DETAILED DESCRIPTION

[0032] In view of this, the core of the present invention is to design an integrated bracket for an electric air compressor assembly to shorten the assembly time of a whole vehicle on the assembly line and improve the assembly efficiency of the whole vehicle on the assembly line.

[0033] Another core of the present invention is to design a pure electric mining dump truck with the above-mentioned integrated bracket.

[0034] In order to enable those skilled in the art to better understand the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0035] Please refer to the attached Figure 1 The utility model discloses an integrated bracket for an electric air compressor assembly, which includes a mounting base 1 and an air reservoir mounting bracket 2. The mounting base 1 is connected to one end of a lifting beam 5. The lifting beam 5 is located between the vehicle body and the cab, and the lifting beam 5 extends along a first direction. The first direction can be an attached Figure 1The x direction is the left and right direction of the pure electric mining dump truck. The lifting beam 5 is used to support the car body. One end of the lifting beam 5 has a certain space, and the utility model is provided with an integrated bracket in the space.

[0036] The air cylinder mounting bracket 2 includes a plurality of legs 201 and an air cylinder mounting bracket 202 connected to the legs 201. The legs 201 are arranged vertically, with their bottoms connected to the mounting base 1. The air cylinder mounting bracket 202 is arranged horizontally and positioned above the mounting base 1. The air cylinder 3 is mounted on the air cylinder mounting bracket 202. The space between the air cylinder mounting bracket 202 and the mounting base 1 is used to accommodate the electric air compressor 4.

[0037] In this utility model, the electric air compressor assembly is mounted offline on an integrated bracket to form a complete assembly unit. During assembly of the entire vehicle on the assembly line, only the assembly unit needs to be installed on the lifting beam 5, thereby shortening assembly time and improving assembly efficiency. Furthermore, this utility model rationally utilizes the space at the end of the lifting beam 5, enabling installation of the assembly unit without altering the existing vehicle structure.

[0038] The gas cylinder mounting bracket 202 for mounting the gas cylinder 3 includes two support beams 203, arranged opposite each other in a first direction. A gas cylinder support 206 is mounted on each of the support beams 203. The two gas cylinder supports 206 form a gas cylinder support assembly. The gas cylinder support assembly supports a gas cylinder 3, which is secured to the two gas cylinder supports 206 via two ties. This ties not only ensures the stability of the gas cylinder 3 but also facilitates its removal and replacement.

[0039] Please refer to the attached Figure 2 、 3 The gas cylinder support 206 specifically includes a connecting plate 2061, a support plate 2060, and a baffle 2062. A connecting plate 2061 is connected to the outer surface of one of the two support beams 203 that is away from the lifting beam 5. One side of the support plate 2060 is connected to the upper part of the connecting plate 2061, and the other side of the support plate 2060 extends to the outside of the gas cylinder mounting bracket 202. In other words, the other side of the support plate 2060 extends in a direction away from the lifting beam 5. The supporting surface of the support plate 2060 is a concave arc surface that matches the outer surface of the gas cylinder 3 to ensure that the gas cylinder 3 is stably placed on the supporting surface. Since the support plate 2060 is located on the outside of the gas cylinder mounting bracket 202, it will not be interfered with by the gas cylinder mounting bracket 202 when tightening the gas cylinder 3, ensuring the smooth tightening operation.

[0040] Baffle 2062 is connected to the back side of support plate 2060, that is, to the side of support plate 2060 facing away from the supporting surface. Baffle 2062 and connecting plate 2061 are arranged opposite each other in the first direction. The area where the band contacts the back side of support plate 2060 is located between connecting plate 2061 and baffle 2062. Baffle 2062 and connecting plate 2061 block the band, preventing it from moving freely in the first direction, thereby improving the stability of air reservoir 3.

[0041] Please refer to the attached Figure 4 -Attached Figure 6 The gas cylinder mounting bracket 202 is provided in two groups, one above the other, along the support leg 201. Each group of gas cylinder mounting brackets 202 is provided with two groups of gas cylinder support groups, and the two groups of gas cylinder support groups are arranged along the second direction, which is perpendicular to the first direction in the horizontal plane. The second direction can be attached Figure 1 The y direction is the front-rear direction of the pure electric mining dump truck. Two gas cylinders 3 are arranged side by side along the second direction on each group of gas cylinder mounting brackets 202, so a total of four gas cylinders 3 are arranged, thereby increasing the supply of gas source.

[0042] An air compressor filter mounting plate 204 is provided on a leg 201 that is distal from the lifting beam 5 in the first direction. The air compressor filter mounting plate 204 is positioned adjacent to the air accumulator mounting bracket 202. One side of the air compressor filter mounting plate 204 is connected to the leg 201, while the other side extends outward from the air accumulator mounting bracket 202. This allows the air compressor filter 6 to be installed outside the air accumulator mounting bracket 2, thereby avoiding interference from the air accumulator mounting bracket 2 and facilitating smoother installation of the air compressor filter 6.

[0043] The air compressor air filter mounting plate 204 is provided with bolt holes, and the air compressor air filter 6 is mounted on the air compressor air filter mounting plate 204 using bolts that match the bolt holes. The air outlet of the air compressor air filter 6 is connected to the first air inlet pipe 8, and the air compressor air filter mounting plate 204 is provided with a through hole for the first air inlet pipe 8 to pass through, forming a clearance for the first air inlet pipe 8.

[0044] As can be seen from the above description, the air reservoir mounting bracket 202 has two support beams 203 arranged opposite each other in the first direction. In this embodiment, an air muffler mounting plate 205 is connected to the outer side of the support beam 203 farther from the lifting beam 5 in the first direction. The support beam 203 farther from the lifting beam 5 in the first direction is the one of the two support beams 203 that is closer to the air compressor air filter mounting plate 204. The air muffler mounting plate 205 is used to mount the air muffler 7. The inlet end of the first air intake pipe 8 is connected to the outlet end of the air compressor air filter 6, which in turn is connected to the inlet end of the air muffler 7. Because the air muffler 7 is closer to the air compressor air filter 6, the first air intake pipe 8 can be shorter. The outlet end of the air muffler 7 is connected to the inlet end of the second air intake pipe 9, which in turn is connected to the inlet end of the electric air compressor 4. The first air inlet pipe 8 and the second air inlet pipe 9 are preferably hoses, which have a certain flexibility and are conducive to changing direction.

[0045] A first pipe connector mounting bracket 207 is provided on a leg 201 located in the first direction and adjacent to the lifting beam 5. The first pipe connector mounting bracket 207 is provided with a first mounting hole, into which the first pipe connector is mounted. One end of the first outlet pipe 11 is connected to the outlet of the electric air compressor 4, and the other end is threadedly engaged with the inlet of the first pipe connector. Specifically, the first pipe connector has its own external threads and is secured to the first pipe connector mounting bracket 207 via a first locking nut. A nut is movably connected to the outlet end of the first outlet pipe 11, which is threadedly engaged with the first pipe connector via this nut.

[0046] A second pipe connector mounting bracket 102 is connected to the side of the mounting base 1 near the lifting beam 5. This bracket 102 extends horizontally beyond the mounting base 1. A second mounting hole is provided on the bracket 102, into which a second pipe connector is mounted. The outlet of the second pipe connector faces the wire hole in the lifting beam 5. The inlet of the second outlet pipe 10 is threadedly connected to the outlet of the first pipe connector, and the outlet of the second outlet pipe 10 is threadedly connected to the inlet of the second pipe connector.

[0047] Specifically, a nut is movably connected to the inlet end of the second outlet pipe 10, which is screwed onto the first pipe joint via the nut. The second pipe joint has its own external threads, which are locked onto the second pipe joint mounting bracket 102 via a second locking nut. A nut is movably connected to the outlet end of the second outlet pipe 10, which is screwed onto the inlet end of the second pipe joint via the nut.

[0048] External equipment associated with the electric air compressor 4 is located beneath the lifting beam 5. The outlet of the second pipe connector is connected to the external equipment via a connecting pipe. Because the outlet of the second pipe connector faces the cable hole on the lifting beam 5, the connecting pipe can be connected to the external equipment below through the cable hole, simplifying wiring.

[0049] The first air outlet pipe 11 is preferably a high-temperature hose, and the second air outlet pipe 10 is preferably a steel pipe. There is a large distance between the air outlet end of the electric air compressor 4 and the second pipe joint in both the horizontal and vertical directions. If a hose is directly set between the air outlet end of the electric air compressor 4 and the second pipe joint, the length of the hose is long and it is easy to deform, thereby affecting the smooth discharge of the gas source. Therefore, this specific implementation adopts the form of a high-temperature hose plus a steel pipe. The high-temperature hose leads the air outlet end of the electric air compressor 4 to the first pipe joint, and then a steel pipe is set between the first pipe joint and the second pipe joint. The length of the high-temperature hose is short and will not affect the discharge of the gas source. The steel pipe consists of a horizontal pipe and a vertical pipe, and the structure is relatively simple, which is convenient for processing and manufacturing.

[0050] The mounting base 1 specifically includes a mounting base plate 100 and a side plate 101. The mounting base plate 100 is used to mount the electric air compressor 4. In the second direction perpendicular to the first direction in the horizontal plane, that is, the side plate 101 is provided. Figure 1 In the y direction, side plates 101 are respectively provided on both sides of the mounting base 100, and bolt holes connected to the side portions of the lifting beam 5 are provided on the side plates 101. Preferably, the side plates 101 can be bent plates that are bent downwardly from the mounting base 100.

[0051] The mounting base 100 extends in the first direction beyond the lifting beam 5. A downwardly extending power switch mounting bracket 103 is provided on the side of the mounting base 100 facing away from the lifting beam 5. This bracket is used to mount the power switch 12. The power switch 12 is located at the end of the lifting beam 5. When the driver parks the vehicle and exits the cab, the power switch 12 is easily accessible, making it easier to operate.

[0052] The present utility model also discloses a pure electric mining dump truck, including an integrated bracket for an electric air compressor assembly. In particular, the integrated bracket is any one of the above-mentioned integrated brackets, and the above-mentioned integrated bracket has the above-mentioned effect. The pure electric mining dump truck with the above-mentioned integrated bracket also has the above-mentioned effect, so it will not be repeated in this article.

[0053] In the description of the present invention, it should be noted that the terms "upper", "lower", "bottom", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present application.

[0054] Furthermore, the use of terms such as "horizontal," "vertical," and "perpendicular" does not necessarily mean that the component must be absolutely horizontal or vertical, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0055] In addition, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0056] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
