technical field

The invention relates to a three-dimensional garage.

Background technique

With the continuous growth of automobile consumption, the difficulty of parking in cities has become a thorny problem faced by various places. The establishment of three-dimensional garages is an effective way to solve the static traffic in cities. The three-dimensional garage generally includes a multi-storey garage frame, and each layer of the garage frame is provided with a plurality of parking spaces, and the garage frame is also provided with a carrier that can reciprocate along the garage frame to access the vehicle. When the carrier walks along the rails to the designated parking space, it needs to stop at the designated position accurately to prevent the vehicle storage position from seriously deviating from the center of the parking space and causing safety hazards. However, since the friction between the carrier and the track is not a constant value, the carrier will always continue to move forward for a certain distance under the action of inertia after the driving power source of the carrier is turned off. Therefore, this distance needs to be limited to ensure that the carrier can be accurately Stop at the designated position.

Detailed ways

The embodiment of three-dimensional garage of the present invention:

The concrete structure of the three-dimensional garage of the present invention is as shown in Figure 1 to Figure 5, comprises garage frame 1 and carrier, and garage frame 1 is provided with two tracks 2 along it for carrier to walk in parallel on the garage frame 1, and carrier includes carrier The device body 3 and the driving part 4 used to drive the movement of the carrier body 3, the rack 5 parallel to the track 2 is fixed on the garage frame 1, and the lower end of the carrier body 3 is provided with a gear 6 for meshing with the rack 5 , the gear 6 is in transmission connection with the driving part 4, and the driving part 4 has a holding function so that the output shaft of the driving part cannot be rotated in a stop state. The driving part 4 with holding function can be a motor with mechanical brake, a motor with electromagnetic brake or a servo brake motor. Both sides of the carrier body 3 in the width direction are provided with the gears 6 , and correspondingly, the racks 5 are provided at positions corresponding to the two rails 2 on the garage frame 1 .

The upper end surface of the rail 2 forms a supporting surface for supporting the carrier body 3, and the rack 5 is fixed on the side (that is, the outer side) of the two rails 2 away from each other, and the toothed surface for meshing with the gear 6 is set On the upper surface of the rack 5, and the toothed surface is not higher than the upper end surface of the track 2. When the carrier body 3 is walking along the track 2 , the gear 6 is engaged with the rack 5 and rolls on the rack 5 .

The power transmission mode of the driving part 4 to the gear 6 is as follows: the top of the carrier body 3 is rotated to be provided with a transmission shaft 7, and the lower end of the carrier body 3 is provided with a road wheel 8, and the shape of the road wheel 8 matches the shape of the track 2 to follow the track 2. walk. The gear 6 on the corresponding side is fixed on the outer end of the road wheel shaft that rotates synchronously with the road wheel 8, and the inner end of the road wheel shaft is also fixed with a driven wheel 10. The transmission shaft 7 extends along the width direction of the carrier body 3, the two ends of the transmission shaft 7 are fixed with driving wheels 9, the driving wheels 9 are located directly above the corresponding driven wheels 10, and the driving wheels 9 provide power to the driven wheels 10 through the transmission structure . The transmission structure can be any transmission structure capable of transmitting power between the driving wheel 9 and the driven wheel 10 such as a transmission belt, a transmission chain or a right-angle commutator. Corresponding side gear 6 is fixed on the driving wheel shaft that rotates synchronously with driving wheel 9, so road wheel 8 and gear 6 can rotate synchronously with driven wheel 10 when driving wheel 9 rotates. The rotation of the walking wheel 8 will drive the carrier body 3 to walk along the track 2, and the rotation of the gear 8 will mesh with the rack 5 and roll on the rack 5. After the carrier moves to the specified position, the driving part 4 stops, and the power of the carrier to continue to slide forward will be absorbed by the friction force between the output shaft of the driving part 4 and the rack and pinion, thereby limiting the sliding of the carrier and making it The carrier can accurately park at the set position. In addition, thanks to the inherent high transmission accuracy of the rack and pinion, the running distance of the carrier is always equal to the distance turned by the gear 6, which is beneficial to accurately record the travel of the carrier.

The arrangement of the transmission system between the driving part 4 and the gear 6 can ensure that the interior of the carrier is a hollow structure, which will not affect the vehicles to be accessed and pass through the frame of the carrier, and can also ensure that the driving wheels 9 on both sides move simultaneously.

In order to prevent the tooth jumping phenomenon between the rack and pinion when the carrier is moving, the lower end of the carrier body 3 is rotated with a roller 11. The roller 11 is located below the rack 5, and the lower end surface of the rack 5 is parallel to the guide surface of the track 2. flat. Under normal conditions, there is a gap between the roller 11 and the lower end surface of the rack 5, so that no frictional force will be generated between the roller 11 and the rack 5 when the carrier is moving, reducing the moving resistance of the carrier. At the same time, the gap between the roller 11 and the lower end surface of the rack 5 is smaller than the overall height of the teeth of the rack 5, so when there is a tooth skipping tendency, the roller 11 will contact the lower end surface of the rack 5 first, thereby avoiding the occurrence of tooth skipping. The roller 11 is rotatably arranged at the lower end of the carrier body 3, so after the roller 11 contacts the rack 5, it is in the form of rolling friction with the rack 5, which can reduce the running resistance of the carrier in this state.

In other embodiments, the roller can also be replaced by a block fixed on the carrier body, as long as there is a gap less than the full height of the rack teeth between the upper end surface of the block and the lower end surface of the rack; the roller can also be omitted, At this time, there is no need to make any requirements on the shape of the lower end of the rack, but in this state, the carrier does not have the function of anti-jumping teeth; in the absence of rollers, the guide surface of the track can also be set on the side of the track. The upper end surface of the track may not be used to form a support surface; the track may not be arranged on the track, but directly fixed on the garage frame; it is also possible to set only one track in the middle, and only one set of gears is required correspondingly at this time Rack meshing structure.

In this embodiment, the lower end of the carrier body 3 is rotatably provided with a guide wheel 12. The center line of the guide wheel 12 extends along the vertical direction. scroll. In this case, when the carrier travels along the track 2, the carrier will not move in its own width direction, which can ensure the smooth progress of the carrier. Certainly, in other embodiments, the guide wheel can also be omitted, but the traveling wheel is made into a form with double rims to prevent the carrier from moving in the width direction.
