Description

Technical Field

[0001] The utility model relates to the field of MEMS sensors, in particular to a wearable MEMS sensor. Background Art

[0002] A MEMS sensor is a micro-electro-mechanical system sensor. It uses micro-nano technology to integrate the sensor and the micro-electro-mechanical system together. It senses external physical quantities through the deformation or vibration of the micro-mechanical structure and converts them into electrical signals.

[0003] Most of the current diving equipment on the market lacks the functions of automatic diving depth detection and real-time prompt. It relies on divers to estimate the depth by feeling and experience. This method not only has limited accuracy, but also greatly increases the risk of misjudgment due to the uncontrollability of human factors. It may make divers approach dangerous depths unconsciously, thus threatening their lives. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides the following technical solutions:

One side of the L-shaped fixing plate is fixedly provided with an oxygen cylinder mounting plate. The upper surface of the top of the back box is provided with a mounting groove. Both sides of the inside of the mounting groove are provided with limiting grooves. A MEMS sensor is installed inside the mounting groove. Limiting strips are arranged on both sides of the MEMS sensor. The limiting strips are restricted by the limiting grooves. The lower surface of the top of the L-shaped fixing plate is fixedly provided with a connecting plate. Limiting strips are arranged on both sides of the connecting plate.

Detailed Embodiments

[0015] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0016] Please refer to Figures 1-4, the present utility model provides a technical solution: a wearable MEMS sensor, including a back box 10, an L-shaped fixing plate 20 is installed on one side of the back box 10, an oxygen cylinder mounting plate 21 is fixedly arranged on one side of the L-shaped fixing plate 20, an installation groove 22 is opened on the upper surface of the top of the back box 10, limiting grooves 23 are opened on both sides inside the installation groove 22, a MEMS sensor 24 is installed inside the installation groove 22, limiting strips 25 are arranged on both sides of the MEMS sensor 24, and the limiting strips 25 are restricted by the limiting grooves 23. A connecting plate 26 is fixedly arranged on the lower surface of the top of the L-shaped fixing plate 20. Limiting strips 25 are arranged on both sides of the connecting plate 26, and the connecting plate 26 is installed inside the installation groove 22; openings 27 are opened on both sides of the back box 10, a first rotating cylinder 28 is rotatably installed inside the openings 27, a fixing strap 29 is wound around the periphery of the first rotating cylinder 28, and an interlocking block 211 is arranged at one end of the fixing strap 29.

[0017] In this implementation scheme, the stable installation is provided by the back box 10 and the L-shaped fixing plate 20. The oxygen cylinder mounting plate 21 is installed on the side surface of the L-shaped fixing plate 20. The cooperation of the installation groove 22 and the limiting groove 23 ensures the precise installation and stable limitation of the MEMS sensor 24. Through the design of the limiting strip 25, the stability and safety of the sensor are enhanced. In addition, the setting of the connecting plate 26 strengthens the connection strength between the L-shaped fixing plate 20 and the back box 10. The introduction of the first rotating cylinder 28 and the fixing strap 29 provides a flexible wearing method for the user. Through the design of the interlocking block 211, the fastening and adjustment of wearing are realized, greatly improving the comfort and adaptability of wearing. A control motor is installed below the first rotating cylinder 28 to control the rotation of the first rotating cylinder 28. The control motor is electrically connected to the MEMS sensor 24. When the MEMS sensor 24 detects a certain depth of the diver's descent and the water pressure increases, the fixing strap 29 is tightened by rotating the first rotating cylinder 28 to remind the diver and prevent the diver from diving too deep and endangering life safety.

[0018] Specifically, a receiving groove 31 is opened on the top of the back box 10, a second rotating cylinder 30 is rotatably installed inside the receiving groove 31, a C-shaped buckle 32 is wound around the periphery of the second rotating cylinder 30, a C-shaped buckle 32 is arranged at one end of the fixing strap 29, and a fixing opening for fixing the C-shaped buckle 32 is opened at the bottom of the back box 10.

[0019] In this implementation scheme, through the receiving groove 31 opened on the top of the back box 10, the rotatably installed second rotating cylinder 30 cleverly winds the C-shaped buckle 32. The combination of the C-shaped buckle 32 and one end of the fixing strap 29, together with the fixing opening at the bottom of the back box 10, realizes the quick locking and release during the wearing process, greatly improving the convenience and safety of the wearing operation.

[0020] Specifically, one side of the back box 10 is arc-shaped, and a buffer strip 11 is arranged on one side of the back box 10.

[0021] In this embodiment, by adopting an arc-shaped design on one side of the back box 10, it conforms to the ergonomic principle, reduces the sense of oppression during wearing, and also improves the wearing comfort of the device. At the same time, a buffer strip 11 is added on the arc-shaped side of the back box 10, effectively alleviating the impact of external shocks on the internal sensors, protecting the MEMS sensor 24 from accidental damage, not only extending the service life of the device, but also ensuring the stability and reliability of the sensor in a complex environment.

[0022] Specifically, the upper part of the MEMS sensor 24 is designed in a U shape, the connecting plate 26 is arranged inside the U-shaped groove, a taking groove for convenient taking is opened on the inner side of the upper part of the MEMS sensor 24, and a gap is left between the bottom of the U shape opened by the MEMS sensor 24 and the bottom of the connecting plate 26.

[0023] In this embodiment, by adopting a U-shaped design for the upper part of the MEMS sensor 24 and restricting the connecting plate 26 to be arranged inside the U-shaped groove, the installation and disassembly of the sensor are made more convenient. At the same time, a taking groove is opened on the inner side of the U-shaped groove, providing a convenient taking position for the user, facilitating the quick and safe removal of the sensor for inspection or replacement when needed. In addition, the gap left between the U-shaped bottom of the MEMS sensor 24 and the bottom of the connecting plate 26 effectively avoids the interference problem during the installation process, ensuring the smooth and stable installation of the sensor.

[0024] The working principle and usage process of the present utility model are as follows: First, wear the back box 10 of the wearable MEMS sensor 24 on the back, pass the fixing strap 29 through the first rotating cylinder 28 and adjust it to the appropriate tightness, and fix it through the interlocking block 211. Subsequently, pull out the C-shaped buckle 32 from the receiving groove 31 at the top of the back box 10 and buckle it with the other end of the fixing strap 29 to ensure stable wearing. During work, the MEMS sensor 24 monitors the required data in real time. The user can easily access the sensor through the taking groove in the U-shaped design for necessary operations. After completion, unfasten the C-shaped buckle 32 and the fixing strap 29, and take off the back box 10. The whole process is simple and fast, ensuring the efficient use and convenient management of the sensor.

[0025] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it.
