Description

Technical Field

[0001] The present invention belongs to the technical field of in-vehicle cable laying, and particularly relates to an intelligent vehicle cable laying device and a laying method. Background Art

[0002] The cable laying of new energy vehicles is a core link in the design of the vehicle's electrical system, directly affecting the vehicle's safety, electromagnetic compatibility (EMC), and reliability. Since new energy vehicles (especially pure electric and fuel cell vehicles) involve high-voltage systems (usually 300V - 800V), their cable laying needs to follow strict technical specifications and safety standards;

[0003] The cables in the vehicle are divided into high-voltage lines and low-voltage lines. For high-voltage lines, not only the stability of the line connection needs to be ensured, but also the safety hazards caused by external leakage of the line need to be prevented. For low-voltage circuits, a reasonable spatial layout is required to make their laying stable and reliable, and to avoid damage during daily use;

[0004] However, the existing vehicle cable laying methods integrate the cables through a bundling mechanism and use the vehicle frame structure or design a protective sleeve to install the cables stably. 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 emergencies, when the vehicle cables and the battery come into contact with the vehicle frame, leakage or short circuit is likely to occur, posing a safety hazard to the vehicle occupants.

[0005] To solve the above problems, an intelligent vehicle cable laying device and a laying method are proposed in this application. Summary of the Invention

[0008] The protection module includes a housing fixed to the bottom side of the wiring board by bolts. Wiring terminals are fixed on both sides of the housing. A second fixing seat is formed at the bottom of the housing. The contact piece in the wiring terminal penetrates the housing and extends to the inner side of the housing. An insulating backing plate is installed on the inner bottom side of the housing. Connection blocks are arranged on the surface of the insulating backing plate. Both sides of the connection block are in contact with the contact piece. A pull rod is fixed to the top of the connection block. Arc extinguishers are fixed to both sides of the inner wall of the housing. Above the arc extinguishers, there is a fixing plate fixed in the housing. The pull rod penetrates the fixing plate. A spring is sleeved on the outer side wall of the top of the pull rod. One end of the spring abuts against the surface of the fixing plate, and the other end abuts against the top end of the pull rod. Claws are fixed to the inner top wall of the housing. The claws are engaged with the top end of the pull rod. Electromagnets are arranged on both sides at the bottom of the claws. A reset hole is formed in the middle of the top end of the housing.

[0009] As an optimization of an intelligent vehicle cable laying device according to the present invention, a high-voltage wire groove is formed on one side of the wiring board close to the protection module. A wire protection column with a T-shaped structure is arranged at the high-voltage wire groove. The wire protection column is fixed on the surface of the wiring board.

[0010] As an optimization of an intelligent vehicle cable laying device according to the present invention, at least two sets of wire bundling plates are provided. The wire bundling plates are evenly installed on the surface of the wiring board.

[0011] As an optimization of an intelligent vehicle cable laying device according to the present invention, a cavity is formed inside the wiring board. The cavity is filled with perfluoromethylcyclohexanone. A pressure sensor is arranged in the cavity. The pressure sensor is connected to a control module. The control module is connected to the electromagnet. The control module is connected to the vehicle computer. A one-way valve is installed on the outer side wall of the wiring board.

[0012] As an optimization of an intelligent vehicle cable laying device according to the present invention, a limiting groove is formed on the bottom side of the wiring board. The limiting groove corresponds to the vehicle battery.

[0013] As an optimization of an intelligent vehicle cable laying device according to the present invention, a plurality of first fixing seats are formed at the edge of the wiring board. The wiring board is installed on the vehicle frame through the first fixing seats.

[0014] An intelligent vehicle cable laying method includes the following steps.

[0015] S1. Connect the vehicle battery electrode to one of the wiring terminals.

[0016] S2. Connect the high-voltage line to the other wiring terminal.

[0017] S3. Pass the high-voltage line through the high-voltage cable trough and connect it to the voltage transformation module. The voltage transformation module has two lines, a high-voltage line and a low-voltage line. The high-voltage line is connected through a contact piece and a connection block, and the low-voltage line is directly connected through the contact piece in the terminal block. The voltage transformation module is connected to the motor platform;

[0022] As an optimization of the intelligent vehicle cable laying method of the present invention, the motor platform includes a high-voltage motor platform and a low-voltage motor platform. A transfer module is connected between the voltage transformation module and the motor platform. The transfer module is connected to the control module. When the control module receives a signal from the vehicle computer or the pressure sensor, the transfer module accesses the low-voltage motor platform, and under normal conditions, it accesses the high-voltage motor platform.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] The wiring mechanism of the present invention has a protection module. The protection module is arranged between the battery and the voltage transformation module. When an accident occurs, the control module activates the electromagnet. The electromagnet adsorbs the tip of the jaw to make it open, thereby releasing the pull rod. The pull rod is driven by the spring to disconnect the contact piece and the connection block, disconnecting the power supply of the high-voltage circuit of the voltage transformation module, preventing the battery from leaking or short-circuiting. When the battery compartment undergoes a large deformation that may cause a fire, since the wiring board is arranged on the surface of the battery, it will also deform. At this time, the perfluoromethylcyclohexanone in the wiring board overflows to protect the battery, avoiding or slowing down the occurrence of the battery fire, thereby protecting the vehicle and the passengers in the vehicle.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0034] As Figures 1 to 6 shown;

[0035] An intelligent vehicle cable laying device includes a wiring board 1. The wiring board 1 is in a T-shaped plate structure. The wider end of the wiring board 1 is arranged corresponding to the electrode of the vehicle battery, and the narrower end of the wiring board 1 is attached to the battery surface. A protection module 2 is fixed at the position corresponding to the battery electrode on the bottom side of the wiring board 1. A plurality of wire bundling boards 3 arranged along the narrower end of the wiring board 1 are fixedly installed on the surface of the wiring board 1 by bolts;

[0036] The protection module 2 includes a housing 201 fixed to the bottom side of the wiring board 1 by bolts. Wiring terminals 202 are fixed on both sides of the housing 201. A second fixing base 203 is formed at the bottom of the housing 201. The contact piece 204 in the wiring terminal 202 penetrates through the housing 201 and extends to the inner side of the housing 201. An insulating backing plate 205 is installed on the inner bottom side of the housing 201. Connection blocks 206 are arranged on the surface of the insulating backing plate 205. Both sides of the connection block 206 are in contact with the contact piece 204. A pull rod 207 is fixed to the top of the connection block 206. Arc extinguishers 208 are fixed to both sides of the inner wall of the housing 201. Above the arc extinguishers 208, there is a fixing plate 209 fixed in the housing 201. The pull rod 207 penetrates through the fixing plate 209. A spring 210 is sleeved on the outer wall of the top 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 end of the pull rod 207. Claw jaws 211 are fixed to the inner top wall of the housing 201. The claw jaws 211 are engaged with the top end of the pull rod 207. Electromagnets 212 are arranged on both sides of the bottom of the claw jaws 211. A reset hole 213 is formed in the middle of the top end of the housing 201;

[0037] In this embodiment: When the present invention is installed, the wiring board 1 is arranged on the surface of the automotive battery, and the wiring board 1 is fixed above the battery compartment by bolts and the first fixing base 102, completing the setting and installation of the wiring board 1. The two poles of the battery are connected to the wiring terminals 202 on one side, and the wiring terminals 202 on the other side are connected to the high-voltage cable. The wiring terminals 202 are of a clamping plate structure, and the cable is clamped and fixed by the screws at 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 base 203. The low-voltage lines inside the vehicle usually supply power to sensors and the car radio. The low-voltage lines are laid on the surface of the wiring board 1 and pass through the vehicle body from the bottom inside the vehicle. The low-voltage lines are pressed on the surface of the wiring board 1 by the wire bundling plate 3 for positioning, and at the same time, it can avoid the situation of the lines being bent during layout. When the vehicle collides, the car radio can identify the occurrence of the collision accident through various sensors on the vehicle body and simultaneously send a signal to the control module. The control module energizes the electromagnets 212 to generate a large magnetic force. The electromagnets 212 can adsorb the bottom end of the iron claw jaws 211, causing them to deform. The bottom side of the claw jaws 211 opens outward, thus releasing the top end of the pull rod 207. The pull rod 207 is quickly pushed upward by the elastic force of the spring 210, driving the connection block 206 to move upward, so that the two contact pieces 204 are disconnected. The arc extinguishers 208 can quickly eliminate the arc, avoiding the generation of arc at the moment of power-off. By this method, the battery power supply is cut off in time to avoid the occurrence of vehicle short circuit and electric leakage caused by the collision.

[0038] Furthermore:

[0039] In an alternative embodiment, a high-voltage wire trough 101 is formed on one side of the wiring board 1 close to the protection module 2, and a wire protection post 6 with a T-shaped structure is provided at the high-voltage wire trough 101. The wire protection post 6 is fixed on the surface of the wiring board 1.

[0040] In this embodiment: Since the battery compartment is arranged at the vehicle chassis, through this design, the automotive cable can be connected to the voltage transformation module through the high-voltage wire trough 101. The high-voltage wire trough 101 forms a storage space for the cable, avoiding abrasion at the bent part of the cable. At the same time, the wire protection post 6 is arranged outside the cable. The wire protection post 6 with a T-shaped structure divides the high-voltage wire trough 101 into two independent spaces, facilitating the distinction of cables and further protecting the cables to prevent the deformation of the vehicle chassis from damaging the cable during a vehicle collision.

[0041] In an alternative embodiment, at least two sets of wire bundling plates 3 are provided, and the wire bundling plates 3 are evenly installed on the surface of the wiring board 1.

[0042] In this embodiment: The wire bundling plate 3 is used for bundling low-voltage lines. The cables used by in-vehicle sensors and low-voltage electrical appliances such as lighting lamps are fixed on the surface of the wiring board 1 in this way. The wire bundling plate 3 is a common clamping plate structure and is fixed by bolts to fix and limit the cables. The arrangement of the wire bundling plate 3 makes the cables closely arranged along the wiring board 1 and is arranged on the vehicle chassis at the same time. This arrangement can prevent the cable layout from affecting other components in the vehicle.

[0043] Furthermore:

[0044] In an alternative embodiment, a cavity 4 is formed inside the wiring board 1. The cavity 4 is filled with perfluorohexanone. A pressure sensor is arranged in the cavity 4. The pressure sensor is connected to a control module, the control module is connected to an electromagnet 212, the control module is connected to a vehicle computer, and a one-way valve is installed on the outer side wall of the wiring board 1.

[0045] In this embodiment: When a vehicle collision occurs and the wiring board 1 is deformed, the cavity 4 initially formed in the wiring board 1 may be deformed due to the deformation. When the amount of deformation is large, it will crack, and the perfluoroacetone in the cavity 4 overflows to fill the battery compartment, preventing the battery from catching fire through perfluoroacetone. At the same time, the pressure sensor in the cavity 4 detects abnormal pressure changes and transmits the signal to the control module. After receiving the signal, the control module activates the electromagnet 212 to achieve power-off protection.

[0046] It should be noted that: There are two groups of terminal blocks 202 in the present invention. One group is connected through an insulating backing plate 205, and the contact pieces 204 of the other group of terminal blocks 202 are directly connected. The cables connected through the insulating backing plate 205 are connected to the high-voltage line of the voltage transformation module, and the cables directly connected through the contact pieces 204 are connected to the low-voltage line of the voltage transformation module. Through this design method, the vehicle battery can continuously supply low voltage to the vehicle, avoiding the situation that other systems in the vehicle cannot be used when the insulating backing plate 205 is disconnected, and the in-vehicle backup battery is also connected to the low-voltage line of the voltage transformation module.

[0047] Furthermore:

[0048] In an optional embodiment, a limiting groove 5 is formed on the bottom side of the wiring board 1, and the limiting groove 5 corresponds to the vehicle battery.

[0049] In this embodiment: Through this design, the wiring board 1 fits closer to the battery. The limiting groove 5 faces the vehicle battery. When the battery compartment is deformed, the wiring board 1 that fits the battery is also deformed, and the degree of deformation is the same as that of the battery. That is, the place where the battery has the largest deformation is also the place where the wiring board 1 of the present invention has the largest deformation. It is easier for the battery to be damaged and catch fire at this place. The position of the wiring board 1 where the limiting groove 5 starts is relatively weak, that is, the bottom side of the wiring board 1 is thinner, so that the perfluoroacetone in the wiring board 1 can more easily enter the battery compartment to carry out fire prevention and extinguishing treatment on the battery.

[0050] Furthermore:

[0051] 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 installed on the vehicle frame through the first fixing seats 102.

[0052] In this embodiment: Through this design, the installation of the wiring board 1 is simple and the fixation is more stable and reliable.

[0053] An intelligent vehicle cable laying method includes the following steps.

[0054] S1. Connect the vehicle battery electrode to one side of the terminal block 202;

[0055] S2. Connect the high-voltage line to the other side of the terminal block 202;

[0056] S3. Pass the high-voltage line through the high-voltage wire groove 101 and connect it to the voltage transformation module. The voltage transformation module is connected to the motor platform. Among them, the voltage transformation module has two lines, high voltage and low voltage. The high-voltage line is connected through the contact piece 204 and the connection block 206, usually 400 - 800V, and the low-voltage line is directly connected through the contact piece 204 in the terminal block 202, usually 100 - 400V;

[0057] S4. Install the low-voltage lines inside the vehicle in the wire harness board 3. The low-voltage lines are the lines for in-vehicle electronic components such as sensors, lighting, and in-vehicle infotainment systems, usually 12V.

[0058] S5. Lay the wiring board 1 on the surface of the vehicle battery and firmly fix the wiring board 1 and the vehicle frame with bolts; the limit slots 5 in the wiring board 1 match the battery compartment, the limit slots 5 are in contact with the vehicle battery, and the wall thickness at the position of the limit slots 5 on the wiring board 1 is relatively thin.

[0059] S6. When an emergency occurs in the vehicle, the protection module 2 disconnects the battery connection. The in-vehicle infotainment system sends a signal to the control module, and the control module activates the electromagnet 212 to open the jaws 211, so that the spring 210 pushes the pull rod 207 and the connecting block 206 to move, disconnecting the contact piece 204, thus providing protection; since there are various detection radars installed on the vehicle itself to determine whether the vehicle has collided and to activate 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.

[0060] S7. When the wiring board 1 is damaged, the pressure sensor transmits a signal to the control module, and the control module activates the electromagnet 212 to disconnect the contact piece 204. At the same time, the perfluoromethylcyclohexanone 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 vehicle collision causes the battery compartment to deform, 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, determines that a collision has occurred, and the control module transmits the signal to the electromagnet 212 to make the protection module 2 operate. This judgment method is a double criterion of interval and rate, that is, it not only identifies the pressure range but also the pressure change speed. In this way, the slight pressure change in the cavity 4 caused by temperature and normal vehicle driving bumps is excluded, and the control module synchronously receives the alarm signal and the pressure sensor signal sent from inside the vehicle, that is, any one of the signals during vehicle collision can make the control module activate the protection module 2 for power-off operation.

[0061] In this embodiment: Since the high-voltage line has a high voltage and poses a great threat to personnel, when the protection module 2 performs a power-off operation, it disconnects the high-voltage line module in the voltage conversion module, that is, the high-voltage line connected by the contact piece 204 and the connecting block 206 in S3. At this time, the low-voltage line remains connected. By this method, the working power of the motor is limited, the vehicle is in a low-power state, the battery output load and the vehicle working current are reduced in this way, the possibility of battery heating and fire is reduced in this way, and the safety of the vehicle is further improved. The low-voltage line can also enable other functions inside the vehicle to be used normally, avoiding the vehicle being completely powered off and paralyzed during a collision.

[0062] Furthermore:

[0063] 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.

[0064] 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.

[0065] 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.
