Specific embodiment
Fig. 1 is the schematic perspective view of the bottom backplate mechanism of embodiment according to the present utility model, is shown
In the case where vehicle chassis is placed upward, the installation condition of bottom backplate mechanism；Referring to Fig. 1, one is present embodiments provided
Zhong Di backplate mechanism 100, bottom backplate mechanism 100 are installed below the chassis of vehicle, the front end and rear end point of bottom backplate mechanism 100
It does not extend at the front vehicle wheel 201 of vehicle and the rear wheel 202 of vehicle；The both lateral sides of bottom backplate mechanism 100, that is, its left side
Right two sides extend respectively at the left side wheel of vehicle and the right side wheels of vehicle；Bottom backplate mechanism 100 covers chassis.
The utility model inventors have found that a main cause for causing motor vehicles traveling intermediate fuel oil consumption big is
Component shape below its chassis is irregular, generates some broken vortex, these components in vehicle travel process is caused to generate very
Big windage, so that vehicle needs to consume a large amount of fuel oil to overcome this windage.
For this purpose, the utility model installs bottom backplate mechanism 100 between the front vehicle wheel 201 and rear wheel 202 of vehicle chassis,
And bottom backplate mechanism 100 is extended to the right side wheels of vehicle by the left side wheel of vehicle, thus by most of bottom of vehicle
The component that big windage is easy to produce below chassis is carried out opposing seal to realize by disk covering, and realizing reduces motor vehicles row
Windage during sailing.And calculated according to correlation formula, the pneumatic air resistance coefficient of every reduction by 10%, oil consumption just has 5% reduction,
After the bottom backplate mechanism 100 of the utility model is installed, air resistance coefficient reduces by 0.0243, and oil consumption reduces 0.3087L/100km, dioxy
Change carbon emission and reduces 5.127g/km.
Referring to Fig. 1, further, bottom backplate mechanism 100 is mainly spliced to form by muti-piece plate-like piece.
It is spliced to form by muti-piece plate-like piece, can sufficiently reduce bottom backplate mechanism 100 in manufacture, transhipment and installation process
Volume, consequently facilitating manufacture and assembly.
Fig. 2 is the schematic perspective view of the right front board；Fig. 3 is the schematic perspective view of the left front panel；Fig. 4 is described
The schematic perspective view of right back board；Fig. 5 is the schematic perspective view of the left back board；Referring to Fig. 1 to Fig. 5, further, bottom shield
The top surface towards vehicle chassis of trigger structure 100, which is recessed downwards, forms recessed portion 101；Correspondingly, the top with bottom backplate mechanism 100
The downwardly convex formation lug boss 102 in bottom surface of the opposite bottom backplate mechanism 100 in face；The shape of lug boss 102 and recessed portion 101 and
The position of opposite bottom backplate mechanism 100 is consistent, that is to say, that so that the bottom surface opposite with its top surface of bottom backplate mechanism is downward
Convex to form lug boss 102.
Recessed portion 101 can expand the installation space on chassis, make to install more multi-part below chassis, to improve motor vehicle
Performance, and at the same time, lug boss 102, which can be realized still, wraps up the component on chassis, reduces chassis windage；To make
Bottom backplate mechanism 100 can either expand the space that contains on chassis, and realize the effect for reducing chassis windage.
Referring to Fig. 1, further, lug boss 102 is to be unfolded along vehicle lengthwise direction towards the bottom surface below vehicle
Plane；102 lateral surface of lug boss between the bottom surface of bottom backplate mechanism 100 and the bottom surface of lug boss 102 is opposing projections
The inclined-plane of 102 inclined bottom surfaces.
By setting 102 lateral surface of lug boss on the inclined-plane of 102 inclined bottom surface of opposing projections, make vehicle travel process
The windage generated below middle chassis adequately reduces as far as possible.
Referring to Fig. 1 to Fig. 5, further, the bottom surface of lug boss 102 forms multiple long striped grooves 103, long striped groove
103 are recessed towards chassis direction.
The integral slab surface intensity of bottom backplate mechanism 100 can be improved in long striped groove 103, and especially strip-shaped groove is more
Item and in the case where being arranged along vehicle lengthwise direction, more can be improved the plate face intensity of bottom backplate mechanism 100.
Further, plate-like piece covers the fuel tank of vehicle or/and canister, or package.
Specifically, referring to fig. 2 to Fig. 5, further, bottom backplate mechanism 100 includes: left front panel 104, right front board 106, a left side
Back plate 105 and right back board 107.Left back board 105 and right back board 107 can be used to cover the fuel tank of vehicle or/and canister.
Plate-like piece can play the fuel tank of vehicle and canister package to its protective effect, to improve anti-below chassis
Shield property can prevent motor vehicles traveling road surface sharp objects at rugged section from scraping to fuel tank especially to the package of fuel tank
It touches, and causes fuel tank damage even oil leak.
The front left wheel 201 of 104 adjacent vehicle of left front panel is installed on chassis；The right front wheel of 106 adjacent vehicle of right front board
201 are installed on chassis；The rear left wheel 202 of 105 adjacent vehicle of left back board is installed on chassis；The right side of 107 adjacent vehicle of right back board
Rear wheel 202 is installed on chassis；Wherein, left front panel 104, right front board 106, left back board 105 and right back board 107 are mutually butted.
Referring to Fig. 1, further, the exhaust pipe 300 of vehicle is installed on chassis and from the headstock of vehicle to the tailstock of vehicle
Extend, exhaust pipe 300 is installed on chassis centre；Left front panel 104 and left back board 105 connect, left front panel 104 and left back board 105
Between exhaust pipe 300 and the left side wheel of vehicle；Right front board 106 and right back board 107 connect, right front board 106 and right back board
107 between exhaust pipe 300 and the right side wheels of vehicle.
To reduce cost, while still making bottom to reduce the making material of bottom backplate mechanism 100 by above-mentioned setting
Backplate mechanism 100 keeps it to reduce the performance of windage.
Referring to Fig. 1, further, further include headstock backplate 108, be mounted at chassis, headstock backplate 108 will be before vehicle
Chassis covering between bumper and vehicle front-wheel.
Cooperated by headstock backplate 108 and bottom backplate mechanism 100, subtracts the windage entered below chassis by headstock further
It is small.
In addition, the present embodiment additionally provides a kind of motor vehicles, the chassis of motor vehicles is equipped with aforementioned bottom backplate mechanism
100.Its function and corresponding effect are as previously mentioned, herein not further around stating.
So far, although those skilled in the art will appreciate that the more of the utility model have been shown and described in detail herein
A exemplary embodiment still, still can be according to the utility model public affairs in the case where not departing from the spirit and scope of the utility model
