Description

Technical Field

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

[0002] A magnetic bracket is a device that uses magnetic attraction to fix and support equipment. It typically consists of magnetic materials (such as neodymium iron boron magnets) and magnetically conductive components. Its core principle is to achieve quick installation, angle adjustment, and stable support through the attraction between the magnet and the equipment's built-in magnetic or metal plates, offering both convenience and flexibility. Currently, to ensure the stability of the connection between the magnet assembly and the main body, multiple protrusions are arranged around the circumference of the magnet assembly. Each protrusion has a connecting hole, and the main body has corresponding fixing holes. Bolts, inserted sequentially into the connecting and fixing holes, stably connect the magnet assembly and the main body together. However, because the protrusions are usually thin, outward-extending structures, their structural strength is relatively poor, resulting in low connection strength between the magnet assembly and the main body. Utility Model Content

[0003] The main purpose of this invention is to propose a magnetic support that aims to solve the technical problem of low connection strength between existing magnet components and the main body.

[0005] A housing having peripheral side walls that enclose a receiving cavity;

[0006] A magnetic component is disposed within the receiving cavity. Around the circumference of the magnetic component, the magnetic component is provided with a plurality of protrusions at intervals. The plurality of protrusions extend outward in a direction away from the vertical axis of the magnetic component. The magnetic component is connected to the housing through the protrusions.

[0007] Multiple clamping members are provided, each clamping member being disposed on the side of the protrusion away from the housing, for clamping the protrusion.

[0008] In some embodiments, the magnetic holder includes a support member with a receiving groove, and the magnetic element is disposed in the receiving groove so that the support member supports the magnetic element.

[0009] In some embodiments, a first connecting hole is provided in the receiving cavity, a second connecting hole is provided in the protrusion, and a third connecting hole is provided in the support member. Connectors are inserted into the first connecting hole, the second connecting hole, and the third connecting hole to connect the magnetic member and the support member to the housing.

[0010] In some embodiments, the first connecting hole, the second connecting hole, and the third connecting hole are all provided with internal threads, and the connector is provided with external threads. The external threads and the internal threads cooperate to realize the connection of the connector in the first connecting hole, the second connecting hole, and the third connecting hole.

[0011] In some embodiments, the clamping member is provided with a fourth connecting hole, and the connecting member is sequentially inserted into the fourth connecting hole, the second connecting hole, the third connecting hole and the first connecting hole to connect the clamping member, the magnetic member and the support member to the housing.

[0012] In some embodiments, a stepped surface is provided in the fourth connecting hole, the stepped surface being used to accommodate the end of the connector so that the end of the connector and the end face of the clamping member are flush.

[0013] In some embodiments, the clamping member is provided with a first insertion portion, and the support member is provided with a second insertion portion.

[0046] A magnetic holder is a device that uses magnetic attraction to fix and support equipment. It typically consists of magnetic materials (such as neodymium iron boron magnets) and magnetically conductive components. Its core principle is to achieve quick installation, angle adjustment, and stable support through the attraction between the magnet and the device's built-in magnetic or metal plates, offering both convenience and flexibility. For example, in the field of wireless charger technology, as electrical devices increasingly demand higher power quality, safety, and convenience, contact-based power transmission methods are becoming increasingly inadequate, leading to the development of contactless power transmission. Therefore, wireless chargers have emerged. Wireless chargers are devices that use the principle of electromagnetic induction for charging, and the magnetic component is an indispensable part of a wireless charger.

[0047] Currently, to ensure the stability of the connection between the magnet assembly and the main body, multiple protrusions are arranged circumferentially around the magnet assembly, each with a connecting hole. Corresponding to these connecting holes, the main body has fixing holes. Bolts, sequentially inserted into the connecting and fixing holes, are used to stably connect the magnet assembly and the main body together. However, because the protrusions are typically thin, outward-extending structures, their structural strength is relatively poor, resulting in low connection strength between the magnet assembly and the main body.

[0048] Based on this, in order to solve the technical problem of low connection strength between existing magnet components and the main body, referring to Figures 1 to 8 This utility model provides a magnetic holder 10 that can attract terminal devices (such as mobile phones, Bluetooth headsets, Bluetooth bracelets, etc.) for wireless charging. The magnetic holder 10 includes a housing 100, a magnetic component 200, and multiple clamping components 300. The housing 100 has side walls that enclose a receiving cavity 110. The magnetic component 200 is disposed within the receiving cavity 110. Around the circumference of the magnetic component 200, multiple protrusions 210 are spaced apart and extend outwards away from the vertical axis of the magnetic component 200. The magnetic component 200 is connected to the housing 100 through the protrusions 210. Further, the magnetic component 200 includes a magnet and a fixing plate. The magnet is disposed on the fixing plate, and the fixing plate has the protrusions 210. Multiple clamping elements 300 are provided corresponding to multiple protrusions 210. Each clamping element 300 is provided on the side of the protrusion 210 away from the housing 100 and is used to clamp the protrusion 210.

[0049] Specifically, in this embodiment, when assembling the magnetic bracket 10, the magnetic component 200 is first installed in the receiving cavity 110 of the housing 100. After the magnetic component 200 is positioned in the receiving cavity 110, it is connected to the housing 100 through the protrusion 210 (for example, the magnetic component 200 can be connected to the housing 100 by bolts that are sequentially inserted through the protrusion 210 and the housing 100). After the connection between the magnetic component 200 and the housing 100 is stable, the clamping component 300 is connected above the protrusion 210 corresponding to the position of the protrusion 210 (for example, the clamping component 300 can be connected above the protrusion 210 by bolts that are sequentially inserted through the clamping component 300 and the housing 100), so that the protrusion 210 is clamped between the housing 100 and the clamping component 300.

[0050] Alternatively, in some other embodiments, when assembling the magnetic bracket 10, the magnetic component 200 is first installed in the receiving cavity 110 of the housing 100. After the magnetic component 200 is positioned in the receiving cavity 110, the clamping component 300 is pressed on top of the protrusion 210 corresponding to the position of the protrusion 210. Then, the clamping component 300, the magnetic component 200 and the housing 100 are connected together (for example, the clamping component 300, the magnetic component 200 and the housing 100 can be connected together by bolts that are sequentially inserted through the clamping component 300, the protrusion 210 and the housing 100). Finally, the clamping component 300, the magnetic component 200 and the housing 100 form an integral structure, and the protrusion 210 is clamped between the housing 100 and the clamping component 300.

[0051] The clamping member 300 positioned above the protrusion 210 effectively protects the protrusion 210. When the magnetic bracket 10 is subjected to external impact, the clamping member 300 effectively buffers the impact, thereby reducing the impact or torsional force on the protrusion 210, ensuring the structural strength of the protrusion 210, and thus improving the connection strength between the magnetic component 200 and the housing 100. Moreover, by clamping the protrusion 210 with the clamping member 300, the positioning stability of the magnetic component 200 can be ensured, preventing the position of the magnetic component 200 from shifting, thereby maintaining the magnetic attraction of the magnetic bracket 10 to the terminal device and improving the stability of the terminal device during wireless charging.

[0052] In some embodiments, refer to Figures 1 to 3 ,as well as Figure 8The magnetic bracket 10 includes a support member 400, which is provided with a receiving groove 410. The magnetic member 200 is disposed in the receiving groove 410 so that the support member 400 supports the magnetic member 200. Specifically, in this embodiment, the magnetic component 200 is supported by the support member 400. On the one hand, the support member 400 can bear the weight of the magnetic component 200, ensuring that the magnetic component 200 will not sink or deform due to gravity. On the other hand, the support member 400 can position the magnetic component 200. By placing the magnetic component 200 in the receiving groove 410 of the support member 400, the magnetic component 200 can be accurately positioned at the target position, improving the positioning accuracy and stability of the magnetic component 200. Furthermore, the support member 400 can buffer the magnetic component 200. When the magnetic bracket 10 is subjected to external impact, the support member 400 can absorb and disperse the impact force, preventing the impact force from acting directly on the magnetic component 200, ensuring that the magnetic component 200 will not be damaged under external force, and extending the service life of the magnetic component 200.

[0053] In some embodiments, refer to Figures 1 to 3 ,as well as Figure 6 and Figure 8 For example, the magnetic component 200 can be in the form of a ring structure. In this case, the support component 400 can have a circular positioning groove 410 to match the structural shape of the magnetic component 200. After the magnetic bracket 10 is assembled, the inner peripheral wall of the magnetic component 200 will abut against the groove wall of the positioning groove 410, thereby improving the positioning stability of the magnetic component 200 on the support component 400 and preventing the magnetic component 200 from radially shifting.

[0054] In some embodiments, refer to Figures 1 to 8 The cavity 110 has a first connecting hole 111, the protrusion 210 has a second connecting hole 211, and the support member 400 has a third connecting hole 420. A connector 500 passes through the first connecting hole 111, the second connecting hole 211, and the third connecting hole 420 to connect the magnetic member 200 and the support member 400 to the housing 100. For example, the first connecting hole 111, the second connecting hole 211, and the third connecting hole 420 are all provided with internal threads, and the connector 500 is provided with external threads. The external threads and internal threads cooperate to realize the (threaded) connection of the connector 500 in the first connecting hole 111, the second connecting hole 211, and the third connecting hole 420.

[0055] Specifically, in this embodiment, when assembling the magnetic support 10, the magnetic component 200 is first placed in the receiving groove 410 of the support 400, ensuring that the second connecting hole 211 and the third connecting hole 420 are aligned. Then, the aligned magnetic component 200 and the support 400 are placed in the target position within the receiving cavity 110 of the housing 100, ensuring that the second connecting hole 211, the third connecting hole 420, and the first connecting hole 111 are aligned. Next, the end of the connector 500 is sequentially inserted into the second connecting hole 211, the third connecting hole 420, and the first connecting hole 111, achieving initial positioning between the magnetic component 200, the support 400, and the housing 100. Finally, tighten the connector 500 (preferably, an external tool such as a tap can be used to tighten the connector 500, saving time and effort and improving the tightening efficiency of the connector 500), so that the connector 500 is threadedly connected to the magnetic component 200, the support component 400, and the housing 100, achieving a tight connection between the magnetic component 200, the support component 400, and the housing 100. When disassembling or repairing the magnetic bracket 10, tighten the connector 500 in the opposite direction, so that the connector 500 can be pulled out from the first connecting hole 111, the second connecting hole 211, and the third connecting hole 420, and detached from the magnetic component 200, the support component 400, and the housing 100.

[0056] The magnetic chuck 10 is easy to assemble, disassemble, and maintain, requiring no specialized operating environment. The magnetic component 200, support component 400, and housing 100 are connected by threads, ensuring stable connections and preventing relative misalignment that could affect the performance of the magnetic chuck 10. Furthermore, the threaded connection ensures that the connection strength between the magnetic component 200, support component 400, and housing 100 is unaffected by the operating environment; even significant temperature changes will not cause the connection to loosen.

[0057] In some embodiments, refer to Figures 1 to 8 The clamping member 300 is provided with a fourth connecting hole 310. Connecting members 500 are sequentially inserted into the fourth connecting hole 310, the second connecting hole 211, the third connecting hole 420 and the first connecting hole 111 to connect the clamping member 300, the magnetic member 200 and the support member 400 to the housing 100.

[0058] Specifically, in this embodiment, by sequentially inserting connectors 500 into the fourth connecting hole 310, the second connecting hole 211, the third connecting hole 420, and the first connecting hole 111, the clamping member 300, the magnetic member 200, and the support member 400 can be connected to the housing 100 at once, thereby ensuring the structural integrity of the magnetic bracket 10. This connection method simplifies the connection steps between the various components during the assembly of the magnetic bracket 10, reducing the difficulty of connecting them (for example, too many connection steps lead to cumbersome and time-consuming steps, and also require high precision, at least ensuring the alignment accuracy between the holes, which directly increases the processing and assembly difficulty of the magnetic bracket 10), thereby improving the assembly efficiency of the magnetic bracket 10 and ensuring its assembly accuracy.

[0059] In some embodiments, referring to the specific structural design of the first connecting hole 111, the second connecting hole 211 and the third connecting hole 420, the fourth connecting hole 310 may be provided with an internal thread to match the specific structural design of the connector 500, thereby realizing a threaded connection between the clamping member 300 and the connector 500.

[0060] In some embodiments, refer to Figure 1 and Figure 7 The fourth connecting hole 310 is provided with a stepped surface 311, which is used to accommodate the end of the connector 500 so that the end of the connector 500 is flush with the end face of the clamping member 300. Specifically, in this embodiment, after the connector 500 is screwed into place, the end of the connector 500 can be just accommodated in the fourth connecting hole 310, so that the end of the connector 500 will not protrude out of the fourth connecting hole 310. By adopting the above structure, on the one hand, the relative position between the end of the connector 500 and the fourth connecting hole 310 can remind the operator whether the connector 500 is screwed in place, avoiding the operator's mistaken belief that the connector 500 is screwed in place due to jamming during screwing, which would ultimately lead to an unreliable connection between the various components of the magnetic bracket 10 and affect the performance of the magnetic bracket 10; on the other hand, by "concealing" the end of the connector 500 in the fourth connecting hole 310, the flatness of the end face of the magnetic bracket 10 can be ensured, improving the appearance of the magnetic bracket 10; furthermore, by accommodating the end of the connector 500 in the fourth connecting hole 310, the end of the connector 500 and the fourth connecting hole 310 can be locked together, preventing the connector 500 from being pulled outward under the action of external force, which would affect the connection stability between the various components of the magnetic bracket 10.

[0061] In some embodiments, refer to Figure 2 , Figure 7 as well as Figure 8 The clamping member 300 is provided with a first insertion portion 320, and the supporting member 400 is provided with a second insertion portion 430. The second insertion portion 430 and the first insertion portion 320 cooperate with each other to clamp the protrusion 210 between the clamping member 300 and the supporting member 400. For example, the first insertion portion 320 can be a plug-in post, and the second insertion portion 430 can be a plug-in hole; or, the first insertion portion 320 can be a plug-in hole, and the second insertion portion 430 can be a plug-in post. The plug-in post can be inserted into the plug-in hole to achieve a tight fit between the clamping member 300 and the supporting member 400.

[0062] Specifically, in this embodiment, when assembling the clamping member 300, the first insertion portion 320 is first inserted into the second insertion portion 430 to achieve pre-positioning between the clamping member 300 and the support member 400, so that the protrusion 210 is initially clamped between the clamping member 300 and the support member 400. At this time, the fourth connecting hole 310 will also be aligned with the second connecting hole 211 and the third connecting hole 420, so that the connector 500 can be sequentially inserted into the fourth connecting hole 310, the second connecting hole 211 and the third connecting hole 420, thereby improving the fitting accuracy between the connector 500 and each connecting hole. In addition, inserting the first insertion portion 320 into the second insertion portion 430 can achieve a limiting effect on the clamping member 300, preventing the clamping member 300 from deflecting and ensuring that the clamping member 300 always presses against the protrusion 210.

[0063] In some embodiments, refer to Figure 2 , Figure 7 as well as Figure 8 The clamping member 300 may be provided with two first insertion portions 320 at intervals, and correspondingly, the support member 400 may be provided with two second insertion portions 430 at intervals. Each first insertion portion 320 is inserted into each second insertion portion 430, which helps to improve the positioning effect of the clamping member 300 and prevents the clamping member 300 from rotating circumferentially.

[0064] In some embodiments, refer to Figure 2 , Figure 4 , Figure 5 as well as Figure 8 A first engaging portion 112 is provided within the receiving cavity 110, and a second engaging portion 440 is provided within the support member 400. The second engaging portion 440 and the first engaging portion 112 are connected to each other to position the support member 400 within the receiving cavity 110. For example, the first engaging portion 112 can be a engaging block, and the second engaging portion 440 can be a engaging groove. Alternatively, if the first engaging portion 112 is a engaging groove, the second engaging portion 440 can be a engaging block. The engaging block can engage into the engaging groove to achieve the engaging positioning of the support member 400 within the receiving cavity 110.

[0065] Specifically, in this embodiment, when assembling the support member 400, as the support member 400 gradually moves down within the receiving cavity 110, the second latching part 440 gradually abuts against the first latching part 112. After the second latching part 440 and the first latching part 112 abut against each other, the support member 400 will be positioned at the target position and target height within the receiving cavity 110. At this time, the support member 400 will not continue to move down within the receiving cavity 110, ensuring the positioning accuracy between the various components.

[0066] In some embodiments, refer to Figure 2 and Figure 7 The clamping member 300 has a mounting groove 330 at the protrusion 210, which is used to accommodate the protrusion 210. Specifically, in this embodiment, after the magnetic bracket 10 is assembled, the protrusion 210 is precisely embedded in the mounting groove 330, thereby allowing the clamping member 300 to better match the thickness of the protrusion 210, preventing the clamping member 300 from bulging at the protrusion 210 due to the thickness of the protrusion 210, and ensuring the tightness of the connection between the clamping member 300 and the support member 400. Moreover, by accommodating the protrusion 210 in the mounting groove 330, the clamping member 300 can more effectively protect the protrusion 210, preventing damage to the protrusion 210 from external impact forces.

[0067] In some embodiments, the depth of the mounting groove 330 and the thickness of the protrusion 210 are equal. With the above structure, on the one hand, it prevents the mounting groove 330 from being too shallow, which would prevent the mounting groove 330 from being unable to accommodate the protrusion 210, causing the clamping member 300 to have a slight bulge at the protrusion 210, affecting the connection stability between the clamping member 300 and the support member 400; on the other hand, it prevents the mounting groove 330 from being too deep, which would cause the structural strength of the clamping member 300 to deteriorate, making it impossible for the clamping member 300 to effectively protect the protrusion 210.

[0068] In some embodiments, refer to Figure 2 and Figure 4 A reinforcing rib 113 is provided within the receiving cavity 110. For example, the reinforcing rib 113 can be provided on the side wall of the receiving cavity 110. The material of the reinforcing rib 113 can be the same as that of the shell 100, in which case the reinforcing rib 113 and the shell 100 can be an integrally formed structure, thereby reducing the manufacturing difficulty of the shell 100 and improving the processing efficiency of the shell 100. The material strength of the reinforcing rib 113 can also be stronger than that of the shell 100, in which case the reinforcing rib 113 can provide more effective support and protection for the shell 100.

[0069] Specifically, in this embodiment, since the receiving cavity 110 is a hollow cavity, by providing reinforcing ribs 113 inside the receiving cavity 110, the structural strength of the shell 100 can be improved, preventing the shell 100 from easily deforming or breaking under stress, thereby helping to extend the service life of the shell 100.

[0070] It should be noted that other aspects of the magnetic support 10 disclosed in this utility model can be found in the prior art, and will not be repeated here.

[0071] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model.
