Description

Technical Field

[0001] This application relates to the field of single-cylinder engines, and in particular to single-cylinder low-emission and energy-saving cylinder heads. Background Technology

[0002] In a single-cylinder engine, the cylinder head is one of the key components. Its main function is to seal the top of the cylinder and, together with the cylinder wall and the piston top, form the combustion chamber. The single-cylinder low-emission energy-saving cylinder head is an engine component designed specifically to reduce energy consumption and exhaust emissions. It improves fuel economy and combustion efficiency by optimizing the combustion chamber structure and improving the intake and exhaust port design.

[0003] A traditional cylinder head typically consists of a cylinder head body and a top cover, which are bolted to the cylinder. The cylinder head has intake ports, exhaust ports, and fuel injection ports to enable the engine's intake, exhaust, and fuel injection functions.

[0004] However, in the installation of existing single-cylinder cylinder heads, the cylinder head body and the top cover need to be precisely aligned during installation so that the fixing bolts can pass smoothly through the corresponding fixing holes. However, in actual operation, due to the high alignment accuracy requirements of the cylinder head body and the top cover, alignment difficulties are prone to occur during installation, resulting in low installation efficiency. Utility Model Content

[0005] The purpose of this application is to address the problem mentioned in the background art that the cylinder head body and the top cover have high alignment accuracy requirements, which makes alignment difficulties easy to occur during installation, resulting in low installation efficiency. This application provides a single-cylinder low-emission energy-saving cylinder head.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A single-cylinder low-emission energy-saving cylinder head includes a cylinder head body, a top cover on the cylinder head body, an air inlet on the cylinder, an air outlet on the cylinder, an oil injection hole on the cylinder, corresponding fixing holes on both the cylinder head and the top cover, and an alignment mechanism between the cylinder head body and the top cover.

[0008] By adopting the above technical solution, special fixing bolts are used to pass through the fixing holes on the cylinder head body and the upper cover to complete the fixing of the cylinder head body and the upper cover. During the fixing process, the upper cover is placed on the cylinder head body, and the upper cover is aligned with the cylinder head body using an alignment mechanism. Then, the cylinder head body and the upper cover are temporarily fixed, which makes it easy to align the cylinder head body and the upper cover and to pass the fixing bolts through the fixing holes.

[0009] Furthermore, the alignment mechanism includes two symmetrical alignment blocks 1 fixed on the upper cover, and two symmetrical alignment blocks 2 fixed on the cylinder head body. The alignment blocks 1 and 2 correspond to each other. An alignment rod is fixed on the alignment block 1, and an alignment hole corresponding to the alignment rod is opened on the alignment block 2. A locking component is provided between the alignment blocks 1 and 2, and a pulling component is provided on the alignment block 2.

[0010] By adopting the above technical solution, when the top cover is close to the cylinder head body, the alignment rod on the first alignment block is inserted into the alignment hole on the second alignment block, and then the locking component is used to temporarily fix the first alignment block and the second alignment block, so that the top cover can be aligned with the cylinder head body and the cylinder head body can be temporarily fixed to the top cover, which is convenient for fixing with fixing bolts.

[0011] Furthermore, the locking assembly includes a locking rod fixed on the first alignment block, and the second alignment block has a locking hole corresponding to the locking rod. A locking block is provided in the locking hole, and both the locking block and the locking rod have locking teeth that face opposite directions.

[0012] By adopting the above technical solution, the locking rod fixed on the first alignment block is inserted into the locking hole on the second alignment block, and then the locking block is used to temporarily fix the locking rod, so that the cylinder head body and the upper cover can be temporarily fixed together.

[0013] Furthermore, a support block is fixed to one side of the second alignment block, the locking block is slidably connected to the support block, and the locking block passes through the second alignment block.

[0014] By adopting the above technical solution, the locking block is supported by the support block, allowing the locking block to slide on the support block, thereby facilitating the movement of the locking block.

[0015] Furthermore, an abutment spring is provided between the locking block and the support block, and both ends of the abutment spring are fixedly connected to the locking block and the support block.

[0016] By adopting the above technical solution, the locking block is supported by the anti-collision spring, which makes it easy for the locking rod to move unidirectionally on the locking block and for the locking block to be locked on the locking rod.

[0017] Furthermore, the end of the alignment rod furthest from the alignment block is tapered.

[0018] By adopting the above technical solution, when the alignment rod is inserted into the alignment hole on the second alignment block, the conical inclined surface on the alignment rod abuts against the edge of the alignment hole. Guided by the inclined surface of the conical head, the alignment rod is inserted into the alignment hole of the second alignment block, thus making it easy to insert the alignment rod into the alignment hole.

[0019] Furthermore, a pull rod is fixed on the locking block, the pull rod passes through the support block and is slidably connected to the support block, and a pull block is fixed to the end of the pull rod away from the locking block.

[0020] By adopting the above technical solution, the locking block is driven by the pulling rod, which separates the locking block from the locking rod, thereby making it easy to pull the locking rod out of the alignment block two.

[0021] Furthermore, a limiting threaded rod is threadedly connected to the pull block, the limiting threaded rod passes through the pull block, and a limiting hole corresponding to the limiting threaded rod is provided on the cylinder head body.

[0022] By adopting the above technical solution, the limiting threaded rod moves on the pulling block and is inserted into the limiting hole, thereby making it easy to keep the locking block separated from the locking rod.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, when the top cover is fixed to the cylinder head body, the top cover is close to the cylinder head body, and the first alignment block on the top cover is close to the second alignment block on the cylinder head body. The alignment rod on the first alignment block is inserted into the alignment block. Under the constraint of the alignment rod, the cylinder head body and the top cover are aligned. Then, the cylinder head body and the top cover abut together. When the first alignment block and the second alignment block are close to each other, the locking rod on the first alignment block is inserted into the locking hole on the second alignment block. The inclined surface of the locking tooth on the locking rod abuts against the inclined surface of the locking tooth on the locking block. Then, the locking rod slides between the locking rod and the locking block. After the cylinder head body and the top cover are completely abut together, the locking block is locked on the locking rod under the push of the abutment spring, thus completing the temporary fixation of the cylinder head body and the top cover. Then, the fixing bolt is passed through the fixing holes of the cylinder head body and the top cover to complete the fixed connection of the cylinder head body and the top cover. This achieves the purpose of facilitating the alignment of the top cover and the cylinder head body, temporarily fixing the cylinder head body and the top cover, and facilitating the fixing with fixing bolts.

[0025] 2. In this application, when it is necessary to remove the top cover from the cylinder head body, the pulling block directly drives the pulling rod, which in turn drives the locking block. The locking block slides on the support block, separating the locking block from the locking teeth on the locking rod. Then, the limiting threaded rod is rotated, allowing it to move on the pulling block and insert into the limiting hole, keeping the locking block separated from the locking rod. This achieves the purpose of easily retracting the locking block into the support block and easily pulling the locking rod out from the second alignment block. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1 —3 provides further detailed description of this application.

[0032] This application discloses a single-cylinder low-emission energy-saving cylinder head.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A single-cylinder low-emission energy-saving cylinder head includes a cylinder head body 1, an upper cover 2 on the cylinder head body 1, an air inlet 3 on the cylinder, an air outlet 4 on the cylinder, an oil injection hole 7 on the cylinder, corresponding fixing holes 5 on both the cylinder head and the upper cover 2, and an alignment mechanism 6 between the cylinder head body 1 and the upper cover 2.

[0034] When using the cylinder head body 1, the cylinder head body 1 is fixed to the cylinder, and then the upper cover 2 is fixed to the cylinder head body 1. When fixing the upper cover 2 to the cylinder head body 1, special fixing bolts are used to pass through the fixing holes 5 on the cylinder head body 1 and the upper cover 2 to complete the fixing of the cylinder head body 1 and the upper cover 2. During the fixing process, the upper cover 2 is placed on the cylinder head body 1. When the upper cover 2 is brought close to the cylinder head body 1, the alignment mechanism 6 is used to align the upper cover 2 and the cylinder head body 1. Then the cylinder head body 1 and the upper cover 2 are temporarily fixed. Then the fixing bolts are used to pass through the fixing holes 5 on the cylinder head body 1 and the upper cover 2 to complete the fixing of the cylinder head body 1 and the upper cover 2. By using the alignment mechanism 6 to align the upper cover 2 and the cylinder head body 1 when fixing the upper cover 2 to the cylinder head body 1 and temporarily fixing it, it is convenient to align the cylinder head body 1 and the upper cover 2 and to pass the fixing bolts through the fixing holes 5.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The alignment mechanism 6 includes two symmetrical alignment blocks 61 fixed on the upper cover 2, and two symmetrical alignment blocks 62 fixed on the cylinder head body 1. Alignment blocks 61 and alignment blocks 62 correspond to each other. Alignment rods 63 are fixed on alignment blocks 61. Alignment holes corresponding to alignment rods 63 are opened on alignment blocks 62. Locking components 64 are provided between alignment blocks 61 and alignment blocks 62. Pulling components 65 are provided on alignment blocks 62.

[0036] In addition, the locking assembly 64 includes a locking rod 641 fixed on the first alignment block 61, and a locking hole corresponding to the locking rod 641 is provided on the second alignment block 62. A locking block 642 is provided in the locking hole. Both the locking block 642 and the locking rod 641 are provided with locking teeth, which are oriented in opposite directions.

[0037] Furthermore, a support block 643 is fixed on one side of the alignment block 2 62, and the locking block 642 is slidably connected to the support block 643, with the locking block 642 penetrating through the alignment block 2 62.

[0038] Furthermore, a retaining spring 644 is provided between the locking block 642 and the support block 643, and both ends of the retaining spring 644 are fixedly connected to the locking block 642 and the support block 643.

[0039] Furthermore, the end of the alignment rod 63 furthest from the alignment block 61 is tapered.

[0040] When the upper cover 2 is fixed to the cylinder head body 1, the upper cover 2 is close to the cylinder head body 1, and the first alignment block 61 on the upper cover 2 is close to the second alignment block 62 on the cylinder head body 1. The alignment rod 63 on the first alignment block 61 is inserted into the alignment block. Under the constraint of the alignment rod 63, the cylinder head body 1 is aligned with the upper cover 2, and then the cylinder head body 1 and the upper cover 2 abut together. When the first alignment block 61 and the second alignment block 62 approach each other, the locking rod 641 on the first alignment block 61 is inserted into the locking hole on the second alignment block 62. The inclined surface of the locking tooth on the locking rod 641 abuts against the inclined surface of the locking tooth on the locking block 642, and then the locking rod 641 slides between the locking block 642 and the locking block 642. After the cylinder head body 1 and the upper cover 2 are fully abutted together, the locking block 642 is locked onto the locking rod 641 under the push of the abutment spring 644, thus temporarily fixing the cylinder head body 1 and the upper cover 2. Then, the fixing bolts are passed through the fixing holes 5 of the cylinder head body 1 and the upper cover 2 to complete the fixed connection between the cylinder head body 1 and the upper cover 2. The alignment rod 63 on the first alignment block 61 is inserted into the alignment groove on the second alignment block 62, and then the locking rod 641 and the locking block 642 are used for temporary fixing. This makes it easy to align the upper cover 2 with the cylinder head body 1 and temporarily fix the cylinder head body 1 and the upper cover 2, which is convenient to fix with the fixing bolts.

[0041] Reference Figure 2 and Figure 3 A pull rod 651 is fixed on the locking block 642. The pull rod 651 passes through the support block 643 and is slidably connected to the support block 643. A pull block 652 is fixed to the end of the pull rod 651 away from the locking block 642.

[0042] In addition, a limiting threaded rod 653 is threadedly connected to the pull block 652, the limiting threaded rod 653 passes through the pull block 652, and a limiting hole 654 corresponding to the limiting threaded rod 653 is opened on the cylinder head body 1.

[0043] When it is necessary to remove the upper cover 2 from the cylinder head body 1, the pulling block 652 directly drives the pulling rod 651, which in turn drives the locking block 642. The locking block 642 slides on the support block 643, separating the locking block 642 from the locking teeth on the locking rod 641. Then, the limiting threaded rod 653 is rotated, moving on the pulling block 652 and inserting into the limiting hole 654. This keeps the locking block 642 separated from the locking rod 641. By using the pulling rod 651 to move the locking block 642 and then inserting the limiting threaded rod 653 into the limiting hole 654, the pulling block 652 keeps the locking block 642 stationary. This allows the locking block 642 to be easily retracted into the support block 643, and the locking rod 641 to be easily pulled out from the alignment block 62.

[0044] Working principle: When using the cylinder head body 1, the cylinder head body 1 is fixed to the cylinder, and then the upper cover 2 is fixed to the cylinder head body 1. When the upper cover 2 is fixed to the cylinder head body 1, the upper cover 2 is close to the cylinder head body 1, and the alignment block 1 61 on the upper cover 2 is close to the alignment block 2 62 on the cylinder head body 1. The alignment rod 63 on the alignment block 1 61 is inserted into the alignment block. Under the restriction of the alignment rod 63, the cylinder head body 1 and the upper cover 2 are aligned. Then the cylinder head body 1 and the upper cover 2 abut together. When the alignment block 1 61 and the alignment block 2 62 approach each other, the locking rod 641 on the alignment block 1 61 is inserted into the locking hole on the alignment block 2 62. The inclined surface of the locking tooth on the locking rod 641 abuts against the inclined surface of the locking tooth on the locking block 642. Then the locking rod 641 slides between the locking block 642 and the locking block 642. After the main body 1 and the upper cover 2 are completely in contact, the locking block 642 is locked onto the locking rod 641 under the push of the contact spring 644, thus temporarily fixing the cylinder head main body 1 and the upper cover 2. Then, the fixing bolts are passed through the fixing holes 5 of the cylinder head main body 1 and the upper cover 2 to complete the fixed connection between the cylinder head main body 1 and the upper cover 2. When it is necessary to remove the upper cover 2 from the cylinder head main body 1, the pulling block 652 drives the pulling rod 651, which in turn drives the locking block 642. The locking block 642 slides on the support block 643, separating the locking block 642 from the locking teeth on the locking rod 641. Then, the limiting threaded rod 653 is rotated, moving on the pulling block 652 and inserting into the limiting hole 654, keeping the locking block 642 separated from the locking rod 641.
