[0026] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] One embodiment of this utility model provides a bicycle stem for connecting the bicycle's front fork, left handlebar 210, and right handlebar 220; as shown... Figures 1 to 4As shown, the bicycle stem includes a stem body 110, a cover 120, a power supply unit 130, a function control unit, and a display unit 150. The upper end of the stem body 110 has a storage compartment 111 with an open upper end. The cover 120 is detachably or fixedly mounted on the stem and closes the opening of the storage compartment 111. Both the power supply unit 130 and the function control unit are located within the storage compartment 111 and can be fixed therewith using screws or adhesive. The display unit 150 is mounted on the cover 120. The power supply unit 130 is electrically connected to the function control unit and the display unit 150, providing them with power during operation. The function control unit and the display unit 150 are connected by a signal connection for data interaction.

[0028] The bicycle stem provided in this embodiment integrates an intelligent instrument consisting of a power supply unit 130, a function control unit, and a display unit 150 onto the bicycle stem, making the intelligent instrument and the bicycle stem an integral structure rather than an additional component. Compared with the prior art, there is no problem of the independent device occupying the handlebar space and obstructing the operation, nor is there any risk of the independent device falling and being damaged, resulting in a better user experience.

[0029] In the optional implementation of this embodiment, such as Figures 1 to 4 As shown, the lower end of the stem body 110 is provided with a first connecting hole 112, and the left and right ends of the stem body 110 are respectively provided with a second connecting hole 113 and a third connecting hole 114; the bicycle stem also includes a vertical tube, a left handlebar 210 and a right handlebar 220; the upper end of the vertical tube is inserted into the first connecting hole 112 and fixed by screws or other structures, and the lower end of the vertical tube is connected to the front fork of the bicycle; the handlebar tube of the left handlebar 210 is inserted into the second connecting hole 113 and fixed by screws or other structures, and the handlebar tube of the right handlebar 220 is inserted into the third connecting hole 114 and fixed by screws or other structures.

[0030] In an optional implementation of this embodiment, the functional control unit includes an information acquisition module, a data processing module, and a communication module. The communication module is used for electrical connection with external devices, which can be any one or more of a heart rate monitor, power meter, and cadence meter. The communication module can be a 4G module or a Bluetooth module. The information acquisition module is signal-connected to the communication module; the information acquisition module is used to collect cycling environment data and vehicle status data, and data from external devices is transmitted to the information acquisition module via the communication module. The information acquisition module is also signal-connected to the data processing module; the information collected by the data acquisition module is fed back to the data processing module, which calculates and analyzes the collected data, and finally displays it externally through the display unit 150.

[0031] Optionally, in this embodiment, the information acquisition module includes at least one of a Beidou positioning unit, a GPS (Global Positioning System) positioning unit, an LBS (Location Based Services) base station positioning unit, and a Wi-Fi positioning unit to acquire the bicycle's location, the rider's riding speed, and the bicycle's riding trajectory. After subsequent processing, the aforementioned location, speed, and trajectory data can be displayed intuitively through the display unit 150, making it convenient for the rider to view the riding status in real time. The data processing module can be a core component with data processing capabilities, such as an MCU (Microcontroller Unit) or a CPU (Central Processing Unit). Its core function is to calculate and analyze the various raw data acquired by the information acquisition module. For example, based on the displacement change and corresponding time difference acquired by the information acquisition module, the real-time cycling speed can be calculated. If the information acquisition module is connected to an external power meter (such as a peripheral device connected via a communication module), it can combine the acquired power information with the cycling time to calculate the calorie consumption during the cycling process. In addition, if the information acquisition module simultaneously acquires the cyclist's heart rate data (such as by connecting a heart rate belt), the data processing module can also perform exercise intensity analysis (such as determining the exercise zone of the heart rate). At the same time, based on the location information acquired by the positioning unit, it can run a navigation path planning algorithm to generate a cycling navigation route.

[0032] In this embodiment, the data processing module, the communication module, and the positioning unit can be integrated on the same circuit board 141.

[0033] Optional, such as Figures 1 to 4 As shown, the information acquisition module also includes a front camera 142 and a rear camera 143, which are powered by a power supply unit 130. The front camera 142 is mounted on the cover 120, and the rear camera 143 is mounted inside the storage compartment 111. The front camera 142 is positioned facing the rider, and the rear camera 143 is positioned facing the front of the bicycle.

[0034] In this embodiment, a driving recorder function can be achieved by setting a front camera 142 and a rear camera 143. The front and rear cameras 142 and 143 can simultaneously record the road conditions ahead and the situation of vehicles approaching from behind. If an accident such as a collision or scrape occurs during riding, video evidence can be preserved to facilitate the determination of responsibility. Compared with traditional external driving recorders, the camera integrated in the handlebar holder compartment 111 is more concealed, not easy to be damaged or stolen, and does not require additional power supply, simplifying the usage process.

[0035] Optionally, in this embodiment, the information acquisition module also includes an acceleration sensor integrated on the circuit board 141, which is used to detect bicycle vibration, tipping, collision, and the slope of the ride.

[0036] Optional, such as Figure 1 As shown, a speaker 160 is also provided in the storage compartment 111. The speaker 160 is signal-connected to the function control unit and electrically connected to the power supply unit 130. The speaker 160 is used to receive the instructions of the function control unit and issue voice prompts.

[0037] By setting up a speaker 160, the human-computer interaction can be enriched. Riders can obtain key information (such as "low battery", "turn ahead", "collision detected") through voice prompts without having to look down at the display unit 150, thus improving cycling focus and safety. Compared with traditional devices that rely solely on screen displays, voice prompts are more intuitive and are especially suitable for information transmission in complex road conditions.

[0038] Optionally, in this embodiment, the display unit 150 includes a display screen and operation buttons; the display screen is embedded in the outer surface of the cover 120; and the operation buttons are located on one side of the display screen for receiving user operation control.

[0039] The embedded display screen design avoids scratches or collisions to the protruding structure, while also enhancing the overall aesthetics of the stem body 110. The operation buttons are located close to the display screen, which conforms to user operating habits. Riders can quickly switch pages, start and stop functions (such as starting the riding recorder), and set parameters (such as adjusting the screen brightness) without complicated steps. Compared with the scattered operation of traditional independent devices, the integrated display and control components are simpler and improve the user experience.

[0040] Optionally, the power supply unit 130 is a lithium battery; a charging interface is provided on the inner wall of the storage compartment 111 at the position corresponding to the lithium battery, and the charging interface passes through the side wall of the stem body 110 and is electrically connected to the lithium battery. Optionally, the charging interface can be a Type-C interface.

[0041] Lithium batteries have the advantages of high energy density and lightweight design, which are suitable for the weight and range requirements of bicycles. The charging port is designed to run through the side wall of the stem, so that the external charger can be connected for charging without removing the cover of the 120 or lithium battery. This simplifies the range maintenance process, avoids component damage caused by frequent disassembly and assembly, and improves charging convenience, making it especially suitable for outdoor cycling scenarios.

[0042] Another embodiment of the present invention provides a bicycle, including the bicycle stem of any of the above embodiments.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
