-transmitting structure is first calibrated to reduce the tolerance between the positioning bracket 30 and the light-transmitting structure to ensure the coaxiality of the two before installing the positioning bracket 30 to the On the fixed housing 20, it is equivalent to the fixed housing 20 and the positioning bracket 30 forming a new housing structure, which not only ensures the accurate alignment of the fixed housing 20 and the screen assembly 10, but also ensures that the positioning bracket 30 and the transparent The alignment accuracy between the light structures, thus reducing the overall tolerance between the camera assembly 40 and the light-transmitting structure, that is, improving the alignment accuracy between the camera assembly 40 and the light-transmitting structure, thereby improving the camera assembly 40 The shooting effect. Wherein, the shape of the support side avoiding hole 301 and the light-transmitting hole 101 may be regular patterns, such as a circle, a regular polygon, or an irregular pattern, and the shapes of the two may be the same in size. At the same time, due to the setting of the positioning bracket 30, the fixed housing 20 is heightened, and the axial distance between the camera 42 and the screen assembly 10 is increased, so as to prevent the screen assembly from colliding with each other when the distance is too small. 10 or the case where the camera assembly 40 fails.

3 and 5, the positioning bracket 30 and the camera assembly 40 can be installed in snap connection, plug connection, buckle connection, bonding, etc. In this embodiment, the positioning bracket 30 has an insertion slot 302 on the side facing away from the fixed housing 20, and the camera assembly 40 is disposed in the insertion slot 302. As an option, the camera assembly 40 is inserted into the insertion slot 302 and fixedly connected to the positioning bracket 30 through interference fit, so as to realize the rapid alignment and connection of the camera assembly 40 and the positioning bracket 30. Please further refer to FIG. 6, the camera assembly 40 includes a bracket 41 and a camera 42 connected to the bracket 41 and extending toward the light transmission hole 101. When the camera assembly 40 is installed on the positioning bracket 30, the camera 42 and the bracket side avoiding hole 301 are the same Axis alignment settings. 5 again, the bracket side avoiding hole 301 is opened at the bottom of the insertion slot 302 to facilitate the connection of the camera assembly 40 and the positioning bracket 30 and the alignment of the camera 42 with the bracket side avoiding hole 301. In order to prevent the fixed housing 20 and the positioning bracket 30 from blocking the imaging of the camera 42, the camera 42 penetrates through the bracket side escape hole 301 and the housing side escape hole 201 and extends toward the light transmission hole 101. Optionally, the cross section of the insertion groove 302 is non-circular, and the bracket 41 has a shape adapted to the insertion groove 302, so that the camera assembly 40 can be aligned through the insertion groove 302, and the insertion groove 302 faces the camera assembly. 40 plays a limiting role to prevent it from rotating.

5, the fixed housing 20 is provided with a housing side calibration plane 204 on the side facing away from the screen assembly 10. Please further refer to FIG. 7, the positioning bracket 30 is provided with a bracket side calibration plane 304 on the side facing the screen assembly 10. The side calibration plane 304 is attached to the side calibration plane 204 of the housing, and the position between the positioning bracket 30 and the light-transmitting structure is calibrated through relative movement. The housing side calibration plane 204 and the bracket side calibration plane 304 enable the positioning bracket 30 and the fixed housing 20 to be calibrated in the axial direction. The positioning bracket 30 only needs to be attached to the housing side calibration plane 204 on the bracket side calibration plane 304 Performing a translation on the calibration plane 204 on the housing side can perform the calibration in the axial direction, thereby finally completing the calibration of the positioning bracket 30. Among them, the calibration method can be an industrial camera alignment or other alignment equipment assisted alignment.

Please refer to FIG. 5, in this embodiment, the housing side calibration plane 204 and the bracket side calibration plane 304 are joined by glue 50, so as to realize the quick connection between the positioning bracket 30 and the fixed housing 20. The adhesive 50 may be in the form of a fluid or a formed adhesive strip, and can maintain the flatness and adhesion of the housing-side calibration plane 204 and the bracket-side calibration plane 304 in any state.

3 and 5, optionally, a fixing groove 202 is formed on the side of the fixed housing 20 away from the screen assembly 10, and the fixing groove 202 is used to accommodate the positioning bracket 30, and the groove bottom of the fixing groove 202 is for housing side alignment The plane 204, when the positioning bracket 30 is connected to the fixed housing 20, that is, when the bracket side calibration plane 304 is attached to the housing side calibration plane 204, the positioning bracket 30 is left between the positioning bracket 30 and the groove wall of the fixing groove 202. Shift the calibration space 203 for calibration. The calibration space 203 provides a movement space for the translation of the positioning bracket 30 during the calibration process. In addition, because the positioning bracket 30 is pressed toward the bottom of the fixing groove 202, the gap between the housing side calibration plane 204 and the bracket side calibration plane 304 is reduced. When the glue 50 is too much, the glue 50 is squeezed and thinned. It spreads toward the peripheral side and overflows into the calibration space 203 between the positioning bracket 30 and the groove wall of the fixing groove 202. The calibration space 203 is used to prevent the glue 50 from overflowing to other areas of the fixed housing 20, and at the same time prevent the glue 50 from failing. Overflow causes the adhesive layer to be too thick, which affects the adhesion of the housing side calibration plane 204 and the bracket side calibration plane 304 and the alignment of the positioning bracket 30 with the light-transmitting hole 101, and also prevents the adhesive 50 from facing the bracket side avoiding hole 301 or The casing side prevents the hole 201 from overflowing, thereby blocking the imaging light from passing through. That is to say, the fixing groove 202 plays a role in roughly aligning the positioning bracket 30 and restricting the overflow area of the adhesive 50.

5 and 6, specifically, the housing-side avoiding hole 201 is opened at the bottom of the fixing groove 202, and the bracket-side avoiding hole 301 away from the fixed housing 20 is the horn mouth 303, and the outer wall of the camera 42 abuts Connected to the bell mouth 303. The bell mouth 303 has a tapered structure along the installation direction of the camera assembly 40, which plays a role of guiding and positioning. When the camera assembly 40 is inserted into the insertion slot 302, the edge of the camera 42 facing the positioning bracket 30 can abut against the edge of the bell mouth 303. The hole wall, at this time, the bell mouth 303 can guide the camera assembly 40 to move toward the central axis position of the bracket side avoiding hole 301, thus reducing the tolerance between the camera assembly 40 and the bracket side avoiding hole 301, thereby further reducing the camera The tolerance between the component 40 and the light-transmitting hole 101 improves the alignment accuracy or coaxiality of the camera component 40 and the light-transmitting structure, and further improves the photographing effect.

Please further refer to FIG. 8, in one embodiment, the bracket 41 has a plug portion 411 that fits into the plug groove 302, and a truncated cone-shaped guide portion 412 connected to the plug portion 411, and the camera 42 is connected to the guide portion 412. The side wall of the guide portion 412 is adapted to the bell mouth 303 and can be attached to the hole wall of the bell mouth 303, so that the camera assembly 40 can be coaxially aligned along the bell mouth 303, and the guide portion 412 is attached to the camera assembly 40 To the guiding role.

Referring to FIG. 7, in one embodiment, the positioning bracket 30 includes a positioning portion 31 and a limiting portion 32 connected to the peripheral side of the positioning portion 31. The limiting portion 32 is attached to the bottom of the fixing groove 202, and the bracket side calibration plane 304 is provided on the side of the limiting portion 32 facing the fixed casing 20, the positioning portion 31 extends into the avoiding hole 201 on the casing side, and the insertion groove 302 is located at the positioning portion 31, so that the positioning bracket 30 is closer to the screen assembly 10. It is easier to achieve coaxial alignment of the bracket side avoiding hole 301 at a position close to the light-transmitting hole 101. At the same time, the camera assembly 40 inserted in the insertion slot 302 is also closer to the light-transmitting hole 101. Under the premise of ensuring that the camera 42 does not collide with the screen assembly 10 when the camera device is bumped, the pairing of the fixed housing 20 to the camera is reduced. 42 occlusion to ensure good light transmission and imaging effects.

An embodiment of the present application also provides a terminal device, including the camera device provided in the foregoing embodiments.

S2. Align the position between the positioning support 30 and the light-transmitting structure, so that the positioning support 30 and the light-transmitting structure are aligned coaxially. Before this step, glue 50 is applied to the housing side calibration plane 204 or the bracket side calibration plane 304. In this embodiment, the positioning bracket 30 is calibrated with the position of the light-transmitting hole 101 of the light-transmitting structure through an industrial camera. . Specifically, the industrial camera is first arranged on the side of the fixed housing 20 away from the screen assembly 10 and aligned with the light-transmitting hole 101, and then the positioning bracket 30 is moved to the shooting path of the industrial camera, and the bracket side avoiding hole 301 is aligned with the light-transmitting hole 101. The light transmission hole 101 is calibrated until the two are aligned coaxially.
