Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting module technology, specifically to a vehicle steering auxiliary lighting module. Background Technology

[0002] Good nighttime lighting is crucial for the safety of electric bicycle riders. Currently, most electric bicycle headlights on the market are fixed installations, and their illumination range is generally sufficient for straight-line travel. However, when turning at night, because the headlights do not turn with the vehicle, the light still shines directly ahead, resulting in severely insufficient lighting on the inside of the curve, creating large blind spots. Riders cannot see road conditions within the curve in time, such as obstacles, potholes, or pedestrians, posing a significant safety hazard.

[0003] In addition, when electric bicycles turn, the body will naturally tilt or lean to the side, which will further cause the fixed-mounted headlight axis to deflect, causing the illumination range to deviate from the expected area and exacerbating the lack of visibility in the curve.

[0004] Therefore, there is an urgent need for a low-cost, high-reliability headlight compensation solution specifically designed for electric bicycles, which can enable the headlights to deflect synchronously when turning, directly illuminating the direction of travel and effectively expanding the lighting range on the inside of the curve to ensure riding safety. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a vehicle steering auxiliary lighting module, which can effectively expand the lighting range on the inside of the curve to ensure riding safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vehicle steering assist lighting module includes a module housing, a drive motor integrated within the module housing, a drive gear fixedly connected to the output end of the drive motor, a driven gear meshing with the drive gear, a bearing seat fixedly disposed at the bottom of the module housing, a main shaft rotatably mounted on the bearing seat, a secondary shaft horizontally connected to the main shaft, and a lamp support plate fixedly disposed at the front end of the secondary shaft.

[0008] The driven gear is coaxially fixed to the main shaft, the central axis of the secondary shaft is coplanar with and orthogonal to the central axis of the main shaft, and the front side of the lamp assembly support plate is used to fix and install the vehicle lamp assembly.

[0009] Furthermore, the secondary shaft includes a shaft fixedly connected to the main shaft and an inner shaft;

[0010] The end face of the shaft is provided with a through hole through the main shaft along the axial direction. The inner shaft is inserted into the through hole and rotates with the through hole. The lamp assembly support plate is fixedly connected to the outer end of the inner shaft.

[0011] One end of the inner shaft extends to the outside of the through hole and is fixedly connected to a shift fork, the shift fork having two symmetrically distributed fork arms;

[0012] Two vertical support rods are fixedly installed at the bottom of the module housing. Each vertical support rod has a horizontal stop bar fixed at its upper end. The two horizontal stop bars are symmetrically arranged on both sides of the shift fork.

[0013] When the main shaft rotates, the shift fork is limited by the transverse stop, which drives the inner shaft to rotate relative to the shaft.

[0014] Furthermore, two limiting plates are fixedly installed on the inner shaft, and the two limiting plates abut against the two end faces of the through hole respectively, in order to restrict the axial movement of the inner shaft.

[0015] Furthermore, the two forks of the shift fork are higher than the horizontal plane where the central axis of the inner shaft is located, and the two forks have a symmetrically converging inclined structure from bottom to top.

[0016] Furthermore, a return spring is provided between the lower middle part of the shift fork and the inner bottom surface of the module housing. When the shift fork is in the central equilibrium position, the return spring is in the minimum tension state in the vertical direction.

[0017] This utility model embodiment provides a vehicle steering assist lighting module. It has the following beneficial effects:

[0018] 1. The drive motor receives signals from the vehicle controller, drives the drive gear to rotate, and then meshes with the driven gear and the main shaft to rotate. This causes the sub-shaft and vehicle lights fixed on it to deflect horizontally around the main shaft axis, so that when the electric vehicle turns, the lights can illuminate the inside of the curve in advance, directly illuminating the driving trajectory. This fundamentally eliminates the blind spot caused by fixed lights, greatly improving riding safety when turning at night.

[0019] 2. A fork fixed to the inner shaft swings as the main shaft rotates. When the fork arm contacts the fixed lateral stop, the fork, under the limiting action, drives the inner shaft to rotate around its own axis within the through hole of the shaft. This roll rotation is transmitted to the lamp assembly support plate through the inner shaft, causing the headlight to generate an upward tilt angle. This effectively counteracts the downward shift of the illumination range caused by the side pressure of the electric bicycle when turning, allowing the beam to be maintained and raised, further optimizing the actual lighting effect in curves and ensuring clear visibility.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] See attached document Figure 1-4 This utility model provides a vehicle steering auxiliary lighting module, which mainly includes a module housing 1, a drive motor 2, a drive gear 3, a driven gear 4, a bearing seat 5, a main shaft 6, a countershaft 7, a lamp assembly support plate 8, a vertical support rod 9, a horizontal stop bar 10, and a return spring 11.

[0027] The module housing 1 serves as the supporting and protective structure for the entire module, forming an internal opening for connecting the lamp assembly and a relatively enclosed mounting space at the rear. The drive motor 2 is fixedly integrated into the inner wall of the module housing 1 using bolts or other means. A drive gear 3 is fixedly connected to the output shaft of the drive motor 2.

[0028] The bearing housing 5 is fixedly disposed at the inner bottom of the module housing 1. The main shaft 6 is rotatably mounted on the bearing housing 5 via bearings. The driven gear 4 is coaxially fixedly mounted on the main shaft 6 and meshes with the drive gear 3 to form a gear transmission pair. When the drive motor 2 is working, it can drive the main shaft 6 to rotate around its own axis through the transmission of the drive gear 3 and the driven gear 4.

[0029] The secondary shaft 7 is horizontally connected to the main shaft 6. Specifically, the secondary shaft 7 includes a shaft 701 and an inner shaft 702. One end of the shaft 701 is fixedly connected to the main shaft 6, and its central axis is coplanar and orthogonal to the central axis of the main shaft 6. A through hole 7011 is formed on the end face of the shaft 701 along its axial direction, and the through hole 7011 extends into the interior of the main shaft 6. The inner shaft 702 is inserted into the through hole 7011 and forms a rotational fit with the through hole 7011. To prevent the inner shaft 702 from moving axially, two limiting plates 704 are fixedly provided on the inner shaft 702, and the two limiting plates 704 are respectively tightly attached to and abut against the two end faces of the through hole 7011.

[0030] The lamp assembly support plate 8 is fixedly connected to the outer end of the inner shaft 702 (i.e. the end away from the main shaft 6) for fixing and installing the vehicle lamp assembly.

[0031] To achieve roll compensation during cornering, a shift fork 703 is fixedly connected to one end of the inner shaft 702, extending to the outside of the through hole 7011. This shift fork 703 has two symmetrically distributed fork arms. Two vertical support rods 9 are fixedly installed at the bottom inner part of the module housing 1, with a horizontal stop bar 10 fixedly mounted horizontally at the upper end of each vertical support rod 9. The two horizontal stop bars 10 are symmetrically arranged on both sides of the shift fork 703.

[0032] To further optimize the smoothness of the movement and the automatic reset function, the two forks of the shift fork 703 are designed to be higher than the horizontal plane where the central axis of the inner shaft 702 is located, and the two forks have a symmetrically converging inclined structure from bottom to top. A reset spring 11 is provided between the lower middle part of the shift fork 703 and the inner bottom surface of the module housing. When the vehicle is traveling straight and the shift fork 703 is not under the action of the lateral stop 10 and is in a centrally balanced position, the reset spring 11 is in a minimum tension state in the vertical direction.

[0033] Work process:

[0034] In this invention, when the vehicle turns, the lights will simultaneously provide steering illumination and roll illumination to the turning side.

[0035] Turning illumination: When the vehicle needs to turn, the vehicle controller sends a command to the drive motor 2. The drive motor 2 starts, and through the meshing of the drive gear 3 and the driven gear 4, it drives the main shaft 6 and the secondary shaft 7 fixed on it to rotate as a whole by a certain angle. This action, through the inner shaft 702 and the lamp assembly support plate 8, ultimately causes the vehicle's lamp assembly to deflect towards the turning side, thereby achieving supplemental lighting in the turning area. For example, when the left turn signal is turned on, the low beam will extend to the left, increasing the illumination range on the turning side.

[0036] Lateral rolling illumination: During the rotation of the main shaft 6, the shift fork 703 fixed on the inner shaft 702 will swing accordingly. When one side of the shift fork 703 contacts the corresponding lateral stop 10, under the limiting action of the lateral stop 10, the shift fork 703 will drive the inner shaft 702 to rotate around its own axis (i.e., the axis of the shaft 701) within the through hole 7011. The lateral rolling action will cause the lamp assembly support plate 8 and the lamp assembly to rise at an angle, effectively counteracting the downward shift of the illumination range caused by the side pressure of the vehicle body, and further expanding the effective illumination range.

[0037] Automatic Reset: When the steering ends and the vehicle resumes straight-line driving, the vehicle controller controls the drive motor 2 to rotate in the opposite direction, driving the main shaft 6 and the auxiliary shaft 7 back to their initial positions. During this process, the shift fork 703 disengages from the lateral stop 10. At this time, under the restoring force of the return spring 11, the shift fork 703 is pushed back to the central equilibrium position, thereby driving the inner shaft 702 and the lamp assembly support plate 8 to rotate, causing the roll angle of the lamp assembly to disappear and the light illumination angle to return to its initial state.

[0038] By using a shared drive motor 2 as the sole power source, the rotation of the main shaft 6 simultaneously drives horizontal steering and triggers roll compensation, while structures such as limit plates ensure the precision of the movement of each component. This highly integrated approach to the two degrees of freedom of illumination eliminates the need for a separate driver and control system for roll compensation. This results in a compact module structure, low manufacturing cost, and high reliability, making it ideal for widespread application in electric bicycles where space and budget are limited.
