Technical Field

[0001] The invention relates to the technical field of visually impaired people, and in particular to a handheld anti-loss type electronic visual aid for visually impaired people. Background Art

[0002] When visually impaired people are walking, they need to use corresponding electronic visual aids and other equipment to assist them in walking. Therefore, the quality and operation of the electronic visual aids determine the safety of the visually impaired people. For example, the patent with publication number CN218868292U discloses a portable electronic visual aid, including an electronic visual aid body, a display panel is arranged on the front of the electronic visual aid body; a protective component is arranged on the front of the electronic visual aid body, the protective component includes a protective shell, a groove is arranged on the back of the protective shell, and the groove is sleeved on the outside of the display panel; a hinge mechanism is arranged at one end of the protective shell, and the hinge mechanism includes two hinge seats and a hinge plate. The protective shell is made of PC material, and the scientific name of PC is polycarbonate, which is a thermoplastic engineering plastic. PC material has strong impact resistance, good toughness, high transparency, non-toxicity, and is easy to process and mold. The display panel can be shielded and protected by the protective shell; Another example is a patent with publication number CN204442561U, which discloses an electronic visual aid with a voice navigation device, including a shell, an LCD display screen, a power switch, a zoom-in button, a zoom-out button, a color-changing button, a freeze screen button, an HDMI interface, a power interface, a USB upgrade interface and a rechargeable lithium battery, and a voice control circuit board is arranged in the shell. The voice control circuit board integrates a digital signal processor, a microcontroller, a voice generator and a speaker. A camera is also arranged on the shell. The existing electronic visual aid used by people with low vision is equipped with a voice navigation function, so that people with low vision can start corresponding voice prompts when reading, studying, entertaining and other activities, and can correctly operate the electronic visual aid to obtain the required functions. The structure is simple and easy to use. For example, the patent with publication number CN201114346Y is an electronic vision aid. The vision aid includes a camera, a signal processing device, and a signal output port. The vision aid is designed in the shape of a mouse for portability. The vision aid itself is equipped with a lighting lamp for illuminating and specifying the target. The output port can have both video output and USB output or one of them can be selected according to the user's needs. The camera can be fixed on the device or designed to be rotatable. The vision aid has the characteristics of easy portability, adjustable magnification, self-focusing, self-lighting, adjustable background color, video or USB output, and can choose TV or computer as display, and can be used for reading or writing by people with low vision; Most of the above-mentioned prior arts have improved their overall structure. However, during the use of the existing electronic visual aids for visually impaired people, since most of the electronic visual aids are directly handheld structures, when the visually impaired people accidentally release the hand device and it falls, it is impossible for the user to find it quickly, resulting in certain usage limitations.

[0005] Furthermore, the auxiliary positioning structure is provided with a spherical nested docking piece, and the spherical nested docking piece is fixedly connected to the upper and lower ends of the connecting docking rod, and the two spherical nested docking pieces are respectively docked with the handheld electronic visual aid body and the inner side of the docking reserved component to form a nested structure.

[0006] Furthermore, a nested connecting support is nested and installed at the lower end of the docking reserved component, and an abutment docking piece is fixedly connected to the outer side of the nested connecting support, and the abutment docking piece corresponds to the outer side position of the connecting docking rod; a return spring is fixedly connected to the outer side of the nested connecting support, and the return spring is docked with the outer side position of the docking reserved component.

[0007] Furthermore, the handheld electronic visual aid body is connected to the docking reserve component and the wrist docking component through the docking rod, and cooperates with the spherical nested docking piece connected to the end of the docking rod to form a multi-directional movable structure.

[0008] Furthermore, when the connecting docking rod is pressed and moved inward, it will pre-contact the abutment piece, and the abutment piece will be forced to drive the nested connecting support member to move inward along the inner side of the docking reserved component, and the nested connecting support member will form an elastic movable structure along the outer side of the docking reserved component through a reset spring.

[0012] Furthermore, the vertically docking corrugated bladder assembly supplies the interior of the horizontally docking corrugated bladder assembly through the supply hose assembly, and the horizontally docking corrugated bladder assembly pushes the fitting flexible member to bulge outward and deform.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The handheld anti-dropout electronic visual aid for visually impaired people is provided with an auxiliary positioning structure, and the docking state of the handheld electronic visual aid body is processed to prevent dropout through the auxiliary positioning structure. After the user wears the handheld electronic visual aid body through the wrist docking assembly, the user can hold the handheld electronic visual aid body to avoid obstacles. Through the connecting docking rods with spherical nested docking pieces at both ends, the handheld electronic visual aid body and the wrist docking assembly can be perfectly moved in multiple directions according to needs without dead angles, meeting the user's various operation hand-holding needs, thereby better performing the anti-dropout visual aid work. Furthermore, a positioning support structure is provided, through which the inner side of the wrist docking assembly is supported and positioned. When the handheld electronic visual aid body held by the user accidentally falls off, it will move downward by gravity, thereby driving the connecting docking rod to be synchronously forced to move inward along the lower end of the docking reserved assembly, and then pressurizing the contacting nested connecting support member and the abutting docking piece, so that the nested connecting support member moves along the outer side of the docking reserved assembly through the reset spring, and the nested connecting support member drives the fitting docking connector to slide downward along the inner side of the accommodating reserved groove through the corresponding traction rope, and pressurizes the contacting vertical docking corrugated liquid capsule assembly, and the vertical docking corrugated liquid capsule assembly supplies the inside of the horizontal docking corrugated liquid capsule assembly through the supply hose assembly, and the fitting flexible member is pushed to bulge outward and deform through the horizontal docking corrugated liquid capsule assembly, thereby compressing the support space inside the wrist docking assembly, and realizing the adaptive anti-falling positioning processing operation; Furthermore, the structure of traditional electronic vision aids, which are mostly handheld, is avoided. When a visually impaired person accidentally lets go of the device and drops it, it will not fall directly to the ground, but will be adaptively buckled on the user's wrist, thereby improving the user's experience and desirability.
