Description

Technical Field

[0001] The utility model relates to the technical field of wearable devices, and in particular to a self-adaptive intelligent heating glove. Background Art

[0002] At present, the heating gloves on the market are all connected to the heating plate through an ordinary button switch to form a complete set of electric control heating modules, and then the module is sewn into ordinary cotton gloves, and a certain appearance modification is made to form an electric heating glove product. This ordinary electric heating glove does not contain a sensing element and cannot monitor the temperature inside the glove in real time. When the user wears it, he needs to plug in the battery first, and then press and hold the switch to turn on the power. After the power is turned on, the heating wire will continue to work at maximum power until the user feels that the temperature is too high, and then press the switch to lower the gear to reduce the heating power, thereby realizing gear switching.

[0003] Existing ordinary electric heating gloves do not have integrated sensing elements or temperature sensors, and cannot monitor the temperature inside the gloves in real time, which may cause the temperature to be too high or too low, affecting the comfort and safety of the user. When wearing such electric heating gloves, users need to plug in the battery first, and then turn on the power by long pressing the switch. This operation method is relatively cumbersome and not convenient enough, which may affect the user experience. The heating wire of current electric heating gloves will continue to work at maximum power after the power is turned on, until the user feels that the temperature is too high, and then press the switch to reduce the gear to reduce the heating power. This method has the problem of inaccurate heating power control, which may lead to untimely or inaccurate temperature adjustment. In view of the problems existing in the existing solutions, it is necessary to propose a new glove heating solution. Utility Model Content

[0023] The specific implementation of the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model.

[0025] The terms “first”, “second”, “third”, etc. are merely used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0026] The terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal, vertical or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0027] In addition, the terms "roughly" and "basically" are intended to explain that the relevant content does not require absolute precision, but can have certain deviations. For example, "roughly equal" does not only mean absolute equality. Since it is difficult to achieve absolute "equality" in actual production and operation, there are generally certain deviations. Therefore, in addition to absolute equality, "roughly equal" also includes the above-mentioned situation with certain deviations. Taking this as an example, in other cases, unless otherwise specified, the terms "roughly" and "basically" have similar meanings to the above.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Please refer to Figure 1 This embodiment provides an adaptive intelligent heating glove, including a glove body, wherein the outer surface and the inner surface of the glove body are both provided with at least one temperature sensor; the temperature sensor 10 on the outer surface of the glove body and the temperature sensor on the inner surface of the glove body are connected to the same comparison module 50; the other end of the comparison module 50 is connected to the heating module 60, and the heating module 60 is triggered to start or shut down based on the output level of the comparison module 50.

[0030] In the embodiment of the utility model, the utility model scheme is provided with temperature sensors both inside and outside the glove. The temperature sensor on the outer surface of the glove is used to collect the ambient temperature, and the temperature sensor inside the glove is used to monitor the temperature perceived by the human body. By comparing the two temperatures, automatic heating is achieved in low temperature scenes, so that the user does not need to perform any operation in the low temperature environment.

[0031] Preferably, the glove body comprises flexible layers 20 on the outer surface and the inner surface, and a heat-conducting layer 30 embedded between the outer surface flexible layer 20 and the inner surface flexible layer 20 ; the heating module 60 is disposed in the heat-conducting layer 30 .

[0032] In an embodiment of the utility model, the glove body adopts a flexible layer 20 having an outer surface and an inner surface to ensure comfort and fit. This design can make the gloves more ergonomic and improve wearing comfort. A heat-conducting layer 30 is embedded between the outer surface flexible layer 20 and the inner surface flexible layer 20. The function of the heat-conducting layer 30 is to conduct the heat generated by the heating module 60 to ensure that the heat is evenly distributed inside the glove, thereby improving the heating effect and energy saving. The heating module 60 is arranged in the heat-conducting layer 30 to generate heat to heat the gloves. The heating module 60 can adopt a resistance heating wire, a heating sheet or other heating elements to adjust the heating temperature by controlling the current to realize the intelligent temperature control function. The technical solution of this intelligent heating glove has the following beneficial effects:

[0033] 1) Provide comfortable warmth: The heating module 60 generates heat inside the glove, which can effectively increase the temperature of the hand and provide a comfortable warmth effect, which is particularly suitable for outdoor activities or work scenes in cold environments.

[0034] 2) Energy saving and high efficiency: The design of the heat conducting layer 30 can ensure uniform heat conduction, reduce energy loss, improve heating efficiency, and thus save energy costs.

[0035] 3) Ergonomic design: The glove body adopts a flexible layer 20 design, which conforms to ergonomic principles, improves wearing comfort and flexibility, and allows users to use the gloves more comfortably and freely.

[0036] Preferably, the flexible layer 20 is made of any one of leather, cloth, and rubber, or a combination of multiple materials.

[0037] Preferably, the heat-conducting layer 30 is made of any one of silica gel, graphite sheet, polymer composite material, metal film, heat-conducting glue and heat-conducting cloth, or a combination of multiple materials.

[0038] Preferably, Figure 2The comparison module 50 includes a plurality of subtractors and a multi-stage trigger; the temperature sensor 10 on the outer surface of the glove body is connected to the first comparator, which is used to output the difference between the ambient temperature collected by the temperature sensor 10 on the outer surface of the glove body and the preset ambient temperature threshold; the temperature sensor on the inner surface of the glove body is connected to the first comparator, which is used to output the difference between the sensible temperature collected by the temperature sensor on the inner surface of the glove body and the preset sensible temperature threshold; the difference between the ambient temperature and the preset ambient temperature threshold is input into the first level trigger 503, which is used to output the first level high level signal when the difference between the ambient temperature and the preset ambient temperature threshold meets the triggering condition of the first level trigger 503; the difference between the sensible temperature and the preset sensible temperature threshold is input into the second level trigger 504, which is used to output the second level high level signal when the difference between the sensible temperature and the preset sensible temperature threshold meets the triggering condition of the second level trigger 504; the second level trigger 505 is used to output the corresponding high level signal between the first level high level signal and the second level high level signal.

[0039] In an embodiment of the utility model, in order to achieve the best automatic heating effect, in addition to judging the ambient temperature, it is also necessary to judge the hand temperature. When the ambient temperature is very low and the hand temperature is also very low, it is necessary to heat the gloves. When the ambient temperature is very high, even if the hand temperature is low, wearing gloves is not a warming requirement and there is no need to heat the hands. Therefore, in addition to comparing the ambient temperature with the preset ambient temperature, it is also necessary to compare the ambient temperature with the hand temperature, and realize the ideal heating scene recognition through double comparison. Based on this, the utility model proposes a two-level comparison circuit design, and first compares the electrical signal collected by each temperature sensor with the preset signal threshold through a subtractor. If the ambient temperature is lower than the preset ambient temperature and the body temperature is also lower than the preset body temperature, heating needs to be performed. Therefore, only when the output values ​​of the two subtractors are both negative, the corresponding trigger outputs a high-level signal, otherwise a low-level signal is output.

[0040] Based on this, the first-level trigger is a negative edge trigger, and the second-level trigger 505 is an RS trigger.

[0041] Furthermore, the outer surface and inner surface of the glove body are respectively equipped with temperature sensors for real-time monitoring of the temperature inside and outside the glove. The outer surface temperature sensor is connected to the first subtractor 501, and the inner surface temperature sensor is connected to the second subtractor 502, as well as the inverting input and non-inverting input of the trigger. The differential trigger receives the signals collected by the inner and outer surface temperature sensors. Through the operation of the subtractor, the internal and external temperature differences can be accurately controlled to ensure the balance and stability of the internal and external temperatures of the glove. Through the design of the subtractor and the trigger, the internal and external temperatures of the glove can be accurately monitored and controlled to avoid discomfort to the user caused by excessively high or low temperatures. When the signal collected by the temperature sensor exceeds the preset threshold, the comparison module 50 can generate a high-level signal in time to trigger the protection mechanism to avoid safety problems caused by overheating of the gloves. Accurate temperature control and protection functions can improve the comfort and safety of users in cold environments, making smart heated gloves an ideal choice for users in winter activities.

[0042] In the embodiment of the utility model, when the corresponding subtractor is running, the difference between the electrical signals corresponding to the collected temperatures is calculated, and the voltage value of the electrical signal corresponding to the preset temperature is continuously input by an analog signal. The voltage value of the collected electrical signal is calculated by the voltage value of the analog signal as the difference between the two temperatures. The higher the corresponding temperature, the higher the voltage value of the electrical signal.

[0043] Preferably, the output end of the differential trigger is connected to the heating module 60; the heating module 60 is started when the differential trigger outputs a high level; and the heating module 60 is turned off when the differential trigger outputs a low level.

[0044] In an embodiment of the utility model, the non-inverting input terminal is an input terminal of a differential trigger, which is used to receive an input signal. When the signal is input to the non-inverting input terminal, the amplifier will amplify and output the signal. The inverting input terminal is another input terminal of the differential trigger, which is also used to receive an input signal. Unlike the non-inverting input terminal, the signal received by the inverting input terminal will be inverted and output by the amplifier. The voltage output by the differential trigger is equal to the voltage of the non-inverting input terminal minus the voltage of the inverting input terminal, and then multiplied by the amplification factor. This operation mode enables the differential trigger to measure the difference between the two input signals and amplify this difference to the output terminal. In the smart heating gloves, the two input terminals of the differential trigger are respectively connected to the temperature sensors on the inner and outer surfaces. By measuring the difference between the inner and outer temperatures, more precise temperature control can be achieved. When the difference between the inner and outer temperatures is too large, the differential trigger will amplify this difference and output a corresponding control signal to adjust the power of the heating element to achieve the balance and stability of the inner and outer temperatures of the gloves. Such a design can effectively improve the temperature control performance and user experience of the smart heating gloves.

[0045] Preferably, the glove body is further provided with a battery module 40; the battery module 40 is encapsulated by insulating material and then sewn to the outer surface of the glove body.

[0046] In the embodiment of the utility model, in the intelligent heating gloves, in addition to the differential trigger for temperature control, the glove body is also provided with a battery module 40. The function of this battery module 40 is to provide power for the heating element to ensure that the gloves can be continuously heated and kept warm. The battery module 40 is usually composed of high-performance batteries such as lithium batteries, which can provide sufficient power to support the heating function of the gloves. In order to ensure the safety and stability of the battery module 40, it is encapsulated with insulating materials and sewn to the outer surface of the glove body. This design can effectively isolate the contact between the battery module and the external environment, prevent the battery from being subjected to external impact or damage, and at the same time, the use of insulating materials can also prevent safety problems such as short circuit or leakage of the battery module, ensuring the safety of the user when wearing the gloves.

[0047] Preferably, the battery module 40 is used to supply power to the heating module 60 and the temperature sensor; a first switch circuit is provided between the battery module 40 and the heating module 60 and the temperature sensor.

[0048] Preferably, the first switch circuit includes a switch trigger module; the switch trigger module is a Hall sensor, a gyroscope, an infrared sensor, a thin film pressure sensor or a capacitive touch sensor.

[0049] In the embodiment of the utility model, in addition to starting the heating of the gloves based on temperature comparison, the solution of the utility model also needs to ensure that the gloves are in use. If the gloves are in an idle device, it is meaningless to perform corresponding heating. For example, a Hall sensor is used to identify whether the gloves are worn. The Hall sensor uses the Hall effect to detect changes in the magnetic field. When a magnetic field passes through the Hall sensor, a voltage signal is generated. By measuring the magnitude of this signal, the strength and direction of the magnetic field can be determined. The Hall sensor is installed at a specific position of the glove (relative to the inner surface). When the gloves are worn, the magnetic field of the hand will affect the output signal of the sensor. By monitoring the change of this signal, it can be determined whether the gloves are worn. The voltage signal output by the Hall sensor is monitored in real time. When the gloves are worn, the magnetic field of the hand will cause the signal to change. According to the judgment result, it is determined that the first switch circuit is closed. The closed state of the corresponding switch circuit is no different from the traditional inductive switch, which will not be repeated here.

[0050] The gyroscope, infrared sensor, thin film pressure sensor and capacitive touch sensor are based on the same principle. Sensors are set at corresponding positions. The first switch circuit is turned on or off through the gyroscope switch or the infrared switch, so that each component is powered only when it is worn, avoiding power loss caused by heating when not in use.

[0051] Preferably, a second switch circuit is further provided between the battery module 40 and the heating module 60 and the temperature sensor power supply; the second switch circuit is a switch circuit that is manually triggered actively.

[0052] In the embodiment of the utility model, the user does not necessarily need intelligent heating at all times. In order to avoid the gloves being heated all the time against the user's wishes, the utility model is also provided with a second switch circuit. When the user himself does not want to perform adaptive heating of the gloves, the heating process can be manually turned off to further improve the user experience.

[0053] In another possible implementation, the second switch circuit is configured with a corresponding electronic regulator or microcontroller unit (MCU). Select a switch that can control the heating power adjustment, such as a knob switch, a button switch or a touch screen, and ensure that the switch can be connected to the electronic regulator or MCU. Connect the selected switch to the electronic regulator or MCU. Usually, the output signal of the switch will be connected to the input port of the electronic regulator or MCU to receive the control signal of the switch. Programming is performed in the electronic regulator or MCU to associate the signal of the switch with the adjustment of the heating power. According to the state of the switch (on or off), the regulator or MCU will adjust the size of the heating power accordingly. Change the heating power by operating the switch. When the switch state changes, the electronic regulator or MCU will adjust the heating power according to the preset logic, thereby realizing the change of the heating power. When the user feels that the automatic temperature heating cannot meet the needs or the user feels that the temperature given by the automatic gear is too high and needs to lower the gear, the solution of the utility model can be manually controlled through the second switch circuit to provide a more personalized user experience.

However, the embodiments of the utility model are not limited to the specific details in the above implementation modes.

To avoid unnecessary repetition, the embodiments of the utility model will not further describe various possible combinations.
