[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0026] The driving route indicator provided by this utility model includes a housing, a light source, a light guide strip, and a drive assembly. The housing is fixed to the front end of the vehicle, and the light source, light guide strip, and drive assembly are all housed within the housing. The light source is located on the rear side of the housing and is used to emit laser light forward, for example, a laser generator. The front surface of the housing forms a light-transmitting surface, which is inclined at a predetermined angle towards the ground. The light guide strip has a predetermined height, and one end (rear end) of the light guide strip is positioned opposite the light source as the light input end; the other end (front end) of the light guide strip serves as the light output end and extends to the light output surface on the front side of the housing. Thus, when the light source is lit, the laser light emitted from the light source can be transmitted through the light guide strip to the light output surface on the front side of the housing, and projected onto the road ahead through the light output surface, forming a long strip of illumination projection to facilitate the driver's observation of the road conditions ahead. Simultaneously, the light guide strip is flexible, and the light output end of the light guide strip is connected to the drive end of the drive assembly, allowing it to bend synchronously with the steering of the vehicle's front wheels under the drive of the drive assembly. In other words, when the front wheels of the vehicle turn left, causing the vehicle to turn left, the light guide strip can also bend to the left, so that the resulting lighting projection is an arc with the front end bending to the left, thereby illuminating the road on the left side in front of the vehicle; when the front wheels of the vehicle turn right, causing the vehicle to turn right, the light guide strip can also bend to the right, so that the resulting lighting projection is an arc with the front end bending to the right, thereby illuminating the road on the right side in front of the vehicle.
[0027] Therefore, the route indicator of this application can form an illuminated projection on the vehicle's route according to the steering of the vehicle's front wheels, so as to indicate the route and make it easier for the driver to see the road conditions ahead and avoid accidents.
[0028] This utility model also provides a tractor that includes the aforementioned route indicator, thus the tractor also has the beneficial effects of a route indicator. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0040] The following reference Figures 1 to 3 This application describes a route indicator and a tractor according to some embodiments thereof.
[0041] This application provides a route indicator for installation on the front of a vehicle (such as a tractor). It should be noted that the front-back, left-right, and up-down directions referred to in this application are consistent with the front-back, left-right, and up-down directions of the vehicle coordinate system when the route indicator is installed on the vehicle.
[0042] like Figures 1 to 3 As shown, the route indicator includes a housing 1, a light source 2, a light guide strip 4, and a drive assembly. The housing 1 is fixed to the front of the vehicle. The light source 2, light guide strip 4, and drive assembly are all housed inside the housing 1. The light source 2 is located on the rear side of the housing 1 and is used to emit laser light forward; for example, the light source 2 is a laser generator. The front surface 9 of the housing 1 forms a light-transmitting surface, which is tilted towards the ground at a predetermined angle. The light guide strip 4 has a predetermined height, and one end (rear end) of the light guide strip 4 is positioned opposite the light source 2 as the light input end; the other end (front end) of the light guide strip 4 serves as the light output end and extends to the light output surface on the front side of the housing 1. Thus, when the light source 2 is lit, the laser light emitted by the light source 2 can be transmitted through the light guide strip 4 to the light output surface on the front side of the housing 1 and projected onto the road ahead, forming a long strip of illumination projection to facilitate the driver's observation of the road conditions ahead.
[0043] Meanwhile, the light guide strip 4 is flexible, and its light-emitting end is connected to the driving end of the drive assembly, so that it can bend synchronously with the steering of the vehicle's front wheels under the drive of the drive assembly. That is, when the vehicle's front wheels turn left, causing the vehicle to turn left, the light guide strip 4 can also bend to the left, so that the resulting illumination projection is an arc shape with the front end bending to the left, thereby illuminating the road on the left side in front of the vehicle; when the vehicle's front wheels turn right, causing the vehicle to turn right, the light guide strip 4 can also bend to the right, so that the resulting illumination projection is an arc shape with the front end bending to the right, thereby illuminating the road on the right side in front of the vehicle.
[0044] Therefore, the route indicator of this application can form an illuminated projection on the vehicle's route according to the steering of the vehicle's front wheels, so as to indicate the route and make it easier for the driver to see the road conditions ahead and avoid accidents.
[0045] In this embodiment, preferably, as follows: Figure 2 and Figure 3 As shown, the light guide strip 4 has a predetermined height in the vehicle height direction (i.e., the vertical direction), and the vertical cross-section formed by the light guide strip 4 in the left and right directions is an arrowhead shape with the arrow pointing upwards, so that the illumination projection formed on the ground is an arrowhead shape with the arrow pointing forward.
[0046] In one embodiment of this application, preferably, as shown below, Figure 2 As shown, the driving assembly includes a first driving member 5; the light guide strip 4 has a top at the upper end and a bottom at the lower end along the height direction of the vehicle, and the bottom of the light guide strip 4 is fixedly installed. The driving end of the first driving member 5 is connected to the top of the light-emitting end of the light guide strip 4 so as to provide a driving force for the light guide strip 4 to bend to the left through the first driving member 5.
[0047] In this embodiment, preferably, as follows: Figure 2 As shown, the driving assembly also includes a second driving member 6, the driving end of which is also connected to the top of the light-emitting end of the light guide strip 4, so as to provide a rightward bending driving force to the light guide strip 4 through the second driving member 6.
[0048] In this embodiment, preferably, as follows: Figure 2 As shown, the driving assembly also includes a pull wire 7, a first pulley, and a second pulley. Both the first and second pulleys are mounted on the front surface 9 of the housing 1, with the first pulley located on the left side of the front surface 9 and the second pulley located on the right side. One end of the pull wire 7 passes over the first pulley and connects to the driving end of the first driving member 5, while the other end passes over the second pulley and connects to the driving end of the second driving member 6. Simultaneously, a fixing block is provided at the top of the light-emitting end of the light guide strip 4, and the fixing block is connected to the pull wire 7. The first driving member 5 can pull the pull wire 7 to the left, thereby bending the top of the light guide strip 4 to the left. The second driving member 6 can pull the pull wire 7 to the right, thereby bending the top of the light guide strip 4 to the right.
[0049] In this embodiment, preferably, the first driving member 5 is an elastic member, the second driving member 6 is a drive motor, the driving end of the second driving member 6 is provided with a spool, and the end of the pull wire 7 facing the second driving member 6 is wound on the spool. The second driving member 6 can drive the spool to rotate so as to wind or release the pull wire 7.
[0050] In practical operation, when the light guide strip 4 is in an upright, unbent state, the elastic element is in a stretched state, and the elastic force of the elastic element is balanced with the force exerted on the pull wire 7 by the second driving element 6. When the light guide strip 4 needs to bend to the right, the second driving element 6 can overcome the elastic force of the elastic element and continue to wind up the pull wire 7. When the light guide strip 4 needs to bend to the right, the second driving element 6 releases the pull wire 7, and the elastic force of the elastic element can pull the pull wire 7 to make the light guide strip 4 bend to the left.

The first side wall, the second side wall, and the top wall interact with each other, and the top of the light guide strip 4 can be bent to the left against the top wall to abut against the first side wall, or bent to the right to abut against the second side wall.
[0052] In this embodiment, preferably, as follows: Figure 3 As shown, a through hole is provided on the front surface 9 of the housing 1 within the space formed by the light-blocking wall 8, and a light-transmitting protective plate 10 is installed at the through hole. The light-transmitting protective plate 10 forms a light-emitting surface on the front surface 9 of the housing 1.
[0053] In this embodiment, preferably, as follows: Figure 2 As shown, a light-shielding plate 3 is provided inside the housing 1. The light-shielding plate 3 divides the interior of the housing 1 into two chambers, front and rear. The chamber located on the rear side is the first chamber, and the chamber located on the front side is the second chamber. The light source 2 is installed in the first chamber, and the light-shielding plate 3 has a mounting hole at the position opposite to the light source 2. The light-inlet end of the light guide strip 4 is embedded in the mounting hole, thereby ensuring that the laser emitted by the light source 2 propagates forward through the light guide strip 4.
[0054] This application also provides a tractor that includes a route indicator according to any of the above embodiments.
[0055] In this embodiment, the tractor includes a route indicator, and therefore the tractor has all the beneficial effects of a route indicator, which will not be described in detail here.
[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
