Description

Technical Field

[0001] This utility model relates to the field of train technology, specifically to a battery pack direction detection tool. Background Technology

[0002] Existing battery boxes consist of a box body and multiple battery packs installed inside the box body. The positive and negative terminals of adjacent battery packs are connected by conductive plates. The number of battery packs is generally a dozen or several dozen. Battery packs are easily installed backwards during installation. Therefore, after installation, the position of the positive and negative terminals of each battery pack needs to be checked one by one, which is tedious and reduces production costs. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects of the prior art in that the battery pack is easy to install backwards and the inspection is relatively laborious, so as to provide a fast battery pack orientation detection fixture.

[0004] Therefore, this utility model provides a battery pack orientation detection fixture, including a mounting plate and orientation detection components. At least one row of orientation detection components is mounted on the mounting plate, and multiple orientation detection components in each row are spaced apart along the length of the mounting plate. The multiple orientation detection components are correspondingly arranged with multiple battery packs in the battery box. The orientation detection components include: a circuit board with a first light-emitting diode and a second light-emitting diode arranged in parallel and installed in opposite directions, the first light-emitting diode and the second light-emitting diode emitting different colors; and two conductive probe components mounted on both sides of the circuit board and electrically connected to the circuit board, the two conductive probe components being used to contact the positive and negative terminals of the battery packs respectively.

[0005] The circuit board is connected to the conductive probe assembly via a wire assembly. The wire assembly includes a wire and a first terminal lug and a second terminal lug respectively disposed at both ends of the wire. The second terminal lug is fixedly connected to the terminal post of the mounting plate by a screw.

[0006] The conductive probe assembly includes: a first nut for pressing the first terminal lug against the top surface of the mounting plate; a sleeve extending through the mounting plate, the sleeve having external threads and its top threadedly connected to the first nut; a second nut threadedly connected to the sleeve and fixed to the back of the mounting plate; and a conductive probe extending out of the sleeve for corresponding contact with the positive and negative terminals of the battery pack.

[0007] The mounting plate is formed with elongated holes extending along its length for the sleeve to move.

[0008] The mounting plate is provided with indicator marks for indicating the detection direction.

[0009] The mounting plate is made of acrylic sheet.

[0010] The technical solution of this utility model has the following advantages:

[0011] 1. The battery pack orientation detection fixture provided by this utility model allows for the following process: During testing, a mounting plate is placed above the battery box, and multiple orientation detection components on the mounting plate are correspondingly set with multiple battery packs inside the battery box. The two conductive probe components of the orientation detection components are used to abut against the positive and negative terminals of the battery packs. The circuit board has a first light-emitting diode and a second light-emitting diode connected in parallel and installed in opposite directions. The first and second light-emitting diodes emit different colors, which allows for a one-time and intuitive determination of whether the positive and negative terminals of each battery pack are installed incorrectly by observing the light emission color of the diodes. This greatly improves the detection efficiency and reduces production costs.

[0012] 2. The battery pack orientation detection fixture provided by this utility model includes a conductive probe assembly comprising a first nut, a sleeve, a second nut, and a conductive probe. The first nut and the second nut cooperate to press and fix the sleeve onto the mounting plate, thus making assembly quick and convenient.

[0013] 3. The battery pack orientation detection fixture provided by this utility model has an elongated hole formed on the mounting plate that extends along its length and allows the sleeve to move. This allows the sleeve to move accordingly to the actual positions of the positive and negative terminals of the battery pack, and then be fixed to the mounting plate by the first nut and the second nut, making it more convenient to use.

[0014] 4. The battery pack orientation detection fixture provided by this utility model has an acrylic plate as the mounting plate, and the mounting plate is provided with indicator marks for indicating the detection direction. This ensures that the fixture is not installed incorrectly during testing, and the transparent acrylic plate facilitates the alignment of the conductive probe with the positive and negative terminals of the battery pack.

[0027] Example

[0028] This embodiment provides a battery pack orientation detection fixture, such as... Figure 1 and Figure 4 As shown, it includes a mounting plate 1 and two rows of direction detection components 2.

[0029] Two rows of direction detection components 2 are mounted on the mounting plate 1, with multiple direction detection components 2 in each row distributed at intervals along the length of the mounting plate 1. Each of the multiple direction detection components 2 corresponds to a multiple battery pack 4 within the battery box 3. It should be noted that the number of rows of direction detection components 2 can be flexibly selected according to actual needs.

[0030] Orientation detection component 2, such as Figure 3 and Figure 6 As shown, the system includes a circuit board 5 and two conductive probe assemblies 8. The circuit board 5 has a first light-emitting diode 6 and a second light-emitting diode 7 connected in parallel and mounted in opposite directions. The first light-emitting diode 6 and the second light-emitting diode 7 emit different colors. Figure 1 and Figure 2 As shown, two conductive probe assemblies 8 are mounted on both sides of the circuit board 5 and electrically connected to the circuit board 5. The two conductive probe assemblies 8 are used to contact the positive and negative terminals of the battery pack 4 respectively. Figure 5 As shown, the conductive probe assembly 8 includes: a first nut 14, which presses the first terminal lug 11 against the top surface of the mounting plate 1; a sleeve 15, which penetrates the mounting plate 1 and has external threads, with its top threadedly connected to the first nut 14; a second nut 16, which is threadedly connected to the sleeve 15 and fixed to the back of the mounting plate 1; and a conductive probe 17, which extends out of the sleeve 15 and is used to abut against the positive and negative terminals of the battery pack 4. The circuit board 5 is connected to the conductive probe assembly 8 via a wire assembly, which includes a wire 9 and a first terminal lug 11 and a second terminal lug 12 respectively disposed at both ends of the wire 9. The second terminal lug 12 is fixedly connected to the terminal post 13 of the mounting plate 1 by a screw 10.

[0031] like Figure 4 As shown, the mounting plate 1 has an elongated hole 18 extending along its length and allowing the sleeve 15 to move. The mounting plate 1 is provided with an indicator mark 19 for indicating the detection direction. In this embodiment, the mounting plate 1 is an acrylic plate.

[0032] The battery pack orientation detection fixture provided by this utility model allows for the following process: During testing, a mounting plate 1 is placed above a battery box 3. Multiple orientation detection components 2 on the mounting plate 1 are correspondingly arranged with multiple battery packs 4 inside the battery box 3. Two conductive probe components 8 of the orientation detection components 2 are used to abut against the positive and negative terminals of the battery packs 4. The circuit board 5 has a first light-emitting diode 6 and a second light-emitting diode 7 arranged in parallel and installed in opposite directions. The first light-emitting diode 6 and the second light-emitting diode 7 emit different colors. This allows for a one-time and intuitive determination of whether the positive and negative terminals of each battery pack are installed incorrectly by observing the light emission color of the diodes, greatly improving detection efficiency and reducing production costs.
