It should be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application can be practiced in sequences other than those illustrated or described herein and that references to "first," "second," etc. distinguish It is usually one category, and the number of objects is not limited. For example, there may be one or more first objects. In addition, "and/or" in the specification and claims means at least one of the connected objects, and the character "/" generally means that the related objects are an "or" relationship.

The pen provided by the embodiment of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

The pen disclosed in this application can be an electronic pen used in electronic equipment such as a tablet computer and a mobile phone, or can be a mechanical pencil or a gel pen used for writing on paper. Please refer to FIGS. 1-14 , the pen may include a pen holder 100 and a pen cap. Wherein, the pen holder 100 is usually held by the user's hand, and a first accommodation hole 101 may be provided in the pen holder 100, and the first accommodation hole 101 may be arranged along the axial direction of the pen holder 100, and the first accommodation hole 101 may be used for accommodating The relevant parts of the pen, taking the electronic pen as an example, you can set the refill, Components such as power supply and sensor are placed in the first accommodation hole 101 to realize related functions such as writing.

As shown in FIGS. 1 to 3 , the pen cap may include a cap shell 300 and an inner core 200 . Wherein, the cap shell 300 may be provided with a second receiving hole 301 , and the first end 210 of the inner core 200 is movably arranged in the second receiving hole 301 . The second end 220 of the inner core 200 extends out of the cap 300 and can extend into the first receiving hole 101 to connect with the pen holder 100 .

Generally speaking, components such as pen core and power supply are arranged at the head of the pen holder 100, while the pen cap is arranged at the tail of the pen holder 100. Device maintenance and replacement, etc.

After the pen cap is connected to the pen container 100, the cap shell 300 is the exposed part of the pen cap, while the inner core 200 is completely covered and wrapped by the cap shell 300 and the pen container 100, as mentioned above: the first part of the inner core 200 The end portion 210 is located in the second receiving hole 301 , and the second end portion 220 of the inner core 200 is located in the first receiving hole 101 , and the inner core 200 is used for realizing connection. The shape of the cap shell 300 can be set to be consistent with the shape of the pen container 100, for example, the cap shell 300 and the pen container 100 are both hexagonal prisms.

In this way, when the second end portion 220 is connected to the pen holder 100 , the cap shell 300 can rotate to the first angle relative to the inner core 200 . In this way, the cap shell 300 can realize the shape matching with the pen holder 100 at the first angle. The shape matching is specifically: the cap shell 300 realizes the change of the angular position through rotation, so that its own contour can be rotated to align with the contour of the pen holder 100 , so that the contours of the two are consistent and there will be no misalignment. Taking the shape of a hexagonal prism as an example, when the cap shell 300 is at the first angle, the six sides of the cap shell 300 are flush with the six sides of the pen container 100, and the edges of the cap shell 300 are also aligned with the edges of the pen container 100. Of course, other shapes can also be used. For example, the cross sections of the cap shell 300 and the pen container 100 are oval or other special-shaped surfaces.

At the same time, when the second end 220 is connected to the pen holder 100, the pen holder 100 and the cap shell 300 form a coating on the inner core 200. The opening of the receiving hole 101 , the pen holder 100 and the cap shell 300 enclose a first receiving chamber, and the inner core 200 is accommodated in the first receiving chamber.

Under this setting, the pen cap can not only be effectively connected to the pen holder 100 through the inner core 200, but also can be consistent with the shape of the pen holder 100 through the cap shell 300, so as to effectively prevent dislocation after connection and ensure the appearance consistency of the pen. And for the electronic pen, the maintenance of this appearance consistency can effectively avoid the interference caused by the misalignment of the pen holder and the pen cap when the electronic pen is not in use, so that the magnetic surface arranged around the pen can be effectively adsorbed and fixed on the pen on electronic equipment.

Further, as shown in FIG. 2 , FIG. 7 and FIG. 10 , the first end portion 210 may be provided with a first limiting portion 211 , and the cap shell 300 may be provided with a second limiting portion 311 . The second end 220 is provided with an external thread, and the pen container 100 is provided with an internal thread matching the external thread. The cap 300 can move relative to the inner core 200 to a first position. Generally speaking, the cap shell 300 can move to the first position along the axis direction of the pen cap, and rotate to the first angle around the axis direction of the pen cap, so that the cap shell 300 can choose to move or move relative to the inner core 200 according to the needs of the movement. turn.

The first position can be understood as a position for limiting the cap 300 . Specifically, as shown in FIG. 2 , FIG. 11 and FIG. 12 , when the cap shell 300 is located at the first position, the first limiting portion 211 and the second limiting portion 311 are limitedly fitted. In this way, under the constraints of the position-limiting fit, the inner core 200 can rotate with the cap shell 300, and under the rotation of the inner core 200, the second end 220 can be screwed to the pen holder 100 with the rotation of the inner core 200, Thereby, the threaded connection between the pen cap and the pen container 100 is realized.

As shown in Figure 2, Figure 13 and Figure 14, when the second end 220 is connected to the pen holder 100 and the cap shell 300 leaves the first position, the first limiting part 211 and the second limiting part 311 are released. With limited fit, the cap shell 300 and the inner core 200 are released from mutual restraint, so that the cap shell 300 can rotate to a first angle relative to the inner core 200 , and then the shape of the cap shell 300 and the pen holder 100 can be matched.

In this setting, the disassembly and assembly of the pen container 100 and the pen cap is realized by threaded connection, and the connection is firm It is effective, and it is also convenient to realize disassembly, thereby improving the connection firmness and disassembly portability of the device of the present application.

Further, as shown in FIG. 2 , the pen may further include an elastic member 400 . The elastic member 400 may be configured as a spring, an elastic pad, or other structures. The elastic member 400 is disposed in the second receiving hole 301 , and the elastic member 400 is disposed between the inner core 200 and the bottom of the second receiving hole 301 . When the cap 300 leaves the first position, the elastic member 400 is elastically deformed, and the cap 300 can be driven by the elastic member 400 at a second angle to return to the first position.

Taking the structure shown in FIG. 2 , FIG. 11 and FIG. 12 as an example, the elastic member 400 and the inner core 200 are sequentially arranged along the axial direction of the pen cap, and are arranged sequentially along the direction in which the inner core 200 protrudes outside the cap shell 300 . Under such setting, when the pen cap is not installed in the pen holder 100 , the elastic member 400 will elastically deform to keep the cap shell 300 away from the inner core 200 , and then keep the cap shell 300 at the first position.

Specifically, the cap shell 300 can be rotated to a second angle while away from the first position, so that the first limiting portion 211 is aligned with the second limiting portion 311 , and then the elastic member 400 drives the cap shell 300 to move to the second angle. The first position is to realize the limited cooperation between the first limiting part 211 and the second limiting part 311, and through the elastic force generated by the elastic member 400, the first limiting part 211 and the second limiting part 311 are fixed in the limiting position. The matching position. Therefore, it is convenient to install the pen cap on the pen holder 100 .

As shown in Figures 11 to 14, when the pen cap is connected to the pen holder 100, the operator can press the pen cap to move the cap shell 300 along the axial direction of the pen cap to approach the inner core 200, so that the first limit The position portion 211 and the second limiting portion 311 will be separated from each other and the limiting fit will be released, so that the cap shell 300 leaves the first position, and the elastic member 400 continues to elastically deform, for example, the elastic member 400 is in a compressed state. At this time, the cap shell 300 can be turned to a first angle, so that the cap shell 300 matches the pen holder 100 .

When it is necessary to disassemble the pen cap from the pen holder 100, the pen cap is separated from the pen holder 100, and the cap shell 300 is rotated to a second angle so that the first stopper 211 is aligned with the second stopper 311 again, and then the cap shell 300 is released. , and under the action of the driving force generated by the elastic member 400, the cap shell 300 moves away from the inner core 200 Direction movement to the first position, so that the first limiting part 211 and the second limiting part 311 re-establish limited cooperation, so as to realize the state initialization of the pen cap, so as to prepare for the next assembly in the pen holder 100. It can be seen that the arrangement of the elastic member 400 can facilitate the assembly and disassembly between the pen cap and the pen container 100 .

Further, for the specific structure of the first limiting part 211 and the second limiting part 311, one of the first limiting part 211 and the second limiting part 311 can be a limiting groove, and the other can be In order to match the limit block of the limit groove, the limit cooperation between the first limit part 211 and the second limit part 311 is specifically: the limit block is engaged with the limit groove.

In this application, the first limiting part 211 is used as a limiting block, and the second limiting part 311 is designed as a limiting groove. Specifically, as shown in Fig. 2, Fig. 9 and Fig. 10, the second accommodating hole 301 has a first hole portion and a second hole portion communicating with each other, and the first hole portion is arranged in the second accommodating hole 301 away from the second end. On one side of the portion 220, the cross-sectional area of the first hole perpendicular to the axial direction of the cap is larger than the cross-sectional area of the second hole perpendicular to the axial direction of the cap, that is, the second receiving hole 301 has a stepped hole structure. The end surface of the first hole close to the second hole is the first stop surface 312, the first stop surface 312 can be understood as the stepped surface of the second receiving hole 301, wherein the limiting groove is provided on the first stop surface 312, The limiting block is disposed on a peripheral portion of the first end portion 210 .

When the cap shell 300 is at the first position, the cap shell 300 will rotate to the second angle, and at this time, the limit block and the limit groove are limitedly matched, as shown in FIG. 11 and FIG. 12 .

When the cap 300 is away from the first position, at least part of the first end 210 is located in the first hole, the limiting block is located in the first hole, and the limiting block and the limiting groove are released from the limiting cooperation. In this way, the cap shell 300 can be rotated to the first angle to match the shape of the pen holder, and at the same time, the limit block can be matched with the first stop surface 312 in this state. It can be seen that the stop fit can prevent the cap shell 300 from appearing in the axial direction of the pen cap. Excessive movement, thereby preventing abnormalities such as separation of the cap shell 300 and the inner core 200, as shown in Fig. 13 and Fig. 14 .

Further, both the first limiter 211 and the second limiter 311 can be provided in multiples, so that the limiter The effect is stronger.

Further, as shown in FIG. 4 , FIG. 9 , FIG. 13 and FIG. 14 , the end surface of the pen container 100 facing the cap shell 300 is provided with a third limiting portion 102 , and the end surface of the cap shell 300 facing the pen container 100 is provided with a fourth limiting portion 313. When the cap shell 300 is rotated to the first angle, the cap shell 300 can move to a second position relative to the inner core 200 , so that the third limiting portion 102 and the fourth limiting portion 313 are limitedly fitted.

The first position and the second position can be understood as two different positions of the cap shell 300 in the axial direction of the pen, and the first position is a position where the cap shell 300 is far away from the pen container 100 , and the second position is that the cap shell 300 is close to the pen container 100 s position. The limit cooperation between the third limiting part 102 and the fourth limiting part 313 can ensure that when the cap shell 300 is in the second position, the rotation of the cap shell 300 is constrained, thereby ensuring that the cap shell 300 can be effectively positioned at the first angle. Fixed to prevent abnormal rotation of the cap shell 300, thereby ensuring effective matching between the cap and the pen container 100, so as to better ensure the appearance and performance of the pen.

For the specific structure of the third limiting part 102 and the fourth limiting part 313, one of the third limiting part 102 and the fourth limiting part 313 is a limiting hole, and the other can be a limiting pin , when the cap shell 300 rotates to the first angle and the cap shell 300 moves to the second position, the limit pin can be inserted into the limit hole, so as to realize the limit fit.

Further, as shown in FIG. 2 and FIG. 4 , the cap shell 300 may be provided with a first stop portion 500 , and the pen holder 100 may be provided with a second stop portion 103 . When the cap shell 300 is moved to the second position, the first stop portion 500 stops and fits with the second stop portion 103 .

The stopper cooperation between the first stopper part 500 and the second stopper part 103 can prevent the capshell 300 from constraining the axial movement of the capshell 300 along the pen cap when the capshell 300 is in the second position, thereby keeping the capshell 300 in the second position. The second position prevents abnormal separation of the cap shell 300 and the pen holder 100, further ensuring the appearance and performance of the pen.

Further, the cap shell 300 can also move to a third position relative to the inner core 200, specifically, Figure 12 is understood as the first position of the cap shell 300, Figure 13 is understood as the third position of the cap shell 300, and Figure 14 is understood as the second position of the cap shell 300, that is, the third position is between the first position and the second position . When the cap shell 300 is in the third position, the first limiting portion 211 and the second limiting portion 311 release the limiting fit, so that the cap shell 300 can be rotated to the first angle. At the same time, when the cap shell 300 is in the third position, the first stopper 500 is separated from the second stopper 103 , and the third limiter 102 is separated from the fourth limiter 313 .

However, when the cap shell 300 is in the second position and at the first angle, the first stopper part 500 and the second stopper part 103 perform a stop fit to prevent the cap shell 300 from moving along the pen cap axial direction. ; The third limit portion 102 and the fourth limit portion 313 carry out a limit fit to prevent the cap shell 300 from rotating around the pen cap axis. This further ensures the fixing of the cap shell 300 at the second position, and better realizes the effective matching between the cap shell 300 and the pen container 100 .

In actual operation, as shown in Figure 12 and Figure 13, the user can first hold the pen holder 100 and press the cap 300, so that the cap 300 moves from the first position to the third position along the axis of the pen, and in this state The cap 300 is rotated down to a first angle. Then, as shown in FIG. 14 , continue to press the cap shell 300, so that the cap shell 300 moves to the second position along the axial direction of the pen cap, so that the first stopper 500 moves to the second stopper along with the cap shell 300 103 for stop fit, and make the third limit portion 102 and the fourth limit portion 313 limit fit, so as to complete the installation of the pen cap relative to the pen container 100 .

It can be seen that, compared to the operation method of directly pressing the cap shell 300 into the second position and then turning it to the first angle, since the first stopper 500 and the second stopper 103 have not yet been established at the third position connection relationship, and the cap shell 300 and the pen holder 100 are still in a separated state, so when in the third position, the cap shell 300 rotates more smoothly, and it will be easier to rotate to the first angle, which increases the operability of the device of the present application.

For the specific structure of the first stopper 500 and the second stopper 103, the first stopper 500 One and the second stopper 103 can be an annular groove, and the other is an annular clamping bar, and the annular clamping bar is clamped in the annular groove, so as to realize the fixing of the cap 300 at the second position. For example, the first stopper 500 is an annular ridge provided on the cap 300, and the second stopper 103 is an annular groove, and the first stopper 500 can be integrally formed on the cap 300, This ensures overall strength.

In this application, the first stop portion 500 is set as a sealing ring. The outer periphery of the cap shell 300 may be provided with a first sealing groove, the sealing ring is sleeved in the first sealing groove, and the sealing ring has a first portion protruding from the first sealing groove. And the second stop portion 103 can be a second sealing groove disposed around the first receiving hole 101 .

In this way, when the cap shell 300 moves to the second position, one end of the cap shell 300 provided with the sealing ring can extend into the first receiving hole 101, so that the first part of the sealing ring is accommodated in the second sealing groove, so that the sealing The ring stop fits in the second sealing groove.

This setting can not only prevent the cap shell 300 from moving along the pen axis when it is in the second position, but also realize the sealing of the cap shell 300 in the second position, thereby eliminating the gap between the cap shell 300 and the pen holder 100 , to prevent dust, stains, etc. from entering the inside of the pen holder 100 to cause pollution.

Further, the cap shell 300 may include a first housing part 310 and a second housing part 320 , and the second receiving hole 301 is provided in the first housing part 310 . The second housing part 320 is disposed in the second receiving hole 301 and is located on a side of the second receiving hole 301 away from the inner core 200 .

The second receiving hole 301 can be set as a through hole, and the second housing part 320 is usually provided with a structure such as a blocking cover and blocked at the opening position of the second receiving hole 301. The setting of the through hole facilitates the manufacture of related molds. Thus, manufacturing difficulty and manufacturing cost are reduced.

Further, a detachable connection is made between the first end portion 210 and the second end portion 220 , so that the inner core 200 can be easily loaded into the cap shell 300 . Specifically, since the first limiting portion 211 is usually arranged around the first end portion 210 , assembly interference may occur during normal assembly, resulting in failure to assemble, so the application adopts the above configuration. When assembling, the first end portion 210 can be firstly separated from the first housing part 310 The rear end is loaded into the second accommodating hole 301, and then the second end portion 220 is loaded into the second accommodating hole 301 from the front end of the first shell member 310, and then the first end portion 210 and the second end portion 220 are assembled. Connect, and finally install the second housing part 320, and then complete the installation of the entire pen cap.

As for the specific connection method between the first end 210 and the second end 220, the two can be assembled in the form of threaded connection, welding, bonding, etc., and the inner core 200 in this application also includes a connecting piece 230, the connecting piece The first hole portion of the connector 230 is connected to the first end portion 210 , and the second hole portion of the connecting member 230 is connected to the second end portion 220 . The connecting piece 230 can be a stud, and the first end 210 and the second end 220 are respectively provided with threaded holes matching the connecting piece 230, thereby realizing the interconnection of the first end 210 and the second end 220, and the connecting piece 230 is also It may be an expansion nail, so as to realize the interconnection of the first end portion 210 and the second end portion 220 through a tension connection, which will not be described in detail here.

Further, the first end portion 210 is provided with a fifth limiting portion 212 , the second end portion 220 is provided with a sixth limiting portion 221 , and the fifth limiting portion 212 and the sixth limiting portion 221 are limitedly matched. For the detachably connected first end portion 210 and second end portion 220, this arrangement can prevent relative rotation between the first end portion 210 and the second end portion 220, so that the cap can hold the inner core 200 in The screw is effectively screwed into the first receiving hole 101 , and then the pen cap is connected to the pen holder 100 .

Further, the outer peripheral portion of the pen holder 100 is provided with a first flat surface 104 , and the outer peripheral portion of the cap shell 300 is provided with a second flat surface 314 . When the second end 220 is connected to the pen container 100 and the cap shell 300 is rotated to the first angle, the first plane 104 coincides with the second plane 314, so that the cap shell 300 and the pen container 100 realize the above-mentioned shape matching, and then The appearance performance of the pen is guaranteed, and the first plane 104 and the second plane 314 together constitute the placement surface of the pen, so that when the pen is not in use, the pen can be placed on the desktop or the like through the placement surface to prevent rolling displacement.
