Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Fig. 2 is a schematic diagram of a first terminal according to an embodiment of the present invention. Referring to fig. 2, an embodiment of the present invention provides a terminal having a housing 200.

In an embodiment of the present invention, the housing 200 may include: a first shell 201 and a second shell 202, wherein the first shell 201 has a first protrusion 2031 thereon, and the second shell 202 has a second protrusion 2032 thereon; when the first housing 201 is mated with the second housing 202, the first protrusion 2031 and the second protrusion 2032 are mated to form a first barrier 203, a space inside the housing 200 is divided into a first chamber 204 and a second chamber 205 by the first barrier 203, and the electronic component 200a of the terminal is disposed in the second chamber 205; the first housing 201 and the second housing 202 have a gap 206 therebetween, and the first chamber 204 is used for storing liquid entering from the gap 206. It should be noted that the electronic component 200a may represent an electronic component such as a circuit board that may be short-circuited when encountering a liquid.

In the embodiment of the invention, the terminal can be a mobile phone, a tablet computer, a smart watch and the like.

In the embodiment of the present invention, the first case 201 and the second case 202 may be understood as a half case.

In the embodiment of the present invention, the shape of the first protrusion 2031 on the first housing 201 may or may not be similar to the shape of the outer contour of the first housing 201.

For example, referring to fig. 3, if the terminal is a mobile phone, the outer contour of the housing 300 may be approximately regarded as a rectangle, and the contour of the first protrusion 310 (referring to fig. 3) may be similar to the outer contour of the housing 300 and may be approximately rectangular.

It should be noted that the second protrusion 2032 may conform to the contour of the first protrusion 2031, so that after the first housing 201 and the second housing 202 are butted, the first protrusion 2031 and the second protrusion 2032 may be butted. The first chamber 204 formed by the first housing 201 and the second housing 202 being butted together can be regarded as an annular chamber.

In the embodiment of the present invention, a gap 206 is formed between the first housing 201 and the second housing 202, and a gap 207 is formed at a joint of the first protrusion 2031 and the second protrusion 2032.

In embodiments of the present invention, after the terminal has fallen into the liquid, the liquid may enter the first chamber 204 inside the housing 200 through the slit 206, since the pressure of the liquid outside the housing 200 is greater than the pressure of the gas inside the housing 200. After the liquid in the first chamber 204 floods the gap 207, the liquid may enter the second chamber 205 through the gap 207, and the liquid may enter the second chamber 205 to cause short-circuit damage to the electronic component 200 a. Thus, compared with the prior art, the terminal provided by the embodiment of the invention can delay the time for liquid to enter the second chamber 205 provided with the electronic component 200a, and can improve the waterproof performance of the terminal.

In addition, in the embodiment of the present invention, after the terminal falls into the liquid, the liquid may enter the first chamber 204 inside the housing 200 through the slit 206, and after the liquid enters the first chamber 204, the space in the first chamber 204 for containing the gas may decrease, the gas in the first chamber 204 may be compressed, and the gas pressure in the first chamber 204 may increase. As the volume of liquid in the first chamber 204 increases, the space in the first chamber 204 containing gas further decreases, and the gas pressure in the first chamber 204 also increases until the gas pressure in the first chamber 204 gradually reaches equilibrium with the liquid pressure outside the housing 200, and the speed of liquid entering the first chamber 204 gradually decreases.

Further, although the gas in the first chamber 204 may also enter the second chamber 205 through the gap 207, since the opening of the gap 207 is small, the flow rate of the gas is also small. Furthermore, it is apparent that even though the gas in the first chamber 204 may enter the second chamber 205 through the gap 207, the gas pressure of the first chamber 204 may eventually gradually reach equilibrium with the liquid pressure outside the housing 200 as the volume of the liquid in the first chamber 204 increases. Thus, during analysis, the entry of gas into the second chamber 205 through the gap 207 may be ignored.

It should be noted that the time of the process from the entry of the terminal into the liquid to the sinking of the bottom of the container containing the liquid is generally short, so that the volume of liquid entering the terminal during this process is limited, and the entry of liquid during this process can be disregarded because of the provision of the first chamber 204 for storing the liquid entering the housing from said slit 206. In addition, in the embodiment of the present invention, during the process of designing the terminal, the center of gravity of the terminal may be adjusted so that the first casing of the terminal faces downward or the second casing of the terminal faces downward after the terminal falls into the liquid. For example, if the terminal is a cell phone, the terminal will typically sink to the bottom of a container holding the liquid, with either the first housing or the second housing facing downward. In the following description, the process of water intake of the terminal can also be analyzed with the terminal sunk in the bottom of the container containing the liquid, with the first or second casing facing downwards, and will not be explained one by one hereafter.

In this way, the liquid entering the terminal can be stored in the first chamber 204, so that the time for the liquid to enter the second chamber 205 provided with the electronic element 200a can be delayed, the time for a fault that the electronic element 200a is damaged after the liquid enters the second chamber 205 can be delayed, and the waterproof performance of the terminal can be improved. Thus, if the terminal can be fished out of the liquid within a certain time after the terminal falls into the liquid, the terminal may not be damaged.

Fig. 4 is a schematic diagram of a second terminal according to an embodiment of the present invention. Referring to fig. 4, in an embodiment of the present invention, on the basis of the terminal shown in fig. 2, at least one first one-way gate 208 may be disposed on the first barrier 203. Gas or liquid in the second chamber 205 may enter the first chamber 204 through the first single-pass gate 208, while gas or liquid in the first chamber 204 cannot enter the second chamber 205 through the first single-pass gate 208.

As will be readily understood, heat-generating components, such as circuit boards, etc., which generate heat during operation, are generally present inside the terminal device. Therefore, after the terminal falls into the liquid, certain heat can be generated by heating parts such as a circuit board and the like in the terminal equipment in the working process, the temperature in the terminal equipment can be increased, and the air pressure in the terminal equipment can be increased accordingly.

In the embodiment of the present invention, the heat-generating components such as the circuit board in the second chamber 205 may generate a certain amount of heat during the operation process, so that the air pressure of the second chamber 205 may also increase, and when the air pressure of the second chamber 205 is greater than the air pressure of the first chamber 204, the air in the second chamber 205 may enter the first chamber 204 through the first one-way door 208, so that the air pressure of the first chamber 204 may increase, and the speed at which the liquid outside the housing 200 enters the first chamber 204 through the gap 206 may be reduced, so that the time at which the liquid in the first chamber 204 enters the second chamber 205 provided with the electronic component 200a through the gap 207 may be delayed.

It should be noted that, in the embodiment shown in fig. 4, only one first single-pass gate 208 is disposed on the first protrusion 2031, and it is easily understood that other first single-pass gates 208 may be disposed at other positions (including the second protrusion 2032) on the first baffle 203. Obviously, the number of the first single-pass gates 208 may be one or more than one.

In this way, after the gas in the second chamber 205 is heated by the heating component in the second chamber 205, the gas can enter the first chamber 204 through the first one-way door 208, so that the gas pressure in the first chamber 204 can be increased, the speed of the liquid entering the first chamber 204 can be reduced, the time of the liquid entering the second chamber 205 provided with the electronic component 200a through the gap 207 can be delayed, and the waterproof performance of the terminal can be improved.

Fig. 5 is a schematic diagram of a third terminal according to an embodiment of the present invention. Referring to fig. 5, in an embodiment of the present invention, at least one through hole 209 may be provided on the first barrier 203 on the basis of the terminal shown in fig. 4. The through hole 209 may communicate the first chamber 204 and the second chamber 205.

In the embodiment of the present invention, the opening of the through hole 209 is small, and the opening of the through hole 209 is slightly larger than the opening of the gap 207, so that the gas in the first chamber 204 can slowly enter the second chamber 205 through the through hole 209.

It should be noted that the gas in the second chamber 205 may enter the first chamber 204 through the first single-pass gate 208, and the gas in the first chamber 204 may also enter the second chamber 205 through the through hole 209, but the flow rate of the gas entering the first chamber 204 through the first single-pass gate 208 may be greater than the flow rate of the gas entering the second chamber 205 through the through hole 209. No one explanation is provided in the following description.

In the embodiment of the present invention, after the terminal is sunk into the bottom of the container for containing the liquid, the liquid can enter the first chamber 204 inside the housing 200 through the slit 206 because the pressure of the liquid outside the housing 200 is greater than the pressure of the gas in the first chamber 204, and after the liquid enters the first chamber 204, the gas in the first chamber 204 is compressed, and the pressure of the gas in the first chamber 204 is increased. When the gas pressure of the first chamber 204 is higher than the gas pressure of the second chamber 205, the gas in the first chamber 204 may slowly enter the second chamber 205 through the through hole 209, and the gas pressure in the second chamber 205 may be increased, so that the accumulated water near the gap 207 may be prevented from being squeezed into the second chamber 205.

In the embodiment of the present invention, the heat-generating components such as the circuit board in the second chamber 205 may generate a certain amount of heat during the working process, so that the air pressure of the second chamber 205 may also increase, and when the air pressure of the second chamber 205 is greater than the air pressure of the first chamber 204, the air in the second chamber 205 may enter the first chamber 204 through the first one-way door 208, so as to increase the air pressure in the first chamber 204, decrease the speed at which the liquid outside the housing 200 enters the first chamber 204 through the gap 206, and further increase the waterproof performance of the terminal device.

In an embodiment of the present invention, the gas in the first chamber 204 may slowly enter the second chamber 205 through the through hole 209. In this way, the gas in the first chamber 204 and the gas in the second chamber 205 can be made to flow, so that the gas in the first chamber 204 and the gas in the second chamber 205 can be heated, the pressure of the gas in the first chamber 204 and the second chamber 205 can be increased, and the speed of the liquid outside the housing 200 entering the interior of the housing 200 can be reduced. And further the waterproof performance of the terminal equipment can be further improved.

It should be noted that the through holes 209 may be disposed at any position on the first baffle 203, and of course, the number of the through holes 209 may be one or more than one.

In this way, after the gas in the second chamber 205 is heated by the heating part in the second chamber 205, the gas can enter the first chamber 204 through the first single-pass door 208, so that the gas pressure in the first chamber 204 can be increased, in addition, the gas in the first chamber 204 can also enter the second chamber 205 through the through hole 209 to be heated, so that the gas pressures in the first chamber 204 and the second chamber 205 can be increased, the speed of the liquid entering the first chamber 204 can be reduced, the time of the liquid entering the second chamber 205 through the gap 207 can be delayed, and the waterproof performance of the terminal can be improved.

It should be noted that, referring to fig. 5, in the embodiment of the present invention, the first single-pass door 208 shown in fig. 5 may be eliminated, and after the gas in the second chamber 205 is heated by the heating component in the second chamber 205, the gas may slowly enter the first chamber 204 through the through hole 209, so that the gas pressure of the first chamber 204 may be raised, thereby the speed of the liquid entering the first chamber 204 may be reduced, the time of the liquid entering the second chamber 205 through the gap 207 may be delayed, and the waterproof performance of the terminal may be improved. Obviously, the number of the through holes 209 may be one or more than one.

Fig. 6 is a schematic diagram of a fourth terminal according to an embodiment of the present invention. Referring to fig. 6, in an embodiment of the present invention, based on the terminal shown in fig. 5, the housing 200 further includes a second baffle 210 extending from the first baffle 203, and the second baffle 210 divides the first chamber 204 into a third chamber 2041 and a fourth chamber 2042.

In the embodiment of the present invention, after the terminal is sunk to the bottom of the container for containing the liquid, since the pressure of the liquid outside the housing 200 is higher than the pressure of the gas in the third chamber 2041, the liquid can enter the third chamber 2041 inside the housing 200 through the gap 206, and after the liquid enters the third chamber 2041, the gas in the third chamber 2041 can be compressed, so that the pressure of the gas in the third chamber 2041 can be increased. As the pressure within the third chamber 2041 gradually equalizes with the pressure of the fluid outside the housing 200, the rate at which the fluid enters the third chamber 2041 gradually decreases.

In the embodiment of the present invention, the heat-generating components such as the circuit board in the second chamber 205 may generate a certain amount of heat during the working process, so that the air pressure of the second chamber 205 may also increase, and when the air pressure of the second chamber 205 is greater than that of the fourth chamber 2042, the air in the second chamber 205 may enter the fourth chamber 2042 through the first single-pass door 208. In this way, when the air pressure inside the housing 200 is higher than the air pressure outside, the air in the fourth chamber 2042 and the second chamber 205 can be prevented from entering the third chamber 2041 and then escaping to the outside of the housing 200 through the gap 206, which causes the air pressure inside the housing 200 to decrease. In addition, the pressure in the second chamber 205 increases, which prevents standing water near the gap 207 from being squeezed into the second chamber 205.

It should be noted that, in the embodiment shown in fig. 6, only one first single-pass gate 208 and one through hole 209 are disposed on the first protrusion 2031, and it is easy to understand that other first single-pass gates 208 and other through holes 209 may be disposed at other positions (including on the second protrusion 2032) on the first baffle 203. In addition, if the second protrusion 2032 is also provided with the first single pass door 208 and the through hole 209, the second shutter 210 may also extend from the second protrusion 2032. Obviously, the number of the first single-pass gates 208 may be one or more than one, and the number of the through holes 209 may be one or more than one.

Further, referring to fig. 6, in the embodiment of the present invention, if the second housing 202 is downward after the terminal is sunk into the bottom of the container containing the liquid, the third chamber 2041 may also store the liquid entering through the slit 206. Certain heat can be generated by heating parts such as the circuit board in the second chamber 205 in the working process, so that the air pressure of the second chamber 205 can be increased, and accumulated water near the gap 207 can be prevented from being extruded into the second chamber 205.

In this manner, the third chamber 2041 can be utilized to store liquid entering through the aperture 206. In addition, after the gas in the second chamber 205 is heated by the heat generating component in the second chamber 205, the gas pressure in the second chamber 205 can be increased, and the water accumulated near the gap 207 can be prevented from being squeezed into the second chamber 205. This can improve the waterproof performance of the terminal.

It should be noted that, referring to fig. 6, in the embodiment of the present invention, on the basis of fig. 6, a certain number of through holes 209 may be disposed on the second protrusion 2032, so that the through holes 209 disposed on the second protrusion 2032 may communicate with the third chamber 2041 and the second chamber 205, so as to heat the gas in the third chamber 2041, and increase the air pressure in the third chamber 2041, so as to reduce the speed at which the liquid outside the housing 200 enters the third chamber 2041 through the gap 206, and delay the time at which the liquid enters the second chamber 205, so as to improve the waterproof performance of the terminal.

It should be noted that, referring to fig. 6, in the embodiment of the present invention, the first single-pass door 208 may not be provided, and only a certain number of through holes 209 may be provided on the first protrusion 2031 and/or the second protrusion 2032. The waterproof and waterproof of the terminal in the above embodiment can refer to the foregoing, and the description is omitted here.

Fig. 7 is a schematic diagram of a fifth terminal according to an embodiment of the present invention. Referring to fig. 7, in an embodiment of the present invention, at least one second one-way gate 211 may be provided on the second barrier 210 on the basis of the terminal shown in fig. 6. Gas or liquid in the third chamber 2041 can enter the fourth chamber 2042 through the second single pass door 211, while gas or liquid in the fourth chamber 2042 cannot enter the third chamber 2041 through the second single pass door 211.

In the embodiment of the present invention, after the terminal is sunk to the bottom of the container for containing the liquid, since the pressure of the liquid outside the housing 200 is higher than the pressure of the gas in the third chamber 2041, the liquid can enter the third chamber 2041 inside the housing 200 through the gap 206, after the liquid enters the third chamber 2041, the pressure in the third chamber 2041 can be increased, when the pressure in the third chamber 2041 is higher than the pressure in the fourth chamber 2042, the second one-way door 211 can be opened, and the liquid can enter the fourth chamber 2042 through the second one-way door 211. Until the air pressure in the third chamber 2041 gradually reaches equilibrium with the water pressure outside the housing 200, the rate of liquid entering the third chamber 2041 gradually decreases.

After the liquid enters the fourth chamber 2042 through the second single-pass door 211, the air pressure in the fourth chamber 2042 may be increased, and when the air pressure in the fourth chamber 2042 is greater than the air pressure in the second chamber 205, the gas may enter the second chamber 205 through the through hole 209, so that the air pressure in the second chamber 205 may be increased. The increased air pressure in the second chamber 205 prevents water near the gap 207 from being squeezed into the second chamber 205.

In the embodiment of the present invention, the heat-generating components such as the circuit board in the second chamber 205 may generate a certain amount of heat during the working process, so that the air pressure of the second chamber 205 may also increase, and when the air pressure of the second chamber 205 is greater than the air pressure of the fourth chamber 2042, the air in the second chamber 205 may enter the fourth chamber 2042 through the first single-pass door 208.

In this way, since the gas in the fourth chamber 2042 cannot enter the third chamber 2041 through the second single-pass door 211, the gas in the fourth chamber 2042 can be prevented from entering the third chamber 2041 through the second single-pass door 211 and then overflowing to the outside of the housing 200 through the gap 206, which results in a decrease in the pressure inside the housing 200.

It should be noted that, in the embodiment shown in fig. 7, only one second single-pass gate 211 is disposed on the second baffle 210, and it is easy to understand that other second single-pass gates 211 may be disposed at other positions on the second baffle 210. It will be readily appreciated that other first single-pass doors 208 and through-holes 209 may be provided at other locations on the first bezel 203, including on the second protrusion 2032. In addition, if the second protrusion 2032 is also provided with the first single pass door 208 and the through hole 209, the second shutter 210 may also extend from the second protrusion 2032. Obviously, the number of the first single-pass gates 208 may be one or more than one, and the number of the through holes 209 may be one or more than one.

Further, referring to fig. 7, in the embodiment of the present invention, if the second housing 202 is downward after the terminal is sunk into the bottom of the container containing the liquid, the third chamber 2041 may also store the liquid entering from the slit 206. Certain heat can be generated by heating parts such as the circuit board in the second chamber 205 in the working process, so that the air pressure of the second chamber 205 can be increased, and accumulated water near the gap 207 can be prevented from being extruded into the second chamber 205. The second single-pass door 211 may also prevent the gas in the fourth chamber 2042 from entering the third chamber 2041 through the second single-pass door 211 and then escaping to the outside of the housing 200 through the gap 206.

In this manner, the third chamber 2041 or the fourth chamber 2042 can be utilized to store liquid that enters through the aperture 206. In addition, after the gas in the second chamber 205 is heated by the heat generating component in the second chamber 205, the gas pressure in the second chamber 205 can be increased, and the water accumulated near the gap 207 can be prevented from being squeezed into the second chamber 205. This can improve the waterproof performance of the terminal.

It should be noted that, referring to fig. 7, in the embodiment of the present invention, on the basis of fig. 7, a certain number of through holes 209 may be disposed on the second protrusion 2032, so that the through holes 209 disposed on the second protrusion 2032 may communicate with the third chamber 2041 and the second chamber 205, so as to heat the gas in the third chamber 2041, and increase the air pressure in the third chamber 2041, so as to reduce the speed at which the liquid outside the housing 200 enters the third chamber 2041 through the gap 206, and delay the time at which the liquid enters the second chamber 205, so as to improve the waterproof performance of the terminal.

Fig. 8 is a schematic diagram of a sixth terminal according to an embodiment of the present invention. Referring to fig. 8, in the embodiment of the present invention, on the basis of the terminal shown in fig. 7, if another first one-way door 208 and a through hole 209 are also provided on the second protrusion 2032, a third baffle 212 may extend from the second protrusion 2032. Third baffle 212 may divide third chamber 2041 into a first subchamber 2041a and a second subchamber 2041 b. In addition, at least one third single-pass gate 213 may be disposed on the third baffle 212, and the gas or liquid in the first sub-chamber 2041a may enter the second sub-chamber 2041b through the third single-pass gate 213, and the gas or liquid in the second sub-chamber 2041b may not enter the first sub-chamber 2041a through the third single-pass gate 213.

In the embodiment of the present invention, if the terminal sinks into the bottom of the container for containing the liquid, the first housing 201 faces downward, the liquid outside the housing 200 can enter the first sub-chamber 2041a through the gap 206, so that the air pressure in the first sub-chamber 2041a can be raised, and when the air pressure in the first sub-chamber 2041a is higher than the air pressure in the fourth sub-chamber 2042, the liquid in the first sub-chamber 2041a can enter the fourth sub-chamber 2042 through the second one-way door 211.

After the liquid enters the fourth chamber 2042, the air pressure of the fourth chamber 2042 can be increased, and when the air pressure of the fourth chamber 2042 is greater than the air pressure of the second chamber 205, the gas in the fourth chamber 2042 can enter the second chamber 205 slowly through the through hole 209, so that the air pressure of the second chamber 205 can be increased, and therefore, accumulated water near the gap 207 can be prevented from being squeezed into the second chamber 205.

In the embodiment of the present invention, the heat-generating components such as the circuit board in the second chamber 205 may generate a certain amount of heat during the working process, so that the air pressure of the second chamber 205 may also rise, and when the air pressure of the second chamber 205 is greater than the air pressure of the fourth chamber 2042, the air in the second chamber 205 may enter the fourth chamber 2042 through the first single-pass door 208; the gas in the fourth chamber 2042 may also enter the second chamber 205 through the through holes 209 so that the gas may circulate between the two chambers. When the gas pressure of the second chamber 205 is higher than the gas pressure of the second sub-chamber 2041b, the gas in the second chamber 205 can enter the second sub-chamber 2041b through the first one-way door 208; gas in the second sub-chamber 2041b may also enter the second chamber 205 through the through holes 209 so that the gas may circulate between the two chambers. In this way, the gas in the second chamber 205, the fourth chamber 2042 and the second sub-chamber 2041b can be heated.

Due to the presence of the second single-pass door 211 and the third single-pass door 213, the gas in the second chamber 205, the fourth chamber 2042, and the second sub-chamber 2041b can be prevented from entering the first sub-chamber 2041a, and then overflowing to the outside of the housing 200 through the gap 206, resulting in a decrease in the gas pressure inside the housing 200.

It should be noted that, if the terminal sinks into the bottom of the container for containing the liquid, the second housing 202 faces downward, and a similar waterproof effect can be achieved, which is not described again.

In this way, the fourth chamber 2042 or the second subchamber 2041b can be used to store liquid entering through the gap 206. In addition, after the gas in the second chamber 205 is heated by the heat generating component in the second chamber 205, the gas pressure in the second chamber 205 can be increased, and the water accumulated near the gap 207 can be prevented from being squeezed into the second chamber 205. This can improve the waterproof performance of the terminal.

In reference to fig. 8, in the embodiment of the present invention, the second single-pass door 211 may not be disposed on the second baffle 210, and the third single-pass door 213 may not be disposed on the third baffle 212, in which case, the terminal is waterproof.

Referring to fig. 8, in an embodiment of the present invention, the second baffle 210 may extend from the first protrusion 2031 or may extend from the second protrusion 2032; the third barrier 212 may extend from the first protrusion 2031 and may also extend from the second protrusion 2032. In the above case, the way of waterproofing the terminal can be seen in the foregoing, and is not described herein again.

In the embodiment of the present invention, if the third baffle 212 divides the third cavity 2041 or the fourth cavity 2042 into two sub-cavities, the gap 206 is communicated with one of the two sub-cavities. When the sub-chamber communicated with the gap 206 is communicated with the second chamber 205 through the through hole 209, after the gas in the second chamber is heated by the heating part in the second chamber 205, the gas pressure in the second chamber 205 can be increased, and when the gas pressure in the second chamber 205 is greater than the gas pressure in the sub-chamber communicated with the gap 206, the gas in the second chamber 205 can slowly enter the sub-chamber communicated with the gap 206 through the through hole 209, so that the gas pressure in the sub-chamber can be increased, the speed of liquid entering the sub-chamber through the gap 206 can be reduced, and the time of liquid entering the second chamber can be prolonged.

In particular, for the system embodiment, since it is substantially similar to the method embodiment, the description is simple, and for the relevant points, reference may be made to the partial description of the method embodiment.
