DETAILED DESCRIPTION

[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figure 1-11 As shown, a dynamic headlight structure based on a cam-linkage mechanism includes a decorative ring 1, a headlight module 2 and a powered cam-linkage mechanism, wherein two decorative rings 1 are provided and arranged oppositely in an upper and lower position; the headlight module 2 is located at the rear side of the decorative ring 1; two powered cam-linkage mechanisms are provided and arranged oppositely on both sides of the two decorative rings 1, and the cam-linkage mechanism can drive the two decorative rings 1 to move toward or away from each other to cover or expose the headlight module 2 behind them.

[0037] In this embodiment, the vehicle light module 2 is a high and low beam module, namely the low beam and high beam of the vehicle, and the decorative ring 1 is a structure used only to block the high and low beam modules, forming a dynamic headlight effect of the high and low beam modules.

[0038] In addition, a lamp bead light source can also be set on the decorative ring 1 so that it can illuminate and realize the vehicle's signal light function, such as turn signal, brake light, etc., to form a dynamic lighting effect of switching between high and low beam modules and signal lights.

[0039] When the two decorative rings 1 are rotated toward each other, the high and low beam modules can be covered and the vehicle's signal light function can be used; when the two decorative rings 1 are rotated away from each other, the high and low beam modules can be exposed and the high beam or low beam can be used.

[0040] In order to facilitate the connection between the decorative ring 1 and the cam-link mechanism, swing rods 3 are respectively provided on both sides of the decorative ring 1, and the swing rods 3 on the same side of the two decorative rings 1 are connected to the same cam-link mechanism.

[0041] Any one or two cam-link mechanisms can drive the two decorative rings 1 to move toward or away from each other, thereby covering or revealing the rear lamp module 2 , thereby ensuring the synchronization of the movement of the two decorative rings 1 .

[0042] Among them, the decorative ring 1 is an arc-shaped plate structure with a convex front surface. Compared with a flat plate structure, this shape of the decorative ring 1 can completely cover the rear side headlight module 2 while reducing the space required for its rotation, thereby effectively reducing the space occupied by the dynamic lighting structure.

[0043] The swing rod 3 is located on both sides of the corresponding decorative ring 1 and away from the other decorative ring 1, that is, the swing rod 3 of the upper decorative ring 1 is located above it on both sides, and the swing rod 3 of the lower decorative ring 1 is located below it on both sides. This can avoid the swing rod 3 from interfering with the headlight module 2 during rotation.

[0044] In order to be able to drive the two decorative rings 1 to move synchronously through a cam-linkage mechanism, the cam-linkage mechanism includes a cam plate 4 and a connecting rod assembly connected to the cam plate 4. The cam drives the two decorative rings 1 to rotate toward or away from each other through the connecting rod assembly.

[0045] In order to achieve the two decorative rings 1 rotating toward or away from each other, the cam plate 4 is provided with a plurality of arc-shaped track grooves 6 spiraling in the same direction on the side facing the decorative ring 1 , and the connecting rod assembly is assembled in the corresponding spiral track grooves.

[0046] Specifically, four arc-shaped track grooves 6 are provided on the inner cam plate 4, which are connected to the two swing rods 3 on the same side of the two decorative rings 1 in groups of two. The two arc-shaped track grooves 6 located above are connected to the swing rod 3 of the upper decorative ring 1 through a connecting rod assembly, and the two arc-shaped track grooves 6 located below are connected to the swing rod 3 of the lower decorative ring 1 through a connecting rod assembly.

[0047] Seen from the right side, the arcuate track groove 6 on the left cam disc 4 spirals inward in a counterclockwise direction, while the track groove on the right cam disc 4 is symmetrical to the left cam disc 4 .

[0048] Preferably, an arc-shaped protrusion 22 corresponding to the arc-shaped track groove 6 is formed on the outer side of the cam plate 4, so that the depth of the arc-shaped track groove 6 can be ensured while reducing the thickness of the cam plate 4 to reduce the weight of the entire dynamic lighting structure.

[0049] Preferably, a plurality of cross-arranged reinforcing ribs 7 are provided on the outer side surface of the cam disc 4 to ensure the structural strength of the cam disc 4 .

[0050] In order to utilize the connecting rod assembly to realize the transmission of the cam plate 4 and the decorative ring 1, the connecting rod assembly includes a rocker arm 8 with a boss 9 provided on the outer side of one end, and a rotating shaft 10 connected to the inner side of the other end of the rocker arm 8. The connecting plate 11 at the inner end of the rotating shaft 10 is provided with an axle pin 12 rotatably connected to the corresponding swing rod 3. The boss 9 is installed in the corresponding arc trajectory groove 6 and can move in the arc trajectory groove 6.

[0051] The rocker arm 8 and the boss 9 form an L-shaped structure. The plate-shaped rocker arm 8 is arranged on the inner side of the cam disc 4 in parallel with the cam disc 4 , and the boss 9 fits in the corresponding arc-shaped track groove 6 .

[0052] The rotating shaft 10 and the connecting plate 11 at its inner end form an L-shaped structure. An axle pin 12 with a buckle 13 is provided at the end of the connecting plate 11 away from the rotating shaft 10. The connecting plate 11 is arranged on the outside of the swing rod 3 in a manner parallel to the cam disc 4, and the axle pin 12 is assembled in the corresponding assembly hole on the swing rod 3 to achieve rotational coordination between the swing rod 3 and the connecting plate 11. At the same time, the buckle 13 can also be used to fix it to prevent the axle pin 12 from falling out of the assembly hole.

[0053] When viewed from the right side, the cam disc 4 rotates counterclockwise, which can drive the two swinging rods 3 to rotate toward each other through the connecting rod assembly, so that the two decorative rings 1 cover the headlight module 2; on the contrary, when the cam disc 4 rotates clockwise, it can drive the two swinging rods 3 to rotate away from each other through the connecting rod assembly, so that the two decorative rings 1 reveal the headlight module 2.

[0054] In order to ensure the smoothness of the movement trajectory of the entire connecting rod assembly, when the boss 9 moves toward the inner end of the arc-shaped trajectory groove 6 where it is located, the pressure angle α formed by the boss 9 and the arc-shaped trajectory groove 6 is in the range of 35°-45°; when the boss 9 moves toward the outer end of the arc-shaped trajectory groove 6 where it is located, the pressure angle α formed by the boss 9 and the arc-shaped trajectory groove 6 is in the range of 70°-80°.

[0055] In order to facilitate the fixing of the cam disc 4 , the cam-linkage mechanism further includes a bracket 14 . The cam disc 4 is located outside the bracket 14 , and the link assembly passes through the bracket 14 and is connected to the corresponding swing rod 3 .

[0056] Specifically, the bracket 14 is provided with a through hole corresponding to the rotating shaft 10 , so that the rotating shaft 10 can pass through the through hole.

[0057] A support foot 15 is provided on the outer side of the bottom of the bracket 14 to ensure the stability of the bracket 14 .

[0058] In order to drive the cam plate 4 to rotate, the cam linkage mechanism further includes a motor 5 drivingly connected to the cam plate 4 .

[0059] The output shaft of the motor 5 is connected to the cam plate 4 to drive the cam plate 4 to rotate.

[0060] In order to facilitate the installation of the motor 5 , a base 16 mounted on the bracket 14 is provided on the outer side of the cam disc 4 , and the motor 5 is mounted on the outer side of the base 16 .

[0061] A center hole 18 is provided at the center of the base 16 , and the motor 5 is mounted on the outside of the base 16 . The core shaft 17 of the cam disc 4 passes through the center hole 18 and is connected to the motor 5 , so that the cam disc 4 is driven to rotate by the motor 5 .

[0062] Preferably, a positioning rod 19 is provided on the outside of the base 16, and a positioning hole 20 that cooperates with the positioning rod 19 is provided on the motor 5. When the motor 5 is installed on the outside of the base 16, the position can be positioned by the positioning rod 19 and the positioning hole 20.

[0063] In order to achieve the connection between the base 16 and the bracket 14 , the base 16 is an arc-shaped triangular structure with concave edges, and its three end points are mounted on the bracket 14 through fixing columns 21 .

[0064] The use of an arc-shaped triangle with an inwardly concave edge can ensure that the motor 5 is fixed while reducing the weight of the base 16 and the entire structure.

[0065] The fixing column 21 is mounted on the outer wall of the bracket 14 , and the three end points of the base 16 are mounted on the fixing column 21 by means of bolts.

[0066] Preferably, the outer side surface of the base 16 is provided with cross-arranged reinforcing ribs 7 to ensure the structural strength of the base 16 .

[0067] From the right side, as Figure 8-9 As shown, when the two motors 5 synchronously drive the cam disc 4 connected thereto to rotate clockwise, the two decorative rings 1 can be driven to move synchronously in opposite directions, thereby revealing the headlight module 2, that is, adjusting it to the display state; Figure 10-11 As shown, when the two motors 5 synchronously drive the cam disc 4 connected thereto to rotate counterclockwise, the two decorative rings 1 can be driven to move synchronously toward each other, thereby covering the headlight module 2, that is, adjusting it to a hidden state. The entire process is switched conveniently and smoothly to form a dynamic lighting effect.

[0068] Among them, when the vehicle is powered on, the motor 5 is controlled to operate to expose the headlight module 2, and when the vehicle is powered off, the motor 5 is controlled to operate to hide the headlight module 2. That is, the exposed and hidden states of the headlight module 2 can be set as needed.

[0069] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
