Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to the field of vehicle accessories, and more particularly, to an angle-adjustable projection device for vehicles. 2. The Prior Arts In order to provide decorative ambient for the vehicle and lighting assistance for getting on and off the vehicle, while enhancing the sense of dignity or luxury, some models of commercial vehicles are equipped with projection lamps. When the projection lamps are activated, patterns or text images can be projected on the ground or at appropriate locations on the vehicle body. For example, a projection lamp can be installed at an appropriate position in the vehicle and connected to the vehicle's power supply. When the vehicle door is opened, the projection lamp is automatically started through sensing to project a pattern or text image onto the ground, thereby highlighting the visual sensory effects and auxiliary lighting at night or in dimly lit environments. The pattern or text may be a car brand's logo, trademark or any pattern and text. Conventional projection lamps are developed and designed based on different car models and sizes. In other words, projection lamps of specific specifications can only be installed on corresponding car models so that the projected image can obtain accurate focus. In addition, the size, direction and angle of the projected image are fixed and cannot be adjusted according to personal preferences. SUMMARY OF THE INVENTION A primary objective of the present invention is to provide an angle-adjustable projection device for vehicles, which allows the user to adjust the direction, angle and size of image projection according to personal preference, in particular a universal projection device that can be installed in various vehicles and can be adjusted in direction. The present invention provides an angle-adjustable projection device for vehicles, comprising a bracket assembly and a projection lamp assembly; wherein the bracket assembly comprises: a fixed bracket fixed to the vehicle; a movable bracket fixed to a first side surface of the fixed bracket and formed with a pair of cantilevers located on opposite sides, the pair of cantilevers extending to a second side surface of the fixed bracket through a hollow portion of the fixed bracket, and the ends of the pair of cantilevers being respectively provided with shaft sleeves; an adjustment screw rotatably arranged on the movable bracket, and the threaded portion of the adjustment screw extending out of the second side surface of the fixed bracket; a rubber ring sleeved on the adjustment screw and located between the screw head of the adjustment screw and the movable bracket; and a screw buckle arranged on the threaded portion of the adjustment screw; and the projection lamp assembly comprises: a housing provided with a shaft on opposite sides thereof, the shaft being rotatably matched to the shaft sleeve, one side of the housing being provided with an adjustment screw hole, and the adjustment screw hole matching with the adjustment screw; and a lens assembly arranged inside the housing to project an image out of the housing. When the adjustment screw is rotated, the projection lamp assembly can be controlled to rotate relative to the cantilever, thereby adjusting the direction and angle of the image projected by the projection lamp assembly. In a preferred embodiment, the movable bracket further comprises a plate body, the plate body is formed with a central hole, and a through hole and an arc-shaped slot hole located on opposite sides of the central hole, and the cantilever extends from the plate body; wherein, fixing screws pass through the through hole and the arc-shaped slot hole respectively and are locked into screw holes provided in the fixed bracket. Accordingly, after the projection lamp assembly is installed on the cantilever, the movable bracket can be rotated along the direction of the arc-shaped slot while loosening the fixing screw to adjust the position of the projection lamp assembly, and then the fixing screw is tightened to fix the projection lamp assembly in the adjusted position. A preferred embodiment of the present invention further comprises: a cap head, formed with a straight slot hole; wherein the adjustment screw passes through the straight slot hole and the center hole, and then is screwed into the adjustment screw hole. Accordingly, when the adjustment screw is loosened, the movable bracket can be moved along the extending direction of the straight slot to adjust the position of the projection lamp assembly, and then the adjustment screw is tightened to fix the projection lamp assembly in the adjusted position. Preferably, a slot can be formed on the upper side of the cantilever, and the shaft sleeve is arranged in the slot. Accordingly, the shaft sleeve can be easily installed on the cantilever. In a preferred embodiment, the projection lamp assembly further comprises: a lamp b
