Description

Technical Field

[0001] This invention relates to the field of emergency rescue technology, specifically a road emergency rescue device. Background Technology

[0002] Roadside assistance refers to emergency roadside assistance for vehicles, providing on-site help to owners of disabled vehicles; it also refers to roadside assistance for traffic accidents, including treatment of the injured, traffic control, and emergency repairs.

[0003] During rescue operations, nighttime rescues are inevitable. When encountering mountain roads or construction roads in the wild without streetlights, it can cause difficulties for on-site rescue. Therefore, it is generally necessary to carry emergency rescue lights for illumination during rescue operations.

[0004] Currently, existing emergency lighting can be referenced in Chinese patent CN219264157U, which discloses a portable road rescue emergency light. This road rescue emergency light is foldable, which makes it more convenient for rescuers to use, saves their time, reduces their labor intensity, and facilitates subsequent rescue operations.

[0005] For example, Chinese patent CN118346935B discloses an emergency response mobile lighthouse device. This mobile lighthouse device has multiple battery chambers set in the mounting frame, so that the multiple battery modules in the lithium battery pack are independent of each other, reducing heat diffusion and avoiding heat conduction between them; at the same time, air is delivered from top to bottom in the air supply chamber for targeted air supply and heat dissipation, thereby improving the efficiency of the mobile lighthouse device.

[0006] The two types of emergency rescue lighting devices mentioned above are used for two purposes: firstly, to facilitate use by rescue personnel, and secondly, to provide ventilation and heat dissipation for the power supply battery modules while extending the lighting time. However, both types of emergency rescue lighting devices are more suitable for rescue in normal environments. In rainy or snowy weather, or in humid environments in the south, direct ventilation and heat dissipation can cause the humid air from the outside to come into direct contact with the batteries inside the mobile lighthouse, which may cause short circuits and other malfunctions, leading to power supply system failures and affecting the progress of on-site rescue or road clearing. Summary of the Invention

[0007] The purpose of this invention is to provide a road emergency rescue device to solve at least one technical problem existing in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a road emergency rescue device, comprising a mobile vehicle body, the mobile vehicle body including a telescopic arm capable of being raised, lowered, rotated, and adjusted, and a lighting lamp installed on the top of the telescopic arm, and further comprising:

[0011] A switching element is installed inside the partition, and the switching element can form an independent heat dissipation airflow between the two ventilation pipes and the battery box, and dissipate heat through indirect heat conduction to the battery via the switching element;

[0012] The regulating section is used to switch the heat dissipation airflow between the battery and two states: direct heat exchange and indirect heat conduction.

[0013] Preferably, a heat insulation plate is fixed in the middle of the battery box, and multiple partitions are installed on the inner walls of the battery box on both sides of the heat insulation plate, and the partitions and the heat insulation plate form a partition for separating the batteries.

[0014] Preferably, the battery box has partition cavities on both sides, and the inner walls of the partition cavities on both sides are provided with ventilation slots that communicate with the inside of the battery box. The switching component includes two adjusting bladders that are respectively fixed on both sides of the heat insulation plate. The middle of the adjusting bladder is provided with a partition layer that runs through it, and the outer side of the adjusting bladder away from the heat insulation cotton is provided with a heat-conducting layer.

[0015] The regulating bladder has two states: inflated and deflated. In the deflated state, the ventilation slot is directly connected to the inside of the battery box. In the inflated state, the partition layer wraps around the ventilation slot and forms an internal sealed channel.

[0016] Preferably, the inner walls of both sides of the battery box are fixed with side plates, and the outer walls of the side plates located between each partition are fixed with air exchange bladders. The air exchange bladders are also provided with a through gap in the middle. The air exchange bladders are provided with air inlets near the outer walls of the battery. The side plates are provided with diversion channels communicating with the partition cavity on one side. The part of the air exchange bladders near the side plates is provided with diversion holes communicating with the diversion channels, and the diversion holes are staggered from the air inlets.

[0017] Preferably, the adjusting part includes a second piston tube and a first piston tube fixed to the inner wall of the partition cavity, and the second piston tube corresponds to the side plate, the first piston tube corresponds to the heat insulation plate, a first piston rod is slidably installed on the inner wall of the first piston tube, a second piston rod is slidably installed on the inner wall of the second piston tube, a first air hole is opened in the interior of the heat insulation plate, and the first air hole communicates with the interior of the first piston tube, and a second air hole is opened in the interior of the side plate, and the second air hole communicates with the interior of the air exchange bag and the interior of the second piston tube;

[0018] The adjustment unit also includes a drive component that can drive the first piston rod and the second piston rod to slide and adjust in opposite directions.

[0019] Preferably, the driving component includes a rotating shaft rotatably mounted on the inner wall of the partition cavity, and a handle is installed at one end of the rotating shaft that protrudes from the outer wall of the battery box. A swing rod is fixed to the outer wall of the rotating shaft, and a slot is opened at one end of the swing rod. A pin is fixed to the outer wall of the second piston rod, which is inserted into the slot and slides in contact with the slot. The other end of the swing rod is provided as an elastic telescopic part, and one end of the elastic telescopic part is rotatably connected to the outer wall of the first piston rod.

[0020] Preferably, the air bladder is filled with elastic cotton or elastic fiber filaments.

[0021] Preferably, when the regulating bladder is inflated, its outer edge is tightly fitted to the battery, and it is fitted to the separator to keep the battery in a sealed space.

[0022] Preferably, a sealing strip is provided between the adjustment bag and the side wall contact surface of the battery box.

[0023] Preferably, the heat insulation board has internal reinforcing ribs, and the spaces between adjacent reinforcing ribs are perforated and filled with heat insulation cotton.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] When using this invention, due to different usage environments, there may be sunny days, rainy days, or snowy days and other severe weather. In sunny or dry weather, the ambient temperature is high and the air humidity is low. Therefore, the method of heat exchange through direct contact between the air and the battery can maximize the heat dissipation effect of the battery. Therefore, the adjustment unit switches to the method of heat dissipation airflow directly exchanging heat with the battery for heat dissipation. The external airflow enters the battery box from one of the ventilation pipes, passes through the gap between the partition and the battery, and is discharged from the other ventilation pipe, carrying away the heat generated by the battery and achieving the purpose of heat dissipation through direct heat exchange.

[0026] In severe weather conditions such as rain or snow, the ambient temperature is low and the air humidity is high. High humidity air is not suitable for direct heat exchange with the battery to avoid causing the battery to get damp. Therefore, the regulating unit switches to a method of heat dissipation through indirect heat conduction between the cooling airflow and the battery via switching components. That is, after the cooling airflow enters the battery box, it forms an independent cooling airflow flowing within the battery box between the switching components in the partition. This cooling airflow does not come into direct contact with the battery, but conducts heat to the battery through the switching components, and then the cooling airflow cools the switching components to achieve the purpose of indirect heat exchange.

[0027] In this way, by adjusting the battery's heat dissipation method according to the road emergency rescue environment, it can adapt to different usage environments and scenarios, thus reducing its limitations. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1 to 9 The present invention provides a technical solution: a road emergency rescue device, including a mobile vehicle body 1, the mobile vehicle body 1 including a telescopic arm 2 that can be raised, lowered, rotated and adjusted, and a lighting lamp 3 is installed on the top of the telescopic arm 2, and further including:

[0040] A battery box 4 is installed inside the mobile vehicle body 1. A removable cover 5 is installed on the top of the battery box 4. The interior of the battery box 4 is provided with partitions to separate the batteries 10 from each other.

[0041] Ventilation pipes 6 are connected to both sides of the battery box 4, and the ventilation pipes 6 are connected to an air pump or external air flow to form a heat dissipation airflow that can directly exchange heat between the battery 10 and the gap of the partition.

[0042] A switching element is installed inside the partition, and the switching element can form an independent heat dissipation airflow within the battery box 4 between the two ventilation pipes 6, and dissipate heat to the battery 10 indirectly through the switching element.

[0043] The regulating unit is used to switch the heat dissipation airflow between the battery 10 and the two states of direct heat exchange and indirect heat conduction.

[0044] When using this road emergency rescue device, the mobile vehicle 1 is moved to a position beside or in the middle of the road. The telescopic arm 2 raises the lighting lamp 3 to the lighting position to obtain the maximum lighting range. Then, the battery 10 supplies power to provide lighting for rescue. In general, when accidents or natural disasters cause road blockages (such as landslides, rockfalls, etc., and road clearing work is carried out after the road is blocked), the road clearing time is long, so the usage time of the lighting lamp 3 will also be extended. At present, in order to increase the lighting time of the lighting lamp 3, the battery 10 is usually increased to maintain a large capacity. Therefore, heat dissipation treatment of the battery 10 during use is necessary. Hence, the ventilation pipe 6 is set up to dissipate heat from the battery 10 in the battery box 4 through ventilation to ensure a good operating environment for the battery 10.

[0045] In actual use, due to different usage environments, there may be sunny days, rainy days, or snowy days and other severe weather. In sunny or dry weather, the ambient temperature is high and the air humidity is low. Therefore, the heat exchange method of direct contact between the air and the battery 10 can maximize the heat dissipation effect of the battery 10. Therefore, the adjustment unit switches to the method of direct heat exchange between the heat dissipation airflow and the battery 10 for heat dissipation. Specifically, the external airflow enters the battery box 4 from one of the ventilation pipes 6, passes through the gap between the partition and the battery 10, and is discharged from the other ventilation pipe 6, carrying away the heat generated by the battery 10 to achieve the purpose of direct heat exchange for heat dissipation. In addition, the ventilation pipe 6 is preferably connected to the airflow through a pump to ensure the flow of the heat dissipation airflow.

[0046] In severe weather conditions such as rain or snow, the ambient temperature is low and the air humidity is high. High humidity makes direct contact with the battery 10 for heat exchange unsuitable, as this could cause the battery 10 to become damp. Therefore, the regulating unit switches to a method of indirect heat transfer between the cooling airflow and the battery 10 via a switching element. Specifically, after the cooling airflow enters the battery box 4, it forms an independent cooling airflow within the battery box 4 between the switching elements in the partition. This cooling airflow does not directly contact the battery 10 but conducts heat to the battery 10 through the switching elements, and then cools the switching elements, thus achieving indirect heat exchange. This avoids direct contact between the humid air from the outside and the battery 10. Furthermore, although indirect heat exchange reduces heat dissipation efficiency, the relatively low ambient temperature, combined with the heat exchange of the battery box 4 itself, also helps to cool the battery 10, ensuring its normal operation within its suitable temperature range.

[0047] In this way, by adjusting the heat dissipation method of battery 10 according to the environment of road emergency rescue, it can adapt to different usage environments and scenarios, thus reducing its limitations.

[0048] In one preferred embodiment, a heat insulation plate 7 is fixed in the middle of the battery box 4, and multiple partitions 9 are installed on the inner walls of the battery box 4 on both sides of the heat insulation plate 7. The partitions 9 and the heat insulation plate 7 form a partition for separating the batteries 10.

[0049] Specifically, one method of partitioning is provided; please refer to [link / reference]. Figure 3-4 The heat insulation plate 7 and the separator 9 can be used to separate the battery 10, which can ensure the formation of heat dissipation channels and reduce the mutual influence between the batteries 10.

[0050] In one preferred embodiment, an implementation of the switching element is provided, as detailed in [reference needed]. Figure 6 and Figure 7;

[0051] The battery box 4 has partition cavities 14 on both sides, and the inner walls of the partition cavities 14 on both sides are provided with ventilation slots 21 that communicate with the inside of the battery box 4. The switching component includes two adjustment bladders 8 that are fixed on both sides of the heat insulation plate 7 respectively. The middle of the adjustment bladder 8 is provided with a through partition layer 25, and the outer side of the adjustment bladder 8 away from the heat insulation cotton 23 is provided with a heat-conducting layer.

[0052] The regulating bladder 8 has two states: inflated and deflated. In the deflated state, the ventilation slot 21 is directly connected to the inside of the battery box 4. In the inflated state, the partition layer 25 wraps the ventilation slot 21 and forms an internal sealed channel.

[0053] As can be seen from the above, the switching device is mainly used in situations of indirect heat dissipation, and its specific usage is as follows:

[0054] When the regulating bladder 8 is deflated, it will adhere to and stick tightly to the outer wall of the heat insulation plate 7, thereby exposing the ventilation slot 21 to the battery box 4, so that the airflow entering the ventilation pipe 6 can directly enter the battery box 4, thereby achieving the purpose of direct heat exchange for the battery 10.

[0055] When the regulating bladder 8 is inflated, it expands, forming a partition layer 25 in the middle. Furthermore, as the regulating bladder 8 expands, the partition layer 25 encompasses the ventilation slot 21. (See attached image) Figure 7 The channel formed by the separator layer 25 is used as an independent heat dissipation channel inside the battery box 4. This separates the heat dissipation airflow from the battery 10 inside the battery box 4. Then, heat exchange is carried out by the contact between the regulating bag 8 and the battery 10, thereby achieving the above-mentioned indirect heat dissipation purpose. The side of the regulating bag 8 that is in contact with the battery 10 is set as a heat-conducting layer to improve the heat conduction efficiency of the battery 10.

[0056] In this way, the cooling airflow can be switched between two modes by changing the two states of the switching element.

[0057] In one preferred embodiment, an air inlet is added to the gap between the battery 10 and the partition during the heat dissipation process of direct heat exchange to increase the flow range of the heat dissipation airflow.

[0058] Side plates 11 are fixed to the inner walls of both sides of the battery box 4, and air exchange bladders 12 are fixed to the outer walls of the side plates 11 located between each partition 9. A through gap is also provided in the middle of the air exchange bladder 12. An air inlet 13 is provided on the outer wall of the air exchange bladder 12 near the battery 10. A diversion channel 27 communicating with a side partition cavity 14 is provided inside the side plate 11. A diversion hole 28 communicating with the diversion channel 27 is provided on the part of the air exchange bladder 12 near the side plate 11, and the diversion hole 28 is staggered from the air inlet 13.

[0059] See details Figure 3 and Figure 4 During the process of direct heat exchange between the aforementioned cooling airflow and battery 10, the specific direction of airflow can be found in [reference needed]. Figure 4 In the direction of the arrow, during this process, the air bladder 12 on the outer wall of the side plate 11 is inflated and a gap is formed in the middle. Thus, when the ventilation pipe 6 allows the cooling airflow into the partition cavity 14, some of the airflow will pass through the diversion channel 27 and enter the diversion hole 28. Since the diversion hole 28 and the air inlet 13 are staggered, see [reference needed]. Figure 9 In this way, some airflow can enter the air inlet 13 through the diversion hole 28 and the gap, and then merge into the main airflow in the middle through the gap between the battery 10 and the separator 9. This diversion channel design can further improve the heat dissipation efficiency of the battery 10.

[0060] It is worth mentioning that the air exchange bladder 12 and the regulating bladder 8 can be configured in the same way and have the same expansion method. When the above-mentioned method of indirect heat exchange is switched to the regulating bladder 8, the regulating bladder 8 is in an inflated state, while the air exchange bladder 12 needs to be switched to a deflated state. In this way, the two sides of the gap of the air exchange bladder 12 will be tightly pressed together, thereby sealing the diversion hole 28 and the air inlet 13 to prevent the entry of outside humid air.

[0061] In one preferred embodiment, the adjustment unit includes a second piston tube 16 and a first piston tube 15 fixed to the inner wall of the partition cavity 14. The second piston tube 16 corresponds to the side plate 11, and the first piston tube 15 corresponds to the heat insulation plate 7. A first piston rod 17 is slidably installed on the inner wall of the first piston tube 15, and a second piston rod 18 is slidably installed on the inner wall of the second piston tube 16. A first air hole 24 is opened inside the heat insulation plate 7, and the first air hole 24 connects the adjustment bladder 8 with the inside of the first piston tube 15. A second air hole 26 is opened inside the side plate 11, and the second air hole 26 connects the air exchange bladder 12 with the inside of the second piston tube 16.

[0062] The adjustment unit also includes a drive component that can drive the first piston rod 17 and the second piston rod 18 to slide and adjust in opposite directions.

[0063] For details on the adjustment section, please refer to [link / reference]. Figure 3 and Figure 5As shown in the figure, each piston rod can slide up and down in the corresponding piston tube to inflate or depress the regulating bladder 8 or the air exchange bladder 12 through the first air hole 24 or the second air hole 26, so as to switch between the two states of the regulating bladder 8 or the air exchange bladder 12. As can be seen from the above, the switching between the two states of the regulating bladder 8 and the air exchange bladder 12 is opposite. That is, in the heat dissipation method of direct heat exchange, the regulating bladder 8 is in the state of sucking air and depressing, and the air exchange bladder 12 is in the state of inflating air. In the heat dissipation method of indirect heat exchange, the regulating bladder 8 is in the state of inflating air and the air exchange bladder 12 is in the state of sucking air and depressing air.

[0064] Therefore, by using a driving component to drive the first piston rod 17 and the second piston rod 18 to slide and adjust in opposite directions under different heat dissipation methods, the above-mentioned purpose can be achieved in conjunction with the corresponding piston tube.

[0065] In one preferred embodiment, an implementation of the driving component is provided;

[0066] The driving component includes a rotating shaft 22 rotatably mounted on the inner wall of the partition cavity 14, and a handle is installed at one end of the rotating shaft 22 that protrudes from the outer wall of the battery box 4. A swing rod 19 is fixed on the outer wall of the rotating shaft 22. A slot is opened at one end of the swing rod 19. A pin is fixed on the outer wall of the second piston rod 18, which is inserted into the slot and slides in contact with the slot. The other end of the swing rod 19 is provided as an elastic telescopic part 20, and one end of the elastic telescopic part 20 is rotatably connected to the outer wall of the first piston rod 17.

[0067] For details, please refer to [link / reference]. Figure 5 When switching between the two states, the rotating shaft 22 is rotated by turning the outer handle, which in turn drives the swing rod 19 to rotate. During its swing, the first piston rod 17 and the second piston rod 18 will slide in opposite or opposite directions, thereby completing the above-mentioned air exchange process in the piston tube.

[0068] The pin on the second piston rod 18 and the groove on the swing rod 19 are designed to prevent the swing rod 19 from getting stuck with the second piston rod 18, ensuring the completeness of its stroke. Similarly, the elastic telescopic part 20 can also prevent the swing rod 19 from getting stuck with the first piston rod 17. On the other hand, the elastic force of the elastic telescopic part 20 can also provide a limiting lock for the swing rod 19 after swinging, ensuring the stability of the first piston rod 17 and the second piston rod 18 after adjustment.

[0069] In one preferred embodiment, the air bladder 12 is filled with elastic cotton or elastic fiber filaments.

[0070] As described above, when the airbag 12 is in a deflated state after inhalation, filling it with elastic cotton or elastic limiting silk allows it to become deflated and rigid under low pressure or even vacuum conditions. This increases the protection of the battery 10. Especially during natural disasters such as landslides or rockfalls blocking roads and requiring clearing operations, other external factors (such as rolling stones) may impact and damage the lighting device's battery pack, leading to power supply system failure and affecting on-site rescue efforts. As aid or road clearing progresses, the current state of the airbag 12 is equivalent to adding another layer of protection to the inside of the battery box 4. Even if there is an external impact, the elastic cotton or elastic fiber inside the airbag 12 can further buffer the impact without leaking air. Specifically, it can be compared with the way tempered glass breaks, that is, the airbag 12 will not be directly penetrated, and it will act as a net for the impacting object. In addition, the deflated airbag 12 is farther away from the battery 10, so it can minimize the direct collision between external impacting objects and the battery 10, further improving the safety performance.

[0071] In one preferred embodiment, when the regulating bladder 8 is inflated, its outer edge is tightly fitted to the battery 10 and is fitted to the separator 9, thus placing the battery 10 within the formed sealed space.

[0072] As can be seen from the above, when the regulating bladder 8 is in the inflated state, its outer edge is tightly attached to the battery 10, which can improve the heat conduction efficiency of the battery 10. At the same time, the cooperation between it and the separator 9 can keep the battery 10 in the sealed space formed between the separator 9, the outer wall of the regulating bladder 8, the cover 5 and the air exchange bladder 12, thereby further isolating the battery 10 from the external humid environment.

[0073] In one preferred embodiment, a sealing strip is provided between the adjustment bladder 8 and the side wall contact surface of the battery box 4.

[0074] The sealing strip can further improve the isolation effect of the regulating bladder 8 on the battery box 4 when it is inflated, and further prevent heat dissipation airflow from entering the battery box 4.

[0075] In one preferred embodiment, the heat insulation plate 7 has reinforcing ribs inside, and the space between adjacent reinforcing ribs is perforated and the perforated space is filled with heat insulation cotton 23.

[0076] See Figure 8 The heat insulation plate 7 and the heat insulation cotton 23 can further separate the batteries 10 and prevent mutual interference between the batteries 10 on both sides.

[0077] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed directly based on existing technical knowledge without any doubt. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0078] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
