Abstract
Description
Technical Field
[0001] This application relates to the field of photographic aids, and more particularly to an extension frame and a shooting device. Background Technology
[0002] Currently, in the field of mobile photography equipment technology, mobile phone expansion frames are widely used as auxiliary shooting tools, but their design still has significant flaws. Traditional mobile phone expansion frames generally adopt a one-piece structure, which leads to many inconveniences for users in actual use. Because the entire frame is not detachable, after the expansion frame is installed on the phone, its weight is concentrated on one side of the device. Over time, this can easily cause uneven stress on the device, affecting grip stability and the shooting experience. In addition, the one-piece structure is bulky, taking up a lot of space when carried, making it difficult to adapt to different storage scenarios. If users need to temporarily remove the expansion frame to reduce the burden on the device or for storage, they often cannot quickly disassemble and reassemble it due to the fixed structure, severely limiting the flexibility of use. Especially when shooting outdoors or frequently switching usage scenarios, users are forced to compromise between portability and functionality, failing to meet the needs of efficient operation and lightweight carrying.

[0042] This application provides an expansion frame, which includes a frame 100, a fastener 200, and a snap fastener assembly 300. Specifically, the frame 100 includes multiple side frames that define an installation space 101. The fastener 200 is disposed at the connection between two adjacent side frames and is used to fix the two adjacent side frames together. The snap fastener assembly 300 is disposed at the connection between the remaining two adjacent side frames and is used to rotate and snap together the two adjacent side frames.
[0043] Please see Figure 1 and Figure 2 As shown, in order to enable the installation of a mobile phone, multiple frame connections define an installation space 101. The mobile phone is placed in the installation space 101 to achieve installation. Furthermore, in order to facilitate the disassembly and storage of the frame 100, two adjacent frame parts are fixedly connected by fasteners 200 at their close positions, while the other frame parts are detachably connected by swivel fasteners 300 at their close ends.
[0044] In some specific embodiments, the frame 100 has multiple bends and multiple straight sections, the fastener 200 is disposed at one of the bends, and the snap fastener assembly 300 is disposed at the remaining bends or at any position of the remaining straight sections; or, the fastener 200 is disposed at any position of one of the straight sections, and the snap fastener assembly 300 is disposed at the remaining bends or at any position of the remaining straight sections.
[0045] For example, when the fastener 200 is located at one of the bends and the snap fastener 300 is located at the other bends, the two adjacent frames are connected at the bends.
[0046] For example, when the fastener 200 is located at one of the bends and the snap fastener 300 is located at other straight sections, two adjacent frames are fixedly connected at the bends by the fastener 200, and the other two adjacent frames are connected at the straight sections by the snap fastener 300.
[0047] For example, when the fastener 200 is located at any position on one of the straight sections and the snap fastener 300 is located at other bent sections, two adjacent side frames are fixedly connected at any position on the straight section by the fastener 200, and other two adjacent side frames are connected at the bent sections by the snap fastener 300.
[0048] For example, when the fastener 200 is located at any position of one of the straight sections and the snap fastener assembly 300 is located at any position of the other straight sections, two adjacent frame sides are fixedly connected at the straight section positions by the fastener 200, and other two adjacent frame sides are connected at the straight section positions by the snap fastener assembly 300.
[0049] It can be understood that when the fastener 200 and the swivel assembly 300 are set on the straight part of the frame, each frame has a corner, i.e., a bend, in order to adapt to the shape of the shooting device (mobile phone). The presence of the corner increases the difficulty of storage after each frame is disassembled. Therefore, in this embodiment, the fastener 200 and the swivel assembly 300 are set at the connection between two adjacent frames, i.e., at the corner of the frame 100. The two adjacent frames can be detached and connected at the corner. That is, the fastener 200 and the swivel assembly 300 are set at the corner. After the two adjacent frames are connected, a corner is formed to adapt to the shape of the shooting device. The following will use the example of the fastener 200 and the swivel assembly 300 being set at the corner. It can be understood that the corner is formed at the connection between two adjacent frames. After disassembly, the corner disappears or the corner curvature becomes smaller, and the frame as a whole is in the shape of "I", which makes it easier to store the frame.
[0050] It should be noted that during the assembly of the mounting frame, the remaining frame edges at the location of the fastener 200 are first quickly rotated and fastened together using the snap-fit assembly 300. Finally, the fastener 200 is used to secure the two adjacent frame edges at that location, thus forming a stable frame 100. Understandably, when disassembly is required, simply release the fastener 200 from its connection to the two adjacent frame edges at that location. Then, the remaining frame edges can be disassembled simply by rotating them, achieving a quick disassembly and assembly function. This allows for the storage of each frame edge, reducing the volume occupied by the frame 100.
[0051] In some specific embodiments, the frame 100 is composed of at least four side frames connected end to end, wherein at least one pair of adjacent side frames are fixedly connected by fasteners 200, and the remaining adjacent side frames are detachably connected by swivel fasteners 300.
[0052] See Figure 1 and Figure 2As shown, in this embodiment, there are a total of four borders, which are arranged in a rectangular distribution. The frame 100 composed of the four borders is rectangular. It can be understood that the connection between two borders forms a corner, that is, the frame 100 has four corners. In this embodiment, the fastener 200 and the swivel assembly 300 are both set at the corner positions to connect adjacent borders. Specifically, the two adjacent borders at one corner are connected by the fastener 200, and the two adjacent borders at the other three corners are detachably connected by the swivel assembly 300.
[0053] In some specific embodiments, the four frames include a first frame 110, a second frame 120, a third frame 130, and a fourth frame 140, which are arranged sequentially from end to end. A first connector 111 is provided at the end of the first frame 110 facing the second frame 120, and the first connector 111 has a through hole 112 passing through it. A second connector 121 is provided at the end of the second frame 120 facing the first frame 110, and the second connector 121 has a through hole 122 passing through it. The fastener 200 passes through the through hole 112 and is connected to the through hole 122.
[0054] Please see Figure 1 and Figure 2 As shown, specifically, in this embodiment, the first frame 110 and the third frame 130 are arranged relative to each other, and the second frame 120 and the fourth frame 140 are arranged relative to each other. That is, the first frame 110, the second frame 120, the third frame 130 and the fourth frame 140 are arranged in a rectangular distribution to define an installation space 101 for installing a mobile phone.
[0055] In another embodiment, the phone can be replaced with a camera, and the shape of the camera can be adapted by changing the number, width, length, and shape of the multiple borders.
[0056] In some specific embodiments, the first frame member 110 is provided with a first connector 111 at the end facing the second frame member 120, and the first connector 111 has a through hole 112 passing through it; the second frame member 120 is provided with a second connector 121 at the end facing the first frame member 110, and the second connector 121 has a through hole 122 passing through it, and the fastener 200 passes through the through hole 112 and is connected to the through hole 122.
[0057] Please see Figure 2 , Figure 3 and Figure 5As shown, after the third frame 130 is connected to the fourth frame 140, and the fourth frame 140 and the first frame 110 are connected by the snap fastener assembly 300, during the process of connecting the second frame 120 to the third frame 130 by rotation, the second connector 121 at the other end of the second frame 120 will gradually rotate to the position of the first connector 111 of the first frame 110, until the connecting hole 122 and the through hole 112 are coaxial. At this time, the second frame 120 completes the rotational installation with the third frame 130, and then it is fixed. The component 200 is connected to the connecting hole 122 through the through hole 112, thereby connecting the first connecting component 111 and the second connecting component 121, and thus fixing the first frame component 110 and the second frame component 120. Since the positions of the first frame component 110 and the second frame component 120 are fixed, the third frame component 130 and the fourth frame component 140 cannot rotate at this time. The first frame component 110, the second frame component 120, the third frame component 130 and the fourth frame component 140 cannot be moved, thus keeping the entire frame 100 stable.
[0058] When the frame 100 needs to be disassembled, the connection between the first connector 111 and the second connector 121 is first released by the fastener 200. Next, the second frame 120 can be rotated to separate from the third frame 130. The third frame 130 is rotated to separate from the fourth frame 140. Similarly, the fourth frame 140 is rotated to separate from the first frame 110, thereby completing the disassembly of each frame for easy storage and carrying.
[0059] In some specific embodiments, the fastener 200 includes a driving part 210, and a connecting part 220 is provided on the end face of the driving part 210. The connecting part 220 passes through a through hole 112 and is connected to the connecting hole 122.
[0060] Please see Figure 2 As shown, the connecting part 220 is a threaded rod, and the driving part 210 is a handle. The driving part 210 drives the connecting part 220 to connect with the connecting hole 122, thereby fixing the first connecting member 111 and the second connecting member 121, and thus realizing the connection between the first frame member 110 and the second frame member 120. Correspondingly, in order to realize the connection, the connecting hole 122 is a threaded hole.
[0061] In some specific embodiments, in order to facilitate the rotation of the drive unit 210, the circumferential surface of the drive unit 210 is provided with anti-slip protrusions or anti-slip grooves, thereby increasing the friction and facilitating the transmission of the twisting force.
[0062] In some specific embodiments, flanges 102 are provided at the edges of the first frame 110, the second frame 120, the third frame 130 and the fourth frame 140, that is, the edge of the mobile phone can be placed on the flanges 102, thereby making it easier to limit and fix the mobile phone. Specifically, the flanges 102 are integrally provided at the bottom edges of the first frame 110, the second frame 120, the third frame 130 and the fourth frame 140.
[0063] In this embodiment, at least one of the first frame member 110, the second frame member 120, the third frame member 130 and the fourth frame member 140 is provided with a through hole 103.
[0064] In this embodiment, the size, shape and number of the clearance holes 103 provided on the first frame 110, the second frame 120, the third frame 130 and the fourth frame 140 are different. These clearance holes 103 can be used to avoid the buttons of the mobile phone, or to avoid the data cable connected to the mobile phone, etc. That is, clearance holes 103 of different shapes and numbers can be provided as needed.
[0065] In this embodiment, in order to prevent the inner sidewall of the frame 100 from causing wear and tear on the mobile phone, a protective pad can be provided on the sidewall of the first frame 110, the second frame 120, the third frame 130 and the fourth frame 140 to prevent them from directly contacting the mobile phone and causing wear and tear.
[0066] In this embodiment, in order to ensure the strength of each component, the first frame 110, the second frame 120, the third frame 130, the fourth frame 140 and the fastener 200 can all be made of metal.
[0067] In some specific embodiments, the snap fastener assembly 300 includes a limiting member 310 and a snap-fit structure 320. The limiting member 310 is disposed at one end of one of the frame sides, and the snap-fit structure 320 is disposed at the end of the frame side adjacent to the limiting member 310. The limiting member 310 is rotated and snapped into the snap-fit structure 320 to achieve a detachable connection between two adjacent frame sides.
[0068] Please see Figures 2 to 6As shown, both ends of the third frame 130 are provided with limiting members 310, and both ends of the fourth frame 140 are provided with snap-fit structures 320. Furthermore, in order to cooperate with the limiting members 310 at both ends of the third frame 130 and the snap-fit structures 320 at both ends of the fourth frame 140, a snap-fit structure 320 is provided at the end of the second frame 120 facing the third frame 130, and a limiting member 310 is provided at the end of the first frame 110 facing the fourth frame 140. This enables the second frame 120 to be connected to the third frame 130, the third frame 130 to the fourth frame 140, and the first frame 110 to the fourth frame 140 by rotating and snapping together using the limiting members 310 and the snap-fit structures 320, thereby achieving quick connection and disassembly of each frame.
[0069] In some specific embodiments, the limiting member 310 includes a boss 311 disposed on the end of the frame, the end face of the boss 311 is provided with a relief groove 312, and the peripheral surface of the boss 311 is provided with a first slot 313 and a second slot 314 in the radial direction, and the first slot 313 and the second slot 314 are both connected to the relief groove 312.
[0070] The snap-fit structure 320 includes a groove 321, which is formed at the end of the frame adjacent to the limiting member 310. A pin 322 is fixedly arranged inside the groove 321 in the radial direction.
[0071] Please see Figures 3 to 6 As shown, since the first frame 110 and the fourth frame 140, the second frame 120 and the third frame 130, and the third frame 130 and the fourth frame 140 are all detachably connected by a snap fastener assembly 300, that is, the connection and disassembly methods between adjacent parts are the same. Therefore, the second frame 120 and the third frame 130 are used as examples for illustration.
[0072] In this embodiment, a boss 311 integrally formed therewith is provided at the end of the third frame member 130 near the second frame member 120. A relief groove 312 is formed on the end face of the boss 311, and a first slot 313 and a second slot 314 communicating with the relief groove 312 are formed on the peripheral surface of the boss 311. See details. Figure 4As shown, the first slot 313 is located above the left opening of the clearance slot 312, and the second slot 314 is located below the right opening of the first slot 313. Both the first slot 313 and the second slot 314 are connected to the clearance slot 312. The first slot 313 and the second slot 314 are connected radially through the second slot 314. It can be understood that the opening of the first slot 313 faces the upper left, and the opening of the second slot 314 faces the lower right. Furthermore, in this embodiment, the boss 311 has a circular cross-section, and both the first slot 313 and the second slot 314 are quarter-circles in size. The positional relationship between the clearance slot 312, the first slot 313, and the second slot 314 can be found in the detailed reference. Figure 4 As shown.
[0073] See Figure 5 As shown, in order to enable quick assembly and disassembly of the second frame 120 and the third frame 130, a groove 321 is provided at the end of the second frame 120 facing the third frame 130. A pin 322 is fixedly installed in the groove 321 along its radial direction, so that the pin 322 passes through the clearance groove 312 and is engaged in the first slot 313 and the second slot 314 to complete the rotational engagement connection.
[0074] Specifically, when the second frame 120 and the third frame 130 need to be connected, firstly, the pin 322 is aligned with the clearance groove 312. Next, the boss 311 extends into the groove 321. As the boss 311 extends into the groove 321, the groove 321 also extends into the clearance groove 312. When the boss 311 has completely extended into the groove 321, the pin 322 is also fully inserted into the clearance groove 312, and the pin 322 is located at the opening position of the first slot 313 and the second slot 314. Then, the second frame 120 or the third frame 130 can be rotated to rotate the pin 322 into the first slot 313 and the second slot 314. As rotation continues, the pin... The shaft 322 will abut against the inner wall of the first slot 313 and the second slot 314 to reach the preset position. At this time, the second frame 120 and the third frame 130 are connected. Since the pin 322 is located in the first slot 313 and the second slot 314, if the second frame 120 or the third frame 130 is pulled along the axial direction of the boss 311, the positions of the two will remain fixed. Only by rotating the second frame 120 or the third frame 130 in the opposite direction can the pin 322 be disengaged from the position of the first slot 313 and the second slot 314 and enter the clearance groove 312. Only by moving the second frame 120 or the third frame 130 along the axial direction of the boss 311 can the two be disassembled and separated.
[0075] The connection between the third frame 130 and the fourth frame 140, and between the fourth frame 140 and the first frame 110, will not be elaborated here. Please refer to the connection method and process of the second frame 120 and the third frame 130 described above.
[0076] This application also provides a shooting device, which includes a stabilizer and an extension frame as described in any of the above claims. Specifically, the stabilizer has a mounting position, and the extension frame is mounted on the mounting position.
[0077] In this embodiment, the stabilizer can be a gimbal. The extension frame is fixedly mounted on the gimbal, thereby enabling the mobile phone or camera located in the extension frame to shoot stably and improve the shooting quality.
