Description

Technical Field

[0001] This utility model relates to the field of human posture detection technology, specifically to a detection device based on ergonomics. Background Technology

[0002] Ergonomics (also known as human factors engineering or human factors science) focuses on the interaction between humans, machines, and the environment to optimize work efficiency, comfort, and safety. It involves designing work environments and tools to adapt to human physiological and psychological characteristics, thereby improving work efficiency and reducing work-related injuries. With the changing work styles in modern society, prolonged sitting for work or study has become the norm. Poor posture can lead to various health problems, such as cervical spondylosis, lumbar spondylosis, and myopia.

[0003] For example, Chinese patent application number CN202022934899.8 discloses a chair for preventing myopia and hunchback. The chair includes a seat, a backrest mounted upwards at the rear end of the top surface, legs mounted downwards at the four corners of the bottom surface, and two vertically arranged electric push rods symmetrically mounted on the side walls. The top of each electric push rod is rotatably connected to a damping rod. Each of the two damping rods has a detection plate positioned vertically above the seat, extending radially outwards from its opposite side. A distance sensor is mounted on the top surface of each detection plate, and a pressure sensor is embedded on the side near the backrest. A detachable warning device is also mounted on the top surface of either detection plate, and a programmable controller connected to the warning device, pressure sensor, distance sensor, and electric push rods is embedded on the side near the backrest. This invention solves the technical problem of how to make the chair promptly remind people of poor posture, and has the advantage of effectively preventing myopia and hunchback.

[0004] However, the above-mentioned patent requires the user's chest to rest against the detection plate to detect sitting posture. When the user is sitting at work or studying, their lower back may be suspended, which may lead to lumbar spine disease over time. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an ergonomic detection device to solve the problem that in the prior art, people need to rest their chest on the detection plate to detect their sitting posture. When sitting at work or studying, their waist may be in a suspended state, which may lead to lumbar spine problems over time.

[0006] This utility model is achieved through the following technical solution:

[0007] An ergonomically based detection device includes a mounting rod installed on a chair, a cushion provided on the mounting rod, a detection component for detecting the lumbar curve of a user installed inside the cushion, a slider slidably connected to the mounting rod, a mounting plate fixedly connected to the slider, the cushion fixedly connected to the mounting plate, and a locking component installed between the mounting rod and the slider, allowing the slider to be fixedly connected to the mounting rod under the action of the locking component.

[0008] Furthermore, the locking assembly includes a plug rod, the slider has a first through hole adapted to the plug rod, the plug rod is slidably connected in the first through hole, the mounting rod has a plurality of second through holes adapted to the plug rod, and the slider and the mounting rod are locked together, with one end of the plug rod inserted into the first through hole and the corresponding second through hole.

[0009] Furthermore, a tension spring is fitted onto the insertion rod, and the two ends of the tension spring are fixedly connected to the side walls of the insertion rod and the slider, respectively. When the tension spring is in a naturally extended state, one end of the insertion rod protrudes from the first through hole and is inserted into the second through hole.

[0010] Furthermore, a pull rope is fixedly connected to the cushion, and one end of the pull rope is fixedly connected to the end of the insertion rod.

[0011] Furthermore, the cushion has a hollow interior, a massage plate is rotatably connected to the mounting plate, multiple protrusions are fixedly connected to the massage plate, and a first drive assembly for driving the massage plate is installed inside the cushion.

[0012] Furthermore, the first drive assembly includes a motor fixedly connected to the mounting plate, and the output end of the motor is fixedly connected to the side wall of the massage plate.

[0013] Furthermore, all of the aforementioned bumps are spherical.

[0014] Furthermore, the massage plate is circular, and the plurality of protrusions are evenly distributed around the center of the massage plate.

[0015] Furthermore, an air supply pipe is connected to the cushion, and the end of the air supply pipe away from the cushion is connected to a second drive component.

[0016] Furthermore, the second driving component is a negative pressure pump, and the air delivery end of the negative pressure pump is connected to the second driving component.

[0017] The beneficial effects of this utility model are as follows:

[0018] This ergonomically based detection device allows the user to unlock and lock the cushion, enabling it to slide along the length of the mounting rod along the slider and mounting plate. Once the cushion reaches the set position, the locking assembly secures the slider to the mounting rod. The user leans against the cushion, applying varying pressure to multiple pressure sensors. These sensors transmit electrical signals to a controller, which analyzes the user's lumbar curve to determine their posture. When poor posture is detected, the controller sends an electrical signal to an alarm, prompting the user to correct their posture and prevent lumbar spine problems. The cushion also provides lumbar support, further contributing to the prevention of lumbar spine issues.

[0034] Please see Figure 1-7This utility model provides a technical solution: an ergonomic detection device, including a mounting rod 2 installed on a chair 1, a cushion 3 provided on the mounting rod 2, a detection component 4 for detecting the lumbar curve of the user installed inside the cushion 3, a slider 5 slidably connected to the mounting rod 2, a mounting plate 12 fixedly connected to the slider 5, the cushion 3 fixedly connected to the mounting plate 12, and a locking component 6 installed between the mounting rod 2 and the slider 5, so that the slider 5 can be fixedly connected to the mounting rod 2 under the action of the locking component 6.

[0035] This solution also includes a controller 20, which is electrically connected to an alarm 21. The detection component 4 includes multiple pressure sensors 22 arranged in a matrix on the cushion 3. All pressure sensors 22 are electrically connected to the controller 20. Mounting rods 2 on the pressure sensors 22 are fixedly connected to the backrest of the chair 1, extending along the height direction of the backrest. A slider 5 is slidably connected to the mounting rod 2 and can be fixedly connected to the mounting rod 2 under the action of a locking component 6. The cushion 3 is fixedly connected to the slider 5, allowing the cushion 3 to move along the length direction of the mounting rod 2 with the slider 5.

[0036] In use, the user unlocks the locking assembly 6, allowing the backrest 3 to slide along the length of the mounting rod 2 along with the slider 5 and the mounting plate 12. After the backrest 3 moves to the set position, the locking assembly 6 fixes the slider 5 to the mounting rod 2. The user leans against the backrest 3, applying varying pressure to the multiple pressure sensors 22. The pressure sensors 22 transmit electrical signals to the controller 20, which analyzes the user's lumbar curve to determine their posture. When the user's posture is incorrect, the controller 20 outputs an electrical signal to the alarm 21, which responds, reminding the user to maintain proper posture and prevent lumbar spine problems. The backrest 3 also provides lumbar support, further preventing lumbar spine issues.

[0037] The technical solution of this application is based on ergonomics. Multiple pressure sensors 22 transmit the collected data to a controller 20 for analysis and judgment of the user's posture. When the user's posture is incorrect, the controller 20 outputs an electrical signal to an alarm 21, which responds, reminding the user to correct their posture. Furthermore, the backrest 3 provides support for the user's lower back, thus preventing lumbar spine problems. This fully aligns with the design principles of ergonomics, adapting to human physiological and psychological characteristics to reduce work-related injuries. By fully utilizing ergonomic design concepts and combining them with a chair, the effect of reducing work-related injuries and preventing lumbar spine problems is achieved.

[0040] The locking assembly 6 can also use bolts to fix the slider 5 to the mounting rod 2, but the operation is more complicated than in this embodiment. Therefore, the slider 5 is fixed to the mounting rod 2 by inserting a rod 7.

[0041] In use, the user pulls the insert rod 7 out of the second through hole 9, so that the cushion 3 can slide along the length of the mounting rod 2 along with the slider 5 and the mounting plate 12. After the cushion 3 moves to the set position, the insert rod 7 is inserted into the first through hole 8 and the second through hole 9 to fix the slider 5 to the mounting rod 2.

[0042] In this embodiment: a tension spring 10 is sleeved on the insertion rod 7. The two ends of the tension spring 10 are fixedly connected to the side walls of the insertion rod 7 and the slider 5, respectively. When the tension spring 10 is in a naturally extended state, one end of the insertion rod 7 protrudes from the first through hole 8 and is inserted into the second through hole 9.

[0043] In this scheme: a tension spring 10 is sleeved on the insertion rod 7, and the two ends of the tension spring 10 are fixedly connected to the side walls of the insertion rod 7 and the slider 5 respectively. When the tension spring 10 is in a naturally extended state, one end of the insertion rod 7 protrudes out of the first through hole 8 and is inserted into the second through hole 9.

[0044] In use, the user pulls the insertion rod 7 out of the second through hole 9, the tension spring 10 is stretched, and the cushion 3 can slide along the length of the mounting rod 2 with the slider 5.
