Description

Technical Field

[0001] This utility model relates to the field of engine cylinder block technology, specifically a motorcycle engine cylinder block. Background Technology

[0002] As a thermal machine, the piston chamber inside the engine cylinder inevitably generates a lot of heat during operation due to the high-speed reciprocating motion of the piston, as well as the combustion of oil in the cylinder, all of which can lead to excessively high cylinder temperatures.

[0003] Existing motorcycle engine cylinder blocks typically dissipate heat directly through externally installed cooling fins. However, relying solely on the cooling fins for heat dissipation will gradually cause the fins to heat up over long periods of operation, resulting in increasingly poor heat dissipation performance. Therefore, a new type of motorcycle engine cylinder block has been proposed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention provides a motorcycle engine cylinder block to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a motorcycle engine cylinder block, including a cylinder block body, the outer surface of which is provided with a plurality of heat dissipation fins, the outer surface of which is provided with cooling pipes, the plurality of cooling pipes forming a circulation path, one of which is fixedly connected to a pressure pipe on its outer surface, the outer surface of which is fixedly connected to a negative pressure cylinder, a negative pressure airbag is provided inside the negative pressure cylinder, a movable cylinder is movably inserted on the outer surface of the negative pressure cylinder, a disc is fixedly connected to one side of the movable cylinder inside the negative pressure cylinder, and an air duct is fixedly connected to the side of the movable cylinder away from the negative pressure cylinder.

[0006] Furthermore, an air guide plate is fixedly connected to the outer surface of the cylinder body, and an air guide shroud is fixedly connected to one side of the air guide plate.

[0007] Furthermore, a spring is fixedly connected between the negative pressure cylinder and the disc, and the spring is sleeved on the outer surface of the movable cylinder.

[0008] Furthermore, the external opening diameter of both the air hood and the air guide hood is larger than their internal diameter.

[0009] Furthermore, a one-way valve is installed inside the pressure-applying pipe, and the flow direction of the one-way valve is from the inside of the negative pressure cylinder to the inside of the cooling pipe.

[0010] Furthermore, the outer surface of the uppermost cooling pipe is fixedly connected to an inlet pipe, and the outer surface of the lowermost cooling pipe is fixedly connected to an outlet pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The engine cylinder block of this motorcycle uses cooling fins for heat dissipation during use. The airflow generated when the motorcycle is moving causes the moving cylinder to drive the disc to compress the negative pressure airbag. In conjunction with the spring, the coolant in the cooling pipe is kept in a flowing state, which increases the heat dissipation effect of the cooling fins.

[0013] 2. The engine cylinder block of this motorcycle allows airflow to enter the air guide plate through the air guide shroud when the motorcycle is running, and blow it towards the cooling pipe, where it exchanges heat with the coolant in the cooling pipe, keeping the coolant at a low temperature.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1:

[0020] Please refer to the following: Figures 1-3This utility model provides a technical solution: a motorcycle engine cylinder block, including a cylinder block body 1. Multiple cooling fins 2 are provided on the outer surface of the cylinder block body 1. Cooling pipes 3 are provided on the outer surface of each cooling fin 2, and the multiple cooling pipes 3 form a circulation path. A pressure pipe 4 is fixedly connected to the outer surface of one of the cooling pipes 3. A negative pressure cylinder 5 is fixedly connected to the outer surface of the pressure pipe 4. A negative pressure airbag 6 is provided inside the negative pressure cylinder 5. A movable cylinder 7 is movably inserted into the outer surface of the negative pressure cylinder 5. A disc 9 is fixedly connected to one side of the movable cylinder 7 inside the negative pressure cylinder 5, and an air duct 8 is fixedly connected to the side of the movable cylinder 7 away from the negative pressure cylinder 5. Specifically, when the cylinder block body 1 is working... Heat is generated and dissipated through the heat dissipation fins 2. The heat on the heat dissipation fins 2 is exchanged with the coolant in the cooling pipe 3. During the motorcycle's operation, the air intake shroud 8 causes the movable cylinder 7 to move into the negative pressure cylinder 5 under the action of the wind, which causes the spring 10 to deform. This causes the disc 9 to squeeze the negative pressure airbag 6, causing it to deform. The negative pressure airbag 6 generates pressure that applies pressure to the pressure pipe 4, thereby pushing the coolant to flow in the cooling pipe 3. As the wind force changes, the spring 10 returns to its original position, and the airbag returns to its original position. This causes the movable cylinder 7 to drive the disc 9 to squeeze the airbag, thereby continuously applying pressure to the pressure pipe 4 and keeping the coolant flowing in the cooling pipe 3, thus increasing the heat dissipation effect of the heat dissipation fins 2.

[0021] In this embodiment, a wind guide plate 11 is fixedly connected to the outer surface of the cylinder body 1, and a wind guide shroud 12 is fixedly connected to one side of the wind guide plate 11. Specifically, when the motorcycle is running, the wind enters the wind guide plate 11 from the wind guide shroud 12, and the wind blows from the wind guide plate 11 to the cooling pipe 3, so that the coolant in the cooling pipe 3 is kept at a low temperature as much as possible.

[0022] In this embodiment, a spring 10 is fixedly connected between the negative pressure cylinder 5 and the disc 9. The spring 10 is sleeved on the outer surface of the movable cylinder 7. Specifically, when the movable cylinder 7 moves, the spring 10 is compressed, and when the spring 10 returns to its original position, it drives the movable cylinder 7 to return to its original position.

[0023] In this embodiment, the external opening diameters of both the air intake hood 8 and the air guide hood 12 are larger than their internal diameters. Specifically, the above-mentioned technical solution is adopted to improve the effect of airflow entering the interior of the air intake hood 8 and the air guide hood 12.

[0024] In this embodiment, a one-way valve is installed inside the pressure pipe 4. The flow direction of the one-way valve is from the inside of the negative pressure cylinder 5 to the inside of the cooling pipe 3. Specifically, the one-way valve is set to prevent the coolant from flowing back.

[0025] In this embodiment, the outer surface of the uppermost cooling pipe 3 is fixedly connected to an inlet pipe, and the outer surface of the lowermost cooling pipe 3 is fixedly connected to an outlet pipe. Specifically, coolant is added into the cooling pipe 3 through the inlet pipe, and the coolant is discharged through the outlet pipe.

[0026] Working principle: When this utility model is in use, the cylinder body 1 generates heat during operation, which is dissipated through the heat dissipation fins 2. The heat on the heat dissipation fins 2 is exchanged with the coolant in the cooling pipe 3. During the motorcycle's operation, the air intake shroud 8 causes the movable cylinder 7 to move into the negative pressure cylinder 5 under the action of the wind, which causes the spring 10 to deform. This causes the disc 9 to squeeze the negative pressure airbag 6, causing it to deform. The negative pressure airbag 6 generates pressure, which applies pressure to the pressure pipe 4, thereby pushing the coolant to flow in the cooling pipe 3. As the wind force changes, the spring 10 returns to its original position, and the airbag returns to its original position. This causes the movable cylinder 7 to drive the disc 9 to squeeze the airbag, thereby continuously applying pressure to the pressure pipe 4, keeping the coolant flowing in the cooling pipe 3, and increasing the heat dissipation effect of the heat dissipation fins 2.

[0027] When the motorcycle is in motion, the wind enters the air guide plate 11 from the air guide shroud 12, and the wind blows from the air guide plate 11 to the cooling pipe 3, so that the coolant in the cooling pipe 3 is kept at a low temperature as much as possible.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
