DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] Please refer to Figure 3-10 As shown, the present embodiment provides a thick-walled lamp part 100, which includes: a lens 110, a substrate 111 and an LED lamp bead 112, wherein the lens 110 is used to reflect and refract the light 100a to improve the light output intensity of the light 100a. In the present embodiment, the lens 110 has a light inlet 11a, which is used to receive the light 100a from the LED lamp bead 112 and process the light 100a through the internal structure; further, in the present embodiment, the side of the substrate 111 facing the lens 110 is designed to be a plane, and the LED lamp bead 112 is provided with a light inlet 11a. 12 is located on the side of the substrate 111 facing the lens 110, and the LED lamp bead 112 is electrically connected to the substrate 111. By connecting the substrate 111, the current can be transmitted to the LED lamp bead 112 through the substrate 111, making it emit light; further, the LED lamp bead 112 can be displaced relative to the lens 110 so as to be close to or away from the lens 110, and can be displaced to align with the light entrance 11a, so that the light 100a of the LED lamp bead 112 is concentrated into the light entrance 11a and emitted outward from the other side of the lens 110.

[0038] It is understandable that when the shape of the headlight housing is a special-shaped or curved structure, the traditional thick-walled component design often adopts a stepped structure to adapt, which requires the PCB to be designed to match the structure of the thick-walled component. The thick-walled component is usually designed in two structures, one is as follows: Figure 1 As shown, the PCBA is made by bonding the stepped aluminum plate with the FPC soft plate, and the PCBA is also made by combining the FPC with the stepped aluminum plate. Figure 2 As shown, make all TIR focusing cups flat ( Figure 2 ) in order to arrange LEDs, and of these two methods, the former method increases the design complexity of the PCB, resulting in increased manufacturing costs, while the latter method will cause the thick-walled lens 110 to be too high and the product weight to be too heavy, thereby resulting in expensive material costs.

[0039] The key to the design of this embodiment is that the position of the LED lamp beads 112 can be adjusted, allowing them to be close to or away from the lens 110. When the LED lamp beads 112 are adjusted to a position close to the lens 110, they can be more accurately aligned with the light inlet 11a of the lens 110, so that the emitted light 100a enters the lens 110 more concentratedly. After being processed by the internal structure of the lens 110, these light rays 100a are emitted from the other side of the lens 110; it can be understood that by designing that the position of the LED lamp beads 112 can be adjusted, the substrate 111 can be designed in a planar manner, avoiding the need for the substrate 111 to match the curved surface structure of the lens 110 and thus be designed as a stepped structure, or requiring the lens 110 to match the lamp beads so that the light inlet 11a close to the substrate 111 is designed as a flush structure, both of which increase the design and production costs; in addition, the simplicity and reliability of the thick-walled part 100 of the car lamp are also improved. Through such a structural setting, the entire car lamp system can flexibly adjust the position of the light source in the lamp housing of different models of car lamps, so as to be suitable for different models of car lamps to achieve the required optical performance.

[0040] Optionally, in this embodiment, the position adjustment of the LED lamp bead 112 is achieved through a specific mechanical mechanism, such as an extension rod 113 or other device.

[0041] According to the above scheme, please refer to Figure 3-7As shown, it can be understood that in this embodiment, the LED lamp bead 112 is arranged on the side of the substrate 111 facing the lens 110, and the LED lamp bead 112 is electrically connected to the substrate 111. The LED lamp bead 112 transmits current through the substrate 111 to work, and the LED lamp bead 112 is further designed to be displaced relative to the substrate 111, so that the LED lamp bead 112 can move to the position of the light entrance 11a when approaching the lens 110, and align with the light entrance 11a, so that the light 100a of the LED lamp bead 112 can be concentrated into the light entrance 11a and emitted from the other side of the lens 110; this structure is designed to be movable on the side of the substrate 111 facing the lens 110, so that the LED lamp bead 112 can be moved to the position of the light entrance 11a and align with the light entrance 11a during assembly, so that the side of the substrate 111 facing the lens 110 can be designed as a plane, thereby simplifying the design difficulty of the PCB and reducing the design and production costs of thick-walled parts.

[0042] It can be understood that the substrate 111 in this embodiment is a PCB board.

[0043] Please refer to Figure 3-4 and Figure 8-9 As shown, preferably, the lens 110 is provided with a light emitting mirror surface 1111 for emitting light 100a outward, and the light emitting mirror surface 1111 is arranged on the side of the lens 110 away from the light entrance 11a. It can be understood that after the light 100a of the LED lamp bead 112 enters the lens 110 through the light entrance 11a, it is reflected and refracted in the lens 110, and then emitted outward from the light emitting mirror surface 1111. In this embodiment, the light emitting mirror surface 1111 is designed as a structure composed of multiple block-shaped reflective mirrors to enhance the light emitting effect of the light emitting mirror surface 1111.

[0044] Please refer to Figure 6-9 As shown, according to the above scheme, preferably, the thick-walled part 100 of the headlight includes an extension rod 113. The thick-walled part 100 of the headlight realizes dynamic adjustment of the position of the LED lamp bead 112 relative to the light entrance 11a of the lens 110 by introducing the extension rod 113. In this technical scheme, the extension rod 113 is arranged between the light entrance 11a of the lens 110 and the substrate 111, and serves as a supporting structure to carry the LED lamp bead 112.

[0045] Please refer to Figure 4-5As shown, preferably, in some embodiments, the extension rod 113 includes a fixing rod 210, the fixing rod 210 is installed on the substrate 111, and the LED lamp bead 112 is installed on the top of the extension rod 113. In this embodiment, the fixing rod 210 is fixedly installed on the substrate 111, and the distance from the top of the fixing rod 210 to the light entrance 11a is designed, so that when the LED lamp bead 112 is installed on the top of the fixing rod 210, the LED lamp bead 112 can be directly aligned with the light entrance 11a.

[0046] It can be understood that the extension rod 113 can perform telescopic movement along the axial direction to move closer to or away from the light entrance 11a, thereby driving the LED lamp bead 112 fixed thereon to move. When the position of the LED lamp bead 112 needs to be adjusted, the extension or shortening of the extension rod 113 can be controlled to allow the LED lamp bead 112 to move closer to or away from the light entrance 11a of the lens 110; in some embodiments, the extension rod 113 can be a mechanical device including an inner and outer sleeve structure, wherein the inner rod can slide inside the outer rod to achieve a change in length; in other embodiments, the extension rod 113 adopts a combination of a spring 412 and a compression rod 411, and uses the elastic force of the spring 412 to drive the telescopic action of the compression rod 411.

[0047] It is understandable that no matter which method is adopted, the extension rod 113 must ensure sufficient rigidity and stability to ensure that the LED lamp bead 112 can maintain the correct posture at any position and will not be displaced due to external vibration and other factors; and the extension rod 113 can electrically conduct the LED lamp bead 112 by setting the body as a conductor structure, so that the LED lamp bead 112 is electrically connected to the substrate 111, or by threading the wires in the extension rod 113, so that the LED lamp bead 112 is electrically connected to the substrate 111 to achieve operation. In addition, the extension rod 113 also needs to be closely matched with the substrate 111 and the possible lens 110 part to ensure the compactness and reliability of the overall structure. Through such a design, the LED lamp bead 112 can be accurately positioned according to actual needs to the position that is most conducive to the concentrated injection of light 100a into the light inlet 11a of the lens 110.

[0048] In this technical solution, the design of the extension rod 113 provides a variety of installation methods to adapt to different structural requirements. Specifically, in some embodiments, the extension rod 113 is directly mounted on the substrate 111, which allows the LED lamp bead 112 to move relative to the lens 110 while maintaining a stable electrical connection with the substrate 111. In this configuration, one end of the extension rod 113 is fixed to the substrate 111, and the other end can be freely extended, thereby driving the LED lamp bead 112 to move closer to or away from the lens 110. In other embodiments, the extension rod 113 is designed to be installed on one side of the lens 110. This arrangement allows the LED lamp bead 112 to move from the side of the lens 110 to the substrate 111. In this way, one end of the extension rod 113 is fixed inside or at the edge of the lens 110, and the other end is connected to the LED lamp bead 112, so that the LED lamp bead 112 can move along the axial direction of the extension rod 113, thereby adjusting its position relative to the light inlet 11a. In a third embodiment, the extension rod 113 can be placed between the substrate 111 and the lens 110, and the two ends are respectively assembled and connected to the substrate 111 and the lens 110. Such a design ensures that the extension rod 113 can be firmly fixed between the two main components, while providing sufficient flexibility to adjust the position of the LED lamp bead 112. In this case, the extension rod 113 may require a more complex mechanical structure to ensure that it can work effectively on both sides while maintaining the compactness of the overall structure.

[0049] For this embodiment, the extension rod 113 is installed on the substrate 111, which means that the main support point of the extension rod 113 is located on the substrate 111, and the telescopic function is realized through the fixed point on the substrate 111. In this way, the distance between the LED lamp beads 112 and the light inlet 11a of the lens 110 can be changed by the extension or shortening action of the extension rod 113, so as to achieve the purpose of accurately controlling the light 100a entering the lens 110. This setting simplifies the installation process of the extension rod 113, and is also convenient for fine-tuning the position of the LED lamp beads 112. The installation position of the extension rod 113 can also be adjusted according to different models of the thick-walled parts 100 of the vehicle lamp to the above two embodiments, which will not be repeated here.

[0050] Please refer to Figure 3 and Figure 6As shown, preferably, the extension rod 113 includes a telescopic rod 211 and a support rod 212. The main function of the telescopic rod 211 is to provide the necessary stability support for the entire telescopic structure, and one end of the telescopic rod 211 is fixedly connected to the base plate 111 or the lens 110. This fixing method ensures that the extension rod 113 can be firmly installed in the internal structure of the thick-walled part 100 of the vehicle lamp, while allowing the other end thereof to be freely extended and retracted; Optionally, in this embodiment, the telescopic rod 211 can be designed to be used in a single or multiple combinations, depending on the required support strength and space restrictions; Further, the support rod 212 is located between the telescopic rods 211 and is specifically used to carry the LED lamp beads 112. One end of the support rod 212 is close to the lens 110, and the LED lamp beads 112 are installed at this position. Through such an arrangement, when the extension rod 113 is extended or shortened, the support rod 212 will drive the LED lamp beads 112 to move along a predetermined path, thereby changing the relative distance between the LED lamp beads 112 and the light inlet 11a of the lens 110.

[0051] Optionally, the support rod 212 may also have a certain adjustment mechanism, such as a fine-tuning screw or a sliding slot, so as to more precisely control the position of the LED lamp bead 112 so that the LED lamp bead 112 is more aligned with the light inlet 11a.

[0052] It can be understood that the entire extension rod 113 realizes dynamic adjustment of the position of the LED lamp bead 112 relative to the light entrance 11a of the lens 110 through the coordinated work of the telescopic rod 211 and the support rod 212. The telescopic rod 211 is responsible for providing structural stability and fixing points, while the support rod 212 focuses on achieving precise positioning and movement of the LED lamp bead 112. This double-layer structure not only simplifies the overall design of the extension rod 113, but also improves the reliability and operability of the system.

[0053] Preferably, the telescopic rod 211 includes a first rod body 311 and a second rod body 312, which are connected to each other in a nested manner, the first rod body 311 is installed inside the second rod body 312, and one end of the second rod body 312 is fixed on the base plate 111, providing a stable support point. This double-layer structure design allows a certain relative motion range between the two rod bodies, and the first rod body 311 can slide freely inside the second rod body 312, thereby driving the LED lamp bead 112 installed thereon to move; further, in order to ensure that the relative position between the first rod body 311 and the second rod body 312 can be accurately controlled, a limit buckle 313 is provided on the first rod body 311, and the limit buckle 313 can move on the first rod body 311, and limit or allow the movement of the first rod body 311 relative to the second rod body 312 by cooperating with a specific position inside the second rod body 312. When the position of the LED lamp bead 112 needs to be fixed, the limit buckle 313 can be operated to lock it in a certain position, thereby fixing the first rod body 311 at a specific position inside the second rod body 312; and when the position of the LED lamp bead 112 needs to be adjusted, the limit buckle 313 can be released to allow the first rod body 311 to slide freely, thereby changing the distance between the LED lamp bead 112 and the light inlet 11a of the lens 110. This design not only provides sufficient flexibility to meet the position adjustment under different lighting requirements, but also ensures that the LED lamp bead 112 can remain stable at any selected position and will not be accidentally displaced due to external factors (such as vibration).

[0054] When the second rod 312 is moved, the opening on the second rod 312 slides to a certain opening position on the first rod 311, and the opening on the second rod 312 is aligned with the opening on the first rod 311. At this time, the limiting buckle 313 can be adjusted so that the limiting buckle 313 can be partially or completely inserted into the opening where the first rod 311 and the second rod 312 overlap, and the second rod 312 is locked to the first rod 311 through friction and the buckle mechanism; when the limiting buckle 313 is not locked in the opening, the second rod 312 can slide freely in the first rod 311, and the user can easily adjust the length or position of the support rod 212. When the support rod 212 needs to be fixed at a certain length, the user only needs to adjust the limit buckle 313 to make the first rod body 311 and the second rod body 312 move relative to each other, and make the second rod body 312 move to the required height, find the opening where the second rod body 312 and the first rod body 311 overlap, and adjust the limit buckle 313 to re-engage it so that it is engaged and locked.

[0055] like Figure 7 As shown, preferably, in other embodiments, the telescopic rod 211 includes a sleeve rod 413, a compression rod 411 and a spring 412 installed in the sleeve rod 413, and the spring 412 is installed on the outside of the compression rod 411, one end of which is connected to the compression rod 411, and the other end is abutted against the bottom end of the support rod 212. When the LED lamp bead 112 is installed on the ball joint 114 at the top of the compression rod 411, the LED lamp bead 112 will generate a force on the support rod 212, which increases the elastic force of the spring 412 on the support rod 212, exceeding the maximum elastic force of the support rod 212 on the spring 412, so that the spring 412 can be triggered to pop outward under the action of external force, and drive the compression rod 411 to stretch outward from the sleeve rod 413, so that the compression rod 411 can be extended accordingly, and the length of the compression rod 411 can be adjusted by rotation, thereby adjusting the overall length or position of the telescopic rod 211. By reasonably designing the stiffness of the spring 412 and the material and size of the compression rod 411, precise control of the movement range and supporting force of the support rod 212 can be achieved; specifically, the support rod 212 includes a compression rod 411 made of elastic material and a spring 412, one end of the compression rod 411 is connected to the base plate 111 by welding or other fixing methods, and the other end is designed as a free end for contacting or connecting with the items to be loaded. The coil spring 412 is sleeved on the compression rod 411, one end of which is fixed to the base plate 111, and the other end is connected to the middle part of the compression rod 411 or a position near the free end. When the LED lamp bead 112 is loaded, the connection position of the spring 412 near the free end is unlocked by installing the LED lamp bead 112, so that the compression rod 411 is decompressed from the original compressed state. This elastic force enables the compression rod 411 to maintain a certain rigidity while being able to extend a certain length so that the LED lamp bead 112 can move at the top end of the compression rod 411, thereby approaching the light entrance 11a and corresponding to the light entrance 11a.

[0056] Please refer to Figure 4-7 As shown, preferably, the thick-walled part 100 of the vehicle lamp further includes a ball joint 114. The design of the ball joint 114 can increase the flexibility of adjusting the position of the LED lamp bead 112. Specifically, the ball joint 114 is installed at one end of the support rod 212 close to the light inlet 11a of the lens 110, and the LED lamp bead 112 is directly fixed on the ball joint 114. The design of the ball joint 114 allows it to rotate and tilt at multiple angles relative to the support rod 212, thereby forming a certain active angle. This structure allows the LED lamp bead 112 to still be fine-tuned through the ball joint 114 even after the position of the support rod 212 is fixed, to ensure that the light 100a can be accurately aligned with the light inlet 11a of the lens 110.

[0057] In a specific embodiment, the telescopic rod 211 is adjusted to an ideal position through the sleeve structure of the first rod body 311 and the second rod body 312 and the limit buckle 313. At this time, if it is necessary to further optimize the relative angle between the LED lamp bead 112 and the light entrance 11a of the lens 110, the ball joint 114 can be used for fine adjustment. The ball joint 114 is usually composed of two hemispherical parts, one of which is fixed to the support rod 212, and the other can rotate freely around the center point. The LED lamp bead 112 is installed on this rotatable part. By gently adjusting it manually or with tools, the LED lamp bead 112 can change its illumination direction within a certain range.

[0058] In this technical solution, the design of the ball joint 114 allows the LED lamp bead 112 to form an active angle relative to the support rod 212, and its angle range is limited to between 0° and 60°. This design provides a wide adjustment range for the LED lamp bead 112, and the operator can gently turn the ball head manually to adjust it within the range of 0° to 60°. When the ideal angle is reached, use a locking screw to fix the ball head. In this way, even if the vehicle encounters bumps during driving, the LED lamp bead 112 can maintain the set angle and will not move. This design not only simplifies the multi-angle adjustment process of the LED lamp bead 112, but also ensures precise optical control in different application scenarios.

[0059] In this technical solution, the lens 110 is designed to have multiple light inlets 11a, and each light inlet 11a corresponds to an LED lamp bead 112. This design of multiple light inlets 11a allows the headlight to produce more complex lighting patterns or provide a wider lighting coverage. Each LED lamp bead 112 is supported by a ball joint 114, and its position and angle relative to the respective light inlet 11a can be adjusted as needed; in a specific embodiment, assuming that there are twenty-eight light inlets 11a on the lens 110, there will be twenty-eight corresponding LED lamp beads 112, and each LED lamp bead 112 is connected by an independent ball joint 114. These ball joints 114 allow each LED lamp bead 112 to adjust its illumination angle individually so that its light 100a can accurately enter the corresponding light inlet 11a. When the position of a certain LED lamp bead 112 needs to be adjusted, the ball head on the ball joint 114 can be gently turned manually until the LED lamp bead 112 is aligned with the light inlet 11a. Once the adjustment is completed, the locking mechanism (such as a screw or a buckle) on the ball joint 114 can be used to fix the position of the ball head. In this way, even during the operation of the vehicle, each LED lamp bead 112 can maintain its set angle and will not be displaced due to external vibrations and other factors. Each LED lamp bead 112 can be closely attached to the edge of the light inlet 11a, or a certain gap can be set as needed to meet different optical design requirements.

[0060] In summary, the present invention provides a thick-walled part of a car lamp. The key to the design is that the position of the LED lamp bead can be adjusted so that it can be close to or away from the lens. When the LED lamp bead is adjusted to a position close to the lens, it can be more accurately aligned with the light entrance of the lens, so that the emitted light is concentrated and incident on the lens. After being processed by the internal structure of the lens, these light rays are emitted from the other side of the lens. Therefore, under this structure, the substrate can be planarly designed, which simplifies the design and production costs of the substrate. In addition, the simplicity of the thick-walled part of the car lamp is improved. Through such a structural setting, the entire car lamp system can flexibly adjust the position of the light source in the lamp housing of different models of car lamps, so that it is suitable for different models of car lamps to achieve the required optical performance.
