[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it designate a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing embodiments of the present invention, cross-sectional views of device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0029] Example 1, with reference to Figure 1 and Figure 2 , provides a simple elevator earthquake detection sensor, including a container 100; the container 100 is a closed shell, and a wire harness port is provided on the container 100 for feeding the wire harness into the interior of the container 100.

[0030] The simple elevator earthquake sensor includes a support member 200 , which is fixed inside the container 100 . The main function of the support member 200 is to form a supporting position inside the container 100 .

[0031] The simple elevator earthquake detection sensor includes a bonding electrode 300, which is provided on a support member 200. When installed on an elevator, the bonding electrode 300 is connected to the control structure of the elevator.

[0032] The simple elevator detection earthquake sensor includes a bottom electrode 400 fixed in a container 100. When installed on an elevator, the bottom electrode 400 is connected to the control structure of the elevator.

[0033] The simple elevator earthquake detection sensor includes a conductive member 500, which is placed on a support member 200. The support member 200 can support the conductive member 500. When the support member 200 supports the conductive member 500, the conductive member 500 contacts the bottom electrode 400. Therefore, during normal operation, the support member 200 supports the conductive member 500, and the conductive member 500 connects the bottom electrode 400 and the bonding electrode 300. When the elevator stalls and descends rapidly, the container 100 drives the bonding electrode 300 and the bottom electrode 400 to move downward. At this moment, the conductive member 500 moves upward relative to the container 100, and the conductive member 500 disengages from the bottom electrode 400, thereby disconnecting the bonding electrode 300 and the bottom electrode 400. The control structure of the elevator receives a signal that the bonding electrode 300 and the bottom electrode 400 are disconnected, and thus takes remedial measures.

[0034] Specifically, the container 100 includes an upper insulating plate 101 and a lower insulating plate 102 ; the container 100 also includes a middle frame 103 , one end of the middle frame 103 is connected to the upper insulating plate 101 , and the other end of the middle frame 103 is connected to the lower insulating plate 102 .

[0035] In this embodiment, the upper insulating plate 101 and the lower insulating plate 102 are both circular structures, and the middle frame 103 is annular. The axial ends of the middle frame 103 are respectively connected to the upper insulating plate 101 and the lower insulating plate 102, so that the container 100 forms a relatively closed inner cavity.

[0036] Furthermore, the bottom electrode 400 is mounted on the lower insulating plate 102 , and the support member 200 is fixed on the lower insulating plate 102 . The support member 200 is a ring-shaped structure, and the bottom electrode 400 is located at the center of the support member 200 .

[0037] Because the support member 200 is annular, the support member 200 has an inner ring, which supports the conductive member 500 , and a portion of the conductive member 500 is connected to the bottom electrode 400 through the inner ring.

[0038] Example 2, reference Figure 3 This embodiment is different from the first embodiment in that it further includes an annular electrode 600, which is arranged on the radial inner wall of the middle frame 103, wherein the annular electrode 600 is also connected to the control structure of the elevator.

[0039] Under normal conditions, because the support member 200 limits the conductive member 500, the conductive member 500 is in a state of connecting the bottom electrode 400 and the bonding electrode 300. When an earthquake occurs, the elevator will shake left and right. At this time, the conductive member 500 will detach from the support member 200 and move toward the edge of the container 100. Finally, the conductive member 500 will contact the annular electrode 600 and the bonding electrode 300 at the same time, connecting the two. The control structure of the elevator receives the signal that the annular electrode 600 and the bonding electrode 300 are connected, and thus responds accordingly.

[0040] Specifically, the inner ring of the support member 200 forms an annular surface 201 , the upper surface of the support member 200 forms an upper plane 202 , and a connecting surface 203 is formed between the annular surface 201 and the upper plane 202 ; the bonding electrode 300 is bonded to the connecting surface 203 and the upper plane 202 .

[0041] Furthermore, the conductive member 500 is spherical, the connecting surface 203 is an arcuate surface, the outer spherical surface of the conductive member 500 fits the arcuate surface, and the distance between the upper plane 202 and the upper insulating plate 101 is greater than the diameter of the conductive member 500, thereby providing space for the conductive member 500 to move.

[0042] The rest of the structure is the same as that of Example 1.

[0043] Example 3. This embodiment is different from the above embodiments in that: an elevator includes the simple elevator earthquake detection sensor in the above embodiments, and also includes a car, and the simple elevator earthquake detection sensor is installed on the car; it also includes a control module, and the simple elevator earthquake detection sensor is connected to the control module.

[0044] The workflow of the simple elevator earthquake detection sensor in the entire elevator is as follows:

[0045] S1. The system starts monitoring to see whether the bonding electrode 300 and the bottom electrode 400 are normally connected, and whether the ring electrode 600 and the bonding electrode 300 are normally disconnected.

[0046] S2.1. The bonding electrode 300 is disconnected from the bottom electrode 400, and the annular electrode 600 is electrically connected to the bonding electrode 300, and the process proceeds to step S3.1.

[0047] S2.2. The bonding electrode 300 is disconnected from the bottom electrode 400, and the annular electrode 600 is electrically disconnected from the bonding electrode 300, and the process proceeds to step S3.2.

[0048] S2.3. The bonding electrode 300 is electrically connected to the bottom electrode 400, and the annular electrode 600 is electrically connected to the bonding electrode 300, and the process proceeds to step S3.3.

[0049] S2.4, the bonding electrode 300 is electrically connected to the bottom electrode 400, and the annular electrode 600 is electrically disconnected from the bonding electrode 300, and the process proceeds to step S3.4.

[0050] S3.1, determine the earthquake and go to S4.1

[0051] S3.2, delay and then determine whether the signal is restored. If the signal is restored, it is determined that the elevator has an overweight condition. If it is not restored, it is determined that the sensor is faulty or the control circuit is disconnected, and enter step S4.2.

[0052] S3.3: Determine if the sensor is faulty due to water ingress or if there is a fault in the elevator car control system, and proceed to step S4.2.

[0053] S3.4. Determine that the system is normal, continue monitoring, and return to S1.

[0054] S4.1. The elevator stops operating immediately, all car doors open, an audible and visual alarm sounds, and a message is sent to the backend.

[0055] S4.2. If the elevator is carrying passengers, it will stop operating after completing the task of carrying passengers, close the car, and send a related fault signal to the backend.

[0056] The rest of the structure is the same as that of Example 2.
