Description

Technical Field

[0001] The present invention relates to the technical field of vehicle lamps, and in particular to an adaptive lamp module and a vehicle lamp assembly. Background Art

[0002] With the rapid development of the automotive industry, cars are becoming increasingly ubiquitous. Headlights, also known as headlamps, serve as the eyes of the car and are closely linked to safe driving at night or in bad weather. Conventional headlights have a fixed illumination range. When turning at night, the inability to adjust the illumination angle often creates a "blind spot" on the inside of the curve, posing a significant threat to the driver's nighttime safety.

[0003] In order to solve the problem that the lighting angle of ordinary car headlights cannot be adjusted, AFS (Adaptive Steering Headlights) has been developed in the field of vehicle lighting. It is also called adaptive lighting system or adaptive headlights. Adaptive steering headlights can automatically adjust the deflection of the headlights according to driving speed, steering angle, etc., so as to illuminate the turning area in advance and provide all-round safety lighting to ensure that the driver has the best visibility at any time, thereby enhancing the safety of driving in the dark.

[0004] Currently, the mainstream AFS module solution on the market uses a stepper motor to control the front angle deflection of the car headlights. However, the motor-driven light group rotation angle requires that the motor's drive end always maintain a transmission connection state. The vibration caused by the bumps during vehicle driving will directly act on the motor's drive end, which is very likely to cause damage to the motor's drive end, affecting the transmission connection between the motor and the light group, and thus shortening the service life of the AFS module. Summary of the Invention

[0005] In view of the above problems, it is necessary to provide an adaptive light module and a vehicle light assembly to address the existing technical problems.

[0006] In order to solve the problems of the prior art, the technical solution adopted by the present invention is:

[0007] The cam is secured to the base so that the cam can be rotated with the cam, and the cam can be locked to the base by locking the cam in the locking position.

[0008] Preferably, the driving unit includes a driving motor fixedly mounted on a fixed base, the working end of the driving motor is transmission-connected to a second gear that is exactly the same as the first gear, the second gear is located at the bottom of the fixed base and its axis is parallel to the axis of the first gear, two racks are slidingly mounted on the bottom of the fixed base, the racks are respectively located on both sides of the second gear and meshed with the second gear, and the horizontal connection line between the axis of the second gear and the axis of the first gear is parallel to the moving path of the rack; the driving motor drives the second gear to rotate so that the rack on one side contacts the first gear and meshes with the first gear, and the rack drives the first gear to rotate around its own axis.

[0009] Preferably, a limiting slide rail for slidingly installing the rack is provided at the bottom of the fixed base.

[0010] Preferably, a push rod is fixedly mounted on one end of the rack facing the lamp tube, the push rod extends along the length direction of the rack, a contact plate is provided on the sliding sleeve, and the end of the push rod facing the lamp tube is in contact with the contact plate.

[0011] Preferably, a guide rod extending along the length direction of the lamp tube is provided on the side of the contact plate away from the top rod, and the guide rod is inserted into a guide sleeve provided on the lamp tube. A compression spring is provided on the guide rod, and the compression spring elastically connects the guide sleeve and the contact plate. Positioning protrusions are provided on both sides of one end of the lamp tube facing the fixed base. The elastic force of the compression spring causes the sliding sleeve to move toward the fixed base until the contact plate fits the positioning protrusion. When the contact plate fits the positioning protrusion, the locking rod is inserted into the insertion hole.

[0012] Preferably, the lamp tube is provided with a plurality of first insertion holes on the side facing the fixed base, the first insertion holes are located on both sides of the axis, and an elastic member is coaxially inserted in each first insertion hole; the fixed base is provided with a plurality of second insertion holes which are respectively on the same straight line with the axis of the first insertion holes, and the other end of the elastic member is inserted in the second insertion hole.

[0013] Preferably, the driving unit further comprises a power supply module for supplying power to the driving motor, and the power supply module is fixedly mounted on the top of the fixed base.

[0014] Preferably, the light source includes a wick and a power transmission line connected to the wick, an inner channel connected to the lamp tube is provided in the shaft column, the opening of the inner channel is located at the top of the shaft column, and the power transmission line passes through the top opening of the inner channel and is electrically connected to the power supply module on the fixed base.

[0015] Preferably, a protective plug is provided at the top opening of the inner channel and is sleeved on the power transmission line.

[0016] A vehicle lamp assembly comprises a mounting shell, a lampshade and a plurality of adaptive lamp modules.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] First, a sliding sleeve is slidably installed on the lamp tube in the present invention, and the locking rod of the sliding sleeve remains inserted in the insertion hole of the arc-shaped limit block of the fixed base during the straight-line driving of the vehicle. This can eliminate the need for a driving unit to be connected to the shaft column and keep the angle between the lamp tube and the fixed base fixed. The vibration of the vehicle during driving is absorbed by the locking rod and the insertion hole, and will not affect the working end of the driving unit, thereby improving the service life of the driving unit and the entire lamp module.

[0019] Secondly, the driving unit in the present invention utilizes the distance in which one side rack moves toward the first gear but does not contact the first gear, so that the push rod preferentially pushes the contact plate to realize the movement of the sliding sleeve, thereby achieving that no matter what driving state the vehicle is in, as long as the driving motor is started to adjust the angle of the lamp tube, the locking rod will immediately disengage from the insertion hole, avoiding the problem of untimely unlocking due to manual operation or electronic control delay, and improving the reliability of the system.

[0020] Third, the transmission line connected to the wick in the present invention is stably located at the rotation axis of the lamp tube. When the lamp tube rotates, the torsional force on the transmission line is minimized, and the inner channel protects the outer wall of the transmission line, reducing surface wear of the transmission line and ensuring the service life and safety of the transmission line.

DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figures 1 to 11 :

[0035] An adaptive lamp module includes an optical unit 1, which includes a lamp tube 1a, a light source 1d, an optical lens 1e, and a focusing assembly 1f installed in the lamp tube 1a. A vertical shaft column 1b is provided at the non-light-emitting end of the lamp tube 1a, and a limit ring 1b2 is coaxially provided at both ends of the shaft column 1b. The lamp tube 1a is rotatably mounted on a fixed base 2 through the shaft column 1b. The limit ring 1b2 is installed in an axial hole 2a provided on the fixed base 2. A first gear 1b1 is coaxially provided at the bottom of the shaft column 1b. The fixed base 2 is provided with a driving gear for driving the first gear 1b1 to rotate around the axis of the shaft hole 2a. The moving unit 2b; the end of the fixed base 2 facing the lamp tube 1a is an arc-shaped limit block 2c whose axis is in the same straight line as the axial hole 2a, the lamp tube 1a is provided with an arc-shaped fitting surface 1a1 which fits the arc-shaped limit block 2c, and a sliding sleeve 1c is slidably installed on the lamp tube 1a, and the sliding sleeve 1c is provided with a locking rod 1c1 extending horizontally along the length direction of the lamp tube 1a, and the arc-shaped limit block 2c is provided with an insertion hole 2c1 which is in the same straight line as the locking rod 1c1. When the locking rod 1c1 of the sliding sleeve 1c is inserted into the insertion hole 2c1, the rotation angle of the lamp tube 1a and the fixed base 2 is locked.

[0036] The lamp module in the present application has a light source 1d in the lamp tube 1a for emitting light, and the optical lens 1e and the focusing component 1f cooperate to make the light emitted by the light source 1d be emitted through the light-emitting end of the lamp tube 1a. The lamp tube 1a is rotatably mounted on the fixed base 2 through the shaft column 1b, and the driving unit 2b drives the lamp tube 1a to rotate around the axis of the shaft column 1b to realize automatic deflection of the light when the vehicle turns, thereby illuminating the turning area in advance. The lamp tube 1a in this embodiment is slidably mounted with a sliding sleeve 1c, and the locking rod 1c1 of the sliding sleeve 1c remains inserted in the insertion hole 2c1 of the arc-shaped limit block 2c of the fixed base 2 during the straight-line driving of the vehicle. It is only necessary to ensure that the diameter of the locking rod 1c1 is the same as the inner diameter of the insertion hole 2c1, so that the angle between the lamp tube 1a and the fixed base 2 is kept fixed without the need for a transmission connection between the drive unit 2b and the shaft column 1b. The vibration of the vehicle during driving is absorbed by the locking rod 1c1 and the insertion hole 2c1, and will not affect the working end of the drive unit 2b, thereby improving the service life of the drive unit 2b and the entire lamp module. When the sensor detects that the vehicle is turning, the sliding sleeve 1c slides along the lamp tube 1a to disengage the locking rod 1c1 from the insertion hole 2c1 to release the lock of the lamp tube 1a, and the arc-shaped fitting surface 1a1 of the lamp tube 1a fits the surface of the arc-shaped limit block 2c and moves to cooperate with the shaft column 1b to be inserted into the shaft hole 2a, so that the lamp tube 1a can be rotated around the axis direction of the shaft column 1b.

[0037] In order to achieve the purpose of the driving unit 2b driving the lamp tube 1a to rotate, the following features are specifically set:

[0038] The driving unit 2b includes a driving motor 2b1 fixedly mounted on the fixed base 2, and the working end of the driving motor 2b1 is transmission-connected to a second gear 2b2 which is identical to the first gear 1b1. The second gear 2b2 is located at the bottom of the fixed base 2 and its axis is parallel to the axis of the first gear 1b1. Two racks 2b3 are slidingly mounted on the bottom of the fixed base 2, and the racks 2b3 are respectively located on both sides of the second gear 2b2 and meshed with the second gear 2b2. The horizontal connecting line between the axis of the second gear 2b2 and the axis of the first gear 1b1 is parallel to the moving path of the rack 2b3; the driving motor 2b1 drives the second gear 2b2 to rotate so that the rack 2b3 on one side contacts the first gear 1b1 and meshes with the first gear 1b1, and the rack 2b3 drives the first gear 1b1 to rotate around its own axis.

[0039] In this embodiment, when the vehicle turns, the drive motor 2b1 receives a control signal and starts operating. The working end of the drive motor 2b1 drives the second gear 2b2 to rotate in the corresponding direction. Since the second gear 2b2 is meshed with the two racks 2b3, the rotation of the second gear 2b2 pushes one side of the rack 2b3 toward the first gear 1b1 and into contact with the first gear 1b1 until it is fully meshed with the first gear 1b1. At this time, as the rack 2b3 continues to slide on the bottom of the fixed base 2, it is meshed with the first gear 1b1, driving the first gear 1b1 to rotate about its own axis. The first gear 1b1 is coaxially mounted on the shaft column 1b, thereby driving the shaft column 1b to rotate, causing the lamp tube 1a mounted on the shaft column 1b to rotate about the axis of the shaft hole 2a, thereby adjusting the headlight lighting angle.

[0040] In order to ensure that the movement path of the rack 2b3 is stable so that it can contact the first gear 1b1, the following features are specifically set:

[0041] A limiting slide rail 2d for slidingly mounting the rack 2b3 is provided at the bottom of the fixed base 2.

[0042] In this embodiment, 2d0 is provided at the bottom of 02 to limit 2b3. 2d0 ensures that 2b3 on both sides of 2b2 can stably contact 1b1 when moving along a horizontal straight line, and engage with 1b1 to drive 1b1 to rotate.

[0043] In order to automatically move the sliding sleeve 1c to a position where the locking rod 1c1 is disengaged from the insertion hole 2c1 when the driving unit 2b is started, the following features are specifically provided:

[0044] A push rod 2b4 is fixedly mounted on one end of the rack 2b3 facing the lamp tube 1a. The push rod 2b4 extends along the length direction of the rack 2b3. A contact plate 1c2 is provided on the sliding sleeve 1c. The push rod 2b4 is in contact with the contact plate 1c2 at one end facing the lamp tube 1a.

[0045] In this embodiment, when the drive motor 2b1 is activated, the second gear 2b2 rotates and drives one side of the rack 2b3 to slide toward the first gear 1b1. At this point, the push rod 2b4, fixed to the end of the rack 2b3 facing the lamp housing 1a, moves synchronously with the rack 2b3. Before the rack 2b3 contacts the first gear 1b1, its end engages the contact plate 1c2 on the sliding sleeve 1c and pushes the contact plate 1c2 and the sliding sleeve 1c to move, completely disengaging the locking rod 1c1 from the insertion hole 2c1 and releasing the angular lock between the lamp housing 1a and the fixed base 2. The rack 2b3 then continues to move until it begins to mesh with the first gear 1b1, driving the lamp housing 1a to rotate. This embodiment utilizes the gap between rack 2b3 moving toward first gear 1b1 but not contacting it to enable push rod 2b4 to preferentially push contact plate 1c2, moving sliding sleeve 1c. This allows drive unit 2b to automatically unlock lamp 1a before it rotates around shaft 1b when it is activated, ensuring that unlocking is synchronized with activation of drive unit 2b. Regardless of the vehicle's driving state, as soon as drive motor 2b1 activates to adjust the angle of lamp 1a, locking rod 1c1 immediately disengages from insertion hole 2c1. This prevents delayed unlocking due to manual operation or electronic control delays, improving system reliability.

[0046] In order to achieve the purpose of enabling the sliding sleeve to be reset into the insertion hole 2c1 of the locking rod 1c1 after the rack 2b3 of the driving unit 2b is reset, the following features are specifically provided:

[0047] A guide rod 1c3 extending along the length direction of the lamp tube 1a is provided on the side of the contact plate 1c2 away from the top rod 2b4. The guide rod 1c3 is inserted into the guide sleeve 1a2 provided on the lamp tube 1a. A compression spring 1c4 is sleeved on the guide rod 1c3. The compression spring 1c4 elastically connects the guide sleeve 1a2 and the contact plate 1c2. Positioning protrusions 1a3 are provided on both sides of the end of the lamp tube 1a facing the fixed base 2. The elastic force of the compression spring 1c4 causes the sliding sleeve 1c to move toward the fixed base 2 until the contact plate 1c2 is in contact with the positioning protrusion 1a3. When the contact plate 1c2 is in contact with the positioning protrusion 1a3, the locking rod 1c1 is inserted into the insertion hole 2c1.

[0048] When the drive motor 2b1 is activated, the rack 2b3 drives the push rod 2b4 to push the contact plate 1c2. The sliding sleeve 1c slides along the lamp tube 1a, and the guide rod 1c3 moves synchronously within the guide sleeve 1a2, compressing the compression spring 1c4 to store energy. The locking rod 1c1 now disengages from the insertion hole 2c1, allowing the lamp tube 1a to rotate freely. After the drive unit 2b completes the angle adjustment, the drive motor 2b1 reverses, resetting the rack 2b3. The lamp tube 1a rotates back to its original position, and the push rod 2b4 retracts with the rack 2b3. The compression spring 1c4 then releases its elastic potential energy, pushing the contact plate 1c2 toward the fixed base 2, causing the locking rod 1c1 to move against the surface of the arc-shaped stopper 2c. This allows the lamp tube 1a, driven by the sliding sleeve 1c, to rotate back to its original position until the axis of the locking rod 1c1 is aligned with the axis of the insertion hole 2c1. At this point, the locking rod 1c1, under the force of the compression spring 1c4, inserts into the insertion hole 2c1, locking the angle of the lamp tube 1a. When the contact plate 1c2 fits the positioning protrusion 1a3, the sliding sleeve 1c stops moving, and then the rack 2b3 continues to move to disengage from the surface of the contact plate 1c2, so that the bumpy vibration of the vehicle during driving will not be transmitted to the working end of the drive motor 2b1.

[0049] In order to facilitate the rotation and resetting of the lamp tube 1a, the following features are specifically set:

[0050] The lamp tube 1a is provided with a plurality of first insertion holes 1a4 on the side facing the fixed base 2. The first insertion holes 1a4 are located on both sides of the shaft column 1b, and an elastic member 1a5 is coaxially inserted in each first insertion hole 1a4; the fixed base 2 is provided with a plurality of second insertion holes 2e which are respectively on the same straight line as the axis of the first insertion holes 1a4, and the other end of the elastic member 1a5 is inserted in the second insertion hole 2e.

[0051] In this embodiment, when the lamp tube 1a rotates around the shaft 1b, the elastic member 1a5 on the side of the lamp tube 1a facing the fixed base 2 undergoes elastic deformation in the first insertion hole 1a4 and the second insertion hole 2e. The elastic member 1a5 can be a rubber column or a spring, etc. During the rotation of the lamp tube 1a, the elastic member 1a5 is squeezed or stretched, storing elastic potential energy. When the vehicle completes the turn and the drive unit 2b stops working, the elastic member 1a5 begins to release elastic potential energy until the lamp tube 1a returns to its initial position. Multiple elastic members 1a5 are distributed on both sides of the shaft 1b, providing balanced pulling or pushing forces for the reset of the lamp tube 1a from different directions, avoiding the lamp tube 1a from being offset or stuck during the reset process, ensuring that the lamp tube 1a can accurately return to its initial position, and ensuring the consistency and accuracy of the headlight lighting angle.

[0052] In order to provide power to the drive motor 2b1 and the light source 1d, the following features are specifically set:

[0053] The driving unit 2b further comprises a power supply module 2b5 for supplying power to the driving motor 2b1, which is fixedly installed on the top of the fixed base 2.

[0054] The light source 1d comprises a lamp wick 1d1 and a power transmission line 1d2 connected to the lamp wick 1d1, and the shaft column 1b is provided with an internal passage 1b3 communicating with the inside of the lamp barrel 1a, and the opening of the internal passage 1b3 is located at the top of the shaft column 1b, and the power transmission line 1d2 passes through the opening at the top of the internal passage 1b3 and is electrically connected to the power supply module 2b5 on the fixed base 2.

[0055] The power supply module 2b1 on the top of the fixed base 2 serves as a power source to provide power transmission for the driving motor 2b1 and the lamp wick 1d1 of the light source 1d when the vehicle is running. The lamp wick 1d1 located in the lamp barrel 1a has its power transmission line 1d2 extending to the outside of the lamp barrel 1a through the internal passage 1b3 of the shaft column 1b, and after being connected to the power supply module 2b5, the power transmission line 1d2 is located at the rotation axis position of the lamp barrel 1a when the lamp barrel 1a rotates, thereby reducing the influence on the power transmission line.

[0056] In order to stabilize the position of the power transmission line 1d2 in the internal passage 1b3 and reduce the wear of the power transmission line 1d2, the following features are specifically provided:

[0057] The top opening of the internal passage 1b3 is provided with a protective plug 1b4 sleeved on the power transmission line 1d2.

[0058] In this embodiment, the protective plug 1b4 sleeved on the power transmission line 1d2 is fixed at the top opening position of the internal passage 1b3, so that the power transmission line 1d2 is always kept in the same straight line with the axis of the internal passage 1b3, and therefore when the lamp barrel 1a rotates around the axis of the shaft column 1b, the power transmission line 1d2 is stably located at the rotation axis of the lamp barrel 1a, the twisting force on the power transmission line 1d2 is minimized, and the internal passage 1b3 protects the outer wall of the power transmission line 1d2, reduces the surface wear of the power transmission line 1d2, and ensures the service life and safety of the power transmission line 1d2.

[0059] A vehicle lamp assembly comprises a mounting shell 3, a lampshade 4 and a plurality of adaptive lamp modules.

[0060] Working principle: the sliding sleeve 1c is slidably installed on the lamp barrel 1a, the locking plug rod 1c1 of the sliding sleeve 1c is inserted into the insertion hole 2c1 of the arc-shaped limiting block 2c of the fixed base 2 during the straight driving of the vehicle, the angle between the lamp barrel 1a and the fixed base 2 is fixed, when the vehicle is steering, the driving motor 2b1 starts to operate after receiving the control signal. The working end of the driving motor 2b1 drives the second gear 2b2 to rotate in the corresponding direction, the rotation of the second gear 2b2 pushes the one side rack 2b3 to be close to the first gear 1b1 and contact with the first gear 1b1, the top rod 2b4 fixed at the end of the rack 2b3 towards the lamp barrel 1a moves synchronously with the rack 2b3. Before the rack 2b3 contacts the first gear 1b1, the end thereof abuts against the contact plate 1c2 on the sliding sleeve 1c and pushes the contact plate 1c2 and the sliding sleeve 1c to move, so that the locking plug rod 1c1 is completely separated from the position of the insertion hole 2c1, and the angle locking between the lamp barrel 1a and the fixed base 2 is released. Then, the rack 2b3 continues to move until it starts to mesh with the first gear 1b1, drives the lamp barrel 1a to rotate, and adjusts the illumination angle of the headlamp.

[0061] The above embodiments only express one or several embodiments of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
