[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Please refer to Figures 1 to 3 , Figure 1 A cross-sectional view of a compressor end shell provided in an embodiment of the present application; Figure 2 A schematic diagram of the structure of the second end cover provided in an embodiment of the present application; Figure 3 This is a schematic diagram of the structure of the compressor provided in an embodiment of the present application.

[0037] For reference Figure 1 and Figure 3 The present application provides a compressor end shell, which can be installed at the end of the compressor casing and assembled with the compressor casing to form a shell of the compressor; the compressor end shell includes a first end cover 1 and a second end cover 2; one side of the aforementioned first end cover 1 is used to seal the motor chamber 011, and the other side of the first end cover 1 faces the second end cover 2, and can form a cavity 3 that can surround an electronic control device with the second end cover 2; part of the cover body of the aforementioned first end cover 1 is set as a thickened portion 11 and part of the cover body is set as a thinned portion, the thickness of the thickened portion 11 is greater than the thickness of the thinned portion, and is used to install the electronic control device.

[0038] In this embodiment, the first end cover 1 and the second end cover 2 can be assembled to form a cavity 3, and this cavity 3 is used to install the electronic control device of the compressor. The electronic control device can be independently set relative to the compression components such as the motor, piston pump or plunger pump in the compressor, which is conducive to simplifying the installation and maintenance of the electronic control device.

[0039] In this embodiment, one side of the first end cover 1 is used to seal the motor chamber 011 and the other end forms a cavity 3 with the second end cover 2. It can be seen that the first end cover 1 is arranged between the motor chamber 011 and the cavity 3, which allows the electronic control device to be close to the motor chamber 011 through the first end cover 1, thereby achieving cooling of the electronic control device by means of the low temperature environment of the motor chamber 011.

[0040] In this embodiment, part of the cover body of the first end cover 1 is set as a thickened portion 11 and part of the cover body is set as a thinned portion. The thickness of the thickened portion 11 is greater than the thickness of the thinned portion, which can meet the installation requirements and operating performance requirements of the electric control device. For example, in order to use a threaded fastener to lock and fix the electric control device, it is necessary to tap inside the first end cover 1, which results in a minimum thickness of the first end cover 1, which cannot be less than the minimum thickness that can be tapped. For this reason, this embodiment partially thickens the first end cover 1 to form a thickened portion 11, and the thickened portion 11 is thicker than the rest of the first end cover 1, such as the thinned portion, which can meet the tapping requirements. For another example, the first end cover 1 and the second end cover 2 are surrounded to form a cavity 3. Often, the distance between the thickened portion 11 and the second end cover 2 is smaller than the distance between the rest of the first end cover 1 and the second end cover 2, which results in the cavity 3 being partially spacious and partially narrow, which is conducive to achieving the realization of clamping the electric control device in a narrow space and meeting the wiring, heat dissipation and maintenance of the electric control device in a spacious space. For another example, on the basis that the thickened portion 11 meets the installation requirements of the electronic control device, the thinned portion can reduce the weight of the first end cover 1, and also facilitate heat transfer between the motor chamber 011 and the electronic control device, which can improve the heat dissipation effect of the electronic control device, and is beneficial to ensuring the operating performance of the electronic control device.

[0041] In summary, the compressor end shell provided in the present application can provide an independent installation space for the electronic control device, so that the electronic control device can be installed independently of the motor, compression assembly, main shaft and other components of the compressor, which is conducive to simplifying the installation and maintenance of the electronic control device. At the same time, the shape, size and position of this independent installation space can be better matched with the electronic control device, which is conducive to improving the installation performance and operating performance of the electronic control device.

[0042] The compressor end shell provided in the present application is further described below in conjunction with the accompanying drawings and implementation examples.

[0043] In some embodiments, the compressor end shell includes a first end cover 1, an axis mounting portion is provided on one side of the first end cover 1 and a thickened portion 11 is provided on the other end, the axis mounting portion and the thickened portion 11 are respectively extended toward their respective sides, and the first end and the thickened portion 11 are integrally formed with the first end cover 1.

[0044] For reference Figure 1 The middle part of the first end cover 1 faces Figure 1 The left side of the first end cover 1 extends to form a shaft mounting portion, which is used to realize the end positioning of the shaft 01. For example, the shaft 01 refers to the main shaft in the compressor, and the end of the main shaft can be installed in the shaft mounting portion through a bearing; the local edge of the first end cover 1 faces Figure 1 The right side of the first end cover 1 is extended to form a thickened portion 11, which can meet the tapping requirements and can also appropriately reduce the distance between the first end cover 1 and the second end cover 2 at this position, so as to facilitate the placement and restraint of the electronic control device.

[0045] In the above embodiment, the shaft mounting portion can be used to mount the bearing of the main shaft, so the shaft mounting portion can be regarded as the bearing mounting seat 13. Figure 1 As shown, the bearing mounting seat 13 is sleeve-shaped, and the bearing mounting seat 13 is extended from the center of the cover plate of the first end cover 1. For the aforementioned bearing mounting seat 13, it includes a mounting hole and a hole wall surrounding the mounting hole. Since the first end cover 1 separates the motor chamber 011 and the cavity 3, the aforementioned mounting hole is a blind hole. In other words, one end of the mounting hole is through toward one side of the motor chamber 011, and the other end of the mounting hole is non-through toward the cavity 3.

[0046] In the above embodiment, the cavity 3 between the thickened portion 11 and the second end cover 2 can be used to place and constrain the electronic control device. Usually, the thickened portion 11 is offset from the edge of the cover plate of the first end cover 1, and accordingly, the electronic control device is offset in the cavity 3, which is convenient for wiring and maintenance. For example, a power slot is provided on the outer side of the compressor end shell, such as Figure 3 As shown, the outer power supply slot of the second end cover 2 is adjacent to the thickened portion 11 and the electric control device, and the operator can connect the electric control device and the external power supply through the power supply slot.

[0047] Usually, the electric control device can be connected to two power supply slots. For example, the second end cover 2 is provided with two power supply slots. The two power supply slots are respectively arranged on the adjacent sides of the second end cover 2, and are used to install the power supply of the electric control device and the power supply of the compressor motor respectively. Figure 3For example, the electric control device is close to the upper part of the second end cover 2. For this purpose, a power supply slot is provided at the upper end of the second end cover 2. The compressor motor power supply can be installed in the power supply slot. The compressor motor power supply is connected to the motor of the compressor through the electric control device to supply energy to the motor. A power supply slot is provided on the right side of the second end cover 2. The power supply slot can be installed in the power supply slot of the electric control device. The electric control device power supply is connected to the electric control device to supply energy to the electric control device. The electric control device is far away from the lower end of the second end cover 2, so it is not necessary to set a power supply slot under the second end cover 2. In the above example, the two power supply slots are arranged on the adjacent side of the second end cover 2, which can shorten the distance between each and the electric control device, and avoid the power supplies in the two power supply slots being too close to interfere with each other.

[0048] For reference Figure 1 and Figure 2 In some of the embodiments provided above, the thickened portion 11 includes a boss protruding toward the cavity 3, the boss profile of which can match the surface of the electric control device, and the boss is provided with a terminal hole 111 and a tapping hole 112. As the name implies, the terminal hole 111 is a hole for inserting the terminal of the electric control device, and the tapping hole 112 is a hole for inserting the threaded connector of the electric control device. Usually, a plurality of terminal holes 111 and a plurality of tapping holes 112 are provided in the boss, for example, Figure 2 The boss shown is provided with three terminal holes 111 and four tapped holes 112 . The three terminal holes 111 are arranged in parallel in the middle of the boss, and the four tapped holes 112 are arranged around the three terminal holes 111 .

[0049] Since the compressed gas in the motor chamber 011 is clean gas, in order to prevent the clean gas from being contaminated in the cavity 3, the first end cover 1 needs to seal and separate the motor chamber 011 and the cavity 3. For this reason, in the above embodiment, a sealing member is often provided in the tapping hole 112 to ensure the sealing performance of both the motor chamber 011 and the cavity 3. Of course, the terminal hole 111 can also be sealed according to the situation, including but not limited to installing a sealing ring in the terminal hole 111.

[0050] Still available for reference Figure 2 In the above embodiment, the left middle area of ​​the first end cover 1 is set as a boss, and the boss profile of the boss is Figure 2 The rest of the first end cover 1 is a thinning portion 12, and the thinning portion 12 is Figure 2 The middle is roughly crescent-shaped.

[0051] In some of the embodiments provided above, the first end cover 1 may be in the shape of a plate, with a mounting flange 14 provided on its circumferential side; the second end cover 2 may be in the shape of a cylinder, with one end of the second end cover 2 closed and the other end closed and connected to the mounting flange 14, and the end face and circumferential face of the second end cover 2 are connected by a smooth arc surface. The aforementioned first end cover 1 has a small overall size, is easy to process and install, and is convenient for setting a thickened portion 11 and a thinned portion 12 thereon; the aforementioned second end cover 2 has a regular shape and smooth edges, which is conducive to improving the aesthetics of the entire compressor end cover, and is also conducive to improving the installation relationship between the compressor and other equipment. Of course, according to the specific requirements of the compressor and its installation environment, the first end cover 1 and the second end cover 2 can also be designed as other suitable shapes.

[0052] In the above embodiment, based on the basic shape structure and connection relationship between the first end cover 1 and the second end cover 2, the first end cover 1 and the second end cover 2 respectively play different roles in the entire compressor end shell, and different structural parameters can be designed accordingly. For example, the first end cover 1 is mainly used to install the electronic control device and separate the electronic control device from the motor chamber 011, so there is no need to pay too much attention to the smoothness and aesthetics of the appearance of the first end cover 1, nor is it necessary to require the first end cover 1 to have a large anti-deformation ability. On the contrary, the second end cover 2 is cylindrical and forms a surrounding structure on one side of the first end cover 1, which can be regarded as a line of defense for the first end cover 1 to resist external force impact. For this reason, the second end cover 2 needs to have a sufficiently large anti-deformation ability and also needs to have a relatively smooth, smooth and beautiful appearance, which can be achieved by appropriately increasing the thickness of the second end cover 2, selecting a suitable material, and adjusting the local shape of the second end cover 2.

[0053] The present application also provides a compressor housing, including a compressor casing for accommodating a motor and a compression assembly, and also including a compressor end casing provided in the above embodiments; wherein the compressor end casing is arranged at the end of the compressor casing.

[0054] In the above embodiments, the compressor end shell can be arranged at one end of the compressor casing, or at both ends of the compressor casing, which often depends on the shape and structure of the compressor casing itself. For example, if the compressor casing is a semi-enclosed sleeve with one end open and the other end closed, the compressor end shell can be arranged at the open end of the compressor casing to block the open end of the compressor casing. For another example, if the compressor casing is a sleeve with both ends open, the compressor end shell can be arranged at one end or both ends; usually, one compressor is equipped with one electronic control device, so one compressor casing can be connected to one compressor end shell, and the other end of the aforementioned compressor casing can be blocked with an end shell of other shapes.

[0055] For reference Figure 3In some embodiments, the compressor casing includes an intermediate shell 0110 and a compression side end shell 0120; a motor chamber 011 and a compression chamber 012 are provided in the intermediate shell 0110, the motor of the compressor can be installed in the aforementioned motor chamber 011, and the compression assembly of the compressor can be installed in the aforementioned compression chamber 012; the compression side end shell 0120 and the compressor end shell provided in each embodiment of the present invention are respectively arranged at both ends of the intermediate shell 0110, that is, the compression side end shell 0120 is arranged at one end of the intermediate shell 0110, for sealing the compression chamber 012, and the compressor end shell is arranged at the other end of the intermediate shell 0110, for sealing the motor chamber 011.

[0056] In the above embodiment, mounting hole seats 013 are provided on both ends of the intermediate shell 0110. The mounting hole seats 013 protrude toward the outside of the circumferential side of the intermediate shell 0110 and can be used to install fasteners 02. For example, the compression side end shell 0120 and the compressor end shell can be locked to the corresponding mounting hole seats 013 by fasteners 02.

[0057] The present application also provides a compressor, including the compressor housing mentioned above. Other parts of the compressor, such as motors, pumps and other compression components, are arranged in the compressor housing. The specific installation method of the aforementioned parts in the compressor housing can refer to the relevant design of the prior art. This article does not make any improvements to this, so it will not be repeated.

[0058] The compressor, compressor housing and compressor end shell provided by the present application are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
