Terms used in the specification of the present invention are merely for description of the specific embodiments, and are not intended to limit the present invention. A term “and/or” used in this specification includes any or all combinations of one or more related listed items.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other if there is no conflict.

Referring to FIG. 1 and FIG. 2, a wheel aligner 100 provided in an embodiment of the present invention includes at least one camera assembly 10 (FIG. 1 shows an embodiment in which two camera assemblies 10 are included). The camera assembly 10 includes a shielding assembly 11 and a camera device 12 accommodated in the shielding assembly 11. The shielding assembly 11 is configured to expose a lens of the camera device 12 when the camera device 12 is in operation and shield the lens of the camera device 12 when the camera device 12 is in not in operation.

According to the wheel aligner 100 in the embodiments of the present invention, the camera device 12 is disposed in the shielding assembly 11. The shielding assembly 11 exposes the lens of the camera device 12 when the camera device 12 is in operation and the shielding assembly 11 shields the lens of the camera device 12 when the camera device 12 is not in operation. The lens of the camera device 12 can be effectively prevented from being polluted by the surroundings while ensuring proper operation of the camera device 12.

In some embodiments, referring to FIG. 1, the shielding assembly 11 includes a housing 111, a shielding cover 112 and a power device (not shown in the figure). The camera device 12 is accommodated in the housing 111. The housing 111 is provided with an opening at a position corresponding to the lens of the camera device 12. The shielding cover 112 is disposed at the opening. The shielding cover 112 is connected to the power device. The power device is configured to drag the shielding cover 112 to move relative to the opening, to reveal or shield the opening. A direction in which the power device drags the shielding cover 112 to move relative to the opening is not limited in the embodiments of the present application. For example, the power device drags the shielding cover 112 to rotate about an axis to toward or away from the opening, thus revealing or shielding the opening. Alternatively, the power device drags the shielding cover 112 to move parallel to the camera device 12, to reveal or shield the opening. When the camera device 12 starts operating, that is, changes from the non-operating state to the operating state, the power device drags the shielding cover 112 to move relative to the opening, to reveal the opening, so that the lens of the camera device 12 is exposed, thus ensuring that the camera device 12 captures an image properly. When the camera device 12 stops operating, that is, changes from the operating state to the non-operating state, the power device drags the shielding cover 112 to move relative to the opening, to shield the opening, so that the shielding cover 112 shields the lens of the camera device 12, thus preventing the lens of the camera device 12 in operation from being polluted by the surroundings.

Specifically, in some embodiments, the power device includes a motor unit and a transmission assembly that are connected to each other (not shown in the figure). The motor unit is configured to drive the transmission assembly to move and the transmission assembly is configured to drive the shielding cover 112 to move relative to the opening. The motor unit may adopt a structure shown in FIG. 2, which includes a motor 113, a motor driver 114 and a controller 115. The motor 113 is electrically connected to the controller 115 through the motor driver 114. The controller 115 is configured to receive a control instruction and control the motor driver 114 according to the control instruction, so that the motor driver 114 drives the motor 113 to rotate, thus driving the transmission assembly to move.

If the power device drags the shielding cover 112 to move parallel to the camera device 12, the transmission assembly may be a transmission assembly that is capable of converting rotational motion into linear motion in the prior art, for example, a synchronous wheel, a synchronous belt, or the like. The synchronous wheel is disposed on a rotating shaft of the motor 113. When the motor 113 rotates, the rotating shaft drives the synchronous wheel to rotate, so that the synchronous belt drives the transmission assembly to move, which converts rotational motion of the motor 113 into linear motion of the shielding cover 112. In this way, the shielding cover 112 can move relative to the opening under driving of the motor 113. Specifically, the shielding cover 112 may be controlled to reveal the opening and shield the opening respectively through control of forward rotation and reverse rotation of the motor. The motor driver 114 may be powered by an external power supply. Alternatively, as shown in FIG. 2, the motor driver 114 may be powered by a power adapter 60 connected to the motor driver 114.

Specifically, in some embodiments, referring to FIG. 1, the shielding cover 112 includes a first shielding body and a second shielding body that form a circle. The opening is also circular. In some embodiments, in order to enhance sealing, a size of the shielding cover 112 is greater than a size of the opening, that is, a diameter of the circle formed by the first shielding body and the second shielding body is greater than the diameter of the opening. For example, the diameter of the circle formed by the first shielding body and the second shielding body is 1.2 times the diameter of the opening.

In some embodiments of the wheel aligner 100, the wheel aligner 100 further includes a host 50. The host 50 is electrically connected to the controller 115. The host 50 is further electrically connected the camera device 12. To use the camera device 12, a user may send a first control instruction to the camera device 12 through the host 50 for controlling the camera device 12 to start operating. In addition, the host 50 sends a first driving instruction to the controller 115 for controlling the motor driver 114 to drive the motor 113 to rotate, so that the motor 113 drives the shielding cover 112 to move relative to the opening through the transmission assembly to reveal the opening. After use, the user may send a second control instruction to the camera device 12 through the host 50 for controlling the camera device 12 to stop operating. In addition, a second driving instruction is sent to the controller 115 for controlling the motor driver 114 to drive the motor 113 to rotate, so that the motor 113 drives the shielding cover 112 to move relative to the opening through the transmission assembly to shield the opening. Specifically, the host 50 may be connected to the controller 115 through a USB interface or other common interfaces. In some other embodiments, a wireless receiving module may also be disposed on the controller 115 and the camera device 12. A first control instruction, a second control instruction, a first driving instruction and a second driving instruction that are delivered by other electronic devices through wireless transmission are received through the wireless receiving module. Alternatively, a control key may be arranged in the wheel aligner. The user implements a function of the first driving instruction or the second driving instruction through the control key.

In some embodiments of the wheel aligner 100, referring to FIG. 1, the wheel aligner 100 further includes a base 40, a supporting rod 30 and a connecting rod 20. The connecting rod 20 is configured to be connected to the camera assembly 10 and the supporting rod 30 and the base 40 are configured to support the connecting rod 20 and the camera assembly 10. In some other embodiments, the camera assembly 10 may also be supported by a supporting table.
