[0024] The technical solutions in the embodiments of this utility model will now be described with reference to the accompanying drawings.
[0025] Please see Figure 1 This utility model provides a protective case 100, specifically, the protective case 100 is adapted to electronic products such as mobile phones and tablets.
[0026] Please see Figures 1 to 4 The protective shell 100 includes a shell 10 and a button function module 40; the button function module 40 is disposed inside the shell 10 and is formed into a one-piece integral with the shell 10.
[0027] Specifically, the button function module 40 includes a first part and a second part. Please refer to [link / reference]. Figure 4 In this embodiment, the button function module 40 is specifically an integrated board with NFC sensing and an operation panel. The first part of the button function module 40 includes a switch module 41 responsible for providing operating components such as switch buttons; the second part of the button function module 40 includes an FPC coil 44 responsible for NFC sensing and signal transmission. The FPC coil 44 and the switch module 41 are electrically connected by a switch circuit 43, forming a whole. That is, the button function module 40 includes a switch module 41 and an FPC coil 44. The switch module 41 includes a switch circuit 43 and a button 42.
[0028] Please see Figure 1 and Figure 2 In this embodiment, the housing 10 is made of at least two layers of synthetic fiber fabric molded under high temperature and pressure. The button function module 40 is placed between the two layers of synthetic fiber fabric. The switch module 41 is at least partially exposed from the housing 10. Under high temperature and pressure, the filler inside the synthetic fiber fabric melts and flows until it partially contacts the switch module 41. After the filler cools and solidifies, it forms the housing 10 and is fixedly connected to the button function module 40 as a whole. The FPC coil 44 is fixed inside the housing 10, while the button 42 of the switch module 41 protrudes from the housing 10. Understandably, the button 42 of the switch module 21 protrudes from the outer surface of the housing 10.
[0029] Please see Figure 1 , Figure 3 and Figure 4 To prevent the filler in the housing 10 from interfering with the normal function of the button 42 exposed on the switch module 21, in this embodiment, the protective housing 100 is further provided with a protective member 50 fixedly connected to the switch module 41. Preferably, the protective member 50 has a button hole 52. The button 42 of the switch module 41 is exposed through the button hole 52.
[0030] Please see Figure 4 Specifically, the button 42 includes a keycap 45 and an outer edge 46 fixed below the keycap 45, the outer edge 46 contacting the switch circuit. The protective member 50 is a single piece. In this embodiment, the protective member 50 is provided with a receiving groove 55 for accommodating the outer edge 46. The keycap 45 is exposed from the key hole 52; the outer edge 46 contacts the switch circuit 43. Preferably, the position of the key hole 52 corresponds to the middle area of the receiving groove 55; the outer edge 46 is limited by the hole wall of the key hole 52. In this way, pressing the keycap 45 allows the entire button 42 to be pressed down smoothly, ensuring the normal use of the button function module 40. In an alternative embodiment, the receiving groove 55 can also be provided to the switch module 41. For example, the receiving groove 55 and the button 42 form a single piece.
[0031] Please see Figures 1 to 4 In this embodiment, the switch module 41 comprises at least two buttons 42 disposed on a switch circuit 43; the protective component 50 is fixedly connected to a switch circuit 43. Specifically, the protective component 50 is fixedly connected to the switch circuit 43 in one of the following ways: adhesive bonding, fusion welding, welding, or snap-fit connection.
[0032] Specifically, the protective member 50 has the same number of button holes 52 as the number of buttons 42. The protective member 50 also has the same number of receiving slots 55 for accommodating the outer edge 46 of the buttons 42 as the number of buttons 42.
[0033] Further, please refer to Figure 2 The housing 10 has an opening 13. The switch module 41 is disposed inside the housing 10 and is fixedly connected to the wall of the opening 13 inside the housing 10. The protective member 50 covers the opening end of the opening 13 inside the housing 10. In this way, while achieving a fixed connection between the housing 10 and the switch module 41, it is ensured that the protective member 50 can effectively protect the switch module 41. In other solutions, the switch module 41 is fixedly connected to the housing 10 by being embedded inside the housing 10.
[0034] In this embodiment, the opening 13 is a blind slot. The switch module 41 is disposed at the bottom of the blind slot; and the protective member 50 is disposed in the blind slot.
[0035] Preferably, the button 42 exposes the open end of the blind groove; and the height of the button 42 is greater than the depth of the blind groove. In this way, the button 42 protrudes from the outer surface of the protective member 50 and the housing 10, making it easier to press the button 42.
[0036] It should be noted that the button type of button 42 includes, but is not limited to, dome buttons. In high-temperature and high-pressure environments, a high-temperature resistant removable part can be provided to cover the button hole 52 to prevent molten filler from overflowing the receiving groove 55 and flowing from the button hole 52 into the switch module 41.
[0037] Please see Figure 2 and Figure 4 The housing 10 includes a main cover plate 11 and a frame 12 extending from the main cover plate 11, the frame 12 having an opening 13. A second portion of the button function module 40 is fixed to the main cover plate 11; a first portion of the button function module 40 is disposed on the frame 12. In this embodiment, the FPC coil 44 serves as the second portion of the button function module 40 and is fixed to the main cover plate. The switch module 41 serves as the first portion of the button function module 40 and is disposed on the frame 12, with at least a portion of the switch module 41 exposed through the opening in the frame of the housing 10.
[0038] Please see Figure 5 In another embodiment, the difference from this embodiment is that the switch module 41 has a button 42. That is, the protective shell 100 can be provided with a plurality of switch modules 41, each switch module 41 having a button 42 and a switch circuit. Each protective member 50 is fixedly connected to the surface of the switch circuit in the area of a corresponding button 42. The protective member 50 is fixedly connected to the surface of the switch circuit 43 in one of the following ways: adhesive bonding, fusion welding, soldering, or snap-fit connection. Specifically, the number of protective members 50 is the same as the number of switch modules 41. Please refer to... Figure 6 For each protective component 50, the corresponding switch module 41 only needs to be provided with one button hole 52 and one receiving slot 55.
[0039] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
