Description

Technical Field

[0002] The cable layout of new energy vehicles is the core link of the vehicle electrical system design, which directly affects the safety, electromagnetic compatibility (EMC) and reliability of the vehicle. Since new energy vehicles (especially pure electric and fuel cell vehicles) involve high-voltage systems (usually 300V-800V), their cable layout must comply with strict technical specifications and safety standards; The cables in the car are divided into high-voltage lines and low-voltage lines. For high-voltage lines, not only the stability of the line connection must be ensured, but also the potential safety hazards caused by line leakage must be prevented. For low-voltage circuits, a reasonable spatial layout is required to ensure that the layout is stable and reliable, and to avoid damage during daily use. However, the existing automotive cable laying method is to integrate the cables together through a cable harness mechanism, and use the frame structure or designed protective covers to stabilize the cable installation. This method only optimizes the stability of the cables, and has a low improvement in safety. In the event of a vehicle collision or other emergency, the automotive cables and batteries are prone to leakage or short circuit when in contact with the frame, posing a safety hazard to the people in the car.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0016] like Figures 1 to 6 As shown; An intelligent automobile cable laying device includes a wiring board 1, the wiring board 1 is a T-shaped plate structure, the wider end of the wiring board 1 is arranged corresponding to the electrode of the automobile battery, the narrower end of the wiring board 1 is attached to the battery surface, a protection module 2 is fixed at the bottom side of the wiring board 1 corresponding to the battery electrode position, and a plurality of wire harness plates 3 arranged along the narrower end of the wiring board 1 are fixedly installed on the surface of the wiring board 1 by bolts; The protection module 2 includes a shell 201 fixed to the bottom side of the wiring board 1 by bolts, and the shell 201 is fixed with wiring terminals 202 on both sides, and the bottom of the shell 201 is formed with a second fixing seat 203, and the contact piece 204 in the wiring terminal 202 penetrates the shell 201 and extends to the inner side of the shell 201, and an insulating pad 205 is installed on the inner bottom side of the shell 201. The surface of the insulating pad 205 is provided with a connecting block 206, and the two sides of the connecting block 206 are in contact with the contact piece 204, and the top of the connecting block 206 is fixed with a pull rod 207. The inner wall of the shell 201 Arc extinguishers 208 are fixed on both sides, and a fixing plate 209 fixed in the housing 201 is arranged above the arc extinguisher 208. The pull rod 207 passes through the fixing plate 209. A spring 210 is sleeved on the top outer wall of the pull rod 207. One end of the spring 210 abuts against the surface of the fixing plate 209, and the other end abuts against the top of the pull rod 207. A clamping claw 211 is fixed on the top inner wall of the housing 201. The clamping claw 211 is engaged with the top of the pull rod 207. Electromagnets 212 are arranged on both sides of the bottom of the clamping claw 211. A reset hole 213 is provided starting from the middle of the top of the housing 201. In this embodiment: During installation, the wiring board 1 is arranged on the surface of the automobile battery, and the wiring board 1 is fixed above the battery compartment by bolts and the first fixing seat 102, so that the arrangement and installation of the wiring board 1 are completed. The two poles of the battery are connected to the wiring terminal 202 on one side, and the wiring terminal 202 on the other side is connected to the high-voltage cable. The wiring terminal 202 is a clamping plate structure, and the cable is clamped and fixed by the screws on the top. The top of the protection module 2 is installed on the bottom side of the wiring board 1 by bolts, and the bottom is connected to the chassis structure of the vehicle by bolts and the second fixing seat 203. The low-voltage line in the car is usually used to power sensors and car machines. The low-voltage line is laid on the surface of the wiring board 1 and passes through the car body from the bottom of the car. The low-voltage line is pressed on the surface of the wiring board 1 by the wiring harness plate 3 to limit The electric motor 208 can detect the occurrence of a collision through various sensors on the vehicle body, and simultaneously send signals to the control module. The control module energizes the electromagnet 212 to generate a large magnetic force. The electromagnet 212 can adsorb the bottom end of the iron clamp 211 to deform it, and the bottom side of the clamp 211 opens outward, thereby releasing the top end of the pull rod 207. The pull rod 207 is pushed upward by the elastic force of the spring 210, driving the connecting block 206 to move upward, thereby disconnecting the two contact pieces 204. The arc extinguisher 208 can quickly eliminate the arc and avoid the arc generated at the moment of power failure. In this way, the battery power supply is cut off in time to avoid the occurrence of vehicle short circuit and leakage caused by collision.

[0017] More specifically: In an optional embodiment, a high-voltage wire groove 101 is provided on one side of the wiring board 1 close to the protection module 2 , and a T-shaped wire guard post 6 is provided at the high-voltage wire groove 101 , and the wire guard post 6 is fixed on the surface of the wiring board 1 .

[0018] In this embodiment: Since the battery compartment is arranged on the vehicle chassis, through this design, the automobile cables can be connected to the transformer module through the high-voltage wire duct 101. The high-voltage wire duct 101 constitutes a storage space for the cables to avoid wear at the cable bends. At the same time, the wire guard post 6 is arranged on the outside of the cable. The T-shaped wire guard post 6 divides the high-voltage wire duct 101 into two independent spaces, which is convenient for distinguishing the cables, and further protects the cables to prevent the vehicle chassis from deforming and damaging the cables during a vehicle collision.

[0019] In an optional embodiment, at least two groups of wire harness plates 3 are provided, and the wire harness plates 3 are evenly installed on the surface of the wiring board 1 .

[0020] In this embodiment: the wire harness plate 3 is used for harnessing low-voltage lines. The cables used by in-vehicle sensors and low-voltage electrical appliances for lighting are fixed to the surface of the wiring board 1 in this way. The wire harness plate 3 is a common splint structure, which is fixed and limited by bolts. The wire harness plate 3 is set in such a way that the cables are closely arranged along the wiring board 1 and is set on the vehicle chassis at the same time. This setting can prevent the cable layout from affecting other components in the vehicle.

[0021] Going further: In an optional embodiment, a cavity 4 is opened inside the wiring board 1, and the cavity 4 is filled with perfluorohexanone. A pressure sensor is arranged in the cavity 4, and the pressure sensor is connected to the control module, and the control module is connected to the electromagnet 212, and the control module is connected to the vehicle computer. A one-way valve is installed on the outer wall of the wiring board 1.

[0022] In this embodiment: when the vehicle collides and the wiring board 1 is deformed, the cavity 4 at the beginning of the wiring board 1 may be deformed due to the deformation. When the deformation is large, it will rupture, and the perfluoroacetone in the cavity 4 will overflow and fill the battery compartment. The battery is prevented from catching fire by the perfluoroacetone. At the same time, the pressure sensor in the cavity 4 detects the abnormal pressure change and transmits the signal to the control module. After receiving the signal, the control module starts the electromagnet 212 to achieve power-off protection.

[0023] It should be noted that: the present invention has two groups of terminal blocks 202, one of which is connected through an insulating pad 205, and the contact pieces 204 of the other group of terminal blocks 202 are directly connected. The cable connected through the insulating pad 205 is connected to the high-voltage circuit of the transformer module, and the cable directly connected through the contact piece 204 is connected to the low-voltage circuit of the transformer module. Through this design, the car battery can continuously provide low-voltage power to the vehicle, avoiding other systems in the vehicle from being unusable when the insulating pad 205 is disconnected, and the backup battery in the vehicle is also connected to the low-voltage circuit of the transformer module.

[0024] Going further: In an optional embodiment, a limiting groove 5 is provided on the bottom side of the wiring board 1 , and the limiting groove 5 corresponds to the car battery.

[0025] In the present embodiment: through this design, the wiring board 1 is made to fit the battery more closely, and the limiting groove 5 is arranged toward the automobile battery. When the battery compartment is deformed, the wiring board 1 which is in contact with the battery is also deformed to the same extent as the battery, that is, the point where the battery is deformed the most is also the point where the wiring board 1 of the present invention is deformed the most. The battery is more likely to be damaged and catch fire here. The wiring board 1 of the present invention is relatively weak at the beginning of the limiting groove 5, that is, the bottom side of the wiring board 1 is thinner, so that the perfluoroacetone in the wiring board 1 can enter the battery compartment more easily, and the battery can be fire-proofed and extinguished.

[0026] Going further: In an optional embodiment, a plurality of first fixing seats 102 are formed on the edge of the wiring board 1 , and the wiring board 1 is mounted on the vehicle frame via the first fixing seats 102 .

[0027] In this embodiment: through this design, the wiring board 1 is easy to install and fixed more stably and reliably.

[0028] A method for laying cables for an intelligent vehicle comprises the following steps: S1, connecting the automobile battery electrode to the connection terminal 202 on one side; S2, connecting the high voltage line to the wiring terminal 202 on the other side; S3, pass the high voltage line through the high voltage line slot 101 to connect to the transformer module, the transformer module is connected to the motor platform, wherein the transformer module has two lines, high voltage and low voltage, the high voltage line is connected to the connection block 206 through the contact piece 204, usually 400-800V, and the low voltage line is directly connected through the contact piece 204 in the terminal block 202, usually 100-400V; S4, install the low-voltage circuit in the vehicle in the harness plate 3. The low-voltage circuit is the circuit of the electronic components in the vehicle such as sensors, lighting, and vehicle computer systems, and is usually 12V; S5. Lay the wiring board 1 on the surface of the car battery, and firmly fix the wiring board 1 and the frame with bolts; the limiting groove 5 in the wiring board 1 matches the battery compartment, the limiting groove 5 fits the car battery, and the wall thickness of the wiring board 1 at the position of the limiting groove 5 is thinner.

[0029] S6. When the vehicle encounters an emergency, the protection module 2 disconnects the battery, the vehicle computer sends a signal to the control module, and the control module starts the electromagnet 212 to open the clamp 211, so that the spring 210 pushes the pull rod 207 and the connecting block 206 to move, so that the contact piece 204 is disconnected, thereby protecting the vehicle; since the car itself is equipped with a variety of detection radars to determine whether the vehicle has collided and the deployment of the airbag, this design associates the detection radar signal with the control module. When the detection radar identifies that the vehicle is in a collision state, the in-vehicle alarm system sends a signal to the control module; S7. When the wiring board 1 is damaged, the pressure sensor transmits a signal to the control module, and the control module starts the electromagnet 212 to disconnect the contact piece 204, and at the same time, the perfluorohexanone in the cavity 4 overflows into the battery compartment; in this design, the pressure sensor in the wiring board 1 monitors the pressure in the cavity 4 in real time. When the battery compartment is deformed due to a vehicle collision, the pressure in the cavity 4 will change suddenly due to the deformation of the cavity 4. The control module identifies and judges this sudden change signal and determines that a collision has occurred. The control module transmits the signal to the electromagnet 212 to enable the protection module 2 to operate. This judgment method is a dual judgment of interval and rate, that is, it not only identifies the pressure range, but also identifies the pressure change speed. In this way, slight changes in the pressure in the cavity 4 caused by temperature and normal vehicle driving bumps are eliminated, and the control module synchronously receives the alarm signal and the pressure sensor signal sent from the vehicle, that is, when the vehicle collides, any signal can enable the control module to start the protection module 2 to cut off the power.

[0030] In this embodiment: Since the high-voltage line voltage is relatively high and poses a greater threat to personnel, when the protection module 2 is powered off, the high-voltage line module in the transformer module is disconnected, that is, the high-voltage line connected by the contact piece 204 and the connecting block 206 in S3, and the low-voltage line is still connected. In this way, the working power of the motor is limited, and the vehicle is in a low-power state, thereby reducing the battery output load and the vehicle's working current, thereby reducing the possibility of battery heating and fire, and further improving the safety of the vehicle. The low-voltage line can also enable other functions in the vehicle to be used normally, avoiding the overall power failure and paralysis of the vehicle in the event of a collision.

[0031] Going further: In an optional embodiment, the motor platform includes a high-voltage motor platform and a low-voltage motor platform. An adapter module is connected between the transformer module and the motor platform. The adapter module is connected to the control module. When the control module receives a vehicle computer signal or a pressure sensor signal, the adapter module is connected to the low-voltage motor platform, and is connected to the high-voltage motor platform under normal conditions.

[0032] In this embodiment: through this design, the conversion module is an undervoltage release circuit breaker or contactor structure, the adapter module is connected to the output end of the transformer module, and when the high-voltage line is powered off, the conversion module automatically cuts off the part of the high-voltage line connected to the motor platform, that is, when the high-voltage line is powered off, the conversion module is automatically disconnected, thereby strengthening the protection of the motor, and preventing the voltage of the low-voltage line from being reversely energized to the protection module 2 through the high-voltage line, thereby reducing the occurrence of leakage.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
