Description

Technical Field

[0001] This utility model relates to the field of automotive sleeve technology, and in particular to wear-resistant and heat-insulating automotive sleeves. Background Technology

[0002] Wear-resistant and heat-insulating automotive sleeves are protective components specifically designed for the complex operating conditions of automobiles. Utilizing a multi-layered composite structure, they combine excellent heat insulation and wear resistance, effectively blocking high-temperature radiation from the engine compartment and preventing wiring harnesses, oil lines, and other components from aging due to overheating. They also withstand long-term friction, oil erosion, and mechanical vibration. Easy to install and adaptable to pipelines of different diameters, they are widely used in the protection of battery harnesses in new energy vehicles and the surrounding pipelines of exhaust pipes in traditional fuel vehicles. They significantly improve the safety and lifespan of automotive electrical systems and are a key solution for protecting components in high-temperature vehicle environments.

[0003] Existing sleeves are mostly designed with a fixed inner diameter. When encountering wire harnesses of different diameters, they either cannot be wrapped or the fit after wrapping is poor, affecting the protective effect. They are difficult to adapt to the diverse spatial layout of the car interior and the installation requirements of different wire harnesses. Therefore, we propose wear-resistant and heat-insulating automotive sleeves. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant and heat-insulating automotive sleeve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant and heat-insulating automotive sleeve, comprising a wear-resistant and heat-insulating mechanism and connecting mechanisms disposed at its upper and lower ends. The wear-resistant and heat-insulating mechanism includes a wear-resistant textile sleeve. Multiple sets of limiting buckles are fixedly installed on the inner wall of the wear-resistant textile sleeve near its edge. A silicone rubber heat-insulating jacket is fixedly installed on the outer wall of the wear-resistant textile sleeve. Multiple sets of first sliding grooves and second sliding grooves are formed on the outer wall of the silicone rubber heat-insulating jacket. Each set of second sliding grooves is connected to an mounting component through an arc-shaped sliding block. A buckle groove is formed inside the mounting component.

[0006] As a preferred embodiment, the wear-resistant textile sleeve can be broken at both ends and rolled into a circle. The wear-resistant textile sleeve is made of nylon, and the silicone rubber insulation jacket is made of silicone rubber.

[0007] As a preferred embodiment, the second sliding groove is located inside the first sliding groove, the arc-shaped sliding block is slidably connected inside the second sliding groove, the mounting component is fixedly installed on the outer surface of the arc-shaped sliding block, and the outer wall of the mounting component is slidably connected to the inner wall of the first sliding groove.

[0008] As a preferred embodiment, the size of the buckle groove is adapted to the limit buckle, and a flexible retaining ring is fixedly installed on the surface of the buckle groove. The number of buckle grooves and limit buckles is the same, and they are located on the same horizontal line in the longitudinal direction.

[0009] As a preferred embodiment, the connecting mechanism includes an upper connector and a lower connector. The upper connector is fixedly installed on the upper end of the wear-resistant textile sleeve. An upper hook and loop fastener is fixedly installed on the outer wall of the upper connector, and an upper hook and loop fastener is fixedly installed on the inner wall of the upper connector.

[0010] As a preferred embodiment, the lower connector is fixedly installed at the lower end of the wear-resistant textile sleeve, and a lower Velcro smooth surface is fixedly installed on the inner wall of the lower connector. The upper connector is smaller than the lower connector.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the design of the wear-resistant and heat-insulating mechanism, the wear-resistant textile sleeve made of nylon material has high strength and tear resistance, which can effectively resist the friction and wear between the wiring harness and surrounding components during the operation of the car. The silicone rubber insulation jacket, with its high temperature resistance, aging resistance and heat insulation performance, can withstand the high temperature environment such as the engine compartment, while reducing heat transfer and providing a stable working temperature for the internal wiring harness, significantly improving the durability and protection of the sleeve. The first and second sliding grooves on the silicone rubber insulation jacket, together with the arc-shaped sliding block and the sliding connection with the mounting part, allow the mounting part to be freely adjusted along the axial direction of the sleeve. The limiting buckle on the inner wall cooperates with the buckle groove of the mounting part, and with the anti-loosening flexible retaining ring, it can adapt to wiring harnesses of different diameters.

[0013] 2. Through the designed connection mechanism, the wear-resistant and heat-insulating automotive sleeve can achieve quick and easy connection during installation. Simply stick the rough side of the upper Velcro to the smooth side of the lower Velcro, and the end of the sleeve can be connected without the need for complicated tools, which greatly improves the installation efficiency. It is especially suitable for time-sensitive scenarios such as automotive repair and modification. The design of the upper connector being smaller than the lower connector allows the sleeve to be nested during connection. When multiple sets of sleeves are used, the size difference can achieve tight nesting, improve the stability of the overall structure and space utilization, and meet the diverse protection requirements of complex automotive wiring environments.

[0022] 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.

[0023] Please see the appendix Figure 1 - Appendix Figure 5 The wear-resistant and heat-insulating automotive sleeve includes a wear-resistant and heat-insulating mechanism 1 and a connecting mechanism 2 disposed at its upper and lower ends. The wear-resistant and heat-insulating mechanism 1 includes a wear-resistant textile sleeve 101. Multiple sets of limiting buckles 105 are fixedly installed on the inner wall of the wear-resistant textile sleeve 101 near the edge. A silicone rubber heat-insulating jacket 102 is fixedly installed on the outer wall of the wear-resistant textile sleeve 101. Multiple sets of first sliding grooves 103 and second sliding grooves 104 are opened on the outer wall of the silicone rubber heat-insulating jacket 102. The multiple sets of second sliding grooves 104 are all connected to the mounting parts 107 through arc-shaped sliding blocks 106. The mounting parts 107 have buckle grooves 108 inside.

[0024] The wear-resistant textile sleeve 101 can be broken at both ends and rolled into a circle. The wear-resistant textile sleeve 101 is made of nylon, and the silicone rubber insulation jacket 102 is made of silicone rubber.

[0025] The wear-resistant textile sleeve 101 has two disconnected ends and can be rolled into a circle. This design facilitates quick wrapping of the wire harness without disassembling other automotive parts, greatly reducing the difficulty of installation.

[0026] The second sliding groove 104 is located inside the first sliding groove 103. The arc-shaped sliding block 106 is slidably connected inside the second sliding groove 104. The mounting part 107 is fixedly installed on the outer surface of the arc-shaped sliding block 106. The outer wall of the mounting part 107 is slidably connected to the inner wall of the first sliding groove 103.

[0027] The component consisting of mounting part 107 and arc-shaped sliding block 106 can slide smoothly along the first sliding groove 103 and the second sliding groove 104.

[0028] The size of the buckle groove 108 is adapted to the limit buckle 105. The surface of the buckle groove 108 is fixedly installed with an anti-detachment flexible retaining ring 109. The number of buckle grooves 108 and limit buckles 105 is the same, and they are located on the same horizontal line in the longitudinal direction.

[0029] The limiting buckle 105 cooperates with the buckle groove 108 of the mounting part 107, and together with the anti-detachment flexible retaining ring 109, it can not only realize the quick positioning and installation of the sleeve, but also maintain a stable connection in the vibration environment of the car driving, prevent the sleeve from shifting or falling off, and ensure the continuity of the protective effect.

[0030] Specifically, the nylon wear-resistant textile sleeve 101 has high strength and tear resistance, effectively resisting friction and wear between the wiring harness and surrounding components during vehicle operation. The silicone rubber insulation jacket 102, with its high temperature resistance, aging resistance, and heat insulation properties, can withstand high-temperature environments such as the engine compartment, while reducing heat transfer and providing a stable working temperature for the internal wiring harness, significantly improving the durability and protective capabilities of the sleeve. The first sliding groove 103 and the second sliding groove 104 on the silicone rubber insulation jacket 102, together with the arc-shaped sliding block 106 and the sliding connection with the mounting part 107, allow the mounting part 107 to be freely adjusted along the sleeve axis. The limiting buckle 105 on the inner wall cooperates with the buckle groove 108 of the mounting part 107, and together with the anti-detachment flexible retaining ring 109, it can adapt to wiring harnesses of different diameters.

[0031] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 6 and attached Figure 7 The connecting mechanism 2 includes an upper connector 201 and a lower connector 204. The upper connector 201 is fixedly installed on the upper end of the wear-resistant textile sleeve 101. An upper hook and loop fastener 202 is fixedly installed on the outer wall of the upper connector 201, and an upper hook and loop fastener smooth surface 203 is fixedly installed on the inner wall of the upper connector 201.

[0032] The lower connector 204 is fixedly installed at the lower end of the wear-resistant textile sleeve 101. The lower Velcro smooth surface 205 is fixedly installed on the inner wall of the lower connector 204. The size of the upper connector 201 is smaller than that of the lower connector 204.

[0033] The smooth surface 203 of the upper hook and loop fastener can fit together with the rough surface 202 of the upper hook and loop fastener when the upper connector 201 is rolled up, ensuring that no wrinkles will appear during winding. The tight fit of the hook and loop fastener can effectively fill the gaps at the sleeve connection, prevent the intrusion of external impurities such as dust, moisture, and oil, avoid damage to the internal wire harness due to environmental factors, and further enhance the protective effect of the sleeve. At the same time, this sealed connection method can also reduce heat loss or transfer through the interface, ensuring the integrity of the thermal insulation performance.

[0034] Specifically, the wear-resistant and heat-insulating automotive sleeve can achieve quick and easy connection during installation. Simply stick the upper hook and loop fastener rough side 202 and the lower hook and loop fastener smooth side 205 together. No complicated tools are needed to complete the connection of the sleeve, which greatly improves the installation efficiency. It is especially suitable for time-sensitive scenarios such as automotive repair and modification. The design of the upper connector 201 being smaller than the lower connector 204 allows the sleeve to be nested during connection. When multiple sets of sleeves are used, the size difference can achieve tight nesting, improve the stability of the overall structure and space utilization, and meet the diverse protection requirements of complex automotive wiring environments.

[0035] The working principle of this utility model is as follows: This utility model is a wear-resistant and heat-insulating automotive sleeve. First, the retractable wear-resistant textile sleeve 101 is unfolded, and the automotive wiring harness or pipeline that needs to be protected is placed inside it. The wear-resistant textile sleeve 101 is broken at both ends and wraps around the wiring harness. Because its nylon material has good wear resistance, it can initially protect the wiring harness from friction. The silicone rubber heat-insulating jacket 102 is placed on the outer wall of the wear-resistant textile sleeve 101. The heat insulation performance of the silicone rubber heat-insulating jacket 102 can isolate the external high temperature and prevent the wiring harness from being damaged by high temperature.

[0036] According to the actual installation requirements inside the car, the arc-shaped sliding block 106 slides along the second sliding groove 104, which drives the mounting part 107 fixed on its outer surface to move. The outer wall of the mounting part 107 slides synchronously on the inner wall of the first sliding groove 103 until the mounting part 107 reaches the appropriate fixed position.

[0037] Align the buckle groove 108 inside the mounting piece 107 with the limiting buckle 105 on the inner wall of the wear-resistant textile sleeve 101, press the mounting piece 107 so that the limiting buckle 105 is embedded in the buckle groove 108, and the anti-detachment flexible retaining ring 109 on the surface of the buckle groove 108 further locks the limiting buckle 105 to prevent the wear-resistant heat insulation mechanism 1 from loosening, so as to achieve a stable installation of the wear-resistant heat insulation mechanism 1 inside the car.

[0038] When the wire harness is long, the upper hook and loop fastener rough surface 202 of the upper end connector 201 of one set of sleeves is aligned and attached to the lower hook and loop fastener smooth surface 205 of the lower end connector 204 of another set of sleeves. The hook and loop fasteners are tightly attached to complete the connection between the upper and lower ends of the wear-resistant and heat-insulating automotive sleeve, effectively filling the gaps at the connection, preventing the intrusion of impurities such as dust and moisture, and ensuring the heat insulation performance.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
