[0028] The present application provides a dining chair circuit and a dining chair assembly including the same. The dining chair circuit and the dining chair assembly including the same are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0029] Figure 1 FIG. 1 is a schematic diagram of the structure of an embodiment of a dining chair assembly 10 of the present application. Figure 1 As shown, the dining chair assembly 10 includes: a dining chair 11 and a dining chair circuit 20 provided in the present application. The dining chair 11 includes a seating portion 12 and support legs 13.

[0030] The seat portion 12 is used for children to sit. In some embodiments, the seat portion 12 includes a groove, and the groove has two openings. When the child is placed in the groove, the child's legs can extend from the two openings. The seat portion 12 includes a seat back 121. The seat back 121 is arranged on one side of the groove and is higher than the groove. The seat back 121 is used for children to lean on. The seat portion 12 also includes a dining table 122, which is arranged on a side of the groove relative to the seat back 121. The dining table 122 is parallel to the ground. The dining table 122 is used to place food or other items. In some embodiments, the dining table 122 can move horizontally along the groove. A pulley or track can be installed at the connection between the dining table 122 and the groove. When a child sits on the dining chair assembly 10, the dining table 122 can be operated to move toward the child, close to the child, and convenient for the child to eat. When the child needs to leave the dining chair assembly 10, the dining table 122 can be operated to move away from the child to make room for the child to leave the dining chair assembly 10.

[0031] The support legs 13 are used to support the seating portion 12. In some embodiments, the horizontal cross-section of the seating portion 12 is a quadrilateral, and the dining chair assembly 10 includes four support legs 13, which are respectively disposed at the four corners of the seating portion 12 to jointly support the seating portion 12.

In some embodiments, the height of the support legs 13 is adjustable, so that the height of the dining chair assembly 10 can be freely adjusted by the user to meet the height requirements of different scenarios, and the dining chair assembly 10 has a wider range of uses.

[0032] Figure 2 FIG. 2 is a circuit block diagram of an embodiment of a dining chair circuit 20 of the present application. Figure 1-2 The dining chair circuit 20 includes a weighing sensor 21 , a weighing trigger component 22 and a controller 23 .

[0033] The weighing sensor 21 is provided on the dining chair 11. The weighing sensor 21 is used to measure weight. The weighing sensor 21 can convert the weight signal into a measurable electrical signal output. In some embodiments, the weighing sensor 21 works based on the strain principle. The strain gauge is fixed on the elastic body, and when the elastic body is deformed by external force, the strain gauge will also deform accordingly. The resistance value of the strain gauge will change accordingly with the change of its external shape. Inside the weighing sensor 21, at least 4 strain gauges are connected to form a Wheatstone bridge. When the weighing sensor 21 is subjected to force, causing the resistance of the strain gauge to change, the bridge will lose balance, so that when the excitation voltage remains unchanged, the size of the output signal is proportional to the force on the weighing sensor 21.

[0034] In some embodiments, a weighing sensor 21 is provided at the bottom of each supporting leg 13. The weighing sensor 21 is installed inside the supporting leg 13 and does not affect the appearance of the dining chair 11. The weighing sensor 21 is provided at the bottom of the supporting leg 13, and can directly measure the pressure generated by the child sitting on the dining chair 11, which is convenient for measuring the weight of the dining chair 11 and the child.

[0035] In some embodiments, the weighing sensor 21 is disposed at the bottom of the seating portion 12 .

[0036] In some embodiments, the dining chair circuit 20 includes a plurality of weighing sensors 21. The plurality of weighing sensors 21 are all connected to the controller 23 and are located at the same horizontal plane. The plurality of weighing sensors 21 can measure signal changes at multiple positions and send them to the controller 23. The controller 23 integrates the signals of the plurality of weighing sensors 21 to determine the weight of the child, so that the weight can be measured more comprehensively with high measurement accuracy.

[0037] In some embodiments, the multiple weighing sensors 21 are evenly distributed around the seat portion 12 and are at equal horizontal distances from the center point of the seat portion 12. When a child sits on the seat portion 12, the multiple weighing sensors 21 can be evenly stressed, and the weight of different positions of the seat portion 12 can be measured more accurately, thereby improving the measurement accuracy.

[0038] Measuring the weight of a child by the dining chair assembly 10 is simple and convenient, and no professional child weighing equipment is required. The child is easy to fix in the dining chair assembly 10, and the safety factor is high.

[0039] The weighing trigger component 22 is provided on the dining chair 11 for operation by the user. The weighing trigger component 22 is used to trigger the weighing function of the dining chair component 10. The weighing trigger component 22 includes a sensing button or a touch button that can be operated by the user.

[0040] In some embodiments, the weighing trigger assembly 22 is disposed on the back of the chair back 121. In this way, when a child sits on the dining chair 11, the weighing trigger assembly 22 will not be blocked, making it easy for the user to operate the weighing trigger assembly 22.

[0041] The controller 23 includes a first port T1 and a second port T2. The first port T1 is connected to the weighing trigger component 22, and the second port T2 is connected to the weighing sensor 21. The controller 23 is used to determine the weight measured by the weighing sensor 21 when the weighing trigger component 22 is triggered by a user operation.

[0042] The controller 23 receives the signal of the weighing trigger component 22 through the first port T1. When the weighing trigger component 22 is triggered by the user's operation, the controller 23 receives the trigger instruction, obtains the electrical signal of the weighing sensor 21 through the second port T2, and determines the weight measured by the weighing sensor 21 according to the electrical signal of the weighing sensor 21. In some embodiments, the change in resistance of the weighing sensor 21 is proportional to the change in pressure it is subjected to. Based on the proportional relationship and the resistance of the weighing sensor 21, the controller 23 determines the pressure it is subjected to, and further determines the weight measured by the weighing sensor 21.

[0043] In some embodiments, the controller 23 is disposed below the seat portion 12. A circuit board is disposed below the seat portion 12. The controller 23 is disposed below the seat portion 12, and is easy to disassemble, repair, and replace.

[0044] In some embodiments, the dining chair circuit 20 includes: a weighing sensor 21, a weighing trigger component 22 and a controller 23. The weighing sensor 21 can measure weight. The weighing trigger component 22 is connected to the controller 23, and the controller 23 is connected to the weighing sensor 21, so that when the weighing trigger component 22 is triggered by the user's operation, the controller 23 determines the weight measured by the weighing sensor 21, so that the user can operate the weighing trigger component 22 as needed to select when and whether to weigh, thereby improving the user experience.

[0045] The dining chair circuit 20 also includes a power supply circuit for supplying power to the weighing sensor 21 , the weighing trigger component 22 and the controller 23 .

[0047] The dining chair circuit 20 also includes a voice broadcast circuit 24 electrically connected to the controller 23, which is used to broadcast the weight measured by the weighing sensor 21. The controller 23 is used to control the voice broadcast circuit 24 to broadcast the weight measured by the weighing sensor 21 when the weighing trigger component 22 is triggered. The voice broadcast circuit 24 includes a speaker or a buzzer for broadcasting voice. The voice broadcast circuit 24 can be set together with the controller 23 on the circuit board, or it can be set separately. After determining the weight measured by the weighing sensor 21, the controller 23 sends the weight information to the voice broadcast circuit 24, and the voice broadcast circuit 24 converts the weight information into a voice signal and broadcasts it. The voice broadcast circuit 24 can broadcast the weight measured by the weighing sensor 21, so that the user can know the weight more clearly, and the user experience is good.

[0048] In some embodiments, the dining chair circuit 20 also includes a display circuit 25 electrically connected to the controller 23, which is used to display the weight measured by the weighing sensor 21. The controller 23 is used to control the display circuit 25 to display the weight measured by the weighing sensor 21. The display circuit 25 includes a display screen for displaying pictures or text information. The display screen can be set on the outer surface of the chair back 121 or the seating part 12 for the convenience of the user. After determining the weight measured by the weighing sensor 21, the controller 23 sends the weight information to the display circuit 25, and the display circuit 25 converts the weight information into digital information and displays it on the display screen. The display circuit 25 can display the weight measured by the weighing sensor 21, so that the user can know the weight more clearly and the user experience is good.

[0049] In some embodiments, the dining chair circuit 20 also includes a wireless communication circuit 26, which is connected to the controller 23 and is used to communicate with an external terminal. After determining the weight measured by the weighing sensor 21, the controller 23 sends the weight information to the external terminal or other intelligent device through the wireless communication circuit 26. The other intelligent device can be any home appliance with networking function (with WiFi module). The external terminal or other intelligent device can upload the weight information to the cloud platform, and the cloud platform can match the weight information with the pre-stored child information, automatically generate the child's weight change curve, and facilitate the user to know the child's weight change. The cloud platform can also generate a more detailed weight report based on the weight information, such as whether the current weight is normal, whether the weight change is normal, whether it is higher or lower than the average level, and give weight recommendations. The cloud platform can send the weight report to the user, such as a mobile phone APP, so that the user can get more information. The wireless communication circuit 26 can be implemented by technologies such as WiFi, Bluetooth, infrared or RF radio frequency. The wireless communication circuit 26 can send weight information to the external terminal, making the use of weight information more abundant.

[0050] In some embodiments, the wireless communication circuit 26 is a Bluetooth module circuit. After determining the weight measured by the weighing sensor 21, the controller 23 sends the weight information to an external terminal or other smart device paired or bound via Bluetooth through the Bluetooth module circuit, or the weight information can be sent to the external terminal or other smart device via Bluetooth broadcast. The external terminal or other smart device transmits the weight information to the cloud platform. The cloud platform can analyze and record the weight information and send the results to the user according to the user's needs. The wireless communication circuit 26 is implemented by the Bluetooth module circuit, which is low in cost and high in security.

[0051] In some embodiments, the dining chair circuit 20 further includes a confirmation button 27 connected to the controller 23, and the controller 23 is used to control the wireless communication circuit 26 to send weight information when the confirmation button 27 is triggered. After receiving the instruction that the confirmation button 27 is triggered and determining the weight measured by the weighing sensor 21, the controller 23 sends the weight information to the external terminal through the wireless communication circuit 26. The confirmation button 27 allows the weight information to be sent through the wireless communication circuit 26 when the user confirms that the weighing is completed or needs to send the weight information, and the user's choice is high.

[0052] In some embodiments, the dining chair circuit 20 also includes a zeroing button 28, which is connected to the controller 23. The controller 23 is used to redetermine the weight measured by the weighing sensor 21 when the zeroing button 28 is triggered. Upon receiving an instruction that the zeroing button 28 is triggered, the controller 23 is used to clear the weight measured by the weighing sensor 21 and then redetermine the weight. The zeroing button 28 can be arranged side by side with the weighing trigger component 22 on the chair back 121 to facilitate user operation. Before the user places the child on the dining chair assembly 10, the zeroing button 28 can be triggered first, and then the child can be placed on the dining chair assembly 10 to measure the weight. The zeroing button 28 allows the user to calibrate the weight measured by the weighing sensor 21 to improve the measurement accuracy.

[0053] In some embodiments, the dining chair circuit 20 also includes a peel button 29, which is connected to the controller 23. The controller 23 is used to determine that the weight measured by the weighing sensor 21 is zero when the peel button 29 is triggered. When receiving the instruction that the peel button 29 is triggered, the controller 23 is used to determine that the weight currently measured by the weighing sensor 21 is zero. After the child sits on the dining chair assembly 10, the weighing sensor 21 starts counting from zero, thereby directly measuring the weight of the child. The peel button 29 can be arranged side by side with the weighing trigger assembly 22 on the chair back 121, which is convenient for the user to operate. Before the user places the child on the dining chair assembly 10, the peel button 29 can be triggered first, and then the child is placed on the dining chair assembly 10 to measure the weight. The peel button 29 allows the weight of the dining chair assembly 10 to be removed when measuring the weight, thereby directly obtaining the weight of the child sitting on the dining chair assembly 10, and the measurement is more direct.
