Description

Technical Field

[0001] This invention relates to the field of fire safety publicity equipment technology, specifically a fire emergency publicity officer's carrying bag with exoskeleton assistance. Background Technology

[0002] Fire emergency publicity requires staff to go into various complex scenarios to carry out popularization, hazard investigation, and distribution of materials. During the operation, they need to carry a variety of materials such as publicity materials, electromechanical equipment, and emergency tools. The usual load can reach 20-30kg, and most of the work is done on foot for a long time, which places high demands on the load-bearing capacity and ease of use of the equipment.

[0003] Existing fire safety publicity backpacks only have basic storage functions and lack professional mechanical support structures. The entire weight is concentrated on the shoulders, neck, and lower back, which can easily lead to occupational injuries such as muscle fatigue, back strain, and spinal deformities during long-term use, significantly reducing the ability of personnel to work continuously.

[0004] Fire safety awareness campaigns are often conducted in areas inaccessible by vehicles, such as alleyways and buildings, requiring manual carrying of heavy loads. Conventional backpacks lack external support, restricting movement and causing instability under load, resulting in low safety and efficiency. Existing exoskeleton-based load-bearing solutions typically fix the backpack entirely to the exoskeleton frame, resulting in a tight fit with no room for movement. This makes accessing supplies difficult and cumbersome, significantly diminishing the auxiliary value of exoskeletons. Summary of the Invention

[0005] To address the shortcomings of existing technologies and solve the problems mentioned above, such as the lack of external support in conventional backpacks, which restrict human movement and cause instability under load, resulting in low operational safety and efficiency, and the fact that existing load-bearing solutions with exoskeletons often fix the backpack entirely to the exoskeleton frame, making it inconvenient to access materials and cumbersome to operate during operations, thus greatly reducing the auxiliary value of exoskeletons, this invention proposes a fire emergency publicity officer carrying bag with exoskeleton assistance.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fire emergency publicity officer carrying bag with exoskeleton assistance, comprising a back panel of a lower limb exoskeleton and fire safety publicity equipment.

[0043] The technical solution of the present invention will now be clearly and completely described 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.

[0044] Example 1, please refer to the appendix. Figure 1 - Appendix Figure 2 This invention provides a fire emergency publicity personnel carrying bag with exoskeleton assistance, including a back plate 1 of a lower limb exoskeleton and fire publicity equipment 2. A support frame 3 is fixedly provided on the rear side of the back plate 1, and a circular bearing ring 4 is rotatably connected to the surface of the support frame 3. The equipment 2 includes a backpack 201, which is detachably mounted on the bearing ring 4 via a connecting component 5. The bearing ring 4 includes a set of semi-circular arc frame one 41 and two sets of quarter-circular arc frame two 42. One end of each of the two arc frame two 42 is hinged to one end of the arc frame one 41, and the other end of the two arc frame two 42 is connected by a detachable component 8. The detachable component 8 can be connected by a buckle, a pin, or a bolt, etc. In this embodiment, a buckle connection is used for easy assembly and disassembly.

[0045] Specifically, by installing the backpack 201 on the load-bearing ring 4, its weight is distributed to the back plate 1 of the lower limb exoskeleton. Thus, the exoskeleton bears the weight of the backpack 201, which bears and distributes the load, effectively reducing pressure on the shoulders, neck, waist and back, preventing strain, and significantly improving the ability to carry heavy loads for long periods of time. When the backpack 201 needs to be used, the backpack 201 can be rotated from the back to the front of the exoskeleton by rotating the load-bearing ring 4, which makes it convenient for the promoter to use the backpack 201. The materials in the backpack 201 can be easily put in and taken out without disassembling it. The two rotatable arc-shaped frames 42 can open the load-bearing ring 4 when wearing the exoskeleton, making it convenient for the promoter to enter.

[0046] Example 2, please refer to the appendix. Figure 3 - Appendix Figure 4 In conjunction with Embodiment 1, a fixing frame 6 is fixedly provided on the rear side of the back plate 1. A plug-in assembly 7 is installed on the surface of the fixing frame 6. The plug-in assembly 7 includes an electric push cylinder 701 and a plug hole 703. The electric push cylinder 701 is fixedly provided on the fixing frame 6. An elastic telescopic plug rod 702 is fixedly provided at the drive end of the electric push cylinder 701. The plug hole 703 is opened at the bottom of the bearing ring 4. The elastic telescopic plug rod 702 is plugged into the plug hole 703. The elastic telescopic plug rod 702 includes an outer cylinder and an inner rod that are slidably connected. An elastic element is provided inside the outer cylinder to push the inner rod out. A controller is provided on the front side of the bearing ring 4 to control the extension and retraction of the electric push cylinder 701. The promoter controls the electric push cylinder 701 by pressing the controller.

[0047] Specifically, by extending the electric push cylinder 701, the elastic telescopic rod 702 is inserted into the insertion hole 703 while in a retracted state, thus limiting the bearing ring 4. This allows the bearing ring 4 to rotate while the promoter is walking or running. When it is necessary to rotate the bearing ring 4, the electric push cylinder 701 retracts, causing the elastic telescopic rod 702 to exit the insertion hole 703, thereby releasing the fixation of the bearing ring 4.

[0048] Please see the appendix Figure 4 Trapezoidal limiting plates 704 are respectively provided on both sides of the insertion hole 703. A second fixing frame 705 is provided on one side of the limiting plate 704. The second fixing frame 705 is slidably connected to the limiting plate 704, and an elastic telescopic rod 706 is fixed between the second fixing frame 705 and the limiting plate 704. The elastic telescopic rod 706 includes an outer cylinder and an inner rod that are slidably connected. An elastic element is provided inside the outer cylinder to push the inner rod out.

[0049] Specifically, the limiting plate 704 slides out and remains on both sides of the insertion hole 703 by the elastic force of the elastic telescopic rod 706, so that when the elastic telescopic rod 702 is between the two limiting plates 704, it is directly below the insertion hole 703. When the backpack 201 is finished using and the bearing ring 4 needs to be fixed again, the electric push cylinder 701 extends and pushes the elastic telescopic rod 702 to press against the bearing ring 4 again. At this time, the promoter drives the bearing ring 4 to rotate. Since the bearing ring 4 rotates clockwise or counterclockwise, one of the two limiting plates 704 is always in front and the other in the back. When the elastic telescopic rod 702 presses against the front limiting plate 704, the elastic telescopic rod 702 moves along the limiting plate 706. 4. The inclined plane pushes the limiting plate 704 to slide outward, so that the elastic telescopic rod 702 passes through the limiting plate 704 and abuts against the plane of the rear limiting plate 704, thereby limiting the rotation angle of the elastic telescopic rod 702 and the bearing ring 4, so that the elastic telescopic rod 702 is stably positioned below the insertion hole 703, achieving rapid docking. Thus, whether the bearing ring 4 rotates clockwise or counterclockwise, the rear limiting plate 704 limits the elastic telescopic rod 702, so that when the bearing ring 4 cannot rotate, the elastic telescopic rod 702 can automatically insert into the insertion hole 703, achieving rapid and accurate docking of the elastic telescopic rod 702 and the insertion hole 703 without manual alignment.

[0050] Example 3, please refer to the appendix. Figure 5 In conjunction with Embodiment 1, the inner side of the bearing ring 4 is provided with a toothed groove, the surface of the support frame 3 is fixed with a motor 9, the drive end of the motor 9 is fixed with a gear 10, and the gear 10 is meshed with the toothed groove for transmission. A controller is provided on the bearing ring 4 to control the rotation of the motor 9. The promoter controls the rotation of the motor 9 by pressing the controller and adjusts the rotation angle of the bearing ring 4. Embodiments 2 and 3 can also be used in combination.

[0051] Specifically, the motor 9 drives the gear 10 to rotate, and the gear 10 drives the bearing ring 4 to rotate through the cooperation of the tooth groove. The bearing ring 4 can be rotated electrically, and the backpack 201 can be turned from the back to the front with one click without taking it off, turning around or bending over, and the device 2 can be quickly picked up and put on.

[0052] Example 4, please refer to the appendix. Figure 6 - Appendix Figure 7 The connecting component 5 includes an upper hook 501, a lower hook 502, and a connecting strap 503. The upper hook 501 and the lower hook 502 are respectively installed on the outer side wall of the bearing ring 4 from top to bottom. The connecting strap 503 is fixed on the backpack 201. The upper and lower ends of the connecting strap 503 are respectively provided with extension layers, and the extension layers are provided with connection ports 504.

[0053] Specifically, when installing backpack 201, the upper hook 501 and the lower hook 502 are hooked onto the connecting ports 504 on the upper and lower sides of the connecting strap 503, respectively, so that backpack 201 can be installed on the bearing ring 4.

[0054] Please see the appendix Figure 7 - Appendix Figure 8 The connecting assembly 5 also includes a slide groove 506, an electric cylinder 515, and a mounting plate 513. The slide groove 506 is located on the rear side of the bearing ring 4. The side wall of the slide groove 506 has a moving opening. An L-shaped mounting plate 507 is vertically slidably connected to the side wall of the slide groove 506. The lower hook 502 is fixed on the mounting plate 507. The electric cylinder 515 is vertically fixed on the rear side of the support frame 3. The two sides of the mounting plate 507 are respectively provided with snap-fit ​​components 508. The mounting plate 513 is installed on the rear top of the bearing ring 4. The upper hook 501 is fixedly installed on the side wall of the mounting plate 513. A tension spring 509 is fixed between the mounting plate 507 and the slide groove 506.

[0055] Specifically, tension spring 2 509 applies an upward pulling force to mounting plate 1 507, while electric cylinder 2 515 extends and presses down on mounting plate 1 507, thereby adjusting the distance between upper hook 501 and lower hook 502. When the distance between upper hook 501 and lower hook 502 is the smallest, it is convenient to pass the connecting port 504 through the two hooks. When the distance between upper hook 501 and lower hook 502 is the largest, the connecting strap 503 can be pulled down to keep it taut, thereby preventing the backpack 201 from shaking and falling off when the promoter runs violently.

[0056] Please see the appendix Figure 7 - Appendix Figure 8The snap-fit ​​assembly 508 includes a second sliding groove 5081 and a snap-fit ​​slot 5084. The second sliding groove 5081 is formed on the surface of the first mounting plate 507, and a snap-fit ​​block 5082 is slidably connected inside the second sliding groove 5081. An elastic element 5083 is fixed between the snap-fit ​​block 5082 and the second sliding groove 5081. The elastic element 5083 can be a leaf spring, a coil spring, a torsion bar spring, a rubber spring, etc., preferably a coil spring. The snap-fit ​​slot 5084 is formed on the lower side wall of the first sliding groove 506. The interior of the slot 5084 has a through-hole. At the bottom of the support frame 3, corresponding to the through-hole, an electric push cylinder 3 5085 is fixed. Electric push cylinder 2 515 and electric push cylinder 3 5085 are electrically connected to a controller. The controller is installed on the back plate 1. The back plate 1 has a built-in battery module for powering electric push cylinder 2 515, electric push cylinder 3 5085 and the exoskeleton. Electric push cylinder 2 515 and electric push cylinder 3 5085 are installed below the support frame 3 and do not need to rotate with the bearing ring 4.

[0057] Specifically, the locking block 5082 slides out of the second slide groove 5081 by the elastic force of the elastic element 5083 and abuts against the inner wall of the first slide groove 506. When the first mounting plate 507 slides to the bottom, the locking block 5082 inserts into the locking groove 5084 to fix the first mounting plate 507, so that the distance between the upper locking hook 501 and the lower locking hook 502 is kept to the maximum, so as to prevent the electric push cylinder 515 from being misaligned with the first mounting plate 507 when the bearing ring 4 rotates, thus preventing the first mounting plate 507 from being unable to be pressed down. 7. This ensures the stability of the backpack 201 while the bearing ring 4 rotates. When the backpack 201 needs to be removed, the bearing ring 4 is rotated back to its original position. At this time, the electric push cylinder 3 5085 extends so that its drive end passes through the through hole and inserts into the slot 5084, and pushes the locking block 5082 out of the slot 5084. Then, the mounting plate 1 507 can be pulled up to reduce the distance between the upper hook 501 and the lower hook 502, so that the connecting strap 503 and the backpack 201 can be removed.

[0058] Please see the appendix Figure 7 - Appendix Figure 8 A vertical plate 510 is fitted to the lower side wall of the mounting plate 507. The vertical plate 510 is fixedly connected to the bearing ring 4. A trapezoidal groove is opened on the side wall of the vertical plate 510. A clamping plate 511 is slidably connected to the bottom of the lower hook 502. A pressing rod 512 is fixed on the side wall of the clamping plate 511.

[0059] Specifically, when the mounting plate 507 slides to the top, one end of the pressing rod 512 moves into the groove. At this time, the distance between the clamping plate 511 and the bottom of the lower hook 502 increases to facilitate the installation of the connection port 504. As the mounting plate 507 descends, the pressing rod 512 moves out from the bottom slope of the groove and abuts against the side wall of the upright plate 510, thereby pushing the clamping plate 511 to move to the bottom of the lower hook 502. This allows the two to work together to automatically clamp the extension layer and fix it on the lower hook 502, preventing the lower extension layer from falling off during the installation of the backpack 201. This eliminates the need for manual assistance in fixing the extension layer throughout the process.

[0060] Please see the appendix Figure 7 - Appendix Figure 8 Mounting plate 2 513 is hinged to bearing ring 4. A pull rope 514 is fixed at the bottom of mounting plate 2 513. The bottom end of pull rope 514 passes through bearing ring 4 and is fixedly connected to mounting plate 1 507.

[0061] Specifically, when the first mounting plate 507 slides to the top, the pull rope 514 remains loose, and the second mounting plate 513 drives the upper hook 501 to move downward, which can increase the operating space between the upper and lower hooks, making it easier to quickly hook or remove the backpack 201 connecting strap 503. This makes installation and disassembly more labor-saving and efficient, improving the convenience and work efficiency of loading and unloading the backpack 201. When the first mounting plate 507 slides down to the bottom, the pull rope 514 pulls the second mounting plate 513 to rotate vertically, fixing the distance between the upper hook 501 and the lower hook 502.

[0062] Please see the appendix Figure 9 The device 2 also includes a fire extinguisher rack 202, a hook 203, a leaflet storage box 204, a loudspeaker 205, a camera 206, and a warning light. The fire extinguisher rack 202, hook 203, and leaflet storage box 204 are fixedly installed on the outside of the support ring 4. The loudspeaker 205, camera 206, and warning light are fixed to the back panel 1 by support rods. The backpack 201 includes a bag body 2011, on which a power bank compartment 2012 and a reflective strip 2013 are provided.

[0063] Specifically, the fire extinguisher holder 202 is used to place fire extinguishers, the hook 203 is used to hang the daily necessities or promotional materials of the promoters, the leaflet storage box 204 is used to store promotional leaflets, and the support ring 4 can also be pre-set with walkie-talkie holders, emergency flashlight holders and other holders for fixing promotional materials, the warning light is used to warn people when taking pictures at the fire scene, the camera 206 is used for taking pictures, and the promotional speaker 205 is connected to a microphone via Bluetooth to amplify the promoter's voice. By installing the device 2 on the support ring 4 or the back plate 1, the burden on the promoter can be reduced, and it can also be made easier to pick up. The power bank compartment 2012 is used to charge electronic products.
