Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a vehicle arrow warning system. Background Technology

[0002] As core equipment in construction engineering, engineering vehicles are widely used in earthwork transportation, foundation excavation, road repair, and special operation scenarios. Their mechanized operation mode significantly improves construction efficiency and reduces labor costs. To ensure operational safety, existing engineering vehicles generally integrate fixed arrow light groups at the rear, which simultaneously indicate to vehicles behind to pass around the sides of the engineering vehicle via arrows on both sides.

[0003] However, traditional arrow light systems have significant technical limitations: their direction remains static during vehicle operations and cannot be dynamically adjusted according to real-time road conditions. When a lane on one side of the work area is blocked due to construction obstacles, road damage, or unforeseen circumstances, the arrow light continuously pointing to the restricted lane will send incorrect traffic signals to following vehicles, causing them to mistakenly enter the restricted area. This technical limitation easily leads to traffic accidents, exposing the insufficient adaptability of traditional mechanical warning devices in complex working conditions.

[0004] Therefore, there is an urgent need for vehicle-mounted arrow warning systems to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a vehicle arrow warning system to solve the problem that traditional arrow light systems keep the direction of the vehicle's indication static and fixed during vehicle operation, and cannot be dynamically adjusted according to real-time road traffic conditions, resulting in insufficient adaptability in complex working conditions.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0045] like Figures 1 to 7As shown, this embodiment provides a vehicle arrow warning system, which includes an arrow indicator light group 1 and a bracket mechanism 2. The arrow indicator light group 1 includes a first arrow light 11 and a second arrow light 12. The bracket mechanism 2 is configured to be fixed to the rear of the vehicle 100. The arrow indicator light group 1 is disposed on the bracket mechanism 2. The first arrow light 11 and the second arrow light 12 are spaced apart along the vehicle width direction Y. The bracket mechanism 2 can drive the first arrow light 11 to a first position a and a second position a. At the first position a, the first arrow light 11 points away from the second arrow light 12 along the vehicle width direction Y. At the second position a, the first arrow light 11 points closer to the second arrow light 12 or along the vehicle height direction Z along the vehicle width direction Y. The bracket mechanism 2 can drive the second arrow light 12 to a first position b and a second position b. At the first position b, the second arrow light 12 points away from the first arrow light 11 along the vehicle width direction Y. At the second position b, the second arrow light 12 points closer to the first arrow light 11 or along the vehicle height direction Z along the vehicle width direction Y. When the vehicle 100 equipped with the vehicle arrow warning system is in operation, and both sides of the vehicle 100 are passable, the support mechanism 2 switches the first arrow light 11 to the first position a, pointing away from the second arrow light 12, and switches the second arrow light 12 to the second position b, pointing away from the first arrow light 11. At this time, the vehicle arrow warning system indicates that the following vehicle 100 can pass through the roads on either side of the vehicle 100. When the road indicated by the first arrow light 11 is not passable, the support mechanism 2 switches the first arrow light 11 to the second position a. At this time, the first arrow light 11 can point in the same direction as the second arrow light 12, or it can point vertically, so that the vehicle arrow warning system indicates that the following vehicle 100 can pass through the road on the side indicated by the second arrow light 12. Similarly, when the road indicated by the second arrow light 12 is impassable, the support mechanism 2 switches the second arrow light 12 to the second position b. At this time, the second arrow light 12 can point in the same direction as the first arrow light 11, or it can point vertically, so that the vehicle arrow warning system indicates that the following vehicle 100 can pass through the road on the side indicated by the first arrow light 11. This vehicle arrow warning system can adjust the direction of the first arrow light 11 and the second arrow light 12 according to the current road conditions, dynamically adjusting according to real-time road conditions to meet adaptability under complex working conditions and improve the safety of the working vehicle 100 and the following vehicles 100.

[0046] Optionally, the support mechanism 2 includes a first support group 21 and a second support group 22. The first support group 21 and the second support group 22 are spaced apart along the vehicle width direction Y at the rear of the vehicle 100. A first arrow light 11 is disposed on the first support group 21, and the first support group 21 controls the first arrow light 11 to switch between a first position a and a second position a. A second arrow light 12 is disposed on the second support group 22, and the second support group 22 controls the second arrow light 12 to switch between a first position b and a second position b. In this embodiment, the first arrow light 11 and the second arrow light 12 are supported and their positions switched by the first support group 21 and the second support group 22, respectively. In other embodiments, the first arrow light 11 and the second arrow light 12 may also be disposed on a single support group.

[0047] Optionally, the first bracket assembly 21 includes a first fixed frame 211 and a first swing frame 212. The first fixed frame 211 is fixed to the rear of the vehicle 100. The first swing frame 212 is pivotally connected to the first fixed frame 211 via a first pivot shaft 213, which is arranged along the vehicle length direction X. The first arrow light 11 is disposed on the first swing frame 212. The first swing frame 212 swings relative to the first fixed frame 211 to switch the first arrow light 11 between a first position a and a second position a. In this embodiment, the first fixed frame 211 includes a first base and a first upright. The first base is fixed to the rear of the vehicle 100. One end of the first upright is fixed to the first base, and the first upright is arranged along the vehicle height direction Z. The other end of the first upright is pivotally connected to the first swing frame 212 via the first pivot shaft 213, thereby allowing the first swing frame 212 to swing relative to the first upright to switch the first arrow light 11 between a first position a and a second position a.

[0048] Optionally, the second bracket assembly 22 includes a second fixed frame 221 and a second swing frame 222. The second fixed frame 221 is fixed to the rear of the vehicle 100. The second swing frame 222 is pivotally connected to the second fixed frame 221 via a second pivot shaft 223, which is arranged along the vehicle length direction X. The second arrow light 12 is disposed on the second swing frame 222. The second swing frame 222 swings relative to the second fixed frame 221 to switch the second arrow light 12 between a first position b and a second position b. In this embodiment, the second fixed frame 221 includes a second base and a second upright. The second base is fixed to the rear of the vehicle 100. One end of the second upright is fixed to the second base and is arranged along the vehicle height direction Z. The other end of the second upright is pivotally connected to the second swing frame 222 via the second pivot shaft 223, thereby allowing the second swing frame 222 to swing relative to the second upright to switch the second arrow light 12 between a first position b and a second position b.

[0049] Optionally, the first support assembly 21 further includes a first abutment block 214, which is fixed to the first fixed frame 211 on the side away from the second support assembly 22 along the vehicle width direction Y. At the first position a, the first swing frame 212 and the first abutment block 214 abut against each other. In this embodiment, when the first swing frame 212 and the first abutment block 214 abut against each other, the first abutment block 214 supports the first swing frame 212, causing the first swing frame 212 to abut against the first abutment block 214 under the action of gravity. At this time, the direction of the first arrow light 11 is exactly away from the second arrow light 12 along the vehicle width direction Y. At the second position a, the first arrow light 11 rotates to the side of the first fixed frame 211 away from the first abutment block 214. At this time, the first arrow light 11 points in the vehicle height direction Z, thus not misleading the vehicle 100 behind. In other embodiments, the first arrow light 11 may point to the second arrow light 12 along the vehicle width direction Y, so that the first arrow light 11 and the second arrow light 12 both point in the same direction.

[0050] The second support assembly 22 further includes a second abutment block 224, which is fixed to the second fixed frame 221 on the side away from the first support assembly 21 along the vehicle width direction Y. At the first position b, the second swing frame 222 and the second abutment block 224 abut against each other. In this embodiment, when the second swing frame 222 and the second abutment block 224 abut against each other, the second abutment block 224 supports the second swing frame 222, causing the second swing frame 222 to abut against the second abutment block 224 under the action of gravity. At this time, the direction of the second arrow light 12 is exactly away from the first arrow light 11 along the vehicle width direction Y. At the second position b, the second arrow light 12 rotates to the side of the second fixed frame 221 away from the second abutment block 224. At this time, the second arrow light 12 points in the vehicle height direction Z, thus not misleading the vehicle 100 behind. In other embodiments, the second arrow light 12 can point in the first arrow light 11 along the vehicle width direction Y, so that the first arrow light 11 and the second arrow light 12 both point in the same direction.

[0051] Optionally, the first support assembly 21 further includes a first elastic element 215. One end of the first elastic element 215 is fixedly connected to the first fixed frame 211 and spaced apart from the first pivot shaft 213, and the other end of the first elastic element 215 is fixedly connected to the first swing frame 212 and spaced apart from the first pivot shaft 213. In this embodiment, when the vehicle 100 travels on a bumpy road surface, the first elastic element 215 can keep the first swing frame 212 in its current first position a or second position a.

[0052] The second support assembly 22 further includes a second elastic element 225. One end of the second elastic element 225 is fixedly connected to the second fixed frame 221 and spaced apart from the second pivot shaft 223. The other end of the second elastic element 225 is fixedly connected to the second swing frame 222 and spaced apart from the second pivot shaft 223. In this embodiment, when the vehicle 100 travels on a bumpy road surface, the second elastic element 225 can keep the second swing frame 222 in its current first position b or second position b.

[0053] Optionally, both the first elastic element 215 and the second elastic element 225 are tension springs.

[0054] Different types of vehicles 100 have different widths and different installation positions at the rear of the vehicles 100. As a result, the distance between the first arrow light 11 and the second arrow light 12 along the width direction Y may be greater than or less than the width of the vehicle 100. This would result in the first arrow light 11 and the second arrow light 12 not having visual clearance along the width direction of the vehicle 100. To solve this problem, optionally, the first swing frame 212 includes a first swing rod 2121 and a first telescopic tube 2122. One end of the first swing rod 2121 is pivotally connected to the first fixed frame 211 through a first pivot shaft 213. The first telescopic tube 2122 is sleeved on the first swing rod 2121 and has two states: relatively fixed and relatively sliding with the first swing rod 2121. The first arrow light 11 is fixed to the first telescopic tube 2122. The second swing frame 222 includes a second swing rod 2221 and a second telescopic tube 2222. One end of the second swing rod 2221 is pivotally connected to the second fixed frame 221 via a second pivot shaft 223. The second telescopic tube 2222 is sleeved on the second swing rod 2221 and has two states: relatively fixed and relatively sliding. The second arrow light 12 is fixed to the second telescopic tube 2222. In this embodiment, the above-mentioned arrangement can adjust the distance between the first arrow light 11 and the second arrow light 12 along the vehicle width direction Y, so that the distance between the first arrow light 11 and the second arrow light 12 along the vehicle width direction Y is equal to the width of the vehicle 100. At night, it has visibility capability, further ensuring the safety of the vehicle 100 and the vehicles 100 behind it.

In this embodiment, the first swing frame 212 further includes a first nut, a first limiting pin 2125 which is a first bolt, the first nut is fixed to the first telescopic tube 2122 and coaxially arranged with the first through hole 2124, the first limiting pin 2125 is screwed to the first nut, the first limiting pin 2125 passes through the first through hole 2124 and selectively inserts into one of the plurality of first limiting holes 2123 to achieve relative fixation of the first telescopic tube 2122 and the first swing rod 2121. When the first limiting pin 2125 is screwed on, and thus the first limiting pin 2125 is disengaged from the first limiting hole 2123, the first telescopic tube 2122 and the first swing rod 2121 can slide relative to each other to achieve the extension and retraction of the first swing frame 212.

[0056] Optionally, the second swing rod 2221 is provided with a plurality of second limiting holes 2223 at intervals along the length direction, the second telescopic tube 2222 is provided with a second through hole 2224, and the second swing frame 222 also includes a second limiting pin 2225, which passes through the second through hole 2224 and selectively engages with one of the plurality of second limiting holes 2223. In this embodiment, the second swing frame 222 further includes a second nut, and the second limiting pin 2225 is a second bolt. The second nut is fixed to the second telescopic tube 2222 and is coaxially arranged with the second through hole 2224. The second limiting pin 2225 is screwed to the second nut. The second limiting pin 2225 passes through the second through hole 2224 and is selectively inserted into one of the multiple second limiting holes 2223 to achieve relative fixation of the second telescopic tube 2222 and the second swing rod 2221. When the second limiting pin 2225 is screwed on, and thus the second limiting pin 2225 is disengaged from the second limiting hole 2223, the second telescopic tube 2222 and the second swing rod 2221 can slide relative to each other to achieve the extension and retraction of the second swing frame 222.

[0057] Optionally, the first swing frame 212 further includes a first support body 2126 and a first limiting body 2127. The first support body 2126 is disposed on the outer peripheral wall of the first swing rod 2121 and located on the side away from the first fixed frame 211.

In this embodiment, the first support body 2126 and the first limiting body 2127 are arranged opposite to each other along the length direction of the first swing rod 2121. When the first support body 2126 and the first limiting body 2127 abut against each other along the length direction of the first swing rod 2121, the first swing rod 2121 can be prevented from dislodging from the first telescopic tube 2122. In addition, the first support body 2126 and the first limiting body 2127 can fill the gap between the first swing rod 2121 and the first telescopic tube 2122, so as to avoid large shaking between the first swing rod 2121 and the first telescopic tube 2122.
