Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sampling line tooling for battery pack testing, specifically a sampling line tooling for battery pack testing. Background Technology
[0002] Battery pack testing and sampling line fixtures are key equipment for ensuring battery safety and performance. They are mainly used to collect core parameters such as voltage and temperature of individual cells and to achieve status monitoring and fault early warning through the battery management system (BMS). Its technical features include high-precision sampling, anti-interference design and integrated layout to ensure the accuracy and stability of data transmission.
[0003] In existing technologies, the sampling lines are mostly manually plugged and unplugged one by one, which is not only inefficient, but also prone to poor connection or misalignment due to operational errors when dealing with multi-interface battery packs, affecting the accuracy of the test results. Utility Model Content
[0004] The purpose of this utility model is to provide a sampling line tooling for battery pack testing, which solves the problem that in the existing technology, the sampling lines are mostly manually inserted and unplugged one by one, which is not only inefficient, but also prone to poor connection or misalignment due to operational errors when dealing with multi-interface battery packs, thus affecting the accuracy of the test results.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a pressure sampling line tooling for battery pack testing, including a placement base, in which several battery packs are placed. An interface is installed on the upper surface of the battery pack. A bracket is fixedly installed on the upper surface of the placement base. A clamping mechanism is installed on the upper surface of the bracket. A pressure sampling line is installed on the clamping end of the clamping mechanism. The pressure sampling line extends to the bottom of the bracket and is inserted into the interface.
[0006] Furthermore, the clamping mechanism includes a fixed frame, which is fixedly installed on the upper surface of the bracket. A screw is rotatably connected inside the fixed frame, and one end of the screw is rotatably connected to the inside of the bracket. A throttle handle is fixedly installed at one end of the screw. A guide slide is fixedly installed on the inner top of the fixed frame, and the guide slide is distributed on both sides of the screw. One end of the guide slide is fixedly connected to the upper surface of the bracket. A lifting plate is threadedly connected to the outer surface of the screw, and both ends of the lifting plate are slidably connected to the outer surface of the guide slide.
[0007] Furthermore, mounting plates are fixedly installed at both ends of the lifting plate.
[0008] Furthermore, an electric push rod is fixedly installed on the upper surface of the mounting plate.
[0009] Furthermore, each of the electric push rods has a movable clamping plate fixedly installed at its output end.
[0010] Furthermore, a fixed clamping plate is fixedly installed on the upper surface of the mounting plate, and several pressure sampling lines are provided between the fixed clamping plate and the movable clamping plate. The connection ends of the pressure sampling lines are all plugged into the interface.
[0011] This utility model has the following beneficial effects: (1) This utility model places the sampling line between the movable clamping plate and the fixed clamping plate, and extends to the bottom of the bracket. The sampling line is firmly clamped between the two to ensure that the connection end of the sampling line is accurately aligned with the battery pack interface. Then, by rotating the throttle, the screw is driven to rotate, which drives the lifting plate to move up and down along the guide slide, thereby adjusting the overall height of the mounting plate, the fixed clamping plate and the movable clamping plate to adapt to the interface position of battery packs of different sizes. The lifting plate descends, so that the connection end of the sampling line is inserted into the battery pack interface, thus completing the electrical connection of all sampling lines and realizing voltage or signal acquisition. After the test is completed, the operation of the throttle is reversed to raise the mounting plate, thereby pulling all the sampling lines out of the interface. This avoids the need for manual installation and disassembly, and improves the overall work efficiency.
[0012] (2) This utility model uses an electric push rod, a movable clamping plate and a fixed clamping plate to clamp and fix multiple sampling lines, thereby avoiding the situation of messy entanglement when multiple sampling lines are used together.
[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-4 As shown, this utility model is a sampling line tooling for battery pack testing, including a placement seat 1, a plurality of battery packs 2 are placed inside the placement seat 1, an interface 201 is installed on the upper surface of the battery packs 2, a bracket 3 is fixedly installed on the upper surface of the placement seat 1, a clamping mechanism 4 is installed on the upper surface of the bracket 3, and sampling lines 5 are installed on the clamping ends of the clamping mechanism 4. The sampling lines 5 extend to the bottom of the bracket 3 and are inserted into the interface 201. Place the battery pack 2 to be tested inside the placement seat 1, ensuring that its interface 201 faces upwards, so as to facilitate the connection of the sampling line 5.
[0018] The clamping mechanism 4 includes a fixed frame 401, which is fixedly installed on the upper surface of the bracket 3. A screw 402 is rotatably connected inside the fixed frame 401. One end of the screw 402 is rotatably connected to the inside of the bracket 3. A throttle 403 is fixedly installed at one end of the screw 402. A guide slide rod 404 is fixedly installed on the inner top of the fixed frame 401. The guide slide rod 404 is distributed on both sides of the screw 402. One end of the guide slide rod 404 is fixedly connected to the upper surface of the bracket 3. A lifting plate 405 is threadedly connected to the outer surface of the screw 402. Both ends of the lifting plate 405 are slidably connected to the outer surface of the guide slide rod 404. Mounting plates 406 are fixedly installed at both ends of the lifting plate 405; Electric push rods 407 are fixedly installed on the upper surface of the mounting plate 406; The output end of the electric actuator 407 is fixedly equipped with a movable clamping plate 408; A fixed clamping plate 409 is fixedly installed on the upper surface of the mounting plate 406. Several pressure sampling lines 5 are provided between the fixed clamping plate 409 and the movable clamping plate 408. The connection ends of the pressure sampling lines 5 are all plugged into the interface 201. The sampling line 5 is placed between the movable clamping plate 408 and the fixed clamping plate 409, extending below the bracket 3, and securely clamped between them, ensuring that the connection end of the sampling line 5 is precisely aligned with the battery pack interface 201. Then, by rotating the handle 403, the screw 402 is driven to rotate, causing the lifting plate 405 to move up and down along the guide slide 404, thereby adjusting the overall height of the mounting plate 406, the fixed clamping plate 409, and the movable clamping plate 408 to adapt to the interface position of battery packs of different sizes. The lifting plate 405 descends, allowing the connection end of the sampling line 5 to be inserted into the battery pack interface 201, thus completing the electrical connection of all sampling lines 5 and realizing voltage or signal acquisition. After the test is completed, the operation of the handle 403 is reversed to raise the mounting plate 406, thereby pulling all the sampling lines 5 out of the interface 201, avoiding the need for manual installation and disassembly, and improving the overall work efficiency.
[0019] When using it, first place the battery pack 2 to be tested inside the placement seat 1, ensuring that its interface 201 faces upwards, so as to facilitate the connection of the sampling line 5. Then, the sampling line 5 is placed between the movable clamping plate 408 and the fixed clamping plate 409, extending to the bottom of the bracket 3, and the sampling line 5 is firmly clamped between them, ensuring that the connection end of the sampling line 5 is precisely aligned with the battery pack interface 201. Then, by rotating the handle 403, the screw 402 is driven to rotate, which drives the lifting plate 405 to move up and down along the guide slide 404, thereby adjusting the overall height of the mounting plate 406, the fixed clamping plate 409, and the movable clamping plate 408 to adapt to the interface position of battery packs of different sizes. The lifting plate 405 descends, allowing the connection end of the sampling line 5 to be inserted into the battery pack interface 201, thus completing the electrical connection of all sampling lines 5 and realizing voltage or signal acquisition. After the test is completed, the operation of the handle 403 is reversed to raise the mounting plate 406, thereby pulling all the sampling lines 5 out of the interface 201, avoiding the need for manual installation and disassembly, and improving the overall work efficiency.
