[0002] A fire truck refers to a vehicle designed and manufactured according to needs, suitable for firefighters to ride, equipped with various fire-fighting equipment or fire extinguishing agents, and used by fire brigades for fire fighting, auxiliary fire fighting or fire rescue.
[0003] Usually, equipment boxes for placing firefighting equipment are set on both sides of the fire truck, and rolling doors for closing the equipment boxes are set at the corresponding positions of the equipment boxes. When the fire truck is performing its mission, if the fire truck is hit, causing the rolling door to deform, it is easy for the rolling door to be unable to open. Therefore, it is necessary to develop a skirt structure that can effectively protect the rolling door of the fire truck. Utility Model Content
[0004] In order to protect the rolling shutter door of a fire truck and reduce its deformation caused by collision, the present application provides a rear compartment skirt panel structure component of a fire truck.
[0005] The present application provides a fire truck rear compartment skirt plate structural assembly adopts the following technical solution:
[0006] A fire truck rear compartment skirt panel structural assembly includes a mounting frame fixedly connected to a vehicle box, the mounting frame is slidably provided with a slide seat, a skirt panel for protecting the vehicle box is hinged on the slide seat, a supporting frame for supporting the skirt panel is provided on the mounting frame, and a fixing unit for fixing the skirt panel is provided on the vehicle box.
[0007] By adopting the above technical solution, when the operator needs to open the rolling door, the skirt board is in the storage state, the slide is located in the mounting frame, and the skirt board is overlapped on the supporting frame. When the operator closes the rolling door, the operator pulls the slide outward and then turns the skirt board up, so that the skirt board is shielded outside the rolling door of the side wall of the vehicle, which plays a protective effect and reduces the situation where the rolling door cannot be opened due to collision of the vehicle.
[0008] Optionally, the fixing unit includes a plurality of support seats fixedly connected to the vehicle box, an elastic plate is hinged on one side of the support seat, and a clamping seat for limiting the skirt plate is fixedly connected to the elastic plate.
[0009] By adopting the above technical solution, when the operator flips up the skirt board, the skirt board moves toward the support seat, and then the operator operates to flip the guide rod to overcome the elastic force of the elastic plate, so that the edge of the skirt board can overlap the support seat. The operator then loosens the elastic plate, and the elastic plate resets under the action of its own elastic force, so that the skirt board is located between the clamping seat and the support seat, thereby achieving a limiting effect on the skirt board.
[0010] Optionally, a slope is provided on a side of the holder facing away from the support seat, and an end of the slope away from the support plate is inclined toward the support seat.
[0011] By adopting the above technical solution, an inclined surface is set to guide the skirt plate, so that when the skirt plate moves toward the support seat, the skirt plate pushes the inclined surface to drive the guide rod to overcome the elastic force of the elastic plate and tilt away from the support seat. When the skirt plate passes over the clamping seat, the elastic plate is reset under the action of its own elastic force, so that the skirt plate is clamped between the clamping seat and the support seat.
[0012] Optionally, a rotating shaft is fixedly connected to the skirt plate, and a sleeve for abutting against the holder is sleeved on the rotating shaft, and a supporting plate for moving the holder is provided on the sleeve.
[0013] By adopting the above technical solution, the sleeve is clamped between the holder and the support seat to achieve the limiting effect on the skirt board. The operator flips the support plate and pushes the holder through the support plate to release the limiting effect of the sleeve on the holder, making it convenient for the operator to flip the skirt board downward and store it at the bottom of the car body.
[0014] Optionally, a second spring for pushing the sleeve to move is sleeved on one end of the rotating shaft, a plurality of slots are opened on the end of the sleeve away from the second spring, and the plurality of slots are spaced apart around the axis of the sleeve, and a ring plate is fixedly connected to the end of the rotating shaft away from the second spring, and an insert block for inserting into the slot is fixedly connected to the ring plate.
[0015] By adopting the above technical solution, the second spring pushes the sleeve so that the plug block is inserted into one of the slots on the sleeve, thereby limiting the rotation of the sleeve, making it convenient for the operator to control the position of the sleeve. When the operator needs to flip the support plate, the operator moves the sleeve toward the second spring so that the plug block is disengaged from the slot, so that the operator can flip the support plate. After the support plate is flipped, the operator releases the support plate, and the sleeve moves toward the ring plate under the elastic force of the second spring, so that the plug block is re-inserted into the slot at the corresponding position.
[0016] Optionally, a base is fixedly connected to the vehicle body, a receiving groove is provided on the base, an end cover is provided at the opening position of the receiving groove, a guide column is slidably provided on the end cover, one end of the guide column located in the receiving groove is fixedly connected to a convex ring, the support seat is provided with a first spring in the receiving groove for pushing the convex ring to abut against the end cover, and one end of the guide column located outside the receiving groove is fixedly connected to a cross bar that is pressed against the skirt panel.
[0017] By adopting the above technical solution, when unfolding the skirt board, the operator needs to pull the skirt board outward so that the slide seat moves outward to the extreme position, and then flip the skirt board up. During the process of flipping up the skirt board, it first abuts against the cross bar. When the skirt board continues to flip up, the cross bar is pushed, so that the guide column overcomes the elastic force of the first spring and moves toward the machine body until the skirt board is engaged between the card seat and the support seat. The cross bar is pushed by the first spring to press against the skirt board, which helps to reduce the shaking of the skirt board during vehicle driving.
[0018] Optionally, a roller is rotatably connected to the cross bar, a ridge plate for abutting against the roller is fixedly connected to the skirt plate, and a groove for cooperating with the ridge plate is provided on the circumferential surface of the roller.
[0019] By adopting the above technical solution, the roller cooperates with the edge plate to reduce the wear caused by relative movement when the cross bar and the skirt plate are pressed against each other.
[0020] Optionally, a plurality of guard plates are detachably and fixedly connected to a side of the skirt panel facing away from the vehicle box.
[0021] By adopting the above technical solution, the guard plate can be detachably installed on the skirt plate, which makes it convenient to install and remove the guard plate and reduces the wear of the skirt plate.
[0022] To summarize, the present application includes at least one of the following beneficial technical effects: the operator pulls the slide outward and then flips up the skirt so that the skirt is shielded outside the rolling door of the side wall of the vehicle body, thereby playing a protective role and reducing the risk of collision to the vehicle body, which may cause the rolling door to be unable to open.

[0030] The following is combined with Figure 1-6 This application is described in further detail.
[0031] The present application embodiment discloses a fire truck rear compartment skirt plate structural assembly. Figure 1 and Figure 2 The rear compartment skirt structural assembly of the fire truck includes a mounting frame 11 fixedly connected to the bottom of the vehicle box 1, and two guide rods 12 are arranged on the mounting frame 11 in parallel with each other. Both ends of the guide rods 12 are fixedly connected to the bottom of the mounting frame 11 through connecting plates. Sliding sleeves 13 are slidably provided on the two guide rods 12, and the two sliding sleeves 13 are fixedly connected by a sliding seat 14. A rectangular skirt 15 is hingedly connected to the side of the sliding seat 14 facing outside the vehicle box 1. The hinge axis between the skirt 15 and the sliding seat 14 is parallel to the length direction of the skirt 15. A guard plate 17 for protecting the skirt 15 is detachably fixedly connected to the side of the skirt 15 away from the vehicle box 1 by screws. Supporting plates 16 for supporting the skirt 15 are fixedly connected to the positions corresponding to the two guide rods 12 at the bottom of the mounting frame 11. When the sliding seat 14 is located at the end of the guide rod 12 away from the outside of the vehicle box 1, the skirt 15 is supported on the supporting plate 16. When the slide 14 moves to the end of the guide rod 12 close to the outside of the vehicle box 1, the skirt plate 15 can be flipped upward to a vertical state and cover the rolling door of the vehicle box 1 to achieve a protective effect.
[0032] like Figure 3 and Figure 4The carriage 1 is provided with a fixing unit 2 for fixing the skirt board 15. The fixing unit 2 includes two support seats 21 fixedly connected to the carriage 1. The two support seats 21 are arranged at intervals along the length direction of the skirt board 15. The upper surface of the support seat 21 is fixedly connected to an elastic plate 22, and the lower surface of the elastic plate 22 away from the support seat 21 is fixedly connected to a clamping seat 23. A clamping groove 33 for clamping the skirt board 15 is formed between the clamping seat 23 and the support seat 21. The side of the clamping seat 23 away from the support seat 21 is provided with an inclined surface 24, and the side of the inclined surface 24 close to the support seat 21 is inclined downward. The side of the skirt board 15 away from the slide seat 14 is fixedly connected to a rotating shaft 3, and a sleeve 31 for clamping into the clamping groove 33 is rotatably connected to the rotating shaft 3. A support plate 32 for moving the holder 23 is fixedly connected to the sleeve 31 . When the sleeve 31 is inserted into the slot 33 , the operator can flip the support plate 32 and push the holder 23 through the support plate 32 , so that the holder 23 releases the limiting effect on the sleeve 31 .
[0033] A second spring 34 for pushing the sleeve 31 is sleeved on the rotating shaft 3. A ring plate 35 is coaxially fixedly connected to the end of the sleeve 31 away from the second spring 34. An insert block 36 is fixedly connected to the end of the ring plate 35 facing the sleeve 31. A plurality of slots 37 for inserting the insert blocks 36 are opened on the sleeve 31, and the plurality of slots 37 are evenly distributed around the circumference of the sleeve 31. When the plug block 36 is inserted into one of the slots 37, the sleeve 31 is restricted from rotating. When the operator needs to flip the support plate 32, the operator needs to move the support plate 32 toward the second spring 34, so that the plug block 36 disengages from the slot 37, and the plug block 36 releases the limiting effect on the sleeve 31, and then pushes the support plate 32 to flip, thereby driving the sleeve 31 to rotate. When the operator releases the support plate 32, the sleeve 31 moves toward the ring plate 35 under the elastic force of the second spring 34, so that the plug block 36 on the ring plate 35 is inserted into the slot 37 at the corresponding position, once again restricting the rotation of the sleeve 31.
[0034] like Figure 5 and Figure 6 Two embedding grooves are provided at the positions of the skirt boards 15 near the bottom of the carriage 1. The two embedding grooves are arranged at intervals along the length direction of the skirt boards 15, and the base 4 is fixedly connected in the embedding grooves. The side of the base 4 facing the skirt boards 15 is provided with a receiving groove 41. The base 4 is fixedly connected with an end cover 42 at the opening position of the receiving groove 41. Two guide pillars 43 are slidably provided on the end cover 42, and the axial directions of the two guide pillars 43 are perpendicular to the surface of the base 4 on the carriage 1. A convex ring 44 is fixedly connected to one end of the guide pillar 43 extending into the base 4, and a first spring 45 for pushing the convex ring 44 to move toward the end cover 42 is provided on the base 4. A cross bar 46 is fixedly connected to the end cover 42, and the ends of the two guide pillars 43 extending out of the base 4 are fixedly connected to the cross bar 46.
[0035] like Figure 2 and Figure 6 A roller 47 is rotatably connected to the cross bar 46 , and an annular groove 48 is formed on the roller 47 along its circumferential direction. The skirt board 15 is fixedly connected to a ridge plate 49 at a position corresponding to the roller 47 , and the length direction of the ridge plate 49 is parallel to the width direction of the skirt board 15 .
[0036] During the upward flipping process of the skirt board 15, the skirt board 15 first abuts against the roller 47 and pushes the roller 47 to move toward the vehicle body 1. During this process, the first spring 45 is compressed and causes the roller 47 to abut against the edge plate 49. When the sleeve 31 is inserted into the slot 33, the skirt board 15 is pushed by the first spring 45 so that the sleeve 31 abuts against the seat 23, thereby reducing the shaking of the skirt board 15 during the driving of the fire truck.
[0037] The working principle of the embodiment of the present application is as follows: when the skirt board 15 is flipped up, the edge plate 49 on the skirt board 15 is pressed against the roller 47, and the sleeve 31 at the end of the skirt board 15 away from the slide seat 14 is clamped in the clamping groove 33. At this time, the skirt board 15 blocks the outer side of the rolling door, which has a protective effect on the rolling door and reduces the situation where the rolling door is damaged and difficult to open when the car body 1 collides.
[0038] When the operator needs to open the rolling door, the operator moves the support plate 32 toward the second spring 34. During this process, the second spring 34 is compressed, and the plug 36 is disengaged from the corresponding slot 37. Then the operator flips the support plate 32 so that the support plate 32 pushes the holder 23 to release the limiting effect on the sleeve 31. The operator then moves the support plate 32 toward the ring plate 35 so that the plug 36 is inserted into the slot 37 at the corresponding position. At this time, the holder 23 remains disengaged from the sleeve 31. The operator flips each support plate 32 in this way to release the limiting effect of the skirt plate 15 on the vehicle box 1. Finally, the operator flips the skirt plate 15 down and pushes the skirt plate 15 into the bottom of the vehicle box 1 so that the skirt plate 15 is supported on the two supporting plates 16, completing the storage of the skirt plate 15.
[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
