Specifically, as shown in fig. 1, the stylus pen 11 in the embodiment of the present application includes a barrel 110 and a metal cap 111. The metal cap 111 is fixed to one end of the barrel 110, and the other end of the barrel 110 is a nib portion. The pen holder 110 is made of a memory alloy, for example, the memory alloy is machined into a hollow tubular structure, or the wall of the hollow tube is hollowed out to form a hollow tubular structure with meshes. A thermal resistor electrically connected with the memory alloy can be arranged inside the pen holder 110. The metal cap 111 is made of common iron or alloy, and the metal cap 111 is fixedly connected with the pen holder 110 and can be electrically connected through the contact of the metal cap and the pen holder. For example, the barrel 110 and the metal cap 111 are screwed and fixed together.

The groove 112 capable of contacting with a power supply is formed in the metal pen cap 111, when a user brings the groove 112 of the handwriting pen 11 close to an electrode of the power supply, after the groove 112 is conducted with the power supply, the pen holder 110 generates heat after being electrified, and along with the rise of temperature, based on the characteristic of high-temperature recovery of the memory alloy, the pen holder 110 can be deformed and reduced to an original first shape, when the pen holder 110 is in the first shape, the radial dimension of the pen holder 110 is thin, and the pen holder 110 which is thinned at the moment can be easily and smoothly stored in a narrow space to avoid space occupation. When a user desires to write with stylus 11, recess 112 is disconnected from the power source once stylus 11 is engaged. When the pen holder 110 is powered off, the heat productivity of the pen holder 110 is reduced, the temperature is lowered, the pen holder 110 can be deformed and expanded to the second shape, and when the pen holder 110 is in the second shape, the radial size of the pen holder 110 is thick, so that a user can hold writing more easily, and the writing comfort is better.

Optionally, an elastic protection layer is disposed on an outer wall of the pen holder 110, and the elastic protection layer is disposed outside the groove 112.

Specifically, in order to further improve the holding comfort of the stylus pen 10, an elastic protection layer with a large frictional resistance, for example, a soft rubber protective sleeve or a coating with an anti-slip frosted texture, may be further disposed on the outer wall of the pen holder 110. It should be noted that, in order to avoid the elastic protection layer from obstructing the electrical connection between the stylus pen 10 and the power supply, the elastic protection layer needs to avoid the groove 112 of the metal pen cap 11.

Optionally, the stylus pen 11 further includes a first magnetic member, and the first magnetic member is magnetically connected to the second magnetic member to fix the stylus pen.

Specifically, in order to reliably store the stylus pen 11, the first magnetic member may be fixed on the stylus pen 11, the second magnetic member may be disposed in the storage device, when the user brings the stylus pen 11 close to the storage device, the two magnetic members are opposite in opposite magnetic poles by adjusting the direction, and the stylus pen 11 is reliably installed in the storage device and cannot fall off under the magnetic attraction effect, so that the risk of loss is avoided.

Specifically, as shown in fig. 3, the groove 112 on the metal pen cap 111 may include a first groove 1121 and a second groove 1122, and the two grooves may be respectively connected to different power supplies to achieve conduction of the circuit. Since the metal cap 111 is connected to the pen holder 110 made of memory alloy, when the first groove 1121 is connected to the positive electrode of the power supply and the second groove 1122 is connected to the negative electrode of the power supply, the pen holder 110 can be connected to the circuit at this time, so as to control the temperature and change the thickness of the pen holder. The design scheme of two recesses still helps guaranteeing the reliable electrical contact when handwriting pen and the equipment main part installation to play the constraint effect in handwriting pen's axial, prevent the landing.

Optionally, the barrel 110 is any one of a titanium-nickel-based memory alloy barrel, a copper-based memory alloy barrel or an iron-based alloy barrel.

Specifically, in practical application, the pen holder 110 can be manufactured from any one of a titanium-nickel-based memory alloy, a copper-based memory alloy and an iron-based alloy according to specific mechanical and conductive heating properties, so as to meet the fatigue life requirement of a corresponding use scene.

Optionally, referring to fig. 1, the stylus pen 11 further includes a function switch 113 disposed on the pen holder 110, where the function switch 113 is configured to control an accessory device to be turned on or off, and the accessory device at least includes a laser pointer.

Specifically, the stylus pen 11 of the present embodiment may be integrated with other accessory devices, such as a laser pointer for pointing, in addition to providing a conventional handwriting input function. Meanwhile, as shown in fig. 3, a function switch 113 may be provided on the cartridge 110 to control the opening and closing of the accessory. For example, when the user desires to use the stylus pen 11 as a laser pen, the depressible function switch 113 illuminates the laser pointer to emit red or green light. It can be understood that when the stylus pen 11 is integrated with an accessory, an independent battery may be built in the stylus pen for supplying power, which is not described in this embodiment.

Referring to fig. 2, an electronic device 10 is further provided in an embodiment of the present application, where the electronic device 10 is provided with a pen slot 101 for accommodating a stylus pen 11, a side wall of the pen slot 101 is provided with an elastic contact 102, and the elastic contact 102 is electrically connected to a main board circuit of the electronic device 10; wherein the elastic contact 102 is used for supplying power to the stylus pen.

Specifically, as shown in fig. 2, the present embodiment provides an electronic device 10, which is a device with a handwriting input function, such as a mobile phone, a tablet computer, a notebook computer, etc., with a touch input screen installed. The stylus pen 11 may be an input tool used in conjunction with the electronic device 10, and when the user uses the electronic device 10, the user may use the stylus pen 11 to write characters and draw pictures on the display screen of the electronic device 10, or may click a virtual key on the screen to complete a touch operation.

As shown in fig. 2, a pen slot 101 is formed in the electronic device 10, and the pen slot 101 may be disposed along a length direction or a width direction of the electronic device 10, specifically, may be disposed on a front surface where the display screen is located, or disposed on a back surface where the battery cover is located, or disposed on a sidewall position along a thickness direction of the electronic device 10. The specific position of the pen slot 101 may be set according to the actual structural space of the electronic device 10, which is not limited in this embodiment of the application. When the stylus pen 11 is not needed, the stylus pen 11 can be put into the pen slot 101 so as to be convenient to store and carry.

The side wall of the pen slot 101 is provided with an elastic contact 102, and the elastic contact 102 is electrically connected to a main board circuit of the electronic device 10, and it is easily understood that the elastic contact 102 is connected to a battery in the electronic device 10. The spring contact 102 may be considered as an exposed contact that may provide power to the stylus 11. It should be noted that the elastic contact 102 has a telescopic deformation capability, when a user puts the stylus pen 11 into the pen slot 101, the groove 112 is firstly contacted with the elastic contact 102, after the contact, the pen holder 110 generates heat after being electrified, and along with the rise of temperature, based on the characteristic of high-temperature recovery of the memory alloy, the pen holder 110 can be deformed and reduced to the original first shape, when the pen holder 110 is in the first shape, the radial dimension of the pen holder 110 is thinner, and the pen holder 110 which is thinned at this time can be easily and smoothly inserted into the pen slot 101 for storage. When a user needs to use the writing pen 11 for writing, once the writing pen 11 is taken out of the pen slot 101, the elastic contact 102 is disconnected from the groove 112, the power of the pen holder 110 is cut off, the heat productivity of the pen holder 110 is reduced, the temperature is reduced, the pen holder 110 can be deformed and expanded to a second shape, when the pen holder 110 is in the second shape, the radial dimension of the pen holder 110 is thick, at the moment, the user can hold the writing more easily, and the writing comfort is better.

Therefore, in the embodiment of the application, the pen slot of the electronic device can play a role in storage, and on the other hand, the thickness change of the stylus pen can be automatically controlled according to two different states of assembling or separating the stylus pen with the pen slot.

Optionally, referring to fig. 2, the elastic contact 102 includes a first contact 1021 and a second contact 1022 that are oppositely disposed, where the first contact 1021 is electrically connected to a positive electrode of the motherboard circuit, and the second contact 1022 is electrically connected to a negative electrode of the motherboard circuit.

Specifically, as shown in fig. 2, the elastic contact 102 may be disposed on two opposite sidewalls of the pen slot 101 of the electronic device 10, for example, one sidewall may fix the first contact 1021, and the other sidewall may fix the second contact 1022. The first contact 1021 and the second contact 1022 are oppositely disposed, the first contact 1021 is electrically connected to a positive terminal of a motherboard circuit on the electronic device 10, and the second contact 1022 is electrically connected to a negative terminal of the motherboard circuit. It is easily understood that, based on the conduction of the internal circuit of the motherboard circuit, the first contact 1021 may be regarded as the positive pole of the battery, and the second contact 1022 may be regarded as the negative pole of the battery, so that when the conductor is connected between the first contact 1021 and the second contact 1022, the conductor can be electrified to generate heat. That is, once the metal cap 111 of the stylus pen 10 connects the first contact 1021 and the second contact 1022, the pen shaft 110 is powered on to generate heat, and a battery does not need to be disposed inside the stylus pen, so that the internal space of the stylus pen can be saved.

Optionally, referring to fig. 2 and 3, the elastic contact 102 is a hemispherical metal shell protruding from an inner wall of the pen slot 101.

Specifically, as shown in fig. 3, a hemispherical metal shell made of a copper sheet or a galvanized iron sheet with elastic properties may be used as the elastic contact 102, the elastic contact 102 may be soldered to a main board circuit, and openings may be formed on both sides of the inner wall of the pen container 101, as shown in fig. 2, when the main board is installed in the electronic device 10, the elastic contact 102 may be exposed from the opening on the inner wall of the pen container 101 and protrude from the inner wall of the pen container 101. Thereby ensuring that the resilient contact 102 is in operative contact with the recess 112.

Optionally, referring to fig. 3, the electronic device 10 further includes a metal dome switch 103, where the metal dome switch 103 is disposed in the inner cavity of the hemispherical metal shell, and the metal dome switch 103 is electrically connected to the motherboard circuit.

It should be noted that, unlike the physical contact or disconnection between the elastic contact 102 and the groove 112 to achieve the power on or off of the pen holder 110, with the dome switch 103, the groove 112 may press the elastic contact 102 and simultaneously trigger the dome switch 103 to perform finer control, or the elastic contact 102 and the dome switch 103 may be used to achieve dual-path protection to avoid interfering with the operation of the motherboard circuit.

Optionally, referring to fig. 2, a soft pad 13 is disposed in the pen slot 101 at a position where it is engaged with the nib of the stylus pen 11.

Specifically, as shown in fig. 2, in order to avoid abrasion of the pen tip caused by frequent taking and placing of the stylus pen 11, a soft pad 13 may be disposed at a position where the pen slot 101 is matched with the pen tip of the stylus pen 11, and the soft pad 13 may be a silicone pad, a sponge pad, or the like, so as to reduce abrasion of the pen tip and avoid the worn pen tip from scratching the display screen.

Optionally, the electronic device 10 further includes a second magnetic member, and the second magnetic member is disposed in the pen slot 101;

when the stylus pen 11 is close to the pen slot 101, the second magnetic member and the first magnetic member disposed on the stylus pen 11 attract each other.

Specifically, in order to reliably store the stylus pen 11, the second magnetic member may be fixed in the pen slot 101 of the electronic device 10, when the user holds the stylus pen 11 close to the pen slot 101, the direction is adjusted to make the opposite magnetic poles of the two magnetic members opposite, and under the magnetic attraction effect, the stylus pen 11 is reliably installed in the electronic device 10 without falling, so that the risk of loss is avoided.

Referring to fig. 1 to 4, schematic structural diagrams of an input device set according to an embodiment of the present application are shown, where the input device set includes an electronic device 10 and a stylus 11;

the device body 10 is provided with a pen slot 101 for accommodating the stylus pen 11, the side wall of the pen slot 101 is provided with an elastic contact 102, and the elastic contact 102 is electrically connected with a main board circuit of the device body 10;

the handwriting pen 11 comprises a pen holder 110 and a metal pen cap 111, wherein the pen holder 110 is a memory alloy pen holder, the metal pen cap 111 is fixed at the end of the pen holder 110, and the metal pen cap 111 is provided with a groove 112 matched with the elastic contact 102;

under the condition that the groove 112 is in contact with the elastic contact 102, the pen holder 110 is connected into the main board circuit, and the pen holder 110 generates heat and deforms to a first shape; under the condition that the groove 112 is disconnected from the elastic contact 102, the pen holder 110 is disconnected from the main board circuit, and the pen holder 110 is cooled and deformed to a second shape; wherein a thickness degree of the first shape is smaller than a thickness degree of the second shape.

Specifically, for specific structures of the electronic device 10 and the stylus 11, reference may be made to the description of the foregoing embodiments and the schematic diagrams of fig. 1 to 3, which are not described herein again. With reference to the electronic device 10 and the stylus pen 11 provided in the foregoing embodiments, as shown in fig. 4, when the stylus pen 11 is to be placed into the pen slot 101, the groove 112 contacts the elastic contact 102 first, and after the contact is conducted, the pen barrel 110 is powered on and then generates heat, and as the temperature rises, based on the high-temperature recovery characteristic of the memory alloy, the pen barrel 110 may be deformed and reduced to the original first shape, and when the pen barrel 110 is in the first shape, the radial dimension of the pen barrel 110 is relatively small, and the pen barrel 110 that is thinned can be easily and smoothly inserted into the pen slot 101 for storage. When a user needs to use the writing pen 11 for writing, once the writing pen 11 is taken out of the pen slot 101, the elastic contact 102 is disconnected from the groove 112, the power of the pen holder 110 is cut off, the heat productivity of the pen holder 110 is reduced, the temperature is reduced, the pen holder 110 can be deformed and expanded to a second shape, when the pen holder 110 is in the second shape, the radial dimension of the pen holder 110 is thick, at the moment, the user can hold the writing more easily, and the writing comfort is better.

In the embodiment of the application, when a user uses the handwriting pen as an input component, when the handwriting pen is taken out of the pen slot of the device body, the memory alloy pen holder is disconnected from the main board circuit, the memory alloy pen holder is powered off, at the moment, the heat productivity of the pen holder is reduced, the temperature is reduced, and the pen holder is deformed into a thicker second shape. When a user needs to store the handwriting pen into the pen groove, the groove at the metal pen cap can be contacted with the elastic contact in the pen groove, so that the pen holder is electrified and heated, and the pen holder is restored to a first thin shape after being heated along with the rise of temperature based on the memory characteristic of the memory alloy, and the handwriting pen can be easily and smoothly stored in the pen groove. Therefore, the electronic equipment that this application embodiment provided, the pen-holder of handwriting pen can become thick when user state, and the user grips more firmly comfortable when using, and the pen-holder of handwriting pen can become thin when accomodating, is convenient for assemble with electronic equipment, can effectively compromise accomodating convenience and the operation travelling comfort of handwriting pen.

Alternatively, referring to fig. 4, in a case where the stylus pen 11 is completely inserted into the pen slot 101, the groove 112 is spaced from the elastic contact 102 by a predetermined distance.

Specifically, as shown in fig. 4, after the handwriting pen 11 is completely inserted into the pen slot 101 and installed in place, if the groove 112 is still in continuous contact with the elastic contact 102, the pen barrel 110 will continuously maintain the power-on state, will continuously contract within the contraction limit range of the memory alloy, and will be in the continuous power consumption state, which will shorten the endurance of the device body 10, so that, after the handwriting pen 11 is completely inserted into the pen slot 101, the groove 112 and the elastic contact 102 are spaced by a preset distance, that is, at this time, the groove 112 and the elastic contact 102 are disconnected and not in contact, so that the pen barrel 110 is powered off, and although the pen barrel 110 is cooled and thickened after power is off, the thickened pen barrel 110 is beneficial to the tightness of assembly. In addition, on one hand, the pen shaft 110 is not infinitely thickened due to the constraint of the pen slot 101, and on the other hand, the thickened range can be within the allowable range through accurate calculation. The preset distance between the groove 112 and the elastic contact 102 can be realized by controlling the fitting size between the groove 112 and the elastic contact 102, for example, before the stylus pen 11 is placed into the pen slot 101, the two are in an interference fit state, that is, the groove 112 and the elastic contact 102 can interfere with each other, and the elastic contact 102 is pressed to realize the close contact and conduction between the two. After the stylus pen 11 is placed in the pen slot 101 and the elastic contact 102 is reset, the stylus pen and the elastic contact 102 are in a clearance fit state, that is, the groove 112 and the elastic contact 102 are separated. Therefore, in the embodiment of the present application, the specific arrangement form of the preset distance between the groove 112 and the elastic contact 102 is not limited.
