DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 10 , please refer to Figures 1 to 6 , which shows an embodiment of the compressor end cover 100 provided by the present invention. The structure and working principle of the compressor end cover 100 are described in detail below in conjunction with the drawings in the specification. The compressor end cover 100 includes a wire gathering shell 10, a wire inlet 101 is formed at the bottom of the horizontal side of the compressor end cover 100, and a wire outlet 102 is formed at the top of the compressor end cover 100. The wire inlet 101 and the wire outlet 102 are vertically connected on the inner side of the wire gathering shell 10 to form a wire gathering channel 103; wherein, the wire inlet 101, the wire gathering channel 103, and the wire outlet 102 are sequentially provided for the wiring harness 20 to pass through.

[0032] In a specific implementation, the compressor end cover 100 includes a line gathering shell 10, which is composed of multiple side edges as a whole. The line gathering shell 10 has a line inlet 101 formed at the bottom of the side edge in the horizontal direction. The line inlet 101 is an opening structure or a notch structure set at the bottom of the side edge in the horizontal direction of the line gathering shell 10. The number of line inlets 101 is not limited, and one or more lines can be designed. The line inlet 101 can be set at the bottom of any side edge in the horizontal direction of the line gathering shell 10. The area of the line inlet 101 can be set according to the number of actual wiring harnesses 20 and the size of the wiring harness 20. A wire outlet 102 is formed at the top of the wire gathering shell 10. The wire outlet 102 is an opening structure or a notch structure set on the top of the wire gathering shell 10. The wire inlet 101 and the wire outlet 102 are connected along the vertical direction on the inner side of the wire gathering shell 10 to form a wire gathering channel 103. The wire gathering channel 103 makes the inner side of the wire gathering shell 10 hollow. The bottom end of the wire gathering channel 103 is connected to the wire inlet 101, and the top end of the wire gathering channel 103 is connected to the wire outlet 102. Normally, the area of the wire outlet 102 is larger than the area of the wire inlet 101, and it can be specifically set according to the number of actual wiring harnesses 20 and the total area of the wire inlet 101. The wire inlet 101, the wire gathering channel 103, and the wire outlet 102 are sequentially provided for the wire harness 20 to pass through, forming a routing path for the wire harness 20. The wire harness 20 can pass through the wire gathering channel 103 on the inner side of the wire gathering shell 10 through the wire inlet 101, and pass through the wire gathering channel 103 from the wire outlet 102 on the top of the wire gathering shell 10. The overall routing path of the wire harness 20 is: wire inlet 101 - wire gathering channel 103 - wire outlet 102. In actual application, the wire harness 20 is introduced horizontally through the wire inlet 101 at the bottom side of the wire gathering shell 10, and the wire harness 20 goes upward along the wire gathering channel 103 on the inner side of the wire gathering shell 10. When there are multiple wire harnesses 20, the multiple wire harnesses 20 are gathered in the wire gathering channel 103 to complete the shaping. All wire harnesses 20 are routed upward in the vertical direction, and finally the wire harness 20 is led out from the wire outlet 102 on the top of the wire gathering shell 10. The wire harness 20 is led out from the outlet 102 at the top of the cable collection housing 10 and then connected to the corresponding terminal or component. Overall, the wiring harness 20 is directed vertically upward. The wiring harness 20 has an orderly and uniform direction, effectively preventing direct contact between the wiring harness 20 and high-temperature components and pipelines on the compressor surface, reducing the risk of high-temperature burns. Furthermore, due to the uniform direction of the wiring harness 20, the length of the wiring harness 20 is shortened, saving material costs.

[0033] The compressor end cover of this embodiment forms a wire inlet at the bottom of the side of the wire gathering shell in the horizontal direction, and forms a wire outlet at the top of the wire gathering shell. The wire inlet and the wire outlet are vertically connected on the inner side of the wire gathering shell to form a wire gathering channel. The wire harness is passed through the wire inlet, the wire gathering channel and the wire outlet in sequence, so that the wire harness can enter the wire gathering channel inside the wire gathering shell from the wire inlet in the horizontal direction and gather, and then be led out from the wire outlet on the top of the wire gathering shell in the vertical direction. The overall direction of the wire harness is upward in the vertical direction, which effectively avoids the wire harness from contacting the compressor surface and pipeline to cause wire harness burns, making the compressor operation more reliable.

[0034] In one embodiment, referring to Figures 1 to 5The line gathering housing 10 has a first side 11 and a second side 12 in the horizontal direction that are adjacent to the line gathering channel 103. The first side 11 and the second side 12 are vertically connected. The bottom of each of the first side 11 and the second side 12 is formed with the line inlet 101, wherein the area of the line inlet 101 on the second side 12 is larger than the area of the line inlet 101 on the first side 11. In a specific implementation, the line gathering housing 10 has a first side 11 and a second side 12 in the horizontal direction that are adjacent to the line gathering channel 103. The first side 11 and the second side 12 are two adjacent side edges of the line gathering housing 10 in the horizontal direction. The first side 11 and the second side 12 are vertically connected, and the inner sides are adjacent to the line gathering channel 103. The shapes of the first side 11 and the second side 12 are arbitrary. Both can be designed as straight sides, curved sides or other irregular sides. A wire inlet 101 is formed at the bottom of the first side 11 and the second side 12. The wire inlet 101 at the bottom of the first side 11 and the second side 12 can be designed as an opening structure or a notch structure. The area of the wire inlet 101 at the bottom of the second side 12 is larger than the area of the wire inlet 101 at the bottom of the first side 11. The area of the wire inlet 101 at the bottom of the first side 11 is smaller, mainly for the insertion of smaller wire harnesses 20, such as the wire harness of the compressor's temperature sensor or the wire harness of other sensors, which are usually relatively small. The wire inlet 101 at the bottom of the first side 11 can be used for the wire harness of the compressor's temperature sensor or the wire harness of other sensors to pass through. The wire inlet 101 at the bottom of the second side 12 is larger in area and is mainly used for the insertion of larger wire harnesses 20. For example, the wire harnesses for the terminal posts of a compressor are usually thicker. The wire inlet 101 at the bottom of the second side 12 can be used for the insertion of the wire harnesses for the terminal posts of the compressor. In actual applications, smaller wire harnesses 20 are inserted from the wire inlet 101 at the bottom of the first side 11, and larger wire harnesses 20 are inserted from the wire inlet 101 at the bottom of the second side 12 into the wire gathering channel 103 on the inside of the shell. The wire harnesses 20 then go upward along the wire gathering channel 103 and are finally led out from the wire outlet 102 at the top of the wire gathering shell 10 at the same time. The overall routing direction of all wire harnesses 20 is in the vertical direction. Wire harnesses 20 of different sizes are led out from the wire outlet 102 at the top of the wire gathering shell 10 and then connected to the corresponding terminal or component. On the whole, the small-sized wiring harness 20 and the large-sized wiring harness 20 are respectively routed through the wiring inlet 101 at the bottom of the first side 11 and the bottom of the second side 12 that are vertically connected. The small-sized wiring harness 20 and the large-sized wiring harness 20 are routed through the corresponding wiring inlet 101 from two different directions, which can avoid the twisting and entanglement of wiring harnesses 20 of different sizes, resulting in a messy wiring harness 20. The routing of the small-sized wiring harness 20 and the large-sized wiring harness 20 is orderly and unified, effectively avoiding direct contact between various wiring harnesses 20 and high-temperature components and pipelines on the surface of the compressor, further reducing the risk of the wiring harness 20 being burned by high temperature.

[0035] Further, refer to Figures 1 to 6 The line gathering housing 10 has a third side 13 adjacent to the line gathering channel 103 in the horizontal direction, the third side 13 is vertically connected to the second side 12 and horizontally opposite to the first side 11, and the line inlet 101 is formed at the bottom of the third side 13, wherein the line inlet 101 on the third side 13 is adjacent to the line inlet 101 on the second side 12, and the area of the line inlet 101 on the third side 13 is greater than or equal to the area of the line inlet 101 on the second side 12. In a specific implementation, the line gathering housing 10 has a third side 13 adjacent to the line gathering channel 103 in the horizontal direction, the third side 13 is vertically connected to the second side 12 on the left and right and horizontally opposite to the first side 11, that is, the third side 13 and the first side 11 are two opposite sides of the line gathering housing 10 in the horizontal direction, and the second side 12 is vertically connected between the third side 13 and the first side 11. The inner side of the third side 13 is adjacent to the wire gathering channel 103, and a wire entry port 101 is also formed at the bottom of the third side 13. The wire entry port 101 at the bottom of the third side 13 is adjacent to the wire entry port 101 at the bottom of the second side 12 to form a larger opening, and the area of the wire entry port 101 at the bottom of the third side 13 is greater than or equal to the area of the wire entry port 101 at the bottom of the first side 11, and can accommodate more and larger wire harnesses 20 for insertion and routing. Large-sized wire harnesses 20 can be inserted and routed from the wire entry port 101 at the bottom of the second side 12 and the wire entry port 101 at the bottom of the third side 13 at the same time. The wiring harness 20 passes through the wire inlet 101 at the bottom of the second side 12 and the wire inlet 101 at the bottom of the third side 13, into the wire converging channel 103 inside the housing, then moves upward along the wire converging channel 103 and finally exits through the wire outlet 102 at the top of the wire converging housing 10. The overall routing direction of the wiring harness 20 is vertical. After exiting the wire outlet 102 at the top of the wire converging housing 10, the wiring harness 20 is connected to the corresponding terminal or component. Overall, large-sized wiring harnesses 20 in different directions can be routed through the wire inlet 101 at the bottom of the third side 13 and the bottom of the second side 12, respectively. This can reduce the horizontal routing distance of the large-sized wiring harness 20 and prevent the wiring harness 20 from being entangled and causing the wiring harness 20 to be messy. The routing of the wiring harness 20 is more orderly and unified, preventing the wiring harness 20 from contacting high-temperature components and pipelines on the compressor surface, further reducing the risk of high-temperature burns caused by the wiring harness 20.

[0036] Furthermore, refer to Figures 1 to 6The line gathering shell 10 has a fourth side 14 adjacent to the line gathering channel 103 in the horizontal direction, the fourth side 14 is connected to the third side 13 and horizontally opposite to the second side 12, and the line inlet 101 is formed at the bottom of the fourth side 14, wherein the line inlet 101 on the fourth side 14 is adjacent to the line inlet 101 on the third side 13 and extends vertically to the top of the line gathering shell 10 and is adjacent to the line outlet 102, and the line inlet 101 on the second side 12 is adjacent to the line inlet 101 on the first side 11. In a specific embodiment, the line gathering housing 10 has a fourth side 14 in the horizontal direction that is adjacent to the line gathering channel 103. The fourth side 14 is horizontally connected to the third side 13 and is horizontally opposite to the second side 12. That is, the fourth side 14 and the second side 12 are two opposite sides of the line gathering housing 10 in the horizontal direction. The second side 12 is connected between the third side 13 and the first side 11. The inner side of the fourth side 14 is adjacent to the line gathering channel 103. Overall, the line gathering channel 103 is enclosed by the first side 11, the second side 12, the third side 13, and the fourth side 14. A line inlet 101 is also formed at the bottom of the fourth side 14. The line inlet 101 at the bottom of the fourth side 14 is adjacent to the line inlet 101 at the bottom of the third side 13 and extends upward in the vertical direction to the top of the line gathering housing 10, adjacent to the line outlet 102. The wire inlet 101 at the bottom of the second side 12 is also adjacent to the wire inlet 101 on the first side 11. Thus, the wire inlets 101 on the first side 11, the second side 12, the third side 13 and the fourth side 14 are adjacent in sequence, forming a winding gap around the surface of the wire gathering shell 10. The starting end of the gap is the wire inlet 101 at the bottom of the first side 11, and the end end of the gap is the wire outlet 102 at the top of the wire gathering shell 10. In actual application, the wiring harness 20 can be directly incorporated into the wire gathering channel 103 on the inner side of the wire gathering shell 10 from the wires along the second side 12, the third side 13 and the fourth side 14, and led out at the wire outlet 102. The wiring arrangement of the wire harness 20 can be easily completed without inserting the ends of the wire harness 20 in sequence, and the wiring arrangement of the wire harness 20 is more convenient.

[0037] In one embodiment, referring to Figures 2 to 5 、 Figure 10The compressor end cover 100 also includes a first shell 30 for accommodating the temperature-sensing package 212. The first shell 30 is provided on one side of the convergence shell 10 in the horizontal direction. A first outlet 301 is provided on one side of the first shell 30. The first outlet 301 is adjacent to the line inlet 101 on the first side 11. In a specific implementation, the compressor end cover also includes a first shell 30. The first shell 30 is mainly used to accommodate the temperature-sensing package 212 of the compressor and provide outer shell protection for the temperature-sensing package 212. The first shell 30 is a cover structure, and the temperature-sensing package 212 can be accommodated on the inner side of the first shell 30. The first shell 30 is provided on one side of the convergence shell 10 in the horizontal direction and is connected to it as a whole. A first outlet 301 is provided on one side of the first shell 30. The first outlet 301 is adjacent to the line inlet 101 at the bottom of the first side 11 of the convergence shell 10. In actual application, after the temperature sensing package 212 of the compressor is housed in the first shell 30, the wiring harness of the temperature sensing package 212 is led out to the outside of the first shell 30 through the first outlet 301 and directly penetrates into the wire inlet 101 at the bottom of the first side 11. The wiring harness of the temperature sensing package 212 is routed upward through the wire gathering channel 103 and led out at the wire outlet 102 at the top of the wire gathering shell 10. Since the first wire outlet 102 is adjacent to the wire inlet 101 at the bottom of the first side 11, the wiring length of the temperature sensing package 212 can be shortened, effectively avoiding contact between the wiring harness of the temperature sensing package 212 and the high-temperature components and pipelines on the surface of the compressor, thereby reducing the risk of the wiring harness of the temperature sensing package 212 being burned by high temperature.

[0038] In one embodiment, referring to Figures 1 to 6 、 Figure 10The compressor end cover 100 further includes a second housing 40 for accommodating the terminal posts 211. The second housing 40 is disposed on one side of the converging housing 10 in the horizontal direction. A second outlet 401 is disposed on one side of the second housing 40, and the second outlet 401 is adjacent to the inlet 101 on the second side 12. In a specific implementation, the compressor end cover further includes the second housing 40. The second housing 40 is primarily used to accommodate the compressor terminal posts 211, providing outer protection for the compressor terminal posts 211. The interior of the second housing 40 includes a chamber for accommodating the terminal posts 211, and the terminal posts 211 can be accommodated in the chamber within the second housing 40. The second shell 40 is arranged on one side of the gathering shell 10 in the horizontal direction and is connected to it. A second outlet 401 is provided on one side of the second shell 40. The second outlet 401 is adjacent to the wire inlet 101 at the bottom of the second side 12 of the gathering shell 10. After the terminal 211 is accommodated in the second shell 40, the wiring harness of the terminal 211 is led out to the outside of the second shell 40 through the second outlet 401 and directly penetrates into the wire inlet 101 at the bottom of the second side 12. The wiring harness of the terminal 211 is routed upward through the gathering channel 103 and led out at the wire outlet 102 at the top of the gathering shell 10. Since the second wire outlet 102 is adjacent to the wire inlet 101 at the bottom of the second side 12, the wiring length of the wiring harness of the terminal 211 can be shortened, effectively avoiding contact between the wiring harness of the terminal 211 and the high-temperature components and pipelines on the surface of the compressor, thereby reducing the risk of the wiring harness of the terminal 211 being burned by high temperature.

[0039] In one embodiment, referring to Figure 2 、 Figure 3 as well as Figure 7 、 Figure 8, the axial cross-sectional area of the line gathering channel 103 is S2, and the area of the line inlet 101 on the first side 11 is S1, wherein 1.3S1≤S2≤1.8S1. In a specific implementation, the line gathering channel 103 extends vertically on the inner side of the line gathering shell 10, the side wall of the line gathering channel 103 is a plane, and the axial cross-section of the line gathering channel 103 is a polygon, including regular polygons and irregular polygons, and the axial cross-section of the line gathering channel 103 can be any one of them. Generally, the larger the axial cross-sectional area of the line gathering channel 103, the more wire harnesses 20 that the line gathering channel 103 can accommodate, and the shape of the line inlet 101 on the first side 11 includes regular shapes and irregular shapes, and the shape of the line inlet 101 on the first side 11 can be any one of them. The wire harness 20 passes through the wire inlet 101 on the first side 11 and the wire inlet 101 on the second side 12 into the wire gathering channel 103 on the inside of the wire gathering shell 10. All wire harnesses 20 are gathered and shaped in the wire gathering channel 103. The wire harnesses 20 are routed upward in the vertical direction and finally led out from the wire outlet 102 on the top of the wire gathering shell 10. As a structure that accommodates all wire harnesses 20, the axial cross-sectional area of the wire gathering channel 103 needs to be designed within a reasonable range. The axial cross-sectional area of the wire gathering channel 103 should be larger than the area of the wire inlet 101 on the first side 11. In this way, when the wire inlet 101 on the first side 11 is full of wire harnesses 20, the wire inlet 101 on the second side 12 can continue to route the wire harness 20. In this embodiment, S2 represents the axial cross-sectional area of the line gathering channel 103, and S1 represents the area of the line inlet 101 on the first side 11. S1 and S2 are designed to satisfy the relationship 1.3S1≤S2≤1.8S1, that is, the axial cross-sectional area of the line gathering channel 103 can be designed to be at least 1.3 times the area of the line inlet 101 on the first side 11, and at most 1.8 times the area of the line inlet 101 on the first side 11. The line gathering channel 103 and the line inlet 101 on the first side 11 are designed according to the relationship 1.3S1≤S2≤1.8S1, the routing of each wiring harness 20 is reasonably optimized, the system line wiring is simple, the routing length of each wiring harness 20 is effectively reduced, and the risk of each wiring harness 20 being scalded by high-temperature components is reduced.

[0040] In one embodiment, referring to Figure 2 、 Figure 3 as well as Figure 7 、 Figure 8 The area of the wire inlet 101 on the first side 11 is S1, the axial cross-sectional area of the wire concentrating channel 103 is S2, and the sum of the axial cross-sectional areas of all the wire harnesses 20 passing through the wire inlet 101 is S n , of which 1.2S n ≤S1+S2≤3S nIn a specific implementation, the wire harness 20 passes through the wire inlet 101 on the first side 11 and the wire inlet 101 on the second side 12 into the wire gathering channel 103 inside the wire gathering housing 10. All wire harnesses 20 are gathered and shaped in the wire gathering channel 103. The wire harnesses 20 are routed upward in the vertical direction and finally led out from the wire outlet 102 at the top of the wire gathering housing 10. The number of wire bundles 20 that can be accommodated in the wire gathering channel 103 is mainly determined by the axial cross-sectional area of the wire gathering channel 103 and the axial cross-sectional area of each wire bundle 20. The axial cross-sectional areas of wire bundles 20 of different sizes are different. When the axial cross-sectional area of the wire gathering channel 103 is fixed, the number of wire bundles 20 with larger axial cross-sectional areas that can be accommodated is less than the number of wire bundles 20 with smaller axial cross-sectional areas. In actual applications, wire bundles 20 of different types and sizes will be accommodated in the wire gathering channel 103 at the same time. The wire gathering channel 103 and the wire inlet 101 can be reasonably designed according to the axial cross-sectional area of the wire bundle 20 to reasonably optimize the routing of the wire bundle 20. In this embodiment, S2 represents the axial cross-sectional area of the wire gathering channel 103, S1 represents the area of the wire inlet 101 on the first side 11, and S n It represents the sum of the axial cross-sectional areas of all the wire harnesses 20 that pass through the wire inlet 101. All the wire harnesses 20 that pass through the wire inlet 101 include large-sized wire harnesses 20 and small-sized wire harnesses 20, such as the wire harness 20 of the compressor terminal and the wire harness 20 of the temperature sensor. n Designed to meet the relationship 1.2S n ≤S1+S2≤3S n , that is, the sum of the axial cross-sectional area of the converging channel 103 and the area of the wire inlet 101 on the first side 11 is designed to be at least 1.2 times the sum of the axial cross-sectional areas of all the wire bundles 20 passing through the wire inlet 101, and at most 3 times the sum of the axial cross-sectional areas of all the wire bundles 20 passing through the wire inlet 101. According to the relationship 1.2S n ≤S1+S2≤3S n The line gathering channel 103 and the line inlet 101 on the first side 11 are designed, and the routing of each wire harness 20 is reasonably optimized. The system line wiring is simple, which effectively reduces the routing length of each wire harness 20 and reduces the risk of each wire harness 20 being burned by high-temperature components.

[0041] In one embodiment, referring to Figure 9 and Figure 10This embodiment provides a compressor cover, which includes a cover body 210 and the compressor end cover 100 described in the above embodiment.

Specifically, the compressor end cover 100 is fixed to the cover body 210 by a bolt 214, and the insulating gasket 213 is arranged between the compressor end cover 100 and the cover body 210. The terminal 211, the temperature-sensitive package 212 and the exhaust pipe are all arranged on the cover body 210, and the temperature-sensitive package 212 is in contact with the exhaust pipe. The wiring harness of the terminal 211 and the temperature sensor 212 and the wiring harness of other electrical components can pass through the wiring inlet 101 at the bottom side of the wiring concentrating shell 10 of the compressor end cover 100 and enter the wiring concentrating channel 103 on the inside of the wiring inlet shell. The wiring harness is routed upward along the wiring concentrating channel 103 and led out from the wiring outlet 102 at the top of the wiring concentrating shell 10. The wiring direction of the wiring harness is vertically upward as a whole. The wiring direction of the wiring harness is orderly and uniform. The wiring length of the wiring harness is shorter and the wiring is neat, which effectively avoids direct contact between the wiring harness and the high-temperature components and pipelines on the surface of the compressor, reducing the risk of the wiring harness being burned by high temperature.
