Description

Technical Field

[0001] This application relates to the field of electronic product technology, and in particular to an electronic system, adapter, external device, and docking device. Background Technology

[0002] Mobile phones have become necessities in people's daily lives. As mobile phones become thinner and lighter, the performance improvement of various functions of mobile phones and other terminal devices (such as photography, video recording, battery life, heat dissipation, communication, audio, computing, etc.) is often constrained by the limited size of the terminal devices. External functional components on terminal devices have gradually become a feasible solution.

[0003] To assemble external devices onto terminal equipment, a docking structure can be pre-installed on the terminal equipment's casing. However, without compromising the terminal equipment's appearance, issues often arise such as the docking structure being too small, the docking position being difficult to locate, or the docking being unstable. Improving the ease of use for users when assembling or detaching external devices from terminal equipment using docking structures is a pressing issue that needs to be addressed. Summary of the Invention

[0004] This invention provides an electronic system, an adapter component, an external device, and a docking device, which facilitate users in assembling and disassembling the corresponding devices.

[0005] In a first aspect, the present invention provides an electronic system including a terminal device and an external device. The terminal device includes a housing and a fixing member. The fixing member is fixedly connected to the housing and protrudes from the housing in a first direction. The protrusion of the fixing member in a second direction has a first surface and a second surface disposed opposite to each other. The second direction is perpendicular to the first direction. The second surface is located between the first surface and the housing, and a slot is formed on the side of the second surface facing the housing. The external device includes a latching assembly and a driving member. The latching assembly includes a clamping member, a bracket, and a movable claw. The clamping member is fixedly connected to the driving member. The bracket is clamped between the clamping member and the driving member in the first direction, and the two sides of the bracket abut against the clamping member and the driving member respectively in the first direction. The movable claw is movably connected to the bracket, and the driving member is rotatably connected to the bracket. When the driving member rotates relative to the bracket to a first position, the movable claw is located outside the slot, and the external device and the terminal device are in an unlocked state. When the driving member rotates relative to the bracket to a second position, at least a portion of the movable claw extends into the slot, and the external device and the terminal device are in a locked state. Understandably, when installing or removing external devices, the assembly and disassembly of the external devices are achieved by rotating the drive component. The end of the external device that is away from the terminal device is located in an open environment, closer to the user's grip position. Therefore, the user can freely grip any area of ​​the drive component to rotate it, making the disassembly and assembly of the electronic system easier to achieve and the operation more seamless. This solves the problem of users having difficulty holding the device, reduces the difficulty for users to locate and rotate the components, and improves the user experience.

[0006] In conjunction with the first aspect, the present invention provides an electronic system in which a first guide rail is provided on a driving component. The first guide rail includes a first end and a second end, and a movable claw has a locking member that cooperates with the first guide rail. During the rotation of the driving component relative to the support from a first position to a second position, the locking member moves from the first end to the second end; during the rotation of the driving component relative to the support from a second position to a first position, the locking member moves from the second end to the first end. The first guide rail can drive the claw to rotate to the end corresponding to the first or second position via the locking member when the driving component rotates, improving the motion continuity of the overall movable connection structure and realizing the switching between unlocked and locked states.

[0007] In combination with the first aspect and the above-described implementation, the present invention provides an electronic system in which the distance between the first guide rail and the rotation center line of the driving member gradually decreases in the direction from the first end to the second end. At this time, the movable pawl moves toward the rotation center line and can switch from a retracted position to an extended position.

[0008] In conjunction with the first aspect and the above-described implementation, the present invention provides an electronic system in which a movable claw is slidably connected to a bracket, and the sliding direction of the movable claw intersects with the rotation center line of the driving component. When the sliding direction of the movable claw intersects with the rotation center line, the movable claw can directly extend and retract in the radial direction of the bracket. The movement process of the movable claw is simple and easy to control, and the extension and retraction efficiency of the movable claw is high.

[0009] In conjunction with the first aspect and the above-described implementation, the present invention provides an electronic system in which a second guide rail is further provided on the driving component. The second guide rail is connected to the first end, and the distance between the second guide rail and the rotation center line of the driving component remains unchanged in the extension direction of the second guide rail. When the driving component rotates relative to the bracket to the first position, the locking component is located on the second guide rail. Alternatively, the driving component is further provided with a third guide rail, which is connected to the second end. The distance between the third guide rail and the rotation center line of the driving component remains unchanged in the extension direction of the third guide rail, and when the driving component rotates relative to the bracket to the second position, the locking component is located on the third guide rail. Understandably, the movable jaw can absorb the rotational tolerance of the driving component through the equal-diameter design of the second and third guide rails, reducing the accuracy requirements for the rotational action of the driving component and ensuring the full-stroke displacement of the movable jaw. This ensures the reliability of the movable jaw in unlocking or locking the terminal device and improves the user's operating experience. At the same time, when the locking component is located in the second or third guide rail, the second or third guide rail can limit the position of the locking component, preventing the locking component from sliding along the first guide rail and affecting the stability of the movable jaw in the unlocked or locked state.

[0010] In conjunction with the first aspect and the above-described implementation, the present invention provides an electronic system in which a bracket includes a first component. The first component has a ring-shaped structure, and a corresponding limiting groove is formed on a driving member. The inner edge of the first component abuts against a clamping member and the limiting groove at both ends in a first direction, respectively. The clamping member and the limiting groove apply pressure by abutting against the first component at both ends in the first direction to limit the position of the bracket, thereby ensuring that the relative positions of the clamping member and the driving member with respect to the bracket in the radial direction remain relatively stable when they rotate.

[0011] In conjunction with the first aspect and the above-described implementation, the present invention provides an electronic system in which a fixing member has a light-transmitting hole, and a terminal device further includes a light-transmitting member covering the light-transmitting hole; a driving member covers a first surface and the light-transmitting hole; or, the driving member covers the first surface and avoids the light-transmitting hole. When the driving member covers the first surface and the light-transmitting hole, the shape and height of the driving member in the first direction can be set more freely; when the driving member avoids the light-transmitting hole, the lens of the terminal device can be prevented from being blocked, and the user can still use the camera function of the terminal device normally.

[0012] In conjunction with the first aspect and the above-described implementation, the present invention provides an electronic system in which a driving component includes a driving part and a driving body. The driving body is fixedly connected to the driving part, and the driving body is fixedly connected to a clamping member via the driving part. The driving body is disposed on the side of the driving part facing away from the clamping member in a first direction, or the driving body is disposed on the side of the driving part facing away from the clamping member in a second direction. The driving body can be configured as a functional component that cooperates with a terminal device, and different external functional components often correspond to different external connection methods. The driving body can further broaden the application scope and field of the terminal device, and enhance its functionality.

[0013] In conjunction with the first aspect and the above-described implementation, the present invention provides an electronic system in which the latching assembly further includes a shielding portion, which surrounds the outer periphery of the bracket and is fixedly connected to the bracket; or, the shielding portion surrounds the outer periphery of the bracket and is fixedly connected to the driving component. The shielding portion serves to shield the connecting structure composed of the bracket, the movable claw, and the clamping component, not only providing waterproofing, dustproofing, and preventing foreign objects from affecting the movable connection relationship of the three components, but also reducing external impacts on the three components and protecting the reliability of the overall structure.

[0014] Combining the first aspect and the above-described implementation, the present invention provides an electronic system in which a notch is formed in the bracket; the movable claw includes a first arm extending in a circumferential direction and a claw disposed in a first direction, with a locking member and the claw respectively located at both ends of the first arm in the first direction, and the locking member or a first guide rail passing through the notch. The claw is used to engage in a slot to improve the stability between the latching assembly and the terminal device. At the same time, the first arm, as an extension in the circumferential direction of the bracket, can drive the locking member to move, thereby making the movable claw's movement more efficient and its movement trajectory smoother.

[0015] In conjunction with the first aspect and the above-described implementation, the present invention provides an electronic system in which the movable claw further includes a second arm, the second arm and the claw being fixed to the first arm at intervals and protruding towards the same side of the first arm; the bracket includes a first sliding groove and a second sliding groove arranged at intervals and opposite to each other, the first sliding groove and the second sliding groove being arranged in the circumferential direction of the bracket, and the two ends of the second arm being slidably connected to the first sliding groove and the second sliding groove respectively. In this case, the sliding motion of the movable claw relative to the bracket is more stable.

[0016] In conjunction with the first aspect and the above-described implementation, this invention provides an electronic system in which at least a portion of the first arm is made of metal, and the claw is made of hard plastic. The claw and the first arm are integrally formed structural components. The first arm has high structural strength, which helps ensure the overall structural strength of the movable claw. The claw experiences less wear when engaging with other structures, which helps ensure the reliability of the claw. The connection strength between the claw and the first arm is high, which helps improve the structural reliability of the movable claw. For example, the claw and the first arm can be integrally formed using insert injection molding.

[0017] In conjunction with the first aspect and the above-described implementation, the present invention provides an electronic system. A first arm includes an arm body and an insert. The insert includes a first part, a second part, and a third part. The first part is embedded on a first side of the arm body, the second part is embedded on a second side of the arm body, and the third part connects the first and second parts. A claw is connected to the second part. The arm body is made of metal, and the insert is made of rigid plastic. By designing the structure of the insert and the mating structure between the insert and the arm body, the connection area between the insert and the arm body is increased, and the connection strength between them is higher, thereby resulting in a higher connection strength between the claw and the first arm.

[0018] Combining the first aspect and the above-described implementation, the present invention provides an electronic system with multiple movable claws arranged at intervals along the circumference of a bracket. Each movable claw is connected to both the bracket and a driving component. When the driving component rotates relative to the bracket, the multiple movable claws move synchronously. Because the multiple movable claws move synchronously during the rotation of the rotating ring relative to the bracket, they can cooperate to lock and unlock the terminal device, thereby improving the reliability of the electronic system.

[0019] In conjunction with the first aspect and the above-described implementation, the present invention provides an electronic system in which the external device further includes an elastic element. The elastic element is fixed to one end of the clamping member and located inside the bracket. When the external device is connected to the terminal device, the elastic element abuts against the terminal device and is in a compressed state. Because the elastic element of the external device abuts against the terminal device and is in a compressed state, the elastic element can absorb the assembly tolerance between the movable claw and the fixing member of the terminal device in the first direction, so that the movable claw can be stably engaged with the fixing member of the terminal device, avoiding loosening, shaking, or falling off. The locking state between the external device and the terminal device is reliable.

[0020] In conjunction with the first aspect and the above-described implementation, the present invention provides an electronic system in which the elastic element is a ring-shaped silicone element; the elastic element abuts against the periphery of the light-transmitting element. In this case, the connection structure between the light-transmitting element, the elastic element, and the external device is stable and reliable.

[0021] In conjunction with the first aspect and the above-described implementation, the present invention provides an electronic system in which a wedge-shaped engagement structure is formed between the second surface and the movable claw. In this case, the overlap area between the second surface and the movable claw is large, resulting in better overlap stability, which is beneficial for ensuring the reliability of the locking state between the external device and the terminal equipment.

[0022] Combining the first aspect and the above-described implementation, the present invention provides an electronic system in which a movable claw has a engaging surface for engaging with a second surface. The end of the engaging surface is near the slot, and the end of the second surface is near the movable claw. When the movable claw is outside the slot, in a first direction, the end of the engaging surface is located between the end of the second surface and the outer casing, and there is a first distance between the end of the engaging surface and the end of the second surface. When the movable claw extends into the slot, in the first direction, there is a second distance between the end of the engaging surface and the end of the second surface. The difference between the second distance and the first distance is less than the maximum compression of the elastic element. When the driving member rotates relative to the bracket from a first position to a second position, the movable claw can smoothly engage into the slot, and the elastic element can completely absorb the assembly tolerance between the movable claw and the fixing member in the first direction, allowing the movable claw to smoothly engage the fixing member. The maximum compression of the elastic element refers to the maximum deformation that the elastic element can undergo when subjected to external force.

[0023] In conjunction with the first aspect and the above-described implementation, the present invention provides an electronic system in which, when the external device is connected to the terminal device, the bracket remains stationary after contacting the first surface. Therefore, the external device will not cause wear to the first surface due to its locking and unlocking actions, allowing the first surface to maintain its good appearance and avoiding aesthetic problems caused by wear on the fastener's surface. This results in a longer service life for the electronic system. Furthermore, the surface in the terminal device that rubs against the movable claw of the external device is the wall of the slot (such as the second surface), and the slot is a hidden structure, making the worn surface invisible and minimizing its adverse impact on the appearance of the terminal device.

[0024] Combining the first aspect and the above-described implementation, this invention provides an electronic system in which a fixing member has a protrusion, a through hole is formed in the center of the bracket, and a positioning groove is provided on one of the side wall of the protrusion near the first surface and the inner wall of the through hole, while a positioning block is provided on the other. When the external device is docked with the terminal device, the positioning groove and the positioning block cooperate for positioning. When the external device is docked with the terminal device, the positioning block and the positioning groove can serve as a pre-positioning mating structure, enabling the external device to accurately dock with the terminal device, so that the movable claw can subsequently engage with the slot and lock. In addition, after the external device is docked with the terminal device, since the bracket and the fixing member are relatively fixed through the positioning block and the positioning groove, the user does not need to perform additional fixing operations on the bracket. The user can directly rotate the rotating ring to achieve the subsequent locking action. The user can lock the external device with one hand, which is convenient and provides a good user experience. Furthermore, after the external device is locked with the terminal device, the cooperation between the positioning block and the positioning groove can also increase the stability of the locking state between the external device and the terminal device, reducing the risk of the external device becoming loose, shaking, or falling off.

[0025] Combining the first aspect and the above-described implementation, the present invention provides an electronic system in which the length of the positioning groove along the first surface is greater than the length of the positioning block. The positioning block has a certain amount of room to move within the positioning groove, allowing for a certain degree of error when pre-positioning via the positioning block and the positioning groove. As long as the positioning block remains within the positioning groove range, accurate docking between the external device and the terminal equipment can still be achieved, reducing the difficulty of assembly and alignment and facilitating user operation.

[0026] In combination with the first aspect and the above-described implementation, the present invention provides an electronic system in which a clearance groove is formed on the edge of the clamping component, the position of the clearance groove corresponds to the positioning block, and the length of the clearance groove along the circumferential direction of the clamping component is greater than the length of the positioning block.

[0027] In conjunction with the first aspect and the above-described implementation, the present invention provides an electronic system in which a bracket has an abutment surface for abutting a first surface, the hardness of which is less than the hardness of the first surface. The electronic system employs a differentiated hardness design between the outer surface of the terminal device and the contact surface of the external device, ensuring that the hardness of the contact surface of the external device is less than the hardness of the outer surface of the terminal device. This reduces scratches or wear on the outer surface of the terminal device even if the external device slides relative to the outer surface of the terminal device during docking, thus helping to maintain the shape of the terminal device's outer surface and extending its service life.

[0028] In conjunction with the first aspect and the above-described implementation, the present invention provides an electronic system in which the hardness of the bracket is less than the hardness of the fixing member; or, the bracket includes a second member having an abutment surface, the hardness of the second member being less than the hardness of the fixing member. It is understood that the overall surface hardness of the bracket, or the surface hardness of the second member, is lower than the surface hardness of the fixing member, thereby reducing wear on the surface of the fixing member.

[0029] In conjunction with the first aspect and the above-described implementations, the present invention provides an electronic system in which the bracket is made of rigid plastic and the fastener is made of metal; or, the bracket is made of aluminum alloy and the fastener is made of titanium alloy; or, the bracket includes a second component with an abutment surface, the second component being made of rigid plastic and the fastener being made of metal; or, the second component being made of aluminum alloy and the fastener being made of titanium alloy. By using different materials, differentiated hardness settings are achieved on the surfaces of the bracket and the fastener.

[0030] In conjunction with the first aspect and the above-described implementation, the present invention provides an electronic system. The external device further includes a limiting member, which is disposed between the bracket and the driving member, or between the bracket and the clamping member. When the driving member rotates relative to the bracket to a first position or a second position, the limiting member engages the bracket and the driving member, or engages the bracket and the clamping member. It is understood that the limiting member not only increases the stability of the relative position between the driving member and the bracket, thereby increasing the stability of the locking or unlocking of the movable claw, but also provides tactile feedback through changes in the state of the limiting member, allowing the user to easily perceive whether the driving member has rotated to the correct position, thus improving the operational feel of the electronic system and providing a better user experience.

[0031] In conjunction with the first aspect and the above-described implementation, the present invention provides an electronic system in which the limiting member is an elastic connector and is disposed between a bracket and a driving member, wherein: one of the bracket and the driving member is provided with a first recess, and when the driving member rotates relative to the bracket to a first position, one end of the limiting member is engaged in the first recess; or one of the bracket and the driving member is provided with a second recess, and when the driving member rotates relative to the bracket to a second position, one end of the limiting member is engaged in the second recess, wherein the elastic connector is in a partially compressed state when engaged in the first or second recess.

[0032] By setting the limiting member as an elastic connector, and allowing it to engage with the recessed first or second recess for locking, the limiting member undergoes significant deformation when switching from a locked to a locked state, and collides with the groove wall of the first or second recess. This provides tactile and auditory feedback, improving the user experience. Furthermore, the stable engagement structure between the elastic limiting member and the first or second recess helps maintain the stability of the drive component's position in both unlocked and locked states, thereby improving the reliability of unlocking and locking of the external device.

[0033] Combining the first aspect and the above implementation method, the outer surface of the drive component is provided with an unlock mark and a lock mark, the outer surface of the drive component is provided with a first mark, and the outer shell is provided with a second mark; when the drive component is in the first position relative to the bracket, the first mark is aligned with the unlock mark and the second mark; when the drive component is in the second position relative to the bracket, the first mark is aligned with the lock mark. The unlock mark / lock mark, the first mark, and the second mark form a three-segment alignment mark. By setting the three-segment alignment mark, the electronic system can improve the user's operational convenience.

[0034] In conjunction with the first aspect and the above-described implementation, the present invention provides an electronic system in which the first surface is an annular surface, and neither the inner nor outer annular edge of the first surface has a groove or protrusion structure. The good shape integrity of the first surface reduces limitations on the appearance design of the fasteners, increases flexibility, and improves the user experience of the terminal device.

[0035] Secondly, the present invention provides an adapter assembly, including a driving component and a snap-fit ​​assembly. The snap-fit ​​assembly includes a clamping component, a bracket, and a movable claw. The clamping component is fixedly connected to the driving component. The bracket is sandwiched between the clamping component and the driving component in a first direction, and its two sides in the first direction abut against the clamping component and the driving component, respectively. The first direction is parallel to the thickness direction of the adapter assembly. The movable claw is movably connected to the bracket, and the driving component is rotatably connected to the bracket. When the driving component rotates relative to the bracket to a first position, the adapter assembly is in an unlocked position, and there is a first distance between the movable claw and the rotation center line of the driving component. When the driving component rotates relative to the bracket to a second position, the adapter assembly is in a locked position, and there is a second distance between the movable claw and the rotation center line of the driving component. The first distance is greater than the second distance. It is understood that the adapter assembly can solve the problem of difficult user grip operation. When assembling or disassembling the adapter assembly and the corresponding device, the driving component provides the user with a more flexible and easier-to-position grip area, improving grip operation and the convenience of rotation operation.

[0049] Thirdly, the present invention provides an external device, including a drive body and the aforementioned adapter assembly, wherein the drive body is fixedly connected to the drive component and moves synchronously with the drive component.

[0050] Understandably, different external functional components often correspond to different external connection methods, such as magnetic attachment, electrical connection via charging port, and snap-fit ​​connection via external structure. Therefore, separate drive bodies and drive components are set up. The drive components are used to connect with the corresponding devices, and a universal connection structure can be set on the drive components. This allows for flexible configuration of various drive bodies to connect to the drive components and cooperate with the corresponding devices. For example, an external lens can be set up by covering the fixing component, or an external power supply can be set up by avoiding the fixing component, etc., to meet different user needs.

Furthermore, the aforementioned functional components can also be disposed within the cavity, working in conjunction with the terminal device through the electrical signal interface, thereby improving the versatility of the driving body.

[0052] Fourthly, the present invention provides a docking device, including a fixing member and an adapter assembly. The thickness direction of the fixing member is parallel to a first direction.

When the driving member rotates relative to the bracket to a second position, at least a portion of the movable claw extends into the groove, and the adapter assembly is in a locked position. The interaction between the adapter and the fixing component allows the end of the drive component facing away from the fixing component to be located in an open environment, closer to a position that is easy for the user to hold. This reduces the difficulty of positioning and holding the adapter when assembling or disassembling it, thus improving the user experience.

Detailed Implementation

[0062] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to also include expressions such as “one or more,” unless the context clearly indicates otherwise. It should also be understood that in the following embodiments of this application, “at least one” and “one or more” refer to one or more (including two). The term “and / or” is used to describe the relationship between related objects, indicating that three relationships can exist; for example, A and / or B can indicate: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character “ / ” generally indicates that the preceding and following related objects are in an “or” relationship.

[0063] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized. The term "connection" includes both direct and indirect connections, unless otherwise stated.

[0064] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the embodiments of this application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplarily" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of words such as "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0065] Please refer to the following: Figures 1A to 1D , Figure 1A This is a schematic diagram of the structure of an electronic system 100 in a disassembled state, as provided in an embodiment of this application. Figure 1B This is a schematic diagram of an electronic system in a disassembled state, provided in an embodiment of this application. Figure 1C yes Figure 1A The diagram shown is a structural schematic of the electronic system 100 in the unlocked state. Figure 1D yes Figure 1A The diagram shows the structure of the electronic system 100 in the locked state.

[0066] In some embodiments, the electronic system 100 includes a terminal device 1 and an external device 2. The external device 2 can be detachably connected to the terminal device 1.

[0067] like Figure 1A As shown, the external device 2 is separated from the terminal device 1, and the electronic system 100 is in a disconnected state; Figure 1C As shown, the external device 2 is connected to the terminal device 1, and the two can be separated at this time, with the electronic system 100 in an unlocked state; as Figure 1D As shown, the external system is connected to the terminal device 1, and the two are fixed to each other at this time, with the electronic system 100 in a locked state.

[0068] When the electronic system 100 is in the disengaged state, the external device 2 can dock with the terminal device 1 through the housing structure of the terminal device 1. The external device 2 may include a driving component 2a. When the electronic system 100 is in the unlocked state, the external device 2 can rotate the driving component 2a (as shown by arrow a in 1B) to engage its bottom structure with the terminal device 1 (the engagement structure of the external device 2 and the terminal device 1 is described later), fixing the external device 2 to the terminal device 1, and switching the electronic system 100 from the unlocked state to the locked state. When the electronic system 100 is in the unlocked state, the external device 2 can detach from the terminal device 1, causing the electronic system 100 to be in a disengaged state. When the electronic system 100 is in the locked state, the external device 2 can be docked with the terminal device 1 by rotating the external device 2a in the reverse direction (as shown by arrow a in 1B). Figure 1D As shown by arrow b), the connection between the internal structure of the external device 2 and the terminal device 1 is released, and the external device 2 and the terminal device 1 are in a separable state. The electronic system 100 switches from the locked state to the unlocked state.

[0069] For example, terminal device 1 is a device that can be used independently. For instance, terminal device 1 can be a mobile phone, tablet personal computer, laptop computer, smart screen, personal digital assistant (PDA), camera, personal computer, laptop computer, in-vehicle equipment, wearable device, augmented reality (AR) glasses, AR headset, virtual reality (VR) glasses, or VR headset, etc. In the following embodiments, a mobile phone is used as an example for terminal device 1. Of course, other types of terminal devices 1 can also adopt a similar structure, which will not be elaborated further in this application.

[0070] For example, the external device 2 can work in conjunction with the terminal device 1 to provide the terminal device 1 with more powerful or additional functions. For instance, the external device 2 can be a larger professional lens to provide the terminal device 1 with stronger shooting capabilities; the external device 2 can be a power bank with charging capabilities to provide the terminal device 1 with longer battery life; the external device 2 can be a computing power bank with computing power to provide the terminal device 1 with stronger computing power; the external device 2 can be a heat dissipation device to cool the terminal device 1; or, the external device 2 can be a container for holding other devices. The external device 2 can also be other functional devices, which will not be listed in detail in this example. In the following embodiments, the external device 2 is described as a lens and a device including a container space. Of course, other types of external devices 2 can also adopt similar structures, which will not be elaborated upon in this application.

[0071] In this embodiment, when the terminal device 1 of the electronic system 100 requires the expansion function of the external device 2, the terminal device 1 and the external device 2 can be assembled together, realizing the transformation of ordinary terminal device into professional device. This breaks through the limitations of the compact and miniaturized structural size of current terminal devices (such as portable terminal devices), and expands the innovative form and professional functions of the terminal device 1. When the terminal device 1 does not need to use the expansion function of the external device 2, the external device 2 can be detached from the terminal device 1 to facilitate independent use of the terminal device 1. Therefore, it is easy to realize the miniaturized design of the terminal device 1, which combines portability and strong functionality.

[0072] It is understood that the accompanying drawings of the embodiments of this application only schematically show some components included in the terminal device 1 and the external device 2. The actual shape, size, position and structure of these components are not limited by the drawings. The terminal device 1 and / or the external device 2 may also include more or fewer components than those shown in the drawings.

[0073] It should be noted that the driving component 2a in this embodiment includes a driving part 21 (e.g., Figures 2A to 3B As shown), when installing or removing the external device 2, the rotation of the drive unit 2a is achieved by rotating the drive unit 21. The end of the external device 2 that is away from the terminal device 1 is located in an open environment, so the user can freely hold any area of ​​the drive unit 2a to rotate the drive unit 21, thereby making the disassembly and assembly of the electronic system 100 easier and improving the user experience.

[0074] Please refer to the following: Figure 1A , Figures 2A to 3D , Figure 2A yes Figure 1C The schematic diagram shows a cross-sectional structure of the electronic system 100. Figure 2B yes Figure 2A The diagram shows a cross-sectional view of a portion of the electronic system 100. Figure 2C yes Figure 1B A partial cross-sectional structural diagram of the electronic system shown. Figure 2D yes Figure 2C A cross-sectional structural diagram of the selected portion of the electronic system shown. Figure 3A yes Figure 1D The schematic diagram shows a cross-sectional structure of the electronic system 100. Figure 3B yes Figure 3A The diagram shows a cross-sectional view of a portion of the electronic system 100. Figure 3C yes Figure 1B The diagram shows a partial cross-sectional structure of the electronic system. Figure 3D yes Figure 3C The diagram shows a cross-sectional view of the selected portion of the electronic system.

[0075] For ease of description, a first direction and a second direction are defined below. The first direction, such as the Z direction, can be parallel to the thickness direction of the electronic system 100. The second direction, such as the X direction, can be a direction perpendicular to and intersecting the first direction. It should be understood that the direction perpendicular to the first direction is not the only determined direction; in other words, the X direction includes multiple directions perpendicular to and intersecting the first direction. The thickness direction of the terminal device 1 is consistent with the thickness direction of the electronic system 100. In the relevant descriptions below, the side of the terminal device 1 and its components and structures closer to the external device 2 in the first direction Z is called the "top," and the side farther from the external device 2 is called the "bottom." The side of the external device 2 and its components and structures farther from the terminal device 1 is called the "top," and the side closer to the terminal device 1 is called the "bottom." In other embodiments, the coordinate system settings of the terminal device 1 and the external device 2 can also be flexibly set according to specific actual needs.

[0076] Terminal device 1 may have a hidden card slot 11. In the first direction Z, when viewed from an open environment, the card slot 11 is concealed by the exterior surface of terminal device 1. External device 2 may include a clamping fastener 24, a bracket 23, and a movable claw 22 linked to the drive unit 21. When the drive unit 21 rotates, the position of the movable claw 22 changes with the movement of the drive unit 21. For example, the movable claw 22 may change position in the second direction X, and it may move between a retracted position and an extended position. Figures 2A to 2D As shown, when the electronic system 100 is in the unlocked state, the movable claw 22 is in the retracted position, and the movable claw 22 of the external device 2 is located outside the slot 11 of the terminal device 1. The external device 2 and the terminal device 1 are not engaged and can be separated from each other. Figure 3A and Figure 3BAs shown, when the electronic system 100 switches from the unlocked state to the locked state, after the drive unit 21 rotates, the movable claw 22 of the external device 2 is displaced in the second direction X. The movable claw 22 is in the extended position and extends into the slot 11 of the terminal device 1. The external device 2 and the terminal device 1 are engaged and fixed to each other.

[0077] In some embodiments, terminal device 1 may include a screen (not shown), a housing 12, and a fastener 13. The screen is used to display images, videos, etc. The screen may include a light-transmitting panel and a display screen. The light-transmitting panel and the display screen are stacked and fixedly connected. The light-transmitting panel mainly serves to protect the display screen and prevent dust. The material of the light-transmitting panel includes, but is not limited to, glass. The display screen can be a flexible display screen or a rigid display screen. For example, the display screen can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MLED) display screen, a micro organic light-emitting diode (MOLED) display screen, a quantum dot light-emitting diode (QLED) display screen, a liquid crystal display (LCD), etc.

[0078] For example, the housing 12 is used to protect the internal electronic components of the terminal device 1. The housing 12 can be made of materials such as metal, plastic, and glass. The housing 12 can be a plate made of a single material, or a plate structure made of multiple materials and spliced ​​together from multiple plates.

[0079] In some embodiments, the fastener 13 is fixedly connected to the housing 12 and protrudes outward in the direction away from the screen along the first direction Z; in other embodiments, the fastener 13 and the housing 12 may also be integrally formed structural components to improve the support capacity of the fastener 13.

[0080] In some embodiments, the fastener 13 may include a protrusion 133, a light-transmitting hole 131, and a light-transmitting element 132. The protrusion 133 is annular and is arranged along the second direction (X). The light-transmitting hole 131 is opened in the center of the protrusion 133, and the light-transmitting element 132 is installed in the light-transmitting hole 131.

[0081] For example, the protrusion 133 can be designed as a ring, such as a circular ring, a square ring, a triangular ring, a polygonal ring, or an elliptical track ring, or it can be designed as a ring of other shapes. It should be understood that the periphery of the ring may include arc-shaped edges, straight edges, or combinations thereof, and this application does not impose any special restrictions on this.

[0082] A light-transmitting hole 131 is located at the center of the fixing member 13, and a light-transmitting member 132 is fixed to the fixing member 13 and covers the light-transmitting hole 131. The light-transmitting member 132 allows light from objects to pass through and enter the terminal device 1. For example, the light-transmitting member 132 can be made of transparent materials such as glass or plastic. For example, the light-transmitting member 132 can be fixedly connected to the fixing member 13 by a first adhesive member 136. In some other examples, the light-transmitting member 132 can also be an integrally formed structural component with the fixing member 13, resulting in a stronger connection between the two.

[0083] In some embodiments, terminal device 1 may further include a camera device (not shown).

[0084] For example, the camera device is used to capture photos / videos. The camera device is mounted inside the housing 12. The camera device can be used as a rear-facing camera. For example, the light-incident surface of the camera device faces the fixing member 13. The fixing member 13 can be used to protect the camera device. The light-transmitting member 132 is used to allow light from outside the housing 12 to enter the light-incident surface of the camera device.

[0085] In other embodiments, terminal device 1 may also include one or more other camera modules (not shown), which are not strictly limited in this application. For example, terminal device 1 may also include another camera device used as a front-facing camera. In this case, the light-incident surface of the camera device faces the screen. The display screen is provided with a light-path obstruction hole. This light-path obstruction hole allows light from the scene to pass through the screen and enter the light-incident surface of the camera device.

[0086] In some embodiments, the terminal device 1 may further include a circuit board (not shown) and an image processor (not shown), which are mounted within the housing 12. The image processor is fixed to and electrically connected to the circuit board. The image processor is communicatively connected to the camera device. The image processor is used to acquire image data from the camera device and process the image data. The communication connection between the camera device and the image processor may include data transmission via electrical connections such as wiring, or data transmission may be achieved through coupling or other means. It is understood that the camera device and the image processor may also achieve a communication connection through other methods capable of data transmission.

[0087] In some embodiments, terminal device 1 may further include an analog-to-digital converter (also known as an A / D converter, not shown). The analog-to-digital converter is connected between the camera device and the image processor. The analog-to-digital converter is used to convert the signal generated by the camera device into a digital image signal and transmit it to the image processor, which then processes the digital image signal and finally displays the image or video on the screen.

[0088] In some embodiments, the terminal device 1 may further include a memory (not shown), which is communicatively connected to the image processor. The image processor processes the digital image signal and then transmits the image to the memory, so that the image can be retrieved from the memory and displayed on the screen at any time when it is needed to view the image later. In some embodiments, the image processor may also compress the processed digital image signal before storing it in the memory to save memory space.

[0089] It is understood that the structure of terminal device 1 in the above figures is only schematic, and terminal device 1 may include more or fewer components. For example, terminal device 1 may not include a screen. For example, terminal device 1 may not include a camera module, etc.

[0090] It is understood that the installation position of the fastener 13 of the terminal device 1 in the above figures is merely illustrative, and this application does not strictly limit the installation position of the fastener 13. In some other embodiments, the fastener 13 may also be installed in other positions of the terminal device 1, for example, the fastener 13 may be installed in the upper left corner of the back of the terminal device 1.

[0091] For example, the fastener 13 may have a first surface 13a and a second surface 13b disposed opposite to the first surface 13a.

[0092] Please refer to the following: Figures 4A to 6B , Figure 4A yes Figure 1A The diagram shows a top view of the terminal device in some embodiments. Figure 4B yes Figure 3C The diagram shows a partial structural schematic of the terminal device. Figure 5A yes Figure 4A The diagram shows the structure of the terminal device. Figure 5B yes Figure 4A The second schematic diagram of the terminal device shown is as follows. Figure 6A yes Figure 5A A cross-sectional structural diagram of the terminal device shown. Figure 6B yes Figure 6A A cross-sectional structural diagram of the selected portion of the electronic system shown. Figure 6C yes Figure 4B A cross-sectional structural diagram of the terminal device shown. Figure 6D yes Figure 6C The diagram shows a cross-sectional view of a selected portion of the electronic system. The fastener 13 includes a protrusion 133 extending in a second direction X. The protrusion 133 has a first surface 13a and a second surface 13b disposed opposite to each other, wherein the first surface 13a faces the top side of the protrusion 133. For example, the first surface 13a may surround the protrusion 134. In some examples, one end of the first surface 13a near the outer peripheral side of the protrusion 133 may be inclined towards the bottom side of the protrusion 133 relative to the other end of the first surface 13a.

[0093] The second surface 13b is disposed facing the bottom side of the protrusion 133, that is, the first surface 13a and the second surface 13b are disposed facing away from the protrusion 133.

[0094] In some examples, one end of the second surface 13b near the outer peripheral side of the protrusion 133 is inclined toward the top side of the protrusion 133 relative to the other end of the second surface 13b.

[0095] The fastener 13 may also have a third surface 13c, which is located on the protrusion 133 and disposed towards the bottom side of the protrusion 133. The third surface 13c is located inside the second surface 13b and is connected to the second surface 13b.

[0096] It should be noted that the inner side refers to the side that extends radially toward the rotation center line 211.

[0097] For example, the housing 12 may be provided with an annular protrusion 121, which protrudes from the side of the housing 12 opposite to the screen and surrounds the fixing member 13. By providing the annular protrusion 121, the housing 12 can increase its structural strength, thereby improving the structural reliability of the housing 12. The protrusion 133 can abut against the annular protrusion 121; for example, the third surface 13c can abut against the annular protrusion 121. In this case, the fixing member 13 and the housing 12 can maintain a stable relative positional relationship in the first direction Z.

[0098] Of course, in some other examples, the outer shell 12 may not have the annular protrusion 121, and the side of the outer shell 12 that fixes the fastener 13 may be a flat plate. This embodiment of the application does not strictly limit this. In this case, the protrusion 133 may be spaced apart from the outer shell 12, or the protrusion 133 may abut against the outer shell 12. This embodiment of the application does not strictly limit this.

[0099] For example, a groove 11 is formed on the side of the second surface 13b of the fastener 13 facing the housing 12. In other words, the groove 11 is formed on the side of the second surface 13b facing away from the first surface 13a. For example, the groove 11 may be formed between the second surface 13b of the fastener 13 and the housing 12. In this case, the second surface 13b forms part of the wall of the groove 11, and a local area of ​​the outer surface of the housing 12 forms another part of the wall of the groove 11. In some examples, the groove 11 may extend along the circumferential direction of the fastener 13 to form a complete annular structure.

[0100] In this embodiment, a portion of the structure of the fastener 13 covers the slot 11 in the first direction Z. For example, the first surface 13a covers the slot 11 in the first direction Z. Of course, in some other embodiments, the first surface 13a may also cover the slot 11 in the first direction Z together with other structures of the fastener 13.

[0101] In other examples, the slot 11 is located on the side of the fastener 13 facing away from the light-transmitting hole 131 in the second direction X. It can be understood that the side of the slot 11 facing away from the first surface 13a and towards the housing 12 is the second surface 13b. For example, the slot 11 and the second surface 13b are spaced apart (e.g.,...). Figure 4B As shown), the side of the card slot 11 opposite to the first surface 13a is the outer shell 12 or a side parallel to the outer surface of the outer shell 12.

[0102] In this embodiment, when a user uses terminal device 1, from the perspective of looking directly at the outer casing 12 (e.g., Figure 4A As shown), part of the structure of the fastener 13 covers the slot 11, and the slot 11 forms a hidden structure. Therefore, the design of the slot 11 will not destroy the integrity of the fastener 13, making the fastener 13 more intact. This is conducive to improving the flexibility and diversity of the appearance design of the terminal device 1, and making the user experience better.

[0103] In some examples, the depth of the slot 11 in the second direction X can be in the range of 0.6mm to 1mm, for example, it can be 0.7mm, 0.8mm, 0.85mm, 0.9mm, 0.92mm, etc. In this case, the slot 11 has a certain depth, allowing the movable claw 22 of the external device 2 to extend into the slot 11 (see reference...). Figure 3A and Figure 3B When the movable claw 22 and the second surface 13b of the fixing member 13 are in use, they can have sufficient overlap to ensure the reliability of the connection between the external device 2 and the terminal device 1. In addition, the depth of the slot 11 is not too deep to avoid excessive dirt accumulation in the slot 11 during the use of the terminal device 1, which also helps to reduce the difficulty of cleaning dirt and improve the user experience.

[0104] For example, on the vertical plane of the first direction Z, the first surface 13a is the main surface of the fastener 13, forming the main decorative surface of the fastener 13. The appearance shape of the fastener 13 can be designed by designing the shape of the first surface 13a. For example, the first surface 13a can be an annular surface, with no grooves or protrusions on the inner and outer annular edges. In this case, the shape of the first surface 13a has good integrity, which makes the appearance design of the fastener 13 less restricted, more flexible, and provides a better user experience for the terminal device 1.

[0105] For example, the first surface 13a can be designed as a regular ring such as a circular ring, square ring, triangular ring, or elliptical racetrack ring, or it can be designed as other irregular rings. Figure 4A In this embodiment, the first surface 13a is illustrated as an annular shape. Both the outer and inner peripheries of the first surface 13a can be complete circles without protrusions or grooves. Of course, in other embodiments, the fastener 13 can also achieve its shape design in other ways, and this application does not strictly limit this.

[0106] Understandably, the shape of the first surface 13a can correspond to that of the fixing member 13. The fixing member 13 can be designed as a circular ring, square ring, triangular ring, polygonal ring, or elliptical racetrack ring, or it can be designed as a ring of other shapes. It should be understood that the perimeter of the ring can include arc-shaped edges, straight edges, or combinations thereof, and this application does not impose any special limitations here. Figure 4A In this embodiment, the fastener 13 is illustrated as an annular shape, with the outer periphery of the fastener 13 being a complete annular ring; in Figure 4B In the illustrated embodiment, the fastener 13 is shaped like a triangular ring. The fastener 13 is roughly triangular, and the corners of the triangle are rounded to improve the safety of the user and make the fastener 13 more versatile.

[0107] In some embodiments, the protrusion 134 of the fastener 13 is located inside the first surface 13a, and in the second direction X, the width of the protrusion 134 is smaller than the width of the first surface 13a. For example, the width of the protrusion 134 may be less than one-half or one-third of the width of the first surface 13a. In this case, the shape design of the protrusion 134 can be designed to match the first surface 13a, which affects the overall appearance of the fastener 13, but the overall appearance of the fastener 13 is still mainly based on the design of the first surface 13a.

[0108] For example, the fastener 13 includes at least one protrusion 134, in Figure 4BIn the embodiment shown, the fixing member 13 includes a plurality of protrusions 134. The protrusions 134 can be circular, square, triangular, polygonal, or elliptical track rings, or they can be designed as rings of other shapes. It should be understood that the periphery of the ring can include arc-shaped edges, straight edges, or combinations thereof. This application does not impose any special restrictions here. The plurality of protrusions 134 can be evenly distributed on the first surface 13a or unevenly distributed. This application does not impose strict limitations on this.

[0109] The protrusion 134 forms a recessed groove 135, which is located on the top side of the inner side of the protrusion 133 and connects to the through hole inside the protrusion 133. The light-transmitting element 132 and the first adhesive element 136 can be located in the recessed groove 135, with the light-transmitting element 132 fixedly connected to the bottom wall of the recessed groove 135 via the first adhesive element 136. In other embodiments, the fixing element 13 and the light-transmitting element 132 can be integrally formed structural components, or the light-transmitting element 132 can be other opaque plate components.

[0110] For example, the protrusion 134 may have a positioning groove 137 on its sidewall near the first surface 13a. The external device 2 may have a structure that mates with the positioning groove 137 (see the positioning block described later). This structure can engage with the positioning groove 137 when the external device 2 is connected to the terminal device 1, so that a portion of the external device 2 remains relatively fixed to the terminal device 1. The number of positioning grooves 137 may be one or more. When there are multiple positioning grooves 137, they may be spaced apart along the circumferential direction of the fixing member 13.

[0111] In this embodiment, since the positioning groove 137 is located on the side wall of the protrusion 134, the positioning groove 137 does not damage the integrity of the first surface 13a. Therefore, it is beneficial to ensure the appearance of the fastener 13 and make the fastener 13 have better design flexibility.

[0112] In some embodiments, the fastener 13 can be a one-piece structural component to have high structural strength.

[0113] In some embodiments, the fastener 13 may be made of a metallic material to provide high strength. For example, the fastener 13 may be made of aluminum alloy, titanium alloy, etc.

[0114] In some embodiments, the slot 11 may also be formed on the fastener 13 at a position on the second surface 13b facing away from the first surface 13a. The slot 11 is formed by the fastener 13 alone and is not enclosed by the fastener 13 and the outer shell 12. The slot 11 can have high processing accuracy.

[0115] Please refer to Figure 1 to Figure 3B , Figures 16 to 18 and Figures 21A to 22B In some embodiments, the external device 2 may include a drive element 2a and a latching assembly 2b. The drive element 2a includes a drive section 21.

[0116] In some embodiments, when the terminal device 1 and the external device 2 are in a locked state, the two ends of the latching assembly 2b in the first direction Z are respectively connected to the terminal device 1 and the driving member 2a, so that the end of the driving member 2a facing away from the latching assembly 2b and the terminal device 1 in the first direction Z is located in an open environment; when performing the connection or assembly operation of the terminal device 1 and the external device 2, the user holds the driving member 2a and assembles or disassembles the external device 2 by rotating the driving member 2a. Therefore, the user can hold the driving member 2a freely, and assemble and disassemble the external device 2 more conveniently. Moreover, the shape of the driving member 2a can be flexibly set to adapt to the user's usage requirements for the driving member 2a.

[0117] In one embodiment, the drive unit 2a further includes a drive body 210, a drive part 21 and the drive body 210 are fixedly connected, and the drive body 210 is fixedly connected to the clamping member 24 through the drive part 21.

[0118] In some examples (such as) Figure 18 As shown), the driving body 210 includes a lens 2101.

[0119] In this embodiment, since the driving component 2a of the external device 2 is not limited by the size of the terminal device 1, the driving component 2a can have a larger volume. Therefore, the lens 2101 can easily have more lenses, a larger photosensitive area, a larger aperture, a longer focal length, etc. When the external device 2 is used in conjunction with the terminal device 1, the electronic system 100 has stronger shooting capabilities and better image quality.

[0120] In some other embodiments, the drive body 210 includes a cavity 2102 (e.g., Figure 27 As shown), the external device 2 is used to house functional components such as external speakers, heat sinks, power banks, communication modules, lenses, and computing chips through the cavity 2102.

[0121] In this embodiment, the position, shape and size of the external device 2 can be flexibly set as needed, so that the external device 2 can adapt to more diverse usage scenarios and provide users with a richer user experience.

[0122] It is understood that the drive unit 2a may also include more or fewer components, and the embodiments of this application do not strictly limit this.

[0123] Please see Figures 7A to 10 , Figure 7A yes Figure 1A The diagram shows the structure of the latching assembly of the electronic system. Figure 7B yes Figure 1A The second schematic diagram shows the structure of the snap-fit ​​assembly of the electronic system. Figure 8 yes Figure 7A The exploded view of the snap-fit ​​assembly shown is as follows. Figure 9A yes Figure 1A The schematic diagram of the drive unit shown is shown in Figure 1. Figure 9B yes Figure 1A The second schematic diagram shows the structure of the drive unit. Figure 10 yes Figure 8 The diagram shows the structure of the support.

[0124] In one embodiment, the latching assembly 2b includes a clamping member 24, a bracket 23, and a movable claw 22. The bracket 23 provides support for the latching assembly 2b. The clamping member 24 is fixedly connected to the driving member 2a. The bracket 23 is sandwiched between the clamping member 24 and the driving member 2a in the first direction Z, and the two sides of the bracket 23 in the first direction Z abut against the clamping member 24 and the driving member 2a, respectively. The movable claw 22 is movably connected to the bracket 23, and the driving member 2a is rotatably connected to the bracket 23. When the driving member 2a rotates relative to the bracket 23 to the first position, the movable claw 22 is located outside the slot 11, and the external device 2 and the terminal device 1 are in an unlocked state. When the driving member 2a rotates relative to the bracket 23 to the second position, at least a portion of the movable claw 22 extends into the slot 11, and the external device 2 and the terminal device 1 are in a locked state.

[0125] In some embodiments, the bracket 23 may be generally annular. The bracket 23 may have a center line 231, and the bracket 23 may be arranged around its center line 231. The bracket 23 may have multiple claw guide groups 232, which may be arranged at intervals around the center line 231 of the bracket 23. For example, the multiple claw guide groups 232 may be rotationally symmetric structures.

[0126] For example, the claw guide assembly 232 may include a first sliding groove 2321 and a second sliding groove 2322 that are spaced apart and opposite to each other, and the first sliding groove 2321 and the second sliding groove 2322 are arranged in the circumferential direction of the bracket 23. The extending direction of the first sliding groove 2321 and the extending direction of the second sliding groove 2322 are the same, and both intersect the center line 231 of the bracket 23. For example, they may be perpendicular to the center line 231 of the bracket 23, or form an angle with the center line 231 of the bracket 23 at other angles.

[0127] The claw guide assembly 232 may further include a guide post 2323, which is located between the first sliding groove 2321 and the second sliding groove 2322. The extension direction of the guide post 2323 is the same as the extension direction of the first sliding groove 2321.

[0128] In some embodiments, the guide post 2323 can be replaced by the guide groove, and the first sliding groove 2321 and the second sliding groove 2322 can be replaced by the sliding post. It should be understood that the cooperation between the guide post 2323 and the sliding groove is replaced by the cooperation between the guide groove and the sliding post.

[0129] For example, the bracket 23 includes a positioning block 233, which can be provided to protrude into the inside of the bracket 23.

[0130] Understandably, a through hole 234 is formed in the center of the bracket 23, and the positioning block 233 is located on the inner wall of the through hole 234. There can be one or more positioning blocks 233. When there are multiple positioning blocks 233, they are arranged at intervals around the center line 231 of the bracket 23.

[0131] For example, the support 23 may include a first component 23a, a second component 23b, and a third component 23c, wherein the first component 23a, the second component 23b, and the third component 23c are made of different materials and are connected as one piece. Figure 10 The diagram illustrates the first component 23a, the second component 23b, and the third component 23c using different filling patterns. The first component 23a can be the main component of the support 23, and it can form a continuous ring structure around the center line 231 of the support 23. The second component 23b can be fixed to the bottom side of the first component 23a, and it can have the aforementioned abutment surface 231b. The third component 23c can be fixed to the first component 23a near the center line 231 of the support 23, and it can include the aforementioned positioning block 233. The third component 23c can also be located on the top side of the second component 23b and connected to it.

[0132] In this embodiment, the bracket 23 includes three connected components. By designing the materials of the three components, the three components can meet the different requirements of their respective structures, thereby making the bracket 23 more versatile and its performance better.

[0133] For example, the first component 23a can be made of metal to give the bracket 23 good overall structural strength and high structural reliability. In some examples, the first component 23a can be made of aluminum alloy to give the bracket 23 good overall structural strength, light weight, and ease of processing. Alternatively, the first component 23a can also be made of metals such as aluminum, titanium, or titanium alloys. Alternatively, the first component 23a can also be made of rigid plastic materials, such as polyoxymethylene, polycarbonate, polyimide, or polytetrafluoroethylene. The material of the second component 23b can be designed according to the requirements of the abutment surface 231b, as described later. The material of the third component 23c can be designed according to the requirements of the positioning block 233, as described later.

[0134] For example, the bracket 23 has an abutment surface 231b facing the bottom side of the bracket 23. The abutment surface 231b can be an annular surface, and the abutment surface 231b is arranged around the center line 231 of the bracket 23.

[0135] Please refer to the following: Figure 11 , Figure 11 This is a schematic diagram of the structure of the clamping member 24. For example, the clamping member 24 is generally ring-shaped and is disposed on the same side of the bracket 23 in the first direction Z with the movable claw 22. It is at least partially attached to the inner surface of the first member 23a. It can be understood that the inner and outer sides of the first member 23a are both convex relative to the second member 23b. The convex portion of the inner side of the first member 23a is at least partially sandwiched between the clamping member 24 and the driving part 21, and abuts against the clamping member 24 and the driving part 21 in the first direction Z. The convex portion of the outer side of the first member 23a is at least partially connected to the movable claw 22.

[0136] Understandably, the drive unit 21 and the clamping member 24 abut against both sides of the bracket 23 in the first direction Z, that is, the drive unit 21 and the clamping member 24 apply pressure to both sides of the first member 23a in the first direction Z to fix the bracket 23. The drive unit 21 and the first member 23a, and the clamping member 24 and the first member 23a may include more components than in this embodiment to apply force to the first member 23a; this application does not impose any special limitations here.

[0137] For example, the drive unit 21 and the bracket 23 are disposed on the same side of the clamping member 24 in the first direction Z, and the drive unit 21 is fixedly connected to the clamping member 24. Among the surfaces of the clamping member 24 that do not contact the bracket 23, the drive unit 21 is fixedly connected to at least one of the surfaces.

[0138] For example, a limiting groove 213 is provided on the driving part 21. The limiting groove 213 is annular, and its size and position correspond to the clamping member 24 and the first component 23a. The two side walls of the limiting groove 213 are respectively attached to the clamping member 24 and the bracket 23. The bottom inner wall of the limiting groove 213 is also attached to both the clamping member 24 and the bracket 23. It can be understood that when the driving part 21 rotates, it drives the clamping member 24 to rotate synchronously. At the same time, the bracket 23 is limited in the first direction Z and the upper and lower directions by the clamping member 24 and the limiting groove 213 on both sides of the first component 23a, thereby fixing the position of the bracket 23. When the driving part 21 and the clamping member 24 rotate synchronously, the first component 23a and the bracket 23 located between them can remain stationary to ensure the stability of the overall structure.

[0139] Please refer to the following: Figures 2A to 3B The snap-fit ​​assembly 2b also includes a first fastener 25, which is used to fix the position of the clamping fastener 24.

[0140] In some embodiments, the clamping member 24 is fixedly connected to the driving part 21 by the first fastener 25. The clamping member 24 has a first mounting hole 241, and the first fastener 25 is connected to the driving part 21 through the first mounting hole 241. At least two first mounting holes 241 are provided on the clamping member 24. The first mounting holes 241 are evenly distributed on the inner edge of the clamping member 24 and avoid the bracket 23 in the first direction Z.

[0141] In this embodiment, the first fastener 25 is a threaded part, and the drive part 21 has a corresponding mounting hole (not shown in the figure) starting from the first mounting hole 241 to cooperate with the threaded part, so that the threaded part can stably fix the relationship between the drive part 21 and the clamping part 24, thereby enabling the drive part 21 to drive the clamping part 24 to rotate stably and synchronously when it rotates.

[0142] Understandably, the first mounting hole 241 is opened at the part where the clamping member 24 and the limiting groove 213 are connected, so that the threaded part can pass through the clamping member 24 and connect with the mounting hole on the bottom inner side wall of the limiting groove 213, making the system composed of the clamping member 24 and the drive part 21 more stable.

[0143] Please refer to the following: Figures 22A to 23B In some other embodiments, the clamping member 24 further includes a second adhesive member 244, which fixes the clamping member 24 to the driving part 21 to increase the connection strength between the clamping member 24 and the driving part 21. The second adhesive member 244 is provided at least at one location on the bottom inner wall and the inner side wall of the limiting groove 213.

[0144] Understandably, a structure for accommodating the second adhesive 244, such as an annular groove, can be selected on the surface of the clamping member 24 / inner wall of the limiting groove 213. This allows the second adhesive 244 to remain flush with the surface of the clamping member 24 / inner wall of the limiting groove 213. While fixing the clamping member 24 in the limiting groove 213 through the second adhesive 244, the contact area between the clamping member 24 and the inner wall of the limiting groove 213 can be increased, making the connection between the two tighter.

[0145] In this embodiment, the clamping member 24 has an "L" shaped cross section. That is, the clamping member 24 has a stepped structure on the outer periphery of the side facing the bracket 23 that is adapted to the shape and size of the inner edge of the first component 23a, so as to limit the bracket 23 through the concave part of the stepped structure, and further improve the stability of the first component 23a in the restricted range of movement.

[0146] It is understood that in some other embodiments, the drive unit 21 and the clamping member 24 may also adopt other fixed connection methods, and the embodiments of this application do not strictly limit this.

[0147] Please refer to the following: Figures 12A to 13B , Figure 12A yes Figure 8 The diagram shows the structure of the movable claw 22 of the latching assembly 2b. Figure 12B yes Figure 8 The diagram shows the structure of the movable claw 22 at another angle. Figure 13A yes Figure 12A The schematic diagram shows the cross-sectional structure of the movable claw 22. Figure 13B yes Figure 3C The diagram shows a cross-sectional view of the movable jaw. In some embodiments, the movable jaw 22 may include a first arm 221, a jaw 223, and a locking member 224. The first arm 221 extends in the circumferential direction, the jaw is disposed along the first direction Z, and the locking member 224 and the jaw 223 are respectively located at both ends of the first arm 221 along the first direction Z.

[0148] For example, the movable claw 22 may also include a second arm 222, the second arm 222 and the claw 223 being fixed to the first arm 221 at intervals and protruding to the same side of the first arm 221, and the locking member 224 being fixed to the side of the second arm 222 facing away from the first arm 221.

[0149] The first arm 221 can be generally plate-shaped, for example, it can be an arc-shaped plate. The second arm 222 can also be generally plate-shaped, and the thickness direction of the second arm 222 intersects with the thickness direction of the first arm 221, for example, they can be perpendicular to each other. The claw 223 can be fixed to one side of the plate surface of the first arm 221. The first arm 221 can be provided with a guide hole 2211, which can be located between the two ends of the second arm 222.

[0150] In some examples, the claw 223 has an engaging surface 2231 facing the second arm 222. The engaging surface 2231 may be inclined relative to the first arm 221; for example, the distance between the end of the engaging surface 2231 near the first arm 221 and the second arm 222 is smaller than the distance between the end of the engaging surface 2231 away from the first arm 221 and the second arm 222. In other words, the end of the engaging surface 2231 away from the first arm 221 is inclined away from the second arm 222 relative to the end of the engaging surface 2231 near the first arm 221. The locking member 224 may protrude from the plate surface of the second arm 222 away from the first arm 221.

[0151] For example, the claw 223 is a structure for engaging the terminal device 1 with the movable claw 22 (see reference). Figure 3A and Figure 3B The first arm 221 is the main structure of the movable jaw 22. The jaw 223 and part or all of the structure of the first arm 221 can be made of different materials to meet the respective structural performance requirements of the jaw 223 and the first arm 221. For example, at least part of the structure of the first arm 221 can be made of metallic materials, such as aluminum, titanium, aluminum alloy, titanium alloy, etc. In this case, the structural strength of the first arm 221 is high, which helps ensure the overall structural strength of the movable jaw 22. Alternatively, the jaw 223 can be made of rigid plastic materials, such as polyoxymethylene, polycarbonate, polyimide, polytetrafluoroethylene, etc. In this case, the wear of the jaw 223 is less when it mates with other structures, which helps ensure the reliability of the jaw 223.

[0152] Polyformaldehyde (POM) possesses excellent physical, mechanical, and chemical properties, exhibiting high hardness, high rigidity, and high wear resistance; it is commonly known as "acetal steel" or "polyacetal steel." For example, the chuck 223 can be made of POM, which offers superior wear resistance. During the relative movement of the chuck 223 and the terminal device 1, the risk of wear on the chuck 223 is reduced, thereby enhancing the reliability of the movable chuck 22. It is understood that the chuck 223 can also be made of other hard materials; this embodiment does not strictly limit its use.

[0153] For example, the claw 223 and the first arm 221 can be integrally molded structural components. In this case, the connection strength between the claw 223 and the first arm 221 is high, which helps to improve the structural reliability of the movable claw 22. For example, the claw 223 and the first arm 221 can be integrally molded using insert injection molding.

[0154] In some examples, the first arm 221 may include an arm body 221a and an insert 221b. The insert 221b is embedded in the arm body 221a, and the material of the insert 221b is different from that of the arm body 221a. A claw 223 connects to the insert 221b, and the material of the claw 223 may be the same as or different from that of the insert 221b. In this embodiment, by providing the insert 221b, which is embedded in the arm body 221a, and the claw 223 is connected to the insert 221b and made of different materials, the connection strength between the claw 223 and the first arm 221 is higher. The claw 223 and the insert 221b can be formed in the same injection molding process.

[0155] The insert 221b may include a first part 2211b, a second part 2212b, and a third part 2213b. The first part 2211b is embedded on the first side of the arm body 221a, the second part 2212b is embedded on the second side of the arm body 221a, and the third part 2213b connects the first part 2211b and the second part 2212b. The arm body 221a is made of metal, and the insert 221b is made of rigid plastic. In this embodiment, by designing the structure of the insert 221b and the mating structure between the insert 221b and the arm body 221a, the connection area between the insert 221b and the arm body 221a is larger, and the connection strength between the two is higher, thereby resulting in a higher connection strength between the claw 223 and the first arm 221.

[0156] Understandably, between the first part 2211b and the second part 2212b, the arm body 221a is spaced apart from the second part 2212b, thereby simultaneously achieving the scheme where the third part 2213b connects to the first part 2211b and the second part 2212b, and the arm body 221a is connected to the gripper 223, as shown below. Figure 13A The portion of the instantaneous arm 221a shown, which passes through the insert 221b to connect to the claw 223, is as follows: Figure 3B The diagram shows the portion where the third part 2213b connects to the first part 2211b and the second part 2212b. The third part 2213b is embedded in the arm body 221a to increase the connection strength between the insert 221b and the arm body 221a.

[0157] exist Figure 13B In the illustrated embodiment, on the radially outward side, the surfaces of the arm 221a and the second arm 222 can remain flush; Figure 13B In the embodiment shown, the surfaces of the arm 221a and the second arm 222 may have a height difference on the radially outward side, thereby increasing the radial extension range of the movable claw 22 to obtain greater activity space and degree of freedom.

[0158] For example, the second arm 222 can also be made of metal materials such as aluminum alloy or titanium alloy. Alternatively, the second arm 222 can also be made of polyoxymethylene or other rigid materials. The second arm 222 can also be an integrally formed structural component with the first arm 221.

[0159] For example, the locking component 224 can also be made of metal materials such as aluminum alloy or titanium alloy. Alternatively, the locking component 224 can also be made of polyoxymethylene or other rigid materials. The locking component 224 can also be an integrally formed structural component with the second arm 222.

[0160] Please refer to the following: Figures 14 to 17 , Figure 14 yes Figure 7A The diagram shows the structure of the bracket and the movable claw in the unlocked state. Figure 15 yes Figure 14 A cross-sectional schematic diagram of the bracket and movable jaws shown; Figure 16 yes Figure 7A The diagram shows the structure of the bracket and movable claw in the locked state. Figure 17 yes Figure 16 The diagram shows a cross-sectional view of the bracket and movable jaws.

[0161] In some embodiments, multiple movable claws 22 are mounted on and movably connected to the bracket 23. The multiple movable claws 22 are connected to multiple claw guide assemblies 232 of the bracket 23 (see also...). Figure 10 The movable claws 22 are arranged in a one-to-one correspondence. Multiple movable claws 22 are arranged at intervals along the circumference of the bracket 23. For example, the multiple movable claws 22 can be arranged at equal intervals. The claws 223 of each movable claw 22 are positioned facing the centerline 231 of the bracket 23.

[0162] For example, the movable claw 22 is slidably connected to the bracket 23, and the sliding direction of the movable claw 22 intersects the center line 231 of the bracket 23. At this time, the movable claw 22 can slide relative to the bracket 23 to move closer to or away from the center line 231 of the bracket 23. Wherein, as... Figure 14 and Figure 15 As shown, the movable claw 22 slides relative to the bracket 23 to the retracted position, and the distance between the movable claw 22 and the center line 231 of the bracket 23 is relatively large; as Figure 16 and Figure 17 As shown, the movable claw 22 slides relative to the bracket 23 to the extended position, and the distance between the movable claw 22 and the center line 231 of the bracket 23 is small.

[0163] In some examples, the sliding direction of the movable claw 22 can be perpendicular to or at an angle to the center line 231 of the bracket 23. This embodiment describes the case where the sliding direction of the movable claw 22 is perpendicular to the center line 231 of the bracket 23. When the sliding direction of the movable claw 22 is perpendicular to the center line 231 of the bracket 23, the movable claw 22 can directly extend and retract radially in the bracket 23. The movement of the movable claw 22 is simple, easy to control, and has high extension and retraction efficiency.

[0164] For example, the second arm 222 of the movable claw 22 is slidably connected to the bracket 23, and the claw 223 of the movable claw 22 moves with the second arm 222. The two ends of the second arm 222 of the movable claw 22 can be slidably connected to the first sliding groove 2321 and the second sliding groove 2322 of the bracket 23, respectively. In this case, the sliding motion of the movable claw 22 relative to the bracket 23 is more stable.

[0165] The guide post 2323 of the bracket 23 can be inserted into the guide hole 2211 of the movable claw 22. During the sliding process of the movable claw 22 relative to the bracket 23, the guide post 2323 can also guide and limit the movable claw 22 to improve the stability of the sliding action of the movable claw 22.

[0166] In this embodiment, the locking member 224 of the movable claw 22 can be exposed on the top side of the bracket 23 and protrude relative to the bracket 23. In some embodiments, the bracket 23 can be provided with a notch 239, and the locking member 224 can be inserted through the notch 239.

[0167] like Figure 9A and Figure 9B As shown, in some embodiments, the drive member 2a may have a rotation center line 211. After the drive member 2a is assembled with other structures, the drive part 21 can rotate relative to other structures around the rotation center line 211.

[0168] For example, the drive unit 21 may be provided with a plurality of guide rails 212, which are spaced apart around the rotation center line 211. For example, the plurality of guide rails 212 may be equally spaced in the circumferential direction around the rotation center line 211. The plurality of guide rails 212 may be rotationally symmetric structures.

[0169] The guide rail 212 may include a first guide rail 2121. The first guide rail 2121 has a first end 21211 and a second end 21212 opposite each other in the circumferential direction of the drive unit 21. The distance between the first end 21211 and the rotation center line 211 is greater than the distance between the second end 21212 and the rotation center line 211. In this case, the first guide rail 2121 is a variable diameter guide groove. In some examples, the distance between the first guide rail 2121 and the rotation center line 211 gradually decreases in the direction from the first end 21211 to the second end 21212. The first guide rail 2121 can be a straight groove or a curved groove; this embodiment does not strictly limit this.

[0170] Understandably, in some embodiments, the guide rail 212 can be configured as a guide groove, and correspondingly, the locking member 224 can be configured as a locking post. The locking post extends into the guide groove to realize the driving part 21 driving the movable claw 22, and can increase the stability of the sliding connection structure between the driving part 21, the movable claw 22, and the bracket 23.

[0171] In this embodiment, as Figure 3B , Figure 9B and Figure 14 As shown, the locking pins are sequentially inserted into the notch 239 and the guide groove. When the drive unit 21 rotates, it causes the locking pins to slide within the notch 239. The locking member 224 can be a cylinder.

[0172] At this time, the notch 239 is opened radially to restrict the movement path of the locking post, so that the locking post slides radially with the bracket 23 along the notch 239 during the movement, reducing the risk of dislocation of the moving claw 22.

[0173] In other embodiments, the guide rail 212 can be configured as a guide post, and correspondingly, the locking member 224 can be configured as a locking groove, with a corresponding structure on the bracket 23 that mates with the locking groove to achieve the aforementioned sliding connection. In this case, the notch 239 is configured as a guide rail corresponding to the guide post, with the path and angle being consistent with the first guide rail 2121.

[0174] This application describes an embodiment using guide rail 212 as a guide groove and locking member 224 as a locking post as an example.

[0175] The guide rail 212 may further include a second guide rail 2122, which connects to the first end 21211. The distance between the second guide rail 2122 and the rotation center line 211 remains constant in the extension direction of the second guide rail 2122. In this case, the second guide rail 2122 extends along the circumferential direction of the drive unit 21, and the second guide rail 2122 is a guide groove of equal diameter. The second guide rail 2122 smoothly transitions to the first end 21211 of the first guide rail 2121, and the distance between the second guide rail 2122 and the rotation center line 211 is equal to or similar to the distance between the first end 21211 of the first guide rail 2121 and the rotation center line 211.

[0176] The guide rail 212 may further include a third guide rail 2123, which connects to the second end 21212. The distance between the third guide rail 2123 and the rotation center line 211 remains constant in the extension direction of the third guide rail 2123. In this case, the third guide rail 2123 extends along the circumference of the drive unit 21, and the third guide rail 2123 is a guide groove of equal diameter. The third guide rail 2123 smoothly transitions to the second end 21212 of the first guide rail 2121, and the distance between the third guide rail 2123 and the rotation center line 211 is equal to or similar to the distance between the second end 21212 of the first guide rail 2121 and the rotation center line 211. The distance between the third guide rail 2123 and the rotation center line 211 is less than the distance between the second guide rail 2122 and the rotation center line 211.

[0177] In this embodiment, the first guide rail 2121 of the guide rail 212 is a variable diameter guide groove, and the second guide rail 2122 and the third guide rail 2123 are both equal diameter guide grooves, and are equal in diameter to both ends of the first guide rail 2121. Therefore, the guide rail 212 as a whole is a variable diameter guide groove.

[0178] Please refer to the following: Figure 15 and Figure 17 The locking parts 224 of the multiple movable claws 22 extend into the multiple guide rails 212 in a corresponding manner. The drive unit 21 rotates relative to the bracket 23 around the rotation center line 211, and the rotation center line 211 coincides with the center line 231 of the bracket 23.

[0179] In some embodiments, when the drive unit 21 drives the clamping member 24 to rotate, the guide rail 212 also rotates around the rotation center line 211, and slides to the notch 239 of the movable claw 22, with the sliding direction intersecting the center line 231 of the bracket 23 (that is, intersecting the rotation center line 211). Therefore, the position of the locking member 224 of the movable claw 22 changes within the guide rail 212. Since the guide rail 212 is a variable diameter guide groove, the guide rail 212 can guide the movable claw 22 to slide relative to the bracket 23, moving closer to or away from the rotation center line 211, so as to switch between the retracted position and the extended position.

[0180] For example, the drive unit 21 can rotate relative to the bracket 23 to a first position or a second position; such as Figures 14 to 15 As shown, when the drive unit 21 rotates relative to the bracket 23 to the first position, the movable pawl 22 is located at the end of the notch 239 away from the rotation center line 211. This position can be the aforementioned retracted position or a position near the retracted position; as Figures 16 to 17 As shown, when the drive unit 21 rotates to the second position relative to the bracket 23, the movable claw 22 is at one end of the notch 239 near the rotation center line 211. This position can be the aforementioned extended position or a position near the extended position.

[0181] Among them, such as Figure 14 and Figure 16 As shown, during the rotation of the drive unit 21 relative to the bracket 23 from the first position to the second position, the locking member 224 moves from the first end 21211 of the first guide rail 2121 to the second end 21212 of the first guide rail 2121. At this time, since the distance between the second end 21212 of the first guide rail 2121 and the rotation center line 211 is less than the distance between the first end 21211 of the first guide rail 2121 and the rotation center line 211, the movable claw 22 moves towards the rotation center line 211, and the movable claw 22 can switch from the retracted position to the extended position.

[0182] During the rotation of the drive unit 21 relative to the bracket 23 from the second position to the first position, the locking member 224 moves from the second end 21212 to the first end 21211. At this time, since the distance between the first end 21211 of the first guide rail 2121 and the rotation center line 211 is greater than the distance between the second end 21212 of the first guide rail 2121 and the rotation center line 211, the movable claw 22 moves away from the rotation center line 211, and the movable claw 22 can switch from the extended position to the retracted position.

[0183] When the drive unit 21 rotates relative to the bracket 23 to the first position, the locking member 224 can be located on the second guide rail 2122. When the drive unit 21 rotates relative to the bracket 23 to the second position, the locking member 224 can be located on the third guide rail 2123.

[0184] In this embodiment, since the second guide rail 2122 of the guide rail 212 has the same diameter as the first end 21211 of the first guide rail 2121, when the drive unit 21 rotates relative to the bracket 23 until the locking member 224 is at the first end 21211 of the first guide rail 2121 or the second guide rail 2122, the movable claw 22 can move to the retracted position. Since the third guide rail 2123 of the guide rail 212 has the same diameter as the second end 21212 of the first guide rail 2121, when the drive unit 21 rotates relative to the bracket 23 until the locking member 224 is at the second end 21212 of the first guide rail 2121 or the third guide rail 2123, the movable claw 22 can move to the extended position.

[0185] Therefore, the guide rail 212 can not only guide the movable claw 22 to switch between the retracted and extended positions through the variable diameter guide groove design of the first guide rail 2121, but also absorb the rotational tolerance of the drive unit 21 through the equal diameter guide groove design of the second guide rail 2122 or the third guide rail 2123, reducing the accuracy requirements of the rotational action of the drive unit 21, ensuring the full stroke displacement of the movable claw 22, and ensuring that the movable claw 22 moves into place, thereby ensuring the reliability of the movable claw 22 in unlocking and locking the terminal device 1, and also improving the user's operating experience.

[0186] Furthermore, since the second guide rail 2122 and the third guide rail 2123 are equal-diameter guide grooves, when the locking member 224 is located on the second guide rail 2122 and / or the third guide rail 2123, the degree of freedom of the movable claw 22 is jointly limited by the bracket 23 and the drive unit 21. Therefore, the position of the movable claw 22 is completely fixed, thereby ensuring the reliability of the movable claw 22 in unlocking and locking the terminal device 1.

[0187] Furthermore, since the distance between the first guide rail 2121 and the rotation center line 211 gradually decreases from the first end 21211 to the second end 21212, the movement of the movable claw 22 is smooth when switching between the extended position and the retracted position.

[0188] It is understood that, in the embodiments of this application, the extension and retraction stroke of the movable claw 22 can be designed by designing the variable diameter of the first guide rail 2121, that is, by designing the difference between the distance between the first end 21211 and the rotation center line 211 and the distance between the second end 21212 and the rotation center line 211. In other embodiments, the guide rail 212 may not include the second guide rail 2122 or the third guide rail 2123.

[0189] In some embodiments, multiple movable claws 22 are connected to the bracket 23 and the drive unit 21, and the multiple movable claws 22 move synchronously when the drive unit 21 rotates relative to the bracket 23. In this embodiment, since the multiple movable claws 22 move synchronously during the rotation of the drive unit 21 relative to the bracket 23, they can cooperate with each other to lock and unlock the terminal device 1, which helps to improve the reliability of the electronic system 100.

[0190] For example, the multiple claw guide groups 232 of the bracket 23 are rotationally symmetrical structures, the multiple movable claws 22 have the same structure, and the multiple guide rails 212 are rotationally symmetrical structures. Therefore, the multiple movable claws 22 can rotate synchronously relative to the bracket 23 in the drive unit 21.

[0191] In some embodiments, when the fastener 13 (such as Figure 4BWhen the structure is symmetrical or asymmetrical, the multiple claw guide groups 232 may not be set as rotationally symmetrical structures. Similarly, the multiple guide rails 212 may not be set as rotationally symmetrical structures. The cooperation between the two only needs to be adapted to the shape of the fixing member 13. During the movement of the claw guide group 232 driven by the guide rail 212, the movable claw 22 can cooperate with the fixing member 13.

[0192] In such Figure 1B and Figure 20B In the embodiment shown, the fixing member 13 is in the shape of a triangular ring and is not a centrally symmetrical figure. At this time, three guide rails 212 are correspondingly provided on the driving part 21, which correspond to the three sides of the triangular ring respectively. The locking members 224 on the three movable claws 22 extend into the guide rails 212 respectively to achieve sliding.

[0193] Understandable, with Figure 1B and Figure 20B Compared to the embodiments shown, Figure 1A and Figure 18 In the embodiment shown, the movable claw 22 cooperates with six centrally symmetrically distributed guide rails 212 through the locking component 224. During the unlocking and locking process, the sliding movement of the movable claw 22 along the guide rails 212 is more stable, which helps to improve the safety of the overall connection structure.

[0194] In some embodiments, the buckle assembly 2b further includes a shielding portion 29, which is annular and surrounds the outer periphery of the structure formed by the bracket 23 and the movable claw 22. The shielding portion 29 can protect the buckle assembly 2b, reduce the impact of the external environment on the movable claw 22 when the movable claw 22 is in motion, and at the same time play a role in dust prevention and improving aesthetics.

[0195] In some embodiments, the shielding part 29 is connected to the bracket 23 and remains stationary along with the bracket 23.

[0196] In one embodiment, the snap-fit ​​assembly 2b further includes a second fastener 26, which is used to fix the shielding part 29 and the bracket 23. The bracket 23 has a second mounting hole 235, and the shielding part 29 has a corresponding third mounting hole 291. The second mounting hole 235 and the third mounting hole 291 are fixedly connected by the second fastener 26, thereby fixing the shielding part 29 and the bracket 23.

[0197] For example, the inner wall of the shielding part 29 is provided with evenly distributed connecting parts 292, and the third mounting hole 291 is opened on the connecting part 292, and the third mounting hole 291 is opened along the first direction Z. Correspondingly, the second mounting hole 235 is opened along the first direction Z on the first member 23a. When assembling the shielding part 29, the first member 23a overlaps with the connecting part 292 and the second mounting hole 235 and the third mounting hole 291 are aligned so as to install the second fastener 26. Thus, after the shielding part 29 is installed, no parts or openings are exposed. The connecting structure is set inside the shielding part 29, avoiding the problem of dust accumulation and inconvenience in cleaning of the openings or parts used to achieve assembly.

[0198] Understandably, the connecting part 292 and the second mounting hole 235 are positioned to avoid the claw guide assembly 232.

[0199] In this embodiment, the second fastener 26 is a threaded part, which not only securely connects the shielding part 29 and the bracket 23, but also facilitates disassembly.

[0200] Please refer to the following: Figures 18 to 20A The assembly process of the latching assembly 2b and the drive unit 21 shown is as follows: During assembly, the movable claw 22 is first installed on the bracket 23; as shown... Figure 19 As shown, after the clamping member 24 is overlapped with the bracket 23, the clamping member 24 and the driving part 21 are fixed, thereby fixing the position of the structure composed of the bracket 23 and the movable claw 22; as shown Figure 20A As shown, the shielding part 29 is then installed on the bracket 23 to shield and protect the above-mentioned connection structure, thereby forming a stable and safe external device 2.

[0201] In some other embodiments (such as) Figures 21A to 25 As shown), the shielding part 29 is fixedly connected to the driving part 21. That is, when assembling the external device 2, the structure composed of the clamping part 24, the bracket 23 and the movable claw 22 is located in the groove formed by the shielding part 29 and the driving part 21, so that the shielding part 29 can shield the bracket 23 and the movable claw 22 and reduce the influence of the external device.

[0202] For example, the shielding part 29 is provided at the edge of the driving part 21 to adapt to the driving member 2a and provide sufficient space for the snap-fit ​​assembly 2b.

[0203] In some embodiments, the snap-fit ​​assembly 2b further includes an elastic element 27, which may be annular. Correspondingly, a receiving groove 243 is formed on the side of the clamping member 24 facing away from the driving part 21 to receive the elastic element 27. The receiving groove 243 is annular.

[0204] For example, the elastic element 27 can be a silicone element. The elastic element 27 can deform under the action of external force. It is understood that in some other embodiments, the elastic element 27 may also be made of other elastic materials and / or have other structures, which are not strictly limited in this application.

[0205] In one embodiment, the latching assembly 2b further includes a limiting member 28, which can be connected to one of the bracket 23 and the driving member 2a, and is disposed opposite to the other of the bracket 23 and the driving member 2a. When the driving member 21 rotates relative to the bracket 23 to a first position and / or a second position, the limiting member 28 is engaged with the other of the bracket 23 and the driving member 21. Specifically, the limiting member 28 is in an engaged state when the driving member 21 rotates relative to the bracket 23 to the first position and / or the second position, and is in a non-engaged state when the driving member 21 rotates relative to the bracket 23 to other positions.

[0206] In this embodiment, the external device 2 provides a limiting member 28 between the bracket 23 and the driving member 2a, and the limiting member 28 switches from a non-engaged state to an engaged state when the bracket 23 rotates to the first position and / or the second position. This not only increases the stability of the relative position between the driving part 21 and the bracket 23, thereby increasing the stability of the locking or unlocking of the movable claw 22, but also provides tactile feedback through the state change of the limiting member 28, allowing the user to easily perceive whether the driving member 2a has rotated to the correct position, thereby improving the operating feel of the electronic system 100 and providing a better user experience.

[0207] In addition, the external device 2 can also be designed with the structure of the limiting member 28 and the cooperation structure between the limiting member 28 and the driving member 2a or the bracket 23, so that the limiting member 28 emits a sound such as "ding" when the driving part 21 rotates relative to the bracket 23 to the first position and / or the second position, so as to provide acoustic feedback and further improve the user experience.

[0208] For example, the limiting member 28 is an elastic connector, and both the bracket 23 and the drive unit 21 are provided with a first recess and a second recess, which are arranged at intervals. When the drive unit 21 rotates relative to the bracket 23 to a first position, the limiting member 28 partially engages with the first recess. When the drive unit 21 rotates relative to the bracket 23 to a second position, the limiting member 28 partially engages with the second recess.

[0209] In this embodiment, by setting the limiting member 28 as an elastic connector and making the limiting member 28 engage with the recessed first and second recesses for locking, the limiting member 28 undergoes significant deformation when switching from a locked to a locked state, and collides with the groove walls of the first and second recesses, thereby providing tactile and auditory feedback and improving the user experience. Furthermore, the stable engagement structure between the limiting member 28 and the first and second recesses, made of elastic connector, helps maintain the stability of the position of the drive unit 21 in both the unlocked and locked states, thereby improving the reliability of the unlocking and locking of the external device 2.

[0210] When the walls of the first and second recesses are metal surfaces, the sound of the limiting member 28 being inserted into the first and second recesses is more obvious, which can improve the auditory feedback experience.

[0211] Understandably, the first recess and the second recess can be selectively provided on the bracket 23 or the drive unit 21, to provide feedback to the user only when the drive unit 21 rotates relative to the bracket 23 to the first position or the second position, reminding the user of the status of the external device 2 at this time.

[0212] In some embodiments, in conjunction with reference to Figure 8 , Figure 31A and Figure 31B The limiting member 28 can be a spring pin. The limiting member 28 includes a spring 281 and a pin 282, with one end of the spring 281 connected to one end of the pin 282. The end face of the pin 282 away from the spring 281 can be a spherical surface. In some examples, the end of the pin 282 away from the spring 281 can be hemispherical or other shapes including a partial spherical shape. Alternatively, the limiting member 28 can also be a spring bead. The limiting member 28 includes a spring and a bead, with one end of the spring connected to the bead.

[0213] like Figure 14 and Figure 16 As shown, the bracket 23 may be provided with a first recess 236 and a second recess 237. The openings of both the first recess 236 and the second recess 237 may be located on the side of the first member 23a near the driving part 21. The walls of both the first recess 236 and the second recess 237 may be spherical. In some examples, the shapes of the first recess 236 and the second recess 237 may be hemispherical or other shapes, including partially spherical shapes, so that the pin 282 can smoothly spring in and out of the first recess 236 and the second recess 237.

[0214] In conjunction with reference Figure 9AA third recess 214 is formed on the drive unit 21. The spring 281 of the limiting member 28 abuts against the third recess 214. When the drive unit 21 rotates relative to the bracket 23 to the first position, the pin 282 (or top ball) of the limiting member 28 is at least partially engaged in the first recess 236, and the pin 282 (or top ball) abuts against the wall of the first recess 236; Figure 30A , Figure 30B As shown, the spring 281 of the limiting member 28 abuts against the third recess 214. When the driving part 21 rotates relative to the bracket 23 to the second position, the pin 282 (or top ball) of the limiting member 28 is at least partially engaged in the second recess 237, and the pin 282 (or top ball) abuts against the wall of the second recess 237.

[0215] In order to make the spring 281 more stably supported in the third recess 214, the third recess 214 is set as a cylindrical groove, and the bottom radius matches the radius of the spring 281.

[0216] It is understood that, in the embodiments of this application, the damping of the limiting member 28 disengaging from the first recess 236 and the second recess 237 can be achieved by adjusting the spring coefficient, the depth of the first recess 236 / second recess 237, etc.

[0217] Understandably, when the limiting member 28 is located in the first recess 236 and the second recess 237, the spring 281 is in a compressed state, that is, the length of the spring 281 is less than the length of the spring 281 in its natural state. In other words, the limiting member 28 is in a compressed state in the first recess 236 and the second recess 237, thereby releasing pressure when the pin 282 is inserted into the first recess 236 or the second recess 237, striking the bottom of the first recess 236 or the second recess 237 to produce a sound, thus achieving the purpose of providing tactile and auditory feedback.

[0218] It is possible to connect. In this embodiment, the limiting member 28 is disposed between the bracket 23 and the driving member 2a as an example. Please refer to [link to relevant documentation]. Figure 24 and Figure 25 The first recess 236 and the second recess 237 are provided on the drive part 21, and the third recess 214 is provided on the bracket 23. The movement trajectory of the spring 281 and the pin 282 is the same as that in the above embodiment, and will not be described in detail here; or, the limiting member 28 and related mating structures can also be provided between the bracket 23 and the clamping member 24. The rotation of the clamping member 24 drives the rotation of the limiting member 28 and its mating with the first recess 236 or the second recess 237, which will not be described in detail here.

[0219] Please refer to it again. Figures 2A to 3BIn some embodiments, when the external device 2 is connected to the terminal device 1, the external device 2 is connected to the terminal device 1 via the drive unit 21 and the latching assembly 2b. Rotating the drive unit 21 moves the movable claw 22. When the drive unit 21 rotates relative to the bracket 23 to the first position, the movable claw 22 is in a retracted position under the combined limitation of the drive unit 21 and the bracket 23, and is located outside the slot 11. The external device 2 and the terminal device 1 are in an unlocked state. At this time, the external device 2 can be separated from the terminal device 1. When the drive unit 21 rotates relative to the bracket 23 to the second position, the movable claw 22 is in an extended position under the combined limitation of the drive unit 21 and the bracket 23, and extends into the slot 11. The external device 2 and the terminal device 1 are in a locked state. At this time, the movable claw 22 can securely lock the external device 2 onto the fixing member 13 of the terminal device 1.

[0220] For example, the latching assembly 2b is connected to the driving member 2a and the terminal device 1 on opposite sides in the first direction Z, respectively. When the user disassembles or assembles the external device 2, this is achieved by rotating the driving member 2a. When the driving member 2a rotates, the driving part 21 rotates to drive the movable claw 22 to extend out of or into the slot 11, thereby unlocking or locking the fixed member 13. One end of the driving member 2a is connected to the latching assembly 2b, and the other end is located in an open environment, allowing the user to freely hold the free end of the driving member 2a, providing a larger and more flexible gripping and support area for the user to flexibly disassemble and assemble the external device 2.

[0221] In some embodiments, the driving body 210 is located on the side of the driving part 21 in the first direction Z that is away from the clamping member 24, that is, the driving body 210 covers the light-transmitting hole 131 and the light-transmitting element 132, and the driving body 210 is fixedly connected to the driving part 21 to realize the synchronous rotation of the driving body 210 and the driving part 21.

[0222] In this embodiment, the driving body 210 is the free end of the driving component 2a. The user can drive the driving part 21 to rotate by rotating the driving body 210, making the disassembly and assembly operations simpler and more convenient.

[0223] In this embodiment, the driving body 210 may include a lens 2101 (e.g., Figure 1A , Figure 18 and Figure 20A As shown), the lens 2101, the drive unit 21, and the snap-fit ​​assembly 2b are sequentially fixedly connected to form the external device 2. It can be understood that the part of the drive unit 21 that matches the light-transmitting component 132 is also set to be a light-transmitting structure so that the lens 2101 can play its role, improve the camera performance of the terminal device 1, and enhance the user experience.

[0224] In this embodiment, the driving body 210 may also include external speakers, heat sinks, power banks, antennas and other devices, which are fixed to the terminal device 1 through the connection structure of the driving part 21 and the snap-fit ​​assembly 2b.

[0225] In this embodiment, the driving body 210 can also be a cavity 2102 (e.g., Figure 22A and Figure 27 As shown, users can place various devices in the cavity 2102, such as external speakers, heat sinks, power banks, antennas, lenses, computing chips, etc. When in use, they can be taken out directly from the cavity 2102, and after use, they can be put back into the cavity 2102 to avoid losing small, frequently used devices.

[0226] Understandably, in the cavity 2102, the drive unit 21 can also serve as the bottom surface of the cavity 2102 to reduce the weight of the drive component 2a and reduce the burden on the user when using the terminal device 1. The drive unit 21, the shielding part 29, and the cavity 2102 can be integrally molded to reduce production and assembly costs and improve the overall structural stability of the external device 2.

[0227] Please refer to the following: Figures 18 to 20B The assembly process of the latching assembly 2b and the drive unit 21 shown is as follows: During assembly, the movable claw 22 is first installed on the bracket 23; as shown... Figure 19 As shown, after the clamping member 24 is overlapped with the bracket 23, the clamping member 24 and the driving part 21 are fixed, thereby fixing the position of the structure composed of the bracket 23 and the movable claw 22; as shown Figure 20A As shown, the shielding part 29 is then fixed to the connecting bracket 23 through the second mounting hole 235 and the third mounting hole 291 to shield and protect the above-mentioned connecting structure, thereby forming a stable and safe external device 2.

[0228] In some other embodiments (such as) Figures 26 to 27 As shown), the shielding part 29 is fixedly connected to the driving part 21. That is, when assembling the external device 2, the structure composed of the clamping part 24, the bracket 23 and the movable claw 22 is located in the groove formed by the shielding part 26 and the driving part 21, so that the shielding part 29 can shield the bracket 23 and the movable claw 22 and reduce the influence of the external device.

[0229] For example, the side of the shielding portion 29 facing away from the driving portion 21 cooperates with the annular protrusion 121, close to the housing 12, or abutting against the annular protrusion 121, to improve the sealing of the connection structure between the fastener 2b and the terminal device 1, and reduce the impact of dust and other foreign objects on the connection structure. Figure 20AIn the illustrated embodiment, the fastener 13 is annular, and it is understood that the annular protrusion 121 is also annular. Correspondingly, the edge of the blocking portion 29 facing the terminal device 1 is annular and abuts against the outer periphery of 121. In the second direction X, the edge 13 of the fastener protrudes outward from the annular protrusion 121 and its abutting portion with the blocking portion 29. Therefore, the blocking portion 29 can better wrap the fastener 13 in the first direction Z, improving the safety of the buckle assembly 2b and the terminal device 1 when they work together. Figure 3D and Figure 20B In the embodiment shown, the fixing member 13 is triangular and annular. It is understood that the annular protrusion 121 is also triangular and annular. Correspondingly, the shielding part 29 needs to be fixedly connected with the driving member 2a, and its shape also needs to be set to match 2a. When the shapes of the shielding part 29 and the annular protrusion 121 are inconsistent, in order to make the shielding part 29 better match the annular protrusion 121, an extension part 293 is provided on the shielding part 29 extending in the second direction X toward one side edge of the terminal device 1. The extension part 293 abuts against the annular protrusion 121. It is understood that the outer periphery of the extension part 293 is also triangular and annular, thereby achieving better protection for the connection structure of 2b and the terminal device 1.

[0230] In some embodiments, such as Figures 21A to 25 As shown, the drive body 210 is disposed on the side of the drive part 21 facing away from the clamping fastener 24 in the second direction X, serving as an extension of the snap-fit ​​assembly 2b and the drive part 21 in the second direction X. In one embodiment, the extension direction of the drive body 210 can fit against the housing 12, wherein the drive body 210 serves as the free end of the drive member 2a, and the user can disassemble and assemble the external device 2 by rotating the drive body 210 in a plane parallel to the terminal device 1, within which the user can hold or control a larger area of ​​the drive member 2a.

[0231] Understandably, at this time, the driving body 210 does not additionally block the light-transmitting hole 131 and the light-transmitting element 132. When the external device 2 is assembled on the terminal device 1, the peripheral part of the light-transmitting element 132 is connected to the driving element 2a through the clamping fastener 24, and the other parts are exposed. The camera function on the terminal device 1 is not affected, and the user can still use the camera device on the terminal device 1 at this time.

[0232] In this embodiment, the driving body 210 may include a cavity 2102, in which users can place various devices and use the cavity 2102 as a universal adapter, such as external speakers, heat sinks, power banks, antennas, lenses, computing chips, etc. It can also store other components, which can be taken out directly from the cavity 2102 when in use and put back into the cavity 2102 after use, thus avoiding the loss of small and frequently used devices.

[0233] For example, an electrical signal interface can be provided inside the cavity 2102, which can not only accommodate various functional components, but also enable the functional components to maintain an electrical connection with the terminal device 1 inside the cavity 2102, and communicate with the terminal device 1 or supply power to the terminal device 1 through the electrical signal interface.

[0234] For example, the drive body 210 has a first electrical signal interface outside the cavity 2102 for connecting to the terminal device 1, and a second electrical signal interface inside the cavity 2102 for connecting to the functional components placed inside the cavity 2102. The first electrical signal interface and the second electrical signal interface cooperate with each other to realize the interconnection between the functional components and the terminal device 1.

[0235] In this embodiment, the drive unit 21, the shielding unit 29, and the cavity 2102 can be integrally formed to reduce production and assembly costs and improve the overall stability of the external device 2.

[0236] Understandably, in this embodiment, when assembling the external device 2, the movable claw 22 is first installed on the bracket 23 through the claw guide group 232, and then the bracket 23 is overlapped with the clamping member 24 and the clamping member 24 is fixed to the drive part 21. In this way, while the shielding part 29 shields the movable claw 22 and the outer periphery of the bracket 23, the assembly of the external device 2 is completed.

[0237] In addition, the driving body 210 may also include at least one of an external speaker, a heat sink, a power bank, or an antenna. When in use, the above devices are adapted to the terminal device 1 through the fastener 13. When not needed, they can be directly unlocked and disassembled. The working principle is the same as that of the lens 2101 mentioned above, and will not be described in detail here.

[0238] In some embodiments, a through hole 234 is provided in the center of the bracket 23. A positioning groove is provided on one of the side wall of the protrusion 134 near the first surface 13a and the inner wall of the through hole 234, and a positioning block is provided on the other. When the external device 2 is connected to the terminal device 1, the positioning groove and the positioning block cooperate to position the device, so as to improve the stability of the relative positional relationship between the bracket 23 and the fixing member 13.

[0239] For example, the length of the positioning groove along the first surface 13a is greater than the length of the positioning block, thereby providing sufficient space for the positioning block to fit and position, reducing the requirements for positioning external devices during user assembly, and making installation easier.

[0240] For example, a clearance groove is provided on the edge of the clamping member (24), the position of the clearance groove corresponds to the positioning block, and the length of the clearance groove along the circumference of the clamping member (24) is greater than the length of the positioning block, so as to achieve the purpose of clearance.

[0241] In this embodiment, as Figure 4A As shown, the fastener 13 is provided with a positioning groove 137; as Figure 10 As shown, the bracket 23 is equipped with a positioning block 233; as Figure 3B As shown, when the external device 2 is connected to the terminal device 1, the positioning block 233 is engaged in the positioning groove 137 of the fixing member 13. The positioning groove 137 can limit the positioning block 233 in the circumferential direction around the rotation center line 211.

[0242] In this embodiment, when the external device 2 is connected to the terminal device 1, the positioning block 233 and the positioning groove 137 can serve as a pre-positioning mating structure, enabling the external device 2 to accurately connect with the terminal device 1, so that the movable claw 22 can subsequently engage with the slot 11 and lock. Furthermore, after the external device 2 is connected to the terminal device 1, since the bracket 23 and the fixing member 13 are relatively fixed together by the positioning block 233 and the positioning groove 137, the user does not need to perform additional fixing operations on the bracket 23. The user can directly rotate the drive unit 21 to achieve the subsequent locking action. The user can lock the external device 2 with one hand, making operation convenient and providing a good user experience. Moreover, after the external device 2 is locked to the terminal device 1, the cooperation between the positioning block 233 and the positioning groove 137 can also increase the stability of the locking state between the external device 2 and the terminal device 1, reducing the risk of the external device 2 becoming loose, shaking, or falling off.

[0243] For example, the length of the positioning groove 137 along the first surface is greater than the length of the positioning block 233. That is, the positioning block 233 can be pre-positioned and matched with the positioning groove 137 in part. The increased length of the positioning groove 137 can provide a larger pre-positioning space for the positioning block 233. When the user pre-positions, there is a certain offset between the center of the positioning block 233 and the center of the positioning groove 137, but the positioning block 233 as a whole can still be pre-positioned within the range of the positioning groove 137. The pre-positioning will not hinder the assembly process.

[0244] For example, the third component 23c of the bracket 23, including the positioning block 233, can be made of rigid plastic material, such as polyoxymethylene, polycarbonate, polyimide, polytetrafluoroethylene, etc. In this embodiment, by setting the material of the positioning block 233, the wear of the positioning block 233 on the groove wall of the positioning groove 137 when the positioning block 233 is engaged with the positioning groove 137 can be reduced, which is beneficial to maintaining the shape of the appearance surface of the terminal device 1 and improving the service life of the terminal device 1.

[0245] For example, when assembling the clamping member 24 and the bracket 23, the clamping member 24 is assembled along the first direction Z and overlaps with the first component 23a. Therefore, a clearance groove 242 is opened on the clamping member 24. The position of the clearance groove 242 corresponds to the positioning block. The length of the clearance groove along the circumferential direction of the clamping member is greater than the length of the positioning block, thereby avoiding the clamping member 24 from conflicting with the positioning block 233 during the assembly process.

[0246] In such Figure 20B In the embodiment shown, the first component 23a has an abutment groove 231a on the inner side of the second direction X, that is, the edge of the through hole 234. It can be understood that the depth of the abutment groove 231a in the first direction Z is greater than the thickness of the pressure plate 24. After the external device 2 is connected and locked to the terminal device 1, the abutment groove 231a protrudes outward from the inner wall of the pressure plate 24 and abuts against part of the wall surface of the protrusion 134. The position of 2b is limited by this abutment relationship to improve the stability of the connection structure between the bracket 23 and the fastener 13.

[0247] Understandably, after the external device 2 is locked to the terminal device 1, the positioning block 233 is located in the positioning groove 137. Therefore, the position of the clearance groove 242 also corresponds to the positioning groove 137 and the orientation is the same.

[0248] It is understandable that in some other embodiments, a positioning block can be set on the bracket 23, and a positioning groove can be set on the fixing member 13. In this case, whether the clamping member 24 is set with a clearance groove or the clearance groove is removed, it will not affect the snap-fit ​​of the positioning block and the positioning groove.

[0249] In this embodiment, the length of the positioning groove on the fixing member 13 along the first surface 13a is greater than that of the positioning block on the bracket 23, so as to play a role in pre-positioning. The principle is the same as that in the above embodiment, and will not be repeated here.

[0250] In this embodiment of the application, after the external device 2 is connected to the terminal device 1, the external device 2 can also be electrically connected to the terminal device 1.

[0251] Please see Figure 2B , Figures 28 to 30B , Figure 28 These are exploded schematic diagrams of electronic systems in some embodiments provided in this application. Figure 29 yes Figure 28 The exploded view of the external devices and connectors shown is as follows. Figure 30A yes Figure 28 The diagram shows a cross-sectional view of the electronic system. Figure 30B yes Figure 30A A cross-sectional structural diagram of the selected portion of the electronic system shown.

[0252] For example, terminal device 1 can be provided with a first contact 139, and external device 2 can be provided with a second contact 215. After external device 2 is connected to terminal device 1, the first contact 139 and the second contact 215 make contact and form an electrical connection. External device 2 and terminal device 1 can achieve power supply and / or signal communication through the first contact 139 and the second contact 215. The signals may include control signals and / or image data. For example, after external device 2 captures an image, the image data can be transmitted to terminal device 1. Terminal device 1 can perform algorithm processing, storage, etc., on the image data, and terminal device 1 can also display the captured image on its screen.

[0253] The first contact 139 is disposed on the protrusion 133 and exposed to the fixing member 13 for connection with the corresponding interface or device; the second contact 215 is disposed on the driving part 21. The terminal device 1 also includes a connector 14, which connects the protrusion 133 and the driving part 21 to realize the electrical connection between the first contact 139 and the second contact 215.

[0254] For example, the connector 14 has a third contact 141 that mates with the first contact 139 and a fourth contact 142 that mates with the second contact 215 at both ends. A connecting hole 238 is formed at the edge of the bracket 23, and the connector 14 is located in the connecting hole 238. The third contact 141 and the fourth contact 142 are located on both sides of the bracket 23 in the first direction Z, so as to electrically connect with the corresponding contacts respectively. A connecting groove 216 is formed on the drive unit 21, and the second contact 215 is located at the bottom of the connecting groove 216. When the fourth contact 142 is electrically connected to the second contact 215, the end of the connector 14 mates with the connecting groove 216 to improve the connection strength between the second contact 215 and the fourth contact 142.

[0255] In this embodiment, the third contact 141 and the fourth contact 142 at both ends of the connector 14 have different orientations. The third contact 141 faces the second direction X, and the first contact 139 is located between the first surface 13a and the second surface 13b, so that the first contact 139 can be connected to the third contact 141. The fourth contact 142 and the second contact 215 face the first direction Z to achieve the connection between the two. At the same time, the second contact 215 is provided on the driving part 21 so that the power supply or transmission channel between the driving body 210, such as the lens 2101, and the terminal device 1 can be established through the second contact 215.

[0256] In some embodiments, the bracket 23, drive unit 21, and movable claw 22 of the external device 2 together form a rotating telescopic jaw mechanism. The external bracket 23 can be easily locked and unlocked with the terminal device 1 through the rotating telescopic jaw mechanism. Furthermore, the slot 11 of the terminal device 1 for connecting with the rotating telescopic jaw mechanism can be designed as a hidden structure, thereby achieving better appearance integrity and making the appearance design of the terminal device 1 more flexible and diverse, resulting in a better user experience.

[0257] For example, such as Figure 2A and Figure 2B As shown, when the drive unit 21 rotates relative to the bracket 23 to the first position, the projection of the movable claw 22 along the first direction Z is spaced apart from the projection of the first surface 13a along the first direction Z. At this time, the external device 2 can be smoothly inserted directly into the terminal device 1 along the first direction Z to switch from the separated state to the unlocked state; or it can be pulled directly out of the terminal device 1 along the first direction Z to switch from the unlocked state to the separated state.

[0258] For example, such as Figure 3A and Figure 3B As shown, when the drive unit 21 rotates from the first position to the second position relative to the bracket 23, the depth to which the movable claw 22 extends into the slot 11 in the second direction X can be less than the travel distance of the movable claw 22. In this way, when the drive unit 21 is in the first position relative to the bracket 23, the movable claw 22 is completely outside the slot 11, and there is a gap between it and the slot 11, ensuring smooth docking and disengagement between the external device 2 and the terminal device 1.

[0259] It should be noted that when the drive unit 21 is in the first position relative to the bracket 23, the movable claw 22 is located outside the slot 11, the movable claw 22 is not engaged with the slot 11, and the claw 223 part of the movable claw 22 does not overlap with the projection of the slot 11 in the first direction Z, so that the external device 2 can be disassembled smoothly without conflicting with the protrusion 133 in the first direction Z during disassembly. In addition, when the drive unit 21 is between the first position and the second position relative to the bracket 23, the movable claw 22 is still disengaged from the slot 11, the engaging surface 2231 and the second surface 13b have a gap, the two surfaces are not engaged or attached, and the projection of the claw 223 and the slot 11 in the first direction Z overlaps. At this time, the movable claw 22 cannot be defined as being located outside the slot 11.

[0260] The depth to which the movable claw 22 extends into the slot 11 can be represented by the overlap length between the movable claw 22 and the second surface 13b in the second direction X. For example, when the drive unit 21 is in the second position relative to the bracket 23, the depth to which the movable claw 22 extends into the slot 11 can be in the range of 0.6mm to 1mm, such as 0.7mm, 0.8mm, 0.92mm, etc. When the drive unit 21 rotates from the first position to the second position relative to the bracket 23, the travel distance of the movable claw 22 in the second direction X can be in the range of 0.9mm to 1.3mm, such as 1.0mm, 1.1mm, 1.22mm, etc.

[0261] It is understood that in this embodiment, the second surface 13b serves as a surface for engaging with the movable claw 22. The electronic system 100 can also switch between the unlocked and locked states by changing the relative position of the movable claw 22 and the second surface 13b. For example, when the drive unit 21 rotates relative to the bracket 23 to the first position, the movable claw 22 is offset from the second surface 13b and located on the side of the second surface 13b away from the center of the fixing member 13. The latching assembly 2b and the fixing member 13 are in the unlocked state, and the external device 2 and the terminal device 1 are connected. When the drive unit 21 rotates relative to the bracket 23 to the second position, the movable claw 22 abuts against the second surface 13b, and the latching assembly 2b and the fixing member 13 are in the locked state.

[0262] In some embodiments, such as Figures 2A to 3B As shown, a wedge-shaped engagement structure is formed between the second surface 13b of the fixing member 13 and the movable claw 22. Exemplarily, the second surface 13b of the fixing member 13 is inclined relative to the moving direction (e.g., the second direction X) of the movable claw 22, and / or, the engaging surface 2231 of the movable claw 22 (for engaging with the second surface 13b) is inclined relative to the moving direction (e.g., the second direction X) of the movable claw 22. In this case, the overlap area between the second surface 13b of the fixing member 13 and the movable claw 22 is large, resulting in better overlap stability, which helps ensure the reliability of the locking state between the external device 2 and the terminal device 1.

[0263] For example, such as Figure 5A and Figure 5B As shown, a limiting block 138 is provided on the second surface 13b. The limiting block 138 is set to avoid the movable claw 22. After the movable claw 22 and the second surface 13b are engaged, the limiting block 138 is distributed on both sides of the movable claw 22 along the circumference of the second surface 13b, limiting the movable claw 22 in the rotation direction of the drive unit 21, preventing the movable claw 22 from dislodging during the movement with the drive unit 21, and improving the stability of the movable claw in the unlocking state, locking state and switching process.

[0264] For example, the limiting block 138 is now symmetrically arranged within the slot 11 to provide a uniform external force to the movable claw 22.

[0265] In some embodiments, such as Figures 2A to 3B As shown, the elastic element 27 of the external device 2 is fixed to the driving element 2a and located inside the bracket 23. When the external device 2 is connected to the terminal device 1, both ends of the elastic element 27 abut against the terminal device 1 and the receiving groove 243 respectively, and are in a compressed state. For example, the elastic element 27 can abut against the periphery of the light-transmitting element 132 of the terminal device 1.

[0266] In this embodiment, since the elastic element 27 of the external device 2 abuts against the terminal device 1 and is in a compressed state, the elastic element 27 can absorb the assembly tolerance between the movable claw 22 and the fixing member 13 of the terminal device 1 in the first direction Z, so that the movable claw 22 can be stably engaged with the fixing member 13 of the terminal device 1, avoiding loosening, shaking, or falling off. The locking state between the external device 2 and the terminal device 1 is reliable.

[0267] For example, since the external device 2 elastically abuts against the terminal device 1 in the first direction Z, and a wedge-shaped engagement structure is formed between the movable claw 22 and the fixing member 13, during the process of the drive unit 21 rotating relative to the bracket 23 from the first position to the second position, the movable claw 22 can extend into the slot 11 in the second direction X without moving in the first direction Z, or the movable claw 22 can also extend into the slot 11 in the second direction X, accompanied by further compression of the elastic member 27 and movement of the movable claw 22 in the first direction Z.

[0268] For example, the end of the engaging surface 2231 of the movable claw 22 is the end of the engaging surface 2231 near the slot 11, and the end of the second surface 13b is the end of the second surface 13b near the movable claw 22. When the movable claw 22 is outside the slot 11, in the first direction Z, the end of the engaging surface 2231 is located between the end of the second surface 13b and the outer shell 12. At this time, when the drive unit 21 rotates relative to the bracket 23 from the first position to the second position, the movable claw 22 can smoothly engage into the slot 11.

[0269] When the movable claw 22 is outside the slot 11, the end of the engaging surface 2231 and the end of the second surface 13b have a first distance in the first direction Z; when the movable claw 22 extends into the slot 11, the end of the engaging surface 2231 and the end of the second surface 13b have a second distance in the first direction Z; the difference between the second distance and the first distance is less than the maximum compression of the elastic element 27. At this time, the elastic element 27 can completely absorb the assembly tolerance between the movable claw 22 and the fixing member 13 of the terminal device 1 in the first direction Z, so that the movable claw 22 smoothly engages with the fixing member 13. The maximum compression of the elastic element 27 refers to the maximum deformation that the elastic element 27 can undergo when subjected to external force.

[0270] For example, the second part 2212b includes a portion 221a extending toward the engaging surface 2231, that is, the second part 2212b extends to the surface where the claw 223 engages with the second surface 13b, so that the engaging surface 2231 is disposed on the second part 2212b. At this time, the insert 221b can be made of a hard plastic or other material, so that the engaging surface 2231 after engagement will not cause wear to the second surface 13b, and at the same time, it can provide a larger assembly tolerance for engagement, so that the claw 223 can engage more securely on the second surface 13b, thereby improving the stability of the overall engagement structure.

[0271] Understandable, Figure 4B In the embodiment shown, in order to increase the engagement area between the engagement surface 2231 and the second surface 13 and improve engagement stability, three slots 11 are provided on the triangular ring fastener 13, which are located on the three straight sides of the triangular ring and cooperate with the three movable claws 22.

[0272] In some embodiments, such as Figures 2A to 3B As shown, when the external device 2 docks with the terminal device 1, the bracket 23 remains stationary after contacting the first surface 13a. In this embodiment, the external device 2 locks and unlocks with the terminal device 1 through a rotating telescopic latch mechanism. The bracket 23 remains stationary relative to the first surface 13a of the fixing member 13 after contact during the locking and unlocking process. Therefore, the external device 2 will not cause wear to the first surface 13a due to its locking and unlocking actions, allowing the first surface 13a to maintain its good appearance. This solves the problem of poor appearance caused by latch wear on the current fixing member 13 (such as plating peeling, scratches, etc.), and the service life of the electronic system 100 is longer. In addition, the surface in the terminal device 1 that rubs against the movable claw 22 of the external device 2 is the groove wall of the slot 11 (such as the second surface 13b), and the slot 11 is a hidden structure, making the worn surface invisible and having little adverse impact on the appearance of the terminal device 1.

[0273] It should be noted that the fact that the bracket 23 remains stationary after contacting the first surface 13a can be understood not only as the two remaining completely relatively stationary, but also as basically relatively stationary, without significant relative displacement, with process tolerances and redundant design, or as having slight displacement.

[0274] For example, the bracket 23 has an abutment surface 231b for abutting against the first surface 13a, and the hardness of the abutment surface 231b is less than the hardness of the first surface 13a. In this embodiment, the electronic system 100 performs differentiated hardness design on the outer surface of the terminal device 1 and the contact surface of the external device 2, so that the hardness of the contact surface of the external device 2 is less than the hardness of the outer surface of the terminal device 1. This reduces scratches or wear on the outer surface of the terminal device 1 when the external device 2 is docked with the terminal device 1, even if the external device 2 slides relative to the outer surface of the terminal device 1. This is beneficial for maintaining the shape of the outer surface of the terminal device 1 and improving the service life of the terminal device 1.

[0275] In some examples, the hardness of the bracket 23 is less than the hardness of the fastener 13. In this case, the hardness of the abutment surface 231b on the bracket 23 is also less than the hardness of the first surface 13a of the fastener 13. For example, the bracket 23 can be made of a rigid plastic material, such as polyoxymethylene, polycarbonate, polyimide, polytetrafluoroethylene, etc. The fastener 13 can be made of a metal material, such as aluminum, copper, titanium, or related alloys. Alternatively, both the bracket 23 and the fastener 13 can be made of metal materials, but the hardness of the metal material used in the bracket 23 is less than the hardness of the metal material used in the fastener 13; for example, the bracket 23 can be made of aluminum alloy, and the fastener 13 can be made of titanium alloy.

[0276] Please combine Figure 14 In other examples, the abutment surface 231b is disposed on the second member 23b, and the hardness of the second member 23b is less than the hardness of the fastener 13. In this case, the hardness of the abutment surface 231b of the second member 23b is also less than the hardness of the first surface 13a of the fastener 13. For example, the second member 23b can be made of a rigid plastic material, such as polyoxymethylene, polycarbonate, polyimide, polytetrafluoroethylene, etc. The fastener 13 can be made of a metal material, such as aluminum, copper, titanium, or related alloys. Alternatively, both the second member 23b and the fastener 13 can be made of metal materials, where the hardness of the metal material used in the second member 23b is less than the hardness of the metal material used in the fastener 13. For example, the second member 23b can be made of aluminum alloy, and the fastener 13 can be made of titanium alloy.

[0277] It is understood that in some embodiments, the surface of the bracket 23 that directly abuts against the fixing member 13 may also include other contact surfaces. These contact surfaces may all be located in the second member 23b of the bracket 23, so as to further reduce the risk of wear on the fixing member 13 when the external device 2 docks with the terminal device 1, which is conducive to maintaining the shape of the appearance surface of the terminal device 1 and improving the service life of the terminal device 1.

[0278] Please refer to it again. Figures 1A to 1D In some embodiments, the electronic system 100 provides alignment marks on the external device 2 and the terminal device 1 for reminder purposes, thereby improving user convenience. For example, the outer surface of the drive member 2a of the external device 2 is provided with an unlock mark 31 and a lock mark 32, the outer surface of the drive member 2a is provided with a first mark 33, and the outer casing 12 is provided with a second mark 34. When the drive member 2a is docked with the terminal device 1 and the drive unit 21 is in a first position relative to the bracket 23, the first mark 33 aligns with the unlock mark 31 and the second mark 34. When the drive member 2a is docked with the terminal device 1 and the drive unit 21 is in a second position relative to the bracket 23, the first mark 33 aligns with the lock mark 32.

[0279] In this embodiment, the unlocking identifier 31 / locking identifier 32, the first identifier 33, and the second identifier 34 form a three-segment alignment identifier. By setting the three-segment alignment identifier, the electronic system 100 can improve the user's operational convenience.

[0280] For example, during the locking process between the external device 2 and the terminal device 1: Figure 1A , Figure 1C , Figure 2A and Figure 2B As shown, the first identifier 33 can be aligned with the unlock identifier 31 on the drive unit 2a first, and then the first identifier 33 can be aligned with the second identifier 34. The external device 2 is then inserted into the terminal device 1. When the first identifier 33 is aligned with the unlock identifier 31, the drive unit 21 is in the first position relative to the bracket 23, the movable claw 22 is in the retracted position, and the movable claw 22 is located outside the slot 11. Figure 1C , Figure 1D , Figure 3A and Figure 3B As shown, the drive unit 21 is then rotated so that the first mark 33 aligns with the locking mark 32 on the drive member 2a. At this time, the drive unit 21 is in the second position relative to the bracket 23, the movable claw 22 is in the extended position, the movable claw 22 is engaged in the slot 11 of the terminal device 1, and the external device 2 is locked with the terminal device 1.

[0281] It should be noted that, in contrast to the aforementioned mating structure between the positioning groove and the positioning block, when there is a certain error in the alignment process of the first mark 33 and the second mark 34, and this error is less than or equal to the length difference between the positioning groove and the positioning block along the first surface 13a, the driving component 2a can still achieve locking between the external device 2 and the terminal device 1. At this time, the length of the positioning block along the first surface 13a is still within the range of the positioning groove. Therefore, the positioning block will not conflict with the positioning groove during the locking process, thereby reducing the requirement for alignment accuracy when assembling the external device 1 and making assembly easier.

[0282] In this embodiment, a 2° redundancy is provided between the first identifier 33 and the second identifier 34. When the first identifier 33 is offset upward by less than 2° relative to the second identifier 34 around the drive unit 21, it will not affect the locking of the external device 2 and the terminal device 1.

[0283] This application also provides a subject matter, which includes, as in, Figures 7A to 17 The adapter assembly for the drive member 2a and the latching assembly 2b shown includes a clamping member 24, a bracket 23, and a movable claw 22. The clamping member 24 is fixedly connected to the drive member 2a. The bracket 23 is clamped between the clamping member 24 and the drive member 2a in the first direction Z, and the two sides of the bracket 23 in the first direction Z abut against the clamping member 24 and the drive member 2a respectively. The movable claw 22 is movably connected to the bracket 23, and the drive member 2a is rotatably connected to the bracket 23. When the drive member 2a rotates relative to the bracket 23 to the first position, the adapter assembly is in the unlocked position, and there is a first distance between the movable claw 22 and the rotation center line 211 of the drive member 2a. When the drive member 2a rotates relative to the bracket 23 to the second position, the adapter assembly is in the locked position, and there is a second distance between the movable claw 22 and the rotation center line 211 of the drive member 2a. The first distance is greater than the second distance.

[0284] Understandably, in the adapter assembly, the drive component 2a and the snap-fit ​​component 2b are connected to form an independent device so that they can be flexibly assembled with the corresponding device.

[0285] like Figure 2A and Figure 2B As shown, the adapter component is in the unlocked position, and the aforementioned drive component 2a rotates to the first position relative to the bracket 23. The external device 2 and the terminal device 1 are in the unlocked state. At this time, there is a first distance d1 between the movable claw 22 and the rotation center line 211.

[0286] like Figure 3A and Figure 3B As shown, the adapter is in the locked position, corresponding to the aforementioned drive component 2a rotating relative to the bracket 23 to the second position, the external device 2 and the terminal device 1 are in the locked state, at this time there is a second distance d2 between the movable claw 22 and the rotation center line 211.

[0287] It is understandable that the first distance d1 is greater than the second distance d2.

[0290] Understandably, different external functional components often correspond to different external connection methods, such as magnetic attraction, electrical connection via charging port, and external structure snap-fit. Therefore, a drive body 210 and a drive unit 21 are set up respectively. The drive unit 21 is used to connect with the corresponding device, and a universal connection structure can be set on the drive unit 21. This allows for flexible configuration of various drive bodies 210 to cooperate with the corresponding device by connecting to the drive unit 21. For example, an external lens can be set up to cover the lens of the corresponding device, or an external power supply can be set up to avoid the lens, etc., to meet different user needs.

[0291] For example, the driving unit 210 includes at least one of a lens 2101, an external speaker, a heat sink, a power bank, or an antenna; or the driving unit 210 includes a cavity 2102, within which an electrical signal interface is provided. It is understood that functional components such as the lens 2101, external speaker, heat sink, power bank, or antenna, after being connected to the driving unit 21, can work in conjunction with the terminal device 1. Furthermore, these functional components can also be housed within the cavity 2102, working in conjunction with the terminal device 1 via the electrical signal interface, thereby improving the versatility of the driving unit 210.

[0292] Furthermore, the other specific structures of the external device 2 can be found in the relevant descriptions above, and will not be repeated here.

[0293] This application also provides a subject matter, which includes, as in, Figures 4A to 6B The fastener 13 shown and as Figures 7A to 17The connecting device of the adapter assembly shown has a protrusion 133 of the fixing member 13 in the second direction X having a first surface 13a and a second surface 13b arranged opposite to each other.

The adapter assembly includes a driving member 2a and a latching assembly 2b. The latching assembly 2b includes a clamping member 24, a bracket 23, and a movable claw 22. The clamping member 24 is fixedly connected to the driving member 2a. The bracket 23 clamps the adapter in the first direction Z. Between the clamping member 24 and the driving member 2a, the bracket 23 abuts against the clamping member 24 and the driving member 2a on both sides in the first direction Z respectively; the movable claw 22 is movably connected to the bracket 23, and the driving member 2a is rotatably connected to the bracket 23; when the driving member 2a rotates relative to the bracket 23 to the first position, the movable claw 22 is located outside the slot 11, and the adapter is in the unlocked position; when the driving member 2a rotates relative to the bracket 23 to the second position, at least a part of the movable claw 22 extends into the slot 11, and the adapter is in the locked position.
