[ peripheral Structure of cab rear cover 7 ]
Fig. 1A and 1B are diagrams illustrating a state of a vehicle provided with a cab back cover 7 according to the present embodiment. Fig. 1A is a sectional view of a vehicle provided with a cab back cover 7 of the present embodiment. Fig. 1B is a view showing a state of the vehicle in which the cab back 7 of the present embodiment is viewed from below. Fig. 2 is a diagram showing the structure of cab 1 as viewed from the rear. Fig. 3 is a diagram showing a state in the vicinity of the cab back cover 7 in the vehicle provided with the cab back cover 7 of the present embodiment.
The vehicle is a flat-head vehicle, such as a truck. The vehicle has a cab 1, a mount 2, side frames 3, an engine 4, a fan 5, a radiator 6, and a cab rear cover 7.
Cab 1 is, for example, a box-shaped portion provided with a driver's seat, and is provided in front of the vehicle. The cab 1 is provided, for example, above the side frames 3 in the vehicle height direction. As shown in fig. 1A, 1B, and 2, a recess 11 is formed at a lower end of a rear surface of cab 1. A cab rear cover 7, which will be described later, is provided behind the recess 11 of the cab 1.
The rack unit 2 is a box-shaped portion that accommodates, for example, cargo, and is provided behind the cab 1. The rack mount 2 is provided, for example, above the side frames 3 in the vehicle height direction.
The side frames 3 are members extending in the front-rear direction of the vehicle. Two side frames 3 are arranged in parallel. The engine 4 generates power for driving the vehicle. The engine 4 is, for example, a gasoline engine or a diesel engine. The engine 4 generates power and exhaust gas by increasing the temperature of fuel (e.g., gasoline or light oil) by combustion with air. Engine 4 is disposed below cab 1. The engine 4 is disposed rearward of the fan 5 in the front-rear direction of the vehicle.
The fan 5 is a blower for flowing air. The fan 5 is connected to the engine 4 via a shaft, for example, and is rotationally driven by receiving power from the engine 4. The fan 5 causes air to flow from the front to the rear in the front-rear direction of the vehicle. Fan 5 is disposed below cab 1. The fan 5 is disposed forward of the engine 4 and rearward of the radiator 6 in the front-rear direction of the vehicle.
The radiator 6 cools engine cooling water for cooling the engine 4. Engine cooling water circulates between the radiator 6 and the engine 4. The radiator 6 is cooled by engine cooling water that has been heated by flowing through the engine 4.
The air flowing out from the air flow outlet on the rear surface of the radiator 6 takes away the heat of the engine cooling water heated by the engine 4 in the radiator 6, and the temperature thereof rises as compared with the air flowing into the air flow inlet on the front surface of the radiator 6. The air flowing out of the air outlet of the radiator 6 flows rearward. Specifically, the air flowing out of the air outlet on the rear surface of the radiator 6 passes through the fan 5, flows around the engine 4, and flows into the cab rear cover 7 from the inside of the recess 11 on the rear surface of the cab 1.
The air flowing into the inside of the cab back 7 is heated by depriving the radiator 6 of heat of the engine cooling water heated by the engine 4, and further heated by the engine 4 by flowing around the engine 4, so that the temperature of the air rises as compared with the air before flowing into the radiator 6.
The cab back cover 7 suppresses transmission of noise generated by operation of the engine 4 to the surroundings, improves the rear appearance of the cab 1, and suppresses the heated air from flowing around in a scattered manner, for example. As shown in fig. 1A, 1B, and 3, a cab rear cover 7 is provided behind the cab 1. Specifically, for example, cab rear cover 7 is provided on the rear surface of cab 1 so as to cover recess 11.
The cab back cover 7 allows air heated by the radiator 6 and the engine 4 to flow in from the front, suppresses upward, rearward, leftward, and rightward flows, and allows the air to flow out downward. As a result, the cab back 7 can flow the air heated by the radiator 6 and the engine 4 to the lower side of the vehicle, for example, the lower side of the mount 2, and therefore the heated air can be prevented from flowing around without being scattered.
[ Structure of cab rear cover 7 ]
Fig. 4 is a diagram showing the structure of the cab back cover 7 of the present embodiment. Fig. 5 is a view showing a structure in the vicinity of the right side surface portion 74 when the cab back cover 7 shown in fig. 4 is viewed from the a direction. Fig. 6A and 6B are sectional views of the cab back cover 7 shown in fig. 4. Fig. 6A is an X-X sectional view of the cab back cover 7 shown in fig. 4. Fig. 6B is a cross-sectional view of the cab back cover 7 shown in fig. 4 taken along line Y-Y.
The cab rear cover 7 has an upper surface portion 71, a rear surface portion 72, a left side surface portion 73, and a right side surface portion 74. The upper surface portion 71 suppresses upward outflow of air flowing from the front. The upper surface portion 71 is plate-shaped, for example. As shown in fig. 1A, 1B, and 3, the front end of upper surface portion 71 is fixed to, for example, the vicinity of the upper end of recess 11 in the rear surface of cab 1. Specifically, the front end of upper surface portion 71 is fixed to the rear surface of cab 1 in contact with the rear surface of cab 1.
The upper surface portion 71 has a first upper surface area 711 and a second upper surface area 712. The first upper surface area 711 is an area extending downward in the height direction of the vehicle from the front to the rear at a third angle with respect to the horizontal direction orthogonal to the height direction of the vehicle. The second upper surface area 712 is connected to the rear end of the first upper surface area 711, and extends downward in the vehicle height direction from the front to the rear at a fourth angle larger than the third angle with respect to the horizontal direction orthogonal to the vehicle height direction.
The rear surface portion 72 suppresses the backward flow of the air flowing in from the front. Specifically, the rear surface portion 72 has a flat plate shape, for example, and extends in the height direction of the vehicle.
The left side surface 73 suppresses the air flowing in from the front from flowing out to the left. The left side surface 73 is plate-shaped, for example. The front end of the left side surface 73 is fixed to the vicinity of the left end of the recess 11 in the rear surface of the cab 1, for example. The left side surface 73 has a front region 731 and a rear region 732.
The front region 731 is a region extending from the front to the rear and inward in the vehicle width direction of the vehicle at a first angle with respect to the front-rear direction of the vehicle. The first angle is, for example, an angle of draft when the cab back cover 7 is molded, and is 10 degrees or less. Specifically, the front region 731 is a region extending from the front to the rear and to the right in the vehicle width direction of the vehicle at a first angle with respect to the front-rear direction of the vehicle.
The rear region 732 is connected to the rear end of the front region 731, and extends from the front to the rear, and inward in the vehicle width direction of the vehicle at a second angle larger than the first angle with respect to the front-rear direction of the vehicle. Specifically, the rear region 732 is connected to the rear end of the front region 731, and extends from the front to the rear, and to the right in the vehicle width direction of the vehicle at a second angle larger than the first angle with respect to the front-rear direction of the vehicle.
The right side surface portion 74 suppresses the air flowing in from the front from flowing out to the right. The right side surface 74 is plate-shaped, for example. The front end of the right side surface portion 74 is fixed to the vicinity of the right end of the recess 11 in the rear surface of the cab 1, for example. Right side face 74 has a front region 741 and a rear region 742.
The front region 741 is a region extending from the front to the rear and inward in the vehicle width direction of the vehicle at a first angle with respect to the front-rear direction of the vehicle. Specifically, the front region 741 is a region extending from the front to the rear and to the left in the vehicle width direction of the vehicle at a first angle with respect to the front-rear direction of the vehicle.
The rear region 742 is a region that is connected to the rear end of the front region 741, extends from the front to the rear, and extends inward in the vehicle width direction of the vehicle at a second angle that is greater than the first angle with respect to the front-rear direction of the vehicle. Specifically, the rear region 742 is connected to the rear end of the front region 741, and is a region extending from the front to the rear and to the left in the vehicle width direction of the vehicle at a second angle greater than the first angle with respect to the front-rear direction of the vehicle.
Fig. 7 is a diagram showing the structure of a conventional cab rear cover 9. Fig. 8A and 8B are sectional views of the conventional cab back cover 9 shown in fig. 7. Fig. 8A is an X-X sectional view of the conventional cab rear cover 9 shown in fig. 7. Fig. 8B is a cross-sectional view of the conventional cab rear cover 9 shown in fig. 7 taken along line Y-Y.
The conventional cab rear cover 9 is different from the cab rear cover 7 of the present embodiment in that the left side surface portion 93 and the right side surface portion 94 have regions extending inward in the vehicle width direction of the vehicle from the front to the rear at a predetermined angle with respect to the front-rear direction of the vehicle, and do not have regions connected to the rear ends of the regions and extending inward in the vehicle width direction of the vehicle from the front to the rear at a predetermined angle larger than the predetermined angle with respect to the front-rear direction of the vehicle.
The conventional cab rear cover 9 includes an upper surface portion 91, a rear surface portion 92, a left side surface portion 93, and a right side surface portion 94. Like the upper surface portion 71, the upper surface portion 91 suppresses upward outflow of air flowing in from the front. Like the upper surface portion 71, the upper surface portion 91 has a first upper surface region 911 and a second upper surface region 912.
Like the first upper surface region 711, the first upper surface region 911 is a region extending downward in the height direction of the vehicle from the front direction rear at a third angle with respect to the horizontal direction orthogonal to the height direction of the vehicle. The second upper surface region 912 is connected to the rear end of the first upper surface region 911, and extends from the front to the rear and downward in the height direction of the vehicle at a fourth angle larger than the third angle with respect to the horizontal direction orthogonal to the height direction of the vehicle.
Similarly to the rear surface portion 72, the rear surface portion 92 suppresses the backward flow of the air flowing in from the front. The left side surface 93 suppresses the air flowing in from the front from flowing out to the left, similarly to the left side surface 73. The left side surface portion 93 has a region extending from the front to the rear and toward the inside in the vehicle width direction of the vehicle at, for example, a first angle with respect to the front-rear direction of the vehicle.
The right side surface portion 94, like the right side surface portion 74, suppresses the air flowing in from the front from flowing out to the right. The right side surface portion 94 has a region extending from the front to the rear, for example, toward the inside in the vehicle width direction of the vehicle at a first angle with respect to the front-rear direction of the vehicle.
As shown in fig. 8A and 8B, in the conventional cab back cover 9, a part of the heated air flowing into the cab back cover 9 from the front flows from the front to the rear along the inner surface of the left side surface portion 93. The heated air flowing from the front to the rear along the inner surface of the left side surface portion 93 hits the region near the end portion connected to the left side surface portion 93 in the rear surface portion 92. Similarly, a part of the heated air flowing into the cab back 9 from the front flows from the front to the rear along the inner side surface of the right side surface portion 94. The heated air flowing from the front to the rear along the inner surface of the right side surface portion 94 hits the region near the end portion connected to the right side surface portion 94 in the rear surface portion 92.
As a result, for example, a deposition area of heated air flowing from the front to the rear along the inner surface of the left side surface portion 93 is generated in the vicinity of the end portion of the inner side of the cab rear cover 9 connected to the left side surface portion 93 of the rear surface portion 92. Similarly, for example, a deposition region of heated air flowing from the front to the rear along the inner surface of the right side surface portion 94 is generated in the vicinity of the end portion of the inner side of the cab rear cover 9 connected to the right side surface portion 94 of the rear surface portion 92.
That is, the heated air flowing backward from the front direction along the inner surface of the left side surface portion 93 has a reduced flow velocity in the vicinity of the end portion of the inner side of the cab rear cover 9 connected to the left side surface portion 93 of the rear surface portion 92. Similarly, the flow velocity of the heated air flowing backward from the front direction along the inner surface of the right side surface portion 94 is reduced in the vicinity of the end portion of the inner side of the cab rear cover 9 connected to the right side surface portion 94 of the rear surface portion 92.
Therefore, the flow velocity of the heated air flowing into the cab back cover 9 is reduced inside the cab back cover 9, and the inside of the cab back cover 9 is filled. As a result, thermal damage may occur to components of the vehicle, for example, which are disposed below cab 1.
In contrast, as shown in fig. 6A and 6B, in the cab rear cover 7 of the present embodiment, as described above, the left side surface 73 has the front region 731 and the rear region 732, and the right side surface 74 has the front region 741 and the rear region 742.
Therefore, the heated air flowing from the front to the rear along the inner surface of the left side surface portion 73 flows along the front region 731 and the rear region 732 inside the cab rear cover 7, and then flows near the end connected to the rear region 732 of the rear surface portion 72.
The front region 731 extends inward in the vehicle width direction of the vehicle at a first angle with respect to the front-rear direction of the vehicle, and the rear region 732 extends inward in the vehicle width direction of the vehicle at a second angle greater than the first angle with respect to the front-rear direction of the vehicle. That is, the left side surface portion 73 gradually changes from a direction toward the front-rear direction of the vehicle to a direction toward the vehicle width direction of the vehicle from the front to the rear. Therefore, the heated air flowing from the front to the rear along the inner surface of the left side surface portion 73 is less likely to hit the rear surface portion 72 at an angle close to a right angle, and the flow velocity is less likely to decrease.
Similarly, inside the cab rear cover 7, the heated air flowing rearward from the front direction along the inner surface of the right side surface portion 74 flows along the front region 741 and the rear region 742, and then flows to the vicinity of the end portion connected to the rear region 742 of the rear surface portion 72.
The front region 741 extends inward in the vehicle width direction of the vehicle at a first angle with respect to the front-rear direction of the vehicle, and the rear region 742 extends inward in the vehicle width direction of the vehicle at a second angle greater than the first angle with respect to the front-rear direction of the vehicle. That is, the right side surface portion 74 gradually changes from a direction toward the front-rear direction of the vehicle to a direction toward the vehicle width direction of the vehicle from the front-rear direction. Therefore, the heated air flowing from the front to the rear along the inner surface of the right side surface portion 74 is less likely to hit the rear surface portion 72 at an angle close to a right angle, and the flow velocity is less likely to decrease.
Therefore, the flow velocity of the heated air flowing into the inside of the cab back cover 7 is not easily reduced inside the cab back cover 7, and the heated air flowing into the inside of the cab back cover 7 is not easily filled in the inside of the cab back cover 7. As a result, thermal damage to the vehicle components is less likely to occur.
Further, since the cab rear cover 7 includes the left side surface portion 73 having the front region 731 and the rear region 732, and the right side surface portion 74 having the front region 741 and the rear region 742, it is possible to suppress molding defects when the cab rear cover 7 is manufactured by press-molding using resin, for example. Specifically, for example, when the resin is pressurized using the lower mold and the upper mold, the left side surface portion 73 has the front region 731 and the rear region 732, and the right side surface portion 74 has the front region 741 and the rear region 742, so that when the resin is loaded on the upper surface of the lower mold, the resin easily flows along the upper surface of the lower mold, and molding failure can be suppressed.
In addition, the upper end of the front region 731 is connected to the left side end of the first upper surface region 711. In addition, the upper end of the front region 741 is connected to the right side end of the first upper surface region 711. The upper end of the rear region 732 is connected to the left end of the second upper surface region 712. The upper end of rear region 742 is connected to the right side end of second upper surface region 712.
The cab rear cover 7 has such a structure that, of the heated air flowing into the inside of the cab rear cover 7 from the front, the flow velocity of the heated air flowing from the front to the rear along the left side surface portion 73 and the flow velocity of the heated air flowing from the front to the rear along the right side surface portion 74 are less likely to decrease, and the flow velocity of the heated air flowing from the front to the rear along the upper surface portion 71 is less likely to decrease. As a result, the flow speed of the heated air flowing from the front into the inside of the cab back cover 7 is less likely to decrease inside the cab back cover 7.
In the above embodiment, the example in which the cab rear cover 7 includes the left side surface 73 having the front region 731 and the rear region 732, and the right side surface 74 having the front region 741 and the rear region 742 is illustrated, but the present invention is not limited to this. The cab back cover 7 may have a structure in which at least one of the left side surface 73 and the right side surface 74 has a front region and a rear region.
In the above-described embodiment, the front region extends from the front to the rear and inward in the vehicle width direction of the vehicle at the first angle with respect to the front-rear direction of the vehicle, but the present invention is not limited to this. The front region may also extend in the front-rear direction of the vehicle.
In the above-described embodiment, the front region 731, the rear region 732, the front region 741, and the rear region 742 are all planar, but the present invention is not limited thereto. The front region 731, the rear region 732, the front region 741, and the rear region 742 may all be curved surfaces.
[ Effect of cab rear cover 7 of the present embodiment ]
The cab rear cover 7 of the present embodiment is a cab rear cover 7 provided behind the cab 1 of the vehicle, and includes: an upper surface portion 71 that suppresses upward outflow of air flowing in from the front; a rear surface portion 72 that suppresses the backward flow of air flowing in from the front; a left side surface 73 that suppresses the air flowing in from the front from flowing out to the left; and a right side surface portion 74 that suppresses the air flowing in from the front from flowing out to the right.
At least one of the left side surface 73 and the right side surface 74 includes: a front region extending from the front to the rear and inward in the vehicle width direction of the vehicle at a first angle with respect to the front-rear direction of the vehicle; and a rear region connected to a rear end of the front region, extending from the front to the rear, and inward in the vehicle width direction of the vehicle at a second angle greater than the first angle with respect to the front-rear direction of the vehicle.
In the cab back cover 7 of the present embodiment, at least one of the left side surface 73 and the right side surface 74 includes: a front region extending from the front to the rear and inward in the vehicle width direction of the vehicle at a first angle with respect to the front-rear direction of the vehicle; and a rear region connected to a rear end of the front region, extending from the front to the rear, and inward in the vehicle width direction of the vehicle at a second angle greater than the first angle with respect to the front-rear direction of the vehicle.
The cab back cover 7 has the above-described configuration, so that the flow velocity of the heated air flowing from the front to the rear along the left side surface portion 73 and the flow velocity of the heated air flowing from the front to the rear along the right side surface portion 74 are less likely to decrease inside the cab back cover 7. Therefore, the cab back cover 7 makes it difficult to reduce the flow rate of the heated air inside the cab back cover 7, so that it is possible to make it difficult for the heated air flowing in from the front to fill the inside of the cab back cover 7. As a result, the cab back cover 7 can thermally damage components of the vehicle.
The present disclosure has been described above with reference to the embodiments, but the technical scope of the present disclosure is not limited to the scope described in the above embodiments, and various modifications and changes can be made within the scope of the present disclosure. For example, the specific embodiments of the separation and integration device are not limited to the above-described embodiments, and all or a part of the devices may be configured by functionally or physically separating and integrating the devices in arbitrary units. In addition, a new embodiment which is generated by arbitrary combination of the plurality of embodiments is also included in the embodiments of the present disclosure. The effects of the new embodiment produced by the combination also have the effects of the original embodiment.
