[0025] Refer to the attached Figure 1 As shown, the upward folding electric door of this embodiment includes a door frame 1, a folding door panel 2 and a power mechanism 3.

[0026] Refer to the attached Figure 2 and 3 As shown, three guide rails 11, 12, 13 are respectively arranged on the door legs on both sides of the door frame 1 in this embodiment. The lower parts of the three guide rails 11, 12, 13 are arranged in parallel, and the upper parts thereof are all curved outwardly in an arc shape. The bending starting points of the upper curved sections of the three guide rails 11, 12, 13 are different, such as the bending starting point a of the inner guide rail 11 is the highest, the bending starting point b of the middle guide rail 12 is lower than the bending starting point a, and the bending starting point c of the outer guide rail 13 is lower than the bending starting point b; and the outward bending angle α of the inner guide rail 11 is smaller than the outward bending angles β and γ of the middle guide rail 12 and the outer guide rail 13. In this embodiment, the outward bending angles β and γ of the middle guide rail 12 and the outer guide rail 13 are equal. Of course, the outward bending angles β and γ of the middle guide rail 12 and the outer guide rail 13 may also be unequal, but both are greater than the outward bending angle α of the inner guide rail 11.

[0027] In this embodiment, the folding door panel 2 is hingedly connected by five door panels 21, 22, 23, 24, and 25. The middle part of the first door panel 21 at the top is symmetrically provided with guide wheels 211 on both sides, and the guide wheels 211 are arranged in the innermost guide rail 11. The connection between the second door panel 22 and the third door panel 23 is provided with a first guide wheel 221, and the first guide wheel 221 is arranged in the middle guide rail 12. The connection between the fourth door panel 24 and the fifth door panel 25 is provided with a second guide wheel 241, and the second guide wheel 241 is arranged in the outermost guide rail 13. Of course, the folding door panel 2 can also include 3, 7 or other odd-numbered door panels. For example, when there are three door panels, only the guide wheel 211 and the first guide wheel 221 are included, and they only match the inner guide rail 11 and the middle guide rail 12. If there are 7 door panels, a third guide wheel is also provided at the connection between the sixth door panel and the seventh door panel, and the third guide wheel is arranged in the guide rail further outward of the outer guide rail 13, and they are arranged in sequence.

[0028] The power mechanism 3 in this embodiment includes a transmission shaft 31, a transmission motor 32 and a transmission chain 33. The transmission shaft 31 is arranged above the door frame 1, that is, at the door lintel.

The transmission motor 32 is arranged on one side of the transmission shaft 31, and drives the transmission shaft 31 to rotate. The transmission shaft 31 then drives the transmission chain 33 to drive, and the transmission chain 33 provides the folding door panel 2 with power to slide up and down. That is, the folding door panel 2 is driven by the transmission chain 33, and through the guidance of the guide wheel 211 and different guide wheels by different guide rails, the door sheet of the folding door panel 2 is guided to fold and unfold reciprocally, so as to realize the opening and closing of the folding door panel 2. As shown in the attached figure Figure 2 The folding door panel 2 is shown in a closed state. Figure 3 The folding door panel 2 is shown in an open state.

[0029] In order to better promote the folding of the door sheet, when the folding door panel 2 is in the closed state, the guide wheel 211 is arranged at the bending starting point a of the innermost guide rail 11, so that when the folding door panel 2 is subjected to an upward lifting force, the first door sheet 21 is guided by the guide wheel 211 and the inner guide rail 11, so that the upper end of the first door sheet 21 is inclined in the bending direction of the inner guide rail 11 until the first door sheet 21 is arranged horizontally in the door lintel space. Since the second door sheet 22 is hinged to the first door sheet 21, the second door sheet 22 also moves upward, and then when the first guide wheel 221 enters the curved section of the middle guide rail 12, the first guide wheel 221 guides the second door sheet 22 and the third door sheet 23 to be folded in half and enter the door lintel space. Due to the hinge connection between the fourth door panel 24 and the third door panel 23, the fourth door panel 24 also moves upward, and then when the second guide wheel 241 enters the curved section of the outer guide rail 13, the second guide wheel 241 guides the fourth door panel 24 and the fifth door panel 25 to be folded and enter the door lintel space. In addition, the bottom end of the fifth door panel 25 can continue to lift the fifth door panel 25 to a parallel horizontal state due to the fixed connection with the transmission chain 33, so that all the door panels are in a folded and stowed state.

[0030] Of course, the transmission chain 33 can also be connected to the connection between the odd-numbered door panels and the even-numbered door panels from top to bottom of the folding door panel 2. For example, it can be connected to the connection between the first door panel 21 and the second door panel 22, or / and connected to the connection between the third door panel 23 and the fourth door panel 24, which can better assist the transmission chain 33 in driving the folding door panel 2 to move upward, better disperse the force at different parts of the folding door panel, and improve the service life of the folding door panel 2.

[0031] The upper portion of the door frame 1 of this embodiment is provided with a storage space S for the folding door panel 2 to be folded and stowed laterally, and the lower portion of the storage space S is arranged as a slope structure matching the bending angle of the outermost guide rail 13, providing space for the door panel to be folded when stowed.

[0032] In the folding door panel 2 described in this embodiment, a hidden hinge is arranged between adjacent door panels, so that the entire door panel is flatter and more beautiful. Of course, hinges can also be arranged between adjacent door panels, as long as the folding direction of the door panels can be met. The hidden hinge described in this embodiment can be any hidden hinge of door panels in the art, ensuring that the inside and outside of the door panel are flat and beautiful.

[0033] In addition, in this embodiment, both ends of the transmission shaft 31 are provided with counterweight torsion springs 34 to ensure the power balance of the transmission motor 32 lifting the folding door panel 2.

[0034] The operating principle of the upward folding electric door of the utility model is as follows: when the electric door is opened, the transmission motor 32 lifts the transmission chain 33, giving an upward force to the bottom door leaf. First, the guide wheel of the first door leaf 21 is guided by the inner guide rail 11 to start to flip outward, and the other door leaves continue to move upward. When the lower guide wheels enter the curved sections of the corresponding guide rails in turn, the door leaves connected thereto are also guided to complete the reciprocating folding, until all the door leaves are folded. Figure 3 As shown, the folding and opening of the folding door panel 2 is completed. When the door needs to be closed, the transmission motor 32 is reversed, and the door sheet moves down along the guide rail in sequence under the action of its own weight until the door is closed in place.

[0035] The utility model upward folding electric door can be used for large space partition doors and garage doors, and truly solves the problem of large space occupation of sliding doors and pivot doors. By improving the guide rails on the door legs, the door panels can be flexibly and conveniently guided to fold, and the folding, stowing and unfolding of the folding door panels can be realized simply and easily. The outer ends of the folding door panels can also be supported by the setting of multiple guide rails, ensuring that the support and fixation of the door panels after folding are stable and reliable. The entire door panel of the upward folding electric door is flat, with a large design space, which is conducive to the aesthetic design of the door panel, making it more ornamental and market competitive.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Those skilled in the art may make some simple modifications, equivalent changes or modifications using the technical contents disclosed above, which are all within the protection scope of the present invention.
