Abstract
The utility model discloses a positioning switch structure of a parking stall lock. The positioning switch structure of the parking stall lock aims to solve the problem that due to dust, an existing photoelectric positioning switch of the parking stall lock is prone to ineffective positioning. The positioning switch of the parking stall lock comprises a rotating shaft and a vehicle blocking arm fixed to the rotating shaft. A cam is fixed to the rotating shaft. A magnet is installed at the protruding end of the cam. A Hall element installation plate is arranged on one side of the cam. A lower dead center Hall element is installed at the lower end of the Hall element installation plate. The upper end of the Hall element installation plate is provided with an upper dead center Hall element. At least one transition area Hall element which is installed on the Hall element installation plate is arranged between the lower dead center Hall element and the upper dead center Hall element. The distance between the lower dead center Hall element, the upper dead center Hall element and the transition area Hall element and the axis of the rotating shaft is equal to the distance between the magnet and the axis of the rotating shaft. The positioning switch structure of the parking stall lock is simple in structure, safe and reliable.

Existing berth lock by concave back down microswitch control power transmission shaft rotate drive stop arm overturn, microswitch gets rusty easily, weares and teares, is shifted, the life-span is short.
Chinese patent CN203308148U discloses a kind of berth lock position-sensing switch structure berth lock photoelectricity position-sensing switch assembly, it adopts the parts such as shadow shield, realize contactless position-sensing switch, but because berth lock is generally close to bottom surface, service time, slightly long dust can stop infrared rays, thereby caused the problems such as locate failure, and reliability is not high, and photoelectricity position-sensing switch assembly is also inconvenient to clean, be not easy to penetration and promotion.
Utility model content
In order to overcome existing berth lock photoelectricity position-sensing switch assembly, due to dust, easily deficiency and the microswitch of locate failure get rusty easily, wear and tear, are shifted, the problem that life-span is short, the utility model aims to provide a kind of hardware foundation that berth lock is controlled automatically of realizing, be specially a kind of berth lock position-sensing switch structure, this position-sensing switch structure simple in structure, safe and reliable.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of berth lock position-sensing switch structure, comprises rotating shaft, is fixed on the arm of keeping off a car of rotating shaft; Its design feature is, cam is fixedly housed in described rotating shaft, on the protruding end of this cam, magnet is housed; Described cam one side is equipped with Hall element installing plate, lower dead center Hall element is equipped with in the lower end of this Hall element installing plate, top dead centre Hall element is equipped with in the upper end of this Hall element installing plate, is provided with at least one the transition region Hall element being contained on Hall element installing plate between lower dead center Hall element and top dead centre Hall element; Described lower dead center Hall element, top dead centre Hall element and at least one transition region Hall element are consistent to the distance between rotating shaft core line to the distance between rotating shaft core line and described magnet.
Be below the technical scheme of further improvement of the utility model:
In order to ensure inductive effects better, described cam and Hall element installing plate be arranged in parallel.
Preferably, the distance between described cam and Hall element installing plate is 2mm ~ 4mm.
Further, the line of described lower dead center Hall element, top dead centre Hall element and at least one transition region Hall element is approximate circle camber line.
Generally speaking, described lower dead center Hall element and top dead centre Hall element are only provided with a transition region Hall element.
As a kind of concrete fixed form, described cam is fixed in rotating shaft by holding screw.
Described lower dead center Hall element and rotating shaft are positioned in same level; Described top dead centre Hall element and rotating shaft are positioned on same vertical plane.
By said structure, the utility model applies to Hall element in berth lock control first, utilizes Hall element to coordinate with magnet, provides a kind of extraordinary technological approaches for controlling berth lock.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, safe and reliable, the problem of both having avoided conventional travel switch to damage, and the problem of also having avoided optoelectronic switch easily to lose efficacy, is worthy to be popularized.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
