DETAILED DESCRIPTION

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

[0036] Embodiment 1:

[0037] In order to effectively solve the above problems, as shown in the accompanying drawings of the specification Figure 1-Figure 8 As shown, a motorcycle headlight that is easy to install includes a lamp core 1, a transparent lampshade 2, a spotlight cover 3, a mounting ring 4 and a mounting seat 5. The transparent lampshade 2 is fixed to the motorcycle through the mounting ring 4. The spotlight cover 3 is arranged inside the transparent lampshade 2. The mounting seat 5 is arranged in the middle of the spotlight cover 3. The lamp core 1 is arranged in a mounting cavity 51 inside the mounting seat 5, and the lamp beads 11 at the head of the lamp core 1 extend out of the mounting cavity 51 and are close to the transparent lampshade 2. The lamp body 12 of the lamp core 1 is located inside the mounting cavity 51 and is electrically connected to the power supply component inside the mounting seat 5.

[0038] The area surrounded by the surface of the spotlight cover 3 facing away from the head of the wick 1 and the inner wall of the mounting ring 4 is a temperature control cavity 31. The outer surface of the mounting ring 4 is provided with an air inlet 41, which communicates with the interior of the temperature control cavity 31.

[0039] The middle part of the lamp body 12 is evenly provided with heat sinks 13, and the side wall of the installation cavity 51 is provided with cooling holes 52, which point to the end of the heat sink 13 close to the lamp bead 11, and the cooling holes 52 are communicated with the interior of the temperature control cavity 31;

[0040] The side wall of the installation cavity 51 is further provided with an air guide hole 53 , which is close to an end of the heat sink 13 away from the lamp bead 11 , and communicates with the outside.

[0041] Specific working process: the motorcycle headlight of the present application is installed at the corresponding position of the front end of the motorcycle, and the power supply control pipeline is connected, so that during driving, the transparent lampshade 2 faces the windward side and is washed by the airflow; when the headlight is started during driving of the motorcycle, the chip and the light-emitting control element inside the lamp body 12 are started by the controller, so that the lamp beads 11 at the end start to emit light; at the same time, the spotlight cover 3 surrounding the lamp beads 11 reflects and gathers the illumination light emitted by the lamp beads 11, so that the light released by the lamp beads 11 is concentrated to form a light beam that passes through the transparent lampshade 2 and is emitted to the outside world, illuminating the external environment and playing a lighting role;

[0042] In this process, because the power of the wick 1 is relatively large, the heat dissipated is radiated to the surrounding transparent lampshade 2, the mounting ring 4 and other parts. Therefore, an air inlet hole 41 is provided on the outer surface of the mounting ring 4, and the air inlet hole 41 is located at the connection part between the mounting ring 4 and the transparent lampshade 2. Therefore, when the motorcycle is running, the oncoming airflow flows along the arc surface of the transparent lampshade 2, and directly passes through the air inlet hole 41 after contacting the air inlet hole 41 and enters the temperature control chamber 31, so that the airflow around the air inlet hole 41 flows rapidly, and the impact of the airflow prevents external dust and impurities from penetrating into the connection part between the mounting ring 4 and the transparent lampshade 2 near the air inlet hole 41.

[0043] As the airflow enters the temperature control chamber 31, a cooling airflow is formed, which cools the connection between the mounting ring 4 and the transparent lampshade 2 from the inside to the outside inside the temperature control chamber 31, thereby ensuring that the connection between the mounting ring 4 and the transparent lampshade 2 is cooled more evenly, reducing the structural deformation of the connection due to the local temperature difference, which affects the connection and installation stability between the mounting ring 4 and the transparent lampshade 2, thereby ensuring the installation stability of the entire motorcycle headlight;

[0044] Furthermore, as the cooling airflow enters the temperature control cavity 31, it contacts the back of the spotlight cover 3 which constitutes a part of the inner wall of the temperature control cavity 31, thereby taking away the heat absorbed by the spotlight cover 3 due to focusing, thereby controlling the temperature of the spotlight cover 3, reducing the deformation and distortion of the spotlight cover 3 due to excessive temperature caused by continuous working heat accumulation, and ensuring the normal operation of the spotlight cover 3;

[0045] The vertical cross section of the annular temperature control cavity 31 is approximately triangular in structure, and the portion close to the cooling hole 52 gradually narrows, presenting a conical structure. Therefore, when the cooling airflow flows along the temperature control cavity 31 toward the cooling hole 52, the flow velocity of the cooling airflow increases due to the narrow tube effect, and the cooling airflow is accelerated to pass through the interconnected cooling holes 52 and flow into the installation cavity 51, enter the gap between the heat sink 13 in the middle of the lamp body 12, and flow along the gap between the heat sink 13;

[0046] During this process, the flowing cooling airflow takes away the heat of the heat sink 13 that contacts it through the heat conducting material, and the heat flows along the gap between the heat sink 13 along with the flowing cooling airflow until it flows to the outside from the air guide hole 53 and takes away the heat, thereby cooling down the middle part of the lamp body 12. This can prevent the accumulation of heat generated by the continuous power-on operation of the chips and other light-emitting electronic components inside the lamp body 12, which may cause the temperature of the lamp body 12 to be too high, thereby affecting the normal operation of the lamp beads 11 at the end of the lamp body 12. The present application forms a stable cooling airflow flow path by setting the air inlet hole 41, the temperature control cavity 31, the cooling hole 52 and the air guide hole 53, and utilizes the airflow brought by the start-up of the motorcycle to continuously cool and control the temperature of the lamp body 12 corresponding to the working motorcycle headlight, thereby ensuring its normal operation and improving the lighting stability and driving safety factor during driving.

[0047] Embodiment 2:

[0048] On the basis of the first embodiment, the air inlet holes 41 are distributed in an annular manner around the central axis of the mounting ring 4, and the outer surface of the mounting ring 4 corresponding to the air inlet holes 41 is recessed to form an air gathering portion 42, the opening of the air inlet holes 41 is located in the middle of the air gathering portion 42, and an interception net 421 is laid on the outer surface of the air gathering portion 42;

[0049] A purification layer 32 is provided near the air guide hole 53 of the temperature control chamber 31 . The purification layer 32 is filled with purification fillers. A limiting net 321 is provided at the edge of the purification layer 32 to limit the purification fillers inside.

[0050] Specific workflow: On the basis of the specific workflow in the first embodiment, in order to ensure the connection and installation stability between the mounting ring 4 and the transparent lampshade 2, the mounting joint between the mounting ring 4 and the transparent lampshade 2 is arranged inside the air gathering portion 42, so that it is protected by the interception net 421; in this way, the particle dust impurities contained in the external airflow are separated by the interception net 421, and the particle dust impurities are prevented from entering the connection and installation gap between the mounting ring 4 and the transparent lampshade 2, affecting the installation stability between the mounting ring 4 and the transparent lampshade 2;

[0051] Furthermore, due to the concave setting of the air gathering portion 42, during driving, when the airflow flows toward the surroundings along the arc surface of the transparent lampshade 2, it contacts the air gathering portion 42, and the concave surface of the air gathering portion 42 hinders the flow of the airflow, and the flow velocity of the blocked part of the airflow slows down and accelerates to flow from the air inlet 41, and then enters the temperature control cavity 31, participates in cooling the components such as the spotlight cover 3 and the electronic components of the lamp body 12 inside the motorcycle headlight, and brings the heat to the external environment;

[0052] In order to prevent the impurities contained in the cooling air flow from causing harm to the internal components of the motorcycle headlights and affecting the normal operation of the motorcycle headlights; first, the external airflow flowing into the air inlet 41 is preliminarily purified through the filter structure interception net 421 to separate larger particle dust impurities. In order to facilitate the inflow of airflow, the interception net 421 has a smaller mesh size and a larger aperture; then the airflow needs to pass through the purification layer 32 in the temperature control cavity 31, and pass through the purification filler gap inside the purification layer 32. The purification filler can be a mixture of silica gel drying particles and activated carbon adsorption particles, which can absorb fine impurities, water vapor and corrosive oil fume pollution gases in the cooling airflow to ensure the purification of the cooling airflow; the clean cooling airflow after purification in this way participates in the heat absorption cooling treatment of the internal components of the headlights, which ensures the cooling effect while reducing the adhesion of impurities to the internal electronic components, causing their corrosion to increase, thereby affecting the normal operation of the headlights.

[0053] Embodiment three:

[0054] On the basis of the second embodiment, the inner ring end of the annular spotlight cover 3 is slidably embedded in the mounting groove 54 on the outer ring of the mounting seat 5;

[0055] The mounting groove 54 is provided with a positioning groove 541, which is distributed in an annular manner around the central axis of the spotlight cover 3. A positioning block 33 is provided at a portion of the inner ring end of the spotlight cover 3 corresponding to the positioning groove 541. The positioning block 33 is slidably embedded in the positioning groove 541. The opening of the air guide hole 53 is located on the inner wall of the mounting groove 54. A through hole 331 is provided in the middle of the positioning block 33, and the through hole 331 extends upward into the temperature control cavity 31.

[0056] The positioning block 33 is slidably embedded in the slide groove 332 on the inner ring end of the spotlight cover 3, and the positioning block 33 and the slide groove 332 are connected by an elastic member;

[0057] A positioning rod 34 is provided on the end of the positioning block 33, and the positioning rod 34 is slidably embedded in the temperature control chamber 31. The through hole 331 extends through the positioning rod 34, so that the positioning rod 34 is a tubular structure; the end of the positioning rod 34 is embedded in the purification layer 32 and is slidably connected to the limiting net 321 at the edge of the purification layer 32, and inflation holes 341 are evenly arranged on the side wall of the positioning rod 34.

[0058] Specific workflow: Based on the specific workflow in Example 2, during the installation process between the mounting seat 5 and the spotlight cover 3, the end of the mounting seat 5 is embedded into the inner circle of the spotlight cover 3; specifically, when the angle of the mounting seat 5 is adjusted and the mounting seat 5 is pushed to be embedded after alignment, the positioning block 33 on the end of the inner circle of the spotlight cover 3 is embedded into the mounting groove 54 on the surface of the mounting seat 5, and as the positioning block 33 slides along the mounting groove 54 until the end of the positioning block 33 is embedded into the positioning groove 541 on the inner wall of the mounting groove 54, the combination of the positioning block 33 and the positioning groove 541 realizes the position determination of the mounting seat 5, and at this time, the cooling hole 52 on the inner wall of the positioning groove 541 is directly opposite to the through hole 331 on the end of the positioning block 33, so that the cooling airflow inside the temperature control cavity 31 can smoothly pass through the through hole 331 on the positioning block 33, and then flow into the cooling hole 52 in the positioning groove 541, and then flow into the mounting cavity 51 to realize the cooling of the lamp body 12 inside the mounting cavity 51, thereby improving the working environment of the lamp body 12;

[0059] The bottom end of the positioning block 33 is an arc-shaped structure, and the inner wall of the positioning groove 541 is provided with an arc-shaped depression near the opening of the cooling hole 52, so that when the positioning block 33 is close to the opening of the cooling hole 52, the bottom of the arc-shaped positioning block 33 is smoothly embedded in the depression of the positioning groove 541, so that the cooling hole 52 is more smoothly aligned with the through hole 331 on the end of the positioning block 33, so as to realize the smooth transmission of the cooling airflow;

[0060] Furthermore, the positioning block 33 and the slide groove 332 on the spotlight cover 3 are elastically connected for sliding, so that the combination between the elastically connected positioning block 33 and the positioning groove 541 is more convenient to adjust, and the surface of the end of the positioning block 33 is set to an elastic material to reduce the wear of the positioning block 33 caused by the combination of the positioning block 33 and the positioning groove 541; and the positioning rod 34 at the end of the positioning block 33 is embedded in the purification filler gap inside the purification layer 32, and the cooling airflow penetrating the purification layer 32 contacts the inflation hole 341 on the side wall of the positioning rod 34, and then flows into the opposite cooling hole 52 along the through hole 331 inside the positioning rod 34, so as to realize the transmission of the cooling airflow; because the inflation hole 341 is located on the positioning rod 34, with the vibration of the motorcycle, the positioning block 33 drives the positioning rod 34 to vibrate relative to the slide groove 332, thereby prompting the positioning rod 34 to transmit the vibration to the purification filler, so that the purification filler vibrates, and prevents the purification filler from agglomerating into a group in the local area, which affects the stability of the cooling airflow.

[0061] Embodiment 4:

[0062] On the basis of the third embodiment, the outer surface of the positioning rod 34 located inside the temperature control chamber 31 is wrapped with a ring-shaped collection net 342, and the side wall of the collection net 342 facing the inflation hole 341 is convex outward to form an expansion portion 343; the end of the positioning rod 34 is located outside the purification layer 32, and the end of the positioning rod 34 is provided with a guide plate 344, and the surface of the guide plate 344 is an arc-shaped structure;

[0063] The inner wall of the temperature control chamber 31 facing the purification layer 32 is evenly provided with guide grooves 345 , and the guide grooves 345 extend from the direction close to the air inlet hole 41 to the direction close to the cooling hole 52 .

[0064] Specific workflow: Based on the specific workflow in Example 3, the outer surface of the positioning rod 34 includes a collecting net 342, so that a gap is maintained between the purification filler and the opening of the inflation hole 341, so as to avoid the purification filler causing the opening of the inflation hole 341 to be blocked, and the cooling air flow is kept to pass through the collecting net 342 smoothly, be sucked into the inflation hole 341 and flow along the through hole 331, and participate in the cooling process of the internal electronic components;

[0065] Furthermore, because the portion of the collecting net 342 facing the air filling hole 341 is sunken outward to form an expansion portion 343, the gap between the purification filler and the air filling hole 341 is increased, so that the collection of the cooling airflow that penetrates and flows through the gap of the purification filler is smoother; with the vertical vibration of the positioning rod 34, the positioning rod 34 and the collection net 342 connected thereto and the purification filler are relatively slid and rubbed, especially the expansion portion 343 protruding outward stirs the purification filler during the vibration process, so as to promote the flow mixing between the purification fillers, and promote the purification filler in the purification layer 32 to maintain a loose and porous state, thereby ensuring the smooth penetration and flow of the cooling airflow;

[0066] Furthermore, a sliding connection can be provided between the positioning rod 34 and the positioning block 33. Specifically, the positioning rod 34 can slide through the positioning block 33 and be connected at the joint by a spring; thus, when the downward cooling airflow impacts the guide plate 344, the guide plate 344 can drive the positioning rod 34 to slide, thereby better stirring the purification filler and maintaining its loose state;

[0067] Restriction nets 321 are provided on both sides of the purification layer 32 and on the side close to the air inlet 41, so that a gap is maintained between the purification layer 32 and the inner walls of the temperature control chamber 31 on both sides; in the process of the cooling airflow flowing into the temperature control chamber 31, a part of the cooling airflow flows toward both sides under the guidance of the arc surface of the guide plate 344, and then flows along the guide grooves 345 on the inner walls of both sides of the temperature control chamber 31 to the gap between the inner wall of the temperature control chamber 31 and the restriction net 321, and then penetrates from both sides to the middle positioning rod 34 through the restriction net 321, thereby increasing the contact degree between the cooling airflow and the purification filler. , so that the purification filler can be reused; and by dispersing the cooling airflow close to the purification layer 32, it contacts the purification filler in multiple directions, so that the impact of the cooling airflow on the purification filler is also dispersed, and the elastically vibrating positioning rod 34 stirs and combs the purification filler to ensure the loose and breathable state of the purification filler. In this way, the cooling airflow can be prevented from being compacted due to the impact of a single airflow from the air inlet 41 into the cooling hole 52, resulting in a reduction in the clearance of the purification filler, a decrease in the permeability, and the occurrence of problems affecting the smooth flow of the cooling airflow.

[0068] Embodiment five:

[0069] On the basis of the fourth embodiment, the inner wall of the installation cavity 51 is provided with a cooling cavity 55, the interior of the cooling cavity 55 is filled with a coolant, the cooling cavity 55 is an annular structure, and surrounds the heat sink 13 on the middle lamp body 12; the coolant here is a type commonly used in existing electronic devices;

[0070] The surface of the lamp body 12 is evenly provided with guide blocks 121 at the gaps between the heat sinks 13. The guide blocks 121 have a triangular cross section, and the side of the guide blocks 121 close to the cooling holes 52 is an inclined surface structure, and the side of the guide blocks 121 close to the air guide holes 53 is a vertical surface structure.

[0071] An adjustment groove 551 is provided at the position of the inner wall of the installation cavity 51 facing the gap area between the guide blocks 121. The adjustment groove 551 is recessed toward the inside of the cooling cavity 55, and the internal cross section of the adjustment groove 551 is triangular.

[0072] Specific working process: Based on the specific working process in the fourth embodiment, when the cooling airflow flows in the gap between the inner wall of the installation cavity 51 and the lamp body 12, the gap between the cooling cavity 55 and the lamp body 12 is filled, so that the heat is transferred from the lamp body 12 to the outside, thereby improving the cooling effect on the lamp body 12; specifically, when the airflow enters the interior of the installation cavity 51 and is dispersed into multiple streams and flows along the gap area between the heat sinks 13 toward the direction close to the air guide hole 53, the cooling airflow contacts the guide block 121, and flows along the inclined surface on the guide block 121 toward the adjustment groove 551 close to the inner wall of the installation cavity 51, enters the interior of the adjustment groove 551 and contacts the inner wall of the adjustment groove 551, and after transferring the heat absorbed from the lamp body 12 to the coolant inside the cooling cavity 55, the cooling airflow then flows along the inclined surface of the inner wall of the adjustment groove 551 to the next guide hole 53. Block 121, thus promoting the flowing cooling airflow to flow along a continuous W-shaped flow trajectory in the gaps between the heat sinks 13, and to flow between the mutually staggered guide blocks 121 and the adjustment slots 551; on the one hand, the continuously curved flow trajectory increases the residence time of the cooling airflow in the gaps between the heat sinks 13, fully absorbing the heat of the heat sink 13, thereby improving the temperature conditions of the electronic components inside the lamp body 12; on the other hand, the flowing cooling airflow jumps between the guide block 121 and the adjustment slots 551, transferring the heat of the lamp body 12 to the coolant in the cooling chamber 55, adjusting the temperature of the cooling airflow itself, reducing the situation where the cooling airflow contacts the heat sink 13 away from the cooling hole 52 and the heat dissipation effect is limited due to the high temperature, so that the cooling airflow can cool the heat sink 13 and the lamp body 12 more comprehensively and efficiently.

[0075] The outer surface of the mounting housing 6 is provided with an air outlet 61, which is communicated with the air guide hole 53, and a filter mesh structure is provided outside the air outlet 61 to intercept the intrusion of dust and impurities from the outside;

[0076] Specific workflow: Based on the specific workflow in the first embodiment, the combination of the mounting shell 6 and the mounting ring 4 allows the mounting seat 5 and the wick 1 to be wrapped and protected, and the entire motorcycle headlight is also fixed to the vehicle body; and because the airflow near the outer ring surface of the mounting shell 6 where the air outlet 61 is located flows horizontally during the movement of the vehicle body, the flow velocity near the outlet of the air outlet 61 increases and the air pressure decreases. Under the action of the pressure difference, the internal cooling airflow is prompted to flow out from the air outlet 61 after passing through the air guide hole 53, thereby achieving continuous outflow of the cooling airflow;

[0077] Furthermore, when the motorcycle is parked, a protective annular rubber ring can be provided at the corresponding position of the air outlet 61, so that the air outlet 61 is closed and protected, and then opened during driving to ensure that the air outlet 61 is unobstructed and can be put into normal use.

[0078] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
