[0002] The rise of multi-story parking garages in the prior art has solved the problem of limited parking spaces, but the ensuing problem is that electric vehicles cannot satisfy the requirements of parking and charging at the same time.

[0003] Chinese patent publication number CN 116714455A, entitled "Three-dimensional parking garage with charging function", discloses that: the transmission mechanism includes multiple transmission units, the transmission unit includes a chain driving plate, chain plates respectively connected to both sides of the chain driving plate, and multiple chain plates connected to the chain plate, adjacent transmission units are connected end to end to form a complete transmission mechanism, the chain driving plate is trapezoidal, and the chain driving plate and the chain plate are located at the acute angle of the chain driving plate.

[0004] In the above technical solution, the transmission mechanism, the guide mechanism and the power-taking mechanism are all located in the main track, so that in order to ensure that the vehicle-carrying plate in the vehicle-carrying mechanism has sufficient operating space, the main track requires a large space width and height, so that the overall site and space occupied by the garage are relatively high, and the oil required for the chain operation will also cause safety hazards to the power-taking mechanism. Utility Model Content

[0005] The utility model aims to overcome the deficiencies in the prior art and provide a steering mechanism and a three-dimensional parking garage.

[0006] The technical solution of the utility model is as follows:

[0007] The steering mechanism includes a roller chain and a plurality of steering assemblies evenly distributed and mounted on the roller chain, wherein the steering assembly includes a driving arm plate with a driving slider mounting hole opened at one end, a bogie, a spherical bearing, and a cantilever shaft passing through the bogie, the driving slider mounting hole and the spherical bearing in sequence, and the other end of the driving arm plate is respectively connected to the roller chain.

[0008] The above-mentioned bogie includes a bogie body composed of a base and a wing plate arranged in parallel and a connecting column connecting the base and the wing plate, a plurality of running wheel axles passing through the base in parallel, running wheels installed at both ends of the running wheel axles, guide wheels placed between the base and the wing plate, and a plurality of guide wheel axles parallel to and arranged perpendicular to the running wheel axles and passing through the base, guide wheels and wing plates in sequence.

[0010] The cantilever shaft is engaged in the driving slider installation hole through the driving slider, and the driving slider is located between the spherical bearing and the bogie body.

[0011] Furthermore, it also includes an electric slip ring axially passing through the cantilever shaft.

[0012] A current collector is axially inserted into the bottom of the cantilever shaft, and the current collector runs in the box-type busbar.

[0013] The three-dimensional parking garage comprises a steering mechanism, a track mechanism for the steering mechanism to operate, a driving mechanism for driving the steering mechanism to operate in the track mechanism, and a vehicle carrying mechanism operating together with the steering mechanism.

[0014] The above-mentioned vehicle-carrying mechanism includes a vehicle-carrying plate and a vehicle-carrying back plate connected to one end of the vehicle-carrying plate by a hinge, and the side surface of the vehicle-carrying plate and the side surface of the vehicle-carrying back plate are respectively fixed and maintained vertically by the two ends of a plurality of inclined rods; a skateboard is installed on the back of the vehicle-carrying back plate, and a balance wheel is installed on the skateboard; an axial sleeve is installed on the cross beam of the vehicle-carrying back plate, and the sleeve is used to engage with a spherical bearing, and the spherical bearing is locked by an end cover plate; an H-shaped bracket is fixedly installed on the top of the vehicle-carrying back plate, and a buffer pad is fixed on the top of the H-shaped bracket; a charging pile is also installed on the vehicle-carrying back plate.

[0015] The track mechanism comprises a roller chain track for the roller chain to run, a main track for the bogie to run, and an auxiliary track for the balance wheel of the vehicle carrying mechanism to run.

[0017] The beneficial effects of the utility model are as follows: the utility model separates the roller chain track operated by the roller chain from the main track operated by the bogie, and drives the steering assembly through the driving arm plate. Compared with the prior art, the length of the main track can be made shorter, the width can be made narrower and the depth can be made shallower, so that the overall occupied area of ​​the parking garage is reduced and the occupied space is smaller; in addition, since the running track of the bogie and the running track of the roller chain are not in the same track, resulting in different angular velocities, the vehicle loading plate can quickly pull away from other vehicle loading plates that have not yet entered the curve at a faster speed when passing through the arc of the main track to avoid collision with adjacent vehicle loading plates; in addition, the running surface of the slide plate of the auxiliary track and the back plate of the vehicle loading plate is higher than the running surface of the steering mechanism of the main track, which means that the main track and the auxiliary track run in layers without interfering with each other, so it is beneficial to the synchronous layout of the auxiliary track relative to the main track, and the narrower main track can connect more auxiliary tracks, which is beneficial to the balance and smooth operation of the vehicle loading mechanism.

[0040] In order to better illustrate the present invention, further description will be given in conjunction with embodiments and drawings.

[0041] Example 1

[0042] like Figures 1 to 14 As shown, the steering mechanism 1 includes a roller chain 12 and a plurality of steering assemblies 11 evenly distributed and mounted on the roller chain 12. The steering assembly 11 includes a driving arm plate 113 with a driving slider mounting hole 119 at one end, a bogie 111, a spherical bearing 112, a cantilever shaft 118 passing through the bogie 111, the driving slider mounting hole 119 and the spherical bearing 112 in sequence, and the other end of the driving arm plate 113 is connected to the roller chain 12 respectively.

[0043] Specifically, the bogie 111 includes a bogie body 1111 consisting of a base 11111 and a wing plate 11113 arranged in parallel and a connecting column 11112 connecting the base 11111 and the wing plate, a plurality of running wheel axles 1112 passing through the base 11111 in parallel, running wheels 1113 installed at both ends of the running wheel axles 1112, a guide wheel 1115 placed between the base 11111 and the wing plate 11113, and a plurality of guide wheel axles 1114 arranged in parallel and perpendicular to the running wheel axles 1112 and passing through the base 11111, the guide wheel 1115 and the wing plate 11113 in sequence.

[0044] Specifically, the spherical bearing 112 includes a sphere 1121 with a sphere mounting hole axially opened, an upper sphere sleeve 1122 and a lower sphere sleeve 1123 respectively sleeved on the outside of the sphere 1121, a first tapered roller bearing 1124 and a second tapered roller bearing 1125 sleeved on the cantilever shaft 118 and located in the sphere mounting hole 11212 in sequence, and a tightening nut 116 fixing the spherical bearing 112 on the cantilever shaft 118. The high-tightening nut 116 serves to tighten the second tapered roller bearing 1125, thereby fixing the spherical bearing 112 on the cantilever shaft 118, ensuring that the vehicle carrier 4 reduces the rotational friction resistance of the steering assembly 11 during the cornering and steering, and that the spherical bearing 112 provides good centripetal force during the movement of the vehicle carrier 4, so as to ensure the smooth operation of the vehicle carrier 4; after the tightening nut 116 is installed, the driving slider 115 and the driving arm plate 119 are also fixed between the spherical bearing 112 and the bogie 111. An oil groove 11211 is formed on the outer periphery of the ball 1121 , and lubricating oil is injected from the upper ball sleeve 1122 into the oil groove 11211 to reduce the friction between the ball 1121 and the upper ball sleeve and the lower ball sleeve 1122 .

[0045] Furthermore, the cantilever shaft 118 is engaged in the drive slider mounting hole 119 through the drive slider 115, and the drive slider 115 is located between the spherical bearing 112 and the bogie body 1111. It also includes an electric slip ring 117 that axially passes through the cantilever shaft 118, and the electric slip ring 117 plays a role in preventing tangling during the transmission of electricity. A collector 114 is axially inserted into the bottom of the cantilever shaft 118, and the collector 114 runs in the box-type busbar 13.

[0046] Example 2

[0047] like Figures 1 to 14 As shown, the three-dimensional parking garage includes a steering mechanism 1, a track mechanism 2 for the steering mechanism 1 to operate, a driving mechanism 3 for driving the steering mechanism 1 to operate in the track mechanism 2, and a vehicle carrying mechanism 4 that operates together with the steering mechanism 1.

[0048] Specifically, the vehicle-carrying mechanism 1 includes a vehicle-carrying plate 41 and a vehicle-carrying back plate 42 connected to one end of the vehicle-carrying plate 41 by a hinge 44. The side surfaces of the vehicle-carrying plate 41 and the side surfaces of the vehicle-carrying back plate 42 are respectively fixed and maintained at both ends of a plurality of inclined tie rods 43 to be vertically arranged on the vehicle-carrying back plate 42; a slide plate 49 is installed on the back of the vehicle-carrying back plate 42, and a balance wheel 48 is installed on the slide plate 49; an axial sleeve 47 is installed on the cross beam of the vehicle-carrying back plate 42, and the sleeve 47 is used to engage with the spherical bearing 112, and the spherical bearing 112 is locked by the end cover plate 422; an H-shaped bracket 45 is fixedly installed on the top of the vehicle-carrying back plate 42, and a buffer pad 46 is fixed on the top of the H-shaped bracket 45. The H-shaped bracket 45 is close to or close to the vehicle-carrying mechanism above the vehicle-carrying mechanism 1 during operation to prevent the vehicle-carrying mechanism 1 from falling and hitting the car parked by the vehicle-carrying mechanism 1; a charging pile 421 is also installed on the vehicle-carrying back plate 42 to meet the charging safety problem of the charging car.

[0049] Specifically, the track mechanism 2 includes a roller chain track 23 for the roller chain 12 to run, a main track 21 for the bogie 111 to run, and an auxiliary track 22 for the balance wheel 48 of the vehicle carrying mechanism 1 to run; the roller chain track 23 is arranged on the inner ring of the main track 21, and the box-type busbar 13 is fixed at the bottom of the main track 21 and the opening faces the opening of the main track 21.

[0050] Specifically, the driving mechanism 3 includes a reduction motor 31, a small sprocket 32 ​​installed on the output shaft of the reduction motor 31, a large sprocket 34 rotating with the small sprocket 32, a transmission chain 33 connecting the small sprocket 32 ​​and the large sprocket 34, a transmission main shaft 37 passing axially through the large sprocket 34, and a driving chain fork 38 mounted on the transmission main shaft 37, which respectively supports the first bearing seat 35 and the second bearing seat 36 at both ends of the transmission main shaft 37; the driving chain fork 38 drives the roller chain 12 to move. The roller chain 12 drives the bogie 111 in the steering assembly 11 to run in the main track 21, and the auxiliary tracks 22 are distributed on both sides of the main track 21, namely the left and right auxiliary tracks and the upper and lower auxiliary tracks; the groove surface of the auxiliary track 22 is in sliding contact with the slide plate 49 on the back side 42 of the vehicle loading plate, especially the lower slide plate, which serves to support and drag the vehicle loading plate and reduce the running resistance and running noise; the middle groove of the auxiliary track 22 serves to accommodate the balancing wheel 48 behind the back plate of the vehicle loading plate. Since the auxiliary track 22 is distributed relative to the main track 21, the running trajectory of the cantilever shaft 118 of the bogie 111 running in the main track 21 is synchronous with the auxiliary track 22, so the movement of the cantilever shaft 118 of the bogie 111 is equivalent to the synchronous operation of the balancing wheel 48, and the balancing wheels 48 on both sides of the back plate 42 of the vehicle loading plate are synchronously turned on the left and right and upper and lower auxiliary tracks 22 respectively, so they can play a horizontal role, thereby ensuring the smooth and balanced operation of the vehicle loading plate 4 in the case of a single-sided suspension vehicle loading mechanism 4.
