Description

Technical Field

[0001] This invention relates to the field of warning sign technology, and in particular to vehicle warning triangles. Background Technology

[0002] A car warning triangle is a device placed at least 50 meters behind a vehicle when it breaks down, stalls, or malfunctions, to warn following vehicles and improve road safety. Currently, most car warning triangles require manual deployment, which can delay deployment and increase the risk of rear-end collisions. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a car warning triangle to solve the problem that most current car warning triangles need to be manually unfolded during use, which leads to the inability to unfold the car warning triangle in a timely and quick manner, thus delaying the placement time and increasing the risk of rear-end collisions.

[0004] A car warning triangle includes a horizontal frame, a left tilting frame, and a right tilting frame. The upper end of the horizontal frame has a groove 1. The left tilting frame is located inside the groove 1 and is rotatably connected to the left side of the groove 1. One side of the left tilting frame has a groove 2. The right tilting frame is located inside the groove 2 and is rotatably connected to the groove 2. Reflectors are embedded and fixed at both ends of the horizontal frame, the left tilting frame, and the right tilting frame. Fluorescent cloth is fixed between the inner sides of the left tilting frame and the right tilting frame.

[0005] The groove has a guide groove at the bottom, and a guide block is slidably connected inside the guide groove. The upper part of the guide block extends out of the guide groove and is fixed with a guide sleeve. The upper part of the guide sleeve is rotatably connected to the other end of the right tilting frame. A spring is connected between the left part of the guide sleeve and the left end of the inner wall of the groove. The lower end of the guide block has a bottom groove, and a ball sleeve is slidably connected inside the bottom groove. A spring is connected between the upper part of the ball sleeve and the bottom of the bottom groove. A ball is slidably connected inside the ball sleeve. A locking hole is opened on the left side of the bottom of the guide groove, and the ball is inserted into the locking hole. Deformation support pads are fixed on both the left and right sides of the lower end of the cross frame.

[0006] Specifically, a rotating shaft is fixed to the upper left side inside the first groove, and the rotating shaft is movably connected to the left tilting frame. A rotating shaft is fixed to the right side inside the second groove, and one end of the right tilting frame is movably connected to the rotating shaft.

[0007] Specifically, the upper part of the guide sleeve and both the front and rear sides of the right tilting frame are fixed with protrusions, and a rotating shaft three is fixed between the protrusions. The rotating shaft three is movably connected to the other end of the right tilting frame.

[0008] Specifically, a guide post is fixed in the lower part of the groove, the guide post is located inside the spring, and the guide sleeve is movably sleeved on the outside of the guide post.

[0009] Specifically, the lower end of the ball sleeve has a rolling groove, the ball is located inside the rolling groove and is tactilely connected to the rolling groove, and the opening diameter of the lower end of the rolling groove is larger than the diameter of the ball.

[0010] Specifically, the deformable support pad has an inner cavity, and the inner cavity has a corrugated strip, with both the upper and lower ends of the corrugated strip fixed to the inner wall of the inner cavity.

[0011] Specifically, the corrugated strip is made of plastic.

[0012] Specifically, an airbag strip is provided on the inner side of the corrugated strip, one end of the airbag strip is in contact with the inner wall of the cavity, and the other end of the airbag strip is in contact with the outer wall of the corrugated strip of the cavity.

[0013] The beneficial effects of this invention are as follows: When needed, the car warning triangle is taken out of the vehicle, and the crossbar is placed at least 50 meters behind the vehicle. Then, the crossbar is pressed down, causing the deformable support pad to deform. The ball bearings are then pushed upwards by the ground, and the compressed spring bounces back to its original position, causing the left and right tilting frames to unfold and form a triangle with the crossbar. This unfolding eliminates the need for manual unfolding, improving convenience and facilitating quick and easy use of the car warning triangle. After unfolding, the crossbar is released. The special structure of the corrugated strips within the deformable support pad and the recovery of the airbag strips facilitate the return of the deformable support pad to its original position. This also helps the deformable support pad support the crossbar, preventing the ball bearings from contacting the ground due to the downward pressure of the crossbar. Therefore, during normal storage, the car warning triangle is prevented from automatically unfolding. Attached Figure Description

Implementation

[0020] Please see Figures 1-5 A car warning triangle includes a horizontal frame 1, a left tilting frame 3, and a right tilting frame 5. The upper end of the horizontal frame 1 has a groove 2. The left tilting frame 3 is located inside the groove 2, and its left side is rotatably connected to the inside of the groove 2. One side of the left tilting frame 3 has a groove 4, and the right tilting frame 5 is located inside the groove 4. One end of the right tilting frame 5 is rotatably connected to the inside of the groove 4. A rotating shaft 12 is fixed to the upper left side of the groove 2, and the rotating shaft 12 movably passes through the left tilting frame 3. A rotating shaft 13 is fixed to the right side of the groove 4, and one end of the right tilting frame 5 movably passes through the rotating shaft 13. A guide sleeve 16 is located on the upper part of the right tilting frame 5 and on both sides of its front and rear. Each of the components is fixed with a protrusion 24, and a pivot 25 is fixed between the protrusions 24. The pivot 25 is movably connected to the other end of the right tilting frame 5. Reflectors 6 are embedded and fixed at both ends of the cross frame 1, the left tilting frame 3, and the right tilting frame 5. Fluorescent cloth 7 is fixed between the inner sides of the left tilting frame 3 and the right tilting frame 5. The left end of the left tilting frame 3 rotates with the left side of the groove 1 2 through a pivot 1 12, while one end of the right tilting frame 5 rotates with the left tilting frame 3 through a pivot 2 13. This allows the left tilting frame 3 and the right tilting frame 5 to form a triangle with the cross frame 1 after they are unfolded. Then, the reflectors 6 and the fluorescent cloth 7 can be used to warn vehicles approaching from behind.

[0021] The bottom of the groove 1-2 has a guide groove 14. A guide block 18 is slidably connected inside the guide groove 14. The upper part of the guide block 18 extends out of the guide groove 14 and is fixed with a guide sleeve 16. The upper part of the guide sleeve 16 is rotatably connected to the other end of the right tilting frame 5. A spring 17 is connected between the left part of the guide sleeve 16 and the left end of the inner wall of the groove 1-2. The lower end of the guide block 18 has a bottom groove 19. A ball sleeve 21 is slidably connected inside the bottom groove 19. The upper part of the ball sleeve 21 is connected to the bottom of the bottom groove 19. A spring 20 is connected between the two parts. A ball bearing 22 is rolled inside the ball bearing sleeve 21. A rolling groove is formed at the lower end of the ball bearing sleeve 21. The ball bearing 22 is located inside the rolling groove and is rolled in connection with it. The diameter of the lower opening of the rolling groove is larger than the diameter of the ball bearing 22. A retaining hole 23 is formed on the left side of the bottom of the guide groove 14. The ball bearing 22 is inserted into the retaining hole 23. Deformable support pads 8 are fixed on both the left and right sides of the lower end of the cross frame 1. An inner cavity 9 is provided inside the deformable support pad 8. The inner cavity 9 is equipped with a corrugated strip 10, both ends of which are fixed to the inner wall of the inner cavity 9. The corrugated strip 10 is made of plastic. An airbag strip 11 is provided inside the corrugated strip 10. One end of the airbag strip 11 contacts the inner wall of the inner cavity 9, and the other end of the airbag strip 11 contacts the outer wall of the corrugated strip 10. When it is necessary to retract the car warning triangle, the right tilting bracket 5 is pushed to the left, causing the other end of the right tilting bracket 5 to push the guide sleeve 16 to slide to the left and squeeze. Spring 17, at this time, guide block 18 along guide groove 14, ball 22 along the bottom of guide groove 14, then the right tilting frame 5 is stored in the groove 2 4 of left tilting frame 3, then the left tilting frame 3 is rotated and stored in the groove 2 of cross frame 1. When guide sleeve 16 slides to the point where ball 22 corresponds to the locking hole 23, spring 20 in a compressed state pushes ball 22 to engage with locking hole 23, at this time the guide sleeve 16 is limited, so that the entire car warning triangle is in a stored state.

[0022] When needed, take the car warning triangle from the vehicle, then place the crossbar 1 at least 50 meters behind the car. Finally, press down on the crossbar 1. At this point, the deformable support pad 8 will deform. The deformable support pad 8 is made of rubber, and the corrugated strip 10 will also deform slightly. At the same time, the airbag strip 11 will deform, and then the ball bearing 22 will be squeezed upward by the ground and move out of the locking hole 23. At this time, the compressed spring 17 will bounce the guide sleeve 16 to the right and reset. The guide sleeve 16 will drive the other end of the right tilting frame 5, and at the same time, one end of the right tilting frame 5 can push the right side of the left tilting frame 3 upward. When the left tilting frame 3 and right tilting frame 5 are unfolded, they form a triangle with the horizontal frame 1. This unfolding eliminates the need for manual unfolding, improving convenience and facilitating quick and easy use of the car warning triangle. After unfolding, the horizontal frame 1 is released. At this time, the special structure of the corrugated strip 10 in the deformable support pad 8 and the restoration of the airbag strip 11 facilitate the reset of the deformable support pad 8. At the same time, the deformable support pad 8 supports the horizontal frame 1, preventing the deformable support pad 8 from deforming due to the downward pressure of the horizontal frame 1, causing the ball bearing 22 to contact the ground. This prevents the car warning triangle from unfolding automatically when stored and placed.

[0023] A guide post 15 is fixed in the lower part of the groove 2. The guide post 15 is located inside the spring 17. The guide sleeve 16 is movably sleeved on the outside of the guide post 15. When the guide sleeve 16 slides, it can slide along the guide post 15. In this way, the guide post 15 can play a guiding and limiting role for the guide sleeve 16.

[0024] Working principle: When the vehicle breaks down, stalls, or experiences other malfunctions while driving, remove the car warning triangle from the vehicle. Then, place the crossbar 1 at least 50 meters behind the vehicle and press it down slightly. At this point, the deformable support pad 8 will deform, and the corrugated strip 10 will also deform slightly. Simultaneously, the airbag strip 11 will deform, and the ball bearing 22 will be pushed upward by the ground and move out of the locking hole 23. At this time, the compressed spring 17 will bounce the guide sleeve 16 to the right and reset. The guide sleeve 16 will move the other end of the right tilting frame 5, and at the same time, one end of the right tilting frame 5 can push the right side of the left tilting frame 3 upward. At this time, the left tilting frame 3 and the right tilting frame 5 will unfold and form a triangle with the crossbar 1. This unfolding does not require manual unfolding, thus improving convenience and facilitating quick use of the car warning triangle. After unfolding, release the crossbar 1. At this time, through the special structure of the corrugated strip 10 in the deformable support pad 8 and the airbag strip 11, The restoration of the deformation support pad 8 facilitates its repositioning and also helps the deformation support pad 8 support the cross frame 1, preventing the deformation support pad 8 from deforming due to the downward pressure of the cross frame 1, causing the ball bearing 22 to contact the ground. This prevents the car warning triangle from automatically unfolding during normal storage. When the car warning triangle needs to be stored, pushing the right tilting frame 5 to the left causes the other end of the right tilting frame 5 to push the guide sleeve 16 to slide to the left and compress the spring 17. At this time, the guide block 18 moves along the guide groove 14, and the ball bearing 22 rolls along the bottom of the guide groove 14. Then, the right tilting frame 5 is stored in the groove 4 of the left tilting frame 3. Then, the left tilting frame 3 is rotated and stored in the groove 2 of the cross frame 1. When the guide sleeve 16 slides until the ball bearing 22 corresponds to the locking hole 23, the compressed spring 20 pushes the ball bearing 22 to engage with the locking hole 23. At this time, the guide sleeve 16 is limited, so that the entire car warning triangle is in a stored state, making it more convenient to use.
