Description

Wearable devices Technical Field

[0001] The embodiments of the present disclosure relate to the field of display technology, and in particular to a wearable device. Background Art

[0002] Wearable devices, such as smartwatches, have attracted widespread attention for their attractive appearance and rich functionality. As demand for wearable devices grows, the need to increase or decrease the display area to enhance the user experience when handling different tasks, such as watching videos or making phone calls, is driving demand.

[0003] In related art, a wearable device includes a watch case and a flexible screen located on the watch case. The watch case includes an end cap structure, which includes a fixed portion and a sliding cover portion that is slidably connected to the fixed portion and can slide horizontally toward one side of the watch case. The end surface of the sliding cover portion and the end surface of the fixed portion are on the same plane or curved surface. The flexible screen includes a first portion fixedly covering the end surface of the sliding cover portion and a second portion that is normally retracted to the other side of the watch case via a winding mechanism. When the sliding cover portion slides out, the first portion pulls the second portion out of the watch case, causing it to move and cover the end surface of the fixed portion, thereby expanding the display area.

[0004] However, simply using hands to push the sliding cover to expand or shrink the flexible screen is not very convenient, which affects the user experience.

[0052] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0053] The terms used in the embodiments of the present disclosure are only used to explain the embodiments of the present disclosure and are not intended to limit the present disclosure. Unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should be the ordinary meanings understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second", "third" and similar words used in the patent application specification and claims of this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, similar words such as "one" or "a" do not indicate a quantitative limitation, but rather indicate the presence of at least one. Similar words such as "include" or "comprise" mean that the elements or objects appearing before "include" or "comprise" cover the elements or objects listed after "include" or "comprise" and their equivalents, and do not exclude other elements or objects.

[0054] Figures 1 and 2 are schematic diagrams of a wearable device in a closed and unfolded state, respectively, according to an embodiment of the present disclosure. As shown in Figures 1 and 2, the wearable device includes a sliding display device 1, a base 2, and a strap 3. The sliding display device 1 is connected to the base 2, and both ends of the strap 3 are connected to the base 2.

[0055] Figure 3 is a schematic structural diagram of a sliding display device and a base provided in an embodiment of the present disclosure. In conjunction with Figures 1 to 3, the sliding display device 1 includes a fixed portion 11, a movable portion 12, a flexible display panel 13 and a connecting component 14 (shown in Figure 4). The fixed portion 11 is connected to the base 2. The movable portion 12 is connected to the fixed portion 11. A portion of the flexible display panel 13 is connected to the fixed portion 11, and another portion of the flexible display panel 13 is connected to the movable portion 12. The movable portion 12 can slide in a first direction x relative to the fixed portion 11, thereby driving the flexible display panel to expand or close, thereby achieving enlargement or reduction of the display area of ​​the wearable device.

[0056] Optionally, when the wearable device is in the closed state, the aspect ratio of the display area of ​​the flexible display panel 13 can be 4:3; when the wearable device is in the unfolded state, the aspect ratio of the display area of ​​the flexible display panel 13 can be 16:9, 18:9, or 21:9, etc. When the wearable device is in the closed state and the unfolded state, the aspect ratio of the display area of ​​the flexible display panel 13 can be set according to actual needs, and the embodiments of the present disclosure do not impose any restrictions on this.

[0057] Figure 4 is a schematic diagram of the internal structure of a sliding display device provided in an embodiment of the present disclosure. Figures 5 and 6 are schematic diagrams of a sliding display device provided in an embodiment of the present disclosure in its closed and expanded states, respectively. As shown in Figures 4 to 6, the connecting assembly 14 includes an elastic connector 141, which is connected between the fixed portion 11 and the movable portion 12. The elastic connector 141 is used to provide a force that tends to move the movable portion 12 and the fixed portion 11 toward each other along the first direction x. Compared to simply manually pushing the movable portion to expand or close the flexible display panel 13, the provision of the elastic connector 141 can provide partial or full force during the relative closing process between the fixed portion 11 and the movable portion 12, reducing the difficulty and complexity of the user's operation. In one possible embodiment, as shown in Figures 4 to 6, in the sliding display device 1, the connecting assembly 14 includes two elastic connectors, namely, an elastic connector 141a and an elastic connector 141b, with the elastic connectors 141a and 141b being arranged opposite each other.

[0058] For example, the elastic connector 141 is a tension spring. Connecting assemblies that include compression springs require additional, complex retaining structures to provide the compression force, which typically takes up more space. Compared to connecting assemblies that include compression springs, connecting assemblies that include tension springs take up less space and are therefore suitable for use in small-sized wearable devices.

[0059] Optionally, the tension spring is a medium-light load spring. The medium-light load spring does not have too much elastic force to cause collision damage during the relative closing of the fixed portion 11 and the movable portion 12; nor does it have too little elastic force to prevent the relative closing of the fixed portion 11 and the movable portion 12 from being reduced or even eliminated by human effort.

[0060] Illustratively, the maximum load of a single tension spring in the embodiment of the present disclosure is 5N to 9N.

[0061] Exemplarily, the relative angles of the hooks at both ends of the tension spring are 90° or 180°.

[0062] Figure 7 is a partial schematic diagram of the internal structure of a sliding display device provided in an embodiment of the present disclosure. Figures 8 and 9 are partial schematic diagrams of the structure of a sliding display device provided in an embodiment of the present disclosure, respectively, in the closed and expanded states. As shown in Figures 7 to 9, the connecting assembly 14 further includes a limiting structure 142, which is connected to at least one of the movable portion 12 and the fixed portion 11. As shown in Figures 7 to 9, the limiting structure 142 is connected to the movable portion 12. The limiting structure 142 is used to limit the position of the elastic connector 141 in directions other than the first direction x. The provision of the limiting structure 142 limits the degree of freedom of movement of the elastic connector 141 to 1, allowing the elastic connector 141 to extend or contract only in the first direction x. This minimizes any sliding position deviation between the movable portion 12 and the fixed portion 11 caused by the deviation of the elastic connector 141, thereby improving the movement reliability of the sliding display device 1 when switching between the closed and expanded states.

[0063] In the embodiment of the present disclosure, referring again to Figure 4 or Figure 7, the limiting structure 142 includes a protrusion 1421, which is connected to the movable part 12, and has a limiting channel 14211. The middle part of the elastic connector 141 is located in the limiting channel 14211, so that the elastic connector 141 can only move in the limiting channel 14211; and the extension direction of the limiting channel 14211 is the first direction x, so the elastic connector 141 can only move along the first direction x.

[0064] It should be noted that, in order to clearly illustrate the state of the elastic connector 141 when the sliding display device is in the closed state and the unfolded state respectively, the elastic connector 141 in the embodiments shown in Figures 5 and 6 does not appear to be located in the limiting channel 14211, but in fact the middle part of the elastic connector 141 is actually still located in the limiting channel 14211.

[0065] In another possible embodiment, the limiting structure 142 is connected to the fixed portion 11 and is not connected to the movable portion 12. The limiting structure 142 includes a protrusion 1421 connected to the fixed portion 11. The protrusion 1421 defines a limiting channel 14211. The limiting channel 14211 extends in the first direction x, and the middle portion of the elastic connector 141 is located in the limiting channel 14211.

[0066] Optionally, the shape of the bump 1421 is a columnar structure with a hollow channel, and the cross-sectional shape of the columnar structure can be circular, triangular, quadrilateral, etc.

[0067] In another possible embodiment, a portion of the limiting structure 142 is connected to the fixed portion 11, and another portion is connected to the movable portion 12. These two portions of the limiting structure 142 together form a limiting channel, which limits the degree of freedom of movement of the elastic connector 141 to 1, so that the elastic connector 141 can only extend or shorten along the first direction x. For example, the portion of the limiting structure 142 connected to the fixed portion 11 is a first elongated baffle, the length direction of the first elongated baffle is the first direction x, and the width direction of the first elongated baffle is the thickness direction of the sliding display device; the portion of the limiting structure 142 connected to the movable portion 12 is a second elongated baffle, the length direction of the second elongated baffle is the first direction x, and the width direction of the second elongated baffle is the second direction y. The first elongated baffle, the second elongated baffle, the fixed portion 11, and the movable portion 12 form a limiting channel. Here, the second direction y is perpendicular to the first direction x and perpendicular to the thickness direction of the sliding display device.

[0068] In the disclosed embodiment, the first surface 14212 of the bump 1421 has at least two limiting holes 14213, and the at least two limiting holes 14213 are arranged along the first direction x. As shown in Figure 8, the first surface 14212 of the bump 1421 has two limiting holes 14213. The first surface 14213 is the surface of the bump 1421 that is closest to the center of the wearable device. Here, the at least two limiting holes 14213 correspond to the closed state, the expanded state, and the state between the closed and expanded states of the fixed portion 11 and the movable portion 12, respectively.

[0069] For example, as shown in FIG4 or FIG7 , the connection assembly 14 further includes a suspension assembly 143, which is located on the fixing portion 11 and is configured to be operably engaged with one of the at least two limiting holes 1421. This allows the wearable device to remain in a closed state, an expanded state, or a state between the closed and expanded states when the user stops manually operating the device, thus being applicable to a variety of usage scenarios and meeting the operating habits of different users.

[0070] Exemplarily, as shown in FIG4 or FIG7 , the hovering assembly 143 includes a first clip 1431, an elastic return member 1432, and a support member 1433. The first end of the first clip 1431 has a baffle 14312 that cooperates with the limiting hole 14213, and the first clip 1431 is located in the fixing portion 11. The second end of the first clip 1431 is located outside the fixing portion 11, and the support member 1433 is located in the fixing portion 11 and is located on the side of the first clip 1431 away from the protrusion 1421. The support member 1433 is connected to the fixing portion 11. One end of the elastic return member 1432 is located in the support member 1433, and the other end of the elastic return member 1432 abuts against the first clip 1431 and is configured to provide pressure to limit the baffle in the limiting hole 14213. The first clamping member 1431 matches the limiting hole 1421 , and is clamped with the limiting hole 1421 under the action of the elastic return member 1432 and the support member 1433 .

[0071] In one possible embodiment, the hover assembly further includes a second clip 1434, which is located in the fixing portion 11 and on a side of the first clip 1431 away from the protrusion 1421. The second clip 1434 is connected to the fixing portion 11. The first clip 1431 has a slot 14313, which is located on a surface of the first clip 1431 near the second clip 1434 and near the second end. The second clip 1434 is configured to be located in the slot 14313 when the baffle 14312 is located outside the limiting hole 14213, thereby securing the first clip 1431.

[0072] In one possible embodiment, as shown in FIG. 4 or FIG. 7 , the first engaging member 1431 includes a first rod 14311 and a baffle 14312 connected to each other. The baffle 14312 is located at one end of the first rod 14311 and engages with the limiting hole 14213. The other end of the first rod 14311 is located outside the fixed portion 11. The portion of the first rod 14311 located outside the fixed portion 11 is also referred to as the state switching block 14314. The second engaging member 1434 includes a second limiting baffle 14341. The second engaging member 1434 is connected to the fixed portion 11. The portion of the first rod 14311 located inside the fixed portion 11 and away from the first limiting baffle 14312 has a slot 14313, and the second limiting baffle 14331 engages with the slot 14313. The elastic return member 1432 is a spring. The support member 1433 is located in the area between the first rod 1430 and the center of the wearable device. One end of the elastic return member 1432 abuts against the first rod 14311.

[0073] 7 to 9 , the support member 1433 is fixedly connected to the fixing portion 11, for example, by screws. When the wearable device is in the closed state shown in FIG6 , the second limiting baffle 14341 engages with the locking slot 14313, and the baffle 14312 engages with the limiting hole 14213 of the away-state switching block 14314. At this time, the elastic force of the elastic return member 1432 applies a force along the second direction y, directed from the first rod 14311 toward the protrusion 1421, to the first rod 14311, thereby firmly engaging the baffle 14312 with the limiting hole 14213 of the away-state switching block 14314 and preventing it from coming out.

[0074] When the wearable device needs to be unfolded, the state switching block 14314 is shifted from a position close to the protrusion 1421 to a position away from the protrusion 1421, the elastic reset member 1432 is squeezed, and the baffle 14312 and the limiting hole 14313 of the away state switching block 14314 are changed from the clamping state to the non-clamping state, that is, the baffle 14312 is disengaged from the limiting hole 14313 of the away state switching block 14314. At this time, the movable part 12 can slide relative to the fixed part 11. When it slides to the baffle 14312 and the other limiting hole 14313, the movable part 12 can slide relative to the fixed part 11. When the state switching block 14314 contacts the limiting hole 14213 close to the state switching block 14314, the elastic force of the elastic return member 1432 applies a force along the second direction y, from the first rod member 14311 to the direction of the protrusion 1421, to the first rod member 14311, thereby driving the state switching block 14314 from a position away from the protrusion 1421 to a position close to the protrusion 1421, and making the baffle 14312 firmly engaged with the limiting hole 14213 and not easy to fall out, thereby keeping the wearable device in this relatively expanded state.

[0075] When the wearable device needs to be tightened, the state switching block 14314 is moved from the position close to the protrusion 1421 to the position away from the protrusion 1421 again, the elastic reset member 1432 is squeezed, and the baffle 14312 and the limiting hole 14313 close to the state switching block 14314 are changed from the clamping state to the non-clamping state, that is, the baffle 14312 is disengaged from the limiting hole 14313 close to the state switching block 14314. At this time, the movable part 12 can slide relative to the fixed part 11. When it slides to the baffle 14312 and the other limiting hole 14313, the movable part 12 can slide relative to the fixed part 11. When the state switching block 14314 contacts the limiting hole 14213 away from the state switching block 14314, the elastic force of the elastic return member 1432 applies a force to the first rod member 14311 along the second direction y, which is directed from the first rod member 14311 to the direction of the protrusion 1421, thereby driving the state switching block 14314 from a position away from the protrusion 1421 to a position close to the protrusion 1421, and making the baffle 14312 firmly engaged with the limiting hole 14213 and not easy to fall out, thereby keeping the wearable device in this relatively tightened state.
