Technical Field

[0001] The utility model belongs to the technical field of automobile headlights, and particularly relates to an automobile headlight with good heat dissipation effect. Background Technique

[0002] The vehicle lamp is a tool for road lighting when the vehicle is driving at night, and also a tool for sending various vehicle driving signals. Vehicle lamps are generally divided into headlamps, tail lamps, turn signals, etc. A large amount of heat is generated when the vehicle lamp works and needs to be dissipated in time. Otherwise, it will damage the components inside the vehicle lamp. Therefore, existing vehicle lamps usually dissipate heat by combining a heat sink and a cooling fan. The existing cooling fan is usually installed by matching the pin holes on the outer shell with multiple fasteners. When later maintenance and replacement are needed, specific disassembly tools are required, and the operation is inconvenient. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an automobile headlight with good heat dissipation effect to solve the problems mentioned in the above background technique in view of the above defects.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows: An automobile headlight with good heat dissipation effect includes an LED lamp body. A radiator assembly is arranged at the bottom end of the LED lamp body. An annular mounting plate is arranged on the radiator assembly. A cooling fan assembly is detachably arranged on the mounting plate. Arc-shaped chutes are symmetrically arranged on the inner wall of the mounting plate. Openings respectively communicated with the two arc-shaped chutes are symmetrically arranged at the bottom end of the mounting plate. Vertically arranged connecting arms are symmetrically arranged on the cooling fan assembly. A slider matching the opening is arranged at the bottom end of the connecting arm. A clamping groove is arranged on the top surface of the arc-shaped chute at a position far from the opening. A locking component for engaging with the clamping groove is arranged at the top end of the slider. An unlocking component for separating the locking component from the clamping groove is arranged at the top end of the mounting plate.

[0005] Further, the radiator assembly includes heat conducting columns arranged at the bottom end of the LED lamp body, a heat dissipation base arranged at the bottom end of the heat conducting columns, and heat dissipation fins evenly and spacedly arranged on the heat dissipation base.

[0006] Further, a plurality of heat dissipation bumps are annularly arranged at the bottom end of the outer surface of the heat conducting column.

[0007] Further, the locking component includes a first fixed seat, a second fixed seat, a telescopic rod, a clamping block, and a spring. A groove is arranged at the top end of the slider. The first fixed seat is arranged at the top end inside the groove. The bottom end of the telescopic rod is connected to the first fixed seat. The second fixed seat is arranged at the top end of the telescopic rod. The clamping block is arranged at the top end of the second fixed seat. The spring is sleeved on the outer surface of the telescopic rod. Under the action of the spring force, the clamping block is located outside the clamping groove.

[0008] Furthermore, the unlocking component includes an upper limit block, a lower limit block, and a connecting column. The lower limit block is movably arranged up and down in a card slot above the locking component. The upper limit block is arranged at the top end of the mounting plate. The connecting column is arranged at the bottom end of the upper limit block, and the bottom end of the connecting column penetrates through the mounting plate and is connected to the lower limit block.

[0009] Furthermore, the heat dissipation fan component includes an annular housing, blades and a driving member arranged inside the annular housing. The connecting arm is arranged at the top end of the annular housing.

[0010] The beneficial effects of the present utility model are as follows:

[0011] Through the cooperative setting of the mounting plate, the arc-shaped chute, the opening, the connecting arm, the slider, the card slot, the locking component, and the unlocking component, the heat dissipation fan component inserts the slider into the arc-shaped chute through the opening. When the slider abuts against the top end inside the arc-shaped chute, it forms a squeeze on the locking component, causing it to undergo elastic deformation and enter the slider. Rotate the slider so that the slider slides along the arc-shaped chute and is misaligned with the opening until the slider abuts against the inner side wall of the arc-shaped chute. At the same time, the locking component corresponds to the card slot, and the squeezing force disappears. The locking component rebounds and resets to engage with the card slot. When the locking component does not separate from the card slot and the slider corresponds to the opening, the heat dissipation fan component will not separate from the mounting plate, and its connection is firm and stable. When it is necessary to disassemble the heat dissipation fan component, by pressing the unlocking component, the locking component is separated from the card slot, and by rotating the heat dissipation fan component, the slider can be made to correspond to the opening, and then the heat dissipation fan component can be removed. There is no need for specific tool operation, and the later disassembly and installation maintenance are more convenient. Description of the Drawings

Specific embodiments

[0021] The present utility model will be further described below with reference to the accompanying drawings.

[0022] Refer to Figure 1-7 As shown, the automobile headlamp with good heat dissipation effect includes an LED lamp body 1. A heat sink assembly 2 is arranged at the bottom end of the LED lamp body 1. The heat sink assembly 2 conducts the heat generated by the LED lamp body 1 to the rear for heat dissipation. An annular mounting plate 3 is arranged on the heat sink assembly 2. A heat dissipation fan assembly 4 is detachably arranged on the mounting plate 3. The heat dissipation fan assembly 4 cooperates with the heat sink assembly 2 to further improve the heat dissipation effect and efficiency of the LED lamp body 1.

[0023] Arc-shaped chutes 301 are symmetrically formed on the inner wall of the mounting plate 3. Openings 302 respectively communicating with the two arc-shaped chutes 301 are symmetrically arranged at the bottom end of the mounting plate 3. The openings 302 are perpendicular to the arc-shaped chutes 301. Vertically arranged connecting arms 5 are symmetrically arranged on the heat dissipation fan assembly 4. A slide block 6 matching the opening 302 is arranged at the bottom end of the connecting arm 5. The slide block 6 can move inside the arc-shaped chute 301. The slide block 6 enters the inside of the arc-shaped chute 301 through the opening 302. As the heat dissipation fan assembly 4 rotates, the slide block 6 rotates inside the arc-shaped chute 301 until the slide block 6 abuts against the inner side wall of the arc-shaped chute 301, and the slide block 6 is misaligned with the opening 302. In the case where the slide block 6 does not correspond to the opening 302, the heat dissipation fan assembly 4 will not be separated from the mounting plate 3. When it is necessary to disassemble the heat dissipation fan assembly 4, only need to rotate the heat dissipation fan assembly 4 to make the slide block 6 correspond to the opening 302, then the slide block 6 can be moved out from the opening 302, and the heat dissipation fan assembly 4 can be disassembled. Its installation and disassembly are convenient, without the need for specific tool operation, which is convenient for later maintenance and replacement.

[0024] A clamping groove 303 is formed on the top surface of the arc-shaped sliding groove 301 at one end far away from the opening 302. A locking component is arranged at the top end of the sliding block 6 and is engaged with the clamping groove 303. An unlocking component 7 for driving the locking component to separate from the clamping groove is arranged at the top end of the mounting plate 3. After the sliding block 6 enters the arc-shaped sliding groove 301, the locking component is restricted by the inner wall of the arc-shaped sliding groove 301 and enters the interior of the sliding block 6, where it undergoes elastic deformation. Until the sliding block 6 rotates to correspond to the clamping groove 303, the force squeezing the locking component disappears, and it engages with the clamping groove 303, making the connection strength between the heat dissipation fan assembly 4 and the mounting plate higher, the connection more firm, and it is not easy to rotate automatically due to the bumps and vibrations of the vehicle. The unlocking component is used to separate the locking component from the clamping groove 303, facilitating the disassembly of the heat dissipation fan assembly 4.

[0025] The radiator assembly 2 includes a heat conducting column 201 arranged at the bottom end of the LED lamp body 1, a heat dissipation base 202 arranged at the bottom end of the heat conducting column 201, and heat dissipation fins 203 evenly spaced on the heat dissipation base 202. The heat conducting column 201 transfers heat to the heat dissipation base 202, and heat dissipation is carried out through the heat dissipation fins 203. A plurality of heat dissipation bumps 204 are annularly arranged at the bottom end of the outer surface of the heat conducting column 201. The heat dissipation protrusions 204 can further increase its heat dissipation area, improving the heat dissipation effect and efficiency.

[0026] The locking component includes a first fixing seat 801, a second fixing seat 802, a telescopic rod 803, a clamping block 804, and a spring 805. A groove 806 is formed at the top end of the sliding block 6. The first fixing seat 801 is arranged at the bottom end inside the groove 806. The bottom end of the telescopic rod 803 is connected to the first fixing seat 801. The second fixing seat 802 is arranged at the top end of the telescopic rod 803. The clamping block 804 is arranged at the top end of the second fixing seat 802. The spring 805 is sleeved on the outer surface of the telescopic rod 803, and both ends of the spring 805 are in contact with the first fixing seat 801 and the second fixing seat 802 respectively. Under the action of the spring 805, the clamping block 804 is located outside the clamping groove 303. After the sliding block 6 enters the arc-shaped sliding groove 301, the clamping block 804 first contacts the inner wall of the arc-shaped sliding groove 301. Until the sliding block 6 contacts the inner wall of the arc-shaped sliding groove 301, it squeezes the clamping block 804, causing the second fixing seat 802 to move closer to the first fixing seat 801, the telescopic rod 803 to contract, and squeezing the spring 805 to cause elastic deformation. The clamping block 804 enters the groove 806. Until the sliding block 6 drives the clamping block 804 to move to the clamping groove 303, the squeezing force disappears, the spring 805 rebounds, and the clamping block 804 moves towards the clamping groove 303 to engage with the clamping groove 303, locking the heat dissipation fan assembly 4 to the mounting plate 3.

[0027] The unlocking component 7 includes an upper limit block 701, a lower limit block 702 and a connecting column 703. The lower limit block 702 is movably arranged up and down in a clamping groove 303 above the locking component. The upper limit block 701 is arranged at the top of the mounting plate 3. The connecting column 703 is arranged at the bottom end of the upper limit block 701, and the bottom end of the connecting column 703 penetrates through the mounting plate 3 and is connected to the lower limit block 702. The upper limit block 701 and the lower limit block 702 cooperate to enable the connecting column 703 to stably reciprocate and slide on the mounting plate 3. By pressing the upper limit block 701, the connecting column 703 and the lower limit block 702 are driven to move towards the groove 806, and the clamping block 804 is pushed into the interior of the groove 806 and separated from the clamping groove 303, and then the heat dissipation fan assembly 4 can be rotated.

[0028] The heat dissipation fan assembly 4 includes an annular housing 401, blades 402 and a driving member 403 arranged inside the annular housing 401. The driving member 403 is a motor that drives the blades 402 to rotate inside the annular housing 401. The connecting arm 5 is arranged at the top end of the annular housing 401. Through the cooperation of the heat dissipation fan and the radiator, the heat dissipation effect and efficiency are both higher.

[0029] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention falls within the protection scope of the present invention.
