Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of new energy vehicles, and in particular to a sealing gasket, a heat insulation structure and a vehicle. Background Art
[0002] As a new generation of transportation, new energy vehicles (NEVs) offer unparalleled advantages over traditional vehicles in terms of energy conservation, emissions reduction, and reducing human dependence on traditional fossil fuels. However, since NEVs lack engines and cannot utilize engine heat, they require a heating system. A vehicle's heating system typically consists of a heater, a heater controller box, a compressor controller box, and a compressor. During the heating process, heat from the heater housing is transferred through the heater controller box housing and the compressor controller box housing to the compressor, causing the compressor to overheat, which in turn affects both intake and exhaust air.
[0003] In the prior art, a space is usually created between the heater controller box housing and the compressor controller box housing to form an air layer between the heater controller box housing and the compressor controller box housing to provide insulation. However, since there needs to be a gap between the heater controller box housing and the compressor controller box housing, the installation of the heating system is difficult and condensed water is formed between the heater controller box housing and the compressor controller box housing after the hot air is cooled. The condensed water enters the interior of the heater controller box housing and the compressor controller box housing, posing a risk of damaging the equipment. Utility Model Content

[0025] Please refer to Figure 1 and Figure 2On the one hand, this embodiment provides a sealing gasket 1 for installation between a first outer member 2 and a second outer member 3. The sealing gasket 1 is made of a flexible material and has a first contact surface 14 and a second contact surface 15 spaced apart and disposed opposite each other. The first contact surface 14 is configured to mate with the first outer member 2, and the second contact surface 15 is configured to mate with the second outer member 3. At least one of the first contact surface 14 and the second contact surface 15 is provided with a first thermal insulation groove 11, which is filled with a thermal insulation medium. With this arrangement, the sealing gasket 1 made of a flexible material has excellent sealing properties, preventing condensation from seeping between the first and second outer members 2 and 3 and damaging the equipment. The thermal insulation medium contained in the first thermal insulation groove 11 reduces the contact area between the first and second outer members 2 and 3 and the sealing gasket 1. At the same time, the thermal insulation medium can isolate heat transfer between the first and second outer members 2 and 3, resulting in an excellent thermal insulation effect for the sealing gasket 1.
[0026] In this embodiment, the insulating medium is air. This arrangement utilizes air's high thermal resistance to further enhance the insulating effect of the sealing gasket 1. During assembly, air naturally fills the insulation groove, eliminating the need for additional equipment. This facilitates installation of the sealing gasket 1 and reduces manufacturing costs. In other embodiments, the insulating medium can also be insulating cotton.
[0027] Preferably, the flexible material is aerogel, which has high thermal resistance, thus providing the sealing gasket 1 with excellent thermal insulation. In other embodiments, the flexible material may also be rubber. It should be understood that this embodiment does not limit the material of the sealing gasket 1.
[0028] Optionally, the sealing gasket 1 is annular and is provided with a plurality of mounting holes 13. The plurality of mounting holes 13 are used to pass connecting parts, and the plurality of mounting holes 13 are spaced apart along the circumference of the sealing gasket 1. With such a configuration, a through hole is formed in the center of the annular sealing gasket 1, which increases the air between the first outer part 2 and the second outer part 3, further enhancing the thermal insulation effect. At the same time, the provision of the mounting holes 13 facilitates the sealed connection between the first outer part 2 and the second outer part 3 and the sealing gasket 1. The plurality of mounting holes 13 also serve as a limiting function, locking the relative positions of the first outer part 2, the sealing gasket 1, and the second outer part 3, so that the first contact surface 14 is tightly fitted with the first outer part 2, and the second contact surface 15 is tightly fitted with the second outer part 3, further enhancing the sealing effect and the thermal insulation effect.
[0029] Specifically, the connecting member is a bolt, which passes through the corresponding mounting holes 13 of the first outer member 2, the sealing gasket 1, and the second outer member 3 in sequence and is tightened with a nut. It should be understood that the connecting member can also be a screw, a connecting pin, etc. The connecting member only needs to seal the first outer member 2, the second outer member 3, and the sealing gasket 1. The specific type of the connecting member is not limited in this embodiment and the accompanying drawings.
[0030] In other embodiments, multiple clips can be provided on the side wall of the first outer part 2, and multiple snap grooves can be provided on the side wall of the second outer part 3 accordingly. Each clip on the first outer part 2 can be snapped into the corresponding snap groove on the second outer part 3, thereby locking the sealing gasket 1 between the first outer part 2 and the second outer part 3.
[0031] Optionally, the first thermal insulation groove 11 is annular, and the center line of the first thermal insulation groove 11 coincides with the center line of the sealing gasket 1. In this way, the first thermal insulation groove 11 and the sealing gasket 1 are concentrically arranged, and uniform thermal insulation is achieved throughout the sealing gasket 1.
[0032] Optionally, the sealing gasket 1 is provided with a plurality of first thermal insulation grooves 11, the centerlines of which coincide with each other, and all of which are located on the first contact surface 14 or the second contact surface 15. Some of the first thermal insulation grooves 11 are located outside the plurality of mounting holes 13, while others are located inside the plurality of mounting holes 13. This arrangement further reduces the contact area between the sealing gasket 1 and the first outer member 2 and / or the second outer member 3, increases the thermal insulation medium between the first outer member 2 and the second outer member 3, and enhances the thermal insulation effect.
[0033] Optionally, the first contact surface 14 and the second contact surface 15 of the sealing gasket 1 are both provided with a plurality of first insulation grooves 11. In this way, first insulation grooves 11 are provided between the sealing gasket 1 and the first outer member 2 and between the sealing gasket 1 and the second outer member 3, further enhancing the insulation effect.
[0034] In this embodiment, the sealing gasket 1 is oval-shaped. The shape of the sealing gasket 1 is identical to that of the first outer member 2 and the second outer member 3. The sealing gasket 1 is connected between the first outer member 2 and the second outer member 3, isolating the first outer member 2 and the second outer member 3 from direct contact, thereby preventing heat transfer between the first outer member 2 and the second outer member 3. In other embodiments, the sealing gasket 1 can be configured in other shapes based on the shapes of the first outer member 2 and / or the second outer member 3 to match the shapes of the first outer member 2 and / or the second outer member 3.
[0035] Optionally, the sealing gasket 1 further includes a second heat-insulating groove 12 disposed between two adjacent mounting holes 13. The second heat-insulating groove 12 is in an elongated strip shape. This arrangement further reduces the contact area between the sealing gasket 1 and the first outer member 2 and the second outer member 3, thereby enhancing the heat-insulating effect.
[0036] It should be understood that the specific number, size and arrangement of the first insulation grooves 11 and the second insulation grooves 12 can be set according to the actual situation of the sealing gasket 1. This embodiment and the accompanying drawings are only examples of the arrangement of the first insulation grooves 11 and the second insulation grooves 12.
[0037] Please refer to Figure 2 On the other hand, this embodiment provides a heat insulation structure, which includes a first outer member 2, a second outer member 3, and the above-mentioned sealing gasket 1. The sealing gasket 1 is connected between the first outer member 2 and the second outer member 3, and at least one of the first outer member 2 and the second outer member 3 can generate heat. In this configuration, the sealing gasket 1 is arranged between the first outer member 2 and the second outer member 3, thereby blocking the heat transfer between the first outer member 2 and the second outer member 3, and preventing the heat generated by the first outer member 2 and the second outer member 3 from affecting each other and interfering with the operation of the device. At the same time, the sealing gasket 1 seals the first outer member 2 and the second outer member 3, preventing the water vapor generated by heating from condensing and entering the interior of the outer member through the gap between the first outer member 2 and the second outer member 3, thereby causing damage to the outer member, and preventing the external environment of the first outer member 2 and the second outer member 3 from interfering with them.
[0038] Optionally, the first external component 2 is a heater control box, and the second external component 3 is a compressor control box. With this arrangement, the heat generated by the heater is blocked by the sealing gasket 1 after being transferred to the heater control box, and is not transferred to the compressor control box. This reduces the impact of the heater heating on the compressor temperature, ensuring the compressor's suction and exhaust performance.
[0039] In another aspect, this embodiment provides a vehicle equipped with an air conditioner including the aforementioned thermal insulation structure. Specifically, the vehicle is a new energy vehicle. Using an air conditioner with this thermal insulation structure prevents the impact of heater heating on the compressor side temperature, ensuring the compressor's intake and exhaust performance, thereby maintaining the air conditioner's heating effect. Furthermore, the air conditioner's control box is hermetically connected to the compressor control box, preventing condensed water from entering the equipment and causing malfunctions.
[0040] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
