[0017] 2. A handheld communication terminal with a protection function according to the present invention, through a salvage assistance component one and a salvage assistance component two, when the casing floats on the water surface, uses the blades to paddle water and change the paddling direction to make the casing approach the user, avoiding it floating away from the user along with the water flow. At the same time, the angle of the storage shell can be adjusted according to the angle of the floating casing, and then the scissor telescopic mechanism is used to drive the telescopic block to move out of the storage shell, making the telescopic block close to the user's hand or the salvage tool to provide a force application point for the user. In this way, by making the casing approach the user and providing a force application point for the user, the user can salvage the device more quickly.

[0018] 3. A handheld communication terminal with a protection function according to the present invention, by arranging soft pads at the four corners of the casing, when the casing falls from a height, the soft pads can play a buffering and protecting effect on the main body of the casing, preventing the casing from being damaged due to hitting the ground.

Specific embodiments

[0022] Next, the technical solution of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 - 11 , the present invention provides a technical solution: a handheld communication terminal with a protection function, including a machine shell 1, a display screen 5 and a keyboard 6 are arranged on one side of the machine shell 1, and a water immersion anti-sinking mechanism is also arranged on the machine shell 1; The water immersion anti-sinking mechanism includes a support seat 27 fixedly connected to one side of the inner cavity wall of the machine shell 1, a roller 28 is rotatably arranged at one end of the support seat 27, an airbag 4 is fixedly connected to one side of the roller 28, a shell cover 3 is fixedly connected to one end of the airbag 4, a through hole 8 is arranged on one side of the machine shell 1, the shell cover 3 and the through hole 8 are of matching specifications, an installation ring 19 is fixedly connected to one side of the inner cavity wall of the machine shell 1, a gas storage tank 18 is fixedly connected to one side of the installation ring 19, the air outlet end of the gas storage tank 18 is communicated with a hose 10, and a valve 24 is arranged at the air outlet end of the gas storage tank 18, one end of the hose 10 is communicated with the airbag 4, an air release port 21 is arranged on one side of the airbag 4, a water pressure sensor 12 is arranged on the outer side of one side of the machine shell 1, and a cover plate 2 is rotatably arranged on one side of the machine shell 1.

[0024] In this embodiment, asFigure 3 , Figure 5 , Figure 6 As shown, a motor 3 29 is fixedly connected to one side of the support seat 27 , and an output end of the motor 3 29 is fixedly connected to one end of the rotating roller 28 .

[0025] Slide rods 11 are fixedly connected to both sides of the shell cover 3 , and the slide rods 11 are slidably connected to the sleeves 20 , which are plugged and slidably connected to the slide rods 11 .

[0026] A plurality of magnetic blocks 22 are arranged around one side of the shell cover 3, and a plurality of magnetic blocks 1 9 are arranged around the through hole of the shell 1. The magnetic blocks 1 9 and the magnetic blocks 2 22 are attracted to each other.

[0027] Specifically, when the existing handheld communication terminal is used for water operations, the user may lose the device due to the turbulence of the ship and drop it into the water. If the user fails to salvage it in time, the communication terminal will sink to the bottom of the water, causing losses.

[0028] Therefore, in order to solve the above problems, when using the present embodiment, the housing 1 is held in the hand, and communication can be performed through the display screen 5 and the keyboard 6. In the initial state, the housing cover 3 is adsorbed on the through hole 8 of the housing 1 through the magnetic block 1 9 and the magnetic block 2 22. When the housing 1 accidentally falls into the water, the water pressure sensor 12 will detect the water fall information and transmit the information to the controller. The valve 24 opens, and the compressed gas in the gas tank 18 is passed into the airbag 4 through the hose 10. The airbag 4 will push the housing cover 3 open due to expansion. The airbag 4 contacts the water and floats on the water surface, which can prevent the housing 1 from continuing to sink, thereby avoiding the housing 1 from sinking directly to the bottom of the water, providing the user with time for salvage, and having a good protection effect. When the airbag 4 is stored, it does not take up space, and Moreover, after the casing 1 is salvaged, the airbag 4 can be deflated through the air release port 21 to reduce the volume of the airbag 4, and then the motor 3 29 drives the roller 28 to rotate, so that the airbag 4 can be stored in the casing 1. Moreover, when the shell cover 3 moves, the slide bar 11 and the sleeve 20 slide relative to each other, which can guide the shell cover 3, so that the shell cover 3 can be smoothly moved to the through hole 8, and the magnetic block 1 9 and the magnetic block 2 22 are accurately adsorbed, which is convenient for subsequent use. Moreover, after the shell cover 3 covers the through hole 8, the roller 28 is reversed again to unwind the already wound airbag 4 again, so as to avoid the situation that the airbag 4 is difficult to be removed from the casing 1 due to being wrapped around the roller 28 when it is inflated next time, and the gas tank 18 can be replaced by opening the cover plate 2.

[0029] In this embodiment, Figure 3 , Figure 7 , Figure 8 , Figure 11 As shown, a salvage auxiliary component 1 is also provided at the bottom of the housing 1; The first salvage assistance component includes a storage shell 15 rotatably arranged at the bottom of the housing 1. One end of the inner cavity of the storage shell 15 is provided with a scissor telescopic mechanism 17, and one end of the scissor telescopic mechanism 17 is fixedly connected with a telescopic block 16.

[0030] One side of the bottom of the housing 1 is fixedly connected with a fourth motor 30, and the output end of the fourth motor 30 is fixedly connected with one side of the storage shell 15.

[0031] A second salvage assistance component is further arranged on the housing cover 3; The second salvage assistance component includes a rotating plate 13 rotatably arranged on one side of the housing cover 3. Both ends of the inner cavity of the rotating plate 13 are rotatably provided with a rotating shaft 25, and a plurality of blades 14 are fixedly connected around the rotating shaft 25.

[0032] One side of the housing cover 3 is fixedly connected with a first motor 23, and the output end of the first motor 23 is fixedly connected with one side of the rotating plate 13.

[0033] One end of the rotating plate 13 is fixedly connected with a second motor 26, and the output end of the second motor 26 is fixedly connected with one end of the rotating shaft 25.

[0034] Specifically, in the above embodiment, although the housing 1 can be prevented from sinking by inflating the airbag 4, when the housing 1 floats on the water surface, it is easy to drift away from the user along with the water flow. Moreover, during salvage, since the housing 1 may be submerged in the water surface, it is not easy to find the force application point, resulting in difficult salvage; Therefore, to solve the above problems, in the use of this embodiment, when the housing 1 floats on the water surface, the user can control the operation of the electric control components on the housing 1 through the mobile phone APP. If the housing 1 drifts with the water flow, the blades 14 can be made to paddle water by driving the rotation of the rotating shaft 25 by the second motor 26. At the same time, by driving the rotation of the rotating plate 13 by the first motor 23, the paddling direction can be changed to make the housing 1 approach the user, avoiding the situation that when the housing 1 floats on the water surface, it is easy to drift away from the user along with the water flow. Moreover, according to the angle of the housing 1 during drifting, the fourth motor 30 can be used to drive the rotation of the storage shell 15 to adjust the angle of the storage shell 15. At the same time, the scissor telescopic mechanism 17 is used to drive the telescopic block 16 to move out of the storage shell 15, so that the telescopic block 16 approaches the user's hand or the salvage tool, providing a force application point for the user. That is, by making the housing 1 approach the user and providing a force application point for the user, the salvage difficulty can be reduced, so that the user can salvage the equipment more quickly.

[0035] In this embodiment, as shown in FIGS. 1, Figure 4 , Figure 9 as shown, soft pads 7 are arranged at the four corners of the housing 1.

[0036] Specifically, by setting soft pads 7 at the four corners of the housing 1, when the housing 1 falls from a height, the soft pads 7 can buffer and protect the main body of the housing 1, preventing the housing 1 from being damaged due to hitting the ground.

[0037] Working principle: Hold the housing 1, and communication work can be carried out through the display screen 5 and the keyboard 6. And in the initial state, the housing cover 3 is adsorbed at the through hole 8 of the housing 1 through the magnetic attraction block one 9 and the magnetic attraction block two 22. When the housing 1 accidentally falls into water, the water pressure sensor 12 will detect the falling water information and transmit the information to the controller, the valve 24 opens, and the compressed gas in the gas storage tank 18 will pass through the hose 10 into the airbag 4. The airbag 4 will be pushed open due to expansion, and the airbag 4 will contact the water and float on the water surface, which can prevent the housing 1 from continuing to sink, thus avoiding the housing 1 directly sinking to the bottom of the water, providing the user with the salvage time, with good protection effect, and when the airbag 4 is stored, it does not occupy space. And after the housing 1 is salvaged, the airbag 4 can be deflated through the air release port 21 to reduce the volume of the airbag 4, and then the roller 28 is driven to rotate by the motor three 29, and the airbag 4 can be stored in the housing 1. And when the housing cover 3 moves, the sliding rod 11 and the sleeve 20 slide relative to each other, which can play a guiding role for the housing cover 3, so that the housing cover 3 can move smoothly to the through hole 8, and the magnetic attraction block one 9 and the magnetic attraction block two 22 are accurately adsorbed, which is convenient for subsequent use. And after the housing cover 3 covers the through hole 8, the roller 28 rotates in reverse again, and the airbag 4 that has been wound is unwound again, avoiding the situation that when the airbag 4 is inflated next time, it is difficult to move out of the housing 1 because it is wound around the roller 28. And the gas storage tank 18 can be replaced by opening the cover plate 2. When the housing 1 floats on the water surface, the user can control the electric control components on the housing 1 to work through the mobile phone APP. If the housing 1 drifts with the water flow, the blade 14 can be made to paddle water by driving the rotating shaft 25 to rotate by the motor two 26. At the same time, by driving the rotating plate 13 to rotate by the motor one 23, the paddling direction can be changed to make the housing 1 approach the user, avoiding the situation that when the housing 1 floats on the water surface, it is easy to drift away from the user with the water flow. And according to the angle when the housing 1 drifts, the storage shell 15 can be driven to rotate by the motor four 30 to adjust the angle of the storage shell 15. At the same time, the scissor telescopic mechanism 17 is used to drive the telescopic block 16 to move out of the storage shell 15, so that the telescopic block 16 is close to the user's hand or the salvage tool, providing a force point for the user. That is, by making the housing 1 approach the user and providing a force point for the user, the salvage difficulty can be reduced, so that the user can salvage the equipment more quickly; by setting soft pads 7 at the four corners of the housing 1, when the housing 1 falls from a height, the soft pads 7 can buffer and protect the main body of the housing 1, preventing the housing 1 from being damaged due to hitting the ground.
