Description

Technical Field

[0001] This utility model relates to the field of Braille teaching and tactile rehabilitation assistive equipment technology, and in particular to a Braille touch training device. Background Technology

[0002] Braille is a tactile writing system designed specifically for visually impaired people. Through a regular combination of raised dots, blind people can obtain semantic information of text by touching it with their fingers. However, in practical applications, some visually impaired people have significantly reduced finger tactile sensitivity due to congenital or acquired nervous system damage (such as diabetic neuropathy, sequelae of stroke, spinal cord injury, etc.), making it difficult for them to accurately perceive and identify the raised shape and layout of Braille dots, which in turn hinders their literacy efficiency and learning process.

[0003] However, existing Braille training tools are mostly static Braille paper, Braille boards, and electronic reading devices. While they can meet basic usage needs, they have significant limitations: First, they are difficult to provide personalized adjustments and targeted training based on the differences in users' Braille learning stages and tactile abilities; second, they lack effective interactive training mechanisms, which is not conducive to users establishing active recognition awareness and tactile perception abilities; and third, for blind users with impaired tactile function, the threshold for Braille dot recognition is too high, resulting in poor training effectiveness.

[0004] In view of this, we have studied and improved the existing problems to provide a Braille touch training device. It features magnetic attraction, sliding pop-up, gear spring reset, replaceable dots, compact size, easy storage, and adaptability to multiple scenarios. The aim is to solve the problem and improve its practical value through this technology. Utility Model Content

Combined with a simplified top and bottom cover and sliding module, it has few parts, is easy to assemble and disassemble, and is compact in size, making it suitable for classroom and home use. Its dual reset and limit functions ensure safe and stable operation, meeting the personalized training needs of different learning stages. During operation, it stimulates tactile nerves, improving touch sensitivity and Braille reading ability. The dots are diverse in type and clearly distinguished by color, facilitating classification and organization. Furthermore, the dots can be magnetically absorbed, reducing the risk of loss, making it suitable for multiple user scenarios.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1 to 6 A Braille touch training device includes a device upper cover 1, the rear outer surface of the device upper cover 1 and the front outer surface of the device lower cover 2 are detachably connected by a housing fixing screw 22, a sliding support module 3 is detachably connected to the cavity between the device upper cover 1 and the device lower cover 2, and a replaceable Braille dot block 4 is connected to the front middle of the sliding support module 3 by a magnetic attraction structure.

[0027] The magnetic fixing structure composed of the strip magnet 21 on the lower cover and the embedded magnet 42 in the dot block can be replaced with a snap-on or slide rail embedded fixing structure, which can also achieve stable assembly and convenient disassembly of the Braille dots. The button reset spring 34 and the module reset spring 35 can be replaced with rubber springs or shape memory alloy wires, which provide a stable reset function through their elastic properties, adapting to different mechanical requirements. At the same time, the overall size of the device and the specifications of the Braille dots can be flexibly adjusted according to the learning progress. It can not only adapt to the installation requirements of more replacement Braille dots, but also match the usage scenarios of different training stages, covering everything from basic single character recognition to complex multi-character combination training, further expanding the comprehensiveness and practicality of training, and fully meeting the advanced learning needs of users.

[0028] The transmission mechanism composed of the linkage transmission gear 32 can be replaced by a push rod type, slide groove type or electric slide rail transmission structure to ensure smooth drive and stroke control of the sliding module. The upper cover 1 and the lower cover 2 of the device can be made of ABS plastic, silicone or lightweight aluminum alloy, etc., respectively to meet the needs of wear resistance, anti-slip or lightweight use, and adapt to multiple application scenarios.

[0029] Specifically, the sliding support module 3 includes a sliding module base 31. A linkage transmission gear 32 is movably connected to the lower middle part of the sliding module base 31. A module reset button 33 is movably connected to the outer wall of the linkage transmission gear 32. A button reset spring 34 is detachably connected to the middle of one side of the module reset button 33. A module reset spring 35 is detachably connected to the upper side of one side of the sliding module base 31. The replaceable Braille dot block 4 includes a dot block base 41. A dot block embedded magnet 42 is detachably connected to the right side opening of the dot block base 41. The sliding module base 31, linkage transmission gear 32, module reset button 33, and double springs 34 and 35 work together to achieve sliding, limiting, and automatic reset. The dot block base 41 is magnetically fixed by the embedded magnet 42. The overall structure has smooth linkage, convenient dot block replacement, and reliable reset and limiting, which can effectively help tactile training and safe use.

[0030] Specifically, a strip magnet 21 is bonded to the middle of the lower cover 2. When the dot block base 41 is inserted into the slot of the sliding module seat 31, the sliding module seat 31 provides precise guidance and positioning for the dot block base 41, so that the dot block embedded magnet 42 at the bottom of the dot block base 41 is precisely aligned with the strip magnet 21 of the lower cover and forms a magnetic attraction. At the same time, the slot of the sliding module seat 31 restricts the lateral displacement of the dot block base 41, achieving a dual positioning effect of "mechanical limit + magnetic fixation". This ensures that the dot block does not loosen or shift during training or movement of the sliding module seat 31. The advantages are reliable fixation, no complicated operation required for installation, and automatic adsorption and fixation after the dot block is inserted into the slot. The corner-cutting anti-foolproof design further reduces the risk of incorrect installation. Moreover, the magnetic structure does not affect the sliding function of the sliding module seat 31, and can smoothly realize the pop-out and replacement of the dot block. At the same time, the bonding connection method is simple and reliable, the magnet layout and the slot of the sliding module seat 31 are precisely matched, and no additional fixing parts are required, which takes into account the lightweight and practicality of the device.

[0031] Specifically, the lower center of the upper cover 1 and the lower cover 2 of the device are respectively provided with button mounting holes. The module reset button 33 passes through the button mounting hole and its outer surface is in contact with the hole wall. The hole wall limits the radial movement of the module reset button 33. The button mounting hole in the lower center of the upper and lower covers forms a radial limit on the module reset button, ensuring that the button can be smoothly pressed and rebounded along the axial direction, ensuring precise linkage with the gear, and improving the stability of operation.

[0032] Specifically, the inner surfaces of both ends of the upper cover 1 and the lower cover 2 are movably connected to the middle of both ends of the linkage transmission gear 32. The middle of the front end of the upper cover 1 is provided with a matching mounting hole corresponding to the replaceable Braille dot block 4. The dot block base 41 passes through the mounting hole and the middle of the sliding module seat 31 in sequence and is movably connected to both. The inner surfaces of both ends of the upper and lower covers provide movable support for the linkage transmission gear to ensure stable transmission. The mounting hole of the upper cover that matches the Braille dot block cooperates with the middle of the sliding module seat to provide assembly guidance and limit for the dot block, which ensures that the dot block is installed firmly without affecting the gear transmission and module sliding, taking into account both structural linkage and reliability of use.

[0033] Specifically, the middle of one side of the upper cover 1 and the lower cover 2 is detachably connected to the outer surface of one end of the button reset spring 34, and the inner surface of one side of the upper cover 1 and the lower cover 2 is detachably connected to the outer surface of one end of the module reset spring 35. The inner surfaces of both ends of the upper cover 1 and the lower cover 2 are movably connected to the middle of both ends of the linkage transmission gear 32. The upper cover 1 and the lower cover 2 are detachably fixed to the button reset spring 34 and the module reset spring 35 through the middle of one side and the inner surface of one side, respectively. The inner surfaces of both ends provide movable support for the linkage transmission gear 32, which provides a stable installation reference for the two springs and a smooth transmission guide for the gear, ensuring reliable coordination between the reset and transmission functions.

[0034] Specifically, the front center of the sliding module base 31 has several sets of slots for assembling the block base 41. Each set of slots has a guide chamfer at the port and a chamfer ramp at the corresponding position inside the slot. The block base 41 only has a chamfer structure at the lower left corner that matches the chamfer ramp. Its outer surface around the slots is precisely matched and detachably connected. The bottom of the block base 41 is magnetically attracted to the front surface of the strip magnet 21 of the lower cover by the embedded magnet 42 in the block. The assembly difficulty is reduced by the guide chamfer of the slot. The exclusive matching of the block chamfer and the chamfer ramp of the slot achieves a foolproof design, limiting the block to be inserted in only one direction. At the same time, the mechanical limit and magnetic fixation around the slot form a dual positioning. The advantage is that it can effectively prevent visually literate people from making directional mistakes during installation, ensuring the accuracy of the block's orientation. It can also make the block assembly stable and not easy to loosen or shift. The detachable design combined with the magnetic structure makes the block replacement convenient and efficient, greatly improving the ease of operation and reliability of the device.

[0035] Working principle: The Braille touch training device uses "magnetic positioning + mechanical linkage + elastic reset" as its core working mechanism. The overall structure consists of a closed cavity formed by the upper cover 1 and the lower cover 2 of the device, which are detachably connected by the housing fixing screws 22. Inside, there is a sliding support module 3, which consists of a sliding module seat 31, a linkage transmission gear 32, a module reset button 33, a button reset spring 34, and a module reset spring 35. Before use, the user needs to align the base 41 of the replaceable Braille dot 4 with the slot of the sliding module base 31 and insert it. Utilizing the strong magnetic attraction between the embedded magnet 42 at the rear of the dot base 41 and the strip magnet 21 in the middle of the lower cover 2, combined with the precise fit between the dot and the slot, the dot is doubly and stably positioned. This prevents displacement during use and accidental drop during touch and pressing. Simultaneously, the dot base 41 has a chamfered structure only at the lower left corner, and the corresponding position on the sliding module base 31 also has a matching chamfered ramp, forming a unique foolproof design. Structurally, this restricts the Braille dot to insertion into the slots of the upper cover 1 and the sliding module base 31 in only one direction. If attempted in reverse, it will not fit due to the inability to engage with the chamfered ramp, effectively preventing directional errors by sighted users, ensuring accurate dot orientation, and improving ease of use and reliability. When replacing the key block, the user pushes the sliding module base 31 to the right using the sliding button. The linkage transmission gear 32 at its lower end is then driven to rotate clockwise. During the rotation, the tip of the module reset button 33 is always locked in the tooth groove of the linkage transmission gear 32, and the tooth structure of the linkage transmission gear 32 exerts a continuous downward pushing force on the tip of the module reset button 33, so that the button is smoothly driven downward while maintaining engagement. During this stage, the button reset spring 34 is not idle, but continuously uses its own elasticity to firmly press against the module reset button 33, keeping it stably in the locked position in the tooth groove. This, together with the linkage transmission gear 32, forms a rigid limiting structure for the sliding module base 31, effectively preventing the linkage transmission gear 32 from rotating counterclockwise, and also preventing the sliding module base 31 from immediately rebounding after the module reset spring 35 is continuously compressed and stored. The compression process of the module reset spring 35 is entirely due to the continuous squeezing action of the sliding module base 31 when it moves to the right. At the same time, the chamfered structure at the lower left corner of the dot block base 41 will form a precise fit with the chamfered slope inside the sliding module base 31. As the sliding module base 31 moves to the right, the chamfer is forced to gradually move upward along the slope until the sliding module base 31 reaches the sliding limit position. At this point, the Braille dot block is automatically lifted and popped out of the slot. Unused dots blocks can be attracted to each other by their respective embedded magnets, which makes them easy to store and reduces the risk of loss.After removing the old dot block, the user needs to manually press the module reset button 33 to make it move slightly downwards against the elastic force of the button reset spring 34. At this time, the tip of the module reset button 33 will move to the edge of the tooth groove or completely disengage from the tooth groove meshing position, and the limiting constraint of the linkage transmission gear 32 will be released. Subsequently, the module reset spring 35, which has been compressed and stored energy, quickly releases its elastic potential energy, pushing the sliding module seat 31 to move smoothly to the left, while driving the linkage transmission gear 32 to rotate counterclockwise. After the sliding module seat 31 accurately returns to its initial position, the user releases the module reset button 33. The button quickly returns to its original position under the elastic force of the button reset spring 34, completing the entire reset process of the sliding module seat 31. Finally, the user aligns the new replaceable Braille dot block 4 with the slot and inserts it. Through magnetic attraction, it is once again stably positioned, successfully completing the entire dot block replacement and operation cycle.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
