Description

Technical Field

[0001] This utility model belongs to the field of motorcycles and relates to motorcycle engine technology, specifically an energy-saving motorcycle engine. Background Technology

[0002] Electronic fuel injection motorcycles are motorcycles that use electronic fuel injection systems. The working principle of an electronic fuel injection motorcycle engine is to inject fuel into the cylinder through electronically controlled fuel injectors to achieve the engine combustion process.

[0003] The reference patent is titled: "An electronic fuel injection engine for an electronic fuel injection motorcycle (Patent Publication No.: CN216198424U)". By using a combination of a water tank, cooling pipes, heat dissipation fins and a water pump, the temperature of the electronic fuel injection engine body during operation is alleviated to a certain extent. This helps to ensure the temperature and working condition of the engine itself and its surrounding components, and prevents the electronic fuel injection engine body from stopping working due to excessive temperature.

[0004] However, the following problems exist when implementing the above technical solutions: the above devices use water pumps to circulate water and then cool the engine body through heat transfer. However, the water circulation speed in the above devices is mainly controlled by the water pump. During the cooling process, the speed of water circulation is limited and it is difficult to quickly adjust the water circulation speed in some situations. In addition, the water pump needs to be maintained and repaired regularly during the use of the whole device, which increases the maintenance cost of motorcycle use.

[0005] Therefore, this utility model proposes an energy-saving motorcycle engine. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an energy-saving motorcycle engine that addresses the issue that existing motorcycle engines primarily rely on water pumps to drive the circulation of cooling liquid to reduce engine operating temperature. However, using water pumps requires regular maintenance, leading to increased energy consumption and operating costs.

[0007] To achieve the above objectives, an energy-saving motorcycle engine is proposed according to an embodiment of the first aspect of this utility model, comprising an engine body and a cooling pipe, wherein a circulation mechanism is provided between the engine body and the cooling pipe, the circulation mechanism comprising:

[0008] A water tank is fixedly connected to one side of the engine body. A temperature conducting box is fixedly connected to the surface of the water tank and the engine body. A heat insulation block is slidably connected inside the temperature conducting box, and there is a gap between the surface of the heat insulation block and the temperature conducting box. A drive rod is slidably connected inside the temperature conducting box. A drive shaft is fixedly connected to the side of the heat insulation block away from the engine body. One end of the drive rod and the drive shaft is rotatably connected to a connecting shaft.

[0009] A drive rod is fixedly connected to a connecting shaft. The line connecting the contact position of the drive rod and the connecting shaft with the center of the drive rod and the line connecting the contact position of the driving shaft and the connecting shaft with the center of the drive rod form a 90-degree angle.

[0010] A drive block is slidably connected to the drive rod on the side away from the temperature conduction box. The surface of the drive block is in contact with the inner wall of the water tank. Two one-way valves are fixedly connected inside the water tank.

[0011] Optionally, there is a gap between the two one-way valves and the drive block, and the two one-way valves are respectively fixedly connected to both ends of the cooling pipe.

[0012] Optionally, an equipment box is fixedly connected to the side of the engine body away from the water tank, and a cooling groove is formed on the surface of the cooling pipe, the cooling groove being adapted to the cooling pipe.

[0013] Optionally, a limiting post is slidably connected inside the equipment box, a limiting rod is slidably connected inside the limiting post, and a limiting spring is fixedly connected between the limiting rod and the limiting post.

[0014] Optionally, an operating ring is slidably connected to the surface of the limiting rod, and a restoring spring is fixedly connected between the limiting rod and the operating ring.

[0015] Optionally, an operating column is fixedly connected to the surface of the operating ring, and a plurality of arc-shaped grooves are formed on the surface of the equipment box, the arc-shaped grooves being adapted to the operating column.

[0016] Optionally, a storage box is fixedly connected to the surface of the water tank, and a flow channel is provided on the side of the storage box away from the water tank. One side of the storage box is fixedly connected to the surface of the temperature conduction box.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: A temperature conducting box made of materials with different thermal conductivity is set on the surface of the engine body. The temperature conducting box and the heat insulation block are set. After the engine body heats up, the heat insulation block inside the temperature conducting box will move, which will drive the shaft and the drive rod to move back and forth. This will cause the connecting shaft to rotate asynchronously, which will cause the drive rod to rotate. The rotation of the drive rod will cause the drive block to move back and forth, which will drive the liquid and air inside the water tank to move continuously. Under the action of the one-way valve, the liquid inside the cooling pipe will continue to circulate, realizing water circulation and cooling the engine body. When the temperature difference between the engine body and the external environment is greater, the drive block will slide back and forth faster, which will accelerate the circulation of liquid inside the cooling pipe.

[0030] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] like Figure 1-5 As shown, an energy-saving motorcycle engine includes an engine body 1 and a cooling pipe 2.

[0032] The engine body 1 is an engine used in electronically fuel-injected motorcycles, and it has related structures inside (not shown in the figure);

[0033] A circulation mechanism is provided between the engine body 1 and the cooling pipe 2, the circulation mechanism comprising:

[0034] Water tank 31 is fixedly connected to one side of engine body 1. The side of water tank 31 in contact with engine body 1 is made of a material with low thermal conductivity. A temperature conduction box 32 is fixedly connected to the surface of water tank 31. One side of temperature conduction box 32 is in contact with engine body 1. The side of temperature conduction box 32 in contact with engine body 1 is made of a material with high thermal conductivity, while the side of temperature conduction box 32 away from engine body is made of a material with low thermal conductivity. As a result, there is a temperature difference between the two sides of temperature conduction box 32.

[0035] The temperature conduction chamber 32 is filled with gas, including but not limited to air, hydrogen and nitrogen; a temperature insulation block 33 is slidably connected inside the temperature conduction chamber 32, and the surface of the temperature insulation block 33 does not contact the inner wall of the temperature conduction chamber 32; thus, the gas inside the temperature conduction chamber 32 can flow through both sides of the temperature insulation block 33, so that the gas temperature difference on both sides of the temperature insulation block 33 is small.

[0036] The temperature conduction box 32 is slidably connected to a drive rod 34, and the side of the heat insulation block 33 away from the engine body 1 is fixedly connected to a drive shaft 35. One end of the drive rod 34 and the drive shaft 35 is rotatably connected to a connecting shaft 36.

[0037] The drive rod 37 is rotatably connected to the inside of the water tank 31 and fixedly connected to the connecting shaft 36. The line connecting the contact position of the drive rod 34 and the connecting shaft 36 with the center of the drive rod 37 and the line connecting the contact position of the drive shaft 35 and the connecting shaft 36 with the center of the drive rod 37 form a 90-degree angle. Therefore, when the drive rod 37 and the drive shaft slide and cause the connecting shaft 36 to rotate, the two connecting shafts 36 are not synchronized.

[0038] A drive block 38 is slidably connected to the drive rod 37 on the side away from the temperature conduction box 32. The surface of the drive block 38 is in contact with the inner wall of the water tank 31. Two one-way valves 39 are fixedly connected inside the water tank 31. There is a gap between the two one-way valves 39 and the drive block 38. The two one-way valves 39 are fixedly connected to both ends of the cooling pipe 2 respectively. The two one-way valves 39 control the liquid flow direction in different directions. The side of the drive block 38 inside the water tank 31 near the cooling pipe 2 is filled with water, and the other side is filled with air. A sealing ring is provided between the drive block 38 and the inner wall of the water tank 31. Therefore, during the sliding process of the drive block 38, the drive block 38 will squeeze the water inside the water tank 31 to move into the cooling pipe 2 or flow from the cooling pipe 2 into the water tank 31. Since the one-way valves 39 are provided between the cooling pipe 2 and the water tank 31, the movement of the drive block 38 will drive the liquid to flow in a single direction, realizing the circulation of the liquid inside the cooling pipe 2.

[0039] In practical application, this energy-saving motorcycle engine has a temperature-conducting box 32 made of materials with different thermal conductivity on the surface of the engine body 1. The temperature-conducting box 32 and the heat insulation block 33 are set up. When the engine body 1 heats up, the heat insulation block 33 inside the temperature-conducting box 32 will move, which will drive the shaft 35 and the drive rod 34 to move back and forth, causing the connecting shaft 36 to rotate asynchronously, causing the drive rod 37 to rotate. The rotation of the drive rod 37 causes the drive block 38 to move back and forth, which in turn causes the liquid and air inside the water tank 31 to move continuously. Under the action of the one-way valve 39, the liquid inside the cooling pipe 2 will continue to circulate, realizing water circulation and cooling the engine body 1. When the temperature difference between the engine body 1 and the external environment is greater, the drive block 38 will slide back and forth faster, which will accelerate the circulation of liquid inside the cooling pipe 2. Moreover, its cooling can be driven without a separate power supply, etc., which results in lower operating costs.

[0040] In some specific implementations, an equipment box 41 is fixedly connected to the side of the engine body 1 away from the water tank 31, and a cooling groove 42 is formed on the surface of the cooling pipe 2. The cooling groove 42 is adapted to the cooling pipe 2. The cooling grooves 42 on both sides of the equipment box 41 are rectangular, so the position of the cooling pipe 2 at both ends of the equipment box 41 can be changed according to the structure of the water tank 31 or related equipment to ensure the position of the cooling pipe 2 inside the equipment box 41.

[0041] In a further embodiment, a limiting post 51 is slidably connected inside the equipment box 41, a limiting rod 52 is slidably connected inside the limiting post 51, a limiting spring 53 is fixedly connected between the limiting rod 52 and the limiting post 51, an operating ring 54 is slidably connected to the surface of the limiting rod 52, a restoring spring 55 is fixedly connected between the limiting rod 52 and the operating ring 54, an operating post 56 is fixedly connected to the surface of the operating ring 54, and several arc-shaped grooves 57 are formed on the surface of the equipment box 41. The arc-shaped grooves 57 are adapted to the operating post 56, and the cooling tank 42 communicates with the arc-shaped grooves 57. The limiting post 51 further restricts the position of the cooling pipe 2, thereby ensuring that the position of the cooling pipe 2 will not change during use after it is determined, and ensuring the flow of liquid inside the cooling pipe 2.

[0042] In some specific implementations, a storage box 61 is fixedly connected to the surface of the water tank 31. A flow groove 62 is provided on the side of the storage box 61 away from the water tank 31. One side of the storage box 61 is fixedly connected to the surface of the temperature conduction box 32. A space is provided on the side of the temperature conduction box 32 away from the engine body 1 through the storage box 61, so that a certain amount of coolant can be placed on this side, increasing the temperature difference between the two sides of the temperature conduction box 32, causing the drive block 38 to slide more quickly, which can further improve the cooling rate of the engine body 1.

[0043] In some specific implementations, a sliding groove 72 is provided on the side of the drive block 38 near the drive rod 37. The cross-section of the drive rod 37 is L-shaped. A sliding shaft 71 is fixedly connected to the side of the drive rod 37 near the drive block 38. The sliding shaft 71 is adapted to the sliding groove 72.

[0044] The working principle of this utility model is as follows: After the generator body heats up, the temperature of the temperature conduction box 32 on the side close to the engine body 1 increases, and a temperature difference is generated inside the temperature conduction box 32. As a result, the heat insulation block 33 slides inside the temperature conduction box 32, causing the drive shaft 35 to slide. When the drive shaft 35 slides, some air moves towards the drive rod 34, causing the drive rod 34 to move. As a result, the connecting shaft 36 will rotate, causing the drive rod 37 to rotate. When the drive rod 37 rotates, the drive block 38 will slide inside the water tank 31, causing the liquid to flow inside the cooling pipe 2.

[0045] When adjusting the position of the cooling pipe 2, first slide the operating ring 54 to the outside of the equipment box 41 to disengage the operating column 56 from the arc groove 57. Then slide the limiting column 51. The sliding of the limiting column 51 changes the position of the cooling pipe 2. After the position of the cooling pipe 2 is determined, release the operating ring 54. The operating ring 54 will reset under the action of the return spring 55. The surface of the operating column 56 will fit with the arc groove 57, restricting the position of the limiting column 51 and fixing the position of the cooling pipe 2.

[0046] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
