As shown in fig. 4, two sets of the slide rails 62 and the slide blocks 63 that cooperate with each other are symmetrically disposed between the mounting portion 2 and the third side walls 612 of the slide frame 61 in the axial direction of the rotation shaft 5, respectively, that is, each of the third side walls 612 is connected to the mounting portion 2 by the slide rails 62 and the slide blocks 63. In this embodiment, the sliding rail 62 is installed on one side of each third side wall 612 facing the installation portion 2, correspondingly, the sliding blocks 63 are provided on the corresponding positions of the installation portion 2, the installation portion 2 and the sliding frame 61 can slide relatively through the cooperation of the sliding rail sliding blocks, and the sliding connection between the installation portion 2 and the sliding frame 61 is realized by using the two groups of sliding rails 62 and the sliding blocks 63, so that the stability of the connection between the installation portion 2 and the sliding frame 61 is improved. In other embodiments, the mounting positions of the slide rail 62 and the slider 63 may be interchanged, that is, the slider 63 is mounted on the third sidewall 612 and the slide rail 62 is mounted on the mounting portion 2. Further, the two sets of sliding rails 62 and the sliding blocks 63 are respectively arranged at the left side and the right side of the sliding frame 61, and the heights of the two sets of sliding rails 62 and the sliding blocks 63 in the vertical direction are set to be the same, so that on one hand, the stress is uniform during sliding, thereby being beneficial to further improving the stability during sliding, and if the sliding rails 62 and the sliding blocks 63 are arranged at the upper side and the lower side of the sliding frame 61, the stress eccentricity condition may occur, and the stable sliding is not beneficial to being ensured; on the other hand, the reasonable layout of the traveling assembly mounting mechanism 100 is also facilitated, so that the layout compactness can be improved while the sliding connection is satisfied.

In the present embodiment, the mounting portion 2, the slide frame 61, and the traveling body 1 are sequentially sleeved, thereby contributing to improvement in layout compactness of the traveling assembly mounting mechanism 100 and reduction in the size of the entire apparatus. Wherein, clearance assemblies are respectively arranged between the mounting part 2 and the sliding frame 61 and between the sliding frame 61 and the walking body 1, specifically, a second preset clearance 23 is arranged between at least two third side walls 612 of the sliding frame 61 and the walking body 1, and the size of the second preset clearance 23 should be determined according to the rotation requirement of the walking body 1 so as to ensure that the walking body 1 does not interfere with the mounting part 2 in the process of adjusting the posture by rotating. In one embodiment, the second preset gap 23 is the same as the first preset gap 22, so that the entire structure of the walking body is compact.

In another embodiment, when the running gear installation assembly of embodiment 1 and embodiment 2 are respectively provided on the running gear main body 1, the installation parts 2 may be set to be identical in size, and the parts are standardized to facilitate the production process, in which case the first preset gap 22 is set to be larger than the second preset gap 23. In another embodiment, as shown in fig. 10, 12 and 13, the walking assembly mounting mechanism 100 further includes a third stopping assembly 7, where the third stopping assembly 7 is disposed between the walking body 1 and the sliding frame 61 and has a locked state and an unlocked state, and is used to lock or unlock the relative rotation state between the walking body 1 and the walking assembly mounting mechanism 100, respectively, so that the rotating assembly 3 can be locked when the power conversion device 200 moves, and the sliding frame 61 cannot rotate relative to the walking body 1, so that the power conversion device 200 is smoother when moving and does not shake due to the rotating assembly 3. When the battery replacing device 200 needs to be aligned with the electric vehicle, the rotating assembly 3 is unlocked to enable the battery replacing device 200 to rotate relatively, so that the battery replacing device 200 can be twisted relatively to be aligned with the electric vehicle to facilitate the disassembly and assembly of the battery.

Specifically, the sliding frame 61 has a second preset gap 23 between the front and rear sides along the walking direction and the walking body 1, the third stop assembly 7 includes a telescopic wedge block 71, and when the third stop assembly 7 is in the locked state, the wedge block 71 extends from the original position into the second preset gap 23 to limit the relative rotation of the sliding frame 61 and the walking body 1; when the third stopper assembly 7 is in the unlocked state, the wedge 71 is retracted to the original position to release the second preset gap 23, the second preset gap 23 allows it to have a degree of freedom of rotation, the third stopper assembly 7 is disposed at the both side positions, the telescopic wedge 71 is adopted, the narrower end of which faces the second preset gap 23 between the slide frame 61 and the traveling body 1, in the locked state, the wedge 71 is protruded to be caught in the second preset gap 23 between the slide frame 61 and the traveling body 1, so that there is no degree of freedom of rotation between the slide frame 61 and the traveling body 1, rotation is impossible, and in the unlocked state, the wedge 71 is retracted to the original position to release the second preset gap 23, and the rotation assembly 3 can rotate. In the present embodiment, the wedge 71 is driven to expand and contract by the cylinder to achieve switching between the locked state and the unlocked state. In other embodiments, the wedge 71 may be driven to retract in other ways. In the present embodiment, the first stopper assembly 8 is similar in structure to the third stopper assembly 7.

Further, the traveling assembly mounting mechanism 100 further includes a second stopper assembly (not shown in the drawings) provided on the sliding assembly 6 and having a locked state and an unlocked state for locking or unlocking the relative sliding state between the traveling body 1 and the traveling assembly mounting mechanism, respectively. The second stop component can limit the relative movement of the sliding component 6 when in a locking state, so that the walking component mounting mechanism 100 is fixed relative to the walking body 1 when the walking wheel 4 is driven, and the walking body 1 keeps a posture relative to the walking direction and walks; the sliding assembly 6 is relatively movable when the second stopper assembly is in the unlocked state, so that the traveling assembly mounting mechanism 100 is slidable with respect to the traveling body 1 when the traveling wheel 4 is driven, whereby the traveling body 1 adjusts the posture with respect to the traveling direction. That is, when the traveling body 1 travels to the electric vehicle along the traveling direction defined by the guide rail 201, the second stopper assembly is in the locked state, that is, the sliding rail 62 and the sliding block 63 of the sliding assembly 6 cannot slide relatively, so that the traveling body 1 cannot shake due to the sliding of the sliding assembly 6 during the previous traveling, thereby improving the stability of the traveling body 1 during traveling; after the traveling body 1 travels below the electric vehicle, the second stopper assembly is then changed to an unlocked state, so that the slide rail 62 and the slider 63 can slide relatively, and the relative angle between the traveling body 1 and the electric vehicle is further adjusted.

Wherein, in the course of the traveling body 1 traveling to the electric vehicle along the traveling direction defined by the guide rail 201, the two traveling wheels 4 located at the front side or the rear side along the traveling direction are driven at the same speed; in the present embodiment, when the posture of the traveling body 1 is adjusted after traveling under the electric vehicle, one of the two traveling wheels on the front side or the rear side is fixed and only the other traveling wheel 4 is driven. In other embodiments, the two road wheels 4 on the front or rear side may be driven at a differential speed.

In one embodiment, the second stop assembly includes a retractable stop rod that extends from the home position and abuts and compresses the slide rail 62 in a predetermined position to limit the relative movement of the slide rail 62 and the slide block 63 when the second stop assembly is in the locked state; when the second stopper assembly is in the unlocked state, the stopper rod is retracted to the original position, and by setting the stopper rod to be telescopic, the switching of the locked state and the unlocked state of the second stopper assembly is achieved, and thus, the control of whether the slide assembly 6 can slide is achieved. Wherein the stop rod is pushed out of the pressing slide rail 62 to prevent the sliding block 63 from sliding relative to the slide rail 62 by friction force.

There are two stop bars, the expansion and contraction direction of which points to the side face of the slide rail 62, that is, the stop bars respectively extend from above and below the slide rail 62 and respectively abut against the upper surface and the lower surface of the slide rail 62. With this arrangement, the two stop bars act on the slide rail 62 from opposite sides of the slide rail 62, respectively, so that the two stop bars can clamp the slide rail 62 during the stop process, so that the friction force is greater and the stop effect is better. Further, the upper and lower surfaces of the slide rail 62 may be configured to be at least partially inwardly recessed, with the corresponding end shape of the stop bar mating with the inwardly recessed shape of the upper and lower surfaces of the slide rail 62. The shape of the end part of the stop rod is matched with the shape of the side surface of the slide rail 62, so that the stop rod is matched with the slide rail 62 more firmly, the stop effect of the stop rod is further improved, and the situation that a gap exists between the stop rod and the side surface of the slide rail 62 or the stop rod is separated from the slide rail 62 is avoided.

In another embodiment, the second stop assembly comprises a telescopic stop pin, the sliding rail 62 is provided with a corresponding pin hole, and when the second stop assembly is in a locking state, the stop pin extends from the original position and is locked in the pin hole only to limit the relative movement of the sliding rail 62 and the sliding block 63; when the second detent assembly is in the unlocked state, the detent pin is retracted to the home position. By providing the retaining pin to be telescopic, the switching of the locked and unlocked state of the second retaining assembly is also achieved, as is the control of whether the sliding assembly 6 can slide. At the same time, the cooperation of the stop pin and the pin hole enables the second stop assembly to have higher limiting reliability on sliding.
