Problems solved by technology

The electric folding door is composed of multiple fixed-width door frames hinged by the machine head. After the door is opened, all the door frames are folded together vertically; Folding or unfolding in one direction, so as to realize the opening and closing of the door. After folding, it occupies a small space and is suitable for many occasions; In a straight line, each hinge will be at the dead point position. At this time, the machine head will drive the door to open again, and it will not be able to apply lateral thrust to the door frame to release the dead point, and the door cannot be closed smoothly; therefore, it is necessary to add a side thrust of the door frame to the driving position of the machine head. mechanism to release the hinged dead point of opening the door; however, this type of machine head drive structure is complex and has a high failure rate, and it cannot be fully matured for market application at present.

Embodiment 1

[0038] A kind of omnidirectional traction mechanism structure form of the present invention is introduced in this embodiment, see figure 1 and figure 2 , the base plate assembly includes a support base plate 1 and a head base plate 2, the support base plate 1 is fixedly arranged at the lower end of the machine head housing, a pair of long grooves are opened on the support base plate 1, and two pieces of machine head base plates 2 are respectively arranged in the long grooves, A bearing fixing frame 5 is arranged in the center of the support base plate 1, and a rotating shaft support 4 is arranged on the two machine head base plates 2. The two ends of the machine head bottom plate 2 can be turned up and down relative to the plane of the support bottom plate 1 through the bearings passing through the bearing fixing frame 5; the mecanum wheel assembly includes four sets of independent mecanum wheel units, each Both ends of the bottom plate 2 are provided with a group of indepen...

Embodiment 2

[0042] Another omnidirectional traction mechanism structural form of the present invention is introduced in this embodiment, see image 3 and Figure 4, and the difference from Embodiment 1 is that two head base plates 2 are arranged laterally, and two sets of mecanum wheel units on the same side along the horizontal axis of the support base plate 1 are arranged on one head base plate 2 . When the four sets of mecanum wheel units pass through rough and uneven roads, the nose base plate 2 can deflect at a certain angle to always ensure that the four sets of mecanum wheel units can be in close contact with the ground and will not hang in the air, so that the nose can be accurately Omni-directional movement, the door can be opened and closed smoothly.

Embodiment 3

[0044] The selection of the door body in this embodiment is an electric telescopic door body, see Figure 5 , including machine head, door body and fixed shaft, the machine head is fixedly connected with the door body, the tail of the door body is hinged with the fixed shaft, and the machine head with door body can rotate around the fixed shaft. The omnidirectional traction mechanism is installed in the machine head. When the machine head drives the door body to stretch, the electronic control system controls the traction mechanism in the machine head to move horizontally to the left to complete the door closing action, such as Figure 5 As shown; when the machine head drives the door body to retract, the electronic control system controls the traction mechanism in the machine head to move horizontally to the right to complete the door opening action, as shown in Figure 6 As shown; at this time, the electric telescopic door as a whole is still within the range of the passage ...

Abstract

The invention relates to an omni-directional traction electric door which comprises a door body and a machine head arranged at one end of the door body, the machine head comprises a machine head shelland an omni-directional traction mechanism arranged in the machine head shell, and the omni-directional traction mechanism comprises a bottom plate assembly and a Mecanum wheel assembly. The model selection of the door body comprises an electric telescopic door body, an electric translation telescopic door body or an electric folding door body. The electric door is provided with the omni-directional traction machine head designed according to the Mecanum wheel principle, and the machine head can be driven by a set program to complete movement in all directions; after being opened, the electric telescopic door and the electric translation telescopic door can swing to the position perpendicular to the telescopic direction by 90 degrees, and the problem that the channel width is still occupied after the door is opened is effectively solved; and the omni-directional traction machine head solves the problem that when an electric folding door is opened, a lateral thrust is needed to removea dead point.

Description

technical field [0001] The invention belongs to the technical field of electric door equipment, and in particular relates to an omnidirectional traction electric door. Background technique [0002] Electric doors are also known as "electric telescopic doors" or "electric folding doors". [0003] The electric doors on the market mainly include electric telescopic doors, electric translation telescopic doors and electric folding doors, etc., and their walking modes all move in a straight line. Among them, the electric telescopic door is the most common. It fixes the tail of the door body at one end of the passage, and the machine head drives the door body to expand and contract, so as to achieve the effect of opening and closing the door; since the electric telescopic door is folded and moved in a straight line along the direction of the passage, it shrinks to the shortest state. The bottom will still occupy part of the channel width. The feature of the electric translation ...
