Description

Shock-absorbing type battery pack mounting rack Technical Field The utility model relates to the technical field of battery packs, in particular to a shock-absorbing type battery pack mounting rack. Background The battery pack mounting rack is a structural member for fixing and supporting a battery pack and is widely applied to electric automobiles, energy storage equipment and other battery powered devices. The main function of the battery pack is to ensure that the battery pack always keeps a stable position in the use process, and prevent the battery pack from being displaced or damaged due to external factors such as vibration, impact and the like. A well-designed battery pack mounting rack not only can provide reliable fixing effect, but also has functions of shock resistance, heat dissipation, water resistance and the like so as to improve the safety and the service life of the battery pack. Through reasonable structural design and material selection, the battery pack mounting rack can effectively solve various problems of the battery in the operation process, so that the performance and reliability of the whole vehicle or equipment are improved. The patent with the publication number CN212737728U discloses an automobile battery pack mounting bracket, which comprises a first transverse plate, the bottom laminating of first transverse plate has an automobile battery pack, the bottom of first transverse plate is equipped with the chassis, the top left and right sides of first transverse plate all is equipped with fixture, the outer wall rigid coupling of plate body has the rubber pad, two the outer wall of rubber pad laminates with the outer wall left and right sides of automobile battery pack respectively, the bottom rigid coupling of first spring is in the top of first transverse plate. This car group battery installing support for plate body and rubber pad accessible first spring's elastic deformation places car group battery fixed centre gripping in the bottom of first diaphragm, and car group battery installation and dismantlement of being convenient for make when the chassis produces to rock, the sliding sleeve carries out the opposite movement at the outer wall of slide rail, and the inner wall of first montant is shifted into to the second montant, and then makes second spring and third spring carry out elastic deformation, cushions first diaphragm and car group battery. Although the above-mentioned prior art realizes the cushioning effect by the second spring and the third spring, there are certain disadvantages. First, when the battery pack is subjected to vibration or impact, the repeated expansion and contraction of the second spring and the third spring cannot effectively absorb the vibration energy, so that the battery pack still faces a large shaking risk. The shaking not only prolongs the relative movement time between the battery pack and the mounting frame, but also can cause multiple impacts on the structure of the mounting frame, thereby shortening the service life of the mounting frame. In addition, the long shaking time may cause fatigue of mechanical parts inside the battery pack, affecting the overall performance of the battery pack. Therefore, to address these shortcomings, we propose a shock absorbing battery pack mounting rack, aiming at improving the stability and safety of the battery pack and reducing the influence of shock on the battery pack and the mounting rack by optimizing a shock absorbing mechanism.
