DETAILED DESCRIPTION

[0015] The embodiment of the present application discloses an automatic adjustment mechanism for high and low beams of an LED lens module. When the low beam is selected, the light baffle 2 is in a horizontal state, and the arc-shaped heat conducting plate 51 and the heat dissipating fins 52 on the light baffle 2 are separated.

When it is high beam, the light baffle 2 is in a downward swing state. At this time, the oblique insert strips 522 on the heat dissipation fins 52 on the light baffle 2 are tilted downward and inserted between the two side clips 511. At this time, the arc-shaped heat conductive plate 51 and the heat dissipation fins 52 on the light baffle 2 are in a connected state, and the heat transfer routes become more, which further accelerates the heat transfer, thereby accelerating the heat dissipation in the inner cavity of the LED lens module.

[0016] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] Reference Figure 1 and Figure 2 An automatic adjustment mechanism for high and low beams of an LED lens module comprises a support rod 1, a light baffle 2, a solenoid valve 3, a toggle member 4 and a heat dissipation assembly 5. The support rod 1, the solenoid valve 3 and the toggle member 4 are all mounted on a base frame 101 of the LED lens module. A lamp cup 104 and a lens lens 106 are mounted on both sides of the base frame 101, respectively. An LED lamp bead 105 is mounted in the lamp cup 104. After the LED lamp bead 105 emits light, it is reflected by the lamp cup 104, and finally the light is emitted through the lens lens 106. A driver 102 and a heat dissipation substrate 103 are mounted on the top of the outer wall of the lamp cup 104. The heat dissipation substrate 103 can dissipate heat for the driver 102. Specifically, a heat dissipation fan can also be mounted on the heat dissipation substrate 103. In addition, the driver 102 can play a role in power conversion and voltage stabilization.

[0018] Reference Figure 2 As shown, the support rod 1 is in the shape of a circular tube, and support plates 12 are fixedly connected to both sides of the base frame 101. The two ends of the support rod 1 are respectively fixed to the support plates 12 on both sides of the base frame 101, and the support rod 1 and the support plate 12 can be made of aluminum. The light blocking plate 2 is made of a metal with high thermal conductivity. In a specific implementation, the light blocking plate 2 can be made of aluminum. The light blocking plate 2 is a sheet plate with an arc-shaped cross section. The two ends of the light blocking plate 2 are in the shape of vertical plates, and the vertical plates at both ends of the light blocking plate 2 are perpendicular to the support rod 1. The vertical plates at both ends of the light blocking plate 2 are rotatably arranged between the support rod 1, so that the light blocking plate 2 can swing on the support rod 1.

[0019] Continue to refer to Figure 2 and Figure 3 The solenoid valve 3 is installed in the middle of the base frame 101 and is located below the support rod 1. An extension strip 21 is extended from the bottom of the vertical plate on one side of the light shielding plate 2, and a tooth 211 is provided on the extension strip 21. The toggle member 4 includes a sleeve 41, a rotating column 42 and a fan-shaped plate 43. The sleeve 41 is fixed on the push rod 31 of the solenoid valve 3, and the axis of the push rod 31 of the solenoid valve 3 is parallel to the axis of the support rod 1. The end of the sleeve 41 away from the push rod 31 of the solenoid valve 3 is in the shape of an opening 11, and a limiting column 411 is fixed to the end of the sleeve 41 away from the solenoid valve 3, and the axis of the limiting column 411 is perpendicular to the axis of the sleeve 41. One end of the limiting column 411 is located on the outside of the sleeve 41, and the other end is located on the inside of the sleeve 41. The rotating column 42 is inserted into the end of the opening 11 of the sleeve 41, and the rotating column 42 and the sleeve 41 are fitted with a gap. A path groove 421 is provided on the rotating column 42, and the limit column 411 on the sleeve 41 is inserted into the path groove 421 of the rotating column 42. The end of the rotating column 42 away from the sleeve 41 is rotatably arranged on the support plate 12 on one side, and the rotating column 42 is located on the side of the extension strip 21 away from the light shielding plate 2. In addition, a swing fan 423 is fixed on the rotating shaft 422 of the rotating column 42, and the swing fan 423 is used to fan the heat dissipation component 5. The fan-shaped plate 43 is fixed on the outer wall of the rotating shaft 422 of the rotating column 42, and a tooth 2 431 is provided on the fan-shaped plate 43, and the tooth 2 431 is meshed with the tooth 1 211 on the extension strip 21, so that the rotation of the rotating column 42 drives the fan-shaped plate 43 to rotate. When the push rod 31 of the solenoid valve 3 is extended, the limit column 411 on the sleeve 41 moves in the path groove 421 of the rotating column 42, and causes the rotating column 42 to rotate, and the rotation angle is the switching angle of the light shielding plate 2 between the near and high beams.

[0020] The rotation of the rotating column 42 will drive the fan-shaped plate 43 to rotate. Since the tooth 2 431 on the fan-shaped plate 43 is meshed with the tooth 1 211 on the extension strip 21, the fan-shaped plate 43 will drive the extension strip 21 to swing, and then the light blocking plate 2 will swing, thereby realizing the switching of the light blocking plate 2 between low beam and high beam. When high beam is needed, the light blocking plate 2 swings down, and the light blocking plate 2 is inclined at this time. When low beam is needed, the light blocking plate swings up, and the light blocking plate 2 is horizontal to block the light.

[0021] Reference Figure 2 , Figure 4 as well as Figure 5As shown, the heat dissipation assembly 5 includes an arc-shaped heat conducting plate 51, heat dissipation fins 52, a copper tube 1 53 and a copper tube 2 54. The arc-shaped heat conducting plate 51 is located below the light baffle 2. The material of the arc-shaped heat conducting plate 51 can be consistent with the material of the light baffle 2. The arc-shaped heat conducting plate 51 is located below the inner side of the light baffle 2 and is inclined. The two ends of the arc-shaped heat conducting plate 51 are respectively fixed to the two ends of the support rod 1. When the light baffle 2 is in a downward inclined state, the lower bottom surface of the light baffle 2 is parallel to the arc-shaped heat conducting plate 51. A plurality of clips 511 are integrally formed on the arc-shaped heat conducting plate 51, and the plurality of clips 511 are composed of two. The material of the heat dissipation fin 52 is consistent with that of the arc-shaped heat conducting plate 51. The heat dissipation fin 52 is fixed on the inner wall of the light baffle 2. A plurality of heat dissipation fins 52 are provided and are equidistantly arranged on the arc-shaped heat conducting plate 51. The heat dissipation fin 52 includes an integrally formed main fin 521 and an oblique insertion strip 522. The main fin 521 is a square piece and is vertically fixed on the inner wall of the light baffle 2. The oblique insertion strip 522 is integrally formed on the end surface of the main fin 521 away from the arc-shaped heat conducting plate 51. The oblique insertion strip 522 is inclined downward, and when the baffle is swung down, the oblique insertion strip 522 is inserted between the two side clips 511.

[0022] When the light is at low beam, the light baffle 2 is in a horizontal state, and the arc-shaped heat-conducting plate 51 and the heat-dissipating fins 52 on the light baffle 2 are in a separated state. At this time, the clips 511 on the arc-shaped heat-conducting plate 51 and the heat-dissipating fins 52 on the light baffle 2 will absorb the heat in the LED lens module, and the heat on the heat-dissipating fins 52 will be transferred to the light baffle 2, and then transferred to the support rod 1, and the clips 511 on the arc-shaped heat-conducting plate 51 will also absorb the heat in the LED lens module, and the heat will also be transferred to the support rod 1, and finally the support rod 1 will transfer the heat to the base frame 101, thereby accelerating the heat dissipation in the inner cavity of the LED lens module.

[0023] When the high beam is on, the light baffle 2 is in a downward swing state. At this time, the oblique insert strips 522 on the heat dissipation fins 52 on the light baffle 2 are tilted downward and inserted between the two side clips 511. At this time, the arc-shaped heat conductive plate 51 and the heat dissipation fins 52 on the light baffle 2 are in a connected state, and the heat transfer routes become more, which further accelerates the heat transfer, thereby accelerating the heat dissipation in the inner cavity of the LED lens module.

[0024] Continue to refer to Figure 2 , Figure 4 as well as Figure 5As shown, there are two copper tubes 1 53, which are respectively located on both sides of the inner cavity of the support rod 1. Openings 11 are provided on both sides of the support rod 1. One end of the copper tube 1 53 passes through the opening 11 and is connected to the arc-shaped heat-conducting plate 51, and the other end passes through the end opening 11 at one end of the support rod 1. The end of the copper tube 1 53 away from the support rod 1 is connected to the heat dissipation substrate 103 of the driver 102 in the LED lens module. The copper tube 2 54 is located below the support rod 1. One end of the copper tube 2 54 is Y-shaped and fixed on the arc-shaped heat-conducting plate 51, and the other end passes through the support plate 12 on one side and is connected to the copper tube 1 53 on that side. In a specific implementation, coolant can be added to both the copper tube 1 53 and the copper tube 2 54, which can play a role in adding cooling.

[0025] The copper tube 1 53 and the copper tube 2 54 can accelerate the heat transfer on the arc-shaped heat-conducting plate 51, and can transfer the heat to the heat dissipation substrate 103 of the driver 102, thereby further accelerating the heat dissipation.

[0026] Continue to refer to Figure 4 and Figure 5 As shown, a triangular block 13 is fixedly connected to the support plate 12 on the side of the solenoid valve 3 facing away from the toggle member 4. The triangular block 13 has a central hole inside, and a plurality of heat-conducting fins 131 are fixedly connected between a side wall of the triangular block 13 and the base frame 101. The heat-conducting fins 131 not only connect the triangular block 13 and the base frame 101, but also absorb the heat in the LED lens module, thereby accelerating heat transfer, and more firmly connecting the triangular block 13, the support plate 12 and the base frame 101, thereby improving the stability of the base frame 101.

[0027] This application can explain its functional principle through the following operation methods: During the extension of the push rod 31 of the solenoid valve 3, the limit column 411 on the sleeve 41 moves in the path groove 421 of the rotating column 42, and causes the rotating column 42 to rotate. The rotation of the rotating column 42 will drive the fan-shaped plate 43 to rotate. Since the tooth 2 431 on the fan-shaped plate 43 is engaged with the tooth 1 211 on the extension bar 21, the fan-shaped plate 43 will drive the extension bar 21 to swing, and then the light baffle 2 will swing, thereby realizing the switching of the light baffle 2 between low beam and high beam. When high beam is needed, the light baffle 2 swings down, and at this time the light baffle 2 is inclined. When low beam is needed, the light baffle 2 swings up, and at this time the light baffle 2 is horizontal and blocks the light.

[0028] When it is low beam, the light baffle 2 is in a horizontal state, and the arc-shaped heat-conducting plate 51 and the heat-dissipating fins 52 on the light baffle 2 are in a separated state. At this time, the clips 511 on the arc-shaped heat-conducting plate 51 and the heat-dissipating fins 52 on the light baffle 2 will absorb the heat in the LED lens module, and the heat on the heat-dissipating fins 52 will be transferred to the light baffle 2, and then transferred to the support rod 1, and the clips 511 on the arc-shaped heat-conducting plate 51 will also absorb the heat in the LED lens module, and the heat will also be transferred to the support rod 1, and finally the support rod 1 will transfer the heat to the base frame 101, thereby accelerating the heat dissipation in the inner cavity of the LED lens module, and the copper tube 1 53 and the copper tube 2 54 can also accelerate the heat transfer on the arc-shaped heat-conducting plate 51, and can transfer the heat to the heat dissipation substrate 103 of the driver 102, thereby further accelerating the heat dissipation.

[0029] When the high beam is on, the light baffle 2 is in a downward swing state. At this time, the oblique insert strips 522 on the heat dissipation fins 52 on the light baffle 2 are tilted downward and inserted between the two side clips 511. At this time, the arc-shaped heat conductive plate 51 and the heat dissipation fins 52 on the light baffle 2 are in a connected state, and the heat transfer routes become more, which further accelerates the heat transfer, thereby accelerating the heat dissipation in the inner cavity of the LED lens module.

[0030] In addition, during the switching process between high and low beams, the rotating shaft 422 on the rotating column 42 rotates circumferentially, thereby driving the swing fan 423 on the rotating shaft 422 to swing. The swing fan 423 can fan the heat dissipation fins 52 on the arc-shaped heat conduction plate 51 and the light baffle 2, thereby accelerating the heat dissipation in the inner cavity of the LED lens module.

Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.

[0032] What has been described above is only a preferred specific implementation manner of the embodiments of the present application, but the protection scope of the present application is not limited thereto.
