Description

Technical Field

[0001] The invention relates to the field of mobile phone covers, in particular to a mobile phone cover capable of adjusting magnetic field strength. Background Art

[0002] With the development of society, people's living standards are constantly improving, and mobile phones are highly intelligent. Various types of mobile phones are emerging one after another, and mobile phone functions are increasing. By using applications, a variety of applications can be executed, such as schedule management, weather query, shopping, life payment, video entertainment, etc., providing a variety of convenient life functions. Mobile phones play an increasingly important role in people's lives and have become one of the necessities that people cannot do without.

[0003] However, since mobile phones are carried close to the body, they are easy to slip from the hand if one is not careful or negligent when using them, and the process of falling often causes different degrees of damage to the mobile phone. Therefore, in order to protect the mobile phone, people generally wear mobile phone cases. The design of mobile phone cases on the market is generally considered from the perspective of durability and heat dissipation. There is no protective structure to prevent the mobile phone from falling, resulting in poor anti-fall performance of the mobile phone case. In addition, the mobile phone case completely covers the mobile phone, and the contact area between the mobile phone case and the mobile phone is large, which is not conducive to the heat dissipation of the mobile phone. In addition, in order to be able to be firmly adsorbed on a supporting object or a mobile phone holder, a magnet is set on the mobile phone case. However, when the magnetic attraction of the magnet is too strong, it is not easy to remove it after being adsorbed on the supporting object or the mobile phone holder.

[0004] Therefore, it is necessary to develop a new technology to solve the above problems. Summary of the invention

[0005] In view of this, the present invention aims to solve the deficiencies in the prior art, and its main purpose is to provide a mobile phone case with adjustable magnetic field strength, which can effectively reduce the contact area between the main body and the mobile phone, thereby being more conducive to the heat dissipation of the mobile phone, can achieve the purpose of preventing the phone from falling, and can weaken the magnetic field strength of the magnetic suction part to facilitate removal.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A mobile phone case with adjustable magnetic field strength comprises a mobile phone case body, wherein the mobile phone case body comprises a main body and a frame connected to the upper end of the main body, wherein a housing cavity for housing a mobile phone is formed between the frame and the main body; the inner side wall of the main body facing the housing cavity is provided with a honeycomb structure, the outer side wall of each corner of the frame is provided with a buffer structure capable of elastic deformation, a magnetic attraction piece and an adjustment mechanism for adjusting the magnetic field strength of the magnetic attraction piece are provided in the outer bottom of the main body, the adjustment mechanism comprises an adjustment component and an adjustment button for controlling the adjustment component; the adjustment component can generate a magnetic field in the opposite direction to the magnetic field of the magnetic attraction piece under the triggering control of the adjustment button to weaken the magnetic field strength of the magnetic attraction piece.

[0008] As a preferred solution, the buffer structure is an air cushion buffer structure or an air bag buffer structure.

[0009] As a preferred solution, the buffer structure is protruding outwardly on the outer side wall of the corner of the frame, and a buffer space is provided between the buffer structure and the outer side wall of the corner of the frame.

[0010] As a preferred solution, an air cushion protrusion is provided at the upper end of each corner of the frame, and the air cushion protrusion protrudes upward from the upper surface of the frame.

[0011] As a preferred solution, the honeycomb structure is convexly provided on the inner side wall of the main body facing the accommodating cavity, and the surface of the honeycomb structure is used for contacting with the mobile phone.

[0012] As a preferred solution, the adjustment component includes a coil, a control circuit board and a battery, and the adjustment button, the coil and the battery are all connected to the control circuit board;

[0013] When the adjustment button is pressed, the control circuit board triggers the control of the coil to be energized so that the coil can generate a magnetic field in the opposite direction to the magnetic field of the magnetic attraction component; when the adjustment button is not pressed, the coil is de-energized.

[0014] As a preferred embodiment, the outer bottom of the main body is detachably connected to a back plate for preventing falling, and a mounting frame is arranged between the back plate and the outer bottom of the main body, and the mounting frame has an mounting cavity, a positioning cavity and a winding groove, the mounting cavity is arranged on a side of the mounting frame close to the main body, the positioning cavity is arranged on a side of the mounting frame close to the back plate, the winding groove is arranged on the surrounding side of the mounting frame and arranged on the periphery of the positioning cavity, the control circuit board and the battery are located in the mounting cavity, the magnetic suction part is located in the positioning cavity, the coil is wound in the winding groove, and the adjustment button is arranged on the side wall of the frame.

[0015] As a preferred solution, a clearance cavity is provided on the outer bottom of the main body, the mounting frame is positioned in the clearance cavity, and the back plate covers the clearance cavity.

[0016] As a preferred solution, the back panel and the main body are detachably connected via a snap-fit ​​structure, and the snap-fit ​​structure includes a first snap-fit ​​portion and a second snap-fit ​​portion that are snap-fitted to each other, the first snap-fit ​​portion is arranged on the outer wall of the frame, and the second snap-fit ​​portion is arranged on the back panel.

[0018] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical scheme that the back of the mobile phone can be in contact with the surface of the honeycomb structure on the main body mainly by setting the honeycomb structure, which can effectively reduce the contact area between the main body and the mobile phone, thereby being more conducive to the heat dissipation of the mobile phone. By setting an elastically deformable buffer structure on the outer side wall of each corner of the frame, when the mobile phone falls to the ground, it can absorb most of the kinetic energy through the deformation of the buffer structure, thereby protecting the mobile phone and achieving the purpose of anti-fall. In addition, by setting a magnetic suction piece and an adjustment mechanism for adjusting the magnetic field strength of the magnetic suction piece in the outer bottom of the main body, the adjustment mechanism includes an adjustment component and an adjustment button for controlling the adjustment component.
