Description

Technical Field

[0001] The invention relates to the technical field of motorcycle accessories, in particular to a reflective headlamp for a motorcycle. Background Art

[0002] In order to meet the lighting requirements of high beam / low beam, the existing motorcycle reflective LED headlights need to use multiple 3W white light LED particles. However, there are the following problems in conventional motorcycle reflective LED headlights:

[0003] 1. Since multiple LEDs in each lamp cavity are mounted on a radiator, the heat of each LED particle affects each other, resulting in the need for sufficient heat dissipation area to ensure the heat dissipation performance of the LED particles. Therefore, the size of the radiator is relatively large and the weight is heavy.

[0004] 2. Since the radiator is the main installation body, other components (such as upper reflector / lower reflector / baffle, etc.) need to be installed on the radiator separately (such as Figure 8 , Fig. 9 and Fig.10 ), which makes the structure of connecting the radiator with other components more complicated. Therefore, the radiator can only be made by die casting.

[0005] 3. As the radiator is the main installation body, its strength will have a greater impact on the lamp, so the aluminum material of the radiator can only be ADC12 aluminum alloy.

[0006] 4. Since the thermal conductivity of ADC12 is only 96W / m*℃, the heat sink needs to be larger in size to ensure the heat dissipation performance of the LED particles.

[0007] 5. Affected by the shapes of different lamps, the position and layout of LED particles vary greatly. Therefore, the heat sinks and modules in different lamps cannot be retained at all and can only be newly designed and developed. Summary of the invention

[0008] In order to solve the above problems, the purpose of the present invention is to provide a motorcycle reflective headlamp. Without affecting the heat dissipation performance, a new design of the reflective headlamp module is adopted, so that the weight and area of ​​the radiator are greatly reduced, and the upper reflector, lower reflector and baffle are combined into a whole, thereby reducing the cost of molds and production and processing, thereby greatly reducing the production cost of the lamp.

[0009] To achieve the above object, the present invention adopts the following technical solutions: It includes a lamp body, characterized in that: the lamp body includes a lamp shade, a lamp housing assembled on the lamp shade, and a reflective headlamp module installed on the lamp housing; the reflective headlamp module includes a reflector, and a plurality of module assemblies assembled on the reflector; the reflector includes a base and a plurality of lamp bowls constructed on the base, and the base and the plurality of lamp bowls are integrally formed; each module assembly is correspondingly constructed above a lamp bowl of the reflector, and includes a small radiator, a circuit board connected to the small radiator, and a single light source arranged on the circuit board; the small radiator is positioned and assembled with the reflector, an opening is provided at the upper end of the lamp bowl, and the single light source is positioned between the small radiator and the opening; a plurality of positioning plates are provided on the base and extend along the side where the lamp bowl is located, and a positioning slot is formed by cutting from the outer edge of the positioning plate to the inner end of the positioning plate; the small radiator is an integral plate and is bent, including a main body part and a folded edge part, the outer end of the positioning slot is in an "eight" shape, and the main body part is inserted and matched with the positioning slot; at least one end of the inner sides of the two ends of the main body part forms a right-angle cut, and the right-angle cut is in abutting cooperation with the inner end of the positioning slot; a plurality of docking seats extend outward from the upper end of the outer wall of the lamp bowl, screw posts are provided on the docking seats along the direction parallel to the main body part, and a plurality of screw holes are opened at the lower end of the folded edge part and respectively correspond to the screw posts on the plurality of docking seats; positioning pins extend outward from the docking seats, and the outer ends of the positioning pins extend beyond the outer end surfaces of the screw posts, and a plurality of positioning holes are opened on the folded edge part and respectively sleeved and matched with the positioning pins on the plurality of docking seats.

[0010] In the above technical solution, in a motorcycle reflective headlamp, the radiator no longer serves as the installation main body, but the reflector serves as the installation main body, and the radiator is divided into a plurality of small radiators and assembled on the reflector as auxiliary components. The structure of the radiator is greatly simplified. Under this solution, the total weight of the plurality of small radiators is reduced by about 50% compared with the integrated radiator solution, greatly reducing the cost.

[0011] Moreover, due to the miniaturization of the radiator, its strength requirement is relatively low, and it can be made by stamping process, which is more convenient.

[0012] In addition, a single small radiator corresponds to a single light source, and the light sources above each lamp bowl do not interfere with each other, avoiding the heat influence between the light sources and keeping the heat dissipation performance of the light sources good.

[0013] This solution only involves the positioning and assembly between the module assembly and the reflector, and the installation / maintenance is extremely convenient.

[0014] Furthermore, if the reflector is used as the installation body, the module assembly can be miniaturized and can be used as a universal standard module. In the subsequent development of lamps, if necessary, only the corresponding positioning structure needs to be modified. Basically, there is no need for a new design and it can be used directly, saving a lot of manpower and material resources.

[0015] In addition, compared with the prior art, when assembling the module, the upper reflector, the lower reflector and the baffle are respectively installed on the radiator; in this technical solution, multiple lamp bowls and the base are integrally formed into a reflector, which increases the stability of the structure, and because the number of injection molded products is reduced, the processing cost of injection molds and product injection molding is greatly reduced.

[0016] The plug-in cooperation between the positioning slot and the main body of the radiator can quickly realize the pre-installation of the small radiator and the reflector, and the outer end of the positioning slot is in the shape of an "eight" so that the main body can be quickly inserted into the positioning slot or quickly pulled out when it is about to be disengaged from the positioning slot, so as to avoid the inconvenience of calibration and insertion when the main body is plugged into the positioning slot, and the outer end of the positioning plate may be easily deformed and worn during the plugging. It is only necessary to hold the right-angle cutout against the inner end of the positioning slot to quickly and accurately position the main body and the positioning slot, and prevent the main body of the radiator from shifting to the left / right along the positioning slot during installation. The multiple screw holes of the folded edge on the small radiator correspond to the multiple screw columns respectively, which can facilitate screwing in the screws to fasten the small radiator and the reflector at multiple points; and the cooperation of the positioning pin and the positioning hole can not only realize the rapid positioning of the folded edge so that it is convenient for fixing with the screw column, but also prevent the longitudinal movement of the folded edge, further stabilizing the position of the folded edge.

[0017] Preferably, at least one of the plurality of positioning holes is a circular hole that fits the positioning pin, and at least one is a waist-shaped hole. In this technical solution, when the positioning hole and the positioning pin are assembled, a positioning pin is first plugged into the circular hole. The setting of the waist-shaped hole can control a certain assembly error within a reasonable range, so that the positioning pin can smoothly fall into the waist-shaped hole, and prevent individual positioning pins and positioning holes from being unable to be accurately positioned when there is an assembly error.

[0018] Preferably, the small heat sink is made by stamping 1060 aluminum plate. In this technical solution, the aluminum content of 1060 aluminum plate reaches 99.6%, also known as pure aluminum plate. The thermal conductivity of this material is as high as 234W / m*℃. After using this material, the size of the heat sink can be made smaller. A 1060 aluminum plate with a size of about 37*38*20mm can meet the heat dissipation requirements of a 3W white light LED particle when it is working, further miniaturizing the heat sink, greatly reducing the weight, and saving materials. In addition, the 1060 aluminum plate has high formability under the stamping process and is easier to operate in terms of process.

[0019] Preferably, the single light source is arranged on the lower end surface of the circuit board, the circuit board is fitted on the lower end surface of the main body, and a thermal conductive silicone is arranged between the circuit board and the main body, a plurality of positioning posts are arranged on the main body, a plurality of docking holes for plugging and matching with the plurality of positioning posts are opened on the circuit board, and a plurality of corresponding bolt holes are arranged on the main body and the circuit board and fixedly connected by inserting bolts. In this technical solution, corresponding to the setting of a small radiator, the above-mentioned circuit board is also miniaturized, and a thermal conductive silicone is arranged between the radiator and the radiator, so that the heat dissipation performance of the circuit board is further improved; in addition, the cooperation between the docking hole and the positioning post facilitates the installation and positioning of the circuit board and the radiator, and the radiator and the circuit board are bolted after positioning.

[0020] Preferably, an escape hole is provided from the outer end of the main body to the folded edge, the cross section of the escape hole is trapezoidal, and the diameter gradually increases from bottom to top. In this technical solution, the setting of the escape hole can facilitate the installation of the lamp sheath. In addition, the escape hole is connected to the opening at the upper end of the lamp bowl, which can further increase the heat dissipation performance of the LED particles; it should be noted here that there is a gap between the upper end of the lamp bowl and the module assembly, and this permeability also has a certain heat dissipation function.

[0021] Preferably, the front end of the positioning pin is a conical tip, and a plurality of guide slides are regularly arranged around the inner end of the tip. In this technical solution, the front end tip of the positioning pin can facilitate the positioning hole to be quickly clamped on the positioning pin, and avoid wear when the folded edge is sleeved with the positioning pin. In addition, the provision of the guide slide can also avoid wear and can smoothly allow the folded edge to pass through the guide slide and be clamped with the positioning pin.

[0022] Preferably, the module assembly has four groups, and two groups are arranged in the upper and lower parts, and the adjacent module assemblies are arranged horizontally symmetrically relative to the reflector. In this technical solution, in order to meet the requirements of the motorcycle reflective high beam / low beam and maintain the stability of the light pattern, the adjacent module assemblies are arranged horizontally symmetrically so that the light sources therein are accurately positioned.

[0038] like Figures 1 to 7 A motorcycle reflective headlamp shown in the figure comprises a lamp body, wherein the lamp body comprises a lampshade, a lamp shell mounted on the lampshade, and a reflective headlamp module mounted on the lamp shell; the reflective headlamp module comprises a reflector 1, and a plurality of module assemblies mounted on the reflector 1; the reflector 1 comprises a base 7 and a plurality of lamp bowls 2 constructed on the base 7, and the base 7 and the plurality of lamp bowls 2 are integrally formed; each module assembly is correspondingly constructed above a lamp bowl 2 of the reflector 1, and comprises a small radiator 3, a circuit board 4 connected to the small radiator 3, and a single light source 5 arranged on the circuit board 4; the small radiator 3 is positioned and assembled with the reflector 1, an opening 6 is provided at the upper end of the lamp bowl 2, and the single light source 5 is positioned between the small radiator 3 and the opening 6.

[0039] In the above technical solution, the radiator is no longer used as the installation body, but the reflector is used as the installation body. The radiator is divided into multiple small radiators 3 as an auxiliary part and assembled on the reflector 1. The structure of the radiator is greatly simplified. Under this solution, the total weight of multiple small radiators 3 is reduced by about 50% relative to the integrated radiator solution, greatly reducing the cost.

[0040] In addition, due to the miniaturization of the radiator, its strength requirement is relatively low and it can be manufactured using a stamping process, which is more convenient.

[0041] In addition, a single small heat sink 3 corresponds to a single light source 5, and the light sources 5 above each lamp bowl 2 do not interfere with each other, avoiding the heat influence between the light sources 5, so that the heat dissipation performance of the light source 5 remains good. It should be noted here that the light source 5 is a 3W white light LED particle.

[0042] This solution only involves the positioning and assembly between the module assembly and the reflector 1, and installation / maintenance is also extremely convenient.

[0043] Furthermore, if the reflector 1 is used as the installation body, the module assembly is miniaturized and can be used as a universal standard module. In the subsequent development of lamps, if necessary, only the corresponding positioning structure needs to be modified, and basically no new design is required. It can be used directly, saving a lot of manpower and material resources.

[0044] In addition, compared to the prior art, when assembling the module, the upper reflector 400, the lower reflector 401 and the baffle 300 are respectively installed on the radiator; in this technical solution, multiple lamp bowls 2 and the base 7 are integrally formed into a reflector 1, which increases the stability of the structure, and since the number of injection molded products is reduced, the processing cost of the injection mold and product injection molding is greatly reduced.

[0045] Furthermore, a plurality of positioning plates 8 are provided on the base 7 and extend along the side where the lamp bowl 2 is located, and positioning slots 9 are formed on the positioning plates 8 and cut from the outer edge of the positioning plates 8 to the inner end of the positioning plates 8; the small radiator 3 is an integral plate and is bent, including a main body 10 and a folded edge 11, and the outer end of the positioning slot 9 is in an "eight" shape, and the main body 10 is plugged into the positioning slot 9. In this technical solution, the plug-in fit between the positioning slot 9 and the radiator main body 10 can quickly realize the pre-installation of the small radiator 3 and the reflector 1, and the "eight" shape of the outer end of the positioning slot 9 can facilitate the main body 10 to quickly extend into the positioning slot 9 or to be quickly pulled out when it is about to be disengaged from the positioning slot, so as to avoid inconvenience in calibration and insertion when the main body 10 is plugged into the positioning slot 9, and the outer end of the positioning slot 9 may be easily deformed and worn during the plugging.

[0046] Furthermore, at least one of the two ends of the inner side of the main body 10 forms a right-angle cutout 12, and the right-angle cutout 12 abuts against the inner end of the positioning slot 9. In this technical solution, the main body 10 and the positioning slot 9 can be quickly and accurately positioned by simply pressing the right-angle cutout 12 against the inner end of the positioning slot 9, and the main body 10 is prevented from shifting to the left / right along the positioning slot when the radiator is installed.

[0047] Furthermore, a plurality of docking seats 13 are provided on the upper end of the outer wall of the lamp bowl 2, and a screw column 14 is provided on the docking seat 13 in a direction parallel to the main body 10. A plurality of screw holes 15 are provided on the lower end of the folding portion 11, which correspond to the screw columns 14 on the plurality of docking seats 13 respectively. A positioning pin 16 is provided on the docking seat 13, and the outer end of the positioning pin 16 exceeds the outer end surface of the screw column 14. A plurality of positioning holes 17 are provided on the folding portion 11, which respectively fit with the positioning pins 16 on the plurality of docking seats 13. In this technical solution, the plurality of screw holes 15 of the folding portion 11 on the small radiator 3 correspond to the plurality of screw columns 14 respectively, so that the small radiator 3 can be fastened to the reflector 1 at multiple points by screwing in the screws. The cooperation between the positioning pin 16 and the positioning hole 17 can not only realize the rapid positioning of the folding portion 11 to facilitate its fixation with the screw column 14, but also prevent the longitudinal movement of the folding portion 11, further stabilizing the position of the folding portion.

[0048] Furthermore, at least one of the plurality of positioning holes 17 is a circular hole that fits the positioning pin 16, and at least one is a waist-shaped hole 18. In this technical solution, when the positioning hole 17 and the positioning pin 16 are assembled, a positioning pin 16 is first plugged into the circular hole, and the setting of the waist-shaped hole 18 can control a certain assembly error within a reasonable range, so that the positioning pin 16 can smoothly fall into the waist-shaped hole 18, and prevent individual positioning pins 16 and positioning holes 17 from being unable to be accurately positioned when there is an assembly error.

[0049] Furthermore, the small heat sink 3 is made by stamping 1060 aluminum plate. In this technical solution, the aluminum content of 1060 aluminum plate reaches 99.6%, also known as pure aluminum plate. The thermal conductivity of this material is as high as 234W / m*℃. After using this material, the size of the heat sink can be made smaller. A 1060 aluminum plate with a size of about 37*38*20mm can meet the heat dissipation requirements of a 3W white light LED particle when it is working, further miniaturizing the heat sink, greatly reducing the weight, and saving materials. In addition, the 1060 aluminum plate has high formability under the stamping process and is easier to operate in terms of process.

[0050] Furthermore, a single light source 5 is arranged on the lower end surface of the circuit board 4, the circuit board 4 is fitted and installed on the lower end surface of the main body 10, and a heat-conducting silica gel is arranged between the circuit board 4 and the main body 10, a plurality of positioning posts 19 are arranged on the main body 10, a plurality of docking holes 20 are opened on the circuit board 4 to be plugged and matched with the plurality of positioning posts 19, and a plurality of corresponding bolt holes 21 are arranged on the main body 10 and the circuit board 4 and are fixedly connected by inserting bolts. In this technical solution, corresponding to the setting of the small radiator 3, the circuit board 4 is also miniaturized, and a heat-conducting silica gel is arranged between the radiator and the circuit board 4, so that the heat dissipation performance of the circuit board 4 is further improved; in addition, the cooperation between the docking holes 20 and the positioning posts 19 facilitates the installation and positioning of the circuit board 4 and the radiator, and the radiator and the circuit board 4 are bolted after positioning.

[0051] Furthermore, an escape hole 22 is provided from the outer end of the main body 10 to the folded edge 11. The cross section of the escape hole 22 is trapezoidal, and the diameter gradually increases from bottom to top. In this technical solution, the setting of the escape hole 22 can facilitate the installation of the lamp cover. In addition, the escape hole 22 is connected to the opening at the upper end of the lamp bowl 2, which can further increase the heat dissipation performance of the LED particles. It should be noted here that there is a gap between the upper end of the lamp bowl 2 and the module assembly, and this permeability also has a certain heat dissipation function.

[0052] Furthermore, the front end of the positioning pin 16 is a conical tip 24, and a plurality of guide slides 23 are regularly arranged around the inner end of the tip 24. In this technical solution, the front end tip 24 of the positioning pin 16 can facilitate the positioning hole 17 to be quickly clamped on the positioning pin 16, and avoid wear when the folding edge portion 11 is sleeved with the positioning pin 16. In addition, the provision of the guide slide 23 can also avoid wear and can smoothly allow the folding edge 11 to pass through the guide slide 23 and be clamped with the positioning pin 16.

[0053] Furthermore, there are four groups of module assemblies, two groups arranged in the upper and lower parts, and adjacent module assemblies are arranged horizontally symmetrically relative to the reflector 1. In this technical solution, in order to meet the requirements of the motorcycle reflective high beam / low beam and maintain the stability of the light pattern, adjacent module assemblies are arranged horizontally symmetrically so that the light sources therein are accurately positioned.

[0054] In this specific embodiment, Figure 8 , Fig. 9 and Fig.10As shown, in the existing motorcycle reflective headlight, a large radiator 100 is used as the installation body, and the baffle 300, the upper module 200, the lower module 201, the upper reflector 400 and the lower reflector 401 are all assembled on the large radiator 100. In this case, multiple LEDs on the upper / lower modules are assembled on one radiator, and the heat of each LED particle affects each other. For this reason, the large radiator 100 needs a sufficient heat dissipation area to ensure the heat dissipation performance of multiple LED particles. For this reason, its size is generally relatively large, and due to the strength requirements and the complexity of the assembly structure, it can only be made of die-casting of aluminum alloy of model ADC12, and the thermal conductivity of aluminum alloy of model ADC12 is only 96W / m*℃.

[0055] Due to the general thermal conductivity, the large heat sink 100 made of die-cast aluminum alloy of ADC12 is large in size and heavy in weight.

[0056] In addition, due to the influence of different lamp shapes, the position and layout of LED particles vary greatly. Therefore, the heat sinks and modules in different lamps cannot be retained at all and can only be newly designed and developed.

[0057] In summary, the new solution relates to a motorcycle reflective headlamp, which uses an integrally formed reflector 1 as the installation body, and a module assembly with a small radiator 3 as an auxiliary component installed on the reflector 1. Under this structure:

[0058] 1. Since the structure of the radiator is greatly simplified, the processing technology can be changed from the original die-casting process to the stamping process to complete the production of the radiator, which greatly reduces the processing cost of the radiator.

[0059] 2. Since the module assemblies corresponding to each lamp bowl 2 are independent of each other, the heat sink area required by the LED particles is greatly reduced, and the thermal conductivity of the 1060 aluminum material used in the stamping process is relatively high, resulting in a significant reduction in the size / weight of the heat sink, which greatly reduces the material cost of the heat sink.

[0060] 3. Since the reflector 1 is the installation body, the module assembly can be assembled by inserting it from the rear of the reflector 1. Therefore, the upper reflector / lower reflector and baffle parts do not need to be separated and can be combined into a complete whole. Due to the reduction in the number of injection molded parts, the processing costs of injection molds and product injection molding are greatly reduced.

[0061] 4. Due to the miniaturization of the module assembly, it can be used as a universal standard module. In the subsequent development of lamps, there is basically no need for a new design and it can be used directly.

[0062] The above scheme has completely optimized the motorcycle reflective headlight in terms of structure, material and process, greatly reducing production costs and having a wide range of applications.
