Description

Technical Field

[0001] This invention relates to the field of vehicle accessories, and in particular to a diffuse reflection vehicle lamp structure. Background Technology

[0002] With the continuous development of the automotive industry, vehicle lights, as important safety components and aesthetic elements, are receiving increasing attention for their lighting effects, optical uniformity, and aesthetic appeal. In recent years, diffuse reflection headlights have been widely used in the automotive lighting field due to their ability to provide soft, uniform light patterns and effectively avoid glare. At the same time, the increasingly diverse and personalized designs of vehicle lights have placed higher demands on the compactness of the internal space and the integration of the optical system. Currently, the optical system of vehicle lights typically employs a structure of reflectors combined with thick-walled components to achieve light reflection and emission.

[0003] However, the existing diffuse reflection vehicle lamp structure still has the following shortcomings: First, the installation of the reflector bowl and the lamp body usually requires the use of multiple independent parts for assembly, which not only makes the installation process complicated and the assembly efficiency low, but also easily causes installation errors and affects optical performance; Second, the lamp body (light source) is usually directly fixed on the housing or circuit board, which is inconvenient to operate when the lamp body needs to be replaced or maintained, and is easy to damage the internal structure of the lamp. Summary of the Invention

[0004] In view of this, the present invention aims to propose a diffuse reflection vehicle lamp structure to solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows: The present invention proposes a diffuse reflection vehicle lamp structure, including a housing with an internal cavity, a fixing plate fixedly disposed at the opening of the housing, a plurality of reflective components spaced apart in the housing, a thick-walled member fixedly disposed on the fixing plate, and a lamp cover fixedly disposed on the housing and wrapped around the outside of the thick-walled member. The reflective assembly includes a mounting groove formed on the fixed plate, a reflector bowl fixedly set in the mounting groove with an open end inside the housing, a partition fixedly set inside the housing, a bottom plate fixedly set on the top of the partition, and a mounting plate slidably set on the top surface of the bottom plate along its length direction. One end of the mounting plate extends to the outside of the housing. A light-transmitting opening is formed at the bottom of the reflector bowl. A placement groove is formed on the mounting plate. A lamp holder slot is detachably provided in the placement groove. A mounting hole for mounting the lamp body is formed on the lamp holder slot. The lamp body is located below the light-transmitting opening. The reflector bowl has reflective protrusions spaced apart inside. The light from the lamp body is reflected by the reflector bowl onto the thick-walled component. The outer and inner sides of the thick-walled component are respectively provided with a first pattern and a second pattern.

[0006] Furthermore, a wire passage groove is provided in the placement groove, a wire hole communicating with the wire passage groove is provided in the mounting hole, and an outlet communicating with the wire passage groove is fixedly provided on the side wall of the mounting plate.

[0007] Furthermore, the top surface of the partition is also provided with a limiting component, which includes a horizontal plate fixedly disposed on the top surface of the partition located on one side of the mounting plate, and inclined blocks fixedly disposed at intervals on the horizontal plate. The mounting plate is provided with an inner groove that cooperates with the inclined blocks.

[0008] Furthermore, the first pattern consists of multiple spherical patterns, while the second pattern is in a layered state.

[0009] Furthermore, a heat dissipation groove is fixedly provided on the top of the partition along the length of the mounting plate. The heat dissipation groove is in contact with the side wall of the mounting plate, and the two ends of the heat dissipation groove are open and extend through to the outside of the housing.

[0010] Furthermore, a wavy heat-conducting wire is fixedly provided on the side of the heat dissipation groove that contacts the mounting plate.

[0011] Furthermore, a heat-conducting block for heat dissipation is fixedly installed inside the heat dissipation groove.

[0012] Furthermore, the top surface of the partition is provided with a vertical rod for support, one end of which is fixedly connected to the partition, and the other end is fixedly connected to the top of the housing or an adjacent partition.

[0013] Compared with the prior art, the present invention has the following advantages: In this invention, the mounting plate is slidably arranged along the length of the base plate. During installation, the mounting plate, together with the lamp slot, can be pushed into the housing to the predetermined position. The assembly process is quick and convenient, effectively reducing the number of parts and assembly time.

[0014] One end of the mounting plate extends to the outside of the housing. The lamp holder is detachably mounted in the placement slot of the mounting plate, and the lamp holder has mounting holes for mounting the lamp body. When the lamp body needs to be replaced or maintained, simply slide the mounting plate outward along the base plate to remove the lamp holder along with the lamp body from the housing, without disassembling the housing or other components such as the reflector. The lamp holder and the placement slot are detachably connected, allowing for direct replacement of either the lamp holder or the lamp body when damaged, resulting in low maintenance costs and simple operation.

Those skilled in the art can understand the specific meaning of the above terms in this invention in light of the specific circumstances.

[0020] The following will refer to the appendix. Figures 1 to 12 The present invention will be described in detail with reference to the embodiments.

[0021] Overall, the present invention discloses a diffuse reflection vehicle lamp structure, including a housing 1 with an internal cavity, a fixing plate 2 fixedly disposed at the opening of the housing 1, a plurality of reflective components spaced apart inside the housing 1, a thick-walled member 9 fixedly disposed on the fixing plate 2, and a lamp cover 10 fixedly disposed on the housing 1 and wrapped around the outside of the thick-walled member 9. Among them, such as Figures 2 to 8 As shown, the reflective assembly includes a mounting groove 201 on a fixed plate 2, a reflective bowl 3 fixedly mounted in the mounting groove 201 with an open end inside the housing 1, a partition 4 fixedly mounted inside the housing 1, a base plate 402 fixedly mounted on the top of the partition 4, and a mounting plate 5 slidably mounted on the top surface of the base plate 402 along its length. One end of the mounting plate 5 extends to the outside of the housing 1. A light-transmitting opening 302 is provided at the bottom of the reflective bowl 3. A placement groove 501 is provided on the mounting plate 5. A lamp holder 6 is detachably provided in the placement groove 501. A mounting hole 601 for mounting a lamp body 603 is provided on the lamp holder 6. The lamp body 603 is located below the light-transmitting opening 302. Reflective protrusions 301 are spaced apart inside the reflective bowl 3. The light from the lamp body 603 is reflected by the reflective bowl 3 onto the thick-walled member 9. The outer and inner sides of the thick-walled member 9 are respectively provided with a first pattern 901 and a second pattern 902.

[0022] In this embodiment, the mounting plate 5 is slidably disposed along the length of the base plate 402. During installation, the mounting plate 5, together with the lamp slot 6, can be pushed into the housing 1 to the predetermined position. The assembly process is quick and convenient, effectively reducing the number of parts and assembly time.

[0023] One end of the mounting plate 5 extends to the outside of the housing 1. The lamp holder 6 is detachably mounted in the placement slot 501 of the mounting plate 5, and the lamp holder 6 has a mounting hole 601 for mounting the lamp body 603. When the lamp body 603 needs to be replaced or maintained, simply slide the mounting plate 5 outward along the base plate 402 to remove the lamp holder 6 together with the lamp body 603 from the housing 1, without disassembling the housing 1 or other components such as the reflector 3. The lamp holder 6 and the placement slot 501 are detachably connected, so when the lamp body 603 is damaged, the lamp holder 6 or the lamp body 603 itself can be directly replaced, resulting in low maintenance costs and simple operation.

[0024] It should be noted that the inner surface of the reflector bowl 3 has reflective protrusions 301 formed by a vacuum aluminum plating process. The function of the reflective protrusions 301 is to cause multiple diffuse reflections of light within the reflector bowl 3, thereby converting the point light source into a uniform surface light source. The reflector bowl 3 has an overall bowl-shaped or trumpet-shaped structure, with a light-transmitting opening 302 at its bottom. The light-transmitting opening 302 is circular or rectangular in shape, allowing the light emitted by the lamp body 603 to enter the interior of the reflector bowl 3.

[0025] It should be further explained that one end of the mounting plate 5 extends to the outside of the housing 1, and the protruding end is provided with a handle or pull ring, which makes it easy for the operator to pull out the mounting plate 5. The mounting plate 5 is provided with a placement groove 501, which is a rectangular groove whose size is adapted to the outer dimensions of the lamp holder 6.

[0026] Preferably, the lamp holder 6 and the placement slot 501 are detachably fixed by means of snap-fit ​​connection, magnetic connection, or screw connection. The lamp holder 6 is made of a metal material with good thermal conductivity (such as aluminum alloy), and its bottom has a mounting hole 601 for mounting the lamp body 603. The mounting hole 601 is a threaded hole or a through hole. The lamp body 603 is fixedly mounted on the lamp holder 6 through the mounting hole 601. The lamp body 603 is an LED light source, and its light-emitting surface faces upward and is directly opposite the light-transmitting opening 302 at the bottom of the reflector bowl 3.

[0027] In this embodiment, the thick-walled component 9 is fixedly mounted on the fixing plate 2 and located in the light emission path of the reflector bowl 3. The thick-walled component 9 is injection molded from PMMA or PC transparent material, and its overall structure is plate-shaped or block-shaped. The outer side of the thick-walled component 9 (i.e., the side facing the lampshade 10) is provided with a first pattern 901, and the inner side of the thick-walled component 9 (i.e., the side facing the reflector bowl 3) is provided with a second pattern 902.

[0028] It should be understood that the spherical pattern has light diffusion characteristics, which can uniformly scatter the light emitted from inside the thick-walled member 9, making the spatial distribution of the emitted light more uniform. The second pattern 902 is in a layered state, that is, it is composed of multiple optical surfaces arranged in layers along the thickness or height direction of the thick-walled member 9, forming a stepped or layered structure.

[0029] The specific installation method of the lamp body 603 is as follows: First, insert the lamp body 603 into the mounting hole 601 of the lamp holder 6, and fix the lamp body 603 to the lamp holder 6 by threaded connection or welding. Then, snap the lamp holder 6 into the placement groove 501 of the mounting plate 5 and lock it in place by clips or screws. Finally, push the mounting plate 5 into the housing 1 along the guide groove of the base plate 402, so that the lamp body 603 is located directly below the light transmission opening 302 of the reflector bowl 3.

[0030] When the lamp body 603 needs to be replaced, simply pull the handle at one end of the mounting plate 5 to slide the mounting plate 5 outward along the base plate 402 to the outside of the housing 1. Then, remove the lamp holder 6 from the placement slot 501, replace it with a new lamp body 603 or a new lamp holder 6, and then push the mounting plate 5 back into its original position. The entire replacement process does not require disassembling the housing 1, fixing plate 2, reflector 3, or thick-walled component 9, making the operation simple and quick.

[0031] In practice, the lamp body 603 is powered on and emits light. After being emitted from the lamp body 603, the light enters the interior of the reflector bowl 3 through the light-transmitting opening 302 at the bottom of the reflector bowl 3. Inside the reflector bowl 3, the light encounters the spaced-apart reflective protrusions 301 and undergoes multiple diffuse reflections. After thorough mixing, it forms uniform scattered light that exits from the open end of the reflector bowl 3, illuminating the inner side of the thick-walled component 9. The light first undergoes initial light distribution and angle adjustment through the second pattern 902 on the inner side of the thick-walled component 9, then continues to propagate inside the thick-walled component 9, and finally undergoes final diffusion through the first pattern 901 on the outer side of the thick-walled component 9 before exiting the thick-walled component 9. The emitted light passes through the lamp cover 10 and illuminates the front of the vehicle headlight.

[0032] Based on the above settings, as a preferred embodiment, such as Figure 7 and Figure 8 As shown, a wire passage groove 502 is provided in the placement groove 501, and a wire hole 602 communicating with the wire passage groove 502 is provided in the mounting hole 601. An outlet 503 communicating with the wire passage groove 502 is fixedly provided on the side wall of the mounting plate 5.

[0033] In practice, the power cord of the lamp body 603 can pass through the wire hole 602 in the mounting hole 601 into the wire channel 502, and then be uniformly led out to the outside of the housing 1 through the outlet 503. Through the above-mentioned embedded wiring channel design, the power cord is orderly stored and guided inside the mounting plate 5, avoiding messy tangling of cables or interference and friction caused by sliding with the mounting plate 5, effectively preventing cable wear and short circuit risks.

[0034] In this embodiment, as Figure 10As shown, the top surface of the partition 4 is also provided with a limiting component. The limiting component includes a horizontal plate 7 fixedly disposed on the top surface of the partition 4 on one side of the mounting plate 5, and an inclined block 701 fixedly disposed at intervals on the horizontal plate 7. The mounting plate 5 is provided with an inner groove 702 that cooperates with the inclined block 701.

[0035] In practice, after the mounting plate 5 is pushed into place along the base plate 402, the inclined block 701 precisely engages with the inner groove 702 of the mounting plate 5, thus limiting and locking the mounting plate 5. The cooperation between the inclined block 701 and the inner groove 702 effectively prevents the mounting plate 5 from shifting forward or backward under the vibration or impact of vehicle movement, ensuring that the lamp body 603 is always precisely positioned directly below the light-transmitting opening 302 of the reflector bowl 3, guaranteeing the long-term stability of the optical system. When it is necessary to remove the mounting plate 5 for maintenance, only a certain pulling force needs to be applied, and the inclined surface of the inclined block 701 will slide relative to the inclined surface of the inner groove 702, allowing the inclined block 701 to disengage from the inner groove 702 and unlock.

[0036] As a preferred structure in this embodiment, such as Figure 9 As shown, a heat dissipation groove 8 is fixedly provided on the top of the partition plate 4 along the length of the mounting plate 5. The heat dissipation groove 8 is in contact with the side wall of the mounting plate 5. The two ends of the heat dissipation groove 8 are open and extend through to the outside of the shell 1.

[0037] The heat generated by the lamp body 603 during operation is conducted to the mounting plate 5 through the lamp holder 6. The side wall of the mounting plate 5 is in contact with the wall of the heat dissipation groove 8, and the heat is conducted to the heat dissipation groove 8 through the contact surface. The air in the heat dissipation groove 8 becomes less dense after being heated and rises, and is discharged to the outside of the housing 1 through the openings at both ends of the heat dissipation groove 8.

[0038] Based on the above configuration, a wave-shaped heat-conducting wire 801 is fixedly provided on the side of the heat dissipation groove 8 that contacts the mounting plate 5, and a heat-conducting block 802 for heat dissipation is fixedly provided inside the heat dissipation groove 8.

[0039] In addition, the top surface of the partition 4 is provided with a vertical rod 401 for support. One end of the vertical rod 401 is fixedly connected to the partition 4, and the other end is fixedly connected to the top of the housing 1 or the adjacent partition 4.

[0040] Heat is rapidly conducted along the wavy heat-conducting wire 801 to the side wall of the heat dissipation slot 8, and then conducted through the heat dissipation slot 8 to the internal heat-conducting block 802, which increases the heat dissipation effect.

[0041] In addition, such as Figure 6 As shown, the top surface of the partition 4 is provided with a vertical rod 401 for support. One end of the vertical rod 401 is fixedly connected to the partition 4, and the other end is fixedly connected to the top of the housing 1 or an adjacent partition 4. This configuration improves the integrity and durability of the internal structure of the housing 1.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
