Description

Technical Field

[0001] This utility model relates to the field of traffic engineering, and in particular to a municipal speed bump that can reduce tire damage. Background Technology

[0002] Municipal speed bumps, also known as municipal road speed bumps, are traffic facilities planned, constructed, and maintained by municipal management departments and installed on specific sections of urban roads. Their core function is to forcibly reduce vehicle speed through physical structures, thereby improving road safety, protecting the rights of pedestrians and non-motorized vehicles, and reducing the risk of traffic accidents.

[0003] Municipal speed bumps, which can reduce tire damage, are municipal road traffic safety facilities that minimize physical impact and wear on vehicle tires while fulfilling the core functions of forcing vehicles to slow down and ensuring road safety, through optimized structural design, selection of buffer materials, and precise control of dimensional parameters, based on national standards such as the "Urban Road Engineering Design Code". Essentially, they are a balanced and optimized public infrastructure that balances speed control and tire protection. They are planned, constructed, and maintained by municipal management departments and are mainly used in urban road sections with high traffic volume, such as around schools, residential areas, and pedestrian crossings.

[0004] However, when vehicles drive over traditional municipal speed bumps, the impact force exerted by the vehicles on the speed bumps causes damage to the tires due to the instantaneous high pressure, reducing the tire's lifespan. Therefore, a municipal speed bump that can reduce tire damage is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a municipal speed bump that can reduce tire damage. It aims to improve the problem in the prior art where, when a vehicle drives over a traditional municipal speed bump, the impact force on the speed bump causes damage to the tire due to the instantaneous high pressure, thus reducing the tire's service life.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a municipal speed bump that can reduce tire damage, comprising a connecting base, characterized in that: a vibration damping mechanism is provided on the surface of the connecting base; The vibration damping mechanism includes a telescopic seat, a sliding block elastically connected to the telescopic seat by a spring, a rubber ring sleeved on the surface of the sliding block, a connecting block fixedly connected to the top of the sliding block, a speed bump body slidably connected to the surface of the connecting block, and a drainage mechanism provided on the surface of the speed bump body.

[0007] As a further description of the above technical solution: The drainage mechanism includes a white reflective block, a black reflective block is fixedly connected to the surface of the speed bump body, a drainage groove is opened on the surface of the speed bump body, and a filter plate is fixedly connected inside the drainage groove of the speed bump body.

[0008] As a further description of the above technical solution: One end of the spring is fixedly connected to the inner side wall of the telescopic seat, and the other end of the spring is fixedly connected to the bottom end of the sliding block.

[0009] As a further description of the above technical solution: The inner wall of the telescopic seat has a cavity, and the sliding block is slidably connected in the cavity of the telescopic seat.

[0010] As a further description of the above technical solution: The inner wall of the connecting base has a cavity, and the connecting block is slidably connected in the cavity of the connecting base.

[0011] As a further description of the above technical solution: The lower end of the telescopic seat is fixedly connected to the upper end of the connecting base, and the upper end of the telescopic seat is in contact with the bottom end of the rubber ring.

[0012] As a further description of the above technical solution: The surface of the speed bump body is provided with guide grooves.

[0013] As a further description of the above technical solution: The white reflective block is fixedly connected to the surface of the speed bump body.

[0014] This utility model has the following beneficial effects: 1. In this utility model, a vibration damping mechanism is provided. When a vehicle drives over a speed bump, the sliding block slides in the telescopic seat and compresses the spring. The spring converts the vehicle's impact kinetic energy into elastic potential energy, greatly buffering the impact force, preventing the tire from being damaged by instantaneous high pressure, extending the tire's service life, reducing vehicle bumps, improving driving comfort, protecting the sliding block and telescopic seat, reducing component wear, extending the overall service life of the speed bump, and ensuring long-term stable operation.

[0015] 2. In this utility model, a drainage mechanism is provided. In rainy weather, the drainage grooves on the surface of the speed bump can quickly drain rainwater, preventing water from adhering to the surface of the speed bump and forming a slippery layer. This prevents vehicles from slipping due to reduced friction between the tires and the speed bump, thus reducing driving safety hazards. At the same time, the filter plate in the drainage groove can intercept fallen leaves, gravel and other debris, preventing them from clogging the drainage channel. In addition, the white and black reflective blocks in the drainage mechanism can enhance visual warning under different lighting conditions during the day and night, helping to remind drivers to slow down in advance and further improving traffic safety.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 - Figure 3In one embodiment of this utility model, a vibration damping mechanism 2 is provided on the surface of the connecting base 1. The vibration damping mechanism 2 includes a telescopic seat 21, the inner wall of which has a cavity. A sliding block 23 is slidably connected in the cavity of the telescopic seat 21. The cavity in the inner wall of the telescopic seat 21 serves to limit and guide the sliding block 23, so that the sliding block 23 can only slide along the direction of the telescopic seat 21. The lower end of the telescopic seat 21 is fixedly connected to the upper end of the connecting base 1. The connecting base 1 serves to support and fix the telescopic seat 21. At the same time, the connecting base 1 has threaded grooves around its perimeter. Before installation, the connecting base 1 is fixed. Upon reaching the ground, the upper end of the telescopic seat 21 contacts the lower end of the rubber ring 24. The downward compression of the telescopic seat 21 against the rubber ring 24 reduces downward pressure during vehicle movement, minimizing tire damage and providing initial cushioning. The telescopic seat 21 is elastically connected to a sliding block 23 via a spring 22. One end of the spring 22 is fixedly connected to the inner sidewall of the telescopic seat 21, and the other end is fixedly connected to the bottom end of the sliding block 23. The spring 22 automatically resets the sliding block 23. A rubber ring 24, made of wear-resistant nitrile rubber, is fitted onto the surface of the sliding block 23, and its inner diameter is the same as that of the sliding block 23. The outer diameter is interference-fitted. The top of the sliding block 23 is fixedly connected to the connecting block 25. When the connecting block 25 is pressed down by the car on top, it will simultaneously drive the bottom sliding block 23 to compress the spring 22 and slide down. The inner wall of the connecting base 1 has a cavity. The connecting block 25 is slidably connected in the cavity of the connecting base 1. The function of the cavity of the connecting base 1 is to limit and guide the connecting block 25, so that the connecting block 25 can only slide along the direction of the cavity of the connecting base 1. The surface of the connecting block 25 is slidably connected to the speed bump body 26. When the connecting block 25 slides down, it will simultaneously drive the speed bump body 26 to slide down. The surface of the speed bump body 26 is provided with a drainage mechanism 3.

[0020] Reference Figure 2 - Figure 4 The drainage mechanism 3 includes a white reflective block 31, which is fixedly connected to the surface of the speed bump body 26. The white reflective block 31 is fixedly connected to the preset groove on the surface of the speed bump body 26 by an inlay process. It is made of high refractive index glass microspheres to enhance the nighttime reflective effect. A black reflective block 32 is fixedly connected to the surface of the speed bump body 26. The white reflective block 31 and the black reflective block 32 are arranged alternately to form warning stripes. A drainage groove is opened on the surface of the speed bump body 26. The drainage groove on the surface of the speed bump body 26 is opened along the surface of the speed bump body 26. In case of rain, rainwater can be discharged along the drainage groove on the surface of the speed bump body 26. A guide groove is opened on the surface of the speed bump body 26. The guide groove is connected to the drainage groove to guide the water out. A filter plate 33 is fixedly connected in the drainage groove of the speed bump body 26. The filter plate 33 is used to prevent mud, sand and other debris from entering the drainage groove and causing blockage.

[0021] Working principle: When a vehicle travels over a speed bump, the speed bump body 26 is first subjected to the pressure of the vehicle. Since the speed bump body 26 is fixedly connected to the sliding block 23 through the connecting block 25, and the sliding block 23 is fitted with a rubber ring 24 and elastically connected to the telescopic seat 21 through the spring 22, the pressure is transmitted to the sliding block 23, causing the sliding block 23 to slide downward in the cavity of the telescopic seat 21, compressing the spring 22. During the compression process, the spring 22 converts part of the vehicle's kinetic energy into elastic potential energy, thereby buffering the impact of the vehicle on the speed bump, reducing the impact on the tires, and protecting the tires. The rubber ring 24 can further reduce shock and noise, while protecting the sliding block 23.

[0022] During the process of a vehicle passing over a speed bump, the drainage mechanism 3 on the surface of the speed bump body 26 also plays a role. In rainy weather, rainwater will fall on the speed bump body 26 and then flow to the ground through the drainage channels on its surface. If there is no drainage outlet on one side of the speed bump, rainwater may accumulate and lower the speed bump. If the accumulated water is level with the speed bump body 26, it will result in poor visibility, making it impossible to see the speed bump body 26 and causing delayed deceleration. At the same time, the filter plate 33 in the drainage channel can prevent debris from entering the drainage channel, avoid blockage, ensure smooth drainage, and keep the surface of the speed bump dry, ensuring vehicle driving safety. In addition, the white reflective blocks 31 and black reflective blocks 32 on the surface of the speed bump body 26 can serve as a warning both day and night, reminding drivers to slow down, further improving traffic safety performance.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
