[0001] This utility model relates to the field of elevator door operator technology, and more specifically, to a passenger elevator door operator. Background Technology

[0002] In modern high-rise buildings and various public places, passenger elevators are an important tool for vertical transportation. Their safety, reliability and operating efficiency are of paramount importance. The elevator door operator system, as a key component of the elevator, is responsible for controlling the opening and closing of the elevator doors, which is directly related to the personal safety of passengers and the normal operation of the elevator.

[0003] In traditional elevator door operator designs, door closure typically relies on simple mechanical contact or magnetic locks, which are susceptible to vibration or aging, leading to lock failure. This poses a safety hazard, as doors may open unexpectedly in the event of unforeseen circumstances (such as elevator malfunctions or external impacts). Therefore, we have proposed an improved passenger elevator door operator. Utility Model Content

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0024] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] For an example, please refer to... Figures 1-4 A passenger elevator door operator includes a support frame 1, on which a drive component is mounted. The drive component is connected to two door connecting plates 2. One door connecting plate 2 is equipped with a first hook 3, and the other door connecting plate 2 is equipped with a lifting component. The lifting component is connected to a first connecting plate 401, and one end of the first connecting plate 401 is fixedly connected to a second hook 402 that engages with the first hook 3. The engagement of the first hook 3 and the second hook 402 can limit the two door connecting plates 2, achieving a secure lock of the door in the closed state. This effectively reduces the accidental opening of the door during elevator operation or when subjected to external forces, thus improving safety.

[0027] The first hook 3 and the second hook 402 cooperate to limit the movement of the two ladder door connecting plates 2.

[0028] Furthermore, the lifting component includes an electric telescopic rod 4 installed on another ladder door connecting plate 2. The bottom end of the electric telescopic rod 4 is connected to the top of the first connecting plate 401. The electric telescopic rod 4 can drive the second hook 402 to rise and fall through the first connecting plate 401. When the second hook 402 descends, it can separate from the first hook 3, so as not to affect the movement of the ladder door connecting plate 2 when it is opened. When the second hook 402 is on, it can stop and limit each other with the first hook 3, so that the ladder door connecting plate 2 is locked after it is closed.

[0029] Furthermore, a third connecting frame 404 is installed on the top of the first connecting plate 401. The third connecting frame 404 is connected to a slide block 406. The slide block 406 is slidably connected to a slide rail 405, and the slide rail 405 is installed on another ladder door connecting plate 2. The slide rail 405, the slide block 406 and the third connecting frame 404 cooperate with each other to limit the first connecting plate 401, so as to improve the stability of the lifting and lowering of the first connecting plate 401.

[0030] Furthermore, the driving component includes two wheel frames 503 mounted on the support frame 1. Each wheel frame 503 is connected to a drive wheel 5 via a rotating shaft. A drive belt 502 is connected between the two drive wheels 5. A first connecting frame 201 is connected between the two ends of the drive belt 502. The first connecting frame 201 is connected to one of the ladder door connecting plates 2. A second connecting frame 202 is also connected to the drive belt 502. The second connecting frame 202 is connected to the other ladder door connecting plate 2. The drive belt 502 can drive the first connecting frame 201 and the second connecting frame 202 to move closer or further away from each other, thereby causing the two ladder door connecting plates 2 to move closer or further away from each other.

[0031] Furthermore, a motor 501 is mounted on one of the wheel frames 503. The output shaft of the motor 501 is connected to one of the rotating shafts. The motor 501 can drive the transmission wheel 5 and the transmission belt 502 to rotate.

[0032] Furthermore, a limiting component is installed on the support frame 1, which serves as a limiting buffer for the first connecting frame 201.

[0033] Furthermore, the limiting component includes a mounting bracket 7 installed on the support frame 1. A limiting buffer pad 701 is installed on the mounting bracket 7, and the position of the limiting buffer pad 701 corresponds to the position of the first connecting frame 201. When the limiting buffer pad 701 contacts the first connecting frame 201, it can play a limiting and buffering role.

[0034] Furthermore, a support member is provided between the support frame 1 and the two ladder door connecting plates 2; the support member includes a limiting guide rail 6 provided on the support frame 1, and a number of first limiting wheels 601 are slidably connected to the top of the limiting guide rail 6. The first limiting wheels 601 are connected to the ladder door connecting plates 2, and the first limiting wheels 601 and the limiting guide rail 6 cooperate with each other to provide support and limit the ladder door connecting plates 2.

[0035] Furthermore, the bottom of the limiting guide rail 6 is slidably connected with several second limiting wheels 602. The second limiting wheels 602 are connected to the ladder door connecting plate 2. The second limiting wheels 602 and the limiting guide rail 6 cooperate with each other to limit the ladder door connecting plate 2 and improve the stability of the ladder door connecting plate 2 when it moves.
