Description

Technical Field

[0001] The invention relates to the field of traffic production, and in particular to a curve warning indicating device for safe driving of vehicles. Background Art

[0002] In scenes such as mountain roads and curves on urban roads, when the vehicle reaches a curve, the driver's line of sight is often blocked by obstacles such as mountains, buildings, and trees. It is difficult for the driver to observe the oncoming vehicles on the other side of the curve in advance, which makes it impossible for the driver to make accurate judgments on the traffic conditions ahead of the curve in advance, increasing the possibility of a collision accident. Therefore, a curve warning indicator device for safe vehicle driving is needed. Through early warning, the driver can adjust the driving behavior in time to avoid collisions with oncoming vehicles and obstacles around the curve due to unclear curve conditions or excessive speed, thereby reducing the incidence of head-on collisions and scratch accidents.

[0003] During the use of the existing curve warning indicator device for safe driving of vehicles, the warning indicator device may collide on the curve due to driver's operating errors, vehicle loss of control, and poor road conditions (such as slippery road surface, icy, etc.). The traditional warning device is generally fixed next to the curve, with a relatively fixed position and lacks sufficient protection and avoidance design. When the vehicle deviates from the driving, the impact force directly acts on the device itself, which can easily cause the shell to crack and the supporting structure to deform or break. Frequent device damage requires a lot of manpower, material and financial resources for repair or replacement, which not only increases the maintenance cost of road facilities, but also the vehicle directly collides with the warning device head-on. Due to the lack of buffering and direction guidance, the huge impact force generated at the moment of collision causes serious deformation of the vehicle, and the people in the car are injured or even their lives are endangered.

[0004] Therefore, it is necessary to propose a curve warning indicator device for safe driving of vehicles to solve the above technical problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a curve warning indicator device for safe vehicle driving, which solves the technical problems that the prior curve warning indicator devices are fixed in place and lack protective avoidance design, which may easily cause damage to the vehicle itself when the vehicle collides due to operating errors, loss of control or poor road conditions, increase maintenance costs, and cause serious deformation of the vehicle, endangering the lives of people in the vehicle.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figure 1-Figure 3As shown, a curve warning indicator device for safe driving of vehicles comprises: a warning sign 1, a warning display screen 11, which is arranged on the warning sign 1 and is used to issue warning information related to the curve; a reinforcement seat 12, which is arranged below the warning sign 1 and is used to enhance the overall stability of the curve warning indicator device; a shock-absorbing telescopic rod 13, at least one of which is arranged at the left and right ends of the warning sign 1; a shock-absorbing frame 14, which is a hollow frame structure and is connected to the shock-absorbing telescopic rod 13, and the shock-absorbing frame 14 and the shock-absorbing telescopic rod 13 work together to alleviate the impact force of the outside on the warning sign 1; an anti-collision component 2, which is arranged on the reinforcement seat 12 and is used to prevent the vehicle body from hitting the warning sign 1 generates a frontal impact force, the anti-collision component 2 includes a first avoidance rod 21, which is installed below the warning sign 1; a concave seat 22, which is arranged above the reinforcement seat 12, and the first avoidance rod 21 is rotatably connected inside the concave seat 22 through a rotating shaft, and the horizontal section of the concave seat 22 is used to keep the first avoidance rod 21 in a vertical state; a limit seat 23, which is arranged at the left and right ends of the reinforcement seat 12; a limit rod 24, which is provided with two, one end of which is installed at the left and right ends of the warning sign 1 through a bolt 216, and is slidably connected with the limit seat 23; a first compression spring 25, which is rotatably connected to the side of the limit seat 23 away from the warning sign 1, and the first compression spring 25 is arranged at the other end of the limit rod 24.

[0038] It should be noted that when a car loses control while driving on a curve and collides with the warning indicator, the entire device will work together according to the following process:

[0039] Initial buffering: The car body first contacts the shock-absorbing frame 14. Since the shock-absorbing frame 14 is a hollow frame structure, this structure itself has a certain elasticity and deformation space, which can initially disperse part of the impact force. At the same time, the shock-absorbing frame 14 is connected to the shock-absorbing telescopic rod 13, and it will transfer the impact force to the shock-absorbing telescopic rod 13. The two work together to buffer the impact force for the first time, avoiding the impact force directly acting on the warning sign 1 and other key components, and preventing the warning sign 1 from being damaged by the instantaneous strong impact force;

[0040] Linked displacement: while the shock-absorbing frame 14 and the shock-absorbing telescopic rod 13 are buffering, the shock-absorbing telescopic rod 13 will drive the warning sign 1 to move backward and squeeze after being subjected to the impact force. At this time, the first avoidance rod 21 rotates on the concave seat 22 with the rotation axis as the center due to the displacement of the warning sign 1. When the first avoidance rod 21 rotates, the limit rod 24 will slide in the limit seats 23 at the left and right ends of the reinforcement seat 12. The limit seats 23 guide and limit the limit rod 24 to ensure the stability and controllability of the warning sign 1 during the rotation process. The present invention forms a multi-level protection system through the initial buffering of the shock-absorbing frame 14 and the shock-absorbing telescopic rod 13, as well as a series of subsequent actions such as the rotation of the warning sign 1, the cooperation of the limit rod 24 and the limit seat 23, and the stretching of the first compression spring 25, which greatly improves the protection capability of the warning sign 1 and ensures that it can remain relatively intact when subjected to a strong collision and continue to play a warning function;

[0041] When the warning sign 1 rotates to a horizontal state, the lower part of the vehicle body keeps in contact with the shock absorbing frame 14. At this time, the shock absorbing frame 14 continues to bear part of the impact force from the vehicle body, and the warning sign 1, due to the push of the impact force of the vehicle body, will move along the direction of the limit rod 24 away from the impact direction of the vehicle body. In this process, the first compression spring 25 will be stretched. During the stretching process, the first compression spring 25 converts the impact force into its own elastic potential energy, further absorbing and buffering the remaining impact force. The rotation design of the warning sign 1 not only changes the direction of the impact force of the vehicle body, but also reduces the destructive force of the frontal collision.

[0042] At the same time, the stretching of the first compression spring 25 also provides a certain resistance to the movement of the warning sign 1, slowing down its movement speed, and preventing the warning sign 1 from being separated from the device or being more seriously damaged due to excessive displacement;

[0043] Through the above series of actions, the entire device effectively disperses and absorbs the impact force generated by the car collision, protects the warning sign 1 and other key components, and after the impact force disappears, the first compression spring 25 will retract by its own elasticity, driving the warning sign 1 to reset along the direction of the limit rod 24, so that the warning indicator device can quickly return to a normal working state and be ready to deal with the next possible collision at any time;

[0044] like Figure 3-Figure 4 As shown, one end of the two limit rods 24 slides through the limit seat 23 and is installed with a tire frame seat 26, and the end of the tire frame seat 26 away from the warning sign 1 is rotatably connected to a pulley 261.

[0045] It should be noted that, with the rotation and sliding of the limit rod 24, the position of the tire frame seat 26 will also change accordingly. When the chassis of the vehicle body contacts the tire frame seat 26, the tire frame seat 26, driven by the limit rod 24, begins to exert an upward force on the chassis of the vehicle body, changing the focus point and direction of the collision of the vehicle body, further avoiding the direct impact of the vehicle body on the warning sign 1, and strengthening the protection of the core components of the warning indicator device. The top of the tire frame seat 26 is a horizontal end, and this horizontal end has a large contact area with the chassis of the vehicle body, which can provide a stable supporting force, so that the entire device is more stable in the process of bearing the impact of the vehicle body, and is not easy to tip over or be damaged due to uneven force.

[0046] As the limit rod 24 continues to rotate, the tire frame seat 26 gradually lifts the vehicle body. During this process, the outer side of the pulley 261 extends out of the horizontal end of the tire frame seat 26. When the vehicle body and the tire frame seat 26 move or rub relative to each other, the pulley 261 will roll to reduce the friction between the vehicle body and the tire frame seat 26, avoiding damage to the tire frame seat 26 due to excessive friction, and also making the movement of the vehicle body on the tire frame seat 26 smoother.

[0047] The surface of the pulley 261 is provided with anti-skid patterns, which are distributed in a ring shape on the outer circumference of the pulley 261. When the vehicle body and the tire frame seat 26 move relative to each other, the anti-skid patterns can increase the friction between the pulley 261 and the vehicle body, making the movement of the vehicle body on the tire frame seat 26 more stable, further improving the reliability of the device in response to vehicle collisions. The outer side of the pulley 261 extends out of the horizontal end of the tire frame seat 26 to avoid wear on the tire frame seat 26 due to excessive friction, thereby extending the service life of the tire frame seat 26.

[0048] like Figure 3-Figure 4 As shown, a curved groove 260 is provided below the tire frame seat 26 and on a side away from the warning sign 1 , and a shock-absorbing convex pad is installed in the curved surface of the curved groove 260 .

[0049] It should be noted that when the vehicle body continues to move on the surface of the tire frame seat 26, the wheel fits inside the curved groove 260. The curved surface design of the curved groove 260 fits the wheel contour more closely. During a vehicle collision, if the wheel contacts the curved groove 260, the contact stability between the wheel and the tire frame seat 26 can be enhanced to prevent the wheel from slipping, so that the tire frame seat 26 can lift the vehicle body chassis more effectively, thereby enhancing the reliability of the device in responding to collisions.

[0050] like Figure 2 and Figure 5As shown, a cavity groove is opened inside the reinforcement seat 12, and a lifting slider 211 is installed at the bottom of the concave seat 22, which slides through the reinforcement seat 12 and is installed. The lifting slider 211 is connected inside the reinforcement seat 12 by a slide rail, and the bottom wall of the cavity groove is rotatably connected to a screw rod 212, and the top of the reinforcement seat 12 is rotatably connected to a wrench torque disk 213 fixedly connected to the screw rod 212, and spring rods 214 tightly attached to the cavity groove are symmetrically installed below the lifting slider 211, and a fixed seat 215 is installed on the top of the limit seat 23, and a bolt 216 is rotatably connected in the fixed seat 215, and a plurality of bolt holes 217 in a vertical form are opened at the left and right ends of the reinforcement seat 12, and the bolt 216 is threadedly connected in one of the bolt holes 217.

[0051] When it is necessary to adjust the warning indicator device according to the different depths of the bottom surface of the curve or for different types of cars, the operator rotates the wrench torsion plate 213. The rotation of the wrench torsion plate 213 will drive the screw rod 212 to rotate on the bottom wall of the cavity groove inside the reinforcement seat 12. When the screw rod 212 rotates, the lifting slider 211 will perform lifting and lowering movements along the slide rail inside the reinforcement seat 12. Since the lower side of the concave seat 22 slides through the interior of the reinforcement seat 12 and is installed together with the lifting slider 211, the lifting and lowering of the lifting slider 211 will drive the concave seat 22 to rise and fall synchronously, thereby changing the height of the connection point between the reinforcement seat 12 and the warning indicator 1. Through the adjustable connection point height, it can be adjusted according to the different depths of the bottom surface of the curve, ensuring that the warning indicator device can maintain the best working state under various complex curve terrain conditions, thereby improving the environmental adaptability of the device.

[0052] The two limit seats 23 are connected by slide rails at the left and right ends of the reinforcement seat 12. During the adjustment process, the limit seat 23 can be moved to a suitable position along the slide rail by loosening the bolts 216 according to actual needs, and then the bolts 216 can be tightened to fix the limit seat 23 in the new position, thereby cooperating with the height adjustment of the concave seat 22 to ensure the structural stability of the entire device.

[0053] like Figure 5 As shown, the left and right ends of the concave seat 22 are provided with limit display holes 220, and the limit display holes 220 are arranged horizontally.

[0054] During the height adjustment process of the warning sign 1, as the concave seat 22 rises and falls, the position of the limit display hole 220 will also change accordingly. When the warning sign 1 is adjusted to a suitable height, the limit display hole 220 will expose half of its body on the reinforcement seat 12. At this time, the bolt 216 that is rotatably connected in the fixed seat 215 on the limit seat 23 is aligned with one of the multiple bolt holes 217 vertically arranged on the left and right ends of the reinforcement seat 12. The installer can intuitively observe the alignment of the bolt 216 and the bolt hole 217 through the limit display hole 220, thereby quickly screwing the bolt 216 into the corresponding bolt hole 217 to achieve a quick connection between the limit seat 23 and the reinforcement seat 12.

[0055] like Figure 6 As shown, a plurality of ratchet grooves 240 are provided on the outer side of the limit rod 24, and a linkage groove 221 is also provided inside the limit seat 23. A ratchet plate 222 inserted into the inner side of one of the ratchet grooves 240 is rotatably connected in the linkage groove 221, and a second compression spring 223 is connected to the top of the ratchet plate 222 and the side wall of the linkage groove 221. The end of the limit seat 23 away from the reinforcement seat 12 is rotatably connected to a drive plate 224 fixedly connected to the ratchet plate 222.

[0056] It should be noted that when the car body collides with the warning sign 1 and causes it to rotate to the horizontal end, the tire frame seat 26 lifts the car body to cope with the impact of the car body. When the limit rod 24 moves, the ratchet plate 222 is inserted into the inner side of the corresponding ratchet groove 240 on the limit rod 24 under the elastic force of the second compression spring 223. In this way, the ratchet plate 222 cooperates with the ratchet groove 240 to limit the movement of the limit rod 24, thereby improving the stability of the tire frame seat 26 in the process of lifting the car body, ensuring that the tire frame seat 26 can continue to effectively withstand the impact of the car body. When the impact force disappears and the warning indicator device needs to be restored to the initial state, an external force is applied to the ratchet plate 222 through the driving plate 224, and the driving plate 224 drives the ratchet plate 222 to overcome the elastic force of the second compression spring 223, so that it leaves the ratchet groove 240 on the limit rod 24, so that the ratchet plate 222 also returns to the initial position, ready for the next possible impact.

[0057] The working principle of the present invention is that the curve warning indicator device for safe driving of vehicles is used. When a car collides, the car body first contacts with the shock-absorbing frame 14 with a hollow frame structure, and its elasticity and deformation space initially disperse the impact force, and then work together with the shock-absorbing telescopic rod 13 to buffer the impact force for the first time to protect the warning sign 1. The shock-absorbing telescopic rod 13 drives the warning sign 1 to move and squeeze backward, and the first avoidance rod 21 rotates on the concave seat 22, driving the limit rod 24 to slide in the limit seat 23. The limit seat 23 ensures that the rotation of the warning sign 1 is stable and controllable. The warning sign 1 rotates to a horizontal level, and the bottom of the car body contacts the shock-absorbing frame 14 again. The warning sign 1 moves along the direction of the limit rod 24, stretching the first compression spring 25 to further absorb and buffer the impact force, slow down the moving speed of the warning sign 1, and avoid excessive positioning. After the tire frame 26 is damaged and the impact force disappears, the first compression spring 25 retracts, driving the warning sign 1 to reset, and the device is ready to deal with the next collision. The limit rod 24 drives the tire frame seat 26, and its top horizontal end contacts the vehicle chassis to provide stable support and lift the vehicle body, changing the collision force point and direction, and further protecting the warning sign 1. The pulley 261 at one end of the tire frame seat 26 reduces the friction with the vehicle body and prevents the tire frame seat 26 from being damaged. The shock-absorbing convex pad in the curved groove 260 under the tire frame seat 26 enhances the contact stability with the wheel, prevents slipping, and improves the reliability of dealing with collisions. According to the depth of the bottom surface of the curve or the vehicle model, the wrench torsion disk 213 is turned to drive the screw rod 212 to rotate, so that the lifting slider 211 is lifted and lowered along the slide rail, thereby driving the concave seat 22 to lift and lower, changing the height of the connection point between the reinforcement seat 12 and the warning sign 1, and improving the environmental adaptability of the device.
