The locking between the locking sleeve 360 and the rotating spindle 132 can be achieved by friction between the two, or by some combination of protrusions and grooves. The actuator 310 may be a telescopic motor or other link structure, as long as the actuator can drive the locking sleeve 360 to slide on the mounting cylinder 320. In addition, the inner wall of the mounting cylinder 320 can be provided with a sliding groove along the axial direction thereof, the outer wall of the locking sleeve 360 is provided with a key block, and the locking sleeve 360 can only slide along the axial direction of the mounting cylinder 320 and cannot rotate relative to the mounting cylinder through the matching of the sliding groove and the key block, so that the locking sleeve 360 cannot rotate along with the rotating main shaft 132 when the frame 130 is locked.

In a modified embodiment, in order to reduce the overall equipment cost and the driving reliability, the actuating mechanism 340 includes a brake cable 341 and a brake spool 342, the brake cable 341 is movably inserted into the brake spool 342, one end of the brake cable 341 is connected with the locking sleeve 360, one end of the brake cable 341 close to the locking sleeve 360 is sleeved with a return spring 343, one end of the return spring 343 far away from the rear frame 130 is fixedly mounted on the mounting tube 350, and the other end of the return spring 343 is abutted to the end face of the corresponding end of the locking sleeve 360; the other end of the brake cable 341 penetrates through the brake cable pipe 342 and is connected with an operating handle 344; one end of the brake pipe 342 is fixed on the front frame 110, the other end of the brake pipe 342 is fixed on the mounting cylinder 350, and the return spring 343 can push the locking sleeve 360 tightly against the rotating main shaft 132. The operating handle 344 may be disposed on the handle bar, so that the driver can operate the operating handle easily. In the actual use process, the return spring 343 can tightly push the locking sleeve 360 against the rotating main shaft 132 in the natural state, so that the locking between the two can be realized. When the front frame 110 and the rear frame 130 need to be unlocked, a driver only needs to pull the brake cable 341 through the operating handle 344, so that the brake cable 341 drives the locking sleeve 360 to be away from the rotating main shaft 132 to release the rotating main shaft 132, and the return spring 343 is compressed at this time; when the front frame 110 and the rear frame 130 need to be locked, a driver only needs to operate the handle 344 to release the brake cable 341, and the locking sleeve 360 can automatically sleeve and tightly support the rotating main shaft 132 under the action of the return spring 343, so that the locking function is achieved.

Further, in order to improve the relative locking capability between the locking sleeve 360 and the rotating main shaft 132, a plurality of protrusions 138 or anti-slip patterns are arranged on the outer wall of one end of the rotating main shaft 132 close to the locking sleeve 360, and pits 361 matching the protrusions 138 or the anti-slip patterns are arranged on the inner wall of one end, corresponding to the locking sleeve 360. Of course, in some embodiments, the inner wall of the locking sleeve 360 may be provided with a quincunx groove, and the peripheral side of the outer wall of the rotating spindle 132 is provided with a plurality of protruding strips, which are in the shape of a quincunx to match the quincunx groove.

In addition, the design of brake cable 341 and brake spool 342 can be convenient for the wiring work of whole automobile body 100, and occupation of land space is little, is difficult to receive environmental impact simultaneously, improves the ability of cross-country use. The working principle of the brake cable 341 and the brake cable pipe 322 can refer to the brake cable structure of the conventional bicycle, and the application does not describe in detail, and refer to the structure in the split brake cable of patent CN 201921176508.1.

Referring to fig. 1, in order to facilitate that the whole vehicle body 100 does not affect the normal running of the vehicle body when running on a land, in an embodiment of the present application, further, one side of the balance pedal 131 is hinged to the connecting cage through a hinge, the balance pedal 131 can be folded around the hinge and attached to the connecting cage, and the connecting cage is provided with a limiting block 136 for limiting the swing range of the balance pedal 131. The hinged design of the balance pedal 131 can achieve a stowing function, reducing obstacles when driving on land. Meanwhile, the design of the limiting block 136 can facilitate limiting the swing of the balance pedal 131 when the driver drives in a water area, so that the limiting block 136 can provide a lateral force for the rear frame 130 when the driver leans, and meanwhile, the limiting block 136 occupies a smaller space relative to the balance pedal 131 when the driver drives on a land, so that the obstruction is reduced.

It should be added that, in the technical solution of the present application, since the rear frame 130 can rotate relative to the front frame 110, the swing requirements of the two are mainly used for turning when driving in water; when the vehicle runs on the land, the front wheels 120 and the rear wheels 140 on the whole vehicle body 100 are required to be on the same plane when the vehicle runs straight, so that when the vehicle runs from a water area to the land, the relative rotation between the rear frame 130 and the front frame 110 needs to be locked in advance through the locking device 300, and at the moment, the driver only needs to sit at the middle of the vehicle body 100 under normal conditions and ensure that the overall gravity centers of the vehicle body 100 and the driver are respectively coplanar, the rear frame 130 and the front frame 110 can be automatically aligned by utilizing the buoyancy of the two buoyancy of the buoyancy tank structure 200, and the whole alignment process is very simple and convenient. Such a design may allow vehicle body 100 to automatically yaw as it travels from the water to the road.

The above embodiments are only used for illustrating the technical solutions of the present invention and are not limited thereto, and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of the technical solutions of the present invention.
