Accompanying drawing explanation
Fig. 1 is the view that removes tailgate outside plate of the present utility model;
Fig. 2 is schematic side view of the present utility model;
In figure, 1: backdoor inner plate; 2: hinge stiffening plate; 3: gas strut brace panel; 4: rain shaving electrical machine brace panel; 5: door lock reinforcing plate; 6: tailgate outside plate; 11: glass port; 12: lightening hole.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following instance is used for illustrating the utility model, but is not used for limiting scope of the present utility model.
As illustrated in fig. 1 and 2, a kind of automotive back door of the utility model, comprise tailgate outside plate 6 and with the backdoor inner plate 1 of its laminating, this automotive back door also comprise be arranged between tailgate outside plate 6 and backdoor inner plate 1 and with the gentle strut brace panel 3 of hinge stiffening plate 2 of tailgate outside plate 6 and backdoor inner plate 1 overlap joint, hinge stiffening plate 2 and gas strut brace panel 3 adjacency.Preferably, the gentle strut brace panel 3 of hinge stiffening plate 2 is all two, and hinge stiffening plate 2 is arranged on the position, both sides of this automotive back door top edge; Gas strut brace panel 3 is arranged on this automotive back door left and right edges position.Preferably gas strut brace panel is arranged on the midway location of left and right edges.Hinge stiffening plate 2 extends to both sides respectively along automotive back door upper limb, at the corner location of automotive back door to downward-extension; Gas strut brace panel 3 boundary positioies along automotive back door both sides extend up and down.The gentle strut brace panel 3 of hinge stiffening plate 2 is corresponding respectively with the position of the gentle strut of hinge.When the top cover of automobile is subject to larger pressure, the energy that top cover is delivered to the lap position of backdoor inner plate 1 and tailgate outside plate 6 can decompose the inside and outside plate of tailgate, and by transmitting to whole back door with the gentle strut brace panel 3 of hinge stiffening plate 2 of backdoor inner plate 1 and tailgate outside plate 6 overlap joints, reduce the distortion at back door top, guarantee occupant's safety.Hinge stiffening plate 2 and gas strut brace panel 3 adjoining position places have along hinge stiffening plate 2 transmission power to backdoor inner plate 1 and tailgate outside plate 6, then from backdoor inner plate 1 and tailgate outside plate 6, pass to the longitudinal annular power transferring structure of gas strut brace panel 3.
Further, at the upper position of this automotive back door, be provided with glass port 11, the lower edge of glass port 11 is provided with rain shaving electrical machine brace panel 4, and rain shaving electrical machine brace panel 4 is connected with gas strut brace panel 3.Rain shaving electrical machine brace panel 4 is for supporting rain shaving electrical machine, and rain shaving electrical machine brace panel 3 is connected with the gas strut brace panel 3 that is positioned at its position, both sides respectively.By rain shaving electrical machine, force the setting of plate, hinge stiffening plate 2, gas strut brace panel 3 and rain shaving electrical machine brace panel 4 form an annular power transmission space around along glass port, the power of being transmitted by gas strut brace panel 3 can be divided into two with the connection location place of rain shaving electrical machine brace panel 4 at gas strut brace panel 3, and a part is still transmitted along backdoor inner plate and tailgate outside plate; Another part transmits to rain shaving electrical machine brace panel.The good stability of the force transferring structure power transmission of annular, and there is good sorption, back door is stressed comparatively even everywhere, reduces the distortion of back door.Although be provided with the back door of glass port, its topside remitted its fury, has guaranteed the increase of stability and the power transmission effect of power transmission by annular force transferring structure, improves the intensity on back door top, guarantees occupant's safety.
Further, at the midway location of the lower edge of this automotive back door, be also provided with door lock reinforcing plate 5, door lock reinforcing plate 5 is arranged in the public lap position of tailgate outside plate 6 and the bottom of backdoor inner plate 1; Door lock reinforcing plate 5 is connected with rain shaving electrical machine brace panel 4.Door lock reinforcing plate 5 extends upward, and it is connected with the middle part of rain shaving electrical machine brace panel.When vehicle jolts operation: door lock passes to backdoor inner plate 1 and tailgate outside plate 6 by door lock reinforcing plate 5 by sinking impulsive force, the annular simultaneously consisting of rain shaving electrical machine brace panel 4, gas strut brace panel 3, hinge stiffening plate 2 is transmitted power structure and is upwards transmitted lower pulling force, guaranteed that more power is delivered in loop configuration, by brace panel, provide back door to support more by force and energy absorbing, thereby guaranteed to reduce the trend that back door sinks.
Further, the bottom of backdoor inner plate 1 is provided with a plurality of lightening holes 12, and lightening hole 12 is divided into the both sides of door lock reinforcing plate 5.Preferably, lightening hole 12 is symmetrically distributed in rear door lock both sides along this automotive back door medium line.Preferably, lightening hole 12 is two.The annular element of the surrounding of lightening hole 12 forms the closed force transferring structure of annular, the stability that assurance power is transmitted equally.
When vehicle body rolls, tumbling force decomposes each ring, and each ring is a plurality of Path of Force Transfer by power at Node Decomposition, and power, when multipath transmits, fully absorbs energy, reduces back door distortion, protection occupant.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
