Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a pair of smart glasses for elderly people that are easy to replace lenses when going out. Background Art

[0002] As the aging of the population in my country gradually intensifies, the health and protection of the elderly have also begun to attract the attention of the whole society. Today, the aging of the Chinese society is gradually intensifying, reflecting the characteristics of aging and empty nest. According to the data reported by the China Association of Aged Care, there are more than 60,000 kinds of elderly products in the world, but only more than 2,000 kinds in China. The demand for intelligent protection of the elderly is obvious, and the use of intelligent protection products for the elderly can greatly reduce the pressure of the young population on the elderly care, which has positive significance for social development.

[0003] Smart wearable devices for the elderly can be divided into wearable devices for monitoring human indicators and recording movement trajectories, such as wearable ECG clothes, smart bracelets and smart socks; wearable devices for information interaction and convenient entertainment, such as smart digital glasses; wearable devices for safety protection, such as anti-fall shoes that can monitor the real-time status of the elderly, vests that pop out airbags in time to protect important parts when the elderly fall, and exoskeleton robots that assist the elderly in walking, etc.

[0004] At present, there are few smart glasses products used in elderly care and health care equipment. As a wearable device, glasses can give people real-time feedback. As a member of the elderly care wearable device product, smart glasses have unique advantages. First of all, the elderly often need to wear reading glasses to see things clearly, so wearing smart glasses can first solve the problem of presbyopia. Secondly, unlike smart bracelets or smart watches, sometimes the elderly may not be able to notice the information sent by smart bracelets or smart watches in time, while smart glasses can give the elderly the most intuitive feedback through lenses or ear conduction headphones. Smart glasses are small in size and the elderly are highly dependent on them. There is no situation where the elderly forget to wear or lose them, and they are highly safe.

[0005] Compared with young people, the elderly have more time to go out in their daily lives. Traveling and relaxing in daily life are more beneficial to the physical and mental health of the elderly. When the elderly travel or walk outside, they usually need to carry reading glasses, sun hats and other tools to face different external environments.

[0006] At the same time, when going out, if the lens is broken or damaged, it cannot be effectively treated. If you continue to carry it, it may damage the elderly's glasses. If you do not carry it, it will become difficult to see the objects clearly.

[0088] like Fig.23 As shown in the figure, after the stator switch 321 is squeezed, the stator telescopic member 342 is extended, driving the stator accommodating device 4 to extend from the stator storage device 3, and then the stator telescopic member 342 will contract and return to the initial position;

[0089] like Fig.24 As shown, the lens frame 5 is a rectangular plate-shaped structure, the middle part of the lens frame 5 is set as a lens 51, and circular hole-shaped fixing plate fixing grooves 52 are set on both sides of the lens frame 5. The size of the fixing plate fixing grooves 52 is the same as the size of the fixing plate fixing column 421 on the fixing plate 42. A rectangular groove with the same diameter as the fixing plate fixing groove 52 is set on the top of the lens frame 5, providing space for the fixing plate fixing column 421 when the fixing plate 42 moves up and down; a plurality of fixing plate sliding grooves 53 are set on the inner walls of the upper and lower sides of the lens frame 5, and the size of the fixing plate sliding grooves 53 is the same as the fixing plate sliding protrusions 422 on the fixing plate 42. When the fixing plate accommodating device 4 is aligned with the lens frame 5, the fixing plate 42 can be combined with the lens frame 5 under the action of external force, and the fixing plate sliding protrusions 422 of the fixing plate 42 enter the fixing plate sliding grooves 53 of the lens frame 5, and the fixing plate fixing column 421 of the fixing plate 42 enters the fixing plate fixing groove 52 of the lens frame 5; the lens fixing device 54 is set at a side corner position of the lens frame 5;

[0090] like Fig.25 , Fig.26 As shown, the lens fixing device 54 is composed of an "L"-shaped lens fixing block 541 connected to the inner wall of the lens frame 5 through a spring 543. A section of the "L"-shaped lens fixing block 541 extending out of the lens frame 5 is a toggle block 542. The user can move the toggle block 542 to compress the spring 543, so that the lens fixing block 541 shrinks and enters the inside of the lens frame 5. After the user releases the toggle block 542, the spring 543 automatically recovers under the action of its own elastic force, so that the lens fixing block 541 extends out from the inside of the lens frame 5. The size of the lens fixing block 541 is the same as the size of the lens fixing groove 17 on the frame 1. When the lens frame 5 is inside the frame 1, the lens fixing block 541 is inside the lens fixing groove 17, so that the lens frame 5 is fixed inside the frame 1.

[0091] like Fig. 27As shown, the pushing device 6 is composed of a rectangular block-shaped pushing rod driving device 61 connected to a connecting plate 63 via a pushing rod 62. The pushing rod 62 is a retractable rod-shaped structure, and the pushing rod driving device 61 can extend the pushing rod 62 by a certain distance;

[0092] The sliding switches 18 on both sides of the frame 1 are switches for controlling the push device 6. When the sliding switches 18 slide to the upper end, the push device 6 remains in its original state ( Fig. 27 When the slide switch 18 slides to the lower end, the push rod 62 of the push device 6 is extended for a certain distance;

[0093] like Fig.28 As shown, this figure is a schematic diagram of the state when the pushing device 6 is inside the pushing device receiving groove 115 in the frame 11;

[0094] like Fig.29 As shown, the temples 7 are arranged on both sides of the frame 1, and one side of the temple 7 is provided with a temple connecting groove 71, which is connected to the temple connecting shaft 12 of the frame 1, so that the temples 7 are connected to the two sides of the frame 1; the other side of the temple 7 is an ear support part made of soft rubber material, which is convenient for the user to wear; the temple 7 is provided with a battery 72, which is convenient for providing power for other internal components of the glasses; the smart module 1 73 arranged on the temple 7 is a paging and listening module, which is convenient for the user (elderly) to contact with family members through the glasses; the smart module 2 74 arranged on the temple 7 is a positioning module, and the positioning function can interact with the Beidou navigation, so that family members and children can always grasp the location information of the elderly, and can rush to the elderly in the first time when an accident occurs, so as to prevent the occurrence of danger;

[0095] like Fig.30 , Fig.31 As shown, the figure is a schematic diagram of the position state when the fixed sheet accommodating device 4 and the lens frame 5 are inside the frame 1; at this time, the fixed sheet accommodating device 4 enters the frame 11 along the fixed sheet slot 114 of the frame 11, and as the fixed sheet accommodating device 4 moves downward, the connecting plate 63 of the pushing device 6 enters the "T"-shaped pushing device sliding slot 411 of the fixed sheet accommodating device 4 until the fixed sheet accommodating device 4 moves to the bottom, and at this time, the fixed sheet fixing column 421 of the fixed sheet accommodating device 4 and the fixed sheet fixing slot 52 on the lens frame 5 are on the same axis. At this time, the sliding switch 18 located on both sides of the frame 1 is slid downward to enable the pushing device 6 to work, so that the pushing rod 62 of the pushing device 6 is extended for a distance, thereby pushing the fixed sheet 42 into the lens frame 5;

[0096] like Fig.32As shown, the figure is a schematic diagram of the state when the fixing plate 42 enters the lens frame 5. At this time, the fixing plate fixing column 421 of the fixing plate 42 is in the fixing plate fixing groove 52 of the lens frame 5, and the fixing plate sliding protrusion 422 of the fixing plate 42 slides from the preset groove of the fixing plate outer frame 41 into the fixing plate sliding groove 53 on the lens frame 5. At this time, the fixing plate 42 surrounds the lens 51 to prevent the lens 51 from contacting the external environment; when the lens 51 is damaged, it is prevented from causing damage to other objects.

[0097] Basic principles of the present invention:

[0098] like Fig.33 As shown, when the smart glasses are not in use, the temples 7 are folded and stored behind the frame 1 for easy storage; the rotating member 2 is located in front of the frame 1 and contacts the front end surface of the frame 1 to prevent dust and the like from entering the frame 1;

[0099] like Fig.34 As shown, when the smart glasses are worn, the temples 7 are rotated to a position that is convenient for wearing, and at the same time, the wearer pulls the rotating rod 14 to one side through the anti-slip knob 141, and the elastic member 142 inside the rotating rod 14 is extended. Then, the wearer rotates the rotating rod 14 to a suitable angle, loosens the rotating rod 14, and the elastic member 142 recovers and contracts, so that the fixing block 143 of the rotating rod 14 enters other rotating rod fixing grooves 19 around the rotating rod 14, fixes the rotating rod 14, and fixes the rotating member 2 at the same time. At this time, the rotating member 2 is above the frame 1, and the rotating member 2 does not block the lens 51, but can also block direct sunlight, which is more convenient for use when going out for sightseeing.

[0100] like Fig.35 As shown, when the smart glasses need to be stored after wearing, the wearer connects the fixed sheet storage device 3 placed in the bag with the sliding connection groove 22 on the rotating member 2 through the sliding connection block 31, so as to fix the fixed sheet storage device 3 on the rotating member 2. Then, the wearer pulls the rotating rod 14 to one side through the anti-slip knob 141, and the elastic member 142 inside the rotating rod 14 stretches. The wearer rotates the rotating rod 14 to a certain angle, and the fixed sheet storage device 3 contacts the upper end surface of the frame 1. The wearer pushes the rotating rod 14, and the elastic member 142 contracts. The fixed block 143 of the rotating rod 14 enters another rotating rod fixing groove 19 to fix the rotating rod 14.

[0101] When the rotating rod 14 completes its rotation, the gear 144 of the rotating rod 14 drives the rack 154 inside the frame 11 to move. When the rack 154 moves to one side, it squeezes the baffle switch 152 of the baffle device 15 inside the frame 11. When the baffle switch 152 is squeezed, the baffle device 15 controls the telescopic baffle 153 to retract from the baffle slot 16 of the frame 11 toward the inside of the baffle device 15, so that the fixed sheet slot 114 on the upper end surface of the frame 11 is connected to the outside.

[0102] Subsequently, the fixed sheet storage device 3 contacts the upper end surface of the frame 1, and the pushing piece 13 at the upper end of the frame 1 enters the pushing piece groove 32 of the fixed sheet storage device 3, squeezing the fixed sheet switch 321, so that the fixed sheet telescopic piece 342 of the fixed sheet control device 34 located inside the fixed sheet storage device 3 stretches a certain distance and then shrinks and recovers. Due to the extension of the fixed sheet telescopic piece 342, the fixed sheet accommodating device 4 is driven to enter the fixed sheet groove 114 of the frame 1. As the fixed sheet accommodating device 4 moves downward, the connecting plate 63 of the pushing piece 6 will enter the sliding groove 411 of the pushing device of the fixed sheet accommodating device 4. When the fixed sheet accommodating device 4 moves downward, the connecting plate 63 of the pushing piece 6 will enter the sliding groove 411 of the pushing device of the fixed sheet accommodating device 4. When the sheet accommodating device 4 moves to the lowest end, the fixed sheet telescopic member 342 of the fixed sheet control device 34 is in the process of extending, and the limit block switch 345 is squeezed by the bottom of the clamping groove 412 of the fixed sheet accommodating device 4, so that the fixed sheet limit block 344 is retracted into the inside of the fixed sheet clamping member 343; then the fixed sheet telescopic member 342 performs a retracting movement, at which time the fixed sheet limit blocks 344 on both sides of the fixed sheet clamping member 343 are retracted, and the fixed sheet clamping member 343 loses connection with the fixed sheet accommodating device 4, and the fixed sheet accommodating device 4 remains in the fixed sheet groove 114 of the frame 1, and the fixed sheet clamping member 343 retracts alone;

[0103] like Fig.36 As shown, the wearer then continues to rotate the rotating rod 14 to make the rotating rod 14 rotate in the opposite direction (restore), so that the fixed sheet storage device 3 rotates with the rotating member 2 until it contacts with the front end surface of the frame 1 (restores); due to the reverse rotation of the rotating rod 14, the gear 144 of the rotating rod 14 drives the rack 154 to move in the opposite direction, and the rack 154 loses the pressure on the baffle switch 152, and the baffle device 15 drives the telescopic baffle 153 to extend into the baffle slot 16 of the frame 1, and fixes the fixed sheet accommodating device 4 inside the frame 1, on both sides of the lens 51, to prevent the lens 51 from being scratched, and the smart glasses can be stored in any position without worrying about the problem of scratching the lens 51;

[0104] like Fig.37As shown, when the lens 51 is damaged and needs to be replaced, when the fixed sheet storage device 3 rotates with the rotating member 2 to contact the upper end surface of the frame 1, the fixed sheet accommodating device 4 enters the fixed sheet groove 114 of the frame 1, and after the fixed sheet telescopic member 342 contracts, the wearer can slide the sliding switches 18 located on both sides of the frame 1 (slide the sliding switch 18 on the damaged side of the lens 51 to the bottom) to extend the pushing rod 62 of the pushing device 6 for a distance. Since the connecting plate 63 of the pushing device 6 is in the groove of the fixed sheet 42 (the same groove as the pushing device sliding groove 411 of the fixed sheet accommodating device 4), the fixed sheet 42 is driven to move toward the lens frame 5, and the fixed sheet fixing column 421 of the fixed sheet 42 is in the fixed sheet fixing groove 52 of the lens frame 5, and the fixed sheet sliding protrusion 422 of the fixed sheet 42 slides from the preset groove of the fixed sheet outer frame 41 into the fixed sheet sliding groove 53 on the lens frame 5. At this time, the fixed sheet 42 is combined with the lens frame 5 (as shown in FIG. Fig.31 The wearer then drives the lens fixing block 541 to move to one side by means of the toggle block 542, thereby squeezing the spring 543 and contacting the connection state of the lens frame 5 and the frame 1. The wearer then takes out the combined lens frame 5 and the fixing plate 42, and inserts the spare lens frame 5 (with the same structure as the taken-out lens frame 5 and the fixing plate 42) prepared for replacement into the frame 1, so that the lens fixing device 54 of the spare lens frame 5 is combined with the lens fixing groove 17 of the frame 1, and fixes the spare lens frame 5 in the frame 1. As the spare lens frame 5 is inserted, the connecting disk 63 of the pushing device 6 enters the groove of the fixing plate 42 of the spare lens frame 5. The wearer then slides the sliding switch 18 upward to retract (restore) the pushing rod 62, and the connecting disk 63 drives the new fixing plate 42 to enter the interior of the fixing plate outer frame 41. The wearer then rotates the rotating rod 14 to a certain angle, and then rotates it back. The fixing piece switch 321 inside the fixing piece storage device 3 is squeezed again, so that the fixing piece telescopic member 342 is extended for a distance and then retracted. During the extension process of the fixing piece telescopic member 342, the limit block switch 345 on the fixing piece clamping member 343 is squeezed, so that the fixing piece limit block 344 extends from the fixing piece clamping member 343 and enters the limit groove 413 of the fixing piece. Subsequently, during the contraction process, the fixing piece telescopic member 342 will drive the fixing piece accommodating device 4 to move upward until the fixing piece accommodating device 4 is completely retracted into the fixing piece storage device 3. The wearer rotates the rotating rod 14 in the opposite direction to a suitable position. Due to the reverse rotation of the rotating rod 14, the rack 154 is driven to move in the opposite direction. The rack 154 loses control of the baffle switch 152, and the baffle device 15 extends the telescopic baffle 153 into the baffle groove 16, completing the replacement of the lens 51. For the convenience of wearing, the wearer can remove the fixing piece storage device 3 and place it in the storage bag.

[0105] Embodiment 1:

[0106] like Fig.38 , Fig.39 , Fig.40 As shown, the rotating rod 14 is arranged on both sides of the frame 1, and the ends of the rotating rod 14 are provided with gears 144; two baffle devices 15 are arranged inside the frame 1 to control the baffle slots 16 on both sides respectively;

[0107] Since the rotating rods 14 are provided with two on the left and right sides, the positions of the rotating members 2 on both sides can be adjusted respectively, which is convenient for use in different environments;

[0108] At the same time, the lenses 51 on both sides can be replaced separately.
