Description

Technical Field

[0001] The present invention relates to the technical field of ophthalmic devices, and in particular to an ophthalmic biometric device. Background Art

[0002] Ophthalmology, whose full name is "ophthalmic disease specialty", is a discipline that studies diseases occurring in the visual system, including the eyeball and its associated tissues. Ophthalmic diseases have a relatively high incidence rate, seriously affecting people's quality of life. Most use optical biometers to measure the eyes. The biometer is a commonly used measuring device in ophthalmology and can detect ophthalmic diseases, pupil parameters, etc. Existing biometers include a fixed base, a detection instrument body and a supporting part provided on the fixed base. During operation, the chin of the person being examined is placed on the supporting plate inside the supporting part, and the person visually observes the detection instrument body for detection. However, since the existing supporting plate has a simple structure, which is just a flat plate without a fixing structure, during detection, due to the movement of the person's head, the eyes cannot be directly aligned with the detection instrument body, bringing difficulties to the detection process, especially when detecting children. To solve the above problems, an ophthalmic biometric device is proposed in the present invention. Summary of the Invention

Detailed implementation manners

[0016] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings understood by those of ordinary skill in the art in the field to which the present invention belongs. The words such as "including" used herein mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects.

[0017] In view of the problems existing in the prior art, the embodiments of the present invention provide an ophthalmic biometry device. As Figure 1 and Figure 2 shown, the ophthalmic biometry device includes a fixed seat 1, and a supporting part 2 and an instrument body 3 provided on the fixed seat 1. The instrument body 3 is used for detecting the eyes, and the supporting part 2 is used for supporting the head.

[0018] Among them, in Figure 2In the example, the supporting part 2 includes a supporting bracket 21. A placing hole 22 for placing the head is formed in the supporting bracket 21. A main supporting plate 23 for supporting the chin is arranged below the placing hole 22. A first sensor 26 is arranged on the main supporting plate 23, and the upper end of the first sensor 26 is exposed outside the main supporting plate 23, so as to ensure that the first sensor 26 can directly contact the chin, thereby enabling more accurate sensing. And a first clamping assembly 24 and a second clamping assembly 25 are respectively arranged at opposite ends (which can be understood as the left and right ends) of the main supporting plate 23. Third sensors 28 and second sensors 27 are respectively arranged on the first clamping assembly 24 and the second clamping assembly 25, and the third sensors 28 and the second sensors 27 are respectively exposed outside the first clamping assembly 24 and the second clamping assembly 25 to ensure that the third sensors 28 and the second sensors 27 can accurately provide contact information with the cheeks. During operation, when the first sensor 26 senses that the chin is placed on the main supporting plate 23, the first clamping assembly 24 and the second clamping assembly 25 will perform a rotational closing movement towards the vertical center line of the main supporting plate 23 and clamp and fix the two sides of the face. It can be understood that the first clamping assembly 24 contacts the left cheek and the second clamping assembly 25 contacts the right cheek. When the second sensor 27 and / or the third sensor 28 contacts the cheek, the first clamping assembly 24 and the second clamping assembly 25 stop performing the rotational closing movement.

[0019] Preferably, in one example, the structures of the first clamping assembly 24 and the second clamping assembly 25 are the same, and the amplitudes of the rotational movements are the same. During operation, the chin is placed on the vertical center line of the main supporting plate 23, so that the first clamping assembly 24 and the second clamping assembly 25 can simultaneously contact the left and right sides of the cheek. Therefore, in implementation, the third sensor 28 can be arranged only on the first clamping assembly 24, the second sensor 27 can be arranged only on the second clamping assembly 25, and at the same time, the third sensor 28 and the second sensor 27 can also be respectively arranged on the first clamping assembly 24 and the second clamping assembly 25 at the same time. The settings of these three examples can all control the rotational end points of the first clamping assembly 24 and the second clamping assembly 25, and can ensure that when the first clamping assembly 24 and the second clamping assembly 25 are at the rotational end points, they can clamp and fix the cheek. It should be noted that the structural design in the present invention is reasonable, and the rotational amplitudes of the first clamping assembly 24 and the second clamping assembly 25 are both between 0 - 90°, so that the device can be applicable to testers with different face shapes, making the applicable range of the device wider.

[0020] In one implementation manner, as Figure 3As shown, the supporting portion 2 further includes two connecting components 29 respectively for connecting the main supporting plate 23 and the first clamping assembly 24, and connecting the main supporting plate 23 and the second clamping assembly 25. Specifically, one of the connecting components 29 is used for connecting the left end of the main supporting plate 23 and the right end of the first clamping assembly 24, and the other connecting component 29 is used for connecting the right end of the main supporting plate 23 and the left end of the second clamping assembly 25. The connecting component 29 includes a connecting gap 291 provided between the main supporting plate 23 and the first clamping assembly 24, and a connecting hinge 292 provided in the connecting gap 291. Two ends of the connecting hinge 292 are respectively fixedly connected to side walls of the main supporting plate 23 and the first clamping assembly 24. The setting of the connecting hinge 292 enables the first clamping assembly 24 or the second clamping assembly 25 to rotate around the center of the connecting hinge 292. The connecting component 29 further includes a third elastic cloth 293. The third elastic cloth 293 is arranged near the upper part of the connecting gap 291. Two ends (which can be understood as the left and right ends) of the third elastic cloth 293 are respectively fixedly connected to the main supporting plate 23 and the first clamping assembly 24. The third elastic cloth 293 can block the connecting gap 291 to prevent the face from being pinched when the first clamping assembly 24 or the second clamping assembly 25 rotates. And the upper end surface of the third elastic cloth 293 and the upper end surfaces of the main supporting plate 23 and the first clamping assembly 24 are arranged on the same smooth arc line, and such setting can play a better protective role for the face.

[0021] In order to be able to intelligently control the rotation of the first clamping assembly 24 and the second clamping assembly 25, in one implementation, as Figure 4As shown, the ophthalmic biometrics device further includes a support drive mechanism 4, which includes a support box 41 fixedly arranged on the bottom wall of the placement hole 22, a second through hole 43 is opened on the top plate of the support box 41, and two fourth elastic cloths 44 are fixedly arranged on the outer wall of the support box 41, and the free ends (which can be understood as the upper ends) of the two fourth elastic cloths 44 are respectively fixedly connected to the first clamping assembly 24 and the second clamping assembly 25, and the fourth elastic cloth 44 is arranged to block the gap between the first clamping assembly 24 and the second clamping assembly 25 and the support box 41, so as to achieve a safer protection effect. The support drive mechanism 4 also includes a support column 42 fixedly arranged on the lower end surface of the main support plate 23, and the lower end of the support column 42 is fixedly connected to the inner bottom wall of the support box 41. In one example, the support column 42 is movably arranged in the second through hole 43 and does not contact the wall of the second through hole 43. In another example, the support column 42 is fixedly arranged in the second through hole 43. A driving cylinder 45 is fixedly connected to the inner bottom wall of the support box 41, and a cylinder arm 46 is connected to the driving end of the driving cylinder 45. Two push-pull rods 47 are symmetrically hinged on the upper end of the cylinder arm 46. The free ends of the two push-pull rods 47 move through the second through hole 43 and are respectively hinged on the lower end surfaces of the first clamping assembly 24 and the second clamping assembly 25.

[0022] During operation, when the first sensor 26 senses that the chin is placed on the main support plate 23, the driving cylinder 45 is activated. The operation of the driving cylinder 45 drives the cylinder arm 46 to move upward. The upward movement of the cylinder arm 46 pushes the first clamping assembly 24 to rotate clockwise around the center of the hinge 292 through a push-pull rod 47, and pushes the second clamping assembly 25 to rotate counterclockwise around the center of the hinge 292 through another push-pull rod 47. In this way, the face is clamped and fixed from the left and right sides of the cheek through the rotation of the first clamping assembly 24 and the second clamping assembly 25. When the second sensor 27 and the third sensor 28 come into contact, the first clamping assembly 2 4 and the second clamping assembly 25 contact the cheeks on both sides of the face to complete the clamping and fixing process. At the same time, the driving cylinder 45 is controlled to be closed, the first clamping assembly 24 and the second clamping assembly 25 stop rotating, and the current positions of the first clamping assembly 24 and the second clamping assembly 25 are locked through the structure of the driving cylinder 45 itself; after the detection is completed, when the chin is separated from the main supporting plate 23 upward, that is, the chin is separated from the first sensor 26, at this time, the first sensor 26 controls the driving cylinder 45 to provide a driving force in the reverse direction, so that the cylinder arm 46 moves, and pulls the first clamping assembly 24 and the second clamping assembly 25 through the push-pull rod 47 to perform a reset movement and separate from the face.

[0023] It is worth noting that when the device is used, the movement of the jaw is in the vertical direction.

[0024] In one embodiment, as Figure 5 shown, the first clamping assembly 24 includes a support soft plate assembly 241 and a support hard plate 242 that are fixedly connected. The support hard plate 242 is disposed below the support soft plate assembly 241. During operation, the support soft plate assembly 241 directly contacts the face. This can avoid damage to the face caused by excessive squeezing. At the same time, it can also reduce the temperature difference between the face and the support soft plate assembly 241, reducing the uncomfortable feeling of the subject caused by the temperature difference.

[0025] Especially in winter, the temperature is already very low. When the face contacts the support soft plate assembly 241, due to the large temperature difference, it will cause extreme discomfort when using the device. To solve the above problems, in Figure 5 the example, a plurality of ventilation holes (not shown) are provided on the support soft plate assembly 241. An equalization cavity 243 is formed inside the support hard plate 242. A plurality of first through holes 244 are formed in the support hard plate 242. The first through holes 244 are used to communicate the ventilation holes and the equalization cavity 243. A heating grid 245 is fixedly disposed in the equalization cavity 243. It should be understood that the heating grid 245 is a plate-shaped structure, and the four surfaces of the heating grid 245 are fixedly connected to the four walls of the equalization cavity 243. A blower 246 is disposed on the support hard plate 242. The air outlet of the blower 246 communicates with the equalization cavity 243, and the blower 246 is disposed below the heating grid 245. When the device operates in winter, the first sensor 26 will synchronously control the operation of the heating grid 245 and the blower 246. The cold air generated by the blower 246 becomes hot air after passing through the heating grid 245. The hot air will heat the support soft plate assembly 241 through the first through holes 244 and the ventilation holes, thereby reducing the temperature difference between the support soft plate assembly 241 and the face, making the subject more comfortable during detection.

[0026] It should be noted that the heating grid 245 and the blower 246 are respectively further provided with manual control switches (not shown). Such a setting can turn on and off the series circuit of the heating grid 245 and the blower 246 manually, making the device more widely applicable. For example, in winter, manually turn on the series circuit of the heating grid 245 and the blower 246, and the heating grid 245 and the blower 246 can be started to adjust the temperature difference between the face and the device; in summer, manually turn off the series circuit of the heating grid 245 and the blower 246, and the heating grid 245 and the blower 246 will not start, achieving the effect of saving resources.

[0027] In winter, since the air is very dry, in order to enable the device to maintain the face and add a moisturizing effect to the face during the detection process, this process can also avoid the problem of facial dehydration caused by the contact of hot and dry air with the face during the above temperature adjustment process. In one embodiment, as Figure 6 and Figure 7 shown, the ophthalmic biometric device further includes a humidifying mechanism 5. The humidifying mechanism 5 includes a storage tank 51 fixedly arranged in the support box 41. A liquid filling port 55 is arranged on the side wall of the storage tank 51. The liquid filling port 55 is used to add liquid into the storage tank 51. A liquid pump 52 is fixedly arranged on the top plate of the storage tank 51. The water inlet pipe of the liquid pump 52 is arranged in the storage tank 51. An elastic tube 53 is connected to the water outlet pipe of the liquid pump 52. In this embodiment, the elasticity of the elastic tube 53 is utilized. On the one hand, it avoids the influence on the rotation of the first clamping assembly 24 or the second clamping assembly 25 by the humidifying mechanism 5. At the same time, it can also prevent the elastic tube 53 from being damaged due to excessive stretching. The upper end of the elastic tube 53 is connected to a spray head 54. The spray head 54 is fixedly inserted into the support hard plate 242, and the liquid outlet of the spray head 54 is arranged in the balance cavity 243. The liquid outlet of the spray head 54 faces the blower 246.

[0028] During operation, when the chin touches the first sensor 26, the first sensor 26 will start the liquid pump 52. The operation of the liquid pump 52 will pump out the liquid in the storage tank 51 and spray it onto the directly above the blower 246 through the spray head 54. In this way, the operation of the blower 246 will integrate the liquid mist into the cold air, and after being heated by the heating grid 245, it will be transmitted to the support soft plate assembly 241 and the face. On the one hand, it reduces the temperature difference between the support soft plate assembly 241 and the face, and on the other hand, it moisturizes the face.

[0029] It should be noted that the heating grid 245, the blower 246, and the liquid pump 52 can work independently and not simultaneously, or they can work simultaneously. It can be understood that when the detection is completed, the liquid pump 52 stops working first, and then the heating grid 245 and the blower 246 stop working. The purpose of doing this is that the continuous operation of the heating grid 245 and the blower 246 will dry the support soft plate assembly 241, avoiding the growth of bacteria when the support soft plate assembly 241 is in a wet state for a long time, and at the same time, it can also protect the device.

[0030] In order to avoid damage to the face caused by excessive hot air after heating, in one embodiment, as Figure 8As shown, the ophthalmic biometric device further includes a constant temperature mechanism 6, which is used to adjust the temperature of the hot air to avoid damage to the face caused by excessive hot air temperature. Preferably, through the setting of the constant temperature mechanism 6, the temperature of the hot air is adjusted to be the same as the temperature of the face. The constant temperature mechanism 6 includes a partition board 61 fixedly arranged in the balance cavity 243. The partition board 61 divides the balance cavity 243 into two non-communicating cavities, upper and lower, and the partition board 61 is arranged between the first through hole 244 and the heating mesh 245. A number of special-shaped tubes 63 are arranged on the partition board 61, and the special-shaped tubes 63 are used for the communication between the upper and lower cavities. The special-shaped tubes 63 are fixedly inserted into the temperature adjustment board 64, and the temperature adjustment board 64 is fixedly arranged on the temperature regulator 65, and the temperature regulator 65 is fixedly arranged in the balance cavity 243.

[0031] In this embodiment, the temperature regulator 65 is used to control the temperature of the temperature adjustment board 64, and the temperature adjustment board 64 is used to control the temperature of the special-shaped tubes 63 (it should be understood that the temperature of the tube wall and the inner cavity of the special-shaped tube 63 is the same, and the special-shaped tube 63 is made of heat-conducting material); during operation, the hot air passing through the heating mesh 245 will enter the first through hole 244 through the special-shaped tubes 63, so that the temperature of the hot air entering the first through hole 244 can be ensured to be the same as the temperature of the special-shaped tubes 63. By controlling the temperature of the special-shaped tubes 63, the temperature of the hot air entering the first through hole 244 can be controlled. Therefore, in actual use, the temperature of the hot air contacting the face can be adjusted as needed.

[0032] In one embodiment, as Figure 8 shown, a fourth sensor 62 is arranged on the lower end surface of the partition board 61 and / or the inner side wall of the special-shaped tube 63. The fourth sensor 62 is used to monitor the temperature of the hot air passing through the heating mesh 245 in real time; in one example, the fourth sensor 62 is arranged on the lower end surface of the partition board 61, in another example, the fourth sensor 62 is arranged on the inner side wall of the special-shaped tube 63, and in the third example, the fourth sensor 62 is arranged on both the lower end surface of the partition board 61 and the inner side wall of the special-shaped tube 63. The setting of the fourth sensor 62 is used to monitor the temperature of the hot air entering the special-shaped tube 63 in real time, and at the same time, it is also used to monitor the temperature of the special-shaped tube 63 in real time, so that the temperature of the hot air and the temperature of the special-shaped tube 63 are more controllable, and further the accuracy of the device during use is higher.

[0033] In one embodiment, as Figure 8As shown, the special-shaped pipe 63 includes a trumpet pipe 631 fixedly plugged on the baffle plate 61, and the structural setting of the trumpet pipe 631 can play a better role in guiding the flow, so that the hot air passing through the heating network 245 can enter the special-shaped pipe 63 more and faster for temperature adjustment. And a first arc-shaped pipe 632 connected to the upper end of the trumpet pipe 631, the free end (which can be understood as the right end) of the first arc-shaped pipe 632 is connected to the second arc-shaped pipe 633, and the free end (which can be understood as the right end) of the second arc-shaped pipe 633 is connected to the straight pipe 634, the trumpet pipe 631, the first arc-shaped pipe 632, the second arc-shaped pipe 633 and the straight pipe 634 are all made of heat-conducting materials, and the trumpet pipe 631, the first arc-shaped pipe 632, the second arc-shaped pipe 633 and the straight pipe 634 are all fixedly plugged on the temperature adjustment plate 64.

[0034] In this embodiment, the trumpet tube 631, the first arc tube 632, the second arc tube 633 and the straight tube 634 form an inverted "S" structure as a whole, which can increase the movement path of the hot air in the special-shaped tube 63 and delay the movement time of the hot air in the special-shaped tube 63, that is, the temperature adjustment time. In this way, it can be ensured that the hot air coming out of the upper port of the straight tube 634 is consistent with the temperature on the special-shaped tube 63, ensuring the effectiveness of temperature adjustment through the special-shaped tube 63.

[0035] It is worth noting that the trumpet tube 631, the first arc tube 632, the second arc tube 633 and the straight tube 634 can be prepared by integral molding or by segmented welding, which will not be described in detail here.

[0036] After the detection is completed, the face needs to move upward to separate from the main support plate 23. In order to avoid damage to the face caused by friction between the face and the first clamping assembly 24 and the second clamping assembly 25 during the process, in one embodiment, Figure 9 and Figure 10 As shown, the supporting soft board assembly 241 includes a first soft board 2411 and a second soft board 2412. The first soft board 2411 is provided with an anti-friction groove 2413. The second soft board 2412 is movably arranged in the anti-friction groove 2413. When working, the cheek and the second soft board 2412 and the third sensor 28 are arranged on the second soft board 2412. When working, the cheek and the second soft board 2412 and the third sensor 28 conflict with each other. When the face moves upward, the cheek will move upward in the anti-friction groove 2413 with the second soft board 2412, so that the cheek and the second soft board 2412 can be prevented from sliding against each other, thereby protecting the face.

[0037] In one example, Figure 10As shown, a first elastic cloth 2414 is fixedly arranged at one end (which can be understood as the right end) of the second flexible board 2412. The free end (which can be understood as the right end) of the first elastic cloth 2414 is fixedly connected to the side wall of the anti-friction groove 2413. The other end (which can be understood as the left end) of the second flexible board 2412 is fixedly connected to a second elastic cloth 2415. The free end (which can be understood as the left end) of the second elastic cloth 2415 is fixedly connected to the side wall of the anti-friction groove 2413. The upper end surfaces of the first flexible board 2411, the second flexible board 2412, the first elastic cloth 2414 and the second elastic cloth 2415 are all arranged on the same smooth curve. The first elastic cloth 2414 and the second elastic cloth 2415 can, on the one hand, realize the connection between the first flexible board 2411 and the second flexible board 2412, and on the other hand, can realize the protection of the face, which is the same as the functions of the third elastic cloth 293 and the fourth elastic cloth 44, and will not be elaborated here.

[0038] In one embodiment, as Figure 10 shown, the support flexible board assembly 241 further includes a guiding assembly 2416. One end (which can be understood as the right end) of the guiding assembly 2416 is fixedly connected to the second flexible board 2412. The other end (which can be understood as the left end) of the guiding assembly 2416 is fixedly connected to the side wall of the anti-friction groove 2413. The guiding assembly 2416 includes a guiding rod 24161, a guiding cylinder 24162 and a guiding spring 24163. The guiding rod 24161 is movably inserted into the guiding cylinder 24162. The guiding spring 24163 is wound around the guiding rod 24161. One end (which can be understood as the right end) of the guiding spring 24163 is fixedly connected to the side wall of the guiding rod 24161. The other end (which can be understood as the left end) of the guiding spring 24163 is fixedly connected to the outer side wall of the guiding cylinder 24162.

[0039] The arrangement of the guiding assembly 2416 in this embodiment can, on the one hand, play a guiding and supporting role for the movement of the second flexible board 2412, so that the second flexible board 2412 can only move along the cavity of the anti-friction groove 2413. At the same time, it can also provide a restoring force for the restoring process of the second flexible board 2412.

[0040] It should be noted that since the structures of the first clamping assembly 24 and the second clamping assembly 25 are the same, only the detailed structure of the first clamping assembly 24 is shown in this application, and the detailed structure of the second clamping assembly 25 will not be elaborated.

[0041] Although the embodiments of the present invention have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are all within the scope and spirit of the present invention. Moreover, the present invention as described herein can have other embodiments and can be implemented or realized in various ways.
