[0002] In the field of camera inspection technology, to test the imaging function of a camera module in bright or dark environments, a light shield is typically placed between the camera module and the lamp body. The light shield is connected to a driving component, which drives the light shield to reciprocate between the camera module and the lamp body. When the light shield is close to the camera module, it covers the camera module, preventing light from the lamp body from reaching it, thus creating a dark environment. When the light shield is away from the camera module, the camera module is unobstructed, allowing light from the lamp body to reach it, creating a bright environment. However, the driving component is usually installed in the middle area of ​​the light shield. During movement, the two ends of the light shield are prone to tilting, causing the light shield to wobble and affecting the accuracy of the test results. Utility Model Content

[0039] In the field of camera inspection technology, to test the imaging function of a camera module in bright or dark environments, a light shield is typically placed between the camera module and the lamp body. The light shield is connected to a driving component, which drives the light shield to reciprocate between the camera module and the lamp body. When the light shield is close to the camera module, it covers the camera module, preventing light from the lamp body from reaching it, thus creating a dark environment. When the light shield is away from the camera module, the camera module is unobstructed, allowing light from the lamp body to reach it, creating a bright environment. However, the driving component is usually installed in the middle area of ​​the light shield. During movement, the two ends of the light shield are prone to tilting, causing the light shield to wobble and affecting the accuracy of the test results.

[0040] Therefore, some embodiments of this utility model propose a light-shielding device 1000, applied to a camera testing device 2000. The camera testing device 2000 includes camera modules 2100 and lamp bodies 2200 arranged at intervals, as detailed below. Figures 1 to 7 The light-shielding device 1000 is described below.

[0041] Reference Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment of the present invention, the light-shielding device 1000 includes a bracket 100, two slide rails 410, two sliders 420, a light-shielding plate 200, and a driving assembly 300. The bracket 100 is disposed on one side of the camera module 2100. The bracket 100 is provided with two slide rails 410, which are spaced apart. The slide rails 410 extend along the arrangement direction of the camera module 2100 and the bracket 100. Specifically, the bracket 100 and the camera module 2100 are arranged along the width direction of the light-shielding device 1000. The bracket 100 is disposed on the front side of the camera module 2100, and the slide rails 410 are disposed on the upper side of the bracket 100 and fixedly connected to the bracket 100. The two slide rails 410 are spaced apart along the length direction of the light-shielding device 1000, and the slide rails 410 extend along the width direction of the light-shielding device 1000.

[0042] Reference Figure 2 , Figure 3 and Figure 5As shown, in this embodiment, two sliders 420 are slidably connected to two slide rails 410 in a one-to-one correspondence. Specifically, the slider 420 is provided with a groove 421, which passes through the slider 420 along the width direction of the light-shielding device 1000. The slide rail 410 passes through the groove 421, thereby realizing the sliding connection between the slide rail 410 and the slider 420. In this embodiment, the light-shielding plate 200 is disposed on one side of the camera module 2100 and located between the two sliders 420. The two ends of the light-shielding plate 200 are connected to the two sliders 420 in a one-to-one correspondence. Specifically, the light-shielding plate 200 is located on the front side of the camera module 2100 and on the upper side of the bracket 100. Slider 420s are respectively installed on the two ends of the light-shielding plate 200. In this embodiment, the driving component 300 is mounted on the bracket 100 and connected to the light-shielding plate 200. The driving component 300 is configured to drive the light-shielding plate 200 to move along the line connecting the camera module 2100 and the bracket 100 between the spaced-apart camera module 2100 and lamp body 2200. It can be understood that the driving component 300 drives the light-shielding plate 200 to move along the width direction of the light-shielding device 1000, and the light-shielding plate 200 drives the slider 420 to move along the extension direction of the slide rail 410.

[0043] Based on this, refer to Figure 1 and Figure 7 As shown, when the driving component 300 drives the light shield 200 to move along the arrangement direction of the camera module 2100 and the bracket 100, the sliders 420 at both ends of the light shield 200 move along the slide rail 410, so that the two ends of the light shield 200 move synchronously, reducing the risk of the light shield 200 tilting, thereby improving the movement stability of the light shield 200, and further improving the stability and reliability of the light shielding device 1000, and further improving the accuracy of the test results.

[0044] Reference Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment of the present invention, the driving assembly 300 includes a driving device 310, a first connecting member 320, and two second connecting members 330. Both ends of the first connecting member 320 are rotatably connected to the two second connecting members 330. Specifically, along the length of the light-shielding device 1000, both ends of the first connecting member 320 are connected to the second connecting members 330. One end of the second connecting member 330 is rotatably connected to the first connecting member 320, and the end of the second connecting member 330 facing away from the first connecting member 320 is rotatably connected to the light-shielding plate 200. In this embodiment, the driving device 310 is located below the first connecting member 320 and connected to it. It can be understood that the driving device 310 is used to drive the first connecting member 320 to move along the height direction of the bracket 100, thereby causing the first connecting member 320 to move the light-shielding plate 200 through the second connecting members 330.

[0045] Understandably, when the driving device 310 drives the first connecting member 320 to move up and down, the first connecting member 320 will drive the second connecting member 330 to rotate around the first connecting member 320 as a pivot. When the second connecting member 330 rotates around the first connecting member 320, the end of the second connecting member 330 facing away from the first connecting member 320 will move towards or away from the first connecting member 320, thereby driving the light-shielding plate 200 to move along the width direction of the light-shielding device 1000. Based on this, the driving assembly 300 can drive both ends of the light-shielding plate 200 simultaneously, thereby improving the stability of the movement of the light-shielding plate 200 driven by the driving assembly 300.

[0046] Reference Figure 3 , Figure 4 and Figure 6 As shown in the embodiment of this utility model, the drive assembly 300 further includes a first rotating member 331, a second rotating member 332, and a first fastener (not shown in the figure). The first rotating member 331 is mounted on the end of the second connecting member 330 facing the first connecting member 320. Specifically, the end of the second connecting member 330 facing the first connecting member 320 is provided with a first mounting groove 335. The first mounting groove 335 passes through the second connecting member 330 along the length direction of the light-shielding device 1000. The first rotating member 331 passes through the mounting groove and is fixedly connected to the second connecting member 330. In this embodiment, one end of the second rotating member 332 passes through the first rotating member 331, and the other end passes through the first connecting member 320. Specifically, the left end of the second rotating member 332 passes through the first rotating member 331, and the right end of the second rotating member 332 passes through the first connecting member 320.

[0047] Reference Figure 6 As shown, in this embodiment, the second rotating member 332 is provided with a first through hole 3321. The first through hole 3321 extends through the second rotating member 332 along the length direction of the light-shielding device 1000. The first fastener passes through the first through hole 3321 and is connected to the first connecting member 320. It can be understood that the first rotating member 331 and the second rotating member 332 can rotate relative to each other around the length direction of the light-shielding device 1000. Based on this, the rotational connection between the second connecting member 330 and the first connecting member 320 is realized, and the rotational stability of the second connecting member 330 and the first connecting member 320 is improved, thereby increasing the reliability and stability of the light-shielding device 1000.

[0048] Reference Figure 3 , Figure 4 and Figure 6As shown in this embodiment of the invention, the drive assembly 300 further includes a third rotating member 333, a fourth rotating member 334, and a second fastener (not shown in the figure). The second rotating member 332 is mounted on the end of the second connecting member 330 facing away from the first connecting member 320. Specifically, the end of the second connecting member 330 facing away from the first connecting member 320 is provided with a second mounting groove 336. The second mounting groove 336 passes through the second connecting member 330 along the length direction of the light-shielding device 1000. The third rotating member 333 passes through the second mounting groove 336 and is fixedly connected to the second connecting member 330. In this embodiment, one end of the fourth rotating member 334 passes through the third rotating member 333, and the other end passes through the light-shielding plate 200. Specifically, the right end of the fourth rotating member 334 passes through the third rotating member 333, and the left end of the second rotating member 332 passes through the light-shielding plate 200.

[0049] Reference Figure 6 As shown, in this embodiment, the fourth rotating member 334 is provided with a second through hole 3341, which extends through the fourth rotating member 334 along the length direction of the light-shielding device 1000. A second fastener passes through the second through hole 3341 and is connected to the light-shielding plate 200. It is understood that the third rotating member 333 and the fourth rotating member 334 can rotate relative to each other around the length direction of the light-shielding device 1000. Based on this, a rotational connection between the second connecting member 330 and the light-shielding plate 200 is achieved, and the rotational stability of the second connecting member 330 and the light-shielding plate 200 is improved, thereby enhancing the reliability and stability of the drive assembly 300.

[0050] Reference Figure 2 , Figure 3 and Figure 4As shown, in this embodiment of the present invention, the light-shielding device 1000 further includes two guide components 500. Along the length of the light-shielding device 1000, the two guide components 500 are spaced apart and respectively connected to the opposite ends of the first connecting member 320. In this embodiment, the guide component 500 includes a guide shaft 510 and a guide member 520. The guide member 520 is mounted on the bracket 100 and has a guide hole 521. The guide hole 521 extends through the guide member 520 along the height direction of the bracket 100. One end of the guide shaft 510 is connected to the first connecting member 320, and the other end passes through the guide hole 521. Specifically, the guide member 520 is located below the first connecting member 320 and is fixedly connected to the bracket 100. The guide shaft 510 extends along the height direction of the bracket 100, with its upper end fixedly connected to the first connecting member 320 and its lower end passing through the guide hole 521. Based on this, when the drive assembly 300 drives the first connector 320 to move along the height direction of the light-shielding device 1000, the guide shaft 510 moves along the guide hole 521, thereby improving the movement stability of the first connector 320, thereby improving the stability and reliability of the drive assembly 300, and further improving the movement stability of the light-shielding plate 200.

[0051] Reference Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment of the present invention, the bracket 100 is provided with a first mounting plate 110, which is spaced apart from the first connecting member 320. Specifically, the first mounting plate 110 is located on the lower side of the first connecting member 320. In this embodiment, the first mounting plate 110 extends along the length direction of the light-shielding device 1000. The two opposite ends of the first mounting plate 110 are fixedly connected to the bracket 100. The two opposite ends of the first mounting plate 110 are provided with mounting holes 111. The two mounting holes 111 and the two guide members 520 correspond one-to-one. The mounting holes 111 penetrate the first mounting plate 110 along the height direction of the bracket 100, and the guide members 520 pass through the mounting holes 111 and are fixedly connected to the first mounting plate 110. In this embodiment, the guide members 520 and the first mounting plate 110 can be connected by fasteners or by other connection methods such as snap-fit ​​connections. This embodiment does not limit this connection. In this embodiment, the drive device 310 is mounted on the first mounting plate 110. Specifically, the drive device 310 is detachably connected to the first mounting plate 110. Based on this, the structural rationality of the guide assembly 500 is improved, thereby improving the motion stability of the guide shaft 510 and further improving the reliability of the light-shielding device 1000.

[0052] Reference Figure 3 and Figure 4As shown, in this embodiment of the present invention, a first buffer member 530 is provided between the first connecting member 320 and the guide member 520. The first buffer member 530 is connected to the guide member 520 and extends around the guide hole 521. It can be understood that when the driving device 310 drives the first connecting member 320 downward to the first buffer member 530, the first connecting member 320 abuts against the first buffer member 530 to buffer the impact force of the downward movement of the first connecting member 320, reducing the risk of damage to the first connecting member 320, thereby improving the reliability and stability of the light-shielding device 1000. In this embodiment, the first buffer member 530 can be a rubber part or a spring; this embodiment does not limit the type of buffer member.

[0053] Reference Figure 3 and Figure 4 As shown, in this embodiment of the present invention, the driving device 310 includes a driving shaft 311. Specifically, the driving shaft 311 extends along the height direction of the bracket 100 and is configured to move along the height direction of the bracket 100. In this embodiment, the driving assembly 300 also includes a connecting rod 340 and a limiting member 350. The connecting rod 340 and the limiting member 350 are respectively connected to the driving shaft 311. Specifically, the first connecting member 320 is provided with a connecting hole 321, which extends through the first connecting member 320 along the height direction of the bracket 100. The connecting rod 340 passes through the connecting hole 321, and the driving shaft 311 passes through the connecting rod 340 and is connected to the limiting member 350.

[0054] Reference Figure 4 As shown, in this embodiment, the connecting rod 340 is located below the first connecting member 320, a second buffer member 360 is provided between the connecting rod 340 and the first connecting member 320, a limiting member 350 is located above the first connecting member 320, and a third buffer member 370 is provided between the limiting member 350 and the first connecting member 320. Specifically, the lower end of the connecting rod 340 is provided with an abutting portion, the lower end of the second buffer member 360 abuts against the abutting portion, the lower end of the second buffer member 360 abuts against the first connecting member 320, the lower end of the third buffer member 370 abuts against the first connecting member 320, and the upper end of the third buffer member 370 abuts against the limiting member 350.

[0055] Understandably, when the drive shaft 311 drives the first connector 320 to move along the height direction of the bracket 100, the second buffer 360 and the third buffer 370 can buffer the inertial force of the first connector 320 moving up and down. Specifically, when the first connector 320 moves upward and stops at a certain position, the first connector 320 presses against the third buffer 370 to buffer the inertial force of the first connector 320 moving upward; when the first connector 320 moves downward and stops at a certain position, the first connector 320 presses against the second buffer 360 to buffer the inertial force of the first connector 320 moving downward.

[0056] Based on this, the risk of wear on the first connector 320 is reduced, and the reliability and stability of the drive assembly 300 are improved. In this embodiment, the second buffer 360 and the third buffer 370 can be buffered by rubber parts or springs, and this embodiment is not limited to either.

[0057] Reference Figure 2 , Figure 3 and Figure 5 As shown in this embodiment of the utility model, along the arrangement direction of the camera module 2100 and the bracket 100, a limiting block 430 is provided at the end of the slide rail 410. The limiting block 430 is fixedly connected to the bracket 100. It can be understood that when the slider 420 moves along the slide rail 410 to the end of the slide rail 410, the limiting block 430 abuts against the slider 420, thereby preventing the slider 420 from disengaging from the slide groove 421, thus improving the structural rationality and reliability of the light-shielding device 1000.

[0058] Reference Figure 1 and Figure 2 As shown, this utility model embodiment also proposes a camera testing device 2000, including a camera module 2100, a lamp body 2200 and a light shielding device 1000 as described in the above embodiment. The camera module 2100 and the lamp body 2200 are arranged at intervals along the height direction of the light shielding device 1000. In this embodiment, the light-shielding device 1000 consists of a bracket 100 disposed on one side of the camera module 2100, the bracket 100 having two slide rails 410 spaced apart, the slide rails 410 extending along the arrangement direction of the camera module 2100 and the bracket 100; two sliders 420 slidably connected to the two slide rails 410 in a one-to-one correspondence; a light-shielding plate 200 disposed on one side of the camera module 2100 and located between the two sliders 420, the two ends of the light-shielding plate 200 being connected to the two sliders 420 in a one-to-one correspondence; and a driving assembly 300 mounted on the bracket 100 and connected to the light-shielding plate 200, the driving assembly 300 being configured to drive the light-shielding plate 200 to move along the arrangement direction of the camera module 2100 and the bracket 100.

[0059] Based on this, when the drive assembly 300 drives the light shield 200 to move along the arrangement direction of the camera module 2100 and the bracket 100, the sliders 420 at both ends of the light shield 200 move along the slide rail 410, so that the two ends of the light shield 200 move synchronously, reducing the risk of the light shield 200 tilting, thereby improving the movement stability of the light shield 200, which in turn improves the stability and reliability of the light shielding device 1000, further improves the accuracy of the test results, and further improves the reliability and stability of the camera test equipment 2000, extending the service life of the camera test equipment 2000.
