Embodiment 1

[0028] figure 1 is an exploded view of an automatic driving device according to an embodiment of the present application. The automatic driving device is composed of a support frame 7, a transmission screw mandrel 11, a servo motor 12, a nut 10, a support slide bar 2 and a driving arm device 4. Wherein, the driving screw 11 is arranged inside the support frame 7 and fixedly connected with the support frame 7 . The servo motor 12 is mounted on one end of the driving screw 11 for driving the driving screw 11 to rotate. At least one nut 10 is sleeved on the driving screw rod 11 . The support slide bar 2 is arranged inside the support frame 7 and is fixedly connected with the support frame 7 . At least one driving arm device 4 is set on the supporting slide bar 2 and connected with the nut 10 and the door, and the nut 10 drives the driving arm device 4 to move left and right under the rotation of the driving screw 11. linear motion to cause the door to open and close. Prefera...

Embodiment 2

[0043] This embodiment is a new design added on the basis of embodiment 1, as figure 1 As shown, a logic controller 6 is also included, and the logic controller 6 is electrically connected to the servo motor 12 for controlling the servo motor 12 . The logic controller 6 controls the driving force and speed of the driving screw 11, receives external signals and processes and stores fault information.

[0044] On the other hand, the logic controller 6 can be installed on the support frame 7 in various ways, for example:

[0045] Mode 1, the logic controller 6 can be installed on the support frame 7 through bolts (not marked in the figure), which is convenient for disassembly and assembly, and is convenient for replacement and maintenance;

[0046] Mode 2, the logic controller 6 can be installed on the support frame 7 by welding, and the installation is firm and not easy to loosen.

Embodiment 3

[0048] This embodiment is a new design added on the basis of embodiment 1, as figure 1 As shown, it also includes a manual operation device 8 fixed to the support frame 7 , and the manual operation device 8 is electrically connected to the logic controller 6 . Described manual operation device 8 comprises sheet metal (not marked in the figure), is equipped with manual button (not marked in the figure) in described metal sheet, and described manual case comprises open key (not marked in the figure) and close key (not marked in the figure). not marked). The function of the manual operation device 8 is to use when the control of the logic controller 6 fails or when the door switch is manually operated during maintenance and testing.

Abstract

The invention relates to the technical field of power devices, in particular to an automatic driving device used between a door frame and a door of a bus. The automatic driving device comprises a support frame, a transmission screw rod arranged inside the support frame and fixedly connected with the support frame, a servo motor mounted at one end of the transmission screw rod and used for drivingthe transmission screw rod to rotate, at least one nut installed on the transmission screw rod in a sleeving manner, a support slide rod arranged inside the support frame and fixedly connected with the support frame, and at least one drive arm device arranged on the support slide rod in a sleeving manner and connected with the nut and the door, and the nut drives the drive arm device to do left-right linear motion under rotation of the transmission screw rod so that the door can be opened and closed. The servo motor is arranged at one end of the transmission screw rod and is used for controlling the smooth transmission of the transmission screw rod, so that the opening and closing speed of the door is stable, and the noise is small.

Description

technical field [0001] The present application relates to the technical field of power devices, in particular to an automatic driving device. Background technique [0002] At present, the doors of ordinary buses generally use pneumatic door opening and closing devices. Although the cost is low, it has many shortcomings. The more prominent shortcomings are: the transmission is not stable enough, resulting in sudden changes in the opening and closing speed, and some devices are exposed to aesthetics Poor and noisy. Contents of the invention [0003] (1) Technical problems to be solved: [0004] The purpose of the present invention is to propose an automatic driving device to solve the problem of insufficient smooth transmission. [0005] (2) Technical solution: [0006] In order to solve the above-mentioned technical problems, the application provides an automatic drive device used between the door frame and the door of the bus, which includes: a support frame; a transmis...
