Description

Technical Field

[0001] The utility model relates to the technical field of square cabins, in particular to an integrated structure of a cabin bottom plate and a sub-frame. Background Art

[0002] The emergency power supply vehicle is a modified vehicle. The power supply vehicle is a container power station installed on a separately purchased vehicle chassis for easy transportation. Since the width of the vehicle chassis is narrow, placing the container power station directly on the vehicle chassis will cause instability. Therefore, it is generally adopted to add a subframe to carry the container power station.

[0003] The structure of the traditional subframe is as follows Figure 1 As shown, the structure of the auxiliary frame is simple, and the longitudinal beam 11 and the side beam 13 are welded to each other, and an oblique beam 12 is welded between the longitudinal beam 11 and the side beam 13. The auxiliary frame is only a frame body of a simple structure and only serves as a connection.

[0004] The specific installation process is to first lock the subframe 10 on the vehicle chassis with U-bolts, and then hoist the shelter power station 40 onto the subframe 10. Corner pieces 20 are provided at the four corners of the shelter power station, and the corner pieces 20 are fixedly connected to the subframe 10 through rotary locks 30. Figure 2 shown.

[0005] The above series of operations are used to install the modular power plant on the vehicle chassis, which is a cumbersome and costly process. Utility Model Content

[0006] In order to solve the problems in the prior art, the utility model provides an integrated structure of a cabin bottom plate and a sub-frame.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A cabin floor and subframe integrated structure, comprising a floor frame, a longitudinal beam fixedly connected to the bottom of the floor frame, and an oblique beam fixed between the longitudinal beam and the longitudinal edge of the floor frame; an upper skin and a lower skin are fixedly provided on the upper and lower sides of the floor frame, respectively, and a filling material is provided in the cavity area between the floor frames;

[0009] The longitudinal beams and the oblique beams form a subframe part, which is connected to the vehicle chassis; the upper skin, the lower skin, the filling material and the bottom plate frame form a cabin bottom plate part, which is connected to the bottomless cabin.

[0010] Furthermore, the bottom plate frame includes a frame frame and an intermediate frame fixed in the frame frame. The intermediate frame is divided into a plurality of regions, and polyurethane foam boards are filled between the regions.

[0011] Furthermore, the intermediate frame is composed of a longitudinal frame and a transverse frame that are cross-fixed.

[0012] Furthermore, the upper skin and the lower skin are welded in blocks at corresponding areas of the middle frame.

[0013] Furthermore, a circle of positioning frame is provided on the periphery of the frame frame, a circle of stepped structure is formed between the positioning frame and the frame frame, and the bottom of the bottomless cabin is fixedly placed on the stepped structure.

[0014] Furthermore, the positioning frame is made of profiles, and the bottomless cabin is connected to the profiles by tap rivets.

[0015] Furthermore, the bottom of the positioning frame is flush with the bottom of the frame frame, and the top of the positioning frame is lower than the top of the frame frame, thereby forming a circle of stepped structure.

[0016] Furthermore, a plurality of connecting plates are distributed on the longitudinal beam along the longitudinal direction, and each connecting plate is provided with a connecting hole for fitting with a U-shaped bolt.

[0017] Furthermore, a tool box bracket is fixedly provided below the bottom plate frame, and the tool box bracket is also fixedly connected to the longitudinal beam.

[0018] Beneficial effects of the utility model:

[0019] 1. The utility model combines the subframe with the bottom plate of the shelter to form an integrated structure, and at the same time changes the shelter into a pentahedral (bottomless) structure. Compared with the existing connection method, the integrated structure of the utility model reduces the number of installed parts and the total vehicle weight, which better meets the acceptance standards of emergency power supply vehicles.

[0020] 2. The utility model is more conducive to acceptance: Since the emergency power supply vehicle has strict external dimension standards during acceptance, the utility model reduces the thickness of one plate by combining the bottom plate and the auxiliary frame into one, thereby reducing the height of the entire vehicle.

[0021] 3. The previous shelter floor was made of hot-pressed skin, which could only be installed after forming. The toolbox, airbag and other parts installed under the vehicle chassis could only be installed in advance. After the shelter floor was installed, the toolbox position could not be seen from top to bottom or adjusted;

[0022] The integrated structure adopted by the utility model can be installed first, the relative position between the tool box and the integrated structure can be adjusted, and then the skin can be cold pressed and bonded;

[0023] 4. The utility model is more convenient for maintenance: before the structure is changed, when the unit needs to be repaired, the entire bottomless cabin needs to be hoisted down as a whole or the unit needs to be disassembled for maintenance. Now, it is only necessary to hoist the pentahedral cabin to expose the internal unit.

[0024] 5. The utility model also has a circle of positioning frame on the outer periphery of the frame frame, and a circle of stepped structure is formed between the positioning frame and the frame frame. The bottomless square cabin is connected to the positioning frame by tap rivets, eliminating the original twist lock connection method. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] like Figures 3 to 6 As shown, this embodiment provides an integrated structure of a cabin bottom plate and a sub-frame, including a bottom plate frame.

[0034] Specifically, the bottom frame includes a frame frame 1 and an intermediate frame 2 fixed in the frame frame. The intermediate frame 2 is composed of a longitudinal frame and a transverse frame fixedly arranged crosswise, so that the intermediate frame 2 is divided into many areas, and polyurethane foam boards 9 are filled between each area.

[0035] The upper and lower surfaces of the bottom plate frame are fixed with an upper skin 3 and a lower skin 4, respectively. When installing, the upper skin 3, the lower skin 4, the bottom plate frame, and the polyurethane foam board 9 are first coated with structural adhesive, and then riveted and fixed. The upper skin 3 and the lower skin 4 are welded in blocks to the corresponding areas of the middle frame 2.

[0036] A longitudinal beam 5 is fixedly connected to the bottom of the bottom plate frame, and an oblique beam 6 is fixed between the longitudinal beam 5 and the longitudinal edge of the frame frame 1 .

[0037] The longitudinal beam 4 and the diagonal beam 6 form a subframe part, which is connected to the vehicle chassis. The upper skin 3, the lower skin 4, the polyurethane foam board 9 and the bottom plate frame form a cabin bottom plate part, which is connected to the pentahedral (bottomless) square cabin.

[0038] In order to facilitate the connection between the bottom plate of the cabin and the pentahedral (bottomless) square cabin, a circle of positioning frame 7 is also provided on the periphery of the frame frame 1. The bottom of the positioning frame 7 is flush with the bottom of the frame frame 1, and the top of the positioning frame 7 is lower than the top of the frame frame 1, thereby forming a circle of stepped structure at the positioning frame 7 and the frame frame 1, and the bottom of the bottomless square cabin is fixedly placed on the stepped structure.

[0039] In this embodiment, the positioning frame 7 is made of profiles, and the bottomless cabin is connected to the profiles by tap rivets, eliminating the original twist lock connection method.

[0040] In order to facilitate the connection between the sub-frame part and the vehicle chassis, a plurality of connecting plates 51 are distributed along the longitudinal direction on the longitudinal beam 5, and each connecting plate 51 is provided with a connecting hole for U-bolt cooperation, so as to facilitate the locking of the sub-frame part to the vehicle chassis by U-bolt.

[0041] In order to facilitate the installation of the tool box, a tool box bracket 52 is fixedly provided below the bottom plate frame, and the tool box bracket 52 is also fixedly connected to the longitudinal beam 5.

[0042] The utility model combines the subframe with the bottom plate of the cabin to form an integrated structure, and at the same time changes the cabin into a pentahedron (bottomless) structure, and the unit is directly installed on the integrated structure. Compared with the existing connection method, the integrated structure of the utility model reduces the number of installed parts and the total vehicle weight, which better meets the acceptance standards of emergency power supply vehicles and achieves new breakthroughs in installation technology and weight limit requirements.

[0043] The utility model is more conducive to acceptance: since the emergency power supply vehicle has strict external dimension standards during acceptance, the utility model reduces the thickness of one plate after the bottom plate and the auxiliary frame are combined into one, thereby reducing the height of the whole vehicle.

[0044] The utility model is more convenient for maintenance: before the structure is changed, when the unit needs to be repaired, the entire bottomless square cabin needs to be hoisted down as a whole or the unit needs to be disassembled for maintenance. Now, it is only necessary to hoist the pentahedral square cabin to expose the internal unit.
