Description

Technical Field

[0001] This utility model belongs to the field of automated parking system technology, and in particular relates to a buffer parking space. Background Technology

[0002] In modern urban parking solutions, multi-level parking garages are widely used as a highly efficient space-utilizing parking facility. To facilitate temporary parking and vehicle transfer, multi-level parking garages typically include buffer parking spaces and vehicle transport devices for moving vehicles from these spaces. To further facilitate the transport of vehicles with different chassis heights from the buffer parking spaces, related technologies incorporate tire supports on the support surface of the buffer parking spaces. These tire supports are higher than the support surface of the buffer parking spaces to increase the height of the vehicle chassis, thus preventing collisions between the vehicle transport device and the chassis when moving the vehicle from below. However, this design poses a risk that the wheels may fall off the tire supports as the vehicle is parked in the buffer parking space, potentially leading to instability, vehicle damage, and increased parking difficulty for users.

[0003] Therefore, how to design buffer parking spaces that are both convenient for users to park their vehicles reliably and enable vehicle transport devices to reliably transport vehicles from the bottom is a problem that urgently needs to be solved in automated parking systems. Utility Model Content

[0004] To address the shortcomings of related technologies, this utility model provides a buffer parking space. By setting a micro-lifting mechanism in the groove, the micro-lifting mechanism can block these grooves or channels, preventing the wheels from getting stuck in the grooves or channels when passing through them.

[0005] This utility model provides a buffer parking space, including:

[0006] The buffer parking space is provided with a support surface for supporting the wheels. The middle of the buffer parking space is also provided with a through groove for the vehicle transport device to pass through. The opening of the through groove is located on the support surface. A micro-lifting mechanism is provided in the through groove. The micro-lifting mechanism has a lifting surface that can be raised and lowered so that the lifting surface is flush with the support surface.

[0007] Micro-lift institutions include:

[0008] The movable frame is defined by a guide surface, which is an upwardly inclined slope;

[0009] The driving component, which is connected to the moving frame, is used to drive the moving frame to reciprocate linear motion in the horizontal plane;

[0010] The lifting frame is vertically opposite to the moving frame; the lifting surface is located on the side of the lifting frame away from the moving frame; the side of the lifting frame facing the moving frame is connected to rollers and mating parts, and the rollers are in contact with the guide surface.

[0011] The support frame is equipped with limiting components, which are correspondingly set and cooperate with the mating components to restrict the lifting frame to move only in the vertical direction.

[0012] When the driving component drives the moving frame to move in a straight line in the horizontal plane, the rollers move upward along the guide surface to lift the lifting frame so that the lifting surface is flush with the support surface.

[0013] When the driving component drives the moving frame to move in the opposite direction along a straight line in the horizontal plane, the rollers move downward along the guide surface, lowering the lifting frame so that the height of the lifting surface is lower than the support surface.

[0014] This technical solution uses a micro-lifting mechanism within the slots to seal them, preventing wheels from getting stuck. The micro-lifting mechanism is designed to include a moving frame, a lifting frame, and a support frame. The moving frame has an upwardly inclined guide surface, allowing the lifting frame and moving frame to engage via the inclined surface. The moving frame's horizontal linear movement drives the lifting frame's vertical relative movement. Rollers are installed on the lifting frame, rolling along the guide surface to move the lifting frame vertically. Limiting components are installed on the support frame, and mating components are installed on the lifting frame. The cooperation between the limiting and mating components constrains the lifting frame horizontally, restricting its movement to vertical only, thus ensuring the reliability of the lifting frame's movement and consequently the reliability of the micro-lifting mechanism.

[0015] In some embodiments, the movable frame is provided with an insert, and the lifting frame is provided with a connector. The connector has an opening for the insert to be inserted, and the opening is arranged along the movement direction of the movable frame. When the movable frame moves in the opposite direction and the roller disengages from the guide surface, the movable frame drives the insert to apply a downward force to the connector, thereby lowering the lifting frame.

[0016] This technical solution involves setting an insert in the moving frame and a connector in the lifting frame. The insert is inserted into the connector. During the descent of the lifting frame, when the movement of the lifting frame is not synchronized with the movement of the moving frame, the insert can apply a downward force to the connector, thereby causing the lifting frame to fall, thus ensuring the reliability of the micro-lifting mechanism.

[0017] In some embodiments, the insert is disposed along the movement direction of the movable frame, one end of the insert is disposed on the movable frame, and the other end of the insert is disposed toward the connector; the end of the insert toward the connector is a pointed tip, and the insert is defined with a pressing surface, which is an upwardly inclined slope.

[0018] This technical solution designs the surface on which the insert applies tension to the connector as an inclined plane, so that when the lifting frame and the moving frame move synchronously, there is a stable fit gap between the insert and the connector, and the insert does not apply force to the connector. When the lifting frame and the moving frame move asynchronously, the fit gap between the insert and the connector gradually decreases to 0, so that the insert applies downward pressure to the connector, thereby ensuring the descent of the lifting frame.

[0019] In some embodiments, the movable frame is further defined with a support surface extending along the direction of movement of the movable frame. The support surface is located at the upper and lower ends of the guide surface and is used to support the rollers. When the lifting frame moves to the extreme position of the lifting, the rollers contact the support surface located at the upper end of the guide surface. When the lifting frame moves to the extreme position of the falling, the rollers contact the support surface located at the lower end of the guide surface.

[0020] This technical solution provides support surfaces at the upper and lower ends of the guide surface. When the lifting frame moves to the extreme position of the top, the rollers contact the support surface at the upper end of the guide surface; when the lifting frame moves to the extreme position of the bottom, the rollers contact the support surface at the lower end of the guide surface. This ensures that the rollers stop on the horizontal surface when the lifting frame stops moving, thereby guaranteeing the reliability of the lifting frame's movement and the reliability and safety of the micro-lifting mechanism.

[0021] In some embodiments, the mating parts and the limiting parts can move relative to each other in the vertical direction to guide the lifting frame to rise and fall; the support frame is provided with a guide rail, which is arranged along the movement direction of the moving frame; the moving frame is provided with a slider, which slides along the guide rail to guide the movement of the moving frame.

[0022] In some embodiments, the limiting member is a limiting rod arranged in a vertical direction, and the mating member is two pulleys arranged side by side, with the rotation direction of the pulleys perpendicular to the movement direction of the moving frame in the horizontal plane; the limiting rod is inserted between the two pulleys.

[0023] In some embodiments, the movable frame is located inside the support frame, and the lifting frame is located inside the support frame when it is lowered.

[0024] In some embodiments, two movable frames are provided, which are located at opposite ends of the lifting frame. The two movable frames are driven by the same drive unit and move in opposite directions.

[0025] In some embodiments, the drive component is connected to a screw, the movable frame is equipped with a first connecting block, the support frame is connected to a second connecting block, the second connecting block and the first connecting block are correspondingly arranged along the length direction of the screw, the screw is connected to the first connecting block by a thread, and the screw and the second connecting block are rotatably connected.

[0026] In addition, this utility model also provides a three-dimensional parking garage, including the above-mentioned buffer parking space and a vehicle conveying device. The vehicle conveying device can enter and exit the through channel along the extension direction of the through channel to move vehicles from the bottom of the buffer parking space.

[0027] This technical solution involves setting a vehicle transport device to move in and out of the through channel along its extension direction, so that the vehicle transport device can move vehicles from the bottom of the vehicle to the buffer parking space.

[0028] Based on the above technical solution, in this embodiment of the utility model, the buffer parking space uses a micro-lifting mechanism installed in the through-slot to block the through-slot through which the vehicle conveying device passes, preventing wheels from getting stuck in the through-slot when passing through the slot. The micro-lifting mechanism is designed to include a moving frame, a lifting frame, and a support frame. An upwardly inclined guide surface is provided on the moving frame, allowing the lifting frame and the moving frame to engage via an inclined surface. The moving frame moves horizontally in a straight line, driving the lifting frame to move vertically relative to the moving frame, thus making the lifting surface flush with the support surface, preventing wheels from getting stuck in the through-slot when passing through the slot. The lifting frame is equipped with rollers that roll along a guide surface, allowing the lifting frame to move vertically. Limiting components are installed on the support frame, and mating components are installed on the lifting frame. The cooperation between the limiting and mating components constrains the lifting frame horizontally, restricting its movement to vertical only. This ensures the reliability of the lifting frame's movement and, consequently, the reliability of the micro-lifting mechanism. This, in turn, not only ensures the reliable transport of vehicles from the bottom by the vehicle transport device but also improves the convenience and reliability of parking vehicles in buffer spaces.

[0050] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0052] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0053] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0054] As attached Figures 1-3As shown in an illustrative embodiment of the buffer parking space of this utility model, the buffer parking space is provided with a support surface 701 for supporting wheels. A through groove for a vehicle transport device to pass through is also provided in the middle of the buffer parking space. The opening of the through groove is located on the support surface 701. A micro-lifting mechanism is provided within the through groove. The micro-lifting mechanism has a lifting surface 101, which can be raised and lowered to make the lifting surface 101 flush with the support surface 701. The micro-lifting mechanism includes a movable frame 400, a driving member 300, a lifting frame 100, and a support frame 200. The movable frame 400 is used to drive the lifting frame 100 to rise and fall vertically. The movable frame 400 is defined by a guide surface 450, which is an upwardly inclined surface. The driving member 300 is used to drive the movable frame 400 to reciprocate linearly in a horizontal plane. The driving member 300 is connected to the movable frame 400. The lifting frame 100 is driven by the movable frame 400. The lifting frame 100 and the movable frame 400 are vertically oriented and positioned opposite each other. A lifting surface 101 is located on the side of the lifting frame 100 facing away from the movable frame 400. A roller 120 is connected to the side of the lifting frame 100 facing the movable frame 400, and the roller 120 contacts the guide surface 450. When the movable frame 400 moves horizontally, the lifting frame 100 and the movable frame 400 move relative to each other, causing the roller 120 to roll along the guide surface 450, thus achieving the lifting and lowering of the lifting frame 100. A support frame 200 is used to apply a horizontal constraint to the lifting frame 100, preventing it from moving horizontally. The support frame 200 is equipped with a limiting member 210, and a mating member is provided on the side of the lifting frame 100 facing the movable frame 400. The limiting member 210 and the mating member are correspondingly arranged and cooperate with each other to restrict the lifting frame 100 to move only in the vertical direction.

[0055] When the driving component 300 drives the moving frame 400 to move in a straight line in the horizontal plane, the roller 120 moves upward along the guide surface 450 to lift the lifting frame 100 so that the lifting surface 101 is flush with the support surface 701; when the driving component 300 drives the moving frame 400 to move in a straight line in the horizontal plane in the reverse direction, the roller 120 moves downward along the guide surface 450 to lower the lifting frame 100 so that the height of the lifting surface 101 is lower than the support surface 701.

[0056] The aforementioned buffer parking space utilizes a micro-lifting mechanism within the through-slot to block the passageway for the vehicle transport device, preventing wheels from getting stuck. The micro-lifting mechanism is designed to include a movable frame 400, a lifting frame 100, and a support frame 200. The movable frame 400 has an upwardly inclined guide surface 450, allowing the lifting frame 100 to engage with it via the inclined surface. When the movable frame 400 moves horizontally, it can drive the lifting frame 100 to move vertically relative to the movable frame 400. Rollers 120 are provided on the lifting frame 100, which move along the guide surface... The rollers 120 rotate at 450 degrees, causing the lifting frame 100 to move vertically. A limiting member 210 is provided on the support frame 200, and a cooperating member is provided on the lifting frame 100. The support frame 200 uses the cooperation between the cooperating member and the limiting member 210 to constrain the lifting frame 100 in the horizontal direction, so that the lifting frame 100 can only move in the vertical direction and cannot move in the horizontal direction. This ensures the reliability of the movement of the lifting frame 100, thereby ensuring the reliability of the micro-lifting mechanism. In this way, while ensuring that the vehicle transport device can reliably transport vehicles from the bottom, it also improves the convenience and reliability of parking vehicles in the buffer parking space.

[0057] like Figure 2 and Figure 3 As shown, the lifting frame 100 is connected to a mating component on the side facing the moving frame 400, and the support frame 200 is provided with a limiting component 210. The limiting component 210 is correspondingly set and cooperates with the mating component to restrict the lifting frame 100 to move only in the vertical direction and prevent the lifting frame 100 from moving in the horizontal direction. This reduces the space occupied by the micro-lifting mechanism in the horizontal direction when the lifting frame 100 is lifting, and ensures the reliable operation of the lifting frame 100.

[0058] In some embodiments, the limiting member 210 is a limiting rod arranged in a vertical direction, and the mating member is two pulleys 140 arranged side by side. The rotation direction of the pulleys 140 is perpendicular to the movement direction of the moving frame 400 in the horizontal plane. The limiting rod is inserted between the two pulleys 140 so that the limiting rod and the two pulleys 140 cooperate with each other.

[0059] By designing the mating parts as two pulleys 140 and the limiting part 210 as a limiting rod, the limiting part 210 is inserted between the two pulleys 140, and the limiting rod is rolledly connected to the two pulleys 140. This reduces the friction between the limiting part 210 and the mating parts, increases the reliability of the movement between the lifting frame 100 and the moving frame 400, thereby increasing the reliability of the micro-lifting mechanism.

[0060] like Figure 4As shown, the support frame 200 is provided with a guide rail 230, which is arranged along the movement direction of the movable frame 400; the movable frame 400 is provided with a slider 430, which slides along the guide rail 230 to guide the movement of the movable frame 400, increase the reliability of the movement of the movable frame 400, and thus ensure the working reliability of the micro-lifting mechanism.

[0061] In some embodiments, such as Figure 4 and Figure 5 As shown, the movable frame 400 is provided with an extension 440, which is located on both sides of the movable frame 400 along its direction of movement. The slider 430 is floatingly connected to the extension 440 by a shoulder screw 500. The slider 430 and the movable frame 400 are not firmly connected, and a certain amount of shaking can occur between them to prevent the slider 430 from getting stuck when sliding along the guide rail 230, which would cause the movable frame 400 to jam and avoid damage to the micro-lifting mechanism.

[0062] like Figure 6 As shown, the micro-lift drive 300 is connected to a screw 310, and the movable frame 400 is provided with a first connecting block 410. The screw 310 is connected to the first connecting block 410 by a thread. The micro-lift drive 300 drives the screw 310 to rotate, and the first connecting block 410 converts the rotation of the screw 310 into linear motion of the first connecting block 410 along a first direction, thereby causing the first connecting block 410 to drive the movable frame 400 to move linearly along the first direction.

[0063] In some embodiments, the first connecting block 410 is connected to the movable frame 400 via a shoulder screw 500, and the shoulder screw 500 is connected to a locking nut 600, so that the first connecting block 410 and the movable frame 400 are floatingly connected. The first connecting block 410 and the movable frame 400 have a certain degree of freedom and can wobble to a certain extent to prevent the movable frame 400 from jamming when the screw 310 moves, thus providing a certain tolerance for the movable frame 400 and the first connecting block 410, thereby ensuring the reliability of the micro-lifting mechanism's movement.

[0064] like Figure 3 As shown, the support frame 200 is connected to a second connecting block 220. The second connecting block 220 and the first connecting block 410 are arranged correspondingly along the length direction of the screw 310. The screw 310 and the second connecting block 220 are rotatably connected so that the second connecting block 220 supports the screw 310, increasing the stability and reliability of the rotation of the screw 310, thereby increasing the stability and reliability of the linear motion of the moving frame 400, and further increasing the reliability of the micro-lifting mechanism.

[0065] In some embodiments, the micro-lift drive 300 is a drive motor.

[0066] like Figure 7As shown, the movable frame 400 is further defined with a support surface extending along the movement direction of the movable frame 400. The support surface is located at the upper and lower ends of the guide surface 450 and is used to support the roller 120. When the lifting frame 100 moves to the extreme position of lifting, the roller 120 contacts the support surface located at the upper end of the guide surface 450. When the lifting frame 100 moves to the extreme position of falling, the roller 120 contacts the support surface located at the lower end of the guide surface 450.

[0067] By providing support surfaces at the upper and lower ends of the guide surface 450, the roller 120 stops on the horizontal surface when the lifting frame 100 moves to the limit position of lifting and the limit position of falling, thus avoiding the roller 120 stopping on the inclined surface. The roller 120 stopping on the horizontal surface can increase the reliability of the roller 120 stopping, thereby increasing the reliability of the movement of the lifting frame 100, and further increasing the reliability of the micro-lifting mechanism.

[0068] For ease of description, the support surface located at the upper end of the guide surface 450 is referred to as the first support surface 420, and the support surface located at the lower end of the guide surface 450 is referred to as the second support surface 480.

[0069] Specifically, the upper end of the guide surface 450 is provided with a first support surface 420. When the lifting frame 100 moves to the extreme position of the lifting, the roller 120 contacts the first support surface 420. The lower end of the guide surface 450 is provided with a second support surface 480. When the lifting frame 100 moves to the extreme position of the falling, the roller 120 contacts the second support surface 480.

[0070] It should be noted that when the roller 120 contacts the first support surface 420, the lifting surface 101 moves to the highest position; when the roller 120 contacts the second support surface 480, the lifting surface 101 moves to the lowest position.

[0071] like Figure 3 As shown, two movable frames 400 are configured, corresponding to opposite ends of the lifting frame 100, to ensure the reliability of the lifting operation of the lifting frame 100. The two movable frames 400 move in opposite directions to reduce the movement distance of the movable frames 400 along the first direction, thereby ensuring the reliability of the micro-lifting mechanism.

[0072] In some embodiments, the two movable frames 400 are driven by the same micro-lift drive 300, which is located between the two movable frames 400 along a first direction and below the lifting frame 100, in order to simplify the micro-lift mechanism, facilitate its arrangement, thereby reducing the number of micro-lift mechanism components and facilitating the production and assembly of the micro-lift mechanism.

[0073] like Figure 2As shown, the lifting frame 100 is provided with a connecting rod 130. The connecting rod 130 is located at the bottom of the lifting frame 100 and protrudes from the bottom surface of the lifting frame 100. It is used to increase the overall connection strength of the lifting frame 100, thereby increasing the stress range of the lifting surface 101 and preventing damage to the lifting frame 100 when the wheel drives into the lifting surface 101. This increases the reliability of the micro-lifting mechanism and further increases the reliability of the micro-lifting mechanism.

[0074] like Figure 7 As shown, the movable frame 400 is provided with a clearance part 470, which is located at the top of the movable frame 400. The clearance part 470 is correspondingly provided with the connecting rod 130 to prevent the connecting rod 130 from interfering with the movable frame 400 when the lifting frame 100 falls.

[0075] like Figure 3 As shown, the movable frame 400 is located inside the support frame 200, and the lifting frame 100 is also located inside the support frame 200 when it descends. The micro-lifting drive component 300 is also located inside the support frame 200 to facilitate the arrangement of the movable frame 400 and the micro-lifting drive component 300, thereby reducing the space occupied by the micro-lifting mechanism.

[0076] It should be noted that when the movable frame 400 moves in a straight line along the first direction, the lifting frame 100 moves synchronously in the vertical direction.

[0077] When the aforementioned micro-lifting mechanism is applied to a multi-level parking garage, objects such as stones carried in the vehicle tires may fall and cause the micro-lifting mechanism to jam, resulting in the lifting frame 100 and the moving frame 400 moving out of sync, causing the lifting frame 100 to be unable to descend in a timely and effective manner.

[0078] In the aforementioned micro-lifting mechanism, by setting an insert 460 in the movable frame 400 and a connector 110 in the lifting frame 100, the insert 460 is inserted into the connector 110. When the lifting frame 100 falls, if the movement of the lifting frame 100 is not synchronized with the movement of the movable frame 400, the insert 460 can apply a downward pulling force to the connector 110, thereby causing the lifting frame 100 to fall, thus ensuring the reliability of the micro-lifting mechanism.

[0079] Specifically, such as Figure 7 As shown, the movable frame 400 is provided with an insert 460, and the lifting frame 100 is provided with a connector 110. The connector 110 is provided with an opening for the insert 460 to be inserted, and the opening is set along the movement direction of the movable frame 400. When the movable frame 400 moves in the opposite direction and the roller 120 disengages from the guide surface 450, the movable frame 400 drives the insert 460 to apply a downward force to the connector 110, thereby lowering the lifting frame 100 and preventing the lifting frame 100 from getting stuck due to falling into stones or other objects and failing to complete the descent.

[0080] like Figure 8 and Figure 9 As shown, the insert 460 is arranged along the movement direction of the movable frame 400, with one end of the insert 460 located on the movable frame 400 and the other end facing the connector 110. Normally, when the movable frame 400 moves in the forward direction, causing the lifting frame 100 to move upward, the insert 460 gradually extends into the connector 110, and there is no interaction between the insert 460 and the connector 110. When the movable frame 400 moves in the reverse direction, causing the lifting frame 100 to move downward, the insert 460 gradually disengages from the connector 110. 10. There is no interaction between the insert 460 and the connector 110; however, when the moving frame 400 moves in the opposite direction and the movement of the lifting frame 100 is not synchronized with the movement of the moving frame 400, that is, the moving frame 400 moves in the opposite direction, but the lifting frame 100 stops moving downward or the downward movement of the lifting frame 100 is too small, so that the movement of the lifting frame 100 does not correspond to the movement of the moving frame 400, the insert 460 will apply a downward pressure force to the connector 110, causing the lifting frame 100 to fall under the action of the downward pressure.

[0081] It should be noted that when the moving frame 400 moves in the reverse direction, the insert 460 only inserts into the connector 110 and the insert 460 does not apply a downward force to the connector 110. However, when the movement of the lifting frame 100 is not synchronized with the movement of the moving frame 400, the roller 120 will disengage from the guide surface 450. At this time, the insert 460 applies a downward force to the connector 110, causing the lifting frame 100 to fall under the action of the downward force, so as to ensure the reliability of the falling of the lifting frame 100.

[0082] The end of the insert 460 facing the connector 110 is a pointed tip, and the insert 460 is defined with a downward pressing surface, which is an upwardly inclined slope. By designing the surface of the insert 460 that applies tension to the connector 110 as an inclined surface, a stable fit clearance is maintained between the insert 460 and the connector 110 when the lifting frame 100 and the moving frame 400 move synchronously. The insert 460 does not apply force to the connector 110. When the lifting frame 100 and the moving frame 400 move asynchronously, the fit clearance between the insert 460 and the connector 110 gradually decreases to 0, and then the insert 460 applies downward pressure to the connector 110 to leave a certain tolerance space for the lifting frame 100 and a certain allowance between the lifting frame 100 and the moving frame 400 to ensure the reliability of the micro-lifting mechanism.

[0083] The working principle of the micro-lifting mechanism will be explained in detail below, taking the linear movement of the movable frame 400 along the first direction as an example. It should be noted that the guide surface 450 is inclined upward in the opposite direction of the first direction. When the movable frame 400 moves in the forward direction of the first direction, the lifting frame 100 rises, and when the movable frame 400 moves in the reverse direction of the first direction, the lifting frame 100 falls.

[0084] The working principle of the above-mentioned micro-lifting mechanism is as follows: When the micro-lifting drive 300 drives the moving frame 400 to move forward in the first direction, the slider 430 slides along the guide rail 230, and the guide surface 450 also moves forward in the first direction. Since the roller 120 is in contact with the guide surface 450, the roller 120 originally tends to move forward in the first direction with the movement of the guide surface 450. However, since the support frame 200 applies a pulling force to the lifting frame 100 through the limiting member 210 and the cooperating member to prevent the lifting frame 100 and the roller 120 from moving horizontally, the roller 120 and the lifting frame 100 cannot move forward in the first direction. The height of the contact position between the guide surface 450 and the roller 120 continuously increases, causing the roller 120 to be lifted, thereby causing the lifting frame 100 to rise in the vertical direction.

[0085] Similarly, when the micro-lifting drive 300 drives the moving frame 400 to move in the opposite direction in the first direction, the slider 430 slides along the guide rail 230, and the guide surface 450 also moves in the opposite direction in the first direction. Since the roller 120 is in contact with the guide surface 450, the roller 120 originally tends to move in the opposite direction in the first direction as the guide surface 450 moves. However, since the support frame 200 applies a pulling force to the lifting frame 100 through the limiting member 210 and the mating member to prevent the lifting frame 100 and the roller 120 from moving horizontally, the roller 120 and the lifting frame 100 cannot move in the opposite direction in the first direction. The height of the contact position between the guide surface 450 and the roller 120 continuously decreases, causing the roller 120 to fall, thereby causing the lifting frame 100 to fall in the vertical direction.

[0086] In the aforementioned micro-lifting mechanism, when the lifting frame 100 moves up and down, only the moving frame 400 moves in a straight line. Furthermore, the dimension of the moving frame 400 along its direction of movement is smaller than the dimension of the lifting frame 100 along its direction of movement. When the moving frame 400 moves in a straight line to lift the lifting frame 100, the dimension of the moving path of the moving frame 400 will not exceed the dimension of the lifting frame 100 in its direction of movement. Therefore, in the aforementioned micro-lifting mechanism, the horizontal space requirement for the lifting frame 100 is small, and the lifting of the lifting frame 100 can be achieved in a confined space.

[0087] like Figures 11-13 As shown, based on the above-mentioned buffer parking space, this utility model also provides a three-dimensional parking garage, which includes the above-mentioned buffer parking space and a vehicle conveying device. The vehicle conveying device can enter and exit the through channel along the extension direction of the through channel to move vehicles from the bottom of the buffer parking space.

[0088] The automated parking system includes an adjustment mechanism 700, which is used to adjust the vehicle body. A support surface 701 is located within the adjustment mechanism 700. Before parking, the vehicle passes through the adjustment mechanism 700 for body adjustment. Then, a vehicle transport device transports the adjusted vehicle to the parking space. Some vehicle transport devices use a supporting method to transport vehicles. Therefore, the adjustment mechanism 700 has a channel 900 in the middle for the vehicle transport device to enter, allowing the device to support the vehicle from below. The existence of the channel 900 increases the difficulty of entering the adjustment mechanism 700, as the vehicle wheels can easily get stuck. A micro-lifting mechanism is installed within the channel 900. When a vehicle needs to enter the adjustment mechanism 700 for body adjustment, the lifting surface 101 rises until it is roughly flush with the placement surface of the adjustment mechanism 700 used to place the vehicle, reducing the difficulty of the vehicle entering the adjustment mechanism 700. After the vehicle body is straightened, the lifting surface 101 is lowered so that the vehicle conveying device can enter the passage 900 to transport the vehicle.

[0089] The vehicle transport device typically needs to move along the guide 800, one end of which extends to the aisle 900 and the other end of which extends to the final parking space of the vehicle, so that the vehicle transport device can reciprocate between the adjustment mechanism 700 and the parking space.

[0090] It should be noted that the specific structures of the adjustment mechanism 700, the vehicle conveying device, and the guide 800 are conventional technical means in this field and will not be described in detail here.

[0091] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0092] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
