[0036] In related technologies, chairs play an important role in people's lives, work, and leisure. People spend most of their time working and studying in chairs. Prolonged sitting and lack of exercise can easily lead to weight gain and sub-health conditions. In order to enable people to monitor their weight data in real time, a chair with a simple structure and accurate measurement function is proposed.
[0037] Reference Figures 1 to 7According to an embodiment of the present invention, a chair with a weighing function includes a seat assembly 100, a leg assembly 200, a weighing assembly 300, and a circuit board. The leg assembly 200 is mounted on the bottom of the chair and has a connecting end. The weighing assembly 300 includes an elastic element 310 and a strain gauge 320. The elastic element 310 includes an inner ring 311, an outer ring 312, and an elastic portion 313. The outer ring 312 is sleeved on the outer periphery of the inner ring 311. One end of the elastic portion 313 is connected to the outer peripheral surface of the inner ring 311, and the other end of the elastic portion 313 is connected to the inner peripheral surface of the outer ring 312. The inner ring 311 is sleeved on the connecting end and connected to the connecting end. The outer ring 312 is connected to the seat assembly 100. The strain gauge 320 is disposed on the... The elastic part 313 and strain gauge 320 are used to collect the deformation signal of the elastic part 313. The circuit board is electrically connected to the strain gauge 320 and is used to convert the signal collected by the strain gauge 320 into weighing data. In this way, by connecting the inner ring 311 to the connecting end, on the one hand, it is convenient to assemble the weighing assembly 300 to simplify the structure of the seat. On the other hand, since the strain gauge 320 is installed on the elastic part 313, when the user weighs himself, the gravity on the seat assembly 100 is transmitted to the leg assembly 200 through the outer ring 312-spring part-inner ring 311. The deformation of the elastic part 313 is larger, which allows the strain gauge 320 to accurately measure the deformation of the elastic part 313 and ensure that the seat can accurately measure the user's weight.
[0038] Specifically, when a user is weighing themselves, they sit on the seat assembly 100 with their feet off the ground. The user's weight is applied to the elastic part 313 through the outer ring 312. Since the inner ring 311 is sleeved with the connecting end, the elastic part 313 can deform. On the one hand, this facilitates the assembly of the weighing assembly 300, simplifying the structure of the seat. On the other hand, since the strain gauge 320 is mounted on the elastic part 313, when the user is weighing themselves, the weight of the seat assembly 100 is transmitted to the chair leg assembly 200 through the outer ring 312-spring-inner ring 311. The deformation of the elastic part 313 is greater, allowing the strain gauge 320 to accurately measure the deformation of the elastic part 313, ensuring that the seat can accurately measure the user's weight.
[0039] It should be noted that the circuit board includes a main control module, a communication module, and a power supply. The main control module includes a control chip; signals collected by the weighing device are transmitted to the main control module, and the active module converts the deformation signals into weighing data. The communication module is used for communication between the seat and the user terminal, sending the weighing data to the user terminal. Preferably, the communication module includes a Bluetooth module, and the user terminal can be an electronic device such as a smartphone or tablet. The weighing data is sent to the user terminal through the communication module, and the user can view the weighing data on the terminal's application software. Furthermore, the power supply is used to power the weighing seat, and the power supply can be a polymer battery.
[0040] Reference Figure 5 , Figure 6 In some embodiments of this utility model, four elastic portions 313 are provided, and the four elastic portions 313 are arranged at intervals along the circumference of the inner ring 311. The strain gauges 320 correspond one-to-one with the elastic portions 313, which can reduce the error caused by the user's center of gravity not being in the center of the chair assembly and improve the measurement accuracy of the strain gauges 320.
[0041] Specifically, four elastic parts 313 are evenly spaced along the circumference of the inner ring 311, and four strain gauges 320 are correspondingly configured. When the user weighs the weight, the gravity borne by the outer ring 312 is transmitted to the inner ring 311 through the four elastic parts 313, which can reduce the error caused by the user's center of gravity not being in the center of the chair assembly and improve the measurement accuracy of the strain gauges 320.
[0042] Of course, in other specific embodiments, the elastic part 313 may be configured in two or three, etc., and there is no limitation here.
[0043] Reference Figure 5 , Figure 6 In some embodiments of this utility model, the seat with weighing function also includes fasteners. The outer ring 312 is provided with a through hole 301. The fastener passes through the through hole 301 and is threadedly connected to the seat assembly 100, so that the outer ring 312 and the seat assembly 100 are stably connected, which facilitates installation or disassembly, so as to facilitate inspection or maintenance of the seat.
[0044] Reference Figure 5 , Figure 6 In some embodiments of this utility model, a default hole 302 is defined between adjacent elastic parts 313. Along the circumference of the inner ring 311, the default hole 302 is staggered from the through hole 301, which can prevent the outer ring 312 from breaking, thereby improving the service life of the elastic element 310.
[0045] Specifically, along the circumference of the inner ring 311, the default hole 302 is located between two adjacent default holes 302, that is, the default hole 302 is close to the elastic part 313. The connection between the outer ring 312 and the elastic part 313 has high strength, which can prevent the outer ring 312 from breaking, thereby improving the service life of the elastic element 310.
[0046] Reference Figure 5 , Figure 6 In some embodiments of this utility model, the default hole 302 is a waist-shaped hole or a round hole, which can prevent the elastic part 313 from breaking, thereby improving the service life of the elastic element 310.
[0047] Specifically, in the radial direction of the inner ring 311, from the inner ring 311 to the outer ring 312, the width of the elastic part 313 first decreases and then increases. This ensures both the contact area between the elastic part 313 and the inner ring 311 and the contact area between the elastic part 313 and the outer ring 312, thereby increasing the connection strength of the elastic part 313, preventing breakage of the elastic part 313, and thus improving the service life of the elastic element 310.
[0048] It should be noted that the wires connected to the strain gauge 320 can be connected to the circuit board through the default hole 302, which facilitates the wiring of the strain gauge 320.
[0049] In some embodiments of this utility model, the inner ring 311 has a uniform wall thickness. In the circumferential direction of the inner ring 311, the wall thickness at each position of the inner ring 311 is the same, which can ensure that the inner ring 311 is subjected to uniform force.
[0050] In some embodiments of this utility model, the outer ring 312 has a uniform wall thickness. In the circumferential direction of the outer ring 312, the wall thickness at each position of the outer ring 312 is the same, which can ensure that the inner ring 311 is subjected to uniform force.
[0051] Reference Figure 7 In some embodiments of this utility model, along the axial direction of the inner ring 311, the minimum thickness of the elastic part 313 is H1, and the minimum thickness of the outer ring 312 is H2, satisfying: 0.25≤H1 / H2≤0.5. On the one hand, this ensures that the elastic part 313 has sufficient elasticity, and on the other hand, it ensures that the elastic part 313 recovers after deformation.
[0052] Specifically, if H1 / H2 is less than 0.25, the minimum thickness of the elastic part 313 is too small, and the elastic part 313 is prone to cracking after deformation, resulting in the elastic part 313 being unable to recover after deformation. If H1 / H2 is greater than 0.5, the minimum thickness of the elastic part 313 is too large, and when the user sits on the seat assembly 100, the elastic part 313 cannot generate a sufficiently large deformation, resulting in inaccurate measurement data from the strain gauge 320.
[0053] In some embodiments of this utility model, the inner ring 311, the outer ring 312, and the elastic part 313 are an integral structure, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds and thus reducing the production and manufacturing cost of the weighing component 300.
[0054] Specifically, the inner ring 311, outer ring 312, and elastic part 313 are integrally formed by die casting, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds and thus reducing the production and manufacturing cost of the weighing component 300.
[0055] As another implementation, the outer peripheral surface of the inner ring 311 and the inner peripheral surface of the outer ring 312 can both be connected to the corresponding end of the elastic part 313 by welding. The welding method includes, but is not limited to, resistance welding, laser welding or ultrasonic welding, and is not limited here.
[0056] Reference Figure 1 , Figure 2 In some embodiments of this utility model, the chair leg assembly 200 includes a chair leg body 210 and a gas spring 220. The fixed end of the gas spring 220 is connected to the chair leg body 210, and the connecting end is the movable end of the gas spring 220. This can increase the height of the chair seat assembly 100 to accommodate users of different heights and improve the versatility of the chair.
[0057] Specifically, the chair base 210 is in contact with the ground, and the movable end of the gas spring 220 can rise or fall, so that the seat assembly 100 can move up and down relative to the chair base 210. When the user is tall, the height of the seat assembly 100 can be raised by the gas spring 220, and when the user is short, the height of the seat assembly 100 can be lowered by the gas spring 220, so as to accommodate users of different heights and improve the versatility of the chair.
[0058] Reference Figure 1 , Figure 2 In some embodiments of this utility model, the chair base body 210 includes a support seat 211 and a plurality of support feet. One end of the support seat 211 is connected to the fixed end of the gas spring 220, and the other end of the support seat 211 is connected to the support feet. The plurality of support feet are spaced apart around the circumference of the support seat 211. When the user sits at approximately the center of the chair base assembly 100, the user's weight can be distributed relatively evenly on each support foot 212.
[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.
[0060] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
