Description

Technical Field

[0001] This invention relates to the field of road traffic safety technology, specifically a one-way deceleration device and its usage method. Background Technology

[0002] Traffic roads are constrained by many factors such as altitude, topography, human environment, road shape, and traffic safety. Speed ​​bumps are often installed in special locations and sections to force people to slow down, while some sections of the road do not require slowing down when going uphill. For example, when entering a side road from a main road or on a long downhill section, where slowing down is not required on the uphill section, people have to slow down and start again because of speed bumps, resulting in wasted time and energy. Summary of the Invention

[0003] The technical problem to be solved by this invention is that conventional speed bumps cause vehicles that do not need to slow down to decelerate, resulting in a waste of time and energy.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a one-way deceleration device, including a mounting base, a deceleration plate and an auxiliary plate horizontally rotatably connected to both ends of the top groove of the mounting base, and an elastic support structure supporting the deceleration plate and the auxiliary plate in an inclined state. The deceleration plate and the auxiliary plate are located on both sides of the groove. The movable ends of the deceleration plate and the auxiliary plate are respectively provided with a strip-shaped left movable pin hole and a right movable pin hole. A left recessed groove is provided at the bottom of the top of the left movable pin hole, and a right recessed groove is provided at the top of the top of the right movable pin hole. A movable pin is connected between the left recessed groove and the right recessed groove. The sum of the distance from the rotating end of the deceleration plate to the left movable pin hole and the distance from the auxiliary plate to the right movable pin hole is less than the length of the groove.

[0005] Preferably, the mounting base has a reduction pin hole and an auxiliary pin hole at both ends of its side wall, and a reduction pin and an auxiliary pin are connected in the reduction pin hole and the auxiliary pin hole, respectively. The reduction plate has a left mounting shaft hole at its bottom end, through which the reduction pin is rotatably connected. The auxiliary plate has a right mounting shaft hole at its bottom end, through which the auxiliary pin is rotatably connected.

[0006] Preferably, the elastic support structure includes a deceleration plate spring and an auxiliary plate spring, which are respectively mounted on the deceleration pin and the auxiliary pin. The top sidewalls of the deceleration plate and the auxiliary plate are respectively connected to a left spring baffle and a right spring baffle. The movable ends of the deceleration plate spring and the auxiliary plate spring are provided with extension sections. The lower movable ends of the deceleration plate spring and the auxiliary plate spring abut against the opposite inner sidewalls of the top groove of the mounting base, and the upper movable ends abut against the left spring baffle and the right spring baffle, respectively.

[0007] Preferably, a raised positioning step is provided in the middle of the outer peripheral surface of the movable pin, and the opposite outer end walls of the raised positioning step are respectively in contact with the opposite side walls of the deceleration plate and the auxiliary plate. The outer diameter of the raised positioning step is larger than the width of the deceleration pin hole and the auxiliary pin hole.

[0008] Preferably, the left and right recessed grooves are respectively provided with back plates that limit the two ends of the movable pin.

[0009] Preferably, the mounting base has mounting holes in the top groove, and the mounting holes are evenly distributed on the edge of the mounting base.

[0010] Preferably, a drainage ditch is provided in the middle of the top groove of the mounting base, and a drainage hole is provided on the side wall of the mounting base, with the drainage hole communicating with both ends of the drainage ditch.

[0011] Preferably, the opposite end walls of the speed reducer and the auxiliary plate are respectively attached to the inner sidewall of the top groove of the mounting base.

[0012] Preferably, the top groove of the mounting base has arc-shaped cavities at both ends for accommodating the rotating ends of the speed reducer and the auxiliary plate.

[0013] A method of using a one-way speed reduction device includes the following steps:

[0014] S1. Installation: According to the road width, multiple directional deceleration devices are spliced ​​and assembled. The mounting base is fixed on the road surface, and then the deceleration plate and auxiliary plate are rotatably installed on the mounting base and the movable pin is connected.

[0015] S2. When a vehicle approaches from the right, the auxiliary plate is subjected to force and overcomes the elastic force of the right spring baffle. The auxiliary plate rotates counterclockwise, causing the movable pin to move downward in the right recess of the auxiliary plate and simultaneously move downward along the left recess. The movable pin enters the left movable pin hole and the right movable pin hole, while overcoming the elastic force of the deceleration plate spring, causing the deceleration plate to rotate clockwise. Finally, the deceleration plate and the auxiliary plate rotate to the top groove of the mounting base, resulting in a level road condition.

[0016] S3. When a vehicle approaches from the left, the speed reducer is subjected to force, which overcomes the elastic force of the left spring baffle. The auxiliary plate rotates clockwise and drives the movable pin in the left recess to move downward. This causes the movable pin to get stuck at the top of the left recess and the bottom of the right recess and cannot move further. The speed reducer and the auxiliary plate stop simultaneously due to the resistance of the movable pin. The directional speed reduction device is in the shape of a speed bump.

[0017] 1. This invention provides a directional deceleration device and its usage method. By rotating a deceleration plate and an auxiliary plate on the mounting base, when a vehicle impacts the deceleration plate, the movable pin is locked by the cooperation of the movable pin with the left and right recessed grooves, so that the deceleration plate and the auxiliary plate cooperate with the mounting base to form a deceleration band, thereby decelerating the moving vehicle.

[0018] 2. By utilizing the positions of the left and right recessed grooves relative to the deceleration pin hole and the auxiliary pin hole, when the auxiliary plate is pressed, the movable pin can be pushed into the deceleration pin hole, thereby causing the deceleration plate and the auxiliary plate to rotate relative to each other into a horizontal position. The deceleration plate and the auxiliary plate rotate into the mounting base, avoiding interference with the passage of vehicles that do not need to decelerate. Attached Figure Description

Detailed Implementation

[0034] like Figures 1-13 As shown, the present invention provides a one-way deceleration device, including a mounting base 1, a deceleration plate 2 and an auxiliary plate 3 horizontally rotatably connected to both ends of the top groove of the mounting base 1, and an elastic support structure supporting the deceleration plate 2 and the auxiliary plate 3 in an inclined state. The deceleration plate 2 and the auxiliary plate 3 are located on both sides of the groove. The movable ends of the deceleration plate 2 and the auxiliary plate 3 are respectively provided with a strip-shaped left movable pin hole 15 and a right movable pin hole 16. A left recessed groove 17 is provided at the bottom of the top of the left movable pin hole 15, and a right recessed groove 18 is provided at the top of the top of the right movable pin hole 16. A movable pin 4 is connected between the left recessed groove 17 and the right recessed groove 18. The sum of the distance from the rotating end of the deceleration plate 2 to the left movable pin hole 15 and the distance from the auxiliary plate 3 to the right movable pin hole 16 is less than the length of the groove.

[0035] The speed reducer 2 and auxiliary plate 3 are supported by an elastic support structure, allowing them to maintain an inclined state. The mounting base 1, speed reducer 2, and auxiliary plate 3 form a triangular structure. Utilizing the connection positions of the left movable pin hole 15 and the left recess 17, and the right movable pin hole 16 and the right recess 18, the movable pin 4 located in the left and right recesses 17 and 18 can only be pushed in one direction, thus accommodating the speed reducer 2 and auxiliary plate 3. When the speed reducer 2 is pushed downwards, the movable pin 4... Located at the top of the left recessed groove 17 and the bottom of the right recessed groove 18, the movable pin 4 is in a jammed state, meaning that the speed reducer 2 and the auxiliary plate 3 cannot rotate relative to each other and cannot be stored. However, when the auxiliary plate 3 is pushed downwards and rotated, the movable pin 4 can be positioned in the left movable pin hole 15 and the right movable pin hole 16. The movable pin 4 can move freely within the left movable pin hole 15 and the right movable pin hole 16, thereby maintaining the rotation of the speed reducer 2 and the auxiliary plate 3 and enabling the storage of the speed reducer 2 and the auxiliary plate 3.

[0036] The rotating ends of the speed reducer 2 and the auxiliary plate 3 are located at the top of the inner cavity of the mounting base 1. When the speed reducer 2 and the auxiliary plate 3 are stored, the movable ends of the speed reducer 2 and the auxiliary plate 3 can be rotated to the bottom of the inner cavity of the mounting base 1.

[0037] like Figures 1-3 As shown, to achieve the rotatable installation of the speed reducer 2 and the auxiliary plate 3, the mounting base 1 has a speed reduction pin hole 13 and an auxiliary pin hole 14 at both ends of its side wall. A speed reduction pin 5 and an auxiliary pin 6 are respectively connected to the speed reduction pin hole 13 and the auxiliary pin hole 14. The bottom end of the speed reducer 2 has a left mounting shaft hole 20, through which the speed reduction pin 5 is rotatably connected. The bottom end of the auxiliary plate 3 has a right mounting shaft hole 21, through which the auxiliary pin 6 is rotatably connected. After aligning the left mounting shaft hole 20 and the right mounting shaft hole 21 on the speed reducer 2 and the auxiliary plate 3 with the speed reduction pin hole 13 and the auxiliary pin hole 14 respectively, the speed reduction pin 5 and the auxiliary pin 6 are inserted, thus achieving the rotatable installation of the speed reducer 2 and the auxiliary plate 3.

[0038] like Figures 6-9 As shown. The elastic support structure includes a reduction plate spring 7 and an auxiliary plate spring 8, which are respectively mounted on the reduction pin 5 and the auxiliary pin 6. A left spring baffle 9 and a right spring baffle 10 are respectively connected to the top surface of the side walls of the reduction plate 2 and the auxiliary plate 3. Both the reduction plate spring 7 and the auxiliary plate spring 8 have extended sections at their movable ends. The lower movable ends of the reduction plate spring 7 and the auxiliary plate spring 8 abut against the opposite inner side walls of the top groove of the mounting base 1, while the upper movable ends abut against the left spring baffle 9 and the right spring baffle 10, respectively. By installing the left spring baffle 9 and the right spring baffle 10 on the reduction plate 2 and the auxiliary plate 3, respectively, compared to welding the spring ends, the contact area and thickness with the reduction plate spring 7 and the auxiliary plate spring 8 can be increased, thereby improving the force-bearing area and load-bearing capacity.

[0039] like Figure 1 , Figure 6 , Figure 7 and Figure 13 As shown, a raised positioning step 22 is provided in the middle of the outer peripheral surface of the movable pin 4. The opposite outer end walls of the raised positioning step 22 are respectively in contact with the opposite side walls of the speed reduction plate 2 and the auxiliary plate 3. The outer diameter of the raised positioning step 22 is larger than the width of the speed reduction pin hole 13 and the auxiliary pin hole 14. By providing a raised positioning step 22 in the middle of the movable pin 4, axial sliding of the movable pin 4 can be avoided, while maintaining a stable connection between the movable pin 4 and the speed reduction plate 2 and the auxiliary plate 3.

[0040] like Figure 11 and Figure 12As shown. The left recessed groove 17 and the right recessed groove 18 are respectively provided with back plates that limit the two ends of the movable pin 4. The two end walls of the movable pin 4 are respectively in contact with the bottom surfaces of the left recessed groove 17 and the right recessed groove 18, maintaining the position of the movable pin 4 in the initial state, and can adapt to the subsequent movement of the deceleration plate 2 or the auxiliary plate 3 in the left movable pin hole 15 or the right movable pin hole 16 after being pressed down.

[0041] like Figure 3 As shown, to facilitate the installation and fixing of the mounting base 1, mounting holes 19 are provided in the top groove of the mounting base 1, and the mounting holes 19 are evenly distributed on the edge of the mounting base 1.

[0042] like Figure 3 As shown, to achieve automatic drainage of rainwater from the mounting base 1, a drainage ditch 12 is provided in the middle of the top groove of the mounting base 1, and a drainage hole 11 is provided on the side wall of the mounting base 1, which is connected to both ends of the drainage ditch 12.

[0043] In a preferred embodiment of the present invention, the opposite end walls of the speed reducer 2 and the auxiliary plate 3 are respectively fitted to the inner sidewalls of the top groove of the mounting base 1. Since the speed reducer 2 and the auxiliary plate 3 are located on both sides of the groove, ensuring that the outer sidewalls of the speed reducer 2 and the auxiliary plate 3 are fitted to the inner sidewalls of the groove ensures that the speed reducer 2 will not shift and can rotate stably.

[0044] like Figure 6 and Figure 7 As shown. At both ends of the opening of the top groove of the mounting base 1, arc-shaped cavities are respectively provided to accommodate the rotating ends of the speed reducer 2 and the auxiliary plate 3. By accommodating the rotating ends of the speed reducer 2 and the auxiliary plate 3 through the arc-shaped cavities, even when the speed reducer 2 and the auxiliary plate 3 are pushed outwards by the speed reducer spring 7 and the auxiliary plate spring 8, the speed reducer 2 and the auxiliary plate 3 are limited by the arc-shaped cavities, facilitating the installation of the movable pin 4 and the connection between the speed reducer 2 and the auxiliary plate 3 via the movable pin 4.

[0045] A method of using a one-way speed reduction device includes the following steps:

[0046] S1. Installation: According to the road width, multiple directional deceleration devices are spliced ​​and assembled. The mounting base 1 is fixed on the road surface, and the deceleration plate 2 and auxiliary plate 3 are rotatably installed on the mounting base 1, and the movable pin 4 is connected.

[0047] S2. When a vehicle approaches from the right, the auxiliary plate 3 is subjected to force and overcomes the elastic force of the right spring baffle 10. The auxiliary plate 3 rotates counterclockwise, causing the movable pin 4 to move downward in the right recess 18 of the auxiliary plate 3 and simultaneously move downward along the left recess 17. The movable pin 4 enters the left movable pin hole 15 and the right movable pin hole 16, while overcoming the elastic force of the deceleration plate spring 7, causing the deceleration plate 2 to rotate clockwise. Finally, the deceleration plate 2 and the auxiliary plate 3 rotate into the top groove of the mounting base 1, resulting in a level road condition.

[0048] S3. When a vehicle approaches from the left, the speed reduction plate 2 is subjected to force, which overcomes the elastic force of the left spring baffle 9. The auxiliary plate 3 rotates clockwise and drives the movable pin 4 in the left recess 17 to move downward. This causes the movable pin 4 to be stuck at the top of the left recess 17 and the bottom of the right recess 18 and cannot move further. The speed reduction plate 2 and the auxiliary plate 3 stop simultaneously due to the resistance of the movable pin 4. The directional speed reduction device is in the shape of a speed reduction band.
