Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of battery sealing rings for new energy vehicles, and particularly relates to a sealing ring for a battery of a new energy vehicle. Background Technique
[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels and adopt new in-vehicle power devices), integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.
[0003] Most new energy vehicles are powered by batteries, and the batteries are installed at the bottom of the new energy vehicle. Due to the low installation position, sealing rings are required to seal the periphery of the batteries used in new energy vehicles to prevent water from entering the vehicle interior from the chassis of the new energy vehicle and coming into contact with the batteries, ensuring the safe use of the batteries inside the new energy vehicle.
[0004] However, the existing sealing rings are made of rubber with fixed dimensions and rely on their own elasticity to seal the grooves. There may be gaps between the sealing rings and the inner walls of the grooves, resulting in poor sealing ring effects. Therefore, they do not meet the existing requirements, and for this reason, we propose a sealing ring for a battery of a new energy vehicle. Content of the Utility Model
[0005] The purpose of the utility model is to provide a sealing ring for a battery of a new energy vehicle to solve the problems mentioned in the above background technique, such as the sealing ring being made of rubber with fixed dimensions, relying on its own elasticity to seal the grooves, and there may be gaps between the sealing ring and the inner wall of the groove, resulting in poor sealing ring effects.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A sealing ring for a battery of a new energy vehicle, including a sealing outer ring. An inner side of the sealing outer ring is provided with a U-shaped groove, and an internally reinforced metal lining is clamped in the U-shaped groove. An inner surface of the internally reinforced metal lining is provided with a plurality of docking slots, and an internally supported plate is slidably installed inside the internally reinforced metal lining. The internally supported plate is in an inverted U shape and its side edges are slidably clamped inside the docking slots.
[0007] Preferably, an inner surface of the internally supported plate is provided with a plurality of positioning slots, and two vertically adjacent elastic support plates are installed inside the internally supported plate.
[0008] Preferably, two sides of the elastic support plate are bent downward, the elastic support plate is in an inverted V-shaped structure, and two sides of the elastic support plate are clamped inside the positioning slots.
[0009] Preferably, a filling inner ring is detachably installed on the inner side of the sealing outer ring. A plurality of weight reduction grooves are provided on the bottom surface of the filling inner ring, and the filling inner ring covers the internal support plate through the weight reduction grooves.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0011] 1. The present utility model uses an internal reinforcement metal lining to support the sealing outer ring inside the sealing outer ring, ensuring the stability of the shape of the sealing outer ring, so that the outer surface of the sealing outer ring fits with the inner wall of the installation groove, and the sealing outer ring will not collapse inward. An inverted V-shaped elastic support plate layer is installed inside the internal support plate, and the internal support plate squeezes outward on both sides of the internal support plate, so that the internal support plate applies pressure to the internal reinforcement metal lining and the sealing outer ring outward, ensuring that the outer surface of the sealing outer ring is tightly fitted with the installation groove without gaps, ensuring the overall sealing linearity of the sealing ring, and can be adapted to installation and use in grooves of different widths.

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0017] As Figures 1 to 3 shown, a sealing ring for a new energy vehicle battery, a U-shaped groove is provided on the inner side of the sealing outer ring 1, an internal reinforcement metal lining 3 is clamped in the U-shaped groove, a plurality of docking card slots 4 are provided on the inner surface of the internal reinforcement metal lining 3, an internal support plate 5 is slidably installed inside the internal reinforcement metal lining 3, the internal support plate 5 is in an inverted U shape and the side edges are slidably clamped inside the docking card slots 4. The internal reinforcement metal lining 3 is used to support the sealing outer ring 1 inside the sealing outer ring 1, ensuring the stability of the shape of the sealing outer ring 1, so that the outer surface of the sealing outer ring 1 fits with the inner wall of the installation groove, and the sealing outer ring 1 will not collapse inward.
[0018] The inner surface of the inner support plate 5 is provided with a plurality of positioning grooves 7. Two vertically adjacent elastic support plates 6 are installed inside the inner support plate 5. The two sides of the elastic support plate 6 are bent downward, and the elastic support plate 6 has an inverted V-shaped structure. The two sides of the elastic support plate 6 are clamped inside the positioning groove 7. By using the elastic support plate 6 to squeeze the side of the inner support plate 5 downward inside the inner support plate 5, the inner support plate 5 squeezes the inner reinforcing metal lining 3 and the sealing outer ring 1 outward from the sealing outer ring 1, ensuring that the outer surface of the sealing outer ring 1 fits the inner surface of the installation groove, and there is no gap between the sealing outer ring 1 and the installation groove.
[0019] The inner side of the sealing outer ring 1 is also detachably installed with a filling inner ring 2. The bottom surface of the filling inner ring 2 is provided with a plurality of weight-reducing grooves 8. The filling inner ring 2 covers the inner support plate 5 through the weight-reducing grooves 8. The filling inner ring 2 is used to fill and seal the inner space of the sealing outer ring 1, increasing the stability of the internal structure of the sealing outer ring 1 and ensuring the sealing performance between the upper surface of the sealing outer ring 1 and the contact component.
[0020] Working principle: First, install the sealing outer ring 1 in the groove that needs to be sealed around the battery. Then, slide the inner reinforcing metal lining 3 into the inside of the sealing outer ring 1. Subsequently, squeeze the two sides of the elastic support plate 6 towards the middle to make the elastic support plate 6 bend and deform, and place the deformed elastic support plate 6 into the inner support plate 5, so that the side of the elastic support plate 6 is clamped inside the positioning groove 7. Next, squeeze the two sides of the inner support plate 5 towards the middle, place the squeezed inner support plate 5 inside the inner reinforcing metal lining 3 and ensure that the side of the inner support plate 5 is clamped in the docking slot 4. Release the inner support plate 5 to make the elastic support plate 6 elastically recover. The elastic support plate 6 exerts a force on the inner support plate 5 pointing towards the inner reinforcing metal lining 3. At this time, the side of the inner support plate 5 squeezes the inner reinforcing metal lining 3 and the sealing outer ring 1 outward from the sealing outer ring 1, making the sealing outer ring 1 closely fit the inner surface of the installation groove. At this time, there is no gap between the sealing outer ring 1 and the inner surface of the installation groove. Finally, fill the filling inner ring 2 inside the sealing outer ring 1 and cover the inner support plate 5, ensuring the overall sealing linearity of the sealing ring and enabling it to be installed and used in grooves of different widths.
[0021] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
