[0032] like Figure 1-5 As shown, this application relates to a wireless intercom device for an elevator 3. The wireless intercom device for an elevator 3 includes: a housing 1, a circuit board 2 disposed inside the housing 1 and fixed to the car wall of the elevator 3, a controller 4, a wireless communication device 5 and a voice communication device 6 disposed on the circuit board 2, and an antenna 9 connected to the wireless communication device 5. The controller 4 is electrically connected to the wireless communication device 5 and the voice communication device 6, and the antenna 9 extends through the car wall to the outside of the car.

[0033] Specifically, the housing 1 serves to support the various components. In this embodiment, a fixing seat 19 is provided on the connecting side of the housing 1, and the fixing seat 19 is connected to the car wall by bolts; this allows the wireless intercom device of the elevator 3 to be fixed to the car wall of the elevator 3. The circuit board 2 serves to house the various components. In this embodiment, the circuit board 2 is equipped with at least a controller 4, a wireless communication device 5, and a voice communication device 6. The controller 4 provides central control, the wireless communication device 5 can receive or send information wirelessly, and the voice communication device 6 can record or play voice information. Preferably, the voice communication device 6 can also decode and amplify the recorded or played voice to ensure clear playback. Preferably, the wireless communication device 5 is a 4G communication device, enabling two-way communication, receiving voice signals sent from the car end, and sending voice signals from the community monitoring center to the car end. It has a certain signal enhancement function. In this embodiment, an antenna 9 is connected to the wireless communication device 5, and the antenna 9 is located outside the car. This effectively prevents the car from blocking signal transmission, avoiding signal shielding, thereby effectively enhancing the signal and improving call quality.

[0034] As can be seen from the above description, this application achieves the following technical effects:

[0035] In this embodiment, a circuit board 2 is provided inside a housing 1 and fixed to the car wall of an elevator 3. The circuit board 2 is equipped with a controller 4, a wireless communication device 5, and a voice communication device 6. An antenna 9 is connected to the wireless communication device 5. The controller 4 is electrically connected to the wireless communication device 5 and the voice communication device 6. The antenna 9 extends through the car wall to the outside of the car. This effectively enhances the signal and improves the call quality, thereby solving the technical problem of poor call quality caused by the shielding function of the elevator car.

[0036] Preferably, the antenna 9 is disposed at the top of the car. Distributing the antenna 9 outside the car and at the top effectively enhances its signal transmission and reception capabilities, thereby preventing signal shielding by the elevator car and improving signal strength, thus improving call quality. Furthermore, the wireless communication device 5 is connected to the antenna 9 at the top via a transmitting / receiving line 8, which is disposed in a wiring groove 10 in the car wall and communicates with the outside. The wiring groove 10 in the car wall effectively organizes the transmitting / receiving line 8 connecting the antenna 9 and the wireless communication device 5. Even further, the wiring groove 10 is arranged on the inner side wall of the car wall and covered by a covering layer, ensuring the integrity and flatness of the elevator car wall.

[0037] Preferably, the antenna 9 is disposed on the outer wall of the car wall; the direct placement of the antenna 9 on the outer wall of the car wall can also improve the signal receiving and transmitting capability of the antenna 9, thereby avoiding signal shielding by the elevator car 3, enhancing the signal, and thus improving the call quality. Further, the wireless communication device 5 is connected to the antenna 9 on the outer wall via a transmitting / receiving line 8, which passes through a wiring hole 11 in the car wall to communicate with the outside; a wiring hole 11 is directly opened on the car wall at the location of the housing 1, through which the transmitting / receiving line 8 is directly connected to the antenna 9 fixed to the outer wall, effectively shortening the length of the transmitting / receiving line 8 and reducing the difficulty of placement.

[0038] Preferably, the circuit board 2 is further provided with a power indicator light 12, a power interface 13 and an expansion interface 14. The power indicator light 12, the power interface 13 and the expansion interface 14 are electrically connected to the controller 4, and the power interface 13 is electrically connected to the power supply 15.

[0039] Preferably, it further includes: a display 16, a call button 17, and an answer button 18, wherein the display 16, the call button 17, and the answer button 18 are electrically connected to the controller 4 and are disposed in the mounting slot of the housing 1; calling and answering are realized through the call button 17 and the answer button 18, and the signal status and call status are displayed through the display 16.

[0040] Preferably, it also includes: a WiFi communicator 20 and a switching switch, wherein the switching switch is electrically connected to the controller 4 and to the WiFi communicator 20 and the wireless communicator 5; by setting the switching switch, the switching between the WiFi communicator 20 and the 4G communicator can be realized. Thus, when the WiFi signal is strong, the switch can be manually switched to the WiFi communicator 20, and when the 4G signal is strong, the switch can be manually switched to the 4G communicator, thereby realizing the adaptation to different scenarios according to the actual situation.

[0041] It's important to understand that the switch can be a single-pole double-throw switch. When the WiFi signal is strong, it connects to the WiFi communicator 20; when the 4G signal is strong, it connects to the 4G communicator.

[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
