[0022] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention. The following is a detailed description of the technical solutions provided by each embodiment of the present invention in conjunction with the drawings.

[0023] See also Figures 1 to 4 The utility model provides a smart gasket for wireless charging, comprising a gasket device 1 and a gasket through hole 2, wherein the gasket through hole 2 is arranged at the center of the gasket device 1, and the gasket device 1 is sleeved on the columnar structure through the gasket through hole 2;

[0024] The gasket device 1 includes a gasket housing body 101, a gasket sidewall support plate 102, a gasket internal partition 103, a data transmission unit 104, a wireless charging coil 105, a first-level mounting compartment 106, a second-level mounting compartment 107, a pressure sensor 108, a strain gauge carrier 109, and a controller 110;

[0025] A gasket side wall support plate 102 is installed at the bottom of the gasket housing body 101. The gasket side wall support plate 102 and the gasket side wall support plate 102 form a safe space for installing electrical components. A gasket internal partition 103 is provided inside the gasket housing body 101. A first-level installation compartment 106 and a second-level installation compartment 107 are provided between the gasket internal partition 103 and the gasket housing body 101.

[0026] The first installation compartment 106 is used to install the wireless charging coil 105 and the data transmission unit 104, and the wireless charging coil 105 is connected to the data transmission unit 104. The second installation compartment 107 is used to install the pressure sensor 108 and the controller 110.

[0027] A strain gauge carrier 109 is installed between the bottom of the gasket internal partition 103 and the side wall of the gasket side wall support plate 102.

[0028] Specifically, the wireless charging smart gasket provided by the present invention has an internal partition 103 comprising a horizontal plate and a straight plate, wherein the horizontal plate is connected to the straight plate, and an angle between the horizontal plate and the straight plate is 90 degrees.

[0029] Specifically, the wireless charging smart pad provided by the present invention has a through hole on the horizontal plate of the internal partition 103 of the pad for installing the data transmission unit 104. The data transmission unit 104 includes a Bluetooth data transmission unit, and the present invention transmits data via the Bluetooth data transmission unit.

[0030] Specifically, in the wireless charging smart gasket provided by the present invention, the strain gauge carrier 109 is located vertically directly below the first-layer installation compartment 106 and the second-layer installation compartment 107 .

[0031] This device collects pressure data by embedding strain gauges in the gasket. The strain gauges convert physical deformation into resistance. The gasket is then connected to a full-bridge circuit, which converts the resistance into a voltage. This voltage is then used to determine pressure changes on the gasket. To use, simply install the device on a bolt and pass the wireless charging transmitter over the gasket (≤ 20 cm). The smart gasket then charges, collects data, and transmits it.

[0032] This new device uses strain gauges embedded in gaskets to convert physical deformation into digital signals. Compared to existing solutions that use encoders to determine bolt looseness based on the angle of nut rotation, this solution eliminates mechanical structures, resulting in higher accuracy, greater stability, simpler maintenance, and lower costs. This new device utilizes wireless charging and low-power Bluetooth communication. Compared to existing solutions using batteries and wired communication, it offers lower costs, easier installation and maintenance, and greater reliability.

[0033] The intelligent gasket device of this utility model comprises a gasket housing, gasket sidewall support plates, gasket internal partitions, a data transmission unit, a wireless charging coil, two-layer mounting compartments, a pressure sensor, a strain gauge carrier, and a controller. The gasket through-hole is located in the center of the gasket device, allowing the gasket to be easily placed on a columnar structure.

[0034] The gasket is designed with two mounting compartments. The first compartment houses the wireless charging coil and data transmission unit, which are connected to enable wireless charging and data transmission. The second compartment is used to install the pressure sensor and controller, which are responsible for collecting and processing pressure data.

[0035] The strain gauge carrier is installed between the bottom of the gasket's internal bulkhead and the sidewall of the gasket's sidewall support plate, located directly below the two-tiered mounting compartment. Its operating principle is that the strain gauge embedded in the carrier converts physical deformation into a resistance value. This resistance is then connected to a full-bridge circuit to convert the resistance into a voltage, thereby determining pressure changes on the gasket.

[0036] In addition, the smart pad also has a wireless charging function, which is achieved through a wireless charging coil. You only need to pass the wireless charging transmitter over the pad (no more than 20cm away) to charge, which is very convenient.

[0037] In terms of data transmission, the gasket of the present invention wirelessly uploads the collected pressure data to other devices or systems through the Bluetooth data transmission unit in the data transmission unit, thereby realizing remote monitoring and data analysis.

[0038] In general, the wireless charging smart gasket of the utility model is not only stable and reasonable in structure, but also has many technical advantages such as high precision, high stability, low cost, easy maintenance, wireless transmission and low power consumption. It can stably collect pressure data of key parts of the equipment, and provide reliable data support for the operating status and performance evaluation of the equipment, thereby improving the efficiency and safety of industrial production.

[0039] The strain gauge of this utility model is a sensor that can convert physical deformation into resistance value. Its working principle is based on the metal resistance strain effect. That is, when the strain gauge is deformed by external force, the length and cross-sectional area of the internal metal conductor will change, resulting in a corresponding change in the resistance value.

[0040] To further convert resistance changes into voltage, a full-bridge circuit is used. This circuit consists of four resistors, typically one of which is a strain gauge. When the strain gauge resistance changes, a stable DC voltage source creates a potential difference across the bridge, resulting in a voltage change.

[0041] The full-bridge circuit is chosen for its high sensitivity, temperature compensation, good linearity, and robustness against interference. These advantages make it a popular converter for strain gauge measurements, accurately converting physical deformation into a measurable voltage signal.

[0042] The wireless charging efficiency of the smart pad of the utility model may be between 70% and 85% at a charging power of 5W, and the actual efficiency may vary depending on the specific design and usage environment.

[0043] In terms of wireless charging distance, charging can be performed by passing the wireless charging transmitter over the pad (≤20cm). The maximum effective distance of wireless charging is 12 cm. In order to obtain the best charging effect and efficiency, it is recommended to keep the transmitter as close to the wireless charging coil of the smart pad as possible in actual application, but not exceeding this maximum effective distance.

[0044] The adaptability of wireless charging smart pads in different environments;

[0045] High temperature environment will affect the performance of electronic components, accelerate equipment aging, and even cause safety hazards. In order to address this problem, the utility model selects high-temperature resistant electronic components and materials and designs an effective heat dissipation structure. The heat dissipation structure adopts a copper guide to contact the gasket shell body 101. The copper guide dissipates the heat of the gasket shell body 101 and introduces an overheating protection mechanism.

[0046] In a high humidity environment, the device faces the risk of corrosion and short circuit of electronic components. Therefore, moisture-proof and corrosion-resistant materials are used as the material of the gasket shell body 101, and a desiccant storage tank is set inside the gasket shell body 101, and desiccant is placed in the desiccant storage tank.

[0047] Electromagnetic interference may interfere with data transmission and affect wireless charging efficiency. To solve this problem, the present invention designs a shielding layer that is tightly attached to the inner wall of the gasket housing body 101, selects components and transmission protocols with strong anti-electromagnetic interference capabilities, and conducts electromagnetic compatibility testing.
