Description

Technical Field

[0001] This application relates to the technical field of electronic products, and particularly to a pen and an electronic device. Background Art

[0002] In the prior art, some electronic devices are usually equipped with a stylus. To facilitate the user to pick up and place the stylus, the stylus is usually attracted and combined with one side of the electronic device. At the same time, to further improve the attraction effect between the stylus and the electronic device, the attraction surface of the stylus is usually set as a flat surface, so as to increase the contact area between the stylus and the electronic device. The stylus generally includes a pen body and a pen cap, and the pen cap and the pen body are usually connected by a threaded connection method, which easily causes a certain assembly error between the pen body and the pen cap. When there is an assembly error between the pen cap and the pen body, the attraction surface of the pen cap and the attraction surface of the pen body may be relatively displaced in position, resulting in a decrease in the flatness of the overall attraction surface of the stylus, and further affecting the attraction effect between the stylus and the electronic device. It can be seen that the existing stylus has a problem of poor assembly effect. Summary of the Invention

[0003] This application provides a pen and an electronic device, which can solve the problem of poor assembly effect existing in the existing stylus.

[0004] To solve the above technical problems, this application is implemented as follows:

[0005] In a first aspect, an embodiment of this application provides a pen, which is characterized by including:

[0006] A pen body, one end of the pen body facing away from the pen tip forms an open end, and a card slot is provided on the inner side wall of the pen body, and the card slot is close to the open end;

[0007] A pen cap, the pen cap is inserted into the pen body along the open end;

[0008] A first elastic member, the first elastic member is arranged in the pen cap;

[0009] Wherein, when the pen cap is inserted into the pen body, the first elastic member is clamped with the card slot, and the pen cap is connected to the pen body through the first elastic member.

[0010] In a second aspect, an embodiment of this application provides an electronic device, and the electronic device is the pen described in the first aspect above.

[0011] In the embodiments of the present application, the pen cap is inserted into the pen body, and when the pen cap is inserted into the pen body, the pen cap and the pen body are fixed by a first elastic member. Thus, during the assembly process, since it is not necessary to relatively rotate the pen cap and the pen body, the problem that the positions of the suction surfaces of the pen cap and the pen body are relatively displaced can be avoided, which is beneficial to improving the flatness of the suction surface of the stylus pen, and further improving the assembly effect of the stylus pen.

[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0022] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of this application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0023] The pen and the electronic device provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0024] Please refer to Figures 1-9 , which is a pen provided by an embodiment of the present application. The pen includes:

[0025] A pen body 100, one end of the pen body 100 facing away from the pen tip forms an open end, and a card slot 110 is provided on the inner side wall of the pen body 100, and the card slot 110 is close to the open end;

[0026] A pen cap 200, the pen cap 200 is inserted into the pen body 100 along the open end;

[0027] A first elastic member 230, the first elastic member 230 is disposed in the pen cap 200;

[0028] Wherein, when the pen cap 200 is inserted into the pen body 100, the first elastic member 230 is clamped with the card slot 110, and the pen cap 200 is connected to the pen body 100 through the first elastic member 230.

[0029] The above pen can be a stylus or a capacitive pen, and the stylus or the capacitive pen can be applied to various electronic devices with touch functions. For example, it can be a tablet computer, a mobile phone, etc. Hereinafter, taking the pen as a stylus as an example, the structure of the pen provided by the embodiments of the present application will be further explained.

[0030] The pen body 100 can be a hollow rod for the user to easily hold the stylus. The pen body 100 can include a pen tip to form the nib of the stylus, and the stylus operates on the touch screen of the electronic device based on the nib. The pen body 100 and the pen tip can be integrally formed or two separate components. When the pen body 100 and the pen tip are two separate components, they are fixedly connected. The pen cap 200 is connected to one end of the pen body 100 facing away from the nib to close the open end of the pen body 100. At the same time, a receiving cavity is formed between the pen body 100 and the pen cap 200 to receive the circuit module in the pen.

[0031] The above-mentioned first elastic member 230 can be fixedly connected to the pen cap 200. A part of the first elastic member 230 is located in the pen cap 200 to realize the fixed connection between the first elastic member 230 and the pen cap 200. At the same time, the first elastic member 230 can also include a part located on the outer side wall of the pen cap 200. In this way, when the pen cap 200 is inserted into the pen body 100, the part of the first elastic member 230 located on the outer side wall of the pen cap 200 can be embedded into the card slot 110, so that the pen cap 200 is snap-connected to the pen body 100 through the first elastic member 230.

[0032] It can be understood that the stylus in the embodiments of the present application can be a cylindrical stylus, a columnar stylus with a polygonal cross-section, or a stylus with a suction plane, etc. Hereinafter, taking the stylus with a suction plane as an example, the structure of the stylus in the embodiments of the present application will be further explained. For example, in an embodiment of the present application, a first plane 120 is arranged on the outer side wall of the pen body 100 along the length direction of the pen body 100, and a second plane 240 is arranged on the outer side wall of the pen cap 200 along the length direction of the pen cap 200. When the pen cap 200 is inserted into the pen body 100, the first plane 120 and the second plane 240 are in the same plane, and the first plane 120 and the second plane 240 together form the suction plane of the stylus. That is, when the stylus is suctioned to the electronic device, the first plane 120 and the second plane 240 are respectively attached to the electronic device.

[0033] Specifically, when assembling the stylus pen, it is only necessary to insert the pen cap 200 into the open end of the pen body 100. Since the first elastic member 230 can be embedded in the card slot 110 of the pen body 100 during the process of inserting the pen cap 200 into the pen body 100, in this way, the position fixation between the pen cap 200 and the pen body 100 can be achieved; at the same time, when the first elastic member 230 is embedded in the card slot 110, the relative position between the pen cap 200 and the pen body 100 can be further adjusted to ensure that the positions of the first plane 120 and the second plane 240 are aligned with each other.

[0034] It should be noted that when a protective layer is sprayed on the surface of the stylus pen, for example, when there is paint spraying on the surface of the stylus pen, if there is an assembly error between the pen body 100 and the pen cap 200, resulting in a certain angle between the first plane 120 and the second plane 240, one of the edges of the pen cap 200 usually protrudes from the plane where the first plane 120 is located. Thus, during the process of the stylus pen being attracted to the electronic device, it is easy for one of the edges of the pen cap 200 to directly collide with the electronic device. Since the stress area at the edge is small, after multiple collisions, the protective layer at the collided edge is likely to fall off. In the embodiment of the present application, by aligning the first plane 120 and the second plane 240, the problem of the protective layer on the surface of the stylus pen falling off can be alleviated.

[0035] In this embodiment, by inserting the pen cap 200 into the pen body 100 and, when the pen cap 200 is inserted into the pen body 100, fixing the pen cap 200 and the pen body 100 through the first elastic member 230. In this way, during the assembly process, since it is not necessary to relatively rotate the pen cap 200 and the pen body 100, the problem that there is an angle between the suction surface of the pen cap 200 and the suction surface of the pen body 100 can be avoided, that is, the problem that the positions of the suction surface of the pen cap and the suction surface of the pen body are relatively offset can be avoided, which is beneficial to improving the flatness of the suction surface of the stylus pen, thereby improving the assembly effect of the stylus pen. Furthermore, the problems such as the poor suction effect between the stylus pen and the electronic device and the falling off of the protective layer on the surface of the stylus pen can be alleviated.

[0036] Optionally, the pen cap 200 includes a first cap body 210 and a second cap body 220. The second cap body 220 includes a first segment accommodated in the first cap body 210 and a second segment extending outside the first cap body 210;

[0037] The first elastic member 230 is disposed between the first cap body 210 and the second cap body 220. The first elastic member 230 includes a protrusion, and the protrusion protrudes from the outer side wall of the second segment;

[0038] When the pen cap 200 is inserted into the pen body 100, the second segment is inserted into the pen body 100 along the open end, and the protrusion is snapped into the card slot 110.

[0039] Among them, the first cap body 210 can be a hollow cap body with one end open, the second cap body 220 can be a columnar cap body, and the first cap body 210 is sleeved on the first segment of the second cap body 220. The second segment of the second cap body 220 is inserted into the pen body 100, and the end face of the first cap body 210 is in contact with the end face of the open end. In this way, the compactness of the touch pen structure can be improved.

[0040] A part of the first elastic member 230 can be located between the first cap body 210 and the second cap body 220 to fix the first elastic member 230 to the pen cap 200. At the same time, another part of the first elastic member 230 can extend out of the first cap body 210, and the part of the first elastic member 230 extending out of the first cap body 210 can include a protrusion, and the protrusion protrudes from the outer side wall of the second segment. In this way, during the process of inserting the pen cap 200 into the pen body 100, the protrusion of the first elastic member 230 can be inserted into the card slot 110 of the pen body 100, so as to realize the snap connection between the first elastic member 230 and the pen body 100.

[0041] It can be understood that the first cap body 210 and the second cap body 220 are fixedly connected relatively. For example, the first cap body 210 and the second cap body 220 can be bonded. In addition, the first elastic member 230 can also be fixedly connected to the pen cap 200 by means of bonding or other connection methods.

[0042] In this embodiment, by inserting the first segment of the second cap body 220 into the first cap body 210, and at the same time, inserting the second segment of the second cap body 220 into the pen body 100 and forming a protrusion on the surface of the second segment, in this way, the stability of the connection between the pen cap 200 and the pen body 100 can be improved, and at the same time, the joint effect at the connection between the pen cap 200 and the pen body 100 can also be improved.

[0043] Optionally, the protrusion includes a first protrusion portion 233 and a second protrusion portion 234. The first protrusion portion 233 is located at the first end 231 of the first elastic member 230, and the second protrusion portion 234 is located at the second end 232 of the first elastic member 230. The first protrusion portion 233 and the second protrusion portion 234 are located on two opposite sides of the second cap body 220;

[0044] The card slot 110 includes a first card slot and a second card slot, and the first card slot and the second card slot are arranged opposite to each other;

[0045] Wherein, when the pen cap 200 is inserted into the pen body 100, the first protrusion 233 is snap-fitted with the first card slot, and the second protrusion 234 is snap-fitted with the second card slot.

[0046] It can be understood that the first protrusion 233 and the second protrusion 234 can be located at any two different positions on the outer wall of the second segment. For example, the first protrusion 233 and the second protrusion 234 can be arranged at intervals along the length direction of the second segment, or the first protrusion 233 and the second protrusion 234 can be arranged at intervals along the circumferential direction of the second segment. In an embodiment of the present application, the first protrusion 233 and the second protrusion 234 are located on two opposite sides of the second cap body 220.

[0047] In this embodiment, by forming protrusions at both ends of the first elastic member 230 respectively, in this way, the pen cap 200 can be snap-fitted with the pen body 100 through the two protrusions respectively, which is beneficial to further improve the connection stability between the pen cap 200 and the pen body 100. At the same time, by arranging the first protrusion 233 and the second protrusion 234 on two opposite sides of the second cap body 220, that is, the first protrusion 233 and the second protrusion 234 are symmetrically distributed about the axis of the second cap body 220. In this way, when the protrusion is inserted into the card slot 110, the card slot 110 can respectively lock the positions of two opposite sides of the second cap body 220, which is beneficial to further improve the connection stability between the pen body 100 and the pen cap 200.

[0048] Optionally, the first elastic member 230 includes a first elastic arm, a connecting arm and a second elastic arm. The first elastic arm is opposite to the second elastic arm, and one end of the first elastic arm is connected to one end of the second elastic arm through the connecting arm;

[0049] Wherein, along the direction away from the connecting arm, the distance between the first elastic arm and the second elastic arm gradually increases.

[0050] Specifically, please refer to Figure 6 , the first elastic member 230 is an arch-shaped elastic sheet, and one end of the second cap body 220 facing away from the open end is embedded in the first elastic member 230. When the first cap body 210 is sleeved on the second cap body 220, the first elastic member 230 is limited between the first cap body 210 and the second cap body 220.

[0051] The distance between the first elastic arm and the second elastic arm gradually increases in the direction away from the connecting arm may mean that when the first elastic member 230 is in a free state, that is, not subjected to an external force, the distance between the first elastic arm and the second elastic arm gradually increases in the direction away from the connecting arm. Please refer to Figure 6 , when the pen cap 200 is inserted into the pen body 100, the first elastic arm and the second elastic arm are parallel. At this time, it is equivalent to deforming the first elastic arm and the second elastic arm inward respectively. Therefore, when the pen cap 200 is inserted into the pen body 100, the first elastic arm and the second elastic arm respectively have a tendency to move outward, so that the first protrusion 233 and the second protrusion 234 are pressed into the corresponding grooves to ensure the stability of the connection between the pen cap 200 and the pen body 100.

[0052] Optionally, the first end 231 of the first elastic member 230 is folded in a direction away from the second end 232 to form the first protrusion 233, and the first end 231 of the first elastic member 230 abuts against the inner wall of the first cap body 210;

[0053] The second end 232 of the first elastic member 230 is folded in a direction away from the first end 231 to form the second protrusion 234, and the second end 232 of the first elastic member 230 abuts against the inner wall of the first cap body 210.

[0054] In this embodiment, by folding the first end 231 of the first elastic member 230 in a direction away from the second end 232, the first protrusion 233 is formed. At the same time, by making the first end 231 of the first elastic member 230 abut against the inner side wall of the first cap body 210, in this way, the first end 231 of the first elastic member 230 has a tendency to deform in a direction away from the second end 232, that is, the first protrusion 233 has a tendency to deform in a direction away from the second end 232. In this way, during the process of inserting the pen cap 200 into the pen body 100, the first protrusion 233 can be inserted into the card slot 110 on the inner wall of the pen body 100. Correspondingly, by folding the second end 232 of the first elastic member 230 in a direction away from the first end 231, the second protrusion 234 is formed. At the same time, by making the second end 232 of the first elastic member 230 abut against the inner side wall of the first cap body 210, in this way, the second end 232 of the first elastic member 230 has a tendency to deform in a direction away from the first end 231, that is, the second protrusion 234 has a tendency to deform in a direction away from the first end 231. In this way, during the process of inserting the pen cap 200 into the pen body 100, the second protrusion 234 can be inserted into the card slot 110 on the inner wall of the pen body 100.

[0055] Optionally, a first groove 250 matching the shape of the first elastic member 230 is formed on the outer side wall of the second cap body 220, and the first elastic member 230 is embedded in the first groove 250.

[0056] Please refer to Figure 8 , the first groove 250 can be a "U"-shaped groove formed on the surface of the second cap body 220, and the first elastic member 230 is embedded in the "U"-shaped groove. It can be understood that when the first elastic member 230 is embedded in the first groove 250, the first protrusion 233 and the second protrusion 234 of the first elastic member 230 protrude out of the first groove 250, and other positions of the first elastic member 230 are located in the first groove 250.

[0057] In this embodiment, by forming the first groove 250 on the surface of the second cap body 220 and embedding the first elastic member 230 in the first groove 250, since the first cap body 210 can close a part of the notch of the first groove 250, therefore, the groove wall of the first groove 250 and the first cap body 210 can jointly limit the first elastic member 230 in the first groove 250, so as to further ensure that the position of the first elastic member 230 is relatively fixed.

[0058] Optionally, the pen further includes a circuit module. A receiving cavity is formed by enclosing between the pen body and the pen cap, and the circuit module is disposed in the receiving cavity;

[0059] The pen body 100 includes a metal pen tube. The first cap body 210 is an insulating cap body, and the second cap body 220 is a cap body with electrical conductivity. The circuit module includes a battery 400 and a circuit board 300;

[0060] The first electrode of the battery 400 is electrically connected to the circuit board 300, the second electrode of the battery 400 is electrically connected to the second cap body 220, the second cap body 220 is electrically connected to the first elastic member 230, and the protrusion presses against the inner wall of the card slot 110 to electrically conduct the first elastic member 230 and the pen body 100, and the pen body 100 is electrically connected to the circuit board 300.

[0061] The above circuit module can be the same as the internal circuit modules of various types of styluses or capacitive pens in the prior art. This application places no restrictions on the specific structure and internal circuit of the circuit module.

[0062] Specifically, the pen body 100 and the second cap body 220 can be made of conductive metal materials respectively, and the first cap body 210 can be made of insulating materials. For example, the pen body 100 and the second cap body 220 can be made of copper or aluminum materials respectively, and the first cap body 210 can be made of plastic materials.

[0063] Among them, the circuit board 300 can include a first terminal 310 and a second terminal 320. The first terminal 310 is electrically connected to the first electrode of the battery 400, and the second terminal 320 is electrically connected to the inner wall of the pen body 100. The first terminal 310 and the second terminal 320 can respectively form two power supply terminals of the circuit board 300. Among the first terminal 310 and the second terminal 320, one is used to connect the positive power supply, and the other is used to connect the negative power supply to supply power to the circuit board 300. Correspondingly, among the first electrode and the second electrode, one is the positive electrode and the other is the negative electrode.

[0064] The above first terminal 310 can be in contact with the first electrode to achieve electrical connection between the first terminal 310 and the first electrode. In addition, the first terminal 310 and the first electrode can also be electrically connected through an electrical connector. Correspondingly, the second electrode can be in contact with the second cap body 220, or be electrically connected through an electrical connector. The second terminal 320 can be in contact with the inner wall of the pen body 100, or be electrically connected through an electrical connector.

[0065] It is understandable that the first elastic member 230 is a conductive elastic member, and the first elastic member 230 is in contact with the second cap body 220 and the pen body 100 respectively, so as to realize the conduction of the second cap body 220 and the pen body 100 through the first elastic member 230.

[0066] In this embodiment, by electrically connecting the first terminal 310 of the circuit board 300, the first electrode of the battery 400, the second electrode of the battery 400, the second cap body 220, the first elastic member 230, the pen body 100, and the second terminal 320 of the circuit board 300 in sequence, a closed loop is formed, so that the first terminal 310 and the second terminal 320 are respectively connected to the positive and negative electrodes of the battery 400, so as to realize the power supply of the circuit board 300 by the battery 400. In addition, since the first cap body 210 is an insulating cap body, relative insulation of the second cap body 220 can be realized.

[0067] Optionally, the pen further includes a second elastic member 500 with conductive properties, and the second elastic member 500 is located between the second electrode and the second cap body 220;

[0068] When the pen cap 200 is inserted into the pen body 100, the second elastic member 500 is in an elastic deformation state to conduct the second electrode and the second cap body 220.

[0069] Specifically, the second elastic member 500 can be various types of springs. For example, please refer to Figure 6 , the second elastic member 500 can be a pagoda spring. The elastic deformation state can refer to an elastic compression state.

[0070] In this embodiment, by arranging the second elastic member 500 in a compressed state between the second electrode and the second cap body 220, in this way, the second elastic member 500 can not only improve the electrical connection stability between the second electrode and the second cap body 220, but also, under the action of the elastic force of the second elastic member 500, the first electrode of the battery 400 can press against the first terminal 310, thereby improving the electrical connection stability between the first electrode and the first terminal 310.

[0071] Optionally, an insulating layer is provided on the outer surface of the pen body 100.

[0072] Among them, the insulating layer can be an insulating film sprayed on the surface of the pen body 100. For example, the surface of the pen body 100 is painted. In addition, the insulating layer can also be an insulating oxide layer. For example, the pen body 100 can be subjected to insulating anodic oxidation treatment, so as to form an insulating oxide layer on the pen body 100.

[0073] In this embodiment, by providing an insulating layer on the outer surface of the pen body 100, it is beneficial to avoid the problem of electric leakage of the stylus pen.

[0074] Optionally, a first plane 120 arranged along the length direction of the pen body 100 is provided on the outer side wall of the pen body 100, and a second plane 240 arranged along the length direction of the pen cap 200 is provided on the outer side wall of the pen cap 200. At least one of the pen body 100 and the pen cap 200 is provided with a magnetic member 270 therein.

[0075] When the pen cap 200 is inserted into the pen body 100, the first plane 120 is aligned with the second plane 240.

[0076] Specifically, when the pen cap 200 includes a first cap body 210 and a second cap body 220, the second plane 240 may be provided on the outer side wall of the first cap body 210. In addition, a second groove 260 may be formed on the surface of the second cap body 220, and the magnetic member 270 may be embedded in the second groove 260. In this way, the stylus pen can be attracted to the electronic device through the magnetic member 270. Among them, the magnetic member 270 may be a magnet of various shapes.

[0077] Further, the notch of the second groove 260 may be arranged facing the second plane 240. In this way, the distance between the magnetic member 270 and the second plane 240 can be reduced. Since the second plane 240 is in contact with the electronic device when the stylus pen and the electronic device are in the attracted state, such an arrangement can reduce the distance between the magnetic member 270 and the electronic device in the attracted state, thereby increasing the magnetic force between the magnetic member 270 and the electronic device to improve the attraction effect between the stylus pen and the magnetic member 270.

[0078] Another embodiment of the present application provides an electronic device, and the electronic device includes the pen described in the above embodiment.

[0079] It can be understood that one relatively flat side surface of the electronic device can be set as the attraction surface, and a magnetic member can be embedded in the attraction surface of the electronic device to realize the attraction connection between the electronic device and the stylus pen.
