Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0023] It should be noted that like reference numerals and letters refer to like items throughout the several views, and once an item is defined in one view, it should not require further defining and explaining in the subsequent views.

[0024] Some embodiments of the present application will be described in detail with reference to the drawings, which are provided for the purpose of illustration only and should not be construed as limiting the present application. The following embodiments and features described herein can be combined with each other, if not mutually exclusive.

[0025] Please refer to Figure 1 , Figure 2 and Figure 3 , the two-wheeled vehicle 100 provided by the embodiments of the present application includes a frame 11, a suspension system 12, a walking system 13, a steering assembly 14 and a display instrument 15. The frame 11 includes a front frame and a rear frame, and a driving area for sitting is provided between the front frame and the rear frame of the frame 11. The suspension system 12 is connected to the frame 11. The walking system 13 is connected to the lower part of the frame 11 through the suspension system 12, wherein the walking system 13 can include front wheels 131 and rear wheels 132, the front wheels 131 and the rear wheels 132 are arranged below the frame 11 through the suspension system 12, and the front wheels 131 are arranged below the front frame of the frame 11, and the rear wheels 132 are arranged below the rear frame of the frame 11. The steering assembly 14 is connected with the walking system 13, and the steering assembly 14 is used for controlling the direction of movement of the walking system 13. The display instrument 15 is arranged on the front frame of the frame 11 to facilitate the user to view.

[0026] The display instrument 15 includes a display screen 151, a mounting shell 152, a circuit board 153 and an NFC coil 154. The display screen 151 is used to display the information of the two-wheeled vehicle 100, the mounting shell 152 forms a mounting space, and the display screen 151 is mounted in the mounting space. The circuit board 153 is accommodated in the mounting space, and the circuit board 153 includes a control circuit 1531, the control circuit 1531 is electrically connected with the display screen 151, and the control circuit 1531 is used to control the display screen 151 to display the information of the two-wheeled vehicle 100.

[0027] It should be noted that the information displayed by the display screen 151 needs to be viewed by the user, so the mounting shell 152 needs to be arranged in a structure that can view the display screen 151, for example, the area of the mounting shell 152 corresponding to the display screen 151 can be made of transparent material, or an installation opening can be provided to enable the user to view the display screen 151. Alternatively, the mounting shell 152 is provided with an installation opening, and the display screen 151 is mounted on the installation opening, so that the mounting space is formed by the mounting shell 152 and the display screen 151 together, and the user can directly view the display screen 151.

[0028] It is understandable that the display screen 151 can be used to display various information about the two-wheeled vehicle 100, such as the battery level, speed, and steering status of the two-wheeled vehicle 100.

[0029] An NFC coil 154 is mounted on circuit board 153 and connected to control circuit 1531. The distance between the NFC coil 154 and the outer side of display screen 151 is less than or equal to the maximum sensing distance of the NFC coil 154. The NFC coil 154 is used to sense the key signal emitted by the NFC key and send the sensed key signal to control circuit 1531. The outer side of display screen 151 refers to the side of display screen 151 that displays information, that is, the side of display screen 151 that faces the outside world for the user to view.

[0030] It is understandable that when the NFC coil 154 senses the key signal emitted by the NFC key, the NFC coil 154 sends the key signal to the control circuit 1531, and the control circuit 1531 can unlock and power on the two-wheeled vehicle 100 according to the key signal.

[0031] In this embodiment, the NFC coil 154 is mounted on the circuit board 153 and connected to the control circuit 1531. The NFC coil 154 can send the sensed key signal to the control circuit 1531, thereby enabling the two-wheeled vehicle 100 to unlock and power on. That is, in this embodiment, the NFC unlocking function of the two-wheeled vehicle is jointly implemented by the NFC coil 154 and the control circuit 1531, eliminating the need for a separate signal output module and reducing the space required by the NFC assembly. Furthermore, since the NFC coil 154 is mounted on the circuit board 153, and the distance between the NFC coil 154 and the outer side of the display screen 151 is less than or equal to the maximum sensing distance of the NFC coil 154, simply bringing the NFC key close to or placing it against the surface of the display screen 151 is sufficient for the NFC coil 154 to sense the key signal. Therefore, there is no need to set a separate marker in the display instrument 15 to indicate the unlocking position, making it convenient for users to unlock the two-wheeled vehicle 100 via NFC. Thus, in this embodiment, the space required by the NFC assembly is reduced, and there is no need to set a separate marker in the display instrument 15 to indicate the unlocking position.

[0032] Based on this, in this embodiment of the application, since the space required for the NFC assembly can be reduced and no additional signal output module and marker are required, the manufacturing cost of the display instrument 15 can be reduced, thereby reducing the cost of the two-wheeled vehicle 100.

[0033] In some embodiments, such as Figure 2 As shown, the NFC coil 154 can be arranged around the periphery of the circuit board 153. This increases the sensing range of the NFC coil 154. The NFC coil 154 can be printed on the periphery of the circuit board 153.

[0034] Please refer to Figure 2 , the mounting shell 152 can include a first shell 1521 and a second shell 1522, the first shell 1521 covers the second shell 1522 to form a mounting space. By separating the first shell 1521 and the second shell 1522 cover to form a mounting space, the device inside the display instrument 15 can be installed on the second shell 1522 first, and then the first shell 1521 is covered on the second shell 1522, and the first shell 1521 and the second shell 1522 are fixedly locked or buckled, and the assembly of the display instrument 15 is completed. In this way, the assembly of the display instrument 15 can be facilitated.

[0035] The first shell 1521 is provided with a visible area, and the visible area is opposite to the display screen 151. The display screen 151 is installed at the visible area. The circuit board 153 is installed in the second shell 1522 and located at the lower side of the display screen 151.

[0036] The visible area of the first shell 1521 can be used by the user to view the display screen 151. The circuit board 153 is installed in the second shell 1522 and located at the lower side of the display screen 151, so that the connection between the circuit board 153 and the display screen 151 can be facilitated, and the connection line can be prevented from being exposed in the visible area.

[0037] Further, the mounting shell 152 further includes a transparent plate 1523, and the transparent plate 1523 is installed in the first shell 1521 to form a visible area. By installing a transparent plate 1523 on the first shell 1521 to form a visible area, the display screen 151 can be conveniently viewed, and the outside dust, rainwater and the like can be prevented from entering the display instrument 15, thereby realizing the protection of the display screen 151 and other devices inside the display instrument 15.

[0038] Please refer to Figure 2 , the display instrument 15 can further include a mounting bracket 155, and the mounting bracket 155 is arranged on the upper side of the circuit board 153 and used for mounting the display screen 151. The display screen 151 can be clamped in the mounting bracket 155, and the mounting bracket 155 supports the display screen 151 on the upper side of the circuit board 153 and close to the visible area, so as to realize the stable installation of the display screen 151.

[0039] The circuit board 153 can be fixedly installed in the second shell 1522, the mounting bracket 155 is clamped on the second shell 1522, the mounting bracket 155 and the display screen 151 completely shield the circuit board 153, and after the first shell 1521 is covered on the second shell 1522, the display screen 151 is opposite to the visible area.

[0040] In the embodiments of the present application, the key signal can include a key identifier of the NFC key, and the control circuit 1531 can be further configured to acquire the key identifier of the NFC key according to the key signal, compare the key identifier with the pre-stored identification information, and cause the two-wheeled vehicle 100 to be unlocked and powered on when the key identifier is consistent with the pre-stored identification information.

[0041] In the embodiments, the control circuit 1531 can be in communication connection with an external terminal (not shown in the figure), and the pre-stored identification information can be sent to the control circuit 1531 for storage through the external terminal. Alternatively, the control circuit 1531 can have a read-write function, when the control circuit 1531 is in a read-write state, the NFC coil 154 senses the key signal and sends the key signal to the control circuit 1531, the control circuit 1531 acquires the key identifier from the key signal, and stores the acquired key identifier as the pre-stored identification information. It can be understood that the pre-stored identification information can include one or more key identifiers. When the pre-stored identification information includes more than one key identifier, the control circuit 1531 can compare the acquired key identifier with the plurality of key identifiers in the pre-stored identification information one by one, and when the acquired key identifier is consistent with any key identifier in the pre-stored identification information, the control circuit 1531 causes the two-wheeled vehicle 100 to be unlocked and powered on.

[0042] As shown in FIG. 1, Figure 4 In some embodiments, the two-wheeled vehicle 100 further includes a body controller 16 (BCM) 16, and the body controller 16 is in communication connection with the control circuit 1531. The control circuit 1531 is further configured to send an unlock signal to the body controller 16 when the key identifier is consistent with the pre-stored identification information, and the body controller 16 controls the two-wheeled vehicle 100 to be unlocked and powered on according to the unlock signal.

[0043] That is, the body controller 16 can control the two-wheeled vehicle 100 to be unlocked and powered on according to the unlock signal. It can be understood that the body controller 16 controls the two-wheeled vehicle 100 to be unlocked and powered on only when the unlock signal is received and the two-wheeled vehicle 100 is in an anti-theft state. Wherein, the two-wheeled vehicle 100 in the anti-theft state means that the two-wheeled vehicle 100 is powered off and its anti-theft system (not shown in the figure) locks the two-wheeled vehicle 100, and the body controller 16 can acquire whether the two-wheeled vehicle 100 is in the anti-theft state from the anti-theft system.

[0044] In the embodiments of the present application, the body controller 16 can be in communication connection with the control circuit 1531 through a communication bus. Wherein, the communication bus can be, for example, a one-wire bus, a CAN bus, an RS485 bus, etc.

[0045] It can be understood that the vehicle body controller 16 can be used to obtain the state information of the two-wheeled vehicle 100 and control some components of the two-wheeled vehicle 100 according to the state information of the two-wheeled vehicle 100. Moreover, the vehicle body controller 16 can send the obtained state information of the two-wheeled vehicle 100 to the control circuit 1531 of the display instrument 15 through the communication bus, and then the control circuit 1531 controls the display screen 151 to display the state information.

[0046] The two-wheeled vehicle 100 can further include a vehicle control unit (VCU), a motor control unit (MCU) and an electrical park brake (EPB).

[0047] Specifically, the vehicle body controller 16 can be connected with the components such as the steering lamp, the brake lamp and the anti-theft system of the two-wheeled vehicle 100 to control the working of the components such as the steering lamp, the brake lamp and the anti-theft system according to the state of the two-wheeled vehicle 100.

[0048] It can be understood that when the two-wheeled vehicle 100 is an electric two-wheeled vehicle, the two-wheeled vehicle 100 includes a power battery (not shown in the figure), and the vehicle body controller 16 can be further connected with the power battery to obtain the battery state information, which can include the power and temperature of the power battery, and then the vehicle body controller 16 can send the battery state information to the control circuit 1531 through the communication bus, so that the control circuit 1531 controls the display screen 151 to display the battery state information for the user to confirm whether the battery needs to be charged.

[0049] When the two-wheeled vehicle 100 is a fuel two-wheeled vehicle, the two-wheeled vehicle 100 includes a fuel tank (not shown in the figure), and the fuel tank can be provided with a fuel quantity detection device.

[0050] It can be understood that when the communication bus is a CAN bus, the control circuit 1531, the vehicle body controller 16, the vehicle control unit and the motor control unit can be distributedly connected to the CAN bus. Of course, other controllers of the two-wheeled vehicle 100, such as a brake controller and an anti-lock controller, can also be connected to the CAN bus, and the signals of the controllers are transmitted through the CAN bus.

[0051] AsFigure 5 As shown, in some embodiments, the two-wheeled vehicle 100 can further include a smart central control 17, which is communicatively connected with the control circuit 1531.
