It is obvious that the described embodiments are used for explaining the technical solution of the present invention, and do not mean that all embodiments of the present invention have been exhaustively exhausted.
Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
Referring to fig. 1 to 5, the present invention first discloses an active hinge for an engine cover, which mainly includes a fixed base 1, a rotating arm 2, a rotating arm bracket 3, a telescopic support 4, a vibration exciter 5, and other components. Fig. 1 and 2 show the closed state of the active hinge, fig. 3 and 4 show the actively sprung state of the active hinge, and fig. 5 shows the open state of the active hinge.
Referring to fig. 1 and 2, the fixing base 1 is an elongated member having a first end 11 and a second end 12 along a length direction. As shown in fig. 1, the first end 11 of the fixing base 1 is located at the end of the fixing base 1 in the length direction, and the second end 12 of the fixing base 1 is located in the middle area of the fixing base 1 in the length direction. Two fixing holes 13 are formed in the center of the fixing base 1, and fixing members (such as bolts, etc., not shown in the drawings) are inserted into the two fixing holes 13, so that the fixing base 1 is fixedly connected to the vehicle frame.
As a preferred embodiment of the present invention, a part of the edge of the fixing base 1 in the length direction may be folded along one side of the fixing base 1 to form an inner region of the fixing base 1. As shown in fig. 1, the upper edge of the fixing base 1 in the length direction and the lower edge near the first end position are both folded towards the direction away from other components, so that an inner area of the fixing base 1 is formed on one side of the fixing base 1. Similarly, the side of the fixing base 1 opposite to the inner area is the outer area. The intermediate position of the fastening base 1 is fixedly connected to a cross beam of the vehicle frame by means of a fastening element, so that the cross beam of the vehicle frame is nested in the interior region of the fastening base 1.
With continued reference to fig. 1 and 2, the rotating arm 2 is an elongated member having a first end 21 and a second end 22 along its length. As shown in fig. 2, the first end 21 of the rotating arm 2 is located at one end of the rotating arm 2 in the length direction, and the second end 22 of the rotating arm 2 is located at the other end of the rotating arm 2 in the length direction. As shown in fig. 2, the upper edge of the rotating arm 2 in the length direction is folded along one side of the rotating arm 2, forming a support edge 23 for supporting a flange 31 of the rotating arm bracket 3.
In a preferred embodiment of the present invention, one side edge of the rotating arm 2 in the longitudinal direction is folded along one side of the rotating arm 2 to form an internal region of the rotating arm 2. Similarly, the side of the rotary arm 2 opposite the inner region is the outer region. As can be seen from a comparison of fig. 1 and 2, the outer region of the rotating arm 2 is opposite to the outer region of the stationary base 1, and the inner region of the rotating arm 2 is opposite to the inner region of the stationary base 1. A portion of the lower edge of the rotary arm 2 in the longitudinal direction, at a location 24 near the first end of the rotary arm 2, is also folded over along one side of the rotary arm 2, forming the aforementioned inner region. It will be appreciated by those skilled in the art that the configuration of the internal region thus formed is folded to enhance the rigidity and resistance to twisting of the pivot arm 2.
As can be seen from fig. 1 and 2, the fixed base 1 and the rotating arm 2 are connected by a pin 14, such that the first end 21 of the rotating arm 2 is hinged to the first end 11 of the fixed base 1 and forms a rotation axis a, such that the rotating arm 2 can rotate around the rotation axis a relative to the fixed base 1, as shown in fig. 3-5. Those skilled in the art can understand that the pin connection is only one of many connection manners of the fixed base 1 and the rotating arm 2, and in other embodiments of the present invention, the fixed base 1 and the rotating arm 2 may also be connected in other reasonable manners, so as to realize the relative rotation motion between the fixed base 1 and the rotating arm 2.
As can be seen from fig. 1 and 2, when the active hinge is in the closed state, the fixed base 1 and the rotating arm 2 are parallel to each other and are located on the same horizontal plane. As can be seen from fig. 3 and 4, when the rotating arm 2 rotates around the rotation axis a relative to the fixed base 1, the second end of the rotating arm 2 is lifted upward and away from the second end of the fixed base 1.
With continued reference to fig. 1 and 2, the swivel arm bracket 3 comprises a flange 31, a connecting edge 32 and an extension end 33, the flange 31 of the swivel arm bracket 3 is adapted to be fixedly connected to the engine hood 6, the connecting edge 32 is adapted to be fixedly connected to the swivel arm 2, in particular to the second end 22 of the swivel arm 2, and the extension end 33 extends forward beyond the swivel arm 2 along the length of the swivel arm 2. In the closed state as shown in fig. 1 and 2, the flange 31 abuts and rests against the upper surface of the support rim 23 of the rotary arm 2, while in the actively sprung state as shown in fig. 3 and 4, the rotary arm support 3 is lifted upwards, so that the flange 31 of the rotary arm support 3 and the support rim 23 of the rotary arm 2 are disengaged from each other. In the open position shown in fig. 5, the flange 31 of the pivot arm carrier 3 also rests against the upper surface of the support edge 23 of the pivot arm 2.
As a preferred embodiment of the present invention, as shown in fig. 1 and fig. 2, the rotating arm support 3 is substantially in the shape of a folded angle part, two edges of the folded angle are a turned edge 31 and a connecting edge 32, respectively, the turned edge 31 and the connecting edge 32 are at the intersection of the extreme ends, and the part of the connecting edge 32 is an extending end 33. As shown in fig. 1, two fixing holes 36 are formed in the flange 31, and the flange 31 fixes the pivot arm bracket 3 to the lower surface of the engine cover 6 by fixing members (such as bolts, etc., not shown) to the fixing holes 36. As shown in fig. 2, the inner side of the connecting edge 32 of the rotating arm bracket 3 is connected to the second end of the rotating arm 2 by the pin 26, and the connecting edge 32 of the rotating arm bracket 3 shown in fig. 3 further includes a movable groove 34, and the movable groove 34 is a through hole extending vertically. The rotating arm 2 is provided with a pin 25, and the pin 25 passes through the movable groove 34 and is connected to the outer side of the rotating arm 2, so that the pin 25 can move up and down along the movable groove 34.
With continued reference to fig. 1 and 2, the telescopic support 4 comprises a first end and a second end, the first end of the telescopic support 4 is movably connected to the extending end 33 of the rotating arm bracket 3, and the second end of the telescopic support 4 is movably connected to the second end 12 of the fixing base 1.
As a preferred embodiment of the present invention, as shown in fig. 3, the telescopic support 4 includes a gas spring 41, a first ball stud 42 and a second ball stud 43. Both ends of the gas spring 41 are connected to a first ball stud 42 and a second ball stud 43, respectively. The first ball stud 42 is riveted with the extending end 33 of the rotating arm bracket 3 as the first end of the telescopic support 4, and the second ball stud 43 is riveted with the second end 12 of the fixed seat 1 as the second end of the telescopic support 4. The telescopic support 4 adopts the gas spring 41, so that after a user manually opens and closes the engine cover for a certain height, the engine cover can be automatically opened and closed due to the expansion and contraction of the gas spring 41. It will be appreciated by those skilled in the art that the riveting manner is only one of many embodiments of the present invention, and in other embodiments of the present invention, the first ball stud 42 and the second ball stud 43 may be connected to the extending end 33 of the rotating arm bracket 3 and the second end 12 of the fixing base 1 respectively in other manners and may be movable with respect to each other.
With continued reference to fig. 1 and 2, the exciter 5 is disposed below the flange 31 of the rotating arm bracket 3, and upon receiving the collision signal, forms an upward thrust on the flange 31 of the rotating arm bracket 3. After the rotating arm support 3 receives upward thrust, the engine hood 6 is further lifted for a certain distance upwards, so that the function of protecting pedestrians is achieved.
As a preferred embodiment of the present invention, the vibration exciter 5 is a telescopic rod, and the vibration exciter 5 may be connected to the fixing base 1 by a fixing member (not shown in the drawings), or may be separately provided without being connected to the fixing base 1. As shown in fig. 4, when receiving the collision signal, one end 51 of the vibration exciter 5 extends upward and lifts the rotating arm bracket 3, especially the lower surface of the flange 31, so that the rotating arm bracket 3 drives the rear end of the engine cover 6 to lift upward by a certain height.
As an embodiment of the present invention, as shown in fig. 3 and 4, the position where the exciter 5 lifts the swing arm bracket 3 is located at the middle of the lower surface of the flange 31 or the other end away from the extending end 33. Preferably, the exciter 5 is lifted up at a position close to the position of the movable groove 34. Those skilled in the art can understand that the position where the vibration exciter 5 jacks the rotating arm support 3 is variable, the vibration exciter 5 can be arranged at a plurality of reasonable positions on the lower surface of the flange 31, and the positions can realize the effect of jacking the rotating arm support 3 by the vibration exciter 5.
In one embodiment of the present invention, the operation of the exciter 5 is triggered by the reception of an impact signal. When the vehicle is in normal use, the collision signal can not be sent out, so the vibration exciter 5 can not lift the rotating arm support 3 under normal conditions. When the vehicle is in collision, particularly when the collision position is located at the head of the vehicle, the corresponding sensor located at the head of the vehicle sends out a collision signal to indicate that the head of the vehicle is collided. Meanwhile, the vibration exciter 5 receives the collision signal from the sensor, and immediately and rapidly responds to the collision signal to lift the rotating arm support 3.
As can be seen from fig. 1-4, in the active hinge state, the fixing seat 1 is still in place because the fixing seat 1 is fixed on the cross beam of the car frame. At this time, the first end 21 of the rotating arm 2 rotates around the first end 11 of the fixing base 1, and the second end 22 of the rotating arm 2 is lifted upward and away from the second end 12 of the fixing base 1. Meanwhile, since the vibration exciter 5 jacks up the middle position or the rear position of the rotating arm support 3, the rotating arm support 3 rotates to a certain degree around the pin shaft 26 at the second end 22 of the rotating arm 2, so that the rotating arm support 3 is no longer clung to and depends on the rotating arm 2, i.e. the flanging 31 of the rotating arm support 3 shown in fig. 4 jacks up a certain distance along the supporting edge 23 of the rotating arm 2. As shown in fig. 3 and 4, the fixed base 1 and the rotating arm bracket 3 are maintained in a relatively approximately parallel position, and the rotating arm 2 as a component connecting the fixed base 1 and the rotating arm bracket 3 is in a tilted state.
As shown in fig. 3, the outer side of the connecting edge 32 of the pivot arm support 3 is further provided with a resilient hook 35, and the resilient hook 35 is capable of exerting a force on the pin 25 towards the flange 31 of the pivot arm support 3. Because round pin axle 25 is fixed on the swinging boom 2, resilience hook 35 applys a power towards swinging boom support 3's turn-ups 31 to round pin axle 25, is equivalent to making turn-ups 31 receive a power towards swinging boom 2 for round pin axle 25 remains the top at activity groove 34 throughout, can guarantee like this when not having vibration exciter 5 to exert external force, swinging boom support 3 can remain throughout hugging closely with swinging boom 2. On the other hand, when exciter 5 applies an upward force to flange 31, the force is greater than that of resilient hook 35, so that flange 31 moves upward and resilient hook 35 moves downward. As soon as the force of the exciter 5 is removed, the flange 31 moves towards the swivel arm 2 under the influence of the force of the resilient hook 35, eventually enabling the swivel arm carrier 3 to abut and rest on the swivel arm 2.
As one embodiment of the present invention, as can be seen from fig. 1, 2, 3 and 4, the rotating arm 2 is substantially S-shaped along the longitudinal direction, the first end 21 of the rotating arm 2, i.e., one end of the S-shape, is hinged to the first end 11 of the fixing base 1 and is closely attached thereto, and the second end 22 of the rotating arm 2, i.e., the other end of the S-shape, is separated from the fixing base 1 due to the S-shape, so that a certain distance is generated between the second end of the rotating arm 2 and the second end of the fixing base 1. Therefore, the rotating arm bracket 3 connected to the second end of the rotating arm 2 is also spaced from the fixing base 1. The telescopic support 4 is then arranged in this distance such that the telescopic support 4 is located in an intermediate position between the stationary base 1 and the rotary arm 2. As can be understood by those skilled in the art, the gas spring 41 is integrated at the middle position between the fixed seat 1 and the rotating arm 2, and a reinforcing plate is omitted from being installed on the gas spring 41, so that the weight of the whole active hinge can be reduced.
Therefore, no matter the active hinge is in a closed state, an active bounce state or an open state, the spatial positions of the fixed seat 1, the rotating arm 2, the rotating arm support 3, the telescopic support 4 and the vibration exciter 5 in the horizontal direction are sequentially the fixed seat 1, the telescopic support 4, the rotating arm support 3, the rotating arm 2 and the vibration exciter 5 respectively. Considering that the fixed seat 1 is fixed to a cross beam of a vehicle frame, when the active hinge is arranged inside an engine compartment of a vehicle, the sequence of the parts from the outside to the inside is the same.
As can be seen from fig. 1, 2 and 5, in the opened state of the active hinge, the fixing seat 1 is fixed on the cross beam of the car frame, so that the fixing seat 1 is still kept in place. At this time, the first end of the rotating arm 2 rotates around the first end of the fixing base 1, and the second end of the rotating arm 2 is lifted upwards and away from the second end of the fixing base 1. However, since there is no exciter 5 to lift rotary arm support 3 and the force exerted by telescopic support 4 on rotary arm support 3 is at its extended end 33, rotary arm support 3 is still in close contact and rests on rotary arm 2 and the distance of the second end of rotary arm 2, or extended end 33 of rotary arm support 3, from stationary base 1 is increasing until telescopic support 4 (gas spring 41) is at its maximum extended position.
In the open state, the telescopic support 4, or the gas spring 41, is extended, thereby providing an upward force to the extension end 33 of the rotating arm support 3, so that the rotating arm support 3 drives the rotating arm 2 to move upward, and the rotating arm 2 rotates relative to the first end of the fixed base 1. On the other hand, since the force provided by the telescopic support 4 is located at the extended end 33 of the swivel support arm, this force does not affect the resilient hook 35, thereby enabling the swivel arm support 3 to remain snug and resting on the swivel arm 2. As can be seen from fig. 5, in the extended state of the telescopic support 4, the swivel arm 2 is opened, so that the active hinge "opens", and the hood 6 is correspondingly opened.
Referring to fig. 6-11, the present invention further discloses an engine cover employing the active hinge of the present invention. The engine cover also has a closed state, an active bounce state and an open state corresponding to the closed state, the active bounce state and the open state of the active hinge. Fig. 6 and 7 show the closed state of the hood, fig. 8 and 9 show the actively sprung state of the hood, and fig. 10 and 11 show the open state of the hood.
Referring to fig. 6 and 7, the fixed base 1 of the active hinge is connected to the horizontal beam of the frame of the automobile engine from the horizontal direction, and is close to the position of the A column of the automobile. The rotating arm 2 is used for providing a support for the rotating arm bracket 3, and the flange 31 of the rotating arm bracket 3 is fixed on the lower surface of the engine hood 6 and is close to the A column of the automobile. As shown in fig. 6 and 7, when hood 6 is in the closed state, exciter 5 does not lift up swing arm bracket 3, and telescopic support member 4 is also in the closed state, and at this time, hood 6 is in the closed position abutting against the vehicle body, as shown in fig. 7.
With combined reference to fig. 1-4 and 6 and 7, the interior region of the mounting block 1 is located on the side of the mounting block 1 and is intended to be secured to a cross member of a vehicle frame, it being seen that the mounting block 1 is secured to the cross member of the vehicle frame from the side rather than being mounted to the upper surface of the vehicle frame. In this way, the entire active hinge can be arranged in the engine compartment below the hood 6 and at the rear of the engine compartment, i.e. close to the cab. Generally, since the rear part of the engine compartment generally has some space, the arrangement of the active hinge can increase the arrangement space of the engine hood and the front compartment.
For the above reasons, unlike the prior art, the above-described structure of the present invention, which does not require folding the telescopic support 4 within certain parts, can employ a larger-sized telescopic support 4 (or a larger-sized gas spring 41) instead of a smaller-sized gas spring as in many prior art. On the other hand, the structure of the active hinge does not need to adopt very compact arrangement, so that the active hinge has the advantages of simple structure, low manufacturing cost and more convenience and rapidness in processing, manufacturing and installation.
Referring to fig. 8 and 9, in the actively-raised state of the engine cover 6, the exciter 5 lifts the swing arm bracket 3 so that the engine cover 6 is raised accordingly. The front end of the engine hood 6 shown in fig. 8 and 9 is the end near the head, and the rear end is the end near the a-pillar of the automobile. As can be seen from fig. 8 and 9, since the rotating arm bracket 3 is fixed to the rear end of the hood 6 near the a-pillar of the vehicle, the rear end of the hood 6 is lifted upward in the actively sprung state, while the position of the front end remains substantially unchanged. Therefore, the actively sprung state of the hood 6 makes it take a posture of low front and high rear as shown in fig. 9.
When the vehicle bumps, because pedestrian's head has the risk of bumping with engine hood 6, the swinging boom support 3 of active hinge rises a take the altitude this moment for engine hood 6 also corresponding lifting takes the altitude certain, can increase collision buffer space when the vehicle bumps like this, reduces the collision injury value.
Referring to fig. 10 and 11, in the open state of the hood 6, the telescopic support 4 is in an extended state, and the telescopic support 4 provides an upward force to the extension end 33 of the swing arm bracket 3, so that the swing arm bracket 3 drives the swing arm 2 to move upward, thereby "opening" the active hinge. In this state, the front end of the hood 6 is tilted upward.
The hood 6 is a part that does or does not need to be opened during use of the vehicle. In the operation process, when the engine hood 6 is opened or closed to reach the balance point, the engine hood can be automatically opened to the maximum position or the complete closing state through the gas spring 41, so that the effect of saving power is achieved, and the user experience is improved.
One difference from the prior art is that in the active bounce state of the active hinge, the invention lifts the rotating arm bracket 3 upwards through the exciter 5, so that the rear end of the engine cover 6 is lifted upwards, and in this way, pedestrians are protected. In the process, the flange 31 is lifted upwards by the exciter 5, and the telescopic support 4 does not extend upwards, so that only the flange 31 moves upwards. It can be seen that in the active bounce state, the front end of the hood 6 is still in line with the position of the closed state, i.e., remains in the original position, while the rear end of the hood 6 is lifted upward, so that the hood 6 takes a low-front high-rear posture, which enables the hood 6 to better protect a pedestrian when colliding with the pedestrian.
On the other hand, the active bounce state is not to lift up the engine cover 6 by expanding the telescopic support 4, i.e., the gas spring 41, but instead the exciter 5 is used. Since the response speed of the exciter 5 can be significantly faster than that of a hydraulic component, a gas spring 41 or the like, the lifting of the flange 31 by using the exciter 5 can make the lifting speed of the engine cover 6 faster. This faster speed is more beneficial for pedestrian protection because in the event of a collision, the hood 6 must adjust its attitude faster if it is to function as a pedestrian protector, or else the pedestrian protection time window is lost.
Another difference from the prior art is that the active hinge of the invention and its hood 6 can be switched between a closed state, an active pop-up state, and an open state without the need for additional parts or additional maintenance. As can be seen from fig. 1-11, the active hinge and its hood 6 of the present invention, whether in the active pop-up or open position, can be returned to the initial closed position by simple depression without additional maintenance or configuration.
For example, when the active hinge is in the active bounce state shown in fig. 3 and 4, or when the engine cover 6 is in the active bounce state shown in fig. 8 and 9, the telescopic rod of the exciter 5 can be retracted and reset by pressing down the rotating arm bracket 3 or the rear end of the engine cover 6, so that the active hinge or the engine cover 6 can be restored to the closed state. On the other hand, when the active hinge is in the open state shown in fig. 5, or the hood 6 is in the open state shown in fig. 10 and 11, the telescopic support 4 can be retracted and restored by pressing down the front end of the rotating arm bracket 3 or the hood 6, so that the active hinge or the hood 6 can be restored to the closed state.
It can be seen that the active hinge and the hood thereof according to the present invention do not enter any state in a "destructive manner", in particular, do not enter an active bounce state in a "destructive manner", but are switched between states in a "non-destructive manner" by the specific structure of the active hinge as described above.
In summary, the active hinge and the engine hood using the same of the present invention have the following beneficial effects:
1. the injury value to the pedestrian can be reduced, and the pedestrian is effectively protected;
2. the structure is simple, and the manufacturing cost is low;
3. the arrangement space of the engine hood and the front cabin is enlarged;
4. the weight is light;
5. the man-machine interaction is good, and after the engine cover is manually opened and closed at a certain height, the engine cover can be automatically opened and closed.
It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above described embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
