Description

Technical Field

[0001] This utility model relates to the field of teaching aids technology, and in particular to an interactive whiteboard teaching device. Background Technology

[0002] With the deepening of digital teaching reform, the need for traditional teaching tools to adapt to visualization, real-time teacher-student interaction, and integration of teaching resources is becoming increasingly prominent. Therefore, interactive whiteboard teaching equipment is set up to provide an intuitive knowledge presentation carrier for classroom teaching, support real-time interactive communication between teachers and students and among students, and assist in the efficient delivery and in-depth explanation of teaching content.

[0003] A search revealed Chinese Patent Publication No. CN222690234U, which discloses an interactive whiteboard teaching device. Addressing the issue that existing whiteboards are typically made of metal, allowing only writing instruction and resulting in a limited learning experience and poor interaction with viewers, this invention proposes the following solution: It includes an I-shaped base with two guide sleeves fixedly connected to one side. Each guide sleeve contains a sliding rod, and a whiteboard is fixedly connected between one side of each sliding rod. A first guide rail is fixedly connected to the top of the two sliding rods, and a first slider is slidably connected to the top of the first guide rail. In this invention, staff can use a projector and whiteboard for teaching, while simultaneously recording the process with a camera, enhancing the interaction between the device and the user. It is easy to use, and when the whiteboard is raised, a pull-out rod provides support, increasing the device's stability during use.

[0004] The aforementioned patents have the following shortcomings: Since most existing devices adopt an integrated rigid structure, the overall size of the equipment is large, requiring a large space for storage. They are difficult to place flexibly during transportation and are easily damaged by collisions. When moving the equipment in the classroom or setting up temporary teaching scenarios, the operation is cumbersome and time-consuming, which limits the flexible application of the equipment in multi-scenario teaching.

[0005] Therefore, an interactive whiteboard teaching device is proposed. Utility Model Content

[0006] In view of this, the present invention aims to provide an interactive whiteboard teaching device to solve or alleviate the technical problems existing in the prior art, or at least provide a beneficial alternative.

[0007] The technical solution of this utility model embodiment is implemented as follows: An interactive whiteboard teaching device includes a reinforcing frame, and further includes:

[0008] The whiteboard body is fixed to one side of the reinforcing frame. Support frames are provided on both sides of the reinforcing frame. A projector is installed on one side of the top of the reinforcing frame, and a camera is fixed to the bottom of the projector.

[0009] A folding structure is provided at both ends of a reinforcing frame. The folding structure includes a rotating seat fixed at both ends of the reinforcing frame. One end of the rotating seat is rotatably connected to a connecting plate. A locking component is provided on one side of the reinforcing frame.

[0010] A storage structure for moving the projector is located at the top of the reinforced frame;

[0011] The flip structure used to adjust the angle of the whiteboard body is located on one side of the support frame.

[0012] In some embodiments: self-locking casters are fixed on both sides of the bottom end of the support frame, and a counterweight is fixed on the top side of the support frame away from the reinforcing frame.

[0013] In some embodiments: the locking assembly includes a rotating frame fixed to one side of one set of reinforcing frames, a fixing frame fixed to one side of another set of reinforcing frames, a guide rod rotatably connected inside the rotating frame via a pin, and a pressing frame slidably connected to the outside of the guide rod, and a compression spring connected to the guide rod fixed inside the pressing frame.

[0014] In some embodiments: the guide rod forms a telescopic structure with the pressing frame via a compression spring, and the rotating seats are symmetrically distributed on the vertical center line of the connecting plate.

[0015] In some embodiments: the flipping structure includes a rotating shaft fixed to the side of the reinforcing frame near the support frame, a roller bearing is sleeved on the outer side of the rotating shaft, a worm gear is fixed to the end of the rotating shaft away from the reinforcing frame, a protective sleeve fixedly connected to the support frame is sleeved on the outer side of the worm gear, a worm is rotatably connected to the top of the protective sleeve, and a crank handle is fixed to one side of the worm.

[0016] In some embodiments: the rotating end of the worm extends to the outside of the protective sleeve and is connected to the crank handle, and the rotating shaft forms a rotating structure with the support frame through a roller bearing.

[0017] In some embodiments: the storage structure includes a second fixed frame fixed to one side of the top of the reinforcing frame, a movable frame rotatably connected to the top of the second fixed frame, a damping rotating frame connected to the damping rotation of the projector fixed to one side of the bottom of the movable frame, a first fixed frame fixed to the other side of the top of the reinforcing frame, and an electric telescopic rod rotatably connected to the top of the first fixed frame.

[0018] In some embodiments: the telescopic end of the electric telescopic rod is rotatably connected to the movable frame, and the second fixed frame and the reinforcing frame are welded together as an integral structure.

[0019] The present invention has the following advantages due to the adoption of the above technical solution:

[0020] 1. An interactive whiteboard teaching device, which separates the pressing frame from the fixed frame by pulling it, releasing the locking engagement between the pressing frame and the fixed frame, and causes the two whiteboard bodies to fold inward by rotating the rotating seat around the connecting plate. This realizes the folding function of the whiteboard surface of the device. After folding, the whiteboard surface folds inward, effectively reducing the overall space occupied and reducing the space storage and transportation costs. At the same time, the inward-facing whiteboard surface can avoid direct contact with external hard objects and dust, reducing scratches, contamination and other damage.

[0033] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature 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 directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] Example 1:

[0037] like Figures 1 to 6 As shown, an interactive whiteboard teaching device includes a reinforcing frame 1, and also includes:

[0038] The whiteboard body 3 is fixed to one side of the reinforcing frame 1. Support frames 5 are provided on both sides of the reinforcing frame 1. A projector 8 is installed on one side of the top of the reinforcing frame 1. A camera 9 is fixed at the bottom of the projector 8.

[0039] Folding structure 2 is provided at both ends of the reinforcing frame 1. Folding structure 2 includes a rotating seat 201 fixed at both ends of the reinforcing frame 1. One end of the rotating seat 201 is rotatably connected to a connecting plate 202. A locking component is provided on one side of the reinforcing frame 1.

[0040] The storage structure 7 for moving the projector 8 is located at the top of the reinforcing frame 1;

[0041] The flip structure 6, used to adjust the angle of the whiteboard body 3, is set on one side of the support frame 5.

[0042] like Figures 1 to 4 As shown: self-locking casters 10 are fixed on both sides of the bottom end of the support frame 5, and a counterweight 4 is fixed on the top side of the support frame 5 away from the reinforcing frame 1.

[0043] In this embodiment, the device can be moved to the designated teaching position by the self-locking casters 10, while the counterweight 4 plays a balancing and stabilizing role on the support frame 5 to prevent it from tipping over. The whiteboard body 3 serves as a teaching display and interactive carrier, the projector 8 projects the teaching content onto the surface of the whiteboard body 3, and the camera 9 captures the writing content and interactive operations on the whiteboard body 3 in real time.

[0044] like Figures 1 to 4 As shown, the locking assembly includes a rotating frame 206 fixed to one side of one set of reinforcing frames 1, and a fixing frame 207 fixed to one side of another set of reinforcing frames 1. The rotating frame 206 is rotatably connected to a guide rod 204 via a pin, and a pressing frame 203 is slidably connected to the outside of the guide rod 204. A compression spring 205 connected to the guide rod 204 is fixed inside the pressing frame 203. The guide rod 204 and the pressing frame 203 form a telescopic structure through the compression spring 205. The rotating seats 201 are symmetrically distributed on the vertical center line of the connecting plate 202.

[0045] In this embodiment, when the equipment needs to be stored or transported, the pressing frame 203 is pulled to separate from the fixed frame 207. At the same time, the pressing frame 203 is pulled to one side to make the guide rod 204 rotate around the rotating frame 206, thereby releasing the locking engagement between the pressing frame 203 and the fixed frame 207. At this time, the whiteboard body 3 can be pushed to drive the rotating seat 201 to rotate around the connecting plate 202, so that the whiteboard body 3 at both ends of the reinforcing frame 1 is folded inward, which greatly reduces the overall volume of the equipment and reduces the storage space occupation and transportation difficulty to a certain extent. At the same time, the way the board surface is folded inward avoids the surface of the whiteboard body 3 from contacting hard objects outside, which reduces the scratches and dust contamination on the board surface to a certain extent.

[0046] Example 2:

[0047] An interactive whiteboard teaching device, this embodiment is based on embodiment 1 with the following improvements, such as... Figures 1 to 5 As shown, the flipping structure 6 includes a rotating shaft 601 fixed to the side of the reinforcing frame 1 near the support frame 5. A roller bearing 606 is sleeved on the outer side of the rotating shaft 601. A worm gear 605 is fixed to the end of the rotating shaft 601 away from the reinforcing frame 1. A protective sleeve 603 fixedly connected to the support frame 5 is sleeved on the outer side of the worm gear 605. A worm 604 is rotatably connected to the top of the protective sleeve 603. A crank 602 is fixed to one side of the worm 604. The rotating end of the worm 604 extends to the outer side of the protective sleeve 603 and is connected to the crank 602. The rotating shaft 601 forms a rotating structure with the support frame 5 through the roller bearing 606.

[0048] In this embodiment, when it is necessary to adjust the viewing angle of the whiteboard body 3, the worm gear 604 is rotated by turning the crank handle 602. At the same time, the worm gear 604 meshes with the worm wheel 605 and drives the rotating shaft 601 to rotate. Simultaneously, the rotating shaft 601 drives the reinforcing frame 1 and the whiteboard body 3 to adjust their angles, so that the surface of the whiteboard body 3 avoids the direction of light reflection, thus avoiding the glare phenomenon to a certain extent.

[0049] like Figures 1 to 6 As shown, the storage structure 7 includes a second fixed frame 704 fixed to one side of the top of the reinforcing frame 1. The top of the second fixed frame 704 is rotatably connected to a movable frame 701. One side of the bottom of the movable frame 701 is fixed to a damping rotating frame 705 that is damped and rotatably connected to the projector 8. The other side of the top of the reinforcing frame 1 is fixed to a first fixed frame 703. The top of the first fixed frame 703 is rotatably connected to an electric telescopic rod 702. The telescopic end of the electric telescopic rod 702 is rotatably connected to the movable frame 701. The second fixed frame 704 and the reinforcing frame 1 are welded together as an integrated structure.

[0050] In this embodiment, when the projector 8 is not needed, the electric telescopic rod 702 is activated to retract and pull the movable frame 701 to rotate around the second fixed frame 704. At the same time, the movable frame 701 drives the damped rotating frame 705 and the projector 8 to move towards the top of the reinforced frame 1, so that the projector 8 is stored in the preset position at the top of the reinforced frame 1, reducing the overall space occupied by the equipment and avoiding damage to the projector 8 caused by collisions with external hard objects.

[0051] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
