Technical Field
[0001] This application relates to the technical field of electronic devices, and more particularly to a sensor device and an interactive flat panel device. Background Technology
[0002] Sensors play a crucial role in the technical implementation of interactive flat panels. To meet the needs of different users and facilitate sensor maintenance and upgrades, some interactive flat panels adopt the design of external sensor modules. However, existing external sensor modules are fixed to the frame of the interactive flat panel by screws. This installation structure has many shortcomings in terms of production, use and functional expansion, and a new installation structure is urgently needed to solve these problems. Utility Model Content
[0003] The purpose of this utility model embodiment is to provide a sensor device and an interactive flat panel device that can solve the above-mentioned problems existing in the prior art.
[0004] To achieve the above objectives, this application adopts the following technical solution:
[0005] On one hand, a sensor device is provided, comprising:
[0006] case;
[0007] The circuit board, including the sensor module, is installed inside the housing and is used to realize the functions of sensing and transmitting signals;
[0008] A magnetic attachment, installed inside or outside the housing, is used to attach to the back cover of the interactive flat panel to achieve the installation of the sensor device.
[0009] The sensor device of this application exhibits significant advantages in terms of ease of installation, convenient maintenance and upgrades, optimized user experience, functional expandability, and structural design and manufacturing advantages. Specifically:
[0010] By incorporating magnetic attachments, the sensor is magnetically attached to the back cover (iron alloy) of the interactive flat panel. This eliminates the complex pre-drilling process required during product manufacturing, simplifying the production process and reducing costs. During user operation, users can freely adjust the sensor's installation position according to their needs, without being limited by pre-set mounting holes, greatly improving flexibility and enhancing the user experience. Furthermore, when a sensor malfunctions or requires an upgrade, users can simply remove the external sensor module for replacement or repair without disassembling the entire interactive flat panel, significantly reducing maintenance and time costs. Additionally, with technological advancements and evolving user needs, users can easily add new sensor modules to existing interactive flat panels to achieve more functionality without requiring extensive modifications to the device.
[0011] Optionally, the housing includes an outer shell and an inner shell. The outer shell includes a first mounting portion and a second mounting portion. The first mounting portion protrudes in a first direction relative to the second mounting portion, or the second mounting portion protrudes in a first direction relative to the first mounting portion. With the first direction as the front, the front side of the first mounting portion is provided with a first opening, and the front side of the second mounting portion is provided with a third opening. The sidewalls adjacent to the first mounting portion and the second mounting portion are provided with a second opening communicating with the first opening and the third opening. The inner shell includes a first cover plate, a second cover plate, and a third cover plate connected in a stepped manner. The first cover plate, the second cover plate, and the third cover plate respectively cover the first opening, the second opening, and the third opening.
[0012] The circuit board is mounted on the first mounting part, and the magnetic suction component is mounted on the second mounting part.
[0013] In the housing structure design of the sensor device, the outer shell is provided with a first mounting part and a second mounting part, which respectively provide mounting space for the circuit board and the magnetic components. The inner corner structure formed by the two parts can be locked at the corner of the back shell and the frame of the interactive flat panel, forming a more stable mounting structure. The stepped through-opening structure formed on the outer shell provides a larger operating space for injection molding and machining processes, which is conducive to rapid demolding, ensuring product quality, and improving assembly convenience.
[0014] Optionally, the rear wall of the inner shell is provided with a first buckle, and the inner wall of the outer shell is provided with a corresponding second buckle, wherein the first buckle and the second buckle are engaged.
[0015] In the above embodiments, the snap-fit design of the first and second snap-fits ensures a secure connection between the inner and outer shells, effectively preventing loosening or detachment due to vibration or external forces during use. The snap-fit connection simplifies the assembly process, reduces the use of screws and other fasteners, improves assembly efficiency, and prevents screw heads from being exposed on the product's outer surface, maintaining a clean and aesthetically pleasing appearance. This enhances the overall quality and competitiveness of the product, meeting market demands for high-quality, user-friendly products.
[0016] Optionally, the first buckle is provided on the opposite sides of the first cover plate and the third cover plate.
[0017] In the above embodiment, by setting first buckles on the opposite sides of the first and third cover plates, symmetrical multi-point fixing between the inner shell and the outer shell is achieved. This design can disperse stress and improve the stability and reliability of the connection. Furthermore, the multi-point fixing design allows the inner shell to better maintain its connection with the outer shell when subjected to vibration or impact, thereby enhancing the vibration resistance of the entire sensor device.
[0018] Optionally, the inner wall of the outer shell is provided with a raised rib extending along the first direction, and the front end of the raised rib abuts against and supports the inner shell.
[0019] In the above embodiment, the front end of the convex rib abuts against the inner shell and limits the insertion depth of the inner shell. In conjunction with the snap-fit structure, it completely restricts the degree of freedom of movement of the inner shell. This design ensures the stable position of the inner shell inside the outer shell, making it less prone to shaking or loosening, thereby improving the structural reliability of the sensor device and helping to reduce damage and failure caused by vibration or external force.
[0020] Optionally, the circuit board is connected to a wire extending outside the housing; wherein, a wire-clamping boss is provided on one edge of the rear wall of the third cover plate, and the wire-clamping boss has a first wire-clamping recess; the side wall of the housing has a groove corresponding to the wire-clamping boss, and the bottom of the groove has a second wire-clamping recess, the wire-clamping boss is embedded in the groove, and the first wire-clamping recess and the second wire-clamping recess cooperate to clamp the wire.
[0021] In the above embodiment, the third cover plate corresponds to the third opening of the second mounting portion, and the second mounting portion provides mounting space for the magnetic component, located on the back of the interactive tablet during application. Conversely, the first mounting portion provides mounting space for the circuit board, located on the side of the interactive tablet during application. In this embodiment, the wires are led out from the second mounting portion corresponding to the third cover plate, that is, the wires are led out from the second mounting portion located on the back of the interactive tablet, avoiding the need to lead out the wires from the first mounting portion. This satisfies the requirement for circuit interconnection while reducing the thickness of the first mounting portion located on the side of the interactive tablet, and can directly hide the wires on the back of the interactive tablet. Obviously, this optimizes the neatness of the product appearance during application and improves the user's visual perception and user experience.
[0022] Optionally, the rear wall of the third cover plate is provided with a mounting recess, and the magnetic component is installed in the mounting recess.
[0023] In the above embodiment, the mounting recess provides a clear mounting position for the magnetic component, ensuring its accurate placement on the third cover plate. This precise positioning helps maintain the relative positional relationship between the magnetic component and other components, thereby improving the overall performance of the sensor device. Furthermore, the mounting recess effectively reduces the magnetic component's shaking and displacement on the third cover plate. During the use of the sensor device, it may be subjected to external forces such as vibration and impact; a stable magnetic component mounting ensures that its performance remains unaffected.
[0024] Optionally, the front wall of the third cover plate is provided with an anti-slip pad.
[0025] In the above embodiment, the front wall of the third cover plate is the surface that is close to the interactive flat panel when in use. The anti-slip pad installed at this position can directly contact the surface of the interactive flat panel, thereby effectively increasing the friction between the front wall of the third cover plate and the contact surface and preventing the sensor device from sliding or shifting during use.
[0026] Optionally, the first mounting portion protrudes in the first direction relative to the second mounting portion, and a first locking position is provided on the inner wall of the first mounting portion opposite to the first cover plate, and a second locking position is provided on the rear wall of the first cover plate, and the two opposite edges of the circuit board are respectively locked into the first locking position and the second locking position.
[0027] In the above embodiment, the space between the first mounting part and the first cover plate constitutes the assembly area of the circuit board. The first and second locking positions are located on both sides of this assembly area, providing clear boundaries and fixing points for the installation of the circuit board. During product assembly, the circuit board can be inserted into the first mounting part along the first direction and engaged with the first locking position to achieve pre-fixation of the circuit board; then the inner shell is closed, and the second locking position on the inner side of the inner shell can be engaged with the other edge of the circuit board to achieve complete fixation of the circuit board. In this structure, the circuit board can be vertically inserted into the first mounting part along the first direction, and due to the wide opening design of the Z-shaped opening on the outer shell, it allows the assembler to easily and accurately insert it, thus greatly shortening the assembly time. In addition, the circuit board is fixed immediately after the insertion and closing work is completed, without the need for other fixing methods. Compared with traditional bolt fixing or other complex installation methods, this locking method is simpler and faster, improving production efficiency.
[0028] Optionally, the first mounting portion protrudes in the first direction relative to the second mounting portion, and the third cover plate is provided with a first clearance groove, which is provided along the edge where the third cover plate and the second cover plate connect;
[0029] Alternatively, the second mounting portion protrudes in the first direction relative to the first mounting portion, and the second cover plate is provided with a first clearance groove, which is provided along the edge where the second cover plate connects to the first cover plate.
[0030] In the above embodiments, the design of the first clearance groove can avoid the protruding frame structure on the interactive flat panel, adapting to the situation where different brands and models of interactive flat panels may have different degrees of frame protrusion, ensuring the stable fixation of the sensor device on the interactive flat panel, avoiding displacement or detachment due to external forces such as vibration and collision, and improving the safety of the sensor device.
[0031] Optionally, the side wall of the second mounting portion is provided with a second clearance groove that communicates with the first clearance groove.
[0032] In the above embodiment, the side wall of the second mounting part is provided with a second clearance groove that communicates with the first clearance groove, which allows the structure of the clearance groove to extend to the outer shell. This is beneficial for thinning the second mounting part and makes the entire sensor device more compact and small.
[0033] Optionally, the housing further includes a third mounting portion, which has a pen slot for accommodating an electronic pen.
[0034] In the above embodiment, the sensor device housing is provided with a third mounting part with a pen slot, which is more suitable for the use scenario of interactive flat panels. Users can place the electronic pen directly in the pen slot of the sensor device housing without having to find a storage place. This convenient storage method makes the use of the electronic pen more efficient and reduces the trouble caused by users not being able to find the electronic pen. When users need to use the electronic pen, they can quickly take it out of the pen slot without performing complicated operations. This quick access method improves the user's work efficiency, especially in scenarios where the electronic pen needs to be used frequently, such as teaching and meeting recording.
[0035] On the other hand, an interactive flat panel device is provided, comprising:
[0036] Interactive flat panel;
[0037] As described above, the sensor device is magnetically attached to the interactive flat panel, with a third cover plate attached to the back shell of the interactive flat panel and a second cover plate attached to the edge of the interactive flat panel.
[0038] In this interactive whiteboard device, the sensor unit is magnetically attached to the interactive whiteboard. This installation method eliminates the need for complex mechanical connections such as bolts and screws, greatly simplifying the installation process. Users simply need to place the sensor unit near the corresponding position on the interactive whiteboard, and the magnetic force enables rapid installation, saving installation time and labor costs, making it particularly suitable for large-scale production and rapid deployment scenarios. Furthermore, due to the magnetic attachment, users can easily adjust the position of the sensor unit on the interactive whiteboard according to actual needs. This flexibility allows the interactive whiteboard device to adapt to different usage scenarios and user habits. For example, in teaching scenarios, teachers can adjust the position of the sensor unit at any time according to the teaching content and presentation requirements to achieve a better interactive effect.

[0053] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0054] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0055] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0056] Sensors play a crucial role in the technical implementation of interactive flat panels. As the device's "sensory organs," sensors can acquire real-time information about the surrounding environment or user actions, converting this information into electrical signals and transmitting them to the device's processing unit. This enables interaction between the device and the user or environment. Currently, common interactive flat panels typically integrate multiple types of sensors, such as passive infrared (PIR) sensors, which detect infrared radiation emitted by the human body and are often used in human detection and automatic control scenarios; near-field communication (NFC) sensors, enabling short-range wireless data transmission between devices; light sensors, which detect ambient light intensity and automatically adjust the device's screen brightness to adapt to different lighting environments; and proximity sensors, which detect user proximity to enable wireless interaction.
[0057] To meet the needs of different users and facilitate sensor maintenance and upgrades, some interactive whiteboards adopt an external sensor module design. This design allows the sensor module to be directly installed on the outside of the device. Compared to built-in sensors, external sensor modules offer significant advantages in terms of disassembly, assembly, and maintenance. When a sensor malfunctions or needs upgrading, users do not need to disassemble the entire interactive whiteboard; they can simply remove the external sensor module for replacement or repair, greatly reducing maintenance and time costs.
[0058] However, the existing mounting structures for external sensor modules present several problems that urgently need to be addressed. Currently, most external sensor modules are fixed to the frame of the interactive flat panel using screws. This mounting method introduces additional process complexity and cost during the production stage. Specifically, pre-drilling threaded holes in the frame of the interactive flat panel is an essential step. This not only increases the number of production steps but also requires precise control of the position and size of the threaded holes to ensure accurate installation of the sensor modules. If there are deviations in the machining of the threaded holes, the sensor modules may not be securely installed or may fail to install properly, thus affecting the overall performance and reliability of the equipment.
[0059] For users, the existing installation structure greatly limits the flexibility of sensor use, preventing them from freely adjusting the sensor's installation position according to actual needs. For example, in some application scenarios, users may want to install the sensor on different sides or specific locations of the interactive flat panel to obtain more accurate detection results or meet personalized usage habits. However, due to the screw-locking fixing method, users cannot easily achieve this requirement and can only install it according to the device's preset installation position, which to some extent reduces the user experience.
[0060] Furthermore, the existing external sensor module mounting structure is not conducive to the functional expansion of interactive flat panels. With continuous technological advancements and evolving user needs, users may wish to add new sensor modules to their existing interactive flat panels to achieve more functions. However, due to the limitations of the existing mounting structure on installation location and method, new sensor modules may not be able to be successfully installed on existing interactive flat panels, or even if they can be installed, large-scale modifications to the device are required. This not only increases costs but may also lead to stability and compatibility issues.
[0061] In summary, the existing installation structure of external sensor modules for interactive flat panels has many shortcomings in terms of production, use, and functional expansion. A new installation structure is urgently needed to solve these problems in order to improve the performance, flexibility, and scalability of interactive flat panels.
[0062] To achieve the above objectives, this application provides a sensor device that, through a built-in magnetic attachment 3, can be magnetically attached to the back shell 62 (iron alloy) of the interactive flat panel 6 during installation, thus enabling it to be externally mounted on the interactive flat panel 6. Using magnetic attachment eliminates the need for pre-drilling holes in the interactive flat panel 6, allowing users to freely adjust the installation position of the sensor device according to their needs, and easily meeting the requirement of directly installing it onto an existing interactive flat panel 6 for functional expansion.
[0063] The sensor device structure in this embodiment includes a housing 1, a circuit board 2, and a magnetic accumulator 3. The housing 1 provides an installation environment for the circuit board 2 and the magnetic accumulator 3 and provides protection for them.
[0064] Circuit board 2 is equipped with a sensor module and necessary control modules to realize the sensor function. In specific implementations, depending on the usage requirements, the sensor module can be, but is not limited to, a PIR sensor module, an NFC sensor module, a light sensor module, a distance sensor module, etc.
[0065] Specifically, the circuit board 2 includes a sensor module installed inside the housing 1 for sensing and transmitting signals; the magnetic 3 is installed inside or outside the housing 1 for adhering to the back shell 62 of the interactive flat panel 6 to install the sensor device.
[0066] The sensor device of this application embodiment exhibits significant beneficial effects in terms of ease of installation, convenient maintenance and upgrades, optimized user experience, functional expandability, and advantages in structural design and manufacturing. Specifically:
[0067] By incorporating magnetic attachment 3, the sensor is magnetically attached to the back cover 62 (iron alloy) of the interactive flat panel 6. This eliminates the complex pre-drilling process required in the production of the interactive flat panel 6, simplifying the manufacturing process and reducing production costs. During user operation, users can freely adjust the installation position of the sensor device according to their actual needs, without being limited by preset mounting holes, greatly improving flexibility and enhancing the user experience. Furthermore, when a sensor malfunctions or requires an upgrade, users can simply remove the external sensor module for replacement or repair without disassembling the entire interactive flat panel 6, significantly reducing maintenance and time costs. Additionally, with technological advancements and changing user needs, users can easily add new sensor modules to their existing interactive flat panel 6 to achieve more functions without requiring large-scale modifications to the device.
[0068] In one embodiment, the housing 1 includes an outer shell 11 and an inner shell 12. The outer shell 11 is equivalent to a housing base and has a mounting cavity, which can provide mounting space for the circuit board 2 and the magnetic component 3, etc. The outer shell 11 has an opening on at least one side that communicates with the mounting cavity inside, so as to allow the circuit board 2 and the magnetic component 3 to be installed into the mounting cavity. The inner shell 12 is equivalent to a housing cover and can be installed on the housing base to cover the mounting cavity, thereby covering and protecting the circuit board 2 and the magnetic component 3 inside.
[0069] Specifically, such as Figures 1-7 As shown, in one embodiment, the outer shell 11 includes a first mounting portion 111 and a second mounting portion 112. The first mounting portion 111 protrudes in a first direction relative to the second mounting portion 112, with the first direction pointing forward. The front side of the first mounting portion 111 is provided with a first opening 113, and the front side of the second mounting portion 112 is provided with a third opening 115. The sidewalls adjacent to the first mounting portion 111 and the second mounting portion 112 are provided with a second opening 114 communicating with the first opening 113 and the third opening 115. The inner shell 12 includes a first cover plate 121, a second cover plate 122, and a third cover plate 123 connected in a stepped manner. The first cover plate 121, the second cover plate 122, and the third cover plate 123 respectively cover the first opening 113, the second opening 114, and the third opening 115. The circuit board 2 is mounted on the first mounting portion 111, and the magnetic suction member 3 is mounted on the second mounting portion 112.
[0070] The outer casing 11 is provided with a first mounting portion 111 and a second mounting portion 112, which provide mounting space for the circuit board 2 and the magnetic component 3, respectively. The first mounting portion 111 protrudes in a first direction relative to the second mounting portion 112, making the entire outer casing 11 present an L-shaped structure. In application, the second mounting portion 112 can correspond to the back of the interactive flat panel 6, while the first mounting portion 111 can correspond to the side (i.e., the frame 61) of the interactive flat panel 6. This satisfies the purpose of adsorbing onto the back shell 62 of the interactive flat panel 6, and also allows the circuit board 2 inside the first mounting portion 111 to be placed on the side of the frame 61 of the interactive flat panel 6, making it easier for users to interact with the interactive flat panel 6 more directly through the sensor device. In addition, the opposing sides of the first mounting portion 111 and the second mounting portion 112 can also form an inner corner structure, which can be precisely locked at the corner of the back shell 62 and the frame 61 of the interactive flat panel 6, forming a more stable mounting structure.
[0071] Important, refer to Figures 3-4 In this embodiment, with the first direction pointing forward (i.e., the direction in which the first mounting part 111 protrudes relative to the second mounting part 112) as the front, a first opening 113 is provided on the front side of the first mounting part 111, a third opening 115 is provided on the front side of the second mounting part 112, and a second opening 114 is provided on the sidewall adjacent to the first mounting part 111 and the second mounting part 112 (i.e., the sidewall of the first mounting part 111 near the second mounting part 112). The three openings are connected to form a stepped, through-type opening structure. This opening structure can provide a sufficiently large operating space. When the shell 11 is processed using injection molding, only a mold core corresponding to the mounting cavity inside the shell 1 is needed, avoiding a deep and narrow demolding structure. This facilitates both rapid demolding and ensuring the quality of the finished product. When the shell 11 is processed using machining, this opening structure can also provide more room for the cutting tool to move, improving the convenience of processing. In addition, since the size of this opening structure is large enough, it can provide more ample installation space for the placement of the circuit board 2 during the assembly stage, improving the convenience of assembly.
[0072] Correspondingly, the inner shell 12 is configured with a stepped structure, including a first cover plate 121, a second cover plate 122, and a third cover plate 123, which can respectively cover the first opening 113, the second opening 114, and the third opening 115, thereby achieving complete sealing of the circuit board 2 and the magnetic component 3 installed inside the outer shell 11. Moreover, it can form the aforementioned inner corner structure that can be locked at the corner of the back shell 62 and the frame 61 of the interactive flat panel 6.
[0073] In the specific structure of the shell 1 in this embodiment, as follows: Figures 8-9As shown, in another embodiment, the outer shell 11 includes a first mounting portion 111 and a second mounting portion 112. The first mounting portion 111 protrudes in a first direction relative to the second mounting portion 112, with the first direction pointing forward. The front side of the first mounting portion 111 has a first opening 113, and the front side of the second mounting portion 112 has a third opening 115. The sidewalls adjacent to the first mounting portion 111 and the second mounting portion 112 (i.e., the sidewall of the second mounting portion 112 near the first mounting portion 111) have a second opening 114 that connects the first opening 113 and the third opening 115. The inner shell 12 includes a first cover plate 121, a second cover plate 122, and a third cover plate 123 connected in a stepped manner. The first cover plate 121, the second cover plate 122, and the third cover plate 123 respectively cover the first opening 113, the second opening 114, and the third opening 115. The circuit board 2 is mounted on the first mounting portion 111, and the magnetic suction member 3 is mounted on the second mounting portion 112.
[0074] Similarly, this embodiment can also form a large opening structure on the outer shell 11 that connects the first mounting part 111 and the second mounting part 112, which can facilitate the processing of parts, facilitate the assembly of products, and maintain the stability of the product during application.
[0075] In the structural design of the housing 1 of the sensor device, the outer shell 11 is provided with a first mounting part 111 and a second mounting part 112, which respectively provide mounting space for the circuit board 2 and the magnetic chuck 3. The inner corner structure formed by the two parts can be locked at the corner of the back shell 62 and the frame 61 of the interactive flat panel 6, forming a more stable mounting structure. The stepped through-opening structure formed on the outer shell 11 provides a larger operating space for injection molding and machining processes, which is conducive to rapid demolding, ensuring product quality, and improving assembly convenience.
[0076] In one embodiment, such as Figures 4-5 As shown, the rear wall of the inner shell 12 is provided with a first buckle 124, and the inner wall of the outer shell 11 is provided with a corresponding second buckle 118. The first buckle 124 and the second buckle 118 are engaged.
[0077] During assembly, the inner shell 12 and the outer shell 11 are first roughly aligned so that the positions of the first buckle 124 and the second buckle 118 correspond. Then, the inner shell 12 is pushed into the outer shell 11. As the inner shell 12 is pushed in further, the first buckle 124 (especially the elastic buckle) undergoes slight deformation under the action of the second buckle 118 until it slides completely into the snap-fit position of the second buckle 118. At this time, the buckle returns to its original shape, achieving a stable snap-fit.
[0078] In this embodiment, the snap-fit design of the first snap-fit 124 and the second snap-fit 118 ensures a stable connection between the inner shell 12 and the outer shell 11, effectively preventing loosening or detachment due to vibration or external force during use. The snap-fit connection simplifies the assembly process, reduces the use of screws and other fasteners, improves assembly efficiency, and prevents screw heads from being exposed on the outer surface of the product, maintaining a clean appearance and enhancing aesthetics. This improves the overall quality and competitiveness of the product, meeting market demands for high-quality, user-friendly products.
[0079] Regarding the specific design options for the first latch 124 and the second latch 118, the first latch 124 can be a latching structure that protrudes outward from the rear wall of the inner shell 12. It can be columnar, hook-shaped, or frame-shaped, etc., and the specific shape can be designed according to actual assembly requirements and space constraints. Furthermore, part of the first latch 124 has a certain degree of elasticity, allowing for slight deformation during assembly, facilitating fastening and disassembly. For ease of assembly, a guide slope is provided at the front end of the first latch 124 to guide the second latch 118 to slide smoothly into and fasten during assembly. Correspondingly, the second latch 118 can be in the form of a groove 116 or a limiting boss on the inner wall of the outer shell 11, matching the shape of the first latch 124. After fastening, it restricts the movement of the inner shell 12 in the direction of detachment from the outer shell 11.
[0080] In one embodiment, the first buckle 124 is provided on the opposite sides of the first cover plate 121 and the third cover plate 123.
[0081] In this embodiment, the inner shell 12 adopts a stepped structure, including a first cover plate 121, a second cover plate 122, and a third cover plate 123. The opposing sides of the first cover plate 121 and the third cover plate 123 (i.e., the side of the first cover plate 121 away from the second cover plate 122 and the side of the third cover plate 123 away from the second cover plate 122) are respectively provided with first latches 124. These first latches 124 cooperate with second latches 118 provided at corresponding positions on the inner wall of the outer shell 11 to achieve a stable connection between the inner shell 12 and the outer shell 11.
[0082] Specifically, by setting first buckles 124 on the opposite sides of the first cover plate 121 and the third cover plate 123, a symmetrical multi-point fixation between the inner shell 12 and the outer shell 11 is achieved. This design can disperse stress and improve the stability and reliability of the connection. Moreover, the multi-point fixation design allows the inner shell 12 to better maintain its connection with the outer shell 11 when subjected to vibration or impact, thereby enhancing the vibration resistance of the entire sensor device.
[0083] In one embodiment, such as Figure 4As shown, the inner wall of the outer shell 11 is provided with a convex rib 119 extending along the first direction, and the front end of the convex rib 119 abuts against and supports the inner shell 12.
[0084] In this embodiment, the convex ribs 119, as part of the inner wall of the outer shell 11, significantly enhance the overall structural strength of the outer shell 11. They can disperse the pressure or stress generated by the inner shell 12 on the outer shell 11, preventing the outer shell 11 from deforming or being damaged during long-term use, thereby improving the durability of the entire sensor device.
[0085] The front end of the convex rib 119 abuts against the inner shell 12 and limits the insertion depth of the inner shell 12. In conjunction with the snap-fit structure, it completely restricts the degree of freedom of movement of the inner shell 12. This design ensures the stable position of the inner shell 12 within the outer shell 11, making it less prone to shaking or loosening. This improves the structural reliability of the sensor device and helps reduce damage and malfunctions caused by vibration or external forces.
[0086] In one embodiment, the circuit board 2 is connected to a wire 21 extending outside the housing 1; wherein, a wire-locking boss 128 is provided on one edge of the rear wall of the third cover plate 123, and the wire-locking boss 128 is provided with a first wire-locking recess 1281; the side wall of the housing 11 is provided with a groove 116 corresponding to the wire-locking boss 128, and the bottom of the groove 116 is provided with a second wire-locking recess 1161, the wire-locking boss 128 is embedded in the groove 116, and the first wire-locking recess 1281 and the second wire-locking recess 1161 cooperate to lock the wire 21.
[0087] The circuit board 2 is connected to a wire 21 extending to the outside of the housing 1. This design enables the circuit board 2 to be electrically connected to external devices or power sources to meet the signal transmission and power supply requirements of the sensor device.
[0088] In the structural layout, as described above, the third cover plate 123 corresponds to the third opening 115 that covers the second mounting portion 112, and the second mounting portion 112 provides mounting space for the magnetic component 3, located on the back of the interactive flat panel 6 during application. Conversely, the first mounting portion 111 provides mounting space for the circuit board 2, located on the side of the interactive flat panel 6 during application. In this embodiment, the wire 21 is led out from the second mounting portion 112 corresponding to the third cover plate 123, that is, the wire 21 is led out from the second mounting portion 112 located on the back of the interactive flat panel 6, avoiding leading out the wire 21 from the first mounting portion 111. This satisfies the requirement of circuit interconnection while reducing the thickness of the first mounting portion 111 located on the side of the interactive flat panel 6, and can directly hide the wire 21 on the back of the interactive flat panel 6. Obviously, this optimizes the neatness of the product appearance during application and improves the user's visual perception and user experience.
[0089] A wire-clamping boss 128 is provided on one edge of the rear wall of the third cover plate 123, and a first wire-clamping recess 1281 is provided on the wire-clamping boss 128. The side wall of the outer shell 11 is provided with a groove 116 corresponding to the wire-clamping boss 128, and a second wire-clamping recess 1161 is provided at the bottom of the groove 116. When the wire-clamping boss 128 is embedded in the groove 116, the first wire-clamping recess 1281 and the second wire-clamping recess 1161 cooperate to form a wire-clamping structure for clamping the wire 21. This layout sets the fixed position of the wire 21 at the edge of the shell 1, which facilitates the wire 21 to be led out, and the wire-clamping structure fixes the wire 21, preventing the wire 21 from shaking freely inside the shell 1. Preferably, to improve reliability, a wire-clamping groove is provided at the end of the wire 21 to cooperate with the first wire-clamping recess 1281 and the second wire-clamping recess 1161, and the wire-clamping boss 128 and the side wall of the outer shell 11 are respectively clamped into the wire-clamping groove for fixation.
[0090] The design of the wire-clamping boss 128 and the groove 116 allows assemblers to intuitively see the assembly position and method. Partial assembly can be completed simply by aligning the wire-clamping boss 128 with the groove 116 and inserting it, reducing assembly difficulty. Specifically, when assembling the wire 21, simply place the wire 21 into the second wire-clamping recess 1161, then cover it with the inner shell 12 so that the wire-clamping boss 128 is embedded in the groove 116. The first wire-clamping recess 1281 naturally engages with the second wire-clamping recess 1161 to secure the wire 21, requiring no additional tools or complex operating steps, thus improving assembly efficiency.
[0091] In one embodiment, the rear wall of the third cover plate 123 is provided with a mounting recess 125, and the magnetic suction member 3 is installed in the mounting recess 125.
[0092] A mounting recess 125 is specially provided on the rear wall of the third cover plate 123. The recess is customized according to the shape, size and installation requirements of the magnetic component 3. The mounting recess 125 has a certain depth, width and shape contour, which can be precisely adapted to the magnetic component 3. For example, if the magnetic component 3 is cylindrical, the mounting recess 125 may be designed as a matching circular groove 116; if the magnetic component 3 is square, the mounting recess 125 is a square recess accordingly.
[0093] The magnetic component 3 is directly embedded in the mounting recess 125, and the two are fixed by close contact. This fixing method can be a simple physical fit, relying on the mounting recess 125 to wrap and limit the magnetic component 3 to prevent the magnetic component 3 from moving or shaking on the third cover plate 123; or it can be combined with auxiliary fixing methods such as adhesive bonding to further enhance the connection strength between the magnetic component 3 and the third cover plate 123.
[0094] In this embodiment, the mounting recess 125 provides a clear mounting position for the magnetic component 3, ensuring that the magnetic component 3 is accurately positioned on the third cover plate 123. This precise positioning helps ensure the relative positional relationship between the magnetic component 3 and other components, thereby improving the overall performance of the sensor device. Furthermore, by fixing the magnetic component 3 to the mounting recess 125, the shaking and displacement of the magnetic component 3 on the third cover plate 123 are effectively reduced. During the use of the sensor device, it may be subjected to external forces such as vibration and impact; a stable installation of the magnetic component 3 ensures that its performance is not affected.
[0095] In addition, the third cover plate 123 is a component that allows the housing 1 to be close to the back shell 62 of the interactive flat panel 6 during application. Fixing the magnetic 3 to the inner side of the third cover plate 123 allows the magnetic 3 to be closer to the interactive flat panel 6, reducing the distance between them, providing a stronger magnetic force, and improving the stability of the adsorption.
[0096] In one embodiment, the front wall of the third cover plate 123 is provided with an anti-slip pad 4.
[0097] The front wall of the third cover plate 123 is close to the surface of the interactive flat panel 6 during application. The anti-slip pad 4 installed at this position can directly contact the surface of the interactive flat panel 6, thereby effectively increasing the friction between the front wall of the third cover plate 123 and the contact surface, and preventing the sensor device from sliding or shifting during use.
[0098] In addition, during the process of installing the sensor device onto the interactive flat panel 6 and bringing it close to the surface, the anti-slip pad 4 directly contacts the interactive flat panel 6, which can prevent the hard surface of the housing 1 from directly impacting the interactive flat panel 6. The cushioning provided by the anti-slip pad 4 provides protection, avoiding damage to the interactive flat panel 6 and the sensor device, improving the reliability and durability of the sensor device, and avoiding impact noise that may cause user concerns.
[0099] Regarding the placement of the anti-slip pad 4, its shape is generally adapted to the shape and size of the front wall of the third cover plate 123. It may be a regular geometric shape, such as a circle or square, or it may be custom-designed according to the specific contours of the front wall of the third cover plate 123 to achieve a tight fit. For fixing the anti-slip pad 4, a common method is to use glue or other adhesives to attach it to the front wall of the third cover plate 123. This bonding method is simple, easy, and low-cost, providing sufficient connection strength to prevent the anti-slip pad 4 from easily falling off during normal use. Alternatively, a snap-fit structure or embedded design can be used to fix the anti-slip pad 4 to the third cover plate 123. For example, a corresponding groove or protrusion structure can be provided on the front wall of the third cover plate 123, and a matching snap-fit or groove 116 can be designed on the anti-slip pad 4. This method facilitates the disassembly and replacement of the anti-slip pad 4, making the operation more convenient when the anti-slip pad 4 is worn or needs to be replaced with an anti-slip pad 4 made of a different material.
[0100] In one embodiment, such as Figure 6 As shown, the first mounting part 111 protrudes in the first direction relative to the second mounting part 112. The inner wall of the first mounting part 111 opposite to the first cover plate 121 is provided with a first locking position 1110. The rear wall of the first cover plate 121 is provided with a second locking position 126. The two opposite edges of the circuit board 2 are respectively locked into the first locking position 1110 and the second locking position 126.
[0101] The space between the first mounting part 111 and the first cover plate 121 constitutes the assembly area of the circuit board 2. The first locking position 1110 and the second locking position 126 are located on both sides of this assembly area, providing clear boundaries and fixing points for the installation of the circuit board 2. During product assembly, the circuit board 2 can be inserted into the first mounting part 111 along the first direction and engaged with the first locking position 1110 to achieve pre-fixation of the circuit board 2. Then, the inner shell 12 is closed, and after closing, the second locking position 126 on the inner side of the inner shell 12 can be engaged with the other edge of the circuit board 2 to achieve complete fixation of the circuit board 2. In this structure, the circuit board 2 can be vertically inserted into the first mounting part 111 along the first direction, and due to the wide opening design of the Z-shaped opening on the outer shell 11, it allows the assembler to easily and accurately insert it, thus greatly shortening the assembly time. In addition, the circuit board 2 is fixed immediately after the insertion and closing work is completed, without the need for other fixing methods. Compared with traditional bolt fixing or other complex installation methods, this locking method is simpler and faster, improving production efficiency.
[0102] In addition, the circuit board 2 forms a tight fit with the first locking position 1110 and the second locking position 126. This fit not only ensures the stability of the circuit board 2 during the assembly process, but also prevents the circuit board 2 from becoming loose or shaking after assembly, thus avoiding damage to the electronic components on the circuit board 2.
[0103] During implementation, in combination Figures 1-7 The first mounting portion 111 protrudes in the first direction relative to the second mounting portion 112, and the third cover plate 123 is provided with a first clearance groove 127, which is provided along the edge where the third cover plate 123 connects to the second cover plate 122.
[0104] Specifically, the sensor device in this embodiment is mainly used in the application scenario of being installed on the side of the interactive flat panel 6, referring to... Figure 11 In the installation structure shown, in some interactive flat panels 6, the frame 61 protrudes rearward relative to the back shell 62, which hinders the adhesion between the third cover plate 123 and the back shell 62. However, the first clearance groove 127 provided on the edge of the third cover plate 123 connecting to the second cover plate 122 in this solution precisely avoids the protrusion, allowing the third cover plate 123 to fit tightly against the surface of the back shell 62, achieving a more reliable adhesion effect. This improves the adaptability of the sensor device in this embodiment.
[0105] In summary, since different brands and models of interactive flat panels 6 may have varying degrees of protrusion of the frame 61, the first recess 127 design in this solution allows the sensor device to adapt to such diverse structures. Regardless of the size of the protrusion of the frame 61 of the interactive flat panel 6, as long as it is within the accommodating range of the first recess 127, the sensor device can be installed normally and fit tightly, greatly improving the versatility and adaptability of the sensor device. Tight fit is the basis for reliable magnetic attraction. The first recess 127 ensures good contact between the third cover plate 123 and the surface of the back shell 62, reducing gaps and ensuring the stable fixation of the sensor device on the interactive flat panel 6. This prevents displacement or detachment due to external forces such as vibration and collision, improving the safety of the sensor device in use.
[0106] In another implementation, refer to Figure 8 The second mounting portion 112 protrudes in the first direction relative to the first mounting portion 111, and the second cover plate 122 is provided with a first clearance groove 127, which is provided along the edge where the second cover plate 122 connects to the first cover plate 121.
[0107] Similarly, the design of the first clearance groove 127 on the second cover plate 122 in this embodiment can also avoid the protruding structure of the frame 61 on the interactive flat panel 6, adapting to the situation where the frame 61 may protrude to different degrees on different brands and models of interactive flat panels 6, ensuring the stable fixation of the sensor device on the interactive flat panel 6, avoiding displacement or falling off due to external forces such as vibration and collision, and improving the safety of the sensor device.
[0108] In one embodiment, the side wall of the second mounting portion 112 is provided with a second clearance groove 117 that communicates with the first clearance groove 127.
[0109] The side wall of the second mounting part 112 is provided with a second relief groove 117 that communicates with the first relief groove 127, which allows the structure of the relief groove 116 to extend to the outer shell 11. This is beneficial for thinning the second mounting part 112 and making the entire sensor device more compact.
[0110] In one embodiment, such as Figure 10 As shown, the housing 1 also includes a third mounting part 13, which is provided with a pen slot 131 for accommodating the electronic pen 5.
[0111] Interactive tablets 6 are typically equipped with an electronic pen 5 to provide users with more interactive functions. In this embodiment, the sensor device housing 1 is provided with a third mounting part 13 with a pen slot 131, which is more suitable for the usage scenarios of interactive tablets 6. Users can place the electronic pen 5 directly in the pen slot 131 of the sensor device housing 1 without having to find a storage location. This convenient storage method makes the use of the electronic pen 5 more efficient and reduces the inconvenience caused by users not being able to find the electronic pen 5. When users need to use the electronic pen 5, they can quickly take it out of the pen slot 131 without complicated operations. This quick access method improves the user's work efficiency, especially in scenarios where the electronic pen 5 needs to be used frequently, such as teaching and meeting recording.
[0112] On the other hand, this embodiment also provides an interactive flat panel 6 device, including: interactive flat panel 6 and the above-mentioned sensor device, wherein the sensor device is magnetically attached to the interactive flat panel 6, the third cover plate 123 of the sensor device is attached to the back shell 62 of the interactive flat panel 6, and the second cover plate 122 is attached to the frame 61 of the interactive flat panel 6.
[0113] Similarly, based on the sensor device provided in this embodiment, the sensor device in the interactive flat panel 6 device of this embodiment is magnetically attached to the interactive flat panel 6. This installation method eliminates the need for complex mechanical connection structures, such as bolts and screws, greatly simplifying the installation process. Users only need to place the sensor device near the corresponding position on the interactive flat panel 6, and it can be quickly installed under the action of magnetism, saving installation time and labor costs, and is especially suitable for large-scale production and rapid deployment scenarios. At the same time, due to the use of magnetic attachment, users can easily adjust the position of the sensor device on the interactive flat panel 6 according to actual needs. This flexibility allows the interactive flat panel 6 device to adapt to different usage scenarios and user habits. For example, in teaching scenarios, teachers can adjust the position of the sensor device at any time according to the teaching content and display needs to obtain a better interactive effect.
