[0038] In order to make the technical solutions and advantages of the present application clearer, the implementation methods of the present application will be described in further detail below with reference to the accompanying drawings.

[0039] At present, with the development of science and technology, wearable devices have become commonly used electronic devices.

[0040] Wearable devices are portable devices that can be worn on the body or integrated into clothing or accessories. Smart bracelets are the most popular type of wearable device. With smart bracelets, users can record real-time data such as exercise, sleep, and food intake in their daily lives, and synchronize this data with mobile devices, helping to guide healthy living through data.

[0041] Many smart wristbands on the market feature a detachable design, allowing the wristband body to be removed from the housing. By pairing the wristband body with different housings, the wristband body can be worn not only as a wristband but also as a running bean on clothing or shoes. However, to remove the wristband body from the housing, existing smart wristbands often require the user to use a fingernail or a pick to insert between the wristband body and the housing to remove the wristband body from the housing. This is inconvenient and can easily cause bumps and damage to the wristband body, affecting the user experience.

[0042] In response to the above technical problems, an embodiment of the present application provides a shell assembly 1.

[0043] like Figure 1 As shown, the shell assembly 1 includes a first shell 11, the first shell 11 is provided with a cavity 111, the cavity 111 has an opening 1111, and a recessed portion 1112 is provided at one end of the bottom wall of the cavity 111, wherein the bottom wall of the cavity 111 is arranged opposite to the opening 1111, and the recessed portion 1112 is recessed toward the side away from the opening 1111.

[0044] The housing assembly 1 is applied to electronic devices or other devices requiring detachable connection between a housing and accessories. For example, the electronic device is a wearable device, including but not limited to a wristband, a watch, a belt, an earphone, an anklet, and the like.

[0045] like Figure 1 As shown, an opening 1111 is provided at the top of the first shell 11, and the cavity 111 is suitable for accommodating accessories of the electronic device. This application takes the electronic device as a smart bracelet as an example for explanation. The electronic device includes a device body 2, and the device body 2 is integrated with electronic accessories such as sensors, processors, display modules, batteries, and circuit boards. The device body 2 is detachably arranged in the cavity 111, and the shape of the device body 2 is adapted to the shape of the cavity 111. The device body 2 can be inserted into the cavity 111 from the opening 1111, and can also be detached from the cavity 111 from the opening 1111.

[0046] The recessed portion 1112 is located at one end of the cavity 111 . Exemplarily, the recessed portion 1112 is located at one end in the length direction of the cavity 111 , making it convenient for the user to press and apply force to the device body 2 in the cavity 111 .

[0047] If the user needs to remove the device body 2 from the cavity 111, he only needs to press the device body 2 at the opening 1111 so that one end of the device body 2 is buckled into the recessed portion 1112 and abuts against the bottom wall of the recessed portion 1112. According to the principle of leverage, with the connection between the recessed portion 1112 and the bottom wall of the cavity 111 as the fulcrum, the other end of the device body 2 will tilt upward, and the user can easily remove the device body 2 from the cavity 111 along the tilted end of the device body 2. Compared with the traditional disassembly method, the shell assembly 1 provided in the embodiment of the present application can not only remove the device body 2 more conveniently and quickly, but also is less likely to cause bumps and damage to the device body 2.

[0048] The cross-sectional shape of the cavity 111 is circular, oval, rectangular, or other polygonal. The embodiment of the present application uses the oval cross-sectional shape of the cavity 111 as an example for description. It is understood that the cross-sectional shape of the cavity 111 is a cross-sectional shape obtained by cutting it with a plane perpendicular to the height direction of the first shell 11.

[0049] Exemplarily, the depth of the recessed portion 1112 is 15% to 25% of the total height of the cavity 111 , and the length of the recessed portion 1112 is 20% to 30% of the total length of the cavity 111 .

[0050] The shell assembly 1 provided in the embodiment of the present application has a recessed portion 1112 set at one end of the bottom wall of the cavity 111. When the user wants to remove the accessory in the cavity 111 from the cavity 111, he only needs to press the accessory at the opening 1111 to make one end of the accessory enter the recessed portion 1112. The lever principle can be used to make the other end of the accessory rise and detach from the cavity 111, which is convenient for the user to remove the accessory from the cavity 111, greatly improving the disassembly efficiency of the electronic device and helping to enhance the user experience.

[0051] In a further embodiment, the recessed portion 1112 is in an arc shape, and the recessed portion 1112 is smoothly connected to the bottom wall and the inner side wall of the cavity 111 .

[0052] like Figure 1 As shown, the bottom wall of the recessed portion 1112 is smooth in shape, and the bottom wall of the recessed portion 1112 is smoothly connected with the bottom wall and inner wall of the cavity 111. When the user presses the device body 2, the device body 2 sinks into the recessed portion 1112 along the guidance of the arc surface, reducing the impact force on the device body 2 and preventing damage to the device body 2.

[0053] In a specific embodiment, the opening 1111 is retracted relative to the middle area of ​​the cavity 111 in the height direction.

[0054] like Figure 1As shown, the size of the opening 1111 is relatively small, while the size of the middle part of the cavity 111 is relatively large. This setting can better wrap the device body 2 in the first shell 11, play a certain limiting role on the device body 2, and prevent the device body 2 from escaping from the cavity 111 by itself.

[0055] In a further embodiment, the inner sidewall of the cavity 111 is in a curved shape.

[0056] like Figure 1 As shown, the sidewall of the cavity 111 is rounded and smoothly connected from the opening 1111 of the cavity 111 to the middle area in the height direction of the cavity 111 .

[0057] By setting the inner side wall of the cavity 111 to be an arc shape, it is convenient to install the device body 2 into the cavity 111, reducing the bumps and collisions suffered by the device body 2 in the cavity 111 during the installation process, and preventing the device body 2 from being damaged.

[0058] In a specific embodiment, the first shell 11 is a flexible member with elastic deformation capability.

[0059] Exemplarily, the first shell 11 is made of a material with certain flexibility and elastic deformation ability, such as silicone, rubber, etc.

[0060] Through this setting, the first shell 11 has better covering properties, thereby better wrapping the device body 2 and preventing the device body 2 from escaping from the cavity 111 on its own; at the same time, it reduces the extrusion of the device body 2 during installation and disassembly, preventing the device body 2 from being scratched.

[0061] In one embodiment, Figures 2 to 4 As shown, the shell assembly 1 also includes a second shell 12 and a clamping mechanism 13. The first shell 11 is connected to the second shell 12. The clamping mechanism 13 is located on the side of the second shell 12 away from the first shell 11. The first end of the clamping mechanism 13 is elastically connected to the second shell 12, and the second end of the clamping mechanism 13 can be connected to or separated from the second shell 12.

[0062] It can be understood that the first end and the second end of the clamping mechanism 13 are two opposite ends in the length direction of the clamping mechanism 13 .

[0063] like Figure 3 and Figure 4 As shown, the first shell 11 is connected to the top of the second shell 12 , and the clamping mechanism 13 is connected to the bottom of the second shell 12 , that is, the first shell 11 and the clamping mechanism 13 are respectively located on both sides of the second shell 12 .

[0064] By arranging the first end of the clamping mechanism 13 to be elastically connected to the second shell 12 , the clamping mechanism 13 can automatically spring open after the second end of the clamping mechanism 13 is separated from the second shell 12 .

[0065] For example, the first end of the clamping mechanism 13 is rotatably connected to the second housing 12, as shown in FIG. Figure 4 As shown, after the second end of the clamping mechanism 13 is separated from the second shell 12, the second end of the clamping mechanism 13 is opened at a certain angle relative to the second shell 12, making it convenient to place items such as clothes and shoelaces between the clamping mechanism 13 and the second shell 12.

[0066] Specifically, if Figure 3 As shown, there is a gap between the middle area between the two ends of the clamping mechanism 13 and the second shell 12. The clamping mechanism 13 and the second shell 12 can use the gap to clamp on both sides of items such as clothing and shoelaces. Then, the second end of the clamping mechanism 13 is connected to the second shell 12 to fix the shell assembly 1 on items such as clothing and shoelaces.

[0067] For example, the shell assembly 1 can be clamped on the shoelaces, so that the electronic device can be used as a running bean, wherein the running bean is also called a running dynamic sensor, which is used to detect data such as step frequency, stride, vertical amplitude, ground contact time, vertical stride ratio, left and right balance, and running power during running.

[0068] In a further embodiment, Figure 2 As shown, the clamping mechanism 13 includes a clamping plate 131 and a first elastic member 132. The first end of the clamping plate 131 is rotatably connected to the second housing 12, and the first elastic member 132 is respectively connected to the first end of the clamping plate 131 and the second housing 12. The housing assembly 1 also includes an adjustment member 14, which is telescopically disposed in the second housing 12 and is used to connect or disconnect with the second end of the clamping plate 131.

[0069] For example, Figure 2 As shown, a rotating shaft 122 is provided between the second shell 12 and the splint 131, thereby realizing a rotational connection between the second shell 12 and the first end of the splint 131. The first elastic member 132 is a torsion spring and is sleeved on the outer circumference of the rotating shaft 122. The two ends of the first elastic member 132 extend to form straight segments, one of which abuts against the second shell 12, and the other abuts against the splint 131, thereby realizing an elastic connection between the second shell 12 and the splint 131. After the second end of the clamping mechanism 13 is separated from the second shell 12, under the elastic force of the first elastic member 132, the splint 131 can rotate relative to the second shell 12, thereby automatically popping open, thereby opening a certain angle between the splint 131 and the second shell 12.

[0070] Exemplarily, the adjusting member 14 can be telescopically extended along the length direction of the second shell 12, and can be extended or retracted relative to the outer wall of the second shell 12. The adjusting member 14 can be connected to or separated from the second end of the splint 131 through its own telescopic movement. For example, when the user presses the adjusting member 14 to retract the adjusting member 14 relative to the outer wall of the second shell 12, the adjusting member 14 is separated from the second end of the splint 131.

[0071] Furthermore, if Figure 5 As shown, the shell assembly 1 also includes a second elastic member 15, and the second shell 12 is provided with an installation cavity 121. The second elastic member 15 and the adjusting member 14 are both arranged in the installation cavity 121. The second elastic member 15 is connected to the adjusting member 14 so that the adjusting member 14 can extend or retract into the installation cavity 121 relative to the installation cavity 121.

[0072] For example, the second elastic member 15 is a spring and can be deformed in its own length direction. Figure 5 As shown, the adjusting member 14 is partially located in the mounting cavity 121 , and the adjusting member 14 is connected to one end of the second elastic member 15 in the length direction.

[0073] Specifically, when the user presses the adjusting member 14 , the adjusting member 14 compresses the second elastic member 15 , and the adjusting member 14 retracts into the mounting cavity 121 ; when the user releases the adjusting member 14 , the adjusting member 14 extends relative to the mounting cavity 121 under the rebound action of the second elastic member 15 .

[0074] Furthermore, if Figures 5 to 8 As shown, a hook portion 141 is provided at one end of the adjusting member 14 close to the second elastic member 15, a connecting portion 1311 is protruded from the second end of the splint 131, and a flange 13111 is provided on the top of the connecting portion 1311 extending toward the first end of the splint 131, and a slot 1312 is formed between the connecting portion 1311 and the top wall of the splint 131, and the slot 1312 is used to accommodate the hook portion 141 so that the hook portion 141 is hooked with the connecting portion 1311.

[0075] It can be understood that the top of the connecting portion 1311 is the end of the connecting portion 1311 close to the second shell 12, the top wall of the clamping plate 131 is the side surface of the clamping plate 131 close to the second shell 12, and the connecting portion 1311 protrudes outward relative to the top wall of the clamping plate 131.

[0076] like Figure 5As shown, the hook portion 141 and the connecting portion 1311 are both "L"-shaped. When the hook portion 141 is accommodated in the slot 1312, the hook portion 141 is hooked with the connecting portion 1311, thereby connecting the second end of the splint 131 to the second shell 12; when the hook portion 141 is separated from the slot 1312, the hook portion 141 is separated from the connecting portion 1311, thereby separating the second end of the splint 131 from the second shell 12.

[0077] Specifically, when the hook portion 141 is accommodated in the slot 1312, if the user presses the adjusting member 14, the adjusting member 14 moves along its own length direction and compresses the second elastic member 15, and the adjusting member 14 retracts into the mounting cavity 121 and disengages from the slot 1312. At this time, the splint 131 is separated from the second shell 12, making it convenient for the user to remove the shell assembly 1 from items such as clothing and shoelaces; subsequently, if the user wants to clamp the shell assembly 1 on items such as clothing and shoelaces, he only needs to press the shell assembly 1 or the device body 2 in the cavity 111 so that the second end of the splint 131 is close to the second shell 12 and the hook portion 141 slides into the slot 1312, so that the second end of the splint 131 and the second shell 12 can be connected, and items such as clothing and shoelaces can be clamped in the gap 123 between the second shell 12 and the splint 131.

[0078] Furthermore, if Figure 7 and Figure 8 As shown, the end of the hook portion 141 is provided with a first inclined surface 1411 , and the flange 13111 is provided with a second inclined surface 13111 a adapted to the first inclined surface 1411 .

[0079] The first inclined surface 1411 and the second inclined surface 13111 a are adapted to each other, which means that the first inclined surface 1411 and the second inclined surface 13111 a have the same inclination angle and can fit together.

[0080] By setting the first bevel 1411 and the second bevel 13111a, when the second end of the splint 131 is separated from the second shell 12, when the user presses the shell assembly 1 to make the second end of the splint 131 close to the second shell 12, the first bevel 1411 of the hook portion 141 can fit with the second bevel 13111a, and under the guidance of the second bevel 13111a, the hook portion 141 moves along its own length direction and approaches the slot 1312, and then the hook portion 141 separates from the flange 13111 and extends into the slot 1312 under the action of the second elastic member 15, thereby realizing the connection between the second end of the splint 131 and the second shell 12.

[0081] In a specific embodiment, the steps of installing the shell assembly 1 include:

[0082] (1) Figure 9As shown in Figure (a), the device body 2 is pressed into the cavity 111 of the first shell 11 along the direction of the arrow;

[0083] (2) Figure 9 As shown in FIG. 1 ( b ), the adjusting member 14 is pressed to open the splint 131 ;

[0084] (3) Figure 9 As shown in Figure (c) in the figure, pass the splint 131 under the shoelaces, press the shell assembly 1 or the device body 2 to connect the second shell 12 and the splint 131.

[0085] In a specific embodiment, the steps of disassembling the shell assembly 1 include:

[0086] (1) Figure 10 As shown in FIG. 1 (d), the adjusting member 14 is pressed to open the splint 131 and the shell assembly 1 is removed from the shoelace;

[0087] (2) Figure 10 As shown in Figure (e), press one end of the device body 2 in the direction of the arrow to make the other end of the device body 2 tilt upward;

[0088] (3) Figure 10 As shown in Figure (f), hold the raised side in the direction of the arrow to remove the device body 2 from the cavity 111, so that the device body 2 is separated from the shell assembly 1.

[0089] An embodiment of the present application also provides an electronic device, which includes a device body 2 and a shell assembly 1 provided in any of the above embodiments. The cavity 111 of the shell assembly 1 is used to accommodate the device body 2. When one end of the device body 2 close to the recessed portion 1112 is pressed, the end of the device body 2 away from the recessed portion 1112 is tilted up.

[0090] Exemplarily, the electronic device is a wearable device, including but not limited to a wristband, watch, belt, earphones, anklet, etc. For example, the electronic device is a running bean, which can detect running data such as cadence, stride length, vertical oscillation, ground contact time, vertical stride ratio, left-right balance, and running power.
