Technical Field

[0001] The utility model relates to the technical field of photographic accessories, in particular to a magnetic transfer seat. Background Art

[0002] When people go out, they like to take photos to record some good times. Compared with ordinary digital cameras, sports cameras have the advantages of small size, stable shooting, strong waterproof performance, etc., which greatly facilitates outdoor shooting and carrying. Sports cameras also have a special installation method that can be placed and shot anywhere at any time, allowing athletes to be both photographers and actors, such as underwater photography, skiing, cycling, mountaineering, etc., and enjoy sports without obstacles, so they are loved by the majority of users.

[0003] However, the current sports cameras on the market usually have only one external interface and can only be installed with the corresponding external structure. Therefore, when the sports camera needs to be installed with different external auxiliary devices through an adapter, the adapter needs to be installed with the sports camera at one end and the external auxiliary device at the other end. After the external device is installed at the other end of the existing adapter, other auxiliary shooting accessories cannot be connected, which limits the use scenarios of the adapter. Utility Model Content

[0004] The utility model provides a magnetic adapter to solve the technical problem that after the adapter is installed with an external device, other auxiliary shooting accessories cannot be connected, resulting in limited usage scenarios of the adapter.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A magnetic transfer seat, comprising:

[0007] The base has a first end surface and a second end surface opposite to each other along the thickness thereof, the first end surface is used for magnetically mounting the photographing device, and the second end surface is provided with a first cold shoe interface;

[0008] An adapter plate, rotatably connected to the second end surface and provided with an adapter hole;

[0009] The adapter plate can be flipped relative to the second end face to switch between a storage state and an open state. In the storage state, the adapter plate is stored in the first cold shoe interface; in the open state, the adapter plate allows the locking shaft to pass through the adapter hole provided thereon, and the first cold shoe interface is used for quick installation in conjunction with an external device.

[0010] In one of the embodiments, the bottom wall of the first cold shoe interface is provided with an elastic protrusion, the elastic protrusion accumulates and releases elastic force along the thickness direction of the base, and the elastic protrusion is supported between the bottom wall of the first cold shoe interface and the external device.

[0011] In one embodiment, the elastic protrusion is a conductive ejector pin, the conductive ejector pin is in electrical contact with an external device, and the conductive ejector pin and the first cold shoe interface form a hot shoe interface.

[0012] In one of the embodiments, a positioning hole is formed on a side of the adapter plate facing the first cold shoe interface, and when the adapter plate is in the storage state, the positioning hole is aligned and engaged with the elastic protrusion.

[0013] In one embodiment, the number of the adapter plates is two, the number of the first cold shoe interfaces is two, and when the adapter plates are in an open state, the adapter holes in the two adapter plates are opposite to each other.

[0014] In one embodiment, the base is provided with a mounting block between the two adapter plates, and the two adapter plates are rotatably connected to the mounting block via a rotating shaft; the mounting block is provided with a first threaded hole, and when the adapter plate is in a storage state, the first threaded hole can be used for a threaded connector to pass through.

[0015] In one embodiment, the second end surface is provided with a second threaded hole in an area outside the first cold shoe interface and the first threaded hole, and the second threaded hole can be used for the threaded connector to pass through when the adapter plate is in the storage state and the open state.

[0017] In one of the embodiments, the adapter plate is provided with an Alli positioning hole, and when the adapter plate is in the storage state, the Alli positioning hole is used for positioning the Alli connector.

[0018] In one of the embodiments, when the adapter plate is in the storage state, the outer surface of the adapter plate is flush with the second end surface.

[0019] It can be seen from the above technical solutions that the embodiments of the utility model have at least the following advantages and positive effects:

[0020] The magnetic adapter of the embodiment of the utility model includes a base and an adapter plate. The base has a first end face and a second end face relative to each other. The first end face is used to directly or indirectly magnetically mount the shooting equipment, and the second end face can be mounted on an external device through the adapter plate. The first cold shoe interface can also be used to mount photography auxiliary accessories such as a fill light, thereby expanding the external interface of the magnetic adapter, improving the practicality of the magnetic adapter, and making the magnetic adapter suitable for more usage scenarios. On the other hand, since the adapter plate can be folded and stored at the second end, and the adapter plate is just stored in the first cold shoe interface, the volume of the magnetic adapter in the storage state is reduced, thereby facilitating the carrying and use of the entire magnetic adapter.

[0030] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "disposed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] Combined with reference Figure 1 and Figure 2The utility model provides a magnetic adapter 10, which can be used to magnetically connect different sports cameras, and then install different sports cameras on other external devices through the magnetic adapter 10. Based on the external setting of the magnetic adapter 10 of the utility model, the above-mentioned external device can not only be an external device with a locking shaft, such as a common camera gimbal device; it can also be a photography auxiliary device and electronic device with a slider, or an external device with a bolt. Auxiliary shooting equipment and electronic equipment can be installed by sliding quick-installation, such as a camera gimbal, a flat surface, an uneven desktop or the ground, so that people can use sports cameras for shooting more conveniently during travel and get a better shooting experience. It should be understood that the magnetic adapter 10 of the present application can be connected and installed with external devices and photography auxiliary equipment on different opposite sides at the same time. The connected external device can be the sports camera mentioned above, or other shooting electronic devices such as mobile phones, tablets, cameras, etc.; photography auxiliary equipment can be a fill light, a flash, a support device, a quick-install structure, etc.

[0034] Combined with reference Figure 2 and Figure 3 The magnetic adapter 10 of the present application includes a rotatably connected base 100 and an adapter plate 200, the base 100 is used to be detachably connected to an external shooting device, and the adapter plate 200 is used to penetrate an external locking shaft to achieve fixation. Therefore, the external shooting device can be indirectly installed on an external device with a locking shaft through the magnetic adapter 10. Here, the external shooting device includes but is not limited to mobile phones, tablets, and cameras.

[0035] The adapter plate 200 is flipped relative to the magnetic adapter seat 10 so that the magnetic adapter seat 10 can switch between an unfolded state and a folded state, and the corresponding adapter plate 200 itself can switch between an open state and a stored state. Figure 2 It shows that when the adapter plate 200 is in the open state, the adapter plate 200 is turned outward away from the base 100 to form an angle with the base 100. Preferably, in this embodiment, when the adapter plate 200 is in the open state, the thickness direction of the adapter plate 200 is perpendicular to the thickness direction of the base 100. At this time, the adapter plate 200 can be used externally and provides the maximum external space, and the magnetic adapter 10 switches to the unfolded state. Figure 3It illustrates that when the adapter plate 200 is in the storage state, the adapter plate 200 is flipped toward the base 100 to be stored on one side of the base 100 and overlapped with the base 100. At this time, the adapter plate 200 is stored on one side of the base 100 and cannot be used externally, and the magnetic adapter 10 is folded up. Preferably, in this embodiment, when the adapter plate 200 is in the storage state, the thickness direction of the adapter plate 200 is parallel to the thickness direction of the base 100, and the adapter plate 200 fits tightly with the base 100, which minimizes the thickness of the entire magnetic adapter 10, makes the storage state more compact, and tends to be miniaturized, which is convenient for users to pick up and carry. It should be understood that in other embodiments of the present application, when the adapter plate 200 is in the open state, without considering the size of the adapter space, there is no limitation on whether the thickness direction of the adapter plate 200 is perpendicular to the thickness direction of the base; when the adapter plate 200 is in the stored state, without considering the storage volume and compactness, there is no limitation on whether the thickness direction of the adapter plate 200 is parallel to the thickness direction of the base 100.

[0036] Specifically, in conjunction with reference Figures 1 to 3 In order to clearly describe the present solution, the two opposite sides of the base 100 along its thickness direction are defined as a first end surface 110 and a second end surface 120, Figure 1 The first end surface 110 is shown as a magnetic attraction portion for magnetically attaching a motion camera. Figure 2 or Figure 3 It is shown that the second end surface 120 is provided with a first cold shoe interface 121 and is rotatably connected to the adapter plate 200 . Figure 2 It shows that when the adapter plate 200 is in the open state, the thickness direction of the adapter plate 200 is perpendicular to the thickness direction of the base 100, and the adapter hole 210 set on the adapter plate 200 is exposed for the locking shaft to pass through for connection and installation on the external device. At this time, the first cold shoe interface 121 is exposed for quick installation in conjunction with the external device. The first cold shoe interface 121 is for sliding quick installation of an external device with a slider, such as an external device with a quick release plate, a fill light, a flash, etc. Figure 3 It shows that when the adapter plate 200 is in the storage state, the thickness direction of the adapter plate 200 is parallel to the thickness direction of the base 100 and is stored in the first cold shoe interface 121. At this time, the adapter hole 210 is hidden in the first cold shoe interface 121, and the adapter plate 200 cannot be passed through by the locking shaft to achieve external installation. The first cold shoe interface 121 is filled with the adapter plate 200 and cannot be slid quickly by the slider to achieve external installation. The entire magnetic adapter seat 10 is folded and stored.

[0037] The magnetic adapter 10 of the utility model embodiment includes a base 100 and an adapter plate 200. The base 100 has a first end face 110 and a second end face 120 relative to each other. The first end face 110 is used for magnetic external connection. After the shooting device is directly or indirectly installed, the second end face 120 can install the shooting device on the external device through the adapter plate 200. The first cold shoe interface 121 can also be installed with a fill light and other photography auxiliary accessories, thereby expanding the external interface of the magnetic adapter 10, improving the practicality of the magnetic adapter 10, and making the magnetic adapter 10 suitable for more usage scenarios. Here, the first end face 110 can directly magnetically install a mobile phone or tablet. The first end face 110 can also magnetically absorb an adapter base with a magnet, and then install the sports camera on the adapter base, so that the sports camera is indirectly installed on the first end face. On the other hand, since the adapter plate 200 can be folded and stored in the second end surface 120, and the adapter plate 200 is just stored in the first cold shoe interface 121, the volume of the magnetic adapter 10 in the stored state is reduced, thereby facilitating the carrying and use of the entire magnetic adapter 10.

[0038] Preferably, in combination with reference Figure 4 and Figure 5 In this embodiment, the first end surface 110 is provided with a magnetic attraction portion 111 and an installation cavity 112. The magnetic attraction portion 111 is contained and limited in the installation cavity 112. The magnetic attraction portion 111 is used for detachable magnetic attraction installation of the motion camera. The magnetic attraction portion 111 includes a first buffer pad 111a, a first magnet 111b, and a second buffer pad 111c stacked in sequence. The first buffer pad 111a and the second buffer pad 111c are respectively arranged on opposite sides of the first magnet 111b along its thickness direction. The first buffer pad 111a covers the first magnet 111b, and the motion camera is adsorbed and installed on the first buffer pad 111a through the magnetic attraction with the first magnet 111b. The second buffer pad 111c covers the bottom wall of the installation cavity 112. Figure 4 It is illustrated that the first magnet 111b of this embodiment is in a ring shape, and the corresponding installation cavity 112 and the second buffer pad 111c are both in a ring shape, so that the magnetic attraction of the magnetic attraction part 111 is uniform in a ring shape. It should be understood that in this application, firstly, the number and shape of the first magnet 111b are not limited, and it is only necessary to satisfy that the first end face 110 can be magnetically installed; secondly, the first buffer pad 111a is used to separate the motion camera base and the first magnet 111b to prevent the direct contact between the two from causing friction and wear, and to protect the motion camera. The second buffer pad 111c is used to separate the first magnet 111b and the bottom wall of the installation cavity 112 to prevent the direct contact between the two from causing friction and wear. In this application, whether the first buffer pad 111a and the second buffer pad 111c are provided is not limited, and the materials used to make the two are not limited.

[0039] Preferably, in combination with reference Figure 2 or Figure 3 In this embodiment, the base 100 is further provided with a second cold shoe interface 122 on the second end surface 120. The second cold shoe interface 122 is arranged at a position that does not interfere with the arrangement of the adapter plate 200. Therefore, whether the adapter plate 200 is in the storage state or the open state, the second cold shoe interface 122 can be used for quick installation with an external device. It should be understood that the second cold shoe interface 122 is provided only for the sports camera to obtain more expansion interfaces through the magnetic adapter 10. In other embodiments of the present application, the second cold shoe interface 122 is not limited.

[0040] Preferably, in combination with reference Figure 2 and Figure 4 , the bottom wall of the first cold shoe interface 121 and the second cold shoe interface 122 is provided with an elastic protrusion 123, and the elastic protrusion 123 accumulates and releases elastic force along the thickness direction of the base 100. When the external device is slidably installed in the first cold shoe interface 121 and the second cold shoe interface 122, the elastic protrusion 123 abuts between the bottom wall and the external device, so as to more stably install and connect the external device in the first cold shoe interface 121 and the second cold shoe interface 122. It should be understood that, firstly, without considering the installation stability of the external device, in other embodiments, the elastic protrusion 123 is not necessarily provided; secondly, in other embodiments, the elastic protrusion 123 can be provided in one of the first cold shoe interface 121 and the second cold shoe interface 122. Therefore, in the present application, whether the elastic protrusion 123 is provided or not is not limited, and the setting position and number of the elastic protrusion 123 are not limited.

[0041] Preferably, in another embodiment, the elastic protrusion 123 is a conductive pin with an electrical property. At this time, the first cold shoe interface 121 and the second cold shoe interface 122 can be used as hot shoe interfaces, and the second end surface 120 can realize data or power transmission with some electronic products through the hot shoe interface.

[0042] Preferably, reference Figure 4 and Figure 6 In this embodiment, a positioning hole 220 is provided on one side of the adapter plate 200 facing the first cold shoe interface 121. When the adapter plate 200 is flipped to the storage state, the positioning hole 220 on the adapter plate 200 is aligned and engaged with the elastic protrusion 123 to enhance the storage stability of the adapter plate 200 in the first cold shoe interface 121. It should be understood that, without considering the storage stability of the adapter plate 200, in other embodiments of the present application, whether the positioning hole 220 is provided or not is not limited.

[0043] Preferably, in combination with reference Figure 5 and Figure 6A metal screw 124 is further provided in the first cold shoe interface 121, one end of the metal screw 124 is exposed at the bottom wall of the first cold shoe interface 121, and the adapter plate 200 is further provided with a second magnet 230.

It should be understood that, firstly, without considering the storage stability of the adapter plate 200, in other embodiments of the present application, the provision of the metal screw 124 and the second magnet 230 is not limited; secondly, in other embodiments, the provision positions of the metal screw 124 and the second magnet 230 are exchanged, and the metal screw 124 can also be in a magnet state, as long as the adapter plate 200 can be further magnetically absorbed in the first cold shoe interface 121 in the storage state.

[0044] Preferably, in this embodiment, reference Figure 3 The adapter plate 200 is also provided with an Arri positioning hole 240. When the adapter plate 200 is in the storage state, the Arri positioning hole 240 is used for positioning and connecting a device with an Arri connector. It should be understood that the Arri positioning hole 240 is provided only for the sports camera to obtain more expansion interfaces through the magnetic adapter 10. In other embodiments of the present application, the provision of the Arri positioning hole 240 is not limited.

[0045] Preferably, in this embodiment, reference Figure 3 , the number of adapter plates 200 is two, the number of first cold shoe interfaces 121 is two, each for receiving two adapter plates 200, and the number of adapter holes 210, positioning holes 220, second magnets 230, and Arley positioning holes 240 are all two. When the adapter plate 200 is in the open state, the two adapter holes 210 are opposite to each other for the locking shaft to pass through. It should be understood that in the present application, the number of adapter plates 200 and the number of corresponding structures are not limited, and can be two, one, or more than two.

[0046] Preferably, in this embodiment, combined with reference Figure 3 and Figure 5 The base 100 is also provided with a mounting block 130 between the two adapter plates 200, and the two adapter plates 200 are both rotatably connected to the mounting block 130 via a rotating shaft 140. In addition, the mounting block 130 is provided with a first threaded hole 131, and when the adapter plates 200 are in the storage state, the first threaded hole 131 is used for threaded connection members to pass through and fix. Figure 5In the embodiment, the mounting block 130 is fixedly connected by the metal screw 124.
