Description

Technical Field

[0001] The present invention relates to the technical field of vision detection, and in particular to a movable vision detection device. Background Art

[0002] With the development of the times, more and more electronic products have entered people's lives, and more patients with visual impairment have emerged. When diagnosing them and fitting them with glasses, a preliminary vision test is required. Using an eye chart for vision testing is a common vision testing method. The eye chart is a chart used to measure visual acuity. It is functionally divided into near vision chart and far vision chart. The eye chart is the main tool for testing patient vision in many institutions such as hospitals, physical examination centers, schools, and driving training institutions. The normal testing distance is 5 meters or 2.5 meters (with a plane reflector), the lighting requirement is 500 Lux, and the 1.0 line of the eye chart is parallel to the eye being tested. The vision test chart can first be checked by looking at the distance on the eye chart. The eye chart must be viewed on the corresponding distance line. When checking, cover one eye first and look with the uncovered eye, reading the corresponding numbers from top to bottom until you can no longer see. For vision testing, vision testing should be carried out under medium light brightness, and the lighting in the examination room should be dim. When illuminating the eye chart, the examiner should be careful to avoid glare sources appearing in the patient's field of view.

[0003] The Chinese patent with publication number CN116869466B discloses a movable vision detection device, including a base, a sealing mechanism, a replacement mechanism and an anti-back mechanism. A box is provided on the top of the base, a control box is fixedly connected to the bottom of the box, a controller is provided inside the control compartment, distance height detectors are evenly provided on one side of the box, a control light is provided on the top of the box, and a vision detection chart body is provided inside the box. This device can automatically adjust the height and control the distance, thereby ensuring the accuracy of the detection, and at the same time makes it very convenient for medical staff to use, reducing the workload of medical staff. At the same time, this device is also very simple and convenient to replace the vision detection chart body. After use, the vision detection chart body can also be sealed and stored to ensure the cleanliness of its surface, and it can also be protected to avoid scratches, ensuring its safety and normal use.

[0004] However, most of the movable vision testing equipment such as the above-mentioned ones are fixed or manual, which makes them very inconvenient to use. For some patients who cannot leave their homes or have difficulty leaving home, they need to bring their vision chart to the door for testing. However, the existing equipment is obviously not suitable for portability, and it is difficult to ensure that the vision chart is flat and smoothly unfolded during use. The stability and accuracy are low, and medical staff are required to wipe the equipment frequently, which increases the workload of medical staff. Summary of the Invention

[0028] In the above solution, two hanging rings 51 are respectively provided at both ends of the top of the cover 5 , and a hanging belt 52 for hanging the device is connected between the two hanging rings 51 .

[0029] As an optimized technical solution of the present invention, the strap 52 passes between the two hanging rings 51, and then the entire device can be hung on the wall through the strap 52. In conjunction with the adsorption plate 43, the entire device can be double fixed to ensure the stability of the overall fixation of the device.

[0030] In the above scheme, the winding assembly 8 includes a winding motor 81 and a winding shaft 82. The winding motor 81 is installed on the right side inside the base box 4, and the winding shaft 82 is horizontally arranged inside the base box 4. The winding shaft 82 is connected to the output end of the winding motor 81, and the upper end of the flexible eye chart 1 is wound on the winding shaft 82.

[0031] As an optimized technical solution of the present invention, the winding motor 81 can drive the winding shaft 82 to rotate forward or reverse, thereby realizing the recovery or unfolding of the flexible eye chart 1.

[0032] In the above scheme, the counterweight cylinder 6 is connected to the lower end of the flexible eye chart 1, and cylinder caps 61 are respectively provided at both ends of the counterweight cylinder 6. Two receiving grooves 62 are respectively provided at both ends of the rear side of the counterweight cylinder 6. The support assembly 7 is arranged in the two receiving grooves 62, and the support assembly 7 is connected to the inner side of the cylinder cap 61.

[0033] As an optimized technical solution of the present invention, the gravity of the counterweight cylinder 6 is utilized to ensure the feeling of falling during the recovery or unfolding of the flexible eye chart 1, so that the flexible eye chart 1 can be tightly wound on the winding shaft 82, and the support assembly 7 provided in the retracting and releasing grooves 62 at both ends of the counterweight cylinder 6 can be retracted and released to support the lower end of the flexible eye chart 1 through the support assembly 7, thereby ensuring the flatness of the flexible eye chart 1 after unfolding and preventing the flexible eye chart 1 from shaking during the unfolding process.

[0034] In the above scheme, the support assembly 7 includes a double-headed motor 71, a driving tooth 72, a threaded rod 73, a driven tooth 731, a connecting rod 74, a support arm 75 and a pulley 76. The double-headed motor 71 is installed in the middle of the counterweight cylinder 6, the driving tooth 72 is connected to the output end of the double-headed motor 71, both ends of the threaded rod 73 are rotatably connected to the rear side of the counterweight cylinder 6, the driven tooth 731 is connected to the inner end of the threaded rod 73, the driven tooth 731 is meshed with the driving tooth 72, one end of the support arm 75 is hinged to the inner side of the cylinder cap 61, one end of the connecting rod 74 is hinged to the middle of the support arm 75, the other end of the connecting rod 74 is hinged with a threaded sleeve 741, the threaded sleeve 741 is threadedly connected to the threaded rod 73, and the pulley 76 is arranged at the free end of the support arm 75.

[0035] As an optimized technical solution of the present invention, before the flexible eye chart 1 is unfolded, the double-headed motor 71 can be controlled to drive the active gear 72 to rotate, and then drive the driven gear 731 to rotate, and the driven gear 731 drives the threaded rod 73 to rotate, and then the threaded connection relationship between the threaded rod 73 and the threaded sleeve 741 can be utilized to make the threaded sleeve 741 hinged at the end of the connecting rod 74 move toward the outer end of the threaded rod 73, and push the support arm 75 to release and unfold through the connecting rod 74 until the support arm 75 is completely rotated out of the counterweight cylinder 6, so that the pulley 76 at the free end of the support arm 75 can be abutted against the wall, thereby realizing the support work of the flexible eye chart 1 after unfolding, and ensuring that the flexible eye chart 1 is smoothly unfolded.

[0036] In the above solution, the inner side of the free end of the support arm 75 is slidably connected to the telescopic rod 751 , the inner side of the telescopic rod 751 is provided with a telescopic spring 77 , and the pulley 76 is rotatably connected to the outer side of the telescopic rod 751 .

[0037] As an optimized technical solution of the present invention, the telescopic rod 751 is telescopically provided with a free end of a support arm 75, and a telescopic spring 77 is provided at the inner end of the telescopic rod 751, which can be telescoped during the telescopic process of the telescopic rod 751. The pulley 76 is connected to the free end of the telescopic rod 751, thereby ensuring that the telescopic rod 751 can slide smoothly on the uneven wall surface, ensuring that the main body of the flexible eye chart 1 is perpendicular to the test subject after it is unfolded, thereby improving the accuracy of the test.

[0038] In the above solution, the detection mechanism is connected to the detection pad 3 for measuring human body weight via radio signals, and the detection pad 3 is provided with an infrared sensor for sensing the distance between the human body and the detection mechanism.

[0039] As an optimized technical solution of the present invention, a pressure sensor is provided in the detection pad 3, so that the patient's weight can be measured, and an infrared sensor is provided to detect the patient's position in real time to prevent the patient from moving forward due to not being able to see the flexible eye chart 1 clearly, thereby avoiding deviations in the measurement results.

[0040] In the above scheme, the cleaning component 9 includes a cleaning pressure plate 91, a cleaning cloth 92, a mounting rod 93 and a compression spring 94. The number of the mounting rods 93 and the compression spring 94 are both two. One end of the two mounting rods 93 is connected to the inner side of the two ends of the cleaning pressure plate 91. The two mounting rods 93 are slidably connected in the machine cover 5 through a ring. The two compression springs 94 are respectively installed at the other ends of the two mounting rods 93. The compression springs 94 abut against the inner side of the machine cover 5. The cleaning cloth 92 is wrapped around the outside of the cleaning pressure plate 91, and the cleaning cloth 92 abuts against the outer surface of the flexible eye chart 1.

[0041] As an optimized technical solution of the present invention, during the recovery or expansion process of the flexible eye chart 1, the elastic properties of the compression spring 94 can be utilized to keep the cleaning cloth 92 pressed against the flexible eye chart 1 through the cleaning pressure plate 91, which can not only scrape and clean the dust on the main surface of the flexible eye chart 1, but also smooth the surface of the flexible eye chart 1, ensuring that the flexible eye chart 1 is prevented from getting stuck at the inlet and outlet during the recovery and expansion process.

[0042] Specific implementation cases: When using the vision detection device, the device is hung on the wall at a suitable height through the strap 52, and the bottom box 4 is adsorbed on the wall using the adsorption plate 43 on the rear side of the bottom box 4 to complete the fixed installation of the entire device.

[0043] Secondly, the double-headed motor 71 is controlled by the remote control 2 to drive the active gear 72 to rotate, and then the threaded rod 73 is driven to rotate through the driven gear 731. The threaded sleeve 741 and the threaded rod 73 are matched with each other to make the threaded sleeve 741 move toward the outer end of the threaded rod 73, and then the support arm 75 is stretched open by the connecting rod 74 until the support arm 75 is perpendicular to the counterweight cylinder 6.

[0044] Then, the controller 2 can be used to control the winding motor 81 to rotate, thereby driving the winding shaft 82 to rotate, so that the flexible eye chart 1 is released, and then the flexible eye chart 1 can be stably unfolded under the action of the gravity of the counterweight cylinder 6, and the flexible eye chart 1 can be smoothly unfolded on the wall surface (or uneven wall surface) in conjunction with the telescopic spring 77, telescopic rod 751 and pulley 76 in the support assembly 7, thereby ensuring that the flexible eye chart 1 is perpendicular to the person being tested after unfolding, thereby improving the accuracy of vision testing.

[0045] At the same time, the detection pad 3 is placed at a suitable position in front of the flexible eye chart 1, the person being tested stands on the detection pad 3, the patient's weight is measured, and the winding component 8 is controlled to recycle or unfold the flexible eye chart 1, so that the person being tested's line of sight is parallel to 1.0 on the flexible eye chart 1, so as to control the main body of the flexible eye chart 1 to be horizontally aligned with the line of sight of the people being tested of different heights, so as to complete the patient's vision test.

[0046] Finally, after the patient's vision test is completed, the support component 7 can be controlled to retract into the retracting groove 62 at both ends of the counterweight cylinder 6, and at the same time, the winding motor 81 can be controlled to drive the winding shaft 82 to wind the flexible eye chart 1 back into the bottom box 4, and the dust on the flexible eye chart 1 can be cleaned in time through the cleaning component 9, and the flexible eye chart 1 can be flattened. When the flexible eye chart 1 is retracted into the bottom box 4, the entire device looks like a long tube, which is convenient for medical staff to carry when going out. It has strong mobility and simple structure, which greatly improves the convenience of medical staff during use.

[0047] The increasing market demand for portable vision testing devices is driving the continued miniaturization and lightweighting of related products. Future portable vision testing devices will be even more portable, allowing users to conveniently perform vision tests at home, in the office, or in public places. This portability not only increases the convenience of testing but also helps promote the popularization of vision testing, enabling more people to regularly monitor their vision status.

[0048] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
