Description

Technical Field

[0001] This invention relates to the field of automotive headlight technology, specifically to an integrated high and low beam headlight module for automobiles. Background Technology

[0002] With the continuous development of automotive headlight technology, the integrated high and low beam lighting system has become increasingly complex, and the application of various conventional fixed headlight heat dissipation components has increased accordingly. The tasks of thermal management and space adaptation of the headlight assembly have also become more and more arduous.

[0003] Fixed heat sink fins are typically used to dissipate heat generated by the control module. However, when assembling headlights within the limited installation space of a vehicle and during daily driving, heat dissipation components often need to have flexible and compact external contours to adapt to the vehicle's space and manage heat efficiently. During this process, assembly personnel must expend considerable effort to avoid accommodating surrounding components within the confined space for structural matching. If the heat dissipation component is too large and its shape remains fixed, it may cause spatial interference between the headlight assembly and the inner wall of the lamp housing or surrounding decorative covers. Furthermore, excessively large fixed gaps can easily allow external dust or mud to intrude. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an integrated high and low beam headlight module for automobiles, which solves the technical problems of the fixed volume of the headlight heat dissipation structure, which easily interferes with the installation space, and the poor dustproof effect of the gap, which easily induces insulation damage and overheating risks.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated high and low beam headlight module for automobiles, comprising an illumination body, a control module disposed on one side of the illumination body, and a support base disposed on the outside of the control module; heat dissipation fins arranged in a ring and movably disposed on the support base; a drive assembly disposed within the support base; a transmission component movably disposed on the support base and connecting the drive assembly and the heat dissipation fins; and, the drive assembly, when heated, drives the transmission component to displace, thereby driving the heat dissipation fins to unfold in a direction away from the axis of the support base.

[0006] Preferably, the drive assembly includes a guide housing fixed within the bearing base and a piston slidably disposed within the guide housing; the transmission component includes a transmission push rod connected to the piston and a constraint limiting disc fixed to the end of the transmission push rod.

[0007] Preferably, the support base is provided with a rotating component, the heat dissipation fins are fixed on the rotating component, and a linkage rod is fixed on the rotating component. The linkage rod abuts against the outer periphery of the constraint limiting disk to limit the angle of the heat dissipation fins.

[0008] Preferably, a torsional elastic element is connected between the rotating component and the bearing base, and a linear elastic element is provided inside the guide housing for pulling the pushed piston back to its original position.

[0009] Preferably, it also includes an auxiliary heat dissipation component, which includes a receiving cavity opened in the bearing base and a guide rod fixed in the receiving cavity, with a vibration block slidably sleeved on the guide rod.

[0010] Preferably, the upper and lower sides of the vibrating block are provided with elastic airbags fixed in the accommodating cavity, and the elastic airbags are connected to multiple guide holes opened on the bearing base and facing the heat dissipation fins.

[0011] Preferably, the end of the transmission component is provided with an elastic locking component, which contacts the vibration block and limits and fixes the vibration block.

[0012] Preferably, it further includes a delay component disposed within the drive assembly, the delay component including a flow-blocking baffle fixedly connected to the guide housing, and a damping chamber formed between the flow-blocking baffle and the pushed piston.

[0013] Preferably, the damping chamber is filled with damping fluid, and the flow-blocking baffle has a through throttling hole.

[0014] Preferably, a compensation plate is provided on the side of the flow-blocking baffle away from the pushed piston, and an energy storage and reset component is provided between the compensation plate and the flow-blocking baffle.

[0015] This invention provides an integrated high and low beam headlight module for automobiles. It has the following beneficial effects:

[0016] 1. This invention solves the problems of fixed volume, susceptibility to dust contamination, and space occupation of the heat dissipation structure of the headlight module in the prior art by setting up a driving component and a ring-shaped movable heat dissipation fin. This achieves the technical effect of shrinking to prevent dust and avoid space at low temperatures and expanding outward to increase the heat dissipation area at high temperatures, thereby achieving the ultimate goal of efficiently dissipating heat on demand for the control module of the integrated high and low beam headlight.

[0017] 2. This invention employs an auxiliary heat dissipation component that includes a reciprocating vibration block, an elastic airbag, and a guide hole, enabling the headlight module to convert the vibration of the vehicle driving on bumpy roads into the power of airflow, thereby improving the heat exchange efficiency of the heat dissipation fin surface.

[0018] 3. The present invention employs a delay component consisting of a flow-blocking baffle and a damping chamber located inside the drive assembly. This allows the pushed piston to slow down its displacement response speed when faced with sudden changes in external temperature due to the flow resistance of the damping fluid flowing through the throttling orifice. This effectively avoids excessive fatigue wear of the torsional elastic component and rotating component caused by the frequent expansion and contraction of the heat dissipation fins in a short period of time.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1, please refer to the appendix. Figure 1 -Appendix Figure 2This is the first embodiment of the present invention. This embodiment provides an integrated high and low beam headlight module for automobiles, including an illumination body 100 for emitting illumination light, a control module 200 disposed on one side of the illumination body 100 for controlling the working state of the illumination body 100, a support base 310 disposed outside the control module 200 for supporting a heat dissipation structure, heat dissipation fins 320 arranged in a ring around the axis of the support base 310 and movably disposed on the support base 310, a drive component 400 disposed inside the support base 310 and capable of sensing temperature changes, and a transmission component 500 movably disposed on the support base 310 and connected between the drive component 400 and the heat dissipation fins 320.

[0030] The support base 310 is a disc-shaped shell structure with one end face of the control module 200 being attached to the end face of the control module 200 away from the lighting body 100. The periphery of the support base 310 is provided with an interface for installing heat dissipation fins 320.

[0031] Please see the appendix Figure 1 and attached Figure 2 The heat dissipation fins 320 are made of metal sheets with good thermal conductivity. Each heat dissipation fin 320 is hinged to the support base 310 through a corresponding interface, so that each heat dissipation fin 320 can swing relative to the support base 310 around a pivot axis at its end.

[0032] The drive assembly 400 is fixedly installed in the internal cavity of the support base 310 and located near the axis of the support base 310. The drive assembly 400 is filled with a thermal expansion medium, which expands in volume after absorbing heat from the control module 200.

[0033] The transmission component 500 is arranged axially along the support base 310 and extends through the end face opening of the support base 310 to the outside of the support base 310. The first end of the transmission component 500 extends into the drive assembly 400 and forms an abutment engagement with the moving part of the drive assembly 400. The second end of the transmission component 500 extends to the height position of the end of the heat dissipation fin 320.

[0034] When the drive assembly 400 is heated, the internal pressure increases and the drive component is displaced along the axial direction of the support base 310. This pushes the transmission component 500 to displace in the direction away from the axis of the support base 310, that is, in the axial outward direction. The outward displacement of the transmission component 500 releases the constraint on the swing angle of the heat dissipation fins 320, so that the heat dissipation fins 320 unfold outward around the pivot axis in the direction away from the axis of the support base 310.

[0035] Please see the appendix Figure 1It should be noted that when the temperature is low, the heat dissipation fins 320 remain in a contracted state, retracting towards the axis of the support base 310. In the contracted state, the outer contour of each heat dissipation fin 320 is drawn inward, keeping the radial dimension of the headlight assembly within a small range. This facilitates assembly within the limited installation space of the vehicle headlight and avoids spatial interference between the heat dissipation fins 320 and other surrounding components such as the inner wall of the lamp housing or the decorative cover after they extend. Furthermore, after the contracted heat dissipation fins 320 move closer to each other circumferentially, the gap between adjacent heat dissipation fins 320 is reduced. External dust or mud is less likely to enter the joint between the support base 310 and the control module 200 through the gap, which helps maintain the cleanliness of the surface of the control module 200 and reduces the risk of decreased insulation performance or local overheating caused by the accumulation of contaminants.

[0036] In this embodiment, the drive component 400 senses temperature changes and drives the transmission component 500 to move axially. The transmission component 500 then releases the swing constraint on the heat dissipation fins 320, allowing the heat dissipation fins 320 to expand outward when the temperature rises to increase the heat dissipation area, thereby achieving on-demand heat dissipation for the control module 200.

[0037] Example 2, please refer to the appendix. Figure 3 -Appendix Figure 7 This is the second embodiment of the present invention. Based on the previous embodiment, the driving assembly 400 further includes a guide housing 410 and a thrust piston 420. The guide housing 410 is fixedly disposed inside the bearing base 310 with its axis coinciding with the axis of the bearing base 310. The inner wall of the guide housing 410 forms a smooth guide cylindrical surface.

[0038] The piston 420 is cylindrical in shape and is disposed inside the guide housing 410 in a sliding fit manner. The piston 420 divides the internal space of the guide housing 410 into a temperature sensing chamber near the closed end and a transmission chamber near the extrusion end. The temperature sensing chamber is filled with a thermal expansion medium that expands in volume when the temperature rises.

[0039] Please see the appendix Figure 3 and attached Figure 4 The transmission component 500 includes a transmission push rod 510 and a constraint limiting disk 520. The transmission push rod 510 is a slender rod-shaped structure extending axially. The first end of the transmission push rod 510 passes through the pressing end of the guide housing 410 and extends into the interior of the guide housing 410, forming a fixed connection with the end face of the pushed piston 420 facing the pressing end. The second end of the transmission push rod 510 extends axially outward to the outside of the bearing base 310.

[0040] Specifically, a rotating component 321 is provided on the support base 310 corresponding to the position of each heat dissipation fin 320. The rotating component 321 is a rotating block structure set on the support base 310 via a rotating shaft. The end of the heat dissipation fin 320 is fixedly inserted into a preset slot on the rotating component 321 and locked with fasteners, so that the heat dissipation fin 320 swings synchronously around the axis of the rotating shaft with the rotating component 321.

[0041] Each rotating component 321 is also fixedly provided with a linkage rod 322. The linkage rod 322 extends outward from the outer periphery of the rotating component 321 and bends towards the outer periphery of the constraint limiting disk 520. The end face of the linkage rod 322 is constructed to form an arc-shaped abutment surface that matches the outer periphery of the constraint limiting disk 520. When the heat dissipation fins 320 are in the retracted state, the end face of the linkage rod 322 forms a surface contact abutment with the outer periphery of the constraint limiting disk 520. The rotation angle of the rotating component 321 is constrained by the limiting effect of the constraint limiting disk 520 on the linkage rod 322, thereby maintaining the retracted posture of the heat dissipation fins 320.

[0042] Please see the appendix Figure 5 Preferably, in order to reduce the contact friction between the end face of the linkage rod 322 and the outer peripheral surface of the constraint limiting disk 520, a freely rotatable ball or roller is embedded at the end of the linkage rod 322, and part of the surface of the ball or roller protrudes from the end face of the linkage rod 322 and forms rolling contact with the outer peripheral surface of the constraint limiting disk 520.

[0043] A torsional elastic element 323 is connected between the rotating component 321 and the bearing base 310. The torsional elastic element 323 is a torsion spring sleeved on the rotating shaft of the rotating component 321. The first end of the torsion spring is fixed on the rotating component 321, and the second end of the torsion spring is fixed on the bearing base 310. The torsion spring applies a torque to the rotating component 321 in the direction of outward expansion of the heat dissipation fins 320 around the axis of rotation.

[0044] The guide housing 410 is provided with a linear elastic element 430, which is a compression spring. The linear elastic element 430 applies an elastic tension or pressure to the pushed piston 420 in the direction of the compression end of the guide housing 410, so that the pushed piston 420 is kept in the initial position near the closed end when it is not driven by thermal expansion.

[0045] Please see the appendix Figure 3 and attached Figure 5In the initial state, that is, when the control module 200 does not generate a lot of heat and the temperature of the thermal expansion medium inside the drive component 400 is low, the pushed piston 420 is held in the initial position close to the closed end of the guide housing 410 under the elastic action of the linear elastic element 430. The pushed piston 420 drives the constraint limiting disk 520 to be held in the initial axial position close to the bearing base 310 through the transmission push rod 510. At this time, the outer peripheral surface of the constraint limiting disk 520 abuts against the end face of all the linkage rods 322 at the same time, constraining the linkage rods 322 at an angle position deflected towards the axis. The rotating part 321 is constrained by the linkage rod 322 and overcomes the torque of the torsional elastic element 323 to remain stationary. The heat dissipation fins 320 are held in a contracted state that is folded towards the axis of the bearing base 310.

[0046] Please see the appendix Figure 7 When the control module 200 generates heat and the temperature rises, the thermal expansion medium in the temperature sensing chamber of the guide housing 410 expands due to the heat. The expansion medium pushes the piston 420 to overcome the elastic force of the linear elastic element 430 and slide along the inner wall of the guide housing 410 away from the closed end, i.e. towards the pressing end of the guide housing 410. The sliding of the piston 420 drives the constraint limiting disk 520 to move axially away from the bearing base 310 through the transmission push rod 510. After the outer peripheral surface of the constraint limiting disk 520 moves outward and leaves the end face of the linkage rod 322, the linkage rod 322 loses the resistance of the constraint limiting disk 520. Under the torque drive of the torsional elastic element 323, the rotating element 321 rotates around the axis of rotation. The rotating element 321 drives the heat dissipation fins 320 to swing and unfold around the axis of rotation away from the axis of rotation.

[0047] Conversely, when the temperature drops, the thermal expansion medium contracts, and the linear elastic element 430 pushes the pushed piston 420 back to its initial position. The pushed piston 420 drives the constraint limiting disk 520 back to its original position through the transmission push rod 510. The outer peripheral surface of the constraint limiting disk 520 abuts against the end face of the linkage rod 322 again and pushes the linkage rod 322 and the rotating element 321 to overcome the torque of the torsional elastic element 323 and rotate back to the initial angle. The heat dissipation fins 320 retract to the contracted state.

[0048] Example 3, please refer to the appendix. Figure 5 -Appendix Figure 7 This is the third embodiment of the present invention. This embodiment is based on embodiment 2. Further, the auxiliary heat dissipation component 700 includes a receiving cavity opened inside the bearing base 310, a guide rod 710 fixedly disposed inside the receiving cavity, a vibration block 720 slidably sleeved on the guide rod 710, and elastic airbags 730 disposed on the upper and lower sides of the vibration block 720.

[0049] The receiving cavity is a hollow structure formed inside the bearing base 310. The receiving cavity is located at the axial center of the bearing base 310 and extends axially. The receiving cavity and the guide shell 410 are spatially adjacent but not connected.

[0050] Please see the appendix Figure 6 The guide rod 710 is a smooth guide rod with both ends fixed to the inner walls of the receiving cavity. The axial direction of the guide rod 710 is arranged perpendicular to the axial direction of the bearing base 310, or consistent with the vertical vibration direction of the vehicle.

[0051] The vibrating block 720 has a through guide hole in the middle and can be slidably sleeved on the outer circumferential surface of the guide rod 710 through the guide hole. The vibrating block 720 can slide freely back and forth along the axial direction of the guide rod 710 under the action of external force.

[0052] The vibrating block 720 is equipped with a suspension elastic element inside. The suspension elastic element is a compression spring or tension spring sleeved on the outer circumferential surface of the guide rod 710. The first end of the suspension elastic element is fixed to the inner wall of the vibrating block 720, and the second end of the suspension elastic element is fixed to the end of the guide rod 710 or the inner wall of the receiving cavity. The suspension elastic element is used to apply an elastic restoring force to restore the vibrating block 720 to the equilibrium position when it deviates from the equilibrium position.

[0053] Please see the appendix Figure 6 It should be noted that when the vehicle is traveling on a bumpy road, the vibrating block 720 slides back and forth along the guide rod 710 under the action of inertial force. The back and forth sliding of the vibrating block 720 generates an alternating squeezing effect on the elastic airbags 730 set on its upper and lower sides.

[0054] The elastic airbag 730 is a hollow bladder structure made of elastic deformable material. The bottom of each elastic airbag 730 is fixedly installed on the inner wall of the receiving cavity, and the interior of the elastic airbag 730 forms a pumping chamber that can contain gas.

[0055] The support base 310 has multiple flow guide holes 312. The first end of the flow guide hole 312 is connected to the pump chamber of the elastic airbag 730, and the second end of the flow guide hole 312 passes through the outer wall of the support base 310 and opens toward the gap between adjacent heat dissipation fins 320.

[0056] The end of the transmission component 500 is provided with an elastic locking component 530. The elastic locking component 530 is an elastic telescopic pin or elastic claw structure fixed on the outer peripheral surface of the transmission push rod 510. The free end of the elastic locking component 530 extends into the cavity and contacts the outer surface of the vibration block 720 in the initial state to limit the sliding of the vibration block 720.

[0057] Please see the appendix Figure 6In the initial state where the temperature does not exceed the set threshold, the transmission push rod 510 is in an axial position close to the bearing base 310. The elastic locking member 530 is in a locked position along with the transmission push rod 510 and contacts the vibration block 720. The elastic locking member 530 limits and fixes the vibration block 720 in the middle balance position of the receiving cavity, preventing the vibration block 720 from sliding on the guide rod 710.

[0058] When the temperature rises and the transmission push rod 510 is pushed outward along the axis by the push piston 420, the transmission push rod 510 drives the elastic locking member 530 away from the vibration block 720. The free end of the elastic locking member 530 exits the receiving cavity or retracts to a position that does not contact the vibration block 720. The vibration block 720 is unlocked and slides back and forth along the guide rod 710 under the action of vehicle vibration.

[0059] Both the air inlet and outlet of the elastic airbag 730 are equipped with one-way diaphragms. The one-way diaphragm is a diaphragm valve structure that allows gas to flow in one direction. The one-way diaphragm installed at the air inlet only allows external gas to enter the elastic airbag 730, and the one-way diaphragm installed at the air outlet only allows the gas inside the elastic airbag 730 to be discharged outward. This configuration causes external air to be continuously drawn into the elastic airbag 730 and then forced out when the vibrating block 720 slides and squeezes the elastic airbag 730, forming a one-way airflow. This airflow is blown out from the second end of the guide hole 312 and passes through the gap between adjacent heat dissipation fins 320, carrying away the heat on the surface of the heat dissipation fins 320.

[0060] Example 4, please refer to the appendix. Figure 8 This is the fourth embodiment of the present invention. This embodiment is based on embodiment 2 or embodiment 3. Further, the delay component 800 includes a flow-blocking baffle 810 fixedly disposed inside the guide housing 410. The flow-blocking baffle 810 is an annular plate structure arranged perpendicular to the axial direction of the guide housing 410. The outer peripheral edge of the flow-blocking baffle 810 is fixedly connected to the inner wall of the guide housing 410 and keeps sealed. The flow-blocking baffle 810 is located on the side of the pushed piston 420 away from the closed end of the guide housing 410, that is, the pushed piston 420 is located in the space between the inner wall of the closed end of the guide housing 410 and the flow-blocking baffle 810.

[0061] Please see the appendix Figure 8 The damping chamber 820 is filled with damping fluid, which is a liquid medium with a certain viscosity. The flow-blocking baffle 810 has at least one throttling hole 811 that penetrates the thickness direction of the flow-blocking baffle 810.

[0062] When the pushed piston 420 expands due to heat and slides along the inner wall of the guide housing 410 toward the flow-blocking baffle 810, the pushed piston 420 squeezes the damping fluid in the damping chamber 820. The damping fluid is forced to flow through the throttling orifice 811 on the flow-blocking baffle 810 to the other side of the flow-blocking baffle 810. Since the flow area of ​​the throttling orifice 811 is much smaller than the cross-sectional area of ​​the damping chamber 820, the damping fluid generates flow resistance when it flows through the throttling orifice 811. This flow resistance acts on the pushed piston 420, slowing down the displacement speed of the pushed piston 420, thereby causing a lag in the movement of the transmission push rod 510 and the constraint limiting plate 520.

[0063] Without the delay component 800, when the temperature changes suddenly, the thermal expansion medium inside the drive component 400 will expand or contract rapidly. The pushed piston 420 will respond and drive the transmission component 500 to move, causing the heat dissipation fins 320 to frequently expand and contract in a short period of time. Long-term frequent opening and closing will accelerate the fatigue wear of the rotating component 321 and the torsional elastic component 323.

[0064] Please see the appendix Figure 8 The throttling orifice 811 is provided with a pressure-sensitive deformation element, which is a ring or sheet-like component made of elastic material embedded in the inner wall of the throttling orifice 811. The pressure-sensitive deformation element can undergo recoverable elastic deformation when subjected to damping fluid pressure.

[0065] When the temperature rises sharply and the hydraulic pressure inside the damping chamber 820 increases rapidly, the pressure-sensitive deformation element expands and deforms after being subjected to hydraulic pressure exceeding the preset threshold. The deformation of the pressure-sensitive deformation element increases the flow area of ​​the throttling orifice 811. After the flow area increases, the flow resistance of the damping fluid through the throttling orifice 811 decreases, the displacement speed of the pushed piston 420 increases, and the unfolding speed of the heat dissipation fins 320 increases accordingly.

[0066] Please see the appendix Figure 8 A compensation plate 840 is provided on the side of the flow-blocking baffle 810 away from the pushed piston 420. The compensation plate 840 is a plate-shaped component that is slidably disposed inside the guide housing 410. The compensation plate 840 is located on the side of the flow-blocking baffle 810 away from the pushed piston 420. An energy storage and reset component is provided between the compensation plate 840 and the flow-blocking baffle 810. The energy storage and reset component is a compression spring or an elastic washer.

[0067] The compensation plate 840 moves toward the flow-blocking baffle 810 under the push of the energy storage and reset component to compensate for the volume change caused by the backflow of the damping fluid.

[0068] Without the compensation plate 840 and the energy storage reset component, a negative pressure zone may be generated inside the guide housing 410 due to volume changes when the damping fluid flows back. The negative pressure will cause the pushed piston 420 to fail to reset properly, which will affect the reset accuracy of the linear elastic component 430 on the pushed piston 420.

[0069] Based on the above embodiments, the complete working process of this device is as follows:

[0070] In the initial state, the pushed piston 420 is in the initial position near the closed end of the guide housing 410 under the pull of the linear elastic member 430. The pushed piston 420 holds the constraint limiting disk 520 in an axial position near the bearing base 310 through the transmission push rod 510. The outer peripheral surface of the constraint limiting disk 520 abuts against the ends of each linkage rod 322, constraining each heat dissipation fin 320 in a contracted state that converges toward the axis of the bearing base 310. The elastic locking member 530 is in the locked position with the transmission push rod 510 and contacts the vibration block 720, limiting the vibration block 720 to the middle position of the receiving cavity.

[0071] When the control module 200 generates heat, the heat is conducted through the support base 310 to the temperature sensing chamber of the guide housing 410. The thermal expansion medium in the temperature sensing chamber expands due to the heat, and the expansion medium pushes the thrust piston 420 to slide along the inner wall of the guide housing 410 toward the flow-blocking baffle 810. The thrust piston 420 squeezes the damping fluid in the damping chamber 820. The damping fluid slowly flows to the side of the compensation plate 840 through the throttling orifice 811 controlled by the pressure-sensitive deformation element. The displacement of the thrust piston 420 is moderately delayed due to the flow resistance of the damping fluid.

[0072] After the piston 420 overcomes the damping delay, it pushes the transmission push rod 510 to move outward along the axis. The transmission push rod 510 drives the constraint limiting plate 520 away from the bearing base 310. After the linkage rod 322 loses the resistance of the constraint limiting plate 520, the rotating part 321 rotates under the drive of the torsional elastic part 323 and drives the heat dissipation fins 320 to unfold away from the axis. At the same time, the transmission push rod 510 drives the elastic locking part 530 away from the vibration block 720, releasing the lock on the vibration block 720.

[0073] Under the vibration of the vehicle, the vibrating block 720 slides back and forth along the guide rod 710 and alternately squeezes the elastic airbags 730 on the upper and lower sides. The elastic airbags 730 continuously squeeze air out of the guide hole 312 through the one-way diaphragm. The airflow sweeps between the adjacent heat dissipation fins 320 and carries away the heat.

[0074] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
