Detailed Description

Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.

Fig. 1 is a schematic diagram of an engine management system according to an embodiment of the present invention. Referring to fig. 1, the engine management system 5 of the present embodiment includes a filter 10, an accelerator 20, a lubricator 30, an engine body 40, a crank position sensor 50, an intake runner 60, a butterfly valve module 100, and an engine control unit 70. The intake runner 60 communicates with the engine body 40 to supply air to the engine body 40. A filter 10 is fitted to the inlet of the inlet conduit 60 to filter air entering the inlet conduit 60. The throttle 20 and the lubricator 30 are disposed between the filter 10 and the engine body 40. The crank position sensor 50 is close to the engine body 40.

It should be noted that, in the present embodiment, the butterfly valve module 100 is connected to the intake runner 60 and located between the filter 10 and the throttle 20 for controlling the amount of gas entering the intake runner 60. The engine control unit 70 is electrically connected to at least the engine body 40 and the butterfly valve module 100. In the present embodiment, the engine control unit 70 can control the butterfly valve module 100 to make the channel 142 of the butterfly valve module 100 have three states of fully open, partially open or closed, so as to adjust the amount of gas that can be fed into the engine body 40 and control the operation rate of the engine body 40.

The butterfly valve module 100 will be explained below. FIG. 2A is a schematic diagram of a butterfly valve module of the engine management system of FIG. 1. Fig. 2B is a schematic diagram of relative positions of the rack, the gear, the first stopper and the second stopper of fig. 2A. Fig. 3A is another schematic view of fig. 2A. FIG. 3B is a schematic view of the valve plate of FIG. 2A in a fully open position.

Referring to fig. 2A to 3B, the butterfly valve module 100 of the present embodiment includes a valve seat 140 (fig. 3A), a valve plate 136 (fig. 3A), a gear 130, a rack 112, a first solenoid valve 110, a second solenoid valve 120, a first stopper 114, and a second stopper 122. As shown in FIG. 3A, the valve seat 140 has a passageway 142. The passage 142 of the valve seat 140 may communicate with the inlet conduit 60 of FIG. 1, and the valve plate 136 may be rotatably disposed within the passage 142.

In this embodiment, the gear 130 is linked to the valve plate 136, and the rotation of the valve plate 136 is driven by the gear 130. Specifically, the axial center 132 of the gear 130 is, for example, a rotation axis of the valve plate 136, and when the gear 130 rotates, the valve plate 136 rotates. Of course, in other embodiments, the axle 132 of the gear 130 and the rotating shaft of the valve plate 136 may be connected by two independent pieces, or may be not coaxial, as long as the gear 130 is linked to the valve plate 136.

The rack 112 is coupled to the first solenoid valve 110 and is adapted to move along a first axis A1. As can be seen in fig. 2B, the rack 112 is engaged with the gear 130. Therefore, the first solenoid valve 110 is operated to move the rack 112 along the first axis a1, and the gear 130 is rotated, so that the valve plate 136 is rotated.

Further, the first stopper 114 is fixed to the rack 112. In other words, when the first solenoid valve 110 operates, the rack 112 moves along the first axis a1, and the first stopper 114 moves along the first axis a 1. The second stopper 122 is linked to the second solenoid valve 120 and is adapted to move along the second axis a2 and to move in and out of the moving path of the first stopper 114.

As shown in fig. 2B and 3A, when the second stopper 122 is located on the moving path of the first stopper 114 and spaced apart from the first stopper 114, the valve plate 136 is parallel to the extending direction of the channel 142 to fully open the channel 142, and the angle between the valve plate 136 and the channel 142 is about 0 degree. At this time, the first stopper 114 is not yet blocked by the second stopper 122. As can be seen from FIG. 3B, since the valve plate 136 is parallel to the extending direction of the channel 142, the channel 142 is fully opened, and a large amount of air flow can pass through the channel 142.

In the present embodiment, the engine control unit 70 (fig. 1) is electrically connected to the first solenoid valve 110 and the second solenoid valve 120 to control the operation of the first solenoid valve 110 and the second solenoid valve 120. Of course, in other embodiments, the butterfly valve module 100 may be applied to other systems, and is not limited to the engine management system 5.

Fig. 4 is a schematic view of the first stopper being stopped by the second stopper. FIG. 5 is a schematic view of the valve plate in a partially open position. Referring to fig. 4 and 5, when the engine control unit 70 wants to adjust the ventilation of the butterfly valve module 100, the first solenoid valve 110 is instructed to actuate, the first solenoid valve 110 moves the rack 112 along the first axis a1, and the first stopper 114 moves toward the second stopper 122 and is stopped by the second stopper 122. In this process, the gear 130 is rotated by the rack 112, further rotating the valve plate 136 until the channel 142 is partially opened. At this time, the ventilation of the passage 142 is decreased by the position of the valve plate 136. Wherein the length of the stopper 122 is greater than the distance from lace 112 to the second solenoid valve 120. It should be noted that the angle of the valve plate 136 is determined by the ventilation of the channel 142, and the designer can adjust the ventilation of the channel 142 according to the requirement to determine the angle of the valve plate 136. The angle range of the valve plate 136 is, for example, between 45 degrees and 60 degrees (the angle between the valve plate 136 and the channel 142), but not limited thereto.

Fig. 6A and 6B are schematic views of the second stopper being withdrawn and the rack continuing to move along the first axis. Fig. 7A and 7B are schematic views of the valve plate in the closed position. Referring to fig. 6A to 7B, when the engine control unit 70 wants to close the ventilation of the butterfly valve module 100, the second solenoid valve 120 is first instructed to actuate, so that the second stopper 122 moves along the second axis a2 to exit the moving path of the first stopper 114. Then, the engine control unit 70 can instruct the first solenoid valve 110 to actuate, the rack 112 can continue to move along the first axis a1, the gear 130 is driven by the rack 112 to rotate, and further the valve plate 136 rotates to a state of closing the passage 142, wherein the valve plate 136 extends along the passage 142 in a direction approximately perpendicular to the passage 142, and the angle between the valve plate 136 and the passage 142 is about 90 degrees.

It should be noted that, with the above design, when the channel 142 of the butterfly valve module 100 of the engine management system 5 is fully open, since a large amount of gas can enter the engine body 40, the engine body 40 can operate fully effectively, the vehicle speed can be not limited, and the highest vehicle speed can be achieved. When the passages 142 of the butterfly valve module 100 of the engine management system 5 are partially open, only a portion of the air may enter the engine body 40, and the engine body 40 may operate only to a semi-efficient (or non-fully efficient) degree, for example, and may not achieve high vehicle speeds.

For example, when the channel 142 of the butterfly valve module 100 of the engine management system 5 is fully open, the vehicle speed may reach 60-70 km/h, and when the channel 142 of the butterfly valve module 100 of the engine management system 5 is partially open, the vehicle speed may only remain 45-48 km/h.

On the other hand, when the passage 142 of the butterfly valve module 100 of the engine management system 5 is closed, a very small amount of gas can enter the engine body 40, and the engine body 40 can only operate in the idle state.

In the present embodiment, the engine management system 5 can control the operation of the

vehicles

82 and 82a through the above-mentioned content, so that the

vehicles

82 and 82a can only run within a specific range. FIG. 8 is a schematic diagram of a virtual fence and a vehicle employing an engine management system of an embodiment of the present invention. Referring to fig. 8, such a method first defines the range of the virtual fence 80 in the space. The virtual fence 80 is defined on the map by, for example, an application software in the mobile phone. The

vehicles

82, 82a also need to have a locator 84 (e.g., GPS) corresponding to the virtual fence 80 and the engine management system 5 described above to locate the relative position of the

vehicles

82, 82a and the virtual fence 80.

Of course, the manner of defining the range of the virtual fence 80 in the space is not limited thereto. In other embodiments, a physical virtual fence device, such as a plurality of infrared emitters or magnetic strips, may be placed in the actual space. Any configuration may be used as long as the

vehicle

82 or 82a can recognize the movable range.

If

vehicles

82, 82a are beach vehicles, virtual fence 80 is located in a range suitable for driving beach vehicles, or in a range where parents want to ride a beach vehicle for teenagers. Of course, the type of

vehicle

82, 82a and the environment of application are not so limited. In other applications, it may be a kart (go car) yard that is not driven out of the yard for the purpose of managing the kart, etc.

In the present embodiment, the position of the

vehicles

82, 82a relative to the virtual fence 80 can be determined by the positioner 84 of the

vehicles

82, 82a, and the engine control unit 70 can adjust the passages 142 of the butterfly valve module 100 to be fully opened, partially opened or closed to control the operation rate of the engine body 40 according to the requirement.

Specifically, in a setting in which the all terrain vehicle can travel only within the range of the virtual fence 80, the all terrain vehicle can travel normally within the range of the virtual fence 80, but the

vehicles

82 and 82a cannot be moved away from the range of the virtual fence 80. Therefore, for example, in the vehicle 82 located in the virtual fence 80, the engine control unit 70 can control the first solenoid valve 110 and the second solenoid valve 120 of the butterfly valve module 100 to fully open the passage 142 of the valve seat 140, so as to allow a large amount of air to pass through the passage 142 and enter the engine body 40, and the engine body 40 can operate fully, so that the vehicle 82 can reach the state of the maximum vehicle speed.

For the vehicle 82a crossing the virtual fence 80, the engine control unit 70 can close the passage 142 of the butterfly valve module 100, and the engine body 40 (fig. 1) of the vehicle 82a can only operate in the idle state and cannot leave. That is, the present embodiment can control the operation rate of the engine body 40 according to the position of the

vehicles

82 and 82a relative to the virtual fence 80, so as to achieve the effect of the electric fence.

Of course, in other embodiments, to avoid the teenager's driving speed from crossing the block, the channel 142 of the butterfly valve module 100 may be partially opened when driving the beach vehicle within the range of the virtual hedge 80, and the channel 142 of the butterfly valve module 100 may be closed if the

vehicle

82, 82a crosses the virtual hedge 80.

In one embodiment, the virtual fence 80 can have multiple turns, or the engine control unit 70 can cause the channel 142 of the butterfly valve module 100 to partially open to limit the speed of the

vehicles

82, 82a when the

vehicles

82, 82a cross the inner virtual fence 80. When the

vehicles

82, 82a cross the outer virtual fence 80, the engine control unit 70 can close the passage 142 of the butterfly valve module 100, and the engine body 40 can only operate in the idle state, which is not limited in application.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
