Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle capacitors, specifically to a vehicle capacitor housing and a vehicle capacitor. Background Technology
[0002] Automotive capacitors are one of the key components in new energy vehicles. Their casings contain busbars, capacitor cores, electrodes, etc., and are sealed with sealant. To meet market demands, manufacturers typically produce more than one model of automotive capacitor. The casings of automotive capacitors are usually injection molded from plastic. Each product requires a unique casing design and corresponding injection mold, which is not only costly and time-consuming but also inconvenient for warehouse material management. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a vehicle-mounted capacitor housing that is versatile, applicable to more than one product, reduces R&D and production costs, and facilitates material management.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0005] This utility model provides a vehicle-mounted capacitor housing, including an outer shell and a partition. The outer shell forms a cavity inside, and an opening is provided on one side of the cavity. The side wall of the cavity is provided with a groove for accommodating the edge of the partition. The partition can be inserted into the groove from the opening or pulled out from the opening for removal. When the partition is installed in the groove, it divides the cavity into an upper cavity and a lower cavity.
[0006] As a preferred embodiment, the partition is square, and the sidewall of the cavity is provided with upper limit ribs and lower limit ribs, and the upper limit ribs and lower limit ribs form a groove for wrapping the three edges of the partition.
[0007] As a preferred option, the top or bottom surface of the partition is provided with reinforcing ribs to prevent the partition from deforming.
[0008] As a preferred embodiment, the bottom surface of the partition plate has a concave-convex structure.
[0009] As a preferred embodiment, the outer shell is a one-piece molded plastic structure.
[0010] This utility model also provides a vehicle-mounted capacitor, including a capacitor housing, a partition installed in the housing to form an upper cavity and a lower cavity inside the housing, a capacitor core and a busbar installed in the lower cavity, the capacitor core being connected to the busbar, the busbar partially extending out of the housing from an opening, and sealant filling the lower cavity.
[0011] The vehicle-mounted capacitor housing provided by this utility model has the following advantages:
[0012] The vehicle-mounted capacitor housing provided by this utility model includes an outer shell and a partition. The partition is detachable. When the partition is installed in the outer shell, it divides the internal cavity of the outer shell into an upper cavity and a lower cavity. The lower cavity can be used to install components such as battery cells and busbars. Only the lower cavity needs to be potted. If the partition is removed, the internal cavity of the outer shell is larger and can be used to install components such as battery cells and busbars of other types of vehicle-mounted capacitors. Therefore, by configuring a detachable partition, this vehicle-mounted capacitor housing can be used for more than one product. Attached Figure Description
[0013] Figure 1 This is an exploded view of the vehicle-mounted capacitor according to an embodiment of the present invention;
[0014] Figure 2 yes Figure 1 Enlarged view of point A in the middle. Detailed Implementation
[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0016] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0017] like Figures 1 to 2 As shown, this embodiment provides a vehicle-mounted capacitor housing, including an outer shell 1 and a partition 2. The outer shell 1 has an interior cavity 3 with an opening on one side. The side wall of the cavity 3 has a groove 4 for accommodating the edge of the partition 2. The partition 2 can be inserted into the groove 4 from the opening or removed from the opening for removal. When the partition 2 is installed in the groove 4, it divides the cavity 3 into an upper cavity and a lower cavity. By configuring the removable partition 2, this vehicle-mounted capacitor housing can be used for more than one product.
[0018] As a preferred embodiment, the outer casing 1 is a one-piece molded plastic structure. Existing vehicle capacitor casings are typically made of plastic. The vehicle capacitor casing provided in this embodiment can be applied to more than one product, increasing versatility and thus saving on R&D and mold-making costs.
[0019] Since most vehicle-mounted capacitors are generally square in shape, preferably, the partition 2 in this embodiment is square. An upper limit rib 5 and a lower limit rib 6 are provided on the sidewall of the cavity 3, and a groove 4 is formed between the upper limit rib 5 and the lower limit rib 6 to enclose the three edges of the partition 2. In other embodiments, the shape of the outer shell 1 is not limited to square, and the shape of the partition 2 matches the internal shape of the outer shell 1.
[0020] As a preferred embodiment, the top or bottom surface of the partition 2 is provided with reinforcing ribs 7 to prevent deformation of the partition 2.
[0021] This embodiment also provides a vehicle-mounted capacitor. A partition 2 is installed in the housing 1 to form an upper cavity and a lower cavity inside the housing 1. The lower cavity houses a capacitor core 8, a busbar 9, a grounding electrode 10, etc. The capacitor core 8 is connected to the busbar 9, and the busbar 9 partially extends out of the housing 1 from an opening. A sealant 11 fills the lower cavity. The sealant 11 is epoxy resin or UV adhesive.
[0022] As a preferred embodiment, the bottom surface of the partition 2 is provided with a concave-convex structure, which can increase the contact area between the sealant 11 and the partition 2, and increase the stability of the partition 2 after potting.
[0023] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model 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 of the technical features. These modifications or substitutions do not cause the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model. Therefore, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
