The utility model another embodiment provides a kind of folding electric door, refers to Figure 13, Figure 13 is the utility model The structural representation of the preferred embodiment of folding electric door one, wherein, the folding electric door includes door body 1 and door lifter 10。

Specifically, the door body 1 includes at least two sections of door body units, wherein, only with two sections of door body in the present embodiment diagram Exemplified by unit (11,12).Adjacent door body unit is rotatablely connected between (11,12), so that electrically operated gate is in switching process, door body list It can be relatively rotated with respect to each other between member to side is adjacent stacked or bending stacked relationship at an angle.

Preferably, the bottom of the door body unit of door body overall structure one end at least when positioned at electrically operated gate the fully extended state Portion is provided with door lifter, is to install door lifter 10 in the bottom of a door body unit 12 in the present embodiment, certainly, in other implementations Door lifter can also be respectively mounted in example in the bottom of each door body unit.Wherein, the quantity of door lifter be more preferably at least two or Person's even number, and the bottom of door body unit is symmetrically arranged at, it is the structure of two door lifters 10 of installation in the present embodiment diagram.

Door lifter 10 is arranged on the door body unit of electrically operated gate by door lifter 10 by the central shaft (i.e. installation axle) of stator, Connected mode on the concrete structure of door lifter 10 and between door body, refer to associated description in above-described embodiment.

And the side of the door body unit (i.e. 11 door body unit in figure) positioned at the overall structure other end of door body 1 is fixed with door body Can be rotation connection between device 2, or be fixedly connected；Wherein, door body fixing device 2 can be wall end or Column door is first-class.When the side of door body unit is rotation connection with door body fixing device 2, can have door body structure 1 Bigger enabling scope, you can so that door body 1 can be achieved to intercept beating completely for region to electrically operated gate in the state of complete fold Open.

Door lifter 10 in the present embodiment is preferably that periphery sets the wheel rim of Mecanum wheel or the wheel rim of omni-directional wheel Structure type, can be by rolling according to the design feature of the wheel rim of Mecanum wheel or the wheel rim of omni-directional wheel with installation ground Dynamic friction, and then drive door body 1 to carry out folding withdrawal or opening action, with by changing the folded state of door body unit come real Now to the control of electronic door opening and closing state.

Wherein, door lifter 10 is driving door body 1 to be folded or during opening action, can be by controlling both sides Mike to receive The rotation direction of the wheel rim of nurse wheel or the rim construction door lifter of omni-directional wheel, make track of the door lifter 10 along similar continuous S types Motion, will be determined, this area on specific operation angle and track according to information such as the length of each door body unit Technical staff can obtain the running orbit of the information and reasonably optimizing door lifter 10, to control door lifter 10 to drive door body 1 to carry out Withdrawal or opening action are folded, is no longer described in detail herein.

When door body structure 1 includes multistage door body unit, one section of door body 1 or the bottom of multistage door body unit can be with Provided with sliding support wheel 101, sliding support wheel 101 is for from middle part, body structure 1 to be played a supporting role on the door.Wherein, the slip Support wheel 101 is specifically as follows universal wheel or global wheel etc..And the specific installation site of sliding support wheel 101 can be door body One end of at least side door body unit bottom at link position between unit, that is, the position in embodiment is illustrated, certainly, Sliding support wheel 101 can also be installed on any position of door body unit bottom in other embodiment, as long as support can be played And slip effect.

The folding electric door provided in the present embodiment, its one end is by setting the wheel rim or complete with Mecanum wheel To the door lifter of the rim construction of wheel, and control the running orbit of door lifter, you can realize that folding switch door acts；Compared to On the one hand traditional structure of folding door, the technical scheme in the present embodiment enormously simplify the structure of folding door drive part, separately On the one hand service life (the knot especially compared to motor at door body unit link position of folding door can be improved Configuration formula), while the cost of product is also reduced, there is good market popularization value.
