Description

Technical Field

[0001] The invention relates to a stereoscopic garage, in particular to a stereoscopic garage with simple structure and low cost. Background Art

[0002] With the popularity of cars, every family will have a car in the future. The large number of cars in cities will cause road traffic congestion. Traditional ground parking lots and underground parking garages can only use the space close to the ground, and the number of parking spaces that can be set is very small. The upper space on the same floor cannot be used, resulting in space waste and low utilization rate. It is increasingly unable to meet demand, and the problem of parking difficulties is becoming more and more prominent. Therefore, it is imperative to build more stereo garages.

[0003] The existing three-dimensional garage is a vertical lifting mechanical parking device, which uses a transverse shifting device to transfer the vehicle between the parking space and the elevator to achieve the purpose of parking or picking up the car. However, the structure of the existing transverse shifting device is very complicated. It is designed by designing four motors to independently power and independently drive the wheels to roll, so as to make the entire transverse shifting device move horizontally to achieve the transfer between the parking space and the elevator. If one motor is used to drive the four wheels to move, since the transverse shifting device needs to cross the vertical support beam of the elevator shaft when moving from the parking space to the elevator, the single motor drive form will be powered off at the moment when the transverse shifting device crosses the vertical support beam, so that the driving force is interrupted and it cannot reach the elevator. However, if four motors are used to drive, the front and rear wheels can both drive the transverse shifting device to move, and this problem does not exist. However, the form of four motors driving four wheels to roll will cause more drives, complex structure, high requirements on the overall strength of the garage, and difficult control, resulting in high failure rate and poor stability. Therefore, the existing use of four drive motors to drive cannot effectively simplify the structure, has high production costs, and is not conducive to popularization and application. Summary of the invention

[0004] The object of the present invention is to provide a three-dimensional car park with simple structure and low cost.

[0005] In order to achieve the above-mentioned purpose, the three-dimensional parking garage provided by the present invention includes a lifting shaft, a parking garage, a comb-tooth mechanism, an elevator and a comb-tooth transverse movement device; the parking garages are arranged on opposite sides of the lifting shaft, and the parking garages located on the same side are stacked up and down; the comb-tooth mechanism is arranged in the lifting shaft in a vertically sliding manner; the elevator is arranged in the lifting shaft and drives the comb-tooth mechanism to rise and fall; the comb-tooth transverse movement device is arranged in each of the parking garages, and can move laterally between the corresponding parking garage and the lifting shaft, so that the vehicle can be transferred between the comb-tooth mechanism and the parking garage; the comb-tooth transverse movement device includes a sliding contact mechanism, which includes at least two slides and at least two sliders, and the slides are respectively provided on the side of the parking garage and the side wall of the lifting shaft corresponding to the horizontal position; at least one slider is slidably matched with one of the slides and is in conductive contact with it, so as to ensure that the comb-tooth transverse movement device can be continuously powered when it moves.

[0006] Compared with the prior art, the present invention sets a slide seat on the side of the parking garage and the side wall of the lift shaft corresponding to the horizontal position, and then sets two sliders separated from each other by a certain distance; when the comb-tooth transverse moving device moves from the parking garage to the lift shaft, the front slider leaves the slide seat on the parking garage, but the rear slider is still on the slide seat of the parking garage; and before the rear slider leaves the parking garage, the front slider is in electrical contact with the slide seat on the lift shaft, so that at least one slider can slide and cooperate with one of the sliders and make conductive contact, so as to ensure that the comb-tooth transverse moving device can continuously obtain power supply when it moves, avoiding the situation where the motor is powered off. Therefore, the comb-tooth transverse moving device can drive all rollers to move synchronously with a single motor, avoiding the traditional method of using four motors to drive each roller to move separately, reducing the drive by three quarters, greatly simplifying the structure of the comb-tooth transverse moving device, thereby reducing the overall strength requirements of the garage, making the control simpler and more convenient, reducing the failure rate of the equipment, improving stability, effectively reducing production costs, and facilitating wide application.

[0007] Preferably, the comb tooth transverse movement device also includes a bracket, a roller, a first comb tooth and a driving mechanism, the rollers are respectively arranged at both ends of the bracket, the first comb teeth are arranged on the bracket for the wheels of the vehicle to bear, and the first comb teeth and the comb teeth of the comb tooth mechanism are staggered; the output end of the driving mechanism is connected to the roller to drive the rollers at both ends of the bracket to move synchronously.

[0008] Specifically, the first comb teeth include first front comb teeth and first rear comb teeth, the first front comb teeth are arranged on both sides of the front section of the bracket, and the first rear comb teeth are arranged on both sides of the rear section of the bracket.

[0009] Specifically, the bracket includes a crossbeam and a longitudinal beam, the crossbeam is arranged at both ends of the longitudinal beam, and the roller is arranged on the outer side of the crossbeam.

[0010] Specifically, the driving mechanism includes a motor, a pair of gear chain groups and a linkage shaft. The motor and the gear chain group are arranged on the bracket. The output end of the motor drives the linkage shaft to rotate. The linkage shaft is respectively connected to the two gear chain groups; the gear chain group is connected to the roller at the end of the bracket.

[0011] Specifically, the height of the bearing surface of the first comb teeth is lower than the height of the bearing surface of the bracket, so that the bracket bears the chassis of the vehicle, and the first comb teeth bear the wheels of the vehicle. In this way, most of the weight of the vehicle can be borne by the bracket, and the first comb teeth only bear the weight of the wheels, which greatly reduces the structural strength requirements of the first comb teeth. Therefore, the structure of the first comb teeth can be simplified and the amount of steel used in the first comb teeth can be reduced. In addition, the first comb teeth can also prevent the wheels of the vehicle from sagging excessively, thereby saving and reducing the floor height of a single-story parking garage and improving the utilization rate of space.

[0012] Specifically, the slide seat includes a seat body, a plurality of slide grooves are provided on the seat body, a conductive busbar is provided in the slide grooves, and a plurality of conductive contact heads are provided on the slide head, and the ends of the contact heads are slidably matched with the slide grooves one by one and electrically contacted with the busbar. By providing the slide grooves and contact heads, the slide head and the slide seat can be connected both slidably and electrically, avoiding the use of multiple independent wires for traction, and effectively simplifying the structure.

[0013] Specifically, the slide seat further includes a guide end cover, the guide end cover is provided with a guide groove corresponding to the slide groove one by one, and the entrance of the guide groove is gradually narrowed from the outside to the inside. Since the contact head needs to move a certain distance before leaving the seat body and reconnecting to the seat body, it is possible that the contact head will deflect during this process. Therefore, by providing the guide end cover, the position of the contact head can be automatically guided when the contact head re-enters the slide groove, thereby ensuring that the contact head accurately cooperates with the slide groove to conduct electricity, thereby improving the stability of the electrical connection.

[0014] Specifically, the sliding head further includes a sliding sleeve and a first elastic member, the contact portion of the contact head is pivotally connected to one end of the connecting shaft, the contact head is slidably sleeved on the sliding sleeve through the connecting shaft, and the contact head can be elastically matched with the sliding groove through the cooperation between the connecting shaft and the sliding sleeve, thereby improving the stability of the connection. The first elastic member is arranged between the contact head and the sliding sleeve to buffer the contact head.

[0015] Specifically, the slider further includes a support arm, and the support arm is connected to the sliding sleeve.

[0016] Specifically, the sliding contact mechanism further includes a mounting seat and a second elastic member, and the support arms of the two sliders are both pivotally connected to the mounting seat. The second elastic member is arranged between the mounting seat and the support arm. By arranging the second elastic member and the support arm, the slider can maintain the mating contact with the slider, which not only plays a buffering role, but also ensures the stability of the electrical conduction between the slider and the slider.

[0017] Preferably, the multi-story parking garage also includes a frame, which includes vertical support beams, transverse support beams and longitudinal support beams. The vertical support beams are arranged at four corners to form the lifting shaft. The inner side of the vertical support beams is provided with a vertical slide rail for the comb tooth mechanism to slide. The two transverse support beams are respectively arranged on the two vertical support beams on the same side in a one-to-one correspondence. The transverse support beams are provided with transverse slide rails for the comb tooth transverse movement device to slide. The longitudinal support beam is connected between the two transverse support beams and forms a frame with the two transverse support beams. The parking garage is formed between the two adjacent frames.

[0018] Specifically, the comb tooth mechanism includes a pair of lifting beams longitudinally and horizontally arranged in the lifting shaft, and second comb teeth respectively arranged on the inner sides of the lifting beams, and a matching area for avoiding the comb tooth transverse movement device is formed between the two second comb teeth. The two ends of each lifting beam are respectively slidably arranged on the vertical support beam corresponding to the end.

[0019] Specifically, the lift includes a lifting motor, a first rotating shaft, a second rotating shaft, a pair of transmission chains and four lifting chains. The output end of the lifting motor is connected to the first rotating shaft. The first rotating shaft is arranged horizontally and its two ends are connected to the second rotating shaft through the transmission chain. The two ends of the first rotating shaft and the second rotating shaft are respectively connected to the lifting chains. The ends of each lifting beam are connected to the lifting chain one by one. By setting the first rotating shaft, the second rotating shaft, the transmission chain and the lifting chain, only one lifting motor is needed to drive the four corners of the comb mechanism to rise or fall synchronously, which simplifies the structure and ensures the stability of lifting.

[0033] In order to explain the technical content, structural features and achieved effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0034] like Figure 1 and Figure 2 As shown, the three-dimensional parking garage 100 of the present invention includes a lift shaft 1, a parking garage 2, a comb-tooth mechanism 3, an elevator 4 and a comb-tooth transverse movement device 5; the parking garages 2 are arranged on opposite sides of the lift shaft 1, and the parking garages 2 on the same side are stacked up and down; the comb-tooth mechanism 3 is arranged in the lift shaft 1 to slide vertically; the elevator 4 is arranged in the lift shaft 1 and drives the comb-tooth mechanism 3 to move up and down; the comb-tooth transverse movement device 5 is arranged in each of the parking garages 2, and can move horizontally between the corresponding parking garage 2 and the lift shaft 1, so that the vehicle can be transferred between the comb-tooth mechanism 3 and the parking garage 2. Specifically, as follows:

[0035] See also Figure 3 and Figure 4 The comb teeth transverse movement device 5 includes a bracket 51, a roller 52, a first comb tooth 53 and a driving mechanism 54. The rollers 52 are respectively arranged at the two ends of the bracket 51. The first comb teeth 53 are arranged on the bracket 51 for the wheels of the vehicle to bear, and the first comb teeth 53 and the comb teeth of the comb tooth mechanism 3 are staggered; the output end of the driving mechanism 54 is connected to the roller 52 to drive the rollers 52 at the two ends of the bracket 51 to move synchronously. Specifically, the bracket 51 includes two cross beams 511 and two longitudinal beams 512, and the cross beams 511 are arranged at the two ends of the longitudinal beam 512. The two cross beams 511 and the two longitudinal beams 512 form two parallel I-shaped structures, and each cross beam 511 is provided with five rollers 52, and the five rollers 52 are located on the outside of the cross beam 511.

[0036] For example Figure 3 and Figure 4 As shown, the height of the bearing surface of the first comb teeth 53 is lower than the height of the bearing surface of the bracket 51, so that the bracket 51 bears the chassis of the vehicle, and the first comb teeth 53 bear the wheels of the vehicle. In this way, most of the weight of the vehicle can be borne by the bracket 51, and the first comb teeth 53 only bear the weight of the wheels, which greatly reduces the structural strength requirements of the first comb teeth 53. Therefore, the structure of the first comb teeth 53 can be simplified and the amount of steel used in the first comb teeth 53 can be reduced. In addition, the first comb teeth 53 can also prevent the wheels of the vehicle from sagging excessively, thereby saving and reducing the floor height of the single-story parking garage 2 and improving the utilization rate of the space. The first comb teeth 53 include first front comb teeth 531 and first rear comb teeth 532. The first front comb teeth 531 are arranged on both sides of the front section of the bracket 51, and the first rear comb teeth 532 are arranged on both sides of the rear section of the bracket 51. The first front comb teeth 531 and the first rear comb teeth 532 are both formed by rods arranged side by side longitudinally. Taking the position of the first front comb teeth 531 as a reference, the longitudinal length of the first rear comb teeth 532 is longer than that of the first front comb teeth 531 to adapt to vehicles with different wheelbase lengths. The bearing surface of the bracket 51 is provided with an auxiliary pad 51a. The auxiliary pad 51a can buffer the chassis of the vehicle and protect the chassis from being crushed. Of course, the first comb teeth 531 can also be used as the bearing surface. When carrying a vehicle, the surface of the bracket 51 is lower than the chassis of the vehicle and will not carry the chassis. At this time, the weight of the vehicle is applied to the first comb teeth 531 through the wheels.

[0037] Please refer to Figure 3 and Figure 4The driving mechanism 54 includes a motor 541, two gear chain sets 542 and a linkage shaft 543. The motor 541 and the gear chain set 542 are arranged on the crossbeam 511 of the bracket 51. The output end of the motor 541 drives the linkage shaft 543 to rotate, wherein one of the gear chain sets 542 is connected to the roller 52 on the crossbeam 511 on that side, and the other gear chain set 542 is connected to the roller 52 on the other crossbeam 511. The linkage shaft 543 is connected to the two gear chain sets 542 respectively, so that the two gear chain sets 542 synchronously drive the rollers 52 on the two crossbeams 511.

[0038] See also Figures 4 to 7 The comb-tooth transverse movement device 5 also includes a sliding contact mechanism 55, which includes at least two slides 551 and at least two sliders 552 that are spaced apart. The present application has two slides 551 and two sliders 552. The side of the parking garage 2 and the side wall of the elevator shaft 1 corresponding to the horizontal position are respectively provided with the slides 551, and the slides 551 extend along the transverse movement direction of the comb-tooth transverse movement device 5; the spacing between the two sliders 552 should be greater than the spacing between the two sliders 551; at least one slider 552 is slidably matched with one of the slides 551 and is in conductive contact to ensure that the comb-tooth transverse movement device 5 can be continuously powered when it moves.

[0039] Please see again Figure 6 and Figure 7 Specifically, the slide 551 includes a seat body 551a and a guide end cover 551b. The seat body 551a is provided with a plurality of slide grooves 551c. The slide grooves 551c are provided with conductive busbars 551d. The slider 552 is provided with a plurality of conductive contact heads 552a. The ends of the contact heads 552a are slidably matched with the slide grooves 551c and electrically contacted with the busbars 551d. Each contact head 552a is connected with a wire. By providing the slide grooves 551c and the contact heads 552a, the slider 552 and the slide seat 551 can be both slidably connected and electrically connected, avoiding the use of multiple independent wires for traction, and effectively simplifying the structure. The guide end cover 551b is provided with guide grooves 551e corresponding to the slide grooves 551c. The entrance of the guide grooves 551e is gradually narrowed from the outside to the inside. Since the contact head 552a needs to move a certain distance before it detaches from the seat body 551a and reconnects to the seat body 551a, deviation may occur during this process. Therefore, by providing the guide end cover 551b, the position of the contact head 552a can be automatically guided when the contact head 552a re-enters the slide groove 551c, thereby ensuring that the contact head 552a accurately cooperates with the slide groove 551c for conduction, thereby improving the stability of the electrical connection.

[0040] For example Figure 7 As shown, the sliding head 552 further includes a sliding sleeve 552b, a first elastic member 552c and a support arm 552d, and the contact head 552a is slidably sleeved on the sliding sleeve 552b. The first elastic member 552c is arranged between the contact head 552a and the sliding sleeve 552b to buffer the contact head 552a; the first elastic member 552c is a compression spring. The contact head 552a is provided with a connecting shaft 552e, and the contact portion of the contact head 552a is pivotally connected to one end of the connecting shaft 552e, and the connecting shaft 552e is slidably sleeved in the sliding sleeve 552b. Through the cooperation of the connecting shaft 552e and the sliding sleeve 552b, the contact head 552a can be elastically cooperated with the sliding groove 551c, thereby improving the stability of the connection. The other end of the connecting shaft 552e is provided with a limiting portion 552f, and the limiting portion 552f abuts against the end of the sliding sleeve 552b. Specifically, the limiting portion 552f is a V-shaped convex portion, and the end of the sliding sleeve 552b is provided with a V-shaped limiting groove 552g that cooperates with the convex portion. The V-shaped cooperation between the convex portion and the limiting groove 552g can prevent the connecting shaft 552e from excessively extending or detaching from the sliding sleeve 552b to ensure the stability of the structure, and can also automatically guide the contact head 552a to adjust the angle by using the V-shaped inclined surface during resetting to ensure that the contact head 552a does not deflect excessively and avoid the situation where it cannot slide into the sliding groove 551c. The support arm 552d is connected to the sliding sleeve 552b.

[0041] For example Figure 7 As shown, the sliding contact mechanism 55 further includes a mounting seat 553 and a second elastic member 554, and the two support arms 552d are both pivotally connected to the mounting seat 553. The second elastic member 554 is arranged between the mounting seat 553 and the support arm 552d, and the second elastic member 554 is a compression spring. By arranging the second elastic member 554 and the support arm 552d, the slider 552 can maintain the contact with the slider 551, which not only plays a buffering role, but also ensures the stability of the electrical conduction between the slider 552 and the slider 551.

[0042] See also Figure 8The three-dimensional parking garage 100 further comprises a frame 6, which comprises a vertical support beam 61, a transverse support beam 62 and a longitudinal support beam 63. The vertical support beam 61 is arranged at four corners to form the lifting shaft 1. The inner side of the vertical support beam 61 is provided with a vertical slide rail 611 for the comb mechanism 3 to slide. In each parking garage 2, the two transverse support beams 62 are respectively arranged on the two vertical support beams 61 on the same side in a one-to-one correspondence. The transverse support beam 62 is provided with a transverse slide rail 621 for the comb transverse movement device 5 to carry and slide. The slide seat 551 of the sliding contact mechanism 55 is arranged on the transverse support beam 62. The longitudinal support beam 63 is connected between the two transverse support beams 62 and is located at the end of the transverse support beam 62, so that it forms a square frame with the two transverse support beams 62, and the parking garage 2 is formed between the upper and lower adjacent frames.

[0043] like Fig. 9 As shown, the comb mechanism 3 includes a pair of lifting beams 31 longitudinally and horizontally arranged in the lifting shaft 1, and second comb teeth 32 respectively arranged on the inner side of the lifting beams 31, and a matching area 33 for avoiding the comb transverse movement device 5 is formed between the two second comb teeth 32. The second comb teeth 32 include second front comb teeth 321 and second rear comb teeth 322. When the first comb teeth 53 cooperate with the second comb teeth 32, the second front comb teeth 321 and the first front comb teeth 531 are staggered and close to each other in the vertical direction and extend into each other's comb tooth gap. The two ends of each lifting beam 31 are respectively slidably arranged on the vertical support beam 61 corresponding to the end.

[0044] Please refer to Figure 2 The lift 4 includes a lift motor 41, a first rotating shaft 42, a second rotating shaft 43, a pair of transmission chains 44 and four lift chains 45. The output end of the lift motor 41 is connected to the first rotating shaft 42. The first rotating shaft 42 is arranged horizontally and its two ends are connected to the second rotating shaft 43 through the transmission chain 44. The two ends of the first rotating shaft 42 and the second rotating shaft 43 are respectively connected to the lift chains 45. The ends of each lift beam 31 are connected to the lift chains 45 one by one. By providing the first rotating shaft 42, the second rotating shaft 43, the transmission chain 44 and the lift chain 45, only one lift motor 41 is needed to drive the four corners of the comb mechanism 3 to rise or fall synchronously, which simplifies the structure and ensures the stability of lifting.

[0045] Combining the above and Figure 1 , Figures 11 to 13 The working principle of the stereo garage 100 of the present invention is described in detail below:

[0046] When parking is required, the elevator 4 drives the comb mechanism 3 to descend to the bottom layer, and then sends the trolley into the elevator shaft 1, so that the trolley is carried on the comb mechanism 3 and the front wheel of the trolley is carried on the second front comb teeth 321, and the rear wheel is carried on the second rear comb teeth 322. After that, the elevator 4 drives the comb mechanism 3 to rise to drive the trolley to the parking garage 2 where it needs to be parked. At this time, the horizontal height of the comb mechanism 3 should be slightly higher than the horizontal height of the parking garage 2, so that the comb transverse movement device 5 can enter the elevator shaft 1 and be located below the comb mechanism 3. At this time, the motor 541 starts, and drives the rollers 52 on the two beams 511 to connect through the gear chain and the linkage shaft 543, thereby driving the comb transverse movement device 5 to move horizontally as a whole, that is, to move horizontally from the parking garage 2 to the elevator shaft 1. At the same time, the slider 552 slides on the slide seat 551 and remains powered. When the comb-tooth transverse moving device 5 passes over the vertical support beam 61, the slider 552 at the front leaves the slide seat 551 in the parking garage 2 first, and the slider 552 at the rear still maintains conductive cooperation with the slide seat 551. When the slider 552 at the front just conducts with the slide seat 551 in the elevator shaft 1, the slider 552 at the rear has not yet separated from the slide seat 551 in the parking garage 2 but is about to separate from it. When the comb-tooth transverse moving device 5 completely enters the elevator shaft 1, the slider 552 at the front and the slider 552 at the rear are both conductively matched with the slide seat 551 in the elevator shaft 1, so the whole process can remain powered. At this time, the lift 4 drives the comb mechanism 3 to move downward so that its horizontal height is lower than the horizontal height of the comb transverse moving device 5; in this process, the comb transverse moving device 5 passes through the matching area 33 of the comb mechanism 3, and the first comb teeth 53 and the second comb teeth 32 pass through each other's comb teeth gap without interference, so that the trolley is placed on the comb transverse moving device 5. At this time, the chassis of the trolley is supported on the longitudinal beam 512, the front wheels of the trolley are supported on the first front comb teeth 531, and the rear wheels of the trolley are supported on the first rear comb teeth 532. Afterwards, the comb transverse moving device 5 moves horizontally from the lift shaft 1 to the original parking garage 2, and the trolley can be parked.

[0047] When it is necessary to take a car from the parking garage 2, it is only necessary to control the comb-tooth transverse moving device 5 carrying the trolley to move from the parking garage 2 to the elevator shaft 1 at the same level. At this time, the elevator 4 drives the comb-tooth mechanism 3 to rise and pass through the comb-tooth transverse moving device 5 to be located above the comb-tooth transverse moving device 5. In this process, the comb-tooth mechanism 3 can transfer the trolley to itself and drive the trolley to rise a certain distance and leave the comb-tooth transverse moving device 5. After that, the comb-tooth transverse moving device 5 moves from the elevator shaft 1 back to the original parking garage 2. Finally, the elevator 4 drives the comb-tooth mechanism 3 carrying the trolley to descend and return to the bottom layer. At this time, the trolley can be sent out of the elevator shaft 1 and taken out.

[0048] Compared with the prior art, the present invention respectively sets a slide 551 on the side of the parking garage 2 and the side wall of the elevator shaft 1 corresponding to the horizontal position, and then sets two sliders 552 which are isolated from each other by a certain distance; when the comb-tooth transverse movement device 5 moves from the parking garage 2 to the elevator shaft 1, the front slider 552 leaves the slide 551 located on the parking garage 2, but the rear slider 552 is still located on the slide 551 of the parking garage 2, and before the rear slider 552 leaves the parking garage, the front slider 552 is electrically contacted with the slide 551 located on the elevator shaft 1, so that at least one of the sliders 552 can slide and cooperate with one of the slides 551 and be in conductive contact, thereby ensuring that the comb-tooth transverse movement device 5 can continuously obtain power when it moves, avoiding the situation where the motor 541 is powered off. Therefore, the comb-tooth transverse moving device 5 can be made to drive all the rollers 52 to move synchronously with a single motor 541, avoiding the traditional method of using four motors 541 to drive each roller 52 to move separately, reducing the drive by three quarters, greatly simplifying the structure of the comb-tooth transverse moving device 5, thereby reducing the overall strength requirements of the garage, making the control simpler and more convenient, reducing the failure rate of the equipment, improving stability, and effectively reducing production costs, which is conducive to wide application.

[0049] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
