[0025] In the following description, suffixes such as "module", "component", "assembly" or "unit" are used only to facilitate the description of the present invention and have no specific meanings. Therefore, they can be used in combination.

[0026] The present invention will be further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0027] The electronic device targeted by the present invention is an electronic device with a side touch panel, such as Figure 5 As shown, the side touch panel is usually a capacitive touch panel. When the user's finger touches the touch panel, the capacitor discharges and then converts the touch signal into an electrical signal. The surface of this type of touch panel is arranged with a number of independent sensing units. If the side touch panel is directly covered with a conductive metal, all the sensing units will be interconnected, and the sliding operation of the finger cannot be recognized; if the side touch panel is directly exposed, it is impossible to provide all-round waterproof protection for this type of electronic device.

[0028] According to one embodiment of the present invention, Figure 1 and Figure 2 As shown, a method for manufacturing an electronic device protective shell comprises the following steps: S1. A base of the touch key board 1 is formed by injection molding, wherein a plurality of mutually independent recessed portions are formed on the upper and lower surfaces of the base, and the recessed portions on the upper surface are connected with the recessed portions on the lower surface through a channel inside the base; S2, pouring liquid conductive material into the substrate and condensing it to form a plurality of conductive units that penetrate the upper and lower surfaces of the substrate and are independent of each other on the substrate, thereby forming a touch key panel 1; S3, placing the touch key panel 1 into an injection mold for injection molding, and releasing the injection mold to obtain an electronic device protective shell.

[0029] In this embodiment, a plurality of conductive units that penetrate the upper and lower surfaces of the substrate and are independent of each other are formed on the substrate by pouring liquid conductive material into the substrate and condensing it. Different from a whole piece of conductive metal directly covering the side touch panel 6, the touch key panel 1 formed by the steps of this embodiment includes a plurality of independent conductive units. When a finger touches one of the conductive units, the sensing unit on the touch panel corresponding to the conductive unit can recognize the touch signal. When the finger slides on the plurality of conductive units in turn, the sliding operation of the finger can be recognized.

[0030] Furthermore, in this embodiment, the formed touch key panel 1 is combined with the frame of the electronic device protective shell by injection molding, so that the formed electronic device protective shell can completely wrap the electronic device while ensuring the normal use of the side touch panel 6 function.

[0031] In this embodiment, the conductive material poured into the matrix can be conductive silicone. The conductive silicone achieves good conductivity by adding conductive fillers (such as acetylene black, carbon fiber, copper powder, silver powder, etc.), and has low volume resistivity, resistance to high and low temperatures (-70 to 200°C), aging resistance, and good processing and manufacturing performance.

[0032] In addition, in this embodiment, the conductive material poured into the substrate can also be a conductive metal material, such as copper. Liquid copper is dripped into the substrate and condensed to form multiple independent conductive units on the substrate. It should be noted that in addition to copper, other conductive metals can also be used, such as aluminum, iron, etc.

[0033] According to an embodiment of the present invention, step S3, placing the touch key panel 1 into an injection mold for injection molding, and releasing the injection mold to obtain an electronic device protective shell, comprises: Put the touch key panel 1 into an injection mold and perform injection molding using TPU material or ABS material as the injection material; The injection mold is released to obtain an electronic device protective shell with a touch key panel 1.

[0034] In this embodiment, the base material is PC material. After plasticization, ABS material and TPU material can be fully fused with PC material, and can be tightly and evenly combined with it to form a tight wrapping for the touch key board 1 to ensure the sealing of the edge of the touch key board 1.

[0035] According to one embodiment of the present invention, a method for manufacturing a protective shell of an electronic device is provided. Figures 1 to 4 As shown, the following steps are included: S1. A base of the touch key board 1 is formed by injection molding, wherein a plurality of mutually independent recessed portions are formed on the upper and lower surfaces of the base, and the recessed portions on the upper surface are connected with the recessed portions on the lower surface through a channel inside the base; S2, pouring liquid conductive material into the substrate and condensing it to form a plurality of conductive units that penetrate the upper and lower surfaces of the substrate and are independent of each other on the substrate, thereby forming a touch key panel 1; S3, placing the touch key panel 1 into an injection mold for injection molding, and releasing the injection mold to obtain an electronic device protective shell.

[0036] Wherein, S3, placing the touch key panel 1 into an injection mold for injection molding, and releasing the injection mold to obtain an electronic device protective shell, comprising: Injection molding is performed using PC material as the injection molding material to obtain a protective shell middle frame 2; Put the touch key panel 1 and the protective shell middle frame 2 into an outer frame injection mold, and perform injection molding using TPU material or ABS material as the injection material to form a protective shell outer frame 3 wrapped around the outer side of the protective shell middle frame 2 and having the touch key panel 1; The outer frame injection mold is released to obtain an electronic device protective case.

[0037] In this embodiment, Figure 3 and Figure 4 As shown, the protective case middle frame 2 is obtained by injection molding with PC material as the injection molding material. The PC material can be fully fused with the ABS material and the TPU material after plasticization. The formed electronic device protective case has a PC material middle frame and a TPU material or ABS material outer frame. The PC material protective case middle frame 2 has a strong hardness, while the TPU material or ABS material outer frame has good elasticity and sealing.

[0038] Furthermore, the protective shell frame 3 is preferably formed by injection molding with TPU material, which has excellent wear resistance and can effectively resist the friction and scratches of the protective shell frame 3 in daily life.

[0039] Further, in this embodiment, if Figure 3 and Figure 4As shown, a charging port plug 4 is formed on the protective shell frame 3, and the charging port plug 4 is movably connected to the protective shell frame 3. By forming the charging port plug 4 on the protective shell frame 3 by injection molding, in an environment where wading is possible, the charging port of the electronic device is blocked by the charging port plug 4 to prevent water from entering the charging port, thereby further improving the waterproof performance of the electronic device protection.

[0040] Further, in this embodiment, if Figure 3 and Figure 4 As shown, the protective shell middle frame 2 is provided with a button hole, the protective shell outer frame 3 is formed with a button cap 5 by injection molding, and the button cap 5 is closed connected with the protective shell outer frame 3. In this embodiment, the button cap 5 formed by injection molding can wrap the button of the electronic device without affecting the normal use of the button. The button cap 5 is closed connected with the protective shell outer frame 3, which can effectively prevent water from entering the button when it is used in water.

[0041] It should be noted that there can be more than one button cap 5 , depending on the number of buttons of the electronic device.

[0042] Further, such as Figure 2 As shown, the multiple conductive units on the touch keypad 1 are arranged in a longitudinal direction. By arranging the multiple conductive units in a longitudinal direction, the signal of the finger sliding in the longitudinal direction can be accurately identified, which is in line with the operation logic of the front touch panel 6.

[0043] It should be noted that if the size of the conductive unit can be made smaller, a plurality of conductive units arranged in two vertical rows can be formed, or even more.

[0044] In the description of the specification, the description with reference to the terms "one embodiment", "some embodiments", "an embodiment", "some embodiments", "an example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.
