[0035] The first aspect of this application provides an engine cylinder assembly 10 for a vehicle. Figure 1 This is a schematic diagram of the structure of an embodiment of the engine cylinder assembly 10 of the vehicle provided in this application. Figure 2 yes Figure 1 The diagram shown is a structural illustration from another perspective. Figure 3 yes Figure 1 Top view of the structure shown. Figure 4 yes Figure 1 A schematic diagram of the structure shown from another perspective.

[0036] Combination Figures 1-4 The vehicle's engine cylinder assembly 10 includes a cylinder body 11 and a water pump chamber 12. The cylinder body 11 forms a water jacket cavity 111 for coolant flow. The cylinder body 11 may include a cylinder 112 and a water jacket 113. The cylinder 112 houses the piston, and the water jacket 113 is located outside the cylinder 112, forming a gap between the water jacket 113 and the cylinder 112; this gap is the water jacket cavity 111. The coolant within the water jacket cavity 111 can change temperature; when the coolant flows within it, it can cool or heat the cylinder 112 and related components.

[0037] The cylinder body 11 is provided with a first flow port 114 and a second flow port (not shown) that are respectively connected to the water jacket cavity 111. The first flow port 114 and the second flow port can be provided on the side wall 124 of the cylinder body 11. The first flow port 114 and the second flow port are used to connect with external components outside the cylinder body 11, so as to realize the circulation of coolant in the water jacket cavity 111 through the external components.

[0038] Furthermore, the water pump cavity 12 is disposed on the cylinder body 11. The water pump cavity 12 can be integrated into the cylinder body 11, which can be achieved by integral molding. The water pump cavity 12 forms a water pump chamber 121 communicating with the first flow port 114, combined with... Figure 1 The first flow port 114 is located on the side of the cylinder body 11 where the water pump chamber 12 is located, and the second flow port can be located on the side of the cylinder body 11 opposite to the first flow port 114.

[0039] It should be understood that a power structure (not shown) may be disposed within the water pump chamber 12. The power structure may be disposed within the water pump chamber 12, thereby drawing coolant from the vehicle's water tank into the water pump chamber 12. The vehicle's engine cylinder assembly 10 may also include a sealing structure, which cooperates with the water pump chamber 12 to form a sealed space, in which the power structure is located.

[0040] The water pump chamber 12 has a circulation channel 122 inside its cavity wall. The first end of the circulation channel 122 connects to the water pump chamber 121 and then to the water jacket chamber 111 via a first flow port 114. At this time, the coolant in the water jacket chamber 111 can enter the water pump chamber 121 through the first flow port 114, and the coolant in the water pump chamber 121 can enter the circulation channel 122 through its first end. The second end of the circulation channel 122 connects to a second flow port via a connecting structure, thereby realizing the circulation of coolant in the water jacket chamber 111. The connecting structure can be a connecting pipe, a plate structure, etc., allowing the coolant in the circulation channel 122 to enter the second flow port through the connecting structure and then flow back to the water jacket chamber 111 through the second flow port.

[0041] Figure 5 This is a schematic diagram of a cylinder assembly setup.

[0042] like Figure 5 As shown, the water pump 20 is installed on one side of the cylinder body, which occupies a considerable amount of space along with the water pump 20 and related mounting structures. Furthermore, the small circulation pipe 30, in order to connect with the water pump 20, needs to be quite long, with a complex routing and numerous bends, resulting in significant vibration and potential water leakage at the installation point. In contrast, the engine cylinder assembly 10 of the vehicle provided in the above embodiment integrates the water pump 20 and cylinder 112 by placing the water pump chamber 12 on the cylinder body 11, reducing the required installation space. Moreover, the water pump chamber 12 integrates a flow channel, simplifying the installation of the small circulation pipe 30 and further reducing installation space and minimizing vibration and water leakage issues.

Figure 8 yes Figure 7 Enlarged structural diagram of region B in the middle. Figure 9 yes Figure 1 Another side view of the structure shown. Figure 10 yes Figure 9 The structure shown is a cross-sectional view along section line BB. Figure 11 yes Figure 10 An enlarged structural diagram of region C in the diagram.

[0044] Combination Figures 6-11 In some specific embodiments, the circulation channel 122 includes a first channel 1221 and a second channel 1222 that are interconnected. The pump chamber 12 includes a bottom wall 123 and a side wall 124. The first channel 1221 is disposed in the bottom wall 123, and the second channel 1222 is disposed in the side wall 124. One end of the first channel 1221 is connected to the pump chamber 121.

[0045] By dividing the circulation channel 122 into two types of channels, the circulation channel 122 can be simultaneously installed on the bottom wall 123 and side wall 124 of the pump chamber 12, thereby making the arrangement of the circulation channel 122 more in line with actual needs and reducing the need for the small circulation pipe 30.

[0046] Combination Figure 11 In some specific embodiments, the first flow channel 1221 includes a first sub-flow channel 1222a and a second sub-flow channel 1222b that are interconnected. The first sub-flow channel 1222a is connected to the second flow channel 1222, and the second sub-flow channel 1222b is connected to the water pump cavity 12. In this case, the coolant in the second flow channel 1222 can flow into the first sub-flow channel 1222a, then into the second sub-flow channel 1222b, and finally into the water pump cavity 121. Both the first sub-flow channel 1222a and the second sub-flow channel 1222b can be straight channels, with the first sub-flow channel 1222a extending horizontally on the bottom wall 123 and the second sub-flow channel 1222b extending vertically on the bottom wall 123.

[0047] Regarding the specific configuration of the water pump chamber 121, combined with Figure 6 as well as Figure 11 In some specific embodiments, the sidewall 124 encloses to form a first cavity 1211, and the bottom wall 123 is hollowed out to form a second cavity 1212. The first cavity 1211 and the second cavity 1212 constitute a water pump cavity 121. The first cavity 1211 is connected to the first flow port 114, and the second cavity 1212 is connected to one end of the first flow channel 1221.

[0048] Specifically, the sidewall 124 surrounds the bottom wall 123, thus forming a first cavity 1211 together with the bottom wall 123. The bottom wall 123 is hollowed out to form a through hole, which constitutes a second cavity 1212. It should be understood that the first cavity 1211 and the second cavity 1212 can be arranged along the cylinder arrangement direction d of the cylinders 112 in the cylinder body 11, and a sealing structure can be provided on the side of the first cavity 1211 and the second cavity 1212 that is far away from each other, so that the first cavity 1211 and the second cavity 1212 constitute a closed space.

[0049] Combination Figure 3 and Figure 6In some specific embodiments, the bottom wall 123 extends horizontally in the direction of cylinder arrangement d within the vertical cylinder body 11, and the first sub-flow channel 1222a is located on the side of the second flow channel 1222 away from the cylinder 112 in the extension direction of the bottom wall 123. With this arrangement, the second flow channel 1222 is located close to the cylinder body 11, and the first sub-flow channel 1222a is located on the side of the second flow channel 1222 away from the cylinder body 11. At this time, the connection position between the second sub-flow channel 1222b and the water pump chamber 121 is located on the side of the second flow channel 1222 away from the cylinder body 11.

[0050] Regarding the specific arrangement of the first flow channel 1221 and the second flow channel 1222, in some specific embodiments, the extension direction of the second flow channel 1222 is consistent with the arrangement direction of the cylinders 112 in the cylinder body 11, and the extension direction of the first sub-flow channel 1222a is perpendicular to the extension direction of the second flow channel 1222, so that the second flow channel 1222 is perpendicular to the first sub-flow channel 1222a.

[0051] Combination Figure 11 In some specific embodiments, the bottom wall 123 of the water pump cavity 12 is provided with a horizontally extending blind guide hole, which penetrates the side of the bottom wall 123 away from the cylinder body 11. The side wall 124 of the water pump cavity 12 is provided with a vertically extending guide hole, the top of which communicates with the water pump cavity 121, specifically with the second cavity 1212, and the bottom of which penetrates the bottom wall 123. In this case, the blind guide hole and the guide hole intersect to communicate and form a cross-shaped structure. The portion of the blind guide hole away from the guide hole forms a first sub-flow channel 1222a, and the portion of the guide hole away from the blind guide hole forms a second sub-flow channel 1222b.

[0052] Figure 12 yes Figure 4 An enlarged structural diagram of region A.

[0053] Combination Figure 11 and Figure 12 At this time, due to the processing, the first port 125 at one end of the guide hole and the second port 126 at one end of the guide blind hole can be provided with plugs, thereby achieving sealing through the plugs and preventing coolant from leaking from the ports.

[0054] Regarding the configuration of the cylinder body 11, combined with Figure 3In some specific embodiments, in the arrangement direction of the plurality of cylinders 112 of the cylinder body 11, the water pump chamber 12 is disposed at one end of the cylinder body 11 in the arrangement direction. This arrangement ensures that the water pump chamber 12 does not occupy the space in the middle of the side wall 124 of the cylinder body 11, thereby facilitating the avoidance of other structures and enabling the installation of the cylinder 112 assembly. In the direction perpendicular to the cylinder arrangement direction d of the plurality of cylinders 112 of the cylinder body 11, the water pump chamber 12 is disposed on the side wall 124 of the cylinder body 11 in the arrangement direction. By disposing of the water pump chamber 12 on the side wall 124 of the cylinder body 11, the length of the cylinder body 11 in the cylinder arrangement direction d is not reduced, thereby facilitating the miniaturization of the cylinder 112 assembly.
