DETAILED DESCRIPTION

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be a clear and complete description of the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0046] The embodiments of the present application will be described below with reference to Figures 1 to 21 .

[0047] According to the embodiments of the present application, on the one hand, a stylus is provided, which comprises:

[0048] The stylus tip 1 comprises an insertion end 103 and an abutting section 102, and the abutting section 102 is arranged on the peripheral surface of the insertion end 103;

[0049] The pen body assembly comprises a limiting section 201 and an elastic piece 304, and the pen body assembly is formed with an accommodating hole 205. In the assembled state, the insertion end 103 is inserted into the accommodating hole 205, the abutting section 102 is located on the side of the limiting section 201 away from the stylus tip 1, and the elastic piece 304 is adapted to apply an elastic force to the insertion end 103 away from the pen body assembly, so that the abutting section 102 abuts against the limiting section 201.

[0050] When the stylus tip 1 and the pen body assembly need to be assembled, the insertion end 103 is inserted into the accommodation hole 205, the abutment section 102 is made to abut against the limiting section 201 under the elastic force of the elastic member 304, the connection of the stylus tip 1 and the pen body assembly is realized, the whole process is convenient for the user to assemble the stylus tip 1, and the experience in use is improved.

[0051] In addition, the stylus tip 1 also has a separated state, in which the abutment section 102 is located on the side of the limiting section 201 close to the stylus tip 1. When the stylus tip 1 and the pen body assembly need to be separated, for example, when the stylus tip 1 needs to be replaced, the user applies a force in the direction away from the pen body assembly to the stylus tip 1, and the stylus tip 1 can be pulled out, the whole process is convenient for the user to install and disassemble the stylus tip 1, the replacement of the stylus tip 1 is realized, and the use experience is improved.

[0052] It is worth noting that in the related art, the stylus tip 1 and the pen body assembly can be threadedly connected through threaded assembly, and the installation and disassembly of the stylus tip 1 can also be realized. However, the threaded assembly cannot realize long-term screwing in and out operation, and will be worn and jammed after long-term use, resulting in reduced user experience. In addition, this assembly design takes a long time, which is not conducive to the improvement of production line yield.

[0053] In the embodiment, the stylus tip 1 can be quickly disassembled and assembled only by plugging and unplugging the stylus tip 1, and the service life of the stylus tip 1 is prolonged while the overall structure of the stylus tip 1 and the pen body assembly is relatively simple.

[0054] The following describes various embodiments of the abutment section 102 and the limiting section 201 through multiple embodiments.

[0055] Embodiment 1

[0056] In the first embodiment, the limiting section 201 is configured to be elastically deformed under stress; and / or, the abutment section 102 is configured to be elastically deformed under stress; and / or, the insertion end 103 is configured to be elastically deformed under stress. That is, at least one of the limiting section 201, the abutment section 102, and the insertion end 103 is made of a deformable elastic material, such as rubber, elastic plastic, etc. In this way, during the disassembly and assembly of the stylus tip 1, the elastic deformation of the limiting section 201, and / or the abutment section 102, and / or the insertion end 103 is utilized to facilitate the change of the relative position of the limiting section 201 and the abutment section 102, and after assembly, the limiting section 201, and / or the abutment section 102, and / or the insertion end 103 returns to the original state, realizing abutment and limiting.

[0057] Specifically, the abutting section 102 can be made elastic only, in which case the limiting section 201 and the insertion end 103 are made rigid (i.e. not elastically deformable); or the limiting section 201 can be made elastic only, in which case the abutting section 102 and the insertion end 103 are made rigid; or the insertion end 103 can be made elastic only, in which case the abutting section 102 and the limiting section 201 are made rigid; or the abutting section 102 and the limiting section 201 can be made elastic, in which case the insertion end 103 is made rigid; or the abutting section 102 and the insertion end 103 can be made elastic, in which case the limiting section 201 is made rigid; or the limiting section 201 and the insertion end 103 can be made elastic, in which case the abutting section 102 is made rigid; or the limiting section 201, the abutting section 102 and the insertion end 103 can be made elastic.

[0058] Further, in the present embodiment, as shown in Figure 1 the barrel 2 includes a mounting end 206, and at least part of the receiving hole 205 is formed in the mounting end 206, and the limiting section 201 is arranged on the inner peripheral wall of the receiving hole 205 at the mounting end 206 of the barrel 2.

[0059] Specifically, in the present embodiment, as shown in Figure 2 the abutting section 102 and the limiting section 201 are annular, i.e. the abutting section 102 is arranged along the entire outer peripheral surface of the insertion end 103, and the limiting section 201 is arranged along the entire inner peripheral wall of the barrel 2, so that the abutting section 102 and the limiting section 201 abut each other, thereby increasing the contact area between the two, and preventing the stylus tip 1 from separating from the barrel 2.

[0060] Of course, as an alternative, the abutting section 102 can be arranged in several sections along the outer peripheral surface of the insertion end 103, and the limiting section 201 can be arranged along the entire inner peripheral wall of the barrel 2; or the limiting section 201 can be arranged in several sections along the inner peripheral wall of the barrel 2, and the abutting section 102 can be arranged along the entire outer peripheral surface of the insertion end 103; or the abutting section 102 can be arranged in several sections along the outer peripheral surface of the insertion end 103, and the limiting section 201 can be arranged in several sections along the inner peripheral wall of the barrel 2, as long as the several sections of the abutting section 102 and the several sections of the limiting section 201 can abut each other to limit the movement of the stylus tip 1.

[0061] Embodiment 2

[0062] In the second embodiment, as shown in Figure 3As shown, the insertion end 103 is provided with a hollow area 1032, and the hollow area 1032 forms a first arm 1031 with one end suspended, and the abutting segment 102 is arranged on the outer circumferential surface of the movable end of the first arm 1031. In this way, the first arm 1031 forms an elastic arm, so that in the disassembly and assembly process of the stylus tip 1, the elastic deformation of the first arm 1031 drives the abutting segment 102 to move, thereby facilitating the change of the relative position of the limiting segment 201 and the abutting segment 102, and after assembly is completed, the first arm 1031 drives the abutting segment 102 to reset and realize abutting and limiting.

[0063] It should be noted that in the embodiment, the abutting segment 102 and the limiting segment 201 can be rigid structures, for example, metal materials. That is, the abutting segment 102 or the limiting segment 201 does not need to be deformed.

[0064] Of course, as an alternative embodiment, the limiting segment 201 and / or the abutting segment 102 can also be provided as an elastic structure, that is, the limiting segment 201 and / or the abutting segment 102 is made of a deformable elastic material, for example, rubber, elastic plastic, etc. Specifically, only the abutting segment 102 can be an elastic structure, at this time, the limiting segment 201 is a rigid structure; or only the limiting segment 201 is an elastic structure, at this time, the abutting segment 102 is a rigid structure; or the abutting segment 102 and the limiting segment 201 are both elastic structures.

[0065] Further, in the embodiment, as shown in Figure 1 , Figure 3 and Figure 4 , the pen body assembly includes a pen barrel 2, the pen barrel 2 includes a mounting end 206, and at least part of a containing hole 205 is formed in the mounting end 206, and the limiting segment 201 is arranged on the inner circumferential wall of the containing hole 205 at the mounting end 206 of the pen barrel 2.

[0066] It should be noted that, as shown in Figure 3 , at least two hollow areas 1032 are arranged along the circumference of the insertion end 103, so as to correspondingly form at least two first arms 1031, and one abutting segment 102 is arranged on the outer circumference of the suspended end of each first arm 1031.

[0067] Further, in the embodiment, the limiting segment 201 is annular, and in this way, the limiting segment 201 is convenient to cooperate with the plurality of abutting segments 102.

[0068] Specifically, in the embodiment, the abutting segment 102 is provided with two. Of course, as an alternative embodiment, the number of abutting segments 102 can also be three, four, or other numbers.

[0069] Of course, as an alternative implementation, the limiting section 201 can also be arranged in several sections along the inner circumferential wall of the barrel 2, and the abutting sections 102 of the several sections abut and cooperate to limit.

[0070] Embodiment 3

[0071] In the third implementation, the limiting section 201 is configured to elastically deform under stress; and / or, the abutting section 102 is configured to elastically deform under stress; and / or, the insertion end 103 is configured to elastically deform under stress. That is, at least one of the limiting section 201, the abutting section 102, and the insertion end 103 is made of a deformable elastic material, such as rubber, elastic plastic, etc. In this way, during the disassembly and assembly of the stylus tip 1, the elastic deformation of the limiting section 201, and / or the abutting section 102, and / or the insertion end 103 facilitates the change of the relative position of the limiting section 201 and the abutting section 102, and after assembly is completed, the limiting section 201, and / or the abutting section 102, and / or the insertion end 103 returns to its original state, achieving abutting and limiting.

[0072] Specifically, only the abutting section 102 can be made of an elastic structure, in which case the limiting section 201 and the insertion end 103 are made of a rigid structure (without elastic deformation); or only the limiting section 201 is made of an elastic structure, in which case the abutting section 102 and the insertion end 103 are made of a rigid structure; or only the insertion end 103 is made of an elastic structure, in which case the abutting section 102 and the limiting section 201 are made of a rigid structure; or both the abutting section 102 and the limiting section 201 are made of an elastic structure, in which case the insertion end 103 is made of a rigid structure; or both the abutting section 102 and the insertion end 103 are made of an elastic structure, in which case the limiting section 201 is made of a rigid structure; or both the limiting section 201 and the insertion end 103 are made of an elastic structure, in which case the abutting section 102 is made of a rigid structure; or all of the limiting section 201, the abutting section 102, and the insertion end 103 are made of an elastic structure.

[0073] Further, as shown in Figure 5 , the stylus tip 1 includes the insertion end 103, and the outer circumferential surface of the insertion end 103 is provided with the abutting section 102.

[0074] Further, as shown in Figure 6 , Figure 7 , Figure 8 , the barrel assembly includes the barrel 2, the conductive lead 3, and the first locking ring 202, the first locking ring 202 is located in the barrel 2, and the limiting section 201 is arranged on the inner circumferential wall of the first locking ring 202.

[0075] In addition, the pen body assembly further comprises a second locking ring 203, which is also located in the pen barrel 2. The inner thread 2021 of the connecting end 2023 of the first locking ring 202 is connected to the outer thread 2031 of the second locking ring 203 in a threaded connection manner. The inner peripheral surface of the limiting end 2022 of the first locking ring 202 is provided with an annular limiting section 201. The limiting end 2022 contains the insertion end 103 of the stylus tip 2. The second locking ring 203 is fixedly arranged in the pen barrel 2. By arranging the limiting section 201 on the first locking ring 202, it is not necessary to arrange the limiting section 201 in the pen barrel 2, thereby effectively reducing the production difficulty of the pen barrel 2.

[0076] It should be noted that the second locking ring 203 can be fixedly connected with the pen barrel 2, or the second locking ring 203 is fixedly connected with other components in the pen barrel 2.

[0077] It should be noted that in the embodiment, the materials of the first locking ring 202 and the second locking ring 203 are metal materials (such as brass, stainless steel, etc.). In this way, the structural strength of the pen barrel 2 and the conductive pen core 3 can be enhanced.

[0078] Specifically, in the embodiment, as shown in Figure 5 , Figure 8 The abutting section 102 and the limiting section 201 are annular. In the assembled state, the abutting section 102 of the insertion end 103 abuts against the limiting section 201 of the limiting end 2022, thereby increasing the contact area of the two and avoiding separation of the stylus tip 1 from the first locking ring 202.

[0079] Of course, as an alternative embodiment, the abutting section 102 can be arranged in a plurality of sections along the outer peripheral surface of the insertion end 103. The limiting section 201 can be arranged along the inner peripheral wall of the pen barrel 2. Alternatively, the limiting section 201 can be arranged in a plurality of sections along the inner peripheral wall of the pen barrel 2. The abutting section 102 can be arranged along the outer peripheral surface of the insertion end 103. Alternatively, the abutting section 102 can be arranged in a plurality of sections along the outer peripheral surface of the insertion end 103. The limiting section 201 can be arranged in a plurality of sections along the inner peripheral wall of the pen barrel 2. Only the abutting section 102 and the limiting section 201 need to be able to abut and cooperate to limit.

[0080] Of course, as an alternative embodiment, the limiting section 201 can be arranged on the outer peripheral surface of the first locking ring 202. At this time, the inner peripheral wall of the insertion end 103 is provided with the abutting section 102. The insertion end 103 is sleeved on the outer peripheral surface of the first locking ring 202 to realize the abutting cooperation of the abutting section 102 and the limiting section 201.

[0081] Of course, as an alternative implementation, in the present embodiment, the connecting end 2023 of the first locking ring 202 can also be connected with the second locking ring 203 through insertion, clamping, bonding or the like.

[0082] Embodiment 4

[0083] In the fourth implementation, as shown in Figure 3 , the insertion end 103 is provided with a hollow area 1032, and the hollow area 1032 makes the insertion end 103 form a first arm 1031 with one end suspended, and the abutting segment 102 is arranged on the outer circumferential surface of the movable end of the first arm 1031. In this way, the first arm 1031 forms an elastic force arm, so that in the process of disassembling and assembling the stylus tip 1, the elastic deformation of the first arm 1031 drives the abutting segment 102 to move, thereby facilitating the change of the relative position of the limiting segment 201 and the abutting segment 102, and after assembly is completed, the first arm 1031 drives the abutting segment 102 to reset, realizing abutting and limiting.

[0084] It should be noted that in the present embodiment, the abutting segment 102 and the limiting segment 201 can both be rigid structures, for example, metal materials. That is, the abutting segment 102 or the limiting segment 201 does not need to be deformed.

[0085] Of course, as an alternative implementation, the limiting segment 201 and / or the abutting segment 102 can also be provided as an elastic structure, that is, the limiting segment 201 and / or the abutting segment 102 are made of deformable elastic materials, such as rubber, elastic plastic or the like. Specifically, only the abutting segment 102 can be an elastic structure, in which case the limiting segment 201 is a rigid structure; or only the limiting segment 201 is an elastic structure, in which case the abutting segment 102 is a rigid structure; or both the abutting segment 102 and the limiting segment 201 are elastic structures.

[0086] Further, in the present embodiment, as shown in Figure 9 , Figure 10 , the pen body assembly includes a pen barrel 2, a first locking ring 202, the first locking ring 202 being located in the pen barrel 2, and the limiting segment 201 being located on the inner circumferential wall of the limiting end 2022 of the first locking ring 202.

[0087] Further, in the present embodiment, as shown in Figure 9 , Figure 10As shown, the pen body assembly also includes a second locking ring 203 and a conductive refill 3. The second locking ring 203 is located within the pen barrel 2. One end of the first locking ring 202 is a connecting end 2023, and the other end is a limiting end 2022. The internal thread 2021 of the connecting end 2023 is threadedly connected to the external thread 2031 of the second locking ring 203. The limiting section 201 is provided on the inner circumferential wall of the limiting end 2022. The limiting end 2022 is adapted to accommodate the insertion end 103 of the stylus tip 1. The second locking ring 203 is fixedly disposed within the pen barrel 2. By providing the limiting section 201 on the first locking ring 202, the limiting section 201 does not need to be disposed within the pen barrel 2, effectively reducing the difficulty of producing the pen barrel 2 while ensuring the limiting effect on the stylus tip 1.

[0088] It is worth noting that the second locking ring 203 can be fixedly connected to the pen barrel 2 , or the second locking ring 203 can be fixedly connected to other components with fixed positions in the pen barrel 2 .

[0089] It should be noted that, in the embodiment, the first locking ring 202 and the second locking ring 203 are both made of metal (eg, brass, stainless steel, etc.). This arrangement can enhance the structural strength of the pen barrel 2 and the conductive refill 3 .

[0090] It should be noted that the insertion end 103 of this embodiment is as follows Figure 3 、 Figure 9 As shown, at least two hollow areas 1032 are opened along the circumference of the insertion end 103 to form at least two first arms 1031 , and an abutting section 102 is correspondingly provided on the outer periphery of the suspended end of each first arm 1031 .
