  7. In Article 6, The above front shock absorber is, A head-up display device further comprising a projection configured to be fitted into a groove formed on one side of the front portion of the lower case.
  8. In Article 6, The above rear compression section is, A head-up display device in which a region of the center of the rear compression part is positioned in contact with the aspherical mirror so that the aspherical mirror can support the impact transmitted to the front shock absorber.
  9. In Article 5, The above head shock absorber is, An impact transmission portion extending along the longitudinal direction of the front portion of the upper case to disperse the impact transmitted to the upper case; At least one upper compression member formed such that the center protrudes toward the shock transmission member; A second core part formed in correspondence with the shock transmission part to disperse the shock transmitted from the upper compression part; At least one lower compression part formed to be symmetrical to the upper compression part with respect to the second core part and having a center protruding toward the bottom surface of the housing; and A second connecting part configured to fix the upper compression part, the second core part, and the lower compression part to both sides of the upper case. A head-up display device including
  10. In Article 9, The above lower compression part is, A head-up display device in which a region of the center of the lower compression part is positioned in contact with the front shock absorber so that the front shock absorber can support the shock transmitted to the head shock absorber.

Description

Head-up Display Apparatus The present disclosure relates to a head-up display device. More specifically, it relates to a head-up display device in which a crumple zone is formed to absorb impact in the event of a collision of a vehicle. The content described in this section merely provides background information regarding the present disclosure and does not constitute prior art. A head-up display is a device that displays images containing vehicle speed, fuel level, and navigation information on the windshield. Generally, a head-up display is configured to display head-up display information projected from a picture graphic unit (PGU) on the windshield by reflecting it through an aspherical mirror. In addition, when the driver's eye level changes, the aspherical mirror is rotated to adjust its reflection angle, thereby configuring the height of the information displayed on the windshield to be adjusted. The head-up display is located inside the cockpit of a vehicle. If a vehicle equipped with a head-up display collides head-on with an object, the head-up display may be damaged, potentially causing additional injury to the occupants. Additionally, if the vehicle collides with a pedestrian, there is a risk that the pedestrian's head or body may collide with the area near the head-up display, posing a threat to the pedestrian's life. FIG. 1 is a perspective view showing a head-up display device according to one embodiment of the present disclosure. FIG. 2 is a cross-sectional view taken along A-A' of FIG. 1 according to one embodiment of the present disclosure. FIG. 3 is a perspective view showing a head-up display device including a plurality of notches added to one embodiment of FIG. 1. FIG. 4 is an exploded perspective view showing the configuration of a head-up display device according to one embodiment of the present disclosure. FIG. 5 is a plan view showing the configuration of a front shock absorber according to one embodiment of the present disclosure. FIG. 6 is a plan view showing a configuration in which a front shock absorber according to one embodiment of the present disclosure is arranged in contact with an aspherical mirror. FIG. 7 is a plan view showing the configuration of a shock absorber including an added projection according to one embodiment of the present disclosure. FIG. 8 is a plan view showing the configuration of a head shock absorber according to one embodiment of the present disclosure. FIG. 9 is a plan view showing a configuration in which a head shock absorber according to one embodiment of the present disclosure is arranged in contact with a front shock absorber. Some embodiments of the present disclosure are described in detail below with reference to the exemplary drawings. It should be noted that in assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the present disclosure, if it is determined that a detailed description of related known components or functions could obscure the essence of the present disclosure, such detailed description is omitted. In describing the components of the embodiments according to the present disclosure, symbols such as first, second, i), ii), a), b), etc., may be used. These symbols are intended only to distinguish the components from other components, and the essence, order, or sequence of the components is not limited by the symbols. When a part in the specification is described as 'comprising' or 'having' a component, this means that, unless explicitly stated otherwise, it does not exclude other components but may include additional components. FIG. 1 is a perspective view showing a head-up display device according to one embodiment of the present disclosure. FIG. 2 is a cross-sectional view taken along A-A' of FIG. 1 according to one embodiment of the present disclosure. Referring to FIGS. 1 and 2, a head-up display apparatus (100) may include all or part of a housing (110), an aspherical mirror (120), and a crumple zone. The housing (110) may include a lower case (111) and an upper case (112). The lower case (111) may be configured so that the top is open. The lower case (111) may form an internal space to accommodate various configurations of the head-up display device (100). The lower case (111) can be configured as a structure for internally combining various components of the head-up display device (100). For example, the lower case (111) can accommodate multiple components for displaying an image on the windshield, such as a picture generator unit and a driving module. The image forming device can form an image containing vehicle speed, remaining fuel level, route guidance information, etc. The image forming device may include an LED PCB (LED Printed Circuit Board), a display, a funnel, a diffuser (not shown), etc. The drive module can rotate the aspherical mirror (120) by raisi
