Description

Technical Field

[0001] The utility model belongs to the field of road construction equipment, and in particular relates to an avoidance warning device for engineering vehicles. Background Art

[0002] With the progress of urbanization, the maintenance demand of urban areas and highways in my country is increasing day by day. Engineering vehicles are required to inspect and repair designated sections of roads without closing roads. During the inspection and repair process, the engineering vehicles are stationary or driving at low speed, which poses a great safety hazard to the high-speed approaching vehicles behind. If the rear driver fails to find the engineering vehicles in front in time, it will cause safety accidents such as rear-end collisions. Therefore, a significant warning device should be added behind the engineering vehicles so that the rear vehicles can know the construction situation in front in advance and make timely avoidance;

[0003] The traditional method is to tow a warning car 100 meters behind the engineering vehicle. However, in the curved area, the driving track of the warning car cannot completely overlap with the engineering vehicle. In serious cases, it will drive into the adjacent lane, causing the driver behind to make an error in judgment and fail to change lanes in time, which also poses a safety hazard.

[0004] Some sites also use the method of installing light warning devices on the rear end of engineering vehicles. However, due to the size of the engineering vehicles, the height of the rear end of some engineering vehicles is relatively low, which shortens the detection distance of the warning device and fails to achieve the desired warning effect. Increasing the installation height will cause installation instability. For example, when the engineering vehicle is driving at high speed, the warning device will shake and the installation rod will break, which will also lose its desired warning effect. Utility Model Content

[0005] The purpose of the invention of the utility model is to overcome the defects described in the background technology, thereby realizing an avoidance warning device for engineering vehicles, adopting a light frame structural design, providing a variety of magnified indication methods, effectively improving the visual distance of the rear driver, and facilitating the driver to quickly understand the construction situation ahead and quickly make judgments on lane change operations. At the same time, a folding support rod design is adopted, and when the engineering vehicle is driving fast, the light frame can be laid down to improve driving stability.

[0006] In order to achieve the above-mentioned invention object, the technical solution of the utility model is:

[0007] An engineering vehicle avoidance warning device, comprising:

[0008] The light frame is a rectangular structure connected diagonally, with individually controlled display lights evenly distributed on the surface, used to form an indicator arrow pointing to a single or multiple corners;

[0009] The support rod is a double-section foldable support rod, the top of which is hinged to the upper frame of the lamp frame, and a telescopic cylinder for adjusting the folding angle of the support rod is arranged in the middle;

[0010] The ground hinge is used to hinge the bottom end of the support rod and the bottom end of the lamp frame to the load-bearing vehicle.

[0011] Specifically, it also includes a T-shaped hinge, the three ends of which are respectively hinged to the long rod, the short rod and the movable end of the telescopic cylinder of the support rod; through the design of the T-shaped hinge, when the support rod is fully folded, the long rod and the short rod can be in a parallel state, thereby reducing the stress on the hinge in the folded state and improving the service life of the hinge;

[0012] The height direction of the hinge point of the free end of the telescopic cylinder is between the hinge points of the short rod, the long rod and the T-hinge. By designing the hinge point of the telescopic cylinder, when the support rod is in a fully folded state, there is a certain angle between the extension line of the telescopic cylinder and the short rod, avoiding the problem of too small torque caused by overlapping of the axes of the two. This can effectively reduce the initial working power of the telescopic cylinder and reduce the overall space occupied by the equipment, making it easier to install it on the engineering vehicle later.

[0013] Specifically, the length of the short rod is L1, the length of the long rod is L2, the height of the lamp frame is L, and the hinge distance between the support rod and the bottom of the lamp frame is X;

[0014] (L1+L2) 2 =L 2 +X 2

[0015] L2-L1=LX.

[0016] By designing the length of the long rod and the short rod inside the support rod, the design requirement of the lamp frame being folded flat is met, so that when the engineering vehicle is driving at high speed, the lamp frame can be completely flat, reducing its air resistance. At the same time, it can increase its stability during movement, reduce the loss of the ground hinge, and extend the overall service life.

[0017] Specifically, support rods are provided on both sides of the lamp frame, and a transverse reinforcing rod is provided between the T-shaped hinges of the two groups of support rods;

[0018] By adding lateral reinforcement rods, the consistency of the T-shaped hinges on both sides is improved, and the lateral shaking of the lamp frame and the support rod can be effectively suppressed.

[0019] Specifically, a distance sensor for detecting the distance to the rear vehicle is provided at the front end of the lamp frame. Distance sensors such as laser radar, visual cameras and other detection elements that can detect the distance to the rear vehicle and the approach speed are added. By analyzing the driving trajectory and speed of the rear vehicle, it is determined whether the driver has discovered the engineering vehicle and whether he has made evasive action. If the driver does not make corresponding evasive action, the flashing frequency of the warning light at the front end of the lamp frame is controlled to change, or the display graphic is changed, so as to attract the attention of the rear driver as much as possible and make evasive action in time, thereby achieving the effect of active warning.

[0020] Specifically, a receiving groove for receiving the support rod is provided on the back of the lamp frame.

[0021] Compared with the prior art, the engineering vehicle avoidance warning device of the utility model has at least the following beneficial effects:

[0022] 1. The engineering vehicle avoidance warning device of the utility model adopts a light frame structure design. Compared with the traditional light box design, it has a smaller windward area and has better stability when the engineering vehicle is transferred at high speed or the wind speed is high at the construction site.

[0023] 2. At the same time, the support of the lamp frame adopts a foldable support rod structure design. When there is no need to warn, the lamp frame can be folded to be level with the engineering vehicle compartment, thereby lowering the overall center of gravity and facilitating the improvement of the driving stability of the engineering vehicle.

[0024] 3. Adding distance sensors and controllable light frame display content can clearly display the instructions, actively detect the trajectory and avoidance trend of the rear vehicle, and actively remind the rear driver to perform avoidance operations by changing the display content or flashing frequency, thereby playing an active warning role.

[0034] Embodiment 1

[0035] This embodiment discloses an engineering vehicle avoidance warning device, comprising: a light frame 1, which is a rectangular structure and is diagonally connected, and has individually controlled display lights evenly distributed on the surface, which are used to form an indication arrow pointing to a single or multiple corners;

[0036] See also Figure 5-Figure 7 , through the special structural design of the lamp frame 1, its windward area is reduced, its own rigidity is improved, and deformation during use is avoided; in actual use, such as side road construction, it can be displayed as follows Figure 5 or Figure 7 The pattern guides the rear vehicles to change lanes to the designated lane to avoid collisions between the rear vehicles and the construction vehicles. If the construction vehicles are working in the middle lane or driving at a low speed, the Figure 6 The pattern guides the vehicle to change lanes to any lane on either side to avoid collision;

[0037] The support rod 2 is a double-section foldable support rod, the top of which is hinged to the upper frame of the lamp frame 1, and a telescopic cylinder 3 for adjusting the folding angle of the support rod 2 is arranged in the middle;

[0038] See also Figure 1-Figure 4 The telescopic cylinder 3 is preferably an oil cylinder that can be connected to the vehicle hydraulic system to drive the support rod 2 to move. At the same time, a T-hinge 203 is set at the folding position of the support rod 2. The three ends of the T-hinge 203 are respectively hinged to the long rod 202, the short rod 201 of the support rod 2 and the movable end of the telescopic cylinder 3; through the design of the T-hinge 203, the support rod 2 can be in a state of parallel with the long rod 202 and the short rod 201 when it is fully folded. When the support rod 2 is fully folded, the height direction of the hinge point of the telescopic cylinder 3 is between the hinge points of the short rod 201 and the long rod 202. Through the design of the hinge point position of the telescopic cylinder 3, when the support rod 2 is fully folded, there is a certain angle between the extension line direction of the telescopic cylinder 3 and the short rod 201, so as to avoid the problem of too small torque caused by the overlap of the axes of the two, which can effectively reduce the initial working power of the telescopic cylinder 3 and reduce the overall space occupied by the equipment, which is convenient for the later installation of the engineering vehicle.

[0039] The length of the short rod 201 is L1, the length of the long rod 202 is L2, the height of the lamp frame 1 is L, and the hinge distance between the support rod 2 and the bottom of the lamp frame 1 is X;

[0040] (L1+L2) 2 =L 2 +X 2

[0041] L2-L1=LX.

[0042] A receiving groove for accommodating the support rod 2 is provided on the back of the lamp frame 1. By designing the length of the long rod 202 and the short rod 201 inside the support rod 2, the design requirement of the lamp frame 1 being folded and laid flat is met, so that when the engineering vehicle is traveling at high speed, the lamp frame 1 can be completely laid flat to reduce its air resistance. At the same time, it can increase its stability during movement, reduce the loss of the ground hinge 5, and extend the overall service life.

[0043] The ground hinge 5 is used to hinge the bottom end of the support rod 2 and the bottom end of the lamp frame 1 to the load-bearing vehicle.

[0044] For engineering vehicles that use plate-type transportation, the height of the rear end of the vehicle plate is relatively low. If the warning mechanism is directly installed at the rear, the installation height is limited and the rear visible distance is relatively short. The rear driver can only find the engineering vehicle in front when the distance is relatively close. After fixing this product on the rear end of the vehicle plate through the ground hinge 5, the display height and display area of ​​the warning device can be effectively improved, and the rear visible distance can be effectively extended, so that the rear driver can find the engineering vehicle at a longer distance and avoid it as soon as possible. Moreover, after installation, the original loading area of ​​the vehicle is less occupied, and the original cargo capacity is not affected.

[0045] Embodiment 2:

[0046] The difference from the first embodiment is that:

[0047] See also Figure 2 , support rods 2 are provided on both sides of the left and right sides of the lamp frame 1, and a transverse reinforcing rod 6 is provided between the T-shaped hinges 203 of the two groups of support rods 2;

[0048] By adding the transverse reinforcing rod 6 , the consistency of the T-shaped hinges 203 on both sides is improved, and the transverse shaking of the lamp frame 1 and the support rod 2 can be effectively suppressed.

[0049] Embodiment three:

[0050] The difference from the first embodiment is that:

[0051] A distance sensor 4 for detecting the distance to the rear vehicle is provided at the front end of the lamp frame 1. The distance sensor 4 is increased, such as a laser radar, a visual camera or other detection elements that can detect the distance to the rear vehicle and the approach speed. By analyzing the driving trajectory and speed of the rear vehicle, it is determined whether the driver has discovered the engineering vehicle and whether he has made evasive action. If the driver does not make corresponding evasive action, the flashing frequency of the warning light at the front end of the lamp frame 1 is controlled to change, or the display pattern is changed, so as to attract the attention of the rear driver as much as possible and make evasive action in time, thereby achieving the effect of active warning.

[0052] The working principle of the engineering vehicle avoidance warning device of the utility model:

[0053] The warning device is installed at the rear end of the engineering vehicle through the ground hinge 5. When a warning is needed, the support rod 2 is opened by the support function of the telescopic cylinder 3 to form a triangular stable structure with the lamp frame 1. By changing the lighting sequence of the indicator lights in the lamp frame 1, the display of arrows in different directions is realized, so that the rear driver can find the engineering vehicle at a longer distance and change lanes in time to avoid it;

[0054] When there is no need to issue a warning, the warning device can be folded down by folding the support rod 2, thereby reducing its windward area and the center of gravity of the entire equipment, thereby improving the driving stability of the engineering vehicle.

[0055] It should be noted that, when the device is implemented, the structure described in the drawings of this specification is not a fixed and unchanging implementation method. For example, the angle adjustment method and fixing method of the support rod 2 can be changed according to actual needs, including but not limited to chain drive, gear drive, belt drive and telescopic cylinder drive. In addition, the drawings of this specification and the drawings of the abstract are only schematic diagrams and do not represent the specific structure and actual quantity of the specific implementation.
