Description
Technical field
The present invention relates to automotive body structure design fields, and in particular to a kind of installation knot of the electronic strut of back door
Structure.
Background technique
Back door is component important on body of a motor car, when being packed into boot and taking out article, is required by rear
The switch of tailgate realizes that in routine vehicle use process the frequency of usage of back door is very high.As consumer is to vapour
The raising that vehicle usage experience requires, traditional mechanical, hand-driven back door can not meet consumer demand gradually, in order to suitable
The demand in market is answered, electronic back door has become the development trend of mainstream.Electronic back door relative to tradition machinery it is manual after
Stress condition is more for tailgate, and the electronic strut that support back door is opened is opening moment or some other operating condition lower stress
Can be very big, this can the stiffness and strength at the installation point to electronic strut there is very big test.Therefore electronic strut is improved
Installation point stiffness and strength are to be highly desirable, if stiffness and strength are insufficient, be will lead in the case where being commonly used, generate compared with
Big deformation seriously affects the use of electronic back door.
Summary of the invention
The object of the present invention is to provide a kind of electronic struts of back door that can satisfy rigidity and strength character requirement
Mounting structure.
To achieve the goals above, the technical solution adopted by the present invention are as follows: a kind of mounting structure of the electronic strut of back door,
Including back door inner panel, one end of electronic strut is fixed by plate face installation on the inside of mounting plate and back door inner panel, in back door
Stiffening plate, mounting plate and the welding surface of back door inner panel and the weldering of stiffening plate and back door inner panel are welded in the outside plate face of plate
Junction is the two sides plate face of plate body near back door inner panel the same area respectively.
In above scheme, the other side of the welding surface of mounting plate and back door inner panel is arranged in stiffening plate, that is to say, that
Stiffening plate, mounting plate, back door inner plate welding be an entirety, not only solve electronic strut installation point part rigidity, by force
Degree problem also strengthens the structure of back door inner panel itself, improves the mode of back door entirety.
Detailed description of the invention
Fig. 1 is explosive view of the invention；
Fig. 2 is the welding schematic diagram of stiffening plate and back door inner panel；
Fig. 3 is the structural schematic diagram of upper reinforcing plate；
Fig. 4 is the structural schematic diagram of lower reinforcing plate.
Specific embodiment
For ease of description with facilitate understand, illustrate and define several basic directions and position concept first.Inside is
Close to the side in compartment, outside is the side far from compartment.
As Figure 1-Figure 4, the mounting structure of the electronic strut of a kind of back door, including back door inner panel 10, electronic strut
20 one end is fixed by mounting plate 30 and the installation of 10 inside plate face of back door inner panel, is welded in the outside plate face of back door inner panel 10
It is connected to stiffening plate 40, the mounting surface and stiffening plate 40 of mounting plate 30 and back door inner panel 10 and the welding surface point of back door inner panel 10
It is not the two sides plate face of plate body near 10 the same area of back door inner panel.Stiffening plate 40 is arranged in mounting plate 30 and back door inner panel
The other side of 10 mounting surface, that is to say, that stiffening plate 40, mounting plate 30, back door inner panel 10 are welded as a whole, no
Rigidity, the strength problem for addressing only electronic 20 installation point of strut part, also strengthen the structure of back door inner panel 10 itself, mention
The mode of high back door entirety, the problems such as preventing back door generation abnormal sound, shake, deform.
Preferably, the stiffening plate 40 includes upper reinforcing plate 41, the welding surface face of upper reinforcing plate 41 and mounting plate 30
It is arranged and the welding region of upper reinforcing plate 41 and back door inner panel 10 is greater than the installation region of mounting plate 30 and back door inner panel 10,
Upper reinforcing plate 41 is the multistage bending plate being bonded with back door inner panel 10, and the periphery of bending plate is provided with away from back door inner panel 10
Solder joint is arranged with 10 joint place of back door inner panel in first flange 411 of direction fold, the first flange 411.The upper of multistage bending adds
The orderly binding face of Design hierarchy, is connected together these binding faces with back door inner panel 10 by solder joint on strong plate 41, is welded
Point is rationally distributed by optimizing, and increases the transmission path of power, is conducive to disperse local stress, improves the local strength of installation point,
Prevent metal plate and solder joint from cracking.
Setting is there are two mounting hole 412 in the plate face corresponding with mounting plate 30 of upper reinforcing plate 41, upper reinforcing plate 41 up and down
First positioning hole 413 is offered in the plate face at both ends, prevents appearance position deviation in assembling process；Two first positioning holes 413 it
Between plate body on be provided with the first lightening hole 417 and achieve the purpose that loss of weight, so that it is met rigidity, strong under the premise of weight is most light
Degree requires, and buckle avoid holes 414 are offered on the first flange 411 of the left and right sides of upper reinforcing plate 41.The above hole is all
Rigidity, the lesser position of intensity effect are opened up on upper reinforcing plate 41.
In order to improve the local stiffness of installation point position, it is provided in the plate face of 412 region of mounting hole lateral and perpendicular
To the strengthening rib strip 415 of arrangement, while these strengthening rib strips 415 can also further enhance 41 overall stiffness of upper reinforcing plate, prevent
Only metal plate deforms；Due to space limitations, the cavity between upper reinforcing plate 41 and back door inner panel 10 is smaller, in coating, electricity
Swimming liquid is not easy to be discharged, so being provided with multiple liquid-leaking nozzles 416 on strengthening rib strip 415, effectively painting electrophoresis liquid can be discharged.
Further, mounting hole 412 is welded by project-welding nut technique and upper reinforcing plate 41, improve the intensity of welding with
And the stability of assembly, prevent the uneven caused strain cracking problem of power transmitting at mounting hole 412.
The lower end of upper reinforcing plate 41 extends downward with lower reinforcing plate 42, and lower reinforcing plate 42 is also and back door inner panel 10
The multistage bending plate of fitting, the periphery of bending plate are provided with the second flange 421, and the second flange 421 is bonded with back door inner panel 10
Place's setting solder joint.The span up and down of the setting of lower reinforcing plate 42, stiffening plate 40 is big, strengthens about 10 inflection point phase of back door inner panel
To weak position, the Integral modes and rigidity of back door inner panel 10 are also beneficial to, prevent back door inner panel 10 from generating abnormal sound, trembling
The problems such as moving, deforming.
Similarly, in order to facilitate the installation of, there are two second location holes 422 for setting on the plate body of lower reinforcing plate 42, in order to mitigate
Weight offers the second lightening hole 423 on the plate body between two second location holes 422.
