Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figures 1 - 3 The utility model provides a technical solution: an advertising machine with a novel projection display structure, comprising a projection device 1, a display device 2 is arranged outside the projection device 1, a display screen 7 is arranged on the top of the projection device 1, the device can be flexibly installed, the projection device 1 can be installed above, below, on the left or right side of the display device 2 according to the needs of the on-site advertising machine, and can be installed on the rear windshield of a taxi or some outdoor billboards, a sound outlet 6 is arranged on one side of the projection device 1, and a switch 3 is arranged on one side of the projection device 1 located on the vertical plane of the display screen 7 and the sound outlet 6.

[0024] It should be noted that the device includes a projection device 1 and a display device 2. A display screen 7 is arranged on the top of the projection device 1. The display screen 7 is a low-energy, high-brightness LED display screen with a maximum brightness of 5000NIT and a power consumption of 2-3W. The display screen 7 has automatic photosensitivity control. It uses high brightness when the sun is high during the day, and when the ambient brightness is low at night, the display module will reduce the brightness. The information displayed on the display screen 7 is reflected on the display device 2 and presented in the driver's head-up field of view in the form of HUD. The display device 2 is a transparent reflector. The device changes the previous implementation method of the vehicle-mounted HUD, abandons the projection lamp, simplifies the device, and saves costs.

[0025] The housing of the projection device 1 includes a base 9 , a mounting box 10 and waterproof silica gel 11 . The top of the base 9 is fixedly connected with the mounting box 10 , and the waterproof silica gel 11 is provided at the connection between the base 9 and the mounting box 10 .

[0026] It should be noted that the display screen 7 of the projection device 1 of the present invention is set to be smaller, so that the screen displayed in the transparent screen 12 is smaller and the heat generated is lower. A waterproof silica gel 11 is set at the connection between the base 9 and the installation box 10. The waterproof silica gel 11 is fixedly connected to the base 9. After the base 9 and the installation box 10 are connected, the bottom and top of the waterproof silica gel 11 are respectively fitted with the base and the installation box 10, so that the connection between the base 9 and the installation box 10 is sealed, preventing moisture and external dust from entering the projection device 1.

[0027] The display device 2 includes a projection screen 12 and a mounting plate 13. A mounting plate 13 is integrally connected to the side wall of the base 9, and a projection screen 12 is mounted at the end of the mounting plate 13.

[0028] It should be noted that the screen of the projection screen 12 is small, and this display method has a lower heat output than traditional display screens, making it better able to adapt to high outdoor temperatures.

[0029] A reflective film 8 is plated on one side of the projection screen 12 facing the display screen 7, and the connection between the reflective film 8 and the projection screen 12 forms a reflective screen 14.

[0030] It should be noted that the coating of the reflective film 8 on the projection screen 12 only serves to reflect and is more heat-resistant. Compared with traditional electronic screen displays that require relatively high heat dissipation conditions in high-temperature environments, with many cooling devices removed or being unsuitable for high outdoor temperatures, the display screen 7 of this device will not affect the display effect at high temperatures.

[0031] The surface of the reflective screen 14 is provided with a concave curvature.

[0032] It should be noted that the reflective film 8 can play a reflective role, and the reflective screen 14 is provided with a certain curvature, making it easier for advertisers to view.

[0033] On the side of the projection device 1 away from the display screen 7, an HDMI interface 4 and a USB interface 5 are respectively provided.

[0034] It should be noted that the HDMI interface 4 and the USB interface 5 facilitate the connection with external device connectors.

[0035] The size of the projection screen 12 is twice that of the display screen 7.

[0036] It should be noted that the ratio of the projection screen 12 to the display screen 7 in this utility model can be adjusted according to the distance and angle, and the display screen 7 can be 1 - 3 times the size of the projection screen 12.

[0037] The projection screen 12 is an opaque or translucent screen.

[0038] It should be noted that in an environment with strong light, setting the projection screen 12 as a translucent or opaque screen can reduce the interference of external light on the projected image, thereby improving the clarity and visibility of the projection.
