[0074] This embodiment provides a writing pen, such as Figures 1 - 2As shown in the figure, the writing pen includes a pen shaft 1, a center-of-gravity adjustment component 2, and a driving component 3. The center-of-gravity adjustment component 2 is disposed within the pen shaft 1, and the driving component 3 is disposed within the pen shaft 1 and connected to the center-of-gravity adjustment component 2. Among them, the driving component 3 is configured to rotate relative to the pen shaft 1 and drive the center-of-gravity adjustment component 2 to rotate, so that the center-of-gravity adjustment component 2 can move relative to the pen shaft 1 along the axial direction of the pen shaft 1 for adjusting the center of gravity of the writing pen.
[0075] For the writing pen provided in this embodiment, the driving component 3 can drive the center-of-gravity adjustment component 2 to move along the axial direction of the pen shaft 1. Since the relative position between the center-of-gravity adjustment component 2 and the pen shaft 1 is not fixed but relatively movable, during the use by the user, the center-of-gravity position of the writing pen can be freely adjusted within a certain range. When the center-of-gravity adjustment component 2 is at different positions within the pen shaft 1, the writing pen is a writing pen with adjustable center of gravity, which can not only freely adjust the center of gravity of the writing pen but also give a sense of feedback during the adjustment process.
[0076] Specifically, as Figures 3 - 5 shown, the outer shape of the pen shaft 1 is a cylindrical structure, both ends of the pen shaft 1 are open structures, and a receiving groove is provided on the outer peripheral wall of the pen shaft 1 for installing a sheath 7. The sheath 7 is sleeved outside the pen shaft 1 and received within the receiving groove. Through the interaction between the sheath 7 and the pen shaft 1, the sheath 7 can provide a suitable soft and hard feel for the user when holding the pen.
[0077] In one embodiment, as Figure 6 shown, the writing pen further includes a pen core 4, and the pen core 4 is disposed within the pen shaft 1, that is, the pen core 4 penetrates through the pen shaft 1 to facilitate writing by the user.
[0078] In one embodiment, as Figures 7 - 10 shown, the driving component 3 includes a tip sleeve 32, and the tip sleeve 32 is disposed at one end of the pen shaft 1 along the axial direction of the pen shaft 1. Among them, the outer shape of the tip sleeve 32 is similar to a conical structure, and the pen core 4 passes through the tip sleeve 32. The tip sleeve 32 plays a role in protecting the tip of the pen core 4 and is also conducive to the user's holding and writing.
[0079] Exemplarily, at least one of the ends of the pen shaft 1 and the tip sleeve 32 that are close to each other along the axial direction of the pen shaft 1 is provided with a positioning ring groove. Exemplarily, the positioning ring groove on the inner wall of the tip sleeve 32 contacts the positioning ring groove of the pen shaft 1, that is, an inverted buckle fit is adopted between the tip sleeve 32 and the pen shaft 1. The positioning ring groove can be used to position the relative position between the tip sleeve 32 and the pen shaft 1. After the tip sleeve 32 is fitted with the pen shaft 1, when the user twists the tip sleeve 32, the tip sleeve 32 can rotate relative to the pen shaft 1 to drive the center-of-gravity adjustment component 2 to move, and the tip sleeve 32 plays a role in driving the center-of-gravity adjustment component 2 to move.
[0080] It should be noted specifically that the positioning ring groove only serves to position the tip sleeve 32, but cannot fix the tip sleeve 32. The tip sleeve 32 can rotate relative to the pen barrel 1. When the tip sleeve 32 and the pen barrel 1 rotate relative to each other, the displacement of the two components of the tip sleeve 32 and the pen barrel 1 in the axial direction of the pen barrel 1 will not change.
[0081] In one embodiment, as Figures 11 - 12 shown, the driving assembly 3 further includes a transmission member 31. The transmission member 31 is disposed inside the pen barrel 1, and the center-of-gravity adjustment assembly 2 is disposed inside the transmission member 31. The tip sleeve 32 is connected to the transmission member 31. The tip sleeve 32 is configured to rotate relative to the pen barrel 1 and drive the center-of-gravity adjustment assembly 2 to rotate through the transmission member 31.
[0082] Since the tip sleeve 32 is located at the end of the pen barrel 1 and is exposed relative to the pen barrel 1, it is convenient for the user to perform a screwing operation. The tip sleeve 32 is connected to the transmission member 31, and the center-of-gravity adjustment assembly 2 is disposed inside the transmission member 31. The transmission member 31 serves as a power transmission between the tip sleeve 32 and the center-of-gravity adjustment assembly 2. As the tip sleeve 32 rotates, the center-of-gravity adjustment assembly 2 is driven to rotate through the transmission member 31.
[0083] Among them, the outer shape of the transmission member 31 is similar to a cylindrical structure. The outer diameter of the transmission member 31 is slightly smaller than the inner diameter of the pen barrel 1, and the dimensions of the transmission member 31 and the pen barrel 1 match each other. One end of the transmission member 31 facing the tip sleeve 32 is provided with a step 314, and the step 314 matches the groove on the inner wall of the pen barrel 1, serving as a positioning function between the transmission member 31 and the pen barrel 1.
[0084] Specifically, as Figures 10 - 12 shown, along the axial direction of the pen barrel 1, one of the end of the transmission member 31 facing the tip sleeve 32 and the tip sleeve 32 is provided with a clamping block 321, and the other is provided with a clamping groove 311, and the clamping block 321 is clamped in the clamping groove 311.
[0085] Exemplarily, a clamping block 321 is provided on the inner wall of the tip sleeve 32, and a clamping groove 311 is provided on the step 314 of the transmission member 31. The clamping block 321 is clamped in the clamping groove 311, so that the tip sleeve 32 and the transmission member 31 form an integral structure. As the tip sleeve 32 rotates, the transmission member 31 can rotate together with the tip sleeve 32.
[0086] It can be understood that the number of the clamping blocks 321 and the clamping grooves 311 is multiple, and the multiple clamping blocks 321 are correspondingly clamped in the multiple clamping grooves 311, further improving the connection stability between the tip sleeve 32 and the transmission member 31.
[0087] In one embodiment, along the axial direction of the pen barrel 1, a limiting member 312 is provided at one end of the transmission member 31 away from the tip sleeve 32 and inside the pen barrel 1, and a limiting mating portion 11 arranged along the circumferential direction of the pen barrel 1 is provided at the other end. The limiting member 312 abuts against the limiting mating portion 11 for limiting between the transmission member 31 and the pen barrel 1. Through the mutual cooperation of the limiting member 312 and the limiting mating portion 11, the axial displacement of the transmission member 31 relative to the pen barrel 1 is avoided.
[0088] Exemplarily, a limiting member 312 is provided at one end of the transmission member 31 away from the tip sleeve 32. The limiting member 312 can be specifically an elastic cantilever. The limiting mating portion 11 is arranged inside the pen barrel 1 at about the middle position. The limiting mating portion 11 is specifically a limiting convex block or a limiting annular groove, and the limiting convex block is of an annular structure. During initial installation, when the elastic cantilever passes through the limiting convex block, the limiting convex block abuts against and squeezes the elastic cantilever. Since the elastic cantilever has a certain elasticity, the elastic cantilever can contract and pass through the limiting convex block, facilitating the assembly of the transmission member 31. After the assembly is completed, the elastic cantilever abuts against the inner wall of the pen barrel 1, and the elastic cantilever abuts against the step surface between the limiting convex block and the pen barrel 1, playing a role of clamping and limiting to ensure that the transmission member 31 only makes rotational movements and does not displace along the axial direction of the pen barrel 1.
[0089] In one embodiment, as Figure 1 and Figures 13 - 16 shown, the center of gravity adjustment assembly 2 includes a weight member 21. The weight member 21 is arranged inside the transmission member 31 and is slidably matched with the transmission member 31. The weight member 21 can move along the axial direction of the pen barrel 1 and rotate in the circumferential direction of the pen barrel 1.
[0090] In this way, the transmission member 31 can drive the weight member 21 to rotate along the circumferential direction of the pen barrel 1. As the weight member 21 moves along the axial direction of the pen barrel 1, the transmission member 31 can also be in guiding cooperation with the weight member 21 to provide a guiding effect for the weight member 21 during the center of gravity adjustment process to ensure the smooth movement of the weight member 21.
[0091] In one embodiment, as Figures 13 - 14 shown, the weight member 21 includes a slider 211. The slider 211 is arranged inside the transmission member 31. The slider 211 is slidably matched with the transmission member 31 along the axial direction of the pen barrel 1. A threaded boss 2111 is provided on one of the outer wall of the slider 211 and the inner wall of the pen barrel 1, and a threaded groove 12 is provided on the other. The threaded boss 2111 and the threaded groove 12 are in threaded cooperation.
[0092] When the slider 211 rotates as the transmission member 31 rotates, due to the meshing of the thread bosses 2111 on the outer wall of the slider 211 and the thread grooves 12 on the inner wall of the pen shaft 1, a structure similar to a lead screw and nut is formed between the pen shaft 1 and the slider 211 at this time. Under the action of this thread fit, the slider 211 slides axially along the pen shaft 1 relative to the transmission member 31. Since the slider 211 has a certain weight, when the slider 211 moves, the overall center of gravity of the writing pen will also move, so as to achieve the purpose of adjusting the center of gravity of the writing pen.
[0093] Specifically, as Figures 13 - 14 shown, the slider 211 includes a main body portion 2112. The main body portion 2112 is arranged inside the transmission member 31 and is in sliding fit with the transmission member 31. The outer shape of the main body portion 2112 is an arc structure, or it can also be a part of a cylindrical structure. The outer diameter of the main body portion 2112 is slightly smaller than the inner diameter of the transmission member 31, which is conducive to installing the main body portion 2112 into the transmission member 31. And during the movement of the slider 211, the transmission member 31 will not move with the movement of the slider 211. The transmission member 31 can play a role of guiding fit for the main body portion 2112, improving the smoothness of the movement of the slider 211.
[0094] Specifically, the slider 211 further includes a limit boss 2113. The limit boss 2113 is connected to the main body portion 2112 and is located on one side of the main body portion 2112 along the radial direction of the pen shaft 1 and facing the transmission member 31. The transmission member 31 is provided with a limit through hole 313 along the axial direction of the pen shaft 1. The limit boss 2113 is arranged in the limit through hole 313 and is in sliding fit with the limit through hole 313.
[0095] Among them, the limit through hole 313 is specifically a rectangular through hole structure, and the limit through hole 313 can also be called a rectangular window. The limit boss 2113 is specifically a rectangular boss structure. Since the main body portion 2112 is located on the inner wall of the transmission member 31, the limit boss 2113 protrudes from the main body portion 2112 in the direction facing the transmission member 31. The limit boss 2113 is arranged in the limit through hole 313, so that the limit boss 2113 can pass through the limit through hole 313. When the transmission member 31 rotates with the tip sleeve 32, the side wall of the limit through hole 313 contacts the limit boss 2113, and the transmission member 31 can drive the slider 211 to rotate through the limit boss 2113 to realize the follow-up process. In addition, the limit through hole 313 can also guide the limit boss 2113, which is used to plan and limit the movement path of the limit boss 2113, further improving the guiding fit effect.
[0096] Among them, the thread boss 2111 or the thread groove 12 is arranged on the limit boss 2113. The limit boss 2113 passes through the limit through hole 313, so that a thread fit is realized between the limit boss 2113 and the pen shaft 1. The limit through hole 313 also plays a role of avoiding the limit boss 2113, so that the limit boss 2113 is exposed relative to the transmission member 31.
[0097] In this way, when the user rotates the tip sleeve 32 to drive the transmission member 31 to rotate, under the limiting action of the limiting boss 2113 of the slider 211 and the limiting through hole 313 of the transmission member 31, the transmission member 31 drives the slider 211 to rotate, and the threaded boss 2111 of the slider 211 and the threaded groove 12 of the pen barrel 1 are engaged with each other. Under the action of the helix in the pen barrel 1, the slider 211 has a tendency to move towards the tip sleeve 32, thereby realizing the process of adjusting the center of gravity of the writing pen.
[0098] Exemplarily, as Figures 13 - 14 shown, the slider 211 further includes an extension portion 2114, and the extension portion 2114 is disposed at at least one end of the limiting boss 2113 along the axial direction of the pen barrel 1; wherein, the threaded boss 2111 or the threaded groove 12 is disposed on the extension portion 2114.
[0099] By adding the extension portion 2114 on the limiting boss 2113, an additional setting position is added for the threaded boss 2111 or the threaded groove 12, that is, several more turns of the threaded boss 2111 or the threaded groove 12 can be provided on the outer peripheral wall of the entire slider 211, thereby improving the transmission effect between the slider 211 and the pen barrel 1, and improving the rapidity and accuracy of the movement of the slider 211.
[0100] It can be understood that the number of the main body portions 2112, the limiting bosses 2113, and the extension portions 2114 is two. The two main body portions 2112 and the two limiting bosses 2113 form a similar annular structure, and the central hole of the annular structure is used to penetrate the pen core 4. The limiting boss 2113 is disposed between the two main body portions 2112, that is, the two main body portions 2112 are disposed oppositely, the two limiting bosses 2113 are disposed oppositely, and the two extension portions 2114 are correspondingly disposed on the two limiting bosses 2113.
[0101] In one embodiment, as Figures 13 - 14 shown, the main body portion 2112 is provided with a deformation portion 2115 for elastic deformation of the main body portion 2112.
[0102] When the slider 211 moves to both ends of the limiting through hole 313 along the axial direction of the pen barrel 1, if the tip sleeve 32 is continuously screwed forcefully, it will force the transmission member 31 to continue rotating. Since the main body portion 2112 is provided with the deformation portion 2115, the strong rotational torque will force the slider 211 to generate slight elastic deformation, causing a tooth skipping situation between the threaded boss 2111 on the slider 211 and the threaded groove 12 of the pen barrel 1, thereby protecting the threaded boss 2111 of the slider 211 from being damaged and extending the service life of the writing pen.
[0103] Exemplarily, a notch is formed in the main body portion 2112 of the slider 211 to form a deformation portion 2115. The notch can be used to reduce the structural strength of the slider 211, thereby facilitating the deformation of the slider 211.
[0104] In one embodiment, as Figures 15 - 16 shown, the weight member 21 further includes a weight 212. The weight 212 can be specifically a weight ring or a weight block. The weight 212 is disposed at one end of the slider 211 along the axial direction of the pen barrel 1 and facing the tip sleeve 32.
[0105] When the slider 211 moves axially, it drives the weight 212 to move along the axial direction of the pen barrel 1. The weight 212 is used to increase the weight of the weight member 21, making the change in the center of gravity adjustment of the writing pen more obvious.
[0106] Among them, a clamping boss 2116 is provided inside the extension portion 2114 of the slider 211 (as Figures 13 - 14 shown). The clamping boss 2116 is clamped to the outer wall of the weight 212, enabling the weight 212 to move synchronously with the slider 211. And it is fixed by means of clamping, which is convenient for installation and assembly.
[0107] During installation, after installing the weight 212 into the slider 211, the slider 211 is assembled inside the transmission member 31. The two limiting bosses 2113 of the slider 211 pass through the limiting through holes 313 of the transmission member 31. After the rotating member and the slider 211 are assembled, they are assembled together from the open end of the pen barrel 1 into the inner cavity of the pen barrel 1. At this time, the thread boss 2111 on the slider 211 and the thread groove 12 on the pen barrel 1 are engaged with each other. Then, the limiting member 312 of the transmission member 31 abuts against the limiting cooperation portion 11 of the pen barrel 1 to complete the assembly process of the weight 212, the slider 211, the transmission member 31 and the pen barrel 1.
[0108] In one embodiment, as Figure 1 and Figure 17 shown, the center of gravity adjustment assembly 2 further includes a first elastic member 22. The first elastic member 22 can be a cylindrical spring. The first elastic member 22 is disposed inside the transmission member 31, and both ends of the first elastic member 22 abut against the transmission member 31 and the weight member 21 respectively.
[0109] Specifically, during installation, the first elastic member 22 is installed into the rotating member from one end of the transmission member 31 facing the limiting member 312. One end of the first elastic member 22 abuts against the step 314 of the transmission member 31, and the other end abuts against the weight 212.
[0110] Since the first elastic member 22 is in a free and loose state when not compressed, the weight of the first elastic member 22 is evenly distributed at this time. When the slider 211 and the counterweight 212 move axially, the counterweight 212 will compress or release the first elastic member 22. After the first elastic member 22 is compressed, the coiled rings of the first elastic member 22 are compressed to one end, and at this time, the entire weight of the first elastic member 22 is on the compressed length segment.
[0111] For example, when the slider 211 and the counterweight 212 move towards the tip sleeve 32, the first elastic member 22 is compressed at this time. If the first elastic member 22 is compressed to the maximum extent, the center of gravity of the entire writing pen is close to the tip sleeve 32 at this time. When the slider 211 and the counterweight 212 move in the opposite direction away from the tip sleeve 32, the first elastic member 22 is released at this time. If the first elastic member 22 is released to the maximum extent, the center of gravity of the entire writing pen is far from the tip sleeve 32.
[0112] Therefore, when the slider 211 and the counterweight 212 are displaced towards the tip sleeve 32, the center of gravity of the writing pen continuously changes with the compressed length of the first elastic member 22, thereby realizing the process of adjusting the center of gravity of the writing pen.
[0113] In addition, when the center of gravity of the writing pen is close to the tip sleeve 32, since the first elastic member 22 is compressed, rotating the tip sleeve 32 at this time will result in a heavier rotation feel. When the center of gravity of the writing pen is far from the tip sleeve 32, since the first elastic member 22 is released, rotating the tip sleeve 32 at this time will result in a lighter rotation feel. Through the compression and release of the first elastic member 22, a feedback feeling of the center of gravity moving back and forth can also be given to the user, thereby facilitating the user to select the center of gravity position of the entire writing pen suitable for themselves.
[0114] In one embodiment, as Figure 18 shown, the writing pen further includes a second elastic member 5. The second elastic member 5 is disposed outside the pen core 4. The second elastic member 5 is disposed between the tip sleeve 32 and the transmission member 31 and is used for resetting the pen core 4.
[0115] Specifically, a limiting rib 322 is provided inside the tip sleeve 32, an annular boss 41 is provided on the outer wall of the pen core 4, one end of the second elastic member 5 abuts against the limiting rib 322, and the other end abuts against the annular boss 41.
[0116] In one embodiment, as Figure 1 and Figures 19 - 23 shown, the writing pen further includes a pressing component 6. The pressing component 6 is disposed at one end of the pen barrel 1 away from the tip sleeve 32 and abuts against the pen core 4. The pressing component 6 can move relative to the pen barrel 1 along the axial direction of the pen barrel 1 to drive the pen core 4 to move, realizing the pressing process, which is beneficial for the pen core 4 to write and reset and be stored.
[0117] Specifically, the pressing component 6 includes a top cap 61, a rotating wheel 62, a pressing core 63, and a pressing head 64. The top cap 61 is disposed within the pen barrel 1 and at an end of the pen barrel 1 away from the tip sleeve 32. The rotating wheel 62 is disposed within the top cap 61 and at the tail end of the refill 4. The pressing core 63 is disposed within the top cap 61. One end of the pressing core 63 can abut against the rotating wheel 62, and the other end is connected to the pressing head 64. The pressing head 64 is disposed on the outer wall of the pen barrel 1.
[0118] When the user presses the pressing head 64, the refill 4 is pushed to move through the pressing core 63 and the rotating wheel 62, so that the refill 4 extends or retracts relative to the tip sleeve 32. If the refill 4 rotates with the slider 211, the refill 4 will drive the rotating wheel 62 to rotate relative to the top cap 61, without affecting the positions of the pressing core 63 and the pressing head 64 relative to the pen barrel 1.
