Description

Technical Field

[0001] The utility model relates to the technical field of protection detection equipment, in particular to a door protection device and an elevator. Background Art

[0002] With the continuous progress of technology, induction doors have been widely used in modern buildings. Especially in elevators, automatic doors and other occasions, their safety and convenience have become key factors in design. The development of induction door area detection technology aims to improve the reliability of the system and the safety of passengers. At present, the induction door area detection technology is mainly divided into two schemes: "contact type" and "non-contact type".

[0003] The "contact type" induction door detection scheme is mainly composed of a pair of mechanical touch plates, micro switches and linkage devices. When a passenger or other object touches the mechanical touch plate, the linked micro switch is pressed, and the elevator door control system receives the "obstruction" signal, so as to keep the door open or immediately stop closing and then open the door. However, this detection method requires a certain impact force and a suitable impact angle to effectively trigger the micro switch. Otherwise, it may continue to close the door, posing a safety risk to passengers.

[0004] The "non-contact type" induction door detection scheme is composed of multiple groups of infrared light pairs, forming an invisible safety wall. When a passenger or other object blocks the infrared light, the elevator door control system receives the "obstruction" signal, so as to keep the door open or immediately stop closing and then open the door. This detection method has high safety and convenience, because passengers do not need to directly touch the touch plate, and only need to approach the door to trigger the switch. However, due to the probability of infrared light failure or interference by other light sources, it may lead to missed detection and continue to close the door, also posing a safety risk to passengers.

[0022] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the specific embodiments cited shall not be construed as limiting the present utility model.

[0023] Embodiment 1

[0024] See Figure 1 As shown, this embodiment provides a door body protection device, which includes: a first detection mechanism 100, the first detection mechanism 100 includes a relatively arranged transmitting component 110 and a receiving component 120, the transmitting component 110 includes a first circuit board 112 and a transmitting diode 114 which are connected to each other, and the receiving component 120 includes a second circuit board 122 and a receiving diode 124 which are connected to each other; a second detection mechanism 200, the second detection mechanism 200 includes an elastic body 210 and at least two pressing members 220, the elastic body 210 is connected to the edge of the door body to be protected, at least two of the pressing members 220 are arranged on the side of the elastic body 210 away from the door body, and are arranged at intervals along the moving direction of the door body, and any one of the pressing members 220 includes a conductive layer 222 and a wire 221 which are connected to each other; a central control mechanism 300, the first circuit board 112, the second circuit board 122 and the wire 221 are respectively connected to the central control mechanism 300.

[0025] The door body protection device in this embodiment uses the first detection mechanism 100 to perform non-contact detection on whether there is an obstacle on the moving path of the door body, and at the same time uses the second detection mechanism 200 to perform contact detection, thereby realizing the dual protection effect on the door body. In the actual use process, even if there is light source interference or ineffective collision, it can still have an efficient protection effect, thereby greatly reducing the risk of accidental closing of the door body. Compared with conventional door bodies and related structures, this device has significant advantages such as fast response speed, dual protection, high controllability, convenient assembly and connection, and wide application range, and has broad application prospects in this industry.

[0026] The door protection device in this embodiment is applied to the elevator door. Among them, the first detection mechanism 100 detects whether there is an obstruction at the door through a non-contact detection method. Specifically, when there is no obstruction at the door, the receiving component 120 can receive the detection light emitted by the transmitting component 110; when there is an obstruction at the door, it will block the transmission path of the detection light, so that the receiving component 120 cannot receive the transmitted light, thereby achieving the purpose of detecting whether the moving path of the door is unobstructed. Correspondingly, when there is an obstacle, the door will cause the electrical connection between the extrusion members 220 due to the deformation of the elastic body 210 during the movement, and thus feedback the signal of the existence of the obstacle in the form of an electrical signal, thereby realizing the detection process. Based on the above settings, when there is interfering light or other factors that cause the first detection mechanism 100 to fail at the door, the second detection mechanism 200 can achieve detection through physical contact extrusion. On the contrary, when the second detection mechanism 200 fails, the first detection mechanism 100 can also achieve the detection purpose.

[0027] See Figure 1 As shown, this embodiment includes two relatively arranged elevator doors. The transmitting component 110 and the receiving component 120 are respectively connected to the edges of the opposite sides of the two elevator doors and are located at the same horizontal height. Among them, the transmitting component 110 includes a first lens 113, and the first lens 113 is spaced from the emitting end of the emitting diode 114; the receiving component 120 includes a second lens 123, and the second lens 123 is spaced from the receiving end of the receiving diode 124. Among them, the first lens 113 and the second lens 123 are used for directional convergence transmission of light to ensure that the light can be accurately transmitted from the transmitting component 110 to the receiving component 120.

[0028] Furthermore, the transmitting component 110 includes a first mounting bracket 111. The first mounting bracket 111 is internally provided with a first accommodation groove and a second accommodation groove. The first circuit board 112 and the first lens 113 are both arranged in the first accommodation groove, and the second detection mechanism 200 is connected to the second accommodation groove. In this embodiment, the first mounting bracket 111 is used to provide a mounting platform for the transmitting component 110 and the second detection mechanism 200. The first accommodation groove and the second accommodation groove are arranged at intervals in the height direction of the first mounting bracket 111. Further, the first accommodation groove is provided with a first fixing portion connected to the first lens 113, and the edge of the first lens 113 is inserted and connected into the first fixing portion. Correspondingly, the second accommodation cavity is also provided with a second fixing portion connected to the elastic body 210.

[0029] Similarly, the receiving component 120 includes a second mounting bracket 121 for providing a mounting platform for the receiving component 120. A third accommodation groove is provided inside the second mounting bracket 121, and the second circuit board 122 and the second lens 123 are both disposed in the third accommodation groove. Further, the structure of the third accommodation groove is the same as that of the first accommodation groove, and a third fixing portion connected to the second lens 123 is also provided thereon.

[0030] Further, to facilitate the connection of the wire 221 to achieve electrical signal transmission, wire grooves for the wire 221 are provided inside both the first mounting bracket 111 and the second mounting bracket 121 in this embodiment. The first circuit board 112 and the second circuit board 122 are both connected to the central control mechanism 300 through the wire 221.

[0031] See Figure 1 As shown, the elastic main body 210 in this embodiment includes a squeezing portion 212 and a connecting portion 211. The connecting portion 211 is connected to the edge of the door body to be protected, and at least two of the squeezing members 220 are arranged at intervals inside the squeezing portion 212. Further, to avoid electric current misinjury, the elastic main body 210 in this embodiment is filled with insulating filler. Specifically, the elastic main body 210 in this embodiment is preferably a rubber component. When the door body comes into contact with an obstacle, the elastic main body 210 can cause electrical connection between the squeezing members 220 through its deformation. Specifically, two squeezing members 220 are provided in this embodiment, and the two squeezing members 220 are arranged at intervals along the moving direction of the door body inside the squeezing portion 212. In the normal state without an obstacle, there is an interval between the two squeezing members 220 and no electrical signal transmission occurs between them. When there is an obstacle, the squeezing between the door body and the obstacle causes the elastic main body 210 to deform, and then the two squeezing members 220 come into contact, thereby realizing the detection process after electrical conduction. Specifically, the wire 221 is arranged at the center of the corresponding wire 221 layer in this embodiment to improve its contact sensitivity.

[0032] See Figure 2As shown in the figure, the central control mechanism 300 in this embodiment includes a signal conversion module 310 and a control module 320 that are connected to each other. The first circuit board 112, the second circuit board 122, and the wire 221 are respectively connected to the signal conversion module 310. Among them, the signal conversion module 310 collects the electrical signals transmitted by the first detection mechanism 100 and the second detection mechanism 200 and transmits them to the central control mechanism 300. Further, the central control mechanism 300 further includes a display component, the display component is connected to the signal conversion module 310, the display component includes a touch lamp group 330, the touch lamp group 330 is connected to the signal conversion module 310, and the touch lamp group 330 is arranged inside the elastic body 210. Further, the touch lamp group 330 includes at least two lamp bodies. Based on this, the central control mechanism 300 can drive the corresponding lamp bodies to give feedback on the detection results to remind personnel to pay attention. The two lamp bodies in this embodiment can emit different colors of light. In other embodiments, the lamp body can also give prompts through the light intensity and the number of lights emitted. Similarly, it can also be provided with other warning structures such as a buzzer and a display screen as the display component, and the present utility model does not make specific restrictions on this.

[0033] In other embodiments, a shielding lamp group (not shown in the figure) can also be provided. The shielding lamp group is connected to the signal conversion module 310, and the shielding lamp group is connected to the transmitting component 110 and / or the receiving component 120.

[0034] Embodiment 2

[0035] This embodiment provides an elevator, which includes the door protection device described in Embodiment 1.

[0036] In summary, for the door protection device and elevator of the present utility model, the first detection mechanism 100 performs non-contact detection on whether there are obstacles on the moving path of the door, and at the same time, the second detection mechanism 200 performs detection when contacting, thereby achieving a dual-effect of door protection. In the actual use process, even if there is light source interference or ineffective collision, it can still have an efficient protection effect, thereby greatly reducing the risk of accidental door closing. Compared with conventional doors and related structures, this device has significant advantages such as fast response speed, dual protection, high controllability, convenient assembly and connection, and wide application range, and has a broad application prospect in this industry.

[0037] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
