Abstract
Description
Technical Field
[0001] This utility model relates to the field of special vehicle technology, and in particular to an automatic upward-opening door structure. Background Technology
[0002] Existing special vehicle cabins all have top doors, which are basically swing-open or flip-up types. To facilitate opening, most top doors are flip-up structures. However, most existing flip-up top doors are manually operated. Manually operated top doors have the following shortcomings in actual use:
[0003] 1. The manually operated top door requires manual force to push it open and close, which is time-consuming and laborious to operate;
[0004] 2. Existing top-hinged doors are not only structurally complex, but also very cumbersome to install and disassemble, making them inconvenient for daily inspection and maintenance.
[0005] 3. When the top-hinged door is opened, it is prone to shaking and collision due to the bumps and jolts of the vehicle, posing a certain safety hazard.
[0006] Therefore, there is an urgent need for an automatic upward-opening door structure that can overcome the above-mentioned shortcomings. Utility Model Content
[0007] In order to overcome the shortcomings of the prior art, this utility model discloses an automatic upward-opening door structure. This utility model can not only realize the automatic upward opening and closing of the door panel, but also effectively limit and fix the upward-opening door panel to avoid shaking and collision after the door panel is opened.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] An automatic upward-opening door structure includes a door panel installed inside a door frame and capable of being flipped upwards and opened. The lower part of the door frame is provided with a drive mechanism for automatically pushing the door panel upwards and opening. The drive mechanism includes an electric cylinder and a connecting rod. The electric cylinder is located at the lower part of the door frame and is vertically arranged. The upper end of the telescopic rod inside the electric cylinder is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the lower surface of the door panel.
[0010] Furthermore, a hinge seat is provided on the inner wall of one side of the door frame, and a hinge that is fixedly connected to the upper surface of the door panel is hinged to the hinge seat.
[0011] Furthermore, the connecting rod is an L-shaped rod consisting of a short arm and a long arm. The end of the short arm of the connecting rod is hinged to the end of the telescopic rod, and the end of the long arm of the connecting rod is hinged to the lower surface of the door panel.
[0012] Furthermore, a limiting mechanism for limiting and fixing the door panel after it is opened is provided between the short arm end of the connecting rod and the telescopic rod end. The limiting mechanism includes a U-shaped connecting seat, a rotating ring, an adsorption component, and an adsorption plate. The upper end of the telescopic rod is provided with a U-shaped connecting seat, the short arm end is provided with a rotating ring that is hinged to the U-shaped connecting seat, one side of the telescopic rod body is provided with an adsorption component, and one side of the rotating ring is provided with an adsorption plate that rotates synchronously with the U-shaped connecting seat and adsorbs or separates from the adsorption component.
[0013] Furthermore, a mounting base is provided on one side of the end of the telescopic rod, and the adsorption component can be detachably installed in the mounting base.
[0014] Furthermore, a connecting seat is provided on the lower surface of the door panel, and the connecting rod is hinged to the door panel through the connecting seat.
[0015] Compared with the prior art, the beneficial effects of this utility model are: through the cooperation of electric cylinder and connecting rod, the automatic upward opening and closing of the door panel can be realized;
[0016] By setting up a connecting rod with an L-shaped rod structure, as well as a hinge seat and hinge, the door panel can be opened and closed 180°.
[0017] By setting a limiting mechanism, when the door panel is flipped open, the adsorption component can effectively adsorb onto the adsorption plate, thereby limiting and fixing the hinged part of the connecting rod and the telescopic rod, thus effectively preventing the door panel from shaking after it is opened.
[0018] This invention not only enables the automatic upward opening and closing of door panels, but also effectively limits and fixes the opened door panels to prevent shaking and collisions. This invention has a simple structure and is easy to operate, which not only facilitates daily inspection and maintenance, but also greatly saves costs. Attached Figure Description

[0023] The technical solution of this utility model will be described below with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.
[0024] Please refer to the instruction manual appendix. Figure 1-3 This utility model provides a technical solution:
[0025] Example 1: An automatic upward-opening door structure includes a door panel 1 installed inside a door frame 4 and capable of being flipped upwards and opened. The lower part of the door frame 4 is provided with a drive mechanism for automatically pushing the door panel 1 to flip upwards and open. The drive mechanism includes an electric cylinder 8 and a connecting rod 3. The electric cylinder 8 is located at the lower part of the door frame 4 and is vertically arranged. The upper end of the telescopic rod 7 inside the electric cylinder 8 is hinged to one end of the connecting rod 3, and the other end of the connecting rod 3 is hinged to the lower surface of the door panel 1. In order to facilitate the hinge between the connecting rod 3 and the door panel 1, a connecting seat 2 is provided on the lower surface of the door panel 1, and the connecting rod 3 is hinged to the door panel 1 through the connecting seat 2.
[0026] When opening the door panel 1, simply raise the telescopic rod 7 inside the electric cylinder 8, thereby driving the connecting rod 3 to move upward. As the connecting rod 3 moves, the door panel 1 can be flipped upward and lifted, thus realizing the automatic upward opening of the door panel 1. When closing the door panel 1, simply lower the telescopic rod 7 inside the electric cylinder 8, thereby using the downward movement of the connecting rod 3 to drive the door panel 1 to snap back into the door frame 4.
[0027] In embodiment two, in order to fully expose the door frame 4 after the door panel 1 is opened upwards, a hinge seat 6 is provided on the inner wall of one side of the door frame 4. A hinge 5 is hinged to the hinge seat 6 and fixedly connected to the upper surface of the door panel 1. The connecting rod 3 is an L-shaped rod composed of a short arm 11 and a long arm 10. The end of the short arm 11 of the connecting rod 3 is hinged to the end of the telescopic rod 7, and the end of the long arm 10 of the connecting rod 3 is hinged to the lower surface of the door panel 1. By using the connecting rod 3 with its L-shaped rod structure and the door panel 1 connected by the hinge seat 6 and the hinge 5, the door panel 1 can be opened upwards by 180°.
[0028] In Example 3, since both ends of the connecting rod 3 are hinged, when the door panel 1 is opened, it is very easy for the door panel 1 to shake and collide, which poses a certain safety hazard. In order to prevent the door panel 1 from shaking after it is opened, a limiting mechanism 9 is provided between the end of the short arm 11 of the connecting rod 3 and the end of the telescopic rod 7 to limit and fix the door panel 1 after it is opened. Specifically, the limiting mechanism 9 includes a U-shaped connecting seat 16, a rotating ring 12, an adsorption component 14 and an adsorption plate 13. The upper end of the telescopic rod 7 is provided with a U-shaped connecting seat 16, the end of the short arm 11 is provided with a rotating ring 12 that is hinged to the U-shaped connecting seat 16, one side of the end of the telescopic rod 7 is provided with a mounting seat 15, the adsorption component 14 is detachably installed in the mounting seat 15, and one side of the rotating ring 12 is provided with an adsorption plate 13 that rotates synchronously with the U-shaped connecting seat 16 and adsorbs or separates from the adsorption component 14.
[0029] The adsorption component 14 can be a suction cup, a magnet, or an electromagnet. The suction cup or magnet can adsorb or separate as the adsorption plate 13 rotates. If an electromagnet is used, the electromagnet is connected to the control switch circuit of the electric cylinder 8. That is, when the electric cylinder 8 presses the up switch, the electromagnet is energized, and when the electric cylinder 8 installs the down switch, the electromagnet is de-energized.
