This will not only cause trouble to the rider, but may also affect the riding safety. Therefore, the aforementioned patent still has room for improvement in terms of structure.

The main purpose of the present invention is to provide an electronic control device with a sound generator, which can emit a sound to remind the rider when the operation is completed, so that the rider can grasp the driving status at any time to improve the safety of riding.

In order to achieve the above main purpose, the electronic control device of the present invention includes a base, at least one sound generator, an operating rod, and a control unit. The base has a chamber; the sound generator is arranged in the chamber of the base to emit a prompt sound, the sound generator has an outer tube, a moving part, a rotating part, and a first elastic part, the outer tube has an axial hole, and one end of the outer tube has a first opening connected to the axial hole, the moving part can be axially displaced in the axial hole of the outer tube, and the outer peripheral surface of the moving part has A plurality of first teeth and a plurality of second teeth, one end of the moving member forms a pressing portion through the first opening, the first teeth and the second teeth are arranged in a staggered annular arrangement, the rotating member is axially displaceable and rotatable in the axial hole of the outer cylinder, the outer peripheral surface of the rotating member has a plurality of second teeth arranged in annular intervals, the first elastic member acts on the rotating member The rotating member is pushed toward the moving member, wherein when the moving member is in a release position, the first teeth of the moving member and the second teeth of the rotating member abut against each other, and when the moving member is in a pressure position, the first teeth of the moving member and the second teeth of the rotating member stagger with each other, and the other end of the moving member and the second teeth of the rotating member are in contact with each other. abut against each other; the operating rod is arranged on the base and adjacent to the sounder; the control unit is arranged in the chamber of the base for sending a signal; wherein, when the operating rod is actuated by an external force, the moving part is driven by the operating rod to move from the release position to the pressure position, so that the sounder emits the prompt sound, and the control unit is triggered by the operating rod to send the signal.

From the above, it can be seen that the electronic control device of the present invention will use the sound generator to emit a sound to remind the rider when the operation is completed, so that the rider can grasp the driving status at any time, thereby achieving the purpose of improving riding safety.

Preferably, the sound generator further has a second elastic member, which is disposed between the moving member and the rotating member and pushes the moving member away from the rotating member to provide a reset force for the moving member.

Preferably, the hole wall of the axial hole of the outer cylinder has a plurality of limiting grooves, and the first teeth of the movable member are displaceably embedded in the limiting grooves of the outer cylinder. Thus, when the movable member is pushed up by the operating rod, it can only be linearly displaced along the axial direction of the axial hole without rotating.

Preferably, the end of each first tooth has a first inclined surface, and the end of each second tooth has a second inclined surface. When the moving member is located at the release position, the first inclined surfaces of the first teeth abut against the second inclined surfaces of the second teeth. Thus, when the moving part of the moving part is pressed by an external force, the moving part will push the second inclined surfaces of the rotating part through the first inclined surfaces, causing the rotating part to move back and rotate, and compress the first elastic part and the second elastic part at the same time, until the first inclined surfaces and the second inclined surfaces are offset, the rotating part will move toward the moving part through the elastic restoring force released by the second elastic part, causing the second teeth of the moving part and the second teeth of the rotating part to collide with each other and make a sound.

Thereby, the first elastic member provides elastic force to push the rotating member toward the moving member.

Preferably, one of the sound generators is disposed on two opposite sides of the operating rod. When the operating rod pivots toward the first direction, the operating rod pushes the moving part of one of the sound generators from the release position to the pressure position, so that the second teeth of the moving part and the second teeth of the rotating part collide with each other to emit the prompt sound. When the operating rod pivots toward the second direction, the operating rod pushes the moving part of the other sound generator from the release position to the pressure position, so that one end of the other moving part and the second teeth of the other rotating part collide with each other to emit the prompt sound.

Preferably, one side of the base further has a side opening connected to the chamber. The operating rod has a pivot part, a rod, a first operating part, a second operating part, an arm and an action part.

The other end is located between the speakers, and the action part is connected to the end of the arm, wherein when the first operation part of the operating lever is acted upon by an external force, the operating lever rotates in the first direction and pushes the moving part of one of the speakers with one end of the action part, and when the second operation part of the operating lever is acted upon by another external force, the operating lever rotates in the second direction and pushes the moving part of another speaker with the other end of the action part. In this way, the operating lever sets the first operation part and the second operation part on the same side, so that the rider can operate more intuitively and conveniently, thereby improving the convenience of operation.

Preferably, when the external force on the first operating part of the operating rod is eliminated, the movable member applies a reset force to the action part of the operating rod through the elastic restoring force released by the first elastic member, so that the operating rod returns from a first position to an initial position in the second direction; conversely, when the external force on the second operating part of the operating rod is eliminated, the other movable member applies a reset force to the action part end of the operating rod through the elastic restoring force released by another first elastic member, so that the operating rod returns from a second position to the initial position in the first direction.

Preferably, the control unit has a circuit board, a first reed switch, a second reed switch and a magnet. The first reed switch and the second reed switch are both electrically connected to the circuit board and are located on two opposite sides of the operating rod. The magnet is embedded in the operating rod and is located between the first reed switch and the second reed switch. Thus, when the operating rod rotates in the first direction, the magnet approaches the first reed switch to turn it on, thereby causing the circuit board to send the signal. When the operating rod rotates in the second direction, the magnet approaches the second reed switch to turn it on, thereby causing the circuit board to send the signal.

As can be seen from the above, when the operating lever 80 has not been moved by the rider and is located at the initial position P1 as shown in FIG. 4 , the moving member 50 is located at the release position P4 as shown in FIG. 4 due to no external force. At this time, the first inclined surfaces 55 of the first teeth 54 of the moving member 50 and the second inclined surfaces 66 of the second teeth 63 of the rotating member 60 abut against each other.

When the rider pushes the first operating portion 84 backward with the index finger of his right hand, the operating lever 80 rotates in a first direction D1 from the initial position P1 shown in FIG. 4 to the first position P2 shown in FIG. 5 .

During the movement, the first elastic member 72 and the second elastic member 70 are compressed at the same time. , so that the first elastic member 72 and the second elastic member 70 respectively accumulate elastic restoring force until the first inclined surfaces 55 and the second inclined surfaces 66 are offset, and the rotating member 60 moves toward the moving member 50 through the elastic restoring force released by the first elastic member 72, so that one end of the moving member 50 and the second teeth 63 of the rotating member 60 abut against each other and emit a prompt sound. At this time, the moving member 50 is located at the pressure position P5 as shown in Figure 5. Once the external force applied to the first operating portion 84 disappears, the moving member 50 will apply a reset force to the first action end 872 of the operating rod 80 through the elastic restoring force continuously released by the first elastic member 72 and the second elastic member 70, so that the operating rod 80 returns from the first position P2 shown in FIG. 5 to the initial position P1 shown in FIG. 4 in the second direction D2.

On the other hand, when the rider pushes the second operating portion 85 forward with the right thumb, the operating lever 80 rotates in the second direction D2 from the initial position P1 shown in FIG. 4 to the second position P3 shown in FIG. 6 . At this time, the magnet 94 approaches the second reed switch 93 to turn it on, thereby causing the circuit board 91 to send a second signal (downshift signal) to the motor 14 (as shown in FIG. 7 ), and the motor 14 can drive the sprocket 14 to perform the downshift action. At the same time, as shown in FIG. 6 , the operating rod 80 pushes the moving member 50 with the second action end 874, so that the moving member 50 pushes the second inclined surfaces 66 of the rotating member 60 through the first inclined surfaces 55. At this time, the rotating member 60 moves away from the moving member 50 along the axis of the through hole 53 and rotates around the axis of the through hole 53. During the movement, the first elastic member 72 and the second elastic member 7 are compressed. 0, so that the first elastic member 72 and the second elastic member 70 accumulate elastic restoring force until the first inclined surfaces 55 and the second inclined surfaces 66 are offset, and the rotating member 60 moves toward the moving member 50 through the elastic restoring force released by the first elastic member 72, so that one end of the moving member 50 and the second teeth 63 of the rotating member 60 abut against each other to emit a prompt sound. At this time, the moving member 50 is located at the compressed position P5 as shown in FIG. 6. Once the external force applied to the second operating portion 85 disappears, the moving member 50 will apply a reset force to the second action end 874 of the operating rod 80 through the elastic restoring force continuously released by the first elastic member 72 and the second elastic member 70, so that the operating rod 80 returns from the second position P3 shown in FIG. 6 to the initial position P1 shown in FIG. 4 in the first direction D1.

In summary, the electronic control device 10 of the present invention will use one of the speakers 30 to emit a sound to remind the rider when the gear shift is completed, so that the rider can grasp the driving status at any time, thereby achieving the purpose of improving riding safety. In addition, the electronic control device 10 of the present invention sets the first operating part 84 and the second operating part 85 on the same side of the operating lever 80, so that the rider can complete the operation with two fingers of the same hand when switching gears, which is more intuitive and convenient in operation, thereby achieving the purpose of increasing the convenience of operation.
