Description

[Technical field]

[0001] The present invention is in the technical field of styli, and more particularly relates to styli. [Background technology]

[0002] The tip of the tip of the conventional electronic stylus is a fixed design, and the touch screen has a hard structure, so when the electronic stylus is used to slide across the touch screen, the touch screen does not deform like paper, and the tip of the tip of the conventional stylus does not displace in the axial direction of the stylus, so the tip of the tip of the tip of the conventional stylus makes strong contact with the touch screen, which makes the user feel that it is hard to touch, that is, this touch is completely different from the touch of using a conventional pen to write on paper, resulting in a poor user experience. Therefore, in order to provide users with a good writing experience, it is generally necessary to provide the tip of the tip of the stylus with the ability to move along the axial direction of the stylus, but how to maintain electrical connection during the tip of the tip's displacement process is an issue that needs to be resolved immediately. Summary of the Invention [Problem to be solved by the invention]

[0003] In order to solve the above technical problems, the present invention discloses a stylus in which a signal pin is slidably and electrically connected to a conductive member in the axial direction of the stylus, thereby providing a user with a true writing experience during the user's use and ensuring that a precisely positioned touch operation can be obtained on the touchpad. [Means for solving the problem]

[0004] The specific technical proposal of this invention is as follows:

[0005] A stylus, a body having a chamber at an end, the chamber including a conductive member extending axially along the body; a signal pin slidably and electrically connected to the conductive member within the chamber, the signal pin having one end extending from the body for touching the touch screen to collect a signal; and an elastic member disposed between the signal pin and the body.

[0006] The signal pin at the front end of the pen tip is used to touch the touch screen, when the user uses the pen tip to engage with the touch screen, the signal pin slides on the touch screen to realize the control of the touch screen, and because there is an elastic member between the signal pin and the body, the signal pin can slide relative to the body, thus simulating the traditional pen and paper writing experience. The signal pin can directly collect signals, so that the signal pin and the touch screen are in contact during the user's use process, and the distance between them is kept the same, in other words, the signal collection distance of the signal pin is constant, so that the user can smoothly hold the handwritten strokes during the touch process.

[0007] Preferably, one end of the signal pin protruding from the main body is covered with a touch head cover.

[0008] The touch head cover can prevent the signal pin from scratching the touch screen, and provide a vibration damping effect for the signal pin when it contacts the touch screen, thereby providing better structural reliability for the pen tip.

[0009] Preferably, the touch head cover includes a covering portion and an elastic deformation portion, the covering portion is used to cover one end of the signal pin protruding from the main body, the elastic deformation portion contacts the main body, and when the signal pin slides relative to the conductive member, the elastic deformation portion deforms in the axial direction of the main body.

[0010] The elastic deformation portion can provide a better damping sensation for the user, thereby forming a better soft contact between the stylus and the touch screen according to the elastic member, allowing the user to experience a writing feel closer to that of traditional pen and paper.

[0011] Preferably, the covering portion has a thickness greater than a thickness of the elastically deformable portion.

[0012] Since the thickness of the elastic deformation part is smaller than the thickness of the covering part, during actual use by the user, the elastic deformation part preferentially deforms along the axial direction of the main body, and the covering part only maintains flexible contact with the touch screen.

[0013] Preferably, the covering portion has a spherical contact surface for contacting the touch screen.

[0014] The spherical contact surface allows the user to hold the pen at multiple angles, ensuring that the same writing effect can be achieved in every direction and angle.

[0015] Preferably, the end surface of one end of the signal pin extending from the body has a spherical structure, and the contact spherical surface and the spherical structure are concentric and have different diameters.

[0016] In order to ensure that the signal pin can obtain a stable signal from each direction when the user uses the stylus, on the basis of ensuring that the signal pin can obtain a signal within a corresponding distance, the distance from any two points of the spherical structure to the contact spherical surface is made equal, so that the user has a stable signal in the process of using the stylus, and each position of the covering part has consistent vibration suppression ability, thereby better improving the user's usage experience.

[0017] Preferably, the conductive member is provided with a stopper portion at one end along which the signal pin moves in the axial direction, and the elastic member is provided between the stopper portion and the signal pin.

[0018] The stopper portion can provide a mounting position for the elastic member, thereby meeting the deformation requirement of the elastic member, and thus providing a good usage feeling for the user.

[0019] Preferably, the elastic member is provided between the stopper portion and the end of the signal pin, or The pin body of the signal pin is provided with a support portion along its circumferential direction, and the elastic member is provided between the support portion and the stopper portion.

[0020] When the elastic member is provided between the stopper portion and the end of the signal pin, the pin body portion of the signal pin is slidably and electrically connected to the conductive member, and when the pin body of the signal pin is provided with a support portion along its circumferential direction, the diameter of the support portion is larger than the diameter of the pin body portion of the signal pin, and thus the signal pin is slidably and electrically connected to the conductive member via the support portion.

[0021] Preferably, when the elastic member is provided between the stopper portion and the end of the signal pin, the conductive member has a sleeve-like structure with one end open and one end closed, the elastic member is provided between the closed end of the conductive member and the end of the signal pin, and a first position limiting portion is provided at the open end of the conductive member, and is used to prevent the signal pin from continuing to slide toward the outside of the chamber at the position of the first position limiting portion; When the pin body of the signal pin is provided with a support portion along its circumferential direction, the conductive member has a sleeve-like structure with both ends open, one open end of the conductive member is provided with a second position limiting portion, the elastic member is provided between the support portion and the second position limiting portion, and the other open end of the conductive member is provided with a first position limiting portion, which engages with the support portion to prevent the signal pin from continuing to slide toward the outside of the chamber at the position of the first position limiting portion.

[0022] The above structure is simple and practical, and can meet not only the requirement of slidable and electrical connection between the signal pin and the conductive member, but also the assembly requirement of the elastic member.

[0023] Preferably, the body and the conductive member are removably connected, or The body is integrally formed with the conductive member by injection molding.

[0024] Both of the above two connection methods can realize the assembly connection between the body and the conductive member.

[0025] Preferably, when the body is integrally formed with the conductive member by injection molding, one of the chamber and the conductive member is provided with a support bump, and the other is provided with a support groove that engages with the support bump.

[0026] The engagement between the support bump and the support groove can provide better connection stability between the integrally injection-molded body and the conductive member, and can prevent the two from loosening or falling off, thereby better extending the service life and meeting the usage requirements of users.

[0027] Preferably, the touch head cover is made of a flexible material.

[0028] Because the touch head cover is made of flexible material, it can better realize the buffering between the stylus and the touch screen, so as to better protect the touch screen from being scratched.

[0029] Preferably, the resilient member is made from a conductive metallic material.

[0030] Since the signal pin and the conductive member are in a slip-fit ​​relationship, it is inevitable that a gap will occur between the signal pin and the conductive member, so that after the elastic member is made of a conductive metal material, the stability of the electrical connection between the signal pin and the conductive member can be improved. Compared with the prior art, in this invention, the signal pin contacts the touch screen and the signal reception is maintained by the signal pin within a certain distance range, and in the process of use, no matter how the signal pin moves along the axial direction of the body, the distance does not change, so as to ensure the user's usage experience. The invention simulates the writing experience of traditional pen and paper through the elastic member, and the cooperation of the elastic deformation part makes the user's writing experience better.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] In order for those skilled in the art to better understand the technical solutions in the present invention, the present invention will be described in more detail below in combination with specific embodiments.

[0033] Example 1 This embodiment is applied to a stylus, which includes a body and an elastic pen tip 100, and the elastic pen tip 100 is connected to the body. The body is generally a cylindrical structure, and may of course be a polygonal structure or a combination structure of a cylinder and a polygonal structure, which is used to make it easier for users to hold, and the side of the polygonal structure may be one side. In one technical solution, the body and the elastic pen tip 100 may be an integrally provided whole structure, that is, the body and the elastic pen tip 100 are not detachable, and in another technical solution, the body and the elastic pen tip 100 are detachably connected, and may be snap-connected or screwed, and generally, in order to ensure the connection stability between the body and the elastic pen tip 100, the body and the elastic pen tip 100 are usually assembled in a screwed manner.

[0034] As shown in Figures 1 to 4, in this embodiment, the elastic pen tip 100 is an elastic pen tip 100 of an electronic stylus, and includes a body 1, a signal pin 2, and an elastic member 3, the body 1 has a chamber at its end, a conductive member 4 extending along the axial direction of the body 1 is provided within the chamber, the signal pin 2 is slidably and electrically connected to the conductive member 4 within the chamber, one end of the signal pin 2 protrudes from the body 1 and is used to touch a touch screen and collect signals, and the elastic member 3 is provided between the signal pin 2 and the body 1. It can be understood that when a user uses the stylus, the elastic member 3 deforms in the axial direction of the stylus, and the signal pin 2 expands and contracts at the opening of the chamber. In this case, the signal pin 2 slides axially through the conductive member 4 to be restricted in position, and electrical connection is realized by the sliding. That is, the conductive member 4 and the signal pin 2 are both made of conductive metal material. In some technical solutions, after the assembly of the elastic pen tip 100 and the body is completed, the conductive member 4 realizes circuit conduction with the power supply unit of the body. Therefore, when the signal pin 2 is electrically connected to the conductive member 4 by sliding, the circuit is also conducted to the signal pin 2. In another technical solution, the elastic member 3 is also made of conductive metal material. The elastic member 3 is made of conductive metal material, and as can be seen, in order to ensure that there is a smooth and interference-free relative sliding between the signal pin 2 and the conductive member 4, there is a clearance fit between the signal pin 2 and the conductive member 4, and when the clearance between them is very small and the processing precision is very high, such clearance can be ignored, but in the process of the signal pin 2 sliding relative to the conductive member 4, there is still a slight possibility that the circuit between the signal pin 2 and the conductive member 4 will be cut off, so if the elastic member 3 is also made of conductive metal material, it can ensure that the circuit between the conductive member 4 and the signal pin 2 is always conductive, which better meets the actual use needs. As explained, the conductive member 4 extends from one end of the chamber to the other end of the chamber, that is, the conductive member 4 completely covers the sliding path of the signal pin 2, which better meets the requirements of slidability and electrical connection.

[0035] As shown in Figs. 1 to 3, in this embodiment, one end of the signal pin 2 protruding from the body 1 is covered with a touch head cover 5. The touch head cover 5 is made of a flexible material. Furthermore, the touch head cover 5 includes a covering portion 501 and an elastically deforming portion 502, the covering portion 501 is used to cover one end of the signal pin 2 protruding from the body 1, the elastically deforming portion 502 contacts the body 1, and when the signal pin 2 slides relative to the conductive member 4, the elastically deforming portion 502 deforms in the axial direction of the body 1. The transition part 503 is connected between the covering part 501 and the elastic deformation part 502. When the covering part 501 contacts the touch screen, the user's writing strength cannot always be kept consistent, so that a relative slide occurs between the signal pin 2 and the conductive member 4, and one end of the signal pin 2 for receiving a signal is the pin head. In this case, the relative distance between the pin head and the main body 1 is reduced, and the elastic deformation part 502 is compressed, so that the movement direction of the pin head is maintained only along the axial direction of the stylus. Therefore, most of the skewed pressing force can be transferred from the covering part 501 to the elastic deformation part 502 by the transition part 503, so as to better meet the cooperation between the elastic member 3 and the elastic deformation part 502. In order to better meet the deformation requirements of the elastic deformation part 502 and avoid the over-compression of the covering part 501 affecting the signal acquisition by the pin head, the thickness of the covering part 501 is greater than the thickness of the elastic deformation part 502. That is, when the elastic deformation part 502 is deformed or compressed, the deformation of the covering part 501 is very small or non-existent, thereby satisfying the stable signal reception of the pin head.

[0036] As shown in Fig. 3, in this embodiment, the covering part 501 has a contact spherical surface for contacting the touch screen. Furthermore, the end surface of one end of the signal pin 2 protruding from the body 1 is a spherical structure, and the distances from any two points of the spherical structure of the pin head to the contact spherical surface are the same. When a user writes on a touch screen, a certain inclination angle is generally formed between the body and the touch screen, so that the inclination angle when different users use a stylus needs to be met. On this basis, firstly, the signal receiving ability of the pin head is met, and then the distance requirement between the contact spherical surface and the spherical structure is met. Therefore, as can be understood, between the contact spherical surface and the spherical structure, the arc surfaces of both can be concentric and have different diameters.

[0037] In this embodiment, the conductive member 4 is provided with a stopper portion at one end where the signal pin 2 moves in the axial direction, and the elastic member 3 is provided between the stopper portion and the signal pin 2. Specifically, the elastic member 3 is provided between the stopper portion and the end of the signal pin 2. In this case, the conductive member 4 has a sleeve-like structure with one end open and one end closed, and the elastic member 3 is provided between the closed end of the conductive member 4 and the end of the signal pin 2. A first position limiting portion 6 is provided at the open end of the conductive member 4, and is used to prevent the signal pin 2 from continuing to slide toward the outside of the chamber at the position of the first position limiting portion 6. In this case, the stopper portion is the end of the closed end of the conductive member 4. The elastic member 3 is a spring. 4, in this embodiment, the pin body of the signal pin 2 can be regarded as a stepped structure, and has a large diameter pin body and a small diameter pin body, so that the large diameter pin body is slidably and electrically connected to the conductive member 4, and the small diameter pin body is slidably and electrically connected to the open end formed by the first position limiting part 6, whereby the large diameter pin body and the first position limiting part 6 form a motion interference, so as to prevent the signal pin 2 from sliding out of the body 1 due to this point. As described herein, the spring can be a compression spring or a tension spring, and the installation distinction is only that the springs are on different ends of the conductive member 4, and will not be described here.

[0038] In this embodiment, the body 1 is integrally formed with the conductive member 4 by injection molding. If the outer side of the conductive member 4 has an optical axis structure, the connection stability between the conductive member 4 and the body 1 is somewhat poor. Therefore, in this embodiment, one of the chamber and the conductive member 4 is provided with a support bump 7, and the other is provided with a support groove that engages with the support bump 7. Specifically, as shown in Figures 1 to 3, in a preferred embodiment, the chamber is provided with an annular support groove, and the conductive member 4 is provided with an annular support bump 7, and the number of the support bumps 7 in the axial direction of the body 1 is at least one, and of course, as should be understood, the number of the support grooves is the same as the number of the support bumps 7 and corresponds to each other. As a result, the positional restriction for the conductive member 4 in the axial direction is realized by the body 1, which better meets the structural stability requirements.

[0039] Example 2 Compared with Example 1, this embodiment is distinguished by a different installation method of the elastic member 3. The pin body of the signal pin 2 is provided with a support portion 8 along its circumferential direction, and the elastic member 3 is provided between the support portion 8 and the end face of the conductive member 4. Furthermore, the conductive member 4 has a sleeve-like structure with both ends open, and a second position limiting portion 9 is provided at one open end of the conductive member 4. The elastic member 3 is provided between the support portion 8 and the second position limiting portion 9, and a first position limiting portion 6 is provided at the other open end of the conductive member 4, which is engaged with the support portion 8 and is used to prevent the signal pin 2 from continuing to slide toward the outside of the chamber at the position of the first position limiting portion 6. In this embodiment, one end of the elastic member 3 is connected to the support portion 8, and the outer surface of the support portion 8 is slidably and electrically connected to the conductive member 4, while the portion between the pin head and the support portion 8 is slidably and electrically connected to the opening formed at the first position limiting portion 6.

[0040] In order to realize the extrapolation of the elastic member 3, generally, the pin body part of the signal pin 2 protrudes from the support part 8, so that the installation manner of the second position limiting part 9 is different in different technical solutions. In one technical solution, as shown in FIG. 5, when the protruding part is short, there is a large stroke distance between the end of the signal pin 2 and the corresponding end of the conductive member 4, so that the second position limiting part 9 forms a blockage of the corresponding open end; in another technical solution, as shown in FIG. 6, the protruding part is long, and the second position limiting part 9 forms a structure similar to the first position limiting part 6, in this case, the protruding part can realize sliding with the open end formed at the second position limiting part 9, in this case, the position limit for the axial movement of the signal pin 2 can also be realized by such a connection manner. As can be seen, in the above technical solution, the stopper part is constituted by the second position limiting part 9.

[0041] Example 3 The present embodiment is distinguished from the above-mentioned embodiments in that the connection method between the main body 1 and the conductive member 4 is different. In the present embodiment, the main body 1 and the conductive member 4 are removably connected, and specifically, may be a screw-fit or engagement connection, etc.

[0042] When the engagement connection method is used, the connection of the engagement connection part is easily unstable, and such instability is caused by deformation during the removal process and the supporting action during the writing process, so that if the user uses it for a long time, there is a possibility that the main body 1 and the conductive member 4 will have a rocking motion, therefore, if the connection between the main body 1 and the conductive member 4 is a detachable connection method, it is preferable that the main body 1 and the conductive member 4 are screwed together. In this case, as shown in FIG. 7, a straight hole 10 or a cross hole is processed on the outside of the first position limiting part 6 of the conductive member 4, that is, a straight screwdriver or a cross screwdriver can be used to attach and detach the conductive member 4 to the main body 1, thereby realizing a detachable connection between the two.

[0043] The above is merely a preferred embodiment of the present invention, and the above preferred embodiment should not be considered as a limitation on the present invention, and the protection scope of the present invention should be based on the scope defined by the claims. Those skilled in the art may make some improvements and modifications without departing from the spirit and scope of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
