[0031] The above and other aspects, features and advantages of the present disclosure will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0032] Specific embodiments of the present disclosure are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments claimed are merely examples of the present disclosure, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid obscuring the present disclosure with unnecessary or redundant details. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present disclosure in a variety of ways with substantially any suitable detailed structure.

[0033] This specification may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0034] like Figure 1 As shown, the head-up display device includes a housing 10 and a buffer stopper 20. The housing 10 is provided with a first light outlet 111 and a receiving cavity connected to the first light outlet 111. The buffer stopper 20 is arranged on the upper surface of the housing 10 and located at the periphery of the first light outlet 111, and is used to limit the position of the support body of the head-up display device. The head-up display device also includes an imaging component, which is accommodated in the receiving cavity.

[0035] The head-up display device provided by the embodiment of the present disclosure is provided with a buffer stopper 20 on the upper surface of the shell 10. The buffer stopper 20 is located at the periphery of the first light outlet 111. Thus, while achieving a limit stop between the buffer stopper 20 and the carrier of the head-up display device and preventing foreign objects from falling into the internal space of the carrier, a buffer is also provided between the head-up display device and the carrier, thereby effectively reducing hard collisions, thereby reducing the risk of the head-up display device being squeezed and deformed or producing abnormal noises, and greatly improving the user experience.

[0036] In this embodiment, the imaging component includes an amplifying element and an image source. The image source can emit image light carrying image information, and the image light emitted by the image source is incident on the amplifying element; the amplifying element emits the image light from the first light outlet 111 to the external imaging component, so that the external imaging component reflects the image light to the eye box area to form a virtual image. In order to ensure the imaging effect, the shell 10 can be made of a light-shielding material to prevent external light from entering the accommodating cavity. Specifically, when the head-up display device is installed on a vehicle, the external imaging component is the windshield of the vehicle.

[0037] In this embodiment, the head-up display device is installed in a vehicle, so the carrier of the head-up display device is the center console of the vehicle.

[0038] In this embodiment, the buffer stopper 20 is NVH foam, where NVH stands for noise, vibration and harshness. Specifically, the buffer stopper 20 is an annular foam strip that matches the first light outlet 111. NVH foam has certain elasticity and good noise reduction performance. The use of the above material can effectively reduce the hard collision between the head-up display device and the center console, improve the buffering effect, and effectively absorb noise, thereby reducing the risk of the head-up display device being squeezed and deformed or producing abnormal noise. Of course, the buffer stopper 20 can also be other materials with similar properties, which can be selected according to actual needs.

[0039] like Figure 1 to Figure 2 , Figure 4 As shown, the housing 10 includes a dust cover housing 11, a main body 12 and a bottom cover 13 arranged in an upper and lower manner. The dust cover housing 11, the main body 12 and the bottom cover 13 are detachably connected, for example, by snaps or bolts. Specifically, the first light outlet 111 is provided on the upper surface of the dust cover housing 11, and the dust cover housing 11, the main body 12 and the bottom cover 13 together form a receiving cavity, wherein the imaging component is received in the main body 12, and the main circuit board of the head-up display device is received in the bottom cover 13.

[0040] like Figure 2 As shown, limiting ribs 114 are provided on the periphery of the upper surface of the dust cover shell 11, and the limiting ribs 114 protrude from the upper surface of the dust cover shell 11 and extend along its circumference. The outer side of the buffer stopper 20 abuts against the limiting ribs 114, thereby being limited and stopped by the limiting ribs 114, so that the buffer stopper 20 will not separate from the dust cover shell 11 in the horizontal direction.

[0041] like Figures 2 to 3 As shown, a water guide groove 112 is provided on the upper surface of the housing 10, and the water guide groove 112 connects the first light outlet 111 with the external environment of the housing 10. Specifically, the water guide groove 112 is located on the upper surface of the dust cover housing 11. Figure 3 As shown, the head-up display device further includes a dustproof film 30. An installation step is provided on the inner side of the first light outlet 111. The dustproof film 30 is installed on the installation step, and its surface is flush with the upper surface of the dust cover housing 11, thereby sealing the first light outlet 111 to prevent foreign matter from entering the accommodating cavity and affecting the normal use of the imaging component. At the same time, the dustproof film 30 will not affect the emission of image light. Furthermore, a sealing ring is provided between the installation step and the dustproof film 30, thereby improving the sealing performance of the dustproof film 30.

[0042] It is understandable that the water guide groove 112 extends to the edge of the dustproof film 30, so that when water droplets gather on the dustproof film 30, the water can be guided out in time to avoid affecting the normal emission of image light.

[0043] In this embodiment, the extension direction of the water guide groove 112 is from the inside to the outside of the dust cover shell 11, the inner groove section of the water guide groove 112 extends to the edge of the dust cover film 30, and the outer groove wall extends to the outer wall of the dust cover shell 11. In a preferred embodiment, the water guide groove 112 is set to be tilted downward from the inside to the outside. In other words, the water guide groove 112 is set to be tilted downward, the inner groove section of the water guide groove 112 is connected to the upper surface of the dust cover shell 11, and the outer groove section extends downward to communicate with the outer wall of the dust cover shell 11. In this way, water droplets can flow to the outside more easily with the help of gravity, thereby improving the water guiding effect of the water guide groove 112.

[0044] In this embodiment, in order to more effectively guide all the water droplets gathered on the dustproof film 30, the water guide groove 112 is located at the lowest point of the upper surface of the dust cover shell 11. Further, the water guide groove 112 can also be provided in plurality, and the plurality of water guide grooves 112 are arranged at intervals along the circumference of the upper surface of the dust cover shell 11, that is, arranged at intervals along the circumference of the first light outlet 111, wherein at least one water guide groove 112 is located at the lowest point of the upper surface of the dust cover shell 11.

[0045] like Figure 3 As shown, the corresponding part of the buffer stopper 20 and the water guide groove 112 is a reduced diameter section 21 to avoid the inner groove section of the water guide groove 112. Specifically, the reduced diameter section 21 can be considered to be formed by cutting away a part of the inner side of the buffer stopper 20, thereby exposing the inner groove section of the water guide groove 112, ensuring the connection between the water guide groove 112 and the first light outlet 111.

[0046] Due to the difference in temperature and humidity in the use environment, water vapor may accumulate inside the head-up display device, especially in the heat and humidity cycle related experiments. When the temperature and humidity change, water vapor is likely to accumulate inside the accommodating cavity, and then condense onto the dustproof film 30 and the imaging component, affecting the imaging. In order to avoid the above situation, Figure 4 As shown, the housing 10 is provided with an air vent 14, which is located at the bottom of the housing 10. It can be understood that the air vent 14 connects the accommodating cavity and the external environment of the housing 10. By providing the air vent 14, the condensation of water vapor in the accommodating cavity on the dustproof film 30 and the imaging component can be effectively slowed down, avoiding affecting the light transmission of the dustproof film 30 and the normal use of the imaging component.

[0047] In this embodiment, the head-up display device further includes a dustproof member, which is disposed in the air vent 14. Specifically, the dustproof member may be a dustproof net, so as to prevent dust and other impurities from entering the accommodating cavity through the air vent 14 and causing damage to the imaging component.

[0048] In this embodiment, there are a plurality of air holes 14, and the plurality of air holes 14 are arranged at intervals. Specifically, at least the bottom of the main body 12 and the bottom cover 13 are provided with air holes 14, so as to improve the dissipation efficiency of water vapor in the accommodating cavity.

[0049] like Figure 4 As shown, an electrical installation hole 131 is provided at the bottom of the bottom cover 13, and the electrical plug-in of the main circuit board is correspondingly arranged at the electrical installation hole 131, so as to be electrically connected with the power line and communication line of the vehicle.

[0050] like Figure 1 to Figure 2 , Figure 4As shown, the main body 12 is provided with two connecting arms 121, and the two connecting arms 121 are respectively located on both sides of the main body 12. The connecting arms 121 are provided with mounting holes, so that the head-up display device can be installed and fixed in the center console of the vehicle by connecting parts such as screws or bolts.

[0051] The disclosed embodiment also provides a vehicle, including the above-mentioned head-up display device. Specifically, the head-up display device is installed in the center console of the vehicle, the center console is provided with a second light outlet, the first light outlet 111 of the head-up display device is arranged corresponding to the second light outlet, the center console has an inwardly protruding mounting flange, the mounting flange is arranged along the periphery of the second light outlet, and the buffer stopper 20 is sleeved on the bottom of the mounting flange, so that the bottom of the mounting flange is accommodated in the buffer stopper 20, thereby preventing foreign matter from falling into the internal space of the center console from the second light outlet. Correspondingly, the external imaging component of the head-up display device is the windshield of the vehicle.
