[0034] The warning image projection device of the present invention can be assembled on the vehicle handle 800. The projection component 300 can output projection light and the projection light is emitted from the light outlet 220. The projection light can form a light spot of the projection image on the vehicle's driving path. During the riding process, the user can operate the operating component 400 according to his or her own needs.

The light emitted by the LED lamp bead is processed by the display control chip 320 to form an image, and then amplified by the imaging lens group 330, and then emitted from the light outlet 220 to form a light spot pattern on the ground.

[0039] Specifically, the imaging lens group 330 can be composed of a combination of a concave lens and a convex lens, or can include a Fresnel lens, etc., and can be selected according to the actual needs of the user.

[0040] In some embodiments of the present invention, Figure 1 - Figure 3 As shown, the operating component 400 includes a switch operating member 410 and a switching operating member 420, both of which are arranged on the shell 200. The switch operating member 410 is connected to the light source member 310 to control the light source member 310 to turn on and off. The switching operating member 420 is connected to the display control chip 320 to drive the display control chip 320 to switch between at least the first projection state and the second projection state.

[0041] Among them, the switch operating part 410 and the switching operating part 420 can be push-button switches, and the power supply supplies power to the light source part 310 through the switch operating part 410.

[0043] Generally speaking, the vehicle handle 800 is in the form of a long tube, and a mounting port may be provided at the end of the vehicle handle 800. The shell 200 may be partially inserted into the vehicle handle 800 through the mounting port, and the light outlet 220 is exposed from the vehicle handle 800 and faces the ground. After the projection light is emitted from the light outlet 220, a light spot may be formed on the ground.

[0044] In some embodiments of the present invention, the light source component 310, the display control chip 320 and the imaging lens group 330 are arranged along the length direction of the shell 200, the light outlet 220 is set on the peripheral wall of the shell 200, and the warning image projection module 100 also includes a reflector 600, which is set in the shell 200 and located in the inner cavity 210. The reflector 600 corresponds to the light outlet 220, and the projection light is reflected by the reflector 600 and then emitted from the light outlet 220.

[0045] The projection light emitted by the light source 310 is transmitted along the length direction of the housing 200 and irradiated by the reflector 600 . The reflector 600 reflects the projection light and changes the transmission direction of the projection light so that the projection light can be emitted from the light outlet 220 .

[0046] In some embodiments of the present invention, the reflector 600 has a reflective mirror surface, and the incident angle of the projected light on the reflective mirror surface is 45°.

[0047] The reflector 600 can be selected from conventional reflective lenses, which have a reflective mirror surface. The reflective lens is tilted relative to the length direction of the shell 200, with a specific tilt angle of 45°, so that the projection light can be emitted directly from the light outlet 220 located on the peripheral wall of the shell 200.

[0048] In some embodiments of the present invention, the warning image projection module 100 also includes an energy storage component 720, which is arranged in the shell 200 and located in the inner cavity 210, and the energy storage component 720 is connected to the projection assembly 300 to power the projection assembly 300, and the shell 200 is provided with a charging interface 710, and the charging interface 710 is used to connect to a power supply, and the charging interface 710 is connected to the energy storage component 720, and the light outlet 220 is arranged near the head end of the shell 200, and the charging interface 710 is arranged near the tail end of the shell 200.

[0049] like Figure 3 As shown, the energy storage component 720 can be a battery, multiple button batteries connected in series, etc., which are usually in the shape of a long strip and can be arranged along the length direction of the inner cavity 210. The charging port can be a conventional USB port. A charging and discharging circuit board is provided in the shell 200, and the power supply is connected to the charging port. The energy storage component 720 can be powered by the charging and discharging circuit board, and the energy storage component 720 can then power the projection component 300 through the charging and discharging circuit board.

[0050] The charging port is facing away from the light outlet 220, and the warning image projection module 100 is installed on the vehicle handle 800. The light outlet 220 at the front end of the shell 200 is exposed to the vehicle handle 800, while the charging interface 710 at the rear end of the shell 200 is hidden in the vehicle handle 800, which can prevent dust and moisture from corroding the charging interface 710, and it is not easy for external objects to collide with the charging interface 710 and cause damage to the charging interface 710.

[0051] In some embodiments of the present invention, Figure 4 As shown, there are two warning image projection modules 100. In the second projection state of one of the warning image projection modules 100, the turning pattern 350 is a left-turn pattern, and in the second projection state of the other warning image projection module 100, the turning pattern 350 is a right-turn pattern.

[0052] One of the warning image projection modules 100 can be installed on the left side of the vehicle handle 800, and the other warning image projection module 100 can be installed on the right side of the vehicle handle 800. Thus, when it is necessary to turn left, the user manipulates the operating component 400 of the warning image projection module 100 on the left to enter the second projection state and project a left-turn pattern. When it is necessary to turn right, the user manipulates the operating component 400 of the warning image projection module 100 on the right to enter the second projection state and project a right-turn pattern.
