[0093] Compared with the prior art, the charging base and the charging device have the following advantages:

[0094] 1. The charging base provided by the application is used for charging an electronic device, and the charging base comprises a shell and a charging assembly. The shell defines a receiving cavity, and an escape hole is formed in one side of the shell and communicates with the receiving cavity. A soft rubber part is installed in the receiving cavity, and part of the soft rubber part is exposed through the escape hole. The charging assembly comprises a circuit board arranged in the receiving cavity and a first charging head which can pass through the soft rubber part and is exposed to the shell. The first charging head is electrically connected to the circuit board, and the first charging head and at least part of the soft rubber part are movable relative to the shell. Compared with a conventional automatic alignment charging device, the charging base of the application is additionally provided with a soft rubber part around the charging assembly. The soft rubber part has the characteristics of good cushioning and easy deformation. When the electronic device needs to be charged, the charging assembly is automatically aligned with the charging port of the electronic device, and the soft rubber part moves correspondingly, so that the charging assembly does not come into frictional contact with the shell during movement, thereby avoiding frictional wear of the charging assembly caused by long-term movement and increasing the service life. In addition, the soft rubber part can also expand the movement range of the charging assembly due to its good ductility, thereby increasing the fault tolerance rate of the user during blind alignment charging.

[0095] 2. The soft rubber part of the charging base comprises a fixed part connected to the shell, a movable part surrounding the escape hole and exposed to the shell, and a curved part connecting the fixed part and the movable part. The movable part comprises a fixed groove arranged around the first charging head, and the movable part is movable relative to the shell. The curved part defines the movement range of the charging assembly. Due to the deformable characteristics of the soft rubber, the charging assembly can freely move within a certain range of the escape hole, and the curved part also separates the charging assembly from the edge of the escape hole, so that the charging assembly does not come into contact with the escape hole during movement, thereby reducing the wear.

[0096] 3. The fixed part of the charging base is provided with a plurality of mounting holes, and a plurality of mounting columns are correspondingly arranged in the receiving cavity. The mounting columns pass through the mounting holes to fix the soft rubber part.

[0097] 4. The movable part of the charging base is provided with an inclined surface inclined from the fixed groove to the curved part. The inclined surface is arranged to guide the movement direction of the charging assembly during movement.

[0098] 5. The size of the avoiding hole of the charging base is greater than the size of the first charging head and / or the depth of the accommodating cavity is greater than the height of the charging assembly, so that the first charging head drives the circuit board to move horizontally and / or vertically relative to the shell; the size relationship of the components is limited, which can ensure the free movement of the charging assembly while reducing the contact wear between the components.

[0099] 6. The shell of the charging base is provided with a chamfered slope around the edge of the avoiding hole; the friction between the soft rubber and the avoiding hole is reduced.

[0100] 7. The first charging head of the charging base comprises a connecting piece, which is a wire or a conductive spring piece or a spring probe; a fixing seat for fixing the connecting piece, a magnetic attraction piece arranged around the fixing seat, and a magnetic attraction seat body arranged around the magnetic attraction piece, the magnetic attraction seat body being arranged in a fixing groove; the charging assembly is a hierarchical structure surrounded layer by layer, which improves the safety during charging, and the magnetic attraction piece can drive the connecting piece to automatically align with the charging port of the electronic device when subjected to magnetic force.

[0101] 8.

[0102] 9. The maximum height of the magnetic attraction seat body is lower than the height of the horizontal plane where the avoiding hole is located; this design is to prevent the charging assembly from moving out of the range of the avoiding hole when connecting the electronic device, thereby improving the charging stability.

[0103] 10. The accommodating cavity of the charging base is further provided with a counterweight, and the shell is provided with a plurality of support columns on the opposite sides in the accommodating cavity, the support columns abutting against the counterweight; the setting of the counterweight can improve the stability of the whole device during charging of the electronic device, and the setting of the support columns in the accommodating cavity can limit the various parts in the accommodating cavity, thereby improving the stability of the charging base.

[0104] 11. The surface of the shell of the charging base is provided with a charging hole, the charging hole is in communication with the accommodating cavity, and a charging module is fixed on the side of the accommodating cavity close to the charging hole; one end of the charging module close to the charging hole is provided with a charging socket, and the other end is electrically connected with the circuit board; the setting of the charging module facilitates charging from the external power supply.

[0105] 12. The charging module of the charging base provided by the application is further provided with a fixing shell and a charging chip arranged in the fixing shell relative to one end provided with a charging socket; the fixing shell is arranged to protect the charging chip, thereby prolonging the service life.

[0106] 13.

[0107] 14. The inside of the backrest of the charging base is provided with support plates abutting against opposite sides of the backrest; the inside of the backrest is hollow, and the shape of the backrest supported by the support plates is not deformed, thereby reducing the weight of the charging base under the premise of facilitating support of the electronic device, and meeting the requirement of lightening.

[0108] 15. The end of the backrest of the charging base close to the avoiding hole is spaced apart from the edge of the avoiding hole; the spacing is arranged to enable the electronic device to be inclined against the backrest when being charged, so that the backrest provides stable support force to the electronic device, thereby improving the charging stability of the charging device.

[0109] 16. One side of the backrest of the charging base close to the avoiding hole is provided with a limiting slot; the limiting slot is a groove concave inwardly as a whole, and the purpose is to limit the movement of the electronic device against the backrest, thereby ensuring that the electronic device does not easily move due to external collision when being charged, and ensuring the stability of charging.
