Description

Technical Field

[0001] The present invention relates to the field of charging devices, and particularly to an anti-corrosion charging bracket and a charging method. Background Art

[0002] During the process of riding an electric vehicle, users often face the problems of using and charging mobile phones. On the one hand, when riding, it is necessary to frequently check the mobile phone navigation information. Holding the mobile phone is not only dangerous but also violates traffic regulations. On the other hand, when using functions such as mobile phone navigation for a long time, the power consumption is fast. If the battery runs out on the way, it will bring great inconvenience to the journey.

[0003] In the prior art, Chinese invention with publication number CN105932753B discloses a magnetic adsorption mobile phone charging bracket and a magnetic adsorption mobile phone charging device, which adsorbs and fixes the mobile phone through multiple positions. However, in rainy, snowy, cold, humid and low-temperature environments, traditional mobile phone brackets have no waterproof and moisture-proof functions, and use magnets to charge the mobile phone, which is bulky and costly. Due to reasons such as environmental humidity, the charging function of the mobile phone bracket will age and rust, affecting the service life and frequency, and the magnetic attraction between the mobile phone and the bracket is not firm and is prone to looseness and other problems. Summary of the Invention

[0004] The present invention provides an anti-corrosion charging bracket and a charging method to solve the technical problem that the conductive structure of the mobile phone bracket is exposed and rusts and corrodes in the exposed environment.

[0005] An anti-corrosion charging bracket of the present invention adopts the following technical solutions: It includes a housing mechanism for fixing the mobile phone, a charging base mechanism for cooperating with the housing mechanism to charge the mobile phone, and a matching mechanism for connecting the housing mechanism and the charging base mechanism. The matching mechanism is installed between the housing mechanism and the charging base mechanism, an adjusting mechanism is installed inside the charging base mechanism, a locking mechanism for locking the position of the adjusting mechanism is arranged inside the charging base mechanism, and clamping mechanisms are arranged on both sides of the charging base mechanism;

[0006] The matching mechanism includes a sealing cap. Seven sealing caps are fixedly installed on the top of the panel of the charging base mechanism, and the sealing cap is a hollow structure. A rotating column is rotatably installed inside the sealing cap. Three conductive male cards are circumferentially arranged on the outer circle of the rotating column. A top column is arranged at the central position of the rotating column. The conductive male cards are connected to the top column through deformation sheets, and through holes passing through the deformation sheets are arranged on the rotating column. The conductive male cards are inlaid and connected to the rotating column in the initial position. The bottom of the top column is connected to the adjusting mechanism, and the adjusting mechanism is used to adjust the rotation extension and retraction of the conductive male cards, so as to drive the conductive male cards to cooperate and connect with the top column on the housing mechanism;

[0007] The housing mechanism includes a housing and a heating plate. The heating plate is installed at the bottom of the housing. A conductive mother card is provided at a position on the heating plate corresponding to the sealing cap. A soft rubber suction cup is installed outside the top post.

[0008] Further, the adjustment mechanism includes a sliding plate. The sliding plate is slidably connected inside the base of the charging base mechanism. The bottom of the top post is connected to a rotating gear. Matching racks are provided at positions on the sliding plate corresponding to the rotating gear. A bottom plate is provided at the bottom of the rotating gear. The bottom plate is fixedly connected to the base. The top surface of the bottom plate cooperates with the rotating gear through an extrusion assembly, so that the rotating gear is rotated and lifted under the cooperation of the extrusion assembly. The clamping mechanism includes two symmetrically arranged side clamps. The two side clamps are of L-shaped structure and are arranged in a staggered manner. A clamping gear is provided at the staggered position. The upper end of the clamping gear is engaged with the tooth groove on the sliding plate through a passive gear.

[0009] Further, 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. Two extrusion grooves are formed at the bottom of the rotating gear corresponding to the top blocks.

[0010] Further, the material of the rotating post is hard rubber, and the material of the sealing cap is plastic. The position on the rotating post corresponding to the conductive male card is a receiving part, and the rest of the position is a matching part. When the matching part is matched with the sealing cap, it is a transition fit.

[0011] Further, the charging base mechanism further includes a charging head. The charging head is installed at the bottom of the housing and is electrically connected to the conductive mother card.

[0012] Further, the locking mechanism includes a limiting plate. The limiting plate is formed on the base. A top plate is provided at the bottom of the sliding plate. A return spring is provided between the top plate and the limiting plate. A lock block is provided at the bottom of the top plate. A release rod is provided on the side of the lock block. The locking mechanism 4 is used to drive the lock block to move horizontally so as to drive the lock block to release the top plate.

[0013] Further, the lock block includes a locking block and a U-shaped elastic plate. A groove for restricting the horizontal sliding of the lock block is provided on the panel.

[0014] Further, the extrusion groove is a fan-shaped opening, and a chamfer is formed at the edge position of the groove. The top block is of spherical structure.

[0015] Further, the charging base mechanism further includes a connecting plate. The connecting plate is connected to the bottom of the base by bolts. A ball head connecting seat is provided on one side of the connecting plate. A heating power supply line and a data line for supplying power to the conductive male card are also provided on the panel.

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

[0017] a: Clamp the mobile phone on the housing, connect the charger to the charging port at the bottom of the mobile phone. At this time, the mobile phone is connected through seven conductive female cards at the bottom of the heating plate, and the heating plate is activated in cold weather to provide temperature for the mobile phone, avoiding non-charging or shutdown due to excessive cold;

[0018] b: In the initial position, because the reset spring presses the sliding plate, the mating rack and the rotating gear are in the initial position state. At this time, the rotating gear is lifted, the conductive male card does not extend out, the conductive male card shrinks in the receiving part of the rotating column, and the rotating column rotates and houses the conductive male card in the space of the sealing cap. The conductive male card is not exposed, so as to be isolated from the outside and corrosion and other situations will not occur;

[0019] c: Align the housing with the position of the bottom buckle plate, and install the corresponding sealing cap downward at the position corresponding to the conductive female card on the end face of the panel. At this time, because the conductive male card does not extend out, the conductive female card can be easily clamped outside the sealing cap, which is convenient to ensure the initial connection;

[0020] d: Push up the bottom buckle plate, so that the bottom buckle plate drives the sliding plate to slide on the base. When the sliding plate slides, the mating rack cooperates with the rotating gear, and the rotating gear rotates, driving the conductive male card and the rotating column to rotate until the edge part of the extrusion groove contacts and presses the top block, and the rotating gear is lifted. Further, the conductive male card is extruded by the deformation piece and extends outwards. At this time, the conductive male card cooperates with the conductive female card to lock and ensure power-on;

[0021] e: At the same time, since the sliding plate slides and the top plate also slides on the lock block and crosses the lock block, the locking block of the lock block locks the top plate, and the housing 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, and it will not be exposed during power-on, thus avoiding ionization and corrosion.

[0022] The beneficial effects of the present invention are: The present invention uses the cooperation mechanism and the adjustment mechanism to cooperate to avoid exposure of the conductive structure when not in use, and also seals when the power is turned on, so as to avoid corrosion and rust of the conductive components, affecting the wire efficiency and safety. And the telescopic conductive structure can also reduce the resistance during installation and disassembly, improving the use effect. Description of the Drawings

Seven sealing caps 31 are fixedly installed on the top of the panel 22 of the charging base mechanism 2, and the sealing cap 31 is a hollow structure. A rotating column 32 is rotatably installed inside the sealing cap 31. Three conductive male cards 33 are circumferentially arranged on the outer circle of the rotating column 32. A top column 34 is arranged at the center position of the rotating column 32. The conductive male card 33 is connected to the top column 34 through a deformation piece, and a through hole passing through the deformation piece is arranged on the rotating column 32.

The position corresponding to the conductive male card 33 on the rotating column 32 is a storage part, and the rest of the positions are matching parts. When the matching parts are matched with the sealing cap 31, it is an interference fit.

[0045] In this embodiment, the charging base mechanism 2 further includes a charging head 12. The charging head 12 is installed at the bottom of the housing 11 and is electrically connected to the conductive mother card 35.

[0046] In this embodiment, the locking mechanism 5 includes a limiting plate 51. The limiting plate 51 is formed on the base 21. A top plate 55 is provided at the bottom of the sliding plate 42. A return spring 52 is provided between the top plate 55 and the limiting plate 51. A lock block 53 is provided at the bottom of the top plate 55.

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

[0051] a: Clamp the mobile phone on 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 female cards 35 at the bottom of the heating plate 13, and the heating plate 13 is activated in cold weather to provide temperature for the mobile phone to avoid non-charging or shutdown due to excessive cold;

[0052] b: At the initial position, since the return spring 52 presses the sliding plate 42, the mating rack 421 and the rotating gear 44 are in the initial position state. At this time, the rotating gear 44 is lifted, the conductive male card 33 does not extend out, the conductive male card 33 is retracted in the receiving part of the rotating column 32, and the rotating column 32 rotates and retracts the conductive male card 33 in the space of the sealing cap 31. The conductive male card 33 is not exposed, so as to be isolated from the outside and corrosion and other situations will not occur;

[0053] c: Align the housing 11 with the position of 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 face of the panel 22. At this time, since the conductive male card 33 does not extend out, the conductive female card 35 can be easily clamped outside the sealing cap 31, which is convenient to ensure the initial connection;

[0054] d: Push the bottom buckle plate 41 upward, 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 mating rack 421 cooperates with the rotating gear 44, and the rotating gear 44 rotates, driving the conductive male card 33 and the rotating column 32 to rotate until the edge part of the extrusion groove 441 contacts and presses the top block 431, and the rotating gear 44 is lifted. In this example, the conductive male card 33 is extruded by the deformation piece and extends outwards. At this time, the conductive male card 33 cooperates with the conductive female card 35 to lock and ensure power-on;

[0055] e: At the same time, since the sliding plate 42 slides, the sliding top plate 55 also slides on the locking block 53 and passes over the locking block 53, so that the locking block of the locking block 53 locks the top plate 55, and the housing 11 is also locked through the cooperation of the bottom buckle plate 41 and the conductive male card 33. Moreover, the soft rubber suction cup 14 wraps the top column 34 and the conductive female card 35 and will not be exposed when energized, thus avoiding ionization and corrosion.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
