Description

Technical Field

[0001] This invention belongs to the field of glove heating technology, specifically relating to an intelligent electric heating glove. Background Technology

[0002] Electric heated gloves, as an effective personal warming device, are widely used in cold environments such as motorcycle riding, outdoor work, and winter sports. Their basic principle is to arrange heating structures such as heating wires or heating plates within the glove's interlayer, generating heat through battery power to warm the hands.

[0003] However, due to temperature differences in different parts of the human hand, such as the fingers, especially the fingertips which are furthest from the heart and have relatively poor blood circulation, the fingers are most susceptible to frostbite in cold environments. Therefore, to maintain hand temperature, the fingers require more external heat than the palm. To address this, utility model patent CN223247648U discloses an intelligent electrically heated glove, including a glove body, a heating unit, a sensing unit, an intelligent controller, and a power supply. The heating unit is divided into finger heating areas, palm heating areas, and back-of-hand heating areas, and is equipped with a heating element. The sensing unit includes a fingertip sensing area and a palm sensing area, and is equipped with a temperature sensor. The intelligent controller divides the different heating areas of the heating unit into several heating levels based on the temperature of the fingertip sensing area, with different heating levels corresponding to different heating areas. Its structure is simple, highly practical, and can intelligently sense temperature and adjust the heating levels for zoned heating, making it suitable for various occasions such as outdoor sports and labor in winter.

[0004] The above solution can heat the fingers, palms, and backs of the hands separately according to the degree of cold, providing different amounts of heat to different parts, making it more practical. However, the above heated gloves still have at least the following shortcomings:

[0005] 1. It can only make rough, regional overall temperature adjustments, which is difficult to cope with the different temperature needs of different parts of the hand in complex environments.

[0006] 2. The linear heating wires that are close to each other in adjacent heating zones will generate heat superposition, causing abnormal overheating in the finger gap area and producing a burning sensation, while areas such as the back of the hand may not get warm enough.

[0007] 3. The gloves are heavy and clumsy, sacrificing hand dexterity and tactile sensitivity, making them unsuitable for scenarios requiring precise operation.

[0008] Therefore, there is an urgent need for a more comfortable heated glove to systematically solve the above problems. Summary of the Invention

[0009] The purpose of this invention is to provide an intelligent electric heating glove to partially alleviate or solve the above-mentioned problems and improve the comfort of using the heating glove.

[0010] To solve the aforementioned technical problems, the present invention specifically adopts the following technical solution:

[0011] A smart electrically heated glove includes a glove body, a heating layer, a sensing layer, and a control layer; the glove body includes a first area covering at least a portion of the palm, the front of the index finger, the front of the middle finger, the front of the ring finger, and the front of the little finger, a second area covering the back of the index finger, a third area covering the back of the middle finger, a fourth area covering the back of the ring finger, a fifth area covering the back of the little finger, a sixth area covering the thumb, and a seventh area covering at least a portion of the back of the hand.

[0012] The heating layer includes seven independent heating elements respectively disposed in the first region to the seventh region. Each heating element is provided with at least one U-shaped structure. At least one side of the U-shaped structure in the second region, the third region, the fourth region, and the fifth region protrudes outward to form a protrusion. The protrusions on two adjacent U-shaped structures are staggered.

[0013] The sensing layer includes at least five main sensors and two auxiliary sensors, both of which are temperature sensors; the at least five main sensors are respectively disposed in the second region, the third region, the fourth region, the fifth region, and the sixth region; the two auxiliary sensors are respectively disposed in the first region and the seventh region.

[0014] The control layer is located in the seventh region. The sensing layer and the heating element are electrically connected to the control layer. The control layer is configured to adjust the on / off state or heating power of the heating element based on the temperature data fed back by the sensing layer.

[0015] As an improvement, the heating layer and the sensing layer are disposed inside the glove body, with the sensing layer located between the heating layer and the inner side of the glove body, and the control layer disposed on the outer side of the glove body and located outside the glove body.

[0016] As an improvement, the sixth region extends to the first metacarpal bone region and the thenar eminence region on the back of the hand, and the seventh region covers the second to fifth metacarpal bone regions on the back of the hand.

[0017] As an improvement, the control layer includes a main control board and an adjustment component, which are disposed in the region corresponding to the third to fifth metacarpal bones. The distance between the control layer and the wrist-metacarpal joint is 10 mm to 30 mm, and the distance between the control layer and the finger-metacarpal joint is 10 mm to 30 mm.

[0018] As an improvement, the protrusion in the second region is located on the side closer to the third region, and the protrusion in the fifth region is located on the side closer to the fourth region. Both sides of the U-shaped structure of the third region and the fourth region are provided with protrusions.

[0019] As an improvement, the minimum spacing between two adjacent protrusions is 4mm-12mm.

[0020] As an improvement, when the glove is in its naturally flat state, the shortest distance between the protrusions of the fourth region and the fifth region is 4mm-6mm, and the shortest distance between the protrusions of the second region and the third region, and the shortest distance between the protrusions of the third region and the fourth region is 10mm-12mm.

[0021] As an improvement, the heating wire in the sixth region starts from the web of the thumb and passes sequentially through the first position of the fingertip, the first metacarpal bone, the second position of the fingertip, the junction of the back of the hand and the palm, the third position of the fingertip, and the thenar eminence, forming at least three U-shaped structures. The at least three U-shaped structures cooperate to form a wrapping structure that wraps around the thumb, wherein the first position, the second position, and the third position are located on different sides of the fingertip.

[0022] As an improvement, one end of the heating wire in the first region is located in the palm area, and the other end passes around the front of the index finger, the front of the middle finger, the front of the ring finger and the front of the little finger in sequence and returns to the palm area, forming a U-shaped structure on the front of the index finger, the front of the middle finger, the front of the ring finger and the front of the little finger respectively.

[0023] As an improvement, the glove body is also provided with a first magnetic interface, which is located on the side of the glove body near the thumb on the index finger and corresponds to the proximal phalanx of the index finger.

[0024] The principle and beneficial technical effects of this invention are as follows:

[0025] In cycling scenarios, the hands are exposed to the wind, and different parts of the hand are exposed to different wind conditions, resulting in significant temperature differences between different parts. For example, when a user places their index and middle fingers on the clutch, the perceived temperature difference between the index and middle fingers and the ring, little, and thumb can reach 8°C or even higher. In addition, due to different riding habits, some riders choose to place their index finger on the clutch, while others choose to place all their fingers except the thumb on the clutch, which also leads to different temperatures in different parts of the hand.

[0026] The existing technology (CN223247648U) is essentially still a non-differentiated zone heating (that is, three-level adjustment based on the temperature of the fingertips), which cannot meet the temperature differences under different vehicle speeds, different grip postures, etc. In view of the above situation, this application provides a zone surface heating solution with a complementary temperature compensation structure, which can provide a suitable temperature for various parts of the hand while ensuring user comfort.

[0027] First, this solution divides the glove into a temperature-sensitive area (the back of the fingers) and a normal area (including the palm, back of the hand, and front of the fingers). Independent heating paths and a relatively dense array of main sensors are arranged in the temperature-sensitive area, while a similar independent heating path and an auxiliary sensor are set up in the normal area. In other words, by finely monitoring and targeting the temperature of key areas, and simultaneously using basic temperature sensors to monitor the temperature of the normal areas (the larger, relatively stable main areas of the palm and back of the hand), a higher-precision temperature monitoring and control of the entire glove can be achieved without significantly increasing the complexity of the equipment.

[0028] Furthermore, during the bending and gripping process of a user's hand while cycling, the deformation area is mainly the fingers, as well as the first metacarpal bone and the thenar eminence below the base of the thumb. The deformation of the second to fifth metacarpal bone areas is extremely small compared to the deformation areas. This application will divide the high deformation area (first to sixth areas) and the low deformation area (seventh area) and separate them. The control layer will be set in the low deformation area, which can, to a certain extent, prevent the heating path in the low deformation area from moving when the high deformation area is active, thereby ensuring the stability of the control layer.

[0029] Furthermore, this application also provides a jigsaw-style coupling design with staggered protrusions, which can alleviate the heat accumulation caused by the heating wires being too close together during high-power heating conditions (where high heating power is often necessary in the event of rapid temperature loss), thus preventing localized overheating. Simultaneously, the U-shaped structure design allows the glove to be in a near-surface heating state, improving heating uniformity and further enhancing the user experience.

[0030] In summary, this solution divides the area into two zones based on temperature sensitivity and deformation, and strategically deploys temperature sensors of varying densities. This ensures sufficient flexibility for the user's hand in all areas without excessively increasing the complexity of the device, while maintaining a suitable temperature for each part.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0045] In this document, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; it can be a connection within two components.

[0046] In this article, "U-shaped structure" refers to a geometric layout that approximates the letter "U" formed by heating wires (or electric heating wires) in a specific heating area of ​​the glove through a specific wiring path; its core features include a bottom section and two roughly parallel side sections extending from both ends of the bottom section.

[0047] Example 1

[0048] See Figures 1-8 and Figure 10 This embodiment provides a heated glove with zoned heating, including a glove body and a heating layer disposed therein. The heating layer includes seven independent heating wires, each corresponding to an independent heating area, and its on / off state or heating power can be independently controlled by the control layer 10 as needed, thereby achieving refined and differentiated heating of seven different areas of the hand, which is especially suitable for dynamic usage scenarios such as cycling.

[0049] Specifically, the heated glove includes a glove body and a heating layer. The heating layer includes seven independent heating wires, each disposed in one of seven independent heating areas. Each heating area includes a first area 8a covering at least a portion of the palm, the front of the index finger, the front of the middle finger, the front of the ring finger, and the front of the little finger; a second area 2a covering the back of the index finger; a third area 3a covering the back of the middle finger; a fourth area 4a covering the back of the ring finger; a fifth area 5a covering the back of the little finger; a sixth area 6a covering the thumb; and a seventh area 7a covering at least a portion of the back of the hand. Here, "front" refers to the side of the fingertip, and "back" refers to the back of the hand or the back of the finger. Specifically, the first area 8a has a first heating wire 8, the second area 2a has a second heating wire 2, the third area 3a has a third heating wire 3, the fourth area 4a has a fourth heating wire 4, the fifth area 5a has a fifth heating wire 5, the sixth area 6a has a sixth heating wire 6, and the seventh area 7a has a seventh heating wire 7.

[0050] The first region 8a primarily heats the contact surface when gripping objects and the fingertips that are easily compressed. The second to fifth regions 5a target the backs of each finger; these areas have a large wind-facing area and dissipate heat quickly in scenarios such as cycling, and independent heating effectively addresses the different working conditions caused by changes in finger posture. The sixth region 6a covers the entire thumb, including the fingertip and the back of the finger; in some embodiments, the sixth region 6a also includes the part of the thumb connecting to the palm. This application achieves comprehensive and targeted thermal coverage of key parts of the hand by finely dividing the space according to wind conditions and changes in user hand posture, specifically for dynamic usage scenarios, especially cycling.

[0051] In some embodiments, the sixth region 6a extends to the region of the first metacarpal bone 14 and the thenar eminence region 13, ensuring that the base of the thumb and the connected palm muscles are also heated when performing complex manipulation movements; the seventh region 7a covers the regions of the second to fifth metacarpal bones 18 on the back of the hand (i.e., the second metacarpal bone 15, the third metacarpal bone 16, the fourth metacarpal bone 17, and the fifth metacarpal bone 18, see details). Figure 10 It can provide a large area of ​​uniform heating for the back of the hand.

[0052] In some embodiments, one end of the heating wire in the first region 8a is fixed to the palm region, and the other end sequentially wraps around the front of the index finger, middle finger, ring finger, and little finger before returning to the palm region. As it wraps around the front of each finger, the heating wire forms a U-shaped structure on the front of the index finger, middle finger, ring finger, and little finger, respectively. This allows a single heating wire to continuously cover the fingertips of multiple fingers, achieving a transformation from discrete "point" or "line" heating to continuous "surface" heating, resulting in more uniform heat distribution and higher thermal efficiency.

[0053] In some embodiments, the heating wires of the second region 2a, the third region 3a, the fourth region 4a, and the fifth region 5a originate from the end near the back of the hand, bypass the fingertips, and return to the end near the back of the hand, forming a U-shaped structure on the back of the index finger, middle finger, ring finger, and little finger, respectively. This increases the coverage area of ​​a single heating wire on the back of the fingers, effectively addressing the rapid heat dissipation requirements of the windward side.

[0054] In some embodiments, the heating wire of the seventh region 7a originates from the side near the wrist and bends at least once in sequence along a first direction (e.g., transverse), a second direction (e.g., longitudinal), a third direction, and a second direction, forming at least one U-shaped structure with an opening facing the first direction and / or the third direction, wherein the first direction and the third direction are opposite. This serpentine or wavy path allows for the formation of a large, uniform heat field in the metacarpal region of the back of the hand, achieving uniform and sufficient heating.

[0055] In some embodiments, the spacing between two adjacent regions or adjacent heating wires within the same region (e.g., between parallel segments of a U-shaped structure) is 8mm-12mm, that is, the spacing between two adjacent U-shaped structures or the two sides of the same U-shaped structure is 8mm-12mm. The spacing between heating wires in two adjacent regions refers to the spacing when the fingers are closed (see details). Figure 4 In d1), the spacing between adjacent heating wires within the same area refers to the distance between the two sides of the U-shaped structure (see details). Figure 4 (d2 in the middle), thereby preventing the heat from adjacent heat sources from superimposing when the fingers are together, thus preventing local overheating, and ensuring uniform heating.

[0056] In some embodiments, the spacing between the heating wires in the first region 8a, the second region 2a, the third region 3a, the fourth region 4a, the sixth region 6a, and the seventh region 7a is 10mm-12mm. This slightly larger spacing is suitable for areas with thicker muscles or tissues and stronger heat accumulation capabilities, such as the palm, main fingers, and back of the hand, to avoid a stuffy feeling. The spacing between the heating wires in the fifth region 5a is 8mm-10mm. Compared to other regions, a smaller spacing between the heating wires on the back of the little finger can enhance the heating effect on this cold-prone area (the little finger is located at the edge of the hand, is small in size, has relatively less blood supply, and is more prone to feeling cold).

[0057] In some embodiments, considering the flexible movement and complex wind-receiving surface of the thumb, the heating wire in the sixth region 6a is designed as a complex wrapping path. Specifically, the heating wire in the sixth region 6a starts from the web of the thumb and passes sequentially through the first position of the fingertip (e.g., the side of the finger), the first metacarpal bone 14, the second position of the fingertip (e.g., the pad of the finger), the junction of the back of the hand and the palm, the third position of the fingertip (e.g., the back of the finger), and the thenar eminence, forming at least three U-shaped structures. These at least three U-shaped structures cooperate to form a wrapping structure that wraps around the thumb. In other words, the first position, the second position, and the third position are located on different sides of the fingertip. The three U-shaped structures cooperate to form a three-dimensional heating network that wraps around the pad, back, side, and connected palm area of ​​the thumb, ensuring that the thumb can receive stable and uniform heating under various flexion, extension, abduction, and other manipulation actions, preventing user errors due to freezing of key operating parts (the thumb is the main operating part during cycling).

[0058] In some embodiments, the heated glove further includes a control layer 10 (such as a fabric layer or flexible circuit board with integrated control circuitry), with the seven heating wires respectively connected to the control layer 10. The control layer 10 can independently control the on / off state or heating power of each heating wire. In other words, the seven heating wires are independently connected to the control layer 10, which can receive user commands or sensor signals (not shown in the figure, such as a temperature sensor) to achieve independent on / off control of each heating wire or stepless / multi-level adjustment of the heating power. Users can flexibly customize the heat output of each area according to ambient temperature, personal comfort, or specific usage scenarios (such as increasing the heating of the back of the fingers while cycling and reducing the power when stationary), achieving personalized comfortable heating and energy consumption optimization.

[0059] In some embodiments, the control layer 10 includes a main control board and an adjustment component, which are disposed in the regions corresponding to the third metacarpal bone 16 to the fifth metacarpal bone 18. The distance between the control layer 10 and the carpal joint is 10 mm to 30 mm (preferably 20 mm), and the distance between the control layer 10 and the metacarpophalangeal joint is 10 mm to 30 mm (preferably 20 mm). In this application, the "carpal joint" refers to the movable joint connecting the base of the carpal bones and metacarpal bones in the human hand, i.e., the dividing joint between the wrist and the base of the palm; the "metacarpophalangeal joint" refers to the movable joint connecting the distal end of the metacarpal bone and the base of the proximal phalanx in the human hand, also known as the "phalangeal joint".

[0060] In some embodiments, the glove body comprises at least an inner lining 1 (skin-contacting layer) and a protective layer (outer layer, windproof, waterproof, and abrasion-resistant) from the inside out. The heating layer is disposed between the inner lining 1 and the protective layer. This structure ensures that the heat generated by the heating wire is effectively transferred to the hand, while protecting the heating wire from external abrasion, pressure, or moisture, thus improving the product's durability and safety. Alternatively, a heat insulation layer can be added between the heating layer and the outer layer to reduce heat loss.

[0061] In summary, this application provides a "intermittent surface heating" cycling heating solution with independent zone heating. First, based on the heat dissipation characteristics of the hand during cycling, this application precisely divides the heating area into seven independently controlled zones. This allows temperature-sensitive areas exposed to the wind (such as the backs of the fingers) to receive differentiated heat supply from ordinary areas (such as the palm and back of the hand), fundamentally improving the problem of uneven heating in different parts of the body. Furthermore, each finger has its own independent heating wire, which can be matched to the heat dissipation rate of different fingers when the user frequently changes hand posture, whether the fingers are open or closed, or at different tilt angles, thus achieving independent temperature control in multiple zones.

[0062] Furthermore, a U-shaped heating wire layout is adopted in key areas such as the fingers, expanding the coverage area of ​​a single heating wire and realizing the transformation from "line heating" to "area heating." This allows for more even heat distribution, improving thermal efficiency and user comfort. Simultaneously, gaps are used between the individual heating wires and between the U-shaped structures within the heating wires themselves. Specifically, by scientifically setting the spacing between heating wires in different areas (e.g., 8 mm - 12 mm), and using a smaller spacing (8 mm - 10 mm) for easily cooled edges such as the little finger, targeted heating is enhanced while ensuring adequate buffering between adjacent heat sources when the fingers are closed, significantly reducing the risk of localized overheating due to heat accumulation.

[0063] In addition, considering the complex movement of the thumb and its special wind-facing surface (the central control of a motorcycle is basically completed by the thumb, and during operation, the thumb will extend towards the center console to increase the wind-facing area of ​​the back of the thumb, the pad of the thumb, the first metacarpal bone 14, and the thenar eminence), this solution also provides a sixth area 6a heating path that wraps around the pad of the thumb, the back of the thumb, the first metacarpal bone 14, and the thenar eminence, ensuring that this area can receive stable heating under various operating actions.

[0064] Example 2

[0065] Unlike Embodiment 1, this embodiment provides an improved glove solution for high-speed movement scenarios (such as fast cycling), i.e., scenarios with extremely rapid heat dissipation. It includes the structure of Embodiment 1, and also includes a temperature compensation structure, namely the protrusion 11 mentioned later. In other words, the heated glove in this embodiment is actually a heated glove with an interlaced heating wire layout. Through a dynamically spaced temperature compensation structure, it meets the high heating demands of dynamic usage scenarios while avoiding the problem of harmful heat accumulation when the gloves are closed. It should be noted that the heating wire in this embodiment can also be a single wire, i.e., a single heating wire covering the entire glove.

[0066] Specifically, see Figures 1-8 and Figure 10 The glove body includes at least one temperature-sensitive area, which includes at least a second region 2a covering the back of the index finger, a third region 3a covering the back of the middle finger, a fourth region 4a covering the back of the ring finger, and a fifth region 5a covering the back of the little finger. Heating wires located in the temperature-sensitive area are bent along the finger extension direction on the backs of the index, middle, ring, and little fingers to form U-shaped structures. At least one side of the U-shaped structure protrudes outward to form at least one protrusion 11. The protrusions 11 on adjacent U-shaped structures are staggered, so that the projections of the protrusions 11 on adjacent U-shaped structures in the glove thickness direction do not overlap, thereby achieving heat source misalignment. In other words, at least one side segment of the U-shaped structure is not completely straight but protrudes outward. When viewed from the glove thickness direction (i.e., perpendicular to the back of the hand), the protrusions 11 on any two adjacent U-shaped structures do not overlap on the projection plane. For example, the protrusion 11 of the index finger and the protrusion 11 of the middle finger near the index finger are offset on the projection plane.

[0067] In some embodiments, the protrusion 11 is at least one of U-shape, V-shape or wavy shape, used to adjust the center position of the heat source and the local heating density.

[0068] In some embodiments, the protrusion 11 of the second region 2a is located on the side closer to the third region 3a, and the protrusion 11 of the fifth region 5a is located on the side closer to the fourth region 4a. Both sides of the U-shaped structures of the third region 3a and the fourth region 4a are provided with protrusions 11. That is, the index finger and little finger only have protrusions 11 on one side. Specifically, the protrusion 11 on the back of the index finger (second region 2a) is located on the side closer to the middle finger (third region 3a), and the protrusion 11 on the back of the little finger (fifth region 5a) is located on the side closer to the ring finger (fourth region 4a). The U-shaped structures on the backs of the middle finger (third region 3a) and the ring finger (fourth region 4a) in the middle are provided with protrusions 11 on both sides. By using a straighter heating wire path in high-heat-risk areas (the outer sides of the index and little fingers are easily exposed to strong winds and dissipate heat quickly), targeted and more intense heat compensation can be achieved in high-heat-risk areas without disrupting the overall staggered layout principle.

[0069] In some embodiments, the shortest distance between two adjacent protrusions 11 is 4mm-12mm. When the glove is naturally flat (without external force), the distance between the protrusions 11 in the fourth region 4a and the protrusions 11 in the fifth region 5a (i.e., the backs of the ring and little fingers) can be set to a relatively close 4mm-6mm (preferably 6mm); while the shortest distance between the protrusions 11 in the second region 2a and the third region 3a, and the shortest distance between the protrusions 11 in the third region 3a and the fourth region 4a, is 10mm-12mm (preferably 10mm), that is, the distance between the protrusions 11 on the backs of the index and middle fingers, and the middle and ring fingers, can be set to 10mm-12mm. This effectively adapts to the physiological characteristics of the little and ring fingers being close together when the user's hand is gripping the glove, allowing the distance between the protrusions 11 to dynamically increase to a safer range when gripping.

[0070] The heated gloves with the above structure, firstly, through the staggered design of the protrusions 11, when the fingers are closed, the areas of the protrusions 11 on adjacent fingers where the heat is most concentrated are spatially misaligned, thus eliminating the direct frontal superposition of heat fields from a physical layout perspective. This fundamentally solves the hidden danger of local overheating caused by heat accumulation in the finger gap area, significantly improving safety and comfort. Furthermore, the spacing of the protrusions 11, specifically designed for the little finger and ring finger, cleverly utilizes the physiological changes in the hand from open to closed. The gripping action does not bring the heat source closer; on the contrary, the structural design increases the effective spacing, achieving a smart overheat protection effect of "the tighter you grip, the safer it is." This is perfectly suited for core usage scenarios such as cycling. Furthermore, a straighter heating wire path is used on the outer sides of the index and little fingers (for example, this part does not have a protrusion 11). This allows for targeted and more intense heat compensation in high-heat-risk areas (the outer sides of the index and little fingers are easily exposed to strong winds and dissipate heat quickly) without disrupting the overall staggered layout principle. This effectively reduces the temperature gradient between the inner and outer sides of the fingers, ensuring uniform hand heating and overall warmth retention in harsh, wind-cold environments.

[0071] In summary, this solution combines zoned "surface heating" with an interleaved temperature compensation structure to form a dynamic, gap-fitting heating scheme, which is especially suitable for demanding scenarios such as motorcycle riding where the uniformity, safety, and dynamic adaptability of hand heating are extremely important.

[0072] Example 3

[0073] Unlike Embodiment 1 and Embodiment 2, the gloves in this embodiment also include a sensing layer 9. That is, based on the gloves in Embodiment 1 or 2, this solution also provides a heated glove with a temperature sensing layer 9.

[0074] Specifically, see Figures 1-10 The heated glove includes a glove body, a heating layer, and a sensing layer 9. The sensing layer 9 is disposed between the glove body and the heating layer. The sensing layer 9 includes at least five main sensors 901 and two auxiliary sensors 902. Both the main sensors 901 and the auxiliary sensors 902 are temperature sensors.

[0075] The glove body includes a first region 8a covering at least a portion of the palm, the front of the index finger, the front of the middle finger, the front of the ring finger, and the front of the little finger; a seventh region 7a covering at least a portion of the back of the hand; and a temperature-sensitive area. The temperature-sensitive area includes a second region 2a covering the back of the index finger, a third region 3a covering the back of the middle finger, a fourth region 4a covering the back of the ring finger, a fifth region 5a covering the back of the little finger, and a sixth region 6a covering the thumb. The first region 8a and the seventh region 7a are each equipped with an auxiliary sensor 902, while the second region 2a, the third region 3a, the fourth region 4a, the fifth region 5a, and the sixth region 6a are each equipped with at least one main sensor 901. By setting an auxiliary sensor 902 in the larger first region 8a and the seventh region 7a, and simultaneously setting at least one main sensor 901 in each of the temperature-sensitive areas, a "main + auxiliary" layout strategy is adopted, achieving a combination of focused monitoring of highly dynamic and high-risk areas and basic monitoring of large, stable areas.

[0076] In some embodiments, the second region 2a, the third region 3a, the fourth region 4a, and the fifth region 5a are each provided with three main sensors 901, and the sixth region 6a is provided with two main sensors 901. By configuring a larger number and denser distribution of main sensors 901 (e.g., three on each finger and two on the thumb) in temperature-sensitive areas (the backs of the fingers and thumbs, which have fast heat dissipation, large temperature fluctuations, and high thermal safety requirements), high-intensity and fine-grained temperature monitoring of key areas (the backs of the fingers and thumbs, which are windward areas in cycling scenarios, experience significant temperature changes) can be achieved.

[0077] In some embodiments, the main sensor 901 is disposed at the knuckle in the corresponding region. Disposing the main sensor 901 in the low-deformation region of the corresponding region, i.e., at the knuckle, can greatly reduce the problem of "hand discomfort", that is, reduce measurement errors, discomfort and potential damage to the sensor itself caused by pressure, and improve wearing comfort and long-term reliability of sensing data.

[0078] In some embodiments, the sensing layer 9 further includes a connector that forms a main passage path 904 in a seventh region 7a and extends from the main passage path 904 to form a first branch 905, a second branch 906, a third branch 907, a fourth branch 908, a fifth branch 909, and a sixth branch 910 in the first region 8a, the second region 2a, the third region 3a, the fourth region 4a, the fifth region 5a, and the sixth region 6a, respectively; the main sensor 901 is located on the second branch 906, the third branch 907, the fourth branch 908, and the fifth branch 909, respectively; and the auxiliary sensor 902 is located on the first branch 905 and the main passage path 904, respectively.

[0079] In some embodiments, at least one mounting area 903 is provided on each branch. Specifically, at least one mounting area 903 is provided on the first branch 905, the second branch 906, the third branch 907, the fourth branch 908, the fifth branch 909, and the sixth branch 910, respectively. The width of the mounting area 903 is greater than the width of other parts of the branch. The main sensor 901 and the auxiliary sensor 902 are respectively mounted on the mounting area 903 of the corresponding branch. This provides a stable and flat mounting base for the main sensor 901 and the auxiliary sensor 902, ensuring reliable electrical connection between the sensor and the connector, and preventing them from easily falling off when the glove is bent.

[0080] In some embodiments, the heated glove further includes a control layer 10 (refer to the control layer 10 in Embodiment 1). The main access path 904 is connected to the control layer 10. Detection data from all main sensors 901 and auxiliary sensors 902 can be fed back to the control layer 10 through a network of connectors. The control layer 10 thus obtains temperature information of key areas of the hand in real time.

[0081] In some embodiments, the auxiliary sensor 902 of the first region 8a is disposed in the palm (preferably the center of the palm). On the one hand, as the central position, this position can better represent the temperature of the palm body. On the other hand, the concave state here can make the user feel almost no foreign object in the palm while holding the handle.

[0082] In some embodiments, the temperature sensor is an NTC thermistor or a thermocouple sensor.

[0083] This solution places the sensing layer 9 between the glove body (lining 1) and the heating layer. The sensor can simultaneously sense the temperature from the skin side (reflecting the user's sensation) and the temperature from the heating layer side (reflecting the heating condition). This "sandwich" layout allows the control system to acquire more comprehensive data that more closely approximates the actual thermal equilibrium state, thereby achieving more accurate, timely, and human-feeling closed-loop temperature control, effectively avoiding the one-sidedness of unilateral sensing.

[0084] Furthermore, based on the physiological characteristics and temperature sensitivity differences of different areas of the hand, an innovative "primary-secondary" sensor differentiated layout strategy is adopted. In temperature-sensitive areas (backs of fingers and thumb) where heat dissipation is rapid, temperature fluctuations are large, and thermal safety requirements are high, a larger number of primary sensors 901 are configured and more densely distributed (e.g., three on the backs of each finger and two on the thumb) to achieve high-intensity, refined temperature monitoring of key areas. In the larger, relatively stable main areas of the palm and back of the hand (areas one and seven), one secondary sensor 902 is configured for basic, representative temperature monitoring. This layout achieves optimized monitoring of both global and local temperatures with the most economical number of sensors.

[0085] Furthermore, by placing the main sensor 901 in the low-deformation area of ​​the corresponding region, namely the knuckle, the problem of "hand discomfort" can be greatly reduced. This reduces measurement errors, discomfort, and potential damage to the sensor itself caused by pressure, thereby improving wearing comfort and the long-term reliability of sensing data.

[0086] Furthermore, a series path is provided through connectors, which form the main through path 904 in the seventh area 7a (back of the hand), extending from which to branch paths to each zone. Sensors are all installed on their respective branches, and each branch has a wider mounting area 903 for secure sensor mounting. This integrated, networked wiring design effectively avoids the problems of uneven glove thickness caused by the messy arrangement of multiple independent wires in traditional wiring.

[0087] In summary, this application provides a multi-sensor partitioned layout scheme with a sandwich design, which can improve the detection accuracy of heated gloves in key areas while ensuring user comfort.

[0088] Example 4

[0089] Based on the heated gloves in Examples 1 to 3, see Figures 1-10 This embodiment provides an intelligent electric heating glove that, through a partitioned surface heating scheme with a complementary temperature compensation structure, provides suitable temperatures for various parts of the hand while ensuring user comfort.

[0090] Specifically, it includes the glove body, heating layer, sensing layer 9, and control layer 10.

[0091] The glove body includes a first region 8a covering at least a portion of the palm, the front of the index finger, the front of the middle finger, the front of the ring finger, and the front of the little finger, a second region 2a covering the back of the index finger, a third region 3a covering the back of the middle finger, a fourth region 4a covering the back of the ring finger, a fifth region 5a covering the back of the little finger, a sixth region 6a covering the thumb, and a seventh region 7a covering at least a portion of the back of the hand.

[0092] The heating layer includes seven independent heating elements respectively disposed in the first region 8a to the seventh region 7a. Each heating element has at least one U-shaped structure. At least one side of the U-shaped structure in the second region 2a, the third region 3a, the fourth region 4a, and the fifth region 5a protrudes outward to form a protrusion 11, and the protrusions 11 on adjacent U-shaped structures are staggered. The heating element can be a heating wire or a heating film (e.g., carbon cloth, graphene heating film, carbon nanotube film, etc.) (preferably a heating wire). Therefore, in some embodiments, the heating element is also referred to as a heating wire.

[0093] The sensing layer 9 includes at least five main sensors 901 and two auxiliary sensors 902, both of which are temperature sensors. The at least five main sensors 901 are respectively disposed in the second region 2a, the third region 3a, the fourth region 4a, the fifth region 5a and the sixth region 6a. The two auxiliary sensors 902 are respectively disposed in the first region 8a and the seventh region 7a.

[0094] The control layer 10 is disposed in the seventh region 7a. The sensing layer 9 and the heating element are electrically connected to the control layer 10. The control layer 10 is configured to adjust the on / off state or heating power of the heating element based on the temperature data fed back by the sensing layer 9.

[0095] In some embodiments, the heating layer and the sensing layer 9 are disposed inside the glove body, with the sensing layer 9 located between the heating layer and the inner side of the glove body, and the control layer 10 is disposed on the outer side of the glove body, i.e., on the outer surface of the glove body. Specifically, the inner side of the glove body here refers to the lining, and the outer side of the glove body refers to the protective layer.

[0096] In some embodiments, the glove body is further provided with a first magnetic interface 12, which is located on the side of the glove body near the thumb on the index finger and corresponds to the proximal phalanx of the index finger. The first magnetic interface 12 can correspond to an external magnetic interface (e.g., a second magnetic interface pre-installed on a bicycle handlebar) to quickly connect to a power source.

[0097] In summary, this application provides a partitioned surface heating scheme with a complementary temperature compensation structure, which provides suitable temperatures for various parts of the hand while ensuring user comfort.

[0098] First, this solution divides the area into a temperature-sensitive zone and a normal zone. In the temperature-sensitive zone, independent heating paths and multiple main sensors 901 are arranged in a relatively dense manner. In the normal zone, independent heating paths and an auxiliary sensor 902 are also set up. In other words, by conducting high-intensity and precise temperature monitoring of the key area and making targeted adjustments to the key area, while using basic temperature sensors to monitor the temperature of the normal area (the main area of ​​the palm and back of the hand, which is larger and has a relatively stable temperature), a higher precision temperature monitoring and control of the entire glove can be achieved without increasing the complexity of the equipment.

[0099] Furthermore, during the bending and gripping process of the user's hand while cycling, the deformation area is mainly the fingers, as well as the first metacarpal bone 14 and the thenar eminence below the base of the thumb. The deformation of the second to fifth metacarpal bones 18 is extremely small compared to the deformation area. This application will divide the high deformation area (first to sixth areas 6a) and the low deformation area (seventh area 7a) and separate them. The control layer 10 is set in the low deformation area, which can, to a certain extent, prevent the heating path in the low deformation area from moving when the high deformation area is active, thereby ensuring the stability of the control layer 10.

[0100] Furthermore, this application also provides a jigsaw-style coupling design with staggered protrusions, which can alleviate the heat accumulation caused by the heating wires being too close together during high-power heating conditions (where high heating power is often necessary in the event of rapid temperature loss), thus preventing localized overheating. Simultaneously, the U-shaped structure design allows the glove to be in a near-surface heating state, improving heating uniformity and further enhancing the user experience.

[0101] In summary, this solution divides the space into zones based on both temperature sensitivity and deformation, and strategically deploys temperature sensors of varying densities. This ensures sufficient flexibility for the user's hand in all areas while maintaining appropriate temperatures across all parts of the device without unduly increasing equipment complexity.

Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
