[0023] Hereinafter, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. The following description of at least one exemplary embodiment is actually only an example, and is not intended to be any limitation on the present application and its application or use. Based on the embodiments of the present application, all other embodiments that a person skilled in the art can obtain without creative labor fall within the scope of protection of the present application.

[0024] Example 1 With the development of new energy technology, the application of new energy batteries becomes more and more widespread, and people's requirements for the installation and cost of new energy batteries gradually increase.

[0025] This embodiment provides a new energy vehicle, which is equipped with a new energy battery and can be driven, thereby effectively saving energy, and the charging consumption cost is much lower than the fuel cost, so that the new energy vehicle is advantageous for reducing the user's transportation costs.

[0026] In the related technology, the new energy battery is installed in the new energy vehicle by a battery frame, and the battery frame and the lock base are directly and rigidly connected by metal, and there is no buffer structure between the battery frame and the lock base. The battery frame requires high rigidity and strength, which increases costs and reduces safety performance.

[0027] In order to solve the above problems, this embodiment provides a battery replaceable battery system including a battery frame 100, a lock base 200, a lock assembly 300, and a first elastic member 400. The battery frame 100 is for mounting a battery pack, and is provided on the lock base 200. The lock assembly 300 elastically presses the battery frame 100 against the lock base 200, and the first elastic member 400 is provided between the lock base 200 and the battery frame 100.

[0028] This battery replaceable battery system uses the first elastic member 400 to absorb the vibration of the battery frame 100 caused by the vibration of the new energy vehicle and mitigate the rigid collision between the battery frame 100 and the lock base 200, thereby reducing the requirements for the rigidity and strength of the battery frame 100, which is advantageous for reducing the cost of the battery frame 100, as well as reducing the impact of vibration on the battery pack and improving the safety performance of the battery pack.

[0029] As a preferred technical means, the battery replaceable battery system further includes a lock block 600, which is provided on the battery frame 100, and the lock block 600 is located between the pressing head of the lock assembly 300 and the battery frame 100, thereby transmitting the pressure of the pressing head to the battery frame 100 and improving the stability of fixing the battery frame 100.

[0030] The term "elastic pressing" refers to the fact that, when the system is operating, the first elastic member 400 is in a compressed state under the gravitational force of the battery frame 100. When the new energy vehicle is shaken and the battery frame 100 moves upward under the action of inertia, the rebound force of the first elastic member 400 acts on the battery frame 100 to support the battery frame 100 and move the entire battery frame 100 upward, and the force also acts on the lock block 600 in the battery frame 100 to prevent the battery frame 100 and the lock block 600 from being separated and causing a rigid collision.

[0031] As a preferred technical measure, the first elastic member 400 may be selected as a rubber block, which has a certain elasticity and strength, and is disposed between the lock base 200 and the battery frame 100, which can not only provide a certain support for the battery frame 100, but also cushion the vibration of the battery frame 100. At the same time, the rubber block is a common material, which is easy to procure and has a low cost.

[0032] Preferably, the lock assembly 300 includes a driving member, a transmission mechanism, and a pressing head. The transmission mechanism is provided at an output end of the driving member, and the pressing head is provided at one end of the transmission mechanism remote from the driving member, and the driving member can drive the pressing head through the transmission mechanism to press the battery frame 100, thereby realizing the position of the battery frame 100 to be pressed and fixed, and preventing the battery frame 100 from moving while the vehicle is running.

[0033] Preferably, the transmission mechanism is a multi-link assembly, which is advantageous in amplifying the output of the lock assembly 300 and improving the stability of the lock assembly 300 fixing the battery frame 100 .

[0034] As a preferred technical measure, the battery exchange type battery system further includes a second elastic member 500, which is provided in the transmission path of the driving force of the lock assembly 300. In the process of the new energy vehicle shaking and the battery frame 100 vibrating, the battery frame 100 moves upward due to the upward inertial force, and the battery exchange type battery system has a second elastic member 500, in this case, when the second elastic member 500 is compressed and the battery frame 100 moves downward due to the inertial force, the second elastic member 500 rebounds, and the battery exchange type battery system rebounds to press the lock block 600 downward.

[0035] During the entire vibration process, the elastic action of the first elastic member 400 and the second elastic member 500 cushions the vibration of the battery frame 100, ensures that the battery frame 100 and the lock assembly 300 contact each other but do not separate, and cushions the battery frame 100 and does not collide with the lock assembly 300.

[0036] Furthermore, the second elastic member 500 may be a spring, and when the lock assembly 300 is in a pressing state, the spring can absorb the displacement transmitted from the lock assembly 300, thereby realizing the purpose of buffering the vibration of the new energy vehicle. Specifically, the spring is provided at one end of the lock assembly 300 away from the lock base 200 along the vertical direction, and is fitted onto the driving member of the lock assembly 300. In the process in which the new energy vehicle is shaken and the battery frame 100 vibrates, the battery frame 100 moves upward due to the upward inertial force, and in this case, the spring is compressed to provide an upward reaction force to the lock assembly 300.

[0037] The spring is in a compressed or initial state. The spring is a normal elastic member, which is easy to obtain and has a low cost. At the same time, the operator can select a spring with a corresponding elastic coefficient according to the vibration condition of the battery frame 100, which is advantageous to further improve the safety performance of the battery exchange battery system.

[0038] At the same time, the second elastic member 500 may be a cylinder. When the lock assembly 300 is in a pressing state, the cylinder can absorb the displacement transmitted from the lock assembly 300, thereby realizing the purpose of buffering the vibration of the new energy vehicle. Specifically, in the process of the new energy vehicle shaking and the battery frame 100 vibrating, the battery frame 100 moves upward due to the upward inertial force, in this case, the cylinder is compressed, and the cylinder adjusts the internal air pressure, thereby providing an upward reaction force to the lock assembly 300, thereby achieving the purpose of buffering. In this case, the cylinder provides a driving force for pressing the battery frame 100 and has a buffering effect.

[0039] In addition, the second elastic member 500 is a spring built into a cylinder, and absorbs the displacement transmitted from the lock assembly 300 by the spring, thereby achieving the purpose of cushioning the vibration of the new energy vehicle.

[0040] Preferably, the battery replaceable battery system further includes a battery replaceable base 800, which supports the lock base 200 and the lock assembly 300 by fixing the lock base 200 and the lock assembly 300, and modularizes the battery replaceable battery system, making it convenient for workers to assemble and maintain.

[0041] In addition, there are multiple sets of lock assemblies 300, and the multiple sets of lock assemblies 300 are arranged at intervals along the circumferential direction of the battery frame 100, thereby improving the safety and stability with which the lock assemblies 300 secure the battery frame 100.

[0042] Example 2 Example 2 provides a battery-replaceable battery system, the main configuration of which is the same as that of Example 1, and in order to avoid redundancy, this example will only describe the differences from Example 1.

[0043] In this embodiment, the battery exchange type battery system does not have a second elastic member 500, but further includes a third elastic member 700 provided between the battery frame 100 and the lock block 600.

[0044] During the vibration process of the battery frame 100, when the inertial force of the battery frame 100 is upward, there is a third elastic member 700 between the lock block 600 and the lock assembly 300, at this time, the third elastic member 700 is compressed and the first elastic member 400 rebounds, and when the new energy vehicle shakes and the battery frame 100 vibrates, the battery frame 100 moves up and down. When the battery frame 100 moves upward, the third elastic member 700 is compressed under the force and the first elastic member 400 rebounds, thereby ensuring that the battery frame 100 and the lock block 600 are always in contact with each other, and avoiding rigid collision between the battery frame 100 and the lock block 600.

[0045] When the battery frame 100 moves downward, the third elastic member 700 rebounds and the first elastic member 400 is compressed, so that the battery exchange type battery system can ensure that the battery frame 100 and the lock block 600 are still in constant contact with each other and avoid rigid collision between the battery frame 100 and the lock block 600. During the entire vibration process of the battery exchange type battery system, the compression and rebound of the first elastic member 400 and the third elastic member 700 realizes that the battery frame 100 and the lock block 600 are in floating contact and do not separate, so that the shock absorbing function of the battery exchange type battery system is realized and no impact collision occurs.

[0046] The above shows and describes the basic principle and main features of the present application, as well as the advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above-mentioned examples, and the above examples and description are only illustrative of the principles of the present application, and various modifications and improvements of the present application are within the scope of the appended claims, as defined by the appended claims and their equivalents, without departing from the spirit and scope of the present application.
