Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a vehicle headlight with an adjustable lamp bead emission angle. Background Technology

[0002] As an automotive component, headlights are a key structure for ensuring safe driving, such as providing illumination and lane change warnings. Therefore, ensuring the performance of headlights has always been a focus of research in the industry.

[0003] Currently, existing vehicle lights on the market are divided into two types: fixed and movable. Fixed vehicle lights have a fixed internal structure and cannot adjust the angle of the emitted light. When used for general illumination, the lights cannot illuminate at specific angles. However, for some existing usage scenarios, such as off-road driving or other everyday situations where lighting is needed at night to set up tents or cook over a fire in front of or behind the vehicle, while the lights need to be restored to standard settings during normal driving; or in special scenarios such as nighttime military operations where it is necessary to prevent the light from spreading over a wide area and to ensure following safety, the visible range of the lights needs to be controlled to the driver's cab area or the driver's seat area of ​​the following vehicle to avoid attracting attention, while in normal use scenarios, the lights can be restored to the same light distribution effect as ordinary vehicle lights. Fixed vehicle lights cannot meet these requirements. Although movable car lights can adjust the angle of emitted light through structural movement and adapt to the vehicle's driving environment, such as the anti-glare car light disclosed in patent CN218442052U, which has a lamp cover set above a mounting plate and a lower housing set below the mounting plate, with an adjustment mechanism at the top of the mounting plate, the lamp beads are set on the angle adjustment mechanism via lamp holders, and the connecting rods of the angle adjustment mechanism are symmetrically arranged on the mounting plate. A rotating shaft is rotatably set between the two connecting rods, and the lamp holder is sleeved on the rotating shaft. There is an installation space between the bottom of the lamp holder and the top of the mounting plate. The driven gear is sleeved on the rotating shaft on one side of the lamp holder, and the drive motor is set on the mounting plate below the lamp holder. The drive gear is set on the output end of the drive motor, and the drive gear meshes with the driven gear. The drive motor drives the drive gear to rotate, which in turn drives the rotating shaft where the driven gear is located to rotate the lamp holder, thereby adjusting the angle of the lamp beads on the lamp holder and meeting the adjustment requirements of the illumination angle. Although the above structure can meet the adjustment of the light-emitting angle of the LED, the lamp holder needs to be connected to the drive motor, which means the drive motor needs to be installed inside the headlight. However, existing drive motors on the market are difficult to miniaturize and still require a large space. Therefore, this structure is usually only for headlights with a single LED or multiple LEDs in a headlight installed on the same lamp holder. It can achieve overall adjustment of the light-emitting angle of a single LED or multiple LEDs at the same time through the lamp holder, but it cannot achieve differentiated adjustment of the light-emitting angle of multiple LEDs. This results in high limitation of adjustment, limited adjustment effect, and relatively poor adaptability, which is not conducive to its widespread use. Summary of the Invention

[0004] To address the aforementioned problems in existing technologies, the aim is to provide a vehicle headlight with adjustable lamp bead beam angles. Each lamp bead has an adjustment seat, and the beam angle of the corresponding lamp bead can be individually adjusted through the action of each adjustment seat. This allows for differentiated adjustment of the beam angles of multiple lamp beads, with fewer adjustment limitations, higher adjustability, and the ability to meet more adjustment schemes. It also offers better adaptability, better adjustment effect, and is conducive to widespread use.

[0005] The specific technical solution is as follows: A vehicle headlight with adjustable LED beam angle includes a housing, a circuit board, several reflectors, and several LEDs. The circuit board, reflectors, and LEDs are all housed within the housing. Each LED is electrically connected to the circuit board, and each LED corresponds to a reflector. The headlight also includes several adjustment seats, each corresponding to one LED. Each adjustment seat includes an adjustment bracket, a base, a rotating component, and a deflection drive component. The adjustment frame includes a first rod and a second rod, which are perpendicular to each other. LED beads are installed at the intersection of the first rod and the second rod of the adjustment frame. The base frame is located below the adjustment frame. The base frame includes a first support part and a second support part, which cooperate with the first rod and the second rod respectively to realize the driving of the first rod and the second rod. The rotating component is installed between the adjusting frame and the base frame. The rotating component is located at the intersection of the first rod and the second rod and is located below the lamp bead. A deflection drive is provided between the first rod and the first support, as well as between the second rod and the second support.

[0006] The aforementioned vehicle headlight with adjustable LED light emission angle includes a deflection drive component comprising a slant rail, a slider, and a telescopic component. The bottom of both the first and second rods is equipped with slant rails arranged along their length, with one end of the slant rails tilting downwards. A slider is slidably disposed on both the first and second support parts and is slidably connected to the corresponding slant rails. Telescopic components are disposed on both the first and second support parts and are poweredly connected to the corresponding sliders.

[0007] In the aforementioned vehicle light with adjustable lamp bead luminous angle, a pivot is provided between the inclined rail and the corresponding first or second rod, and the axis of the pivot is the length direction of the corresponding first or second rod.

[0008] In the aforementioned vehicle headlight with adjustable LED light emission angle, a groove is provided on the slider. The groove has a "T"-shaped cross-section, and the cross-section of the lower edge of the inclined rail is consistent with the cross-section of the groove.

[0009] In the aforementioned vehicle headlight with adjustable LED light emission angle, a sliding cavity is provided in both the first support part and the second support part. The end of the slider that is away from the inclined rail is slidably disposed in the sliding cavity. The telescopic component is installed in the sliding cavity and one end is connected to the slider, while the other end is connected to the cavity wall of the sliding cavity.

[0010] The aforementioned vehicle light with adjustable lamp bead emitting angle further includes a pre-tension spring, which is disposed within a sliding cavity and on the side of the slider away from the telescopic member.

[0011] In the aforementioned vehicle headlight with adjustable lamp bead luminous angle, the deflection drive component includes a connecting part and a telescopic part. The connecting part is installed at the end of the telescopic part, and the end of the connecting part away from the telescopic part is connected to a first rod or a second rod. The other end of the telescopic part is connected to a corresponding first support or a second support.

[0012] In the aforementioned vehicle headlight with adjustable lamp bead luminous angle, the connecting part is a universal joint, the telescopic part is hinged to the first support part or the second support part, and the sway plane is the plane containing the length direction of the first rod or the second rod.

[0013] The aforementioned type of vehicle headlight with adjustable LED light emission angle includes an adjustment bracket made of metal.

[0014] The aforementioned vehicle light with adjustable lamp bead luminous angle includes a rotating component that is a universal joint, comprising a ball and a cover. A ball cup is provided on the base frame, and a cover is provided on the base frame at the opening of the ball cup. The ball is disposed inside the ball cup, with one end protruding from the cover to the outside of the base frame. The end of the ball protruding to the outside of the base frame is fixedly connected to the connection between the first rod and the second rod of the adjustment frame.

[0015] The positive effects of the above technical solution are: The aforementioned vehicle headlight with adjustable LED bead beam angle features an adjustment seat located within the housing for each LED bead. Each adjustment seat includes an adjustment frame with an L-shaped first and second rod, a base corresponding to the first and second rods, a rotating component, and a deflection drive component positioned between the adjustment seat and the base. When an LED bead is mounted on the adjustment seat, the deflection drive component drives the first and / or second rods of the adjustment seat to deflect, thus adjusting the LED bead beam angle. The rotating component adapts to the angle deflection requirements of the adjustment frame on the base, maintaining stability and reliability after the adjustment frame is connected to the base, ensuring the headlight's performance. Furthermore, it allows for individual adjustment of each LED bead, meeting the differentiated adjustment needs of multiple LED bead beam angles, reducing adjustment limitations, accommodating more adjustment schemes, improving adaptability, ensuring adjustment effectiveness, and facilitating widespread use.

Detailed Implementation

[0018] To make the technical means, creative features, objectives, and effects of this invention easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 3 The technical solutions provided by this invention are described in detail, but the following content is not intended to limit this invention.

[0019] Figure 1 This is a structural diagram of an embodiment of a vehicle lamp with an adjustable lamp bead emission angle according to the present invention; Figure 2 This is a schematic diagram of an adjustment base for a vehicle headlight with an adjustable lamp bead emission angle according to the present invention. Figure 1 and Figure 2 As shown, the vehicle headlight with adjustable LED beam angle provided in this embodiment includes: a housing 1, a circuit board, several reflectors, and several LEDs 2. The circuit board, reflectors, and LEDs 2 are all housed within the housing 1, providing both a mounting platform and external protection for the circuit board, reflectors, and LEDs 2. It is worth noting that each LED 2 is electrically connected to the circuit board, and each LED 2 corresponds to a reflector, allowing the LED's light emission state to be controlled by the circuit board and diffused through the reflectors, meeting normal usage requirements. Furthermore, since the structure of controlling the light emission through a circuit board and emitting light through reflectors in existing vehicle headlights is already very mature and widely used, the specific structure of the circuit board, reflectors, and LEDs 2 will not be described in detail here.

[0020] Figure 3 This is a schematic diagram of an adjustment bracket for a vehicle headlight with an adjustable lamp bead emission angle according to the present invention. Figure 2 and Figure 3As shown, each LED bead 2 also corresponds to an adjustment seat 3, which allows for the adjustment of the light emission angle of the corresponding LED bead 2, thus providing conditions for subsequent differentiated adjustment of the light emission angle of multiple LED beads 2. Furthermore, each adjustment seat 3 includes an adjustment frame 31, a base frame 32, a rotating component 33, and a deflection drive component 34. The adjustment frame 31 includes a first rod 311 and a second rod 312, which are perpendicularly intersecting, providing conditions for subsequent tilting in two directions within the plane, thereby achieving left-right and up-down adjustment of the light emission direction of the LED bead 2. When the LED bead 2 is installed at the intersection of the first rod 311 and the second rod 312 of the adjustment frame 31, the LED bead 2 can be tilted when either the first rod 311 or the second rod 312 is tilted, thus achieving adjustment of the light emission direction of the LED bead 2. Additionally, the base frame 32 is positioned below the adjustment frame 31, providing conditions for subsequent adjustment of the tilt angle of the adjustment frame 31 by cooperating with the base frame 32. Furthermore, the base frame 32 includes a first support portion and a second support portion 321, which respectively cooperate with the first rod 311 and the second rod 312 to drive the first rod 311 and the second rod 312. This allows the first rod 311 to be driven by the first support portion when it moves, while the second rod 312 can be driven by the second support portion 321 when it moves, thus satisfying the requirement for independent driving of the first rod 311 and the second rod 312. At the same time, a rotating member 33 is installed between the adjusting frame 31 and the base frame 32. The rotating member 33 is located at the intersection of the first rod 311 and the second rod 312 and below the LED bead 2. That is, the rotating member 33 fulfills the installation requirement of supporting the adjusting frame 31 on the base frame 32, and also enables the relative rotation of the adjusting frame 31 on the base frame 32, providing conditions for the subsequent tilting of the LED bead 2 on the adjusting frame 31. In addition, a deflection drive 34 is provided between the first rod 311 and the first support portion, as well as between the second rod 312 and the second support portion 321, to provide driving force for the tilting of the first rod 311 and the second rod 312.

[0021] Specifically, the deflection drive component 34 of the adjustment seat 3 includes a sloping rail 341, a slider 342, and a telescopic component 343. At this time, the bottom of the first rod 311 and the second rod 312 are both equipped with sloping rails 341 arranged along their length direction, and one end of the sloping rail 341 is inclined downward. A slider 342 is slidably arranged on the first support part and the second support part 321 and is slidably connected to the corresponding sloping rail 341. That is, when the slider 342 moves horizontally, the position of the slider 342 on the sloping rail 341 can be changed. Since the sloping rail 341 is an inclined structure, when the slider 342 moves horizontally, the height of the sloping rail 341 can be adjusted, thereby achieving the tilting of the first rod 311 or the second rod 312, and realizing the adjustment of the light emission angle of the lamp bead 2 installed on the adjustment seat. In addition, both the first support and the second support 321 are provided with telescopic members 343, and the telescopic members 343 are poweredly connected to the corresponding slider 342, that is, the telescopic members 343 provide driving force for the movement of the slider 342 relative to the inclined rail 341.

[0022] More specifically, a rotating shaft 344 is provided between the inclined rail 341 and the corresponding first rod 311 or second rod 312, and the axis of the rotating shaft 344 is the length direction of the corresponding first rod 311 or second rod 312. This allows the rotation direction of the rotating shaft 344 on the first rod 311 to adapt to the deflection of the second rod 312, and the rotation direction of the rotating shaft 344 on the second rod 312 to adapt to the deflection of the first rod 311. This effectively avoids the problem that the first rod 311 will be stuck by the inclined rail 341 on the second rod 312 when it deflects, or the second rod 312 will be stuck by the inclined rail 341 on the first rod 311 when it deflects, thus ensuring the smooth deflection of the adjusting frame 31.

[0023] More specifically, a groove is also provided on the slider 342. The groove has a "T"-shaped cross-section. At the same time, the cross-section of the lower edge of the inclined rail 341 is consistent with the cross-section of the groove. This ensures that when the slider 342 and the inclined rail 341 are engaged, the relative movement between the inclined rail 341 and the slider 342 is only in the length direction of the inclined rail 341. There is no relative rotation between the two, thus maintaining the stability of the arrangement direction of the inclined rail 341. This ensures that the slider 342 can reliably act on the inclined rail 341 to achieve the deflection of the adjustment frame 31, making the structural design more reasonable.

[0024] More specifically, a sliding cavity 3211 is provided in both the first support part and the second support part 321, and the end of the slider 342 facing away from the inclined rail 341 is slidably disposed in the sliding cavity 3211, realizing the installation of the slider 342 on the first support part and the second support part 321. In addition, the telescopic member 343 is installed in the sliding cavity 3211, with one end connected to the slider 342 and the other end connected to the cavity wall of the sliding cavity 3211, so that when the telescopic member 343 performs telescopic movement, it can drive the slider 342 to move in the sliding cavity 3211. This achieves both concealed installation of the telescopic member 343 and meets the usage requirements of driving the slider 342.

[0025] More specifically, a pre-tension spring 345 is also installed inside the sliding cavity 3211. In this case, the pre-tension spring 345 is positioned on the side of the slider 342 away from the telescopic member 343, meaning the telescopic member 343 and the pre-tension spring 345 are located on opposite sides of the slider 342. The pre-tension spring 345 constantly provides a clamping force to the telescopic member 343, ensuring that the telescopic member 343 is always under tension. This avoids the problem of unstable slider 342 position caused by a loose telescopic member 343, thus preventing fluctuations in the light emission angle of the LED bead 2 due to changes in slider 342 position caused by bumps in the vehicle. The structural design is more reasonable. Furthermore, when the telescopic member 343 retracts, the clamping spring assists in pushing the slider 342, preventing the telescopic member 343 from jamming during retraction and ensuring the rapid adjustment of the light emission angle of the LED bead 2. Preferably, the telescopic member 343 is an airbag. The expansion or contraction of the airbag's volume is achieved by inflating and deflating the airbag, thereby pushing the slider 342 to move. It is worth noting that since the airbag's expansion or contraction does not require any other structural components, its size can be made very small when using it as the telescopic component 343, about the size of a grain of rice, better meeting the needs of applications with limited installation space inside the headlight. Furthermore, the airbag only requires a single inlet for inflation or deflation, meaning that only a pipe needs to be connected to the air pump outside the headlight via the airbag's inlet. Inflation is achieved when the air pump is pumped in the forward direction, while deflation is achieved when the air pump is pumped out in the reverse direction, reducing manufacturing costs.

[0026] In addition, this embodiment also provides a deflection drive with another structure. In this case, the deflection drive 34 includes a connecting part and a telescopic part. The connecting part is installed at the end of the telescopic part, realizing the connection between the connecting part and the telescopic part. At the same time, the end of the connecting part away from the telescopic part is connected to the first rod 311 or the second rod 312, and the other end of the telescopic part is connected to the corresponding first support part or the second support part 321. That is, the relative angle between the first rod 311 and the first support part and the second rod 312 and the second support part 321 can be adjusted by the telescopic movement of the telescopic part. This can also realize the deflection of the adjustment frame 31 in two directions, satisfying the adjustment of the light emission angle of the lamp beads 2 installed on the adjustment frame 31. Preferably, the telescopic part is a cylinder. The air inlet and air outlet of the cylinder are respectively connected to the air pump outside the vehicle light through pipes. The air pump realizes active air intake and active exhaust, thereby realizing the active extension or active retraction of the cylinder, ensuring that the deflection drive 34 can move quickly and smoothly, and improving the effect of light emission angle adjustment.

[0027] More specifically, the connecting part of the aforementioned deflection drive component 34 is preferably a universal joint, that is, the telescopic part is connected to the first rod 311 or the second rod 312 through the universal joint, so that the connecting part can adapt to the deflection requirements of the first rod 311 and the second rod 312, avoiding the problem that the deflection of the first rod 311 is jammed at the connection between the second rod 312 and the deflection drive component 34, and the problem that the deflection of the second rod 312 is jammed at the connection between the first rod 311 and the deflection drive component 34. In addition, the telescopic part is hinged to the first support part or the second support part 321, and the deflection plane is the plane in the length direction of the first rod 311 or the second rod 312. This prevents the telescopic part from rotating in the plane in the width direction of the first rod 311 or the second rod 312, thereby ensuring the relative reliability of the installation position of the telescopic part and avoiding the jamming problem caused by relative torsion between the first rod 311, the second rod 312 and the corresponding telescopic part. The structural design is more reasonable.

[0028] More specifically, the adjustment bracket 31 of the adjustment seat 3 is made of metal, preferably aluminum, which can be used to assist in heat dissipation and improve the heat dissipation effect.

[0029] More specifically, the rotating component 33 of the adjusting seat 3 is a universal joint, including a ball 331 and a pressure cap 332. A ball cup is mounted on the base frame 32, and a pressure cap 332 is located on the base frame 32 at the opening of the ball cup. The pressure cap 332 forms a constricted structure in the ball cup, providing conditions for subsequently confining the ball 331 within the ball cup. Furthermore, the pressure cap 332 is screwed onto the base frame 32, facilitating its installation and removal, and providing conditions for subsequent maintenance and repair of the rotating component 33. Simultaneously, the ball 331 is located within the ball cup, with one end protruding from the pressure cap 332 to the outside of the base frame 32. The end of the ball 331 protruding from the base frame 32 is fixedly connected to the connection point of the first rod 311 and the second rod 312 of the adjusting frame 31, meeting the usage requirements for connecting the adjusting frame 31.

[0030] The vehicle headlight with adjustable lamp bead emission angle provided in this embodiment includes a housing 1, a circuit board, several reflectors, several lamp beads 2, and several adjustment seats 3. An adjustment seat 3 is provided at each lamp bead 2, and the first rod 311 and the second rod 312 of the adjustment frame 3 are arranged perpendicularly to each other. A base frame 32 is provided with a first support portion and a second support portion 321 corresponding to the first rod 311 and the second rod 312, respectively. Furthermore, between the first rod 311 and the first support portion, and between the second rod 312 and the second support portion 321... Each lamp bead 311 is equipped with a deflection drive 34. In addition, a rotating part 33 is provided between the connection between the first rod 311 and the second rod 312 and the base frame 32. When the deflection drive 34 is activated, it can push the first rod 311 and / or the second rod 312 to deflect, thereby adjusting the light emission angle of the lamp bead 2. Each lamp bead 2 has an independent adjustment seat 3 to meet individual adjustment needs, realize differentiated adjustment of the light emission angle of multiple lamp beads 2, make the adjustment more flexible, less restrictive, and more adaptable, thereby ensuring the adjustment effect and ensuring the market competitiveness of the product.
