The embodiment of the application provides a pen. Referring to fig. 1 to 3, the pen 100 includes a pen body 10 and a light source assembly 20.

The pen body 10 is provided therein with a hollow portion penetrating in a longitudinal direction of the pen body 10. The pen body 10 includes a transparent body 11 and a coating 12 disposed on one side of the body, and the coating 12 has a hollow portion 121.

The light source assembly 20 is disposed in the hollow portion of the pen body 10, the light source assembly 20 includes a light source 21, and light emitted from the light source 21 exits through the hollow portion 121.

In the pen provided by the embodiment of the application, the body part 11 is transparent, the coating 12 is arranged on one side of the body part 11, the hollowed-out part 121 is arranged on the coating 12, light emitted by the light source 21 of the light source assembly 20 can be emitted out through the hollowed-out part 121 of the coating 12, the interestingness of use of a user can be improved, and the hollowed-out part can play a role in propaganda when the light emitted by the light source 21 is emitted out through the hollowed-out part 121 by arranging the hollowed-out part of the coating 12 into patterns or characters; for the scheme that sets up the fretwork on this somatic part 11, this application embodiment can not make the intensity of body of a pen 10 reduce, can avoid a body intensity lower and easily appear damaging.

In one embodiment, the coating 12 is disposed on the outside of the body portion 11. So set up, can facilitate the preparation of pen body 10. The coating 12 may be formed by spraying paint, and the coating 12 may be a single color or may be multiple colors, for example, the coating 12 may include multiple portions, one color for each portion. The coating 12 is an opaque film layer, so that the user cannot see the internal structure of the pen body 10 through the coating 12, which can improve the aesthetic property of the pen 100.

In one embodiment, the pen 100 further includes a pen core 40, and the pen body 10 is movably disposed in a hollow portion of the pen body 10. The pen core 40 comprises a pen point 41 and a pen core rod 42 connected with the pen point, wherein the pen point 41 is positioned on one side of the pen core rod 42, which is far away from the light source component 20. The pen 100 includes a writing state and a non-writing state. In the writing state, the pen point 41 of the pen core 40 is at least partially exposed out of the pen body 10; in the non-writing state, the nib 41 of the pen core 40 is housed in the pen body 10.

In one embodiment, the pen 100 further includes a knock mechanism 30 and a knock head 33, and the light source assembly 20, the cartridge 40, the knock mechanism 30, and the knock head 33 are movably disposed in the hollow portion. Two ends of the pressing mechanism 30 respectively abut against the pressing head 33 and the light source assembly 20, and the other end of the light source assembly 20 abuts against the pen core 40. The pressing head 33 moves along the length direction of the pen body 10 to drive the pressing mechanism 30 to move along the length direction of the pen body 10, and further the pressing mechanism 30 drives the light source assembly 20 and the pen core 40 to move along the length direction of the pen body 10. In this way, the user pushes the light source assembly 20 to move by pressing the thumb 33, so that the light source assembly 20 pushes the pen core 40 to move, and the arrangement of the light source assembly 20 does not affect the action of the thumb mechanism 30 on the pen core 40; the switching between the writing state and the non-writing state of the pen 100 can be realized by pressing the thumb 33, which is convenient for the user to operate.

In one embodiment, the end of the thumb press 33 facing away from the light source assembly 20 is at least partially exposed from the pen body 10. This facilitates the user to press the thumb press 33.

In one embodiment, the pressing mechanism 30 includes a first pressing member 31 and a second pressing member 32, a first end of the first pressing member 31 is abutted against the pressing head 33, a second end of the first pressing member 31 is abutted against a first end of the second pressing member 32, and a second end of the second pressing member 32 is abutted against the light source assembly 20. The pressing head 33 moves along the length direction of the pen body 10, drives the first pressing member 31, the second pressing member 32, the light source assembly 20 and the pen core 40 to move along the length direction of the pen body 10, and simultaneously drives the second pressing member 32 to rotate, and the rotation of the second pressing member 32 triggers the light source 21 to emit light or extinguish. The user can trigger the light source 21 to emit light or extinguish by pressing the press button 33, so that the control of the light source 21 is simpler and the operation of the user is convenient.

In one embodiment, when the pen 100 is in a writing state, the light source 21 is opposite to the hollow-out portion 121 in a radial direction of the pen body 10; when the second pressing member 32 triggers the light source 21 to emit light or turn off, the pen 100 is in a writing state. When the pen 100 is in the non-writing state, the hollow portion 121 and the light source 21 may be offset in a radial direction of the pen body 10. When the light source 21 emits light, the pen 100 is in a writing state, the light source 21 is opposite to the hollow portion 121 in a radial direction of the pen body 10, and light emitted by the light source 21 is emitted through the hollow portion 121. Thus, when the user uses the pen 100 to write, the light emitted from the light source 21 is emitted, which is more beneficial to improving the interest of the user.

In one embodiment, the pen 100 further includes a conductive portion 321, the conductive portion 321 is disposed at the second end of the second pressing member 32, and the light source 21 includes a first conductive end and a second conductive end. The light source assembly 20 further comprises a battery 22 and a conductive structure 26, wherein a first power end of the battery 22 is electrically connected to a first conductive end of the light source 21, and a second power end of the battery 22 is electrically connected to the conductive portion 321. One end of the conductive structure 26 is electrically connected to the second conductive end of the light source 21, and the free end of the conductive structure 26 faces the second snap member 32. The pressing head 33 drives the second pressing member 32 to rotate, and the rotation of the second pressing member 32 drives the conductive part 321 to rotate, so that the conductive part 321 is contacted with or separated from the free end of the conductive structure 26, thereby triggering the light source 21 to emit light or extinguish. One of the first and second power terminals of the battery 22 is a positive electrode, and the other is a negative electrode. The light source assembly 20 may include only one cell 22, or may include a plurality of cells 22, with the plurality of cells 22 forming a battery pack.

When the user presses the pressing member 33, the first pressing member 31, the second pressing member 32 and the light source assembly 20 are pushed to move along the length direction of the pen body, and simultaneously the second pressing member 32 is driven to rotate, and the second pressing member 32 drives the conductive portion 321 to rotate. When the second pressing member 32 rotates to the free end of the conductive structure 26 to contact with the conductive portion 321, the light source 21 and the battery 22 form a closed loop, and the light source 21 emits light; when the second snap member 32 rotates to separate the free end of the conductive structure 26 from the conductive portion 321, the light source 21 stops emitting light.

In one embodiment, the second power end of the battery 22 is disposed at an end of the battery 22 facing the second snap member 32, the light source 21 is disposed at a side of the battery 22 facing away from the second snap member 32, and the conductive structure 26 is disposed at a side of the battery 22.

The conductive portion 321 includes a conductive sheet 322 and a conductive connector 323. Referring to fig. 4, the conductive sheet 322 includes a main body 3221 and a strip 3222 formed by extending one side of the main body 3221, the main body 3221 is located in a central area of the second end of the second pressing member 32, one end of the conductive connecting member 323 is connected to the main body 3221, and the other end of the conductive connecting member 323 is connected to the second power end of the battery 22. The pressing head 33 drives the second pressing member 32 to rotate, so that the end of the strip portion 3222 is in contact with or separated from the free end of the conductive structure 26, thereby triggering the light source 21 to emit light or extinguish.

The main body 3221 of the conductive sheet 322 is disposed in the central area of the second end of the second pressing member 32, so as to ensure the reliability of the connection between the conductive connecting member 323 and the second power end of the battery during the rotation of the second pressing member 32, and avoid the problem of poor electrical connection between the conductive connecting member 323 and the second power end of the battery 22. The position of the free end of the conductive structure 26 in the radial direction of the pen body 10 is not changed, when the second pushing member 32 rotates, the end of the strip portion 3222 rotates, the distance between the strip portion 3222 and the free end of the conductive structure 26 changes, and only when the strip portion 3222 contacts the free end of the conductive structure 26, the light source 21 and the battery 22 form a loop.

In one embodiment, the conductive connector 323 is a first elastic member. When the user presses the knock bar 33 to change the writing state and the non-writing state of the pen 100, the first elastic member rotates with the second knock member 32. By arranging the conductive connecting member 323 as the first elastic member, the conductive connecting member 323 can be ensured to be always in contact with the second power end of the battery 22, and the situation that the conductive connecting member 323 is in poor contact with the second power end of the battery 22 in the rotating process of the second pressing member 32 is avoided.

In one embodiment, the light source assembly 20 further includes a receiving portion 27, the light source 21 and the battery 22 are received in the receiving portion 27, and the light source 21 is at least partially exposed from the receiving portion 27. Thus, the light source assembly 20 is a whole and can move along the length direction of the pen body 10 in the pen body 10; the light source 21 is at least partially exposed from the receiving portion 27, and the receiving portion 27 does not affect the emission of the light from the light source 21.

In one embodiment, the light source 21 is located on a side of the battery 22 facing away from the second snap member 32, the receiving portion 27 includes a conductive sleeve 23 and an insulating sleeve 24 located on a side of the conductive sleeve 23 facing away from the pen core 40, and a side portion of the insulating sleeve 24 is provided with a conductive post 25 electrically connected to the conductive sleeve 23. The conductive structure 26 includes the conductive sleeve 23 and the conductive post 25.

By arranging the insulating sleeve 24, the situation that the light source 21 always emits light because the conductive structure 26 is always in contact with the strip portion 3222 of the conductive sheet 322 can be avoided; by arranging the conductive structure 26 to include the conductive sleeve 23, the conductive sleeve 23 plays a role in accommodating the battery and also plays a role in electrical connection, and two roles are realized at the same time, which is helpful for simplifying the structural complexity of the light source assembly 20; any position of the conductive sleeve 23 contacting the second conductive end of the light source 21 can make the two electrically connected, and the reliability of the electrical connection can be ensured.

The free end of the conductive structure 26 refers to the end of the conductive post 25 facing away from the conductive sleeve 23. The position of the conductive post 25 in the circumferential direction is always kept unchanged, and when the strip portion 3222 of the conductive sheet 322 rotates to contact with the end of the conductive post 25 away from the conductive sleeve 23 in the process of rotating the second knock member 32, the light source 21 emits light.

In one embodiment, the inner wall of the pen body 10 is provided with a limiting member in limiting fit with the second pressing member 32. When the pen is in a writing state, the pressing mechanism 30 is in a first state, the second pressing member 32 is limited at a first position by the limiting member, and the pen point 41 of the pen core 40 partially extends out of the hollow part; when the pen is in a non-writing state, the pressing mechanism 30 is in a second state, the stopper is disengaged from the second pressing member 32, the second pressing member 32 is in a second position, and the tip 41 of the cartridge 40 is accommodated in the hollow portion. The distance from the second position to the end of the pen body 10 close to the snap 33 is smaller than the distance from the first position to the end of the pen body 10 close to the snap 33.

In one embodiment, the limiting member comprises a plurality of guide rails, and one end of each guide rail, which is close to the pen core, is provided with a first helical tooth; the plurality of guide rails are provided at intervals on the inner wall of the hollow portion in the circumferential direction of the pen body 10.

The outer side wall of the second snap member 32 is provided with a plurality of first guide grooves 325 adapted to the guide rails, and one end of the second snap member 32 away from the pen core 40 is provided with a plurality of second helical teeth 324 adapted to the first helical teeth. Two second helical teeth 324 are arranged between every two adjacent first guide grooves 325.

A plurality of second guide grooves 312 adapted to the guide rails are formed on the outer side wall of the first snap member 31, and the guide rails are located in the corresponding second guide grooves 312; the end of the first knock member 31 close to the pen core 40 is provided with a third helical tooth 311 matched with the second helical tooth 324. The first pressing member 31 moves along the length direction of the pen body 10, and the third helical teeth 311 abut against the second helical teeth 324 to drive the second pressing member 32 to move.

When the pen 100 is in the writing state, the first helical teeth 311 contact with the second helical teeth 324, and the second snap member 32 is limited at the first position by the guide rail. When the pen 100 is in the non-writing state, the first helical teeth are disengaged from the second helical teeth 324, the guide rail is located in the corresponding first guide groove 325, and the second snap member 32 is located at the second position.

In one embodiment, the pen 100 further comprises a second resilient member 60; one end of the second elastic member 60 abuts against the plunger rod 42, and the other end abuts against the inner wall of the pen body 10. The second elastic member 60 cooperates with the knock mechanism 30 to switch between the writing state and the non-writing state of the pen.

In one embodiment, a third helical tooth 311 is disposed between every two adjacent second guide grooves 312 of the first snap member 31. The inner wall of the pen body 10 is provided with guide rails having the same number as the first guide grooves 325 and the second guide grooves 312. The chamfer angle of the first helical teeth 311 is substantially the same as the chamfer angle of the second helical teeth 324.

When the pen is not in use, the pen is in a non-writing state, the knock head 33 and the pen core 40 are both located at the initial position, the pen tip 41 of the pen core 40 is accommodated in the hollow portion, the knock mechanism 30 is in the second state, the stopper is disengaged from the second knock member 32, the second knock member 32 is located at the second position, and the guide rail is integrally fitted into the second guide groove 312 of the first knock member 31 and the first guide groove 325 of the second knock member 32. The user presses the pressing head 33 to move along the length direction of the pen body 10, and drives the first pressing member 31 to move until the third inclined tooth 311 of the first pressing member 31 contacts with the inclined surface of the second inclined tooth 324 of the second pressing member 32, and since the guide rail is in the first guide groove of the second pressing member 32, the rotation of the second pressing member 32 is limited, so that the first pressing member 31 drives the second pressing member 32 to move along the guide rail, and the second pressing member 32 drives the pen core 40 to move until the pen point 41 partially extends out of the hollow portion, and the second elastic member 60 is compressed. The guide rail will gradually disengage from the first guiding groove of the second snap member 32 during the downward movement of the second snap member 32, and after the second snap member 32 loses the steering limitation of the guide rail, the second helical tooth 324 of the second snap member 32 starts to perform a rotation movement, and the guide rail moves along the slope of the second helical tooth 324 until the edge of the guide rail is locked, and at this time, the third helical tooth 311 is just in a position contacting with the second helical tooth 324. The guide rail limits the second snap-action member 32 to the first position, and prevents the pen core 40 from rebounding under the action of the second elastic member 60, so that the pen point 41 is kept extending, and the pen is in a writing state.

After the pen is used, the user presses the pressing head 33 again to move along the length direction of the pen body 10, and drives the first pressing member 31 to move until the third inclined tooth 311 of the first pressing member 31 contacts with the inclined surface of the second inclined tooth 324 of the second pressing member 32, the first pressing member 31 presses the second pressing member 32, the second pressing member 32 is not limited in the rotating direction due to the separation of the guide rail from the second pressing member 32, the second pressing member 32 rotates simultaneously with the pressing of the first pressing member 31, and the guide rail gradually slides down along the second inclined tooth 324 into the first guide groove 325 of the second pressing member 32. The second knock member 32 has no radial restriction of the guide rail, the second elastic member 60 is not pressed to generate rebound, the pen core 40 rebounds to the initial position under the action of the second elastic member 60, the pen point 41 is accommodated in the hollow portion, and the pen 100 is in a non-writing state.

In one embodiment, the second knock member 32 is provided with two or more first guide grooves 325. Thus, when the second pressing member 32 rotates for one turn, the pen 100 is switched between the writing state and the non-writing state twice or more, but only when the pen 100 is in the writing state for one time, the light source 21 emits light, so that the user can select the light source 21 to emit light or not to emit light when using the pen 100 to write, which is equivalent to the scheme that the light source 21 emits light when the pen 100 is in the writing state for each time, thereby being helpful to improve the user experience and saving the electric energy of the battery 22. In one embodiment, the second knock member 32 is provided with two first guide grooves 325, so that the light source 21 emits light when the pen 100 is in a double writing state. In other embodiments, the second snap member 32 is provided with three or more first guide grooves 325.
