Description

Technical Field

[0001] This invention relates to the field of projection lamp technology, specifically to automotive projection lamps, and more particularly to an automotive projection lamp with adjustable projection angle and direction. Background Technology

[0002] In an era of ever-increasing automotive intelligence, people are paying more attention to the human-computer interaction experience. This has led to the increasingly widespread application of ground projection lights, which are no longer just used for welcoming guests, but are gradually participating in signaling and even interactive scenarios. In current technology, ground projection lights basically project in a fixed direction and angle, and the projection area on the ground is also fixed.

[0003] Patent CN212273785U discloses a projection lamp that can rotate in all directions, which solves the problem that the current projection lamps cannot arbitrarily change the projection angle, which greatly increases the limitation of the venues where they can be used.

[0004] In existing technologies, vehicle-mounted projection lamp adjustment devices are mainly used to adjust the projection area offset caused by differences in vehicle body and installation tolerances; the projection range remains a fixed area. Existing modules that only adjust the projection direction or angle cannot meet the usage requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: in order to solve the technical problem that the projection lamp in the prior art can only adjust the projection angle or projection direction, the present invention provides a vehicle projection lamp with adjustable projection angle and direction. It can realize the synchronous adjustment of the projection angle and projection direction of the projection lamp component using only one power source, realize the switching of multi-direction and multi-angle projection, and meet the needs of different scenarios.

[0006] The technical solution adopted by this invention to solve its technical problem is: an adjustable projection angle and direction vehicle projection lamp, comprising: a projection lamp assembly, the projection lamp assembly including a rotating base, a projection lamp unit rotatably connected to the rotating base, a transmission frame fixedly connected to the projection lamp unit, and the other end of the transmission frame movably connected to a driven end. An active end is connected to the rotating base for power transmission, driving the rotating base to rotate the projection unit and the transmission frame around the central axis of the active end, thereby adjusting the illumination direction of the projection lamp unit; a fixed driven end, when the transmission frame rotates around the central axis of the active end, the other end of the transmission frame rotates around the driven end, driving the projection lamp unit to rotate around the central axis of the rotating base, thereby synchronously adjusting the illumination angle of the projection lamp assembly.

[0007] This invention relates to an adjustable projection angle and direction vehicle projection lamp, driven by a single power source. Through a rotating base and transmission frame, the projection lamp module can be synchronously adjusted in two different directions, while simultaneously controlling the projection lamp's posture and the projection area, thus meeting the projection needs of multiple scenarios.

[0008] Furthermore, in order to achieve the rotation of the transmission frame, the transmission frame extends horizontally to below the driven end and engages with the driven end.

[0009] Furthermore, in order to realize the transmission between the spur gear disk and the transmission frame, the driven end includes a fixedly installed spur gear disk, and the lower part of the spur gear disk meshes with the end of the transmission frame through a toothed structure.

[0010] Furthermore, in order to control the motion trajectory of the transmission frame, the tooth structure of the transmission frame is arranged in an arc shape, and the tooth structure part is located in the vertical plane where the spur gear disk is located.

[0011] Furthermore, in order to enable the projection lamp module to move with the rotating base, the projection lamp unit also includes a bracket, which is connected to the transmission frame by a key, and the bracket extends through the transmission frame into the rotating base and is connected to the bearing inside the rotating base.

[0012] Furthermore, in order to install the projection lamp unit, a projection module is provided on the upper surface of the bracket.

[0013] Furthermore, the projection module is a film lens, an MLA module, a micro DLP, a MEMS module, or a laser projection module.

[0014] Furthermore, in order to input power from the active end, the active end includes a worm gear reducer, the output shaft of which is arranged in a horizontal direction and connected to the rotating seat.

[0015] Furthermore, in order to fix the position of the projection lamp, the vehicle projection lamp also includes a base fixedly installed on the vehicle body, and both the active end and the driven end are fixed on the base.

[0016] Furthermore, to prevent the rotating seat from rotating eccentrically, the output shaft of the worm gear reducer is coaxially arranged with the spur gear disk.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention is an adjustable projection lamp for vehicles. By driving the rotating seat to rotate through the active end, the transmission frame is driven to rotate around the driven end, thereby synchronously adjusting the projection lamp unit in two directions to complete the adjustment of the projection posture and projection area. A single projection lamp unit can achieve projection in different directions and angles using only one power source.

[0018] 2. The present invention provides an adjustable projection angle and direction vehicle projection lamp. As an integral module, the vehicle projection lamp can be quickly assembled through a base, simplifying the transmission structure, reducing costs, and providing good adjustment effect.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0023] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] like Figures 1 to 3 As shown, an adjustable projection angle and direction vehicle projection lamp includes: a base 2, a projection lamp assembly 1, an active end, and a fixedly mounted driven end.

[0026] Specifically, the projection lamp assembly 1 includes a rotating base 11. A projection lamp unit is rotatably connected to the rotating base 11. A transmission frame 12 is fixedly connected to the projection lamp unit. The other end of the transmission frame 12 is movably connected to the driven end. The rotating base 11 has a split structure for easy assembly.

[0027] like Figure 1 As shown, the active end is connected to the rotating base 11 for power transmission, so as to drive the rotating base 11 to rotate the projection unit and the transmission frame 12 around the central axis of the active end, so as to adjust the illumination direction of the projection lamp unit.

[0028] Preferably, the driving end includes a worm gear reducer 3, the output shaft 33 of which is arranged in a horizontal direction and connected to the rotating seat 11.

[0029] When the worm gear reducer 3 is started, the worm 31 rotates, which in turn drives the worm wheel 32 to rotate. The output shaft 33 is mounted on the worm wheel 32 and synchronously drives the rotating seat 11 to rotate around the central axis of the output shaft 33. At this time, the projection lamp unit will also rotate synchronously, thus completing the adjustment of the projection direction of the projection lamp unit.

[0030] Since the transmission frame 12 also rotates synchronously, and the other end of the transmission frame 12 has a degree of freedom, when the transmission frame 12 rotates around the central axis of the driving end, the other end of the transmission frame 12 will also move around the driven end. Since the transmission frame 12 is fixedly connected to the projection lamp unit, the projection lamp unit rotates simultaneously around the central axis of the rotating seat 11, thus realizing the adjustment of the illumination angle of the projection lamp assembly.

[0031] Preferably, the driven end includes a fixedly mounted spur gear disk 4, the lower part of which meshes with the end of the transmission frame 12 via a toothed structure. The transmission frame 12 extends horizontally to below the driven end and meshes with it. The toothed structure of the transmission frame 12 is arranged in an arc shape, with the toothed portion located in the vertical plane where the spur gear disk 4 is located. Since the spur gear disk 4 is fixed, under the action of the toothed structure, one side of the transmission frame 12 will move along the trajectory of the toothed structure. Since the toothed trajectory of the transmission frame 12 is arc-shaped, the other side of the transmission frame 12 forms a motion trajectory around the central axis of the rotating seat 11 within the plane of the rotating seat 11. This achieves the axial rotation of the projection lamp unit, completing the adjustment of the projection angle of the projection lamp unit. The other state after adjustment is as follows... Figure 2 As shown. The projection angle can be adjusted by selectively setting other parameters such as the number of teeth in the toothed structure, thereby achieving control over different projection angles.

[0032] like Figure 4 As shown, the vehicle projection lamp in this embodiment can achieve oblique rear projection.

[0033] like Figure 5 As shown, the vehicle projection lamp in this embodiment can achieve side frontal projection.

[0034] like Figure 6 As shown, the vehicle projection light of this embodiment can also project in different ways, such as front projection and side projection. Figure 6 The projection orientations from left to right are front projection, side projection, and oblique rear projection.

[0035] Preferably, the projection lamp unit further includes a bracket 13, which is connected to the transmission frame 12 via a key. The bracket 13 extends through the transmission frame 12 into the rotating seat 11 and is connected to a bearing 14 within the rotating seat 11. The bearing 14 allows the projection lamp unit to rotate relative to the central axis of the rotating seat.

[0036] Preferably, the base 2 has supports on both the left and right sides, with the output shaft 33 rotatably connected to the support on the right side and the spur gear disk 4 fixed to the support on the left side. The output shaft 33 and the spur gear disk 4 are coaxially arranged. There is a gap between the base 2 and the rotating seat 11, which provides rotation space for the rotating seat 11 and avoids collision between the two.

[0037] Specifically, a projection module 15 is provided on the upper surface of the bracket 13. The attached diagram is only for illustrative purposes; the actual position of the projection module 15 can be adjusted according to projection requirements. The projection module 15 can be a film lens, MLA module, micro DLP, MEMS module, or laser projection module. The projection module is not limited to the above-mentioned modules and can also be other commonly used ones.

[0038] In summary, the present invention provides an adjustable projection angle and direction vehicle projection lamp that uses only one power source to achieve synchronous adjustment of the projection angle and direction of the projection lamp assembly, enabling switching between multi-directional and multi-angle projection to meet the needs of different scenarios.

[0039] The above description is based on the preferred embodiments of the present invention. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of the present invention. The technical scope of the present invention is not limited to the contents of the specification, but must be determined by the scope of the claims.
