Description

Technical Field

[0001] The invention relates to the technical field of throttle control, and in particular to a remote control type engine throttle control device. Background Art

[0002] The engine throttle control is achieved by the full-speed governor and other operating mechanisms, including the refueling pedal and its operating structure, high-pressure diesel pump and other structures. When driving, the driver steps on the refueling pedal, which drives the longitudinal rod, vertical rod, double-arm lever, refueling rod, refueling arm and other operating structures to move, and drives the refueling arm to move in the refueling direction to achieve engine refueling control. When reducing fuel, the driver releases the refueling pedal, and under the left and right of the return spring, the refueling arm is driven to move in the direction of reducing fuel in accordance with the opposite action of refueling to achieve fuel reduction.

[0003] The traditional throttle control mechanism is manually controlled by the gas pedal, which cannot be remotely controlled, and can only judge the throttle opening subjectively, and cannot accurately adjust the throttle opening. In order to realize modern remote driving, the throttle control mechanism is optimized in the existing technology, the gas pedal and its corresponding control structure are removed, and an electric cylinder is installed to drive the gas arm to realize remote and precise control of the throttle and its opening.

[0004] The existing remote throttle control technology is only suitable for unmanned driving. When a person is driving, on the one hand, the throttle cannot be controlled by the gas pedal, which limits the throttle control method of the car itself. On the other hand, if the throttle is controlled by the gas pedal, it may conflict with the remote control. Manual control of the throttle during the remote control process will result in inaccurate throttle opening records, causing a disorder in the throttle control process. Summary of the invention

DETAILED DESCRIPTION

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the present invention provides a remote control type engine throttle control device, which has a refueling arm 1, a linkage control component 4, a remote control drive component 5, a brake cylinder cabin 6 and a hydraulic main control cabin 3 and other structures.

[0060] The refueling arm 1 is movably connected to the outer end of the refueling seat 2. The refueling arm 1 can rotate. In actual application, the refueling arm 1 itself can rotate under the operation drive, driving the refueling gear rod to move in the horizontal direction. The refueling arm 1 is installed outside the high-pressure diesel pump. Here, the refueling gear rod is suitable for a gear-type oil supply adjustment mechanism. The movement of the refueling gear rod can drive the plunger in the oil pumping mechanism to rotate. The stroke of the plunger moving upward from the radial oil hole of the plunger sleeve closed on the top surface of the plunger to the radial oil hole exposed in the plunger bevel is represented by hc. hc determines the oil supply per cycle of the injection pump. Therefore, by controlling the rotation angle of the refueling arm 1, the rotation of the plunger can be controlled, thereby controlling and adjusting hc.

[0061] The input end of the linkage operating component 4 is connected to the refueling pedal 7, and the end is arranged on the side of the refueling arm 1. The linkage operating component 4 is pressed by the refueling pedal 7 to produce a linkage action to push the refueling arm 1 to rotate at the output end. When the refueling pedal 7 is stepped on, a series of linkage actions of the linkage operating component 4 are performed to push the refueling arm 1 and push the refueling arm 1 to rotate.

[0062] The output end of the remote control driving component is directly opposite to the side of the refueling pull arm 1, and the remote control driving component 5 can drive the refueling pull arm 1 to rotate.

[0063] There are two throttle control modes in the present invention: manual control by using the gas pedal 7 and the linkage control component 4, and remote control by using the remote control drive component 5.

[0064] The brake cylinder compartment 6 is installed at the hinged end of the gas pedal 7. A brake block 8 is movably installed in the brake cylinder compartment 6. A brake groove 9 is opened on the brake block 8. An arc area for limiting the rotation of the gas pedal 7 is formed inside the brake groove 9. The brake groove 9 can support the gas pedal 7 and prevent the gas pedal 7 from rotating.

[0065] like Figure 1 As shown, one end of the hydraulic main control cabin 3 is connected to the brake cylinder cabin 6, and the other end is connected to the hydraulic cylinder 10. The output end of the hydraulic cylinder 10 is connected to the joystick 11. The joystick 11 can pass through the ends of the refueling arm 1 and the linkage control component 4 in sequence to flexibly connect the refueling arm 1 and the linkage control component 4. The hydraulic main control cabin 3 and its related structures are used to control the adjustment of different throttle control modes.

[0066] Among them, the hydraulic main control cabin 3 controls the hydraulic flow direction inside it, so that when the hydraulic pressure flows to one end of the brake cylinder cabin 6, the connection between the refueling arm 1 and the linkage operating assembly 4 is released and the brake block 8 is pushed to move and the brake groove 9 is close to the initial position of the refueling pedal 7.

[0067] In the remote throttle control mode, the hydraulic main control cabin 3 controls the hydraulic flow direction inside it, so that when the hydraulic pressure flows to one end of the brake cylinder cabin 6, the connection between the refueling pull arm 1 and the linkage control assembly 4 is released and the brake block 8 is pushed to move, and the brake groove 9 is close to the initial position of the refueling pedal 7, thereby braking the refueling pedal 7;

[0068] In the manual throttle control mode, the hydraulic main control cabin 3 controls the hydraulic flow direction therein to re-establish the connection between the refueling arm 1 and the linkage control assembly 4 when the hydraulic pressure flows to one end of the hydraulic cylinder 10 and push the brake block 8 to reset its movement. The brake groove 9 no longer brakes the movement of the refueling pedal 7. At this time, the throttle can be controlled by stepping on the refueling pedal 7.

[0069] In the present invention, manual control of the throttle is achieved through the gas pedal 7, and remote control control of the throttle is achieved through the remote control drive assembly 5, which increases the control methods of the throttle and improves the adaptability of the throttle control device.

[0070] In the present invention, Figure 5 , Figure 6 As shown, a brake groove 9 is provided at the hinged end of the gas pedal 7, and an area for limiting the rotational movement of the gas pedal 7 is formed inside the brake groove 9. During the remote control of the throttle, the connection between the gas arm 1 and the linkage control assembly 4 is released, and the throttle can only be controlled by remote control driving in this state. In addition, the movement of the gas pedal 7 is also limited, which, on the one hand, avoids interference between the remote control throttle control mode and the manual throttle control mode, and on the other hand, reminds the driver during remote control operation to avoid damage to the gas pedal 7 and its connection structure caused by the driver's high-frequency pressing of the gas pedal in a hurry.

[0071] In the present invention, Figure 5 and Figure 6 As shown, the brake block 8 is a cylindrical structure, and a hydraulic groove 12 is formed on one side wall of the brake block 8 away from the brake groove 9. The groove surfaces formed by the hydraulic groove 12 and the brake groove 9 on the brake block 8 are both arc surfaces.

[0072] like Figure 6 As shown, a hydraulic port 13 is provided on the outer wall of the brake cylinder compartment 6, and the hydraulic port 13 is opposite to the hydraulic groove 12. In actual application, it should be ensured that: when the brake groove 9 moves to brake the gas pedal 7, the hydraulic port 13 is still opposite to the hydraulic groove 12, so that the liquid can be extracted later, and during the liquid extraction process, the brake block 8 and the brake groove 9 can also be reset under the action of negative pressure.

[0073] Among them, the maximum radius of the brake block 8 is equal to the inner diameter of the brake cylinder compartment 6. Except for the groove area of ​​the hydraulic groove 12 and the brake groove 9, the radius of other parts of the brake block 8 is equal to the inner diameter of the brake cylinder compartment 6. This design enables the outer wall of the brake block 8 on the side of the hydraulic groove 12 to completely fit the inner wall of the brake cylinder compartment 6, thereby preventing liquid from overflowing along the gap.

[0074] In order to realize the braking of the gas pedal 7, the present invention also makes the following design, such as Figure 6 and Figure 7 As shown, a brake rod 14 is connected to the bottom of the gas pedal 7, and a slot 15 for the brake rod 14 to pass through is formed on the outer wall of the brake cylinder compartment 6.

[0075] Assuming that the initial state is in remote control mode, one of the groove edges of the brake groove 9 corresponds to the groove edge position of the slot 15 and is away from the side of the brake rod 14. After the brake block 8 rotates clockwise, the groove edge of the brake groove 9 gradually supports the side of the brake rod 14, and the gas pedal 7 rotates under force and needs to resist the hydraulic pressure formed at the hydraulic port 13;

[0076] Then it is switched to manual control mode, the liquid in the hydraulic tank 12 is pumped out, and under the action of negative pressure, the brake block 8 rotates and returns to the initial position.

[0077] In order to further increase the resistance to the movement of the gas pedal 7, the present invention further designs that the distance from the braking point of the brake rod 14 in the brake groove 9 to the central axis is smaller than the distance from the action point of the liquid in the hydraulic groove 12 to the central axis.

[0078] In the above embodiment, the braking point refers to the point where the force is generated. The central axis point of the brake block 8 itself can be regarded as a fulcrum (the central axis point corresponding to the hinge shaft 45). The power generated by the activity of the gas pedal 7 is resisted by the resistance generated by the hydraulic pressure. When the gas pedal 7 is about to move, Fig. 9 The circles shown in the figure indicate the braking points. Figure 8 The circle shown in the figure indicates the point where the liquid acts on the hydraulic groove 12. The distance from the braking point of the brake rod 14 in the brake groove 9 to the central axis is equivalent to the power arm. The distance from the point where the liquid acts on the hydraulic groove 12 to the central axis is equivalent to the resistance arm. The power arm is smaller than the resistance arm, so that the power needs to be greater than the resistance to drive the gas pedal 7 to move. In addition, the power also needs to resist the friction between the brake block 8 and the hinge shaft 45. That is to say, the power to drive the gas pedal 7 to move must be large enough, and the driver's feet usually cannot apply enough power to make the gas pedal 7 move. Therefore, the above design can further achieve the braking effect of the gas pedal 7 under remote control.

[0079] In order to realize the conversion between manual throttle control and remote throttle control, the present invention makes the following design: Figure 5 , Figure 6 and Figure 7 As shown, one end of the hydraulic main control cabin 3 is connected to a first hydraulic pipe 16, and the other end is connected to a second hydraulic pipe 17, the end of the first hydraulic pipe 16 is connected to the hydraulic port 13, and the end of the second hydraulic pipe 17 is connected to the hydraulic cylinder 10;

[0080] A partition 18 is installed in the middle of the hydraulic main control cabin 3, and a horizontal connecting rod 19 is provided through the partition 18. One end of the horizontal connecting rod 19 is connected to a first hydraulic plate 20, and the other end is connected to a second hydraulic plate 21. The first hydraulic plate 20 and the second hydraulic plate 21 are installed on both sides of the partition 18;

[0081] The hydraulic main control cabin 3 is respectively connected with a first liquid pipe 22 and a second liquid pipe 23 . The first liquid pipe 22 is directly opposite to between the first hydraulic plate 20 and the partition 18 , and the second liquid pipe 23 is directly opposite to between the second hydraulic plate 21 and the partition 18 .

[0082] The hydraulic main control cabin 3 is externally connected to a main control module, and the main control module receives remote control commands to control the liquid inlet and outlet of the first liquid pipe 22 and / or the second liquid pipe 23 .

[0083] In the present invention, injecting liquid into the first liquid pipe 22 or extracting liquid out of the second liquid pipe 23 can drive the first hydraulic plate 20 and the second hydraulic plate 21 to move leftward, and injecting liquid into the second liquid pipe 23 or extracting liquid into the first liquid pipe 22 can drive the first hydraulic plate 20 and the second hydraulic plate 21 to move rightward.

[0084] Assuming that the initial state is the manual throttle control mode, the first hydraulic plate 20 is closer to the partition 18. If it is to be adjusted to the remote control state, injecting liquid into the first liquid pipe 22 or extracting liquid out of the second liquid pipe 23 can drive the first hydraulic plate 20 and the second hydraulic plate 21 to move left, so that the liquid enters the brake cylinder compartment 6, and under the action of the hydraulic pressure, the brake block 8 is pushed to rotate clockwise, driving the brake groove 9 to abut against the side of the brake rod 14.

[0085] The present invention realizes manual throttle control through the linkage control component 4, and the linkage control component 4 adopts the following preferred embodiments, such as Figure 2 As shown, the linkage control assembly 4 includes a torsion seat 41, a longitudinal pull rod 42, a tilt pull rod 43, and a refueling pull rod 44 which are arranged in sequence;

[0086] The gas pedal 7 is rotatably mounted on the torsion seat 41 via an articulated shaft 45. One end of the longitudinal pull rod 42 is rotatably connected to a first rotating bolt 46, and the other end is rotatably connected to a second rotating bolt 47. The end of the first rotating bolt 46 is connected to the articulated shaft 45, and the end of the second rotating bolt 47 is connected to a horizontal shaft 48. A fixed seat 49 is installed on the side of the horizontal shaft 48. A third rotating bolt 410 is connected to the horizontal shaft 48, and the end of the third rotating bolt 410 is hinged to the tilt pull rod 43.

[0087] The end of the tilting rod 43 is hinged with the end of the refueling rod 44. A limiting cylinder 411 is arranged on the periphery of the tilting rod 43. The tilting rod 43 is slidably arranged in the limiting cylinder 411. The limiting cylinder 411 is tilted and a spring is installed inside the limiting cylinder. The spring is connected to the tilting rod 43.

[0088] The inner side of the limiting cylinder 411 can be rotatably mounted on the frame structure via a rotating shaft.

[0089] Assuming that it is in the manual operation mode, the refueling rod 44 can push and pull the refueling arm, and the refueling pedal 7 is stepped on, so that the hinge shaft 45 rotates counterclockwise on the torsion seat 41, driving the first rotating bolt 46 to rotate, driving the longitudinal rod 42 to move, thereby driving the second rotating bolt 410 to rotate counterclockwise, driving the horizontal shaft 48 to rotate counterclockwise on the fixed seat 49, and driving the third rotating bolt 410 to rotate counterclockwise through the horizontal shaft 48, thereby driving the tilting rod 43 to rotate clockwise around the limiting cylinder 411, and the top end of the tilting rod 43 pushes the refueling rod 44 in the counterclockwise direction, pushing the operating lever 11 to move to the right, thereby pushing the refueling arm 1 to rotate clockwise.

[0090] When the gas pedal 7 is released, under the action of the spring, the tilting rod 43 is reset, driving other structures to reset. In addition, the gas pedal 7 itself is also provided with a reset spring, and the reset of the gas pedal 7 can drive other structures to reset completely.

[0091] The present invention also has the following design: the articulated shaft 45 passes through the brake pad 8, and the friction force between the articulated shaft 45 and the brake pad 8 is smaller than the friction force between the brake pad 8 and the brake cylinder compartment 6. During the rotation of the gas pedal 7, the articulated shaft 45 is driven to rotate. In order to avoid the brake pad 8 being driven to rotate during the rotation of the articulated shaft 45, it is necessary to make the friction force between the brake pad 8 and the brake cylinder compartment 6 able to resist the friction force between the articulated shaft 45 and the brake pad 8. When relative movement occurs between the articulated shaft 45 and the brake pad 8 (during the rotation of the articulated shaft 45), the brake pad 8 can also remain in a relatively static state in the brake cylinder compartment 6.

[0092] In the present invention, Figure 2As shown, the joystick 11 is arranged horizontally, a first through hole 412 is formed at the end of the refueling pull rod 44 away from the inclined pull rod 43, and a second through hole 413 is formed at the end of the refueling pull arm 1, and the outer diameter of the joystick 11 is consistent with the inner diameter of the first through hole 412 and the second through hole 413, and the joystick 11 is directly opposite to the first through hole 412 and the second through hole 413.

[0093] Under the push of the output end of the hydraulic cylinder 10 , the joystick 11 can be inserted into the first through hole 412 and the second through hole 413 , so that the refueling pull rod 44 moves rightward and can push the refueling pull arm 1 to rotate clockwise.

[0094] In order to make the joystick 11 face the first through hole 412 and the second through hole 413, it is necessary to ensure that there is a certain angle between the refueling rod 44 and the tilting rod 43 in the initial state. A strong torsion spring can also be installed between the tilting rod 43 and the refueling rod 44. Under the action of the torsion spring, there is a certain angle between the refueling rod 44 and the tilting rod 43 in the absence of external force.

[0095] In order to prevent the joystick 11 itself from being dragged by the output shaft, the present invention further makes the following design: a magnetic block 24 is provided at one end of the output shaft of the hydraulic cylinder 10, a magnet is provided at one end of the joystick 11 close to the output shaft, the magnet is facing the magnetic block 24, and a movable shaft rod 25 is installed at the end of the refueling arm 1 away from the joystick 11, and the refueling arm 1 is rotatably installed on the refueling seat 2 through the movable shaft rod 25.

[0096] The joystick 11 can be moved along the length direction to push the joystick 11 into the first through hole 412 and the second through hole 413 through the output shaft. During this process, the magnet and the magnetic block 24 are attracted to each other. When the joystick 11 rotates around the movable shaft 25 under the push of the refueling pull rod 44, the magnet is separated from the magnetic block 24. In addition, when it is necessary to release the linkage between the refueling pull arm 1 and the refueling pull rod 44, the joystick 11 follows the refueling pull arm 1 to reset to the initial position. Under the action of magnetic force, the magnet is attracted to the magnetic block 24 and drives the joystick 11 to move along the length direction of the joystick 11 through the output shaft to drive the joystick 11 to separate from the first through hole 412.

[0097] In summary, the main implementation process of the present invention is:

[0098] Assuming that the initial state is the manual throttle mode, the first hydraulic plate 20 is closer to the partition 18,

[0099] Adjust the throttle mode from manual to remote control mode:

[0100] Injecting liquid into the first liquid pipe 22 or extracting liquid out of the second liquid pipe 23 can drive the first hydraulic plate 20 and the second hydraulic plate 21 to move leftward, so that the liquid enters the brake cylinder compartment 6, and under the action of the hydraulic pressure, the brake block 8 is pushed to rotate clockwise, driving the brake groove 9 to abut against the side of the brake rod 14, thereby preventing the gas pedal 7 from moving;

[0101] Under the action of negative pressure, the output shaft moves toward the side away from the joystick 11, driving the joystick 11 to move along the length direction of the joystick 11, and driving the joystick 11 to disengage from the first through hole 412 through the output shaft. At this time, the refueling pull rod 44 can no longer drive the refueling pull arm 1 to move;

[0102] The refueling arm 1 is driven by the remote control driving component 5 to move.
