Description

Technical Field

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

[0002] Head-up displays, also known as heads-up displays (HUDs), are commonly used in aircraft flight control systems and are now becoming increasingly common in automobiles. HUDs are designed to improve vehicle safety, allowing drivers to focus on the road and reduce accidents. The HUD market has grown rapidly in recent years, with an increasing number of car models now equipped with HUDs.

[0003] For HUD products, drivers of different heights have different requirements for the position of the HUD image. The projection position needs to be adjusted to ensure that the driver can see the image projected by the HUD at the best viewing angle. Traditional HUD products are fixed in front of the dashboard for projection display. Such products cannot adapt to the needs of drivers of different heights when in use. That is, due to different viewing angles when different drivers observe the HUD, the HUD image will become lower or higher, which is inconvenient for the driver to observe vehicle information and road information, and may easily induce safety accidents. Some HUD products also use the internal main lens to flip back and forth to achieve the height change of the image to meet the needs of drivers of different heights. However, when facing complex road conditions, the main lens's rotating shaft is prone to breakage, resulting in blurred imaging or glare that may induce safety accidents. Utility Model Content

[0004] The main purpose of the utility model is to provide a head-up display and a vehicle with adjustable projection imaging height.

[0005] To achieve the above object, the present invention provides a head-up display, comprising:

[0006] The HUD body includes a chassis and a light-transmitting cover located on top of the chassis;

[0007] a linear actuator, disposed outside the chassis, for driving the HUD body to move in a first direction;

[0008] The first outlet baffle is provided on one side of the light-transmitting cover and has the ability to deform along a first direction;

[0009] The second outlet baffle is arranged at the other side of the light-transmitting cover away from the first outlet baffle and has a deformation capability along a first direction.

[0010] Furthermore, the structures of the outlet baffle 1 and the outlet baffle 2 are the same, both including retractable flat plates connected to each other and an inclined plate connected to the light-transmitting cover, and the light emitted by the HUD body passes between the inclined plates of the outlet baffle 1 and the outlet baffle 2.

[0011] Furthermore, the flat plate is a corrugated expansion plate.

[0012] Furthermore, the flat plate is composed of a plurality of hollow plates that are movably connected in sequence.

[0013] Furthermore, the HUD body also includes an optical engine, reflector 1 and reflector 2 installed in the chassis, reflector 1 is arranged on the light-emitting side of the optical engine, and reflector 2 is arranged on the light-emitting side of reflector 1. The light with an image emitted by the optical engine is reflected by reflector 1 and reflector 2, and then emitted through the light-transmitting cover.

[0014] Furthermore, the light-transmitting cover is plated with a dielectric film, and the chassis is sprayed with matte paint.

[0015] Furthermore, the light-transmitting cover is in the shape of an inwardly concave arc surface.

[0016] The utility model also provides a vehicle, comprising a main instrument panel, a windshield, and the above-mentioned head-up display;

[0017] The head-up display is installed in the inner cavity of the main instrument panel through the linear drive; a light outlet for light emitted by the HUD body is provided on the main instrument panel, the outlet baffle 1 is connected between the front edge of the light outlet and the HUD body, and the outlet baffle 2 is connected between the rear edge of the light outlet and the HUD body.

[0021] The beneficial effects of the present invention are as follows:

[0022] When the present invention is in use, the HUD body projects an image obliquely upward onto the windshield, and then projects it to a certain distance outside the windshield through the windshield. The HUD body can be adjusted forward and backward through a linear drive, so that the image projected onto the windshield can be adjusted in height, which is convenient for drivers of different heights to observe effectively, so that the driver does not need to lower or raise his head to view, thereby ensuring safe driving. In addition, this drive installation method is more solid and avoids the risk of the lens rotation shaft breaking in some extreme cases. In addition, when the HUD body moves, the first and second outlet baffles can be deformed along with the movement of the HUD body, thereby keeping the opening size of the light outlet basically unchanged, avoiding the problem of the main instrument panel table being hollow due to the opening being too large, and making up for the shortcomings in design and actual production.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0033] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0034] See also Figure 1 .

[0035] The utility model head-up display comprises:

[0036] The HUD body 1 includes a chassis 14 and a light-transmitting cover 15 located on the top of the chassis 14;

[0037] a linear actuator 2, disposed outside the chassis 14, for driving the HUD body 1 to move in a first direction;

[0038] An outlet baffle 1 3 is provided on one side of the light-transmitting cover 15 and has the ability to deform along a first direction;

[0039] The second outlet baffle 4 is disposed on the other side of the light-transmitting cover 15 away from the first outlet baffle 3 and has a deformation capability along a first direction.

[0040] The head-up display of the present invention can be used in various types of vehicles, such as the vehicle illustrated in the figure, which includes a main instrument panel 01 and a windshield 05; the head-up display is installed in the inner cavity of the main instrument panel 01 through the linear drive 2; the main instrument panel 01 is provided with a light outlet 02 for light emitted through the HUD body 1, the outlet baffle 1 3 is connected between the front edge of the light outlet 02 and the HUD body 1, and the outlet baffle 2 4 is connected between the rear edge of the light outlet 02 and the HUD body 1.

[0041] When the present invention is in use, the HUD body 1 projects an image obliquely upward onto the windshield 05, and the image is projected to a certain distance outside the windshield 05 through the refraction effect of the windshield 05. The HUD body 1 can be adjusted forward and backward through the linear drive 2, so that the image projected onto the windshield 05 can be adjusted in height, which is convenient for drivers of different heights to observe effectively, so that the driver does not need to lower or raise his head to view, ensuring safe driving. In addition, this drive installation method is more solid and avoids the risk of the lens rotation shaft breaking in some extreme cases. In addition, when the HUD body 1 moves, the outlet baffle 1 3 and the outlet baffle 2 4 can be deformed along with the movement of the HUD body 1, thereby keeping the opening size of the light outlet 02 basically unchanged, avoiding the problem of the main instrument panel table being hollow due to the opening being too large, and making up for the shortcomings in design and actual production.

[0042] In one embodiment, the exit baffle 1 3 and exit baffle 2 4 have the same structure, each comprising interconnected, retractable flat plates 31 and 41 and inclined plates 32 and 42 connected to the light-transmitting cover 15. Light emitted from the HUD body 1 passes between the inclined plates 42 of exit baffle 1 3 and exit baffle 2 4. This design allows the flat plates 31 and 41 of exit baffle 1 3 and exit baffle 2 4 to expand and contract as the HUD body 1 moves forward and backward, maintaining the size of the light outlet 02 substantially constant and preventing an excessively large opening that could create a hollow space on the main instrument panel.

[0043] In one embodiment, the flat plate 31; 41 is a corrugated expansion plate. Alternatively, in one embodiment, as Figure 2 As shown, the flat plate 31; 41 is composed of a plurality of hollow plates 34 that are movably connected in sequence. The present invention is not particularly limited, and the flat plate only needs to be able to be extended.

[0044] In one embodiment, the HUD body 1 further includes an optical engine 11, a first reflector 12, and a second reflector 13, mounted within the chassis 14. The first reflector 12 is located on the light-emitting side of the optical engine 11, and the second reflector 13 is located on the light-emitting side of the first reflector 12. The image-bearing light emitted by the optical engine 11 is reflected by the first reflector 12 and the second reflector 13 before being emitted through the light-transmitting cover 15. This design provides a reasonable installation layout and is more suitable for projection onto the windshield 05.

[0045] In one embodiment, the light-transmitting cover 15 is coated with a dielectric film, and the chassis 14 is sprayed with matte paint. This design allows the dielectric film to reduce the entry of infrared light, which has high energy. If a large amount of infrared light enters, it can be reflected and focused on the LCD screen, potentially causing screen burn-in. The matte paint effectively protects the interior of the HUD body 1 from dust, preventing sunlight backflow and screen burn-in, as well as the effects of HUD projection stray light, thereby improving projection quality.

[0046] In one embodiment, the light-transmitting cover 15 is concavely curved. This design prevents stray light. When external light enters the HUD body from above or from the side, it is reflected once on the surface of the light-transmitting cover 15. The reflected light then strikes the first and second exit baffles. This prevents stray light from being reflected onto the windshield 05 and into the human eye, causing glare and other risks that could harm driving.

[0047] In one embodiment, the inclined plates 32; 42 are subjected to a matte treatment, such as spraying matte paint or performing a matte treatment.

[0048] In one embodiment, the vehicle further includes a front panel 03 and a CCB main beam 04; the linear drive 2 is installed on the front panel 03 and the CCB main beam 04, and the linear drive 2 drives the head-up display to move along a first direction on the vehicle.

[0049] In one embodiment, the linear actuator 2 includes a lead screw 21, a slide rod (located behind the lead screw and not shown in the figure for the sake of simplicity), and a slider 22. The ends of the lead screw 21 are rotatably mounted on the front panel 03 and the CCB main beam 04, respectively. The ends of the slide rod are fixedly mounted on the front panel 03 and the CCB main beam 04, respectively. The slider 22 penetrates the lead screw 21 and the slide rod and engages with the lead screw 21 and the slide rod in a sliding manner. The HUD body 1 is fixed to the slider 22. This design is simple and easy to implement. It is a commonly used lead screw and nut mechanism. The reciprocating rotation of the lead screw 21 is driven by a motor, which is converted into reciprocating sliding of the slider 22, driving the HUD body 1 to adjust its front and rear position. This transmission method has higher precision than traditional transmission methods such as slide rails, meeting the precision requirements of HUD optical projection systems.

[0050] In one embodiment, a PVB film is applied to the inner surface of the windshield 05. This design can reduce the ghosting effect of the projected image and improve the clarity of the projection.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
