CN-122008942-A - Battery tray

Abstract

The invention provides a battery tray, which comprises a tray body and a through hole, wherein the tray body is used for placing a battery pack, the through hole is formed in the tray body and used for avoiding an unlocking piece, and the unlocking piece is used for penetrating the through hole and inserting the battery pack to position and unlock the battery pack when the battery pack is placed on the tray body. The bearing and the positioning of the battery pack are respectively realized by the tray body and the unlocking piece separated from the tray body, so that the tray body can be directly formed by using a metal plate (such as a steel plate), related structures (such as a limiting block and the like) for positioning the battery pack are not required to be arranged on the tray body, and the forming is more convenient. In addition, the positioning function of the battery pack is integrated on the unlocking piece, the integration level is improved while the unlocking function is not influenced, the operation is more reliable, and the defect that the positioning and unlocking are respectively carried by the tray body (such as a limiting block arranged on the tray body) and the unlocking piece in the prior art to cause complex unlocking structure is overcome.

Description

Battery tray The application claims a division of Chinese patent application CN2022103513352 with the application date of 2022, 4 months and 2 days, named as 'battery tray and battery replacing equipment'. Technical Field The invention relates to the technical field of power conversion, in particular to a battery tray. Background With the development and popularization of new energy vehicles, the battery pack quick-change technology also develops rapidly. At present, the development of quick-change technology of small passenger cars is most mature, and batteries of the passenger cars are fixed on a chassis of the car, so that when a battery pack is replaced, special battery replacement equipment is required to be moved to the bottom of the car for battery disassembly or installation. Moreover, due to the small weight of the passenger car, the volume of the battery pack is relatively small, and the operability of battery replacement is very convenient. However, for large vehicles, such as heavy trucks or light trucks, the vehicle body and cargo weight are large, resulting in large vehicles requiring a high capacity of the battery pack, and the large vehicles must have a large enough capacity of electric energy to support hundreds of kilometers of travel, which also results in large vehicles with large battery packs. Therefore, in the prior art, large battery containers of new energy series are fixed on a girder of a vehicle in a top hanging mode, and the battery containers are arranged close to a cab, so that large potential safety hazards are brought to a driver and the vehicle in the driving process and the top hanging power change process, and personal damage is directly caused to the driver if the batteries are out of order and the like. In addition, the lifting mode has high requirements on the place of the power exchange station, and the power exchange station is required to have a large enough area to execute the battery transferring and the battery storing of the lifting equipment, so that the station building cost is high. Therefore, for large vehicles, there is a strong need for a safer and more reliable power conversion mode that is easy to popularize, for example, a chassis power conversion mode that uses passenger cars. When the battery replacing equipment adopted in the chassis type battery replacing mode of the conventional passenger car is applied to the large-sized vehicle battery replacing, a battery is placed on a battery tray, a positioning block and other structures are required to be arranged on the battery tray for positioning a battery pack placed on the battery tray, the positioning block is arranged to enable the processing and forming of the battery tray to be more complex, and the concentration degree and the working reliability of the battery tray are reduced. Disclosure of Invention The invention aims to overcome the defects that in the prior art, the processing and forming of a battery tray are more complicated and at least one of the concentration degree, the working reliability and the like of the battery tray is reduced due to the arrangement of the positioning blocks on the battery tray. The invention solves the technical problems by the following technical scheme: the invention discloses a battery tray which comprises a tray body and a through hole, wherein the tray body is used for placing a battery pack, the through hole is formed in the tray body and used for avoiding an unlocking piece, and the unlocking piece is used for penetrating through the through hole and inserting the battery pack when the battery pack is placed on the tray body so as to position and unlock the battery pack. In the scheme, the battery pack is carried and positioned by the tray body and the unlocking piece separated from the tray body respectively by adopting the structural form, so that the tray body can be directly formed by using a metal plate (such as a steel plate), related structures (such as a limiting block and the like) for positioning the battery pack are not required to be arranged on the tray body, the forming is more convenient, in addition, the positioning function of the battery pack is integrated on the unlocking piece, the integration level is improved while the unlocking function is not influenced, the work is more reliable, and the defect that the unlocking structure is complex due to the fact that the positioning and the unlocking piece are respectively born by the tray body (such as the limiting block arranged on the tray body) in the prior art is overcome. Preferably, the through hole is arranged corresponding to an unlocking mechanism built in the battery pack. In this scheme, the unlocking piece corresponds to the through holes one by one, and the through holes correspond to the unlocking mechanism of the battery pack, and the unlocking piece can be understood to correspond to the unlocking mechanism of the battery pack. When the battery pack is installed, the battery pac
