Description

Technical Field

[0001] This utility model relates to the field of battery pack housing technology, and in particular to a high-strength battery pack housing. Background Technology

[0002] The battery pack casing of a new energy vehicle is the main carrier of its internal components. Many components in the battery pack system are installed on the internal structure of the battery pack casing in various ways. The battery pack casing is an outer casing that carries the battery cells.

[0003] Existing battery pack casings are not strong enough during use. Most are made of aluminum alloy, which is not strong enough. When the battery pack is placed inside the casing, if the casing is not strong enough, it can easily be damaged by an impact, which will directly lead to damage to the battery pack inside. Therefore, those skilled in the art have provided a high-strength battery pack casing to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a high-strength battery pack shell that has a certain strength during use and can better protect the battery pack inside.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-strength battery pack housing includes a housing and a sealing cover. The housing has a U-shaped cavity inside, and a U-shaped reinforcing plate is provided inside the cavity. Several strong springs are fixedly connected to the outer surface of the reinforcing plate, and the end of each strong spring away from the reinforcing plate is fixedly connected to the inner wall of the cavity.

[0007] The bottom surface of the sealing cover is in contact with the upper surface of the housing. Two bearings are fixedly embedded in the inner wall of the sealing cover. The inner rings of the two bearings are fixedly connected to a positive and negative threaded screw. The outer surface of the positive and negative threaded screw is threaded with two sliding plates. The bottom surface of the sealing cover has a sliding opening. The bottom end of each sliding plate passes through the sliding opening and is fixedly connected to a fixing plate. Each sliding plate is slidably connected inside the sliding opening.

[0008] Preferably, a first nut is fixedly connected to both the left and right sides of the sealing cover, and a second nut is fixedly connected to the upper part of both the left and right sides of the housing. A bolt is provided above each first nut, and the bottom end of each bolt passes through the first nut and the second nut in sequence and extends to the bottom of the second nut.

[0009] Preferably, the upper surface of the housing has two stabilizing openings, and the bottom surface of the sealing cover is fixedly connected to two stabilizing blocks that are adapted to the stabilizing openings, with the bottom end of each stabilizing block extending into the interior of the stabilizing opening.

[0010] Preferably, the upper surface of the sealing cover is provided with an adjustment port, and a protective sleeve is fixedly connected to the middle of the outer surface of the positive and negative threaded screw.

[0011] Preferably, a waterproof membrane is fixedly connected to the inner wall of the housing, an anti-slip pad is fixedly connected to the inner bottom wall of the housing, and protective pads are fixedly connected to the sides of the two fixing plates that are close to each other.

[0012] The beneficial effects of this utility model are as follows: The housing allows for the installation of a battery pack. The reinforcing plate, combined with a strong spring, directly increases the strength of the housing. The strong spring also acts as a buffer, cushioning the impact force received by the housing. The presence of positive and negative threaded screws allows two sliding plates to move closer together, which in turn moves the fixing plates closer together. This close proximity of the fixing plates secures the battery pack inside the housing, protecting it within the reinforcing plate. This effectively solves the problem of insufficient housing strength currently used for battery packs, which fails to adequately protect the battery pack. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please refer to the reference. Figures 1-3 A high-strength battery pack casing includes a casing 1 and a sealing cover 11. The casing 1 has a U-shaped cavity 6 inside, and a U-shaped reinforcing plate 4 is provided inside the cavity 6. Several strong springs 5 ​​are fixedly connected to the outer surface of the reinforcing plate 4. The end of each strong spring 5 away from the reinforcing plate 4 is fixedly connected to the inner wall of the cavity 6. A waterproof membrane 2 is fixedly connected to the inner wall of the casing 1, and an anti-slip pad 3 is fixedly connected to the inner bottom wall of the casing 1. The waterproof membrane 2 serves the purpose of waterproofing, and the anti-slip pad 3 serves the purpose of preventing slippage of the battery pack.

[0019] The bottom surface of the sealing cover 11 is in contact with the upper surface of the housing 1. The left and right sides of the sealing cover 11 are fixedly connected with first nuts 14, and the upper parts of the left and right sides of the housing 1 are fixedly connected with second nuts 7. Each first nut 14 is provided with a bolt 8 above it. The bottom end of each bolt 8 passes through the first nut 14 and the second nut 7 in sequence and extends to the bottom of the second nut 7. By providing the first nuts 14, the second nuts 7 and the bolts 8, it is easy to connect the sealing cover 11 with the housing 1, which increases the fixation and can better protect the battery pack.

[0020] Two stabilizing openings 13 are provided on the upper surface of the housing 1. Two stabilizing blocks 9 that are adapted to the stabilizing openings 13 are fixedly connected to the bottom surface of the sealing cover 11. The bottom end of each stabilizing block 9 extends into the interior of the stabilizing opening 13. Through the cooperation between the stabilizing openings 13 and the stabilizing blocks 9, the stability of the sealing cover 11 above the housing 1 is increased, avoiding the problem of shaking or falling off.

[0021] Two bearings 15 are fixedly embedded in the inner wall of the sealing cover 11. The inner rings of the two bearings 15 are fixedly connected to a positive and negative threaded screw 17. The outer surface of the positive and negative threaded screw 17 is threaded with two sliding plates 20. The bottom surface of the sealing cover 11 has a sliding opening 16. The bottom end of each sliding plate 20 passes through the sliding opening 16 and is fixedly connected to a fixing plate 10. The two fixing plates 10 are fixedly connected to a protective pad 12 on their adjacent sides. By setting the protective pad 12, the purpose of protection is achieved, which increases the safety of the battery pack during the fixing process and avoids the problem of surface damage.

[0022] Each slide plate 20 is slidably connected inside the slide opening 16. An adjustment port 19 is provided on the upper surface of the sealing cover 11. A protective sleeve 18 is fixedly connected to the middle of the outer surface of the positive and negative threaded screw 17. Through the cooperation between the adjustment port 19 and the protective sleeve 18, it is convenient for the operator to reach into the sealing cover 11 to rotate the positive and negative threaded screw 17 for adjustment purposes.

[0023] The working principle of this utility model is as follows: When in use, the battery pack is placed inside the housing 1, and then the sealing cover 11 is placed on the housing 1. The operator reaches into the adjustment port 19, holds the protective sleeve 18, and drives the positive and negative threaded screw 17 to rotate. When the positive and negative threaded screw 17 rotates, it can drive the sliding plates 20 to move closer together. When the sliding plates 20 move closer together, they can drive the fixing plates 10 to move closer together. When the fixing plates 10 move closer together, the battery pack can be protected inside the fixing plates 10, and the battery pack can also be fixed. The housing 1 is equipped with a reinforcing plate 4 and a strong spring 5, which can directly increase the strength of the housing 1. The strong spring 5 plays a buffering role and can buffer the impact force received by the housing 1, thus solving the problem of insufficient strength of the housing 1 used for the battery pack.
