Description

Technical Field

[0001] The present application relates to the field of stereo garages, and in particular to a vehicle plate anti-retraction mechanism for a stereo garage. Background Art

[0002] Currently, lifting and transversely sliding parking garages are widely used as parking equipment that effectively utilizes space and improves parking efficiency. Due to their relatively low technical requirements, low investment costs, and strong site adaptability, they are widely used. Conventional lifting and transversely sliding parking garages typically have only one row of vehicle decks per floor. When parking or unloading vehicles, the decks only move up and down and laterally. Multi-row lifting and transversely sliding parking garages typically have two rows of vehicle decks per floor. When parking or unloading vehicles, the decks also move longitudinally in addition to their up and down and laterally movements. During the parking and unloading process, when a vehicle is parked or unloaded, the inertia of the vehicle can cause the decks to shift longitudinally, potentially leading to collisions with other decks on the same train and accidents. Therefore, installing a plate retaining mechanism is extremely important.

[0003] In the related technology, a Chinese utility model with authorization announcement number CN211818407U discloses a longitudinal movement stop device for a three-dimensional parking garage, including a base plate, an axle seat is fixedly provided on the base plate, a pin shaft extending forward and backward in the horizontal direction is installed on the axle seat, and the pin shaft and the axle seat are fixed in position by a first cylindrical pin, and a stop block and a torsion spring are respectively sleeved on the pin shaft, and one end of the torsion spring is fixedly connected to the stop block, and the other end of the torsion spring is fixedly connected to the base plate, and a shaft sleeve is fixed on the stop block, a support shaft is embedded in the shaft sleeve, and the support shaft and the shaft sleeve are fixed in position by a second cylindrical pin.

[0004] However, due to the structural design problem of the anti-recognition mechanism, when the vehicle stops and the vehicle plate needs to move normally longitudinally, a large amount of power is required to drive the pulley on the vehicle plate to impact the anti-recognition block to make the vehicle plate break away from the limit of the anti-recognition device. Long-term use may easily lead to damage to the anti-recognition device or the vehicle plate, resulting in economic losses. Utility Model Content

[0005] In order to help solve the problem that the anti-recoil mechanism may cause damage to the anti-recoil device or the vehicle plate after long-term use, resulting in economic losses, the present application provides a vehicle plate anti-recoil mechanism for a three-dimensional parking garage.

[0006] The present application provides a three-dimensional garage vehicle plate anti-retraction mechanism adopts the following technical solutions:

[0007] A vehicle plate stop mechanism for a multi-story parking garage includes a stop plate, a positioning shaft, and a driving device. The positioning shaft is rotatably connected to the vehicle plate, and the rotation axis of the positioning shaft is parallel to the lateral movement direction of the vehicle plate. The driving device is used to drive the positioning shaft to rotate so that the stop end of the positioning shaft and the stop plate are offset. The positioning shaft can rotate under the action of gravity so that the stop end of the positioning shaft and the stop plate are arranged relative to each other.

[0008] By adopting the above technical solution, when the vehicle enters the vehicle plate, the positioning shaft rotates under the action of gravity, and the stop end is arranged relative to the blocking surface of the stop fixing plate. When the vehicle plate is displaced longitudinally, the stop end abuts against the blocking surface of the stop fixing plate to prevent backward movement. After the vehicle stops, the driving assembly drives the positioning shaft to rotate so that the stop end of the positioning shaft and the stop fixing plate are staggered, and the vehicle plate can move normally, reducing the collision between components and improving the stability and durability of the stop mechanism.

[0009] Optionally, a roller is provided at the stop end of the positioning shaft, the rotation axis of the roller is perpendicular to and intersects with the rotation axis of the positioning shaft, and the rolling surface of the roller can roll and abut against the blocking surface of the stop fixing plate.

[0010] By adopting the above technical solution, the roller abuts against the blocking surface of the anti-recognition fixing plate when the vehicle plate is displaced longitudinally, and the rolling contact between the roller and the anti-recognition fixing plate can significantly reduce the friction between the anti-recognition end of the positioning shaft and the blocking surface of the anti-recognition fixing plate when the positioning shaft rotates, thereby achieving smooth rotation, and when the vehicle plate is subjected to a large impact force, the roller will roll along the blocking surface of the anti-recognition fixing plate to make the anti-recognition end of the positioning shaft and the anti-recognition fixing plate staggered, thereby preventing damage to the anti-recognition mechanism.

[0011] Optionally, the stop end of the positioning shaft is provided with an abutment block, the abutment surface of the abutment block is parallel to the blocking surface of the stop fixing plate, and the abutment surface of the abutment block can abut against the blocking surface of the stop fixing plate.

[0012] By adopting the above technical solution, the abutment surface of the abutment block abuts against the blocking surface of the anti-recoil fixing plate when the vehicle plate is longitudinally displaced, thereby increasing the force-bearing area, preventing the positioning shaft from rotating when impacted, providing effective anti-recoil for the vehicle plate, and making the anti-recoil mechanism more stable.

[0013] Optionally, the abutment block is made of soft material.

[0014] By adopting the above technical solution, the stop block made of soft material can provide a certain buffering and shock absorption effect when the abutting surface of the abutting block abuts against the blocking surface of the stop fixing plate, while also reducing noise during operation.

[0015] Optionally, the size of the positioning shaft gradually increases in a direction away from the stop end, and the driving device includes a telescopic member, and the output end of the telescopic member can be slidably abutted against the outer wall of the positioning shaft.

[0016] By adopting the above technical solution, the output end of the telescopic part in the driving device can slide and abut against the outer wall of the positioning shaft, thereby realizing smooth rotational drive, ensuring that the positioning shaft can accurately cooperate with the anti-retreat fixing plate during the anti-retreat process, and improving the anti-retreat effect and stability.

[0017] Optionally, a guide wheel is installed at the output end of the telescopic member, and the guide wheel is in rolling contact with the outer wall of the positioning shaft.

[0018] By adopting the above technical solution, the friction between the output end of the telescopic member and the outer wall of the positioning shaft can be effectively reduced, the action efficiency of the drive device and the smoothness of the positioning shaft rotation can be improved, and the service life of the mechanism can be extended.

[0019] Optionally, one end of the positioning shaft far from the stop end is provided with an arc surface, and the arc surface can be slidably abutted against the output end of the telescopic member.

[0020] By adopting the above technical solution, when the telescopic part pushes the positioning shaft to rotate, its movement is ensured to be smoother and more stable, reducing the jamming when the output end of the telescopic part abuts against the outer wall of the positioning shaft due to the ridges generated by the intersection of planes, thereby extending the service life of the entire anti-retraction mechanism.

[0021] Optionally, the telescopic member is one of an electric push rod, a cylinder, and a hydraulic cylinder.

[0022] By adopting the above technical solution, the electric push rod, air cylinder and hydraulic cylinder can all stably and reliably drive the positioning shaft to rotate and realize the anti-retraction function, and the three are commonly used standard parts, which are convenient for maintenance and replacement.

[0023] Optionally, a buffer pad is provided on the blocking surface of the retreat-stopping fixing plate.

[0024] By adopting the above technical solution and arranging a buffer pad on the blocking surface, a certain buffering and shock-absorbing effect can be provided when the abutting surface of the abutting block abuts the blocking surface of the retaining fixed plate, while also reducing noise during operation.

[0025] Optionally, a weight-reducing hole is provided on a side of the positioning shaft away from the stop end.

[0026] By adopting the above technical solution, the weight-reducing holes are used to balance the two ends of the positioning shaft, so that the positioning stop end can quickly rotate to a position opposite to the stop fixing plate under the action of gravity.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the vehicle plate is displaced longitudinally, the roller abuts against the blocking surface of the anti-retraction fixing plate. The rolling contact between the roller and the anti-retraction fixing plate can significantly reduce the friction between the anti-retraction end of the positioning shaft and the blocking surface of the anti-retraction fixing plate when the positioning shaft rotates, thereby achieving smooth rotation. Moreover, when the vehicle plate is subjected to a large impact force, the roller will roll along the blocking surface of the anti-retraction fixing plate to misalign the anti-retraction end of the positioning shaft and the anti-retraction fixing plate, thereby preventing damage to the anti-retraction mechanism.

[0029] 2. When the vehicle plate is displaced longitudinally, the roller abuts against the blocking surface of the anti-retraction fixing plate. The rolling contact between the roller and the anti-retraction fixing plate can significantly reduce the friction between the anti-retraction end of the positioning shaft and the blocking surface of the anti-retraction fixing plate when the positioning shaft rotates, thereby achieving smooth rotation. Moreover, when the vehicle plate is subjected to a large impact force, the roller will roll along the blocking surface of the anti-retraction fixing plate to misalign the anti-retraction end of the positioning shaft and the anti-retraction fixing plate, thereby preventing damage to the anti-retraction mechanism.

[0030] 3. The output end of the telescopic member in the drive device can slide and abut against the outer wall of the positioning shaft, thereby achieving smooth rotational drive and ensuring that the positioning shaft can accurately cooperate with the anti-retraction fixing plate during the anti-retraction process, thereby improving the anti-retraction effect and stability;

[0031] 4. The guide wheel can effectively reduce the friction when the output end of the telescopic member abuts against the outer wall of the positioning shaft, improve the action efficiency of the drive device and the smoothness of the rotation of the positioning shaft, and extend the service life of the mechanism.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-4 This application is described in further detail.

[0038] The embodiment of the present application discloses a vehicle plate anti-retraction mechanism for a stereo garage.

[0039] Example 1

[0040] Reference Figure 1 and Figure 2 The anti-recognition mechanism of the vehicle plate of the three-dimensional parking garage includes a anti-recognition fixing plate 1, a positioning shaft 2 and a driving device. In this embodiment, the anti-recognition fixing plate 1 is made of metal material as a whole and is fixed to the ground 6 by expansion bolts. The blocking surface of the anti-recognition fixing plate 1 is perpendicular to the ground 6 and the longitudinal movement direction of the vehicle plate 100. A buffer pad 11 for buffering and shock absorption is provided on the blocking surface of the anti-recognition fixing plate 1. The buffer pad 11 is made of rubber as a whole. In other embodiments, the anti-recognition fixing plate 1 can also be bolted or welded to the bottom plate of the three-dimensional parking garage, and the buffer pad 11 can be made of plastic.

[0041] Reference Figure 1 and Figure 2 In this embodiment, the positioning shaft 2 is made of metal material as a whole and is rotatably connected to the vehicle plate 100 through a rotating shaft 3 fixed on the side of the vehicle plate 100. The rotation axis of the positioning shaft 2 is parallel to the lateral movement direction of the vehicle plate 100. The positioning shaft 2 rotates under the action of its own gravity so that the stop end of the positioning shaft 2 is arranged opposite to the abutting surface of the stop fixing plate 1. The stop end of the positioning shaft 2 is provided with a roller 22. The rotation axis of the roller 22 is perpendicular to and intersects with the rotation axis of the positioning shaft 2. The rolling surface of the roller 22 can roll and abut against the blocking surface of the stop fixing plate 1.

[0042] Reference Figure 1 The end of the positioning shaft 2 away from the stop end is a cam 21, and the size of the cam 21 gradually increases in the direction away from the stop end. The positioning shaft 2 is provided with a weight-reducing hole 211 which runs through the positioning shaft 2 at one end of the cam 21, which is used to reduce the weight of the cam 21 end of the positioning shaft 2, so that the positioning shaft 2 rotates under the action of its own gravity so that the stop end and the abutting surface of the stop fixing plate 1 are arranged relative to each other, so that when the vehicle plate 100 is subjected to a large impact force, the roller 22 will roll along the blocking surface of the stop fixing plate 1 so that the stop end of the positioning shaft 2 and the stop fixing plate 1 are misaligned to prevent damage to the stop mechanism.

[0043] Reference Figures 1 to 3 In this embodiment, the rotating shaft 3 passes through the positioning shaft 2 and is abutted against a baffle 31 at one end away from the vehicle plate 100 to prevent the positioning shaft 2 from sliding. The baffle 31 is fixed to the end of the rotating shaft 3 by bolts.

[0044] In this embodiment, the drive device includes a telescopic member 4, which is an electric push rod 41. The base 411 of the electric push rod 41 is fixed to the side of the vehicle plate 100 and its axis is parallel to the ground 6. The output end of the electric push rod 41 is a push rod 412. The push rod 412 can be pushed in a direction perpendicular to the longitudinal movement of the vehicle plate 100. The top of the push rod 412 is provided with a guide wheel 5. The guide wheel 5 is fixed to the top of the push rod 412 by a pin 7 and a cotter pin 8. The rolling surface of the guide wheel 5 rolls against the outer edge contour surface of the cam 21. When the push rod 412 is pushed, the rolling surface of the guide wheel 5 can roll on the outer edge contour surface of the cam 21. When the push rod 412 is pushed, the rolling surface of the guide wheel 5 can roll on the outer edge contour surface of the cam 21. When the positioning shaft 2 rotates counterclockwise, the stop end of the positioning shaft 2 and the abutment surface of the stop plate 1 are offset. In other embodiments, the drive device can also be a power device such as a motor that can drive the positioning shaft 2 to rotate. The telescopic member 4 can also be a cylinder or a hydraulic cylinder. The drive device can also drive the stop end of the positioning shaft 2 to be arranged relative to the abutment surface of the stop plate 1.

[0045] The implementation principle of Example 1 is as follows: when the vehicle enters the vehicle plate 100, the positioning shaft 2 rotates under the action of its own gravity so that the stop end and the abutment surface of the stop fixing plate 1 are arranged relative to each other, so as to limit the longitudinal displacement of the vehicle plate 100 and achieve the purpose of stopping the vehicle plate 100; when the vehicle stops and needs to move longitudinally normally, the push rod 412 of the electric push rod 41 is pushed out, and the guide wheel 5 at the top end of the push rod 412 rolls and abuts the cam 21 at the cam 21 end of the positioning shaft 2, so that after the positioning shaft 2 rotates, the stop end of the positioning shaft 2 is staggered with the abutment surface of the stop fixing plate 1; the setting of the roller 22 can make the positioning shaft 2 rotate and staggered with the stop fixing plate 1 when the vehicle plate 100 receives a large impact force, thereby preventing damage to the stop mechanism; the driving device adopts the electric push rod 41 to improve the degree of automation of the system, and the design of the weight reduction hole 211 and the cam 21 improves the stability of the structure and the flexibility of the rotation of the positioning shaft 2.

[0046] Example 2

[0047] Reference Figure 4 The difference between this embodiment and embodiment 1 is that an abutment block 23 is provided at the stop end of the positioning shaft 2 .

[0048] In this embodiment, the abutment block 23 is made of nylon material as a whole, and the abutment surface of the abutment block 23 is parallel to the blocking surface of the anti-retreat fixing plate 1. The abutment surface of the abutment block 23 can abut against the blocking surface of the anti-retreat fixing plate 1. In other embodiments, the abutment block 23 can be made of rubber or metal.

[0049] The advantages of Example 2 compared to Example 1 are: compared with the roller 22, the abutment block 23 increases the force-bearing area when abutting against the anti-recoil fixed plate 1, can withstand a larger impact force and can prevent the positioning shaft 2 from rotating when impacted, providing an effective anti-recoil for the vehicle plate 100 and making the anti-recoil mechanism more stable.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
