Description

Technical Field

[0001] This utility model relates to the field of stylus technology, and in particular to a weighted pen cap and a stylus having the pen cap. Background Technology

[0002] With the continuous advancement of technology, electronic pens have been widely used in education, office work, design, and many other fields. As a digital device that simulates traditional writing tools, the design and functions of electronic pens are constantly being optimized. However, the center of gravity distribution of electronic pens is not always reasonable, which may require users to exert extra force to maintain the stability of the pen during writing.

[0003] Chinese utility model patent (CN217543814U) discloses an electronic pen and its tip. The pen tip includes a pen head and a pen barrel, with a pen core electrically connected to the pen head inside the pen barrel. The pen head is a hollow structure surrounded by a flocked layer, which is a conductor and electrically connected to the pen core. Because the pen head surface is covered with fiber fluff, its surface smoothness is significantly reduced, breaking the conditions for adhesion and greatly reducing friction between contact surfaces. However, in actual use, the fixed center of gravity of this electronic pen cannot meet the needs of different groups. For example, some people prefer electronic pens with the center of gravity closer to the pen head, while others prefer those with the center of gravity closer to the pen tail, thus limiting the pen's functionality. Summary of the Invention

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that solves the aforementioned problems by providing a weighted pen cap and a touch pen with the pen cap.

[0005] A counterweight pen cap has a through hole, and at least two guide blocks for guiding and limiting are provided in the through hole. The two guide blocks are evenly distributed on the inner wall of the through hole and are integrally connected to the pen cap. The pen cap is provided with a first magnet, which is detachably installed on the bottom surface of the pen cap. The pen cap includes a first semicircular plate and a second semicircular plate. One side of the first semicircular plate is hinged to one side of the second semicircular plate, and the other side of the first semicircular plate can rotate around the hinge axis and is magnetically connected to the other side of the second semicircular plate.

[0006] As a further embodiment of this utility model: two guide blocks are respectively disposed on the inner surfaces of the first semicircular plate and the second semicircular plate. When the first semicircular plate and the second semicircular plate are closed, the inner surface of the second semicircular plate forms the through hole.

[0007] As a further embodiment of this utility model: a first magnetic layer is provided on the other side of the first semicircular plate, and a second magnetic layer is provided on the other side of the second semicircular plate. When the first semicircular plate rotates around the hinge axis and closes with the second semicircular plate, the first magnetic layer and the second magnetic layer attract each other.

[0008] As a further embodiment of this invention, the pen cap is also provided with a second magnet, which is detachably mounted on the top surface of the pen cap.

[0009] As a further embodiment of this utility model: the surfaces of both the first semicircular plate and the second semicircular plate are provided with a first anti-slip texture.

[0010] As a further embodiment of this invention, the pen cap is made of materials including but not limited to iron and brass.

[0011] As a further embodiment of this utility model: a stylus including the above-mentioned counterweight cap, comprising a pen tube and a pen tip, wherein the pen tip is installed at one end of the pen tube, the pen tube is provided with a first magnetic ring for magnetic connection with the bottom surface of the pen cap, the first magnetic ring is installed at one end of the pen tube near the pen tip, and the pen tube is also provided with a sliding structure for the pen cap to slide on the pen tube.

[0012] As a further embodiment of this utility model: the pen tube is also provided with a second magnetic ring, which is installed on the surface of the pen tube and forms a gripping area between the second magnetic ring and the first magnetic ring. The pen tube is also provided with an anti-slip rubber sleeve, which is fitted on the surface of the pen tube and located in the gripping area of ​​the pen tube.

[0013] As a further embodiment of this utility model: the sliding structure includes a limiting groove and a third magnet ring opened at the other end of the pen tube for inserting the guide block. One end of the limiting groove extends to the second magnet ring, and the third magnet ring is installed at the other end of the limiting groove.

[0014] As a further embodiment of this invention: the pen tube is also provided with a fourth magnet ring, which is installed on the surface of the pen tube and located in the middle section of the limiting groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model designs a pen cap with adjustable weight. The pen cap can be movably installed on the stylus. Users can change the center of gravity of the pen by adjusting the position of the pen cap according to their personal preferences, thereby meeting the usage habits of different groups of people, making the stylus more adaptable, better meeting the operating needs of different users, and significantly improving the versatility of the product and the user experience.

[0017] 2. By designing a stylus with a pen cap as a counterweight, the pen cap is slidably mounted on the pen tube. When the user slides the pen cap to magnetically connect with the second magnetic ring, the center of gravity of the pen cap shifts towards the grip area. When the pen cap slides to the tail of the stylus, the pen cap magnetically connects with the third magnetic ring, and the center of gravity of the pen cap shifts towards the tail of the stylus. This design of adjusting the center of gravity of the stylus by sliding the pen cap can better adapt to the usage needs of different users.

[0029] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Please see Figures 1-2 In this embodiment of the utility model, a counterweight pen cap 1 is provided. The pen cap 1 has a through hole 11, and at least two guide blocks 12 for guiding and limiting are provided in the through hole 11. The two guide blocks 12 are evenly distributed on the inner wall of the through hole 11. The guide blocks 12 are integrally formed with the pen cap 1. The pen cap 1 is provided with a first magnet 13, which is detachably installed on the bottom surface of the pen cap 1. The pen cap 1 includes a first semicircular plate 14 and a second semicircular plate 15. One side of the first semicircular plate 14 is hinged to one side of the second semicircular plate 15. The other side of the first semicircular plate 14 can rotate around the hinge axis and magnetically connect with the other side of the second semicircular plate 15 to form a cylindrical structure. The materials of the pen cap 1 include, but are not limited to, iron and brass.

[0031] Specifically, the first semicircular plate 14 and the second semicircular plate 15 are semicircular plate structures. When the two semicircular plates are closed together, their semicircular surfaces abut against each other to form the through hole 11 of the pen cap 1. The hinged connection between one side of the first semicircular plate 14 and one side of the second semicircular plate 15 can be achieved by using a hinge structure. The connection method of the first magnet 13 includes, but is not limited to, adhesive bonding, threaded connection, or snap-fit ​​connection. The guide block 12 can be arranged on the semicircular surface of the first semicircular plate 14 or the second semicircular plate 15, or it can be set at the semicircular surfaces of the first semicircular plate 14 and the semicircular plates respectively. The function of the guide block 12 is to be inserted into the limiting groove 27 opened in the pen tube 21 to guide and limit the position of the pen cap 1. When the user slides the pen cap 1, it can prevent it from rotating on the pen tube 21 and reduce the shaking of the pen cap 1 when sliding.

[0032] Further as Figures 6-7 As shown, in an embodiment of this utility model, two guide blocks 12 are respectively disposed on the inner surfaces of the first semicircular plate 14 and the second semicircular plate 15. When the first semicircular plate 14 and the second semicircular plate 15 are closed, the inner surface of the second semicircular plate 15 forms the through hole 11.

[0033] Further as Figure 2As shown in the embodiment of this utility model, a first magnetic layer 141 is provided on the other side of the first semicircular plate 14, and a second magnetic layer 151 is provided on the other side of the second semicircular plate 15. When the first semicircular plate 14 rotates around the hinge axis and closes with the second semicircular plate 15, the first magnetic layer 141 and the second magnetic layer 151 attract each other. The first magnetic layer 141 and the second magnetic layer 151 can be magnets, and their connection method includes, but is not limited to, bonding.

[0034] Further as Figures 1-2 As shown, in an embodiment of this utility model, the pen cap 1 is further provided with a second magnet 16, which is detachably mounted on the top surface of the pen cap 1. The connection method of the second magnet 16 includes, but is not limited to, adhesive bonding.

[0035] Further as Figures 1-8 As shown in the embodiment of this utility model, the surfaces of the first semicircular plate 14 and the second semicircular plate 15 are both provided with first anti-slip textures 17. The first anti-slip textures 17 increase the coefficient of friction for the fingers to ensure the stability of the opening and closing operation.

[0036] Please see Figures 1-7 In this embodiment of the utility model, a stylus 2 with the cap is designed. The cap 1 is slidably mounted on the pen tube 21. When the cap 1 slides and is magnetically connected to the second magnetic ring 24, the center of gravity of the cap 1 is biased towards the gripping area. When the cap 1 slides to the tail of the stylus 2, the cap 1 is magnetically connected to the third magnetic ring 26, and the center of gravity of the cap 1 is biased towards the tail of the stylus 2. This design of adjusting the center of gravity of the stylus 2 by sliding the cap 1 on the pen tube 21 can better adapt to the usage needs of different users.

[0037] Specifically, a fourth magnetic ring 28 is installed between the second magnetic ring 24 and the third magnetic ring 26, allowing the pen cap 1 to have two additional ways to adjust its center of gravity. One way is that the lower end of the pen cap 1 and the fourth magnetic ring 28 are magnetically connected, in which case the center of gravity of the stylus 2 is located in the middle of the pen tube 21, towards the gripping area. The other way is that the upper end of the pen cap 1 and the fourth magnetic ring 28 are magnetically connected, in which case the center of gravity of the stylus 2 is located in the middle of the pen tube 21, near the tail. This allows for fine adjustment of the center of gravity of the stylus 2, improving user comfort.

[0038] Further as Figures 3-8As shown in the embodiment of this utility model, a stylus 2 including the aforementioned counterweight cap 1 includes a pen tube 21 and a pen tip 22. The pen tip 22 is mounted on one end of the pen tube 21. The pen tube 21 is provided with a first magnetic ring 23 for magnetic connection with the bottom surface of the pen cap 1. The first magnetic ring 23 is mounted on the end of the pen tube 21 near the pen tip 22. The pen tube 21 is also provided with a sliding structure for the pen cap 1 to slide on the pen tube 21. Specifically, when the pen cap 1 only has the first magnet 13 at the bottom, the user can flip the pen cap 1 during use to make the first magnet 13 magnetically connected with the second magnetic ring 24 or the third magnetic ring 26. The magnetic connection between the first magnet 13 and the first magnetic ring 23 can be used to protect the pen tip 22 of the stylus 2.

[0039] Further as Figures 3-6 and Figure 8 As shown in the embodiment of this utility model, the pen tube 21 is further provided with a second magnetic ring 24, which is installed on the surface of the pen tube 21. A gripping area is formed between the second magnetic ring 24 and the first magnetic ring 23. The pen tube 21 is also provided with an anti-slip rubber sleeve 25, which is fitted onto the surface of the pen tube 21 and located in the gripping area of ​​the pen tube 21. Specifically, the anti-slip rubber sleeve 25 may have a plurality of microporous structures on its surface to increase the frictional force of gripping and achieve an anti-slip effect.

[0040] Further as Figures 3-8 As shown, in an embodiment of this utility model, the sliding structure includes a limiting groove 27 and a third magnetic ring 26 formed at the other end of the pen tube 21 for the insertion of the guide block 12. One end of the limiting groove 27 extends to the second magnetic ring 24, and the third magnetic ring 26 is installed at the other end of the limiting groove 27. Specifically, one end of the limiting groove 27 extends to the tail of the pen tube 21, and the other end extends to the area near the gripping area. The number of limiting grooves 27 corresponds to the number of guide blocks 12 provided on the pen tube 21.

[0041] The working principle of this embodiment is as follows: When the user slides the pen cap 1 and the second magnetic ring 24 to magnetically connect, the center of gravity of the pen cap 1 is biased towards the gripping area. When the pen cap 1 slides the tail of the stylus 2, the pen cap 1 is magnetically connected to the third magnetic ring 26, and the center of gravity of the pen cap 1 is biased towards the tail of the stylus 2. This design of adjusting the center of gravity of the stylus 2 by sliding the pen cap 1 can better adapt to the usage needs of different users.

[0042] Further as Figures 3-8As shown, in this embodiment of the present invention, the pen tube 21 is further provided with a fourth magnetic ring 28, which is installed on the surface of the pen tube 21 and located in the middle section of the limiting groove 27. The working principle of this embodiment is as follows: the pen cap 1 can be adjusted in two ways. One way is that the lower end of the pen cap 1 and the fourth magnetic ring 28 are magnetically connected, in which case the center of gravity of the stylus 2 is located in the middle of the pen tube 21, towards the gripping area. The other way is that the upper end of the pen cap 1 and the fourth magnetic ring 28 are magnetically connected, in which case the center of gravity of the stylus 2 is located in the middle of the pen tube 21, near the tail. This allows for fine-tuning of the center of gravity of the stylus 2, improving user comfort.

[0043] The working principle of this utility model is as follows: When the user needs to adjust the center of gravity while using the stylus 2, the pen cap 1 is opened so that the first semicircular plate 14 and the second semicircular plate 15 are in an open state. Then, the guide blocks 12 of the first semicircular plate 14 and the second semicircular plate 15 are respectively aligned with the limiting groove 27 of the pen tube 21 and closed, so that the guide blocks 12 are inserted into the limiting groove 27. At this time, the pen cap 1 is closed and installed on the pen tube 21. The pen cap 1 can slide along the direction of the limiting groove 27. When the user slides the pen cap 1 and the second magnetic ring 24 magnetically connects, the center of gravity of the pen cap 1 is biased towards the gripping area. When the pen cap 1 slides the tail of the stylus 2, the pen cap 1 is magnetically connected with the third magnetic ring 26. At this time, the center of gravity of the pen cap 1 is biased towards the tail of the stylus 2. After use, the user unfolds the pen cap 1 and takes it off the pen tube 21. When the pen cap 1 is closed, its bottom surface is magnetically connected with the third magnetic ring. At this time, the pen cap 1 covers the pen tip 22 and plays a protective role.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
