Description

Handheld Rangefinder

technical field

The utility model relates to a distance measuring device, in particular to a hand-held distance measuring device.

Background technique

The handheld range finder is a portable distance measurement tool, which is widely used in construction, interior decoration and other fields. When measuring, the user only needs to aim at the target to be measured, press the measurement key, and the measurement result will be automatically displayed on the display screen of the rangefinder. Normally, when the user holds the rangefinder to measure the horizontal/vertical distance from the front object or the object above the rangefinder, the data direction displayed on the display screen is consistent with the user's data reading direction, and the user can read the data conveniently and correctly. Get measurement data. But when the user holds the range finder 10' to measure the vertical downward distance, the data direction displayed on the display screen 14' is completely opposite to the user's data reading direction, as shown in Figure 1, at this time not only Can cause visual clutter to the user and is likely to cause errors when the user reads the measurement data.

Utility model content

The purpose of the utility model is to provide a hand-held distance measuring instrument which is convenient and comfortable to read and is not prone to reading errors.

In order to achieve this purpose, the handheld rangefinder in the utility model comprises a housing, a distance measurement module located in the housing, a processor connected to the distance measurement module, a display on the housing device, the handheld distance meter also includes a display rotation trigger unit, the display rotation trigger unit is connected to the processor, and one is connected to the display device and can control at least part of the display device Display rotation processing unit for display content rotation.

The hand-held rangefinder disclosed in the utility model uses a display rotation trigger unit so that when the direction of the display content on the display device is inconsistent with the user's reading direction, the trigger display content rotates to make it consistent with the user's reading direction. The reading directions are consistent, so that the user is more convenient and comfortable when reading the displayed content, and the problem of reading errors is not easy to occur.

Detailed ways

Referring now to FIG. 2 and FIG. 3 , a handheld distance meter 10 includes a housing 20 , a keypad 15 and a display screen 14 located on one surface of the housing 20 . A distance measurement module 12 and a processor 11 are installed inside the housing 20 , and the processor 11 is connected to the distance measurement module 12 so as to control the distance measurement module 12 to perform distance measurement and display the measurement result on the display screen 14 . Patent Nos. US2006/0023199A1, US2005/0172696A1, US7023531B2, and US6864966B2 disclose various implementations of the distance measuring part of the rangefinder, which are cited here as references for the present utility model and will not be repeated here.

The handheld rangefinder 10 also includes a display rotation trigger unit and a display rotation processing unit 13, the display rotation trigger unit is connected with the processor 11, and the display rotation processing unit 13 is connected with the processor 11 and also with the display screen 14 connected. When the display content on the display screen 14 needs to be rotated, the display rotation trigger unit will trigger and generate a trigger signal to the processor 11, and the processor 11 will start the display rotation processing unit 13 to perform corresponding processing, so that the display on the display screen 14 Part or all of the content is rotated. The display rotation processing unit 13 includes a display controller (not shown in the figure) to control the direction of the display content on the display screen. As long as the display mode of the display controller is modified, the direction switching of the display content on the display screen can be realized. In other implementation manners, the display rotation processing unit 13 can also be integrated with the processor 11 .

The display rotation trigger unit may include a key 151 which can be directly operated by the user, which is located in the key area 15 . Preferably, when needed, the user presses the button 151, and the measurement data part 141 in the displayed content on the display screen 14 is rotated by 180 degrees, as shown in FIG. 3 . Figure 4 shows a flow chart for realizing the 180-degree rotation of the display content. First, press the button 151 to generate a display rotation trigger signal. After receiving the signal, the processor 11 immediately modifies the display mode of the display controller, and the display control The instrument control display screen 14 displays the measured data after rotation. However, the icon 142 representing the measurement start point position on the rangefinder body currently used by the rangefinder does not rotate together with the measurement data part 141, and the display direction of the icon 142 is relative to the The rangefinder body remains the same. In this embodiment, a case where part of the displayed content is rotated is described, and those of ordinary skill in the art may also conceive that in other implementation manners, all displayed content on the display screen may be rotated.

Those of ordinary skill in the art can also easily imagine that the rotation of the displayed content at any angle can be realized through the combination of software programming and hardware. As shown in FIG. 5 , when the button 151 is pressed, the processor 11 receives a display rotation trigger signal, processes the original image data, and at least part of the displayed content on the display screen rotates by a corresponding angle. Preferably, when the button 151 is pressed once, the measurement data part 141 can be rotated by 90 degrees accordingly, and the user can rotate the measurement data part 141 by 90 degrees, 180 degrees, or 270 degrees according to his needs. The rotatable display content is not limited to measurement data, and may also be other suitable display content parts that require a rotation direction.

The display rotation trigger unit in this embodiment may also include a direction sensing device 16. When the gravitational acceleration direction of the handheld rangefinder 10 changes, the direction sensing device 16 will automatically transmit a display rotation trigger signal to the processor 11. , the processor 11 modifies the display mode of the display controller, so that the displayed image on the display screen is rotated by 180 degrees. When the rangefinder 10 turns 180 degrees from the position where the measurement signal is emitted upwards to the position where the measurement signal 21 is emitted downwards, the direction sensing device 16 senses the change in the direction of the acceleration of gravity, and automatically triggers the display on the display screen. The image is rotated 180 degrees; when the rangefinder 10 is turned over 180 degrees from the position where the measuring signal 21 is emitted downwards and then changed to the position where the measuring signal is emitted upwards again, the direction sensing device 16 perceives the change of its gravitational acceleration direction again so that Trigger the display image to rotate 180 degrees again. When the handheld rangefinder 10 is placed in a horizontal plane, the direction sensing device 16 does not function, and the display image can only be rotated by the manual key 151 at this time. The direction sensing device 16 is a sensing device capable of sensing the direction of gravitational acceleration, such as a mercury switch, a ball switch, an acceleration sensor chip, and the like. In other embodiments, there may be only one of manual rotation and automatic rotation of the displayed content.

The specific embodiments described above are only to illustrate the concept and principle of the present utility model, and are not intended to limit the content of the present utility model. Those of ordinary skill in the art can appreciate that, in addition to the above-mentioned preferred specific implementation, the utility model also has many other alternatives or modified implementations, and these alternatives or modified implementations are still within the scope of the present utility model within. The protection scope of the utility model is determined by the claims.
