Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Referring to fig. 1-6, the utility model discloses a run through usher's lamp before, includes:

a housing 400;

a light emitting assembly 100 disposed in the housing 400 and rotatably connected to the housing 400;

a driving assembly 500, including a driving screw 510 disposed on the housing 400, wherein the driving screw 510 is in threaded connection with the light emitting assembly 100, and the driving screw 510 is rotated to drive the light emitting assembly 100 to rotate relative to the housing 400.

The usher lamp in this application sets up the place ahead at the car together with driving light for launch usher's light. The light-emitting component 100 comprises a shell, a reflector and a PCB, wherein the reflector and the PCB are arranged inside the shell, a plurality of LED light sources are uniformly distributed on the PCB, the LED light sources emit light rays, and the light rays are reflected by the reflector to emit the light-emitting component 100, so that the function of illuminating a welcome guest is realized.

Specifically, set up drive screw 510 on casing 400, make drive screw 510 and light-emitting component 100 threaded connection, when rotating drive screw 510, light-emitting component 100 is driven and is rotated for casing 400, and then realizes light-emitting component 100's angle modulation, finally realizes the far and near gradual change regulation of usher's light, improves the visual effect and the use experience of preceding through-light.

It should be noted that the range of the angle adjustment required by the light emitting assembly 100 is very small, and the rotation speed of the motor is too fast and the amplitude is too large; if the light emitting assembly 100 is directly driven to rotate by the motor, it is difficult to precisely control the rotation angle, so that the distance light and the near light gradual change function of the light emitting assembly 100 cannot be realized.

Based on this, in the present application, in the form of the screw-thread connection with the light-emitting assembly 100 through the driving screw 510, when the driving screw 510 is rotated, the light-emitting assembly 100 has a tendency to move slowly along the axial direction of the driving screw 510 (when the driving screw 510 rotates once, the light-emitting assembly 100 has a tendency to move by one pitch); and because the light emitting assembly 100 is rotatably coupled to the housing 400, the tendency of the light emitting assembly 100 to move axially along the drive screw 510 is translated into a small degree of rotation relative to the housing 400. That is, the present application changes the movement form of the force by the screw connection of the driving screw 510 and the light emitting assembly 100, so that the rotation of the driving screw 510 is converted into the movement trend of the light emitting assembly 100, and then the movement trend is converted into the rotation of the light emitting assembly 100. Therefore, the movement speed is reduced, and the driving screw 510 can only rotate the light emitting assembly 100 by a small angle even if rotating by a large amplitude, so that the accurate control of the angle of the light emitting assembly 100 is realized, and the gradual change function of far and near light is realized.

Further, a fixing seat 530 is disposed on the light emitting assembly 100, a driving nut 520 is fixedly connected to the fixing seat 530, and the driving nut 520 is in threaded connection with the driving screw 510.

Specifically, the driving screw 510 is threadedly coupled to the driving nut 520, and when the driving screw 510 rotates, the driving nut 520 has a tendency to move along the axial direction of the driving screw 510, and the tendency drives the light emitting assembly 100 to rotate relative to the housing 400.

It should be noted that, in the present application, the driving nut 520 may be replaced by a connecting member having a thread and capable of being threadedly connected with the driving screw 510. Such as half the drive nut 520, a tube or ring with threads on the inner wall, etc.

Furthermore, the fixing seat can be fixedly connected to the light-emitting component and can also be rotatably connected to the light-emitting component. If the fixing base is rotatably connected to the light emitting component, when the light emitting component rotates relative to the shell, the fixing base and the light emitting component also rotate relatively, so that the fixing base cannot deform and is more durable. If the fixing base rigid coupling is on light emitting component, because the light emitting component pivoted range of this application is very little, consequently, light emitting component rotates and makes the produced deformation volume of fixing base be not enough to destroy the fixing base, and the produced deformation of fixing base can provide an elasticity moreover, and when needs reset, this elasticity can make light emitting component reset.

Further, the light emitting assembly 100 rotates relative to the housing 400 about a first rotation axis, which is a first straight line;

the axis of the driving screw 510 is a second straight line, and the second straight line is different from the first straight line.

First, it should be noted that the axial direction of the driving screw 510 is exactly the moving direction of the driving nut 520, and if the moving direction of the driving nut 520 is aligned with (intersecting with) the axis of the first rotating shaft, or the moving direction of the driving nut 520 is the same as (parallel to) the axial direction of the first rotating shaft, the trend of the driving nut 520 moving along the driving screw 510 cannot be converted into the rotation of the light emitting assembly 100.

Based on this, this application sets up first straight line and second straight line into the heterofacial straight line, and first straight line and second straight line are neither parallel nor intersect promptly, make drive nut 520 can drive light-emitting component 100 along the axial trend of moving of drive screw 510 and rotate, and then realize the angle modulation of light, realize the far and near gradual change function of usher's light.

Further, a driving motor 540 is further included and is fixed to the housing 400 and configured to drive the driving screw 510 to rotate.

Specifically, the output shaft of the driving motor 540 is connected to the driving screw 510 to drive the driving screw 510 to rotate, and further drive the light emitting assembly 100 to rotate.

Further, a first fixed seat 200 and a second fixed seat 300 are arranged in the housing 400;

one end of the light emitting assembly 100 is provided with a first connecting portion 110, and the first connecting portion 110 is rotatably connected to the first fixing base 200; a second connecting portion 120 is disposed at the other end of the light emitting assembly 100, and the second connecting portion 120 is rotatably connected to the second fixing base 300;

the first connecting portion 110 and the second connecting portion 120 are provided with barbs 130, and the barbs 130 abut against the first fixing seat 200/the second fixing seat 300 to limit the first connecting portion 110/the second connecting portion 120 from coming off the first fixing seat 200/the second fixing seat 300.

Specifically, the first fixing base 200 and the second fixing base 300 are both fixed on the housing 400, the first connecting portion 110 and the second connecting portion 120 are respectively disposed at two ends of the reflector, and the first connecting portion 110 is rotatably connected to the first fixing base 200, and the second connecting portion 120 is rotatably connected to the second fixing base 300, so that the angle adjustment of the light emitting assembly 100 is realized, and further, the height adjustment of the light is realized.

The present application provides barbs 130 on both the first connection portion 110 and the second connection portion 120. When the light emitting device 100 tends to fall off, the barb 130 abuts against the first fixing seat 200 or the second fixing seat 300 to prevent the light emitting device 100 from falling off, thereby preventing the light emitting device 100 from falling off.

Further, the first fixing base 200 is provided with a sliding groove 210, the first connecting portion 110 can slide into the first fixing base 200 along the sliding groove 210, and the first connecting portion 110 can rotate in the sliding groove 210;

the barb 130 abuts against the first fixing seat 200 to limit the first connecting portion 110 from sliding out of the sliding groove 210.

Specifically, the first connecting portion 110 has a sliding groove 210, so that the first connecting portion 110 slides into the first fixing base 200 along the sliding groove 210, thereby reducing the difficulty of mounting the light emitting assembly 100. Meanwhile, after the light emitting assembly 100 is installed, the barb 130 can abut against the first fixing seat 200, so that the anti-falling function is realized.

Further, the barb 130 includes a connecting section 131 and a limiting section 132, the connecting section 131 is perpendicular to the limiting section 132, and the connecting section 131 is fixedly connected to the first connecting portion 110;

the first fixing seat 200 includes a bottom plate 240 and two side plates 230, and the limiting section 132 abuts against the bottom plate 240 to limit the first connecting portion 110 to slide out of the sliding slot 210.

Furthermore, after the light emitting assembly 100 is installed, the limiting section 132 is located below the bottom plate 240 with a certain gap therebetween. In the rotating process of the light emitting assembly 100, if there is a tendency of upward separation, the limiting section 132 abuts against the bottom plate 240 after the light emitting assembly 100 moves upward by a small distance, so as to prevent the first connecting portion 110 from completely separating from the first fixing seat 200, thereby achieving the separation prevention effect.

The gap between the limiting section 132 and the bottom plate 240 is provided here, so that the light emitting assembly 100 can rotate freely after the light emitting assembly 100 is mounted, and the limiting section 132 and the bottom plate 240 are prevented from interfering with the rotation of the light emitting assembly 100.

Further, the chute 210 has an initial end and a terminal end, and the bottom plate 240 is at the terminal end;

the first connecting portion 110 can slide into the sliding groove 210 from the initial end and abut against the bottom plate 240;

the position-limiting section 132 abuts against the bottom plate 240 to limit the sliding of the first connecting portion 110 in the sliding slot 210 along the terminal end toward the initial end;

the first fixing base 200 further includes a back plate 220, and the two side plates 230 are fixedly connected with the back plate 220; one end of the side plate 230 away from the back plate 220 has a guiding surface 231, and the distance from the guiding surface 231 to the back plate 220 gradually increases from the initial end to the end.

Further, the barb 130 is made of an elastic material.

Further, the second fixing base 300 has a limiting hole therein, and the second connecting portion 120 can extend into the limiting hole and rotate in the limiting hole;

the second fixing base 300 is disposed in a circular ring shape, and a notch 310 allowing the second connecting portion 120 to pass through is formed on a side wall of the second fixing base 300;

the barb 130 abuts against or separates from the sidewall of the second fixing seat 300.

Specifically, the notch 310 is disposed on the sidewall of the second fixing base 300, so that the second connecting portion 120 can enter the limiting hole from the notch 310 at an inclined angle, and as the first connecting portion 110 is gradually pressed into the first fixing base 200, the second connecting portion 120 completely extends into the limiting hole.

It should be noted that, after the second connecting portion 120 completely extends into the limiting hole, the second connecting portion 120 cannot fall off from the second fixing base 300. However, after the light emitting assembly 100 is mounted, there may be a gap between the first connecting portion 110 and the back plate 220, and the light emitting assembly 100 may move laterally in the rotating process, so that the second connecting portion 120 exits from the limiting hole, and the second connecting portion 120 may be separated from the second fixing base 300.

Therefore, the barb 130 is also arranged on the second connecting portion 120, and even if the second connecting portion 120 moves transversely and retreats from the limiting hole, the barb 130 can abut against the second fixing seat 300 to prevent the second connecting portion 120 from separating from the second fixing seat 300, so that a secondary anti-falling effect is achieved.

The specific steps of mounting the light emitting assembly 100 in this embodiment are as follows: firstly, the second connecting part 120 partially extends into the second fixing base 300 at an inclined angle, and at the moment, the first connecting part 110 is positioned above the first fixing base 200, and the first connecting part 110 slides in along the initial end of the sliding groove 210; as the first connection portion 110 slides, the barb 130 abuts against the guide surface 231; the first connecting portion 110 continues to slide into the sliding groove 210, and the barb 130 generates a certain deformation; because the barb 130 is made of an elastic material, the barb 130 is gradually pressed into the sliding groove 210 along with the first connecting part 110 until the barb 130 passes through the bottom plate 240, and the original shape and position of the barb 130 are restored, so that the barb 130 is positioned below the bottom plate 240, and the anti-falling function is realized; meanwhile, as the first connecting portion 110 is gradually pressed into the first fixing base 200, the second connecting portion 120 completely enters the second fixing base 300, so that the light emitting assembly 100 is mounted.

In the installation process of the light emitting assembly 100, the two side plates 230 are provided with the guide surfaces 231, the guide surfaces 231 abut against the barbs 130, the barbs 130 are gradually deformed, the deformation of the barbs 130 is gradually increased, the force required by the first connecting portion 110 to press into the first fixing seat 200 is linearly increased gradually, and the process of the first connecting portion 110 being clamped into the first fixing seat 200 is smoother.

Moreover, the deformation process of the barb 130 is gradually increased along with the clamping depth, so that the required force is gradually increased, the situation that the force required for clamping is too large to control at the beginning is avoided, and the mounting difficulty is further reduced.
