Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hood device for a vehicle that absorbs an impact by sufficiently securing a deformation amount of the hood by lifting the hood.
[0002]
[Prior art]
Among vehicle hood devices, when a traveling vehicle collides with an obstacle, a hood is lifted by a predetermined amount and held at the lifted position. By lifting the hood, the amount of downward deformation can be increased, and the amount of collision energy absorbed can be increased. As this type of vehicle hood device, for example, Japanese Patent Application Laid-Open No. 10-258774 “Flip-up hood” is known, and this technique will be described in the following figure.
[0003]
FIG. 10 is a side view of a conventional vehicle hood device, showing a state in which the hood is closed.
The vehicle hood apparatus 100 has a bracket 102 attached to a vehicle body 101, a guide hole 102a is formed in the bracket 102, a lower end of a link 105 is attached to the guide hole 102a with a lower pin 103, and an upper end of the link 105 is attached to a hood with an upper pin 106. It is connected to the arm 107.
[0004]
A lock piece 111 is attached to the bracket 102 with a fixing pin 110, a tension spring 114 is applied to the lock piece 111, and a claw 112 of the lock piece 111 is pressed against the upper pin 106 by the spring force of the tension spring 114.
As a result, the upper pin 106 can be held in the U-shaped groove 102b of the bracket 102, and the link 105 can be prevented from rising. By preventing the link 105 from rising, the hood 108 can be prevented from being lifted at normal times, and the hood 108 can be prevented from rattling.
[0005]
On the other hand, when the vehicle collides with an obstacle, the claw 112 of the lock piece 111 is removed from the upper pin 106 to make the link 105 free, whereby the hood 108 can be lifted to a predetermined lifting position. Next, an example of lifting the hood 108 will be described.
[0006]
FIG. 11 is an operation explanatory view of a conventional vehicle hood device, and shows a state in which the hood is lifted.
When the vehicle collides with an obstacle, an actuator (not shown) is activated and a lifting force is applied to the hood 108. At the same time, an unlocking force F is applied to the lock piece 111 as shown by the arrow, and the lock piece 111 is rotated about the fixing pin 110 as shown by the arrow a. The claw 112 of the lock piece 111 comes off from the upper pin 106, and the link 105 becomes free.
[0007]
For this reason, the upper pin 106 ascends as shown by the arrow b along with the hood 108 and the lower pin 103 moves along the guide hole 102a as shown by the arrow c. As a result, the hood 108 is lifted by a predetermined amount, the amount of deformation of the hood 108 that can be deformed downward is increased, and the amount of collision energy absorbed can be increased.
[0008]
[Problems to be solved by the invention]
However, the upper pin 106 must be locked by the claw 112 of the lock piece 111 in order to eliminate the shakiness of the hood 108 at the normal time. Therefore, the lock piece 111 and the tension spring 114 that holds the lock piece 111 in the lock position are necessary.
On the other hand, in order to lift the hood 108 when the vehicle collides, the lock piece 111 at the lock position must be operated to the unlock position. For this reason, an operation mechanism for operating the lock piece 111 to the unlocked state is required.
Therefore, the number of parts of the vehicle hood apparatus 100 increases, which causes an increase in cost.
[0009]
Therefore, an object of the present invention is to provide a vehicle hood apparatus that can reduce the number of parts and suppress an increase in cost.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the first aspect of the present invention provides a swingable attachment of the first link to the bracket on the vehicle body via a pin, and a swingable attachment of the second link to the first link via a connecting pin. A hood at the front of the vehicle is attached to the second link via a hinge pin. Normally, the hood is opened and closed with the hinge pin connecting the second link and the hood as the hinge center. When an obstacle collides with the vehicle, In a hood device for a vehicle equipped with a hinge that also serves as a connecting link mechanism, the hood is lifted by the first and second links that are lifted and extended. In the second link, the stopper pin has a strength that does not cut. The middle part of By connecting to the bracket, the hood is prevented from rising during normal times.
[0011]
By connecting the second link to the bracket with a stopper pin, the hood can be prevented from rising during normal operation. By simply providing a stopper pin, it is possible to prevent rattling due to the hood floating. Accordingly, rattling due to the lift of the hood can be prevented with a simple configuration, and the number of parts can be reduced.
[0012]
By the way, according to the prior art, when the connecting link is extended, it is necessary to release the lock by the operation mechanism. For this reason, an operation mechanism is required as a dedicated member for unlocking, and the number of parts increases.
In this respect, since the lock is released by cutting the stopper pin with the lifting force when the actuator is operated, a special operation mechanism for releasing the lock becomes unnecessary. Therefore, the number of parts can be further reduced.
[0013]

[0025]
Next, an example of the assembly procedure of the hinge means 30 will be described based on FIG.
First, the pin 55 is inserted into the lower hole of the first link 50, and the pin 55 is inserted into the hole 37 a of the lower bracket 31 and crimped. Thus, the first link 50 is attached to the lower bracket 31 so as to be swingable.
Next, the hinge pin 68 is inserted into the hole 43a of the upper bracket 41, and the hinge pin 68 is inserted into the upper hole 61b of the second link 60 and tightened. Thus, the second link 60 is attached to the upper bracket 41 so as to be swingable.
[0026]
Next, the first link 50 and the second link 60 are connected by the connecting pin 66 and the connecting pin 66 is crimped. Thereby, the 1st link 50 and the 2nd link 60 are connected so that swing is possible mutually. Subsequently, the stopper pin 40 is inserted into the stopper hole 39a of the lower bracket 31 and the stopper hole 63 of the second link 60, and the stopper pin 40 is crimped. Thereby, the second link 60 is connected to the lower bracket 31 by the stopper pin 40.
[0027]
In this manner, with the first and second links 50 and 60 and the upper bracket 41 being assembled to the lower bracket 31, the lower bracket 31 is attached to the vehicle body frame 17 (shown in FIG. 2) with the bolts 32 and 32.
Finally, the upper bracket 41 is attached to the hood 21 (shown in FIG. 2) with bolts 42 and 42. This completes the assembly of the hinge means 30.
[0028]
In the folded state of the first and second links 50 and 60 shown in FIG. 2, the hinge means 30 can be in a state where the mounting portion 64 of the second link 60 is mounted on the first stopper 38 a of the lower bracket 31. . For this reason, the downward movement of the second link 60 can be regulated by the first stopper 38a, and the hood 21 can be supported in a stable state.
[0029]
Further, the hinge means 30 forms the first and second links 50 and 60 shown in FIG. 2 in a substantially L shape so that the second link 60 is aligned with the inclined portion 31a of the lower bracket 31 and the first link. 50 can be attached separately from the inclined portion 31a. Thereby, the place provided with the stopper pin 40 in the inclination part 31a vicinity can be ensured.
[0030]
Furthermore, the hinge means 30 can incline the 2nd link 60 downward toward the vehicle front by arrange | positioning the 2nd link 60 along the inclination part 31a of the lower link 31, as shown in FIG. . For this reason, the pin 55 attachment position of the lower bracket 31 can be set to a relatively high position from the vehicle body frame 17 (shown in FIG. 2).
Thereby, the shape of the lower bracket 31 can be determined so that it may be easily crushed when an obstacle hits the hood 21. The shape of the lower bracket 31 will be described in detail with reference to FIG.
[0031]
4 (a) and 4 (b) are cross-sectional views of the hood device for a vehicle according to the present invention. (A) is a cross-sectional view taken along the line 4 (a)-(a) of FIG. 4 (b)-(b) is a cross-sectional view.
(A) shows the state which attached the 1st link 50 to the 4th bending part 37 of the lower bracket 31 with the pin 55, and attached the 2nd link 60 to the upper bracket 41 with the hinge pin 68. FIG.
The lower bracket 31 is a member formed of, for example, mild steel, and the second bent portion 35, the third bent portion 36, and the fourth bent portion 37 are bent into a substantially inverted U shape so as to be easily crushed. For this reason, when a load from above is applied to the lower bracket 31, the second bent portion 35, the third bent portion 36, and the fourth bent portion 37 can be crushed to absorb the impact.
[0032]
(B) shows a state in which the stopper pin 40 is inserted into the stopper hole 39a of the lower bracket 31 and the stopper hole 63 of the second link 60 and the stopper pin 40 is crimped. The stopper pin 40 has a strength that is cut when the actuator 24 (shown in FIG. 2) is operated but is not cut by a normal hood opening / closing force.
Therefore, by connecting the second link 60 to the lower bracket 31 with the stopper pin 40, the first and second links 50, 60 can be prevented from extending, and the hood 21 can be prevented from rising in the normal state.
By only providing the stopper pin 40, for example, rattling due to the lift of the hood 21 during traveling of the vehicle can be prevented, so that the number of parts can be reduced.
[0033]
On the other hand, when the actuator 24 (shown in FIG. 2) is actuated, the stopper pin 40 can be disconnected by the lifting force of the actuator 24 to release the state where the second link 60 is connected to the lower bracket 31. The operation mechanism for unlocking the prior art can be omitted. For this reason, the number of parts can be further reduced.
[0034]
5 (a) to 5 (c) are explanatory diagrams for explaining the procedure for assembling the stopper pin constituting the vehicle hood apparatus according to the present invention.
In (a), the stopper pin 40 is inserted into the stopper hole 39a of the lower bracket 31 and the stopper hole 63 of the second link 60 as shown by an arrow.
In (b), the head and tip of the stopper pin 40 are sandwiched by the crimping device 80, and a load is applied as indicated by the white arrow to crush the tip of the stopper pin 40.
In (c), the stopper pin 40 is prevented from coming off at the crushing portion 40 c of the stopper pin 40.
[0035]
Here, the stopper pin 40 includes a large-diameter portion 40a and a small-diameter portion 40b, and is formed so as to be easily cut by the step portion 40d. In this stopper pin 40, the large-diameter portion 40 a is inserted into the stopper hole 39 a and the small-diameter portion 40 b is inserted into the stopper hole 63, so that the step portion 40 d is disposed at the boundary between the lower bracket 31 and the second link 60. Therefore, when the actuator 24 is actuated, the stopper pin 40 can be reliably cut by the step portion 40d.
[0036]
FIGS. 6A and 6B are first operation explanatory views of the vehicle hood apparatus according to the present invention, and an example in which the hood is opened for engine room repair and inspection will be described.
In (a), by inserting the stopper pin 40 into the stopper hole 39a (shown in FIG. 5) of the lower bracket 31 and the stopper hole 63 (shown in FIG. 5) of the second link 60, the first and second links 50, 60 is kept in a folded state, and in this state, the hood lock mechanism 22 (shown in FIG. 1) at the front of the hood 21 is released, and the hinge pin 68 on the rear end side of the hood 21 is used as an axis as indicated by the arrow (1). Open.
[0037]
In (b), by opening the hood 21 to the fully open position, the stopper 44 of the upper bracket 41 hits the first stopper 38a of the lower bracket 31 and restricts further opening of the hood 21. In this case, a force acts to rotate the second link 60 in the clockwise direction about the hinge pin 68 as an axis, but the stopper pin 40 is inserted into the stopper holes 39a and 63 (shown in FIG. 5), so that the second The rotation of the link 60 can be prevented.
By opening the hood 21, the equipment in the engine room can be maintained and inspected from above.
[0038]
Next, the operation of the vehicle hood device 20 will be described.
First, referring back to FIG. 1, when the vehicle 10 collides with the obstacle 18 while traveling, the bumper sensor 26 detects the collision and transmits a detection signal from the sensor 26 to the control unit 29. A drive signal is transmitted from the control unit 29 to the actuator 24, and a gas pressure is applied to the actuator 24 so as to project the rod 25. When the gas pressure acts on the rod 25 of the actuator 24, the rod 25 is instantaneously raised by the gas pressure, and the lifting force of F1 is applied to the hood 21 as shown by the arrow.
[0039]
Next, as shown in FIG. 4B, by applying a lifting force of F1 to the hood 21, the upper bracket 41, the hinge pin 68 (shown in FIG. 4A), and the stopper hole 63 of the second link 60 are used. Thus, a force F2 is applied to lift the small diameter portion 40b of the stopper pin 40 upward. Thereby, the stopper pin 40 is cut | disconnected by the step part 40d.
[0040]
FIGS. 7A and 7B are explanatory views of a second action of the vehicle hood device according to the present invention, and FIG. 7B is a sectional view taken along line bb in FIG.
In (a), when the stopper pin 40 is cut, the second link 60 swings counterclockwise about the connecting pin 66, and at the same time, the first link 50 rotates clockwise about the pin 55. To swing.
Accordingly, when the first and second links 50 and 60 start to expand, the hood 21 is raised as shown by the arrow (2) with the hood lock mechanism 22 (shown in FIG. 1) as an axis.
(B) shows the state in which the stopper pin 40 is cut at the stepped portion 40d.
[0041]
FIG. 8 is an explanatory view of the third action of the vehicle hood apparatus according to the present invention.
The first and second links 50 and 60 extend so that the pin 55, the connecting pin 66 and the hinge pin 68 are positioned on the straight line 70. Thereby, the raising of the hood 21 is regulated by the first and second links 50 and 60, and the hood 21 is stopped at the upper limit position P1.
[0042]
After the hood 21 comes to rest, the hood tries to descend by its own weight. Therefore, the weight of the hood 21 is applied to the first and second links 50 and 60, and the first and second links 50 and 60 are to be folded.
However, since the pin 55, the connecting pin 66 and the hinge pin 68 are located on the straight line 70, the first and second links 50 and 60 are not folded even if the hood 21 is subjected to its own weight. For this reason, the hood 21 can be held by the first and second links 50 and 60.
[0043]
In this state, when the obstacle 18 falls on the hood 21, an external force F3 is applied as shown by an arrow. As a result, a force is exerted to cause the first link 50 to fall backward with the pin 55 as an axis, but the first link 50 is applied to the second stopper 38b of the lower bracket 31 by applying the stopper 53 of the first link 50 to the first link 50. 50 can be prevented from falling to the rear of the vehicle.
[0044]
At the same time, a force is applied to try to tilt the second link 60 forward with the connecting pin 66 as an axis, but the second link 60 is moved forward with the stopper 62 of the second link 60 against the first link 50. Can be prevented from falling.
Therefore, since the first and second links 50 and 60 can be maintained in the extended state, the hood 21 can be held at the upper limit position P <b> 1 lifted by a predetermined amount by the hinge means 30.
[0045]
FIG. 9 is a diagram illustrating a fourth function of the vehicle hood apparatus according to the present invention.
By lifting the hood 21 by a predetermined amount from the position indicated by the imaginary line to the position indicated by the solid line, the distance from the hood 21 to the device 19 such as the engine housed in the engine room 14 can be increased. Therefore, a sufficient amount of downward deformation of the hood 21 can be ensured.
For this reason, even if the obstacle 18 falls on the hood 21 and an external force F3 is applied as shown by an arrow, the recessed portion 21a of the hood 21 can be secured large as shown by an imaginary line. Therefore, the impact on the obstacle 18 can be reliably absorbed.
[0046]
In addition, as shown in FIG. 4A, the second bent portion 35, the third bent portion 36, and the fourth bent portion 37 of the lower bracket 31 are bent into a substantially inverted U-shape so that they are easily crushed. Therefore, when the obstacle 18 falls on the hood 21 and an external force F3 is applied as shown by an arrow, the second bent portion 35, the third bent portion 36, and the fourth bent portion 37 are crushed to absorb the impact. be able to. Therefore, the impact on the obstacle 18 can be absorbed more reliably.
[0047]
Further, even if the amount of depression of the dent 21a generated in the hood 21 is increased as indicated by an imaginary line, the dent 21a does not hit the equipment 19 in the engine room, so that the equipment 19 is protected from the obstacle 18. Can do.
[0048]
In the above-described embodiment, the example in which the projecting piece 39 is provided on the inclined portion of the lower bracket 31 and the stopper pin 40 is formed on the projecting piece 39 has been described, but the arrangement location of the stopper pin 40 may be arbitrarily set. Good.
Further, as an example of connecting the second link 60 to the lower bracket 31, the example in which the stopper pin 40 is inserted into the stopper hole 63 of the second link 60 has been described. You may make it insert in the stopper hole of this link.
Furthermore, in the said embodiment, although the example which formed the lower bracket 31 with mild steel was demonstrated, material is not restricted to this.
[0049]
In the above embodiment, an example in which two actuators 24 and two hinge means 30 are respectively attached to the left and right sides of the vehicle body frame 17 has been described. However, the actuator 24 and the hinge means 30 may be attached only to one side of the vehicle body frame 17. . As a result, the number of parts can be further reduced to further suppress the cost increase.
Moreover, although the actuator 24 was attached to the vehicle body frame 17, you may attach the actuator 24 to the hood 21 side, for example.
[0050]
Further, in the above-described embodiment, the example in which the hood 21 is lifted by the rod 25 of the actuator 24 until the hood 21 reaches the upper limit position P1 has been described. Also good. Since the stroke of the rod 25 can be reduced, the actuator 24 can be downsized.
[0051]
【The invention's effect】
The present invention exhibits the following effects by the above configuration.
Claim 1 is the second link The middle part of By connecting to the bracket with a stopper pin, the hood can be prevented from rising during normal operation. By simply providing a stopper pin, it is possible to prevent rattling due to the hood floating. Therefore, rattling due to the lift of the hood with a simple configuration The Since it can prevent, the number of parts can be reduced.
[0052]
Further, when the actuator is operated, the stopper pin is cut by the lifting force to release the lock, so that a special operation mechanism for releasing the lock becomes unnecessary. Therefore, the configuration can be simplified and the number of parts can be further reduced. Therefore, the cost increase of the vehicle hood device can be suppressed.
[0053]
In addition, by reducing the number of parts, the device for preventing rattling of the hood can be reduced in size, thereby increasing the degree of freedom in design.
Furthermore, the assembly work can be simplified by reducing the number of parts.
