Technical Field

[0001] This utility model relates to the field of charging equipment technology, and in particular to a magnetic multi-port charging base. Background Technology

[0002] Existing electronic receipt generators and other devices typically use independent charging methods, meaning each device is equipped with a power adapter and charging cable, and is connected for charging via wired plug-and-play. This results in low charging efficiency, an inability to charge multiple devices simultaneously, and the charging dock needs to integrate multiple functions, leading to a large overall size that is difficult to miniaturize and affects space layout.

[0003] Utility model CN221633486U discloses a wireless magnetic charging dock for tablets, comprising a base, an upper shell connected to one side of the top of the base, a main control board installed between the base and the upper shell, a power supply module electrically connected to the main control board, and a power supply connected to a power source at the other end of the power supply module via a wire. Several slots are equidistantly spaced on the top surface of the upper shell, and multiple supports are installed on the upper shell through these slots. While it enables plug-and-play magnetic charging, it relies on extended supports for support and magnetic charging, resulting in a fragmented charging dock with a large overall size, affecting space layout and making it inconvenient to carry and less portable. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a magnetic multi-port charging dock that enables miniaturized magnetic charging of multiple devices, offering high space utilization and portability.

[0005] To achieve the above objectives, this utility model provides a magnetic multi-port charging dock, comprising an upper shell, a lower shell, and an electrical system. The upper shell and the lower shell are detachably connected. The top of the upper shell has multiple charging slots, and the bottom of each charging slot is provided with a magnetic suction element and a metal pin. The electrical system includes a motherboard and a charging module. The motherboard is connected to the upper shell by screws and connected to an external power source via a power cord. The charging module is fixed inside the lower shell and electrically connected to the motherboard. The motherboard is provided with metal contacts electrically connected to the metal pins, for supplying power to the device to be charged through the metal contacts and the metal pins.

[0006] In this invention, multiple charging slots are used to insert multiple devices that need to be charged. The slots themselves can limit the position of the devices to be charged. Integrating the charging slots into the base body makes the base body smaller and the structure more compact. Metal pins are used to electrically connect the charging port of the device to be charged to the metal contacts on the motherboard. Magnetic components are used to provide attraction for the device to be charged, so as to ensure the stability of the device to be charged in the charging slots and prevent poor contact of the metal pins.

[0007] Optionally, the motherboard is provided with a power interface, a switch interface and a charging interface. The power cable is electrically connected to the motherboard through the power interface, and the charging module is electrically connected to the motherboard through the charging interface. A power switch is provided on the top of the upper housing. The power switch is connected to the switch interface on the motherboard and is used to send control signals to the motherboard.

[0008] In this invention, the inclusion of a power interface, a switch interface, and a charging interface enables a modular design of the internal structure of the device, allowing for simpler and more reliable electrical connections.

[0009] Optionally, multiple charging modules and multiple charging interfaces are provided in a one-to-one correspondence, and the multiple charging modules are connected in parallel. Each charging interface corresponds to one or more charging card slots.

[0010] In this invention, multiple charging modules connected in parallel can work independently, reducing the impact of a single charging module failure on the entire charging process and reducing the load on each charging module, thereby extending its service life.

[0011] Optionally, the charging card slot is symmetrical in both the length and width directions, and there are multiple metal pins arranged side by side in the center, wherein the number of metal pins on both sides is the same as the number in the center and the positive and negative electrodes are opposite.

[0012] In this invention, the charging slot is designed as a structure symmetrical in the length and width directions, and multiple metal pins are arranged in the center, so that the device to be charged can be inserted into the charging slot and connect with the multiple metal pins regardless of whether it is upright or not. At the same time, the multiple metal pins on both sides are set as positive or negative poles, and the multiple metal pins in the middle are set as opposite negative or positive poles, so that the device to be charged can correspond to the positive and negative electrodes of the multiple metal pins regardless of whether it is inserted into the charging slot upright or not.

[0013] Optionally, the charging card slot is embedded with a silicone anti-slip sleeve, and the bottom of the silicone anti-slip sleeve is provided with a through hole corresponding to the metal pin.

[0014] In this invention, the silicone anti-slip sleeve can increase the friction with the device to be charged, thereby improving the stability during charging. At the same time, it can prevent the device to be charged from scratching or impacting the upper shell due to direct contact, thus playing a protective role for the device to be charged and the upper shell.

[0015] Optionally, a fixing buckle is integrally formed on the inner bottom wall of the lower housing, and the charging module is engaged with the fixing buckle.

[0016] In this invention, the assembly of the charging module is simpler and faster through the cooperation of the fixing buckle and the charging module, eliminating the need for additional structures to install and fix the charging module, thus reducing production costs. Furthermore, the fixing buckle also elevates the charging module and motherboard, increasing the gap between the charging module / motherboard and the lower housing for better heat dissipation.

[0017] Optionally, the magnetic attractor is a magnet, and there are two magnetic attractors in each charging card slot, with the two magnetic attractors symmetrically arranged on both sides of the metal pin.

[0018] In this invention, by symmetrically arranging two magnets, a more balanced attractive force can be provided to the device to be charged, thereby improving the stability of the device to be charged.

[0019] Optionally, a metal nameplate is provided at the center of the bottom wall of the lower housing, and the metal nameplate and the charging module are located on the inner and outer sides of the bottom wall of the lower housing. Multiple anti-slip pads are arranged in an array on the bottom wall of the lower housing.

[0020] In this invention, the metal nameplate has good thermal conductivity, which can improve the heat dissipation of the charging module, thereby reducing the internal temperature of the device and extending the service life of the electrical components. At the same time, the metal nameplate has a certain weight, which can also lower the center of gravity of the device and improve the stability of the device. The anti-slip pads are used to increase the friction between the device and the contact surface, ensuring that the device remains stable even when subjected to small forces during the charging process.

[0021] Optionally, a cover plate is glued to the surface of the upper housing, and the surface of the cover plate is provided with a plurality of numerical labels, the plurality of numerical labels corresponding one-to-one with the positions of the plurality of charging card slots.

[0022] In this utility model, by corresponding the charging card slots with the numerical labels one by one, it is convenient to locate and place specific devices. At the same time, the cover plate can also play a certain protective role and beautify the appearance of the product.

[0023] Optionally, the upper housing, the lower housing, and the cover plate are all made of ABS V0 grade flame-retardant material.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0037] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0038] See Figure 1 , Figure 2 and Figure 4 According to an embodiment of the present invention, a magnetic multi-port charging dock includes an upper housing 1, a lower housing 2, and an electrical system. The upper housing 1 and the lower housing 2 are detachably connected. The top of the upper housing 1 has multiple charging slots 11. The bottom of each charging slot 11 is provided with a magnetic suction element 12 and a metal pin 13. The electrical system includes a main board 31 and a charging module 32. The main board 31 is connected to the upper housing 1 by screws and is connected to an external power source by a power cord. The charging module 32 is fixed inside the lower housing 2 and electrically connected to the main board 31. The main board 31 is provided with metal contacts 311 electrically connected to the metal pins 13 for supplying power to the device to be charged through the metal contacts 311 and the metal pins 13.

[0039] In this invention, multiple charging slots 11 are used to insert multiple devices that need to be charged. The slots themselves can limit the position of the devices to be charged. Integrating the charging slots 11 into the base body makes the base body smaller and the structure more compact. The metal pins 13 are used to electrically connect the charging port of the device to be charged to the metal contacts 311 on the motherboard 31. The magnetic suction component 12 is used to provide attraction for the device to be charged, so as to ensure the stability of the device to be charged in the charging slots 11 and to prevent poor contact of the metal pins 13.

[0040] Specifically, the end of the device to be charged inserted into the charging slot 11 is made of a material that can be attracted by the magnetic chuck 12, or has a magnet embedded therein that can attract the magnetic chuck 12. The upper housing 1 and the lower housing 2 are detachably connected by screws. Multiple connecting seats are arranged circumferentially inside the lower housing 2, and multiple connecting holes are correspondingly opened circumferentially on the upper housing 1. The inner end of the screw passes through the connecting hole and is threadedly connected to the corresponding connecting seat.

[0041] Specifically, in this utility model, the charging card slots 11 are arranged in two rows on the upper housing 1, with 10 charging card slots 11 in each row, meaning that the device can simultaneously provide charging for up to 20 devices to be charged.

[0042] See Figure 4 In some embodiments of this utility model, the motherboard 31 is provided with a power interface 312, a switch interface 313 and a charging interface 314. The power cord is electrically connected to the motherboard 31 through the power interface 312, and the charging module 32 is electrically connected to the motherboard 31 through the charging interface 314. A power switch 15 is provided on the top of the upper housing 1. The power switch 15 is connected to the switch interface 313 on the motherboard 31 and is used to send control signals to the motherboard 31.

[0043] In this invention, the configuration of the power interface 312, the switch interface 313, and the charging interface 314 enables a modular design of the internal structure of the device, allowing for simpler and more reliable electrical connections.

[0044] Specifically, such as Figure 4 As shown, the charging interface 314 includes a first interface 3141 and a second interface 3142. The charging module 32 is connected to a third interface and a fourth interface. The power interface 312 is connected to the first interface 3141, the first interface 3141 is connected to the third interface, and the fourth interface is connected to the second interface 3142. This allows AC power to be input from the power interface 312 and sequentially enter the charging module 32 through the first interface 3141 and the third interface, where it is converted into DC power that can be used to charge the device. The DC power then sequentially returns to the metal contact 311 of the motherboard 31 through the fourth interface and the second interface 3142.

[0045] See Figure 4 In some embodiments of this utility model, multiple charging modules 32 and multiple charging interfaces 314 are provided in a one-to-one correspondence, and multiple charging modules 32 are connected in parallel. Each charging interface 314 corresponds to one or more charging slots 11.

[0046] In this invention, the multiple charging modules 32 arranged in parallel can work independently, reducing the impact of a single charging module 32 failure on the entire charging process, while also reducing the load on each charging module 32 to extend its service life.

[0047] See Figure 2 In some embodiments of this utility model, the charging card slot 11 is symmetrical in both the length and width directions, and there are multiple metal pins 13 arranged side by side in the center, wherein the number of the multiple metal pins 13 on both sides is the same as the number in the middle and the positive and negative electrodes are opposite.

[0048] In this invention, the charging slot 11 is designed as a structure that is symmetrical in the length direction and width direction, and multiple metal pins 13 are arranged in the center, so that the device to be charged can be inserted into the charging slot 11 and connected with the multiple metal pins 13 regardless of whether it is upright or not. At the same time, the multiple metal pins 13 on both sides are set as positive or negative poles, and the multiple metal pins 13 in the middle are set as opposite negative or positive poles, so that the device to be charged can be inserted into the charging slot 11 regardless of whether it is upright or not and can be connected with the positive or negative electrodes of the multiple metal pins 13.

[0049] Specifically, in this application, each charging slot 11 contains four metal pins 13, with the two metal pins 13 on the left and right sides being positive electrodes and the two metal pins 13 in the middle being negative electrodes, or the two metal pins 13 on the left and right sides being negative electrodes and the two metal pins 13 in the middle being positive electrodes. Therefore, regardless of whether the device to be charged is inserted into the charging slot 11 in the correct orientation, the metal pins 13 on both sides are the same positive and negative electrodes, and the metal pins 13 in the middle are also the same positive and negative electrodes, which greatly improves the convenience of using the device.

[0050] See Figure 1 In some embodiments of this utility model, a silicone anti-slip sleeve 14 is embedded in the charging card slot 11, and a through hole is provided at the bottom of the silicone anti-slip sleeve 14 corresponding to the metal pin 13.

[0051] In this invention, the silicone anti-slip sleeve 14 can increase the friction with the device to be charged, thereby improving the stability during charging. At the same time, it can prevent the device to be charged from scratching or impacting the upper shell 1 due to direct contact, thus playing a protective role for the device to be charged and the upper shell 1.

[0052] See Figure 1In some embodiments of this utility model, a fixing buckle 21 is integrally formed on the inner bottom wall of the lower housing 2, and the charging module 32 is engaged with the fixing buckle 21.

[0053] In this invention, the assembly of the charging module 32 is simpler and faster through the cooperation of the fixing buckle 21 and the charging module 32, and there is no need to install and fix the charging module 32 through other structures, thus reducing production costs. In addition, the fixing buckle 21 also serves to lift the charging module 32 and the motherboard 31, which can increase the gap between the charging module 32 and the motherboard 31 and the lower housing 2, so as to achieve better heat dissipation.

[0054] See Figure 2 In some embodiments of this utility model, the magnetic attractant 12 is a magnet, and there are two magnetic attractants 12 in each charging card slot 11. The two magnetic attractants 12 are symmetrically arranged on both sides of the metal pin 13.

[0055] In this invention, by symmetrically arranging two magnets, a more balanced attractive force can be provided to the device to be charged, thereby improving the stability of the device to be charged.

[0056] See Figure 3 In some embodiments of this utility model, a metal nameplate 22 is provided at the center of the bottom wall of the lower housing 2. The metal nameplate 22 and the charging module 32 are located on the inner and outer sides of the bottom wall of the lower housing 2. A plurality of anti-slip pads 23 are arranged in an array on the bottom wall of the lower housing 2.

[0057] In this invention, the metal nameplate 22 has good thermal conductivity, which can improve the heat dissipation of the charging module 32, thereby reducing the internal temperature of the device and extending the service life of the electrical components. At the same time, the metal nameplate 22 has a certain weight, which can also lower the center of gravity of the device and improve the stability of the device. The anti-slip pads 23 are used to increase the friction between the device and the contact surface, ensuring that the device remains stable even when subjected to small forces during the charging process.

[0058] See Figure 1 In some embodiments of this utility model, a cover plate 4 is glued to the surface of the upper housing 1, and a plurality of numerical labels are provided on the surface of the cover plate 4, and the plurality of numerical labels correspond one-to-one with the positions of the plurality of charging card slots 11.

[0059] In this utility model, by corresponding the charging card slot 11 with the numerical labels one by one, it is convenient to locate and place specific devices. At the same time, the cover plate 4 can also play a certain protective role and beautify the appearance of the product.

[0060] See Figure 1In some embodiments of this utility model, the upper shell 1, the lower shell 2, and the cover plate 4 are all made of ABS V0 grade flame retardant material.

[0061] In this invention, the upper shell 1, lower shell 2 and cover plate 4 made of ABS V0 flame retardant material have good flame retardant and high temperature resistance, which can improve the safety of equipment charging. ABS V0 flame retardant material is an engineering plastic modified by adding flame retardants, which can maintain the original toughness, rigidity and surface hardness of ABS.

[0062] When this utility model is in operation, the power cord is connected to an external power source, and the power switch 15 is pressed to supply power to the motherboard 31. The device to be charged is inserted into the charging slot 11, and the magnetic suction piece 12 at the bottom of the charging slot 11 automatically attracts the device to be charged, so that the charging contacts on the device to be charged are tightly attached to the outer end of the metal pin 13. At the same time, the inner end of the metal pin 13 is electrically connected to the metal contact 311 on the motherboard 31. The motherboard 31 distributes the power from the external power source to the charging module 32 through the charging interface 314. The charging module 32 converts the current into the power required by the device to be charged and outputs it to the device to be charged through the metal contact 311 for charging. When the power is fully charged, the device can be removed from the charging slot 11 by providing a force greater than the magnetic attraction force. The silicone anti-slip sleeve 14 prevents scratches. When all devices are fully charged and removed, the power switch 15 is turned off.

[0063] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
