Description

Technical Field

[0001] The present invention relates to the field of new energy battery boxes, and in particular to a battery box and a vehicle. Background Art

[0002] With the development of science and technology, especially the progress of battery technology, the application of new energy vehicles is becoming more and more widespread, and container transportation has also begun to use a large number of new energy vehicles. The widespread application of new energy vehicles in the container transportation industry not only helps to reduce environmental pollution, but also reduces transportation costs and improves economic benefits.

[0003] Existing container transport vehicles usually install the container on top of the beam and place the battery box on both sides of the beam. In order to improve the vehicle's endurance, the volume and weight of the vehicle's battery box are usually set larger, so the installation position of the battery box will have a greater impact on the center of gravity of the vehicle. A center of gravity that is too high will make the vehicle more likely to lose balance, causing the vehicle to sway more and reducing the stability of the vehicle. At the same time, it will also make the vehicle tilt more obviously when accelerating and braking, reducing the adhesion between the tires and the ground, resulting in a decrease in the acceleration and braking performance of the vehicle, resulting in reduced safety during vehicle driving.

[0040] In this embodiment, the application of new energy vehicles 60 in the container transportation industry is becoming more and more widespread. In the existing container transportation vehicles 60, the container is usually installed on the top of the beam 61, and the battery box is placed on both sides of the beam 61. In order to improve the endurance of the vehicle 60, the volume and weight of the battery box of the vehicle 60 are usually set larger. Therefore, the installation position and center of gravity setting of the battery box have a greater impact on the safety and controllability of the vehicle 60. The present invention proposes a battery box, such as Figure 4As shown, the battery box may include: a frame assembly 10, a power assembly 20, a water cooling assembly 40, and a control assembly 30. The power assembly 20, the water cooling assembly 40, and the control assembly 30 may all be arranged in the hollow cavity of the frame assembly 10, so that the internal space can be effectively utilized, which also helps to achieve a more compact and neater layout, and improves the maintainability and manageability of the equipment. The frame assembly 10 may include a frame unit 11, a first box unit 12, a second box unit 13, and a third box unit 14. The first box unit 12, the second box unit 13, and the third box unit 14 may be arranged on the same side of the frame unit 11, so that the bottom space can be fully utilized, and the battery box can be prevented from occupying the cargo space or other important space, thereby improving the cargo capacity of the vehicle 60, and at the same time, the surface above the beam 61 can be relatively flat, which is convenient for the stable placement of the cargo. The first box unit 12 is detachably connected to the frame unit 11, which is convenient for the replacement and maintenance of the first box unit 12 when a failure occurs. In other embodiments, the first box unit 12 can be connected to the frame unit 11 by welding, which can increase the stability of the connection between the first box unit 12 and the frame unit 11. The second box unit 13 is detachably connected to the frame unit 11, which is convenient for replacement and maintenance of the second box unit 13 when a fault occurs. In other embodiments, the second box unit 13 can be connected to the frame unit 11 by welding, which can increase the stability of the connection between the second box unit 13 and the frame unit 11. The third box unit 14 is detachably connected to the frame unit 11, which is convenient for replacement and maintenance of the third box unit 14 when a fault occurs. In other embodiments, the third box unit 14 can be connected to the frame unit 11 by welding, which can increase the stability of the connection between the third box unit 14 and the frame unit 11. The shortest distance between the end of the second box unit 13 away from the frame unit 11 and the frame unit 11 is greater than the shortest distance between the end of the first box unit 12 away from the frame unit 11 and the frame unit 11. This design makes the hollow cavity of the second box unit 13 larger, which can flexibly accommodate power supplies of different specifications and improve the applicability of the battery box. The shortest distance between the end of the third box unit 14 away from the frame unit 11 and the frame unit 11 is greater than the shortest distance between the end of the first box unit 12 away from the frame unit 11 and the frame unit 11. This design makes the hollow cavity of the third box unit 14 larger, and can flexibly accommodate power supplies of different specifications, thereby improving the applicability of the battery box. The power supply assembly 20 may include a first battery unit 21 and a second battery unit 22. The first battery unit 21 may be arranged on a side of the hollow cavity of the second box unit 13 away from the frame unit 11, so that the center of gravity is lowered, thereby improving the stability of the vehicle 60. The first battery unit 21 is detachably connected to the second box unit 13, thereby facilitating the replacement and maintenance of the first battery unit 21. The second battery unit 22 may be arranged on a side of the hollow cavity of the third box unit 14 away from the frame unit 11, thereby further lowering the center of gravity, thereby improving the stability of the vehicle 60.The second battery unit 22 is detachably connected to the third box unit 14, which is convenient for replacement and maintenance of the second battery unit 22. The shortest distance between the center of gravity of the first battery unit 21 and the frame unit 11 is a first set value, and the shortest distance between the center of gravity of the second battery unit 22 and the frame unit 11 is a second set value. In another embodiment, the first set value and the second set value can be equal. Thus, the first battery unit 21 and the second battery unit 22 are placed symmetrically. The symmetrical structure makes the weight distribution more uniform and also increases the stability of the battery box.

[0041] The water cooling component 40 can be arranged in the hollow cavity of the frame component 10, which helps to prevent the water cooling component 40 from being impacted by the outside and plays a certain protective role for the water cooling component 40. The water cooling component 40 and the power supply component 20 can be connected through a pipeline, and a cooling medium can be stored in the water cooling component 40, and the cooling medium can flow into the power supply component 20 through the pipeline, so that the cooling medium can absorb the heat released when the power supply component 20 is working, so that the power supply can work normally at a suitable temperature. The control component 30 can be arranged in the hollow cavity of the frame component 10, which helps to prevent the control component 30 from being impacted by the outside and plays a certain protective role for the control component 30. The control component 30 and the power supply component 20 can be electrically connected, so that the operation of the power supply component 20 can be regulated and controlled through the control component 30, and the precise operation of the power supply component 20 can be realized. At the same time, the working state of the power supply component 20 can also be monitored, and the operation of the power supply component 20 can be obtained in real time. The water cooling component 40 and the control component 30 can be electrically connected. When the operating temperature of the power supply component 20 is too high, the control component 30 can send a start-up command to the water cooling component 40 to make the water cooling component 40 work and cool down the power supply component 20, thereby ensuring the normal operation of the system.

This design can effectively utilize the bottom space of the vehicle 60, and also enhance the stability of the battery box installation. In addition, this design also makes the weight of the battery box evenly distributed below the beam 61, so that the center of gravity of the battery box is further lowered, and also makes the surface above the beam 61 relatively flat, which is convenient for the stable placement of goods.

This design may further lower the center of gravity of the battery box. The second battery unit 22 is disposed in the hollow cavity of the sixth box body 142, which is conducive to preventing the second battery unit 22 from being subjected to external impact and plays a certain protective role for the second battery unit 22.
