[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0021] The electromagnetic communication wheel hub and vehicle of this application embodiment are described below with reference to the accompanying drawings. Addressing the issues mentioned in the background section regarding the inability to promptly ascertain the wheel hub status and the high cost of specialized equipment required for wheel hub status detection, this application provides an electromagnetic communication wheel hub, comprising a wheel hub body, a wheel hub electromagnetic fixing ring, a vehicle body drive shaft electromagnetic fixing ring, a detection component and a processing component disposed on the wheel hub body. The detection component detects the current connection information of the connection point between the wheel hub body and the vehicle body drive shaft, the current relative displacement data between the wheel hub electromagnetic fixing ring and the vehicle body drive shaft electromagnetic fixing ring, the current electromagnetic force fluctuation state, and / or the current number of rotations of the wheel hub body. The processing component generates the current operating status and current risk status of the electromagnetic communication wheel hub based on the current connection information, current relative displacement data, current electromagnetic force fluctuation state, and / or the current number of rotations. This solves the problems of the inability to promptly ascertain the wheel hub status and the high cost of specialized equipment required for wheel hub status detection. Users can view the wheel hub's operating status in real time and anticipate and manage wheel hub risks.

[0022] Specifically, Figure 1 This is a block diagram of an electromagnetic communication hub provided in an embodiment of this application.

[0023] like Figure 1 As shown, the electromagnetic communication wheel hub 10 includes: a wheel hub body 100, a wheel hub electromagnetic fixing ring 200, a vehicle body drive shaft electromagnetic fixing ring 300, a detection component 400 and a processing component 500 disposed on the wheel hub body 100.

[0024] The detection component 400 is used to detect the current connection information of the connection point between the wheel hub body 100 and the vehicle drive shaft, the current relative displacement data between the wheel hub electromagnetic fixing ring 200 and the vehicle drive shaft electromagnetic fixing ring 300, the current electromagnetic force fluctuation state, and / or the current number of rotations of the wheel hub body 100; the processing component 500 is used to generate the current working state and current risk status of the electromagnetic communication wheel hub 10 based on the current connection information, the current relative displacement data, the current electromagnetic force fluctuation state, and / or the current number of rotations.

[0025] In some embodiments, both the wheel hub electromagnetic retaining ring 200 and the vehicle body drive shaft electromagnetic retaining ring 300 have a sawtooth structure.

[0026] Understandably, the surface structures of the wheel hub electromagnetic retaining ring 200 and the vehicle body drive shaft electromagnetic retaining ring 300 fit together, providing a stable connection and increasing friction.

[0027] Optionally, in some embodiments, the detection component 400 includes: a connection status sensor 401 disposed on the wheel hub body 100, an electromagnet displacement sensor 402 disposed on the wheel hub body 100, a metal fatigue sensor 403 disposed on the wheel hub body 100, and an electromagnet electromagnetic sensor 404 disposed on the wheel hub body 100. The connection status sensor 401 is used to detect the current connection information between the wheel hub body 100 and the vehicle drive shaft connection point; the electromagnet displacement sensor 402 is used to detect the current relative displacement data between the wheel hub electromagnetic retaining ring 200 and the vehicle drive shaft electromagnetic retaining ring 300; the metal fatigue sensor 403 is used to detect the current number of rotations of the wheel hub body 100; and the electromagnet electromagnetic sensor 404 is used to detect the current electromagnetic state and current magnetic fluctuation state between the wheel hub electromagnetic retaining ring 200 and the vehicle drive shaft electromagnetic retaining ring 300.

[0028] Specifically, the detection component 400 includes a connection status sensor 401, an electromagnet displacement sensor 402, a metal fatigue sensor 403, and an electromagnet electromagnetic sensor 404.

[0029] Among them, such as Figure 2 As shown, the connection status sensor 401 is used to detect the current connection information of the connection point between the wheel hub body 100 and the vehicle body drive shaft, including whether the connection point between the wheel hub body 100 and the vehicle body drive shaft is connected or not. When the connection point between the wheel hub body 100 and the vehicle body drive shaft is not connected, the processing component 500 receives the disconnection information sent by the connection status sensor 401 and sends a reminder message to the user to reconnect.

[0030] The electromagnetic displacement sensor 402 is used to detect whether the current relative displacement data between the wheel hub electromagnetic fixing ring 200 and the vehicle body drive shaft electromagnetic fixing ring 300 is equal to 0. If the current relative displacement data is not equal to 0, the wheel hub body 100 only receives intelligent driving instructions issued by the vehicle body computer to avoid the risk of wheel hub falling off due to human error.

[0031] The metal fatigue sensor 403 is used to detect the current number of rotations of the wheel hub body 100. According to the limit of rotations = the limit number of rotations when the relative displacement caused by the magnetic force released by the electromagnets on both sides is always 0 minus N, a variable can be set according to different materials to provide a safe range before reaching the limit.

[0032] Electromagnetic sensor 404 is used to detect the current electromagnetic state and magnetic fluctuation state between the wheel hub electromagnetic fixing ring 200 and the vehicle drive shaft electromagnetic fixing ring 300. When the wheel hub body 100 and the vehicle drive shaft are connected and the relative displacement is 0, the magnetic fluctuation state is detected. If fluctuation continues but the relative displacement remains 0, intelligent driving will not force a pullover; instead, a warning will be displayed on the vehicle screen and mobile phone, prompting a vehicle inspection. The standard for magnetic fluctuation is that it does not coincide with the initial stability line, being located above or below it. The standard for judging electromagnetic stability is the data generated between the wheel hub electromagnetic fixing ring 200 and the vehicle drive shaft electromagnetic fixing ring 300 after connection. In this state, both the wheel hub electromagnetic fixing ring 200 and the vehicle drive shaft electromagnetic fixing ring 300 simultaneously provide their output and received signals for cross-comparison.

[0033] Optionally, in some embodiments, the processing component 500 includes: a connection state processor 501 disposed on the hub body 100, an electromagnet displacement processor 502 disposed on the hub body 100, a metal fatigue processor 503 disposed on the hub body 100, and an electromagnet electromagnetic processor 504 disposed on the hub body 100. The connection status processor 501 receives the current connection information detected by the connection status sensor 401 and obtains the current connection status of the connection point between the wheel hub body 100 and the vehicle body drive shaft based on the current connection information; the electromagnet displacement processor 502 receives the current relative displacement data detected by the electromagnet displacement sensor 402 and controls the electromagnetic communication wheel hub to only receive control commands from the vehicle body computer when the current relative displacement data does not meet the preset displacement conditions; the metal fatigue processor 503 receives the current number of rotations detected by the metal fatigue sensor 403 and obtains the fatigue data of the electromagnetic communication wheel hub based on the current number of rotations and the preset limit number of rotations; the electromagnet electromagnetic processor 504 receives the current electromagnetic magnetic force fluctuation state sent by the electromagnet electromagnetic sensor 404 and generates preset reminder information when the current electromagnetic magnetic force fluctuation state meets the preset fluctuation state and the current relative displacement data meets the preset displacement conditions; and the control unit generates the current working status and current risk status based on the current connection status, current relative displacement data, fatigue data, and / or preset reminder information.

[0034] Specifically, the connection status processor 501 is used to receive and process the current connection information detected by the connection status sensor 401.

[0035] The electromagnet displacement processor 502 is used to receive and process the current relative displacement data detected by the electromagnet displacement sensor 402. When the current relative displacement data does not meet the preset displacement conditions (i.e., the relative displacement data is not equal to 0), the control electromagnetic communication wheel hub only receives the control commands from the vehicle body computer.

[0036] The metal fatigue processor 503 is used to receive the current number of rotations detected by the metal fatigue sensor 403, and obtain the fatigue data of the electromagnetic communication hub based on the current number of rotations and the preset limit number of rotations, and process the life determination of the hub electromagnetic fixing ring 200.

[0037] The electromagnet processor 504 is used to receive the current electromagnetic force fluctuation state sent by the electromagnet sensor 404, and when the current electromagnetic force fluctuation state meets the preset fluctuation state (i.e., the electromagnetic force fluctuation state is a continuous fluctuation state) and the current relative displacement data meets the preset displacement condition (i.e., when the relative displacement data is 0), it generates preset reminder information, such as parking inspection information, and sends it to the vehicle screen and the user's mobile phone to remind the user to check the vehicle condition.

[0038] The control unit generates the current working status and current risk status of the wheel hub based on the current connection status, current relative displacement data, fatigue data, and preset reminder information.

[0039] It should be understood that the control unit combines the connection information of the wheel hub body 100 and the connection point of the vehicle drive shaft, the current relative displacement data between the wheel hub electromagnetic fixing ring 200 and the vehicle drive shaft electromagnetic fixing ring 300, the fatigue data of the electromagnetic communication wheel hub, and the preset reminder information to generate the current working status and current risk status of the wheel hub. For example, if the wheel hub is deformed or cracked, resulting in tire leakage, vehicle vibration, or other risk conditions, the user will be reminded to have it inspected.

[0040] Alternatively, in some embodiments, such as Figure 2 As shown, the processing component 500 also includes a hub electromagnetic retaining ring battery processor 505, used to generate a power supply command when the vehicle battery power is less than a preset power.

[0041] Understandably, the wheel hub electromagnetic retaining ring battery processor 505 is used to receive emergency power from the vehicle body battery. If there is no power input to the vehicle body, the magnetic force of the wheel hub and the vehicle body drive shaft electromagnetic retaining ring 300 will disappear. When the vehicle body battery power is less than the preset power, the wheel hub electromagnetic retaining ring battery processor 505 generates a power supply command to maintain the magnetic force and start the automatic driving system to pull over to the side of the road.

[0042] Alternatively, in some embodiments, such as Figure 2 As shown, the processing component 500 also includes a power supply unit 506, which supplies power to the wheel hub electromagnetic retaining ring 200 and the vehicle body drive shaft electromagnetic retaining ring 300 based on a power supply command.

[0043] In some embodiments, the power supply unit 506 is a hub electromagnetic retaining ring battery.

[0044] Understandably, the wheel hub electromagnetic retaining ring battery supplies power to the wheel hub electromagnetic retaining ring 200 and the vehicle body drive shaft electromagnetic retaining ring 300 based on the power supply command generated by the wheel hub electromagnetic retaining ring battery processor 505.

[0045] Optionally, in some embodiments, the electromagnetic communication wheel hub 10 described above further includes a cutting component 600, which is used to generate induced electrical energy by cutting the magnetic field lines located on the vehicle body and to store the induced electrical energy in the wheel hub electromagnetic retaining ring battery. In some embodiments, the cutting component is a metal sheet.

[0046] It should be understood that the metal sheet is used to cut the magnetic field lines of the vehicle body to generate induced electrical energy, and the induced electrical energy is stored in the wheel hub electromagnetic retaining ring battery.

[0047] The electromagnetic communication wheel hub proposed in this application comprises a wheel hub body, a wheel hub electromagnetic fixing ring, a vehicle body drive shaft electromagnetic fixing ring, a detection component and a processing component mounted on the wheel hub body. The detection component detects the current connection information between the wheel hub body and the vehicle body drive shaft, the current relative displacement data between the wheel hub electromagnetic fixing ring and the vehicle body drive shaft electromagnetic fixing ring, the current electromagnetic force fluctuation state, and / or the current number of rotations of the wheel hub body. The processing component generates the current operating status and current risk status of the electromagnetic communication wheel hub based on the current connection information, current relative displacement data, current electromagnetic force fluctuation state, and / or current number of rotations. This solves the problems of the wheel hub status not being known in a timely manner and the need for specialized equipment for wheel hub status detection, which is expensive. Users can view the wheel hub's operating status in real time and predict and handle potential risks.

[0048] This application also provides a vehicle that includes the aforementioned electromagnetic communication hub.

[0049] This solves the problems of not being able to know the wheel hub status in a timely manner, and the need for professional equipment and high costs to detect wheel hub status. Users can view the working status of the wheel hub in real time and predict and deal with the risk of wheel hub failure.
