[0014] 1. The present invention provides a directional deceleration device and a method for using the same. The deceleration plate and the auxiliary plate are rotatably arranged on a mounting seat. When a vehicle impacts the deceleration plate, the movable pin is clamped by the cooperation between the movable pin shaft and the left recessed groove and the right recessed groove, so that the deceleration plate and the auxiliary plate cooperate with the mounting seat to form a deceleration belt, thereby achieving deceleration of the moving vehicle.

[0015] 2. By utilizing the positions of the left and right recessed grooves relative to the deceleration pin shaft hole and the auxiliary pin shaft hole, when the auxiliary plate is pressed, the movable pin shaft can be pushed into the deceleration pin shaft hole, thereby causing the deceleration plate and the auxiliary plate to rotate relative to each other into a horizontal state, and the deceleration plate and the auxiliary plate rotate into the mounting seat to avoid interfering with the passage of vehicles that do not need to be decelerated.

[0031] The deceleration plate 2 and the auxiliary plate 3 are supported by an elastic support structure so that they can maintain an inclined state, and the mounting seat 1, the deceleration plate 2 and the auxiliary plate 3 form a triangular structure; the connection position of the left active pin shaft hole 15 and the left concave groove 17 and the connection position of the right active pin shaft hole 16 and the right concave groove 18 are utilized so that the active pin shaft 4 located in the left concave groove 17 and the right concave groove 18 can only be pushed in one direction to realize the storage of the deceleration plate 2 and the auxiliary plate 3; when the deceleration plate 2 is pushed downward and rotated, the active pin shaft 4 can be pushed downward and rotated downward, so that ... 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 stuck state at this time, that is, the speed reducer 2 and the auxiliary plate 3 cannot rotate relative to each other and cannot be stored; when the auxiliary plate 3 is pushed downward and rotated, the movable pin 4 can be located in the left movable pin hole 15 and the right movable pin hole 16, and the movable pin 4 can move arbitrarily in 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 realizing the storage of the speed reducer 2 and the auxiliary plate 3.

[0032] The rotating ends of the deceleration plate 2 and the auxiliary plate 3 are located at the inner top of the groove body of the mounting seat 1. When the deceleration plate 2 and the auxiliary plate 3 are stored, the movable ends of the deceleration plate 2 and the auxiliary plate 3 can be rotated to the inner bottom of the groove body of the mounting seat 1.

[0033] like Figure 1-3As shown, the rotational installation of the deceleration plate 2 and the auxiliary plate 3 is realized. The two ends of the side wall of the mounting seat 1 are respectively provided with a deceleration pin shaft hole 13 and an auxiliary pin shaft hole 14, and the deceleration pin shaft hole 13 and the auxiliary pin shaft hole 14 are respectively connected with the deceleration pin shaft 5 and the auxiliary pin shaft 6.

After the left mounting shaft hole 20 and the right mounting shaft hole 21 on the deceleration plate 2 and the auxiliary plate 3 are aligned with the deceleration pin shaft hole 13 and the auxiliary pin shaft hole 14, the deceleration pin shaft 5 and the auxiliary pin shaft 6 are inserted to realize the rotational installation of the deceleration plate 2 and the auxiliary plate 3.

[0034] like Figure 6-9 As shown. The elastic support structure includes a deceleration plate spring 7 and an auxiliary plate spring 8, which are respectively mounted on the deceleration pin 5 and the auxiliary pin 6. The top surfaces of the side walls of the deceleration plate 2 and the auxiliary plate 3 are respectively connected with a left spring baffle 9 and a right spring baffle 10. The movable ends of the deceleration plate spring 7 and the auxiliary plate spring 8 are both provided with extension sections.

By respectively installing the left spring baffle 9 and the right spring baffle 10 on the deceleration plate 2 and the auxiliary plate 3, compared with the form of welding the spring ends, the contact area and thickness with the deceleration plate spring 7 and the auxiliary plate spring 8 can be increased, and the force-bearing area and the load-bearing quality can be improved.

[0035] like Figure 1 , Figure 6 , Figure 7 and Fig.13 As shown. A raised positioning step 22 is provided in the middle of the outer circumference of the movable pin shaft 4, and the opposite outer end walls of the raised positioning step 22 are respectively fitted with the opposite side walls of the deceleration plate 2 and the auxiliary plate 3, and the outer diameter of the raised positioning step 22 is greater than the width of the deceleration pin shaft hole 13 and the auxiliary pin shaft hole 14. By providing the raised positioning step 22 in the middle of the movable pin shaft 4, the axial sliding of the movable pin shaft 4 can be avoided, while maintaining the stable connection between the movable pin shaft 4 and the deceleration plate 2 and the auxiliary plate 3.

[0036] like Fig.11 and Fig.12 As shown. The separated ends of the left concave groove 17 and the right concave groove 18 are respectively provided with back plates for limiting the two ends of the movable pin shaft 4. The two end walls of the movable pin shaft 4 are respectively fitted with the bottom surfaces of the left concave groove 17 and the right concave groove 18, so as to maintain the position of the movable pin shaft 4 stable in the initial state and adapt to the subsequent movement of the speed reducer 2 or the auxiliary plate 3 in the left movable pin shaft hole 15 or the right movable pin shaft hole 16 after being pressed down.

[0037] like Figure 3 As shown, in order to facilitate the installation and fixation of the mounting seat 1, the top groove of the mounting seat 1 is provided with mounting holes 19, and the mounting holes 19 are evenly distributed on the edge of the mounting seat 1.

[0039] As a preferred embodiment of the present invention, the separated end walls of the deceleration plate 2 and the auxiliary plate 3 are respectively fitted with the inner side walls of the top groove of the mounting seat 1. Since the deceleration plate 2 and the auxiliary plate 3 are located on both sides of the groove, after ensuring that the outer side walls of the deceleration plate 2 and the auxiliary plate 3 are fitted with the inner side walls of the groove, it can be ensured that the deceleration plate 2 will not deviate and can rotate stably.

[0040] like Figure 6 and Figure 7 As shown. The two ends of the opening of the top groove of the mounting seat 1 are respectively provided with arc-shaped cavities for accommodating the rotating ends of the deceleration plate 2 and the auxiliary plate 3. The rotating ends of the deceleration plate 2 and the auxiliary plate 3 are accommodated by the arc-shaped cavity.

When a vehicle comes from the left, the speed brake 2 is subjected to force, overcoming the elastic force of the left spring baffle 9, and the auxiliary plate 3 rotates clockwise, driving the movable pin 4 in the left recessed groove 17 to move downward, so that the movable pin 4 is stuck at the top of the left recessed groove 17 and the bottom of the right recessed groove 18 and cannot move further. The speed brake 2 and the auxiliary plate 3 are stationary at the same time due to the blocking resistance of the movable pin 4, and the directional speed reduction device is in the shape of a speed reduction belt.
