Concrete implementation

[0018] The following section will explain exemplary embodiments in more detail, examples of which are shown in the drawings. Unless otherwise indicated, the following description refers to the drawings, and identical numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are only examples of devices and methods that correspond to some aspects of the present application, as detailed in the appended claims.

[0019] If it is currently necessary to connect the recording equipment to the stabilization equipment, a magnetic holder is usually used to connect the two through magnetic attraction. If the recording equipment does not need to be connected to the stabilization equipment, for example, if the user wants to support the recording equipment in a position such as on a desk, the magnetic holder cannot support it, and the practicality and convenience are poor.

[0020] To solve the problems in the related technology, the embodiment of the present application provides a magnetic holder equipped with a support ring that can switch between a stored state and an unfolded state, and when the support ring is in the unfolded state, the magnetic holder can support the recording equipment on its own, which improves the practicality and convenience of the magnetic holder for supporting the recording equipment and enhances the user experience.

[0021] According to an exemplary embodiment, the embodiment of the present application provides a magnetic holder comprising a body 10 and a support ring 20, and the support ring 20 has a stored state and an unfolded state, as shown in the Fig. 1, Fig. 2 to Fig. As shown in Figure 3, the support ring 20 is in a stored state; at this point, the magnetic holder can be used to magnetically connect a camera device (not shown in the drawing) to a PTZ (not shown in the drawing); as shown in the Fig. As shown in Figures 4-5, the support ring 20 is in an unfolded state in which the magnetic holder can be used to support the camera device on a support surface (not shown in the drawing). The camera device could be, for example, an electronic device with a recording function, such as a mobile device, a tablet computer, or a camera, and the support surface could be, for example, a tabletop, a work surface, or the like.

[0022] The body 10 has a first wall 101 and a second wall 102, which are opposite each other and thus facing away from each other, and the first wall 101 serves for magnetic connection with the camera device. The first wall 101 can have a variety of magnetic connections to the camera device. In one example, the first wall 101 can be magnetically connected to the metallic rear housing of the camera device. In another example, the first wall 101 can be magnetically connected to a magnetic sheet attached to the rear of the camera device. In yet another example, the first wall 101 can be magnetically connected to a wireless magnet of the camera device.

[0023] The support ring 20 is rotatably connected to the second wall 102 and is movable relative to the body 10. For example, the support ring 20 can have a first end section 21 and a second end section 22, which are located away from each other, or facing away from each other. The first end section 21 of the support ring 20 is rotatably connected to the second wall 102, and the second end section 22 of the support ring 20 is movable relative to the body 10 to move the support ring 20 between a retracted and an deployed state. When the support ring 20 is in a retracted state, the second wall 102 is magnetically connected to the stabilizing equipment. When the support ring 20 is in a deployed state, the second wall 102 and the support ring 20 form a holder to support the camera device on the mounting surface.

[0024] In the embodiment of the present application, the magnetic holder can support the recording equipment on its own, which improves the practicality and convenience of the magnetic holder for supporting the recording equipment and enhances the user experience.

[0025] In some embodiments, the magnetic holder comprises a first rotary assembly 30 and / or a second rotary assembly 40. In one example, the magnetic holder has a first rotary assembly 30 by which the support ring 20 is rotatably connected to the body 10, such that the support ring 20 switches between a stored state and an unfolded state. In another example, the magnetic holder comprises a second rotary assembly 40 by which the support ring 20 is rotatably connected to the body 10 to adjust the orientation of the support ring 20. In yet another example, the magnetic holder comprises a first rotary assembly 30 and a second rotary assembly 40 by which the support ring 20 is rotatably connected to the body 10, wherein the first rotary assembly 30 and the second rotary assembly 40 are capable of rotating the support ring 20 in different directions, e.g.,to rotate in relation to body 10 and at different angles in relation to the direction perpendicular to body 10.

[0026] In some embodiments, the magnetic holder comprises a first rotary assembly 30. As in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. As shown in Figure 7, the first rotary assembly 30 is connected to the body 10 or the support ring 20, the support ring 20 being rotatably connected to the body 10 via the first rotary assembly 30. Since, by way of example, a stop limit is created between the edge of the body 10 and the edge of the support ring 20, the opening and closing angle range between the support ring 20 and the body 10 can be set from 0 to 114°. Of course, it is understandable that this angle range can also be designed and adapted by a person skilled in the art according to actual needs, and the embodiment of this application does not unduly restrict this.

[0027] In one example, the first rotary assembly 30 comprises a rotary shaft 31 and a rotary frame 32. As in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. As shown in Figure 7, the rotating shaft 31 is rotatably connected to the second wall 102 of the body 10, and the rotating shaft 31 rotates about its axial direction, which is parallel to the surface of the second wall 102. The second connecting section 322 is fixedly connected to the support ring 20. The rotation of the rotating shaft 31 causes the rotating frame 32 to rotate, allowing the second end section 22 of the support ring 20 to move relative to the body 10. The support ring 20 can be opened and closed relative to the body 10, resulting in both the unfolded and retracted states.

[0028] It is understandable that in the embodiment of this application, the rotating frame 32 is attached to the rotating shaft 31 as an example. In actual production and construction, the rotating shaft 31 can also be attached to the body 10, and the rotating frame 32 can be attached relative to the rotating shaft 31. The embodiment of this application does not unduly restrict the specific adjustment method of the rotating shaft 31 and the rotating frame 32, as long as the rotating frame 32 can drive the support ring 20 to switch between the extended and stored states.

[0029] In some embodiments, the magnetic holder further comprises a second rotating assembly 40. As in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. As shown in Figure 7, the second rotary assembly 40 is connected to a first connecting section 321 of the rotary frame 32, which is rotatably connected to the body 10 via the second rotary assembly 40. The first rotary assembly 30 and the second rotary assembly 40 cause the support ring 20 to rotate in different directions. One of the first rotary assemblies 30 and the second rotary assembly 40 can open and close the support ring 20 relative to the body 10, and the other can rotate the support ring 20 in a direction perpendicular to the body 10 as the axis of rotation. By adjusting the first rotary assembly 30 and the second rotary assembly 40, the rotation and opening and closing of the support ring 20 can be achieved, which facilitates the adjustment of the support angle and direction and improves the flexibility of the magnetic holder.Among them, the rotation angle of the support ring 20 relative to the direction of the body 10 0 to 360° and can be rotatably adjusted by the user according to the usage requirements.

[0030] In some embodiments, the second rotary assembly 40 comprises a rotary mounting groove 41, a rotary seat 42, a first connecting piece 43, and a second connecting piece 44. The rotary mounting groove 41 is provided on the body 10 and extends through the body 10, wherein, for example, the rotary mounting groove 41 is designed as a circular groove or recess, wherein the projections of the rotary seat 42 and the second connecting piece 44 on the second wall 102 of the body 10 are each circular in order to achieve a rotation of the rotary seat 42 relative to the rotary mounting groove 41.The rotary seat 42 is rotatably connected in the rotary mounting groove 41, the rotary seat 42 rotates about its axial direction, the axial direction of the rotary seat 42 is perpendicular to the surface of the second wall 102, and the two ends of the rotary shaft 31 are rotatably connected to the rotary seat 42, so that the rotary shaft 31 can drive the support ring 20 about the axial direction of the rotary shaft 31 to rotate relative to the body 10.

[0031] The first connecting piece 43 is arranged on the side of the rotary mounting groove 41 facing away from the first rotary assembly 30, and the first connecting piece 43 is fixedly connected to the rotary mounting groove 41. A second connecting piece 44 is provided on the side of the first connecting piece 43 facing away from the first rotary assembly 30. A portion of the rotary seat 42 extends through this second connecting piece 44 and is fixedly connected to it, with the second connecting piece 44 being rotatably connected to it. The second connecting piece 44 serves to rotatably connect the rotary seat 42 to the first connecting piece 43, and the first connecting piece 43 is fixedly connected to the rotary mounting groove 41, so that the rotary seat 42 is rotatably connected to the rotary mounting groove 41.

[0032] Of course, it is also possible that, if the second connecting piece 44 is fixedly connected to the rotary seat 42, a part of the second connecting piece 44 extends through the first connecting piece 43 and is fixedly connected to the rotary seat 42. The embodiment of the present application does not unduly restrict the specific type of fixed connection between the second connecting piece 44 and the rotary seat 42, and the person skilled in the art can adjust it according to the actual requirements.

[0033] In one example, as in Fig. As shown in Figure 6, the first connecting piece 43 comprises a connecting body 431, which is a hollow structure, for example a circular body, which has a mounting space 432 in the center of the connecting body 431, and a part of the second connecting piece 44 is firmly connected to the second connecting piece 44 through the mounting space 432 with the rotary seat 42 in order to rotatably connect the rotary seat 42 to the first connecting piece 43.

[0034] The edge of the connecting body 431 is provided with a plurality of first fitting elements 433, and the plurality of first fitting elements 433 are arranged uniformly along the circumferential direction of the connecting body 431. The number and position of the first fitting elements 433 can also be adjusted by a person skilled in the art according to the actual requirements, and the embodiment of this application is not particularly restricted in this respect.

[0035] In one example, the first connecting piece 43 is further provided with several rotary feedback points 434 arranged uniformly in their circumferential direction. As in Fig. As shown in Figure 6, the rotary feedback point 434 is arranged on the connecting body 431. In the embodiment of the present application, the first connecting piece 43 is provided with eight rotary feedback points 434, i.e., each rotation of 45° passes through a rotary feedback point 434. It is understood that in the actual design and manufacture, the number of rotary feedback points 434 can also be increased or decreased, and the embodiment of this application does not impose any particular restrictions in this regard and can be adjusted by the person skilled in the art according to the actual requirements.

[0036] The rotary feedback point 434 can be located either on the side of the first connecting piece 43 adjacent to the rotary seat 42 or on the side of the first connecting piece 43 adjacent to the second connecting piece 44. If the rotary feedback point 434 is located on the side near the rotary seat 42, a rotation limiting element (not shown in the drawing) can be arranged on the rotary seat 42 near the first connecting piece 43. This element interacts with the rotary feedback point 434 to limit the rotation of the rotary seat 42 when it is rotated to different angles to achieve different rotation settings. One of the rotation limiting element and the rotary feedback point 434 is a clamping slot, and the other is a clamping block, and the rotation angle of the rotary seat 42 is limited by a clamping fit.If the rotary feedback point 434 is located on the side near the second connecting piece 44, a rotary limiting part of the second connecting piece 44 can be located near the first connecting piece 43, and the way in which the rotary limiting part and the rotary feedback point 434 snap and fit with the limit is the same as the way described above, which is not repeated here.

[0037] In some embodiments, the second wall 102 of the body 10 is provided with a receptacle 1021 for receiving the support ring 20. As in the Fig. 2, Fig. 3, Fig. 4 to Fig. As shown in Figure 5, the receiving section 1021 is an annular groove. When the support ring 20 is in a stored state, it is received in the receiving section 1021 to prevent it from protruding from the second wall 102 of the body 10, thus facilitating the magnetic connection of the body 10 to the stabilizing equipment.

[0038] In one example, the second end section 22 of the support ring 20 is provided with a deflection section 221. A gap exists between the deflection section 221 and the receiving section 1021, which makes it easier for the user to pull and unfold the support ring 20 from the position of the deflection section 221 and can also play a role in indicating the direction of operation.

[0039] In one example, the receiving section 1021 is further provided with a positioning groove 1022 in which a detection section 1023 is arranged. The positioning groove 1022 is used for snapping and positioning with the stabilizing equipment. When the second wall 102 is magnetically connected to the stabilizing equipment, a sensing section (not shown in the drawing) of the stabilizing equipment works in conjunction with the sensing section 1023 to detect the mounting position of the magnetic holder. The sensing element can be a switch, a sensor, or other device. When the second wall 102 is magnetically connected to the stabilizing equipment, the sensing element detects the sensing section 1023 in the positioning groove 1022, and the magnetic holder indicates, through tactile feedback, control circuit feedback, etc., whether the holder and the stabilizing equipment are installed in place.

[0040] In some embodiments, the body 10 comprises a base 13, a cover plate 14, and a magnet arrangement 15. As shown in Fig. As shown in Figure 7, a cover plate 14 is arranged on the first wall 101, which is firmly connected to the base 13 and has a receiving space between the base 13 and the cover plate 14, and the magnet arrangement 15 is arranged in the receiving space between the base 13 and the cover plate 14 to realize a magnetic connection.

[0041] In some embodiments, the magnetic arrangement 15 comprises a first magnetic arrangement and a second magnetic arrangement. The first magnetic arrangement is used to magnetically connect the camera device to the magnetic holder, and the second magnetic arrangement is used to magnetically connect the magnetic holder to the stabilization equipment.

[0042] In some embodiments, the body 10 comprises a first section 11 and a second section 12, which are connected to each other. As in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. As shown in Figure 7, the first rotary assembly 30 and the second rotary assembly 40 are located in the second section 12, i.e., the first end 21 of the support ring 20 is located in the second section 12 and the receiving section 1021 is located in the first section 11. That is, when the support ring 20 is in the stored state, the second end 22 of the support ring 20 is located in the first section 11.

[0043] In some embodiments, the first magnet arrangement comprises a first magnet 151 and a second magnet 152.

By way of example, the first magnet 151 is a ring magnet and the second magnet 152 is a square magnet, and the first magnet arrangement can be connected to a wireless charging magnet (not shown in the drawing) of the camera device by magnetic attraction.

[0044] In some embodiments, the second magnet arrangement includes a third magnet 153. As in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. As shown in Figure 7, a third magnet 153 is arranged on the first section 11, the first magnet 151 is arranged around the third magnet 153, and the third magnet 153 serves for magnetic connection with the stabilizing equipment, so that the magnetic holder is connected to the stabilizing equipment.

[0045] In some embodiments, the receiving space of the base 13 is provided with a mounting groove for mounting the magnet assembly 15, the shape of the mounting groove being adapted to the shape of the magnet assembly 15. As in Fig. As shown in Figure 7, the base 13 is provided with a first mounting groove 131 for mounting the first magnet 151, a second mounting groove 132 for mounting the second magnet 152 and a third mounting groove 133 for mounting the third magnet 153.

[0046] It is of course understandable that the number and shape of the individual magnets in the magnet arrangement 15 can be adapted by the person skilled in the art according to the actual needs, and the individual magnets can also be mounted on the base 13 by gluing, fastening connection, etc., and the embodiment of the present application does not restrict this too much.

[0047] In some embodiments, the parts of the magnetic holder are made of different materials and / or treated with different processes, and the parts of the magnetic holder can be assembled by gluing, snapping, fastener connection, etc., and the embodiments of this application do not restrict this too much.

[0048] Among them, the base 13, the support ring 20, the rotating shaft 31, the rotating frame 32, the rotary seat 42, the first connecting piece 43, and the second connecting piece 44 can utilize metal or alloy materials to ensure sufficient rigidity and strength and to guarantee support reliability. For example, the base 13, the support ring 20, and the rotary seat 42 can be made of an aluminum alloy material, such as AL6061, and the surface of each can be treated by sandblasting and anodizing to improve mechanical properties such as wear resistance, corrosion resistance, heat resistance, and hardness. A pattern can also be printed onto the surface of the base 13 by a laser engraving process to enhance its aesthetics.The rotating shaft 31 can be made of 1144 medium-carbon free-cutting steel, which offers the advantages of high purity, excellent material quality, and stable processing. It can also be given a protective film on its surface through a natural color-cleaning treatment to improve wear resistance and corrosion resistance. The rotating frame 32, the first connecting piece 43, and the second connecting piece 44 can be made of ASE1085 carbon steel to improve mechanical properties such as wear resistance, corrosion resistance, and hardness through natural color cleaning and heat treatment.

[0049] The first magnet assembly can use an N52 magnet and cold-rolled SPCC carbon steel, with chemically stable nickel and zinc plating forming the surface layers. The second magnet assembly can use an N52 magnet to improve corrosion resistance through nickel plating.

[0050] The cover plate 14 can be made of silicone gel, and patterns, designs and the like are printed onto the cover plate 14 by screen printing to improve the aesthetics of the cover plate 14.
