Abstract
Description
Technical Field
[0001] This application relates to the field of automotive refrigerator technology, and more particularly to a refrigerator sealing strip, an automotive refrigerator, and a vehicle. Background Technology
[0002] A car refrigerator is a portable refrigeration device designed specifically for use inside a vehicle. Powered by the vehicle's power supply, it is used to refrigerate or freeze food, beverages, medicines, and other items while traveling or during outdoor activities. The refrigerator door seal is a flexible rubber or silicone component along the inner edge of the refrigerator door. Its core function is to ensure a tight seal between the door and the refrigerator body when closed, creating a sealed environment. It directly affects the refrigerator's insulation performance, energy consumption, and cooling efficiency. Traditional refrigerator door seals often fail to provide a proper seal, leading to cold air leakage. Utility Model Content
[0003] Based on this, this application provides a refrigerator sealing strip, a vehicle refrigerator, and a vehicle, which can solve the problem of poor sealing of the refrigerator sealing strip.
[0004] In a first aspect, embodiments of this application provide a refrigerator sealing strip, comprising:
[0005] The sealing strip body is annular, and the cross-section of the sealing strip body includes a first layer, a second layer, and a third layer arranged at intervals in sequence.
[0006] The first slot is formed between the inner sides of the first layer and the second layer, and the second slot is formed between the outer sides of the first layer and the second layer.
[0007] The outer sides of the second and third layers are connected by a sealing part, forming a hollow cavity.
[0008] The refrigerator sealing strip according to the embodiments of this application has at least the following beneficial effects: During installation, the first and second slots engage with the lower cover clip of the refrigerator door, ensuring a secure seal. Since the second and third layers are hollow chambers, and only their outer sides are connected by a sealing part, while their inner sides are disconnected, significant compression deformation occurs when the lower surface of the third layer contacts and is compressed against the refrigerator body. This ensures both proper closure and a tight seal. The sealing part isolates the hollow chamber from the outside, preventing cold air from escaping from the refrigerator.
[0009] According to some embodiments of this application, in the hollow cavity, a first groove is provided at the connection position between the sealing part and the second layer, and a second groove is provided at the connection position between the sealing part and the third layer.
[0010] In this embodiment, by setting the first and second inverted grooves, the third layer is more likely to undergo compression deformation and a greater amount of compression deformation when under pressure, thereby improving the sealing effect of the refrigerator and avoiding the situation where the refrigerator door cannot be closed properly due to insufficient force.
[0011] According to some embodiments of this application, the inner side of the third layer is provided with a flange that extends toward the second layer.
[0012] In this embodiment, by providing a flange on the inner side of the third layer, the thickness of the third layer at the flange is relatively thicker, thereby enhancing resistance to aging and deformation, avoiding poor sealing that could lead to cold air leakage in the refrigerator, and improving the service life of the refrigerator sealing strip.
[0013] According to some embodiments of this application, the sealing part is provided with a vent hole, which communicates with the hollow cavity.
[0014] In this embodiment, by providing a vent in the sealing part, the pressure difference between the inside and outside of the refrigerator is balanced, thereby ensuring the normal opening of the refrigerator door.
[0015] According to some embodiments of this application, the third layer is inclined and tilted away from the second layer in the direction from the outside to the inside.
[0016] In this embodiment, by tilting the third layer, when the refrigerator door closes with the refrigerator body, the inner side of the third layer will contact the refrigerator body first, and the inner side of the third layer will have a greater amount of compression deformation, thus achieving a better sealing effect.
[0017] According to some embodiments of this application, the first layer is provided with a connector for fixed connection with the refrigerator door.
[0018] In this embodiment, by providing a connector on the first layer for fixed connection with the refrigerator door, the refrigerator sealing strip is fixedly connected to the refrigerator door through the connector when installed on the refrigerator door. This improves the strength of the connection between the refrigerator sealing strip and the refrigerator door, and also prevents problems such as the refrigerator sealing strip falling off after prolonged use.
[0019] According to some embodiments of this application, the connector includes a limiting portion at the head end and a locking portion at the tail end. The locking portion is perpendicularly connected to the first layer, and the limiting portion is frustum-shaped with a bottom area larger than the cross-sectional area of the locking portion.
[0020] In this embodiment, during installation, the limiting part of the connector passes through the mounting hole of the refrigerator door, and the snap-fit part snaps into the mounting hole. Because the bottom area of the limiting part is larger than the cross-sectional area of the snap-fit part, the limiting part is fixed in the mounting hole, preventing it from falling off. The limiting part is frustum-shaped to ensure that it can pass smoothly through the mounting hole.
[0021] According to some embodiments of this application, there are multiple connectors arranged around the periphery of the sealing strip body.
[0022] In this embodiment, there are multiple connectors arranged around the perimeter of the sealing strip body, which can improve the firmness of the connection between the refrigerator sealing strip and the refrigerator door.
[0023] Secondly, this application also discloses a vehicle refrigerator, including the aforementioned refrigerator sealing strip.
[0024] The vehicle-mounted refrigerator according to the embodiments of this application has at least the following beneficial effects: the vehicle-mounted refrigerator using the refrigerator sealing strip of this application solves the problem of cold air leakage caused by poor sealing of the vehicle-mounted refrigerator. At the same time, it can avoid problems such as the sealing strip falling off after long-term use.
[0025] Thirdly, this application also discloses a vehicle including the aforementioned vehicle-mounted refrigerator.
[0026] The vehicle according to the embodiments of this application has at least the following beneficial effects: The vehicle using the vehicle refrigerator of this application solves the problem of cold air leakage caused by poor sealing of the vehicle refrigerator. At the same time, it can avoid problems such as the sealing strip of the vehicle refrigerator falling off after prolonged use.

[0041] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.
[0042] refer to Figure 1 and Figure 2 As shown, this application discloses a refrigerator sealing strip, comprising:
[0043] The sealing strip body 100 is annular, and the cross-section of the sealing strip body 100 includes a first layer 200, a second layer 300 and a third layer 400 arranged at intervals in sequence.
[0044] The inner sides of the first layer 200 and the second layer 300 form a first slot 500, and the outer sides of the first layer 200 and the second layer 300 form a second slot 600.
[0045] The outer sides of the second layer 300 and the third layer 400 are connected by a sealing part 700, forming a hollow cavity 800.
[0046] The sealing strip body 100 is annular and is used to install on the refrigerator door 1. In this embodiment, the cross-section of the sealing strip body 100 includes a first layer 200, a second layer 300, and a third layer 400 arranged sequentially at intervals. Specifically, in this embodiment, the first layer 200, the second layer 300, and the third layer 400 are arranged sequentially from top to bottom. The first layer 200 and the second layer 300 are connected together in the middle, and the two sides respectively form a first slot 500 and a second slot 600. The outer sides of the second layer 300 and the third layer 400 are connected by a sealing part 700 to form a hollow cavity 800. In this embodiment, the inner and outer sides refer to the areas within the ring of the sealing strip body 100 relative to the sealing strip body 100, and the areas outside the ring of the sealing strip body 100.
[0047] Combination Figure 3 As shown, when the sealing strip body 100 is installed, the first slot 500 and the second slot 600 engage with the lower cover clip 10 of the refrigerator door 1, which can make the refrigerator sealing strip firmly assembled.
[0048] When the refrigerator door 1 closes with the refrigerator body, the lower surface of the third layer 400 will contact the refrigerator body and undergo compression deformation due to the force, thereby completing the sealing of the refrigerator.
[0049] Since the second layer 300 and the third layer 400 are hollow chambers 800, and the second layer 300 and the third layer 400 are only connected by the sealing part 700 on their outer sides, while their inner sides are disconnected, when the lower surface of the third layer 400 contacts the refrigerator body and is subjected to pressure, the third layer 400 will undergo significant compression deformation. This ensures that the refrigerator door closes properly and maintains its airtightness. The sealing part 700 isolates the hollow chamber 800 from the outside, preventing cold air from escaping from the hollow chamber 800.
[0050] refer to Figure 2 As shown, in some embodiments of this application, a first groove 910 is provided at the connection position between the sealing part 700 and the second layer 300 in the hollow cavity 800, and a second groove 920 is provided at the connection position between the sealing part 700 and the third layer 400.
[0051] In this embodiment, by setting the first groove 910 and the second groove 920, the third layer 400 is more prone to compression deformation and a greater amount of compression deformation when under pressure, thereby improving the sealing effect of the refrigerator and preventing the refrigerator door from not closing properly due to insufficient force. The first groove 910 and the second groove 920 can be obtained through a degumming process, and both the first groove 910 and the second groove 920 are arc-shaped grooves.
[0052] refer to Figure 2 As shown, in some embodiments of this application, the inner side of the third layer 400 is provided with a flange 410, which extends toward the second layer 300.
[0053] Refrigerator sealing strips inevitably age over time. Since the inner side of the third 400 layer is suspended, it is prone to sagging and deformation after aging, resulting in a decrease in sealing performance.
[0054] In this embodiment, by providing a flange 410 on the inner side of the third layer 400, the thickness of the third layer 400 at the flange 410 is relatively thicker, thereby enhancing resistance to aging and deformation, preventing poor sealing from causing cold air leakage in the refrigerator, and improving the service life of the refrigerator sealing strip. Furthermore, the flange 410 extends towards the second layer 300, preventing the inner side of the third layer 400 from flanging downwards due to aging.
[0055] refer to Figure 4 As shown, in some embodiments of this application, the sealing part 700 is provided with a vent 710, which communicates with the hollow cavity 800.
[0056] When a refrigerator is in cooling mode, the gas inside the refrigerator is pre-cooled and contracts, resulting in low internal air pressure and high external air pressure. If the internal and external gases are not connected, the large pressure difference between the inside and outside of the refrigerator may cause the refrigerator door to be difficult to open or even impossible to open.
[0057] In this embodiment, to avoid the problem of a large pressure difference between the inside and outside of the refrigerator, making it difficult to open the refrigerator door in cooling mode, a vent 710 is provided in the sealing part 700 to balance the pressure difference between the inside and outside of the refrigerator, thereby ensuring the normal opening of the refrigerator door. At the same time, since the vent 710 causes the loss of cold air, the diameter of the vent 710 needs to be controlled to avoid excessive cold air flow and resulting in power consumption loss. Furthermore, to prevent foreign objects from entering the refrigerator through the vent 710 and to avoid the vent 710 affecting the aesthetics of the refrigerator, the vent 710 is preferably located at the rear end of the refrigerator door.
[0058] refer to Figure 3 As shown, in some embodiments of this application, the third layer 400 is inclined and tilted away from the second layer 300 in the direction from the outside to the inside.
[0059] In this embodiment, by tilting the third layer 400, when the refrigerator door 1 closes with the refrigerator body, the inner side of the third layer 400 will contact the refrigerator body first, and the inner side of the third layer 400 will have a greater amount of compression deformation, thus achieving a better sealing effect.
[0060] refer to Figure 1As shown, in some embodiments of this application, the first layer 200 is provided with a connector 310 for fixed connection with the refrigerator door.
[0061] Over time, refrigerator door seals lose elasticity due to aging, making them prone to detachment if held in place solely by their natural elasticity. To improve the secure fit between the seal and the door, a connector 310 is provided on the first layer 200 for fixed connection. When the seal is installed on the door, it is secured using the connector 310, enhancing the connection and preventing detachment over time. In this embodiment, the connector 310 can be a snap-fit, pin, or other similar fastener.
[0062] refer to Figure 5 and Figure 6 As shown, in some embodiments of this application, the connector 310 includes a limiting part 312 at the head end and a locking part 311 at the tail end. The locking part 311 is vertically connected to the first layer 200. The limiting part 312 is frustum-shaped, and the bottom area of the limiting part 312 is larger than the cross-sectional area of the locking part 311.
[0063] In this embodiment, during installation, the limiting part 312 of the connector 310 passes through the mounting hole of the refrigerator door 1, and the snap-fit part 311 snaps into the mounting hole. Because the bottom area of the limiting part 312 is larger than the cross-sectional area of the snap-fit part 311, the limiting part 312 is fixed in the mounting hole, preventing it from falling off. The limiting part 312 is frustum-shaped, ensuring that it can pass smoothly through the mounting hole. Specifically, the connector 310 is a mushroom-shaped pin. The connector 310 and the mounting hole are interference-fitted, which effectively ensures a firm and reliable installation and prevents it from falling off over a long period of time.
[0064] refer to Figure 1 As shown, in some embodiments of this application, there are multiple connectors 310, and multiple connectors 310 are arranged around the sealing strip body 100.
[0065] In this embodiment, there are multiple connectors 310, which are arranged around the perimeter of the sealing strip body to improve the firmness of the connection between the refrigerator sealing strip and the refrigerator door. Specifically, there are eight connectors 310.
[0066] This application also discloses a vehicle refrigerator, including the aforementioned refrigerator sealing strip.
[0067] This application also discloses a vehicle including the aforementioned vehicle-mounted refrigerator.
[0068] Since the vehicle refrigerator and vehicle of this application adopt all the technical solutions of the refrigerator sealing strip of the above embodiments, they have at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 application.
