Description

Technical Field

[0001] The utility model relates to the technical field of power equipment, in particular to a chassis and a power unit. Background Art

[0002] At present, most power units on the market, such as generators, welding machines and DC chargers, usually need to be installed in a chassis to protect the internal units and provide a stable operating environment.

[0003] The chassis in the prior art generally includes a base, a plurality of side panels are fixed on the base, a top panel is connected to the top of the side panels, and the base, the side panels and the top panel are enclosed together to form a sealed box body. In order to facilitate the disassembly of the chassis, the side panels are generally connected to the base, the top panel and the adjacent side panels by bolts.

[0004] Although the existing chassis can be easily disassembled by bolts, there are still some problems in the process of use. First of all, since the chassis needs to be opened during repair, maintenance and regular inspection of the power unit, multiple bolts need to be removed before the chassis can be opened. This makes the unpacking work cumbersome and prolongs the working time of the staff. Especially when it is necessary to quickly eliminate the unit failure and resume the use of the unit as soon as possible, the unpacking work seriously affects the maintenance work. Secondly, in the process of multiple removal and installation of bolts, it is easy to cause the bolts to slip, thereby reducing the stability of the bolts and affecting the stability of the chassis. Utility Model Content

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] In a first aspect, a chassis is provided, comprising a base and a cover body arranged on the base, the cover body comprising a first cover body and a second cover body, the first cover body and the second cover body can be assembled to form the cover body, and the first cover body and the second cover body together with the base form a accommodating space when assembled, the first cover body is fixedly connected to the base, and the end of the second cover body away from the first cover body is hinged to the base through a hinge, and the free end of the second cover body can move in a direction away from the first cover body.

[0008] By adopting the above solution, when the chassis needs to be opened, the second cover body is lifted upward, and the second cover body rotates around the hinge point with the base, so that the second cover body is separated from the first cover body, thereby facilitating the inspection and maintenance of the unit installed in the chassis. There is no need to remove the bolts, making the operation of opening the chassis simple and quick, and reducing the time required to open the chassis for each maintenance of the unit.

[0009] The utility model is further configured such that a resilient member is connected to the base, the resilient member has a first end and a second end, the first end is hinged to the base, the second end is hinged to the second cover, and when the first end is close to the second end, the first end has a tendency to move away from the second end. When the second cover is lifted upward, the resilient member rebounds, making it easier to lift the second cover. When the second cover is opened to a suitable angle, the resilient member can prevent the second cover from tipping outward or inward.

[0010] The utility model is further configured that the resilient member is a pneumatic strut, which has good support and buffering performance and stable working performance, and can ensure the service life of the chassis.

[0011] The utility model is further configured such that a recessed portion is provided on the outer side of the first cover body, and the recessed portion is recessed toward the inner side of the first cover body. Since the unit installed in the chassis usually needs to be provided with a control panel outside the chassis to facilitate external control of the unit. The control panel can be installed in the recessed portion, so that the control panel does not protrude from the surface of the chassis, and the risk of the buttons of the control panel being damaged by scratches can be reduced.

[0012] The utility model is further configured such that a sound insulation area is provided inside the first cover body and / or the second cover body, and a sound insulation layer is provided in the sound insulation area. The sound insulation layer can effectively isolate the noise generated by the unit and reduce noise pollution.

[0013] The utility model is further configured that the free end of the second cover body is connected to the first cover body via a lock buckle, which can prevent the second cover body from being opened when not needed, thereby improving safety.

[0014] The utility model is further configured that the first cover body and / or the second cover body are provided with heat dissipation holes, through which the heat dissipation efficiency can be improved.

[0015] In a second aspect, a power unit is also provided, comprising a unit body, an exhaust duct and a chassis, wherein the unit body is installed in the accommodation space, the accommodation space is connected to an exhaust port connected to the outside, and the exhaust end of the exhaust duct is located in the exhaust port. Since the unit is installed in the chassis, the power unit body can be inspected and maintained by opening the second cover body, and the operation is simple and convenient.

In order to better protect the hinge 4, the hinge 4 can also be set on the inner side of the second enclosure 302.

[0032] By adopting the above solution, when in use, the unit that needs to be enclosed in the chassis is installed in the accommodating space. When the chassis needs to be opened, the second cover 3 is lifted upward, and the second cover 3 rotates around the hinge point with the base 1, so that the second cover 3 is separated from the first cover 2, thereby facilitating the inspection and maintenance of the unit installed in the chassis. There is no need to remove the bolts, making the operation of opening the chassis simple and quick, reducing the time required to open the chassis for each maintenance of the unit.

[0033] Please continue reading Figure 3 and Figure 4In order to facilitate the support of the second cover body 3 after it is opened, a resilient member 5 is connected to the base 1. The resilient member 5 has a first end and a second end. The first end is hinged to the base 1, and the second end is hinged to the second cover body 3. When the first end is close to the second end, the first end tends to move away from the second end. The resilient member 5 can specifically adopt a spring or other elastic connector or resilient assembly in the prior art to support the second cover body 3. In this embodiment, the resilient member 5 is preferably a pneumatic strut, which has good support and buffering performance and stable working performance, and can ensure the service life of the chassis.

[0034] Please continue reading Figure 1 In order to facilitate lifting the second cover 3 upward, a gripper 6 is fixedly installed at the left end of the top cover 301 to provide a fulcrum for the staff. In addition, since the unit installed in the chassis usually needs to be provided with a control panel outside the chassis, it is convenient to control the unit externally. In order to facilitate the installation of the control panel of the unit, a recessed portion 203 is provided on the front side of the first cover 2, and the recessed portion 203 is recessed toward the inner side of the first cover 2, and the recessed portion 203 is specifically located on the front side of the first enclosure 201.

The structure of the fixing frame 17 preferably adopts a rectangular frame to reduce the space occupied inside the chassis and provide operating space for maintenance of the unit.

[0039] In addition, since the unit body itself will also generate heat when working together, the temperature in the first chamber 9 increases. In order to reduce the temperature in the first chamber 9, further, a second air duct opening 12 is opened on the partition 8, and the second air duct opening 12 is located below the first air duct opening 11 and is arranged at intervals from the first air duct opening 11. An exhaust assembly (not shown in the figure) is provided at the second air duct opening 12, and the exhaust assembly is used to draw the air in the first chamber 9 into the second chamber 10 through the second air duct opening 12. The exhaust assembly can specifically adopt an exhaust fan in the prior art. In order to facilitate the air diversion in the second chamber 10, an air guide shell 13 is fixedly connected to the right side of the partition 8, and both the left and right ends of the air guide shell 13 are openings. The air guide shell 13 is a trumpet-shaped with an inner diameter gradually increasing from left to right, and the left end opening of the air guide shell 13 encloses the first air duct opening and the second air duct opening 12. When the exhaust assembly is working, the heat dissipation holes 14 on the rear side of the first enclosure 201, the heat dissipation holes 14 on the left side of the base 1, and the heat dissipation holes 14 opened at the bottom of the base 1 all serve as air inlets, and the heat dissipation holes 14 on the front and right side of the second enclosure 302 and the heat dissipation holes 14 on the right side of the base 1 all serve as air exhaust ports. Air is sucked in from the air inlet and discharged from the air exhaust port, forming airflow inside the chassis, thereby cooling the inside of the chassis.
