Description
A walkie-talkie with automatic fall warning Technical Field
[0001] This utility model belongs to the field of walkie-talkie technology, and in particular relates to a walkie-talkie with automatic fall warning. Background Technology
[0002] A walkie-talkie can make calls without any network support and without incurring call charges. It is suitable for relatively fixed and frequent calls. It consists of a casing, main unit, battery, belt clip, charging dock, and antenna.
[0003] While some existing walkie-talkies can provide automatic fall warnings, the impact of a fall can damage the internal automatic warning device, rendering it unusable and unable to sound. This prevents search personnel from locating the walkie-talkie by sound. Therefore, we propose a walkie-talkie with automatic fall warning functionality. Summary of the Invention
[0004] The purpose of this invention is to provide a walkie-talkie with automatic fall warning to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a walkie-talkie with automatic fall warning, including a walkie-talkie and an acceleration sensor, and further including:
[0006] A cavity is formed inside a walkie-talkie. An iron plate is fixedly installed inside the cavity. A through hole communicating with the cavity is provided on the walkie-talkie. A dustproof net is fixedly installed inside the through hole. A sliding block is slidably installed on the top of the cavity. A second damping rod is fixedly installed on the bottom of the sliding block. An installation block is provided below the second damping rod. A top plate fixed to one end of the second damping rod is slidably installed on the top of the installation block. A second spring is sleeved on the second damping rod.
[0007] The power chamber is located within the mounting block. An impact rod is slidably mounted within the mounting block. A fourth spring is fitted onto the impact rod. An elliptical plate is rotatably mounted within the power chamber and on one side of the impact rod. The acceleration sensor is fixedly mounted on one side of the mounting block.
[0008] A drive assembly, located on one side of the mounting block, is used to drive the elliptical plate to rotate;
[0009] A side plate is slidably installed in the cavity. A third damping rod is fixedly installed on one side of the side plate. A sliding plate that is slidably connected to the mounting block is fixedly installed at one end of the third damping rod. A third spring is sleeved on the third damping rod.
[0010] In this technical solution, when the walkie-talkie falls from a height, its descent speed will gradually increase under the influence of gravity. At this time, the acceleration sensor will detect the increased speed and activate the drive assembly. The drive assembly will cause the elliptical plate to rotate continuously, repeatedly pressing the impact rod. The fourth spring, under pressure, will repeatedly extend and retract, allowing the impact rod to repeatedly strike the iron plate. The impact on the iron plate will produce a sound. The dustproof net prevents external dust from entering the cavity. When the walkie-talkie falls to the ground, it will be impacted, causing the mounting block to shift vertically, horizontally, and backward. At this time, the second damping rod will contract under pressure, and the second spring will also contract under pressure. Then, the second damping rod and the second spring will extend. During the vertical displacement of the mounting block, the sliding plate will move up and down. The sliding block will cause the third damping rod to move up and down, which in turn will cause the side plate to slide up and down within the cavity. When the mounting block moves back and forth, the third damping rod and the third spring will be compressed and then extend, repeating this process to buffer the force generated by the back and forth movement of the mounting block. At this time, the mounting block will slide back and forth on the top plate. When the mounting block moves left and right, it will slide left and right on the sliding block, causing the top plate to move left and right. The top plate will then cause the second damping rod to move left and right, which in turn will cause the sliding block to move left and right. The left and right movement of the sliding block will cause the first damping rod and the first spring to repeatedly contract and extend, thus buffering the force of the left and right movement of the mounting block and ensuring all-round protection for the mounting block. This effectively reduces the severe vibration of the accelerometer and motor, preventing damage to them.
[0011] In the above technical solution, the driving component further includes:
[0012] The motor is fixedly mounted on one side of the mounting block. The output end of the motor passes through one side of the mounting block and is coaxially connected to the elliptical plate. A storage battery is fixedly mounted on the other side of the mounting block and is electrically connected to the motor.
[0013] In this technical solution, the battery is ensured to provide power to the motor. When the motor is started, the motor's output shaft will drive the elliptical plate to rotate.
[0014] In the above technical solution, the output shaft of the motor is further rotatably connected to the mounting block.
[0015] In this technical solution, the motor is ensured to operate normally.
[0016] In the above technical solution, the battery is further electrically connected to the acceleration sensor.
[0017] In this technical solution, it is ensured that the battery can provide power to the accelerometer.
[0018] In the above technical solution, furthermore, the two ends of the fourth spring are tightly welded to the impact rod and the inner wall of the power cavity, respectively.
[0019] In this technical solution, the structural stability of the fourth spring is ensured.
[0020] In the above technical solution, the two ends of the second spring are respectively tightly welded to the bottom of the sliding block and the top of the top plate, and the two ends of the third spring are respectively tightly welded to one side of the side plate and one side of the sliding plate.
[0021] In this technical solution, the structural stability of the second spring is ensured, and the structural stability of the third spring is guaranteed.
[0022] In the above technical solution, the elliptical plate further contacts one side of the impact rod.
[0023] In this technical solution, it is ensured that the elliptical plate can repeatedly push the impact rod when rotating.
[0024] The beneficial effects of this utility model are:
[0025] This walkie-talkie with automatic fall warning system effectively protects the acceleration sensor and motor by coordinating a dustproof net, through holes, cavities, mounting blocks, sliding blocks, a first damping rod, a first spring, a second damping rod, an iron plate, an acceleration sensor, a third damping rod, a third spring, a side plate, a battery, a second spring, a top plate, an impact rod, a power chamber, a fourth spring, an elliptical plate, a sliding plate, and a drive assembly. This prevents damage to the acceleration sensor and motor from impacts when the walkie-talkie falls from a height, ensuring that the acceleration sensor and motor continue to operate normally after the entire device has fallen to the ground.

[0037] Example 1:
[0038] Please refer to Figures 1-4. This embodiment provides a walkie-talkie with automatic fall warning, including a walkie-talkie 1 and an acceleration sensor 11, and also includes:
[0039] Cavity 4 is formed inside walkie-talkie 1. An iron plate 10 is fixedly installed inside cavity 4. A through hole 3 connected to cavity 4 is formed on walkie-talkie 1. A dustproof net 2 is fixedly installed inside through hole 3. A sliding block 6 is slidably installed on the top of cavity 4. A second damping rod 9 is fixedly installed on the bottom of sliding block 6. An installation block 5 is provided below the second damping rod 9. A top plate 18 fixed to one end of the second damping rod 9 is slidably installed on the top of installation block 5. A second spring 17 is sleeved on the second damping rod 9.
[0040] The power chamber 20 is located inside the mounting block 5. An impact rod 19 is slidably installed inside the mounting block 5. A fourth spring 21 is sleeved on the impact rod 19. An elliptical plate 22 is rotatably installed inside the power chamber 20 and on one side of the impact rod 19. An acceleration sensor 11 is fixedly installed on one side of the mounting block 5.
[0041] A drive assembly is located on one side of the mounting block 5 and is used to drive the elliptical plate 22 to rotate.
[0042] Side plate 15 is slidably installed in cavity 4. A third damping rod 13 is fixedly installed on one side of side plate 15. A slide plate 23 that is slidably connected to mounting block 5 is fixedly installed at one end of the third damping rod 13. A third spring 14 is sleeved on the third damping rod 13.
[0043] When walkie-talkie 1 falls from a height, its descent speed will gradually increase under the influence of gravity. At this time, acceleration sensor 11 will detect the increased speed and activate the drive assembly. The drive assembly will cause the elliptical plate 22 to rotate continuously, repeatedly pressing the impact rod 19. The fourth spring 21, under pressure, will repeatedly extend and retract, allowing the impact rod 19 to repeatedly strike the iron plate 10. The impact on the iron plate 10 will produce a sound. The dustproof net 2 prevents external dust from entering the cavity 4. After walkie-talkie 1 falls to the ground, it will be impacted, causing the mounting block 5 to move up, down, left, right, and back and forth. At this time, the second damping rod 9 will contract under pressure, and the second spring 17 will also contract under pressure. Then, the second damping rod 9 and the second spring 17 will extend. During the up-and-down movement of the mounting block 5, the sliding plate 23 will move up and down. This will cause the third damping rod 13 to move up and down, and the third damping rod 13 will cause the side plate 15 to slide up and down in the cavity 4. When the mounting block 5 moves back and forth, the third damping rod 13 and the third spring 14 will be compressed and contract, and then extend again. This will repeat repeatedly to buffer the force generated by the back and forth movement of the mounting block 5. At this time, the mounting block 5 will slide back and forth on the top plate 18. When the mounting block 5 moves left and right, the mounting block 5 will slide left and right on the slide plate 23. The mounting block 5 will cause the top plate 18 to move left and right, and the top plate 18 will cause the second damping rod 9 to move left and right. The second damping rod 9 will cause the sliding block 6 to move left and right. The left and right movement of the sliding block 6 will cause the first damping rod 7 and the first spring 8 to repeatedly contract and extend, thereby buffering the force of the left and right movement of the mounting block 5 and ensuring that the mounting block 5 can be protected in all directions. This will effectively reduce the violent vibration of the acceleration sensor 11 and the motor 12 and prevent damage to the acceleration sensor 11 and the motor 12.

[0046] Motor 12 is fixedly installed on one side of mounting block 5. The output end of motor 12 passes through one side of mounting block 5 and is coaxially connected to elliptical plate 22. Battery 16 is fixedly installed on the other side of mounting block 5 and is electrically connected to motor 12.
[0047] In this process, the battery 16 is ensured to provide power to the motor 12. When the motor 12 is started, its output shaft will drive the elliptical plate 22 to rotate.
[0048] Example 3:
[0049] This embodiment provides a walkie-talkie with automatic fall warning. In addition to the technical solutions of the above embodiments, it also has the following technical features: the output shaft of motor 12 is rotatably connected to the mounting block 5.
[0050] This includes ensuring that motor 12 can operate normally.
[0051] Example 4:
[0052] This embodiment provides a walkie-talkie with automatic fall warning. In addition to the technical solutions of the above embodiments, it also has the following technical features: the battery 16 is electrically connected to the acceleration sensor 11.
[0053] This ensures that the battery 16 can provide power to the accelerometer 11.
[0054] Example 5:
[0055] This embodiment provides a walkie-talkie with automatic fall warning. In addition to the technical solution of the above embodiment, it also has the following technical features: the two ends of the fourth spring 21 are tightly welded to the impact rod 19 and the inner wall of the power cavity 20, respectively.
[0056] Among these measures, the structural stability of the fourth spring 21 is ensured.
[0057] Example 6:
[0058] This embodiment provides a walkie-talkie with automatic fall warning. In addition to the technical solution of the above embodiment, it also has the following technical features: the two ends of the second spring 17 are tightly welded to the bottom of the sliding block 6 and the top of the top plate 18, respectively; and the two ends of the third spring 14 are tightly welded to one side of the side plate 15 and one side of the slide plate 23, respectively.
[0059] Specifically, this ensures the structural stability of the second spring 17 and guarantees the structural stability of the third spring 14.
[0060] Example 7:
[0061] This embodiment provides a walkie-talkie with automatic fall warning. In addition to the technical solution of the above embodiment, it also has the following technical features: the elliptical plate 22 is in contact with one side of the impact rod 19.
[0062] This ensures that the elliptical plate 22 can repeatedly push the impact rod 19 when rotating.
[0063] Working principle: When walkie-talkie 1 falls from a height, its descent speed will gradually increase under the influence of gravity. At this time, the acceleration sensor 11 will detect the increased speed and start the motor 12. Subsequently, the output shaft of the motor 12 will drive the elliptical plate 22 to rotate continuously. The elliptical plate 22 will repeatedly compress the impact rod 19, and the fourth spring 21 will repeatedly extend and retract under compression, allowing the impact rod 19 to repeatedly strike the iron plate 10. At this time, the iron plate 10 will make a sound upon impact. After walkie-talkie 1 falls to the ground, it will be impacted, and the mounting block 5 will move up, down, left, right, and back and forth. At this time, the second damping rod 9 will be compressed and contracted, and the second spring 17 will also be compressed and contracted. Then, the second damping rod 9 and the second spring 17 will extend. During the up and down displacement of the mounting block 5, the sliding plate 23 will move up and down, and the sliding plate 23 will drive the third damping rod 13 up and down. Displacement causes the third damping rod 13 to drive the side plate 15 to slide up and down within the cavity 4. When the mounting block 5 moves back and forth, the third damping rod 13 and the third spring 14 are compressed and will contract, and then extend, repeating this process to buffer the force generated by the back and forth displacement of the mounting block 5. At this time, the mounting block 5 will slide back and forth on the top plate 18. When the mounting block 5 moves left and right, it will slide left and right on the slide plate 23. The mounting block 5 will drive the top plate 18 to move left and right, which in turn will drive the second damping rod 9 to move left and right. The second damping rod 9 will drive the sliding block 6 to move left and right. The left and right displacement of the sliding block 6 will cause the first damping rod 7 and the first spring 8 to repeatedly contract and extend, thereby buffering the force of the left and right displacement of the mounting block 5 and ensuring all-round protection for the mounting block 5. This will effectively reduce the severe vibration of the acceleration sensor 11 and the motor 12 and prevent damage to the acceleration sensor 11 and the motor 12.

Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
