Description

Technical Field

[0001] This utility model relates to the field of composite material technology, and in particular to a pressure-resistant silicone composite structure. Background Technology

[0002] Composite materials are new materials created by combining different material components using advanced material preparation technologies. The matrix materials of composite materials are divided into two main categories: metals and non-metals. ① Commonly used metal matrices include aluminum, magnesium, copper, titanium and their alloys; ② Non-metal matrices mainly include synthetic resins, rubber, ceramics, graphite, carbon, silicone, etc.

[0003] Silicone possesses the properties of organic polymer elastomers while also exhibiting the wide adaptability to high and low temperatures characteristic of inorganic materials. Silicone products have become the preferred material in fields such as power supplies, automotive electronics, motor control, power semiconductors, and relays. However, for some applications requiring high circumferential pressure resistance (such as when used as bottom support components for precision equipment), silicone alone is insufficient. It is necessary to add some metal materials to the silicone to increase its strength and compressive strength. Utility Model Content

[0035] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Example 1

[0037] Please refer to this carefully. Figures 1 to 5 The pressure-resistant silicone composite structure of this utility model includes a silicone body 100, a keel assembly 200 is provided inside the silicone body 100, and a rebound assembly 300 extending to the outside is provided inside the keel assembly 200.

[0038] The above structural design increases the strength and bending resistance of the silicone body 100 through the keel component 200 and increases the compressive strength of the silicone body 100 through the spring component 300. During the preparation process, the spring component 300 can be installed on the keel component 200, and then the assembled spring component 300 and keel component 200 are placed into a mold. After the silicone rubber is injected, the composite structure of the spring component 300 and keel component 200 wrapped by the silicone body 100 can be obtained.

[0039] Please refer to this carefully. Figures 2 to 5 As shown, there are four sets of keel components 200. The four sets of keel components 200 are distributed in an equidistant array along the circumferential direction of the spring component 300. Each keel component 200 includes a rubber buffer pad 210 that is connected to the inside of the silicone body 100.

[0040] It should be noted that, in this embodiment, since it is integral injection molding, the rubber buffer pad 210 is only used for silicone composite structures of customized sizes according to actual needs. For silicone composite structures of non-custom sizes that may be subject to cutting, the rubber buffer pad 210 is removed.

[0041] A stainless steel connecting rod 220 is fitted to the end of the rubber buffer pad 210 away from the silicone body 100. The stainless steel connecting rod 220 extends along the length of the silicone body 100. The keel assembly 200 also includes a threaded hole 240 opened on the outer wall of the stainless steel connecting rod 220. A locking bolt 230 is fitted inside the threaded hole 240.

[0042] The threaded hole 240 extends from the outer wall of the stainless steel connecting rod 220 to the interior of the stainless steel connecting rod 220 and is connected to the through hole. The threaded hole 240 is distributed in an equidistant array along the length of the stainless steel connecting rod 220.

[0043] The spring-loaded assembly 300 includes a first spring-loaded steel wire rope 310 that contacts the interior of the keel assembly 200. The first spring-loaded steel wire rope 310 extends spirally along the length of the keel assembly 200. The stainless steel connecting rod 220 has through holes that match the first spring-loaded steel wire rope 310. The positions of the through holes inside the four sets of stainless steel connecting rods 220 are distributed along the spiral path of the first spring-loaded steel wire rope 310. Both ends of the stainless steel connecting rod 220 are equipped with rubber buffer pads 210. The through holes are generally arc-shaped with lower sides and higher middle, and the through holes penetrate both sides of the stainless steel connecting rod 220. The through holes are evenly distributed in an array along the length of the stainless steel connecting rod 220, and the inner diameter of the through holes matches the outer diameter of the first spring-loaded steel wire rope 310.

[0044] The above structural design facilitates the sequential passing of the first spring-loaded steel wire rope 310 through four stainless steel connecting rods 220 during the manufacturing process, and the above action is repeated continuously along the spiral extension direction. After passing through the stainless steel connecting rods 220, the first spring-loaded steel wire rope 310 is fixed inside the stainless steel connecting rods 220 by locking bolts 230 and threaded holes 240. When the first spring-loaded steel wire rope 310 passes through the last stainless steel connecting rod 220, the assembly between the keel assembly 200 and the spring assembly 300 is completed, forming a pressure-resistant spring mechanism.

[0045] Through the cooperation between the keel assembly 200 and the spring assembly 300, when the external pressure compresses the silicone body 100, the silicone body 100 compresses the pressure-resistant spring mechanism. The stainless steel connecting rod 220 is the first to be compressed. After being compressed, the stainless steel connecting rod 220 moves downward, thereby driving the first spring wire rope 310 to move. The first spring wire rope 310 generates a large amount of friction during the displacement process, thereby playing the role of relieving pressure.

[0046] Example 2

[0047] Please refer to this carefully. Figure 4 and Figure 5 As shown, the rebound assembly 300 also includes a second rebound steel wire rope 320, which is offset from the first rebound steel wire rope 310 and is disposed inside the stainless steel connecting rod 220. The installation angles of the second rebound steel wire rope 320 and the first rebound steel wire rope 310 differ by 180 degrees. Both the first rebound steel wire rope 310 and the second rebound steel wire rope 320 are made of metal rope braiding.

[0048] In this embodiment, a second set of spring-loaded steel wire ropes 320 is added, and the second spring-loaded steel wire ropes 320 are staggered with the first spring-loaded steel wire ropes 310. When subjected to pressure, the pressure is dispersed, thereby greatly increasing the overall pressure resistance and spring-loaded effect of the structure.

[0049] Example 3

[0050] Please refer to this carefully. Figures 1 to 3 As shown, the silicone body 100 includes a silicone circumferential plate 110. The silicone circumferential plate 110 has a limiting groove 140 that matches the rubber buffer pad 210. A silicone end plate 120 is provided at one end of the limiting groove 140 away from the silicone circumferential plate 110. A support column 130 is installed at the center of the silicone end plate 120. The support column 130 extends vertically along the length direction of the silicone circumferential plate 110.

[0051] The sidewall of the limiting groove 140 fits against the sidewall of the rubber buffer pad 210, and the thickness of the limiting groove 140 matches the thickness of the rubber buffer pad 210. The silicone circumferential plate 110 has two sets of support columns 130 inside.

[0052] The thickness of the silicone end plate 120 is greater than the thickness of the silicone circumferential plate 110. There are two sets of silicone end plates 120 and four sets of silicone circumferential plates 110. The two sets of silicone end plates 120 and the four sets of silicone circumferential plates 110 form a sealed chamber. The two ends of the support column 130 are connected to the adjacent surfaces of the two sets of silicone end plates 120.

[0053] Please refer to this carefully. Figure 3 In this embodiment, the silicone body 100 can be prepared as a preform, and the silicone circumferential plate 110, silicone end plate 120 and support column 130 can be pre-molded. Then, the keel assembly 200 and the spring assembly 300 can be installed inside the silicone body 100.

[0054] During the preparation process, the keel assembly 200 and the spring-loaded assembly 300 are installed for later use. The support column 130 is placed in the center of the keel assembly 200, so that the outer wall of the support column 130 is in contact with the outer wall of the keel assembly 200. Then, the two ends of the support column 130 and the keel assembly 200 are fixedly connected to the silicone end plate 120 (the connection method can be the hot-melt connection between the support column 130 and the silicone end plate 120, but it is not limited to hot-melt; any connection between the support column 130 and the silicone end plate 120 is acceptable). Then, the silicone circumferential plate 110 is connected to the silicone end plate 120 (the connection method is the same as above). In some embodiments of this utility model, in order to prevent it from being weak, a thin layer of silicone can be injected again on the outer wall to make it more robust, thus completing the preparation of the pressure-resistant silicone composite structure.

[0055] The above-mentioned structural design effectively reduces the cooling time during the injection molding process, allowing multiple departments to start production simultaneously and assemble at the end, thus improving production efficiency. Furthermore, due to the addition of a cavity to the springback component 300, its springback effect and pressure resistance are superior to those of Embodiment 1.

[0056] Example 4

[0057] Please refer to this carefully. Figure 6 and Figure 7 To address certain needs, by appropriately reducing the number of stainless steel connecting rods 220, for example, by reducing two stainless steel connecting rods 220 in this embodiment, the compressive strength of the silicone body 100 can be reduced, thereby achieving adjustable compressive strength and resilience of the silicone body 100. Similarly, by appropriately reducing the number of locking bolts 230, for example, by selecting the middle set of locking bolts 230 in the three sets of locking bolts 230 in this embodiment to not fix them, and increasing the movable spacing between the first rebound steel wire ropes 310, the above effect can also be achieved.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
