Detailed Implementation
[0040] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0041] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" may be used based on the structure of the relevant component itself, or based on the orientation of the relevant components when they are used together. For example, a cavity includes a first chamber formed by "recessing" the end face of one of the first and second joint ends, meaning that the end face of the joint end is recessed into itself to form the first chamber; the "outer" wall of the other or the "inner" wall of the first chamber forms an annular rib, where "outer wall" refers to its outer wall surface and "inner wall" refers to its inner wall surface.
[0042] In this disclosure, the terms "first," "second," etc., are used to distinguish one element from another and do not indicate any order or importance. When the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0043] Reference Figures 1-7 A writing pen is provided, comprising a first pen barrel 1 having a first writing end 101 and a first connecting end 102, and a second pen barrel 2 having a second writing end 201 and a second connecting end 202. A connecting cord 5 connects the first connecting end 102 and the second connecting end 202. The first connecting end 102 and the second connecting end 202 are configured to be detachably assembled, and after assembly, a cavity is formed between them to accommodate the connecting cord 5. Here, the writing end refers to the end of the writing pen used for writing, which includes the pen refill (described below). The writing properties of the writing end are not limited; for example, it can be electromagnetic writing, dot matrix writing, ink writing, pencil writing, etc., and can be designed adaptably according to needs. The two connecting ends are designed to be detachably assembled into one unit, and the two can be... Figures 4-7 The axially aligned assembly shown may also be axially offset or even at an angle, and this disclosure does not limit this. The detachable assembly method of the first engagement end 102 and the second engagement end 202 may be threaded, hole-shaft mating, etc., which will be described in detail below.
[0044] Reference Figures 1-3 It shows a storage state in which the first joint end 102 and the second joint end 202 are separated from each other; Figures 4-7 This shows the usage state in which the first joint end 102 and the second joint end 202 are assembled together.
[0045] This disclosure does not limit the manner in which the cavity is formed; for example, it can be formed by the first chamber and the second chamber mentioned below. See also Figure 4 It shows a schematic diagram of the assembly process of the first joint end 102 and the second joint end 202. In this state, the first joint end 102 and the second joint end 202 are axially aligned and gradually approach each other, while the connecting rope 5 is gradually compressed and stored in the cavity.
[0046] This disclosure does not limit the type of connecting rope 5 or how it is connected to the first joint end 102 and the second joint end 202. For example, in embodiments of this disclosure, the connecting rope 5 can be a nylon rope, hemp rope, cotton rope, spring rope, etc. The connecting rope 5 can be connected to the corresponding joint end by means of bonding, pre-embedded injection molding, knotting, etc.
[0047] By using the above technical solution, a writing pen with two writing ends is provided. In use, the first connecting end 102 and the second connecting end 202 are assembled into one unit, thus forming a dual-purpose pen with different writing functions at both ends. Users can choose to use one end according to their needs, satisfying the versatility of the writing pen's functions. Furthermore, the cavity housing the connecting rope 5 improves the neatness and comfort of the dual-purpose pen in use, preventing the connecting rope 5 from being exposed and affecting the user experience. After use, the first pen body 1 and the second pen body 2 can be detached from the first connecting end 102 and the second connecting end 202. This avoids the first pen body 1 and the second pen body 2 being too long in the assembled state, occupying too much space, or being inconvenient to store or carry. In the detached state, the writing pen can also be hung using a hook or similar device via the connecting rope 5. In addition, the connecting rope ensures that the first pen body 1 and the second pen body 2 always remain connected, preventing the loss of one and facilitating user organization and storage.
[0048] Reference Figures 1-3 In the embodiments of this disclosure, the connecting cord 5 can be a spring cord. This design, compared to ordinary flexible cords (hemp rope, cotton rope, etc.), makes the regular spiral structure of the spring cord easier to store, unfold, and compress, facilitating the switching between the writing pen's use and storage states without easily becoming messy. Furthermore, this spiral structure allows for an appropriate increase in the diameter of the connecting cord 5 within a given accommodating space (the cavity mentioned below), ensuring its strength.
[0049] Reference Figures 1-3 In embodiments of this disclosure, the cavity may include a first chamber 601 formed by recessing the end face of one of the first engagement end 102 and the second engagement end 202, with the other end extending into the first chamber 601. This allows for a detachable assembly of the two components. Of course, when the other end extends into the first chamber 601, it is necessary to ensure that the first chamber 601 still retains some space for accommodating the connecting rope 5.
[0050] To ensure the connection stability of the first engagement end 102 and the second engagement end 202 when the other is inserted into the first chamber 601, and to prevent easy separation of the two, refer to Figures 1-3In some embodiments of this disclosure, annular ribs 603 may be formed on the outer wall of the other component or the inner wall of the first chamber 601. When the other component is inserted into the first chamber 601, the annular ribs 603 can be pressed between the inner wall of the first chamber 601 and the outer wall of the other component. That is, the annular ribs 603 can create an interference fit when the other component is inserted into the first chamber 601, making it difficult for it to detach from the first chamber 601. It should be noted that in this case, disassembly and assembly can be achieved with only slight force, making the operation convenient. Of course, in other embodiments, annular ribs 603 may also be formed on the outer wall of the other component and the inner wall of the first chamber 601 respectively, so that during assembly, the locking relationship of the two annular ribs 603 ensures that the other component is not easily detached from the first chamber 601.
[0051] In some other embodiments, the cavity may also include a second chamber 602 formed by recesses from the end face of the other. With this design, when the first engaging end 102 and the second engaging end 202 are assembled, the connecting rope 5 can be partially accommodated in the first chamber 601 and partially in the second chamber 602. Compared to having only the first chamber 601, the design of the second chamber 602 can increase the accommodating space for the connecting rope 5.
[0052] Reference Figures 1-3 In some embodiments of this disclosure, the writing pen may further include a U-shaped cap 7, which may have a first opening 701 for inserting the first writing end 101 and a second opening 702 for inserting the second writing end 201. By inserting the first writing end 101 and the second writing end 201 into the corresponding first opening 701 and second opening 702, respectively, the writing pen is obtained in a retracted state. The U-shaped cap can prevent the two writing ends of the writing pen from being exposed, thus providing protection. In this retracted state, its axial dimension is relatively... Figures 4-7 The usage period can be halved, saving space, and it can be hung on hooks and other structures via the connecting rope 5.
[0053] In addition to the U-shaped pen cap 7, refer to Figure 6 and Figure 7 In some embodiments of this disclosure, the writing pen may further include a vertical pen cap 13, which can be selectively attached to either the first writing end 101 or the second writing end 201 when the writing pen is in use. For example, when the first writing end 101 is used for writing, the vertical pen cap 13 is attached to the second writing end 201.
[0054] In some embodiments of this disclosure, the first pen barrel 1 may include an electromagnetic pen refill 3 mounted on the first writing end 101, and the second pen barrel 2 may include a dot matrix pen refill 4 mounted on the second writing end 201. That is, the aforementioned pen barrel includes a barrel portion and a pen refill mounted on the barrel portion, with the pen refill mounted on the writing end of the barrel portion. By mounting an electromagnetic pen refill 3 and a dot matrix pen refill 4 on the two writing ends respectively, the pen can achieve a dual-use function, meaning it can be used with two different writing media. (Refer to...) Figure 8 The electromagnetic pen refill 3 may include a copper wire coil 804, which is used to interact with the electromagnetic membrane 11 mentioned below; the dot matrix pen refill 4 may be an ink pen refill, which is used to interact with specially made dot matrix paper. Since the structure and working principle of the dot matrix pen refill 4 and the electromagnetic pen refill 3 are well known to those skilled in the art, they will not be described in detail here.
[0055] To facilitate the disassembly, repair, and replacement of the electromagnetic pen refill 3, please refer to... Figure 8 In the embodiments of this disclosure, the end of the electromagnetic pen refill 3 furthest from its tip may be provided with an external thread 801, and the end face of the first writing end 101 may be formed with a first mounting hole 802 for mounting the electromagnetic pen refill 3. The first mounting hole 802 may be provided with an internal thread 803 that mates with the external thread 801, thereby enabling the electromagnetic pen refill 3 to be detachably mounted to the first writing end 101 through thread engagement. (Refer to...) Figure 8 In this embodiment, the internal thread 803 is provided at a position near the bottom of the first mounting hole 802, and the portion of the first mounting hole 802 near the opening can also be used to accommodate the copper wire coil 804.
[0056] In some embodiments of this disclosure, the end face of the second writing end 201 may be formed with a second mounting hole 904. The inner diameter of the second mounting hole 904 gradually decreases from the opening to the bottom of the hole, so that the dot matrix pen refill 4 can be press-fitted into the second mounting hole 904. With this design, the dot matrix pen refill 4 can be disassembled and installed simply by applying an external force along the axial direction.
[0057] Reference Figure 7In some embodiments of this disclosure, the end face of the second writing end 201 may also form a third mounting hole 903 adjacent to the second mounting hole 904. The writing pen may also include an infrared fill light 901 disposed in the third mounting hole 903 for emitting infrared rays toward the tip of the dot matrix pen refill 4, and an image acquisition unit 902 disposed in the third mounting hole 903 for acquiring and recording the position information of the tip of the dot matrix pen refill 4. With this design, when the second writing end 201 writes on the dot matrix paper, the infrared fill light 901 can emit infrared rays toward the position of the dot matrix paper corresponding to the pen tip, thereby displaying the dot matrix information of the dot matrix paper. The image acquisition unit 902 records the displayed dot matrix information and analyzes and obtains the writing trajectory of the dot matrix pen refill 4 through a built-in chip or the like. The writing trajectory can be transmitted to a display module (e.g., display screen 10) for display. In embodiments of this disclosure, the image acquisition unit 902 may be a camera or the like.
[0058] Reference Figures 9-11 According to a second aspect of this disclosure, an electronic device is provided, comprising the aforementioned writing pen and a display screen 10, wherein the display screen 10 is adapted to receive writing signals from the writing pen. Since this electronic device possesses all the beneficial effects of the aforementioned writing pen, further details are omitted here. Here, the electronic device can be a liquid crystal display blackboard, a tablet, a mobile phone, a learning machine, etc.
[0059] Reference Figure 10 In some embodiments of this disclosure, an electromagnetic film 11 may be arranged at the bottom of the display screen 10 to locate the coordinates of the electromagnetic pen refill 3 through the principle of electromagnetic induction, thereby determining the handwriting of the electromagnetic pen refill 3. The electromagnetic pen refill 3 can realize electronic handwriting and data storage on the display screen 10 with the built-in electromagnetic film 11. The handwriting can be intuitively aligned and page turning can be controlled by software. Since the working principles of the electromagnetic pen refill 3 and the electromagnetic film 11 are well known to those skilled in the art, they will not be described in detail here.
[0060] Reference Figure 11 In some embodiments of this disclosure, the first pen 1 is adapted to write on the display screen 10, specifically referring to the pen tip of the first pen 1 writing on the display screen 10. The electronic device may also include a writing medium 12 adapted to cooperate with the second pen 2, and the writing signal of the second pen 2 on the writing medium 12 can be displayed on the display screen 10, specifically referring to the pen tip of the second pen 2 writing on the writing medium 12. With this design, a single writing pen can simultaneously write on the display screen 10 and the writing medium 12, while also enabling all handwriting to be digitally saved, providing possibilities for subsequent content analysis and recommendation, and improving user choice and experience.
[0061] In the embodiments of this disclosure, the writing medium 12 can be writing paper to simulate the real writing feel, such as dot matrix paper. The dot matrix recognition principle can be used to realize the electronic writing of the dot matrix pen refill 4 on the dot matrix paper, while solving the problems of alignment and page turning. Since the working principles of the dot matrix pen refill 4 and the dot matrix paper are well known to those skilled in the art, they will not be described in detail here.
[0062] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.
[0063] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.
[0064] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
