[0002] In the manufacturing process of electric vehicle battery cells, sealing and waterproofing the cell modules is a crucial step. Water ingress into the cell modules can lead to cell and electronic component failure, affecting the overall quality of the module. Current electric vehicle battery cell manufacturing processes utilize sealed waterproof enclosures to seal and waterproof the cell modules.

[0003] Existing aluminum-magnesium alloy enclosures for sealing and waterproofing electric vehicle battery modules consist of a cover and a body. A sealing ring is placed on the contact surface between the cover and the body, and the cover and body are tightly connected by bolts to achieve a sealing and waterproofing effect. However, during vehicle operation, there is vibration, and long-term use can cause the connecting bolts to loosen, resulting in gaps between the cover and the body, which reduces the waterproofing performance and makes it impractical. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an aluminum-magnesium alloy box that can effectively improve the sealing performance between the box lid and the box body, avoid gaps between the box lid and the box body, maintain good sealing and waterproof performance, and improve practicality.

The connecting assembly includes a positioning platform fixedly connected to the bottom of the cover, a U-shaped sealing platform fixedly connected to the top of the enclosure body, a sealing gasket fixedly connected to the top of the U-shaped sealing platform, multiple sets of countersunk holes formed around the top of the cover, each set of countersunk holes containing an internal hexagon countersunk bolt, and multiple sets of threaded holes formed on the top four sets of the U-shaped sealing platform. The cover is fitted by the mating of the internal hexagon countersunk bolts with the threaded holes. On the U-shaped sealing platform, the positioning platform is in contact with the inner wall of the box around its perimeter. The clamping assembly includes a pressure plate and two sets of guide sleeves. A V-shaped clamping plate is fixedly provided at the bottom end of the pressure plate, and two sets of T-shaped guide rods are fixedly connected to the bottom end of the pressure plate. The two sets of T-shaped guide rods are symmetrically distributed on the front and rear sides of the V-shaped clamping plate. The two sets of guide sleeves are symmetrically rotatably connected to the front and rear ends of the U-shaped sealing platform. The two sets of T-shaped guide rods are slidably installed on the two sets of guide sleeves respectively. A spring is fitted on each of the two sets of T-shaped guide rods. The two ends of the springs are fixedly connected to the bottom of the inner side of the guide sleeves and the T-shaped guide rods respectively. Two sets of V-shaped slots are symmetrically fixed at the top of the box cover. The two sets of V-shaped clamping plates are respectively clamped and pressed on the two sets of V-shaped slots under the action of the springs.

[0007] Preferably, both sets of pressure plates are fixedly connected to a carrying handle at their top ends.

[0008] Preferably, both sets of handles are fixedly fitted with anti-slip handle sleeves.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the box cover is placed on the U-shaped sealing platform by connecting the internal hexagon countersunk bolt to the threaded hole. During installation, the countersunk hole and threaded hole are aligned through the cooperation of the positioning platform and the inner wall of the box. Then, the internal hexagon countersunk bolt is screwed into the threaded hole, and the head of the internal hexagon countersunk bolt is recessed into the countersunk hole. This makes the top surface of the box cover flat, and the sealing gasket is pressed tightly by the box cover and the U-shaped sealing platform, achieving a sealing effect. Furthermore, the cooperation between the internal hexagon countersunk bolt and the countersunk hole provides greater... The tightening force makes the connection between the lid and the U-shaped sealing platform more secure, making it less likely for the internal hexagon countersunk bolts to loosen. By pressing the pressure plate onto the V-shaped groove, the spring is in a compressed state, thus providing downward pressure on the lid. When the internal hexagon countersunk bolts loosen due to vibration, the lid, under the spring force and the downward pressure of the pressure plate, maintains a tight seal with the U-shaped sealing platform, thereby keeping the box body sealed. This effectively improves the sealing performance between the lid and the box body, avoids gaps between the lid and the box body, maintains good sealing and waterproof performance, and improves practicality.

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0018] Example

[0019] Please see Figures 1-5 This utility model discloses an aluminum-magnesium alloy enclosure, comprising an enclosure 1, a cover 2 mounted on the top of the enclosure 1, a connecting assembly disposed between the cover 2 and the enclosure 1, and two sets of clamping assemblies symmetrically disposed on the enclosure 1 and the cover 2. The connecting assembly includes a positioning platform 3 fixedly connected to the bottom of the cover 2, a U-shaped sealing platform 4 fixedly connected to the top of the enclosure 1, a sealing gasket 17 fixedly connected to the top of the U-shaped sealing platform 4, multiple sets of countersunk holes 5 formed around the top of the cover 2, each set of countersunk holes 5 containing an internal hexagon countersunk bolt 6, and multiple sets of threaded holes 7 formed in four sets at the top of the U-shaped sealing platform 4. The cover 2 is connected to the cover 2 by the internal hexagon countersunk bolts 6. The mating cover of the threaded hole 7 is mounted on the U-shaped sealing platform 4. The positioning platform 3 is in contact with the inner wall of the box 1 around its perimeter. The clamping assembly includes a pressure plate 8 and two sets of guide sleeves 11. A V-shaped clamping plate 9 is fixedly provided at the bottom end of the pressure plate 8. Two sets of T-shaped guide rods 10 are fixedly connected to the bottom end of the pressure plate 8. The two sets of T-shaped guide rods 10 are symmetrically distributed on the front and rear sides of the V-shaped clamping plate 9. The two sets of guide sleeves 11 are symmetrically rotatably connected to the front and rear ends of the U-shaped sealing platform 4. The two sets of T-shaped guide rods 10 are slidably mounted on the two sets of guide sleeves 11 respectively. A spring 12 is fitted on each of the two sets of T-shaped guide rods 10. The two ends of the spring 12 are fixedly connected to the bottom inner side of the guide sleeve 11 and the T-shaped guide rod 10 respectively. Two sets of V-shaped grooves 13 are symmetrically fixed at the top of the cover 2. Two sets of V-shaped clamping plates 9 are respectively clamped onto the two sets of V-shaped grooves 13 under the action of springs 12. In use, the cover 2 is placed onto the U-shaped sealing platform 4 by connecting the internal hexagon countersunk bolt 6 to the threaded hole 7. During installation, the countersunk hole 5 is aligned with the threaded hole 7 by the cooperation between the positioning platform 3 and the inner wall of the box body 1. Then, the internal hexagon countersunk bolt 6 is screwed into the threaded hole 7, and the head of the internal hexagon countersunk bolt 6 is recessed into the countersunk hole 5. This makes the top surface of the cover 2 flat, and the sealing gasket 17 is pressed tightly by the cover 2 and the U-shaped sealing platform 4, achieving a sealing effect. Furthermore, the internal hexagon countersunk bolt... The engagement of the head bolt 6 with the countersunk hole 5 provides greater tightening force, making the connection between the cover 2 and the U-shaped sealing platform 4 more secure and preventing the internal hexagon countersunk bolt 6 from loosening. By pressing the pressure plate 8 onto the V-shaped groove 13, the spring 12 is in a compressed state, thus providing downward pressure on the cover 2. When the internal hexagon countersunk bolt 6 loosens due to vibration, the cover 2, under the elastic force of the spring 12 and the downward pressure of the pressure plate 8, maintains a sealed fit with the U-shaped sealing platform 4, thereby keeping the box body sealed. This effectively improves the sealing performance between the cover and the box body, avoids gaps between the cover and the box body, maintains good sealing and waterproof performance, and improves practicality.

[0020] Both sets of pressure plates 8 are fixedly connected to a handle 14 at their top ends; by setting the handle 14, the pressure plates 8 can be pulled more conveniently.

[0021] Both sets of handles 14 are fixedly fitted with anti-slip handle sleeves 15; by setting the anti-slip handle sleeves 15, when the hand holds the handle 14 and pulls the pressure plate 8, the hand is prevented from slipping and falling out.

[0022] Each of the four guide sleeves 11 has a sliding sleeve 16 fixedly installed on its inner wall; by installing the sliding sleeve 16, the T-shaped guide rod 10 can slide more smoothly on the guide sleeve 11.

[0023] This utility model discloses an aluminum-magnesium alloy enclosure. Its working principle is as follows: Initially, rotating the guide sleeve 11 positions the two sets of pressure plates 8 on the left and right sides of the enclosure 1. After the battery is installed inside the enclosure 1, the enclosure cover 2 is placed on the U-shaped sealing platform 4. Through the cooperation of the positioning platform 3 and the inner wall of the enclosure 1, the countersunk hole 5 and the threaded hole 7 are quickly aligned. Then, the hexagonal countersunk bolt 6 is screwed into the threaded hole 7, and the head of the hexagonal countersunk bolt 6 is recessed into the countersunk hole 5. This makes the top surface of the enclosure cover 2 flat, and the sealing gasket 17 is pressed tightly by the enclosure cover 2 and the U-shaped sealing platform 4, achieving a sealing effect. Furthermore, the cooperation between the hexagonal countersunk bolt 6 and the countersunk hole 5 provides greater tightening force, making the connection between the enclosure cover 2 and the U-shaped sealing platform 4 more secure. To prevent the countersunk head bolt 6 from loosening, after the cover 2 is connected, the pressure plate 8 pulls the T-shaped guide rod 10 to slide, compressing the spring 12 and rotating the pressure plate 8 above the cover 2. Then, the pressure plate 8 is released, and the spring 12 begins to rebound. Through the rebound of the spring 12, the pressure plate 8 is pressed onto the V-shaped groove 13 with the cooperation of the V-shaped clamping plate 9. By pressing the pressure plate 8 onto the V-shaped groove 13, downward pressure is applied to the cover 2. Through the cooperation of the V-shaped clamping plate 9 and the V-shaped groove 13, the pressure plate 8 is limited, preventing it from shifting left or right. If the countersunk head bolt 6 loosens due to vibration, the cover 2 remains sealed to the U-shaped sealing platform 4 under the elastic force of the spring 12 and the downward pressure of the pressure plate 8, keeping the box sealed.

[0024] The aluminum-magnesium alloy enclosure of this utility model uses common mechanical methods for installation, connection, or setting. Any method that can achieve the desired beneficial effect can be implemented. The internal hexagon countersunk head bolts of the aluminum-magnesium alloy enclosure of this utility model are commercially available. Technical personnel in this industry only need to follow the accompanying instruction manual for installation and operation.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
