Description

Technical Field

[0001] The utility model belongs to the technical field of cargo compartments, and particularly relates to a cargo compartment structure capable of reducing abnormal noise. Background Art

[0002] Van trucks feature either a separate enclosed cabin or an integrated, enclosed cabin integrated with the driver's cab. They are primarily used for commercial transport of goods. They offer advantages such as maneuverability, ease of operation, high efficiency, high transport capacity, efficient space utilization, safety, and reliability. They can be used on various intercity highways as well as within urban areas.

[0003] The compartment of a van is used to place goods, and is usually composed of a frame and plates. The plates are fixed on the frame. Due to its split structure, slight looseness is prone to occur in the connection, and the connection between the frame and the plates is not stable enough. After a period of use, the vehicle will vibrate and make abnormal noises during driving; especially the frame is generally only connected to the edge of the plate, resulting in insufficient support force of the frame for the plate, and then insufficient strength of the connection between the plate and the frame, which will cause local looseness and vibration and noise during driving. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a cargo compartment structure that reduces abnormal noise, so as to solve the technical problem in the prior art that the cargo compartment will generate abnormal noise during vehicle driving after being used for a period of time.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: a cargo compartment structure for reducing abnormal noise, comprising:

[0006] A front plate, wherein the front plate is a corrugated steel plate;

[0007] A top plate, the top plate being a corrugated steel plate, and a first support rod being provided at intervals on the bottom surface of the top plate;

[0008] Two side panels, the outer layers of the two side panels are flat steel plates, and the inner layers of the side panels are reinforced structures;

[0009] The rear panel is a double-door panel, the outer layer of the rear panel is a flat steel plate, and the inner layer of the rear panel is the reinforcement structure.

[0010] The utility model mainly reinforces the side panels and the rear panel by strengthening the structure, so as to improve the rigidity of the side panels and the rear panel and avoid abnormal noise generated in the vehicle compartment during driving.

[0011] Furthermore: the reinforcement structure includes:

[0012] A plurality of vertical first support rods are arranged at intervals;

[0013] A plurality of horizontal second support rods are arranged on the first support rod at intervals, and the second support rods are provided with clearance grooves at positions corresponding to the first support rods, and the second support rods are fixedly connected at overlapping positions with the first support rods.

[0014] The beneficial effect of adopting this step is that the reinforcement structure is a grid structure composed of the first support rod and the second support rod, which can further increase the number of connection points with the steel plate and reduce the distance between the connection points to provide good fixed support for the steel plate.

[0015] Furthermore: both sides of the first support rod and the second support rod are provided with outward flanges.

[0016] The beneficial effect of adopting this step is that flanging can increase the connection area between the support rod and the steel plate and improve the connection strength.

[0017] Furthermore: a flexible cushion layer is provided between the flange and the steel plate.

[0018] The beneficial effect of adopting this step is: the flexible cushion layer can fill the gap between the steel plate and the support rod, avoiding abnormal noise caused by vibration.

[0019] Furthermore: a plurality of through holes are formed on the second support rod.

[0020] The beneficial effect of adopting this step is: the through hole is used to reduce the weight of the second support rod.

[0021] Furthermore: a mounting plate is provided at the position of the first support rod of the top plate corresponding to the upper edge of the side plate, the mounting plate is L-shaped, the vertical plate of the mounting plate is fixedly connected to the side plate, and the horizontal plate of the mounting plate is fixedly connected to the first support rod.

[0022] The beneficial effect of adopting this step is that the welding strength between the first support rod of the top plate and the side plate is improved by the installation plate.

[0023] Furthermore: the thickness of the steel plate ranges from 0.6 to 1 mm; the tensile strength of the steel plate is ≥550 MPa.

[0024] The beneficial effect of adopting this step is: using a high-strength thin plate material as the material of the steel plate can not only ensure the overall structural strength of the carriage, but also facilitate production and processing.

[0025] The beneficial effects of the utility model are:

[0026] This application supports the side panels and rear panels at multiple positions through the reinforced structure, and strengthens the structure through the first support rod and the top panel, which can make the connection between the steel plate and the reinforced structure more stable, thereby making the overall structure of the car more stable and greatly reducing vibration and abnormal noise. In addition, a flexible pad is filled at the connection position between the steel plate and the reinforced structure, which can further reduce vibration and abnormal noise.

[0058] The through hole is used to reduce the weight of the second support rod 6 .
