DETAILED DESCRIPTION

[0035] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related utility model, and not to limit the utility model. In addition, it should be noted that only parts related to the utility model are shown in the drawings for ease of description.

[0036] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0037] Embodiment 1

[0038] Please refer to Figures 1-12 The present application provides a damping structure applied to a gas pump device, comprising:

[0039] The damping elastic body 3 is provided with a multistage damping structure on the outer surface, and the multistage damping structure is used to gradually reduce the damping effect.

[0040] Specifically, the damping elastic body 3 is a damping rubber ring, which has good elasticity, wear resistance and damping performance, can effectively absorb and buffer impact force, and can maintain performance for a long time and reduce replacement frequency.

[0041] Working principle: when in use, the damping elastic body 3 is arranged between the gas pump body 1 and the shell 2, and when the gas pump body 1 vibrates during use, the multistage damping structure gradually abuts against the shell 2 to gradually reduce the damping effect, reduce the vibration and noise transmitted during use of the gas pump device, and thus improve the comfort of the occupant when riding.

[0042] In some embodiments, the multistage damping structure comprises a plurality of buffer units alternately arranged around the outer surface of the damping elastic body 3; the buffer unit has at least one buffer, wherein the heights of adjacent two buffer units are different.

[0043] Specifically, the multi-stage damping structure includes multiple buffer units arranged alternately around the outer surface of the damping elastomer 3; the buffer unit has at least one buffer piece, wherein the height of the adjacent two buffer units is different; in use, the damping elastomer 3 is arranged between the air pump body 1 and the shell 2, when the air pump body 1 generates vibration during use, the first-stage buffer unit first contacts the shell 2, and the first-stage buffer unit has the highest height, so that the contact with the shell 2 is light and slow, thereby playing a buffering role; then, the buffer units are contacted with the shell 2 in stages, and the damping effect is enhanced in stages, thereby playing a role of anti-collision and damping;

[0044] In some embodiments, the buffer piece is a hollow triangular prism structure or a cylindrical structure.

[0045] In some embodiments, as shown in Figures 1-3 , the buffer piece is a hollow triangular prism structure, which can provide more uniform distribution and enhance the damping effect when subjected to impact or vibration, thereby reducing damage to the air pump body 1.

[0046] In some embodiments, as shown in Figures 4-6 , the buffer piece is a cylindrical structure, which can effectively absorb and dissipate vibration energy when subjected to impact, thereby enhancing the damping effect and protecting the air pump body 1.

[0047] In some embodiments, the buffer piece has multiple buffer portions 12 arranged along the extension direction of the buffer piece, and the diameters of the multiple buffer portions 12 gradually decrease away from the damping elastomer 3.

[0048] Specifically, as shown in Figure 12 , the buffer piece has multiple buffer portions 12 arranged along the extension direction of the buffer piece, and the diameters of the multiple buffer portions 12 gradually decrease away from the damping elastomer 3; with the above design, when the impact force acts on the buffer piece, the energy is first absorbed by the buffer portion 12 with the smaller diameter; as the impact force is transmitted, the subsequent buffer portions 12 with gradually increasing diameters further disperse and absorb the remaining energy; this step-by-step dispersion method makes the impact force continuously weakened during transmission; at the same time, since the impact force is absorbed in stages, the impact load borne by each buffer portion 12 is relatively small, thereby reducing the risk of damage caused by excessive single impact and improving the overall durability of the buffer piece.

[0049] In some embodiments, the multi-stage damping structure is a two-stage damping structure, and the two-stage damping structure includes a first-stage buffer unit and a second-stage buffer unit; the height of the first-stage buffer unit is higher than the height of the second-stage buffer unit.

[0050] Specifically, the multi-stage damping structure is a two-stage damping structure, and the two-stage damping structure includes a first-stage buffer unit and a second-stage buffer unit;

[0051] In some embodiments, such as Figures 1-3 As shown, both the primary and secondary buffer units are hollow triangular prism structures. In this embodiment, the primary buffer unit has one primary buffer element 7, and the secondary buffer unit has one secondary buffer element 8. Multiple primary buffer elements 7 and multiple secondary buffer elements 8 are arranged alternately around the shock-absorbing elastic body 3 in a circumferential manner to achieve uniform shock absorption. In this embodiment, the primary buffer element 7 has a first vertex, a second vertex, and a third vertex. The second and third vertices are located on the shock-absorbing elastic body 3, and the first vertex is located away from the shock-absorbing elastic body 3. The secondary buffer element 8 has a fourth vertex, a fifth vertex, and a sixth vertex. The fifth vertex and... The sixth vertex is set on the shock-absorbing elastomer 3, and the fourth vertex is set away from the shock-absorbing elastomer 3; the distance between the first vertex and the shock-absorbing elastomer 3 is greater than the distance between the fourth vertex and the shock-absorbing elastomer 3, and the distance between the second vertex and the third vertex is greater than the distance between the fifth vertex and the sixth vertex; at this time, when the air pump body 1 vibrates during use, it first comes into contact with the housing 2 from the first-level buffer 7. The contact between the first-level buffer 7 and the housing 2 is relatively light and slow, which plays a buffering role; then the second-level buffer 8 comes into contact with the housing 2, further enhancing the buffering effect on the air pump body 1, and finally playing a role in anti-collision and shock absorption;

[0052] In some embodiments, such as Figures 4-6 As shown, both the primary and secondary buffer units are cylindrical structures; the primary and secondary buffer units are arranged alternately around the shock-absorbing elastomer 3 in a circumferential direction; in this embodiment, the primary buffer unit has two primary buffer elements 7, which are arranged along the first direction, and the secondary buffer unit has three secondary buffer elements 8, which are arranged along the first direction; the first direction is parallel to the air pump body 11, and in this embodiment, the first direction is the vertical direction;

[0053] Meanwhile, since both the primary buffer 7 and the secondary buffer 8 are cylindrical structures, the height of the primary buffer 7 is higher than that of the secondary buffer 8, and the diameter of the primary buffer 7 is smaller than that of the secondary buffer 8. When the air pump body 1 vibrates during use, it first comes into contact with the housing 2 from the primary buffer 7. The contact between the primary buffer 7 and the housing 2 is relatively light and gentle, thus playing a buffering role. Subsequently, the secondary buffer 8 comes into contact with the housing 2, further enhancing the buffering effect on the air pump body 1, and ultimately playing a role in anti-collision and shock absorption.

[0054] In some embodiments, such as Figure 7As shown, the first-level buffer unit and the second-level buffer unit are both in cylindrical structure; the first-level buffer unit has two first-level buffer pieces 7 arranged along the first direction, and the second-level buffer unit has two second-level buffer pieces 8 arranged along the first direction.

[0055] In some embodiments, the multi-level damping structure is a three-level damping structure, which includes a first-level buffer unit, a second-level buffer unit and a third-level buffer unit; the first-level buffer unit includes at least one first-level buffer piece 7, the second-level buffer unit includes at least one second-level buffer piece 8, and the third-level buffer unit includes at least one third-level buffer piece 9; the heights of the first-level buffer piece 7, the second-level buffer piece 8 and the third-level buffer piece 9 decrease in turn.

[0056] Specifically, as shown in the figure, Figures 9-11 As shown, the multi-level damping structure is a three-level damping structure, which includes a first-level buffer unit, a second-level buffer unit and a third-level buffer unit; in this embodiment, the first-level buffer unit has two first-level buffer pieces 7 arranged along the first direction, the second-level buffer unit has two second-level buffer pieces 8 arranged along the first direction, and the third-level buffer unit has two third-level buffer pieces 9 arranged along the first direction; at the same time, since the first-level buffer piece 7, the second-level buffer piece 8 and the third-level buffer piece 9 are all in cylindrical structure, the heights of the first-level buffer piece 7, the second-level buffer piece 8 and the third-level buffer piece 9 decrease in turn, and the diameters of the first-level buffer piece 7, the second-level buffer piece 8 and the third-level buffer piece 9 increase in turn; when the air pump body 1 vibrates during use, the first-level buffer piece 7 first contacts the shell 2, the first-level buffer piece 7 contacts the shell 2 gently and slowly, thereby playing a buffering role; then the second-level buffer piece 8 and the third-level buffer piece 9 contact the shell 2 in turn, thereby gradually enhancing the buffering effect on the air pump body 1, and finally playing a role of anti-collision and damping.

[0057] At the same time, in some embodiments, as shown in the figure, Figure 10 As shown, the third-level buffer unit is arranged between the first-level buffer unit and the second-level buffer unit, that is, the first-level buffer unit and the second-level buffer unit are arranged alternately, and the third-level buffer unit is arranged between each first-level buffer unit and second-level buffer unit, so as to improve the buffering and damping effect;

[0058] In this embodiment, there are 7 first-level buffer units, 7 second-level buffer units and 14 third-level buffer units.

[0059] In some embodiments, the inner surface of the damping elastic body 3 is circumferentially provided with a plurality of heat dissipation support units, and each heat dissipation support unit has at least one heat dissipation support piece 11, which is used to leave a heat dissipation gap.

[0060] In some embodiments, the shock-absorbing elastic body 3 is usually sleeved on the outer surface of the air pump body 1 to absorb the shock of the air pump body 1, but such arrangement may weaken the heat dissipation effect of the air pump body 1; therefore, the inner surface of the shock-absorbing elastic body 3 is circumferentially provided with a plurality of heat dissipation support units; in the present embodiment, the heat dissipation support units include two heat dissipation support pieces 11 arranged along the first direction; the heat dissipation support pieces 11 are located between the air pump body 1 and the shock-absorbing elastic body 3, so that a heat dissipation gap is left between the air pump body 1 and the shock-absorbing elastic body 3, thereby ensuring the heat dissipation effect of the air pump body 1 and avoiding damage to the air pump body 1.
