Description
Technical field
The utility model relates to LOAD CELLS, a kind of vehicle-mounted LOAD CELLS that is applied to of saying so exactly, and this sensor can be suitable for the load-carrying of various vehicles and measure.
Background technology
LOAD CELLS, be mainly used in the dynamometry of weighing in industry and the communications and transportation, the low profile sensor of industry, what adopt usually is the odd-shaped cross section annular sensor, this annular sensor is with the structure of normal stress mode work with fluting around the cartridge type flexible member, four limit grooves are regulated usefulness as stress distribution, and are linear to improve output.At present, this annular sensor typical case range is 2000 tons to the maximum.
Also have a kind of portable axletree flat panel sensor of weighing that is, this sensor adopts aluminium alloy one-piece construction, and the back side mills out a plurality of grooves, and stress surface be dull and stereotyped, and typically range is 15 tons.
These two kinds of sensors all can be applicable to vehicle weighing, and wherein, annular sensor can be adapted to multiple commercial unit dynamometry, and range of application is wide, but its anti-bias load and side force are poor, influence measuring accuracy; The portable axletree flat panel sensor Stability Analysis of Structures of weighing be not vulnerable to the foeign element influence, but range is little; Annular sensor is the same with the vertical dull and stereotyped LOAD CELLS of portable shaft, all has bigger physical dimension, and particularly height all is about 45-50mm usually, and this installation to vehicle causes a lot of limitations.
Particularly in today of automotive industry high development, the making precision prescribed of vehicle is very high, vehicle-mounted LOAD CELLS is installed on the vehicle, can not have influence on the vehicle original structure, can not have influence on the setting of vehicle's center of gravity, installation requirement LOAD CELLS height≤10mm, therefore above-mentioned sensor all is not suitable for the supporting repacking of present vehicle.
The utility model content
Therefore, the utility model provides a kind of novel vehicle-mounted LOAD CELLS, and this sensor has little size, and highly low profile and the big range of weighing can be adapted to the repacking of existing vehicle.
Another purpose of the present utility model is to provide a kind of novel flat panel sensor of weighing, and this sensor utilizes the change of structure, has very big range in very little profile, can satisfy the repacking of multiple vehicle, and simple in structure, makes easily and installs.
Based on this, the utility model is achieved in that
A kind of novel flat panel sensor of weighing is characterized in that this sensor comprises resistance sensor, force-bearing table, strain beam and pedestal, and resistance sensor is realized the weight measurement of article by the stress of measuring its bearing article; Force-bearing table is a plate-like structure, the alleged weight body (also claiming load-carrying) of loading; The both sides of force-bearing table have strain beam, and resistance sensor is fixed on the strain beam, and the distortion of induction strain beam comes calculated load; The outside of strain beam is fixed with pedestal, by pedestal this sensor is fixed on the vehicle.
The California bearing ratio of force-bearing table load hour (being generally below 50 tons), resistance sensor is out of shape along with the distortion of strain beam, and produces electric signal output, can draw the weight of load-carrying exactly by calculating.
When the weight ratio of load-carrying is big, the strain beam distortion is big, even can cause distortion, load-carrying is very big to the influence of strain beam, pedestal, this sensor might can not be born the weight of load-carrying, can be provided with at least one power shunt this moment in the bottom of force-bearing table, when sensor is stressed, the power shunt is pressed down, flexibly be held on the pedestal, thereby power is diverted on the carriage or other parts that supports this sensor, makes sensor itself only be subjected to partial pressure, the range that can provide this sensor to weigh greatly.
Described power shunt, it has two or more, evenly is arranged at the bottom of sensor, the shunting of power when carrying out relatively large journey evenly.
Described power shunt, its preferably flexible member making is can carry out the buffering shunting of power effectively.
Described pedestal, when super large range (as 100 tons), it is provided with flexible structure or by the flexible part fixation of sensor, flexible structure or flexible part can cushion effectively, reduces in the design usually the requirement to pedestal rigidity.
Above-mentioned flexible structure is on the pedestal of sensor both sides, along pedestal vertically offer vertical slot, this vertical slot constitutes flexible structure, avoids when bearing than heavy the harmful effect that the small size pedestal brings inadequately because of rigidity.
Above-mentioned vertical slot according to the size of pedestal, is provided with one at least, and pedestal is when being provided with two above vertical slots, and vertical slot is staggered to be offered.
The utility model adopts above-mentioned structure, by of the setting of tabular force-bearing table in conjunction with strain beam, be arranged at the resistance sensor of the usefulness of weighing on the strain beam dexterously, can reduce the whole sensor size effectively, make and the utlity model has less size and profile, can be adapted to the repacking of existing vehicle.
And this sensor construction is simple, be convenient to install.
Under the big situation of load-carrying, can also power be shunted effectively by the setting of power shunt, can improve the range of weighing widely.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, enforcement of the present utility model is elaborated.
Shown in Figure 1, for the novel flat panel sensor of weighing that vehicle adopted that is installed on 100 tons of load-carryings is that example describes.
At first, the novel flat panel sensor of weighing mainly includes pedestal 1, strain beam 2, force-bearing table 3 and resistance strain plate 5 (resistance strain plate carries out the variable measurement of inductance as resistance sensor), force-bearing table 3 is the position of weighing, strain beam 2 carries out stress deformation according to the load-carrying of force-bearing table, wherein, four positions of strain beam 2 offer four grooves 6, be respectively arranged with resistance strain plate 5 in the groove, resistance strain plate 5 is measured according to the distortion of strain beam 2, and produce electric signal output, can pass through concrete weight to the detection computations load-carrying of electric signal.
When design, integral thickness≤the 10mm of the novel flat panel sensor of weighing, therefore, weigh 100 tons load-carrying, also power shunt bar 4 need be set in the bottom of force-bearing table 3, in embodiment shown in Figure 1,4 of power shunt bars are provided with one, also can as the case may be two or more power shunt bars be set.
If load-carrying is less than 100 tons, this moment, the novel flat panel sensor of weighing can bear load-carrying according to the design of itself, and the power shunt bar can be set.
Secondly, flexible isolation channel 7 need be set on each wide range, undersized pedestal 1, shown in Figure 1, two flexible isolation channels 7 all are set on each pedestal 1, and these two flexible isolation channels 7 are interspersed, with buffering that can the shape paired forces, avoid when load-carrying is excessive the harmful effect that small size pedestal rigidity deficiency is brought.
Flexible isolation channel also is to be provided with according to the concrete size of pedestal and applicable cases, can be provided with one, also can be provided with a plurality of; Simultaneously, less in load-carrying, for example during the situation below 100 tons, pedestal itself can bear load-carrying, and flexible isolation channel can be set, but when load-carrying is big, needs the buffer protection of flexible isolation channel to pedestal.
The above only is preferred embodiment of the present utility model, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
