Description
Technical Field
[0001] This invention relates to the field of emergency education equipment technology, specifically a mobile safety emergency education vehicle that combines education and emergency pre-positioning command. Background Technology
[0002] Currently, there is a significant contradiction between the construction of safety and emergency experience centers in my country and social needs: on the one hand, traditional fixed venues are limited by site, funding and geographical conditions, and can only cover a few central and important cities, making it difficult to reach the vast grassroots areas and remote engineering sites; on the other hand, the demand for safety and emergency knowledge among enterprise employees, community residents and other groups is becoming increasingly urgent, especially in high-risk industries such as construction, water conservancy and transportation, which require high-frequency and close-range practical training.
[0003] The current traditional mobile safety education vehicles have fixed and non-adjustable display screens, making outdoor presentations easily obstructed by obstacles and difficult to adapt to different audience viewing angles. They also make it difficult to display emergency dispatch information from a distance at disaster sites. Furthermore, they exceed height limits, making screen maintenance inconvenient and occupying boarding and aisle space. The vehicles lack expandable structures, resulting in cramped interior spaces that make it difficult to set up a full set of training equipment for multi-person centralized training. They also cannot accommodate multiple command positions, material storage, or simple first aid stations. Temporary tents need to be set up during operations, which is difficult to use in confined spaces. In addition, it is difficult to quickly set up enclosed front-line command points at disaster sites, resulting in insufficient adaptability to both peacetime and wartime scenarios. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a mobile safety emergency education vehicle that combines public education with emergency pre-positioning command, thus solving the problems mentioned in the background section.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a mobile safety emergency education vehicle that combines public education and emergency command functions, comprising a mobile vehicle, a carriage mounted on the mobile vehicle, and an electric sliding rail mounted on the carriage. The mobile safety emergency education vehicle that combines public education and emergency command functions further includes: An adjustable lifting display mechanism is installed on the vehicle body, and the adjustable lifting display mechanism is used to adjust the height of the screen as needed; A space expansion mechanism is installed on the carriage to increase the usable area of the carriage.
[0006] Preferably, the adjustable lifting display mechanism includes a lifting plate installed at the output end of the electric slide rail, a rotating plate rotatably installed on the lifting plate, and a presentation screen installed on the rotating plate. The electric slide rail is used to adjust the height of the presentation screen. The space expansion mechanism includes an expansion box mounted on the carriage, a servo motor mounted on the carriage, a pulley assembly mounted on the output end of the servo motor, a rotating rod mounted on the pulley assembly, a gear mounted on the rotating rod, and a toothed plate mounted on the expansion box. The rotating rod is rotatably connected to the carriage. When driving, it is folded down to meet road height restrictions. During maintenance, the height is lowered for easy inspection and cleaning, without occupying the boarding and aisle space, greatly improving the vehicle's adaptability to multiple scenarios. At the same time, during educational activities, it can expand the interior space of the carriage, allowing it to be folded down to meet road width restrictions when driving, and unfolded during operations to greatly increase the usable area of the carriage, providing ample space for VR training and multi-station practical teaching aids, supporting simultaneous centralized safety training for multiple people, and greatly improving training efficiency.
[0007] Preferably, the toothed plate meshes with the gear, and the expansion box contacts the carriage. During operation, the toothed plate moves the expansion box. When conducting publicity work, the display height can be flexibly adjusted according to the site environment, the target audience, and the work mode, effectively avoiding obstruction by crowds, buildings, and obstacles, expanding the outdoor visibility range, improving the effectiveness of safety education and dissemination, and taking into account the viewing perspectives of different audiences such as children and adults, thus optimizing the publicity and education experience. At the same time, in the event of an emergency, the screen can be raised to display emergency dispatch and evacuation information, realizing remote visual forward command.
[0008] Preferably, the space expansion mechanism further includes a pressure support mechanism, which includes a limiting plate mounted on the expansion box, a support plate mounted on the limiting plate by a torsion spring, a sliding block slidably mounted on the limiting plate, a sliding rod mounted on the sliding block, a hinge plate mounted on the sliding rod, and a limiting rod mounted on the hinge plate. The support plate 1 is used to support the bottom of the expansion box. The support plate 1 can be folded when not in use. During the expansion process, it can support the carriage, thereby balancing the center of gravity shift caused by unilateral expansion, increasing the overall support span of the vehicle, effectively preventing the vehicle body from tilting or overturning, protecting the chassis beam and expansion box, reducing equipment wear, and keeping the carriage, pamphlet, training and command equipment in a horizontal and stable position. This helps reduce vehicle body sway caused by personnel activities, balances the load on the carriage, avoids tire overload, and is suitable for complex field emergency sites such as mud and potholes. It takes into account structural reliability, equipment operation stability and personnel safety. During the rotation of the limit rod, it will pull the hinge plate to move, which can limit the sliding block to ensure that the support plate 1 is in a vertical state, thereby restricting the rotation of the support plate 1, improving the stability of the support plate 1 during the support process, and ensuring the structural safety of the equipment and the safety of on-site personnel.
[0009] Preferably, the pressure support mechanism further includes a hollow plate installed on the limiting plate, an elastic rod installed on the hollow plate, and an inclined block installed on the elastic rod. The inclined block has an inclined surface, and the surface of the elastic rod is provided with a spring. When the angle of the propaganda screen needs to be adjusted, the viewing angle can be adjusted according to different audiences such as children and adults, avoiding strong outdoor light reflection and improving the viewing effect of routine safety education. The limiting block will be reset by the spring on the surface of the elastic rod, thereby locking the rotation angle of the rotating plate, thus enabling multiple fixed display angles, quickly locking the optimal viewing angle, ensuring stable and unwavering image during outdoor education and emergency command, and improving the visual display effect. The pressure support mechanism further includes a hinge block slidably mounted on the lifting plate, a straight plate mounted on the hinge block by a torsion spring, an elastic rod II mounted on the hinge block by a spring, a limiting block mounted on the elastic rod II, and an inclined block II mounted on the lifting plate.
[0010] Preferably, the inclined block one is in contact with the sliding block, the inclined block one is used to limit the elastic rod one, the support plate one is rotatably connected to the limiting rod, the straight plate is rotatably connected to the rotating plate, and the limiting block is in contact with the hinge block.
[0011] Preferably, the adjustable lifting display mechanism further includes a shielding mechanism mounted on the rotating plate. The shielding mechanism includes a light-blocking plate mounted on the presentation screen, a rotating plate one mounted on the light-blocking plate, a hinge column mounted on the rotating plate one, and a rotating plate two mounted on the hinge column. The light-blocking plate serves to prevent direct sunlight from hitting the presentation screen and also protects it. During presentations, it protects the screen. When unfolded, the light-blocking plate forms a sunshade area above the screen, effectively blocking strong midday sunlight from directly hitting the screen surface. This significantly reduces mirror reflections and screen whitening caused by sunlight. Whether for outdoor safety education presentations or on-site command and dispatch information during emergencies, it ensures clear and transparent text, images, and aerial footage, with no blind spots for long-distance viewing. This significantly improves the information transmission and educational display effects in outdoor scenarios. At the same time, it blocks ultraviolet radiation, reduces the screen's operating temperature, slows down the aging of screen LEDs and circuits, and reduces equipment failures caused by high temperatures. When folded, the light-blocking plate fits snugly against the presentation screen, thus protecting it. When fully unfolded, the light-blocking plate's position is locked, improving stability during support.
[0012] Preferably, the blocking mechanism further includes a support plate II mounted on the hinge column and an L-shaped stop block mounted on the rotating plate.
[0013] Preferably, the second support plate is in contact with the L-shaped stop block, and the L-shaped stop block is used to block the second support plate.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, during public awareness campaigns, the display height can be flexibly adjusted according to the site environment, target audience, and operational mode. This effectively avoids obstruction by crowds, buildings, and obstacles, expands the outdoor visibility range, enhances the effectiveness of safety education, and accommodates different viewing angles for children and adults, optimizing the educational experience. Simultaneously, in emergency situations, the screen can be raised to display emergency dispatch and evacuation information, enabling remote, visual, and forward command. When in motion, it can be folded down to meet road height restrictions; during maintenance, the height can be lowered for easy inspection and cleaning, without occupying boarding space, significantly improving the vehicle's adaptability to various scenarios. Furthermore, during educational campaigns, the interior space of the vehicle can be expanded. When folded down while in motion, it meets road width restrictions; when unfolded during operations, it significantly increases the usable area of the vehicle. It provides ample space for VR training and multi-workstation hands-on teaching aids, supports simultaneous centralized safety training for multiple people, significantly improving training efficiency. It can be quickly switched to a multi-seat emergency forward command center to meet the needs of multi-department on-site consultation, emergency material storage, and basic first aid. It forms an integrated equipment wall-mounted surface, realizing the neat storage of various publicity and emergency equipment without the need for additional temporary sites. It is suitable for various small-scale operation scenarios in urban and rural areas, realizing the reuse of peacetime and wartime functions, and significantly reducing equipment procurement and maintenance costs. After the vehicle arrives at the accident site, the expansion box is fully deployed. The interior can be used to work through the multi-connected dispatching console, command seat, communication terminal and other tools arranged in advance on the carriage, replacing the traditional temporary tent, and quickly forming a closed, long-term office front-line command point to realize forward on-site command.
[0015] 2. In this invention, during the expansion process, the carriage can be supported, thereby balancing the center of gravity shift caused by unilateral expansion, increasing the overall vehicle support span, effectively preventing vehicle tilting and rollover, protecting the chassis beam and expansion box, reducing equipment wear, and ensuring that the carriage, presentation screen, training and command equipment maintain horizontal and stable operation. This helps reduce vehicle sway caused by personnel activities, avoids tire overload, and is suitable for complex field emergency sites such as mud and potholes. It takes into account structural reliability, equipment operation stability, and personnel operation safety. During the rotation of the limit rod, the hinge plate will be pulled to move, which can limit the sliding block to ensure that the support plate is in a vertical state, thereby restricting the rotation of the support plate and improving the stability of the support plate during the support process, ensuring the structural safety of the equipment and the safety of on-site personnel.
[0016] 3. In this invention, when the angle of the propaganda screen needs to be adjusted, the viewing angle can be adjusted according to different audiences such as children and adults, avoiding strong outdoor light reflection and improving the viewing effect of routine safety education. The limiting block will be reset by the spring on the surface of the elastic rod, thereby locking the rotation angle of the rotating plate, thus enabling multiple fixed display angles, quickly locking the optimal viewing angle, ensuring stable and unwavering image during outdoor education and emergency command, and improving the visual display effect.
[0017] 4. In this invention, the presentation screen can be protected during presentations. When the light-blocking plate unfolds outward, it forms a sunshade area above the screen, effectively blocking direct sunlight from hitting the screen surface at midday. This significantly reduces the problems of mirror reflection and screen whitening caused by sunlight. Whether for outdoor safety science popularization presentations or on-site command and dispatch information for emergencies, the text, images, and aerial footage on the screen can be kept clear and transparent, with no blind spots when viewed from a distance. This significantly improves the information transmission and educational display effect in outdoor scenarios. At the same time, it blocks ultraviolet radiation, reduces the operating temperature of the screen, delays the aging of screen LEDs and circuits, and reduces equipment failures caused by high temperatures. When folded, the light-blocking plate can fit snugly against the presentation screen, thus protecting it. When the light-blocking plate is fully unfolded, its position can be locked, improving the stability of the light-blocking plate during support. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:
[0021] Please see Figures 1-8 One embodiment of the present invention is: a mobile safety emergency education vehicle that combines education and emergency command functions, comprising a mobile vehicle 1, a carriage 2 mounted on the mobile vehicle 1, and an electric sliding rail 3 mounted on the carriage 2. The mobile safety emergency education vehicle that combines education and emergency command functions further includes: An adjustable lifting display mechanism is installed on the carriage 2. The adjustable lifting display mechanism is used to adjust the height of the screen as needed. A space expansion mechanism is installed on carriage 2 to increase the usable area of carriage 2.
[0022] The adjustable lifting display mechanism includes a lifting plate 4 installed at the output end of the electric slide rail 3, a rotating plate 5 rotatably installed on the lifting plate 4, and a presentation screen 6 installed on the rotating plate 5. The upward movement of the lifting plate 4 will drive the rotating plate 5 to move upward. The electric slide rail 3 is used to adjust the height of the presentation screen 6. The upward movement of the rotating plate 5 will drive the presentation screen 6 to move upward synchronously. The space expansion mechanism includes an expansion box 7 mounted on the carriage 2, a servo motor 8 mounted on the carriage 2, a pulley group 9 mounted on the output end of the servo motor 8, a rotating rod 10 mounted on the pulley group 9, a gear 11 mounted on the rotating rod 10, and a toothed plate 12 mounted on the expansion box 7. The rotating rod 10 is rotatably connected to the carriage 2, and the rotation of the rotating rod 10 will drive the gear 11 to rotate.
[0023] The toothed plate 12 meshes with the gear 11, the extension box 7 contacts the carriage 2, and the toothed plate 12 will drive the extension box 7 to move during operation. The rotation of the gear 11 will drive the toothed plate 12 to move to the outside of the carriage 2 through the teeth.
[0024] In this embodiment, during the presentation, the electric slide rail 3 activates, causing the lifting plate 4 to slide upwards and stop at any desired position. The upward movement of the lifting plate 4 causes the rotating plate 5 to move upwards, which in turn causes the presentation screen 6 to move upwards simultaneously. This allows for flexible adjustment of the display height based on the site environment, target audience, and operational mode, effectively avoiding obstruction from crowds, buildings, and obstacles, expanding the outdoor visibility range, improving the effectiveness of safety education, and accommodating different viewing angles for children and adults, thus optimizing the educational experience. Simultaneously, in emergency situations, the screen can be raised to display emergency dispatch and evacuation information, enabling remote, visual, and forward command. When the vehicle is in motion, it can be stored low to meet road height restrictions; during maintenance, the height can be lowered for easy inspection and cleaning, without occupying vehicle access space, significantly improving the vehicle's adaptability to various scenarios. During the presentation, the servo motor 8 activates, causing the pulley group 9 to rotate. The rotation of the pulley group 9 drives the rotating rod 10 to rotate via a belt, which in turn drives the gear 11 to rotate. The toothed plate 12 moves outward from the carriage 2 via the toothed teeth, which in turn moves the expansion box 7 outward, thus expanding the interior space of the carriage 2. When the carriage is in motion, the expansion box 12 is folded to meet road width restrictions, and when the carriage is in operation, it is unfolded to significantly increase the usable area of the carriage 2, providing ample space for VR training and multi-station practical teaching aids. It supports simultaneous centralized safety training for multiple people, greatly improving training efficiency. It can be quickly switched to a multi-seat emergency forward command center to meet the needs of multi-department on-site consultation, emergency material storage, and simple first aid. It forms an integrated equipment wall mount, realizing the neat storage of various publicity and emergency equipment without the need for additional temporary sites. It is suitable for various narrow operation scenarios in urban and rural areas, realizing the reuse of peacetime and wartime functions, and significantly reducing equipment procurement and maintenance costs. After the vehicle arrives at the accident site, the expansion box 7 is fully unfolded. The interior can be used to work through the multi-connected dispatching console, command seat, communication terminal and other tools arranged in advance on the carriage 2, replacing the traditional temporary tent, and quickly forming a closed, long-term office front-line command point to realize forward on-site command. Example 2:
[0025] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the space expansion mechanism further includes a pressure support mechanism 13. The pressure support mechanism 13 includes a limiting plate 131 mounted on the expansion box 7, a support plate 132 mounted on the limiting plate 131 by a torsion spring, the limiting plate 131 moving outward will drive the support plate 132 to move outward, a sliding block 133 slidably mounted on the limiting plate 131, a sliding rod 134 mounted on the sliding block 133, a hinge plate 135 mounted on the sliding rod 134, and a limiting rod 136 mounted on the hinge plate 135, the support plate 132 driving the limiting rod 136 to rotate. Among them, the support plate 132 is used to support the bottom of the expansion box 7. The support plate 132 will rotate downward through the torsion spring. The support plate 132 can be folded when not in use.
[0026] The pressure support mechanism 13 also includes a hollow plate 137 installed on the limiting plate 131, an elastic rod 138 installed on the hollow plate 137, and an inclined block 139 installed on the elastic rod 138. The elastic rod 138 will move through the spring on its surface and drive the inclined block 139 to reset. The inclined block 139 has an inclined surface, and the surface of the elastic rod 138 is provided with a spring. The pressure support mechanism 13 also includes a hinge block 1310 slidably mounted on the lifting plate 4, a straight plate 1311 mounted on the hinge block 1310 by a torsion spring, an elastic rod 1312 mounted on the hinge block 1310 by a spring, a limiting block 1313 mounted on the elastic rod 1312, and an inclined block 1314 mounted on the lifting plate 4. The rotation of the elastic rod 1312 will drive the rotating plate 5 to rotate.
[0027] The inclined block 139 and the sliding block 133 are in contact with each other. The inclined block 139 is used to limit the elastic rod 138. The support plate 132 is rotatably connected to the limiting rod 136. The straight plate 1311 is rotatably connected to the rotating plate 5. During the movement of the limiting block 1313, the spring set on the surface of the elastic rod 1312 will be compressed. The limiting block 1313 and the hinge block 1310 are in contact with each other.
[0028] In this embodiment, during the expansion process, the outward movement of the expansion box 7 causes the limiting plate 131 to move outward, which in turn causes the support plate 132 to move outward. When the support plate 132 leaves the interior of the carriage 2, it rotates downward via a torsion spring. Subsequently, the support plate 132 drives the limiting rod 136 to rotate, thereby supporting the carriage 2. This balances the center of gravity shift caused by unilateral expansion, increases the overall vehicle support span, effectively prevents vehicle tilting and rollover, protects the chassis beam and expansion box 7, and reduces equipment wear. Simultaneously, it keeps the carriage 2, the presentation screen 6, and the training and command equipment in a horizontal and stable position, reducing vehicle sway caused by personnel movement and minimizing the load on the carriage 2, preventing excessive tire wear. This device is designed for use in complex outdoor emergency environments, including muddy terrain and uneven surfaces. It balances structural reliability, equipment operational stability, and personnel safety. During rotation, the limit rod 136 pulls the hinge plate 135, which in turn pulls the sliding rod 134. The sliding rod 134 then pulls the sliding block 133, which in turn moves the sliding block 133. During this movement, the sliding block 133 contacts the inclined block 139, generating a compressive force. The movement of the inclined block 139 causes the elastic rod 138 to move synchronously. Once the sliding block 133 has passed the inclined block 139, the elastic rod 138 moves via a surface spring, causing the inclined block 139 to reset. This effectively limits the movement of the sliding block 133. The support plate 132 is in a vertical position, thus restricting its rotation and improving its stability during support, ensuring the safety of the equipment structure and on-site personnel. When the angle of the presentation screen 6 needs to be adjusted, the staff pulls the straight plate 1311 to rotate it, which in turn drives the elastic rod 1312 to rotate. The rotation of the elastic rod 1312 drives the rotating plate 5 to rotate, which in turn drives the presentation screen 6 to rotate and adjust the angle. This allows for adjustment of the viewing angle according to different audiences such as children and adults, avoiding glare from strong outdoor light and improving the viewing effect of routine safety education. The movement of the straight plate 1311 drives the hinge block 1310 to move, and then the hinge block 1310 drives the elastic rod 1312 to move. When elastic rod 1312 moves, it causes limiting block 1313 to move downward. During the downward movement of limiting block 1313, it will contact inclined block 1314 and exert a squeezing force on limiting block 1313 through the inclined surface, forcing limiting block 1313 to drive elastic rod 1312 to move. At the same time, during the movement of limiting block 1313, it will compress the spring set on the surface of elastic rod 1312. When limiting block 1313 passes inclined block 1314, limiting block 1313 will be reset by the spring on the surface of elastic rod 1312, thereby locking the rotation angle of rotating plate 5. This allows for multiple fixed display angles, quickly locking the optimal viewing angle, ensuring stable and unwavering images during outdoor education and emergency command, and improving the visual display effect. Example 3:
[0029] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the adjustable lifting display mechanism further includes a shielding mechanism 14 mounted on the rotating plate 5. The shielding mechanism 14 includes a light-blocking plate 141 mounted on the presentation screen 6, a rotating plate 142 mounted on the light-blocking plate 141, a hinge column 143 mounted on the rotating plate 142, and a rotating plate 144 mounted on the hinge column 143. The upward movement of the hinge column 143 will push the rotating plate 142 and exert a squeezing force on the rotating plate 144. Among them, the light-blocking plate 141 is used to prevent direct sunlight from shining on the propaganda screen 6 and to protect it, and the rotating plate 142 can unfold and lift the light-blocking plate 141.
[0030] The shielding mechanism 14 also includes a second support plate 145 mounted on the hinge column 143 and an L-shaped stop block 146 mounted on the rotating plate 5. The second support plate 145 can support the hinge column 143 and the light-blocking plate 141. The second support plate 145 and the L-shaped stop block 146 are in contact with each other, and the L-shaped stop block 146 is used to block the second support plate 145.
[0031] In this embodiment, during a presentation, staff push the support plate 145 to apply pressure to the hinge column 143, causing it to move upwards. This upward movement pushes the rotating plate 142 and applies pressure to the rotating plate 144, allowing the rotating plate 142 to unfold and lift the light-blocking plate 141, thus protecting the presentation screen 6. The unfolded light-blocking plate 141 forms a sunshade area above the screen, effectively blocking direct sunlight from reaching the screen surface and significantly reducing glare and screen whitening caused by sunlight. Whether for outdoor safety education presentations or for on-site command and control of emergency situations, the text on the screen remains clear. The images and aerial footage are clear and transparent, with no blind spots when viewed from a distance, significantly improving the information transmission and educational display effects in outdoor scenarios. At the same time, it blocks ultraviolet rays, reduces the operating temperature of the screen, delays the aging of screen LEDs and circuits, and reduces equipment failures caused by high temperatures. When folded, the light-blocking plate 141 can fit against the presentation screen 6, thus protecting the presentation screen 6. When the light-blocking plate 141 is fully unfolded, by locking the second support plate 145 on the top of the L-shaped block 146, the second support plate 145 can support the hinge column 143 and the light-blocking plate 141, thereby locking the position of the light-blocking plate 141 and improving the stability of the light-blocking plate 141 during the support process.
