It is noted that the terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

The terms "comprises," "comprising," and "having," and any variations thereof, in the description and claims of this application are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Because the existing carrier has a complex structure and poor repeated use precision, and positioning errors are easy to occur in the using process, so that the problem of wheel damage is caused, the inventor of the application develops a centering carrier 1 with a variable wheel base, as shown in fig. 1 to 11, the centering carrier 1 comprises two groups of synchronizing components 11 and limiting components 12, the synchronizing components 11 are provided with two groups and are respectively arranged at the front side and the rear side of the centering carrier 1, and the synchronizing components 11 are suitable for synchronously moving away from or towards each other along the front-rear direction under the driving of a driving component 100; the limiting assemblies 12 are provided with two groups and extend in the left-right direction, one ends of the limiting assemblies 12 are connected to the side walls of the same sides of the synchronizing assemblies 11 respectively, the other ends of the limiting assemblies 12 are suitable for entering the bottom of the automobile 300, the synchronizing assemblies 11 are suitable for driving the limiting assemblies 12 to move in the front-back direction and sequentially or simultaneously abut against wheels, the automobile 300 is driven to move in the front-back direction, and the front wheels and the rear wheels of the automobile 300 are located in the middle position relative to the centering carrier 1. It should be noted that synchronous moving away or toward each other means that the two sets of synchronous components 11 move in the front and back directions simultaneously, and the two sets of synchronous components 11 move at the same speed and in opposite directions. It is readily apparent that there are many different embodiments of synchronous phase-off or phase-on motion, including the use of two servomotors in synchronism, with the same rotational speed; or a symmetrically arranged link mechanism is used, so that the moving speeds of the two groups of synchronous components 11 are the same, and the directions are opposite.

The inventor of the application removes a vehicle carrying plate which needs to be matched with a conventional carrier, can realize the positioning and centering functions of the automobile 300 only by means of the centering carrier 1, and can directly realize the change of the position of the centering carrier 1 by means of the translation mechanism 2 and the lifting mechanism 3, thereby realizing the function of changing the position of the automobile 300, wherein the synchronous components 11 synchronously move away or towards each other along the front-back direction under the driving of the driving component 100, wherein the synchronous away means that the synchronous components 11 simultaneously extend outwards as shown in the state of fig. 2 and then are changed into the state as shown in fig. 3; synchronous movement towards each other means that the synchronising members 11 are moved inwards at the same time, as in the state of fig. 3, into the state of fig. 2. Wherein, when the synchronous phase moves, the outer sides of the limiting components 12 arranged along the left and right direction are suitable for abutting against the front and rear wheels of the automobile 300, and in the initial state, the distance between the two groups of limiting components 12 is less than the minimum axle distance 2200mm of the common automobile 300; when the synchronous opposite movement is carried out, the inner sides of the limiting assemblies 12 arranged along the left-right direction are suitable for abutting against the front wheels and the rear wheels of the automobile 300, and in the initial state, the distance between the two groups of limiting assemblies 12 is 3400mm larger than the maximum axle spacing of the ordinary automobile 300.

( It is easy to understand that, when the two sets of limiting assemblies 12 are both abutted against the wheels, the sensor can also be used on the centering carrier 1 to stop the movement of the synchronizing assembly 11; of course, it is also possible to use a visual recognition system to identify the inter-axle distances of different vehicles 300 and thus to determine the distance that the synchronising assembly 11 needs to move )

The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and these changes and modifications are intended to be within the scope of the application as claimed. The scope of protection claimed by this application is defined by the following claims and their equivalents.
