Buffer rubber blocks are fixedly installed on the top and bottom outer walls of the protective shell, and the top outer wall of the buffer rubber block is of a serrated structure. A socket is fixedly installed on one outer wall of the protective shell, and the socket is of a trapezoidal structure.

[0004] The above-mentioned prior art solutions have the following deficiencies: This technical solution completes the splicing and assembly fixation through a series of fixed mechanisms such as fixing bolts, but this splicing and assembly structure is relatively cumbersome, bringing inconvenience to the staff. At the same time, during the driving process of the vehicle, the battery cells vibrate unstably due to the influence of road conditions, resulting in abnormal acquisition of the battery voltage and low acquisition accuracy. Therefore, it is necessary to design an acquisition board of a combined battery management system to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an acquisition board of a combined battery management system to solve the problem that the acquisition board of the battery management system is relatively cumbersome during assembly and splicing in the above-mentioned background art.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A combined battery management system acquisition board, including a battery acquisition board body connected inside a battery acquisition board protection frame. At the four corners of the top of the battery acquisition board protection frame, first connection blocks are respectively fixedly connected. At the four corners of the bottom of the battery acquisition board protection frame, second connection blocks are respectively fixedly connected, and the bottom ends of the second connection blocks are all connected with connection plates. A splicing and fixing mechanism is arranged inside each of the first connection blocks, and the splicing and fixing mechanism includes a receiving groove, a damping telescopic rod, a guiding groove, a guiding wheel, a limiting block, and a movable block.

[0007] As a further description of the above technical solution, the receiving groove is arranged inside the first connection block. On both sides inside the receiving groove, damping telescopic rods are connected, and springs are sleeved on the outer sides of the damping telescopic rods. The inner sides of the damping telescopic rods are all connected with limiting blocks, and the bottom ends of the limiting blocks are all connected with guiding wheels. Guiding grooves are arranged at the bottom ends inside the first connection blocks, and the guiding grooves are all slidably connected with the guiding wheels. The bottom end of the connection plate is connected with a movable block.

[0008] As a further description of the above technical solution, the inclination angles of the inclined surfaces of the movable block and the limiting block are equal, and the two are in sliding contact.

[0009] As a further description of the above technical solution, the shape of the movable block is trapezoidal, and its two sides are respectively in contact with the inner sides of the limiting blocks.

[0010] As a further description of the above technical solution, clamping seats are fixedly connected to both sides of the first connection block, and one end of each clamping seat is connected with a movable rod. One end of the clamping seat on one side of the movable rod is connected with a connecting rod, and the connecting rod and the movable rod are connected by a pressing rod. The inner side of the connecting rod is connected with a clamping plate, and a damping protection pad is connected to the bottom of the clamping plate.

[0011] As a further description of the above technical solution, there are four clamping seats, which are respectively located on both sides of the top of the battery acquisition board protection frame.

[0012] Adopting the technical solutions provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0013] When assembling and splicing two groups of battery acquisition board protection frames and battery acquisition board bodies, the second connection block drives the connection plate and the movable block at the bottom to insert into the inside of the receiving groove. The two sides of the movable block are in contact and slide with the inner sides of the limiting blocks, and under the elastic action of the spring, the inner sides of the limiting blocks can be clamped on the top of the movable block, making the connection between the second connection block and the first connection block tighter and more stable, and further making the battery acquisition board body less likely to shake and loosen during driving and working.

[0014] By installing the clamping seat, during the splicing process of the two groups of battery collection board protection frames, the upper-layer battery collection board protection frame will press down the pressing rod. Under the action of the hinge, it can drive the connecting rod to tilt up, and further drive the clamping plate to press down on the surface of the battery collection board body to further limit and fix the battery collection board body, preventing the battery collection board body from loosening and having poor contact due to road conditions during the driving of the vehicle, effectively improving the use value of the battery collection board body. At the same time, the force applied under the linkage during the splicing of the battery collection board protection frame drives the clamping plate to limit and clamp the battery collection board body, which can reduce a certain mechanical structure operation cost.

And the splicing and fixing mechanism 7 includes a receiving groove 701, a damping telescopic rod 702, a guiding groove 703, a guiding wheel 704, a limiting block 705, and a movable block 706. The receiving groove 701 is arranged inside the first connection block 2. Both sides inside the receiving groove 701 are connected with damping telescopic rods 702. And springs are sleeved on the outer sides of the damping telescopic rods 702. The inner sides of the damping telescopic rods 702 are all connected with limiting blocks 705. And the bottom ends of the limiting blocks 705 are all connected with guiding wheels 704. Guiding grooves 703 are arranged at the bottom ends inside the first connection blocks 2. And the guiding grooves 703 are all slidably connected with the guiding wheels 704. The bottom end of the connection plate 6 is connected with a movable block 706.

The shape of the movable block 706 is trapezoidal, and its two sides are respectively in contact with the inner sides of the limiting blocks 705.

[0026] In this embodiment, when it is necessary to splice and assemble two groups of battery collection board protection frames 1, the second connection block 5 drives the connection plate 6 and the movable block 706 at the bottom to directly snap into the inside of the first connection block 2. During the downward sliding of the movable block 706, it comes into contact and slides with the limiting blocks 705 on both sides. And under the elastic action of the spring, the inner sides of the limiting blocks 705 can be clamped on the top of the movable block 706, making the connection between the second connection block 5 and the first connection block 2 more tight and stable. Thus, the work process of rapid splicing and assembly is completed, bringing convenience to the staff.
