Description

Technical Field

[0001] The present invention relates to the technical field of power transmission for new energy vehicles, and in particular to a multi-physical quantity fusion intelligent cable for new energy vehicles. Background Art

[0002] As a key component of the new energy vehicle power system, cables for new energy vehicles are primarily responsible for power transmission. They stably and efficiently transmit the electricity generated by the battery pack to all parts of the vehicle, ensuring the proper operation of the new energy vehicle. New energy vehicle cables operate under various operating conditions, generating internal temperatures that directly affect the cable's service life. Current cable testing methods rely solely on external testing units. This method is highly limited and cannot directly monitor the internal temperature and operating conditions of the cable, resulting in inaccurate monitoring data and an inability to accurately and intuitively display the specific location of faults. Furthermore, the cable's overall compressive strength is also low. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the current cable detection method is very limited, the monitoring data is not accurate enough, and the specific location of the fault cannot be accurately and intuitively displayed. At the same time, the compressive strength of the entire cable is not high.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a multi-physical quantity fusion intelligent cable for new energy vehicles, including a copper conductor, a silicone rubber insulation layer is provided on the outside of the copper conductor, a tinned braided shielding layer is covered on the outside of the silicone rubber insulation layer, an aluminum-plastic composite tape shielding layer is covered on the outside of the tinned braided shielding layer, and a silicone rubber sheath is covered on the outside of the aluminum-plastic composite tape shielding layer. A distributed optical fiber temperature measurement module is provided between the aluminum-plastic composite tape shielding layer and the tinned braided shielding layer, and a magnetically controlled temperature conduction positioning device is provided on the distributed optical fiber temperature measurement module.

[0005] The distributed optical fiber temperature measurement module includes a chip temperature measurement module and a transmission optical fiber fixed on a magnetically controlled temperature conducting positioning device.

[0006] The magnetically controlled temperature-conducting positioning device includes a metal temperature-conducting ring fixedly sleeved on the outside of the tinned braided shielding layer, an integral metal inner assembly plate fixed on the side wall of the metal temperature-conducting ring, a metal outer assembly plate elastically assembled on the side wall of the metal temperature-conducting ring, a first electromagnet fixed on the side wall of the metal inner assembly plate, and a second electromagnet installed on the side wall of the metal outer assembly plate.

[0007] The metal inner assembly plate is provided with a circular fixing groove for fixing the first electromagnet, and the chip temperature measurement module is fixed on the periphery of the circular fixing groove.

[0008] Arc-shaped wire grooves communicating with the inside of the circular fixing groove are provided on both side walls of the metal inner assembly plate.

[0009] A flexible isolation strip is mounted on the outer side of the metal outer assembly plate.

[0010] The chip temperature measurement module is provided with lateral limiting notches on both sides that match the arc-shaped wire grooves.

[0011] A strip-shaped transition opening matched with the second electromagnet is provided on the side wall of the metal outer assembly plate.

[0012] The side wall of the metal outer assembly plate is provided with a lateral limiting plate of an integral structure bent toward the outside of the second electromagnet.

[0013] The connecting end of the metal temperature conducting ring and the metal inner assembly plate is provided with an arc-shaped limiting block of an integral structure.

[0014] The beneficial effects of the present invention are:

[0015] (1) The multi-physical quantity fusion intelligent cable for new energy vehicles of the present invention has a distributed optical fiber temperature measurement module directly installed inside the cable to monitor the operating status of the cable in real time and improve the accuracy of the monitoring data;

[0016] (2) The distributed optical fiber temperature measurement module consists of a chip temperature measurement module and a transmission optical fiber, and integrates a communication module to achieve remote data transmission and improve the functionality of the cable;

[0017] (3) A magnetically controlled temperature positioning device is provided on the distributed optical fiber temperature measurement module. Once a temperature abnormality occurs, the magnetically controlled temperature positioning device will be automatically activated. Through local expansion, the fault location will be displayed more intuitively. At the same time, the enlarged gap will be used to form a heat dissipation channel inside the cable, thereby enhancing the heat dissipation effect of the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0027] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The multi-physical quantity fusion intelligent cable for new energy vehicles shown in the figure includes a copper conductor 1, a silicone rubber insulation layer 2 is provided on the outside of the copper conductor 1, a tinned braided shielding layer 3 is covered on the outside of the silicone rubber insulation layer 2, an aluminum-plastic composite tape shielding layer 4 is covered on the outside of the tinned braided shielding layer 3, and a silicone rubber sheath 5 is covered on the outside of the aluminum-plastic composite tape shielding layer 4. A distributed optical fiber temperature measurement module 6 is provided between the aluminum-plastic composite tape shielding layer 4 and the tinned braided shielding layer 3, and a magnetically controlled temperature conduction positioning device 7 is provided on the distributed optical fiber temperature measurement module 6.

[0029] In order to coordinate temperature measurement and information transmission, the distributed optical fiber temperature measurement module 6 includes a chip temperature measurement module 61 fixed on the magnetically controlled temperature conducting positioning device 7 and a transmission optical fiber 62 .

[0030] The chip temperature measurement module 61 is a temperature sensor, which is an existing temperature measurement technology and is used to monitor the internal operating status of the cable in real time. At the same time, the transmission optical fiber can realize the remote transmission of data.

[0031] In order to cooperate with the magnetic control adjustment gap, the magnetic control temperature conductive positioning device 7 includes a metal temperature conductive ring 71 fixedly mounted on the outside of the tinned braided shielding layer 3, an integral metal inner assembly plate 72 fixed on the side wall of the metal temperature conductive ring 71, a metal outer assembly plate 73 elastically assembled on the side wall of the metal temperature conductive ring 71, a first electromagnet 74 fixed on the side wall of the metal inner assembly plate 72 and a second electromagnet 75 installed on the side wall of the metal outer assembly plate 73.

[0032] When the temperature at a local location is abnormal, the metal thermal conductive ring 71 guides the temperature to the metal inner assembly plate 72. The chip temperature measurement module 61 at this location detects the abnormally high temperature and activates the first electromagnet 74 and the second electromagnet 75 on a circle of the metal thermal conductive ring 71. The first electromagnet 74 and the second electromagnet 75 repel each other due to like charges. The second electromagnet 75 drives the metal outer assembly plate 73 to squeeze outward, forming an outward-protruding channel at this location. At other locations of the cable, the first electromagnet 74 and the second electromagnet 75 on one side are activated to form a horizontal channel. At this time, the high temperature inside the cable will quickly flow out. A centrifugal fan can also be set at the end of the cable in advance to increase the air circulation speed.

[0033] For lateral fixation, the metal inner assembly plate 72 has a circular fixing groove 721 for fixing the first electromagnet 74 , and the chip temperature measurement module 61 is fixedly mounted on the outer periphery of the circular fixing groove 721 .

[0034] In order to match the lateral straight line and improve durability, arc-shaped wire grooves 722 connected to the inside of the circular fixing groove 721 are provided on both side walls of the metal inner assembly plate 72 .

[0035] The lateral connection line of the chip temperature measurement module 61 passes through the arc-shaped wire groove 722 and is connected to the control end of the first electromagnet 74 for controlling the opening and closing of the first electromagnet 74 and the second electromagnet 75.

[0036] In order to avoid collision and friction between the first electromagnet 74 and the second electromagnet 75 , a flexible isolation strip 731 is mounted on the outer surface of the metal outer assembly plate 73 .

[0037] To facilitate installation and transition, lateral limiting notches that match the arc-shaped wire grooves 722 are opened on both sides of the chip temperature measurement module 61.

[0038] The connection line of the chip temperature measurement module 61 is led outward through the lateral limiting notch.

[0039] In order to cooperate with the assembly of the delivery optical fiber 62, a strip-shaped transition opening 732 that cooperates with the second electromagnet 75 is opened on the side wall of the metal outer assembly plate 73.

[0040] The delivery optical fiber 62 passes through the strip-shaped transition opening 732 and is not affected by the flipping of the metal outer assembly plate 73 .

[0041] In order to prevent the second electromagnet 75 from being displaced during squeezing and to improve the lateral limiting capability, the side wall of the metal outer assembly plate 73 has an integral lateral limiting plate 733 that is bent toward the outside of the second electromagnet 75 .

[0042] In order to ensure the fit of the contact surface, the connection ends of the metal thermal conductive ring 71 and the metal inner assembly plate 72 are provided with an integrated arc-shaped limit block.

[0043] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
