Detailed implementation manners

[0025] To make the objectives, features, and advantages of the present disclosure more obvious and understandable, the following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present disclosure.

[0026] In the existing notebook computer structure, it generally includes a display end and a system end. Among them, the display end is the side with the display screen, and the system end is the side with the keyboard. Generally, the display end and the system end can be rotatably opened and closed. Among them, the system end includes an upper housing and a lower housing, and the keyboard is installed on the upper housing. On the front side surrounded by the upper housing and the lower housing, that is, the side where the user operates, there is a front frame. The switch for starting or closing the video function is the camera shutter. Exemplarily, the camera shutter is located in the front frame of the notebook computer.

[0027] In the test of the switching force of the camera shutter, there are the following problems: the convex block of the test fixture is very small, and it is difficult to align visually, which greatly affects the test efficiency; at the same time, the test machine and the test fixture are not parallel, resulting in interference between the camera shutter and the front frame of the notebook computer, increasing the friction force and affecting the test result of the switching force of the camera shutter.

[0028] To alleviate the above problems, referring to Figures 1 - 5 , the embodiments of the present disclosure provide a test fixture 001. When in use, the test fixture 001 is located on the front side of the notebook computer, that is, the front side of the front frame. The camera shutter is provided in the front frame, and the position to be measured is a positioning groove of the camera shutter. To facilitate the description of the positional relationship of each structure, the width direction of the notebook computer is defined as the first direction, the thickness direction of the notebook computer is defined as the second direction, and the length direction of the notebook computer is defined as the third direction.

[0029] The test fixture 001 of the embodiments of the present disclosure includes: a display member 5, a link member 4, a driving member 3, and a support unit. Among them, the driving member 3 is elastically connected to one side of the support unit along a first direction. The driving member 3 is connected to the display member 5 through the link member 4. At least a part of the structure of the link member 4 is drivingly connected to the driving member 3, so that the link member 4 can rotate following the rotation of the driving member 3. At least a part of the structure of the link member 4 extends along the first direction and the display member 5 is installed on the side close to the front frame. The display member 5 is elastically connected to at least a part of the structure of the link member 4 along a second direction. At the same time, the display member 5 can set two different display circuits as needed to display whether the positioning groove of the camera shutter is accurately inserted.

[0030] Considering the specific test scenario of the camera shutter switch force test, it is necessary to add a function of guiding the front frame to the test fixture 001. The test fixture 001 of the embodiments of the present disclosure further includes balance bars 6. The balance bars 6 are arranged in pairs. One end of each balance bar 6 can be installed on the same mounting surface of the driving member 3 and the support unit, and is elastically connected to the support unit along the first direction at the same time. The other end of each balance bar 6 can be used to abut against the front frame. Exemplarily, the surface of the support unit of the embodiments of the present disclosure for installing the driving member 3 is always parallel to the abutting surface of each balance bar 6 and the surface area of the front frame. In this way, regardless of whether the initial placement position of the front frame is parallel to the abutting surface of the balance bars 6 of the test fixture 001, during the process of the two balance bars 6 abutting against the front frame at the same time, they can push the support unit to be parallel to the front frame. In this way, it can be ensured that the display member 5 can probe into the positioning groove of the camera shutter within the allowable misinsertion range or near the positioning groove position.

[0031] Considering that the display member 5 can accurately probe into the positioning groove of the camera shutter, the support unit of the embodiments of the present disclosure includes a support outer shell 1 and a support inner shell 2. The support inner shell 2 is sleeved inside the support outer shell 1 and is elastically connected to the inner wall of the support outer shell 1 along the first direction. One end of each balance bar 6 is connected to the inner wall of the support inner shell 2 and extends out of the support inner shell 2 and the support outer shell 1 in sequence along the first direction. The driving member 3 is connected to the inner wall of the support inner shell 2, and the driving member 3 is located between the balance bars 6. Along the second direction, the display member 5 can elastically abut against the surface to be tested (the positioning groove of the camera shutter) of the test piece. In this way, the support inner shell 2 is directly connected to each balance bar 6, the driving member 3, and the link member 4, and the support inner shell 2 can also elastically move in the first direction relative to the support outer shell 1, which can ensure that when the two balance bars 6 face non-parallel abutting surfaces, the support inner shell 2 can be moved along with them to the planar state with the front frame. Further, the display member 5 can rotate along the circumferential direction of the driving member 3 under the drive of the driving member 3 through the link member 4, and further ensure that the display member 5 follows the circumferential movement, so that it can move the convex surface on the camera shutter to the positioning groove position and ensure the accuracy of the switch force test.

[0032] Applying the test fixture 001 of the embodiments of the present disclosure, the display member 5 can contact the surface to be tested at different height positions (which can be the convex surface around the positioning groove of the camera shutter). The display member 5 is used to judge whether the surface to be tested and the test fixture 001 are arranged in parallel by displaying different color lights. Exemplarily, the red indicator light is used to display the position where the positioning groove of the camera shutter is not contacted, and the green indicator light is used to display the position where the positioning groove of the camera shutter is contacted. Further, along the first direction, the display member 5 is drivingly connected to the driving member 3 through the link member 4, so that the display member 5 can move along its circumferential direction, and further adapt to the abutment of the surface to be tested at different height positions.

[0033] Considering that the display member 5 can rotate along the circumferential direction of its plane through the link member 4, in the embodiments of the present disclosure, the rotation plane of the link member 4 is parallel to the rotation plane of the driving member 3, and the display member 5 extends out of the support housing 1. In this way, it can be ensured that the display member 5 can rotate in the preset distance position area relative to the end surface of the balance bar 6, and further ensure that the display member 5 abuts against the positioning groove of the camera shutter.

[0034] Specifically, in the embodiments of the present disclosure, the driving member 3 includes a motor 31 and an output shaft 32, the link member 4 includes a first rod portion 41 and a second rod portion 42. One end of the first rod portion 41 is drivingly connected to the output shaft 32, the other end of the first rod portion 41 is hinged to the second rod portion 42, and the second rod portion 42 drives the display member 5 to rotate synchronously. In this way, the motor 31 serves as a driving mechanism, drives the first rod portion 41 to rotate through the output shaft 32. Under the hinge setting of the second rod portion 42 and the first rod portion 41, the second rod portion 42 can rotate around the hinge of the first rod portion 41. Further, the link member 4 further includes a housing sub-portion 43. Along the first direction, the second rod portion 42 is fixedly connected to the tail end of the housing sub-portion 43, or the second rod portion 42 is formed at the tail end of the housing sub-portion 43; at the same time, the housing sub-portion 43 is configured as a structure extending along the third direction. Along the second direction, at least a part of the display member 5 is embedded in the head end of the housing sub-portion 43. In this way, the display member 5 can sequentially follow the housing sub-portion 43, the second rod portion 42 and the first rod portion 41 to rotate synchronously with the output shaft 32 of the motor 31.

[0035] Considering the specific installation scheme of the display member 5 and the housing sub-portion 43, along the second direction, the housing sub-portion 43 is provided with a groove, the opening of the groove faces downward, the display member 5 includes a convex column 51 and an indicator light 52, the convex column 51 is located below the groove, and the indicator light 52 is located above the groove; specifically, the indicator light 52 is installed on the top surface of the housing sub-portion 43, the convex column 51 is elastically connected to the top wall of the groove, and the bottom surface of the convex column 51 is used to abut against the surface to be tested; specifically, the bottom surface of the convex column 51 can elastically abut against the bottom surface of the positioning groove of the camera shutter.

[0036] Further elaboration will be made on how the display member 5 shows whether it is in contact with the positioning groove of the camera shutter through the illumination of different indicator lights 52 during the movement. In the embodiment of the present disclosure, there are a first displacement contact point and a second displacement contact point higher than the first displacement contact point between the top wall of the groove and the top surface of the convex post 51; when the convex post 51 moves to the first displacement contact point, the circuit of the green indicating portion 522 can be conducted, and the green indicator light in the indicator light 52 lights up; when the convex post 51 moves to the second displacement contact point, the circuit of the red indicating portion 521 can be conducted, and the red indicator light in the indicator light 52 lights up. It should be noted that the circuit of the red indicating portion 521 and the circuit of the green indicating portion 522 are independently arranged.

[0037] Considering the specific structural features of the support housing 1, in the embodiment of the present disclosure, a convex hole is provided on one side of the support housing 1 for the protrusion of each balance rod 6 and the housing sub - part 43; guiding channels for each balance rod 6 are formed along the first direction at the two ear positions of the convex hole. In this way, the balance rod 6 can be prevented from shaking in a direction away from the link member 4.

[0038] Combined with the above - mentioned specific scheme, further, at least part of the structures of the first rod portion 41, the second rod portion 42 and the housing sub - part 43 are located inside the support inner housing 2. In this way, the support inner housing 2 can ensure the stable support of the first rod portion 41, the second rod portion 42 and the housing sub - part 43.

[0039] Considering the elastic connection of the support inner housing 2 relative to the support housing 1 along the first direction, the test fixture 001 further includes a pair of first elastic members 7, and each first elastic member 7 is connected between the inner wall of the support housing 1 and the outer wall of the support inner housing 2 and is coaxially arranged with each balance rod 6 respectively. Considering the elastic connection of the convex post 51 with the housing sub - part 43 along the second direction, the test fixture 001 further includes a second elastic member 8, and the second elastic member 8 is connected between the housing sub - part 43 and the convex post 51.

[0040] In summary, for the test fixture 001 according to the embodiments of the present disclosure, the display member 5 is elastically abutted against the surface to be measured of the device under test, contacting the surfaces to be measured at different height positions. The display member 5 is used to determine whether the surface to be measured is parallel to the test fixture 001 by displaying lights of different colors. It can be understood that by displaying lights of different colors, it is determined whether the test fixture 001 of the present disclosure is aligned with the groove position on the camera shutter of the notebook computer, which can greatly improve the efficiency of the tester. In addition, when the notebook computer under test is not parallel to the test fixture 001, through the elastic abutment of the paired balance rods 6 against the front frame of the notebook computer under test, the support inner shell 2 can always be parallel to the front frame of the notebook computer under test, thereby ensuring that the display member 5 connected to the support inner shell 2 through the driving member 3 and the link member 4 will not interfere with or rub against the camera shutter structure provided on the front frame, further ensuring the structural accuracy of the camera shutter switch force test.
