Description

Technical Field

[0001] The present invention relates to the technical field of automobile headlights, in particular to a modular assembly automobile headlight. Background Art

[0002] Most existing vehicle lighting systems use traditional fixed installation methods, where the LED lamp holder is usually installed on the lamp base using screws or clips. However, this traditional design faces several problems. First, the heat dissipation problem of LED lamps has long plagued the design of vehicle lights. Especially under high-intensity lighting, LED lamps generate very high heat, often requiring complex heat dissipation systems to ensure their normal operation. Second, traditional installation methods often rely on fixed and stable connection structures, which not only increases manufacturing costs but also limits installation flexibility and maintenance convenience. In addition, the existing technology is relatively simple in the design of heat dissipation and electrical connections, failing to effectively combine the functions of heat dissipation and power supply, resulting in LED lamps being prone to overheating and damage under high-power conditions. Furthermore, in terms of modular design, the existing system lacks sufficient customizability. Users often need to replace the entire lamp to meet different lighting needs, rather than simply adjusting the modules to meet personalized lighting needs. Summary of the Invention

The drive motor 113 is also fixedly mounted on the drive motor support ring 104. The output shaft of the drive motor 113 is fixedly matched with the rotating cover 112.

[0025] The working principle of the modular assembly vehicle lamp disclosed in the present invention is as follows: the user chooses to insert the LED lamp mounting seat 131 into the installation insertion tube 124 at different positions according to needs, or inserts the LED lamp mounting seat 131 into all the installation insertion tubes 124 (the more, the greater the brightness), so as to meet customized needs. Specifically, the LED lamp mounting base 131 is inserted into the mounting insertion tube 124 (including the LED lamp 132 on the LED lamp mounting base 131). During this process, the bar permanent magnet 134 on the LED lamp mounting base 131 will gradually approach the positioning permanent magnet block 125. At this time, under the magnetic constraint of the two positioning permanent magnet blocks 125 and the bar permanent magnet 134, the LED lamp mounting base 131 will be driven to rotate (because the bar permanent magnet 134 is embedded and fixed on the LED lamp mounting base 131, the two are regarded as a whole. When the magnetic poles of the bar permanent magnet 134 are the same as the magnetic poles of the positioning permanent magnet block 125, repulsion will occur. At this time, under the action of the repulsive force, the LED lamp mounting base 131 will rotate; when the magnetic poles of the bar permanent magnet 134 are the same as the magnetic poles of the positioning permanent magnet block 125, repulsion will occur. At this time, under the action of the repulsive force, the LED lamp mounting base 131 will rotate; when the magnetic poles of the bar permanent magnet 134 are the same as the magnetic poles of the positioning permanent magnet block 125, When the poles are different, they attract each other. At this time, under the action of magnetic attraction, the LED lamp mounting base 131 rotates, and then the magnetic poles of the bar permanent magnet 134 are aligned with the positioning permanent magnet block 125, and the positions of the two corresponding docking joints 133 are determined), so that the docking joint 133 is aligned with the through hole opened in the magnetic attraction mounting plate 119. (It should be noted that the docking joint 133 and the through hole opened in the magnetic attraction mounting plate 119 constitute a quick connector (a quick connector for liquid or gas transportation). This quick connector does not have a locking structure. Its locking structure is replaced by the friction between the docking joint 133 and the rubber ring 121, the magnetic attraction between the positioning permanent magnet block 125 and the bar permanent magnet 134, and the magnetic attraction between the LED lamp mounting base 131 and the magnetic attraction mounting plate 119. At this time, the docking joint 133 is connected to the interior of the coolant circulation cover 116, and the dynamic conductive slip ring plate 123 and the static conductive slip ring plate 135 are magnetically attracted and conductive. At this time, the LED lamp 132 can obtain electrical energy.

[0026] Since the LED lamp 132 generates a large amount of heat during operation, it is necessary to dissipate heat for the LED lamp 132. At this time, the drive motor 113 and the electromagnetic confinement ring 105 are started, and the output shaft of the drive motor 113 drives the rotating cover 112 to rotate, and the rotating cover 112 drives the gear ring 106 to rotate, and the gear ring 106 drives the central gear 108 to rotate through the limiting gear 107. During this process, since the electromagnetic confinement ring 105 is in the started state, the rotation of the limiting gear mounting disk 111 will be constrained by the magnetic force of the electromagnetic confinement ring 105, so that the limiting gear mounting disk 111 cannot rotate (or is restricted from rotating, depending on the magnitude of the magnetic force), so the limiting gear 107 cannot revolve. At this time, the rotation of the central gear 108 will drive the transmission main shaft 109 to rotate, and the rotation of the transmission main shaft 109 drives the heat dissipation impeller 129, the temperature conduction transmission column 130 and the circulation impeller 127 to rotate. The rotation of the circulating impeller 127 will drive the coolant inside the circulating cooling drive chamber 126 to rotate. At this time, the coolant will be affected by the centrifugal force and flow from the return rectangular channel 117 to the inlet rectangular channel 118, and then pass through the coolant circulation cover 116 and the magnetic mounting plate 119 in turn to form multiple independent spaces separated by the partition ribs 110. The coolant flowing from one independent space to another will pass through the docking joint 133, the LED lamp mounting seat 131, and the docking joint 133 in turn, so that the coolant can cool the LED lamp 132. The high-temperature coolant that has absorbed the heat will flow back into the circulating cooling drive chamber 126 through the reflux rectangular channel 117 again, and then come into contact with the circulating impeller 127. The circulating impeller 127 absorbs the temperature and transfers it to the heat dissipation impeller 129 through the temperature conduction transmission column 130. The rotation of the heat dissipation impeller 129 will drive the air to pass through the heat dissipation impeller 129, thereby driving the heat dissipation impeller 129 itself to dissipate heat. In this process, the air will come into contact with the heat dissipation impeller 129 through the air inlet 101 and the guide channel 102. At the same time, the heat sink 103 will also absorb part of the temperature on the coolant circulation cover 116 (a plurality of air holes are provided on the contact surface between the heat sink 103 and the coolant circulation cover 116 to balance the pressure difference when the guide sliding rod 122 moves, or there is a gap sliding fit between the guide sliding rod 122 and the partition rib 110), thereby reducing the temperature of the coolant inside the coolant circulation cover 116 and reducing the burden of the circulating impeller 127 on absorbing heat. The rotation of the heat dissipation impeller 129 will drive the nearby air to be thrown toward the heat sink 103, thereby cooling the heat sink 103.When the vehicle is in motion, there will be convection between the heat sink 103 and the air intake 101. At this time, the drive motor 113 and the electromagnetic confinement ring 105 can be turned off (depending on the vehicle speed). The external air will pass through the heat sink 103, thereby directly dissipating the heat of the heat sink 103. At the same time, the air will also enter the air intake 101, and then be guided by the guide channel 102 to blow the air flow to the heat dissipation impeller 129, thereby driving the heat dissipation impeller 129 to rotate. The rotation of the heat dissipation impeller 129 will drive the circulation impeller 127 to rotate through the temperature conduction transmission column 130, thereby driving the circulation of the coolant. This removes the heat generated during the operation of the LED lamp 132. At the same time, since the electromagnetic confinement ring 105 is in a power-off state, the electromagnetic confinement ring 105 no longer restricts the revolution of the limiting gear 107, that is, it restricts the rotation of the gear mounting disk 111. When the heat dissipation impeller 129 drives the center gear 108 to rotate through the transmission main shaft 109, it will drive the limiting gear 107 to revolve. Since there is resistance to the rotation of the rotor of the drive motor 113, the revolution and rotation of the limiting gear 107 at this time make the center gear 108 idle, thereby reducing the rotation resistance of the heat dissipation impeller 129.
