Description

Technical Field

[0001] This application relates to the field of charging equipment technology, and in particular to a magnetic charging stand. Background Technology

[0002] With the widespread use of electronic devices, the frequency of use of charging interfaces is increasing. Traditional charging interfaces (such as conventional USB interfaces) mostly use plug-and-play mechanical connections. Frequent plugging and unplugging can easily cause interface wear and poor contact, seriously affecting the stability and lifespan of charging and data transmission. In addition, traditional interfaces require precise alignment when connecting, which is extremely inconvenient in special scenarios such as in-vehicle environments or with sports equipment, where one-handed operation or limited visibility is required. Moreover, the lack of magnetic assistance in the connection method makes it easy for the interface to detach due to external force, interrupting charging or data transmission, resulting in a poor user experience. At the same time, some charging interfaces lack comprehensive optimization in terms of material selection and structural design for connection stability, electromagnetic compatibility, and environmental adaptability, making it difficult to meet users' high requirements for ease of operation and connection reliability.

[0003] Existing charging docks lack a magnetically-based structure for quick alignment and stable connection, resulting in inconvenient plugging and unplugging operations, low connection reliability, and short service life. Furthermore, they are deficient in terms of conductivity, structural strength, protective performance, environmental friendliness of materials, and electrical compatibility, making it impossible to simultaneously meet the comprehensive requirements of "convenient operation, stable connection, efficient conductivity, and adaptability to complex scenarios".

[0004] In response to the aforementioned technologies, there is a need to design a magnetic charging dock that is easy to operate, has a good sealing effect, and can be quickly aligned. Utility Model Content

[0005] The purpose of this application is to provide a magnetic charging dock that has the advantages of stable connection, good sealing effect and quick alignment, and solves the problems of interface wear, poor contact, difficulty in quick alignment and poor sealing effect caused by long-term frequent plugging and unplugging.

[0006] The magnetic charging dock provided in this application adopts the following technical solution: A magnetic charging dock includes a female dock body, on which a circuit assembly for power supply is provided, a terminal block is provided inside the female dock body, a sealing surface is provided outside the circuit assembly, one end of the circuit assembly is electrically connected to a wire card terminal, a magnetic structure is fitted on the female dock body, the magnetic structure includes an N pole magnet and an S pole magnet, and a male connector is magnetically provided on one side of the female dock body.

[0007] By adopting the above technical solution, the female connector body, as the basic load-bearing component of the entire charging dock, integrates core functional modules such as power supply, magnetic attraction, and connection, providing a mounting base for other components. The circuit component is the data transmission channel, with one end forming a stable electrical connection with the female connector body through the terminal block, and the other end connecting to the line card terminal to ensure effective transmission of current and signals. The terminal block is embedded inside the female connector body, serving as the electrical connection medium between the circuit component and the female connector body, ensuring reliable contact and stable resistance. The sealing surface, covering the outside of the circuit component, is a key structure for ensuring the protective performance of the charging dock, preventing external moisture, dust, and other impurities from entering the circuit component and avoiding short circuits or corrosion. The line card terminal serves as the connection interface between the circuit component and external devices, and its structure must match universal wiring standards to ensure convenient plugging and unplugging and stable electrical connection. The magnetic attraction structure adopts a combination design of N-pole magnets and S-pole magnets, utilizing the magnetic property of "opposite poles attracting each other" to achieve rapid positioning and stable adsorption of the female connector body and the male connector. When the male connector approaches the female connector body, the magnetic force of the magnetic attraction structure automatically guides the male connector to correct its position and complete precise docking, solving the problems of difficult alignment and easy wear of traditional plug-in interfaces.

[0008] Preferably, the line assembly includes a D+ line and a D- line for data transmission, and the line assembly also includes a GND line and a VBUS line for grounding.

[0009] By adopting the above technical solution, the line components take into account both power supply capacity and data transmission efficiency. The D+ and D- lines are differential signal lines and are the core channels for data transmission. The GND line is the grounding line, which can conduct the equipment casing or redundant current to the ground, avoiding damage to the equipment and users caused by static electricity or leakage, and improving the safety of use. The VBUS line is the positive power line and undertakes the main function of power transmission.

[0010] Preferably, the other end of the circuit assembly is electrically connected to the terminal block, and the length of the circuit assembly is one meter. The circuit assembly uses 24AWG VBUS wire and GND wire, and the D+ and D- wires use 28AWG wire.

[0011] By adopting the above technical solution, this size offers flexibility and reasonable wiring. Too short a length will limit the installation position of the female connector, while too long a length may lead to wire tangling, signal attenuation, or poor heat dissipation. The specifications of the circuit components result in a smaller data transmission current, and the thin wires can reduce the space occupied by the circuit, improve the overall structural compactness, and reduce signal interference.

[0012] Preferably, the magnetic attraction structure uses N52 neodymium iron boron magnets with a surface magnetic force of 3600 Gauss or more, which achieves rapid alignment and adsorption connection with the male connector through magnetic attraction.

[0013] By adopting the above technical solution, the magnetic attraction enables the male head and female body to be quickly aligned and stably attached, allowing for convenient operation with one hand.

[0014] Preferably, the surface of the N52 neodymium iron boron magnet in the magnetic attraction structure is treated with a three-layer nickel-copper-nickel plating process and is axially magnetized.

[0015] By adopting the above technical solution, the strong magnetic force of N52 neodymium iron boron magnets is utilized, and the connection is not easily broken due to accidental contact with external forces, thus ensuring the continuity of charging and data transmission.

[0016] Preferably, the female connector body is made of nylon material, and the terminals inside the female connector body are made of copper.

[0017] By adopting the above technical solutions, the female connector body ensures insulation performance and structural strength, and the copper terminal blocks of the female connector body improve conductivity.

[0018] Preferably, the sealing surface is provided with a silicone waterproof sleeve structure, the mating area between the sealing surface and the circuit assembly is four centimeters, and the silicone waterproof sleeve structure of the sealing surface simultaneously forms a sealed fixation with the female connector body and the wire clamp terminal.

[0019] By adopting the above technical solution, the female seat body is equipped with a sealing surface structure, which enhances its dustproof and waterproof performance and expands its application scenarios.

[0020] Preferably, the line spacing of the female connector body is 2.54 mm, and the surface of the female connector body and the circuit assembly is free of burrs, shrinkage, flow marks, ripples, silver streaks, surface peeling and bubbles.

[0021] By adopting the above technical solution, the spacing between the lines is fixed, so that the lines will not come into contact with each other and affect each other. At the same time, the absence of burrs can prevent scratches to operators or other parts during assembly.

[0022] In summary, this application includes at least one of the following beneficial technical effects: This magnetic charging dock uses a magnetic structure to easily and stably connect the female connector and male plug. Utilizing the strong magnetic force of N52 neodymium iron boron magnets, it achieves quick alignment and stable adhesion between the male and female connectors, allowing for convenient one-handed operation (especially suitable for poor visibility or special scenarios). Once connected, it is not easily detached due to external force, ensuring continuous charging and data transmission. Secondly, the nylon female connector offers excellent insulation, wear resistance, and impact resistance, significantly extending product lifespan. Copper terminals and appropriately sized cables effectively reduce conductive losses, improve charging and data transmission efficiency, and reduce heat generation. The sealed surface structure enhances dust and water resistance, making it suitable for humid and outdoor environments. The product's raw materials and accessories meet environmental and electrical management requirements, improving electromagnetic compatibility and environmental adaptability, ensuring compatibility with more devices and meeting industry standards. Finally, strict control of key dimensions ensures the accuracy of the male and female connector connection, further enhancing connection stability and reliability. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0026] Example 1: A magnetic charging dock, as shown in the figure. Figure 1 , Figure 2 and Figure 3 The device includes a female connector body 1, a power supply circuit assembly 2 on the female connector body 1, a terminal block 3 inside the female connector body 1, a sealing surface 4 on the outside of the circuit assembly 2, a wire clip terminal 5 electrically connected to one end of the circuit assembly 2, a magnetic attraction structure 6 fitted on the female connector body 1, the magnetic attraction structure 6 including an N pole magnet 601 and an S pole magnet 602, and a male connector 7 magnetically attracted on one side of the female connector body 1.

[0027] By adopting the above technical solution, the female connector body 1, as the basic load-bearing component of the entire charging dock, integrates core functional modules such as power supply, magnetic attraction, and connection, providing a mounting base for other components. The circuit assembly 2 serves as the data transmission channel, with one end forming a stable electrical connection with the female connector body 1 via the terminal block 3, and the other end connecting to the line card terminal 5, ensuring effective transmission of current and signals. The terminal block 3 is embedded inside the female connector body 1, serving as the electrical connection medium between the circuit assembly 2 and the female connector body 1, ensuring reliable contact and stable resistance. The sealing surface 4, covering the outside of the circuit assembly 2, is a key structure ensuring the protective performance of the charging dock. To prevent external moisture, dust, and other impurities from entering the circuit component 2 and avoid short circuits or corrosion, the line card terminal 5 serves as the connection interface between the circuit component 2 and external devices. Its structure must match the universal wiring standard to ensure convenient plugging and unplugging and stable electrical connection. The magnetic structure 6 adopts a combination design of N-pole magnet 601 and S-pole magnet 602. Utilizing the magnetic property of "opposite poles attract each other", it realizes the rapid positioning and stable adsorption of the female connector body 1 and the male connector 7. When the male connector 7 is close to the female connector body 1, the magnetic force of the magnetic structure 6 will automatically guide the male connector 7 to correct its position and complete the precise docking, solving the problems of difficult alignment and easy wear of traditional plug-in interfaces.

[0028] Example 2: A magnetic charging dock, as shown in the figure. Figure 4 and Figure 5Line assembly 2 includes D+ line 201 and D- line 202 for data transmission, and GND line 203 and VBUS line 204 for grounding. Line assembly 2 balances power supply capacity and data transmission efficiency. D+ line 201 and D- line 202 are differential signal lines and are the core channels for data transmission. GND line 203 is a grounding wire that can conduct the equipment casing or redundant current to the ground, preventing damage to the equipment and users caused by static electricity or leakage, and improving safety. VBUS line 204 is the positive power line and undertakes the main function of power transmission. The other end of line assembly 2 is electrically connected to terminal 3. The length of line assembly 2 is one meter. Line assembly 2 uses 24AWG VBUS wire 204 and GND wire 203, while D+ wire 201 and D- wire 202 use 28AWG. This size allows for flexibility and reasonable wiring. If the length is too short, it will limit the installation position of the female connector 1; if it is too long, it may cause wire tangling, signal attenuation, or poor heat dissipation. The specifications of line assembly 2 result in a smaller data transmission current. The thin wires reduce the space occupied by the wires, improve the overall structural compactness, and reduce signal interference. The magnetic attraction structure 6 uses N52 neodymium iron boron magnets with a surface magnetic force of over 3600 Gauss, which are used for magnetic attraction. The magnetic attraction mechanism enables quick alignment and magnetic connection between the male connector 7 and the female connector body 1. This allows for convenient one-handed operation (especially suitable for situations with poor visibility or special scenarios). The N52 neodymium iron boron magnet in the magnetic structure 6 features a three-layer nickel-copper-nickel plating treatment and is axially magnetized. Utilizing the strong magnetic force of the N52 neodymium iron boron magnet, the connection is unlikely to detach due to accidental external contact, ensuring continuous charging and data transmission. The female connector body 1 is made of nylon, and the terminals 3 inside are made of copper. The female connector body 1 ensures insulation performance and structural strength, while the copper terminals improve conductivity. The sealing surface 4 is equipped with a silicone waterproof sleeve structure. The mating area between the sealing surface 4 and the circuit assembly 2 is 4 cm. The silicone waterproof sleeve structure of the sealing surface 4 also forms a sealed fixation with the female body 1 and the wire clamp terminal 5. The female body 1 is equipped with the sealing surface 4 structure to enhance dustproof and waterproof performance and expand the application scenarios (such as humid and outdoor environments). The wire spacing of the female body 1 is 2.54 mm. The surfaces of the female body 1 and the circuit assembly 2 are free of burrs, shrinkage, flow marks, ripples, silver lines, surface peeling and bubbles. The fixed wire spacing prevents the wires from contacting each other and affecting each other. At the same time, the absence of burrs can prevent scratches to operators or other parts during assembly.

[0029] The implementation principle of this application embodiment is as follows: First, the female connector body 1, as the basic load-bearing component of the entire charging dock, integrates core functional modules such as power supply, magnetic attraction, and connection, providing a mounting base for other components. The circuit assembly 2 is the data transmission channel, with one end forming a stable electrical connection with the female connector body 1 through the terminal block 3, and the other end connecting to the line card terminal 5 to ensure effective transmission of current and signals. The terminal block 3 is embedded inside the female connector body 1, serving as the electrical connection medium between the circuit assembly 2 and the female connector body 1, ensuring reliable contact and stable resistance. The sealing surface 4, covering the outside of the circuit assembly 2, is a key structure for ensuring the protective performance of the charging dock, preventing external moisture, dust, and other impurities from entering the circuit assembly 2 and avoiding short circuits or corrosion. The line card terminal 5 serves as the connection interface between the circuit assembly 2 and external devices, and its structure must match universal wiring standards to ensure convenient plugging and unplugging and stable electrical connection. Secondly, the female connector body 1 in this device is injection molded from nylon material, with copper terminal blocks 3 embedded inside. The circuit assembly 2 is composed of 24AWG VBUS wire 204, GND wire 203 and 28AWG D+ wire 201, D- wire 202, with a structure of 24AWG×2C+28AWG×2C and a length of one meter. One end is electrically connected to the terminal block 3 and the other end is connected to the wire clip terminal 5. The silicone waterproof sleeve of the sealing surface 4 is wrapped around the outside of the circuit assembly 2 and sealed and fixed with the female connector body 1 and the wire clip terminal 5. The N52 neodymium iron boron magnet of the magnetic attraction structure 6 is plated with three layers of nickel, copper and nickel, and axially magnetized and embedded on the female connector body 1 to achieve magnetic connection with the male connector 7. Finally, during use, the N52 neodymium iron boron magnet of the magnetic structure 6 is quickly aligned and attracted to the male connector 7 for connection. The circuit assembly 2 is powered through the VBUS line 204 and the GND line 203, and data is transmitted through the D+ line 201 and the D- line 202. The silicone waterproof sleeve of the sealing surface 4 effectively blocks external moisture, ensuring stable use of the charging dock in humid and other complex environments. The surfaces of the female connector body 1 and the circuit assembly 2 are free of burrs, shrinkage, flow marks, ripples, silver lines, surface peeling, and bubbles. The wire spacing is fixed, so that the wires will not come into contact with each other and affect each other. At the same time, the absence of burrs can prevent scratches to operators or other parts during assembly.
