Description

Technical Field

[0001] The invention belongs to the technical field of vehicle lamps, and in particular relates to a self-balancing lighting module, a vehicle lamp and a vehicle. Background Art

[0002] A self-balancing lighting module is provided at the front end of a two-wheeled vehicle (such as a motorcycle, an electric motorcycle, an electric car, etc.), and the self-balancing lighting module can provide lighting in a poorly lit environment, thereby providing the driver with a clear view of the road ahead. However, when turning, the self-balancing lighting module will turn its head to the inside of the turn together with the vehicle, and when turning, the lighting distribution of the self-balancing lighting module will also rotate with the self-balancing lighting module, which will cause a blind spot in the front of the inside, especially at night when the road conditions in front of the inside of the turn are not clear, and there will be glare on the outside of the turn, which may cause danger.

[0003] like Figure 1 It is a schematic diagram of the lighting light distribution rotating with the self-balancing lighting module when turning. When the vehicle turns at an angle of d, the visual lighting light distribution also deflects at an angle of d. In the lighting light distribution light distribution light distribution pattern, the "HV" point is the horizontal line through the reference center to the vertical line of the lighting light distribution pattern, which is used to determine the center position of the lighting light distribution and the shape of the light type. 101 and 102 represent the end line and center line of the road respectively. The inner side 103 of the lighting light distribution and the outer side 105 of the lighting light distribution tilt inward and outward respectively with the turn, resulting in a lightless blind area in the corner area 104, and the outer side 105 of the lighting light distribution tilts outward, and its light distribution exceeds the upper side of the H horizontal line, which may cause dazzle to oncoming vehicles.

[0004] The existing patent EP3880548A1 discloses a motorcycle headlight, in which the reflector and control lens of the self-balancing lighting module unit are supported in the lamp housing so that they can rotate along the optical axis direction, thereby correcting the light distribution tilt caused by the self-balancing lighting module. However, since the reflector, lens, light source, etc. are all moved to correct the tilt of the light distribution, due to the limited load drive of the motor, in order to improve the service life of the motor and the stability of the drive, it is inevitable to use multiple gears and bearings set on the support base to support the reflector, etc. This will cause the volume of the self-balancing lighting module to increase, and the gear bearings will introduce additional mechanical transmission links.

[0005] The existing patent JP1991238701A discloses a self-balancing lighting module variable light distribution device, which blocks part of the light from the light source by placing a visor on the front opening side of the reflector, irradiates the light in a predetermined pattern, and can use the visor to change the direction, so that this type of headlight is compact, lightweight and stable. The light emitted from the filament to the upper half of the reflective surface of the reflector is first reflected by the reflective surface, converged at the second focus, and travels downward to the lens at an angle from the lower side. Therefore, the light C is blocked by the visor and does not enter the projection lens 32. The light emitted from the filament to the approximately lower half of the reflective surface of the reflector is reflected by the reflective surface and converged at the second focus, from which it travels upward to the lens, and then is refracted by the lens and projected below the H line. This transmission method of the prior art may introduce additional dynamic response delays due to factors such as gear meshing, bearing friction, and the natural frequency of the mechanical system. Summary of the invention

[0006] In view of the above-mentioned prior art, the purpose of the present invention is to provide a self-balancing lighting module, aiming to solve the following problems: 1. In the existing self-balancing lighting modules or headlights, the rotating parts that need to be driven by the motor are heavy, generally including a structure composed of a heat sink, a reflective bowl, a PCB board, a light source, and even a lens, which will cause the motor to be overloaded and reduce sensitivity, and long-term operation will also affect the reliability of the structure. 2. Since the rotating parts that need to be driven inside the existing self-balancing lighting modules or headlights are too large, transmission structures such as gears, racks, and bearings must be introduced to increase the load of the motor. However, this transmission method may introduce additional dynamic response delays due to factors such as gear meshing, bearing friction, and the natural frequency of the mechanical system.

[0007] In the first aspect, the present invention provides a self-balancing lighting module for generating lighting light distribution, comprising a supporting base, a motor, a heat sink, a PCB board, a light source, an optical component, a shading bracket, a first bracket and a lens, wherein one end of the motor is fastened to the supporting base, and further comprising a light-shaped baffle and a baffle bracket, wherein the light-shaped baffle is located between the baffle bracket and the lens, and the lens is a spherical center lens, the light-shaped baffle is directly or indirectly fixedly connected to one end of the baffle bracket, and the other end of the baffle bracket is fixedly connected to the output shaft of the motor, so that the light-shaped baffle rotates around the central optical axis of the lens, thereby changing the lighting light distribution.

[0008] Preferably, the baffle bracket is formed integrally with the light-type baffle, and is fixed to the output shaft of the motor by screws.

[0009] Preferably, the light-shaped baffle is close to the focal position of the lens, has an upper edge and a lower edge, and the size of the light-shaped baffle at least covers half of the lens.

[0010] Preferably, the structure of the lens is as follows: the cross sections obtained by cutting the lens from a plane perpendicular to the central optical axis X direction are all circular.

[0011] Preferably, the support base is formed integrally with the heat sink.

[0012] Preferably, the cross-section of the support base is C-shaped, forming a accommodating cavity wrapped on three sides, and the upper edge and the lower edge are parallel to each other; the motor is fixed to the lower edge of the support base.

[0013] Preferably, the baffle bracket and the light-shaped baffle are integrally formed into an accommodating cavity, which half-encloses the heat sink, the PCB board, the light source and the optical components.

[0014] Preferably, the self-balancing lighting module also includes a gyroscope and a control unit, wherein the gyroscope is arranged on the control unit, and is used to detect the tilt angle of the self-balancing lighting module and feed back the tilt angle to the control unit, and the control unit is used to receive the tilt angle fed back by the gyroscope and control the motor to rotate the same angle in the opposite direction of the rotation angle.

[0015] In a second aspect, the present invention further provides a vehicle lamp, comprising a lamp housing, a lampshade and the self-balancing lighting module as described in the first aspect, wherein the lamp housing is fastened to the bottom housing and defines a accommodating cavity together with the lampshade, and the accommodating cavity is used to accommodate the self-balancing lighting module.

[0016] In a third aspect, the present invention further provides a vehicle, comprising a vehicle body and the vehicle light as described in the second aspect, wherein the vehicle light is fastened to the vehicle body.

[0017] The beneficial effects of the present invention are as follows: 1. The light baffle is very light. Compared with the existing method of driving the entire lighting unit or driving the lens to pivot the lighting light distribution, the present application only needs to drive the light baffle with a very light mass to achieve the same effect, and the loss of the motor is very small.

[0018] 2. The existing technology is generally a system in which the motor output shaft drives the large gear through a small gear, which introduces an additional mechanical transmission link. This transmission method may introduce additional dynamic response delays due to factors such as gear meshing, bearing friction, and the natural frequency of the mechanical system. In contrast, the method in which the motor directly drives the light-type baffle can provide faster dynamic response because these mechanical transmission links are omitted. Direct-drive systems generally have higher system rigidity, which means that for a given input, the system produces less displacement or rotation, allowing for more precise control. High-rigidity systems generally have faster responses because they are more resistant to load changes.

[0019] 3. The light baffle is located between the first bracket and the lens, that is, the torque driven by the motor will be smaller than the outermost lens driven by the motor. The self-balancing lighting module is fixed at the front end of the vehicle. When the vehicle is driving, the internal structural parts of the self-balancing lighting module often need to withstand 10G vibration. The farther the lens is driven by the motor, the greater the driving force needs to be, which will also cause greater loss to the motor. At the same time, the bracket connecting the outermost lens and the motor is also relatively long, which may cause grinding or even breakage under long-term vibration.

[0020] 4. The lighting light distribution is formed by the lighting unit, which does not rotate by itself. The function of the light pattern baffle is to block part of the light pattern to form a lighting light distribution with a light cutoff line parallel to the ground. When the lighting unit rotates as the vehicle turns, the lighting light distribution also deflects. At this time, in order to continue to maintain the lighting light distribution with a light cutoff line parallel to the ground, the light pattern baffle rotates in the opposite direction driven by the motor.

[0021] 5. This solution also provides a high-beam and low-beam switching solution. When the high-beam lamp beads are on, the light-shaped baffle no longer rotates around the central optical axis of the lens to provide high-beam lighting. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0029] In addition, the motor described in the embodiment, also known as an electric motor, is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor usually includes a stator (i.e., a fixed end) and a rotor (i.e., an output shaft), the stator includes a stator core and a coil winding wound on the stator core, the rotor includes a rotating shaft and a rotor core sleeved on the rotating shaft, and a permanent magnet is provided on the outer edge of the rotor core. Example

[0030] like Figure 2 and Figure 3As shown, the support base 1 and the radiator 3 are an integrally formed aluminum profile, which is formed by extending the cross section and has a plurality of uniform heat dissipation fins. When the light source 5 is turned on, it emits light and generates heat, and the heat is transferred to the radiator 3 through the PCB board 4, and then the heat is dissipated through the heat dissipation fins, thereby increasing the practical life of the light source 5. Preferably, thermal conductive silicone grease can be applied between the PCB board and the radiator 3 to improve the thermal conductivity efficiency. The optical component 6 is a small lens that can collimate and focus the light emitted by the light source 5 and transmit it to the lens 9. The optical component 6 is fixed to the PCB board by screws. The small lens is a biconvex lens, and the light source 5 generates a focus on the other side of the small lens, and the light-shaped baffle 10 is located at the focus. The shading bracket 7 is used to block part of the light refracted from the non-collimated focusing part of the small lens, and is fixed to the PCB board by screws. In fact, the shading bracket 7 and the small lens are used in combination in a direct optical solution. If the optical component is a reflective bowl, the shading bracket 7 is not needed, because the reflective bowl can collimate and reflect the light at the focus of the reflective bowl, while other light will be reflected to other paths and will not be refracted from the lens 9 to affect the final light pattern.

[0031] The light baffle 10 and the baffle bracket 11 are integrally formed plastic parts, which are fixed to the output shaft of the motor 2 by screws, and the other end of the motor is fixed to the support base 1. Specifically, the motor includes a DC motor, an AC motor, a stepper motor, a servo motor, a brushless motor, etc. The thickness of the motor in this embodiment is greater than the thickness of the PCB board, the optical component 6 and the light shielding bracket 7, so the light baffle 10 and the baffle bracket 11 are at the same height. In fact, if a smaller motor is selected, it is necessary to adapt to change the structure of the baffle bracket 11, such as a right-angle structure. The light baffle 10 is located between the lens 9 and the light shielding bracket 7, has an upper edge and a lower edge, and the size of the light baffle 10 covers at least half of the lens 9. Since the light pattern formed by the lighting module is similar to the shape of "a bowl full of rice overflowing", when the lighting module is tilted by 10°~30°, the light baffle 10 is tilted in the opposite direction at the same angle to block the overflowing light pattern, so from the visual effect, the light pattern is a low beam light pattern that complies with regulations, and the cutoff line is always parallel to the road surface.

[0032] Finally, the lens 9 is fixed to the lens bracket 8 by means of buckles, and the lens bracket 8 is fixed to the heat sink 3 by means of screws.

[0033] In addition, the structure of the lens in this embodiment is as follows: the lens 9 is a spherical center lens, that is, a four-part lens obtained by cutting the lens 9 with any two mutually perpendicular surfaces, and the curvatures of the four-part lenses are consistent, that is to say, the lens 9 is a standard curved circular lens or a spherical center lens. In this way, no matter which half of the lens is used for the outgoing light, the light pattern is the same, so that it can be ensured that the lighting light distribution formed by the lighting unit and the lens does not change substantially without rotating the lens, the cutoff line will not be blue, and the light pattern will not be distorted. However, since the spherical center lens needs to add a flange during installation, the cross-section obtained by cutting the lens from a surface perpendicular to the center optical axis X direction may not necessarily be circular. And additional light patterns will be generated, but they do not affect the lighting light distribution of this application, and they all belong to the protection scope of this application. Example

[0034] like Figure 4 and Figure 5 As shown, the motor 2 is fixed on the lower edge 13 of the support base 1. The cross-section of the support base 1 is C-shaped, forming a three-sided wrapped accommodating cavity, and the upper edge 12 and the lower edge 13 are parallel to each other. The radiator 3 and the PCB board 4 are of the same structure, fixed at the upper edge 12 of the support base 1 by screws, which increases the thickness of the PCB board 4 in the height direction and improves the heat dissipation efficiency of the PCB board 4. The baffle bracket 11 and the light-type baffle 10 form an accommodating cavity that half-wraps the radiator 3, PCB board 4, light source 5, optical component 6 and shading bracket 7, and has a certain gap to prevent interference when the baffle rotates. The other structures are basically the same as those in Example 1 and will not be described in this embodiment. Example

[0035] like Figure 6 and Figure 7 As shown, the specific structure is as follows: the radiator 3 is located in the middle of the support base 1 and is trapezoidal in shape. The low beam PCB board 41 is located at the top of the radiator 3, and the high beam PCB board is located at the waist of the radiator 3, and both are fixed to the radiator by screws. The low beam reflector 61 and the high beam reflector 62 are positioned on the corresponding PCB boards by screws. The support base 1 extends downward to form a platform for fixing the motor 2. The light-shaped baffle 10 is formed integrally with the baffle bracket 11 and is fixed to the output shaft of the motor through the baffle bracket 11. The first bracket 8 and the second bracket 12 are both hollow structures, and the diameter of the first bracket is smaller than the diameter of the second bracket. The first bracket 8 includes an inward first flange 81 and a first skirt 82. The second bracket 12 includes an inward second flange 121 and a second skirt 122. The lens 9 includes a main body 91 and a third flange 92. The first flange 81 and the second flange 122 are fixed to the support base 1 together with screws. The first skirt 81 is used to support the third flange 92 of the lens 9 and cooperate with the second skirt 122 to press and fix the lens 9.

[0036] In this embodiment, the low beam light source 51 is attached to the focus of the low beam reflector 61 having a reflective surface or a total reflective surface. The shape of the low beam reflector is similar to a quarter of a sphere, and its inner side is a reflective surface or a total reflective surface. Part of the light reflected by the low beam reflector 61 is directly incident on the lens 9, and is collimated by the lens and emitted forward to form an illumination light distribution. Specifically, Figure 8 In the light path diagram shown, the lower half of the reflective surface inside the low beam reflective bowl 61 converges to the other focus of the low beam reflective bowl 61, and enters the lens 9 downward without being blocked by the light pattern baffle 10, and then is refracted out by the lens 9 to form a low beam light pattern with a cutoff line a. The upper half of the reflective surface inside the low beam reflective bowl 61 is blocked by the light pattern baffle 10. The center of the upper edge of the light pattern baffle 10 is located on the central optical axis of the lens, and the upper edge is a line perpendicular to the central optical axis when viewed from the direction of the central optical axis. The upper edge is located at the other focus of the low beam reflective bowl 61. This is because if the lens directly deflects the light emitted by the light source, the required light spot distribution with a cutoff line is formed on the target surface. This type of optical system is very sensitive to the size of the light emitting area of ​​the light source, and it must be required that the light source can be equivalent to a point light source, otherwise it will cause the deterioration of the light spot near the cutoff line.

[0037] like Fig. 9 As shown, without the light pattern baffle 10, the low beam pattern formed by the lighting module is similar to a "bowl filled with rice overflowing", and the cut-off line a is located near the 0 axis of the H line. The light pattern on the cut-off line will be blocked by the light pattern 10, thereby forming a low beam pattern that complies with regulations. When the lighting module tilts due to the two-wheeled vehicle turning, causing the low beam pattern to tilt, at this time the motor 2 will drive the light pattern baffle 10 to rotate in the opposite direction to form a new cut-off line a.

[0038] The light emitted by the high-beam light source 52 is almost reflected by the high-beam reflective bowl 62 which is approximately in the shape of a funnel, and then refracted by the lens 9 to form an approximately circular high-beam light pattern, so there is almost no change.

[0039] Specifically, the lens can be an asymmetric double free-form surface, which can effectively suppress the dispersion phenomenon caused by the deflection of light emitted at a large angle and stabilize the color temperature distribution of the illumination surface.

[0040] In this solution, since the light baffle to be driven is light in weight, a smaller driving source can be used. The light baffle is a relatively small component, so there is no great shaking during movement, and the operation of changing the light distribution direction can be performed very stably, and the light distribution direction can be changed. Directly using the output shaft of the motor as the drive can improve positioning accuracy. It is light in weight, and the combined weight of the reflective bowl, light source, and PCB is less than the weight of the radiator and the lens. Example

[0041] like Fig.10 and Fig.11 As shown, the low beam light source 53 and the high beam light source 54 are shown on a PCB board. When the low beam mode is displayed, the low beam light source 53 is on, and the high beam light source 54 is off. The light pattern baffle 10 is driven by the motor to rotate around the central optical axis of the lens to form a cut-off line parallel to the ground, thereby blocking the light above the cut-off line, including the high beam light pattern. When the high beam light source 54 is turned on, the high beam mode is displayed, and the light above the cut-off line cannot be blocked. Therefore, the motor drives the light pattern baffle 10 to rotate 180° under the control of the drive board, as shown in FIG. Fig.11 As shown, the high beam mode can be executed at this time. Example

[0042] like Fig.10 , 12 As shown in FIG. 13 , this embodiment shows that the low beam light source 53 and the high beam light source 54 are on a PCB board. When the high beam light source is turned on to perform the high beam mode, the light baffle 10 can stand up and rotate 90° under the drive of the solenoid valve 12. Fig.13 As shown, in the low beam mode, the light baffle 10 "lies down" and can rotate around the central optical axis of the lens 9 under the drive of the motor 2, so that the cut-off line of the low beam is always parallel to the ground. In the high beam mode, the light baffle 10 "stands up" under the action of the solenoid valve 12, and the movement trajectory is as shown in FIG. Fig.13 As shown by the arrows, the specific high and low beam light types are as follows Fig. 9 As shown, there is a light pattern above the cut-off line, especially in the middle part where there is a higher brightness high beam. The principle of the solenoid valve 12 is: when the solenoid valve is connected to current, a magnetic field will be generated, and the magnetic field will cause the valve core to move, thereby changing the degree of opening of the valve, and then controlling the flow of gas or liquid. Specifically, when the electromagnet is energized, the current passes through the coil to generate a magnetic field. This magnetic field makes the iron core a strong magnet and forms a magnetic field around the valve core. The magnetic field acts on the valve core. If the valve core is made of iron, it will be attracted by the magnetic force and move in the direction of the magnet; if the valve core is made of a material with weaker magnetism, such as aluminum alloy, it will be pushed open by the magnetic field. The movement of the valve core will change the opening of the valve, thereby controlling the flow of gas or liquid. If the current of the electromagnet is cut off and the magnetic field disappears, the valve core will return to its original position and close the valve. The valve here is Fig.12 The light-type baffle 10 is shown in the figure, and only a conventional solenoid valve 12 is shown in the figure. The specific structure of the solenoid valve 12 belongs to the prior art and will not be described in this embodiment.

[0043] Finally, it should be noted that the above implementation modes are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned implementation modes, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned implementation modes, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation modes of the present invention.
