Description

Technical Field

[0001] The utility model relates to the technical field of electronic touch devices, and in particular to a touch pen and an electronic device component. Background Art

[0022] Compared with the prior art, the beneficial effects of the present invention include:

[0023] In the technical solution of the present invention, the stylus includes a pen tip assembly, a pen housing, a bracket, an L-shaped spring, and a sensor. In the prior art, the two ends of the bracket are connected to the pen tip and the U-shaped spring, respectively. The two end plates of the U-shaped spring will deform after being subjected to the pressure from the pen tip transmitted through the bracket, while the sensor is only connected to one end plate of the U-shaped spring. Therefore, the sensor has poor accuracy in pressure detection. In this solution, the stylus includes an L-shaped spring, the first plate of the L-shaped spring is connected to the pen housing, the second plate is connected to the bracket, the first plate is bent relative to the second plate, and the sensor is connected to the first plate. That is, the deformation of the L-shaped spring in this solution is concentrated on the first plate. The sensor of this solution can obtain the pen tip pressure by detecting the deformation of the first plate, thereby ensuring the accuracy of pressure detection. Furthermore, because the thickness of the second plate in the L-shaped spring is greater than that of the first plate, the deformation caused by pressure can be more concentrated on the first plate, which has a weak structure, further ensuring the accuracy of pressure detection. In addition, compared with the solution that requires multiple welding points for the assembly of the U-shaped spring clip with the bracket and the pen shell, the L-shaped spring clip of this solution has fewer welding points for the assembly connection with the bracket and the pen shell, which can effectively reduce welding costs and reduce quality problems caused by unreliable welding. It can also offset the anisotropy caused by the spring clip welding to a certain extent, thereby improving the measurement accuracy of the stylus in different grip states.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0050] Styluses are used in electronic devices such as smart phones and tablet computers. Existing styluses include a pen tip, a bracket, a pen shell, a U-shaped spring and a sensor. One end of the bracket is connected to the pen tip, and the other end is connected to the U-shaped spring. The U-shaped spring includes two end plates and a middle plate, and both sides of the middle plate are connected to an end plate respectively. The middle plate is connected to the pen shell, and the touch sensor is provided on one end plate. When operating the stylus, the pressure applied to the pen tip will be transmitted to the bracket, and the U-shaped spring connected to the bracket will deform relative to the shell, so that the sensor senses the pressure of the pen tip to control the writing force. In the related art, since the end plates on both sides of the U-shaped spring will deform under pressure, and the sensor is only arranged on one end plate of the U-shaped spring, the accuracy of the sensor in pressure detection is poor.

[0051] In view of this, the first embodiment of the present invention proposes a stylus pen 10, which can ensure the accuracy of pressure detection. Figures 1 to 9 The stylus pen 10 according to an 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, an L-shaped spring 400, and a sensor 500.

[0052] Reference Figures 1 to 4First, we will introduce the pen tip assembly 100. The pen tip assembly 100 can contact the screen of the electronic device to enable writing. Next, we will introduce the pen housing 200. The pen housing 200 can define a cavity 210, which can accommodate various functional components and various structural components. To facilitate the description and understanding of the relative arrangement between the pen housing 200 and the pen tip assembly 100, a first direction X is defined. The pen housing 200 and the pen tip assembly 100 are arranged relative to each other along the first direction X. Figure 4 The orientation in is used as a reference, that is, the pen housing 200 and the pen tip assembly 100 are arranged relative to each other along the left-right direction.

[0053] Reference Figures 2 to 4 Next, we will introduce the bracket 300 . The bracket 300 can support components such as the circuit assembly 600 . The bracket 300 is connected to the pen tip assembly 100 , meaning that the bracket 300 can transmit the pressure exerted on the pen tip assembly 100 . The bracket 300 can be accommodated in the cavity 210 of the pen housing 200 .

[0054] Reference Figures 2 to 7 The specific configuration of the L-shaped spring piece 400 is described below. The L-shaped spring piece 400 can be disposed in the cavity 210 of the pen housing 200. The L-shaped spring piece 400 includes a first plate 410 and a second plate 420 connected to each other. Figure 7 Using the orientation in FIG as a reference, the horizontally arranged plate on the left side may be the first plate 410, and the vertically arranged plate on the right side may be the second plate 420. The first plate 410 can be connected to the pen housing 200, and the second plate 420 can be connected to the bracket 300. Furthermore, the first plate 410 is bent relative to the second plate 420. The specific bending angle between the first and second plates 410 and 420 can be determined based on actual conditions. It should be noted that the thickness of the second plate 420 can be greater than that of the first plate 410.

[0055] Reference Figure 2 and Figure 6 , the sensor 500 can sense the pressure exerted on the pen tip assembly 100. Specifically, the sensor 500 can be connected to the first plate 410 of the L-shaped spring clip 400. The specific sensing process of the sensor 500 is described below. When the pen tip assembly 100 is under pressure, the bracket 300 connected to the pen tip assembly 100 can transmit the pressure of the pen tip assembly 100. The first plate 410 of the L-shaped spring clip 400 is connected to the pen housing 200, and the second plate 420 is connected to the bracket 300. The first plate 410 is bent relative to the second plate 420, that is, the first plate 410 connected to the sensor 500 can undergo elastic deformation relative to the second plate 420, thereby enabling the sensor 500 to sense the pressure exerted on the pen tip assembly 100 and achieve precise control of the writing force.

[0056] In the technical solution of the present invention, a stylus pen 10 includes a pen tip assembly 100, a pen housing 200, a bracket 300, an L-shaped spring 400, and a sensor 500. In the prior art, the bracket connects the pen tip and the U-shaped spring at both ends, respectively. Both end plates of the U-shaped spring deform when subjected to pressure from the pen tip transmitted through the bracket, while the sensor is only connected to one end plate of the U-shaped spring. Consequently, the sensor's pressure detection accuracy is poor. In contrast, in the present solution, the stylus pen 10 includes an L-shaped spring 400. A first plate 410 of the L-shaped spring 400 is connected to the pen housing 200, and a second plate 420 is connected to the bracket 300. The first plate 410 is bent relative to the second plate 420, and the sensor 500 is connected to the first plate 410. In other words, in this solution, the deformation of the L-shaped spring 400 is concentrated on the first plate 410. The sensor 500 of this solution can detect the pen tip pressure by detecting the deformation of the first plate 410, ensuring accurate pressure detection. Furthermore, because the thickness of the second plate 420 in the L-shaped spring clip 400 is greater than that of the first plate 410, the deformation caused by pressure is more concentrated on the structurally weaker first plate 410, further ensuring the accuracy of pressure detection. Furthermore, compared to the U-shaped spring clip, which requires multiple welds to assemble the bracket and pen housing, this solution uses fewer welds to assemble the L-shaped spring clip 400 with the bracket 300 and pen housing 200. This effectively reduces welding costs and quality issues caused by weak welds. It also offsets the anisotropy caused by the spring clip welding to a certain extent, improving the measurement accuracy of the stylus 10 in different grip positions.

[0057] Reference Figure 7 , the specific settings of the first plate body 410 and the second plate body 420 are introduced below. The second plate body 420 includes a main body 421 and a side portion 422 that are connected to each other. The main body 421 can be connected to the first plate body 410, and the side portion 422 can be spaced apart from the first plate body 410. In some embodiments, the thickness of the side portion 422 can be greater than the thickness of the first plate body 410. In other embodiments, the thickness of the main body 421 can be greater than the thickness of the first plate body 410. In other embodiments, the thickness of each of the main body 421 and the side portion 422 can be greater than the thickness of the first plate body 410. The above-mentioned setting adopted in this solution can make the deformation of the L-shaped spring piece 400 more concentrated on the first plate body 410, thereby improving the accuracy of pressure detection.

[0058] Reference Figure 6 and Figure 7 The following describes the specific connection arrangement between the bracket 300 and the second plate 420. In some embodiments, the relative positions of the L-shaped spring 400 and the bracket 300 are first described. Specifically, along the first direction X, the first plate 410 is located on a side of the second plate 420 facing away from the bracket 300.

[0059] Reference Figure 7 , the second plate 420 may be provided with an opening 423, and the opening 423 may be a circular hole. Figure 6 The bracket 300 can be provided with a protrusion 310, which can be adapted to fit within the opening 423. The protrusion 310 can be formed through the opening 423 in a direction perpendicular to the first direction X. In the prior art, the U-shaped spring clip requires a jig for positioning when assembled and connected to the bracket. In this solution, the protrusion 310 of the bracket 300 can be positioned by passing through the opening 423 of the second plate 420. This eliminates the need for jigs, simplifies the assembly process, and effectively improves the processing efficiency of the stylus 10.

[0060] Reference Figure 3 and Figure 6 In some embodiments, the protrusion 310 may be provided with a connection hole 311, and the axis of the connection hole 311 may coincide with the axis of the opening 423. Along a direction perpendicular to the first direction X, the connector 900 may penetrate the connection hole 311 and the opening 423, thereby connecting the second plate 420 and the bracket 300. It is understood that the connector 900 may be a screw or bolt. Compared to the solution of welding the spring clip to the bracket, the connector 900 of this solution can achieve a detachable connection between the second plate 420 and the bracket 300 and ensure the stability of the assembled connection.

[0061] Reference Figure 6 and Figure 7 , the specific configuration of the first plate 410 of the L-shaped spring 400 is described below. In some embodiments, it can be understood that along the first direction X, the first plate 410 is located on the side of the second plate 420 away from the pen tip assembly 100. The first plate 410 includes a first side wall 411 away from the second plate 420. Figure 7 With reference to the direction in FIG, the wall surface of the first plate body 410 close to the right side is the first side wall 411. The first side wall 411 may be a plane wall, and the sensor 500 may be connected to the first side wall 411.

[0062] 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 L-shaped spring clip 400, which can effectively increase the contact area between the spring clip and the sensor 500, improve the stability of pressure detection, and effectively reduce the occurrence of sensing failure.

[0063] Reference Figures 1 to 3, the specific configuration of the pen housing 200 is described below. In some embodiments, the pen housing 200 includes a peripheral housing 220 and an end plate 230 arranged relative to each other along a first direction X. The end plate 230 can be located on a side of the peripheral housing 220 close to the pen tip assembly 100. The connection relationship between the peripheral housing 220 and the end plate 230 is described below. Along a direction perpendicular to the first direction X, one end of the end plate 230 can be connected to the peripheral housing 220, and the other end can be spaced apart from the peripheral housing 220. It should be noted that the second side wall of the end plate 230 facing away from the pen tip assembly 100 can abut the bracket 300, that is, when the stylus pen 10 is dropped or the pen tip assembly 100 collides with an external object, the end plate 230 of the pen housing 200 can undergo elastic deformation relative to the peripheral housing 220, that is, it can provide a buffer for the pen tip assembly 100 and improve the drop resistance of the stylus pen 10.

[0064] Reference Figures 2 to 6 The following describes the specific configuration of the circuit assembly 600 of the stylus 10. In some embodiments, the stylus 10 includes the circuit assembly 600. The circuit assembly 600 comprises an interconnected transmitting electrode 610 and an electrode tube 620, as well as a circuit board 630. It will be appreciated 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 transmits an electric field signal to the screen surface, thereby generating a capacitive coupling effect with the sensing electrodes in the screen. The electrode tube 620 protects the transmitting electrode 610 and ensures that the electric field signal is accurately transmitted to the touch screen while preventing external interference from affecting the electric field signal. The circuit board 630 serves as the control center of the stylus 10, responsible for receiving, processing, and transmitting signals from the transmitting electrode 610. The circuit board 630 includes electronic components such as a microprocessor, sensor 500, and amplifier, which enable control and data processing of the stylus 10.

[0065] Reference Figure 3 、 Figure 5 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 that are interconnected. The first connecting portion 641 can be connected to the end of the electrode tube 620 that faces away from the emitting electrode 610, and the second connecting portion 642 can be connected to the circuit board 630, thereby establishing electrical connection between the emitting electrode 610 and the circuit board 630.

[0066] Conventional technology uses conductors, such as wires, to connect the emitter electrode to the circuit board. However, since the wires must be soldered to other electronic components for electrical connection, the reliability of the electrical connection depends on the stability of the soldering process. Ensuring this reliability significantly increases the difficulty of the soldering process, complicating the overall assembly of the stylus pen. This solution utilizes a first electrical connector 640 to connect the emitter electrode 610 to the circuit board 630, significantly reducing the difficulty of stylus pen 10 assembly and improving assembly efficiency.

[0067] Reference Figure 5 and Figure 8 The specific structure of the first electrical connector 640 is described below. In some embodiments, the first connecting portion 641 of the first electrical connector 640 is provided with a groove 6411, and the first electrical connector 640 is configured to elastically deform so that the electrode tube 620 abuts against the groove 6411. In this embodiment, the end of the electrode tube 620 facing away from the nib assembly 100 can abut against the groove 6411 of the elastically bent first connecting portion 641, thereby ensuring the stability of the connection between the electrode tube 620 and the first electrical connector 640. The elastically deformable first connecting portion 641 also provides a buffer for the electrode tube 620, preventing damage to the electrode tube 620 due to high pressure.

[0068] Reference Figures 3 to 6 The following describes the specific configuration of the circuit assembly 600 of the stylus 10. In some embodiments, the stylus 10 includes a circuit assembly 600. The circuit assembly 600 includes receiving electrodes and a circuit board 630. The receiving electrodes can receive electric field signals transmitted by transmitting electrodes 610 of a touch screen in an electronic device. When a user operates the stylus 10 on the touch screen, the receiving electrodes sense changes in the electric field signals generated by the transmitting electrodes 610 and transmit these signals to the circuit board 630 for processing.

[0069] Reference Figure 3 、 Figure 5 and Figure 9 The circuit assembly 600 includes a second electrical connector 650, which includes a third connecting portion 651 and a fourth connecting portion 652 connected to each other. The third connecting portion 651 is connected to the receiving electrode, and the fourth connecting portion 652 is connected to the circuit board 630, thereby conducting electricity between the receiving electrode and the circuit board 630.

[0070] Conventional technology uses conductors, such as wires, to connect the circuit board and the receiving electrode. However, since the wires must be soldered to other electronic components for electrical connection, the reliability of the electrical connection depends on the stability of the soldering process. Ensuring this reliability significantly increases the difficulty of the soldering process, complicating the overall assembly of the stylus. This solution uses a second electrical connector 650 to connect the circuit board 630 and the receiving electrode, further simplifying the assembly of the stylus 10 and improving assembly efficiency.

[0071] Reference Figure 5 and Figure 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 hole 631. The first hole 631 is adapted to fit the first protrusion 6521. The first protrusion 6521 passes through the first hole 631 in a direction perpendicular to the first direction X. It should be noted that the fourth connection portion 652 may also be provided with multiple first protrusions 6521, and the circuit board 630 may be provided with multiple first holes 631. Each first protrusion 6521 passes through each first hole 631 in a one-to-one correspondence. Compared to a solution using wire soldering to a circuit board, this solution can improve the stability of the assembly connection between the circuit board 630 and the receiving electrode, and improve assembly efficiency.

[0072] Reference Figures 2 to 6 In some embodiments, the stylus 10 includes a first pad 700 and a second pad 800 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 facing away from the bracket 300. It is understood that the first pad 700 can be supported 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 added, and the second electrical connector 650 can be pressed against the circuit board 630 by screwing 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.

[0073] Reference Figure 2 and Figure 9 In 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 disposed opposite to the first protrusion 6521. The first protrusion 6521 at least partially extends into the first pad 700, thereby improving the stability of the connection between the second electrical connector 650 and the first pad 700 and preventing misalignment between the second electrical connector 650 and the first pad 700 along the first direction X. It should be noted that the first protrusion 6521 may extend only into the first pad 700 or may pass through the first pad 700. Some embodiments of the present application are described using the example of the first protrusion 6521 passing through the first pad 700.

[0074] Reference Figure 2The second protrusion 6522 at least partially extends into the second pad 800, thereby improving the stability of the assembled connection between the second electrical connector 650 and the second pad 800. It is understood that the second protrusion 6522 may extend only into the second pad 800 or may pass through the second pad 800. Some embodiments of the present application are described using the example of the second protrusion 6522 passing through the second pad 800.

[0075] Reference Figures 2 to 4 In some embodiments, the stylus 10 includes a circuit assembly 600. The circuit assembly 600 includes an interconnected emitter electrode 610 and an electrode tube 620, a circuit board 630, and a first electrical connector 640. The first electrical connector 640 is at least partially disposed between a first backing plate 700 and a second backing plate 800.
