[0024] The utility model is described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown, a single-cup low-beam rear direct-shooting headlight of the utility model comprises a direct-shooting high-beam light source 1, a first direct-shooting lens 2, a second direct-shooting lens 3, a third direct-shooting lens 4, a low-beam light source 5, a reflective cup 6 and a low-beam high-beam switching mechanism 7, wherein the first direct-shooting lens 2, the second direct-shooting lens 3 and the third direct-shooting lens 4 are all convex lenses.

[0026] The direct high beam light source 1, the first direct lens 2, the second direct lens 3 and the third direct lens 4 are arranged in a collinear manner, so that the direct high beam light source 1 is arranged at the rear of the headlight, which solves the problem of the direct high beam light source 1 occupying the upper space of the headlight and makes the internal space of the headlight more reasonable.

[0027] The reflective cup 6 is arranged between the second direct lens 3 and the third direct lens 4 and is located in the upper half of the third direct lens 4, the low beam light source 5 is arranged below the reflective cup 6, and the low beam and high beam switching mechanism 7 is arranged between the reflective cup 6 and the third direct lens 4 and is located in the lower half of the third direct lens 4.

[0028] When using, Figure 2As shown, the low beam light source 5 is powered on to emit low beam light, which is reflected by the reflector cup 6 to the third direct lens 4. The low beam light is refracted by the third direct lens 4 to illuminate the short distance, so that the vehicle lamp is in low beam lighting mode.

[0029] like Figure 3 As shown, the direct high-beam light source 1 is powered on to emit high-beam light, which is expanded in irradiation angle by the first direct lens 2 and the second direct lens 3, and then refracted by the third direct lens 4 for short-distance and long-distance illumination, so that the vehicle lamp is in high-beam illumination mode.

[0030] like Figure 4 As shown, the low-beam high-beam switching mechanism 7 blocks the high-beam light from irradiating the lower half of the third direct lens 4, so that the high-beam light is refracted by the upper half of the third direct lens 4 to irradiate the ground, increasing the brightness of the short-distance lighting, and making the headlights in the low-beam lighting supplementary mode. This avoids irradiating distant vehicles and pedestrians, and solves the contradiction that the high-beam light emitted by the direct high-beam light source 1 cannot supplement the short-distance lighting.

[0031] The low-beam and high-beam switching mechanism 7 avoids the high-beam light from irradiating the lower half of the third direct lens 4, so that the vehicle lamp switches to high-beam lighting, so that the vehicle lamp can realize the switching between low-beam lighting and high-beam lighting.

[0032] like Figure 5 As shown, the reflective cup 6 of this embodiment includes a fixing portion 61 and a reflecting portion 62. The fixing portion 61 is disposed on both sides of the reflecting portion 62, and the reflective cup 6 is conveniently fixed by the fixing portion 61. The reflecting portion 62 is provided with a first light through hole 621 and a second light through hole 622, the first light through hole 621 is disposed on one side of the second direct lens 3, and the second light through hole 622 is disposed on one side of the third direct lens 4.

[0033] When in use, the high beam light emitted by the direct high beam light source 1 is powered on and passes through the first direct lens 2 , the first light opening 621 , and the second light opening 622 to irradiate the second direct lens 3 .

[0034] The reflective portion 62 of this embodiment is elliptical. A first cutting portion 63 and a second cutting portion 64 are disposed on one side of the reflective portion 62 close to the second light opening 622 . The first cutting portion 63 is disposed on the upper portion of the second cutting portion 64 .

[0035] The low beam light source 5 is powered on to emit low beam light which is reflected by the reflector cup 6 and then irradiated to the third direct lens 4 by the first cutting portion 63 and the second cutting portion 64 . The first cutting portion 63 and the second cutting portion 64 reduce the interference of the second light opening 622 on the light.

[0036] The diameter of the first light opening 621 of this embodiment is smaller than that of the second light opening 622 , so that the high beam light can pass through the reflective portion 62 after the first direct lens 2 and the second direct lens 3 expand the irradiation angle.

[0037] In this embodiment, a first connection portion 611 connected to the reflection portion 62 is disposed inside the fixing portion 61 , and the fixing portion 61 is fixed to the reflection portion 62 via the first connection portion 611 .

[0038] The fixing portion 61 is provided with a fixing clamping portion 612 on the outside thereof, and the fixing portion 61 is fixed by the fixing clamping portion 612, thereby fixing the reflective cup 6. The fixing portion 61 is provided with a fixing hole 613 on the inside thereof, and the reflective cup 6 is fixed by the fixing hole 613.

[0039] The fixed clamping portion 612 of this embodiment includes a first clamping straight edge 6121, a second clamping straight edge 6122, a first clamping arc edge 6123, a third clamping straight edge 6124, a second clamping arc edge 6125, and a fourth clamping straight edge 6126, which are connected in sequence. The first clamping straight edge 6121, the second clamping straight edge 6122, the first clamping arc edge 6123, the third clamping straight edge 6124, the second clamping arc edge 6125, and the fourth clamping straight edge 6126 facilitate the fixing of the fixed clamping portion 612.

[0040] The low-beam and high-beam switching mechanism 7 of this embodiment includes a driver 71 and a shielding member 72 . The driver 71 may be an electric cylinder or a linear motor.

[0041] The driver 71 drives the shielding member 72 to rise or fall. When the driver 71 drives the shielding member 72 to rise, the low-beam and high-beam switching mechanism 7 blocks the high-beam light from irradiating the lower half of the third direct lens 4 .

[0042] When the driver 71 drives the shielding member 72 to descend, the low-beam and high-beam switching mechanism 7 prevents the high-beam light from irradiating the lower half of the third direct lens 4 .

[0043] The shielding member 72 of this embodiment includes a convex arc surface 721 and a concave arc surface 722 , and the convex arc surface 721 faces one side of the reflective cup 6 . When the driver 71 drives the shielding member 72 to rise, the shielding member 72 shields the high beam light through the convex arc surface 721 .

[0044] The first direct lens 2, the second direct lens 3 and the third direct lens 4 of this embodiment all include a light-transmitting mounting portion 41 and a light-transmitting refracting portion 42, and the light-transmitting mounting portion 41 and the light-transmitting refracting portion 42 are integrally formed. The light-transmitting mounting portion 41 facilitates fixing the first direct lens 2, the second direct lens 3 and the third direct lens 4. The light-transmitting refracting portion 42 enables the first direct lens 2, the second direct lens 3 and the third direct lens 4 to refract light.

[0045] In this embodiment, the diameter of the first direct lens 2 is less than the diameter of the second direct lens 3 and less than the diameter of the third direct lens 4. The first direct lens 2, the second direct lens 3 and the third direct lens 4 can expand the irradiation angle and refract the light.

[0046] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
