Detailed Implementation

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Figure 1 This is a structural schematic diagram of the walking aid in this utility model. Figure 2 This is a structural schematic diagram of the shock absorption mechanism in this utility model. Figure 3 This is a cross-sectional view of the shock absorption mechanism in this utility model. Figure 4 yes Figure 3 The enlarged view at point A shows that the damping mechanism 1 includes a support member 11, a damping element 12, and a support base 13. The support member 11 has a receiving cavity 110, in which a connecting rod 17 is inserted. The damping element 12 is disposed in the receiving cavity 110 and is located below the connecting rod 17. The support base 13 is provided with a fixing seat 131, which is located below the support member 11. The fixing seat 131 is provided with multiple fixing bosses 1311, with a preset gap between the multiple fixing bosses 1311. The damping element 12 is engaged with the multiple fixing bosses 1311 based on the preset gap. The damping element 12 can be a spring, a rubber spring, a shock absorber, or an air spring. The following description uses a spring as an example of the damping element 12. In this embodiment, the damping element 12 is used to absorb the kinetic energy of the connecting rod 17 and the kinetic energy of the fixed seat 131. When the connecting rod 17 is subjected to force and moves towards the damping element 12, the damping element 12 is compressed by the pressure of the connecting rod 17, thereby converting the kinetic energy of the connecting rod 17 into other potential energy of the damping element 12 to buffer the external force. The fixed seat 131 is provided with eight fixed bosses 1311, which form a circle around the fixed bosses 1311, so that the spring can be locked in the preset gap formed by two adjacent fixed bosses 1311. This avoids the spring being subjected to unbalanced force during use, which could cause the spring to shift. This helps to reduce the risk of additional bending deformation of the spring during use, thereby improving the working stability of the damping mechanism 1.

[0024] In some embodiments, the damping mechanism 1 is further provided with a fixing rod 14, one end of which is fixedly connected to the support member 11, and the other end of which is connected to the support base 13. In this embodiment, the fixing rod 14 is used to connect the support member 11 and the support base 13, thereby enhancing the overall stability of the damping mechanism 1, preventing displacement or deformation during vibration, strengthening the structural strength of the damping mechanism 1, and reducing the probability of damage to the damping mechanism 1.

[0025] In some embodiments, a connector 15 is provided on one end of the fixing rod 14 near the support member 11, and the fixing rod 14 is fixedly connected to the support base 13 based on the connector 15. The connector 15 is used to connect the fixing rod 14 and the support base 13, avoiding direct connection between the fixing rod 14 and the support base 13. This prevents the connecting rod 17 from directly transmitting force to the support base 13 or the support base 13 from directly transmitting force to the connecting rod 17 when subjected to force. This would result in the equipment being subjected to continuous impact and vibration during operation, which would accelerate the wear of components, shorten the service life of the equipment, and cause structural deformation of the equipment, or even breakage or damage to components. This is beneficial for extending the service life of the shock absorption mechanism 1.

[0026] In some embodiments, the connector 15 is rotatably connected to the support base 13. The connector 15 is driven by the fixing rod 14 to rotate around the connection point between the connector 15 and the support base 13. In this embodiment, when the fixing rod 14 is moved by an external force, it causes the connector 15 to rotate around the connection point between the connector 15 and the support base 13. The rotation of the connector 15 at a certain angle helps to distribute the external force on the fixing rod 14 along its rotation direction to the support base 13. Similarly, when the support base 13 is subjected to an external force, it causes the connector 15 to rotate slightly around the connection point between the connector 15 and the support base 13. This helps to distribute a portion of the force on the base along its rotation direction to the fixing rod 14, preventing breakage or damage to the components due to continuous impact and vibration, and extending the service life of the shock absorption mechanism 1.

[0027] In some embodiments, an egg-shaped connecting groove 132 is provided on one end of the support base 13 near the connector 15, and the connector 15 is movably connected to the egg-shaped connecting groove 132 based on a sleeve. The egg-shaped connecting groove 132 is used to limit the rotation angle of the connector 15. When the connector 15 is driven to rotate by the fixing rod 14, the connector 15 drives the sleeve to move along the inner wall of the egg-shaped connecting groove 132. When the sleeve moves to one end of the egg-shaped connecting groove 132, one end of the egg-shaped connecting groove 132 abuts against the sleeve, preventing the sleeve from continuing to move along the inner wall of the egg-shaped connecting groove 132, thereby limiting the rotation angle of the connector 15. This prevents the connector 15 from rotating too much, which could cause the connection between the connector 15 and the support base 13 to loosen or even fall off. This helps to ensure the connection strength between the connector 15 and the support base 13, keeping the connector 15 connected to the support base 13.

[0028] It should be noted that the egg-shaped limiting groove has an upper limit and a lower limit. The upper limit is used to restrict the position of the support base 13, reducing the risk that the support base 13 may detach due to the elastic force of the shock absorber during use. The lower limit is used to fix the shock absorber, giving it a fixed stroke and reducing the risk of it failing due to excessive compression during use.

[0029] In some embodiments, a connecting block 16 is provided at one end of the support member 11 near the fixing rod 14. Multiple reinforcing ribs are provided within the connecting block 16. In this embodiment, eight reinforcing ribs are provided on the connecting block 16, with each pair of reinforcing ribs forming an X-shaped reinforcing rib. That is, four X-shaped reinforcing ribs are provided on the connecting block 16, and the four X-shaped reinforcing ribs are evenly distributed within the connecting block 16. This significantly improves the strength and rigidity of the plastic part or other structural components. By increasing the support points within the structure, the eight reinforcing ribs effectively disperse the stress under external forces, thereby enhancing the overall load-bearing capacity of the structure.

[0030] This utility model also proposes a walking aid 100, which includes a shock-absorbing mechanism 1 and a seat 2 as described above. The shock-absorbing mechanism 1 is located below the seat 2 and is connected to the seat 2. When the walking aid 100 travels on a bumpy road, the shock-absorbing mechanism 1 can reduce the road feel directly transmitted to the seat 2 from the bumpy road surface. The shock-absorbing mechanism 1 absorbs the vibration generated on the bumpy road surface, reducing the discomfort of walking on bumpy roads and improving the user experience. Conversely, when the user sits on the seat 2, the shock-absorbing mechanism 1 cushions the user's weight on the seat 2, reducing the noticeable jerking sensation when the user sits on the seat 2, which is beneficial to improving the user experience.

[0031] In summary, this invention, by setting up a shock-absorbing element within a receiving cavity, avoids the influence of the external environment on the shock-absorbing element, preventing wear and tear and extending its service life. Furthermore, by setting up multiple fixed bosses, this invention restricts the shock-absorbing element to specific positions, reducing the risk of additional bending deformation of the spring components during use, thereby improving the operational stability of the shock-absorbing mechanism.

[0032] Furthermore, the above description of the shock-absorbing mechanism and walking aid provided by the embodiments of this utility model has been detailed. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
