What is be described below is some in multiple embodiments of the invention, it is desirable to provide to the basic understanding of the present invention.And
It is not intended to the crucial or conclusive key element for confirming the present invention or limits scope of the claimed.
To make the object, technical solutions and advantages of the present invention clearer, further is made to the present invention below in conjunction with the accompanying drawings
Detailed description.
Fig. 1 is the design sketch of the front cover lock force measuring device of an embodiment of the present invention.Fig. 2 is an embodiment of the present invention
Front cover lock force measuring device top view.Fig. 3 is the upward view of the front cover lock force measuring device of an embodiment of the present invention.
In Fig. 1~Fig. 3,1 represents the body structure frock of thin-walled.Body structure frock 1 is used to store vehicle front cover lock
Core 2.Front cover for vehicle lock core 2 is removed and is placed in after former mounting bracket in body structure frock 1, and by body structure frock 1
One face（A face in front is proximate in Fig. 1）It is fixed as one with protecgulum lock core 2 by way of welding etc..Body structure
Another face of frock 1（A face at rear is proximate in Fig. 1）On be provided with mounting hole 3, pass through the body structure work of mounting hole 3
1 is filled to be connected and fix with vehicle body.The lock core position for needing to ensure in installation casing structure frock 1 to be installed to after vehicle body the inside with
Former lock core position consistency.
Here, above-mentioned " face " for body structure frock 1 can refer to be assembled to Che Shanghou close to headstock that
Face, another face of body structure frock 1 can refer to be assembled to Che Shanghou close to that surface of the tailstock, and car is will be close to here
That face of head is referred to as " preceding surface ", will be close to that face of headstock into referred to as " rear surface ".
On two sides in addition to above-mentioned preceding surface and rear surface of body structure frock 1, pass through perforate etc.
Method cuts down material to reduce rigidity and increase deformation, thus constitutes variable shaped beam 4.Only illustrate in Fig. 1 on two side faces
The mode of perforate is carried out respectively.In addition to the mode of perforate, directly two side views can also be designed to it is narrow, thin, or
Person can also reach reduction rigidity and increase deformation purpose with the small material of rigidity or heat treatment method.
As shown in Figures 2 and 3,2 pieces of foil gauges, specifically, the deformation in side are fixed respectively on the variable shaped beam 4 of both sides
The first foil gauge 5 and the 3rd foil gauge 7 are fixed on beam 4 respectively, the second foil gauge 6 is fixed respectively on the variable shaped beam 4 of opposite side
With the 4th foil gauge 8, deformation piece can be separately fixed in the upper and lower surface of variable shaped beam.First foil gauge the 5~the 4th
Foil gauge 8 can be fixed on variable shaped beam 4 by modes such as stickup, welding.
Then, the foil gauge 8 of the first foil gauge the 5~the 4th is constituted into Wheatstone bridge according to the connected mode shown in Fig. 4, its
In, the resistance 9 in Fig. 4 is that the first foil gauge 5, resistance 10 are that the 3rd foil gauge 7, resistance 11 are that the 4th foil gauge 8, resistance 12 are
Second foil gauge 6.It is that four resistance constitute Wheatstone bridges by four pieces of foil gauges, takes medium voltage as output, using following
Formula ask for the pressure F that front cover lock is subject to：
F=Ku
Wherein, F is the pressure that front cover lock is subject to, and u is strain, and K is calibration value（It is known）.
So, by setting the foil gauge 8 of the first foil gauge the 5~the 4th on variable shaped beam 4 and constituting Wheatstone bridge, no
Destruction primary car structure is needed just to accurately measure the pressure F that front cover lock is subject to.
It is illustrated above for the front cover lock force measuring device of the present invention.Front cover lock power below for the present invention is surveyed
Amount method is illustrated.
The vehicle front cover lock force measuring method of the present invention mainly comprises the steps：
Fixing step S101：Front cover for vehicle lock core 2 is placed in body structure frock 1 and makes the body structure frock 1
Fixed with vehicle body；
Variable shaped beam forming step S102：Two sides of the body structure frock 1 are formed into two variable shaped beams 4；
Foil gauge setting steps S103：The first foil gauge 5 is fixed in the way of pasting or weld on the variable shaped beam 4
~the four foil gauge 8；
Electric bridge forming step S104：By the 5~the 4th foil gauge of the first foil gauge, 8 pass through the favour stone electricity that is electrically connected to form
Bridge；
Pressure measxurement step S105：Obtain locking the power being subject to before automobile by measuring the output voltage of the electric bridge.
Wherein, in fixing step S101, the preceding surface of front cover for vehicle lock core 2 and body structure frock 1 is fixed into one
Body, here as fixed mode can be using bonding, welding etc..Also, set and install on the rear surface of body structure frock 1
Hole 3, mounting hole 3 with to be installed to the lock core position after vehicle body with by way of former lock core position consistency by casing knot
Structure frock 1 is fixed on vehicle body.
In variable shaped beam forming step S102, two sides of body structure frock 1 are become by reducing rigidity and increase
Shape forms variable shaped beam 4.For example, can carry out perforate to form variable shaped beam 4 by two sides to body structure frock 1,
Directly two side views of body structure frock 1 can also be designed to it is narrow, thin, or can also with the small material of rigidity or
Person's heat treatment method reduces rigidity and increase deformation purpose to reach.
Wherein, in foil gauge setting steps S103, respectively to be bonded or weld on two surfaces of two variable shaped beams 4
Mode fix 2 pieces of foil gauges, 2 pieces of foil gauges can be respectively formed in the upper and lower surface of variable shaped beam 4.
Utilize the vehicle front cover lock force measuring method of the invention described above, it is not necessary to which destroying primary car structure can just survey exactly
Measure the pressure that front cover lock is subject to.
Example above primarily illustrates vehicle front cover lock force measuring device and the vehicle front cover lock power measurement side of the present invention
Method.Although only the embodiment to some of present invention is described, those of ordinary skill in the art should
Understand, the present invention can be without departing from its spirit with implementing in scope in many other forms.Therefore, the example that is shown with
Embodiment is considered as illustrative and not restrictive, is not departing from the present invention spirit as defined in appended claims
And in the case of scope, the present invention may cover various modifications and replacement.
