Description

Technical Field

[0001] This utility model relates to the technical field of heating and health care, specifically to a heating insole main unit structure with a built-in battery. Background Technology

[0002] In modern society, with the continuous improvement of people's living standards and the increasing pursuit of quality of life, heated health care products have gradually become an indispensable part of daily life. Among them, heated insoles, as a product that can provide warmth to the feet in cold environments, have been favored by a wide range of consumers. Especially in winter, the demand for heated insoles is very strong, whether for outdoor workers, people who spend long periods in cold environments, or people with weak constitutions who are prone to cold hands and feet.

[0003] However, there are many problems with the existing heated insoles on the market that urgently need to be solved. These problems have greatly affected the user experience and the safety and reliability of the products.

[0004] From the perspective of product structure and ease of use, most heated insoles use a design where a heating element is placed on a regular insole, and the control board and battery are externally mounted. This design has significant drawbacks. In actual use, users need to secure the powered main unit to their ankle by strapping or other means. On the one hand, this strapping method severely affects the overall aesthetics, especially when wearing tight pants or shoes that expose the ankle; the externally mounted main unit looks very conspicuous and ruins the overall look. On the other hand, the externally mounted main unit causes great inconvenience to the user's movement. During activities such as walking and running, the main unit is prone to shaking, shifting, and may even collide with other objects, affecting the user's experience and posing certain safety hazards, such as damage to the main unit's casing leading to the exposure of internal components.

[0005] While some heated insoles integrate the main unit into the heel, mitigating the aesthetic and mobility issues of external units to some extent, they suffer from serious deficiencies in safety design, particularly in explosion-proof and waterproofing. The heel is a high-pressure area for the foot, subjecting the main unit to significant stress during daily walking. These insoles lack effective explosion-proof measures; when the user walks, jumps, or experiences an impact, the internal battery and other components are easily squeezed or ruptured, damaging the product and potentially injuring the user's foot. Furthermore, their waterproofing is inadequate. The unique environment inside the shoe allows moisture to easily seep into the main unit due to sweat or water. This moisture can easily cause short circuits, rendering the product malfunction or even leading to electrical leakage and other serious safety issues, threatening the user's personal safety.

[0006] Regarding temperature control, most existing heated insoles on the market lack effective temperature detection and control mechanisms, and almost none are equipped with temperature detection probes. This results in heated insoles being unable to accurately adjust and control the heating temperature according to different ambient temperatures, easily leading to temperature runaway. For example, in low ambient temperatures, heated insoles may not reach a sufficient heating temperature to provide effective warmth to the user's feet; while in relatively high ambient temperatures or when the user's feet are sweating excessively, the heated insoles may maintain a high temperature, causing excessively high foot temperatures, which not only makes the user feel uncomfortable but also poses a risk of burns. Especially for people with highly sensitive skin, such as the elderly, children, and diabetic patients, whose ability to perceive temperature may be reduced, such heated insoles lacking temperature control are more likely to cause burns, posing a serious threat to the user's health.

[0007] From the perspective of market demand and industry development, as consumers' requirements for heated insoles become increasingly demanding, existing products can no longer meet market needs. Consumers not only expect heated insoles to provide stable and lasting warmth, but also have higher expectations for the products' safety, comfort, aesthetics, and convenience. Therefore, developing a heated insole main unit structure that is structurally sound, easy to use, highly safe, and capable of precise temperature control has become a crucial issue that urgently needs to be addressed in the field of heated health care technology. This is of great significance for promoting the upgrading of heated insole products, meeting consumer needs, and fostering the healthy development of the entire industry. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a heating insole main unit structure with a built-in battery, which solves the problems mentioned in the background art.

[0009] Technical solution

[0010] To achieve the above objectives, this utility model is implemented through the following technical solution: a main unit structure for a heated insole with a built-in battery, comprising a main unit and a heating pad; characterized in that: the main unit includes a lower shell and an upper cover; a main control board is provided at the front of the lower shell, and a support frame and a battery are arranged sequentially from bottom to top at the rear; the upper cover is matched and fixed to the upper part of the lower shell; two positioning pins are symmetrically fixed vertically at the front of the lower shell; two positioning through holes are symmetrically provided on the main control board, and the positioning pins match and are inserted into the positioning through holes; the support frame is n-shaped, with the opening facing upwards during installation, and the battery is fixed inside the support frame, surrounded by cushioning foam; an electrode plate is provided at the front of the battery, and the electrode plate is fixed to the main control board; both the lower shell and the upper cover have notches on one side of their front end, and after matching and installation, the two notches form a wire outlet; the heating pad is connected to a wire, and the other end of the wire enters the lower shell through the wire outlet and connects to the main control board; the heating pad is provided with several NTC probes.

[0011] Preferably, the main control board has a control button and a charging connector on the left and right sides of its front end, respectively.

[0012] Preferably, the lower shell has buttons for pressing the control key on the left and right sides of the front end, and a leak-proof silicone ring for matching the charging connector on the right side, and an indicator light in the middle.

[0013] Preferably, the lower shell has a notch that matches the support frame, and the support frame is fixed in the notch.

[0014] Preferably, the NTC probe is connected to a wire.

[0015] Preferably, the gaps in the main unit are sealed with resin after installation.

[0016] This utility model provides a heating insole main unit structure with a built-in battery, which has the following beneficial effects: 1. Compared to most existing heated insoles that have external control boards and batteries, requiring the power unit to be strapped to the ankle, this invention integrates the power unit into the heel, eliminating the need for additional strapping and greatly simplifying the usage process, making it convenient for users to wear and move around in daily life. At the same time, the built-in design avoids the impact of an external power unit on the overall aesthetics of the outfit, allowing users to enjoy warmth without worrying about appearance, thus satisfying users' aesthetic needs.

[0017] 2. Regarding explosion-proof features, the top cover and support frame of the main unit are made of stainless steel, possessing excellent strength and pressure resistance. This effectively withstands the pressure applied by feet, preventing the main unit from bursting when stepped on. Flexible, heat-resistant cushioning foam surrounding the battery absorbs external vibrations and impacts, preventing punctures or bursts when the battery is subjected to force. For waterproofing, buttons, charging connectors, and all seams are sealed with resin, effectively preventing water from entering the main unit and mitigating the risk of short circuits due to water ingress, providing comprehensive protection for user safety.

[0018] 3. Several NTC probes installed on the heating pad can accurately detect the temperature of the heating pad in real time and promptly feed the temperature signal back to the main control board. Based on the feedback signal, the main control board adjusts the heating state of the heating pad in real time, effectively avoiding temperature runaway caused by differences in ambient temperature. This prevents burns due to excessively high temperatures or insufficient warmth, providing users with a safe and comfortable experience. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: Please refer to Figures 1 to 6A heated insole main unit structure with a built-in battery includes a main unit and a heating pad. The heating pad generates heat when powered on to provide warmth to the feet. The main unit includes a lower shell 3 and an upper cover 4. The front part of the lower shell 3 has a main control board 5, which is the control core and undertakes important functions such as controlling heating, receiving feedback signals, and managing charging. The rear part, from bottom to top, has a support frame 6 and a battery 7. The battery 7 serves as the power source, providing energy support for the heating pad and the operation of the main control board 5. The upper cover 4 is matched and fixed to the upper part of the lower shell 3, forming a good sealing fit with the lower shell 3 to prevent external dust, moisture, etc. from entering the main unit and damaging the internal components. The front part of the lower shell 3 has two symmetrically vertically fixed positioning posts A 301. The main control board 5 has two symmetrically positioned through holes A 501. The positioning posts A 301 match and are inserted into the positioning through holes A 501, which can accurately achieve the positioning and installation of the main control board 5.

[0022] The support frame 6 is n-shaped, with the opening facing upwards during installation. The battery 7 is fixed inside the support frame 6, and a cushioning foam 8 is provided around it. The foam is made of flexible heat-resistant material. The flexibility of the foam gives it good cushioning performance, which can absorb external vibrations and impacts, reducing vibration damage to the battery 7 during use. The heat-resistant material can effectively isolate the heat generated by the heating pad and the heat from the external environment from the battery 7, preventing the battery 7 from experiencing performance degradation, shortened lifespan, or even safety accidents due to excessive temperature. Meanwhile, the cushioning foam 8 can also fill the gap between the battery 7 and the support frame 6 and the lower shell 3, further fixing the position of the battery 7 and enhancing its stability. In this embodiment, the cushioning foam is placed between the upper cover 4 and the battery 7, but this is not the only option; users can set it according to their needs. The battery 7 has an electrode plate 701 at the front, which is fixed on the main control board 5 to realize the transmission and control of electrical energy, ensuring that the heating pad can heat up stably. Both the lower shell 3 and the upper cover 4 have notches on one side of their front end. After matching and installation, the two notches form a wire outlet 10. The heating pad is connected to a wire, and the other end of the wire enters the lower shell 3 through the wire outlet 10 and connects to the main control board 5. The heating pad is equipped with several NTC probes. NTC probes are negative temperature coefficient thermistors, which have the characteristics of high sensitivity and fast response speed. The probe can detect the temperature of the heating pad in real time and feed the temperature signal back to the main control board 5. The main control board 5 adjusts and controls the heating state of the heating pad in real time according to the received temperature signal, avoiding excessively high or low temperatures of the heating pad due to differences in ambient temperature or other factors. This effectively prevents the risk of temperature runaway, ensures safety and comfort during use, and reduces the possibility of accidents such as burns. The NTC probe used in this invention is MF52-10K, and there is only one probe. The specific model, quantity, and installation position are not unique and users can choose freely.

[0023] The main control board 5 has a control button 502 and a charging connector 503 on the left and right sides of its front end, respectively. The control button 502 is used to receive user operation commands to control the heating status of the heated insole, such as turning it on or off. The charging connector 503 is used to connect to an external power source to charge the battery 7 and ensure the battery 7's battery life.

[0024] The lower shell 3 has buttons 504 for pressing the control key 502 on the left and right sides of its front end, and a leak-proof silicone ring 505 for matching the charging connector 503. An indicator light 506 is located in the middle and is connected to the main control board 5. The main control board 5 also has a contact point located directly behind the indicator light 506 to provide the indicator light 506 with the necessary power to display the working status. If it is lit, it means that the heating pad is working. The button 504 makes it convenient for users to press and operate the control key 502, improving the ease of operation. The leak-proof silicone ring 505 can enhance the sealing of the charging connector 503 and prevent moisture from entering the main unit.

[0025] The lower shell 3 has a notch that matches the support frame 6. The support frame 6 is fixed in the notch. This arrangement enhances the protection of the bottom and makes the structure more compact.

[0026] The NTC probe connecting wire has its outer end entering the lower shell 3 through the wire outlet 10 and connecting to the main control board 5. The length of the wire connecting the NTC probe is greater than the length of the wire connecting the heating pad to prevent the NTC probe from falling off the heating pad due to friction and pressure when the user walks. It also forms a current loop to ensure normal operation. In actual production, the two wires can be fixed together.

[0027] The various components of this invention are fixed by adhesive bonding. The component layout within the lower shell 3 ensures an orderly distribution of each element, avoiding mutual interference and facilitating subsequent assembly, repair, and maintenance. The upper cover 4 and support frame 6 are made of stainless steel, whose high strength can withstand the pressure applied by the feet, preventing the battery 7 from being squeezed or damaged due to excessive force. Combined with the properties of the cushioning foam 8, this effectively reduces the risk of puncture or explosion of the battery 7. After the main unit is installed, its gaps are sealed with resin. More specifically, after the main unit is assembled, resin is filled and sealed at internal gaps such as the gaps around the button 504 and charging connector 503, and then the upper cover 4 is closed and sealed, with its gaps also filled with resin. This effectively prevents the risk of water entering the main unit during wading and causing a short circuit, ensuring the safe and stable operation of the heated insole. The electrical wires need to have good conductivity and insulation to ensure stable and efficient power transmission, while avoiding safety issues such as leakage due to insulation damage. During actual installation, the wires should be fixed along the inner edge of the shoe's contour as much as possible to prevent wear and tear caused by foot movement and shoe compression during use, which could lead to a risk of electrical leakage. To prevent injury in the event of a leakage, the operating voltage of this invention is set to approximately 5V for safety. In this embodiment, the specific details of how the wires connect to the main control board 5 inside the main unit are not shown or described in detail; you can choose according to your needs.

[0028] First, before use, connect an external power source via the charging connector 503 at the front of the lower casing 3 of the main unit to charge the battery 7. After charging is complete, when the user is wearing shoes with their feet above the insole, press the button 504 at the front of the lower casing 3. The button 504 will press the control button 502 on the main control board 5, sending an activation command to the main control board 5. After receiving the command, the main control board 5 controls the battery 7 to supply power to the wires through the main control board 5. The electrical energy is transmitted to the heating pad through the wires, and the heating pad converts the electrical energy into heat energy, starting to generate heat and providing warmth to the feet. The heating pad used in this invention is a flexible thin-film heating pad, but this is not the only one.

[0029] During the heating process, several NTC probes on the heating pad monitor the temperature of the heating pad in real time and convert the detected temperature signal into an electrical signal, which is then fed back to the main control board 5. The main control board 5 analyzes and processes the received temperature signal and adjusts the heating state of the heating pad in real time according to the preset temperature range. When the temperature of the heating pad exceeds the preset maximum temperature threshold, the main control board 5 controls the battery 7 to reduce the power supply to the heating pad, thereby reducing the heating power of the heating pad and lowering the temperature. When the temperature of the heating pad is lower than the preset minimum temperature threshold, the main control board 5 controls the battery 7 to increase the power supply to the heating pad, thereby increasing the heating power of the heating pad and raising the temperature, ensuring that the temperature of the foot inside the shoe is always kept within a comfortable and safe range.

[0030] Working process: First, based on the actual condition of the shoe, a notch matching the main unit is made at the heel inside the shoe. An opening is also made at the back of the heel to ensure that the button 504 and charging connector 503 on the front of the main unit's lower shell 3 are exposed for easy user operation and charging. Next, the power cord is fixed along the edge of the shoe's inner contour. Then, the heating pad is smoothly fixed on the inner surface of the shoe. Finally, the insole is placed on the heating pad, completing the preparation work for installing the heated insole inside the shoe.

[0031] Using the compatible charger, connect the charger plug to the charging connector 503 on the front of the main unit's lower casing 3. The charger will then begin charging the battery 7. Once fully charged, it is ready for use. When the user needs to use the device, they should wear the pre-installed shoes and place their feet on the insoles. The user then presses the button 504 exposed on the back of the heel. Button 504 will press down on the control button 502 on the main control board 5, sending a command to the main control board 5 to activate the heating function. Upon receiving the command, the main control board 5 immediately sends a power signal to the battery 7. The battery 7 then transmits electrical energy to the connected wires via the main control board 5. The electrical energy is quickly transferred to the heating pads via the wires. Upon receiving the electrical energy, the heating pads rapidly convert it into heat, providing warmth to the user's feet.

[0032] During the heating process, several NTC probes on the surface of the heating pad are powered by the battery 7 through the main control board 5 and continuously monitor the real-time temperature of the heating pad. The detected temperature data is converted into electrical signals and fed back to the main control board 5 via wires. The control chip inside the main control board 5 analyzes and processes the received temperature signals and compares them with a preset temperature range, such as a comfortable temperature range of 38℃-45℃. If the detected temperature of the heating pad is higher than the preset maximum temperature threshold, such as 45℃, the main control board 5 immediately sends a command to the battery 7 to reduce the power supply. The battery 7 reduces the power supply to the heating pad, thus weakening the heating intensity and gradually lowering the temperature. If the detected temperature of the heating pad is lower than the preset minimum temperature threshold, such as 38℃, the main control board 5 sends a command to the battery 7 to increase the power supply. The battery 7 increases the power supply to the heating pad, increasing the heating intensity and gradually raising the temperature, thereby keeping the temperature of the heating pad within the preset comfortable and safe range.

[0033] When the user no longer needs to use the heated insole, pressing button 504 again sends a command to control key 502 to stop heating. Upon receiving the command, the main control board 5 immediately stops the battery 7 from supplying power to the power cord, and the heating pad loses its power supply and stops heating. If the user forgets to manually stop it, the heating pad will automatically stop heating when the battery 7 is depleted. Furthermore, if the main control board 5 detects an abnormality in the circuit (such as a short circuit or overload), it will automatically cut off the power supply circuit and stop heating to protect the product and the user's safety.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
