When measuring height, the user stands on the scale body, aligns the head with the scale line, and then reads the corresponding scale line value, thereby achieving the purpose of measuring height.

[0021] The following is combined with Figure 1-3 This application is described in further detail.

[0022] The present application embodiment discloses a new type of medical body scale, referring to Figure 1-3 , including a weight scale 1, a height measuring mechanism 2 is fixed on the bottom frame of the weight scale 1, the height measuring mechanism 2 includes a vertical rod 21, a servo linear guide slide 22, a reference rod 23 and an infrared distance sensor 24, the vertical rod 21 is vertically fixed on the bottom frame of the weight scale 1, a connecting frame is integrally formed on the bottom frame of the weight scale 1, the vertical rod 21 is fixed to the connecting frame by a stud, the servo linear guide slide 22 is vertically fixed on the vertical rod 21, the reference rod 23 is slidably connected to the slide of the servo linear guide slide 22, a boss 25 is fixed on the top of the vertical rod 21, and the infrared distance sensor 24 is fixed to the bottom of the boss 25;

[0023] A cover 26 is also fixed to the side of the vertical rod 21, and a clearance groove 261 is opened on the surface of the cover 26. A digital display 3 and a remote control switch 4 are arranged on the side of the cover 26. A single-chip microcomputer controller is installed inside the digital display 3. The infrared distance sensor 24 and the weight scale 1 are electrically connected to the digital display 3. The remote control switch 4 is used to control the operation of the servo linear guide slide 22.

[0024] The cover 26 is also provided with a scale bar (not shown in the figure), which can also be used for manual reading in case of emergency.

[0025] Reference Figure 1 and Figure 3 The infrared distance sensor 24 includes a pair of infrared signal emitting diodes and receiving diodes fixed on the boss 25. In order to ensure that the infrared light can be well reflected, a reflective plate 5 is fixed on the side surface of the reference rod 23 corresponding to the infrared distance sensor 24.

[0026] Reference Figure 3 In order to ensure that the reference rod 23 can maintain a horizontal state, a T-shaped slide groove 6 is opened on the side wall of the slide of the servo linear guide slide 22, and the end of the base rod has a slider adapted to the T-shaped slide groove 6, and stop blocks 7 are fixed at the openings at both ends of the T-shaped slide groove 6 by screws.

[0027] The implementation principle of a new type of medical body scale in the present application embodiment is as follows:

[0028] The measurer raises and lowers the reference rod 23 to a rough height according to his / her own height through the remote control switch 4. Thereafter, the measurer stands on the weight scale 1 and stands upright against the cover 26 so that the reference rod 23 is pressed against the top of the head. After the preparation is completed, the infrared distance sensor 24 is controlled to work through the remote control switch 4. The infrared distance sensor 24 emits a beam of infrared light through the infrared signal emitting diode, which forms a reflection process after being irradiated to the reflective plate 5, and is reflected to the receiving diode to receive the signal. Then, the CCD image processing is used to receive the data of the time difference between the emission and the reception. After being processed by the signal processor, the distance to the reference rod 23 is calculated. The actual value displayed in the digital display 3 is the total height from the boss 25 to the weight scale 1 (this height is a fixed value, which is set at the factory) minus the distance of the infrared distance sensor 24, and then minus the height of the reference rod 23. This value is the actual height of the human body, and the measurement result is relatively accurate.

[0029] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, principle and application direction of the present application should be included in the protection scope of the present application.
