DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only for explaining the present utility model and should not be construed as limiting the present utility model.

[0028] The following refers toFigures 1-6 Describing the air spring shock absorber according to an embodiment of the present invention, the intermediate skeleton 41 of the sealing structure 4 presses against the spring seat 3, and the outer elastic sealing portion 43 of the sealing structure 4 cooperates with the piston 2. By the pressing of the piston 2, the outer elastic sealing portion 43 is gradually deformed to play a sealing role. The inner elastic sealing portion 42 of the sealing structure 4 cooperates with the oil storage cylinder 1. By the pressing of the oil storage cylinder 1, the inner elastic sealing portion 42 is gradually deformed to play a sealing role, and the shape of the intermediate skeleton 41 remains unchanged, making the pressing deformation controllable. That is to say, the sealing structure 4 avoids the problem of air leakage existing in the prior art due to the insufficient pressing of the sealing structure 4 or the uncontrollable pressing deformation.

[0029] As Figures 1-6 Describing the air spring shock absorber according to an embodiment of the present invention, including: a piston 2, an oil storage cylinder 1, and a sealing structure 4.

[0030] Wherein, the piston 2 is sleeved outside the oil storage cylinder 1 and one end is connected to the oil storage cylinder 1. A spring seat 3 is provided outside the oil storage cylinder 1, and the other end of the piston 2 presses against the spring seat 3; the sealing structure 4 is annular and includes an intermediate skeleton 41, an inner elastic sealing portion 42, and an outer elastic sealing portion 43. The inner elastic sealing portion 42 is connected to one side of the intermediate skeleton 41 close to the center of the circle of the annulus, and the outer elastic sealing portion 43 is connected to the other side of the intermediate skeleton 41 far from the center of the circle of the annulus. The inner wall of the piston 2 presses against the outer elastic sealing portion 43, the inner elastic sealing portion 42 presses against the outer wall of the oil storage cylinder 1, and the intermediate skeleton 41 presses against the spring seat 3.

[0031] In practice, the piston 2 is sleeved outside the oil storage cylinder 1, and both ends of the piston 2 are relatively fixed to the oil storage cylinder 1. One end of the piston 2 is fixed to one end of the oil storage cylinder 1, and the other end of the piston 2 and the oil storage cylinder 1 are hermetically pressed through the sealing structure 4. A middle rod body 5 is movably connected to the middle of the oil storage cylinder 1, and a protective sleeve is provided outside the piston 2. The lower part of the protective sleeve is a threaded part, and an airbag 6 is provided inside the protective sleeve. The airbag 6 is inflated and deformed, so that the middle rod body 5 moves upward synchronously relative to the oil storage cylinder 1. At the same time, the threaded part at the lower part of the protective sleeve can be slightly stretched to realize the height adjustment of the shock absorber to adapt to different road sections and improve the comfort of vehicle driving.

[0032] In the embodiment of the present invention, mainly the other end of the piston 2 and the oil storage cylinder 1 are hermetically pressed through the sealing structure 4 to prevent air leakage between the piston 2 and the oil storage cylinder 1, which may cause pressure changes and affect the height adjustment of the shock absorber. Specifically, first, the spring seat 3 is welded to the outer periphery of the oil storage cylinder 1. The spring seat 3 is mainly used to support the piston 2, that is, to support the air spring, and fixes the piston 2 in a suitable position, playing a limiting role; then the sealing structure 4 is sleeved on the oil storage cylinder 1 and presses against the spring seat 3, and finally the piston 2 is connected to the oil storage cylinder 1, so that the piston 2 presses against the sealing structure 4.

[0033] Furthermore, the outer elastic sealing portion 43 of the sealing structure 4 cooperates with the inner wall of the piston 2. The outer elastic sealing portion 43 is deformed by the pressing of the piston 2 to play a sealing role. At the same time, the inner elastic sealing portion 42 of the sealing structure 4 cooperates with the oil storage cylinder 1. The inner elastic sealing portion 42 is deformed by the pressing of the oil storage cylinder 1 to play a sealing role. And the middle part of the sealing structure 4 adopts the middle framework 41, that is, while being squeezed and deformed on both sides, the middle part of the sealing structure 4 can still play a supporting role, and at the same time, it also prevents the excessive squeezing deformation and large deformation. Thus, after the sealing structure 4 is squeezed, the gap between the oil storage cylinder 1 and the piston 2 is effectively filled. That is to say, the sealing structure 4 avoids the problem of air leakage existing in the prior art due to the improper press-fitting or uncontrollable press-fitting deformation of the sealing structure 4.

[0034] In some embodiments, the thickness of the inner elastic sealing portion 42 near the spring seat 3 is less than the thickness away from the spring seat 3, so that the inner wall of the inner elastic sealing portion 42 is the first inclined surface 422.

[0035] In practice, the inner elastic sealing portion 42 extends along the height direction of the middle framework 41, and the height of the inner elastic sealing portion 42 is approximately equal to the height of the middle framework 41. The design that the inner wall of the inner elastic sealing portion 42 is the first inclined surface 422 can make the extrusion degree between the upper end of the inner elastic sealing portion 42 and the oil storage cylinder 1 greater than the extrusion degree between the lower end and the oil storage cylinder 1, and can realize the gradual deformation of the inner elastic sealing portion 42, so that the upper end of the inner elastic sealing portion 42 can better fill and seal between the oil storage cylinder 1 and the middle framework 41. And the design of the first inclined surface 422 provides an extrusion space for the deformation of the inner elastic sealing portion 42 when the inner elastic sealing portion 42 is extruded.

[0036] In some embodiments, the included angle between the first inclined surface 422 and the oil storage cylinder 1 or the piston 2 in the radial direction is a, and satisfies: 70°≤a≤85°.

[0037] As Figure 4 shown, by limiting the included angle between the first inclined surface 422 and the oil storage cylinder 1 or the piston 2 in the radial direction, a better gradual pressing effect can be formed from top to bottom for the inner elastic sealing portion 42, which can not only provide an extrusion space for the extrusion of the inner elastic sealing portion 42, but also enable the inner elastic sealing portion 42 to effectively seal the gap between the middle framework 41 and the oil storage cylinder 1. In practice, a is 79°, and of course a can also be 75°, 80°, etc.

[0038] In addition, it should be noted that the inner elastic sealing portion 42 and the outer elastic sealing portion 43 are respectively connected to the intermediate framework 41 as a whole. In this way, when installing the sealing structure 4, when the piston 2 presses against the spring seat 3, the piston 2 can directly press against the outer elastic sealing portion 43, and the inner elastic sealing portion 42 can directly press against the oil storage cylinder 1, which can solve the problem of complex installation of the inner elastic sealing portion 42 and the outer elastic sealing portion 43 installed separately.

[0039] In some embodiments, the inner elastic sealing portion 42 includes a top surface 421, the top surface 421 is inclined, and the side of the top surface 421 close to the intermediate framework 41 is higher than the side far from the intermediate framework 41.

[0040] In practice, since the top surface 421 of the inner elastic sealing portion 42 is inclined, when the inner elastic sealing portion 42 is squeezed, the inner elastic sealing portion 42 can be made to face the oil storage cylinder 1 as much as possible and be in close contact with the outer wall surface of the oil storage cylinder 1, reducing the risk of gaps appearing with the outer wall surface of the oil storage cylinder 1. At the same time, after the inner elastic sealing portion 42 is squeezed, the inner elastic sealing portion 42 can have space for upward deformation when being squeezed.

[0041] That is to say, Figure 4 the inclined setting of the top surface 421 and the inclined setting of the first inclined surface 422 can enable the inner elastic sealing portion 42 to be in sealed contact with the outer wall of the oil storage cylinder 1 when being squeezed. At the same time, it can also save the material for setting the inner elastic sealing portion 42. And in combination with the setting of the intermediate framework 41, it can prevent the inner elastic sealing portion 42 from having a large degree of deformation, and at the same time have a certain space for squeezing deformation.

[0042] In some embodiments, the thickness of the outer elastic sealing portion 43 near the spring seat 3 is greater than the thickness far from the spring seat 3.

[0043] In practice, when the sealing structure 4 is sleeved on the oil storage cylinder 1 and presses against the spring seat 3, the piston 2 is installed in the oil storage cylinder 1, and the piston 2 presses against the outer elastic sealing portion 43. As a result, the degree of squeezing between the piston 2 and the outer elastic sealing portion 43 at the position close to the spring seat 3 is higher, that is, the degree of squeezing between the end of the outer elastic sealing portion 43 close to the spring seat 3 and the piston 2 is higher, while the degree of squeezing between the end of the inner elastic sealing portion 42 far from the spring seat 3 and the oil storage cylinder 1 is higher. Thus, when the inner elastic sealing portion 42 and the outer elastic sealing portion 43 are squeezed between the oil storage cylinder 1 and the piston 2, the force is balanced, preventing the sealing structure 4 from having a large deformation.

[0044] Refer to Figure 5As shown, when the piston 2 presses against the outer elastic sealing part 43, the force applied to the lower end of the outer elastic sealing part 43 is greater than the force applied to the upper end. When the oil storage cylinder 1 presses against the inner elastic sealing part 42, the force applied to the upper end of the inner elastic sealing part 42 is greater than the force applied to the lower end. That is to say, the outer elastic sealing part 43 and the inner elastic sealing part 42 can maintain a balanced force under the pressing action of the oil storage cylinder 1 and the piston 2, so that the deformation of the inner elastic sealing part 42 and the outer elastic sealing part 43 is within a controllable range.

[0045] In some embodiments, the outer elastic sealing part 43 includes a bottom surface 431, the bottom surface 431 is inclined, and the distance between the bottom surface 431 and the spring seat 3 gradually increases from the side close to the middle skeleton 41 to the side far from the middle skeleton 41.

[0046] That is to say, the bottom surface 431 of the outer elastic sealing part 43 is an inclined surface, which can also provide a deformation space when the outer elastic sealing part 43 is pressed. And a sharp angle 432 is formed between the bottom surface 431 and the outer side surface of the outer elastic sealing part 43. By starting to press the piston 2 against the sharp angle 432, the outer elastic sealing part 43 can be deformed appropriately in both the up and down directions of the sharp angle 432. And after the piston 2 deforms the outer elastic sealing part 43 by extrusion, the deformed outer elastic sealing part 43 has a large contact area with the piston 2, improving the sealing performance.

[0047] In some embodiments, the outer elastic sealing part 43 and the inner elastic sealing part 42 are centrosymmetric about the center of the middle skeleton 41.

[0048] In practice, by making the outer elastic sealing part 43 and the inner elastic sealing part 42 centrosymmetric about the center of the middle skeleton 41, the layout of the entire sealing structure 4 can be made reasonable, so that the outer elastic sealing part 43 and the inner elastic sealing part 42 occupy the same space on both sides of the middle skeleton 41, and the force is evenly distributed during extrusion, so that the sealing structure 4 will not have a large offset after extrusion.

[0049] For example, the outer side surface of the outer elastic sealing part 43 and the first inclined surface 422 in the embodiment of the present invention are symmetric surfaces. The included angle between the outer side surface of the outer elastic sealing part 43 and the oil storage cylinder 1 or the piston 2 in the radial direction is b, and the angle b is the same as the above-mentioned angle a, so that the extrusion spaces left by the outer elastic sealing part 43 and the inner elastic sealing part 42 when being pressed are the same. That is to say, the outer elastic sealing part 43 and the inner elastic sealing part 42 can deform along the set direction after extrusion, ensuring the sealing performance while making the deformation direction controllable.

[0050] In some embodiments, a second inclined surface 44 is provided at the bottom of the inner wall of the piston 2, and the second inclined surface 44 presses against the lower outer side of the outer elastic sealing part 43.

[0051] First, the second inclined surface 44 at the bottom of the inner wall of the piston 2 can gradually press against the outer elastic sealing portion 43, and can transmit the acting force to the intermediate skeleton 41, and transmit the squeezing acting force to the inner elastic sealing portion 42 through the intermediate skeleton 41, so that the inner elastic sealing portion 42 is squeezed against the oil storage cylinder 1. The setting of the second inclined surface 44 can prevent the piston 2 from having a strong pressing force with the outer elastic sealing portion 43 during installation, causing the outer elastic sealing portion 43 to suddenly have a large deformation, but realizing a gradual deformation, and at the same time can further provide a deformation space for the extrusion of the outer elastic sealing portion 43.

[0052] In some embodiments, a chamfer structure 411 is provided at one end of the intermediate skeleton 41 close to the spring seat 3.

[0053] In practice, the chamfer structure 411 at one end of the intermediate skeleton 41 close to the spring seat 3 can expand the space, which is beneficial to absorbing the deformation of the sealing structure 4 during the assembly of the piston 2; for example, if there is a chamfer structure 411 on the inner side of the intermediate skeleton 41 and a chamfer structure 411 on the outer side, the inner chamfer structure 411 can absorb the inner elastic sealing portion 42 that is extruded and deformed, and the outer chamfer structure 411 can absorb the outer elastic sealing portion 43 that is extruded and deformed, and also prevent interference between the inner elastic sealing portion 42 and the outer elastic sealing portion 43 and the spring seat 3.

[0054] In addition, it should be noted that the outer elastic sealing portion 43 and the inner elastic sealing portion 42 on both sides of the intermediate skeleton 41 in the embodiments of the present invention adopt vulcanized rubber materials. Vulcanized rubber has characteristics such as non-sticky and not easy to break. Through a series of chemical reactions between rubber molecules and vulcanizing agents and other compounding agents, a three-dimensional spatial structure is formed in the raw rubber, so that it has high elasticity, heat resistance, tensile strength and insolubility in organic solvents and other characteristics, thereby improving the service life of the sealing structure 4.

[0055] The embodiments of the present invention also disclose a vehicle, including the above air spring shock absorber. The intermediate skeleton 41 of the sealing structure 4 presses against the spring seat 3, and the outer elastic sealing portion 43 of the sealing structure 4 cooperates with the piston 2. Through the pressing of the piston 2, the outer elastic sealing portion 43 is gradually deformed to play a sealing role. The inner elastic sealing portion 42 of the sealing structure 4 cooperates with the oil storage cylinder 1. Through the pressing of the oil storage cylinder 1, the inner elastic sealing portion 42 is gradually deformed to play a sealing role. The shape of the intermediate skeleton 41 remains unchanged, so that the pressing deformation is controllable. That is to say, the sealing structure 4 avoids the problem of air leakage caused by the sealing structure 4 in the prior art being not properly press-fitted or the press-fitting deformation being uncontrollable. That is, the risk of air leakage of the air spring shock absorber is reduced. When the vehicle is running, the air spring shock absorber can normally shock-absorb the vehicle, improving the comfort of the vehicle during driving.
