Description

Technical Field

[0001] The invention relates to the technical field of cylinder heads, and in particular to an improved cylinder head structure. Background Art

[0002] The motorcycle cylinder head, also known as the cylinder head, is one of the important components of the engine and is usually located at the top of the engine cylinder. It closes the cylinder and forms a combustion chamber together with the piston and cylinder wall, where the fuel mixture burns. The cylinder head contains the intake and exhaust ducts and valve mechanisms to ensure that the air-fuel mixture is introduced into the combustion chamber at the right time and the exhaust gas is discharged after combustion.

[0003] Existing motorcycle cylinder heads often face the problem of insufficient heat dissipation during design and actual use. This limitation of heat dissipation performance results in the cylinder head being unable to effectively dissipate the high temperature generated by the combustion process during operation, making its operating temperature relatively high. Being in such a high temperature environment for a long time will not only accelerate the aging of the material, but may also cause problems such as metal fatigue and seal failure, which directly affect the mechanical stability and reliability of the cylinder head and even the entire engine. Summary of the invention

[0004] The object of the present invention is to provide an improved cylinder head structure, aiming to achieve an efficient heat dissipation function, so that the cylinder head can work in a better temperature environment to increase the life of the cylinder head.

The two valves work together to ensure the normal breathing of the engine. The ignition plug is arranged on one side of the cylinder head, and its function is to generate electric sparks at the right time to ignite the mixed gas and initiate combustion, thereby providing power for the engine. In addition to the above common components, the cylinder head structure also introduces mounting parts, piston barrels, cooling components and sealing sleeves. The piston barrel is cleverly arranged below the cylinder head. The mounting parts pass through the piston barrel and the cylinder head, tightly connecting the various components together, ensuring the stability and reliability of the entire structure.

[0026] See also Figures 1 to 8The present invention provides an improved cylinder head structure, including a cylinder head 101, an intake valve 102, an outlet valve 103 and an ignition plug 104, wherein the intake valve 102 and the outlet valve 103 are arranged on the cylinder head 101, and the ignition plug 104 is arranged on one side of the cylinder head 101. The present invention also includes a mounting member 105, a piston cylinder 106 and a cooling assembly 107, wherein the piston cylinder 106 is arranged below the cylinder head 101, and the mounting member 105 passes through the piston cylinder 106 and the cylinder head 101, and the piston cylinder 106 includes a cylinder body 130 and a plurality of ribs 131, wherein the cylinder body 130 has a cooling groove 109, and the cooling assembly 107 is provided at the cooling groove 109. Cooling liquid is arranged in the groove 109, and a plurality of ribs 131 are fixed in the cooling groove 109. The cooling assembly 107 includes a plurality of first U-shaped tubes, a plurality of second U-shaped tubes, a liquid inlet pipe 112 and a liquid outlet pipe 113. The first U-shaped tubes are respectively arranged between two of the ribs 131, the second U-shaped tube is arranged in the cylinder head 101 and is connected with two adjacent first U-shaped tubes. The liquid inlet pipe 112 and the liquid outlet pipe 113 are arranged on the cylinder head 101, so that the circulating liquid enters the first U-shaped tube through the second U-shaped tube and then alternately passes through the first U-shaped tube and the second U-shaped tube and is finally discharged through the liquid outlet pipe 113.

[0027] In this embodiment, the intake valve 102 and the outlet valve 103 are precisely arranged on the cylinder head 101. The intake valve 102 is responsible for inhaling fresh mixed gas, while the outlet valve 103 is used to discharge the exhaust gas after combustion. The two work together to ensure the normal breathing of the engine. The ignition plug 104 is arranged on one side of the cylinder head 101. Its function is to generate electric sparks at the right time to ignite the mixed gas and initiate combustion, thereby providing power for the engine.

[0028] In addition to the common components mentioned above, the cylinder head structure also introduces a mounting member 105, a piston cylinder 106, a cooling assembly 107 and a sealing sleeve 118. The piston cylinder 106 is cleverly arranged below the cylinder head 101. The mounting member 105 passes through the piston cylinder 106 and the cylinder head 101, tightly connecting the various components together, ensuring the stability and reliability of the entire structure.

[0029] The piston cylinder 106 is composed of a cylinder body 130 and a plurality of ribs 131. A cooling groove 109 is designed on the cylinder body 130. The cooling groove 109 is filled with a coolant. The coolant can effectively absorb a large amount of heat generated during the operation of the engine, prevent the piston cylinder 106 from being damaged due to overheating, and ensure the stable operation of the engine. The plurality of ribs 131 are firmly fixed in the cooling groove 109, which enhances the structural strength of the piston cylinder 106.

[0030] The cooling assembly 107 is the heat dissipation core of the entire cylinder head structure, including a plurality of first U-shaped tubes, a plurality of second U-shaped tubes, a liquid inlet pipe 112 and a liquid outlet pipe 113. The first U-shaped tubes are respectively arranged between two ribs 131, and the second U-shaped tube is arranged in the cylinder head 101, and is interconnected with two adjacent first U-shaped tubes. The liquid inlet pipe 112 and the liquid outlet pipe 113 are arranged on the cylinder head 101. When the engine is running, the circulating fluid enters the second U-shaped tube through the liquid inlet pipe 112, and then smoothly enters the first U-shaped tube, and then alternately passes through the first U-shaped tube and the second U-shaped tube, fully absorbing the heat generated by the engine, and finally discharges the heat through the liquid outlet pipe 113, and so on, and the cycle is repeated, realizing an efficient heat dissipation function. The sealing sleeve 118 plays a good sealing role, preventing the leakage of coolant and other gases or liquids, and ensuring the normal operation of the entire system.

[0031] The mounting member 105 includes a bolt 114 , a nut 115 and a washer 116 . The bolt 114 passes through the cylinder 130 and the cylinder head 101 . The nut 115 is threadedly connected to the bolt 114 . The washer 116 is disposed between the nut 115 and the cylinder 130 .

[0032] As the core component of the mounting member 105, the bolt 114 is designed to pass through the cylinder 130 of the piston cylinder 106 and the key part of the cylinder head 101. This design ensures that the piston cylinder 106 and the cylinder head 101 can still maintain a tight connection even under the strong vibration and pressure generated during the operation of the engine.

[0033] The bolt 114 is matched with a nut 115, which is threaded to tighten the bolt 114. The selection of the nut 115 also takes into account durability and vibration resistance, ensuring that it does not loosen under long-term working conditions and maintains the stability and safety of the entire system.

[0034] The washer 116 effectively disperses the pressure applied by the nut 115 , thereby preventing the surface of the cylinder 130 from being damaged or deformed due to excessive local pressure.

[0035] A chamfer 117 is formed at a connection between the rib 131 and the cylinder 130 .

[0036] The chamfer 117 design makes the rib 131 and the cylinder 130 smoother when connected, reduces stress concentration points, and reduces the risk of fracture under high load conditions. At the same time, the chamfer 117 also helps to improve the processing efficiency during the manufacturing process, facilitates accurate assembly operations, and reduces possible errors.

[0037] In addition, by providing the chamfer 117 at the connection, not only can the force distribution be optimized, the connection between the rib 131 and the cylinder 130 be more firmly established, but also the structural strength of the entire piston cylinder 106 can be effectively enhanced. This prolongs the service life of the components to a certain extent and improves the reliability and durability of the entire engine.

[0038] The cooling assembly 107 further includes a sealing sleeve 118 , and the sealing sleeve 118 is disposed between the first U-shaped tube and the second U-shaped tube.

[0039] The sealing sleeve 118 is designed to ensure effective circulation of the coolant in the entire cooling system while preventing any possible leakage, thereby ensuring stable operation of the entire system.

[0040] The sealing sleeve 118 includes a plurality of sleeves 119, a connecting ring 120 and a plurality of support rods 121. The connecting ring 120 is sleeved onto the inner side of the cylinder 130. The plurality of support rods 121 are fixedly connected to the connecting ring 120. The plurality of sleeves 119 are respectively fixedly connected to the plurality of support rods 121 and are located on one side of the support rods 121.

[0041] The sealing sleeve 118 is particularly arranged between the first U-shaped tube and the second U-shaped tube to ensure that the connection between the two parts is tight and leak-free. This design is crucial to maintaining the integrity and efficiency of the cooling system.

[0042] The sealing sleeve 118 includes a plurality of sleeves 119, which are respectively fixed on one side of the support rod 121. The cross-sectional area at both ends of each sleeve 119 is larger than the cross-sectional area in the middle. This unique shape design helps to enhance the sealing effect and provides a certain elastic space to adapt to the changes of thermal expansion and contraction under different working conditions.

[0043] The connecting ring 120 is one of the key components of the sealing sleeve 118, and is sleeved on the inner side of the cylinder 130. In this way, the connecting ring 120 can be firmly fixed on the inner wall of the cylinder 130, providing a solid foundation for other components. The design of the connecting ring 120 takes into account the characteristics of high temperature resistance and corrosion resistance, ensuring that it can still maintain good performance in harsh environments.

[0044] A plurality of support rods 121 are fixedly connected to the connecting ring 120, and each support rod 121 is connected to a corresponding sleeve 119. The support rods 121 not only play a role of physical connection, but also enhance the stability of the overall structure, ensuring that the sleeve 119 can work normally under high pressure and high temperature conditions.

[0045] The cross-sectional areas of the two sections of the sleeve 119 are larger than the cross-sectional area of ​​the middle section.

[0046] The design of the cross-sectional area of ​​the two ends of the sleeve 119 being larger than that of the middle part is not only for aesthetics, but more importantly, it improves the sealing performance. The larger ends can better fit the interface of the U-shaped tube, forming an effective sealing layer to prevent coolant leakage. At the same time, the thinner design of the middle part helps to reduce material usage and reduce manufacturing costs.

[0047] The cooling assembly 107 further includes a sealing ring 122 , and the sealing ring 122 is disposed between the cylinder head 101 and the cylinder body 130 .

[0048] The main function of the sealing ring 122 is to ensure that the connection between the two parts is tight and leak-free, and to prevent the coolant from leaking out from the interface.

[0049] The cooling assembly 107 also includes a cooling pipe 123, a collecting cavity 124 and a circulating pump 125. The cooling pipe 123 is connected to the liquid inlet pipe 112 and the liquid outlet pipe 113. The collecting cavity 124 is connected to the cooling pipe 123. The circulating pump 125 is connected to the collecting cavity 124 and the cooling pipe 123.

[0050] The cooling pipes 123 are connected with the liquid inlet pipe 112 and the liquid outlet pipe 113 to form a complete liquid flow path, so that the cooling liquid can be cooled from the outside.

[0051] The cooling assembly 107 further includes a collecting chamber 124, which is in communication with the cooling pipe 123. The collecting chamber 124 serves as a collection point for the coolant, where the coolant can be temporarily stored and redistributed to the cooling system through the circulation pump 125. This design helps to balance the flow of the coolant, ensuring that each part can obtain enough coolant for effective heat exchange.

[0052] The circulating pump 125 is the heart of the entire cooling system, and is connected to the collecting chamber 124 and the cooling pipe 123. The circulating pump 125 is responsible for promoting the circulation of the coolant in the entire cooling system. By accurately controlling the flow rate and flow direction of the coolant, the circulating pump 125 can effectively adjust the cooling effect and ensure that the engine can maintain a suitable operating temperature under various working conditions. In addition, the selection of the circulating pump 125 takes into account its energy efficiency ratio and durability, and can maintain an efficient and stable working state during long-term operation.

[0053] The improved cylinder head structure also includes a detection component 126, which includes a temperature detection unit 127, a judgment unit 128 and an alarm unit 129. The temperature detection unit 127 is used to detect the temperature data in the collection cavity 124, the judgment component is used to compare the temperature data with a preset value to obtain a difference, and the alarm unit 129 is used to issue an alarm based on the difference.

[0054] The temperature detection unit 127 is used to detect the temperature data in the collection chamber 124. It uses a high-precision temperature sensor that can accurately measure the real-time temperature of the coolant. These sensors are usually installed in key locations along the coolant flow path, such as in the collection chamber 124, to ensure the most accurate temperature readings. The design of the temperature detection unit 127 takes into account its sensitivity to environmental changes and its response speed, and can capture temperature changes in a very short time, providing reliable data support for subsequent processing.

[0055] The judgment unit 128 is the core logic processing center of the entire detection system. Its main responsibility is to compare the temperature data obtained by the temperature detection unit 127 with the preset safety threshold. Through this comparison, the judgment unit 128 can calculate the difference between the actual temperature and the safety threshold, and evaluate whether the current system operation state is within the safety range. If the difference exceeds the predetermined range, it indicates that the system may have overheating or other potential problems, which require further attention or measures.

[0056] The judgment unit 128 can also set multiple preset values ​​according to different application scenarios, such as a normal operating temperature range, a warning temperature threshold, and an emergency shutdown temperature threshold, etc. In this way, the alarm strategy can be flexibly adjusted according to actual conditions to improve the adaptability and safety of the system.

[0057] Once the judgment unit 128 finds that the temperature difference exceeds the safe range, the alarm unit 129 will be activated immediately and issue a corresponding alarm. The alarm method can be diversified, including but not limited to sound alarm, light signal warning and even remote notification (such as SMS or application push). This allows operators to be notified quickly no matter where they are, and take necessary countermeasures in time to avoid equipment damage or safety accidents caused by overheating.

[0058] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
