Detailed implementation manners

[0030] The embodiments of the present invention disclose a wearable device to improve the antenna clearance requirements and ensure the antenna radiation efficiency.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0032] Please refer toFigures 1-8 , Figure 1 Exploded structural schematic diagram of the device body of a wearable device according to a specific embodiment of the present invention; Figure 2 Cross-sectional structural schematic diagram of the connection between the device body and the strap of the wearable device; Figures 3-8 Partial enlarged schematic diagrams of each component.

[0033] In a specific embodiment, the wearable device provided by the present invention includes a device body and a strap 6 connected to the device body.

[0034] Among them, the strap 6 is used to wear the device body at the corresponding position of the user, such as wearing the device body on the user's wrist as a watch or a bracelet. The specific structure of the strap 6 can refer to the prior art based on the connection method of the device body, and will not be elaborated here.

[0035] The device body includes an upper shell 2 and a lower shell 3, which are fixedly connected. The lower shell 3 refers to the shell at the end of the device body that contacts the user's skin in the wearing state, and the upper shell 2 is the shell at the opposite end. When the wearable device has a lens 1, the lens 1 is fixed inside the upper shell 2. Specifically, a lens 1 installation groove can be opened on the upper shell 2, and the lens 1 can be fixed in the lens 1 installation groove by methods such as dispensing. The specific fixed connection method between the upper shell 2 and the lower shell 3 can be screw connection, snap connection, etc., which will not be specifically limited here. An inner cavity is formed between the upper shell 2 and the lower shell 3, and components such as a circuit board and a battery that meet the functions of the wearable device are installed in the inner cavity. The specific settings can refer to the corresponding structures of conventional wearable devices such as watches and bracelets, and will not be elaborated here.

[0036] The upper shell 2 includes an upper main body portion 22 and upper protruding portions 21 at both ends of the upper main body portion 22. The lower shell 3 includes a lower main body portion 32 that cooperates with the upper main body portion 22 and lower protruding portions 31 at both ends of the lower main body portion 32. The upper protruding portions 21 and the lower protruding portions 31 cooperate and are fixedly connected to the strap 6. The upper shell 2 and the lower shell 3 are specifically an integral structure. The upper main body portion 22 and the lower main body portion 32 cooperate, and specifically an inner cavity for installing various components is formed between them. A lens 1 installation groove can be opened on the upper main body portion 22 and the lens 1 can be fixedly installed. The upper protruding portions 21 extend from opposite ends of the upper main body portion 22, and the lower protruding portions 31 extend from opposite ends of the lower main body portion 32. When the wearable device is a watch, the upper protruding portions 21 and the lower protruding portions 31 generally correspond to the 12 o'clock and 6 o'clock directions. The cooperation between the upper protruding portions 21 and the lower protruding portions 31 and the fixed connection to the strap 6 include the fixed connection between the upper protruding portion 21 and the strap 6, and the lower protruding portion 31 is fixed below the upper protruding portion 21; it also includes the fixed connection between the lower protruding portion 31 and the strap 6, and the upper protruding portion 21 is fixed above the lower protruding portion 31; it also includes the fixed connection between the upper protruding portion 21 and the lower protruding portion 31, and the strap 6 is fixed at the connection between the two, that is, the strap 6 is fixedly connected to both the upper protruding portion 21 and the lower protruding portion 31.

[0037] The upper shell 2 and the lower shell 3 adopt the above structure, that is, the surface of the housing of the device main body extending from the connection positions with the belt body 6 at both ends to the middle and joining is used as the parting surface, and the whole housing is divided into the upper shell 2 and the lower shell 3. In other words, the housing includes a main body part and protruding parts connected to both ends of the main body part and connected to the belt body 6. The lens 1 is fixed on the main body part, then the housing is integrally divided into the upper shell 2 and the lower shell 3 from the middle of the protruding parts and the middle of the main body part. Of course, the middle here refers to the part between the upper and lower surfaces of the housing, not limited to the midline.

[0038] The upper shell 2 is an overall metal shell and is used as the antenna of the wearable device, that is, the upper shell 2 is used as the antenna. For the specific connection relationship between the upper shell 2 as the antenna and the circuit board, etc., please refer to the prior art and will not be elaborated here. That is, in this application, the antenna is used as the upper shell 2, and the structure and principle of the antenna to realize the radiation function, etc., can all adopt the conventional antenna settings. The lower shell 3 is made of insulating material. Since the lower shell 3 has a lower protruding part 31 and a lower main body part 32, when the user wears it, the upper shell 2 can be separated from the user's skin, thereby improving the antenna clearance requirement. Specifically, the material of the lower shell 3 can adopt the conventional insulating material in the prior art, and can be set accordingly in combination with the requirements of the wearable device for the strength, hardness, etc. of the housing, and no specific limitation is made here.

[0039] Applying the wearable device provided by the present invention, the upper shell 2 and the lower shell 3 are integrally divided from the connection position with the belt body 6. Thus, when the user wears it, the lower protruding part 31 separates the upper protruding part 21 from the user's skin. Since the lower shell 3 is an overall insulating material, it avoids the upper protruding part 21 from contacting and conducting with the skin. Therefore, the upper shell 2 is an overall metal shell and can be used as a metal antenna, and combined with the insulating effect of the lower shell 3, the antenna clearance requirement is improved. In summary, by adopting this wearable device, through the reasonable parting of the upper shell 2 and the lower shell 3, and directly using the upper shell 2 as the metal antenna, the antenna is less restricted by space, which is beneficial to ensuring the antenna radiation efficiency.

[0040] Specifically, the upper protruding part 21 and the lower protruding part 31 are fixedly connected to fix the upper shell 2 and the lower shell 3. The upper shell 2 and the lower shell 3 are fixedly connected, and specifically, it can be realized through the fixed connection between the upper protruding part 21 and the lower protruding part 31. If the upper protruding part 21 and the lower protruding part 31 are connected by screws 4, then the upper shell 2 and the lower shell 3 are integrally fastened. Such a setting avoids the occupation of the internal space of the upper main body part 22 and the lower main body part 32 by the fixed connection structure, and further reserves a larger space for the layout of each component.

[0041] In order to achieve the precise positioning of the upper shell 2 and the lower shell 3, a positioning groove 33 is provided in one of the upper protruding portion 21 and the lower protruding portion 31, and the other has a positioning protrusion 23 that is inserted into the positioning groove 33 for positioning. During assembly, the positioning protrusion 23 is inserted into the positioning groove 33. Through the precise positioning of the upper shell 2 and the lower shell 3, it is convenient for their subsequent fixed connection, and the precise fit of the upper shell 2 and the lower shell 3 ensures the appearance effect of the device main body. Specifically, the positioning protrusion 23 can be provided on the upper protruding portion 21, and the positioning groove 33 can be provided on the lower protruding portion 31. Of course, according to needs, the setting positions of the positioning protrusion 23 and the positioning groove 33 can also be swapped. It should be noted that since the positioning protrusion 23 and the positioning groove 33 cooperate for positioning, their shapes should be correspondingly set. For example, when the positioning groove 33 is a rectangular groove, the positioning protrusion 23 is a rectangular protrusion with dimensions consistent with those of the rectangular groove, so as to achieve effective positioning in all directions. At the same time, the positioning groove 33 and the positioning protrusion 23 are provided on the upper protruding portion 21 and the lower protruding portion 31, without occupying the inner cavity space. In order to achieve a better positioning effect, the upper protruding portion 21 located at both ends of the upper main body portion 22 and the lower protruding portion 31 located at both ends of the lower main body portion 32 are both provided with a matching positioning groove 33 and positioning protrusion 23, so as to achieve precise positioning from both ends of the upper shell 2 and the lower shell 3, with higher positioning accuracy. Of course, according to needs, the positioning groove 33 and the positioning protrusion 23 can also be provided only on the upper protruding portion 21 and the lower protruding portion 31 on one side.

[0042] Furthermore, the positioning protrusion 23 and the bottom of the positioning groove 33 are connected by a screw 4. During assembly, after the positioning protrusion 23 is inserted into the positioning groove 33, the positioning protrusion 23 is locked in the positioning groove 33 by the screw 4, thereby realizing the fixation of the upper shell 2 and the lower shell 3. With this setting, the assembly operation is simple, the structure is simple, and the connection is reliable. Preferably, the positioning protrusion 23 is provided on the lower end face of the upper protruding portion 21 facing the lower protruding portion 31, and the positioning groove 33 is provided on the upper end face of the lower protruding portion 31 facing the upper protruding portion 21. Then the bottom of the positioning groove 33 is located at the bottom of the lower protruding portion 31. Thus, after the screw 4 is connected to the bottom of the positioning groove 33 and the positioning protrusion 23, the head of the screw 4 is located at the bottom of the lower protruding portion 31, which will not affect the appearance of the upper shell 2, and when the user wears it, the screw 4 is not easily loosened by external force.

[0043] Even further, a through hole 34 is provided at the bottom of the positioning groove 33. The size of the through hole 34 is smaller than the head size of the screw 4. The end of the positioning protrusion 23 has a screw post 24 that is inserted into the through hole 34. The screw post 24 has a screw hole, and the screw 4 is fixed to the screw hole and its head abuts against the outside of the through hole 34. As Figures 3-6As shown, the bottom of the positioning groove 33 has a through hole 34. The screw post 24 at the end of the positioning protrusion 23 is inserted into the through hole 34. The shape and size of the screw post 24 should be consistent with those of the through hole 34. For example, when the screw post 24 is cylindrical, the through hole 34 is a round hole with the same size. Then, the through hole 34 and the screw post 24 also play a role in precise positioning. Combined with the positioning of the positioning groove 33 and the positioning protrusion 23, the positioning of the upper shell 2 and the lower shell 3 is more precise. A screw hole is provided on the end face of the screw post 24, and the screw 4 is tightened into the screw hole. Since the head size of the screw 4 is larger than the size of the through hole 34, the head of the screw 4 is blocked by the wall surface around the through hole 34, thereby realizing the fixed connection between the upper extension part 21 and the lower extension part 31. Preferably, a groove 36 is provided on the end face of the bottom of the positioning groove 33 that faces away from the positioning groove 33. That is, one end of the through hole 34 communicates with the positioning groove 33, and the other end communicates with the groove 36. The head of the screw 4 is located in the groove 36, which not only avoids the exposure of the head of the screw 4, makes the overall structure of the upper shell 2 and the lower shell 3 more regular, but also can prevent the screw 4 from being accidentally stressed and loosened, making the connection between the upper shell 2 and the lower shell 3 more reliable.

[0044] Specifically, taking the example that the positioning protrusion 23 is provided on the lower end face of the upper extension part 21 facing the lower extension part 31, and the positioning groove 33 is provided on the upper end face of the lower extension part 31 facing the upper extension part 21, a groove 36 is provided on the lower end face of the lower extension part 31. The wall surface between the groove 36 and the positioning groove 33 has a through hole 34, and the through hole 34 connects the groove 36 and the positioning groove 33. The size of the through hole 34 is smaller than the size of the head of the screw 4. Thus, the screw post 24 is inserted into the through hole 34, and the screw 4 is fixed into the screw hole on the screw post 24, and the head of the screw 4 abuts against the outside of the through hole 34, that is, on the wall surfaces of the groove 36 and the positioning groove 33, thereby locking the upper shell 2 and the lower shell 3. Of course, when the screw 4 is used to lock the upper shell 2 and the lower shell 3, the stepped surfaces formed between the positioning groove 33 and the through hole 34 and between the positioning protrusion 23 and the screw post 24 should avoid interfering with the seamless connection of the upper shell 2 and the lower shell 3. The total length of the screw post 24 and the positioning protrusion 23 should not be greater than the total depth of the positioning groove 33 and the through hole 34 to avoid interfering with the seamless connection of the upper shell 2 and the lower shell 3.

[0045] In one embodiment, a waterproof double-sided tape is provided between the positioning groove 33 and the positioning protrusion 23. That is, while the positioning groove 33 and the positioning protrusion 23 are connected by the screw 4, high-level waterproofing can be achieved by setting a waterproof double-sided tape, that is, bonding through a waterproof bonding layer, such as meeting the 5ATM waterproof requirement.

[0046] In the above embodiments, the lower case 3 is a plastic case. Plastic has good insulation, which can reliably ensure the antenna clearance requirements. At the same time, plastic can be easily colored to meet the diverse color requirements of the wearable device case. Moreover, the plastic material has a good touch, providing a better experience for users when wearing. Of course, according to needs, the lower case 3 can also be made of other conventional insulating materials.

[0047] In the above embodiments, the upper extension 21 or the lower extension 31 has opposite spring bar holes 25 and is connected to the strap body 6 through a spring bar. Specifically, the upper extension 21 has opposite spring bar holes 25 and is fixedly connected to the strap body 6 through a spring bar, that is, the upper case 2 is fixedly connected to the strap body 6 through the upper extension 21. Since the upper case 2 is an overall metal case, it can reliably fix the strap body 6 in cooperation with the spring bar. According to needs, the lower case 3 can also be fixedly connected to the strap body 6 through the lower extension 31. The strap body 6 is connected to the device main body by a spring bar, with a simple structure and small space occupation. Of course, the connection between the strap body 6 and the device main body is not limited to the spring bar connection, and other connection methods such as snap fasteners can also be used.

[0048] A wearable device such as a watch generally has a button 5. Then, a button hole 35 is opened on the lower case 3, and the button 5 is hermetically connected inside the button hole 35. That is, the button 5 is hermetically installed inside the lower case 3. According to needs, the button hole 35 can also be partially opened on the upper case 2 and partially on the lower case 3, that is, the button hole 35 is opened at the connection between the lower case 3 and the upper case 2, and it can be specifically set according to space needs. A button FPC module can be arranged inside the lower case 3 to cooperate with the button 5. For its specific structure and the working principle of the button 5, etc., please refer to the prior art. In order to ensure the sealing performance, a button FPC double-sided tape can be set. The button hole 35 can be specifically set at the corresponding three o'clock position.

[0049] Specifically, the button 5 includes a head and a rod portion. A bushing is fixedly sleeved outside the rod portion, and the bushing is in interference fit with the button hole 35, and the head is located outside the button hole 35. The rod portion of the button 5 is fixed to the bushing, and the bushing is in interference fit with the button hole 35 and thus fixed. Moreover, the interference fit can simultaneously achieve the sealing effect, so that the button 5 is hermetically installed on the lower case 3 and the upper case 2.
