[0033] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0034] Reference below Figure 1-Figure 7 The cylinder head cover 1 according to the embodiment of the present invention is described. The cylinder head cover 1 can be arranged on a vehicle to cover the cylinder head 201 .

[0035] like Figure 1 and Figure 2 As shown, the cylinder head cover 1 comprises a cover body 10. The cover body 10 is the main body of the cylinder head cover 1, mainly serving as a cover, and also serving as a mounting function.

[0036] like Figure 1 and Figure 2 As shown, in the first direction, the cover body 10 has an intake side 11 and an exhaust side 13, the intake side 11 is provided with a first timing positioning mounting portion 12, and the exhaust side 13 is provided with a second timing positioning mounting portion 14, and in the second direction, the first timing positioning mounting portion 12 and the second timing positioning mounting portion 14 are arranged at intervals, and the first direction is arranged perpendicular to the second direction. Among them, the intake side 11 is the side where air enters the interior of the engine 2, and the exhaust side 13 is the side where air is discharged from the interior of the engine 2 to the outside.

[0037] The first timing positioning installation part 12 and the second timing positioning installation part 14 can both play the role of installation, and the corresponding timing positioning tools can be installed and matched at the first timing positioning installation part 12 and the second timing positioning installation part 14 respectively. It should be noted that the timing positioning tool is mainly used to calibrate the position of the corresponding components inside the engine 2, so that the engine 2 can work better. Specifically, the timing positioning tool can perform timing positioning on the camshaft, improve the assembly accuracy of the camshaft, and thus improve the assembly accuracy of the engine 2.

[0038] The first timing positioning installation part 12 is arranged on the intake side 11, so that the distance between the timing positioning tool matched with the first timing positioning installation part 12 and the camshaft of the intake side 11 can be shortened, thereby facilitating the positioning and matching between the timing positioning tool and the camshaft of the intake side 11. Similarly, the second timing positioning installation part 14 is arranged on the exhaust side 13, so that the distance between the timing positioning tool matched with the second timing positioning installation part 14 and the camshaft of the exhaust side 13 can be shortened, thereby facilitating the positioning and matching between the timing positioning tool and the camshaft of the exhaust side 13.

[0039] In the second direction, the first timing positioning installation part 12 is spaced apart from the second timing positioning installation part 14. This arrangement is more reasonable, avoiding interference between the first timing positioning installation part 12 and the second timing positioning installation part 14, thereby facilitating the installation of the corresponding timing positioning tool. Moreover, the first timing positioning installation part 12 is spaced apart from the second timing positioning installation part 14, so that other corresponding components on the cylinder head cover 1 can also be avoided.

[0040] Therefore, by setting the first timing positioning mounting portion 12 on the intake side 11 and the second timing positioning mounting portion 14 on the exhaust side 13, the camshafts at the intake side 11 and the exhaust side 13 can be timing positioned respectively, thereby improving the assembly accuracy of the engine 2 and allowing the engine 2 to work better. Moreover, the first timing positioning mounting portion 12 and the second timing positioning mounting portion 14 are spaced apart from each other, which makes it easy to avoid other corresponding components of the cylinder head cover 1 and facilitates setting and arrangement.

[0041] In addition, if Figure 1 and Figure 2 As shown, compared with the first timing positioning mounting portion 12, the second timing positioning mounting portion 14 is arranged close to the rear end of the engine 2. It should be noted that the second direction is the front-rear direction of the engine 2, that is, in the second direction, the second timing positioning mounting portion 14 is located at the rear end of the first timing positioning mounting portion 12. Specifically, in the second direction, the second timing positioning portion 31 and the first timing positioning mounting portion 12 are staggered. Due to actual working conditions, the second timing positioning mounting portion 14 needs to avoid corresponding components. Therefore, in the second direction, the second timing positioning mounting portion 14 is arranged at the rear end of the first timing positioning mounting portion 12. This arrangement is more reasonable and convenient for the arrangement and arrangement of corresponding components.

[0042] In addition, if Figure 5As shown, the cover body 10 is also provided with an oil pressure valve mounting portion 15 on the exhaust side 13. In the second direction, the oil pressure valve mounting portion 15 is located at the front end of the second timing positioning mounting portion 14. Among them, the oil pressure valve mounting portion 15 mainly plays the role of installation, and the oil pressure valve mainly plays the role of controlling the circulation of oil. According to the actual working conditions, in the second direction, the oil pressure valve mounting portion 15 is arranged at the front end of the second timing positioning mounting portion 14, so that the oil pressure valve can control the amount of oil entering the corresponding components. It should be noted that in the second direction, the second timing positioning mounting portion 14 is staggered with the first timing positioning mounting portion 12, and the second timing positioning mounting portion 14 is located at the rear end of the first timing positioning mounting portion 12. This arrangement is mainly to avoid the oil pressure valve and facilitate the installation and setting of the oil pressure valve.

[0043] Furthermore, if Figure 5 As shown, the first timing positioning mounting portion 12 is provided with a first mounting hole 121 and a second mounting hole 122, and the second timing positioning mounting portion 14 is provided with a third mounting hole 141 and a fourth mounting hole 142. In the second direction, the first mounting hole 121 and the second mounting hole 122 are arranged at intervals, and the third mounting hole 141 and the fourth mounting hole 142 are located on the same straight line. Among them, the first mounting hole 121 and the second mounting hole 122 can both play the role of installation. In the second direction, the first mounting hole 121 and the second mounting hole 122 are arranged at intervals, so that the arrangement is more reasonable, and interference between the first mounting hole 121 and the second mounting hole 122 can be avoided, which is convenient for the processing and setting of the first mounting hole 121 and the second mounting hole 122. The first mounting hole 121 and the second mounting hole 122 can be better adapted to the corresponding timing positioning tool. Moreover, the position setting of the first mounting hole 121 and the second mounting hole 122 can also play a role of avoidance to a certain extent, which is convenient for the setting and arrangement of other corresponding components.

[0044] Similarly, the third mounting hole 141 and the fourth mounting hole 142 can both play a role in installation. In the second direction, the third mounting hole 141 and the fourth mounting hole 142 are located on the same straight line, that is, the line between the third mounting hole 141 and the fourth mounting hole 142 is parallel to the first direction. This arrangement is more reasonable and can better match the corresponding timing positioning tool according to the actual working conditions. Moreover, the position setting of the third mounting hole 141 and the fourth mounting hole 142 can also play a role of avoidance to a certain extent, which is convenient for the setting and arrangement of other corresponding components.

[0045] Specifically, the cylinder head cover 1 further includes: a first camshaft 20 and a second camshaft 30, the intake side 11 is further provided with a first camshaft mounting hole 16, the exhaust side 13 is provided with a second camshaft mounting hole 17, the first camshaft 20 is rotatably disposed in the first camshaft mounting hole 16, the second camshaft 30 is rotatably disposed in the second camshaft mounting hole 17, the first timing positioning mounting portion 12 is disposed adjacent to the first camshaft mounting hole 16, and the second timing positioning mounting portion 14 is disposed adjacent to the second camshaft mounting hole 17. That is, the above-mentioned camshaft includes the first camshaft 20 and the second camshaft 30.

[0046] Among them, both the first camshaft 20 and the second camshaft 30 can play a role in controlling the opening and closing of the valve. The first camshaft 20 is set on the intake side 11, and the first camshaft 20 is rotatably set in the first camshaft mounting hole 16, so that the first camshaft 20 can control the opening and closing of the valve on the intake side 11 by its own rotation. Similarly, the second camshaft 30 is set on the exhaust side 13, and the second camshaft 30 is rotatably set in the second camshaft mounting hole 17, so that the second camshaft 30 can control the opening and closing of the valve on the exhaust side 13 by its own rotation. In this way, the engine 2 can work normally.

[0047] The first timing positioning installation part 12 is arranged adjacent to the first camshaft installation hole 16, which is more reasonable. When the corresponding timing positioning tool is installed on the first timing positioning installation part 12, the distance between the corresponding timing positioning tool and the first camshaft 20 can be shortened, so that the corresponding timing positioning tool can perform timing positioning operations on the first camshaft 20. Similarly, the second timing positioning installation part 14 is arranged adjacent to the second camshaft installation hole 17. When the corresponding timing positioning tool is installed on the second timing positioning installation part 14, the distance between the corresponding timing positioning tool and the second camshaft 30 can be shortened, so that the corresponding timing positioning tool can perform timing positioning operations on the second camshaft 30.

[0048] In addition, the cylinder head cover 1 also includes: a first camshaft limit regulator and a second camshaft 30 limit regulator, the first camshaft limit regulator is connected to the first camshaft 20, and the second camshaft 30 limit regulator is connected to the second camshaft 30. Among them, the first camshaft limit regulator and the second camshaft 30 limit regulator can both play a regulating role. Specifically, the first camshaft limit regulator can adjust the phase of the first camshaft 20, so as to adjust the position of the first camshaft 20, and then facilitate the timing positioning operation of the first camshaft 20. Similarly, the second camshaft 30 limit regulator can adjust the phase of the second camshaft 30, so as to adjust the position of the second camshaft 30, and then facilitate the timing positioning operation of the second camshaft 30. It should be noted that the above-mentioned oil pressure valve mainly controls the amount of oil entering the second camshaft 30 limit regulator.

[0049] Specifically, the first camshaft limit adjuster is an electric camshaft limit adjuster. Since the control accuracy of the phase of the first camshaft 20 close to the intake side 11 is relatively high, the first camshaft limit adjuster adopts an electric camshaft limit adjuster. This arrangement is more reasonable and can more accurately adjust the phase of the first camshaft 20, thereby improving the accuracy of timing positioning. And because the electric camshaft limit adjuster does not require oil pressure valve oil control, the electric camshaft limit adjuster can be set relatively forward in the second direction. The control accuracy requirement for the phase of the second camshaft 30 close to the exhaust side 13 is not high, and the second camshaft 30 limit adjuster does not need to adopt an electric structure.

[0050] In addition, if Figure 1 and Figure 2 As shown, the intake side 11 is further provided with a first timing positioning opening 18, the first timing positioning opening 18 is communicated with the first camshaft mounting hole 16, the first timing positioning installation portion 12 is arranged adjacent to the first timing positioning opening 18, and the exhaust side 13 is further provided with a second timing positioning opening 19, the second timing positioning opening 19 is communicated with the second camshaft mounting hole 17, and the second timing positioning installation portion 14 is arranged adjacent to the second timing positioning opening 19. Among them, the first timing positioning opening 18 and the second timing positioning opening 19 can both play the role of penetration and matching.

[0051] The first timing positioning opening 18 is connected to the first camshaft mounting hole 16, that is, the corresponding timing positioning tool can pass through the first timing positioning opening 18 and the first camshaft mounting hole 16 to cooperate with the first camshaft 20, so as to realize the timing positioning operation of the first camshaft 20. The first timing positioning installation part 12 is arranged adjacent to the first timing positioning opening 18, which is more reasonable and can shorten the distance between the timing positioning tool and the first camshaft 20 that cooperate with the first timing positioning installation part 12, so as to facilitate the corresponding timing positioning tool to pass through the first timing positioning opening 18 and the first camshaft mounting hole 16 to cooperate with the first camshaft 20 for timing positioning.

[0052] Similarly, the second timing positioning opening 19 is connected to the second camshaft mounting hole 17, that is, the corresponding timing positioning tool can pass through the second timing positioning opening 19 and the second camshaft mounting hole 17 to cooperate with the second camshaft 30, so as to realize the timing positioning operation of the second camshaft 30. The second timing positioning mounting portion 14 is arranged adjacent to the second timing positioning opening 19, which is more reasonable and can shorten the distance between the timing positioning tool that cooperates with the second timing positioning mounting portion 14 and the second camshaft 30, so as to facilitate the corresponding timing positioning tool to pass through the second timing positioning opening 19 and the second camshaft mounting hole 17 to cooperate with the second camshaft 30 for timing positioning.

[0053] It should be noted that, in the second direction, six camshaft bearing seats are provided on the intake side 11 from front to back, and the position of the first timing positioning port 18 is preferably selected between the first cam bearing seat and the second cam bearing seat.

[0054] Furthermore, if Figure 3 and Figure 4 As shown, the first camshaft 20 is provided with a first timing positioning portion 21, and the first timing positioning portion 21 is arranged opposite to the first timing positioning port 18, and the second camshaft 30 is provided with a second timing positioning portion 31, and the second timing positioning portion 31 is arranged opposite to the second timing positioning port 19. Among them, the first timing positioning portion 21 mainly plays a role of positioning and matching. The first timing positioning portion 21 is arranged opposite to the first timing positioning port 18, so that the timing positioning tool matched with the first timing positioning portion 21 can directly pass through the first timing positioning port 18 to match with the first timing positioning portion 21, so as to facilitate the timing positioning operation of the first camshaft 20 by the corresponding timing positioning tool.

[0055] Similarly, the second timing positioning portion 31 also plays a major role in positioning and matching. The second timing positioning portion 31 is arranged opposite to the second timing positioning opening 19, so that the timing positioning tool matched with the second timing positioning portion 31 can directly pass through the second timing positioning opening 19 to match with the second timing positioning portion 31, thereby facilitating the timing positioning operation of the first camshaft 20 by the corresponding timing positioning tool.

[0056] Specifically, Figure 3 and Figure 4 As shown, the first timing positioning portion 21 and the second timing positioning portion 31 both have a first timing positioning surface 211 and a second timing positioning surface 311 that are relatively arranged. When the first timing positioning surface 211 and the second timing positioning surface 311 are both parallel to the third direction, the timing positioning tool is clamped on the first timing positioning surface 211 and the second timing positioning surface 311, and the first direction, the second direction and the third direction are arranged perpendicularly to each other.

[0057] Among them, the first timing positioning surface 211 and the second timing positioning surface 311 can both play the role of timing positioning cooperation, and can cooperate with the corresponding timing positioning tool. The third direction is the movement direction of the corresponding timing positioning tool extending into the first camshaft mounting hole 16, or the movement direction of the corresponding timing positioning tool extending into the second camshaft mounting hole 17. It should be noted that the corresponding timing positioning tool has two opposite clamping surfaces, so the first timing positioning surface 211 and the second timing positioning surface 311 are arranged relative to each other, so that the first timing positioning surface 211 and the second timing positioning surface 311 can be better adapted to the two clamping surfaces of the corresponding timing positioning tool, so that the corresponding timing positioning tool can better cooperate with the first camshaft 20 or the second camshaft 30.

[0058] Specifically, since the timing positioning tool can only be inserted along the third direction, it is necessary to rotate the first camshaft 20 or the second camshaft 30 to cooperate with the corresponding timing positioning tool. When the first timing positioning surface 211 and the second timing positioning surface 311 on the first camshaft 20 or the second camshaft 30 are parallel to the third direction, the clamping surface of the corresponding timing positioning tool can be just clamped on the first timing positioning surface 211 and the second timing positioning surface 311, so that the positioning cooperation between the corresponding timing positioning tool and the first camshaft 20 or the second camshaft 30 can be achieved.

[0059] In addition, if Figure 6As shown, the cylinder head cover 1 also includes an oil-gas separation device 40, and the intake side 11 is also provided with an oil-gas separation device 40 mounting portion, the first timing positioning mounting portion 12 is located at the oil-gas separation device 40 mounting portion, and the oil-gas separation device 40 is installed at the oil-gas separation device 40 mounting portion. Among them, the oil-gas separation device 40 mainly plays the role of separating oil and liquid from gas. The oil-gas separation device 40 mounting portion mainly plays the role of installation, and the oil-gas separation device 40 can be installed to make the setting of the oil-gas separation device 40 more reliable and stable. The oil-gas separation device 40 mounting portion is set on the intake side 11, so that the oil-gas separation device 40 can separate the oil and liquid in the gas entering the engine 2, and prevent the oil and liquid from entering the engine 2 from the intake port, so that the engine 2 can work better.

[0060] The first timing positioning installation part 12 is located at the installation part of the oil-gas separation device 40, that is, the first timing positioning installation part 12 and the installation part of the oil-gas separation device 40 share a common installation position. During the assembly process, the corresponding timing positioning tool will first be installed on the first timing positioning installation part 12. After the timing system of the engine 2 is installed, the timing positioning tool will be removed from the first timing positioning installation part 12, and then the oil-gas separation device 40 will be installed at the oil-gas separation installation part. This can simplify the processing steps and reduce costs.

[0061] In addition, if Figure 6 As shown, the cylinder head cover 1 also includes a camshaft cover plate 50, which is installed on the second timing positioning installation portion 14. The camshaft cover plate 50 mainly plays a role of sealing. The camshaft cover plate 50 is installed on the second timing positioning installation portion 14, so that the camshaft cover plate 50 can be used to seal the second timing positioning installation portion 14, so that the second timing positioning port 19 can be further sealed to prevent the external environment from interfering with the operation of the second camshaft 30, so that the engine 2 can work better.

[0062] The engine 2 according to the embodiment of the utility model comprises a cylinder head 201 and a cylinder head cover 1 of the above-mentioned embodiment, wherein the cylinder head cover 1 is disposed on the cylinder head 201. The cylinder head 201 mainly serves as a cover, and the cylinder head cover 1 is disposed on the cylinder head 201, so that the cylinder head cover 1 can be used to cover the cylinder head 201, thereby preventing the external environment from interfering with the corresponding components on the cylinder head 201, and thus enabling the engine 2 to work better.

[0063] Specifically, when assembling the engine 2, first assemble the first camshaft 20 and the second camshaft 30 into the corresponding first camshaft mounting hole 16 and the second camshaft mounting hole 17, and then assemble the cylinder head cover 1 onto the cylinder head 201. Rotate the first camshaft 20 and the second camshaft 30 so that the first timing positioning surface 211 and the second timing positioning surface 311 on the first camshaft 20 and the second camshaft 30 are parallel to the third direction, and then use the corresponding timing positioning tool to respectively cooperate with the first timing positioning surface 211 and the second timing positioning surface 311 on the first camshaft 20 and the second camshaft 30. Assemble the timing system of the engine 2. After the timing system of the engine 2 is assembled, remove the corresponding timing positioning tool, and install the oil-gas separation device 40 and the camshaft cover plate 50.
