Description

Technical Field

[0001] The present invention belongs to the technical field of power battery packs, and particularly relates to a quickly detachable and installable power battery for buses and its usage method. Background Art

[0002] In the current technical field of bus power batteries, traditional power battery installation methods often use fixed bolts or welding to fix battery cells in the battery pack and fix the battery pack inside the bus. Although this installation method ensures the stability and safety of the battery to a certain extent, there are many inconveniences in actual operation.

[0003] The traditional installation method makes the maintenance and replacement process of the battery pack cumbersome and time-consuming. When a certain battery cell in the battery pack fails and needs to be repaired or replaced, the staff needs to spend a lot of time and effort to disassemble the entire battery pack, find and replace the problematic battery cell, and then reassemble the battery pack. This not only increases the time and labor costs required for maintenance, but also may lead to a decline in the performance or damage of the battery pack due to improper operations during the disassembly and assembly process. Summary of the Invention

[0004] The purpose of the present invention is as follows: Through the quick assembly and disassembly between battery cell mechanisms, the replacement and maintenance of power battery cells become more convenient. Problematic power battery cells can be quickly located and replaced without disassembling the entire battery pack, thereby improving the efficiency of maintenance work. According to actual needs, the number and configuration of power battery cells can be quickly adjusted to adapt to different driving requirements and road conditions, which helps to optimize energy use and improve the operating efficiency of the bus. At the same time, through the battery general assembly mechanism, the battery general assembly mechanism and multiple battery cell mechanisms can be quickly installed and disassembled, making the maintenance of the power battery pack simpler and faster. When the battery pack needs to be repaired or replaced, the staff can quickly operate, reducing the time and labor costs required for maintenance, which is particularly important for buses that need to frequently replace the battery pack, can significantly improve the overall operating efficiency, facilitate regular inspection and maintenance of the battery pack, promptly discover and handle potential problems, and extend the battery service life.

[0018] Step 1: Disassembly and assembly of battery units: Between two adjacent power battery units, insert the two connecting plates on one power battery unit into the two positioning slot boxes on the other power battery unit. Then, control the connection drive motor on the other power battery unit to start, and drive the corresponding two connecting bidirectional threaded rods to rotate synchronously through two synchronous pulleys. Each connecting bidirectional threaded rod drives the corresponding two connecting transmission blocks to move relatively closer. Every two connecting transmission blocks drive the corresponding connecting transmission strip plates to move through the corresponding two connecting transmission rods, so that the two connecting transmission strip plates move relatively away from each other. Each connecting transmission strip plate drives the corresponding three insertion rods to insert into the corresponding connecting plate, thus completing the installation between the two power battery units. Install a new power battery unit onto the power battery units that have been assembled together, and repeat the above operation.

[0022] (1) In the present invention, when multiple battery unit mechanisms are fixedly installed inside the placement frame box, the base box is placed inside the installation frame plate. By controlling the start of the installation drive motor, the installation bidirectional threaded rod is driven to rotate, driving two installation drive blocks to move relatively closer. The two installation drive blocks drive two installation drive strip plates to move relatively away from each other through four installation drive rods, thereby driving two groups of installation connecting rods to be inserted into the inner wall of the installation frame plate respectively, realizing the fixed installation of the battery assembly mechanism and multiple battery unit mechanisms. Only by controlling the installation drive motor to reverse, finally driving the two groups of installation connecting rods to leave the installation frame plate, the battery assembly mechanism and multiple battery unit mechanisms can be disassembled. The battery assembly mechanism and multiple battery unit mechanisms can be quickly installed and disassembled, making the maintenance of the power battery pack simpler and faster. When the battery pack needs to be repaired or replaced, the staff can operate quickly, reducing the time and labor costs required for maintenance, which is particularly important for buses that need to frequently replace the battery pack, can significantly improve the overall operation efficiency, facilitate regular inspection and maintenance of the battery pack, promptly discover and handle potential problems, and extend the battery service life.

[0023] (2) In the present invention, between two adjacent power battery units, two connecting plates on one power battery unit are inserted into two positioning slot boxes on the other power battery unit. Then, the connection drive motor on the other power battery unit is controlled to start, and two corresponding connection bidirectional threaded rods are driven to rotate synchronously through two synchronous wheels. Each connection bidirectional threaded rod drives two corresponding connection drive blocks to move relatively closer. Every two connection drive blocks drive the corresponding connection drive strip plates to move through the corresponding two connection drive rods, causing the two connection drive strip plates to move relatively away from each other. Each connection drive strip plate drives three corresponding insertion rods to be inserted into the corresponding connection plate, thereby completing the installation between the two power battery units. To install a new power battery unit onto the power battery units that have been assembled together, the above operation can be repeated. Only by controlling the connection drive motor on one of the power battery units to reverse, finally driving the corresponding two groups of insertion rods to disengage from the corresponding two connection plates, the adjacent power battery unit can be removed. The rapid assembly and disassembly between multiple battery unit mechanisms make the replacement and maintenance of power battery units more convenient. The problematic power battery unit can be quickly located and replaced without disassembling the entire battery pack, thereby improving the efficiency of maintenance work. The number and configuration of power battery units can be quickly adjusted according to actual needs to adapt to different driving requirements and road conditions, which helps to optimize energy use and improve the operation efficiency of the bus.
