Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of automotive parts, specifically to rubber seals for high-strength automotive instrument components. Background Technology
[0002] In the automotive manufacturing industry, automotive instruments, as key vehicle components, encompass speedometers, tachometers, oil pressure gauges, water temperature gauges, fuel gauges, and charging gauges, and their stable operation is crucial. To ensure the sealing effect of automotive instruments and effectively prevent air and dust from entering the instrument's interior, strict sealing is often required. Rubber materials, due to their excellent elasticity and wear resistance, have become a common choice for automotive instrument seals. However, commercially available ordinary rubber seals generally suffer from low strength. During assembly, they are prone to tensile deformation due to insufficient strength, and may even crack, leading to leakage. They are also unable to withstand the pressure under complex automotive operating conditions, resulting in a short service life and failing to fully meet the high strength and high reliability requirements of automotive instruments for seals. Furthermore, automobiles operate under all-weather conditions and in complex and variable driving environments. This necessitates that rubber seals not only possess high strength but also good resistance to ozone aging, atmospheric aging, paint aging, and suitable low-temperature performance to cope with the impact of different environmental factors on seal performance. Therefore, the development of a high-strength rubber seal for automotive instrument components with excellent overall performance is urgently needed.
[0003] Application number CN202322007772.5 discloses a sealing structure for an automotive instrument panel. This sealing structure includes an L-shaped keel, with a mounting shell on its outer side and a panel fixing opening on its top. A sealing element is located on the inner side of the L-shaped keel, comprising a rubber component and a second L-shaped keel, the second L-shaped keel enclosing the rubber component. The first L-shaped keel is placed in an inverted L-shape, and the second L-shaped keel is placed in a regular L-shape. The rubber component is divided into a keel abutment portion and an instrument abutment portion. The keel abutment portion is located between the first and second L-shaped keels, and the instrument abutment portion is located inside the second L-shaped keel. The instrument abutment portion has a sealing lip. However, a drawback is that the device does not address the issue of material collapse and deformation after a period of use, which negatively impacts the sealing performance. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0025] Please see Figures 1-4 As shown, this utility model is a high-strength rubber seal for automotive instrument components, including an assembled silicone assembly 1, a splicing silicone assembly 2 installed inside the assembled silicone assembly 1, and a support ring assembly 3 installed between the assembled silicone assembly 1 and the splicing silicone assembly 2.
[0026] The splicing silicone assembly 2 includes a splicing silicone body 201, a limiting top plate 202 is fixedly installed on the top of the splicing silicone body 201, and a limiting bottom plate 203 is fixedly installed on the bottom of the splicing silicone body 201. A limiting insert plate 204 is fixedly installed around the top of the limiting bottom plate 203.
[0027] By installing the splicing silicone component 2 inside the device, the device can provide a better long-lasting and non-collapse-resistant working effect when sealed.
[0028] The assembled silicone assembly 1 includes a silicone airbag 101. A dust-proof lip 102 is fixedly installed around the outer wall of the silicone airbag 101. The silicone airbag 101 is ring-shaped, and there are several dust-proof lips 102. The silicone airbag 101 in the assembled silicone assembly 1 is ring-shaped, and the dust-proof lips 102 around its outer wall can effectively block dust and impurities from entering the instrument components, thus playing a preliminary dustproof role.
[0029] The top inner wall of the silicone airbag 101 is provided with an assembly limiting groove 1011, and the bottom of the silicone airbag 101 is provided with an assembly slot 1012. The assembly slot 1012 is provided with a limiting insert plate 204 inside.
[0030] An assembly strip 2011 is fixedly installed on the outer wall of the splicing silicone body 201. A fixing suction hole 2031 is opened at the bottom of the limiting base plate 203. The assembly strip 2011 is limited and installed inside the assembly limiting groove 1011. The splicing silicone body 201 of the splicing silicone assembly 2 and the assembly silicone assembly 1 achieve precise limiting installation through the cooperation of the assembly strip 2011, the assembly limiting groove 1011, the limiting insert plate 204 and the assembly slot 1012, ensuring the stability of the overall structure of the sealing component.
[0031] The support ring assembly 3 includes a septum body 301, which is installed in the cavity between the silicone airbag 101 and the limiting base plate 203.
[0032] The septum body 301 includes a ceramic septum layer 3012. A protective cover layer 3011 is fixedly installed on the top of the ceramic septum layer 3012, and an anti-slip material layer 3013 is fixedly installed on the bottom of the ceramic septum layer 3012. The septum body 301 in the support ring assembly 3 is installed in the cavity between the silicone airbag 101 and the limiting base plate 203. Its ceramic septum layer 3012 can enhance the strength and heat insulation performance of the seal. The protective cover layer 3011 and the anti-slip material layer 3013 play a protective and anti-slip role, respectively, further improving the reliability and applicability of the seal.
[0033] High-strength rubber seals for automotive instrument components primarily achieve sealing, support, and protection functions through the structural fit between various components. In the assembled silicone assembly 1, the silicone airbag 101 is ring-shaped, and its outer wall's dust-proof lip 102 effectively prevents dust and impurities from entering the instrument component, providing initial dust protection. The splicing silicone body 201 of the splicing silicone assembly 2, along with the assembled silicone assembly 1, achieves precise positioning and installation through the cooperation of the assembly strip 2011, assembly limiting groove 1011, limiting insert 204, and assembly slot 1012, ensuring the overall structural stability of the seal. In the support ring assembly 3, the septum body 301 is installed in the cavity between the silicone airbag 101 and the limiting base plate 203. Its ceramic septum layer 3012 enhances the strength and heat insulation performance of the seal, while the protective layer 3011 and anti-slip material layer 3013 provide protection and anti-slip properties, further improving the reliability and applicability of the seal. Meanwhile, the fixing suction hole 2031 at the bottom of the limiting base plate 203 can enhance the fit between the seal and the mounting surface of the instrument component through adsorption, thereby improving the sealing effect. In the workflow, the assembly silicone component 1, splicing silicone component 2, and support ring component 3 are prepared. Each component is checked for integrity and damage, ensuring that key components such as the silicone airbag 101, splicing silicone body 201, and septum body 301 are free from deformation and damage. The assembly strip 2011 on the outer wall of the splicing silicone body 201 is aligned with the assembly limiting groove 1011 on the inner wall of the top of the silicone airbag 101 and slowly inserted for initial positioning. At the same time, the limiting insert plate 204 at the top of the limiting base plate 203 is inserted into the assembly slot 1012 at the bottom of the silicone airbag 101, so that the splicing silicone component 2 is securely installed inside the assembly silicone component 1. The septum body 301 is placed between the silicone airbag 101 and the limiting base plate 203. Within the cavity, ensure the accurate positioning of the septum body 301, and the correct orientation of the ceramic septum layer 3012, protective cover layer 3011, and anti-slip material layer 3013, providing good support and protection. Install the assembled rubber seal onto the corresponding position of the automotive instrument component. Utilize the fixing suction hole 2031 at the bottom of the limiting base plate 203 to adhere it to the mounting surface. Further adjust the seal's position to ensure a tight fit between the seal and the instrument component. All components work together to effectively seal, protect, and support the instrument component. During vehicle operation, the dust-proof lip 102 continuously blocks external dust and impurities; the splicing silicone assembly 2 and support ring assembly 3 maintain the stability of the seal structure; the septum body 301 performs its functions of enhancing strength and providing heat insulation; simultaneously, the seal relies on its own structure to seal the instrument component, ensuring its normal operation in a stable environment.
