[0008] As a preferred embodiment of the walkie-talkie used in the elevator wireless intercom system of the present invention, the video intercom unit includes a video intercom set on the mounting slot, a fixed block and a movable block set on the video intercom and cooperating with the locking block, and the gap between the fixed block and the movable block is set as a locking groove; the fixed block is slidably set on the video intercom, and the width of the locking groove changes with the sliding of the movable block.

[0009] As a preferred embodiment of the walkie-talkie for the elevator wireless intercom system of the present invention, the following features are provided: the card block is provided with a third inclined surface and a carding surface; the fixed block is provided with a first inclined surface for engaging with the third inclined surface; and the movable block is provided with a second inclined surface for engaging with the third inclined surface.

[0010] As a preferred embodiment of the walkie-talkie for the elevator wireless intercom system of the present invention, the control component includes a connecting block 1 disposed on the mounting plate, a support block disposed on the mounting plate, and a support spring 3 whose two ends are respectively fixedly connected to the connecting block 1 and the support block; the mounting plate is provided with a lifting groove for cooperating with the connecting block 1.

[0011] As a preferred embodiment of the walkie-talkie for the elevator wireless intercom system of the present invention, the drive assembly includes a telescopic rod rotatably mounted on a connecting block, a movable rod 1 mounted on the telescopic rod, a rotating shaft 1 mounted on the movable rod 1, a movable rod 2 mounted on one side of the movable rod 1, the bottom end of the movable rod 2 being slidably connected to the movable rod 1, and a rotating shaft 2 mounted on the movable rod 2.

[0012] As a preferred embodiment of the walkie-talkie for the elevator wireless intercom system of the present invention, the safety component includes a sliding block disposed on the mounting plate, a limiting block disposed on the sliding block, a connecting block II disposed on the sliding block, a baffle disposed on the sliding block, and an abutting block disposed on the sliding block; the mounting plate is provided with a limiting groove for cooperating with the limiting block.

[0013] As a preferred embodiment of the walkie-talkie for the elevator wireless intercom system of the present invention, the sliding block is provided with a rotating groove, and the rotating groove is provided with a rotating shaft three; the movable rod two is provided with a sliding groove for cooperating with the rotating shaft three.

In case of an emergency, passengers can easily remove the video intercom and hold it to their mouth to make a call. By bringing the microphone close to the sound source, the pickup distance is shortened from 0.5-1 meter for the fixed type to 5-10 centimeters. This avoids the problem of unclear voice caused by the long distance and noisy environment of traditional fixed intercoms, ensuring that the distress information is accurately transmitted. After the video intercom is removed, passengers can move the intercom to the best signal position in the elevator according to the instructions of the security personnel, actively avoiding signal blind spots. The security personnel can guide passengers to point the intercom camera at the status of trapped people, abnormal parts of the top of the car, or gaps in the hall door to achieve visualized remote fault diagnosis. Meanwhile, the video intercom unit and the mounting plate adopt a modular snap-fit ​​structure, allowing maintenance personnel to complete the replacement of the entire unit within 10 seconds without disassembling the mounting plate or rewiring. The built-in charging structure of the mounting plate ensures that the intercom is always fully charged and ready for use. Through the acceleration adaptive design of the supporting spring three, the safety unit structure remains stable when the elevator slides or shakes slightly, preventing accidental triggering due to vibration. When it needs to be removed, the inclined surface three of the locking block cooperates with the inclined surface two of the moving block to achieve the operation logic of pressing to lock and pressing again to unlock, which conforms to the human body's instinctive reaction in an emergency and avoids delays in calling for help due to complicated operations.

Detailed Implementation

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides an intercom for an elevator wireless intercom system, which includes a mounting plate 1 for mounting on the elevator, a video intercom unit 2 set on the mounting plate 1 for connecting to the intercom system to facilitate communication between passengers and security personnel in the elevator, a connection unit 3 set on the video intercom unit 2 for installing and removing the video intercom unit 2, and a safety unit 4 set on the connection unit 3 for securing the video intercom unit 2 locked on the connection unit 3 to prevent accidental contact by passengers that would cause the video intercom unit 2 to unlock and fall off. The safety unit 4 includes a control component 41 mounted on the mounting plate 1, a drive component 42 mounted on the control component 41, and a safety component 43 mounted on the drive component 42. The control component 41 is used to drive the drive component 42 to move, thereby simultaneously locking or unlocking the connection between the connection unit 3 and the video intercom unit 2 by the safety component 43.

[0028] In summary, first, fix the connecting unit 3 onto the mounting plate 1, then install the mounting plate 1 onto the elevator. Next, pull the safety unit 4 to fully open the mounting port on the connecting unit 3. Then, insert the video intercom unit 2 into the connecting unit 3. The connecting unit 3 engages the video intercom unit 2. Release the safety unit 4, which locks the connecting unit 3 in place. The video intercom unit 2 cannot be removed from the connecting unit 3 without unlocking the safety unit 4. In case of an emergency in the elevator, the passenger pulls the safety unit 4 to release the lock on the connecting unit 3. Then, press the video intercom unit 2. The interaction between the video intercom unit 2 and the connecting unit 3 locks them together. Simultaneously, quickly remove the video intercom unit 2 to communicate with security personnel, allowing them to fully understand the situation and implement rescue measures.

[0029] Example 2, refer to Figure 1 - Figure 6 This is the second embodiment of the present invention. Unlike the previous embodiment, it provides a specific structure for the connecting unit 3 in the intercom for an elevator wireless intercom system. Compared to embodiment 1, the connecting unit 3 further includes a mounting slot 31 on a mounting plate 1 for mounting the video intercom unit 2, for placing the video intercom unit 2; an abutment plate 32 on the mounting slot 31 for abutting the video intercom unit 2; a charging structure on the abutment plate 32, allowing the video intercom unit 2 to be charged after it is fully abutted against the abutment plate 32, ensuring the video intercom unit 2 remains active for a certain period after being removed; a support spring 33 fixedly connected at both ends to the mounting slot 31 and the abutment plate 32 respectively, for driving the abutment plate 32 to firmly abut the video intercom unit 2; and a locking component 34 on the mounting slot 31 for locking and unlocking the video intercom unit 2.

[0030] The latching assembly 34 includes a latching block 341 disposed on the mounting groove 31 to latch and fix the video intercom unit 2; a movable cavity 342 disposed on the mounting groove 31 to cooperate with the latching block 341 for moving up and down when the latching block 341 is subjected to a vertical force; a guide post 343 disposed in the movable cavity 342 and slidably connected to the latching block 341 for limiting the sliding of the latching block 341; and a second support spring 344 whose two ends are fixedly connected to the bottom of the latching block 341 and the movable cavity 342 respectively for providing support and providing an upward force to the latching block 341.

[0031] The video intercom unit 2 includes a video intercom 21 mounted on the mounting slot 31 for communication between elevator passengers and security personnel. The video intercom 21 is equipped with a charging interface. When the video intercom 21 is firmly abutted against the abutting plate 32, the interface is connected to the charging structure to charge the video intercom 21. The video intercom 21 is also equipped with a fixed block 22 and a movable block 23 that cooperate with the locking block 341. The fixed block 22 and the movable block 23 are used to generate a vertical force on the locking block 341, causing the locking block 341 to move up and down. The gap between the fixed block 22 and the movable block 23 is set as a locking groove 24 for locking the locking block 341. Together with the abutting plate 32, the video intercom 21 is fixed on the mounting slot 31. The fixed block 22 is slidably mounted on the video intercom 21. The width of the slot 24 changes as the movable block 23 slides. When the slot 341 passes the movable block 23, the support spring 344 drives the slot 341 to release into the slot 24, squeezing the fixed block 22 open, so that the video intercom 21 cannot be directly taken out of the mounting slot 31.

[0032] Among them, the card block 341 is provided with a slope 3411 and a snap-fit ​​surface 3412. The slope 3411 is used to generate a vertical force when it is squeezed, which drives the card block 341 to move downward. The snap-fit ​​surface 3412 is used to cooperate with the card slot 24 to snap-fit, so that the video walkie-talkie 21 cannot be directly pulled out from the mounting slot 31. The fixed block 22 is provided with an inclined surface 221 for cooperating with the inclined surface 3411. The inclined surface 221 is used to generate a vertical force on the locking surface 3412, which drives the locking block 341 to move downward. The movable block 23 is provided with a second inclined surface 231 for cooperating with the third inclined surface 3411. The second inclined surface 231 is used to abut against the third inclined surface 3411, causing the locking block 341 to move downward.

[0033] The rest of the structure is the same as in Example 1.

[0034] In summary, after the mounting plate 1 is installed on the elevator, the safety unit 4 is pulled to fully open the mounting slot 31. The video intercom 21 is then pressed into the mounting slot 31, where it abuts against the abutment plate 32 and compresses the first support spring 33. Simultaneously, the second inclined plane 231 compresses the third inclined plane 3411, causing the locking block 341 to move into the movable cavity 342. At this time, the second support spring 344 is compressed. As the second inclined plane 231 passes... After the inclined plane 3411 is in place, the supporting spring 344 is released, causing the locking surface 3412 to enter the slot 24. At this time, the locking surface 3412 abuts against the side of the movable block 23 near the slot 24. If the video intercom 21 is pulled outward at this time, it cannot be pulled out directly due to the abutment between the locking surface 3412 and the inner wall of the movable block 23. At this time, the safety unit 4 is released, fixing the position of the locking block 341 to prevent accidental activation of the video intercom 21 and causing the locking block to be locked. When the locking mechanism 341 engages, the video intercom 21 is dislodged from the mounting slot 31. When it is necessary to remove the video intercom 21, the locking mechanism 341 is released via the safety unit 4. Pressing the video intercom 21 further causes the fixing block 22 to push the locking block 341 towards the movable cavity 342 via the inclined surface 3411 until the inclined surface 3411 contacts the inclined surface 221. Then, pulling the video intercom 21 outwards releases the pressure from the inclined surface 3411. Push the fixed block 22 toward the movable block 23 until the fixed block 22 contacts the movable block 23, closing the slot 24. At this time, the fixed block 22, through the action of the inclined surface 221 and the snap-fit ​​surface 3412, squeezes the snap-fit ​​block 341 into the movable cavity 342 until the snap-fit ​​surface 3412 completely leaves the inclined surface 221. At this time, under the action of the second support spring 344, the snap-fit ​​block 341 extends and contacts the inclined surface 231. At this time, the video intercom 21 can be removed from the mounting slot 31.

[0035] Example 3, referring to Figure 1 - Figure 8This is the second embodiment of the present invention. Unlike the previous embodiment, it provides a specific structure for the safety unit 4 in the intercom of the elevator wireless intercom system. Compared to embodiment 2, the control component 41 further includes a connecting block 411 mounted on the mounting plate 1 for hand-pulling, a support block 412 mounted on the mounting plate 1 for fixing, and a support spring 413 fixedly connected at both ends to the connecting block 411 and the support block 412 respectively, which supports and restores the connecting block 411. When the elevator descends normally, the acceleration is very small and will not change the overall shape of the support spring 413. When the elevator loses traction and falls directly, without considering friction, the overall acceleration of the elevator is G. Considering the support spring 413 and the elevator car as a whole, and in conjunction with the elevator system's buffer locking device, the elevator will jam at the next floor elevator entrance. At this time, the impact of the falling elevator will not deform the spring, and the safety unit 4 can still be used normally. The mounting plate 1 is provided with a lifting groove 11 for cooperating with the connecting block 411, which serves as the path for the connecting block 411 to move up and down.

[0036] The drive assembly 42 includes a telescopic rod 421 rotatably mounted on the connecting block 411, a movable rod 422 mounted on the telescopic rod 421, a rotating shaft 423 mounted on the movable rod 422, a movable rod 424 mounted on one side of the movable rod 422, the bottom end of the movable rod 424 being slidably connected to the movable rod 422, and a rotating shaft 425 mounted on the movable rod 424. When the connecting block 411 moves up and down, it causes the movable rod 422 to deflect around the rotating shaft 423. At this time, the telescopic rod 421 is adjusted for adaptive length. The side of the movable rod 422 closest to the movable rod 424 is set as an inclined rod, which is used to drive the movable rod 424 to rotate around the rotating shaft 425 when rotating, thereby driving the safety assembly 43 to move.

[0037] The safety component 43 includes a sliding block 431 on the mounting plate 1 for moving in coordination with the drive of the second movable rod 424; a limiting block 432 on the sliding block 431 for sliding on the mounting plate 1; a connecting block 433 on the sliding block 431 for connecting; a baffle 434 on the sliding block 431 for covering the gap between the locking block 341 and the fixed block 22 in coordination with the movement of the sliding block 431; and an abutment block 435 on the sliding block 431 for supporting the locking block 341 and the movable cavity 342 in coordination with the movement of the sliding block 431, thereby fixing the state of the locking block 341. The mounting plate 1 is provided with a limiting groove 12 for cooperating with the limiting block 432. The sliding block 431 moves back and forth through the cooperation of the limiting block 432 and the limiting groove 12.

[0038] The sliding block 431 is provided with a rotating groove 4311, and the rotating groove 4311 is provided with a rotating shaft 4312. The rotating groove 4311 provides space for the movable rod 424 to rotate, and the rotating shaft 4312 is used to connect the sliding block 431 and the movable rod 424. The movable rod 2 424 is provided with a sliding groove 4241 for cooperating with the rotating shaft 3 4312. The sliding groove 4241 is used to adapt the rotating shaft 3 4312 to slide on the sliding groove 4241 when the movable rod 2 424 rotates.

[0039] When the baffle 434 is in the released state, the abutment block 435 enters the movable cavity 342, and its two ends abut against the locking block 341 and the bottom of the movable cavity 342 respectively. This setting fixes the position of the locking block 341. When the video intercom 21 is pushed, the compression of the locking block 341 by the fixing block 22 and the movable block 23 prevents the locking block 341 from moving up and down.

[0040] The rest of the structure is the same as in Example 2.

[0041] In summary, when installing the video intercom 21, pull down the connecting block 411. This compresses the support spring 413, causing the connecting block 411 to rotate the movable rod 422 around the pivot 423. The telescopic rod 421 then changes its length to accommodate the movement. The rotation of the movable rod 422 causes the movable rod 424 to rotate around the pivot 425. Through the sliding groove 4241 and the pivot 4312, the sliding block 431 is pulled outwards, causing the baffle 434 and the abutment block 435 to retract into the mounting groove 31. At this point, the video intercom 21 can be directly installed. Press the device into the mounting slot 31. The video intercom 21 is installed through the cooperation of the locking block 341 and the slot 24. At this time, release the connecting block 1 411. Through the restoration of the support spring 3 413, and with the action of the movable rod 1 422 and the movable rod 2 424, the baffle 434 and the abutment block 435 are driven back to their original positions. At this time, the baffle 434 covers the gap between the locking block 341 and the fixing block 22, and the abutment block 435 enters the movable cavity 342 to support the locking block 341 and the movable cavity 342. At this time, the video intercom 21 cannot be pulled out directly from the mounting slot 31.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
