Therefore, the mobile power source 1 of the present embodiment further includes a power supply module 12 and a wireless charging module 13. The power supply module 12 and the wireless charging module 13 are accommodated inside the housing 11. The power supply module 12 includes a printed circuit board 121. The wireless charging module 13 includes an inductive coil 131. The inductive coil 131 is electrically connected to the printed circuit board 121.
The border casing 2 encloses the annular plate 112. An inner circumference of the border casing 2 includes a surrounding block 21 surroundingly disposed around the top plate 111. The surrounding block 21 protrudes beyond the top plate 111, and a gap s is formed between the surrounding block 21 and the top plate 111. The surrounding block 21 consists of silicone, rubber, or other soft materials.
More details are described as follows. The border casing 2 includes a surrounding frame 22. The surrounding block 21 is integrally and extendingly formed from an inner circumference of the surrounding frame 22. The border casing 2 consists of silicone, rubber, or other soft materials, and thereby the surrounding block 21 also consists of silicone, rubber, or other soft materials.
Additionally, an annular block 23 is extendingly formed from the inner circumference of the surrounding frame 22, and an annular groove 24 is formed between the surrounding block 21 and the annular block 23. The protruding annular portion 113 engages with the annular groove 24, so as to make the border casing 2 enclose the annular plate 112.
Moreover, the surrounding block 21 includes a first end 211, the annular block 23 has a second end 231. An interval h1 formed between the first end 211 and a bottom of the annular groove 24 is greater than an interval h2 formed between the second end 231 and the bottom of the annular groove 24. An inner edge of the surrounding block 21 has an inclined surrounding surface 212.
As shown in FIGS. 1 to 4, a combined state of the mobile power device 10 of the present invention utilizes the mobile power source 1. The mobile power source 1 includes the housing 11, and the housing 11 includes the top plate 111 and the annular plate 112. The border casing 2 encloses the annular plate 112. The inner circumference of the border casing 2 includes the surrounding block 21 surroundingly disposed around the top plate 111. The surrounding block 21 protrudes beyond the top plate 111, the gap s is formed between the surrounding block 21 and the top plate 111. Thereby, the surrounding block 21 can restrict a position of the portable electronic product, so that the portable electronic product is securely disposed corresponding to the mobile power source 1, so as to enhance the convenience in using the mobile power device.
FIG. 5 and FIG. 6 show a use state of the mobile power device 10 according to the present invention. First, referring to FIG. 5, when a size of the portable electronic product 100 is smaller than a surface of the mobile power source 1, the portable electronic product 100 can be placed in the gap s and a position of the portable electronic product 100 is restricted by the surrounding block 21, so that the portable electronic product 100 or the mobile power device 10 are prevented from disconnecting or deviating, even if the portable electronic product 100 or the mobile power device 10 undergoes collisions or shaking.
The surrounding block 21 consists of silicone, rubber, or other soft materials, so that the surrounding block 21 can protect the portable electronic product 100 when the surrounding block 21 is surroundingly disposed around the outer circumference of the portable electronic product 100.
Moreover, as shown in FIG. 6, when the size of the portable electronic product 100 is larger than the surface of the mobile power source 1, the portable electronic product 100 is placed on the surrounding block 21 and is pressed in a direction toward the gap s. Since the surrounding block 21 consists of silicone, rubber, or other soft materials, the air in the gap s can be evacuated from around the surrounding block 21, and, in the meanwhile, the surrounding block 21 is sucked to attach to the surface of the portable electronic product 100, so that the gap s is in a vacuum state, and eventually the portable electronic product 100 is sucked to be securely attached to the surrounding block 21, and thereby the mobile power device 10 and the portable electronic product 100 are prevented from disconnecting or deviating when the portable electronic product 100 or the mobile power device 10 undergoes collisions or shaking.
Therefore, under the circumstance that the mobile power source 1 is the wireline mobile power source, it is not easy for the transmission cable to be disconnected from the mobile power device or the portable electronic product when the transmission cable is heavily shaken. Alternatively, under the circumstance that the mobile power source 1 is the wireless mobile power source, it is not easy for the portable electronic product to deviate or be misplaced with respect to the inductive coil. Accordingly, the mobile power device 10 and the portable electronic product 100 are prevented from having ineffective charging or falling to the ground, and thereby enhancing the convenience in using the mobile power device 10 and enhancing charging efficiency.
Furthermore, the surrounding block 21 is integrally and extendingly formed from the inner circumference of the surrounding frame 22, and the border casing 2 consists of silicone, rubber, or other soft materials, and, hence, the air in the gap s can be evacuated from around the border casing 2, so as to enhance the ability of the surrounding block 21 to suck and attach to the portable electronic product 100.
Further, the surrounding block 21 has a first end 211, the annular block 23 has a second end 231. An interval h1 formed between the first end 211 and the bottom of the annular groove 24 is larger than an interval h2 formed between the second end 231 and the bottom of the annular groove 24, so that a contact surface where the surrounding block 21 makes contact with the mobile power source 1 is larger than a contact surface where the annular block 23 makes contact with the mobile power source 1. Therefore the air in the gap s can be easily evacuated out from around the annular block 23, but the air outside is not easy to flow into the gap s from around the surrounding block 21, thereby enhancing the ability of the surrounding block 21 to suck and attach to the portable electronic product 100.
Moreover, an inner edge of the surrounding block 21 has an inclined surrounding surface 212, and the top plate 111 is an arc-shaped protruding plate, and thereby an introducing airflow is formed at one side of the inclined surrounding surface 212 or the top plate 111 and flows to an airflow passageway where the surrounding block 21 closely contacts with the mobile power source 1, so as to introduce the air in the gap s to be evacuated out from around the annular block 23, and, as a result, the surrounding block 21 more easily sucks and attaches to the portable electronic product 100.
In summary, the mobile power device having the border casing according to the present invention certainly can achieve the anticipated objects and improve the defects of the traditional techniques, and completely meet the requirements of patentability, namely industrial applicability, novelty, and non-obviousness. Therefore, a request to patent the present invention is filed according to patent laws. Examination is kindly requested, and allowance of the present application is solicited to protect the rights of the inventor.
