Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The embodiment of the application provides a vapour-pressure type carries a pen to detect structure for detect the state of placing of electron device writing pen. As shown in fig. 1 to 4, the pneumatic pen-lifting detection structure 100 includes a pneumatic sensor 110, a sealing member 120, and a mounting member 130.
The air pressure sensor 110 is provided with a sensing terminal 111 for generating a sensing signal by the air pressure sensor 110 by sensing a pressure change. The sealing member 120 is enclosed in the sensing end 111, an air cavity 121 is provided in the sealing member 120, and the air cavity 121 is communicated with the sensing end 111. The air pressure sensor 110 is mounted on the mounting member 130, and the mounting member 130 is further used for placing the stylus 220, so that the stylus 220 squeezes the air in the air chamber 121 during the process of approaching the mounting member 130 to trigger the air pressure sensor 110 to generate a sensing signal.
The air pressure sensor 110 is further connected to the conductive circuit 122, so that the air pressure sensor 110 can be connected to a rear end control system of the electronic device through the conductive circuit 122, a sensing signal generated by the air pressure sensor 110 is transmitted to the rear end control system through the conductive circuit 112, and the rear end control system analyzes the received control signal to determine the placement state of the stylus 220.
In the pneumatic pen lifting detection structure 100 provided in the embodiment of the present application, the stylus 220 is mounted on the mounting member 130, so that the stylus 220 presses the gas in the air chamber 121 of the sealing member 120 to generate pressure variation in the process of approaching the mounting member 130, and the pressure variation triggers the sensing end 111 of the air pressure sensor 110 communicated with the air chamber 121 to generate a sensing signal, so that the placement state of the stylus 220 can be determined according to the sensing signal. In this application, the stylus 220 can trigger the air pressure sensor 110 only after the pressure variation is generated by the air in the extrusion air cavity 121, so as to improve the accuracy of the detection result of the air pressure type pen lifting detection structure 100. The sealing member 120 is covered on the sensing end 111 of the air pressure sensor 110, and the air chamber 121 can be communicated with the sensing end 111 by changing the structure of the sealing member 120 to match the installation position of the air pressure sensor 110, so that the air pressure sensor 110 can be flexibly installed. For example, concealed mounting of the air pressure sensor 110 within the mount 130 is facilitated.
As shown in fig. 3, in some exemplary embodiments, the mounting member 130 is provided with a mounting hole 131, and the mounting hole 131 is abutted with the air cavity 121, so that when the stylus pen 220 approaches the mounting member 130, the end of the mounting hole 131 can be blocked, and the air in the mounting hole 131 and the air cavity 121 can be squeezed to trigger the sensing end 111 to generate a sensing signal. The stylus pen 220 and the air pressure sensor 110 may be respectively disposed at two opposite ends of the mounting hole 131, for example, the structure of the mounting member 130 near the mounting hole 131 may be a plate-shaped structure, and the stylus pen 220 and the air pressure sensor 110 may be mounted at two opposite sides of the plate-shaped structure, and one side of the plate-shaped structure on which the stylus pen 220 is mounted faces a user, so that the air pressure sensor 110 is hidden and mounted in the mounting member 130, thereby beautifying the appearance of the electronic device on which the air pressure type pen lifting detection structure 100 is mounted.
In some exemplary embodiments, the pneumatic pen-lifting detection structure 100 further includes a limiting member 150, and the limiting member 150 is configured to fix the stylus 220 on the surface of the mounting member 130, and enable the stylus 220 to press the air in the air chamber 121 during the process of approaching the mounting member 130, so as to trigger the air pressure sensor 110 to generate the sensing signal. The limiting member 150 is further configured to fix the position of the stylus 220 on the mounting member 130, so as to prevent the stylus 220 from falling off the mounting member 130, or prevent the stylus 220 from shaking freely under the action of a slight external force.
The manner of installing the stylus 220 on the mounting member 130 to press the air in the air chamber 121 may be: the stylus 220 has a certain speed when approaching the installation component 130, so that the stylus 220 drives the sealing component 120 to vibrate after approaching the installation component 130, thereby extruding the gas in the gas cavity 121 to generate pressure change; or stylus 220 is mounted on mounting member 130 to directly press seal 120 to deform; or a combination of the two.
When the stylus pen 220 approaches the mounting member 130 at a certain speed to squeeze the air in the air chamber 121, specifically, as shown in fig. 4, the limiting member 150 may include a first limiting portion 151 and a second limiting portion 152, the first limiting portion 151 and the second limiting portion 152 are respectively used for being mounted on the mounting member 130 and the stylus pen 220, one of the first limiting portion 151 and the second limiting portion 152 is an attracting magnet, and the other is an iron element, or both the first limiting portion 151 and the second limiting portion 152 are attracting magnets. When the stylus pen 220 is stored, the stylus pen 220 can be fixed to the mounting member 130 by suction by bringing the stylus pen 220 close to the mounting member 130. For example, the first limiting member 150 may be an attracting magnet, and the attracting magnet is mounted on the surface of the mounting member 130 on the same side as the air pressure sensor 110, and the second limiting member 150 may be an iron-made element and may be a part of the housing of the stylus pen 220. In addition, when the stylus pen 220 is stored, the stylus pen 220 can be fixed on the mounting member 130 by being attracted by the attracting magnet facing the first limiting portion 151 of the second limiting member 150 made of iron on the stylus pen 220, and in the process that the stylus pen 220 moves to the attracting magnet to be attached to the surface of the mounting member 130, the stylus pen 220 can obtain a certain speed under the action of the magnetic attraction force to squeeze the air in the air cavity 121, so that the pressure in the air cavity 121 changes.
The sealing member 120 is sealed at the sensing end 111, so that the sensing end 111 can capture all pressure changes in the air cavity 121, and the sensing sensitivity of the sensing end 111 to the pressure changes in the air cavity is improved. In some embodiments, the sealing element 120 may be made of deformable silicone foam, and the surface of the sealing element 120 made of the silicone foam may abut against the surface of the mounting element 130 or the surface of the air pressure sensor 110 to achieve a sealing effect.
Specifically, as shown in fig. 3, in some exemplary embodiments, the sealing member 120 is a hollow cylindrical sealing member, the air chamber 121 penetrates through the sealing member 120 and is connected to two outer side surfaces of the sealing member 120 opposite to each other, and the two outer side surfaces of the sealing member 120 are respectively abutted to the surface of the air pressure sensor 110 and the surface of the mounting member 130 to achieve a sealing effect. The air cavity 121 in the sealing element 120 is communicated with the mounting hole 131, and the sealing element 120 and the air pressure sensor 110 are arranged on the same side of the mounting element 130 and are hidden and mounted, so that the appearance of the air pressure sensor is beautified. Further, the sealing member 120 may be a sealing member or a hollow square sealing member, and the air chamber 121 and the mounting hole 131 may be coaxially disposed, so that when the stylus pen 220 contacts the mounting hole 131 at a certain speed and presses the air in the mounting hole 131, the air in the mounting hole 131 may smoothly enter the air chamber 121 to press the air in the air chamber 121, so that the pressure in the air chamber 121 varies.
As shown in fig. 5, in some exemplary embodiments, the sealing member 120 may include a position-limiting portion 122 and an abutting portion 123 integrally provided, and the air chamber 121 penetrates the position-limiting portion 122 and the abutting portion 123; the limiting part 122 penetrates through the mounting hole 131, and the outer surface of the limiting part 122 is attached to the wall surface of the mounting hole 131; the outer diameter of the abutting portion 123 is larger than the outer diameter of the stopper portion 122, and the surface of the abutting portion 123 connected to the stopper portion 122 and the other surface opposite to the surface are abutted against the surface of the mounting member 130 and the surface of the air pressure sensor 110, respectively. During assembly, the limiting portion 122 can be inserted into the mounting hole 131 to guide the mounting position of the sealing element 120, the air pressure sensor 110 is then pushed to contact the abutting portion 123, and the abutting portion 123 is covered on the sensing end 111 until the two opposite surfaces of the abutting portion 123 abut against the mounting element 130 and the air pressure sensor 110 respectively, so that stable sealing connection among the mounting element 130, the air pressure sensor 110 and the sealing element 120 is completed.
The limiting portion 122 is disposed through the mounting hole 131, and an end of the limiting portion 122 can be received in the mounting hole 131 to hide the limiting portion 122. As shown in fig. 5 and 6, the end of the position-limiting part 122 may also extend to be flush with the surface of the mounting member 130 or extend out of the mounting hole 131, so that the stylus 220 directly presses the air in the air chamber 121 when approaching the mounting member 130. When the end of the limiting member 150 is flush with the surface of the mounting member 130 or extends out of the mounting hole 131, the limiting portion 122 can be made of a deformable material, so that the stylus 220 extrudes the end of the limiting portion 122 to deform when approaching the mounting member 130, and further extrudes the gas in the gas chamber 121.
As shown in fig. 6, in some exemplary embodiments, when the end of the position-limiting portion 122 extends out of the mounting hole 131, one end of the position-limiting portion 122 away from the abutting portion 123 is provided with a deformation portion 124, the deformation portion 124 extends out of the mounting hole 131, the deformation portion 124 is configured as a bowl-shaped structure with gradually decreasing thickness in the direction away from the abutting portion 123, the end with the thinnest thickness of the end of the deformation portion 124 is provided with an opening 1241 communicating with the air cavity 121, and the end of the deformation portion 124 provided with the opening 1241 is used for abutting against the stylus 220. The sealing member 120 can be made of materials such as silica gel foam which can generate deformation, and when the stylus pen 220 is abutted to the deformation part 124 of the bowl-shaped structure, the deformation part 124 generates deformation to extrude gas in the gas cavity 121. Further, the deformation part 124 is set to be a bowl-shaped structure with the thickness gradually decreasing towards the direction away from the abutting part 123, so that the stylus pen 220 can be more easily extruded into the air of the air cavity 121 when being extruded and deformed by the deformation part 124, and the required pressure change can be obtained.
In some exemplary embodiments, the surface of the mounting element 130 may further include a mounting groove 132 for placing the pen 220, the mounting groove 132 is communicated with the mounting hole 131, and a surface of the limiting portion 122 at an end away from the abutting portion 123 is connected to a wall surface of the mounting groove 132 or is accommodated in the mounting groove 132. When the surface of the end of the limiting portion 122 far from the abutting portion 123 is connected to the wall surface of the mounting groove 132, the surface of the limiting portion 122 can be smoothly connected to the mounting groove 132, so that the stylus pen 220 can be placed in the mounting groove 132 to be attached to or abutted against the wall surface of the mounting groove 132, and the surface of the stylus pen 220 can also be attached to or abutted against the surface of the limiting portion 122, thereby sealing the air cavity 121. When the surface of the end of the position-limiting portion 122 away from the abutting portion 123 is received in the mounting groove 132, the end of the position-limiting portion 122 away from the abutting portion 123 may extend out of the mounting hole 131 (for example, the deformation portion 124 extends out of the mounting hole 131), and the stylus 220 may press the deformation portion 124 to deform and seal the air cavity 121. Under the two conditions that the stylus pen 220 seals the air cavity 121, negative pressure can be generated in the air cavity 121 when the stylus pen 220 is subsequently taken down, and the air pressure sensor 110 can be further used for analyzing the pen lifting or accommodating state of the stylus pen 220 according to the detected negative pressure change.
The mounting groove 132 is a contour groove for placing the stylus 220, and the surface of the mounting wall 134 is attached to the surface of the stylus 220 to improve the stability of placing the stylus 220 in the mounting groove 132. For example, when the surface of the stylus 220 has a circular arc surface, the wall surface of the mounting groove 132 is also configured as a circular arc surface that conforms to the surface of the stylus 220. The first position-limiting portion 151 disposed on the mounting member 130 can be disposed in the mounting groove 132, for example, when the first position-limiting portion 151 of the position-limiting member 150 is an attracting magnet, the attracting magnet can be disposed on the surface of the mounting member 130 opposite to the mounting groove 132, and the attracting magnet can be orthographically projected into the region of the mounting groove 132. Further, the number of the attracting magnets may be set to be plural and installed side by side along the length direction of the stylus pen 220, or the attracting magnets may be bar magnets installed along the length direction of the stylus pen 220, which sufficiently improves the installation stability of the stylus pen 220 on the installation member 130.

In some embodiments, mounting member 130 may include a mounting portion 133 and a mounting wall 134 mounted to mounting portion 133, mounting portion 133 may include a first surface 1331 and a second surface 1332 disposed opposite to each other, mounting groove 132 for receiving stylus 220 may be provided on first surface 1331, and mounting wall 134, sealing member 120, and air pressure sensor 110 may be mounted on second surface 1332.
