Description

Technical Field

[0001] This invention relates to the field of automotive lighting technology, and more specifically, to an intelligent adjustment module for the headlight angle of an electric vehicle. Background Technology

[0002] With the continuous development of automotive lighting technology, adaptive headlight systems have become an important means of improving nighttime driving safety. Currently, the headlight angle adjustment devices of electric vehicles mainly use two independent drive units to control the horizontal steering and vertical automatic leveling functions respectively. However, this architecture of two independent systems has many shortcomings: on the one hand, the horizontal and vertical adjustments are independent of each other and lack linkage. When the vehicle accelerates or decelerates while turning, the two systems respond independently, making it difficult to achieve coordinated adjustment in the horizontal and vertical directions, resulting in unsatisfactory lighting effects. On the other hand, the transmission paths of existing adjustment mechanisms are generally long, with a large number of parts, large cumulative assembly tolerances, and elastic deformation and fit gaps in the transmission links, leading to response lag and reduced adjustment accuracy. In addition, the motion conversion mechanism of the transmission components in existing devices is relatively complex. In the process of converting rotary motion into linear motion, there are often problems of motion interference or low conversion efficiency. The overall module size is large and difficult to adapt to the limited space layout of the front compartment of an electric vehicle. Therefore, it is necessary to provide an intelligent headlight angle adjustment module for electric vehicles to solve the problems mentioned in the background technology. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides the following technical solution: an intelligent adjustment module for the headlight angle of an electric vehicle, comprising: A fixed base is fixedly installed on the front crossbeam of an electric vehicle. The lamp body is rotatably connected to the front end of the fixed base; An angle adjustment device is rotatably mounted at the front end of the fixed base and is fixedly connected to the side of the lamp body; The control and adjustment device is coaxially mounted with the fixed base and rotatably mounted on the fixed base, located at the center of the angle adjustment device; The transmission components are symmetrically distributed in two sets, connecting the angle adjustment device and the control adjustment device.

[0004] Furthermore, preferably, the fixing base includes: Mounting plate, fixedly installed on the front crossbeam of the electric vehicle; A control circular surface is fixed to the front end of the mounting plate, and a drive mechanism is provided inside the control circular surface; The ball socket is fixed at the center of the control circle.

[0005] Furthermore, as a preferred embodiment, a ball head is fixed to the rear end of the lamp body, and a connecting ring is fixed to the side. The ball head is embedded in a ball socket to form a universal joint. The connecting ring is fixedly connected to the angle adjustment device.

[0006] Furthermore, preferably, the angle adjustment device includes: Rotate the ring body, which is rotatably positioned at the front end of the fixed base; The inner track is adjusted, with two arc-shaped tracks distributed vertically and horizontally, both ends fixed to the rotating ring, and the center corresponding to the center of the ball socket. The positioning outer track corresponds to the adjusting inner track and is fixed on the outside of the adjusting inner track, with its inner wall fitting against the outer ring of the connecting ring; The movable adjustment components are provided in two symmetrically distributed sets, which are movably set on the inner adjustment track and fixedly connected to the side of the connecting ring; Two adjusting shafts are symmetrically distributed and are respectively connected to the ends of two sets of movable adjusting components, and the adjusting shafts are slidably connected to the transmission components.

[0007] Furthermore, preferably, the movement adjustment component includes: The center roller is set in the middle of the inner track for adjustment; Two positioning links are symmetrically distributed on both sides of the central roller, and the central roller is rotatably connected to the two positioning links. The end of the positioning link is fixedly connected to the side of the connecting ring, and the other end is fixedly connected to the adjusting shaft. The side rollers are set in correspondence with the positioning link, and are rolled on the inner track of the adjustment, and are rotatably connected to the end of the positioning link away from the center roller.

[0008] Furthermore, preferably, the control and adjustment device includes: Rotate the ring seat, which is rotatably mounted on the control circular surface; Two fixed tracks are symmetrically distributed and fixed to the front end of the rotating ring seat; An adjusting ring is rotatably mounted on a rotating ring seat, and the outer ring of the adjusting ring is provided with a toothed ring. Two curved tracks are symmetrically distributed, passing through the adjustment ring and corresponding to the fixed track; Adjust the slider; the bottom slider is set on the fixed track, and the top slider is set inside the arc. The connector corresponds to the fixed track and connects the adjusting slider and the transmission assembly.

[0009] Furthermore, preferably, the control and adjustment device further includes: The transmission gear meshes with the gear ring on the outer ring of the adjusting ring; The drive shaft connects the transmission gears and the control circular surface.

[0010] Furthermore, preferably, the transmission assembly includes: Connecting post, fixed to the outside of the connector; Two push rods are symmetrically distributed and fixed at both ends of the connecting column. The other end of the push rod is provided with a limiting groove that connects to the adjusting shaft. The connection between the push rod and the adjusting shaft is close to both ends of the adjusting shaft.

[0011] Compared with the prior art, the beneficial effects of the present invention are: In this invention, by rotating the ring body and adjusting the inner track, the same set of moving adjustment components can switch the execution direction between horizontal and vertical states, so that horizontal and vertical adjustment can share the same set of execution mechanisms without interfering with each other. By adjusting the inner track's arc center to correspond with the ball socket center and positioning the outer track's inner wall to fit snugly against the connecting ring's outer ring, the distance between the driving point and the rotation center remains constant when the lamp body deflects around the ball head's center of rotation. This ensures a strict linear correspondence between the deflection angle and the track's sliding arc length, significantly improving adjustment accuracy. The three-point support configuration, in which the central roller and the two side rollers of the movable adjustment component are triangularly distributed and all rolling on the inner track of the adjustment, ensures that the movable adjustment component is subjected to balanced force and moves smoothly under vehicle bumpy and vibrating conditions, and will not overturn or derail. By adjusting the combined constraint setting of the arc track on the ring and the adjusting slider on the fixed track, the continuous rotational motion of the drive shaft is precisely converted into the radial linear motion of the adjusting slider. Combined with the differential push-pull drive on both sides, the two sets of transmission components move synchronously in opposite directions and the lamp body deflection process is not subject to additional torsional torque. By using a floating connection where the end of the push rod has a sliding fit with the adjusting shaft and the length of the limiting groove is aligned with the axis of the push rod, the positional deviation caused by the adjusting shaft moving along the circular track with the moving adjusting component is automatically compensated by the axial sliding within the limiting groove, thus achieving interference-free conversion between circular motion and linear transmission.

[0013] Please see Figures 1-6 In this embodiment of the invention, an intelligent adjustment module for the headlight angle of an electric vehicle includes: Fixed base 1 is fixedly installed on the front crossbeam of the electric vehicle; The lamp body 2 is rotatably connected to the front end of the fixed base 1; Angle adjustment device 3 is rotatably mounted at the front end of the fixed base 1 and fixedly connected to the side of the lamp body 2; The control and adjustment device 4 is coaxially arranged with the fixed base 1, rotatably mounted on the fixed base 1, and located at the center of the angle adjustment device 3; The transmission assembly 5 is provided in two symmetrically distributed sets, connecting the angle adjustment device 3 and the control adjustment device 4.

[0014] In this embodiment, the fixed base 1 includes: Mounting plate 11 is fixedly installed on the front crossbeam of the electric vehicle; A control circular surface 12 is fixed to the front end of the mounting plate 11, and a drive mechanism is provided inside the control circular surface 12; The ball socket 13 is fixed at the center of the control circular surface 12.

[0015] In other words, the fixed base 1, as an absolutely stationary reference system, maintains a fixed position throughout the entire working process. The internal drive mechanism of its control circular surface 12 drives the angle adjustment device 3 to adjust the direction and controls the adjustment device 4 to adjust the angle according to the system instructions, thereby realizing the power output of the two independent drive circuits. The ball socket 13 provides a fulcrum for the universal rotation of the lamp body 2.

[0016] In this embodiment, a ball head 21 is fixed to the rear end of the lamp body 2, and a connecting ring 22 is fixed to the side. The ball head 21 is embedded in the ball socket 13 to form a universal joint. The connecting ring 22 is fixedly connected to the angle adjustment device 3.

[0017] In other words, the ball head 21 constrains the spatial position of the front end of the lamp body 2. The ball head 21 can only rotate and cannot translate within the ball socket 13. Therefore, the front end of the lamp body 2 is fixed. When the connecting ring 22 is driven by the angle adjustment device 3, it causes the rear end of the lamp body 2 to deflect. Since the front end is constrained by the ball head 21, the lamp body 2 swings in all directions around the center of the ball head 21. The control adjustment device 4 drives the transmission component 5 to move, and then drives the lamp body 2 to rotate through the angle adjustment device 3 and the connecting ring 22, thereby causing the lamp body 2 to undergo a corresponding angle change.

[0018] In this embodiment, the angle adjustment device 3 includes: Rotate the ring 31, which is rotatably positioned at the front end of the fixed base 1; The inner track 32 is adjusted, with two parallel tracks arranged in an arc shape, one above the other, and both ends fixed to the rotating ring 31. The center of the track corresponds to the center of the ball socket 13. The positioning outer track 33 corresponds to the adjusting inner track 32, is fixed on the outside of the adjusting inner track 32, and its inner wall fits against the outer ring of the connecting ring 22; The movable adjustment component 34 is provided in two symmetrically distributed sets, which are movably set on the inner adjustment track 32 and fixedly connected to the side of the connecting ring 22. Two adjusting shafts 35 are symmetrically distributed and are respectively connected to the corresponding ends of two sets of movable adjusting components 34, and the adjusting shafts 35 are slidably connected to the transmission component 5.

[0019] In other words, in the horizontal adjustment mode, when the vehicle is turning, the drive mechanism inside the control circle 12 drives the rotating ring 31 to rotate to a horizontal state (i.e., the two inner adjustment tracks 32 are located directly above and below the lamp body 2, respectively, and their arc extends horizontally). Then, the position of the rotating ring 31 is locked. At this time, when the vehicle turns left, the system receives the steering wheel angle signal, calculates the target horizontal deflection angle, drives the control adjustment device 4 to operate, and then pushes the right transmission component 5 and pulls the corresponding adjustment shaft 35 to move to the left through the left transmission component 5. The corresponding ends of the two sets of moving adjustment components 34 move synchronously, causing the two sets of moving adjustment components 34 to slide to the left along the inner adjustment track 32. During this process, the two adjustment shafts 35 jointly constrain the two sets of moving adjustment components 34. The synchronous movement of the lamp body 2 ensures that no additional pitch or torsion occurs when the lamp body 2 deflects horizontally, thus causing the headlight beam direction to deflect to the left and illuminate the inside of the curve. Conversely, when the vehicle turns right, the system receives the steering wheel angle signal, calculates the target horizontal deflection angle, drives the control adjustment device 4 to operate, and then pulls the corresponding adjustment shaft 35 to the right through the right transmission component 5 and pushes the left transmission component 5. The corresponding ends of the two sets of moving adjustment components 34 move synchronously, causing the two sets of moving adjustment components 34 to slide to the right along the inner adjustment track 32. During this process, the two adjustment shafts 35 jointly constrain the synchronous movement of the two sets of moving adjustment components 34, ensuring that no additional pitch or torsion occurs when the lamp body 2 deflects horizontally, thus causing the headlight beam direction to deflect to the right and illuminate the inside of the curve.

[0020] In a preferred embodiment, in vertical adjustment mode, i.e., rapid acceleration or deceleration, the drive mechanism inside the control circular surface 12 drives the rotating ring 31 to rotate to a vertical state (i.e., the two inner adjustment tracks 32 are located directly to the left and right of the lamp body 2, respectively, and their arc-shaped direction extends along the vertical direction). Then, the position of the rotating ring 31 is locked. When the vehicle accelerates rapidly, the front of the vehicle tilts up. After receiving the direction signal, the system calculates the target vertical deflection angle and drives the control adjustment device 4 to operate. This is then pushed by the upper transmission component 5 and the lower transmission component. Component 5 pulls the corresponding adjustment shaft 35 downward, and the two sets of moving adjustment components 34 slide downward along the inner adjustment track 32 as a whole, causing the connecting ring 22 and the lamp body 2 to deflect downward in the vertical direction. The ball head 21 assists in rotating in the ball socket 13 to achieve vertical leveling, thereby shifting the headlight illumination direction downward to offset the upward shift in illumination distance caused by the head of the vehicle tilting upward, and keeping the low beam illumination distance constant. Conversely, when the vehicle decelerates (brakes) suddenly, the head of the vehicle sinks, the lamp body 2 deflects upward, and the headlight illumination direction shifts upward to offset the shortening of illumination distance caused by the head of the vehicle sinking.

[0021] In a preferred embodiment, in the cooperative motion mode, such as when accelerating while turning, the system integrates the steering wheel angle signal and the pitch angle signal to calculate a comprehensive target angle, controls the circular surface 12 to drive the rotating ring 31 to rotate, so that the inner adjustment track 32 and the outer positioning track 33 are switched to a horizontal state, and the horizontal angle adjustment is completed by controlling the adjustment device 4. Then, the rotating ring 31 is controlled to rotate by controlling the circular surface 12, which drives the deflected lamp body 2 to rotate, thus completing the secondary pitch angle adjustment.

[0022] In this embodiment, the movable adjustment component 34 includes: The center roller 341 is rotatably positioned in the middle of the inner adjusting track 32; Two positioning links 342 are symmetrically distributed on both sides of the central roller 341. The central roller 341 is rotatably connected to the connection of the two positioning links 342. The end of the positioning link 342 is fixedly connected to the side of the connecting ring 22, and the other end is fixedly connected to the adjusting shaft 35. The side roller 343 is correspondingly set on the positioning link 342, and is rolled on the inner track 32. It is rotatably connected to the end of the positioning link 342 away from the center roller 341.

[0023] In other words, taking a vehicle turning left as an example, the right transmission component 5 pushes the adjustment shaft 35 to move to the left, while the left transmission component 5 pulls the corresponding adjustment shaft 35 to move to the left. The two sets of transmission components 5 drive the corresponding side rollers 343 to roll to the left on the inner track 32 through the adjustment shaft 35, which in turn drives the center roller 341 to roll to the left along the inner track 32. Its movement trajectory is an arc (with the center of the ball socket 13 as the center). The two positioning links 342 move synchronously with the center roller 341. Since the connecting end of the positioning link 342 is fixedly connected to the side of the connecting ring 22, the movement of the positioning link 342 directly drives the connecting ring 22 to deflect to the left. The connecting ring 22 is fixed to the side of the lamp body 2. Therefore, the lamp body 2 deflects to the left with the center of the ball head 21 as the rotation center, realizing the horizontal following steering.

[0024] It is important to note that the angle of the positioning link 342 needs to be selected with a suitable initial angle. If the distance between the center roller 341 and the side roller 343 is too far, the moving adjustment component 34 will get stuck when sliding. If the distance is too close, the push rod 52 will interfere with the connecting ring 22 on the lamp body 2. By reasonably designing the length and initial included angle of the positioning link 342 (preferably 120°-150°), the moving adjustment component 34 can roll smoothly on the inner adjustment track 32, and the movement range of each component will not interfere with each other.

[0025] In this embodiment, the control and adjustment device 4 includes: Rotate the ring seat 41, which is rotatably mounted on the control circular surface 12; Fixed track 42, two of which are symmetrically distributed, fixed the front end of the rotating ring seat 41; Adjusting ring 43 is rotatably mounted on rotating ring seat 41, and the outer ring of adjusting ring 43 is provided with a toothed ring; Two arc tracks 44 are symmetrically distributed, passing through the adjusting ring 43 and corresponding to the fixed track 42; Adjust slider 45, with its bottom sliding set on fixed track 42 and its top sliding set inside arc track 44; Connector 46, corresponding to fixed track 42, connects adjusting slider 45 and transmission assembly 5.

[0026] In this embodiment, the control and adjustment device 4 further includes: The transmission gear 47 meshes with the gear ring on the outer ring of the adjusting ring 43; The drive shaft 48 connects the transmission gear 47 and the control circular surface 12.

[0027] In other words, the core function of the control and adjustment device 4 is to convert the rotational motion of the drive shaft 48 into the radial linear motion of the adjustment slider 45, and output it to the transmission assembly 5 through the connector 46. Its operation is divided into the following three states: State 1: deflection in the horizontal direction, the left adjustment slider 45 is pushed out and the right adjustment slider 45 is retracted (achieving leftward rotation in the horizontal direction). The drive mechanism inside the control circular surface 12 drives the transmission gear 47 to rotate through the drive shaft 48. The transmission gear 47 drives the adjustment ring 43 to rotate. Since the arc track 44 is an arc groove, when the adjustment ring 43 rotates (the direction of rotation is determined by the direction of the arc track 44), the arc track 44 on the left side exerts an outward (leftward) pushing force on the adjustment slider 45 located therein, causing the left adjustment slider 45 to slide to the left (radially outward) along the fixed track 42; at the same time, the arc track 44 on the right side exerts an inward pulling force on the adjustment slider 45 located therein, causing the right adjustment slider 45 to slide to the left (radially inward) along the fixed track 42 on the right side. The movement of the two adjustment sliders 45 is transmitted through the connector 46. 6 is transmitted to two sets of transmission components 5 respectively, realizing differential drive of "one push and one pull", which together pushes the moving adjustment component 34 to drive the lamp body 2 to rotate to the left; State 2: deflection in the vertical direction, the lower adjustment slider 45 is pushed out and the upper adjustment slider 45 is retracted (realizing vertical tilting and leveling), the drive mechanism inside the control circle 12 drives the transmission gear 47 to rotate through the drive shaft 48, the transmission gear 47 drives the adjustment ring 43 to rotate, at this time the direction of action of the arc track 44 on the adjustment slider 45 changes from horizontal to vertical, the upper adjustment slider 45 moves down along the fixed track 42, the lower adjustment slider 45 moves down along the fixed track 42, and the transmission component 5 is driven by the connector 46 to realize push and pull, which together pushes the moving adjustment component 34 to drive the lamp body 2 to rotate downward; State 3: straight and flat road surface, zero position, the drive shaft 48 is not driven or remains stationary, the adjustment ring 43 is at the initial angle, both adjustment sliders 45 are located in the middle position of the fixed track 42, the two transmission components 5 do not apply driving force to the angle adjustment device 3, and the lamp body 2 remains positive and centered.

[0028] In this embodiment, the transmission assembly 5 includes: The connecting post 51 is fixed to the outside of the connector 46; Two push rods 52 are symmetrically distributed and fixed at both ends of the connecting column 51. The other end of the push rod 52 is provided with a limiting groove 53 that is connected to the adjusting shaft 35. The connection between the push rod 52 and the adjusting shaft 35 is close to both ends of the adjusting shaft 35.

[0029] In other words, the length direction of the limiting groove 53 is consistent with the axial direction of the push rod 52. The adjusting shaft 35 can slide freely in the limiting groove 53 along the axial direction of the push rod 52, but cannot leave the limiting groove 53. When the push rod 52 pushes the moving adjusting component 34 to slide on the adjusting inner track 32 through the adjusting shaft 35, the limiting groove 53 allows the adjusting shaft 35 to have a certain amount of floating in the axial direction of the push rod 52. The limiting groove 53 is used to adapt to the height deviation generated when the adjusting shaft 35 follows the moving adjusting component 34 in a circular motion.

[0030] In specific implementation, initially in the straight-ahead state, the internal drive mechanism of the control circular surface 12 of the fixed base 1 locks the rotating ring 31 in a preset posture, the drive shaft 48 remains stationary so that the adjusting ring 43 is at the initial angle, the adjusting slider 45 is located in the middle of the fixed track 42, and the lamp body 2 remains centered in the positive direction; when the vehicle turns, the control circular surface 12 first drives the rotating ring 31 to rotate to a horizontal state and locks it, so that the two arc-shaped adjusting inner tracks 32 are located directly above and directly below the lamp body 2, respectively. Then, the drive shaft 48 drives the adjusting ring 43 to rotate through the transmission gear 47, and the arc track 44 pushes the adjusting slider 45 to slide radially along the fixed track 42, so that the two adjusting sliders 45 on both sides move in a differential push-pull manner. The movement is transmitted through the connector 46 and the connecting column 51 to the push rod 52. The limiting groove 53 at the end of the push rod 52 drives the adjusting shaft 35 to move. The two sets of adjusting shafts 35 drive the two side moving adjusting components 34 to slide synchronously along the inner adjusting track 32. The center roller 341 and the side roller 343 in the moving adjusting component 34 roll along the arc track. The positioning connecting rod 342 drives the connecting ring 22 to make the lamp body 2 deflect horizontally with the center of the ball head 21 and the ball socket 13 as the rotation center, realizing the curve-following steering. When the vehicle accelerates or decelerates rapidly, the control circular surface 12 first drives the rotating ring body 31 to rotate to the vertical state and lock it, so that the two inner adjusting tracks 32 are located directly to the left and right of the lamp body 2, respectively. On the right, similarly, the drive shaft 48 drives the adjusting ring 43 to rotate via the transmission gear 47. The arc track 44 pushes the adjusting slider 45 to slide radially up and down along the fixed track 42. Through the connecting piece 46, connecting column 51 and push rod 52, the adjusting shaft 35 is driven to move up and down, causing the moving adjusting assembly 34 to slide up and down along the inner adjusting track 32 as a whole. The center roller 341 and the side roller 343 roll along the vertical arc track. The positioning link 342 drives the lamp body 2 to rotate vertically around the center of the ball head 21 and the ball socket 13 via the connecting ring 22, thus achieving pitch attitude compensation. In the cooperative working condition, such as when turning and accelerating at the same time, the system calculates the target angle by integrating the steering wheel angle signal and the pitch angle signal. First, the control circular surface 12 drives the rotating ring 31 to switch to a horizontal state to complete the horizontal deflection. Then, the control circular surface 12 drives the rotating ring 31 to rotate, causing the already deflected lamp body 2 to switch with the track to complete the secondary pitch angle adjustment. During the entire movement, the adjusting shaft 35 slides freely along the axial direction in the limiting groove 53 of the push rod 52 to adapt to the position deviation generated when the moving adjusting component 34 moves along the arc track. All components work together to complete the angle adjustment. When the initial straight state is restored, the drive shaft 48 rotates in the opposite direction to reset the adjusting ring 43, the adjusting slider 45 returns to the middle position of the fixed track 42, the moving adjusting component 34 returns to the initial position along the inner adjusting track 32, and the lamp body 2 returns to the positive centering state.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
