[0048] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0049] Styluses are used in electronic devices such as smartphones and tablets. The stylus consists of a pen tip, a force transmission rod, and a sensor. One end of the force transmission rod is connected to the pen tip, and the other end is connected to the sensor. When operating the stylus, the pressure applied to the pen tip is directly transmitted to the force transmission rod. The sensor connected to the force transmission rod can sense the pressure on the force transmission rod, thereby achieving control of the writing force. However, when the pen tip falls or is subjected to great pressure, the sensor will fall off or be damaged as the force transmission rod is subjected to great impact, resulting in sensing failure.

[0050] In view of this, the first embodiment of the present invention provides a stylus pen 10, which can effectively reduce the situation where the sensor 500 fails to sense. Figures 1 to 9 The stylus pen 10 according to the embodiment of the present application is introduced. Specifically, the stylus pen 10 includes a pen tip assembly 100, a pen housing 200, a bracket 300, a spring 400 and a sensor 500.

[0051] Reference Figures 1 to 3 First, the pen tip assembly 100 is introduced. The pen tip assembly 100 can contact the screen of the electronic device to achieve writing. Next, the pen housing 200 is introduced. The pen housing 200 can define a cavity 210, and the cavity 210 can accommodate various structural components and functional components. In order to facilitate the description and understanding of the relative arrangement direction of the pen housing 200 and the pen tip assembly 100, a first direction X is defined. Figure 4 The first direction X is a left-right direction. The pen housing 200 and the pen tip assembly 100 are arranged opposite to each other along the first direction X.

[0052] Reference Figure 2 and Figure 3 The bracket 300 is introduced below. The bracket 300 is used to carry components such as the circuit board 630. The bracket 300 is connected to the pen tip assembly 100, that is, the bracket 300 can transmit the pressure on the pen tip assembly 100. The bracket 300 can be accommodated in the cavity 210 of the pen housing 200. The specific configuration of the bracket 300 can refer to the relevant known technology.

[0053] Reference Figures 2 to 6The following describes the specific arrangement of the spring 400, which is used to transmit the pressure on the bracket 300. The spring 400 is arranged in the cavity 210 of the pen housing 200, and its specific arrangement position can be determined according to actual conditions. The spring 400 includes a first part 410 and a second part 420 connected to each other. Figure 6 As a reference, the portion of the spring sheet 400 located on the right side and arranged vertically may be the first portion 410, and the portion of the spring sheet 400 located in the middle and arranged horizontally may be the second portion 420. The first portion 410 may be connected to the bracket 300, and the second portion 420 may be connected to the pen housing 200.

[0054] It should be noted that the first portion 410 of the spring 400 is bent relative to the second portion 420. In some embodiments, the first portion 410 and the second portion 420 may be arranged vertically. In other embodiments, the first portion 410 and the second portion 420 may also be arranged at other non-vertical angles.

[0055] Reference Figures 4 to 6 The sensor 500 can sense the pressure on the pen tip assembly 100. The specific configuration of the sensor 500 is described below. The sensor 500 can be connected to the first portion 410 of the spring 400.

[0056] Reference Figure 4 , the specific sensing process of the sensor 500 is described below. After the pen tip assembly 100 is pressurized, the bracket 300 connected to the pen tip assembly 100 can transmit the pressure of the pen tip assembly 100. The first part 410 of the spring 400 is connected to the bracket 300, and the second part 420 is connected to the pen housing 200. The first part 410 is bent relative to the second part 420. Therefore, the first part 410 connected to the sensor 500 can be elastically deformed relative to the second part 420, so that the sensor 500 senses the pressure of the pen tip assembly 100 and realizes precise control of writing.

[0057] In the technical solution of the utility model, the stylus pen 10 includes a pen tip assembly 100, a pen housing 200, a bracket 300, a spring 400 and a sensor 500. In the prior art, the two ends of the force transmission rod are respectively connected to the pen tip and the sensor, that is, the pressure on the pen tip will be directly transmitted to the sensor via the force transmission rod. When the pressure is too large, the sensor is easy to fall off or be damaged, resulting in sensing failure. In this solution, the stylus pen 10 is additionally provided with a spring 400, and the spring 400 includes a first part 410 and a second part 420 that are connected to each other. The first part 410 is connected to the bracket 300, and the second part 420 is connected to the pen housing 200. The first part 410 is bent relative to the second part 420. The sensor 500 is connected to the bracket 300 through the first part 410 of the spring 400. Furthermore, after the pen tip assembly 100 is pressurized, the first part 410 of the spring piece 400 can be elastically deformed relative to the second part 420. Therefore, the sensor 500 of the present solution can obtain the pen tip pressure by detecting the deformation of the spring piece 400. Compared with the solution in the prior art in which the sensor is directly rigidly connected to the bracket, the spring piece 400 of the present solution can be elastically deformed after being pressurized to provide a buffer for the sensor 500, which can ensure the stability of the assembly connection of the sensor 500, improve the reliability of the sensor 500 in detecting pressure, and effectively reduce the occurrence of sensing failure.

[0058] Reference Figures 4 to 6 , the specific arrangement of the first part 410 of the spring 400 is described below. In some embodiments, along the first direction X, the first part 410 can be arranged on the side of the second part 420 away from the pen tip assembly 100. In other embodiments, along the first direction X, the first part 410 can also be arranged on the side of the second part 420 close to the pen tip assembly 100. Some embodiments of the present application are described by taking the example that the first part 410 is arranged on the side of the second part 420 away from the pen tip assembly 100.

[0059] The first portion 410 includes a first side wall 411. It can be understood that the first side wall 411 can be a side wall of the first portion 410 along the first direction X. Figure 6 The first side wall 411 may be a side wall on the left side of the first part 410, or may be a side wall on the right side of the first part 410. Some embodiments of the present application are described by taking the first side wall 411 as the side wall on the right side of the first part 410. The first side wall 411 is a plane wall, and the sensor 500 is connected to the first side wall 411.

[0060] Compared with the solution in the prior art in which the sensor is connected to the arc surface of the force transmission rod, the sensor 500 in this solution is connected to the plane wall of the spring piece 400, which can effectively increase the contact area between the spring piece 400 and the sensor 500, further improve the stability of pressure detection, and effectively reduce the occurrence of sensing failure.

[0061] Reference Figures 4 to 6 , the assembly connection arrangement between the first part 410 and the bracket 300 is described below. In some embodiments, the first part 410 includes a second side wall 412 opposite to the first side wall 411, Figure 6 As a reference, the first side wall 411 can be the side wall on the right side of the first part 410, and the second part 420 can be the side wall on the left side of the first part 410. The second side wall 412 is connected to the end of the bracket 300 away from the pen tip assembly 100, that is, after the bracket 300 is subjected to the pressure of the pen tip assembly 100, it can directly transmit the force to the second side wall 412 of the first part 410, and because the second part 420 is fixedly connected to the pen housing 200, the first part 410 can be elastically deformed, so that the sensor 500 senses the pressure of the pen tip assembly 100 to achieve detection. This solution can effectively improve the reliability of the detection of the sensor 500.

[0062] Reference Figures 4 to 6 In some embodiments, the spring piece 400 includes a third portion 430. The third portion 430 is disposed on a side of the second portion 420 away from the first portion 410. Figure 6 The orientation in is used as a reference, that is, the left part of the spring sheet 400 can be the third part 430, and the right part of the spring sheet 400 can be the first part 410. The third part 430 is connected to the bracket 300. In addition, the third part 430 is bent relative to the second part 420, and the spring sheet 400 is configured so that the third part 430 can be elastically deformed relative to the second part 420 after the pen tip assembly 100 is compressed. This solution can further improve the stability of the connection between the spring sheet 400 and the bracket 300, thereby ensuring the reliability of the detection of the sensor 500.

[0063] Reference Figures 3 to 5 , the specific setting of the circuit component 600 of the stylus 10 is described below. In some embodiments, the stylus 10 includes a circuit component 600. The circuit component 600 includes a transmitting electrode 610 and an electrode tube 620 connected to each other, and also includes a circuit board 630. It can be understood that the transmitting electrode 610 can generate an electric field on the screen of the electronic device. When the user touches the screen with the stylus 10, the transmitting electrode 610 will send an electric field signal to the surface of the screen, thereby generating a capacitive coupling effect with the sensing electrode in the screen. The electrode tube 620 can protect the transmitting electrode 610 and ensure that the electric field signal can be accurately transmitted to the touch screen while avoiding the influence of external interference on the electric field signal. The circuit board 630 can serve as the control center in the stylus 10, which can be responsible for receiving, processing and transmitting signals from the transmitting electrode 610. The circuit board 630 includes electronic components such as a microprocessor, a sensor 500, and an amplifier, through which the control and data processing of the stylus 10 can be realized.

[0064] Reference Figure 4 , Figure 7 and Figure 8 The circuit assembly 600 further includes a first electrical connector 640. The first electrical connector 640 includes a first connecting portion 641 and a second connecting portion 642 connected to each other. The first connecting portion 641 can be connected to an end of the electrode tube 620 that is away from the emitting electrode 610, and the second connecting portion 642 can be connected to the circuit board 630, so that the emitting electrode 610 and the circuit board 630 are connected.

[0065] The prior art uses a conductor in the form of a lead such as a wire to connect the emitting electrode 610 and the circuit board 630. Since the wire needs to be electrically connected to other electronic components through welding, the reliability of the electrical connection depends on the stability of the welding process. In order to ensure the reliability of the electrical connection, the difficulty of the welding process will be greatly increased, making the overall assembly of the stylus pen 10 complicated. This solution uses a first electrical connector 640 to connect the emitting electrode 610 and the circuit board 630, which can greatly reduce the difficulty of assembling the stylus pen 10 and improve the assembly efficiency.

[0066] Reference Figure 5 and Figure 8 , the specific structure of the first electrical connector 640 is introduced below. In some embodiments, the first connection portion 641 of the first electrical connector 640 is provided with a groove 6411, and the first electrical connector 640 is configured to be elastically deformable so that the electrode tube 620 is abutted against the groove 6411. In this solution, the end of the electrode tube 620 away from the pen tip assembly 100 can be abutted against the groove 6411 of the elastically bent first connection portion 641, that is, the stability of the connection between the electrode tube 620 and the first electrical connector 640 can be guaranteed, and the elastically deformed first connection portion 641 can also provide a buffer for the electrode tube 620 to prevent the electrode tube 620 from being damaged by high pressure.

[0067] Reference Figures 3 to 5 , the specific configuration of the circuit assembly 600 of the stylus pen 10 is described below. In some embodiments, the stylus pen 10 includes the circuit assembly 600. The circuit assembly 600 includes a receiving electrode and a circuit board 630. The receiving electrode can receive an electric field signal sent by a transmitting electrode 610 of a touch screen in an electronic device. When a user uses the stylus pen 10 to operate on the touch screen, the receiving electrode senses the changes in the electric field signal generated by the transmitting electrode 610 and transmits these signals to the circuit board 630 for processing.

[0068] Reference Figure 4 , Figure 7 and Fig. 9The circuit assembly 600 includes a second electrical connector 650, and the second electrical connector 650 includes a third connector 651 and a fourth connector 652 connected to each other. The third connector 651 is connected to the receiving electrode, and the fourth connector 652 is connected to the circuit board 630, so that the receiving electrode and the circuit board 630 are connected.

[0069] The prior art uses a conductor in the form of a lead such as a wire to connect the circuit board 630 and the receiving electrode. Since the wire needs to be electrically connected to other electronic components through welding, the reliability of the electrical connection depends on the stability of the welding process. In order to ensure the reliability of the electrical connection, the difficulty of the welding process will be greatly increased, making the overall assembly of the stylus 10 complicated. This solution uses a second electrical connector 650 to connect the circuit board 630 and the receiving electrode, which can further reduce the difficulty of assembling the stylus 10 and improve the assembly efficiency.

[0070] Reference Figure 5 and Fig. 9 In some embodiments, the fourth connection portion 652 of the second electrical connector 650 is provided with a first protrusion 6521, and the circuit board 630 is provided with a first opening 631, and the first opening 631 is adapted to the arrangement of the first protrusion 6521. In a direction perpendicular to the first direction X, the first protrusion 6521 penetrates the first opening 631. It should be noted that the fourth connection portion 652 can also be provided with a plurality of first protrusions 6521, and the circuit board 630 is provided with a plurality of first openings 631. Among them, each first protrusion 6521 is correspondingly penetrated by each first opening 631. Compared with the solution of welding the circuit board with wires, this solution can improve the stability of the assembly connection between the circuit board 630 and the receiving electrode, and improve the assembly efficiency.

[0071] Reference Figures 2 to 5 , Figure 7 In some embodiments, the stylus pen 10 includes a first pad 700 and a second pad 800 that are arranged opposite to each other. The circuit board 630 is at least partially disposed between the first pad 700 and the second pad 800, and the second pad 800 is located on the side of the first pad 700 that is away from the bracket 300. It can be understood that the first pad 700 can be carried by the bracket 300. The second pad 800 can press the second electrical connector 650 against the circuit board 630. Specifically, a fastener can be additionally provided, and the second electrical connector 650 can be pressed against the circuit board 630 by tightening the fastener. By providing the first pad 700 and the second pad 800, this solution can prevent the second electrical connector 650 from loosening from the circuit board 630, and can further improve the stability of the assembly connection between the second electrical connector 650 and the circuit board 630.

[0072] Reference Figure 7 and Fig. 9In some embodiments, the fourth connection portion 652 of the second electrical connector 650 is provided with a second protrusion 6522. The second protrusion 6522 is arranged opposite to the first protrusion 6521. The first protrusion 6521 at least partially extends into the first pad 700, that is, it can improve the stability of the connection between the second electrical connector 650 and the first pad 700, and prevent the second electrical connector 650 and the first pad 700 from being misaligned along the first direction X. It should be noted that the first protrusion 6521 can only extend into the first pad 700, or it can penetrate the first pad 700. Some embodiments of the present application are described by taking the first protrusion 6521 penetrating the first pad 700 as an example.

[0073] Reference Figure 7 , the second protrusion 6522 at least partially extends into the second pad 800, which can improve the stability of the assembly connection between the second electrical connector 650 and the second pad 800. It can be understood that the second protrusion 6522 only extends into the second pad 800, or can pass through the second pad 800. Some embodiments of the present application are described by taking the second protrusion 6522 passing through the second pad 800 as an example.

[0074] Reference Figure 5 and Figure 7 In some embodiments, the stylus pen 10 includes a circuit assembly 600. The circuit assembly 600 includes an emitting electrode 610 and an electrode tube 620 connected to each other, and also includes a circuit board 630 and a first electrical connector 640. The first electrical connector 640 is at least partially disposed between the first pad 700 and the second pad 800. The specific location of the first electrical connector 640 can be determined according to actual conditions. The second pad 800 is configured to press the first electrical connector 640 to the circuit board 630, that is, the present solution can effectively improve the stability of the assembly connection between the first electrical connector 640 and the circuit board 630.
