Description

Technical Field

[0001] This invention relates to the field of visual field testing, and in particular to a visual field testing device for goggles. Background Technology

[0002] Currently, in testing the field of view performance of goggles, when testing the horizontal field of view, the goggles are first fixed to a head model, and the laser emitter remains stationary. By driving the head model to rotate horizontally, the laser emitted by the emitter is adapted to the rotation angle of the head model, thereby detecting the horizontal field of view boundary of the goggles. When testing the vertical field of view, the head model remains fixed, and the laser emitter is mounted on a bracket. By driving the bracket to revolve around the head model, the laser emitter is rotated vertically by 45 degrees to detect the vertical field of view boundary of the goggles. However, this testing method still has certain shortcomings: The laser emitter and the head model have a certain installation and testing distance, resulting in a relatively long laser emitter support arm. This can easily lead to a small laser emitter support effect. When the laser emitter rotates to 45 degrees and stops, the long support arm amplifies the inertial effect, causing a tiny fluctuation of 0.1-0.3 degrees that is difficult to detect with the naked eye. This fluctuation cannot be stabilized immediately, requiring waiting for the fluctuation to stop before data recording. This increases the testing time for a single pair of goggles, leading to a decrease in the overall testing efficiency of large batches of goggles. Furthermore, the fluctuation caused by the support arm can cause the laser emission axis to deviate from the center of the head model's pupil. Even after the fluctuation stops, the deviated laser may only move from the center of the pupil to the edge, or directly illuminate the edge distortion area of ​​the goggle lens. The former will cause a slight attenuation of the light intensity received by the sensor, mistakenly identifying the slight fluctuation of normal light transmission as slight obstruction by the goggle. The latter will mistakenly equate the light attenuation caused by lens distortion with obstruction of the field of view boundary, leading to false detections. Summary of the Invention

[0003] In view of the problem in the above or existing technologies that the laser emitter is prone to slight fluctuations due to inertia and other factors at the moment of stopping rotation, which affects the test accuracy, this invention is proposed.

[0004] Therefore, the purpose of this invention is to provide a goggle field of vision testing device.

A positioning and locking component is provided between the laser component and the guide frame. The positioning and locking component is used to automatically position the rotation angle of the laser component and automatically lock the laser component on the guide frame when testing the up and down visibility angle of the goggles. A control component is provided between the positioning and locking component and the laser emitter bracket. The control component is slidably connected to the guide frame and is used to drive the positioning and locking component.

[0006] As a preferred embodiment of the goggle field of view testing device of the present invention, the guide frame is provided with two guide grooves that are symmetrical to each other along the translation direction of the translation stage. The laser emitting module is slidably connected to the guide groove on the side closer to the head mold's field of view, and the laser emitter bracket is slidably connected to the guide groove on the side away from the head mold's field of view, so that the guide grooves guide and strengthen the laser emitter bracket.

[0007] As a preferred embodiment of the goggle field of view testing device of the present invention, the laser component includes a side slide groove formed in the inner wall of the guide slide groove and penetrating the guide frame, a connecting plate is slidably installed in the side slide groove through an L-shaped plate, and a laser emitter is fixedly installed on the connecting plate.

[0008] As a preferred embodiment of the goggle field of view testing device of the present invention, the positioning and locking assembly includes a mounting box slidably installed in a guide groove, and a movable frame is slidably installed in the mounting box.

[0009] As a preferred embodiment of the goggle field of view testing device of the present invention, the movable frame is composed of a U-shaped segment and C-shaped segments integrally formed at both ends of the U-shaped segment. A spring telescopic rod is fixedly installed inside the U-shaped segment, and the telescopic end of the spring telescopic rod slides through the U-shaped segment. A locking groove is provided in the guide groove.

[0010] As a preferred embodiment of the goggle field of view testing device of the present invention, the locking groove is provided in three parts, and the included angle between two adjacent locking grooves is 45 degrees.

[0011] As a preferred embodiment of the goggle field of view testing device of the present invention, the control component includes two actuating members rotatably installed in the mounting box and symmetrical to each other along the moving direction of the moving frame. The actuating members are slidably connected in the C-shaped section at one end near the inner wall of the mounting box. The mounting box is slidably installed with an actuating frame, and the two actuating members are slidably connected to the actuating frame at the adjacent ends.

[0015] The beneficial effects of the goggle field of view testing device of the present invention are as follows: In this application, by symmetrically extending the laser emitter bracket and using symmetrically arranged double guide grooves on the guide frame to form a sliding fit with the laser emission module and the laser emitter bracket respectively, a double support constraint structure is constructed. This directly avoids the cantilever effect of the long support arm and initially prevents the laser component from shifting due to inertia when it stops rotating, providing a stable structural foundation for subsequent light detection. Furthermore, the positioning and locking component can achieve instantaneous positioning and locking of the laser component at the test angle through the automatic engagement of the spring telescopic rod and the preset angle locking groove. This further enhances the stability of the laser component when it stops at the positioning level, forming multiple guarantees of double constraint and automatic locking. This avoids the test deviation problem caused by laser shift and eliminates the redundant time of waiting for the fluctuation to stop, significantly shortening the test time of a single pair of goggles and effectively improving the overall testing efficiency of large batches of goggles. At the same time, the entire process can be completed without manual intervention for unlocking and angle switching. Attached Figure Description

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1-9This embodiment provides a goggle field of view testing device, which can eliminate the redundant time of waiting for fluctuations to stop and significantly shorten the testing time of a single pair of goggles. It includes: a body 1; a rotatable lifting platform 2 on the body 1, a translation platform 3 for fixing a head mold 4 slidably mounted on the lifting platform 2; a guide frame 5 and a fixing seat 7 fixedly mounted on the body 1, a laser emitter bracket 8 rotatably mounted on the fixing seat 7; a laser emitting module 6 for emitting lasers to the head mold 4 on the guide frame 5; the laser emitting module 6 includes a laser component 61 slidably mounted on the guide frame 5, a positioning and locking component 62 between the laser component 61 and the guide frame 5, the positioning and locking component 62 automatically positioning the rotation angle of the laser component 61 and automatically locking the laser component 61 onto the guide frame 5 when testing the upper and lower visual angles of the goggles; a control component 63 between the positioning and locking component 62 and the laser emitter bracket 8, the control component 63 being slidably connected to the guide frame 5 and used to drive the positioning and locking component 62.

[0029] It should be noted that the rotatable lifting platform 2 is a load-bearing platform with rotation and lifting functions, specifically a scissor lift platform 2, used to adjust the height and horizontal angle of the head mold 4; the translation platform 3 is a loading platform that slides along a straight line, specifically a lead screw slide platform 3, used to fix the head mold 4 and adjust the horizontal position of the head mold 4 to ensure that the eyes of the head mold 4 are aligned with the laser emitter 613; the lifting platform 2, the translation platform 3 and the laser emitter bracket 8 are all controlled by their respective independent external power supplies; the working principles of the above-mentioned lifting platform 2, translation platform 3 and laser emitter bracket 8 are all existing technologies, and therefore will not be described in detail in this application.

[0030] The guide frame 5 is made of aluminum alloy profile to form a sliding groove, which is used to guide the movement trajectory of the laser component 61. The positioning and locking component 62 has angle positioning and mechanical locking functions, which is used to automatically fix and lock the laser component 61 at a set angle. The control component 63 is used to convert the rotation of the laser emitter bracket 8 into the drive of the positioning and locking component 62.

[0031] A high-precision photoelectric sensor is embedded at the center of the simulated pupil of the head mold 4, precisely aligned with the emission axis of the laser emitter 613. A silicon photodiode sensor, preferably model S1226-8BQ, is adapted to the 650nm wavelength semiconductor laser of the laser emitter 613. The sensor is connected to an external host computer system via a wire embedded inside the head mold 4. The sensor is detachably fixed to the head mold 4, facilitating the replacement of sensors with different sensitivities according to different goggle testing standards. Simultaneously, the sensor's sensing surface is flush with the curved surface of the simulated eyeball of the head mold 4, ensuring that the laser penetrates the goggle and strikes the sensor perpendicularly, avoiding light intensity detection errors caused by incident angle deviations. The aforementioned laser emitter 613 and photoelectric sensor are existing technologies and will not be described in detail in this application.

[0032] Reference Figures 2-9 The guide frame 5 has two guide grooves 51 that are symmetrical to each other along the translation direction of the translation stage 3. The laser emission module 6 is slidably connected to the guide groove 51 on the side closer to the field of view of the head mold 4, and the laser emitter bracket 8 is slidably connected to the guide groove 51 on the side away from the field of view of the head mold 4, so that the guide groove 51 guides and strengthens the laser emitter bracket 8.

[0033] It should be noted that the guide groove 51 is a sliding track set on the guide frame 5, used to constrain the movement trajectory of the laser emitting module 6 and the laser emitter support 8. The two guide grooves 51 of the guide frame 5 form a sliding engagement with the laser emitting module 6 and the laser emitter support 8, respectively. The guide groove 51 on the side closer to the head mold 4 bears the rotational movement of the laser emitting module 6, and due to the engagement relationship between the laser emitting module 6 and the laser emitter support 8, it also provides guidance for the laser emitter support 8. The guide groove 51 on the side farther from the head mold 4 forms a double guidance constraint with the laser emitter support 8. When the laser emitter support 8 drives the laser emitting module 6 to adjust its angle, the symmetrical layout of the guide grooves 51 on both sides forms a balanced support structure, ensuring that the laser emitter support 8 is always in a double support state during movement, thus improving the stability of the laser emitter support 8.

[0034] Reference Figures 2-9 The laser component 61 includes a side slide groove 614 formed in the inner wall of the guide slide groove 51 and passing through the guide frame 5. A connecting plate 612 is slidably installed in the side slide groove 614 via an L-shaped plate 611. A laser emitter 613 is fixedly installed on the side of the connecting plate 612 near the field of view of the head mold 4.

[0035] It should be noted that the side sliding groove 614 provides a sliding path for the L-shaped plate 611, ensuring that the laser assembly 61 moves along a preset trajectory. The L-shaped plate 611 is a metal plate with a right-angle bend structure, specifically made of aluminum alloy. Its shorter section slides in conjunction with the side sliding groove 614, while its longer section is fixedly connected to the connecting plate 612, used to constrain the movement direction of the laser emitter 613 onto the guide frame 5. The connecting plate 612 is used to support the laser emitter 613 and transmit the sliding driving force; the laser emitter 613 is a semiconductor laser, and its emission axis is aligned with the center of the pupil of the head mold 4, used to project a test beam onto the goggles.

[0036] In practical use: During the horizontal field of vision test, the goggles to be tested are first fixed on the head mold 4, ensuring that the goggles fit the simulated facial contours of the head mold 4 to reproduce the actual wearing state. Then, the horizontal position of the head mold 4 is adjusted by sliding the translation platform 3 horizontally, while the lifting platform 2 adjusts the height of the head mold 4 through lifting movements, gradually calibrating the posture of the head mold 4 until the center of the simulated pupil of the head mold 4 is precisely aligned with the emission axis of the laser emitter 613. After calibration, the laser emitter 613 is activated and continuously emits laser light. The laser penetrates the goggles and is directed towards the photoelectric sensor at the pupil of the head mold 4. At this time, the lifting platform 2 is rotated by an external power supply, causing the head mold 4 to slowly rotate horizontally around the vertical axis. The sensor captures the light intensity after the laser penetrates the goggles in real time and transmits the data to an external host computer. As the head model 4 rotates, the light intensity detected by the photoelectric sensor gradually decreases as the edge of the goggles frame or lens gradually blocks the laser. When the lifting platform 2 rotates the head model 4 to a test angle of 105 degrees for the total horizontal field of view, if the host computer detects that the light intensity is never lower than the preset threshold for judging the field of view boundary, it is determined that the goggles are not blocked at the horizontal 105-degree angle, and the horizontal field of view in the corresponding direction meets the qualification requirements. After completing a single horizontal field of view test, the translation platform 3 is controlled by an external power supply to slide horizontally so that the center of the pupil of the other eye simulated by the head model 4 is precisely aligned with the emission axis of the laser emitter 613. Then the above test process is repeated. After the horizontal field of view tests of both eyes are completed, the lifting platform 2 drives the head model 4 to return to the initial position, completing the complete horizontal field of view test process.

[0037] During the vertical field-of-view test, the goggles are first fixed to the head mold 4. The initial position of the head mold 4 is calibrated using the translation stage 3 and the rotatable lifting stage 2, ensuring that the center of the pupil of the head mold 4 is aligned with the axis of the laser emitter 613. The head mold 4 is then kept in a fixed position. After the test is started, the laser emitter bracket 8 is driven to rotate by an external power supply, thereby causing the laser emission module 6 to slide along the guide groove 51 on the guide frame 5. The laser emission module 6 automatically locks after moving with the laser emitter bracket 8 to the vertical test angle. At the same time, during the rotation of the laser emission module 6, the laser emitter 613 emits a laser, and the photoelectric sensor at the head mold 4 holds... Continue to detect the light intensity; when the laser emitting module 6 rotates 45 degrees and locks, the photoelectric sensor at the head mold 4 continuously detects the light intensity. If the intensity is not lower than the judgment threshold, it is determined that the goggles are not blocked at the 45-degree angle and the field of view in the corresponding direction meets the qualification requirements. After the 45-degree angle detection is completed, the control component 63 drives the positioning locking component 62 to unlock, and the laser emitter bracket 8 continues to move the laser emitting module 6 to another 45-degree test angle to repeat the above detection process. After both 45-degree angles are detected, the laser emitter bracket 8 drives the laser emitting module 6 to reset to the initial position, completing the complete upper and lower field of view test.

[0038] Reference Figures 2-9 The positioning and locking assembly 62 includes a mounting box 621 that is slidably installed in the guide slide groove 51. A movable frame 622 is slidably installed in the mounting box 621. The movable frame 622 is composed of a U-shaped section and C-shaped sections integrally formed at both ends of the U-shaped section. A spring telescopic rod 623 is fixedly installed in the U-shaped section. The telescopic end of the spring telescopic rod 623 slides through the U-shaped section. A locking groove 624 is provided in the guide slide groove 51. There are three locking grooves 624, and the included angle between two adjacent locking grooves 624 is 45 degrees.

[0039] It should be noted that the locking groove 624 is a positioning groove formed on the inner wall of the guide slide 51. It is used to fix the moving frame 622 after the telescopic end of the spring telescopic rod 623 is inserted, thereby achieving rapid positioning and locking of the laser emitter 613 angle. When the laser component 61 is rotated to the required 45-degree, 0-degree, or -45-degree position for testing, the telescopic end of the spring telescopic rod 623 is automatically inserted into the corresponding locking groove 624 under the action of the spring, achieving instantaneous positioning and locking of the laser component 61. The interval angle of the three locking grooves 624 matches the standard angle for testing the upper and lower field of view of the goggles, ensuring that the laser emitter 613 can be stably locked after rotating to each test angle, avoiding slight displacement due to inertia when sliding stops.

[0040] Reference Figures 2-9 The control component 63 includes two toggle members 631 that are rotatably installed in the mounting box 621 and symmetrical to each other along the moving direction of the moving frame 622. The end of the toggle member 631 near the inner wall of the mounting box 621 is slidably connected in the C-shaped section. The toggle frame 632 is slidably installed in the mounting box 621. The ends of the two toggle members 631 that are close to each other are slidably connected to the toggle frame 632.

[0041] Reference Figures 2-9 A reset spring 633 is fixedly installed between the fixed section of the toggle frame 632 and the spring telescopic rod 623. A pressure block 634 is fixedly installed on the side of the toggle frame 632 near the head mold 4. A square groove 630 is opened on the side of the laser emitter bracket 8 near the field of view of the head mold 4. A connecting block 635 is fixedly installed in the square groove 630. Two extrusion plates 636 that are symmetrical to each other along the length of the connecting block 635 are fixedly installed on the side of the connecting block 635 near the pressure block 634.

[0042] Reference Figures 2-9 The extrusion plate 636 and the pressure block 634 cooperate with each other, and the mating surfaces of the extrusion plate 636 and the pressure block 634 are both inclined surfaces. A reset spring 637 is fixedly installed between the extrusion plate 636 and the mounting box 621. A limiting rod 638 that slides through the mounting box 621 is fixedly installed on the side of the C-shaped section near the head mold 4. The ends of the two limiting rods 638 are jointly installed with a limiting frame 639, and the limiting frame 639 is slidably sleeved on the outside of the pressure block 634.

[0043] It should be noted that the first reset spring 633 is used to provide a restoring force to the actuating frame 632 after the pressure block 634 is disengaged from the action of the pressing plate 636; the second reset spring 637 is used to restore the pressing plate 636 to its initial position after the positioning lock is released.

[0044] In practical use, when calibration is complete, the telescopic end of the spring telescopic rod 623 is inserted into the locking groove 624 located in the middle (0 degrees) to achieve calibration. When the laser assembly 61 rotates under the drive of the laser emitter bracket 8 to perform up and down angle tests, firstly, the telescopic end of the spring telescopic rod 623 is inserted into the locking groove 624 to form a lock. Therefore, as the laser emitter bracket 8 rotates, it will drive the connecting block 635 to move the pressing plate 636 towards the side closer to the pressure block 634. The reset springs 637 on both sides of the mounting box 621 are compressed and stretched to store energy. Then, the pressing plate 636 gradually presses the pressure block 634. After being pressed, the 34 slides towards the side closer to the mounting box 621. The pressed block 634 then drives the connected actuating frame 632 to move, while compressing the first reset spring 633. During the movement of the actuating frame 632, it drives the two actuating parts 631 slidably connected to it to deflect around their own axis. The end of the actuating part 631 near the C-shaped section of the moving frame 622 slides accordingly, pushing the moving frame 622 to move away from the inner wall of the guide slide groove 51. Finally, the telescopic end of the spring telescopic rod 623 disengages from the locking groove 624, completing the unlocking. At the same time as the unlocking is completed, the second reset spring 637 resets, driving the mounting box 621 to reset and be positioned in the middle of the two L-shaped plates 611.

[0045] Then, as the laser emitter bracket 8 continues to rotate, it drives the mounting box 621 to rotate along the guide groove 51. This, in turn, causes the laser emitter 613 to move synchronously via the L-shaped plate 611 and the connecting plate 612. During testing, when the spring telescopic rod 623 moves to the 45-degree locking groove 624, the locking groove 624 aligns perfectly with the telescopic end of the spring telescopic rod 623. The spring telescopic rod 623, relying on its own elasticity, pushes the telescopic end to instantly embed into the corresponding locking groove 624. This mechanical engagement achieves relative fixation between the moving frame 622 and the guide frame 5, thus ensuring the laser emitter 613 moves synchronously. While completing the 45-degree angle positioning, it automatically locks the laser emitter 613, directly and stably locking the laser component 61 at the current angle. This prevents the laser component 61 from shifting due to the inertia of the laser emitter bracket 8 when it stops rotating, providing a stable angular reference for the subsequent photoelectric sensor to detect the light intensity. This ensures that the laser emission direction is always accurately aligned with the center of the pupil of the head mold 4 during the test. After a single up and down angle test is completed, the laser emitter bracket 8 is rotated in the opposite direction, and the above unlocking and rotation operations are repeated to perform another 45-degree angle test.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
