[0002] Compared to regular digital cameras, action cameras offer advantages such as smaller size, stable shooting, and strong waterproof performance, greatly facilitating outdoor shooting. Another unique feature of action cameras is their ability to be placed and used anytime, anywhere, allowing athletes to be both photographers and stars, such as in underwater and water photography, skiing, cycling, and mountaineering, enjoying their activities without hindrance. This has made them popular among users. However, action cameras often present challenges in handheld use, necessitating the use of a tripod to secure them to a table or other location. Common action cameras, such as those from DJI and Inspire, feature quick-release mounts. Foldable magnetic mounts, a common type of electronic device stand, are small and offer flexible orientation adjustments. However, current foldable magnetic mounts cannot directly connect to cameras with quick-release mounts, and their adjustment range and freedom are limited, restricting the application scenarios for action cameras.

The positioning pin passes through the first snap-fit ​​block and the first pressing block. The first snap-fit ​​block extends out of the mounting surface. The elastic force provided by the first elastic element drives the first snap-fit ​​block to automatically flip and engage in the quick-release slot. The first pressing block extends out of the outer wall surface of the base. Pressing the first pressing block causes the first snap-fit ​​block to flip outward and disengage from the quick-release slot simultaneously.

[0020] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0021] Furthermore, 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] Reference Figure 1 and Figure 2 This application provides a folding magnetic bracket 1, which achieves folding storage and multi-angle support adjustment through multiple rotating connections. Figure 1 The illustration shows that when the folding magnetic bracket 1 is in a fully folded state, all the components are stacked and overlapped, making it thin, light, and small in size, which makes it easy to store and carry. Figure 2 The illustration shows the fully unfolded position of the folding magnetic stand 1. The folding magnetic stand 1 is composed of... Figure 1 Expand to Figure 2 During the process, the folding magnetic bracket 1 can present different support states depending on the degree of unfolding, the most common being the seat support state and the handle grip state; depending on the usage scenario, users can use the folding magnetic bracket 1 as a car mount, selfie stick, and outdoor support frame, etc.

[0024] Reference Figure 1-3 The folding magnetic bracket 1 includes a magnetic base 10, a folding arm 20, an adapter 30, and a quick-release clamp 40, which are rotatably connected in sequence. The magnetic base 10 is for attaching external devices with magnetic surfaces. The folding arm 20, as a connector and support, has a first end 21 and a second end 22 that are opposite each other along its axial direction. The first end 21 is rotatably connected to the magnetic base 10 via a first rotating shaft 51. The adapter 30 has a first end face 31 and a second end face 32 that are opposite each other along its thickness. The first end face 31 is rotatably connected to the second end 22 via a second rotating shaft 52. The quick-release clamp 40 includes a base 41 and two quick-release clamps 42. The base 41 is rotatably connected to the second end face 32 via a third rotating shaft 53. The base 41 has a mounting surface 411 facing away from the second end face 32. The two quick-release clamps 42 are spaced apart on opposite sides of the mounting surface 411 and can be close to or far apart from each other to allow for the attachment and removal of cameras with quick-release bayonets.

[0025] Among them, the first rotating shaft 51, the second rotating shaft 52 and the third rotating shaft 53 can be collectively referred to as the rotating assembly 50 of the folding magnetic bracket 1. The first rotating shaft 51 and the second rotating shaft 52 are parallel to each other and both are perpendicular to the axial direction of the folding arm 20. The axial direction of the third rotating shaft 53 is not limited.

[0026] The folding magnetic bracket 1 provided in this application has a quick-release clip 40 with two quick-release clips 42 that are relatively close or far apart, for mounting and dismounting cameras with quick-release mounts, and is compatible with camera products from common brands such as DJI and InSight. This application combines the folding magnetic bracket 1 with the quick-release clip, allowing users to magnetically support cameras with quick-release mounts in different usage scenarios using the folding magnetic bracket 1. Furthermore, the quick-release clip can rotate around the first pivot 51, or the second pivot 52, or the third pivot 53 to flexibly adjust the shooting angle of the action camera, thereby meeting more shooting needs of photography enthusiasts and adapting to more outdoor shooting scenarios.

[0027] Optionally, in conjunction with reference Figure 3 and Figure 4 In one embodiment, the third pivot 53 is perpendicular to the second end face 32, and the third pivot 53 is perpendicular to the first pivot 51 and the second pivot 52. During the rotation of the quick-release clamp 40 around the third pivot 53 relative to the adapter 30, it remains attached to the second end face 32, preventing unnecessary collisions between the quick-release clamp 40 and the folding arm 20 or the magnetic base 10 during rotation. Of course, in other embodiments of this application, the third pivot 53 may not be perpendicular to the first pivot 51 and the second pivot 52, as long as the base 41 is rotatably connected to the second end face 32 via the third pivot 53.

[0028] Furthermore, in conjunction with references Figure 3-5In one embodiment, one of the second end face 32 and the side of the base 41 facing away from the mounting surface 411 is provided with glass beads 33, and the other is provided with glass bead grooves 43. The ends of the glass beads 33 are elastically engaged in the glass bead grooves 43. Multiple glass beads 33 are arranged circumferentially around the third rotating shaft 53, and / or multiple glass bead grooves 43 are arranged circumferentially around the third rotating shaft 53. Here, during the rotation of the base 41 relative to the adapter 30 around the third rotating shaft 53, the glass beads 33 can rotate from one glass bead groove 43 to the next, or a glass bead groove 43 can rotatably accommodate different glass beads 33. The cooperation between the glass beads 33 and the glass bead grooves 43 not only limits the rotation angle and provides a certain rotational damping, but also improves the rotational feel. To improve the rotational damping between the adapter 30 and the base 41, a damping ring 54 is provided between the second end face 32 and the base 41, and the damping ring 54 is passed through the third rotating shaft 53. It should be understood that in other embodiments, the cooperation between the glass beads 33 and the glass bead groove 43, and the setting of the damping ring 54, can both improve rotational damping. Therefore, in one embodiment, only the glass beads 33 and the glass bead groove 43 can be set, without setting the damping ring 54; or, in one embodiment, only the damping ring 54 can be set, without setting the glass beads 33 and the glass bead groove 43; or, in one embodiment, the glass beads 33 and the glass bead groove 43, and the damping ring 54 can all be omitted, and other structures that increase rotational damping can be adopted.

[0029] Preferably, in conjunction with reference Figure 4 and Figure 6 In one embodiment, one of the second end face 32 and the side of the base 41 facing away from the mounting surface 411 is provided with an annular protrusion 34, and the other is provided with an annular groove 44. The annular protrusion 34 is aligned and engaged in the annular groove 44 along the normal direction of the second end face 32. The annular protrusion 34 can rotate around the third pivot 53 within the annular groove 44 to improve the stability of the rotational connection between the base 41 and the second end face 32. Here, the annular protrusion 34 and the annular groove 44 are respectively provided on the edges of the second end face 32 and the base 41 to further improve the rotational connection stability. It should be noted that, without considering the rotational connection stability, the presence or absence of the annular protrusion 34 and the annular groove 44 is not limited in other embodiments of this application.

[0030] Preferably, in conjunction with reference Figure 3 and Figure 4In one embodiment, one of the first end face 31 and the second end 22 is provided with a mounting block 35, and the other is provided with a lug 23. The second rotating shaft 52 passes through the mounting block 35 and the lug 23 in sequence, so that the first end face 31 is rotatably connected to the second end 22. Further, the magnetic base 10 includes a magnetic ring 11. The magnetic base 10 and the adapter base 30 can rotate relative to the folding arm 20 to abut against opposite sides of the folding arm 20. The mounting block 35 and the lug 23 are provided with the magnetic ring 11, so that the overall thickness of the folding magnetic bracket 1 is thinner and its volume is more compact, making it easier for users to carry and store. Here, combined with... Figure 2 The number of lugs 23 is two, and they are spaced apart to form a mounting groove 24. The mounting block 35 is confined within the mounting groove 24 and can rotate within the mounting groove 24 to further improve the rotational connection stability between the first end face 31 and the second end 22. Of course, in other embodiments, the number of lugs 23 can also be one. If the thickness and volume of the entire folding magnetic bracket 1 in the folded state are not considered, the magnetic base 10 and the adapter base 30 can also be folded and stored on the same side of the folding arm 20. In addition, the shape of the magnetic base 10 is not limited. The magnetic ring 11 is used to provide clearance space for the mounting block 35 and the lugs 23 so that the entire folding magnetic bracket 1 is thinner and lighter. In other embodiments, the magnetic base 10 can also be a magnetic block or other shapes.

[0031] Furthermore, in conjunction with references Figure 4 and Figure 7 In one embodiment, the magnetic base 10 has a first threaded interface 12 on its edge, spaced apart from the magnetic ring 11; and / or, the mounting block 35 has a second threaded interface 36, spaced apart from the second rotating shaft 52. Both the first threaded interface 12 and the second threaded interface 36 are exposed on one side of the magnetic base 10, i.e., the side facing away from the mounting surface 411 of the quick-release clip 40. When the user mounts a camera with a quick-release clip onto the mounting surface 411, the two threaded interfaces can be used to connect external shooting accessories, such as a fill light. Of course, in other embodiments, the presence or absence of two threaded interfaces is not limited, and the location of the two threaded interfaces can also be configured as a cold shoe interface, a clip, a slot, or other mounting method.

[0032] Optionally, in conjunction with reference Figure 3 and Figure 4 In one embodiment, a first damping sleeve 55 is fitted on the outer side of the first rotating shaft 51, and / or a second damping sleeve 56 is fitted on the outer side of the second rotating shaft 52. The two damping sleeves can increase the rotational damping at the corresponding rotational position, thereby fixing the swing angle at both ends of the folding arm 20 and stabilizing the target shooting orientation of the folding magnetic bracket 1. Optionally, in other embodiments, the damping sleeves can be replaced by damping rings 54, or by rotation angle limiting structures, such as a mating structure of a protrusion and an arcuate groove, to limit the rotation angle.

[0033] Optionally, in conjunction with reference Figure 6 and Figure 8 The quick-release clamping block 42 includes a first clamping block 421, a positioning pin 422, and a first elastic element 423. The positioning pin 422 passes through the first clamping block 421 and the base 41 in sequence, so that the first clamping block 421 is rotatably connected to the base 41 with the positioning pin 422 as the rotation axis. The first elastic element 423 is disposed between the first clamping block 421 and the base 41. The two first clamping blocks 421 are rotatably connected to the opposite side walls of the base 41 in the form of a rocker switch. The opposite side walls of the base 41 are also provided with notches and grooves 412 for the first clamping blocks 421 to flip. Specifically, the first clamping block 421 includes a first locking block 4211 and a first pressing block 4212 connected together. A positioning pin 422 passes through the space between the first locking block 4211 and the first pressing block 4212. The first locking block 4211 extends out of the mounting surface 411. The elastic force provided by the first elastic element 423 drives the first locking block 4211 to automatically flip and engage in the quick-release latch, thereby securing the camera with the quick-release latch on the mounting surface 411. The first pressing block 4212 extends out of the outer wall of the base 41. Pressing the first pressing block 4212 causes the first locking block 4211 to flip outward simultaneously and disengage from the quick-release latch, thereby unlocking and releasing the camera with the quick-release latch from the mounting surface 411. Optionally, the first elastic element 423 may include, but is not limited to, a torsion spring 423a, a telescopic spring, or elastic rubber. The torsion spring 423a is penetrated by the positioning pin 422, and the telescopic spring or elastic rubber is located between the first pressing block 4212 and the base 41. The first clamp 421 in this embodiment is particularly suitable for shooting products that are equipped with DJI Action.

[0034] Further reference Figure 6 and Figure 8 In one embodiment, the quick-release clamp 40 includes a pair of positioning protrusions 45. The two positioning protrusions 45 protrude from opposite sides of the mounting surface 411 and are located inside the two first clamping blocks 421. The positioning protrusions 45 are used to engage with the positioning port of the camera to further improve the assembly stability of the camera. Of course, in other embodiments of this application, the positioning protrusions 45 may not be provided.

[0035] Optionally, refer to Figure 9In one embodiment, the quick-release clamp 42 includes a second clamp 424 and a second elastic member 425. The second elastic member 425 is disposed between the second clamp 424 and the base 41, and the second clamp 424 is slidably connected to the base 41 via the second elastic member 425. The second clamp 424 includes a second locking block 4241 and a second pressing block 4242 that are joined at an angle. The second locking block 4241 extends out of the mounting surface 411. The elastic force provided by the second elastic member 425 drives the second locking block 4241 to automatically move and engage in the quick-release latch, thereby securing the camera with the quick-release latch on the mounting surface 411. The second pressing block 4242 extends out of the outer wall of the base 41. Pressing the second pressing block 4242 causes the second locking block 4241 to move synchronously and disengage from the quick-release latch, thereby unlocking and releasing the camera with the quick-release latch from the mounting surface 411. Optionally, the second elastic member 425 may include, but is not limited to, a telescopic spring and elastic rubber. The second clamp 424 in this embodiment is adapted to mount the imaging product of the film.

[0036] Optionally, in conjunction with reference Figure 6 and Figure 8 The quick-release clamp 40 has a built-in magnetic suction element 46 located between two quick-release clamp blocks 42. When the quick-release clamp blocks 42 mount a camera with a quick-release bayonet onto the mounting surface 411, the magnetic suction element 46 magnetically engages with the mounting surface 411 to provide assembly stability for the quick-release clamp 40. Of course, in other embodiments, the magnetic suction element 46 may not be required.

[0037] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
