Description

Technical Field

[0001] This utility model relates to the field of companion robot technology, and in particular to a strap adjustment mechanism. Background Technology

[0002] Companion robots are robots with artificial intelligence and perception capabilities. Guide robot companion robots use ultrasonic sensors to continuously detect the distance parameters between themselves and obstacles. When the distance exceeds a certain value, they will vibrate to remind the user. When a blind person falls, because the guide robot companion is worn on the chest, the ultrasonic sensor is likely very close to or touching the ground, so the detected distance is very small. At this time, the robot will emit a distress sound through the connected sound sensor to call for help, which can eliminate the concerns of passersby to help. The guide robot companion is placed in front of the backpack.

[0003] Currently, adjusting the length of the shoulder straps is difficult for blind people because they cannot see and cannot adjust them as quickly as sighted people. Furthermore, because the shoulder straps are relatively smooth, the backpack may slip off the shoulders when a blind person bends over, causing it to fall off and affecting its use. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the problems in the above or existing technologies, such as blind people not being able to see the straps and the inconvenience of adjusting the length of the straps when they are placed in front of the body, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a strap adjustment mechanism.

[0007] To solve the above technical problems, the present invention provides the following technical solution: a shoulder strap adjustment mechanism, comprising a backpack component, including a backpack body, a handle disposed above the backpack body, shoulder straps disposed on both sides of the backpack body, a back cover disposed on one side of the backpack body, and support plates disposed on both sides below the backpack body;

[0008] An adjustment component, disposed below the backpack component, includes a winding assembly, a limiting assembly disposed on the winding assembly, a locking assembly disposed on one side of the limiting assembly, a sliding assembly disposed below the winding assembly, and a wave tapping assembly disposed outside the winding assembly.

[0009] As a preferred embodiment of the shoulder strap adjustment mechanism of this utility model, the winding assembly includes a first groove disposed on both sides below the backpack body, a rotating shaft disposed inside the backpack body, a limiting plate disposed on both sides of the outer wall of the rotating shaft, and a rotating block disposed on both sides of the rotating shaft.

[0010] As a preferred embodiment of the shoulder strap adjustment mechanism of this utility model, the limiting component includes a second groove disposed in the lower middle part of the backpack body, a fixing plate disposed in the inner wall of the second groove, a first spring disposed in the top of the fixing plate, a movable plate disposed in the top of the first spring, a locking post disposed in the inner wall of the movable plate, a pulling rod disposed in the bottom of the locking post, a disc disposed in the upper part of the movable plate, and a locking groove disposed in the outer wall of the disc.

[0011] As a preferred embodiment of the strap adjustment mechanism of this utility model, the locking component includes a limiting groove disposed behind the moving plate, a limiting plate disposed below the moving plate, a fixing block disposed behind the limiting plate, and a tension spring disposed in front of the fixing block.

[0012] As a preferred embodiment of the strap adjustment mechanism of this utility model, the sliding component includes a fixed rod disposed behind the second groove, a fixed shaft disposed inside the fixed rod, and a rotating roller disposed on the outer wall of the fixed shaft.

[0013] As a preferred embodiment of the strap adjustment mechanism of this utility model, the wave-tapping component includes an impact block disposed above the fixed block, a first metal plate disposed in front of the impact block, gears disposed on both sides of the rotating shaft, and a second metal plate disposed above the gears.

[0014] The beneficial effects of the carrying strap adjustment mechanism of this utility model are as follows: This utility model pulls the pull rod downwards, causing the locking pin to move downwards and disengage from the locking slot, thus releasing the locking pin from its limit. At the same time, the locking pin moves the moving plate downwards. When the moving plate contacts the limiting plate, because one end of the limiting plate is sloped, the limiting plate will move outwards when the moving plate presses down on the limiting plate. Simultaneously, the tension spring is stretched. When the limiting groove aligns with the limiting plate, the limiting plate is inserted into the limiting groove through the reset action of the tension spring. During the reset, the impact block strikes the first metal piece and makes a sound, thus reminding the blind person that the limit has been set and preventing the moving plate from moving further, allowing for the next step of operation. At this time, the rotating block is rotated to make the rotating shaft rotate, thus allowing the carrying strap to retract. When the rotating shaft rotates, it drives the gear to rotate, and the gear will move the second metal piece to remind the blind person that adjustment is in progress, thereby enabling the blind person to make adjustments even when they cannot see.

[0015] In actual use, there is a problem that the straps will fall off from the sides when the bag is carried in front of the chest and the user bends over.

[0016] To solve the above-mentioned technical problems, this utility model also provides the following technical solution: a guide robot, including a shoulder strap adjustment mechanism, and a guide call component, including a shell disposed inside the backpack body, a speaker disposed at the bottom of the inner wall of the shell, a sound sensor disposed on one side of the inner wall of the shell, a vibration sensor disposed on one side of the sound sensor, and an ultrasonic sensor disposed on one side of the vibration sensor; and an anti-drop component, including a pop-out component disposed behind the shoulder strap, unlocking components disposed on both sides of the pop-out component, and a locking component disposed on one side of the pop-out component.

[0017] As a preferred embodiment of the guide robot of this utility model, the pop-out component includes a card holder disposed behind the shoulder strap, a pop-out spring disposed on one side of the inner wall of the card holder, and a pop-out plate disposed at one end of the pop-out spring.

[0018] As a preferred embodiment of the guide robot of this utility model, the unlocking component includes a movable groove disposed on both sides of the inner wall of the card sleeve, a movable block disposed on the inner wall of the movable groove, and a pressing block disposed at one end of the movable block.

[0019] As a preferred embodiment of the guide robot of this utility model, the locking component includes a locking block disposed on the inner wall of the locking sleeve, telescopic grooves disposed at both ends of the locking block, a telescopic spring disposed at one end of the telescopic groove, a limiting block disposed at one end of the telescopic spring, and a connecting strip disposed at one end of the locking block.

[0020] The beneficial effects of this utility model of a guide robot for the blind are as follows: When the backpack is placed in front of the chest, the blind person uses their hands behind their back to feel for the card holder and the card block, and then places the card block into the card holder. At this time, because one end of the limiting block is sloping, it will squeeze the limiting block and make it retract into the telescopic groove. When the limiting block moves into the range of the moving groove, the restriction on the limiting block is released, and the limiting block is popped out by the reset action of the telescopic spring, so that the card block can be limited. This connects the two straps together, preventing the straps from falling off when the blind person bends over, and keeping the backpack tightly bound to the front of the body.

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0038] Example 1

[0039] Reference Figures 1 to 8 This is the first embodiment of the present invention, which provides a shoulder strap adjustment mechanism that enables blind people to adjust the backpack even when they cannot see. It includes a backpack component 100, comprising a backpack body 101, a handle 102 disposed above the backpack body 101, shoulder straps 103 disposed on both sides of the backpack body 101, a back cover 105 disposed on one side of the backpack body 101, and support plates 104 disposed on both sides below the backpack body 101; and an adjustment component 200 disposed below the backpack component 100, including a winding assembly. 201. A limiting component 202 disposed on the winding assembly 201, a locking component 203 disposed on one side of the limiting component 202, a sliding component 204 disposed below the winding assembly 201, and a wave tapping component 205 disposed on the outside of the winding assembly 201; the winding assembly 201 includes a first groove 201a disposed on both sides below the backpack body 101, a rotating shaft 201b disposed inside the backpack body 101, a limiting disc 201c disposed on both sides of the outer wall of the rotating shaft 201b, and rotating blocks 201d disposed on both sides of the rotating shaft 201b.

[0040] Specifically, the carrying strap 102 is fixedly installed on the top of the backpack body 101, allowing the backpack body 101 to be carried by the carrying strap 102. The shoulder straps 103 are fixedly installed on both sides of the top of the backpack body 101, allowing the backpack to be carried on the front of the blind person by the shoulder straps 103. The back shell 105 is fixedly installed on one side of the backpack body 101. The support plate 104 is fixedly installed on both sides of the bottom of the backpack body 101, allowing the backpack body 101 to be placed vertically on a flat surface by the support plate 104.

[0041] The first groove 201a is formed on both sides below the backpack body 101. The rotating shaft 201b is rotatably disposed inside the backpack body 101 and passes through the backpack body 101. The limiting plate 201c is fixedly disposed on both sides of the rotating shaft 201b and located inside the first groove 201a. The limiting plate 201c is symmetrically arranged about the center line of the first groove 201a. The rotating block 201d is fixedly disposed on both sides of the outer wall of the rotating shaft 201b. The outer wall of the rotating block 201d is provided with multiple arc-shaped grooves, which can increase the friction and prevent slippage during rotation. When the rotating block 201d is rotated, the rotating shaft 201b rotates at the same time, so that the shoulder strap 103 is rolled up between the rotating shaft 201b and the limiting plate 201c, thereby adjusting and shrinking the shoulder strap 103.

[0042] Furthermore, the limiting component 202 includes a second groove 202a disposed in the lower middle part of the backpack body 101, a fixing plate 202b disposed in the inner wall of the second groove 202a, a first spring 202c disposed at the top of the fixing plate 202b, a moving plate 202d disposed at the top of the first spring 202c, a locking post 202e disposed in the inner wall of the moving plate 202d, a pulling rod 202f disposed at the bottom of the locking post 202e, a disc 202g disposed above the moving plate 202d, and a locking groove 202h disposed in the outer wall of the disc 202g; the locking component 203 includes a limiting groove 203d disposed in one side of the moving plate 202d, a limiting plate 203a disposed below the moving plate 202d, a fixing block 203c disposed behind the limiting plate 203a, and a tension spring 203b disposed in front of the fixing block 203c.

[0043] The second groove 202a is located in the lower center of the backpack body 101. A fixing plate 202b is fixed to the inner wall of the second groove 202a. A first spring 202c is fixed to the top of the fixing plate 202b. A moving plate 202d is fixed to the top of the first spring 202c. A locking post 202e is fixed to the inner wall of the moving plate 202d and passes through the fixing plate 202b. When the locking post 202e moves, the fixing plate 202b remains stationary. A pulling rod 202f is fixed to the bottom end of the locking post 202e. The pulling rod 202f is stretched to allow movement. 02f moves downward, taking the locking pin 202e downward and the moving plate 202d downward. At the same time, the first spring 202c is compressed. The disc 202g is set above the moving plate 202d and fixed to the outer wall of the rotating shaft 201b. The slot 202h is opened on the outer wall of the disc 202g, and the locking pin 202e is set in the slot 202h. When rotation is required, the locking pin 202e is moved away from the slot 202h, thereby releasing the restriction on the disc 202g and allowing the disc 202g to rotate.

[0044] A limiting groove 203d is formed behind the movable plate 202d. A limiting plate 203a is positioned below the movable plate 202d. A fixing block 203c is fixedly positioned behind the limiting plate 203a. A tension spring 203b is fixedly positioned in front of the fixing block 203c and is also fixedly positioned behind the backpack body 101. The tension spring 203b is positioned on the outside of the limiting plate 203a. When the movable plate 202d moves downward, it will compress the limiting plate 203a. One end is sloped, so during the extrusion process, the limiting plate 203a will move outward and stretch the tension spring 203b. When the limiting groove 203d is aligned with the limiting plate 203a, the limiting plate 203a is locked into the limiting groove 203d by the reset action of the tension spring 203b, which limits the moving plate 202d and prevents it from moving. After the winding is finished, the limiting plate 203a is pulled out of the limiting groove 203d by pulling the fixing block 203c, thus releasing the limitation on the moving plate 202d.

[0045] When the backpack body 101 is placed in front of a blind person, to facilitate the adjustment of the length of the shoulder strap 103, the person holds the pull rod 202f and moves it downwards. The pull rod 202f moves the locking post 202e downwards, and simultaneously moves the moving plate 202d downwards, compressing the first spring 202c. At this time, the locking post 202e moves out of the range of the locking groove 202h. As the moving plate 202d moves downwards, it will press the limiting plate 203a. Since one end of the limiting plate 203a is sloping, pressing the limiting plate 203a downwards will cause the limiting plate 203a to move outwards, while stretching the tension spring 203b. When the limiting groove 203d and the limiting plate 203a are aligned, the resetting action of the tension spring 203b will cause the limiting plate 203a to engage with the limiting groove 203. Within d, the movable plate 202d is limited. At this time, the rotating block 201d rotates the rotating shaft 201b and winds up the shoulder strap 103. After winding up a certain length, the fixed block 203c is pulled to move the limiting plate 203a outward, releasing the limitation on the movable plate 202d. Then, the first spring 202c resets the movable plate 202d and moves the locking pin 202e back into the locking slot 202h, limiting the disc 202g. Since the disc 202g and the rotating shaft 201b are fixed, the rotating shaft 201b can be limited to prevent it from rotating. This makes it convenient for blind people to adjust the shoulder strap 103 even when they cannot see, making it easier for them to use.

[0046] Example 2

[0047] Reference Figures 1-10This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a shoulder strap adjustment mechanism, which solves the problem of wear on the shoulder strap 103 during the adjustment process. It includes the sliding component 204, which includes a fixed rod 204a disposed behind the second groove 202a, a fixed shaft 204b disposed inside the fixed rod 204a, and a rotating roller 204c disposed on the outer wall of the fixed shaft 204b.

[0048] Specifically, the fixing rod 204a is fixedly disposed behind the second groove 202a, and the fixing rod 204a is symmetrically arranged about the center of the second groove 202a. Since there are two second grooves 202a, the fixing rods 204a are also arranged in two sets. The fixing shaft 204b is fixedly disposed on the inner side of the fixing rod 204a, and the rotating roller 204c is rotatably disposed on the outer wall of the fixing shaft 204b and abuts against the shoulder strap 103. When the shoulder strap 103 is contracted and adjusted, it will rotate the rotating roller 204c. Therefore, during adjustment, the shoulder strap 103 can be prevented from wearing and the shoulder strap 103 can be prevented from breaking during use.

[0049] Furthermore, the wave impact component 205 includes an impact block 205a disposed above the fixed block 203c, a first metal plate 205b disposed in front of the impact block 205a, gears 205c disposed on both sides of the rotating shaft 201b, and a second metal plate 205d disposed above the gears 205c.

[0050] It should be noted that the impact block 205a is fixedly mounted on the fixed block 203c, and the first metal plate 205b is located in front of the impact block 205a. At the same time, the first metal plate 205b is fixedly mounted behind the backpack body 101. When the fixed block 203c performs a reset movement and quickly rebounds, the impact block 205a will collide with the first metal plate 205b, thereby producing a sound and reminding the blind user to proceed to the next operation. The gear 205c is fixedly mounted on both sides of the rotating shaft 201b, and the second metal plate 205d is located above the gear 205c. The second metal plate 205d is also fixedly mounted on both sides of the backpack body 101. When the rotating shaft 201b rotates, it drives the gear 205c to rotate. When the gear 205c rotates, it will move the second metal plate 205d, thus producing a sound and reminding the blind user that the adjustment is being performed.

[0051] When adjusting the carrying strap 103, to prevent wear and breakage during use, a rotating roller 204c contacts the carrying strap 103. The rotating roller 204c also rotates when the carrying strap 103 is adjusted, thus preventing wear. During adjustment, the rotating shaft 201b drives the gear 205c to rotate, which in turn moves the second metal plate 205d, producing a sound that alerts the blind person to the adjustment operation. Similarly, the impact block 205a also produces a sound when it strikes the first metal plate 205b, further prompting the blind person to proceed to the next step.

[0052] Example 3

[0053] Reference Figures 11-13 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a guide robot for the blind, which solves the problem that the shoulder strap 103 may fall off when a blind person bends over, causing the backpack body 101 to fall off. It includes the shoulder strap adjustment mechanism in the above embodiment, which includes a guide call component 300, including a shell 301 disposed inside the backpack body 101, a speaker 302 disposed at the bottom of the inner wall of the shell 301, a sound sensor 303 disposed on one side of the inner wall of the shell 301, a vibration sensor 305 disposed on one side of the sound sensor 303, and an ultrasonic sensor 304 disposed on one side of the vibration sensor 305; and an anti-fall component 400, including a pop-out component 401 disposed behind the shoulder strap 103, unlocking components 402 disposed on both sides of the pop-out component 401, and a locking component 403 disposed on one side of the pop-out component 401.

[0054] Specifically, the outer shell 301 is located inside the backpack body 101. The speaker 302 is fixedly installed at the bottom of the inner wall of the outer shell 301. The sound sensor 303 is fixedly installed on one side of the inner wall of the outer shell 301. The vibration sensor 305 is located on one side of the sound sensor 303 and fixed to the inner wall of the outer shell 301. The ultrasonic sensor 304 is located on one side of the vibration sensor 305 and fixed to the inner wall of the outer shell 301. The ultrasonic sensor 304 can continuously detect and obtain the distance parameters to obstacles. When the distance measured by the ultrasonic sensor 304 is less than 50cm, the vibration motor sensor emits a signal. The vibration alerts the blind person to an obstacle, and an audio alert is also emitted. If the blind person accidentally falls and the injury is minor, they can get up on their own. However, if they are unable to move, since the robot is worn on their chest, the ultrasonic sensor 304 will likely be very close to or touching the ground, with a very small detection distance. Of course, we believe it is indestructible. In this case, the sound sensor 303 will be used to call for help. Moreover, to eliminate any concerns from passersby about providing assistance, the recorded distress call clearly states that the person fell on their own and is not faking an accident, and that they need help.

[0055] Furthermore, the pop-out component 401 includes a card sleeve 401a disposed behind the shoulder strap 103, a pop-out spring 401b disposed on one side of the inner wall of the card sleeve 401a, and a pop-out plate 401c disposed at one end of the pop-out spring 401b; the unlocking component 402 includes a moving groove 402c disposed on both sides of the inner wall of the card sleeve 401a, a moving block 402b disposed on the inner wall of the moving groove 402c, and a pressing block 402a disposed at one end of the moving block 402b; the locking component 403 includes a locking block 403a disposed on the inner wall of the card sleeve 401a, a telescopic groove 403b disposed at both ends of the locking block 403a, a telescopic spring 403c disposed at one end of the telescopic groove 403b, and a limiting block 403d disposed at one end of the telescopic spring 403c.

[0056] Among them, the card sleeve 401a is fixedly disposed at the rear of the shoulder strap 103, the pop-out spring 401b is fixedly disposed on one side of the inner wall of the card sleeve 401a, and the pop-out plate 401c is fixedly disposed at one end of the pop-out spring 401b. Through the elasticity of the pop-out spring 401b, the pop-out plate 401c can be popped outward, so that it can be quickly disassembled.

[0057] The movable groove 402c is formed on both sides of the inner wall of the sleeve 401a. The movable block 402b is slidably disposed on the inner wall of the movable groove 402c. The pressing block 402a is fixedly disposed on one end of the movable block 402b and passes through the sleeve 401a. By pressing the pressing block 402a inward, the pressing block 402a moves inward and moves the movable block 402b inward, which can release the locking state.

[0058] The locking block 403a is disposed on the inner wall of the sleeve 401a. The telescopic groove 403b is opened at both ends of the locking block 403a. The telescopic spring 403c is fixedly disposed at one end of the telescopic groove 403b. The limiting block 403d is fixedly disposed at one end of the telescopic spring 403c. The elasticity of the telescopic spring 403c can cause the limiting block 403d to pop out. The limiting block 403d is slidably disposed in the telescopic groove 403b. The telescopic groove 403b limits the limiting block 403d. The connecting strap 403e is fixedly disposed at one end of the locking block 403a and is also fixed to another back strap 103.

[0059] To prevent the backpack body 101 from falling off when the blind person bends over while it is worn in front, a locking block 403a is placed inside the locking sleeve 401a, while the limiting block 403d retracts into the telescopic groove 403b. When the locking block 403a is fully inside the locking sleeve 401a, the resetting action of the telescopic spring 403c causes the limiting block 403d to engage in the moving groove 402c. The moving groove 402c limits the limiting block 403d, thus preventing the carrying strap 103 from falling off the blind person when they bend over, thereby preventing the backpack body 101 from falling off. When removing the backpack, the blind person moves inward by squeezing the pressing block 402a. At this time, the pressing block 402a pushes the moving block 402b inward, causing the limiting block 403d to retract into the telescopic groove 403b. Then, the pop-out plate 401c moves outward and pops out through the reset action of the pop-out spring 401b, thereby popping the locking block 403a out of the card sleeve 401a. This makes it convenient for the blind person to unlock and remove the backpack. Furthermore, the locking block 403a and the card sleeve 401a are placed behind the shoulder strap 103 to improve comfort during use and prevent discomfort to the blind person's back.
