Description
Technical Field
[0001] This utility model relates to the field of elevator accessories technology, and in particular to an elevator floor announcer for the blind. Background Technology
[0002] As society pays more attention to accessible facilities, elevator floor announcers have become a basic component of some elevators, but some older elevators still do not have this function.
[0003] To accurately determine the current floor, existing elevator announcement systems typically require one announcement per elevator. The announcement is installed inside the elevator and is equipped with a floor reading module. It can remotely connect to the elevator's lifting and lowering control structure via a wireless connection module to determine the current floor based on the elevator's lifting and lowering value.
[0004] When blind people travel, if they encounter old elevators without floor announcers, or if they arrive at an unfamiliar building, they will have difficulty operating the elevator because they are unsure of the location and configuration of the announcer. This causes inconvenience for blind people when taking elevators. Utility Model Content
[0005] The main purpose of this utility model is to provide an elevator floor announcer for the blind, which aims to reduce the cost of the announcer, make it portable, and enable the blind to travel conveniently.
[0006] To achieve the above objectives, this utility model proposes an elevator floor announcer for the blind, comprising an announcer body, the announcer body having a protective shell, the protective shell having an installation cavity, the installation cavity having a main control circuit board, the main control circuit board being equipped with a floor positioning sensor, and the main control circuit board being connected to a battery.
[0007] The protective casing is equipped with button components and a microphone, both of which are electrically connected to the main control circuit board.
[0008] In one embodiment of this application, the protective shell includes an upper shell and a lower shell, and the button assembly includes a mechanical button electrically connected to the main control circuit board and an elastic button passing through the upper shell and linked to the mechanical button.
[0009] The protective shell is provided with a sound-emitting hole, and the microphone is installed at the corresponding sound-emitting hole.
[0010] In one embodiment of this application, the protective shell is provided with a connecting structure, the connecting structure including a first connecting block and a second connecting block respectively connected to the upper shell and the lower shell, the second connecting block having a reinforcing block protruding toward the first connecting block, and the first connecting block having a positioning and locking groove relative to the reinforcing block;
[0011] When the upper and lower shells are assembled together, the reinforcing block passes through the positioning and locking groove.
[0012] In one embodiment of this application, the end of the protective shell away from the connecting structure is provided with a charging connection portion relative to the battery. The charging connection portion passes through the protective shell and is electrically connected to the battery.
[0013] In one embodiment of this application, a sealing structure is provided between the outer periphery of the upper housing and the outer periphery of the lower housing. The end face of the sealing structure facing away from the connecting cavity is provided with a locking rod and a locking part. The locking rod and the locking part are respectively provided on the upper housing and the lower housing.
[0014] When the upper and lower housings are assembled together, the locking rod passes through the locking part.
[0015] In one embodiment of this application, the main control circuit board has multiple vias, the protective shell has an open guide connection portion facing the vias, and the protective shell also has a mating connection portion that cooperates with the guide connection portion. The guide connection portion, vias, and mating connection portion are fastened together by fasteners.
[0016] In one embodiment of this application, the lower housing is provided with a mounting groove relative to the microphone, the mounting groove surrounds the sound transmission hole, one end of the microphone is connected to the main control circuit board, and the other end is connected to the mounting groove.
[0017] In one embodiment of this application, the protective shell is provided with a display module, which is electrically connected to the main control circuit board.
[0018] By adopting the above technical solution, this utility model has the following advantages:
[0019] 1. The elevator floor announcer for the blind is a portable elevator floor announcer. The protective shell of the announcer has a mounting cavity inside to protect the internal components and main control circuit board. The main control circuit board is equipped with a battery, which can be a replaceable or rechargeable battery, making the announcer portable. The protective shell also has a connection structure, which can be a connection hole on the outer edge of the shell for attaching a lanyard. Users can also use a detachable hook to connect to the connection hole, and the hook has a lanyard. Users can use the lanyard to hang the announcer around their neck or on other parts of their body. The announcer uses a battery structure, and both rechargeable and detachable batteries can be used with the connection structure, making the entire announcer easy to carry and use. Blind users can carry the announcer into any elevator and use it, greatly improving the flexibility of the announcer's use.
[0020] 2. The main control circuit board is connected to a button assembly and a microphone. Each button on the button assembly has Braille markings, allowing the user to select the button based on the Braille markings. The user then inputs the desired floor into the main control circuit board via the button assembly. The main control circuit board is configured to repeat the input floor name once, enabling the blind user to confirm the correctness of the input. Once confirmed, the elevator operates normally. As the elevator approaches the desired floor, the main control circuit board uses a floor positioning sensor to determine the current floor's location. When the system determines that it is about to arrive, it uses the microphone to announce the approach and exit of the elevator. Through the coordinated operation of these components, the blind can travel flexibly and stably.
[0021] 3. The floor positioning sensor connected to the main control circuit board uses a sensor module. This module only requires power to function properly. The sensor module and the announcer are directly connected, allowing the main control circuit board to receive external physical information to determine the current floor. The most noticeable change in air pressure during elevator ascent and descent is obvious and objective. The sensor module uses both a pressure sensor and a temperature sensor. The pressure sensor collects air pressure data and determines the current floor based on the pressure difference. Since air pressure often changes uniformly due to temperature variations, the main control circuit board can use data from the temperature sensor... The air pressure difference is adjusted to indicate whether a floor has risen or fallen by one floor. After adjusting the internal parameters, the main control circuit board can use the air pressure sensor to determine the current floor. Because these sensors collect objective physical data and only need to be powered on to work, they can operate normally in enclosed environments where satellite signals cannot be accessed, such as in elevators. This avoids reliance on traditional wireless signal positioning, improving the accuracy and reliability of positioning. Users can easily use the broadcaster when entering any elevator. The broadcaster has a simple structure and can be adapted to different buildings, effectively reducing the cost of elevator installation and use, and enabling blind people to travel more safely.

[0029] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0031] Reference Figures 1 to 4 To achieve the above objectives, this utility model proposes an elevator floor announcer for the blind, comprising an announcer body 1, the announcer body 1 having a protective shell 2, the protective shell 2 having an installation cavity 11, the installation cavity 11 having a main control circuit board 4, the main control circuit board 4 being equipped with a floor positioning sensor, and the main control circuit board 4 being connected to a battery.
[0032] The protective shell 2 is equipped with a button assembly 6 and a microphone 7, both of which are electrically connected to the main control circuit board 4.
[0033] The elevator floor announcer for the blind is a portable elevator floor announcer. The protective shell 2 of the announcer has a mounting cavity 11 inside, which protects the internal components and the main control circuit board 4. The main control circuit board 4 is equipped with a battery, which can be a replaceable or rechargeable battery, making the announcer portable. The protective shell 2 also has a connecting structure 3, which is a connecting hole on the outer edge of the protective shell 2 for attaching a lanyard. Users can also use a detachable hook to connect to the connecting hole, and the hook has a lanyard. Users can use the lanyard to hang the announcer around their neck or on other parts of their body. The announcer uses a battery structure, and both rechargeable and detachable batteries can be used with the connecting structure 3, making the entire announcer easy to carry and use. The entire announcer has a simple structure and high space utilization, which can minimize the size of the announcer and make it easy to carry. Blind users can carry the announcer into any elevator and use it, which greatly improves the flexibility of the announcer.
[0034] The main control circuit board 4 is connected to a button assembly 6 and a microphone 7. Each button on the button assembly 6 has Braille markings, allowing the user to select the button based on the Braille markings. The user inputs the desired floor to the main control circuit board 4 through the button assembly 6. The main control circuit board 4 is configured to repeat the input floor name once, allowing the blind user to confirm the correctness of the input. Once confirmed, the elevator operates normally. When the elevator approaches the desired floor, the main control circuit board 4 uses a floor positioning sensor to determine the current floor position. When the system determines that it is about to arrive, it uses the microphone 7 to announce the approach and exit of the elevator. Through the coordinated operation of these structures, the blind can travel flexibly and stably.
[0035] The floor positioning sensor connected to the main control circuit board 4 uses a sensor module. This module only requires power to function properly. The sensor module and the announcer are directly connected, allowing the main control circuit board 4 to receive external physical information to determine the current floor. The most noticeable change in air pressure during elevator ascent and descent is obvious and objective. The sensor module uses both a pressure sensor and a temperature sensor. The pressure sensor collects air pressure data and determines the current floor based on the pressure difference. Because of temperature variations, air pressure often changes uniformly; therefore, the main control circuit board 4 can use data from the temperature sensor... The pressure difference is adjusted to indicate whether a floor has risen or fallen by one floor. After adjusting the internal parameters, the main control circuit board 4 can use the pressure sensor to determine the current floor. Because these sensors collect objective physical data and only need to be powered on to work, they can operate normally in enclosed environments where satellite signals cannot be accessed, such as in elevators. This avoids reliance on traditional wireless signal positioning, improving the accuracy and reliability of positioning. Users can easily use the announcer when entering any elevator. The announcer has a simple structure and can be adapted to different buildings, effectively reducing the cost of elevator installation and use, and enabling blind people to travel more safely.
[0036] See also Figures 1 to 4 In one embodiment of this application, the protective shell 2 includes an upper shell 21 and a lower shell 22, and the button assembly 6 includes a mechanical button electrically connected to the main control circuit board 4 and an elastic button passing through the upper shell 21 and linked to the mechanical button.
[0037] The protective shell 2 is provided with a sound-emitting hole, and the microphone 7 is installed at the corresponding sound-emitting hole.
[0038] The announcer body 1 adopts a split structure, including an upper shell 21 and a lower shell 22. The upper shell 21 and the lower shell 22 can be detachably connected together to form a mounting cavity 11. The mounting cavity 11 can have a buffering effect to ensure that the shell and internal structure are not damaged. Furthermore, the split structure makes it easier to install the internal structure, which is beneficial to the installation and disassembly of the entire elevator controller and can effectively reduce maintenance costs.
[0039] The button assembly 6 and the sound-emitting hole are arranged opposite to each other, with one located on the upper housing 21 and the other on the lower housing 22. The button itself includes a flexible button that is easy for the user to operate and a mechanical button connected to the main control circuit board 4. This structure enables the user to accurately convey commands without hurting their hands. The above structure makes the operation and working parts of the broadcaster relatively arranged, avoiding mutual interference between components and effectively improving the stability of the equipment.
[0040] The broadcaster body 1 has a management switch on its side. The management switch is slidably connected to the housing and has anti-slip teeth. Users can use the management switch with anti-slip teeth to flexibly switch the elevator controller on and off, making the entire controller more convenient and flexible to use and avoiding energy waste.
[0041] See also Figures 1 to 4 In one embodiment of this application, the protective shell 2 is provided with a connecting structure 3. The connecting structure 3 includes a first connecting block 31 and a second connecting block 33 respectively connected to the upper shell 21 and the lower shell 22. The second connecting block 33 is provided with a reinforcing block 34 protruding toward the first connecting block 31. The first connecting block 31 is provided with a positioning locking groove 32 relative to the reinforcing block 34.
[0042] When the upper housing 21 and the lower housing 22 are assembled together, the reinforcing block 34 passes through the positioning and locking groove 32.
[0043] The connecting structure 3 is used to connect the broadcaster itself to a lanyard, making it more convenient for users to carry the broadcaster and preventing loss. In this application, a first connecting block 31 protrudes from one end of the upper housing 21, and a second connecting block 33 is correspondingly provided on the lower housing 22. When the upper and lower housings 22 are assembled together, the first connecting block 31 and the second connecting block 33 will also abut against each other to form a hook structure. In order to improve the strength of the structure, a reinforcing block 34 protrudes from the first connecting block 31 or the second connecting block 33, and a positioning locking groove 32 is correspondingly provided on the other connecting block. The reinforcing block 34 has the function of strengthening the hook structure and can cooperate with the positioning locking groove 32 to enable the upper and lower housings 22 to be quickly positioned and assembled, improving installation efficiency. Furthermore, the reinforcing rod passing through the positioning locking groove 32 can ensure the structural strength of the controller.
[0044] When the two connecting blocks are connected together, they will form a connecting cavity outside the housing. Blind people can more easily connect the hanging rope through the connecting cavity and use the external hanging rope with hooks to directly pass through the connecting cavity to quickly and flexibly connect the controller, making it more flexible and convenient for blind users.
[0045] See also Figure 2 In one embodiment of this application, the end of the protective shell 2 away from the connecting structure 3 is provided with a charging connection part 24 opposite to the battery. The charging connection part 24 passes through the protective shell 2 and is electrically connected to the battery.
[0046] The main control circuit board 4 is equipped with a battery, which is a rechargeable battery. In order to facilitate the use of the device, the broadcaster body 1 is provided with a charging connection part 24. The charging connection part 24 is located at the end away from the connection cavity, which makes it easy for the controller itself to be charged. This allows the broadcaster itself to work normally even when there is no power or network, which can effectively facilitate the travel of blind users.
[0047] See also Figures 2 to 4 In one embodiment of this application, a sealing structure 8 is provided between the outer periphery of the upper housing 21 and the outer periphery of the lower housing 22. The end face of the sealing structure 8 facing away from the connecting cavity is provided with a locking rod 81 and a locking part 82. The locking rod 81 and the locking part are respectively provided on the upper housing 21 and the lower housing 22.
[0048] When the upper housing 21 and the lower housing 22 are assembled together, the locking rod 81 passes through the locking part 82.
[0049] The mounting cavity 11 can accommodate different components, while the sealing structure 8 located between the upper and lower housings 22 consists of a sealing groove on the inner wall of the upper housing 21 and a sealing protrusion on the inner wall of the lower housing 22. When the sealing protrusion and the sealing groove are aligned, a sealing structure 8 is formed, preventing external dust from entering and affecting the connection between the upper and lower housings 22. Furthermore, the sealing structure 8 is equipped with a locking rod 81 and a locking part 82 corresponding to the first and second connecting blocks 33. In this application, the locking part 82 is an arc-shaped connecting structure 3 formed around the inner wall of the upper housing 21. The connecting structure 3 encloses a locking part 82. The sealing structure 8 on the lower housing 22 is provided with a relief groove corresponding to the connecting structure 3. The locking rod 81 is provided in the relief groove corresponding to the locking part 82. The locking rod 81 and the locking part 82 can form a reinforcing structure to further strengthen one side of the connecting cavity and ensure the stability of the connecting cavity. Furthermore, the locking rod 81, the locking part 82, the reinforcing block 34, and the positioning locking groove 32 cooperate with each other to enable the housing to be quickly positioned and spliced. Through the above structure, the structural strength can be guaranteed while making the entire controller easy to disassemble and assemble.
[0050] See also Figures 3 to 4 In one embodiment of this application, the main control circuit board 4 is provided with a plurality of through holes, the protective shell 2 is provided with an open guide connection part 25 facing the through holes, and the protective shell 2 is also provided with a mating connection part 26 that cooperates with the guide connection part 25. The guide connection part 25, the through holes, and the mating connection part 26 are fastened together by fasteners.
[0051] To secure the main control circuit board 4, multiple through holes are provided on it. In this application, the guide connection part 25 is a structure formed by the lower housing 22 recessed towards the through holes. The guide connection part 25 has an open end on the lower housing 22. The fasteners are generally bolts or screws. The screws can be used to move the lower housing 22 towards the through holes. The guide connection part 25 has a limiting part facing the through holes. The limiting part can limit the nut of the screw and prevent the screw from shaking. The upper housing 21 has a corresponding mating connection part 26. In order to ensure the connection strength, the mating connection part 26 has multiple reinforcing plates between it and the upper housing 21. The user can use a screw to pass through the guide connection part 25. After the screw passes through the through holes, it can be screwed into the mating connection part 26 with a tool. The nut is limited by the limiting part to prevent the screw from loosening. This structure can not only stably fix the circuit board, but also lock the upper and lower housings 22, ensuring the structural strength of the entire broadcaster body 1, ensuring the stability of the elevator controller, and making it safer for blind users.
[0052] See also Figures 2 to 4 In one embodiment of this application, the lower housing 22 is provided with a mounting groove 23 relative to the microphone 7. The mounting groove 23 surrounds the sound transmission hole. One end of the microphone 7 is connected to the main control circuit board 4, and the other end is connected to the mounting groove 23.
[0053] The circuit board is also connected to a microphone 7, which can be fixed by the mounting slot 23 provided in the lower housing 22. The lower housing 22 has a sound-emitting part in the mounting slot 23 and multiple sound-emitting holes are arrayed on the lower housing 22. The microphone 7 is connected to the circuit board and can repeatedly broadcast confirmation after the user selects a floor, which can prevent blind users from selecting the wrong floor. At the same time, when the user approaches or reaches the designated floor, the microphone will broadcast to the blind user so that the blind user can enter and exit the elevator in time and avoid missing the elevator.
[0054] Microphone 7 can also be configured with voice input function, allowing blind users to input floors by voice in addition to pressing buttons, which can make blind users travel more smoothly.
[0055] See also Figures 3 to 4 In one embodiment of this application, the protective shell 2 is provided with a display module 5, which is electrically connected to the main control circuit board 4.
[0056] The display module 5 includes a light-transmitting structure and a display unit. The light-transmitting structure is connected to the upper housing 21, and the display unit is connected to the main control circuit board 4 and is positioned facing the light-transmitting structure. The light-transmitting structure allows light from the display unit to pass through the housing, while also protecting the display unit from damage to the main control circuit board 4 and the display unit itself. The display unit allows the elevator controller to be used not only for blind users, but also to display time and floor information, thus enriching the controller's functionality.
