Abstract
The utility model discloses a kind of bottom backplates.Bottom backplate is included along the elongated hole of automobile longitudinal and front end connecting portion, the elongated hole and the front end connecting portion for the bottom backplate and subframe installation.The different length of automobile longitudinal can be adapted to by setting along the elongated hole of automobile longitudinal so that bottom backplate can be common to the different automobile types under same platform.
Description
Technical field
The utility model is related to automotive field, in particular to a kind of bottom backplate.
Background technology
In current passenger car, bottom backplate is passed through to be occurred frequently as part after sale or apolegamy part, and major function is
Engine sump tank, belt pulley are protected, prevents the shock of slungshot and grit.For identical platform different automobile types, bottom backplate is often
It cannot share, cause that its species is more, and yield is small.Therefore under conditions of design requirement is met, bottom backplate can be shared as far as possible
It is the focus of bottom backplate research.
Utility model content
The utility model proposes a kind of bottom backplate, the different automobile types that can be common under same platform.
According to the bottom backplate that the utility model proposes on one side, including the elongated hole along automobile longitudinal and front end
Connecting portion, the elongated hole and the front end connecting portion are used for the installation of the bottom backplate and subframe.According to the utility model
The bottom backplate proposed on one side, bottom backplate are equipped with multiple perforates in middle part.
The beneficial effects of the utility model are：Automobile longitudinal can be adapted to by setting along the elongated hole of automobile longitudinal
Different length so that bottom backplate can be common to the different automobile types under same platform.
Description of the drawings
It is explained with reference to the disclosure of the utility model.It is to be appreciated that the mesh that these attached drawings are merely illustrative
, and be not intended to and the scope of protection of the utility model is construed as limiting.In figure：Fig. 1 schematically illustrates new according to this practicality
The structure diagram of the bottom backplate of one embodiment of type.
Specific embodiment
It should be noted that " front/rear " that is referred to herein refers to along in automobile direction of advance in front or rear.
An embodiment according to the present utility model is shown according to Fig. 1, wherein can be seen that：Bottom backplate 10 is included along automobile
The elongated hole 1 of longitudinal direction and front end connecting portion 6, the elongated hole 1 and the front end connecting portion 6 are for the bottom backplate 10 and pair
The installation of vehicle frame.For identical platform different automobile types, the length of subframe longitudinal direction is often different, this just needs bottom backplate 10 to have
Flexible connecting structure, the connection structure disclosure satisfy that because of the different same platform different automobile types of longitudinal length.It is put down for same vehicle
Two kinds of vehicles (different power assemblies, different wheelbases) of platform can share bottom backplate according to the present utility model.The structure
Design meets vehicle performance requirement and general assembly installation requirement.The structure design is simple, has saved because different configuration vehicles are equipped with
More money bottoms backplate and the die cost generated, while do not increase cost per unit.
Installation point between bottom backplate 10 and subframe uses the form of slotted hole, disclosure satisfy that longitudinal different length
Installation requirements, maximum flexible installing.Elongated hole 1 is arranged on the rear end of the bottom backplate 10, convenient for the installation of bottom backplate.
In the perforate 4 of 10 middle part of bottom backplate, the needs of different dynamic assembly being disclosure satisfy that, ensureing its oil strainer, coolant is put
Perforate demand under oil draining bolt.It is high to longitudinally rigid requirement since bottom backplate 10 is variable in vehicle fore-and-aft distance, to this
Reinforcing rib 5 at middle part can strengthen 10 rigidity of bottom backplate and meet performance requirement, avoid the problem that generating vibrations noise.
When on general assembly line to the installation of bottom backplate 10, it is desirable that worker can both hands leave part carry out air gun fastener twist
Tightly.Rear alignment portion 2 and front end positioning region 3 are predetermined bit architecture of the bottom backplate 10 on general assembly line.The two of 10 front end of bottom backplate
Backplate 10 front end in bottom can first be hung over pull rod under leading portion vehicle body by a front end positioning region 3, such as hook（lower tie bar）
On, backplate 10 rear alignment portion 2 in bottom uses distribution with subframe（push pin）It is fixed, it can be achieved that worker after 3 points of pre-determined bits
Both hands leave part progress fastener and tighten operation, complete the installation of bottom backplate 10.Bottom backplate 10 first passes through the fixed rear end of distribution
Positioning region 2 and front end positioning region 3 carry out three point pre-determined bits with pull rod under subframe and vehicle body, then by using air gun to elongated hole
1 and front end connecting portion 6 carry out the urgent assembling of bolt.
The technical scope of the utility model is not limited solely to the content in above description, and those skilled in the art can be
On the premise of not departing from the utility model technological thought, to above-described embodiment carry out many variations and modifications, and these deformation and
Modification should all belong in the scope of protection of the utility model.
