Description

Technical Field

[0001] The utility model relates to the technical field of vehicle structures and supporting components of projection lamp devices, in particular to a projection lamp assembly, and the utility model also relates to a vehicle applying the projection lamp assembly. Background Art

[0002] In the current field of vehicle lamp design, projection lamps are an important type of lamp in the overall vehicle structure design and subsequent operation. With the continuous progress of vehicle R & D technology and the increasing demand of vehicle occupants for the use of supporting lamps, the performance of projection lamps has increasingly attracted wide attention in the industry.

[0003] Especially in recent years, with the continuous improvement of relevant industry laws and regulations, the design requirements for vehicle projection signal lamps have also been continuously improved. In order to improve the recognition of projection symbols supporting vehicles, each manufacturer has also been continuously improving the design standards for the irradiation performance of projection signal lamps.

[0004] Generally, in the existing vehicle projection lamp designs, film (i.e., film) projection technology, MLA (microlens array) projection technology, and MEMS (microelectromechanical system) laser projection technology are often used. Among them, the module structures used in film projection technology and MLA projection technology have relatively small sizes, but their corresponding projection illuminances are relatively low, and the actual lighting effects are not very satisfactory; while MEMS laser projection technology can provide relatively high illuminance and relatively good lighting effects, but the sizes of its supporting modules are relatively large, and the corresponding component application costs are relatively high, increasing the actual application costs.

[0005] In addition, no matter which of the above projection technologies is used, their light source modules, radiator modules, and optical components all adopt an integrated overall lamp component structure directly encapsulated together, resulting in a relatively large size of the supporting radiator required for such projection devices in actual applications, a relatively large overall size of the components, and a relatively large supporting assembly space required for the entire projection device, causing many inconveniences to the layout of the corresponding lamp space of the vehicle and increasing the difficulty of the relevant structure design of the vehicle lamps.

[0006] In view of this, how to optimize the structural layout of the vehicle projection lamp to make the layout of the projection lamp in the vehicle body structure more flexible and convenient and improve its adaptability to the assembly space is an important technical problem that those skilled in the art need to solve at present. Summary of the Utility Model

[0007] The purpose of the present utility model is to provide a projection lamp assembly, which has good adaptability to the assembly space, can be arranged more flexibly in the vehicle body structure, so that the layout of the vehicle lamp space is more convenient, and the design difficulty of the lamp-related structures of the vehicle is correspondingly reduced. Another purpose of the present utility model is to provide a vehicle applying the above projection lamp assembly.

[0008] To solve the above technical problems, the present utility model provides a projection lamp assembly, including a light source assembly and a projection assembly, and further including an optical fiber assembly connected between the light source assembly and the projection assembly. The projection assembly includes a projection box and a projection lens module arranged inside the projection box and capable of projecting an optical signal into the external environment.

[0009] The light source assembly includes a heat dissipation box and a light source module arranged inside the heat dissipation box and capable of providing an optical signal for the projection lens module. A radiator cooperating with the light source module is further provided on the heat dissipation box. The heat dissipation box and the projection box are two mutually independent boxes.

[0010] The optical fiber assembly includes a transmission optical fiber connected between the light source module and the projection lens module and capable of transmitting an optical signal.

[0011] Preferably, a reference groove is recessed in the middle of the front end face of the radiator. The light source module is a lamp board fixedly arranged in the reference groove. A light guide shield is arranged on the front end face of the radiator and covers the reference groove in alignment. The light guide shield is snap-fitted with the radiator to form the heat dissipation box.

[0012] A collimating light guiding hole in alignment with the light emitting surface of the lamp board is provided through the middle of the light guide shield. The inner diameter of the collimating light guiding hole decreases from its inner hole opening to its outer hole opening. One end of the transmission optical fiber cooperating with the light source module is provided with a light guiding terminal adapted to be inserted into the collimating light guiding hole.

[0013] Preferably, a light guiding boss protrudes in the middle of the outer end face of the light guide shield. The collimating light guiding hole coaxially penetrates through the middle of the light guiding boss.

[0014] Preferably, a positioning groove is recessed in the edge part of the front end face of the radiator. The outer edge part of the light guide shield has a positioning plate protruding towards the radiator. The positioning plate is inserted into the positioning groove in alignment.

[0015] Preferably, the projection box includes a collimator with a collimation groove recessed in the middle of the front end face. The projection lens module is fixedly arranged in the collimation groove. A projection mask covering the collimation groove in alignment is arranged on the front end face of the collimator. The projection mask is snap-fitted with the collimator to form the projection box. The middle of the projection mask has a projection hole for the light signal to pass through.

[0016] A light-shielding sheet adapted to the projection lens module is further arranged in the collimation groove. One end of the transmission optical fiber that cooperates with the projection lens module is provided with a light-sending terminal adapted to be inserted into the collimator.

[0017] Preferably, a projection boss protrudes from the middle of the outer end face of the projection mask. The inside of the projection boss has a positioning cavity for the outer end of the projection lens module to be inserted in alignment. The projection hole coaxially penetrates through the middle of the projection boss and communicates with the positioning cavity.

[0018] Preferably, the optical fiber assembly further includes two mounting chucks, which are respectively arranged at both ends of the transmission optical fiber. One mounting chuck can be detachably connected to the projection box, and the other mounting chuck can be detachably connected to the heat dissipation box.

[0019] The present utility model further provides a vehicle, including a vehicle body and a projection lamp assembly located on the vehicle body. The projection lamp assembly is the projection lamp assembly as described in any one of the above.

[0020] Preferably, the vehicle body includes a sheet metal part, and the light source assembly is installed on the sheet metal part.

[0021] Preferably, a heat-conducting gasket in contact with the radiator is further arranged on the sheet metal part.

[0022] Compared with the above-mentioned background art, in the process of assembling and operating the projection lamp assembly provided by the present utility model, since the heat dissipation box and the projection box are two independent different boxes respectively, when actually assembling and arranging, the light source assembly with the heat dissipation box as the main structure and the projection assembly with the projection box as the main structure can be arranged at different positions on the vehicle body. For example, the light source assembly can be arranged on metal structural components such as the sheet metal parts of the vehicle body that are convenient for heat dissipation, so as to further optimize the heat dissipation effect of the radiator on the light source module; at the same time, the projection assembly can be correspondingly arranged at the edge positions such as the bumper, anti-collision strip, air intake grille or fender of the vehicle body, so as to optimize the projection imaging effect of the light projected outward by the projection lens module, and further optimize the irradiation performance of the projection lamp assembly. In addition, due to the adoption of a split layout of the projection assembly and the light source assembly, the assembly space required for a single component of the projection lamp assembly can be greatly reduced, so that the light source assembly can be arranged at a more concealed and heat-dissipating position on the vehicle body. Thus, not only can the utilization rate of the assembly space of the vehicle body be effectively improved, but also the adaptability of the working conditions of the projection lamp assembly can be further optimized, and the projection lamp assembly can be flexibly arranged at the corresponding position on the vehicle body according to the structural requirements of the vehicle body, improving the convenience of the vehicle body structure arrangement and correspondingly reducing the design difficulty of the vehicle body and the related structures of the vehicle lamp. On this basis, by using the optical fiber assembly as the optical signal conduction mechanism between the light source assembly and the projection assembly, the efficient and stable transmission of the optical signal can be effectively guaranteed, the signal intensity loss during the transmission process can be reduced, and the optical signal intensity delivered to the projection assembly can be ensured, so as to ensure that the projection illumination effect of the projection lamp assembly can meet the corresponding working condition requirements.

[0023] In another preferred solution of the present utility model, a reference groove is recessed in the middle of the front end face of the radiator, the light source module is a lamp board fixedly arranged in the reference groove, a light guide shield is arranged on the front end face of the radiator and covers the reference groove in a position-aligned manner, and the light guide shield is snap-fitted with the radiator to form the heat dissipation box; a collimating light guiding hole that is position-aligned with the light emitting surface of the lamp board is penetrated through the middle of the light guide shield, and the inner diameter of the collimating light guiding hole decreases from its inner hole opening to its outer hole opening. One end of the transmission optical fiber that cooperates with the light source module is provided with a light guiding terminal that is inserted and adapted to the collimating light guiding hole. The variable diameter structure with a gradually decreasing inner diameter from the inner hole opening to the outer hole opening helps to further optimize the effect of gathering and guiding the optical signal emitted from the lamp board by the collimating light guiding hole, so that the intensity of the optical signal sent into the transmission optical fiber through the cooperation of the collimating light guiding hole and the light guiding terminal can meet the projection operation requirements of the downstream projection lens module, thereby avoiding the situation of reduced projection light intensity of the projection lamp assembly that may occur due to the adoption of a split layout structure, and further ensuring the projection illumination effect of the projection lamp assembly.

[0039] Please refer to Figures 1 to 4 。

[0040] In the specific embodiment, the projection lamp assembly provided by the present utility model includes a light source assembly 11 and a projection assembly 12, and further includes an optical fiber assembly 13 connected between the light source assembly 11 and the projection assembly 12. The projection assembly 12 includes a projection box 121 and a projection lens module 122 arranged inside the projection box 121 and capable of projecting an optical signal into the external environment.

[0041] The light source assembly 11 includes a heat dissipation box 111 and a light source module 112 arranged inside the heat dissipation box 111 and capable of providing an optical signal for the projection lens module 122. A radiator 13 cooperating with the light source module 112 is further provided on the heat dissipation box 111. The heat dissipation box 111 and the projection box 121 are two independent boxes arranged separately.

[0042] The optical fiber assembly 13 includes a transmission optical fiber 131 connected between the light source module 112 and the projection lens module 122 and capable of transmitting optical signals.

[0043] During the assembly and operation process, since the heat dissipation box 111 and the projection box 121 are two independent different boxes respectively, when actually assembling and arranging, the light source assembly 11 with the heat dissipation box 111 as the main structure and the projection assembly 12 with the projection box 121 as the main structure can be arranged at different positions on the vehicle body respectively.

[0044] For example, the light source assembly 11 can be arranged on metal structural components such as the sheet metal part 20 of the vehicle body that are convenient for heat dissipation, so as to further optimize the heat dissipation effect of the radiator 13 on the light source module 112. At the same time, the projection assembly 12 can be correspondingly arranged at the edge positions such as the bumper, anti-collision strip, intake grille or fender of the vehicle body, so as to optimize the projection imaging effect of the light projected outward by the projection lens module 122 and further optimize the irradiation performance of the projection lamp assembly.

[0045] Of course, the light source assembly 11 can also be arranged on other structural components of the vehicle body that have a certain structural strength and support ability, or the light source assembly 11 can be arranged in more concealed gaps or chambers inside the vehicle body. In short, due to the adoption of the combined structure of the separate arrangement of the light source assembly 11 and the projection assembly 12, and the use of the optical fiber assembly 13 to effectively ensure the stable and efficient transmission of optical signals between the light source assembly 11 and the projection assembly 12, in actual application, the arrangement positions of the light source assembly 11 and the projection assembly 12 can be flexibly selected according to the actual structural conditions and design requirements of the vehicle body, in order to achieve the best component heat dissipation and projection lighting effects, thereby correspondingly improving the working performance of the vehicle's headlight system.

[0046] It is not difficult to understand that due to the adoption of the separate arrangement of the projection assembly 12 and the light source assembly 11, the assembly space required for a single component of the projection lamp assembly can be greatly reduced, so that the light source assembly 11 can be arranged at a more concealed and heat dissipation-convenient position on the vehicle body. Thus, not only can the utilization rate of the assembly space of the vehicle body be effectively improved, but also the adaptability of the working conditions of the projection lamp assembly can be further optimized, and the projection lamp assembly can be flexibly arranged at the corresponding position on the vehicle body according to the structural requirements of the vehicle body, improving the convenience of the vehicle body structure arrangement and correspondingly reducing the design difficulty of the vehicle body and related headlight structures. On this basis, using the optical fiber assembly 13 as the optical signal conduction mechanism between the light source assembly 11 and the projection assembly 12 can effectively ensure the efficient and stable transmission of optical signals, reduce the signal intensity loss during the transmission process, ensure the optical signal intensity delivered to the projection assembly 12, and thus ensure that the projection lighting effect of the projection lamp assembly can meet the corresponding working condition requirements.

[0047] Generally, the light source assembly 11 can be correspondingly mounted to the sheet metal part 20 of the vehicle body or other structural members with a certain structural strength and supporting capacity by screws. It can also be snap-fitted and fixed to the corresponding position of the vehicle body by snaps, or can be adhesively fixed to the corresponding position of the vehicle body by adhesives such as glue, so as to meet the installation requirements of the light source assembly 11 and ensure its structural strength and reliability.

[0048] Correspondingly, the projection assembly 12 can also be correspondingly mounted to the corresponding position of the vehicle body by the above-mentioned screw connection, snap connection or glue bonding methods. In short, the installation and fixing methods of the light source assembly 11 and the projection assembly 12 on the vehicle body can be flexibly selected and adjusted according to the specific working conditions. In principle, as long as the reliable installation and fixing of the light source assembly 11 and the projection assembly 12 can be ensured and the actual application needs of the projection lamp assembly are met, it is acceptable.

[0049] Specifically, a reference groove 114 is recessed in the middle of the front end face of the radiator 13. The light source module 112 is a lamp board fixedly arranged in the reference groove 114. A light guide shield 115 is arranged on the front end face of the radiator 13 and is positioned to cover the reference groove 114. The light guide shield 115 is snap-fitted with the radiator 13 to form a heat dissipation box 111. A collimating light guiding hole 116 that is in alignment and cooperation with the light emitting surface of the lamp board is penetrated through the middle of the light guide shield 115. The inner diameter of the collimating light guiding hole 116 decreases from its inner hole opening to its outer hole opening. One end of the transmission optical fiber 131 that cooperates with the light source module 112 is provided with a light guiding terminal 132 that is adaptively inserted into the collimating light guiding hole 116. The variable diameter structure with a gradually decreasing inner diameter from the inner hole opening to the outer hole opening helps to further optimize the effect of gathering and guiding the light signal emitted from the lamp board by the collimating light guiding hole 116, so that the intensity of the light signal fed into the transmission optical fiber 131 through the cooperation of the collimating light guiding hole 116 and the light guiding terminal 132 can meet the projection operation requirements of the downstream projection lens module 122, thereby avoiding the situation of reduced projection light intensity of the projection lamp assembly that may occur due to the adoption of a split layout structure, and further ensuring the projection lighting effect of the projection lamp assembly.

[0050] Of course, in addition to the lamp board mentioned above, the light source module 112 can also be a lamp bead or other light emitting devices. Its light source type can be an LED light source or a halogen light source. The structural style and light source type of the light source module 112 can also be flexibly selected and adjusted according to the specific working conditions and design requirements of the vehicle. In principle, as long as the actual application needs of the projection lamp assembly can be met, it is acceptable.

[0051] On this basis, a light guiding boss 117 is convexly provided in the middle of the outer end face of the light guiding cover 115, and the collimating light guiding hole 116 coaxially penetrates through the middle of the light guiding boss 117. The light guiding boss 117 can further increase the axial effective extension length of the collimating light guiding hole 116, thereby further optimizing the guiding and condensing effects of the collimating light guiding hole 116 on the optical signal, so that the transmission of the optical signal is more stable and efficient, and the projection light effect of the projection lamp assembly is further optimized.

[0052] In addition, a positioning groove 118 is recessed in the edge part of the front end face of the radiator 13, and the outer edge part of the light guiding cover 115 has a positioning plate 119 protruding towards the radiator 13. The positioning plate 119 is inserted into the positioning groove 118 in a position-aligned manner. By inserting the positioning plate 119 into the positioning groove 118 in a position-aligned manner, a reliable limit is formed between the light guiding cover 115 and the radiator 13 after buckling along the direction perpendicular to the main extension plane of the light guiding cover 115, so as to further improve the assembly strength between the radiator 13 and the light guiding cover 115, and correspondingly improve the overall structural stability of the heat dissipation box 111.

[0053] On the other hand, the projection box 121 includes a collimator 123 with a collimating groove 124 recessed in the middle of the front end face. The projection lens module 122 is fixedly arranged in the collimating groove 124. A projection mask 125 covering the collimating groove 124 in a position-aligned manner is arranged on the front end face of the collimator 123. The projection mask 125 is buckled with the collimator 123 in a position-aligned manner to form the projection box 121. A projection hole 126 for the optical signal to pass through is provided in the middle of the projection mask 125.

[0054] A light shielding sheet 127 adapted to the projection lens module 122 is further arranged in the collimating groove 124. One end of the transmission optical fiber 131 cooperating with the projection lens module 122 is provided with a light sending terminal 133 adapted to be inserted into the collimator 123.

[0055] As a relatively conventional optical signal auxiliary guiding component in the industry, the light shielding sheet 127 can effectively ensure the traceability and signal intensity of the optical signal propagation, thereby further optimizing the projection light effect of the projection lamp assembly. The collimator 123 can further improve the collimating processing effect of the optical signal to ensure the propagation intensity and traceability of the optical signal.

[0056] More specifically, a projection boss 128 is protrudingly provided in the middle of the outer end surface of the projection mask 125. A positioning cavity 129 for the outer end portion of the projection lens module 122 to be inserted in alignment is provided inside the projection boss 128. The projection hole 126 coaxially penetrates through the middle of the projection boss 128 and communicates with the positioning cavity 129. By inserting the projection lens module 122 in alignment into the positioning cavity 129, the assembly structure stability of the projection lens module 122 can be effectively ensured, and thereby the traceability and stability of the optical signal emitted by it can be correspondingly improved, so that the projection light effect of the projection lamp assembly is further optimized.

[0057] In addition, the optical fiber assembly 13 further includes two mounting chucks 134, which are respectively arranged at both ends of the transmission optical fiber 131. One of the mounting chucks 134 can be detachably connected to the projection box 121, and the other mounting chuck 134 can be detachably connected to the heat dissipation box 111. The mounting chuck 134 can effectively ensure the connection stability and assembly strength between the transmission optical fiber 131 and the projection box 121 and the heat dissipation box 111. In practical applications, the mounting chuck 134 and the projection box 121 and the heat dissipation box 111 can be assembled by clamping, or can be fastened by screws, or can be adhesively assembled by adhesives such as glue. The staff can flexibly select and adjust the assembly form between the mounting chuck 134 and the corresponding box body components according to the specific working conditions. In principle, as long as the assembly stability between the optical fiber assembly 13 and the light source assembly 11 and the projection assembly 12 can be ensured and the actual application requirements of the projection lamp assembly can be met.

[0058] In a specific embodiment, the vehicle provided by the present invention includes a vehicle body and a projection lamp assembly located on the vehicle body, and the projection lamp assembly is the projection lamp assembly as described above. The projection lamp assembly of this vehicle has good adaptability to the assembly space, can be arranged more flexibly in the vehicle main structure, so that the layout of the vehicle lamp space is more convenient, and the design difficulty of the vehicle lamp related structures is correspondingly reduced.

[0059] Furthermore, the vehicle body includes a sheet metal part 20, and the light source assembly 11 is installed on the sheet metal part 20. The sheet metal part 20 is a metal part. By arranging the light source assembly 11 on the sheet metal part 20, the heat dissipation performance of the radiator 13 in the light source assembly 11 can be utilized, and the heat dissipated from the radiator 13 can be conducted and diffused more quickly and efficiently, so as to further improve the working efficiency of the radiator 13, optimize its heat dissipation and cooling effect on the light source module 112, and ensure that the light source module 112 is at an appropriate working temperature.

[0060] On this basis, a heat-conducting gasket in contact and cooperation with the radiator 13 is further provided on the sheet metal part 20. This heat-conducting gasket usually also uses a metal gasket to further improve the heat transfer efficiency between the radiator 13 and the sheet metal part 20, and this heat-conducting gasket can provide a certain structural buffer for the assembly structure between the radiator 13 and the sheet metal part 20, so as to prevent the main structure of the sheet metal part 20 from being worn or structurally interfered due to the direct contact between the radiator 13 and the sheet metal part 20, thereby correspondingly ensuring the main structure strength of the sheet metal part 20.

[0061] Of course, the heat-conducting gasket can also be made of other heat-conducting materials so as to efficiently conduct heat from the radiator 13 to the sheet metal part 20. In practical applications, screw assembly or bonding assembly is generally selected as the specific assembly form between the light source assembly 11 and the sheet metal part 20. Correspondingly, the heat-conducting gasket can be assembled to the sheet metal part 20 together with screws or adhesives to ensure the assembly structure consistency and component integration degree between the heat-conducting gasket, the radiator 13 and the sheet metal part 20, and improve the assembly stability between the projection lamp assembly and the body main structure.

[0062] In summary, in the projection lamp assembly provided by the present utility model, during the assembly and operation process, since the heat dissipation box and the projection box are two independent different boxes respectively, when actually arranging the assembly, the light source assembly with the heat dissipation box as the main structure and the projection assembly with the projection box as the main structure can be respectively arranged at different positions on the vehicle body. For example, the light source assembly can be arranged on metal structural parts such as the sheet metal part of the vehicle body that are convenient for heat dissipation to further optimize the heat dissipation effect of the radiator on the light source module; at the same time, the projection assembly can be correspondingly arranged at edge positions such as the bumper, anti-collision strip, air intake grille or fender of the vehicle body to optimize the projection imaging effect of the light projected outward by the projection lens module and further optimize the irradiation performance of the projection lamp assembly. In addition, due to the adoption of the split arrangement of the projection assembly and the light source assembly, the assembly space required for a single component of the projection lamp assembly can be greatly reduced, so that the light source assembly can be arranged at a more concealed and heat-dissipating position on the vehicle body. Thus, not only can the utilization rate of the assembly space of the vehicle body be effectively improved, but also the adaptability of the working condition environment of the projection lamp assembly can be further optimized, and the projection lamp assembly can be flexibly arranged at the corresponding position on the vehicle body according to the structural requirements of the vehicle body, improving the convenience of the vehicle body structure arrangement and correspondingly reducing the design difficulty of the vehicle body and related structures of the vehicle lamp. On this basis, using the optical fiber assembly as the optical signal conduction mechanism between the light source assembly and the projection assembly can effectively ensure the efficient and stable transmission of optical signals, reduce the signal intensity loss during the transmission process, ensure the optical signal intensity delivered to the projection assembly, and thus ensure that the projection illumination effect of the projection lamp assembly can meet the corresponding working condition requirements.

[0063] The present utility model also provides a vehicle, and the projection lamp assembly thereof has good adaptability to the assembly space, can be arranged more flexibly in the vehicle body structure, so that the layout of the vehicle lamp space is more convenient, and the design difficulty of the lamp-related structures of the vehicle is correspondingly reduced.
