Detailed Description
The present invention will be further described with reference to the following embodiments and the accompanying drawings.
It is to be understood that the appended drawings are not to scale, but are merely drawn with appropriate simplifications to illustrate various features of the basic principles of the invention. Specific design features of the invention disclosed herein, including, for example, specific dimensions, orientations, locations, and configurations, will be determined in part by the particular intended application and environment of use.
In the several figures of the drawings, identical or equivalent components (elements) are referenced with the same reference numerals.
Fig. 1 shows an elevator in a door-open state with a first embodiment of a device for detecting the door-closed in place state of the elevator door according to the invention. The elevator door shown in fig. 1 is a center opening door, which comprises a door frame 1, a first door panel 2 and a second door panel 3. A first door panel 2 and a second door panel 3 are mounted on the door frame 1 horizontally movable relative to each other for opening and closing the elevator car. An induction assembly 4 is fixed on the gantry 1. The sensing assembly 4 is located between the first door panel 2 and the second door panel 3, and is used for detecting the door closing in-place state of the center opening door. A first bracket 5 is provided on the first door panel 2. The first sensing piece 7 is disposed on a side of the first bracket 5 facing the sensing assembly 4. A second bracket 6 is provided on the second door panel 3. A second sensing block 8 is arranged on the side of the second bracket 6 facing the sensing assembly 4. The first bracket 5 and the second bracket 6 may each be configured in an L-shape. The first bracket 5 and the second bracket 6 may have other shapes suitable for mounting and fixing.
Fig. 2 shows an elevator in a door closed in place state with a device for detecting the door closed in place state of the elevator door according to the invention. In the state of fig. 2, the first sensing piece 7 is in its closest position to the sensing assembly 4. At this time, the sensing assembly 4 detects the first sensing piece 7 and determines that the first door panel 2 is in its door closed position. In the state of fig. 2, the second sensing piece 8 is also in its closest position to the sensing assembly 4. At this time, the sensing assembly 4 detects the second sensing piece 8 and determines that the second door panel 3 is in its door closed position. Only when the sensing assembly 4 confirms that the first door panel 2 and the second door panel 3 are both in the respective door closing in-place state, the sensing assembly 4 sends a signal to the elevator control system to inform that the elevator is in the door closing in-place state.
Fig. 3 shows an and logic circuit a of the sensing element 4 in the first embodiment. The sensing element 4 generates and inputs a first input signal B into the and logic circuit a when it determines that the first door panel 2 is in its door closed position, and the sensing element 4 generates and inputs a second input signal C into the and logic circuit a when it determines that the second door panel 3 is in its door closed position. When the first signal B and the second signal C are both input into the AND logic circuit A, the AND logic circuit A outputs a signal D which indicates that the door of the elevator is closed in place to the elevator control system. If only one input signal is received by the AND logic circuit, the AND logic circuit does not output a signal if the elevator door is not closed in place.
Fig. 4 shows a second embodiment of the device for detecting the door closing in place state of an elevator door according to the present invention. In the embodiment of fig. 4, a photoelectric switch 9 is fixed to the gantry 1. The photoelectric switch 9 is arranged between the first door panel 2 and the second door panel 3 and is used for detecting the door closing in-place state of the center opening door. The photoelectric switch 9 has a light emitting element 12 and a light receiving element 13 arranged vertically, and a light beam 14 generated downward from the light emitting element 12 can be received by the light receiving element 13. A first bracket 5 is provided on the first door panel 2. The first light shielding plate 10 is disposed on a side of the first support 5 facing the photoelectric switch 4. A second bracket 6 is provided on the second door panel 3. The second light shielding plate 11 is disposed on a side of the second support 6 facing the photoelectric switch 4. When the elevator door is gradually closed, the first light shielding plate 10 and the second light shielding plate 11 move toward each other and protrude between the light emitting element 12 and the light receiving element 13 from both sides of the photoelectric switch 9, respectively, thereby gradually shielding the light beam 14. In the state of fig. 4, i.e., when the elevator door is completely closed to the right, the first light shielding plate 10 shields half of the light beam 14 emitted from the light emitting element 12, and the second light shielding plate shields the other half of the light beam 14 emitted from the light emitting element 12. At this time, the photoelectric switch 9 outputs a door closing in-place signal to the elevator control system.
The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. The foregoing description is not intended to be exhaustive or to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and its practical application to enable others skilled in the art to make and use various exemplary embodiments of the invention and various alternatives and modifications thereof. It is intended that the scope of the invention be defined by the following claims and their equivalents.
