Description

Technical Field

[0001] This invention relates to the field of new energy BMS components, specifically to a BMS control board bracket structure that is easy to disassemble and assemble. Background Technology

[0002] New energy BMS is short for Battery Management System. It is one of the core components in new energy vehicles. The main functions of BMS include monitoring the battery status, such as voltage, current and temperature, controlling the charging and discharging process of the battery, ensuring that the battery operates within a safe operating range, balancing the performance and capacity of each individual cell in the battery pack, extending battery life, predicting and preventing battery failures, and improving the safety and reliability of the system.

[0003] As the management unit of the PACK system in new energy vehicles, the Battery Management System (BMS) plays a crucial role in the battery's lifespan, performance, and safety. Therefore, a reliable and stable BMS is essential for electric vehicles. Currently, BMS control boards typically require bracket structures for installation and fixation. Due to the different specifications of BMS systems, bracket structures of corresponding specifications are needed for installation, which is time-consuming, labor-intensive, and inefficient.

[0004] At present, a BMS control board bracket structure that is easy to disassemble and assemble is proposed to solve the problems mentioned in the background technology. Summary of the Invention

[0005] The purpose of this invention is to provide a BMS control board bracket structure that is easy to install and disassemble, solving the problem that current BMS systems require corresponding bracket structures for auxiliary installation due to their different specifications, which is time-consuming, labor-intensive, and inefficient. To achieve the above technical objective, the technical solution of this invention is as follows:

[0006] A BMS control board support structure that is easy to assemble and disassemble includes a BMS control board support housing, a moving device, and a locking device. The moving device is slidably connected to the BMS control board support housing, and the distance between the moving device and the BMS control board support housing can be adjusted. An upward-facing cylindrical protrusion is provided in the middle of the bottom of the BMS control board support housing and is located within the BMS control board support housing. A rotating gear block is rotatably connected to the upper end of the cylindrical protrusion. A first sliding groove and a second sliding groove are provided on the side wall of the cylindrical protrusion, and the first and second sliding grooves are connected. The first sliding groove is perpendicular to the bottom surface of the BMS control board support housing and extends through the upper end surface of the cylindrical protrusion. The second sliding groove is parallel to the bottom surface of the BMS control board support housing. The locking device is disposed within the first and second sliding grooves. The rotating gear block cooperates with the locking device and the moving device. The device is equipped with a pull ring, which is connected to the snap-fit ​​device. The connecting end of the pull ring extends into the BMS control board support housing and communicates with the second sliding groove. The pull ring drives the snap-fit ​​device to move, thereby controlling the movement of the rotating gear block. An adjustment device is installed on the moving device. The movement of the moving device synchronously drives the adjustment device to move. The adjustment device includes a fixed plate, a handle frame, a BMS control board snap-fit ​​frame, and a threaded rod. The threaded rod is fixedly connected to the moving device, and a threaded sleeve is threadedly connected to the threaded rod. A rotating connecting block is fixedly connected to the end of the threaded sleeve. The rotating connecting block is rotatably mounted on the fixed plate. The handle frame is connected to the rotating connecting block and is located on the side away from the moving device. The BMS control board snap-fit ​​frame is fixedly mounted on the top of the fixed plate. The adjustment device adjusts the position of the BMS control board snap-fit ​​frame according to different specifications of BMS control boards.

[0007] Further specified, the rotating connecting block is in the shape of a boss, including a protrusion and a connecting part, the fixing plate is provided with a through hole, the protrusion is rotatably disposed in the through hole, and the connecting part is fixedly connected to the end of the threaded sleeve.

[0008] Furthermore, mounting plates are provided at the four corners of the BMS control board support housing, and each mounting plate has several mounting holes.

[0009] Further defining the moving device, it includes a moving plate, a moving rod, and a sliding rod. There are four moving plates, located on the four sides of the BMS control board support housing. Each moving plate has a corresponding moving rod and sliding rod. The threaded rod is fixedly connected to the side wall of the moving plate away from the BMS control board support housing. One end of each moving rod and sliding rod is mounted on the moving plate, and the other end is located inside the BMS control board support housing. The moving rod has a rotating tooth groove and a sleeve groove on its side wall near the center of the BMS control board support housing. The moving rod on the left moving plate corresponds to the sliding rod on the right moving plate, and vice versa. The moving rod on the front moving plate corresponds to the sliding rod on the rear moving plate, and vice versa. The sliding rod is slidably connected to the sleeve groove on the corresponding moving rod. The moving rods and sliding rods on the left and right sides of the BMS control board support housing are located above the moving rods and sliding rods on the front and rear sides.

[0010] Further specified, the cylindrical protrusion is provided with a side protrusion, the rotating gear block is rotatably connected to the side protrusion, the bottom of the rotating gear block is also provided with several equidistant locking grooves, and a ring of gears is provided on the circumferential surface of the rotating gear block, the gears meshing with the rotating tooth grooves.

[0011] Further, it also includes a limiting device, which includes a limiting rod and a limiting sleeve. The limiting sleeve is fixedly installed on the side wall of the fixed plate near the moving plate. One end of the limiting rod is fixedly installed on the side wall of the moving plate, and the other end is slidably connected and snapped into the limiting sleeve.

[0012] Further specifying, the locking device includes a locking block, a spring, and a pull rope. The locking block is slidably connected within the first slide groove. The spring is located below the locking block, with one end connected to the locking block and the other end fixedly mounted on the bottom wall of the first slide groove. The pull rope is slidably connected within the second slide groove. One end of the pull rope passes through the spring and is connected to the locking block, while the other end is connected to the connecting end of the pull ring. The size of the locking block matches the size of the locking groove. When the locking block is inserted into the locking groove, the rotating gear block stops rotating.

[0013] The advantages of this invention over the current technology are as follows:

[0014] Pulling the pull ring causes the snap-fit ​​block to leave the snap-fit ​​slot, pushing the BMS control board snap-fit ​​bracket on one side of the pull ring until the inner wall of the BMS control board snap-fit ​​bracket is tightly against the side wall of the BMS control board, facilitating better fixation of the BMS control board. Rotating the handle bracket moves the fixing plate, which in turn moves the BMS control board snap-fit ​​bracket, adjusting its position. This allows for better adjustment of the BMS control board snap-fit ​​bracket's position as needed, enabling the bracket structure to effectively fix BMS control boards of different specifications and making the bracket structure flexible in use.

[0015] By rotating the handle bracket, the handle bracket drives the rotating connecting block to rotate, which in turn drives the threaded sleeve to rotate. The threaded sleeve moves on the threaded rod, synchronously driving the fixed plate to move. The fixed plate then drives the BMS control board mounting bracket to move, adjusting the position of the BMS control board mounting bracket. This allows for better adjustment of the BMS control board mounting bracket position as needed, enabling the bracket structure to better fix BMS control boards of different specifications, thus making the bracket structure flexible in use.
