Description

Technical Field

[0001] This invention relates to vehicle lights, and more specifically, to an optical component mounting structure. The invention also relates to a vehicle lighting device, a vehicle light, and a vehicle. Background Technology

[0002] Today's car headlights are showing a clear trend toward miniaturization, which requires the headlight module to have a more streamlined and integrated structure, and the arrangement of the various components in the headlight module to be more compact.

[0003] With the miniaturization and flattening of vehicle headlights, the market demand for small vehicle lighting devices is increasing. Small vehicle lighting devices generally refer to headlights where the longest of the three dimensions (length, width, and height) is less than or equal to 130mm, and the shorter of the length and width of the light-emitting surface of the lens or other light-emitting optical element is less than or equal to 20mm. Some small vehicle headlights require the longest of the three dimensions to be less than or equal to 110mm, and the shorter of the length and width of the light-emitting optical element to be less than or equal to 10mm. Small vehicle lighting devices require more compact components and higher positional precision between optical components.

[0004] Existing optical component mounting structures are no longer suitable for the current trend of miniaturization in automotive lights. Currently, there is no precise and reliable overall mounting structure for optical components of miniaturized lighting devices. The market urgently needs a simple, reliable, and highly accurate optical component mounting structure for miniaturized automotive lights. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an optical component mounting structure that has high positioning accuracy and is simple and reliable to install.

[0006] A further technical problem to be solved by the present invention is to provide a vehicle lighting device with a simple structure, high positioning accuracy of optical components, and reliable installation.

[0007] A further technical problem to be solved by the present invention is to provide a vehicle lamp that is small in size and has a precise and stable illumination beam pattern.

[0008] Another technical problem that this invention aims to solve is to provide a vehicle with small headlights that provide precise and stable illumination patterns.

[0009] To address the aforementioned technical problems, this invention provides an optical component mounting structure, including a primary optical element, a lens holder, a circuit board, and a heat sink. The primary optical element has mounting portions on both sides, each including a front mating portion at the front end and a rear mating portion at the rear end. A primary element limiting bracket is disposed within the lens holder. Two opposing C-shaped limiting structures are disposed on the heat sink. Two C-shaped positioning grooves are disposed on the circuit board. The circuit board is mounted on the heat sink via the engagement of the C-shaped positioning grooves and the C-shaped limiting structures. The rear end of the primary optical element is mounted on the heat sink via the engagement of the rear mating portion and the C-shaped limiting structures, and the front end is mounted on the lens holder via the engagement of the front mating portion and the primary element limiting bracket.

[0010] Preferably, there are two primary element limiting brackets, which are respectively disposed on both sides of the lens bracket. Relative to the position of the front mating part, the rear end of each primary element limiting bracket has a bracket groove, and the front mating part is mounted on the bracket groove. In this preferred embodiment, by engaging the bracket grooves on the two primary element limiting brackets with the front mating parts on the mounting parts on both sides of the primary optical element, a stable fit can be formed between the front end of the primary optical element and the lens bracket.

[0011] More preferably, the bracket groove includes an upper contact surface, an inner contact surface, and a lower contact surface; the front mating part includes an upper front mating surface, a front end mating surface, and a lower front mating surface. The upper front mating surface contacts the upper contact surface, the front end mating surface contacts the inner contact surface, and the lower front mating surface contacts the lower contact surface. This preferred technical solution achieves a stable fit and precise positioning between the front mating part and the bracket groove, resulting in higher stability and accuracy of the primary optical element's mounting on the lens bracket.

[0012] Furthermore, the front mating part also includes a side limiting block, which is located outside the primary element limiting frame and in contact with it. This preferred technical solution enables the front mating part to be positioned in the left-right direction, further improving the positioning accuracy of the primary optical element.

[0013] Preferably, the outer side of the C-shaped limiting structure includes an upper circuit board limiting surface, an outer circuit board limiting surface, and a lower circuit board limiting surface. The C-shaped positioning groove includes an upper part, a side part, and a lower part. The upper circuit board limiting surface contacts the upper sidewall of the upper part of the positioning groove, the outer circuit board limiting surface contacts the outer sidewall of the side part of the positioning groove, and the lower circuit board limiting surface contacts the lower sidewall of the lower part of the positioning groove. In this preferred embodiment, the circuit board is positioned by the three mating surfaces between the outer sidewall of the C-shaped positioning groove and the outer side of the C-shaped limiting structure, resulting in higher positioning stability and accuracy.

[0014] More preferably, the heat sink is provided with a circuit board contact surface, the C-shaped limiting structure is disposed within the circuit board contact surface, and the circuit board is in contact with the circuit board contact surface. In this preferred technical solution, the contact between the circuit board contact surface and the circuit board achieves two advantages: firstly, it forms a tight contact between the circuit board, the light source mounted on the circuit board, and the heat sink, improving the heat dissipation effect of the light source; secondly, it forms a backward positioning of the circuit board, improving the positioning accuracy of the circuit board and the light source mounted on the circuit board.

[0015] Preferably, the inner side of the C-shaped limiting structure includes an upper component limiting surface, an outer component limiting surface, and a lower component limiting surface. The rear mating portion includes a rear upper mating surface, a rear side mating surface, a rear lower mating surface, and a rear end mating surface. The rear upper mating surface contacts the upper component limiting surface, the rear side mating surface contacts the outer component limiting surface, the rear lower mating surface contacts the lower component limiting surface, and the rear end mating surface contacts the circuit board. This preferred technical solution achieves multi-directional positioning of the rear mating portion, resulting in a stable fit between the primary optical component and the heat sink, effectively improving the positioning accuracy between the rear end of the primary optical component and the circuit board and heat sink.

[0016] Preferably, the lens holder includes a lens mounting opening, and the lens is fixedly connected to the lens mounting opening. In this preferred embodiment, the lens's mounting position on the lens holder is fixed by the cooperation between the lens mounting opening and the lens, thereby defining the relative position between the lens, the primary optical element, and the light source, and ensuring the positioning accuracy between the lens and the primary optical element.

[0017] More preferably, the lens and the lens holder are integrally formed. This preferred technical solution further ensures the positioning accuracy and positional stability of the lens.

[0018] Preferably, the lens holder includes a positioning pin, and the circuit board has a circuit board positioning hole, in which the positioning pin is installed. This preferred technical solution ensures precise positioning between the lens holder and the circuit board, and the positioning between the circuit board and the heat sink ensures accurate fit between the lens and the primary optical components and the light source.

[0019] A second aspect of the present invention provides a vehicle lighting device that uses the optical component mounting structure provided in the first aspect of the present invention.

[0020] A third aspect of the present invention provides a vehicle lamp that uses the vehicle lamp lighting device provided in the second aspect of the present invention.

[0021] A fourth aspect of the present invention provides a vehicle that uses the headlights provided in the third aspect of the present invention.

[0022] Through the above technical solution, the optical component mounting structure of the present invention achieves precise positioning between the circuit board and the heat sink through the cooperation of two C-shaped positioning grooves and a C-shaped limiting structure; achieves precise positioning between the primary optical element and the heat sink through the cooperation between the rear mating part and the C-shaped limiting structure; and achieves precise positioning between the primary optical element and the lens holder through the cooperation between the front mating part and the primary element limiting frame. The optical component mounting structure of the present invention has a simple positioning structure, ensuring the installation and cooperation between smaller optical components, and providing higher positioning accuracy and stability for the light source and primary optical element. The inner and outer sides of the C-shaped limiting structure are respectively designed to cooperate and position with the primary optical element and the circuit board, improving the stress condition of the C-shaped limiting structure and further ensuring positioning stability and accuracy. The structure with multiple mating surfaces between the front mating part and the primary element limiting frame, and between the rear mating part and the C-shaped limiting structure and the circuit board, ensures the positioning accuracy and stability of the front and rear ends of the primary optical element. The fixed connection of the lens at the lens mounting port, and the cooperation between the lens holder and the positioning hole of the circuit board through the positioning pin, further ensure the positioning accuracy between the lens, the primary optical element, and the light source. The vehicle lighting device of the present invention has a simple positioning structure, allowing for a smaller size and higher positioning accuracy and stability of the optical components. Vehicles and lamps using the vehicle lighting device and lamp of the present invention also possess the aforementioned advantages.

The direction indicated by the directional term "front" is the light emission direction of the vehicle lighting device. The description of the orientation or positional relationship of the optical component mounting structure and the vehicle lighting device and its components of this invention is consistent with their actual installation orientation during use.

[0072] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "setting," or "connection" should be interpreted broadly. For example, the term "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0073] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention, and the scope of protection of the present invention is not limited to the specific embodiments described below.

[0074] like Figures 1 to 27 As shown, one embodiment of the optical component mounting structure of the present invention includes a primary optical element 1, a lens holder 2, a circuit board 3, and a heat sink 4. Mounting portions 11 are provided on both sides of the primary optical element 1. A front mating portion 12 is provided at the front end of the mounting portion 11, and the element is mounted on the lens holder 2 via the front mating portion 12. A rear mating portion 13 is provided at the rear end of the mounting portion 11, and the element is mounted on the heat sink 4 via the rear mating portion 13. A primary element limiting bracket 21 is provided inside the lens holder 2. The primary element limiting bracket 21, in cooperation with the front mating portion 12, fixes the front end of the primary optical element 1 onto the lens holder 2, forming a positioning installation between the front end of the primary optical element 1 and the lens holder 2. Two C-shaped limiting structures 41 are provided on the heat sink 4, with the openings of the two C-shaped limiting structures 41 facing each other. Two C-shaped positioning slots 31 are provided on the circuit board 3. The positions and orientations of the two C-shaped positioning slots 31 correspond to the C-shaped limiting structure 41, allowing the circuit board 3 to be installed on the heat sink 4 through the cooperation of the C-shaped positioning slots 31 and the C-shaped limiting structure 41, thus forming a mounting positioning between the circuit board 3 and the heat sink 4. At the same time, the rear end of the primary optical element 1 is installed on the heat sink 1 through the cooperation of the rear mating part 13 and the C-shaped limiting structure 41, forming a mounting positioning between the rear end of the primary optical element 1 and the heat sink 4. The mounting structure that forms a mounting positioning between the front and rear ends of the primary optical element 1 and the lens bracket 2 and the heat sink 4 respectively greatly improves the stability and positioning accuracy of the primary optical element 1. The mounting structure that uses two C-shaped limiting structures 41 to simultaneously position the primary optical element 1 and the circuit board 3 improves the mounting positioning accuracy between the circuit board 3 and the light source mounted on the circuit board 3 and the primary optical element 1.

[0075] In some embodiments of the optical component mounting structure of the present invention, such as Figure 6 , Figures 16 to 25 As shown, there are two primary element positioning brackets 21, which are respectively arranged on both sides of the lens mounting position on the lens holder 2. The positions of the two primary element positioning brackets 21 correspond to the positions of the front mating parts 12 on the primary optical element 1. Furthermore, the rear end of the primary element positioning bracket 21 is provided with a bracket groove 22, and the front end of the primary optical element 1 is mounted on the lens holder 2 through the engagement of the front mating parts 12 and the bracket groove 22. The bracket grooves 22 on the two primary element positioning brackets 21 can install and position the front end of the primary optical element 1 from both sides, resulting in higher installation accuracy and stability.

[0076] In some embodiments of the optical component mounting structure of the present invention, such as Figure 6 , Figures 16 to 25 As shown, the bracket slot 22 is a square bayonet slot. The upper part of the bayonet slot 22 is the upper contact surface 221, the inner side of the bayonet slot is the inner contact surface 222, and the lower part of the bayonet slot is the lower contact surface 223. The front mating part 12 is a square mating structure. The upper side of the mating structure is the upper front mating surface 121, the front side is the front end mating surface 122, and the lower side is the lower front mating surface 123. When the front mating part 12 is installed in the bracket slot 22, the upper front mating surface 121 contacts the upper contact surface 221, restricting the upward movement of the front end of the primary optical element 1; the front end mating surface 122 contacts the inner contact surface 222, restricting the forward movement of the primary optical element 1; and the lower front mating surface 123 contacts the lower contact surface 223, restricting the downward movement of the front end of the primary optical element 1. Together, these three elements form a precise and stable installation positioning between the front mating part 12 and the bracket slot 22. Small tooth-like structures can also be provided on the upper contact surface 221, the inner contact surface 222, and the lower contact surface 223 of the groove to improve the tightness and stability of the fit with the front mating part 12. The upper front mating surface 121, the front end mating surface 122, and the lower front mating surface 123 can also be provided with mating stripes or other mating structures to improve the stability of the fit.

[0077] As a specific embodiment of the optical component mounting structure of the present invention, such as Figures 17 to 26 As shown, each front mating part 12 has a side limiting block 124 on its upper and lower sides. When the front mating part 12 is installed in the bracket groove 22, the side limiting blocks 124 on both front mating parts 12 are located outside the primary component limiting frame 21 and are in contact with the primary component limiting frame 21. The inner side of each side limiting block 124 can also be provided with a positioning surface to improve positioning accuracy. Similarly, positioning surfaces can also be provided at the relative positions on the outer sides of the primary component limiting frame 21 portions above and below the bracket groove 22 to restrict the left and right movement of the front end of the primary optical element 1, or engaging surfaces can be provided at the relative positions on the outer sides of the primary component limiting frame 21 portions above and below the bracket groove 22 to simultaneously restrict the left and right movement of the front end of the primary optical element 1 and the front and back movement of the primary optical element 1, further improving the installation positioning accuracy and stability.

[0078] In some embodiments of the optical component mounting structure of the present invention, such as Figures 2 to 15 as well as Figure 27As shown, the outer side of the C-shaped limiting structure 41 is respectively provided with an upper circuit board limiting surface 411 on the upper side, an outer circuit board limiting surface 412 on the outer side, and a lower circuit board limiting surface 413 on the lower side. The C-shaped positioning groove 31 includes an upper positioning groove 311, a side positioning groove 312, and a lower positioning groove 313. When the circuit board 3 is installed on the C-shaped limiting structure 41, the upper circuit board limiting surface 411 contacts the upper side wall of the upper positioning groove 311 to restrict the circuit board 3 from moving downward relative to the C-shaped limiting structure 41; the outer circuit board limiting surface 412 contacts the outer side wall of the side positioning groove 312 to restrict the circuit board 3 from moving left and right relative to the C-shaped limiting structure 41; and the lower circuit board limiting surface 413 contacts the lower side wall of the lower positioning groove 313 to restrict the circuit board 3 from moving upward relative to the C-shaped limiting structure 41. This forms a three-sided positioning structure that matches the C-shaped positioning groove 31 with the outer side of the C-shaped limiting structure 41, while restricting the movement of the circuit board 3 and the C-shaped limiting structure 41 in the up, down, left, and right directions, thereby improving the installation positioning accuracy and stability between the circuit board 3 and the heat sink 4.

[0079] As a specific embodiment of the optical component mounting structure of the present invention, such as Figures 7 to 11 As shown, the heat sink 4 has a circuit board contact surface 42, and a C-shaped limiting structure 41 is disposed within the circuit board contact surface 42. When the circuit board 3 is mounted on the C-shaped limiting structure 41, the rear end of the circuit board 3 forms a tight contact with the circuit board contact surface 42. Through the tight contact between the circuit board 3 and the circuit board contact surface 42, on the one hand, the heat emitted by the light source mounted on the circuit board 3 can be better transferred to the heat sink 4, improving the heat dissipation effect of the light source. On the other hand, it can form a rearward positioning of the circuit board 3, improving the positioning accuracy of the circuit board 3 and the light source mounted on the circuit board 3.

[0080] In some embodiments of the optical component mounting structure of the present invention, such as Figures 2 to 15As shown, the inner side of the C-shaped limiting structure 41 on the heat sink 4 is respectively provided with an upper element limiting surface 414 on the upper side, an outer element limiting surface 415 on the outer side, and a lower element limiting surface 416 on the lower side. The upper side of the rear mating part 13 on the primary optical element 1 is set as a rear upper mating surface 131, the outer side is set as a rear side mating surface 132, the lower side is set as a rear lower mating surface 133, and the rear end surface is set as a rear end mating surface 134. When the rear mating part 13 is installed in the C-type limiting structure 41, the upper component limiting surface 414 limits the upper rear mating surface 131, restricting the upward movement of the rear end of the primary optical element 1; the outer component limiting surface 415 limits the rear side mating surface 132, restricting the left-right movement of the rear end of the primary optical element 1; the lower component limiting surface 416 limits the lower rear mating surface 133, restricting the downward movement of the rear end of the primary optical element 1; and the circuit board 3 limits the rear end mating surface 134, restricting the rearward movement of the primary optical element 1. In this way, multiple directions of limiting are achieved for the rear mating part 13, while simultaneously restricting the vertical, horizontal, and rearward movement of the primary optical element 1 and the C-type limiting structure 41, greatly improving the accuracy and stability of the rear end mounting and positioning of the primary optical element 1. Similarly, mating structures such as mating stripes can also be provided on the upper rear mating surface 131, the side rear mating surface 132, the lower rear mating surface 133, and the rear end mating surface 134 to improve mating accuracy and mating stability.

[0081] In some embodiments of the optical component mounting structure of the present invention, such as Figures 1 to 5 As shown, the front end of the lens bracket 2 is provided with a lens mounting port, and the lens 5 is fixedly connected to the lens mounting port. Specifically, the shape of the lens 5 can be freely designed according to the styling requirements of the vehicle headlight, and the shape of the lens mounting port is adapted to the mounting shape of the lens 5. The lens 5 can be fixed to the lens mounting port by means of connecting parts such as mounting cover plates, or by means of welding, gluing, etc., to form a mounting connection between the lens 5 and the lens bracket 2, ensuring the installation accuracy of the lens 5.

[0082] In one specific embodiment of the optical component mounting structure of the present invention, the lens 5 is integrally formed at the lens mounting opening, forming an integral structure of the lens 5 and the lens holder 2. Specifically, the lens 5 and the lens holder 2 can be integrally formed by two-color injection molding. The integrally formed structure of the lens 5 and the lens holder 2 ensures that the positioning accuracy of the lens 5 is only affected by the molding die, resulting in higher positioning accuracy for the lens 5.

[0083] In some embodiments of the optical component mounting structure of the present invention, such as Figures 16 to 27As shown, the lens holder 2 is provided with a positioning pin 23, the circuit board 3 is provided with a circuit board positioning hole 32, and the heat sink 4 is provided with a heat sink through hole 43. The lens holder 2, through the cooperation of the positioning pin 23 and the circuit board positioning hole 32, forms a precise positioning between the lens holder 2 and the circuit board 3. The heat sink through hole 43 forms a receiving space for the positioning pin 23, ensuring a higher positioning accuracy between the lens holder 2 and the circuit board 3, thereby ensuring the positioning accuracy between the light source, primary optical element 1, and lens 5 mounted on the circuit board 3. This positioning structure, together with the positioning structures between the primary optical element 1 and the primary element limiting bracket 21, the primary optical element 1 and the C-type limiting structure 41, and the circuit board 3 and the C-type limiting structure 41, forms a precise and stable positioning between the light source, the primary optical element 1, and the lens 5 from multiple aspects, improving the installation positioning accuracy of the optical components and the stability of the installation structure.

[0084] The mounting assembly of the vehicle lighting device of the present invention is as follows Figure 28 As shown, due to the use of the optical component mounting structure of any embodiment of the present invention, the mounting structure is simple, the vehicle lighting device can be designed to be smaller, and the optical component positioning accuracy is higher, and the installation positioning is more stable and reliable.

[0085] The vehicle headlights of the present invention, by using the vehicle headlight illumination device of the present invention, and the vehicles of the present invention, by using the vehicle headlights of the present invention, also have the above-mentioned advantages.

[0086] Additionally, it should be noted that although the optical component mounting structure of the present invention is designed for small vehicle lighting devices, the technical solution of the present invention is not only applicable to small vehicle lighting devices, but can also be used for larger vehicle lighting devices.
