On the one hand, they need to frequently check the navigation information on their mobile phones while riding, which is not only dangerous but also violates traffic regulations. On the other hand, long-term use of mobile phone navigation and other functions will consume power quickly. If the power runs out during the trip, it will cause great inconvenience to the trip.

[0007] The housing structure comprises a housing and a heating plate, wherein the heating plate is mounted on the bottom of the housing, a conductive mother card is arranged on the heating plate at a position corresponding to the sealing cap, and a soft rubber suction cup is mounted on the outside of the top column.

[0008] Furthermore, the adjustment mechanism includes a sliding plate, which is slidably connected to the base of the charging seat mechanism, and a rotating gear is connected to the bottom of the top column. The sliding plate is provided with matching racks corresponding to the rotating gear positions. A bottom plate is provided at the bottom of the rotating gear, and the bottom plate is fixedly connected to the base. The top surface of the bottom plate is matched with the rotating gear through an extrusion assembly, so that the rotating gear is rotated and lifted by the cooperation of the extrusion assembly. The clamping mechanism includes two symmetrically arranged side clamps, and the two side clamps are L-shaped structures. The two side clamps are staggered and are matched with clamping gears at the staggered positions. The upper end of the clamping gear is matched with the tooth groove on the sliding plate through a passive gear.

[0009] Furthermore, the extrusion assembly includes a top block and an extrusion groove. The two top blocks are symmetrically arranged on the top surface of the bottom plate, and two extrusion grooves are formed at the bottom of the rotating gear corresponding to the top blocks.

[0016] A charging method for an anti-corrosion charging bracket:

[0017] a: Clip the phone onto the housing and connect the charging head to the charging port at the bottom of the phone. The phone is now connected via the seven conductive mother cards at the bottom of the heating plate. In cold weather, the heating plate is activated to provide temperature for the phone to avoid overcooling and failure to charge or shutdown.

[0018] b: In the initial position, the return spring squeezes the sliding plate, so that the matching rack and the rotating gear are in the initial position. At this time, the rotating gear is lifted, the conductive male card is not extended, and the conductive male card is retracted in the storage part of the rotating column. The rotating column rotates the conductive male card to be stored in the space of the sealing cap, and the conductive male card is not exposed, so it is isolated from the outside and corrosion will not occur;

[0019] c: Align the housing to the bottom gusset plate, and install the corresponding sealing cap downwards at the position of the conductive female card on the end face of the panel. At this time, because the conductive male card has not extended, the conductive female card can be easily stuck on the outside of the sealing cap, which is convenient for ensuring the initial connection;

[0020] d: Push the bottom buckle plate upwards, so that the bottom buckle plate drives the sliding plate to slide on the base. When the sliding plate slides, the matching rack cooperates with the rotating gear, and the rotating gear rotates, so that the conductive male card and the rotating column are driven to rotate until the edge of the extrusion groove contacts and squeezes the top block, and the rotating gear is lifted. Further, the conductive male card is squeezed by the deformation sheet and extends outward. At this time, the conductive male card and the conductive female card cooperate and lock to ensure power supply;

[0021] e: At the same time, since the sliding plate and the sliding top plate also slide on the locking block and pass over the locking block, the locking block of the locking block locks the top plate, and the shell is also locked through the cooperation of the bottom buckle plate and the conductive male card, and the soft rubber suction cup wraps the top column and the conductive female card, so they will not be exposed when power is turned on, thereby avoiding ionization and corrosion.

[0022] The beneficial effects of the present invention are as follows: the present invention utilizes the cooperation of the matching mechanism and the adjusting mechanism to store the conductive structure when not in use to avoid exposure, and also seals it when the power is turned on, thereby preventing the conductive elements from corroding and rusting, which affects the efficiency and safety of the wires. The telescopic conductive structure can also reduce resistance during installation and disassembly, thereby improving the use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] A charging method for an anti-corrosion charging bracket:

[0051] a: Clip the mobile phone onto the housing 11, and connect the charging head 12 to the charging port at the bottom of the mobile phone. At this time, the mobile phone is connected through the seven conductive mother cards 35 at the bottom of the heating plate 13, and the heating plate 13 is started in cold weather to provide temperature for the mobile phone to avoid overcooling and failure to charge or shutdown;

[0052] b: At the initial position, the return spring 52 squeezes the sliding plate 42, so that the matching rack 421 matches the rotating gear 44 in the initial position. At this time, the rotating gear 44 is lifted, and the conductive male card 33 is not extended. The conductive male card 33 is retracted in the storage portion of the rotating column 32, and the rotating column 32 rotates the conductive male card 33 to be stored in the space of the sealing cap 31. The conductive male card 33 is not exposed, so it is isolated from the outside and corrosion does not occur.

[0053] c: Align the housing 11 with the bottom buckle plate 41, and install the corresponding sealing cap 31 downward at the position corresponding to the conductive female card 35 on the end surface of the panel 22. At this time, because the conductive male card 33 has not extended, the conductive female card 35 can be easily stuck on the outside of the sealing cap 31, which is convenient for ensuring the initial connection;

[0054] d: Push the bottom buckle plate 41 upwards, so that the bottom buckle plate 41 drives the sliding plate 42 to slide on the base 21. When the sliding plate 42 slides, the matching rack 421 cooperates with the rotating gear 44, and the rotating gear 44 rotates, so that the conductive male card 33 and the rotating column 32 are driven to rotate until the edge of the extrusion groove 441 contacts and squeezes the top block 431, and the rotating gear 44 is lifted. In this example, the conductive male card 33 is squeezed by the deformation sheet and extends outward. At this time, the conductive male card 33 and the conductive female card 35 are locked together to ensure power supply;

[0055] e: At the same time, since the sliding plate 42 and the sliding top plate 55 also slide on the locking block 53 and pass over the locking block 53, the locking block of the locking block 53 locks the top plate 55, and the shell 11 is also locked through the cooperation of the bottom buckle plate 41 and the conductive male card 33, and the soft rubber suction cup 14 wraps the top column 34 and the conductive female card 35, and they will not be exposed when power is turned on, thereby avoiding ionization and corrosion.
