[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] In the present invention, terms such as "upper," "lower," "left," "right," "front," "back," "top," "bottom," "inner," "outer," "center," "vertical," "horizontal," "transverse," and "longitudinal" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are primarily intended to better describe the present invention and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0040] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0041] Furthermore, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0042] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0043] A flip smart watch usually includes a host, a hinge assembly and a bottom bracket. The host includes a shell, a display screen arranged on the shell, a camera, a battery and a chip arranged on the shell. The shell and the bottom bracket are rotatably connected through the hinge assembly, so that the host can rotate relative to the bottom bracket to adjust the shooting angle to meet the user's different shooting needs.

[0044] The above-mentioned smart watches, such as Figure 1 As shown, the hinge assembly 03 is typically fixed to the housing by screws, with the screws located on the side of the housing. However, the thickness of a smartwatch is generally limited. Attaching screws to the side of the housing can easily result in thinner walls in the screw holes through which the screws pass, weakening the housing's structural strength at this point. Consequently, after the main unit 01 rotates a certain number of times relative to the bottom bracket 02, or when the main unit 01 is subjected to significant force during rotation, cracks can easily form at the location where the housing is connected to the screws, causing the screws to come out.

[0045] In view of this, the present invention provides a smart wearable device, which can effectively improve the structural strength of the position where the screws are installed on the host, and effectively improve the service life of the smart wearable device.

[0046] The technical solution of the present application will be described in detail below with reference to specific embodiments and drawings. The present application embodiment provides a smart wearable device, such as Figure 2-Figure 4 As shown, the smart wearable device 10 includes a housing 1, a bottom bracket 2, and a hinge assembly 3. The housing 1 includes a middle frame 11, which has a first surface 111 with screw holes 1111 disposed thereon. The housing 1 is rotatably connected to the bottom bracket 2 via the hinge assembly 3, allowing the housing 1 and the bottom bracket 2 to rotate between a closed state and an extended state. The hinge assembly 3 is secured to the middle frame 11 via screws 4 disposed in the screw holes 1111. When the housing 1 and the bottom bracket 2 are in the closed state, the first surface 111 faces toward or away from the bottom bracket 2.

[0047] In this embodiment, the shell 1 is rotatably connected to the bottom bracket 2 through the shaft assembly 3, so that the shell 1 and the bottom bracket 2 can rotate between a closed state and an expanded state, so that the shell 1 can be rotated relative to the bottom bracket 2 according to the needs of the user, so that the display screen, camera and other structures arranged on the shell 1 can be rotated to different angles according to the needs of the user, thereby facilitating the user's use.

[0048] The hinge assembly 3 is fixed to the middle frame 11 by means of screws 4 passed through the screw holes 1111, so that when the shell 1 rotates relative to the bottom bracket 2, the hinge assembly 3 can be more firmly arranged on the middle frame 11, so that the shell 1 can rotate more smoothly relative to the bottom bracket 2.

[0049] Among them, a screw hole 1111 is provided on the first surface 111. When the shell 1 and the bottom bracket 2 are in a closed state, the first surface 111 faces the bottom bracket 2 or turns away from the bottom bracket 2, and is located on the side of the shell 1 relative to the screw hole. On the one hand, the first surface 111 can have a larger space, so that the screw hole 1111 for passing the screw 4 can be set at a relatively inner position of the first surface 111, so that the thinnest dimension between the hole wall of the screw hole 1111 and the outer surface of the shell 1 can be larger, so that the hole wall of the screw hole 1111 can withstand a larger force, thereby improving the structural strength of the position where the screw 4 is connected to the middle frame 11, and then when the shell 1 rotates relative to the bottom bracket 2, the screw 4 can not easily fall out of the screw hole 1111, effectively improving the service life of the smart wearable device 10; on the other hand, the setting of the screw hole 1111 does not need to consider the thickness of the shell 1, which is conducive to the lightweight setting of the shell 1, thereby facilitating the lightweight setting of the smart wearable device 10.

[0050] The bottom bracket 2 may be a plate-shaped structure or a frame-shaped structure, which is not limited here.

[0051] The smart wearable device 10 can be a smart watch, a smart bracelet, etc., which is not limited here.

[0052] The aforementioned rotating shaft assembly 3 may include a rotating shaft, which is connected to the middle frame 11 via screws 4. The rotating shaft is also connected to the bottom bracket 2, so that the housing 1 can rotate relative to the bottom bracket 2 via the rotating shaft. Furthermore, the number of rotating shafts may be one or two, and is not limited here.

[0053] Alternatively, as Figure 5-Figure 7 As shown, the shaft assembly 3 includes two Figure 6 The middle frame 11 includes a rotating end, a accommodating cavity 112 is provided on the rotating end, and there are two screw holes 1111. The two screw holes 1111 are both provided on the first surface 111 and are respectively located on both sides of the accommodating cavity 112 along the first direction. The two rotating shafts 31 correspond to the two screw holes 1111, and each rotating shaft 31 is fixed in the accommodating cavity 112 by a screw 4 passing through the corresponding screw hole 1111.

[0054] Therefore, the two rotating shafts 31 are respectively fixed by corresponding screws 4. Compared with the method in which the rotating shaft assembly 3 includes one rotating shaft 31 and the rotating shaft 31 is fixed by one screw 4, the force applied to each screw 4 can be smaller, so that the screw 4 is less likely to fall out of the screw hole 1111 when subjected to a larger force.

[0055] The structures of the two rotating shafts 31 may be substantially the same, so that the two rotating shafts 31 can have good interchangeability, which facilitates the installation of the two rotating shafts 31 .

[0056] In addition, there are many ways to implement the rotation shaft 31 being fixed to the accommodating cavity 112 by the screw 4 passing through the screw hole 1111. For example, the rotation shaft assembly 3 may further include a connecting member, one end of which is sleeved on the rotation shaft 31, and the other end of which extends out of the accommodating cavity 112 and bends to extend to the position where the screw hole 1111 is provided on the first surface 111, and the other end of which is provided with a through hole, and the screw 4 can pass through the through hole and the screw hole 1111 in sequence to fix the rotation shaft 31 in the accommodating cavity 112; or alternatively, the rotation shaft 31 is provided with a threaded hole corresponding to the screw hole 1111, and the screw 4 can pass through the screw hole 1111 and the threaded hole in sequence to fix the rotation shaft 31 in the accommodating cavity 112. Of course, there are other ways to implement the rotation shaft 31 being fixed to the accommodating cavity 112 by the screw 4 passing through the screw hole 1111, which is not limited here.

[0057] Alternatively, as Figure 7 As shown, the housing 1 further includes a first decorative piece 12 , which is disposed on both sides of the middle frame 11 along the first direction. A portion of the first decorative piece 12 extends to the first surface 111 and is spaced apart from the screw hole 1111 .

[0058] In this way, a certain distance can be created between the first decorative piece 12 and the screw 4 passed through the screw hole 1111, so that when the screw 4 and the first decorative piece 12 are disassembled and assembled, the two will not affect each other, thereby facilitating the assembly and subsequent maintenance of the smart wearable device 10.

[0059] Among them, when the rotating shaft 31 is connected to a connecting part, the connecting part is connected to the middle frame 11 by a screw 4 so that the rotating shaft 31 is fixed on the middle frame 11, and part of the connecting part is located on the first surface 111, the connecting part can be spaced apart from the part of the first decorative part 12 located on the first surface 111, or the edge parts of the two just contact each other, so that when disassembling the rotating shaft assembly 3, there is no need to consider the first decorative part 12, that is, tightening the screw 4 can realize the installation of the rotating shaft assembly 3, and loosening the screw 4 can realize the disassembly of the rotating shaft assembly 3, which facilitates the disassembly and assembly of the rotating shaft assembly 3, thereby facilitating the assembly and subsequent maintenance of the smart wearable device 10.

[0060] Optionally, the screw hole 1111 is located in an area between the accommodating cavity 112 and the first decorative piece 12 on the first surface 111, and is arranged near the inner side of the middle frame 11 relative to the rotating shaft 31 along a direction perpendicular to the first direction and parallel to the first surface 111.

[0061] In this way, the minimum dimension between the hole wall of the screw hole 1111 and the outer surface of the middle frame 11 can be larger, that is, the hole wall of the screw hole 1111 can have a thicker thickness, and the part of the first decorative part 12 located on the first surface 111 can have a larger area, so as to have a better decorative effect on the shell 1 and improve the aesthetics of the shell 1. At the same time, the distance between the screw hole 1111 and the part of the first decorative part 12 located on the first surface 111 can be larger, which makes it easier to disassemble and assemble the screw 4.

[0062] The connection between the first decorative member 12 and the middle frame 11 can be achieved in various ways. In one possible implementation, a buckle can be provided on the first decorative member 12 and a corresponding slot can be provided on the middle frame 11. The buckle is engaged with the slot to achieve the connection between the first decorative member 12 and the middle frame 11, making it easy to assemble and disassemble the first decorative member 12 and the middle frame 11.

[0063] In another possible implementation, the first decorative component 12 is bonded to the middle frame 11 by adhesive, or is threadedly connected to the middle frame 11 by screws.

[0064] In this way, the connection between the first decorative piece 12 and the middle frame 11 can be made stronger, reducing the probability of the first decorative piece 12 being separated from the middle frame 11 due to collision, thereby reducing the probability of the first decorative piece 12 needing repair due to separation from the middle frame 11.

[0065] In some embodiments, as Figure 3-Figure 8 As shown, the hinge assembly 3 includes a hinge 31, a connecting bracket 32 ​​and a hinge housing 33. The hinge housing 33 is sleeved on the hinge 31, and the end of the hinge 31 extends out of the hinge housing 33 and is connected to the connecting bracket 32. The connecting bracket 32 ​​is fixed to the middle frame 11 by a screw 4 passed through the screw hole 1111. When the shell 1 and the bottom bracket 2 are in the expanded state, the hinge housing 33 abuts against the bottom bracket 2. When the shell 1 and the bottom bracket 2 are in the closed state, the first surface 111 of the shell 1 abuts against the bottom bracket 2.

[0066] Therefore, compared with setting the screw hole 1111 on the side of the middle frame 11 close to the hinge assembly 3, when the shell 1 is rotated to an angle of 90° with the bottom bracket 2, the length of the force arm of the force applied to the screw 4 can be effectively increased, so that under the condition of the same force torque, the force applied to the screw 4 can be effectively reduced, making it difficult for the screw 4 to fall out of the screw hole 1111, and the force applied to the middle frame 11 in contact with the screw 4 can also be reduced, making it difficult for cracks, breakages, etc. to occur at the position of the middle frame 11 connected to the screw 4, making it more difficult for the screw 4 to fall out of the screw hole 1111, thereby ensuring the normal operation of the hinge assembly 3.

[0067] It should be explained that the above-mentioned rotation of the shell 1 to an angle of 90° with the bottom bracket 2 means that the angle between the shell 1 and the bottom bracket 2 is 90° or close to 90°, and does not mean that the angle between the shell 1 and the bottom bracket 2 must be 90°.

[0068] For example, Figure 8As shown, when the shell 1 is rotated to an angle of 90° with the bottom bracket 2, the end of the shaft housing 33 away from the first surface 111 abuts against the bottom bracket 2, that is, the end of the shaft housing 33 away from the first surface 111 will be subjected to pressure applied by the bottom bracket 2. At this time, the screw 4 is located on the first surface 111. Compared with the screw being located on the side of the middle frame 11 close to the bottom bracket 2, the force arm of the force applied to the screw 4 can be longer, so that under the same force torque, the force applied to the screw 4 can be smaller, and at the same time, the force applied to the position connected to the screw 4 in the middle frame 11 can be smaller, so that the screw 4 is not easy to fall out of the screw hole 1111, thereby optimizing the force-bearing capacity of the shaft assembly 3. In addition, when the shell 1 is rotated to an angle of 90° with the bottom bracket 2, the hinge assembly 3 may be subjected to a force to disengage toward the outside of the middle frame 11, so that the screw 4 is subjected to a force toward the outside of the screw hole 1111. At this time, the screw 4 is located on the first surface 111, so that the angle between the force exerted on the screw 4 and the screw hole 1111 can be larger, for example, the angle can reach 45°, so that the axial force exerted on the screw 4 along the screw hole 1111 can be smaller, thereby making it difficult for the screw 4 to disengage from the screw hole 1111.

[0069] In some embodiments, the wall thickness of the screw hole 1111 is greater than or equal to 1.4 mm. This allows the wall of the screw hole 1111 to have a high structural strength, thereby preventing cracks from occurring in the wall of the screw hole 1111 when subjected to a large force, and preventing the screw 4 from being dislodged from the screw hole 1111 when subjected to a large force.

[0070] The wall thickness of the screw hole 1111 may be 1.4 mm, 1.5 mm, 1.6 mm, etc., which is not limited here.

[0071] In other embodiments, Figure 9 As shown, the middle frame 11 has a second surface 113 opposite to the first surface 111 and a side surface connected between the first surface 111 and the second surface 113, and a display screen is arranged on the second surface 113; the shell 1 also includes a second decorative member 13, and the second decorative member 13 is arranged in the area of ​​the middle frame 11 close to the hinge assembly 3. The second decorative member 13 includes a first decorative portion 131, a second decorative portion 132 and an intermediate decorative portion 133 connected to the first decorative portion 131 and the second decorative portion 132. The first decorative portion 131 is located on the first surface 111, the second decorative portion 132 is located on the second surface 113, and the intermediate decorative portion 133 is located on the side of the middle frame 11 close to the hinge assembly 3.

[0072] Thus, the housing 1 can have better aesthetics.

[0073] Among them, the second decorative piece 13 and the middle frame 11 can be implemented in many ways, for example, the second decorative piece 13 can be bonded to the middle frame 11 by adhesive; or the second decorative piece 13 can be threadedly connected to the middle frame 11 by screws; or the second decorative piece 13 can be clipped to the middle frame 11 by snaps, which is not limited here.

[0074] Alternatively, as Figure 9 As shown, the housing 1 further includes a bottom decorative piece 14 , which is disposed on the first surface 111 and connected to the middle frame 11 by glue or screws. The edge of the first decorative portion 131 is located between the middle frame 11 and the bottom decorative piece 14 .

[0075] Thus, the first decorative part 131 of the second decorative part 13 can be pressed against the middle frame 11 through the bottom decorative part 14. When the bottom decorative part 14 and the second decorative part 13 are assembled to the middle frame 11, the second decorative part 13 is placed in place and the bottom decorative part 14 is assembled to the middle frame 11. When the bottom decorative part 14 and the second decorative part 13 are disassembled from the middle frame 11, the second decorative part 13 can be directly removed from the middle frame 11 after the bottom decorative part 14 is removed, which facilitates the disassembly and assembly of the second decorative part 13, the bottom decorative part 14 and the middle frame 11, thereby reducing the difficulty of disassembly and assembly of the smart wearable device 10.

[0076] In addition, the portion of the bottom decorative piece 14 close to the screw hole 1111 can protrude toward the screw hole 1111 and cover the screw 4 passing through the screw hole 1111 to hide the screw 4 and improve the aesthetics of the housing 1.

[0077] Alternatively, as Figure 9 and Figure 10 As shown, a first limiting protrusion 1311 is provided on the side of the first decorative portion 131 facing the first surface 111, and a first limiting groove (not shown in the figure) matching the first limiting protrusion 1311 is provided on the first surface 111, and the first limiting protrusion 1311 is embedded in the first limiting groove.

[0078] Therefore, by embedding the first limiting protrusion 1311 in the first limiting groove, the first decorative part 131 is not easily slipped out from between the bottom decorative part 14 and the middle frame 11, which plays a certain limiting role on the first decorative part 131, thereby playing a certain limiting role on the second decorative part 13.

[0079] The shape of the first limiting protrusion 1311 can be any one of a prismatic structure, a dovetail structure, etc., which is not limited here. Correspondingly, the first limiting groove can be any one of a rectangular shape, a dovetail shape, etc., which is not limited here.

[0080] In addition, the number of the first limiting protrusions 1311 can be one, two, or more, which is not limited here.

[0081] Alternatively, as Figure 9 and Figure 10 As shown, a second limiting protrusion 1321 is provided on the side of the second decorative portion 132 facing the second surface 113. The second limiting protrusion 1321 and the first limiting protrusion 1311 both extend in a direction perpendicular to the first surface 111. A second limiting groove (not shown in the figure) matching the second limiting protrusion 1321 is provided on the second surface 113, and the second limiting protrusion 1321 is embedded in the second limiting groove.

[0082] Thus, the second limiting protrusion 1321 can be embedded in the second limiting groove, so that the second decorative part 132 is not easy to slide out of the middle frame 11, which has a certain limiting effect on the second decorative part 132, thereby having a certain limiting effect on the second decorative part 13; and in conjunction with the first limiting protrusion 1311 embedded in the first limiting groove, the second decorative part 13 is not easy to shake relative to the middle frame 11, so that the second decorative part 13 can be set more firmly on the middle frame 11.

[0083] The shape of the second limiting protrusion 1321 may be substantially the same as that of the first limiting protrusion 1311 , and will not be further described herein.

[0084] The number of the second limiting protrusions 1321 and the second limiting grooves can be one, two or more, which is not limited here.

[0085] In addition, a third retaining protrusion can be provided on the side of the middle decorative portion 133 facing the middle frame 11. The third retaining protrusion can extend in a direction parallel to the first surface 111. A third retaining groove can be provided on the side surface of the middle frame 11 to match the third retaining protrusion, and the third retaining protrusion is embedded in the third retaining groove.
