Description

Technical Field

[0001] This application relates to the field of traffic control, and in particular to a multi-wheeled controllable warning cone. Background Technology

[0002] Warning traffic cones, as core facilities for traffic management and road safety, are widely used in scenarios such as road construction, traffic accident rescue, and temporary traffic control. Their core functions are to delineate dangerous areas, guide traffic flow, and remind drivers to avoid risks. Traditional traffic cones are mostly made of plastic or rubber, using reflective strips coated on their surface to provide nighttime warnings. They can provide basic protection in normal environments, but with the increase in road traffic volume and the growing complexity of scenarios, their technical limitations are becoming increasingly apparent.

[0003] In terms of warning effectiveness, traditional traffic cones rely on static reflective strips for passive warning, which is significantly affected by environmental factors. At night, in low-visibility conditions such as rain, snow, or fog, the effective warning distance of the reflective strips is less than 30 meters, making it difficult to trigger drivers' evasive reactions in advance. Furthermore, the single reflective effect lacks dynamic warning characteristics, making them easily overlooked by drivers on road sections with blind spots, such as curves and sharp slopes, significantly increasing safety risks in the work area and at the rescue site. While some improved traffic cones attempt to incorporate alarm devices, the deployment of the cones and equipment requires workers to complete the installation in two separate stages, which prolongs the time exposed to hazardous environments and reduces the cones' stability due to the additional load, making them prone to tipping over.

[0004] In terms of mobility and deployment efficiency, traditional traffic cones rely entirely on manual handling, placement, and retrieval. Especially in high-traffic, high-speed mixed traffic scenarios such as national and provincial highways, manual operation is not only labor-intensive and inefficient, but also exposes workers to a high risk of collision with vehicles. Furthermore, traffic cones are prone to displacement or tipping due to vehicle airflow or human contact during use, requiring continuous inspection and repositioning by designated personnel, further diverting the attention of construction and rescue workers. In severe weather conditions such as high temperatures and heavy rain, the timeliness of manual inspection and repositioning is more susceptible to uncontrollable factors such as personnel fatigue and negligence, leading to gaps in safety warnings.

[0005] Regarding positioning and repositioning accuracy, existing traffic cones lack effective autonomous positioning and calibration capabilities. Whether for standardized deployment in construction areas or dynamic adjustments at rescue sites, they rely on manual visual positioning, making it difficult to guarantee uniform spacing and accurate positioning, thus affecting the scientific rigor of warning zone delineation. Some prototype traffic cones with automatic movement functions suffer from problems such as trajectory deviation and large repositioning errors due to the lack of high-precision positioning technology and reliable communication links, failing to meet the precise deployment requirements in complex scenarios. Although research indicates that wireless communication technologies such as UWB and Bluetooth can achieve centimeter-level positioning accuracy, these technologies have not yet been effectively integrated into the autonomous movement and repositioning system of traffic cones, failing to solve the fundamental problem of insufficient controllability in traditional traffic cone positioning.

[0006] Furthermore, there is room for improvement in the structural design of traditional traffic cones. Most traffic cones use a single cone structure, which has limited stability at the bottom and is prone to tipping over in strong winds or when scraped by vehicles; and their fixed shape results in a large space being occupied during storage and transportation, further reducing their ease of use.

[0007] In summary, the shortcomings of existing warning cones in terms of warning effectiveness, deployment safety, positioning accuracy, and structural stability make them unable to meet the demands of modern road safety for efficient, intelligent, and precise protection. Developing new types of traffic cones with autonomous movement, precise positioning, stable support, and dynamic warning functions has become an urgent need for the industry. This application is an improvement made to solve the above problems. Utility Model Content

[0008] The purpose of this application embodiment is to provide a multi-wheel controllable warning traffic cone. By implementing this application embodiment, the traffic cone can be moved freely and accurately returned to its original position.

[0009] To achieve the aforementioned objective, this application provides a multi-wheel controllable warning traffic cone, the technical solution of which is:

[0010] Includes a chassis and cones mounted on the chassis;

[0011] It also includes a fixed base located below the chassis. The bottom of the chassis is equipped with a set of wheels, which allows the chassis to move along the ground and return to its original position where it aligns with the fixed base.

[0012] Warning devices are installed at the top of the cones;

[0013] The positioning module is fixedly installed on the aforementioned chassis and / or fixed base.

[0014] The control module is fixedly installed on the chassis, and a wireless communication unit is provided between the positioning module and the control module. The positioning module can transmit position signals to the control module through the wireless communication unit, thereby controlling the road cone to move to the corresponding position.

[0015] In this embodiment, the wheel set includes at least two powered wheels or at least two powered wheels and one non-powered wheel. Specifically, at least two powered wheels are arranged on the same side of the bottom end of the chassis, and at least one non-powered wheel is arranged on the opposite side of the bottom end of the chassis. The projections of at least two powered wheels and at least one non-powered wheel on the bottom end of the chassis form a triangular support structure, which together constitutes a triangular force-bearing structure supporting the chassis 1, thereby improving the placement stability of the chassis 1.

[0016] Based on the first aspect, in one possible implementation, it further includes a drive unit and a control unit, which are connected by a mounting plate. Specifically, the drive unit includes a drive wheel, a drive motor, and a bracket. The drive motor is mounted on the bracket, and the drive wheel is connected to the drive motor via the bracket. For example, the drive wheel is connected to the drive shaft of the drive motor, and under the support of the bracket, the drive motor can drive the drive wheel to rotate, thereby moving the traffic cone.

[0017] In the above possible implementation, the control unit includes a servo motor and a gear set. The servo motor is mounted on the end of the mounting plate and is connected to the bracket through the gear set. Under the support of the mounting plate, the servo motor can drive the bracket to rotate through the gear set. In conjunction with the aforementioned drive wheel, since the drive wheel is connected to the bracket, the movement trajectory of the drive wheel can change with the rotation of the bracket, thereby enabling the free movement of the traffic cone.

[0033] To better understand the embodiments of this application, please refer to Figures 1 to 9 As shown, the multi-wheel controllable warning cone includes a chassis 1 and a cone 2 mounted on the chassis 1;

[0034] Reference Figures 1 to 4 As shown, it also includes a fixed base 3, which is located below the chassis 1. The chassis 1 has a set of wheels at its bottom end, which allows the chassis 1 to move along the ground and to a position where it is aligned with the fixed base 3. Specifically, a servo motor a15 is located below the chassis 1. A latch plate 16 is connected to the drive shaft of the servo motor a15. When the chassis 1 moves to the position corresponding to the fixed base 3, the servo motor a15 is activated, and the latch plate 16 is lifted to fix the chassis 1 to the fixed base 3.

[0035] In this embodiment, a warning device is provided at the top of the cone 2 for warning purposes. It can be a strobe light or a reflective strip, and the warning object can be selected as needed. Specifically, the top of the cone 2 is fixed with a warning object by a buckle, thread, or bolt. The warning object is a strobe light, a reflective strip, or an LED warning light strip. The strobe light or LED warning light strip is electrically connected to the control module through wires. The reflective strip is fixed to the outer side of the cone 2 with adhesive. The control module can control the working status of the strobe light or LED warning light strip according to the wireless signal of the positioning module.

[0036] In this embodiment, the chassis 1 includes a housing 11 and a support base 12. The support base 12 is disposed on the upper end surface of the housing 11. The bottom end of the cone 2 is installed on the support base 12. When the chassis 1 moves along the ground via the wheel set, it can simultaneously drive the cone 2 to move synchronously to the place where a warning or alert is required. At this time, the warning device at the top of the cone 2 will perform the warning function.

[0037] In one feasible implementation, a positioning module is provided in the chassis 1 and / or the fixed base 3. The chassis 1 may also be provided with a control module. A wireless communication unit is provided between the positioning module and the control module. The positioning module can transmit position signals to the control module through the wireless communication unit, thereby controlling the traffic cone to move to the corresponding position. Specifically, if the positioning module is a UWB wireless communication positioning module, the UWB wireless communication positioning module includes a positioning tag and at least three positioning base stations. The positioning tag is fixedly pasted or installed on the side end face of the chassis 1 by fasteners. The positioning base stations are fixed to the upper end face of the fixed base 3 or the fixed structure around the working area of ​​the traffic cone by fasteners. The positioning tag is wirelessly adapted to the positioning base stations, and the positioning tag constitutes the signal transmitting end of the wireless communication unit. The control module is provided with a signal receiving end that is wirelessly adapted to the positioning tag.

[0038] The aforementioned wireless communication unit includes a Bluetooth module, a WiFi module, or a ZigBee module. The transmitting end of the Bluetooth module / WiFi module / ZigBee module is fixedly embedded in the housing of the positioning module, and the receiving end of the Bluetooth module / WiFi module / ZigBee module is fixedly embedded in the housing of the control module. The transmitting end and the receiving end are wirelessly connected.

[0039] Meanwhile, a camera can also be installed on the chassis 1. The camera is fixedly mounted on the upper surface of the chassis 1 by a mounting bracket. A servo motor is provided between the camera and the mounting bracket. The housing of the servo motor is fixed to the mounting bracket by bolts. The output shaft of the servo motor is fixedly connected to the housing of the camera. The camera and the servo motor are electrically connected to the control module through wires. The camera can transmit image signals to the control module through a wireless communication unit. The camera can be controlled to turn its angle by the servo motor. Position information can be obtained by taking pictures. Multi-directional scanning and positioning can be performed to facilitate accurate return of the equipment to its original position.

[0040] In this embodiment, refer to Figure 2 and Figure 3 As shown, the aforementioned wheel set includes at least two powered wheels 6 or at least two powered wheels 6 and one non-powered wheel 13. Specifically, at least two powered wheels 6 are arranged on the same side of the bottom end of the chassis 1, and the at least one non-powered wheel 13 is arranged on the opposite side of the bottom end of the chassis 1. The projections of at least two powered wheels 6 and at least one non-powered wheel 13 on the bottom end of the chassis 1 form a triangular support structure, which together constitutes a triangular force-bearing structure supporting the chassis 1 to improve the placement stability of the chassis 1.

[0041] Specifically, to increase the stability of the chassis 1, at least two driven wheels 6 are disposed on the same side of the bottom end of the chassis 1, and at least one non-driven wheel 13 is disposed on the opposite side of the bottom end of the chassis 1. At least one side of the non-driven wheel 13 is provided with an anti-tipping wheel 14. The non-driven wheel 13 and the driven wheel 6 are at the same height so that the chassis 1 remains horizontal when in contact with the ground or the fixed base 3. The height of the anti-tipping wheel 14 is lower than the height of the non-driven wheel 13 and the driven wheel 6, and when the chassis 1 is horizontal, there is a gap between the anti-tipping wheel 14 and the ground or the fixed base 3, that is, the anti-tipping wheel is suspended. When the chassis 1 tilts, the anti-tipping wheel 14 can contact the ground or the fixed base 3 to prevent tilting.

[0042] Reference Figure 8 , Figure 9 As shown, in order to increase the stability of the chassis 1, a wheel set can also be set to be embedded in the chassis 1. That is, unlike the wheel set located at the bottom of the chassis 1 in the above embodiment, the wheel set is partially located inside the chassis 1. Specifically, the non-powered wheel 13 and the powered wheel 6 are partially located outside the chassis 1 for contact with the ground. When the traffic cone moves, since the non-powered wheel 13 and the powered wheel 6 only partially protrude outside the chassis 1, the height of the chassis 1 from the ground is reduced, thereby reducing the risk of tipping over during movement.

[0043] In one possible application scenario, the traffic cone also includes a drive unit and a control unit. The drive unit and the control unit are connected by a mounting plate 5. Specifically, the drive unit includes a drive wheel 6, a drive motor 7, and a bracket 8. The drive motor 7 is mounted on the bracket 8, and the drive wheel 6 is connected to the drive motor 7 via the bracket 8. For example, the drive wheel 6 is connected to the drive shaft of the drive motor 7, and under the support of the bracket 8, the drive motor 7 can drive the drive wheel 6 to rotate, thereby moving the traffic cone. Specifically, for example, the drive motor 7 is electrically connected to the control module via a wire, and the control module can control the speed of the drive motor according to the wireless signal of the positioning module.

[0044] In this embodiment, the drive wheel 6 is provided with an axle, and the bracket 8 is provided with a hole through which the axle can pass. One end of the axle is connected to the drive motor 7, and the other end of the axle passes through the hole of the bracket 8 and is connected to the drive wheel 6. This not only transmits the driving force of the drive motor 7 to the drive wheel 6, but also fixes the bracket 8 and the drive wheel 6, so that the drive wheel 6 can rotate with the rotation of the bracket 8, thereby realizing the free movement of the traffic cone in all directions.

[0045] In the above possible implementation, the control unit includes a servo motor 9 and a gear set 10. The servo motor 9 is mounted on the end of the mounting plate 5. The servo motor 9 is connected to the bracket 8 through the gear set 10. Under the support of the mounting plate 5, the servo motor 9 can drive the bracket 8 to rotate through the gear set 10. In conjunction with the aforementioned drive wheel 6, since the drive wheel 6 is connected to the bracket 8, the movement trajectory of the drive wheel 6 can change with the rotation of the bracket 8, thereby enabling the free movement of the traffic cone.

[0046] Specifically, refer to Figure 7 As shown, the gear set 10 includes a driving gear 101 and a driven gear 102. The driving gear 101 is connected to the drive shaft of the servo motor 9. The driving gear 101 and the driven gear 102 mesh and drive each other. The driven gear 102 is connected to the bracket 8 through the mounting plate 5. A rotating shaft can be provided. One end of the rotating shaft is fixedly connected to the bracket 8, and the other end of the rotating shaft passes through the mounting plate 5 and is connected to the driven gear 102. Under the driving action of the servo motor 9, the driving gear 101 drives the driven gear 102 to rotate, which in turn drives the bracket 8 to rotate. Through the servo motor 9, the direction of the power wheel 6 can be changed.

[0047] In one feasible embodiment, the chassis 1 is also provided with a battery and a function box. The battery is used to provide electric drive power to the servo motor 9, the drive motor 7, and the servo motor a15. The function box is provided with a charging interface and a start switch. The charging interface is used to charge the battery, and the start switch can control whether the traffic cone is working.

[0048] In one feasible implementation, refer to Figure 6 As shown, the lower end of the chassis 1 is also equipped with a charging transmitter 17, a wireless transmitter 18 and a wireless receiver 19, which are used to control the road cone to charge when the battery is low or when it returns to the fixed base 3 after the work is completed.

[0049] In this embodiment, refer to Figure 5 As shown, an end plate 31 is provided on the end side of the fixed base 3, and an equipment end alignment hole 32 is provided on the end plate 31; an alignment base 111 and an equipment end alignment part 112 are provided at the lower end of the chassis 1. When the chassis 1 can move along the ground through the above-mentioned wheel set and can move to the returning state that aligns with the fixed base 3, the above-mentioned equipment end alignment part 112 aligns with the equipment end alignment hole 32.

[0050] A power supply 113 is also provided on the chassis 1. After the fixed base 3 is aligned and engaged with the chassis 1, the power supply 113 is located on the end plate 31 side near the fixed base 3, and is used to supply power to one or more of the charging transmitter 17, the wireless transmitter 18 and the wireless receiver 19.
