Referring to FIGS. 2-3, FIG. 3 is a partial cross-sectional view taken along lines A-A and B-B in FIG. 2. As shown in FIGS. 2-3, a plurality of metal pads 21 (FIG. 2), a recessed portion 22, and a plurality of metal sheets 24 are formed on a surface 203 of the battery module 20, wherein the recessed portion 22 is near to a first side 201 of the battery module 20, and the metal sheets 24 are near to a second side 202 of the battery module 20. It is to be understood that a flexible member 23 (e.g., a plastic or metal sheet) is disposed in the recessed portion 22 of the battery module 20. The flexible member 23 protrudes from the first side 201 of the battery module 20 in a horizontal direction, and protrudes from the surface 203 upwardly in a vertical direction.
As shown in FIG. 3, a notch 123 is formed on the top portion 121 of the housing 12. In addition to the flexible member 23, an elastic member 25 (e.g., a spring) is also disposed in the recessed portion 22 of the battery module 20, wherein the elastic member 25 connects the battery module 20 with the flexible member 23.
Please refer to FIGS. 4A-4C. To assemble the battery module 20 and the main body 10, a user can push the battery module 20 into the through hole 11 of the main body 10 (as the arrow indicates in FIG. 4A) in a first direction (−X direction). As shown in FIG. 4B, when the battery module 20 is pushed into the through hole 11 of the main body 10, the flexible member 23 in the recessed portion 22 of the battery module 20 is forced and deformed. Here, the flexible member 23 is pressed by an external force in a second direction (−Y direction), and the elastic member 25 is compressed in the first direction (−X direction) due to deformation of the flexible member 23. Accordingly, the battery module 20 is allowed to be inserted into the through hole 11. In FIG. 4C, when the battery module 20 keeps moving in the first direction (−X direction), an end of the flexible member 23 is engaged with the notch 123 on the top portion 121 of the housing 12, so that the battery module 20 is fixed in a joining position with respect to the main body 10, to accomplish the assembly of the battery module 20 and the main body 10.
In this embodiment, when the battery module 20 is in a joining position with respect to the main body 10, the metal sheets 24 on the battery module 20 are engaged with several cavities (not shown) on the top portion 121, so that the connection strength between the battery module 20 and the main body 10 can be enhanced, to prevent the battery module 20 from falling off from the main body 10. In addition, when the battery module 20 is in a joining position with respect to the main body 10, the battery module 20 can be electrically connected to the circuit module of the main body 10 by some electrical contacts (not shown) on the top portion 121, so that power can be supplied from the battery module 20 for the electronic device 1 to perform various functions.
Referring to FIG. 4D, to take off or replace the battery module 20, the user can use his or her hand or another battery module to push the flexible member 23 (as the arrow indicates in FIG. 4D) in the first direction (−X direction), so that the flexible member 23 is deformed due to the external force, and the battery module 20 can be detached from the main body 10. Accordingly, the user can replace or take off the battery module 20 from the main body 10.
It should be noted that, when the battery module 20 is in a joining position with respect to the main body 10 (FIG. 4C), an indentation 14 is formed between the top portion 121 and the bottom portion 122, so that the flexible member 23 would not be touched or pressed when using the electronic device 1, not only to prevent the battery module 20 from falling off the main body 10, but also to add to the aesthetic appearance of the wearable electronic device 1.
FIG. 5 is a schematic diagram of a wearable electronic device 1′ according to another embodiment of the invention, and FIG. 6 is an exploded diagram of the wearable electronic device 1′ in FIG. 5. Referring to FIGS. 5-6, the electronic device 1′ primarily comprises a main body 10′, a battery module 20′, and two wearing portions 30 and 40, wherein the wearing portions 30 and 40 are the same as the wearing portions 30 and 40 in the previous embodiment (FIG. 2). As shown in FIG. 6, the main body 10′ has a through hole 11′, a housing 12′, and a circuit module (not show), wherein the housing 12′ has a top portion 121′ and a bottom portion 122′, and the though hole 11′ is formed between the top portion 121′ and the bottom portion 122′ and extended through the housing 12′.
Referring to FIGS. 6-7, FIG. 7 is a partial cross-sectional view taken along lines A-A and B-B in FIG. 6. The main difference between the wearable electronic device 1′ in FIG. 7 and the wearable electronic device 1 in FIG. 3 is that the structures of the main body 10′ and the battery module 20′ are different from those of the main body 10 and the battery module 20. In this embodiment, the top portion 121′ of the main body 10′ has a stopper 124 and an engaging member 125, wherein the stopper 124 and the engaging member 125 are disposed on opposite sides of the top portion 121′. The battery module 20′ has a first side 201′ and a second side 202′, wherein at least one metal pad 21, a groove 26, and a recess 27 are formed on a surface 203′ of the battery module 20′, and the groove 26 and the recess 27 are disposed on opposite sides of the battery module 20′. As shown in FIGS. 6-7, the groove 26 is formed on the first side 201′, and the recess 27 is formed on the second side 202′.
Referring to FIGS. 8A-8C, when assembling the main body 10′ to the battery module 20′, the user can push the battery module 20′ into the through hole 11′ of the main body 10′ (FIG. 8) in the first direction (−X direction). With the battery module 20′ being pushed in the first direction (−X direction), the stopper 124 of the top portion 121′ of the housing 12′ is engaged with the groove 26 of the battery module 20′, to restrict the battery module 20′ in the through hole 11′. In this state, the engaging member 125 on the housing 12′ is aligned with the recess 27 of the battery module 20′ (FIG. 8B). Subsequently, the user can push the engaging member 125 downwardly with respect to the top portion 121′, so that the engaging member 125 is engaged with the recess 27 of the battery module 20′ (FIG. 8C). Thus, the assembly of the battery module 20′ and the main body 10′ is achieved.
To detach the battery module 20′ from the main body 10′, the user can push the engaging member 125 upwardly, so that the engaging member 125 separates from the recess 27. Accordingly, the user can push the battery module 20′ (as the arrow indicates in FIG. 8D) in the opposite direction from the first direction (X direction) from the second side 202′ of the battery module 20′. Therefore, the battery module 20′ is separated from the main body 10′.
FIG. 9 is a schematic diagram of a battery module 20′′ according to another embodiment of the invention. The main difference between the battery module 20′′ in FIG. 9 and the battery module 20′ in FIGS. 6 is that the battery module 20′′ further has an elastic rubber member 28 disposed around the metal pads 21. When the battery module 20′′ is in the joining position with respect to the main body 10′, the elastic rubber member 28 is in contact with the top portion 121′ of the housing 12′, so that the battery module 20′′can be protected from water entry, short-circuits, and rust from the wearable electronic device. In some embodiments, only one soft or hard wearing portion may be provided to the wearable electronic device 1 or 1′ embodiments for convenient usage.
In summary, a wearable electronic device is provided, comprising at least a wearing portion, a main body, and a battery module, wherein a through hole is formed in the main body for receiving the battery module, so that the easy and rapid assembly and detachment between the battery module and the main body can be achieved. Moreover, a user can replace or take off the battery module from the main body without taking off the whole wearable electronic device, so as to facilitate convenient usage.
