Technical Field

The application relates to the technical field of electronic touch equipment, in particular to a touch pen and an electronic equipment device.

Background

The stylus typically monitors the force applied to the nib by a pressure sensor to identify whether the stylus is in a writing mode or not and how much force is being written during writing.

The pressure sensor has high requirements on the use environment, and under relatively extreme environmental conditions such as high temperature, low temperature or vibration, the measurement accuracy of the pressure sensor is easily affected and even can lose functions.

And unexpected situations such as falling and the like can not be avoided in the using process of the touch pen, and if the pressure sensor can not be effectively protected under the situation, the performance of the pressure sensor can be influenced. Thus, in order to prevent the pressure sensor from being damaged by a large impact force and even prevent the stylus from being used normally, a buffering scheme is required to be designed for the pressure sensor.

At present, a common buffering scheme is to add an elastic element connected with the pressure sensor, so that impact energy acting on the pressure sensor when falling is absorbed by the elastic element to realize buffering.

For example, a silica gel pad is additionally arranged at the rear of the pressure sensor, so that impact force acting on the pressure sensor when falling is buffered by the silica gel pad. However, the silica gel pad has obvious deformation and denaturation risks under the high-temperature and high-humidity environment, and the elastic force and the initial size cannot be continuously maintained, so that the silica gel pad cannot continuously act on the buffer of the pressure sensor.

Example 1

Referring to fig. 1 and 2 in conjunction with fig. 3 and 4, embodiments of the present application provide a stylus 1, where the stylus 1 is configured to implement interaction with an electronic device of an electronic device apparatus in a touch manner, and specifically, the stylus 1 contacts the electronic device, so as to implement writing on the electronic device by the electronic device.

The stylus 1 comprises a nib 10, a spring needle electrode 11 and a connecting sleeve 12, wherein a containing cavity is formed in the nib 10, so that the nib 10 is of a conical shell structure and is provided with a tip, and the nib 10 is contacted with an electronic device through the tip.

The spring needle electrode 11 includes a stop portion 112, a spring needle and an electrode 111, the spring needle has a fixed end and an elastic end which are opposite to each other, the elastic end is elastically connected with the fixed end, the elastic end can stretch and retract in a direction opposite to the direction of the elastic end and the fixed end under the elastic action, the elastic end is used as an elastic contact for directly or indirectly abutting against the pressure sensor 15, and the impact force transmitted by the stylus 1 to the pressure sensor 15 is converted into elastic potential energy that the elastic end stretches and contracts elastically relative to the fixed end, so that the impact force received by the pressure sensor 15 is buffered.

The electrode 111 is generally used as a first emitter electrode 111 of the stylus 1 and is used together with a second emitter electrode 145, and the first emitter electrode 111 and the second emitter electrode 145 are at least used for sending signals to an electronic device, so that the electronic device can determine information such as a writing angle and a writing position of the stylus 1.

The electrode 111 is connected with the fixed end into a whole, so that the electrode 111 and the spring needle are used as a whole, and compared with the scheme of split arrangement of the electrode 111 and the spring needle, the positioning scheme of the electrode 111 and the spring needle in the pen point 10 is beneficial to simplification, and the positioning precision of the electrode 111 and the spring needle relative to the pen point 10 is improved.

The stop 112 is connected to the outer wall of the spring needle, i.e. the stop 112 may for example have a convex shape relative to the outer wall of the spring needle. Optionally, the stop 112 is integrally formed with the spring needle, thereby reducing the difficulty of connection and improving the reliability of connection of the two.

The connecting sleeve 12 is disposed in the pen tip 10, and the connecting sleeve 12 is at least partially wrapped on the outer wall of the spring needle, in other words, the connecting sleeve 12 is at least partially attached to the outer wall of the spring needle, so as to at least realize transverse positioning of the spring needle.

The stop 112 is embedded in the joint surface of the connecting sleeve 12 and the spring needle, so that the electrode is limited at the tip end of the inside of the pen point 10, and not only the axial positioning but also the transverse positioning of the spring needle are realized. Specifically, the connecting sleeve 12 is formed with a recess fitting the boss-shaped stopper 112, so that the connecting sleeve 12 is fitted to the boss-shaped stopper 112.

The spring needle electrode 11 establishes a jogged connection relationship with the connecting sleeve 12 through the stop part 112, so that the connecting sleeve 12 not only can be used for establishing a connection relationship with a structure in the pen holder 13 of the stylus 1, but also the connecting sleeve 12 can play a more accurate role in positioning and limiting the axial position of the spring electrode 111 relative to the connecting sleeve 12, so that the spring needle electrode 11 cannot deviate in the pen tip 10.

Further, the connecting sleeve 12 improves the accuracy of the signal transmitting position of the electrode 111 in the long-term use process by limiting the electrode 111 at the tip of the pen tip 10, thereby improving the positioning accuracy and consistency of the writing trace using the stylus 1. In addition, the electrode 111 is ensured to be close to the electronic device as much as possible in the use state, and the communication quality is improved. And the electrode 111 is connected as an organic whole with the spring needle, and after the electrode 111 carries out the accurate positioning, can ensure that the spring needle also by the accurate positioning, under the state of use, the spring needle can keep the cooperation state with the pressure sensor 15 directly or at intervals steadily for a long time, avoids spring needle poor positioning to lead to the spring needle atress unstable and then warp, namely improves the deformation resistance and the durability of this spring needle.

Compared with the scheme of directly adding the silica gel pad behind the pressure sensor 15, the spring needle of the stylus 1 has better durability, and the spring needle arranged in the pen tip 10 is far away from the high-temperature and high-humidity environment, so that the spring needle can continuously keep the elasticity and the initial size, and the stylus 1 can continuously buffer the pressure sensor 15.

The spring needle electrode 11 is accommodated in the pen tip 10, the electrode 111 of the spring needle electrode 11 is located at the tip of the pen tip 10, and the spring needle of the spring needle electrode 11 is used for being directly or indirectly connected with the pressure sensor 15 of the stylus 1, so that when the stylus 1 falls, the impact on the pressure sensor 15 caused by the spring of the spring needle electrode 11 can be buffered, and the electrode 111 of the spring needle electrode 11 is used for transmitting signals to electronic equipment and is usually used as the first transmitting electrode 111 of the stylus 1.

Optionally, when the stylus 1 falls, the tip of the pen tip 10 is easily touched, the electrode 111 is hemispherical, the hemispherical spherical surface faces the tip of the pen tip 10, the impact force can be decomposed by the hemispherical electrode 111, the impact force applied to the electrode 111 along the axial direction of the stylus 1 is reduced, the impact force required to be buffered by the spring needle electrode 11 is further reduced, the buffering effect of the spring needle electrode 11 is improved, and the durability of the spring needle electrode 11 is prolonged.

In an alternative of this embodiment, the spring needle includes a guide post 110, an elastic member 113, and a thimble 114, where the elastic member 113 may be, for example, a spring.

The guide post 110 is hollow, the guide post 110 has two opposite ends along its own length direction, one end of the guide post 110 is integrally formed with the electrode 111 to form a fixed end, and the stop portion 112 is disposed on the outer wall of the guide post 110, that is, the spring needle is integrally connected with the electrode 111 through the guide post 110, and is integrally connected with the stop portion 112.

The elastic element 113 is arranged in the guide pillar 110, one end of the thimble 114 is penetrated in the guide pillar 110, the elastic element 113 is propped between the thimble 114 and the electrode 111, the other end of the thimble 114 extends out of the guide pillar 110 to form an elastic end, and the elastic element 113 provides elastic force for the thimble 114, so that the thimble 114 can stretch and retract relative to the guide pillar 110, and the buffer function of the spring needle is realized.

The stopper 112 is engaged with the connecting sleeve 12 to position the guide post 110 in the axial and lateral directions with respect to the pen tip 10, thereby reliably positioning the spring needle electrode 11 as a whole with respect to the pen tip 10.

In an alternative embodiment of the present utility model, an inwardly turned lip 1100 is connected to the end of the guide post 110 facing away from the electrode 111, and one end of the thimble 114 protrudes out of the guide post via the lip 1100, i.e. the lip 1100 is turned inwardly relative to the guide post 110 and is wound around the end of the guide post 110 facing away from the electrode 111.

The thimble 114 is formed with an expanded diameter portion, which is spaced from one end of the thimble 114 extending out of the guide post 110 and can be abutted against the lip 1100 under the action of the elastic member 113. The diameter-expanding portion may be disposed in a middle portion of the length direction of the ejector pin 114 or an end portion of the diameter-expanding portion opposite to the lip 1100, so that the diameter-expanding portion may be stopped by the lip 1100, so that the diameter-expanding portion is limited in the guide pillar 110, and only one end of the ejector pin 114 may extend out of the guide pillar 110. The lip 1100 thus acts as a stop for the thimble 114, and prevents the thimble 114 from being pulled out of the guide post 110 on the premise that the thimble 114 can be used as an elastic contact.

Alternatively, the ejector pin 114 may be configured such that the cross-sectional area increases in a linear or nonlinear manner from the end away from the elastic member 113 to the end close to the elastic member 113, so that a portion between a position where the ejector pin 114 can abut against the lip 1100 and an end face where the ejector pin 114 contacts the elastic member 113 is formed as an enlarged diameter portion. Alternatively, a stepped enlarged diameter portion is provided at the middle portion of the ejector pin 114 or the end portion near the elastic member 113, and as shown in fig. 1, a stepped enlarged diameter portion is provided at the end portion of the ejector pin 114 near the elastic member 113.

In an alternative of this embodiment, the stop portion 112 includes an annular boss 1120 disposed around the guide post 110, specifically, a joint surface of the connection sleeve 12 and the guide post 110 is formed with a recess adapted to the annular boss 1120, and the annular boss 1120 is connected to the recess in a fitting manner, so that the annular boss 1120 and the connection sleeve 12 are connected in a fitting manner.

The annular boss 1120 establishes a fitting connection relationship with the connection sleeve 12 along the entire circumference of the pogo pin electrode 11, so that the annular boss 1120 can be more tightly and reliably connected with the connection sleeve 12.

In the alternative of this embodiment, the number of the annular bosses 1120 is plural, the plurality of annular bosses 1120 are arranged at intervals along the axial direction of the pen tip 10, and the plurality of annular bosses 1120 can be connected with the connection sleeve 12 in a jogged manner, so that the stylus 1 can form a plurality of jogged connections with the connection sleeve 12 through the stop portion 112, the stop effect of the stop portion 112 is improved, and the positioning reliability and the positioning accuracy of the spring needle electrode 11 in the pen tip 10 are further improved.

An annular separation groove 1121 is formed between the adjacent annular bosses 1120, the annular separation groove 1121 can be in jogged connection with the connecting sleeve 12, the stop part 112 with the annular separation groove 1121 and the annular bosses 1120 is in jogged connection with the connecting sleeve 12 in two different forms, the connection reliability of the stop part 112 and the connecting sleeve 12 can be further improved, and the positioning reliability and the positioning precision of the spring needle electrode 11 in the pen point 10 are further improved.

In an alternative of this embodiment, the electrode 111 is provided with a cavity 1110 communicating with the hollow portion of the guide post 110, and the elastic member 113 abuts against the electrode 111 in the cavity 1110.

According to the technical scheme, the concave cavity 1110 is formed in the electrode 111, and the concave cavity 1110 is configured to be communicated with the hollow part of the guide pillar 110, so that part of the elastic piece 113 is contained in the concave cavity 1110 and abuts against the electrode 111, and the other part of the elastic piece 113 is contained in the hollow part of the guide pillar 110 and abuts against the thimble 114.

It can be seen that the inner space of the electrode 111 can be fully utilized, and the requirement of the elastic member 113 for the axial length of the guide post 110 can be reduced, thereby being beneficial to realizing the miniaturization of the spring needle electrode 11.

In an alternative scheme of the embodiment, the stop portion 112 is integrally connected with the guide post 110, where the stop portion 112, the guide post 110 and the electrode 111 may be made of metal, and the three are integrally formed by an additional process, which is beneficial to improving the impact resistance of an integral structure formed by connecting the three.

In the alternative of this embodiment, the material of the connecting sleeve 12 is plastic, the connecting sleeve 12 and the spring needle electrode 11 are integrally injection-molded, the connecting sleeve 12 and the spring needle electrode 11 which are integrally injection-molded and connected can be more tightly matched, and the assembling process of the stylus 1 can be simplified and the assembling precision can be improved.

In an alternative scheme of the embodiment, the stylus 1 further comprises a pressure sensor 15, a mandrel assembly and the stylus 1, wherein the pressure sensor 15 is used for detecting the pressure born by the pen tip 10 during writing.

The pen holders 13 are disposed at intervals at the rear end of the pen tip 10, and it is understood that one end of the pen tip 10 having a tip is a front end, the other end of the pen tip 10 in the axial direction is a rear end, and the front end of the pen holder 13 and the rear end of the pen tip 10 form an interval, and the interval can be used for the pen tip 10 to be pressed relative to the pen holder 13 during the use of the stylus 1.

The front end of the spindle assembly is connected with the connection sleeve 12 and is formed with a front end face, in other words, the front end of the spindle assembly is connected with the connection sleeve 12 so that the spindle assembly is connected with the pen tip 10, and the spindle assembly can move synchronously with the pen tip 10 in the axial direction of the stylus 1. In addition, the front end face of the mandrel assembly is propped against the elastic end of the spring needle of the touch pen 1, so that the spring needle electrode 11 is propped against the mandrel assembly elastically, when the pen tip 10 falls, the pen tip 10 receives impact force, the spring needle electrode 11 buffers the impact force first and then transmits the impact force to the mandrel assembly, and therefore the spring needle electrode 11 can buffer the impact force received by the mandrel assembly effectively.

The rear end of the mandrel assembly is slidably arranged in the penholder 13 in a penetrating manner, so that the mandrel assembly can move in the penholder 13 along the axial direction of the penholder 13.

The pressure sensor 15 is connected with the pen holder 13 and the spindle assembly, so that in use, when the pen tip 10 is pressed, the spindle assembly moves backwards in the pen holder 13 along with the pen tip 10, the pressure sensor 15 is triggered and can detect the movement degree of the spindle assembly relative to the pen holder 13, and accordingly the pressure applied to the pen tip 10 is determined. In addition, since the spring needle electrode 11 can effectively buffer the impact force received by the mandrel assembly, the impact force received by the pressure sensor 15 can also be effectively buffered, and further the pressure sensor 15 is prevented from being damaged due to impact.

It is worth emphasizing that the mandrel component abuts against the spring needle electrode 11 in the stylus 1 in a point-to-face mode, so that high fault tolerance assembly of the mandrel component and the spring needle electrode can be achieved, and the joint of the mandrel component and the spring needle electrode can be guaranteed not to be disconnected in the falling process of the stylus 1 due to elastic abutting.

Optionally, the mandrel assembly includes a tubular shielding member 141 screwed with the connecting sleeve 12, and a conductive rod 142 penetrating through the tubular shielding member 141, where the front end of the conductive rod 142 extends into the connecting sleeve 12 and is formed with a front end surface, the front end surface of the conductive rod 142 abuts against the thimble 114 of the spring needle electrode 11, specifically, the front end surface of the conductive rod 142 may be provided with a pit for accommodating an end of the thimble 114, so that the thimble 114 and the front end surface of the conductive rod 142 are plugged through the pit, and positioning accuracy of the thimble and the conductive rod is improved.

The conductive rod 142 and the pogo pin electrode 11 are both configured as conductors, so that the electrode 111 can be electrically connected with the circuit board 16 in the pen holder 13 through the conductive rod 142, and the conductive rod 142 and the circuit board 16 can be electrically connected through the conductive elastic sheet 143.

Further, the mandrel assembly further comprises a cylindrical receiving electrode 144 sleeved outside the conducting rod 142, and the cylindrical receiving electrode 144 is used for receiving signals sent to the stylus 1 by the electronic equipment, so that the cylindrical receiving electrode 144 is matched with the first transmitting electrode 111 and the second transmitting electrode 145 to realize information interaction between the electronic equipment and the stylus 1.

An insulating layer may be provided between the cylindrical receiving electrode 144 and the conductive rod 142 to prevent signal interference therebetween, and the outer side of the cylindrical receiving electrode 144 is also covered with an insulating layer to prevent signal interference between the cylindrical receiving electrode 144 and the tubular shield 141. The tubular shield 141 may be configured to be grounded to improve the grounding reliability of the stylus 1.

The second emitter electrode 145 is cylindrical and is disposed between the inner wall of the barrel 13 and the tubular shield 141.

In an alternative of this embodiment, the pressure sensor 15 includes a force-sensitive deformation member 150 and a strain gauge, the force-sensitive deformation member 150 being connected between the spindle assembly and the inner wall of the barrel 13, the strain gauge being provided to the force-sensitive deformation member 150.

In this technical scheme, when the dabber subassembly moves for the inner wall of pen-holder 13, can pull power sensitive deformation member 150 and take place deformation, set up Yu Limin deformation member 150's strainometer and can detect power sensitive deformation member 150's deformation parameter to confirm the pressure that nib 10 received according to the testing result.

When the stylus 1 falls, the spring needle electrode 11 can sufficiently buffer the impact force, so that the excessive impact force can be prevented from being transmitted to the mandrel assembly through the spring needle electrode 11. Therefore, the mandrel component cannot deviate greatly when the stylus 1 falls, the force-sensitive deformation member 150 cannot be excessively deformed accidentally, and the force-sensitive deformation member 150 cannot be plastically deformed due to the falling of the stylus 1, so that the basic performance of detecting pressure through self deformation can be maintained.

Alternatively, the force-sensitive deformation member 150 extends in a direction consistent with the lateral direction of the barrel 13 when the nib 10 is in an unpressed state.
