Description

Technical Field

[0001] This utility model relates to the field of throttle valve technology, specifically a motorcycle throttle valve model and its linkage structure. Background Technology

[0002] The throttle body is a controllable valve that regulates the amount of air entering the engine. After entering the intake manifold, the air mixes with gasoline to form a combustible mixture, which then burns to produce power. There are two types of throttle bodies: traditional cable-operated and electronic. Traditional engines use a cable (soft steel wire) or lever to operate the throttle body, with one end connected to the accelerator pedal and the other to the throttle linkage plate. Electronic throttle bodies primarily use a throttle position sensor to control the throttle opening angle based on the engine's energy requirements, thereby adjusting the amount of air entering the engine. A motorcycle throttle is essentially an airflow controller. Its position sensor monitors the actual opening position of the throttle. The throttle consists of a chamber, throttle plate, throttle shaft, idle bypass passage, idle airflow control valve, position sensor, ECU module, and torsion mechanism. The torsion mechanism comprises the outer section of the throttle shaft, torsion spring, rope frame, and initial angle positioning adjustment device. The handlebars pull the rope frame via a soft steel cable, rotating the throttle shaft and throttle plate. The throttle plate opening determines the airflow within the chamber, and the torsion spring acts as the throttle plate return spring. At idle, only a small amount of air is supplied; the throttle plate opening is very small or closed, relying on the bypass passage for air supply.

[0003] For example, Chinese patent CN210509401U discloses a motorcycle throttle valve with circulating air supply and adjustable air pressure balance, belonging to the field of vehicle throttle valve technology. It includes a valve body with two intake chambers. A rotatable valve plate inside the valve body divides the intake chambers into a front chamber and a rear chamber. Each intake chamber's rear chamber has a bypass hole. An idle speed motor on the valve body controls the intake variable of the bypass hole. Each intake chamber's rear chamber has a rear intake hole. An adjustment controller on the valve body controls the constant intake of the rear intake hole. This invention can adjust the air pressure balance of the rear chambers of the two intake chambers, reducing dust accumulation in the chambers, increasing engine power, and ensuring complete and repeated combustion of exhaust gases to meet emission standards, making it more environmentally friendly.

[0004] In actual use, the technical solution described in this plan makes it difficult to disassemble and replace the valve plate. Long-term use of inferior fuel or an excessively dirty air filter will cause a large amount of carbon deposits to adhere to the valve plate. This not only affects the normal opening and closing of the valve plate, but also leads to increased wear on the valve plate surface, which in turn affects its sealing performance. In severe cases, it may cause the valve plate to deform, thereby reducing the practicality of the throttle body. Utility Model Content

[0005] The purpose of this invention is to provide a motorcycle throttle valve model and its linkage structure to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A motorcycle throttle body model and its linkage structure include a throttle body, a drive assembly, and two locking assemblies. The drive assembly is located outside the throttle body, and the locking assemblies are located inside the throttle body. The drive assembly is used to drive the throttle body to open and close. The mounting assembly is used to assemble and disassemble the valve plate. The throttle body includes a housing, and the housing has two intake chambers inside. Each intake chamber has a rotating shaft inside, and the rotating shaft has an elongated groove inside. The elongated groove has a valve plate inside, and one side of the valve plate has a sealing block. Both sides of the sealing block have through grooves, and the top and bottom of the through grooves have slots. The locking assembly includes two locking seats, which are respectively located in the two through grooves. One side of the locking seat is fixedly connected to the inner wall of the elongated groove. The top and bottom surfaces of the locking seat have square grooves, and each of the two square grooves has an insert block inside. The opposite ends of the two insert blocks engage with the two slots.

[0008] Furthermore, the locking seat has a threaded hole on its front side, and a bolt is threaded into the threaded hole. A square baffle is connected to one end of each of the two insert blocks, and a wedge block is connected to one side of each of the two square baffles. A second sliding groove is provided on one side of each of the two wedge blocks, and a second slider is slidably connected inside each of the two second sliding grooves. A movable seat is connected between a pair of second sliders. The top and bottom surfaces of the movable seat are respectively clearance-fitted with one side of each of the two wedge blocks. One end of the bolt is connected to one side of the movable seat via a bearing.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, through the cooperation of the threaded hole and the bolt, and with one end of the bolt connected to the movable seat through a bearing, when the bolt is rotated, the movable seat moves in the axial direction of the threaded hole. Due to the clearance fit between the movable seat and the wedge block and the sliding of the second slider in the second groove, the movement of the movable seat can push the wedge block to the sides or the middle, thereby controlling the extension and retraction of the insert block, thereby realizing the engagement or disengagement of the insert block with the slot, and thus realizing the locking and unlocking of the sealing block, so as to facilitate the installation and disassembly of the valve plate.

[0010] Furthermore, springs are fitted around the exterior of both inserts, with the two ends of the springs fixedly connected to the inner wall of the locking seat and one side of the square baffle, respectively.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, by setting a spring, when the moving seat moves, it pushes the wedge block to move towards the middle, so that the insert block is reset under the elastic force of the spring and retracts into the locking seat.

[0012] Furthermore, each of the two insert blocks has a first sliding groove on both outer sides at the end away from the square baffle, and a first slider is provided inside each of the two first sliding grooves. One side of each pair of first sliders is fixedly connected to the inner wall of the square groove.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, through the cooperation of the first slide groove and the first slider, the outer wall of the first slider slides in cooperation with the inner wall of the first slide groove. When the two inserts retract into the locking seat, the opposite sides of the two sets of first sliders fit against the inner side of the first slide groove near the slot, so that the top and bottom ends of the two inserts are flush with the top and bottom surfaces of the locking seat, respectively.

[0014] Furthermore, the bolt has a cross-shaped groove at the end away from the movable seat.

[0015] The advantage of adopting the above-mentioned further solution is that by providing a cross-shaped groove at the end of the bolt away from the moving seat, it is convenient for the operator to use a Phillips screwdriver to turn the bolt.

[0016] Furthermore, notches are provided on both sides of the valve plate, and a pair of limiting holes are provided inside the valve plate and the sealing block. A limiting rod is provided between the pair of limiting holes on the same side. One end of the limiting rod is fixedly connected to the inner wall of the long groove. The front and back of the valve plate are tightly fitted to one side of the sealing block and the inner wall of the long groove, respectively.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, after the sealing block is removed, the valve plate is detached from the limit rod under the action of gravity by inverting the throttle body. By setting notches on both sides of the valve plate, the valve plate is not affected by the locking seat when it detaches.

[0018] Furthermore, the two ends of the two rotating shafts are respectively connected to the inner walls of the two air intake chambers via bearings, and a coupling is provided between the two rotating shafts. The drive assembly includes a connecting seat, one side of which is fixedly connected to one side of the outer wall of the housing. A drive box is connected to the connecting seat on the side away from the housing. A brushless DC motor is installed on one side of the inner wall of the drive box. A gear is connected to the output end of the brushless DC motor. One end of one of the rotating shafts extends into the interior of the drive box and is fitted with a half gear. The half gear meshes with the gear.

[0019] The beneficial effect of adopting the above-mentioned further scheme is that by setting up a brushless DC motor, when the brushless DC motor is working, it is easy to realize the rotation of the gear. Since the gear meshes with the half gear, the half gear and one of the rotating shafts are rotated. Since a coupling is set between a pair of rotating shafts, the rotation of the two rotating shafts is realized, thereby realizing the opening and closing of the valve plates in the two intake chambers.

[0020] Furthermore, one end of one of the rotating shafts is externally connected to a throttle position sensor, the front of the drive housing is provided with a connector, and the bottom of the drive housing is provided with an ECU control unit. The connector, the throttle position sensor, and the brushless DC motor are electrically connected to the ECU control unit via wires.

[0021] The beneficial effect of adopting the above-mentioned further solution is that the throttle position sensor can detect the rotation angle of the shaft, thereby reflecting the opening state of the throttle and transmitting it to the ECU control unit. By setting a connector, the throttle position sensor is connected to the ECU control unit in the drive box. The throttle position sensor is installed at the throttle lever. The throttle position sensor detects the rotation angle of the throttle lever and transmits it to the ECU control unit. The ECU control unit can integrate the opening information of the throttle position sensor and the signal of the throttle position sensor to control the brushless DC motor, thereby adjusting the throttle opening so that the intake air volume of the engine matches the rotation angle of the throttle lever, thereby realizing the linkage between the throttle body and the throttle lever.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: When a large amount of carbon deposits adhere to the valve plate after long-term use, it easily affects the normal opening and closing of the valve plate, leading to accelerated wear on the valve plate surface. By setting a cross-shaped groove at the end of the bolt away from the moving seat, it is convenient for the operator to use a Phillips screwdriver to turn the bolt, causing the moving seat to move in the axial direction of the threaded hole. Due to the clearance fit between the moving seat and the wedge block, and the sliding of the second slider in the second groove, the movement of the moving seat can push the wedge block to the sides or center, thereby controlling the extension and retraction of the insert block, thus realizing the engagement or disengagement of the insert block with the slot, and thus realizing the locking and unlocking of the sealing block, facilitating the installation and disassembly of the valve plate. When the moving seat moves, it pushes the wedge block to the center, making... The insert blocks are reset under the elastic force of the spring and retract into the locking seat, so that the opposite sides of the two sets of first sliders are in contact with the inner side of the first slide groove near the slot, so that the top and bottom ends of the two insert blocks are flush with the top and bottom surfaces of the locking seat, respectively, realizing the separation of the insert blocks from the slot and the separation of the sealing block from the rotating shaft. After the sealing block is removed, the valve plate is detached from the limit rod under the action of gravity by inverting the throttle body. By setting notches on both sides of the valve plate, the valve plate is not affected by the locking seat when it is detached. When the brushless DC motor is working, it is easy to realize the rotation of the gear. Since the gear meshes with the half gear, the half gear and one of the rotating shafts are rotated. Since a coupling is set between the pair of rotating shafts, the rotation of the two rotating shafts is realized, realizing the opening and closing of the valve plates in the two intake chambers.

[0032] Please see Figures 1-5 This utility model provides a technical solution: A threaded hole is provided on the front of the locking seat 31, and a bolt 310 is threadedly connected inside the threaded hole. A square baffle 35 is connected to one opposite end of each of the two insert blocks 32. A wedge block 37 is connected to one opposite side of each of the two square baffles 35. A second sliding groove 38 is provided on one side of each of the two second sliding grooves 38. A second slider is slidably connected inside each of the two second sliding grooves 38. A movable seat 39 is connected between a pair of second sliders. The top and bottom surfaces of the movable seat 39 are respectively clearance-fitted with one side of each of the two wedge blocks 37.

First grooves 33 are formed on both outer sides of the two insert blocks 32 at the end furthest from the square baffle 35. First sliders 34 are provided inside each of the two first grooves 33. One side of each pair of first sliders 34 is fixedly connected to both sides of the inner wall of the square groove. A cross-shaped groove is formed on the end of the bolt 310 furthest from the moving seat 39. Notches are formed on both sides of the valve plate 14. A pair of limiting... A limiting rod 15 is provided between a pair of limiting holes 16 on the same side. One end of the limiting rod 15 is fixedly connected to the inner wall of the long groove. The front and back of the valve plate 14 are tightly fitted to one side of the sealing block 17 and the inner wall of the long groove, respectively. A cross-shaped groove is provided at the end of the bolt 310 away from the moving seat 39, which facilitates the operator to use a Phillips screwdriver to rotate the bolt 310. Through the cooperation of the threaded hole and the bolt 310, and with one end of the bolt 310 connected to the moving seat 39 through a bearing, when the bolt 310 is rotated, the moving seat 39 moves in the axial direction of the threaded hole.

[0033] 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.

[0034] Please see Figures 1-5 This utility model provides a technical solution: the two ends of two rotating shafts 13 are respectively connected to the inner walls of two intake chambers 12 via bearings, and a coupling is provided between the two rotating shafts 13. The drive assembly 2 includes a connecting seat 21, one side of which is fixedly connected to one side of the outer wall of the housing 11. A drive box 22 is connected to the side of the connecting seat 21 away from the housing 11. A brushless DC motor 23 is installed on one side of the inner wall of the drive box 22. A gear 24 is connected to the output end of the brushless DC motor 23. One end of one rotating shaft 13 extends into the interior of the drive box 22 and is fitted with a half gear 25. The half gear 25 meshes with the gear 24. A throttle position sensor 26 is externally connected to one end of one rotating shaft 13. A connecting plug 28 is provided on the front of the drive box 22. An ECU control unit 27 is provided at the bottom of the interior of the drive box 22. The connecting plug 28, the throttle position sensor 26, and the brushless DC motor 23 are electrically connected to the ECU control unit 27 via wires. By setting the brushless DC motor 23, when the brushless DC motor... When the motor 23 is working, it facilitates the rotation of the gear 24. Since the gear 24 meshes with the half gear 25, the half gear 25 and one of the rotating shafts 13 are rotated. Since a coupling is set between the pair of rotating shafts 13, the rotation of the two rotating shafts 13 is realized, realizing the opening and closing of the valve plates 14 in the two intake chambers 12. The throttle position sensor 26 can detect the rotation angle of the rotating shaft 13, thereby reflecting the throttle opening state and transmitting it to the ECU control unit 27. By setting the connector 28, the throttle position sensor is connected to the ECU control unit 27 in the drive box 22. The throttle position sensor is installed at the throttle lever. The throttle position sensor detects the rotation angle of the throttle lever and transmits it to the ECU control unit 27. The ECU control unit 27 can integrate the opening information of the throttle position sensor 26 and the signal of the throttle position sensor to control the brushless DC motor 23, thereby adjusting the throttle opening so that the intake air volume of the engine matches the rotation angle of the throttle lever, thereby realizing the linkage between the throttle body 1 and the throttle lever.

[0035] Specifically, the working principle of this motorcycle throttle valve model and its linkage structure is as follows: During use, when a large amount of carbon deposits adhere to the valve plate 14 after long-term use, it can easily affect the normal opening and closing of the valve plate 14, leading to accelerated wear on the surface of the valve plate 14. By setting a cross-shaped groove at the end of the bolt 310 away from the moving seat 39, it is convenient for the operator to use a Phillips screwdriver to turn the bolt 310, causing the moving seat 39 to move in the axial direction of the threaded hole. When the moving seat 39 moves, it pushes the wedge block 37 to move towards the center, so that the insert block 32, under the elastic force of the spring 36, The valve body is reset and retracts into the locking seat 31, causing the opposite sides of the two sets of first sliders 34 to fit against the inner side of the first slide groove 33 near the slot 19. This makes the top and bottom ends of the two inserts 32 flush with the top and bottom surfaces of the locking seat 31, respectively, thus separating the inserts 32 from the slot 19 and separating the sealing block 17 from the rotating shaft 13. After the sealing block 17 is removed, the valve plate 14 is detached from the limiting rod 15 under gravity by inverting the throttle body 1. By providing notches on both sides of the valve plate 14, the valve plate 14 does not fall off when it detaches. Due to the influence of the locking seat 31, when the brushless DC motor 23 is working, it facilitates the rotation of the gear 24. Since the gear 24 meshes with the half gear 25, the half gear 25 and one of the rotating shafts 13 are rotated. Since a coupling is set between the pair of rotating shafts 13, the rotation of both rotating shafts 13 is realized, realizing the opening and closing of the valve plates 14 in the two intake chambers 12. The throttle position sensor 26 can detect the rotation angle of the rotating shaft 13, thereby reflecting the throttle opening state and transmitting it to the ECU control unit 27. This is achieved by setting the connector 28. This connects the throttle position sensor to the ECU control unit 27 inside the drive box 22. The throttle position sensor is installed at the throttle throttle handle. The throttle position sensor detects the rotation angle of the throttle throttle handle and transmits it to the ECU control unit 27. The ECU control unit 27 can integrate the opening information of the throttle position sensor 26 and the signal from the throttle position sensor to control the brushless DC motor 23, thereby adjusting the throttle opening so that the intake air volume of the engine matches the rotation angle of the throttle throttle handle, thereby realizing the linkage between the throttle body 1 and the throttle handle.
