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] Wearable electronic products (such as smart watches, smart bracelets, etc.) are becoming increasingly popular and also integrate functions such as calling and shooting to meet various usage needs of users.

[0003] In order to achieve detachable connection of the main body of the host in the wearable device relative to the main body of the bracket, an elastic key component is usually provided on the main body of the host. The user can press the key component to make the detachable connection between the main body of the host and the main body of the bracket.

[0004] However, the key component is very easy to be accidentally touched during the user's wearing process. When the user does not need to disassemble the main body of the host, accidentally touching the key component on the main body of the host easily causes the main body of the host to disengage from the main body of the bracket, resulting in the loss of the main body of the host, thus greatly affecting the user experience.

[0060] Such as Figure 1The following is a schematic structural diagram of the intelligent host 1 provided by an embodiment of the present application. It includes a host body 40, a bracket body 10, a rotating connection component 30, and a locking component 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 component 20 includes a locking housing 21 and a plug-in member 22 movably arranged in the locking housing 21. A cam groove 221 is provided on the plug-in member 22. The rotating connection component 30 is connected to the host body 40. The rotating connection component 30 includes a first rotating shaft 31 extending into the locking component 20. The rotating connection component 30 is rotatably connected to the locking component 20 through the first rotating shaft 31. One end of the first rotating shaft 31 extending into the locking component 20 is formed with a cam structure 32 that cooperates with the cam groove 221. Wherein, the cam structure 32 can insert at least part of the plug-in member 22 into the plug-in groove 102 through cooperation with the cam groove 221 when the first rotating shaft 31 rotates, so that the locking component 20 is installed on the bracket body 10. The cam structure 32 can also make the plug-in member 22 disengage from the plug-in groove 102 through cooperation with the cam groove 221 when the first rotating shaft 31 rotates, so that the locking component 20 is detachable relative to the bracket body 10.

[0061] The intelligent host 1 provided by an embodiment of the present application includes a host body 40, a bracket body 10, a rotating connection component 30, and a locking component 20. The rotating connection component 30 and the locking component 20 are used to establish a detachable connection relationship between the host body 40 and the bracket body 10. Among them, the rotating connection component 30 is respectively connected to the host body 40 and the locking component 20. The locking component 20 is detachably arranged in the installation groove 101 of the bracket body 10, so that the host body 40 is detachable relative to the bracket body 10.

[0062] Please refer to Figure 1 , an installation groove 101 for accommodating the locking component 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. The locking component 20 includes a locking housing 21 and a plug-in member 22. The plug-in member 22 can move in the locking housing 21. When the plug-in member 22 is subjected to a force towards the inside of the locking housing 21, the 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 plug-in member 22 corresponds to the plug-in groove 102, the plug-in member 22 can be reset to insert into the plug-in groove 102, so as to connect the locking component 20 with the bracket body 10, and further the host body 40 can be stably installed on the bracket body 10.

[0063] 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. The first rotating shaft 31 is rotatably connected to the locking assembly 20. A cam mechanism is formed at one end of the first rotating shaft 31 extending into the locking assembly 20. A cam groove 221 is formed on the plug-in member 22 and penetrates axially along the first rotating shaft 31. The cam mechanism can cooperate with the cam groove 221, so that the plug-in member 22 can reciprocate radially along the first rotating shaft 31 in the locking housing 21 under the drive of the cam structure 32.

[0064] Specifically, the cam structure 32 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 32 drives the plug-in member 22 to move. The cam structure 32 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 32.

[0065] 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 it is necessary 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, and the main body 40 of the host drives the first rotating shaft 31 to rotate so that the cam structure 32 moves in the cam groove 221. The abutment of the cam structure 32 and the cam groove 221 drives the plug-in member 22 to move radially inward of the locking housing 21 along the first rotating shaft 31. When the main body 40 of the host drives the first rotating shaft 31 to rotate to a preset angle, the plug-in member 22 retracts into the locking housing 21 and can be disengaged from the plug-in groove 102, and the main body 40 of the host can be disassembled from the bracket body 10.

[0066] When it is necessary to install the main body 40 of the host on the bracket body 10 again, the locking assembly 20 can be placed into the installation groove 101 again (it is necessary to keep the plug-in member 22 retracted into the locking housing 21), and then rotate the main body 40 of the host so that the first rotating shaft 31 rotates, so that the cam structure 32 moves in the cam groove 221. The abutment of the cam structure 32 and the cam groove 221 drives the plug-in member 22 to move radially outward of the locking housing 21 along the first rotating shaft 31, and the plug-in member 22 can be at least partially inserted into the plug-in groove 102, so that the main body 40 of the host is stably arranged on the bracket body 10.

[0067] Optionally, considering that a fitting gap may need to be reserved between the plug-in groove 102 and the plug-in member 22, the value of the preset angle is determined between 170° and 190°.

[0068] Specifically, the preset angles may be 170°, 172°, 174°, 176°, 178°, 180°, 182°, 184°, 186°, 188°, 190°, etc.

[0069] In this way, the intelligent host 1 provided by the embodiment of the present application is connected to the rotating connection component 30 through the host body 40, and the rotating connection component 30 is movably connected to the buckle component 20. When the host body 40 rotates, it drives the rotating connection component 30 to rotate relative to the buckle component 20, so that the cam structure 32 on the first rotating shaft 31 in the rotating connection component 30 can drive the plug-in member 22 in the buckle component 20 to move, so as to lock the buckle component 20 to the bracket body 10 or be detachable from the bracket body 10. When the user needs to disassemble the host body 40 from the bracket body 10, the host body 40 needs to be rotated by a preset angle. Compared with the method of using magnetic attraction, elastic button clamping, etc. to realize the detachable connection between the host body 40 and the bracket body 10, it can effectively reduce misoperation. When the user does not have the intention to disassemble, the host body 40 will not be separated from the bracket body 10. Especially for users of young age, it can avoid the situation that the host body 40 is separated from the host body 40 due to misoperation, thereby improving the user experience.

[0070] In another embodiment, the plug-in member 22 forms a plug-in portion 222 at the end along the radial direction of the first rotating shaft 31 for plugging into the plug-in slot 102. Under the driving action of the cam structure 32, the plug-in member 22 drives the plug-in portion 222 to extend out or retract into the buckle housing 21, so that the plug-in portion 222 is inserted into or disengaged from the plug-in slot 102.

[0071] Please refer to Figure 2 , the plug-in member 22 forms a plug-in portion 222 at the end along the radial direction of the first rotating shaft 31, and the plug-in portion 222 can be configured as a pin-shaped structure extending along the radial direction of the first rotating shaft 31.

[0072] During the process that the first rotating shaft 31 rotates by a preset angle along with the host body 40, the cam structure 32 drives the plug-in member 22 to move towards the inside of the buckle housing 21 and drives the plug-in portion 222 to retract into the buckle housing 21. At this time, the plug-in portion 222 is disengaged from the plug-in slot 102, and the host body 40 can be separated from the bracket body 10. When the host body 40 needs to be reinstalled on the bracket body 10 again, the buckle component 20 with the plug-in portion 222 retracted into the buckle housing 21 can be placed into the installation slot 101, and then the host body 40 is rotated. When the first rotating shaft 31 continues to rotate along with the host body 40, the cam structure 32 instead drives the plug-in member 22 to move towards the outside of the buckle housing 21, and the plug-in portion 222 can extend out of the buckle housing 21, and the plug-in portion 222 is stably installed in the plug-in slot 102 again.

[0073] In this way, through the cooperative movement between the cam structure 32 on the first rotating shaft 31 and the cam groove 221 on the plug-in member 22, the plug-in portion 222 and the plug-in groove 102 can be locked or detached, improving the convenience of installing and disassembling the main body 40 of the host.

[0074] To ensure the driving of the plug-in member 22 by the cam structure 32, when the first rotating shaft 31 rotates a preset angle in the initial state, the plug-in portion 222 can be retracted into the lock housing 21 and separated from the plug-in groove 102, and when the first rotating shaft 31 continues to rotate, the plug-in portion 222 can be plugged into the plug-in groove 102 again. In another embodiment, please refer to Figure 4 , the cam structure 32 includes a first abutting portion 321 and a second abutting portion 322 arranged opposite to each other. The maximum distance from the first abutting portion 321 to the axis a-a of the first rotating shaft 31 is greater than the maximum distance from the second abutting portion 322 to the axis a-a of the first rotating shaft 31; the cam groove 221 includes a first abutting surface 2211 protruding into the groove. When the first abutting portion 321 abuts against the first abutting surface 2211, the plug-in member 22 moves towards the inside of the lock housing 21, and the plug-in portion 222 disengages from the plug-in groove 102. When the second abutting portion 322 abuts against the first abutting surface 2211, the plug-in member 22 moves towards the outside of the lock housing 21, and the plug-in portion 222 is inserted into the plug-in groove 102.

[0075] In this embodiment, both the first abutting portion 321 and the second abutting portion 322 of the cam structure 32 are configured as arc surfaces. In this way, the arc-shaped outer wall surface of the cam structure 32 abuts against the cam groove 221, making the rotation of the cam structure 32 smoother and enabling it to drive the plug-in member 22 stably when rotating.

[0076] Please refer to Figures 3 to 7 , the cam structure 32 has opposite first abutting portion 321 and second abutting portion 322. The maximum distance L1 from the first abutting portion 321 to the axis a-a of the first rotating shaft 31 is greater than the maximum distance L2 from the second abutting portion 322 to the axis a-a of the first rotating shaft 31. The first abutting portion 321 is used to drive the movement of the plug-in member 22.

[0077] Furthermore, the cam groove 221 forms a first abutting surface 2211. The first abutting surface 2211 is used to adjust the range of the preset angle for the plug-in portion 222 to retract into the lock housing 21. The first abutting surface 2211 is located on the side of the cam groove 221 away from the plug-in portion 222. Relative to the radial direction of the first rotating shaft 31, the first abutting surface 2211 and the plug-in portion 222 are respectively located on both sides of the first rotating shaft 31. Exemplarily, please refer to Figure 3 and Figure 6, when the first rotating shaft 31 is in the initial state, the second abutting portion 322 of the cam structure 32 abuts against the first abutting surface 2211. 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 assembly 20 can be relatively parallel, and the rotation angle of the first rotating shaft 31 can be 0°. It can be understood that by reasonably pre-fixing the position of the plug 22 in the lock housing 21, it can be ensured that when the rotation angle of the first rotating shaft 31 is 0°, the second abutting portion 322 of the cam structure 32 abuts against the first abutting surface 2211, and the plug portion 222 extends out of the lock housing 21.

[0078] Please refer to Figure 7 , when 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, the first rotating shaft 31 rotates a preset angle along with the main body 40 of the host. For example, when it is 180°, when the cam structure 32 rotates to the first abutting portion 321 abutting against the first abutting surface 2211, the plug 22 moves relative to the lock housing 21 along the radial direction of the first rotating shaft 31, the plug portion 222 retracts into the lock housing 21, and the inside of the plug portion 222 disengages from the plug slot 102. In this way, when the first abutting portion 321 abuts against the first abutting surface 2211, since the first abutting portion 321 is farther away from the axis of the first rotating shaft 31, at this time, the first abutting portion 321 of the cam structure 32 can drive the first abutting surface 2211 of the cam groove 221 to move toward the inside of the lock housing 21 away from the axis of the first rotating shaft 31. Therefore, the plug 22 can drive the plug portion 222 to disengage from the plug slot 102 of the bracket body 10.

[0079] When the user needs to fix the main body 40 of the host to the bracket body 10 again, the main body 40 of the host can be continuously rotated, the first rotating shaft 31 rotates along with the main body 40 of the host, the first abutting portion 321 of the cam structure 32 is separated from the first abutting surface 2211 of the cam groove 221, and switches to the state where the second abutting portion 322 abuts against the first abutting surface 2211 of the cam groove 221 as shown in Figure 3 and Figure 6 . At this time, the first abutting portion 321 faces away from the first abutting surface 2211. Since the second abutting portion 322 is closer to the axis of the first rotating shaft 31, the distance between the first abutting surface 2211 and the axis of the first rotating shaft 31 becomes smaller, causing the plug 22 to move toward the outside of the lock housing 21, and the plug 22 can be inserted into the plug slot 102 again, and the locking assembly 20 is installed in the installation slot 101 of the bracket body 10.

[0080] Optionally, the inner surface of the cam groove 221 further includes a second abutting surface 2212 connected to the first abutting surface 2211. The first abutting surface 2211 is farther from the insertion portion 222 than the second abutting surface 2212, and at least a part of the first abutting surface 2211 protrudes into the cam groove 221.

[0081] Please refer to Figure 4 , the first abutting surface 2211 includes two inwardly recessed segments that are recessed into the inner space of the cam groove 221. The two inwardly recessed segments are respectively located on both sides of the center line b-b of the plug-in member 22 in the width direction. The two inwardly recessed segments are the first inwardly recessed segment 2211a and the second inwardly recessed segment 2211c respectively. The first inwardly recessed segment 2211a and the second inwardly recessed segment 2211c can be symmetrically arranged relative to the center line b-b of the plug-in member 22. One end of the first inwardly recessed segment 2211a and the second inwardly recessed segment 2211c is respectively connected to the second abutting surface 2212, and the other end extends into the inner space of the cam groove 221 and intersects at the center line of the plug-in member 22 to form an inwardly protruding segment 2211b.

[0082] When it is necessary to disassemble the buckle assembly 20 from the installation groove 101, the cam structure 32 rotates with the first rotating shaft 31. The first abutting portion 321 of the cam structure 32 starts to rotate from the initial state of abutting against the second abutting surface 2212 and departing from the concave segment. When the first abutting portion 321 of the cam structure 32 abuts against the first inwardly recessed segment 2211a, the plug-in member 22 starts to move towards the inside of the buckle housing 21, and the insertion portion 222 starts to retract into the buckle housing 21. When the first abutting portion 321 of the cam structure 32 abuts against the inwardly protruding segment 2211b, the insertion portion 222 of the plug-in member 22 is completely retracted into the buckle housing 21, and the buckle assembly 20 is separated from the installation groove 101.

[0083] When it is necessary to install the buckle assembly 20 into the installation groove 101 again, the cam structure 32 continues to rotate with the first rotating shaft 31. The first abutting portion 321 of the cam structure 32 starts to rotate from the state of abutting against the inwardly protruding segment 2211b. When the first abutting portion 321 of the cam structure 32 abuts against the second inwardly recessed segment 2211c, the plug-in member 22 starts to move towards the outside of the buckle housing 21, and the insertion portion 222 starts to extend out of the buckle housing 21. When the first abutting portion 321 of the cam structure 32 abuts against the second abutting surface 2212, the insertion portion 222 of the plug-in member 22 is completely extended into the buckle housing 21, and the buckle assembly 20 is stably installed in the installation groove 101 again.

[0084] It can be understood that the degree of concavity of the inwardly protruding segment 2211b can be related to the length of the insertion portion 222. By reasonably setting the concave distance of the inwardly protruding segment 2211b, the insertion portion 222 can be completely retracted into the buckle housing 21 when the first abutting portion 321 abuts against the inwardly protruding segment 2211b.

[0085] To improve the connection stability between the latch assembly 20 and the mounting groove 101 of the bracket body 10, and to ensure that the latch assembly 20 can be stably connected to the bracket body 10 in the locked state. In some other embodiments, the latch assembly 20 includes two plug-in members 22 arranged along the axial direction of the first rotating shaft 31, and the plug-in portions 222 on the two plug-in members 22 are arranged in opposite directions along the radial direction of the first rotating shaft 31; the first rotating shaft 31 is provided with two cam structures 32 arranged along the axial direction of the first rotating shaft 31, and the two cam structures 32 are respectively engaged with the cam grooves 221 of the two plug-in members 22.

[0086] In this embodiment, by providing two plug-in members 22 and two cam structures 32, the two cam structures 32 respectively drive the two plug-in portions 222 to be inserted into the two plug-in grooves 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.

[0087] Specifically, please refer to Figure 8 , Figure 9 and Figure 10 , the plug-in members 22 are arranged along the axial direction of the first rotating shaft 31, and the two cam structures 32 are also arranged along the axial direction of the first rotating shaft 31, so that the two cam structures 32 can respectively drive the two plug-in members 22.

[0088] The two plug-in members 22 have the same structure, and the plug-in portions 222 of the two plug-in members 22 are arranged in opposite directions, so that both opposite sides of the latch housing 21 can extend the plug-in portions 222, and both sides of the latch assembly 20 can establish a connection relationship with the plug-in grooves 102 in the mounting groove 101. Similarly, the cam grooves 221 and the plug-in portions 222 on the two plug-in members 22 also have the same structure. The two cam structures 32 also have the same structure, and the two cam structures 32 can simultaneously drive the two plug-in members 22 and drive the plug-in portions 222 to disengage from the plug-in grooves 102 of the bracket body 10, ensuring the synchronization of the movement of the plug-in members 22 on both sides inside the latch housing 21.

[0089] Optionally, the two first abutting portions 321 of the two cam structures 32 are respectively located on opposite sides of the first rotating shaft 31, and the two second abutting portions 322 of the two cam structures 32 are respectively located on opposite sides of the first rotating shaft 31.

[0090] Specifically, the two first abutting portions 321 of the two cam structures 32 are arranged back to back, and the second abutting portions 322 of the two cam structures 32 are also arranged back to back. In addition, the two insertion portions 222 are arranged back to back within the latch housing 21. Therefore, the two cam structures 32 can simultaneously drive the two insertion portions 222 to insert into or withdraw from the insertion slot 102, ensuring the synchronization of the movement of the connectors 22 on both sides within the latch housing 21.

[0091] In another embodiment, at least two insertion portions 222 are formed at the end of the connector 22, and at least two first sockets 211 are provided on the latch housing 21 to respectively correspond to the at least two insertion portions 222.

[0092] Specifically, each connector 22 may include two insertion portions 222, and the two insertion portions 222 are arranged at intervals. Two first sockets 211 may be respectively provided at positions corresponding to the insertion portions 222 on one side surface of the latch housing 21 to allow the two insertion portions 222 to protrude. Since there are two connectors 22, at least two first sockets 211 are also formed on the other side surface of the latch assembly 20 to allow the two insertion portions 222 of the other connector 22 to pass through.

[0093] In order to make the latch assembly 20 have a more aesthetic appearance surface, after the latch assembly 20 is detached from the bracket body 10 along with the host body 40, no obvious welding points can be seen on the appearance of the latch assembly 20. In another embodiment, the latch housing 21 may include a first housing 212 and a second housing 213. The first housing 212 is provided with a first through opening 214 and a first opening 215 facing away from the rotation connection assembly 30; the second housing 213 closes the first opening 215, and a connection post 216 is provided on the side of the second housing 213 facing the first housing 212. The connection post 216 extends along the axial direction of the first rotating shaft 31 and is arranged to avoid the connector 22, and the connection post 216 is connected to the welding piece provided in the first through opening 214 to connect the second housing 213 to the first housing 212.

[0094] Please refer to Figure 9 , the latch housing 21 may include a first housing 212 and a second housing 213. The first housing 212 has a first opening 215, so that during installation, the first rotating shaft 31, the connector 22, and the buckle assembly 105 can be installed into the interior of the first housing 212 through the first opening 215.

[0095] Two first through openings 214 are further provided on the first housing 212, and the two first through openings 214 may be respectively located on both sides of the through hole of the first housing 212 for passing through the first rotating shaft 31. The first through opening 214 is used to accommodate the welding piece, and the welding piece may be a welding bead.

[0096] The second housing 213 is used to seal the first opening 215. A connecting post 216 is provided on the second housing 213. The connecting post 216 extends along the axial direction of the first rotating shaft 31 and can abut against the first through port 214 on the first housing 212. In this way, the connecting post 216 can be welded to the first housing 212 through the welding beads accommodated in the first through port 214, so that the second housing 213 and the first housing 212 are welded. Since the surface of the first housing 212 where the first through port 214 is provided faces the rotating connection assembly 30, even if a welding point is formed on the surface of the first housing 212 close to the rotating connection assembly 30, the welding point will be invisible to the user through the shielding of the rotating connection assembly 30, thus improving the overall aesthetics of the buckle assembly 20.

[0097] Considering that a movable plug-in member 22 is provided in the buckle housing 21, in order to avoid interfering with the movement of the plug-in member 22, the connecting post 216 needs to be arranged to avoid the plug-in member 22, and this avoidance can be achieved by providing a clearance area on the plug-in member 22. In another embodiment, an avoidance groove 224 is provided on the plug-in member 22. The avoidance groove 224 is located between the two plug-in parts 222, and the connecting post 216 is inserted into the avoidance groove 224 along the axial direction of the first rotating shaft 31.

[0098] An avoidance groove 224 is provided on the plug-in member 22. The avoidance groove 224 can be provided between the two plug-in parts 222, so as to reasonably utilize the space between the two plug-in parts 222 of the plug-in member 22, making the structural design of the plug-in member 22 more compact and enabling the further miniaturization of the buckle assembly 20.

[0099] Please refer to Figure 9 , the avoidance groove 224 provided on the plug-in member 22 can be used to form an avoidance with the connecting post 216, that is, the connecting post 216 can extend into the avoidance groove 224, the connecting post 216 will not interfere with the movement of the plug-in member 22, and can also make a firm connection between the first housing 212 and the second housing 213.

[0100] In order to further improve the connection stability between the buckle assembly 20 and the bracket body 10, in another embodiment, a buckle assembly 105 is provided on one of the bracket body 10 or the buckle assembly 20, and a card slot 217 is provided on the other of the bracket body 10 or the buckle assembly 20. The buckle assembly 105 and the card slot 217 can be detachably inserted.

[0101] For the assembly process of installing the buckle assembly 20 on the bracket body 10, the buckle assembly 20 can be pre-positioned in the installation slot 101 by inserting the buckle assembly 105 into the card slot 217. After the buckle assembly 105 extends into the card slot 217, the locking state of the buckle assembly 20 can be made more stable and reliable.

[0102] 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 32 on the first rotating shaft 31 drives the plug-in member 22 to move, thereby causing the plug-in portion 222 to disengage from the plug-in groove 102. After the plug-in portion 222 disengages from the plug-in groove 102, the buckle assembly 20 is in a detachable state as a whole. At this time, the buckle assembly 105 can provide a certain plugging force to hold the buckle housing 21 in the installation groove 101, thereby preventing the main body 40 of the host from being lost due to the loss of the locking relationship between the plug-in portion 222 and the plug-in groove 102 when the user does not pull out the main body 40 of the host from the bracket body 10.

[0103] Furthermore, the buckle assembly 105 is movably disposed on the bracket body 10. When the buckle assembly 105 is subjected to a pressure towards the inside of the installation groove 101, the buckle assembly 105 can retract into the installation groove 101. When the buckle housing 21 is placed in the installation groove 101 and the buckle assembly 105 corresponds to the card slot 217 provided on the buckle housing 21, the buckle assembly 105 can be reset to insert into the card slot 217.

[0104] Specifically, the buckle assembly 105 is movably disposed on the bracket body 10. When the buckle assembly 105 is subjected to a pressure towards the inside of the installation groove 101, the buckle assembly 105 can retract into the installation groove 101 of the bracket body 10. When the buckle housing 21 is placed in the installation groove 101 and the buckle assembly 105 corresponds to the card slot 217 provided on the buckle housing 21, the buckle assembly 105 can be reset to insert into the card slot 217.

[0105] Please refer to Figure 11 and Figure 12 As shown in FIGS. and, the bracket body 10 further includes a buckle assembly 105. A card slot 217 is provided at a corresponding position on the side wall of the buckle housing 21. The buckle assembly 105 is movably disposed in the bracket body 10. Similar to the plug-in member 22, the buckle assembly 105 can also retract into the bracket body 10 when it is subjected to a pressure towards the inside of the installation groove 101. When the buckle assembly 105 is aligned with the card slot 217, the buckle assembly 105 can be inserted into the card slot 217.

[0106] Optionally, a receiving groove is formed on the bracket body 10. The receiving groove communicates with the installation groove 101 through a second socket 104 provided on the groove wall of the installation groove 101. The buckle assembly 105 is movably disposed in the receiving groove, and at least a part of the buckle assembly 105 extends into the installation groove 101 from the second socket 104.

[0107] The receiving groove can be arranged at a position of the bracket body 10 close to the mounting groove 101. A second socket 104 is formed on the groove wall of the mounting groove 101 at a position corresponding to the buckle 106. The receiving groove communicates with the mounting groove 101 through the second socket 104. The buckle assembly 105 is movably arranged in the receiving groove, thus reasonably utilizing the space inside the bracket body 10 and enabling the locking assembly 20 to be further miniaturized.

[0108] Optionally, the buckle assembly 105 includes: a buckle 106, guiding inclined surfaces are respectively formed on both sides of the buckle 106 close to and away from the bottom of the mounting groove 101, and the buckle 106 can extend into the card slot 217 on the locking assembly 20 from the second socket 104; a first elastic member 107, one end of the first elastic member 107 is connected to the buckle 106, and the other end of the first elastic member 107 abuts against the groove wall of the receiving groove.

[0109] Please refer to Figure 12 , the buckle assembly 105 includes a buckle 106 and a first elastic member 107. One end of the first elastic member 107 abuts against the groove wall of the receiving groove, and the other end is connected to the buckle 106.

[0110] In this way, by the first elastic member 107 abutting against the groove wall of the receiving groove and connecting the buckle 106, the buckle 106 can be made to move relative to the second socket 104 provided on the groove wall of the mounting groove 101. When installing or disassembling the locking assembly 20 into or from the mounting groove 101, under the extrusion of the groove wall of the mounting groove 101, the buckle 106 can contract into the receiving groove, so that the locking housing 21 can be installed in the mounting groove 101 or disassembled from the mounting groove 101. When the locking housing 21 is located in the mounting groove 101, the buckle 106 is engaged in the card slot 217 of the locking housing 21 under the elastic action of the first elastic member 107, realizing the pre-positioning function of the locking assembly 20.

[0111] It should be noted that the buckle 106 has guiding inclined surfaces on both surfaces close to and away from the rotating connection assembly 30, that is, when the buckle 106 moves out of and into the card slot 217, the friction force between the buckle 106 and the side wall of the locking housing 21 can be reduced through the guiding inclined surfaces, so that the buckle 106 can be more easily retracted into the receiving groove.

[0112] Exemplarily, the first elastic member 107 can be a spring or a spring piece.

[0113] In another embodiment, the rotation connection assembly 30 further includes: a mounting base 33 and a second rotating shaft 338. The second rotating shaft 338 is disposed on the mounting base 33. The axis of the second rotating shaft 338 is perpendicular to the axis of the first rotating shaft 31. The second rotating shaft 338 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 338 are arranged at intervals. The first rotating shaft 31 is connected to the mounting base 33 to be connected to the main body 40 of the host through the mounting base 33 and rotate with the main body 40 of the host.

[0114] Please refer to Figure 8 and Figure 10 , the rotation connection assembly 30 further includes a mounting base 33 and a second rotating shaft 338. The second rotating shaft 338 is disposed on the mounting base 33. The second rotating shaft 338 is rotatably connected to the main body 40 of the host. For example, the second rotating shaft 338 is rotatably connected to a connecting member 339, and the connecting member 339 is fixed to the main body 40 of the host. The second rotating shaft 338 is used to make the main body 40 of the host flip relative to the bracket body 10. The first rotating shaft 31 is disposed on the mounting base 33 and is arranged at intervals with the second rotating shaft 338. The axis of the first rotating shaft 31 is perpendicular to the axis of the second rotating shaft 338. One end of the first rotating shaft 31 is connected to the mounting base 33 to be connected to the main body 40 of the host through the mounting base 33 and the second rotating shaft 338 and rotate synchronously with the main body 40 of the host. The other end of the first rotating shaft 31 extends towards the locking component 20, and a cam structure 32 is provided at one end extending into the locking component 20.

[0115] In this way, by providing the first rotating shaft 31 and the second rotating shaft 338 with perpendicular axes, when the main body 40 of the host is installed on 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 flipped relative to the bracket body 10 through the second rotating shaft 338, so as to meet various usage requirements of users. At the same time, by the rotation of the first rotating shaft 31, the plug-in member 22 is driven to disengage from the plug-in slot 102 on the bracket body 10, so as to make the locking component 20 detachable from the bracket body 10.

[0116] Optionally, a first gear portion 23 is formed on the surface of the latch housing 21 facing the rotary connection assembly 30. The first gear portion 23 includes a first gear protrusion 231 and a first gear recess 232. A second gear portion 34 is formed on the side of the mounting seat 33 facing away from the second elastic member 330. The second gear portion 34 further includes a second gear protrusion 341 and a second gear recess 342. During the process of the first rotating shaft 31 driving the plug member 22 to move out of the plug slot 102, the first gear protrusion 231 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 232 to abutting against the first gear protrusion 231. A second elastic member 330 is disposed within the mounting seat 33. The second elastic member 330 is sleeved on the first rotating shaft 31. During the process of the first rotating shaft 31 driving the plug member 22 to move out of the plug slot 102, the second elastic member 330 deforms along the axial direction of the first rotating shaft 31. The elastic force generated by the deformation of the second elastic member 330 is used to keep the first gear portion 23 and the second gear portion 34 in a pressed state.

[0117] Please refer to Figure 7 and Figure 9 As shown in, a first gear portion 23 is provided on the surface of the latch housing 21 facing the rotary connection assembly 30, and a second gear portion 34 is provided on the side of the mounting seat 33 facing the latch housing 21. The second gear portion 34 is used to cooperate with the first gear portion 23 when the cam structure 32 drives the plug member 22 to move out of the plug slot 102.

[0118] By providing the first gear portion 23 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 23 and the second gear portion 34 increases, causing the second elastic member 330 to be 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 23 and the second gear portion 34, the friction force between the mounting seat 33 and the latch assembly 20 can be increased, further enhancing the damping sensation.

[0119] Specifically, the first gear portion 23 includes a first gear protrusion 231 and a first gear recess 232, and the first gear protrusion 231 and the first gear recess 232 are connected by an inclined surface. The second gear portion 34 includes a second gear protrusion 341 and a second gear recess 342, and the second gear protrusion 341 and the second gear recess 342 are connected by an inclined surface.

[0120] When the host body 40 is mounted on the bracket body 10 and is in a stacked state, the first gear position concave portion 232 cooperates with the second gear position convex portion 341, and the first gear position convex portion 231 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 23. 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 231, and the second gear position concave portion 342 is opposite to the first gear position concave portion 232.

[0121] Since the distance between the first gear portion 23 and the second gear portion 34 increases compared to the state when the host body 40 is not rotated, the second elastic member 330 in the mounting seat 33 is compressed, and the elastic force generated by the compression of the second elastic member 330 keeps the first gear portion 23 and the second gear portion 34 in a pressed state. Therefore, during the relative movement of the first gear portion 23 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.

[0122] Optionally, the second elastic member 330 is a spring with a rectangular cross-section.

[0123] 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 second elastic member 330 is a rectangular cross-section spring, which can further reduce the outer diameter of the second elastic member 330 while generating the same elastic force.

[0124] In this way, the diameter of the first rotating shaft 31 can be further reduced. At the same time, the second elastic member 330 made of a rectangular cross-section spring can further reduce the space requirement, making the mounting seat 33 in the above embodiment more miniaturized.

[0125] In some embodiments, the mounting base 33 includes: a base body 331, a first through hole is provided on the base body 331, the first rotating shaft 31 is passed through the first through hole and extends into the locking assembly 20; two first frames 332, each first frame 332 is connected to the base body 331; a second frame 334, the first rotating shaft 31 is connected to the second frame 334, the second frame 334 covers the two first frames 332 and is respectively limitedly matched with the two first frames 332; one end of the second elastic member 330 abuts against the second frame 334, the other end of the second elastic member 330 abuts against the base body 331, and the second elastic member 330 is placed in the space enclosed by the second frame 334 and the two first frames 332.

[0126] In this embodiment, the mounting base 33 includes a base body 331, a first frame 332, and a second frame 334. The base body 331 is used to set a first through hole for the first rotating shaft 31. A second elastic member 330 is arranged in the space enclosed by the first frame 332, the second frame 334 and the base body 331. The second elastic member 330 is sleeved on the first rotating shaft 31. One end of the second elastic member 330 abuts against the second frame 334, and the other end abuts against the base body 331.

[0127] As shown in the embodiment provided by the present application, the mounting base 33 Figure 8 and Figure 14 shows that two first frames 332 are formed at two edges of the base body 331. The two first frames 332 extend in a direction away from the base body 331. The second frame 334 is covered above the two first frames 332, so that the second frame 334 and the first frame 332 are buckled to form a cover body for accommodating the first rotating shaft 31 and the second elastic member 330, reducing the occupation of space and enabling the rotating connection assembly 30 to be further miniaturized. At the same time, the saved space is used to strengthen the strength of the first frame 332, thereby enhancing the structural strength of the rotating connection assembly 30.

[0128] Further, the first frame 332 is arranged on the base body 331, and the first frame 332 and the second frame 334 are in limit cooperation. The first rotating shaft 31 is connected to the second frame 334. Therefore, a connection relationship is formed between the first rotating shaft 31 and the base body 331. When the base body 331 rotates with the main body 40, the first rotating shaft 31 can rotate synchronously with the main body 40 through the cooperation relationship among the base body 331, the first frame 332, and the second frame 334.

[0129] Optionally, a limit port 333 is arranged on one side of each first frame 332 facing away from the locking assembly 20; the second frame 334 includes two outward convex parts 335 arranged opposite to each other, and each outward convex part 335 is clamped in the limit port 333, and the outward convex part 335 does not protrude from the outer surface of the first frame 332.

[0130] Please refer to Figure 8, each of the two first frames 332 is provided with a limited opening 333, and the second frame 334 includes two outer protrusions 335 arranged opposite to each other. When the outer protrusions 335 are clamped in the second frame 334, a limited fit is formed between the first frame 332 and the second frame 334. At the same time, the second frame 334 is also provided with a limited hole 337, which is used to be limitedly connected with the first rotating shaft 31, thereby realizing a limited fit relationship between the seat body 331, the first frame 332, the second frame 334 and the first rotating shaft 31, and the first rotating shaft 31 can rotate synchronously with the host body 40. The outer protrusions 335 do not protrude from the outer surface of the first frame 332, which can further improve the structural compactness of the internal components of the rotating connection assembly 30.

[0131] In another embodiment, the mounting seat 33 also includes a boss 336 disposed on the seat body 331, the two bosses 336 are respectively located on both sides of the first through hole, the boss 336 is provided with a second through hole, and the second rotating shaft 338 is connected to the second through hole through a bushing and is at least partially exposed on the boss 336.

[0132] See also Figure 8 The seat body 331 has a boss 336 on one side facing away from the lock assembly 20, and the boss 336 has a second through hole extending therethrough, and the second shaft 338 is inserted through the second through hole through a shaft sleeve. In this way, the lock assembly 20, the first shaft 31, and the second shaft 338 are arranged on the side of the seat body 331 facing the lock assembly 20 and the side facing away from the lock assembly 20, respectively, so that the structure of the smart host 1 is compact.

[0133] It is understandable that in order to stably connect the host body 40 with the second rotating shaft 338, two second rotating shafts 338 can be provided. Similarly, two bosses 336 are also provided, and the two bosses 336 are respectively provided at two opposite sides of the first through hole, and the two bosses 336 are both provided with a second through hole, so that the two second rotating shafts 338 are respectively passed through the two second through holes and connected to the two ends of the host body 40, thereby improving the stability of the connection between the host body 40 and the second rotating shaft 338, so as to ensure the stability of the flipping movement of the host body 40 relative to the bracket body 10.

[0134] Optionally, the rotating connection assembly 30 also includes: a connecting member 339, which is used to connect to the host body 40, and one end of the second rotating shaft 338 exposed at the boss 336 is passed through the connecting member 339, and the connecting member 339 can rotate relative to the second rotating shaft 338 driven by the host body 40.

[0135] Specifically, the second rotating shaft 338 is fixed within the boss 336 through a bushing.

The connecting member 339 is configured as a bent structure, and the bent portion is connected to the main body 40 of the host, so that the connecting member 339 can rotate around the second rotating shaft 338 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.

[0136] 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, the protective cover 35 is disposed on the mounting seat 33 and covers the mounting seat 33; 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.

[0137] 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 338 and the mounting seat 33, and covers the mounting seat 33, so as to be able to protect the first rotating shaft 31 and the second rotating shaft 338.

[0138] It should be noted that, as described above, both the mounting seat 33 and the second elastic member 330 in the rotating connection assembly 30 provided in the present application have smaller sizes compared with the related art. Please refer to Figure 11 and Figure 12 , so that the mounting seat 33, the second elastic member 330 and the first rotating shaft 31 are all further miniaturized.

[0139] 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.

[0140] Specifically, the width D1 of the protective cover 35 can be 5.8 mm, 6 mm or 6.2 mm.

[0142] Please refer to Figure 13 and Figure 14 , because the structure of the plug-in member 22 in the embodiment of the present application is simple, compact and occupies little space, the size of the lock assembly 20 is also further reduced. Along the width direction of the mounting groove 101, the width of the lock housing 21 is D2, 4.8 mm ≤ D2 ≤ 5.2 mm.

[0143] Specifically, the width D2 of the lock housing 21 can be 4.8 mm, 5 mm or 5.2 mm.

[0145] It can be understood that the connection between the buckle assembly 20 and the bracket body 10 is realized by the clamping of the plug-in member 22 and the plug-in groove 102. In order to reduce the requirement for the structural strength of the plug-in member 22, a limiting boss 103 can also be provided in the mounting groove 101. The limiting boss 103 can be used to support the buckle assembly 20, thereby reducing the acting force generated by the gravity of the buckle assembly 20 on the plug-in member 22 and improving the service life of the buckle assembly 20.
