Description

Technical Field

[0001] This utility model belongs to the field of sealing technology, specifically relating to irregularly shaped sealing components for new energy battery packs. Background Technology

[0002] The sealing performance of power batteries is crucial to their safety and reliability. Currently, power battery packs must meet IPX7 or even IPX8 protection levels in immersion tests.

[0003] Traditional battery packs typically include a top cover, a sealing gasket, a lower housing, and fastening bolts. The sealing gasket is located between the top cover and the lower housing, and is secured by the fastening bolts passing through the top cover and the lower housing to ensure a tight seal at the connection between them. Therefore, the sealing and compression performance of the sealing gasket significantly affects the safety of the battery pack. Utility Model Content

[0004] The purpose of this utility model is to provide an irregularly shaped sealing component for new energy battery packs to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: it includes a sealing component, the upper surface of which is further provided with an outer ring and an inner ring, both of which are provided with grooves, and the grooves are provided with colloid.

[0005] It should be noted in the solution that the gel is wrapped with a film, and the film has an inner groove and an outer groove, with the inner groove corresponding to the outer groove.

[0006] It should be noted in the solution that the outer side of the seal is provided with several external grooves, and the inner side of the seal is provided with several internal protrusions.

[0007] It should be noted in the solution that the sealing element is provided with several positioning holes.

[0008] Compared with the prior art, the irregular-shaped sealing component for new energy battery packs provided by this utility model has at least the following beneficial effects:

[0009] (1) Through the setting of the thin film, in actual use, the seal is installed in the mounting groove of the battery pack. When the battery pack is closed, the seal is squeezed. During the squeezing process, the outer ring and inner ring are squeezed first, and the thin film inside the outer ring and inner ring is squeezed second. After the film is squeezed, it will break, causing the colloid inside the film to flow out. During the continuous closing process of the battery pack, the colloid will fill the gap between the seal and the battery pack. After a period of time, the colloid solidifies and tightly connects the seal and the battery pack together, which can play a better protective role and can also prevent the direct injection of colloid from causing some of the colloid to solidify.

[0010] (2) By setting the positioning hole, in the actual installation process, the positioning post and the mounting groove corresponding to the positioning hole are set on the battery pack. When the battery pack is closed, the seal is squeezed. Since the positioning post and the positioning hole cooperate with each other to limit the position of the seal, the position of the seal will not be displaced after installation, thus achieving better sealing and installation effect.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 A new energy battery pack irregular-shaped sealing component includes a sealing component 1. The upper surface of the sealing component 1 is also provided with an outer ring 3 and an inner ring 4. Both the outer ring 3 and the inner ring 4 are provided with grooves. The grooves are provided with a colloid 8. The colloid 8 is wrapped with a film 7. The film 7 is provided with an inner groove 9 and an outer groove 10. The inner groove 9 and the outer groove 10 correspond to each other.

[0018] With the membrane 7 in place, during actual use, the seal 1 is installed in the mounting groove of the battery pack. When the battery pack is closed, the seal 1 is squeezed. During the squeezing process, the outer ring 3 and inner ring 4 are squeezed first, followed by the membrane 7 inside the outer ring 3 and inner ring 4. After being squeezed, the membrane 7 will rupture, causing the colloid 8 inside the membrane 7 to flow out. As the battery pack continues to close, the colloid 8 will fill the gap between the seal 1 and the battery pack. After a period of time, the colloid 8 will solidify and tightly connect the seal 1 and the battery pack together, which can achieve better protection and prevent the colloid 8 from solidifying due to direct injection.

[0019] Furthermore, referring to Figure 1-4 As shown, it is worth noting that the outer side of the sealing element 1 is provided with several outer grooves 5, and the inner side of the sealing element 1 is provided with several inner protrusions 6.

[0020] With the setting of the outer groove 5 and the inner protrusion 6, in order to meet the installation of the battery pack during actual use, a number of outer grooves 5 and inner protrusions 6 are provided on the sealing element 1, and the outer grooves 5 and inner protrusions 6 cooperate with the installation of the battery pack.

[0021] During installation, the existing seal 1 is installed in the mounting groove of the battery pack. When the battery pack is closed, the seal 1 is squeezed. During the squeezing process, the battery pack cannot guarantee that the seal 1 is squeezed at the same time, causing the seal 1 on one side to be subjected to pressure and deform to the other side first. This results in the seal 1 being displaced after installation, affecting the sealing effect.

[0022] To solve this problem, further, refer to Figure 1-4 As shown, it is worth noting that the sealing element 1 is provided with a plurality of positioning holes 2;

[0023] By setting the positioning hole 2, during the actual installation process, a positioning post and a mounting groove corresponding to the positioning hole 2 are set on the battery pack. When the battery pack is closed, the seal 1 is squeezed. Since the positioning post and the positioning hole 2 cooperate with each other to limit the position of the seal 1, the position of the seal 1 will not be displaced after installation, thus achieving a better sealing and installation effect.

[0024] The above describes the irregular-shaped sealing component for the new energy battery pack provided by this utility model. Specific preferred embodiments have been used to illustrate the principle and implementation of this utility model. These embodiments are only used to help understand the principle and core idea of ​​this utility model. It should be noted that for those skilled in the art, the implementation schemes in the above embodiments can be further combined or replaced without departing from the design concept of this utility model, and several improvements and modifications can be made to this utility model. These improvements and modifications also fall within the protection scope of the claims of this utility model.
