Description

Vehicle with a steering wheel

Technical Field

The present invention relates to a vehicle having an electronic device for communication and a cooling device that circulates an electrically conductive coolant in a coolant flow path by a pump with an electric motor and radiates heat by a radiator.

Background

In japanese patent laid-open publication No. 2013-072385 (hereinafter referred to as "JP 2013-one 072385A"), an object thereof is to provide a liquid supply apparatus ([0013], abstract) capable of simultaneously achieving weight reduction of the apparatus and suppression of electromagnetic noise transmitted from an electric motor to the surroundings. To achieve this object, an HV cooling system 1 of JP 2013-072385A (abstract) includes a pump 2 with an electric motor, which includes a pump 21 and an electric motor 22, and cooling water having conductivity is supplied to a predetermined supply target member by the pump 2 via a hose 3.

The HV cooling system 1 is provided with a housing 20 and metal pipe members 41 and 42 through which a conductive liquid passes. The housing 20 houses the pump 21 and the electric motor 22 and is formed of a non-conductive material. The metal pipe members 41 and 42 are provided at the middle or end of the hose 3 and grounded. Accordingly, it is intended to suppress electromagnetic noise transmitted to the surroundings regardless of the conductivity of the cooling water and the path length of the hose 3 forming the antenna for transmission.

The earthing of the tube parts 41, 42 is performed by connecting brackets 51, 52 and mounting bracket 50 ([0042], fig. 5). Further, as modification 1A, a configuration in which a hose 3A made of a conductive rubber material is grounded via a mounting bracket 50A is shown ([0047], [0048], fig. 7). Further, as modification 1B, a configuration in which a hose 3B made of a conductive rubber material is grounded via a metal jig 62A is shown ([0049], [0050], fig. 8).

Disclosure of Invention

As described above, in JP 2013-containing 072385A, grounding of the pipe members 41, 42 or the hoses 3A, 3B ([0042], [0047] - [0050], fig. 5, fig. 7, fig. 8) is performed using

various brackets

50, 51, 52, 50A or clamps 62A. However, when only the

brackets

50, 51, 52, and 50A or only the jig 62A is used, there are design restrictions on the installation place and the like.

The present invention has been made in view of the above-described problems, and an object thereof is to provide a vehicle capable of improving the degree of freedom in design associated with grounding using a conductive coolant, and the like.

The vehicle according to the present invention includes an electronic device for communication and a cooling device that circulates a conductive coolant in a coolant flow path by a pump having an electric motor and radiates heat by a radiator,

it is characterized in that the preparation method is characterized in that,

the vehicle further has a resin bulkhead supporting the radiator at a front of a vehicle body,

the cooling device has a metal tube and a wire, wherein,

the metal pipe is supported by the resin separator and constitutes a part of the coolant flow path,

the conducting wire is electrically connected with the metal tube and is grounded on the vehicle body.

According to the present invention, the grounding of the metal pipe is performed by a wire (metal wire or the like). Therefore, the degree of freedom in design of the structure for grounding accompanying the use of the conductive coolant is improved. In addition, compared with the bracket and the clamp in JP 2013-072385A, the light weight is easy to realize.

In the present invention, the radiator and the metal pipe are supported by the resin spacer. This makes it easier to reduce the weight of the separator as compared with the case of using a metal separator.

In addition, when the metal pipe is supported by the partition plate made of resin (particularly, when both ends of the metal pipe are supported by the partition plate), the distance from the metal pipe to the ground may be increased. In this case, too, the metal pipe can be easily grounded by using a wire.

Further, the metal pipe is superior in cost and ease of assembly as compared with a non-conductive resin pipe, but is inferior in necessity of grounding, and even in this case, the advantage of the metal pipe can be effectively utilized by facilitating grounding of the metal pipe using a lead wire.

The electronic device for communication may be disposed behind the heat sink and the resin spacer. The metal pipe may be disposed forward of the radiator and the resin spacer. Accordingly, a radiator and a resin spacer are interposed between the electronic device for communication and the metal pipe. Therefore, electromagnetic noise from the metal pipe is mitigated by the radiator and the partition plate. In addition, the distance between the electronic device for communication and the metal pipe is relatively long, so that electromagnetic noise hardly reaches the electronic device for communication. Therefore, the electronic equipment for communication is easily protected from electromagnetic noise emitted from the metal pipe.

Further, since the metal pipe is generally excellent in heat radiation performance, in the present invention, the metal pipe is disposed forward of the radiator and the resin partition plate. Therefore, when the vehicle travels, the metal pipe is easily subjected to wind generated by the travel, and the cooling performance of the cooling device can be improved.

Further, when the drive source (engine or the like) is disposed behind the resin bulkhead, the metal pipe is disposed at a position forward of the resin bulkhead, and thus a space (engine compartment or the like) for accommodating the drive source is easily secured.

A connection position for electrically connecting the lead wire to the metal pipe may also be provided near the coolant inflow port of the metal pipe. Electromagnetic noise generated by a pump or the like having an electric motor propagates in the coolant flow path in accordance with the flow of the conductive coolant. The propagated electromagnetic noise is liable to propagate through the metal pipe to the outside. Therefore, by providing the connection position of the lead wire in the vicinity of the coolant inflow port of the metal pipe, a high noise reduction effect can be obtained.

The resin bulkhead may be supported by a front end of the front side frame. Further, the resin spacer may be provided with a hole penetrating in the front-rear direction of the vehicle. The lead may also be grounded to the front side frame by (via) the hole. Accordingly, the lead wires can be shortened as compared with a case where the lead wires are grounded to the front side frame while avoiding the resin partition plate.

The lead wire connected to the metal tube may be grounded together with other lead wires connected to other components (e.g., a headlight) via a fixing member. Accordingly, the grounding point can be shared, and the number of fixing members (bolts, nuts, and the like) can be reduced. In addition, when the fixing member uses a bolt, a nut, or the like, the number of holes formed in the vehicle body can be reduced, and the rigidity or impact performance of the vehicle body can be improved.

The cooling device may include a metal bracket welded to the metal pipe. The lead may also be connected to the metal tube by the bracket. Accordingly, the lead wire is easily arranged as compared with the case where the lead wire is directly connected to the metal pipe. In addition, when the lead wire is fixed to the metal pipe side by a fixing member such as a bolt or a nut, the lead wire is fixed to the bracket without being fixed to the metal pipe itself, and therefore, the manufacturing is easy and the durability of the metal pipe can be improved.

The bracket may be supported by the resin spacer in addition to the fixing portion with the metal pipe. Accordingly, the bracket is supported at two places of the metal pipe and the resin spacer. Therefore, the vibration resistance of the bracket can be improved.

The bracket can also be provided with a convex rib. By providing the rib (raised portion), the rigidity of the stent can be increased. Alternatively, the weight and cost of the stent can be reduced by making the stent thinner in accordance with the increase in rigidity by the ribs and satisfying the rigidity required for the stent.

The wires may also be covered by a resin cover. Accordingly, even when the lead wire swings and interferes with other members as the vehicle travels, breakage of the lead wire can be prevented.

The above objects, features and advantages should be readily understood from the following description of the embodiments with reference to the accompanying drawings.

A. One embodiment of the invention

< A-1. Structure >

[ A-1-1. Overall Structure ]

Fig. 1 is a schematic overall configuration diagram of a vehicle 10 according to an embodiment of the present invention. The vehicle 10 is a so-called hybrid vehicle, and has an engine 20 and a travel motor 22. As will be described later, the vehicle 10 may be another type of vehicle.

In addition to the engine 20 and the travel motor 22, the vehicle 10 also has a Power Control device 24 (hereinafter referred to as "PCU 24". PCU: Power Control Unit), a partition plate (bulk head)26, a cooling device 28, and a communication electronic device 30.

[ A-1-2. Engine 20 and traveling Motor 22]

The engine 20 generates a driving force in accordance with a command from an engine electronic control device, not shown. The travel motor 22 generates a driving force from electric power supplied from a high-voltage battery (not shown) by the PCU24, and rotates wheels (not shown) by the driving force via a transmission (not shown). The motor 22 outputs electric power (regenerative electric power) generated by regeneration to the high-voltage battery or the like. The engine 20 and the travel motor 22 are suspended from the front side frame 42.

[A-1-3.PCU24]

The PCU24 controls the supply of electric power to the travel motor 22, and controls regenerative electric power of the motor 22. The PCU24 includes a DC/DC converter for voltage step-up and step-down (not shown), an inverter (inverter) for the travel motor 22, and a motor electronic control device. The PCU24 is disposed above the travel motor 22. In addition, the PCU24 is cooled by the cooling device 28.

[ A-1-4. separator 26]

Fig. 2 is a perspective view showing the entire separator 26 and a part of the cooling device 28 according to the present embodiment. Fig. 3 is an enlarged perspective view showing a part of the separator 26 and a part of the cooling device 28 in the present embodiment. The bulkhead 26 defines a housing space (e.g., an engine compartment) for the engine 20 and the travel motor 22. The separator 26 of the present embodiment is made of resin (particularly, a nonconductive or insulating separator). Hereinafter, the separator 26 is also referred to as a "resin separator 26".

As shown in fig. 1 and 2, the bulkhead 26 supports a radiator 50 of the cooling device 28 in front of the vehicle body 40. As shown in fig. 1 and 3, the bulkhead 26 is supported by a front side frame 42 (particularly, the front end thereof) that constitutes a part of the vehicle body 40.

As shown in fig. 3, a hole 44 penetrating in the front-rear direction of the vehicle 10 is formed in the bulkhead 26. A wire 60 forming part of the cooling device 28 is inserted in the hole 44.

[ A-1-5. Cooling device 28]

(A-1-5-1. outline of Cooling device 28)

Fig. 4 is a perspective view showing an outline of cooling device 28 according to the present embodiment. In the cooling device 28, the conductive coolant is circulated in the coolant flow path 52 by a pump 54 with an electric motor (hereinafter also referred to as "pump 54") and heat is radiated by the radiator 50. This cools the PCU24 disposed in the coolant flow path 52. The arrows in fig. 4 indicate the flow of the conductive coolant. In addition to the radiator 50, the coolant flow path 52, and the pump 54, the cooling device 28 has a water storage tank (reservoir tank)56,

brackets

58a, 58b, and a lead 60 (fig. 3).

(A-1-5-2. radiator 50)

As shown in fig. 1 and 2, the radiator 50 is supported by the bulkhead 26 in front of the vehicle body 40.

(A-1-5-3. coolant flow path 52)

The coolant flow path 52 circulates a conductive coolant, and includes a resin pipe 70 and a metal pipe 72. The "conductivity" of the conductive coolant means the nature of electromagnetic noise generated within the vehicle 10 (e.g., pump 54) by self-propagation.

The metal pipe 72 (conductive pipe) is supported by the resin separator 26 and constitutes a part of the coolant flow path 52. As shown in fig. 1 and 2, the metal pipe 72 is disposed forward of the radiator 50 and the resin separator 26. Therefore, in the coolant flow path 52, only the portion near the radiator 50 is made of metal, and the other portions are made of resin. However, the other portions may also include metal portions.

(A-1-5-4. Pump with electric Motor 54)

A pump 54 with an electric motor circulates the conductive coolant in the coolant flow path 52. When electromagnetic noise is generated in accordance with the operation of the pump 54, the electromagnetic noise propagates through the conductive coolant. If this noise is propagated to the electronic communication device 30 through the metal pipe 72 or the like, the electronic communication device 30 may be adversely affected. As will be described later, in the present embodiment, the metal pipe 72 is grounded via the lead wire 60, thereby suppressing the metal pipe 72 from transmitting noise.

The

brackets

58a and 58b are metal members welded to the metal pipe 72. The

brackets

58a, 58b are supported by the resin bulkhead 26 in addition to the fixing portions (e.g., welding portions) with (between) the metal pipes 72. That is, as shown in fig. 3 and the like, the end of the bracket 58a is fixed to the resin bulkhead 26 by a bolt 80. The same applies to the bracket 58 b.

As shown in fig. 3, the holder 58a is provided with a rib 82 (a portion protruding from the peripheral portion). In particular, the rib 82 of the present embodiment protrudes toward the front of the vehicle 10 with respect to the peripheral planar portion. The same applies to the bracket 58 b.

(A-1-5-6. lead 60)

Fig. 5 is a diagram showing a grounding position of the lead 60 according to the present embodiment. The lead 60 is a member electrically connected to the metal pipe 72 and grounded to the vehicle body 40 (particularly, the front side frame 42). As shown in fig. 3 and 5, the lead 60 is covered with a resin cover 90.

As shown in fig. 3, a connection position for electrically connecting the lead wire 60 with the metal pipe 72 is provided in the vicinity of the coolant inflow port of the metal pipe 72. In the present embodiment, the lead 60 is connected to the metal pipe 72 via the bracket 58 a. More specifically, the lead 60 is mounted to the bracket 58a by fixing the tube-side terminal 92 mounted to the tip end of the lead 60 with a bolt 94.

As shown in fig. 3 and 5, the lead 60 is grounded to the front side frame 42. Specifically, the lead 60 connected to the metal pipe 72 is grounded by a bolt 106 (a fixing member) through a ground side terminal 104 together with another lead 102 connected to another component such as the headlamp 100 (fig. 1).

As shown in fig. 3, the lead wire 60 passes through the hole 44 of the bulkhead 26 between the metal pipe 72 and the ground point of the front side frame 42.

[ A-1-6. electronic device for communication 30]

The electronic communication device 30 according to the present embodiment is a radio receiver. The communication electronic device 30 may be another electronic device (e.g., a television receiver or a navigation device). As shown in fig. 1, the electronic device for communication 30 is disposed behind the heat sink 50 and the resin spacer 26. Specifically, the electronic device for communication 30 is disposed between the radiator 50, the resin partition 26, and the vehicle interior 110.

< A-2 > Effect of the present embodiment

As described above, according to the present embodiment, the metal pipe 72 is grounded via the lead 60 (fig. 3 and 5). Therefore, the degree of freedom in design of the structure for grounding accompanying the use of the conductive coolant is improved. In addition, compared with the bracket and the clamp in JP 2013-072385A, the light weight is easy to realize.

In the present embodiment, the radiator 50 and the metal pipe 72 are supported by the resin spacer 26 (fig. 2 and 3). This makes it easier to reduce the weight of the separator as compared with the case of using a metal separator.

Further, when the metal pipe 72 is supported by the partition plate 26 by using the resin as the partition plate 26 (particularly, when the partition plate 26 supports both ends of the metal pipe 72), the distance from the metal pipe 72 to the ground may be increased. Even in this case, the metal pipe 72 can be easily grounded by using the lead wire 60.

Further, the metal pipe 72 is superior in cost and ease of assembly as compared with the non-conductive resin pipe 70, but is inferior in necessity of grounding, and even in this case, the grounding of the metal pipe 72 can be facilitated by using the lead wire 60, and the advantage of the metal pipe 72 can be effectively utilized.

In the present embodiment, the electronic device for communication 30 is disposed behind the heat sink 50 and the resin spacer 26 (fig. 1). The metal pipe 72 is disposed forward of the radiator 50 and the resin separator 26 (fig. 1 and 2).

Accordingly, the heat sink 50 and the resin separator 26 are interposed between the electronic device for communication 30 and the metal pipe 72. Therefore, the electromagnetic noise from the metal pipe 72 is mitigated by the radiator 50 and the partition plate 26. In addition, the distance between the electronic device for communication 30 and the metal pipe 72 is relatively long, so that electromagnetic noise hardly reaches the electronic device for communication 30. Therefore, the electronic equipment for communication 30 is easily protected from electromagnetic noise emitted from the metal pipe 72.

In addition, since the metal pipe 72 generally has excellent heat radiation performance, in the present embodiment, the metal pipe 72 is disposed at a position forward of the radiator 50 and the resin separator 26 (fig. 1 and 2). Therefore, when the vehicle 10 travels, the metal pipe 72 is likely to receive wind generated by the travel, and the cooling performance of the cooling device 28 can be improved.

Further, the engine 20 and the traveling motor 22 (driving source) are disposed behind the resin bulkhead 26 (fig. 1), and the metal pipe 72 is disposed at a position forward of the resin bulkhead 26, whereby a space (engine compartment and the like) for accommodating the engine 20 and the motor 22 can be easily secured.

In the present embodiment, the connection position at which the lead wire 60 is electrically connected to the metal pipe 72 is provided in the vicinity of the coolant inlet of the metal pipe 72 (fig. 2 to 4). Electromagnetic noise generated by the pump 54 with an electric motor or the like propagates in the coolant flow path 52 in accordance with the flow of the conductive coolant. The propagated electromagnetic noise is liable to propagate through the metal pipe 72 to the outside. Therefore, by providing the connection position of the lead wire 60 in the vicinity of the coolant inflow port of the metal pipe 72, a high noise reduction effect can be obtained.

In the present embodiment, the resin bulkhead 26 is supported by the front end of the front side frame 42 (fig. 1 and 3). Further, a hole 44 (fig. 2 and 3) that penetrates in the front-rear direction of the vehicle 10 is formed in the resin partition plate 26. The lead 60 is grounded to the front side frame 42 (fig. 3 and 5) through the hole 44. Accordingly, the lead 60 can be shortened as compared with a case where the lead 60 is grounded to the front side frame 42 while avoiding the resin partition 26.

In the present embodiment, the lead 60 connected to the metal tube 72 is grounded together with another lead 102 connected to another component (e.g., the headlamp 100) by a bolt 106 (a fixing member) (fig. 3 and 5). Accordingly, the grounding point can be shared, and the number of fixing members (the bolt 106, the nut, and the like) can be reduced. In addition, when the bolts 106, nuts, or the like are used as the fixing members, the number of holes (bolt holes or the like) formed in the vehicle body 40 can be reduced, and thus the rigidity or impact performance of the vehicle body 40 can be improved.

In the present embodiment, the cooling device 28 includes a metal bracket 58a (fig. 2 to 4) fixed to the metal pipe 72. The lead 60 is connected to the metal tube 72 by the bracket 58a (fig. 3). Accordingly, the lead 60 is easier to arrange than in the case where the lead 60 is directly connected to the metal pipe 72. In addition, when the lead 60 is fixed to the metal pipe 72 side by a fixing member such as a bolt 106 or a nut, the lead 60 is fixed to the bracket 58a without fixing the lead 60 to the metal pipe 72 itself, and therefore, the manufacturing is easy and the durability of the metal pipe 72 can be improved.

In the present embodiment, the bracket 58a is supported by the resin spacer 26 in addition to the fixed portion to the metal pipe 72 (fig. 3). Accordingly, the bracket 58a is supported at both the metal pipe 72 and the resin partition 26. Therefore, the vibration resistance of the bracket 58a can be improved.

In the present embodiment, the holder 58a is provided with a rib 82 (fig. 3). By providing the rib 82 (raised portion), the rigidity of the holder 58a can be increased. Alternatively, the weight and cost of the holder 58a can be reduced by making the holder 58a thin in accordance with the increase in rigidity caused by the ribs 82 and satisfying the rigidity required for the holder 58 a.

In the present embodiment, the lead 60 is covered with a resin cover 90 (fig. 3 and 5). Accordingly, even when the lead 60 swings and interferes with other members as the vehicle 10 travels, breakage of the lead 60 can be prevented.

In the above embodiment, the metal pipe 72 is disposed near the radiator 50 (fig. 2 and 4). However, for example, the metal pipe 72 is not limited to this from the viewpoint of grounding using the lead wire 60. For example, the metal pipe 72 may be disposed away from the radiator 50.

In the above embodiment, a single metal pipe 72 (fig. 4) is used in the coolant flow path 52. However, for example, the metal pipe 72 is not limited to this from the viewpoint of grounding using the lead wire 60. For example, the coolant flow path 52 may include a plurality of metal pipes 72. In this case, it is preferable that each metal tube 72 is grounded via the lead wire 60 or the like.

In the above embodiment, the metal pipe 72 is used as a pipe having conductivity. However, for example, from the viewpoint of grounding the conductive tube by the lead 60, the present invention is not limited thereto, and a conductive resin tube may be used instead of the metal tube 72.

In the case of directly connecting the metal pipe 72 and the lead 60, the bracket 58a (and 58b) can be omitted.

In the above embodiment, the

In the above embodiment, the lead 60 is connected to the metal pipe 72 by the bracket 58a (fig. 3). However, for example, the present invention is not limited to this, from the viewpoint of electrically connecting the lead 60 and the metal pipe 72. For example, the lead 60 can be directly connected to the metal pipe 72 without providing the bracket 58 a.

In the above embodiment, the lead wire 60 is grounded to the front side frame 42 (fig. 3 to 5) which is a part of the vehicle body frame. However, for example, the present invention is not limited to this, from the viewpoint of grounding the lead 60. The lead 60 may be grounded to the vehicle body 40 (e.g., the engine 20 or the floor panel) other than the vehicle body frame.

In the above embodiment, the lead 60 connected to the metal tube 72 is grounded together with the other lead 102 connected to other components (the headlight 100 and the like) by the bolt 106 (the fixing member) (fig. 3 and 5). However, for example, from the viewpoint of grounding the lead 60 connected to the metal pipe 72, the present invention is not limited thereto, and the lead 60 may be grounded alone.

In the above embodiment, the lead 60 is covered with the resin cover 90 (fig. 3 and 5). However, for example, the resin cover 90 may be omitted from the viewpoint of grounding the metal pipe 72 using the lead wire 60.

< B-4. electronic device for communication 30 >

In the above embodiment, the electronic device for communication 30 is disposed between the radiator 50 and the resin partition 26 and the vehicle interior 110 (fig. 1). However, for example, the electronic device for communication 30 is not limited to this from the viewpoint of disposing it behind the heat sink 50 and the resin partition 26. For example, the electronic communication device 30 may be disposed behind the vehicle interior 110. Alternatively, the electronic device for communication 30 may be disposed on the side or front of the radiator 50 and the resin spacer 26 from the viewpoint of grounding the metal pipe 72 using the lead 60.
