Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0044] like Figure 1-11As shown, an electronic scale according to an embodiment of the present invention includes a scale housing 100, a load-bearing platform 200 and an electric control switching device. A weighing module 700 is provided on the scale housing 100. The electric control switching device is provided on the scale housing 100. The electric control switching device can drive the load-bearing platform 200 to contact or separate from the weighing module 700 according to a control signal. When the load-bearing platform 200 is in contact with the weighing module 700, it can be weighed by the weighing module 700.

[0045] The scale housing 100 may be in various shapes, such as Figure 1 、 2 As shown, the scale housing 100 can be rectangular, circular or in other shapes, and the supporting platform 200 can be disc-shaped or flat, and can be used as a cutting board. It should be noted that since the purpose of this design is to prevent the force applied during the cutting process from acting on the weighing sensor, the weighing module 700, in addition to the basic weighing sensor, can also include components such as plates, brackets, etc. that are arranged on the scale housing 100 and can be contacted and transmit the force to the weighing sensor, such as a panel on the scale housing 100.

[0046] With the electronic scale of the present invention, when the user needs to cut on the carrying platform 200, the carrying platform 200 is driven to separate from the weighing module 700 by operating the electric control switching device, so that when the user cuts on the carrying platform 200, the force applied will not be transmitted to the weighing module 700, and the weighing module 700 will not be damaged. When the cutting is completed and weighing is required, the carrying platform 200 can be driven to contact the weighing module 700 by operating the electric control switching device, and the weighing module 700 can weigh the objects on the carrying platform 200, which is convenient to use.

[0047] In some embodiments of the present invention, the electric-controlled switching device includes an input module 300, an electric-controlled displacement module 400 and a control module 500. The control module 500 is electrically connected to the input module 300 and the control module 500 respectively. The control module 500 can control the operation of the electric-controlled displacement module 400 according to the control signal input by the input module 300. The electric-controlled displacement module 400 can drive the supporting platform 200 to contact or separate from the weighing module 700. Specifically, there are four electric-controlled displacement modules 400, which are located at the four corners of the electronic scale to balance the force.

[0048] Among them, the input module 300 may include operation buttons, touch panels, etc., and the control module 500 may be composed of an MCU, CPU or PLC processing chip and its peripheral circuits. Furthermore, the electronic scale generally also includes a display module 600 and a processor. The processor here can be integrated with the control module 500, or two processing chips can be used separately. The following is explained as an integrated whole. The control module 500 is respectively connected to the display module 600 and the weighing sensor, so as to obtain the weight of the object on the load platform 200 based on the information fed back by the weighing sensor, and then displayed through the display module 600. The display module 600 can use an LCD touch screen, and the input module 300 can be integrated with the display module 600.

[0049] In some embodiments of the present invention, Figure 9 As shown, the electric-controlled displacement module 400 includes an electromagnetic drive component 410 and a first movable part 420 that can be adsorbed or repelled by the electromagnetic drive component 410. The control module 500 is electrically connected to the electromagnetic drive component 410. The electromagnetic drive component 410 is arranged on the scale housing 100. The first movable part 420 is movably arranged on the scale housing 100. The movement of the first movable part 420 can drive the supporting platform 200 to contact or separate from the weighing module 700.

[0050] Specifically, the electric-controlled displacement module 400 also includes a first mounting seat 430 arranged in the scale housing 100, and the electromagnetic drive component 410 is arranged in the first mounting seat 430. The first mounting seat 430 is provided with an extension port that allows the first movable part 420 to move. The electromagnetic drive component 410 includes an iron core and a coil wound on the iron core. The control module 500 is connected to the coil to control the current passing through the coil so that the iron core generates magnetism. The first movable part 420 is a magnetic top block. The polarity of the end of the magnetic iron core close to the first movable part 420 is opposite to the polarity of the position of the first movable part 420 close to the iron core. Therefore, it can push the first movable part 420 to move out of the extension port, thereby driving the support platform 200 to move and separate from the weighing module 700.

[0051] In some embodiments of the present invention, Figure 10 As shown, the electric-controlled displacement module 400 includes a motor drive component 440 and a second movable part 450 that can be driven by the motor drive component 440. The control module 500 is electrically connected to the motor drive component 440. The motor drive component 440 is arranged on the scale housing 100. The second movable part 450 is movably arranged on the scale housing 100. The movement of the second movable part 450 can drive the supporting platform 200 to contact or separate from the weighing module 700.

[0052] Specifically, the electric-controlled displacement module 400 also includes a second mounting seat 460 arranged in the scale housing 100, the motor drive assembly 440 is arranged in the second mounting seat 460, and the second mounting seat 460 is provided with an extension port that allows the second movable part 450 to move. The motor drive assembly 440 includes a motor and a screw. The control module 500 is electrically connected to the motor to control the operation of the motor. The motor is arranged on the scale housing 100 (specifically, it can be arranged in the second mounting seat 460), and the drive shaft of the motor is connected to the screw to drive the screw to rotate. The second movable part 450 is sleeved on the screw and connected to the screw through a threaded structure. A guide rail is provided on the scale housing 100 (specifically, the guide rail can be arranged in the second mounting seat 460, not shown in the figure, and the guide rail is used to limit the rotation of the second movable part 450). The second movable part 450 is arranged on the guide rail. Driven by the rotation of the motor, the second movable part 450 moves along the guide rail to drive the supporting platform 200 close to or away from the weighing module 700.

[0053] In addition, the electric-controlled displacement module 400 may also be composed of a cylinder and a push rod.

[0054] In some embodiments of the present invention, Figure 3 、 4 As shown in Figures 5 and 6, the weighing module 700 includes a weighing sensor assembly 710 and a weighing platform 720 arranged in the scale housing 100. The weighing platform 720 is arranged on the upper surface of the scale housing 100, and the supporting platform 200 is located above the weighing platform 720. An opening 110 is provided on the scale housing 100. The weighing platform 720 extends through the opening 110 to the inside of the scale housing 100 and contacts the weighing sensor assembly 710. The electric control switching device can drive the supporting platform 200 to contact or separate from the weighing platform 720.

[0055] Specifically, the electrically controlled switching device can lift up the load-bearing platform 200 so that the load-bearing platform 200 is separated from the weighing platform 720 and supported by the electrically controlled switching device, or it can move downward so that the load-bearing platform 200 is supported by the weighing platform 720. The gravity of the object placed on the load-bearing platform 200 can press against the weighing platform 720 and be transmitted to the weighing sensor assembly 710 by the weighing platform 720. The weighing sensor assembly 710 can be composed of a weighing sensor 711 and a weighing sensor bracket 712. The weighing sensor bracket 712 is arranged in the scale housing 100 to install and fix the weighing sensor 711.

[0056] In some embodiments of the present invention, Figure 6As shown, the weighing platform 720 protrudes from the upper surface of the scale housing 100, and the bottom of the supporting platform 200 is provided with a first slot 210 that allows the weighing platform 720 to enter and abut against. Since the supporting platform 200 can be separately provided with the electric control switching device, when the electric control switching device drives the supporting platform 200 to move downward, the weighing platform 720 can be inserted into the first slot 210, which can limit the position of the supporting platform 200 and the weighing platform 720, and the supporting platform 200 can be better pressed against the weighing platform 720, thereby improving the weighing accuracy.

[0057] It should be noted that, in some embodiments of the present invention, the weighing module 700 can be composed of a panel arranged above the scale housing 100 and a weighing sensor assembly 710. The supporting platform 200 and the objects thereon can enable the panel to press against the weighing sensor assembly 710 for weighing.

[0058] In some embodiments of the present invention, the electric-controlled switching device and the carrying platform 200 can be fixedly connected, or the electric-controlled switching device and the carrying platform 200 can be separately provided, and the user can change the type of the carrying platform 200 according to actual conditions.

[0059] like Figure 7 、 8 As shown, the driving end of the electric-controlled switching device can contact the supporting platform 200 to drive the supporting platform 200 to move. It should be noted that the driving end of the electric-controlled switching device can be the first movable part 420 or the second movable part 450. The supporting platform 200 is provided with a second slot 220 that allows the driving end of the electric-controlled switching device to enter and abut against it, so that the supporting platform 200 can be better lifted and the position of the supporting platform 200 can be limited.

[0060] Specifically, in the cutting state, the electrically-controlled switching device lifts up the supporting platform 200, and the weighing platform 720 is in a suspended and separated state relative to the first slot 210, and the weighing platform 720 has no contact with the supporting platform 200. In the weighing state, the driving end of the electrically-controlled switching device moves downward, and the weighing platform 720 enters the first slot 210, while the driving end of the electrically-controlled switching device is in a suspended and separated state relative to the second slot 220, making the weighing more accurate.

[0061] According to the weighing method of the second aspect of the present invention, the electronic scale disclosed in any of the above embodiments is applied, including driving the load-bearing platform to separate from the weighing module through the electric control switching device and driving the load-bearing platform to contact the weighing module for weighing through the electric control switching device.

[0062] The weighing method of the present invention can switch between cutting and weighing states by electronic control and is easy to use.

[0063] According to the weighing method of the third embodiment of the present invention, the electronic scale disclosed in any of the above embodiments is applied, such as Figure 12 As shown, it includes: a target weight acquisition step, acquiring the target weight information input in the input module 300; a weighing step, driving the carrier 200 to contact the weighing module 700 to weigh the actual weight information of the object to be weighed on the carrier 200 and output it; a judgment step, judging whether the actual weight information is consistent with the target weight information. If not, the carrier 200 is driven to separate from the weighing module 700 until the weighing step is entered after the weighing control instruction is received; wherein, the weighing step and the judgment step are looped until the actual weight information is consistent with the target weight information.

[0064] It should be noted that the target weight information can be a value or a range. When the user sets the target weight information, he can enter a value, and the control module 500 will then convert the value into a reserved range of ±. The user can also set the range value by himself. If the actual weight information is equal to the target weight information or the actual weight information is within the range of the target weight information, then the actual weight information can be considered to be consistent with the target weight information. The user can set the target weight information and then place the object on the carrier 200, and cut it when the carrier 200 is separated from the weighing module 700, or weigh it when the carrier 200 is in contact with the weighing module 700. If the weighing result indicates that the actual weight information of the object does not match the target weight information, it will automatically switch to the state where the carrier 200 is separated from the weighing module 700, so that the user can add or remove objects on the carrier 200, which is convenient to use.

[0065] In some embodiments of the present invention, between the step of obtaining the target weight and the weighing step, there is included: a selection step, selecting whether to enter the weighing step, if so, entering the weighing step, if not, entering the weighing step until a weighing control instruction is received; the electronic scale also includes a vibration sensor, which can detect the vibration of the carrier platform 200, and the vibration sensor is connected to the control module 500, wherein the weighing control instruction is input by the input module 300 or generated by the control module 500 based on the signal feedback from the vibration sensor.

[0066] like Figure 13 As shown, during the cutting process, the vibration sensor outputs a signal, and the peak value of the signal in the figure represents each cutting action. When no cutting action occurs for a period of time, the control module 500 can consider that the external cutting process has been completed, that is, generate a weighing control instruction, and then enter the weighing step.

[0067] Specifically, when using the device, the user first inputs the target weight information through the input module 300. The user can then select whether to directly enter the weighing step or to proceed with the cutting step first through the input module 300. If the weighing step is entered, the electronically controlled switching device controls the carrier 200 to contact the weighing module 700 for weighing and outputs the actual weight information of the object. If the actual weight information of the object does not meet the target weight information, the cutting step is entered.

[0068] If the user chooses to enter the cutting step, the user needs to cut the object on the carrier 200 first. After the cutting is completed, the user can operate the input module 300 to control the weighing step, or control the weighing step through the detection of the vibration sensor. Similarly, in the weighing step, the actual weight information of the object is output. If the actual weight information of the object does not meet the target weight information, it returns to the cutting step and the operation is repeated until the actual weight information meets the target weight information.

[0069] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
