Description

Technical Field

[0001] This utility model relates to the field of projector technology, and in particular to a flip-type vehicle-mounted projector. Background Technology

[0002] Head-up displays are becoming increasingly widely used in vehicle driver assistance systems. Their function is to allow drivers to see the information on the display without having to look down at the instrument panel, while keeping their heads up at all times. This helps prevent traffic accidents caused by driver inattention during driving.

[0003] Most existing HUD projectors have their screens fixedly connected to the base and cannot be flipped and closed onto the base when not in use. There is an urgent need for a flip-type vehicle projector. Utility Model Content

[0004] This invention provides a flip-type vehicle-mounted projector to solve the problem that in the prior art, most HUD projectors have their screens fixedly connected to the base and cannot be flipped to cover the base when not in use.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] A flip-type vehicle-mounted projector, comprising:

[0007] The base portion includes a motherboard base and a pedestal disposed at the rear end of the motherboard base, and the motherboard is installed inside the motherboard base.

[0008] An electrically operated rotating screen unit is mounted on the front end of the motherboard base;

[0009] The projection lens is movably mounted on the base.

[0010] In one specific implementation, the front end of the motherboard base is provided with a mounting slot for mounting the motorized flip screen, the upper edge of the motherboard base is provided with a sealing strip, the upper surface of the motherboard base is provided with a positioning groove, the interior of the motherboard base is provided with a cavity for mounting the motherboard, the lower surface of the motherboard base is provided with a heat dissipation vent, and the lower end of the motherboard base is provided with rubber feet.

[0011] In one specific implementation, the base has a mounting cavity in the middle for inserting and mounting the projection lens, a vent on the back of the mounting cavity, and a movable slot at the upper end of the mounting cavity.

[0012] In one specific implementation, the electrically rotating screen unit includes a transparent screen installed in the mounting slot and a servo motor installed on one side of the mounting slot.

[0013] In one specific implementation, the transparent screen includes a screen body and a connecting shaft end disposed at the lower end of the screen body. The connecting shaft end is rotatably mounted in the mounting slot, and the output end of the servo motor is connected to one end of the connecting shaft end.

[0014] In one specific implementation, the projection lens unit includes a projection lens that can be movably installed in the mounting cavity and a positioning member disposed on the upper end of the projection lens. The projection lens is provided with a transmission line electrically connected to the motherboard, and the projection lens is positioned in the positioning groove.

[0015] In one specific implementation, the positioning element includes a threaded post fixedly disposed at the end of the upper surface of the projection lens, the threaded post being inserted into the movable slot, and a locking nut being threaded onto the threaded post.

[0016] The beneficial effects of this utility model are:

[0017] The motorized flip screen is installed at the front end of the motherboard base. When in use, the motorized flip screen can automatically flip open, and the screen projection lens installed on the base can project the image onto the motorized flip screen for display. When not in use, the motorized flip screen flips and closes on the base. The ability to flip and close the screen greatly reduces obstruction of the view when not in use, making it more convenient.

[0032] Reference Figure 1-5 As shown, this utility model provides a flip-type vehicle-mounted projector, comprising:

[0033] The base portion 100 includes a motherboard base 110 and a pedestal 120 disposed at the rear end of the motherboard base 110. The motherboard base 110 houses the motherboard 130.

[0034] The motorized flip screen 200 is mounted on the front end of the motherboard base 110.

[0035] The projection lens unit 300 is movably mounted on the base 120.

[0036] The motorized flip screen 200 is installed at the front end of the motherboard base 110. When in use, the motorized flip screen 200 can automatically flip open, and the screen projection lens 300 installed on the base 100 can project the image onto the motorized flip screen 200 for display. When not in use, the motorized flip screen 200 flips and closes on the base 100. The ability to flip and close the screen greatly reduces obstruction of the view when not in use, making it more convenient.

[0037] As a further preferred embodiment of the above-described embodiment, the front end of the motherboard base 110 is provided with a mounting slot 111 for mounting the motorized flip screen 200, the upper edge of the motherboard base 110 is provided with a sealing strip edge 112, the upper surface of the motherboard base 110 is provided with a positioning groove 113, the interior of the motherboard base 110 is provided with a cavity 116 for mounting the motherboard 130, the lower surface of the motherboard base 110 is provided with a heat dissipation vent 114, and the lower end of the motherboard base 110 is provided with rubber feet 115.

The connecting shaft end 212 is rotatably installed in the mounting slot 111, and the output end of the servo motor 220 is connected to one end of the connecting shaft end 212. When the covered transparent screen 210 needs to be flipped open, the servo motor 220 drives the connecting shaft end 212 to rotate in the opposite direction, causing the transparent screen 210 to flip open.

[0041] As a further preferred embodiment of the above-described embodiment, the projection lens unit 300 includes a projection lens 310 that is movably installed in the mounting cavity 121 and a positioning member 320 disposed on the upper end of the projection lens 310. The projection lens 310 is provided with a transmission line 311 that is electrically connected to the motherboard 130, and the projection lens 310 is positioned in the positioning groove 113.
