[0002] The content described in this section is provided only as background information about this disclosure and does not constitute prior art.

[0003] A head-up display (HUD) is a device that displays an image containing information such as vehicle speed, remaining fuel, and navigation guidance on the windshield of a vehicle. HUDs are typically configured to reflect head-up information projected from a graphics unit (PGU) onto the windshield using an aspherical mirror.

[0004] In addition, when the driver's line of sight changes, the head-up display is configured to adjust the height of the information displayed on the windshield by rotating the aspherical mirror to adjust the reflection angle of the aspherical mirror.

[0005] Head-up displays (HUDs) are located inside the vehicle's cockpit. In the event of a frontal collision between a vehicle equipped with a HUD and an object, the HUD may be damaged, potentially causing additional injury to passengers. Furthermore, in the event of a collision between a vehicle and a pedestrian, the pedestrian's head or body may impact the area surrounding the HUD, posing a threat to the pedestrian's life.

[0040] Figure 2 It is according to the embodiments of this disclosure along Figure 1 A cross-sectional view taken from line A-A'.

[0041] Reference Figure 1 and Figure 2 The head-up display device 100 may include all or some of the housing 110, the aspherical lens 120, and the collapsible area.

[0042] The housing 110 may include a lower housing 111 and an upper housing 112.

[0043] The lower housing 111 can be configured to have an opening at its top. The lower housing 111 can define an internal space to accommodate various components of the head-up display device 100.

[0044] The lower housing 111 can be configured to house various components of the head-up display device 100. For example, the lower housing 111 can accommodate multiple components for displaying images on the windshield, such as an image generation unit or a drive module.

[0045] The image generation unit can generate images containing information such as vehicle speed, remaining fuel, and navigation guidance. The image generation unit may include an LED PCB (LED printed circuit board), a display, a funnel, a diffuser (not shown), etc.

[0046] The drive module can rotate the aspherical mirror 120 by raising or lowering the linkage unit based on the rotational force of the motor. This is an exemplary configuration, but it is not necessarily limited to it.

[0047] The upper housing 112 can be configured to correspond to the lower housing 111. The upper housing 112 can be configured to cover the top of the lower housing 111.

[0048] The upper housing 112 can be attached to the upper contour of the lower housing 111 to form a closed area. That is, after the various components of the head-up display device are installed in the lower housing 111, the upper housing 112 can be screwed onto at least one fastener of the lower housing 111 to complete the assembly of the head-up display device.

[0049] The aspherical mirror 120 can be configured to reflect an image emitted from the image generation unit onto the windshield. The aspherical mirror 120 can be housed in the lower housing 111.

The aspherical mirror 120 can be positioned in front of the image generation unit along the forward optical path and can be configured to alter the path of the image output from the image generation unit. The forward optical path refers to the path from the image output from the image generation unit to the driver of the vehicle.

[0051] The crumple zone may include impact absorption unit 130. Here, the crumple zone refers to a specific area that absorbs the impact through structural damage in the event of a vehicle collision and prevents the impact from being transmitted to indestructible areas, thereby minimizing damage.

[0052] By creating a crumple zone, the head-up display device 100 can be intentionally designed to deform or break, thereby minimizing damage to critical internal components of the head-up display device 100 and injury to passengers and pedestrians.

[0053] The impact absorption unit 130 can be configured to be housed in the housing 110 and absorb the impact transmitted to the housing 110 in the event of a vehicle collision.

[0057] refer to Figure 3 The crumple zone may also include multiple notches 140. The notches 140 may be configured to cause damage to the housing 110 and disperse the impact transmitted to the housing 110.

[0058] Here, notch 140 refers to a groove or cut that is designed to easily cause structural deformation or damage, and is a part created so that it will break at the intended location when an impact is applied.

[0059] A notch 140 may be formed on a surface of the housing 110 corresponding to the forward direction of the vehicle. Specifically, a plurality of notches 140 may be formed on a surface of the upper housing 112 corresponding to the forward direction of the vehicle.

[0060] The plurality of recesses 140 formed on the upper housing 112 may extend along the surface of the lower housing 111 corresponding to the forward direction of the vehicle. However, this is an exemplary configuration and is not necessarily limited thereto.

[0061] Multiple notches 140 may be formed on at least one other surface adjacent to one surface of the housing 110. Specifically, multiple notches 140 may be formed on the upper surface and side surfaces of the upper housing 112. Furthermore, multiple notches 140 may be formed on the lower surface and side surfaces of the lower housing 111. However, this is an exemplary configuration and is not necessarily limited thereto.

[0062] The notch 140 can be configured such that the recess is formed toward the interior of the housing 110. Specifically, the notch 140 can be formed as a V-shaped recess toward the interior of the housing 110, such that damage occurs at the intended location when an impact is applied. However, this is an exemplary configuration and is not necessarily limited thereto.
