[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] The head-up display (HUD) projects important driving information such as speed and navigation onto the windshield in front of the driver, so that the driver can see important driving information such as speed and navigation without lowering or turning his head. Existing HUDs can be divided into C-HUD, W-HUD, and AR-HUD according to different projection methods and positions. The C-HUD display is a piece of transparent resin glass placed above the instrument, with a simple structure and relatively low cost. W-HUD uses the principle of optical reflection to project important driving-related information onto the windshield for display, which has a more integrated display effect and also helps the owner to drive safely. AR-HUD integrates AR technology into the HUD optical projection system, overlays digital images on the real world we see, and integrates the information projected by the HUD with the real driving environment. Both W-HUD and AR-HUD need to be displayed in conjunction with the car's windshield. When the head-up display function needs to be displayed, it needs to be placed in the car for display or a special booth is made to facilitate simple and quick operation of the HUD and display of images.

[0035] Reference Figures 1 to 4 The support frame 10 further includes a first bracket 104 for connecting to the base plate 102 and to both sides of the windshield assembly 20 respectively.

[0036] Specifically, two first brackets 104 are provided, and the two first brackets 104 are respectively located on both sides of the bottom plate 102 and are respectively connected with both sides of the head-up display 100. The first bracket 104 is a quasi-L-shaped structure, that is, the first bracket 104 is divided into a horizontal plate and a vertical plate. The lengths of the horizontal plates of the two first brackets 104 can be different to adapt to the position of the protruding structures on both sides of the head-up display 100 and the installation angle of the windshield assembly 20. The two first brackets 104 are arranged at intervals to form a placement space for the head-up display 100, and the protruding structure is set on the first bracket 104 and fixedly connected with screws, so that the head-up display 100 is stably installed in the first space. The top of the first bracket 104 is also connected to the windshield assembly 20 to support the windshield assembly 20, so that the head-up display 100 can project the picture onto the windshield assembly 20 for display, simulating the real vehicle display environment.

[0038] Specifically, the second bracket 201 includes a triangular support plate 2011 and a support plate 2012, the support plate 2012 and the first bracket 104 are fixedly connected by bolts, the top of the support plate 2011 is bent toward the direction close to the windshield 202 to form a top plate 2013, and the surface of the top plate 2013 is the placement surface of the windshield 202. The height of one end of the top plate 2013 is higher than the height of the other end, that is, the top plate 2013 has an angle with the horizontal plane, so as to simulate the installation environment of the car windshield.

[0039] The ends of the two second brackets 201 are bent to form a placement groove, and the windshield 202 is placed in the placement groove. The second bracket 201 is provided with a limit block 2014, and the limit block 2014 is located on both sides of the windshield 202 to limit the windshield 202.

[0040] Specifically, the lower end of the top plate 2013 is bent upward to form a placement groove to limit the windshield 202 in the vertical direction. At the same time, the limit block 2014 set along the length of the placement surface of the top plate 2013 limits the windshield 202 in the horizontal direction, so that the windshield can be stably placed on the second bracket 201.

[0041] Furthermore, a pad 203 is provided between the second bracket 201 and the windshield 202. Specifically, the pad 203 is laid along the placement surface of the top plate 2013 and the part in contact with the windshield 203. The pad 203 can be made of felt, sponge pad, rubber pad, etc., to reduce the hard contact between the windshield 202 and the top plate 201, reduce the wear on the windshield, and reduce the friction noise of the glass during movement.

[0042] Reference Figure 1-Figure 4 As shown, the display device also includes a shading component 40, which includes a first shading member 401 and a second shading member 402 that are relatively arranged, the two ends of the first shading member 401 are respectively connected to the two second brackets 201, the two ends of the top of the second shading member 402 are respectively connected to the two second brackets 201, and the bottom of the second shading member 402 is located on one side of the head-up display 100 and forms a gap with the head-up display 100.

[0043] Specifically, since the head-up display 100 projects images, it has high requirements for the environment. In the above-mentioned display device, the head-up display 100 is exposed to the external environment. At this time, the external ambient light will interfere with the display of the head-up display 100 and affect the display quality of the projected image. Therefore, the present solution sets a shading component 40 to block the external ambient light to reduce the impact of the external ambient light on the display of the head-up display 100.

[0044] In this embodiment, the shading assembly 40 includes a first shading member 401 and a second shading member 402 that are arranged opposite to each other, and are used to respectively block the ambient light in front of and behind the head-up display 100. The ambient light on the side is blocked by the first bracket 104 and the second bracket 201, so that the head-up display 100 is in an environment that is relatively suitable for display. Among them, the first shading member 401 can be used to block the ambient light behind the head-up display 100, and the second shading member 402 can be used to block the ambient light in front of the head-up display 100. The first shading member 401 is a concave-shaped plate, and both ends of the first shading member 401 are respectively connected to the side of the second bracket 201 close to the head-up display 100. The second shading member 402 includes a shading plate 4021 and a fixing plate 4022. Both ends of the top of the fixing plate 4022 are detachably connected to the ends of the top plate 2013 to form a placement groove, and the bottom of the fixing plate 4022 is fixedly connected to the shading plate 4021. The shading plate 4021 is arranged in front of the head-up display 100, and there is a gap between the two, that is, the shading plate 4021 does not contact the head-up display 100. At the same time, the connection between the shading plate 4021 and the fixing plate 4022 forms an angle greater than 0°. Through this series of structural designs, the fixing plate 4022 is better connected to the top plate 2013, and the shading plate 4021 can also more appropriately block ambient light.

[0045] Among them, the shading plate 4021 and the fixed plate 4022 can adopt one or more forms of snap connection, bonding, welding, etc. For example, a slot is opened on the shading plate 4021, and a card plate is set on the fixed plate 4022, and the card plate and the slot are snapped together, and then glue is used to make it more stable. Of course, the shading plate 4021 and the fixed plate 4022 can also be made as one piece.

[0046] In this embodiment, since the head-up display 100 is exposed outside, the user can see the structural structure of the head-up display more intuitively and clearly, that is, the user can perceive the function of the head-up display 100 and understand the product structure intuitively.

[0047] Reference Figures 2 to 4 The control component 30 includes a touch screen 301, a support member 302 and a control host (not shown); the touch screen 301 is mounted on the support member 302, the support member 302 is fixed to the base plate 102, and the control host is stored in the second space of the support frame 10.

[0048] Specifically, the touch screen 301 can facilitate the user to operate and control the head-up display 100. One end of the support member 302 is connected to the bottom plate 102, and the other end is connected to the touch screen 301. The connection end of the support member 302 is distributed to match the shape structure of the bottom plate 102 and the touch screen 301. The control host includes a PCBA control board, which is placed in the drawer assembly 103 to perform overall control of the head-up display 100 and the touch screen 301. When the head-up display 100 shows a fault, the drawer assembly 103 can be quickly pulled out to quickly inspect and adjust the control host.

[0049] In a possible implementation, four first brackets 104 are provided (not shown), and the four plate-shaped first brackets 104 form a cover body surrounding the head-up display 100, wherein at least two of the first brackets 104 have inner walls provided with raised connecting parts, so that the head-up display 100 is connected to the raised connecting parts by bolts, thereby completing the installation of the head-up display 100.

[0050] Specifically, a projection port is left at the top of the cover, and the projection port is arranged on the projection light path of the head-up display 100, so that the head-up display 100 can project the image onto the windshield assembly 20 for display, and a support groove is arranged on the first bracket 104 facing the user, and the support groove can be matched with the installation of the touch screen 301 to form an installation environment simulating a car. At this time, there is no need to set the shading assembly 40, but the user cannot view the interior, so an observation window can be opened above or below the support groove, and transparent glass can be placed on the observation window to facilitate the user to view the head-up display 100 inside the cover.

[0051] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
