Description

Technical Field

[0001] This application relates to the field of terminal technology, and in particular to a stylus and electronic device component. Background Technology

[0002] As an input device, a stylus pen is often used in conjunction with electronic devices such as mobile phones, tablets, and writing tablets to facilitate accurate drawing, writing, and touch operations.

[0003] In related technologies, a stylus may include a pen body assembly and a sliding cover assembly. The sliding cover assembly is slidably disposed at the tail of the pen body assembly, which may have a charging port or other components. Sliding the cover assembly can either conceal or expose these components. The sliding cover assembly may include metal structural parts to improve its strength and lifespan. However, in related technologies, strong electrical interference at the stylus location can easily lead to malfunctions and other problems. Utility Model Content

[0004] This application provides a stylus and electronic device assembly. While the sliding cover assembly of the stylus has high strength and long service life, the failure rate of the stylus is also low.

[0005] A first aspect of this application provides a stylus, which includes a pen body assembly and a sliding cover assembly. The pen body assembly includes a head segment and a tail segment, located at opposite ends of the pen body assembly's axial direction. The tail segment has a grounding portion. The sliding cover assembly is disposed outside the tail segment and includes a metal structural member. The sliding cover assembly is slidably disposed on the tail segment via the metal structural member. The sliding cover assembly can slide along the axial direction of the pen body assembly between an open position away from the head segment and a closed position near the head segment. The metal structural member has an electrical connection portion. When the sliding cover assembly is in the closed position, the metal structural member is electrically connected to the grounding portion via the electrical connection portion.

[0006] The stylus provided in this application embodiment has a metal structural component that is electrically connected to a grounding part through an electrical connection part, thereby enabling grounding. This makes it less likely for the metal structural component to trip when the sliding cover assembly is in the closed position, even if there is strong electrical interference at the stylus. This helps to reduce the failure rate of the stylus while ensuring that the sliding cover assembly of the stylus has high strength and a long service life.

[0007] In one possible implementation, the metal structural component is provided with a first sliding cover magnet, and the tail structural section is provided with a pen body magnet. The electrical connection portion includes a closing contact portion. When the sliding cover assembly is in the closed position, the closing contact portion is pressed against the grounding portion under the magnetic force generated by the first sliding cover magnet and the pen body magnet, and the closing contact portion is in electrical contact with the grounding portion.

[0008] In this way, when the sliding cover assembly is in the closed position, the metal structural components can be grounded stably and reliably, which helps to reduce the failure rate of the stylus.

[0009] In one possible implementation, the closing contact portion includes a first closing contact sub-portion, and the grounding portion includes a first grounding sub-portion. The first grounding sub-portion and the first closing contact sub-portion are arranged along the axial direction of the pen body assembly, with the first grounding sub-portion located between the first closing contact sub-portion and the head structure segment. Along the axial direction of the pen body assembly, the projection of the first grounding sub-portion at least partially overlaps with the projection of the first closing contact sub-portion. When the sliding cover assembly is in the closed position, the first closing contact sub-portion is pressed against the first grounding sub-portion along the axial direction of the pen body assembly by the magnetic force generated by the first sliding cover magnet and the pen body magnet, and the first closing contact sub-portion and the first grounding sub-portion make electrical contact.

[0010] In this way, compared to frictional contact, the electrical contact when the first closing contact part is pressed against the first grounding part along the axial direction of the pen body assembly is more stable and reliable, making the grounding of the metal structural component more stable and reliable. Furthermore, the structure that grounds the metal structural component when the sliding cover assembly is in the closed position has less impact on the relative sliding between the sliding cover assembly and the tail section, allowing for smooth opening and closing of the sliding cover assembly while simultaneously grounding the metal structural component in the closed position. Additionally, the wear caused by the relative sliding between the sliding cover assembly and the tail section has less impact on the service life and contact effect of the first closing contact part and the first grounding part, resulting in a longer service life and more stable and reliable electrical contact.

[0011] In one possible implementation, the first grounding part is located at the end of the tail structure segment away from the head structure segment, and the first closing contact part is located on the side of the tail structure segment away from the head structure segment.

[0012] This design facilitates the first closing contact pressing against the first grounding contact when the sliding cover assembly is in the closed position. Furthermore, the placement of the first closing contact pressing against the first grounding contact has minimal impact on the overall structure of the stylus, promoting smooth opening and closing of the sliding cover assembly. Additionally, it allows for a longer sliding stroke in the sliding cover assembly.

[0013] For example, the metal structural member includes a sliding structure, which slides the metal structural member onto the tail section.

[0014] In one possible implementation, the first closed contact portion is fixedly connected to the sliding structure, and the first closed contact portion protrudes from the inner surface of the sliding structure.

[0015] In this way, the first closed contact part is more conveniently designed, facilitating the pressing of the first closed contact part against the first grounding part located at the end of the tail structure segment away from the head structure segment. Furthermore, the first closed contact part has less impact on the sliding of the metal structural components.

[0016] In one possible implementation, the tail section has a groove. The groove extends axially along the pen body assembly and passes through the end of the tail section away from the head section. A sliding structure passes through the groove and slides in engagement with it. The metal structural component is slidably positioned on the tail section via the sliding structure and the groove. A first closing contact is located on the side of the groove away from the head section.

[0017] This facilitates the smooth sliding of the sliding cover assembly via the slide groove while simultaneously achieving the crimping of the first closing contact and the first grounding contact. The first closing contact is less likely to affect the sliding of the sliding structure within the slide groove. Furthermore, it is convenient for the first closing contact to crimp the first grounding contact located at the end of the tail section away from the head section, while ensuring smooth opening and closing of the sliding cover assembly and preventing the sliding cover assembly from rotating relative to the tail section.

[0018] In one possible implementation, the inner side of the sliding structure has a first groove, and the first sliding cover magnet is fixedly disposed in the first groove.

[0019] In this way, the distance between the first sliding cover magnet and the pen body magnet is small, which generates a large magnetic force. At the same time, the setting of the first sliding cover magnet is less likely to affect the sliding structure relative to the tail structure segment.

[0020] In one possible implementation, the closing contact portion includes a second closing contact sub-portion, and the grounding portion includes a second grounding sub-portion. The second grounding sub-portion is located on the outer side of the tail structure segment, and the second closing contact portion is located on the inner side of the sliding structure. When the sliding cover assembly is in the closed position, at least a portion of the second closing contact sub-portion is opposite to the second grounding sub-portion along the radial direction of the pen body assembly. At least one of the second closing contact portion and the second grounding sub-portion undergoes elastic deformation under the action of the magnetic force generated by the first sliding cover magnet and the pen body magnet, so that the second closing contact sub-portion is pressed against the second grounding sub-portion, and the second closing contact portion and the second grounding sub-portion are in electrical contact.

[0021] In this way, when the sliding cover assembly is in the closed position, stable and reliable grounding of the metal structural component can be achieved through the electrical contact between the second closing contact and the second grounding contact. Furthermore, the structure that grounds the metal structural component when the sliding cover assembly is in the closed position has minimal impact on the relative sliding of the sliding cover assembly and the tail section, allowing for smooth opening and closing of the sliding cover assembly while simultaneously grounding the metal structural component when it is in the closed position.

[0022] In one possible implementation, along the radial direction of the pen body assembly, a first sliding cover magnet is fixedly disposed on the outside of a second closing contact portion, at least a portion of the second closing contact portion is opposite to the first sliding cover magnet, and at least a portion of the second grounding portion is opposite to the pen body magnet.

[0023] This allows the second closing contact portion to deform towards the second grounding portion when the sliding cover assembly is in the closed position, facilitating the second closing contact portion to press against the second grounding portion. Furthermore, the first sliding cover magnet is less likely to detach from the sliding structure.

[0024] In one possible implementation, the first sliding magnet has a first magnetic pole and a second magnetic pole, which are arranged axially along the pen body assembly. The pen body magnet has a third magnetic pole and a fourth magnetic pole, which are also arranged axially along the pen body assembly. The pen body magnet is located inside the first sliding magnet along the radial direction of the pen body assembly.

[0025] In this way, a magnetic force can be generated between the first sliding cover magnet and the pen body magnet along the axial direction and the radial direction of the pen body assembly. This facilitates the use of the magnetic force generated by the first sliding cover magnet and the pen body magnet to drive the sliding cover assembly to slide along the axial direction of the pen body assembly, thereby achieving automatic opening and closing after the sliding cover assembly slides to a preset position. It also facilitates the use of the magnetic force generated by the first sliding cover magnet and the pen body magnet to achieve the pressing of the electrical connection part and the grounding part in at least one direction of the axial and radial directions of the pen body assembly.

[0026] In one possible implementation, the second magnetic pole is located between the first magnetic pole and the head structure segment, and the fourth magnetic pole is located between the third magnetic pole and the head structure segment. The first and fourth magnetic poles are homonymous, and the first and third magnetic poles are heteronymous. The second and third magnetic poles are homonymous, and the second and fourth magnetic poles are heteronymous. When the sliding cover assembly is in the closed position, along the radial direction of the pen body assembly, the third magnetic pole is at least partially opposite to the first magnetic pole, and the fourth magnetic pole is at least partially opposite to the second magnetic pole.

[0027] This design facilitates the generation of magnetic forces along the axial direction and radial direction of the pen body assembly between the first sliding cover magnet and the pen body magnet when the sliding cover assembly is in the closed position, thereby ensuring that the closing contact portion presses against the grounding portion. Furthermore, it also facilitates the generation of a magnetic force along the axial direction of the pen body assembly during the sliding process, enabling automatic opening and closing after the sliding cover assembly slides to a preset position.

[0028] In one possible implementation, when the sliding cover assembly is in the closed position, the neutral surface of the pen body magnet is located between the neutral surface of the first sliding cover magnet and the head structure segment.

[0029] This facilitates the generation of magnetic forces along the axial direction and radial direction of the pen body assembly by the first sliding cover magnet and the pen body magnet when the sliding cover assembly is in the closed position, so as to press the closed contact part against the grounding part.

[0030] In one possible implementation, along the axial direction of the pen body assembly, the size of the first sliding magnet is larger than the size of the pen body magnet. When the sliding assembly is in the closed position, the pen body magnet is located between the two ends of the first sliding magnet, and the distance between the end of the first magnetic pole away from the second magnetic pole and the end of the third magnetic pole away from the fourth magnetic pole is greater than the distance between the end of the second magnetic pole away from the first magnetic pole and the end of the fourth magnetic pole away from the third magnetic pole.

[0031] This allows the first sliding cover magnet and the pen body magnet to generate magnetic forces along the axial direction and radial direction of the pen body assembly when the sliding cover assembly is in the closed position, so that the closed contact part can be pressed against the grounding part.

[0032] In one possible implementation, along the radial direction of the pen body assembly, at least a portion of the second closed contact portion of the closed contact part is opposite to the second magnetic pole, and at least a portion of the second grounding portion of the grounding part is opposite to the fourth magnetic pole.

[0033] This allows the second closing contact portion to deform toward the second grounding portion when the sliding cover assembly is in the closed position, so that the second closing contact portion can be pressed against the second grounding portion.

[0034] In one possible implementation, when the sliding cover assembly is in the open position, the first sliding cover magnet is located on the side of the third magnetic pole away from the head structure segment.

[0035] This allows for automatic opening and closing after the sliding cover assembly slides to a preset position.

[0036] In one possible implementation, the electrical connection portion further includes an opening contact portion. When the sliding cover assembly is in the open position, the opening contact portion is pressed against the grounding portion, and the opening contact portion and the grounding portion are in electrical contact.

[0037] This facilitates grounding of the metal structure when the sliding cover assembly is in the open position. Even with strong electrical interference at the stylus location, the metal structure is less prone to tripping when the sliding cover assembly is open, thus reducing the stylus's failure rate while ensuring high strength and a long lifespan for the sliding cover assembly.

[0038] In one possible implementation, the opening contact portion includes a first opening contact sub-portion, and the grounding portion includes a third grounding sub-portion. The third grounding sub-portion and the first opening contact sub-portion are arranged along the axial direction of the pen body assembly, with the first opening contact sub-portion located between the third grounding sub-portion and the head structure segment. Along the axial direction of the pen body assembly, the projection of the third grounding sub-portion and the projection of the first opening contact sub-portion at least partially coincide. When the sliding cover assembly is in the open position, the first opening contact sub-portion is pressed against the third grounding sub-portion along the axial direction of the pen body assembly, and the first opening contact sub-portion and the third grounding sub-portion are in electrical contact.

[0039] In this way, compared to frictional contact, the electrical contact when the first opening contact is pressed against the third grounding contact along the axial direction of the pen body assembly is more stable and reliable, making the grounding of the metal structural component more stable and reliable. Furthermore, the structure that grounds the metal structural component when the sliding cover assembly is in the open position has less impact on the relative sliding between the sliding cover assembly and the tail section, allowing for smooth opening and closing of the sliding cover assembly while simultaneously grounding it in the open position. Additionally, the wear caused by the relative sliding between the sliding cover assembly and the tail section has less impact on the service life and contact effect of the first opening contact and the third grounding contact, resulting in a longer service life and stable, reliable electrical contact. Moreover, when the sliding cover assembly is in the open position, the third grounding contact acts as a limiting structure, and the first opening contact acts as a mating structure. The contact between the first opening contact and the third grounding contact restricts the sliding cover assembly from moving away from the head section, making it less likely to slip off the pen body assembly and less likely to be lost.

[0040] In one possible implementation, the first opening contact is fixedly connected to the sliding structure of the metal structural member. Along the circumference of the pen body assembly, the first opening contact protrudes from the sliding structure, and the third grounding contact is located to the side of the sliding structure.

[0041] In this way, the first contact part is easy to set up, and the structure of the stylus is relatively simple.

[0042] In one possible implementation, the first opening contact is located in the groove of the tail structure section, and the third grounding contact is located on the groove wall.

[0043] This facilitates the smooth sliding of the sliding cover assembly via the sliding groove while simultaneously achieving the crimping of the first opening contact and the third grounding contact.

[0044] In one possible implementation, the metal structural component also includes a second sliding cover magnet. The second sliding cover magnet and the first sliding cover magnet are arranged axially spaced apart along the pen body assembly. When the sliding cover assembly is in the open position, the opening contact portion is pressed against the grounding portion under the magnetic force generated by the second sliding cover magnet and the pen body magnet.

[0045] This facilitates stable and reliable electrical contact between the opening contact and the grounding part when the sliding cover assembly is in the open position, and stable and reliable electrical contact between the closing contact and the grounding part when the sliding cover assembly is in the closed position. Consequently, the metal structural components can be stably and reliably grounded when the sliding cover assembly is in both the closed and open positions.

[0046] In one possible implementation, the opening contact portion includes a second opening contact sub-portion. The second opening contact sub-portion is located on the inner side of the sliding structure of the metal structural member. When the sliding cover assembly is in the open position, at least a portion of the second opening contact sub-portion is opposite to the second grounding sub-portion of the grounding portion along the radial direction of the pen body assembly. At least one of the second opening contact portion and the second grounding portion undergoes elastic deformation under the action of the magnetic force generated by the second sliding cover magnet and the pen body magnet, so that the second opening contact sub-portion is pressed against the second grounding sub-portion, and the second opening contact portion and the second grounding sub-portion make electrical contact.

[0047] In this way, when the sliding cover assembly is in the open position, stable and reliable grounding of the metal structural component can be achieved through the electrical contact between the second opening contact and the second grounding contact. Furthermore, the structure that grounds the metal structural component when the sliding cover assembly is in the open position has minimal impact on the relative sliding of the sliding cover assembly and the tail section, allowing for smooth opening and closing of the sliding cover assembly while simultaneously grounding the metal structural component in the open position.

[0048] In one possible implementation, the second sliding magnet is located between the first sliding magnet and the head structure segment. Along the radial direction of the pen body assembly, the pen body magnet is located inside the first and second sliding magnets. The pen body magnet has a third and a fourth magnetic pole, arranged axially along the pen body assembly, with the fourth magnetic pole located between the third magnetic pole and the head structure segment. The second sliding magnet has a fifth and a sixth magnetic pole, arranged axially along the pen body assembly, with the sixth magnetic pole located between the fifth magnetic pole and the head structure segment. The fourth and sixth magnetic poles are of the same name, and the fourth and fifth magnetic poles are of opposite names. The third and fifth magnetic poles are of the same name, and the fourth and sixth magnetic poles are of opposite names. When the sliding assembly is in the open position, the pen body magnet is located on the side of the sixth magnetic pole away from the head structure segment, and along the radial direction of the pen body assembly, the fifth and fourth magnetic poles are at least partially opposite each other.

[0049] In this way, the second sliding magnet and the pen body magnet can generate magnetic forces along the axial direction and radial direction of the pen body assembly. This facilitates the use of the magnetic forces generated by the second sliding magnet and the pen body magnet to drive the sliding assembly to slide along the axial direction of the pen body assembly, thereby achieving automatic opening and closing after the sliding assembly slides to a preset position. It also facilitates the use of the magnetic forces generated by the second sliding magnet and the pen body magnet to press the opening contact and the grounding part together in at least one direction of the axial and radial directions of the pen body assembly. When the sliding assembly is in the closed position, the magnetic force generated by the first sliding magnet and the pen body magnet allows the first closing contact to press against the first grounding part. When the sliding assembly is in the open position, the magnetic force generated by the second sliding magnet and the pen body magnet allows the first opening contact to press against the third grounding part.

[0050] In one possible implementation, when the sliding cover assembly is in the open position, the second sliding cover magnet is located on the side of the third magnetic pole near the head structure segment, and the fifth magnetic pole is partially opposite to the fourth magnetic pole along the radial direction of the pen body assembly.

[0051] This allows the second sliding cover magnet and the pen body magnet to generate magnetic forces along the axial direction and radial direction of the pen body assembly when the sliding cover assembly is in the open position, so that the opening contact part can be pressed against the grounding part.

[0052] In one possible implementation, the stylus also includes a flexible conductive element. One end of the flexible conductive element is connected to a grounding portion, and the other end is connected to an electrical connection portion, which is electrically connected to the grounding portion via the flexible conductive element.

[0053] In this way, the metal structural components can be stably and reliably grounded during the sliding process of the sliding cover assembly. This makes it less likely for the metal structural components to trip even if there is strong electrical interference at the stylus when the sliding cover assembly is in the open position, closed position, and between the open and closed positions. This helps to reduce the failure rate of the stylus while ensuring that the sliding cover assembly of the stylus has high strength and long service life.

[0054] In one possible implementation, the electrical connection is located on the outer side of the metal structural member.

[0055] This design allows for a larger connection surface between the electrical connection part and the flexible conductive element, facilitating a stable and reliable electrical connection. Furthermore, the flexible conductive element has minimal impact on the sliding of the cover assembly. Additionally, when the cover assembly is in the closed position, the redundant portion of the flexible conductive element can be accommodated on the side of the metal structure away from the head structure section, facilitating the containment of the flexible conductive element.

[0056] In one possible implementation, the grounding part is located on the inner side of the tail structure segment, and the end of the tail structure segment away from the head structure segment is an open structure, with the flexible conductive element passing through the open structure at the end of the tail structure segment away from the head structure segment.

[0057] This design allows for a larger connection surface between the grounding part and the flexible conductive element, facilitating a stable and reliable electrical connection between them. Furthermore, the flexible conductive element has minimal impact on the sliding of the cover assembly.

[0058] In one possible implementation, a conductive elastic element is provided between the metal structural component and the tail section. The conductive elastic element is fixed and electrically connected to one of the electrical connection portion and the grounding portion. When the sliding cover assembly is in the closed position, the conductive elastic element is pressed against the other of the electrical connection portion and the grounding portion, and is in electrical contact with the other of the electrical connection portion and the grounding portion.

[0059] In this way, by using conductive elastic components, the metal structural components can be grounded when the sliding cover is in the closed position, while minimizing the impact on the sliding of the cover assembly. This makes it less likely for the metal structural components to trip even if there is strong electrical interference at the stylus. This helps to reduce the failure rate of the stylus while ensuring that the sliding cover assembly of the stylus has high strength and a long service life.

[0091] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0092] Figure 1 This is a schematic diagram of an electronic device component provided in an embodiment of this application.

[0093] like Figure 1 As shown, this application embodiment provides an electronic device component, which includes an electronic device 2 and a stylus 1. The stylus 1 can also be called a touch pen or electronic pen. The stylus 1 can be used as an input device to interact with the electronic device 2. The stylus 1 and the electronic device 2 work together to facilitate accurate drawing, writing, touch and other operations.

[0094] For example, electronic device 2 may include, but is not limited to, mobile phones, portable Android devices (PADs), handwriting tablets, laptops, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices, in-vehicle devices, wearable devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes, etc. This application embodiment uses a tablet computer as an example for illustration.

[0095] For example, electronic device 2 may include a display screen, and stylus 1 can interact with electronic device 2 by performing operations such as writing, drawing, and pressing on the display screen.

[0096] Figure 2 This is a schematic diagram of a stylus sliding cover assembly in the closed position, provided as an embodiment of this application. Figure 3 for Figure 2 The provided diagram shows the sliding cover assembly of the stylus in the open position. In the accompanying drawings of this application, direction a represents the axial direction of the pen body assembly 100, direction b represents the circumferential direction of the pen body assembly 100, and direction c represents the radial direction of the pen body assembly 100.

[0097] like Figure 2 , Figure 3 As shown, the stylus 1 includes a pen body assembly 100, which can be used by a user to hold. The pen body assembly 100 includes a head structure segment 121 and a tail structure segment 111, which are located at opposite ends of the axial direction of the pen body assembly 100. The head structure segment 121 is provided with a pen tip, which can be used for writing, drawing, touch operations, etc. The tail structure segment 111 may have one or more electronic devices.

[0098] For example, any electronic device may include, but is not limited to, a charging interface 300, a communication device, a control device, etc. This embodiment of the application uses the tail structure segment 111 having a charging interface 300 as an example for illustration. When the tail structure segment 111 has a charging interface 300, the stylus 1 can be charged through the charging interface 300.

[0099] For example, the charging port 300 can be a Type-C port.

[0100] In some examples, the pen body assembly 100 includes a housing 120 and a metal bracket 110. The housing 120 may be made of an insulating material such as plastic, and the metal bracket 110 is disposed within the housing 120. The housing 120 includes a head structure segment 121, and the metal bracket 110 includes a connecting segment 112 and a tail structure segment 111. The connecting segment 112 is located inside the housing 120, and the tail structure segment 111 is located on the outside of the housing 120 on the side away from the head structure segment 121. The metal bracket 110 is fixedly connected to the housing 120 via the connecting segment 112.

[0101] For example, the connecting segment 112 can be adhered to the inner side of the housing 120.

[0102] In the embodiments of this application, the inner surface of a component or structure refers to the surface of the object being described that is radially close to the axis of the pen body assembly 100, and the outer surface of a component or structure refers to the surface of the object being described that is radially away from the axis of the pen body assembly 100.

[0103] For example, the outer surface of the tail structure segment 111 may include an arc-shaped surface and a flat surface arranged circumferentially along the pen body assembly 100, and the charging interface 300 may be provided on the flat surface.

[0104] like Figure 2 , Figure 3As shown, the stylus 1 also includes a sliding cover assembly 200. The sliding cover assembly 200 is located on the outside of the tail structure section 111. The sliding cover assembly 200 is slidably disposed on the tail structure section 111. The sliding cover assembly 200 can slide along the axis of the pen body assembly 100 between an open position away from the head structure section 121 and a closed position close to the head structure section 121, so that the sliding cover assembly 200 slides more smoothly. In addition, the sliding cover assembly 200 can also have a longer stroke.

[0105] When the sliding cover assembly 200 is in the closed position, the electronic components on the tail section 111 are located inside the sliding cover assembly 200. The sliding cover assembly 200 can shield the electronic components on the tail section 111, which is beneficial for the protection of the electronic components on the tail section 111 and for the aesthetic appearance of the stylus 1. When the sliding cover assembly 200 is in the open position, the electronic components on the tail section 111 can be exposed, which is convenient for use and maintenance of the electronic components on the tail section 111. For example, in the example where the tail section 111 has a charging port 300, when the sliding cover assembly 200 is in the closed position, the sliding cover assembly 200 can prevent dust, water, etc. from entering the charging port 300, which is beneficial for protecting the charging port 300. When the sliding cover assembly 200 is in the open position, it is convenient to connect the charging port 300 to the charging cable and to maintain the charging port 300.

[0106] In some examples, the sliding cover assembly 200 may surround a portion of the tail structure segment 111 circumferentially around the pen body assembly 100.

[0107] In some examples, the sliding cover assembly 200 can be fitted onto the outside of the tail structure segment 111. In this case, the sliding cover assembly 200 surrounds the tail structure segment 111 circumferentially around the pen body assembly 100. The sliding cover assembly 200 can also be called a pen cap assembly. This application embodiment uses the example of the sliding cover assembly 200 being fitted onto the outside of the tail structure segment 111 for illustration.

[0108] For example, the end of the sliding cover assembly 200 away from the head structure segment 121 is a sealed structure, and along the axial direction of the pen body assembly 100, the projection of the sliding cover assembly 200 covers the projection of the tail structure segment 111.

[0109] Figure 4 This is a partial perspective view of a stylus sliding cover assembly in the closed position, provided as an embodiment of this application. Figure 5 for Figure 4 A partial perspective view of the stylus's sliding cover assembly in the open position.

[0110] like Figure 4 , Figure 5As shown, the sliding cover assembly 200 includes a metal structural member 210 and an outer cover 220. The metal structural member 210 is fixedly disposed on the inner wall of the outer cover 220. The sliding cover assembly 200 is slidably disposed on the tail structure section 111 via the metal structural member 210. By providing the metal structural member 210 and allowing the sliding cover assembly 200 to be slidably disposed on the tail structure section 111 via the metal structural member 210, the sliding cover assembly 200 can have high strength and a long service life.

[0111] For example, the outer cover 220 can be fitted onto the outside of the tail structure segment 111. In this case, the outer cover 220 surrounds the tail structure segment 111 around the circumference of the pen body assembly 100. The outer cover 220 can also be called a pen cap.

[0112] For example, the outer cover 220 may be made of an insulating material such as plastic.

[0113] For example, the metal structural member 210 can be bonded to the inner wall of the outer cover 220 via the adhesive structure 230.

[0114] For example, the metal structural member 210 includes a sliding structure 211, which is slidably disposed on the tail structural section 111.

[0115] For example, the sliding structure 211 extends along the axial direction of the pen body assembly 100.

[0116] For example, the sliding structure 211 may include, but is not limited to, a slide rail, a sliding rod, etc.

[0117] In some examples, the metal structure 210 may include a plurality of sliding structures 211 spaced circumferentially along the pen body assembly 100 to improve the stability of the sliding of the metal structure 210. For example, the metal structure 210 may include two sliding structures 211, which may be arranged radially opposite to each other along the pen body assembly 100.

[0118] In some examples, the metal structural component 210 also includes a connecting structure 212 located on the side of the tail structural segment 111 away from the head structural segment 121. The end of the sliding structure 211 away from the head structural segment 121 is connected through the connecting structure 212, making the structure of the metal structural component 210 more stable and helping to improve the strength of the sliding cover assembly 200.

[0119] For example, the connection structure 212 may include, but is not limited to, a connection ring, a connection plate, a connection frame, etc.

[0120] In related technologies, a certain gap is often maintained between the metal structural component and the tail section to ensure smooth sliding. When there is strong electrical interference at the stylus, a short circuit can easily occur at the metal structural component, potentially leading to stylus malfunctions. For example, when electrostatic discharge (ESD) occurs at the stylus due to friction, a secondary short circuit can easily occur at the metal structural component, again causing stylus malfunctions.

[0121] like Figure 4 , Figure 5 As shown, based on this, in this embodiment of the application, the tail structure segment 111 has a grounding portion 400, and the metal structure 210 has an electrical connection portion 500. When the sliding cover assembly 200 is in the closed position, the metal structure 210 is electrically connected to the grounding portion 400 through the electrical connection portion 500.

[0122] In this way, after the metal structural component 210 is electrically connected to the grounding part 400 through the electrical connection part 500, it can be grounded. This makes it less likely for the metal structural component 210 to trip when the sliding cover assembly 200 is in the closed position, even if there is strong electrical interference at the stylus 1 (for example, an electrostatic discharge event occurs). This helps to reduce the failure rate of the stylus 1 while ensuring that the sliding cover assembly 200 of the stylus 1 has high strength and long service life.

[0123] In some examples where the metal structural member 210 includes multiple sliding structures 211, one or more sliding structures 211 are provided with an electrical connection portion 500, and the tail structural section 111 has a grounding portion 400 corresponding to the electrical connection portion 500, and the electrical connection portion 500 is electrically connected to the corresponding grounding portion 400. For example, each sliding structure 211 is provided with an electrical connection portion 500.

[0124] In some examples, the sliding cover assembly 200 can be removed from the pen body assembly 100 by sliding the sliding cover assembly 200 away from the head structure segment 121.

[0125] In some examples, the tail section 111 is provided with a limiting structure, and the metal structural member 210 is provided with a mating structure. Specifically, the mating structure can be fixedly connected to the sliding structure 211. The limiting structure and the mating structure are arranged along the axial direction of the pen body assembly 100, and the projections of the limiting structure and the mating structure at least partially overlap along the axial direction of the pen body assembly 100. When the sliding cover assembly 200 is in the open position, the limiting structure and the mating structure abut against each other to restrict the sliding cover assembly 200 from moving away from the head section 121, making it difficult for the sliding cover assembly 200 to slip off the pen body assembly 100 and difficult to lose.

[0126] For example, when the sliding cover assembly 200 is in the open position, the metal structure 210 is electrically connected to the grounding portion 400 via the electrical connection portion 500.

[0127] In this way, even if there is strong electrical interference at the stylus 1 when the sliding cover assembly 200 is in the open position, the metal structure 210 is not prone to power outages. This helps to reduce the failure rate of the stylus 1 while ensuring that the sliding cover assembly 200 of the stylus 1 has high strength and a long service life.

[0128] In some possible implementations, the electrical connection portion 500 includes a closing contact portion 510, which is pressed against the grounding portion 400 when the sliding cover assembly 200 is in the closed position, thus making electrical contact between the closing contact portion 510 and the grounding portion 400. This facilitates grounding of the metal structural member 210 when the sliding cover assembly 200 is in the closed position.

[0129] In some possible implementations, the electrical connection portion 500 further includes an opening contact portion 520, which, when the sliding cover assembly 200 is in the open position, presses against the grounding portion 400, thus making electrical contact between the opening contact portion 520 and the grounding portion 400. This facilitates grounding of the metal structural member 210 when the sliding cover assembly 200 is in the open position.

[0130] For example, the closing contact portion 510 and the opening contact portion 520 are arranged axially spaced along the pen body assembly 100 so that the closing contact portion 510 is pressed against the ground portion 400 when the sliding cover assembly 200 is in the closed position, and the opening contact portion 520 is pressed against the ground portion 400 when the sliding cover assembly 200 is in the open position.

[0131] In some possible implementations, the metal structural member 210 is provided with a first sliding cover magnet 610, and the tail structural section 111 is provided with a pen body magnet 620. When the sliding cover assembly 200 is in the closed position, the closing contact portion 510 is pressed against the grounding portion 400 under the action of the magnetic force generated by the first sliding cover magnet 610 and the pen body magnet 620.

[0132] In this way, when the sliding cover assembly 200 is in the closed position, the closing contact part 510 and the grounding part 400 make stable and reliable electrical contact, which makes the metal structural component 210 grounded stably and reliably, which helps to reduce the failure rate of the stylus 1.

[0133] In some possible implementations, the closing contact portion 510 includes a first closing contact sub-portion 511, and the grounding portion 400 includes a first ground sub-portion 410. The first ground sub-portion 410 and the first closing contact sub-portion 511 are arranged along the axial direction of the pen body assembly 100, with the first ground sub-portion 410 located between the first closing contact sub-portion 511 and the head structure segment 121. Along the axial direction of the pen body assembly 100, the projection of the first ground sub-portion 410 at least partially coincides with the projection of the first closing contact sub-portion 511. When the sliding cover assembly 200 is in the closed position, the first closing contact sub-portion 511 is pressed against the first ground sub-portion 410 along the axial direction of the pen body assembly 100, and the first closing contact sub-portion 511 and the first ground sub-portion 410 are in electrical contact.

[0134] In this way, compared to frictional contact, the electrical contact when the first closed contact portion 511 is pressed against the first grounding portion 410 along the axial direction of the pen body assembly 100 is more stable and reliable, making the grounding of the metal structural component 210 more stable and reliable. Furthermore, the structure that grounds the metal structural component 210 when the sliding cover assembly 200 is in the closed position has less impact on the relative sliding between the sliding cover assembly 200 and the tail structural section 111, allowing for smooth opening and closing of the sliding cover assembly 200 while simultaneously grounding the metal structural component 210 when it is in the closed position. Additionally, the wear caused by the relative sliding between the sliding cover assembly 200 and the tail structural section 111 has less impact on the service life and contact effect of the first closed contact portion 511 and the first grounding portion 410, resulting in a longer service life and more stable and reliable electrical contact.

[0135] For example, when the sliding cover assembly 200 is in the closed position, the first closing contact portion 511 is pressed against the first grounding portion 410 along the axial direction of the pen body assembly 100 under the action of the magnetic force generated by the first sliding cover magnet 610 and the pen body magnet 620, so that the electrical contact between the first closing contact portion 511 and the first grounding portion 410 is stable and reliable, and the grounding of the metal structure 210 is stable and reliable.

[0136] In some possible implementations, the first grounding part 410 is located at one end of the tail structure segment 111 away from the head structure segment 121, and the first closing contact part 511 is located on the side of the tail structure segment 111 away from the head structure segment 121.

[0137] This allows the first closing contact portion 511 to press against the first grounding portion 410 when the sliding cover assembly 200 is in the closed position. Furthermore, the placement of the first closing contact portion 511 against the first grounding portion 410 has minimal impact on the overall structure of the stylus 1, facilitating smooth opening and closing of the sliding cover assembly 200. Additionally, it also allows the sliding cover assembly 200 to have a longer sliding stroke.

[0138] For example, the end of the tail structure segment 111 away from the head structure segment 121 forms a first grounding part 410, making the formation of the first grounding part 410 simpler and more convenient.

[0139] For example, the first closed contact portion 511 may be located at one end of the metal structure 210 away from the head structure segment 121.

[0140] In some possible implementations, the first closed contact portion 511 is fixedly connected to the sliding structure 211, and the first closed contact portion 511 protrudes from the inner side of the sliding structure 211.

[0141] In this way, the first closed contact portion 511 is more conveniently designed, making it easier for the first closed contact portion 511 to press against the first grounding portion 410 located at the end of the tail structure segment 111 away from the head structure segment 121. In addition, the first closed contact portion 511 has less impact on the sliding of the metal structure component 210.

[0142] For example, the first closed contact portion 511 may be located in the connection structure 212.

[0143] For example, at least a portion of the connection structure 212 forms a first closed contact portion 511, making the formation of the first closed contact portion 511 relatively simple and convenient.

[0144] In other examples, the first grounding part 410 may also be provided on the side of the sliding structure 211 in the circumferential direction of the pen body assembly 100, and the first closing contact part 511 protrudes from the sliding structure 211 in the circumferential direction of the pen body assembly 100.

[0145] Figure 6 This application provides a cross-sectional schematic diagram of a stylus at the magnet on the pen body, which is an embodiment of the present application.

[0146] like Figure 6 As shown, in some possible embodiments, the tail section 111 has a groove G1 extending axially along the pen body assembly 100 and passing through the end of the tail section 111 away from the head section 121. A sliding structure 211 is disposed within the groove G1, and the sliding structure 211 slidably engages with the groove G1. The metal structural member 210 is slidably disposed on the tail section 111 via the sliding structure 211 and the groove G1. The groove G1 guides the sliding structure 211 to slide axially along the pen body assembly 100, making the opening and closing of the cover assembly 200 smoother. Furthermore, the groove G1 and the sliding structure 211 can restrict the rotation of the cover assembly 200, facilitating a stable and reliable electrical connection between the grounding portion 400 and the electrical connection portion 500 when the cover assembly 200 is in the open or closed position.

[0147] For example, the groove G1 is located on the outer side of the tail structure segment 111.

[0148] In some possible implementations, the first closed contact portion 511 is located on the side of the slide G1 away from the head structure segment 121.

[0149] This facilitates the smooth sliding of the sliding cover assembly 200 via the slide groove G1 while simultaneously achieving the pressing connection between the first closing contact portion 511 and the first grounding portion 410. The first closing contact portion 511 is less likely to affect the sliding of the sliding structure 211 within the slide groove G1. While it is convenient for the first closing contact portion 511 to press the first grounding portion 410 located at the end of the tail structure segment 111 away from the head structure segment 121, the opening and closing of the sliding cover assembly 200 is smoother, and the sliding cover assembly 200 is less likely to rotate relative to the tail structure segment 111.

[0150] like Figure 4 , Figure 5 As shown, in some possible embodiments, the inner side of the sliding structure 211 has a first groove G2, and the first sliding cover magnet 610 is fixedly disposed in the first groove G2.

[0151] In this way, the distance between the first sliding cover magnet 610 and the pen body magnet 620 is small, and the magnetic force generated is large. At the same time, the setting of the first sliding cover magnet 610 is not likely to affect the sliding of the sliding structure 211 relative to the tail structure segment 111.

[0152] For example, the first sliding cover magnet 610 is located on the outside of the tail structure segment 111.

[0153] In some possible embodiments, the first sliding magnet 610 has a first magnetic pole 611 and a second magnetic pole 612, which are arranged along the axial direction of the pen body assembly 100. The pen body magnet 620 has a third magnetic pole 621 and a fourth magnetic pole 622, which are also arranged along the axial direction of the pen body assembly 100. The pen body magnet 620 is located inside the first sliding magnet 610 along the radial direction of the pen body assembly 100.

[0154] In this way, the first sliding cover magnet 610 and the pen body magnet 620 can generate magnetic forces along the axial direction and radial direction of the pen body assembly 100. This facilitates the use of the magnetic forces generated by the first sliding cover magnet 610 and the pen body magnet 620 to drive the sliding cover assembly 200 to slide along the axial direction of the pen body assembly 100, thereby achieving automatic opening and closing after the sliding cover assembly 200 slides to a preset position. It also facilitates the use of the magnetic forces generated by the first sliding cover magnet 610 and the pen body magnet 620 to achieve the pressing of the electrical connection part 500 and the grounding part 400 in at least one direction of the axial direction and the radial direction of the pen body assembly 100.

[0155] like Figure 6 As shown, in some possible embodiments, the tail section 111 has a magnet mounting cavity C, and the pen body magnet 620 is fixedly disposed in the magnet mounting cavity C.

[0156] This makes the placement of the pen body magnet 620 more convenient. Furthermore, the placement of the pen body magnet 620 does not easily obstruct the relative sliding of the sliding cover assembly 200 and the tail structure section 111.

[0157] like Figure 4 , Figure 5 As shown, in some possible embodiments, the second magnetic pole 612 is located between the first magnetic pole 611 and the head structure segment 121, and the fourth magnetic pole 622 is located between the third magnetic pole 621 and the head structure segment 121. The first magnetic pole 611 and the fourth magnetic pole 622 are the same magnetic poles, and the first magnetic pole 611 and the third magnetic pole 621 are opposite magnetic poles. The second magnetic pole 612 and the third magnetic pole 621 are the same magnetic poles, and the second magnetic pole 612 and the fourth magnetic pole 622 are opposite magnetic poles. When the sliding cover assembly 200 is in the closed position, along the radial direction of the pen body assembly 100, the third magnetic pole 621 is at least partially opposite to the first magnetic pole 611, and the fourth magnetic pole 622 is at least partially opposite to the second magnetic pole 612.

[0158] This facilitates the generation of magnetic forces along the axial direction and radial direction of the pen body assembly 100 by the first sliding cover magnet 610 and the pen body magnet 620 when the sliding cover assembly 200 is in the closed position, so as to press the closing contact portion 510 against the grounding portion 400. Furthermore, it also facilitates the generation of magnetic forces along the axial direction of the pen body assembly 100 during the sliding of the sliding cover assembly 200, so as to achieve automatic opening and closing after the sliding cover assembly 200 slides to a preset position.

[0159] For example, both the first sliding cover magnet 610 and the pen body magnet 620 can be bar magnets.

[0160] For example, the first magnetic pole 611 and the fourth magnetic pole 622 can be S poles, and the second magnetic pole 612 and the third magnetic pole 621 can be N poles.

[0161] like Figure 4 As shown, in some possible implementations, when the sliding cover assembly 200 is in the closed position, the neutral surface of the pen body magnet 620 is located between the neutral surface of the first sliding cover magnet 610 and the head structure segment 121.

[0162] This facilitates the generation of magnetic forces along the axial direction and radial direction of the pen body assembly 100 by the first sliding cover magnet 610 and the pen body magnet 620 when the sliding cover assembly 200 is in the closed position, so as to press the closed contact portion 510 against the grounding portion 400.

[0163] For example, the neutral plane of a magnet refers to the virtual plane separating the two magnetic poles of the magnet; the neutral plane of a magnet can also be called the equatorial plane of the magnet. The first magnetic pole 611 and the second magnetic pole 612 are located on both sides of the neutral plane of the first sliding magnet 610. The third magnetic pole 621 and the fourth magnetic pole 622 are located on both sides of the neutral plane of the pen body magnet 620.

[0164] For example, when the sliding cover assembly 200 is in the closed position, the magnetic attraction force generated between the first magnetic pole 611 and the third magnetic pole 621 along the axial direction of the pen body assembly 100 can press the first closing contact portion 511 into the first grounding portion 410.

[0165] In some possible implementations, along the axial direction of the pen body assembly 100, the size of the first sliding cover magnet 610 is larger than the size of the pen body magnet 620. When the sliding cover assembly 200 is in the closed position, the pen body magnet 620 is located between the two ends of the first sliding cover magnet 610. The distance between the end of the first magnetic pole 611 away from the second magnetic pole 612 and the end of the third magnetic pole 621 away from the fourth magnetic pole 622 is greater than the distance between the end of the second magnetic pole 612 away from the first magnetic pole 611 and the end of the fourth magnetic pole 622 away from the third magnetic pole 621.

[0166] This facilitates the generation of magnetic forces along the axial direction and radial direction of the pen body assembly 100 by the first sliding cover magnet 610 and the pen body magnet 620 when the sliding cover assembly 200 is in the closed position, so as to press the closed contact portion 510 against the grounding portion 400.

[0167] like Figure 5 As shown, in some possible implementations, when the sliding cover assembly 200 is in the open position, the first sliding cover magnet 610 is located on the side of the third magnetic pole 621 away from the head structure segment 121.

[0168] This facilitates automatic opening and closing after the sliding cover assembly 200 is slid to the preset position.

[0169] It is understandable that the relative positions of the first sliding cover magnet 610 and the pen body magnet 620, as well as the polarity of the magnetic poles, can also be adjusted, as long as the magnetic force is generated when the sliding cover assembly 200 is in the closed position, causing the closed contact 510 to press against the grounding part 400.

[0170] like Figure 4 , Figure 5As shown, in some possible embodiments, the opening contact portion 520 includes a first opening contact sub-portion 521, and the grounding portion 400 includes a third grounding sub-portion 430. The third grounding sub-portion 430 and the first opening contact sub-portion 521 are arranged along the axial direction of the pen body assembly 100, with the first opening contact sub-portion 521 located between the third grounding sub-portion 430 and the head structure segment 121. Along the axial direction of the pen body assembly 100, the projection of the third grounding sub-portion 430 at least partially overlaps with the projection of the first opening contact sub-portion 521. When the sliding cover assembly 200 is in the open position, the first opening contact sub-portion 521 is pressed against the third grounding sub-portion 430 along the axial direction of the pen body assembly 100, and the first opening contact sub-portion 521 and the third grounding sub-portion 430 are in electrical contact.

[0171] In this way, compared to frictional contact, the electrical contact when the first opening contact portion 521 is pressed against the third grounding portion 430 along the axial direction of the pen body assembly 100 is more stable and reliable, making the grounding of the metal structural component 210 more stable and reliable. Furthermore, the structure that grounds the metal structural component 210 when the sliding cover assembly 200 is in the open position has less impact on the relative sliding between the sliding cover assembly 200 and the tail section 111, allowing for smooth opening and closing of the sliding cover assembly 200 while grounding it in the open position. Additionally, the wear caused by the relative sliding between the sliding cover assembly 200 and the tail section 111 has less impact on the service life and contact effect of the first opening contact portion 521 and the third grounding portion 430, resulting in a longer service life and more stable and reliable electrical contact.

[0172] In addition, when the sliding cover assembly 200 is in the open position, the third grounding part 430 can act as a limiting structure, and the first opening contact part 521 can act as a cooperating structure. Through the contact between the first opening contact part 521 and the third grounding part 430, the sliding cover assembly 200 can be restricted from moving away from the head structure section 121, so that the sliding cover assembly 200 is not easy to slip off the pen body assembly 100 and the sliding cover assembly 200 is not easy to lose.

[0173] For example, the third grounding part 430 may be located in the limiting structure, and the first opening contact part 521 may be located in the mating structure.

[0174] For example, the third grounding part 430 can be integrated with the limiting structure, and the first opening contact part 521 can be integrated with the mating structure. That is, at least part of the limiting structure forms the third grounding part 430, and at least part of the mating structure forms the first opening contact part 521, making it easier to form the third grounding part 430 and the first opening contact part 521, and making the structure of the stylus 1 simpler.

[0175] For example, along the axial direction of the pen body assembly 100, the first opening contact portion 521 and the third grounding portion 430 are located on the side of the first grounding portion 410 near the head structure segment 121, so that the crimping of the first opening contact portion 521 and the third grounding portion 430 is not easily affected by the first grounding portion 410 and the first closing contact portion 511.

[0176] In some possible implementations, the first opening contact portion 521 is fixedly connected to the sliding structure 211, and the first opening contact portion 521 protrudes from the surface of the sliding structure 211.

[0177] In this way, the first opening contact 521 is set in a more convenient way, which makes it easier to press the first opening contact 521 and the third grounding contact 430 together when the sliding cover assembly 200 is in the open position.

[0178] In some examples, along the circumference of the pen body assembly 100, a first opening contact portion 521 protrudes from the sliding structure 211, and a third grounding portion 430 is located to the side of the sliding structure 211.

[0179] In this way, the setup of the first opening contact 521 and the third grounding contact 430 is relatively easy, and the structure of the stylus 1 is relatively simple.

[0180] In other examples, the first opening contact portion 521 may also protrude from the inner side of the sliding structure 211, the third grounding portion 430 is located on the inner side of the sliding structure 211 along the radial direction of the pen body assembly 100, and the tail structure segment 111 has a clearance groove for the first opening contact portion 521 to move.

[0181] In some possible implementations, the first opening contact portion 521 is located at one end of the sliding structure 211 near the head structure segment 121, so as to give the sliding cover assembly 200 a longer sliding stroke.

[0182] In some possible implementations, the first opening contact portion 521 is disposed in the slide groove G1, and the third grounding portion 430 is located on the groove wall of the slide groove G1.

[0183] This facilitates the smooth sliding of the sliding cover assembly 200 via the slide groove G1, while simultaneously achieving the crimping of the first opening contact part 521 and the third grounding part 430.

[0184] In some possible implementations, when the sliding cover assembly 200 is in the open position, the first opening contact portion 521 can be pressed against the third grounding portion 430 along the axial direction of the pen body assembly 100 under the action of the magnetic force generated by the first sliding cover magnet 610 and the pen body magnet 620.

[0185] In this way, when the sliding stroke of the sliding cover assembly 200 is short, the electrical contact between the first opening contact part 521 and the third grounding part 430 can be stable and reliable, while the structure of the stylus 1 is relatively simple.

[0186] like Figure 4 , Figure 5 As shown, in some possible embodiments, the metal structural member 210 is further provided with a second sliding cover magnet 630. The second sliding cover magnet 630 and the first sliding cover magnet 610 are arranged axially spaced along the pen body assembly 100. When the sliding cover assembly 200 is in the open position, the opening contact portion 520 is pressed against the grounding portion 400 under the action of the magnetic force generated by the second sliding cover magnet 630 and the pen body magnet 620.

[0187] This facilitates stable and reliable electrical contact between the opening contact 520 and the grounding part 400 when the sliding cover assembly 200 is in the open position, and stable and reliable electrical contact between the closing contact 510 and the grounding part 400 when the sliding cover assembly 200 is in the closed position. Consequently, the metal structural component 210 can be stably and reliably grounded when the sliding cover assembly 200 is in both the closed and open positions.

[0188] For example, when the sliding cover assembly 200 is in the open position, the first opening contact portion 521 can be pressed against the third grounding portion 430 along the axial direction of the pen body assembly 100 under the action of the magnetic force generated by the second sliding cover magnet 630 and the pen body magnet 620, so as to achieve stable and reliable electrical contact between the first opening contact portion 521 and the third grounding portion 430 when the sliding stroke of the sliding cover assembly 200 is long.

[0189] In some examples, the inner side of the sliding structure 211 has a second groove G3, and the second sliding cover magnet 630 is fixedly disposed in the second groove G3.

[0190] In this way, the gap between the second sliding cover magnet 630 and the pen body magnet 620 is small, and the magnetic force generated is large. At the same time, the setting of the second sliding cover magnet 630 is not likely to affect the sliding of the sliding structure 211 relative to the tail structure segment 111.

[0191] For example, the second sliding cover magnet 630 is located on the outside of the tail structure section 111.

[0192] In some possible implementations, the second sliding magnet 630 is located between the first sliding magnet 610 and the head structure segment 121, and the pen body magnet 620 is located inside the first sliding magnet 610 and the second sliding magnet 630 along the radial direction of the pen body assembly 100.

[0193] This allows the first closing contact portion 511 to be pressed against the first grounding portion 410 by the magnetic force generated by the first sliding cover magnet 610 and the pen body magnet 620 when the sliding cover assembly 200 is in the closed position. When the sliding cover assembly 200 is in the open position, the first opening contact portion 521 is pressed against the third grounding portion 430 by the magnetic force generated by the second sliding cover magnet 630 and the pen body magnet 620.

[0194] In some examples, the pen body magnet 620 has a third magnetic pole 621 and a fourth magnetic pole 622, which are arranged along the axial direction of the pen body assembly 100. The second sliding cover magnet 630 has a fifth magnetic pole 631 and a sixth magnetic pole 632, which are arranged along the axial direction of the pen body assembly 100.

[0195] In this way, the second sliding cover magnet 630 and the pen body magnet 620 can generate magnetic forces along the axial direction and radial direction of the pen body assembly 100. This facilitates the use of the magnetic forces generated by the second sliding cover magnet 630 and the pen body magnet 620 to drive the sliding cover assembly 200 to slide along the axial direction of the pen body assembly 100, thereby achieving automatic opening and closing after the sliding cover assembly 200 slides to a preset position. It also facilitates the use of the magnetic forces generated by the second sliding cover magnet 630 and the pen body magnet 620 to achieve the pressing of the opening contact 520 and the grounding part 400 in at least one direction of the axial and radial directions of the pen body assembly 100.

[0196] In some examples, the fourth magnetic pole 622 is located between the third magnetic pole 621 and the head structure segment 121, and the sixth magnetic pole 632 is located between the fifth magnetic pole 631 and the head structure segment 121. The fourth magnetic pole 622 and the sixth magnetic pole 632 are homonymous magnetic poles, and the fourth magnetic pole 622 and the fifth magnetic pole 631 are heteronymous magnetic poles. The third magnetic pole 621 and the fifth magnetic pole 631 are homonymous magnetic poles, and the fourth magnetic pole 622 and the sixth magnetic pole 632 are heteronymous magnetic poles. When the sliding cover assembly 200 is in the open position, the pen body magnet 620 is located on the side of the sixth magnetic pole 632 away from the head structure segment 121, and along the radial direction of the pen body assembly 100, the fifth magnetic pole 631 and the fourth magnetic pole 622 are at least partially opposite each other.

[0197] This facilitates the generation of magnetic forces along the axial direction and radial direction of the pen body assembly 100 between the second sliding cover magnet 630 and the pen body magnet 620 when the sliding cover assembly 200 is in the open position, so as to press the opening contact 520 into the grounding part 400. Furthermore, it also facilitates the generation of magnetic forces along the axial direction of the pen body assembly 100 during the sliding of the sliding cover assembly 200, so as to achieve automatic opening and closing after the sliding cover assembly 200 slides to a preset position.

[0198] For example, the second magnetic pole 612 is located between the first magnetic pole 611 and the fifth magnetic pole 631.

[0199] For example, the second sliding cover magnet 630 can be a bar magnet.

[0200] For example, the first magnetic pole 611, the fourth magnetic pole 622 and the sixth magnetic pole 632 can be S poles, and the second magnetic pole 612, the third magnetic pole 621 and the fifth magnetic pole 631 can be N poles.

[0201] In some possible implementations, when the sliding cover assembly 200 is in the open position, the second sliding cover magnet 630 is located on the side of the third magnetic pole 621 near the head structure segment 121, and the fifth magnetic pole 631 is partially opposite to the fourth magnetic pole 622 along the radial direction of the pen body assembly 100.

[0202] This facilitates the second sliding cover magnet 630 and the pen body magnet 620 to generate magnetic forces along the axial direction of the pen body assembly 100 and along the radial direction of the pen body assembly 100 when the sliding cover assembly 200 is in the open position, so as to press the opening contact portion 520 into the grounding portion 400.

[0203] For example, when the sliding cover assembly 200 is in the open position, the magnetic attraction force generated between the fourth magnetic pole 622 and the fifth magnetic pole 631 along the axial direction of the pen body assembly 100 can press the first opening contact portion 521 into the third grounding portion 430.

[0204] For example, when the sliding cover assembly 200 is in the closed position, the pen body magnet 620 is located on the side of the second sliding cover magnet 630 away from the head structure segment 121. This facilitates automatic opening and closing after the sliding cover assembly 200 slides to a preset position.

[0205] Understandably, the relative positions of the first sliding cover magnet 610, the second sliding cover magnet 620, and the pen body magnet 620, as well as the polarity of the magnetic poles, can also be adjusted, as long as the magnetic force that causes the closing contact 510 to press against the grounding part 400 is generated when the sliding cover assembly 200 is in the closed position, and the magnetic force that causes the opening contact 520 to press against the grounding part 400 is generated when the sliding cover assembly 200 is in the open position.

[0206] Figure 7 A partial perspective view of the sliding cover assembly of another stylus provided in this application embodiment when it is in the closed position. Figure 8 for Figure 7 The provided image shows a partial perspective view of the stylus's sliding cover assembly in the open position. Figure 9 This application provides another schematic cross-sectional view of the stylus at the magnet on the pen body, which is an embodiment of the present application.

[0207] like Figures 7-9As shown, in some possible embodiments, along the radial direction of the pen body assembly 100, the wall of the magnet mounting cavity C on the side facing the first sliding cover magnet 610 and the second sliding cover magnet 630 has a communication port O, which helps to reduce the influence of the wall of the magnet mounting cavity C on the magnetic force generated by the pen body magnet 620 and the first sliding cover magnet 610 and the second sliding cover magnet 630. The magnetic force generated by the pen body magnet 620 and the first sliding cover magnet 610 and the second sliding cover magnet 630 is large, which is beneficial to drive the sliding cover assembly 200 to slide and to make the electrical contact part and the grounding part 400 make stable and reliable electrical contact.

[0208] For example, the connection port O can be through which magnetic lines of force generated by the pen body magnet 620 pass.

[0209] For example, the connection port O can be a strip-shaped opening extending along the axial direction of the pen body assembly 100.

[0210] In the example where the tail structure segment 111 has a groove G1, the connecting port O connects the groove G1 with the magnet mounting cavity C.

[0211] In some examples, both the metal structure 210 and the tail structure segment 111 are made of non-ferromagnetic metal to allow magnetic lines of force to pass through them.

[0212] Figure 10 A partial perspective view of the sliding cover assembly of another stylus provided in this application embodiment when it is in the closed position. Figure 11 for Figure 10 A partial perspective view of the stylus's sliding cover assembly in the open position.

[0213] like Figure 10 , Figure 11 As shown, in some possible embodiments, the closing contact portion 510 includes a second closing contact sub-portion 512, and the grounding portion 400 includes a second grounding sub-portion 420. The second grounding sub-portion 420 is located on the outer side of the tail structure segment 111, and the second closing contact sub-portion 512 is located on the inner side of the sliding structure 211.

[0214] When the sliding cover assembly 200 is in the closed position, at least a portion of the second closing contact portion 512 is opposite to the second grounding portion 420 along the radial direction of the pen body assembly 100. At least one of the second closing contact portion 512 and the second grounding portion 420 undergoes elastic deformation under the action of the magnetic force generated by the first sliding cover magnet 610 and the pen body magnet 620, so that the second closing contact portion 512 is pressed against the second grounding portion 420, and the second closing contact portion 512 and the second grounding portion 420 are in electrical contact.

[0215] Thus, when the sliding cover assembly 200 is in the closed position, the metal structural component 210 can be stably and reliably grounded through the electrical contact between the second closing contact portion 512 and the second grounding portion 420. Furthermore, the structure that grounds the metal structural component 210 when the sliding cover assembly 200 is in the closed position has minimal impact on the relative sliding of the sliding cover assembly 200 and the tail section 111, allowing for smooth opening and closing of the sliding cover assembly 200 while simultaneously grounding the metal structural component 210 when the sliding cover assembly 200 is in the closed position.

[0216] For example, a portion of the outer side of the tail structure segment 111 forms a second grounding part 420.

[0217] For example, a portion of the inner side of the sliding structure 211 forms a second closed contact portion 512.

[0218] In some possible implementations, along the radial direction of the pen body assembly 100, a first sliding cover magnet 610 is fixedly disposed on the outside of a second closing contact portion 512, at least a portion of the second closing contact portion 512 is opposite to the first sliding cover magnet 610, and at least a portion of the second grounding portion 420 is opposite to the pen body magnet 620.

[0219] This allows the second closing contact portion 512 to deform towards the second grounding portion 420 when the sliding cover assembly 200 is in the closed position, so that the second closing contact portion 512 can be pressed against the second grounding portion 420. In addition, the first sliding cover magnet 610 is less likely to detach from the sliding structure 211.

[0220] In some possible implementations, at least a portion of the second closed contact portion 512 is opposite to the second magnetic pole 612 along the radial direction of the pen body assembly 100, and at least a portion of the second ground portion 420 is opposite to the fourth magnetic pole 622.

[0221] This allows the second closing contact portion 512 to deform toward the second grounding portion 420 when the sliding cover assembly 200 is in the closed position, so that the second closing contact portion 512 can be pressed against the second grounding portion 420.

[0222] For example, when the sliding cover assembly 200 is in the closed position, the radial magnetic attraction force generated between the second magnetic pole 612 and the fourth magnetic pole 622 can press the second closing contact portion 512 into the second grounding portion 420.

[0223] When the sliding cover assembly 200 slides to the point where the second magnetic pole 612 and the third magnetic pole 621 are opposite each other, the magnetic repulsion force generated by the second magnetic pole 612 and the third magnetic pole 621 can cause the second closed contact portion 512 and the second ground portion 420 to deform away from each other, so as to facilitate the smooth sliding of the sliding assembly.

[0224] Figure 12 This application provides a cross-sectional schematic diagram of a stylus at the magnet on the pen body, representing another embodiment of the present application. Figure 12 In the middle, the sliding cover assembly 200 is in the closed position.

[0225] like Figure 12 As shown, in some examples, the outer surface of the sliding structure 211 has a third groove G4, in which the first sliding cover magnet 610 is fixedly disposed. Along the radial direction of the pen body assembly 100, at least a portion of the second closing contact portion 512 is located inside the third groove G4 and opposite to the first sliding cover magnet 610.

[0226] In this way, the second closed contact portion 512 can easily deform radially along the pen body assembly 100 under the magnetic force generated by the first sliding cover magnet 610, which facilitates the second closed contact portion 512 being pressed against the second grounding portion 420. In addition, it also helps to reduce the size of the stylus 1.

[0227] In the example where the tail structure section 111 has a groove G1, the second grounding part 420 is located on the groove wall of the groove G1. Specifically, the second grounding part 420 is located on the groove wall of the groove G1 on the side near the magnet mounting cavity C.

[0228] For example, at least a portion of the groove wall of the chute G1 near the magnet mounting cavity C forms a second grounding part 420.

[0229] In some possible implementations, the first sliding cover magnet 610 is a conductor and is electrically connected to the second closing contact portion 512.

[0230] In this way, when the sliding cover assembly 200 is in the closed position, the second closing contact portion 512 can make electrical contact with the second grounding portion 420 through the first sliding cover magnet 610 to achieve grounding of the metal structure 210. At this time, the first sliding cover magnet 610 can be disposed on the inner side of the second closing contact portion 512 along the radial direction of the pen body assembly 100.

[0231] Figure 13 This application provides a cross-sectional schematic diagram of a stylus at the magnet on the pen body, representing another embodiment of the present application. Figure 13 In the middle, the sliding cover assembly 200 is in the closed position.

[0232] like Figure 13As shown, in the example where the tail section 111 has a groove G1 and the wall of the magnet mounting cavity C has a communication port O, the second grounding part 420 is located on the groove wall of the groove G1 near the magnet mounting cavity C, and is located on the side of the communication port O in the width direction of the groove G1. For example, the communication port O is provided on both sides of the second grounding part 420 in the width direction of the groove G1.

[0233] like Figure 10 , Figure 11 As shown, in some possible embodiments, the opening contact portion 520 includes a second opening contact sub-portion 522. The second opening contact sub-portion 522 is located on the inner side of the sliding structure 211 of the metal structure 210. When the sliding cover assembly 200 is in the open position, at least a portion of the second opening contact sub-portion 522 is opposite to the second ground sub-portion 420 of the grounding portion 400 along the radial direction of the pen body assembly 100. At least one of the second opening contact sub-portion 522 and the second ground sub-portion 420 undergoes elastic deformation under the action of the magnetic force generated by the second sliding cover magnet 630 and the pen body magnet 620, so that the second opening contact sub-portion 522 is pressed against the second ground sub-portion 420, and the second opening contact sub-portion 522 and the second ground sub-portion 420 are in electrical contact.

[0234] Thus, when the sliding cover assembly 200 is in the open position, the metal structural component 210 can be stably and reliably grounded through the electrical contact between the second opening contact portion 522 and the second grounding portion 420. Furthermore, the structure that grounds the metal structural component 210 when the sliding cover assembly 200 is in the open position has minimal impact on the relative sliding of the sliding cover assembly 200 and the tail section 111, allowing for smooth opening and closing of the sliding cover assembly 200 while simultaneously grounding the metal structural component 210 when the sliding cover assembly 200 is in the open position.

[0235] For example, a portion of the inner side of the sliding structure 211 forms a second opening contact portion 522.

[0236] In some possible implementations, along the radial direction of the pen body assembly 100, the second sliding magnet 630 is fixedly disposed on the outside of the second opening contact portion 522, at least a portion of the second opening contact portion 522 being opposite to the second sliding magnet 630.

[0237] This allows the second opening contact portion 522 to deform towards the second grounding portion 420 when the sliding cover assembly 200 is in the open position, facilitating the pressing of the second opening contact portion 522 against the second grounding portion 420. Furthermore, the second sliding cover magnet 630 is less likely to detach from the sliding structure 211.

[0238] In some examples, the outer surface of the sliding structure 211 has a fourth groove G5, and the second sliding magnet 620 is fixedly disposed in the fourth groove G5. Along the radial direction of the pen body assembly 100, at least a portion of the second opening contact portion 522 is located inside the fourth groove G5 and opposite to the second sliding magnet 620.

[0239] In this way, the second opening contact portion 522 can easily deform radially along the pen body assembly 100 under the magnetic force generated by the second sliding cover magnet 620, which facilitates the second opening contact portion 522 being pressed against the second grounding portion 420. In addition, it also helps to reduce the size of the stylus 1.

[0240] In some possible implementations, the second sliding cover magnet 630 is a conductor and is electrically connected to the second opening contact portion 522.

[0241] In this way, when the sliding cover assembly 200 is in the open position, the second opening contact portion 522 can make electrical contact with the second grounding portion 420 through the second sliding cover magnet 630 to achieve grounding of the metal structure 210. At this time, the second sliding cover magnet 630 can be disposed on the inner side of the second opening contact portion 522 along the radial direction of the pen body assembly 100.

[0242] In some possible implementations, at least a portion of the second opening contact portion 522 is opposite to the fifth magnetic pole 631 along the radial direction of the pen body assembly 100.

[0243] This allows the second opening contact portion 522 to deform toward the second grounding portion 420 when the sliding cover assembly 200 is in the open position, so that the second opening contact portion 522 can be pressed against the second grounding portion 420.

[0244] For example, when the sliding cover assembly 200 is in the open position, the magnetic attraction force generated between the fifth magnetic pole 631 and the fourth magnetic pole 622 along the radial direction of the pen body assembly 100 can press the second opening contact portion 522 into the second grounding portion 420.

[0245] Figure 14 A partial perspective view of the sliding cover assembly of another stylus provided in this application embodiment when it is in the closed position. Figure 15 for Figure 14 A partial perspective view of the stylus's sliding cover assembly in the open position.

[0246] like Figure 14 , Figure 15As shown, in some possible embodiments, the stylus 1 further includes a flexible conductive element 700. One end of the flexible conductive element 700 is connected to the grounding portion 400, and the other end of the flexible conductive element 700 is connected to the electrical connection portion 500. The electrical connection portion 500 is electrically connected to the grounding portion 400 through the flexible conductive element 700.

[0247] In this way, during the sliding process of the sliding cover assembly 200, the metal structural component 210 can be stably and reliably grounded, which helps to reduce the failure rate of the stylus 1.

[0248] For example, the flexible conductive element 700 may include, but is not limited to, conductive cloth.

[0249] For example, the flexible conductive element 700 includes a first end, a second end, and a flexible connecting segment located between the first end and the second end. The first end is fixed and electrically connected to the electrical connection portion 500, and the second end is fixed and electrically connected to the ground portion 400. The surface of the flexible connecting segment has an insulating layer, making it difficult for the flexible conductive element 700 to make electrical contact with other devices of the stylus 1.

[0250] For example, at least one of the electrical connection portion 500 and the grounding portion 400 is bonded to the flexible conductive member 700 by conductive adhesive, making it easier to connect the flexible conductive member 700.

[0251] For example, the electrical connection portion 500 is located on the outer surface of the metal structure 210. Specifically, the electrical connection portion 500 is located on the outer surface of the sliding structure 211.

[0252] This design allows for a larger connection surface between the electrical connection portion 500 and the flexible conductive element 700, facilitating a stable and reliable electrical connection between them. Furthermore, the flexible conductive element 700 has minimal impact on the sliding of the sliding cover assembly 200. Additionally, when the sliding cover assembly 200 is in the closed position, the redundant portion of the flexible conductive element 700 can be accommodated on the side of the metal structural member 210 away from the head structure segment 121, which is beneficial for accommodating the flexible conductive element 700.

[0253] For example, a portion of the outer side of the sliding structure 211 forms an electrical connection portion 500.

[0254] For example, the end of the metal structural member 210 away from the head structural segment 121 has a connecting hole; specifically, the connecting structure 212 has a connecting hole. The flexible conductive member 700 passes through the connecting hole.

[0255] For example, the grounding part 400 is located on the inner side of the tail structure section 111, and the end of the tail structure section 111 away from the head structure section 121 is an open structure. The flexible conductive element 700 passes through the open structure at the end of the tail structure section 111 away from the head structure section 121.

[0256] This design allows for a larger connection surface between the grounding part 400 and the flexible conductive element 700, facilitating a stable and reliable electrical connection between them. Furthermore, the flexible conductive element 700 has minimal impact on the sliding of the sliding cover assembly 200.

[0257] For example, a portion of the inner side of the tail structure segment 111 forms a grounding portion 400.

[0258] Figure 16 A partial perspective view of the sliding cover assembly of another stylus provided in this application embodiment when it is in the closed position. Figure 17 for Figure 16 A partial perspective view of the stylus's sliding cover assembly in the open position.

[0259] like Figure 16 , Figure 17 As shown, in some possible embodiments, a conductive elastic element 800 is provided between the metal structural member 210 and the tail structural section 111. The conductive elastic element 800 is fixed and electrically connected to one of the electrical connection portion 500 and the grounding portion 400. When the sliding cover assembly 200 is in the closed position, the conductive elastic element 800 is pressed against the other of the electrical connection portion 500 and the grounding portion 400 and makes electrical contact with the other of the electrical connection portion 500 and the grounding portion 400.

[0260] In this way, by means of the conductive elastic element 800, the metal structural component 210 can be grounded when the sliding cover assembly 200 is in the closed position, with minimal impact on the sliding of the sliding cover assembly 200, which helps to reduce the failure rate of the stylus 1.

[0261] For example, the conductive elastic element 800 may include, but is not limited to, an arc-shaped spring.

[0262] For example, the grounding portion 400 includes a fourth grounding sub-portion 440, which is located on the outer side of the tail structure segment 111. The closing contact portion 510 includes a third closing contact sub-portion 513, which is located on the inner side of the sliding structure 211. The conductive elastic element 800 is fixedly connected to the tail structure segment 111 and electrically connected to the fourth grounding sub-portion 440. When the sliding cover assembly 200 is in the closed position, the conductive elastic element 800 is in electrical contact with the third closing contact sub-portion 513 to facilitate grounding of the metal structure 210.

[0263] For example, the opening contact portion 520 also includes a third opening contact portion 523, which is located on the inner side of the sliding structure 211 and on the side of the third closing contact portion 513 near the head structure segment 121. When the sliding cover assembly 200 is in the open position, the conductive elastic element 800 makes electrical contact with the third opening contact portion 523 to facilitate grounding of the metal structure component 210.

[0264] For example, the inner surface of the sliding structure 211 has a first arc-shaped groove G6 and a second arc-shaped groove G7. The second arc-shaped groove G7 is located between the first arc-shaped groove G6 and the head structure segment 121. The third closing contact portion 513 is located on the groove wall of the first arc-shaped groove G6, and the third opening contact terminal is located on the groove wall of the second arc-shaped groove G7. When the conductive elastic member 800 slides into the first arc-shaped groove G6, the conductive elastic member 800 abuts against the groove wall of the first arc-shaped groove G6 to drive the sliding cover assembly 200 to slide towards the head structure segment 121. When the conductive elastic member 800 slides into the second arc-shaped groove G7, the conductive elastic member 800 abuts against the groove wall of the second arc-shaped groove G7 to drive the sliding cover assembly 200 to slide away from the head structure segment 121.

[0265] This facilitates automatic opening and closing after the sliding cover assembly 200 slides to the preset position.
