[Brief description of the drawings]

[0006] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the present invention is described in detail hereinafter with reference to the drawings and embodiments. [Figure 1] FIG. 2 is a perspective view showing the present invention in a folded state; [Diagram 2] FIG. 2 is a perspective view showing the present invention in an unfolded state. [Diagram 3] FIG. 2 is a perspective view of the present invention in a locked state; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] As shown in Figs. 1 to 3, the portable lever type vehicle locking structure of the present invention includes at least one pair of lock levers (two lock levers) that rotate about a rotation axis, and the locking structure can be unlocked and locked by rotating the lock levers about the rotation axis. The free end of the first lock lever (1) is provided with an abutment portion (2) for contacting the tread of the tire (3). The second lock lever (4) is provided with an abutment portion (2) for contacting the tread of the tire (3) near the free end of the second lock lever (4) and the rotation axis. When locked, the three abutment portions (2) of the first lock lever (1) and the second lock lever (4) each come into contact with the tread of the tire (3), forming a triangular locking structure as a whole. All of the interior angles of the triangle are smaller than 90°. This allows for stable and reliable locking and prevents the wheels from coming off the locking structure. The locking operation is performed by turning the first lock lever (1) and the second lock lever (4) to the locked position, and the angle between the first lock lever (1) and the second lock lever (4) is fixed by the locking structure, and locking is realized. In addition, since the locking structure does not come into contact with the wheel when locked, the surface of the wheel is not damaged. When unlocking, in order to release the locked state of the locking structure, the lock lever is rotated again around the rotation axis so that the abutment part (2) separates from the tread of the tire (3), and then the locking structure is removed from the tire (3), and unlocking is realized. At this time, if the lock lever is further rotated around the rotation axis until the two lock levers overlap, the two lock levers are stored, and the volume of the entire locking structure is significantly reduced, making it easy to store and carry.

[0008] Since the sizes of tires (3) of vehicles are different, in order for the locking structure to be applicable to tires (3) of various sizes and to realize a more compact volume of the locking structure, the first locking lever (1) and the second locking lever (4) are both designed to be adjustable in length, and the adjusted length can be fixed, so that a structure that can be extended and fixed can be obtained. During the locking operation, the first locking lever and the second locking lever are first extended to a length that matches the size of the wheel. At this time, the distance between the two abutment parts (2) of the second locking lever (4) also increases accordingly. Next, the two locking levers are spread, and the lengths of the two locking levers are appropriately adjusted so that the abutment parts (2) can properly contact the tread of the tire (3). Finally, after the length of the locking levers is fixed, the angle of the two locking levers is fixed by the locking structure.

[0009] In order to allow the telescopic structure of the lock lever to automatically adapt to different tire (3) sizes and achieve locking at different lengths, a wire structure is provided inside the first lock lever (1) and the second lock lever (4) to fix the length of the telescopic structure. When not fixed, the wire structure is in a loose state, and the length of the lock lever can be easily adjusted. When the lock structure is installed near the wheel, the two lock levers are adjusted to an appropriate locking angle, the angle of the two lock levers is fixed by the lock structure (fixing structure), and finally, the wire structure is contracted to bring the abutment parts (2) of the three lock levers into contact with the wheel tread, and the length of the wire structure is fixed. This completes the adjustment of the length of the wire structure. After unlocking, the lock structure can be shortened by shortening the length of the first lock lever and the second lock lever, thereby shortening the overall length of the lock structure. This allows the overall volume of the lock structure to be further reduced. The contraction of the wire structure can be achieved by a winding structure provided in the lock structure.

[0010] The second lock lever (4) may be designed as a locking base placed on the ground, so that the locking structure can be easily placed on the ground during installation and can be easily operated. The first lock lever (1) is installed on the locking base via a rotating shaft. At least one side of the locking base is provided with an opening, and the locking base can be inserted below the tire (3) through the opening after the locking base is pulled open by the telescopic structure. After the first lock lever (1) is pulled open by the telescopic structure, it is rotated to the top of the tire (3) via the rotating shaft, and then the relative angle is fixed (locked), and the abutment part (2) is abutted against the tread, and the telescopic structures of the first lock lever and the second lock lever are fixed, thereby achieving the locking of the locking structure.

[0011] In order to prevent the locked locking structure from being pulled out along the axial direction of the wheel, the present invention adopts the following structure: 1. When the first locking lever (1) and the second locking lever (4) are respectively installed at both ends of the rotating shaft, and the first locking lever (1) and the second locking lever (4) form a relative angle, the first locking lever (1) and the second locking lever (4) are located on both sides of the tire (3). As a result, the locking structure on either side of the tire (3) cannot be pulled out along the axial direction. 2. When the second locking lever (4) is a locking base structure, a blocking surface is provided on the surface facing the side of the locking base on which the first locking lever (1) is provided, and the blocking surface is installed on the locking base and / or the abutment portion (2) of the first locking lever (1) and / or the rotating shaft, and the first locking lever (1) and the blocking surface can prevent the locking structure from being pulled out along the axial direction of the wheel.

[0012] The locking of the portable vehicle locking structure is mainly realized by the locking structure fixing the relative angle of the lock lever. The realization of locking the relative angle needs to be designed according to the connection structure between the lock lever and the rotating shaft. For example, the lock lever and the rotating shaft may be connected by a gear structure. In this case, locking can be realized by the relative motion of the gear structure. The gear structure can be realized by using gears of different sizes, large and small. In addition, such a gear structure generally uses a motor, and the rotational motion of the motor is transmitted to the lock lever via the gear structure, and the lock lever is rotated relative to the rotating shaft, thereby realizing unlocking and locking of the lock structure. In this case, fixing of the relative angle (locking) can be realized depending on whether the motor can rotate. Specifically, when a small gear is connected to the lock lever or the rotating shaft, and a large gear combined with the small gear cannot rotate, that is, when the abutment part abuts against the tread of the wheel, and the torque formed by the small gear is smaller than the torque at which the large gear can rotate, the large gear cannot rotate and the rotation of the motor also stops. At this time, the large gear stops, and the relative angle is fixed (locked). If a more reliable lock is required, the lock can be achieved by locking the gear. The above description is merely an example of one structure for rotating the lock lever, and the present invention is not limited thereto. For example, the present invention may use a sprocket structure, etc., and the corresponding locking structure may be freely designed according to the specific driving structure as long as the locking effect can be achieved. Furthermore, the relative angle of the two lock levers may be fixed by a connecting load to achieve locking.

[0013] In order to realize an intelligent Internet of Things (IoT) that allows a user to lock the locking mechanism or know the locking status through a mobile device such as a mobile phone, the present invention can add a control circuit. The control circuit may generally include a driving module for driving the locking mechanism and a wireless communication module for communicating with external peripheral devices. The output end of the driving module is connected to the electronic driving components of the locking mechanism. The wireless communication module can not only lock or unlock the locking mechanism through wireless communication, but also know the operating status of the locking mechanism.

[0014] In addition, the locking mechanism may be provided with an LED so that the user can easily understand the operating status of the locking mechanism. Different indication effects of the LED can be used to grasp the status of the locking mechanism, for example, whether the locking mechanism is locked or unlocked by different lamp colors.

[0015] In addition, since it is necessary to provide power to the electronic devices related to the lock structure, a solar panel (photovoltaic power generation module) that charges the built-in battery may be added. This makes it possible to prevent the operation of various electronic systems from being affected when the battery power is insufficient.

[0016] A GPS positioning module may be provided within the lock structure, allowing the user to track and locate the lock structure and thus the vehicle.
