Description

Technical Field

[0001] This invention relates to the field of new energy vehicle battery technology, and more specifically, to a rear-mounted battery swapping compartment for pickup trucks. Background Technology

[0002] In the current development of new energy commercial vehicles, the layout of their power battery compartments is mostly based on the chassis arrangement. Specifically, the battery compartment is precisely installed in the lower area of ​​the vehicle chassis. This specific layout inevitably compresses the space under the vehicle in actual operation, directly resulting in a significant reduction in the vehicle's ground clearance. When the vehicle is traveling on unpaved roads, roads full of potholes, and other complex road conditions, the battery compartment located under the chassis is highly susceptible to collisions and scrapes with road obstacles. These collisions and scrapes not only cause direct and serious damage to the battery pack but also greatly restrict the vehicle's passability, making it difficult for the vehicle to meet the actual needs of complex working conditions such as engineering transportation, mining operations, and rural logistics, thus greatly limiting the vehicle's application range and efficiency in complex operating scenarios.

[0003] Meanwhile, the battery swapping structure used in traditional chassis-type battery compartments is highly complex, and its swapping methods are mostly limited to overall hoisting or fixed installation. This swapping mode has significant efficiency shortcomings, with a long swapping process that fails to meet the demands of efficient operation. Furthermore, the battery pack's cooling system is highly integrated with the chassis structure, which greatly reduces the effectiveness of thermal management. In actual operation, this can easily lead to a series of problems such as excessive battery temperature differences and uneven heat dissipation. These problems not only significantly shorten battery life but also pose serious safety risks, threatening the stable operation of the vehicle and operational safety. Summary of the Invention

[0004] Based on the aforementioned deficiencies in the existing technology, this invention proposes a rear-mounted battery swapping compartment for pickup trucks, aiming to solve the technical problems of poor vehicle passability, inconvenient battery swapping, and low thermal management efficiency.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The rear-mounted battery swapping compartment for pickup trucks in this invention is located between the front cab and the cargo box. Compared to a chassis-mounted battery compartment, it does not reduce the vehicle's ground clearance, thus avoiding issues with poor vehicle passability. Secondly, multiple battery compartments are located on the left and right sides of the main battery swapping compartment. The battery pack is detachably installed within the battery compartment, and the battery pack can be replaced by opening the compartment door assembly without replacing the entire battery swapping compartment, solving the inconvenience of battery swapping in existing technologies. Furthermore, because it is a rear-mounted battery swapping compartment, the available space is much larger than that of a chassis-mounted battery compartment. Therefore, upper and lower cooling plates are respectively provided on the upper and lower sides of the battery pack to cool and dissipate heat from both ends, enhancing heat dissipation and improving thermal management efficiency.

[0016] The rear-mounted battery swapping compartment for pickup trucks in this invention features battery guide rails on both the front and rear sides of the compartment. The battery pack is mounted on these guide rails, which guides the insertion and removal of the battery pack during replacement, facilitating connection and effectively preventing installation deviations, thus avoiding the phenomenon of one side of the battery pack being higher than the other after installation.

[0017] The cold plate lifting mechanism can simultaneously drive the upper and lower cooling plates to detach from or attach to the battery pack. Both the cold plate lifting mechanism and the door opening and closing mechanism are connected to the vehicle's main control system. The main control system controls the cold plate lifting mechanism and the door opening and closing mechanism to work together. When the door opening and closing mechanism drives the door assembly to open, the cold plate lifting mechanism drives the upper and lower cooling plates to detach from the battery pack at the same time, so that the door opening and the cooling plate movement are synchronized, effectively improving the battery swapping efficiency.

[0047] Preferably, the cold plate lifting mechanism further includes a first lifting limit seat 38 and a second lifting limit seat 41. The first lifting limit seat 38 is fixed to the front end and the top of the rear end of the main frame 9. The first lifting limit seat has a vertically opened upper cold plate lifting limit through hole 39.

[0048] In this embodiment, when the upper cooling plate 5 and the lower cooling plate 6 are attached to the battery pack 3, the push arm 19 is in a vertical state, the upper cooling plate lifting rod 26 is located at the lower end of the upper cooling plate lifting guide through hole 22 and the upper cooling plate lifting limit through hole 34, and the lower cooling plate lifting rod 27 is located at the upper end of the lower cooling plate lifting guide through hole 23 and the lower cooling plate lifting limit through hole 35. The output end of the cold plate lifting push rod 18 extends, driving the push arm 19 to rotate, the connecting rod 20 to move, and the push beam 21 to move horizontally away from the push arm mounting seat 28. The upper cold plate lifting rod 26 rises along the upper cold plate lifting guide through hole 22 and the upper cold plate lifting limit through hole 34, driving the upper cold plate connecting rod 24 and the upper cooling plate 5 to rise. The lower cold plate lifting rod 27 descends along the lower cold plate lifting guide through hole 23 and the lower cold plate lifting limit through hole 35, driving the lower cold plate connecting rod 25 and the lower cooling plate 6 to descend, so that the upper cooling plate 5 and the lower cooling plate 6 are detached from the battery pack 3, thereby facilitating the replacement of the battery pack 3. After the battery pack 3 is replaced, the output end of the cold plate lifting push rod 18 shortens and resets, so that the upper cooling plate 5 and the lower cooling plate 6 are in contact with the battery pack 3.

[0049] The rear-mounted battery swapping compartment of the pickup truck in this embodiment also includes a high-voltage compartment 50. The high-voltage compartment 50 is fixed inside the main body of the battery swapping compartment and located between the left and right battery compartments 4. Sockets 51 connected to the battery pack 3 are installed at both ends of the high-voltage compartment 50, and a circuit connected to the sockets 51 is provided inside the high-voltage compartment 50. The main pipeline 7 includes a main inlet pipe and a main outlet pipe, which are respectively located on the front and rear sides of the high-voltage compartment 50 and arranged in a U-shape. One end of the main inlet pipe and the main outlet pipe are closed, and the other end is connected to a pump body fixed to the vehicle body to form a circuit.

[0050] In this embodiment, both the cold plate lifting mechanism and the door opening and closing mechanism are connected to the vehicle's main control system. Specifically, the cold plate lifting push rod 18 and the door opening and closing push rod 16 are both connected to the vehicle's main control system, which controls the linkage between the cold plate lifting mechanism and the door opening and closing mechanism. Simultaneously, as the door opening and closing mechanism drives the door assembly to open, the cold plate lifting mechanism drives the upper cooling plate 5 and lower cooling plate 6 to detach from the battery pack 3. Conversely, as the door opening and closing mechanism drives the door assembly to close, the cold plate lifting mechanism drives the upper cooling plate 5 and lower cooling plate 6 to contact the battery pack 3. The door opening and cooling plate movement are synchronized, effectively improving battery swapping efficiency.

[0051] Specifically, the cold plate lifting push rod 18 and the hatch opening and closing push rod 16 adopt electric cylinders or electric push rods.
