[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is easy to use because the common detection value area has a low occupancy rate for all detection areas, but has a high occupancy rate for all pointer deflection areas on a finger-type gauge. A pointer type gauge with improved

[0002]

[Prior Art]

 Conventionally, as shown in the example of the pointer-type round water thermometer 3 for vehicles and the characteristic graph thereof shown in FIGS. 5A and 5B, this type of pointer-type gauge has a pointer in the entire pointer deflection range T. The unit runout width of 31 is uniform everywhere. That is, the detected value t (vertical axis) and the needle deflection range θt (horizontal axis) have a linear relationship M4 with a constant inclination α.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional pointer type gauge is extremely convenient as long as each detection value t is uniformly generated over the entire detection area Ts (that is, the entire pointer deflection area T). In reality, however, this does not occur, and each detection value t usually occurs separately with a detection value ts1 having a high occurrence frequency (or usage frequency) and a detection value ts2 having a low occurrence frequency. The area Ts1 occupied by the detection value ts1 having a high frequency normally has a narrow occupancy rate with respect to the entire detection area Ts (that is, the entire pointer deflection area T 1). Therefore, the conventional pointer-type gauge is inconvenient for practical use.

A specific explanation will be given by taking the pointer type round water thermometer 3 for a vehicle of FIG. 5 (a) as an example. In the figure, the total pointer deflection area T on the pointer type gauge 3 corresponding to the entire detection area Ts (50 ° C to 135 ° C) is the area 32 of 50 ° C to 120 ° C and the area of 120 ° C to 120 ° C. And a region 33 at 135 ° C. Of these, 50 ° C to 80 ° C is the start-up region or the overcool region, which is the emergency detection value region Ts21. 80 ° C to 120 ° C is the normal water temperature region and the overheat risk region, which is the normal water temperature region Ts1. 120 ° C to 135 ° C is an overheat region, and this region is also an emergency detection value region Ts22. That is, the normal water temperature range Ts1 occupies only 47% of the total pointer deflection range T, and conversely, the emergency detection value range Ts2 (Ts21, Ts22) which is not normally used does not correspond to the entire pointer deflection range T. 53%, which is extremely inconvenient in practical use.

The present invention pays attention to the problems of the above-mentioned prior art, and even if the regular detection value area Ts1 has a low occupancy rate with respect to the total detection area Ts, the total pointer deflection area T on the pointer type gauge 3 The purpose is to provide a pointer-type gauge that can have a high occupancy rate.

[0006]

[Means and Actions for Solving the Problems]

 In order to achieve the above object, the first invention will be described with reference to FIGS. 1 (a) and 1 (b). The entire pointer swing area T is a wide unit swing area T1 and a unit swing width. The region T2 has a narrower area.

According to the above configuration, the occupancy rate of the area T1 in the entire pointer deflection area T can be made wider than the occupancy rate of the area T2. Therefore, the area T1 can be made to correspond to the regular detection value area Ts1, and the pointer type gauge can be easily used.

A second invention is a device which utilizes the above-mentioned first invention and includes a control system, and when explained with reference to FIG. 4, it is connected to the sensor 1 via the microcomputer 2. In the pointer type gauge 3 described in 1, the microcomputer 2 divides the entire detection area Ts corresponding to the entire pointer deflection area T into a detection value area Ts1 corresponding to the area T1 and a detection value area Ts2 corresponding to the area T2. At the same time, the conversion formula f (t) from the detection value region Ts1 to the region T1 and the conversion formula g (t) from the detection value region Ts2 to the region T2 are stored in advance, and each detection value t from the sensor 1 is Conversion is performed by the corresponding conversion formula f (t) or formula g (t), and the pointer 31 is swung by only the converted value θt.

The above-mentioned configuration is a configuration utilizing the first invention, and according to this configuration, even if the regular detection value region Ts1 has a low occupancy ratio to the entire detection value region Ts, the regular detection value region Ts1 The area Ts1 is expanded by the microcomputer 2 and has a high occupancy rate with respect to the entire pointer deflection area T.

The third device is a device that also utilizes the first device and also includes a control system. If the same is described with reference to FIG. 4, the third device is connected to the sensor 1 via the microcomputer 2. In the pointer type gauge 3 according to claim 1, the microcomputer 2 sets the total detection area Ts corresponding to the entire pointer deflection area T to a plurality of detection value areas Ts1n corresponding to a plurality of different areas T1. Each mode Mn is divided into a plurality of detection value regions Ts2n corresponding to a plurality of different regions T2, and the conversion formula f (from the detection value region Ts1n to the region T1 is calculated for each mode M1 to Mn. t) n and the conversion expression g (t) n from the detected value area Ts2n to the area T2 are stored in advance, and the mode specifying signal Mi (i = 1 to n) from the mode specifying switch 4 separately provided. To call the designated mode Mi from the memory. In the designated mode Mi, each detected value t from the sensor 1 is converted by the corresponding conversion expression f (t) i or expression g (t) i, and the pointer 31 is swung by the converted value θt. And

According to the above configuration, in the case where a plurality of detection value regions Ts1 (Ts1n) in different ranges desired to be detected exist in all the detection value regions Ts, a plurality of specifiable values corresponding to the detection value regions Ts1 can be specified. Since the individual modes Mn are set, for each designated mode Mi, even if the designated regular detection value region Ts1i has a low occupancy ratio to the entire detection value region Ts, the designated regular detection value region Ts1i The area Ts1i is enlarged by the microcomputer 2 and has a high occupation rate with respect to the entire pointer deflection area T.

A fourth aspect of the present invention is an aspect utilizing the above third aspect of the invention. Similarly, referring to FIG. 4, when the microcomputer 2 inputs the mode designation signal Mi from the mode designation switch 4, The positions and widths of the regions T1 and T2 may be changed so that the regions T1 and T2 have positions and widths that match the detection value regions Ts1i and Ts2i of the designated mode Mi.

In each of the regions T, T1 and T2 of the first to third inventions, there is no mention of the presence or absence of scales. This is because the first to third devices include a measurement in which the scale is directly read in the area T and a measurement in which the swing width of the pointer 31 in each of the areas T1 and T2 is visually evaluated. By the way, in the configuration of the third invention, the direct reading measurement is more convenient than the sensory evaluation measurement. Therefore, it was decided to display the scales, but fixed display is not applicable, so it was decided to deal with this in the fourth invention.

That is, according to the above configuration, the positions and widths of the regions T1 and T2, which are different depending on each designated mode Mi, can be changed to the positions, widths, and the like that match the designated mode Mi. In the sensory measurement for the third invention, if the blinking lamps corresponding to the number of modes are provided on the display plate, the positions and the entire widths of the regions T1 and T2 can be roughly represented. This sensory measurement is possible even without such a lamp (detailed description is omitted).

【Example】

 An embodiment of the present invention will be described in detail below with reference to FIGS. Incidentally, FIG. 5 is also a view for explaining a conventional pointer type gauge by itself. Therefore, FIGS. 1 to 4 correspond to FIG. 5 described in the section of the related art, and all are diagrams of an example of a pointer-type round water thermometer 3 for a vehicle. The pointer type gauge according to the present invention need not be limited to a round shape or a water temperature gauge, and can be applied to various pointers such as a longitudinal movement pointer, a pressure gauge, a speedometer, and a position indicator.

FIG. 1 is a diagram showing a first embodiment of the first invention, in which the entire pointer deflection area T 1 of the water temperature gauge 3 is composed of an area T 1 with a wide unit deflection width and an area T 2 with a narrow unit deflection width. Has been. The region T1 is a normal water temperature region of 80 ° C to 120 ° C, while the region T2 is a starting time region or an overcool region T21 of 50 ° C to 80 ° C and an overheat region T22 of 120 ° C to 135 ° C. It consisted of and. This is because the region T1 is a region that is always visible to the vehicle operator and is enlarged to facilitate reading.

FIG. 2 is a diagram showing a second embodiment, in which a region T1 is a starting time region of 50 ° C. to 80 ° C. and an overcooling region, while a region T2 is a temperature range of 80 ° C. to 120 ° C. It was composed of a normal water temperature region and an overheat region of 120 ° C to 135 ° C. This is a special example, but it is effective if it is installed in a vehicle that operates in cold regions or extremely cold regions (especially construction heavy machinery that performs heavy load work) where start-up time and overcooling are problems.

FIG. 3 is a diagram showing a third embodiment, in which a region T1 is an overheat dangerous region of 100 ° C. to 120 ° C., while a region T2 is a starting time region of 50 ° C. to 100 ° C. Further, it is composed of an overcool region and a normal water temperature region T21, and an overheat region T22 of 120 ° C to 135 ° C. This is also a special example, but it is effective if it is installed in a vehicle (especially a heavy construction machine that performs heavy load work) operating in tropical areas or extreme heat areas where overheating is a problem.

The region T1 in the first invention has been described as a normal water temperature region or the like in the description other than the scope of claims for utility model registration, but as will be understood from the second and third embodiments described above. , Especially refers to the area you want to measure. That is, any detection region can be the main region T1 depending on the purpose, and this is called the region T1 in the present invention. The same applies to the second to fourth inventions.

FIG. 4 is a diagram showing an embodiment of the second invention. Since the figure also shows a practical example of a third invention to be described later, it may be difficult to refer to it. In the figure, the embodiment of the second idea is configured as follows.

A pointer type gauge 3 based on the first invention (for example, each embodiment of FIG. 1, FIG. 2 or FIG. 3 described above) is connected to the sensor 1 via the microcomputer 2. The microcomputer 2 stores in advance the entire detection area Ts, the detection value area Ts1, and the detection value area Ts2 corresponding to the entire pointer deflection area T, the area T1, and the area T2 which have already been explained in the first invention. is doing. Further, as already described in the first invention, the detected value t corresponding to the detected value area Ts1 is expanded and swung in the area T1, so that the detected value t corresponding to the detected value area Ts2 is changed to the area T2. Then, a conversion formula f (t) from the detection value region Ts1 to the region T1 and a conversion formula g (t) from the detection value region Ts2 to the region T2 are stored in advance so that the pointer 31 is reduced and shakes. .. Therefore, when the detection value t is input from the sensor 1, the microcomputer 2 first determines whether the detection value t 1 is in both regions Ts1 or Ts2. Then, based on this result, the detected value t is converted into the guide deflection range θt by the corresponding conversion formula f (t) or the formula g (t), and the guide 31 is swung by this value θt.

According to the present embodiment, in the second invention, if the detected value t is in the range of the region T1, the pointer 31 naturally expands and shakes, and conversely if the detected value t is in the range of the region T2. The pointer 31 naturally contracts and swings, so that the pointer 31 can be reasonably fitted to each pointer type gauge of the first invention. Note that the conversion formulas f (t) and g (t) are respectively appropriately set as shown by the characteristics M1 to M3 represented by a plurality of linear equations in each of the above-mentioned (b) diagrams of FIGS. 1 to 3. In the applicable range, the conversion formula f (t) includes the conversion formula g (t), and conversely, the conversion formula g (t) includes the conversion formula f (t).

As described above, FIG. 4 is also a diagram showing an embodiment of the third invention. In the figure, the embodiment of the third invention is constructed as follows.

A pointer type gauge 3 based on the first invention is connected to a sensor 1 via a microcomputer 2. Incidentally, in order to make the following description easy to understand, first, a plurality of virtual display modes Mn of the pointer type gauge 3 will be described. For example, the characteristics relating to the regions T1 and T2 represented by a plurality of linear expressions shown in each of FIGS. 1, 2, 3 and / or 5 (b) described above are set to the mode M1 (FIG. 1). , Mode M2 (FIG. 2), mode M3 (FIG. 3) and mode M4 (FIG. 4). These may have at least two modes, but in this embodiment, all modes M1 to M4 are adopted as shown in FIG.

That is, the microcomputer 2 corresponds to the total pointer deflection area T and the areas T1 and T2 of each of the modes M1 to M4, and the total detection area Ts and each of the four detection value areas Ts11 to Ts11. Ts14, Ts21 to Ts24 are stored in advance. Further, the detection value t corresponding to the detection value areas Ts11 to Ts14 is enlarged and shaken in the area T1, while the detection value t corresponding to the detection value areas Ts21 to Ts24 is reduced in the area T2. The conversion formulas f (t) 1 to f (t) 4 from the detection value regions Ts11 to Ts14 to the region T1 and the conversion formula g (t) from the detection value regions Ts21 to Ts24 to the region T2 so as to swing. 1 to g (t) 4 are stored in advance. The microcomputer 2 is additionally provided with a mode designation switch 4, and an operator switches the switch 4 to designate a desired mode Mi (provisionally referred to as mode M2) from the modes M1 to M2. You can do it. Therefore, when the mode designating signal M2 is input to the microcomputer 2 from the mode designating switch 4, the designated mode M2 is called from the memory. Next, when each detection value t from the sensor 1 is input to the microcomputer 2, the microcomputer 2 calculates each detection value t by the conversion formula f (t) 2 or g (t) 2 of the designated mode M2. It is converted into a pointer deflection width θ t, and the pointer 31 is swung by this value θ t. The same applies to the other modes M1, M3, and M4.

That is, according to the present embodiment, by appropriately setting the content and the number of each mode Mn, one pointer-type gauge can be used for detection with high accuracy and according to various purposes. It will be easier to implement.

In FIG. 4, the embodiment of the fourth invention is constructed as follows. When the scale is displayed on the finger type gauge of the third invention, when the microcomputer 2 inputs the mode designating signal Mi from the mode designating switch 4, the areas T1 and T2 are the detection value area Ts1i of the designated mode Mi, The positions and widths of the regions T1 and T2 are changed so that the positions and widths match Ts2i. In order to achieve the above configuration, it is needless to say that the pointer type gauge is provided with a variable display element such as an EL element controlled by the microcomputer 2.

That is, it becomes possible to change the positions and widths of the regions T1 and T2, which are different depending on each designated mode Mi, to positions and widths that match the designated mode Mi. The positions and widths of the regions T1 and T2 can be achieved not only by so-called scales but also by color classification or the like. Therefore, such scales and colors are also included in the configuration of the fourth invention.

According to the above-described embodiments, in any of the pointer type gauges of all the inventions, even if the normal detection value area has a low occupancy rate to the entire detection area, all pointer pointers are moved on the pointer type gauge. A high occupancy rate can be set for the area, and as a result, usability can be improved.
