[0002] A vision screener is a device used to test the refractive power of children and adults' eyes. It is an important device for large-scale, rapid vision screening in hospital departments, grassroots communities, and schools. The vision screener has a vision screening system, which generally includes: an optical path module for collecting reflected infrared light from a fixed pupil area; a sensing module for converting the reflected infrared light obtained by the optical path module into image information of the fixed pupil area; a light source module for providing a light source; and an AI intelligent pupil recognition unit for detecting and identifying the image information of the fixed pupil area obtained by the sensing module. After investigation, the public (announcement) number: 202410734481.2 discloses a self-service intelligent vision screening and testing device, which has "an auxiliary seat is set up inside the isolation box on the base of the equipment using a telescopic support rod, a hydraulic push rod, a moving block and a driving screw, and under the action of the adjusting rod, the moving rod, the wedge block and the elastic component are coordinated to complete the linkage control of the deflection sealing plate, the vision tester and the auxiliary seat. When the hydraulic push rod pushes the auxiliary seat in and out of the isolation box, the vision tester is synchronously controlled to enter and exit the installation cavity on the side wall of the L-shaped column, so that the user can complete the height and other data detection and then sit on the auxiliary seat to perform the vision test. While realizing the linkage use of the vision tester and the auxiliary seat, the isolation protection of the vision tester is guaranteed, and the multiple functions such as vision detection, height and comfort and safety are integrated into one, fully meeting the user's use needs and greatly improving the practicality of the equipment" and other technical effects; However, in actual use, it was found that after one use, the isolation box and its internal connectors needed to be retracted and opened again when the user changed, which was not convenient to operate. In addition, the isolation box needed to provide a movable opening at the top to open the internal components, resulting in poor internal protection. Secondly, the deflection seal plate's drive structure is curved, which may cause jamming during actual use. Furthermore, the smart touch display is always exposed, making it difficult to protect. To solve the above problems, this application proposes a self-service vision detection device and method. Summary of the Invention

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] like Figure 1 - Figure 7 As shown: A self-service vision testing device includes a body 1, which includes a base 11 and an L-shaped column 12 fixed to the base 11. A detector 13 and an intelligent touch display 14 are installed on the L-shaped column 12. The detector 13 and the L-shaped column 12 are directly connected by bolts or snaps. An auxiliary stool 2 is hinged on the L-shaped column 12. The auxiliary stool 2 can switch back and forth between an upward vertical state and a horizontal state. The upward vertical state is in a stored state, and the horizontal state is in an expanded state, forming a sitting area. Furthermore, two guard plates 3 for protecting the detector 13 and the smart touch display 14 are hinged on the side of the L-shaped column 12. A sponge frame 31 is provided on the side of the guard plate 3 close to the detector 13 and the smart touch display 14. The sponge frame 31 is bonded to the guard plate 3. When the guard plate 3 is closed, the sponge frame 31 forms a protective cover around the detector 13 and the smart touch display 14. The sponge frame 31 is attached to the base 11 and a protective space is formed between the sponge frame 3 and the guard plate 3. In order to avoid unnecessary wear, the guard plate 3 in the protective state does not directly contact the base 11.

[0018] Furthermore, the auxiliary stool 2 and the guard plate 3 are synchronously locked by the latch 4 after being closed, and are synchronously locked by the lock pin 6 after being opened. The latch 4 in this embodiment cooperates with the connecting ear 33 to lock the auxiliary stool 2 and the guard plate 3, and the insertion between the lock pin 6 and the annular groove 51 has the characteristics of convenient operation and good linkage, while ensuring the structural reliability of the overall expansion or storage.

[0019] Specifically, a push rod 32 is fixed to the lower end of the guard plate 3, and a push block 21 is fixed on the auxiliary stool 2 to cooperate with the push rod 32. When the auxiliary stool 2 and the guard plate 3 are opened, the push block 21 supports the push rod 32 and stabilizes the guard plate 3 in a vertically open state on the L-shaped column 12. In this embodiment, the push rod 32 and the push block 21 cooperate to enable the guard plate 3 to be locked synchronously with the help of the support leg 5 and the base 11, thereby achieving a linkage effect. It should be noted that the contact surface between the push rod 32 and the push block 21 is arc-shaped, and the center of the arc is concentric with the hinge axis of the auxiliary stool 2 and the body 1.

[0020] Furthermore, an embedded first magnetic plate 321 is provided on one side of the support rod 32, and an embedded second magnetic plate 121 is provided on the side of the L-shaped column 12 to cooperate with the first magnetic plate 321. The two magnetic plates are attracted to each other at one end, and the support rod 32 and the L-shaped column 12 are provided with an interlocking groove for embedding the magnetic block, and then fixed with glue. In this embodiment, by setting the attraction of the two magnetic plates, it can be ensured that the guard plate 3 is in a vertical state when it is opened, thereby facilitating the mutual cooperation between the support block 21 on the auxiliary stool 2 and the support rod 32 on the guard plate 3.

[0021] Specifically, such as Figure 5 As shown, the two guard plates 3 are formed with overlapping connecting ears 33 near one end, and a recessed groove 22 is provided at the upper end of the auxiliary stool 2 for the two connecting ears 33 to enter at the same time. The latch 4 slides in the auxiliary stool 2 and passes through the recessed groove 22 and the connecting ear 33. When the two guard plates 3 are closed, the two connecting ears 33 overlap with each other, and the through holes opened in the connecting ears 33 also overlap. After the latch 4 passes through the two connecting ears 33 under the action of the first spring 42, it is plugged into the auxiliary stool 2 again to ensure a firm connection between the auxiliary stool 2 and the two guard plates 3.

[0022] Furthermore, a hand lever 41 is fixed to one end of the latch 4, and a movable groove 23 for the movement of the latch 4 and the hand lever 41 is provided in the auxiliary stool 2. A first spring 42 is provided between the movable groove 23 and the hand lever 41 to keep the latch 4 in the plugged state. The latch 4 and the hand lever 41 can rotate. When rotating outward, it is convenient to operate the hand lever 41. After rotating inward, the hand lever 41 is stored in the movable groove 23. The first spring 42 keeps the latch 4 plugged in under normal circumstances.

[0023] Specifically, a symmetrical support leg 5 is hinged at the lower end of the auxiliary stool 2, and a storage groove 24 is provided in the auxiliary stool 2 to accommodate the support leg 5. A protrusion 52 is provided on the side of the support leg 5, and a groove that cooperates with the protrusion 52 is provided in the storage groove 24. When the support leg 5 is rotated into the storage groove 24, the protrusion 52 cooperates with the groove in the storage groove 24 to prevent the support leg 5 from rotating freely and easily.

[0024] Furthermore, a socket 111 is provided on the base 11 to be plugged into the bottom of the support leg 5, and a ring groove 51 is provided on the part of the support leg 5 inserted into the socket 111 to cooperate with the lock pin 6. The socket 111 can be set through, and the bottom of the support leg 5 is supported on the ground after being inserted into the socket 111 to prevent the support leg 5 from moving horizontally, and then positioned up and down through the cooperation of the ring groove 51 and the lock pin 6, thereby ensuring the structural stability of the auxiliary stool 2 and the guard plate 3 after opening. The lock pin 6 is two symmetrical ones and is fixed as a whole through a connecting rod 61. A second spring 62 is provided between the connecting rod 61 and the inside of the base 11, which presses against each other. A convex plate 611 protruding from the outside of the base 11 is also formed in the middle of the connecting rod 61. The external convex plate 611 is convenient for the staff to operate with their feet. Under the normal condition of the second spring 62, the lock pin 6 and the ring groove 51 are in an engaged state, and the convex plate 611 is in an outward protruding state.

[0025] Specifically, a handle groove 25 is provided at the bottom of the auxiliary stool 2 near one end of the support leg 5. The auxiliary stool 2 is made of plastic as a whole and is injection molded. The handle groove 25 is also integrally molded by injection molding. The handle groove 25 facilitates the unfolding or storage of the auxiliary stool 2.

[0026] A method for using a self-service vision testing device, based on the above-mentioned testing device, uses the following steps: S1. Pull the latch 4 to the side by the hand lever 41 until it is disengaged from the connecting ear 33, rotate the auxiliary stool 2 downward, and bend the legs 5 outward in the storage slot 24 to expand. The legs 5 remain drooping under the action of gravity. S2. After the guard plate 3 is opened 90°, the lever 32 and the L-shaped column 12 are against each other. At this time, the second magnetic plate 121 and the first magnetic plate 321 attract each other and the guard plate 3 is kept in the open state; S3. The foot pushes the locking pin 6 inward through the convex plate 611, the auxiliary stool 2 continues to rotate downward, the lower end of the support leg 5 enters the socket 111, and the block 21 and the rod 32 are at odds with each other. After the convex plate 611 is released, the locking pin 6 is inserted into the annular groove 51 and locked under the action of the second spring 62.

[0027] It can be understood that synchronous opening and closing can be achieved through the linkage design of the rotating auxiliary stool and the guard plate: the auxiliary stool is convenient for storage and sitting or standing use, and the guard plate can protect precision detectors and smart touch displays; manual operation avoids electric failures, taking into account structural reliability, equipment protection and ease of use.

[0028] A specific application of this embodiment is: Figure 1The figure shows the use state of the device. In this state, the guard plate 3 is opened 90 degrees on the inner side of the L-shaped column 12, the first magnetic plate 321 and the second magnetic plate 121 are attracted to each other, and the block 21 and the rod 32 are in contact and support each other; the auxiliary stool 2 is opened to be parallel to the ground and the bottom of the support leg 5 is inserted into the socket 111. The locking pin 6 cooperates with the annular groove 51 under the action of the second spring 62 to lock the auxiliary stool 2; in this state, the auxiliary stool 2 and the guard plate 3 are both in a locked state to avoid swinging during use. The auxiliary stool 2 is convenient for the user to sit and stand, and the guard plate 3 forms a shield on the side to reduce the reflection of the smart touch display 14, and also plays a protective role on the side of the smart touch display 14; like Figure 2 and Figure 3 The figure shows the storage state of the device. At this time, the guard plate 3 is in contact with the L-shaped column 12 to protect the detector 13 and the smart touch display 14. The auxiliary stool 2 is rotated upward for storage, and the connecting ear 33 is located in the sink 22 and is locked by the pin 4 under the action of the first spring 42.
