Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle lamps, and specifically relates to an LED vehicle headlamp with an anti-loosening function. Background Art

[0002] In the prior art, such as Figure 1 As shown, the LED car headlight is fixed together with components such as radiator 1 4, radiator 2 8, copper substrate 7 for mounting LED 6, fan 10, fan cover 11, mounting ring 1, sealing ring 2, wire 5 by screws 3. Usually, fan 10 is covered by fan cover 11 to form a stable air duct to improve the heat dissipation effect of the product.

[0003] Since the fan cover 11 and the radiator 1 4 and the radiator 2 8 are mostly assembled by interference fit, this kind of fit is prone to looseness in high and low temperature environments and severe vibration conditions, thereby causing premature failure of the product; at the same time, the interference fit requires strict control of the interference amount, otherwise it will cause problems such as inability to assemble or loose fit, thus placing higher requirements on processing accuracy, increasing processing difficulty, reducing yield, and raising manufacturing costs. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an LED car headlight with an anti-loosening function, which is used to solve the problem that the interference fit between the fan cover and the radiator in the prior art is prone to loosening, affecting the use of the product, and at the same time requires strict control of the interference amount and high requirements for processing precision.

[0005] The technical solutions adopted in this application are as follows:

[0006] This solution provides an LED automobile headlight with an anti-loosening function, including:

[0007] The radiator 1 and the radiator 2 are processed into reverse serrated structures, the fan cover is equipped with opposite tooth shapes, and the mouth of the fan cover is processed into chamfers with the same slope. After the fan cover and the radiator 1 and the radiator 2 are pressed into fit, a snap-fit ​​is formed, and a snap fit with an H depth is set, which can remain fixed at higher or lower temperatures, and can also withstand vibration shocks of larger amplitude and frequency without loosening.

[0008] Furthermore, it also includes a limiting ring, on which a slot for fixing the copper substrate is opened. The limiting ring is installed at the openings of the radiator 1 and the radiator 2, further increasing the stability of the structural connection.

[0009] The beneficial effects achieved by the utility model using the above structure are as follows:

[0010] After the fan cover is pressed into fit with the radiator 1 and the radiator 2, a buckle fit is formed, and a buckle with an H depth is set, which can remain fixed at higher or lower temperatures, and can withstand vibration shocks of greater amplitude and frequency without loosening, effectively improving the reliability and stability of the product, thereby ensuring the effective life of the LED car light product.
