This application claims priority to Chinese patent application No. 202310548630.1 filed with the China National Intellectual Property Administration (CNIPA) on May 16, 2023, the disclosure of which is incorporated herein by reference in its entirety.
The present disclosure relates to the technical field of charging devices and, in particular, an automatic winding module and a highly interchangeable charging module.
A power supply product currently on the market is basically designed with a separate power supply and a separate output line. Alternatively, the power supply product is designed with a direct connection line.
A conventional combination of a power supply and an output line generally meets people's living needs and is relatively convenient to carry. However, with a fixed length, the output line may be short or long when used, that is, the output line has a redundant length when a charging device is relatively close to a socket, or the output line is not long enough when the charging device is relatively far away from the socket. For this reason, it is difficult to have a proper length of the output line, or it is time-consuming and messy to store the output line. Moreover, the power supply needs to be plugged in or out to match with the socket every time the power supply is used, and the plugging process is affected by the quality of the socket. Since an elastic clip is disposed in the socket to grip a latch on the plug, repeated plugging in and out are prone to lead to a loosening of the combination of the latch and the elastic clip, thus causing the plug to easily fall from the socket and affecting the user experience.
The power supply product with a direct connection line has a relatively large overall volume, and the output line can be used only by being fixed to the existing power supply and cannot be used interchangeably.
Therefore, there is an urgent need to study an automatic winding module and a highly interchangeable charging module to avoid the following cases. The length of an output line is improper, the output line is difficult to store, a plug easily falls from a socket due to repeated plugging in and out between the plug and the socket, and the output line cannot be interchangeably used with other power supplies.
The present disclosure aims to provide an automatic winding module and a highly interchangeable charging module.
To achieve the preceding purposes, the present disclosure provides the technical schemes described below.
The present disclosure provides an automatic winding module. The automatic winding module includes a winding housing, a winding assembly, a first connection assembly, and a first charging assembly.

The present disclosure provides an automatic winding module. In the automatic winding module, a winding assembly is disposed in the winding housing so that an output line can be wound in the winding housing. In this manner, any length can be extracted within the range of the total length of the output line when in use, and thus the improper length of the output line and difficulty in storage are avoided. A first connection assembly is configured to be detachably adsorptively connected to a power supply base output member. The power supply base output member has a second connection assembly. The first charging assembly is configured to abut against and be electrically connected to a second charging assembly of the power supply base output member in a state in which the first connection assembly is adsorptively connected to the second connection assembly. The plugging in/out structure is replaced with the adsorptive structure so that repeated plugging operations of the power supply base output member are prevented, thereby avoiding the loosening of plugging assemblies. The adsorptive connection ensures the reliability of the connection between the automatic winding module and the power supply base output member. In addition, a power supply base output member, as long as provided with the second connection assembly, may be connected to the automatic winding module and can achieve an electrical connection via the first charging assembly and the second charging assembly. In this manner, the interchangeability between the automatic winding module and different categories of power supply base output members is implemented.

As shown in
It should be noted that the structure of the winding assembly and the method of winding the output line 140 are well-known to those skilled in the art. To save space, details are not described herein.
In the automatic winding module 100, the winding assembly is disposed in the winding housing 110 so that the output line 140 can be wound in the winding housing 110. In this manner, any length can be extracted within the range of the total length of the output line 140 when in use, and thus the improper length of the output line 140 and difficulty in storage are avoided. The first connection assembly 120 is configured to be detachably adsorptively connected to the power supply base output member 200 has the second connection assembly. The first charging assembly 130 is configured to abut against and be electrically connected to the second charging assembly 220 of the power supply base output member 200 in a state in which the first connection assembly 120 is adsorptively connected to the second connection assembly 210. The plugging structure is replaced with the adsorptive structure so that the repeated plugging operations of the power supply base output member 200 are prevented, thereby avoiding the loosening of plugging assemblies. The adsorptive connection ensures the reliability of the connection between the automatic winding module 100 and the power supply base output member 200. In addition, as long as a power supply base output member 200 is provided with the second connection assembly 210, the power supply base output member 200 may be connected to the automatic winding module 100 and can achieve an electrical connection via the first charging assembly 130 and the second charging assembly 220. In this manner, the interchangeability between the automatic winding module 100 and different categories of power supply base output members 200 is implemented.
An accommodation slot 111 is disposed at the outer circumference of the winding housing 110. A through hole communicating the accommodation slot 111 with the inner cavity of the winding housing 110 is disposed in the winding housing 110. The output line 140 is disposed through the through hole and is wound around the winding assembly. The accommodation slot 111 is configured to accommodate a charging head 141 of the output line 140. The configuration of the accommodation slot 111 enables the output line 140 to be stored more accurately.
The inner cavity of the winding housing 110 is provided with a magnet. The charging head 141 of the output line 140 is at least partially made of magnetic attractive material. The charging head 141 of the output line 140 which is located in the accommodation slot 111 is capable of being adsorbed by the magnet.
With respect to the first connection assembly 120, in this embodiment, the first connection assembly 120 includes a first magnetic attractive member disposed in the inner cavity of the winding housing 110. In this embodiment, the second connection assembly 210 may be a second magnetic attractive member or be made of magnetic attractive material.
In other embodiments, the first connection assembly 120 may be made of magnetic attractive material, and the second connection assembly 210 may be a magnetic attractive member.
The first magnetic attractive member is a permanent magnet. The second magnetic attractive member is a permanent magnet. The magnetic attractive material is stainless steel or iron.
To achieve a stable connection between the automatic winding module 100 and the power supply base output member 200, multiple first magnetic attractive members are provided in this embodiment and arranged in a ring shape. In this embodiment, the second connection assembly 210 may be a second magnetic attractive member, and multiple second magnetic attractive members are provided and arranged in a ring shape. The multiple second magnetic attractive members are in a one-to-one correspondence to the multiple first magnetic attractive members.
Four first magnetic attractive members and four second magnetic attractive members are provided. The four first magnetic attractive members are disposed at the four corners of the winding housing 110. The magnetic poles of three of the four first magnetic attractive members involved in adsorption are the N pole, and the magnetic pole of the other first magnetic attractive member involved in adsorption is the S pole. The four second magnetic attractive members are disposed at the four corners of the power supply base output member 200. The magnetic poles of three of the four second magnetic attractive members involved in adsorption are the S pole, and the magnetic pole of the other second magnetic attractive member involved in adsorption is the N pole. That is, among the four first magnetic attractive members, three of them have the N pole facing outward and the other has the S pole facing outward; among the four second magnetic attractive members, three of them have the S pole facing outward and the one has the N pole facing outward. This configuration ensures a relative angle between the automatic winding module 100 and the power supply base output member 200 when the two are in adsorption, thereby ensuring the accuracy of the electrical connection.
The first charging assembly 130 includes a first positive electrode charging terminal 131 and a first negative electrode charging terminal 132.
