[0002] With the fast pace of modern life, more and more people spend long hours sitting at their desks or in front of computers. This sedentary lifestyle has been confirmed by numerous studies to be linked to various health problems, including cardiovascular disease, obesity, and spinal disorders. Therefore, designing a cushion that can remind users to take breaks and engage in simple activities is a response to the growing health awareness of modern people. For example, patent document CN211483735U uses a pressure sensor to detect pressure and a vibrator to remind users of the dangers of prolonged sitting.
[0003] Generally, pressure sensors are designed to detect whether someone is sitting on a seat cushion, and their working principle is usually based on sensing changes in pressure on the cushion surface. A vibrator provides a vibration alert to the user sitting on the cushion. In the aforementioned patent literature, the pressure sensor and vibrator are in direct contact, and as the pressure sensor is subjected to prolonged vibration from the vibrator, it is prone to damage. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a seat cushion that avoids direct contact between the reminder device and the pressure sensor, thereby extending its service life.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A sedentary reminder cushion includes a cushion body, a pressure sensor, and a reminder device. The cushion body includes an inner core, which comprises:
[0007] The limiting area includes a flexible body and a limiting density body. The upper surface of the limiting density body is provided with a sensor slot and an alert slot.

Detailed Implementation
[0031] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0032] like Figures 1 to 3 As shown, the sedentary reminder cushion includes a cushion body 100, a pressure sensor 200, and a reminder device 300. The cushion body 100 includes an inner core 110, which comprises:
[0033] The limiting region 111 includes a flexible body 111a and a limiting density body 111b. The upper surface of the limiting density body 111b has a sensor groove 111b1 and an alert groove 111b2. The sensor groove 111b1 and the alert groove 111b2 are staggered. The pressure sensor 200 is disposed in the sensor groove 111b1, and the alert 300 is disposed in the alert groove 111b2. The flexible body 111a is disposed on the upper surface of the limiting density body 111b.
[0034] The limiting region 111 is adapted to the shape of the buttocks. The flexible body 111 of the limiting region 111 supports the user's buttocks. Since the flexible body 111 is made of flexible material, the pressure sensor 200 set in the sensor slot 111b1 can sense pressure changes through the flexible body 111, thereby determining whether the user has been sitting for a long time. When it is determined that the user has been sitting for a long time, the reminder 300 in the reminder slot 111b2 can remind and massage the user through the flexible body 111. Since the pressure sensor 200 and the reminder 300 are staggered on the upper surface of the limiting density body 111b, compared with the prior art where the pressure sensor and the reminder are in direct contact and arranged in a vertical direction, it effectively avoids the vibration generated by the reminder 300 directly acting on the pressure sensor 200, thus preventing damage to the pressure sensor 200.
[0035] like Figure 1 As shown, the flexible body 111a and the limiting density body 111b are arranged from top to bottom. The upper surface of the flexible body 111a is concave and contacts the user's buttocks. The lower surface of the flexible body 111a is connected to the limiting density body 111b. The flexible body 111a and the limiting density body 111b can be connected together by adhesive.
[0036] The flexible body 111a can be made of memory foam, and the limiting density body 111b can be made of high-density foam. High-density foam refers to a material with a density higher than that of ordinary foam. Its density range is usually between 0.4 g / cm3 and 0.9 g / cm3. It has the characteristics of structural stability and not being easily deformed. Therefore, the sensor slot 111b1 and the reminder slot 111b2 can be opened on it.
[0037] like Figure 2 As shown, the sensor slot 111b1 and the reminder slot 111b2 are staggered on the upper surface of the limiting density body 111b. Taking the sensor slot 111b1 and the reminder slot 111b2 as U-shaped examples:
[0038] The reminder slot 111b2 includes:
[0039] First U-shaped groove 111b21;
[0040] The second U-shaped groove 111b22 has a smaller size than the first U-shaped groove 111b21. The second U-shaped groove 111b22 is located inside the first U-shaped groove 111b21, and the opening of the second U-shaped groove 111b22 is opposite to the opening of the first U-shaped groove 111b21.
[0041] The reminder 300 can be a rotating roller or the like. When the reminder 300 is a roller, multiple rollers are respectively arranged in the first U-shaped groove 111b21 and the second U-shaped groove 111b22, and the multiple rollers are spaced apart. The rollers rotate around a laterally arranged axis, that is, the side of the roller in the circumferential direction corresponds to the user's buttocks. The power component, wiring harness, etc. that drives the roller to rotate can be arranged on the limiting density body 111b. The side of the roller in the circumferential direction can be provided with a flexible material, such as silicone.
[0042] It should be noted that the flexible body 111a located above the roller is relatively thin to prevent it from being too thick and causing the user's buttocks to not feel the rotating roller.
[0043] The rotating roller effectively reduces the force of vertical vibration compared to the up-and-down vibration of the reminder, thus preventing damage to the pressure sensor 200 caused by the up-and-down vibration. In addition to reminding the user of prolonged sitting, the rotating roller also massages the user's buttocks.
[0044] The sensor slot 111b1 includes:
[0045] Two third U-shaped grooves 111b11, the size of which is smaller than that of the first U-shaped groove 111b21, the opening of which is opposite to the opening of the second U-shaped groove 111b22, and the two sidewalls of which are respectively located inside the two third U-shaped grooves 111b11.
[0046] The pressure sensor 200 can be a piezoresistive pressure sensor or a thin-film pressure sensor. Because the pressure sensor 200 is relatively thin, the depth of the third U-shaped groove 111b11 accommodating the pressure sensor 200 is less than the depth of the reminder groove 111b2. The pressure sensor 200 can be wrapped with a flexible material and fixed within the sensor groove 111b1 with adhesive.
[0047] As can be seen from the above, the sensor slot 111b1 and the reminder slot 111b2 are U-shaped and are staggered on the upper surface of the limiting density body 111b. The distance between the reminder slot 111b2 and the sensor slot 111b1 is not less than 10mm. The reasonable use of space layout effectively avoids the vibration of the reminder 300 from affecting the normal use of the pressure sensor 200.
[0048] like Figure 1As shown, the limiting density body 111b has a hole 111b3 for housing a timer, horn, power supply, charging port, etc. The timer, horn, power supply, charging port, switch, and power components can be integrated on a single circuit board. The timer is used to time the pressure sensed by the pressure sensor 200. When the pressure sensed by the pressure sensor 200 exceeds a preset value, it is determined that the user is in a prolonged sitting state. At this time, the reminder 300 and horn can be activated to remind the user that they are in a prolonged sitting state. The reminder 300 reminds the user mechanically, and the horn reminds the user verbally. The switch is used to turn the reminder 300 and pressure sensor 200 on and off. The power supply provides power to the timer, reminder 300, etc. The charging port connects to an external line to charge the power supply. The charging port, horn, and switch are located on the outer surface of the limiting density body 111b.
[0049] The limiting area 111 also includes:
[0050] A fiber layer (not shown) is disposed on the upper surface of the flexible body 111a, and the lower surface of the flexible body 111a is connected to the limiting density body 111b.
[0051] The fiber layer can be made of bamboo charcoal fiber, which has antibacterial, deodorizing, moisture-wicking and perspiration-absorbing properties. The fiber layer and the flexible body 111a can be connected together by means of sewing, bonding or other methods.
[0052] refer to Figure 1 and Figure 3 The seat cushion body 100 further includes:
[0053] Encapsulation body 120, which is wrapped around the outside of the inner core 110.
[0054] The package 120 may be made of cotton or linen material and have a zipper, allowing the inner core 110 to be detachably placed inside the package 120 for easy cleaning after removal. It should be noted that the charging port, speaker, switch, control panel, etc., are exposed on the outside of the package 120.
[0055] refer to Figure 1 and Figure 3 The upper surface of the limiting area 111 can be an inclined surface, the height of the rear side of the limiting area 111 is higher than the height of the front side of the limiting area 111, and the inclination is 5°.
[0056] like Figure 1 and Figure 3 As shown, the inner core 110 further includes:
[0057] Edge region 112, the edge region 112 includes an edge density body 112a, the edge density body 112a is disposed at the edge of the limiting region 111, and the density of the edge density body 112a is less than the density of the limiting density body 111b.
[0058] The edge region 112 is disposed on a portion of the edge of the limiting region 111, corresponding to the user's back and left and right sides. The height of the edge region 112 may be higher than the height of the limiting region 111, serving as support for the user's back and hands. In this embodiment, the height of the edge region 112 is approximately 10 cm higher than the upper surface of the limiting region 111.
[0059] The edge region 112 and the limiting region 111 can be placed in different packages 120, and the two packages 120 can be connected together by splicing or other means.
[0060] In addition to reminding users that they have been sitting for a long time, the reminder device 300 can also massage the user's buttocks and legs. Therefore, the sitting reminder cushion has two modes: a sitting reminder mode and a relaxation and soothing mode. Users can select the appropriate mode according to their actual needs via remote control.
[0061] Sedentary reminder mode: In this mode, the pressure sensor 200 starts working after the power is turned on. When the set threshold is reached, the timer starts counting. For example, when the pressure sensor 200 detects that the user is away from the mat for less than 1 minute, the reminder 300 is activated. The reminder 300 massages and reminds the user from weak to strong until the user leaves the mat.
[0062] The timer has two functions: recording the user's single sitting time and calculating the user's total sitting time for the day. When a single sitting time reaches 30 minutes and 60 minutes, the power is activated and a speaker sounds, reminding the user of the prolonged sitting and explaining the dangers of sitting for too long. When a single sitting time reaches 30 minutes, 40 minutes, and 50 minutes, the reminder device 300 provides the user with a light massage. When 60 minutes have passed, the massage intensity gradually increases from a light massage until the user gets off the mat and moves around. The timer restarts if the user is off the mat for more than 1 minute. The timer also calculates the user's daily sitting time, resetting the data to zero at midnight each day.
[0063] After receiving the instruction, the reminder device 300 begins to massage the user's buttocks and thigh muscles to relax the muscles and promote blood circulation. At the same time, it forces the user to get up and move around when the user has been sitting for 60 minutes, thereby reducing the sedentary behavior.
[0064] The speaker uses an independent switch, allowing users to turn it on or off as needed, and set the number of voice broadcasts and the broadcast interval as required to avoid disturbing others' work or study in public places. The interval range is selectable from 0-30 minutes, and the number of voice broadcasts and the broadcast interval can be adjusted using the control panel or remote control. When the speaker is on, it will only broadcast after the user has been sitting for 30 minutes. It will also alert the user when they have been sitting for 30 minutes and 60 minutes, informing them of the dangers of prolonged sitting and suggesting appropriate physical activity. The speaker will also alert the user that they have completed the recommended physical activity after they have been away from the mat for more than 1 minute.
[0065] Relaxation and Soothing Mode: In this mode, only the reminder and control panel are active. Users can select this mode through the control panel and adjust the massage intensity, which is divided into light massage and medium massage.
[0066] The control panel includes seat mode selection, speaker switch, broadcast frequency setting, broadcast interval setting, single sitting time and total daily sitting time, and massage intensity of the massage device in relaxation mode, which users can adjust according to their actual needs.
[0067] In summary, the pressure sensor 200 and the reminder 300 are staggered on the upper surface of the limiting density body 111b. Compared with the prior art where the pressure sensor and the reminder are in direct contact and arranged in a vertical direction, this effectively avoids the vibration generated by the reminder 300 directly acting on the pressure sensor 200, thus preventing damage to the pressure sensor 200.
[0068] The embodiments described above are only used to illustrate the technical ideas and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. The scope of patent application of this utility model should not be limited by these embodiments. That is, any equivalent changes or modifications made in accordance with the spirit disclosed in this utility model still fall within the patent scope of this utility model.
