Description

Technical Field

[0001] This application relates to the field of wearable devices, and particularly to an intelligent host and a wearable device. Background Art

[0002] Intelligent wearable electronic products (such as smart watches, smart bracelets, etc.) are becoming increasingly popular and also integrate functions of calling and photographing to meet various usage requirements of users.

[0003] In related technologies, some intelligent wearable devices include a movable connection component separately connected to a host body and a bracket body. The movable connection component has a rotational connection component for connecting to the host body and a buckle component for connecting to the bracket body. When a user needs to make a call or take a photo, the user can remove the host body from the bracket body connected to the wristband through the movable connection component. In this way, the user does not need to always raise the arm during a call, and when using the host body to take a photo, there is no need to adjust the shooting angle by adjusting the position of the arm. When there is no need for calling and photographing, the host body is reinstalled on the bracket body to prevent loss.

[0004] However, in actual operation, when the user installs the host body on the bracket body, the rotational connection component and the buckle component need to be kept at a fixed angle. When there is a misalignment angle between the rotational connection component and the buckle component, installation cannot be carried out, resulting in that the user needs to first adjust the angle between the above components before installing the host body, reducing the convenience of using the intelligent wearable device for the user.

[0064] Such as Figure 1The following is a schematic structural diagram of an intelligent host 1, which includes a host body 40, a bracket body 10, a rotating connection assembly 30, and a locking assembly 20. An installation groove 101 is provided on the bracket body 10, and a plug-in groove 102 is provided on the groove wall of the installation groove 101; the locking assembly 20 includes a locking housing 21 and an elastic plug-in member 22 movably disposed within the locking housing 21. When the elastic plug-in member 22 is subjected to a force towards the inside of the locking housing 21, the elastic plug-in member 22 can retract into the locking housing 21. When the locking housing 21 is placed in the installation groove 101 and the elastic plug-in member 22 corresponds to the plug-in groove 102, the elastic plug-in member 22 can be reset to insert into the plug-in groove 102; the rotating connection assembly 30 is connected to the host body 40, and the rotating connection assembly 30 includes a first rotating shaft 31 extending into the locking assembly 20. The rotating connection assembly 30 is rotatably connected to the locking assembly 20 through the first rotating shaft 31. When the rotating connection assembly 30 rotates with the intelligent host 1, the first rotating shaft 31 is driven to rotate, and the first rotating shaft 31 drives the elastic plug-in member 22 to retract into the locking housing 21 to disengage from the plug-in groove 102, so that the host body 40 is detachable from the bracket body 10.

[0065] The intelligent host 1 provided by the embodiment of the present application includes a host body 40, a bracket body 10, a rotating connection assembly 30, and a locking assembly 20. The rotating connection assembly 30 and the locking assembly 20 are used to establish a detachable connection relationship between the host body 40 and the bracket body 10, wherein the rotating connection assembly 30 is respectively connected to the host body 40 and the locking assembly 20, and the locking assembly 20 is detachably disposed in the installation groove 101 of the bracket body 10, so that the host body 40 is detachable from the bracket body 10.

[0066] Please refer to Figure 2 , the locking assembly 20 includes a locking housing 21 and an elastic plug-in member 22, and the elastic plug-in member 22 can move within the locking housing 21. When the elastic plug-in member 22 is subjected to a force towards the inside of the locking housing 21, the elastic plug-in member 22 can retract into the locking housing 21. An installation groove 101 for accommodating the locking assembly 20 is provided on the bracket body 10, and a plug-in groove 102 is provided on the groove wall of the installation groove 101. When the locking housing 21 is placed in the installation groove 101 and the elastic plug-in member 22 corresponds to the plug-in groove 102, the elastic plug-in member 22 can be reset to insert into the plug-in groove 102, thereby connecting the locking assembly 20 to the bracket body 10, and further enabling the host body 40 to be stably installed on the bracket body 10.

[0067] The rotating connection assembly 30 is connected to the main body 40 of the host. The rotating connection assembly 30 includes a first rotating shaft 31 that rotates with the main body 40 of the host, and the first rotating shaft 31 is rotatably connected to the locking component 20. When the main body 40 of the host is in the initial state of being connected to the bracket body 10, the main body 40 of the host is in a state of being stacked on the bracket body 10. When the user needs to disassemble the main body 40 of the host from the bracket body 10, the user can rotate the main body 40 of the host. The main body 40 of the host drives the first rotating shaft 31 to rotate, and the first rotating shaft 31 can drive the elastic plug 22 in the locking component 20 to move towards the inside of the locking housing 21. When the first rotating shaft 31 rotates to a preset angle, the elastic plug 22 is completely separated from the plug slot 102, so that the main body 40 of the host can be disassembled from the bracket body 10.

[0068] Optionally, considering that a fitting gap may need to be reserved between the plug slot 102 and the elastic plug 22, the value of the preset angle is determined between 170° and 190°.

[0069] Specifically, the preset angle can be 170°, 172°, 174°, 176°, 178°, 180°, 182°, 184°, 186°, 188°, 190°, etc.

[0070] It should be noted that during the process of installing the buckle assembly 20 onto the bracket body 10, the force acting on the elastic insertion member 22 towards the inside of the buckle housing 21 can be the pressure exerted by the inner wall of the installation groove 101 on the elastic insertion member 22 towards the inside of the buckle housing 21 when the elastic insertion member 22 abuts against the inner wall of the installation groove 101 during the movement of the buckle assembly 20 into the installation groove 101. That is to say, during the process of installing the buckle assembly 20 onto the bracket body 10, it is not necessary to rotate the main body 40 of the host to drive the elastic insertion member 22 to move so as to separate the elastic insertion member 22 from the insertion groove 102. Instead, only by forming an abutment between the elastic insertion member 22 and the groove wall of the installation groove 101, the groove wall of the installation groove 101 can press the elastic insertion member 22 back into the buckle housing 21. When the buckle assembly 20 continues to move into the installation groove 101 and reaches the position corresponding to the elastic insertion member 22 and the insertion groove 102, the elastic insertion member 22 can be reset and inserted into the insertion groove 102, and then the buckle assembly 20 can be installed onto the bracket body 10. In the related art, the pin body of the buckle assembly that forms an insertion relationship with the bracket body needs to retract the buckle assembly when the buckle assembly and the rotational connection assembly are rotated to a fixed angle. Therefore, when assembling the main body of the host, it is necessary to adjust the angular relationship between the buckle assembly and the rotational connection assembly, first retract the pin body of the buckle assembly, and then continue to install the buckle assembly onto the bracket body. However, for the elastic insertion member 22 in the embodiment of the present application, when it is not driven by the first rotating shaft 31 to be pulled back into the buckle housing 21, the elastic insertion member 22 can remain in a state of partially protruding from the buckle housing 21. In this way, no matter what angle is formed between the buckle assembly 20 and the rotational connection assembly 30, the elastic insertion member 22 can be retracted into the inside of the buckle housing 21 by the pressure exerted by the groove wall of the installation groove 101, so that the buckle housing 21 can be successfully installed onto the bracket body 10, improving the convenience of installing the main body 40 of the host onto the bracket body 10.

[0071] Exemplarily, please refer to Figure 3 and Figure 4 , Figure 3 in which the rotational connection assembly 30 and the buckle assembly 20 are in a parallel state, and the first rotating shaft 31 is in an initial state without rotation. It can be understood that the rotation angle of the first rotating shaft 31 is 0°. Figure 4An angle approaching 90° is formed between the rotation connection component 30 and the latch component 20 in [the above situation], which can be understood as the rotation angle of the first rotating shaft 31 being 90°. In the above two states, the elastic insertion part 22 in the latch component 20 remains in a state where it partially protrudes from the latch housing 21. When it is necessary to insert the latch component 20 into the installation groove 101, the elastic insertion part 22 abuts against the inner wall of the installation groove 101, and the elastic insertion part 22 retracts into the latch housing 21, so that the latch housing 21 continues to move to a position corresponding to the elastic insertion part 22 and the insertion groove 102, and the elastic insertion part 22 resets to extend into the insertion groove 102.

[0072] Of course, during the process of installing the latch component 20 onto the bracket body 10, the force acting on the elastic insertion part 22 towards the inside of the latch housing 21 can also be the pulling force that the user rotates the main body 40 of the host to drive the first rotating shaft 31 to rotate a preset angle, and the first rotating shaft 31 drives the elastic insertion part 22 to move towards the inside of the latch housing 21, so as to pull the elastic insertion part 22 back to completely retract into the latch housing 21. The latch component 20 can be smoothly placed into the installation groove 101. When the latch housing 21 moves to a position corresponding to the elastic insertion part 22 and the insertion groove 102, the main body 40 of the host can be rotated continuously to release the pulling force of the first rotating shaft 31 on the elastic insertion part 22, and the elastic insertion part 22 can be reset and inserted into the insertion groove 102, so that the latch component 20 can be installed onto the bracket body 10.

[0073] Please refer to Figure 5 , the rotation connection component 30 rotates a preset angle along with the main body 40 of the host, for example: 180°, and the first rotating shaft 31 in the rotation connection component 30 also rotates a preset angle, so as to pull the elastic insertion part 22 back to completely retract into the latch housing 21. In this state, the latch component 20 can be installed into the insertion groove 102 more smoothly.

[0074] It can be seen from this that in the embodiment of the present application, by arranging the elastic insertion part 22 in the latch component 20, the user has two optional operations when installing the latch component 20 on the bracket body 10. The first optional operation can directly insert the latch component 20 into the installation groove 101 of the bracket body 10, and the elastic insertion part 22 is pressed back into the latch housing 21 by the groove wall of the installation groove 101 to realize the placement of the latch housing 21 into the installation groove 101; the second optional operation can rotate the main body 40 of the host to drive the first rotating shaft 31 to pull the elastic insertion part 22 back into the latch housing 21 to realize the installation of the latch component 20 into the installation groove 101, thereby improving the user experience.

[0075] It should be noted that in the related art, when the main body of the host is not installed in place and the pin body does not completely correspond to the insertion slot on the bracket body, if the main body of the host is rotated to make the first rotating shaft rotate, the pin body will continue to protrude and be stuck to the bracket body. If the first rotating shaft is rotated further, the risk of damage to the first rotating shaft will increase, thereby affecting the connection stability between the main body of the host and the bracket body, and even making it impossible to connect the main body of the host and the bracket body again. In the embodiment of the present application, since the lock assembly 20 is provided with an elastically insertable member 22 that can move, the elastically insertable member 22 can retract into the lock housing 21 when subjected to pressure. Even if the main body of the host 40 is not installed in place, that is, when the elastically insertable member 22 does not completely correspond to the insertion slot 102, the elastically insertable member 22 only abuts against the wall of the installation slot 101 and moves for a certain distance, which does not affect the rotation of the first rotating shaft 31 at all. And even if the first rotating shaft 31 continues to rotate, it only further retracts the elastically insertable member 22 into the lock housing 21, and there is no possibility of the elastically insertable member 22 being stuck to the wall of the installation slot 101. Thus, the risk of the first rotating shaft 31 being blocked and damaged when the main body of the host 40 is not installed in place is completely eliminated, and the connection stability between the main body of the host 40 and the bracket body 10 is improved.

[0076] In this way, the intelligent host 1 provided by the embodiment of the present application, by providing an elastically insertable member 22 that can move in the lock assembly 20, when the elastically insertable member 22 is subjected to a force towards the inside of the lock housing 21, the elastically insertable member 22 can retract into the lock housing 21, so that the lock assembly 20 can be smoothly installed on the bracket body 10 even when it forms an angular relationship with the rotational connection assembly 30. In addition, since the elastically insertable member 22 can retract into the lock housing 21 when subjected to pressure, even if the main body of the host 40 is not installed in place, it does not affect the continuous rotation of the first rotating shaft 31. Thus, the risk of the first rotating shaft being blocked is completely eliminated, and while improving the convenience of installing the main body of the host 40 on the bracket body 10, the connection stability between the main body of the host 40 and the bracket body 10 is also improved.

[0077] In another embodiment, a cam structure 311 is provided at one end of the first rotating shaft 31 extending into the lock assembly 20. The elastically insertable member 22 includes: a mounting portion 221 and a first elastic member 220. The mounting portion 221 is located in the axial direction of the first rotating shaft 31. A cam groove 224 cooperating with the cam structure 311 is provided on the mounting portion 221. An insertion portion 222 for inserting into the insertion slot 102 is formed at the end of the mounting portion 221 along the radial direction of the first rotating shaft 31. The mounting portion 221 drives the insertion portion 222 to retract into the lock housing 21 under the driving action of the cam structure 311, so that the insertion portion 222 is disengaged from the insertion slot 102; the first elastic member 220 can reset the mounting portion 221, so that the insertion portion 222 extends out of the lock housing 21.

[0078] Please refer back to Figure 2 and in combination with reference to Figure 6 and Figure 7 , one end of the first rotating shaft 31 extending into the latch assembly 20 is provided with a cam structure 311, which is used to drive the elastic plug-in member 22 to move. The other end of the first rotating shaft 31 is used to establish a connection with the main body 40 of the host. The cam structure 311 has a larger diameter than the first rotating shaft 31, so that the rotating connection assembly 30 has stronger structural strength, and thus has a more stable driving force when the cam structure 311 drives the elastic plug-in member 22 to move. The cam structure 311 and the first rotating shaft 31 can be integrally formed by injection molding or powder synthesis, so as to ensure the driving performance of the first rotating shaft 31 and the cam structure 311.

[0079] The elastic plug-in member 22 includes a mounting portion 221 that can be driven by the cam structure 311 and a first elastic member 220 for resetting the mounting portion 221. The mounting portion 221 is located in the axial direction of the first rotating shaft 31. A cam groove 224 for cooperating with the cam structure 311 is provided on the mounting portion 221. A plug-in portion 222 for plugging into the plug-in groove 102 is formed at the end of the mounting portion 221 along the radial direction of the first rotating shaft 31. The first elastic member 220 can abut against the mounting portion 221 and can be compressed and reset during the movement of the mounting portion 221.

[0080] Please refer to Figure 6 , during the process of the first rotating shaft 31 rotating a preset angle along with the main body 40 of the host, the cam structure 311 drives the mounting portion 221 to move towards the inside of the latch housing 21 and drives the plug-in portion 222 to retract into the latch housing 21, and the first elastic member 220 is compressed. At this time, the latch assembly 20 can be detached from the mounting groove 101. When the first rotating shaft 31 continues to rotate along with the main body 40 of the host, the cam structure 311 releases the drive of the mounting portion 221, that is, the cam structure 311 releases the pulling force on the mounting portion 221 towards the inside of the latch housing 21. The first elastic member 220 is reset and drives the mounting portion 221 to move so that the plug-in portion 222 extends out of the latch housing 21. The plug-in portion 222 can be kept in the state of extending out of the latch housing 21, and the latch assembly 20 can be reinstalled into the mounting groove 101 at any time.

[0081] Optionally, the first elastic member 220 is a spring or a spring sheet.

[0082] In this way, the cam structure 311 of the first rotating shaft 31 drives the mounting portion 221 to move, and the first elastic member 220 drives the mounting portion 221 to reset, so that the latch assembly 20 and the mounting groove 101 can be disconnected. And even when the latch assembly 20 is touched during the use of the main body 40 of the host and forms an angle with the main body 40 of the host and the rotating connection assembly 30 after the latch assembly 20 is detached from the bracket body 10, it does not affect reinstalling the latch assembly 20 into the mounting groove 101. There is no need to adjust the angle between the latch assembly 20 and the rotating connection assembly 30, which improves the convenience of installing the main body 40 of the host.

[0083] In another alternative embodiment, a first abutting portion 211 is formed in the latch housing 21. The mounting portion 221 includes a second abutting portion 226. The first abutting portion 211 and the second abutting portion 226 are arranged along the radial direction of the first rotating shaft 31. The inserting portion 222 is connected to the second abutting portion 226 and is located on the side of the second abutting portion 226 away from the first abutting portion 211. One end of the first elastic member 220 abuts against the first abutting portion 211, and the other end of the first elastic member 220 abuts against the second abutting portion 226.

[0084] In this embodiment, please refer back to Figure 2 and in combination with Figure 6 and Figure 7 A first abutting portion 211 can be provided inside the latch housing 21. The first abutting portion 211 is used to provide stable support for the first elastic member 220 so that the first elastic member 220 can generate elastic deformation. The first abutting portion 211 can be formed on the inner surface of the latch housing 21 close to the rotating connection assembly 30 and extend along the axial direction of the first rotating shaft 31 and into the inner space of the latch housing 21 respectively, so as to form an abutting relationship with the first elastic member 220 arranged radially along the first rotating shaft 31 inside the latch housing 21.

[0085] The mounting portion 221 is formed with a second abutting portion 226. A plugging portion 222 is formed on one side of the second abutting portion 226, and the other side of the second abutting portion 226 abuts against the second elastic member 232. That is, along the radial direction of the first rotating shaft 31, the plugging portion 222, the second abutting portion 226, the first elastic member 220 and the first abutting portion 211 are arranged in sequence. During the process that the mounting portion 221 moves towards the inside of the latch housing 21 under the drive of the cam structure 311, the plugging portion 222 and the first abutting portion 211 move towards the inside of the latch housing 21 together with the mounting portion 221. One end of the first elastic member 220 abuts against the first abutting portion 211. Therefore, the first elastic member 220 is compressed under the pressure of the second abutting portion 226.

[0086] When the cam structure 311 releases the drive of the mounting portion 221, that is, when the cam structure 311 releases the limit on the mounting portion 221, the first elastic member 220 can be reset. Therefore, the first elastic member 220 can drive the mounting portion 221 and the plugging portion 222 to move in the opposite direction, so that the plugging portion 222 extends out of the latch housing 21.

[0087] In addition, during the process that the mounting portion 221 is driven by the first elastic member 220 to move in the reverse direction, the side of the second abutting portion 226 where the plugging portion 222 is formed can also abut against the inner wall of the latch housing 21, thereby fixing the length of the plugging portion 222 extending out of the latch housing 21.

[0088] Optionally, a first receiving groove 227 is formed at the position of the mounting portion 221 corresponding to the first abutting portion 211. A groove wall of the first receiving groove 227 forms the second abutting portion 226. The first abutting portion 211 extends into the first receiving groove 227, and the first elastic member 220 is received in the first receiving groove 227.

[0089] Please refer to Figure 2 , a first receiving groove 227 is formed at the position of the mounting portion 221 corresponding to the first abutting portion 211. The groove wall of the first receiving groove 227 forms the second abutting portion 226. The first abutting portion 211 can extend into the first receiving groove 227. The first elastic member 220 is placed in the first receiving groove 227. One end of the first elastic member 220 abuts against the first abutting portion 211 extending into the first receiving groove 227, and the other end abuts against the groove wall of the first receiving groove 227, that is, the side of the second abutting portion 226 away from the plugging portion 222.

[0090] In this way, since the latch assembly 20 needs to be arranged in the installation groove 101, due to the volume limitation of the bracket body 10, the space inside the installation groove 101 is also very limited. Therefore, the internal space of the latch assembly 20 also needs to be compactly arranged. By arranging the first elastic member 220 in the first avoidance groove of the mounting portion 221, the overall structure of the elastic plugging member 22 is optimized, so that the latch assembly 20 can be miniaturized, and thus the smart host 1 can be further miniaturized.

[0091] Optionally, a guiding inclined surface is formed on the side of the plugging portion 222 away from the rotation connection assembly 30.

[0092] Please refer to Figure 3 and Figure 4 , during the installation of the latch assembly 20, it is usually inserted into the installation groove 101 from top to bottom. A guiding inclined surface can be formed on the surface of the plugging portion 222 on the side away from the rotation connection assembly 30. The side of the plugging portion 222 away from the rotation connection assembly 30 can be regarded as the side facing the bottom of the installation groove 101.

[0093] In this way, during the process of the insertion part 222 abutting against the groove wall of the installation groove 101, the user only needs to overcome the frictional force between the guiding inclined surface and the groove wall of the installation groove 101, and can move the buckle assembly 20 into the interior of the installation groove 101 without using too much thrust, and the insertion part 222 is retracted into the buckle housing 21 under the pressure of the groove wall of the installation groove 101, reducing the obstruction and impact force during the insertion of the buckle assembly 20 into the installation groove 101 and improving the smoothness of the installation process.

[0094] In order to ensure the driving of the installation part 221 by the cam structure 311, so that the first rotating shaft 31 can rotate a preset angle in the initial state to retract the insertion part 222 into the buckle housing 21. In another embodiment, the cam structure 311 includes a driving surface 312 and an abutting surface 313 arranged opposite to each other. The maximum distance from the driving surface 312 to the axis of the first rotating shaft 31 is greater than the maximum distance from the abutting surface 313 to the axis of the first rotating shaft 31; the cam groove 224 includes a driving part 225 protruding into the groove space. When the driving surface 312 abuts against the driving part 225, the installation part 221 moves radially relative to the buckle housing 21 along the first rotating shaft 31, so that the insertion part 222 disengages from the insertion groove 102.

[0095] In this embodiment, both the driving surface 312 and the abutting surface 313 of the cam structure 311 are configured as arc surfaces. In this way, the arc-shaped outer wall surface of the cam structure 311 abuts against the cam groove 224, so that the rotation of the cam structure 311 is smoother and can stably drive the installation part 221 during rotation.

[0096] Please refer to Figure 2 、 Figure 6 and Figure 7 , the cam structure 311 has opposite driving surface 312 and abutting surface 313, and the maximum distance L1 from the driving surface 312 to the axis of the first rotating shaft 31 is greater than the maximum distance L2 from the abutting surface 313 to the axis of the first rotating shaft 31.

[0097] Furthermore, the cam groove 224 is formed with a driving part 225 protruding into the groove space. The driving part 225 is located on the side of the cam groove 224 away from the insertion part 222. Relative to the radial direction of the first rotating shaft 31, the driving part 225 and the insertion part 222 are respectively located on both sides of the first rotating shaft 31. Exemplarily, please refer to Figure 7, when the first rotating shaft 31 is in the initial state, the abutting surface 313 of the cam structure 311 abuts against the driving part 225. The initial state of the first rotating shaft 31 is usually the state of the first rotating shaft 31 when the main body 40 of the host is stacked on the bracket body 10. The rotating connection assembly 30 and the locking component 20 can be relatively parallel, and the rotation angle of the first rotating shaft 31 is 0°. It can be understood that by reasonably pre-fixing the position of the mounting part 221 in the locking housing 21, it can be ensured that when the rotation angle of the first rotating shaft 31 is 0°, the abutting surface 313 of the cam structure 311 abuts against the driving part 225, the first elastic member 220 is in the initial state, and the inserting part 222 extends out of the locking housing 21. At the same time, the length of the driving part 225 protruding into the cam groove 224 is positively correlated with the length of the inserting part 222.

[0098] Please refer to Figure 6 , during the process that the user needs to remove the main body 40 of the host from the bracket body 10 to rotate the main body 40 of the host, when the first rotating shaft 31 rotates a preset angle along with the main body 40 of the host, for example: when it rotates 180°, when the cam structure 311 rotates to the driving surface 312 abutting against the driving part 225, the mounting part 221 moves relative to the locking housing 21 along the radial direction of the first rotating shaft 31, and the inserting part 222 retracts into the locking housing 21 and disengages from the inserting groove 102. In this way, when the driving surface 312 abuts against the driving part 225, since the driving surface 312 is far from the axis of the first rotating shaft 31, at this time, the driving surface 312 of the cam structure 311 can drive the driving part 225 of the cam groove 224 to move away from the axis of the first rotating shaft 31. Therefore, the mounting part 221 can drive the inserting part 222 to disengage from the inserting groove 102 of the bracket body 10.

[0099] When the user continues to rotate the main body 40 of the host, the first rotating shaft 31 rotates along with the main body 40 of the host, and the driving surface 312 of the cam structure 311 is separated from the driving part 225 of the cam groove 224, and switches to the state where the abutting surface 313 as shown in Figure 7 abuts against the driving part 225 of the cam groove 224. Since the abutting surface 313 is close to the axis of the first rotating shaft 31, the distance between the driving part 225 and the axis of the first rotating shaft 31 becomes smaller, so that the mounting part 221 can be displaced. In this way, under the driving of the restoring elastic force of the first elastic member 220, the mounting part 221 moves in the direction close to the axis of the first rotating shaft 31. Therefore, the inserting part 222 can extend out of the locking housing 21 again, and under the action of the elastic force of the first elastic member 220, it maintains the state of extending out of the locking housing 21, so that the locking component 20 can be installed in the mounting groove 101 of the bracket body 10 by pressing the inserting part 222 back into the locking housing 21 through the groove wall of the mounting groove 101 at any time.

[0100] Optionally, when the insertion part 222 extends out of the latch housing 21, there is a gap between the driving surface 312 and the groove wall of the cam groove 224.

[0101] When the main body 40 drives the rotating connection assembly 30 to rotate to form a preset angle with the latch assembly 20, the first rotating shaft 31 causes the insertion part 222 to retract into the latch housing 21 through the cam structure 311, thereby completing the disassembly of the main body 40 of the host and the bracket body 10. In other cases, the insertion part 222 of the elastic insert 22 can be kept in the state of extending out of the latch housing 21. On the one hand, when the latch assembly 20 is installed in the installation groove 101, the insertion part 222 can stably form an insertion relationship with the insertion part 222, so that the latch assembly 20 is in a locked state. On the other hand, when the latch assembly 20 is not installed in the installation groove 101, the insertion part 222 extending out of the latch assembly 20 can also be pressed back into the latch housing 21 at any time during the installation process, thereby completing the installation of the latch assembly 20.

[0102] Therefore, please refer to Figure 2 、 Figure 6 and Figure 7 , the notch shape of the cam groove 224 needs to be designed with a margin to ensure that in most cases, there is a gap between the cam groove 224 and the driving surface 312 of the cam structure 311. Even if the cam structure 311 rotates, the above-mentioned gap can ensure that the cam groove 224 does not contact the driving surface 312 of the cam structure 311, so that the insertion part 222 of the elastic insert 22 can be kept in the state of extending out of the latch housing 21, thereby improving the connection stability between the insertion part 222 and the insertion slot 102. Only when the first rotating shaft 31 rotates a preset angle, for example, 180°, the driving surface 312 of the cam structure 311 rotates to the position where it abuts against the driving part 225, causing the insertion part 222 to retract into the latch housing 21.

[0103] In order to improve the connection stability between the latch assembly 20 and the installation groove 101 of the bracket body 10 to ensure that the latch assembly 20 can be stably connected to the bracket body 10 when in the locked state, in some other embodiments, the latch assembly 20 includes two elastic inserts 22 arranged along the axial direction of the first rotating shaft 31, and the insertion parts 222 on the two elastic inserts 22 are arranged back to back along the radial direction of the first rotating shaft 31; the first rotating shaft 31 is provided with two cam structures 311 arranged along the axial direction of the first rotating shaft 31, and the two cam structures 311 are respectively matched with the cam grooves 224 of the two elastic inserts 22; along the radial direction of the first rotating shaft 31, the two driving surfaces 312 of the two cam structures 311 are respectively located on the opposite sides of the first rotating shaft 31.

[0104] In this embodiment, by providing two elastic plug connectors 22 and two cam structures 311, the two cam structures 311 respectively drive the two plug portions 222 to be plugged into the two plug slots 102 of the bracket body 10. The latch assembly 20 and the bracket body 10 have two connection positions, which is beneficial to improving the connection stability between the latch assembly 20 and the bracket body.

[0105] Specifically, the two elastic plug connectors 22 are arranged along the axial direction of the first rotating shaft 31, and the two cam structures 311 are also arranged along the axial direction of the first rotating shaft 31, so that the two cam structures 311 can respectively drive the two elastic plug connectors 22.

[0106] The two elastic plug connectors 22 have the same structure, and the plug portions 222 of the two elastic plug connectors 22 are arranged back to back, so that both opposite sides of the latch housing 21 can protrude the plug portions 222, and both sides of the latch assembly 20 can establish a connection relationship with the plug slots 102 in the mounting groove 101. Similarly, the cam grooves 224 and the plug portions 222 on the two elastic plug connectors 22 also have the same structure.

[0107] The two cam structures 311 also have the same structure. Along the radial direction of the first rotating shaft 31, the two driving surfaces 312 of the two cam structures 311 are respectively located on the opposite sides of the first rotating shaft 31. At the same time, the two abutting surfaces 313 of the two cam structures 311 are also respectively located on the two opposite sides of the axis of the first rotating shaft 31. Since the two plug portions 222 are also arranged back to back, the two cam structures 311 can simultaneously drive the two elastic plug connectors 22 and drive the plug portions 222 to be disengaged from the plug slots 102 of the bracket body 10, ensuring the synchronism of the movement of the plug portions 222 on both sides of the latch housing 21.

[0108] In another embodiment, at least two plug portions 222 are formed at the end of the mounting portion 221, and at least two first sockets 212 are provided on the latch housing 21 to respectively correspond to the at least two plug portions 222.

[0109] Specifically, each mounting portion 221 may include two plug portions 222, and the two plug portions 222 are arranged at intervals. Two first sockets 212 may be respectively provided at the positions corresponding to the plug portions 222 on one side surface of the latch housing 21 to allow the two plug portions 222 to protrude. Since there are two mounting portions 221, two first sockets 212 are also formed on the other side surface of the latch assembly 20 to allow the two plug portions 222 of the other mounting portion 221 to pass through.

[0110] In order to further improve the connection stability between the buckle assembly 20 and the bracket body 10 and the integration degree of the buckle assembly 20, in another embodiment, the buckle assembly 20 further includes: a buckle component 23, which is movably arranged in the buckle housing 21. When the buckle component 23 is subjected to a pressure towards the inside of the buckle housing 21, the buckle component 23 can retract into the buckle housing 21. When the buckle housing 21 is placed in the installation groove 101 and the buckle component 23 corresponds to the card slot 103 arranged on the installation groove 101, the buckle component 23 can be reset to insert into the card slot 103.

[0111] Please refer to Figure 2 and Figure 10 As shown in FIG. and FIG., the buckle assembly 20 further includes a buckle component 23. A card slot 103 is arranged at a corresponding position on the groove wall of the installation groove 101. The buckle component 23 is movably arranged in the buckle assembly 20. Similar to the elastic plug 22, when the buckle component 23 is subjected to a pressure towards the inside of the buckle assembly 20, it can also retract into the buckle assembly 20. When the buckle component 23 is aligned with the card slot 103, the buckle component 23 can be inserted into the card slot 103.

[0112] For the assembly process of installing the buckle assembly 20 on the bracket body 10, the buckle component 23 can be inserted into the card slot 103 to realize the pre-positioning of the buckle housing 21 in the installation groove 101. After the buckle component 23 extends into the card slot 103, the locking state of the buckle assembly 20 can be made more stable and reliable.

[0113] When it is necessary to disassemble the buckle assembly 20 from the installation groove 101, the user can drive the first rotating shaft 31 to rotate by rotating the main body 40 of the host, so that the cam structure 311 on the first rotating shaft 31 drives the installation part 221 to move, so that the insertion part 222 is disengaged from the insertion slot 102. After the insertion part 222 is disengaged from the insertion slot 102, the buckle assembly 20 as a whole is in a detachable state. At this time, the buckle component 23 can provide a certain insertion force to keep the buckle housing 21 in the installation groove 101, so as to prevent the main body 40 of the host from being lost due to the loss of the locking relationship between the insertion part 222 and the insertion slot 102 when the user does not pull out the main body 40 of the host from the bracket body 10.

[0114] Optionally, a stopper 217 extending along the axial direction of the first rotating shaft 31 is provided inside the buckle housing 21. A second receiving groove 228 is formed between at least two plugging portions 222 of the mounting portion 221. The stopper 217 extends into the second receiving groove 228. The buckle assembly 23 includes: a buckle 231, and guiding inclined surfaces are respectively formed on two sides of the buckle 231 close to and away from the rotating connection assembly 30; a second elastic member 232, one end of the second elastic member 232 is connected to the buckle 231, and the other end of the second elastic member 232 abuts against the stopper 217; a second socket 213 is provided on the buckle housing 21 corresponding to the buckle 231, and the buckle 231 can be inserted into the card slot 103 through the second socket 213.

[0115] Please refer to Figure 2 , Figure 8 and Figure 10 , a second receiving groove 228 is formed between two plugging portions 222 at the end of the mounting portion 221. The buckle assembly 23 can be arranged in the second receiving groove 228, so as to reasonably utilize the space between the two plugging portions 222 of the mounting portion 221, making the spatial layout of the components in the buckle assembly 20 more compact.

[0116] A stopper 217 extending along the axial direction of the first rotating shaft 31 is formed on the buckle housing 21. The stopper 217 extends into the second receiving groove 228 along the axial direction of the first rotating shaft 31, so that the buckle assembly 23 can abut against the stopper 217, and the stopper 217 provides an abutting surface for the deformation of the buckle assembly 23.

[0117] The buckle assembly 23 includes a buckle 231 and a second elastic member 232. One end of the second elastic member 232 abuts against the stopper 217, and the other end is connected to the buckle 231. A second socket 213 is formed on the buckle housing 21 at a position corresponding to the buckle 231.

[0118] In this way, by abutting the second elastic member 232 against the stopper 217 and connecting the buckle 231, the buckle 231 can be made to move relative to the second socket 213 provided on the buckle housing 21. When installing or disassembling the buckle assembly 20 into or from the installation groove 101, under the extrusion of the groove wall of the installation groove 101, the buckle 231 can contract into the buckle housing 21, so that the buckle housing 21 can be installed in the installation groove 101 or disassembled from the installation groove 101. When the buckle housing 21 is located in the installation groove 101, the buckle 231 is engaged in the card slot 103 of the bracket body 10 under the elastic action of the second elastic member 232, realizing the pre-positioning function of the buckle assembly 20.

[0119] It should be noted that the buckle 231 has guiding inclined surfaces on both surfaces close to and away from the rotation connection assembly 30. That is, when the buckle 231 is removed from and inserted into the installation groove 101, the guiding inclined surfaces can reduce the frictional force between the buckle 231 and the groove wall of the installation groove 101, thereby making it easier for the buckle 231 to retract into the lock housing 21.

[0120] Exemplarily, the second elastic member 232 can be a spring or a spring sheet.

[0121] In order to make the lock assembly 20 have a more aesthetic appearance surface, after the lock assembly 20 is detached from the bracket body 10 along with the main body 40 of the host, no obvious welding points can be seen on the appearance of the lock assembly 20. In another embodiment, the lock housing 21 can include a first housing 214 and a second housing 215. The first housing 214 is provided with a first through opening 216 and a first opening 218 facing away from the rotation connection assembly 30; the second housing 215 closes the first opening 218, and a connecting column 219 is provided on the side of the second housing 215 facing the first housing 214. The connecting column 219 extends along the axial direction of the first rotating shaft 31 and is arranged to avoid the installation portion 221. The connecting column 219 is connected to a welding member provided in the first through opening 216 to connect the second housing 215 to the first housing 214.

[0122] In this embodiment, the lock housing 21 can include a first housing 214 and a second housing 215. The first housing 214 has a first opening 218, so that during the installation process, the first rotating shaft 31, the elastic plug-in member 22 and the buckle assembly 23 are installed into the interior of the first housing 214 through the first opening 218.

[0123] Two first through openings 216 are further provided on the first housing 214. The two first through openings 216 can be respectively located on both sides of the through hole of the first housing 214 for passing through the first rotating shaft 31. The first through opening 216 is used to accommodate a welding member, and the welding member can be a welding bead.

[0124] The second housing 215 is used to close the first opening 218. A connecting column 219 is provided on the second housing 215. The connecting column 219 extends along the axial direction of the first rotating shaft 31 and can abut against the first through opening 216 on the first housing 214. In this way, the connecting column 219 can be welded to the first housing 214 through the welding bead accommodated in the first through opening 216, so that the second housing 215 and the first housing 214 are welded. Since the surface of the first housing 214 where the first through opening 216 is provided faces the rotation connection assembly 30, even if welding points are formed on the surface of the first housing 214 close to the rotation connection assembly 30, the welding points will be invisible to the user through the shielding of the rotation connection assembly 30, thereby improving the overall aesthetic degree of the lock assembly 20.

[0125] Considering that the movable mounting portion 221 is provided in the buckle housing 21, in order to avoid interfering with the movement of the mounting portion 221, the connecting column 219 needs to be arranged to avoid the mounting portion 221, and this avoidance can be achieved by providing a clearance area on the mounting portion 221. Combining the foregoing embodiments, the second receiving groove 228 provided on the mounting portion 221 can be used to form an avoidance with the connecting column 219, that is, the connecting column 219 can extend into the second receiving groove 228 and be located between the groove wall of the second receiving groove 228 and the stopper 217. In this way, the connecting column 219 will neither interfere with the movement of the mounting portion 221 nor interfere with the movement of the buckle assembly 23, and can also firmly connect the first housing 214 and the second housing 215.

[0126] In another embodiment, the rotation connection assembly 30 further includes: a mounting seat 32 and a second rotating shaft 329. The second rotating shaft 329 is provided on the mounting seat 32, and the axis of the second rotating shaft 329 is perpendicular to the axis of the first rotating shaft 31. The second rotating shaft 329 is connected to the main body 40 of the host, so that the main body 40 of the host can be flipped relative to the bracket body 10; the first rotating shaft 31 and the second rotating shaft 329 are arranged at intervals, and the first rotating shaft 31 is connected to the mounting seat 32 to be connected to the main body 40 of the host through the mounting seat 32 and rotate with the main body 40 of the host.

[0127] Please refer to Figure 11 and Figure 12 In the rotation connection assembly 30, there are also a mounting seat 32 and a second rotating shaft 329. The second rotating shaft 329 is provided on the mounting seat 32, and the second rotating shaft 329 is rotatably connected to the main body 40 of the host. For example, the second rotating shaft 329 is rotatably connected to the connecting member 36, and the connecting member 36 is fixed to the main body 40 of the host. The second rotating shaft 329 is used to make the main body 40 of the host flip relative to the bracket body 10. The first rotating shaft 31 is provided on the mounting seat 32 and is arranged at intervals with the second rotating shaft 329. The axis of the first rotating shaft 31 is perpendicular to the axis of the second rotating shaft 329. One end of the first rotating shaft 31 is connected to the mounting seat 32 to be connected to the main body 40 of the host through the mounting seat 32 and the second rotating shaft 329 and rotate synchronously with the main body 40 of the host. The other end of the first rotating shaft 31 extends in the direction of the buckle assembly 20, and a cam structure 311 is provided at the end extending into the buckle assembly 20.

[0128] Thus, by providing the first rotating shaft 31 and the second rotating shaft 329 with perpendicular axes, when the main body 40 of the host is mounted to the bracket body 10, the main body 40 of the host can rotate around its own axis through the first rotating shaft 31, and at the same time, the main body 40 of the host can be turned relative to the bracket body 10 through the second rotating shaft 329, so as to meet various usage requirements of users. At the same time, by the rotation of the first rotating shaft 31, the elastic plug-in member 22 is driven to disengage from the plug-in groove 102 on the bracket body 10, so as to make the locking component 20 detachable from the bracket body 10.

[0129] Optionally, a first gear portion 24 is formed on the surface of the locking housing 21 facing the rotating connection assembly 30. The first gear portion 24 includes a first gear protrusion 241 and a first gear recess 242. A second gear portion 34 is formed on the side of the mounting seat 32 facing away from the third elastic member 33. The second gear portion 34 also includes a second gear protrusion 341 and a second gear recess 342. During the process that the first rotating shaft 31 drives the elastic plug-in member 2322 to move out of the plug-in groove 102, the first gear protrusion 241 switches from abutting against the second gear recess 342 to abutting against the second gear protrusion 341; the second gear protrusion 341 switches from abutting against the first gear recess 242 to abutting against the first gear protrusion 241. A third elastic member 33 is disposed in the mounting seat 32. The third elastic member 33 is sleeved on the first rotating shaft 31. During the process that the first rotating shaft 31 drives the elastic plug-in member 22 to move out of the plug-in groove 102, the third elastic member 33 deforms along the axial direction of the first rotating shaft 31, and the elastic force generated by the deformation of the third elastic member 33 is used to keep the first gear portion 24 and the second gear portion 34 in a pressed state.

[0130] Please refer to Figure 7 and Figure 9 , a first gear portion 24 is provided on the surface of the locking housing 21 facing the rotating connection assembly 30, and a second gear portion 34 is provided on the side of the mounting seat 32 facing the locking housing 21. The second gear portion 34 is used to cooperate with the first gear portion 24 when the cam structure 311 drives the plug-in portion 222 to move out of the plug-in groove 102.

[0131] By providing the first gear portion 24 and the second gear portion 34, when the user rotates the main body 40 of the host to disassemble the main body 40 of the host from the bracket body 10, the cooperation distance between the first gear portion 24 and the second gear portion 34 increases, so that the third elastic member 33 is compressed. The user can feel the damping sensation, which is convenient for the user to know the disassembly state and has a better feel. In addition, by providing the first gear portion 24 and the second gear portion 34, the friction force between the mounting seat 32 and the locking component 20 can be increased, and the damping sensation is further enhanced.

[0132] Specifically, the first shift portion 24 includes a first shift convex portion 241 and a first shift concave portion 242, which are connected by an inclined surface. The second shift portion 34 includes a second shift convex portion 341 and a second shift concave portion 342, which are connected by an inclined surface.

[0133] When the host body 40 is installed on the bracket body 10 and is in a stacked state, the first gear position concave portion 242 cooperates with the second gear position convex portion 341, and the first gear position convex portion 241 cooperates with the second gear position concave portion 342. When the host body 40 is rotated and the rotating connection assembly 30 rotates synchronously with the host body 40, since the locking assembly 20 is stuck in the installation groove 101, the second gear portion 34 starts to rotate and climb relative to the first gear portion 24. When the host body 40 rotates a preset angle, for example: 180°, the second gear position convex portion 341 abuts against the first gear position convex portion 241, and the second gear position concave portion 342 is opposite to the first gear position concave portion 242.

[0134] Since the distance between the first gear portion 24 and the second gear portion 34 increases compared to the state when the host body 40 is not rotated, the third elastic member 33 in the mounting seat 32 and sleeved on the first rotating shaft 31 is compressed, and the elastic force generated by the compression of the third elastic member 33 keeps the first gear portion 24 and the second gear portion 34 in a pressed state. Therefore, during the relative movement of the first gear portion 24 and the second gear portion 34, the two remain in a pressed state and generate sliding friction, so that the user can feel the damping force and the sense of jamming when rotating the host body 40, so that the user can understand that the host body 40 has been rotated to a state where it can be disassembled or installed.

[0135] Optionally, the third elastic member 33 is a spring with a rectangular cross-section.

[0136] The rectangular cross-section spring is a spiral spring. Under the same space conditions, the compression spring stiffness of the rectangular cross-section spring is greater. Therefore, the third elastic member 33 is a rectangular cross-section spring. Under the condition of generating the same elastic force, the outer diameter of the third elastic member 33 can be further reduced. In this way, the diameter of the first rotating shaft 31 can also be further reduced. At the same time, the third elastic member 33 made of a rectangular cross-section spring can further reduce the space requirement, making the first frame 322 and the second frame 324 in the above embodiment more miniaturized.

[0137] In some embodiments, the mounting seat 32 includes: a seat body 321, on which a first through hole is provided, and the first rotating shaft 31 passes through the first through hole and extends into the latch assembly 20; two first frames 322, each first frame 322 being connected to the seat body 321; a second frame 324, the first rotating shaft 31 being connected to the second frame 324, the second frame 324 covering the two first frames 322 and being in limit cooperation with the two first frames 322 respectively; one end of a third elastic member 33 abuts against the second frame 324, the other end of the third elastic member 33 abuts against the seat body 321, and the third elastic member 33 is placed in the space enclosed by the second frame 324 and the two first frames 322.

[0138] In this embodiment, the mounting seat 32 includes a seat body 321, a first frame 322 and a second frame 324. The seat body 321 is used to provide the first through hole for the first rotating shaft 31. A third elastic member 33 is arranged in the space enclosed by the first frame 322 and the second frame 324 and the seat body 321. The third elastic member 33 is sleeved on the first rotating shaft 31. One end of the third elastic member 33 abuts against the second frame 324, and the other end abuts against the seat body 321.

[0139] In the related art, a cover body for protecting the third elastic member is provided on the seat body, and a steel sheet is further provided on the outside of the cover body, and the whole cover body covers the outside of the third elastic member. Since the seat body needs to support the cover body, the width of the seat body needs to be greater than the width of the cover body, so that the seat body needs to occupy more internal space of the rotational connection assembly. However, for the mounting seat 32 provided in the embodiment of the present application, as Figure 11 shown, two first frames 322 are formed at two edges of the seat body 321, and the two first frames 322 extend in a direction away from the seat body 321. The second frame 324 covers the two first frames 322, so that the second frame 324 and the first frame 322 are buckled to form a cover body for accommodating the first rotating shaft 31 and the third elastic member 33, reducing the space occupation, and enabling the rotational connection assembly 30 to be further miniaturized. At the same time, the space saved by canceling the cover body can also be used to strengthen the strength of the first frame 322, thereby improving the structural strength of the rotational connection assembly 30.

[0140] Further, the first frame 322 is arranged on the seat body 321, and is in limit cooperation with the second frame 324. The first rotating shaft 31 is connected to the second frame 324. Therefore, a connection relationship is formed between the first rotating shaft 31 and the seat body 321. When the seat body 321 rotates with the main body 40 of the host, through the cooperation relationship among the seat body 321, the first frame 322 and the second frame 324, the first rotating shaft 31 can rotate synchronously with the main body 40 of the host.

[0141] Optionally, a limiting port 323 is provided on one side of each first frame body 322 facing away from the locking component 20; the second frame body 324 includes two outwardly protruding portions 325 arranged back to back, and each outwardly protruding portion 325 is clamped in the limiting port 323, and the outwardly protruding portion 325 does not protrude from the outer surface of the first frame body 322.

[0142] Please refer to Figure 11 , a limiting port 323 is provided on each of the two first frame bodies 322 of the two first frame bodies 322, and the second frame body 324 includes two outwardly protruding portions 325 arranged back to back. When the outwardly protruding portion 325 is clamped in the second frame body 324, a limiting fit is formed between the first frame body 322 and the second frame body 324. At the same time, the second frame body 324 is further provided with a limiting hole 327, and the limiting hole 327 is used for limiting connection with the first rotating shaft 31, so as to realize the limiting fit relationship among the seat body 321, the first frame body 322, the second frame body 324 and the first rotating shaft 31, and the first rotating shaft 31 can rotate synchronously with the main body 40 of the host. The outwardly protruding portion 325 does not protrude from the outer surface of the first frame body 322, which can further improve the structural compactness of the internal components of the rotating connection assembly 30.

[0143] In another embodiment, the mounting seat 32 further includes a boss 326 provided on the seat body 321. The two bosses 326 are respectively located on both sides of the first through hole. The boss 326 is provided with a second through hole, and the second rotating shaft 329 is connected to the second through hole through a shaft sleeve 330 and at least partially exposed outside the boss 326.

[0144] Please refer to Figure 11 , a boss 326 is provided on one side of the seat body 321 facing away from the locking component 20. The boss 326 is provided with a through second through hole, and the second rotating shaft 329 is passed through the second through hole through a shaft sleeve 330. In this way, by arranging the locking component 20, the first rotating shaft 31 and the second rotating shaft 329 on the side of the seat body 321 facing the locking component 20 and the side facing away from the locking component 20 respectively, the structure of the intelligent host 1 is made compact.

[0145] It can be understood that, in order to stably connect the main body 40 of the host with the second rotating shaft 329, the second rotating shaft 329 can be provided with two. Similarly, the boss 326 is also provided with two. The two bosses 326 are respectively arranged on two opposite sides of the first through hole, and the two bosses 326 are both provided with second through holes, so as to respectively pass the two second rotating shafts 329 through the two second through holes and connect them to both ends of the main body 40 of the host, thereby improving the connection stability between the main body 40 of the host and the second rotating shaft 329 to ensure the stability of the relative flipping movement of the main body 40 of the host with respect to the bracket body 10.

[0146] Optionally, the rotating connection assembly 30 further includes: a connecting member 36 for connecting the main body 40 of the host. One end of the second rotating shaft 329 exposed outside the boss 326 is inserted through the connecting member 36, and the connecting member 36 can rotate relative to the second rotating shaft 329 driven by the main body 40 of the host.

[0147] Specifically, the second rotating shaft 329 is fixed in the boss 326 through a bushing 330. One end of the second rotating shaft 329 extends out of the boss 326 and is inserted into the connecting member 36 to be movably connected to the connecting member 36. The connecting member 36 is configured as a bent structure, and the bent part is connected to the main body 40 of the host, so that the connecting member 36 can rotate around the second rotating shaft 329 driven by the main body 40 of the host, thereby realizing the flipping of the main body 40 of the host relative to the bracket body 10.

[0148] In order to protect the components provided in the rotating connection assembly 30, in another embodiment, the rotating connection assembly 30 further includes: a protective cover 35 disposed on the mounting seat 32 and covering the mounting seat 32; along the width direction of the mounting groove 101, the width of the protective cover 35 is D1, and D1 satisfies 5.8 mm ≤ D1 ≤ 6.2 mm.

[0149] The rotating connection assembly 30 further includes a protective cover 35. The protective cover 35 is disposed outside the first rotating shaft 31, the second rotating shaft 329 and the mounting seat 32 and covers the mounting seat 32, so as to protect the first rotating shaft 31 and the second rotating shaft 329.

[0150] It should be noted that, as described above, the mounting seat 32 and the third elastic member 33 in the rotating connection assembly 30 provided in the present application are both smaller in size than the related art. Please refer to Figure 14 and Figure 15 so that the mounting seat 32, the third elastic member 33 and the first rotating shaft 31 are all further miniaturized.

[0151] Therefore, the size of the protective cover 35 can also be further miniaturized, so that the width D1 of the protective cover 35 satisfies 5.8 mm ≤ D1 ≤ 6.2 mm.

[0152] Specifically, the width of the protective cover 35 can be 5.8 mm, 6 mm or 6.2 mm.

[0153] In order to further miniaturize the intelligent host 1 as a whole, in another embodiment, along the width direction of the mounting groove 101, the width of the lock housing 21 is D2, and D2 satisfies 4.8 mm ≤ D2 ≤ 5.2 mm.

[0154] Please refer to Figure 15, since in the embodiment of the present application, the first elastic member 220 is used as the reset driving member of the elastic plug 22, the structure is simple and the occupied space is small, so that the size of the latch assembly 20 is further reduced. Along the width direction of the installation groove 101, the width of the latch housing 21 is D2, and D2 satisfies 4.8 mm ≤ D2 ≤ 5.2 mm.

[0155] Specifically, the width of the latch housing 21 can be 4.8 mm, 5 mm or 5.2 mm.

[0156] Please refer to Figure 9 , Figure 10 and Figure 13 , in order to further improve the assembly convenience of the latch assembly 20 and the installation groove 101, in another embodiment, a guiding rib 104 is provided on one of the installation groove 101 and the latch housing 21, and a guiding groove 25 is provided on the other of the installation groove 101 and the latch housing 21, and the guiding groove 25 is cooperatively connected with the guiding rib 104.

[0157] Providing the guiding rib 104 on one of the latch housing 21 and the installation groove 101 and providing the guiding groove 25 on the other can provide guidance for the process of inserting the latch housing 21 into the installation groove 101, so that the latch assembly 20 can be inserted into the installation groove 101 from the correct installation angle. In this way, it is also more conducive to the plug and the plugging groove 102 being correctly positioned.

[0158] Optionally, please refer to Figure 10 , the installation groove 101 is formed with a limiting boss 105 extending into the groove, and the limiting boss 105 is used to support the latch assembly 20.

[0159] It can be understood that the connection between the latch assembly 20 and the bracket body 10 is realized by the clamping of the elastic plug 22 and the plugging groove 102. In order to reduce the requirement for the structural strength of the elastic plug 22, a limiting boss 105 can also be provided in the installation groove 101, and the limiting boss 105 can be used to support the latch assembly 20, thereby reducing the acting force generated by the gravity of the latch assembly 20 on the elastic plug 22 and improving the service life of the latch assembly 20.

[0160] Please refer to Figure 16 , the second aspect of the embodiment of the present application discloses a wearable device 2, including an intelligent host 1 and a wearable component 50. The intelligent host 1 is the intelligent host 1 in any of the above embodiments, and the wearable component 50 is connected to the bracket body 10 of the intelligent host 1.

[0161] It can be understood that the wearable device 2 adopting the intelligent host 1 of the above embodiment has all the technical effects of the intelligent host 1 of the above embodiment, which will not be elaborated here.

[0162] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
