The existing mobile phone and other terminal equipment with cameras are generally provided with a screen assembly and a camera, the screen assembly at least comprises a TP (Touch Panel), a screen printing hole is formed in the TP, the existing camera device is provided with a positioning support with a positioning hole for aligning the camera with the screen printing hole, the positioning support is directly connected to the screen assembly, the positioning hole and the screen printing hole of the screen assembly are coaxially arranged, and the camera is installed on the positioning support to improve the alignment precision of the camera and the screen printing hole, but the screen assembly is made of brittle materials and is easy to crack when being pressed or impacted by external force locally. Therefore, the positioning bracket is highly likely to crush the screen assembly due to impact against the screen assembly or scratch the screen assembly due to movement relative to the screen assembly at the time of alignment during installation, thereby causing failure of the screen assembly.
Referring to fig. 3 and 4, an image capturing apparatus according to an embodiment of the present application includes a screen assembly 10, a fixed housing 20, a positioning bracket 30, and an image capturing assembly 40 connected in sequence. The camera device is applied to cameras, mobile phones, tablet computers, personal computers or other terminal equipment.
The screen assembly 10 is provided with a light-transmitting structure for transmitting imaging light to the camera assembly 40, and the fixed housing 20 avoids the imaging light. The light-transmitting structure refers to a structure capable of transmitting light, such as a hole structure, a structure made of a light-transmitting material, or a combination of the two. In this embodiment, referring to fig. 5, taking a mobile phone as an example, the screen assembly 10 includes a TP11, an optically transparent adhesive 12, and a display screen 13, which are sequentially connected, wherein the screen assembly 10 may be a Liu Haibing, a water drop screen, a hole digging screen, etc., and the light-transmitting structure may be a silk-screen hole formed on the display screen 13.
In one embodiment, the display 13 includes TFT (Thin Film Transistor ) glass 131 and a backlight module 132, and the light-transmitting structure is at least penetrating through the light-transmitting hole 101 of the backlight module 132. Referring to fig. 5, the light-transmitting structure includes a light-transmitting hole 101 penetrating through the optically transparent adhesive 12 and the backlight module 132, and a TFT glass 131 corresponding to the light-transmitting hole 101, i.e. a blind hole structure. It is understood that the light-transmitting hole 101 may penetrate the TFT glass 131, while ensuring that the TFT array of the TFT glass 131 can perform its display function.
Referring to fig. 3 and 4, the fixed housing 20 avoids the imaging light to avoid obscuring the camera assembly 40. Specifically, the fixed housing 20 is provided with a housing-side avoidance hole 201 for avoiding imaging light, that is, the housing-side avoidance hole 201 is provided for avoiding the light hole 101 so as to avoid imaging light between the imaging assembly 40 and the light hole 101.
Referring to fig. 3 to 4, the positioning bracket 30 is disposed on the fixed housing 20 and aligned coaxially with the light-transmitting structure, and the camera assembly 40 is disposed on a side of the positioning bracket 30 facing away from the screen assembly 10 and aligned coaxially with the positioning bracket 30. Wherein, the positioning bracket 30 is connected to the fixed housing 20 after being aligned with the light-transmitting structure. The positioning bracket 30 is provided with a bracket side avoiding hole 301 so as to avoid imaging light, and the positioning bracket 30 performs position calibration through the bracket side avoiding hole 301 and the light transmission structure and is connected to the fixed housing 20 after the position calibration, and at this time, the bracket side avoiding hole 301 and the light transmission hole 101 are coaxially aligned. The coaxial alignment is not limited to the circular shape of the bracket side escape hole 301 and the light transmission hole 101, and may have other hole structures, and the axis may be the center axis or the center axis of other shapes, that is, the center axis may be coaxial.
According to the image pickup device, the screen assembly 10 and the positioning bracket 30 are connected through the fixed shell 20 by arranging the fixed shell 20, the fixed shell 20 has fixing and reinforcing effects on the screen assembly 10, the positioning bracket 30 is arranged on the fixed shell 20, so that a forced object becomes the fixed shell 20, the positioning bracket 30 is prevented from being directly connected with the screen assembly 10, the positioning bracket 30 is prevented from forcing the screen assembly 10, the screen assembly 10 is prevented from being scratched or crashed, and the influence of the installation of the positioning bracket 30 on the screen assembly 10 is eliminated.
Referring to fig. 1 and 2, in order to make the camera of the camera assembly 93 coaxial with the screen hole 911 of the screen assembly 91, two sides of the fixed housing 92 are respectively provided with a screen end positioning groove 923 and a camera end positioning groove 922, the camera end positioning groove 922 is provided with a through hole 921 at the bottom, when the camera is assembled, the screen assembly 91 is firstly installed in the screen end positioning groove 923, then the camera assembly 93 is installed in the camera end positioning groove 922, the screen end positioning groove 923 and the camera end positioning groove 922 respectively perform positioning functions on the screen assembly 91 and the camera assembly 93, but due to possible installation tolerances between the screen assembly 91 and the screen end positioning groove 923 and between the camera assembly 93 and the camera end positioning groove 922, the position of the camera center relative to the screen hole 911 of the screen assembly 91 contains the accumulation of the two tolerances, which inevitably results in that the camera cannot be coaxially aligned with the screen hole, so that the shooting effect of the camera is poor, and the user experience 911 is reduced. In the conventional assembly of the screen assembly 91 and the fixed housing 92, although the position of the screen hole 911 on the screen assembly 91 is preset to be opposite to the front case through hole 921, if the edge of TP is aligned with the edge of the fixed housing 92 due to the existence of the tolerance, the alignment of the screen hole 911 and the through hole 921 on the fixed housing 92 cannot be considered, and if the alignment of the screen hole 911 and the through hole 921 of the fixed housing 92 is first performed to improve the alignment accuracy of the screen hole 911 and the through hole 921 of the fixed housing 92, the problem that the TP and the fixed housing 92 cannot be aligned is easily caused. Meanwhile, as the distance from the camera towards the side of the screen assembly 91 to the side of the screen assembly 91 towards the camera is relatively short, the collision between the camera and the screen assembly 91 is easy to occur when the terminal equipment falls, so that the screen assembly 91 or the camera assembly 93 is invalid, and the reliability of the camera device is improved.
In view of the above, the present imaging apparatus is provided with the positioning bracket 30 on the fixed housing 20. The image capturing device is provided with the positioning bracket 30, so that the alignment between the through hole 921 on the fixing housing 92 and the screen hole 911 on the screen assembly 91 in the prior art is changed into the alignment between the positioning bracket 30 and the light-transmitting structure of the screen assembly 10 in the present embodiment. Conventionally, the addition of one more component increases the alignment tolerance of one component at the same time, that is, the positioning bracket 30 is set to reduce the alignment accuracy of the image capturing device 40 and the light transmitting structure, and in order to ensure the alignment accuracy of the periphery of the fixed housing 20 and the screen device 10, the housing side avoiding hole 201 of the fixed housing 20 and the light transmitting hole 101 cannot be coaxially aligned in the manners of industrial camera calibration and the like. In this camera device, the position between the positioning bracket 30 and the light-transmitting structure is calibrated, the tolerance between the positioning bracket 30 and the light-transmitting structure is reduced, the coaxiality of the positioning bracket and the light-transmitting structure is ensured, and then the positioning bracket 30 is mounted on the fixed housing 20, which is equivalent to the structure that the fixed housing 20 and the positioning bracket 30 form a new housing structure, which not only ensures the peripheral alignment accuracy of the fixed housing 20 and the screen assembly 10, but also ensures the alignment accuracy between the positioning bracket 30 and the light-transmitting structure, so that the tolerance between the camera assembly 40 and the light-transmitting structure is reduced as a whole, namely, the alignment accuracy between the camera assembly 40 and the light-transmitting structure is improved, and further the shooting effect of the camera assembly 40 is improved. The shapes of the bracket side avoiding holes 301 and the light transmitting holes 101 may be regular patterns, such as circles, regular polygons, or irregular patterns, and the shapes of the two may be the same. Meanwhile, due to the arrangement of the positioning support 30, the fixed shell 20 is raised, the axial distance between the camera 42 and the screen assembly 10 is increased, and the situation that the screen assembly 10 or the camera assembly 40 fails due to mutual collision when falling due to too small distance between the camera 42 and the screen assembly 10 is avoided.
Referring to fig. 3 and 5, the positioning bracket 30 and the camera module 40 may be mounted by clamping, plugging, fastening, bonding, etc. In this embodiment, the positioning bracket 30 has a socket 302 on a side facing away from the fixed housing 20, and the camera module 40 is disposed in the socket 302. Alternatively, the camera module 40 is inserted into the insertion slot 302 and fixedly connected with the positioning bracket 30 through an interference fit, so as to achieve rapid alignment and connection between the camera module 40 and the positioning bracket 30. Referring to fig. 8, the camera assembly 40 includes a bracket 41 and a camera 42 connected to the bracket 41 and extending toward the light hole 101, and when the camera assembly 40 is mounted on the positioning bracket 30, the camera 42 and the bracket side avoiding hole 301 are coaxially aligned. Referring to fig. 5 again, the bracket-side avoiding hole 301 is formed at the bottom of the plugging slot 302, so as to facilitate the connection between the camera assembly 40 and the positioning bracket 30 and the alignment between the camera 42 and 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 is inserted into the bracket side avoiding hole 301 and the housing side avoiding hole 201 and extends toward the light hole 101. Optionally, the cross section of the plugging slot 302 is non-circular, and the bracket 41 is in a shape matching with the plugging slot 302, so that the camera module 40 can be aligned through the plugging slot 302, and the plugging slot 302 plays a limiting role on the camera module 40 to prevent the camera module from rotating.
Referring to fig. 5, the side of the fixed housing 20 facing away from the screen assembly 10 is provided with a housing-side calibration plane 204, and referring to fig. 7, the side of the positioning bracket 30 facing towards the screen assembly 10 is provided with a bracket-side calibration plane 304, and the bracket-side calibration plane 304 is attached to the housing-side calibration plane 204 and calibrates the position between the positioning bracket 30 and the light-transmitting structure by relative movement. The shell side calibration plane 204 and the bracket side calibration plane 304 enable the positioning bracket 30 and the fixed shell 20 to be calibrated in the axial direction, and the positioning bracket 30 can be calibrated in the axial direction only by translating on the shell side calibration plane 204 after the bracket side calibration plane 304 is attached to the shell side calibration plane 204, thereby finally completing the calibration of the positioning bracket 30. The calibration mode may be alignment by an industrial camera or other calibration devices.
Referring to fig. 5, in the present embodiment, the housing-side alignment plane 204 and the bracket-side alignment plane 304 are joined by the adhesive 50 so as to achieve the quick connection of the positioning bracket 30 and the fixed housing 20. The adhesive 50 may be fluid or shaped as a strip of glue, and in any state, the flatness and fit between the housing-side calibration plane 204 and the bracket-side calibration plane 304 can be maintained.
Referring to fig. 3 and 5, alternatively, a fixing groove 202 is formed on a side of the fixing housing 20 facing away from the screen assembly 10, the fixing groove 202 is used for accommodating the positioning bracket 30, the bottom of the fixing groove 202 is a housing side calibration plane 204, and when the positioning bracket 30 is connected to the fixing housing 20, i.e. the bracket side calibration plane 304 is attached to the housing side calibration plane 204, a calibration space 203 for performing translational calibration on the positioning bracket 30 is reserved between the positioning bracket 30 and the wall of the fixing groove 202. The calibration space 203 provides a movement space for translation of the positioning bracket 30 during calibration. In addition, since 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 adhesive 50 is too much, the adhesive 50 is pressed and thinned and spread 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 for preventing the adhesive 50 from overflowing into other areas of the fixing housing 20, and simultaneously preventing the adhesive layer from being too thick due to the failure of the adhesive 50, which affects the adhesion between the housing-side calibration plane 204 and the bracket-side calibration plane 304 and the alignment between the positioning bracket 30 and the light-transmitting hole 101, and also prevents the adhesive 50 from overflowing toward the bracket-side avoidance hole 301 or the housing-side avoidance hole 201, thereby causing the shielding of imaging light. That is, the fixing groove 202 plays a role of roughly aligning the positioning bracket 30 and limiting the overflow area of the adhesive 50.
Referring to fig. 5 and 6, specifically, the housing side avoidance hole 201 is formed at the bottom of the fixed slot 202, the opening of the bracket side avoidance hole 301 facing away from the fixed housing 20 is a flare 303, and the outer sidewall of the camera 42 abuts against the flare 303. The horn mouth 303 is the convergent structure along the installation direction of the subassembly 40 of making a video recording, has played direction and counterpoint effect, and the border of camera 42 towards locating support 30 when the subassembly 40 of making a video recording is pegged graft in spliced groove 302 can support in the pore wall of horn mouth 303, and the center pin position that the subassembly 40 of making a video recording dodges hole 301 towards the support side can be guided to the horn mouth 303 this moment removes, just so reduced the tolerance between subassembly 40 of making a video recording and the support side dodges hole 301, thereby further reduced the tolerance between subassembly 40 of making a video recording and the light trap 101, improved the counterpoint precision or the axiality of subassembly 40 of making a video recording and light-transmitting structure, further improved the shooting effect.
Referring to fig. 8, in one embodiment, the bracket 41 has a plugging portion 411 adapted to the plugging slot 302 and a guiding portion 412 connected to the plugging portion 411 and having a truncated cone shape, the camera 42 is connected to the guiding portion 412, and a side wall of the guiding portion 412 is adapted to the flare 303 and can be attached to a wall of the flare 303, so that the camera assembly 40 can be coaxially aligned along the flare 303, and the guiding portion 412 plays a guiding role on the camera assembly 40.
Referring to fig. 7, in one embodiment, the positioning bracket 30 includes a positioning portion 31 and a limiting portion 32 connected to a peripheral side of the positioning portion 31, the limiting portion 32 is attached to a bottom of the fixing groove 202, the bracket-side calibration plane 304 is disposed on a side of the limiting portion 32 facing the fixing housing 20, the positioning portion 31 extends into the housing-side avoidance hole 201, the plugging slot 302 is disposed on the positioning portion 31, so that the positioning bracket 30 is closer to the screen assembly 10, and the bracket-side avoidance hole 301 is easier to coaxially align at a position close to the light hole 101. Meanwhile, the camera assembly 40 inserted in the inserting groove 302 is closer to the light hole 101, and shielding of the fixed shell 20 to the camera 42 is reduced on the premise that the camera 42 does not collide with the screen assembly 10 when the camera device is bumped, so that good light transmission and imaging effects are guaranteed.
The embodiment of the application also provides a terminal device comprising the image pickup device provided by the above embodiments. The image capturing device has the same structural features as those of the image capturing device in the above embodiments, and functions the same, and will not be described here. The terminal equipment comprises, but is not limited to, a camera, a mobile phone, a tablet computer and a personal computer, and can also be other equipment with a camera device.
The embodiment of the application further provides an assembly method of the image pickup device, which comprises the following steps:
s1, assembling the screen assembly 10 to the fixed housing 20, wherein the fixed housing 20 is made to avoid the imaging light passing through the light-transmitting structure, that is, the housing-side avoiding hole 201 is made to avoid the light-transmitting structure of the screen assembly 10.
S2, calibrating the position between the positioning support 30 and the light-transmitting structure, so that the positioning support 30 and the light-transmitting structure are coaxially aligned. Before this step is performed, the adhesive 50 is dispensed prior to the case-side calibration plane 204 or the bracket-side calibration plane 304, and in this embodiment, the positioning bracket 30 calibrates the position of the light-transmitting hole 101 of the light-transmitting structure by an industrial camera. Specifically, the industrial camera is first disposed on the side of the fixed housing 20 facing away from the screen assembly 10 and aligned with the light hole 101, and then the positioning bracket 30 is moved onto the photographing path of the industrial camera, so that the bracket side avoiding hole 301 and the light hole 101 are aligned until the two are coaxially aligned.
And S3, connecting the positioning bracket 30 to the fixed shell 20. Specifically, the positioning bracket 30 is placed in the fixing groove 202 such that the bracket side alignment plane 304 of the positioning bracket 30 is attached to the housing side alignment plane 204 of the fixing housing 20, and the positioning bracket 20 is aligned with the light-transmitting structure by translating in the fixing groove 202, that is, the bracket side alignment plane 304 is moved radially relative to the housing side alignment plane 204 until the positioning bracket 30 is aligned with the central axis of the light-transmitting structure. This calibration may be the first calibration performed by the calibration method of the industrial camera alignment in step S2, or the recalibration performed by repeating the calibration method of the industrial camera alignment in step S2, wherein the amount of the adhesive 50 is set to fill the calibration space 203 as an upper limit.
S4, assembling the camera module 40 to the positioning bracket 30, and coaxially aligning the camera module 40 with the positioning bracket 30. That is, the camera module 40 is inserted into the insertion groove 302 and the camera 42 of the camera module 40 is inserted into the bracket-side avoiding hole 301, wherein the camera module 40 can move along the flare 303 toward the central axis of the bracket-side avoiding hole 301 by moving toward the flare 303 until being coaxially aligned with the bracket-side avoiding hole 301.
In the above method, after the positioning bracket 30 is attached to the housing side calibration plane 204 of the fixed housing 20 at the bracket side calibration plane 304, the alignment with the central axis of the light-transmitting structure is performed by radially moving the bracket side calibration plane 304 relative to the housing side calibration plane 204, so that the positioning bracket 30 can perform axial alignment while maintaining the radial direction unchanged, thereby realizing rapid alignment of the positioning bracket 30 and the light-transmitting structure and improving the alignment reliability of the positioning bracket 30. The industrial camera adopts a visual alignment mode to calibrate the position of the positioning bracket 30, has high alignment precision and sensitivity and strong reliability, and greatly improves the alignment precision between the positioning bracket 30 and the light-transmitting structure. The camera assembly 40 is coaxially aligned with the bracket side avoiding hole 301 through the horn mouth 303, so that the alignment precision between the camera assembly 40 and the positioning bracket 30 is improved. Therefore, the assembly method reduces the tolerance between the positioning bracket 30 and the light-transmitting structure and the tolerance between the camera shooting assembly 40 and the positioning bracket 30, thereby greatly improving the alignment precision between the camera shooting assembly 40 and the light-transmitting structure and further improving the shooting effect of the camera shooting assembly 40.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the application.
