The mobile terminal of this embodiment may be a mobile phone, a mobile tablet, an MP3, an MP4, and the like, for convenience of description, the following description takes the mobile phone as an example, and the design of the side keys in the other terminals can be designed and produced according to the design scheme of this technical scheme.
The side key 40 in the mobile phone generally includes a power key and a volume adjustment key, as shown in fig. 1 to 4 and 7, wherein the side key 40 with a shorter length is the power key and the side key 40 with a longer length is the volume adjustment key, and for simplifying the description, the power key is specifically illustrated.
In this embodiment, the power key has a connection lug 42, the connection lug 42 has a folding hook 420, the side key mounting structure 21 further has a connection cavity 213, the first housing 10 is provided with a fitting protrusion 11, the connection lug 42 is inserted into the connection cavity 213, the fitting protrusion 11 extends into the connection cavity 213, and the fitting protrusion 11 and the folding hook 420 form a stop. In the power key of the present embodiment, the adjusting contact 41 is located in the middle of the power key, and two ends of the power key are respectively provided with one engaging lug 42, correspondingly, two connecting cavities 213 are provided in the side key mounting structure 21 corresponding to the power key, and the folding hook 420 of the engaging lug 42 on the power key extends along the length extension direction of the power key, a stopping position corresponding to the folding hook 420 of one engaging lug 42 is provided on the cavity wall of one connecting cavity 213 in the two connecting cavities 213, and the folding hook 420 of the other engaging lug 42 forms a stopping position with the corresponding matching protrusion 11 on the first housing 10, so that the power key cannot be separated from the side key mounting structure 21.
The side key mounting structure 21 of the present embodiment is further formed with a spring mounting groove 214, the mobile terminal further includes a spring member 60, the spring member 60 is mounted in the spring mounting groove 214, and the power key compresses the spring member 60. Thus, when the power key is at the initial position, even if the user does not press the power key at all, under the action of the compressive elastic force of the spring element 60 (because the pre-tightening force of the spring element 60 installed in the spring installation groove 214 is already in a compressed state), the power key has a tendency to be separated from the side key installation structure 21 outwards, but the power key cannot be separated from the side key installation structure 21 by the cooperation of the engaging protrusion 11 and the stopping of the bent hook 420 of the engaging lug 42, at this time, because the adjusting contact 41 is designed in an umbrella-shaped structure, and the adjusting contact 41 is made of an elastic material of a silicone piece and one end of the adjusting contact 41 is embedded in the side key 40, the adjusting contact 41 passes through the installation through hole on the corresponding cavity wall of the installation cavity 211 and extends into the installation cavity 211, and under the action of the elastic force of the spring element 60, the umbrella-shaped adjusting contact 41 is pressed against the cavity wall around the installation through, thereby forming a sealed and waterproof fit between the conditioning contacts 41 and the chamber walls. In the present embodiment, the power key is assembled using one spring member 60 accordingly. The spring element 60 adopted in this embodiment can select a proper elastic coefficient according to the actual use condition, and a spring which has no influence on the hand feeling of the side key 40 and can support the adjusting contact 41 of the side key 40 to achieve a sealing and waterproof effect needs to be selected.
In the process of assembling the mobile phone, in order to make the sealing assembly between the first housing 10 and the second housing 20 and between the first housing 10 and the side key installation structure 21 more stable and reliable, therefore, the mobile phone of this embodiment further includes an installation sealing member 50, an auxiliary clip member 70 and an auxiliary sealing member 80, the installation sealing member 50 is disposed between the first housing 10 and the second housing 20, and the installation sealing member 50 is attached to the control terminal 31 in a sealing manner, the auxiliary clip member 70 is clipped on the cavity wall of the assembly cavity 211, the auxiliary clip member 70 is disposed between the control terminal 31 and the cavity wall of the assembly cavity 211, and the auxiliary sealing member 80 is disposed between the auxiliary clip member 70 and the control terminal 31 in a sealing manner.
As shown in fig. 7 to 9, the fitting cavity 211 and the connection cavity 213 in the side key mounting structure 21 in the present embodiment are provided in a hermetically sealed manner. In fact, the assembly chamber 211 and the connection chamber 213 are spaced by a chamber wall, and after the assembly of the first housing 10 and the installation sealing member 50 is completed, the assembly chamber 211 and the connection chamber 213 are completely sealed.
In the use process, when the side key 40 of the mobile phone is in the initial position and water enters the side key 40, in order to prevent the water entering the side key mounting structure 21 from entering the assembly cavity 211 to damage the control circuit board 30 and prevent the water from being stored in the side key mounting structure 21 to cause the adjustment contact 41 to be separated from the cavity wall and to lose the seal after the user presses the side key 40, so that the water enters the assembly cavity 211, in the present embodiment, the side key mounting structure 21 is further formed with the receiving groove 212, the side key 40 is located in the receiving groove 212, and the surface of the cavity wall (i.e. the bottom cavity wall) of the connecting cavity 213 away from the first housing 10 and the surface of the groove wall (i.e. the bottom groove wall) of the receiving groove 212 away from the first housing 10 are in the same plane. Thus, water can only enter the connecting cavity 213 and the receiving groove 212 when the side key 40 is in the initial position, and since the bottom cavity wall of the connecting cavity 213 and the bottom groove wall of the receiving groove 212 are at the same level, water can easily overflow from the connecting cavity 213 and the receiving groove 212 without being retained. Therefore, no water enters the fitting cavity 211 even when the user presses the power key.
In the present embodiment, the cavity wall surface of the fitting cavity 211 away from the first housing 10 is in the same plane as the cavity wall surface of the receiving cavity 212 away from the first housing 10. Thus, even if water enters the fitting cavity 211, the water can be made to overflow outward when the power key is in the adjustment position. Alternatively, in order to more effectively prevent water from entering the assembly chamber 211, a chamber wall surface of the assembly chamber 211 away from the first housing 10 (i.e., an assembly chamber bottom chamber wall) may be higher than a chamber wall surface of the receiving groove 212 away from the first housing 10. Thus, as long as the water quantity entering the connecting cavity 213 and the accommodating groove 212 does not exceed the bottom cavity wall of the assembly cavity, water cannot enter the assembly cavity 211, and the adjusting contact 41 in the assembly cavity 211 cannot be damaged by the entering of water.
For the volume adjusting key on the mobile phone, only one connecting lug 42 is arranged, the connecting lug 42 is positioned in the middle of the volume adjusting key, and two volume adjusting contacts 41 are arranged on two sides of the connecting lug 42. During the process of assembling the volume adjustment keys, the coupling lugs 42 of the volume adjustment keys are inserted into the corresponding coupling cavities 213 of the corresponding side key mounting structures 21, and then form stoppers by the corresponding engagement protrusions 11 of the first housing 10 engaging with the folding hooks 420 of the coupling lugs 42 of the volume adjustment keys, thereby preventing the volume adjustment keys from being separated from the side key mounting structures 21. In the present embodiment, the volume adjustment key is assembled using two spring members 60, and the two spring members 60 are symmetrically arranged with respect to the engaging lug 42.
Compared with the prior art, the design method of the side key mounting structure 21 with the side key 40 separated from the side key by the matching protrusion 11 in the embodiment needs to separately additionally design a side key baffle part to buckle the side key, and the side key baffle part is easy to be neglected or not assembled in place in the design structure with the side key baffle part, so that the problems of side key falling or side key poor hand feeling and the like are caused, and the matching protrusion 11 is integrally formed on the first shell 10, so that the problems of neglected installation or not in place assembly can be completely avoided, and the cost is correspondingly saved due to the reduction of one material.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
