[0001] The present invention relates to the technical fields of vehicle handling and fire prevention, and particularly to a composite mobile robot for automatically moving new energy vehicles and isolating the fire source. Background Art

[0002] With the rapid development of society today, the car ownership has greatly increased, and the parking spaces in underground parking lots are often in short supply. People often park their cars randomly, blocking the driving lanes or pedestrian passages, resulting in traffic jams. With the rapid development of new energy vehicles, the potential safety hazards in the parking environment have received increasing attention. Especially in the context of the popularization of electric vehicles, the risk of safety accidents such as battery fires is higher, which makes it particularly important to apply fire prevention robots in parking lots and other places.

[0003] New energy vehicles, especially pure electric vehicles, widely use lithium-ion batteries, which have the risks of fire and explosion during charging and use. According to statistical data, the fire incidents caused by lithium battery failures are more complex and dangerous than those of traditional fuel vehicles. Such fires are often caused by factors such as battery short circuits and battery thermal runaway, and the fire spreads rapidly and is difficult to extinguish. Therefore, in the parking lots and charging facilities of new energy vehicles, fire prevention and the transfer of the vehicle on fire are crucial. A composite mobile robot for automatically moving new energy vehicles and isolating the fire source can effectively respond to the scenario of a car fire in a densely parked area. Summary of the Invention

[0004] In view of the above problems, the present invention provides a composite mobile robot for automatically moving new energy vehicles and isolating the fire source.

Detailed Description of the Invention

[0040] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

Moreover, the term "comprising", "including" or any other variation thereof is intended to cover a non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, the elements defined by the statement "comprising..." do not exclude the presence of additional identical elements in the process, method, article or device comprising the said elements. If there is no conflict, the embodiments of the present invention and the various features in the embodiments may be combined with each other, and all are within the protection scope of the present invention.

[0042] The rapid development of contemporary society and the urbanization process have brought many conveniences, but a series of challenges that follow cannot be ignored. One of them is the parking safety problem caused by the rapid growth in the number of new energy vehicles. With the popularization of electric vehicles, especially new energy vehicles using lithium-ion batteries, their fire hazards have gradually become a major problem in public safety management. Especially in high-density areas such as urban underground parking lots and charging stations, once a battery fire occurs, it often spreads rapidly, resulting in extremely serious consequences.

[0043] Currently, in the face of the fire risk of new energy vehicles, traditional fire prevention measures mainly rely on fire-fighting equipment and manual inspections. Parking lots are usually equipped with equipment such as fire extinguishers, smoke detectors, and automatic sprinkler systems. However, these devices cannot respond promptly to sudden fires and cannot handle problems quickly and effectively in the initial stage of a fire. In addition, since new energy vehicles usually adopt relatively complex battery systems, once a fire occurs, it is more difficult to extinguish than traditional fuel vehicles, and the fire spreads relatively fast. Timely vehicle relocation measures often need to be taken to prevent the fire from spreading to other vehicles or areas.

[0044] To address this issue, engineers and technical experts have developed a composite mobile robot for automatic vehicle relocation and fire source isolation of new energy vehicles. This robot can not only isolate vehicles with fire hazards but also quickly move the fire-source vehicle to a safe area in the first place to prevent the fire from spreading. This innovative design enables the robot to have stronger emergency response capabilities, quickly respond to the occurrence of electric vehicle fires, and prevent the fire from spreading to other vehicles or parking areas.

[0045] For the above technical problems, please refer to Figures 1 to 9 , an embodiment of the present invention provides a composite mobile robot for automatic vehicle relocation and fire source isolation of new energy vehicles, which is applied to vehicles and includes 1 - a mobile platform, 2 - a lifting mechanism, 3 - a side expansion and telescopic mechanism, and 4 - a fire curtain deployment mechanism.

[0046] 1 - The mobile platform includes: Mecanum wheels (101); a platform housing (102);

[0047] The composite mobile robot for automatic vehicle relocation and fire source isolation of new energy vehicles provided by the present invention, by setting the Mecanum wheel mechanism, as shown in Figure 2 , realizes that the robot can freely move in any direction by adjusting the rotation speeds of each Mecanum wheel on a plane without changing the vehicle body direction, greatly improving the flexibility of the robot and enabling it to handle vehicles in different parking poses.

[0048] 2 - The lifting mechanism includes:

[0049] Lifting base (201), the lifting base (201) is installed on the platform housing (102) to serve as the base of the lifting mechanism; Scissor link mechanism (202), the scissor link mechanism (202) is arranged on the side of the lifting base (201) to serve as the support of the lifting mechanism; Ball screw mechanism (204), the ball screw mechanism (204) is arranged at two intersecting nodes of the links of the scissor link mechanism (202), and the ball screw mechanism can make the two nodes approach or move away from each other in the first direction X, so that the lifting base (201) and the lifting top plate (205) approach or move away from each other in the third direction Z; Driving motor (203), the driving motor (203) is fixedly installed at the end of the ball screw mechanism (204) to provide driving force for the lifting mechanism; Lifting top plate (205), the lifting top plate (205) is arranged on the scissor link mechanism (202) to serve as the platform connected to the vehicle chassis.

[0050] By setting the lifting mechanism (2), such as Figure 3 As shown, the composite mobile robot for automatic vehicle moving and fire source isolation of new energy vehicles can meet the handling requirements of vehicles with different chassis heights. For example, in an underground parking lot, when it is necessary to move a SUV and a sedan, the difference in their chassis heights is obvious. Through the adjustment of the lifting mechanism (2), the robot can adaptively adjust the lifting amplitude according to the chassis height of each vehicle, so as to ensure that it can stably and safely move vehicles with various chassis heights.

[0051] To facilitate the understanding of the structure of the composite mobile robot for automatic vehicle moving and fire source isolation of new energy vehicles, the following further describes some structures of the lifting mechanism:

[0052] In some embodiments, the driving motor (203) is a servo motor.

[0053] A servo motor is a motor that can precisely control the angle, speed and position, has a high torque output, can provide a large torque at a low speed, and can withstand the change of load and maintain stable operation.

[0054] The servo motor is installed at Figure 4 the end of the ball screw mechanism shown as the driving mechanism.

[0055] The ball screw mechanism is a known structural design method in the art and is widely used in occasions requiring high performance and precision. The ball screw can withstand a large axial load and has good stability. Under the condition of bearing a high load, it can still maintain good operating performance.

[0056] In the embodiment, the driving motor (203) can also be other motors, etc. The present invention is not limited thereto and can be adjusted according to requirements.

[0057] The 3-side expansion and telescopic mechanism includes:

[0058] The first link fixing member (301) is fixedly installed on the moving platform (1) and serves as the fixing mechanism of the side expansion and telescopic mechanism (3); the driving motor (302) is arranged on the first link fixing member (301) and serves as the driving force source of the side expansion and telescopic mechanism (3); the first side expansion link (303) is connected to the driving motor (302) through the first link fixing member (301) and serves as the driven member; the torsion spring member (304) is arranged between the first side expansion link (303) and the second side expansion link (305), so that when the first side expansion link (303) is driven by the driving motor (302), it drives the second side expansion link (305) to move together, so as to drive the side expansion and telescopic mechanism to extend or contract along the second direction Y; the second side expansion link (305) is connected to the first side expansion link (303); the second link fixing member (306) is connected to the second side expansion link (305); the end bearing flat plate (307) is connected to the second link fixing member and serves as the bearing platform of the fire curtain unfolding mechanism (4), playing a fixing role.

[0059] By setting the side expansion and telescopic mechanism, such as Figure 5 As shown, the composite mobile robot for automatic parking and fire source isolation of new energy vehicles can adapt to vehicles with different vehicle widths. When the composite mobile robot for automatic parking and fire source isolation of new energy vehicles moves under the vehicle chassis and jacks up the vehicle to be moved, the side expansion and telescopic mechanism expands along the second direction Y on the side. During the expansion process, the driving motor (302) provides the driving force, rotates the first side expansion link (303) in the direction away from the side of the moving platform, and the second side expansion link (305) is constrained by the first side expansion link (303) and the torsion spring member (304), so that the second side expansion link (305) expands in coordination with the first side expansion link (303), making the end bearing flat plate (307) far away from the side of the moving platform and extending out of the side of the vehicle to be moved.

[0060] The 4-fire curtain unfolding mechanism includes:

[0061] The first fire curtain storage box (401), the first fire curtain storage box (401) is installed on the end bearing flat plate (307), serving as a storage box for the fire curtain, and is equipped with a driving motor (413) for storing the first fire curtain (406); the first connecting rod fixing member (402), the first connecting rod fixing member (402) is installed on the first fire curtain storage box (401), serving as a fixing member for the first connecting rod (403); the first connecting rod (403), the first connecting rod (403) is arranged on the first connecting rod fixing member (402) and is driven by a driving motor (414); the second connecting rod (404), the second connecting rod (404) is connected to the first connecting rod (403); the second connecting rod fixing member (408), the second connecting rod fixing member (408) is connected to the end of the second connecting rod (404); the end bearing plate (409), the end bearing plate (409) is fixedly connected to the second connecting rod fixing member (408), serving as a fixing platform for the passive telescopic sleeve (412).

[0062] In addition, it also includes the unfolding part of the second fire curtain, including:

[0063] The spiral bevel gear reducer (411), the spiral bevel gear reducer (411) is fixed on the side surface of the first fire curtain storage box (401) in the second direction Y; the ball screw mechanism (412), the ball screw mechanism (412) is connected to the output end of the spiral bevel gear reducer (411) and is powered by the spiral bevel gear reducer (411); the second fire curtain storage box (405), the second fire curtain storage box (405) is fixedly connected to the slider of the ball screw mechanism (412) and is driven by the ball screw mechanism (412) to move closer to or away from the spiral bevel gear reducer (411) in the first direction X; the second fire curtain (407), the second fire curtain (407) is stored in the second fire curtain storage box (405); the passive telescopic sleeve (412), the passive telescopic sleeve (412) is fixed on the end bearing plate (409) and is connected to the second fire curtain storage box (405) through the second fire curtain (407). When the second fire curtain storage box (405) moves closer to or away from the spiral bevel gear reducer (411) in the first direction X under the drive of the ball screw mechanism (412), the passive telescopic sleeve (412) is driven accordingly; the second driving motor (410), the second driving motor (410) is fixed at the power input end of the spiral bevel gear reducer (411), serving as the power input of the spiral bevel gear reducer (411); the driving motor (413), the driving motor (413) serves as the storage power source of the second fire curtain (407).

[0064] By setting the fire curtain unfolding mechanism, such as Figures 6 to 9As shown, the composite mobile robot for automatic parking and fire source isolation of new energy vehicles can deploy a fireproof curtain in the third direction. The coverage range of the fireproof curtain can be adjusted through the fireproof curtain deployment mechanism. The height of the fireproof curtain in the third direction Z can be controlled and adjusted through the first link (403) and the second link (404). The width in the first direction X can be controlled and adjusted through the ball screw mechanism (411) and the second fireproof curtain storage box (405). Through this fireproof curtain deployment mechanism, vehicles of different lengths can be dealt with to achieve the lateral enclosure of the burning vehicle.

[0065] To facilitate the understanding of the structure of the composite mobile robot for automatic parking and fire source isolation of new energy vehicles, some structures of the fireproof curtain deployment mechanism are further described as follows:

[0066] First, in the first direction X, the fireproof curtain deployment mechanism unfolds the second fireproof curtain storage box (405) through the ball screw mechanism as Figure 8 shown. The drive of the ball screw mechanism is driven by the second drive motor (410), and the power is distributed to both ends of the ball screw mechanism through the spiral bevel gear reducer (411). The passive telescopic sleeve (412) is as Figure 9 shown, and its power is provided by the fireproof curtain and the second fireproof curtain storage box (405), and it unfolds synchronously with the second fireproof curtain storage box (405) until it reaches the front and rear of the vehicle to be moved.

[0067] Then, in the third direction Z, the fireproof curtain deployment mechanism drives the first link (403) and the second link (404) to unfold through the drive motor (413) until the fireproof curtain covers the top of the vehicle to be moved.

[0068] The deployment working state of the composite mobile robot for automatic parking and fire source isolation of new energy vehicles of the present invention and the application vehicle are as Figure 10 shown.

[0069] The usage method and working process of the composite mobile robot for automatic parking and fire source isolation of new energy vehicles of the present invention are as Figure 11 shown.
