Description

Technical Field

[0001] This utility model belongs to the field of parking equipment, specifically relating to a synchronous push rod type safety centering system for mechanical parking equipment. Background Technology

[0002] Mechanical parking systems, through their three-dimensional spatial layout and mechanical moving mechanisms, can significantly increase parking capacity within a limited area, making them one of the core infrastructure solutions to urban parking difficulties. When parking, vehicles need to be driven onto the entry / exit platform of the mechanical parking system. A centering system then centers the car to prevent collisions between the vehicle and the parking system structure during movement, or to prevent the vehicle's center of gravity from shifting off-center from the mechanical moving mechanism, which could lead to excessive localized loads on the mechanism.

[0003] Currently, most mechanical parking systems on the market use independent drives for centering the front and rear wheels, with the front and rear centering rods being separate structures. This lacks a synchronization mechanism and cannot eliminate the cumulative deviations caused by signal delays and power mismatches, ultimately resulting in incomplete correction and the vehicle remaining in a tilted state. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a synchronous push rod type safety centering system for mechanical parking equipment, which can simultaneously correct the position of the front and rear wheels of a vehicle to ensure the precise centering of the vehicle on the entry and exit platform.

[0005] The specific technical solution adopted in this utility model is as follows: A synchronous push rod type safety centering system for mechanical parking equipment is installed on an access platform on the ground. The key feature is that the centering system includes a motor and a pair of spaced-apart centering tubes. The motor is installed on the access platform, and the centering tubes are respectively located on the left and right sides of the access platform. The left and right centering tubes are synchronously driven by the motor through a transmission component. The centering tubes have the freedom to move in opposite directions driven by the motor. The front and rear parts of the centering tubes abut against the front and rear wheels of the vehicle, respectively. The centering tubes are also equipped with proximity switches for the front and rear wheels.

[0006] The transmission assembly includes a gear and a rack. The gear is connected to the power output shaft of the motor. The centering tube is connected to the fixed end of the rack. The overhanging ends of the rack are all set to overhang towards the gear and mesh with the gear for transmission. The ground is provided with guide wheels that form a sliding engagement with the rack.

[0007] A connecting plate and a transmission square steel are sequentially arranged between the fixed ends of the centering tube and the rack. The fixed ends of the centering tube and the rack are connected by the connecting plate and the transmission square steel. A linear guide rail is also provided on the ground. The transmission square steel is guided and connected to the linear guide rail by a slider. A clearance groove for the connecting plate is provided on the entry and exit platform.

[0008] Two sets of transmission components are provided between the centering tubes, and the two sets of transmission components are spaced apart along the front and rear direction of the centering tubes.

[0009] The centering tube is provided with impact blocks at its front and rear ends, and the centering tube abuts against the front and rear wheels of the vehicle by means of the impact blocks.

[0010] The centering tube has a mounting block protruding towards the vehicle's location. The upper end of the impact block is hinged to the mounting block via a hinge shaft. The proximity switches are located below the hinge shaft and spaced apart from the impact block. The axial direction of the hinge shaft is parallel to the front-rear direction of the centering tube. The centering tube also has a reset assembly for the impact block. The lower end of the impact block is tilted towards the vehicle's location via the reset assembly.

[0011] The reset assembly includes a spring-loaded push rod. The sliding end of the push rod has a degree of freedom to slide on the centering tube, and the actuating end of the push rod extends over the impact block. The push rod resets the impact block by means of the spring.

[0012] The length of the impact block at the rear of the centering tube is greater than the length of the impact block at the front of the centering tube.

[0013] The beneficial effects of this utility model are: This utility model uses a single power source to drive the movement of two centering tubes, ensuring that the left and right centering tubes move synchronously. The front and rear parts of the centering tubes are as a whole, so the front and rear parts of the centering tubes move synchronously. The centering tubes synchronously correct the front and rear wheels of the vehicle, ensuring that the front and rear wheels are in the same position. This effectively avoids the tilting of the vehicle body caused by the asynchronous correction of the front and rear wheels, and ensures that the vehicle is accurately centered.

[0014] The centering tube is also equipped with proximity switches for the front and rear wheels. When all four proximity switches are triggered during the centering process, it indicates that the centering is complete, thus achieving precise control of the centering process and accurate correction of the vehicle.

[0015] One rack connected to the centering tube is located above the gear and meshes with the gear, while the other rack connected to the centering tube is located below the gear and meshes with the gear. Under the action of the motor, the rotation of the gear can drive the two racks to move towards each other or in opposite directions. During the movement of the racks, the centering tube moves synchronously, thereby realizing the centering of the vehicle and the reset of the centering tube. The structure is simple and can realize the synchronous action of the centering tube.

[0016] During the centering process and the centering tube reset, the impact block gradually separates from the wheel, and the reset component pushes the impact block to move, thus achieving automatic reset of the impact block.

[0017] The length of the impact block at the rear of the centering tube is greater than that at the front of the centering tube, which can adapt to centering operations of vehicles with different wheelbases and has a wider range of applications. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Specific implementation examples Figure 1 , Figure 2 As shown, a synchronous push rod type safety centering system for mechanical parking equipment includes a motor 1 and a pair of spaced-apart centering tubes 2. The motor 1 is mounted on an access platform 8, which is installed on the ground. The centering tubes 2 are respectively located on the left and right sides of the access platform 8. The two pairs of centering tubes 2 are synchronously driven by the motor 1 through a transmission component 3. The centering tubes 2 have the freedom to move in opposite directions with the drive of the motor 1. The front and rear parts of the centering tubes 2 abut against the front and rear wheels of the vehicle, respectively. That is, the front part of the centering tube 2 on the left side of the access platform 8 acts on the left front wheel of the vehicle and the rear part acts on the left rear wheel of the vehicle, and the front part of the centering tube 2 on the right side of the access platform 8 acts on the right front wheel of the vehicle and the rear part acts on the right rear wheel of the vehicle.

[0020] After the vehicle is parked on the access platform 8, the same motor 1 drives the two centering tubes 2 on the left and right to move towards each other through the transmission component 3. The single power source ensures that the two centering tubes 2 move synchronously. The front and rear of the centering tube 2 are as a whole, so the front and rear of the centering tube 2 move synchronously. The centering tube 2 synchronously corrects the front and rear wheels of the vehicle, ensuring that the front and rear wheels are in the same position. This effectively avoids the tilt of the vehicle body caused by the asynchronous correction of the front and rear wheels, and ensures that the vehicle is accurately centered.

[0021] The centering tube 2 is also equipped with proximity switches 4 for the front and rear wheels. When all four proximity switches 4 are triggered during the centering process, it indicates that the centering is complete, thus achieving precise control of the centering process and accurate correction of the vehicle.

[0022] like Figure 3 , Figure 5 As shown, the transmission assembly 3 includes a gear 301 and a rack 302. The gear 301 is connected to the power output shaft of the motor 1. The centering tube 2 is connected to the fixed end of the rack 302. The overhanging ends of the rack 302 are all overhanging towards the gear 301 and meshing with the gear 301 for transmission. Specifically, the axial direction of the gear 301 is parallel to the front-rear direction of the entry / exit platform 8. One rack 302 connected to the centering tube 2 is located above the gear 301 and meshes with the gear 301. The other rack 302 connected to the centering tube 2 is located below the gear 301 and meshes with the gear 301. The rotation of the gear 301 can drive the two racks 302 to move towards each other or in opposite directions. During the movement of the racks 302, the centering tube 2 moves synchronously, thereby realizing the centering of the vehicle and the reset of the centering tube 2.

[0023] A guide wheel 303 is provided on the ground to guide the rack 302. The guide wheel 303 guides the rack 302 to prevent the rack 302 from deviating, thereby ensuring the positional accuracy of the proximity switch 4 and the wheel.

[0024] A connecting plate 304 and a transmission square steel 305 are sequentially arranged between the fixed end of the centering tube 2 and the rack 302. The fixed ends of the centering tube 2 and the rack 302 are connected by the connecting plate 304 and the transmission square steel 305. A linear guide rail 306 is also provided on the ground. The transmission square steel 305 is connected to the linear guide rail 306 by means of a slider, which further prevents the centering tube 2 from shifting position and ensures the positional accuracy of the proximity switch 4 and the wheel, so that the proximity switch 4 is triggered when the wheel is aligned. The entry / exit platform 8 is provided with a clearance groove for the connecting plate 304.

[0025] Two sets of transmission components 3 are provided between the centering tubes 2. The two sets of transmission components 3 are spaced apart along the front and rear direction of the centering tubes 2. The gears 301 of the two transmission components 3 are coaxially fixed to the drive shaft 9. The gears 301 are connected to the power output shaft of the motor through the drive shaft 9, so as to realize the synchronous operation of the two sets of transmission components 3. The connecting plate 304 in the two transmission components 3 provides stable support for the centering tubes 2, preventing the centering tubes 2 from being too long and causing vibration or deflection, and further improving the centering accuracy.

[0026] Preferably, the center tube 2 is provided with impact blocks 5 at the front and rear parts respectively, and the center tube 2 abuts against the front and rear wheels of the vehicle by means of the impact blocks 5.

[0027] like Figure 4 As shown, a mounting block 6 protrudes from the centering tube 2 toward the vehicle's location. The upper end of the impact block 5 is hinged to the mounting block 6 via a hinge shaft 501. Proximity sensors 4 are located below the hinge shaft 501 and spaced apart from the impact block 5. The axial direction of the hinge shaft 501 is parallel to the front-rear direction of the centering tube 2. A reset assembly 7 for the impact block 5 is also provided on the centering tube 2. The lower end of the impact block 5 is tilted toward the vehicle's location via the reset assembly 7. When the centering tube 2 moves toward the vehicle, the lower end of the impact block 5 contacts the wheel first. As the centering tube 2 continues to move, it pushes the vehicle to center. The impact block 5 rotates around the hinge shaft 501 due to the reaction force of the wheel. The lower end of the impact block 5 moves toward the proximity switch 4 and triggers the proximity switch 4. When all four proximity switches 4 are triggered, it indicates that the centering is complete, and the motor 1 stops working.

[0028] The reset assembly 7 includes a guide block 701, a push rod 702, a stop sleeve 703, and a spring 704. The guide block 701 has a guide hole perpendicular to the front-rear direction of the centering tube 2 and horizontally positioned. The guide block 701 is fixed to the centering tube 2. The sliding end of the push rod 702 guides and engages with the guide block 701. The actuating end of the push rod 702 extends towards the impact block 5 and abuts against the impact block 5 via a pulley 705. The impact block 5 has a tubular structure and a notch for the pulley 705 to enter and exit. Preferably, the pulley 705 is a bearing bolt. When the impact block 5 rotates around the hinge shaft 501 under the reaction force of the wheel, the arc surface of the bearing bolt... The inner wall of the impact block 5 is in contact with the impact block 5 to reduce friction on the impact block 5; the stop sleeve 703 is installed on the push rod 702 and located between the action end and the guide end; the spring 704 is fitted on the push rod 702 and located between the stop sleeve 703 and the guide block 701. When the impact block 5 rotates around the hinge shaft 501 under the reaction force of the wheel, the impact block 5 abuts against the pulley 705 and pushes the push rod 702 backward, the spring 704 is compressed. During the process of centering and centering tube 2 resetting, the impact block 5 gradually separates from the wheel, the pressure on the spring 704 decreases, the spring 704 resets and pushes the push rod 702 and the impact block 5 to move, so as to realize the automatic reset of the impact block 5.

[0029] Preferably, the length of the impact block 5 at the rear of the centering tube 2 is greater than the length of the impact block 5 at the front of the centering tube 2, which can adapt to the centering operation of vehicles with different wheelbases and has a wider range of applications.
