[0045] Referring to Figures 1 to 3 , in a first aspect of the present utility model, a lighting device 30 is provided. The lighting device 30 includes a base 100 and at least one set of lighting devices 200. The base 100 is provided on the boom assembly 20 of a fire truck; the lighting device 200 includes a first-stage link assembly 210, a second-stage link assembly 220, and a lighting lamp 300. The first-stage link assembly 210 is provided on the base 100, and the second-stage link assembly 220 is also provided on the base 100. The second-stage link assembly 220 is also connected to the first-stage link assembly 210 at the same time. The second-stage link assembly 220 has a deployed state and a retracted state, and is adapted to rotate relative to the base 100 under the drive of the first-stage link assembly 210; the lighting lamp 300 is provided at one end of the second-stage link assembly 220 away from the base 100, and the lighting lamp 300 is adapted to be switched between a retracted position and a deployed position under the drive of the second-stage link assembly 220.

[0046] Specifically, taking Figure 2 and Figure 3 as examples, the retracted position refers to the position of the lighting lamp 300 in the non-operating state, that is, the position of the lighting lamp 300 shown in Figure 2 . When the lighting lamp 300 is in the retracted position, the second-stage link assembly 220 is in the retracted state; the deployed position refers to the position of the lighting lamp 300 when the operation requirements are met, that is, the position of the lighting lamp 300 shown in Figure 3 . When the lighting lamp 300 is in the deployed position, the second-stage link assembly 220 is in the deployed state; it should be noted that the retracted position and the deployed position are not limited to the positions of the lighting lamp 300 in Figure 2 and Figure 3 . The specific positions of the retracted position and the deployed position can be adaptively designed according to the actual situation to meet the actual needs.

[0047] Referring to Figures 1 to 3 , it can be understood that for the lighting device 30 provided in the embodiment of the present utility model, by providing the first-stage link assembly 210 and the second-stage link assembly 220 on the base 100, and setting the lighting lamp 300 on the second-stage link assembly 220, in this way, under the drive of the first-stage link assembly 210, the second-stage link assembly 220 can rotate relative to the base 100. Based on this, when the second-stage link assembly 220 is deployed or retracted, the lighting lamp 300 can be switched between the retracted position and the deployed position under the drive of the second-stage link assembly 220. In this way, the expansion of the lighting lamp 300 and the multi-angle direction adjustment can be realized, that is, the switching of the lighting lamp 300 between the operating state and the non-operating state can be realized.

[0048] Compared with the prior art, the lighting device 30 provided by the embodiment of the present utility model drives the lighting lamp 300 to switch between a retracted position and an extended position by arranging a first-stage link assembly 210 and a second-stage link assembly 220 on the base 100. In this way, on the one hand, the limitation of the position of the lighting lamp 300 by the base 100 in the prior art can be broken, and the lighting range of the lighting lamp 300 can be expanded; on the other hand, when the second-stage link assembly 220 is in a retracted state, the volume of the lighting device 30 can be greatly reduced, the space occupied by the lighting device 30 can be reduced, and the requirement for the installation space of the lighting device 30 can be lowered; in addition, both the first-stage link assembly 210 and the second-stage link assembly 220 are link structures, and the link structures are light in texture, which can reduce the overall mass of the lighting device 30. On the one hand, it is beneficial to assembly and transportation, and on the other hand, it can reduce consumables and lower costs.

[0049] Figure 4 It is a schematic diagram of the detailed structure of the second-stage link assembly provided by the embodiment of the present utility model.

[0050] Refer to Figure 4 In an alternative embodiment of the present utility model, the second-stage link assembly 220 includes a second-stage link base 221, a link member 222, a second-stage driving cylinder 223, and a lighting lamp bracket 224. The second-stage link base 221 is rotatably arranged on the base 100 and is connected to the first-stage link assembly 210. The second-stage link base 221 is adapted to rotate relative to the base 100 under the drive of the first-stage link assembly 210; the link member 222 has an extended state and a retracted state and is hinged to the first end of the second-stage link base 221.

[0051] One end of the second-stage driving cylinder 223 is hinged to the second end of the second-stage link base 221, and the other end is hinged to the link member 222. The second-stage driving cylinder 223 is used to drive the link member 222 to switch between the extended state and the retracted state. The second-stage driving cylinder 223 can adopt a linear motion device such as an electric push cylinder or a hydraulic cylinder; the lighting lamp bracket 224 is hinged to the end of the link member 222 away from the second-stage link base 221, and the lighting lamp 300 is arranged on the lighting lamp bracket 224.

[0052] It can be understood that in the embodiment of the present utility model, by arranging the second-stage driving cylinder 223 and the link member 222, when the second-stage driving cylinder 223 pushes the link member 222 to expand, the lighting lamp bracket 224 connected to the link member 222 will expand outward synchronously. Since the lighting lamp 300 is arranged on the lighting lamp bracket 224, the expansion of the lighting lamp 300 can be realized. Based on the cooperation with the aforementioned first-stage link assembly 210, the switching of the lighting lamp 300 between the retracted position and the extended position can be simply realized.

[0053] Continue to refer to Figure 4, in an alternative embodiment of the present utility model, the connecting rod component 222 includes a first flipping connecting rod 2221, a second flipping connecting rod 2222, a third flipping connecting rod 2223, and an extension connecting rod 2224. One end of the first flipping connecting rod 2221 is hinged to the first end of the secondary connecting rod base 221, and the other end is hinged to the second flipping connecting rod 2222. The end of the second flipping connecting rod 2222 away from the first flipping connecting rod 2221 is hinged to the third flipping connecting rod 2223. The end of the third flipping connecting rod 2223 away from the second flipping connecting rod 2222 is hinged to the lighting lamp bracket 224. One end of the extension connecting rod 2224 is hinged to the first end of the secondary connecting rod base 221, and the other end is hinged to the lighting lamp bracket 224. At the same time, the secondary driving cylinder 223 is hinged to the extension connecting rod 2224, and the second flipping connecting rod 2222 is also hinged to the extension connecting rod 2224.

[0054] Specifically, when the secondary driving cylinder 223 drives the extension connecting rod 2224 to expand, the second flipping connecting rod 2222 moves accordingly. When the second flipping connecting rod 2222 moves with the extension connecting rod 2224, the first flipping connecting rod 2221 will limit the moving direction of the second flipping connecting rod 2222, so that the second flipping connecting rod 2222 rotates relative to the extension connecting rod 2224. When the second flipping connecting rod 2222 rotates, the third flipping connecting rod 2223 can drive the lighting lamp bracket 224 to rotate relative to the extension connecting rod 2224. It is easy to understand that during this process, the lighting lamp bracket 224 has two movements. One is the outward expansion of the lighting lamp bracket 224 relative to the secondary connecting rod assembly 220, and the other is the rotation of the lighting lamp bracket 224 relative to the extension bracket. This rotation can be used to realize the flipping of the lighting lamp 300.

[0055] Refer to Figures 1 to 4 , it can be understood that in the embodiment of the present utility model, by providing the first flipping connecting rod 2221, the second flipping connecting rod 2222, the third flipping connecting rod 2223, and the extension connecting rod 2224, in this way, under the driving action of the secondary driving cylinder 223, the outward expansion movement of the lighting lamp bracket 224 and the flipping movement relative to the extension connecting rod 2224 can be simply realized. Further, combined with the rotation of the secondary connecting rod assembly 220 relative to the base 100 driven by the primary connecting rod assembly 210, the switching between the retracted position and the deployed position of the lighting lamp 300 can be realized. Such a setting, compared with the prior art, can not only realize the expansion and flipping of the lighting lamp 300, but also achieve a larger lighting range in the same installation space. And when in the non-operating state, this setting can also retract the lighting lamp 300 to avoid damage to the lighting lamp 300. In addition, the connection of each component in the connecting rod component 222 is simple and direct, easy to assemble, and is conducive to mass production and use.

[0056] Continue to refer to Figure 1, in an alternative embodiment of the present utility model, the primary link assembly 210 includes a primary drive cylinder 211 and a rotating member 212. The first end of the primary drive cylinder 211 is hinged to the base 100, the second end of the primary drive cylinder 211 is hinged to the rotating member 212, the first end of the rotating member 212 is rotatably connected to the base 100, and the second end of the rotating member 212 is rotatably connected to the secondary link assembly 220. The rotating member 212 is adapted to drive the secondary link assembly 220 to rotate under the drive of the primary drive cylinder 211. The primary drive cylinder 211 can adopt a linear motion device such as an electric push cylinder or a hydraulic cylinder. Specifically, it can be adaptively selected according to the actual situation. It can be understood that the primary drive cylinder 211 and the rotating member 212 are easily obtained and have a simple structure. By setting the primary drive cylinder 211 to drive the rotating member 212 to drive the secondary link assembly 220 to rotate, on the one hand, the overall production cost of the lighting device 30 can be reduced, and on the other hand, the assembly difficulty can be reduced and the assembly efficiency can be improved.

[0057] Figure 5 is a schematic diagram of the detailed structure of the base provided by the embodiment of the present utility model.

[0058] Continue to refer to Figure 1 and Figure 5 , in an alternative embodiment of the present utility model, the base 100 includes a bottom plate 110 and a side plate 120. The bottom plate 110 and the side plate 120 are fixedly connected. The secondary link assembly 220 is disposed on the side of the side plate 120 away from the bottom plate 110. The first end of the primary drive cylinder 211 is hinged to the bottom plate 110, the first end of the rotating member 212 is rotatably connected to the side plate 120, and the second end of the rotating member 212 passes through the side plate 120 and is rotatably connected to the secondary link assembly 220. The bottom plate 110 is used for assembling with the boom assembly 20. It can be understood that by setting the bottom plate 110 and the side plate 120, the movement of the primary link assembly 210 and the secondary link assembly 220 can be prevented from interfering with the boom assembly 20, and the stable operation of the lighting device 30 can be ensured.

[0059] Continue to refer to Figure 1 , in an alternative embodiment of the present utility model, the primary link assembly 210 further includes a rotating shaft 213. The rotating shaft 213 passes through the secondary link base 221 of the rotating member 212, the side plate 120, and the secondary link assembly 220. It can be understood that since the rotating member 212 and the secondary link assembly 220 are coaxial through the rotating shaft 213, in this way, when the second end of the rotating member 212 drives the secondary link assembly 220 to rotate, the rotating member 212 and the secondary link assembly 220 will maintain synchronous and coaxial rotation. In this way, on the one hand, it can facilitate the precise control of the rotation angle of the secondary link assembly 220, and on the other hand, it can improve the stability of the primary link assembly 210 and the secondary link assembly 220.

[0060] Continue to refer toFigure 5 In an alternative embodiment of the present utility model, a kidney-shaped hole 130 is provided on the side plate 120. The second end of the rotating member 212 is adapted to pass through the kidney-shaped hole 130 and is rotatably connected to the secondary link assembly 220. The size and the setting direction of the kidney-shaped hole 130 can be adaptively set according to the actual situation. It can be understood that the kidney-shaped hole 130 can limit the movement path of the connecting shaft between the second end of the rotating member 212 and the secondary link assembly 220. Based on this, the rotation paths and the rotation directions of the secondary link assembly 220 and the rotating member 212 can be limited.

[0061] Continue to refer to Figures 1 to 3 In an alternative embodiment of the present utility model, there are two lighting devices 200. One of the two lighting devices 200 is provided on one side of the base 100, and the other one of the two lighting devices 200 is provided on the other side of the base 100. It should be noted that the two lighting devices 200 can be symmetrically arranged along the midline of the base 100 or can be asymmetrically arranged. Specifically, it can be adaptively selected according to the actual situation. It can be understood that by providing the two lighting devices 200, lighting can be carried out separately from both sides of the base 100. In this way, not only can the lighting range of the lighting device 30 be increased, but also the uniformity of the light-receiving areas on both sides of the base 100 can be improved, which is beneficial for firefighters to identify and judge the on-site situation.

[0063] Refer to Figures 6 to 9 In the second aspect of the present utility model, a fire truck is provided. The fire truck includes a vehicle body 10, a boom assembly 20, and the lighting device 30 according to any one of the foregoing embodiments. The boom assembly 20 is provided on the top surface of the vehicle body 10, and the lighting device 30 is provided on the boom assembly 20. The lighting device 30 is adapted to move synchronously with the boom assembly 20. It can be understood that the boom assembly 20 can further expand the movement range and the working height of the lighting lamp 300, so that the lighting range of the lighting lamp 300 can be further increased; it should be noted that the fire truck provided by the embodiment of the present utility model has the lighting device 30 according to any one of the foregoing embodiments, and therefore, also has the beneficial effects of any one of the foregoing lighting devices 30.

[0064] Continue to refer to Figures 6 to 9, in an alternative embodiment of the present utility model, the boom assembly 20 includes a first boom 21, a second boom 22, and a third boom 23. One end of the first boom 21 is connected to the vehicle body 10, and the other end is movably connected to the second boom 22. The end of the second boom 22 away from the first boom 21 is movably connected to the third boom 23. The lighting device 200 is provided on at least one of the first boom 21, the second boom 22, and the third boom 23. It can be understood that when the lighting device 30 is installed on the third boom, that is, at the end of the entire boom assembly 20, it can be directly used for lighting at the fire scene, which can ensure that firefighters can better judge the fire situation. When the lighting device 30 is installed on the first boom 21 and the second boom 22, it can be used for lighting at the rescue scene. By adaptively adjusting the installation position of the lighting device 30, it can meet more operation requirements. Specifically, it can be adaptively set according to the actual situation, which will not be elaborated herein.
