[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0033] like Figures 1 to 6 As shown, an embodiment of the utility model provides a stylus pen detection device, which includes a housing 100, a magnetic component 200 and a detection component 300. The housing 100 has a housing cavity 110, and the magnetic component 200 is movably arranged in the housing cavity 110. The magnetic component 200 has a relatively arranged pen-lifting position and a pen-releasing position. When the stylus pen is close to the housing 100, the magnetic component 200 is in the pen-releasing position, and when the stylus pen is away from the housing 100, the magnetic component 200 is in the pen-lifting position. The magnetic component 200 can switch from the pen-lifting position to the pen-releasing position under the magnetic attraction of the stylus pen. The detection component 300 is arranged in the housing 100, and a sensing device is arranged on the detection component 300. The sensing device is arranged corresponding to the magnetic component 200, and the sensing device can sense the change of the magnetic field when the magnetic component 200 switches between the pen-lifting position and the pen-releasing position.

[0034] By applying the technical solution of the utility model, the magnetic component 200 can be driven by the magnetism of the stylus. When the stylus is placed close to the housing 100, the magnetic component 200 can move toward the stylus under the magnetic attraction of the stylus to switch to the pen-putting position. When the user lifts the stylus and moves the stylus away from the housing 100, the magnetic component 200 is separated from the magnetic attraction of the stylus, and the magnetic component 200 can switch to the pen-putting position. During the switching of the magnetic component 200 between the pen-lifting position and the pen-putting position, the sensing device on the detection component 300 can sense the position change of the magnetic component 200 according to the change of the magnetic field when the magnetic component 200 moves, so that the touch display device can judge the current position state of the stylus. In the present application, by setting the magnetic component 200 and the detection component 300 in the shell 100, the integration level of the stylus detection device can be improved. It is only necessary to fix the shell 100 in the touch display device, and there is no need to open holes on the outer shell of the touch display device or set contacts for connection, thereby improving the appearance, reducing the tolerance and environmental impact during assembly, and improving the assembly effect and production efficiency.

[0035] Furthermore, the stylus pen detection device further includes a control board 310, on which a sensing device is disposed, and the sensing device is electrically connected to the control board 310. By arranging the sensing device on the control board 310, the signal of the magnetic field change of the magnetic component 200 sensed by the current sensing device can be judged and transmitted, so that the touch display device can judge the change of the stylus pen position.

[0036] Specifically in the present application, the magnetic component 200 includes a magnet 210 and a fixing sleeve 220. The fixing sleeve 220 has an installation cavity 221. A snap-fit ​​structure is provided on the inner wall of the installation cavity 221. The magnet 210 is fixedly connected to the fixing sleeve 220 through the snap-fit ​​structure. Through the above configuration, the magnetic component 200 is configured as a combination of the magnet 210 and the fixing sleeve 220, which can facilitate the processing and forming of the magnetic component 200. The magnet 210 provides magnetism for the magnetic component 200, and the magnet 210 is fixed in the fixing sleeve 220, which can facilitate the selection of the overall shape of the magnetic component 200. When the magnetic component 200 moves in the housing 100, the overall wear of the magnetic component 200 can also be reduced, thereby ensuring the service life of the magnetic component 200.

[0037] Specifically, the magnet 210 can be made of materials such as neodymium iron boron magnet or aluminum nickel cobalt magnet.

[0038] Specifically, the fixing sleeve 220 can be made of plastic or polymer material to facilitate the processing and molding of the fixing sleeve 220, reduce the wear of the fixing sleeve 220 when moving in the shell 100, increase the service life of the magnetic component 200, and reduce the maintenance cost of the stylus detection device.

[0039] In some embodiments of the present application, the snap-fit ​​structure includes a snap-fit ​​protrusion, and a plurality of snap-fit ​​protrusions are provided. The plurality of snap-fit ​​protrusions are arranged at annular intervals on the inner walls at both ends of the fixing sleeve 220, and the magnet 210 is snap-fitted into the fixing sleeve 220 via the snap-fit ​​protrusions.

[0040] In some other feasible embodiments of the present application, the snap-fit ​​structure includes a snap-fit ​​groove, which is arranged on the side wall of the fixing sleeve 220 , and the magnet 210 is snap-fitted with the fixing sleeve 220 through the snap-fit ​​groove to facilitate the installation and fixation of the magnet 210 .

[0041] Specifically in the present application, a partition 230 is provided in the fixed sleeve 220. The side of the partition 230 away from the sensing device cooperates with the fixed sleeve 220 to form an installation cavity 221. The side of the partition 230 close to the sensing device cooperates with the fixed sleeve 220 to form an avoidance cavity 222. When the magnetic component 200 is switched to the pen-lifting position, the sensing device avoids the magnetic component 200 through the avoidance cavity 222. Through the above arrangement, the partition 230 can separate the inner cavity of the fixed sleeve 220 into an installation cavity 221 and an avoidance cavity 222. The installation cavity 221 is used to install the magnetic component 200, and the avoidance cavity 222 is used to avoid the sensing device. When the magnetic component 200 is switched to the pen-lifting position, the avoidance cavity 222 can prevent the magnet 210 from directly colliding with the sensing device, causing the movement failure of the magnetic component 200, and can also prevent the sensing device from interfering with the movement trajectory of the magnetic component 200, thereby ensuring the movement stability of the magnetic component 200.

[0042] Furthermore, the clamping structure may be disposed on a side wall of the mounting cavity 221 .

[0043] Furthermore, a plurality of process grooves may be provided at annular intervals on the side wall of the mounting cavity 221, that is, the side wall of the fixing sleeve 220, so that the side wall of the fixing sleeve 220 may be deformed to a certain extent, so that the magnet 210 can smoothly enter the mounting cavity 221, thereby facilitating the assembly of the magnetic component 200.

[0044] Reference Figures 1 to 3As shown, in the first embodiment of the present application, a threaded structure is provided between the outer wall of the fixing sleeve 220 and the housing 100, the sensing device includes a wire 320, and the magnetic component 200 can rotate relative to the wire 320 through the threaded structure. Through the above arrangement, when the magnetic component 200 switches between the pen-lifting position and the pen-putting position, due to the threaded structure between the side wall of the fixing sleeve 220 and the housing 100, the linear motion of the magnetic component 200 will be converted into a rotation along the circumferential direction, and the wire 320 is in the magnetic field formed by the magnetic component 200. The rotation of the magnetic component 200 will continuously drive the magnetic flux lines to rotate, and the wire 320 will generate an induced current when cutting the magnetic flux lines. In this way, according to the direction of the induced current generated in the wire 320 and the magnitude of the voltage, the current motion state and position of the magnetic component 200 can be determined, thereby realizing the detection of the position of the stylus at this time.

[0045] Reference Figures 4 to 6 As shown, in the second embodiment of the present application, the sensing device includes a Hall element 330. The Hall element 330 can determine the current motion state and position of the magnetic component 200 according to the change in magnetic field strength when the magnetic component 200 switches between the pen lifting position and the pen putting position, thereby realizing the detection of the position of the stylus at this time.

[0046] In the second embodiment of the present application, a guiding structure may be provided between the fixing sleeve 220 and the inner wall of the accommodating chamber 110 to guide the movement of the magnetic component 200 between the pen lifting position and the pen putting position.

[0047] Specifically, the guide structure may be a guide rod or a guide groove or other structures, as long as it can guide the magnetic component 200 , and no specific limitation is made in the present application.

[0048] Furthermore, the detection component 300 is also provided with a reminder device 400, which is electrically connected to the control board 310. When the magnetic component 200 is switched from the pen-putting position to the pen-lifting position, the reminder device 400 can send a reminder signal. Through the above configuration, the user can be reminded not according to the display screen of the touch display device, such as when carrying or placing it in a backpack. Through the reminder of the reminder device 400, the user can judge the current position state of the touch pen, which is convenient for the user to use when it is inconvenient to directly view the display screen.

[0049] Specifically, the reminder device 400 can be a buzzer, a vibration motor or other devices, as long as it can serve to remind the user.

[0050] In the present application, the stylus pen detection device further includes an elastic component 500, which is disposed in the accommodating cavity 110, one end of the elastic component 500 abuts against the inner wall of the housing 100, and the other end of the elastic component 500 abuts against the magnetic component 200, and the elastic component 500 is used to provide an elastic force to the magnetic component 200 to switch from the pen-putting position to the pen-lifting position. Through the above arrangement, when the stylus pen is away from the stylus pen detection device, the magnetic component 200 can be driven by the elastic component 500 to switch from the pen-putting position to the pen-lifting position, thereby improving the stability of the movement of the magnetic component 200.

[0051] Specifically, the elastic component 500 includes a spring sheet 510 and a gasket 520. The gasket 520 is arranged on a side of the spring sheet 510 close to the magnetic component 200. The spring sheet 510 is used to provide an elastic force to the magnetic component 200 to switch from the pen-putting position to the pen-lifting position. Through the above arrangement, the spring sheet 510 can provide an elastic force for the magnetic component 200 to move, and by providing the gasket 520, it can be ensured that the magnetic component 200 can move stably under the drive of the spring sheet 510.

[0052] In other embodiments of the present application, the elastic component 500 may also include a spring, a leaf spring or other elastic members, as long as they can provide elastic force to the magnetic component 200 .

[0053] Specifically in the present application, a limiter is provided on the inner wall of the housing 100, and the limiter is used to limit the displacement of the magnetic component 200 when switching from the pen-putting position to the pen-lifting position. Through the above arrangement, the limiter can limit the movement range of the magnetic component 200 and ensure the stability of the movement stroke of the magnetic component 200.

[0054] Specifically, the limiting member may be in the form of a limiting protrusion or a limiting groove, as long as the limiting of the magnetic component 200 can be achieved.

[0055] According to an embodiment of the utility model, a touch display device is also provided, and the touch display device includes the above-mentioned stylus detection device. The stylus detection device provided in the present application accommodates the magnetic component 200 and the detection component 300 through the housing 100, and the stylus detection device forms an integrated module. By applying the above-mentioned stylus detection device to the touch display device, it is possible to facilitate the inspection of the finished product of the stylus detection device. There is no need to equip the various parts on the touch display device for quality inspection. Only the stylus detection device needs to be quality inspected. The functional inspection step is pre-placed before the assembly of the whole machine, which reduces the probability of rework and reduces the overall production and maintenance costs of the touch display device.

[0056] Specifically, the control board 310 of the touch display device is further provided with an output terminal, and the output terminal is used to be electrically connected to the main board of the stylus pen detection device to receive a control signal from the control board 310 .

[0057] Specifically, the housing 100 of the stylus pen detection device is also provided with a connection structure such as a connection plate to facilitate assembly with the touch display device. The connection structure may be a connection plate or a connection hole.
