Description

Technical Field

[0001] The utility model relates to the field of battery assembly structures, in particular to a hanging basket type bracket for a battery pack of an electric vehicle. Background Art

[0002] Electric vehicles use power batteries as their driving force. The battery pack, as the vehicle's power source, is crucial in the development of pure electric vehicles. The battery pack is secured to the vehicle body or frame via a battery pack bracket. To cope with complex road conditions, the battery pack and its mounting structure must exhibit excellent performance.

[0003] Prior art battery pack brackets utilize a single aluminum-plastic shell encasing the battery, with holes drilled into the shell for mounting and wiring. While this integrated shell structure fully encloses the battery, it offers excellent mounting performance but is relatively heavy and suffers from poor heat dissipation.

[0004] In light of this, this technical solution proposes a hanging basket-style bracket for electric vehicle battery packs. This bracket features functional mounting holes and excellent structural strength. Furthermore, considering that current battery packs often have an integral outer packaging frame, a hollow frame is used to "snag" the battery pack into the frame, with only a few fixing points used to connect it to external fixtures or other battery packs. The overall structure is simple and robust, with excellent heat dissipation performance and easy installation and maintenance. Utility Model Content

[0005] The technical solution of this utility model aims to at least partially solve one of the technical problems in the related art. To this end, the main purpose of this utility model is to provide a hanging basket bracket for electric vehicle battery packs, aiming to solve the problem that the battery pack fixing structure in the prior art lacks both heat dissipation performance and fixing strength.

[0006] To achieve the above-mentioned purpose, the utility model provides a hanging basket bracket for an electric vehicle battery pack, comprising a frame shell body,

[0007] The frame body forms a groove on one side, a hollow position is opened on one side of the bottom of the groove, and a baffle is formed on the other side. The baffle is provided with a wiring hole and a head fixing position.

[0008] A bracket is provided on one side of the hollow position and at the edge above the trough body. The bracket extends toward one side of the baffle, and the extension length is greater than 1 / 2 of the width of the trough body. The length of the bracket is greater than 1 / 2 of the length of the trough body, and a connecting hole is provided on the surface of the bracket.

[0009] As a further solution of the present invention, a panel area is provided at the bottom of the frame body.

[0010] As a further solution of the present invention, the panel area includes a knob fixing hole and a liquid crystal fixing hole.

[0011] As a further solution of the present invention, the middle section of the bracket is outwardly expanded, and heat dissipation holes are provided on the surface of the outwardly expanded structure.

[0012] As a further solution of the present invention, a frame fixing hole is provided on the edge of the frame shell body.

[0015] The beneficial effects of the utility model are as follows:

[0016] This utility model proposes a hanging basket-style bracket for electric vehicle battery packs. The bracket, which features a hollowed-out frame and inwardly extending brackets, allows for placement of battery cells (battery packs) within the hollowed-out frame. With the brackets securing one side of the battery pack and the top of the battery pack positioned behind the other side of the baffle, assembly is possible without the need for additional fixings. The overall structure is simple, with multiple holes reserved within the basic frame. This ensures full functional performance while maintaining good structural strength, making it easy to assemble with battery packs or external fixtures. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] as follows:

[0024] Please see the attached Figure 1-3 ,

[0025] The main structure includes a frame body 1,

[0026] The frame body 1 forms a groove body 10 on one side, and a hollow position 12 is opened on one side of the bottom of the groove body 10. A baffle 11 is formed on the other side. The baffle 11 is provided with a wiring hole 100 and a head fixing position 101. On one side of the hollow position 12, a bracket 14 is provided at the edge above the groove body 10. The bracket 14 extends toward the side of the baffle 11, and the extension length is greater than 1 / 2 of the width of the groove body 10. The length of the bracket 14 is greater than 1 / 2 of the length of the groove body 10, and a connection hole 140 is provided on the surface of the bracket 14.

[0027] Here's how it works:

[0028] When placing the battery pack, the battery pack is placed by inserting it obliquely on one side of the surface of the baffle 11. At this time, the two sides of the battery pack are respectively the bracket 14 and the baffle 11 at the head position. The baffle 11 is further fixed by the head fixing position 101. The wire is pulled out through the wiring hole 100, and the bracket 14 is further fixed to the battery pack through the connection hole 140. Since a hollow part is left in the middle of the tank body 10, the contact area between the battery pack body and the external space is large, which is conducive to the dissipation of working heat. The frame shell body 1 can be a cast plastic shell or a plastic-coated aluminum shell structure. Due to the "hollowed out" tank body 10 and the hollow part, the frame shell body 1 itself is light in weight, has good ductility, and is not easy to burst.

[0029] In a preferred embodiment of the present invention, a panel area 13 is provided at the bottom of the frame body 1 .

[0030] The panel area 13 is used to install a panel with power management. For example, the panel area 13 can be used to install a control knob and a liquid crystal screen through the knob fixing hole 130 and the liquid crystal fixing hole 131.

[0031] In a preferred embodiment of the present invention, the middle portion of the bracket 14 is outwardly expanded, and heat dissipation holes 141 are provided on the surface of the outwardly expanded structure.

[0032] The outwardly flared bracket 14 is used to increase the space between the bracket and the bottom (hollow portion) of the tank body 10, facilitating the assembly of the battery pack and increasing the spacing. The connection hole 140 provided in the outwardly flared portion facilitates fixing to an external fixing member.

[0033] A preferred embodiment of the present invention: a frame fixing hole 15 is provided on the edge of the frame shell body 1 .

[0034] The frame fixing holes 15 are used to fix the battery pack to the external large frame when the battery pack is at the corner of the entire battery pack.

[0035] In a preferred embodiment of the present invention, the bracket 14 is a one-piece bending-molded structure of hardware.

[0036] For example, the bracket 14 structure can be formed by bending an aluminum strip having good structural strength and thermal conductivity.

[0037] In a preferred embodiment of the present invention, the bracket 14 is connected to the frame body 1 by welding.

[0038] The bracket 14 can be an integral structure with the frame body 1 , or a structure that is welded after the battery pack is installed.

[0039] The above are only preferred embodiments of the technical solution of the present utility model, and do not limit the patent scope of the technical solution of the present utility model. All equivalent structural transformations made by using the contents of the description and drawings of the technical solution of the present utility model under the conception of the technical solution of the present utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the technical solution of the present utility model.
