[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0019] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.

[0020] Combination Figure 1-4As shown, the projection lamp includes a base frame 1, a bracket 2 is provided on the base frame 1, a radiator 3 is rotatably provided on the bracket 2 and there is a gap between the radiator 3 and the bracket 2, a PCBA 21 is provided on the bracket 2, a projection port 4 and a blocking port are respectively opened on the base frame 1, a lens module 6 and a dimming ball socket 7 are respectively provided in the radiator 3 and the lens module 6 is arranged toward the projection port 4, an internal threaded sleeve 8 is provided on the bracket 2, a dimming screw 9 is screwed into the internal threaded sleeve 8, a ball head 10 is formed on the top of the dimming screw 9 and the ball head 10 is located in the dimming ball socket 7, and the bottom of the dimming screw 9 is arranged toward the blocking port.

[0021] With the rapid development of the automobile industry, car lights are no longer just for the purpose of achieving lighting functions. People are pursuing higher and higher car styling and lighting effects, and more and more personalized customization, so interior atmosphere lights and exterior projection lights have appeared. Exterior car projection lights are generally installed under the door, on the rear or on the chassis, projecting a pure light surface, or a light surface with logos, Chinese characters or cartoon patterns.

[0022] Since projection lamps are extremely sensitive to manufacturing tolerances and installation requirements, this projection lamp adopts an adjustable design mechanism, which makes it easy to adjust the projection part after the entire lamp is installed to meet the pattern size and position designed during the design. This can reduce defective products caused by installation errors and manufacturing errors, better reduce costs and increase efficiency.

[0023] A matching plug 11 is inserted into the plugging port. The lower part of the dimming screw is hexagonal. In this embodiment, if you want to fine-tune the size and position of the pattern projected by the projection lamp, you only need to adjust the angle of the lens module. Specifically: open the plug, use a wrench, the top of the wrench is formed with an inner hexagonal groove, the top of the wrench is inserted into the bottom of the dimming screw as required, and then the wrench is rotated, the wrench drives the dimming screw to move up and down in the internal threaded sleeve, under the action of the dimming ball socket, the radiator rotates slightly relative to the bracket, and then drives the lens module to rotate, so as to achieve the size and position of the pattern projected by the lens module.

[0024] In actual situations, the specific number of turns of the dimming screw can be used to determine whether it is adjusted in place. The pitch of the dimming screw is also matched according to the design requirements, that is, dimming screws with different pitches are replaced and used. When the dimming screw is turned, the lens module will rotate to different angles accordingly.

[0025] like Figure 2 The bracket 2 is provided with a avoidance opening 12 corresponding to the lens module. The avoidance opening is used to avoid the lens module, so that the pattern projected by the lens module passes through the projection opening and is projected on the corresponding position.

[0026] In the above structure, PCBA is an integrated LED, which is an electronic component that receives signals, lights up LEDs, and is used in lens modules. Different patterns can be projected through the lens modules. PCBA is installed in the radiator, and the projector lamp dissipates heat through the radiator when it is working.

[0027] As a preferred structure, combined with Figure 1-3 A pair of left and right ear seats 13 are formed on the bracket 2. The projection lamp further includes a bottom frame 14. The radiator 3 is mounted on the bottom frame by means of fixing nuts. A shaft block 15 and an n-shaped clamp block 16 are formed on both sides of the bottom frame. The shaft block and the clamp block are rotatably connected to the ear seats on the same side, and the right ear seat is located in the clamp block. In the projection lamp, the radiator is rotatably mounted on the bracket by means of the bottom frame. The radiator is mounted on the top surface of the bottom frame by means of fixing nuts.

[0028] A pair of positioning posts 17 are provided on the bottom frame 14, and a pair of side blocks 18 are formed on the side walls of the radiator. Positioning grooves 20 are formed on the side blocks 18 corresponding to the positioning posts 17, and the fixing nuts are inserted into the side blocks. The fixing nuts (not shown in the figure) are screwed into the bottom frame and locked.

[0029] The radiator can be removed from the bottom frame. When the removed radiator needs to be installed on the bottom frame, the radiator is first placed directly above the bottom frame as required, and then placed on the bottom frame. At this time, the positioning columns on the same side are inserted into the positioning grooves for positioning before installation, and finally, a fixing nut is inserted into each side block, and the radiator is fixed to the bottom frame through the fixing nut.

[0030] In addition, the base frame and the bracket are installed in a buckle-connected manner, which makes it easy to install or disassemble the base frame and the bracket.

[0031] As a further preferred structure, Figure 3 A guide convex surface 19 is formed on the inner side of the right ear seat, and a guide opening (blocked in the figure) is opened on the inner layer of the clamping block, and the guide convex surface 19 is located in the guide opening 20.

[0032] When the radiator rotates in a small range, the clamping block rotates relative to the right ear seat. In this process, the guiding convex surface plays a role of limiting and guiding, so that the radiator is more stable during the rotation process.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
