The present invention is described in detail and technical content with reference to the accompanying drawings, wherein:

referring to fig. 1 to 6, an embodiment of a relay device 100 for relaying riding information of a bicycle according to the present invention includes a housing 10 selectively mountable on a grip 31 of a bicycle 30, a first communication unit 11 disposed in the housing 10 and implemented with at least a first communication protocol (e.g., ANT + communication protocol or other suitable wired or wireless communication protocol), an operation interface unit (e.g., an operation stick 12) disposed on the housing 10, a second communication unit 13 disposed in the housing 10 and implemented with at least a second communication protocol (e.g., based on bluetooth communication protocol, such as bluetooth 1.0-3.0 or bluetooth low energy, or other suitable wireless communication protocol), and a signal relay unit 14 disposed in the housing 10.

For example, the housing 10 may be formed with a mounting space 101 and an operation interface fitting hole 102 communicating with the mounting space 101. In addition, the first communication unit 11 can be in information connection with at least one driving state sensing device 32 to receive at least one riding information 321. For example, the driving state sensing device 32 can be a pedal power sensor, a wheel speed sensor, a chest-worn heart rate sensor, or a device applicable to detecting the riding state of the bicycle, but the implementation of the present invention is not limited by this example. Furthermore, the driving state sensing device 32 can use ANT + communication protocol to implement communication, the push relay device 100 can be connected with any driving state sensing device 32 implemented by ANT + communication protocol, and the push relay device 100 can be connected with any driving state sensing device 32 information purchased by the rider previously.

Further, the operation rocker 12 is provided in the operation interface fitting hole 102, and the operation rocker 12 includes an operation portion 121 that protrudes from the operation interface fitting hole 102 and allows being pushed in multiple directions, and a command output portion 123 that connects the operation portion 121 and generates an operation command 122 based on a direction in which the operation portion 121 is pushed.

For example, the operation stick 12 may generate a plurality of the operation commands 122, each of the operation commands 122 is set to correspond to one of the operation postures of the operation portion 121, for example, when the operation portion 121 is operated to swing towards the left, the command output portion 123 outputs the operation command 122. When the operation unit 121 is operated to swing to the right, the instruction output unit 123 outputs another operation instruction 122. Furthermore, the operation instructions 122 are designed to have different numerical codes. In addition, the second communication unit 13 can be paired to connect with the smart device 40, and the second communication unit 13 is in communication with a communication module (such as a bluetooth module or other wireless communication module) of the smart device 40. The smart device 40 is, for example, a smartphone, tablet, wearable device, or other computing device. The implementation of the invention is not limited by the above examples.

As described above, the signal relay unit 14 is connected to the first communication unit 11, the second communication unit 13, and the operation lever 12. The signal relay unit 14 may be implemented by a microcontroller; the signal relay unit 14 is optionally implemented to perform or not perform operational analysis on the ride information 221. The signal relay unit 14 broadcasts the received riding information 221 or the operation command 122 to the intelligent device 40 through the second communication unit 13 in a wireless communication manner, such as a bluetooth communication manner, for the intelligent device 40 to perform operations and then play or display.

Referring to fig. 1 to 6 again, in an embodiment, the push relay device 100 includes a first circuit board 15 disposed on the housing 10 and providing the first communication unit 11, the second communication unit 13, and the signal relay unit 14, and a second circuit board 16 disposed on the housing 10 and providing the operation lever 12 disposed thereon and perpendicular to the first circuit board 15. As a result, the housing 10 is substantially L-shaped, which can increase the stability of the handle 21, and the operation lever 12 can be positioned at a position where the rider can operate without changing the posture when the push relay apparatus 100 is operated. In addition, in an embodiment of the present invention, the implementation can be realized by using at least two circuit board structures, and the volume of the push relay apparatus 100 can be reduced. On the other hand, the housing 10 includes a bearing portion 101, a fixed hook 103 provided on a side of the bearing portion 101, and a flexible connecting portion 104 provided on a side of the bearing portion 101 and capable of being fixed to the fixed hook 103 around the grip portion 31. The supporting portion 10 is used for supporting the above-mentioned components disposed in the housing 10, the fixed hook 103 and the flexible connecting portion 104 are respectively disposed on two opposite sides of the supporting portion 10, the flexible connecting portion 104 can selectively generate a connection relationship with the fixed hook 103, and when the flexible connecting portion 104 is connected to the fixed hook 103, the housing 10 is in a ring shape and can be annularly disposed at the grip 31 of the bicycle 30.

Referring to fig. 1 to 6 again, the push relay device 100 includes an on-off switch 17 configured to be exposed outside the housing 10, and an electric power providing unit 18 disposed in the housing 10 and connected to the on-off switch 17 and electrically connected to the first communication unit 11, the second communication unit 13 and the signal relay unit 14. The on-off switch 17 is electrically connected to the power supply unit 18 and provides manual operation for a rider, the on-off switch 17 outputs a power-on signal or a power-off signal based on an operated state, and the power supply unit 18 performs corresponding work based on the received power-on signal or the received power-off signal. In addition, the power supply unit 18 may include a battery. On the other hand, the broadcasting relay apparatus 100 includes at least one status indicator lamp 19 connected to the signal relay unit 14; the status indicator light 19 is optionally configured to be exposed to the exterior of the housing 10. For example, the signal relay unit 14 may be configured to illuminate the status indicator light 19 when receiving power from the power supply unit 18, so that the rider can know the current status of the push relay 100. In addition, the status indicator light 19 may also be implemented for other purposes, such as indicating other status, information, or other indications of the push relay device 100; the implementation of the invention is not limited by the above examples.

Referring also to fig. 1, in one embodiment, the push relay device 100 optionally includes at least one directional light control 20. The turn signal control part 20 is connected with the signal relay unit 14 to send a turn signal control signal 201 to the intelligent device 40 through the second communication unit 13; the direction light control member 20 is optionally configured to be exposed to the outside of the housing 10. In implementation, the intelligent device 40 is connected to at least one direction light set 33 in a wireless communication manner, such as a bluetooth communication manner, and when the intelligent device 40 receives the direction light control signal 201 from the push relay device 100, the intelligent device sends a control signal to the direction light set 33 to start the direction light set 33. Further, the direction control member 20 has at least two operation modes, each of the operation modes generates a different direction light signal 201, that is, each of the direction light signals 201 includes an instruction for controlling the mode of the direction light set 33. In addition, the direction light signal 201 generated by the direction controller 20 is sent to the direction light set 33 via the first communication unit 11. In summary, the direction light set 33 in the above embodiment may include a plurality of light components, one of the light components may be connected to the intelligent device 40 in a wireless communication manner, such as a bluetooth communication manner, and the other light components may be connected to the other light components in a wired or wireless manner. Since the direction light control 20 is an optional element, the direction light control 20 may not be implemented when implementing the push relay device 100. The implementation of the invention is not limited by the above examples.

In view of the above, referring to fig. 7, an embodiment of the present invention further provides a method 50 for broadcasting bicycle riding information, the method comprising the steps of:

as shown in step 51, providing the aforementioned push relay device 100;

receiving the ride information 321 sent by at least one driving state sensing device 32 by the push relay device 100, as shown in step 52;

sending the ride information 321 to the intelligent device 40 by the push relay device 100 in a wireless communication manner (e.g., bluetooth protocol), as shown in step 53; and

as shown in step 54, the intelligent device 40 calculates and analyzes the ride information 321, and the sound playing device 41 connected to the intelligent device 40 with information is used for playing.

The above steps are further exemplified below. The push relay device 100 is disposed at the grip 31 of the bicycle 30, and at this stage, the push relay device 100 may first complete a pairing (e.g., a pairing of a bluetooth connection) with the smart device 40, for example, the push relay device 100 may communicate with the smart device 40 through the second communication unit 13. Next, in step 52, each driving state sensing device 32 sends out the riding information 321 according to ANT + communication protocol, for example, and the push relay device 100 receives the riding information 321 through the first communication unit 11. In step 53, the signal relay unit 14 in the push relay apparatus 100 acquires the ride information 321 received by the first communication unit 11, and transmits the ride information 321 to the smart device 40 via the second communication unit 13. When the step 54 is performed, the intelligent device 40 calculates and analyzes the ride information 321 by using a pre-loaded mobile Application (APP) or other applications when receiving the ride information 321, and displays the ride information by using a user display interface (GUI) to which the mobile application belongs. In addition, the mobile application program may also convert the result into voice information after operation and analysis, and play the voice information through the voice playing device 41 connected to the intelligent device 40 by wire or wirelessly. In addition, the mobile application can convert the result into the sound information through a pronunciation database built by the mobile application. Further, the sound playing device 41 may be an earphone or a speaker provided in a helmet, and the implementation of the present invention is not limited by the above examples. In addition, the mobile application can upload the calculated and analyzed riding information 321 to the cloud system based on the set time, perform information backup, and provide a record that the rider can review the past riding. As mentioned above, the mobile application can be set to have a plurality of play modes, for example, one of the play modes can be to broadcast each of the ride information 321 in sequence, and the other play mode can be to insert a designated one of the ride information 321.

Referring to fig. 8, in an embodiment, the step 54 includes sub-steps 541: changing the play mode of the ride information 321 with the smart device 40 based on the received operation instructions 122. Further, the mobile application program sets different play modes corresponding to each of the operation instructions 122, and the mobile application program determines the play modes according to the currently received operation instructions. After the push relay device 100 is started, the intelligent device 40 does not obtain the operation command 122, and the mobile application performs voice playing in a preset one of the playing modes, for example, sequentially broadcasts each of the riding messages 321.

Referring to fig. 2 and 9, the push relay device 100 can be mounted on the handle at different positions according to different types of bicycles, and in the case of the bent handle 34 illustrated in fig. 9, the push relay device 100 can be mounted on the brake operating member 35 of the bent handle 34.

In the embodiment of the push relay device, the operation interface unit is illustrated by using the operation joystick 12 as an example, however, the implementation manner of the present invention is not limited by this example. In any of the embodiments based on the above-described push relay device, the operation interface unit may be implemented in other ways instead, such as the operation interface unit 60 shown in fig. 10.

As shown in fig. 10, the operation interface unit 60 includes an operation unit 161 and a command output unit 163. The operation interface unit 60 may be disposed at the operation interface fitting hole 102, and the operation portion 161 may be configured to protrude from the operation interface fitting hole 102 and allow to be operated. The instruction output part 163 is connected with the operation part 161 and generates an operation instruction based on the operation received by the operation part 161; the instruction output unit 163 is, for example, a chip for generating a corresponding operation instruction. In implementation, the operation interface assembly hole 102 may be configured to have a suitable size or shape according to a specific implementation of the operation interface unit 60, and is not limited by the foregoing embodiment or the drawings.

The user can slide up, down, left, and right at different positions or areas on the touch surface of the operation portion 161A, and can be configured to achieve the same or other functions as those of the operation portion 121 of the operation stick 12. The operation unit 161A may accept a click action and generate another function. The instruction output section 163A generates an operation instruction based on the operation received by the operation section 161A.

The manner of scrolling the operation portion 161C in the up-down direction by the user, such as the magnitude or speed of the scrolling width, may be configured to achieve a similar or other function as the operation portion 121 of the aforementioned operation lever 12. The instruction output section 163C generates an operation instruction based on the operation received by the operation section 161C. The operation portion 161C may be configured to roll in the left-right direction, or the operation portion 161C may include a plurality of rollers.

The implementation of the present invention is not limited by the above examples, and the operation interface unit may be implemented in other ways.
