[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the present invention, the directions or positional relationships indicated by the terms "inside", "outside", "middle", etc. are based on the directions or positional relationships shown in the drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0030] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0031] In addition, the terms "disposed", "provided with", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0032] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0033] In the related art, the power on, volume and other buttons of mobile terminals usually use push-type buttons such as key shrapnel. This type of key shrapnel is usually a mechanical structure, and generally requires a through hole to be opened on the shell of the mobile terminal so that the key can at least partially protrude from the through hole for the user to press. In other words, it is difficult to avoid the generation of installation gaps when the current key shrapnel is installed in the shell of the mobile terminal, which is not conducive to the waterproof treatment of the mobile terminal. If the waterproof treatment at these installation gaps is not proper, it is easy to cause water to enter the mobile terminal, affecting the service life of the mobile terminal. In addition, the buttons on the outside of the shell of the mobile terminal protrude from the shell. When designing the appearance of the mobile terminal, the technicians also need to consider the button layout and the overall aesthetics, which is not convenient for the technicians to design the appearance of the mobile terminal.

[0034] Based on this, the utility model provides a waterproof key module and a mobile terminal, which eliminates the installation gap between the shell and the key when the key is installed in the shell, effectively reduces the risk of water entering the mobile terminal, and is beneficial to the overall waterproof design of the mobile terminal. In addition, the waterproof key module provided by the utility model can also hide the key when not in use, which can make the shell of the mobile terminal flatter, reduce the protruding part of the shell, and improve the appearance of the shell of the mobile terminal.

[0035] The technical solution of the utility model will be further described below in conjunction with embodiments and drawings.

[0036] Please also see Figure 1 and Figure 2 The utility model discloses a mobile terminal. The mobile terminal 100 includes a shell 1, a waterproof key module 3 and a processor 4. The shell 1 has an installation space 2. The processor 4 is arranged in the installation space 2. The waterproof key module 3 is arranged in the shell.

[0037] Furthermore, the waterproof key module 3 includes a magnetic soft wire 31, a magnetic member 32 and a sensor 33. The magnetic soft wire 31 has a relative connection end and a free end 31b, the connection end is arranged on the outer surface of the shell 1, and the free end 31b is stretchable relative to the outer surface of the shell 1. The magnetic member 32 is arranged in the installation space 2 and is arranged relative to the magnetic soft wire 31. The magnetic member 32 is used to keep the magnetic soft wire 31 in an extended state relative to the shell 1. The sensor 33 is also arranged in the installation space 2. The sensor 33 is electrically connected to the processor 4. The sensor 33 is used to send an operation signal to the processor 4 when the free end 31b is pressed, so as to realize the pressing function of the waterproof key module 3.

[0038] It is understandable that when the magnetic wire 31 is pressed, the free end 31b of the magnetic wire 31 will be pressed by the user and move closer to the shell 1, and the sensor 33 will detect the change in the distance from the free end 31b to the shell 1 or whether the magnetic part 32 rotates or moves, thereby generating an operation signal.

[0039] By arranging a magnetic flexible wire 31 on the outer surface of the shell 1 of the mobile terminal 100, and the magnetic flexible wire 31 is stretchable relative to the outer surface of the shell 1, the magnetic member 32 can be used to repel the magnetic flexible wire 31 with the same polarity, so that the magnetic flexible wire 31 is kept in a state of stretching outward relative to the shell 1 of the mobile terminal 100, so as to facilitate the user to press. In this way, the user can press the stretched magnetic flexible wire 31, so that the sensor 33 can detect that the magnetic flexible wire 31 is pressed or the magnetic member 32 is rotated or displaced due to the same polarity repulsion of the magnetic flexible wire, and then send an operation signal to the processor 4, thereby realizing the key function of the magnetic flexible wire 31.

[0040] It can be seen that by adopting the waterproof button module 3 and the mobile terminal 100 of the present application, while realizing the button function of the mobile terminal 100, since the magnetic wire 31 and the magnetic part 32 are not directly connected, there is no need to open a through hole or a through groove on the shell 1 to set the button for transmitting the operation signal, which effectively replaces the existing method of opening a hole on the shell 1 for the button, reduces the generation of installation gaps on the shell 1, reduces the possibility of water entering the mobile terminal 100, and is beneficial to the waterproof design of the mobile terminal 100.

[0041] Optionally, the mobile terminal 100 may include but is not limited to a mobile phone, a tablet computer, a phone watch, etc.

[0042] Take the mobile terminal 100 as a mobile phone as an example. Optionally, the housing 1 has a side surface, and the magnetic cord 31 of the waterproof key module 3 is arranged on the side surface. It can be understood that by arranging the magnetic cord 31 of the waterproof key module 3 on the side surface of the housing 1, the magnetic cord 31 can be used as a power on / off control key and a volume control key of the mobile terminal 100, which is convenient for users to press.

[0043] Please see again Figure 1In some embodiments, the mobile terminal 100 further includes a vibration structure 5, which is disposed in the installation space 2 and electrically connected to the processor 4. The processor 4 is also used to control the vibration structure 5 to vibrate according to the operation signal sent by the sensor 33. It can be understood that the waterproof key module 3 uses the magnetic soft wire 31 as the pressing part. When the user presses the magnetic soft wire 31, the pressing feedback brought by the magnetic soft wire 31 itself is small. By electrically connecting the vibration structure 5 to the processor 4, when the processor 4 receives the operation signal from the sensor 33 and the magnetic soft wire 31 is in a pressed state, the processor 4 will control the vibration structure 5 to vibrate, and the vibration can be transmitted to the housing 1. That is, when the user presses the magnetic soft wire 31, the housing 1 will vibrate together with the vibration structure 5. When the user presses the magnetic soft wire 31, the user can obtain more practical pressing vibration feedback, which is convenient for the user to understand whether the pressing is in place, thereby improving the user's key usage experience.

[0044] Exemplarily, the vibration structure 5 may be a vibration motor. When the magnetic cord 31 is pressed, the vibration part of the vibration motor vibrates under the control of the processor 4, and the vibration generated by the vibration motor is transmitted to the housing 1. When the user holds the mobile terminal 100 and presses the magnetic cord 31, the user can feel the vibration transmitted from the housing 1 at the same time.

[0045] In order to better explain how the waterproof key module 3 realizes the key function, the waterproof key module 3 of the present application will be introduced in detail below with reference to the accompanying drawings.

[0046] Please also read Figures 1 to 3 As can be seen from the above, the free end 31b can be extended relative to the outer surface of the housing 1. In one example, when the free end 31b approaches the housing 1, the sensor 33 detects that the distance between the free end 31b and the housing 1 has changed, and the sensor 33 will generate an operation signal and transmit the operation signal to the processor 4 to realize the key function. In another example, the magnetic wire 31 is kept in an extended state relative to the housing 1 under the repulsive force of the magnetic member 32. When the free end 31b of the magnetic wire 31 is pressed, since the end of the magnetic member 32 facing the free end 31b has the same polarity as the free end 31b, for example, both are N poles or S poles, the free end 31b will also generate a repulsive force on the magnetic member 32. In this way, even if the housing 1 is not provided with a through hole for installing the key, the key function can be realized by only using the property of repulsion between the magnetic wire 31 and the magnetic member 32, avoiding the situation of generating an installation gap due to the opening of a through hole in the housing 1 to set the key shrapnel, and reducing the possibility of water ingress to the mobile terminal 100.

[0047] In another example, if the magnetic member 32 is rotatably disposed in the installation space 2, the magnetic member 32 will rotate under the repulsive force. The sensor 33 detects the rotation of the magnetic member 32 under the repulsive force, and the sensor 33 also generates an operation signal and transmits the operation signal to the processor 4 to realize the key function.

[0048] Based on this example, the following will be described in detail.

[0049] Please also see Figure 2 and Figure 3 In some embodiments, the magnetic member 32 is rotatably disposed in the installation space 2, and the magnetic member 32 has a first magnetic pole end 32a and a second magnetic pole end 32b with different magnetic properties. The free end 31b includes a first posture and a second posture. In the first posture, the free end 31b extends relative to the outer surface of the shell 1, and in the second posture, the free end 31b is attached to the outer surface of the shell 1. The free end 31b is configured to switch from the first posture to the second posture under the action of pressing, and the processor 4 is also used to control the rotation of the magnetic member 32 according to the operation signal to switch the orientation of the first magnetic pole end 32a and the second magnetic pole end 32b relative to the free end 31b. When the first magnetic pole end 32a faces the free end 31b, the free end 31b maintains the first posture, and when the second magnetic pole end 32b faces the free end 31b, the free end 31b maintains the second posture. In this way, by utilizing the rotatable feature of the magnetic part 32, it is possible to easily switch the orientation of the first magnetic pole end 32a and the second magnetic pole end 32b relative to the free end 31b, thereby making it easier for the free end 31b to switch between the first posture and the second posture, which is beneficial to realizing the rapid switching of button functions, such as the switching between the operating function of a button and the hidden function of the button relative to the shell 1.

[0050] In one example, when the mobile terminal 100 is in a non-use state such as turning off the screen or shutting down, the magnetic cord 31 needs to be hidden relative to the housing 1. At this time, the processor 4 will control the magnetic member 32 to rotate so that the magnetic end of the magnetic member 32 with a different polarity from the free end 31b faces the free end 31b, and the free end 31b will be adsorbed on the housing 1, that is, the free end 31b maintains the second posture, and the magnetic cord 31 is also attached to the outer surface of the housing 1 as a whole, thereby hiding the magnetic cord 31. In this way, the protrusions on the outer surface of the mobile terminal 100 can be reduced, which is conducive to improving the overall aesthetics of the appearance of the mobile terminal 100.

[0051] In another example, when the user turns on the screen of the mobile terminal 100, the processor 4 controls the magnetic part 32 to face the free end 31b with the same polarity as the magnetic pole of the free end 31b, and the free end 31b will remain in the first state due to the repulsive force under the same polarity. In this way, the magnetic cord 31 will protrude relative to the housing 1 to form a part that can be pressed by the user, so that the user can press the magnetic cord 31 when using the mobile terminal 100 to achieve the operation of key control of the function of the mobile terminal 100.

[0052] It is understandable that the magnetic member 32 has a first magnetic pole 32a and a second magnetic pole 32b with different magnetic properties, and the magnetic cord 31 also has a fixed end 31a and a free end 31b with different magnetic poles. When one of the first magnetic pole 32a or the second magnetic pole 32b is configured to have the same polarity as the fixed end 31a, when one of the two is facing the free end 31b, the free end 31b will extend in a direction away from the side of the shell 1 due to the repulsive force generated by the same magnetic pole, so that the free end 31b maintains the first posture. On the contrary, the other magnetic pole with a different polarity will produce an attractive force due to the different polarity, and the free end 31b will be attached to the outer surface of the shell 1, so that the free end 31b remains in the second posture.

[0053] In some embodiments, the waterproof key module 3 further includes a rotating structure 34, the rotating structure 34 is arranged in the installation space 2, the magnetic member 32 is rotatably connected to the rotating structure 34, the rotating structure 34 is electrically connected to the processor 4, and the processor 4 is also used to control the rotating structure 34 to drive the magnetic member 32 to rotate according to the operation signal to switch the orientation of the first magnetic pole 32a and the second magnetic pole 32b relative to the free end 31b. It can be understood that the use of the rotating structure 34 to change the orientation of the different magnetic poles of the magnetic member 32 with respect to the free end 31b makes it easier to change the orientation of the magnetic pole of the magnetic member 32, so that the switching of the free end 31b between the first posture and the second posture will also be easier, so that the user can call it up at any time.

[0054] For example, the rotating structure 34 can be a motor. The motor has a rotating shaft, and the magnetic member 32 is connected to the rotating shaft. When the processor 4 controls the rotating shaft of the motor to rotate, the magnetic member 32 will rotate with the rotating shaft, thereby changing the orientation between the first magnetic pole 32a and the second magnetic pole 32b, so as to realize the change of the free end 31b between the first posture and the second posture.

[0055] See also Figure 2In some embodiments, the magnetic member 32 may be a bar magnet or a round magnet. In the following, the magnetic member 32 is taken as a bar magnet as an example, and the middle part of the bar magnet can be rotatably connected to the rotating structure 34. It can be understood that setting the magnetic member 32 as a bar magnet facilitates the magnetic member 32 to rotate with the rotating structure to adjust the orientation of the two magnetic poles. Setting the connection part between the magnetic member 32 and the rotating structure 34 as the middle part of the magnetic member 32 can make the magnetic field distribution of the magnetic member 32 more uniform, which is conducive to better maintaining the magnetic cord 31 in the first posture or the second posture.

[0056] In some embodiments, the sensor 33 includes a distance measuring sensor, which is located between the magnetic member 32 and the magnetic flexible wire 31. The distance measuring sensor is used to detect the distance between the end of the free end 31b and the outer surface of the housing 1 when the user presses the magnetic flexible wire 31, and when the distance is less than or equal to a preset value, an operation signal is generated and sent to the processor 4. It is understandable that when the user initially presses the free end 31b, the distance measuring sensor does not directly generate an operation signal. Only when the user presses the free end 31b and the distance between the free end 31b and the housing 1 reaches the preset value, an operation signal is generated, which can effectively prevent the user from accidentally touching.

[0057] It is understandable that the sensor 33 may also include a pressure sensor, which can detect the pressure exerted on the housing 1 when the user presses down the magnetic cord 31, thereby generating an operation signal to realize the key function.

[0058] In some embodiments, the preset value is 0-2mm. The preset value can be specifically 0mm, 1mm or 2mm. In actual settings, the larger the preset value, the smaller the distance the user presses the finger when he wants to achieve the pressing function, that is, the higher the sensitivity of the key. Conversely, the smaller the preset value, the closer the user's finger is to the housing 1 when pressing, and the lower the sensitivity of the key. It can be understood that by setting the preset value within the range of 0-2mm, the key has a lower sensitivity, which can effectively prevent the user from touching it by mistake.

[0059] In some embodiments, there are multiple magnetic flexible wires 31, and the length of each magnetic flexible wire 31 extending relative to the outer surface of the housing 1 is 2mm-4mm. The length of the magnetic flexible wire 31 can be specifically 2mm, 3mm or 4mm. It is understandable that since the magnetic flexible wire 31 is used as the pressable part of the waterproof key module 3, it is necessary to set up multiple magnetic flexible wires 31 to make it easier for users to press, and the pressing feel of the magnetic flexible wire 31 is relatively soft. Setting the length of the magnetic flexible wire 31 within 2mm-4mm can provide users with a more comfortable key pressing distance.

[0060] The waterproof button module and mobile terminal disclosed in the embodiments of the present invention are introduced in detail above. Specific examples are used in this article to illustrate the principle and implementation method of the present invention. The description of the above embodiments is only used to help understand the waterproof button module and mobile terminal of the present invention and their core ideas. At the same time, for general technical personnel in this field, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the present invention.
