Technical Field
[0001] This utility model relates to the technical field of electronic device components, and in particular to a magnetic bracket. Background Technology
[0002] In existing technologies, the back support brackets of mobile phone and tablet protective cases mostly adopt a fixed-angle buckle structure, which achieves single or limited angle support adjustment through preset slots or folding joints. Although this design can provide basic support functions, it has obvious limitations in actual use: users cannot flexibly adjust the device tilt angle according to usage scenarios (such as watching movies, video calls, office input), resulting in uncomfortable viewing angles or inconvenient operation. Utility Model Content
[0003] The main purpose of this invention is to provide a magnetic support bracket, which aims to improve the flexibility of the magnetic support bracket, facilitate 360-degree rotation and adjustment of the support position of the magnetic support bracket, and improve the user experience.
[0004] To achieve the above objectives, the magnetic holder proposed in this utility model includes:
[0005] A shell body, wherein a first limiting part is provided on the shell body;
[0006] A base, which is rotatably connected to the shell body;
[0007] A support base and a magnet, the support base being rotatably connected to the base, the magnet being mounted on the base or the support base; and
[0008] A gear assembly, comprising a gear ring, a limiting tooth, and an elastic element, wherein the limiting tooth is elastically connected to the base via the elastic element, the gear ring is provided with a second limiting portion, the gear ring is sandwiched between the base and the shell body, and the first limiting portion is limited to the second limiting portion, and the limiting tooth meshes with one of the tooth grooves of the gear ring.
[0009] In one embodiment, the first limiting portion is a first limiting protrusion, the second limiting portion is a first limiting groove, and the first limiting protrusion is limited to the first limiting groove.
[0010] In one embodiment, the shell body is provided with a first annular groove, the groove wall of the first annular groove is provided with a second annular groove, and the outer peripheral wall of the base is provided with a second limiting protrusion. The second limiting protrusion is located within the second annular groove so that the base is rotatably connected to the first annular groove.
[0011] In one embodiment, the second limiting protrusion is provided with a plurality of spaced protrusions.
[0012] In one embodiment, the base is provided with a second limiting groove, and the limiting tooth includes a plate body and a first tooth connected to each other. The plate body is limited in the second limiting groove, and the first tooth meshes with one of the tooth grooves of the gear ring.
[0013] In one embodiment, the elastic element is a spring.
[0014] In one embodiment, the plate body has a first mounting groove on the side away from the limiting tooth, the bottom of the first mounting groove has a limiting post, one end of the spring is connected to the base, and the other end of the spring is limited to the limiting post.
[0015] In one embodiment, the outer circumferential surface of the gear ring is provided with a plurality of second teeth at intervals, and the side of the second teeth facing the base has a straight section. The side of the first teeth facing the gear ring is arranged in an arc shape, and the side of the second teeth facing the base is arranged in a straight line.
[0016] In one embodiment, the support base has a third limiting protrusion on the side facing the base, and a second mounting groove is provided in the third limiting protrusion. The base has a third limiting groove on the side facing the support base. The magnet is installed in the second mounting groove. When the support base is closed to the base, the third limiting protrusion is limited to the third limiting groove.
[0017] In one embodiment, the magnetic bracket further includes a damping shaft, through which the support base and the base are rotatably connected.
[0018] In this invention, the angle between the support base and the base is adjusted by rotating the support base. The support base contacts a flat surface such as a desktop, allowing the electronic device inside the housing to be tilted and supported on the desktop at a predetermined angle. Simultaneously, a gear ring allows the base to rotate 360° relative to the housing. When adjusted to the predetermined angle, the limiting teeth mesh with the gears on the gear ring, fixing the base in a predetermined position. By rotating the base, the positions of the base and support base can be adjusted, allowing the housing to be supported in a predetermined orientation. This significantly improves the flexibility of the magnetic bracket, facilitating 360-degree rotation and adjustment of the support position, thus enhancing the user experience. Furthermore, because the limiting teeth are elastically connected to the base via an elastic element, a ticking sound is produced when the base is rotated, which has a relaxing effect on the user, reducing stress and further improving the user experience. Furthermore, the magnet can be used to magnetically attach to other external devices or to wireless charging devices to wirelessly charge electronic devices. Magnetic holders can be used in electronic devices such as mobile phones, tablets, and computers. Attached Figure Description

[0034] Reference Figures 1 to 4 This utility model proposes a magnetic holder, comprising:
[0035] A shell body 10, wherein a first limiting part is provided on the shell body 10;
[0036] Base 20, which is rotatably connected to the shell body 10;
[0037] A support base 30 and a magnet 40, wherein the support base 30 is rotatably connected to the base 20, and the magnet 40 is mounted on the base 20 or the support base 30; and
[0038] The gear assembly includes a gear ring 51, a limiting tooth 52, and an elastic element. The limiting tooth 52 is elastically connected to the base 20 through the elastic element. The gear ring 51 is provided with a second limiting part. The gear ring 51 is sandwiched between the base 20 and the shell body 10, and the first limiting part is limited to the second limiting part. The limiting tooth 52 meshes with one of the tooth grooves of the gear ring 51.
[0039] In the technical solution of this utility model, the angle between the support base 30 and the base 20 is adjusted by rotating the support base 30. The support base 30 is used to contact a flat surface such as a desktop, so that the electronic device inside the shell body 10 can be tilted and supported on the desktop at a predetermined angle. At the same time, by setting the gear ring 51, the base 20 can rotate 360° relative to the shell body 10. When adjusted to the predetermined angle, the limiting tooth 52 meshes with the gear on the gear ring 51 to limit the position, thereby fixing the base 20 in the predetermined position. By rotating the base 20, the positions of the base 20 and the support base 30 can be adjusted, so that the shell body 10 can be supported in a predetermined orientation. This greatly improves the flexibility of the magnetic bracket, facilitates 360-degree rotation and adjustment of the support position of the magnetic bracket, and improves the user experience. Meanwhile, since the limiting tooth 52 is elastically connected to the base 20 through an elastic element, each time the base 20 is rotated, the limiting tooth 52 and the groove wall of the outer peripheral tooth groove of the gear ring 51 will produce a ticking sound, which can relax the user and reduce stress, thereby further improving the user experience. Furthermore, the magnet 40 can be used for magnetic fixation with other external devices, or it can be magnetically fixed to the wireless charging device 62 to wirelessly charge electronic devices. The magnetic bracket can be used in electronic devices such as mobile phones, tablets, and computers.
[0040] Reference Figure 2 , Figure 5 as well as Figure 8 Specifically, the first limiting part is a first limiting protrusion 11, and the second limiting part is a first limiting groove 511. The first limiting protrusion 11 is limited by the first limiting groove 511. By setting the first limiting protrusion 11 and the first limiting groove 511, the gear ring 51 will not rotate during the user's rotation of the base 20. This allows the position of the base 20 to be fixed by the engagement of the limiting teeth 52 and the gear after the user has adjusted the orientation of the base 20. At the same time, the first limiting protrusion 11 and the first limiting groove 511 have a simple structure and are easy to process, thereby reducing the manufacturing cost of the magnetic bracket.
[0041] Reference Figure 2 , Figure 5 as well as Figure 6 Specifically, the shell body 10 is provided with a first annular groove 12, and the groove wall of the first annular groove 12 is provided with a second annular groove 13. The outer peripheral wall of the base 20 is provided with a second limiting protrusion 21, which is limited within the second annular groove 13, so that the base 20 is rotatably connected to the first annular groove 12. By installing the base 20 within the first annular groove 12, the thickness of the magnetic bracket is reduced, which is beneficial for the miniaturization of the magnetic bracket.
[0042] Furthermore, multiple second limiting protrusions 21 are spaced apart. By using multiple spaced second limiting protrusions 21 instead of directly forming a ring, the friction between the second limiting protrusions 21 and the wall of the second annular groove 13 is reduced during the rotation of the base 20, thereby improving the smoothness of the rotation of the base 20. At the same time, the multiple spaced second limiting protrusions 21 ensure that the base 20 can be firmly rotated and confined within the second annular groove 13, making it less likely to fall off, thus improving the stability and reliability of the base 20.
[0043] Reference Figure 3 and Figure 4 In one embodiment, the base 20 is provided with a second limiting groove 22, and the limiting tooth 52 includes a plate body 521 connected to it and a first tooth 522. The plate body 521 is limited in the second limiting groove 22, and the first tooth 522 meshes with one of the tooth grooves of the gear ring 51. By setting the second limiting groove 22, the plate body 521 can only move elastically within a limited space under the action of the elastic element, thereby improving the stability of the limiting tooth 52, avoiding the possibility of the limiting tooth 52 deviating, and thus improving the stability and reliability of the magnetic bracket during use.
[0044] Specifically, the elastic element is a spring 53. Spring 53 has a long service life, stable and reliable performance, and a low price, thereby reducing the manufacturing cost of the magnetic bracket and improving its stability and service life. Of course, in other embodiments, the elastic element can also be a silicone block, a compression spring, etc.
[0045] Furthermore, the plate body 521 has a first mounting groove on the side opposite to the limiting tooth 52, and a limiting post 523 is provided at the bottom of the first mounting groove. One end of the spring 53 is connected to the base 20, and the other end of the spring 53 is limited by the limiting post 523. By setting the limiting post 523, the lateral displacement of the spring 53 is prevented, and the limiting post 523 can also prevent the spring 53 from being over-compressed and damaged, thereby improving the service life of the spring 53 and improving the stability and reliability of the magnetic bracket.
[0046] Specifically, the outer circumferential surface of the gear ring 51 is provided with a plurality of second teeth 512 at intervals. The side of each second tooth 512 facing the base 20 has a straight section, while the side of the first tooth 522 facing the gear ring 51 is arc-shaped, and the side of the second tooth 512 facing the base 20 is straight. This ensures that the contact between the first tooth 522 and the second tooth 512 is a point-to-surface contact, thereby increasing the stability between the first tooth 522 and the second tooth 512 during the rotation of the base 20. When the flat surface and the arc-shaped surface are in contact, the sliding friction path is controllable, avoiding excessive wear caused by frequent sliding at the contact point of the arc surface.
[0047] Reference Figure 6 and Figure 7 In one embodiment, the support base 30 has a third limiting protrusion 31 on the side facing the base 20, and a second mounting groove 32 is provided in the third limiting protrusion 31. The base 20 has a third limiting groove 23 on the side facing the support base 30. The magnet 40 is installed in the second mounting groove 32. When the support base 30 is closed on the base 20, the third limiting protrusion 31 is limited to the third limiting groove 23. This ensures that when the support base 30 is closed on the base 20, the support cover will not shift laterally, thereby improving the stability and reliability of the support base 30.
[0048] Furthermore, the magnetic bracket also includes insulating paper 63, which is pasted and fixed to the opening of the second mounting groove 32. By setting the insulating paper 63, electrical leakage is avoided, thereby improving the safety of the magnetic bracket. The insulating paper 63 can be made of Mylar, PET, or other materials.
[0049] In one embodiment, the magnetic bracket further includes a damping pivot 61, through which the support base 30 and the base 20 are rotatably connected. By providing the damping pivot 61, the support base 30 can be rotated at any angle relative to the base 20 and then stopped, thereby improving the flexibility of the support base 30 and facilitating user adjustment, thus enhancing the user experience.
[0050] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
