[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Example 1: Please refer to Figure 1-Figure 4In order to facilitate the driver to watch the navigation or the content displayed on the mobile phone screen when the mobile phone is being charged, the following technical contents are disclosed in this embodiment: a multi-directionally adjustable vehicle-mounted magnetic charger, comprising a magnetic charger body 1, which is used to magnetically charge the mobile phone; an elevation adjustment shaft 2 is fixedly connected to the lower end of the magnetic charger body 1, and the elevation adjustment shaft 2 is installed on a positioning frame 3, the positioning frame 3 is fixed to the upper end of the transverse steering shaft 4, and the lower end of the transverse steering shaft 4 is rotatably installed on the middle part of the upper end of the positioning suction cup 5; a locking mechanism 6 is installed on both the elevation adjustment shaft 2 and the transverse steering shaft 4, and the locking mechanism 6 is used to realize the position limitation of the rotationally adjusted elevation adjustment shaft 2 and the transverse steering shaft 4; the elevation adjustment shaft 2 and the positioning frame 3 are rotatably connected, and the positioning frame 3 is set as a "U"-shaped structure. The locking mechanism 6 includes a clamping nut 601 and a resistance increasing piece 602, and the clamping nut 601 is threadedly screwed on the elevation adjustment shaft 2 and the lateral steering shaft 4, and the inner surface of the clamping nut 601 is provided with a resistance increasing piece 602. The resistance increasing piece 602 and the clamping nut 601 are an integrally formed structure, and a plurality of resistance increasing pieces 602 are evenly distributed at equal angles on the inner surface of the clamping nut 601.

[0038] The magnetic charger body 1 is placed on the positioning frame 3. At this time, the magnetic charger body 1 rotates around the elevation adjustment shaft 2 at the lower end, so that the elevation angle of the magnetic charger body 1 can be easily adjusted. After the elevation angle is adjusted, the clamping nut 601 on the side of the elevation adjustment shaft 2 is screwed. At this time, the threaded clamping nut 601 moves toward the direction of the positioning frame 3. After the clamping nut 601 moves, the resistance-increasing sheet 602 thereon is in close contact with the side of the positioning frame 3, so that the position of the elevation adjustment shaft 2 can be fixed. Then, the transverse steering shaft 4 is rotated at the upper end of the positioning suction cup 5. The horizontal orientation of the magnetic charger body 1 can be adjusted by rotating the transverse steering shaft 4. After the adjustment of the magnetic charger body 1 is completed, the clamping nut 601 on the transverse steering shaft 4 is rotated so that the resistance-increasing sheet 602 at the lower end of the clamping nut 601 is in close contact with the upper end of the positioning suction cup 5, so as to fix the position of the transverse steering shaft 4. The viewing angle can be changed according to actual needs by adjusting the orientation of the magnetic charger body 1.

[0039] Embodiment 2: The technical content disclosed in this embodiment is an improvement made on the basis of the above embodiment 1. The existing car charger uses magnetic attraction to fix the mobile phone to be charged. However, when charging in the car, due to different road conditions and the frequent acceleration or sudden braking of the car, the magnetic attraction is not stable enough, which may cause the charged mobile phone to slip. In order to solve this technical problem, Figure 1 , Figure 2 and Figure 5As shown, the left and right sides of the magnetic charger body 1 are equipped with limiting mechanisms 7, which elastically clamp the sides of the mobile phone to ensure the stability of the mobile phone during charging. The limiting mechanism 7 includes a crossbar 701, and the crossbar 701 is fixed to the left and right sides of the lower end of the magnetic charger body 1. An adjustment block 702 is installed on the crossbar 701, and the adjustment block 702 is connected to the end of the crossbar 701 through a built-in spring 703. The adjustment block 702 forms an elastic telescopic structure through the built-in spring 703 and the crossbar 701.

[0040] When a mobile phone is placed on the magnetic charger body 1 for charging, the adjustment block 702 is pulled toward the outside of the cross bar 701. After the adjustment block 702 moves, the mobile phone is placed on the magnetic charger body 1. Then the adjustment block 702 is released. The adjustment block 702 resets and rebounds under the action of the built-in spring 703. The reset adjustment block 702 clamps and limits the mobile phone, thereby ensuring the stability of the mobile phone when charging on the magnetic charger body 1 while the vehicle is driving, and preventing the mobile phone from falling due to road bumps.

[0041] Embodiment 3: The technical content disclosed in this embodiment is an improvement made on the basis of the above-mentioned embodiments 1 and 2. When clamping and limiting the mobile phone, it is easy to cause unnecessary damage to the collection due to excessive clamping force. In order to solve this technical problem, Figure 5 and Figure 6 As shown, a clamping block 704 is provided inside the adjusting block 702, and a friction strip 705 is installed on the contact surface between the clamping block 704 and the side of the mobile phone, and a rubber pad 706 is installed between the clamping block 704 and the adjusting block 702. The rubber pad 706 is fixed between the clamping block 704 and the adjusting block 702 by bonding, and a plurality of friction strips 705 are evenly distributed on the surface of the clamping block 704.

[0042] When the adjusting block 702 is reset to fix the mobile phone, the clamping block 704 on its side first contacts the side of the mobile phone, and the friction strip 705 on the surface of the clamping block 704 can increase the contact friction with the side of the mobile phone. At the same time, the clamping block 704 can elastically deform its rubber pad 706 after being subjected to force. The elastic deformation of the rubber pad 706 can play a clamping and buffering role for the mobile phone, thereby avoiding damage to the mobile phone caused by excessive clamping force.
