Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the 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 application.
As shown in fig. 1 to 4, the side key waterproof device 200 of the present application is used in a mobile terminal 100, and the mobile terminal 100 may be a mobile phone or a tablet computer. The side key waterproof device 200 includes an elastic body 2 fixed on the housing 1 of the mobile terminal 100, a side key 3 fixed on the elastic body 2, and a sealing body 4 for sealing between the elastic body 2 and the housing 1. The sealing body 4 seals the elastic body 2 and the housing 1, so that the mobile terminal 100 is sealed at the installation position of the side key waterproof device 200, and the waterproof and dustproof effects of the mobile terminal 100 are improved.
The side key 3, the elastic body 2, and the sealing body 4 may be provided in various manners, and the manner of providing the side key 3, the elastic body 2, and the sealing body 4 will be described in detail below by taking various examples as examples.
Example one
Since the side key 3 is generally rectangular parallelepiped, the structure of the side key 3 and the elastic body 2 will be described below based on the rectangular parallelepiped side key 3.
The side key 3 includes an annular side wall 31, and an end cap 32 provided at one end of the annular side wall 31. Thus, the structure of the side key 3 can be simplified, the processing and manufacturing cost can be reduced, and the side key 3 can be conveniently adhered to the elastic body 2 through the adhesive. The junction of the annular sidewall 31 and the end cap 32 may be rounded or beveled to reduce the likelihood of a user scratching the junction of the annular sidewall 31 and the end cap 32. The annular sidewall 31 and the end cap 32 may be integrally formed to facilitate manufacturing.
The main body of the elastic body 2 has a substantially plate-like structure and a substantially rectangular shape. The material of the elastomer 2 may be TPU (Thermoplastic polyurethane elastomers). The elastic body 2 is divided into two regions. One area is a side key area 21 provided in the middle and having a substantially rectangular shape, and the side key area 21 is used for mounting the side keys 3. The other area is an extension area 22, which is located at the periphery of the side keypad 21, surrounding the side keypad 21. When the side key waterproof device 200 is mounted on the mobile terminal 100, the side key region 21 is located at the side key mounting hole of the housing 1, and the extension region 22 is attached to the inner wall of the housing 1 and surrounds the side key mounting hole of the housing 1.
The extension 22 may be secured to the inner wall of the housing 1 by adhesive for ease of placement. The sealing body 4 may be an adhesive, in other words, the extension areas 22 surrounding the side key areas 21 are all provided with an adhesive, when the extension areas 22 are adhered to the inner wall of the casing 1, the sealing between the extension areas 22 and the casing 1 is realized through the adhesive, so that the sealing between the side key waterproof device 200 and the casing 1 is realized. Through the arrangement of the mode, the structure is simple, and the cost is low.
The width (direction from the side key region 21 to the boundary of the elastic body 2) and the thickness (direction perpendicular to the elastic body 2) of the extension region 22 can be specifically set as required. The thickness of the adhesive can also be specifically set as required. In one example, since the stroke of the side key 3 is generally between 0.1-0.2mm, and in view of reducing the space occupied by the side key waterproof device 200 in the housing 1, the width of the extension 22 may be approximately between 0.2-0.4mm, the thickness of the extension 22 may be approximately between 0.1-0.15mm, and the thickness of the adhesive may be approximately between 0.05-0.1 mm.
The side key region 21 may have a cross-sectional area larger than that of the side key installation hole. In general, the cross-sectional area of the side key 3 is smaller than that of the side key mounting hole, and therefore, the cross-sectional area of the side key region 21 may be larger than that of the side key mounting hole, in other words, when the side key 3 is mounted in the side key region 21, a gap is left between the side key 3 and the extension region 22. Therefore, when the side key 3 is pressed, the resistance of the viscose to the deformation of the elastic body 2 can be reduced, and the user experience is improved; and damage to the adhesive can be reduced, thereby reducing the possibility of the elastic body 2 being detached from the housing 1.
The thickness of the side keypad 21 may be smaller than that of the extension area 22 and the front surface (the side where the side keys 3 are disposed) of the side keypad 21 is recessed. When the thickness of the side key region 21 is smaller than that of the extension region 22, the deformation degree of the side key region 21 can be increased, and the deformation degree of the extension region 22 can be reduced, so that the possibility that the elastic body 2 is separated from the housing 1 can be further reduced. The front surface of the side keypad 21 is concave, so that the possibility that the side keypad 21 is adhered to the housing 1 by glue can be reduced. The back surface (the side opposite to the front surface) of the side key region 21 may be flush with the back surface of the extension region 22 to facilitate processing of the elastic body 2. The thickness of the side keypad 21 can be specifically set according to the requirement. In one example, the side keypad 21 has a thickness between 0.05-0.07 mm.
In addition, as shown in fig. 5, the elastic body 2 may further include a boss 23 disposed at the rear of the side key region 21 to facilitate contact with the side key switch 5 of the mobile terminal 100. In order to reduce the feeling of thickness when the side key 3 is pressed and improve the comfort when the side key 3 is pressed, the boss 23 is located within a range surrounded by the annular side wall 31, in other words, the cross-sectional area of the boss 23 is smaller than the cross-sectional area of the annular side wall 31, and the outer edge of the boss 23 does not exceed the edge of the annular side wall 31 in the direction perpendicular to the axis of the annular side wall 31.
Further, as shown in fig. 6, a sealing ring 24 surrounding the side keys 3 may be provided on the front surface of the side key region 21. When the side key waterproof device 200 is installed in the mobile terminal 100, the sealing ring 24 extends to a gap position between the side key 3 and the inner wall of the housing 1 to reduce the possibility that liquid such as water enters the concave position of the side key region 21, thereby reducing the possibility that the viscose is soaked by water and loses efficacy.
Example two
The difference between the second embodiment and the first embodiment is that the annular pressure plate for pressing the extension area is arranged on the inner wall of the shell, and the installation firmness of the annular pressure plate is high. When the elastic body is installed, the extension area is plugged under the annular pressure plate, the elastic body is fixed through the annular pressure plate, and sealing between the elastic body and the shell is realized.
EXAMPLE III
The third embodiment is different from the first embodiment in that an annular pressure plate for pressing the extension area is further arranged on the inner wall of the shell. The elastomer sets up on the casing inner wall through the viscose and presses through annular clamp plate and establishes.
In other embodiments, as shown in fig. 7, the projection 23 can also extend beyond the coverage of the annular sidewall 31 of the side key 3 to improve the sensitivity when pressing the side key 3.
In any of the above embodiments, the side key 3 of the side key waterproof device 200 may be a sound key or a power key. In the case of the sound key, the sound increasing key portion and the sound decreasing key portion of the sound key share one elastic body. The elastic body can be provided with two side key regions, one side key region is arranged corresponding to the sound increasing key part, and the other key region is arranged corresponding to the sound reducing key part; a side keypad may also be provided. The elastic body 2 may be provided with two bosses, one boss corresponding to the sound increasing key portion and one boss corresponding to the sound decreasing key portion.
The mobile terminal 100 of the present application includes a case 1 and a side key waterproof device 200 disposed in the case 1. In this mobile terminal 100, the extension region 22 of the elastic body 2 is provided on the inner wall of the housing 1, and the elastic body 2 is sealed by the sealing body 4 provided between the extension region 22 and the housing 1, so that sealing of the mobile terminal 100 at the installation position of the side key waterproof device 200 can be achieved. When the sealing is realized by the elastic body 2 and the sealing body 4, the extension area 22 of the elastic body 2 is positioned on the inner wall of the shell 1, so that a containing groove and the like do not need to be formed on the shell 1, and the structure of the shell 1 can be simplified.
The thickness H (shown in fig. 5) of the elastic body 2 is greater than the distance between the side key switch 5 of the mobile terminal 100 and the case 1. Because the elastic body 2 has elasticity, the key stroke direction can allow a small amount of interference without influencing the side key switch 5, and simultaneously, the hand feeling when the side key 3 is pressed can be increased, and the product yield is increased.
The elastic body can abut against a bracket for arranging the side key switch so as to further improve the fixing firmness of the elastic body.
The above are merely examples of the present application and are not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
