Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more specifically, to a watch body and a wearable device. Background Technology

[0002] With the development of technology, wearable devices can be used to achieve more functions, and more and more users are choosing to wear wearable devices.

[0003] However, the small display size of wearable devices causes numerous inconveniences for users. Increasing the display size, however, limits the wearing method, increasing the gap between the wearable device and the user's wrist, leading to discomfort. Therefore, how to increase the display size of wearable devices while ensuring user comfort is a pressing issue that needs to be addressed. Summary of the Invention

[0004] This application provides a watch body and a wearable device. The watch body includes a housing and a flexible display screen. The flexible display screen and the housing are fixedly connected. The housing includes a first housing and a second housing that can rotate relative to the first housing.

[0005] In a first aspect, a watch body is provided, comprising: a flexible display screen; and a housing, wherein the flexible display screen is fixedly connected to the housing, and the housing includes a first housing, a second housing, and a first hinge; wherein the first hinge includes a first link, a second link, and a third link, a first end of the first link is fixedly connected to the first housing, a second end of the first link is slidably connected to the first end of the second link, a second end of the second link is slidably connected to the first end of the third link, and a second end of the third link is fixedly connected to the second housing.

[0006] According to an embodiment of this application, the housing includes a first housing and a second housing that can rotate relative to each other via a first hinge. Since the flexible display screen is fixedly connected to the housing, the flexible display screen can also bend as the first and second housings rotate relative to each other. Therefore, when a user wears the wearable device, the watch body can be in a folded or partially folded state, making the watch body fit the user's watch more closely and greatly improving wearing comfort. Simultaneously, when the watch body is in a partially folded or unfolded state, it has a larger display screen, thus providing a better user experience.

[0007] In conjunction with the first aspect, in some implementations of the first aspect, the first link and the second link are respectively provided with a first receiving groove and a first sliding block, and at least a portion of the first sliding block is located in the first receiving groove and is slidably connected to the first receiving groove.

[0008] According to an embodiment of this application, the first connecting rod and the second connecting rod are slidably connected via a first sliding block and a first receiving groove. When the first housing and the second housing rotate relative to each other, the first sliding block slides within the first receiving groove.

[0009] Similarly, the second and third links can also be slidably connected by a similar structure. For example, the second and third links are respectively provided with a second receiving groove and a second sliding block, with at least a portion of the second sliding block located within the second receiving groove and slidably connected to it.

[0010] In conjunction with the first aspect, in some implementations of the first aspect, the cross-section of the first receiving groove along the first direction is arc-shaped, and the virtual center of the first receiving groove is located in the flexible display screen, wherein the first direction is the direction from the first housing to the second housing.

[0011] According to the embodiments of this application, the virtual center O1 of the first receiving groove can be understood as the virtual center O1 of the area overlapping with the first sliding block in the cross section of the first receiving groove along the first direction when the watch body is in a folded state. For example, the virtual center O1 of the first receiving groove can be understood as the virtual center O1 of the arc surface on one side of the area overlapping with the first sliding block in the cross section of the first receiving groove along the first direction.

[0012] When the virtual center of the receiving slot is located on the flexible display screen, the first housing and the second housing rotate relative to each other, and the rotation angles of the multiple connecting rods are approximately the same. Since the rotation angles of the multiple connecting rods are approximately the same, when the watch body is in the first state and the second state, the distance between the first housing and the second housing along the flexible display screen is approximately the same. During the folding process (in different states), the watch body pulls or squeezes the flexible display screen.

[0013] In conjunction with the first aspect, in some implementations of the first aspect, the watch body further includes a first nut; the first connecting rod further includes a first threaded hole, through which the first nut passes and is fixedly connected to the first housing.

[0014] According to the embodiments of this application, the watch body may include a plurality of first nuts, and the first connecting rod may include a plurality of corresponding first screw holes to enhance the fixed connection strength between the first connecting rod and the first housing. This can be determined according to actual production or design, and for the sake of brevity, it will not be described in detail.

[0015] In actual production or design, other methods can also be used for fixing, and this application embodiment does not limit this. For example, the first connecting rod and the first housing can be connected by a snap-fit, or by adhesive, etc.

[0016] In conjunction with the first aspect, in some implementations of the first aspect, the watch body further includes a support member located between the housing and the flexible display screen; wherein the support member includes a first support portion, a second support portion, and a first flexible support portion, the first support portion being fixedly connected to the first housing, the second support portion being fixedly connected to the second housing, and the first flexible support portion being fixedly connected to the first hinge.

[0017] According to an embodiment of this application, the support layer can be used to support the flexible display screen, thereby isolating the flexible display screen from the components or parts disposed within the housing to avoid damage to the flexible display screen.

[0018] In conjunction with the first aspect, in some implementations of the first aspect, the first flexible support portion includes a first support rod and a flexible substrate, wherein the first support rod is fixedly connected to the flexible substrate; wherein the second connecting rod includes a first adhesive surface, wherein the first adhesive surface is fixedly connected to the first support rod.

[0019] According to an embodiment of this application, the first support rod and the first flexible substrate can be fixedly connected by casting a flexible material on the first support rod, and the cast flexible material can form the first flexible substrate.

[0020] When the first hinge comprises N links, each of the N links can include N-1 adhesive surfaces corresponding to different support rods. This can be understood as each of the N-1 links having one adhesive surface, each used for fixed connection with its corresponding support rod. Alternatively, it can be understood as some of the N links having two adhesive surfaces, while others do not have adhesive surfaces, and so on.

[0021] In one embodiment, the second link may include multiple first adhesive surfaces to enhance the strength of the fixed connection between the second link and the first support rod.

[0022] In conjunction with the first aspect, in some implementations of the first aspect, the first adhesive surface and the first support rod are respectively provided with a first positioning post and a first positioning hole, and at least a portion of the first positioning post is located in the first positioning hole.

[0023] According to an embodiment of this application, during the assembly process of the watch body, the first positioning post and the first positioning hole can be used for positioning between the first adhesive surface and the first support rod, thereby improving the accuracy of the first hinge and the first flexible support during the assembly process.

[0024] In conjunction with the first aspect, in some implementations of the first aspect, the flexible display screen includes a first display section and a second display section, the first display section corresponding to the first housing and the second display section corresponding to the second housing; based on the watch body being in a folded state, the angle between the first display section and the second display section is greater than or equal to 120° and less than 180°.

[0025] According to the embodiments of this application, only the angle between the first housing and the second housing (or, it can also be understood as the angle between the first housing and the second housing) is described as an obtuse angle. Due to the complementary nature of angles, this angle can also be converted to an acute angle. For example, the angle between the first display unit and the second display unit (the angle between the first housing and the second housing) is greater than or equal to 120° and less than 180°, which can be correspondingly converted to the angle between the first display unit and the second display unit (or, it can also be understood as the angle between the first housing and the second housing) being greater than 0° and less than or equal to 60°.

[0026] In conjunction with the first aspect, in some implementations of the first aspect, based on the watch body being in a first state, the distance between the first housing and the second housing along the flexible display screen is L1; based on the watch body being in a second state, the distance between the first housing and the second housing along the flexible display screen is L2, satisfying: |L1-L2|≤0.1mm.

[0027] According to the embodiments of this application, both the first state and the second state can be understood as any state in which the watch body is located. For example, the first state can be an unfolded state, and the second state can be a folded state. When the watch body is in the first state and the second state, the distance between the first shell and the second shell along the flexible display screen is approximately the same, so that the flexible display screen will not be stretched or squeezed during the folding process of the watch body (in different states).

[0028] In conjunction with the first aspect, in some implementations of the first aspect, the watch body further includes a battery located in the first housing.

[0029] In conjunction with the first aspect, in some implementations of the first aspect, the watch body further includes a motor and / or a microphone, the motor and / or microphone being located in the second housing.

[0030] According to embodiments of this application, the watch body may also include other components, such as printed circuit boards. Components can be located within corresponding housings according to actual production or design requirements. Different components can be electrically connected via flexible printed circuit boards.

[0031] In conjunction with the first aspect, in some implementations of the first aspect, the thickness of the first housing is less than or equal to 8 mm, and / or the thickness of the second housing is less than or equal to 8 mm.

[0032] According to the embodiments of this application, since the watch body includes multiple housings, the components inside the watch body can be located in different housings, thereby reducing the thickness of the watch body and improving the comfort of the user wearing the wearable device.

[0033] In conjunction with the first aspect, in some implementations of the first aspect, the housing further includes a third housing and a second hinge; wherein a first end of the second hinge is fixedly connected to the first housing, and a second end of the second hinge is fixedly connected to the third housing.

[0034] According to embodiments of this application, as the number of foldable portions of the watch body increases, the size of the flexible display screen can be further increased to provide a better user experience. In one embodiment, the third housing may also be fixedly connected to the first housing. The angle between the third housing and the first housing is fixed, and the first housing and the third housing cannot rotate relative to each other via a second hinge.

[0035] In conjunction with the first aspect, in some implementations of the first aspect, the second housing is rotatable toward a first side of the first housing via the first hinge, and the third housing is rotatable toward a first side of the first housing via the second hinge.

[0036] According to the embodiments of this application, the two ends of the first housing are rotatably connected to the second housing and the third housing, respectively, so that when the user wears the wearable device, it can better fit the user's wrist and improve the user's wearing comfort.

[0037] In a second aspect, a wearable device is provided, the wearable device comprising a watch body as described in any one of the first aspects, and a watch strap, the watch strap being rotatably or fixedly connected to the watch body. Attached Figure Description

[0059] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0060] It should be noted that, in the description of the embodiments of this application, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. The "and / or" in this article is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone.

[0061] In the embodiments of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more, and "at least one" and "one or more" refer to one, two, or more than two. The singular expressions "a," "an," "the," "the," "this," and "this" are intended to also include expressions such as "one or more," unless the context explicitly indicates otherwise.

[0062] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0063] In the description of the embodiments of this application, the terms "upper," "lower," "inner," "outer," "vertical," and "horizontal," etc., indicate orientations or positional relationships relative to the indicated placement of components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and not to indicate or imply a specific orientation that the device or component must have, or its construction and operation in a specific orientation. They can change accordingly depending on the orientation of the components in the accompanying drawings, and therefore should not be construed as limiting this application. Furthermore, "vertical" in this application is not strictly vertical, but within the allowable error range. "Parallel" is not strictly parallel, but within the allowable error range.

[0064] In the embodiments of this application, the same reference numerals are used to denote the same component or part. For the same part in the embodiments of this application, only one part or component may be labeled with reference numerals in the figures. It should be understood that the reference numerals also apply to other identical parts or components. In addition, the various parts in the figures are not drawn to actual scale, and the dimensions and sizes of the parts shown in the figures are only exemplary and should not be construed as limiting this application.

[0065] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installed," "connected," "set in," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0066] Figure 1 This is a schematic diagram of a wearable device 10 provided in an embodiment of this application.

[0067] like Figure 1 As shown, the wearable device 10 can be a wristband or a watch. In one embodiment, the wearable device 10 may include a watch body 13, a watch strap 20, a watch band 30, and a watch buckle 16.

[0068] The two sides of the watch body 13 can be rotatably or fixedly connected to the watch strap 20 and the watch strap 30, respectively. The buckle 16 can be located at the end of the watch strap 20 or the watch strap 30 away from the watch body 13 (the end not connected to the watch body 13). When the user wears the wearable device 10, the buckle 16 can be used to connect the watch strap 20 and the watch strap 30 to each other.

[0069] In one embodiment, the watch body 13 may include components such as a housing and a display screen. In some scenarios, the housing may also be referred to as the mid-frame of the watch body 13. The display screen may be located on a first side of the housing and fixedly connected to the housing. The first side of the housing can be understood as the side away from the user's wrist when the user wears the wearable device 10. The housing and the display screen may form a receiving cavity, which may be used to place related components such as circuit boards (not shown in the figure).

[0070] The circuit board and related components may include a printed circuit board (PCB), a processor electrically connected (coupled) to the PCB, and one or more sensors. The processor can be used to control these sensors to perform measurement and detection operations, and the processor can also be used to process the detection results from the sensors.

[0071] For example, the aforementioned sensor may include one or more of the following: photoplethysmograph (PPG) sensor, barometric pressure sensor, fingerprint sensor, electrocardiogram (ECG) sensor, acceleration (ACC) sensor, ambient light sensor, proximity sensor, touch sensor, temperature sensor, gyroscope sensor, etc.

[0072] The PPG sensor can be used to detect heart rate, i.e., the number of heartbeats per unit time. The barometric pressure sensor can be used to detect the pressure value between the human body and the wearable device 10. The ECG sensor can be used to detect the capacitance between the human body and the wearable device 10, which can be used for ECG detection. The ACC sensor can be used to detect the magnitude of the acceleration of the wearable device 10 in various directions (generally three axes, i.e., x, y, and z axes). The value of this acceleration can be used to identify the posture of the wearable device 10 and for applications such as pedometers. The gyroscope sensor can be used to determine the motion posture of the wearable device 10. For example, the gyroscope sensor can determine the angular velocity of the wearable device 10 around the three axes (i.e., x, y, and z axes), and these angular velocities can be used to reflect the user's motion state.

[0073] It should be understood that the above description of the sensors in the wearable device 10 is merely exemplary. In practical applications, the wearable device 10 may include more or fewer sensors, or other sensors with the same or similar functions may be used to replace the sensors listed above. This application embodiment does not limit the scope of the invention.

[0074] In one embodiment, the cavity enclosed by the housing and the display screen can also be used to house a power supply circuit, which can be used to power electronic components (such as processing units and various sensors) in the wearable device 10. Exemplarily, the power supply circuit may include a battery.

[0075] In one embodiment, the watch strap 20 and watch strap 30 can be rotatably connected to the watch body 13 in various ways, including but not limited to: spring bar interface connection, fixed bar interface connection, hook connection, magnetic connection or threaded connection, etc. For the sake of brevity, they will not be described in detail.

[0076] It should be understood that the above embodiments are described using the example of detachable straps 20 and 30 to the watch body 13. In actual production or design, straps 20 and 30 can be fixedly connected to the watch body 13 (straps 20 and 30 are not detachable from the watch body 13). The connection method between the watch body and strap is not limited in this application embodiment and can be determined according to actual production or design. For the sake of brevity, it will not be elaborated further.

[0077] In one embodiment, the wearable device 10 includes accessories. For example, accessory 40 may include an airbag for blood pressure detection, accessory 40 may also include external electrode pads for electrocardiogram detection, or accessory 40 may include sensors for ultraviolet light intensity, light intensity detection, etc., and this application does not limit this.

[0078] In one embodiment, accessory 40 may be fixedly connected to watch strap 20 or watch strap 30.

[0079] In one embodiment, the buckle 16 may include one or more of the following: a pin buckle, a folding buckle, a butterfly buckle, or a concealed buckle.

[0080] Figure 2 This is a schematic diagram of a usage scenario for a wearable device 10 provided in an embodiment of this application.

[0081] like Figure 2 As shown, when a user wears wearable device 10, the small display screen causes numerous inconveniences. Increasing the display size, however, increases the gap between the wearable device and the user's wrist due to the wearing method, leading to further discomfort. Therefore, how to increase the display size of wearable devices while ensuring user comfort is a pressing issue that needs to be addressed.

[0082] This application provides a watch body and a wearable device. The watch body includes a housing and a flexible display screen. The flexible display screen and the housing are fixedly connected. The housing includes a first housing and a second housing that can rotate relative to the first housing. The flexible display screen can bend relative to the housing as it rotates, thereby making it more comfortable for the user to wear even with a larger display size, thus improving the user experience.

[0083] Figure 3 This is a schematic diagram of a table body 13 provided in an embodiment of this application.

[0084] It should be understood that Figure 3 The table body 13 shown in the subsequent figures can also be applied to Figure 1 For the sake of brevity, the wearable devices 10 shown will not be described in detail.

[0085] like Figure 3 As shown, the watch body 13 includes a flexible display screen 110 and a housing 120.

[0086] The flexible display screen 110 and the housing 120 are fixedly connected.

[0087] The housing 120 includes a first housing 121, a second housing 122, and a first hinge 124.

[0088] The first hinge 124 includes a first link 1241, a second link 1242, and a third link 1243, as follows: Figure 4 As shown. The first end of the first link 1241 is fixedly connected to the first housing 121. The second end of the first link 1241 is slidably connected to the first end of the second link 1242. The second end of the second link 1242 is slidably connected to the first end of the third link 1243. The second end of the third link 1243 is fixedly connected to the second housing 122.

[0089] It should be understood that, in one embodiment, the sliding connection between the first link 1241 and the second link 1242 can be understood as the first link 1241 and the second link 1242 being directly slidably connected, without any other components between them. In another embodiment, the sliding connection between the first link 1241 and the second link 1242 can also be understood as the first link 1241 and the second link 1242 being slidably connected through other components (e.g., other links). The sliding connection between any two links in the embodiments of this application can be understood accordingly, and for the sake of brevity, it will not be elaborated further.

[0090] In one embodiment, the first hinge 124 may further include a fourth link 1244 and a fifth link 1245.

[0091] It should be understood that in this embodiment, the example is that the first link 1241 and the second link 1242 are directly slidably connected, and the second link 1242 and the third link 1243 are slidably connected through the fourth link 1244 and the fifth link 1245. In actual production or design, corresponding adjustments can be made, for example, including more links or fewer links. This embodiment does not limit this.

[0092] According to an embodiment of this application, the housing 120 includes a first housing 121 and a second housing 122 that are rotatable relative to each other via a first hinge 124. Since the flexible display screen 110 is fixedly connected to the housing 120, the flexible display screen 110 can also bend with the relative rotation of the first housing 121 and the second housing 122. Therefore, when a user wears the wearable device, the watch body 13 can be in a folded or partially folded state, making the watch body fit the user's watch more closely and greatly improving the user's wearing comfort. Simultaneously, when the watch body 13 is in a partially folded or unfolded state, the watch body has a larger display screen, thus providing a better user experience.

[0093] In one embodiment, the flexible display screen 110 may include a first display portion 111 corresponding to the first housing 121, a second display portion 112 corresponding to the second housing 122, and a first foldable display portion 114 corresponding to the first hinge 124. The first foldable display portion 114 may be connected between the first display portion 111 and the second display portion 112.

[0094] It should be understood that when the watch body 13 in the above embodiments is in an unfolded state (or flattened state), it can be understood that the first housing 121 and the second housing 122 are in an unfolded state, or that the first display part 111 corresponding to the first housing 121 and the second display part 112 corresponding to the second housing 122 are in an unfolded state, such as... Figure 5 As shown.

[0095] In this context, the first housing 121 and the second housing 122 being in the unfolded state can be understood as the angle between the first housing 121 and the second housing 122 being 180°. At this time, the first housing 121 and the second housing 122 can be considered to be located on the same plane.

[0096] When the flexible display screen 110 is in its unfolded state, it can be understood that the angle between the first display unit 111 corresponding to the first housing 121 and the second display unit 112 corresponding to the second housing 122 is 180 degrees. At this time, the first display unit 111 and the second display unit 112 can be considered to be located on the same plane.

[0097] Alternatively, with the body 13 in its unfolded state (or flattened state), it can be understood that the first link 1241, the second link 1242, and the third link 1243 are in their unfolded state. The angle between the first link 1241, the second link 1242, and the third link 1243 is 180° (which can be understood as the relative sliding change between the first link 1241, the second link 1242, and the third link 1243 being minimal). At this time, the first link 1241, the second link 1242, and the third link 1243 can be considered to be located on the same plane.

[0098] It should be understood that due to possible errors in engineering implementation, when the angle between the first display unit 111 and the second display unit 112, or the angle between the first housing 121 and the second housing 122, is between 170° and 190°, the watch body 13 can be considered to be in a flattened state.

[0099] In this embodiment of the application, the watch body 13 being in a folded state can mean that the watch body 13 is currently bent, and the degree of bending of the watch body 13 has reached its maximum (or, it can also be understood as the relative sliding change between the first link 1241, the second link 1242, and the third link 1243 in the first hinge being the maximum), such as Figure 6 As shown. At this time, the first housing 121 and the second housing 122 can be considered to be located on different planes, or they can be considered to be at the smallest angle between the first display unit 111 and the second display unit 112 (an obtuse angle between the first display unit 111 and the second display unit 112). The first display unit 111 and the second display unit 112 can be considered to be located on different planes, and the angle between the first display unit 111 and the second display unit 112 is the smallest.

[0100] Combination Figure 5 and Figure 6 The wearable device 10 can switch between a folded state and an unfolded state (or, it can be understood as the relative sliding change between the first link 1241, the second link 1242, and the third link 1243 in the first hinge changing from maximum to minimum). When the wearable device 10 is in the folded state, it fits the user's wrist more closely; when the wearable device 10 is in the unfolded state, it can display a relatively large screen to increase the user's viewing range. It should be understood that when the wearable device 10 switches from the folded state to the unfolded state, the intermediate process can be understood as the wearable device 10 being in a partially folded state (or a floating state). During the switching process, the area of ​​the wearable device 10 projected in the direction perpendicular to the flexible display increases (or, it can be understood as the area of ​​the wearable device 10 projected onto the ground increases), and the screen area increases.

[0101] In one embodiment, the watch body 13 is in a folded state, and the angle between the first display portion 111 and the second display portion 112 (or, it can also be understood as the angle between the first housing 121 and the second housing 122) is greater than or equal to 100° and less than 180°. In another embodiment, the watch body 13 is in a folded state, and the angle between the first display portion 111 and the second display portion 112 (or, it can also be understood as the angle between the first housing 121 and the second housing 122) is greater than or equal to 120° and less than 180°.

[0102] It should be understood that, for the sake of brevity, in this embodiment, only the angle between the first housing 121 and the second housing 122 (or, it can also be understood as the angle between the first housing 121 and the second housing 122) is described as an obtuse angle. Due to the complementary nature of angles, this angle can also be converted to an acute angle. For example, the angle between the first display unit 111 and the second display unit 112 (the angle between the first housing 121 and the second housing 122) being greater than or equal to 120° and less than 180° can be correspondingly converted to the angle between the first display unit 111 and the second display unit 112 (or, it can also be understood as the angle between the first housing 121 and the second housing 122) being greater than 0° and less than or equal to 60°.

[0103] It should be understood that the folded state of the wearable device 10 described in this application embodiment is different from the folded state of other foldable electronic devices (e.g., multi-fold mobile phones).

[0104] For example, when other foldable electronic devices (e.g., including two housings) are folded outwards, at least a portion of the first and second housings are housed within the space enclosed by the flexible display screen, with the first display unit, the first housing, the second housing, and the second display unit stacked sequentially. Similarly, the first and second display units can be approximately parallel and spaced apart from each other. The distance between the first and second display units is relatively large.

[0105] When other foldable electronic devices (e.g., including two housings) are folded inwards, at least a portion of the flexible display screen is housed within the space enclosed by the first and second housings, with the first housing, first display unit, second display unit, and second housing stacked sequentially. Similarly, the first and second display units can be approximately parallel, spaced apart, or closely fitted. The distance between the first and second display units is relatively short.

[0106] Therefore, for other foldable electronic devices, the change in angle between the first and second display units (or, as can be understood, the angle between the first and second housings) when switching from the unfolded state to the folded state is approximately 90°.

[0107] Regarding the wearable device 10 described in this embodiment, since the wearable device 10 needs to fit snugly against the user's wrist when worn, it enhances user comfort. When the wearable device 10 switches from an unfolded state to a folded state, the change in the angle between the first display section 111 and the second display section 112 (or, it can also be understood as the change in the angle between the first housing 121 and the second housing 122) is less than 90°. In the folded state, the first display section 111 and the second display section 112 are not parallel.

[0108] Furthermore, due to the small size of the wearable device 10, there is not a large space between the first housing 121 and the second housing 122 for setting up a pivot (the first hinge 124 described in this embodiment) with a complex structure. When the wearable device 10 switches from the unfolded state to the folded state, the rotation angle of the first display unit 111 and the second display unit 112 (or, it can also be understood as the first housing 121 and the second housing 122) is limited.

[0109] In one embodiment, the watch body 13 may further include a third housing 123. In one embodiment, the third housing 123 may correspond to the third display portion 113 of the flexible display screen 110.

[0110] In one embodiment, the third housing 123 may be substantially the same as the second housing 122, for example, their dimensions may be the same. In another embodiment, the third housing 123 may also differ from the second housing 122, depending on actual production or design requirements.

[0111] It should be understood that as the number of foldable portions in the watch body 13 increases, the size of the flexible display 110 can be further increased to provide a better user experience.

[0112] In one embodiment, the third housing 123 is fixedly connected to the first housing 121. The angle between the third housing 123 and the first housing 121 is fixed, and the first housing 121 and the third housing 123 cannot rotate relative to each other via the second hinge 125.

[0113] In one embodiment, the watch body 13 may further include a second hinge 125. A first end of the second hinge 125 is fixedly connected to a first housing 121, and a second end is fixedly connected to a third housing 123. The first housing 121 and the third housing 123 are rotatable relative to each other via the second hinge 125.

[0114] In one embodiment, the second hinge 125 is similar to the first hinge 124 in this application embodiment. For example, the number of links in the second hinge 125 can be the same as the number of links in the first hinge 124. Alternatively, the number of links in the second hinge 125 can be different from the number of links in the first hinge 124, which can be determined according to actual production or design, and this application embodiment does not impose any limitations on this. The connection method between the links in the second hinge 125 can be understood by referring to the connection method between the links in the first link 124. For the sake of brevity, in this application embodiment, only the first hinge 124 is used as an example for description, and the structure of the second hinge 125 will not be described in detail.

[0115] In one embodiment, the second hinge 125 may correspond to the second foldable display portion 115 of the flexible display 110. The second foldable display portion 114 may be connected between the second display portion 112 and the third display portion 113.

[0116] In one embodiment, the second housing 122 is rotatable toward the first side of the first housing 121 via the first hinge 124, and the third housing 123 is rotatable toward the first side of the first housing 121 via the second hinge 125. The first side of the first housing 121 can be understood as the side facing the user's wrist when the user is wearing the wearable device.

[0117] It should be understood that the two ends of the first housing 121 are rotatably connected to the second housing 122 and the third housing 123 respectively, so that when the user wears the wearable device 10, it can fit the user's wrist better and improve the user's wearing comfort.

[0118] In one embodiment, the body 13 may further include a first nut 201a, such as Figure 3 As shown. The first connecting rod 1241 includes a first screw hole 201b, as... Figure 4 As shown. The first nut 201a passes through the first screw hole 201b and is fixedly connected to the first housing 121.

[0119] It should be understood that the body 13 may include a plurality of first nuts 201a, and the first connecting rod 1241 may include a plurality of corresponding first screw holes 201b to enhance the fixed connection strength between the first connecting rod 1241 and the first housing 121. The number of first nuts 201a can be determined according to actual production or design, and for the sake of brevity, they will not be described in detail.

[0120] Similarly, the third link 1243 can also be fixedly connected to the second housing 122 via the second nut 202a and the second screw hole 202b. The second hinge 125 can also be fixedly connected to the first housing 121 and the third housing 123 via the third nut 203a and the fourth nut 204a, respectively.

[0121] In this embodiment, only the method of using a nut and a screw hole is used as an example. In actual production or design, other methods can also be used for fixing, and this embodiment does not limit this. For example, the first connecting rod 1241 and the first housing 121 can be connected by a snap-fit, or by adhesive, etc.

[0122] In one embodiment, the first link 1241 and the second link 1242 are respectively provided with a first sliding block 211a and a first receiving groove 211b, such as Figure 7 As shown. At least a portion of the first sliding block 211a is located within the first receiving groove 211b and is slidably connected to the first receiving groove 211b.

[0123] It should be understood that the first link 1241 and the second link 1242 are slidably connected by the first sliding block 211a and the first receiving groove 211b. When the first housing 121 and the second housing 122 rotate relative to each other, the first sliding block 211a slides within the first receiving groove 211b.

[0124] Figures 8 to 10 The diagrams show cross-sectional views of the watch body 13 along line A-A' when it is in a folded state, a partially folded state, and an unfolded state. Figures 8 to 10 As shown, during the process of the watch body 13 changing from a folded state through a partially folded state to an unfolded state, the portion of the first sliding block 211a within the first receiving groove 211b gradually decreases.

[0125] For the sake of brevity, this embodiment of the application only uses the structure of the first link 1241 including the first sliding block 211a and the second link 1242 including the first receiving groove 211b as an example for explanation. In actual production or design, the structure of the first link 1241 including the first receiving groove 211b and the second link 1242 including the first sliding block 211a can also be used. Both structures have the same technical effect and will not be described in detail.

[0126] The change in relative sliding between the links described in the above embodiments can be understood as the portion of the sliding block between two adjacent links that is located within the corresponding receiving groove. During the process of the wearable device 10 switching between a folded state and an unfolded state, the change in relative sliding between two adjacent links changes from maximum to minimum (the portion of the sliding block within the receiving groove gradually decreases).

[0127] In one embodiment, the second link 1242 may include a first receiving groove 211b and a second sliding block. The second link 1242 is slidably connected to the first link 1241 via the first receiving groove 211b. The second link 1242 is slidably connected to the third link 1243 via the second sliding block. In another embodiment, the second sliding block is slidably connected to the third link 1243 via another link.

[0128] It should be understood that in this embodiment, the second link 1242 is described using the example of a structure that includes both a sliding block and a receiving groove. In actual production or design, other structures can also be used, and for the sake of brevity, they will not be elaborated upon. For example, the second link 1242 may include a first receiving groove 211b and a second receiving groove, with the second link 1242 slidably connected to the first link 1241 via the first receiving groove 211b. The second link 1242 is slidably connected to the third link 1243 via the second receiving groove. Alternatively, the second link 1242 may include a first sliding block 211a and a second sliding block, with the second link 1242 slidably connected to the first link 1241 via the first sliding block 211a. The second link 1242 is slidably connected to the third link 1243 via the second sliding block. Correspondingly, the first link 1241 and the third link 1243 can also be configured according to the structure of the second link 1242.

[0129] Similarly, when the first hinge 124 includes more links, the links can have the same or different structures. For the sake of brevity, in the embodiments of this application, the second link 1242, the fourth link 1244, and the fifth link 1245 have the same structure. The second link 1242 is slidably connected to the third link 1243 through the fourth link 1244 and the fifth link 1245. In actual production or design, the second link 1242, the fourth link 1244, and the fifth link 1245 can have different structures, which will not be described in detail here.

[0130] In one embodiment, the cross-section of the first receiving groove 211b along the first direction is arc-shaped. The virtual center O1 of the first receiving groove 211b is located on the flexible display screen 110, such as... Figure 11 As shown. The first direction is the direction from the first housing 121 to the second housing 122.

[0131] It should be understood that the virtual center O1 of the first receiving groove 211b can be understood as the virtual center O1 of the area overlapping with the first sliding block 211a in the cross-section of the first receiving groove 211b along the first direction when the body 13 is in the folded state. For example, the virtual center O1 of the first receiving groove 211b can be understood as the virtual center O1 of the arc surface on one side of the area overlapping with the first sliding block 211a in the cross-section of the first receiving groove 211b along the first direction. In one embodiment, the part of the first receiving groove 211b that does not overlap with the first sliding block 211a in the cross-section along the first direction can be of any shape, for example, it can be rectangular, arc-shaped, or irregular in shape, etc. For the sake of brevity, the virtual centers of the receiving grooves described in the embodiments of this application can all be understood accordingly, and will not be described in detail here.

[0132] The fact that the cross-section of the first receiving groove 211b along the first direction is arc-shaped can also be understood as the fact that the cross-section of the first sliding block 211a along the first direction is arc-shaped. Correspondingly, the virtual center O1 of the first sliding block 211a is located on the flexible display screen 110. For the sake of brevity, the sliding blocks described in the embodiments of this application can all be understood accordingly.

[0133] In one embodiment, the first hinge 124 includes a plurality of receiving slots. For example, the first hinge 124 includes a second receiving slot 212b, a third receiving slot 213b, and a fourth receiving slot 214b, such as... Figure 11 As shown.

[0134] The second receiving groove 212b has an arc-shaped cross-section in the first direction, and its virtual center O2 is located on the flexible display screen 110. The third receiving groove 213b has an arc-shaped cross-section in the first direction, and its virtual center O3 is located on the flexible display screen 110. The fourth receiving groove 214b has an arc-shaped cross-section in the first direction, and its virtual center O4 is located on the flexible display screen 110.

[0135] It should be understood that when the virtual centers of the multiple receiving slots are all located on the flexible display screen 110, the first housing 121 and the second housing 122 rotate relative to each other, and the rotation angles of the multiple connecting rods are approximately the same. Since the rotation angles of the multiple connecting rods are approximately the same, when the watch body 13 is in the first state and the second state, the distance between the first housing 121 and the second housing 122 along the flexible display screen 110 is approximately the same, and the watch body 13 pulls or squeezes the flexible display screen 110 during the folding process (in different states).

[0136] Here, both the first state and the second state can be understood as any state that the table body 13 is in. For example, the first state can be the unfolded state, such as... Figure 12As shown. In the first state, the distance between the first housing 121 and the second housing 122 along the flexible display screen 110 is L1. The second state can be a folded state, such as... Figure 13 As shown. When the watch body 13 is in the second state, the distance between the first housing 121 and the second housing 122 along the flexible display screen 110 is L2. L1 and L2 are approximately the same, which can be understood as L1 and L2 satisfying: |L1-L2|≤0.1mm, so that the flexible display screen 110 will not be stretched or squeezed during the folding process of the watch body 13 (in different states).

[0137] Meanwhile, as the number of links included in the first hinge increases, the first housing 121 and the second housing 122 rotate relative to each other, and the rotation angle of the multiple links becomes more uniform.

[0138] In one embodiment, the virtual center O1 of the first receiving slot 211b is located on any layer of the flexible display screen 110. For example, the virtual center O1 of the first receiving slot 211b is located on the neutral layer of the flexible display screen 110.

[0139] In one embodiment, the virtual center O1 of the first receiving groove 211b, the virtual center O2 of the second receiving groove 212b, the virtual center O3 of the third receiving groove 213b, and the virtual center O4 of the fourth receiving groove 214b are located on the same layer of the flexible display screen 110. In another embodiment, the virtual centers O1, O2, O3, and O4 are all located at the thickness center of the flexible display screen 110. In yet another embodiment, the virtual centers O1, O2, O3, and O4 are all located on the neutral layer of the flexible display screen 110.

[0140] It should be understood that the virtual centers of the multiple receiving slots are all located on the same layer of the flexible display screen 110, which can prevent this layer of the flexible display screen from being stretched or squeezed during the folding process of the body 13.

[0141] In one embodiment, when the watch body 13 is in a folded state, the angle between the bisectors of any two adjacent links in the first hinge 124 is the same as the angle between the adjacent bisectors. Figure 13 As shown. For example, among the first, second, third, and fourth bisectors, the angle α1 between the first and second bisectors, the angle α2 between the second and third bisectors, and the angle α3 between the third and fourth bisectors are the same.

[0142] In the embodiments of this application, the thickness can be understood as the dimension of the watch body 13 in the second direction when it is in the unfolded state. The second direction is the direction perpendicular to the flexible display screen 110 when the watch body 13 is in the unfolded state.

[0143] It should be understood that when the watch body 13 is in a folded state, the angles between adjacent bisectors are the same, the first housing 121 and the second housing 122 rotate relative to each other, and the rotation angles of the multiple links are approximately the same. Since the rotation angles of the multiple links are approximately the same, when the watch body 13 is in the first state and the second state, the distance between the first housing 121 and the second housing 122 along the flexible display screen 110 is approximately the same, thereby preventing the flexible display screen 110 from being stretched or squeezed during the folding process of the watch body 13 (in different states).

[0144] In the above embodiments, the dividing line can be understood as a virtual straight line that is perpendicular to the flexible display screen 110 and is equidistant from the connecting rods on both sides.

[0145] In one embodiment, the body 13 may further include a support layer 130, such as Figure 14 As shown. The support layer 130 is located between the flexible display screen 110 and the housing 120. The support layer 130 is fixedly connected to the flexible display screen 110. The support layer 130 is fixedly connected to the housing 120. In one embodiment, the support layer 130 is fixedly connected by adhesive.

[0146] It should be understood that the support layer 130 can be used to support the flexible display screen 110, thereby isolating the flexible display screen 110 from the components or parts disposed within the housing 120 to avoid damage to the flexible display screen 110.

[0147] In one embodiment, the support layer 130 may include a first support portion 131, a second support portion 132, and a first flexible support portion 134, such as... Figure 15 As shown.

[0148] The first flexible support portion 134 is located between the first support portion 131 and the second support portion 132. A first end of the first flexible support portion 134 is fixedly connected to the first support portion 131, and a second end is fixedly connected to the second support portion 132. The first support portion 131 and the second support portion 132 can rotate relative to each other via the first flexible support portion 134.

[0149] The first support portion 131 is fixedly connected to the first housing 121. The second support portion 132 is fixedly connected to the second housing 122. The first flexible support portion 134 is fixedly connected to the first hinge 124.

[0150] It should be understood that the first flexible support part 134 is fixedly connected to the first hinge 124. During the rotation of the first hinge 124, since the first flexible support part 134 can be bent, it can rotate together with the first hinge 124 to provide better support for the flexible display screen 110.

[0151] In one embodiment, the first flexible support portion 134 includes a first support rod 1341 and a first flexible substrate 1345, such as Figure 16 As shown. The first support rod 1341 is fixedly connected to the first flexible substrate 1345. In one embodiment, the fixed connection between the first support rod 1341 and the first flexible substrate 1345 can be achieved by casting a flexible material onto the first support rod 1341, and the cast flexible material can form the first flexible substrate 1345.

[0152] In one embodiment, the second connecting rod 1242 includes a first adhesive surface 221. The first adhesive surface 221 is fixedly connected to the first support rod 1341. In one embodiment, the first adhesive surface 221 and the first support rod 1341 are fixedly connected by adhesive.

[0153] It should be understood that when the first hinge 124 includes N links, the N links may include N-1 adhesive surfaces corresponding to different support rods. This can be understood as each of the N-1 links including one adhesive surface, with each adhesive surface used for fixed connection with its corresponding support rod. Alternatively, it can be understood that some of the N links include two adhesive surfaces, while others do not, and so on.

[0154] Correspondingly, the first flexible support portion 134 includes N-1 support rods, with each support rod corresponding to a bonding surface to achieve a fixed connection between the first flexible support portion 134 and the first hinge 124. For the sake of brevity, in this embodiment, only the first hinge 124 comprising a first connecting rod 1241, a second connecting rod 1242, a third connecting rod 1243, a fourth connecting rod 1244, and a fifth connecting rod 1245 is used as an example. Correspondingly, the first flexible support portion 134 includes only the first support rod 1341, the second support rod 1342, the third support rod 1343, and the fourth support rod 1344. In actual production or design, more or fewer connecting rods and corresponding support rods may be included, and this embodiment does not impose any limitations on this.

[0155] For the sake of brevity, in this embodiment, only the first link 1241 does not include a bonding surface, while all other links include a bonding surface (for example, the second link 1242, the third link 1243, the fourth link 1244, and the fifth link 1245 include a first bonding surface 221, a second bonding surface 222, a third bonding surface 223, and a fourth bonding surface 224, respectively). In actual production or design, adjustments can be made, and this embodiment does not impose any limitations on this.

[0156] In one embodiment, the second link 1242 may include a plurality of first adhesive surfaces 221 to enhance the strength of the fixed connection between the second link 1242 and the first support rod 1341.

[0157] It should be understood that, in the embodiments of this application, the number of adhesive surfaces fixedly connected to the same support rod is not limited, and can be adjusted according to actual production or design.

[0158] In one embodiment, the first adhesive surface 221 and the first support rod 1341 are respectively provided with a first positioning post 221a and a first positioning hole 221b, such as Figures 16 to 18 As shown. At least a portion of the first positioning post 221a is located in the first positioning hole 221b, as... Figure 19 As shown.

[0159] It should be understood that during the assembly of the body 13, the first positioning post 221a and the first positioning hole 221b can be used for positioning between the first adhesive surface 221 and the first support rod 1341, thereby improving the accuracy of the first hinge 124 and the first flexible support part 134 during the assembly process.

[0160] In one embodiment, the first adhesive surface 221 and the first support rod 1341 are respectively provided with a plurality of first positioning posts 221a and first positioning holes 221b, and the first positioning posts 221a and the first positioning holes 221b correspond one-to-one to improve the positioning accuracy between the first adhesive surface 221 and the first support rod 1341.

[0161] It should be understood that, for the sake of brevity, this embodiment only uses the example of the first positioning post 221a being located on the first adhesive surface 221 and the first positioning hole 221b being located on the first support rod 1341. In actual production or design, the first positioning post 221a may also be located on the first support rod 1341 and the first positioning hole 221b may also be located on the first adhesive surface 221. This embodiment does not impose any restrictions on this, and will not be elaborated further.

[0162] When the first hinge 124 includes multiple adhesive surfaces and the first flexible support 134 includes multiple support rods corresponding to the adhesive surfaces, some of the multiple adhesive surfaces may include positioning posts (the corresponding support rods include positioning holes), and other parts may include positioning holes (the corresponding support rods include positioning holes). This application embodiment does not limit this, and will not elaborate further.

[0163] It should be understood that when the watch body 13 also includes a third housing 123, the support layer 130 may include a third support portion 133. The third support portion 133 is fixedly connected to the third housing.

[0164] When the watch body 13 further includes a second hinge 125, the support layer 130 may also include a second flexible support portion 135. The second flexible support portion 135 is located between the first support portion 131 and the third support portion 133. A first end of the second flexible support portion 135 is fixedly connected to the first support portion 131, and a second end is fixedly connected to the third support portion 133. The first support portion 131 and the third support portion 133 can rotate relative to each other through the second flexible support portion 135. The second flexible support portion 135 is fixedly connected to the second hinge 125.

[0165] The second flexible support portion 135 has a similar structure to the first flexible support portion 134. In one embodiment, the second flexible support portion 135 has the same structure as the first flexible support portion 134, and the second flexible support portion 135 includes a fifth support rod 1351, a sixth support rod 1352, a seventh support rod 1353, an eighth support rod 1354, and a second flexible substrate 1355. For the sake of brevity, in the following embodiments, only the first flexible support portion 134 is described as an example, and the second flexible support portion 135 can be understood accordingly. For the sake of brevity, it will not be described in detail.

[0166] In one embodiment, the watch body 13 further includes a battery 140. The battery 140 is located within the first housing 121, as shown below. Figure 20 As shown. In one embodiment, the battery 140 is located within the space enclosed by the first housing 121 and the flexible display screen 110.

[0167] In one embodiment, the watch body 13 may include a motor 141 and / or a microphone 142. The motor 141 and / or microphone 142 are located within the second housing 122, as shown below. Figure 20 As shown. In one embodiment, the motor 141 and / or the microphone 142 are located within the space enclosed by the second housing 122 and the flexible display screen 110.

[0168] In one embodiment, the body 13 may also be PPG 143, such as Figure 21 As shown, PPG143 can be located on the side of the first housing 121 away from the flexible display 110. When a user wears the wearable device, PPG143 can be used to monitor the user's health data.
