Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
As shown in fig. 2 to 7, the present embodiment provides a key assembly and a mobile terminal including the same. As shown in fig. 2 and 3, the key assembly includes: the key comprises a key body 1 and a bolt 2, wherein the key body 1 can move to a first position along a first direction and can move to a second position along a second direction, and the first direction is opposite to the second direction. Specifically, in some preferred embodiments, the key body 1 is disposed on the mobile terminal, the key body 1 is located at a first position under a normal condition, and when an external force is applied to the key body 1, the key body 1 moves to a second position and can trigger a key signal. The latch 2 is used for limiting the key body 1 to move from the first position to the first direction so as to prevent the key body 1 from being separated from the mobile terminal.
When the key body 1 is at the first position, the pin 2 is connected with the key body 1 in a clamping manner (as shown in fig. 4), and when the key body 1 is at the second position, the pin 2 can be pulled away from the key body 1 (as shown in fig. 5). Compare in prior art button adoption joint at the mode of casing 3, this embodiment utilizes 2 fixed button bodies of bolt 1 comparatively firm, and button body 1 is difficult to drop. Under normal use state, bolt 2 and 1 joint of button body, button body 1 is by firm fixed, and bolt 2 also can't be taken out. When needing dismouting button subassembly, only need to make button body 1 remove towards the second direction, bolt 2 breaks away from the joint with button body 1, can take out bolt 2 (as shown in fig. 6), takes out button body 1 afterwards. The dismounting process of the key body 1 only needs to move along the first direction and the second direction, so that a gap does not need to be left between the key body 1 and the mounting hole 34 of the shell 3, and sealing is facilitated. And the button body 1 can be installed outside the shell 3, so when the button body 1 is disassembled and assembled, the shell 3 does not need to be opened, and the disassembly and the assembly are convenient.
The key body 1 has a limiting surface 111 facing the first direction, and the plug 2 is disposed opposite to the limiting surface 111. The plug 2 can block the limiting surface 111 in the first direction, so that when the key body 1 is located at the first position, the plug does not move to the first direction. In the embodiment, the housing 3 is provided with a pin hole 31, and the plug pin 2 can be fittingly inserted into the pin hole 31 and is disposed opposite to the limiting surface 111, wherein the extending direction of the pin hole 31 is perpendicular to the first direction.
Specifically, in the present embodiment, the key body 1 is provided with a limiting groove 11, the limiting surface 111 is disposed in the limiting groove 11, and the plug 2 is disposed in the limiting groove 11. The limiting surface 111 is a part of the wall surface of the limiting groove 11, and the bolt 2 can be clamped with the limiting groove 11, so that the key body 1 is limited.
The plug 2 includes a first protrusion 21 protruding toward the second direction, and when the key body 1 is at the first position, the first protrusion 21 exceeds the limiting surface 111. The first protruding part 21 can be clamped with the key body 1, so that the axial direction of the bolt 2 is limited.
In a preferred embodiment, the first protrusion 21 is wedge-shaped, and the key body 1 has a mating slope surface that mates with the first protrusion 21. The first projection 21, being wedge-shaped, facilitates the extraction of the bolt 2 by the user. Moreover, the design can be adopted, when the key body 1 is at the second position, the first protruding part 21 exceeds the limiting surface 111, the bolt 2 is forced to be pulled outwards, and because the first protruding part 21 is clamped with the key body 1 through a wedge, the part of the bolt 2 close to the first protruding part 21 can be elastically deformed along the wedge, so that the bolt 2 can be pulled out; if the bolt 2 is not applied with force, the bolt 2 cannot slide out by itself. Therefore, the bolt 2 is not easy to fall off in the use process of the mobile terminal, and the bolt 2 is still convenient to disassemble.
The bolt 2 further comprises a second protruding portion 22, the first protruding portion 21 and the second protruding portion 22 are arranged at intervals along the length direction of the bolt 2, and the limiting surface 111 is located between the first protruding portion 21 and the second protruding portion 22. The second boss 22 prevents the plug pin 2 from being inserted too much, and prevents the plug pin 2 from falling into the housing 3 and becoming unable to be removed, that is, the first boss 21 and the second boss 22 together restrict the position of the plug pin 2 in the axial direction thereof.
One end portion of the plug 2 is provided with a coupling groove 23, and the coupling groove 23 has a first wall surface 231 facing the other end portion of the plug 2. The first wall 231 can be used as a force application position for pulling the plug 2 outward, and a user can hook the first wall 231 by using a tool (such as tweezers) to pull the plug 2 out, so that the user can detach the plug 2 more conveniently. In the present embodiment, the first protruding portion 21 and the connecting groove 23 are respectively located at both ends of the plug 2.
As shown in fig. 2 and 3, the key body 1 is provided with a pressing column 7, and the pressing column 7 extends in the second direction. The end part of the pressing column 7 can be abutted against the snap dome 4, and the snap dome 4 can be touched by pressing the key body 1, so that a key signal is sent. And the pressing post 7 may be engaged with the guide hole 33 of the housing 3 so that the key body 1 can move only in the first and second directions.
As shown in fig. 7, the pressing column 7 is sleeved with a sealing member 5, and the sealing member 5 is configured to enable the pressing column 7 to be sealed with the housing 3 of the mobile terminal, in this embodiment, the sealing member 5 is an annular silicone sealing ring and can be connected with the pressing column 7 through an in-mold injection molding process. The sealing member 5 seals the pressing post 7 from the guide hole 33 of the housing 3, preventing external dust, rainwater, etc. from entering the inside of the housing 3.
The two ends of the key body 1 in the length direction are provided with a pressing column 7 and a bolt 2. The key body 1 is in a strip shape, and two end portions in the length direction of the key body 1 are respectively provided with a pressing column 7, so that the key body 1 is provided with two key positions (for example, the key assembly is a volume key, and the two key positions are respectively used for increasing volume and reducing volume), and in order to avoid the height unevenness of the two ends of the key body 1, the two ends of the key body 1 are respectively provided with a bolt 2.
The key body 1 may also be provided with a sealing member 5 (for example, the sealing member 5 is disposed between the key body 1 and the housing 3), and the sealing member 5 is configured to seal the key body 1 and the housing 3 of the mobile terminal, so as to prevent external impurities from entering the housing 3.
The key assembly further comprises an elastic member 6, and the elastic member 6 is used for providing the elastic force required by the key body 1 to move towards the first position. When the key body 1 is driven by external force to move from the first position to the second position, the elastic member 6 is compressed, and after the external force is removed, the elastic member 6 can push the key body 1 to move to the first position. And the elastic member 6 can overcome the problem that the key body 1 is difficult to rebound to the first position due to the sealing member 5. As shown in fig. 7, the housing 3 is provided with a receiving groove 32, the key body 1 is at least partially disposed in the receiving groove 32, and two ends of the elastic element 6 respectively abut against the bottom of the housing 3 and the receiving groove 32.
While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
