Description

Front body structure of vehicle and vehicle

[0001] The present invention relates to a front body structure of a vehicle and a vehicle.

[0002] The vehicle described in Patent Document 1 includes a radiator provided at the front side of the vehicle, an electric radiator fan provided behind the radiator, and an electric water pump.

[0003] Japanese Patent Application Laid-Open No. 2020-142941

[0004] In the system disclosed in Patent Document 1, if the electric water pump is installed behind the electric radiator fan, when an obstacle comes into contact with the front of the vehicle, the electric radiator fan will interfere with the electric water pump, which could damage the harness connector of the electric water pump.

[0005] The present invention has been made in light of the above-mentioned circumstances, and aims to provide a front body structure for a vehicle and a vehicle that can suppress damage to the harness connector of an electric water pump when the vehicle comes into contact with an obstacle.

[0006] In order to achieve the above-mentioned object, the present invention provides a front body structure including a radiator, an electric radiator fan motor, a first electric water pump, and a second electric water pump. The radiator is provided at the front of the vehicle and supported by a vehicle frame component. The electric radiator fan motor is provided rearward of the radiator and rotates the radiator fan. The first electric water pump and the second electric water pump are provided rearward of the electric radiator fan motor and draw coolant to be supplied to the radiator. The first electric water pump is formed in a cylindrical shape and has a first harness connector provided at an end of the cylindrical shape closer to the second electric water pump in the cylindrical axis direction and in a portion other than the front side. The second electric water pump is formed in a cylindrical shape and has a second harness connector provided at an end of the cylindrical shape closer to the first electric water pump in the cylindrical axis direction and in a portion other than the front side.

[0007] In the vehicle front body structure according to the present invention, the first harness connector is formed at an end closer to the second electric water pump in the cylinder axis direction and at a location other than the front side. The second harness connector is formed at an end closer to the first electric water pump in the cylinder axis direction and at a location other than the front side. This makes it less likely that the electric radiator fan motor will interfere with the first and second harness connectors even if a load is applied to the radiator and electric radiator fan motor from an obstacle in front of the vehicle if the vehicle comes into contact with an obstacle in front of the vehicle. As a result, damage to the first and second harness connectors can be reduced even if the vehicle comes into contact with an obstacle in front of the vehicle.

[0009] A front body structure 1 of a vehicle 100 according to an embodiment and a vehicle 100 including the same will be described below with reference to the drawings. For ease of understanding, mutually orthogonal XYZ coordinates are set and referenced as appropriate. As shown in FIG. 1 , the X-axis direction of the XYZ coordinates is the longitudinal direction D1 of the vehicle 100, the Y-axis direction is the width direction D2 of the vehicle 100, and the Z-axis direction is the height direction of the vehicle 100. In addition, the same reference numerals in each drawing indicate the same or corresponding parts.

[0010] 1, the vehicle 100 includes a drive motor 50, a vehicle body 110, tires 120, side members 130, a front body structure 1, and other automobile components. The vehicle 100 is, for example, an electric vehicle (EV) equipped with the drive motor 50 for driving the tires 120. However, the vehicle 100 is not limited to this. The vehicle 100 may be an engine other than an electric vehicle equipped with the drive motor 50.

[0011] The front body structure 1 is located closer to the front (-X side) of the vehicle 100 than the windshield. As shown in FIG. 2 , the front body structure 1 includes a radiator 10, an electric radiator fan motor 20, a radiator fan, a first electric water pump 30, a second electric water pump 40, a drive motor 50 (drive source), a steering rack 60, and an electric power steering device 70 having various electrical components. If the vehicle 100 is an electric vehicle, there are multiple electronic devices that need to be cooled, and the cooling temperatures may vary. Therefore, if the front body structure 1 only has one electric water pump, the pump suction force may be insufficient. For this reason, in this embodiment, the front body structure 1 includes two electric water pumps: first and second electric water pumps 30 and 40. However, this is not limited to this. The front body structure 1 may include three or more electric water pumps depending on the number and types of electronic devices to be cooled.

[0012] The radiator 10 cools electronic devices such as a motor and an inverter provided in the vehicle 100, which is an electric vehicle. A coolant circuit C through which cooling water flows is connected to the radiator 10. Wind W generated by the vehicle 100 running passes through the radiator 10, cooling the water. The coolant circuit C through which water flows is connected to electronic devices (not shown), and the water in the coolant circuit C reaches the electronic devices and absorbs heat generated by the electronic devices to cool them. The water that has absorbed the heat from the electronic devices then circulates again and reaches the radiator 10. The water that reaches the radiator 10 is cooled by the radiator 10 and dissipates heat.

[0013] The electric radiator fan motor 20 is a motor that rotates a radiator fan (not shown). The electric radiator fan motor 20 has a motor body and a motor housing that houses the motor body. The electric radiator fan motor 20, together with the radiator fan, is attached to the rear of the radiator 10 by a radiator fan shroud 11. By rotating the radiator fan, the electric radiator fan motor 20 increases the amount of air passing through the radiator 10, improving the cooling efficiency of the water flowing through the coolant circuit C. Both a first electric water pump 30 and a second electric water pump 40 are provided behind the electric radiator fan motor 20. The electric radiator fan motor 20 has a harness connector 21.

[0014] The harness connector 21 is a connector for connecting a harness that supplies power to the motor body of the electric radiator fan motor 20 .

[0015] As shown in FIG. 3 , the first electric water pump 30 is housed in the front body of the vehicle 100 together with the second electric water pump 40. The first electric water pump 30 has a pump body and a housing that covers the pump body. The first electric water pump 30 is connected to the coolant circuit C (see FIG. 2 ) to circulate the coolant within the coolant circuit C (see FIG. 2 ). The first electric water pump 30 circulates the coolant. The first electric water pump 30 can also adjust the flow rate of the coolant flowing through the coolant circuit C (see FIG. 2 ) by controlling its rotation speed. As shown in FIGS. 4 and 5 , the first electric water pump 30 is formed in a substantially cylindrical shape with an end surface 30a on the −Y side. In this embodiment, the end surface 30a of the first electric water pump 30 is formed as a flat surface. The first electric water pump 30 has a first harness connector 31.

[0016] The first harness connector 31 is a connector for connecting a harness 32 that supplies electric power to the pump body of the first electric water pump 30. The first harness connector 31 is provided near one end (-Y side) of the first electric water pump 30 in the axial direction (Y axis direction) of the substantially cylindrical shape of the first electric water pump 30. Specifically, the first harness connector 31 is provided on the upper outer circumferential surface of the first electric water pump 30 near an end face 30a on the -Y side, and in a portion other than the front side (-X side). The harness 32 connected to the first harness connector 31 is pulled downward (-Z direction), bent at a bend 32a, and extended upward.

[0017] The second electric water pump 40 has a pump body and a housing that covers it. Like the first electric water pump 30, the second electric water pump 40 is connected to circulate cooling water within the circuit. The second electric water pump 40 can adjust the flow rate of cooling water flowing within the circuit by controlling its rotation speed. The second electric water pump 40 is formed in a generally cylindrical shape with an end face 40a on the +Y side. In this embodiment, the end face 40a of the second electric water pump 40 is formed as a flat surface. The generally cylindrical end face 40a of the second electric water pump 40 is positioned so that it faces the generally cylindrical end face 30a of the first electric water pump 30. The second electric water pump 40 has a second harness connector 41.

[0018] The second harness connector 41 is a connector for connecting a harness 42 that supplies electric power to the pump body of the second electric water pump 40. The second harness connector 41 is provided near one end (+Y side) of the second electric water pump 40 in the axial direction (Y axis direction) of the substantially cylindrical shape of the second electric water pump 40. Specifically, the second harness connector 41 is provided on an upper portion of the outer circumferential surface near an end face 40a on the +Y side of the second electric water pump 40, in a portion other than the front side (-X side). The second harness connector 41 is disposed at a different height in the vehicle height direction D3 than the first harness connector 31, as viewed from the front of the vehicle 100. Specifically, in the present embodiment, the second harness connector 41 is disposed at a higher position than the first harness connector 31, as viewed from the front of the vehicle 100. The harness 42 connected to the second harness connector 41 is pulled upward (+Z direction) and is bundled with the harness 32 by, for example, a bundling member U.

[0019] The first electric water pump 30 and the second electric water pump 40 are arranged such that the first harness connector 31 and the second harness connector 41 face each other in the vehicle width direction D2. Specifically, the first harness connector 31 has an opening 33 that opens in an opening direction Y1 (-Y direction). The second harness connector 41 has an opening 43 that opens in an opening direction Y2 (+Y direction), which is the direction opposite to the opening direction Y1. In this embodiment, the opening direction Y1 of the first harness connector 31 is offset in the vehicle height direction D3 from the opening direction Y2 of the second harness connector 41. Furthermore, the harnesses 32 and 42 are drawn out from the openings 33 and 43.

[0020] 6, the first electric water pump 30 and the second electric water pump 40 are disposed at approximately the same position in the fore-and-aft direction D1 of the vehicle 100. Specifically, the second electric water pump 40 is disposed slightly rearward of the position of the first electric water pump 30 in the fore-and-aft direction D1. The second electric water pump 40 is disposed, for example, about 1 to 3 centimeters rearward of the position of the first electric water pump 30 in the fore-and-aft direction D1. However, the present invention is not limited to this, and the second electric water pump 40 may be disposed at the same position as the first electric water pump 30 in the fore-and-aft direction D1, although it may be slightly shifted rearward in design.

[0021] A gap S is formed between the first electric water pump 30 and the second electric water pump 40. More specifically, the gap S is formed between the end face 30a of the first electric water pump 30 and the end face 40a of the second electric water pump 40. The electric radiator fan motor 20 is disposed in front of the gap S. As shown in Figures 6 and 7 , the width L1 of the electric radiator fan motor 20 in the vehicle width direction D2 is larger than the width L2 of the gap S.

[0022] As shown in Figure 1, the drive motor 50 is built into the vehicle body 110 and is a drive source that drives the vehicle 100 in the fore-and-aft direction D1. The drive motor 50 has a motor body and a housing that covers the motor body. As shown in Figure 2, the drive motor 50 is provided behind both the first electric water pump 30 and the second electric water pump 40.

[0023] The steering force input by the driver to a steering wheel (not shown) is transmitted to the steering rack 60 via a steering shaft. The steering wheel is connected to the steering rack 60 via the steering shaft. The steering rack 60 is also connected to the wheels via parts such as tie rods. The steering rack 60 is disposed below (in the -Z direction) the first electric water pump 30 and the second electric water pump 40. As shown in FIG. 3 , a portion of the steering rack 60 is disposed so as to overlap the radiator fan shroud 11 in the X-axis direction.

[0024] The electric power steering device 70 is a mechanism that assists the driver in steering and has a plurality of electrical components. As shown in Figures 2 and 3, the electric power steering device 70 is supported on the rack housing of the steering rack 60 in front of the first electric water pump 30 and the second electric water pump 40. Specifically, the electric power steering device 70 has, as electrical components, an electric power steering controller 71, an electric power steering motor 72, a gearbox 73, and a reducer.

[0025] The electric power steering controller 71 is disposed, for example, between the electric radiator fan motor 20 and the drive motor 50. This electric power steering controller 71 is, for example, an MCU (Micro Controller Unit) that controls the rotation speed of the electric power steering motor 72. When the steering wheel is operated, the electric power steering controller 71 reads information such as the steering torque, steering angle, and vehicle speed, calculates a target value for assist based on this information, and outputs this to the electric power steering motor 72.

[0026] Similar to the electric power steering controller 71, the electric power steering motor 72 is disposed between the electric radiator fan motor 20 and the drive motor 50. The electric power steering motor 72 has an output shaft that meshes with one of the gears of the reduction gear. The electric power steering motor 72 transmits driving force to the gear of the reduction gear by rotation of the output shaft.

[0027] The gearbox 73 is attached to the steering rack 60. The gearbox 73 houses a reducer that reduces the rotation of the rotary shaft of the electric power steering motor 72. The reducer transmits the driving force of the electric power steering motor 72 to the rack shaft of the steering rack 60, and adds the driving force of the electric power steering motor 72 to the steering force transmitted to the rack shaft of the steering rack 60 by operation of the steering wheel.

[0028] As described above, in this embodiment, as shown in FIGS. 4 and 5 , the first harness connector 31 is formed on the end of the first electric water pump 30, which is formed in a substantially cylindrical shape, on the axial end face 30a side (closer to the second electric water pump 40), and in a portion other than the front side. The second harness connector 41 is formed on the end of the second electric water pump 40 on the axial end face 40a side (closer to the first electric water pump 30), and in a portion other than the front side. Therefore, as shown in FIG. 8A , when the vehicle 100 comes into contact with an obstacle ahead, an impact is applied from the obstacle to the radiator 10 and the electric radiator fan motor 20. Then, as shown in FIG. 8B , the impact tends to cause the electric radiator fan motor 20 to interfere with the housings of the first and second electric water pumps 30, 40 before the first and second harness connectors 31, 41 do. This makes it less likely that the electric radiator fan motor 20 will interfere with the first and second harness connectors 31, 41.

[0029] In particular, in this embodiment, the first harness connector 31 is provided on the upper outer peripheral surface of the first electric water pump 30 near the -Y-side end face 30a, but in a location other than the front side (-X side). The second harness connector 41 is provided on the upper outer peripheral surface of the second electric water pump 40 near the +Y-side end face 40a, but in a location other than the front side (-X side). This makes it easier for the electric radiator fan motor 20 to interfere with the housings of the first and second electric water pumps 30, 40 before the first and second harness connectors 31, 41 interfere. This also makes it possible to prevent damage to the first and second harness connectors 31, 41 even if the vehicle 100 comes into contact with an obstacle ahead. As a result, electrical failures, such as electric leakage, caused by damage to the first and second harness connectors 31, 41 can be prevented.

[0030] Additionally, in this embodiment, the first and second harness connectors 31, 41 are provided on the mutually facing end surfaces 30a, 40a of the first and second electric water pumps 30, 40. Therefore, as shown in FIG. 9 , when an obstacle collides with the vehicle 100 from the oblique front, the side member 130 is bent inward and deformed. A portion of the side member 130 is likely to interfere with the housings of the first and second electric water pumps 30, 40 before the first and second harness connectors 31, 41 do. As a result, even when an obstacle collides with the vehicle 100 from the oblique front, damage to the first and second harness connectors 31, 41 can be suppressed. As a result, electrical failures such as electric leakage caused by damage to the first and second harness connectors 31, 41 can be prevented.

[0031] 6 and 7 , in this embodiment, the width L1 of the electric radiator fan motor 20 in the vehicle width direction D2 is larger than the width L2 of the gap S. Therefore, even if the vehicle 100 comes into contact with an obstacle, the electric radiator fan motor 20 is pushed by the contact and does not enter the gap S, and the housing of the electric radiator fan motor 20 comes into contact with the housings of the first and second electric water pumps 30, 40. This prevents the electric radiator fan motor 20 from interfering with the first and second harness connectors 31, 41 of the first and second electric water pumps 30, 40. As a result, electrical failures such as electric leakage caused by damage to the first and second harness connectors 31, 41 can be prevented.

[0032] In this embodiment, as shown in FIG. 6 , the first electric water pump 30 and the second electric water pump 40 are disposed at approximately the same position in the fore-and-aft direction D1 of the vehicle 100. Therefore, the electric radiator fan motor 20 and the first and second electric water pumps 30, 40 interfere with each other in a substantially parallel manner. This prevents the harness connector 21 of the electric radiator fan motor 20 from interfering with the end faces 30a, 40a of the first and second electric water pumps 30, 40. As a result, electrical failures such as electric leakage caused by damage to the first and second harness connectors 31, 41 can be prevented. It is preferable that the first and second electric water pumps 30, 40 be disposed at the same position in the fore-and-aft direction D1 of the vehicle 100.

[0033] For example, in the case of the front body structure 1A according to Comparative Example 1, in which the first and second electric water pumps 30, 40 are positioned at significantly different positions in the fore-and-aft direction D1 of the vehicle 100, when the vehicle 100 (see FIG. 1) comes into contact with an obstacle, the electric radiator fan motor 20 may interfere with the electric radiator fan motor 20 from an oblique direction relative to the fore-and-aft direction D1, as shown in Fig. 10. In this case, the harness connector 21 of the electric radiator fan motor 20 may enter the gap S and interfere with the end faces 30a, 40a of the first and second electric water pumps 30, 40.

[0034] 6 , the first electric water pump 30 and the second electric water pump 40 are disposed at approximately the same position in the front-to-rear direction D1 of the vehicle 100. This prevents the harness connector 21 of the electric radiator fan motor 20 from interfering with the end faces 30 a, 40 a of the first and second electric water pumps 30, 40.

[0035] In addition, in this embodiment, the first and second harness connectors 31, 41, which are provided facing each other in the vehicle width direction, are disposed at different heights in the vehicle height direction D3 when viewed from the front of the vehicle 100. Therefore, when routing the first and second harness connectors 31, 41, the width L2 of the gap S in the vehicle width direction D2 can be reduced. This makes it difficult for other components, such as the harness connector 21 of the electric radiator fan motor 20, to enter the gap S, making it easier to protect the first and second harness connectors 31, 41. This reduces damage to the first and second harness connectors 31, 41 even when the vehicle 100 comes into contact with an obstacle ahead. As a result, electrical failures, such as electric leakage, caused by damage to the first and second harness connectors 31, 41 can be prevented.

[0036] For example, in the case of a front body structure 1B according to Comparative Example 2 shown in FIG. 11 , the first and second harness connectors 31, 41, which are arranged facing each other in the vehicle width direction, are disposed at the same height in the vehicle height direction D3 in a front view of the vehicle 100. In this case, it is necessary to ensure a width L2 (see FIGS. 6 and 7 ) of the gap S in the vehicle width direction D2 to prevent the first and second harness connectors 31, 41 from interfering with each other and to ensure space for connecting cables to the first and second harness connectors 31, 41. However, in the present embodiment, the first and second harness connectors 31, 41 are disposed at different heights in the vehicle height direction D3 in a front view of the vehicle 100, so the width L2 of the gap S in the vehicle width direction D2 can be reduced. This makes it difficult for other components, such as the harness connector 21 of the electric radiator fan motor 20, to enter the gap S, making it easier to protect the first and second harness connectors 31, 41. This makes it possible to suppress damage to the first and second harness connectors 31, 41 even when the vehicle 100 comes into contact with an obstacle ahead. As a result, it is possible to prevent electrical failures such as electric leakage caused by damage to the first and second harness connectors 31, 41.

[0037] 2 , in the present embodiment, the drive motor 50 serving as a drive source is provided behind the first electric water pump 30 and the second electric water pump 40. When the vehicle 100 collides head-on with an obstacle, the first and second electric water pumps 30, 40 apply force to the housing of the drive motor 50. This allows the force applied to the housing of the drive motor 50 to be dispersed more effectively than if the electric radiator fan motor 20 directly interferes with the housing of the drive motor 50, thereby preventing damage to the housing of the drive motor 50.

[0038] In this embodiment, as shown in FIG. 3 , a portion of the steering rack 60 is disposed so as to overlap the radiator fan shroud 11 in the fore-and-aft direction D1. Therefore, even if the vehicle 100 comes into contact with an obstacle, in addition to a first path through which an impact is transmitted from the electric radiator fan motor 20 to the first and second electric water pumps 30, 40, a second path is formed through which the impact is transmitted to the first and second electric water pumps 30, 40 via the steering rack 60. This allows the impact to be dispersed when the vehicle 100 comes into contact with an obstacle, compared to a case in which the impact is transmitted only through either the first path or the second path. As a result, electrical failures such as electric leakage caused by damage to the first and second harness connectors 31, 41 can be prevented.

[0039] Although the present embodiment has been described above, the present invention is not limited to the above embodiment.

[0040] For example, in this embodiment, as shown in FIGS. 4 and 5 , the first harness connector 31 has an opening 33 that opens in an opening direction Y1 (−Y direction). The second harness connector 41 has an opening 43 that opens in an opening direction Y2 (+Y direction), which is the opposite direction to the opening direction Y1. As a result, the first harness connector 31 and the second harness connector 41 face each other in the vehicle width direction D2. However, this is not limited to this. The first harness connector 31 and the second harness connector 41 do not have to face each other in the vehicle width direction D2. For example, as in the front body structure 2 according to Modification 1 shown in FIG. 12 , the opening 33 of the first harness connector 31 may be open upward (+Z direction), which is a direction other than the −Y direction. Furthermore, the opening 43 of the second harness connector 41 may be open in a direction other than the +Y direction.

[0041] In addition, in this embodiment, as shown in FIG. 4 , the harness 32 connected to the first harness connector 31 is pulled downward (in the −Z direction), bent at the bend 32 a, and extended upward. However, this is not limited to this. For example, as in the front body structure 3 according to Modification 2 shown in FIG. 13 , the harness 32 connected to the first harness connector 31 may be pulled directly upward (in the +Z direction) without being pulled downward (in the −Z direction). However, from the viewpoint of reducing the width of the gap S in the vehicle width direction D2, it is preferable that the harness 32 connected to the first harness connector 31 is first pulled downward (in the −Z direction).

[0042] In addition, in this embodiment, as shown in FIG. 6 , the second electric water pump 40 is disposed slightly rearward of the first electric water pump 30 in the front-to-rear direction D1. However, this is not limited to this. The second electric water pump 40 may be disposed at approximately the same position in the front-to-rear direction D1 of the vehicle 100. For example, the second electric water pump 40 may be disposed at exactly the same position in the front-to-rear direction D1 as the first electric water pump 30. Here, "approximately the same position" refers to a position where the second electric water pump 40 overlaps the first electric water pump 30 to the extent that it overlaps with the first electric water pump 30 in the vehicle width direction D2 of the vehicle 100.

[0043] As shown in Figure 2, the drive motor 50 is provided behind both the first electric water pump 30 and the second electric water pump 40. However, this is not limiting. The drive motor 50 may be provided behind either the first electric water pump 30 or the second electric water pump 40.

[0044] As shown in Fig. 3 , a portion of the steering rack 60 is disposed so as to overlap the radiator fan shroud 11 in the front-to-rear direction D1. However, this is not limited to this. One of the steering rack 60 and the electrical components of the electric power steering device 70 may be disposed so as to overlap the radiator fan shroud 11 in the front-to-rear direction D1. Furthermore, both the steering rack 60 and the electrical components of the electric power steering device 70 may be disposed so as to overlap the radiator fan shroud 11 in the front-to-rear direction D1. Furthermore, it is sufficient that at least one of the multiple electrical components of the electric power steering device 70 is disposed so as to overlap in the front-to-rear direction D1.

[0045] The present invention allows various embodiments and modifications without departing from the broad spirit and scope of the present invention. Furthermore, the above-described embodiments are intended to explain the present invention and do not limit the scope of the present invention. In other words, the scope of the present invention is defined by the claims, not by the embodiments. Various modifications made within the scope of the claims and the meaning of the disclosure equivalent thereto are considered to be within the scope of the present invention.
