Description

Technical Field

[0001] This application relates to the field of air conditioning compressor technology, and in particular to the fixing and tensioning structure of the compressor and the compressor itself. Background Technology

[0002] In the design of cab-mounted tractors, the placement of the air conditioning compressor is a crucial part. To ensure the safety, ease of maintenance, and reliability of the air conditioning compressor during use, it is necessary to design a suitable fixing and tensioning structure and method for the air conditioning compressor, thereby improving its service life and ease of maintenance.

[0003] Specifically, the air conditioning compressor operates by being driven by the rotation of the engine crankshaft via a belt. In actual use, a fixing structure and a tensioning structure are required to ensure the compressor's safety performance. Combined with... Figures 1-3 As shown, the current fixed structure and tensioning structure have the following disadvantages: (1) The fixing method is to support a plate 1' and add a fixing point similar to the compressor on the plate 1'. Specifically, the plate 1' extends towards the compressor and has two spaced support protrusions 2'. The bottom of the compressor passes through the two support protrusions 2' in sequence by the first bolt 3' (the two support protrusions 2' have through holes at corresponding positions), thereby fixing the compressor 4'. This fixing method requires a lot of space on the one hand; on the other hand, it requires high coaxiality of the through holes on the support protrusions 2'. Once the two through holes cannot achieve coaxiality, the connection will be invalid. (2) The air conditioning compressor is tensioned by a crescent plate 5' and by tightening the second bolt 6'. One person needs to pull (swing, pull) the compressor outward, and another person needs to tighten the second bolt 6'. It is difficult to operate when only one person is involved, and the tensioning distance is limited and the flexibility is small. (3) The idler wheel 7' of the air conditioner compressor is fixed by a sheet metal part 8'. The machining error of the sheet metal part can easily affect the flatness of the air conditioner compressor, causing the belt to come off during operation. (4) This air conditioner arrangement is complex in structure and has low safety and high failure rate.

[0004] Therefore, there is an urgent need for a compressor fixing and tensioning structure, as well as a compressor itself, to solve the technical problems existing in the current technology to a certain extent. Utility Model Content

[0023] The following detailed embodiments are provided to aid the reader in gaining a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent upon understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order presented herein; rather, changes that will be apparent upon understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, descriptions of features known in the art may be omitted for clarity and brevity. The features described herein may be implemented in different forms and should not be construed as limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application. Throughout this specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. Conversely, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between. As used herein, the term "and / or" includes any one of the relevant items listed and any combination of any two or more of them. Although terms such as "first," "second," and "third" may be used herein to describe individual components, assemblies, regions, layers, or portions, these components, assemblies, regions, layers, or portions are not limited by these terms. More precisely, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as such in the examples may also be referred to as the second component, assembly, region, layer, or part. For ease of description, spatial relational terms such as “above,” “upper,” “below,” and “lower” may be used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relational terms are intended to include not only the orientation depicted in the drawings but also the different orientations of the device in use or operation. For example, if the device in the drawings is flipped, an element described as being “above” or “upper” relative to another element will subsequently be “below” or “lower” relative to that other element.Therefore, the term "above" includes both "above" and "below" depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., oscillating 90 degrees or in other orientations), and the spatial relational terms used herein will be interpreted accordingly. The terminology used herein is for describing various examples only and is not intended to limit this disclosure. Unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. The terms "comprising," "including," and "having" enumerate the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof. Variations in the shapes shown in the figures may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the figures but include changes in shape that occur during manufacturing. The features of the examples described herein may be combined in various ways that will be apparent upon understanding the disclosure of this application. Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible as will be apparent upon understanding the disclosure of this application.

[0024] Example 1 Combination Figures 1-3 The current fixing and tensioning structures have the following disadvantages: (1) The fixing method is to support a plate 1', and add a fixing point similar to the compressor on the plate 1'. Specifically, the plate 1' extends towards the compressor and has two spaced support protrusions 2'. The bottom of the compressor is fixed by passing through the two support protrusions 2' in sequence with the first bolt 3' (the two support protrusions 2' have through holes at corresponding positions). This fixing method requires a lot of space on the one hand; on the other hand, the coaxiality of the through holes on the support protrusions 2' is very important. Once the two through holes cannot achieve coaxiality, the connection will be invalid. (2) The air conditioning compressor 5 is tensioned by a crescent plate 5' and by tightening the second bolt 6'. One person needs to pull the compressor outward and another person needs to tighten the second bolt 6'. It is difficult to operate with one person and the tensioning distance is limited, resulting in low flexibility. In view of the above problems, this application provides a compressor fixing and tensioning structure, which is described below in conjunction with Figures 4-14 The structure will be described in detail.

[0025] The compressor's fixing and tensioning structure includes a support assembly 1, which can be fixed to the engine 6. The support assembly 1 has at least two spaced-apart mounting positions. Specifically, combined with... Figure 9 As shown, the support assembly 1 includes a first support portion 101 and a vertical component (here, the vertical direction refers to the direction in which the support portion 101 is aligned with the vertical component) in the vertical direction. Figure 8The first support 101 and the second support 102 are connected to the engine 6 via connecting members 103, which are optional connecting members 103, i.e., the first support 101 and the second support 102 are fixed to the engine 6 via connecting bolts. An installation space 104 for installing the compressor 5 is provided between the first support 101 and the second support 102; a first mounting position 105 is formed on the first support 101 at a first preset position, and a second mounting position 106 is formed on the second support 102 at a second preset position.

[0026] Furthermore, the first support portion 101 includes a first support plate 107 and a second support plate 108; wherein the first support plate 107 and the second support plate 108 are connected at a first preset angle, optionally, the first preset angle is 90°, that is, the first support plate 107 and the second support plate 108 are connected perpendicularly.

[0027] The first support plate 107 is connected to the engine 6 by connecting bolts. Optionally, the first support plate 107 has a first connecting hole at one end away from the second support part 102, and a second connecting hole is opened on the engine 6 at a position corresponding to the first connecting hole. The connecting bolt passes through the first connecting hole and is threaded into the second connecting hole, thereby fixing the first support plate 107 to the engine 6.

[0028] The second support plate 108 has a first mounting position 105 formed at a first preset position. This first preset position refers to an appropriate location on the second support plate 108 that does not interfere with the installation of other components on the engine 6. Preferably, the first mounting position 105 is a first mounting hole, meaning a first mounting hole is provided at an appropriate position on the second support plate 108. It is worth noting that the first preset position can be adjusted appropriately depending on the specific engine model 6.

[0029] Furthermore, it still combines Figure 9 As shown, the first support plate 107 and the second support plate 108 have a bent structure at the ends opposite to the second support part 102. This bent structure provides a certain amount of redundant space, which makes it possible to install other components on the engine 6.

[0030] Furthermore, it still combines Figure 9 As shown, the second support portion 102 includes a third support plate 109 and a fourth support plate 110; wherein the third support plate 109 and the fourth support plate 110 are connected at a second preset angle; optionally, the second preset angle is 90°, that is, the third support plate 109 and the fourth support plate 110 are connected perpendicularly.

[0031] The third support plate 109 is connected to the engine 6 via a connector 103. Optionally, the third support plate 109 has a third connecting hole at one end away from the first support part 101, and a fourth connecting hole is opened on the engine 6 at a position corresponding to the third connecting hole. The connecting bolt passes through the third connecting hole and is threaded into the fourth connecting hole, thereby fixing the third support plate 109 to the engine 6.

[0032] The fourth support plate 110 has a second mounting position 106 formed at a second preset position. This second preset position refers to an appropriate location on the fourth support plate 110 that does not interfere with the installation of other components on the engine 6. Preferably, the second mounting position 106 is a second mounting hole, i.e., a second mounting hole is provided at an appropriate position on the fourth support plate 110. It is worth noting that the aforementioned second preset position can be adjusted appropriately depending on the specific engine model 6.

[0033] In addition, the first support plate 107, the second support plate 108 and the fourth support plate 110 surround the aforementioned installation space 104.

[0034] Combination Figure 10 and Figure 11 As shown, the fixing and tensioning structure of the compressor 5 also includes a tensioning assembly 2, which has a positioning part 201, a threaded tie rod part 202, and a nut part 203. One end of the threaded tie rod part 202 along its axial direction is rotatably connected to the first mounting position 105; combined with... Figure 11 As shown, optionally, a connecting pin 111 is interference-fitted on the first mounting position 105, and one end of the threaded tie rod 202 along its axial direction is sleeved on the connecting pin 111 and can be rotatably connected to the connecting pin 111.

[0035] One end of the positioning part 201 is fixedly mounted on the compressor 5, and the other end can be sleeved on the threaded tie rod part 202; combined with Figure 11 As shown, optionally, one end of the positioning part 201 extends toward the compressor 5 with a first fixing ear 210, and the compressor 5 extends toward the positioning part 201 with a second fixing ear 211. The first fixing ear 210 and the second fixing ear 211 are connected by a fixing pin 212, and the first fixing ear 210 can rotate around the fixing pin 212 (the fixing pin 212 can cooperate with a fixing nut; when the fixing nut is locked on the positioning pin, a rigid connection between the compressor 5 and the positioning block 204 can be ensured). Optionally, the positioning part 201 is a positioning block 204, and the positioning block 204 is a sleeve that can be fitted onto the threaded tie rod part 202. It is worth noting that the shape of the positioning block 204 is not specifically limited; various shapes of positioning blocks 204 can be used depending on the size of the space and the requirements for aesthetics.

[0036] The threaded portions are respectively disposed on the threaded tie rod portion 202 and located on both sides of the positioning portion 201. Optionally, the nut portion 203 includes a first nut 206 and a second nut 207; optionally, the threaded tie rod portion 202 is a threaded tie rod 205; the first nut 206 and the second nut 207 are respectively threadedly connected to both sides of the positioning portion 201 on the threaded tie rod 205.

[0037] In the actual installation process, firstly, tighten the first nut 206, spring washer 208, and gasket 209, allowing the positioning block 204 to move freely within the threaded rod 205. Then, fix the positioning block 204 to the compressor 5, and then tension the compressor 5's belt. Tighten the nut tightened before the first nut 206 to prevent the tensioned belt from loosening. Finally, tighten the second nut 207, spring washer 208, and gasket to secure the compressor 5. This method requires no two people to operate, making disassembly and maintenance convenient.

[0038] Specifically, the tensioning assembly 2 also includes a spring pad 208; spring pads 208 are provided between the first nut 206 and the positioning block 204 and between the second nut 207 and the positioning block 204; the spring pads 208 have a shock absorption function, and increase the friction force through the reverse elastic force generated by compression, so as to prevent the overall stability of the tensioning assembly 2 from being damaged by the vibration of the compressor 5.

[0039] Specifically, the tensioning assembly 2 also includes gaskets; gaskets are provided between the spring washer 208 and the first nut 206 and between the spring washer 208 and the second nut 207; the gaskets have the function of dispersing pressure to a certain extent and can serve as a pressure buffer layer to expand the force-bearing area, thereby preventing the tensioning assembly 2 from deforming as a whole.

[0040] Combination Figure 10 and Figure 11 As shown, the fixing and tensioning structure of the compressor 5 also includes a fixing component 3, which is cylindrical and is located at the second mounting position 106 of the support component 1. The fixing component 3 is coaxial with the connecting part 501 of the compressor 5, and the compressor 5 can be fixed to the fixing component 3 by the locking member 301.

[0041] Specifically, the fixing component 3 is a fixing cylinder 302, which has a cylindrical structure. The fixing cylinder 302 is disposed at the second mounting position 106, and optionally, the fixing cylinder 302 is fixedly connected to the fourth support plate 110. Furthermore, the fixing cylinder 302 is coaxial with the connecting portion 501 of the compressor 5. In actual use, the locking member 301 passes through the connecting portion 501 and the fixing cylinder 302 in sequence to fix the compressor 5 to the fixing cylinder 302.

[0042] Furthermore, in combination Figure 14As shown, the connecting part 501 is a connecting lug 502, and there are two connecting lugs 502 (connecting lug 303 and connecting lug 304). An installation gap is formed between the two connecting lugs 502, and the fixing cylinder 302 is set in the installation gap. The locking part 301 is a locking bolt and a locking nut. The locking bolt passes through the connecting lug 303, the fixing cylinder 302 and the connecting lug 304 in sequence. After passing through the connecting lug 304, the locking nut is screwed onto the locking bolt, thereby fixing the compressor 5 to the fourth support plate 110.

[0043] It is worth noting that the fixed cylinder 302 can rotate around the screw of the locking nut to accommodate the rotation of the first fixed ear 210 and the second fixed ear 211 on the fixed pin 212, and can also accommodate the rotation of the threaded tie rod 205 on the second support plate 108.

[0044] In summary, the compressor 5 and the fourth support plate 110 are fixed using a fixed cylinder 302. This only requires that the first connecting lug 303 and the hole in the fixed cylinder 302 correspond, and the second connecting lug 304 and the hole in the fixed cylinder 302 correspond, meaning the two fixing points must be aligned. Compared to the existing method where the through holes of the two support protrusions 2' extending from the plate 1' towards the compressor 5 need to be coaxially aligned with the through holes of the two support protrusions 2' extending from the compressor 5 towards the plate 1' (resulting in a total of three fixing points), the above-mentioned arrangement in this application reduces the number of fixing points, resulting in higher coaxiality between the compressor 5 and the fourth support plate 110. Furthermore, during the connection process, the locking nut can directly pass through the fixed cylinder 302; in other words, the locking nut is located inside the fixed cylinder 302. This prevents the mismatch between the holes (the existing through holes of the support protrusions 2') during installation, thus making tensioning smoother.

[0045] In this embodiment, the fixing and tensioning structure of the compressor 5 also includes a casting 4, which supports the idler wheel of the compressor 5. Specifically, the casting 4 is a metal-formed object obtained by injecting smelted liquid metal into a mold through methods such as pouring, injection, or suction, followed by cooling and solidification, and then processing such as grinding. Furthermore, the casting 4 can be of any shape, and the machining accuracy of the holes opened on the casting 4 is easy to control, preventing inconsistent accuracy between each part.

[0046] In addition, casting 4 has a better grasp of dimensions, making it less likely that the compressor belt 5 will fall off due to flatness issues.

[0047] Example 2 This application also provides a compressor, including the aforementioned compressor fixing and tensioning structure. Therefore, it possesses all the beneficial effects of the compressor fixing and tensioning structure, which will not be specifically elaborated here.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
