Description

[0002] With the continuous advancement of car lighting technology, users have been pursuing better lighting effects, that is, brighter, farther, and wider, while not causing glare to oncoming vehicles or pedestrians, affecting driving safety. At present, car lights generally use matrix lighting ADB (Adaptive Driving Beam) technology with multiple LEDs (Light Emitting Diodes) arranged side by side. In high beam mode, this technology can intelligently detect the position of oncoming vehicles and turn off the LEDs in the corresponding area accordingly, thereby avoiding glare to the drivers of oncoming vehicles. Since this solution uses matrix LED pixels to illuminate the road surface, the entire light pattern is composed of many small light spots. However, due to errors in components and assembly processes, it is often difficult to achieve completely uniform distribution of light patterns, resulting in bright or dark lines in the light patterns. At the same time, the need to use multiple LED chips for matrix arrangement and precise control of lighting and extinguishing not only increases hardware costs, but also complicates the control process.

[0053] Another core of the present invention is to disclose a vehicle comprising the above-mentioned vehicle lamp.

[0055] Combination Figure 1-Figure 16The vehicle lamp disclosed in the present invention includes a mounting bracket 100, a first light output module 200 and a second light output module 300. The first light output module 200 is rotatably arranged on the mounting bracket 100 and is used to form a first light pattern 205; the second light output module 300 is arranged on the mounting bracket 100 and is used to form a second light pattern 301; when the first light output module 200 rotates to a first extreme position, the first light pattern 205 and the second light pattern 301 are spliced ​​to form a high beam light pattern, when the first light output module 200 rotates to the second extreme position, the second light pattern 301 completely overlaps with the first light pattern 205, and when the first light output module 200 rotates to a middle position between the first extreme position and the second extreme position, a first part of the second light pattern 301 overlaps with the first light pattern 205, and an anti-glare dark area is formed between the second part and the first light pattern 205.

[0056] Specifically, the vehicle is provided with detection mechanisms such as cameras that can detect the number and positions of oncoming vehicles. After the vehicle control system receives the oncoming vehicle information detected by the detection mechanism, it can control the first light output module 200 to rotate to a desired angle relative to the second light output module 300, so that the formed anti-glare dark area matches the position of the oncoming vehicle. Exemplarily, the first light type 205 can be a semicircular light type or a semi-elliptical light type or other approximately semicircular light type, and the second light type 301 can be a semicircular light type or a semi-elliptical light type or other approximately semicircular light type, so that the first light type 205 and the second light type 301 can be spliced ​​to form a circular or elliptical or approximately circular high beam light type. Figure 10-Figure 15 , Fig.10 The low beam light pattern formed by the vehicle lamp disclosed in the present invention, Fig.11 The high beam light pattern formed by the vehicle lamp disclosed in the present invention, Figure 12-Figure 15 The light patterns formed by the vehicle lamp disclosed in the present invention when there are oncoming vehicles of different numbers and distances.

[0057] Compared with the prior art, the headlight disclosed in the present invention forms a high beam light pattern and a low beam light pattern through the relative rotation between the first light emitting module 200 and the second light emitting module 300, and can realize dynamic adjustment of the dark area of ​​the oncoming vehicle area during the vehicle driving lighting process to avoid glare to oncoming drivers; the headlight disclosed in the present invention can adopt a conventional non-LED matrix light emitting scheme to emit light and form an anti-glare dark area, thereby reducing the problem of splicing uniformity of the light pattern lit by the LED matrix, ensuring the uniformity of the light pattern, and greatly reducing the number of LED chips, reducing hardware costs, and reducing the heat dissipation requirements of the headlights, with a simple and reliable structure.

[0058] In a specific embodiment disclosed in the present invention, the first light output module 200 is rotatably arranged on the mounting bracket 100 through the first driving assembly, and the first driving assembly includes a first driving member 210 and a first transmission gear 212. The first driving member 210 is arranged on the mounting bracket 100, and the output shaft of the first driving member 210 is connected to the first output gear 211 in a transmission manner. The first transmission gear 212 is arranged and connected with the first light output module 200 on the same (rotation) axis, and is meshed with the first output gear 211 for transmission. When the first driving member 210 is started, the first output gear 211 can drive the first transmission gear 212 to rotate, and then drive the first light output module 200 to rotate, so as to realize the position movement of the first light pattern 205 relative to the second light pattern 301. Among them, the first driving member 210 can be a driving motor.

[0059] In order to facilitate the rotation of the first light output module 200 on the mounting bracket 100, a first mounting bearing is provided on the mounting bracket 100, and the first light output module 200 is passed through the first mounting bearing. The first mounting bearing ensures the position accuracy and stability of the first light output module 200 rotating on the mounting bracket 100.

[0060] Combination Figure 10-Figure 15 The rotation axis of the first light output module 200 is set on the light-dark cutoff line of the first light pattern 205, preferably passing through the center of the first light pattern 205, so that when the first light output module 200 rotates around the rotation axis, the first light pattern 205 can rotate around the center point of the first light pattern 205, thereby accurately controlling the distribution and shape of the car light pattern and optimizing the light pattern effect.

[0061] According to a further optimization scheme, the second light emitting module 300 is rotatably disposed on the mounting bracket 100 through a second driving assembly, and both the first light emitting module 200 and the second light emitting module 300 can rotate, so that the vehicle lamp can achieve more light emitting patterns, meet the lighting effects under more road conditions, and improve the safety of lighting.

[0062] Specifically, in one embodiment, the second driving assembly includes a second driving member 310 and a second transmission gear 312. The second driving member 310 is arranged on the mounting bracket 100, and the output shaft of the second driving member 310 is transmission-connected with a second output gear 311. The second transmission gear 312 is coaxially arranged and connected to the second light output module 300, and meshes with the second output gear 311 for transmission. When the second driving member 310 is started, the second output gear 311 can drive the second transmission gear 312 to rotate, thereby driving the second light output module 300 to rotate, thereby realizing the position movement of the second light type 301.

[0063] The second driving member 310 may be a driving motor. The rotation axis of the second light output module 300 is arranged on the light-dark cutoff line of the second light pattern 301, preferably passing through the center of the second light pattern 301, so that when the second light output module 300 rotates around the rotation axis, the second light pattern 301 can rotate around the center point of the second light pattern 301, thereby accurately controlling the distribution and shape of the light pattern of the headlight and optimizing the light pattern effect.

[0064] Furthermore, the rotation axis of the first light output module 200 coincides with the rotation axis of the second light output module 300, and preferably the center points of the first light pattern 205 and the second light pattern 301 coincide, to ensure that the light output pattern formed by the headlights can cover as much road area as possible, thereby improving driving safety.

[0065] In order to facilitate the rotation of the second light output module 300 on the mounting bracket 100, a second mounting bearing is provided on the mounting bracket 100, and the second light output module 300 is inserted into the second mounting bearing. The setting of the second mounting bearing reduces the rotation resistance of the second light output module 300 and improves the rotation accuracy and stability of the second light output module 300.

[0066] Combination Figure 5 The mounting bracket 100 may be an integrated bracket structure, on which the first light output module 200 and the second light output module 300 are disposed together, which has a simple structure and is easy to install. Fig. 9 The mounting bracket 100 includes a first bracket 101 and a second bracket 102. The first bracket 101 is rotatably arranged in the lamp housing, and the first light output module 200 is arranged on the first bracket 101; the second bracket 102 is arranged in the lamp housing, and the second light output module 300 is arranged on the second bracket 102; the first bracket 101 and the second bracket 102 are independent of each other, and the power output end of the third driving member 103 is connected to the first bracket 101, and can drive the first bracket 101 to rotate to adjust the light output angle of the first light output module 200, so that the center of the circle and the rotation axis of the first light type 205 and the second light type 301 coincide.

[0067] Specifically, the third driving member 103 can be an electric push rod. The fixed installation site of the first bracket 101 is hinged to the lamp housing through a ball joint, and the third driving member 103 is hinged to the movable installation site of the first bracket 101 through a ball joint. The third driving member 103 can push and pull the movable installation site of the first bracket 101 to rotate the first bracket 101 around the fixed installation site to achieve vertical and / or horizontal installation angle adjustment. The adjustment structure and adjustment principle of the third driving member 103 and the first bracket 101 can specifically refer to the adjustment structure and adjustment principle of the dimming bracket of the vehicle lamp lighting module in the prior art. The second bracket 102 can also use the adjustment structure and adjustment principle of the dimming bracket to adjust the light output angle, which will not be repeated here.

[0068] Combination Figure 5 , a lampshade 120 is provided on the mounting bracket 100 through the module decorative frame 110. Figure 2 and Figure 7 In one embodiment, the first light output module 200 includes a lens holder, an inner lens 202, a heat sink 204 and a light board 201, combined with Figure 8 After the lamp beads on the lamp board 201 emit light, the light is reflected and refracted by the inner lens 202 to the outer lens 203, and finally emitted from the lampshade 120 after passing through the outer lens 203, forming a semicircular or other shaped first light pattern 205, and the horizontal and vertical HV light-dark cutoff lines of the first light pattern 205 have good sharpness. The first light output module 200 can also use the light output scheme of the light source, the condenser, the light-dark cutoff line baffle and the outer lens 203 to emit light, and it is only necessary to ensure that the light-dark cutoff lines of the first light pattern 205 are clear and the light pattern is uniform. The second light output module 300 can use the same structure as the first light output module 200 to emit light, which will not be repeated here.

[0069] The first light output module 200 and / or the second light output module 300 can also be used in combination with other modules of the vehicle lamp to meet the driving lighting requirements of different users. Fig.16 shown.

[0070] The vehicle lamp disclosed in the present invention performs light pattern splicing through mechanical rotation of the first light emitting module 200 and the second light emitting module 300 to form a dynamic light emitting pattern, which can realize the formation of an anti-glare dark area in the oncoming vehicle area and the dynamic change of the size of the anti-glare dark area.

[0071] The vehicle disclosed in the present invention includes the above-mentioned headlights, so it also has the above-mentioned structure and beneficial effects. Other structures refer to the prior art and will not be described in detail here.

[0072] The above description of the disclosed embodiments enables professionals and technicians in the field to implement or use the present invention.
