[0030] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure 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 this disclosure. Based on the described embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0031] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as “comprising” or “including” mean that an element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects.

[0032] The terms "parallel," "perpendicular," and "identical" as used in this disclosure include the strictly defined meanings of "parallel," "perpendicular," and "identical," as well as terms such as "approximately parallel," "approximately perpendicular," and "approximately identical," which include a certain degree of error. Taking into account measurement and errors associated with the measurement of a specific quantity (i.e., limitations of the measurement system), they represent acceptable deviations for a specific value as determined by a person skilled in the art. In embodiments of this disclosure, "center" can include a strictly defined location at the geometric center as well as a location approximately at the center within a small area surrounding the geometric center. For example, "approximately" can mean within one or more standard deviations, or within 10% or 5% of the value.

[0033] At least one embodiment of this disclosure provides a writing instrument. The writing instrument includes a main body structure, a grip structure, and a heating component. The grip structure is disposed on the main body structure. The grip structure protrudes from the main body structure and surrounds an internal space, within which the heating component is disposed. The heating component is configured to heat the grip structure.

[0034] At least one embodiment of this disclosure provides a heated grip structure. The heated grip structure is configured to be fitted over a writing instrument. The heated grip structure includes a grip structure and a heating component. The grip structure surrounds an internal space, and the heating component is disposed within the internal space. The heating component is configured to heat the grip structure.

[0035] The writing instrument and heated grip structure provided in at least one embodiment of this disclosure reduce user fatigue and minimize the impact of ambient temperature on grip posture by incorporating a heating component within the internal space enclosed by the grip structure. While adding a heating component requires space, the internal space of the grip structure provides space for its installation. Furthermore, since the grip structure is the part held by the hand during writing, the center of gravity of the writing instrument can be located in this part, resulting in a better writing experience. Additionally, when the grip structure is configured to correct writing posture, it can also serve a posture-correcting function.

[0036] The writing instrument and heated grip structure are described below with reference to the accompanying drawings and through some embodiments.

[0037] Figure 1 This is a schematic diagram of the structure of a writing instrument provided in at least one embodiment of the present disclosure. Figures 2 to 4 for Figure 1 The diagram shows a cross-section of the writing instrument from different perspectives.

[0038] refer to Figures 1 to 3 This disclosure provides a writing instrument in at least one embodiment. The writing instrument includes a main body structure 100, a grip structure 200, and a heating component 300. The grip structure 200 is disposed on the main body structure 100. The grip structure 200 protrudes from the main body structure 100 and surrounds an internal space 201, within which the heating component 300 is disposed. The heating component 300 is configured to heat the grip structure 200.

[0039] The writing instrument provided in this embodiment reduces user fatigue and minimizes the impact of ambient temperature on grip posture by incorporating a heating component within the internal space surrounded by the grip structure. While adding the heating component requires space, the internal space of the grip structure provides space for its installation. Furthermore, since the grip structure is the part held by the hand during writing, the center of gravity of the writing instrument can be located in this part, resulting in a better writing experience.

[0040] Furthermore, when the grip structure is configured to correct writing posture, it can also serve to correct posture. When the grip structure is configured to support the user's hand (such as the web of the thumb), the user can use the grip structure to support their hand, which helps reduce fatigue caused by prolonged gripping.

[0041] Specifically, let's take the example of a grip structure configured to correct writing posture. During the use of a writing instrument, the grip structure configured to correct writing posture can help correct the user's grip. However, in colder environments, the user may be affected by the ambient temperature, causing their grip posture to deform, making it difficult to maintain a correct writing posture during prolonged writing and easily leading to fatigue. In the writing instrument provided in this embodiment, a heating component can heat the grip structure, thereby warming the user's hands when holding the writing instrument. Moreover, since the user holds the grip structure, the grip structure heated by the heating component can more efficiently warm the user's hands. This not only improves the user's writing experience and facilitates continuous writing, but also provides a better posture correction effect for the user, preventing the user's grip posture from deforming due to ambient temperature.

[0042] It should be noted that this disclosure is illustrated in the examples described below ( Figure 8 and Figure 9 The relevant descriptions elaborate on the use of the grip structure for posture correction and fatigue prevention, which will not be described in detail here.

[0043] refer to Figure 1 For example, the grip structure 200 is the structure that a user holds in their hand when writing with a writing instrument.

[0044] refer to Figures 1 to 3 For example, the surface of the grip structure 200 protrudes relative to the surface of the main structure 100. For example, the portion of the grip structure 200 that protrudes relative to the main structure 100 surrounds the interior space 201.

[0045] refer to Figures 1 to 3 For example, the heating element 300 may be entirely located within the interior space 201. Alternatively, the heating element may be partially located within the interior space and partially located outside the interior space, such as extending beyond the grip structure.

[0046] In some examples, the writing instrument includes a pen. For example, a pen may include a ballpoint pen, fountain pen, pencil, brush, highlighter, electronic pen, etc. This disclosure does not limit the type, shape, or purpose of the pen, and will not elaborate on these aspects here.

[0047] refer to Figure 1In some examples, the main structure 100 includes a first end 110 and a second end 120 positioned opposite each other, with the first end 110 configured for writing. On the virtual connection M between the first end 110 and the second end 120, the distance between the orthographic projection of the writing tool's center of gravity G and the first end 110 is a first distance D1, and the distance between the orthographic projection of the writing tool's center of gravity G and the second end 120 is a second distance D2. The first distance D1 is less than the second distance D2. Therefore, the center of gravity G of the writing tool, which includes the grip structure 200 and the heating component 300, is closer to the first end 110, meaning the center of gravity G of the writing tool is closer to the writing end. Since the grip structure is heavier than the main structure, the overall center of gravity of the writing tool can be located in the part containing the grip structure. This enhances writing stability, reduces the user's hand strain, and improves the writing experience.

[0048] For example, Figure 1 , Figure 2 and Figure 3 The illustration schematically shows that the center of gravity G of the writing instrument roughly coincides with the center of the grip structure 200. However, this disclosure is not limited to this; the center of gravity of the writing instrument may also not coincide with the center of the grip structure.

[0049] For example, the center of gravity of a writing instrument can be determined by methods such as suspension, support, and balance, which will not be described in detail here.

[0050] For example, the position of the writing instrument's center of gravity can be changed by adjusting the position of the grip structure relative to the main body structure. Alternatively, the position of the heating element within the internal space can be adjusted. Finally, the position of the writing instrument's center of gravity can be changed by adjusting the materials of the main body structure and the grip structure.

[0051] refer to Figure 1 In some examples, the ratio of the sum of the first distance D1 and the second distance D2 to the first distance D1 can be in the range of 2 to 4. For example, the ratio of the sum of the first distance D1 and the second distance D2 to the first distance D1 can be in the range of 2.5 to 3.5. For example, the ratio of the sum of the first distance D1 and the second distance D2 to the first distance D1 can be 3. Of course, the ratio of the sum of the first distance D1 and the second distance D2 to the first distance D1 can also be other values ​​in the range of 2 to 4, which will not be elaborated here.

[0052] For example, if the main structure is roughly a columnar structure extending from the first end to the second end, the sum of the first distance and the second distance can be basically the same as the axial dimension of the main structure.

[0053] Figure 5This is a schematic block diagram of a circuit board for a writing instrument provided as an example in at least one embodiment of the present disclosure.

[0054] refer to Figure 2 , Figure 3 and Figure 5 In some examples, the heating assembly 300 includes a battery 310 and a circuit board 320 electrically connected to each other, the circuit board 320 including a heating element 321. The battery 310 is configured to supply power to the circuit board 320, causing the heating element 321 to heat the grip structure 200. Thus, the grip structure 200 can be heated using the heating element 321 on the circuit board 320 to achieve a hand-warming effect for the user. Furthermore, the heating assembly 300 has a simple structure, which contributes to weight reduction in the writing instrument.

[0055] refer to Figure 2 and Figure 3 For example, battery 310 and circuit board 320 can be electrically connected by wires.

[0056] refer to Figure 3 In some examples, the main structure 100 includes a first end 110 and a second end 120 positioned opposite each other, with the first end 110 configured for writing. The length of the virtual connection M between the first end 110 and the second end 120 is a first dimension L1, and the orthographic projection of the center C of the battery 320 onto the virtual connection M and the connection to the first end 110 is a second dimension L2. The ratio of the first dimension L1 to the second dimension L2 can be in the range of 2 to 4.

[0057] Because of the simple structure of the heating component, the battery can account for a large proportion of the total weight of the heating component. Furthermore, when the battery has a regular shape, its center is easy to determine. By setting a range for the ratio of the first dimension to the second dimension, the center of gravity of the writing instrument can be easily determined from the position of the battery, which also simplifies the layout design of other structures within the writing instrument.

[0058] refer to Figure 3 For example, the ratio of the sum of the first dimension L1 and the second dimension L2 to the first dimension L1 can be in the range of 2 to 4. For example, the ratio of the sum of the first dimension L1 and the second dimension L2 to the first dimension L1 can be in the range of 2.5 to 3.5. For example, the ratio of the sum of the first dimension L1 and the second dimension L2 to the first dimension L1 can be 3. Of course, the ratio of the sum of the first dimension L1 and the second dimension L2 to the first dimension L1 can also be other values ​​in the range of 2 to 4, which will not be elaborated here.

[0059] For example, in conjunction with the examples above, Figure 3 The illustration shows that the center C of the battery 320 is substantially coincident with the center of gravity G of the writing instrument, thus... Figure 3 The second dimension L2 shown can be with Figure 1 The first distance D1 shown is essentially the same. However, this disclosure is not limited to this; for example, the center of the battery may not coincide with the center of gravity of the writing instrument.

[0060] For example, in conjunction with the examples above, Figure 3 The first dimension L1 shown can be with Figure 1 The sum of the first distance D1 and the second distance D2 shown is basically the same.

[0061] refer to Figure 3 For example, the battery 310 extends in the direction of the virtual connection M between the first end 110 and the second end 120. Thus, the battery 310 extends in the longitudinal direction of the main structure 100, which can make full use of the internal space 201, increase the battery capacity, extend the battery's battery life, and reduce the charging frequency.

[0062] Of course, this disclosure does not limit the shape of the battery. For example, the shape of the battery can be adapted to the internal space according to the battery capacity requirements. For example, the shape of the battery can include cylindrical, square, button-shaped, irregular shapes, etc.

[0063] refer to Figure 4 For example, the battery 310 and the circuit board 320 are stacked in a direction V perpendicular to the virtual connection M between the first end 110 and the second end 120. This allows for full utilization of the internal space 201 and also facilitates the routing of the wiring between the battery 310 and the circuit board 320.

[0064] refer to Figures 1 to 4 For example, the grip structure 200 may be provided with a charging port 240, through which the user can charge the battery 310.

[0065] refer to Figure 2 and Figure 3 For example, a bracket 400 is provided within the grip structure 200, and the battery 310 and circuit board 320 are mounted on the bracket 400. By providing the bracket 400, the battery 310 and circuit board 320 can be better secured. Moreover, the bracket 400 can adjust the relative position of the battery 310 and circuit board 320 to improve hand warming efficiency.

[0066] Specifically, referring to the example described later, when the hand is in a gripping position, the grip structure is closer to the thumb and the web of the hand than to other parts of the hand. By setting up a bracket, the heating element on the circuit board can be positioned closer to the thumb and the web of the hand within the internal space. Therefore, the thumb and the web of the hand can feel warmth more quickly.

[0067] refer to Figure 1In some examples, the grip structure 200 includes a raised structure 210 and a heat-conducting element 220, with the raised structure 210 surrounding the internal space 201. The heat-conducting element 220 covers at least a portion of the surface of the raised structure 210, and the heating element 321 of the circuit board 320 is configured to heat the heat-conducting element 220. Thus, the heat-conducting element 200 can be used to increase the heat-conducting area, and its excellent thermal conductivity can be used to accelerate heat transfer, more efficiently transferring heat to the user's hand and improving hand-warming efficiency.

[0068] For example, a heat-conducting component can cover the entire surface of the raised structure. Alternatively, a heat-conducting component can cover a portion of the surface of the raised structure while exposing another portion of the surface.

[0069] For example, the material of the heat-conducting component can include metallic materials. In some examples, the material of the heat-conducting component can include aluminum, zinc, iron, aluminum alloys, or zinc alloys.

[0070] For example, the heat-conducting element can be wrapped around the raised structure in a sheet-like form. For example, the heat-conducting element can be an aluminum sheet.

[0071] For example, the protruding structure can be made of non-metallic materials or metallic materials, and this disclosure does not limit it.

[0072] For example, in conjunction with the aforementioned example, the position of the circuit board in the internal space can be adjusted using a bracket, so that the heating element on the circuit board is closer to the heat-conducting component, thereby improving heating efficiency.

[0073] For example, the main structure can be made of a non-conductive material, and the protruding structure can also be made of a non-conductive material. However, this disclosure is not limited to this; the electrical parameters of the battery can be designed so that the user will not notice any difference during use. For example, the battery's output voltage can be 5V, and the maximum output current can be 1A.

[0074] refer to Figure 5 In some examples, the circuit board 320 also includes a temperature detection element 322 and a power-off protection element 323. The temperature detection element 322 is configured to detect the temperature of the heating element 321, and the power-off protection element 323 is configured to cut off the power to the circuit board 320 when the temperature of the heating element 321 reaches a threshold. By setting the temperature detection element 322 and the power-off protection element 323, the heating temperature of the heating element 321 can be effectively controlled, thus protecting the circuit board 320.

[0075] For example, the heating element's temperature can be controlled between 40 and 50 degrees Celsius. This effectively warms the hands while preventing the heating element's heat from affecting other components on the circuit board and ensuring smooth writing with the pen refill within the main structure.

[0076] For example, the heating element may include a heating wire. For example, the temperature sensing element may include a thermocouple. For example, the power failure protection element may include a thermistor.

[0077] refer to Figure 2 and Figure 3 In some examples, the writing instrument also includes a switch structure 500 electrically connected to the circuit board 320 to control the connection between the circuit board 320 and the battery 310. By setting the switch structure 500, the user can switch the heating component 300 between a heating state and an off state as needed.

[0078] refer to Figure 2 and Figure 3 In some examples, the grip structure 200 includes an opening 301 communicating with the internal space 201, and at least a portion of the switch structure 500 is located in the internal space 201 and exposed through the opening 301. Thus, the user can more easily control the power supply to or off of the circuit board 320 and the battery 310 using the switch structure 500 exposed through the opening 301.

[0079] However, this disclosure is not limited to this. For example, the writing instrument may be a push-button pen, and the main body may be equipped with a button (as described below) for controlling the extension and retraction of the pen tip, and a switch structure may be linked to the button on the main body. For example, when the user presses the button to extend the pen tip for writing, the circuit board and battery are simultaneously powered on, causing the heating element to start heating. For example, when the user presses the button to retract the pen tip to end writing, the circuit board and battery are simultaneously de-powered, causing the heating element to stop heating.

[0080] For example, refer to Figure 2 For example, the writing instrument may include a pen refill 601, and the second end of the main body structure 100 may be provided with a rotating wheel 602, a push-button 603, and a cap 604. The rotating wheel 602 may be located at the end of the pen refill 601 away from the pen tip, the push-button 603 may be sleeved on the rotating wheel 602, and the cap 604 may be sleeved on the push-button 603. For example, the pen tip of the pen refill 601 may be fitted with a spring 605. Thus, the rotating wheel 602, the push-button 603, the cap 604, and the spring 605 can work together to cause the pen tip of the pen refill 601 to extend or retract from the main body structure 100 when the cap 604 is pressed.

[0081] Understandably, once the ink in the pen refill inside the main body is used up, a new refill can be replaced to allow the writing instrument to be used for a long time.

[0082] refer to Figure 1 , Figure 2 and Figure 3At least a portion of the gripping structure 200 is integrally formed with the main structure 100. For example, the gripping structure may have one part integrally formed with the main structure, while another part is a separate structure from the main structure. For example, the gripping structure may be integrally formed with the main structure.

[0083] refer to Figure 1 For example, in conjunction with the foregoing examples, when the grip structure 200 includes a raised structure 210 and a heat-conducting element 220, the raised structure 210 and the main body structure 100 can be integrally formed. For example, after the raised structure and the main body structure are integrally formed, the heat-conducting element can be wrapped around the raised structure.

[0084] However, this disclosure is not limited to a structure in which the protruding structure and the main structure are integrally formed; the protruding structure and the main structure can also be separate structures. For example, when the protruding structure and the main structure are independent parts, the protruding structure and the main structure can be assembled together.

[0085] For example, the raised structure and the main structure can each be made of non-metallic materials to reduce the cost of the writing instrument and to reduce its weight.

[0086] For example, the grip structure and the main body structure can be separate components. Alternatively, they can be assembled together. In some examples, the grip structure can be fitted over the main body structure. This increases the flexibility and versatility of the grip structure and the main body structure, facilitating parts replacement.

[0087] refer to Figure 2 and Figure 3 In some examples, the main structure 100 has a receiving cavity 101, and a partition wall W is provided between the gripping structure 200 and the main structure 100 to separate the receiving cavity 101 from the internal space 201. This reduces the impact of the high temperature of the heating assembly 300 disposed in the internal space 201 on other structures within the receiving cavity 101.

[0088] For example, refer to Figure 2 and Figure 3 The cavity 101 can be used to house a pen refill 601. By providing a partition wall W, the impact of the heating element 300 on the ink in the pen refill 601 when it heats up can be reduced.

[0089] In some examples, the main structure has a receiving cavity that communicates with the internal space. This increases the space available for accommodating the heating element, allowing for the placement of a larger capacity battery. Furthermore, in conjunction with the aforementioned examples, when the heating element includes a temperature sensing element and a power-off protection element, it can achieve good temperature control, thus minimizing any impact on structures within the receiving cavity, such as pen refills.

[0090] For example, when the cavity is connected to the internal space, the cavity and the internal space may be without a partition wall, or they may have a partition wall with a through hole. This disclosure does not impose any restrictions on either.

[0091] refer to Figure 1 and Figure 3 In some examples, the main structure 100 includes a first end 110 and a second end 120 disposed opposite each other. In a direction perpendicular to the virtual line M connecting the first end 110 and the second end 120, the maximum dimension LM2 of the grip structure 200 is greater than the maximum dimension LM1 of the main structure 100. As a result, the grip structure 200 can better conform to the human hand in the gripping state and can provide more space for the arrangement of the heating component 300.

[0092] For example, if the main structure is roughly cylindrical, the direction perpendicular to the virtual connection line can be the radial direction of the main structure.

[0093] Figure 6 and Figure 7 This is a schematic diagram of a writing tool provided as an example in at least one embodiment of the present disclosure from different perspectives. Figure 8 and Figure 9 This is a schematic diagram of a writing instrument provided in at least one embodiment of the present disclosure under different usage states.

[0094] For example, Figure 6 This is a bottom view of the writing instrument. Figure 7 This is a front view of the writing instrument. For example, Figure 8 This diagram illustrates the usage status of writing instruments in anti-fatigue scenarios. Figure 9 The diagram illustrates the usage of writing instruments in a proper posture setting.

[0095] It should be noted that, in order to better illustrate the recessed structure on the grip structure (such as the recessed portion in the example described later), Figure 6 and Figure 7 The varying density of the dashed lines and the changes in the radius of curvature schematically illustrate the surface irregularities of the grip structure.

[0096] It should be noted that, Figure 6 and Figure 7 Only a partial structure of the writing instrument is shown schematically to illustrate its recessed design. For example, Figure 6 Other structures within the main structure 100 are not shown. However, this disclosure is not limited thereto; for example, a pen refill (such as...) may be provided within the writing instrument. Figure 2 In the case of the pen refill 601 shown, the pen refill can be seen in the bottom view of the writing instrument.

[0097] refer to Figure 1 , Figure 6 and Figure 8 In some examples, the main structure 100 has an axis AX, and the grip structure 200 is located on one side of the axis AX. The grip structure 200 includes a convex surface 202, which is configured to support the web of the hand 10 in the gripping state. Thus, the grip structure 200 can support the web of the hand 10, effectively reducing fatigue during prolonged use and facilitating continuous writing.

[0098] For example, the shape of the convex surface can basically match the shape of the web of a person's hand when gripping, so as to better fit the hand and provide better support. It is understandable that... Figure 8 In the fatigue-prevention scenario shown, the convex surface of the grip structure can conform to the web of the hand. Furthermore, the surface of the grip structure near the first end of the main body can also conform to the middle finger. This allows the hand in a comfortable gripping position to rest easily on the grip structure, enhancing the writing experience.

[0099] refer to Figure 1 , Figure 6 , Figure 7 and Figure 9 In some examples, the grip structure 200 includes a recess 230 recessed toward the main structure 100, located on the side of the grip structure 200 near the writing end of the main structure 100. The recess 230 is configured to position at least one finger of a human hand in a gripping state. Thus, in a gripping state, the finger can be located within the recess 230, thereby enabling the human hand to maintain a correct gripping posture.

[0100] For example, the first end of the main structure can be the writing end. For example, the writing end refers to the end used for writing, such as the tip of a pen refill extending from the main structure for writing.

[0101] refer to Figures 6 to 9 In some examples, the recess 230 includes at least one of the following concave surfaces: a first concave surface 231, a second concave surface, and a third concave surface. The first concave surface 231 is configured to position the thumb 12 of the hand 10. The second concave surface is configured to position the index finger 13 of the hand 10. The third concave surface is configured to position the middle finger 14 of the hand 10. For example, in Figure 9 In the illustrated posture correction scenario, the thumb, index finger, and middle finger can each be positioned within a corresponding concave surface. Therefore, the concave surfaces can be used to position the fingers of the hand, guiding the user to write with the correct posture and effectively correcting the user's grip.

[0102] It should be noted that, Figure 8 and Figure 9In the grip structure 200, the positions where the thumb 12, index finger 13 and middle finger 14 of the human hand contact the grip structure 200 may be provided with at least one of the first concave surface, the second concave surface and the third concave surface, and this disclosure does not limit this.

[0103] For example, the recess may include only a first concave surface. For example, the recess may include only a second concave surface. For example, the recess may include only a third concave surface. For example, the recess may include two of the first, second, and third concave surfaces. For example, the recess may include a first, second, and third concave surface.

[0104] At least one embodiment of this disclosure provides a heated grip structure configured to be fitted over a writing instrument. The heated grip structure includes a grip structure and a heating component. The grip structure surrounds an internal space and includes a convex surface configured to support the web of a hand in a gripping state. The heating component is disposed within the internal space. The heating component is configured to heat the grip structure.

[0105] The heated grip structure provided in this embodiment allows the user to attach it to a writing instrument. The grip structure supports the hand's forefinger during use, while the heating component warms the hand. Furthermore, the heated grip structure is compatible with multiple writing instruments, improving its portability and versatility.

[0106] For example, the writing tool can be a pen.

[0107] For example, in a posture-correcting scenario, the convex surface of the heated grip structure can support the part of the web between the thumb and forefinger near the tip of the thumb, such as the inner side of the thumb. Similarly, in a fatigue-prevention scenario, the convex surface can support the part of the web between the thumb and forefinger near the palm, such as the junction of the thumb and index finger. It is understood that, depending on the different writing habits of different users, the convex surface can support different parts of the web between the thumb and forefinger, and this disclosure does not impose any limitations on this as long as it improves the user's writing experience.

[0108] For example, the grip structure and heating component in the heated grip structure can be referred to the foregoing. Figures 1 to 7 The descriptions of the grip structure 200 and the heating component 300 in the present disclosure provide that the heated grip structure of the present disclosure also has corresponding beneficial technical effects, which will not be repeated here.

[0109] The following points need to be explained:

[0110] (1) The accompanying drawings of the embodiments of this disclosure only involve the structures involved in the embodiments of this disclosure, and other structures can be referred to the general design.

[0111] (2) Where there is no conflict, features of the same embodiment and different embodiments of this disclosure may be combined with each other.
