Description

Technical Field

[0001] The utility model relates to the technical field of spring buffer pads, in particular to a spring buffer pad. Background Art

[0002] A scooter is a vehicle or toy with a gliding function, typically consisting of two or three wheels, designed for personal transportation or recreation. Scooters come in various types, including electric scooters, children's scooters, and three-wheeled scooters, each with its own unique characteristics and usage scenarios. During scooter installation, spring cushions are typically used. These cushions operate based on the principles of energy conversion and elastic deformation. When an object in motion is impacted or vibrated, it acquires a certain amount of kinetic energy. The spring cushion converts this kinetic energy into the elastic potential energy required for elastic deformation. When the kinetic energy of the moving object decreases to a certain level, the cushion begins to release this stored elastic potential energy and converts it into deformation energy, thereby completely dissipating the object's kinetic energy and achieving the purpose of shock absorption and energy absorption. The stiffness and shape of the spring cushion affect the torque attenuation effect, which refers to the ability of the spring cushion to absorb some torque and convert it into elastic deformation energy, thereby reducing vibration and shock.

[0003] Based on the above, the inventors have found the following problems: existing spring buffer pads are generally cylindrical in shape and have a relatively high rigidity, which results in a relatively small elastic deformation of the spring buffer pad, thereby reducing the shock absorption performance of the spring buffer pad.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a spring buffer pad is provided to achieve the purpose of having more practical value. Utility Model Content

[0005] The purpose of the present invention is to provide a spring buffer pad to solve the problems raised in the above background technology.

[0006] In view of the above problems, the technical solution proposed by the present invention is:

[0007] A spring buffer pad includes a main body, the main body including a buffer pad, a groove, a through hole, a snap-fit ​​strip and an anti-slip seat, the buffer pad is truncated cone-shaped, and the top surface diameter of the buffer pad is smaller than the bottom surface diameter, the outside of the buffer pad is provided with a groove near the bottom end, the inside center of the buffer pad is provided with a through hole, the inner wall of the through hole is provided with three snap-fit ​​strips, and the bottom surface of the buffer pad is provided with four anti-slip seats.

[0008] Furthermore, the inner angle of the groove is less than ninety degrees.

[0009] The beneficial effect of adopting the above-mentioned further scheme is that by setting a groove, and the angle in the groove is less than ninety degrees, the cushioning pad with an angle less than ninety degrees has smaller stiffness than the cushioning pad with an angle of ninety degrees. When the cushioning pad with an angle less than ninety degrees and the cushioning pad with an angle of ninety degrees are under the same stress level, the cushioning pad with an angle less than ninety degrees can provide a softer cushioning effect. At the same time, the setting of the groove can make it easier for the cushioning pad to absorb the energy when it is subjected to impact or vibration, making the cushioning pad more durable.

[0010] Furthermore, the outer walls of the three engaging strips are respectively connected to the inner wall of the through hole, and the three engaging strips are distributed in an equidistant ring shape, and the lengths of the three engaging strips are consistent with the height of the through hole.

[0011] The beneficial effect of adopting the above-mentioned further scheme is that by setting a through hole, it is convenient to insert the threaded sleeve into the through hole, and by setting three snapping strips on the inner wall of the through hole, and the length of the snapping strips is consistent with the height of the through hole, the outer wall of the threaded sleeve is provided with three snapping grooves adapted to the snapping strips, and the height of the snapping grooves is consistent with the height of the snapping strips. After the three snapping grooves are aligned with the three snapping strips respectively, the threaded sleeve with internal threads is slowly inserted into the inside of the through hole, which facilitates the subsequent connection of the threaded sleeve, buffer pad and bolt.

[0012] Furthermore, the top surfaces of the four anti-slip seats are respectively connected to the bottom surface of the buffer pad, and the four anti-slip seats are distributed in an equidistant ring shape, and the four anti-slip seats are hemispherical.

[0013] The beneficial effect of adopting the above-mentioned further scheme is that by arranging four anti-slip seats on the bottom surface of the buffer pad, it can avoid the friction between the bottom surface of the buffer pad and the surface where it is fixed, causing abnormal noise when the bolt is loosened. At the same time, the arrangement of the four anti-slip seats can increase the friction between the bottom surface of the buffer pad and the surface where it is fixed.

[0014] Furthermore, the buffer pad, three snap-fitting strips and four anti-slip seats are all made of silicone.

[0015] The beneficial effect of adopting the above-mentioned further scheme is that by setting the buffer pad, three snap strips and four anti-slip seats to silicone material, the silicone material has the characteristics of high elasticity, weather resistance, durability and durability, which improves the buffer pad, three snap strips and four anti-slip seats. The service life is longer and they are not easily aged or damaged when used for a long time under different climatic conditions. At the same time, the buffer pad, three snap strips and four anti-slip seats are formed in one piece.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the spring buffer pad, by setting the buffer pad as a whole into a truncated cone shape, and the diameter of the top surface of the buffer pad is smaller than the diameter of the bottom surface, the bottom end of the buffer pad is wider and the upper end is narrower, which plays a positioning role and enables the buffer pad to more effectively disperse and absorb energy when it is impacted. By setting the groove, the telescopic length can be increased, so that the buffer pad can more easily absorb the energy when it is impacted or vibrated. By setting three locking strips on the inner wall of the through hole, and the length of the locking strip is consistent with the height of the through hole, the outer wall of the threaded sleeve is provided with three locking grooves adapted to the locking strip, and the height of the locking groove is consistent with the height of the locking strip. After the three locking grooves are aligned with the three locking strips respectively, the threaded sleeve with internal threads is slowly inserted into the inside of the through hole, which is convenient for the subsequent connection of the threaded sleeve, buffer pad and bolt. By setting four anti-slip seats, the friction between the bottom surface of the buffer pad and the surface where it is fixed can be increased, avoiding the mutual friction between the bottom surface of the buffer pad and the surface where it is fixed, causing abnormal noise.
