[0029] Please refer to Figures 1 to 8 In the present embodiment, a vehicle limiting device is applied between the bottom of a vehicle and the ground, and the vehicle limiting device comprises at least one support member 13 and first and second force receiving members 11 and 12 connected to the two ends of the support member 13 respectively, each of the support member 13, the first and second force receiving members 11 and 12 together constitutes a frame structure 1 having at least one accommodating space 14 for accommodating a vehicle wheel 5, the support member 13 and the two force receiving members each have a bottom side for contacting the ground 6 and a top side arranged opposite to the bottom side, one of the first and second force receiving members 11 and 12 will block the rotation of the vehicle wheel 5 when it is rolled over, and the other force receiving member can be supported by the support member 13 to be lifted and abut against the bottom of the vehicle. When the support member 13 is placed on the ground 6, since the first and second force receiving members 11 and 12 are connected to the two ends of the support member 13, when the vehicle wheel 5 rolls over any one of the first and second force receiving members 11 and 12, the other force receiving member can be supported by the support member 13 to be lifted and abut against the vehicle chassis, realizing the floating installation of the vehicle limiting device, thereby limiting the movement of the vehicle, which can not need to be installed on the ground 6, has lower use cost and simple structure; at the same time, the vehicle wheel 5 of the vehicle is located in the accommodating space 14, and the support member 13, the first and second force receiving members 11 and 12 are not in direct contact with the vehicle, so there is no legal risk of infringing the property rights of the vehicle owner, which greatly increases the actual application field thereof.

[0030] In the present embodiment, the number of the support members 13 and the arrangement mode among the support member 13, the first and second force receiving members 11 and 12 have multiple cases.

[0031] Please refer to Figure 1 and Figure 2In the first embodiment of the present embodiment, the vehicle limiting device comprises two supports 13 arranged in parallel and oppositely, and a first force receiving member 11 and a second force receiving member 12 arranged on the two supports 13. At least one of the first force receiving member 11 and the second force receiving member 12 is connected to the support 13 in a detachable manner, and the two supports 13, the first force receiving member 11 and the second force receiving member 12 can jointly form an accommodating space 14. Specifically, the two supports 13 are arranged in parallel, and the first force receiving member 11 and the second force receiving member 12 are arranged in parallel, so that the first force receiving member 11, the support 13, the second force receiving member 12 and the support 13 are sequentially connected to form a rectangular frame structure 1. The first force receiving member 11 and the second force receiving member 12 can be detachably connected to the support 13, or one of the first force receiving member 11 and the second force receiving member 12 can be detachably connected to the support 13. Preferably, the two ends of the first force receiving member 11 are connected to a support 13 respectively, one end of the second force receiving member 12 is rotatably connected to a support 13, and the other end is detachably connected to the other support 13. Either of the first force receiving member 11 and the second force receiving member 12 has a bottom and a top arranged oppositely to the bottom. Further, the first force receiving member 11 is fixedly connected to the support 13, one end of the second force receiving member 12 is rotatably connected to a support 13, and the other end is detachably connected to the other support 13. This can ensure that the frame structure 1 has sufficient connection strength between components, and can also realize opening and closing of the accommodating space 14 of the frame structure 1 by the second force receiving member 12. It can be understood that the first force receiving member 11 and the support 13 can also be connected by a hinge or a plug-in connection. At this time, the frame structure 1 can be folded for storage, and the vehicle limiting device is convenient to carry. When one end of the second force receiving member 12 is detached from the support 13, the accommodating space 14 of the frame structure 1 is in an open state, and the wheel 5 can enter or exit the accommodating space 14. When one end of the second force receiving member 12 is assembled on the support 13, the accommodating space 14 of the frame structure 1 is in a closed state, and the wheel 5 is limited in the accommodating space 14, so as to realize the frame structure 1 limiting the movement of the vehicle.

[0032] Please refer to Figure 1 and Figure 2In the embodiment, the bottom side of the support 13 is used to contact the ground, and the length of the bottom side of the support 13 is greater than or equal to the length of the top side of the support 13. The bottom of any one of the first force receiving member 11 and the second force receiving member 12 is arranged between the bottom side of the support 13 and the top side of the support 13. When the wheel 5 rolls on the first force receiving member 11 and the second force receiving member 12, the contact point of the support 13 with the ground 6 is located within the intersection point of the extension direction of the force received by the corresponding force receiving member and the ground 6. Specifically, the bottom side of the support 13 can be in a zigzag shape or an arc shape. The zigzag shape has a lower processing cost than the arc shape, and is preferably in a zigzag shape. The top side is in a straight line shape, so that the support 13 forms a seesaw structure when placed on the ground 6, which is beneficial to the force receiving member being lifted by the support 13 and abutting against the vehicle chassis. It can be understood that when the length of the bottom side of the support 13 is greater than the length of the top side of the support 13 and the bottom side of the support 13 is in a zigzag shape, the support 13 is in an inverted trapezoidal shape, and the length of the part of the bottom side of the support 13 in contact with the ground 6 is less than the length of the top side of the support 13. When the length of the bottom side of the support 13 is equal to the length of the top side of the support 13, the support 13 is in a rectangular shape. The first force receiving member 11 and the second force receiving member 12 can both be rectangular plates, so that the force receiving member does not deform after being subjected to pressure, and the service life of the first force receiving member 11 and the second force receiving member 12 is improved. The bottom of any one of the first force receiving member 11 and the second force receiving member 12 is arranged between the bottom side of the support 13 and the top side of the support 13, so that when the support 13 contacts the ground 6, there is a gap between the first force receiving member 11 and the ground 6 and between the second force receiving member 12 and the ground 6, which is beneficial to the support 13 forming a seesaw structure when placed on the ground 6. The support 13 comprises a rectangular portion and an inverted trapezoidal portion fixedly connected to the rectangular portion. The bottom and the top of the force receiving member are flush with the two side edges of the rectangular portion, so that the force receiving member has sufficient height and rigidity, and the gap between the force receiving member and the ground 6 is large, so that the lifting height of the support 13 is high.

[0033] Please refer to Figure 1 and Figure 2 In the embodiment, the locking member 2 is installed at one end of the support 13, and the second force receiving member 12 is detachably connected to the support 13 through the locking member 2.

The display member 3 can also be hingedly connected to the bottom side of the support 13. After the limiting device is installed, the display member 3 is turned open and placed on the ground for the vehicle owner to watch. The alarm assembly 4 is installed at the end of the frame structure 1 away from the locking member 2, so that the sensor can detect the displacement of the wheel 5 in real time. According to actual needs, the length of the force receiving member is greater than 20 cm. After the locking member 2 is loosened, the second force receiving member 12 can be rotated to open the containing space 14.
