Description

Technical Field

[0001] This utility model relates to the field of camera equipment technology, and in particular to a magnetic bracket and camera assembly. Background Technology

[0002] In the field of mechanical manufacturing, magnetic adsorption devices are widely used in various equipment. Existing magnetic adsorption devices typically use magnets to attract iron sheets or magnets to each other, with the magnets usually magnetized along their height / thickness direction. Because traditional magnetic adsorption methods suffer from significant magnet leakage, larger, thicker, and stronger magnets are often chosen to enhance the magnetic attraction, inevitably increasing magnet costs. For compact products, larger and thicker magnets result in unnecessary space waste and increase the overall product size, indirectly raising costs. Furthermore, in consumer magnetic products, users prefer small and compact designs; an increased overall product size can lead to a loss of competitiveness. Utility Model Content

[0008] The further technical solution is as follows: the number of magnets is two, the magnetic conductive sheet is installed at the bottom of the pitch plate, and the two magnets are arranged side by side on the upper surface of the magnetic conductive sheet.

[0009] The further technical solution is as follows: the magnets are arranged side by side on the upper surface of the magnetic conductive sheet with opposite magnetic pole polarities.

[0010] A further technical solution is as follows: one end of the motherboard is recessed downward to form a first groove, and one end of the pitch plate is located in the first groove and hinged to the motherboard.

[0020] To better understand the technical content of this utility model, the technical solution of this utility model will be further introduced and explained below with reference to the schematic diagram, but it is not limited thereto.

[0021] Reference Figures 1 to 5 , Figures 1 to 5 A specific embodiment of the camera assembly 1 of this utility model is shown. In the embodiment shown in the figures, the camera assembly 1 includes a camera 200 and a magnetic bracket 100, wherein the magnetic bracket 100 includes a bracket body 10 and a magnet assembly 60 disposed within the bracket body 10. The magnet assembly 60 includes a magnetic conductive sheet 50 and at least two magnets 40, which are arranged side by side on the surface of the magnetic conductive sheet 50. At least two iron pieces 21 are disposed within the camera 200 at positions corresponding to the magnets 40 in the magnetic bracket 100, so as to cooperate with the magnets 40 to allow the camera 200 and the magnetic bracket 100 to be detachably assembled together by magnetic attraction. Based on the above design, the magnetic guide sheet 50 can function as a magnetic conductor. The magnetic leakage at the bottom of the magnet 40 can form a short-distance magnetic conduction loop through the magnetic guide sheet 50, effectively improving the magnetic circuit and significantly reducing the magnetic leakage of the magnet 40. This enhances the magnetic strength of the magnet assembly 60, providing stronger magnetic attraction and allowing the camera 200 to be placed more stably on the magnetic bracket 100. Furthermore, the iron sheet 21 inside the camera 200 also has good magnetic conductivity, acting as a magnetic guide sheet. The magnetic leakage at the top of the magnet 40 can also form a magnetic conduction loop through the iron sheet 21, enabling the magnetic field lines of the magnet assembly 60 to form a complete internal and external magnetic circulation loop, further reducing magnetic leakage and achieving the effect of a small magnet with a large magnetic force. Using the magnet assembly 60 provided by this invention, a small magnet can achieve a large magnetic force, meaning that the size of the magnet can be reduced to lower the cost of the magnet while maintaining the same magnetic strength. It also saves space to a large extent, reducing the overall size of the product and making the product's structural design more compact.

[0022] Furthermore, such as Figure 2 and Figure 5 As shown, in this embodiment, the magnetic poles of opposite sides of two adjacent magnets 40 have different polarities, and the magnetic poles at both ends of each magnet 40 have different polarities. Preferably, the magnets 40 are square magnets, and the magnets 40 are magnetized in half along their length and symmetrically arranged on the magnetic conductive sheet 50 with opposite polarities (e.g., Figure 5As shown in the figure, N and S represent the magnetic poles of magnet 40 respectively. Multiple magnets 40 can also form a magnetic circuit through magnetic conductive sheet 50 to further reduce the magnetic leakage of magnet 40.

[0023] In some embodiments, the support body 10 includes a main board 11 and a tilt plate 12 and a support plate 13 rotatably connected to both ends of the main board 11. The tilt plate 12 is used to connect to the camera 200, and the magnet assembly 60 is disposed within the tilt plate. Based on the above design, the tilt plate 12 and the support plate 13 are rotatably connected to both ends of the main board 11. When the camera 200 is placed on the tilt plate 12, its center of gravity can be relatively rearward to prevent it from tipping over. The relative rotation of the tilt plate 12 and the main board 11 can drive the camera 200 to rotate, completing the tilt action of the camera, and the tilt shooting angle of the camera 200 can be adjusted within a wider range.

[0024] continue Figure 2 , Figure 3 and Figure 4 As shown in the embodiment illustrated in the attached drawings, the number of magnets 40 is two, and the number of iron sheets 21 is also two. The pitch plate 12 includes a lower support plate 121 and an upper support plate 122 covering the lower support plate 121 and forming a receiving cavity 123 with the lower support plate 121. The two magnets 40 are respectively disposed on both sides of the receiving cavity 123. The magnetic conductive sheet 50 is mounted on the lower support plate 121, and the two magnets 40 are arranged side by side on the upper surface of the magnetic conductive sheet 50 with opposite magnetic polarities. In this embodiment, the upper support plate 122 and the lower support plate 121 are connected by adhesive backing, while the magnetic conductive sheet 50 and the magnets 40 can be fixed by dispensing adhesive. The upper support plate 122 is preferably made of silicone material to increase the contact friction between the camera 200 and the upper support plate 122, and to prevent the camera 200 from slipping when placed. Understandably, in some other embodiments, the number of magnets 40 can be increased or decreased according to actual needs.

[0025] Preferably, in some embodiments, one end of the main board 11 is recessed downward to form a first groove 111, one end of the pitch plate 12 is located in the first groove 111 and hinged to the main board 11 to realize the rotational connection between the pitch plate 12 and the main board 11, the bottom of the other end of the main board 11 is recessed upward to form a second groove 112, one end of the support plate 13 is located in the second groove 112 and hinged to the main board 11 to realize the rotational connection between the support plate 13 and the main board 11.

[0026] As attached Figure 3 and attached Figure 4As shown, the support body 10 further includes a first hinge shaft assembly and a second hinge shaft assembly. When the pitch plate 12 is located in the first groove 111, it is hinged to the main board 11 through the first hinge shaft assembly. When the support plate 13 is located in the second groove 112, it is hinged to the main board 11 through the second hinge shaft assembly. Specifically, the first hinge shaft assembly includes two first connecting shafts 711 and a first rolled piece 713. The second hinge shaft assembly includes two second connecting shafts 721 and a... The second roll of circular material 723, wherein the first roll of circular material 713 and the second roll of circular material 723 are respectively located within the tilt plate 12 and the support plate 13, the two first connecting shafts 711 are respectively disposed on both sides of one end of the main board 11, and both pass through the main board 11 and the first roll of circular material 713 and are located within the first roll of circular material 713, and the two second connecting shafts 721 are respectively disposed on both sides of the other end of the main board 11, and both pass through the main board 11 and the second roll of circular material 723 and are located within the second roll of circular material 723. Based on the above design, the tilt plate 12 rotates relative to the main board 11 with the first hinge axis assembly as the axis, and the support plate 13 rotates relative to the main board 11 with the second hinge axis assembly as the axis, forming a two-axis, three-plate structure, which is more conducive to the stability of the camera 200 after placement and the adjustability of the shooting angle.

[0027] In summary, this utility model's magnetic bracket achieves a strong magnetic attraction effect through the magnetic component with its internal array of small magnets, which magnetically engages with the iron sheet inside the camera. This improves magnetic leakage and enables a strong magnetic attraction between the bracket body and the camera. Specifically, during use, the iron sheet in the camera can magnetically connect with the magnet in the tilt plate of the bracket body, allowing the camera and the magnetic bracket to be integrated. The iron sheet also has good magnetic conductivity, acting as a magnetic guide sheet. In the camera assembly, the iron sheet and magnetic component are arranged in a "magnetic guide sheet-magnet-magnetic guide sheet" sequence from top to bottom. The magnetic leakage at the top of the magnet forms a magnetic conduction loop through the iron sheet, while the magnetic leakage at the bottom of the magnet forms a short-distance magnetic conduction loop through the magnetic guide sheet on its lower surface. This creates a complete internal and external magnetic circulation loop for the magnetic field lines of the magnetic component, resulting in a stronger and more concentrated magnetic force. This effectively improves the magnetic circuit without changing the magnet's volume, significantly reduces magnetic leakage, and enhances the magnetic attraction between the camera and the bracket body.
