[0002] With the continuous development of vehicle technology, higher and higher requirements are placed on the convenience and safety of vehicle use. For example, head up display (HUD) (or head-up display system) has been widely used in vehicles. The HUD device is a device that projects the vehicle's instrument information (such as speed, rotation speed, temperature, fuel level, etc.) and navigation information to the front of the driver's field of vision. The driver can see the vehicle's instrument information and navigation information in front of the field of vision, without having to look down at the instrument panel or central control display under the steering wheel, thereby improving the braking reaction time in emergency situations and improving driving safety and convenience.

[0003] Currently, HUD devices usually use highly customized shells, and different car companies or different models have different requirements for the type and location of HUD external interfaces, resulting in different shapes of HUD shells. In addition, the HUD shells need to be repeatedly designed and molded to meet the different requirements for the type and location of HUD external interfaces, and the adaptability is poor. Summary of the invention

[0004] The embodiments of the present application provide a switching device, a HUD shell, a HUD device, a HUD system and a mobile terminal, which can realize the sharing of the HUD shell by different models of mobile terminals (such as vehicles), and according to different requirements for the type and position of the HUD external interface, there is no need to repeatedly design and open the mold of the HUD shell, thereby improving adaptability.

[0005] In a first aspect, an embodiment of the present application provides a switching device, which is used to be installed on a HUD housing, and the HUD housing includes a first interface; the switching device includes:

[0006] A second interface and a third interface;

[0007] Among them, at least one of current and image signal is transmitted between the second interface and the first interface, and at least one of current and image signal is transmitted between the third interface and the second interface.

[0008] In an embodiment of the present application, a switching device is provided, which relates to the field of HUD technology, and can be specifically installed on a HUD shell, and the switching device includes a second interface and a third interface. Among them, at least one of current and image signal is transmitted between the second interface and the first interface on the HUD shell. It can be understood that only current is transmitted between the second interface and the first interface, and correspondingly, the first interface is a first power interface, and the second interface is a second power interface; or, only image signal is transmitted between the second interface and the first interface, and correspondingly, the first interface is a first signal interface, and the second interface is a second signal interface; or, the second interface and the first interface support simultaneous transmission of current and image signal. At least one of current and image signal is transmitted between the third interface and the second interface, and it can be understood that only current is transmitted between the third interface and the second interface, and correspondingly, the second interface is a second power interface, and the third interface is a third power interface; or, only image signal is transmitted between the third interface and the second interface, and correspondingly, the second interface is a second signal interface, and the third interface is a third signal interface; or, the third interface and the second interface support simultaneous transmission of current and image signal.

[0009] Current HUD devices usually use highly customized shells, and different mobile terminal (such as vehicles) models have different requirements for the type and location of the HUD external interface, resulting in different HUD shell shapes. In addition, the HUD shell needs to be repeatedly designed and molded to meet the different requirements for the type and location of the HUD external interface, and the adaptability is poor. For example, for a highly customized HUD shell that includes a first interface, if a device or system that needs to be connected to the HUD system in a certain vehicle model supports a third interface, because the first interface cannot adapt to the third interface, the HUD shell cannot meet the needs of a certain vehicle model for the third interface. At this time, the HUD shell needs to be repeatedly designed and molded to enable the HUD shell to have the function of supporting the third interface type, resulting in the problem of repeated design and mold opening of the HUD shell and poor adaptability.

The HUD shell includes a clamping position, which can be specifically used for fixing an adapter installed on the HUD shell. The adapter can refer to the adapter described in the first aspect or any possible implementation manner of the first aspect, which will not be repeated here.

[0037] Current HUD devices usually use highly customized shells, and different mobile terminal (such as vehicles) models have different requirements for the type and location of the HUD external interface, resulting in different HUD shell shapes. In addition, the HUD shell needs to be repeatedly designed and molded to meet the different requirements for the type and location of the HUD external interface, and the adaptability is poor. For example, for a highly customized HUD shell that includes a first interface, if a device or system that needs to be connected to the HUD system in a certain vehicle model supports a third interface, because the first interface cannot adapt to the third interface, the HUD shell cannot meet the needs of a certain vehicle model for the third interface. At this time, the HUD shell needs to be repeatedly designed and molded to enable the HUD shell to have the function of supporting the third interface type, resulting in the problem of repeated design and mold opening of the HUD shell and poor adaptability.

[0038] In the embodiment of the present application, by installing the adapter on the HUD shell, current and / or image signals are transmitted between the second interface of the adapter and the first interface of the HUD shell, and current and / or image signals are transmitted between the second interface of the adapter and the third interface of the adapter.

Specifically, the type of the fifth interface is different from the type of the third interface of the adapter device. In this scenario, the adapter device can be installed on the HUD shell to expand the functions of the interface types that are not supported by the original HUD shell, thereby achieving the need to repeatedly design and open a mold for the HUD shell and meeting the demand for the third interface.

[0047] In a possible implementation manner, the type of the fifth interface is the same as the type of the first interface of the HUD shell.

[0048] In an embodiment of the present application, a possible specific implementation of the type relationship between the fifth interface and the first interface is provided, specifically, the type of the fifth interface of the HUD shell is the same as the type of the first interface of the HUD shell.

In addition, the HUD shell needs to be repeatedly designed and molded to meet the different requirements for the type and location of the HUD external interface, and the adaptability is poor. For example, for a highly customized HUD shell that includes a first interface, if a device or system that needs to be connected to the HUD system in a certain vehicle model supports a third interface, because the first interface cannot adapt to the third interface, the HUD shell cannot meet the needs of a certain vehicle model for the third interface. At this time, the HUD shell needs to be repeatedly designed and molded to enable the HUD shell to have the function of supporting the third interface type, resulting in the problem of repeated design and mold opening of the HUD shell and poor adaptability.

[0074] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0075] The terms "first" and "second" in the specification, claims and drawings of this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0076] The "embodiment" mentioned in this article means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It can be explicitly and implicitly understood by those skilled in the art that in the various embodiments of the present application, if there is no special explanation and logical conflict, the terms and / or descriptions between the various embodiments are consistent and can be referenced to each other, and the technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationships.

[0077] It should be understood that in the present application, "at least one (item)" means one or more, "more than one" means two or more, "at least two (items)" means two or three and more than three, and "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0078] As described in the background technology section, current HUD devices usually use highly customized shells, and different car companies or different models have different requirements for the type and location of the HUD external interface, resulting in different HUD shell shapes, and the HUD shell needs to be repeatedly designed and molded for different requirements for the type and location of the HUD external interface, which has poor adaptability. The present application provides a switching device, a HUD shell, a HUD device, a HUD system and a mobile terminal, which relate to the field of HUD technology, and can achieve the sharing of HUD shells for different mobile terminal (such as vehicles) models, and there is no need to repeatedly design and mold the HUD shell for different requirements for the type and location of the HUD external interface, thereby improving adaptability.

[0079] In order to more clearly describe the solution of the present application, some knowledge related to HUD is first introduced below.

[0080] Head up display (HUD), also known as head-up display system, refers to a multifunctional instrument panel centered on the vehicle driver and operated blindly. The HUD device projects the vehicle's instrument information (such as speed, rotation speed, temperature, fuel level, etc.) and navigation information to the front of the driver's field of vision. The driver can see the vehicle's instrument information and navigation information in front of the field of vision without looking down at the instrument panel or central control display under the steering wheel, thereby improving the braking reaction time in emergency situations and improving driving safety and convenience.

[0081] Combine the following Figures 1A to 1C An application scenario of HUD is described.

[0082] See also Figures 1A to 1C , Figure 1A A schematic diagram of an application scenario of a projection device 100 provided in an embodiment of the present application in the automotive field is shown. Figure 1B A schematic diagram showing another perspective of an application scenario of a projection device 100 provided by an embodiment of the present application in the automotive field, Figure 1C FIG. 1 shows an imaging schematic diagram of a projection device 100 provided in an embodiment of the present application projecting an image into the driver's eyes in the automotive field, which shows Figure 1A and Figure 1B The projection device 100 projects the image into the driver's eyes so that the driver can see the virtual image information.

[0083] Depend on Figures 1A to 1C It can be seen that when the driver looks out of the car through the windshield 200, he can see a virtual image with a certain depth of field (i.e., the distance of the clear image presented in the range before and after the image focus). Among them, the information in front of the car is obtained through information acquisition modules such as cameras and infrared sensors. The road information in front includes the distance between the front vehicle and the speed of the front vehicle, and the road information, etc., and the corresponding digital information is projected in an imaging manner and closely combined with the environmental information of the front vehicle, wherein the digital information includes but is not limited to: vehicle speed, navigation information (road instructions), vehicle gear, cruise control, distance between the front vehicle and the front vehicle, speed information, power information, cruising range information, audio and video entertainment system information, etc., so that the driver can understand the information needed to drive the vehicle without shifting his sight when driving the vehicle. Avoid driving risks caused by the driver not being able to take into account the road conditions when driving the vehicle, such as looking down at the dashboard or the central control screen information.

[0084] To achieve the above projection, the car needs to have a head up display (HUD), wherein the head up display system may include a projection device 100 and an optical element, wherein the projection device 100 includes an optical system that can project an image, for example, the optical system includes an image generating unit, an image reflecting unit, an image magnifying unit, etc. The optical element may include a windshield 200 of the vehicle, or a reflective film attached to the windshield 200, or a screen separately arranged in the cabin of the car. The optical element may reflect and / or refract the image projected by the projection device 100 and then project it into the driver's eyes, so that the driver can obtain a virtual information image in front of the windshield 200. The projection device 100 has one or more interfaces, through which current and / or image signals are obtained from the central control system or the vehicle system of the vehicle, wherein the current signal is used to power the electrical devices in the projection device, and the image signal is used to provide the projected image.

[0085] The adapter device, HUD shell, HUD device, HUD system and mobile terminal provided by the present application will be described below in conjunction with the accompanying drawings.

Figure 4 A disassembly diagram of a HUD device provided in an embodiment of the present application is shown. Figure 2 and Figure 3 Schematic diagram of the structural disassembly of the HUD device.

[0087] Depend on Figures 2 to 4 It can be seen that the HUD device includes a HUD housing 10 and a switching device 20 .

[0088] The adapter 20 is installed on the HUD housing 10 .

[0089] The HUD housing 10 includes a first interface 101, and the first interface 101 is used to obtain current and / or image signals for the HUD device. The adapter 20 includes a second interface 201 and a third interface 301, and the second interface 201 is used to connect to the first interface 101, and the third interface 301 is used to connect to a first device, and the first device is used to provide current and / or image signals for the HUD device, for example, the first device is a central control system or a vehicle controller of a vehicle.

[0090] Among them, at least one of the current and the image signal is transmitted between the second interface 201 and the first interface 101. It can be understood that:

[0091] Only current is transmitted between the second interface 201 and the first interface 101 . Accordingly, the first interface 101 is a first power interface 101 a , and the second interface 201 is a second power interface 201 a .

[0092] Alternatively, only image signals are transmitted between the second interface 201 and the first interface 101 , and accordingly, the first interface 101 is the first signal interface 101 b , and the second interface 201 is the second signal interface 201 b .

[0093] Alternatively, the second interface 201 and the first interface 101 support simultaneous transmission of current and image signals.

[0094] Alternatively, the first interface 101 includes a first power interface 101a and a first signal interface 101b, the second interface 201 includes a second power interface 201a and a second signal interface 201b, current is transmitted between the first power interface 101a and the second power interface 201a, and image signals are transmitted between the first signal interface 101b and the second signal interface 201b.

[0095] Among them, at least one of the current and the image signal is transmitted between the third interface 301 and the second interface 201. It can be understood that:

[0096] Only current is transmitted between the third interface 301 and the second interface 201 . Accordingly, the second interface 201 is a second power interface 201 a , and the third interface 301 is a third power interface 301 a .

[0097] Alternatively, only image signals are transmitted between the third interface 301 and the second interface 201 , and accordingly, the second interface 201 is the second signal interface 201 b , and the third interface 301 is the third signal interface 301 b .

[0098] Alternatively, the third interface 301 and the second interface 201 support simultaneous transmission of current and image signals.

[0099] Alternatively, the second interface 201 includes a second power interface 201a and a second signal interface 201b, the third interface 301 includes a third power interface 301a and a third signal interface 301b, current is transmitted between the second power interface 201a and the third power interface 301a, and image signals are transmitted between the second signal interface 201b and the third signal interface 301b.

[0100] Current HUD devices usually use highly customized shells, and different mobile terminal (such as vehicles) models have different requirements for the type and location of the HUD external interface, resulting in different shapes of HUD shells. In addition, the HUD shell needs to be repeatedly designed and molded to meet the different requirements for the type and location of the HUD external interface, and the adaptability is poor.

[0101] For example, for a highly customized HUD shell 10 including a first interface 101, if a device or system in a certain vehicle model that needs to interface with the HUD system supports the third interface 301, because the first interface 101 cannot be adapted to the third interface 301, the HUD shell 10 cannot meet the needs of a certain vehicle model for the third interface 301. At this time, the HUD shell 10 needs to be repeatedly designed and molded so that the HUD shell 10 has the function of supporting the third interface 301 type, resulting in repeated design and mold opening of the HUD shell 10 and poor adaptability.

[0102] In the embodiment of the present application, by installing the adapter device 20 on the HUD shell 10, current and / or image signals are transmitted between the second interface 201 of the adapter device 20 and the first interface 101 of the HUD shell 10, and current and / or image signals are transmitted between the second interface 201 of the adapter device 20 and the third interface 301 of the adapter device 20. There is no need to repeatedly design and open a mold for the HUD shell 10, and the demand for the third interface 301 can be met. That is, the HUD shell 10 can be shared by different mobile terminal models (such as vehicles), and there is no need to repeatedly design and open a mold for the HUD shell 10 to meet different requirements for the type and position of the HUD external interface, thereby improving adaptability.

[0103] In a possible embodiment, the HUD device further includes a first cable 30 .

[0104] The first interface 101 of the HUD housing 10 and the second interface 201 of the adapter 20 are connected via the first cable 30 .

[0105] For details, please refer to Fig.10 , Fig.10 A schematic diagram of a cable provided in an embodiment of the present application.

[0106] It can be understood that when only current is transmitted between the second interface 201 and the first interface 101, the first interface 101 is the first power interface 101a, and the second interface 201 is the second power interface 201a. Accordingly, the first interface 101 and the second interface 201 are connected via a cable 30a.

[0107] Alternatively, when only image signals are transmitted between the second interface 201 and the first interface 101, the first interface 101 is the first signal interface 101b, and the second interface 201 is the second signal interface 201b. Accordingly, the first interface 101 and the second interface 201 are connected via a cable 30b.

[0108] Alternatively, when the second interface 201 and the first interface 101 support simultaneous transmission of current and image signals, correspondingly, the first interface 101 and the second interface 201 are connected via the cable 30 .

[0109] Alternatively, when the first interface 101 includes a first power interface 101a and a first signal interface 101b, and the second interface 201 includes a second power interface 201a and a second signal interface 201b, current is transmitted between the first power interface 101a and the second power interface 201a, and image signals are transmitted between the first signal interface 101b and the second signal interface 201b. Accordingly, the first power interface 101a and the second power interface 201a are connected via a cable 30a, and the first signal interface 101b and the second signal interface 201b are connected via a cable 30b.

[0110] It is understandable that no matter whether the first interface 101 and the second interface 201 are of the same type, the first interface 101 and the second interface 201 can be connected by a special first cable 30 to achieve transmission of current and / or image signals between the first interface 101 and the second interface 201.

[0111] The following will be combined Figure 5 to Figure 6 For the above Figures 2 to 4 The adapter 20 in the HUD device is explained.

[0112] Understandably, Figure 5 to Figure 6 The switching device shown can be regarded as the above Figures 2 to 4 A reasonable deformation or supplement of the switching device 20 in the HUD device; or, it can be understood that, Figure 5 to Figure 6 The switching device shown can also be regarded as an embodiment that can exist independently, and the present application does not impose any limitation on this.

[0114] Combined with the above Figures 2 to 4 ,Depend on Figure 5 to Figure 6 It can be seen that the switching device 20 includes a second interface 201 and a third interface 301 .

[0115] Among them, at least one of current and image signal is transmitted between the second interface 201 and the first interface 101. It can be understood that only current is transmitted between the second interface 201 and the first interface 101, and accordingly, the first interface 101 is the first power interface 101a, and the second interface 201 is the second power interface 201a. Alternatively, only image signals are transmitted between the second interface 201 and the first interface 101, and accordingly, the first interface 101 is the first signal interface 101b, and the second interface 201 is the second signal interface 201b. Alternatively, the second interface 201 and the first interface 101 support simultaneous transmission of current and image signals. Alternatively, the first interface 101 includes the first power interface 101a and the first signal interface 101b, and the second interface 201 includes the second power interface 201a and the second signal interface 201b, and current is transmitted between the first power interface 101a and the second power interface 201a, and image signals are transmitted between the first signal interface 101b and the second signal interface 201b.

[0116] Among them, at least one of current and image signal is transmitted between the third interface 301 and the second interface 201. It can be understood that only current is transmitted between the third interface 301 and the second interface 201, and accordingly, the second interface 201 is the second power interface 201a, and the third interface 301 is the third power interface 301a. Alternatively, only image signals are transmitted between the third interface 301 and the second interface 201, and accordingly, the second interface 201 is the second signal interface 201b, and the third interface 301 is the third signal interface 301b. Alternatively, the third interface 301 and the second interface 201 support simultaneous transmission of current and image signals. Alternatively, the second interface 201 includes the second power interface 201a and the second signal interface 201b, and the third interface 301 includes the third power interface 301a and the third signal interface 301b, and current is transmitted between the second power interface 201a and the third power interface 301a, and image signals are transmitted between the second signal interface 201b and the third signal interface 301b.

[0117] Current HUD devices usually use highly customized shells, and different mobile terminal (such as vehicles) models have different requirements for the type and location of the HUD external interface, resulting in different shapes of HUD shells. In addition, the HUD shell needs to be repeatedly designed and molded to meet the different requirements for the type and location of the HUD external interface, and the adaptability is poor.

[0118] For example, for a highly customized HUD shell 10 including a first interface 101, if a device or system in a certain vehicle model that needs to interface with the HUD system supports the third interface 301, because the first interface 101 cannot be adapted to the third interface 301, the HUD shell 10 cannot meet the needs of a certain vehicle model for the third interface 301. At this time, the HUD shell 10 needs to be repeatedly designed and molded so that the HUD shell 10 has the function of supporting the third interface 301 type, resulting in the problem of repeated design and mold opening of the HUD shell and poor adaptability.

[0119] In the embodiment of the present application, by installing the adapter device 20 on the HUD shell 10, current and / or image signals are transmitted between the second interface 201 of the adapter device 20 and the first interface 101 of the HUD shell 10, and current and / or image signals are transmitted between the second interface 201 of the adapter device 20 and the third interface 301 of the adapter device 20. There is no need to repeatedly design and open a mold for the HUD shell 10, and the demand for the third interface 301 can be met. That is, the HUD shell 10 can be shared by different mobile terminal models (such as vehicles), and there is no need to repeatedly design and open a mold for the HUD shell 10 to meet different requirements for the type and position of the HUD external interface, thereby improving adaptability.

[0120] In a possible embodiment, the type of the first interface 101 is the same as the type of the second interface 201 , and the type of the third interface 301 is different from the type of the second interface 201 .

[0121] It can be understood that according to the association relationship between the interface types corresponding to the above-mentioned first interface 101, the second interface 201, and the third interface 301, the first interface 101 can be communicated with the second interface 201, and the second interface 201 can be communicated with the third interface 301, so as to realize the first interface 101 of the HUD shell 10 being transferred to the third interface 301 of the adapter 20, thereby eliminating the need to repeatedly design and open the mold for the HUD shell 10 and meeting the demand for the third interface 301.

[0122] Optionally, the type of the first interface 101 and the type of the second interface 201 may also be different, as long as the type of the third interface 301 is different from the type of the first interface 101. In this case, the first interface 101 and the second interface 201 can be connected by a special cable to achieve the connection of the first interface 101 of the HUD housing 10 to the third interface 301 of the adapter 20.

[0123] Optionally, the types of the first interface 101, the second interface 201, and the third interface 301 may include but are not limited to the following interface types: controller area network (CAN) low-speed connection interface, vehicle-mounted coaxial radio frequency connection (FAChKReis Automobil, FAKRA) interface, vehicle-mounted high-speed signal connection (high speed data, HSD) interface, Ethernet (ETH) interface, low-voltage differential signal (LVDS) interface, control interface for connecting to power supplies, gateways and other devices, etc., and the embodiments of the present application are not limited to this.

[0124] For example, a highly customized HUD shell 10 including a first interface 101 which is a CAN low-speed connection interface cannot meet the requirements of a certain vehicle model for a third interface 301 (on-board high-speed signal connection interface). In this case, it is necessary to repeatedly design and open a mold for the HUD shell 10 so that the HUD shell 10 has the function of supporting the third interface 301 (on-board high-speed signal connection interface).

[0125] In the embodiment of the present application, by installing the adapter 20 on the HUD shell 10, current and / or image signals are transmitted between the second interface 201 (CAN low-speed connection interface) of the adapter 20 and the first interface 101 (CAN low-speed connection interface) of the HUD shell 10, and current and / or image signals are transmitted between the second interface 201 (CAN low-speed connection interface) of the adapter 20 and the third interface 301 (vehicle-mounted high-speed signal connection interface) of the adapter 20. There is no need to repeatedly design and open a mold for the HUD shell 10, and the demand for the third interface 301 (vehicle-mounted high-speed signal connection interface) can be met. That is, the HUD shell 10 can be shared by different mobile terminal models (such as vehicles), and there is no need to repeatedly design and open a mold for the HUD shell 10 to meet different requirements for the type and position of the HUD external interface, thereby improving adaptability.

[0126] In a possible embodiment, the second interface 201 and the third interface 301 are located on different sides of the switching device 20 .

[0127] In the embodiment of the present application, the second interface 201 and the third interface 301 are located on different sides of the switching device, which can improve the space utilization of the switching device 20 .

[0128] Optionally, the second interface 201 and the third interface 301 may also be located on the same side of the adapter 20 , which is not limited in the embodiment of the present application.

[0129] In a possible embodiment, the adapter 20 further includes a fourth interface 401 , and at least one of a current and an image signal is transmitted between the fourth interface 401 and the second interface 201 .

[0130] It is understandable that, on the basis that the adapter 20 includes the second interface 201 and the third interface 301, the adapter 20 also includes a fourth interface 401, and at least one of the current and the image signal is transmitted between the fourth interface 401 and the second interface 201. In this scenario, the first interface 101 of the HUD shell 10 can be transferred to the fourth interface 401 of the adapter 20 through the second interface 201 and the fourth interface 401. Therefore, there is no need to repeatedly design and open the mold for the HUD shell 10, and the demand for the fourth interface 401 can be met.

[0131] Optionally, the fourth interface 401 and the first interface 101 / the second interface 201 may be of the same type or different types, which is not limited in the embodiment of the present application.

[0132] Optionally, the fourth interface 401 and the third interface 301 may be of the same type or different types, which is not limited in the embodiment of the present application.

[0133] In a possible embodiment, the fourth interface 401 and the third interface 301 are located on the same side of the adapter 20 .

[0134] It can be understood that the fourth interface 401 and the third interface 301 are located on the same side of the adapter 20 , which can facilitate the routing of cables on the adapter 20 side.

[0135] Optionally, the fourth interface 401 and the third interface 301 may also be located at different sides of the switching device 20 , which is not limited in the embodiment of the present application.

[0136] In a possible embodiment, the switching device 20 further includes a switching module 2002 .

[0137] The second interface 201 and the third interface 301 are connected to the adapter module 2002 , and at least one of the current and the image signal is transmitted between the second interface 201 and the third interface 301 through the adapter module 2002 .

[0138] It can be understood that, based on the fact that the adapter device 20 includes a second interface 201 and a third interface 301, the adapter device 20 also includes an adapter module 2002, and the second interface 201 and the third interface 301 are both connected to the adapter module 2002, and the second interface 201 and the third interface 301 achieve communication connection through the adapter module 2002, that is, the second interface 201 and the third interface 301 transmit at least one of the current and the image signal through the adapter module 2002.

[0139] Optionally, the adapter module 2002 may be made of a printed circuit board (PCB).

[0140] Optionally, in addition to the adapter module 2002 , the adapter device 20 further includes an upper shell 2001 and a lower shell 2003 . The upper shell 2001 , the adapter module 2002 , and the lower shell 2003 together constitute the adapter device 20 .

[0141] In a possible embodiment, the adapter 20 is detachably mounted on the HUD housing 10 .

[0142] It is understandable that the installation position of the adapter 20 can be adjusted accordingly according to the space resources on the HUD housing 10 and the position requirements of the adapter 20.

[0143] Optionally, the adapter device 20 is detachably mounted on any position of the HUD housing 10, the position includes a first fixing portion, the first fixing portion is provided with a first through hole, the adapter device 20 includes a second fixing portion, the second fixing portion is provided with a second through hole, and the adapter device 20 is installed on the HUD housing 10 by inserting a fastener into the first through hole and the second through hole. Accordingly, by adjusting the fastener to be inserted into the through hole of the fixing portion of different positions, the adapter device 20 can be detachably installed on different positions of the HUD housing 10.

[0144] Optionally, the above-mentioned fasteners include but are not limited to screw threads, pins, etc., and the embodiments of the present application are not limited to this.

[0145] Optionally, any position of the HUD housing 10 may include one or more fixing parts, and correspondingly, the adapter 20 may include the same number of fixing parts, which is not limited in the embodiment of the present application.

[0146] In a possible embodiment, the third interface 301 is used to obtain at least one of a current and an image signal from the first device.

[0147] Optionally, the first device may be a central control system or a vehicle controller of the vehicle, etc., which provides current and / or image signals to the HUD device.

[0148] The following will be combined Figures 7 to 9 For the above Figures 2 to 4 The HUD housing 10 in the HUD device is described.

[0149] Understandably, Figures 7 to 9 The HUD housing shown can be regarded as the above Figures 2 to 4 A reasonable deformation or supplement of the HUD housing 10 in the HUD device; or, it can be understood that, Figures 7 to 9 The HUD housing shown can also be regarded as an embodiment that can exist independently, and the present application does not limit this.

[0150] See also Figures 7 to 9 , Figure 7 A schematic diagram of the overall assembly of a HUD housing provided in an embodiment of the present application is shown. Figure 8 A schematic diagram of the disassembly of a HUD housing provided in an embodiment of the present application is shown.

Fig. 9 A schematic diagram of the structure of a circuit board in a HUD housing provided in an embodiment of the present application is shown. Figure 7 and Figure 8 Schematic diagram of the structure of the circuit board in the HUD housing.

[0151] Combined with the above Figures 2 to 4 ,Depend on Figures 7 to 9 It can be seen that the HUD housing 10 includes a latching position 1003 .

[0152] The clamping position 1003 can be used to fix the adapter 20 installed on the HUD housing 10. The adapter 20 can refer to the above Figure 5 to Figure 6 The switching device shown will not be described in detail here.

[0153] Optionally, the HUD housing 10 may further include an upper housing 1001 and a lower housing 1002 , that is, the HUD housing 10 may be composed of an upper housing 1001 and a lower housing 1002 .

[0154] Current HUD devices usually use highly customized shells, and different mobile terminal (such as vehicles) models have different requirements for the type and location of the HUD external interface, resulting in different shapes of HUD shells. In addition, the HUD shell needs to be repeatedly designed and molded to meet the different requirements for the type and location of the HUD external interface, and the adaptability is poor.

[0155] For example, for a highly customized HUD shell 10 including a first interface 101, if a device or system in a certain vehicle model that needs to interface with the HUD system supports the third interface 301, because the first interface 101 cannot be adapted to the third interface 301, the HUD shell 10 cannot meet the needs of a certain vehicle model for the third interface 301. At this time, the HUD shell 10 needs to be repeatedly designed and molded so that the HUD shell 10 has the function of supporting the third interface 301 type, resulting in repeated design and mold opening of the HUD shell 10 and poor adaptability.

[0156] In the embodiment of the present application, by installing the adapter device 20 on the HUD shell 10, current and / or image signals are transmitted between the second interface 201 of the adapter device 20 and the first interface 101 of the HUD shell 10, and current and / or image signals are transmitted between the second interface 201 of the adapter device 20 and the third interface 301 of the adapter device 20. There is no need to repeatedly design and open a mold for the HUD shell 10, and the demand for the third interface 301 can be met. That is, the HUD shell 10 can be shared by different mobile terminal models (such as vehicles), and there is no need to repeatedly design and open a mold for the HUD shell 10 to meet different requirements for the type and position of the HUD external interface, thereby improving adaptability.

[0157] In a possible embodiment, the HUD shell 10 further includes a fastener, the clamping position 1003 includes a first fixing portion 1003a, the first fixing portion 1003a is provided with a first through hole, the adapter 20 includes a second fixing portion 2003a, the second fixing portion 2003a is provided with a second through hole, and the fastener is installed in the first through hole and the second through hole.

[0158] It can be understood that by inserting the fasteners into the first through hole and the second through hole, the adapter 20 can be installed on the HUD housing 10 .

[0159] Correspondingly, by adjusting the fasteners to pass through the through holes of the fixing parts at different positions, the adapter 20 can be detachably installed at different positions of the HUD housing 10 .

[0160] Optionally, the above-mentioned fasteners include but are not limited to screw threads, pins, etc., and the embodiments of the present application are not limited to this.

[0161] Optionally, any position of the HUD housing 10 may include one or more fixing parts, and correspondingly, the adapter 20 may include the same number of fixing parts, which is not limited in the embodiment of the present application.

[0162] In a possible embodiment, the HUD housing 10 further includes a fifth interface 501 .

[0163] The fifth interface 501 is used to transmit at least one of current and image signal.

[0164] It can be understood that the fifth interface 501 is only used to transmit current, and accordingly, the fifth interface 501 is a fifth power interface 501a. Alternatively, the fifth interface 501 is only used to transmit image signals, and accordingly, the fifth interface 501 is a fifth signal interface 501b. Alternatively, the fifth interface 501 supports simultaneous transmission of current and image signals. Alternatively, the fifth interface 501 includes a fifth power interface 501a and a fifth signal interface 501b, the fifth power interface 501a is used to transmit current, and the fifth signal interface 501b is used to transmit image signals.

[0165] It is understandable that, on the basis that the HUD shell 10 includes the first interface 101, the HUD shell 10 also includes a fifth interface 501, and the fifth interface 501 is used to transmit at least one of the current and the image signal. In this scenario, when the first interface 101 of the HUD shell 10 is occupied due to the communication connection with the second interface 201 of the adapter 20, the HUD shell 10 also has the function of supporting the fifth interface 501 type.

[0166] Optional, Fig. 9 The circuit board 1004 shown is located in the HUD shell 10 and is used to connect the upper shell 1001 and the lower shell 1002. In addition, the first interface 101 and the fifth interface 501 of the HUD shell are both connected to the circuit board 1004, and the transmission of current and / or image signals is achieved through the circuit board 1004.

[0167] Optional, Fig. 9 The circuit board 1004 shown may be made from a printed circuit board (PCB).

[0168] In a possible embodiment, the type of the fifth interface 501 is different from the type of the third interface 301 of the switching device 20 .

[0169] It is understandable that the type of the fifth interface 501 is different from the type of the third interface 301 of the adapter device 20. In this scenario, the adapter device 20 can be installed on the HUD shell 10 to expand the functions of the interface types not supported by the original HUD shell 10, thereby achieving the need to repeatedly design and open the mold of the HUD shell 10 and meet the needs of the third interface 301.

[0170] In a possible embodiment, the type of the fifth interface 501 is the same as the type of the first interface 101 of the HUD housing 10 .

[0171] It can be understood that the type of the fifth interface 501 of the HUD shell 10 is the same as the type of the first interface 101 of the HUD shell 10. In this scenario, even if the first interface 101 of the HUD shell 10 is occupied due to the communication connection with the second interface 201 of the adapter 20, the HUD shell 10 still has the function of supporting the type of the first interface 101, that is, it is possible to retain the functions of the interface types supported by the original HUD shell 101 while expanding the functions of the interface types not supported by the original HUD shell 10.

[0172] Optionally, the type of the fifth interface 501 may be different from the type of the first interface 101 of the HUD housing 10 , which is not limited in this embodiment of the present application.
