[0030] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the present invention. As used in the specification and appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0031] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0032] Combine Figure 1-8As shown, an embodiment of the present invention provides an electronic throttle structure for use on a speed-variable bicycle, comprising: a throttle base 1, on which a control module 11 is provided, and on which a first control component and a second control component are provided; a turning handle 2, which is provided on one side of the throttle base 1 and can rotate relative to the throttle base 1, and on which a trigger component is provided. When the turning handle 2 rotates to a first predetermined position, the trigger component contacts the first control component to generate a first control signal. When the turning handle 2 rotates in the opposite direction to a second predetermined position, the trigger component contacts the second control component to generate a second control signal.

[0033] In an embodiment of the present invention, two control members are provided on the control module 11 to respectively control upshifting and downshifting. When the handle 2 rotates to the first predetermined position and the second predetermined position, it contacts one of the control members, thereby generating a control signal and triggering one of the upshifting and downshifting operations. Compared with the wire-pulling device used in existing handles, the handle equipped with the control module 11 has a simple structure and accurate and efficient gear shifting. Specifically, the first predetermined position and the second predetermined position are respectively close to two different directions of the handle 2. For example, when the handle 2 rotates clockwise to the first predetermined position, the trigger member contacts the first control member, triggering the upshifting operation. When the handle 2 rotates counterclockwise to the second predetermined position, the trigger member triggers the second control member, triggering the downshifting operation. The handle 2 that controls the upshifting and downshifting operations rotates in different directions. This embodiment makes the gear shifting operation faster and more accurate, and is less likely to cause gear shifting errors.

[0034] Furthermore, a shaft 12 is provided on one side of the turning handle 1, a first control member and a second control member are provided in the shaft 12, a trigger member is protruded on the turning handle 2 and inserted into the shaft 12, and the trigger member is located between the first control member and the second control member.

[0035] In this embodiment, the trigger member is protruding from the turning handle 2 and inserted into the shaft 12, and is located between the two control members, so that the turning handle 2 can be rotated in two different directions to trigger one of the control members respectively, thereby generating a control signal and triggering one of the upshift and downshift operations respectively. The internal structure of the turning handle 2 and the turning handle base 1 is simple, and the upshift and downshift operations can be operated by rotating the turning handle 2, which is easy and quick.

[0036] Combine Figure 1-4 As shown, the first control member and the second control member are respectively the first electronic button 114 and the second electronic button 115, and the trigger member is the arc-shaped protrusion 21. When the handle 2 rotates to the first predetermined position, the arc-shaped protrusion 21 contacts the first electronic button 114, generating a first control signal. When the handle 2 rotates in the opposite direction to the second predetermined position, the arc-shaped protrusion 21 contacts the second electronic button 115, generating a second control signal.

[0037] In this embodiment, two opposing electronic buttons are provided on the control module 11. Rotating the handle 2 to the first and second predetermined positions triggers one of the electronic buttons, generating a control signal and initiating one of the shift-up and shift-down operations. Compared to conventional throttles employing cable-pull devices, the throttle equipped with the control module 11 having two opposing electronic buttons has a simpler structure and offers accurate and efficient shifting. Specifically, both electronic buttons are integrated. For example, the second electronic button 115 has a button spring 1151 disposed outwardly at one end. An electronic controller 1152 is housed within the second electronic button 115, which is used to trigger the control module 11 to generate a control signal and initiate one of the shift-up and shift-down operations. The button springs 1151 facilitate rapid activation of the electronic controller 1152 upon contact with the arc-shaped protrusion 21. More specifically, the button springs 1151 are provided on either side of the arc-shaped protrusion 21. When the handle 2 rotates to the first and second predetermined positions, the button springs 1151 contact and trigger the electronic button to generate a control signal, thereby initiating one of the shift-up and shift-down operations.

[0038] Combine Figure 5-8 As shown, the first control member and the second control member are respectively a first contact 111 and a third contact 113, a second contact 112 is provided between the first contact 111 and the third contact 113, and the trigger member is an arc-shaped conductive piece 22, which is always in contact with the second contact 112. When the handle 2 rotates to a first predetermined position, the arc-shaped conductive piece 22 contacts the first contact 111, generating a first control signal. When the handle 2 rotates in the opposite direction to a second predetermined position, the arc-shaped conductive piece 22 contacts the third contact 113, generating a second control signal.

[0039] In this embodiment, three contacts arranged in sequence are provided on the control module 11, and two of the contacts will be triggered respectively when the handle 2 rotates to the first predetermined position and the second predetermined position, thereby generating a control signal and triggering one of the upshift and downshift operations respectively. Compared with the wire pulling device used in the existing handle, the handle equipped with the control module 11 having the above three contacts arranged in sequence has a simple structure and the gear shifting is accurate and efficient.

[0040] Specifically, the throttle base 1 is further provided with a housing 13 connected to the shaft 12. The control module 11 includes a power supply 116 and a first PCB 117. The power supply 116 and the first PCB 117 are disposed within the housing 13 and serve to connect the first and second control components. The housing 13 is provided with a first power supply cover 131 and a second power supply cover 132 for accommodating and protecting the power supply 116. A recessed area in the middle of the second power supply cover 132, away from the first power supply cover 131, provides a space for accommodating the power supply 116. The first and second power supply covers 131 and 132 fit snugly together, and a sealing ring 133 is provided at the joint to seal the power supply. In this embodiment, the housing 13 provides a larger space for the throttle base 1, facilitating the placement of the PCB containing the shift control circuitry. It also aligns the internal structure of the throttle, minimizing component interference. Furthermore, the first power supply cover 131 can be removed for battery replacement. Specifically, the first PCB 117 is secured with four screws and a waterproof rubber ring, ensuring a waterproof and dustproof design.

[0041] More specifically, the control module 11 also includes a second PCB 118, which is arranged in the shaft portion 12, the first PCB 117 is connected to the second PCB 118, the first contact 111, the second contact 112 and the third contact 113 are arranged on the second PCB 118, the arc-shaped conductive sheet 22 is opposite to the second PCB 118, the second contact 112 is always in contact with the inner arc of the trigger member, and the second contact 112 is higher than the first contact 111 and the third contact 113.

[0042] In this embodiment, the arc-shaped conductive sheet 22 is always in contact with the second contact 112. That is, when the handle 2 is in the initial position, the second contact 112 is in contact with the middle position of the arc-shaped conductive sheet 22. When the handle 2 is rotated to the first predetermined position or the second predetermined position, the second contact 112 will never leave the inner arc range of the arc-shaped conductive sheet 22. The second contact 112 is higher than the first contact 111 and the third contact 113. This can prevent the first contact 111 and the third contact 113 at the two ends of the second PCB 118 from easily contacting the arc-shaped conductive sheet 22 when the handle 2 is in the initial position because the two ends of the second PCB 118 are closer to the arc-shaped trigger member in the middle.

[0043] In one embodiment, the first contact 111 and the third contact 113 are tilted outward, placing the tops of the two contacts at a greater distance from the trigger element, thereby preventing the two contacts from accidentally contacting the arc-shaped conductive sheet 22 and causing a shift error. In a more specific embodiment, the first, second, and third contacts are all metal springs, and the arc-shaped conductive sheet 22 is a conductive sheet. The essence of the shift up / down operation is that the arc-shaped conductive sheet 22 contacts the first contact 111 and the second contact 112, or contacts the second contact 112 and the third contact 113, connecting the shift up / down circuit on the control module 11. Therefore, the first contact 111, the second contact 112, the third contact 113, and the trigger element are all made of conductive materials, facilitating the rapid execution of the shift up / down operation.

[0044] Furthermore, the turning handle base 1 is provided with an elastic component 14, and the turning handle 2 is connected to the elastic component 14. When the turning handle 2 rotates to the first predetermined position or the second predetermined position, the elastic component 14 is subjected to force and drives the turning handle 2 to reset.

[0045] In this embodiment, when the turning handle 2 reaches the first predetermined position or the second predetermined position, a control signal is generated and one of the gear shifting operations is triggered. At the same time, the elastic component 14 is arranged on the turning handle base 1, and the turning handle base 1 is stationary, that is, one end of the elastic component 14 is stationary, and the other end of the elastic component 14 is connected to the turning handle 2. Regardless of whether the turning handle 2 rotates clockwise or counterclockwise, the elastic component 14 is compressed or tightened. The rebound or contraction of the elastic component 14 will reset the turning handle 2, which is convenient for the subsequent gear change operation.

[0046] Combine Figure 1 As shown, the turning handle 2 is provided with a connecting shaft 24 inserted into the shaft portion 12, and the elastic component 14 includes a first elastic member 143 with one end sleeved on the connecting shaft 24. One end of the first elastic member 143 is connected to the turning handle 2, and the other end is connected to the turning handle base 1.

[0047] In this embodiment, the first elastic member 143 is sleeved on the connecting shaft 24. Since it is coaxially arranged with the turning handle 2, no matter whether the turning handle 2 rotates clockwise or counterclockwise, the elastic member is compressed or tightened, thereby resetting the turning handle 2 to facilitate the next gear shifting operation.

[0048] Combine Figure 5As shown, the elastic component 14 includes a connecting member 141 and two second elastic members 142. The connecting member 141 is slidably mounted on the turning handle base 1 and is connected to the turning handle 2. The two second elastic members 142 are respectively located on both sides of the connecting member 141. The two second elastic members 142 are both in a stretched state. When the turning handle 2 is rotated to the first predetermined position or the second predetermined position, one second elastic member 142 is stretched and the other second elastic member 142 is released and returns to its position; or, the two second elastic members 142 are both in a free state. When the turning handle 2 is rotated to the first predetermined position or the second predetermined position, one second elastic member 142 is squeezed and the other second elastic member 142 is stretched.

[0049] In this embodiment, the connection of both second elastic members 142 to the connecting member 141 is equivalent to the connection of both second elastic members 142 to the turning handle 2. During the rotation of the turning handle 2, one of the second elastic members 142 is stretched while the other second elastic member 142 releases the force and returns to its original position, or one second elastic member 142 is squeezed while the other second elastic member 142 is stretched, both of which cause the two second elastic members 142 to return to their initial positions, thereby resetting the turning handle 2. Specifically, the turning handle 2 is provided with a mounting portion 25, on which the arc-shaped conductive sheet 22 is disposed. The connecting member 141 is slidably mounted on the turning handle base 1 and connected to the mounting portion 25, facilitating clockwise or counterclockwise rotation of the turning handle 2.

[0050] Furthermore, the electronic throttle structure further includes a limiting member 3 , which is disposed on the other side of the throttle base 1 , and the throttle base 1 is fixedly mounted on the speed-changing bicycle via the limiting member 3 .

[0051] In this embodiment, the limiting member 3 secures the throttle base 1 to the speed-shifting bicycle. During the rotation of the turning handle 2, the throttle base 1 does not rotate, allowing the trigger member to contact the two control members on the control module 11, thereby achieving the upshift and downshift operation. Specifically, the limiting member 3 includes a snap ring 31 and a fastener 32. The snap ring 31 has two opposing end portions, each of which is provided with a through hole 33. The fastener 32 connects the two through holes 33. The two end portions are in contact with one end surface of the throttle base 1. One side of the limiting member 3 is in contact with a side surface of the throttle base 1, thereby limiting the position of the throttle base 1 and preventing the throttle base 1 from rotating or moving. The fixed position of the throttle base 1 can be adjusted by adjusting the tightness of the fastener 32.

[0052] Furthermore, an arc-shaped groove 15 is formed on one side of the throttle base 1 , a connecting piece 16 sliding in the arc-shaped groove 15 is provided in the throttle base 1 , and a protrusion 23 connected to the connecting piece 16 is provided on the turning handle 2 .

[0053] In this embodiment, the connecting member 16 and the protrusion 23 are connected and can slide along the arc groove 15, which not only connects the throttle base 1 and the turning handle 2, but also allows the turning handle 2 to rotate relative to the throttle base 1, making the shifting operation simple and easy.

[0054] The present invention also provides a speed-changing bicycle, comprising a bicycle body and the electronic handlebar structure as described above.

[0055] In an embodiment of the present invention, a bicycle body using the electronic throttle structure as described above is provided with two control components for respectively controlling upshifting and downshifting on the control module 11. During riding, rotating the throttle 2 to a first predetermined position or a second predetermined position generates a control signal and triggers one of the upshifting and downshifting operations respectively. Compared with the cable pulling device used in the existing throttle, the throttle equipped with the control module 11 has a simple structure and can shift gears accurately and efficiently.

[0056] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
