DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In order to solve the technical problem that when the display screen of the promotional device fails, the traditional promotional device cannot automatically replace the damaged part of the display screen, and must wait for the maintenance personnel to repair it, which not only affects the promotion process, but also affects the promotion effect. Figure 1 - Fig.10 As shown, the following preferred technical solutions are provided: A sports health management propaganda device comprises a mobile base 1 and a lifting mechanism 2 fixedly mounted on the mobile base 1. The position of the propaganda device can be changed by the mobile base 1, thereby improving the flexibility of the use of the propaganda device. A display housing 3 is fixedly mounted on the top of the lifting mechanism 2, so as to protect and support the components inside the display housing 3. A plurality of loudspeakers 4 are embedded and fixedly mounted on the outer wall of one side of the display housing 3, which play a role of amplification and are used to broadcast the content displayed by the propaganda device. The combination of audio and video makes the propaganda content more vivid and vivid, so as to enhance the propaganda effect. A visual probe 5 is also fixedly arranged on the outer wall of one side of the display housing 3, so as to monitor the running state of the propaganda device. A controller 6, a vibration sensor 7 and two rack plates 30 are fixedly mounted on the inner side walls of the display housing 3, respectively. The controller 6 is used to control the orderly operation of each component, and the vibration sensor 7 is used to monitor the vibration degree of the propaganda device, so as to judge whether the propaganda device is impacted by the outside.

[0021] The inner side wall of the display housing 3 is also slidably provided with a traction component 1 8 and a traction component 2 9, respectively, which are meshed with the rack plate 30. Through such a setting, when the traction component 1 8 and the traction component 2 9 are in operation, they will slide on the inner side wall of the display housing 3 under the meshing action. The side wall of the traction component 1 8 close to the traction component 2 9 is fixedly connected with a card connection component 1 10, and the side wall of the traction component 2 9 close to the traction component 1 8 is fixedly connected with a card connection component 2 20. When the traction component 2 9 and the traction component 1 8 can achieve synchronous operation, the card connection component 10 and the card connection component 20 are fixedly connected. There will be no snap-fitting relationship between the components 20. When the traction component 2 9 and the traction component 1 8 cannot operate synchronously due to external factors, a snap-fitting relationship will be formed between the snap-fitting component 10 and the snap-fitting component 2 20, and one of the traction components 1 8 or the traction component 2 9 will be closed, so that the traction component 1 8, the traction component 2 9, the snap-fitting component 10 and the snap-fitting component 2 20 become an integral structure, and then the overall structure is driven to operate synchronously through one of the traction components 1 8 or the traction components 2 9, thereby solving the problem that the traction component 2 9 and the traction component 1 8 cannot operate synchronously.

[0022] A pair of guide assemblies 40 are fixedly installed between the top surface and the bottom surface of the inner cavity of the display housing 3. The two guide assemblies 40 are arranged in symmetrical positions. A display assembly 60 is slidably arranged on the outer wall of the guide assembly 40. The display assembly 60 is used to display the promotional content, and the guide assembly 40 is used to guide the direction of the display assembly 60 to prevent the display assembly 60 from being damaged due to excessive bending angle. The display assembly 60 is movably connected with the traction assembly 1 8 and the traction assembly 2 9 respectively. The traction assembly 1 8 and the traction assembly 2 9 play a traction role on the display assembly 60, and can drive the display assembly 60 to slide on the guide assembly 40. A photoelectric gate 50 is fixedly installed on the bottom surface of the display housing 3, which is used to judge how far the display assembly 60 has moved to judge whether it needs to stop moving.

[0023] When the vibration detected by the vibration sensor 7 is higher than the set threshold, it is determined that the propaganda device has been impacted by the outside world. At this time, the controller 6 starts the visual probe 5 to observe the display component 60 of the propaganda device to determine whether the display component 60 of the propaganda device is damaged. If the display component 60 of the propaganda device is not damaged, the entire propaganda device continues to operate. If the display component 60 fails, at this time, the traction component 1 8 and the traction component 2 9 are started to move synchronously in the same direction, and traction force is generated on the display component 60, driving the display component 60 to slide on the guide component 40. When the display component 60 starts to slide, the traction component 1 8 and the traction component 2 9 are started to move synchronously in the same direction, and the .... When the display component 60 starts to slide, the traction component 1 Through the photoelectric gate 50, when the visual probe 5 determines that the faulty part has been moved out of the display area of ​​the promotional device, the traction component 1 8 and the traction component 2 9 stop operating, and in this process, the photoelectric gate 50 will determine how far the display component 60 has moved relative to the default display part, and then the controller 6 will light up the part of the display component 60 in the display area of ​​the promotional device, and the other parts will be in a non-lighting state. Through such a setting, the part of the display component 60 with a fault can be moved away from the display area of ​​the promotional device, and the part of the display component 60 without a fault can be moved to the display area of ​​the promotional device for content display.

[0024] The lifting mechanism 2 includes an electric telescopic rod 21 fixedly mounted on the mobile base 1, the output end of the electric telescopic rod 21 is fixedly connected to a mounting bracket 22, the display housing 3 and the mounting bracket 22 are fastened by studs, the mounting bracket 22 is used to support and fix the display housing 3, and the electric telescopic rod 21 is used to adjust the height of the display housing 3 to be suitable for different promotional occasions, thereby enhancing practical flexibility.

[0025] The display housing 3 includes a shell 31, and an annular groove 32 is provided on the bottom surface of the inner cavity of the shell 31. The annular groove 32 is consistent with the shape of the display component 60, and the annular groove 32 is arranged directly below the display component 60. The photoelectric gate 50 is fixedly installed on the bottom surface of the inner cavity of the annular groove 32. A sliding groove 33 is provided on the side wall of the inner cavity of the shell 31. The traction component 1 8 and the traction component 2 9 are both embedded and slidably installed in the inner cavity of the sliding groove 33.

[0026] The guide component 40 includes a U-shaped frame 401 fixedly installed on the top surface of the inner cavity of the shell 31 and a U-shaped frame 402 fixedly installed on the bottom surface of the inner cavity of the shell 31. A U-shaped guide plate 403 is fixedly installed between the bottom surface of the U-shaped frame 401 and the top surface of the U-shaped frame 402. The display component 60 is slidably arranged on the outer surface of the U-shaped guide plate 403. The U-shaped guide plate 403 is used to limit the bending angle of the display component 60 to prevent the display component 60 from bending too much when the traction component 1 8 and the traction component 2 9 tow the display component 60, causing additional damage to the display component 60. In addition, the U-shaped guide plate 403 is arranged in cooperation with the traction component 1 8 and the traction component 2 9, so that the display component 60 is always in a flattened state without wrinkling, which not only ensures a good display effect, but also prevents the display component 60 from being damaged by wrinkles, thereby reducing the probability of damage to the display component 60.

[0027] The traction component 8 includes a first slide plate 84 embedded and slidably installed in the inner cavity of the slide groove 33. The first slide plate 84 is fixedly connected to a clamping component 10 on the side wall close to the traction component 2 9. A first dual-axis motor 81 is fixedly installed on the outer wall of the first slide plate 84. The output shafts on both sides of the first dual-axis motor 81 are respectively fixedly sleeved with first gears 82. The first gear 82 is meshedly connected to the rack plate 30. A first traction rod 83 is fixedly installed on the outer wall of the first gear 82.

[0028] The traction component 2 9 includes a second slide plate 94 embedded and slidably installed in the inner cavity of the slide groove 33. The second slide plate 94 is fixedly connected to a clamping component 20 on the side wall close to the first slide plate 84. A second dual-axis motor 91 is fixedly installed on the outer wall of the second slide plate 94. Second gears 92 are fixedly sleeved on the output shafts on both sides of the second dual-axis motor 91. The second gear 92 is meshingly connected to the rack plate 30. A second traction rod 93 is fixedly installed on the outer wall of the second gear 92.

[0029] The display component 60 includes a film substrate 601, and an LED module 602 is arranged on the outer surface of the film substrate 601. The film substrate 601 is a flexible material, and therefore can drive the LED module 602 to bend or fold. A plurality of pins 603 are fixedly installed on the bottom surface of the film substrate 601, and the plurality of pins 603 are arranged at equal intervals. When the film substrate 601 drives the LED module 602 to move, the pins 603 will move synchronously, and the pins 603 will pass through the photoelectric gate 50 to determine how far the film substrate 601 drives the LED module 602 to move. A pair of pressure sensors 605 are fixedly installed on the side walls of the two end faces of the film substrate 601, and an L-shaped connecting rod 604 is connected to the outer wall of the pressure sensor 605. The L-shaped connecting rod 604 is correspondingly movably sleeved on the first traction rod 83 and the second traction rod 93. The traction component 1 8 and the traction component 2 When the first traction rod 83 and the second traction rod 93 move, the display assembly 60 can be driven to slide on the outer surface of the U-shaped guide plate 403 as a whole through the first traction rod 83 and the second traction rod 93, and the pressure sensor 605 is used to determine whether the traction assembly 1 8 and the traction assembly 2 9 are operating synchronously. When the pressure value of the pressure sensor 605 does not exceed the set threshold range, it means that the traction assembly 1 8 and the traction assembly 2 9 are operating synchronously. When the pressure value of the pressure sensor 605 exceeds the set threshold range, it means that the traction assembly 1 8 and the traction assembly 2 9 are not operating synchronously, indicating that the display assembly 60 may be broken and wrinkled due to excessive tension, both of which will affect the display effect. A cable outlet 606 is fixedly installed on the side wall of one end of the film substrate 601. The cable outlet 606 is electrically connected to the LED module 602, and the cable outlet 606 plays the role of powering the LED module 602 and transmitting data.

[0030] Specifically, when the vibration detected by the vibration sensor 7 is higher than the set threshold, it is determined that the publicity device has been impacted by the outside world. At this time, the controller 6 activates the visual probe 5 to observe the LED module 602 in the display area of ​​the publicity device to determine whether the LED module 602 is damaged. If the LED module 602 is not damaged, the entire publicity device continues to operate. If the LED module 602 fails and affects normal display, the first dual-axis motor 81 and the second dual-axis motor 91 are started to rotate. Since the first gear 82 and the second gear 92 are meshed with the rack plate 30, the film substrate 601 is pulled by the first traction rod 83, the second traction rod 93 and the L-shaped connecting rod 604, and the film substrate 601 is driven to slide on the outer surface of the U-shaped guide plate 403. When the film substrate 601 starts to slide, the LED module 602 and the pins 603 will also move synchronously with the film substrate 601. In this process, different pins 603 will successively pass through the photoelectric gate 5. 0. When the visual probe 5 determines that the faulty part of the LED module 602 has moved out of the display area of ​​the promotional device, the first dual-axis motor 81 and the second dual-axis motor 91 stop rotating, and in this process, the photoelectric gate 50 counts the number of pins 603 that pass through. Since the adjacent pins 603 are arranged at equal intervals, the controller 6 can determine how far the LED module 602 has moved relative to the default display part through these characteristics, and then the controller 6 lights up the part of the LED module 602 in the display area of ​​the promotional device, while the other parts are in a non-lighting state. Through such a setting, the faulty part of the display component 60 can be moved away from the display area of ​​the promotional device, and the normal part of the LED module 602 can be moved to the display area of ​​the promotional device for content display. Compared with traditional devices, the ability to resist unexpected risks is enhanced, and even if the LED module 602 fails, it will not affect the promotional effect and progress.

[0031] In order to solve the technical problem that a layer of dust falls on the photodetector 503, causing the photodetector 503 to inaccurately count the number of pins 603 passing through, as shown in FIG. Figure 2 , Figure 6 , Fig. 9 -10 and Fig.12 As shown, the following preferred technical solutions are provided: The photoelectric gate 50 includes a fixed plate 501 fixedly mounted on the bottom surface of the inner cavity of the annular groove 32, two support plates 502 are fixedly mounted on the top surface of the fixed plate 501, a number of photodetectors 503 are respectively fixedly mounted on the inner side walls of the two support plates 502, and rotating gears 504 are installed on the inner side walls of the two support plates 502 for common rotation, and a number of bristles 505 are respectively planted on the outer walls on both sides of the rotating gear 504.

[0032] Specifically, after being placed for a long time, the photodetector 503 will inevitably accumulate a layer of dust. If it is not cleaned, when the pin 603 passes through the gap of the photodetector 503, the photodetector 503 will not accurately count the number of pins 603 passing through. As a result, when the controller 6 turns on the LED module 602, the lighting area of ​​the LED module 602 and the display area of ​​the promotional device will be misaligned. In order to solve this problem, the present invention provides a rotating gear 504 and a brush 505. When the traction component 1 8 and the traction component 2 9 pull the film substrate 601 to slide on the outer surface of the U-shaped guide plate 403, the LED module 602 and the pin 603 will also synchronously follow the film substrate 601. The plate 601 moves, and during this process, different pins 603 will successively pass through the gaps of the photodetector 503. While passing through, the pins 603 will generate thrust on the rotating gear 504, thereby causing the rotating gear 504 to rotate. Since the pins 603 are continuous, the rotating gear 504 will rotate continuously. During the rotation of the rotating gear 504, the photodetector 503 will be cleaned by the bristles 505 to ensure that the photodetector 503 has good cleanliness, and the number of pins 603 passing through can be accurately counted to prevent the problem of misalignment between the lighting area of ​​the LED module 602 and the display area of ​​the promotional device, which is beneficial to improving the display effect and the promotional effect.

[0033] In order to solve the technical problem that the traction assembly 2 9 and the traction assembly 1 8 cannot operate synchronously, resulting in wrinkles and additional damage to the LED module 602 during the movement, as shown in FIG. Figure 2 - Figure 4 , Figure 7 -8 and Fig.10 -11, the following preferred technical solutions are provided: The clamping component 10 includes an electric push rod 101, and the outer walls on both sides of the output end of the electric push rod 101 are respectively embedded with elastic sliding blocks 102, the outer wall of the block 102 is fixedly installed with a contact 103, and the side wall of the block 102 close to the clamping component 20 is provided with an arc surface 104.

[0034] The second clamping component 20 includes an electric push rod 201, a slot 202 is provided at the output end of the electric push rod 201, and clamping slots 203 are respectively provided on the inner walls on both sides of the inner cavity of the slot 202. A contact 204 is fixedly installed on the side wall of the inner cavity of the slot 203, and a push rod 205 is slidably installed through the side wall of the inner cavity of the slot 203. The push rod 205 and the outer wall of the output end of the electric push rod 201 are elastically connected by a spring 206.

[0035] Specifically, when a fault occurs in the LED module 602 and the faulty part needs to be moved out of the display area of ​​the promotional device, it is necessary to start the traction component 2 9 and the traction component 1 8 to operate synchronously in the same direction, thereby moving the faulty part of the LED module 602 out of the display area of ​​the promotional device. When the traction component 1 8 and the traction component 2 9 move, the pressure sensor 605 is used to determine whether the traction component 2 9 and the traction component 1 8 are in a synchronous operation state.

[0036] When the traction components 2 9 and the traction components 1 8 can realize synchronous operation, no clamping relationship is formed between the clamping components 10 and the clamping components 2 20. When the traction components 2 9 and the traction components 1 8 cannot realize synchronous operation under the influence of external factors, at this time, the electric push rod 1 101 and the electric push rod 2 201 are synchronously extended. When extended to a suitable length, the clamping block 102 will abut against the edge of the slot 202. Under the action of the arc surface 104, the clamping block 102 will retract into the interior of the electric push rod 1 101. As the electric push rod 1 101 and the electric push rod 2 201 continue to extend, when the clamping block 102 moves to the position of the clamping slot 203, the clamping block 102 will retract into the electric push rod 1 The outside of rod 101 pops out and is snapped into the inner cavity of the slot 203. At this time, contact 103 contacts contact 204 and transmits an electrical signal to the controller 6. The controller 6 controls the electric push rod 101 and the electric push rod 201 to stop extending synchronously, and closes one of the traction components 1 8 or the traction components 2 9. This makes the traction components 1 8, the traction components 2 9, the snap-in components 10 and the snap-in components 2 20 an integral structure, and then the operation of one of the traction components 1 8 or the traction components 2 9 drives the overall structure to operate synchronously, thereby solving the problem that the traction components 2 9 and the traction components 1 8 cannot operate synchronously.

[0037] When the maintenance personnel adjust the traction component 2 9 and the traction component 1 8 to a state of synchronous operation, the maintenance personnel push the block 102 out of the slot 202 by pressing the push rod 205, and then control the electric push rod 1 101 and the electric push rod 2 201 to shorten synchronously through the controller 6, so as to release the clamping relationship between the clamping component 10 and the clamping component 2 20, and finally restore the electric push rod 1 101 and the electric push rod 2 201 to their original positions. When the traction component 2 9 and the traction component 1 8 cannot operate synchronously again, the above operations can be repeated.

[0038] The above arrangement can not only prevent the LED module 602 from being pulled out and causing additional damage, but also prevent the LED module 602 from generating wrinkles during the movement, thereby affecting the display effect and the publicity effect.
