Description

Technical Field

[0001] The utility model relates to the technical field of speed bumps, and in particular to a highway speed bump. Background Art

[0002] Speed ​​bumps are also generally called speed reduction ridges. They usually refer to bumps designed on the road to control vehicle speed. When a vehicle passes over the speed bumps, it will experience a certain vertical vibration, thus forcing the vehicle to slow down.

[0003] At present, speed bumps with non-Newtonian fluids inside have appeared on the market. With the help of the characteristics of non-Newtonian fluids, drivers can actively slow down to ensure the comfort of passengers and reduce the bumpy feeling inside the vehicle. However, once the speed bump is damaged, the non-Newtonian fluid inside will flow out of the speed bump, affecting road hygiene and even causing traffic accidents. Utility Model Content

[0004] The utility model provides a highway speed bump, which solves the problem in the related art that a non-Newtonian fluid flows out of the speed bump when the speed bump is damaged.

[0005] The technical solution of the utility model is as follows:

[0006] A highway speed bump comprises a speed bump body and a mounting groove for mounting the speed bump body, wherein the speed bump body is made of elastic material, a buffer structure is arranged between the mounting groove and the speed bump body, the buffer structure comprises a buffer belt and a plurality of buffer components, the buffer belt is located between the speed bump body and each buffer component; each buffer component comprises a linkage rod and a buffer cylinder, the linkage rod is slidably connected to the buffer cylinder, the buffer belt is fixedly connected to one end of each linkage rod away from the buffer cylinder, an elastic member is arranged between the buffer belt and each buffer cylinder, and a non-Newtonian fluid is filled in the buffer cylinder.

[0007] Furthermore, the buffer belt includes a plurality of buffer bodies, each of which is arranged in sequence along a linear direction, and each of the buffer bodies is fixedly connected to an end of each linkage rod away from the buffer cylinder in a one-to-one correspondence.

[0008] Furthermore, one end of the speed bump body away from the buffer body is an arched structure, and one end of the buffer body close to the speed bump body is an arc-shaped structure.

[0009] Furthermore, a plurality of sealing rings are provided between the linkage rod and the buffer cylinder, and the sealing rings are arranged in sequence along a linear direction.

[0010] Furthermore, an auxiliary pressure plate is provided at one end of the linkage rod away from the buffer belt, and the auxiliary pressure plate is a conical structure.

[0013] Furthermore, a plurality of reinforcing ribs are provided between the connecting plate and the linkage rod, and the reinforcing ribs are evenly distributed around the circumference of the linkage rod.

[0014] The working principle and beneficial effects of the utility model are:

[0015] 1. The speed bump body in the utility model is installed in a mounting groove opened on the ground, and the speed bump body is made of elastic material, that is, when a vehicle passes through the speed bump body, the speed bump body will be deformed to a certain extent, so that the speed bump body contacts the buffer structure between the mounting groove and the speed bump body, and then the pressure on the speed bump body caused by the vehicle passing through the speed bump body is buffered by the buffer structure.

[0016] 2. The buffer structure of the present invention includes a buffer belt, a linkage rod, and a buffer cylinder. The linkage rod is slidably connected in the buffer cylinder, and the buffer belt is located between the speed bump body and the linkage rod.

With the help of the characteristics of the non-Newtonian fluid, the driver can actively reduce the speed to avoid excessive bumps inside the vehicle when the vehicle passes through the speed bump body.

[0017] 3. The non-Newtonian fluid in the novel method is located in the buffer cylinder rather than in the speed bump body, so as to prevent the non-Newtonian fluid inside from flowing out of the speed bump body when the speed bump body is damaged, thereby affecting road hygiene and even causing traffic accidents.

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-2 As shown, this embodiment proposes a highway speed bump, which mainly includes a speed bump body 1 and a mounting groove 2 for mounting the speed bump body 1. The speed bump body 1 is fixedly connected to the mounting groove 2. The speed bump body 1 is made of elastic material. A buffer structure 3 is provided between the mounting groove 2 and the speed bump body 1. That is, when a vehicle passes through the speed bump body 1, a certain pressure will be applied to the speed bump body 1, causing the speed bump body 1 to deform, thereby triggering the buffer structure 3. With the buffering effect of the buffer structure 3, the bumpy feeling of the vehicle when passing through the speed bump body 1 is reduced.

[0027] The elastic material constituting the speed bump body 1 is preferably a wear-resistant and high-temperature-resistant elastic material such as fluororubber, which fully guarantees the service life of the embodiment.

[0028] The buffer structure 3 in this embodiment includes a buffer belt 31 and a plurality of buffer components 32. The buffer belt 31 is located between the speed bump body 1 and the buffer components 32. The buffer belt 31 supports the speed bump body 1. When the speed bump body 1 is deformed by force, the buffer belt 31 is squeezed. To prevent the buffer belt 31 from deforming by force, the buffer belt 31 is slidably connected to the mounting groove 2. That is, when the buffer belt 31 is subjected to force, part of the force it bears is converted into a force driving it to move toward the buffer components 32, thereby consuming part of the pressure of the buffer components. The impact assembly 32 includes a linkage rod 321 and a buffer cylinder 322. The buffer belt 31 is fixedly connected to one end of each linkage rod 321 away from the buffer cylinder 322, that is, the buffer belt 31 will drive the linkage rod 321 to move together during the movement, and because the linkage rod 321 is slidably connected to the buffer cylinder 322, and the buffer cylinder 322 is filled with a non-Newtonian fluid 4, as the buffer belt 31 moves, the linkage rod 321 gradually comes into contact with the non-Newtonian fluid 4, and due to the particularity of the non-Newtonian fluid 4, the following two results will occur:

[0029] First, when a vehicle passes by quickly, because the vehicle maintains a relatively high speed, a relatively large impact force will be generated when the vehicle contacts the speed bump body 1. This impact force is transmitted to the linkage rod along the buffer strip 31, causing the linkage rod 321 to quickly hit the non-Newtonian fluid 4, causing the non-Newtonian fluid 4 to solidify under force, thereby restricting the linkage rod 321 from continuing to move downward, so that in this embodiment, there are still relatively large protrusions on the ground, causing severe bumps when the vehicle passes through this embodiment quickly, thereby forcing the driver to passively decelerate.

[0030] Second, the vehicle passes slowly. Because the vehicle passes through the speed bump body 1 at a relatively low speed, the speed bump body 1 is slowly deformed, thereby pushing the buffer strip 31, causing the linkage rod 321 to slowly sink into the non-Newtonian fluid, and as the linkage rod 321 descends, the buffer strip 31 also gradually descends, so that when the vehicle passes by, the present embodiment only retains small protrusions on the ground, or even no protrusions, so that the vehicle passes through the present embodiment almost without being bumped.

[0031] Elastic members 9 are provided between the buffer belt 31 and each buffer cylinder 322, and the two ends of the elastic members 9 respectively fix the buffer belt 31 and the buffer cylinder 322. The elastic members 9 in this embodiment are preferably compression springs, so that after the buffer belt 31 is moved by an external force, it can be reset with the help of the elastic potential energy of the elastic members 9, and at the same time, it can also buffer a part of the external force with the help of the elastic potential energy of the elastic members 9, killing two birds with one stone, and fully improving the practicality of this embodiment. If necessary, a plurality of elastic members 9 can be provided, and the elastic members 9 can be evenly distributed around the buffer cylinder 322 to make the movement of the buffer belt 31 more stable.

[0032] At the same time, since the non-Newtonian fluid 4 in this embodiment is placed inside the buffer cylinder 322, and the buffer cylinder 322 is placed inside the mounting groove 2, and the mounting groove 2 itself is opened on the ground, in this case, even if the buffer cylinder 322 (the container of the non-Newtonian fluid 4) is compressed and damaged, the non-Newtonian fluid 4 is difficult to flow to the ground, thereby avoiding the presence of the non-Newtonian fluid 4 in this embodiment affecting road hygiene and even causing traffic accidents.

[0033] like Figure 3-4 As shown, the linkage rod 321 in this embodiment is provided with a connecting disk 6 at one end close to the buffer belt 31, and the connecting disk 6 and the linkage rod 321 are integrally formed. A plurality of connecting holes 61 are provided on the connecting disk 6, and a plurality of fixing holes 3111 are provided on the buffer belt 31. Each connecting hole 61 corresponds to each fixing hole 3111 one by one, and a fixing member 7 is provided between each fixing hole 3111 and each connecting hole 61. The fixing member 7 is threadedly connected to the fixing hole 3111, that is, a detachable fixed connection structure is realized between the linkage rod 321 and the buffer belt 31 in a threaded connection manner, which is convenient for later maintenance personnel to repair and replace the buffer belt 31 that has produced a certain amount of wear, thereby reducing the later maintenance cost of this embodiment, and the fixing member 7 in this embodiment is preferably a common threaded fastener on the market such as a bolt, so that a replacement can be quickly found when the fixing member 7 is lost or damaged.

[0034] Since a car will exert a certain horizontal impact force on this embodiment when passing through it, in order to prevent this force from causing deformation of the connecting plate 6 or the linkage rod 321, a plurality of reinforcing ribs 8 are provided between the connecting plate 6 and the linkage rod 321, so that a strong triangular structure is formed between the connecting plate 6, the linkage rod 321 and the reinforcing ribs 8, thereby preventing the connecting plate 6 or the linkage rod 321 from being deformed due to force, and the reinforcing ribs 8 are evenly distributed around the linkage rod 321 in a circle, so that the overall structure of the buffer assembly 32 is more solid.

[0035] like Figure 2 , Figure 4 As shown, the buffer belt 31 in this embodiment includes a plurality of buffer bodies 311. Since various vehicles pass through different positions when passing through this embodiment, the degree of wear of various parts of the buffer belt 31 is also different. The buffer bodies 311 are arranged in sequence along the linear direction, and the buffer bodies 311 are fixedly connected to the ends of the linkage rods 321 away from the buffer cylinder 322 one by one, that is, the buffer belt 31 is divided into a plurality of buffer bodies 311, so that when a part of the buffer belt 31 is ready for replacement, it is only necessary to replace the corresponding buffer body 311, and there is no need to replace the entire buffer belt 31, so that the later maintenance cost of this embodiment is effectively controlled.

[0036] The end of the speed bump body 1 away from the buffer body 311 is an arched structure, so that the speed bump body 1 can remain stable under the action of external forces such as the impact force brought by the running of the vehicle, and has good shock resistance. In addition, the elastic force of the elastic material constituting the speed bump body 1 can fully alleviate the external force, thereby preventing the speed bump body 1 from being damaged and ensuring the stability of the overall structure of this embodiment; the end of the buffer body 311 close to the speed bump body 1 is an arc structure, so that when the external force is transmitted to the buffer body 311 along the speed bump body 1, it will be dispersed by the buffer body 311 with the help of the arc structure, avoiding the external force from being concentrated on a certain point on the buffer body 311, thereby improving the bearing capacity of the buffer body 311, and then preventing the buffer body 311 from being deformed by force, thereby ensuring the stability of the overall structure of this embodiment.

[0037] At the same time, considering that the non-Newtonian fluid 4 itself has a certain viscosity, during the resetting process of the linkage rod 321, part of the non-Newtonian fluid 4 may stick to the linkage rod 321, thereby moving out of the buffer cylinder 322, and eventually causing the non-Newtonian fluid 4 in the buffer cylinder 322 to gradually decrease, and eventually causing the present embodiment to fail to work. Figure 3 As shown, a plurality of sealing rings 5 ​​are provided between the linkage rod 321 and the buffer cylinder 322 in this embodiment, and the non-Newtonian fluid 4 is blocked by the sealing rings 5. The sealing rings 5 ​​are arranged in sequence along a linear direction to fully ensure the blocking effect of the sealing rings 5, thereby ensuring the integrity of this embodiment.

[0038] An auxiliary pressure plate 3211 is provided at the end of the linkage rod 321 away from the buffer belt 31. The auxiliary pressure plate 3211 expands the contact area between the linkage rod 321 and the non-Newtonian fluid 4, thereby reducing the pressure per unit area of ​​the non-Newtonian fluid 4, thereby ensuring that when the vehicle slowly passes through this embodiment, the non-Newtonian fluid 4 will not harden due to the force, thereby ensuring the practicality of this embodiment. The auxiliary pressure plate 3211 is a conical structure, that is, the diameter of the end of the auxiliary pressure plate 3211 close to the buffer belt 31 is smaller than the diameter of the end away from the buffer belt 31, so that when the auxiliary pressure plate 3211 is separated from the non-Newtonian fluid 4 under the action of the elastic member 9, the conical structure can be used to drain water, thereby reducing the resistance of the auxiliary pressure plate 3211 to separate from the non-Newtonian fluid 4 and preventing the non-Newtonian fluid 4 from remaining on the auxiliary pressure plate 3211.

[0039] At the same time, due to the installation groove 2 being provided on the ground, rainwater may seep into the installation groove 2 on rainy days, resulting in water accumulation inside the installation groove 2. To avoid this phenomenon, Figure 2As shown, the mounting groove 2 in this embodiment is provided with a plurality of mounting bosses 21 and a plurality of drainage ports 22, and each buffer cylinder 322 is fixedly connected to each mounting boss 21 in a one-to-one correspondence, that is, the horizontal height of the buffer cylinder 322 is raised by the mounting boss 21, so as to prevent the buffer cylinder 322 from contacting the accumulated water infiltrating into the mounting groove 2; at the same time, the longitudinal section of the mounting boss 21 is an isosceles trapezoidal structure, and the bottom of the buffer cylinder 322 and the upper bottom of the mounting boss 21 overlap each other on the horizontal projection plane, thereby preventing the water infiltrating into the mounting groove 2 from remaining on the mounting boss 21, thereby preventing the outer shell of the buffer cylinder 322 from being corroded and damaged due to long-term immersion in water, and ensuring the service life of the buffer cylinder 322 in this embodiment. And the mounting groove 2 is connected to drainage facilities such as sewers through a plurality of drainage ports 22, so that this embodiment has a drainage function, thereby preventing the accumulation of water in the mounting groove 2.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
