Abstract
Description
Technical Field
[0001] The utility model relates to a protective case for a mobile intelligent device. Background Art
[0002] In current mobile intelligent devices, such as mobile phones, tablets, etc., touch keys are usually provided on their sides. By touching the touch keys, some controls of the mobile intelligent device can be realized, such as waking up, adjusting the volume, and so on. Generally, the protective cases of existing mobile intelligent devices are provided with openings for exposing the touch keys, so as to expose the touch keys for the user to touch and operate conveniently. However, such openings will affect the waterproof performance of the protective case. If the mobile phone protective case is not provided with openings and completely covers the touch keys, it will affect the user's touch operation. Therefore, the applicant is researching and developing a connector capable of conducting touch operations. When disposed on the protective case, it can cover the touch keys and operate the touch keys normally. Pressing the connector can make the connector move slightly to press the touch keys. At present, a problem encountered in the research and development process is that the structure of the protective case for clamping and fixing the connector is relatively rigid, and a relatively large pressing force is required to achieve the effect of pressing the touch keys, which affects the feel.

[0025] Protective case 100, housings 1, 1', side edges 11, holding holes 12, 12', edges 121, 121', notches 122, grooves 122', tactile connector 2, outer shell 21, top wall 211, side walls 212, receiving cavity 213, opening 214, holding groove 215, conduction module 22, substrate 221, upper conductive sheet 222, lower conductive sheet 223, via hole 224, double-sided tape 23. Detailed implementation manners
[0026] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are merely examples of devices, systems, equipment, and methods consistent with some aspects of the present invention.
[0027] Referring to Figure 1 the figure shown, the protective case 100 of the present invention is used to protect a smart mobile device, which can be a mobile phone case or a Pad case. Hereinafter, the mobile phone case 100 will be taken as an example for description. The protective case 100 is wrapped around a mobile phone (not shown), and the protective case 100 includes a housing 1 and a tactile connector 2 provided on the side edge 11 of the housing 1.
[0028] Referring to Figures 2 to 4 the figure shown, the tactile connector 2 is generally in the shape of a strip and includes an outer shell 21, a conduction module 22, and a double-sided tape 23 for fixing the conduction module 22 inside the outer shell 21. The outer shell 21 is provided with a top wall 211 and a circle of side walls 212. The top wall 211 and the side walls 212 together enclose a receiving cavity 213, and an opening 214 is formed on the bottom side of the outer shell 21 for the receiving cavity 213. The conduction module 22 is assembled into the receiving cavity 213 from the opening 214, and the top surface of the conduction module 22 faces the top wall 211. The double-sided tape 23 is disposed between the top wall 211 of the outer shell 21 and the conduction module 22, and bonds the bottom surface of the top wall 211 and the top surface of the conduction module 22 to fix the conduction module 22 in the receiving cavity 213.
[0029] The conduction module 22 is a PCB board, including a substrate 221, a plurality of upper conductive sheets 222 arranged on the upper surface of the substrate 221, a plurality of lower conductive sheets 223 arranged on the lower surface of the substrate 221, and a plurality of vias 224. The upper conductive sheets 222 and the lower conductive sheets 223 are arranged one by one in the upper and lower directions, and the vias 224 penetrate the upper conductive sheets 222, the substrate 221, and the corresponding lower conductive sheets 223 to electrically conduct the upper conductive sheets 222 and the lower conductive sheets 223 arranged in the upper and lower directions. During manufacturing, gold is plated on the upper surface, the lower surface, and the inner wall of the vias 224 of the PCB board by electroplating to form a gold plating layer, namely, the upper conductive sheets 222 and the lower conductive sheets 223 that are conductive to each other. The double-sided adhesive 23 covering the top surface of the conduction module 22 can completely cover the upper conductive sheet 222. The conduction module 22 is in the form of a PCB board, which is smaller in size and can reduce the cost of the product.
[0030] Combination Figure 1 , Figures 5 to 6 As shown, the side edge 11 of the housing 1 is provided with a holding hole 12, and the holding hole 12 is arranged corresponding to the touch key (not shown) on the side of the mobile phone (not shown), and the side wall 212 of the touch connector 2 is provided with a circle of holding grooves 215 along its circumference, and the touch connector 2 is inserted into the holding hole 12, and the holding hole 12 is provided with a circle of edges 121 that are inserted into the holding groove 215, so that the touch connector 2 can be fixed on the housing 1. The touch connector 2 can cover the touch key (not shown) of the mobile phone (not shown), and the lower conductive sheet 223 of the touch connector 2 is electrically connected with the touch key (not shown) of the mobile phone (not shown), and this electrical connection includes the way of electrical connection through a thin double-sided tape (not shown).
[0031] When the protective case 100 is used with a mobile phone (not shown), since the top wall 211 of the shell 21 is relatively thin, it does not affect the conduction of static electricity. The double-sided adhesive tape 23 is also relatively thin and does not affect the conduction of static electricity. The sliding of the user's finger on the top wall 211 of the shell 21 can be transmitted to the multiple upper conductive sheets 222, and further transmitted to the multiple lower conductive sheets 223, so that the multiple lower conductive sheets 223 are intermittently connected. The lower conductive sheets 223 are electrically connected to the touch keys (not shown) on the mobile phone (not shown), so that a tactile effect of sliding contact is generated on the surface of the touch keys (not shown). According to the functional definition of the touch keys (not shown) themselves, control effects such as the effect of zooming in or out the screen, or the effect of flipping up or down the screen page, can be generated. And the user's touch operation is transmitted to the touch keys (not shown)
[0032] The upper conductive sheet 222, the lower conductive sheet 223, and the via 224 that are vertically aligned are collectively referred to as a conductor. The specific form of the conductor is not limited. In this embodiment, it is a conductive sheet that is electrically conductive, and other forms can also be used, such as conductive terminals (not shown), conductive posts, which can be separate or integral. The conductor exposes upwards from the conduction module 22 and is electrically connected to the human body through the double-sided tape 23 and the housing 21. The conductor exposes downwards from the conduction module 22 and is electrically connected to the touch key (not shown). A plurality of conductors are distributed along the longitudinal direction of the touch connector 2. The number and shape of the conductors can be adjusted, but there are at least two to identify the sliding touch and gap conduction.
[0033] Continuing to refer to Figure 5 and Figure 6 As shown, the thickness of the edge 121 of the holding hole 12 is less than the depth of the holding hole 12, and the edge 121 is made of a soft material and can elastically deform and snap into the holding groove 215. The holding hole 12 is in a strip shape with semi-circular ends at both ends. The edge 121 is provided with a plurality of through notches 122 along its circumferential direction. The notches 122 are located at the free ends of the edge 121 and are semi-circular with a radius of 0.5 mm. In this embodiment, the edge 121 is provided with 6 notches 122, which are respectively located at the four corners and the center of the long side. The number of notches 122 can be 4 or more, and they can be arranged at intervals. Preferably, they are arranged at the corners. The user presses the touch connector 2 to drive the touch connector 2 to move slightly inward to achieve the pressing operation on the touch key (not shown) of the mobile phone (not shown). The setting of the notches 122 can reduce the strength of the edge 121, making the pressing force required for the pressing operation smaller and the feel better.
[0034] Refer to Figure 7 and Figure 8 As shown, the present invention also provides another alternative embodiment of the housing, the housing 1'. The difference between the housing 1' and the housing 1 is only that there is no notch, and instead, debonding is performed at the root of the edge 121' of the holding hole 12' to form a groove 122'. Similarly, the strength of the edge 121' can be reduced, making the pressing force required for the pressing operation smaller and the feel better. Specifically, the groove 122' is arranged in a full circle along the circumferential direction on the inner side surface of the edge 121'. The width of the groove 122' is 0.2 mm, and the depth is 0.15 mm. Other structures of the housing 1' can refer to the relevant description of the housing 1.
[0035] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of protection of the present invention.
