Description

Technical Field

[0001] This application relates to the field of charging modules, and more particularly to an in-vehicle magnetic USB charging module and a vehicle. Background Technology

[0002] Today, with the development of automobiles, Type-A or Type-C electrical interfaces are being used more and more widely in cars, and there are more and more wire harnesses or devices plugged into these interfaces. However, Type-A or Type-C interfaces are not able to support heavier electronic devices, especially during car operation when shaking is inevitable. Over time, this can easily lead to wear and tear on the electrical interfaces. Utility Model Content

[0003] This application provides an in-vehicle magnetic USB charging module designed to reduce wear and tear.

[0004] To achieve the above objectives, this application proposes a vehicle-mounted magnetic USB module, including a housing, a cover, a circuit board, and a magnetic component. The housing encloses a receiving cavity, and the housing has a first opening and a second opening communicating with the receiving cavity. The circuit board is disposed in the receiving cavity, and the circuit board is connected to a first electrical interface and a second electrical interface, the first electrical interface extending through the first opening. The cover is connected to the housing and covers the second opening, and the cover has a third opening communicating with the receiving cavity, the second electrical interface extending through the third opening. The magnetic component is disposed in the receiving cavity and connected to the cover.

[0005] In the above technical solution, by setting a magnetic component on the cover, when the second electrical interface is connected to the electronic device, the magnetic component can provide a certain magnetic attraction force to the electronic device, so that the electronic device can be firmly attached to the vicinity of the second electrical interface. This is beneficial to improve the connection stability between the electronic device and the charging module, reduce charging interruption or damage caused by collision or shaking, and reduce friction between the second electrical interface and the electronic device, which is beneficial to extend the service life of the charging module.

[0006] Optionally, the magnetic component is a ring magnet, at least partially surrounding the third opening. For example, the magnetic component includes multiple independent small magnet blocks, and the ring-shaped magnetic component surrounding the third opening can make the magnetic attraction effect more uniform, thereby improving the connection stability between the charging module and the electronic device.

[0007] Optionally, the vehicle-mounted magnetic USB charging module further includes an adhesive layer, through which the magnetic component is connected to the cover. The adhesive layer makes the connection between the magnetic component and the cover more secure, less prone to detachment, improves the connection strength between the magnetic component and the cover, and reduces the risk of separation between the magnetic component and the cover due to collisions or shaking.

[0008] Optionally, the cover is provided with a first snap-fit ​​part, and the housing is provided with a first snap-fit ​​groove. The first snap-fit ​​part extends into the receiving cavity and snaps into the first snap-fit ​​groove. The structure is simple and the cover and housing can be connected without additional tools, making the operation simple and convenient.

[0009] Furthermore, the cover also includes a second snap-fit ​​portion, and the housing also includes a second snap-fit ​​groove. The second snap-fit ​​portion is disposed opposite to the first snap-fit ​​portion. The second snap-fit ​​portion extends into the receiving cavity and snaps into the second snap-fit ​​groove. The two snap-fit ​​portions are disposed opposite to each other, which helps to improve the connection stability between the housing and the cover.

[0010] Furthermore, the first latching portion includes a first hook portion, which bends away from the second latching portion and engages with the first latching groove. The second latching portion includes a second hook portion, which bends away from the first latching portion and engages with the second latching groove. The engagement of at least two latching portions including hook portions with latching grooves ensures a stable connection between the cover and the housing, better withstands the stress of the electronic device, reduces the separation of the cover and housing, and improves the overall structural strength of the charging module.

[0011] Optionally, the vehicle-mounted magnetic USB charging module further includes a magnetic support component connected to the housing. The magnetic support component has a third electrical interface connected to the second electrical interface. The magnetic support component can be a magnetic bracket or magnetic housing for connecting electronic devices. This magnetic support component allows the vehicle-mounted USB charging module to support devices that do not have built-in magnetic functionality, improving the module's versatility.

[0012] Optionally, the housing of the vehicle-mounted USB charging module is cylindrical, which allows for a more uniform stress distribution and a more stable structure.

[0013] Optionally, a fixing plate is provided on the outer surface of the housing.

[0014] Optionally, the cover has an annular groove, and the magnetic component is disposed in the annular groove. The annular groove accommodates the magnetic component, reducing the possibility of the magnetic component becoming loose.

[0015] Secondly, this application also proposes a vehicle that includes the aforementioned vehicle-mounted magnetic USB charging module.

[0016] In this embodiment, the module formed by connecting the shell and the cover can effectively withstand the pressure from some electronic devices. Adding magnetic components can use magnetic force to stably attract some heavier electronic devices. Due to the magnetic force, the vertical stress on the interface will be reduced, which can effectively alleviate the wear of the port.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0036] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0037] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0038] Firstly, this application proposes an in-vehicle magnetic USB charging module, such as... Figure 1 As shown, the vehicle-mounted magnetic USB charging module includes a housing 1, a cover 2, a circuit board 3, and a magnetic component 4.

[0039] For the aforementioned housing 1, please refer to Figures 1 to 3 The housing 1 encloses a receiving cavity 11, and the housing 1 has a first opening 12 and a second opening 13. The first opening 12 and the second opening 13 communicate with the receiving cavity 11, and the first opening 12 and the second opening 13 are disposed opposite to each other at both ends of the housing 1. The circuit board 13 can be placed in the receiving cavity 11 through the second opening 13, and the first opening 12 can be connected to the vehicle USB interface.

[0040] For circuit board 3 mentioned above, please refer to... Figures 1 to 4 The circuit board 3 is disposed within the receiving cavity 11 of the housing 1. The circuit board 3 can be electrically connected to the vehicle power system and can convert the output voltage of the vehicle power system into the standard voltage required by the electronic devices to power the electronic devices. The circuit board 3 includes a first electrical interface 31 and a second electrical interface 32. For example, the first electrical interface 31 and the second electrical interface 32 are disposed opposite to each other at both ends of the circuit board 3. The first electrical interface 31 extends to the first opening 12 and can be connected to the vehicle USB interface, while the second electrical interface 32 is disposed near the second opening 13 for connection to the electronic device interface.

[0041] For the aforementioned cover 2, please refer to Figures 2 to 5The cover 2 is connected to the housing 1 and covers the second opening 13. The cover 2 has a third opening 21 communicating with the receiving cavity 11. The second electrical interface 32 extends into the third opening 21, facilitating connection between the second electrical interface 32 and an electronic device interface. The housing 1 and the cover 2 together provide a physical barrier for the circuit board 3, reducing the entry of dust, debris, liquids, and other impurities into the vehicle-mounted magnetic USB charging module, thereby protecting the various electronic components on the circuit board 3.

[0042] For the magnetic component 4 mentioned above, please refer to... Figure 1 and Figure 6 The magnetic element 4 is disposed in the receiving cavity 11 and connected to the cover 2. In the embodiments of this application, by providing a magnetic element on the cover 2, when the second electrical interface 32 is connected to the electronic device, the magnetic element 4 can provide a certain magnetic attraction force to the electronic device, so that the electronic device can be stably attached near the second electrical interface 32. This is beneficial to improving the connection stability between the electronic device and the vehicle magnetic USB charging module, reducing charging interruption or damage caused by collision or shaking, and reducing friction between the second electrical interface 32 and the electronic device, which is beneficial to extending the service life of the vehicle magnetic USB charging module.

[0043] In some embodiments, such as Figure 6 As shown, the magnetic component 4 includes individual small magnet blocks, and the magnetic component 4 is arranged at least partially around the cover 2. The individual small magnet blocks can be replaced independently when they fail, which enhances the flexibility of the magnetic component 4. The surrounding distribution of small magnet blocks can make the magnetic force distribution uniform and the magnetic attraction performance more stable.

[0044] The magnetic component 4 can be installed on the cover 2 by means of snap-fit, threaded connection, or adhesive bonding. Taking adhesive bonding as an example, in some embodiments, please refer to... Figure 1 The vehicle-mounted magnetic USB charging module also includes an adhesive layer 5. The magnetic component 4 is connected to the cover 2 through the adhesive layer 5, which makes the connection between the magnetic component 4 and the cover 2 more secure and less likely to fall off. This increases the connection strength between the magnetic component 4 and the cover 2 and reduces the possibility of the magnetic component 4 separating from the cover 2 due to collisions or shaking. Furthermore, it facilitates the separation of the magnetic component 4 from the cover 2 when disassembling the magnetic component 4, making it easier to replace and maintain the magnetic component 4.

[0045] In some embodiments, such as Figures 2 to 4 As shown, the cover 2 is provided with a first snap-fit ​​part 22, and the housing 1 is provided with a first snap-fit ​​groove 14. The first snap-fit ​​part 22 extends into the receiving cavity 11 and snaps into the first snap-fit ​​groove 14. The structure is simple, and the cover 2 and housing 1 can be connected without additional tools, making the operation simple and convenient.

[0046] Furthermore, the cover 2 also includes a second snap-fit ​​portion 23, and the housing 1 also includes a second snap-fit ​​groove 15. The second snap-fit ​​portion 23 is disposed opposite to the first snap-fit ​​portion 21, and the second snap-fit ​​portion 23 extends into the receiving cavity 11 and snaps into the second snap-fit ​​groove 15. The two snap-fit ​​portions are disposed opposite to each other, which helps to improve the connection stability between the housing 1 and the cover 2.

[0047] Furthermore, in some embodiments, the first latching portion 22 includes a first hook portion 221, which is bent away from the second latching portion 23 and engages with the first latching groove 14. The second latching portion 23 includes a second hook portion 231, which is bent away from the first latching portion 22 and engages with the second latching groove 15. The engagement of at least two latching portions including hooks with the latching grooves ensures a stable connection between the housing 1 and the cover 2, better withstands the stress of the electronic device, reduces the separation of the housing 1 and the cover 2, and improves the overall structural strength of the vehicle magnetic USB charging module.

[0048] In some embodiments, the vehicle-mounted magnetic USB charging module further includes a magnetic support 6, which is connected to the housing 2. The magnetic support 6 is provided with a third electrical interface 61, which is connected to a second electrical interface 32. This magnetic support 6 can be used by electronic devices that do not have their own magnetic attraction mechanisms, thus enhancing the applicability of the vehicle-mounted magnetic USB charging module.

[0049] In some embodiments, such as Figure 2 and Figure 4 As shown, the shell 1 is cylindrical, and the cover 2 also includes an annular groove 24, within which the magnetic component 4 is disposed. The cylindrical shell 1 ensures uniform load distribution under stress, enhancing the structural stability of the shell 1. The annular groove 24 ensures a stable connection between the magnetic component 4 and the cover 2, reducing displacement that may occur during vehicle movement and enhancing the stability of the magnetic attraction operation of the magnetic component 4.

[0050] In some embodiments, such as Figure 2 As shown, a fixing plate 16 protrudes from the outer surface of the housing 1. For example, the fixing plate 16 is used to connect the entire vehicle magnetic USB module to the vehicle, which can strengthen the connection between the vehicle magnetic USB module and the vehicle USB interface and improve the stability of the vehicle magnetic USB module during vehicle operation.

[0051] On the other hand, this application provides a vehicle that includes the aforementioned vehicle-mounted magnetic USB charging module.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them; under the concept of this application, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this application as described above, which are not provided in detail for the sake of brevity; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
