DETAILED DESCRIPTION

[0040] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood, and so that the scope of the present disclosure can be completely conveyed to those skilled in the art.

[0041] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should be understood as the common meanings understood by those skilled in the art to which the present application belongs.

[0042] As Figures 1 to 6 indicated, the present application provides an electronic device, comprising:

[0043] a case 1 having an electrical connection end 11;

[0044] an expansion assembly 2 having a containing space 21 and an electrical docking end 22 matching the electrical connection end 11; the expansion assembly 2 is used to expand the function of the case 1;

[0045] wherein the case 1 and the expansion assembly 2 are detachably connected, and the electrical connection end 11 and the electrical docking end 22 are electrically connected when the case 1 is located in the containing space 21.

[0046] Specifically, the case 1 can be selected as a small case 1 to save space and reduce manufacturing cost. The shape of the case 1 can be selected as a cuboid, a cylinder or other shapes, etc. When the shape of the case 1 is selected as a cuboid,

[0047] The size of the case 1 can be selected as 128mm*125mm*27mm, or can be appropriately adjusted to meet the actual use requirements. The case 1 can be configured with one or more electrical connection ends 11. When the case 1 is configured with multiple electrical connection ends 11, the number of electrical connection ends 11 can be two, three, four or even more, and the types of the multiple electrical connection ends 11 can be different to meet different expansion and connection requirements; the multiple electrical connection ends 11 can be located on different sides of the case 1; for example, the multiple electrical connection ends 11 can be respectively arranged on two first sides of the case 1 along the length direction thereof; or the multiple electrical connection ends 11 can be respectively arranged on two second sides of the case 1 along the width direction thereof; or the multiple electrical connection ends 11 can be respectively arranged on multiple adjacent sides of the case 1, and the like, to adapt to more application scenarios and meet different space layout requirements, thereby improving the adaptability. The expansion assembly 2 is used to expand the function of the case 1, for example, can be used to expand one or more functions of the case 1 such as computing, storage or graphics processing, to enhance the flexibility and adaptability of the electronic device. The electrical connection end 22 of the expansion assembly 2 is located in the accommodation space 21, thereby improving the space utilization. The case 1 can be detachably connected with the electrical connection end 22 of the expansion assembly 2 through the electrical connection end 11, so that the user can not use the expansion assembly 2 or flexibly select the expansion assembly 2 with different functions according to different application scenarios, thereby having higher adaptability.

[0048] The electrical connection end 11 and the electrical connection end 22 can be selected as a female seat and a plug matched with each other, for example, the electrical connection end 11 can be selected as a USB Type-C (Universal Serial Bus Type-C) female seat, and at this time the electrical connection end 22 can be selected as a USB Type-C plug, or vice versa; or the electrical connection end 11 can be selected as an HDMI (High-Definition Multimedia Interface) female seat, and at this time the electrical connection end 22 can be selected as an HDMI plug, and the like. The electrical connection end 11 and the electrical connection end 22 can be selected as connectors that are magnetically attracted to each other. Through the magnetic attraction force, automatic alignment and adsorption are realized, and stable and reliable electrical connection is realized, and the like.

[0049] The electronic device provided in the application has the case 1 arranged in the accommodation space 21 of the expansion assembly 2, thereby improving the integration of the system, optimizing the space management, and improving the portability; the case 1 is electrically connected with the electrical connection end 22 of the expansion assembly 2 through the electrical connection end 11, thereby realizing the expansion of the function of the case 1 by the expansion assembly 2, and since the case 1 and the expansion assembly 2 are detachably connected, the user can flexibly select the expansion assembly 2 according to different use scenarios, thereby having higher adaptability.

[0050] As Figure 3As shown, in some embodiments, the expansion component 2 has a constraint channel for guiding the chassis 1 into the accommodating space 21 so that the electrical connection terminal 11 is aligned with the electrical connection terminal 22.

[0051] Specifically, the outer surface of the chassis 1 can be configured with a protrusion, and the expansion component 2 is configured with a slide groove. The slide groove extends from the outside of the accommodating space 21 to the inside of the accommodating space 21. The protrusion can be slidably connected to the expansion component 2 through the slide groove. The slide groove is used to guide the chassis 1 into the accommodating space 21 and constrain the movement path of the chassis 1. The slide groove forms a constraint channel.

[0052] By providing a stable motion path through the constraint channel, the chassis 1 is guided into the correct position, ensuring that the electrical connection terminal 11 and the electrical connection terminal 22 are aligned, thereby providing a stable and efficient electrical connection. This greatly facilitates the user's operation and reduces the difficulty and time cost of operation.

[0053] like Figure 3 As shown, in some embodiments, the expansion component 2 is configured with a plurality of spaced interfaces 23, at least one of the interfaces 23 being used for connection to a power source and at least one of the interfaces 23 being used for connection to a display.

[0054] Specifically, the interfaces 23 may include two, three, four, five, or even more. Multiple interfaces 23 can be arranged in a distributed, linear, or matrix manner. The types of interfaces 23 can be the same or different; the interfaces 23 can be one or more of the following: USB Type-C, USB Type-A (Universal Serial Bus Type-A), HDMI, Thunderbolt 3, or Thunderbolt 4. When the expansion component 2 includes multiple types of interfaces 23, the interfaces 23 of the expansion component 2 can include USB Type-C and HDMI. The expansion component 2 can be connected to a power source via a USB Type-C port that supports power delivery, and it can be connected to a monitor via HDMI, thereby achieving power input and video output functions.

[0055] By configuring multiple interfaces 23, the input / output functions and peripheral connectivity of chassis 1 are expanded, enabling chassis 1 to meet the connection needs of different devices. Users can select the appropriate interface 23 for connection according to actual usage requirements, increasing flexibility. The spaced arrangement design helps reduce cable clutter, making the connections between devices more orderly and facilitating user management and maintenance. Furthermore, the expansion component 2 can be electrically connected to chassis 1, the monitor, and the power supply respectively. This integrated power supply method reduces the complexity of connection and setup for users, improving ease of use.

[0056] As shown in Figure 3 some embodiments, the expansion assembly 2 comprises:

[0057] a base 24 having a plurality of the interfaces 23;

[0058] two side plates 25 spaced apart and opposite to each other on the base 24, the two side plates 25 forming the constraint channel;

[0059] a connecting member 26 connecting the base 24 and the two side plates 25, the connecting member 26 having the electrical interface 22; the base 24, the two side plates 25 and the connecting member 26 collectively forming the accommodation space 21.

[0060] Specifically, the base 24 is configured to support and fix the plurality of interfaces 23. The base 24 can have a horizontal support surface, which can abut against a support surface (e.g. a desktop or a workbench, etc.) to ensure that the expansion assembly 2 is stably placed. The base 24 can have a connecting surface opposite to the support surface, which can be provided with a first clamping groove, and the side plates 25 can be clamped to the base 24 through the first clamping groove to facilitate assembly and disassembly; alternatively, the base 24 and the two side plates 25 can be integrally formed by an injection molding process or a die casting process to enhance the stability of the overall structure. The case 1 can slideably contact the two side plates 25 during entry into the accommodation space 21 to constrain the movement path of the case 1.

[0061] When the case 1 is a cuboid, the two side plates 25 can be spaced apart and opposite to each other along the length direction, the width direction or the thickness direction of the case 1. Since the thickness dimension of the miniaturized case 1 is small, when the two side plates 25 are spaced apart and opposite to each other along the thickness direction of the case 1, the space occupied by the expansion assembly 2 can be minimized.

[0062] The connecting member 26 is configured to provide the electrical interface 22. The connecting member 26 can be in the form of a plate or a block, etc. The connecting member 26 can be located within the constraint channel to make the overall appearance more concise; alternatively, the connecting member 26 can be located outside the constraint channel to facilitate maintenance. The connecting surface can be provided with a second clamping groove, and the connecting member 26 can be clamped to the base 24 through the second clamping groove to facilitate assembly and disassembly; alternatively, the base 24 and the connecting member 26 can be integrally formed by an injection molding process or a die casting process to enhance the stability of the overall structure. The connecting member 26 can be spaced apart from at least one of the side plates 25; alternatively, the connecting member 26 can be welded or integrally formed with the two side plates 25.

[0063] When the electrical connection end 22 is electrically connected with the electrical connection end 11, the case 1 can be partially located in the accommodation space 21, and the other part of the case 1 extends out of the accommodation space 21. During disassembly, the user can quickly disassemble the case 1 by pushing the extended part of the case 1 out along the path into the case 1, which is more convenient to operate and is more conducive to heat dissipation of the case 1.

[0064] As shown in Figure 3 In some embodiments, the expansion assembly 2 further comprises:

[0065] Two support wings 27 are respectively connected with two sides of the base 24 along the first direction, so that the two support wings 27 abut against the bearing surface.

[0066] Specifically, the first direction can be the length direction, the width direction, the thickness direction or other directions of the case 1. Since the thickness dimension of the miniaturized case 1 is small, when the first direction is the thickness direction of the case 1, the space occupied by the expansion assembly 2 can be minimized.

[0067] The support wing 27 can be a flat plate or an arc-shaped plate with curvature. The support wing 27 can be connected with the base 24 by bolting or welding; or the support wing 27 can be integrally formed by injection molding process or die casting process to enhance the stability of the overall structure. The expansion assembly 2 can abut against the bearing surface only by the two support wings 27, which can minimize the space occupied by the expansion assembly 2 on the bearing surface while ensuring stability, and at the same time, the air can flow through to improve the heat dissipation effect; or the support surface of the base 24 and the two support wings 27 can jointly abut against the bearing surface to ensure the stability of the expansion assembly 2.

[0068] As shown in Figure 4 and Figure 5 In some embodiments, the expansion assembly 2 has a mechanical connection end 28, a support part 29 and a bearing end 210; the support part 29 is arranged between the mechanical connection end 28 and the bearing end 210, the support part 29 has the accommodation space 21, and the accommodation space 21 forms the constraint channel; the bearing end 210 is used to abut against the bearing surface, and the mechanical connection end 28 is used to connect with the display.

[0069] Specifically, the mechanical connection end 28 can realize the physical connection and fixation of the display. The mechanical connection end 28 can be configured with a threaded hole for threaded connection with the frame of the display; or the mechanical connection end 28 can be configured with a groove for shape adaptation with the display, the groove being used for clamping the frame of the display to ensure that the user's field of view is not affected; or the mechanical connection end 28 can be configured with a clamp for clamping the frame of the display to adapt to display frames of different widths and shapes while ensuring that the user's field of view is not affected; or the mechanical connection end 28 can also adopt other forms.

[0070] The support part 29 can include a first support 291 and a first fixing part 292. The first support 291 can be connected with the mechanical connection end 28 by bolting or one-piece forming, etc. The first support 291 can have a through hole penetrating therethrough, and the first fixing part 292 is located at the through hole. The first fixing part 292 can be welded or one-piece formed with the first support 291, and the first fixing part 292 is configured with the electrical connection end 22, which is located in the through hole. The through hole forms a containing space 21, and the cabinet 1 can be embedded in the containing space 21 as a whole to improve the space utilization. Alternatively,

[0071] The support part 29 can include a second support 293, a second fixing part 294, a support part 295, and a limiting part 296. The second support 293 can be connected with the mechanical connection end 28 by bolting or one-piece forming, etc. The second fixing part 294 can be welded or one-piece formed with the second support 293, and the second fixing part 294 is configured with the electrical connection end 22. The support part 295 and the fixing part can be arranged at intervals, and the support part 295 is used to support the cabinet 1. The limiting part 296 is opposite to the support, and the limiting part 296 can be bolted or welded with the second fixing part 294, etc. Alternatively, the limiting part 296 can be welded or one-piece formed with the support part 295, etc. Alternatively, the limiting part 296 can be connected with the second fixing part 294 and the support part 295 respectively. The second support 293, the second fixing part 294, the support part 295, and the limiting part 296 jointly form the containing space 21. The support part 29 as a whole can be made of metal or high-strength plastic.

[0072] The bearing end 210 is used for stable support, and the bearing end 210 needs to have a certain weight to ensure the stability of the expansion assembly 2 and the display. The bearing end 210 can be connected with the support part 29 by bolting or one-piece forming. The bearing end 210 can include a bearing plate, and the bearing end 210 can be used to be parallel to the bearing surface to provide large-area contact and ensure stable support. Alternatively, the bearing end 210 can include three bearing columns arranged in a triangular shape. By using the stability principle of the triangular shape, a firm support effect is provided.

[0073] The mechanical connection end 28, the support part 29 and the bearing end 210 are arranged, which increases the function of supporting the display, enhances the physical stability of the display and optimizes the space utilization.

[0074] The display can be connected with the case 1 through a wire such as a USB Type-C wire or an HDMI wire. Alternatively, in some embodiments, the mechanical connection end 28 is electrically connected with the electrical connection end 22, and the display is electrically connected with the mechanical connection end 28 in the case where the display is connected with the mechanical connection end 28.

[0075] Specifically, a wiring hole can be arranged inside the expansion assembly 2, and the mechanical connection end 28 and the electrical connection end 22 can be electrically connected through a cable, and the cable passes through the wiring hole.

[0076] When the mechanical connection end 28 is a groove, a magnetic connector can be arranged in the groove, and the display can be provided with a metal contact or a magnetic interface 23 matched therewith. When the display is clamped with the groove, the magnetic connector automatically attracts and fixes the display, realizes good electrical contact, and is convenient to disassemble and install.

[0077] Alternatively, when the mechanical connection end 28 is a clamp, the clamping surface of the clamp can be provided with a USB Type-C female seat, and the display can be provided with a USB Type-C plug matched therewith. During clamping, the USB Type-C plug is inserted into the female seat to realize electrical connection, which not only provides stable physical fixation, but also ensures reliable power transmission and data communication.

[0078] Since the display and the mechanical connection end 28 can be mechanically connected and electrically connected at the same time, the number of external cables is significantly reduced, and the application environment is more tidy and orderly.

[0079] As shown in FIGS. Figure 6 and Figure 7 In some embodiments, the expansion assembly 2 comprises:

[0080] a display module 211;

[0081] a first adapter 212, which is provided with a first mounting end 2121 arranged along a first direction and the electrical connection end 22; the first mounting end 2121 is respectively electrically connected with the display module 211 and the electrical connection end 22, and the display module 211 and the first adapter 212 jointly enclose the accommodation space 21.

[0082] Specifically, the display module 211 is used to display images and video content, and expands the display function of the case 1. The display module 211 can be an AI intelligent display screen. The screen of the AI intelligent display screen can be a small round screen that can rotate 360°. The user can flexibly rotate the screen according to needs to adapt to different conversation angles and use scenarios, and meet the needs of AI application scenarios. Alternatively, the display module 211 can be a flat panel display screen or other type of display screen.

[0083] The first adapter 212 is used to realize electrical connection of the display module 211 and the case 1. The first adapter 212 can be in the form of a strip. The expansion assembly 2 can further include a cable. The first adapter 212 is configured with a wiring hole. A first end of the cable can be electrically connected with the electrical interface 22. A second end of the cable can be welded with a circuit board or an interface 23 of the display module 211 and extend out of the first adapter 212. The second end of the cable forms a first mounting end 2121. The first adapter 212 can be welded or bolted with a shell of the display module 211 to ensure the stability of the connection between the first adapter 212 and the display module.

[0084] In some embodiments, the first mounting end 2121 is rotationally connected with the display module 211. The display module 211 is configured with a first accommodating space 2111. The electrical interface 22 can be accommodated in the first accommodating space 2111 through rotation of the first mounting end 2121.

[0085] Specifically, the first mounting end 2121 can be a cylindrical plug. The display module 211 can be configured with a female seat that is adapted to the shape of the first mounting end 2121. Alternatively, the first mounting end 2121 can be a spherical joint. The display module 211 can be configured with a female seat that is adapted to the shape of the first mounting end 2121 to provide greater flexibility.

[0086] By designing the electrical interface 22 to be rotatable into the first accommodating space 2111 inside the display module 211, when the display module 211 does not need to be connected with external equipment, the user can easily rotate and store the electrical interface 22 into the first accommodating space 2111, without affecting the separate use of the display module 211, and keeping the display module 211 neat and beautiful when used alone. Alternatively,

[0087] The first mounting end 2121 is detachably electrically connected with the display module 211.

[0088] Specifically, the first mounting end 2121 can be detachably electrically connected with the display module 211 through a magnetic attraction type connector that cooperates with each other. Alternatively, the first mounting end 2121 can be detachably electrically connected with the display module 211 through a plug and a female seat that cooperate with each other.

[0089] The first mounting end 2121 is designed to be detachably connected with the display module 211. When the display module 211 does not need to be connected with the external device, the user can easily detach the first mounting end 2121 from the display module 211, which does not affect the separate use of the display module 211 and keeps the display module 211 neat and beautiful when used alone.

[0093] The second adapter 214 is arranged along the first direction and includes a second mounting end 2141 and the second sub-electrical interface 22. The second mounting end 2141 is electrically connected with the functional module 213 and the second sub-electrical interface 22, respectively. The display module 211, the functional module 213, the first adapter 212, and the second adapter 214 jointly form the accommodation space 21.

[0094] Specifically, the second mounting end 2141 is rotationally connected with the functional module 213. The functional module 213 is arranged with a second accommodation space 2131, and the second mounting end 2141 is rotationally arranged to accommodate the second sub-electrical interface 22 in the second accommodation space 2131. The specific structure of the second adapter 214 can refer to that of the first adapter 212, and the connection mode of the second mounting end 2141 with the functional module 213 can refer to that of the first mounting end 2121 with the display module 211. Alternatively, the second mounting end 2141 is detachably electrically connected with the functional module 213, and the specific connection mode can refer to that of the first mounting end 2121 with the display module 211.
