Description

TECHNICAL FIELD

[0001] The present application belongs to the field of vehicle lighting devices and vehicle technology, and particularly relates to a vehicle lamp and a vehicle, in particular to a headlamp capable of adjusting light beam focusing and divergence and a vehicle provided with the headlamp. BACKGROUND

[0002] In the field of vehicle lighting, the light beam distribution and irradiation range of a vehicle lamp are directly related to driving safety and driving experience. A conventional vehicle lamp system usually adjusts the position of a lens, a reflector or a light shield through a mechanical or electronic actuator (such as a motor, a stepper motor or an electromagnetic actuator) to realize switching between high beam and low beam or adjusting the local illumination range. Most vehicle lamps in the prior art only support limited preset illumination modes (such as high-low angle adjustment) and cannot dynamically respond to real-time requirements for light beam divergence and focusing due to changes in vehicle speed.

[0003] The prior art has obvious deficiencies in terms of speed-adaptive lighting requirements. When driving at low speed (such as on urban roads or in a passing scene), the driver needs the light beam of the vehicle lamp to be more divergent to expand the lateral irradiation range and avoid dazzling the driver of an oncoming vehicle. When driving at high speed, the light beam needs to be highly focused to improve the long-distance irradiation capability and ensure early identification of obstacles. Current solutions mostly rely on manual switching of the driver or changing the light beam projection angle through a simple high-low adjustment mechanism, but such methods cannot realize continuous dynamic adjustment of the divergence and focusing of the light beam, and manual operation is likely to distract the driver's attention. SUMMARY

[0004] The present application provides a vehicle lamp and a vehicle which can automatically and continuously dynamically adjust the focusing degree of the vehicle lamp according to the vehicle speed without human operation, and has a simple structure, low cost and no risk of electronic control failure.

[0005] In order to solve the above technical problems, the present application is solved by the following technical scheme: a car lamp, comprising a car lamp body, a supporting part is arranged in the car lamp body, a light emitting unit is arranged on the supporting part, a reflector is arranged above the light emitting unit, a wind channel is arranged through the car lamp body, a guide hole is arranged on the side wall of the wind channel and faces the reflector, the reflector is a hard elastic reflector, a guide rod is arranged on the top of the reflector and movably arranged in the guide hole, a spring is sleeved on the guide rod, the two ends of the spring abut against the outer wall of the reflector and the outer wall of the wind channel respectively, the reflector is deformed and expanded on both sides under the pressure of the spring, a wind blocking assembly is arranged in the wind channel, the guide rod is connected with the wind blocking assembly through a cable, the wind blocking assembly can be pushed and moved or rotated by the airflow in the wind channel to pull the guide rod to lift, and the reflector is gradually focused when the guide rod is lifted. When the vehicle runs at low speed, the airflow can pass through the wind channel, but the wind blocking assembly cannot be pushed and rotated, the reflector is bent by the spring and expanded on both sides, so that the light emitted by the light emitting unit is divergent, and the oncoming vehicle is not dazzled; during the process that the vehicle gradually increases the running speed, the airflow can pass through the wind channel and push the wind blocking assembly to move or rotate, the guide rod is lifted through the cable during the movement or rotation of the wind blocking assembly, the faster the vehicle runs, the greater the amplitude of the movement or rotation of the wind blocking assembly, the reflector is restored due to the elastic force and the tension of the cable, and the focusing degree is gradually increased, so that the light is gradually focused with the increase of the vehicle speed, thereby the focusing degree can be automatically and continuously dynamically adjusted according to the vehicle speed without manual operation, the structure is simple, the cost is low, and there is no worry about the failure of electronic control.

[0006] In the above technical scheme, preferably, the reflector is made of spring steel, and the inner wall of the reflector is coated with a reflective coating. Since the spring steel has high elastic modulus and excellent fatigue resistance, it is suitable as the material of the reflector in the present application, and meets the long-term repeated expansion and contraction operation.

[0007] In the above technical scheme, preferably, the reflector is in the original state of a quarter ellipsoidal shell. The structure makes the reflector have better focusing degree when it is restored.

[0008] In the technical scheme, preferably, the light-emitting unit is arranged on the movable plate, the movable plate is provided with an inclined hole, the light reflector is provided with a driving arm at the bottom of both sides, the driving arm extends into the inclined hole, when the light reflector is folded, the driving arm pushes the side wall of the inclined hole to drive the movable plate to move, when the light reflector restores to the quarter-ellipsoid shell shape, the light-emitting unit moves to the focal point of the quarter-ellipsoid shell. The structure can drive the light-emitting unit on the movable plate to move when the light reflector expands and contracts. When the vehicle speed is low, the light-emitting unit is away from the focal point, the light divergence effect is better, and the oncoming vehicle is not dazzled. When the vehicle speed gradually increases, the light-emitting unit gradually approaches the focal point. When the guide rod is lifted to the highest position, the light-emitting unit returns to the focal point, and the light focusing degree is better.

[0009] In the technical scheme, preferably, the light reflector is fixed on the support part, and a gap for the movable plate to move is formed between the light reflector and the support part.

[0010] In the technical scheme, preferably, the guide rod is provided with a limiting part outside the periphery for limiting the highest lifting position of the guide rod, and when the guide rod is lifted to the highest position, the light reflector restores to the quarter-ellipsoid shell shape. The structure can make the light reflector restore to the quarter-ellipsoid shell shape when the vehicle speed reaches a certain speed. Due to the limiting of the limiting part, the guide rod cannot be lifted again, so that the light reflector remains in the quarter-ellipsoid shell shape with the best focusing degree when the vehicle speed exceeds the certain speed.

[0011] In the technical scheme, preferably, the support part is provided with at least two limiting nails for limiting the up-down movement of the movable plate, the movable plate is provided with a waist hole in the moving direction of the movable plate, and the limiting nail moves in the waist hole when the movable plate moves. The structure can avoid the up-down movement and swinging of the movable plate. The movable plate can only move in the direction of the waist hole, so that the operation of the light reflector expansion and contraction driving the movable plate to move is more stable.

[0012] In the technical scheme, preferably, the wind-blocking assembly includes an elastic inclined plate fixed on the top of the air duct and obliquely blocking the air duct, and the elastic inclined plate is connected with the guide rod through the cable. The elastic inclined plate can almost completely open the air duct when the wind force in the air duct is large, effectively avoiding the accumulation of sundries in the air duct.

[0013] In the technical scheme, preferably, the wind-blocking assembly includes a movable plug slidingly arranged in the air duct and matched with the shape of the air duct, and the movable plug is provided with a ventilation hole.

[0014] A vehicle provided with the vehicle lamp, the front face of the vehicle is provided with an air inlet, the side or bottom of the vehicle is provided with an air outlet, the air inlet is connected with the air inlet side of the air duct through a ventilation pipe, and the air outlet is connected with the air outlet side of the air duct through a ventilation pipe. With this structure, the vehicle can cooperate with the vehicle lamp to supply the air volume in the air duct, so that the air duct in the vehicle lamp can have larger air volume when the vehicle speed is faster, and smaller air volume when the vehicle speed is slower. The focusing degree of the vehicle lamp is automatically and continuously dynamically adjusted according to the vehicle speed, without the worry of electronic control failure.

[0015] Compared with the prior art, the vehicle lamp and the vehicle have the following beneficial effects: when the vehicle travels at low speed, the airflow can pass through the air duct, but the wind shield assembly is not pushed or rotated, the reflector is bent by the spring, and the two sides of the profile, so that the light emitted by the light emitting unit is divergent, avoiding dazzling the oncoming vehicle; during the process that the vehicle driving speed gradually increases, the airflow can pass through the air duct, push the wind shield assembly to move or rotate, and the guide rod is lifted through the cable during the movement or rotation of the wind shield assembly. The faster the vehicle speed, the greater the amplitude of the movement or rotation of the wind shield assembly, the reflector is restored due to the elastic force of itself and the tension of the cable, the focusing degree is gradually increased, and the light is gradually focused with the increase of the vehicle speed, so that the focusing degree is automatically and continuously dynamically adjusted according to the vehicle speed without manual operation, the structure is simple, the cost is low, and there is no worry of electronic control failure.
