Abstract
Description
Technical Field
[0001] The invention relates to the technical field of waterproof intercoms, and in particular to a waterproof and floatable intercom. Background Art
[0002] As a convenient wireless communication device, walkie-talkies are widely used in marine transportation, fishing operations, water rescue, and water sports. With the diversification of application environments, the protection performance of walkie-talkies, especially waterproof performance, has been continuously improved. Currently, many walkie-talkie products have a certain degree of waterproofing, which can resist water intrusion for a short period of time, ensuring that the device can continue to function normally for a short period of time after accidentally falling into the water.
[0003] However, the existing technology still has many shortcomings. First, in actual applications, walkie-talkies often accidentally fall into water, and due to the great depth of water bodies such as oceans and lakes, walkie-talkies that fall into the water tend to sink quickly to the bottom. Although the equipment is waterproof, being in an underwater high-pressure environment for a long time may still cause the sealing performance to fail, resulting in water damage to the internal circuit. In addition, even if the walkie-talkie itself is not immediately damaged, after sinking into deep water, the lack of buoys or positioning measures will make it difficult to salvage it, increasing the risk of equipment loss and operation interruption. Especially in bad weather or when operating at night, salvage is almost impossible.
[0004] To this end, we propose a waterproof and floatable walkie-talkie. Summary of the Invention

[0030] As the connecting hook is disengaged from the connecting hole, the extension rod loses its original locking constraint, allowing the connecting shaft to be released from the restriction and resume a free moving state.
[0031] Through the above design, the unlocking action can be achieved reliably and quickly within the first time after the walkie-talkie falls into the water, providing a prerequisite guarantee for the subsequent deployment of the airbag assembly and the floating of the walkie-talkie.

DETAILED DESCRIPTION
[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0044] Example 1: Please refer to Figure 1-10 The present invention provides a technical solution: a waterproof and floatable intercom, comprising:
[0045] Housing 10;
[0046] The airbag assembly 20 is disposed in the housing 10 and includes:
[0047] Storage plates 21, two of which are symmetrically arranged about the vertical center plane of the intercom. A connecting shaft 22 is fixedly connected to one side of the storage plate 21. An air passage is defined within the connecting shaft 22. An airbag 1 23 is provided within the storage plate 21. The airbag 1 23 is partially adhered to the inner wall of the storage plate 21. A rubber seal 24 is secured to the storage plate 21.
[0048] A gas generating assembly 30 is provided on the lower side of the housing 10 and is used to inflate the airbag 1 23 in the airbag assembly 20 when a water fall is detected;
[0049] A state adjustment component 40 is provided at the upper and lower ends of the housing 10 and is used to adjust the intercom to a vertical posture underwater;
[0050] It should be noted that when the walkie-talkie accidentally falls into the water, the gas generating assembly 30 can promptly detect the walkie-talkie's submerged state. First, the gas generating assembly 30 preferentially cooperates with the state adjustment assembly 40, driving the state adjustment assembly 40 to quickly adjust the walkie-talkie's posture in the water, so that the walkie-talkie is in a vertical position with the speaker facing upward. This adjustment operation ensures that the speaker is always in a position that is conducive to sound transmission during subsequent floating.
[0051] Then, the gas generating assembly 30 activates its inflation function, injecting the generated gas into airbag 1 23, causing it to gradually expand. During this process, the storage plate 21, driven by the connecting shaft 22, rotates from its original position parallel to the longitudinal centerline of the intercom to a position substantially perpendicular to the intercom body.
[0052] When the airbag 1 23 in the storage plate 21 is fully inflated, the airbag 1 23 uses the buoyancy generated by itself to push the walkie-talkie as a whole to the surface of the water, and preferentially allows the speaker end to break through the water surface, thereby ensuring that the walkie-talkie can smoothly send out sound signals even in a floating state.
[0053] It is worth noting that by prioritizing the vertical posture of the walkie-talkie as soon as possible after it falls into the water, the stability and sound propagation effect of the walkie-talkie when floating on the water can be significantly improved, which helps users or rescuers hear sound signals at a longer distance, thereby locating the fallen walkie-talkie more quickly and accurately.
[0054] Further as Figure 2 As shown, it is worth noting that the airbag assembly 20 further includes:
[0055] The slider 25 is slidably connected to the housing 10. The connecting shaft 22 is rotatably connected to the slider 25. A connecting ear 26 is fixedly connected to the connecting shaft 22. A 90-degree annular groove 27 is formed on the slider 25. The connecting ear 26 can slide in the groove 27.
[0056] A vortex spring 28 is disposed between the connecting shaft 22 and the slider 25 , with one end fixedly connected to the inner wall of the slider 25 and the other end fixedly connected to the outer wall of the connecting shaft 22 , for providing elastic restoring force for the connecting shaft 22 ;
[0057] Abutment piece 29, said abutment piece 29 is fixedly connected to the housing 10, and a spring 291 is provided between said abutment piece 29 and the slider 25;
[0058] An unlocking mechanism 50 , the unlocking mechanism 50 is used to release or lock the connecting shaft 22 ;
[0059] It should be noted that, first, the unlocking mechanism 50 releases the locking state of the connecting shaft 22. At this point, the elastic potential energy of the spring 1 291 is released and converted into kinetic energy, pushing the slider 25 to slide along the interior of the housing 10. As the slider 25 moves, it also moves the connecting shaft 22 and the storage plate 21 to which it is fixed.
[0060] When the storage plate 21 is completely removed from the housing 10, it is no longer constrained by the housing 10 and is free. At this point, the spiral spring 28 further releases its elastic potential energy, converting it into kinetic energy, driving the connecting shaft 22 to rotate. Because the connecting lug 26 on the connecting shaft 22 is constrained by the 90-degree groove 27, the connecting shaft 22 can only complete a 90-degree rotation, thus placing the storage plate 21 in a substantially perpendicular position relative to the intercom body.
[0061] It is worth noting that with the above-mentioned storage structure, during daily use of the walkie-talkie, the storage plate 21 is in a state of being vertically stored inside the shell 10, which does not affect the normal use and operation of the walkie-talkie and can be quickly unfolded in water.
[0062] Further as Figure 9 and Figure 10 As shown, it is worth noting that the unlocking mechanism 50 includes:
[0063] An extension rod 51, the extension rod 51 is fixedly connected to the connecting shaft 22, a connecting hole is formed at the end of the connecting shaft 22, and a channel 52 is formed in the middle of the housing 10;
[0064] An unlocking valve 53 is provided in the channel 52 . A rubber ring 54 is sleeved on the outer side of the unlocking valve 53 . The unlocking valve 53 is interference-connected to the channel 52 via the rubber ring 54 .
[0065] A connecting hook 55 , which is fixedly connected to the top of the unlocking valve 53 and is used to be inserted into the connecting hole of the extension rod 51 to lock the connecting shaft 22 ;
[0066] It should be noted that when the intercom falls into water, the gas generating assembly 30 promptly detects the water drop and initiates a reaction, generating gas that enters the unlocking mechanism 50 through the channel 52. As the amount of gas increases, the gas gradually generates a certain thrust in the channel 52, eventually pushing the unlocking valve 53 out along the axial direction of the channel 52.
[0067] After the unlocking valve 53 is pushed out to the disengagement channel 52 by the gas thrust, the connecting hook 55 originally fixedly connected to the top of the unlocking valve 53 also disengages from the connecting hole opened at the end of the extension rod 51, thereby realizing the separation between the unlocking valve 53 and the extension rod 51.
[0068] As the connecting hook 55 is disengaged from the connecting hole, the extension rod 51 loses its original locking constraint, so that the connecting shaft 22 is released from the constraint and resumes a free movable state.
[0069] Through the above design, the unlocking action can be realized reliably and quickly within the first time after the walkie-talkie falls into the water, which provides a prerequisite for the subsequent deployment of the airbag assembly 20 and the floating of the walkie-talkie.
[0070] Further as Figure 8 As shown, it is worth noting that the gas generating assembly 30 includes:
[0071] A reaction box 31 is fixedly connected to the housing 10. The top of the reaction box 31 is connected to the channel 52. A water channel hole 32 is opened on one side of the bottom of the reaction box 31. An abutting valve 33 is provided at the water channel hole 32. A vertical plate is fixedly connected to the reaction box 31 at the abutting valve 33. A second spring 34 is provided between the vertical plate and the abutting valve 33. One end of the second spring 34 is fixedly connected to the abutting valve 33, and the other end is fixedly connected to the vertical plate.
[0072] A water-soluble plate 35 is provided in the reaction box 31. The water-soluble plate 35 divides the reaction box 31 into a reaction chamber and a water storage chamber, respectively. The reaction chamber is filled with a material that generates gas when in contact with water. The reaction chamber is filled with sodium bicarbonate and citric acid.
[0073] It should be noted that when the intercom falls into water and reaches a predetermined depth, the water pressure forces the abutment valve 33 at the bottom of the reaction box 31 to open, allowing water from outside to rapidly flow into the water storage chamber at the bottom of the reaction box 31 through the water channel hole 32. When the water pressure inside and outside the water storage chamber reaches equilibrium, the elastic restoring force of the second spring 34 causes the abutment valve 33 to return to its original position, thereby restoring the seal of the reaction box 31 and preventing gas leakage from this point during the gas generation process.
[0074] With the water into, water-soluble plate 35 is gradually dissolved, water-soluble plate 35 can be made of gelatin, after water-soluble plate 35 completely dissolved, the water in the water storage warehouse is in full contact with the sodium bicarbonate and citric acid in the reaction warehouse, the following chemical reaction occurs:
[0075] 3NaHCO3+C6H8O7=C6H5O7Na3+3H2O+3CO2↑
[0076] Through the above reaction, a large amount of carbon dioxide gas is released, the gas enters the inside of the gas bag assembly 20 along the channel 52, inflates the gas bag quickly, and then relies on the buoyancy of the gas bag to lift the interphone as a whole to the water surface.
[0077] Notably, the design of opening the abutment valve 33 by water pressure can effectively avoid the accidental triggering of gas release in shallow water areas such as water holes and shoals, thereby reducing resource waste and ensuring the reusability of the equipment. In addition, by setting the water-soluble plate 35 as a physical delay barrier, not only can it ensure that the water is fully penetrated and distributed before the reaction occurs, but also can make the gas release process more stable and orderly.
[0078] At the same time, sodium bicarbonate and citric acid are selected as the reaction material, which not only produces less reaction heat, avoiding the influence of high temperature on the equipment and internal electronic components, but also releases non-toxic and harmless carbon dioxide gas, which has good safety. The water generated by the reaction can also continue to accelerate the dissolution process of the water-soluble plate 35, thereby promoting the subsequent reaction to be more thorough, which helps the interphone to complete the floating action quickly and the loudspeaker to be exposed to the water surface in time, ensuring normal use in emergency environments.
[0079] Further as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , it is worth noting that the state adjustment assembly 40 includes:
[0080] a counterweight 41, the counterweight 41 is arranged at the bottom of the shell 10;
[0081] a gas bag two 42, the gas bag two 42 is arranged at the top of the shell 10, the top of the shell 10 is provided with a cavity 43 for accommodating the gas bag two 42, the cavity 43 and the reaction box 31 are provided with a gas pipe 44, the end of the gas pipe 44 extends into the reaction chamber, the end of the gas pipe 44 is provided with a filter screen, and the gas generated by the gas generating assembly 30 is preferentially inflated into the gas bag two 42 through the gas pipe 44;
[0082] It should be noted that when the walkie-talkie falls into water and the gas generating assembly 30 generates gas, the generated gas first enters the second airbag 42 at the top of the housing 10 through the air tube 44, which then inflates. As the second airbag 42 inflates, the counterweight 41 provides the necessary downward force, helping the walkie-talkie maintain a stable position in the water. In this way, the counterweight 41 and the second airbag 42 work together to shift the center of gravity of the walkie-talkie downward, ensuring that it maintains an upright position in the water.
[0083] When the intercom reaches the surface, buoyancy forces the speaker end of the intercom out of the water, while the rest of the device remains afloat thanks to the buoyancy of airbag 2 42. Due to its low center of gravity, the speaker end remains above the water, facilitating audio transmission and reception. This design ensures the intercom remains upright underwater, effectively improving sound transmissibility and device stability.
[0084] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
[0085] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, all of which fall within the scope of protection of the present invention.
