Description

Technical Field

[0001] This utility model relates to the field of interface protection technology for aluminum fuel cells, specifically, to an electrical interface protection structure for aluminum fuel cells. Background Technology

[0002] During operation, aluminum fuel cells need to output electrical energy and transmit signals through an electrical interface. This interface is usually in a complex working environment, which may be corroded by external moisture, dust and corrosive gases, as well as structural impacts caused by thermal expansion and contraction or mechanical vibration.

[0003] However, most existing electrical interfaces are encapsulated with a single sleeve or protective cover, and their sealing effect depends on a single sealing ring or gasket. When the interface is in a long-term working state, the sealing ring is prone to aging, displacement or permanent deformation due to compression, which leads to sealing failure. When external media enter the interface, it can easily cause electrical short circuits, corrosion and poor contact. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrical interface protection structure for aluminum fuel cells, comprising multiple protective shells, multiple elastic shells disposed between the multiple protective shells, a groove being provided inside the protective shell, an elastic component being disposed inside the groove, a filling layer being disposed on the side of the elastic component away from the groove, a rubber ring being embedded in the inner wall of the filling layer, a fixing ring being fixedly connected to the front and rear surfaces of the multiple protective shells, a clamp being disposed inside the fixing ring, and the multiple protective shells and multiple elastic shells being arranged alternately to form a multi-level sealing cavity distributed sequentially along the axial direction.

[0006] Preferably, the elastic component includes an annular groove formed on the outer wall of the elastic component, a spring is fixedly connected inside the annular groove, a damping block is fixedly connected to the end of the spring away from the annular groove, and one side of the damping block is fixedly connected to the inner wall of the groove.

[0007] Preferably, a fixing groove is provided on the side of the protective shell adjacent to the elastic shell, a fixing block is engaged inside the fixing groove, and the side of the fixing block away from the fixing groove is fixedly connected to the elastic shell.

[0008] Preferably, the upper interior of the rubber ring is provided with an arc-shaped portion.

[0009] Preferably, the filler layer is made of fluororubber composite material.

[0010] Preferably, each sealing cavity consists of an independent sealing structure formed by a rubber ring and a filling layer.

[0011] Compared with existing technologies, this utility model uses a multi-level sealing combination design of protective shell, elastic shell, filling layer and rubber ring to form a multi-level independent sealing cavity distributed sequentially along the axial direction. It can maintain the long-term sealing reliability of electrical interface under complex working conditions such as high temperature, vibration and high pressure difference. Through the synergistic effect of elastic component, damping block and filling layer, thermal stress compensation and vibration absorption are achieved, reducing the risk of fatigue damage to sealing interface. At the same time, by using fluororubber composite material for filling layer, it has both high temperature resistance and high resilience, thereby improving the overall protection performance and extending the service life of electrical interface.

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 , Figure 2 and Figure 3An embodiment of this utility model provides an electrical interface protection structure for an aluminum fuel cell, including multiple protective shells 10, multiple elastic shells 11 disposed between the multiple protective shells 10, a groove 17 is formed inside the protective shell 10, an elastic component 16 is disposed inside the groove 17, a filling layer 15 is disposed on the side of the elastic component 16 away from the groove 17, a rubber ring 14 is embedded in the inner wall of the filling layer 15, a fixing ring 13 is fixedly connected to the front and rear surfaces of the multiple protective shells 10, a clamp 12 is disposed inside the fixing ring 13, and the multiple protective shells 10 and the multiple elastic shells 11 are arranged alternately to form a multi-level sealing cavity distributed sequentially along the axial direction.

[0016] According to the above technical solution, multiple protective shells 10 and multiple elastic shells 11 are arranged in an alternating manner to form a multi-level sealing cavity distributed sequentially along the axial direction. The protective shells 10 provide overall support and rigid constraint in the axial direction, and the elastic shells 11 form a flexible transition interface in the radial direction. The elastic component 16 in the groove 17 can generate deformation compensation under external mechanical vibration or thermal expansion and contraction, avoiding sealing failure caused by interface thermal stress or external impact. Through the composite sealing design of the filling layer 15 and the rubber ring 14, an independent airtight interface is formed in the multi-level sealing cavity, so that reliable sealing and protection performance at the interface can still be maintained under large pressure difference, temperature fluctuation and external vibration.

[0017] like Figure 3 and Figure 4 As shown, the elastic component 16 includes an annular groove 161 formed on the outer wall of the elastic component 16. A spring 162 is fixedly connected inside the annular groove 161. A damping block 163 is fixedly connected to one end of the spring 162 away from the annular groove 161. One side of the damping block 163 is fixedly connected to the inner wall of the groove 17.

[0018] According to the above technical solution, a spring 162 is embedded in the annular groove 161 on the outer wall of the elastic component 16. The spring 162 can store and release energy when compressed or stretched. The fixed connection between the damping block 163 and the inner wall of the groove 17 can provide speed suppression during the reset process of the spring 162, reducing the high-frequency vibration response of the elastic component 16. When the electrical interface is subjected to periodic loads or impact loads, the risk of interface fatigue damage can be reduced and the service life of the sealing component can be extended without affecting the sealing performance.

[0019] like Figure 5 As shown, a fixing groove 19 is provided on the side of the protective shell 10 adjacent to the elastic shell 11. A fixing block 20 is snapped into the inside of the fixing groove 19. The side of the fixing block 20 away from the fixing groove 19 is fixedly connected to the elastic shell 11.

[0020] According to the above technical solution, a fixing groove 19 is provided on the side of the protective shell 10 adjacent to the elastic shell 11. Through the reliable connection between the fixing block 20 and the elastic shell 11, the protective shell 10 and the elastic shell 11 are stably positioned, avoiding the displacement of the sealing interface caused by the loosening of the protective shell 10 and the elastic shell 11, thereby maintaining the stable shape of the multi-stage sealing cavity and improving the structural integrity and sealing reliability under long-term use conditions.

[0021] like Figure 6 As shown, an arc-shaped portion 18 is provided inside the upper part of the rubber ring 14.

[0022] According to the above technical solution, the upper part of the rubber ring 14 is provided with an inner arc-shaped part 18. When radially pressed, the arc-shaped part 18 can form a non-linear stress distribution, making the contact pressure between the rubber ring 14 and the inner wall of the filling layer 15 more uniform, avoiding local stress concentration caused by conventional right-angle contact surfaces, improving the resilience and sealing fit of the rubber ring 14, and further reducing the risk of micro-leakage at the long-term sealing interface.

[0023] In one embodiment, the filler layer 15 is specifically configured as a fluororubber composite material.

[0024] According to the above technical solution, the filler layer 15 is made of fluororubber composite material, which achieves a balance between high temperature resistance, corrosion resistance and high resilience. Fluororubber maintains chemical stability in high temperature fuel environment, preventing hardening or failure due to material aging. Its composite structure gives the filler layer 15 higher compression deformation recovery ability, so that it can still maintain high air tightness and tear resistance under multiple thermal cycles and pressure shock conditions.

[0025] In one embodiment, specifically, each sealing cavity is formed by a rubber ring 14 and a filling layer 15 together to form an independent sealing structure.

[0026] According to the above technical solution, each sealing cavity is composed of a rubber ring 14 and a filling layer 15 forming an independent sealing structure. The sealing interfaces are isolated from each other, and other sealing cavities can still maintain an intact working state when a single-stage seal is damaged or fails. Through the multi-stage redundant sealing design, the overall sealing reliability of the protective structure is significantly improved under complex operating conditions such as high-frequency vibration, thermal shock, and high pressure differential, making it suitable for the electrical interface protection requirements of long-term aluminum fuel cells.

[0027] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
