Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically a robot base for multi-terrain applications. Background Technology

[0002] Because fire scenes typically present various safety hazards and are often accompanied by large amounts of dense smoke, the personal safety of firefighters cannot be guaranteed. Therefore, many types of firefighting robots have emerged on the market. Firefighting robots are a type of specialized robot, playing an increasingly crucial role in firefighting and rescue operations.

[0003] Firefighting robots, as specialized firefighting equipment, can replace firefighters in approaching fire scenes to carry out effective firefighting and rescue operations, chemical testing, and fire scene reconnaissance. However, disaster scenes are complex, and early robots mostly adopted fixed wheeled or tracked designs (such as Mars rovers and industrial AGVs). Although they are efficient on flat terrain, they are prone to slipping or getting stuck when encountering complex terrains such as sand, gravel, or steep slopes, making it difficult to cross and forcing them to detour, which seriously affects the progress of fire rescue. Utility Model Content

[0004] The purpose of this invention is to provide a robot base for multi-terrain applications, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a robot base for multi-terrain applications, comprising a base body and walking and climbing components mounted on the base body.

[0006] The walking component is installed below the base body, and the climbing component is located on the side of the base body. The climbing component includes a pressing component and a supporting component. The pressing component is installed on the base body, and the climbing component is installed at the end of the pressing component. The walking component enables the firefighting robot to walk, and the climbing component enables the base body to climb. The pressing component drives the supporting component to press down, supporting one side of the base body to enable the base body to climb.

[0007] In a preferred embodiment of this invention, the walking assembly includes a drive base and four triangular track wheels driven by the drive base, each located on a side of the drive base. The drive base drives the triangular track wheels, enabling all-terrain off-road travel and movement. This is suitable for mud, snow, swamps, rocky terrain, and uneven hilly surfaces. The drive base transmits power from the engine or motor to the drive wheels, coordinating the speed and torque of each track in a multi-track system. This helps maintain balance when adapting to complex terrain. The drive base is four-wheel drive.

[0008] As a preferred embodiment of this invention, the surface of the triangular track wheel is provided with anti-slip protrusions. These anti-slip protrusions are trapezoidal. The trapezoidal anti-slip protrusions are primarily used to improve the anti-slip effect.

[0009] As a preferred embodiment of this invention, the base body has a mounting groove on its side. The mounting groove is used to install climbing components.

[0010] In a preferred embodiment of this invention, the pressing assembly includes a hinged seat, a rotating shaft, a connecting arm, and a drive motor. The hinged seat is fixed in the mounting groove by bolts, the rotating shaft is hinged within the hinged seat, the connecting arm is fixed to the rotating shaft, and the drive motor is fixed to the side of the hinged seat. The drive shaft of the drive motor is connected to the rotating shaft. The drive motor drives the rotating shaft to rotate, which in turn drives the connecting arm to rotate up and down, thereby lowering the support assembly and supporting the base body.

[0011] In a preferred embodiment of this invention, the support assembly includes a telescopic motor, a roller seat, and a rotating roller. The telescopic motor is fixed to the end of the connecting arm, the roller seat is fixed to the output end of the telescopic motor, and the rotating roller is rotatably connected to the inner side of the roller seat. The length of the support assembly can be adjusted by the telescopic motor, which, in conjunction with the pressing component, drives the support assembly to descend, causing the rotating roller to contact the ground, thus supporting the base body. The drive base, drive motor, and telescopic motor are all controlled and driven by the overall control system.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention employs triangular tracked wheels as the walking component, combined with trapezoidal anti-slip protrusions on their surface, effectively handling complex terrains such as mud, snow, swamps, rocky ground, and uneven hills, ensuring stable robot movement in diverse environments. The climbing component, through the cooperation of the pressing and supporting components, can lift one side of the base, giving the robot a certain climbing ability and expanding its operating range on terrains with elevation differences (such as steps and slopes). The walking and climbing components have clearly defined roles yet work together; the walking component ensures basic movement, while the climbing component overcomes the limitations of ordinary walking in complex terrain, jointly enabling the robot to operate efficiently in various terrain environments.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a robot base for multi-terrain applications, including a base body 1 and a walking component 2 and a climbing component disposed on the base body 1.

[0019] The walking component 2 is installed below the base body 1, and the climbing component is located on the side of the base body 1. The climbing component includes a pressing component 3 and a supporting component 4. The pressing component 3 is installed on the base body 1, and the climbing component is installed at the end of the pressing component 3. The walking component 2 enables the firefighting robot to walk, and the climbing component enables the base body 1 to climb. The pressing component 3 drives the supporting component 4 to press down, supporting one side of the base body 1 to enable the base body 1 to climb.

[0020] Furthermore, the walking assembly 2 includes a drive base 201 and four triangular track wheels 202 driven by the drive base 201. The four triangular track wheels 202 are located on the sides of the drive base 201. The drive base 201 drives the triangular track wheels 202 for movement, enabling all-terrain off-road travel. This is suitable for mud, snow, swamps, rocky terrain, and uneven hilly surfaces. The drive base 201 transmits power from the engine or electric motor to the drive wheels, coordinating the speed and torque of each track in the multi-track system. This helps maintain balance when adapting to complex terrain. The drive base 201 is a four-wheel drive system, and the drive base driving the triangular track wheels is a mature existing technology; therefore, it will not be described in detail here.

[0021] Furthermore, the surface of the triangular track wheel 202 is provided with anti-slip protrusions 2021. The anti-slip protrusions 2021 are trapezoidal. The trapezoidal anti-slip protrusions 2021 are mainly used to improve the anti-slip effect.

[0022] Furthermore, a mounting groove 101 is provided on the side of the base body 1. The mounting groove 101 is used to install the climbing component.

[0023] Furthermore, the pressing assembly 3 includes a hinge base 301, a rotating shaft 302, a connecting arm 303, and a drive motor 304. The hinge base 301 is fixed in the mounting groove 101 by bolts. The rotating shaft 302 is hinged in the hinge base 301. The connecting arm 303 is fixed on the rotating shaft 302. The drive motor 304 is fixed to the side of the hinge base 301, and the drive shaft of the drive motor 304 is connected to the rotating shaft 302. The drive motor 304 drives the rotating shaft 302 to rotate, which in turn drives the connecting arm 303 to rotate up and down, thereby lowering the support assembly 4 and supporting the base body 1.

[0024] Furthermore, the support assembly 4 includes a telescopic motor 401, a roller seat 402, and a rotating roller 403. The telescopic motor 401 is fixed to the end of the connecting arm 303, the roller seat 402 is fixed to the output end of the telescopic motor 401, and the rotating roller 403 is rotatably connected to the inner side of the roller seat 402. The length of the support assembly 4 can be adjusted by the telescopic motor 401, which, in conjunction with the pressing component 3, drives the support assembly 4 to descend, and the rotating roller 403 contacts the ground to support the base body 1. The drive base 201, drive motor 304, and telescopic motor 401 are all controlled and driven by the overall control system.

[0025] In summary, the drive base 201 in the walking assembly 2 transmits power from the engine or motor to the four triangular track wheels 202. By coordinating the rotational speed and torque of each track, the triangular track wheels 202 are driven to rotate, enabling the robot to walk on various terrains (such as mud, snow, swamp, rocky ground, and uneven hills). Simultaneously, the trapezoidal anti-slip protrusions 2021 on the surface of the triangular track wheels 202 enhance friction with the ground, improving walking stability. When climbing is required, the climbing assembly comes into play. First, the drive motor 304 in the pressing assembly 3 drives the rotating shaft 302 to rotate, which in turn drives the connecting arm 303 to rotate up and down, causing the support assembly 4 to descend. Subsequently, the telescopic motor 401 of the support assembly 4 adjusts its length, coordinating with the action of the pressing assembly 3, to bring the rotating roller 403 into contact with the ground. Finally, through the coordinated action of the pressing assembly 3 and the support assembly 4, one side of the base body 1 is lifted, achieving the climbing action. The mounting groove 101 on the side of the base body 1 provides a stable mounting position for the climbing component, ensuring the structural stability during the climbing process.

[0026] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
