[0002] A webcam, also known as a computer camera, computer eye, or electronic eye, is a video input device widely used in video conferencing, telemedicine, and real-time monitoring. Webcams generally have basic functions such as video recording / transmission and still image capture. They work by capturing images through a lens, which are then processed by the webcam's internal photosensitive circuitry and control components, converting the images into digital signals that a computer can recognize. These signals are then input to a computer via a parallel port or USB connection, where software reconstructs the image.

Detailed Implementation

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] This utility model embodiment provides a fixture for testing the stability of a camera, see [link to relevant documentation]. Figure 1 and combined Figures 2 to 4 , Figure 1 This is a schematic diagram of a fixture used for testing the stability of a camera. The fixture includes: a base 1, a support 2, a guide post 3, a gripper 4, a lower pressure plate 5, a first elastic element 6, a second elastic element 7, and a probe 8.

[0050] The upper end face of the base 1 is provided with a first mounting port 11 for mounting the bearing seat 2;

[0051] The upper end face of the support 2 is provided with a second mounting port 21 for mounting a camera;

[0052] The gripper 4 is disposed on the support 2;

[0053] The lower pressure plate 5 is a ring structure. The lower pressure plate 5 is sleeved on the bearing seat 2. The lower pressure plate 5 can move between a first position and a second position. The first position is higher than the second position. When the lower pressure plate 5 moves from the first position to the second position, it is used to drive the gripper 4 to open.

[0054] The guide post 3 is vertically mounted on the upper surface of the base 1;

[0055] The lower pressure plate 5 has a through hole for sliding cooperation with the guide post 3;

[0056] The first elastic element 6 is disposed between the lower pressure plate 5 and the base 1. The first elastic element 6 is used to drive the lower pressure plate 5 to rise to the first position.

[0057] The second elastic element 7 is disposed between the bearing seat 2 and the gripper 4. The second elastic element 7 is used to drive the gripper 4 to clamp the camera when the lower pressure plate 5 rises to the first position.

[0058] It should be noted that the camera includes a camera body and a camera base 1. The gripper 4 of this application is mainly used to clamp the camera body. Since the first elastic member 6 is disposed between the lower pressure plate 5 and the base 1, when the lower pressure plate 5 is pressed down to the second position, the elastic restoring force provided by the first elastic member 6 can provide upward force for the lower pressure plate 5, that is, it can make the lower pressure plate 5 rise from the second position to the first position. Since the probe 8 is disposed on the lower pressure plate 5, when the lower pressure plate 5 rises from the second position to the first position, the probe 8 can contact the camera to achieve connection with the camera. At the same time, the gripper 4 clamps the camera body under the action of the second elastic member 7. Since the second elastic member 7 can provide a continuous elastic restoring force for the gripper 4, the gripper 4 can continuously and stably clamp and fix the camera body.

[0059] It should also be noted that the size of a camera is usually determined by the size of the camera body. Therefore, this application uses the clamp 4 to fix the camera body, which can meet the needs of fixing cameras of different sizes.

[0060] It is worth noting that when the pressure plate 5 moves from the first position to the second position, it is used to drive the gripper 4 to open, at which time the camera can be taken out from the second mounting port 21 or put into the second mounting port 21.

[0061] In this embodiment of the invention, a support 2 is disposed on the upper surface of a base 1, and an installation port 21 for mounting a camera is opened on the upper surface of the support 2. A gripper 4 is disposed on the support 2. A lower pressure plate 5 has an annular structure and is sleeved on the support 2. The lower pressure plate 5 can move between a first position and a second position. A guide post 3 is vertically disposed on the upper surface of the base 1. The lower pressure plate 5 has a through hole for sliding cooperation with the guide post 3. A first elastic element 6 is disposed between the lower pressure plate 5 and the base 1. The first elastic element 6 is used to drive the lower pressure plate 5 to rise to the first position. A second elastic element 7 is disposed between the support 2 and the gripper 4. The second elastic element 7 is used to drive the gripper 4 to clamp the camera when the lower pressure plate 5 rises to the first position. With the above-disclosed tooling for testing the stability of a camera, since the gripper 4 of this application can continuously clamp and fix the camera body under the elastic restoring force provided by the second elastic element 7, the tooling of this application can effectively and firmly fix cameras of different heights and sizes, ensuring the accuracy of the camera stability test.

[0062] Specifically, the gripper 4 includes: a first clamping plate 41 and a second clamping plate 42;

[0063] The support base 2 has a first mounting groove for mounting the first clamping plate 41 and a second mounting groove for mounting the second clamping plate 42 on opposite sides;

[0064] The first end of the first clamping plate 41 and the first end of the second clamping plate 42 are used to clamp the camera;

[0065] A second elastic element 7 is provided between the second end of the first clamping plate 41 and the bearing seat 2, and between the second end of the second clamping plate 42 and the bearing seat 2.

[0066] The first clamping plate 41 is provided with a first hinge point that is hinged to one side of the bearing seat 2, wherein the first hinge point is located between the first end of the first clamping plate 41 and the second end of the first clamping plate 41.

[0067] The second clamping plate 42 is provided with a second hinge point that is hinged to the other side of the bearing seat 2, wherein the second hinge point is located between the first end of the second clamping plate 42 and the second end of the second clamping plate 42.

[0068] It should be noted that by providing a first hinge point on the first clamping plate 41 that is hinged to one side of the support seat 2, and setting the first hinge point between the first end and the second end of the first clamping plate 41, and by providing a second hinge point on the second clamping plate 42 that is hinged to the other side of the support seat 2, and setting the second hinge point between the first end and the second end of the second clamping plate 42, when the pressure plate 5 descends from the first position to the second position, it can drive the first clamping plate 41 and the second clamping plate 42 to rotate, so that the first end of the first clamping plate 41 and the first end of the second clamping plate 42 move away from the camera. When the pressure plate 5 rises from the second position to the first position, the first clamping plate 41 and the second clamping plate 42 rotate under the elastic restoring force provided by the second elastic member 7, so that the first end of the first clamping plate 41 and the first end of the second clamping plate 42 continuously clamp and fix the camera.

[0069] It should also be noted that the number of the second elastic element 7 needs to be selected based on the elasticity of the second elastic element 7 and the clamping force of the first clamping plate 41 and the second clamping plate 42 on the camera. This application does not make a specific limit on the number of the second elastic element 7.

[0070] It is worth noting that the first clamping plate 41 and the second clamping plate 42 can be rotatably connected to the bearing seat 2 by means of hinges or by means of a rotating shaft. Those skilled in the art can choose according to their needs.

[0071] Furthermore, the first end of the first clamping plate 41 is bent toward the bearing seat 2 to form a first bent portion 411;

[0072] The first end of the second clamping plate 42 is bent toward the bearing seat 2 to form a second bent part 421;

[0073] The second end of the first clamping plate 41 is bent away from the bearing seat 2 to form a third bending part 412;

[0074] The second end of the second clamping plate 42 is bent away from the bearing seat 2 to form the fourth bend 422.

[0075] It should be noted that bending the first end of the first clamping plate 41 toward the support seat 2 to form the first bending portion 411, and bending the first end of the second clamping plate 42 toward the support seat 2 to form the second bending portion 421, can make the tooling for testing the stability of the camera more compact.

[0076] The second end of the first clamping plate 41 is bent away from the support seat 2 to form a third bend 412, and the second end of the second clamping plate 42 is bent away from the support seat 2 to form a fourth bend 422. As the pressure plate 5 moves down from the first position to the second position, the descent of the pressure plate 5 will cause the second end of the first clamping plate 41 and the second end of the second clamping plate 42 to approach the support seat 2. At the same time, it will drive the first end of the first clamping plate 41 and the first end of the second clamping plate 42 away from the support seat 2, that is, the gripper 4 opens to facilitate the removal or insertion of the camera.

[0077] It should also be noted that the first bending portion 411 and the second bending portion 421 can be formed by bending or by welding, and those skilled in the art can choose according to their needs.

[0078] Furthermore, the first end of the first clamping plate 41 and the first end of the second clamping plate 42 are both arc-shaped slot structures that cooperate with the camera.

[0079] It should be noted that by setting the first end of the first clamping plate 41 and the first end of the second clamping plate 42 as arc-shaped slot structures that cooperate with the camera, the camera can be further fixed and the camera can be accurately contacted with the probe 8.

[0080] Furthermore, the number of the first elastic element 6 is multiple;

[0081] Multiple first elastic elements 6 are arranged around the bearing seat 2.

[0082] It should be noted that by setting multiple first elastic elements 6 and arranging multiple first elastic elements 6 around the bearing seat 2, the pressure plate 5 can be subjected to more uniform force, thereby making the pressure plate 5 rise more smoothly from the second position to the first position.

[0083] Specifically, there are multiple guide pillars 3;

[0084] Multiple guide columns 3 are arranged around the bearing seat 2;

[0085] The lower pressure plate 5 has multiple through holes, each of which corresponds to a guide post 3.

[0086] It should be noted that by setting the number of guide posts 3 to multiple and arranging the multiple guide posts 3 around the bearing seat 2, and by opening multiple through holes in the lower pressure plate 5 and making the multiple through holes correspond one-to-one with the multiple guide posts 3, the accuracy of the lower pressure plate 5 when rising or falling can be further ensured through the cooperation of the multiple guide posts 3 and the multiple through holes, and the tilting of the lower pressure plate 5 when rising or falling can be avoided.

[0087] Specifically, the second elastic element 7 and / or the first elastic element 6 are springs.

[0088] It should be noted that the first elastic element 6 and the second elastic element 7 can be the same spring, or different springs, or the same or different spring sheets, or other elastic elements that can produce elastic deformation under external force. Those skilled in the art can choose according to their needs.

[0089] Furthermore, the tooling used for testing the stability of the camera also includes: a lifting and height limiting component 10;

[0090] The lifting height limiting component 10 is disposed on the base 1, and the lifting height limiting component 10 is used to limit the height of the lower pressure plate 5 from rising to a preset height.

[0091] It should be noted that the preset height is the first position of this application. Those skilled in the art can adjust the specific height of the first position by using the lifting and height limiting component 10 as needed.

[0092] Preferably, the lifting height limiting component 10 includes a rod and a limiting nut;

[0093] The rod is vertically mounted on the base 1;

[0094] The lower pressure plate 5 has a movable hole for the rod to pass through;

[0095] The upper end of the rod is provided with an external thread that mates with the limit nut.

[0096] It should be noted that the diameter of the limiting nut is larger than the diameter of the movable hole, so the lower pressure plate 5 can only move between the limiting nut and the base 1, that is, between the first position and the second position of this application.

[0097] Furthermore, the fixture used for testing camera stability also includes: probe 8;

[0098] The upper part of the base 1 has a movable groove;

[0099] The probe 8 is positioned on the lower pressure plate 5, and the probe 8 can contact the camera when the lower pressure plate 5 rises to the first position.

[0100] It should be noted that,

[0101] Furthermore, the fixture used for testing the stability of the camera also includes: side ears 12 disposed on both sides of the base 1;

[0102] The side ear 12 has a positioning hole 13 for positioning.

[0103] It should be noted that by setting side ears 12 on both sides of the base 1 and opening positioning holes 13 for positioning in the side ears 12, it is convenient for staff to accurately install the tooling used for testing the stability of the camera on the workbench.

[0104] Furthermore, the tooling used for testing the stability of the camera also includes: a flexible positioner 9;

[0105] The side ear 12 has a fixing hole through which the flexible positioner 9 is tightened.

[0106] It should be noted that by providing a fixing hole for the flexible positioner 9 to be tightened through the side ear 12, the fixture used for testing the stability of the camera can be fixed by the flexible positioner 9, so as to avoid shaking during the camera test and affecting the accuracy of the test.

[0107] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
