[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] As a kind of electronic device, the electromagnetic radiation generated by the stylus (also known as electronic pen) during use is an issue that cannot be ignored. Electromagnetic radiation may not only affect the performance and stability of the stylus itself, but also pose potential risks to other electronic devices around it. Therefore, electromagnetic protection of the stylus is particularly important. In the related art, in order to achieve electromagnetic protection of the stylus, the following two methods are usually used. First, most areas of the pen holder are made of plastic, and other areas are made of metal, and then spliced ​​and formed. The electromagnetic components inside the stylus are arranged on the metal part of the pen holder to achieve the effect of electromagnetic shielding. Second, the entire pen holder is made of plastic material, and conductive cloth or metal rings and other structures are arranged in the stylus to achieve the effect of shielding interference. In order to improve the comfort of using the stylus and facilitate the user to accurately control the position of the pen tip, the shape of the pen head is usually designed to be similar to a cone. However, this also makes it difficult to prepare the pen head and the pen body at the same time. In the related art, the pen head and the pen body are usually prepared by forming and assembling the pen body separately.

[0039] The applicant has discovered that if the pen holder is prepared by first splitting it and then splicing it together, there will be gaps at the joints, especially at the joints between the pen tip and the pen body. To facilitate communication between the stylus and the touch screen, the electromagnetic components inside the stylus are usually arranged at one end close to the pen tip. If there is a gap at the joint between the pen tip and the pen body, the electromagnetic shielding of the stylus will fail, and even the electromagnetic information of the stylus will be leaked. In addition, this preparation method has many steps, and in order to ensure that the pen tip can be effectively connected to the pen body, it is necessary to increase the preparation accuracy requirements of the pen tip and the pen body, which is not conducive to improving the production efficiency of the stylus.

[0040] If the pen holder is made of plastic, and conductive cloth or metal rings are installed inside the stylus to achieve the electromagnetic shielding effect of the stylus, the size of the stylus will increase, which is not conducive to the user experience. In addition, structures such as conductive cloth or metal rings are difficult to assemble on the pen holder, and conductive cloth or metal rings will also affect the assembly of other components inside the stylus, making the stylus difficult to assemble and the production cycle long. In addition, other components inside the stylus may rub against the conductive cloth (or metal ring) during the assembly process on the pen holder, causing damage to other components or the conductive cloth.

[0041] For this reason, please see Figures 1 to 3 The utility model proposes a pen holder 100 suitable for a stylus pen 10. The material of the pen holder 100 is selected to have electromagnetic shielding properties. The pen holder 100 includes a pen body 110 and a pen tip 120. The pen body 110 extends along a first direction X. The pen tip 120 is located at one end of the pen body 110 along the first direction X, and the inner diameter of the pen tip 120 gradually decreases along the first direction X, so that the pen tip 120 can guide the electromagnetic components inside the stylus pen 10 so that the signals emitted by it can effectively act on the touch screen. In one embodiment, the outer diameter of the pen tip 120 gradually decreases along the first direction X, that is, the pen tip 120 is set to a cone-like structure with equal wall thickness. The pen tip 120 can be used to install a pen tip 200, and the pen tip 200 can act on the touch screen. The pen holder 100 can provide protection for the components inside the stylus pen 10. In the present application, the pen tip 120 and the pen body 110 are integrally formed, and the forming methods of the pen tip 120 and the pen body 110 include but are not limited to die casting, extrusion, etc. There is no gap at the connection between the pen tip 120 and the pen body 110, and both the pen tip 120 and the pen body 110 have electromagnetic shielding properties, so the electromagnetic shielding effect of the pen holder 100 of the present application is better, which can effectively reduce the risk of electromagnetic information leakage of the stylus 10 during operation. In addition, the manufacturing method of integrally forming the pen tip 120 and the pen body 110 eliminates the reconnection process of the pen tip 120 and the pen body 110, effectively improving the preparation efficiency of the pen holder 100, and further improving the production efficiency of the stylus 10.

[0042] The materials selected for the pen body 100 include but are not limited to metal shielding materials, metal oxide shielding materials, and conductive polymer shielding materials.

[0043] See also Figure 3In one embodiment, the pen body 110 and the pen tip 120 jointly define a receiving chamber 111, and the end of the pen tip 120 away from the pen body 110 has a first opening 121, and the first opening 121 is connected to the receiving chamber 111. The pen tip 200 is installed in the receiving chamber 111 and protrudes from the pen tip 120 through the first opening 121, so that the pen tip 200 can effectively act on the touch screen. Among them, along the first direction X, the size of the part of the pen tip 200 protruding from the pen tip 120 is smaller than the size of the pen tip 120. The probability of the pen tip 200 shaking or deflecting during use of the stylus 10 due to excessive protrusion of the pen tip 200 from the pen tip 120 is reduced, and the stability of the pen tip 200 when moving on the touch screen is improved. It also helps to improve the user's comfort and reduce hand fatigue. The design that the dimension of the pen tip 200 protruding from the pen head 120 along the first direction X is smaller than the dimension of the pen head 120 along the first direction X is more ergonomic, can improve the user's control accuracy of the contact point between the stylus 10 and the touch screen, and reduce the probability of false touches.

[0044] The pen holder 100 is provided with a control module 300. The control module 300 is configured to be able to communicate with the touch screen. The control module 300 is arranged in the accommodating cavity 111, and the projection formed by the pen holder 100 on the radial projection surface perpendicular to the accommodating cavity 111 covers the projection formed by the control module 300 on the projection surface. The setting of the control module 300 increases the functions of the stylus 10. The control module 300 can recognize functions such as pressure sensing, tilt sensing, and gesture recognition and manage these functions to ensure that each function is activated and executed in the right way at the right time. The control module 300 is provided with components such as sensors and wireless communication modules. The design that the projection formed by the pen holder 100 on the radial projection surface perpendicular to the accommodating cavity 111 covers the projection formed by the control module 300 on the projection surface can effectively reduce the probability of leakage of electromagnetic signals generated by the control module 300, and can also effectively improve the anti-electromagnetic interference capability of the stylus 10.

[0045] Specifically, see Figure 3 , the pen body 100 is provided with a first electrode 400, a second electrode 500 and a control module 300, the control module 300 is configured to be able to communicate with the touch screen, the control module 300 is arranged in the accommodating cavity 111, the first electrode 400 is connected to the control module 300, and the first electrode 400 is arranged in the first opening 121 and protrudes from the pen head 120. The second electrode 500 is arranged in the accommodating cavity 111 and connected to a side of the control module 300 away from the first electrode 400. In one embodiment, the first electrode 400 is configured to be able to send a signal to the touch screen or receive a signal sent by the touch screen. In another embodiment, the first electrode 400 is configured to be able to both receive a signal sent by the touch screen and send a signal to the touch screen, thereby realizing the communication between the stylus 10 and the touch screen.

[0046] It should be noted that when the first electrode 400 acts on the touch screen, a coupling capacitor is formed between the human body electric field, the stylus 10 and the surface of the touch screen. For high-frequency current, the first electrode 400 can act as a conductor to guide a tiny current to flow out from the contact point between the stylus 10 and the touch screen. The current flows through multiple electrodes arranged on the touch screen, and the current flowing through each electrode is proportional to the distance from the stylus 10 to each electrode. By calculating the ratio of the current flowing through each electrode, the position information of the stylus 10 in contact with the touch screen can be obtained. The second electrode 500 can be used to balance the current when the stylus 10 interacts with the touch screen to ensure the stability of the current flow. The second electrode 500 can also be used as a reference electrode, which can be used to calibrate and compare the signal received from the touch screen. The second electrode 500 can improve the positioning accuracy and response speed of the stylus 10 and reduce errors and deviations by cooperating with the first electrode 400. In addition, the second electrode 500 can also be used to sense electromagnetic interference from outside the pen 100, detect the anti-electromagnetic interference capability of the pen 100, and output the sensed electromagnetic interference information from outside the pen 100 to the control module 300, and perform filtering and other processing by the control module 300, thereby improving the stability and reliability of the stylus 10. The second electrode 500 can also interact with sensors or other components inside the stylus 10, thereby increasing the functions of the stylus 10 (such as pressure sensing, tilt sensing, etc.). Exemplarily, in the pressure sensing function of the stylus 10, the second electrode 500 can be used as part of the pressure sensor, or it can be connected to the pressure sensor. When the pressure sensor detects a pressure change, the second electrode 500 can transmit the pressure change to other components or the control module 300 in the form of an electrical signal. The control module 300 processes and analyzes the electrical signal, determines the size and change of the pressure, and adjusts the output of the stylus 10.

[0047] See also Figure 1, the pen shaft 100 is provided with a notch 113, the notch 113 is located on the peripheral side of the pen body 110, and the notch 113 is arranged on the side of the second electrode 500 away from the first electrode 400 along the first direction X, and the notch 113 is suitable for installing a button. The setting of the notch 113 can provide an interactive window between the button and the internal components of the stylus 10, which is conducive to increasing the function of the stylus 10 and improving the user experience. The setting position of the notch 113 is far away from the setting position of the first electrode 400 and the second electrode 500, which can effectively reduce the possibility of electromagnetic signal leakage of the first electrode 400 and the second electrode 500 during the operation of the stylus 10. In some embodiments, a plane perpendicular to the radial direction of the accommodating cavity 111 is defined as a projection plane, and the projection formed by the notch 113 on the projection plane is spaced from the projection formed by the control module 300 on the projection plane. Specifically, the notch 113 on the pen body 100 is located away from the control module 300 in the accommodating cavity 111 , so that the electromagnetic signal generated by the control module 300 can always be blocked by the pen body 110 , thereby preventing the electromagnetic signal from leaking to the outside through the notch 113 .

[0048] In one embodiment, the pen body 100 has a second opening 112, and the second opening 112 is arranged opposite to the first opening 121 along the first direction X. The button can be arranged on the stylus pen 10 through the second opening 112, thereby reducing the risk of electromagnetic signal leakage inside the stylus pen 10 and further improving the anti-electromagnetic interference capability of the pen body 100. In another embodiment, the second opening 112 is arranged at the end of the pen body 110 away from the pen head 120, which is also conducive to the assembly of the internal components of the stylus pen 10, that is, the internal components of the stylus pen 10 can be placed in the accommodating cavity 111 through the second opening 112.

[0049] The pen holder 100 includes a pen body 110 and a pen tip 120, wherein the shape of the side of the pen body 110 away from the receiving cavity 111 may be a polygon. Specifically, the outer contour of the pen body 110 along the cross section perpendicular to the axis of the receiving cavity 111 may be a polygon such as a triangle or a quadrilateral, or may be a circle or other arc-shaped shapes. In one embodiment, along the first direction X, the maximum dimension of the pen body 110 in the direction parallel to the radial direction of the receiving cavity 111 is equal everywhere. For example, see Figure 1 , the outline of the pen body 110 may be cylindrical. In another embodiment, along the first direction X, the maximum size of the pen body 110 in a direction parallel to the radial direction of the accommodating cavity 111 may be different. Exemplarily, the pen body 110 may be a conical structure with a gradually decreasing diameter along the first direction X, and the outline of the pen body 110 may also be a shape similar to a bamboo joint.

[0050] The pen tip 120 includes an extension section and a transition section. The extension section is truncated. One end of the transition section is connected to the pen body 110 and the other end is connected to the extension section. The maximum size of the transition section in the radial direction of the accommodating cavity 111 gradually decreases along the direction from the pen body 110 to the extension section. The outer contour of the projection formed by the end of the transition section close to the pen body 110 on the projection plane perpendicular to the first direction X is the same as the outer contour of the projection formed by the pen body 110 on the projection plane. The outer contour of the projection formed by the bottom end of the transition section close to the extension section on the projection plane is the same as the outer contour of the projection formed by the end of the extension section close to the transition section on the projection plane. The pen tip 200 is arranged in the accommodating cavity 111 and passes out from the end of the extension section away from the transition section. The setting of the transition section is conducive to avoiding stress concentration between the extension section and the pen body 110, improving the service life of the pen holder 100 and improving the aesthetics of the pen holder 100.

[0051] In some embodiments, the maximum diameter of the extension section is smaller than the minimum dimension of the pen body 110 in the radial direction of the accommodating cavity 111, and the dimension of the extension section along the first direction X is smaller than the dimension of the transition section along the first direction X. Thus, the provision of the transition section can reduce the size difference between the pen body 110 and the extension section, and further avoid stress concentration between the pen body 110 and the pen tip 120.

[0052] The forming method of the pen holder 100 is as follows, and the forming method of the pen holder 100 can be used to manufacture the pen holder 100 described in any of the above embodiments. The forming method of the pen holder 100 includes but is not limited to the following steps:

[0053] Prepare materials, which include but are not limited to metal shielding materials, metal oxide shielding materials, and conductive polymer shielding materials. For ease of description, the following description takes metal materials as an example.

[0054] In one embodiment, the metal material is extruded to obtain the pen body 110 ; in another embodiment, the metal material is stretched to obtain the pen body 110 .

[0055] The pen tip 120 is manufactured by spinning one end of the pen body 110 along the first direction X.

[0056] In another embodiment, the pen tip 120 may also be manufactured by stamping one end of the pen body 110 along the first direction X.

[0057] Compared with the lathe processing and forming in the related art, the forming method of the pen holder 100 provided in the present application has a more flexible appearance design of the pen holder 100. In order to facilitate the splicing of the pen tip and the pen body and the aesthetics after splicing, the pen body in the related art is usually designed to be cylindrical, so the related art usually adopts extrusion molding combined with external cylindrical grinding and other processes to manufacture the pen body. In the present application, the pen tip 120 and the pen body 110 can ensure integrity during the manufacturing process, so there is no need to consider the splicing of the pen tip 120 and the pen body 110, and the appearance of the pen body 110 can be designed as needed (for example, the outer contour cross-sectional shape of the pen body 110 can be designed as a trapezoid, an irregular polygon, etc.). In addition, the pen holder 100 prepared by the molding method of the pen holder 100 provided in the present application uses the same material for the pen body 110 and the pen tip 120. Compared with the related art in which the pen tip is spliced ​​to the pen body, the pen holder 100 has better reliability and can effectively reduce the probability of the pen tip 120 being separated from the pen body 110 when the stylus 10 falls or is impacted (in the related art, the pen tip is spliced ​​to the pen body, and even the pen body is also spliced ​​with multiple sections. When the stylus falls or is impacted, the stress at the joints between the pen tip and the pen body and the various sections of the pen body increases dramatically, which is likely to cause the pen tip to separate from the pen body and the various sections of the pen body to separate).

[0058] On the other hand, the forming method of the pen holder 100 proposed in the present application eliminates the process of splicing the pen head and the pen body in the related art, effectively improves the production efficiency of the pen holder 100, and is conducive to the mass production of the stylus pen 10.

[0059] In one embodiment, the forming method of the pen holder 100 further includes the following steps: the blank obtained after the preparation of the pen body 110 and the pen tip 120 can be processed by CNC (numerical control machine) to shape the portion of the pen body 110 close to the pen tip 120 and (or) the portion of the pen body 110 at one end away from the pen tip 120 and (or) the portion of the pen body 110 located at the pen tip 120 and the end away from the pen tip 120, so that the shape of the pen holder 100 meets the needs of customers. In another embodiment, the shaping of the pen holder 100 can also be processed by a spinning process.

[0060] In addition, after the pen tip 120 and the pen body 110 are prepared, the molding method of the pen shaft 100 may also include the steps of: using CNC (numerical control machine tool) or other equipment to shape, deburr, etc. the first opening 121 located at the end of the pen tip 120 away from the pen body 110 and the second opening 112 located at the end of the pen body 110 away from the pen tip 120, and groove the pen body 110 so that the pen body 110 has a groove 113 for installing a button.

[0061] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0062] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features.

Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
