Description

Technical Field

[0001] This invention belongs to the field of teaching aids, and in particular relates to a comparative learning device for teaching marketing. Background Technology

[0002] In the existing technology, marketing teaching often requires comparative analysis of different marketing cases and strategies. To this end, various comparative learning devices have emerged. These devices usually include a support structure and a display board set on the support structure. By writing or posting relevant content on the display board, different information can be compared and displayed, which is convenient for teachers to explain and for learners to understand. However, existing comparative learning devices have significant shortcomings in use. On the one hand, after repeated use, the display boards will have writing or stains left on their surface, requiring manual wiping and cleaning. This not only increases the workload of teachers but also has low cleaning efficiency, affecting the teaching progress. On the other hand, the wiping process generates dust, which can easily spread into the air, affecting the air quality of the teaching environment. It may also be inhaled by teachers and learners, posing a potential threat to their health. In addition, the display board structure of some devices is fixed, making it impossible to flexibly switch display surfaces. When comparing multiple sets of content, the operation is cumbersome and the ease of use is poor. Summary of the Invention

[0003] The purpose of this invention is to address the significant shortcomings of existing comparative learning devices mentioned in the background art. On the one hand, after repeated use, the display board will have residual writing or stains on its surface, requiring manual wiping and cleaning. This not only increases the workload of instructors but also has low cleaning efficiency, affecting the teaching progress. On the other hand, dust is generated during the wiping process, which can easily spread into the air, affecting the air quality of the teaching environment. It may also be inhaled by instructors and learners, posing a potential threat to their health. In addition, the display board structure of some devices is fixed, making it impossible to flexibly switch display surfaces. When comparing multiple sets of content, the operation is cumbersome and the ease of use is poor. Therefore, this invention provides a comparative learning device for marketing teaching.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a comparative learning device for marketing teaching, comprising a support frame, assembly plates fixedly connected to the four corners of the back of the assembly frame, a partition plate fixedly connected to the middle of the inner wall of the support frame, inner plates symmetrically installed on the inner wall of the support frame relative to the two sides of the partition plate, and further comprising a drive assembly, a flipping outer plate, a control assembly, a wiping assembly, and a dust collection assembly, wherein the drive assembly is mounted on the partition plate, one end of the flipping outer plate is mounted on the drive assembly, the outer surface of the flipping outer plate abuts against the outer surface of the inner plate, the control assembly is mounted on the flipping outer plate, the wiping assembly is mounted on the support frame, and the dust collection assembly is mounted on the back of the support frame.

[0005] Furthermore, the driving assembly includes a support block, a driving rod, and a first driving device. The support blocks are symmetrically fixedly connected to both ends of the outer wall of the partition plate. The two ends of the driving rod are rotatably connected to the inner walls of the two support blocks. The first driving device is installed on the top of the support block, and the output end of the first driving device is fixedly connected to one end of the driving rod. One end of the flipping outer plate is fixedly connected to the outer wall of the driving rod.

[0006] Furthermore, the control component includes an abutment head, a pressure sensor, a controller, and a mounting slot. The abutment head is fixedly connected to one top end of the flip-up outer plate. The mounting slots are symmetrically opened on the top outer wall of the support frame. The pressure sensor is installed on the inner wall of the mounting slot, and the controller is installed on the back of the support frame.

[0007] Furthermore, the wiping assembly includes a guide plate, wiping pads, a guide pipe, a U-shaped seat, a take-up roller, a second drive device, and a connecting rope. Two sets of the wiping assembly are respectively mounted on the two inner plates. The two ends of the guide plate are slidably engaged with the inner walls of the partition plate and the support frame. The wiping pads are symmetrically mounted on both sides of the guide plate, with the surfaces of the two wiping pads respectively abutting the surfaces of the inner plate and the flip-out outer plate. The guide pipe is fixedly connected to the top of the support frame. The U-shaped seat is fixedly connected to the inside of the support frame. The take-up roller is rotatably connected to the inner wall of the U-shaped seat. The second drive device is mounted on the outer wall of the U-shaped seat, and its output end is fixedly connected to one end of the take-up roller. One end of the connecting rope is sleeved on the take-up roller, and the other end of the connecting rope passes through the guide pipe and the top of the support frame, and is fixedly connected to the top of the guide plate.

[0008] Furthermore, the dust collection assembly includes a dust collection box, a fan, an input pipe, a connecting pipe, a connecting hose, and a dust collection trough. The dust collection box and the fan are both fixedly connected to the back of the support frame. The input pipe connects the dust collection box and the fan. The output end of the connecting pipe is fixedly connected to the input port of the dust collection box. The dust collection troughs are symmetrically located on the inner bottom of the support frame and on both sides of the partition plate. The connecting hose connects the dust collection troughs to the connecting pipe.

[0009] Furthermore, the guide plate has a built-in counterweight.

[0010] Furthermore, a pull-out box is installed at the end of the dust collection box.

[0011] Furthermore, the first driving device, the second driving device, and the pressure sensor are all electrically connected to the controller, and the controller is electrically connected to an external power source.

[0012] Compared with existing technologies, the advantages of this comparative learning device for marketing education are: 1. This invention uses a drive component to drive the outer panel to achieve a 180-degree bidirectional rotation, which, together with the inner panel, forms multiple sets of switchable comparison display surfaces. At the same time, the control component precisely triggers the wiping component to automatically clean the writing surfaces of the outer and inner panels, realizing the integrated operation of comparison display and automatic cleaning. This solves the problems of traditional devices that require frequent manual changes of display content, low cleaning efficiency, and cumbersome operation.

[0013] 2. This invention uses the dust collection slot, connecting pipe and dust collection box of the dust collection component to collect the dust generated during wiping in real time. Combined with the filter grid and sealing treatment to prevent dust leakage, it achieves efficient dust collection and purification, thereby solving the problem of dust diffusion and pollution of the teaching environment and harm to the health of teachers and students during manual wiping.

[0016] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0017] like Figures 1-6 As shown, a comparative learning device for marketing teaching includes a support frame 1, with mounting plates 11 fixedly connected to the four corners of the back of the support frame 1, a partition plate 3 fixedly connected to the middle of the inner wall of the support frame 1, and inner plates 2 symmetrically installed on the inner wall of the support frame 1 relative to the two sides of the partition plate 3. It also includes a drive assembly 4, a flipping outer plate 5, a control assembly 6, a wiping assembly 7, and a dust collection assembly 8.

[0018] The drive assembly 4 is mounted on the partition plate 3, and one end of the flip outer plate 5 is mounted on the drive assembly 4. The outer surface of the flip outer plate 5 abuts against the outer surface of the inner plate 2.

[0019] It should be noted that the embodiment described includes a support frame 1, which is made of high-strength alloy material and has an overall rectangular frame structure. Mounting plates 11 are bolted to the four corners of the back of the support frame 1. The mounting plates 11 have waist-shaped mounting holes to accommodate different installation scenarios. A partition plate 3 is horizontally fixed to the middle of the inner wall of the support frame 1. The partition plate 3 is made of lightweight flame-retardant material and divides the interior of the support frame 1 into two independent display areas. Inner panels 2 are symmetrically installed on the inner walls of the support frame 1 relative to the two sides of the partition plate 3. The inner panels 2 are made of magnetic whiteboard material. Its edges are sealed to the inner wall of the support frame 1 via sealing strips, and the surface of the inner panel 2 is treated with anti-glare to effectively reduce the impact of reflection. It also includes a drive assembly 4, a flip outer panel 5, a control assembly 6, a wiping assembly 7, and a dust collection assembly 8. The drive assembly 4 is installed on the outer wall of the partition 3 facing the display area. The flip outer panel 5 adopts a double-sided magnetic whiteboard structure, with both sides being writable and also treated with anti-glare to maintain the same writing feel as the inner panel 2, facilitating writing and displaying content in different flip states. At the same time, an 8-12mm gap is reserved between the flip outer panel 5 and the inner panel 2. The gap is precisely designed to accommodate the wiping pad 72 in the wiping assembly 7, ensuring that the wiping pad 72 can smoothly extend between the two. The gap is neither too small, causing the wiping pad 72 to get stuck, nor too large, affecting the relative fit and stability of the flipping outer panel 5 and the inner panel 2. While ensuring the normal flipping function of the flipping outer panel 5, it provides reasonable space for subsequent automatic wiping operations. Furthermore, the flipping outer panel 5 can achieve a 180-degree bidirectional flip under the drive of the drive assembly 4.

[0020] The control component 6 is mounted on the flip-out outer panel 5, the wiping component 7 is mounted on the support frame 1, and the vacuuming component 8 is mounted on the back of the support frame 1.

[0021] It should be noted that the air intake path of the dust collection component 8 described in this embodiment corresponds precisely to the dust accumulation area inside the support frame 1, and a detachable filter grille is provided at the dust collection port, which can effectively prevent large impurities from entering the equipment and causing blockage. At the same time, the connection between the dust collection component 8 and the support frame 1 is sealed to ensure the effective use of the dust collection negative pressure.

[0022] Specifically, in the initial state of the device, the outer flip plate 5 is attached to one side of the inner plate 2 under the action of the drive assembly 4. Since the outer flip plate 5 is a double-sided writing surface and the inner plate 2 is also a writing surface, the teacher can write different marketing cases, strategies, etc. on both surfaces respectively. The two display areas separated by the partition plate 3 can be used for comparative display. When it is necessary to clean the used writing surface, the first drive device 43 in the drive assembly 4 drives the drive rod 42 to rotate, thereby enabling the outer flip plate 5 to achieve a 180-degree bidirectional flip. During the flipping process, the contact head 61 of the control assembly 6 moves with the outer flip plate 5. When the flip is in place, the contact head 61 abuts against the pressure sensor 62 on the corresponding side. The pressure signal is transmitted to the controller 63, and the controller 63 then starts the wiping assembly 7. The second drive device 76 drives the take-up roller 75 to rotate and release the connecting rope 77. The guide plate 71 slides down along the inner wall of the partition plate 3 and the support frame 1 under its own counterweight. The wiping pads 72 on both sides of the guide plate 71 just extend into the 8-12mm gap between the outer flip plate 5 and the inner plate 2. During the interval, the writing surfaces of both are wiped and cleaned simultaneously. At the same time, the fan 82 in the dust collection component 8 is activated, creating negative pressure through the dust collection groove 86, connecting hose 85, and connecting pipe 84, sucking the dust generated during wiping into the dust collection box 81. The detachable filter grille prevents larger impurities from entering, and the sealing treatment ensures effective use of negative pressure and prevents dust leakage. After cleaning, the outer panel 5 can be flipped again to fit against the inner panel 2 on the other side to form a new comparison display surface. The above operation can be repeated to achieve cyclical use. This device replaces manual cleaning with the automatic wiping action of the wiping component 7, solving the problems of large workload and low efficiency of manual cleaning in the prior art. With the timely collection of dust by the dust collection component 8, combined with the filter grille and sealing treatment, dust diffusion is effectively prevented, solving the problem of dust pollution in the teaching environment and harm to health. The 180-degree bidirectional flipping design of the outer panel 5, combined with the flexible drive of the drive component 4, makes the switching of display surfaces unnecessary and solves the problem of fixed display board structure and cumbersome operation when comparing multiple sets of content in traditional devices.

[0023] In one embodiment of the present invention, such as Figures 1-6 As shown, the drive assembly 4 includes a support block 41, a drive rod 42, and a first drive device 43. The support blocks 41 are symmetrically fixedly connected to both ends of the outer wall of the partition plate 3. The two ends of the drive rod 42 are rotatably connected to the inner walls of the two support blocks 41. The first drive device 43 is installed on the top of the support block 41, and the output end of the first drive device 43 is fixedly connected to one end of the drive rod 42. One end of the flipping outer plate 5 is fixedly connected to the outer wall of the drive rod 42.

[0024] It should be noted that the support block 41 described in this embodiment is made of high-strength cast iron and is symmetrically fixed to both ends of the outer wall of the partition plate 3 by welding. The inner wall of the support block 41 is provided with a bearing mounting groove 64, in which a high-precision deep groove ball bearing is embedded. The outer ring of the bearing is interference-fitted with the mounting groove 64, and the inner ring is clearance-fitted with the drive rod 42. The drive rod 42 is made of 45# steel and heat-treated. Its two ends are rotatably connected to the inner walls of the two support blocks 41 by bearings. The middle section of the outer wall of the drive rod 42 is provided with a flat connecting part, which is rigidly fixed to the connecting end of the flipping outer plate 5 by bolts. The connecting part is reinforced with a rib plate to improve the structure. For strength, the first drive device 43 uses a servo motor with a gearbox, which is mounted on top of one of the support blocks 41 via a motor mount. A rubber shock-absorbing pad is provided between the motor mount and the support block 41 to reduce vibration transmission during operation. The output shaft of the first drive device 43 is fixedly connected to one end of the drive rod 42 via a key connection, and an axial positioning retaining ring is added at the connection to prevent relative sliding. The other end of the drive rod 42 extends to the outside of the support block 41 and is equipped with an angle encoder, which can provide real-time feedback of the flipping angle to the controller 63 to achieve precise positioning of the flipping outer plate 5 and ensure that each flip is accurate. One end of the flipping outer plate 5 is fixedly connected to the flat connecting part of the drive rod 42 via an L-shaped connector. The surface of the connector is treated with anti-corrosion, and the connection with the flipping outer plate 5 is fixed with multi-point symmetrical bolts to ensure connection strength while avoiding deformation during flipping.

[0025] In one embodiment of the present invention, such as Figures 1-6 As shown, the control component 6 includes a contact head 61, a pressure sensor 62, a controller 63, and a mounting slot 64. The contact head 61 is fixedly connected to one end of the top of the flip-outer plate 5. The mounting slot 64 is symmetrically opened on the top outer wall of the support frame 1. The pressure sensor 62 is installed on the inner wall of the mounting slot 64. The controller 63 is installed on the back of the support frame 1.

[0026] It should be noted that the contact head 61 described in this embodiment is made of wear-resistant silicone material and has a hemispherical structure. It is fixedly connected to the top of the flip-outer plate 5 near the edge by an embedded installation. Its protrusion height is slightly higher than the surface of the flip-outer plate 5, and its position corresponds precisely to the mounting groove 64, ensuring that the flip-outer plate 5 can accurately contact the pressure sensor 62 when it is flipped into place. The mounting groove 64 is a rectangular groove symmetrically opened on the top outer wall of the support frame 1 and located on both sides of the partition plate 3. The depth of the mounting groove 64 is slightly greater than the thickness of the pressure sensor 62. The pressure sensor 62 is a high-precision strain gauge pressure sensor 62, which is fixedly installed on the bottom of the inner wall of the mounting groove 64 by waterproof adhesive. The sensor surface is covered with a dustproof film. Its signal output line is connected to the controller 63 through a pre-set wire hole inside the support frame 1, and the wire hole is filled with sealant for moisture protection. The controller 63 is an industrial-grade PLC controller 63, which is integrated into an independent protective box on the back of the support frame 1. The protective box is made of ABS. Made of flame-retardant material, the controller 63 has heat dissipation holes and a dustproof screen on its surface. In addition to connecting the pressure sensor 62, the input terminal of the controller 63 is also connected to a manual control button installed on the side of the support frame 1 and an angle encoder from the drive assembly 4. The output terminal is electrically connected to the first drive device 43, the second drive device 76 and the fan 82 respectively. It can automatically control the orderly operation of each actuator according to the trigger signal of the pressure sensor 62 and the preset program. At the same time, the controller 63 has a built-in overload protection module. When an abnormal load of the drive device or a sensor failure is detected, it can immediately cut off the power supply and issue a buzzer alarm to improve the safety of equipment operation.

[0027] In one embodiment of the present invention, such as Figures 1-6 As shown, the wiping assembly 7 includes a guide plate 71, wiping pads 72, a guide pipe 73, a U-shaped seat 74, a take-up roller 75, a second drive device 76, and a connecting rope 77. Two sets of wiping assemblies 7 are installed on two inner plates 2 respectively. The two ends of the guide plate 71 are slidably engaged with the inner walls of the partition plate 3 and the support frame 1. The wiping pads 72 are symmetrically installed on both sides of the guide plate 71, with the surfaces of the two wiping pads 72 respectively abutting against the surfaces of the inner plate 2 and the flip-out outer plate 5. The guide pipe 73 is fixedly connected to the top of the support frame 1. The U-shaped seat 74 is fixedly connected inside the support frame 1. The take-up roller 75 is rotatably connected to the inner wall of the U-shaped seat 74. The second drive device 76 is installed on the outer wall of the U-shaped seat 74, and its output end is fixedly connected to one end of the take-up roller 75. One end of the connecting rope 77 is sleeved on the take-up roller 75, and the other end of the connecting rope 77 passes through the guide pipe 73 and the top of the support frame 1, and is fixedly connected to the top of the guide plate 71.

[0028] It should be noted that the wiping assembly 7 described in this embodiment is provided in two sets, which are respectively installed in the display areas where the two inner panels 2 are located, ensuring that the cleaning operation can be completed independently on both sides. The guide plate 71 is made of lightweight alloy material, and a high-density counterweight is embedded inside to increase its weight. Sliders are symmetrically arranged at both ends. The sliders slide and engage with the slide rails preset on the inner wall of the partition plate 3 and the support frame 1. The surface of the slide rail is coated with wear-resistant grease to ensure that the guide plate 71 rises and falls smoothly without jamming. The wiping pad 72 is made of high-density sponge wrapped with wear-resistant velvet and is fastened with Velcro. The pads are attached to both sides of the guide plate 71 for easy removal and replacement. Their thickness is slightly greater than the gap between the outer flip plate 5 and the inner plate 2, ensuring close contact with both surfaces to improve wiping effectiveness. The surfaces of the two wiping pads 72 precisely contact the writing surfaces of the inner plate 2 and the outer flip plate 5, respectively. The guide tube 73 is an arc-shaped metal tube, fixedly connected to the top inner side of the support frame 1 by a bracket. Its inner wall is smoothed and polished to minimize friction when the connecting rope 77 passes through. The U-shaped seat 74 is welded from steel plates and fixedly connected to the inside of the support frame 1 by bolts. At the top, deep groove ball bearings are installed at both ends of the inner wall. The take-up roller 75 is a metal roller with spiral grooves on its surface, which is rotatably connected to the inner wall of the U-shaped seat 74 via bearings. The grooves prevent slippage or overlap of the connecting rope 77 during winding. The second drive device 76 is a stepper motor with braking function, which is mounted on the outer wall of the U-shaped seat 74 via a motor bracket. A shock-absorbing pad is installed between the motor bracket and the U-shaped seat 74, and the output end of the second drive device 76 is fixedly connected to one end of the take-up roller 75 via a flexible coupling to ensure stable power transmission and buffer instantaneous torque. The connecting rope 77... 7. High-strength nylon steel wire rope is used. One end of the rope is fixedly sleeved in the groove of the take-up roller 75 through a crimping sleeve. The other end passes through the guide pipe 73 and the wire hole at the top of the support frame 1, and is fixedly connected to the top center of the guide plate 71 by bolts. A metal lifting ring is added at the connection point to enhance the tensile strength. When the second drive device 76 rotates forward, the take-up roller 75 winds up the connecting rope 77 to drive the guide plate 71 to rise and reset. When it rotates in reverse, the connecting rope 77 is released, and the guide plate 71 descends under its own weight to complete the wiping. The braking function allows the guide plate 71 to be accurately suspended at any position.

[0029] In one embodiment of the present invention, such as Figures 1-6As shown, the dust collection assembly 8 includes a dust collection box 81, a fan 82, an input pipe 83, a connecting pipe 84, a connecting hose 85, and a dust collection trough 86. The dust collection box 81 and the fan 82 are both fixedly connected to the back of the support frame 1. An input pipe 83 is provided between the dust collection box 81 and the fan 82, and they are connected through the input pipe 83. The output end of the connecting pipe 84 is fixedly connected to the input port of the dust collection box 81. The dust collection trough 86 is symmetrically opened on the inner bottom of the support frame 1 and is located on both sides of the partition plate 3. A connecting hose 85 is provided between the dust collection trough 86 and the connecting pipe 84, and they are connected through the connecting hose 85.

[0030] It should be noted that the dust collection box 81 described in this embodiment is made of transparent acrylic material, which facilitates intuitive observation of the amount of dust accumulation inside. A drawer-type dust collection chamber is fixedly connected to its back via a snap-fit ​​structure. A silicone sealing ring is provided at the edge of the dust collection chamber to ensure airtightness. A HEPA high-efficiency filter is installed inside the dust collection box 81 near the inlet, which can effectively filter dust particles. The fan 82 is a low-noise centrifugal fan, fixedly connected to the back of the support frame 1 via a shock-absorbing bracket, located directly above the dust collection box 81. Sound-absorbing cotton is installed at the outlet of the fan 82, which can significantly reduce exhaust noise. A corrugated input pipe 83 is provided between the dust collection box 81 and the fan 82. The input pipe 83 is made of negative pressure resistant PVC material, and its two ends are fixedly connected to the outlet of the dust collection box 81 and the inlet of the fan 82 respectively via hose clamps. Sealing tape is wrapped around the connection to enhance airtightness. The connecting pipe 84 is Y-shaped. The main output end of the metal pipe is fixedly connected to the inlet of the dust collection box 81 via a flange. Two branch ends extend to the display areas on both sides of the support frame 1. The dust collection troughs 86 are elongated and symmetrically opened on the inner bottom of the support frame 1, located on both sides of the partition plate 3. Each dust collection trough 86 opening is equipped with a metal dustproof mesh to prevent larger debris from entering. An inclined air guide plate is installed inside the dust collection trough 86 to guide airflow inwards. A retractable connecting hose 85 is installed between the dust collection trough 86 and the branch end of the connecting pipe 84. The connecting hose 85 is made of wear-resistant corrugated pipe, and its two ends are fixedly connected to the outlet of the dust collection trough 86 and the branch end of the connecting pipe 84 via quick-connect fittings. The connecting hose 85 is also fixed to the inner wall of the support frame 1 with clamps to prevent shaking and wear. When the fan 82 starts, a negative pressure is formed inside the dust collection box 81, drawing dust from the dust collection trough 86 through the connecting pipe 84 and the connecting hose 85, which then passes through a HEPA filter. After being filtered by the filter screen, clean air is discharged by the fan 82, achieving efficient collection and purification of dust.

[0031] It should be understood that the guide plate 71 has a built-in counterweight, the dust collection box 81 has a pull-out box installed at the end, the first drive device 43, the second drive device 76 and the pressure sensor 62 are all electrically connected to the controller 63, and the controller 63 is electrically connected to an external power supply.

[0032] The working principle of this invention is as follows: When the device is in operation, in its initial state, the outer panel 5 flips and adheres to one side of the inner panel 2, allowing for comparative display of written content on both panels and the other side of the inner panel 2. When cleaning is required, the drive assembly 4 rotates the outer panel 5 180 degrees, triggering the corresponding pressure sensor 62 via the contact head 61. The controller 63 then activates the wiping assembly 7, causing the guide plate 71 to descend and the wiping pad 72 to clean the surfaces of the outer panel 5 and the inner panel 2. Simultaneously, the dust collection assembly sucks dust into the dust collection box 81. After cleaning, the outer panel 5 can be flipped again to form a new display surface. The wiping assembly 7 automatically cleans, solving the problems of high workload and low efficiency associated with manual cleaning. The dust collection assembly collects dust, addressing the issues of dust pollution and health hazards. The flexible flipping of the outer panel 5 eliminates the cumbersome process of switching display surfaces in traditional devices.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
