Description

Headlight

The invention relates to a vehicle lamp, in particular to a lamp with a projection type near and far lamp switching effect.

In order to meet different road conditions and line-of-sight requirements, the Poly-Ellipsoid System (PES) lights currently installed in front of motor vehicles such as steam and locomotives have a mode design that can control the switching between far and near lights. As shown in FIG. 1 , a conventional lamp 1 includes a hollow base 11 , a lamp cover 12 disposed on the front side of the base 11 , and a light-emitting member 13 mounted on the base 11 and capable of emitting light. a visor 14 positioned in front of the illuminating member 13, a pivot 15 for pivotally mounting the visor 14 in the pedestal 11, and a solenoid valve controllable to drive the visor 14 16. The visor 14 has a pivoting portion 141 for mounting the shaft 15, a blocking portion 142 extending upward from the pivoting portion 141 and located in front of the illuminating member 13, and a pivoting portion 141 The push portion 143 extends downwardly and is coupled to the solenoid valve 16.

In use, when the electromagnetic valve 16 is not actuated, the visor 14 is not yawed and stands in front of the illuminating member 13, and the light of the illuminating member 13 is shielded from the illuminating member 14 by the light shielding of the illuminating member 14 After the action, the forward projected light has a near-light effect. When the solenoid valve 16 pushes the pushed portion 143 of the visor 14 forward, the visor 14 is centered on the shaft 15 and is swiveled at an angle with respect to the susceptor 11 in the direction indicated by the arrow 17 ( As shown by the imaginary line in the figure, the light projected forward by the illuminating member 13 will have a far-light effect.

It can be seen from the above that the electromagnetic valve 16 drives the visor 14 to yaw, so that the light emitted by the illuminating member 13 is blocked by different degrees, and the size of the light projection area can be changed to achieve the switching between the far and the near lights. The effect is that, since the above-mentioned light lamp 1 causes the electromagnetic valve 16 to directly yaw the visor 14 , the electromagnetic valve is determined under the relative relationship between the visor 14 , the shaft 15 and the electromagnetic valve 16 . 16 needs to move a long distance to push the visor 14 to move by a predetermined angle. For example, it is necessary to push 2 mm forward to make the visor 14 rotate clockwise by 4°, which will drag the switch between the far and the near lights. The speed will also occupy the internal space of the lamp 1 so that the volume of the lamp 1 is difficult to reduce, so the above design still needs to be improved.

Accordingly, it is an object of the present invention to provide a vehicle lamp that can quickly switch between near and near lighting effects.

Thus, the lamp of the present invention comprises: a lamp holder unit, a lighting unit, a shading unit, and a driving unit. The base unit includes a base and a light cover disposed on the front side of the base, the base and the cover together define a projection space. The lighting unit includes a lighting member mounted on the base and capable of emitting light. The light shielding unit includes a light shielding plate positioned in the projection space, a light shielding shaft that swings the light shielding plate in front of the light emitting member, and a linkage rod that drives the light shielding plate to swing, the linkage rod Having a connecting portion corresponding to the light-shielding rod and movably engaging the visor, a pushing portion away from the connecting portion, and a position between the connecting portion and the pushed portion and pivoted a linkage pivoting portion in front of the visor. The driving unit includes a solenoid valve that can drive the pushing portion of the linkage rod, and the electromagnetic valve can be controlled to drive the light shielding unit relative to the socket unit, and the electromagnetic valve does not push the linkage rod to make the shading The plate is vertically erected in a position near the lamp in front of the illuminating member, and a solenoid valve pushes the linking rod forward to drive the visor to switch between the tilting positions of the illuminating member.

The utility model has the advantages that: by the setting of the linkage rod, when the electromagnetic valve is actuated, the linkage lever and the visor are interlocked to greatly change the moving position of the visor, so as to achieve fast switching distance, The advantage of the near light effect.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

Referring to FIG. 2 and FIG. 3, a preferred embodiment of the vehicle lamp of the present invention is mounted on the front side of a motor vehicle (not shown) such as a steam, a locomotive, etc., and can project near or far lights in different states, and includes: The lamp holder unit 2, an illumination unit 3, a shading unit 4, and a drive unit 5. Of course, the present invention further includes a casing (not shown) disposed on the front side of the motor vehicle and mounted to the unit, and a casing (not shown). Since the component is not the focus of the present invention, it is no longer Detailed description.

The socket unit 2 includes a base 21 and a lamp cover 22 that is transparent and disposed on the front side of the base 21. The base 21 and the shade 22 together define a projection space 23. The susceptor 21 is a reflector that reflects light on the inner peripheral surface.

The light emitting unit 3 includes a light emitting member 31 horizontally mounted on the base 21 and capable of emitting light. The lighting unit 3 further includes some connecting circuits and other components in the implementation, but it is not the focus of the present invention, so it will not be described in detail herein.

The light shielding unit 4 includes a light shielding plate 41 positioned in the projection space 23, a light shielding shaft 42 that swings the light shielding plate 41 in front of the light emitting member 31, and a light shielding shaft 41 that swings the light shielding plate 41. The linkage rod 43 and a linkage shaft 44 pivotally pivoting the linkage rod 43 in front of the light shielding plate 41.

The visor 41 has a light-shielding pivoting portion 411, a shielding portion 412 extending upward from the light-shielding pivoting portion 411 and located in front of the illuminating member 31, and a protruding hook extending from the shielding portion 412 toward the front hook Part 413. The light shielding shaft 42 is attached to the light shielding pivot portion 411 of the light shielding plate 41. The linkage rod 43 has a connecting portion 431 corresponding to the light-shielding rod 42 and movably coupled to the protruding portion 413, a pushed portion 432 away from the connecting portion 431, and a position at the connecting portion 431 The interlocking pivot portion 433 is connected to the pushed portion 432. The pushed portion 432 is located below the interlocking pivot portion 433 and the connecting portion 431. The interlocking shaft 44 is located in front of the light shielding shaft 42 and is attached to the interlocking pivoting portion 433 of the linkage rod 43.

The drive unit 5 includes a solenoid valve 51 that can drive the pushed portion 432 of the linkage rod 43. The solenoid valve 51 has a valve seat 511 and a valve stem 512 that movably projects horizontally forward from the front side of the valve seat 511 and engages the pushed portion 432. Of course, the driving unit 5 further includes other driving members and fixing members, but it is not the focus of the present invention, so it will not be described in detail herein.

In use, the solenoid valve 51 can be controlled to drive the shading unit 4 relative to the base unit 2 in a near lamp position (see the solid line state of FIG. 3) and a high beam position (see the imaginary line of FIG. 3). Switch between states). As shown in the solid line state of FIG. 3, in the near-light position, the solenoid valve 51 is not energized, so the linkage rod 43 is not pushed, and the shutter 41 is vertically erected in front of the light-emitting member 31. The light emitted by the illuminating member 31 is blocked by the visor 41 and reflected by the susceptor 21, so that the projected light path is biased downward to exhibit a near-light mode.

When the switch is to be switched to the remote position, the solenoid valve 51 can be energized to activate the solenoid valve 51. As shown in the imaginary line state of FIG. 3, the valve stem 512 protrudes forward to push the push portion 432 of the linkage rod 43. The interlocking lever 43 is pivoted around the interlocking shaft 44 to push the shielding portion 412, and the light shielding plate 41 is swung in the direction indicated by the arrow 6 around the light shielding shaft 42 so that the shielding portion 412 is oriented. The illuminating member 31 is tilted at an angle to the position of the remote lamp. At this time, the light emitted by the illuminating member 31 is partially blocked by the visor 41 and reflected by the pedestal 21, and the area where the light is shielded is smaller than the above. The position of the lamp is such that the projected light path is straight and far, showing a high light mode.

It should be noted that the lamp may further include a reset unit (not shown) installed between the base unit 2 and the shading unit 4, the reset unit including at least one elastic member (not shown). When the light shielding unit 4 is switched from the near lamp position to the remote lamp position, the elastic member is twisted to accumulate an elastic restoring force, so when the electromagnetic valve 51 is no longer energized, the elastic member releases its elastic reset. The force, and the shutter unit 4 is rotated to the near lamp position to cooperate with the electromagnetic valve 51 to achieve the purpose of switching between the far and the near lights, but it is a general design, so it will not be redundant.

In summary, the vehicular lamp of the present invention is mainly between the visor 41 and the electromagnetic valve 51, and is movably coupled to the linkage rod 43 to increase the solenoid valve by the linkage yaw of the linkage rod 43. The actuating relationship between the 51 and the visor 41 causes the solenoid valve 51 to push only a small distance forward, thereby greatly changing the position of the visor 41, for example, when the solenoid valve 51 is pushed forward 2 mm as is conventional. When the visor 41 is swung 11°, which is larger than the conventional 4°, it can be seen that if the visor 41 reaches the yaw angle specified by the vehicle, the solenoid valve 51 only needs to move shorter than The conventional distance can be changed, and the state in which the visor 41 shields the light can be quickly changed, and the feature of quickly switching between the far and the near light effects can be achieved. The present invention can relatively reduce the volume, so that the object of the present invention can be achieved.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
