Referring to Figures 1, 2A, 2B, 3A, 3B and 6 , the present creation is a vehicle ceiling device comprising:  The two lifting portions 10 are used for lifting and lowering.  The two flat plate portions 20 are provided corresponding to the two lifting portions 10 for use as a support structure. Each of the flat portions 20 has a bottom surface 21, a top surface 22, two side surfaces 23, a first end surface 24, and a second end surface 25. The bottom surface 21 is coupled to the corresponding lifting portion 10 and can be moved up and down; the side surface 23 is provided with at least one L-shaped baffle 231 for the top surface 22 At least one orbital space M is formed between them. The direction of the line connecting the first end face 24 and the second end face 25 is defined as a longitudinal axis direction X.  The plurality of extending plate portions 30 are corresponding to the two flat plate portions 20 and are respectively disposed in the corresponding track spaces M. Each of the extending plate portions 30 has an outer end surface 31, an inner end surface 32, and a lower surface 33. An upper surface 34 and a pair of plate sides 35. The outer end surface 31 and the inner end surface 32 are opposite to each other and are located between the lower surface 33 and the upper surface 34. The lower surface 33 is slidable relative to the top surface 22 along the longitudinal axis direction X such that the extension plate portion 30 has at least a retracted position P1 (see FIG. 4A) and an extended position P2 (see 4B, 5th and 8th). At the retracted position P1, the outer end surface 31 of the extension plate portion 30 does not extend beyond the first end surface 24 (see FIG. 7) and the second end surface 25. In the extended position P2, the outer end surface 31 of the extension plate portion 30 extends beyond one of the first end surface 24 and the second end surface 25.  Thereby, each of the extension plate portions 30 can be independently moved to the extended position P2 for lengthening the corresponding support length of the flat plate portion 20 (refer to FIG. 5, for example, a flat plate portion length L1 plus one extension) The plate portion has an extension length L2, or a flat plate portion length L1 plus two extension plate portion extension lengths L2).  In practice, each lifting portion 10 can be a combination structure of a power cylinder (usually a hydraulic cylinder) and a connecting rod group (refer to the lifting device of the Republic of China Invention Patent No. 200942135).  Each L-shaped baffle 231 is coupled to the shape of each side surface 23, and may be at least one of a locking structure and a welded structure.  When it is a locking structure, a plurality of locking components 23A are provided to achieve locking.  When it is a welded structure, it has a plurality of welding point pieces 23B which are produced after the welding process (refer to FIG. 3C. Of course, FIG. 3C is only an example, in fact, the position and the number of the welding point pieces 23B are not limited as long as the structure can be achieved. Anyone can be stable).  This creation can further include:  At least two protrusion-restricting structures A1 (as shown in FIG. 7) are respectively disposed on the top surface 22 and one of the L-shaped baffles 231, and adjacent to the first end surface 24 and the second end surface, respectively. 25.  Each of the extension plate portions 30 corresponds to at least two protrusions A1, and has at least two locking structures 36, respectively, from the corresponding plate side 35 to the corresponding track space M extend.  Thereby, when the extension plate portion 30 is slid in the rail space M to the extended position P2, the locking structure 36 is blocked by the protruding limit structure A1 (as shown in FIG. 4B). The extension plate portion 30 is not separated from the orbital space M.  Further, this creation can further include:  The at least two retracting structures A2 are respectively protruded from the top surface 22 and the L-shaped baffle 231, and are respectively away from the first end surface 24 and the second end surface 25.  Thereby, when each of the extension plate portions 30 is relatively slid into the retracted position P1 in the orbital space M, the inner end surface 32 is correspondingly retracted into the limit structure A2 (as shown in FIG. 4A). Show) stop.  Moreover, each of the extension plate portions 30 can further include a load bearing device 37; the load bearing device 37 is disposed on the upper surface 34 for use as a load-bearing buffer structure.  It is well known in the industry that vehicles such as cars and recreational vehicles are fixed with a plurality of jacking positions PA (see Figure 10). The plurality of jacking positions PA are structural reinforcements of the vehicle, which are located at the front, the rear and the two. Near the front and rear wheels. It is known that a vehicle ceiling device mainly contacts a plurality of jacking positions PA of a vehicle with a fixed flat portion to lift the vehicle to perform chassis maintenance.  The important point is that the wheelbase of a general car is relatively fixed, and the jacking position PA is usually also within the contact range of the flat portion (92) of the vehicle ceiling device (as shown in FIG. 11A), but the number of large CCs is In order to be comfortable and spacious, the SUV has a tendency to grow, so that the jacking position PA exceeds the contact range of the flat plate portion (92), which may cause a problem that the position where the jacking position is weak and deformed. For this part, the at least one L-shaped baffle 231 is respectively disposed on the two side faces 23 of the flat plate portion 20, and at least one track space M is formed on the top surface 22. And the at least one pair of track spaces M are provided, and the plurality of pairs of extension plates 30 are provided, whereby when the wheelbase of the vehicle is short, the pair of extension plates 30 can be located at the retracted position P1 without being pulled out for use. And when a vehicle with a longer wheelbase is encountered, at least one of the pair of extension plates 30 can be moved to the extended position P2 (refer to FIG. 5, for example, the length of the flat portion L1 plus the extension length of the extension plate portion) L2), or both extension plate portions 30 are pulled out to the extended position P2 (refer to FIG. 5, the flat plate portion length L1 plus two extension plate portion extension length L2), to achieve the flat plate portion 20 extended contact The jacking position PA.  The advantages and functions of this creation are as follows:  [1] The extension plate can be elastically pulled out to the vehicle with a higher top wheelbase. The present invention cooperates with a vehicle with a longer wheelbase to pull at least one of the two extension plates as an extension of the flat portion, and can contact the top position of the vehicle to secure the vehicle with a longer top wheelbase. Therefore, the extension plate portion can elastically pull out the vehicle applied to the top and the longer wheelbase.  [2] Easy to retrofit with known devices. This creation can be known that the L-shaped baffle is directly added on both sides of the flat part of the top machine, and then the extension plate can be extended, that is, the modification can be completed, and the whole set of known devices can be directly used without removing the additional device. Therefore, it is easy to directly modify it with a known device.  The above is only a detailed description of the present invention by way of a preferred embodiment, and any modifications and variations of the embodiments are possible without departing from the spirit and scope of the present invention.
