[0074] The present embodiment provides a writing pen, such as Figures 1-2As shown, the writing pen comprises a pen barrel 1, a gravity center adjusting assembly 2 and a driving assembly 3, the gravity center adjusting assembly 2 is arranged in the pen barrel 1, and the driving assembly 3 is arranged in the pen barrel 1 and connected to the gravity center adjusting assembly 2. Among them, the driving assembly 3 is configured to rotate relative to the pen barrel 1, and drive the gravity center adjusting assembly 2 to rotate, so that the gravity center adjusting assembly 2 can move along the axial direction of the pen barrel 1 relative to the pen barrel 1, for adjusting the gravity center of the writing pen.
[0075] The writing pen provided by the embodiment can drive the gravity center adjusting assembly 2 to move along the axial direction of the pen barrel 1 by the driving assembly 3. Since the relative position between the gravity center adjusting assembly 2 and the pen barrel 1 is not fixed but moves relatively, the user can freely adjust the gravity center position of the writing pen within a certain range during use. When the gravity center adjusting assembly 2 is located at different positions of the pen barrel 1, the writing pen is a gravity center adjustable writing pen, which can freely adjust the gravity center of the writing pen and also give feedback during the adjustment process.
[0076] Specifically, as shown in the drawings, Figures 3-5 The pen barrel 1 has a cylindrical structure, both ends of the pen barrel 1 are open structures, and the outer peripheral wall of the pen barrel 1 is provided with a containing groove for installing a sheath 7. The sheath 7 is sleeved on the outside of the pen barrel 1 and contained in the containing groove. Through the mutual action between the sheath 7 and the pen barrel 1, the sheath 7 can provide a soft and hard suitable hand feeling for the user when holding the pen.
[0077] In one embodiment, as shown in the drawings, Figure 6 The writing pen further comprises a pen core 4, which is arranged in the pen barrel 1, i.e. the pen core 4 penetrates the pen barrel 1, which is convenient for the user to write.
[0078] In one embodiment, as shown in the drawings, Figures 7-10 The driving assembly 3 comprises a sharp sleeve 32 arranged at one end of the pen barrel 1 along the axial direction of the pen barrel 1. Among them, the sharp sleeve 32 has a shape similar to a conical structure, and the pen core 4 penetrates the sharp sleeve 32, which plays a role in protecting the pen point of the pen core 4 and is convenient for the user to hold and write.
[0079] Exemplarily, at least one of the pen barrel 1 and the sharp sleeve 32 close to each other along the axial direction of the pen barrel 1 is provided with a positioning ring groove. Exemplarily, the positioning ring groove on the inner wall of the sharp sleeve 32 and the positioning ring groove of the pen barrel 1 are in contact with each other, i.e. the sharp sleeve 32 and the pen barrel 1 adopt reverse fitting. The relative position between the sharp sleeve 32 and the pen barrel 1 can be positioned by the positioning ring groove. After the sharp sleeve 32 cooperates with the pen barrel 1, when the user twists the sharp sleeve 32, the sharp sleeve 32 can rotate relative to the pen barrel 1 to drive the gravity center adjusting assembly 2 to move, and the sharp sleeve 32 plays a role in driving the gravity center adjusting assembly 2 to move.
[0080] It should be noted that the positioning ring groove only serves to position the tip sleeve 32, but cannot fix the tip sleeve 32, and 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 tip sleeve 32 and the pen barrel 1 along the axial direction of the pen barrel 1 does not change.
[0081] In one embodiment, as shown in Figures 11-12 The driving assembly 3 further includes a transmission member 31 arranged in the pen barrel 1, and the gravity center adjusting assembly 2 is arranged in the transmission member 31. The tip sleeve 32 is connected to the transmission member 31, and the tip sleeve 32 is configured to rotate relative to the pen barrel 1 and drive the rotation of the gravity center adjusting assembly 2 through the transmission member 31.
[0082] Since the tip sleeve 32 is located at the end of the pen barrel 1 and exposed relative to the pen barrel 1, it is convenient for the user to rotate and operate. The tip sleeve 32 is connected to the transmission member 31, and the gravity center adjusting assembly 2 is arranged in the transmission member 31. The transmission member 31 serves as a power transmission between the tip sleeve 32 and the gravity center adjusting assembly 2. With the rotation of the tip sleeve 32, the transmission member 31 drives the rotation of the gravity center adjusting assembly 2.
[0083] The transmission member 31 has a cylindrical structure, and the outer diameter of the transmission member 31 is slightly smaller than the inner diameter of the pen barrel 1. The sizes of the transmission member 31 and the pen barrel 1 are matched with each other. The end of the transmission member 31 towards the tip sleeve 32 is provided with a step 314, and the step 314 is matched with the groove in the inner wall of the pen barrel 1 to serve as a positioning between the transmission member 31 and the pen barrel 1.
[0084] Specifically, as shown in Figures 10-12 The end of the transmission member 31 towards the tip sleeve 32 and one of the tip sleeve 32 are provided with a clamping block 321, and the other is provided with a clamping groove 311. The clamping block 321 is clamped in the clamping groove 311.
[0085] For example, the clamping block 321 is arranged on the inner wall of the tip sleeve 32, and the clamping groove 311 is arranged 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. With the rotation of the tip sleeve 32, the transmission member 31 can rotate together with the tip sleeve 32.
[0086] It can be understood that the number of clamping blocks 321 and clamping grooves 311 is multiple, and multiple clamping blocks 321 are clamped in multiple clamping grooves 311, which further improves 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, the transmission member 31 is provided with a limiting member 312 at one end away from the tip sleeve 32 and the interior of the pen barrel 1, and the other end is provided with a limiting matching part 11 arranged along the circumferential direction of the pen barrel 1, the limiting member 312 abuts against the limiting matching part 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 matching part 11, the axial displacement of the transmission member 31 relative to the pen barrel 1 is avoided.
[0088] Exemplarily, the limiting member 312 is arranged at one end of the transmission member 31 away from the tip sleeve 32, and the limiting member 312 can be a flexible cantilever in particular, and the limiting matching part 11 is arranged at the interior of the pen barrel 1 at about the middle position, and the limiting matching part 11 is a limiting protrusion or a limiting ring groove in particular, and the limiting protrusion is a ring structure. When initially installed, the flexible cantilever passes through the limiting protrusion, and the limiting protrusion abuts against and extrudes the flexible cantilever, and since the flexible cantilever has a certain elasticity, the flexible cantilever can shrink to pass through the limiting protrusion, facilitating the assembly of the transmission member 31. After assembly is completed, the flexible cantilever abuts against the inner wall of the pen barrel 1, and the flexible cantilever abuts against the step surface between the limiting protrusion and the pen barrel 1, playing a role of clamping and limiting, so as to ensure that the transmission member 31 only rotates and does not displace along the axial direction of the pen barrel 1.
[0089] In one embodiment, as shown in Figure 1 and Figures 13-16 , the gravity center adjusting assembly 2 includes a counterweight component 21, which is arranged in the transmission member 31 and is in sliding cooperation with the transmission member 31, and the counterweight component 21 can move relative to the axial direction of the pen barrel 1 and rotate relative to the circumferential direction of the pen barrel 1.
[0090] In this way, the transmission member 31 can drive the counterweight component 21 to rotate along the circumferential direction of the pen barrel 1, and the transmission member 31 can also guide the counterweight component 21 when the counterweight component 21 moves along the axial direction of the pen barrel 1, so as to provide a guiding action for the counterweight component 21 during the gravity center adjustment, so as to ensure the smoothness of the movement of the counterweight component 21.
[0091] In one embodiment, as shown in Figures 13-14 , the counterweight component 21 includes a sliding block 211, which is arranged in the transmission member 31 and is in sliding cooperation with the transmission member 31 along the axial direction of the pen barrel 1, and one of the outer wall of the sliding block 211 and the inner wall of the pen barrel 1 is provided with a threaded boss 2111, and the other is provided with a threaded groove 12, and the threaded boss 2111 and the threaded groove 12 are in threaded cooperation.
[0092] When the slider 211 rotates with the rotation of the transmission member 31, due to the engagement of the thread convex post 2111 and the thread groove 12 between the outer wall of the slider 211 and the inner wall of the pen barrel 1, a screw nut structure is formed between the pen barrel 1 and the slider 211 at this time, and under the thread cooperation, the slider 211 slides along the axial direction of the pen barrel 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, thereby achieving the purpose of adjusting the center of gravity of the writing pen.
[0093] Specifically, as shown in Figures 13-14 The slider 211 includes a main body part 2112 which is arranged in the transmission member 31 and is in sliding cooperation with the transmission member 31. The outer shape of the main body part 2112 is a circular arc structure, which can also be part of a cylindrical structure, and the outer diameter of the main body part 2112 is slightly smaller than the inner diameter of the transmission member 31, which is beneficial to the installation of the main body part 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, and the transmission member 31 can cooperate with the main body part 2112 to guide the movement of the slider 211, thereby improving the smoothness of the movement of the slider 211.
[0094] Specifically, the slider 211 further includes a limiting convex post 2113 which is connected to the main body part 2112 and located on the side of the main body part 2112 along the radial direction of the pen barrel 1 and towards the transmission member 31. The transmission member 31 is provided with a limiting through hole 313 along the axial direction of the pen barrel 1, and the limiting convex post 2113 is arranged in the limiting through hole 313 and in sliding cooperation with the limiting through hole 313.
[0095] The limiting through hole 313 is specifically a rectangular through hole structure, which can also be referred to as a rectangular window, and the limiting convex post 2113 is specifically a rectangular convex post structure. Since the main body part 2112 is located on the inner wall of the transmission member 31, the limiting convex post 2113 is protruded on the main body part 2112 towards the transmission member 31, and the limiting convex post 2113 is arranged in the limiting through hole 313, so that the limiting convex post 2113 can pass through the limiting through hole 313. When the transmission member 31 rotates with the tip sleeve 32, the side wall of the limiting through hole 313 and the limiting convex post 2113 are in contact, and the transmission member 31 can drive the slider 211 to rotate through the limiting convex post 2113, thereby realizing the process of following movement. In addition, the limiting through hole 313 can also guide the limiting convex post 2113, which is used to plan and limit the movement path of the limiting convex post 2113, thereby further improving the guiding cooperation effect.
[0096] The thread convex post 2111 or the thread groove 12 is arranged on the limiting convex post 2113, the limiting convex post 2113 passes through the limiting through hole 313, so that the limiting convex post 2113 and the pen barrel 1 are in thread cooperation, and the limiting through hole 313 also avoids the limiting convex post 2113, so that the limiting convex post 2113 is in an exposed state relative to the transmission member 31.
[0097] In this way, the user rotates the tip sleeve 32 to drive the transmission member 31 to rotate, under the limiting effect of the limiting protrusions 2113 of the sliding block 211 and the limiting through holes 313 of the transmission member 31, the transmission member 31 drives the sliding block 211 to rotate, and the threaded protrusions 2111 of the sliding block 211 and the threaded grooves 12 of the pen barrel 1 are engaged with each other, under the effect of the screwing in the pen barrel 1, the sliding block 211 has a tendency to move to the position of the tip sleeve 32, thereby realizing the process of adjusting the center of gravity of the writing pen.
[0098] Exemplarily, as shown in Figures 13-14 , the sliding block 211 further includes an extension 2114, which is arranged at at least one end of the limiting protrusion 2113 along the axial direction of the pen barrel 1; wherein the threaded protrusion 2111 or the threaded groove 12 is arranged on the extension 2114.
[0099] By additionally arranging the extension 2114 on the limiting protrusion 2113, an additional arrangement position is provided for the threaded protrusion 2111 or the threaded groove 12, i.e. several circles of the threaded protrusion 2111 or the threaded groove 12 can be arranged on the outer peripheral wall of the entire sliding block 211, thereby improving the transmission effect between the sliding block 211 and the pen barrel 1 and improving the rapidity and accuracy of the movement of the sliding block 211.
[0100] It can be understood that the number of the main body 2112, the limiting protrusion 2113 and the extension 2114 is two, the two main bodies 2112 and the two limiting protrusions 2113 form a ring-like structure, and the central hole of the ring-like structure is used to pass the pen core 4. The limiting protrusion 2113 is arranged between the two main bodies 2112, i.e. the two main bodies 2112 are oppositely arranged, the two limiting protrusions 2113 are oppositely arranged, and the two extensions 2114 are correspondingly arranged on the two limiting protrusions 2113.
[0101] In an embodiment, as shown in Figures 13-14 , the main body 2112 is provided with a deformation portion 2115 for elastic deformation of the main body 2112.
[0102] When the sliding block 211 moves to the two ends of the limiting through hole 313 along the axial direction of the pen barrel 1, if the tip sleeve 32 is continuously twisted, the transmission member 31 will be forced to continue to rotate. Since the main body 2112 is provided with the deformation portion 2115, a strong rotating torque will force the sliding block 211 to be slightly elastically deformed, so that the threaded protrusion 2111 on the sliding block 211 and the threaded groove 12 between the pen barrel 1 will be out of gear, thereby protecting the threaded protrusion 2111 of the sliding block 211 from being damaged and prolonging the service life of the writing pen.
[0103] Exemplarily, the main body part 2112 of the sliding block 211 is provided with a notch, forming a deformation part 2115. The notch can reduce the structural strength of the sliding block 211, thereby facilitating the deformation of the sliding block 211.
[0104] In one embodiment, as shown in Figures 15-16 The weight component 21 further comprises a weight part 212, which can be a weight ring or a weight block. The weight part 212 is arranged at one end of the sliding block 211 in the axial direction of the pen barrel 1 and towards the tip sleeve 32.
[0105] When the sliding block 211 moves axially, the weight part 212 moves along the axial direction of the pen barrel 1. The weight part 212 increases the weight of the weight component 21, making the change of the center of gravity of the writing pen more obvious.
[0106] The extension part 2114 of the sliding block 211 is internally provided with a clamping boss 2116 (as shown in Figures 13-14 The clamping boss 2116 is clamped to the outer wall of the weight part 212, so that the weight part 212 can move synchronously with the sliding block 211, and is fixed by clamping, which is convenient for installation and assembly.
[0107] During installation, after the weight part 212 is installed into the sliding block 211, the sliding block 211 is assembled into the transmission member 31. The two limiting bosses 2113 of the sliding block 211 pass through the limiting through holes 313 of the transmission member 31. After the rotation member and the sliding block 211 are assembled, they are assembled into the inner cavity of the pen barrel 1 from the open end of the pen barrel 1. At this time, the threaded boss 2111 of the sliding block 211 and the threaded groove 12 are engaged with each other, and then the limiting part 312 of the transmission member 31 abuts against the limiting matching part 11 of the pen barrel 1, so as to complete the assembly process of the weight part 212, the sliding block 211, the transmission member 31 and the pen barrel 1.
[0108] In one embodiment, as shown in Figure 1 and Figure 17 The center of gravity adjusting assembly 2 further comprises a first elastic member 22, which can be a cylindrical spring. The first elastic member 22 is arranged in the transmission member 31, and the two ends of the first elastic member 22 abut against the transmission member 31 and the weight component 21, respectively.
[0109] Specifically, during installation, the first elastic member 22 is installed into the rotation member from one end of the transmission member 31 towards the limiting part 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 part 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. When the slider 211 and the counterweight 212 move axially, the counterweight 212 compresses or releases the first elastic member 22. When the first elastic member 22 is compressed, the coil of the first elastic member 22 is compressed to one end, and at this time, the weight of the first elastic member 22 is entirely on the length segment after compression.
[0111] For example, when the slider 211 and the counterweight 212 move towards the tip sleeve 32, at this time the first elastic member 22 is compressed, if the first elastic member 22 is compressed to the maximum extent, at this time the center of gravity of the entire writing pen is close to the tip sleeve 32. When the slider 211 and the counterweight 212 move reversely away from the tip sleeve 32, at this time the first elastic member 22 is released, if the first elastic member 22 is released to the maximum extent, the center of gravity of the entire writing pen is away 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 constantly changes with the length of the first elastic member 22 being compressed, 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, at this time rotating the tip sleeve 32 will cause the rotating feeling to be biased heavy. When the center of gravity of the writing pen is away from the tip sleeve 32, since the first elastic member 22 is released, at this time rotating the tip sleeve 32 will cause the rotating feeling to be biased light. Through the compression and release of the first elastic member 22, the user can also be given the feedback feeling of the front and back movement of the center of gravity, thereby facilitating the user to select the entire writing pen center of gravity position suitable for himself.
[0114] In an embodiment, as shown in Figure 18 the writing pen further comprises a second elastic member 5, the second elastic member 5 is arranged outside the refill 4, the second elastic member 5 is arranged between the tip sleeve 32 and the transmission member 31, and is used for resetting the refill 4.
[0115] Specifically, the tip sleeve 32 is provided with a limiting rib 322, the outer wall of the refill 4 is provided with an annular boss 41, 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 an embodiment, as shown in Figure 1 and Figures 19-23 the writing pen further comprises a click assembly 6, the click assembly 6 is arranged at the end of the pen barrel 1 away from the tip sleeve 32 and abuts against the refill 4, the click assembly 6 can move relative to the pen barrel 1 along the axial direction of the pen barrel 1 to drive the refill 4 to move, thereby realizing the pressing process and facilitating the writing and resetting storage of the refill 4.
[0117] Specifically, the click assembly 6 comprises a top cap 61, a rotating wheel 62, a lifting core 63 and a lifting head 64. The top cap 61 is arranged in the pen barrel 1 and located at the end of the pen barrel 1 away from the tip sleeve 32. The rotating wheel 62 is arranged in the top cap 61 and located at the tail end of the pen core 4. The lifting core 63 is arranged in the top cap 61. One end of the lifting core 63 can abut against the rotating wheel 62, and the other end is connected to the lifting head 64. The lifting head 64 is arranged on the outer wall of the pen barrel 1.
[0118] The user presses the lifting head 64 to push the pen core 4 to move through the lifting core 63 and the rotating wheel 62, so that the pen core 4 extends or retracts relative to the tip sleeve 32. If the pen core 4 rotates with the slider 211, the pen core 4 will drive the rotating wheel 62 to rotate relative to the top cap 61, which will not affect the position of the lifting core 63 and the lifting head 64 relative to the pen barrel 1.
