[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This invention enables subjects to complete vision testing independently through automatic calling, without the need for staff assistance, greatly reducing manpower requirements. It also offers better testing accuracy. Through a screw-driven structure that works in conjunction with an electronic display board, the electronic display board shows vision test symbols of different sizes. With the adjustment of the distance using the screw-driven structure, the vision status of the subject is accurately determined. The electronic display board randomly displays only one vision test symbol at a time. The subject inputs the direction of the symbol through an interactive button, thus avoiding the shortcomings of traditional paper vision test charts that can be cheated by memorization.

[0014] The conductive structure can detect whether the head of the person being sampled is in contact with the head positioning plate, thereby ensuring the uniformity of the head position of the person being sampled, further reducing the sampling error, and preventing the person being sampled from cheating by tilting their head forward. In addition, the conductive structure has a certain range of follow-up contact function to prevent the small-amplitude head shaking of the person being sampled from affecting the sampling process.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 5 This invention provides a technical solution: an intelligent vision acquisition system based on automatic calling, including an acquisition anti-slip seat 1 and a vertical backrest 2. The vertical backrest 2 is fixedly installed on the rear surface of the acquisition anti-slip seat 1 and is perpendicular to the upper surface of the acquisition anti-slip seat 1. A response control box 3 is fixedly installed above the acquisition anti-slip seat 1. The response control box 3 is an interactive control component between the subject and the intelligent vision acquisition system. A lifting adjustment cylinder 4 is fixedly installed on the rear surface of the vertical backrest 2. A screw drive structure is provided above the lifting adjustment cylinder 4. An electronic display panel 5 is fixedly installed outside the screw drive structure. The electronic display panel 5 is a common liquid crystal display panel that can display vision test symbols of different sizes, which is a common existing technology. A head positioning backrest 6 is movably installed on the front surface of the vertical backrest 2 near the upper position. A conductive structure with follow-up contact function is provided between the head positioning backrest 6 and the vertical backrest 2.

[0023] The lifting and adjusting cylinder 4 has a back plate fixing eave 401 fixedly installed on both sides of its surface. A receiving cavity 402 is opened on the upper surface of the lifting and adjusting cylinder 4. A telescopic support column 403 is movably inserted into the receiving cavity 402. A set screw disc 404 is spirally installed on the outer surface of the lifting and adjusting cylinder 4. The threaded column of the set screw disc 404 spirally passes through the side wall of the lifting and adjusting cylinder 4 and abuts against the outer surface of the telescopic support column 403. The screw drive structure includes a support rail guide rod 405, a drive screw 406, a power drive box 407, a connecting end plate 408, and a slider support plate 409. The support rail guide rod 405 is fixedly installed on the outer surface of the telescopic support column 403, and the drive screw 406 is rotatably installed... A power drive box 407 is fixedly installed on the outer surface of the telescopic support column 403. The power drive box 407 is controlled by a stepper or servo motor and can be speed-changed through a gear set, which can be easily achieved with existing technology. The power drive box 407 is connected to the drive screw 406. A connecting end plate 408 is fixedly installed on the other end surface of the support rail rod 405 and the drive screw 406. A slider support plate 409 is provided on the outside of the support rail rod 405 and the drive screw 406. The drive screw 406 and the slider support plate 409 are screwed together. The electronic display board 5 is fixedly installed on the outer surface of the slider support plate 409.

[0024] The conductive structure includes a positioning guide post 601, a positioning mating hole 602, a support spring 603, a pressure-bearing top post 604, a top post through hole 605, a contact detection shell 606, a contact top plate 607, a mating contact plate 608, and a follow-up support spring 609. The positioning guide post 601 is fixedly installed on the rear surface of the head positioning backrest 6. The positioning mating hole 602 is located inside the vertical backrest 2, through which the positioning guide post 601 passes. The support spring 603 is sleeved and fixed on the outside of the positioning guide post 601, located between the vertical backrest 2 and the head positioning backrest 6. The pressure-bearing top post 604 is fixedly installed on the rear surface of the head positioning backrest 6. The top post through hole 605 is located inside the vertical backrest 2, through which the pressure-bearing top post 604 passes. The contact detection shell 606 is fixedly installed on the head positioning backrest. At the rear surface of position 6, one end of the pressure-bearing top post 604 is inserted into the interior of the contact detection housing 606. The surface of one end of the pressure-bearing top post 604 is located inside the contact detection housing 606 and a contact top plate 607 is fixedly installed. The mating contact plate 608 is located inside the contact detection housing 606 and is coaxially arranged with the contact top plate 607. The follower support spring 609 is fixedly arranged between the mating contact plate 608 and the inner wall surface of the contact detection housing 606. The contact top plate 607 and the mating contact plate 608 do not contact each other in their natural state. When the head positioning plate 6 is subjected to pressure, the contact top plate 607 and the mating contact plate 608 can maintain contact within a certain range. When the contact top plate 607 and the mating contact plate 608 are in contact, a feedback signal can be sent to the control system. Therefore, both the contact top plate 607 and the mating contact plate 608 are made of conductive material.

[0025] A support leg 101 is fixedly installed on the lower surface of the anti-slip seat 1. An armrest frame 102 is fixedly installed on the upper surface of the anti-slip seat 1 near both sides. The response control box 3 is fixed on the armrest frame 102. An interactive button 301 is provided on the surface of the response control box 3. An movable groove 201 is provided on the surface of the vertical backrest 2.

[0026] This invention discloses an intelligent vision acquisition system based on automatic calling. During use, a voice call prompts the subject to sit on the anti-slip seat 1, with their head pressed against the head positioning backrest 6. This causes the contact top plate 607 to contact the mating contact plate 608. Once the contact top plate 607 and mating contact plate 608 reach their contact points, the vision test pauses, and the subject is reminded to return their head to its normal position. This prevents the subject from tilting their head forward to cheat. Supported by the follow-up support spring 609, minor head movements do not affect the contact between the contact top plate 607 and mating contact plate 608. Vision test symbols are displayed on the electronic display board 5. The orientation of the symbols is input via the interactive button 301, and the screw-driven structure changes the display position of the electronic display board 5, thus accurately measuring the subject's vision.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
