Description

TECHNICAL AREA The present application relates to the field of battery technology, for example a hanging bracket and a battery pack for this hanging bracket. STATE OF THE ART With the development from combustion engine vehicles to purely electric vehicles, the hybrid vehicle is undoubtedly one of the preferred technological solutions in the current phase. Currently, the battery pack is designed in several modules as a profile housing, with the extruded aluminum profiles used offering the advantages of light weight and high corrosion resistance. Aluminum profile housings are expensive and have comparatively low structural strength, necessitating the creation of hollow structures for reinforcement. Furthermore, the chips generated during machining by existing production machines tend to accumulate in the hollow space, making cleaning difficult, potentially causing noise, and posing a short-circuit risk. Additionally, water easily collects at the connection points between the battery pack housing and the vehicle chassis, which, if left unattended for an extended period, can lead to corrosion of the battery pack housing. CONTENT OF THE PRESENT APPLICATION In the first aspect, this registration offers a comprehensive mounting bracket: a first suspension element, wherein the first suspension element has a support section and a fastening section, wherein the support section is oriented towards the battery pack housing, and wherein the first support section serves to be connected to the bottom of the battery pack housing; a second suspension element, wherein the second suspension element has a stop section and a mounting section, wherein the stop section is oriented towards the battery pack housing, and wherein the stop section serves to be connected to the side wall of the battery pack housing; wherein the fastening section is connected to the mounting section in order to connect the first suspension element to the second suspension element. In the second aspect, this registration offers a comprehensive battery pack: a case; A suspension bracket as described above, wherein at least two groups of suspension brackets are provided, each suspension bracket being connected to the opposite side walls and the bottom of the housing. By arranging a first suspension element and a second suspension element, the support section of the first suspension element is designed to connect to the bottom of the battery pack, while the stop section of the second suspension element is connected to the side wall of the battery pack. The mounting section of the first suspension element is connected to the mounting section of the second suspension element to connect the first suspension element to the second suspension element. This ensures that both the support section and the stop section are oriented towards the battery pack, so that the pressure exerted by the battery pack is distributed between the first and second suspension elements, respectively. This results in improved force transmission, prevents the pressure from being concentrated entirely on the suspension bracket, reduces stress fatigue in the suspension bracket, and extends the service life of the suspension bracket.
