[0002] With the rapid development of modern society, vehicles have undoubtedly become the first choice for people's daily travel. However, with the increase in the number of vehicles, traffic safety issues have become increasingly prominent, especially in the event of traffic accidents or vehicle breakdowns, where vehicle warning signs have become an important tool for ensuring road safety. While traditional vehicle warning signs have played an important role in alerting vehicles behind and preventing secondary accidents, they often suffer from problems such as bulky design, large space occupation, and inconvenient storage. Utility Model Content

[0003] In view of this, the present invention aims to provide a portable vehicle warning sign that is simple to deploy, lightweight, and occupies little space.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A portable vehicle warning sign includes a mobile device and an inflatable warning sign disposed on the mobile device;

[0006] The mobile device includes a housing, a walking mechanism located at the bottom of the housing, and an inflation mechanism located in the housing. The inflation warning sign is connected to the inflation mechanism and has a stored state within the housing and a used state where it is inflated and extended above the housing.

[0007] Furthermore, the shell has a circular cross-section and includes a top plate and a bottom plate arranged vertically, as well as a side plate disposed between the top plate and the bottom plate, and the top plate is provided with a clearance hole for the inflatable warning sign to be inflated and extended.

[0008] Furthermore, the inflation mechanism includes a box body disposed in the housing and a fan disposed in the box body. The box body is provided with a connecting hole connected to the inflation warning sign, and the housing is provided with a ventilation matching hole corresponding to the ventilation hole of the box body.

[0009] Furthermore, it also includes a control unit disposed on the housing, and an obstacle avoidance sensor connected to the control unit, and the control unit is connected to both the walking mechanism and the inflation mechanism.

[0010] Furthermore, the walking mechanism includes a plurality of walking wheel assemblies disposed on the base plate, and the lines connecting the plurality of walking wheel assemblies form a triangle.

[0011] Furthermore, at least some of the walking components include walking wheels and drive units for driving the walking wheels to rotate, and each of the drive units is connected to the control unit.

[0012] Furthermore, the obstacle avoidance sensor is an infrared sensor; and / or, the side panel is provided with a plurality of LED lights connected to the control unit.

[0013] Furthermore, the box body is provided with a cover plate for covering the avoidance hole; and / or, the inflatable warning sign is provided with a triangular reflective strip.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] The portable vehicle warning sign described in this utility model, by setting up a moving device and an inflatable warning sign, can reduce the overall weight and volume of the device without affecting the warning effect of the warning sign, thereby reducing the storage space occupied.

[0016] Furthermore, by arranging the shell's cross-section as a circle and providing side plates between the top and bottom plates, this sandwich structure effectively protects the internal walking and inflation mechanisms, maximizes the use of the shell's internal space, and allows for quick deployment and retrieval of the inflatable warning sign through the clearance holes on the top plate. Integrating the fan-equipped housing into the shell allows for a compact layout, reduces overall space occupation, and prevents damage from external impacts or wear. The connecting holes and ventilation holes on the housing also ensure smooth airflow, guaranteeing uniform and rapid inflation of the warning sign.

[0017] Furthermore, connecting the obstacle avoidance sensor, walking mechanism, and inflation mechanism facilitates unified management and coordination of their operation, enabling intelligent control. Arranging the walking wheel assembly in a triangular pattern on the base plate ensures force balance in different directions, resulting in smoother movement of the walking mechanism and reducing deviation or tilting caused by uneven wheel force. It also provides better steering flexibility, making the walking mechanism more agile when turning. Connecting each drive component to the aforementioned unit facilitates differential control of each walking wheel, further enhancing the agility of the walking device.

[0018] Furthermore, using infrared sensors as obstacle avoidance sensors makes them unaffected by visible light, enhancing their all-weather capability. LED lights connected to the control unit on the side panel improve the visibility of the portable vehicle warning sign during movement in low light. A cover protects the internal structure of the obstacle avoidance holes, preventing dust, moisture, and other impurities from entering and extending the lifespan of the inflatable warning sign. Triangular reflective strips on the inflatable warning sign improve its visibility at night or in low-light environments, ensuring the device's effectiveness. Attached Figure Description

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] This embodiment relates to a portable vehicle warning sign, which is simple to deploy, lightweight, and occupies little space.

[0037] In terms of overall structure, such as Figures 1 to 3 As shown, the portable vehicle warning sign in this embodiment includes a mobile device and an inflatable warning sign 4 disposed on the mobile device.

[0038] The mobile device includes a housing 11, a walking mechanism 3 located at the bottom of the housing 11, and an inflation mechanism located in the housing 11. An inflation warning sign 4 is connected to the inflation mechanism and has a stored state in the housing 11 and a used state after inflation and extension located above the housing 11.

[0039] Based on the above overview, in detail, the portable vehicle warning sign of this embodiment can reduce the overall weight and volume of the device without affecting the warning effect, thereby reducing the storage space occupied. Furthermore, in this embodiment, the inflatable warning sign 4 can be made of reinforced nylon well-known to those skilled in the art, such as nylon with a PVC (Polyvinyl Chloride) coating; further details will not be provided here.

[0040] Furthermore, in specific implementation, the inflatable warning sign 4 of this embodiment also includes a support portion and a main body portion of the warning sign, with an inflation port on the support portion for connection with inflation. The support portion of the inflatable warning sign 4 is bonded to the bottom of the box, and the inflation port abuts against the inflation structure.

[0041] At this point, as configured above, in this embodiment, as a preferred implementation, such as... Figure 1 and Figure 2 As shown, the shell 11 has a circular cross-section and includes a top plate 111 and a bottom plate 113 arranged vertically, as well as a side plate 112 located between the top plate 111 and the bottom plate 113. The top plate 111 has a clearance hole 1111 for the inflatable warning sign 4 to be inflated and extended. This sandwich structure effectively protects the internal walking mechanism 3 and inflation mechanism, maximizes the use of the internal space of the shell 11, and allows for the quick deployment and retrieval of the inflatable warning sign 4 through the clearance hole 1111 on the top plate 111.

[0042] Secondly, in specific implementation, a control panel and a power switch 1112 are also provided on the top plate 111 arranged on the top. The power switch 1112 and the controller are connected to the top panel by screw connection to ensure that it is firmly fixed and easy to replace and maintain.

[0043] Furthermore, in this embodiment, as a preferred implementation, it is... Figure 2 and Figure 3 As shown, the inflation mechanism includes a box 2 disposed in the housing 11 and a fan 21 disposed in the box 2. The box 2 is provided with a connecting hole 23 connected to the inflation warning sign 4, and the housing 11 is provided with a ventilation matching hole 1122 corresponding to the ventilation hole 22 of the box 2.

[0044] Integrating the box 2 with the fan 21 inside the housing 11 allows for a compact layout, reduces overall space occupation, and avoids damage caused by external impacts or wear. The box 2 also prevents the fan 21 from being damaged by external moisture and dust during operation. The ventilation holes 22 and ventilation mating holes 1122 provided on the box 2 also ensure smooth airflow and ensure that the inflation warning sign 4 expands evenly and quickly.

[0045] Furthermore, in specific implementation, to be detailed, such as Figure 5 As shown, the inflatable warning sign 4 in this embodiment also includes a support part 42 and a warning sign body 41. The support part 42 is provided with a first inflation port 43 connected to the inflation mechanism. The support part 42 of the inflatable warning sign 4 is bonded to the bottom of the box body 2, and the first inflation port 53 abuts against the connecting hole 23.

[0046] In this embodiment, as a preferred implementation, by Figure 2 As shown, it also includes a control unit 1113 mounted on the housing 11, and an obstacle avoidance sensor 1131 connected to the control unit 1113. The control unit 1113 is also connected to the walking mechanism 3 and the inflation mechanism. This configuration facilitates unified management and coordination of the operation of the obstacle avoidance sensor 1131, the walking mechanism 3, and the inflation mechanism, enabling intelligent control. Furthermore, users can easily set parameters and monitor the equipment status through the control unit 1113, improving ease of operation.

[0047] It should be noted that, in specific implementations, the control unit 1113 also includes a Bluetooth module. During use, the control unit 1113 can be remotely operated via a mobile phone through the Bluetooth module, thus further ensuring the safety of the operator. Of course, any related structures not mentioned in this embodiment, such as the display screen and Bluetooth module, can be structures well-known to those skilled in the art in related products.

[0048] Understandably, in this embodiment, as a preferred implementation, the walking mechanism 3 includes multiple walking wheel assemblies 312 mounted on the base plate 113, with the lines connecting the multiple walking wheel assemblies forming a triangle. This triangular arrangement of the walking wheel assemblies on the base plate 113 ensures force balance in different directions, making the walking mechanism 3 move more smoothly and reducing deviation or tilting caused by uneven force on the wheels. It also provides better steering flexibility, making the walking mechanism 3 more agile when turning. Furthermore, the triangular layout is structurally simpler than other polygonal layouts, helping to reduce manufacturing costs and design complexity, lower maintenance costs, and enhance market competitiveness. In addition, the walking wheel assemblies 312 also include unpowered omnidirectional wheels 32.

[0049] Moreover, in this embodiment, as a preferred implementation, by Figure 4 As shown, at least a portion of the walking components include walking wheels 312 and drive units 313 for driving the walking wheels 312 to rotate, and each drive unit 313 is connected to the control unit 1113. The advantage of this arrangement is that it facilitates differential control of each walking wheel 312, further enhancing the agility of the walking device.

[0050] In this embodiment, specifically, the walking component further includes a protective cover 31. The walking component is connected to the base plate 113 via a mounting part 311 on the protective cover 31. The protective cover 31 prevents dust and debris from entering the drive unit 313 and affecting its service life. Furthermore, the drive unit 313 and the walking wheel 312 employ a belt drive system. This ensures smooth transmission of the walking component, a simple structure, and easy maintenance. Belt drives also offer significant elasticity and flexibility, absorbing impacts and vibrations. When the walking wheel 312 is overloaded, the drive belt can slip on the pulley, protecting the motor from overload damage and further enhancing the reliability and durability of the walking component.

[0051] In addition, it is worth mentioning that the main body of the walking component is located in the housing 11, which reduces the overall outline protrusion and further reduces the space occupied by the portable vehicle warning sign during storage.

[0052] Furthermore, in this embodiment, as a preferred implementation, the obstacle avoidance sensor 1131 is an infrared sensor. This configuration allows the obstacle avoidance sensor 1131 to be unaffected by visible light, enhancing its all-weather obstacle avoidance capability. In addition, the side panel 112 is equipped with multiple LED lights 1121 connected to the control unit 1113, which can enhance the visibility of the portable vehicle warning sign during movement in low light conditions. Simultaneously, thanks to the low energy consumption of the LED lights 1121, the battery life of the portable vehicle warning sign can be improved.

[0053] It should be noted that, in this embodiment, in specific implementation, related structures not mentioned in the control unit 1113 of this embodiment, such as LED light 1121 and obstacle avoidance sensor 1131, can all adopt various structures in related products well known to those skilled in the art.

[0054] In this embodiment, as a preferred implementation, the housing 2 is provided with a cover plate 24 for covering the clearance hole 1111, and the inflatable warning sign 4 is provided with a triangular reflective strip. By providing the cover plate 24, the internal structure of the clearance hole 1111 can be protected, preventing dust, moisture and other impurities from entering, thus extending the service life of the inflatable warning sign 4. In addition, the reflective strip can improve the visibility of the warning sign at night or in low-light environments, ensuring the effectiveness of the equipment. Furthermore, preferably, the inflatable warning sign 4 can also be provided with a cool light, which can further improve the visibility of the inflatable warning sign 4 at night.

[0055] In this embodiment, when the portable vehicle warning sign is pressed, the entire device is powered on. At this time, it can be connected to the control unit 1113 via Bluetooth using a mobile phone, allowing remote control of the control unit 1113 to deploy the portable vehicle warning sign. Furthermore, pressing and holding the power switch 1112 for one second puts the portable vehicle warning sign into automatic mode. In this mode, the LED light 1121 on the side panel 112 automatically illuminates upon receiving a signal from the control unit 1113. The walking mechanism 3 relies on the signal sent to the control unit 1113 by the obstacle avoidance sensor 1131, and is guided by the control unit 1113 to the designated deployment location.

[0056] Once the portable vehicle warning sign reaches its deployment position, the wheels 312 automatically lock. At this time, the fan 21 inside the housing 2 starts, and airflow enters the housing 2 through the ventilation holes 1122 on the housing 11 and the ventilation holes 22 on the housing 2. The airflow is then blown by the fan 21 into the connecting hole 23, which is connected to the first inflation port 43 on the inflatable warning sign 4. This causes the inflatable warning sign 4 to inflate through the clearance holes 1111 on the top plate 111, thus completing the deployment. At this point, the inflatable warning sign 4 is fully inflated, and the triangular reflective strip on it can reflect the headlights of vehicles approaching from behind, serving as a warning.

[0057] When it is time to retrieve, the portable vehicle warning sign can be automatically returned under the guidance of the obstacle avoidance sensor 1131 via Bluetooth remote control of a mobile phone. At the same time, the fan 21 located in the housing 2 receives the instruction from the control unit 1113 and reverses from blowing to sucking air, retracting the inflatable warning sign 4 into the housing 11. During the return process, the LED light 1121 located on the side panel 112 will be continuously lit to improve the visibility of the portable vehicle warning sign under various conditions.

[0058] The portable vehicle warning sign of this utility model can be automatically deployed by setting up a mobile device and an inflatable warning sign 4. It can also reduce the overall weight and volume of the equipment without affecting the warning effect of the warning sign, thereby reducing the storage space occupied.

[0059] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
