The functions that can be achieved by the USB interface include providing charging for external devices, U disk data interaction, screen mirroring of mobile phones or game consoles, access to VR devices, etc. To avoid redundant waste of USB interface functions, vehicle manufacturers usually design different vehicle models and configurations for different user groups.

[0003] Since different USB functions require corresponding different interfaces at the tail of their boxes to achieve signal interaction with the vehicle cockpit domain controller, traditional vehicle manufacturers design different rear cover structures and develop multiple sets of molds to cope with different functional interface configurations when planning the USB box function configuration, resulting in waste of mold cost investment and waste of working hours for frequently replacing mold commercial machines. Summary of the Utility Model

[0006] A reserved connector expansion position is provided on the PCB board for installing an expansion connector, a reserved connector relief hole is provided on the USB box housing, and a covering paper is attached to the reserved connector relief hole.

[0007] In an optional embodiment, the electrical signal connector relief hole corresponds to the installation position of the electrical signal connector;

[0008] The reserved connector relief hole is opposite to the position of the reserved connector expansion position.

[0009] In an optional embodiment, the expansion connector includes one or more, and the reserved connector expansion position and the reserved connector relief hole respectively correspond to the expansion connector one by one.

[0010] In an alternative embodiment, the electrical signal connector relief hole and the reserved connector relief hole are both provided on the rear cover of the USB box housing, and are independently arranged between the electrical signal connector relief hole and the reserved connector relief hole, as well as between the reserved connector relief holes.

[0013] In an alternative embodiment, a USB interface panel is connected to the USB box housing, and a light guide plate is installed between the USB interface panel and the USB interface.

[0014] In an alternative embodiment, the USB interface panel is separately provided from the USB box housing and is detachably connected by a clamping member.

[0015] In an alternative embodiment, the masking paper includes a silver elimination dragon sticker for masking the reserved connector relief hole.

[0016] In a second aspect, the present invention provides an automobile, including the USB charging box according to any one of the foregoing embodiments.

[0033] In the description of the present application, it should also be noted that, unless otherwise clearly specified and defined, the terms "arrangement" and "connection" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be directly connected, or indirectly connected through an intermediate medium, and may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0034] The USB charging box in the present application is mainly applied to the in-vehicle USB interface in an automobile. On the basis of the existing low - configuration USB interface, by setting the reserved installation positions for expansion joints and the corresponding reserved hole positions, the re - tooling during the upgrade and configuration is reduced, thereby reducing the mold investment cost and the waste of working hours for replacing the mold - related commercial machines.

[0035] See Figure 1 , in the USB charging box of the present utility model, the main structure includes a USB box housing 1. A PCB board 2 is installed inside the USB box housing 1. An electrical signal connector 3 is installed on the PCB board 2, and an electrical signal connector relief hole 11 is provided on the USB box housing 1;

[0036] The PCB board 2 constitutes the installation basis for the electrical signal connector 3. The electrical signal connector relief hole 11 enables the electrical signal connector 3 to be electrically configured and connected to the outside, so that the electrical signal connector 3 can interact with the vehicle cockpit domain controller.

[0037] The electrical signal connector 3 in the present utility model is specifically a low - configuration USB connector that meets the basic functions or is for primary development, and can meet the basic charging function or the initial usage requirements. When function expansion is required, other functional connectors need to be installed on the existing basis.

[0038] During the configuration process of expanding the existing automotive signal interaction function, different interfaces need to be opened at the tail end - cover part of the USB box housing 1 to achieve the signal interaction of other connectors. By designing different tail end - cover structures to cope with different functional interface configurations, during this process, the waste of mold cost investment and the waste of working hours for frequently replacing the mold - related commercial machines are increased.

[0039] By reserving the installation positions for expansion joints on the PCB board 2 inside the existing USB box housing 1 in the form of, and combining with the structural idea of reserving connector relief holes 12 on the USB box housing 1, the re - tooling of the USB box housing 1 during the existing function expansion is changed to cope with the re - design and processing of the USB box housing 1 during the upgrade and iteration process.

[0040] The reserved positions and relief holes in this application are mainly centered around the uncertain or expandable connectors during function expansion. In the attached drawings of this application, the structure of the expansion structure is not clearly shown. It mainly focuses on the expandable connectors with uncertainty. Specifically, the reserved connector relief hole 12 on the USB box housing 1 and the reserved connector expansion position 21 on the PCB board 2 are described to highlight the convenience of operation when an expandable connector needs to be equipped.

[0041] On the PCB board 2, there is a reserved connector expansion position 21 for installing an expandable connector. On the USB box housing 1, there is a reserved connector relief hole 12. Combined with the covering paper 4 attached to the reserved connector relief hole 12, during function expansion, it is only necessary to tear off the covering paper 4 to connect and install the expandable connector on the PCB board 2, and enable the reserved connector relief hole 12 to conduct signal interaction with the expandable connector.

[0042] In one specific embodiment, the installation position of the electrical signal connector relief hole 11 corresponds to that of the electrical signal connector 3. Through this setting method, the installation and signal interaction of existing connectors can be carried out.

[0043] By setting the reserved connector relief hole 12 on the USB box housing 1 and the reserved connector expansion position 21 on the PCB board 2 in a position-opposite relationship, when the expandable connector is installed on the PCB board 2, the docking installation of the expandable connector and the reserved connector relief hole 12 can be achieved, ensuring the accuracy of the connection of electrical components and structural components during the function expansion and equipment process.

[0044] From the perspective of different function expansions, the expandable connector includes one or more, and the reserved connector expansion position 21 and the reserved connector relief hole 12 respectively correspond to the expandable connector one by one.

[0045] It is possible to expand the electrical signal connector 3 from different functional perspectives, and at the same time enable different expandable connectors to obtain electrical connections on the PCB board 2 and structural installations on the USB box housing 1 respectively.

[0046] To facilitate the structural installation of the USB connector on the USB box housing 1, both the electrical signal connector relief hole 11 and the reserved connector relief hole 12 are provided on the rear cover of the USB box housing 1.

[0047] Furthermore, to distinguish different functions, the electrical signal connector relief hole 11 and the reserved connector relief hole 12 are independently set, enabling the low-voltage power distribution electrical signal connector 3 to achieve its independent function, such as the charging function, and enabling the expanded expandable connector to achieve the functions after upgrade and iteration, such as U disk data interaction, mobile phone or game console screen mirroring, and VR device access.

[0048] Furthermore, on the basis of the independent setting between the electrical signal connector relief hole 11 and the reserved connector relief hole 12, the independent setting between the reserved connector relief holes 12 can independently distinguish the expanded different functions, meet the daily differentiation application, and reduce the mutual interference between different functions.

[0049] In another specific embodiment, for the convenience of insertion, a USB interface 5 is connected to the PCB board 2. The USB interface 5 and the PCB board 2 form the same electrical module of the USB charging box for sharing by the power signal connector 3 and the expansion connector.

[0050] After the USB interface 5 and the PCB board 2 are connected, a shared electrical module can be formed for the common use of different electrical signal connectors 3. The USB interface 5 is mainly used to connect to an external terminal device, while the electrical signal connector 3 connected to the PCB board 2, whether it is a low - configuration electrical signal connector 3, a high - configuration one, or an expansion connector with other functions, is mainly used to connect to other functional electrical devices inside the vehicle.

[0051] By connecting the expansion connector to the PCB board 2, the data interaction equipment can be realized through the shared USB interface 5, enhancing the compactness and compatibility of the overall structure of the USB charging box.

[0052] In this embodiment, the form of the USB interface 5 is not specifically limited. During the configuration process, the USB interface 5 can be configured as a Type - A interface, a Type - B interface, a Type - C interface, a Micro USB interface 5, and / or a Mini USB interface 5 connected to the PCB board 2, and can be set according to the specific application frequency and the interface form of the terminal device.

[0053] From the perspective of the hardware structure connection, the USB box housing 1 is connected with a USB interface panel 6. The PCB board 2, the USB interface 5, and different - function USB connectors are installed between the USB interface panel 6 and the USB box housing 1.

[0054] The front end of the USB interface 5 is installed on the USB interface panel 6. To improve the reliable and stable installation of the USB interface 5 and facilitate insertion, a light guide plate 7 is installed between the USB interface panel 6 and the USB interface 5. The light guide plate 7 can improve the light utilization rate, facilitate accurately judging the position of the USB interface 5 in night vision or insufficient light, and quickly perform the insertion operation.

[0055] Based on the functional expansion of the USB charging box in this application, the USB interface panel 6 and the USB box housing 1 are separately arranged and detachably connected through a snap-in piece. The arrangement of the snap-in piece can form a detachable snap-in connection relationship between the USB interface panel 6 and the USB box housing 1, which is convenient for the disassembly and assembly of the USB charging box, and is conducive to the welding and installation of the expansion joint on the PCB board 2 after the USB interface panel 6 and the USB box housing 1 are separated.

[0056] The covering paper 4 in the utility model includes a silver dragon sticker for covering the reserved joint clearance hole 12. The silver dragon sticker has good wear resistance and scratch resistance, and is widely used in the field of electronic product labels to achieve aesthetics and protection. In the later development, it can be directly torn to expose the reserved joint clearance hole 12, saving the cost and labor time of opening a new mold.

[0057] The utility model also provides a car, including the above-mentioned USB charging box and the vehicle cabin domain controller, which can meet the expansion needs of USB port function configuration with low-cost investment, and reduce the mold cost investment and manufacturing time waste when the USB function configuration is upgraded and iterated with a simplified structural form.

[0058] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.

[0059] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
