[0001] The invention relates to the technical field of teaching display equipment, in particular to a mobile display equipment based on satellite positioning teaching. Background Art

[0002] At present, mobile display equipment for teaching is a tool that is convenient for displaying teaching content flexibly in different teaching scenarios.

Whether it is a traditional classroom, laboratory, conference room or outdoor venue, the mobile display equipment can be easily moved to the required location. Teachers can use electronic whiteboards to display various teaching materials, such as PPT, pictures, videos, etc., so that students can understand the teaching content more intuitively.

[0003] After the display screen of the display equipment was raised, when the angle was adjusted for better display, the center of gravity of the display tilted forward after rotation, causing the display equipment to tip over to the side where the demonstration was being viewed, resulting in damage to the equipment and personal injury. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A mobile display device based on satellite positioning teaching, comprising:

[0006] A support mechanism, which is used to adjust the display angle and height during teaching demonstration, and is installed on the top of the base;

[0007] A display, a buffer mechanism is installed on the back of the display, and the display is connected to the supporting mechanism through the buffer mechanism;

[0008] The support mechanism comprises a side groove frame, wherein the number of the side groove frames is two and the side groove frames are symmetrically installed on the top of the base along the center position of the axis of the base, an empty groove is opened on the outer side of the side groove frame, and a cylinder is fixedly installed at the bottom of the empty groove position of the side groove frame, and a slider is slidably installed in the empty groove of the side groove frame, the bottom of the slider is connected to the output end of the cylinder, and a bending rod is installed on the inner wall of the slider, the end of the bending rod close to the slider is rotatably connected to the inner wall of the slider through a bearing, and the end of the bending rod away from the slider is bent downward, and is connected to the display through the bending rod using a buffer mechanism, when the angle of the display is adjusted, the display and the top of the buffer mechanism are tilted forward, and the positions of the display and the buffer mechanism are synchronously adjusted backward during rotation through the bending of the bending rod, so that the center of gravity of the display and the buffer mechanism are always maintained at the center position of the base, so as to avoid that after the height is adjusted, for better display, the center of gravity of the display is tilted forward after the rotation of the angle adjustment, causing the display equipment to tip to the side where the demonstration is being viewed, thereby damaging the equipment and causing personal injury.

[0009] The cam is provided with a rod groove at the outer side of the slide plate, and a screw rod is slidably installed at the rod groove of the slide plate, and one end of the screw rod is rotatably connected with the buffer mechanism through a fastener, and the other end of the screw rod passes through the rod groove of the slide plate, and the buffer mechanism is used to buffer the inertial force by utilizing the sliding friction force between the slide plate and the cross plate during buffering, thereby improving the buffer protection effect. The end of the screw rod away from the buffer mechanism is threadedly connected with a nut, and a pad is fixedly installed on the side of the nut close to the slide plate, and the side of the pad close to the slide plate is a convex arc surface at the center position and contacts with the outer side of the slide plate.

[0010] Preferably, the buffer mechanism includes a back plate, the back plate is fixedly mounted on the back of the display, and the bottom of the back plate away from the display is rotatably connected to one end of the screw rod through a fastener, a connecting plate is fixedly mounted at the center of the back plate away from the display, connecting arms are fixedly mounted at both ends of the outer side of the connecting plate, a hexagonal through groove is provided on the outer side of the connecting arm away from the connecting plate, and a hexagonal tube is slidably mounted at the hexagonal through groove of the connecting arm, the two ends of the inner wall of the hexagonal tube are fixedly connected to the end of the bending rod away from the slider, and external pressure Ring, the outer pressure ring is located at the outside of the connecting arm, and the non-opposite surfaces of the connecting arm are fixedly installed with inner pressure rings, the inner wall of the inner pressure ring is slidably adapted to the outer side of the hexagonal tube, and a buffer pad is fixedly installed between the inner pressure ring and the outer pressure ring, and the buffer pads on both sides are cooperated. When the movement is blocked, the inertial force of the display causes the buffer pad on one side to compress and deform, and the buffer pad on the other side is synchronously stretched and deformed, so that the buffer pads on both sides buffer at the same time, reducing the force on the display when it is blocked, avoiding damage to electronic components in the display, and affecting the normal display of the display. The buffer pad is made of elastic material.

[0011] Preferably, the base comprises a bottom cabinet, both sides of the top of the bottom cabinet are fixedly connected to the bottom of the side groove frame, and the center of the bottom of the bottom cabinet is fixedly installed with a support beam, both ends of the bottom of the support beam are installed with a bottom plate, both ends of the top of the bottom plate are fixedly installed with connecting fasteners, the bottom plate is fixedly connected to the bottom of the support beam through the connecting fasteners, and the bottom of the bottom plate is rotatably connected to a rotating groove plate through a rod, and a fixing block is fixedly installed at the bottom of the support beam, and the fixing block is symmetrically installed along the center position of the axis of the support beam, and rubber pads are fixedly installed on both sides of the fixing block, which cooperate with the clamping arm to prevent slipping during the moving display device. When the wheel is blocked, the resistance is transmitted to the trough plate, so that the trough plate and the bottom plate rotate relatively under the rotating connection of the rod. At the same time, during the rotation, the clamping arm on one side compresses the rubber pad, and the clamping arm on the other side moves away from the rubber pad. The resistance is buffered by the rubber elastic deformation of the rubber. At the same time, the angle between the trough plate and the obstructing object is changed, so that the angle of the force between the obstructed pulley and the obstacle is changed, which makes it easier for the pulley to pass over the obstacle at different angles. The fixed block is located on the inner side of the trough plate, and pulleys are fixedly installed on both sides of the bottom of the trough plate, and clamping arms are fixedly installed on both sides of the opposite surface of the trough plate, and the end of the clamping arm away from the trough plate is in contact with the outer side of the rubber pad.

[0012] The present invention provides a mobile display device based on satellite positioning teaching. It has the following beneficial effects:

[0013] 1. The mobile display device based on satellite positioning teaching is connected to the display by a buffer mechanism through a flex rod. When the display angle and the top of the buffer mechanism are tilted forward, the display and the buffer mechanism are synchronously adjusted backward during rotation by the flexing of the flex rod, so that the center of gravity of the display and the buffer mechanism is always maintained at the center of the base, avoiding the display device tipping to the side where the demonstration is being viewed due to the forward tilting of the center of gravity of the display after rotation for better display after the height is adjusted, resulting in damage to the equipment and personal injury.

[0014] Second, the mobile display equipment based on satellite positioning teaching can drive the display and the buffer mechanism to rotate when the connection position of the lead screw and the nut is changed through the rod groove of the slide plate, so that after the display height is adjusted, the display angle can be changed as needed for better display, which is convenient for people to watch.

[0015] 3. The mobile display equipment based on satellite positioning teaching, through the sliding connection between the slide plate and the cross plate, cooperates with the buffer mechanism, utilizes the sliding friction between the slide plate and the cross plate during buffering, and assists the buffer mechanism to buffer the inertial force, thereby improving the buffer protection effect.

[0016] 4. The mobile display device based on satellite positioning teaching cooperates through the buffer pads on both sides. When the movement is obstructed, the inertial force of the display causes the buffer pad on one side to compress and deform, and the buffer pad on the other side to stretch and deform synchronously, so that the buffer pads on both sides buffer at the same time, reducing the force on the display when it is obstructed, avoiding damage to the electronic components in the display, and affecting the normal display of the display.

[0017] 5. The mobile display equipment based on satellite positioning teaching cooperates with the rubber pad and the clamping arm. When the pulley is blocked during the mobile display equipment, the resistance is transmitted to the trough plate, so that the trough plate and the bottom plate rotate relatively under the rotation connection of the rod. At the same time, during the rotation, the clamping arm on one side compresses the rubber pad, and the clamping arm on the other side moves away from the rubber pad. The resistance is buffered by the elastic deformation of the rubber. At the same time, the angle between the trough plate and the obstructing object is changed, so that the angle of the force between the obstructed pulley and the obstacle is changed, which makes it easier for the pulley to pass over the obstacle at different angles.

DETAILED DESCRIPTION

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0029] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution: a mobile display device based on satellite positioning teaching, comprising:

[0030] A base 1, which is used to provide a support connection for the device and to perform buffering adjustment when movement is obstructed;

[0031] A support mechanism 2, which is used to adjust the display angle and height during teaching and demonstration, and the support mechanism 2 is installed on the top of the base 1;

[0032] A display 4, wherein a buffer mechanism 3 is installed on the back of the display 4, and the display 4 is connected to the support mechanism 2 through the buffer mechanism 3;

[0033] The supporting mechanism 2 includes a side slot frame 21, and the number of the side slot frames 21 is two and they are symmetrically installed on the top of the base 1 along the center position of the axis of the base 1. An empty slot is opened on the outer side of the side slot frame 21, and a cylinder 22 is fixedly installed at the bottom of the empty slot position of the side slot frame 21. When the display 4 is raised, the slider 25 is pushed by the cylinder 22 to slide in the empty slot of the side slot frame 21. When the slider 25 slides, the bending rod 26 is driven to rise. The display 4 is driven to move up through the connection between the bending rod 26 and the buffer mechanism 3 to adjust the display height. At the same time, in the process of the buffer mechanism 3 and the display 4 moving up, the screw rod 27 is driven to slide upward in the rod slot of the slide plate 24. The empty slots of the side slot frames 21 are all slidably installed with sliders 25, the bottom of the slider 25 is connected to the output end of the cylinder 22, and a bending rod 26 is installed on the inner wall of the slider 25, and the end of the bending rod 26 close to the slider 25 is rotatably connected to the inner wall of the slider 25 through a bearing. During the rotation, due to the fixed connection between the bending position of the bending rod 26 and the buffer mechanism 3, when the angle is adjusted by rotation, the bending rod 26 rotates together. Due to the bending characteristics of the bending rod 26, when the display 4 and the top of the buffer mechanism 3 tilt forward, the positions of the display 4 and the buffer mechanism 3 are synchronously adjusted backward during rotation through the bending of the bending rod 26, so that the center of gravity of the display 4 and the buffer mechanism 3 is always maintained at the center position of the base 1, and the end of the bending rod 26 away from the slider 25 is bent downward.

[0034] A cross plate 23 is fixedly installed at the bottom of the opposite surface of the side slot frame 21, and a slide plate 24 is slidably installed on the outer side of the cross plate 23. A rod groove is opened on the outer side of the slide plate 24, and a screw rod 27 is slidably installed at the rod groove of the slide plate 24. One end of the screw rod 27 is rotatably connected to the buffer mechanism 3 by a fastener, and the other end of the screw rod 27 passes through the rod groove of the slide plate 24. After the demonstration height adjustment, in order to better demonstrate, the display 4 needs to be rotated for adjustment by rotating the nut 29 to change the connection position between the nut 29 and the screw rod 27, so that the screw rod 27 drives the display 4 to rotate through the buffer mechanism 3. The outer side of the screw rod 27 is threadedly connected with a nut 29 at one end away from the buffer mechanism 3, and a pad 28 is fixedly installed on the side of the nut 29 close to the slide plate 24. The side of the pad 28 close to the slide plate 24 is a convex arc surface at the center position and contacts with the outer side of the slide plate 24.

[0035] The second embodiment is based on the first embodiment. Figure 6As shown, the buffer mechanism 3 includes a back plate 31, which is fixedly installed on the back of the display 4, and the bottom of the back plate 31 away from the display 4 is rotatably connected to one end of the screw rod 27 through a fastener, and a connecting plate 32 is fixedly installed at the center position of the back plate 31 away from the display 4. The back plate 31 is fixedly connected to the display 4 through the back plate 31, and is fixedly connected to the bending rod 26 through a hexagonal tube 34. The display 4 is connected to the support mechanism 2 by using the connecting plate 32 and the connecting arm 33. The connecting arms 33 are fixedly installed at both ends of the outer side of the connecting plate 32, and a hexagonal through groove is provided on the outer side of the connecting arm 33 away from the connecting plate 32. A hexagonal through groove is slidably installed at the hexagonal through groove of the connecting arm 33, and the two ends of the inner wall of the hexagonal tube 34 are fixedly connected to the end of the bending rod 26 away from the slider 25, and the two ends of the outer side of the hexagonal tube 34 are fixedly installed with an outer pressure ring 3 6. The outer pressure ring 36 is located on the outer side of the connecting arm 33, and the non-opposite surfaces of the connecting arm 33 are fixedly installed with the inner pressure ring 35. When the display device is moved and encounters an obstacle and the device is impacted, the inertial force of the display 4 is transmitted to the buffer pad 37 through the back plate 31, the connecting plate 32, the connecting arm 33 and the inner pressure ring 35, so that under the inertial force, the inner pressure ring 35 cooperates with the outer pressure ring 36. When the buffer pad 37 on one side is compressed, the buffer pad 37 on the other side is stretched at the same time, so that the inner pressure ring 35 and the connecting arm 33 slide on the outer side of the hexagonal tube 34, and the buffer pads 37 on both sides cooperate to buffer the inertial force. The inner wall of the inner pressure ring 35 is slidably adapted to the outer side of the hexagonal tube 34, and a buffer pad 37 is fixedly installed between the inner pressure ring 35 and the outer pressure ring 36, and the buffer pad 37 is made of elastic material.

[0036] The third embodiment is based on the first and second embodiments. Figures 7 to 9 As shown, the base 1 includes a bottom cabinet 11, and the two sides of the top of the bottom cabinet 11 are fixedly connected to the bottom of the side groove frame 21, and the center of the bottom of the bottom cabinet 11 is fixedly installed with a support beam 12, and the two ends of the bottom of the support beam 12 are installed with a bottom plate 17, and the two ends of the top of the bottom plate 17 are fixedly installed with connecting fasteners 15. When the base 1 is pushed to slide, it slides on the ground through the pulley 13. When the pulley 13 encounters obstacles during the sliding process and limits the movement of the pulley 13, the resistance is transmitted to the rotation groove plate 19 through the pulley 13, so that the rotation groove plate 19 and the bottom plate 17 rotate relative to each other under the rotation connection of the rod. The bottom plate 17 is fixedly connected to the bottom of the support beam 12 through the connecting fastener 15, and the bottom of the bottom plate 17 is rotatably connected to the rotation groove plate 19 through the rod.

[0037] A fixing block 18 is fixedly installed at the bottom of the support beam 12, and the fixing block 18 is symmetrically installed along the center position of the axis of the support beam 12, and rubber pads 14 are fixedly installed on both sides of the fixing block 18. The fixing block 18 is located on the inner side of the trough plate 19. During the rotation process, the clamping arm 16 on one side compresses the rubber pad 14, and the clamping arm 16 on the other side moves away from the rubber pad 14. The resistance is buffered by the rubber elastic deformation of the rubber pad 14, and at the same time, the angle between the trough plate 19 and the obstructing object is changed, so that the angle of the force between the obstructed pulley 13 and the obstacle is changed, so that the pulley 13 can pass over the obstacle at different angles. Pulleys 13 are fixedly installed on both sides of the bottom of the trough plate 19, and clamping arms 16 are fixedly installed on both sides of the opposite surface of the trough plate 19, and the end of the clamping arm 16 away from the trough plate 19 contacts the outer side of the rubber pad 14.

[0038] When in use, the teaching video is played and displayed through the display 4. During the display, the base 1 is pushed to slide and the position is adjusted according to the display position. At the same time, the buffer mechanism 3 and the display 4 are driven by the support mechanism 2 to adjust the height and angle during the display so that people can watch better.

[0039] When the angle and height are adjusted by the support mechanism 2, when the display 4 is raised, the slide block 25 is pushed by the cylinder 22 to slide in the empty slot of the side slot frame 21, and the bending rod 26 is driven to rise while the slide block 25 slides, and the display 4 is driven to move up through the connection between the bending rod 26 and the buffer mechanism 3 to adjust the display height. At the same time, during the upward movement of the buffer mechanism 3 and the display 4, the screw rod 27 is driven to slide upward in the rod slot of the slide plate 24. When the display height is adjusted, in order to better display, the display 4 needs to be rotated for adjustment by turning the nut 2 9. Change the connection position between the nut 29 and the screw rod 27 so that the screw rod 27 drives the display 4 to rotate through the buffer mechanism 3. At the same time, during the rotation process, due to the fixed connection between the bending position of the bending rod 26 and the buffer mechanism 3, when the angle is adjusted, the bending rod 26 rotates together. Due to the bending characteristics of the bending rod 26, when the display 4 and the top of the buffer mechanism 3 tilt forward, the bending of the bending rod 26 can adjust the position of the display 4 and the buffer mechanism 3 backward synchronously during rotation, so that the center of gravity of the display 4 and the buffer mechanism 3 is always maintained at the center position of the base 1.

[0040] In the buffer mechanism 3, the back plate 31 is fixedly connected to the display 4, and the hexagonal tube 34 is fixedly connected to the bending rod 26. The display 4 is connected to the supporting mechanism 2 by the connecting plate 32 and the connecting arm 33. When the display device is moved and encounters an obstacle, causing the device to be impacted, the inertial force of the display 4 is transmitted to the buffer pad 37 through the back plate 31, the connecting plate 32, the connecting arm 33 and the inner pressure ring 35, so that under the inertial force, the inner pressure ring 35 cooperates with the outer pressure ring 36. When the buffer pad 37 on one side is compressed, the buffer pad 37 on the other side is stretched at the same time, so that the inner pressure ring 35 and the connecting arm 33 slide on the outside of the hexagonal tube 34, and the buffer pads 37 on both sides cooperate to buffer the inertial force.

[0041] When the base 1 is pushed to slide, the pulley 13 slides on the ground. When the pulley 13 encounters obstacles during the sliding process and limits the movement of the pulley 13, the pulley 13 transmits the resistance to the trough plate 19, so that the trough plate 19 and the bottom plate 17 rotate relative to each other under the rotation connection of the rod. At the same time, during the rotation process, the clamping arm 16 on one side compresses the rubber pad 14, and the clamping arm 16 on the other side moves away from the rubber pad 14. The resistance is buffered by the rubber elastic deformation of the rubber pad 14. At the same time, the angle between the trough plate 19 and the obstructing object is changed, so that the angle of the force between the obstructed pulley 13 and the obstacle is changed, so that the pulley 13 can pass over the obstacle at different angles.

[0042] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
