[0002] As the development direction of future transportation tools, electric vehicles have received extensive attention and applications in recent years. As the core component of an electric vehicle, the performance of the battery directly affects the driving range and user experience of the electric vehicle. To facilitate the replacement and maintenance of the battery, electric vehicles are usually equipped with a battery compartment at the chassis for storing and protecting the battery.

[0003] The existing battery compartment technology mainly has the following disadvantages:

[0004] Complex structure and high cost: The existing battery compartment is usually equipped with a battery driving device inside, which is used to move the battery out of the battery compartment and send the battery to the battery swapping cabinet. This design increases the complexity of the battery compartment, improves the manufacturing cost and failure rate.

[0005] Low space utilization rate: Due to the existence of the battery driving device, the thickness or width of the battery compartment is usually large, resulting in a reduction in the space utilization rate of the bottom of the electric vehicle, a decrease in the number of batteries carried at the bottom, and thus affecting the driving range of the electric vehicle.

[0006] Low replacement efficiency: The existing battery replacement method usually requires the cooperation of the driving device inside the battery compartment and the battery swapping device, with a complex operation process and low replacement efficiency. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a battery compartment and an electric vehicle to solve the problems raised in the above background art.

[0009] A battery compartment is installed at the bottom of an electric vehicle. The battery compartment is of a cuboid structure, and an opening structure for the battery to enter and exit is provided on any side wall along the length direction of the battery compartment.

[0010] Guide and limit strips for fixing the battery are arranged inside the battery compartment.

[0011] Further, a bending type fixing structure is arranged inside the side of the battery compartment away from the opening structure.

[0012] The utility model also provides an electric vehicle. A frame is arranged at the bottom of the electric vehicle, and the battery compartment as described above is accommodated inside the frame;

[0013] A locking structure for fixing or releasing the battery compartment is arranged inside the frame.

[0014] Furthermore, a plurality of the frames are provided at the bottom of the electric vehicle, and each of the frames can accommodate one of the battery compartments.

[0015] Furthermore, the plurality of battery compartments are arranged in a manner that their length directions are parallel or perpendicular or a combination of parallel and perpendicular to the driving direction of the electric vehicle.

[0016] Furthermore, a notch for the battery compartment to enter and exit is formed at the bottom end of the frame.

[0017] It can be seen from the above technical solutions that, compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] The present utility model cancels the driving device inside the battery compartment, reduces the volume of the battery compartment, thereby increasing the number of batteries that can be carried and making full use of the space at the bottom of the electric vehicle; the structure of the battery compartment is simplified, the number of devices is reduced, thereby reducing the manufacturing cost and failure rate of the battery compartment.

[0029] In order to better understand the purpose, structure, and function of the present utility model, the following further detailed description of the present utility model will be made with reference to the drawings. Embodiment 1

[0030] Refer to Figure 1 - Figure 2 As shown, a battery compartment provided in this embodiment is installed at the bottom of an electric vehicle; the battery compartment 1 is in a cuboid structure, and an opening structure 2 for the battery to enter and exit is provided on any side wall of the battery compartment 1 along its length direction;

[0031] A guiding and limiting strip 3 for fixing the battery is provided inside the battery compartment 1;

[0032] A bent fixing structure 4 is provided inside the side of the battery compartment 1 far from the opening structure 2.

[0033] Specifically, the battery can enter and exit the inside of the battery compartment 1 through the opening structure 2. When the battery extends into the inside of the battery compartment 1, the groove on the side wall of the battery can be adapted to the guiding and limiting strip 3, which can not only guide the battery to smoothly enter the inside of the battery compartment 1, but also play a fixing role.

[0034] It should be noted that two guide limit strips 3 are provided, which are respectively installed on the two side walls in the length direction of the battery compartment 1, and the end of the guide limit strip 3 close to the opening structure 2 is an oblique cone structure, which can facilitate the guide limit strip 3 to be inserted into the groove on the side wall of the battery.

[0035] It should be noted that the bent fixing structure 4 is used to support the end of the battery extending into the battery compartment 1 . Embodiment 2

[0036] See also Figure 3 As shown, this embodiment provides an electric vehicle, a frame 5 is arranged at the bottom of the electric vehicle, and the frame 5 contains the battery compartment 1 of the first embodiment;

[0037] A locking structure 6 for fixing or releasing the battery compartment 1 is arranged in the frame 5 .

[0038] It should be noted that a notch is provided at the bottom of the frame 5 for the battery compartment 1 to enter and exit.

[0039] Specifically, the utility model deletes the driving device in the battery compartment 1 in the conventional technology, and changes the internal frame of the battery compartment 1. The battery compartment 1 is only used to carry and protect the battery. When the locking structure 6 releases the battery compartment 1, the battery compartment 1 sinks as a whole onto the transfer cart under the action of gravity. The transfer cart transfers the battery compartment 1 to the battery swap cabinet, and the battery grabbing device in the battery swap cabinet grabs the battery in the battery compartment 1 into the battery swap cabinet. The loading process of the new battery can be the opposite of the above process.

[0040] The driving device inside the battery compartment 1 is eliminated, and the volume of the battery compartment 1 is reduced, so that the number of batteries installed can be increased and the space at the bottom of the electric vehicle can be fully utilized; the structure of the battery compartment 1 is simplified, and the number of devices is reduced, thereby reducing the cost and failure rate of the battery compartment 1.

[0041] To further optimize the solution, multiple frames 5 can be set at the bottom of the electric vehicle, each frame 5 can accommodate a battery compartment 1, and the multiple battery compartments 1 are arranged in a manner that their length direction is parallel or perpendicular to the driving direction of the electric vehicle, or a combination of parallel and perpendicular ( Figure 3 One arrangement is shown).

[0042] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. At the same time, for those skilled in the art, according to the ideas of the utility model, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the utility model.
