The augmented reality Head-Up Display (Augmented Reality-Head Up Display, AR-HUD) is an automobile auxiliary vision safe driving system, which projects some important information required by a driver during driving onto automobile front windshield glass through an AR-HUD light path, and achieves fusion of Display information and surrounding live-action, so that the driver can directly obtain real-time road condition information and vehicle related information on the front windshield glass.

The existing AR-HUD can only be arranged at the position between the automobile instrument panel and the front windshield, otherwise, the ideal imaging effect cannot be achieved, however, the AR-HUD is arranged between the automobile instrument panel and the front windshield, and an air conditioner defrosting opening originally positioned above the instrument panel is blocked. In this way, when there is a temperature difference between the inside and the outside of the vehicle, the frost formed on the inside of the front windshield is extremely easy to fog, and the frost formed on the inside of the front windshield is difficult to completely remove by the defrosting port, so that the driving safety of a driver is affected. At present, the front windshield is defrosted and defogged mainly by means of electric heating glass, but the defrosting and defogging cost of the mode is increased.

Based on this, the applicant provides a new line display device for new line display device also can possess certain defrosting function through setting up vent line and first vent in new line display device, thereby has solved originally that the automobile defrosting defogging mouth is blocked and thus can't carry out under the circumstances of effective defrosting defogging, improves the effect to front windshield defrosting, reduces the possibility that influences the safety of driver's driving vehicle.

The embodiment of the application provides a head-up display device 000, and the head-up display device 000 can be an AR-HUD. Referring to fig. 1, fig. 1 is a schematic perspective view of a head-up display device 000 for installation in a cabin of a vehicle according to an embodiment of the present application, and the head-up display device 000 may include a device body 100, a defrosting member 200, and a ventilation line 300.

The device body 100 in the head-up display device 000 has a light outlet S on a side facing the front windshield of the vehicle. For example, a display module for emitting light may be disposed in the device body 100, and a light beam emitted by the display module may pass through the device body 100 through the light outlet S, and finally, a virtual image is presented on the front windshield, so that a driver can observe in real time during driving.

The defrosting member 200 in the head-up display device 000 may be connected to the device body 100 at the light outlet K of the device body 100. The defrost element 200 has a first vent K1 on a side facing away from the apparatus body 100.

Here, the light outlet S of the apparatus body 100 and the first vent K1 of the defrosting member 200 may be disposed in parallel, that is, the light outlet S of the apparatus body 100 and the first vent K1 of the defrosting member 200 are both disposed toward the same direction. For this reason, after the head-up display device 000 is mounted in the cockpit of the vehicle, both the light outlet S of the device body 100 and the first vent K1 of the defroster 200 may be directed toward the front windshield of the vehicle.

It should be noted that, by arranging the light outlet S of the device body 100 and the first vent K1 of the defrosting member 200 in parallel, when the head-up display device 000 is actually used, only one of the light outlet S of the device body 100 and the first vent K1 of the defrosting member 200 needs to be ensured to be directed toward the front windshield, and separate adjustment is not needed, so that the complexity of installing the head-up display device 000 can be reduced, and meanwhile, the processes of manufacturing the light outlet S of the device body 100 and the first vent K1 of the defrosting member 200 are summarized, and because the orientations of the two are the same, the two processes can be manufactured together, thereby simplifying the process steps and reducing the complexity of production.

The vent line 300 in the head-up display device 000 may communicate with the first vent K1 of the defrost 200. Wherein the vent line 300 in the head-up display device 000 may be configured to blow air toward the front windshield through the first vent K1 of the defrost 200.

In the embodiment of the present application, after the front windshield is frosted and the fogging phenomenon occurs, the ventilation pipeline 300 can blow air toward the front windshield through the first ventilation opening K1 of the defrosting member 200, so that the frosting on the inner side of the front windshield can be effectively removed. In this way, even if the defroster opening in the vehicle is blocked by the head-up display device 000, it is ensured that frost formed on the inner side of the front windshield of the vehicle can be normally removed by the defrosting member 200 in the head-up display device 000, and thus the safety of the driver driving the vehicle can be effectively improved.

In summary, the head-up display device provided by the embodiment of the application comprises a device body, a defrosting piece and a ventilation pipeline. Since the first vent in the defrost can be directed towards the front windshield of the vehicle, the first vent can be in communication with the vent line. Thus, the vent line can blow air toward the front windshield through the first vent in the defrost. Therefore, after the front windshield is frosted and the fog phenomenon occurs, the first ventilation opening in the defrosting piece can blow towards the front windshield through the cooperation of the ventilation pipeline and the defrosting piece, so that the frosting on the inner side of the front windshield can be effectively removed. Therefore, even if the defrosting opening in the vehicle is shielded by the head-up display device, frosting on the inner side of the front windshield of the vehicle can be guaranteed to be normally removed by the defrosting piece in the head-up display device, and the safety of a driver in driving the vehicle can be effectively improved.

In the embodiment of the present application, as shown in fig. 1, the orthographic projection of the defrosting member 200 on the plane of the light outlet S of the device body 100 is not overlapped with the light outlet S. In this case, even if the defrosting member 200 is provided at the light outlet S of the apparatus body 100, it is ensured that the defrosting member 200 does not block the light beam emitted from the light outlet S of the apparatus body 100, and thus it is ensured that the apparatus body 100 can normally project a virtual image to the front windshield of the vehicle through the light outlet S.

Alternatively, as shown in fig. 1, the defrosting member 200 in the head-up display device 000 has a ring shape, and the light outlet S of the device body 100 may be located in an area surrounded by the defrosting member 200. For this reason, the light beam emitted from the light outlet S of the apparatus body 100 may pass through the area surrounded by the defrosting member 200 and then be projected onto the front windshield of the vehicle.

For example, the area of the orthographic projection of the area surrounded by the defrosting member 200 on the plane where the light outlet S of the apparatus body 100 is located may be slightly larger than the area of the light outlet S of the apparatus body 100. In this way, it is ensured that the defroster 200 does not block the light beam emitted from the light outlet S of the apparatus body 100 in the process of projecting the light beam emitted from the light outlet S of the apparatus body 100 onto the front windshield of the vehicle.

Alternatively, referring to fig. 2,3 and 4, fig. 2 is a schematic structural diagram of another head-up display device according to an embodiment of the present application, fig. 3 is a top view of the head-up display device shown in fig. 2, and fig. 4 is a cross-sectional view of a defrosting member at A-A' in the head-up display device shown in fig. 2. The defrosting member 200 has a plurality of first vents K1, and an annular air duct K3 communicating with the plurality of first vents K1. The plurality of first vents K1 in the defrosting member 200 may be arranged around the annular air duct K3, and the annular air duct K3 in the defrosting member 200 may communicate with the ventilation duct 300.

Here, since the defrosting member 200 may have a ring shape, the ring-shaped air duct K3 may be directly provided inside the defrosting member 200, that is, the defrosting member 200 body having a ring shape belongs to a hollow structure. Moreover, each first ventilation opening K1 in the defrosting member 200 may be communicated with the annular air duct K3, and after the annular air duct K3 in the defrosting member 200 is directly communicated with the ventilation pipeline 300, the ventilation pipeline 300 may blow air to the annular air duct K3 in the defrosting member 200, so that the annular air duct K3 may blow air to the front windshield of the vehicle through each first ventilation opening K1. Because the plurality of first ventilation openings K1 in the defrosting member 200 are arranged around the annular air duct K3, the plurality of first ventilation openings K1 in the defrosting member 200 can uniformly blow air to the front windshield of the vehicle, thereby improving the defrosting effect on the front windshield.

Optionally, a heating element capable of heating air may be additionally arranged in the annular air duct K3 in the defrosting element 200, so as to ensure that the air blown to the front windshield of the vehicle is stable hot air, and further ensure that the heat carried in the hot air can melt frost on the inner side of the front windshield, thereby further improving the defrosting effect on the front windshield. The heating element may include a thermal resistor, a heating fin, and other heating elements capable of heating air.

Optionally, a pressurizing member capable of pressurizing air may be additionally provided in the annular air duct K3 of the defrosting member 200, so that the force of blowing out each first ventilation opening K1 toward the front windshield is ensured to be large, and the defrosting effect on the front windshield can be further improved. The pressurizing member may include a compressor, a small air compressor, and other pressurizing members capable of pressurizing air.

It should be noted that, since the annular air duct K3 in the defrosting member 200 can store and pressurize the air blown from the ventilation pipeline 300, the heat loss and the temperature reduction possibility of the air blown from the ventilation pipeline 300 can be reduced by the air storage capacity of the annular air duct K3, so that the defrosting and demisting effects can be better ensured. Moreover, through the pressurization effect of the annular air duct K3, the flow speed of the air blown out by the first ventilation opening K1 is faster, and the air can reach the front windshield more accurately.

In addition, can also set up the deep bead in first vent K1 department to with deep bead and first vent K1 swing joint, and set up a driving piece in inside, move through driving piece drive baffle, in order to accomplish and shelter or expose first vent K1, thereby guarantee when not needing to use defrosting defogging function, first vent K1 department can not get into the dust, thereby influence display module's display effect.

For example, the baffle plate and the first ventilation opening K1 may be selectively connected in a rotating manner, and a linear driving member is disposed at the first ventilation opening K1, and the output end of the linear driving member is fixedly connected to an end of the baffle plate far away from the first ventilation opening K1 and connected in a rotating manner, and the baffle plate is driven to move by the linear driving member, so as to complete shielding or exposing of the first ventilation opening K1.

Optionally, as shown in FIG. 2, the heads-up display device 000 may further include a branch line 400 and a control valve (not shown) located within the branch line 400. Here, both ends of the branch line 400 may be respectively communicated with the annular air channel K3 and the ventilation line 300 in the defrosting unit 200. The control valve located within the branch line 400 has an open state and a closed state.

When the control valve is in the open state, the ventilation pipeline 300 can blow air to the annular air duct K3 in the defrosting member 200 through the branch pipeline 400, and further blow air to the front windshield of the vehicle through each first ventilation opening K1 communicated with the annular air duct K3, and when the control valve is in the closed state, the ventilation pipeline 300 stops blowing air to the annular air duct K3 in the defrosting member 200, and further can stop blowing air to the front windshield of the vehicle.

Illustratively, in the embodiment of the present application, the control valve may be located at any position in the branch line 400, or may be located at the connection between the branch line 400 and the ventilation line 300, or at the connection between the branch line 400 and the annular air channel K3 in the defrosting member 200. Here, the control valve may include a shut-off valve, an electromagnetic valve, and other valves capable of controlling the connection and disconnection of the annular duct K3 and the ventilation line 300 in the defrosting unit 200, and specifically what valve is selected as the control valve may be set according to actual use requirements, which the present application is not limited.

In the embodiment of the application, a controller can be arranged in the cab, the controller is electrically connected with the control valve, and the opening and closing of the control valve can be controlled by the controller. It will be appreciated that the controller may also be integrated on the cabin air conditioning panel or on the head up display device 000 control panel in order to conform to the operating habits of the driver.

Alternatively, referring to fig. 3, the defrosting member 200 has a second vent K2 at a side facing the apparatus body 100, the second vent K2 is in communication with the ventilation line 300, and the ventilation line 300 is further configured to blow air to the light outlet S of the apparatus body 100 through the second vent K2. Like this, ventilation line 300 not only can blow towards the front windshield of vehicle through first vent K1, can also blow towards the light opening S of equipment body 100 through second vent K2 to blow away the dust that gathers in the light outlet S department of equipment body 100, make the effect of the light beam that the light outlet S of equipment body 100 was emergent better, and then can guarantee that its virtual image' S that throws on the front windshield display effect that forms is better. For this reason, the defrosting member 200 has not only the effect of removing frost on the inner side of the front windshield, but also the effect of removing dust collected at the light outlet S of the apparatus body 100.

For example, the second air openings K2 in the defrosting member 200 may be in communication with the annular air channel K3, and the number of the second air openings K2 in the defrosting member 200 is plural, and the plural second air openings K2 may be arranged around the annular air channel K3. Thus, the ventilation duct 300 communicating with the annular air duct K3 in the defrosting member 200 can blow toward the front windshield of the vehicle through the respective first ventilation openings K1 communicating with the annular air duct K3 after blowing toward the annular air duct K3, and in the process, can blow toward the light outlet S of the apparatus body 100 through the respective second ventilation openings K2 communicating with the annular air duct K3.

In the embodiment of the present application, the ventilation pipeline 300 in the head-up display device 000 may have various air supply modes, and the present application is described by taking two implementation modes as examples:

In a first alternative implementation, the ventilation line 300 in the head-up display device 000 may be placed in direct communication with the vehicle's ventilation system to supply air to the head-up display device 000 via the vehicle's ventilation system. Here, the ventilation system of the vehicle may include at least one of an air conditioning system of the vehicle, an inside-outside air circulation system of the vehicle, and a defrost system of the vehicle. To this end, the ventilation line 300 in the head-up display device 000 may include at least one of an air-conditioning supply pipe communicating with an air-conditioning system of the vehicle, an air circulation pipe communicating with an inside and outside air circulation system of the vehicle, and a defrost pipe communicating with a defrost system of the vehicle.

It should be noted that, the ventilation system of the vehicle supplies air to the ventilation pipeline 300, so that the existing vehicle can simply reconfigure the pipeline in the original ventilation system of the vehicle to put the head-up display device 000 into use, and the universality of the head-up display device 000 is increased.

It should be further noted that in this case, by providing a control valve in the branch line 400 in the head-up display device 000, the communication and disconnection between the ventilation line 300 and the annular air channel K3 in the defrosting member 200 can be controlled. Thus, under the condition that the front windshield of the vehicle is not required to be defrosted, the control valve can control the ventilation pipeline 300 to stop blowing the air to the annular air channel K3 in the defrosting piece 200, so that the ventilation system of the vehicle can not blow the air to the annular air channel K3 in the defrosting piece 200 through the ventilation pipeline 300, and the ventilation system of the vehicle can be guaranteed to be ventilated in the vehicle better, and the energy consumption of the vehicle can be reduced.

In addition, can integrate control valve and the interior air conditioner control panel of vehicle, control the control valve through air conditioner control panel, can also increase the control valve pilot lamp in air conditioner control panel department for the driver can directly observe on air conditioner panel and adjust the control valve, in order to accord with driver's driving habit, reduce because the control valve forgets the meaningless energy consumption of vehicle that closes and lead to.

In a second alternative implementation, an air supply assembly 500 may be additionally provided to supply air to the ventilation pipeline 300. By way of example, as shown in FIG. 4, the head-up display device 000 may further include an air supply assembly 500, an air outlet face of the air supply assembly 500 may be directed toward one end of the vent line 300, and an end of the vent line 300 facing away from the air supply assembly 500 may be in communication with the first vent K1 in the defrost element 200. Here, an end of the ventilation line 300 facing away from the air supply assembly 500 may communicate with the first ventilation opening K1 through the branch line 400 and the annular air channel K3 in the defrosting member 200. Alternatively, the air supply assembly 500 may include fans, small compressors, and other air supplies that can supply air to the ventilation circuit 300 to complete the air supply to the ventilation circuit 300.

It should be noted that, by directing the air outlet surface of the air supply assembly 500 toward one end of the ventilation pipeline 300, the wind energy provided by the air outlet surface of the air supply assembly 500 can directly enter the ventilation pipeline 300, and the one end of the ventilation pipeline 300, which is away from the air supply assembly 500, is communicated with the first ventilation opening K1 in the defrosting member 200, so as to ensure that the ventilation pipeline 300 can blow more efficiently to the first ventilation opening K1 in the defrosting member 200.

Optionally, referring to fig. 5, fig. 5 is a sectional view of the head-up display device at B-B' shown in fig. 2, and the head-up display device 000 further includes a dustproof film 700 fixedly connected to the device body 100 at the light outlet S, and a light shielding plate 600 movably connected to the device body 100 at the light outlet S. Wherein the light shielding plate 600 is closer to the defrosting member 200 than the dustproof film 700.

For example, a layer of light-permeable dustproof film 700 may be covered on the light outlet S of the device body 100, so as to prevent dust from entering the display module disposed in the light outlet S, thereby affecting the display effect of the display module. Here, a light shielding plate 600 may be further disposed between the defrosting member 200 and the dustproof film 700, and the light shielding plate 600 may be selectively slidably connected to the light outlet S of the defrosting member 200 or may be selectively rotatably connected to the light outlet S of the defrosting member 200.

In this way, the light shielding plate 600 does not shield the light outlet S when the head-up display device 000 is required to be used, and external dust is difficult to enter the device body from the light outlet S when the head-up display device 000 is not required to be used, so that the possibility that the display effect of the head-up display device 000 is affected due to ash falling of the display module is reduced.

In addition, the applicant surprisingly found that dust on the surface of the dustproof film 700 also affects the light transmission of the head-up display device 000, so as to affect the display effect of the head-up display device 000, most of the top of the dustproof film 700 on the current head-up display device 000 is not shielded, and the whole head-up display device 000 presents a concave state on the instrument desk, so that dust is easy to accumulate on the dustproof film 700, and because the dustproof film 700 is special in material and is not easy to clean, it can be understood that dust is accumulated at the light outlet S due to the fact that dust is hard to be cleaned, so that the transmission of virtual image light is seriously affected, and display brightness and display definition are affected. The applicant sets up the second ventilation hole through the side at defrosting piece 200 towards equipment body 100, blows away the dust on dust membrane 700 or dustproof glass surface through the second ventilation hole, reduces the possibility that the dust is piled up, promotes the projection ability of virtual image light, promotes the display brightness and the definition of new line display device 000 simultaneously.

The application also provides a vehicle, referring to fig. 6, fig. 6 is a schematic diagram of installation cooperation of a head-up display device and a front windshield, which is provided by the embodiment of the application, and the vehicle comprises a cockpit and the head-up display device installed in the cockpit, wherein the head-up display device is the head-up display device. The vehicles include commercial vehicles, electric vehicles, and other vehicles having a cockpit.

Referring again to fig. 1 to 6, when the present embodiment is operated, the following steps are performed:

when the front windshield 001 is required to be defrosted and defogged, the controller is opened, the control valve is opened by the controller to communicate the ventilation pipeline 300 with the annular air duct K3, the air conditioner in the vehicle is simultaneously opened, at the moment, the air blown by defrosting and defogging of the air conditioner passes through the ventilation pipeline 300, the branch pipeline 400 and the annular air duct K3 from the air conditioner air pipe, and then the defrosting and defogging air is blown onto the front windshield 001 from the first air outlet arranged on the defrosting piece 200, so that the defrosting and defogging effect of the front windshield 001 is achieved, after defrosting and defogging are finished, the controller is closed, the control valve is closed by the controller to disconnect the ventilation pipeline 300 and the annular air duct K3, and thus the defrosting and defogging operation is finished.

When the dustproof film 700 needs to be defrosted and defogged, the controller is opened, the controller is utilized to open the control valve so as to communicate the ventilation pipeline 300 with the annular air duct K3, and meanwhile, the air conditioner in the vehicle is opened, at the moment, the air blown by defrosting and defogging of the air conditioner passes through the ventilation pipeline 300, the branch pipeline 400 and the annular air duct K3 from the air conditioner air pipe, and then the defrosting and defogging air is blown to the surface of the dustproof film 700 from the first air outlet arranged on the defrosting piece 200, so that dust on the surface of the dustproof film 700 is blown away, and the display process of the dustproof film 700 can be cleaned. When the head-up display device 000 is displayed to be closed, the controller controls the light shielding cover to be closed, so that the cleaning of the upper surface of the dust-proof film 700 can be ensured even when not displayed. Thereby ensuring the cleaning of the surface of the dust-proof film 700 both when in use and when not in use. Thereby ensuring that the display effect of the head-up display is not affected by dust on the surface of the dustproof film 700.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application. Accordingly, the scope of protection of the present application is to be determined by the appended claims.
