Description

Technical Field

[0001] The present disclosure relates to a watch band and a smart watch including the watch band. Background Art

[0002] Recently, healthcare wearable devices with various functions have been used, and a representative one is a smart watch. The smart watch has various functions, such as measuring changes in the body and recording movements during exercise, and measuring and analyzing the user's physical condition (such as the number of steps, heart rate, and stress index) during daily life. Therefore, different from conventional watches, more and more users use smart watches all day long, even during exercise, bathing, and sleep.

[0003] A lithium-ion battery can be used as a battery for a smart watch. The lithium-ion battery may be deformed at high temperatures or due to impact. To prevent the battery from being damaged by the structure in contact with the battery (which may cause problems such as rupture or explosion), it is necessary to ensure sufficient space for installing the battery. However, the size of the watch head of the smart watch is limited, and accordingly, the battery installation space is also limited.

[0004] In addition, as smart watches are developed to have more and more functions, the number of components installed inside the watch head increases, which limits the battery installation space and shortens the battery life due to the battery being consumed faster. Since traditional smart watches need to perform various functions with a limited battery capacity (as described above), the available time of the smart watch is shortened, which causes the inconvenience that the smart watch needs to be charged frequently. Summary of the Invention

The watch band 300 may include a conventional buckle.

[0048] Figure 3 is Figure 1 an exploded perspective view of the support portion 210 and the watch band 300 of the smart watch shown in Figure 4 is Figure 1 an exploded perspective view of the watch band of the smart watch shown in Figure 5 is Figure 4 an exploded perspective view of the terminal housing and the hinge coupling unit of the watch band shown in Figure 6 is Figure 4 a perspective view of the coupling state between the all-solid-state battery 320 and the hinge coupling unit 360 of the watch band shown in

[0049] Referring to Figures 3 to 6, the watch band 300 may include: a plurality of band blocks 310 arranged continuously in one direction; and a plurality of hinge coupling units 360 pivotally coupled to both sides of the plurality of band blocks 310 to connect the plurality of band blocks 310 to each other. Additionally, the watch band 300 may include a fastening block 370 that connects the support portion 210 and the plurality of band blocks 310 to each other.

[0050] The fastening block 370 may be coupled to one of the plurality of band blocks 310 positioned closest to the support portion 210 among the plurality of band blocks 310 through a pair of hinge coupling units 360. The fastening block 370 may be located between a pair of flanges 220 and mechanically coupled to the pair of flanges 220 using a fastening device such as a screw. However, this fastening configuration is merely an example, and the fastening block 370 and the pair of flanges 220 may be coupled to each other in various ways.

[0051] The all-solid-state battery 320 having electrode terminal units 340 on both of its sides may be embedded in at least one of the plurality of band blocks 310. In some embodiments, the all-solid-state battery 320 includes a first electrode terminal unit 340 and a second electrode terminal unit 340 respectively located on two side surfaces of the all-solid-state battery 320. Additionally, at least one of the plurality of hinge coupling units 360 may be electrically connected to the electrode terminal unit 340 of the all-solid-state battery 320. For example, the all-solid-state battery 320 may be embedded in all of the plurality of band blocks 310, and all of the plurality of hinge coupling units 360 may be electrically connected to the electrode terminal unit 340 of the all-solid-state battery 320.

[0052] The band block 310 may include the all-solid-state battery 320 and a battery case 350 surrounding the all-solid-state battery 320. The all-solid-state battery 320 may include a battery body 330 and electrode terminal units 340 positioned on both sides of the battery body 330. The battery body 330 may include a solid electrolyte 331 and a first electrode 332 and a second electrode 333 positioned such that the solid electrolyte 331 is interposed therebetween. The first electrode 332 may be a positive electrode, and the second electrode 333 may be a negative electrode. In some embodiments, the first electrode terminal unit 340 is located on a side surface of the first electrode that does not contact the solid electrode, and the second electrode terminal unit 340 is located on a side surface of the second electrode that does not contact the solid electrode.

[0053] The solid electrolyte 331 serves as a medium for transferring ions between the first electrode 332 and the second electrode 333. For example, the solid electrolyte 331 may include at least one of a garnet-type solid electrolyte, a lithium superionic conductor (LiSICON)-type solid electrolyte, a perovskite-type solid electrolyte, and a sodium (Na) superionic conductor (NaSICON)-type solid electrolyte.

Since the all-solid-state battery 320 uses a solid electrolyte instead of a liquid electrolyte, the all-solid-state battery 320 is not easily deformed by external shocks and can operate stably even in a harsh environment of high temperature and high pressure.

[0055] The electrode terminal unit 340 may include a terminal plate 341 and two terminal protrusions 342 (such as a first terminal protrusion 342 and a second terminal protrusion 342) protruding outward from the terminal plate 341. The two terminal protrusions 342 may be positioned at a certain distance from each other in the longitudinal direction of the watch band 300 ( Figure 4 the y-direction in). The two electrode terminal units 340 may be attached to the side surfaces of the all-solid-state battery 320 and face each other in the longitudinal direction of the all-solid-state battery 320 ( Figure 4 the x-direction in), with the battery body 330 interposed between the two electrode terminal units 340.

[0056] The battery case 350 may include a main body case 351 surrounding the battery body 330 and a terminal case 352 surrounding the electrode terminal unit 340.

[0057] The main body case 351 may be hollow and open on both sides. The terminal case 352 may include a plate cover 353 covering the terminal plate 341, two protrusion covers 354 respectively surrounding the two terminal protrusions 342, and an assembly protrusion 355 inserted into and assembled with the main body case 351. The main body case 351 and the terminal case 352 may be detachably coupled to each other. A predetermined gap may exist between the terminal protrusion 342 and the protrusion cover 354.

[0058] In the assembly of the all-solid-state battery 320 located in the band block 310, four terminal protrusions 342 may be exposed to the outside (two terminal protrusions 342 are exposed to the outside on each of the side surfaces of the all-solid-state battery 320), and the other components may be accommodated inside the battery case 350. A plurality of all-solid-state batteries 320 may be continuously arranged in one direction in such a manner that the first electrodes 332 are on the same side and the second electrodes 333 are on the same side inside the plurality of battery cases 350.

[0059] The hinge coupling unit 360 may be located on both sides of two adjacent tape blocks 310 and may be coupled to the two adjacent tape blocks 310. The hinge coupling unit 360 may include a hinge plate 361 and two hinge shafts 362 fixed to the hinge plate 361, such as a first hinge shaft 363 and a second hinge shaft 363. The hinge shafts 362 may have a shape similar to a hollow tube and may be fitted into the gap between the terminal protrusion 342 and the protrusion cover 354. The hinge shaft 362 may be electrically connected to the terminal protrusion 342 by contacting the terminal protrusion 342, and the terminal protrusion 342 and the hinge shaft 362 may rotate relative to each other.

[0060] The hinge plate 361 may face two adjacent tape blocks 310, and the two hinge shafts 362 (such as a first hinge shaft 362 and a second hinge shaft 362) may be coupled to the terminal protrusion 342 of one tape block 310 and the terminal protrusion 342 of another tape block 310 adjacent to the one tape block 310. That is, the hinge coupling unit 360 may connect two all-solid-state batteries 320 embedded in two adjacent tape blocks 310 in parallel with each other. In some embodiments, each of the first electrode terminal unit 340 and the second electrode terminal unit 340 includes a first terminal protrusion 342 and a second terminal protrusion 342. The first hinge shaft 362 may be pivotally coupled to the second terminal protrusion of one of two adjacent first electrode terminal units 340, or the second terminal protrusion of one of two adjacent second electrode terminal units 340, and the second hinge shaft 362 may be pivotally coupled to the first terminal protrusion of one of two adjacent first electrode terminal units 340, or the first terminal protrusion of one of two adjacent second electrode terminal units 340. Therefore, a plurality of all-solid-state batteries 320 may be connected to each other in such a way that the first electrodes 332 are electrically connected to each other and the second electrodes 333 are electrically connected to each other through a plurality of hinge coupling units 360.

[0061] The hinge plate 361 and the two hinge shafts 362 may be surrounded by a hinge housing 363. Two openings may be located in the hinge housing 363 to expose the two hinge shafts 362 respectively.

[0062] The hinge coupling unit 360 may be located on both sides of the fastening block 370 and the tape block 310 to couple the fastening block 370 and the tape block 310 to each other. Here, a pair of connection terminals 380 may be located inside the fastening block 370, and the first ends 381 of the connection terminals 380 may be exposed on both sides of the fastening block 370. The two hinge shafts 362 provided in the hinge coupling unit 360 may be coupled to the first end 381 of the fastening block 370 and the terminal protrusion 342 of the tape block 310 to electrically connect the all-solid-state battery 320 and the connection terminal 380 to each other.

[0063] In addition, the second end 382 of the connection terminal 380 may be exposed to the inner surface of the fastening block 370 facing the support portion 210, and a pair of input terminals 230 may be located on the outer peripheral surface of the support portion 210 facing the fastening block 370. The pair of input terminals 230 may be electrically connected to the power supply unit 170 (see Figure 2 ), and when the support portion 210 and the fastening block 370 are coupled to each other, the pair of input terminals 230 may be connected to the pair of second ends 382. Accordingly, the plurality of all-solid-state batteries 320 may be electrically connected to the power supply unit 170 through the plurality of hinge coupling units 360, the pair of connection terminals 380, and the pair of input terminals 230.

[0064] Returning to Figure 1 and Figure 2 , the smartwatch 100 according to the embodiment may be operated by receiving power together from the all-solid-state battery 320 accommodated in the strap 300 and the built-in battery accommodated in the support portion 210. Since the all-solid-state battery 320 is a safe battery that does not leak due to external shock or expansion, the all-solid-state battery 320 is suitable for being embedded in the strap 300 that is in direct contact with the user's skin.

[0065] Accordingly, compared to a conventional smartwatch that uses only a built-in battery, the smartwatch 100 according to the present embodiment may increase the battery duration and the usage time of the smartwatch 100, and increase the number of charging cycles to maximize user convenience.

[0066] Figure 7 is a perspective view of a smartwatch according to another embodiment. Figure 8 is Figure 7 an exploded perspective view of the smartwatch shown in

[0067] Referring to Figure 7 and Figure 8 , except that the fastening block 370 is omitted and the hinge coupling unit 360 is directly coupled to the support portion 240, the smartwatch 400 according to the present embodiment may have the same basic configuration as the smartwatch 100 according to the embodiment described with reference to Figures 1 to 6 .

[0068] In the smartwatch 400 according to the present embodiment, three flanges may be located on both sides of the support portion 240. The three flanges may include a central flange 251 and side flanges 252 positioned on both sides of the central flange 251. A recess 260 may be located between the central flange 251 and each side flange 252.

[0069] Multiple strip blocks 310 embedded with all-solid-state batteries 320 can face the central flange 251 and can be arranged continuously in one direction. Multiple hinge coupling units 360 surrounded by corresponding hinge cases 363 can face the two recesses 260 and can be arranged continuously in one direction. Among the multiple hinge coupling units 360, the hinge coupling unit 360 positioned closest to the support part 240 can be coupled to the support part 240 in the recess 260.

[0070] Specifically, the hinge coupling unit 360 can be received in the recess 260 and can be mechanically coupled to the central flange 251 and the side flange 252 using fastening means such as screws. In addition, the input terminals 270 can be located on both sides of the central flange 251. One of the two hinge shafts 362 provided in the hinge coupling unit 360 can be coupled to the terminal protrusion 342 of the strip block 310, and the other can be coupled to the input terminal 270 to electrically connect the input terminal 270.

[0071] The input terminal 270 of the central flange 251 can be electrically connected to the power supply unit 170 (see Figure 2 )). The multiple all-solid-state batteries 320 can be connected in parallel with each other through the multiple hinge coupling units 360 and can be electrically connected to the power supply unit 170 through the multiple hinge coupling units 360 and a pair of input units 270 (see Figure 2 ).

[0072] In the smartwatch 400 according to the present embodiment, the length of the hinge case 363 measured in the longitudinal direction ( Figure 8 the x direction in) of the all-solid-state battery 320 can be about 0.5 times or more and less than 1 time the length of the strip block 310. Here, the multiple hinge cases 363 and the multiple strip blocks 310 can look like including three rows of blocks.

[0073] Although the embodiments of the present disclosure have been described above, the present disclosure is not limited thereto, and various modifications can be made within the scope of the claims, the specification, and the drawings, and these modifications also fall within the scope of the present disclosure.
