The two assembly structures 3116, 3117 are respectively a through hole and a screw hole, and the two assembly structures 3116, 3117 are located on opposite sides of the notch 3115.

The collar body 311 abuts against the second end surface 114 of the grip portion 11 of the grip cover 10, and the two second assembly protrusions 13 of the grip cover 10 are respectively located in the two assembly grooves 3112 of the collar body 311, and the clearance groove 3113 of the collar body 311 is aligned with the clearance groove 115 of the grip portion 11. The locking member 312 is, for example, a screw. The locking member 312 passes through the assembly structure 3116 and is locked to the assembly structure 3117, so that the collar body 311 is in a tightened state to fix the other end of the grip cover 10 to the handlebar 2 of the bicycle.

The transmitter 32 includes a housing 321, a circuit board 322, an antenna 323, a switch 324 and a trigger 325. In addition, the transmitter 32 may further include two screws 326, a light emitting element 327 and two batteries 328, 329.

The housing 321 is made of, for example, plastic. The housing 321 includes a seat 3211 and a cover 3212. The seat 3211 may have two ends 32118, 32119 and an assembly flange 32111, the two ends 32118, 32119 are opposite to each other, and the assembly flange 32111 is located at the end 32118. The seat 3211 is inserted into the collar body 311 along the axial direction of the collar body 311, and the assembly flange 32111 of the seat 3211 abuts against a side of the inner flange 3114 of the collar body 311 away from the grip cover 10. The two screws 326 pass through the inner flange 3114 of the collar body 311 and are locked to the assembly flange 32111 of the seat body 3211, so that the seat body 3211 is fixed on the inner flange 3114 of the collar body 311. The seat body 3211 is inserted into the handlebar 2 from an opening 3 on the axis of the handlebar 2, and a part of the seat body 3211 is located in the handlebar 2.

It should be noted that the seat 3211 is not limited to being fixed to the collar body 311 by screws 326. In other embodiments, the seat can be integrally connected to the collar body, and the screws can be omitted.

In this embodiment, the cover 3212 may have two opposite ends 32122 and 32123. The cover 3212 is located in the handlebar 2, and the end 32122 of the cover 3212 is pivoted to the end 32119 of the seat 3211. The cover 3212 may also have a fixing protrusion 32121, and the fixing protrusion 32121 is located at the end 32123. The seat 3211 may also have a fixing groove 32112. The fixing protrusion 32121 is fixed to the fixing groove 32112, so that the cover 3212 is positioned in a closed position.

The circuit board 322 is located in the base 3211. The antenna 323 is arranged on the surface 3221 of the circuit board 322, and the antenna 323 is completely located outside the handlebar 2. In other words, the orthographic projection of the antenna 323 along the radial direction D of the handlebar 2 cannot overlap the handlebar 2. In this way, the signal receiving and transmitting quality of the antenna 323 can be ensured. It should be noted that the antenna 323 is not limited to being completely located outside the handlebar 2. In the case where the signal receiving and transmitting quality of the antenna can be satisfied, the antenna of other embodiments may be partially located outside the handlebar or completely located inside the handlebar. In other words, the orthographic projection of the antenna along the radial direction of the handlebar may partially or completely overlap the handlebar.

In this embodiment, the base 3211 may further have an end surface 32113, a first through hole 32114 and a second through hole 32115. The end surface 32113 is located at the end 32118 and is exposed outside the handlebar 2 and the collar body 311. The first through hole 32114 and the second through hole 32115 are both located on the end surface 32113. The switch 324 and the light-emitting element 327 are respectively disposed on two opposite surfaces 3222 and 3221 of the circuit board 322. The switch 324 and the light-emitting element 327 correspond to the first through hole 32114 and the second through hole 32115 of the base 3211, respectively. The trigger 325 passes through the first through hole 32114, and the trigger 325 is used to trigger the switch 324, so that the antenna 323 sends a wireless signal to an external electronic device (not shown). The wireless signal is, for example, a pairing signal. After the trigger 325 triggers the switch 324, the antenna 323 sends the pairing signal to the external electronic device, and establishes wireless communication between the wireless transmission device 30 and the external electronic device. The light-emitting element 327 is, for example, an LED. After the trigger 325 triggers the switch 324, the light-emitting element 327 lights up and the light it emits is transmitted from the second through hole 32115 for personnel identification.

In this embodiment, the light emitted by the light emitting element 327 is directly transmitted through the second through hole 32115, but the present invention is not limited thereto. In other embodiments, a light guide member may be disposed in the second through hole to guide the light emitted by the light emitting element to the outside.

Furthermore, the positions of the switch 324 and the light emitting element 327 are not intended to limit the present invention. In other embodiments, the switch and the light emitting element may be disposed on the same surface of the circuit board.

In addition, the switch 324, the trigger 325 and the light emitting element 327 of the transmitter 32 are optional components. In other embodiments, the transmitter may not have a switch, a trigger and a light emitting element, and the aforementioned components may be replaced on an external electronic device, and the wireless communication between the wireless transmission device and the external electronic device can also be realized.

The base 3211 may also have two battery slots 32120, and the cover 3212 has two assembly slots 32124 and 32125 of different shapes. The two batteries 328 and 329 are, for example, button batteries of the same model. The shape of the assembly slot 32124 of the cover 3212 only matches the negative end of the button battery, and the shape of the assembly slot 32125 of the cover 3212 only matches the positive end of the button battery. The positive end of the battery 328 is installed in one of the battery slots 32120 of the base 3211, and the negative end of the battery 328 is installed in the assembly slot 32124 of the cover 3212. The negative end of the battery 329 is mounted in another battery slot 32120 of the base 3211, and the positive end of the battery 329 is mounted in the assembly slot 32125 of the cover 3212. The batteries 328 and 329 are shielded by the cover 3212 and the base 3211. The distance between the battery 328 and the inner convex edge 3114 of the tie ring body 311 is different from the distance between the battery 329 and the inner convex edge 3114 of the tie ring body 311. The two batteries 328 and 329 are electrically connected to the circuit board 322 and are used to provide power required by the antenna 323, the light emitting element 327 and the switch 324.

In this embodiment, the two assembly grooves 32124 and 32125 of the cover 3212 with different shapes are respectively matched to the negative terminal and the positive terminal of the button battery, so as to provide a foolproof function to ensure that the cover 3212 can be closed only when the batteries 328 and 329 are correctly installed, so that the fixing protrusion 32121 is fixed to the fixing groove 32112. It should be noted that the two assembly grooves 32124 and 32125 of the cover 3212 are not limited to different shapes. In other embodiments, the two assembly grooves of the cover can be the same shape.

It should be noted that the number of batteries 328, 329 is not intended to limit the present invention. In other embodiments, the wireless transmission device may have only one battery.

On the other hand, the light emitted by the light emitting element 327 is not limited to being used by personnel to identify that the switch 324 is triggered by the trigger element 325 to generate a pairing signal. In other embodiments, the light emitted by the light emitting element can be used by personnel to identify the battery power. For example, different light signals can be used to display the amount of remaining battery power, such as a green light indicating that the battery power is sufficient, and a red light indicating that the battery power is about to be insufficient.

In this embodiment, the base 3211 may also have a waterproof ridge 32116, and the waterproof ridge 32116 is located between the cover 3212 and the inner ridge 3114 of the collar body 311. The wireless transmission device 30 may also include a waterproof cover 33. The waterproof cover 33 is mounted on the housing 321 and located in the handlebar 2, and the waterproof cover 33 abuts against the waterproof ridge 32116 to provide a waterproof effect.

It should be noted that waterproof cover 33 and waterproof flange 32116 are selected elements and structures. In other embodiments, the bicycle assembly may not have a waterproof cover, and the seat may not have a waterproof flange.

In this embodiment, the waterproof cover 33 may have a through hole 331, and the base 3211 may also have an opening 32117. The opening 32117 of the base 3211 is connected to the through hole 331 of the waterproof cover 33. The bicycle assembly 1 may also include an electrical connector 60 and a cable 70. The electrical connector 60 passes through the opening 32117 of the base 3211 and the through hole 331 of the waterproof cover 33. The electrical connector 60 may have two opposite connectors 61 and 62. The connector 61 is plugged into the connector 3223 on the circuit board 322, and the connector 62 is located in the handlebar 2. The cable 70 may have two opposite connectors 71 and 72. The connector 71 of the cable 70 is located in the handlebar 2 and assembled to the connector 62 of the electrical connector 60. The cable 70 passes through the opening 3 of the handlebar 2, passes through the clearance groove 3113, the clearance groove 115 and the clearance groove 2113, and passes through the housing 221 and the box body 2221. The connector 72 of the cable 70 is plugged into the connector 22222 on the circuit board 2222 (as shown in FIG. 4 ).

In this embodiment, the circuit board 2222 of the control device 20 is signal-connected to the circuit board 322 of the wireless transmission device 30. The aforementioned signal connection means that the signal can be transmitted between the circuit board 2222 of the control device 20 and the circuit board 322 of the wireless transmission device 30 in a wired or wireless manner. In this embodiment, the circuit board 2222 of the control device 20 and the circuit board 322 of the wireless transmission device 30 are signal-connected by wire through the cable 70 and the electrical connector 60. In this way, the battery 328 of the wireless transmission device 30 can provide the required power to the control device 20, and the signal generated when one of the two switches 2223 of the control device 20 is triggered can be transmitted to the wireless transmission device 30, and then the antenna 323 of the wireless transmission device 30 transmits the signal to the external electronic device to control the external electronic device.

For example, the external electronic device is a transmission, and the two switches 2223 of the control device 20 are a shift switch and a shift-down switch. When the rider presses one of the triggers 223 to trigger the shift switch, a shift signal is generated. The shift signal is transmitted to the circuit board 322 of the wireless transmission device 30 through the cable 70 and the electrical connector 60, and the antenna 323 then sends the shift signal to the transmission wirelessly, so that the transmission shifts. Similarly, the shift-down signal generated after the shift-down switch is triggered is also transmitted through the same process, so it is not repeated.

In this embodiment, the external electronic device is a transmission, but is not limited thereto. In other embodiments, the external electronic device may be a shock absorber, a seat tube, or a turn signal, and the two switches of the control device may be a switch for increasing and decreasing the stiffness of the shock absorber, a switch for raising and lowering the seat tube, or a switch for turning the left turn signal and the right turn signal, respectively.

It should be noted that batteries 328 and 329 are optional components. In other embodiments, the wireless transmission device may not have a battery, and the power required by the wireless transmission device may be provided by other means. For example, a battery is added to the control device, and the power of the battery can be provided to the wireless transmission device via a cable and an electrical connector.

It should be noted that the electrical connector 60 is an optional component. In other embodiments, the bicycle assembly may not have an electrical connector, and the cable may be directly connected to the connector on the circuit board of the wireless transmission device.

In this embodiment, the two first assembly protrusions 12 of the grip cover 10 are respectively located in the two assembly grooves 2112 of the collar body 211, and the two second assembly protrusions 13 of the grip cover 10 are respectively located in the two assembly grooves 3112 of the collar body 311, so that the grip cover 10 can be prevented from unexpectedly rotating relative to the handlebar 2, thereby ensuring that the grip cover will not twist the cable 70.

It should be noted that the number of the first assembly protrusions 12 and the number of the second assembly protrusions 13 of the grip cover 10 are not intended to limit the present invention. In other embodiments, the grip cover may have only one first assembly protrusion and one second assembly protrusion, or the grip cover may have no first assembly protrusion and no second assembly protrusion.

On the other hand, the cable 70 is also an optional component. In other embodiments, the bicycle assembly may not have a cable, and the wireless transmission device and the control device may be connected by wireless signal. In such a configuration, the structure through which the aforementioned cable passes (such as the yield groove of the two-beam ring body and the yield groove of the grip portion of the grip cover) and the first assembly protrusion and the second assembly protrusion of the grip cover may be omitted.

In this embodiment, the two ends of the grip cover 10 are fixed to the handlebar 2 through the first fastener 21 of the control device 20 and the second fastener 31 of the wireless transmission device 30, and the controller 22 of the control device 20 is installed on the handlebar 2 through the first fastener 21, and the transmitter 32 of the wireless transmission device 30 is installed on the handlebar 2 through the second fastener 31. In this arrangement, the first fastener 21 can simultaneously fix the grip cover 10 and allow the controller 22 to be installed on the handlebar 2, and the second fastener 31 can simultaneously fix the grip cover 10 and allow the transmitter 32 to be installed on the handlebar 2. Therefore, the number of fasteners installed on the handlebar 2 can be reduced, thereby improving the aesthetics of the appearance of the bicycle.

It should be noted that the structural form of the first fastener 21 and the second fastener 31 is not intended to limit the present invention. As long as the first fastener and the second fastener can fix the two opposite ends of the grip cover to the handlebar and respectively provide connection for the control device and the wireless transmission device, the first fastener and the second fastener can be of any possible structural form.

Next, please refer to Figures 8 and 9. Figure 8 is a three-dimensional schematic diagram of the wireless transmission device and the handlebar according to the second embodiment of the present invention. Figure 9 is an exploded schematic diagram of Figure 8.

The seat 3211a may have two ends 32118a, 32119a and an assembly flange 32111a, the two ends 32118a, 32119a are opposite to each other, and the assembly flange 32111a is located at the end 32118a. The seat 3211a is penetrated in the collar body 311a along the axial direction of the collar body 311a, and the assembly flange 32111a of the seat 3211a abuts against a side of the inner flange 3114a of the collar body 311a away from the handlebar 2'. The two screws 326a pass through the inner flange 3114a of the collar body 311a and are locked to the assembly flange 32111a of the seat body 3211a, so that the seat body 3211a is fixed on the inner flange 3114a of the collar body 311a. The seat body 3211a is inserted into the handlebar 2' from an opening 3' upward from the axis of the handlebar 2', and a part of it is located in the handlebar 2'.

It should be noted that the seat 3211a is not limited to being fixed to the collar body 311a by screws 326a. In other embodiments, the seat can be integrally connected to the collar body, and the screws can be omitted.

In this embodiment, the cover 3212a may have two opposite ends 32122a and 32123a. The cover 3212 is located in the handlebar 2, and the end 32122a of the cover 3212a is pivoted to the end 32119a of the seat 3211a. The cover 3212a may also have a fixing convex block 32121a, and the fixing convex block 32121a is located at the end 32123a. The seat 3211a may also have a fixing groove 32112a. The fixing convex block 32121a is fixed to the fixing groove 32112a, so that the cover 3212a is positioned in a closed position.

In other words, the orthographic projection of the antenna 323a along the radial direction D of the handlebar 2' cannot overlap with the handlebar 2'. In this way, the signal reception and transmission quality of the antenna 323a can be ensured. It should be noted that the antenna 323a is not limited to being completely located outside the handlebar 2'. In the case where the signal reception and transmission quality of the antenna can be satisfied, the antenna of other embodiments may be partially located outside the handlebar, or completely located inside the handlebar. In other words, the orthographic projection of the antenna along the radial direction of the handlebar may partially or completely overlap with the handlebar.

In this embodiment, the base 3211a may also have an end surface 32113a, a first through hole 32114a and a second through hole 32115a. The end surface 32113a is located at the end 32118a and is exposed outside the handlebar 2' and the ring body 311a. The first through hole 32114a and the second through hole 32115a are both located on the end surface 32113a. The switch 324a and the light-emitting element 327a are respectively disposed on two opposite surfaces 3222a and 3221a of the circuit board 322a. The switch 324a and the light-emitting element 327a correspond to the first through hole 32114a and the second through hole 32115a of the base 3211a, respectively. The trigger 325a passes through the first through hole 32114a, and the trigger 325a is used to trigger the switch 324a, so that the antenna 323a sends a wireless signal to an external electronic device (not shown). The wireless signal is, for example, a pairing signal, and the external electronic device is, for example, a gear shifter, a shock absorber, or a seat tube. After the trigger 325a triggers the switch 324a, the antenna 323a sends the pairing signal to the external electronic device, and establishes wireless communication between the wireless transmission device 30a and the external electronic device. The light-emitting element 327a is, for example, an LED. After the trigger 325a triggers the switch 324a, the light-emitting element 327a lights up and the light it emits is transmitted from the second through hole 32115a for personnel identification.

In this embodiment, the light emitted by the light emitting element 327a is directly transmitted from the second through hole 32115a, but the present invention is not limited thereto. In other embodiments, a light guide member may be disposed in the second through hole to guide the light emitted by the light emitting element to the outside.

Furthermore, the positions of the switch 324a and the light emitting element 327a are not intended to limit the present invention. In other embodiments, the switch and the light emitting element may be disposed on the same surface of the circuit board.

In addition, the switch 324a, trigger 325a and light emitting element 327 of the transmitter 32a are optional components. In other embodiments, the transmitter may not have a switch, a trigger and a light emitting element, and the aforementioned components may be replaced on an external electronic device, and the wireless communication between the wireless transmission device and the external electronic device can also be realized.

The base 3211 may also have two battery slots 32120a. The two batteries 328a and 329a are respectively installed in the two battery slots 32120a of the base 3211a and are shielded by the cover 3212a and the base 3211a. The distance between the battery 328a and the inner convex edge 3114a of the ring body 311a is different from the distance between the battery 329a and the inner convex edge 3114a of the ring body 311a. The two batteries 328a and 329a are electrically connected to the circuit board 322a and are used to provide the power required by the antenna 323a, the light-emitting element 327a and the switch 324a. It should be noted that the number of batteries 328a and 329a is not used to limit the present invention. In other embodiments, the wireless transmission device may have only one battery.

In this embodiment, the base 3211a may also have a waterproof ridge 32116a, and the waterproof ridge 32116a is located between the cover 3212a and the inner ridge 3114a of the collar body 311a. The wireless transmission device 30a may also include a waterproof cover 33a. The waterproof cover 33a is sleeved on the housing 321a and located in the handlebar 2, and the waterproof cover 33a abuts against the waterproof ridge 32116a to provide a waterproof effect.

It should be noted that waterproof cover 33a and waterproof flange 32116a are selected elements and structures. In other embodiments, the bicycle assembly may not have a waterproof cover, and the seat may not have a waterproof flange.

In this embodiment, the waterproof cover 33a may have a through hole 331a, and the base 3211a may also have an opening 32117a. The opening 32117a of the base 3211a is connected to the through hole 331a of the waterproof cover 33a. The through hole 331a of the waterproof cover 33a and the opening 32117a of the base 3211a are used for a cable 70a to pass through. Specifically, one end of the cable 70a is located in the handlebar 2', and passes through the through hole 331a of the waterproof cover 33a and the opening 32117a of the base 3211a to be assembled to the connector 3223a on the circuit board 322a. The cable 70a passes through the axial opening 3' of the handlebar 2', the gap G between the handlebar 2' and the inner flange 3114a, one of the clearance holes 3115a and one of the gaps 3120a (as shown in Figure 9), and extends along the outer surface of the handlebar 2'. The other end of the cable 70a is used to connect to a control device (not shown). The control device is, for example, a device for controlling the shifting of a transmission, a device for adjusting the hardness of a shock absorber, or a device for adjusting the height of a seat tube. When the rider operates the control device, a signal is generated. This signal is transmitted to the circuit board 322a of the wireless transmission device 30a via the cable 70a, and the antenna 323a then sends the shifting signal to the external electronic device wirelessly to control the external electronic device.

In this embodiment, the protruding structures 3116a of the tie ring body 311a and the handlebar 2' are wound with a strap (not shown) to strengthen the fixing force of the tie ring body 311a to the handlebar 2'. It should be noted that the protruding structures 3116a of the tie ring body 311a are optional structures. In other embodiments, the tie ring body may not have these protruding structures.

In the present embodiment, the clearance hole 3115a of the tie ring body 311a allows the cable 70a to pass out of the tie ring body 311a and be arranged along the outer surface of the handlebar 2’. However, the cable 70a is not limited to passing out from the clearance hole 3115a of the tie ring body 311a. For example, please refer to Figure 13, which is a cross-sectional schematic diagram of another arrangement of the cable connected to the wireless transmission device of Figure 12. The cable 70a does not pass out from the clearance hole 3115a of the tie ring body 311a, but extends from the inside of the handlebar 2’ and passes out from other parts of the handlebar 2’. In this way, the structural configuration of the clearance hole 3115a can be omitted in the tie ring body 311a.

According to the bicycle assembly, wireless transmission device and control device disclosed in the above embodiments, the two ends of the grip cover are fixed to the handlebars through the first fastener of the control device and the second fastener of the wireless transmission device, and the controller of the control device is installed on the handlebars through the first fastener, and the transmitter of the wireless transmission device is installed on the handlebars through the second fastener. This configuration allows the first fastener to simultaneously fix the grip cover and allow the controller to be installed on the handlebars, and the second fastener to simultaneously fix the grip cover and allow the transmitter to be installed on the handlebars.
