Description

Technical Field

[0001] The utility model relates to the technical field of automobile lighting devices, in particular to an automobile lamp module. Background Art

[0002] In the dimming structure of an automotive lighting module, a screw generally drives an optical element (such as a reflector) to rotate, thereby changing the angle between the optical element and the light source, thereby adjusting the angle of the light emitted by the light source to achieve the dimming purpose.

[0003] In the prior art, for example, in a structure for changing the angle of light irradiation by adjusting the angle of the reflector, two rotating shafts (protruding from the reflector body) for its rotation are generally provided on both sides of the reflector, and the rotating shafts are placed in a rotating groove in the housing of the headlight module to enable the reflector to rotate relative to the housing / light source. However, due to the limitations of the structure and space in the housing, the structure and shape of the reflector are also limited. For example, when two rotating shafts (and the auxiliary connecting parts of the rotating shafts) are formed on the reflector body, on the one hand, the unevenness of the structure is not conducive to product molding (such as product demoulding). On the other hand, although the integrated structure of the reflector and the two rotating shafts (and the auxiliary connecting parts of the rotating shafts) results in fewer product accessories, if part of the structure is damaged during the installation of the reflector, the entire accessory will be damaged. Utility Model Content

[0004] The purpose of the utility model is to provide an automobile headlight module, which is connected to the reflector through a transmission plate, and a rotating shaft is formed on both sides of the two. The rotating shaft is rotatably arranged in a rotation positioning hole. The transmission plate plays both a connecting and a transmission role, simplifying the structure while ensuring a stable connection. The reflector can also be rotated accurately, and the housing assembly also has a simple installation method and a stable installation effect.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: an automobile lamp module, comprising:

[0008] An optical assembly, comprising a reflector, an inner lens and an outer lens arranged in sequence from the inside out, wherein the reflector is connected to the inner lens and has a first rotating shaft on one side and a socket on the other side, and the outer lens is arranged on the housing assembly.

[0009] The dimming component includes a screw and a transmission plate. The screw is rotatably arranged on the housing component. One end of the transmission plate is provided with a plug plate, the other end is provided with a toothed belt, and the middle part is provided with a second rotating shaft.

[0010] The inserting plate is inserted into the socket, the first rotating shaft and the second rotating shaft are respectively embedded in a pair of the rotation positioning holes, and the toothed belt is engaged with the screw.

[0011] As a further optimization, the socket is provided with a bayonet connected thereto, and the plug plate is provided with a card block, which is embedded in the bayonet, thereby preventing the plug plate from detaching from the socket and improving the connection stability of the transmission plate.

[0012] As a further optimization, the socket and the bayonet are formed on the reflector.

[0013] As a further optimization, a C-shaped opening is provided on the transmission plate next to the second rotating shaft and passes through its body, which facilitates deformation at the position of the second rotating shaft and makes it easy to embed the second rotating shaft into the rotation positioning hole through deformation.

The end of the heat sink extends into the through hole and the limiting plate is misaligned with the side hole by rotation; a positioning platform is provided on the heat sink, and the positioning platform and the limiting plate respectively abut against the inner and outer sides of the shell body to fix the heat sink.

[0017] As a further optimization, a baffle is provided in the shell body, and the limiting plate abuts against the baffle.

[0018] As a further optimization, the heat sink is made of copper or aluminum, which can have an excellent heat dissipation effect.

[0019] As a further optimization, the shell assembly also includes a positioning member, which includes a mounting plate and a support plate arranged on the mounting plate. The shell body is provided with a plug post, the mounting plate is arranged on the plug post, and a pair of the support plates abut against the side walls of the heat sink, which can prevent the heat sink from rotating relative to the shell body.

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] like Figures 1 to 4As shown, an automobile lamp module includes a housing component 1A, an optical component 2A, a light source component 3A and a dimming component 4A. Rotation positioning holes 11 are respectively provided on opposite sides of the housing component 1A. The optical component 2A includes a reflector 21, an inner lens 22 and an outer lens 23 arranged in sequence from the inside to the outside. The reflector 21 is connected to the inner lens 22. The two can be connected by a snap-fit ​​structure or a locking structure. A first rotating shaft 211 is provided on one side of the two, and a socket 2121 is provided on the other side (i.e., the position between the reflector 21 and the inner lens 22 after the two are connected). Preferably, the first rotating shaft 211 and the socket 2121 are respectively formed on the opposite sides of the reflector 21. On both sides, the outer lens 23 is arranged on the shell assembly 1A, the light source assembly 3A includes a control board 31 arranged on the shell assembly 1A, and a light source 32 arranged on the control board 31, the dimming assembly 4A includes a transmission plate 41 and a screw 42, the screw 42 is rotatably arranged on the shell assembly 1A, one end of the transmission plate 41 is provided with a plug plate 4111, and the two are in a vertical structure, the other end of the transmission plate 41 is provided with a toothed belt 413, and a second rotating shaft 412 is provided in the middle, the plug plate 4111 is inserted into the socket 2121, the first rotating shaft 211 and the second rotating shaft 412 are respectively embedded in a pair of rotation positioning holes 11, and the toothed belt 413 is engaged with the screw 42.

[0031] In the present invention, the transmission plate 41 cooperates with the reflector 21, and the transmission plate 41 and the reflector 21 are fixedly connected after the plug plate 4111 is inserted into the socket 2121, and the two form an integral structure. The first rotating shaft 211 and the second rotating shaft 412 on the two are rotatably set in a pair of rotation positioning holes 211 on the housing assembly 1A, so as to realize the relative rotation of the reflector 21 in the housing assembly 1A. By rotating the screw 42, with the help of the external thread 421 on the screw 42 and the cooperation with the toothed belt 413, and the positioning of the second rotating shaft 412 set in the rotation positioning hole 11, the transmission plate 41 can be realized to swing up and down, thereby driving the reflector 21 to rotate relative to the light source 32, so that the angle of the light emitted by the light source 32 changes after being refracted by the reflector 21, thereby achieving the purpose of adjusting the angle of the light.

[0032] The utility model forms a rotating shaft on both sides of the two after the transmission plate 41 is connected to the reflector 21. The rotating shaft is rotatably set in the rotation positioning hole 11. The transmission plate 41 and the screw 42 cooperate to realize the swing of the transmission plate 41 to drive the angle of the reflector 21 to change. The transmission plate 41 plays a connecting and transmission role at the same time, which not only simplifies the structure, but also facilitates the connection of related structures and ensures the stability of the connection. In addition, the reflector 21 can also rotate accurately after being driven.

[0033] Combine Figure 5As shown, in order to ensure a more stable connection between the plug board 4111 and the socket 2121 of the reflector 21, a bayonet 2122 connected to the socket 2121 is provided on the reflector 21, and a clamping block 4112 is provided on the plug board 4111, which is embedded in the bayonet 2122, so that the plug board 4111 is not easily separated from the socket 2121.

[0034] To ensure that the first rotating shaft 211 and the second rotating shaft 412 can be arranged in the rotation positioning hole 11, the first rotating shaft 211 and the second rotating shaft 412 are first arranged not in the same plane as the main structure of the reflector 21. The first rotating shaft 211 and the second rotating shaft 412 are located at both ends and can be deformed relative to the main structure of the reflector 21 after being squeezed so as to be embedded in the rotation positioning hole 11 and then reset. In addition, a C-shaped opening 410 that passes through the transmission plate 41 can be provided on the transmission plate 41 next to the second rotating shaft 412. The existence of the C-shaped opening 410 makes it easier for the second rotating shaft 412 to be deformed, and it is easier to embed the second rotating shaft 412 in the rotation positioning hole 11 where it is located.

[0035] In the present invention, the shell assembly 1A includes at least a shell body 10 and a heat sink 50. The shell body 10 is provided with a through hole 100. The heat sink 50 can be made of copper or aluminum with excellent thermal conductivity. The heat sink 50 has at least one contact end with a surface structure and a heat sink fin arranged on one side of the contact end. The contact end of the heat sink 50 extends into the through hole 100 and abuts against the control board 31. Heat conduction is carried out through the contact between the contact end and the control board 31, and heat conduction between the heat sink fin and the air after the heat sink extends out of the shell body 10 to achieve the cooling effect on the optical component 3A, so as to ensure the stability of the working state of the optical component 3A and improve its service life.

[0036] At least one side hole 100′ connected to the through hole 100 is provided on the shell body 10 next to the through hole 100, and at least one limit plate 51 is provided on the heat sink 50. The limit plate 51 on the heat sink 50 passes through the through hole 100 through the existing side hole 100′, and after rotation, the limit plate 51 is misaligned with the side hole 100′, and a positioning platform is provided on the heat sink 50 (for example, the outer diameter of the heat sink is larger than the outer diameter of the contact end, that is, the part of the heat sink protruding from the contact end forms a positioning platform), and the positioning platform and the limit plate 51 respectively abut the inner and outer side walls of the shell body 10 to fix the heat sink 50.

[0037] In addition, a baffle 12 is provided in the shell body 10 , and after the heat sink 50 is rotated, the limiting plate 51 thereof abuts against the baffle 12 , thereby ensuring that the heat sink 50 is installed in place.

[0038] Furthermore, to prevent the heat sink 50 from rotating on the housing body 10, the housing assembly 1A further includes a positioning member 60. The positioning member 60 includes a mounting plate 61 and a pair of support plates 62 disposed on the mounting plate 61. The housing body 10 is provided with a plug post 13. The mounting plate 61 is mounted on the plug post 13 through its socket, and the pair of support plates 62 abut against the side walls of the heat sink 50. After the heat sink 50 is installed on the housing body 10, the positioning connection between the mounting plate 61 and the plug post 13 causes the pair of support plates 62 to abut against the pair of cooling fins on the heat sink 50 at two locations, thereby preventing the heat sink 50 from rotating and ensuring the installation stability of the heat sink 50.

[0039] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
