Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone holders, in particular to a vehicle-mounted magnetic mobile phone holder. Background Art

[0002] A mobile phone car mount is a device installed inside a car to secure a mobile phone. It's used for navigation assistance, phone calls, information viewing, and multimedia entertainment. A common type of mobile phone car mount is the suction cup type. This type of mount has a strong suction cup at the bottom. Pressing the cup displaces the air inside, allowing atmospheric pressure to attach the mount to smooth surfaces like the car's windshield and dashboard. Some suction cup mounts can also conform to curved surfaces to a certain extent.

[0003] However, existing car mounts lack sufficient security, causing the phone to wobble, shift, or even fall off. For example, if a suction cup mount isn't completely vented during installation, or if the suction cup is old or dusty, it can easily lose suction when the vehicle vibrates, causing the phone to fall. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the suction cup type bracket easily loses suction during vehicle vibration, causing the mobile phone to fall, and to propose a vehicle-mounted magnetic mobile phone bracket.

Through the principle of electromagnetic induction, when an alternating current passes through the charging coil, the charging coil will generate an alternating magnetic field, thereby inducing an electromotive force in the wireless charging receiving coil of the mobile phone, thereby realizing wireless transmission of electric energy to charge the mobile phone battery. The capacitor plays a filtering and coupling role in the wireless charging circuit. The inner side surface of the shell one is rotatably connected to the shell two, and a receiving groove is provided on the side of the shell two. The inner wall of the receiving groove is fixedly connected to a rotating seat. Two rotating arms are arranged between the two rotating seats. Both ends of the rotating arm are fixedly connected to a hinge seat. The two rotating arms are rotatably connected to each other through the hinge seat.

[0014] 2. In the present invention, a receiving groove is provided in the second shell at both ends. When the second shell on both sides is completely folded, the two rotating arms are completely overlapped and folded, and fit against the inner wall of the receiving groove, thereby achieving a complete storage effect and reducing the occupied space.

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: Figure 1 - Figure 5 As shown, the utility model provides a vehicle-mounted magnetic mobile phone holder, comprising two shells 1, a mainboard 4 and a charging coil 5 are provided inside the shell 1, the inner side surface of the shell 1 is rotatably connected to the shell 2 8, the side surface of the shell 2 8 is provided with a receiving groove 9, the inner wall of the receiving groove 9 is fixedly connected to a rotating seat 10, two rotating arms 12 are provided between the two rotating seats 10, both ends of the rotating arms 12 are fixedly connected to an articulated seat 13, the two rotating arms 12 are rotatably connected to each other through the articulated seat 13, a rotating pin 14 is rotatably connected at the axis of the rotating seat 10, and the rotating arm 12 is rotatably connected to the rotating pin 14 through the articulated seat 13.

[0026] The following details the specific configuration and functions of this embodiment. The mainboard 4 includes electrical components such as a wireless charging control chip, a charging coil 5, capacitors, resistors, MOS tubes, and a crystal oscillator. The wireless charging control chip is responsible for communicating and negotiating with a receiving device such as a mobile phone to determine the appropriate charging power and mode, and controls operations such as starting and stopping wireless charging and power adjustment. Based on the principle of electromagnetic induction, when an alternating current passes through the charging coil 5, it generates an alternating magnetic field, which induces an electromotive force in the mobile phone's wireless charging receiving coil, thereby achieving wireless transmission of electrical energy and charging the mobile phone battery. The capacitor plays a filtering and coupling role in the wireless charging circuit.

[0027] The shell 2 8 is used to support the shells 1 at both ends. Two mutually folded rotating arms 12 are arranged between the two shells 2 8. The angle between the folded two rotating arms 12 and the angle between the folded rotating arms 12 and the rotating seat 10 can adjust the angle of the mobile phone holder between the mobile phone and the vehicle center console. The rotating arm 12 and the rotating seat 10 are plugged and positioned by a rotating pin 14, so that the rotating arm 12 rotates around the axis of the rotating pin 14 to avoid deviation. A receiving groove 9 is provided in the two shells 2 8. When the shells 2 8 on both sides are completely folded, the two rotating arms 12 are completely overlapped and folded, and fit against the inner wall of the receiving groove 9, thereby achieving a complete storage function. The mobile phone holder is folded into a cylindrical shape, and the mobile phone holder achieves a dual electric adsorption effect through the internal magnets 6 of the shells 1 at both ends.

[0028] Example 2: Figure 1 and Figure 4 As shown, a button 2 is provided on one side of the housing 1, and the power switch inside the mainboard 4 is controlled by the button 2. A charging port 11 is provided on the outer wall of the housing 1, and the battery in the mainboard 4 is charged through the charging port 11. A magnet 6 is provided on the outer wall of the housing 2 8, and the mobile phone is magnetically adsorbed by the magnet 6. A silicone plate 7 is fixedly connected to the outer wall of the housing 2 8, and the silicone plate 7 is arranged on the outside of the magnet 6. A suction cup 3 is fixedly connected to the bottom end of the housing 1, and the mobile phone holder is fixed to the vehicle's center console through the suction cup 3. A conductive swivel is provided inside the housing 1, and the conductive swivel supports 360° adjustment between the housing 1 and the housing 2 8.

[0029] The overall effect achieved by this embodiment is that a suction cup 3 is positioned at the bottom of housing 1. An air pump is used to pump out the air inside suction cup 3, creating negative pressure. Since the air pressure outside suction cup 3 is higher than the air pressure inside, atmospheric pressure presses suction cup 3 firmly against the surface, generating an adsorption force that allows the phone holder to conform to the surface of the vehicle's center console. A magnet 6 is positioned outside housing 2 8 to secure the phone via magnetic attraction. Magnet 6 can be a suitably sized electromagnetic coil. When current flows through the coil, a magnetic field is generated around the coil according to the law of electromagnetic induction. This magnetic field attracts the phone, achieving dual-mode magnetic and electric attraction. When in operation, the charging coil 5 generates an alternating magnetic field with a specific direction and intensity distribution to achieve power transmission. The magnetic field generated by magnet 6 is relatively fixed in direction. Generally, its direction is not completely aligned with that of the charging coil 5, and may even be perpendicular to each other. This minimizes interference between the magnetic field and the charging magnetic field.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
