Description

Technical Field

[0001] This utility model relates to the field of cables, and in particular to a cable monitoring mechanism for electric vehicles with vibration sensing detection. Background Technology

[0002] With the development of new energy vehicles, the demand for and design of electric vehicle charging cables have also increased. Therefore, cable condition monitoring is an essential part of safety design. Monitoring requirements include: anti-theft, abnormal use, and breakage.

[0003] Existing cable monitoring typically involves checking the continuity of current, combined with visual observation by staff or video cameras to reduce anomalies. However, such devices are generally expensive and have high installation requirements. Utility Model Content

[0004] The main objective of this invention is to propose a cable monitoring mechanism for electric vehicles with vibration sensing detection.

[0005] To achieve the above objectives, this utility model proposes a cable monitoring mechanism for electric vehicles with vibration sensing detection, comprising:

[0006] The cable includes a plurality of charging cells, a plurality of data cells, and at least one optical fiber distributed along the length of the cable. The outer walls of the charging cells, data cells, and optical fiber are covered with a wrapping layer, and the wrapping layer is provided with a sheath layer.

[0007] The monitoring, analysis, and alarm device includes a signal transmitter and a signal collector. Two cables are provided, one end of which is connected to a charging station, and the other end has a connector. The cables include a first cable and a second cable.

[0008] One end of the first optical fiber of the first cable is connected to the signal transmitter, and the other end of the first optical fiber is connected to the second optical fiber of the second cable. The other end of the second optical fiber is connected to the signal acquisition device.

[0009] The monitoring, analysis, and alarm device is used to monitor the presence and wavelength of signals from the signal acquisition device and to determine the usage status of the cable.

[0010] In practical design, the signal transmitter can emit a single wavelength or a predetermined wavelength, and the signal received by the signal collector can determine the usage of the cable, thereby timely judging the status of the cable and reducing the risk of abnormal use or theft.

[0011] When the connector needs to be charged, it can emit a single wavelength. If the duration of the wavelength exceeds the predetermined time, it can alert the monitoring system or staff, thereby determining whether there is a problem with the charging cable, such as a faulty or damaged connector, and thus promptly assessing the usage status of the charging station.

[0012] Of course, it can also transmit wavelengths in different bands. When the attenuation, phase, wavelength, polarization, mode field distribution, and propagation time of the light wave change, the usage of the cable can be judged more accurately.

[0013] The essence of this monitoring mechanism is that when the fiber optic sensor is affected by external interference, some characteristics of the light transmitted in the fiber optic cable will change, thereby realizing the detection of the signal. The filling material and wrapping layer can prevent the fiber optic cable from being damaged by bending. Attached Figure Description

[0028] like Figures 1 to 4 As shown, a cable monitoring mechanism for electric vehicles with vibration sensing detection includes:

[0029] Cable 1, the cable 1 includes a plurality of charging cores 11, a plurality of data cores and at least one optical fiber distributed along the length of the cable 1, the outer walls of the charging cores 11, the data cores 12 and the optical fiber are covered with a wrapping layer 22, the wrapping layer 22 is provided with a sheath layer 23.

[0030] The monitoring and analysis alarm device 5 includes a signal transmitter 51 and a signal collector 52. Two cables 1 are provided, one end of which is connected to the charging station 31, and the other end is equipped with a connector 32. The cables 1 include a first cable 1 and a second cable 1.

[0031] One end of the first optical fiber 41 of the first cable 1 is connected to the signal transmitter 51, and the other end of the first optical fiber 41 is connected to the second optical fiber 42 of the second cable 1. The other end of the second optical fiber 42 is connected to the signal acquisition device 52.

[0032] The monitoring and analysis alarm device 5 is used to monitor the presence and wavelength of the signal from the signal acquisition device 52, and to determine the usage status of the cable.

[0033] In the actual design, the signal transmitter 51 can emit a single wavelength or emit a predetermined wavelength, and the signal received by the signal collector 52 can determine the usage status of the cable 1, thereby timely determining the status of the cable 1 and reducing the risk of abnormal use or theft.

[0034] When the connector 32 needs to be charged, it can emit a single wavelength. If the duration of the wavelength exceeds the predetermined time, it can alert the monitoring system or staff to determine whether there is a problem with the charging cable, such as abnormal or damaged connector, and thus promptly determine the usage status of the charging station 31.

[0035] Of course, it can also transmit wavelengths in different bands. When the attenuation, phase, wavelength, polarization, mode field distribution, and propagation time of the light wave change, the usage of the cable can be judged more accurately.

[0036] The essence of this monitoring mechanism is that when the fiber optic sensor is affected by external interference, some characteristics of the light transmitted in the fiber optic cable will change, thereby realizing signal detection. The filling material 21 and the wrapping layer 22 can prevent the fiber optic cable from being damaged due to bending of the cable 1.

[0037] Specifically, the signal transmitter 51 is an optical signal transmitter, and the signal collector 52 is an optical signal collector 52.

[0038] Specifically, the first optical fiber 41 and the second optical fiber 42 are connected by an optical coupler.

[0039] Specifically, when the optical signal of the signal collector 52 is disconnected, the monitoring and analysis alarm device 5 issues an early warning.

[0040] Among them, optical fiber, optical coupler, optical signal transmitter, and optical signal collector 52 are existing technologies.

[0041] Specifically, when the signal transmitter emits a predetermined wavelength, and the attenuation, phase, wavelength, polarization, mode field distribution, and propagation time of the light wave emitted by the signal collector 52 are less than a predetermined threshold, the monitoring and analysis alarm device 5 issues an early warning.

[0042] Specifically, the wrapping layer 22 is made of cotton paper or non-woven fabric. This design can improve the flexibility of the cable, enhance its abrasion resistance, and improve the bonding between the filler and the sheath layer 23.

[0043] In this embodiment of the utility model, a filler 21 is provided between the charging cell 11, the data cell 12 and the optical fiber. The wrapping layer 22 covers the outer peripheral wall of the filler 21. The filler 21 is PP rope, hemp or cotton thread, which avoids interference between the individual cores and provides support and insulation.

[0044] In this embodiment of the invention, the sheath layer is made of TPE material, also known as synthetic rubber or artificial rubber. Its products possess the excellent properties of traditional cross-linked vulcanized rubber, including high elasticity, aging resistance, and oil resistance, while also having the advantages of ordinary plastics, such as ease of processing and a wide range of processing methods. It can be produced using injection molding, extrusion, blow molding, and other processing methods.

[0045] like Figure 3 , Figure 4 As shown, attenuation generally occurs during transmission, and when the cable moves, the corresponding optical band will change at the predetermined position.

[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
