[0061] In today's digital age, wearable devices such as smartwatches and smart bracelets are gradually becoming powerful assistants in people's lives and work due to their convenient functions and real-time information interaction. Whether it's activity monitoring, health data tracking, receiving message reminders, or making payments, they have brought great convenience to people's lives.

[0062] The inventors discovered that, for ease of viewing, the display screen of current wearable devices is typically oriented towards the inside of the wearer's wrist. However, when the wearer needs to show the device to someone else, the other person must move around to face the user, or the user must adjust their wrist so that the other person can see the display screen at eye level, resulting in inconvenience when displaying the device to others.

[0063] The host body, smart host, and wearable device provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0064] Please see Figure 1 This application discloses a host body for use in wearable devices, such as smart bracelets and smartwatches. The host body includes a mid-frame 100 and a display screen 200. The display screen 200 is rotatably disposed on the mid-frame 100, and the rotation axis of the display screen 200 is parallel to the thickness direction of the host body.

[0065] In this application, the display screen 200 is rotatably mounted on the middle frame 100, and the rotation axis of the display screen 200 is parallel to the thickness direction of the main body. Controlling the rotation of the display screen 200 can change the orientation of the display screen 200. Thus, when the wearer needs to show the display screen 200 to others, they only need to rotate the display screen 200 to match the orientation of the display screen 200 with the orientation of the other person, so that the other person can look at the display screen 200 at eye level. In this way, the wearer does not need to adjust the direction of their wrist, nor does the other person need to walk around to the front of the wearer, thereby reducing the difficulty of making the other person look at the display screen 200 at eye level.

[0066] Please see Figure 1 In one alternative embodiment, the display screen 200 is strip-shaped.

[0067] In this embodiment, the display screen 200 is strip-shaped, meaning it has a large aspect ratio. This allows the user to use the ends of the display screen 200 along its length as marker points. The user can observe the relative position between these marker points and the middle frame 100, enabling the display screen 200 to be rotated to the desired position, thus improving the accuracy of the display screen 200's positioning. Of course, the cross-section of the display screen 200 can also be circular, square, etc., and this application does not impose any limitations on this.

[0068] Please see Figures 2 to 5 In an optional embodiment, the middle frame 100 has a first mating portion 110 and a second mating portion 120 for connection with the connecting strap 600 of a wearable device, the first mating portion 110 and the second mating portion 120 being along a first direction ( Figure 2 and Figure 3 (The direction indicated by the X-arrow line) is relative to the setting. Specifically, the user can wear the main unit on their wrist via the connection strap 600.

[0069] The display screen 200 is rotatable between a first position and a second position, wherein the display screen 200 is in the first position ( Figure 2 When the position shown is such that the first end of the display screen 200 is located on the first side of the straight line in the first direction, and the first end of the display screen 200 is closer to the first mating portion 110 than the second end, the length direction of the display screen 200 (as shown) Figure 2 and Figure 3 The direction indicated by the arrow in the middle is tilted relative to the first direction.

[0070] When the display screen 200 is in the second position ( Figure 3 When the position shown is such that the first end of the display screen 200 is located on the first side of the straight line in the first direction, and the first end of the display screen 200 is closer to the second docking portion 120 than the second end.

[0071] In this embodiment, when the display screen 200 is in the first position, the length direction of the display screen 200 is tilted relative to the first direction. When the display screen 200 is in the second position, the length direction of the display screen 200 is also tilted relative to the first direction. Moreover, when the display screen 200 is in the first position and the second position respectively, the tilt direction of the length direction of the display screen 200 relative to the first direction is opposite. Therefore, when the display screen 200 is in the first position, it is suitable for one of the two wearing methods: left-hand wearing and right-hand wearing. When the display screen 200 is in the second position, it is suitable for the other of the two wearing methods.

[0072] Furthermore, regardless of whether the main unit is worn on the user's wrist in the left or right hand, the display screen 200 will be tilted relative to the user's arm in both length and width. Therefore, the user only needs to rotate their arm or head slightly to align the length or width of the display screen 200 roughly with their line of sight, conforming to their viewing habits and improving the user experience. Additionally, in some usage scenarios, such as cycling, exercising, or typing at work, the user's arm is naturally tilted relative to their body. In these situations, the user does not need to tilt their arm horizontally to view the display screen 200 naturally, further enhancing the user experience.

[0073] In some other embodiments, the display screen 200 can also be rotated to a position where its length direction is perpendicular to the first direction, or it can also be rotated to a position where its length direction is collinear with the first direction. This application does not limit this.

[0074] Please see Figure 2 In one optional embodiment, when the display screen 200 is in the first position, the minimum angle between the straight line containing the length direction of the display screen 200 and the straight line containing the first direction is 30° to 60°. For example, the aforementioned minimum angle can be 32°, 35°, 38°, 42°, 43°, 45°, 50°, 53°, 55°, 58°, etc., and this application does not limit it to these values.

[0075] If the minimum included angle mentioned above is less than 30°, then when using Figure 2 In the illustrated scheme, the user can view the display screen 200 directly and naturally with only a small angle of arm rotation. However, this distance between the wrist and the display screen 200 and the user's eyes makes it difficult for the user, especially those with poor eyesight, to observe small text or icons on the screen. If the minimum angle mentioned above is greater than 60°, when using… Figure 2 The proposed solution reduces the degree of reduction in the user's arm rotation angle.

[0076] Therefore, in this embodiment, the minimum included angle is controlled within 30° to 60°, ensuring that the size of this minimum included angle is within a suitable range. This allows for the application of… Figure 2 The solutions shown can both increase or decrease the angle of the user's arm rotation, and ensure that when the user looks directly and naturally at the display screen, the distance between the user's eyes and the display screen 200 is within a suitable range, making it easier for the user to observe smaller text or icons on the display screen.

[0077] Please see Figure 3 In one optional embodiment, when the display screen 200 is in the second position, the minimum angle between the straight line containing the length direction of the display screen 200 and the straight line containing the first direction is 30° to 60°. For example, the aforementioned minimum angle can be 32°, 35°, 38°, 42°, 43°, 45°, 50°, 53°, 55°, 58°, etc., and this application does not limit it to these values.

[0078] Similar to the analysis of the previous embodiment, this embodiment controls the minimum included angle to be between 30° and 60°, which ensures that the size of the minimum included angle is within a suitable range, thus enabling the application of... Figure 3 The solutions shown can both increase or decrease the angle of the user's arm rotation, and ensure that when the user looks directly and naturally at the display screen, the distance between the user's eyes and the display screen 200 is within a suitable range, making it easier for the user to observe smaller text or icons on the display screen.

[0079] Please see Figure 1 and Figure 6 In one optional embodiment, the main body further includes a rotating shell 300, which is rotatably connected within the middle frame 100. The display screen 200 is disposed on the rotating shell 300 and is rotatably connected to the middle frame 100 via the rotating shell 300. It should be noted that a damping structure can be provided between the rotating shell 300 and the middle frame 100 to allow the rotating shell 300 to remain in the desired position.

[0080] In this embodiment, the display screen 200 is disposed on the rotating shell 300. The position between the display screen 200 and the rotating shell 300 is relatively fixed. The rotating shell 300 can rotate relative to the middle frame 100. During the rotation of the rotating shell 300 relative to the middle frame 100, it will drive the display screen 200 to rotate relative to the middle frame 100, so as to change the orientation of the display screen 200.

[0081] Since the position between the display screen 200 and the rotating housing 300 does not change during the rotation of the display screen 200 relative to the middle frame 100, when a component (such as a circuit board) that needs to be electrically connected to the display screen 200 is installed inside the rotating housing 300, the component can be directly connected to the display screen 200 using a cable, without the need for a movable electrical contact structure, thus simplifying the electrical connection structure between the display screen 200 and the component. Furthermore, since the position between the display screen 200 and the rotating housing 300 does not change, the display screen 200 will not be subject to sliding friction, thereby preventing damage to the display screen 200 under the action of sliding friction. Of course, the main unit may not include the rotating housing 300. In this case, the display screen 200 can be located on the middle frame 100 and can rotate relative to the middle frame 100, and the display screen 200 and the circuit board of the main unit can be electrically connected using a movable electrical contact.

[0082] Please see Figure 7 In one optional embodiment, a limiting structure is provided between the rotating shell 300 and the middle frame 100 to prevent the rotating shell 300 and the middle frame 100 from separating along the thickness direction of the main body. It should be noted that when this embodiment is combined with the embodiment described below where the annular guide portion 310 is an annular groove and the mating portion 130 is a protrusion, the limiting structure may include the annular guide portion 310 and the mating portion 130.

[0083] In this embodiment, the limiting structure between the rotating shell 300 and the middle frame 100 can prevent the rotating shell 300 from detaching from the middle frame 100 along the thickness direction of the main body, thus ensuring the stability of the fit between the rotating shell 300 and the middle frame 100.

[0084] Please see Figures 6 to 9 In one optional embodiment, one of the inner peripheral wall of the middle frame 100 and the outer peripheral wall of the rotating shell 300 is provided with an annular guide portion 310, and the other is provided with a mating portion 130. The annular guide portion 310 is arranged around the rotation axis, and the mating portion 130 slides with the annular guide portion 310 to allow the rotating shell 300 to rotate around the rotation axis.

[0085] In this embodiment, the rotating shell 300 can rotate relative to the middle frame 100 through the engagement between the mating part 130 and the annular guide part 310. Since the annular guide part 310 is arranged around the rotation axis and extends around the circumference of the middle frame 100, the mating part 130 rotates 360 degrees around the rotation axis when it slides around the annular guide part 310. In other words, with the structure of this embodiment, the rotating shell 300 can rotate 360 ​​degrees relative to the middle frame 100, so that the display screen 200 can face any direction, making it easier for others to view the display screen 200.

[0086] Of course, in other embodiments, one of the inner peripheral wall of the middle frame 100 and the outer peripheral wall of the rotating shell 300 may be provided with an arc-shaped guide portion, and the other is provided with a mating portion 130. The arc-shaped guide portion is arranged around the rotation axis, and the mating portion 130 slides with the arc-shaped guide portion to allow the rotating shell 300 to rotate around the rotation axis.

[0087] Please see Figures 7 to 9 In one optional embodiment, the outer peripheral wall of the middle frame 100 is provided with a first receiving groove 101 for accommodating the accessory 500, the outer peripheral wall of the rotating shell 300 is provided with an annular guide portion 310, the annular guide portion 310 is an annular groove, and the inner peripheral wall of the middle frame 100 is provided with a mating portion 130 corresponding to the portion of the first receiving groove 101, the mating portion 130 is a protrusion, and the first receiving groove 101 extends inward into the mating portion 130.

[0088] In this embodiment, the outer peripheral wall of the rotating shell 300 is provided with an annular guide portion 310, and the inner peripheral wall of the middle frame 100 is provided with a mating portion 130. The annular guide portion 310 is an annular groove, and the mating portion 130 is a protrusion. At least a portion of the protrusion is slidably connected within the annular groove. During the sliding process of the protrusion relative to the annular groove, the protrusion rotates around the aforementioned rotation axis to achieve the purpose of rotating the rotating shell 300 relative to the middle frame 100. In addition, the outer peripheral wall of the middle frame 100 in this embodiment is provided with a first receiving groove 101 for accommodating the accessory 500. The first receiving groove 101 extends into the protrusion, which allows the first receiving groove 101 to have a deeper dimension, so that the first receiving groove 101 can accommodate a larger accessory 500.

[0089] It should be noted that the rotating shell 300 may include two sub-shells distributed along the thickness direction of the main body. The two sub-shells cooperate to form an annular groove, which facilitates the assembly of the protrusion into the annular groove.

[0090] Please see Figure 1 and Figure 6 In one optional embodiment, the rotating shell 300 is provided with a mounting cavity 301, the mounting cavity 301 has a mounting opening, the display screen 200 covers the mounting opening, the rotating shell 300 is provided with a recess 302 located on one side of the mounting cavity 301, the recess 302 penetrates the surface of the rotating shell 300 where the mounting opening is provided, and the recess 302 is exposed to the display screen 200, that is, the display screen 200 does not cover the recess 302.

[0091] In this embodiment, the rotating shell 300 is provided with a cavity 302, which penetrates the surface of the rotating shell 300 where the mounting opening is located. The display screen 200 does not cover the cavity 302. The cavity 302 provides a point of application for the user's fingers or tools. The user can rotate the rotating shell 300 relative to the middle frame 100 by using their fingers or tools to move the inner wall of the cavity 302. Furthermore, the inner wall of the cavity 302 can prevent the user's fingers or tools from slipping, ensuring that the user can stably drive the rotating shell 300 to rotate, thereby driving the display screen 200 to rotate. Of course, the rotating shell 300 may not have a cavity 302, and this application does not limit this.

[0092] Please see Figure 1 In one optional embodiment, the mounting cavity 301, the mounting opening, and the display screen 200 are all strip-shaped, and the number of recesses 302 includes two, with the two recesses 302 located on both sides of the mounting cavity 301 along its own width direction.

[0093] In this embodiment, there are two recesses 302. These two recesses 302 provide the user with more leverage points, making it easier to drive the rotating shell 300 to rotate. Furthermore, the two recesses 302 are located on opposite sides of the mounting cavity 301 along its width. Since the mounting cavity 301 is strip-shaped, its width is smaller than its length. Therefore, placing the two recesses 302 on opposite sides of the mounting cavity 301 along its width results in a smaller distance between them. This better accommodates the distance between the thumb and forefinger when the user naturally opens their hand, making the posture of the user's thumb and forefinger when inserting into the two recesses 302 more natural. Of course, there can also be only one recess 302; this application does not limit this.

[0094] Please see Figure 1 In one alternative embodiment, the recess 302 penetrates the surface of the rotating shell 300 away from the mounting opening, and the recess 302 and the mounting cavity 301 are isolated from each other by the solid portion of the rotating shell 300.

[0095] In this embodiment, the cavity 302 penetrates the surface of the rotating shell 300 where the mounting opening is provided, and also penetrates the surface of the rotating shell 300 away from the mounting opening. That is, the cavity 302 penetrates the rotating shell 300 along the thickness direction of the main body. This allows the cavity 302 to be connected to the external environment, and the relatively cool air in the external environment can be replenished into the cavity 302 in a timely manner, thereby accelerating the heat dissipation inside the rotating shell 300 and extending the service life of the components inside the rotating shell 300.

[0096] Furthermore, providing a through-hole cavity 302 in the rotating shell 300 can reduce the solid material of the rotating shell 300, thereby reducing its weight and improving the user's wearing experience. The cavity 302 also allows for air exchange between the user's skin and the outside air, preventing the skin from being in an unbreathable environment for extended periods, reducing stuffiness, and further enhancing the user's wearing experience. Of course, the cavity 302 may not penetrate the surface of the rotating shell 300 away from the mounting opening; this application does not impose any limitation on this.

[0097] Please see Figure 6 , Figures 8 to 10 In one optional embodiment, the outer peripheral wall of the middle frame 100 is provided with a first receiving groove 101 for accommodating the accessory 500. The main body includes a circuit board and a first contact 400 that are electrically connected to each other. The circuit board is disposed inside the rotating shell 300, and the first contact 400 is disposed in the rotating shell 300 and exposed on the outer peripheral wall of the rotating shell 300. The first contact 400 extends circumferentially along the middle frame 100 so that the first contact 400 and the second contact 510 of the accessory 500 are kept in electrical contact when the rotating shell 300 rotates relative to the middle frame 100.

[0098] In this embodiment, the first contact 400 of the main body is exposed on the outer peripheral wall of the rotating shell 300. When the accessory 500 is disposed in the first receiving groove 101, the second contact 510 of the accessory 500 is in electrical contact with the first contact 400, thereby realizing the interaction between the accessory 500 and the main body. For example, the main body can be used to charge the accessory 500. Furthermore, in this embodiment, the first contact 400 extends circumferentially along the middle frame 100. Thus, even if the rotating shell 300 rotates relative to the middle frame 100, the second contact 510 of the accessory 500 can remain in contact with the first contact 400 of the main body, preventing the second contact 510 from disengaging from the first contact 400 and causing the main body to be unable to charge the accessory 500.

[0099] Please see Figure 2 and Figure 3 In one optional embodiment, the rotation axis passes through the display surface of the display screen 200. It should be noted that the display surface is the surface of the display screen 200 that is viewed by the user.

[0100] Compared to embodiments where the rotation axis is located outside the display surface, this embodiment makes the rotation axis pass through the display surface of the display screen 200. In this way, during the rotation of the display screen 200 relative to the middle frame 100, the amplitude of the eccentric sway of the display screen 200 can be reduced, or even the eccentric sway of the display screen 200 can be avoided, thereby reducing the space occupied by the display screen 200 within the middle frame 100 during the rotation.

[0101] Please see Figure 2 and Figure 3In one optional embodiment, the rotation axis passes through the geometric center of the display surface of the display screen 200. For example, when the display surface is circular, the geometric center of the display surface is circular; when the display surface is rectangular, the geometric center of the display surface is the intersection of the diagonals of the rectangle; when the display screen 200 is racetrack-shaped, the racetrack shape includes a rectangular area and semicircular areas located on both sides of the rectangular area, and the geometric center of the display surface is the intersection of the diagonals of the rectangular area.

[0102] In this embodiment, the rotation axis passes through the geometric center of the display surface of the display screen 200. In this way, during the rotation of the display screen 200 relative to the middle frame 100, the eccentric sway of the display screen 200 can be avoided, thereby further reducing the space occupied by the display screen 200 within the middle frame 100 during the rotation.

[0103] Please see Figure 2 and Figure 3 In one optional embodiment, the middle frame 100 is annular, and the axis of rotation is the central axis of the middle frame 100.

[0104] In this embodiment, the axis of rotation is the central axis of the middle frame 100, which prevents the display screen 200 from extending beyond the outer edge of the middle frame 100 during rotation. Furthermore, when this embodiment is combined with an embodiment where the axis of rotation passes through the geometric center of the display surface of the display screen 200, the minimum distance between the outer edge of the middle frame 100 and the outer edge of the display screen 200 remains unchanged during rotation. Of course, the axis of rotation can also be separated from the central axis of the middle frame 100; this application does not impose any limitation on this.

[0105] Please see Figure 1 This application also discloses a smart host, comprising:

[0106] As in any of the above embodiments, the host body thus enables the intelligent host to possess the beneficial effects of the aforementioned host body, which will not be repeated here.

[0107] Accessory 500 is detachably disposed on the periphery of the middle frame 100. For example, accessory 500 may include at least one of headphones, power bank, speaker, camera module or blood pressure measuring pump module.

[0108] Please see Figure 8 , Figure 9 and Figure 11 In one optional embodiment, the main body of the host also includes a rotating shell 300, which is disposed within the middle frame 100, and the display screen 200 is disposed in the rotating shell 300. The rotating shell 300 is capable of rotating relative to the middle frame 100 about a rotation axis.

[0109] Accessory 500 is an earphone. The outer peripheral wall of the middle frame 100 is provided with a first groove 1011, which penetrates the inner peripheral wall of the middle frame 100. The outer peripheral wall of the rotating shell 300 is provided with a second receiving groove 303 extending in a ring shape along its own circumference. The first groove 1011 is provided corresponding to the second receiving groove 303. For example, the outer peripheral wall of the middle frame 100 is also provided with a second groove 1012. The first groove 1011 and the second groove 1012 are connected in the circumference of the middle frame 100. The second groove 1012 is used to receive the earphone's handle portion 530.

[0110] The earphone includes a receiver 520, one end of which can pass through the first groove 1011 and be received in the second receiving groove 303.

[0111] In this embodiment, when the earphone is located on the periphery of the middle frame 100, the earpiece 520 of the earphone extends into the second receiving groove 303 through the first groove 1011. The second receiving groove 303, located on the outer peripheral wall of the rotating shell 300, extends around the circumference of the rotating shell 300. Therefore, when the rotating shell 300 is rotated to any angle relative to the middle frame 100, the earpiece 520 can extend into the second receiving groove 303 after passing through the first groove 1011. Thus, the earpiece 520 can be installed into the second receiving groove 303 without deliberately aligning the positions of the first groove 1011 and the second groove 1012.

[0112] Please see Figure 10 and Figure 11 In one optional embodiment, the main body includes a first annular contact 400, which is disposed on the bottom wall of the second receiving groove 303 and extends circumferentially along the rotating shell 300. The earphone includes a second contact 510, which is disposed on the earpiece portion 520 and exposed on the surface of the earpiece portion 520 opposite to the bottom wall of the second receiving groove 303. When the earphone is disposed on the periphery of the middle frame 100, the second contact 510 and the first contact 400 make electrical contact to realize the interaction between the main body and the earphone.

[0113] The first contact 400 is located on the bottom wall of the second receiving groove 303. Therefore, the first contact 400 is far from the outer peripheral wall of the middle frame 100 and the bottom wall of the first receiving groove 101. If the second contact 510 is also located on the earpiece portion 520, a boss needs to be provided on the earpiece portion 520 to make the second contact 510 electrically contact the first contact 400, which would make the headphone structure more complex. However, the earpiece portion 520 of the headphone has a large protrusion height and is located in the second receiving groove 303. Therefore, in this embodiment, the second contact 510 is directly connected to the first contact 400 by utilizing the protrusion height of the earpiece portion 520. This eliminates the need to provide an additional boss on the headphone, thereby simplifying the headphone structure.

[0114] This application also discloses a wearable device, including a smart host as described in any of the above embodiments. For example, the wearable device may further include a connecting strap 600, which is connected to the mid-frame 100, so that the user can wear the host body on their wrist.

As long as the different optimization features between embodiments are not contradictory, they can be combined to form better embodiments. For the sake of brevity, these differences will not be elaborated upon here. The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
