Detailed Description

In order to make the technical solutions of the present application better understood by those skilled in the art, the present application is further described in detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of an electronic device according to the present disclosure.

As shown in fig. 1, an embodiment of the present application relates to an electronic device including an electronic pen 100 and a host 200.

Host 200 may specifically be a handheld component, a vehicle-mounted component, a wearable component, a computing component, or other processing component connected to a wireless modem. Cellular telephones (cellular phones), smart phones (smart phones), personal Digital Assistants (PDAs), tablet computers, portable computers, laptop computers (laptop computers), video cameras, video recorders, still cameras, smart watches (smart watches), smart bracelets (smart phones), vehicle-mounted computers, ink-jet screens, and other screen-enabled and touch-enabled terminal components may also be included.

In the embodiment of the present application, the specific form of the host 200 is not particularly limited, and for convenience of understanding, the host 200 is taken as an example for explanation. In a specific application, the ink screen can also interact with a computer or other equipment, for example, a document annotated or written on the ink screen can be synchronously displayed in the computer or other equipment, that is, the ink screen can also be used as an input part of the computer or other equipment.

The host 200 has a display screen (not shown), which may be a touch screen for performing touch operations. The electronic pen 100 is an input component of the host 200, and a user can write or draw on a display screen of the host 200 through the electronic pen 100.

As described in the background section, in the conventional solution, the position of the center of gravity of the electronic pen 100 is fixed, and in general, the position of the center of gravity of the electronic pen 100 is approximately located on the central area in the length direction of the electronic pen 100. However, the pen-holding postures of different persons are different, and the pen-holding postures are also different when different operations such as writing and drawing are performed. Under different pen holding postures, the design of fixing the gravity center position easily brings uncomfortable feeling, and under the condition of long-term use, fatigue is easily generated, so that the use experience of a user is poor.

In view of this, the present embodiment provides an electronic pen 100, which is configured with a driving portion, where the driving portion can drive an internal device inside the electronic pen 100 to displace, so as to change a position of a center of gravity of the electronic pen 100. Thus, based on different use requirements of the user, the electronic pen 100 can provide various gravity center position selections, and can better adapt to the use requirements of the user, so as to improve the use experience of the user, and further improve the competitiveness of the product.

Referring to fig. 2 to fig. 3, fig. 2 is a perspective view of an electronic pen according to an embodiment of the present disclosure, and fig. 3 is an exploded view of the electronic pen according to the embodiment of the present disclosure.

As shown in fig. 2 and 3, the electronic pen 100 includes a pen body 1 and several internal devices disposed inside the pen body 1.

The pen body 1 constitutes an external structure of the electronic pen 100, determines the overall shape of the electronic pen 100, and can protect internal devices. In the embodiment of fig. 3, the pen body 1 may include a split barrel 11, a pen tip 12 and a pen cap 13, wherein the barrel 11 is substantially cylindrical, which constitutes the main structure of the pen body 1 and provides a mounting chamber for internal components, the pen tip 12 is located at the front end of the barrel 11, and the pen cap 13 is located at the end of the barrel 11 for sealing the end. In this embodiment, the connection manner of the pen tip 12, the cap 13, and the barrel 11 may not be limited as long as the reliability of the connection can be ensured; if the disassembly requirement exists, the characteristic of disassembly is also considered, for example, threaded connection, clamping connection, proper interference assembly and the like can be adopted.

It should be understood that the structural form of the pen body 1 shown in fig. 3 is merely an exemplary illustration and cannot be used as a limitation to the implementation range of the electronic pen 100 provided in the embodiment of the present application, and in the specific implementation, a person skilled in the art may adjust the structural form of the pen body 1 in combination with the related art. For example, the pen tip 12 and the barrel 11 may be of an integral structure, or the cap 13 and the barrel 11 may be of an integral structure; the pen body 1 may further include a pen clip, which may be installed on the pen holder 11, or the pen clip may be installed between the pen holder 11 and the pen cap 13, which may facilitate the placement of the electronic pen 100; the pen body 1 may further include a pen cap, the pen cap is detachably assembled on the pen holder 11 for protecting the pen point 12, and the specific detachable assembling manner includes a threaded connection, a clamping connection and the like.

The internal device is a functional device of the electronic pen 100, and there may be many choices of the type thereof, and specifically, there is a relationship with the function of the electronic pen 100. Generally, the internal device may be an electronic device, such as a motherboard 5 and a battery 4, the motherboard 5 may be integrated with a controller, and the battery 4 is used for supplying power. According to the use requirement, the battery 4 can be arranged as a detachable and replaceable component so as to be convenient for a user to replace; alternatively, the internal device may be a structural device, such as a mounting rack for mounting electronic devices such as an antenna, a battery 4, a main board 5, and a sensor; alternatively, the internal device may also be a combined device of a structural device and an electronic device, such as an antenna module including a mounting bracket and an antenna, a sensor module (e.g., a pressure-sensitive module) including a mounting bracket and a corresponding sensor, and the like.

Further, the electronic pen 100 provided in the embodiment of the present application may further include a driving portion 2, where the driving portion 2 is connected to at least one internal device, where the connection includes direct connection and indirect connection, where direct connection means that the driving portion 2 is directly connected to the corresponding internal device, and indirect connection means that the driving portion 2 is connected to the corresponding internal device indirectly through other components as a transition piece. Of the internal devices, only some of the internal devices may be connected to the driving section 2, or all of the internal devices may be connected to the driving section 2. For convenience of description, the internal devices connected to the driving part 2 may be referred to as one type of device, and the remaining internal devices may be referred to as two types of devices.

The driving part 2 is configured to drive the above-mentioned devices to displace along the axial direction of the pen holder 11, and during the displacement of the devices, the position of the center of gravity of the electronic pen 100 may change, which may better adapt to different requirements of users. The gravity center adjustment method depends on the electronic pen 100 itself, i.e. the internal components, to perform the displacement, and no other gravity accessories are introduced, so that the number of the components of the electronic pen 100 can be relatively small, and the weight and the structural complexity of the electronic pen 100 are not excessively increased.

In some embodiments, the number of devices of a type may be one. At this time, the driving part 2 is preferably directly connected to a type of device to simplify the structure.

In other embodiments, the number of the devices of one type may also be multiple, in this case, the transition frame 3 may also be disposed in the pen holder 11, and multiple devices of one type may be mounted on the transition frame 3. The transition frame 3 corresponds to a transition piece, and the driving part 2 can be directly connected with the transition frame 3 to form an indirect connection relationship with a device of a kind. The transition frame 3 and the pen holder 11 can be connected in a sliding manner, and the driving part 2 is configured to drive the transition frame 3 to displace along the axial direction of the pen holder 11, so that each type of device can be driven to displace synchronously. With this arrangement, the connection structure of the driving section 2 and the various devices can be relatively simple, which is advantageous for simplifying the internal structure of the electronic pen 100.

Here, the embodiment of the present application does not limit the sliding connection structure between the transition frame 3 and the pen holder 11, and in the specific implementation, a person skilled in the art may set the sliding connection structure according to actual needs as long as the sliding connection structure can meet the use requirements. For example, the inner wall of the pen holder 11 may be provided with a sliding groove, the transition frame 3 may be provided with a sliding block, and the sliding guide of the transition frame 3 may be realized through the cooperation of the sliding block and the sliding groove.

In addition, the embodiment of the present application does not limit the types of devices, and in the specific implementation, a person skilled in the art may configure the devices according to actual needs as long as the technical purpose of adjusting the center of gravity is satisfied. In an exemplary scheme, one type of device may include the battery 4 and the main board 5, and the volume and the weight of the battery 4 and the main board 5 in each internal device are relatively large, and when the position of the battery 4 and the position of the main board 5 are adjusted, the change of the position of the center of gravity of the electronic pen 100 is particularly obvious, which is beneficial to increasing the range of the center of gravity adjustment.

The driving part 2 may be a manual shifting block (not shown in the figure), a part of the manual shifting block may extend into the pen holder 11 for connecting with a type of device, and a part of the manual shifting block may be exposed to the outside of the pen holder 11, and during a specific operation, a user may apply an acting force to the part of the manual shifting block exposed to the outside of the pen holder 11 to drive the type of device to displace through the manual shifting block. In this embodiment, the driving unit 2 is relatively simple in configuration, but the driving unit 2 itself cannot generate the driving force, and the user needs to apply the driving force to the manual pad with a finger or the like.

Alternatively, the driving part 2 may be an electric driving part, and the electric driving part may be disposed in the barrel 11. In this kind of embodiment, drive division 2 can produce drive power by oneself, need not the manual work and applies and dial power, and the operation is simpler, convenient, laborsaving, can improve user's use and experience to can promote the degree of automation and the science and technology of equipment and feel. More importantly, the driving part 2 can be wholly packaged in the pen holder 11, the rod wall of the pen holder does not need to be penetrated, and the outer wall surface of the pen holder 11 is relatively complete, so that the appearance of a product can be guaranteed, the comfort of a user in holding can be improved, and the use experience of the user can be further improved.

The electric driving element can be a linear motor, and the linear motor can directly output linear displacement required by a class of devices, so that the class of devices are controlled to displace in the penholder 11. Or, the electric driving element may further include a rotating electrical machine, and the displacement form directly output by the rotating electrical machine is a rotational displacement, which does not satisfy the displacement requirements of the devices of the same type, and at this time, the electric driving element may further be matched with a transmission mechanism in the form of a rack-and-pinion mechanism, a screw mechanism, or the like, so as to convert the rotational displacement directly output by the rotating electrical machine into a required linear displacement; in some embodiments, the electric drive formed by the rotating motor in combination with the lead screw mechanism is also referred to as a linear stepper motor.

In some alternative embodiments, the outer wall of the pen shaft 11 may be provided with a signal input portion 111, and the signal input portion 111 may be in signal connection with the electric driving member for controlling the start and stop of the electric driving member. In a specific operation, a user may input a control signal through the signal input part 111 to actively control the electric driver, thereby actively adjusting the position of the center of gravity of the electronic pen 100.

The signal input portion 111 may be a pressing operation portion, and by pressing different positions, the electric driving member may be controlled to drive one type of component to displace in different directions (towards the pen tip 12 or the pen cap 13).

The signal input 111 may be a dedicated component, i.e. the signal input 111 may be used only for controlling the start and stop of the electric drive. Alternatively, the signal input unit 111 may be integrated with other functions, for example, the signal input unit 111 may be integrated with an input control function of the electronic pen 100, and is configured to switch the input of the electronic pen 100 to an eraser, a writing pen, and the like, so as to realize the input of different signals on the host 200, in this case, the signal input unit 111 has a stronger function, and the number of signal input elements disposed on the outer wall of the pen barrel 11 may be reduced, so as to simplify the structure of the pen body 1; with the increase of the integrated functions of the signal input part 111, the control modes corresponding to the signal input part 111 may be more diversified, for example, the control modes of the signal input part 111 may include pressing different positions, long pressing, short pressing, and the like, and different functions may be realized by different control modes.

Referring to fig. 4, fig. 4 is a schematic diagram illustrating selection of a center position of an electronic pen by shaking.

As shown in fig. 4, the electronic pen 100 may actively adjust the position of the center of gravity by transmitting a control signal to the electric driver in a swing manner, in addition to the signal input unit 111. At this time, a sensor for detecting the flick direction and the flick speed may be configured inside the electronic pen 100, and the controller may store a speed threshold, and when the flick speed is greater than the speed threshold, the controller may transmit a control signal to the electric driving element according to the flick direction to adjust the position of the center of gravity of the electronic pen 100.

In this embodiment, the electric drive controls the positional displacement of one type of device in a stepwise manner, i.e. each flick action determines the amount of adjustment of the position of the center of gravity, so that adjustments of different positions of the center of gravity can be made by multiple flicks. Of course, the adjustment amount of the center of gravity position may be determined by the swing speed, and in this case, the larger the swing speed, the larger the adjustment amount of the center of gravity position.

In some alternative embodiments, the electronic pen 100 may further include a touch sensing part 6 and a controller. The Touch sensing part 6 may be Touch film (i.e., touch film), and the Touch sensing part 6 may be disposed on an inner wall surface of the pen holder 11, and is used for accurately sensing and detecting an application state of the electronic pen 100, where the application state includes a working state and an idle state, and the working state and the idle state are distinguished whether the electronic pen 100 is held by a user; the controller may be integrated with the motherboard 5, and the controller, the touch sensing part 6, and the electric driving device may be connected by signals.

According to the application state of the electronic pen 100 detected by the touch sensing part 6, the controller may send a corresponding control instruction to the electric driving part, and the electric driving part may respond to the control instruction to drive one type of device to move to a corresponding position, thereby implementing intelligent adjustment of the gravity center position of the electronic pen 100.

In particular, a class of devices may have an operating position and an idle position; when the application state of the electronic pen 100 is the working state, the electric driving element can move one type of device to the working position; when the application state of the electronic pen 100 is the idle state, the electric driver may move one type of device to the idle position. The rest position is closer to the tail end of the electronic pen 100 than the working position, that is, the center of gravity of the electronic pen 100 is closer to the tail end of the electronic pen 100 in the rest position. With such an arrangement, when the application state of the electronic pen 100 is the idle state, the gravity center of the electronic pen 100 may be located at a position relatively close to the tail end of the electronic pen 100, so that when the electronic pen 100 falls, the probability that the pen tip 12 faces downward is relatively low, and the possibility that the pen tip 12 is damaged is relatively low.

When the working state of the electronic pen 100 is the drawing sub-state, the controller may send a control command to the electric driving part, and the electric driving part may move one type of device to the drawing sub-position. When the operation state of the electronic pen 100 is the writing sub-state, the controller may send a control command to the electric driving part, and the electric driving part may move one type of device to the writing sub-position.

As shown in fig. 5, when the touch sensing part 6 detects that the electronic pen 100 is in the working state, the host 200 may display a pop-up window, where the pop-up window has options of "drawing sub-state" and "writing sub-state", and when the user selects different options, the signal generating part may send different control instructions to the controller, and then the controller may drive one type of device to shift through the electric driver, so as to switch the state of the electronic pen 100, and further adjust the position of the center of gravity of the electronic pen 100.

In fact, the center of gravity adjustment command of the electronic pen 100 may also be entirely issued by the host 200. As shown in fig. 6, the host 200 may be provided with a signal generating part, the display screen of the host 200 may have an adjusting window, the adjusting window may have an adjusting button, and a user may input an adjusting instruction through the adjusting button, and then, the signal generating part may send a control instruction to the controller of the electronic pen 100, and the electric driver may drive a type of device in the electronic pen 100 to displace so as to adjust the position of the center of gravity of the electronic pen 100. The adjustment window of the host 200 may display the position of the center of gravity of the electronic pen 100 in the form of a progress bar.

The host 200 may also provide a specific indication of the position of the center of gravity, and at this time, the electronic pen 100 may further include a center of gravity detecting component 7, where the center of gravity detecting component 7 may be specifically a center of gravity sensor or the like, and may directly detect real-time center of gravity position information of the electronic pen 100, and the controller may obtain the real-time center of gravity position information and send the information to the host 200 to be displayed on the host 200.

Besides, the embodiment of the application also provides a scheme for indirectly acquiring the real-time gravity center position information. In this scheme, the electronic pen 100 may further be configured with a position sensor, and the position sensor is disposed in the pen holder 11 and is used for acquiring position information of a type of device; the controller stores initial gravity center position information of the electronic pen 100 in an initial state, which may be an equipment factory state; there is a first mapping relationship between the displacement of the first type device and the amount of change in the center of gravity position of the electronic pen 100, and the controller stores the first mapping relationship. Thus, by acquiring the position information of the first type of device, the displacement (compared with the initial state) of the first type of device in the pen holder 11 can be acquired, the gravity center position variation can be calculated through the displacement and the first mapping relation, and then the real-time gravity center position information of the electronic pen 100 can be acquired by combining the initial gravity center position information.

In one embodiment, the position sensor may be a distance measuring sensor, such as an ultrasonic sensor, an infrared sensor, an electromagnetic wave sensor, or the like, and the distance measuring sensor is used to detect distance information between the distance measuring sensor and a type of device. It can be known that, in the initial state, there is a first distance between the distance measuring sensor and the first kind of device, after the position adjustment, there is a second distance between the distance measuring sensor and the first kind of device, and the difference between the second distance and the first distance is the displacement of the first kind of device compared with the initial state.

In another scheme, the position sensor may also be a driving detection sensor, and the driving detection sensor is used for detecting the position information of the electric driving part so as to indirectly acquire the position information of one type of device. It can be appreciated that a second mapping exists between the position information of the electric actuator and the position information of a type of device.

The kind of this drive detection sensor is relevant with the kind of electric drive piece, if electric drive piece is the rotating electrical machines, drive detection sensor can be encoder etc. for detect the angular displacement of rotating electrical machines, and then can acquire angular position information. If the electric driving part is a linear motor, the driving detection sensor can also be a distance measurement sensor for detecting the linear displacement of the rotor of the linear motor, and further the linear position information can be acquired.

The foregoing is only a preferred embodiment of the present application and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present application, and these improvements and modifications should also be considered as the protection scope of the present application.
