In fig. 2, the front wheel carrier, the bogie and the rotating frame 10 are integrally fixed to each other (named as front part of the vehicle body), the fixing frame 9 is integrally fixed to the other (named as rear part of the vehicle body), and the front part of the vehicle body and the rear part of the vehicle body are rotatably connected through the rotating rod 12, so that the steering function of the vehicle body is realized.

Therefore, in the state of fig. 1, the fixing frame 9 and the rotating frame 10 need to be fixed to each other, while in the state of fig. 2, the fixing frame 9 and the rotating frame 10 need to be rotated to each other, so that the fixing frame 9 and the rotating frame 10 need to be in rotational butt joint, and simultaneously, locking is completed through the fixing frame 9 and the rotation when the fixing frame 9 and the rotating frame need to be fixed.

As shown in fig. 3 and 4, the third locking structure includes a third locking block 14 and a third locking port 15, the third locking port 15 is formed on the rotating frame 10, a third sliding port is formed on the fixed frame 9, the third locking block 14 is arranged in the third sliding port in a sliding manner, when the rotating frame 10 is turned to be collinear with the fixed frame 9, the third locking block 14 and the third locking port 15 are aligned with each other, and after the third locking block 14 is moved into the third locking port 15, the rotating frame 10 is limited in rotation relative to the fixed frame 9.

The third locking structure adopts the third locking block 14 and the third locking port 15, when the fixing frame 9 of the rotating frame 10 is collinear, the third locking block 14 and the third locking port 15 are aligned, then the rotating frame 10 can not rotate continuously relative to the fixing frame 9 when the third locking block 14 is inserted into the third locking port 15, that is, the limiting function is achieved, and the fixing frame 9 and the rotating frame 10 can be regarded as a whole after the limiting is completed.

As shown in fig. 2 and 3, the height of the transverse frame 2 is higher than that of the vertical frame, an embedding opening 18 is laterally formed in the vertical frame, the first locking structure comprises a first locking block 16 and a first locking opening 17, a first sliding opening and a first locking opening 17 are respectively formed in the front-back direction (the lateral direction is the left-right direction and the front-back direction is the left-right direction is the horizontal direction is vertical), the first locking block 16 is arranged in the sliding opening in the sliding manner, when the vertical frame 1 is turned to be parallel to the vertical frame, the front wheel frame 3 close to one side of the vertical frame moves into the embedding opening 18, after the first locking block 16 slides outwards, the outer end portion of the first locking block 16 is inserted into the first locking opening 17, and when the first locking block 16 is inserted into the first locking opening 17, two sides of the front wheel frame 3 are respectively attached to the first locking block 16 and the inner end surface of the embedding opening 18 of the vertical frame, so that limiting locking is completed.

In the above description, the front wheel support and the rear wheel support are fixed to each other (that is, the manner in which the cross frame 2 and the vertical frame are fixed to each other), in the process of switching from fig. 1 to fig. 2, the first locking block 16 is first required to be retracted to expose the side surface of the insertion opening 18, then the cross frame 2 is turned over, the front wheel frame 3 on one side of the cross frame 2 is moved into the insertion opening 18, then the first locking block 16 is pushed back into the first locking opening 17, at this time, both sides of the front wheel frame 3 located in the insertion opening 18 are blocked by the first locking block 16 and the vertical frame, and thus the limit function is completed, since one front wheel frame 3 on the cross frame 2 is already fixed by the vertical frame, the vertical frame 1 on which the cross frame 2 is located is also fixed with respect to the vertical frame, and after the front wheel assembly on the front wheel frame 3 is removed or lifted, this corresponds to switching from the three-wheel mode of fig. 1 to the two-wheel mode of fig. 2.

Of course, the third locking piece 14 is also withdrawn from the third locking opening 15 during the switching process, so that the fixing frame 9 and the rotating frame 10 can rotate relative to each other.

As shown in fig. 6 and 7, the second locking structure includes a clamping block 19 fixedly arranged on the adjusting rod 7 and a clamping groove formed in the side wall of the adjusting hole 4 of the vertical frame 1, the clamping block 19 is located in the clamping groove, the clamping groove includes an arc-shaped groove 20 horizontally arranged and two locking grooves 21 respectively vertically butted at two ends of the arc-shaped groove 20 downwards, the radial angle of the arc-shaped groove 20 is 90 degrees, the size of the locking groove 21 is consistent with that of the clamping block 19, so that the clamping block 19 can only move in the direction towards the arc-shaped groove 20 after being located in the locking groove 21, and the clamping block 19 can move in the arc-shaped groove 20.

The above mentioned fixed direction of the handle bar 8 relative to the upright post also needs to be changed correspondingly after the mode is switched, and the adjusted angle is necessarily 90 degrees, so that the adjusted direct direction is guaranteed not to deviate, so the design adopts the design that the clamping block 19 is arranged in the clamping groove, the clamping groove is designed into a part of arc-shaped groove 20 to limit the clamping block 19 to move within the range of 90 degrees, and the locking groove 21 is used to provide two extreme points for arranging the clamping block 19, so that the limit after the two modes are switched completely is realized.

In addition, when the first locking structure, the second locking structure and the third locking structure are adjusted to the extreme positions at two ends, the first locking structure, the second locking structure and the third locking structure are positively locked to effectively improve the reliability, and the first locking structure, the second locking structure and the third locking structure are in various forms aiming at locking functions, so that the feasibility of the first locking structure, the second locking structure and the third locking structure is demonstrated by taking the following examples as examples: the simplest mode can adopt a friction principle, the parts have large friction force, except for external force, namely interference force generated by manual operation in the adjustment process, the friction force between the two parts cannot lead the parts to deviate from the extreme value position, but the friction principle still has certain strength defect; therefore, screw holes can be drilled at extreme positions at two ends, and then the two parts can be locked at the extreme positions in a mode of fixing bolts and nuts, but the operability is complex; or the two extreme values are additionally provided with the magnetic iron magnet blocks, so that the two parts generate certain adsorption force through the magnetic principle under the condition of not being subjected to external force and being positioned at the extreme value position, and the two parts are not easy to separate from the extreme value position so as to realize the self-locking function.

In summary, if a certain part has a movable range relative to another part, and if the movable range has at least two extreme points, the two extreme points can be locked with each other on the premise that the two extreme points are designed, and the locking strength of the two parts can be different according to different practical use requirements.

The frame assembly bottom still activity is equipped with side stabilizer blade and two-way stabilizer blade that can play the supporting role to the tricycle of falling under the two-wheeled mode after turning over, forms the tripod supporting function to the tricycle of falling between side stabilizer blade, rear wheel subassembly and the front wheel subassembly three of a set of, and the both sides of two-way stabilizer blade and rear wheel subassembly form the tripod supporting function to the tricycle of falling when two-way stabilizer blade turns over.

The design function of the side support leg and the two-way support leg is the design function of the support leg of the electric vehicle and the motorcycle on the market, the side support leg has the function of supporting the vehicle body to avoid the vehicle from tilting when the vehicle is parked, the two-way support leg belongs to the heavy support leg, the function is to erect the whole vehicle body, at the moment, the two-way support leg and the rear wheel of the vehicle body form three points for supporting the whole vehicle body, the vehicle body can be used for assembling and maintaining the vehicle body after being erected, the function is particularly important in the invention, because the whole vehicle body is firstly required to be erected in the switching operation process of the three-wheel mode and the two-wheel mode, and the operation of the first locking structure, the second locking structure and the third locking structure can be manually completed.
