Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a hood lifting connection assembly and a vehicle. Background Art

[0002] At present, in the design of some vehicles, when the vehicle collides with a pedestrian during driving, the hood will pop up to buffer the head or other parts of the pedestrian's body, so as to reduce the harm to the pedestrian.

[0003] However, although this method can significantly reduce the injury of the pedestrian's head, there are many main problems in actual use. For example, when colliding with some small animals, basketballs, roadblocks, pillars and other targets during driving, the hood is also easily triggered to open, causing a large number of complaints from consumers that it does not really play a role in protecting pedestrians. Moreover, the hinge-type matching structure in the prior art is irreversible after the hood is accidentally opened and difficult to reset. Once the hood pops up, maintenance costs will be generated, resulting in waste of resources. Summary of the Utility Model

Detailed implementation manners

[0026] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals indicate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0027] Below, refer to Figures 1 - 4 Describe the engine hood lifting connection assembly 100 according to an embodiment of the present utility model. Through the cooperation of the first lifter 1 and the second lifter 2 with the engine hood 4 and the vehicle body, after the engine hood 4 pops up when the vehicle encounters a situation, it can be reset, saving the maintenance cost of the engine hood 4 popping up; in addition, when it is necessary to open the engine hood 4 from the front, the lifting amplitude of the engine hood 4 driven by the first lifter 1 can be controlled to be greater than the degree of the engine hood 4 lifted by the second lifter 2, so that the engine hood 4 rotates clockwise, thereby opening the engine hood 4 to perform maintenance and other operations on the various structures in the engine compartment. That is, by setting the first lifter 1 and the second lifter 2, the engine hood 4 can be opened forward and backward.

[0028] As Figures 1 - 4 shown, the engine hood lifting connection assembly 100 according to an embodiment of the present utility model includes: a first lifter 1, a second lifter 2 and a control module.

[0029] Among them, one end of the first jack 1 is movably connected to the vehicle body and the other end is movably connected to the hood 4; the second jack 2 is located behind the first jack 1 along the vehicle, and one end of the second jack 2 is fixedly connected to the vehicle body and the other end is movably connected to the hood 4; the control module is electrically connected to the first jack 1 and the second jack 2, and controls the operation of the first jack 1 and the second jack 2 according to the collision signal.

[0030] In practice, the first jack 1 and the second jack 2 can be driven by a motor, or can be driven by a cylinder or an oil cylinder, etc. The first jack 1 and the second jack 2 are both located at the bottom of the rear end of the hood 4 along the vehicle, and both the first jack 1 and the second jack 2 are connected to the vehicle body. At the same time, the first jack 1 is located on the front side of the second jack 2; in addition, the control module is a controller for controlling the first jack 1 and the second jack 2 to rise or reset. The vehicle has an active sensor. When the active sensor of the vehicle recognizes the calibrated collision signal, this signal is transmitted to the controller electrically connected to the first jack 1 and the second jack 2 on both sides in the engine compartment. The controller controls the first jack 1 and the second jack 2 to rise simultaneously, and the rear end of the hood 4 needs to be higher than the front end, so that the rear end of the hood 4 rises to buffer the head and other parts of the body of the collided pedestrian.

[0031] Furthermore, the first jack 1 is located on the front side of the second jack 2, and the amplitude of the second jack 2 driving the hood 4 to rise is greater than the amplitude of the first jack 1 driving the hood 4 to rise, so that the height of the rear side of the hood 4 is greater than the height of the front side; and the lower end of the first jack 1 is movably connected to the vehicle body and the upper end is movably connected to the hood 4. At the same time, the lower end of the second jack 2 is fixedly connected to the vehicle body and the upper end is movably connected to the hood 4. Then when the first jack 1 and the second jack 2 both rise, due to the movable connection between the first jack 1 and the vehicle body, that is, the movable connection between the first jack 1 and the vehicle body can release the degree of freedom, the first jack 1 and the second jack 2 can both rise smoothly and flexibly, and the cooperation between the first jack 1 and the second jack 2 is better. Moreover, the cooperation between the first jack 1 and the second jack 2 can improve the stability when the hood 4 rises or resets, so that the hood 4 has a relatively stable support.

[0032] In addition, after the first jack 1 and the second jack 2 lift the hood 4 and it is found to be a misoperation, or when the vehicle does not collide with a pedestrian, the control module can be used to control the first jack 1 and the second jack 2 to reset simultaneously, that is, the hood 4 can be reset more conveniently at this time, solving the problem of the need for maintenance costs when the hood 4 rises at the rear end in the prior art.

[0033] Moreover, when it is necessary to open the hood 4 from the front, the lifting amplitude of the hood 4 driven by the first lifter 1 can be controlled to be greater than that driven by the second lifter 2, so that the hood 4 rotates clockwise, thereby opening the hood 4 for maintenance operations on various structures in the engine compartment. That is, through the settings of the first lifter 1 and the second lifter 2, the hood 4 can be opened both forward and backward, and the operation is more convenient. Forward means the front side of the hood 4 rises, and backward means the rear side of the hood 4 rises.

[0034] Thus, for the hood lifting and connecting assembly 100 of the embodiment of the present utility model, after the hood 4 pops up, the operation is reversible, saving the maintenance cost of the hood 4 popping up.

[0035] In some embodiments, the first lifter 1 includes a first piston rod 11 and a first housing 12. The first piston rod 11 is movably connected to the hood 4, and the first housing 12 is movably connected to the vehicle body. The second lifter 2 includes a second piston rod 21 and a second housing 22. The second housing 22 is fixedly connected to the vehicle, and the second piston rod 21 is movably connected to the hood 4.

[0036] In practice, the first piston rod 11 and the hood 4 can be rotatably connected through a rotating shaft, and the first housing 12 and the vehicle body are movably connected through another rotating shaft. Similarly, the second piston rod 21 and the hood 4 are rotatably connected through another rotating shaft, and the second housing 22 is fixedly connected to the vehicle body through a connecting member.

[0037] That is Figure 1 when the second piston rod 21 of the second lifter 2 rises, due to the rotational connection between the second piston rod 21 and the hood 4, and the fixed connection between the second housing 22 and the vehicle body, no rotation will occur except for the axial movement of the second piston rod 21. At this time, the hood 4 can rotate counterclockwise relative to the second piston rod 21. At the same time, due to the support of the first lifter 1 for the hood 4, the first lifter 1 is movably connected to the vehicle body and the hood 4. When the first lifter 1 rises, in addition to the axial movement of the first piston rod 11, the first lifter 1 can slightly rotate to better cooperate with the second lifter 2 and lift the hood 4. As Figure 1 shown, after the first lifter 1 and the second lifter 2 lift the hood 4, the changing state of the hood 4 is as Figure 2 shown. At this time, the first lifter 1 can rotate clockwise along Figure 1 about 5 - 7° to lift the hood 4 more smoothly.

[0038] In some embodiments, there is an included angle between the extension lines of the first lifter 1 and the second lifter 2, and the distance between the first lifter 1 and the second lifter 2 near the vehicle body end is greater than the distance between them near the hood 4 end.

[0039] In practice, by setting an angle between the first jack 1 and the second jack 2, that is, when the hood 4 is in a closed state, a trapezoidal structure is formed between the first jack 1, the second jack 2, the hood 4 and the vehicle body, so that the first jack 1 and the second jack 2 can better and more stably support the hood 4.

[0040] Moreover, when the second lifter 2 and the first lifter 1 need to cooperate to lift the hood 4 to a certain extent, the first piston rod 11 of the first lifter 1 and the second piston rod 21 of the second lifter 2 do not move a large range, and a small range of axial movement can be achieved to lift the hood 4 to the required angle.

[0041] In some embodiments, a first driving member 7 is provided on the side of the first jacking device 1 facing away from the second jacking device 2, and the output shaft of the first driving member 7 is parallel to the first piston rod 11 and is connected to the transmission through a power assembly; a second driving member 9 is provided on the side of the second jacking device 2 facing away from the first jacking device 1, and the output shaft of the second driving member 9 is parallel to the second piston rod 21 and is connected to the transmission through another power assembly.

[0042] In practice, the first driving member 7 can be arranged on the front side of the first jacking device 1, and the second driving member 9 can be arranged on the rear side of the second jacking device 2, that is, the first driving member 7 and the second driving member 9 are avoided from being arranged between the first jacking device 1 and the second jacking device 2, thereby avoiding affecting the operation of the first jacking device 1 and the second jacking device 2, and the output shaft of the first driving member 7 is parallel to the first piston rod 11, and the output shaft of the second driving member 9 is parallel to the second piston rod 21, which saves the space in the height direction between the vehicle body and the hood 4, and at the same time can realize the jacking operation of the first driving member 7 on the first jacking device 1 and the jacking operation of the second driving member 9 on the second jacking device 2.

[0043] Among them, combined Figure 4As shown in the figure, the power assembly includes the motor drive shaft 71 of the first drive member 7, the driving wheel 72, the power transmission belt 73, the driven wheel 112 and the lead screw 111. The lead screw 111 and the driven wheel 112 are fixedly connected, and the driven wheel 112 can rotate relative to the first housing 12. The motor drive shaft 71 is the output shaft of the first drive member 7. When the motor drive shaft 71 drives the driving wheel 72 to rotate, it can drive the power transmission belt 73 to move. The movement of the power transmission belt 73 drives the driven wheel 112 to rotate relative to the first housing 12, and the driven wheel 112 is fixedly connected to the lead screw 111, that is, the power transmission belt 73 drives the lead screw 111 to rotate. The first piston rod 11 is sleeved on the lead screw 111 and is in threaded cooperation with the lead screw 111. By designing the lead screw 111 to rotate relative to the first housing 12 but not axially moveable, that is, the first housing 12 can rotatably support the lead screw 111. When the lead screw 111 rotates, it can drive the first piston rod 11 to extend and retract to realize the operation of the first jack 1.

[0044] Similarly, the operation of the second jack 2 can also adopt the same power assembly as the first jack 1. Through this power assembly, the power transmission between the parallel first piston rod 11 and the output shaft of the first drive member 7 can be realized, and the power transmission between the parallel second piston rod 21 and the output shaft of the second drive member 9 can also be realized. The overall layout is reasonable and space is saved.

[0045] In some embodiments, there is a common installation space 10 between the first drive member 7 and the first housing 12, and there is another common installation space 10 between the second drive member 9 and the second housing 22. At least part of the power assembly is arranged in the common installation space 10.

[0046] In practice, that is, there is a common installation space 10 between the first drive member 7 and the first housing 12. The driving wheel 72, the driven wheel 112 and the power transmission belt 73 can be arranged in the installation space 10 to realize the power transmission between the first drive member 7 and the first piston rod 11 when the first drive member 7 and the first piston rod 11 are arranged in parallel, saving space. At the same time, the housing corresponding to the common installation space 10 is the common housing, which also improves the integration degree of the first drive member 7 and the first housing 12.

[0047] In addition, the structural setting between the second jack 2 and the second drive member 9 is arranged in the same way as that between the first drive member 7 and the first housing 12.

[0048] In some embodiments, the included angle between the axial centerline of the first piston rod 11 of the first jack 1 and the vertical direction is greater than the included angle between the axial centerline of the second piston rod 21 of the second jack 2 and the vertical direction.

[0049] In practice, the vertical direction is the directly above and directly below directions of the vehicle, such as Figure 1As shown, the included angle between the axial center line of the first piston rod 11 of the first jack 1 and the vertical direction is a, and the included angle between the axial center line of the second piston rod 21 of the second jack 2 and the vertical direction is b, and it satisfies: a > b.

[0050] Furthermore, when the included angle a between the first piston rod 11 of the first jack 1 and the vertical direction is relatively large, at this time, the first jack 1 is more inclined. When the hood 4 needs to be raised to the final required height, then the length that the first piston rod 11 of the first jack 1 can extend is shorter; since when the vehicle hits a pedestrian, the rear end of the hood 4 only rises slightly, while when the hood 4 needs to be opened from the front of the vehicle, the opening amplitude of the hood 4 from the front is larger. Then when the first jack 1 and the second jack 2 drive the rear end of the hood 4 to rise, the first piston rod 11 of the first jack 1 can achieve the rise by extending a shorter length. And when the front of the hood 4 needs to rise and the rear end is lower than the front, that is Figure 3 in the state shown in [description], at this time, the first piston rod 11 needs to extend longer. By setting the included angle between the first piston rod 11 of the first jack 1 and the vertical direction to be larger, the length of the extension of the first piston rod 11 can be reduced, saving space, and enabling the hood 4 to quickly rise to the final required angle.

[0051] In some embodiments, the hood lifting connection assembly 100 further includes a hood mounting ear 3, a first jack mounting ear 5, and a second jack mounting ear 6. The hood mounting ear 3 is formed with a hood mounting groove 31 that opens away from the hood 4. The ends of the first jack 1 and the second jack 2 close to the hood 4 are rotatably mounted in the hood mounting groove 31. The first jack mounting ear 5 and the second jack mounting ear 6 are both provided with a vehicle body mounting groove 51 facing the hood 4. The end of the first jack 1 is rotatably connected in the corresponding vehicle body mounting groove 51, and the end of the second jack 2 is fixedly connected in the corresponding vehicle body mounting groove 51.

[0052] First of all, the distance between the ends of the first jack 1 and the second jack 2 connecting the hood 4 is shorter. Through one hood mounting ear 3, the rotational connection between the first jack 1 and the second jack 2 and the end of the hood 4 can be realized, saving the number of hood mounting ears 3 used. And after one hood mounting ear 3 is connected to the hood 4, the connection strength between the first jack 1, the second jack 2 and the hood 4 respectively can be enhanced, making the connection positions of the first jack 1 and the second jack 2 with the hood 4 more concentrated. Thus, when the first piston rod 11 and the second piston rod 21 extend, the acting force can be more concentratedly transmitted to the rear end of the hood 4, so that the rear end of the hood 4 can rise quickly.

[0053] That is, by providing the hood mounting groove 31, it is convenient to rotatably connect the first lifter 1 and the hood mounting ear 3 through a rotating shaft. The rotating shaft is fixedly connected to the hood mounting ear 3, and the hood mounting ear 3 is fixedly connected to the hood 4. At the same time, it is also convenient to rotatably connect the second lifter 2 and the hood mounting ear 3 through another rotating shaft. The rotating shafts corresponding to the first lifter 1 and the second lifter 2 can be hidden in the hood mounting groove 31. The space in the hood mounting groove 31 can also provide space for the hood 4 to rotate relative to the first lifter 1 and the second lifter 2.

[0054] The other end of the first lifter 1 is connected to the vehicle body through the first lifter mounting ear 5. A connecting block 121 can be provided at the bottom of the first housing 12 of the first lifter 1. The connecting block 121 is rotatably connected to the vehicle body mounting groove 51 through a rotating shaft. The other end of the second lifter 2 is connected to the vehicle body through the second lifter mounting ear 6. For example, a connecting block 121 is also provided at the bottom of the second housing 22. The connecting block 121 is fixedly connected to the vehicle body through a connecting member. By separately arranging the first lifter mounting ear 5 and the second lifter mounting ear 6, the material of the mounting ear can be saved, and the strength of the connection between the first lifter 1 and the vehicle body and the strength of the connection between the second lifter 2 and the vehicle body can be improved respectively.

[0055] In some embodiments, the end of the first lifter 1 is rotatably connected to the first lifter mounting ear 5 on the side close to the second lifter 2.

[0056] That is, referring to Figure 2 As shown, the right side of the connecting block 121 and the first lifter mounting ear 5 are rotatably connected through a rotating shaft. Then when the first lifter 1 lifts the hood 4, the first lifter 1 will rotate clockwise around the connection position of the rotating shaft between the first lifter 1 and the first lifter mounting ear 5 during the cooperation with the second lifter 2, thus facilitating the rotation of the first lifter 1 and providing a rotating space for the rotation of the first lifter 1. And since the second lifter 2 is located behind the first lifter 1, setting the connection between the first lifter 1 and the vehicle body on the side close to the second lifter 2 can improve the cooperation effect between the first lifter 1 and the second lifter 2 while satisfying the rotation.

[0057] In some embodiments, the hood lifting connection assembly 100 further includes a vehicle body plate 8. The vehicle body plate 8 is connected to the vehicle body. The vehicle body plate 8 includes a first section 81 and a second section 82 extending along the front-rear direction of the vehicle. The end of the second section 82 away from the first section 81 is higher than the height of the first section 81. The first lifter 1 is rotatably connected to the first section 81 and rotatably connected to the hood 4. The second lifter 2 is fixedly connected to the second section 82 and rotatably connected to the hood 4.

[0058] In practice, the structural setting of the vehicle body panel 8 can cooperate with the position setting of the first jacking device 1 and the second jacking device 2 to facilitate the connection of the first jacking device 1 and the second jacking device 2. At the same time, the transition arc surface 83 can be set between the first section 81 and the second section 82 of the vehicle body panel 8 to prevent the first jacking device 1 and the second jacking device 2 from being subjected to force on the vehicle body respectively, which causes the first section 81 and the second section 82 of the vehicle body panel 8 to be deformed due to concentrated force.

[0059] In addition, the end of the second section 82 away from the first section 81 is higher than the height of the first section 81. Since the first section 81 is used to connect the first jacking device 1, and the first jacking device 1 and the second jacking device 2 are more inclined relative to the vertical direction, when the first jacking device 1 and the second jacking device 2 are provided with the same specifications, the position where the second jacking device 2 is connected to the vehicle body can be provided higher, that is, the position of the second section 82 is higher than that of the first section 81.

[0060] Moreover, the first section 81 is provided with a first connecting hole, and a bolt is passed through the first jacking mounting ear 5 and the first connecting hole to connect to the vehicle body. The second section 82 is provided with a second connecting hole, and a bolt is passed through the second jacking mounting ear 6 and the second connecting hole to connect to the vehicle body. If the first connecting hole is set at at least two locations and the second connecting hole is set at at least two locations, the connection strength between the first jacking mounting ear 5 and the second jacking mounting ear 6 and the vehicle body is improved.

[0061] It should be noted that when the vehicle needs to open the hood 4 forward, the driver can control the hood 4 to open at the first level in the vehicle. The first level opening is the initial opening of the hood 4, and the second level opening is the state where the hood 4 is fully opened. After the signal is judged and processed, a command is sent to drive the first jacking device 1 and the second jacking device 2 to work. The first jacking device 1 and the second jacking device 2 start to lift at a low speed at the same time. Then the driver needs to go to the front of the vehicle hood 4 to trigger the opening switch of the hood 4, and the hood 4 officially performs the forward opening action. The movement direction is shown in FIG. Figure 3 The hood 4 is lifted up at the hood mounting ear 3, and the hood 4 rotates clockwise around the rotation axis of the first lifter 1 and the hood mounting ear 3, and the other rotation axis of the second lifter 2 and the hood mounting ear 3, so that the hood mounting ear 3 drives the hood 4 to move upward. By controlling the first-level opening of the hood 4 in the vehicle and triggering the opening switch of the hood 4 outside the vehicle for the second-level opening, the opening of the hood 4 due to misoperation can be prevented.
