Description

Technical Field

[0001] This utility model relates to the field of smart home equipment technology, and in particular to an emergency call device. Background Technology

[0002] The personal safety of middle-aged and elderly people living alone or in bed has always been a major concern.

[0003] Some children or contacts choose to equip their elderly parents with smartphones, smartwatches, and other communication devices to keep track of their whereabouts. However, many elderly people have poor learning and adaptability to these devices and often struggle to make or receive calls for various reasons, resulting in inefficient communication. This problem becomes even more pronounced in emergencies, where the inability to quickly contact the outside world can delay rescue efforts and potentially cause irreparable damage.

[0004] Currently, there are some alarm call devices on the market specifically designed for middle-aged and elderly people living alone or bedridden. However, these alarm devices use a single button alarm and place multiple function buttons on the panel, which still poses difficulties for middle-aged and elderly people whose cognitive and physical abilities are aging. Furthermore, there is a risk of accidental activation leading to false alarms or failure to alarm, whether in daily use or in emergency situations.

[0005] In summary, there is an urgent need for an alarm call device for middle-aged and elderly people that is easy to operate and understand, can be quickly triggered in emergencies, and can avoid accidental activation in daily life. Utility Model Content

Detailed Implementation

[0053] The specific implementation of the present invention will now be described with reference to the accompanying drawings.

[0054] Example 1

[0055] This embodiment provides an emergency call device, such as Figures 1-3 As shown, where Figure 1 Axonometric drawing of the external structure. Figure 2 Here is a schematic diagram of its internal structure. Figure 3 A partial circuit connection block diagram is provided; it includes:

[0056] The outer casing 1 has an operating hole on its side;

[0057] The manual alarm assembly includes an operating rope 2, a trigger block 3, a trigger switch 4, and a reset component 5.

[0058] One end of the operating rope 2 is exposed outside the outer shell 1, and the other end extends into the inner shell 1 through the operating hole and is connected to the trigger block 3; the trigger block 3 is configured to move along a preset linear preset path, the end of the preset path is close to the operating hole, and a trigger position is set on the preset path, the trigger position is close to the operating hole and far away from the starting point of the preset path.

[0059] The trigger switch 4 is located inside the housing 1 and in the trigger position. The trigger position is located on a preset path. It is configured such that when the trigger block 3 moves to the trigger position, the trigger part of the trigger switch 4 is connected to the trigger block 3.

[0060] The reset component 5 is configured to keep the trigger block 3 normally at the starting point of the preset path, with the starting point far away from the trigger position;

[0061] The functional module group, which is located inside the outer casing 1, includes a voice recognition module 14, a GPS positioning module 15, an alarm module 16, and a communication module 17; wherein, the voice recognition module 14 includes an alarm voice receiving module 1401 and an alarm voice information processing module 1402.

[0062] The main control module 20 is electrically connected to the trigger switch 4, the functional module group, the monitoring platform server 23, and / or the control terminal 24.

[0063] For details on how to configure the manual alarm component in this embodiment, please refer to [link / reference needed]. Figure 1 As shown:

[0064] The outer casing 1 of the device in this embodiment is provided with a sliding groove 7. The sliding groove 7 is arranged along a preset path. The trigger block 3 is slidably arranged in the sliding groove 7. The trigger switch 4 is arranged at the bottom wall of the sliding groove 7 and is located at the trigger position. The sliding groove 7 plays a guiding and limiting role for the trigger block 3.

[0065] In this embodiment, a spring installed in the slide groove 7 is used as the reset element 5. One end of the spring is installed on the inner wall at the end of the slide groove 7, and the other end is installed on the trigger block 3. When the spring is in its original state, the trigger block 3 is located at the original position, i.e., the starting point of the preset path. When the trigger block 3 moves from the starting point to the ending point of the preset path, the spring is in a stretched state, continuously applying a reverse pulling force to the trigger block 3. This can effectively avoid the problem of accidental touch of the operating rope 2 causing slider displacement and thus erroneous alarm triggering in daily life.

[0066] This embodiment uses a combination of voice distress call and manual rope alarm. Voice distress call only requires a short command, and manual alarm only requires pulling the operation rope 2 once, which greatly simplifies the operation logic and reduces the difficulty of operation. It can be quickly mastered by middle-aged and elderly people. In an emergency, they can quickly trigger the alarm by habitual operation, and in daily life, they can avoid accidental activation as much as possible.

[0067] In this embodiment, the voice recognition module 14 includes an alarm voice receiving module 1401 and an alarm voice information processing module 1402. The alarm voice receiving module 1401 is used to receive alarm commands issued by the user, such as "help," "alarm," "call for help," "help me," "save me," etc. In this embodiment, a microphone hole 1012 is provided on the front of the outer casing 1. Figure 1As shown, the alarm voice receiving module 1401 is located inside the outer casing 1 at a position corresponding to the sound receiving hole 1012; the alarm voice information processing module 1402 is used to identify whether the alarm password received by the alarm voice receiving module 1401 is consistent with its set alarm password. If they are consistent, the main control module 20 is controlled to drive the alarm module 16, and the alarm module 16 sends out an alarm through the communication module 17. Considering that the memory of middle-aged and elderly people gradually declines and they are prone to panic in emergencies, the alarm passwords set by the alarm voice information processing module 1402 in the voice recognition module 14 of this embodiment cover a variety of commonly used alarm and distress calls in daily life. They are all short and easy to pronounce, making it convenient to quickly trigger the alarm by voice in emergencies, such as "help", "alarm", "call for help", "help me", "save me", etc. In practical applications, the setting and content range of the alarm password can be pre-stored by the manufacturer before leaving the factory, or it can be customized by the external control terminal 24 during later use.

[0068] The GPS positioning module 15 is configured to generate real-time positioning data for the device. Specifically, in this embodiment, considering that the devices carried by middle-aged and elderly people need to ensure a long battery life, the GPS positioning module 15 does not work continuously. It is usually in standby mode and is activated when needed to immediately obtain and send real-time positioning data. After the activation mode is activated for a certain period of time, if there is no need to work, it will return to standby mode, thereby achieving timely response and saving power consumption.

[0069] The communication module 17 is configured to establish a communication connection between this device and the designated monitoring platform server 23 and / or control terminal 24. Considering factors such as manufacturing costs, equipment structure, and reliability, this embodiment specifically uses the Internet of Things communication module 17 to communicate with the remote designated monitoring platform server 23 and / or control terminal 24. In this embodiment, the control terminal 24 is specifically a mobile phone with a matching APP installed. Whether it is the owner of this device or the owner's contact person, such as a child, they can connect to the communication module 17 of this device through the mobile phone and remotely view the device status (such as online, offline, real-time location, etc.) and receive alarm information in the control panel of the matching mobile APP. It should be noted that, in this embodiment, there are many mature solutions disclosed in the art for the specific configuration of the communication module 17, the settings of the matching mobile APP, and the specific model and configuration of the speaker unit. Under the guidance of this application, those skilled in the art can flexibly choose according to their needs when applying the technical solution of this application. Therefore, it will not be elaborated further here.

[0070] When the user speaks the alarm command or pulls the operating rope 2 to open the trigger switch 4, the main control module 20 sends the alarm signal corresponding to the unique device ID set by the alarm module 16 and the real-time device location data provided by the GPS positioning module 15 to the designated monitoring platform server 23 and / or control terminal 24 through the communication module 17. At the same time, the main control module 20 also periodically sends the real-time device location data to the designated monitoring platform server 23 and / or control terminal 24 so that the contact person can keep track of the real-time location of the device holder at any time.

[0071] More specifically, as mentioned above, in this embodiment, a mobile phone with an accompanying APP is used as the designated control terminal 24. The mobile phone is connected to the communication module 17 in this device to transmit data. In this embodiment, when an alarm signal is sent to the mobile phone with the accompanying APP, the accompanying APP extracts relevant information and generates a text pop-up window and an alarm notification containing key alarm information such as the alarm time and alarm location. The text pop-up window is forcibly pushed to the mobile phone screen, and the alarm notification is forcibly played through the mobile phone speaker to prevent the contact from missing urgent and critical information. It should be noted that there are currently many mature solutions available for configuring the monitoring platform server 23 and the accompanying APP. Under the guidance of this application, those skilled in the art can flexibly choose according to their needs when making practical applications, so further details are not provided here.

[0072] In a preferred embodiment, an emergency alarm button 18 electrically connected to the main control module 20 is also provided. This button is located on the surface of the housing 1, and more specifically, on a surface such as... Figure 1 The front center area of ​​the outer casing 1 is shown; at least a portion of the surface of the emergency alarm button 18 is recessed into the outer casing 1, and an alarm button indicator ring 1801 is provided around the outer side of the emergency alarm button 18; in this preferred embodiment, the emergency alarm button 18 will directly trigger the alarm function when pressed, and the main control module 20 will drive the alarm button to perform the alarm operation.

[0073] In this preferred design, a separate emergency alarm button 18 is added, forming a coordinated alarm mode of physical button, voice call for help, and manual triggering. Even if some alarm functions fail unexpectedly in an emergency, there is a reliable backup option, further enhancing safety redundancy. The emergency alarm button 18 is located separately on the front of the outer casing 1 without any other unnecessary buttons, making it simple to operate and very user-friendly for middle-aged and elderly people. The inward-curving emergency alarm button 18 is mainly to prevent accidental activation due to bumps and knocks, while also locking the fingertip for quick pressing and triggering. The concave shape also shortens the trigger distance, resulting in a more sensitive response. An alarm button indicator ring 1801 is set around the emergency alarm button 18, making it more conspicuous and easier for middle-aged and elderly people to use in dimly lit environments.

[0074] In a preferred embodiment, the functional module group further includes a voice feedback module 19, which is electrically connected to the main control module 20. The voice feedback module 19 includes a voice information feedback module 1901 and a speaker module 1902. The module is configured to provide feedback on status voice, which includes at least one of alarm in progress, alarm successful, and alarm failed.

[0075] Specifically, such as Figure 3 As shown, in this preferred embodiment, the voice feedback module 1901 is electrically connected to the main control module 20, and the speaker module 1902 is electrically connected to the voice feedback module 1901; additionally, as shown... Figure 1 As shown, in this preferred embodiment, a speaker hole 1011 is pre-installed on the front of the outer casing 1, and the speaker module 1902 is located inside the outer casing 1 at the position corresponding to the speaker hole 1011. When the main control module 20 drives the alarm module 16 to perform an alarm operation, it will generate different electrical signals representing different states in real time according to the alarm progress of the alarm module 16, such as alarm in progress, alarm successful, alarm failed, etc., and transmit the electrical signals representing the real-time status to the voice information feedback module 1901 in real time. After receiving the electrical signals, the voice information feedback module 1901 drives the speaker module 1902 to broadcast the real-time status represented by the real-time electrical signals in the form of voice announcements.

[0076] This preferred solution provides real-time voice broadcast feedback on the alarm status, allowing alarm users to keep track of the alarm's progress in real time.

[0077] In a preferred embodiment, a reset button 21 is also provided, which is electrically connected to the main control module 20. This reset button is recessed within the outer casing 1. Figure 1 As shown.

[0078] The reset button 21 in this preferred embodiment allows users to force a restart and reset of the device in case of unexpected malfunctions or crashes, enabling self-troubleshooting. The reset button 21 is recessed within the outer casing 1 to prevent accidental activation during daily use that could lead to an incorrect device restart.

[0079] In a preferred embodiment of this invention, a status indicator breathing light 22 is also provided, such as... Figure 1 As shown. The status indicator breathing light 22 is electrically connected to the main control module 20, and uses different light colors to indicate different device statuses, including at least one of power on, power off, standby, connected to the network, and not connected to the network.

[0080] Specifically, in this preferred embodiment, depending on the type of LED used, the breathing color of the status indicator breathing light 22 can be the same color, such as green flashing in the power-on state, blue flashing in the power-off state, yellow flashing in the standby state, and red flashing in the offline state. It can also be a combination of two or more colors, such as blue and green flashing alternately in the power-on state, and yellow and red flashing alternately in the power-off state.

[0081] Example 2

[0082] This embodiment provides an emergency call device, whose structure is basically the same as that of Embodiment 1, except that:

[0083] The outer casing 1 includes an upper casing 101 and a lower casing 102 that are arranged opposite to each other and connected to each other, and a mounting groove is provided between the upper casing 101 and the lower casing 102;

[0084] Also includes installation disk 6, such as Figures 4-5 As shown, where Figure 4 This is a schematic diagram of the internal mounting plate 6A, where surface A specifically refers to the surface where the sliding groove 7 is located. Figure 5 The diagram shows a cross-sectional view of the internal structure of the mounting plate 6A perpendicular to its surface. The mounting plate 6 is disposed in the mounting groove and includes a circular mounting plate and a sidewall disposed along the circumference of the mounting plate at the edge of the mounting plate. The mounting plate is rotatably connected to the upper housing 101 and / or the lower housing 102, and an operation hole is disposed on the sidewall. In this embodiment, the upper housing 101 and the lower housing 102 are fixedly connected by a mounting post 103 perpendicular to the front of the upper housing 101. The center of the mounting plate 6 is rotatably connected to the mounting post 103 by a bearing, thereby realizing the rotatable connection with the upper housing 101 and the lower housing 102.

[0085] The mounting plate of the mounting disk 6 is provided with a slide groove 7 along a preset path, and the slide groove 7 is provided with a trigger opening 8 at the inner bottom wall of the trigger position;

[0086] The trigger block 3 is slidably disposed in the slide groove 7. A first spring pin 9 is provided on the side of the trigger block 3 facing the mounting plate. The head end of the first spring pin 9 abuts against the inner bottom wall of the slide groove 7 and can extend out of the slide groove 7 from the trigger opening 8.

[0087] It also includes a spring 10, which is ring-shaped and concentrically disposed inside the housing 1 with the mounting plate. Its inner radius is smaller than the distance between the center of the mounting plate and the trigger position, and its outer radius is larger than the distance between the center of the mounting plate and the trigger position. The head end of the first spring pin 9 can abut against the spring 10 at the trigger position.

[0088] The trigger switch 4 and the first spring pin 9 are respectively disposed on both sides of the spring 10. There are multiple trigger switches 4, which are distributed along the circumference of the spring 10. All trigger switches 4 are configured such that when the head end of the first spring pin 9 abuts against the spring 10, the trigger part of at least one trigger switch 4 is connected to the spring 10.

[0089] This embodiment, by setting up a mounting plate 6, allows the trigger block 3 and the operating rope 2 in the manual alarm component to rotate. Specifically, if the operating rope 2 is set in a single fixed position, it may be difficult to operate when pulling the operating rope 2 from an angle deviating from its length direction. The limb control and strength of middle-aged and elderly people are already somewhat deteriorated, and pulling the operating rope 2 from an inclined direction makes it impossible to concentrate force. Furthermore, long-term inclined pulling of the operating rope 2 will cause concentrated wear on the inclined side, affecting its service life. However, this embodiment, by setting up a rotating mounting plate 6, ensures that when the user pulls the operating rope 2, the rotating plate rotates to the corresponding position. In a direction parallel to the radial direction of the rotating plate, regardless of the angle from which the operating rope 2 is pulled, the operating plate will immediately rotate until the operating rope 2 aligns with its radial direction, facilitating concentrated force and preventing abnormal wear of the operating rope 2. This embodiment is applicable to a wide range of scenarios, especially suitable for elderly people who are bedridden and for whom this device is installed on one side of the bed.

[0090] This embodiment uses a ring-shaped spring 10 in conjunction with multiple trigger switches 4 arranged in an array below the spring 10. This is adapted to a trigger block 3 that rotates while sliding. When the trigger block 3 rotates to any angle and moves to the trigger position, the first spring pin 9 on it extends from the trigger opening 8 and presses against the spring 10. The spring 10, under pressure, undergoes elastic deformation and bends downwards, contacting the nearby trigger switch 4 to achieve triggering. Thus, this embodiment achieves the technical effect of quickly achieving manual triggering when the mounting plate 6 rotates to any angle. The width of the spring 10 satisfies the condition that its inner radius is smaller than the distance between the center of the mounting plate and the trigger position, and its outer radius is larger than the distance between the center of the mounting plate and the trigger position, allowing it to effectively cover the area where the trigger switch 4 and the trigger opening 8 are located, ensuring a high success rate and accuracy of triggering.

[0091] In this embodiment, a combination of a wheel 501 and a coil spring 502 serves as the reset element 5, replacing the spring in embodiment 1. Specifically, to coordinate the installation and fixing positions between the mounting plate 6, the slide groove 7, and the outer casing 1, while keeping the volume and internal space of the outer casing 1 essentially unchanged, the stroke of the slide groove 7 in this embodiment is shortened compared to embodiment 1. Figure 4As shown; in this case, the coil spring 502 is more flexible in its use of space than the spring. When it is coiled around the wheel 501, it occupies less space in the groove 7. Thus, while shortening the length of the groove 7, the length of the preset path is guaranteed, and the trip of the trigger block 3 in the preset path is not too short, which would lead to an increase in the false trigger rate. In addition, the combination of the coil spring 502 and the wheel 501 is also more convenient to rotate synchronously with the mounting plate 6.

[0092] Example 3

[0093] This embodiment provides an emergency call device, such as Figure 6 As shown, its structure is basically the same as that of Example 2, except that:

[0094] It also includes a limiting component, which is disposed inside the outer casing 1, and includes a limiting wheel 11 and a limiting ring 12;

[0095] The limiting wheel 11 and the limiting ring 12 are both concentrically set with the mounting plate 6. The limiting wheel 11 is installed on the mounting plate of the mounting plate 6, more specifically on the B side of the mounting plate, that is, the side opposite to the slide groove 7, and rotates synchronously with the mounting plate 6. The limiting ring 12 is fixedly set on the outside of the limiting wheel 11, more specifically, it is fixedly connected to the lower housing 102.

[0096] A second spring pin 13 is provided at the edge of the limiting wheel 11. The head end of the second spring pin 13 abuts against the inner side of the limiting ring 12. The head end of the second spring pin 13 forms a converging slope. The converging slope is specifically a smooth curved surface such as a cone, sphere, or frustum. In this embodiment, it is more specifically a sphere. Figure 6 As shown;

[0097] Multiple limiting grooves are arranged circumferentially on the inner side of the limiting ring 12. The shape of the limiting grooves is adapted to the shape of the head end of the second spring pin 13, and the head end of the second spring pin 13 can abut against the limiting groove; for example Figure 6 As shown, in this embodiment, the head end of the second spring pin 13 is formed as a spherical surface, and the shape of the limiting groove is the corresponding concave spherical surface.

[0098] This embodiment adds a limiting component to the existing embodiment 2. When the mounting plate 6 rotates, the second spring pin 13, which rotates along with it, will segmentally connect with the limiting groove on the inner side of the limiting ring 12, thereby changing the rotation mode of the mounting plate 6 from free rotation to segmented rotation-stop mode. This setting can further improve the stability of the mounting plate 6 after it rotates to a suitable trigger angle. Specifically, after the mounting plate 6 rotates to a suitable position, the head end of the second spring pin 13 abuts into the limiting groove set at the corresponding position on the limiting ring 12, forming a tenon-and-mortise connection. The mounting plate 6 thus stops rotating and remains stationary, which makes it easier for the user to concentrate force when pulling the operating rope 2, and the force feedback and rotation feedback are clearer.
