Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1, fig. 2 and fig. 9, the power generation apparatus of the present invention mainly comprises an electric energy generation device and a casing, wherein the electric energy generation device is accommodated in the casing, and in this embodiment, the casing is a closed casing formed by splicing and combining a first casing 1, a second casing 2 and a casing cover 4. The present embodiment is provided with a handle 5 for lifting the power generating equipment at the upper part of the casing and feet 6 for supporting the power generating equipment at the bottom of the casing. For the generator set, the top of the shell is also provided with an oil tank opening 7 for filling fuel oil. In this embodiment: the electric energy generating device of the generator set mainly comprises an engine, a generator and an inverter; the electric energy generating device of the mobile power supply mainly comprises a battery, an inverter and a controller; the electric energy generating device of the solar photovoltaic power station mainly comprises an inverter and an electric control system, and certainly, the energy storage type solar power station also comprises a storage battery; the electric energy generator of electric welder is mainly transformer and electric control system.

As shown in fig. 2, 3 and 9, the housing in this embodiment has an approximately hexahedral shape, a handle 5 and an oil tank port 7 are provided at the top of the housing as needed, and feet 6 or roller devices are provided at the bottom of the housing. The first housing 1 in this embodiment is preferably manufactured by a blister processing technique, and the blister forming technique, i.e., a plastic plate thermal forming processing technique, is one of plastic secondary processing techniques. The plastic suction is different from injection molding, extrusion and other one-step processing technologies, and the plastic shell finished product is obtained by heating a plastic plate, carrying out plastic suction on the heated and softened plastic plate by using a vacuum suction force generated by a vacuum pump through a mould to form shell blanks in various shapes, and assisting with post-processing procedures such as trimming, hole opening and the like. The plastic suction processing has the advantages of low mold cost, high production efficiency and environmental protection. Because the second housing 2 and the housing cover 4 of the present invention have complicated structures, they are preferably manufactured by injection molding, but may be manufactured by die casting or extrusion as required.

As shown in fig. 9 to 14, since the plastic housing is manufactured with low dimensional accuracy and is easy to deform, gaps may exist between the mating surfaces of the second housing 2 and the housing cover 4 and the first housing 1, and in order to improve the sealing performance of the mating, in this embodiment, the sealing member 3 is disposed on the mating surfaces between the second housing 2 and the housing cover 4 and the first housing 1. Sealing member 3 is made by soft materials such as rubber or sponge, and for rectangular shape, can paste at

second casing

2 and 4 borders of cap through the non-setting adhesive, second casing 2 and cap 4 are assembled the back on first casing 1, and softer sealing member 3 is by extrusion deformation, has filled the gap between the casing fitting surface for casing leakproofness improves greatly.

As shown in fig. 1, 2 and 9, the housing in this embodiment is formed by jointly sealing and combining the first housing 1, the second housing 2 and the housing cover 4, and the electric energy generating device is accommodated and sealed in the housing. The shell is provided with functional units such as an electrical panel 8, the electrical panel 8 of the embodiment is arranged on the second shell 2, the electrical panel 8 comprises various output sockets, terminals, indicator lamps, a control switch and the like, the output sockets are connected with an electric energy generating device, and the generating equipment outputs electric energy through the electrical panel 8. For the mobile power supply, besides the electrical panel 8, a charging input panel is further disposed on the housing, and the commercial power, the solar energy, the generator and the like charge the energy storage battery in the mobile power supply through a charging port on the charging input panel, and of course, the charging port may also be disposed on the electrical panel 8 as needed. Because the electric energy generating device generates heat during operation, an air inlet 206 for cooling the electric energy generating device is further disposed on the housing of this embodiment, the air inlet 206 of this embodiment is disposed on the second housing 2, and an air outlet 405 for dissipating heat is disposed on the housing cover 4. In the present embodiment, a cooling fan is disposed in the housing, and under the driving of the cooling fan, the external air enters the housing from the air inlet 206 to cool the electric energy generating device, and then exits the housing from the heat dissipating air outlet 405.

As shown in fig. 2 to 14, the first casing 1 in the present embodiment is provided with an opening 103, and the second casing 2 is used for closing the opening 103. The first sealing surface 101 is provided along the periphery of the edge of the opening 103, and as shown in fig. 10 and 14, the first sealing surface 101 of the first housing 1 of the present embodiment is lower than the other surfaces of the periphery of the opening 103, and such a design structure contributes to further improving the sealing performance. As shown in fig. 3, 4 and 7, a rim sealing surface 202 is provided along the inner periphery of the rim of the second housing 2, and the rim sealing surface 202 is lower than the housing rim 201 of the second housing 2 and forms an equidistant structure with the housing rim 201. As shown in fig. 10 and 14, the present invention is characterized in that a sealing member 3 is disposed between the first sealing surface 101 and the edge sealing surface 202, and the sealing member 3 is made of a soft material such as rubber or sponge, and has a good sealing elasticity and a low cost. The sealing element 3 in this embodiment is in a long strip shape, the cross section of the sealing element is generally rectangular, or the sealing element is in an irregular shape with one side being a straight line, the straight line side forms a plane side of the sealing element 3, the plane side is provided with the self-adhesive, and the self-adhesive can be adhered to the edge sealing surface 202 and the rib sealing surface 204 on the second shell 2 in an adhering mode, so that the adhesion can be ensured to be tightly adhered to each other, the operation is simple, and the assembly production cost is reduced. After the second housing 2 is assembled to the first housing 1, the sealing member 3 is compressed, and the other side opposite to the flat side is tightly fitted to the first sealing surface 101 of the first housing 1 by compression, thereby achieving the case sealing.

As shown in fig. 10 and 14, in the embodiment, a screw column 205 is provided on the second housing 2, and a screw penetrates through the screw column 205 to couple and assemble the second housing 2 to the first housing 1, and when the second housing 2 is assembled in place, the housing rim 201 on the second housing 2 abuts against the first sealing surface 101 on the first housing 1, so that a cavity with a specific height h is formed between the first sealing surface 101 and the rim sealing surface 202, and the cavity structure of the sealing surface forms a space which just can accommodate the compressed sealing member 3. The step height h, as shown in fig. 7, is determined by the height difference between the housing rim 201 and the rim sealing surface 202, which is the height of the seal 3 after compression, and can be precisely controlled. Since the cross-section of the seal 3 in its length direction is the same everywhere, in order to ensure that the seal 3 is compressed the same everywhere, it is clear that the height difference between the housing rim 201 and the rim sealing surface 202 should also be the same everywhere, i.e.: the housing rim 201 and the rim sealing surface 202 should be equidistant to ensure that the height difference is the same from place to place and thus that the compression of the seal 3 is the same from place to place. As mentioned above, the compression amount of the sealing element 3 can be accurately controlled by reasonably designing the step height h on the edge of the second shell 2, so that the sufficient sealing effect is ensured, meanwhile, the sealing element 3 can be effectively prevented from being crushed, and the sealing service life is greatly prolonged.

As shown in fig. 14, since the width of the rim sealing surface 202 is small compared to the width of the sealing member 3, in order to ensure the adhesive strength between the sealing member 3 and the rim of the second housing 2, it is necessary to increase the contact area, and if the width of the rim sealing surface 202 is directly widened, the plastic member may be partially shrunk and deformed, which may affect the appearance quality. For this purpose, in the embodiment, a plurality of ribs 203 are disposed inside the edge of the second casing 2, the thickness of the ribs 203 is small, and no sink mark is generated, and the ribs 203 are disposed along the edge of the second casing 2 in a dispersed manner, as shown in fig. 5, and the ribs 203 are substantially uniformly distributed on the edge of the second casing 2 and are perpendicular to the edge of the second casing 2. As shown in fig. 4 and 7, the top of the rib 203 is formed with a rib sealing surface 204, and since the rim sealing surface 202 and the rib sealing surface 204 are both attached to the same side of the sealing member 3, in order to ensure the tight attachment, the rib sealing surface 204 should be a surface naturally extending from the rim sealing surface 202, and the rim sealing surface 202 and the rib sealing surface 204 should be the same surface, i.e., should be located in the same plane or curved surface.

As shown in fig. 2 and 9, the housing of this embodiment further includes a housing cover 4, an air outlet 405 for dissipating heat is disposed on the housing cover 4, and a sealing member 3 is also disposed on a mating surface between the housing cover 4 and the first housing 1. As shown in fig. 9, 11, 12, and 13, the edge of the case cover 4 is also provided with an edge sealing surface 402 that is equidistant from the edge 401 of the case cover, the inner side of the edge of the case cover 4 is also provided with a plurality of ribs 403, the tops of the ribs 403 form a rib sealing surface 404, and the edge sealing surface 402 and the rib sealing surface 404 are located on the same plane or curved surface. After the housing cover 4 and the first housing 1 are assembled in place, the housing cover edge 401 on the housing cover 4 can abut against the second sealing surface 102 on the first housing 1, so that a cavity structure with a specific height for accommodating the sealing element 3 is formed between the second sealing surface 102 and the edge sealing surface 402, the compression amount of the sealing element 3 can be accurately controlled by reasonably designing the height of the step on the edge of the housing cover 4, and the sealing effect between the housing cover 4 and the first housing 1 is ensured. As shown in fig. 11 and 13, the top of the rib 403 is higher than the rib sealing surface 404, where the step surface on the rib helps to position the sealing member 3, preventing the sealing member from deviating from the position when stuck, and improving the assembly productivity.

As shown in fig. 10, an LED lamp 9 is provided on the top of the appliance panel 8 on the second housing 2 for illuminating a user, and a plurality of lamps may be generally provided. Because the LED lamp 9 generates heat during operation, a dedicated cooling air duct is provided for the LED lamp 9 in this embodiment, under the driving of the fan in the housing, external cold air enters the space between the LED lamp 9 and the lamp cover from the top of the LED lamp 9 through the channel between the lamp cover and the lamp holder, the air after cooling the LED lamp 9 enters the housing from the channel in the lamp holder, and then is discharged out of the housing from the air outlet 405 under the driving of the fan.
