Description

Technical Field

[0001] This utility model relates to the field of battery testing, and more specifically, to a multi-channel voltage testing device for high-speed train batteries. Background Technology

[0002] The battery in a high-speed train is a key component of the electric drive system, responsible for providing stable power support to the train. The working state of the battery directly affects the safety and performance of the train. When the battery is working, it is affected by external factors such as temperature, humidity and load to varying degrees. These factors may cause changes in the internal pressure of the battery. When the internal pressure of the battery is too high, it may cause the battery to swell, leak, or even cause serious safety accidents such as battery leakage or explosion. If the pressure is too low, it may cause the battery performance to deteriorate, resulting in insufficient power supply and affecting the operation of the train. The battery pressure measuring device plays a vital role in ensuring the safety and performance of the battery.

[0003] Currently, when testing the batteries of high-speed trains, operators need to use a multimeter to test each one individually. The existing technology has the following shortcomings and areas for improvement: (1) Existing multimeters only have a single testing channel and cannot simultaneously test multiple terminals of the battery pack in real time. Under busy maintenance schedules, the maintenance efficiency cannot meet production progress requirements. (2) Maintenance personnel need to record the measured data. Previously, this required two people to read and transcribe the data before filling it into the computer, which could not guarantee the accuracy and speed of data recording. Therefore, a multi-channel voltage testing device for high-speed train batteries should be proposed to solve the above problems. Utility Model Content

[0028] Please refer to Figure 1 and Figure 3 This embodiment proposes a multi-channel voltage testing device for a high-speed train battery, including a housing 1. The bottom of the housing 1 is provided with a monitoring component 2 for detecting the high-speed train battery. The top of the housing 1 is provided with an integrated component 3 for intuitively displaying monitoring data. The bottom of the housing 1 is provided with a protective component 4 for protecting the monitoring component 2. A starting component 5 for starting the entire device is provided on one side of the housing 1.

[0029] Please refer to Figure 2 , Figure 3 and Figure 7 The monitoring component 2 includes multiple sets of elastic telescopic pins 201 located at the bottom of the housing 1. These pins contact multiple terminals of the battery for monitoring. The pins extend through the housing 1 and into its interior, arranged in a crisscross pattern at the bottom of the housing 1 to prevent incorrect connections. One end of each pin is fixedly connected to a mounting base 202, which is bolted to the inner bottom wall of the housing 1. In use, the pins 201 are brought into contact with the battery terminals. The crisscross arrangement prevents incorrect connections, enabling the device to accurately collect various electrical signals from the battery. Significant improvements have been achieved in detection accuracy, the number of detection channels, data processing and transmission capabilities, and user-friendliness, providing a more robust technical guarantee for the safe operation of high-speed trains.

[0030] Please refer to Figure 2 , Figure 3 and Figure 6 The integrated component 3 includes a partition 301 fixedly connected to the bottom of the housing 1. A power supply 302 is fixedly installed inside the partition 301. The bottom of the power supply 302 is attached to the bottom of the housing 1. A power module 303 is installed on the top of the power supply 302. The power module 303 is fixedly connected to the partition 301 by bolts. A display 304 is bolted to the top of the housing 1. The display 304 is electrically connected to multiple sets of elastic telescopic pins 201 and the power supply 302. In use, the elastic telescopic pins 201 are connected to the EMU battery. The operator can intuitively see the monitoring data through the display 304 bolted to the top of the housing 1. The data collected by the elastic telescopic pins 201 can be quickly transmitted to the display 304 for display, reducing interference and delay in intermediate links, and facilitating the staff to obtain real-time status information of the battery in a timely manner. The power supply 302 is fixedly installed inside the partition 301, and its bottom is attached to the bottom of the housing, which can ensure the stability of the power supply 302 inside the housing.

[0031] Please refer to Figure 2 and Figure 5The protective component 4 includes a protective cover 401 located below the housing 1. Multiple sets of connecting blocks 402 are fixedly installed on the top of the inner wall of the protective cover 401. Magnets 403 are embedded inside the multiple sets of connecting blocks 402. Correspondingly, a groove is opened at the bottom of the housing 1. Magnets are also installed inside the groove. Multiple sets of silicone pads 404 are fixedly installed at the bottom inner wall of the protective cover 401. The positions of the multiple sets of silicone pads 404 correspond one-to-one with the positions of the multiple sets of elastic telescopic pins 201. When monitoring the EMU battery is required, the operator can simply remove the protective cover 401. After monitoring is completed, the protective cover 401 is installed on the bottom of the housing 1. Since the connecting block 402 has a magnet 403 embedded inside and a magnetic block is set inside the groove, according to the principle that like poles of magnet 403 repel and unlike poles attract, when the connecting block 402 is close to the groove, the magnet 403 and the magnetic block will generate a magnetic force that attracts each other. Under the action of the magnetic force, the protective cover 401 can be quickly and accurately adsorbed on the bottom of the housing 1, realizing the installation and fixation of the protective cover 401. When the monitoring device is subjected to external forces such as collisions and squeezing during transportation, installation or use, the silicone pad 404 can play a buffering role and protect the elastic telescopic pin 201 from damage.

[0032] Please refer to Figure 4 The starting assembly 5 includes a mounting plate 501 located on one side of the housing 1. A switch button 502 is fixedly mounted on the outer wall of the mounting plate 501. The switch button 502 is electrically connected to the display 304. A dust cover 503, made of transparent acrylic sheet, is rotatably connected to the top of the mounting plate 501. Operators can start the entire device for monitoring using the start button. The rotatable design of the dust cover 503 makes its opening and closing simple and quick, and also prevents accidental activation of the switch button 502, thus avoiding electric shock to operators and potential accidents.

[0033] Please refer to Figure 1 A charging port 6 is provided on one side wall of the housing 1. The charging port 6 is electrically connected to the power supply 302 and the power module 303 and is located on the side of the switch.

The USB interface 7 is electrically connected to the display 304, and a USB flash drive or external hard drive can be inserted to facilitate the transfer of data from the display 304, which greatly improves the efficiency of data interaction.

[0035] Please refer to Figure 6An audible and visual alarm 8 is bolted to the outer wall of the housing 1, and is located below the display 304. When the operator is viewing the monitoring data on the display 304, the alarm is easily obscured by their line of sight. When an abnormality occurs in the monitoring device, the alarm can quickly issue a warning signal, providing timely assistance.

[0036] In some other embodiments: the audible and visual alarm 8 is located on each side of the device, making it easier for operators to notice the alarm information when viewing the monitoring data on the display 304, thus reminding the operators to pay attention.

[0037] Specifically, when using the multi-channel voltage testing device for the battery of this EMU, please refer to: Figure 4 The operator presses the switch button 502 on the start-up component 5 to start the entire pressure testing device. At this time, if... Figure 2 , Figure 3 and Figure 6 As shown, the display 304 in the device will light up, ready to receive and display electrical signal data from the battery. Multiple flexible telescopic pins 201 are then connected to the various terminals of the train's battery. The cross-arranged pin design effectively avoids the risk of misconnection, thus ensuring the accuracy of the measurement data. The flexible telescopic pins 201 begin collecting various electrical signal data from the battery and transmit the data to the display 304, which will display the data in real time. The operator can intuitively view the battery's status information. When the device needs charging, the operator can insert the compatible charger into the charging port 6 on one side of the housing 1. If it is necessary to save or transfer the monitoring data, a USB flash drive or external hard drive can be inserted through the USB interface 7 to export the data to other devices for subsequent data analysis and archiving. If the device malfunctions or malfunctions, the audible and visual alarm 8 will issue a warning signal to promptly remind the operator.
