Technical Field

[0001] This utility model relates to the field of posture reminder technology, specifically to a blanket-shaped posture reminder device. Background Technology

[0002] Existing posture reminder devices mainly fall into the following categories: wearable, visual recognition, and smart cushions. Among them, smart cushions have the lowest cost but also the worst performance. For example, Chinese patent CN201420732103.2, entitled "A Posture Reminder Cushion," requires high-precision and high-cost pressure sensors to detect poor postures such as forward head tilting and shoulder tilting; otherwise, it is very easy to miss the detection.

[0003] Therefore, those skilled in the art urgently need to design a blanket-shaped posture reminder device that can achieve accurate detection while ensuring cost. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defects existing in the prior art and thus provide a blanket-shaped sitting posture reminder device.

[0007] Inside the first blanket-shaped housing placed on the desktop: several pressure sensors are arranged in a bracket pattern and connected to a single / double switching signal conditioning module;

[0008] The interior of the second blanket-shaped housing, located on the seat, is symmetrically divided into a region near the table, a region away from the table, a left region, and a right region. Several pressure sensors are arranged in a bracket shape at the edges of both the region near and away from the table. Several pressure sensors are also arranged in a bracket shape at the edges of the left and right regions. Furthermore, several pressure sensors are arranged in a wavy line containing three arcs near the center of the second blanket-shaped housing in both the left and right regions.

[0036] Example 1

[0037] like Figure 4 A blanket-shaped posture reminder device includes: a power module, several pressure sensors 1 and a reminder module, and also includes: a first blanket-shaped housing 3, a second blanket-shaped housing 2 and a single / double switching signal conditioning module;

[0038] The power supply module, the single / dual switching signal conditioning module, and several pressure sensors 1 are connected in sequence; the single / dual switching signal conditioning module and the reminder module are connected.

[0039] like Figure 1-3 A schematic diagram showing the layout of several pressure sensors 1;

[0040] Inside the first blanket-shaped housing 3 placed on the desktop: several pressure sensors 1 are arranged in a bracket shape and connected to a single / double switching signal conditioning module;

[0041] The interior of the second blanket-shaped housing 2, which is arranged on the seat, is centrally symmetrically divided into a region near the table, a region away from the table, a left region, and a right region. Several pressure sensors 1 are arranged in a bracket shape at the edges of the regions near the table and away from the table. Several pressure sensors 1 are also arranged in a bracket shape at the edges of the left and right regions. Several pressure sensors 1 are arranged in a wavy line containing three arcs near the center of the second blanket-shaped housing 2 in the left and right regions. Several pressure sensors 1 inside the second blanket-shaped housing 2 are connected to a single / double switching signal conditioning module.

[0042] Specifically:

[0043] like Figure 2-3 As shown, the pressure sensors 1 arranged in a wavy linear pattern inside the second blanket-shaped housing 2 have two specific layout options. One is a pair of pressure sensors 1 facing each other; the other is two pairs of pressure sensors 1 facing each other. The wavy pattern makes it easier for the user to compare and detect pressure sensors when the device is tilted, and also reduces the number of pressure sensors 1 required.

[0044] The single / dual switching signal conditioning module includes: a first signal conditioning module and a second signal conditioning module;

[0045] The first signal conditioning module is connected to all pressure sensors 1;

[0046] The second signal conditioning module is connected to the pressure sensor 1 inside the first blanket-shaped housing 3 and inside the second blanket-shaped housing, in the area near and away from the table area.

[0047] The first signal conditioning module and the second signal conditioning module are connected.

[0048] The first signal conditioning module uses a first pressure differential positioner;

[0049] The first differential pressure positioner is connected to all pressure sensors 1 and the power module.

[0050] The second signal conditioning module uses a second pressure differential positioner;

[0051] The second differential pressure positioner is connected to the pressure sensor 1 inside the first blanket-shaped housing 3, the pressure sensor 1 inside the second blanket-shaped housing near the table area, and the pressure sensor 1 away from the table area, as well as the power module.

[0052] The reminder module uses a first signal light and a second signal light;

[0053] The first signal light is connected to the first differential pressure positioner;

[0054] The second signal light is connected to the second differential pressure positioner.

[0055] Both the first blanket-shaped housing 3 and the second blanket-shaped housing 2 are provided with through holes, through which the power supply module's power cord is connected to an external power source.

[0056] It should be noted that existing intelligent cushion-type posture reminder devices are usually integrated devices. Because they need to meet the comfort requirements during use, they often use a mesh surface, which is difficult to clean and accumulates dust easily. Therefore, in this embodiment, the pressure sensor 1 arranged in the first blanket-shaped housing 3 is detachably connected to the first blanket-shaped housing 3. The pressure sensor 1 arranged in the second blanket-shaped housing 2 is also detachably connected to the second blanket-shaped housing 2. Adjacent pressure sensors 1 are fixedly connected by a flexible connecting rod.

[0057] When cleaning is required, the user only needs to remove the built-in pressure sensors 1; clean the first blanket-shaped housing 3 and the second blanket-shaped housing 2; because the flexible connecting rod has fixed the position between the pressure sensors 1, there is no possibility of position displacement when the first blanket-shaped housing 3 and the second blanket-shaped housing 2 are put back in.

[0058] In this embodiment, the power module is connected to an external power source, and each pressure sensor 1 requires only 5V, eliminating the risk of electric shock.

[0059] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
