Description
Technical Field
The invention relates to the technical field of vehicle safety control, in particular to a three-point jacking type active hood lifting system and a control method thereof.
Background
Statistically, in a traffic accident, the number of dead pedestrians and drivers of two-wheeled vehicles accounts for nearly 50% of the total number of people, and most of the deaths of pedestrians and drivers of two-wheeled vehicles are caused by the impact of the head and the vehicle. At present, china also pays more and more attention to the protection of vehicles on pedestrians, and a series of policies are developed successively to promote automobile manufacturers to research on how to reduce the damage to pedestrians when the pedestrians collide with the vehicles one after another. Currently, there are two main strategies for pedestrian head protection: one is passive strategies such as optimizing the structure of the engine cover and optimizing the arrangement of hard points of the engine compartment; the other is an active strategy of jacking the engine cover 1 by a jacking mechanism to increase the head impact buffering space. The existing active engine cover mainly comprises the following two technical schemes:
first, when a vehicle impacts a pedestrian, the rear part of the hood is lifted, and the space between the hood and a hard point of the cabin is enlarged, so that the pedestrian is protected. The space behind the hood is increased more in the scheme, but the increased space in the front of the hood is smaller, and even the space in the front of the hood lock is reduced, so that pedestrians with lower heights cannot be protected.
And secondly, when the vehicle collides with the pedestrian, the front part and the rear part of the hood are lifted by jacking the periphery of the hood, so that the space between the hood and a hard point of the engine room is enlarged, and the pedestrian is protected. The proposal can increase the space of the whole hood area, but the technical defects of the proposal are as follows: 1. four lifters and four active hinges are needed, the structure is complex, and the cost is high; 2. the areas covered by the two active hinges at the front part have high rigidity due to the complex mechanical structure support, and have poor protection effect on the head collision of pedestrians; 3. the front jacking structure is a destructive disposable structure and cannot be recycled.

Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth to illustrate, but are not to be construed to limit the scope of the invention.
As shown in fig. 1 to 3, the present embodiment provides a three-point jacking type active hood lifting system, which is disposed below a hood 1 of a generator, and includes a first jacking mechanism 2, a second jacking mechanism 3, and a third jacking mechanism 4 that are disposed at three points, where the first jacking mechanism 2 is disposed in the middle of the front end of the hood 1, and the second jacking mechanism 3 and the third jacking mechanism 4 are symmetrically disposed on two sides of the rear end of the hood 1; the hood lock support 5 is arranged on the hood 1, the first jacking mechanism 2 is connected with the lower end of the hood lock support 5, the hood lock 6 is fixedly arranged on the hood lock support 5 through screws and used for tightly locking the hood lock 6 on the hood lock 6, and the hood lock support 5 is used for supporting the hood lock 6; still be equipped with slot hole 7 on the automobile body, the vertical setting in long limit in slot hole 7, aircraft bonnet lock support 5 locks in slot hole 7 through ordinary bolt 8, and aircraft bonnet lock support 5 accessible connecting piece and slot hole 7 are in vertical sliding fit for aircraft bonnet lock support 5 has vertical floating space.
First climbing mechanism 2, second climbing mechanism 3 and third climbing mechanism 4 are similar to isosceles triangle and set up in aircraft bonnet 1 below to the mode of three point jacking is with engine bonnet 1 whole jack-up, thereby realizes the effect that the rear end all lifts up before aircraft bonnet 1. When the vehicle collides with a pedestrian, the rear end of the hood 1 is jacked up by using the second jacking mechanisms 3 and the third jacking mechanisms 4 on the two sides so as to increase the space between the hood 1 and a hard point of a vehicle body; the front end of the hood 1 is supported by the first jacking mechanism 2 through a single point, and the hood 1 on two sides of the supporting point can be downwards collapsed to absorb energy generated by impact and protect pedestrians, so that the range of collision protection on the heads of the pedestrians is enlarged. Preferably, the first jack 2 is provided at a middle position of the front end of the hood 1 to balance a supporting force to the front end of the hood 1. After the front part of the hood 1 is jacked up, the hood lock 6 and the hood lock bracket 5 move synchronously with the hood 1, so that the hood lock 6 and the hood lock bracket 5 cannot be collapsed or damaged in the collision process, can be recycled, and saves the vehicle maintenance cost. The elongated hole 7 of the vehicle body provides a space for the hood lock bracket 5 to ascend, thereby providing a space for the first jack 2 to push the hood lock bracket 5 and the hood 1 to ascend.
On the basis of the above technical solution, the present embodiment can be further improved as follows.
In this embodiment, as shown in fig. 4 to 5, the schematic diagram of the front and rear jacking structures of the first jacking mechanism 2 includes a first jacking device 201 and an electromagnet 202 that are vertically arranged, the fixed end of the first jacking device 201 and the electromagnet 202 are respectively and fixedly mounted on the vehicle body, and the movable end of the first jacking device 201 is detachably connected with the bottom end of the hood lock bracket 5 (for example, by using a contact surface abutting mode). When the hood 1 is in a closed state, the electromagnet 202 is attracted to the bottom surface of the hood lock bracket 5, and the hood lock bracket 5 is prevented from moving upwards along the elongated hole 7. When the condition of lifting the hood 1 is met, the electromagnet 202 is powered off to release the hood lock bracket 5, the movable end of the first jacking device 201 extends out, and the hood lock bracket 5 is pushed to lift with the hood 1. The lifting action of the first lifter 201 is fast, and due to inertia, after the hood lock bracket 5 is lifted, the hood lock bracket 5 is allowed to leave the movable end of the first lifter 201, and the elongated hole 7 of the vehicle body limits the range of the lifting of the hood lock bracket 5 and thus the front end of the hood 1. Before and after the jacking action, the hood lock 6 is always in a locked state without unlocking, so that the hood lock 6 and the hood lock bracket 5 are prevented from being damaged in the collision process, the hood lock can be still repeatedly used after collision, and the vehicle maintenance cost after collision is saved.
In this embodiment, as shown in fig. 2 and a comparison diagram of the front and rear jacking states of the hood 1 of fig. 3, the second jacking mechanism 3 and the third jacking mechanism 4 are distributed on the left and right sides of the rear end of the hood 1. The second jacking mechanism 3 comprises a first active hinge 302 and a second jacking device 301, wherein one end of the first active hinge 302 is hinged with the hood 1, and the other end of the first active hinge 302 is hinged with the vehicle body, so that the hood 1 can rotate around the vehicle body along the first active hinge 302; the fixed end of the second jack 301 is connected with the vehicle body, and the movable end of the second jack 301 is matched with the bottom surface of the hood 1 (for example, two contact surfaces are abutted), so that the hood 1 can be jacked up when the movable end of the second jack 301 extends out. As the second jacking mechanism 3 and the third jacking mechanism 4 are symmetrically arranged, similarly, the third jacking mechanism 4 comprises a second driving hinge 402 and a third jacking device 401, one end of the second driving hinge 402 is hinged with the hood 1, and the other end of the second driving hinge 402 is hinged with the vehicle body, so that the hood 1 can rotate around the vehicle body along the second driving hinge 402; the fixed end of the third jacking device 401 is connected with the vehicle body, and the movable end of the third jacking device is matched with the bottom surface of the hood 1, so that the hood 1 can be jacked up. The first active hinge 302 and the second active hinge 402 assist each other, and the second lifter 301 and the third lifter 401 assist each other to lift the rear end of the hood 1. Similarly, the jacking actions of the second jack 301 and the third jack 401 are fast, and due to inertia, after the rear end of the hood 1 is jacked, the bottom surface of the hood 1 is allowed to leave the movable ends of the second jack 301 and the third jack 401, and the range of the rear end of the hood 1 rising is limited by the strokes of the first active hinge 302 and the second active hinge 402.
In this embodiment, the first jack 201, the second jack 301, and/or the third jack 401 may be an electric jack, a hydraulic jack, or a pneumatic jack. The first jack 201, the second jack 301 and the third jack 401 can adopt various types of telescopic cylinders, and in order to ensure that the reaction speeds of the three jacks are close, the three jacks preferably use the same type of telescopic cylinder.
In this embodiment, since the vehicle-pedestrian impact usually occurs in a moment, the sensitivity of the vehicle reaction greatly affects the degree of injury to the pedestrian. In order to obtain higher reaction speed, all three lifters adopt a pyrotechnic lifter in a pneumatic lifter. Specifically, the pyrotechnic jack comprises a cylinder sleeve and a push rod which are coaxially sleeved, one end of the cylinder sleeve is sealed, the other end of the cylinder sleeve can be sealed in a sliding mode through the push rod, the push rod can slide along the axial direction of the cylinder sleeve, the cylinder sleeve and an outer shell of the cylinder sleeve are connected with a vehicle body as the fixed end of the pneumatic jack, and one end, extending out of the cylinder sleeve, of the push rod is connected with the hood 1 or the hood lock support 5 as the movable end of the pneumatic jack. The fuel, the combustion improver and the igniter are arranged in the cylinder sleeve and used for driving the pyrotechnic jack, the igniter is in communication connection with the vehicle controller, after the vehicle controller sends out a control signal for lifting the hood 1, the igniter ignites and explodes the fuel and the combustion improver in the cylinder sleeve, a closed combustion chamber is formed between the inner wall of the cylinder sleeve and the push rod, and high-pressure gas generated in the explosion moment pushes the push rod to slide along the inner wall of the cylinder sleeve, so that the hood 1 is jacked up. Because the explosion occurs in a short time, a large amount of high-pressure gas can be generated in a short time to push the push rod out, so that the jacking device can obtain a high reaction speed.
Based on the three-point jacking type active hood lifting system, the embodiment further provides a control method to realize control over the system, as shown in the control logic relationship diagram of fig. 6, the control method includes the following steps:
presetting a collision intensity threshold value in a vehicle controller, detecting a collision signal of the front end of the vehicle and comparing the collision signal with the collision intensity threshold value;
when the value of the collision signal is smaller than the collision strength threshold value, the vehicle controller outputs a first control signal to the electromagnet 202, the electromagnet 202 attracts and locks the hood lock bracket 5 according to the first control signal, and at the moment, the whole hood 1 is in a locked state;
when the value of the collision signal is greater than or equal to the collision strength threshold value, the vehicle controller outputs a second control signal to the electromagnet 202 and outputs a third control signal to the three lifters, the electromagnet 202 is powered off according to the second control signal and releases the hood lock bracket 5, and at the moment, the hood lock bracket 5 can vertically move along the elongated hole 7 of the vehicle body; the first jacking mechanism 2, the second jacking mechanism 3 and the third jacking mechanism 4 respectively extend out of respective movable ends according to a third control signal, at the moment, the hood lock support 5 rises along the long edge of the elongated hole 7, and the hood 1 is lifted to a set position under the action of the first active hinge 302 and the second active hinge 402, so that the purpose of jacking the whole hood 1 is achieved.
The working principle is as follows:
compared with the active hood 1 system which lifts up only from the rear part of the engine hood 1, the three-point jacking type active hood lifting system enables the engine hood 1 to lift up integrally, the buffer space in the front part of the engine hood 1 is enlarged, the head of a pedestrian with a lower height can be protected, and the protection range is wider; compared with the existing four-point support active hood 1 system, the technical scheme of the invention adopts the common hood lock 6, and has simple structure and low cost; in addition, because the front part of the hood 1 adopts a single-point supporting mode, when the hood 1 is collided, both sides of a supporting point can collapse downwards to absorb energy, and the collision protection range of the head of a pedestrian is wider; and finally, after the front part of the hood 1 is jacked up, the hood lock 6 and the bracket thereof cannot be collapsed or damaged, the hood lock can be repeatedly recycled, and the vehicle maintenance cost is saved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
