[0035] The inventor finds that the application field of power batteries is constantly expanding, and the market demand is also constantly expanding. In the development process of vehicles, the placement of batteries is a difficult problem. Due to the large number of traditional automobile parts, there is no space to install batteries without extensively modifying the vehicle body. After further research, the inventor finds that traditional vehicles generally place batteries in the front cabin or trunk, and install them in the vehicle side member or spare tire pool through brackets, and the cantilever mode of the brackets is relatively weak and prone to noise generation, and the batteries and multiple electronic modules of the power supply device are generally placed separately, occupying a large amount of space, such as the electric drive or heat management space of the front cabin, reducing the space utilization rate.

[0036] In view of this, the present application provides a technical solution, in which a case is used for mounting on a vehicle body, the case includes a case body, a first mounting member and a second mounting member, the case body has an accommodating cavity, the first mounting member is installed on the case body and is used for fixing a battery in the accommodating cavity, and the second mounting member is installed on the case body and is used for fixing a plurality of electronic modules in the accommodating cavity. In the above solution, the battery and the plurality of electronic modules can be respectively fixed in the accommodating cavity of the case by the first mounting member and the second mounting member of the case, and then the case is fixed in the vehicle, and the battery and the plurality of electronic modules are integrally mounted on the vehicle body, which can improve the space utilization rate of the vehicle, improve the mode of the battery, and reduce the noise of the vehicle.

[0037] An embodiment of the present application provides a vehicle that uses a battery as a power source, and referring to FIG. 1, FIG. 1 is a structural schematic diagram of a vehicle 1000 according to some embodiments of the present application. The vehicle 1000 can be a fuel oil vehicle, a gas vehicle, or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid vehicle, or a range extender vehicle, etc. The battery 100 can be used to supply power to the vehicle 1000, for example, the battery 100 can be used as an operating power source for the vehicle 1000. The vehicle 1000 can further include a controller 200 and a motor 300, and the controller 200 is used to control the battery 100 to supply power to the motor 300, for example, for starting the vehicle 1000, navigation, and operating power consumption needs during driving.

[0038] Referring to Figures 2 and 3 together, Figure 2 is a schematic installation diagram of a power supply device according to some embodiments of the present application, and Figure 3 is a structural schematic diagram of a power supply device according to some embodiments of the present application. An embodiment of the present application provides a case 10, which is used for installation on a body 500 of a vehicle 1000, and which includes a case body 11, a first mounting member 12 and a second mounting member 13, and the case body 11 has an accommodating cavity 11a, the first mounting member 12 is installed on the case body 11 and is used for fixing a battery 100 in the accommodating cavity 11a, and the second mounting member 13 is installed on the case body 11 and is used for fixing a plurality of electronic modules 400 in the accommodating cavity 11a.

[0039] The electronic module 400 may be a DCDC (direct current converter) power supply module and may be integrated with electronic components such as relays, sensors, resistors, and capacitors, and a plurality of electronic modules 400, together with the battery 100, constitute a power supply device and are used to supply power to the vehicle 1000. The case body 11 may include a top cover 111 and a bottom cover 112, which are placed over each other and together define a receiving cavity 11a. The bottom cover 112 may have a hollow structure with one end open, and the top cover 111 may have a plate-like structure, with the top cover 111 covering the opening side of the bottom cover 112, so that the top cover 111 and the bottom cover 112 together define the accommodation cavity 11a, and the top cover 111 and the bottom cover 112 may both have a hollow structure with one end open, with the opening side of the top cover 111 covering the opening side of the bottom cover 112. Of course, the case body 11 may have various shapes, such as a cylinder, a rectangular parallelepiped, etc.

[0040] In the above solution, the battery 100 and the multiple electronic modules 400 can be fixed in the accommodating cavity 11a of the case 10 by the first mounting member 12 and the second mounting member 13 of the case 10, respectively. The case 10 is then fixed in the vehicle 1000, and the battery 100 and the multiple electronic modules 400 are mounted as a unit to the body 500 of the vehicle 1000, thereby improving the space utilization rate of the vehicle 1000 and avoiding the battery 100 being mounted to the side member or spare tire pool via the bracket 121, preventing the relatively weak cantilever mode of the bracket, improving the mode of the battery 100, and reducing the noise of the vehicle 1000.

[0047] The connection portion 141 and the top cover 111 may be connected by welding, bolts, or the like. For example, the connection portion 141 is annular and welded to the top cover 111. The connection portion 141 may be provided along the circumferential direction of the protruding portion 142, or may be provided along a part of the circumferential side of the protruding portion 142. The protruding portion 142 protrudes toward the rear seat, facilitating a fixed connection with the rear seat. A screw hole may be formed in the protruding portion 142, and the screw may be inserted through the screw hole and then fixed to the rear seat, and the protruding portion 142 may be fixed to the rear seat by a method such as a lock.

[0048] In the above solution, the top cover 111 serves as a support for the rear seat, and meets the need to prevent the seat from crawling under, which not only improves the mode of the top cover 111, but also saves the space required for the seat support plate.

[0049] In some embodiments, the case 10 further includes a fourth mounting member 15 installed on the outer surface of the case body 11, the fourth mounting member 15 being used to secure the case body 11 to the floor of the vehicle body 500.
