Description

Technical Field

[0001] The utility model relates to the field of spring washers for vehicle air conditioners, in particular to a fastening and sealing spring washer for vehicle air conditioners. Background Technique

[0002] The fastening and sealing spring washer for vehicle air conditioners is an indispensable small part in the automotive air conditioning system. Its main function is to play a key role in fixing and sealing each component during the assembly and maintenance of the air conditioning system. The design and material of these spring washers are to ensure the firm and reliable connection between each component in the air conditioning system, and at the same time achieve a complete sealing effect, thereby effectively preventing the leakage of refrigerant.

[0003] Traditional sealing spring washers usually do not have effective shock absorption measures. During vehicle driving, especially when the road conditions are poor or the vehicle is driving at high speed, the spring washers are prone to damage due to continuous vibration and impact. This kind of damage will not only accelerate the aging of the spring washers, but may also cause the loosening of the connecting components, further weakening the sealing performance, and even may lead to the failure of the entire air conditioning system, affecting the comfort and safety of the vehicle.

[0004] Therefore, those skilled in the art provide a fastening and sealing spring washer for vehicle air conditioners to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the content of the utility model is to solve the deficiencies existing in the prior art, and to propose a fastening and sealing spring washer for vehicle air conditioners. By arranging an airbag in the second through groove at the lower part of the sealing ring and using air pressure to generate an outward expansion on the sealing ring, the sealing performance of the sealing spring washer is further improved, and the service life of the sealing spring washer is increased.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A fastening and sealing spring washer for vehicle air conditioners includes a sealing mechanism. The sealing mechanism includes a first elastic pad and a second elastic pad. The upper end of the first elastic pad is fixedly connected with a lower backing plate. The lower end of the second elastic pad is fixedly connected with an upper backing plate. The upper end of the lower backing plate is fixedly connected with a sealing ring. The upper end of the sealing ring is fixedly connected with the lower end of the upper backing plate. Through holes are formed in the middle parts of the first elastic pad, the second elastic pad, the lower backing plate, the upper backing plate and the sealing ring.

[0008] Through the above technical solution, by arranging an airbag in the second through groove at the lower part of the sealing ring and using air pressure to generate an outward expansion on the sealing ring, the sealing performance of the sealing spring washer is further improved, and the service life of the sealing spring washer is increased.

[0009] Furthermore, both the upper backing plate and the lower backing plate are made of aluminum alloy;

[0010] Through the above technical solution, the aluminum alloy has good heat conduction performance, which helps to quickly conduct the heat generated by the air-conditioning system, reduce the risk of local overheating, and maintain the uniformity of the system temperature.

[0011] Furthermore, the first elastic pad, the second elastic pad and the sealing ring are all made of rubber material;

[0012] Through the above technical solution, the rubber material can well fit the sealing surface, prevent gas or liquid leakage, ensure the normal operation of the air-conditioning system, and the rubber material has excellent shock absorption performance, which helps to absorb and reduce the vibration generated during vehicle operation, and protect other components of the air-conditioning system from damage.

[0013] Furthermore, a spacer is fixedly connected to the middle of the sealing ring;

[0014] Through the above technical solution, the spacer can protect the sealing surface from direct contact and wear. Especially in the case where the sealing surface is relatively sensitive or easy to be damaged, the fixed connection of the spacer can improve the stability of the sealing ring and prevent the displacement of the sealing ring during vibration or impact.

[0015] Furthermore, a second through groove is opened at the lower end of the sealing ring, and an airbag is arranged inside the second through groove;

[0016] Through the above technical solution, the airbag can dynamically adjust its internal air pressure according to the actual condition of the sealing surface, so as to adapt to different sealing requirements and provide a more accurate and reliable sealing effect. After being inflated, the airbag can generate an outward expanding force on the sealing ring, making the sealing ring fit more closely on the sealing surface and effectively preventing medium leakage.

[0017] Furthermore, a first through groove is opened at the upper end of the sealing ring, and a plurality of springs are arranged inside the first through groove;

[0018] Through the above technical solution, the springs can evenly disperse the pressure received at the upper end of the sealing ring, reduce local stress concentration, and thus extend the service life of the sealing ring.

[0019] Furthermore, the upper ends of the springs are fixedly connected to the lower end of the upper backing plate, and the lower ends of the springs are fixedly connected to the upper end of the spacer;

[0020] Through the above technical solution, by fixing the upper ends of the springs to the lower end of the upper backing plate and the lower ends to the upper end of the spacer, a stable support structure is formed, which helps to maintain the stability of the entire sealing system. As an elastic element, the springs can effectively transmit the pressure of the upper backing plate to the spacer, and then to the sealing ring by the spacer, so as to maintain the close contact between the sealing ring and the sealing surface.

[0021] The utility model has the following beneficial effects:

[0022] 1. A vehicle air conditioner fastening and sealing elastic gasket proposed by the present utility model improves the sealing performance of the elastic gasket and extends its service life by arranging an airbag in the second through groove at the lower part of the sealing ring, and using air pressure to expand the sealing ring outward.

[0023] 2. A vehicle air conditioner fastening and sealing elastic gasket proposed by the present utility model is provided with an upper backing plate and a lower backing plate, and springs are arranged inside the first through groove at the upper part of the lower backing plate and the sealing ring.

[0030] The technical solutions in the specific embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the specific embodiments of the present utility model. Obviously, the described specific embodiments are only a part of the specific embodiments of the present utility model, rather than all of them. All other specific embodiments obtained by those of ordinary skill in the art based on the specific embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figure 1 、 Figure 2 and Figure 3 a specific embodiment provided by the present utility model is as follows:

[0032] A fastening and sealing spring washer for a vehicle air conditioner, comprising a sealing mechanism 1. The sealing mechanism 1 includes a first elastic pad 101 and a second elastic pad 102. The upper end of the first elastic pad 101 is fixedly connected to a lower backing plate 103. The lower end of the second elastic pad 102 is fixedly connected to an upper backing plate 104. The upper end of the lower backing plate 103 is fixedly connected to a sealing ring 110. The upper end of the sealing ring 110 is fixedly connected to the lower end of the upper backing plate 104. Through holes 111 are provided in the middles of the first elastic pad 101, the second elastic pad 102, the lower backing plate 103, the upper backing plate 104 and the sealing ring 110.

[0033] By arranging an airbag 108 in a second through groove 109 below the sealing ring 110, the air pressure is used to generate an outward expansion on the sealing ring 110, further improving the sealing performance of the sealing spring washer and increasing the service life of the sealing spring washer.

[0034] Refer to Figure 2 、 Figure 3 and Figure 4, both the upper backing plate 104 and the lower backing plate 103 are made of aluminum alloy. Aluminum alloy has good heat conduction performance, which helps to quickly conduct the heat generated by the air-conditioning system, reduce the risk of local overheating, maintain the uniformity of the system temperature. The first elastic pad 101, the second elastic pad 102 and the sealing ring 110 are all made of rubber material. Rubber material can well fit the sealing surface, prevent gas or liquid leakage, and ensure the normal operation of the air-conditioning system. The rubber material has excellent shock absorption performance, which helps to absorb and reduce the vibration generated during vehicle operation, and protect other components of the air-conditioning system from damage. A spacer 107 is fixedly connected to the middle of the sealing ring 110. The spacer 107 can protect the sealing surface from direct contact and wear, especially when the sealing surface is relatively sensitive or easy to be damaged. The fixed connection of the spacer 107 can improve the stability of the sealing ring 110 and prevent the displacement of the sealing ring 110 during vibration or impact. A second through groove 109 is opened at the lower end of the sealing ring 110, and an airbag 108 is arranged inside the second through groove 109. The airbag 108 can dynamically adjust its internal air pressure according to the actual condition of the sealing surface, so as to adapt to different sealing requirements and provide a more accurate and reliable sealing effect. After being inflated, the airbag 108 can generate an outward expansion force on the sealing ring 110, making the sealing ring 110 fit more tightly on the sealing surface and effectively preventing medium leakage. A first through groove 106 is opened at the upper end of the sealing ring 110, and a plurality of springs 105 are arranged inside the first through groove 106. The springs 105 can evenly disperse the pressure received at the upper end of the sealing ring 110, reduce local stress concentration, and thus extend the service life of the sealing ring 110. The upper ends of the springs 105 are fixedly connected to the lower end of the upper backing plate 104, and the lower ends of the springs 105 are fixedly connected to the upper end of the spacer 107. By fixing the upper ends of the springs 105 to the lower end of the upper backing plate 104 and the lower ends to the upper end of the spacer 107, a stable support structure is formed, which helps to maintain the stability of the entire sealing system. As an elastic element, the spring 105 can effectively transmit the pressure of the upper backing plate 104 to the spacer 107, and then transmit it to the sealing ring 110 through the spacer 107, so as to maintain the close contact between the sealing ring 110 and the sealing surface.

[0035] Working principle: By arranging an airbag 108 in the second through groove 109 at the lower part of the sealing ring 110, the air pressure is used to generate an outward expansion on the sealing ring 110, further improving the sealing performance of the sealing elastic pad and extending the service life of the sealing elastic pad. At the same time, by arranging the upper backing plate 104 and the lower backing plate 103, and arranging springs 105 inside the first through groove 106 at the upper part of the lower backing plate 103 and the sealing ring 110, when the whole sealing elastic pad is vibrated, the elastic force of the springs 105 can offset part of the vibration force, playing a shock absorption role, making the elastic pad not easily damaged and increasing the service life. When the machine generates vibration, the springs 105 can play a shock absorption role and can make the elastic pad always in close contact with the upper and lower parts, not easily falling off.

[0036] Finally, it should be noted that the above are only the preferred specific embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing specific embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
