Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master.
In the present embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right side", "left end", "above", "back", "middle", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description of the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In addition, in the present embodiment, if the connection or fixing manner between the components is not specifically described, the connection or fixing manner may be a bolt fixing manner, a pin fixing manner, a welding fixing manner, or a hollow rotating shaft connection manner, which is commonly used in the prior art, and therefore, the detailed description thereof is omitted in this embodiment.
As shown in fig. 1-2, the present embodiment provides an electric lifting rod, which includes a connecting seat 1, a first connecting rod 2, a second connecting rod 3 and a driving device 4, the driving device in the present embodiment is a reduction motor, the reduction motor mainly includes a gear box and a motor, and the motor and the gear box are mutually matched to reduce the output rotation speed and simultaneously improve the output torque, so as to avoid the over-large load and the burnout when the motor is directly used for driving. The one end of first connecting rod 2 forms to rotate through the round pin axle with connecting seat 1 and is connected, the other end forms to rotate through the round pin axle with the one end of second connecting rod 3 and is connected, the length of first connecting rod 2 is greater than the length of second connecting rod 3, the other end and the drive arrangement 4 transmission of second connecting rod 3 are connected, connecting seat 1 passes through the bolt fastening with tail-gate 6, drive arrangement 4 drive second connecting rod 3 through the bolt fastening in automobile body 5 carries out clockwise or anticlockwise rotation and drives first connecting rod 2 and open or close tail-gate 6, realize that the automation of car tail-gate 6 opens or closes just promptly, thereby the convenience of car when using has been improved. Secondly, need not demolish to the gas vaulting pole 7 of former car, the gas vaulting pole 7 of lifting lever and former car can use mutually in coordination promptly, and the lifting lever only provides the power of opening the door and closing the door at the in-process that opens the door and close the door during use, and the gravity of automobile body 5 tail-gate 6 still is supported by the gas vaulting pole 7 of former car after the door is opened, and the lifting lever atress not this moment, consequently work is more reliable and more stable, and is also less relatively to drive arrangement 4's power requirement. When the air stay bar 7 of the original vehicle is damaged, the lifting bar can directly drive the air stay bar.
As shown in figures 3-4, when the lifting rod works, a stress point G is opposite to 2 rotating radiuses GB and GD, the whole process of GB is unchanged, GD is partially opened and is lengthened from short to long when the tail gate 6 is opened, and is closed and is shortened from long to short. Because the first connecting rod 2 and the second connecting rod 3 are in rotating connection, the problem of radius change in the rotating process is solved. Simultaneously for solving the problem that the radius of rotation changes more stably with the flexible mode of gas vaulting pole 7, the stroke that can change is bigger than the mode of stretching out and drawing back moreover.
As shown in fig. 1-2, in the preferred embodiment, the length ratio of the second link 3 to the first link 2 is 1: 1.6-2.0. the included angle of the first connecting rod 2 and the second connecting rod 3 is an acute angle when the vehicle tail door 6 is in a closed state, and the included angle of the first connecting rod 2 and the second connecting rod 3 is an obtuse angle when the vehicle tail door 6 is in an open state. The acute angle is 50-70 degrees, and the obtuse angle is 120-140 degrees. When the vehicle is designed for different models of vehicles, such as the height of the vehicle body 5 and the inconsistent inclination angle of the tail gate 6, the length ratio of the second connecting rod 3 to the first connecting rod 2 needs to be adjusted, for example, 1: 1.8, so that the lifting rod can drive the vehicle door to be closed smoothly; meanwhile, when the tail gate 6 is used for different vehicle types, the included angle can be flexibly adjusted when the tail gate is opened or closed, such as 60 degrees and 130 degrees.
As shown in fig. 1-2, an automobile comprises an automobile body 5, a tail gate 6 and/or an air supporting rod 7, wherein the tail gate 6 is rotatably connected with the automobile body 5 through a pin shaft, one end of the air supporting rod 7 is rotatably connected with the automobile body 5 through a pin shaft, the other end of the air supporting rod is rotatably connected with the tail gate 6 through a pin shaft, the automobile further comprises an electric lifting rod, one end of the electric lifting rod is fixed with an automobile door through a bolt, and the other end of the electric lifting rod is fixed with the tail gate 6 through a bolt.
The technical effects of the utility model mainly embody in following aspect: the automatic opening or semi-closing of the automobile tail door can be realized by additionally arranging the electric lifting rod, so that the convenience of the automobile is improved; secondly, the gas vaulting pole to former car can not need to be demolishd, and the gas vaulting pole of lifting lever and former car can use in coordination each other promptly, and the lifting lever is only opening the door and the power of closing the door that provides the door with the in-process of closing the door during use, and the gravity of automobile body tail-gate still is supported by the gas vaulting pole of former car after the door is opened, and the lifting lever is not atress this moment, consequently works more stably and reliably, and power requirement to drive arrangement is also less relatively.
Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
