Description

Technical Field

[0001] The utility model relates to the technical field of commercial vehicles, in particular to a head-up display assembly and a commercial vehicle. Background Art

[0002] The vehicle head-up display system (HUD) is a car auxiliary visual safety driving system. It projects some important information needed by the driver when driving, such as speed, navigation, Bluetooth calls, etc., to the front of the car windshield through this system. Through the mirror image, the driver can see the virtual image suspended above the engine cover. In this way, the driver's eyes are always focused on the front field of vision, reducing the visual blind spot caused by lowering the head, thereby greatly improving driving safety.

[0003] In the relevant technologies, the installation rate of HUD in the passenger car field has increased year by year, and the trend of HUD replacing instrument panels has become increasingly obvious. However, in the commercial vehicle field, it is more difficult to install HUD in commercial vehicles. Due to the space requirements of commercial vehicles and the large inclination angle of the front windshield of commercial vehicles, if the traditional method used in passenger cars is used to arrange HUD, the downward viewing angle of HUD will be too low, and the driver needs to lower his head to see the HUD image, which seriously affects driving safety.

[0030] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0031] Reference below Figure 1-Figure 4 The head-up display assembly 100 according to the embodiment of the present invention is described. The head-up display assembly 100 can be applied to commercial vehicles.

[0032] Combination Figure 1 As shown, the head-up display assembly 100 according to the present invention may mainly include: an instrument panel 10 , a front windshield 20 and a head-up display 30 .

[0033] The instrument panel 10 is provided with a controller, the front windshield 20 is provided at the front side of the instrument panel 10, the head-up display 30 is provided at the instrument panel 10 of the commercial vehicle and is electrically connected to the controller, and the light emitted by the head-up display 30 is reflected to the driver's eyes through the front windshield 20. The horizontal plane is set as the reference plane 200, and the light emitted by the head-up display 30 and reflected to the driver's eyes through the front windshield 20 is set as the reflected light 400, and an angle α is formed between the reflected light 400 and the reference plane 200, and α satisfies the relationship: 0°<α<15°.

[0034] Specifically, when the head-up display assembly 100 is working, the image generated by the controller is transmitted to the head-up display 30 for display. The head-up display 30 reflects the image to the driver's eyes through the front windshield 20, so that the driver can see the driving information on the front windshield 20 and obtain important driving data without having to lower his head to look at the instrument panel 10 or the central control screen, thereby improving driving safety and convenience, reducing the time the driver's eyes are away from the road, and reducing the risk of distracted driving.

[0035] Among them, the light emitted by the head-up display 30 is reflected to the driver's eyes through the front windshield 20, the horizontal plane is set as the reference plane 200, the light emitted by the head-up display 30 is reflected to the driver's eyes through the front windshield 20 as the reflected light 400, and the angle formed between the reflected light 400 and the reference plane 200 is the lower viewing angle, which is crucial to the readability and driving safety of the head-up display assembly 100.

[0036] Considering that the space of commercial vehicles is different from that of passenger vehicles, the tilt angle between the front windshield 20 of commercial vehicles and the horizontal plane is about 75°, which is also greater than the tilt angle of the front windshield 20 of passenger vehicles. The head-up display assembly originally used for passenger vehicles cannot be adapted to commercial vehicles. By setting the lower viewing angle within a reasonable range, the head-up display assembly 100 can be adapted to the mounting requirements of commercial vehicles. When driving a commercial vehicle, the user can see the driving information without lowering his head, which can ensure the readability of the display screen projected on the front windshield 20 by the head-up display 30 and ensure driving safety.

[0037] It should be noted that the attached Figure 1The eyellipse 500 shown in the figure is a statistical representation of the "driver's eye position". The driver's eyellipse 500 refers to the statistical distribution of the eye position of drivers of different body sizes in the vehicle body coordinate system after they adjust the seat to a suitable position according to their own wishes and sit in a normal driving posture. The eyellipse 500 can be used as a reference for the transparent area of ​​the front windshield 20, the front field of view, and the display area of ​​the head-up display 30. That is, if the light emitted by the head-up display 30 is reflected by the front windshield 20 to the eyellipse 500, it can enter the driver's eyes.

[0038] Therefore, by setting the angle between the reflected light 400 and the reference plane 200 within a reasonable range, that is, setting the lower viewing angle of the head-up display assembly 100 within a reasonable range, the head-up display assembly 100 can be adapted to the mounting requirements of commercial vehicles, and the driver can see the image without lowering his head, thereby ensuring driving safety.

[0039] In one embodiment of the present application, Figure 1-Figure 3 As shown, the upper end of the head-up display 30 at least partially protrudes from the upper surface of the instrument panel 10 , and the light emitting side of the head-up display 30 is located at the upper end of the head-up display 30 .

[0040] Specifically, considering that the tilt angle of the front windshield 20 of the commercial vehicle is too large, if the head-up display 30 is directly arranged below the instrument panel 10, the downward viewing angle of the head-up display assembly 100 will be too low, and the driver needs to lower his head to observe the driving information. Also, considering that the instrument panel 10 of the commercial vehicle is small in size, there is insufficient space inside the instrument panel 10 for installing the head-up display 30.

[0041] By at least partially protruding the upper end of the head-up display 30 from the upper surface of the instrument panel 10, the light-emitting side of the head-up display 30 is located at the upper end of the head-up display 30, so that the lower viewing angle of the head-up display assembly 100 can be adjusted to be within a reasonable range, thereby ensuring the readability of the driving information displayed on the front windshield 20 and ensuring driving safety. It should be noted that the specific height of the upper end of the head-up display 30 protruding from the upper surface of the instrument panel 10 needs to be designed according to the specific layout of different commercial vehicles, and is not specifically limited here.

[0042] In another embodiment of the present application, the inclination angle between the front windshield 20 of the commercial vehicle and the horizontal plane can also be reduced, so that the downward viewing angle of the head-up display assembly 100 can be adjusted so that the downward viewing angle of the head-up display assembly 100 is within a reasonable range, thereby ensuring the readability of the driving information displayed on the front windshield 20 and ensuring driving safety.

[0043] In another embodiment of the present application, the inclination angle between the outgoing light of the head-up display 30 and the horizontal plane can also be reduced, so that the downward viewing angle of the head-up display assembly 100 can be adjusted so that the downward viewing angle of the head-up display assembly 100 is within a reasonable range, thereby ensuring the readability of the driving information displayed on the front windshield 20 and ensuring driving safety.

[0044] Combination Figure 1-Figure 3 As shown, the head-up display assembly 100 may further include a sunshade 40, which is disposed on the instrument panel 10 and covers the outside of the head-up display 30, and a light outlet 41 is opened on the upper side of the sunshade 40, and the light outlet 41 corresponds to the light outlet side of the head-up display 30, and the light outlet 41 is higher than the light outlet side of the head-up display 30.

[0045] Specifically, considering that the upper end of the head-up display 30 at least partially protrudes from the upper surface of the instrument panel 10, external stray light may enter the head-up display 30 and enter the driver's eyes under the reflection of the head-up display 30, or first fall on the front windshield 20 under the reflection of the head-up display 30, and then enter the driver's eyes under the reflection of the front windshield 20, thereby affecting the display image.

[0046] By setting the sunshade 40, setting the sunshade 40 on the outside of the head-up display 30, and making the light outlet 41 of the sunshade 40 correspond to the light outlet side of the head-up display 30, and making the light outlet 41 higher than the light outlet side of the head-up display 30, the sunshade 40 covers the head-up display 30 without affecting the normal light outlet of the head-up display 30, thereby preventing stray light from entering the light outlet side of the head-up display 30, and blocking light reflected at the light outlet side of the head-up display 30, thereby preventing external stray light from entering the driver's eyes under reflection, and ensuring the imaging quality of the display picture and the normal operation of the head-up display assembly 100.

[0047] Combination Figure 1 and Figure 2 As shown, the head-up display 30 may include an outgoing light source 32, and an outgoing light 300 emitted by the outgoing light source 32 is emitted from the light-emitting side of the head-up display 30 and irradiates the front windshield 20. The inner wall of the sunshade 40 in the front-to-back direction is inclined relative to the horizontal plane and the inclination angle is β. The outgoing angle of the outgoing light 300 is γ, and β and γ satisfy the relationship: β=γ. Among them, the outgoing angle of the outgoing light 300 refers to the angle between the outgoing light 300 and the horizontal plane.

[0048] Specifically, by setting the inclination angle of the inner wall of the light shading hood 40 in the front-to-back direction to be equal to the exit angle of the exiting light 300, it is possible to avoid the light shading hood 40 blocking the exiting light 300, avoid affecting the normal light emission of the head-up display 30, and avoid affecting the display brightness and imaging quality of the head-up display 30.

[0049] Furthermore, the inner walls of the shading hood 40 in the front-to-rear direction are inclined, so: the inner wall of the shading hood 40 located at the rear extends forward toward the light-emitting side of the head-up display assembly 100, so that the inner wall of the shading hood 40 located at the rear can at least partially block the light-emitting side of the head-up display 30.

[0050] On the one hand, the inner wall of the sunshade 40 at the rear shields the external stray light, preventing the stray light from being reflected on the light exit side to the front windshield 20 first, and then reflected on the driver's eyes at the front windshield 20. On the other hand, when the stray light is reflected on the light exit side to directly enter the eyes of the driver, the inner wall of the sunshade 40 at the rear can also block the reflection path of the stray light, preventing the stray light from directly entering the eyes of the driver after being reflected on the light exit side.

[0051] In this way, the structural design of the sunshade 40 can be further optimized, so that the sunshade 40 can block stray light without affecting the normal light output of the head-up display 30, thereby ensuring the display brightness and imaging quality of the head-up display 30.

[0052] Combination Figure 2-Figure 4 As shown, a dustproof film 31 is provided on the light-emitting side of the head-up display 30, and the dustproof film 31 is a light-transmitting dustproof film. In this way, the light inside the head-up display 30 can be projected onto the front windshield 20 through the dustproof film 31, and the dustproof film 31 can also prevent dust, fingerprints, oil stains and other pollutants from directly contacting and adhering to the internal structure of the head-up display 30, which can not only prevent dust from causing failure of the internal structure of the head-up display 30, but also prevent dust from affecting the display effect, display brightness and imaging quality. Therefore, the dustproof film 31 can be provided to maintain the cleanliness of the head-up display 30, ensure image clarity, improve the working performance of the head-up display 30, and extend the working life of the head-up display 30.

[0053] Combination Figure 3 As shown, the dust-proof film 31 is located inside the light shielding cover 40 and is spaced apart from the inner wall of the light shielding cover 40 . The distance between the dust-proof film 31 and the inner wall of the light shielding cover 40 is D, and D satisfies the relationship: 0<D<3mm.

[0054] Specifically, the shading hood 40 is arranged on the outer periphery of the head-up display 30. By locating the dustproof film 31 inside the shading hood 40 and spacing the inner wall of the shading hood 40 from the dustproof film 31, the distance between the dustproof film 31 and the inner wall of the shading hood 40 is controlled within a reasonable range. In this way, the assembly error can be controlled to avoid assembly abnormalities due to production precision. It can not only ensure the normal installation and setting of the shading hood 40 on the outside of the head-up display 30, but also avoid the distance between the dustproof hood and the inner wall of the shading hood 40 being too large, which causes the accumulation of external dust and stains inside.

[0055] Combination Figure 4 As shown, the head-up display 30 may include an outgoing light source 32 , which emits light toward the light-emitting side of the head-up display 30 , and the brightness of the light emitted by the outgoing light source 32 is Q, and Q satisfies the relationship: 0<Q≤185w nit.

[0056] Specifically, when the head-up display 30 is working, the outgoing light source 32 emits light, which is sequentially projected onto the surface of the front windshield 20 through the primary curved mirror 36 and the secondary curved mirror 37, and then reflected by the front windshield 20 to the driver's eyes.

[0057] In order to ensure that the display brightness projected on the glass can be suitable for any scene during driving, a high-power outgoing light source 32 can be used. Under the premise that the brightness of the light emitted by the outgoing light source 32 is adjustable, the brightness emitted by the outgoing light source 32 can reach a maximum of 185w nit, thereby improving the display brightness of the head-up display assembly 100 and enhancing the user experience. The outgoing light source 32 can be a high-power LED lamp, which is not specifically limited here.

[0058] Optionally, considering the actual use requirements and heat dissipation requirements, the brightness of the light emitted by the outgoing light source 32 can be set to 133w nit, which will not be elaborated here.

[0059] Combination Figure 4 As shown, the head-up display 30 may further include a polarizer 33, which is disposed on the light-emitting side of the outgoing light source 32. Specifically, the polarizer 33 allows light waves with a specific polarization direction to pass through, while blocking or greatly attenuating light waves with a polarization direction perpendicular (or nearly perpendicular) to the outgoing light source 32. By arranging the polarizer 33 on the light-emitting side of the outgoing light source 32, the polarizer 33 can filter the light waves emitted by the outgoing light source 32, thereby reducing the energy of the emitted light waves, avoiding heat accumulation inside the head-up display 30, and further ensuring the normal operation of the head-up display 30 and extending the service life of the head-up display 30.

[0060] Combination Figure 4As shown, the head-up display 30 may further include a heat dissipation fan 34, and the heat dissipation fan 34 corresponds to the outgoing light source 32. Specifically, in order to meet the brightness of the light emitted by the outgoing light source 32, the outgoing light source 32 will generate more heat when working. By adding a heat dissipation fan 34 in the head-up display 30 and making the heat dissipation fan 34 correspond to the outgoing light source 32, when the outgoing light source 32 works and generates heat, the heat dissipation fan 34 can play a role in heat dissipation, thereby preventing the outgoing light source 32 from overheating, and preventing heat accumulation inside the head-up display 30, thereby ensuring the normal operation of the head-up display 30 and extending the service life of the head-up display 30.

[0061] In addition, the head-up display 30 is also provided with a radiator 35, which is arranged at the rear side of the outgoing light source 32 and corresponds to the outgoing light source 32 to play a role in heat dissipation. In some embodiments of the utility model, the volume of the radiator 35 in the head-up display 30 can also be increased to improve the heat dissipation capacity of the radiator 35, thereby further avoiding heat accumulation inside the head-up display 30 and ensuring the normal operation of the head-up display 30. It should be noted that the specific volume of the radiator 35 needs to be designed according to the specific layout of the instrument panel 10 of different commercial vehicles, and is not specifically limited here.

[0062] Furthermore, since the front windshield 20 of the commercial vehicle is too large, it is difficult to manufacture it by press molding, and it can only be manufactured by gravity molding. However, the glass surface of the gravity molding process is difficult to meet the corresponding requirements of the head-up display 30, and it is easy to cause dynamic distortion.

[0063] Therefore, when designing and producing the head-up display 30, the primary curved mirror 36 and the secondary curved mirror 37 of the head-up display 30 can be preliminarily optically designed based on the computer-aided modeling data of the windshield 20. Then, after the front windshield 20 is manufactured, the surface shape of the actually manufactured windshield 20 is scanned, and the primary curved mirror 36 and the secondary curved mirror 37 of the head-up display 30 are optically redesigned based on the surface shape of the actually manufactured windshield 20, so that the head-up display 30 matches the actually manufactured windshield 20, thereby improving dynamic distortion.

[0064] The commercial vehicle according to the utility model may mainly include: a head-up display assembly 100. Specifically, the head-up display assembly 100 may be adapted to the mounting requirements of the commercial vehicle, and by applying the head-up display assembly 100 to the commercial vehicle, driving safety may be further guaranteed, driving experience may be enhanced, and product competitiveness of the commercial vehicle may be improved.
