Description

Technical Field

[0001] The utility model belongs to the technical field of stereo garages, and in particular relates to a connecting rod driven foldable car blocking device. Background Art

[0002] At present, at the vehicle entrance and exit of a multi-story parking garage, the vehicle wheels need to be blocked when the vehicle enters to achieve vehicle positioning. When the vehicle needs to be moved to a parking space, the vehicle needs to be released. Therefore, the vehicle blocking at the vehicle entrance and exit usually requires a movable structure. The existing vehicle blocking structure is commonly a liftable structure. Specifically, a power element is used to drive a car blocking rod. The power element is commonly a lifting cylinder or a hydraulic cylinder or a gear rack driven by a reduction motor to achieve the lifting of the car blocking rod to block the vehicle wheels. The force of the wheel acts on the car blocking rod, and in this structure, the car blocking rod is directly connected to the piston rod of the cylinder or the hydraulic cylinder, or the car blocking rod is directly connected to the rack. The force of the wheel acts on these power elements, causing the power elements to bear loads for a long time and affecting their service life. In addition, because this structure requires a lifting height, the overall height of the structure is relatively large, and a large space is occupied, resulting in a large thickness of the vehicle entrance and exit mechanism.

[0003] Therefore, in the field of stereo garage technology, there is still a need for research and improvement on the connecting rod driven foldable car blocking device, which is also a research hotspot and focus in the current field of stereo garage technology, and is also the starting point for the completion of the present utility model. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is: to provide a connecting rod driven foldable car arresting device to solve the technical problem that the wheel force acts on the power element and affects the service life of the power element.

[0005] To solve the above technical problems, the technical solution of the utility model is: a connecting rod driven foldable car-blocking device, comprising a mounting arm, on which a car-blocking rod is rotatably mounted via a first hinge shaft, a torque driving mechanism is mounted on the mounting arm, on which a transmission shaft is rotatably mounted, a first connecting rod is fixedly mounted on the transmission shaft, the first connecting rod is hinged to the second connecting rod via a second hinge shaft, the second connecting rod is hinged to the car-blocking rod via a third hinge shaft, the axes of the first hinge shaft, transmission shaft, second hinge shaft and third hinge shaft are all arranged in parallel, and the power output shaft of the torque driving mechanism is transmission-connected to the transmission shaft.

[0006] As an improvement, a supporting roller is rotatably mounted on the end of the vehicle blocking rod.

[0007] As a further improvement, the third hinge shaft is located between the supporting roller and the first hinge shaft.

[0008] As a further improvement, the torque driving mechanism is a reduction motor, and the power output shaft of the reduction motor is connected to the transmission shaft through a gear pair.

[0009] After adopting the above technical solution, the beneficial effects of the utility model are:

[0010] (1) The utility model provides a connecting rod driven foldable car-blocking device, in which the force of the car-blocking rod acts on the mounting arm, and the torque drive mechanism is no longer subjected to wheel pressure, thereby making the drive smoother and extending the service life of the torque drive mechanism. In addition, the structure can drive the first connecting rod to overlap the first connecting rod, the second connecting rod and the car-blocking rod with the mounting arm, thereby greatly reducing the occupied space.

[0011] (2) Since the end of the car stopper rod is rotatably mounted with a supporting roller, the direction of the bearing force of the car stopper rod is consistent with the radial direction of the supporting roller. On the one hand, the end of the car stopper rod is supported to form a supporting beam, and the force is more reasonable. On the other hand, the supporting roller supports the car stopper rod, making the swing of the car stopper rod smoother. BRIEF DESCRIPTION OF THE DRAWINGS

Specifically, the torsion drive mechanism is a reduction motor 8, and the power output shaft of the reduction motor 8 is connected to the transmission shaft 9 through a gear pair. The gear pair includes a driving gear 11 fixedly mounted on the power output shaft of the reduction motor 8 and a driven gear 12 fixedly mounted on the transmission shaft 9 through a key bar. The driving gear 11 is meshed with the driven gear 12, and the reciprocating rotation of the reduction motor 8 drives the first connecting rod 4 to swing back and forth, thereby driving the car blocking rod 3 to expand and close.
