Description

Technical Field

[0001] This application belongs to the field of electronic device technology, specifically relating to a wearable device. Background Technology

[0002] With technological advancements, intelligent electronic devices have diversified, including common items like smartphones, tablets, smartwatches, and headphones, as well as the relatively niche smart glasses. Taking smartwatches as an example, their user base has gradually expanded as their functions have become more sophisticated. Currently, smartwatches typically have round or rectangular dials, and to provide a comfortable wearing experience, the dial size is usually relatively small. This results in a relatively small display area, making it more difficult for users to view complex or lengthy information. Summary of the Invention

[0003] The purpose of this application is to provide a wearable device to solve the problem that the display area of ​​current wearable devices is relatively small, which makes it difficult for users to view relatively complex or numerous display information.

[0004] This application discloses a wearable device, which includes a watch body and a screen assembly. The watch body has a receiving cavity, and the screen assembly is disposed in the receiving cavity. The watch body has an opening for the screen assembly to extend out of or be received in the receiving cavity.

[0005] When the screen assembly is in the retracted state, the screen assembly is housed within the receiving cavity;

[0006] When the screen assembly is in the extended state, the screen assembly extends out of the receiving cavity. The screen assembly includes a rollable screen and a first driving mechanism, which is used to drive the rollable screen to switch between a rolled-up state and an unfolded state.

[0007] This application discloses a wearable device including a watch body and a screen assembly. The screen assembly has a rollable screen mounted on a first driving mechanism, enabling the first driving mechanism to switch the rollable screen between a rolled-up state and an unfolded state. The screen assembly can be housed within a cavity of the watch body, and can also extend from an opening in the watch body out of the cavity. This allows the screen assembly to have both a retracted and an extended state, and when in the extended state, it can switch between the rolled-up and unfolded states. In the retracted state, the screen assembly is located within the cavity, ensuring the entire wearable device has a relatively small size for easy wearing. When the screen assembly switches from the retracted to the extended state, it extends out of the cavity, preparing for switching between the rolled-up and unfolded states. When the screen assembly switches to the unfolded state, the rollable screen is unfolded, allowing the exposed display area to provide a display function. This allows the entire wearable device to have a relatively large display area when needed, facilitating the viewing of complex or numerous display information. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0021] This application discloses a wearable device, which can be specifically a smart wearable device by being equipped with chips and other devices, such as a smartwatch. Figures 1-8As shown, the wearable device includes a watch body 107 and a screen assembly 106. Of course, wearable devices typically also include components such as a watch strap 101 and buttons 103. The watch strap 101 is connected to the watch body 107 so that the user can wear the device. The buttons 103 can be located on the outside of the watch body 107, and can be designed to have corresponding functions in different states. Furthermore, the wearable device disclosed in this application includes the aforementioned chip and is equipped with a battery and a display screen 105. The chip and battery are both installed inside the watch body 107. The display screen 105 and the chip are both connected to the battery. The display screen 105 is mounted on the watch body 107 and is exposed so that the user can obtain information such as time through the display screen 105.

[0022] The dial 111 is the basic structure of the wearable device. It can be made of materials with relatively high structural strength, such as plastic or metal. The shape of the dial 111 can be round, square, approximately round or approximately square, etc. The external dimensions of the dial 111 can be determined according to actual needs and are not limited here.

[0023] To increase the display area of ​​wearable devices in certain situations, as described above, the wearable device disclosed in this application includes a screen assembly 106. Furthermore, to accommodate the screen assembly 106 and ensure that it can extend from within the dial 111 to outside the dial 111, the dial 111 of the wearable device disclosed in this application has a receiving cavity and an opening, which are interconnected. The receiving cavity serves to accommodate the screen assembly 106, and the opening allows the screen assembly 106 to extend out or be received within the receiving cavity. Based on the above structure of the wearable device, the screen assembly 106 can be placed within the receiving cavity even when a relatively large display area is not required, such as in scenarios where the user typically wears the device, preventing a relatively large screen assembly 106 from adversely affecting the portability of the wearable device. Correspondingly, in situations where a relatively large display area is required, such as when users need to watch videos or relatively long text content, the screen assembly 106 can extend out of the receiving cavity through the opening, and the rollable screen 603 included in the screen assembly 106 can be unfolded outside the body 107 to provide a relatively larger display area.

[0024] Specifically, the volume and shape of the receiving cavity can be determined based on parameters such as the volume of the screen assembly 106 in the retracted state of the wearable device. This ensures that the receiving cavity can accommodate the retracted screen assembly 106 and allows the screen assembly 106 to move relative to the cavity wall, enabling switching between its position inside and outside the watch body 107. Correspondingly, the size and shape of the opening can also be determined based on the retracted screen assembly 106, ensuring that the retracted screen assembly 106 can extend out of the receiving cavity through the opening and retract into the receiving cavity through the opening.

[0025] As described above, the screen assembly 106 includes a rollable screen 603 and a first driving mechanism connected to the rollable screen 603, allowing the rollable screen 603 to be driven by the first driving mechanism, thereby switching the rollable screen between a rolled-up state and an unfolded state. Optionally, in a specific embodiment of this application, the first driving mechanism includes a first bracket 601 and a second bracket 602, which are movably connected. The first bracket 601 and the second bracket 602 can provide positioning for the sides of the rollable screen 603. Specifically, a first side of the rollable screen 603 is fixedly connected to the first bracket 601, and a second side of the rollable screen 603 is fixedly connected to the second bracket 602, thereby driving the rollable screen 603 to switch between a rolled-up state and an unfolded state during the relative movement of the first bracket 601 and the second bracket 602. Specifically, both the first bracket 601 and the second bracket 602 can be rod-shaped structural components, and the opposite first and second sides of the roll screen 603 can be fixed to the first bracket 601 and the second bracket 602 respectively by means of bonding; at the same time, in order to achieve the purpose of rolling up the roll screen 603, a winding method can be adopted to make the roll screen 603 roll up and rewound on at least one of the first bracket 601 and the second bracket 602.

[0026] More specifically, a portion of the rollable screen 603 can be wound onto the first bracket 601, and another portion can be wound onto the second bracket 602. This reduces the diameter of the rolled-up screen 603 in the wound state, thereby reducing the size of the receiving cavity and openings on the watch body 107. It also improves the winding and unwinding efficiency of the rollable screen 603. Specifically, the rollable screen 603 can be a rectangular structure. In another embodiment of this application, the watch body 107 can be a circular structure. Furthermore, the rollable screen 603 can be a fan-shaped structure, allowing it to be spliced ​​onto the outer periphery of the wearable device's display screen 105, increasing the overall integration of the wearable device's display surface and further enhancing the overall display effect.

[0027] As described above, the first bracket 601 and the second bracket 602 are movably connected. Specifically, the relative movement between the first bracket 601 and the second bracket 602 can be linear motion. In another embodiment of this application, the rollable screen 603 has a fan-shaped structure, so that the rollable screen 603 can be spliced ​​to the outside of the display screen 105 of the wearable device, so that the display screen 105 and the rollable screen 603 together form a display surface, improving the user's viewing experience. In this case, the first bracket 601 and the second bracket 602 can be rotated together. More specifically, when the first bracket 601 and the second bracket 602 are approximately regarded as linear rod-like structures, the extension lines of the first bracket 601 and the second bracket 602 intersect at the center of the watch body 107, and at least one of the first bracket 601 and the second bracket 602 can rotate relative to the watch body 107 with the center of the watch body 107 as the center.

[0028] Based on wearable devices with the above structure, more specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the screen assembly 106 has a retracted state and an extended state, and when the screen assembly 106 is in the extended state, the screen assembly 106 also has a rolled-up state and an unfolded state.

[0029] When the screen assembly 106 is in the retracted state, it is housed within the receiving cavity. In this state, the wearable device has a small size and high flexibility, making it easy for users to wear daily without significantly hindering their activities.

[0030] When the screen assembly 106 is in the extended state, it extends beyond the receiving cavity, ensuring that the cover 107 does not obstruct the deformation process of the screen assembly 106. Simultaneously, in this state, the first drive mechanism can drive the rollable screen 603 to switch between the rolled-up and unfolded states.

[0031] Meanwhile, when the screen assembly 106 is in the rolled-up state, the exposed display area of ​​the rollable screen 603 is the first area. Specifically, the first area is greater than or equal to zero, and in one specific embodiment of this application, the first area is equal to zero. This can maximize the reduction of the overall size of the screen assembly 106 in the rolled-up state, thereby reducing the size of the receiving cavity and the opening. Of course, if the structure of the first bracket 601 and the second bracket 602 limits the rollable screen 603 in the rolled-up state to the point that the exposed display area may not be zero, this also falls under the technical solution protected by this application.

[0032] When the screen assembly 106 is in the unfolded state, the display area exposed by the rollable screen 603 is the second area, which is larger than the first area. This ensures that the screen assembly 106 in the unfolded state has a relatively large display area, providing a better viewing experience for the user. Correspondingly, the relative movement between the first bracket 601 and the second bracket 602 allows the rollable screen 603 to switch between the rolled-up and unfolded states.

[0033] This application discloses a wearable device including a watch body 107 and a screen assembly 106. In the screen assembly 106, a rollable screen 603 is mounted on a first driving mechanism, enabling the first driving mechanism to drive the rollable screen 603 to switch between a rolled-up state and an unfolded state. Furthermore, the screen assembly 106 can be housed within a receiving cavity of the watch body 107, and the screen assembly 106 can also extend from an opening in the watch body 107 out of the receiving cavity. Thus, the screen assembly 106 has a retracted state and an extended state, and when the screen assembly 106 is in the extended state, it can switch between a rolled-up state and an unfolded state. When the screen assembly 106 is in the retracted state, it is located within the receiving cavity, ensuring that the entire wearable device has a relatively small size for easy wearing. When the screen assembly 106 switches from the retracted state to the extended state, it extends out of the receiving cavity of the body 107, preparing for the screen assembly 106 to switch between the retracted and extended states. When the screen assembly 106 switches to the extended state, the rollable screen 603 is unfolded, allowing the exposed display area of ​​the rollable screen 603 to provide a display function, so that when there is a corresponding need, the entire wearable device can have a relatively large display area, making it convenient for users to view relatively complex or numerous display information.

[0034] In the above embodiments, the screen assembly 106 can extend out of the receiving cavity from the opening and retract into the receiving cavity. Optionally, by providing a handle or other structure at the outer end of the screen assembly 106, the user can manually switch the screen assembly 106 between a retracted state inside the receiving cavity and an extended state outside the receiving cavity.

[0035] In another embodiment of this application, the wearable device further includes a second drive mechanism 102, which is mounted on the body 107 and the screen assembly 106 is connected to the second drive mechanism 102. The second drive mechanism 102 can drive the screen assembly 106 to move along the axial direction of the opening, and the screen assembly 106 can switch between a retracted state and a rolled-up state. This makes the switching of the screen assembly 106 between the aforementioned states automatic and reduces the probability of damage to the wearable device.

[0036] Specifically, the second drive mechanism 102 can be a linear drive device such as a linear motor. The second drive mechanism 102 is connected to the battery in the wearable device to ensure that the second drive mechanism 102 can work normally. At the same time, by mounting the drive seat of the second drive mechanism 102 on the watch body 107 and connecting the drive head of the second drive mechanism 102 to the screen assembly 106, when the second drive mechanism 102 is activated, the screen assembly 106 can be driven to extend and retract along the axial direction of the opening, and the screen assembly 106 can be switched between a position located inside the receiving cavity and a position extending outside the receiving cavity.

[0037] More specifically, when the screen assembly 106 switches from the retracted state to the extended state, the second drive mechanism 102 drives the screen assembly 106 to move from the inside to the outside along the axial direction of the opening, thereby driving the screen assembly 106 to extend out of the receiving cavity; when the screen assembly 106 switches from the extended state to the retracted state, the second drive mechanism 102 drives the screen assembly 106 to move from the outside to the inside along the axial direction of the opening, so that the screen assembly 106 can be gradually received back into the receiving cavity.

[0038] In another embodiment of this application, the second drive mechanism 102 is a rotation drive device, specifically a rotary motor, to improve the driving stability and driving accuracy of the second drive mechanism 102. In this case, the wearable device disclosed in this application embodiment may further include a transmission mechanism, and the second drive mechanism 102 is connected to the screen assembly 106 through the transmission mechanism.

[0039] Specifically, the transmission mechanism may include a gear and a rack. The gear may be mounted on the second drive mechanism 102, and the rack may be mounted on the screen assembly 106, so that when the second drive mechanism 102 drives the gear to rotate, the gear can drive the rack to move, thereby causing the screen assembly 106 to move relative to the body 107 along the axial direction of the opening.

[0040] To maximize the sealing performance of the wearable device, the transmission mechanism may optionally include a lead screw 108 and a lead screw nut 104. The lead screw 108 is rotatably connected to the second drive mechanism 102, and the lead screw nut 104 is fixedly connected to the screen assembly 106. The lead screw nut 104 is threadedly connected to the lead screw 108. Thus, when the second drive mechanism 102 is activated, the lead screw 108 rotates accordingly, driving the lead screw nut 104 to move axially along the lead screw 108, thereby causing the screen assembly 106 to move relative to the watch body 107 along the axial direction of the opening. Furthermore, both the lead screw 108 and the lead screw nut 104 can be made of a metal material with relatively good wear resistance to improve the service life and transmission accuracy of the transmission mechanism.

[0041] In the wearable device disclosed in the above embodiments of this application, the threaded screw 108 and the screw nut 104 can always be located inside the watch body 107, and only the screen assembly 106 can extend out of the receiving cavity from the opening. Furthermore, in the process of designing the wearable device, structures such as sealing rings can be used to form a good dynamic sealing state between the screen assembly 106 and the opening, ensuring that the wearable device has reliable airtightness. This can also reduce the failure rate of the transmission mechanism and extend the service life of the transmission mechanism.

[0042] As described above, the first bracket 601 and the second bracket 602 are movably connected so that they can move relative to each other. Optionally, both the first bracket 601 and the second bracket 602 can move relative to the body 107, and the roll-up screen 603 can switch between the retracted state and the unfolded state by manually driving the first bracket 601 and the second bracket 602 to move relative to each other.

[0043] In another embodiment of this application, to reduce the operational difficulty of the rollable screen 603, the first bracket 601 and the watch body 107 can be fixed relative to each other in the circumferential direction of the watch body 107, and the second bracket 602 can move relative to the watch body in the circumferential direction of the watch body 107. In this case, after the screen assembly 106 extends out of the receiving cavity through the opening, the second bracket 602 can be manually driven to move in opposite directions to the first bracket 601, and the rollable screen 603 wound on at least one of them can be gradually unfolded. Correspondingly, by providing magnetic devices or the like on the watch body 107, after the second bracket 602 moves relative to the first bracket 601 to the target position, the second bracket 602 can be kept relatively fixed relative to the first bracket 601, thereby ensuring that the rollable screen 603 remains in the unfolded state. Of course, when it is necessary to switch the rollable screen 603 to the retracted state, the second bracket 602 can also be restored to its ability to move relative to the first bracket 601 by applying external force.

[0044] As described above, in order to reduce the difficulty of relative movement between the first bracket 601 and the second bracket 602, and to improve the reliability of the screen assembly 106, such as Figure 3 As shown, in the circumferential direction of the watch body 107, the first bracket 601 is fixed relative to the watch body 107, and the second bracket 602 is movably engaged with the watch body 107. That is, the second bracket 602 can move relative to the first bracket 601 in the circumferential direction of the watch body 107, thereby driving the roll screen 603 to be unfolded and rolled up.

[0045] Based on the above, the wearable device disclosed in this application may further include a dial 111, which is coaxially arranged with the watch body 107, and the dial 111 and the watch body 107 are rotatably coupled, thereby enabling the dial 111 to rotate relative to the watch body 107 around the center of the watch body 107. Specifically, the dial 111 and the watch body 107 can form a coaxial rotatable coupling relationship through a structure such as a circular slip ring. Of course, the two can also form a rotatable coupling relationship through other devices such as bearings, which is not limited here.

[0046] Simultaneously, by enabling the second bracket 602 to form a relatively fixed relationship with the dial 111 in the circumferential direction of the watch body 107, the dial 111 can drive the second bracket 602 to rotate relative to the first bracket 601. Specifically, magnetic devices can be provided at corresponding positions on the second bracket 602 and the dial 111, so that when the screen assembly 106 switches from the retracted state to the rolled-up state, the second bracket 602 and the dial 111 can be relatively fixed in the circumferential direction of the watch body 107, and the rotation of the dial 111 can drive the second bracket 602 to rotate relative to the first bracket 601, thus unfolding the rollable screen 603. Correspondingly, magnetic devices can also be provided at corresponding positions on the watch body 107, so that after the second bracket 602 rotates relative to the first bracket 601 to the target position, the second bracket 602 can be kept at that target position, and the rollable screen 603 can be kept in the unfolded state.

[0047] More specifically, when the rollable screen 603 switches from the retracted state to the unfolded state, the dial 111 drives the second bracket 602 to rotate relative to the first bracket 601 in a first direction. When the rollable screen switches from the unfolded state to the retracted state, the dial 111 drives the second bracket 602 to rotate relative to the first bracket 601 in a second direction. The first direction and the second direction are respectively clockwise and counterclockwise.

[0048] As described above, magnetic components can be used to provide a limiting effect for the second bracket 602. In another embodiment of this application, a limiting structure can be provided to enable the second bracket 602 and the dial 111 to form a relatively fixed relationship in the circumferential direction of the watch body 107, thereby improving the reliability of the relatively fixed relationship between the two. Specifically, the wearable device disclosed in this application embodiment may also include a limiting member 109, which is disposed on the dial 111 and protrudes relative to the dial 111 so that the limiting member 109 can extend into the second bracket 602 to provide a limiting effect for the second bracket 602. The limiting member 109 can be fixed to the side surface of the dial 111 facing the second bracket 602 by means of adhesive or other methods. The limiting member 109 can be a rod-shaped structure, and the number of limiting members 109 can be one or more, which is not limited herein. It should be noted that the limiting member 109 and the dial 111 need to be relatively fixed in the rotation direction of the second bracket 602. As for the cooperation relationship between the limiting member 109 and the dial 111 in other directions, this article does not limit it.

[0049] Meanwhile, the second bracket 602 has a relief groove 606 and a limiting groove 607 on the side surface facing the limiting member 109, and the relief groove 606 and the limiting groove 607 are interconnected, thereby ensuring that the limiting member 109 can switch between the relief groove 606 and the limiting groove 607. The relief groove 606 extends along the extension and retraction direction of the second bracket 602, and the limiting member 109 and the relief groove 606 move and cooperate in the extension and retraction direction of the second bracket 602. Thus, during the process of the screen assembly 106 switching between the retracted state and the extended state, as the screen assembly 106 moves relative to the dial 111 along the axial direction of the opening, the limiting member 109 can also move within the relief groove 606, ensuring that the presence of the limiting member 109 does not hinder the axial movement of the screen assembly 106 along the opening.

[0050] Furthermore, the limiting groove 607 extends circumferentially along the watch body 107, and since the extension dimension of the limiting groove 607 in the aforementioned circumferential direction is a fixed value greater than zero, for example, it can be one-tenth, one-twentieth, or other values ​​of the circumference of the watch body 107, the limiting member 109 can be restricted by the bottom of the limiting groove 607 during the rotation of the limiting member 109 relative to the watch body 107 by the dial 111, and the limiting member 109 can drive the second bracket 602 to rotate with the dial 111 relative to the watch body 107 during the rotation of the dial 111, so that the display screen 105 gradually unfolds.

[0051] In summary, in the embodiments of this application, the limiting member 109 and the limiting groove 607 are engaged in a limiting cooperation in the direction in which the second bracket 602 rotates relative to the first bracket 601 and switches the screen assembly 106 to the unfolded state. To put it simply, taking the clockwise rotation of the second bracket 602 relative to the first bracket 601 during the process of the screen assembly 106 switching to the unfolded state as an example, the limiting member 109 and the limiting groove 607 also mutually limit each other in the clockwise direction.

[0052] Furthermore, considering that during the operation of the wearable device, especially during the switching between the retracted and rolled-up states, the limiting member 109 frequently moves within the clearance groove 606 and the limiting groove 607, the limiting member 109 can be made of a metal material with relatively strong wear resistance to improve its reliability and service life. Moreover, to further improve the operational stability of the second bracket 602, the limiting member 109 can be designed as a screw-like structure, i.e., it has a cap-like structure. By engaging the cap-like structure of the limiting member 109 with the clearance groove 606 and the limiting groove 607 of the second bracket 602, the dial 111 and the second bracket 602 can also form a limiting engagement relationship along the axial direction of the watch body 107, that is, in the direction perpendicular to the display surface of the rollable screen 603.

[0053] In the above embodiments, the driving force for the relative rotation between the dial 111 and the watch body 107 can be provided manually by the user. In another embodiment of this application, the first driving mechanism further includes a driving member 113, which is installed on the watch body 107. The dial 111 is provided with at least two gear teeth distributed along its own circumference. The driving member 113 meshes with at least two gear teeth through gears to drive the dial 111 to rotate relative to the watch body 107, thereby achieving the purpose of automatic unfolding and automatic rewinding of the roll screen and improving the reliability of the wearable device.

[0054] Specifically, the drive component 113 can be a rotating motor, and a gear can be mounted on its drive shaft. The gear teeth on the dial 111 can be set in the inner ring of the dial 111, so that the drive component 113 and the gear can also be set in the inner ring of the dial 111. On the one hand, this can reduce the size of the wearable device, and on the other hand, it can improve the reliability of the wearable device.

[0055] As described above, during the operation of the wearable device, the screen assembly 106 can switch between a retracted state and a rolled-up state. During the switching process, both the first support 601 and the second support 602 in the screen assembly 106 need to move relative to the body 107 along the axial direction of the opening. In the above embodiment, the first support 601 and the second support 602 are movably connected, and a rollable screen 603 is also provided between them. To ensure the reliability of the second support 602 moving along the axial direction of the opening with the first support 601, and to prevent them from separating during the extension and retraction process, thus affecting the extension and retraction process, optionally, a magnetic device can be provided between them. During the switching process of the screen assembly 106 between the retracted state and the rolled-up state, the magnetic device can be used to keep the first support 601 and the second support 602 in a relatively fixed relationship. This can also prevent the first support 601 and the second support 602 from moving uncontrollably and damaging the rollable screen 603.

[0056] In another embodiment of this application, the wearable device further includes a first limiting structure 605 and a second limiting structure 604. The first limiting structure 605 is disposed on the first support 601, and the second limiting structure 604 is disposed on the second support 602. One of the first limiting structure 605 and the second limiting structure 604 includes a limiting protrusion 6051, and the other includes a limiting groove, ensuring that the first limiting structure 605 and the second limiting structure 604 can form a limiting engagement relationship. Accordingly, the size and shape of the limiting protrusion 6051 and the limiting groove are correspondingly set to provide a reliable limiting effect when they form an engagement relationship. More specifically, both the first limiting structure 605 and the second limiting structure 604 can be fixed to the first support 601 and the second support 602 respectively by means of adhesive bonding or other methods.

[0057] Based on this, when the screen assembly 106 is in the retracted state, the first limiting structure 605 and the second limiting structure 604 are engaged in a limiting cooperation, that is, the first bracket 601 and the second bracket 602 can be limited in the axial direction of the opening. Thus, during the process of the screen assembly 106 switching between the retracted state and the retracted state and the extended state, it is ensured that the first bracket 601 can reliably drive the second bracket 602 to move relative to the body 107 along the axial direction of the opening.

[0058] Furthermore, taking the first limiting structure 605 including a limiting protrusion 6051 and the second limiting structure 604 including a limiting groove as an example, optionally, the first limiting structure 605 may also include a connecting rod 6052, which connects the limiting protrusion 6051 and the first bracket 601. Correspondingly, in addition to the limiting groove, the second limiting structure 604 may also have a through hole, through which the limiting groove communicates with the outside of the second bracket 602. Moreover, the limiting protrusion 6051 and the limiting groove cooperate correspondingly, and the connecting rod 6052 and the through hole cooperate correspondingly. When the limiting protrusion 6051 cooperates with the limiting groove, the limiting protrusion 6051 also engages with the second bracket 602 in a circumferential direction perpendicular to the watch body 107, thereby further preventing relative movement between the first bracket 601 and the second bracket 602 during the switching between the retracted state and the rolled-up state.

[0059] Of course, in order to ensure that the first bracket 601 and the second bracket 602 still have the ability to move normally, so that the screen assembly 106 can switch to the unfolded state after extending out of the receiving cavity, when the screen assembly 106 is in the extended state, the first limiting structure 605 and the second limiting structure 604 move and cooperate in the direction of movement of the first bracket 601 and the second bracket 602.

[0060] As described above, a rollable screen 603 is connected between the first support 601 and the second support 602 of the first drive mechanism, and the first support 601 and the second support 602 can cause the rollable screen 603 to be unfolded or rolled up through relative movement. To further improve the overall performance of the wearable device, optionally, in the wearable device disclosed in this application embodiment, the screen assembly 106 further includes a solar panel, and the solar panel is fixed to the side of the rollable screen 603 opposite to its display surface. That is, a solar panel is provided on the back of the display surface of the rollable screen 603. In this case, by exposing the solar panel to sunlight, the solar panel can generate electricity, and by connecting the solar panel to the battery of the wearable device, it can also be ensured that the solar panel can charge the battery of the wearable device, improving the usability of the wearable device.

[0061] Furthermore, by designing the structure of the first bracket 601 and the second bracket 602 so that they can move relative to each other in two opposite directions, compared to the unfolding process of the rollable screen 603, by making the first bracket 601 and the second bracket 602 move in opposite directions, the solar panel can be exposed on the side where the display surface of the display screen 105 in the wearable device is located. Thus, when it is necessary to use the solar panel to generate electricity, there is no need to set the back of the wearable device to face upwards, further improving the ease of use of the wearable device.

[0062] Correspondingly, when the screen assembly 106 is equipped with a drive unit 113, the drive unit 113 can also have the ability to drive in both forward and reverse directions. Thus, under different needs, the driving direction of the drive unit 113 can be controlled accordingly to achieve the purpose of unfolding the rollable screen 603 or unfolding the solar panel.

[0063] Optionally, the wearable device disclosed in this application embodiment further includes functional components disposed on the screen assembly 106. These functional components include at least one of a camera and a speaker, which can further expand the functional range of the wearable device and improve its overall functionality. More specifically, when the first driving mechanism includes a first bracket 601 and a second bracket 602, at least one functional component can be disposed on at least one of the first bracket 601 and the second bracket 602.

[0064] As described above, the rollable screen 603 is connected between the first bracket 601 and the second bracket 602 of the first driving mechanism, and the rollable screen 603 can be a fan-shaped structure to improve the overall integrity of the display surface on the wearable device. In a specific embodiment of this application, when the screen assembly 106 is in the unfolded state, the rollable screen 603 is symmetrically arranged relative to the watch strap 101, which makes the direction of the content displayed on the rollable screen 603 nearly parallel to the user's line of sight when viewing the wearable device, thereby improving the display effectiveness of the rollable screen 603. More specifically, when the rollable screen 603 is a fan-shaped structure, if the watch strap 101 is regarded as a line segment, the angle bisector of the rollable screen 603 can be located in the plane where the watch strap 101 is located.
