The mounting part 2 is arranged in the intake box 101. The driver 3 is arranged on the mounting part 2, including a driving part 31 and a push rod 32 connected to the driving part 31, the driving part 31 can make the push rod 32 produce linear displacement. The sliding rail 4 is arranged on the mounting part 2 by a sliding rail support 41. The growth pipe 5 has a connecting part 50, which is slidably arranged on the sliding rail 4 and connected to the push rod 32. Among them, the push rod 32 is driven by the driving force of the driving part 31, so that the connecting part 50 can slide on the sliding rail 4, and then the growth pipe 5 can be selectively combined or separated with the intake pipe 102.

[0003] However, the driver 3 of the existing variable intake system 9 is often fixed on the mounting part 2 by using a driver locking accessory (not shown in the figure), when manufacturing problems or assembly defects occur, and in the environment of long-time engine vibration, the driver locking accessory may fall off into the intake box 101, thereby causing a high risk of safety problems to the motorcycle engine. The inventor has thus actively invented a variable intake system that can solve the above problems after years of research and experiments. UTILITY MODEL CONTENTS

[0004] The main purpose of the utility model is to provide a variable intake system, by making the growth pipe selectively combined or separated with the intake pipe, adjusting the overall length of the intake pipe, which can improve the power performance of high and low speed and improve the engine fuel consumption level, and by arranging the driver locking accessory and the anti-falling mechanism, it can prevent some parts from falling off to avoid causing harm, and improve the safety of the variable intake system.

[0005] To achieve the above object, the variable intake system is arranged in an air cleaner of a motorcycle engine, the air cleaner has an air intake box and an air intake pipe connected to the air intake box, and the variable intake system comprises a mounting portion, a driver, an extension pipe, a driver locking accessory and an anti-extrusion mechanism. The mounting portion is arranged in the air intake box. The driver is arranged on the mounting portion. The extension pipe is driven by the driving force of the driver so that the extension pipe can be selectively combined with or separated from the air intake pipe. The driver locking accessory has a bearing surface adjacent to the mounting portion to fix the driver on the mounting portion. The anti-extrusion mechanism is arranged in the air intake box. The bearing surface of the driver locking accessory and the anti-extrusion mechanism are located on the same side of the mounting portion.

[0006] The variable intake system can comprise a sliding rail which is arranged on the mounting portion by a sliding rail support. The driver can comprise a driving member and a push rod connected to the driving member, and the driving member can cause the push rod to produce linear displacement. The extension pipe can have a connecting portion which is slidably arranged on the sliding rail and connected to the push rod, wherein the push rod is driven by the driving force of the driving member so that the connecting portion can slide on the sliding rail, and the extension pipe can be selectively combined with or separated from the air intake pipe.

[0007] The driving member can be an electromagnetic valve having a magnetic member to drive the push rod.

[0008] The distance from the top of the driver locking accessory to the anti-extrusion mechanism is less than the distance from the bottom of the driver locking accessory to the bottom of the mounting portion, so as to ensure that the driver locking accessory will not be extruded out of the mounting portion and the locking position of the driver.

[0009] The anti-extrusion mechanism and the driver locking accessory can partially overlap when viewed in the side direction of the motorcycle engine.

[0010] A wall extension space can be formed between the anti-extrusion mechanism and the mounting portion, and the head of the driver locking accessory can be accommodated in the wall extension space.

[0011] The anti-extrusion mechanism and the air intake box can be an integral structure.

[0012] The driving member can be connected to the push rod by a first elastic member, and the first elastic member can be used as a source of reverse thrust.

[0013] The driving member can be electrically driven, and when the extension pipe is driven, the driving member is powered to drive, and when the extension pipe is not driven, the driving member is not powered to drive. That is, when the extension pipe needs to change the connection state with the air intake pipe, the driving member needs to be powered to drive, and the driving member does not need to be powered to drive at other times, so as to avoid overheating of the driving member.

[0014] The driving direction of the driving member is the same as the driving direction of the extension pipe, which is helpful for force transmission and reduces energy loss.

[0015] The connecting part can be connected with the push rod by a second elastic member.

[0059] Please see Figures 2 to 4, respectively, are a side view of the growth pipe and the intake pipe of the variable intake system in a separated state, a side view of the growth pipe and the intake pipe of the variable intake system in a combined state, and a structural schematic view of the driver. A variable intake system 1 is shown in the figure, which is arranged in an air cleaner 10 of a motorcycle engine. The air cleaner 10 has an intake box 101 and an intake pipe 102 connected to the intake box 101. The variable intake system 1 mainly comprises a mounting portion 2, a driver 3, a sliding rail 4, a growth pipe 5, a driver locking member 7 (as shown in Figure 5 ) and an anti-disengagement mechanism 8 (as shown in Figure 5 ).

[0060] In the embodiment, the mounting portion 2 is fixedly arranged in the intake box 101 by a plurality of locking members 20, but is not limited thereto. The mounting portion 2 and the intake box 101 can also be in an integrated structure. The driver 3 is arranged on the mounting portion 2 and comprises a driving member 31, a push rod 32, a magnetic member 33, a first elastic member 34, a wire set 35 and a sealing cover 36. In the embodiment, the driving member 31 is an electromagnetic valve driven by electricity, which can cause the push rod 32 to produce linear displacement. The magnetic member 33 is a permanent magnet, which is used to provide an adsorbing magnetic force. The first elastic member 34 is a compression spring, which is connected to the driving member 31 and the push rod 32, and is used to provide elastic restoring force. One end of the wire set 35 is connected to the driving member 31, and the other end has a connector 37, which can extend out of the intake box 101 to connect the vehicle power supply and the signal source. The sealing cover 36 is provided with the wire set 35 and arranged on the intake box 101, so that the intake box 101 still has air tightness when the wire set 35 passes through. In the embodiment, the sliding rail 4 is arranged on the mounting portion 2 by two sliding rail supports 41. The growth pipe 5 has two connecting portions 50, which are slidably arranged on the sliding rail 4 and connected to the push rod 32 by a second elastic member 62. The second elastic member 62 is a compression spring, which is used to provide elastic buffer force between the connecting portion 50 and the push rod 32 and eliminate the gap between the connecting portion 50 and the push rod 32.

[0061] As shown in Figure 2 , when the motorcycle engine reaches high speed, in order to obtain better intake efficiency, the driving member 31 of the variable intake system 1 receives a signal instruction to provide a driving force, and the elastic restoring force of the first elastic member 34 is used as a reverse thrust source to linearly drive the push rod 32 to move away from the driving member 31 side, thereby pushing the growth pipe 5 to move along the sliding rail 4 away from the intake pipe 102, and the first elastic member 34 is used to force the push rod 32 to maintain the separated state of the growth pipe 5 and the intake pipe 102, so that the overall pipe length is shortened, and the high-speed intake efficiency is improved.

[0062] As shown in Figure 3As shown, when the motorcycle engine returns to low speed, in order to achieve better intake efficiency, the driving member 31 of the variable intake system 1 will receive the signal indication to provide a driving force to linearly drive the push rod 32 to move towards the driving member 31 side until the push rod 32 abuts against the driving member 31 and the magnetic member 33 adsorbs and fixes the push rod 32 to maintain the combined state of the growth pipe 5 and the intake pipe 102, so as to increase the overall pipe length and improve the low speed intake efficiency.

[0063] In the present embodiment, the driving direction of the driving member 31 is the same as the actuation direction of the growth pipe 5, which helps to transmit force and reduce energy loss. In addition, the driving member 31 is driven by electricity, and when the growth pipe 5 is actuated, the driving member 31 is energized to drive, and when the growth pipe 5 is not actuated, the driving member 31 is not energized to drive, that is, when the growth pipe 5 needs to change the connection state with the intake pipe 102, the driving member 31 needs to be energized to drive, and the rest of the time does not need to be energized to drive, so as to avoid overheating of the driving member 31.

[0064] Please refer to Figures 5 to 8 , which are respectively Figure 3 A-A sectional view, side view of the variable intake system of the preferred embodiment of the present utility model, schematic view of wall extension space and perspective view of anti-extrusion mechanism. As shown, the driver locking member 7 of the present embodiment is a screw passing through a through hole h1 of the mounting portion 2 and locked in a locking hole h2 of the driver 3, so that the driver locking member 7 passes through a locking channel H formed by the through hole h1 and the locking hole h2 in the normal locking state, and has a bearing surface 7a close to the mounting portion 2 for fixing the driver 3 on the mounting portion 2, and the bearing surface 7a of the present embodiment is sandwiched with a gasket W between the mounting portion 2, but the gasket W can also not be provided so that the bearing surface 7a directly contacts the mounting portion 2. The anti-extrusion mechanism 8 is arranged in the intake box 101, and the anti-extrusion mechanism 8 of the present embodiment is of an integrated structure with the intake box 101, but it is not limited thereto, and other arrangement modes can also be used.

[0065] As shown in Figure 5 , the bearing surface 7a of the driver locking member 7 and the anti-extrusion mechanism 8 are located on the same side relative to the mounting portion 2, and the distance D1 from the top 71 of the driver locking member 7 to the anti-extrusion mechanism 8 is less than the distance D2 from the bottom 72 of the driver locking member 7 to the bottom 21 of the mounting portion 2, so as to ensure that the driver locking member 7 will not be extruded out of the locking channel H.

[0066] As shown in Figure 6 , viewed from the side direction of the motorcycle engine, the anti-extrusion mechanism 8 overlaps with the driver locking member 7, so as to improve the protection of the anti-extrusion mechanism 8.

[0067] As shown in Figure 7 and Figure 8As shown, the anti-disengagement mechanism 8 and the mounting portion 2 can form a wall extension space R, so that the head 70 of the driver lock accessory 7 can be accommodated in the wall extension space R and covered therein. Therefore, when the driver lock accessory 7 is disengaged, the anti-disengagement mechanism 8 can certainly stop the driver lock accessory 7 from completely disengaging from the locking passage H, avoiding falling into the air intake box 101, and further preventing the safety problem caused by inhaling the motorcycle engine.

[0068] The above embodiments are only examples for facilitating the description, and the scope of the claimed rights of the utility model should be described according to the range of the patent application file, and not limited to the above embodiments.
