[0023] The embodiments of the present application provide a shock-absorbing sports floor, thereby solving the technical problems of high material cost, limited lifespan and limited use cycle of shock-absorbing floors in the prior art.
[0024] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:
[0025] A buffer component is also provided on the side of the surface layer 1 facing the elastic base layer 3, and the buffer component has a rigid part 5 and an elastic part 6. The buffer component and the elastic base layer 3, the impact-resistant layer 2 and the surface layer 1 together constitute a linear shock-absorbing system. When a human body steps on the surface layer 1, the impact-resistant layer 2 in the middle position can be used to buffer the vibration, and the buffer component can also be used to buffer the vibration. Therefore, compared with the floor of the prior art, the shock-absorbing sports floor of the present application produces a smaller response amplitude under the same vibration excitation, so that it has higher shock-absorbing performance, avoids the reaction force impact of the rigid floor on the human body during exercise, is beneficial to reduce the burden on the body, and ensures that the exercise process is light and safe.
[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0027] like Figure 1 As shown, one or more embodiments of the present application provide a shock-absorbing sports floor, including an elastic base layer 3, on which an impact-resistant layer 2 and a surface layer 1 are arranged in sequence; wherein a buffer component is also provided on the side of the surface layer 1 facing the elastic base layer 3, and the buffer component includes an elastic member 6 and a rigid member 5 fixedly connected to one end of the elastic member 6, the other end of the elastic member 6 abuts against the elastic base layer 3 or the impact-resistant layer 2, and the rigid member 5 abuts against the surface layer 1.
[0028] From the above description, it can be seen that the shock-absorbing sports floor provided by the present application is provided with a buffer component on the side of the surface layer 1 facing the elastic base layer 3, and the buffer component has a rigid part 5 and an elastic part 6. The buffer component and the above-mentioned elastic base layer 3, impact-resistant layer 2 and surface layer 1 together constitute a linear shock-absorbing system. When a human body steps on the surface layer 1, the impact-resistant layer 2 in the middle position can be used to buffer the vibration, and the buffer component can also be used to buffer the vibration. Therefore, compared with the floors of the prior art, the shock-absorbing sports floor of the present application produces a smaller response amplitude under the same vibration excitation, thereby having a higher shock-absorbing performance, avoiding the reaction force impact of the rigid floor on the human body during exercise, which is beneficial to reducing the burden on the body and ensuring that the exercise process is light and safe.
[0029] In some embodiments, the elastic base layer 3 and the impact-resistant layer 2 are made of polypropylene material. Polypropylene (PP for short) is a widely used plastic material with good thermal stability and impact resistance, and can therefore be used on sports floors. As an alternative embodiment, the elastic base layer 3 and the impact-resistant layer 2 can also be made of materials commonly used in sports floors in other related technologies, such as rubber materials or PVC materials.
[0030] like Figure 1 As shown, in some embodiments, the elastic base layer 3 is provided with a mounting groove 8 for avoiding the buffer component, and one end of the elastic member 6 facing away from the elastic member 6 is fixed to the mounting groove 8 .
[0031] Here, by Figure 1 It can also be seen that the elastic member 6 in the buffer assembly is in contact with the surface layer 1, and the end of the elastic member 6 facing away from the rigid member 5 is directly in contact with the elastic base layer 3, and the buffer assembly has no contact and connection with the impact-resistant layer 2. Therefore, the impact-resistant layer 2 and the buffer assembly together constitute a two-degree-of-freedom linear shock absorption system. When a human body steps on the surface layer 1, the displacement of the rigid member 5 is x(t), and the impact-resistant layer 2 is also compressed by the surface layer 1, and the deformation displacement relative to the elastic base layer 3 is y(t). Under the buffering of this two-degree-of-freedom linear system, the response amplitude of the entire sports floor will be reduced to a certain extent, that is, under the action of the same force, y(t) will be further reduced, thereby increasing the bearing capacity threshold of the entire sports floor and enhancing the shock absorption effect.
[0032] In some embodiments, a damping member 7 is further connected between the rigid member 5 and the mounting slot 8, and the damping coefficient of the damping member 7 is negatively correlated with the stiffness coefficient of the elastic member 6. Here, exemplarily, the elastic member 6 is a spring, and the spring and the damping member 7 together constitute the buffer assembly. The spring is used to store and release energy. When the buffer assembly is subjected to external force (such as human body's stepping pressure), the spring will compress and absorb part of the energy. Subsequently, the spring releases this energy to return the system to a balanced state; the damping member 7 is used to consume the energy of the buffer assembly, especially the vibration energy. The damping member 7 reduces the vibration amplitude and speed of the buffer assembly through resistance (friction or other forms of energy dissipation), thereby preventing the buffer assembly from excessive vibration and possible resonance, and ensuring the stability of the buffer assembly.
[0033] In the above embodiment, the damping member 7 can adopt a mature damper in the relevant technology, and the damping coefficient of the damping member 7 is adjustable. The larger the spring stiffness coefficient, the harder the spring, and the smaller the damping coefficient of the damping member 7. The smaller the spring stiffness coefficient, the softer the spring, and the larger the damping coefficient of the damping member 7. Of course, the selection of the damping member 7 and the spring in the embodiment of the present application is only an exemplary description. In the entire two-degree-of-freedom linear system, the selection and synergy of vibration characteristic parameters such as the mass of the selected rigid member 5, the spring stiffness coefficient, the damping of the damping member 7, and the damping ratio of the damping member 7 and the impact-resistant layer 2 will have an impact on the actual effect of the entire system. Therefore, it needs to be flexibly determined according to the actual scenario.
[0034] In some embodiments, the impact-resistant layer 2 is disposed on both sides of the elastic base layer 3, and the installation groove 8 is located in the middle area of the elastic base layer. Through this arrangement, the human body can step on the surface layer 1 area corresponding to the buffer component to a greater extent during running, which is conducive to utilizing the buffer component for cushioning and shock absorption.
[0035] In some embodiments, Figure 1 As shown, the surface layer 1 includes a piezoelectric material layer, the power output end of the piezoelectric material layer is connected to the lighting component 4, and the piezoelectric material layer is configured to generate power under pressure and supply power to the lighting component 4. Here, the piezoelectric material layer is mixed with piezoelectric material and wear-resistant and anti-skid material. For example, the piezoelectric material can be selected from piezoelectric ceramic materials such as lead zirconate bismuth titanate or strontium titanium tungstate, and the wear-resistant and anti-skid material can be selected from corundum material.
[0036] In the above embodiment, the piezoelectric material layer is divided into multiple areas along the extension path of the floor, and the piezoelectric material layer in each area supplies power to the lighting assembly 4 corresponding to the area. It should be noted that the piezoelectric material itself can produce a charge separation effect, but the electric energy it generates is very weak. Therefore, the weak electric energy generated by the piezoelectric material can be converted into electric energy sufficient to drive the load using the relevant technology. For example, a piezoelectric energy storage device or a piezoelectric generator is used to convert the weak electric energy of the piezoelectric material into higher power electric energy. The technical means can refer to the relevant technology, and this application will not repeat it.
[0037] As an alternative embodiment, the surface layer 1 includes a solar conductive layer, the power output end of the solar conductive layer is connected to the lighting component 4, and the solar conductive layer is configured to generate power after receiving solar energy and supply power to the lighting component 4. Here, illustratively, the solar conductive layer can be made of amorphous silicon or polycrystalline silicon and other materials, as long as it can convert solar energy into power. When the solar conductive layer is used to generate electricity, an energy storage device in the related technology can be set up to temporarily store the power of the solar conductive layer, and release the power at night for lighting of the light bulb.
[0038] Furthermore, the lighting assembly 4 has at least two groups arranged on both sides of the buffer assembly, and each group of the lighting assembly 4 includes a plurality of light bulbs, and the plurality of light bulbs are arranged at intervals along the length direction of the floor. By using the piezoelectric material layer and the solar conductive layer to power the light bulbs, a weak lighting effect is provided for people running at night, which not only plays a guiding and leading role, but also can prevent people from stepping on it in the dark, eliminating safety hazards.
[0039] In some embodiments, the elastic base layer 3 and the impact-resistant layer 2 are integrally injection-molded; or, the elastic base layer 3 and the impact-resistant layer 2 are bonded and connected. This embodiment does not make an absolute limitation to this.
[0040] It should be understood that although the terms "first", "second", etc. may be used herein to describe various units, these units should not be limited by these terms. These terms are used only to distinguish one unit from another. For example, a first unit may be referred to as a second unit, and similarly, a second unit may be referred to as a first unit without departing from the scope of the exemplary embodiments.
[0041] The directional terms such as outer, middle, inner, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to different positions and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.
[0042] The above is only a preferred embodiment of the present application, and is not any formal or substantial limitation to the present application. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the method of the present application, and these improvements and supplements should also be regarded as the protection scope of the present utility model. Any technician familiar with this profession can make some changes, modifications and evolutions of the technical content disclosed above without departing from the spirit and scope of the present application, which are equivalent embodiments of the present application; at the same time, any changes, modifications and evolutions of any equivalent changes made to the above embodiments based on the substantial technology of the present application are still within the scope of the technical solution of the present application.
