[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1:

[0031] like Figure 1 As shown, a speed-controlled adjustable speed reduction belt comprises a main body 1, an elastic component 2 and a speed-controlling component 3; the main body 1 can be lifted and displaced relative to the ground, and the elastic component 2 elastically supports the main body 1; the speed-controlling component 3 can limit the downward displacement of the main body 1; the speed-controlling component 3 comprises a driving member 31, a driven member 32 and a braking member 33; the driving member 31 is in the shape of an elongated strip, and one end of the driving member 31 is fixed under the main body 1; the driven member 32 receives the driving member 31 and converts the linear reciprocating motion of the driving member 31 into a two-way rotation, and the driven member 32 moves synchronously with the driving member 31; the braking member 33 rotates synchronously with the driven member 32, and the braking member 33 is used to control the driven member 32 to be in a two-way rotatable state or a unidirectional non-rotatable state.

[0032] When the vehicle passes over the speed bump, it presses on the main body 1, the main body 1 descends, the driving member 31 moves downward, drives the driven member 32 to rotate forward synchronously, and the brake member 33 rotates forward synchronously; when the vehicle leaves the speed bump, the main body 1 rises under the action of the elastic member 2, the driving member 31 moves upward, drives the driven member 32 to rotate in the opposite direction synchronously, and the brake member 33 rotates in the opposite direction synchronously. When the driving member 31 moves downward too fast, the brake member 33 will play a braking role, so that the driven member cannot move forward, and the driving member 31 cannot continue to move downward, and the main body 1 cannot descend.

[0033] Furthermore, if Figure 3 As shown, the driving member 31 is a spiral rod, that is, a rod with a spiral surface. In this embodiment, a twisted long strip rod is used, and a twisted square rod can also be used. The driven member 32 is a hollow cylinder. A through hole 321 is provided on one end surface of the driven member 32. The shape of the through hole 321 is the same as the cross-sectional shape of the driving member 32. A larger through hole can be provided at the other end of the driven member 32, or it can be open, or the length of the driven member 32 is greater than the maximum displacement of the driving member 31, so that the movement of the driving member 31 will not be restricted by the driven member 32.

[0034] Furthermore, if Figure 8 , Fig. 9As shown, the brake member 33 includes a brake disc 334, a pawl 331 and a ratchet ring 332 with ratchet teeth inside. The brake disc 334 is fixed to the other end of the driven member 32 and is coaxial with the driven member 32. The pawl 331 is rotatably arranged on the outer edge of the disc surface of the brake disc 334. The end of the pawl 331 can extend into the tooth groove of the ratchet ring 332 and put the driven member 32 in a one-way non-rotatable state. A first spring 333 is arranged between the pawl 331 and the brake disc 334. The first spring 333 pulls the end of the pawl 331 in a direction away from the ratchet ring 332. In this embodiment, the length of the driven member 32 is greater than the maximum displacement of the driving member 31, and a larger through hole can also be arranged in the middle of the brake disc 334 so that the driving member 31 can pass through the through hole.

[0035] Furthermore, if Figure 4 As shown, the main body 1 includes a main board 11, and the main board 11 is hinged with side panels 12 on both sides, and a side panel sleeve 13 is hinged on the road surface. The two side panels 12 are respectively inserted into the side panel sleeve 13, and a pulley 14 is provided below the side panel 12. A slide rail 15 corresponding to the pulley 14 is provided in the side panel sleeve 13. The pulley 14 and the slide rail 15 make the side panel enter and exit the side panel sleeve more smoothly. The elastic component 2 is fixed below the main board 11, and the main board 11 can compress the elastic component 2 to move downward. When the vehicle does not pass, the main board 11 is supported by the elastic component, and the end of the side panel 12 is inserted into the side panel sleeve 13. When the vehicle passes, the main board 11 moves downward, and the side panel 12 slides to both sides and is inserted deep into the side panel sleeve 13. In this embodiment, the side panel 12 can be fully inserted into the side panel sleeve 13, and the main board 11 can be completely lowered to the ground height, so that the vibration of the speed reduction belt to the vehicle with a lower speed can be minimized.

[0036] Furthermore, if Figure 5 As shown, the elastic component 2 includes a support rod 21 and a sleeve 22. The sleeve 22 is fixed in the road. One end of the support rod 21 is fixedly connected to the main body 1, and the other end of the support rod 21 extends into the sleeve 22. A second spring 23 is provided between the support rod 21 and the sleeve 22. The support rod 21 can move into the sleeve 22 and compress the second spring 23.

[0037] like Figure 2 As shown, the main body 1, part of the elastic device 2 and part of the driving member 31 are located above the road surface, and the rest is located below the road surface. A road groove is set on the road surface, and the ratchet ring 332 is fixed in the road groove through a bracket. A bearing is set on the driven member 32, which is fixed to the bracket or embedded structure in the road groove through the bearing. An embedded part is buried in the road surface below the main board 11, and a thread is set on the outer side of the sleeve 22. The sleeve 22 is fixed in the embedded part through a thread. The upper end surface of the sleeve 22 is flush with the road surface or slightly lower than the road surface, so that the main board 11 can be lowered to a height closer to the road surface. Embedded parts are buried on both sides of the main board 11, which are hinged to the side plate sleeve 13.

[0038] like Figure 6 As shown, when the vehicle passes through the speed bump at high speed, the main body 1 drops rapidly, driving the driving member 31 to drop rapidly, thereby causing the driven member 32 and the brake disc 334 to rotate rapidly, as shown in FIG. Figure 8 As shown in FIG. 1 , the faster the rotation speed, the greater the centrifugal force on the pawl 331. The faster the rotation speed, the more the pawl 331 opens outward and extends into the tooth groove of the ratchet wheel 332. The pawl 331 is stuck in the ratchet wheel 332, so that the brake disc 334 cannot rotate, and the driving member cannot continue to descend, and the main body 1 remains in the arched position; Figure 7 As shown, when the vehicle passes through the speed reduction belt at a low speed, the main body 1 descends slowly, the driving member 31 descends slowly, and the driven member 32 and the brake disc 334 rotate slowly. Fig. 9 As shown, the pawl will not rotate to extend into the ratchet ring 332, and the main body 1 will continue to drop to the ground level as the wheel passes, and the vehicle will run smoothly. Fig.10 As shown, the main body 1 is lowered to the ground height, and the elastic component 2 is compressed. When the vehicle drives away, the elastic component 2 bounces the main body 1 upward to restore the arched state.

[0039] Embodiment 2:

[0040] like Fig.11 , Fig.12 As shown, different from the first embodiment, the brake member 33 comprises a brake disc 334, a pawl 331 and a ratchet ring 332 with ratchet teeth inside, the pawl 331 is fixed to the outer edge of the brake disc 334, the end of the pawl 331 can extend into the tooth groove of the ratchet ring 332 and make the brake disc 334 in a one-way non-rotatable state, the brake disc 334 is coaxially fixed with a gear 335, the outer edge of the follower 32 is provided with a transmission tooth 322, the transmission tooth 322 is meshed with the gear 335, a first spring 333 is provided between the pawl 331 and the brake disc 334, and the first spring 333 pulls the end of the pawl 331 in a direction away from the ratchet ring 332. In this embodiment, the bottom of the follower 32 is open, which does not affect the movement of the driving member 31, and the transmission ratio between the follower 32 and the brake member 33 can be adjusted through the gear 335 and the transmission tooth 322 to adapt to different speed limit standards on different roads.

[0041] The brake disc 34 and the gear 335 are fixedly connected via a coaxial cylinder, on which a bearing is provided, and fixed to a bracket or a pre-buried structure in the road groove via the bearing.
