Description

Technical Field

[0001] This utility model relates to the field of elevator control technology, and in particular to a voice elevator calling device and a voice elevator calling system. Background Technology

[0002] In public and home elevator scenarios, with increasing public health awareness, passengers' demand for "zero-contact" elevator access is becoming increasingly urgent. Traditional button-based elevator calling systems, due to frequent contact, can become a medium for the cross-transmission of bacteria and viruses. To eliminate such risks, contactless voice-activated elevator calling devices have emerged. However, existing technologies still have the following problems:

[0003] The first type of solution completely encloses the microphone inside the casing, relying solely on the casing wall or micro-holes for sound transmission. While this structure effectively blocks external dust and salt spray from entering, the micro-holes or casing wall obstruct the sound signal, resulting in significant attenuation and a decrease in the recognition rate of voice call commands. This is especially true in noisy environments inside the elevator car, where missed recognition is more likely.

[0004] The second type of design uses an open microphone hole to directly pick up sound. Although the acoustic performance is preserved, dust can easily accumulate on the microphone surface after entering through the microphone hole, potentially clogging the microphone and causing a decrease in microphone sensitivity.

[0005] Therefore, there is an urgent need to design a voice-activated elevator call device and system to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a voice-activated elevator call device and system with good sound reception and dust resistance.

[0007] To address the aforementioned technical problems, this utility model provides a voice-activated elevator call device, comprising a body panel, a body base box, and a voice transceiver. The voice transceiver is used to receive voice call signals from users and play voice prompts. The voice transceiver is located between the body panel and the body base box. The body panel has a sound receiving area with several sound receiving channels. The sound receiving channels extend upwards from the outer wall of the body panel to the inner wall of the body panel. A sound receiving cavity is provided between the sound receiving area and the voice transceiver. The two ends of the sound receiving cavity are a sound receiving port and a sound focusing port, respectively. The sound receiving port is larger than the sound focusing port. The sound receiving port is connected to the sound receiving area, and the sound focusing port is connected to the voice transceiver. A waterproof and breathable membrane is provided between the sound focusing port and the voice transceiver. The voice transceiver includes an offline voice recognition module with a built-in elevator call command dictionary.

[0008] As an improvement to the above solution, a mounting bracket for fixing the voice transceiver is also included. The mounting bracket includes a housing and a mounting plate, and the voice transceiver is disposed in the housing. The mounting plate is provided with a bracket notch and a bracket screw hole. The base box of the device is provided with a guide shaft and a base box screw hole corresponding to the bracket notch and the bracket screw hole, respectively. The bracket notch is placed on the guide shaft, and the mounting bracket is fixed in the base box of the device by means of fasteners passing through the bracket screw hole and the base box screw hole in sequence.

[0009] As an improvement to the above solution, a base plate component is also included. The base plate component has a base plate connecting part at its bottom, a first abutting part at its top, and second abutting parts on both sides. The base box of the machine body has a cable routing hole for wiring, and the base plate component has a base plate hole corresponding to the cable routing hole. A first base plate screw hole and a second base plate screw hole are provided on both sides of the base plate hole. The base box of the machine body has a base box connecting part corresponding to the base plate connecting part. A fastener passes through the base box connecting part and the base plate connecting part to fix the base box of the machine body onto the base plate component.

[0010] As an improvement to the above solution, the microphone opening is larger than the microphone area, and the bottom of the microphone opening is flush with the bottom of the lowest microphone channel in the microphone area.

[0011] As an improvement to the above solution, the diameter of the sound receiving channel is not less than 3mm.

[0012] As an improvement to the above scheme, the angle between the axis of the sound receiving channel and the horizontal plane is 30°-60°, and the angle between the inner wall of the sound receiving cavity and the horizontal plane is 30°-60°.

[0013] As an improvement to the above solution, the waterproof and breathable membrane covers the microphone port and the outer wall of the microphone port.

[0014] As an improvement to the above solution, the inner walls of the sound receiving channel and the sound receiving cavity are provided with a hydrophobic-oleophobic dual-hydrophobic nano-coating.

[0015] As an improvement to the above solution, the outer wall of the body panel is provided with a voice call icon to prompt the user to perform voice call operation.

[0016] Accordingly, this utility model also discloses a voice-activated elevator system, including the aforementioned voice-activated elevator device, a car main board, and several button adapter plates.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0032] like Figures 1-4 As shown, the voice call elevator device of this utility model includes a body panel 1, a body base box 2 and a voice transceiver 3. The voice transceiver 3 is used to receive the voice call elevator signal issued by the user and play voice prompts. The voice transceiver 3 is located between the body panel 1 and the body base box 2.

[0033] The body panel 1 is provided with a sound receiving area 11, and the sound receiving area 11 is provided with a plurality of sound receiving channels 111. The sound receiving channels 111 extend from the outer wall of the body panel 1 upwards to the inner wall of the body panel 1.

[0034] A sound receiving cavity 12 is provided between the sound receiving area 11 and the voice transceiver 3. The two ends of the sound receiving cavity 12 are a sound receiving port 121 and a sound focusing port 122, respectively. The sound receiving port 121 is larger than the sound focusing port 122. The sound receiving port 121 is connected to the sound receiving area 11, and the sound focusing port 122 is connected to the voice transceiver 3. A waterproof and breathable membrane 13 is provided between the sound focusing port 122 and the voice transceiver 3.

[0035] The voice transceiver 3 is equipped with an offline voice recognition module (not shown in the figure), which has a built-in elevator call command dictionary.

[0036] It should be noted that the voice transceiver 3 can be an integrated microphone and speaker. The specific working principles of the microphone, speaker and offline voice recognition module are existing technologies and will not be described in detail here.

[0037] This utility model's voice call ladder device is equipped with the aforementioned sound receiving cavity 12. Sound enters the sound receiving port 121 from the sound receiving channel 111 of the sound receiving area 11, and then passes through the sound focusing port 122 to reach the voice transceiver 3, which facilitates sound propagation and improves sound receiving performance. Furthermore, the inclined sound receiving channel 111 reduces dust adhesion, and the vibration of the voice transceiver 3 when playing voice prompts can expel dust, providing good dustproof performance.

[0038] In order to improve the sound reception efficiency, the sound reception port 121 is larger than the sound reception area 11, so that the sound reception port 121 covers at least the entire area of ​​the sound reception area 11;

[0039] The bottom of the microphone port 121 is flush with the bottom of the bottommost microphone channel 111 in the microphone area 11, allowing dust to slide off naturally along the channel formed by the microphone port 121 and the microphone channel 111. The structure of the microphone port 121 being greater than or equal to the area of ​​the microphone area 11 and having a flush bottom eliminates the dead zones where dust easily accumulates in traditional micropores or recessed areas. Dust can slide off naturally due to gravity, keeping the acoustic channel unobstructed and maintaining a high recognition rate.

[0040] The diameter of the sound receiving channel 111 is not less than 3mm to ensure that dust is discharged smoothly and to ensure long-term stable transmission of sound signals.

[0041] The angle ∠A between the axis L of the receiving channel 111 and the horizontal plane is 30°-60°, and the angle ∠B between the inner wall of the receiving cavity 12 and the horizontal plane is 30°-60°. The 30°-60° inclined receiving channel 111 and the inner wall of the receiving cavity 12 form a slope, making it difficult for dust particles to remain under the action of gravity and airflow, thus achieving passive self-cleaning.

[0042] Preferably, the waterproof and breathable membrane 13 covers the microphone 121 and its outer wall, preventing liquid water and salt spray from entering and blocking large-particle dust.

[0043] The inner walls of both the sound receiving channel 111 and the sound receiving cavity 12 are coated with a hydrophobic-oleophobic dual-coating. This hydrophobic-oleophobic dual-coating provides dust protection, primarily based on the following characteristics: by altering the surface properties of the material, dust is made difficult to adhere to. When dust particles come into contact with the coating surface, they are difficult to remain due to surface energy differences. Even if a small number of particles fall in, they can quickly detach with airflow or vibration, thus maintaining the microphone's sensitivity and acoustic performance over a long period.

[0044] The outer wall of the body panel 1 is provided with a voice call sign 14 to prompt users to make voice calls. This visually guides passengers to directly aim their voice at the receiving area, improving efficiency.

[0045] Regarding the installation method of the voice transceiver 3:

[0046] like Figure 5 and Figure 6 As shown, the voice call elevator device of this utility model also includes a mounting bracket 4 for fixing the voice transceiver 3. The mounting bracket 4 includes a housing 41 and a mounting plate 42, and the voice transceiver 3 is disposed in the housing 41.

[0047] The mounting plate 42 is provided with a bracket notch 421 and a bracket screw hole 422. The base box 2 of the machine body is provided with a guide shaft 21 and a base box screw hole 22 corresponding to the bracket notch 421 and the bracket screw hole 422 respectively. The bracket notch 421 is placed on the guide shaft 21. The mounting bracket 42 is fixed in the base box 2 of the machine body by means of a fastener passing through the bracket screw hole 422 and the base box screw hole 22 in sequence.

[0048] Regarding the specific installation method of the voice call elevator device of this utility model:

The double-sided adhesive hole 61 is connected to one side of the double-sided adhesive 6, forming a double-sided adhesive opening 62. The double-sided adhesive opening 62 passes through the wiring of the voice call device, and the base box 2 is attached to the car main board 20 by the double-sided adhesive 6. The first installation method is more suitable for temporary fixing.

[0050] like Figure 8 As shown, the second installation method involves creating screw holes in the base box 2 and the car main board 20, and then fixing the voice call device to the car main board 20 by passing screws through the screw holes in both the car main board 20 and the base box 2.
