Description

Technical Field

[0001] This invention relates to the field of special vehicles, specifically to a multi-radio centralized monitoring and communication mobile device. Background Technology

[0002] With the advancement of modern science and technology, special vehicles such as communication vehicles have been widely used in various fields. Communication vehicles are widely used in urban and field environments; they not only have mobile carrying functions but are also widely used in detection, transportation, rescue, and other fields, utilizing their built-in communication functions and various auxiliary equipment to perform multiple tasks. Faced with complex environments, there is still considerable room for improvement in the research of special vehicles.

[0003] In practical engineering work, the following problems exist:

[0004] I. Existing communication vehicles typically feature communication cabinets to house various communication devices such as radios. To cope with complex environments, such as high-altitude areas, they may also be equipped with oxygen generators. However, unlike civilian equipment that can be placed arbitrarily, the space inside the vehicle is limited, necessitating centralized placement, such as in an electrical cabinet. Furthermore, power connections within the vehicle are often centrally located. Therefore, electrical equipment is often placed in a centralized manner. The cabinets generally have doors, and during centralized placement, the cabinet doors contain compartments for storing oxygen generators or similar components. The oxygen generator outputs oxygen through connecting pipes, and the cabinet doors have openings for these connecting pipes to extend out.

[0005] In actual use, since the communication cabinet of the communication vehicle is not specifically manufactured for housing oxygen generators, and the oxygen generator is not a standard required component but is purchased later, the above-mentioned openings are often made slightly larger to accommodate more types of functional equipment. Therefore, the diameter of the opening does not match the diameter of the oxygen generator connecting pipe, and the opening size cannot be used for various specifications of oxygen generators or various types of functional equipment.

[0006] Second, as mentioned above, even if the connecting pipes are adapted to the holes on the cabinet door through intermediate adapters such as nozzles and connectors installed on the cabinet door, the structure and size of the nozzles often lead to unexpected spatial interference between the connecting pipes, connectors and nozzles during the opening of the cabinet door.

[0007] Third, cabinet doors commonly seen by the public include handles or opening and closing slots to fit hand shapes and facilitate gripping and opening / closing; however, additional processing is required to create the structure.

[0008] Fourth, as mentioned above, the connecting pipe is not directly connected to the end nozzle, but is connected in the middle through a joint. The joint is often rigid and heavy, requiring an additional support structure. The force point of this support structure is set on the cabinet door, which has the disadvantage of affecting the flexibility and space of the cabinet door.

[0009] Fifth, as mentioned above, the joint not only needs support, but also needs to be fixed by a fixed structure to prevent it from swinging back and forth or left and right. Existing technologies address this by using clamps, but the form of the clamps is limited and cannot be used more flexibly to clamp different structural environments.

[0010] VI. Currently, the audio signal monitoring and voice communication functions of each radio station in the existing communication vehicle require separate operation of the headset microphone group for each station. During operation, only one radio station's audio signal can be monitored at a time. Furthermore, the audio signals of the existing communication vehicle radios lack power amplifiers or speakers, or the volume is too low, making them difficult to monitor. Summary of the Invention

[0011] To overcome the above problems, the present invention proposes a solution that addresses multiple problems simultaneously.

[0012] The technical solution adopted by this invention to solve its technical problem is as follows: a multi-station centralized monitoring and communication mobile device, including a vehicle body, a communication cabinet in the vehicle body, an electrical cabinet in the communication cabinet, and a multi-station centralized communication device placed on the communication cabinet; an oxygen generator is placed in the electrical cabinet, and the air outlet of the oxygen generator is connected to a connecting device; the multi-station centralized communication device includes a main body, an audio output unit, an indicator light, an audio selection switch, a volume adjustment knob, a microphone interface, a controller, and a communicator; the indicator light indicates the corresponding radio station signal; the audio selection switch can select different radio station signals for communication, and the audio selection switch includes a mixed audio mode. When the audio selection switch is in the mixed audio mode, the audio output unit can monitor the audio signals of all radio stations, and the flashing of the indicator light can indicate which channel or channels have an audio signal input;

[0013] The connecting device includes a connecting pipe, a connector, a clamping support module, and a nozzle; the electrical cabinet includes a cabinet door with a cabinet hole at the opening end of the door, located at the upper right corner of the door; the nozzle includes a spray pipe, a sleeve, a stepped portion, and a handle; the clamping support module includes a support plate and a clamping component, the clamping component including an arc portion, a lower connecting plate, a horizontal plate, and an upper connecting plate; the lower end of the arc portion is connected to the lower connecting plate, the upper end of the arc portion is connected to the horizontal plate, the right end of the horizontal plate is connected to the upper connecting plate, and the upper connecting plate extends vertically;

[0014] One end of the connecting pipe is connected to the air outlet, and the other end is connected to one end of the connector. The other end of the connector abuts against the nozzle. The connector is fixed by the clamping support module. The support plate is connected to the inner side of the right wall of the electrical cabinet. The length of the support plate extending out of the right wall is less than the diameter of the connector. When the connector is fixed, the support plate supports the connector from below. The arc part abuts against the connector. The lower connecting plate is connected to the support plate through a connector. Similarly, the upper connecting plate is connected to the right wall through a connector.

[0015] The diameter of the nozzle is larger than the diameter of the sleeve. The nozzle and the sleeve are connected by a stepped portion, and the handle is connected to the stepped portion. The handle is located inside the nozzle. The other end of the connector abuts against the stepped portion. The sleeve is located inside the connector, and there is a gap between the sleeve and the connector. The diameter of the sleeve is smaller than the diameter of the connector. The nozzle is threaded into the cabinet hole to facilitate adjustment of the positional relationship between the nozzle and the cabinet door. When the cabinet door is rotated and opened, there is no interference between the sleeve and the connector.

[0016] Preferably, the length of the sleeve is less than the length of the nozzle.

[0017] Preferably, the length of the sleeve is less than the thickness of the cabinet door.

[0018] Preferably, the cabinet door is opened by rotating.

[0019] Preferably, after the joint is fixed, there is a gap between the cross plate and the joint.

[0020] Preferably, the axis of the handle coincides with the center line of the sleeve.

[0021] Preferably, a sealing ring is provided on the stepped portion.

[0022] Preferably, the joint abuts against the sealing ring.

[0023] Preferably, the connection between the handle and the step is a detachable connection.

[0024] Preferably, after the handle is removed, a filter screen is detachably installed in the nozzle.

[0025] The beneficial effects of this invention are:

[0026] I. Regarding the first point raised in the background technology, by setting up a nozzle and connector with a double-sleeve structure, the large and small sleeves in the double-sleeve structure are connected to each other, and a step is set in the middle of the large and small sleeves. The small sleeve extends into the connector, and the connector rests on the step. The size of the large sleeve is adapted to the cabinet door hole and is connected to the cabinet door hole, thereby adapting the size of the output pipe and the connector to the size of the cabinet door hole.

[0027] Second, regarding the second point raised in the background technology, the cabinet door hole is set at the rotating opening end of the cabinet door, and there is a radial gap between the small sleeve and the connector after they are sleeved together. Because it is set at the opening end and the length of the small sleeve is relatively short, even if the cabinet door is opened a short distance, the turning angle of the cabinet door is relatively small, and the corresponding rotation angle of the cabinet door hole and the nozzle is also relatively small. Therefore, the short small sleeve in the nozzle deflects less and will not interfere with the connector.

[0028] Thirdly, regarding the third point raised in the background technology, there is no need to additionally process the grip groove on the cabinet door; the handle rod can be directly connected to the inner side of the step between the large and small sleeves, which reduces the processing difficulty and steps of the handle structure.

[0029] Fourthly, regarding the fourth point raised in the background technology, although the cabinet door is a component directly related to the joints and support structure, the design concept has been changed, and the support structure is set on the cabinet wall. For the cabinet wall, which is a fixed component, it is reasonable to add an extra structure. Therefore, there is no need to set an extra structure on the cabinet door, so as to reduce the redundant structure of the cabinet door and make the flexibility and space of the cabinet door movement better.

[0030] Fifth, in response to the fifth point raised in the background technology, a single-clamp fixture is provided to adapt to the right-angle installation environment formed by the support structure and the cabinet wall. At the same time, the length of the support structure is appropriately shortened to facilitate docking with the single clamp or adjustment of the clamping size.

[0031] VI. Regarding point six in the background technology, a centralized monitoring and voice communication technology for multiple radio audio signals from a communication vehicle is provided, enabling simultaneous monitoring of multiple radio audio signals. It can amplify and output the radio audio signals, facilitating easy monitoring.

[0032] Note: The above designs are not in any particular order, and each one makes the present invention different from the prior art and a significant advancement. Attached Figure Description
