Description

Technical Field

[0001] This utility model relates to the field of truck battery pack testing technology, specifically a battery testing fixture. Background Technology

[0002] Truck battery pack testing fixtures are specialized testing equipment designed for truck battery packs composed of multiple series / parallel batteries (common voltages include 24V, 48V, and 72V). Their core functions include simultaneously monitoring the consistency, total capacity, charge / discharge balance, and individual cell faults of the entire battery pack. They are adapted to the characteristics of truck battery packs, such as "multiple series connections, high voltage, and high current." For example, handheld portable battery pack testers can simultaneously measure the total voltage of the entire pack plus the voltage and internal resistance of each individual cell, quickly assess battery pack consistency (individual cell voltage difference), support cold start current (CCA), charging system compatibility testing, and data storage (multiple battery test records) and simple report generation.

[0003] In daily use, the test lines of existing battery testing fixtures are generally directly exposed to the outside. When not in use, they lack protection and are easily damaged by external pressure. Furthermore, the accumulated test lines are prone to tangling or even knotting, affecting testing efficiency. Therefore, a new battery testing fixture is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a battery testing fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A battery testing fixture includes a battery testing equipment body. The bottom end of the battery testing equipment body has symmetrically arranged first threaded holes. A first connector is threaded into the interior of the first threaded holes. A test line is fixedly connected to the bottom end of the first connector. A second connector is fixedly connected to the end of the test line away from the first connector. An alligator clip is threaded to the end of the second connector away from the test line. A limit hole is formed on the inner side of the alligator clip. A protective shell is provided on the rear side of the battery testing equipment body. Four connecting rods, symmetrically arranged vertically inside the protective shell, are fixedly connected to the rear side of the battery testing equipment body. The rear side of the connecting rods is fixed... A metal limiting plate located inside the protective shell is connected to the battery testing device. A rubber pad located inside the protective shell is fixedly connected to the rear side of the metal limiting plate. A magnet layer located behind the rubber pad is fixedly connected inside the protective shell, and the magnet layer is magnetically connected to the metal limiting plate. Four wire winders arranged symmetrically in an upper and lower position are fixedly connected to the rear side of the battery testing device body, and the wire winders are located inside the protective shell. A second threaded hole is opened on the rear side of the battery testing device body, which is symmetrically arranged between the wire winders. An elastic wire harness clamp located between two second threaded holes is fixedly connected to the rear side of the battery testing device body. A limiting rod arranged symmetrically is fixedly connected to the rear side of the protective shell.

[0007] Preferably, the connecting rod, metal limiting plate, rubber pad and magnet layer are grouped together, and there are four groups in total. The connecting rod, metal limiting plate, rubber pad and magnet layer are arranged symmetrically on the left and right sides at the edge inside the protective shell.

[0008] Preferably, the shape of the internal hole of the protective shell matches the shape of the metal limiting plate, both being cylindrical, and the diameter of the internal hole of the protective shell matches the diameter of the metal limiting plate.

[0009] Preferably, the inner shape and size of the first threaded hole and the second threaded hole are matched, and the inner shape and size of the first threaded hole and the second threaded hole are matched with the shape and size of the threaded portion of the first connector and the second connector.

[0010] Preferably, the inner diameter of the limiting hole is greater than the diameter of the limiting rod at its smallest point, and the inner diameter of the limiting hole is less than the diameter of the limiting rod at its largest point.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, by setting components such as the second connector, protective shell, connecting rod, metal limiting plate, wire winder, second threaded hole and elastic wire harness clamp, the test wire can be separated from the battery testing equipment body for independent storage and protection. This effectively avoids the phenomenon of the test wire getting tangled due to external pressure, which affects the testing efficiency. This solves the problem that in the daily use of existing battery testing fixtures, the test wires of portable testing equipment are generally directly exposed to the outside. When not in use, they lack protection and are easily damaged by external pressure. Furthermore, the accumulated test wires are prone to tangling or even knotting, which affects the testing efficiency.

[0013] 2. In this utility model, the protective shell and the battery testing equipment body can be quickly fixed together by the rubber pad and the magnetic layer, making it more convenient to use. At the same time, the magnetic layer is protected to prevent the metal limiting plate from damaging the magnetic layer. The limiting rod and the limiting hole can quickly fix the disassembled alligator clips to prevent them from being lost and affecting the next use. Attached Figure Description

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] A battery testing fixture includes a battery testing equipment body 1. The bottom end of the battery testing equipment body 1 has symmetrically arranged first threaded holes 2. A first connector 3 is threaded into the first threaded holes 2. A test line 4 is fixedly connected to the bottom end of the first connector 3. A second connector 5 is fixedly connected to the end of the test line 4 away from the first connector 3. An alligator clip 6 is threaded to the end of the second connector 5 away from the test line 4. A limit hole 7 is provided on the inner side of the alligator clip 6. A protective shell 8 is provided on the rear side of the battery testing equipment body 1. Four connecting rods 9, symmetrically arranged vertically, are fixedly connected to the rear side of the battery testing equipment body 1 inside the protective shell 8. The rear side of the connecting rods 9 is fixedly connected to a device located inside the protective shell 8. The battery testing device 1 has a metal limiting plate 10. A rubber pad 11 is fixedly connected to the rear side of the metal limiting plate 10 and located inside the protective shell 8. A magnet layer 12 is fixedly connected to the rear side of the rubber pad 11 inside the protective shell 8, and the magnet layer 12 is magnetically connected to the metal limiting plate 10. Four wire winders 13 are fixedly connected to the rear side of the battery testing device body 1 and are arranged symmetrically. The wire winders 13 are located inside the protective shell 8. A second threaded hole 14 is opened on the rear side of the battery testing device body 1 and is arranged symmetrically between the wire winders 13. An elastic wire harness clamp 15 is fixedly connected to the rear side of the battery testing device body 1 and is located between two second threaded holes 14. A limiting rod 16 is fixedly connected to the rear side of the protective shell 8 and is arranged symmetrically.

[0025] The connecting rod 9, metal limiting plate 10, rubber pad 11, and magnet layer 12 form a group, with a total of four groups. These four groups are symmetrically arranged on the left and right sides of the inner edge of the protective shell 8. Through multiple sets of limiting connection structures, the connection strength between the protective shell 8 and the battery testing equipment body 1 can be significantly enhanced. The shape of the internal holes of the protective shell 8 matches the shape of the metal limiting plate 10, both being cylindrical. The diameter of the internal holes of the protective shell 8 matches the diameter of the metal limiting plate 10, allowing for greater stability. The installation and removal of the protective shell 8 are facilitated to prevent the protective shell 8 from shaking after installation, which would affect the connection strength. The inner shape and size of the first threaded hole 2 and the second threaded hole 14 are matched, and the inner shape and size of the first threaded hole 2 and the second threaded hole 14 are matched with the shape and size of the threaded head of the first connector 3 and the second connector 5, which facilitates the fixing of one end of the detection line 4 and makes it convenient for the detection line 4 to be wound. The inner diameter of the limiting hole 7 is larger than the minimum diameter of the limiting rod 16, and the inner diameter of the limiting hole 7 is smaller than the maximum diameter of the limiting rod 16.

[0026] Workflow: When using a battery testing fixture, first rotate the first connector 3 to separate the test line 4 from the battery testing equipment body 1. Then rotate the alligator clip 6 to separate the alligator clip 6 from the second connector 5. Next, press the alligator clip 6 to clamp the limiting rod 16 through the limiting hole 7, thus fixing the alligator clip 6. Then pull the protective shell 8 backward to remove it. Next, insert the first connector 3 into the second threaded hole 14 and rotate to connect it. Then, hold the test line 4 and pass it through the upper and lower winding devices 13 on the same side. The detection line 4 is wound around. After winding, the excess detection line 4 near the second connector 5 is inserted into the slot on the same side of the elastic wire harness clamp 15. The other set of detection lines 4 is fixed in the same way. Then, the metal limiting plate 10 and the rubber pad 11 on the connecting rod 9 are reinserted into the protective shell 8. The protective shell 8 and the battery testing equipment body 1 are connected and fixed by the magnet layer 12 and the metal limiting plate 10. The rubber pad 11 is thin and will not affect the magnetic force of the magnet layer 12. It only plays a buffering role and protects the magnet layer 12.
