Description

  The present invention relates to a terminal cover device for a motive power line for a vehicle that runs on electric power.

  A fuel tank that stores fuel, for example hydrogen gas, a fuel cell stack (hereinafter simply referred to as a fuel cell) that generates electricity by a chemical reaction between fuel and air, more specifically oxygen in the air, a secondary battery, and a drive wheel Development of a fuel cell vehicle including a motor for driving the vehicle is underway.

  Here, many conventional fuel cell systems for four-wheeled vehicles generate a relatively large electric power of several tens of kW, and generate an equivalent amount of heat with power generation. Therefore, the conventional fuel cell system for four-wheeled vehicles includes a water-cooled cooling system with high cooling efficiency. Further, in order to generate a large amount of power, a compressor that sends a large amount of air to the fuel cell system is provided.

  A fuel cell motorcycle as an example of a conventional fuel cell vehicle includes a water-cooled fuel cell system capable of generating a relatively large amount of power. Such a fuel cell motorcycle has a radiator for cooling the fuel cell disposed near the front of the vehicle body, and a cooling unit disposed behind the radiator and thermally connecting the radiator, the fuel cell, and various electrical components. And a fuel cell disposed behind the cooling system and below the front end of the seat, and a fuel tank behind the fuel cell and substantially occupying the space below the seat (see, for example, Patent Document 1) .)

  On the other hand, although the air-cooled fuel cell system generates a relatively small amount of power of several kW, the radiator, cooling water pump, reservoir tank, and piping provided in the cooling system of the water-cooled fuel cell system are unnecessary. The heat generated by power generation can be cooled with air as a reaction gas. Further, the air-cooled fuel cell system has a low pressure loss in the air flow path. Thus, the air-cooled fuel cell system has a simple system configuration that requires a blower fan instead of a compressor as an auxiliary machine, and can also reduce the power consumption of the auxiliary machine. Therefore, there are examples in which an air-cooled fuel cell system is used in a fuel cell vehicle such as a fuel cell motorcycle capable of traveling at a lower output than a four-wheeled vehicle or a small electric vehicle such as a motor chair.

  The fuel cell vehicle includes a motor that drives driving wheels with electric power generated by the fuel cell, and a motor controller that controls operation of the motor.

  FIG. 10 is a perspective view showing a motor controller of a conventional fuel cell vehicle.

  As shown in FIG. 10, a conventional motor controller 100 for a fuel cell vehicle includes a terminal block 102 for a power line 101. The terminal block 102 includes a base portion 103 made of an insulating material, terminals 105 provided on the base portion 103 at a predetermined interval, a partition wall 106 standing on the base portion 103 and partitioning each terminal 105, A terminal block fixing portion 107 erected on the outer side of the terminal 105. The terminal 105 is, for example, a high voltage unit that receives a voltage exceeding 60 V in direct current.

  A cover member 108 is installed between the terminal block fixing portions 107 of the terminal block 102.

  The terminal block 102 of the motor controller of the conventional fuel cell vehicle configured as described above covers the terminal 105 with the cover member 108, and prevents conductive foreign matters such as dust from adhering to the terminal 105. Prevent short circuit.

  However, the cover member 108 does not surround the entire terminal block 102, but a wire that approaches the terminal 105 through the gap S1 between the partition walls 106 or the gap S2 between the partition wall 106 and the power line 101, etc. Can't block foreign objects. When a foreign substance such as a wire approaches and comes into contact with the terminal 105 from the gap S1 or the gap S2, a short circuit occurs between the terminals 105, which may cause damage to electrical components such as the motor controller 100, the fuel cell, and the secondary battery. . In addition, there is a risk of an electric shock accident due to a human body contacting between the terminals 105.

  On the other hand, if the terminal block 102 is simply covered or covered with an insulating material, the workability in the maintenance and inspection of the power line 101 and the terminal block 102 is significantly reduced.

  Therefore, the present invention proposes a terminal cover device for a motive power line for a vehicle that can easily perform maintenance and inspection of the power line and the terminal block, and can reliably protect the terminal from foreign objects and the approach of the human body.

In order to solve the above problems, a fuel cell vehicle according to the present invention includes a vehicle body, a seat disposed above the vehicle body, a secondary battery disposed below the seat, a lower portion of the seat, and the A power management device disposed behind the secondary battery, and a fuel cell disposed below the seat and behind the power management device , wherein the terminal block is electrically connected to a plurality of devices. A plurality of power lines to be connected are connected, and the terminal block protection cover body is divided to cover the power lines for each of the devices .

  According to the present invention, it is possible to provide a fuel cell vehicle that includes an air-cooled fuel cell, has high safety against fuel tank protection and fuel leakage, etc., and has good cooling performance for fuel cells and various electrical components.

Each lower frame 25 includes a footrest 29 for the rider on the front side thereof. The lower frame 25 positioned on the left side of the vehicle body 3 includes a side stand bracket 30. The side stand bracket 30 is swingably provided with a side stand 31 that allows the fuel cell motorcycle 1 to stand on its own in a left-tilt state.

  In addition, the frame 10 includes a guard frame 33 provided on a bent portion on the rear side of the lower frame 25. A center stand 34 for allowing the fuel cell motorcycle 1 to stand on its own is swingably provided on the guard frame 33.

  The vehicle body 3 includes the fuel tank 15 in the center tunnel region 35 surrounded by the pair of left and right upper frames 24 and the pair of left and right lower frames 25 by the frame 10 thus configured. 11 and the device mounting area 36 (device mounting space) surrounded by the seat 12 includes the fuel cell 2, the secondary battery 16, the power management device 17, and the motor controller 18. In the device mounting area 36, the secondary battery 16, the power management device 17, and the fuel cell 2 are arranged in this order from the front side of the vehicle body 3. The motor controller 18 is provided on the side of the power management device 17, for example, on the left side of the vehicle body 3. In addition, the rear wheel 7 is disposed in a tire house region 37 behind the center tunnel region 35 of the frame 10 and below the device mounting region 36. A partition wall member 39 is provided between the device mounting area 36 and the tire house area 37 to partition each area.

  The exterior 11 includes a front leg shield cover 41 that covers the front half of the vehicle main body 3, a front frame cover 42 that is positioned at the upper center of the vehicle main body 3 and covers the upper frame 24, and a rear half of the vehicle main body 3. And a frame cover 43 that covers the lower part of the seat 12 among the side surfaces of the vehicle body 3. The frame cover 43 divides the device mounting area 36 in which the fuel cell 2, the secondary battery 16, the power management device 17, and the motor controller 18 are accommodated together with the seat 12. Therefore, the device mounting area 36 is a sealed space surrounded by the seat 12, the frame cover 43, and the partition wall member 39, and vent holes (not shown) are provided at appropriate positions on the frame cover 43 or the partition wall member 39. By providing, the flow of air as the reaction gas supplied to the fuel cell 2 can be easily and reliably controlled, and the flow of air as the cooling air can be easily and reliably controlled for the electrical components that require cooling. . The device mounting area 36 does not have to be a complete airtight space.

  The seat 12 is positioned in the upper half of the rear half of the vehicle body 3. The seat 12 is a tandem type, and a front portion 12a on which a driver is seated and a rear portion 12b on which a passenger is seated are integrally formed.

  The fuel cell 2 is arranged so as to be biased to the rear side of the device mounting area 36 defined below the seat 12. More specifically, the fuel cell 2 is disposed below the rear portion 12b of the seat 12 on which the passenger sits. The fuel cell 2 is formed in a flat cubic shape, and the intake surface 2a having a reaction gas inlet is directed forward and upward of the vehicle body 3 and tilted forward. Specifically, the intake surface 2 a of the fuel cell 2 is directed to a stepped portion between the front portion 12 a and the rear portion 12 b of the seat 12. Thereby, the fuel cell 2 can secure a relatively large gap between the intake surface 2a and the seat 12, and can sufficiently suck the atmosphere (air) of the device mounting region 36, which is a reactive gas.

  The fuel cell 2 has a fan 45 and sucks the atmosphere (air) in the device mounting area 36 as a reaction gas from the intake surface 2a. The fuel cell 2 generates power by a chemical reaction between the hydrogen gas supplied from the fuel tank 15 and oxygen contained in the air, and then discharges the wet surplus gas from the exhaust port 46. In this process, the fuel cell 2 is cooled by air as a reaction gas. The exhaust port 46 of the fuel cell 2 communicates with the exhaust duct 47.

  The exhaust duct 47 is disposed behind the fuel cell 2 and guides the exhaust of the fuel cell 2 to an exhaust port 48 opened at the rear end of the vehicle body 3. The exhaust duct 47 communicates with the exhaust port 46 of the fuel cell 2 at the front lower end thereof, and at the rear end thereof above the communication position of the exhaust port 46 of the fuel cell 2, preferably at the rear upper end. An exhaust port 48 is provided.

  The fuel tank 15 stores hydrogen gas as fuel for the fuel cell 2. The fuel tank 15 is, for example, an about 35 MPa high-pressure compressed hydrogen storage system. The fuel tank 15 extends in the center tunnel region 35 substantially at the lower center of the vehicle body 3 such that its longitudinal axis is along the front-rear direction of the vehicle body 3. Therefore, the fuel tank 15 is surrounded by the pair of upper frames 24 and the pair of lower frames 25, and is securely protected against accidents such as a collision of the fuel cell motorcycle 1. The fuel tank 15 is sandwiched between footrests 29 provided on the lower frame 25.

  The fuel tank 15 is disposed on an upper frame 24 disposed on one side of the vehicle body 3, for example, an upper frame 24 disposed on the right side of the vehicle body 3, and on the other side of the vehicle body 3. The lower frame 25 is fixed to the center tunnel region 35 by a clamp band 49 laid between the lower frame 25, for example, the lower frame 25 disposed on the left side of the vehicle body 3. The clamp band 49 may be installed between the upper frame 24 disposed on the left side of the vehicle body 3 and the lower frame 25 disposed on the right side of the vehicle body 3.

Specifically, the fuel filling port 53 is disposed outside the device mounting area 36 in which a large number of devices are accommodated, in the vicinity of the upper down frame 22, and covered with the front frame cover 42. More specifically, the fuel filling port 53 is disposed near the upper part of the front end plate of the pressure vessel 51.

  The secondary battery 16 is a box-shaped lithium ion battery. The secondary battery 16 is disposed to be biased to the front side of the device mounting area 36 defined below the seat 12 and is disposed above the rear end plate of the pressure vessel 51 of the fuel tank 15. More specifically, the secondary battery 16 is disposed below the front portion 12 a of the seat 12 on which the rider sits, and is substantially upright on a virtual horizontal plane of the fuel cell motorcycle 1.

  In addition to the secondary battery 16, the fuel cell motorcycle 1 includes a secondary battery 56 capable of supplying 12V power as a power source for meters (not shown) and lamps (not shown). The secondary battery 56 is disposed on the side of the pressure vessel 51 of the fuel tank 15, for example, on the right side of the vehicle body 3. The secondary battery 56 is disposed below the fuel filling port 53 and at the front of the vehicle body 3 relative to the valve portion 52 of the fuel tank 15. Even if hydrogen gas, which is fuel, leaks from the fuel filling port 53, the hydrogen gas rises toward the upper side of the fuel cell motorcycle 1, and thus diffuses outside the vehicle without staying in the vehicle. Even if hydrogen gas, which is fuel, leaks from the valve portion 52, the hydrogen gas moves toward the tire house region 37, and therefore diffuses outside the vehicle without staying in the vehicle.

  The power management device 17 is disposed between the secondary battery 16 and the fuel cell 2. Further, the power management device 17 is tilted and held in the gap between the secondary battery 16 and the fuel cell 2. Similarly to the power management device 17, the motor controller 18 arranged in parallel with the power management device 17 is sandwiched between the secondary battery 16 and the fuel cell 2, and is tilted backward in the gap between the secondary battery 16 and the fuel cell 2. Being held.

The wiring length between the devices can be shortened and the weight related to the wiring can be reduced.

  The motor controller 18 is provided in parallel with the power management device 17. Specifically, the motor controller 18 is disposed on the left side of the vehicle body 3, and the power management device 17 is disposed on the right side of the vehicle body 3. The motor controller 18 has cooling fins 57 facing downward of the vehicle body 3.

  The vehicle controller 19 is disposed in front of the lower frame 25 and is opposed to the front end plate of the fuel tank 15.

  The front wheel 5 is rotatably supported on the front fork 27. The front fork 27 is configured to have an elastically telescopic structure, and supports the front fender 58 above the front wheel 5. The handle 6 is connected to the upper end portion of the front fork 27. The front wheel 5, the front fork 27, and the handle 6 are pivotally supported around the head pipe 21 to constitute a steering mechanism 59 of the fuel cell motorcycle 1.

  The rear wheel 7 is pivotally supported by a swing arm 60 pivotably attached to the pivot 28. The swing arm 60 is elastically supported by the frame 10 via the rear suspension 62.

  The motor 8 is a prime mover of the fuel cell motorcycle 1 that drives the rear wheel 7. The motor 8 is integrally attached to the swing arm 60 and constitutes a unit swing type swing arm. The motor 8 is connected to the rear wheel 7 via a transmission (not shown). The driving force generated by the motor 8 is transmitted to the rear wheel 7 via the transmission.

  The vehicle body 3 also includes fuel leak detectors 63 and 64 that detect leakage of hydrogen gas, which is fuel. The fuel leakage detectors 63 and 64 are configured using a hydrogen gas detector capable of detecting hydrogen gas. The fuel leak detector 63 is disposed on the upper side of the device mounting area 36, that is, the internal space of the seat 12. The fuel leak detector 64 is disposed in the center tunnel region 35 at a position close to the tire house region 37 in the vicinity of the space near the valve portion 52 of the fuel tank 15. The hydrogen gas is lighter than the air that is the atmosphere of the equipment mounting area 36 and the center tunnel area 35, and is easy when hydrogen gas leaks from the fuel cell 2, the fuel tank 15, or the intermediate pipe between the fuel tank 15 and the fuel cell 2. Can be detected. In particular, the device mounting area 36 is a sealed space, and when hydrogen gas as fuel leaks from the fuel cell 2 or a piping system (not shown) in the vicinity thereof, the fuel leakage detector 63 promptly fuels the fuel. Can be detected. Further, the fuel leak detector 64 ensures that even when the hydrogen gas as the fuel leaks from the vicinity of the valve portion 52 of the fuel tank 15, the leaked fuel easily flows out into the tire house region 37 due to traveling wind or the like. Fuel leakage can be detected.
