[0055] Please see Figures 1-2 , Figure 1 This is a schematic diagram of the structure of the expansion frame provided in this application. Figure 2 for Figure 1 The diagram shows the structure of the connector. This application provides an expansion frame 100, applied to electronic devices, such as mobile phones, cameras, and tablets. The expansion frame 100 includes a frame 10, a handle 20, and a connector 30. The handle 20 is rotatable relative to the frame 10. The connector 30 includes a first connector 31 and a second connector 32 connected to each other. The first connector 31 is connected to the handle 20, and the second connector 32 is connected to the frame 10. The first connector 31 has at least one first locking structure 311, and the second connector 32 has at least one corresponding second locking structure 321. Each first locking structure 311 can engage with each second locking structure 321 to fix the rotation angle of the handle 20. It can be understood that when the handle 20 rotates relative to the frame 10, and the first locking structure 311 engages with the second locking structure 321, the rotation position of the handle 20 can be fixed, allowing the user to easily and quickly fix the adjustment angle of the handle 20 for shooting at a fixed angle, reducing the difficulty of shooting and improving the shooting experience.

[0056] Please refer to Figures 3-5 , Figure 3 for Figure 2 The diagram shows the structure of the first connector. Figure 4 for Figure 2 The diagram shows the structure of the second connector. Figure 5for Figure 2 An exploded view of the second connector is shown. In some embodiments, the first connector 31 is axially connected to the second connector 32. The first snap-fit ​​structure 311 is a protrusion. The first connector 31 includes a first body 310. The protrusion protrudes from the first body 310 on the side facing the second connector 32. The second snap-fit ​​structure 321 is a slot. The second connector 32 is provided with a plurality of slots at intervals. The slots are opened on the side of the second connector 32 facing the first connector 31. The protrusion can snap into any of the slots to fix the rotation angle of the handle 20.

[0057] In some examples, the interval between two adjacent slots is 45°. Every time the handle 20 rotates 45°, the protrusion can engage in the corresponding slot, forming a fixed position at every 45° interval. The angle between two adjacent slots can be 30°, 60°, 90°, etc., and this application does not limit it.

[0058] In some embodiments, the second connector 32 is provided with an annular groove 322 surrounding the center of the shaft connection, the annular groove 322 communicating with a plurality of slots. The first connector 31 includes an adjusting member 312, the first body 310 is provided with a groove 3100, the adjusting member 312 is installed in the groove 3100, the adjusting member 312 includes a first button 313, an adjusting plate 314 and the protrusion, the first button 313 is connected to the adjusting plate 314 and is located outside the groove 3100, the first button 313 can push the adjusting plate 314 to move within the groove 3100 under the action of external force to drive the protrusion to move, in the first unlocked state, the protrusion is located within the annular groove 322, and in the first locked state, the protrusion is located within the slot.

[0059] Specifically, the first connecting body 31 is axially connected to the second connecting body 32 via a shaft connection structure. The adjusting member 312 is installed in the groove 3100 and can move within the groove 3100. The adjusting member 312 includes a ring body connected to the protrusion. The ring body passes through the shaft connection structure. The adjusting plate 314 has a hole. The ring body and the shaft connection structure are located in the hole. When the first button 313 is pressed by external force, the protrusion can move and be located in the annular groove 322. At this time, the protrusion can rotate circumferentially under the drive of the adjusting member 312. When the protrusion moves into the slot, the protrusion is engaged in the slot, and the rotation angle of the handle 20 can be fixed.

[0060] Please combine Figure 5 refer to Figure 6 , Figure 6 for Figure 1The diagram shows the structure of the frame. In some embodiments, the frame 10 includes a frame 110, and the second connector 32 includes a second body 320 and two protrusions 323 connected to the second body 320. The two protrusions 323 form a mounting groove 3230, and the frame 110 can be mounted in the mounting groove 3230, allowing the handle 20 to move on the frame 110. Specifically, the frame 110 has a rectangular structure and includes two long sides 12 and two short sides 11 arranged opposite each other. The mounting groove 3230 can be mounted on either the short side 11 or the long side 12, and the second connector 32 can slide along either the long side 12 or the short side 11 to change the position of the handle 20.

[0061] In some embodiments, the second connector 32 has at least one limiting block 324 on the side facing the frame 10, and the frame 110 has at least one limiting groove 111. Each limiting block 324 can be engaged with each limiting groove 111 to fix the movement distance of the handle 20 on the frame 110. It can be understood that the limiting groove 111 can be provided on the short side 11 or the long side 12, so that the second connector 32 can be fixed to the long side 12 or the short side 11.

[0062] In some embodiments, the second body 320 is provided with a receiving groove 3200, and the second connecting body 32 further includes a second button 325 and an elastic member 3252. The second button 325 is partially located in the receiving groove 3200 and partially protrudes from the receiving groove 3200. The elastic member 3252 is located in the receiving groove 3200. The second button 325 is connected to the elastic member 3252. When the second button 325 moves into the receiving groove 3200, the second button 325 compresses the elastic member 3252 and pushes the limiting block 324 to move.

[0063] In the second unlocked state, the limiting block 324 disengages from the limiting groove 111, and the second connecting body 32 can be displaced on the frame 110. In the second locked state, the limiting block 324 can be limited in the limiting groove 111 to fix the movement distance of the handle 20 on the frame 110.

[0064] Specifically, the elastic element 3252 is connected to the bottom of the second button 325. The elastic element 3252 can be a spring or a sheet, etc. This application does not limit the specific structure of the elastic element 3252. The limiting block 324 is connected to both sides of the second button 325. When the second button 325 is pressed, the elastic element 3252 is compressed, and the second button 325 can drive the limiting block 324 to move away from the limiting groove 111. The second connecting body 32 can be displaced on the frame 110.

[0065] Please continue to refer to this. Figure 5 In some embodiments, the second button 325 includes a guide portion 3251, the guide portion 3251 having a first inclined surface, and the limiting block 324 having a second inclined surface that cooperates with the first inclined surface. The button moves into the receiving groove 3200 under the application of external force, and the limiting block 324 can slide along the guide portion 3251 to limit the limiting block 324 to the limiting groove 111.

[0066] Specifically, due to the cooperation of the first and second inclined surfaces, when the second button 325 is pressed, the vertical pushing force of the second button 325 can be converted into a horizontal pushing force, allowing the button to move horizontally and be confined in the limiting groove 111. When the limiting block 324 is confined in the limiting groove 111, the frame 110 can only apply a horizontal force to the limiting block 324, but cannot push the limiting block 324 to move along the guide portion 3251. The limiting block 324 can maintain the limiting relationship with the limiting groove 111 to fix the moving position of the second connecting portion on the frame 110. Only when the second button 325 is pressed again can the limiting block 324 be reset along the guide portion 3251.

[0067] Please refer to Figure 7 , Figure 7 for Figure 1 The diagram shows a partial enlarged view of the expansion frame. In some embodiments, the first connecting body 31 includes a slider 315 and a wheel 316. The slider 315 is disposed within the groove 201 of the handle 20, and the wheel 316 is rotatably mounted on the first body 310. The wheel 316 is connected to the first body 310 by a fastener, and the wheel 316 can lock the displacement distance of the slider 315 within the groove 201. It is understood that when the fastener is not tightened, the slider 315 can move within the groove 201. By rotating the wheel 316, the fastener can be tightened to lock the displacement distance of the slider 315 within the groove 201, thereby changing the position of the handle 20 relative to the frame 10 according to the user's needs.

[0068] Please refer to Figure 8 , Figure 8 This is a schematic diagram of the structure of the expansion component provided in this application. This application also provides an expansion component 200, which includes the aforementioned expansion frame 100.

[0069] Please refer to Figures 9-10 , Figure 9 This is an assembly diagram of the expansion frame and filter section provided in this application. Figure 10 for Figure 9The exploded view of the expansion frame and filter section is shown. In some embodiments, the expansion assembly 200 includes a filter section 210, which includes a filter frame 211 and a filter 212. The filter frame 211 is mounted on the frame 10 of the expansion frame 100, and the filter 212 is magnetically attached to the filter frame 211.

[0070] Specifically, filter 212 can alter the way light enters the lens of an electronic device, thereby optimizing or specializing the shooting effect. Filter frame 211 can be mounted between the two long sides 12 of frame 110 and can move along the long sides 12. Filter 212 is magnetically attached to filter frame 211 and can move along the long side of filter frame 211, allowing users to adjust the position of filter 212 from different directions to adapt to different lens positions. The magnetic attachment method eliminates the need for alignment with sockets or clips; it automatically attaches and aligns when brought close, improving the installation efficiency of different filters 212.

[0071] Please refer to Figures 11-12 , Figure 11 for Figure 9 The enlarged schematic diagram of part A shown is shown below. Figure 12 for Figure 9 The diagram shows the structure of the filter frame. In some embodiments, the frame 10 includes a frame 110 and an assembly 14. The assembly 14 is fixed to the frame 110. The assembly 14 has a first through hole 121 and a plurality of second through holes 122. The first through hole 121 is a strip structure, and the second through holes 122 are circular structures. The plurality of second through holes 122 are respectively provided on both sides of the first through hole 121. The filter frame 211 includes a plate 2111. The plate 2111 is installed in the assembly groove 141 of the assembly 14. The plate 2111 has a first protrusion 2112 and a second protrusion 2113. The first protrusion 2112 can slide in the first through hole 121 to change the moving height of the filter frame 211 in the assembly groove 141. Each second protrusion 2113 can engage with any second through hole 122 to fix the moving height of the filter frame 211 in the assembly groove 141.

[0072] Specifically, the frame 110 includes a long side 12 disposed opposite to each other, and the mounting accessory 14 is fixed to the long side 12. To accommodate electronic devices of different thicknesses, the filter frame 211 can be raised. The plate 2111 is mounted in the mounting groove 141 of the mounting accessory 14 and can move within the mounting groove 141 to change the raised height of the filter frame 211. The second protrusion 2113 can be configured as a ball bearing; when the plate 2111 moves within the mounting groove 141, the ball bearing can engage with different second through holes 122 to fix the raised height of the filter frame 211.

[0073] Please refer to Figures 13-15, Figure 13 Exploded view of the expansion frame and expansion dock provided in this application. Figure 14 This is a front view of the expansion frame and expansion dock provided in this application. Figure 15 for Figure 14 A cross-sectional view along AA. In some embodiments, the expansion assembly 200 further includes an expansion dock 220, and the expansion frame 100 includes a third button 101 and a hook portion 102. The hook portion 102 has a slot 1021 on the outside of the expansion dock 220. In the third unlocked state, the third button 101 is located in the slot 1021, and the expansion dock 220 can be detached from the frame 10. In the third locked state, the third button 101 protrudes from the slot 1021, and the hook portion 102 hooks onto the expansion dock 220, and the expansion dock 220 is fixed to the frame 10.

[0074] The docking station 220 is a device that expands the interfaces of a device. It can expand a single interface of a device (such as USB-C or Thunderbolt) into multiple interfaces (such as HDMI, USB-A, Ethernet, and SD card slot), thereby improving the connectivity with external devices.

[0075] Specifically, the third button 101 is located on one side of the frame 10, and the slot of the hook part 102 is located outside the expansion dock 220. When the user presses the third button 101, the third button 101 is fully positioned within the slot 1021. At this time, the user pushes the expansion dock 220 towards the side of the third button 101, causing the expansion dock 220 to disengage from the hook part 102 and be detached from the frame 10. When the expansion dock 220 is hooked onto the hook part 102 and the third button 101 is reset, the expansion dock 220 is confined between the third button 101 and the hook part 102, and can be fixed to the frame 10.
