[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the following is a further detailed description of the present invention's capacitive touch mobile phone case with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention.

[0021] In the description of the present invention, unless otherwise specified, "plurality" means two or more; the terms "center", "longitudinal", "lateral", "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0023] See Figures 1 to 6 The mobile phone case for capacitive touch of a mobile phone according to an embodiment of the present invention includes a shell 1, the shell 1 is provided with a retaining groove 15 for placing the mobile phone, a touch button 2 is embedded on one side of the shell 1, and the touch button 2 corresponds to the position of the capacitive touch key on the mobile phone. A plurality of contacts 21 are evenly distributed on the side of the touch button 2 corresponding to the mobile phone, and the contacts 21 are separated from each other.

[0024] In the above embodiment, by embedding a touch button 2 at a specific position of the mobile phone case (i.e., the area corresponding to the capacitive touch button of the mobile phone), and evenly distributing multiple tiny and independently separated contact points 21 on the contact surface of the button, seamless docking and enhancement of the original touch experience of the mobile phone is achieved.

[0025] Specifically, these contacts 21 act as physical contact points. When a user presses a touch button 2, based on the principle of force distribution, only the portion of the contacts 21 directly applying force will move slightly forward, simulating the precise pressing motion of a human finger. This process, due to the independence and miniaturization of the contacts 21, ensures that even a light touch accurately transmits the press signal to the capacitive touch sensor on the bottom layer of the phone.

[0026] Furthermore, the capacitive touch sensor can sensitively detect static electricity changes caused by these contacts 21, converting them into electronic signals for processing, thereby triggering the corresponding functions or operations of the phone. This design not only retains the original touch sensitivity and accuracy of the phone, but also overcomes the touch barriers that may be caused by phone cases through innovative physical structures, providing users with a more convenient and accurate operation experience.

[0027] See Figures 1 to 6 In another embodiment, a seating groove 19 is provided on one side of the shell 1, and the middle part of the inner wall of the seating groove 19 extends inward to form a limiting edge 191, and a limiting groove 22 matching the limiting edge 191 is provided on the side of the touch button 2.

[0028] In the above embodiment, the physical limiting and interlocking ensure that the touch button 2 can be firmly fixed in the mounting groove 19 after installation and is not prone to shaking or falling off.

[0029] At the same time, the close connection between the limiting edge 191 and the limiting groove 22 also provides a good positioning effect, allowing the touch button 2 to accurately align with the capacitive touch key position on the mobile phone, ensuring touch accuracy. This structural design not only enhances the durability of the mobile phone case, but also improves the user experience.

[0030] See Figures 1 to 6 In another embodiment, a charging port 16 is provided at the bottom of the housing 1 , and a charging cover 17 is provided, and the charging cover 17 covers the charging port 16 .

[0031] In the above embodiment, a charging port 16 is specially provided at the bottom of the housing 1, so that the user can conveniently perform charging operations while the mobile phone case covers the mobile phone without having to frequently remove the mobile phone case.

[0032] Charging cover 17 closes over charging port 16, forming a physical barrier. The principle behind this design is that closing charging cover 17 effectively prevents dust, moisture, and other foreign matter from entering charging port 16, thereby keeping the phone's charging port clean and intact, and preventing charging malfunctions or damage caused by foreign matter. Closing methods include, but are not limited to, magnetic and snap-on styles.

[0033] See Figures 1 to 6 In another embodiment, a sound hole 18 is further provided at the bottom of the housing 1 to maintain the normal use of the mobile phone speaker function.

[0034] See Figures 1 to 6In another embodiment, the shell 1 includes an upper shell 11 and a lower shell 12. The upper shell 11 extends inward and is inclined to have a card edge. The card edge is used to limit the mobile phone. The upper shell 11 and the lower shell 12 are threadedly connected, and a sealing rubber ring is provided at the connection between the upper shell 11 and the lower shell 12.

[0035] In the above embodiment, the extended and inclined retaining edge inside the upper shell 11 is used to precisely limit and secure the phone. By physically engaging the phone, the retaining edge secures the phone in place after installation inside the shell, preventing it from accidentally falling off during daily use.

[0036] Secondly, the upper shell 11 and the lower shell 12 are connected by a threaded connection, which is not only structurally stable but also easy to disassemble and install. The upper shell 11 and the lower shell 12 can be disassembled, and the mobile phone can be placed in the lower shell 12. The upper shell 11 is then fixed to the lower shell 12, so that the mobile phone can be placed in the housing 1.

[0037] Finally, a sealing rubber ring is carefully arranged at the connection between the upper shell 11 and the lower shell 12. The main function of the sealing rubber ring is to enhance the sealing performance of the mobile phone case, prevent dust, moisture and other external debris from entering the interior of the mobile phone, thereby protecting the mobile phone from damage.

[0038] See Figures 1 to 7 In another embodiment, the number of the contacts 21 is at least two.

[0039] See Figures 1 to 6 In another embodiment, the contact 21 is made of conductive material.

[0040] In the above embodiment, the conductive material has good electrical conductivity. When it comes into contact with the capacitive touch screen of the mobile phone, it can effectively transmit electrostatic signals, simulating the effect of a finger touch. This property ensures that the user can achieve precise control through the touch button 2 even when the phone is covered by a case.

[0041] Secondly, the conductive material is soft and elastic. The softness allows the contact 21 to better conform to the curved surface of the phone's touch screen, reducing gaps and improving touch sensitivity. The elasticity ensures that during the pressing process, the contact 21 can undergo slight deformation and return to its original shape, simulating the natural process of finger pressing.

[0042] See Figures 1 to 6 In another embodiment, a camera module adapter hole 13 is provided on the back of the lower shell 12, and a protective frame 14 is provided around the camera adapter hole. When the camera module of the mobile phone is placed in the camera module adapter hole 13, the thickness of the protective frame 14 is greater than the camera module.

[0043] In the above embodiment, since modern mobile phone camera modules generally adopt a protruding design, this feature makes the camera relatively fragile in the overall structure of the mobile phone and easily damaged in accidental situations such as falling.

[0044] Therefore, the thickness of the protective frame 14 is set to be greater than that of the camera module. When the phone's camera is dropped vertically, the protective frame 14 will first contact the ground, bearing the primary impact force, effectively mitigating or even preventing direct impact on the camera module. This "buffer zone" not only protects the camera module from physical damage but also maintains the camera's performance and the phone's overall aesthetics.

[0045] In addition, the thickened design of the protective frame 14 also enhances the overall stability of the mobile phone case, so that when the mobile phone is held, the fingers can press against the edge of the protective frame 14, making the grip more stable.

[0046] See Figure 6 as well as Figure 7 , Figure 6 is a schematic diagram of a protruding contact point. Figure 7 This is a schematic diagram showing that the contacts do not protrude.

[0047] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of the technical content disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
