Description

Technical Field

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

[0002] Amid the rapid development of the new energy transportation industry, low-power charging piles, as an important component of basic energy replenishment infrastructure for electric vehicles, are seeing continuous expansion in deployment and increasingly diversified application scenarios. Currently, low-power charging piles are widely used in various settings, including personal garages, community streets, commercial parking lots, and even underground spaces, placing higher demands on their environmental adaptability and installation flexibility. Installation methods are evolving from traditional expansion bolt fixing and concrete foundation pouring to more convenient modular assembly and point-contact supports that minimize damage to the original structure. The market not only pursues installation efficiency and cost optimization but also increasingly values ​​the overall experience for end-users and property owners.

[0003] However, existing low-power charging piles still have significant limitations when dealing with complex installation environments. On the one hand, most products still rely on pre-set installation interfaces or uniform base designs, making it difficult to adapt to diverse substrates such as asphalt roads, concrete foundations, tiled floors, iron platforms, and even walls. On the other hand, the installation process often requires specialized tools and considerable manual adjustments, lacking systematic solutions for anti-slip, rust prevention, and insulation treatment of iron surfaces, as well as reliable fixing between different materials. This leads to frequent problems in actual deployment, such as a lack of compatible parts, unstable installation, insufficient durability, or poor visual coordination, limiting the rapid expansion of charging networks and the improvement of user experience.

[0004] Therefore, there is an urgent need to develop a low-power charging pile installation structure that can flexibly adapt to various base materials and installation conditions. While ensuring installation convenience and reliability, it is also necessary to improve its comprehensive adaptability to complex environments (especially conventional foundations and metal surfaces), thereby promoting the integration of charging infrastructure into urban and community spaces in a more efficient and human-centered manner.

[0025] Please see Figure 1This application provides a magnetic charging pile 10 according to one embodiment. The magnetic charging pile 10 includes: a control module 100, a housing 200, an electromagnetic induction device 300, a magnetic device 400, and a mounting bracket 500. The control module 100 is fixed inside the housing 200, and the housing 200 has a first mounting plate. The electromagnetic induction device 300 is assembled inside the housing 200 and is located between the control module 100 and the first mounting plate. The electromagnetic induction device 300 is connected to the control module 100. The magnetic device 400 is disposed on the side of the first mounting plate away from the control module 100, and along a direction perpendicular to the first mounting plate, the projection of the magnetic device 400 on the first mounting plate at least partially overlaps with the projection of the electromagnetic induction device 300 on the first mounting plate. The magnetic device 400 is fixed to the mounting bracket 500, which is disposed on the side of the first mounting plate away from the control module 100.

[0026] In some embodiments, the housing 200 is a hollow structure with an accommodating space, and the control module 100 is fixed inside it. The method by which the control module 100 is fixed inside the housing 200 is not limited, as long as the control module 100 and the housing 200 are securely connected. In some embodiments, the control module 100 can be fixed inside the housing 200 with screws. Specifically, the control module 100 is fixed to a pre-set mounting post inside the housing 200 with screws, the screws passing through mounting holes on the control module 100 and threadedly connected to the mounting post, thereby achieving a detachable fixation between the control module 100 and the housing 200, facilitating subsequent maintenance and repair. In some embodiments, the control module 100 can also be fixed inside the housing 200 with clips. In some embodiments, the housing 200 has a first mounting plate, which can be a side wall of the housing.

[0027] In some embodiments, the method by which the electromagnetic induction device 300 is assembled within the housing 200 is not limited, as long as the electromagnetic induction device 300 is fixed to the housing 200. In some embodiments, the electromagnetic induction device 300 can be embedded into the first mounting plate of the housing 200. The electromagnetic induction device 300 can also be fixed to the first mounting plate of the housing 200 by means of snap-fit.

[0028] In some embodiments, the connection method between the electromagnetic induction device 300 and the control module 100 is not limited, as long as the control module 100 can control the current of the electromagnetic induction device 300. In some embodiments, the electromagnetic induction device 300 and the control module 100 can be electrically connected via a wire. Specifically, the material of the wire is not limited; for example, the wire can be made of a metal with good conductivity such as aluminum or copper. In some embodiments, the electromagnetic induction device 300 can be electrically connected to the control module 100 via a circuit connector.

[0029] In some embodiments, the magnetic device 400 (e.g., a permanent magnet array or a magnetically conductive metal sheet) is disposed on the outer side of the first mounting plate (i.e., the side away from the control module 100). Viewed from a direction perpendicular to the first mounting plate, the orthographic projection of the magnetic device 400 onto the first mounting plate overlaps with, at least partially, the orthographic projection of the electromagnetic induction device 300 onto the first mounting plate. This arrangement ensures that the electromagnetic induction device 300 can effectively sense changes in magnetic force with the magnetic device 400.

[0030] In some embodiments, the method by which the magnetic device 400 is fixed to the bracket 500 is not limited, as long as the magnetic device 400 and the bracket 500 are securely fixed. In some embodiments, the magnetic device 400 can be fixed to the bracket 500 with screws. The magnetic device 400 can also be fixed to the bracket 500 by adhesive, clips, or other methods. The bracket 500 is located on the outer side of the first mounting plate.

[0031] In some embodiments, the magnetic charging pile 10 can be installed on a cement or other wall surface using the bracket 500. For example... Figure 2 As shown, the bracket 500 can be fixed to the wall 101 with screws. In some embodiments, the bracket 500 can be omitted, and the magnetic charging pile 10 can be directly installed on the iron surface. When installed on a magnetic iron surface, the magnetic charging pile 10 can be directly placed in a suitable position on the magnetic iron surface.

[0032] In this embodiment, the magnetic device 400 and the bracket 500 work together to install the device on either a wall or an iron surface, which greatly improves the device's adaptability to complex environments while ensuring convenient and reliable installation.

[0033] In some embodiments, the control module 100 includes a circuit board, such as Figure 3As shown, the circuit board integrates a control chip (such as an MCU), a communication module, and a power conversion circuit. The power conversion circuit converts the AC mains power input to the input terminals into the DC power required by the device. Typical electronic components it includes include: a transformer (for stepping down the voltage), a rectifier bridge (for rectifying AC into pulsating DC), a filter capacitor (for smoothing the waveform), and a voltage regulator chip (for outputting a stable DC voltage). In some embodiments, the circuit board is fixed to the housing 200 with screws.

[0034] In some embodiments, the electromagnetic induction device 300 includes an electromagnetic coil, and the first mounting plate has a groove on the side facing the control module 100, in which the electromagnetic coil is fitted. In some embodiments, the first mounting plate has a circular or square groove on the side facing the control module 100, and the electromagnetic induction device 300 is preferably an electromagnetic coil, which is embedded and fixed in the groove to achieve a compact layout.

[0035] In some embodiments, when the magnetic charging pile 10 is powered on, the control module 100 begins to continuously or periodically detect the current flowing through the electromagnetic induction device 300 (electromagnetic coil). This current value has a defined correspondence with the magnetic attraction force (magnetic force value) generated between the electromagnetic coil and the external magnetic device 400 (which can be obtained through pre-calibration). The processor inside the control module 100 calculates the current actual magnetic force value based on the detected current value using a pre-stored algorithm or a lookup table method.

[0036] In some embodiments, the control module 100 compares the calculated actual magnetic force value with a preset threshold. If the comparison result shows that the actual magnetic force value is less than the preset threshold, the control module 100 determines that the current magnetic attraction force is insufficient and there is a safety risk. At this time, the control module 100 can immediately send a safety alarm signal to the user-bound smart terminal device (such as a mobile APP) through its internal wireless communication module (such as Wi-Fi or Bluetooth). After receiving the alarm signal, the smart terminal device will issue a safety alarm by displaying warning information on the screen, emitting an audible alarm, or vibrating, etc., to promptly remind the user to take action.

[0037] In some embodiments, the control module 100 is further configured to receive a magnetic target value sent by the smart terminal device, and adjust the current flowing through the electromagnetic induction device 300 according to the magnetic target value. Specifically, the user can send a magnetic target value to the magnetic charging pile 10 through an application (APP) on the smart terminal device according to the weight of different devices or personal usage preferences.

[0038] The control module 100 receives the target magnetic force value via a communication module. Based on the received target magnetic force value, the control module 100 dynamically adjusts the current flowing through the electromagnetic induction device 300 by regulating the drive circuit (such as an H-bridge circuit) output to the electromagnetic induction device 300. Increasing the current strengthens the magnetic force, while decreasing the current weakens the magnetic force, thus achieving stepless, remotely adjustable magnetic attraction.

[0039] In some embodiments, to enhance electrical safety and prevent leakage or short circuit, the magnetic charging pile 10 further includes an insulating film 600. The insulating film 600 is attached to the side of the first mounting plate away from the control module 100, and the insulating film 600 is disposed between the first mounting plate and the magnetic device 400, serving as insulation and isolation.

[0040] In some embodiments, the method by which the insulating film 600 is attached to the first mounting plate is not limited, as long as the insulating film 600 is fixed to the first mounting plate. In some embodiments, the insulating film 600 can be adhered to the first mounting plate with adhesive, wherein the adhesive can be 3M-5925 adhesive.

[0041] Please see Figure 4 Another embodiment of this application provides a charging system 20, which includes a magnetic charging pile 10 as described in any of the above embodiments and a smart terminal device 11. The smart terminal device 11 is communicatively connected to the control module 100. In some embodiments, the smart terminal device 11 may be a mobile phone, computer, smartwatch, or other device. The device installation information of the magnetic charging pile 10 can be read from the smart terminal device 11 and fed back to the user for real-time monitoring.

[0042] In some embodiments, the smart terminal device 11 is used to acquire the magnetic force value sent by the control module 100 and determine whether to issue a safety alarm based on the magnetic force value. Specifically, the user can send a target magnetic force value to the magnetic charging pile 10 through an application (APP) on the smart terminal device, based on the weight of different devices or personal usage preferences. The control module 100 receives the target magnetic force value through a communication module. Based on the received target magnetic force value, the control module 100 dynamically adjusts the current flowing through the electromagnetic induction device 300 by adjusting the drive circuit (such as an H-bridge circuit) output to the electromagnetic induction device 300. An increase in current strengthens the magnetic force, and a decrease in current weakens the magnetic force, thereby achieving stepless and remotely adjustable magnetic attraction force.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
