Description

Technical Field

[0001] The present invention relates to the field of road signs, and in particular to a smart mobile and voice - dialogue - enabled guiding sign. Background Art

[0002] A guiding sign is a traffic facility set in public places to provide guiding information for pedestrians. Currently, traditional guiding signs are static signs. Not only is their position immovable, but the guiding information is also fixed. Therefore, their scope of use is limited. Currently, in many indoor places, intelligent guiding signs are adopted, which are paired with corresponding voice intelligent interaction devices and can conduct voice conversations with users to achieve the purpose of information exchange.

[0003] However, for existing intelligent guiding signs, most of their installation positions are also fixedly installed, resulting in poor flexibility. At the same time, existing intelligent guiding signs, because they carry relatively delicate electronic devices, are mostly used indoors and do not have the effects of sun protection and rain protection, resulting in their inability to work normally outdoors for a long time. Therefore, this solution proposes a smart mobile and voice - dialogue - enabled guiding sign. Summary of the Invention

Specific implementation manners

[0037] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination can be formed between the following-described embodiments or technical features to form a new embodiment.

[0038] Embodiment 1:

[0039] Please refer to Figure 1 - Figure 9 , an intelligent mobile voice-guided sign of this embodiment includes:

[0040] Support mechanism, which includes a hollow support column 2 and a movable base 1 installed at the bottom of the support column 2. A crawler is installed at the bottom of the movable base 1. A storage battery and a motor for driving the crawler to operate are installed inside the base 1. An infrared sensor and an ultrasonic sensor are installed outside the base 1. An intelligent voice interaction device 7 is installed outside the support column 2. The intelligent voice interaction device 7 includes a tablet computer and a housing installed outside the tablet computer. A voice receiver and a voice outputter are provided on the tablet computer. A speaker connected to the voice outputter and a camera connected to the tablet computer are also installed on the housing of the intelligent voice interaction device 7. A wireless Wi-Fi component connected to the tablet computer is installed inside the housing. A protective cover 8 is installed on the top of the intelligent voice interaction device 7. The protective cover can prevent the tablet computer from being directly irradiated by the sun and rained on. The setting of the wireless Wi-Fi component can be used to connect the intelligent voice interaction device 7 to the network. After receiving the information transmitted by the remote terminal, it is processed by the tablet computer and then executed. At the same time, the user can also input the information to be queried through the tablet computer and finally display it intuitively through the tablet computer. A navigation system is installed inside the tablet computer. Both the infrared sensor and the ultrasonic sensor are connected to the tablet computer. Therefore, the walking path can be planned according to the navigation system at the remote terminal, and the path and pedestrians can be identified by relying on the camera. With the cooperation between the infrared sensor and the ultrasonic sensor and the tablet computer, obstacle avoidance can be achieved, so as to ensure the safe progress of the vehicle body.

[0041] Refer to Figure 1 、 Figure 3 and Figure 4 For the electronic signboard, it includes a display screen 6 and a mounting plate 5 fixedly connected to the outer periphery of the support column 2. A storage groove for receiving the display screen 6 is provided on the bottom surface of the mounting plate 5. A mounting shaft 18 rotatably connected to the inner wall of the storage groove is fixed at the top of the display screen 6. The number of electronic signboards is set to be multiple. A fixed cylinder 25 coaxially arranged with the mounting shaft 18 is fixed at one end of the mounting plate 5. The other end of the fixed cylinder 25 is fixedly connected to the outer periphery of the support column 2. The display screen 6 is connected to the tablet computer. By inputting road sign information on the tablet computer and then displaying it through different display screens 6. When it does not rain, the display screen 6 is in an open state, so as to ensure that the information on the display screen 6 will not be covered. When it rains, the display screen 6 will be received into the storage groove 6 under the rotation of the mounting shaft 18, so as to avoid water ingress into the display screen 6.

[0042] Refer to Figures 1-3 and Figures 5-8Covering mechanism, which includes an umbrella cover installed on the top of the support column 2 and an adjustment component installed on the support column 2 for driving the opening and closing of the umbrella cover. The umbrella cover includes a plurality of fixed umbrella ribs 24 hinged to the top of the support column 2 and an umbrella surface 3 fixed on the top surfaces of the plurality of fixed umbrella ribs 24. A chute 23 is provided on the outer periphery of the support column 2 along its axial direction. The adjustment component includes a moving ring 21 movably sleeved on the outer periphery of the support column 2 and a plurality of connecting rods 13 hinged to the outer periphery of the moving ring 21. The number of the connecting rods 13 is the same as that of the fixed umbrella ribs 24. The other ends of the plurality of connecting rods 13 are respectively hinged to a corresponding fixed umbrella rib 24. When the umbrella cover is opened, the plurality of fixed umbrella ribs 24 are also in an open state. At this time, the umbrella cover is directly above the plurality of electronic signs, so that the electronic signs can be protected from the sun's irradiation, which helps to extend the service life of the display screen 6. When it rains, the moving ring 21 is driven to move downward, so as to drive the fixed umbrella ribs 24 to rotate downward through the plurality of connecting rods 13, and then the umbrella cover is closed. This not only reduces the overall profile of the sign, thereby reducing wind resistance, but also can cover the electronic sign inside the umbrella cover to play a role in rain protection.

[0043] Refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 , a protection mechanism, which includes a plurality of movable umbrella ribs 9 provided on the bottom surface of the umbrella cover and a protection surface 4 covering the top surfaces of the movable umbrella ribs 9. The plurality of movable umbrella ribs 9 are respectively movably connected to the bottom surfaces of the plurality of fixed umbrella ribs 24. A connection component is installed between the movable umbrella ribs 9 and the support column 2 for driving the movable umbrella ribs 9 to open when the umbrella cover is closed and driving the movable umbrella ribs 9 to close when the umbrella cover is opened. In the case where the umbrella cover is opened, the protection surface 4 and the movable umbrella ribs 9 in the protection mechanism are both received on the bottom surface of the umbrella cover, and the edge of the protection surface 4 is also located inside the umbrella cover, so as to avoid the protection surface 4 blocking too much line of sight. During the process of closing the umbrella cover, the movable umbrella ribs 9 can be gradually pushed out of the umbrella cover through the connection component, so that the protection surface 4 extends to the outside of the umbrella cover, thereby increasing the rain shielding area of the umbrella cover, so that the electronic signs near the bottom of the support column can also be covered by the protection mechanism to avoid rain erosion.

[0044] Refer to Figure 3 - Figure 5 and Figure 8, the connecting component includes a connecting column 11 fixed to one end of the movable umbrella rib 9, a limiting sleeve 12 movably sleeved outside the connecting column 11, and a guide wheel 15 fixed to the bottom surface of the fixed umbrella rib 24 connecting the movable umbrella rib 9. The limiting sleeve 12 is fixedly connected to the fixed umbrella rib 24. A connecting groove for the connecting column 1 to pass through is formed on the connecting rod 13. The other end of the connecting column 11 passes through the connecting groove and is fixed with a connecting rope 14. The other end of the connecting rope 14 passes through the guide wheel 15 and is fixedly connected to the outer periphery of the support column 2. An elastic member is installed on the connecting column 11. The elastic member includes a spring block 10 fixed to the outer periphery of the connecting column 11 and a spring movably sleeved outside the connecting column 11. One end of the spring is fixedly connected to the spring block 10, and the other end of the spring is fixedly connected to the limiting sleeve 12. When the umbrella cover is opened, the moving ring 21 moves upward, thereby driving the fixed umbrella rib 24 to rotate upward and open. The movable umbrella rib 9 rotates synchronously with the fixed umbrella rib 24. At this time, the connecting rope 14 is gradually tightened, thereby driving the movable umbrella rib 9 to move toward the side close to the support column 2, and further gradually folding the protective surface 4 to the bottom surface of the umbrella cover. Until the umbrella cover is completely opened, the edge of the protective surface 4 is also completely received into the bottom surface of the umbrella cover. At this time, the spring is in a compressed state. When the umbrella cover is folded, the moving ring 21 moves downward, and the fixed umbrella rib 24 rotates downward, so that the connecting rope 14 is gradually relaxed, and the connecting column 11 will also gradually move outward from the umbrella cover under the action of the spring, thereby driving the movable umbrella rib 9 and the protective surface 4 to gradually move outside the umbrella cover, and further expanding the covering surface of the umbrella cover, using the protective surface 4 to cover the electronic sign below to prevent it from being rained on.

[0045] Embodiment 2:

[0046] Combined with Figure 3 - Figure 5, on the basis of Embodiment 1, the further improvement of this embodiment lies in: a driving mechanism, which is installed inside the support column 2 and is used to drive the adjustment component to open and close the umbrella cover while driving the installation shaft 18 to rotate. The driving mechanism includes an electric push rod 28 installed inside the support column 2 and a movable column 16 fixed to the output end of the electric push rod 28. A plurality of installation grooves 20 are provided on the outer periphery of the movable column 16 along its axial direction. The positions of the installation grooves 20 correspond to the positions of the fixed cylinders 25. A fixed rack 19 arranged along the axial direction of the movable column 16 is fixed on the inner wall of one long side of the installation groove 20. One end of the installation shaft 18 extends into the installation groove 20 and is fixed with a linkage gear 17 meshing with the fixed rack 19. A connecting block 22 is fixed to the inner ring of the moving ring 21, and one end of the connecting block 22 penetrates through the sliding groove 23 and is fixedly connected to the outer periphery of the movable column 16. The electric push rod 28 is connected to the tablet computer. After the wireless Wi-Fi component receives the instruction transmitted by the remote terminal, it will adjust the state of the electric telescopic rod 28 through the tablet computer. When it rains, the electric telescopic rod 28 is started to contract, thereby driving the movable column 16 to descend. During the descent of the movable column 16, the moving ring 21 and a plurality of fixed racks 19 are driven to descend synchronously. During the descent of the moving ring 21, the umbrella cover will be gradually closed. At the same time, during the descent of the fixed rack 19, the linkage gear 17 will be driven to rotate forward, thereby driving the installation shaft 18 to rotate forward and gradually closing the display screen 6 into the storage groove. On the contrary, when the electric push rod 28 extends, it will drive the movable column 16 to move upward, thereby driving the moving ring 21 to move upward while also driving a plurality of fixed racks 19 to move upward. Thus, the umbrella cover can be opened while driving the linkage gear 17 to reverse, so that the display screen 6 can be driven to rotate and opened from the storage groove, achieving the purpose of closing the display screen 6 while closing the umbrella cover and opening the display screen 6 while opening the umbrella cover.

[0047] Referring to Figure 1 and Figure 3 , the number of the sliding grooves 23 and the connecting blocks 22 are both set to 2 - 3, and the outer walls of both sides of the connecting block 22 are in contact with the long sides of both sides of the sliding groove 23. Setting a plurality of connecting blocks 22 can make the force on the moving ring 21 uniform, so that it moves more smoothly. The contact between the outer wall of the connecting block 22 and the outer wall of the sliding groove 23 can prevent the moving ring 21 from shaking.

[0048] Embodiment 3:

[0049] Combined with Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 9, on the basis of Embodiment 1 - Embodiment 2, the further improvement of this embodiment lies in that: any electronic signboard is arranged directly below one of the fixed umbrella ribs 24. One end of the mounting shaft 18 away from the support column 2 extends to the outside of the mounting plate 5 and is fixed with a rope pulley 26. A pull rope 27 is wound around the outer periphery of the rope pulley 26. The other end of the pull rope 27 is fixedly connected to the bottom surface of the fixed umbrella rib 24 directly above it. When the movable column 16 descends to drive the umbrella cover to close, it will drive the mounting shaft 18 to rotate forward. At this time, the rope pulley 26 follows the mounting shaft 18, so that the pull rope 27 can be gradually wound around the rope pulley 26. During this process, the pull rope 27 will also pull the fixed umbrella rib 24 to rotate downward. Until the umbrella cover is closed, the pull rope 27 also remains in a state of tightly fixing the fixed umbrella rib 24, so as to further prevent the umbrella cover from being blown open by strong winds. On the contrary, when the movable column 16 moves upward, it will drive the fixed umbrella rib to open, and at the same time, it will also drive the mounting shaft 18 to rotate reversely. The rope pulley 26 will then gradually unwind the pull rope 27, so as not to hinder the opening of the fixed umbrella rib 24. After the fixed umbrella rib 24 is opened, the pull rope 27 is also in a taut state, which can further help the umbrella cover withstand greater wind force and prevent the umbrella cover from being overturned by strong winds.

[0050] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
