[0004] This application discloses a host body, accessories, and a smart host, which can reduce the risk of damage to accessories installed on the outside of the host body when subjected to external forces.

[0005] To achieve the above objectives, in a first aspect, embodiments of this application disclose a host body applied to a wearable device. The host body has a receiving groove extending circumferentially on its outer peripheral wall. The receiving groove is used to receive accessories of the wearable device and is arc-shaped.

[0013] In one optional embodiment, the main body has a shielding portion formed on the portion corresponding to the second end of the receiving groove. The shielding portion covers the opening of the second end of the receiving groove. The shielding portion cooperates with the receiving groove to form a second groove. The depth direction of the second groove is parallel to the depth direction of the first groove.

[0014] In one optional embodiment, the main body is provided with a first docking portion and a second docking portion for connecting with the connecting strap of a wearable device, the first docking portion and the second docking portion being located on opposite sides of the main body;

[0015] The number of receiving slots includes two, and the bottom wall of the first end of each receiving slot is provided with the first groove. The two receiving slots are respectively located on both sides of the first straight line in the arrangement direction of the first docking part and the second docking part, and the first straight line passes through the center of the main body.

[0016] In one alternative embodiment, the two receiving slots are arranged symmetrically about the axis of the host body.

[0017] In one optional embodiment, the main body includes a mid-frame, the mid-frame being annular, and the receiving groove being disposed on the outer peripheral wall of the mid-frame, the mid-frame and the receiving groove being concentrically arranged; and / or,

[0018] The main body includes a display screen, a mid-frame, and a shell body. The shell body is formed within the mid-frame along its circumference. The display screen is disposed within the shell body. The first groove is disposed within the shell body; and / or,

[0019] The outer peripheral wall of the main body has a guide surface, which is in contact with the inner wall of the first groove. The guide surface is used to guide the earphone into the receiving groove.

[0020] In one optional embodiment, the main body includes a middle frame, the middle frame being annular, and the receiving groove being disposed on the outer peripheral wall of the middle frame;

[0021] The curvature of the receiving groove is a perfect circle; and / or, the circumferential extension length of the receiving groove is one-quarter to one-half of the circumference of the outer edge of the middle frame; and / or, the diameter of the outer edge of the middle frame is 40mm to 55mm, and the circumferential extension length of the receiving groove is 45mm to 61mm.

[0022] In one optional embodiment, the main body is provided with a first docking portion and a second docking portion for connecting with the connecting strap of a wearable device, the first docking portion and the second docking portion being located on opposite sides of the main body;

[0023] The host body includes a display screen, which is strip-shaped. The length direction of the display screen is at a preset angle to the arrangement direction of the first docking part and the second docking part. The preset angle is greater than 0° and less than or equal to 90°.

[0024] In one optional embodiment, the preset angle is 30° to 60°.

[0025] In one optional embodiment, the preset angle is 90°.

[0026] Secondly, this application discloses an accessory for use in a wearable device. The wearable device includes a main body, and the accessory is arc-shaped and can be detachably disposed in an arc-shaped receiving groove on the outer peripheral wall of the main body. The accessory can be engaged with the main body in the circumferential direction of the main body.

[0027] In one alternative embodiment, the accessory is an earphone, which includes a connected earpiece and a handle, the handle being arc-shaped.

[0028] Thirdly, embodiments of this application disclose a smart host, including:

[0029] The host body described in any of the above embodiments;

[0030] The accessory described in any of the above embodiments is detachably installed in the receiving groove;

[0031] The shape of the receiving groove is adapted to the shape of the part of the accessory located in the receiving groove, and the end of the accessory is positioned and engaged with the main body along the circumference of the main body.

[0032] In one alternative embodiment, a portion of the fitting is exposed outside the receiving groove along its depth direction;

[0033] The accessory includes a first housing and a second housing distributed along the depth direction of the receiving groove, the first housing and the second housing being connected, and the fitting gap between the first housing and the second housing being located within the receiving groove.

[0034] Compared with related technologies, the beneficial effects of this application are:

[0035] In this application, the outer peripheral wall of the main body is provided with a receiving groove for accommodating accessories. After the accessories are accommodated in the receiving groove, the main body can stop and limit the accessories along the circumferential direction of the main body. Therefore, when the accessories are subjected to external force, the main body can stop and limit the accessories. Since the receiving groove is arc-shaped, the shape of the receiving groove is adapted to the shape of the part of the accessories located in the receiving groove. Therefore, the contact surface between the accessories and the receiving groove is a conformal curved surface with matching curvature. When the accessories are subjected to force, the force will cause the accessories to tend to move along the chord direction of the receiving groove. Since the accessories are in contact with the inner wall of the receiving groove, the above-mentioned chord direction movement tendency will force the accessories to squeeze the inner wall of the receiving groove. The inner wall of the receiving groove can generate a chord direction support force on the accessories through the contact point, preventing the accessories from displacing.

[0036] As can be seen, this application can not only limit the position of the accessory by cooperating with the main body, but also limit the position of the accessory by cooperating with the shape of the receiving groove. This can disperse the stress on the accessory, prevent stress concentration, and reduce the risk of damage to the accessory.

[0037] Furthermore, when the positions of the two ends of the receiving groove are determined, the arc-shaped receiving groove of this application has a longer extension length compared to the zigzag receiving groove. This allows the fitting to have a greater extension length, so that the key components inside the fitting can have larger dimensions, thereby improving the performance of the fitting.

[0054] 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 embodiments of this application, and not all embodiments. 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.

[0055] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0059] Wearable devices that combine a watch and headphones represent a fusion of technology and fashion. These devices integrate the stylish appearance of a watch with the portability of headphones, offering not only standard functions such as time display but also the convenience of enjoying music or making calls anytime.

[0060] In related technologies, the earphones are detachably mounted on the outside of the watch, and there is a possibility that the earphones may be damaged when subjected to external force.

[0061] The inventors discovered that, in order to install headphones, the relevant technology sets a receiving groove on the outer periphery of the watch, and the headphones are matched with the watch along the circumference of the watch to ensure the stability of the headphones in the receiving groove and prevent the headphones from falling off the watch when subjected to external force.

[0062] The inventors further discovered that in the related technology, both the receiving slot and the earphone extend in a straight line. When the earphone is subjected to external force, only the end of the earphone is in contact with the watch limiter. Therefore, stress concentration is likely to occur at the end of the earphone, resulting in excessive local stress on the end of the earphone. When the local stress exceeds the load-bearing capacity of the earphone, it may cause damage to the earphone, such as cracking of the earphone shell or loosening of internal components.

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

[0064] like Figures 1 to 8As shown in the figure, this application embodiment discloses a host body for use in wearable devices, such as smartwatches, smart bracelets, smart belts, etc. The host body 100 has a receiving groove 101 extending along its circumference on its outer peripheral wall. The receiving groove 101 is used to receive accessories 200 of the wearable device and is arc-shaped.

[0065] Along the circumference of the main body 100, the main body 100 can stop and limit the accessory 200 accommodated in the receiving groove 101. That is, after the accessory 200 is accommodated in the receiving groove 101, the first end of the accessory 200 along its own circumference ( Figure 2 The end indicated by the arrow in the middle (g) is circumferentially limited and engaged with the main body 100 in a clockwise direction, and the second end of the accessory 200 in its own circumferential direction ( Figure 2 The end indicated by the arrow in the middle (h) is matched with the main body 100 in a counterclockwise circumferential limiting manner.

[0066] For example, the receiving groove 101 has a first end wall 1011 and a second end wall 1012 distributed circumferentially along the main body 100. The first end of the accessory 200 contacts the first end wall 1011, and the second end of the accessory 200 contacts the second end wall 1012, so as to achieve the purpose of the main body 100 stopping and limiting the accessory 200.

[0067] In this application, the outer peripheral wall of the main body 100 is provided with a receiving groove 101 for accommodating the accessory 200. After the accessory 200 is accommodated in the receiving groove 101, the main body 100 can stop and limit the accessory 200 along the circumferential direction of the main body 100. Therefore, when the accessory 200 is subjected to external force, the main body 100 can stop and limit the accessory 200. Furthermore, since the receiving groove 101 is arc-shaped, the shape of the receiving groove 101 is adapted to the shape of the part of the accessory 200 located in the receiving groove 101. Therefore, the contact surface between the accessory 200 and the receiving groove 101 is a conformal surface with matching curvature. When the accessory 200 is subjected to a force, the force will cause the accessory 200 to tend to move along the chord direction of the receiving groove 101. Since the accessory 200 is in contact with the inner wall of the receiving groove 101, the above-mentioned chord direction movement tendency will force the accessory 200 to squeeze the inner wall of the receiving groove 101. The inner wall of the receiving groove 101 can generate a chord direction support force on the accessory 200 through the contact point, preventing the accessory 200 from displacing.

[0068] As can be seen, this application can not only use the cooperation between the accessory 200 and the main body 100 to limit the accessory 200, but also use the shape cooperation between the accessory 200 and the receiving groove 101 to limit the accessory 200. In this way, the stress on the accessory 200 can be dispersed, stress concentration can be prevented, and the risk of damage to the accessory 200 can be reduced.

[0069] Furthermore, when the positions of the two ends of the receiving groove 101 are determined, the arc-shaped receiving groove 101 of this application has a longer extension length than the zigzag receiving groove 101. This allows the accessory 200 to have a larger extension length, so that the key components within the accessory 200 can have larger dimensions, thereby improving the performance of the accessory 200.

[0070] If the extension length of the opening of the receiving groove 101 is less than the extension length of the receiving groove 101, a part of the receiving groove 101 will be covered. When the accessory 200 is inserted into the receiving groove 101, one end of the accessory 200 needs to be inserted into the covered part of the receiving groove 101. The part of the accessory 200 inserted into the receiving groove 101 is defined as the inner insertion part. The longer the length of the receiving groove 101 that is covered, the longer the length of the inner insertion part of the accessory 200, and the more time it takes for the accessory 200 to be inserted into the receiving groove 101.

[0071] Please see Figures 2 to 5 In one optional embodiment, the receiving slot 101 has an opening extending from one end to the other along the circumference of the host body 100, and the extension length of the opening is greater than or equal to four-fifths of the extension length of the receiving slot 101. Exemplarily, the extension length of the opening can be equal to five-sixths, seven-eighths, nine-tenths, etc., of the extension length of the receiving slot 101, and even the extension length of the opening can be equal to the extension length of the receiving slot 101; this application does not limit this. Please refer to... Figure 3 The opening of the receiving groove 101 is formed by the groove edge 1013 of the receiving groove 101, and the opening is set opposite to the bottom wall of the receiving groove 101.

[0072] In this embodiment, along the circumference of the main body 100, the extension length of the slot is greater than or equal to four-fifths of the extension length of the receiving slot 101. That is, the slot has a large extension length, and the portion of the receiving slot 101 that is covered is very small, or even all of the receiving slot 101 is not covered. At this time, the length of the inner insertion part of the accessory 200 is very small, or even there is no inner insertion part. Thus, the time required to insert the accessory 200 into the receiving slot 101 is less, thereby improving the efficiency of loading or unloading the accessory 200 into or out of the receiving slot 101.

[0073] Please see Figure 1 and Figure 5 In one optional embodiment, the main body 100 is provided with a first docking portion 110 and a second docking portion 120 for connecting with the connecting strap 300 of the wearable device. That is, the first end of the connecting strap 300 is connected to the first docking portion 110, and the second end of the connecting strap 300 is connected to the second docking portion 120. The main body 100 can be worn on the user's wrist through the connecting strap 300.

[0074] The first docking portion 110 and the second docking portion 120 are located on opposite sides of the main body 100, and each of the first docking portion 110 and the second docking portion 120 is provided with a receiving cavity 102. For example, the receiving cavity 102 in the first docking portion 110 and the receiving cavity 102 in the second docking portion 120 are both provided with a snap-fit ​​portion, and the first end and the second end of the connecting belt 300 are both provided with snap-fit ​​mating portions, which can snap-fit ​​with the corresponding snap-fit ​​mating portions.

[0075] Along the circumference of the main body 100, the receiving groove 101 is located between the receiving cavity 102 in the first docking part 110 and the receiving cavity 102 in the second docking part 120.

[0076] In this embodiment, along the circumference of the main body 100, the receiving groove 101 is located between the receiving cavity 102 in the first docking portion 110 and the receiving cavity 102 in the second docking portion 120. The receiving groove 101 does not occupy the receiving cavity 102 in the first docking portion 110 and the receiving cavity 102 in the second docking portion 120. After the accessory 200 is inserted into the receiving groove 101, the accessory 200 will not occupy the receiving cavity 102 in the first docking portion 110 and the receiving cavity 102 in the second docking portion 120. That is, the accessory 200 is located outside the receiving cavity 102 in the first docking portion 110 and the receiving cavity 102 in the second docking portion 120. Thus, the receiving cavity 102 in the first docking portion 110 and the receiving cavity 102 in the second docking portion 120 can be used to set other components, such as a snap-fit ​​portion for snapping with the connecting strap 300. Therefore, with the structure of this embodiment, the accessory 200 will not affect the layout of the components in the first docking portion 110 and the second docking portion 120 after being inserted into the receiving groove 101. Of course, after the accessory 200 is inserted into the receiving groove 101, the accessory 200 may also extend into the receiving cavity 102 in the first docking part 110 and / or the second docking part 120, and this application does not limit this.

[0077] Please see Figure 5 In one alternative embodiment, the two ends of the receiving groove 101 extend to the first docking portion 110 and the second docking portion 120, respectively.

[0078] In this embodiment, the receiving groove 101 extends from the main body 100 near the first docking portion 110 to the main body 100 near the second docking portion 120. This allows the receiving groove 101 to have a larger extension length, thereby allowing the accessory 200 to have a larger extension length and allowing the key components within the accessory 200 to have larger dimensions, thereby improving the performance of the accessory 200.

[0079] Please see Figure 5 In one alternative embodiment, one end of the receiving groove 101 extends into the first docking portion 110.

[0080] In this embodiment, one end of the receiving groove 101 extends into the first docking portion 110. That is, the receiving groove 101 extends into the solid structure of the first docking portion 110. In this way, the first docking portion 110 can be used to accommodate the accessory 200, thereby giving the accessory 200 a greater extension length and giving the key components inside the accessory 200 a larger size, so as to further improve the performance of the accessory 200.

[0081] Please see Figure 3 and Figure 5 In one optional embodiment, the accessory 200 is an earphone, and the bottom wall of the first end of the receiving groove 101 is provided with a first groove 103 for accommodating the earpiece portion 230 of the earphone. It should be noted that the bottom wall of the receiving groove 101 refers to the inner wall of the receiving groove 101 opposite to its own opening. This embodiment can prevent the earphone from being damaged when subjected to external force.

[0082] For example, the first groove 103 here has a third end wall 1031 distributed circumferentially along the main body 100. The side of the earpiece portion 230 away from the handle portion 240 can contact the third end wall 1031. In this case, the earpiece portion 230 may not contact the first end wall 1011.

[0083] Of course, in addition to headphones, accessory 200 can also be at least one of power bank, speaker, camera module or blood pressure measuring pump module. The receiving slot 101 is used to accommodate accessories 200 with different functions according to different needs.

[0084] Please see Figure 5 In one optional embodiment, the main body 100 has a blocking portion 130 formed at the second end of the receiving groove 101. The blocking portion 130 covers the opening of the second end of the receiving groove 101, and the blocking portion 130 cooperates with the receiving groove 101 to form a second groove 104. The depth direction of the second groove 104 is parallel to the depth direction of the first groove 103, that is, the opening of the second groove 104 faces the same direction as the opening of the first groove 103. It should be noted that when the earphone is received in the receiving groove 101, the end of the handle portion 240 away from the earpiece portion 230 is located in the second groove 104.

[0085] In this embodiment, the blocking part 130 of the main body 100 covers the slot at the second end of the receiving groove 101. The blocking part 130 and the receiving groove 101 cooperate to form a second groove 104. The depth direction of the second groove 104 is parallel to the depth direction of the first groove 103. Therefore, the headphones can only be inserted into or removed from the receiving groove 101 along the depth direction of the first groove 103. This can prevent the user from accidentally removing the headphones from the receiving groove 101 when it is not necessary to remove the headphones.

[0086] Please see Figure 2 and Figure 7 In one optional embodiment, the main body 100 is provided with a first docking portion 110 and a second docking portion 120 for connecting with the connecting strap 300 of the wearable device, and the first docking portion 110 and the second docking portion 120 are respectively located on opposite sides of the main body 100.

[0087] The number of receiving slots 101 includes two, and the bottom wall of the first end of each receiving slot 101 is provided with a first groove 103. The two receiving slots 101 are respectively located on the first straight line in the arrangement direction of the first docking portion 110 and the second docking portion 120. Figure 7 On both sides of the straight line (shown by the dashed line in the diagram), the first straight line passes through the center of the main unit 100, where the center of the main unit 100 refers to its geometric center. One receiving slot 101 is located on one side of the first straight line, and the other receiving slot 101 is located on the other side of the first straight line. Specifically, with Figure 7 Taking the view shown as an example, the two receiving slots 101 are located on the left and right sides of the first straight line, respectively.

[0088] In this embodiment, there are two receiving slots 101, located on opposite sides of the first straight line. This design ensures that when both slots 101 contain earphones, the weight of the smart host is approximately equal on both sides of the first straight line, allowing the wearable device to be more stably distributed on the wrist. If one side is heavier than the other, the wearable device is prone to tilting to one side, resulting in uneven force on the contact area between the wearable device and the wrist. This can cause excessive pressure on a certain part of the wrist, leading to wrist fatigue and discomfort after prolonged wear, and may even leave marks on the wrist.

[0089] Please see Figure 7 In one alternative embodiment, the two receiving slots 101 are arranged symmetrically about the axis of the main body 100.

[0090] In this embodiment, the two receiving slots 101 are symmetrically arranged about the axis of the main body 100. When both receiving slots 101 contain earphones, the two earphones are symmetrically arranged about the axis of the main body 100. This ensures that the appearance of the wearable device remains consistent regardless of whether it is worn in the left or right hand, maintaining visual balance and enhancing the product's aesthetics. Of course, the two earphones can also be symmetrically arranged about the axis of the main body 100; this application does not impose this limitation.

[0091] Please see Figure 7 and Figure 8In one optional embodiment, the main body 100 includes a middle frame 150, which is annular, and a receiving groove 101 is disposed on the outer peripheral wall of the middle frame 150. The middle frame 150 and the receiving groove 101 are concentrically arranged.

[0092] In this embodiment, the concentric arrangement of the receiving slot 101 and the mid-frame 150 allows the earphones to better integrate into the overall shape of the mid-frame 150 after being housed in the receiving slot 101. That is, the mid-frame 150 and the earphones visually merge into one, rather than being simple additional components, eliminating a cluttered appearance. Furthermore, the concentric arrangement of the receiving slot 101 and the mid-frame 150 allows the earphones to fit snugly against the curved contour of the mid-frame 150, embedding themselves within the curved receiving slot 101 on the outer periphery of the mid-frame 150. This layout fully utilizes the limited space around the mid-frame 150, avoiding the additional lateral or vertical space that might be required with a non-concentric arrangement, thus making the entire smart host structure more compact. Of course, the mid-frame 150 and the receiving slot 101 can also be non-concentric; this application does not limit this.

[0093] Please see Figure 1 and Figure 2 In one optional embodiment, the main unit 100 includes a display screen 140, a middle frame 150, and a shell body 160. The shell body 160 is formed within the middle frame 150 along its circumference. The display screen 140 is disposed in the shell body 160, and a first groove 103 is disposed in the shell body 160. For example, the shell body 160 may include a detachably connected upper shell 161 and a lower shell 162, with the display screen 140 disposed in the upper shell 161.

[0094] Because the total depth of the receiving groove 101 and the first groove 103 is relatively large, if both the receiving groove 101 and the first groove 103 were formed on the middle frame 150, the middle frame 150 would need to have a large size, which would increase the manufacturing cost of the middle frame 150 and the wearable device. Therefore, in this embodiment, the receiving groove 101 is located on the middle frame 150, and the first groove 103 is located on the shell body 160. This reduces the size of the middle frame 150, thereby reducing the manufacturing cost of the middle frame 150 and the wearable device. Of course, the first groove 103 can also be located on the middle frame 150, and this application does not limit this.

[0095] Please see Figure 3 In one optional embodiment, the outer peripheral wall of the main body 100 has a guide surface 105, which is in contact with the inner wall of the first groove 103. The guide surface 105 is used to guide the earphone into the receiving groove 101. For example, the guide surface 105 can be a guide plane or a guide arc surface or other guide curved surface.

[0096] In this embodiment, the guide surface 105 can form a horn-shaped structure. When the earphone is close to the main body 100, even if the position of the earphone is slightly off, the offset angle of the earphone can be corrected. The user can slide the earphone into the receiving slot 101 without precise alignment, simplifying the difficulty of inserting the earphone into the receiving slot 101.

[0097] Generally, when a user inserts the earphone into the receiving slot 101, the earpiece 230, being larger in size, will enter the receiving slot 101 first. In other words, if the earphone's position shifts, the earpiece 230 will interfere with the mid-frame 150 first. Therefore, in a further embodiment, the guide surface 105 is located on one side of the receiving slot 101 along its circumferential direction, and the guide surface 105 is in contact with the end wall of the receiving slot 101 near the first end of the receiving slot 101. This facilitates guiding the earpiece 230 into the first end of the receiving slot 101, so that the entire earphone can be inserted into the receiving slot 101.

[0098] In one optional embodiment, the main body 100 includes a middle frame 150, which is annular, and a receiving groove 101 is provided on the outer peripheral wall of the middle frame 150.

[0099] The curvature of the receiving groove 101 is a perfect circle. After the accessory 200 is installed into the receiving groove 101, the perfect circle curvature of the receiving groove 101 fits the shape of the accessory 200 very well, allowing the accessory 200 to be tightly embedded in the receiving groove 101, reducing shaking and loosening. Furthermore, the perfect circle curvature of the receiving groove 101 can make full use of the arc-shaped space on the outer periphery of the middle frame 150, making the embedding of the accessory 200 more natural.

[0100] And / or, the circumferential extension length of the receiving groove 101 is one-quarter to one-half of the perimeter of the outer edge of the middle frame 150, thus providing sufficient space for the accessory 200 to ensure that the accessory 200 can be fully embedded in the receiving groove 101 for good storage and fixation. For example, the circumferential extension length of the receiving groove 101 may be one-third of the perimeter of the outer edge of the middle frame 150.

[0101] And / or, the diameter of the outer edge of the middle frame 150 is 40mm to 55mm, and the circumferential extension length of the receiving groove 101 is 45mm to 61mm. For example, the diameter of the outer edge of the middle frame 150 can be 42mm, 45mm, 47mm, 50mm, 53mm, etc.; the circumferential extension length of the receiving groove 101 can be 47mm, 51mm, 53mm, 56mm, 60mm, etc.

[0102] In this embodiment, the outer edge diameter of the middle frame 150 is between 40mm and 55mm, which conforms to the wrist size of most people. It avoids affecting wearing comfort due to being too large or too small. This size provides sufficient display area without causing excessive pressure on the wrist. The circumferential extension length of the receiving slot 101 is between 45mm and 61mm, providing sufficient space for the accessory 200 to ensure that the accessory 200 can be fully embedded in the receiving slot 101, achieving good storage and fixation.

[0103] Please see Figure 9 and Figure 10 In one optional embodiment, the main body 100 is provided with a first docking portion 110 and a second docking portion 120 for connecting with the connecting strap 300 of the wearable device, and the first docking portion 110 and the second docking portion 120 are respectively located on opposite sides of the main body 100.

[0104] The main unit 100 includes a display screen 140, which is strip-shaped, and the length direction of the display screen 140 is ( Figure 9 and Figure 10 The direction indicated by the arrow in the middle (x) and the arrangement direction of the first docking part 110 and the second docking part 120 ( Figure 9 and Figure 10 The direction indicated by the arrow y) is at a preset angle, which is greater than 0° and less than or equal to 90°. That is, the length direction of the display screen 140 is inclined relative to the arrangement direction of the first docking portion 110 and the second docking portion 120, or the length direction of the display screen 140 is perpendicular to the arrangement direction of the first docking portion 110 and the second docking portion 120. It should be noted that the preset angle is the minimum angle between the straight line containing the length direction of the display screen 140 and the straight line containing the arrangement direction of the first docking portion 110 and the second docking portion 120. For example... Figure 9 and Figure 10 The angle indicated by angle α. For example, the preset angle can be 5°, 10°, 20°, 30°, 50°, 70°, 80°, 85°, etc.

[0105] In this embodiment, when the preset angle between the length direction of the display screen 140 and the arrangement direction of the first docking portion 110 and the second docking portion 120 is greater than 0° and less than 90° (e.g. Figure 9As shown, the display screen 140 is tilted relative to the user's arm in both its length and width directions. Therefore, the user only needs to rotate their arm or head by a small angle to make the length or width of the display screen 140 roughly aligned with the user's line of sight, conforming to the user's viewing habits and making it easier for the user to view the display screen 140, thus improving the user experience. In addition, in some usage scenarios, such as cycling, exercising, or typing at work, the user's arm is naturally tilted relative to the user's body. In these cases, the user does not need to raise their arm horizontally to view the display screen 140 naturally, thereby improving the user experience.

[0106] When the preset angle between the longitudinal direction of the display screen 140 and the arrangement direction of the first docking portion 110 and the second docking portion 120 is 90°, the display screen 140 is more in line with human visual habits when worn. When people view wearable devices such as watches, they are usually more accustomed to browsing information horizontally. This layout allows users to view the content on the display screen 140, such as time, notifications, and health data, more naturally and comfortably without turning their wrists or heads.

[0107] Furthermore, with the structure of this embodiment, the two ends of the display screen 140 along its own length direction will avoid the first docking part 110 and the second docking part 120. In this way, the space below the display screen 140 can be used to arrange components, such as headphones. And arranging components using the space below the display screen 140 will not interfere with the docking structure of the first docking part 110 and the connecting strip 300, nor with the docking structure of the second docking part 120 and the connecting strip 300.

[0108] In one optional embodiment, the preset angle is 30° to 60°. For example, the minimum included angle can be 32°, 35°, 38°, 42°, 43°, 45°, 50°, 53°, 55°, 58°, etc., and this application does not limit it.

[0109] In this embodiment, the preset included angle is controlled between 30° and 60°. This not only ensures that the size of the minimum included angle is within a suitable range, but also that the size of the complementary angle of the minimum included angle is within a suitable range. This not only increases or decreases the degree of rotation angle of the user's arm, but also ensures 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.

[0110] This application also discloses an accessory for use in a wearable device. The wearable device includes a main body 100, and the accessory 200 is arc-shaped and detachably disposed within an arc-shaped receiving groove 101 on the outer peripheral wall of the main body 100. The accessory 200 can engage with the main body 100 in a circumferential upper limit. It should be noted that the main body 100 here can be the main body of any of the above embodiments.

[0111] After the accessory 200 of this application is placed in the receiving groove 101 of the main body 100, the main body 100 can not only restrict the end of the accessory 200, but also limit the accessory 200 by utilizing the shape matching between the accessory 200 and the receiving groove 101. This disperses the stress on the accessory 200, prevents stress concentration, and reduces the risk of damage to the accessory 200. It should be noted that the end of the accessory 200 is the portion extending circumferentially from the end face of the accessory 200 along a predetermined distance. The predetermined distance can be 2cm, 3cm, etc., and can be selected according to the actual situation.

[0112] In one optional embodiment, the accessory 200 is an earphone, which includes a connected earpiece portion 230 and a handle portion 240, the handle portion 240 being arc-shaped. Specifically, the earpiece portion 230 contains a sound-emitting module capable of emitting sound, and the end of the handle portion 240 is connected to the sound-emitting module for use by the user. In this embodiment, along the depth direction of the receiving groove 101, the size of the earpiece portion 230 is larger than the size of the handle portion 240. Therefore, in this embodiment, a first groove 103 is formed at one end of the receiving groove 101 to accommodate the portion of the earpiece portion 230 that extends beyond the receiving groove 101.

[0113] In this embodiment, compared to the zigzag-shaped handle portion 240, the arc-shaped handle portion 240 of this application fits the user's ear better, improving wearing comfort. For example, the handle portion 240 may include a rotatably connected body and an ear-clamping arm. Both the body and the ear-clamping arm are arc-shaped. The ear-clamping arm can rotate between a first position and a second position. In the first position, the ear-clamping arm is concentrically positioned with the body; in the second position, an ear-clamping space is formed between the ear-clamping arm and the body, and the user's ear is located within the ear-clamping space. The ear-clamping arm and the body together clamp the ear, fixing the earphone to the ear.

[0114] In some embodiments, accessory 200 may also include at least one of a power bank, a speaker, a camera module or a blood pressure measuring pump module, and accessory 200 receiving slot 101 is used to accommodate accessories 200 with different functions according to different needs.

[0115] This application also discloses a smart host, including a host body 100 as described in any of the above embodiments and an accessory as described in any of the above embodiments. The accessory 200 is detachably installed in a receiving groove 101. The shape of the receiving groove 101 is adapted to the shape of the portion of the accessory 200 located within the receiving groove 101. Along the circumference of the host body 100, the end of the accessory 200 is positioned and engaged with the host body 100. For example, the host body 100 includes a first magnetic element, and the accessory 200 includes a second magnetic element. The host body 100 and the accessory 200 can achieve the purpose of detachably installing the accessory 200 in the receiving groove 101 through the cooperation of the first and second magnetic elements. Here, the first magnetic element can be a magnet or an energized coil, and the second magnetic element can also be a magnet or an energized coil.

[0116] After the accessory 200 of this application is placed in the receiving groove 101 of the main body 100, the main body 100 can not only restrict the end of the accessory 200, but also limit the accessory 200 by using the shape matching between the accessory 200 and the receiving groove 101. In this way, the stress on the accessory 200 can be distributed, stress concentration can be prevented, and the risk of damage to the accessory 200 can be reduced.

[0117] Please see Figure 1 and Figure 2 In one alternative embodiment, a portion of the accessory 200 protrudes from the receiving groove 101 along the depth direction of the receiving groove 101, so that the user can remove the accessory 200 from the receiving groove 101 by taking the portion of the accessory 200 protruding from the receiving groove 101, thereby improving the ease of use of the wearable device.

[0118] The accessory 200 includes a first housing 210 and a second housing 220 distributed along the depth direction of the receiving groove 101. The first housing 210 and the second housing 220 are connected. For example, the first housing 210 and the second housing 220 can be connected by means of snap-fit, screw connection, adhesive bonding, etc. The mating gap 201 between the first housing 210 and the second housing 220 is located within the receiving groove 101. It should be noted that the mating gap 201 here refers to the gap formed between the first housing 210 and the second housing 220 after the separately configured first housing 210 and the second housing 220 are connected.

[0119] In this embodiment, the first housing 210 and the second housing 220 are connected in a mating manner. The mating gap 201 between the first housing 210 and the second housing 220 is located within the receiving groove 101. This allows the receiving groove 101 to conceal the mating gap 201, meaning the mating gap 201 is not exposed outside the receiving groove 101. This design not only ensures the aesthetic integrity of the wearable device but also utilizes the sidewalls of the receiving groove 101 to block dust from the environment, reducing the risk of dust entering the accessory 200 through the mating gap 201. Therefore, this embodiment can improve the ease of use of the wearable device while reducing the risk of dust entering the accessory 200.

[0120] This application also discloses a wearable device, including the smart host described in any of the above embodiments, so that the wearable device has the beneficial effects of any of the above embodiments, which will not be described in detail here. For example, the wearable device may include a connecting strap 300, the two ends of which are respectively connected to the first docking part 110 and the second docking part 120.

[0121] The foregoing embodiments of this application focus on describing the differences between various embodiments. 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. Those skilled in the art, under the guidance of this application, can make many modifications without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
