Description

Head-Up Display Apparatus The present disclosure relates to a head-up display device. The content described in this section merely provides background information regarding the present disclosure and does not constitute prior art. The Head-Up Display projects an image generated by a Picture Generation Unit onto an aspheric mirror, illuminating it toward the vehicle's windshield. Here, the aspheric mirror includes a spherical mount for mounting inside the Head-Up Display. An aspherical mirror is fixed by applying pressure to a spherical mount using a screen and an elastic body. To prevent over-restraint of the aspherical mirror, clearance is formed in a direction perpendicular to the rotation axis of the aspherical mirror. However, if an external force is continuously applied in a direction perpendicular to the rotation axis of the aspherical mirror, the elastic displacement of the elastic body is exceeded, and there is a problem in which damage or wear occurs to the aspherical mirror. FIG. 1 is an exploded perspective view showing the configuration of a head-up display device according to one embodiment of the present disclosure. FIG. 2 is a combined perspective view of a head-up display device according to one embodiment of the present disclosure. FIG. 3 is a plan view showing the configuration of a head-up display device according to one embodiment of the present disclosure. Figure 4 is a cross-sectional view taken along A-A of Figure 3. 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. In describing the components of the present invention, terms such as first, second, A, B, (a), (b), etc. may be used. These terms are used merely to distinguish the components from other components, and the essence, order, or sequence of the components is not limited by the terms. Where it is stated that one component is 'connected', 'combined', or 'joined' to another component, it should be understood that while the component may be directly connected or joined to the other component, another component may also be 'connected', 'combined', or 'joined' between each component. Terms such as 'part', 'module', etc., as described in the specification refer to a unit that processes at least one function or operation, and this may be implemented in hardware, software, or a combination of hardware and software. Unless otherwise stated, it should be noted that the description of any one embodiment may also apply to other embodiments. The description of the invention disclosed below, together with the accompanying drawings, is intended to describe exemplary embodiments of the invention and is not intended to represent the only embodiment in which the invention may be practiced.
