Description

Technical Field

[0001] This application relates to the technical field of energy storage, and in particular to a high-performance energy storage accumulator cup. Background Technology

[0002] Hydraulic accumulators are key components in hydraulic systems, primarily used to store hydraulic energy, mitigate pressure shocks, and absorb pressure pulsations. The piston cup, as the core sealing and energy transfer element within the hydraulic accumulator, directly affects the accumulator's operational stability, reliability, and output efficiency.

[0003] The end face of the accumulator cup that contacts the accumulator base is usually a smooth plane. Under long-term static or low-pressure conditions, the smooth surface is prone to sticking to the base shell. When the accumulator needs to work, a vacuum can easily form at the sticking point, causing the accumulator cup to be unable to respond quickly and resulting in sluggish action. This seriously affects the energy release speed and output efficiency of the accumulator, and fails to meet the response speed requirements of the hydraulic system. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a high-performance accumulator cup.

[0005] This application provides a high-performance accumulator cup, which adopts the following technical solution: A high-performance accumulator cup includes a cup body, which is a bowl-shaped structure with one end open and the other end closed, and the outer end face of the closed end of the cup body is provided with a concave-convex surface structure.

[0006] In one embodiment: the inner end face of the closed end of the leather cup body is provided with a concave-convex structure, and the concave-convex structure of the inner end face is opposite to that of the outer end face.

[0007] In one embodiment, the thickness of the bottom of the bowl body is greater than that of the bowl wall.

[0008] In one embodiment: the outer wall of the bowl body is provided with a plurality of reinforcing ribs, the reinforcing ribs extend along the axial direction of the bowl body, and the length of the reinforcing ribs is adapted to the height of the outer wall of the bowl body.

[0009] In one embodiment, one end of the reinforcing rib extends to the bottom of the bowl body.

[0010] In one embodiment: the reinforcing ribs are distributed at equal intervals around the circumference of the cup body.

[0011] In one embodiment, the cross-section of the reinforcing rib is semi-circular or trapezoidal.

[0012] In one embodiment: the uneven surface structure consists of a plurality of evenly distributed protrusions and / or pits.

[0013] In one embodiment: the uneven surface structure consists of a plurality of evenly distributed protrusions and pits, wherein the depth of the pits is adapted to the height of the protrusions, and the height of the protrusions is 0.8-1.3mm.

[0014] In one embodiment, the protrusions are hemispherical or cylindrical, and adjacent protrusions are equidistant from each other.

[0015] In summary, this application has the following beneficial effects: 1. The concave-convex surface structure can form multiple tiny gaps between the diaphragm cup and the base. When the accumulator starts working, the hydraulic medium can quickly enter the cavity between the diaphragm cup and the base through these tiny gaps, breaking the possible vacuum environment and effectively preventing the diaphragm cup from sticking to the base, ensuring that the diaphragm cup moves sensitively. 2. The addition of reinforcing ribs can significantly improve the structural strength and fatigue resistance of the diaphragm body, effectively preventing damage caused by stress concentration during high-frequency expansion and contraction.

[0018] The present application will be further described in detail below with reference to the accompanying drawings.

[0019] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0020] A high-performance accumulator cup, such as Figure 1 As shown, the high-performance accumulator cup is installed inside the hydraulic accumulator 10.

[0021] like Figure 2As shown, the high-performance accumulator cup includes a cup body 100, which is a bowl-shaped structure with one end open and the other end closed, wherein the closed end forms the bottom 110 of the cup.

[0022] The outer end face of the closed end of the leather cup body 100 has a concave-convex structure.

[0023] The convex-concave surface structure consists of multiple evenly distributed protrusions and / or pits. In this embodiment, the convex-concave surface structure is composed of multiple evenly distributed protrusions and pits simultaneously. The depth of the pits matches the height of the protrusions, and the height of the protrusions is 0.8-1.3mm. The protrusions are hemispherical or cylindrical, and adjacent protrusions are equidistantly spaced.

[0024] This structural design ensures effective sealing between the cup and the base, allows hydraulic fluid to quickly enter the gap, and avoids adverse effects on the sealing performance of the cup due to uneven structures.

[0025] In addition, to ensure the thickness and structural strength of the bowl bottom 110, the thickness of the bowl bottom 110 of the leather bowl body 100 is greater than that of the bowl wall 120. The inner end face of the closed end of the leather bowl body 100 can also be provided with a concave-convex structure, and the concave-convex structure of the inner end face is opposite to that of the outer end face.

[0026] like Figure 2 and Figure 3 As shown, the outer wall of the bowl 120 of the body 100 of the leather bowl is provided with a number of reinforcing ribs 200, and the cross-section of the reinforcing ribs 200 is semi-circular or trapezoidal.

[0027] The reinforcing rib 200 extends along the axial direction of the cup body 100, and the length of the reinforcing rib 200 is adapted to the height of the outer wall of the cup body 100. The setting of the reinforcing rib 200 can significantly improve the structural strength and fatigue resistance of the cup body 100, and effectively prevent the cup from breaking due to stress concentration during high-frequency expansion and contraction.

[0028] The number of reinforcing ribs 200 is 24-36, and the area of ​​the reinforcing ribs 200 on the cup wall 120 does not exceed 30%. This ensures sufficient strength improvement without excessively increasing the overall volume and wall thickness of the cup, thus avoiding affecting the fitting accuracy and operational sensitivity of the cup and the accumulator housing.

[0029] The reinforcing ribs 200 are evenly distributed around the circumference of the diaphragm body 100, so that the included angle between two adjacent reinforcing ribs 200 is equal, ensuring that the outer wall of the diaphragm is subjected to uniform force.

[0030] In addition, one end of the reinforcing rib 200 extends to the bottom 110 of the cup body 100, so that the reinforcing rib 200 will contact the base before the bottom 110 contacts the base, thus further improving the anti-stick connection effect.

[0031] The body 100 of the hydraulic cup is made of composite material, which has excellent oil resistance, wear resistance and elasticity, and can adapt to the working environment of the hydraulic system, extending the service life of the hydraulic cup. The reinforcing rib 200 is integrally molded with the body 100 of the hydraulic cup to ensure connection strength and prevent the reinforcing rib 200 from falling off during use.

[0032] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
