Description

Technical Field

[0002] Mechanical automated parking systems are on the rise in China due to their space-saving design, high speed, large parking capacity, and smooth traffic flow.

[0003] In existing mechanical automated parking systems, when customers are parking their cars in the parking compartment, the parking section's lifting platform functions as a platform, and the central high-speed lifting door functions as a safety isolation door. During the transfer of vehicles between the parking compartment and the elevator, both the parking section's lifting platform and the high-speed lifting door must be raised to ensure unobstructed passage. However, current technology operates the high-speed lifting door and the parking section's lifting platform separately; when opening, the high-speed lifting door rises first, followed by the parking section's lifting platform; when closing, the parking section's lifting platform lowers first, followed by the high-speed lifting door. This is inefficient and wastes time when storing and retrieving vehicles. Summary of the Invention

[0038] The following is in conjunction with the appendix Figure 1-12 The present invention will be described in further detail below.

[0039] Example 1

[0040] like Figure 1-12 As shown, a three-dimensional parking lot platform integrated door device includes a lifting door mounting frame 2 and a platform mounting frame 3 installed on the entrance / exit garage 1; a lifting door mechanism 4 is movably connected inside the lifting door mounting frame 2, and a lifting platform mechanism 5 is slidably connected inside the platform mounting frame 3; a drive mechanism 6 drives the lifting platform mechanism 5 and the lifting door mechanism 4 to control the lifting door mechanism 4 to roll up and open when the lifting platform mechanism 5 slides upward or to unfold and close when the lifting platform mechanism 5 slides downward.

[0041] The present invention discloses an integrated door device for a three-dimensional parking platform. The device can synchronously control the lifting door mechanism 4 and the lifting platform mechanism 5 through its internal drive mechanism 6. When the drive mechanism 6 is activated, and the lifting platform mechanism 5 slides upward on the platform mounting frame 3, the lifting door mechanism 4 installed in the lifting door mounting frame 2 can be synchronously controlled to open. Conversely, when the drive mechanism 6 drives the lifting platform mechanism 5 to slide downward on the platform mounting frame 3, the lifting door mechanism 4 installed in the lifting door mounting frame 2 can be synchronously controlled to close. Synchronous control of the lifting door mechanism and the lifting platform mechanism is achieved using only one motor, enabling smooth linkage between the lifting door mechanism and the lifting platform mechanism within a limited space. This effectively improves parking efficiency and saves parking and retrieval time.

[0042] Example 2

[0043] like Figure 1-12As shown, the lifting platform mechanism 5 includes a platform assembly 51, a sliding frame 52, sliding rollers 53, and limiters 54; the platform assembly 51 is connected to the drive mechanism 6; two sliding frames 52 are fixed on the platform assembly 51, and the two sliding frames 52 slide relative to each other on two longitudinal guide rails of the platform mounting frame 3; multiple sliding rollers 53 are rotatably connected to each sliding frame 52, and the sliding rollers 53 roll in the longitudinal slide rails of the longitudinal guide rails; multiple limiters 54 are detachably connected to each sliding frame 52, and the limiters 54 slide on the outer surface of the longitudinal guide rails.

[0044] The present invention discloses an integrated door device for a three-dimensional parking platform. After the internal drive mechanism 6 is activated, it can drive the platform assembly 51 to move vertically. The platform assembly 51 drives two sliding frames 52 to slide vertically on the two longitudinal guide rails of the platform mounting frame 3, making the lifting and lowering movement of the platform assembly 51 relatively stable. Each sliding frame 52 is rotatably connected to multiple sliding rollers 53. The multiple sliding rollers 53 roll and cooperate within the longitudinal slide rails of the longitudinal guide rails, reducing the frictional resistance when the sliding frame 52 slides vertically and improving the sliding motion effect. Each sliding frame 52 is detachably connected to multiple limiters 54. The limiters 54 slide on the outer surface of the longitudinal guide rails, limiting the relative positions of the sliding frame 52, sliding rollers 53, and longitudinal guide rails, preventing the sliding frame 52 and sliding rollers 53 from detaching from the longitudinal guide rails, thus improving the stability of the invention during use.

[0045] Example 3

[0046] like Figure 1-12 As shown, the lifting door mechanism 4 includes a linkage sprocket 41, a roll-up shaft 42, and a roller shutter door 43; the two ends of the roll-up shaft 42 rotate relative to each other on both sides of the top of the lifting door mounting frame 2; the linkage sprocket 41 is fixed on the roll-up shaft 42, and the linkage sprocket 41 is connected to the drive mechanism 6 for transmission; the roll-up shaft 42 is fixedly connected to one end of the roller shutter door 43, and the other end of the roller shutter door 43 is slidably fitted in the longitudinal groove of the lifting door mounting frame 2.

[0047] After the drive mechanism 6 is started, it can drive the linkage sprocket 41 to rotate. When the lifting platform mechanism 5 slides upward on the platform mounting frame 3, the linkage sprocket 41 rotates and drives the roll-up shaft 42 to rotate, thereby rolling up the roller shutter door 43 through the roll-up shaft 42 to realize the opening of the lifting door mechanism 4. When the lifting platform mechanism 5 slides downward on the platform mounting frame 3, the roll-up shaft 42 unrolls the roller shutter door 43 to realize the closing of the lifting door mechanism 4.

[0048] Example 4

[0049] like Figure 1-12As shown, the drive mechanism 6 includes a power unit 61, a counterweight slider 62, a chain connecting rod 63, and a drive chain 64. The power unit 61 is mounted on the platform mounting frame 3 to drive the counterweight slider 62 to slide vertically up and down on the platform mounting frame 3. The chain connecting rod 63 is fixed on the counterweight slider 62. One end of the chain connecting rod 63 is fixed to the drive chain 64. The middle part of the drive chain 64 is connected to the upper part of the linkage sprocket 41. The other end of the drive chain 64 is fixed to the platform assembly 51.

[0050] After the power unit 61 is powered on, it can drive the counterweight slider 62 to slide vertically up and down on the platform mounting frame 3. The weight of the counterweight slider 62 is based on a preset weight and is not less than the sum of the weight of the personnel or goods it can carry and the weight of the lifting platform mechanism 5. When the counterweight slider 62 moves downward on the platform mounting frame 3, it drives one end of the drive chain 64 through the chain connecting rod 63. The drive chain 64 is engaged with the linkage sprocket 41, thereby driving the platform assembly 51 upward through the other end of the drive chain 64. At the same time, the drive chain 64 and the linkage sprocket 41 work together to drive the linkage sprocket 41 to rotate, thereby achieving the winding of the roller shutter door 43. Conversely, when the counterweight slider 62 moves upward on the platform mounting frame 3, the platform assembly 51 moves downward under its own gravity, thereby driving one end of the drive chain 64 downward. The drive chain 64 drives the unwinding shaft 42 to unwind the roller shutter door 43, thereby achieving the closing of the lifting door mechanism 4.

[0051] Example 5

[0052] like Figure 1-12 As shown, the power unit 61 includes a power unit mounted on the platform mounting frame 3 to drive the counterweight slider 62 to slide vertically up and down on the platform mounting frame 3; the power unit 61 also includes a double-row sprocket, the double-row sprocket is fixed on the sprocket shaft, the sprocket shaft rotates on the platform mounting frame 3, a first chain and a second chain are connected above the double-row sprocket, one end of the first chain and one end of the second chain are both fixed on the counterweight slider 62, the middle part of the first chain is connected to the first single-row sprocket, and the other end of the first chain is fixed to a sliding frame 52; the middle part of the second chain is connected to the second single-row sprocket, and the other end of the second chain is fixed to another sliding frame 52; the first single-row sprocket and the second single-row sprocket rotate on both sides above the platform mounting frame 3.

[0053] The power unit is used to drive the counterweight slider 62 to slide vertically up and down on the platform mounting frame 3, thereby controlling the operation of the invention. The power unit 61 also includes a double-row sprocket, a sprocket shaft, a first chain, a second chain, a first single-row sprocket, and a second single-row sprocket. When the counterweight slider 62 moves up and down, it drives one end of the first chain and one end of the second chain to move. One end of the first chain and one end of the second chain are supported by the first single-row sprocket and the second single-row sprocket, respectively. The other ends of the first single-row sprocket and the second single-row sprocket are connected to the two sliding frames 52, thereby driving the sliding frames 52 to move up and down. This ensures that the internal drive mechanism 6 of the invention is connected to the internal platform component 51 and the two sliding frames 52 of the lifting platform mechanism 5, improving the stability of its control over the movement of the lifting platform mechanism 5, preventing a dangerous situation caused by the breakage of a chain, and improving the stability and safety during operation.

[0054] The power unit includes a geared motor, with a drive sprocket fixed to its output shaft. The drive sprocket drives a driven sprocket via a chain, and the driven sprocket is fixed to the sprocket shaft. When the geared motor starts, it drives the drive sprocket to rotate. The rotation of the drive sprocket drives the driven sprocket to rotate, which in turn drives the sprocket shaft to rotate. The rotation of the sprocket shaft drives the double-row sprockets to rotate, thereby controlling the movement of the first and second chains through the double-row sprockets, and controlling the movement of the counterweight slider 62 through the first and second chains.

[0055] Example 6

[0056] like Figure 1-12 As shown, the integrated door device for a three-dimensional parking platform further includes a lower platform mechanism 7; the lower platform mechanism 7 includes a platform body 71, which is connected to the bottom of the platform assembly 51 through two hanger units 72; the output end of the drive unit 73 fixed on the platform body 71 is fixed with an active bevel gear 74, which meshes vertically with a driven bevel gear 76 fixed on a rotating tube 75; the rotating tube 75 rotates in the longitudinal hole of the platform body 71; the rotating tube 75 is threaded with a vertical screw 77; a protective baffle 78 is fixed at the top of the vertical screw 77; the protective baffle 78 is located on the side of the platform assembly 51 away from the sliding frame 52; multiple vertical sliding shafts 79 are fixed at the lower end of the protective baffle 78; the middle of the vertical sliding shafts 79 slides in the vertical slide rail of the platform body 71.

[0057] The lower platform mechanism 7 is an auxiliary device of the present invention, and its installation can be selected according to actual conditions. Under normal conditions, the top surface of the protective baffle 78 is kept coplanar with the top surface of the lifting platform mechanism 5. When other functions are required, it can be deformed. The lower platform mechanism 7 can be deformed to form a protective mechanism. When the lifting platform mechanism 5 is raised inside the present invention, it can be controlled to deform into a protective mechanism by the drive unit 73. After the drive unit 73 is started, it can drive the active bevel gear 74 to rotate, thereby driving the driven bevel gear 76 to rotate through the meshing of the active bevel gear 74. When the driven bevel gear 76 rotates, it can drive the rotating tube 75 to rotate. When the rotating tube 75 rotates, it can change its contact position with the vertical screw 77, thereby controlling the vertical screw 77 to drive the protective baffle 78 to move up and down. The protective baffle 78 drives the middle part of multiple vertical sliding shafts 79 to slide in the vertical slide rail of the platform body 71, thereby forming a protective mechanism through the protective baffle 78 and multiple vertical sliding shafts 79.

[0058] The hanger unit 72 includes a rack 721, with both ends of the rack 721 fixed to the bottom surface of the platform assembly 51 via two hanger seats 722. The middle part of the rack 721 is slidably engaged in the transverse slide rail of the slide rail frame 723, which is fixed to the platform body 71. A bearing tube 724 is rotatably connected inside the slide rail frame 723, and a gear 725 fixed on the bearing tube 724 meshes with the teeth on the bottom surface of the rack 721. The lower platform mechanism 7 also includes an unlocking transmission component 8 that is connected to the drive unit 73. The unlocking transmission component 8 can relatively lock the platform body 71 and the platform assembly 51 or control the rotation of the bearing tube 724 in the two hanger units 72.

[0059] The structure of the hanger unit 72 allows the lower platform mechanism 7 inside the invention to also be used as an extended platform, expanding the support area. When it is necessary to use it as an extended platform, the unlocking transmission component 8 is controlled to release the relative locking of the platform body 71 and the platform component 51. At this time, the unlocking transmission component 8 is connected to the bearing tubes 724 in the two hanger units 72. When the drive unit 73 controls the protective baffle 78 and multiple vertical sliding shafts 79 to form a protective mechanism, the bearing tubes 724 and gears 725 of the two hanger units 72 are rotated synchronously. When the two gears 725 rotate, they mesh with the two racks 721, causing the two sliding brackets 723 to slide outward on the two racks 721, thereby extending the platform body 71 to the outside of the platform component 51. At this time, the drive unit 73 realizes the synchronous control of the two functions of "protective mechanism" and "extended platform", which is convenient to operate and highly practical.

[0060] The drive unit 73 includes a first motor 731 fixed on the platform body 71. The output shaft of the first motor 731 is connected to one end of a worm gear 732. The middle of the worm gear 732 meshes with a worm wheel 733, which is fixed on a central rotating tube 734. The central rotating tube 734 rotates on the platform body 71 and is connected to the unlocking transmission assembly 8. The other end of the worm gear 732 is fixed with a drive bevel gear 74. After the first motor 731 is started, it can drive the worm gear 732 to rotate. When the worm gear 732 rotates, it can drive the drive bevel gear 74 to rotate, thereby realizing the control of the "protective mechanism" function. When the worm gear 732 rotates, it can mesh with the worm wheel 733 to rotate, thereby driving the central rotating tube 734 to rotate. When the central rotating tube 734 rotates, it controls the rotation of the bearing tubes 724 and gears 725 of the two hanger units 72 through the unlocking transmission assembly 8.

[0061] The unlocking transmission assembly 8 includes a second motor 81 fixed on the tabletop body 71. The output end of the second motor 81 is driven by a bidirectional screw 82 rotating on the tabletop body 71. The two ends of the bidirectional screw 82 are threadedly driven by two displacement slides 83 sliding on the tabletop body 71. The two displacement slides 83 are rotatably connected to one end of two unlocking connecting rods 84, and the other end of the two unlocking connecting rods 84 is rotatably connected to the lower end of two locking rods 85. The middle of the two locking rods 85 slides on two guide frames 86. The support frame 86 is fixed on the platform body 71, and the upper ends of the two locking rods 85 can be inserted into the locking holes on the bottom surface of the platform assembly 51; a linkage shaft 87 is rotatably connected to each of the two displacement slides 83, the inner ends of the two linkage shafts 87 slide in the central rotating tube 734, the first protrusion in the central rotating tube 734 slides in the linkage groove of the linkage shaft 87, the outer ends of the two linkage shafts 87 slide in the two bearing tubes 724, and the second protrusion in the bearing tube 724 slides in the linkage groove of the linkage shaft 87.

[0062] The two locking rods 85 inside the unlocking transmission assembly 8 are inserted into the two locking holes. Thus, when the tabletop body 71 and platform assembly 51 are relatively locked, the two linkage shafts 87 of the unlocking transmission assembly 8 are separated from the two bearing tubes 724. When the two locking rods 85 disengage from the two locking holes, the two linkage shafts 87 are inserted into the two bearing tubes 724. This ensures the relative fixation of the tabletop body 71 and platform assembly 51 when the tabletop body 71 does not need to extend outwards. During control, after the second motor 81 starts, it can drive the bidirectional screw 82 to rotate. One end of the bidirectional screw 82 has a left-hand thread, and the other end has a right-hand thread. When the bidirectional screw 82 rotates, it can drive the two displacement slides. When the two displacement slide blocks 83 slide towards each other or away from each other, they drive one end of the two unlocking linkages 84 to move inward, and the other end of the two unlocking linkages 84 pushes the two locking rods 85 to slide upward on the two guide frames 86, thereby inserting them into the locking holes on the bottom surface of the platform assembly 51. When the two displacement slide blocks 83 slide away from each other, they drive the two locking rods 85 to disengage from the locking holes and drive the two linkage shafts 87 to move outward so as to insert them into the two bearing tubes 724. When the central rotating tube 734 rotates, it can drive the linkage shaft 87 to rotate through the cooperation of the first protrusion and the linkage groove. When the linkage shaft 87 rotates, it can drive the bearing tube 724 to rotate through the cooperation of the linkage groove and the second protrusion.

[0063] The principle of this invention is as follows:

[0064] The present invention discloses an integrated door device for a three-dimensional parking platform. The device can synchronously control the lifting door mechanism 4 and the lifting platform mechanism 5 through its internal drive mechanism 6. When the drive mechanism 6 is activated, and the lifting platform mechanism 5 slides upward on the platform mounting frame 3, the lifting door mechanism 4 installed in the lifting door mounting frame 2 can be synchronously controlled to open. Conversely, when the drive mechanism 6 drives the lifting platform mechanism 5 to slide downward on the platform mounting frame 3, the lifting door mechanism 4 installed in the lifting door mounting frame 2 can be synchronously controlled to close. Synchronous control of the lifting door mechanism and the lifting platform mechanism is achieved using only one motor, enabling smooth linkage between the lifting door mechanism and the lifting platform mechanism within a limited space. This effectively improves parking efficiency and saves parking and retrieval time.

[0065] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.

[0066] It should also be noted that, in this specification, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
