Description

Technical Field

[0002] As people's demand for managing their body shape, weight, and health becomes increasingly high, electronic scales are widely used. The existing electronic scale testing procedures are cumbersome, making it inconvenient for people to monitor their weight for a long time. Standing on the scale all the time to ensure test accuracy is also very time-consuming. Especially when using a desktop electronic scale for weighing, in order to ensure accurate measurement results, the user should preferably stand upright. If the body leans forward or bends over significantly when weighing, the measurement results will be biased. However, in order to see the measurement results clearly when reading, the user will unconsciously lower their head or bend over. In order to see the reading clearly, the user may bend over significantly, which is not only inconvenient, but also affects the accuracy of the measurement results and is inconvenient to use.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] Please refer to Figures 1-6 The present invention provides a weight detection chair 100, which includes a chair leg 1, a weighable gas rod 2 fixed to one end of the chair leg 1, a chassis 3 fixed to an end of the weighable gas rod 2 away from the chair leg 1, and a seat 4 fixed to an end of the chassis 3 away from the weighable gas rod 2;

[0030] The weighable gas rod 2 includes a gas rod inner tube 21 fixed to the side of the chassis 3 away from the seat 4, a gas rod outer tube 22 sleeved on the gas rod inner tube 21 and forming a sliding connection, and a weighing sensor 23 sleeved on the end of the gas rod inner tube 21 away from the seat 4; the weighing sensor 23 is housed in and fixedly connected to the gas rod outer tube 22, and the gas rod outer tube 22 passes through and is fixedly connected to the chair leg 1. Since the weighing sensor 23 is set in the weighable gas rod 2, its measurement method is simple, and the weighable gas rod 2 is easy to replace and assemble.

[0031] Specifically, when a person sits on the seat 4, gravity is transferred to the chassis 3 through the seat 4, and then transferred to the gas rod inner tube 21 by the chassis 3. The gas rod inner tube 21 is subjected to force, causing the weighing sensor 23 to deform, thereby obtaining weight data.

[0032] In this embodiment, the gas rod inner tube 21 includes a piston rod body 211 received in the gas rod outer tube 22 and slidably connected to the gas rod outer tube 22, and an extension section 212 extending from the piston rod body 211 toward the chair leg 1, wherein the outer diameter of the extension section 212 is smaller than the outer diameter of the piston rod body 211;

[0033] The weighing sensor 23 includes a pressure-bearing part 231 sleeved on the extension section 212, a support part 232 spaced apart on the outer peripheral side of the pressure-bearing part 231, and a plurality of sensing parts 233 connecting the pressure-bearing part 231 and the support part 232; the extension section 212 passes through the pressure-bearing part 231 and makes the piston rod body 211 abut against the pressure-bearing part 231, and the pressure exerted on the pressure-bearing part 231 is transmitted to the plurality of sensing parts 233; the support part 232 is fixedly connected to the gas rod outer tube 22.

[0034] In this embodiment, the thickness of the sensing portion 233 is smaller than the thickness of the pressure-bearing portion 231 and the thickness of the supporting portion 232. Specifically, the thickness direction refers to the axial direction along the weighable gas rod 2.

[0035] In this embodiment, the weighable gas rod 2 also includes a PCB assembly 24, which is fixed to the end of the gas rod outer tube 22 away from the seat 4, and the end of the gas rod inner tube 21 close to the PCB assembly 24 is spaced apart from the PCB assembly 24, and the sensing part 233 is electrically connected to the PCB assembly 24.

[0036] The sensing unit 233 transmits the deformation information to the PCB assembly 24, which converts the deformation information into force data to complete the weight measurement. It should be noted that other methods of converting deformation information into weight measurement information are also feasible and are not limited to the PCB method.

[0037] In this embodiment, the PCB assembly 24 includes a PCB shell 241 fixed to an end of the gas rod outer tube 22 away from the seat 4 and a PCB board 242 fixed in the PCB shell 241 .

[0038] In this embodiment, the weighing sensor 23 further includes a flat cable 235 , one end of which is fixed to the sensing portion 233 and the other end of which is electrically connected to the PCB assembly 24 .

[0039] In this embodiment, a strain sensing element 234 is provided on the sensing portion 233 , and deformation data of the sensing portion 233 is collected by the strain sensing element 234 and transmitted to the PCB assembly 24 .

[0040] In this embodiment, the pressure-bearing portion 231 is annular, so that the load cell 23 is subjected to a more uniform force.

[0041] In this embodiment, the support portion 232 is annular, so that the load cell 23 is subjected to a more uniform force.

[0042] In this embodiment, the weighable gas rod 2 further includes a gasket 25 sleeved on the extension section 212 , and one end of the gasket 25 close to the chair leg 1 abuts against the weighing sensor 23 .

[0043] In this embodiment, the seat 4 includes a seat cushion 41 fixed to the end of the chassis 3 away from the chair legs 1 , and armrests 42 and a backrest 43 respectively fixed to the end of the seat cushion 41 away from the chassis 3 .

[0044] Specifically, when a person sits on the seat 4, gravity will be transmitted to the chassis 3 through the seat cushion 41, and then transmitted to the weighing gas rod 2 through the chassis 3; the gas rod inner tube 21 is subjected to force and transmits the force to the gasket 25, and the gasket 25 then transmits the force to the pressure part 231 of the weighing sensor 23, and the supporting part 232 of the weighing sensor 23 contacts the bottom of the gas rod outer tube 22. Because the thickness of the sensing part 233 of the weighing sensor 23 is thinner than the thickness of the force-bearing part 231 and the supporting part 232, the sensing part 233 will deform at this time, and the strain sensing element 234 attached to the sensing part 233 will sense the deformation and transmit the data to the PCB board 242 through the cable 235. The PCB board 242 converts the signal into force data in some way, and the weight measurement is completed. The person can read the measurement data through the APP or other methods.

In this way, the measurement method of the weight detection chair proposed in the present invention is simple and easy to operate, and the user can measure at any time as long as they sit on the chair; during the test, the user can sit stably on the chair, the weight is evenly distributed, and the measurement accuracy is high; assembly and subsequent maintenance are convenient, and the gas rod can be directly replaced.
