DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-Figure 4 The present embodiment provides a multifunctional Braille keyboard, comprising a keyboard body 1 and a plurality of keys 2 arranged on the keyboard body 1, and also comprising a braille display 6 and a voice input module. The front end of the keyboard body 1 is provided with a mounting slot 7, and the braille display 6 can be detachably mounted in the mounting slot 7. A connector 601 is arranged at one end of the braille display 6 placed inside the mounting slot 7, and a connection interface 9 for the connector 601 to be inserted and connected is arranged on the inner wall of the mounting slot 7. The voice input module comprises a microphone 3 installed at the top rear end of the keyboard body 1 and a sound receiving device arranged inside the keyboard body 1. The microphone 3 and the sound receiving device are electrically connected to the control mainboard in the keyboard. Each key 2 are provided with Braille convex dots. By replacing the original English letters on the keyboard with Braille, and the keyboard format can be set according to the habits and needs of the blind, the operability of the keyboard is simplified. Through the setting of the microphone 3 and the sound receiving device, the blind can achieve barrier-free communication. Compared with the traditional ear-type microphone or the neck-hanging microphone, this design increases the portability and integrates the keyboard and the microphone. Through the setting of the dot display 6, the obstacle of the blind not being able to receive information conveniently is solved, which is helpful for the blind to use and can effectively solve the obstacle of the blind to communicate on the Internet, thereby alleviating the obstacle of the blind's psychological problems and helping them to go online to understand learning information.

[0024] It should be noted that the principle of the dot display 6 is that when we send information, the sent information will be displayed on the dot display in the form of Braille, and the received information will also appear on the dot display. The principle is to use pressure to change the force area so that the blind can perceive the Braille more clearly, triggering the varistor to work, thereby changing the resistance, current, and voltage, and then controlling the protrusion of the corresponding particles. This is a prior art and will not be elaborated on here.

[0025] In this embodiment, if Figure 1 and Figure 2 As shown, a receiving groove 4 is provided at the rear end of the top of the keyboard body 1, and the microphone 3 can be bent and stored in the receiving groove 4. When the Braille keyboard is not in use, the microphone 3 can be stored in the receiving groove 4 to reduce the size of the Braille keyboard and facilitate carrying and use. A first indicating protrusion 5 is provided at one end of the receiving groove 4 located on the top of the keyboard body 1. The first indicating protrusion 5 is used to indicate the position of the microphone 3 in the receiving groove 4, thereby facilitating the blind to take out the microphone 3 in the receiving groove 4 for use.

[0026] In this embodiment, if Figure 3 and Figure 4 As shown, a fixing structure is provided between the dot display 6 and the mounting groove 7, and the fixing structure includes a first fixing member 602 embedded and installed at one end of the dot display 6 close to the connector 601 and a second fixing member 10 embedded and installed on the inner wall of the mounting groove 7, the first fixing member 602 and the second fixing member 10 are adsorbed and connected, one of the first fixing member 602 and the second fixing member 10 is a first magnet, and the other of the first fixing member 602 and the second fixing member 10 is a second magnet, the first magnet and the second magnet have opposite magnetic poles and are adsorbed to each other, and the number of the first fixing member 602 and the second fixing member 10 is two symmetrical ones in this embodiment, when the dot display 6 is installed in the mounting groove 7, the first fixing member 602 and the second fixing member 10 are adsorbed to each other, thereby improving the fixing effect of the dot display 6, connecting the dot display 6 firmly, and preventing the dot display 6 from loosening and detaching from the mounting groove 7 during use, thereby affecting use.

[0027] In this embodiment, the inlet of the installation slot 7 is a flared structure, which helps the dot display 6 to be inserted into the installation slot 7 for connection and fixation.

[0028] In this embodiment, if Figure 1 and Figure 2 As shown, a storage box 8 is installed on one side of the keyboard body 1. The storage box 8 is used to store the dot display 6. The storage box 8 is a push-button box. When the Braille keyboard is not in use, the outer side of the storage box 8 can be pressed to pop out the storage box 8 from the keyboard body 1, thereby storing the dot display 6 in the storage box 8, reducing the volume of the Braille keyboard, making it easy to carry and use, and avoiding the problem of the dot display 6 being exposed to the outside and damaged. A second indication protrusion 801 is provided on the outer wall of the storage box 8, and the second indication protrusion 801 is used to indicate the position of pressing the storage box 8, so that the blind can use the pressing storage box 8.

[0029] In this embodiment, if Figure 3 As shown, a support strip 603 is fixedly bonded to the bottom of the braille display 6 , and the support strip 603 is used to fill the gap between the bottom of the braille display 6 and the desktop, thereby improving the stability of the braille display 6 .

[0030] Working principle: When in use, the English letters on the original keyboard are replaced with Braille, and the keyboard format can be set according to the habits and needs of the blind, which simplifies the operability of the keyboard. The microphone 3 and the sound receiving device are set to allow the blind to achieve barrier-free communication. Compared with traditional ear-type microphones or neck-hanging microphones, this design increases portability and integrates the keyboard and the microphone. The setting of the dot display 6 solves the obstacle of the blind not being able to receive information conveniently, which is helpful for the blind to use. When the Braille keyboard is not in use, the microphone 3 can be stored in the accommodating groove 4, the dot display 6 can be taken out of the installation groove 7, and then the outer side of the storage box 8 can be pressed to pop the storage box 8 out from the keyboard body 1, and the dot display 6 can be placed in the storage box 8 for storage, thereby reducing the size of the Braille keyboard and facilitating carrying and use.

[0031] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
