Description

Technical Field

[0001] This utility model relates to the field of vehicle safety emergency warning equipment, and in particular to a fully automatic folding triangular warning sign. Background Technology

[0002] With the rapid development of transportation, the number of motor vehicles is increasing year by year, leading to a corresponding rise in traffic accidents. Placing a warning triangle behind the vehicle after an unexpected breakdown is essential for ensuring driving safety. However, existing warning triangles are space-consuming, difficult to store, and inconvenient to carry or move. Furthermore, placing the warning triangle mainly relies on the driver or passengers getting out of the vehicle to do so manually. On the one hand, due to inclement weather, obstructed visibility, and poor lighting in tunnels, there is a risk of the operator being struck by vehicles from behind or to the side during placement and retrieval. On the other hand, the warning triangle needs to be placed 150 meters behind the vehicle, and manual placement presents certain accuracy problems, with inconsistent placement distances and significant errors. Therefore, a new type of warning triangle needs to be designed to reduce placement risks and improve placement accuracy. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fully automatic placement and folding triangular warning sign, which reduces placement risks while improving placement accuracy.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use.

Therefore, they should not be construed as limitations on this utility model. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] Example:

[0033] This embodiment provides a fully automatic placement and folding warning triangle, including a trolley and a warning triangle mounted on the trolley. When the vehicle is not malfunctioning, the warning triangle... Figure 4 As shown, the vehicle is in a folded state and stored in a storage compartment installed under the car chassis; in the event of a car malfunction, the vehicle slides out via the storage compartment's release system and automatically moves to 150 meters behind the car, with a warning triangle appearing as shown. Figure 3 As shown, it is in the unfolded state.

[0034] like Figure 2As shown, the storage compartment includes a plate and a release system. The plate includes a first support plate 5 and a second support plate 6, with the second support plate 6 embedded within the first support plate 5. The release system includes a DC motor 2, a motor lead-out shaft 3, and a traction rope 4. The DC motor 2 is fixed to the underside of the vehicle chassis via fixing bolt holes 1, and the motor lead-out shaft 3 extends from both sides of the DC motor 2. One end of the first support plate 5 is fixed to the underside of the vehicle chassis via a rotating shaft, and the other end is connected to one end of the traction rope 4 via a fixing bolt. The other end of the traction rope 4 is wound around the end of the motor lead-out shaft 3.

[0035] like Figure 1 As shown, a latch 19 is provided on the first support plate 5. The latch 19 stands upright when the trolley is in the storage compartment. A spring runs through the inside of the latch 19, and the latch 19 is connected to the first support plate 5 through the spring. Therefore, the latch 19 has a certain preload force, which can ensure that the trolley returns to its original position after moving when it is laid flat. When it is necessary to release the trolley, the DC motor 2 drives the motor lead-out shaft 3 to rotate, thereby releasing the traction rope 4 wrapped around the motor lead-out shaft 3. The end of the first support plate 5 that is not fixed to the car chassis flips downward, and the second support plate 6 extends obliquely downward from the first support plate 5 by gravity to extend the track of the trolley and play a guiding role. The trolley pushes open the latch 19 by gravity and the power provided by the travel motor, thus completing the release.

[0036] The vehicle includes a body and integrated sensor, steering, propulsion, and power supply systems. The control circuits and chips for each system are housed in cavities within the vehicle's interior. Specifically, the sensor system is used to collect environmental data, such as… Figure 5 As shown, it includes a visual camera 16, an infrared camera 7, and a radar 8. The steering system is used to generate and execute steering commands based on environmental data, such as... Figure 6 As shown, the steering system includes a rudder servo (an RDS3218 bidirectional axial servo is used in this embodiment) and a bogie 10. The rudder servo is mounted at the four corners of the vehicle body, and the bogie 10 is connected to the rudder servo, driving the bogie 10 through the rudder servo. The travel system is used to generate and execute travel commands based on environmental data. The travel system includes a travel motor and wheels 12. The travel motor is mounted on the bogie 10, and the wheels 12 are mounted on the axle 11 of the travel motor, driving the wheels 12 through the travel motor (a 36HM2004A4-XK micro disc motor is used in this embodiment). The power supply system is used to supply power to other systems. The power supply system includes a battery, a power supply circuit, and a charge / discharge control chip (a TP4056 is used in this embodiment), all installed in cavities inside the vehicle body.

[0037] The triangular warning sign includes a first side 13, a second side 14, and a third side 15. The triangular warning sign is folded and unfolded using a lifting system. For example... Figure 7As shown, the first sign edge 13 is rigidly connected to the trolley, and the second sign edge 14 is connected to the first sign edge 13 via a connecting shaft 17. The third sign edge 15 is connected to the second sign edge 14 via an arc-shaped groove on the third sign edge 15 and is limited by a convex shaft on the second sign edge 14. The third sign edge 15 is connected to the first sign edge 13 via the connecting shaft 17. The connecting shaft 17 extends through shaft components such as bushings and bearings, causing the second sign edge 14 to rotate, and the third sign edge 15 to unfold accordingly, forming an equilateral triangle with the three sign edges. LED light strips 18 are fixed on the first sign edge 13, the second sign edge 14, and the third sign edge 15 respectively. The flashing of the LED light strips 18 can enhance the visual effect and further ensure driving safety.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
