DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0020] Figure 1 FIG. 1 is a schematic diagram of the structure of an electronic weight scale provided by an exemplary embodiment of the present application. Figure 1 As shown, the electronic scale includes a display module 2, a pressure sensor 3, a power supply module 4 and a data processing module 5 which are arranged on the electronic scale body 1.
[0021] The power supply module 4 is used to supply power to each component on the electronic scale body 1. The data processing module 5 is used to communicate with the mobile phone to obtain the benchmark data set by the user on the mobile phone application, and the benchmark data includes the target weight. The pressure sensor 3 is used to obtain the actual weight of the user when weighing. The data processing module 5 is used to determine the change range of the actual weight compared to the target weight based on the target weight and the actual weight. The data processing module 5 is used to visualize the change range. The display module 2 is used to display the visualized change range to the user.
[0022] Exemplarily, the data processing module 5 includes a data transmission module 51 and a visual display calculation module 52. The data transmission module 51 is used to connect to the mobile phone via Bluetooth to obtain the benchmark data set by the user on the mobile phone application. The visual display calculation module 52 is used to determine the change range of the actual weight compared to the target weight based on the target weight and the actual weight. The visual display calculation module 52 is also used to visualize the change range.
[0023] At present, many obese people or people who care about their weight will have psychological preparation and behavioral preparation before getting on the scale, and they will have an acceptable range for their weight. Fluctuations within the range are acceptable, but if they exceed the preset maximum value, they will feel a little sad and collapse. If the weight is reduced, they will be happy and want to share it. If the maximum value is exceeded, they will weigh themselves several times and mind if someone is watching. Some people care about the precise number of digits in the data, while some people do not care about the specific numbers and want to see changes. Existing scales cannot meet users' privacy needs.
[0024] In the above example, the data processing module 5 obtains the target weight set by the user on the mobile phone application. When the user weighs, the pressure sensor 3 obtains the actual weight. The data processing module 5 determines the change in the actual weight compared to the target weight based on the target weight and the actual weight, and visualizes the change so that the display module 2 displays the visualized change to the user. For users who have a need to lose fat or are very concerned about weight gain, since these users do not care about the specific weight number, they want to intuitively see the change in the current actual weight compared to the target weight. Therefore, the electronic weight scale provided in the present application displays the visualized change range to the user, which not only enables the user to not expose his weight when weighing, but also enables the user to intuitively see the changes in his weight, so as to grasp his progress in fat loss, so as to take corresponding actions as needed.
[0025] For example, there are four pressure sensors 3, and one pressure sensor 3 is fixedly arranged at each vertex of the side of the electronic scale body 1 facing the user's foot area (which can be called the front side of the electronic scale body 1), so as to more accurately obtain the user's actual weight. Figure 6 As shown, a shell is also provided on the front of the electronic scale body 1, and the shell is used to protect various components provided on the electronic scale body 1, and the foot-operated area is located on the shell.
[0026] Exemplarily, the power supply module 4 is disposed on a side of the electronic scale body 1 facing the user's foot area.
[0027] Exemplarily, the power supply module 4 is provided with a USB port and is charged via a USB data cable; alternatively, the power supply module 4 provides power to the electronic weight scale via an installed battery.
[0028] Exemplarily, the data processing module 5 is arranged on a side facing the user's foot-stepping area.
[0029] In a feasible design, the benchmark data also includes a maximum value of the weight floating range and a minimum value of the weight floating range, wherein the target weight is less than the maximum value, the target weight is greater than the minimum value, and the absolute value of the difference between the maximum value and the target weight is the same as the absolute value of the difference between the minimum value and the target weight; The data processing module 5 is also used to establish a one-dimensional coordinate axis with the target weight as the origin and the maximum value and the minimum value as the endpoints; The data processing module 5 is also used to construct a first area of a preset shape according to the one-dimensional coordinate axis. The first area is provided with a center point, the center point represents the target weight, one end of the first area represents the maximum value, the other end of the first area represents the minimum value, and the direction from the center point to the end of the first area representing the maximum value is set as a positive direction (see Figure 2 ), the direction from the center point to the end of the first region representing the minimum value is set to the negative direction (see Figure 3 ); The data processing module 5 is used to visualize the change range, including: The data processing module 5 is used to determine the difference between the maximum value and the target weight, and take the absolute value of the difference as the maximum amplitude; The data processing module 5 is used to determine a first ratio of the change range to the maximum range if the actual weight is greater than the target weight; The data processing module 5 is used to determine the length of a first status bar extending in a positive direction starting from the center point of the first area according to the first ratio, and the color of the first status bar is different from the color of the first area.
[0030] Exemplarily, the preset shape is a rectangle or a rounded rectangle.
[0031] In a feasible design, the data processing module 5 is used to determine a second ratio of the change amplitude to the maximum amplitude if the actual weight is less than the target weight; The data processing module 5 is used to determine the length of a second status bar extending in a negative direction from the center point of the first area according to the second ratio, and the color of the second status bar is different from the color of the first area.
[0032] It should be understood that the data processing module 5 may also take the absolute value of the difference between the minimum value and the target weight as the maximum amplitude.
[0033] Exemplarily, the color of the first status bar is different from the color of the second status bar, which helps the user to intuitively determine whether his actual weight has increased or decreased compared to the target weight.
[0034] In the above example, the length of the status bar is used to visually display the change in actual weight compared to the target weight. This not only prevents other users from seeing the actual weight number, but also allows users to understand the distance between their actual weight and the target weight, thereby better guiding their fat loss actions. In addition, users can also judge whether their actual weight has increased or decreased compared to their target weight by which side of the center the status bar is located.
[0035] On the other hand, users can set a customized target weight and weight range. While meeting the user's personalized needs, they can receive corresponding reminders through information feedback from the status bar to help them achieve their fat loss goals.
[0036] In a feasible design, an emotional interaction module 6 is also included; The emotional interaction module is used to determine the content of the output voice according to the size relationship between the actual weight and the target weight, and the voice is used to remind the user that the actual weight exceeds the target weight or is less than the target weight; or, The emotional interaction module is used to determine the content of the output speech according to the size relationship between the actual weight, the maximum value and the minimum value.
[0037] Exemplarily, the emotion interaction module 6 includes a speaker, and the emotion interaction module 6 outputs speech through the speaker.
[0038] For example, if the actual weight is greater than the target weight, the output voice is "Your current weight is greater than the target weight, so pay attention to losing weight"; if the actual weight is less than or equal to the target weight, the output voice is "Your current weight is well maintained."
[0039] For example, if the actual weight is greater than or equal to the maximum value, the voice output is "Oh my God, what delicious food have you eaten recently? You are much over your target weight"; if the actual weight is less than the minimum value, the voice output is "Oh my God, the recent weight loss effect is so good, you are awesome" or "unbelievable".
[0040] The above settings for the voice content can be designed according to the needs, and this application does not limit this.
[0041] For users who need to lose fat or care about their weight, the electronic scale is not only a measurement tool, but also a partner in their weight management journey. The above example uses the emotional interaction module to achieve emotional interaction or support with users, and better meet users' emotional needs through personalized feedback such as friendly language, encouraging voices, and weight loss suggestions, thereby enhancing the emotional experience of using the electronic scale.
[0042] In a feasible design, a vibration module 7 is also included; The vibration module 7 is used to determine whether to initiate vibration or the number of vibrations according to the size relationship between the actual weight and the target weight; or, The vibration module 7 is used to determine whether to initiate vibration or the number of vibrations according to the actual body weight, the magnitude relationship between the maximum value and the minimum value.
[0043] Exemplarily, the vibration module 7 includes a vibration motor, and the vibration module 7 provides a vibration sensation to the user through the vibration motor.
[0044] For example, if the actual weight is greater than the target weight, it is determined that vibration is initiated, or vibration is performed once; if the actual weight is less than or equal to the target weight, it is determined that vibration is not initiated, or vibration is performed twice.
[0045] For another example, if the actual weight is greater than or equal to the maximum value, it is determined to initiate vibration, or to vibrate once; if the actual weight is less than the minimum value, it is determined not to initiate vibration, or to vibrate twice.
[0046] The above-mentioned determination of whether to initiate vibration or the number of vibrations by the vibration module 7 can be designed according to actual needs, and this application does not limit this.
[0047] The above example provides users with emotional interaction and positive feedback through the vibration module. For example, when the user reaches the target weight for fat loss or gains too much weight, the vibration module initiates vibration to prompt the user in an obscure way, thereby improving the effect of protecting privacy.
[0048] In a feasible design, a touch switch 8 is also included; The touch switch 8 is used to start the electronic scale when the user stands on the foot area of the electronic scale.
[0049] For example, there are three touch switches 8, which are arranged side by side on the side of the electronic scale facing the user and opposite to the foot-operated area, so that when the user stands on the electronic scale, the three touch switches are simultaneously touched in the foot-operated area to start the electronic scale, thereby improving the accuracy of starting the electronic scale.
[0050] In a feasible design, the data processing module 5 is also used to count the actual weights of the users within a preset number of times; The data processing module 5 is also used to generate a trend graph according to each actual weight; The display module 2 is used to display the trend graph to the user.
[0051] The above example displays a trend chart to the user through the display module 2, so that the user can intuitively see the trend changes of his actual weight, so as to better understand the progress of his own fat loss and the effect of his efforts.
[0052] The data processing module 5 can also generate other forms of charts so that users can intuitively see the changes in their actual weight, and the design can be based on actual needs.
[0053] In one possible design, Figure 4 As shown, the display module 2 includes a display screen 21 and a display screen support frame 22; The display screen support frame 22 is embedded in the electronic scale body 1 and is used for the user to step on the side for weighing; The display screen 21 is embedded in the display screen support frame 22 .
[0054] In the above example, the display screen is firmly fixed on the electronic scale body 1 by being embedded in the display screen support frame.
[0055] The display area of the display screen is used to display the change range or trend graph, and the display area is a partial area of the display screen.
[0056] For example, the display screen uses light emitting diodes In a feasible design, the display module 2 includes a projection device; The projection device is used to display the extent of changes after visualization to the user by means of projection or virtual reality augmented reality.
[0057] The above examples use projection technology or virtual reality augmented reality technology, and the weight scale can map the data onto the wall or other large screens to provide a larger and more intuitive display experience. This design enables users to observe their body fat and weight status more clearly, enhancing the visibility and comprehensibility of the data.
[0058] In a feasible design, the data processing module 5 is also used to send the actual weight to the mobile phone application so that the user can accurately check his or her actual weight.
[0059] For example, a QR code is provided on the electronic weight scale, and the mobile phone scans the QR code to enter the program (i.e., mobile phone application) to set the target weight, maximum value, and minimum value.
[0060] For example, the positions of the components of the electronic weighing scale are as follows: Figure 5 As shown. A pressure sensor 3 is provided at each vertex corner of the front of the electronic scale body 1. A power supply module 4 is provided between two pressure sensors 3, and a display module 2 is provided between the other two pressure sensors 3. A vibration module 7 is provided on the side of the power supply module 4 adjacent to the display module 2. Three side-by-side touch switches 8 are provided on the side of the vibration module 7 adjacent to the display module 2. An emotional interaction module 6 is provided on the side of the three side-by-side touch switches 8 adjacent to the display module 2. A data processing module 5 is provided on the side of the display module 2 facing the ground.
[0061] Exemplarily, the power supply module 4 is electrically connected to the other components of the electronic weight scale to provide power. The pressure sensor 3 is respectively connected to the data processing module 5, the vibration module 7 and the emotional interaction module 6 for transmitting the actual weight. The data processing module 5 is respectively connected to the vibration module 7 and the emotional interaction module 6 for transmitting the target weight, the maximum value and the minimum value. The data processing module 5 is electrically connected to the display module 2 for controlling the display module 2 to display a visualized graphic.
[0062] It should be understood that the connection method between the various components can be designed according to actual needs, and this application will not go into details here.
[0063] The working process of the electronic weight scale provided by this application is provided below: The data transmission module 51 receives the target weight, maximum value and minimum value set by the user, determines a one-dimensional coordinate axis, and constructs a first area according to the one-dimensional coordinate axis. Figure 6 When the user is on the electronic weight scale shown in the figure, the touch switch 8 is activated, the pressure sensor 3 obtains the actual weight of the user, and transmits the actual weight to the visual display calculation module 52. The visual display calculation module 52 calculates the change range of the actual weight compared with the target weight based on the target weight set by the user. The change range is converted into a status bar and displayed in the display area, such as Figure 7 As shown. When the user's actual weight reaches the target weight set by himself, the speaker of the emotional interaction module 6 will feedback encouraging voice, such as "unbelievable!"; when the user's actual weight exceeds the target weight set by himself, the vibration module 7 will vibrate to remind the user that he has not reached his goal. The specific weight data is not displayed during the weighing process, avoiding the embarrassment of weight when weighing with others. After the weighing is completed, the data transmission module 51 can transmit the actual weight to the mobile phone, so that users in need can check the specific value of the actual weight in time.
[0064] The present application aims to visually display the change range of the actual weight based on the target weight when weighing through a new display method, so that other users can not see the weight number, and can also visually see the difference between the current actual weight and the target weight. In order to calculate and display the change range of the actual weight relative to the target weight, the electronic scale has a built-in data processing module, which processes the data based on the algorithm, can accurately measure the actual weight of the user, and compare it with the preset target weight, and calculate the percentage of the change range or other forms of quantitative indicators. The above example uses an LCD screen to convert the change range into other visual elements such as graphics and charts, so that the electronic scale has the ability of visual display to present the change range to the user in a visual form. So that the user can intuitively understand his fat loss progress and the gap between the current actual weight and the target weight. It can be seen that the present application designs an intuitive and easy-to-understand user interface in the display module by selecting appropriate graphic elements, colors, layouts, etc., so that the user can clearly understand the information of the change range and take corresponding actions as needed to meet the personalized needs of the user.
[0065] In addition, in order to meet the emotional interaction between the electronic scale and the user, the electronic scale also has a built-in vibration module and an emotional interaction module, so that the user can get sound and vibration feedback when the weight reaches the target weight or exceeds the target weight too much.
