Description

[0003] As a key component of the battery thermal management system, the design and selection of the water cooling plate directly affects the performance and safety of the battery. Depending on the different battery module structures and cell arrangements, water cooling plates of different sizes, shapes or layouts are required to achieve the best heat exchange effect.

[0004] Assembling a water cooling plate into a battery module usually requires the following steps: S1. Determine the model and specifications of the water cooling plate to match the size and heat dissipation requirements of the battery module. S2. Design the flow channel of the water cooling plate to ensure that the coolant can flow evenly through the battery cells or modules to achieve effective heat exchange. S3. Fix the water cooling plate to the battery module, usually using welding, bonding or mechanical fixation to ensure good contact between the water cooling plate and the battery cells or modules. S4. Connect the water cooling plate to the battery management system (BMS) to monitor and regulate the flow and temperature of the coolant.

The variable pitch lead screw is configured to be connected to the variable pitch support mechanism 30.

[0040] Among them, combined Figure 1 and Figure 2, the first positioning part 503 and the second positioning part 504 are respectively provided on both sides of the water-cooling plate 50, so it is necessary to design a variable pitch support mechanism 30 and a variable pitch positioning mechanism 40 for the first positioning part 503 and the second positioning part 504, and respectively set a second variable pitch drive source 20 to respectively position the first positioning part 503 and the second positioning part 504. It can be understood that the variable pitch screw of this embodiment is designed with multiple sections, namely the main variable pitch screw, the first variable pitch screw 103 and the second variable pitch screw 104, the first variable pitch screw 103 and the second variable pitch screw 104 are respectively provided at both ends of the main variable pitch screw through a coupling, and the main variable pitch screw, the first variable pitch screw 103 and the second variable pitch screw 104 are on the same straight line, then the output end of the first variable pitch drive source 102 is connected to the first variable pitch screw 103 and the second variable pitch screw 104 through a transmission assembly (not shown in the figure).

[0041] Furthermore, the active mechanism 10 also includes at least one displacement measurement component. The displacement measurement component includes a magnetic scale arranged along the length direction of the main frame 101 and a reader arranged on the variable pitch support mechanism 30 or the variable pitch positioning mechanism 40. The reader senses the magnetic code on the magnetic scale. The displacement measurement component is used to record the front position of the variable pitch support mechanism 30 and the variable pitch positioning mechanism 40 to prevent position loss and facilitate electrical debugging.

[0042] Specifically corresponding to the first positioning portion 503 and the second positioning portion 504, the present embodiment is provided with a first displacement measuring assembly 105 and a second displacement measuring assembly 106. The magnetic scale is arranged along the length direction of the main frame 101, and preferably, the reading head is arranged at the variable distance support mechanism 30 and the variable distance positioning mechanism 40, so as to record the current position of the variable distance support mechanism 30 and the variable distance positioning mechanism 40.

[0043] In this embodiment, combined with Figure 7 and Figure 8 The variable pitch support mechanism 30 further includes a first base connected to the variable pitch lead screw. The first movable component is slidably connected to the first base. The second movable component is transmission-connected to the second variable pitch drive source 20. The first movable component and the second movable component can be connected.

[0044] Specifically, the second movable assembly includes a first Z-axis screw rod 301, a first connection seat fixedly connected to the first base, a second suction cup 302 fixedly connected to the first connection seat, and a first cylinder 305 installed on the first connection seat. The first movable assembly includes a second connection seat slidably connected to the first base, a water nozzle avoidance assembly 303 fixedly connected to the second connection seat, a first cam 304 disposed on the second connection seat and facing the first cylinder 305, a fixing member 306 disposed on one side of the second connection seat, and a second cam 307 disposed on the fixing member 306.

[0045] The water spout avoidance assembly 303 includes a first avoidance block and a second avoidance block stacked together, and the first avoidance block and the second avoidance block are both provided with a U-shaped notch, and the notch is arranged toward the first water spout 501 or the second water spout 502. It should be noted that, since the first avoidance block needs to contact the water cooling plate 50, the material of the first avoidance block is an insulating material such as plastic. The material of the second avoidance block can be a metal material such as iron, so as to withstand a higher load and improve the strength and durability of the water spout avoidance assembly 303.

[0046] Furthermore, the first movable assembly further includes a first guide rail lock 308, which is disposed on a side of the second connection seat away from the faucet avoidance assembly 303. When the first guide rail lock 308 is ventilated, it is in an open state, and the variable distance support mechanism 30 can move; when the first guide rail lock 308 is de-vented, the position of the variable distance support mechanism 30 is fixed.

[0047] Furthermore, the second movable component also includes a third displacement measuring component 309 disposed on a side of the first base away from the first movable component. The third displacement measuring component 309 includes a magnetic scale disposed along the length direction of the first base and a reader disposed on one side of the first connecting base. When the second movable component moves, the reader senses the magnetic code on the magnetic scale.

[0048] In this embodiment, combined with Figures 9 to 11 The variable pitch positioning mechanism 40 further includes a second base. The third movable assembly is mounted on the second base. The fourth movable assembly is mounted on the second base and is transmission-connected to the second variable pitch driving source 20. The third movable assembly and the fourth movable assembly can be connected.

[0049] Specifically, the fourth movable assembly includes a second Z-axis screw rod 401, a third connection seat slidably connected to the second base, a second cylinder 402 disposed on the third connection seat, and a second follower 403 connected to the action end of the second cylinder 402. The third movable assembly includes a fourth connection seat slidably connected to the second base, a third cam 404 disposed on the fourth connection seat and close to the second follower 403, a fourth cylinder 411 disposed on one side of the fourth connection seat, a third follower 413 connected to the action end of the fourth cylinder 411 and facing the second cam 307, a fifth cylinder 412 disposed on the fourth connection seat, a third cylinder 405 connected to the action end of the fifth cylinder 412, and a positioning block 406 connected to the action end of the third cylinder 405. The positioning block 406 is used to position the end surface of the water-cooling plate 50.

[0050] Furthermore, the third movable assembly further comprises a second rail lock 407, which is arranged on a side of the fourth connection seat away from the third cylinder 405. When the second rail lock 407 is ventilated, it is in an open state, and the third movable assembly can move; when the second rail lock 407 is de-vented, the position of the third movable assembly is fixed.

[0051] The variable pitch positioning mechanism 40 further includes a third guide rail lock 414, which is disposed on a side of the second base away from the third movable assembly and the fourth movable assembly.

The fourth displacement measuring assembly 408 includes a magnetic scale disposed along the length direction of the second base and a reader disposed on one side of the fourth connecting base. When the fourth movable assembly moves, the reader senses the magnetic code on the magnetic scale.

[0053] It should be noted that, when changing the type, the variable distance support mechanism 30 and the variable distance positioning mechanism 40 move in the second horizontal direction by sharing a second variable distance driving source 20, and when the variable distance support mechanism 30 and the variable distance positioning mechanism 40 move in the first horizontal direction, the variable distance support mechanism 30 and the variable distance positioning mechanism 40 will also move in the second horizontal direction. When the second variable distance driving source 20 is started alone, the variable distance support mechanism 30 and the variable distance positioning mechanism 40 will also move in the second horizontal direction. Therefore, when the first variable distance driving source 102 and the second variable distance driving source 20 are started, the variable distance support mechanism 30 and the variable distance positioning mechanism 40 will move in the second horizontal direction. Based on this working condition, the first displacement measuring component 105, the second displacement measuring component 106, the third displacement measuring component 309 and the fourth displacement measuring component 408 are designed to record the current positions of the variable distance support mechanism 30 and the variable distance positioning mechanism 40.

Figure 6 As shown, the first synchronous wheel 201, the second synchronous wheel 202, the third synchronous wheel 203, the fifth synchronous wheel 409 and the fourth synchronous wheel 310 are tensioned. The output end of the second variable pitch driving source 20 is connected to the second synchronous wheel 202, and the second synchronous wheel 202 is used as a driving wheel, and the second synchronous wheel 202, the third synchronous wheel 203, the fourth synchronous wheel 310 and the fifth synchronous wheel 409 are used as driven wheels, and power is transmitted through the synchronous belt 204.

[0055] Further, two first clamping wheels 205 are arranged at the second synchronous wheel 202, and the two first clamping wheels 205 are symmetrically arranged about the second synchronous wheel 202. Two second clamping wheels 311 are arranged at the fourth synchronous wheel 310, and the two second clamping wheels 311 are symmetrically arranged about the fourth synchronous wheel 310. Two third clamping wheels 410 are arranged at the fifth synchronous wheel 409, and the two third clamping wheels 410 are symmetrically arranged about the fifth synchronous wheel 409. The first clamping wheel 205, the second clamping wheel 311 and the third clamping wheel 410 can apply a certain pressure to the synchronous belt 204 to ensure that the synchronous belt 204 maintains an appropriate tension during operation, which helps to reduce the vibration and noise of the synchronous belt 204 and improve the transmission efficiency.

[0058] Specifically, the fourth cylinder 411 pushes the third follower 413 to insert into the second cam 307, and the third movable component of the variable pitch positioning mechanism 40 is connected to the variable pitch support mechanism 30. At the same time, the third guide rail lock 414 is ventilated and opened, and the first variable pitch drive source 102 is started. The output end of the first variable pitch drive source 102 rotates the variable pitch support mechanism 30 and the variable pitch positioning mechanism 40 to move to the first specified position along the first horizontal direction. The third guide rail lock 414 is de-energized to lock the variable pitch positioning mechanism 40.

[0060] Specifically, the first cylinder 305 pushes the first follower 312 to insert into the first cam 304, and the first movable assembly is connected to the second movable assembly. The first guide rail lock 308 is opened for ventilation, and the second variable pitch drive source 20 is started. The output end of the second variable pitch drive source 20 rotates, driving the first movable assembly and the second movable assembly to move to the second designated position along the second horizontal direction. The first guide rail lock 308 is shut off to lock the first movable assembly. The action end of the first cylinder 305 retracts, driving the first follower 312 to retract, and then the first follower 312 and the first cam 304 are separated, and then the first movable assembly and the second movable assembly are separated.
