TECHNICAL FIELD

[0001] The present invention relates to the technical field of mobile phone holders, and specifically relates to a magnetic mobile phone holder capable of automatic positioning and locking. BACKGROUND

[0002] Mobile phone holders for automobiles and outdoor cycling vehicles in the prior art cannot easily switch between landscape and portrait modes, and disassembly is required for switching between landscape and portrait modes. Additionally, during driving, a mobile phone may be detached from the holder due to sudden strong vibrations or improper manual operations. To overcome the defect that the mobile phone is not clamped by the mobile phone holder tightly, the present invention provides a magnetic mobile phone holder capable of automatic positioning and locking. SUMMARY

[0003] An objective of the present invention is to provide a magnetic mobile phone holder capable of automatic positioning and locking, so as to solve the technical problems mentioned in the above Background.

[0004] To achieve the above objective, the present invention adopts the following technical solution:

[0005] A magnetic mobile phone holder capable of automatic positioning and locking, including a base support, a positioning plate, and a mobile phone protection shell, where the positioning plate is fixedly mounted on the mobile phone protection shell, and the base support is connected to the positioning plate:

[0006] the base support includes a housing, a positioning protrusion is arranged at a top of the housing, and positioning grooves are formed at both ends of the positioning protrusion;

[0007] an elastically compressible pressing key is mounted at either of two inner ends of the housing, a latch tongue is fixedly arranged on the pressing key, the latch tongue extends into the positioning groove, a top of the latch tongue is flush with a top of the positioning protrusion, 2025204453   24 Sep 2026 and a first tangent plane is arranged at one end of the latch tongue away from the positioning protrusion;

[0008] an insertion end is arranged at one end of the positioning plate close to the base support, a second tangent plane is arranged on a circumferential face of the base support, and a snap-fit groove is formed at one end of the positioning plate away from the base support;

[0009] the positioning protrusion extends into an inner wall of the insertion end, and the latch tongue is connected to an inner wall of the snap-fit groove; and

[0010] a first magnet is fixedly mounted on an outer side of the top of the housing, a second magnet is fixedly mounted on an outer side of the positioning plate, the second magnet corresponds to the first magnet in position, and contact ends of the first magnet and the second magnet attract each other magnetically;

[0011] two pressing keys are slidably connected to inner walls of the housing at both ends thereof, a spring locating pin is fixedly arranged on either of the two pressing keys, anda spring is mounted between two spring locating pins to compress and subsequently rebound the latch tongues into engagement with the snap-fit grooves.

[0012] In a preferred embodiment of the present invention, a support connector is fixedly arranged at a bottom of the housing, and the wireless charging coil is mounted inside the housing.

[0013] In a preferred embodiment of the present invention, the wireless charging coil is electrically connected to a PBCA board, and the PBCA board is arranged inside the base support.

[0014] In a preferred embodiment of the present invention, a sealing plate is fixedly mounted at one end of the positioning plate away from the base support.

[0015] Additional aspects and advantages of the present invention will be set forth partially in the following description, which will become obvious in the following description, or may be learned by practice of the present invention.

[0016] When the rear end of the mobile phone protection shell is sufficiently close to the top of the housing, the annular first magnet and the second magnet begin to attract each other magnetically; during magnetic attraction, the positioning protrusion of the housing extends into the insertion end, and the first tangent plane of the latch tongue comes into contact with the second tangent plane; under the influence of magnetic attraction, the latch tongue moves toward a center due to an acting force from the first tangent plane and the second tangent plane, the spring is compressed, and the latch tongue extends into the snap-fit groove; when the first magnet comes into contact with the second magnet, the first tangent plane and the second 2025204453   24 Sep 2026 tangent plane are no longer in contact with each other, and the spring rebounds the latch tongue, such that an end portion of the latch tongue is snap-fitted into the snap-fit groove; the entire operation process requires only bringing the rear end of the mobile phone protection shell close to a top of the base support, and an effect of blind operation is achieved;

[0017] a spring rebounds the latch tongue, such that an end portion of the latch tongue is snap-fitted into the snap-fit groove, and the mobile phone protection shell is hardly detached from the base support, which enhances anti-vibration performance of the mobile phone holder; and

[0018] 360-degree rotation of the present invention is allowed without disassembly. BRIEF DESCRIPTION OF DRAWINGS
