Background

In recent years, smart phones have made remarkable progress, and in order to make the design more compact and reduce the cost, phone manufacturers generally design a volume up key (volume +) and a volume down key (volume-) as a whole. The conventional integrated volume key 101 is designed in a two-end hook 102 type (as shown in fig. 1), but the design is prone to the problem of key string, that is, when the volume up key is pressed, since the hook 102 is clamped on the housing at the other side to form a clamping point, the volume key is rotatably supported, so that the volume down key is driven to be triggered downwards, or the volume up key is triggered while the volume down key is pressed.

In order to solve the problem of the integrated volume key string, there are two processing methods in the industry, one of which is to separately design the volume up key 103 and the volume down key 104 (as shown in fig. 2). However, the volume up key and the volume down key are designed separately, which occupies more space and weakens the strength of the middle frame of the mobile phone, and since the space on the side is reduced after the volume up key and the volume down key are designed separately, the power key has to be designed on the other side of the mobile phone, which may affect the user experience, and since the volume up key and the volume down key are designed separately, the cost of the mobile phone may be increased. The second way is to increase the distance between the two volume keys 101, so that the length of the integrated volume key is increased (as shown in fig. 3), and when the volume up key is pressed, the displacement of the volume down key is reduced, so that the risk of key string is reduced. However, the lengthening of the volume keys can only reduce the risk of key string, but cannot fundamentally eliminate the risk of key string, and the lengthening of the keys may affect the appearance of the mobile phone.

The first switch 211 supports the first abutting portion 321 by a reverse acting force, so that the pressing portion 31 is supported by the reverse acting force of the first switch 211 at a joint with the first abutting portion 321 to form a lever fulcrum, and the pressing portion 31 (including the second pressing portion 312) located at the other side of the first abutting portion 321 tends to tilt outward of the housing 10, so that the second pressing portion 312 is not driven to be pressed down along with the pressing of the first pressing portion 311, thereby preventing a key string phenomenon. At this time, the second catching portion 332 abuts against the second fixing portion 432 as a supporting point, so as to prevent the second pressing portion 312 from tilting outward.

Similarly, when the second pressing portion 312 is pressed, the second abutting portion 322 near the second pressing portion 312 is pressed to move toward the circuit board 20, and acts on the second switch 212, so as to trigger the volume control circuit (e.g., volume down). The second switch 212 supports the second abutting portion 322 by a reverse acting force, so that the pressing portion 31 is supported by the reverse acting force of the second switch 212 at a joint with the second abutting portion 322 to form a lever fulcrum, and the pressing portion 31 (including the first pressing portion 311) at the other side of the second abutting portion 322 tends to tilt outward of the housing 10, so that the first pressing portion 311 is not driven to be pressed down along with the pressing down of the second pressing portion 312, and the phenomenon of key string is prevented. At this time, the first catching portion 331 abuts against the first fixing portion 431 to serve as a supporting point, so as to prevent the first pressing portion 311 from tilting outward.

Compared with the prior art, due to the existence of the hooks 102 at the two ends, the lever fulcrums are arranged at the two ends, so that the two switches can be triggered at the same time.

The terminal device 100 of the application, locate through the card portion 33 that holds button 30 two of button 30 support between the portion 32 (between volume upper key and the volume lower key promptly), guarantee to press first pressing portion 311 or second press the portion 312 time, the lever fulcrum is in the centre, prevent to press the other end of portion 31 to be pushed down by the lever drive and lead to the string key, on the basis that does not change button 30 overall length, the problem of string key has been eliminated completely, and the integral forming of button 30 has been maintained, compact structure has reduced occupation space, and the cost of processing is unchangeable basically.

Further, the seal may also be provided in the terminal device 200, 300 to improve its protective properties.

Further, the number of the key holes, the pressing portions, the supporting portions and the switches in the terminal devices 100, 200, 300 and 400 of the present application can be further set to three or more, correspondingly, the number of the clamping portions can be set to four or more, two clamping portions in one group are respectively disposed between two adjacent supporting portions, the number of the fixing members can be set to two or more, and it is sufficient to respectively fix two corresponding clamping portions.

Further, the two holding portions 33 between the two abutting portions 32 in the terminal devices 100, 200, 300, and 400 of the present application can also be integrated, and the corresponding fixing member 40 can respectively abut against the holding portions 33 at two sides of the holding portions 33 to fix the key 30 on the housing 10.

Further, the fixing member 40 in the terminal device 100, 200, 300, 400 of the present application may also be provided in two to fix two catches 33, respectively.

The terminal device can be widely applied to scenes needing key functions, particularly keys needing multiple control functions, and comprises but is not limited to electronic devices such as mobile phones, tablets, PCs, game machines, POS machines and cameras.

The terminal equipment that this application embodiment provided, through holding structural design between two key holes (between volume upper key and the volume lower key promptly), when guaranteeing to press splenium one end, the lever fulcrum is in the centre, prevent to press the other end of splenium and drive by the lever and push down and lead to the string key, on the basis that does not change the whole length of button, the problem of string key has been eliminated completely, and the integrated into one piece of button has been maintained, compact structure, occupation space has been reduced, and the cost of processing is unchangeable basically.

The above description is only an embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions within the technical scope of the present disclosure should be covered by the disclosure of the present application.
