Description

Technical Field

[0001] This utility model relates to the field of emergency command equipment technology, specifically to a portable emergency command terminal device. Background Technology

[0002] Portable emergency command terminals typically adopt a box-type structure, with the display screen, keyboard, control buttons, and electronic control components all housed inside the box, so that they can be carried to the emergency site for information viewing, command input, and on-site dispatch.

[0003] During emergency operations, in addition to the command terminal, it is usually necessary to carry items related to the emergency mission, such as spare batteries, handheld microphones, external antennas, and connecting cables. Currently, the operating components of the terminal and emergency supplies are often carried separately, resulting in insufficient overall integration. Although some equipment has storage space inside the enclosure, the storage space lacks a reasonable hierarchical arrangement with the terminal operating area. Retrieving or placing emergency supplies may require moving the operating components, or placing emergency supplies in the same space as the electronic control components, which is not conducive to the orderly use of the internal space of the enclosure.

[0004] Furthermore, the display screen and the terminal operating structure used to cover the storage space have different opening requirements. If both use the same opening or locking method, it is inconvenient to control the opening status of the terminal operating area and the storage area separately. Therefore, it is necessary to improve the internal hierarchy and locking structure of the portable emergency command terminal. Utility Model Content

[0005] The purpose of this utility model is to provide a portable emergency command terminal device, which forms a terminal operation area and an emergency supplies storage area that are separated within the housing, and allows the display screen and the storage area to be opened and locked respectively.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A portable emergency command terminal device includes a housing with a mounting recess on one side. A terminal operation layer is embedded in the mounting recess, and a storage layer is located on the side of the terminal operation layer facing the interior of the housing. The terminal operation layer can be opened relative to the housing to expose the storage layer located inside it.

[0007] The terminal operation layer is equipped with an operation panel, and the display screen is rotatably mounted on the housing and located in the middle of the terminal operation layer. The display screen has a folded state and a flip-open state. When the display screen is folded, it covers the operation panel; when the display screen is flipped open, it exposes the operation panel.

[0008] The enclosure is also equipped with a locking assembly, which includes a latch, a combination lock, and a locking pin. The latch is rotatably mounted on the free end of the display screen and can engage with the terminal operation layer; the locking pin is located on one side of the latch and can be moved to a position that prevents the latch from rotating; the combination lock is located between the terminal operation layer and the enclosure to prevent the terminal operation layer from being opened relative to the enclosure.

[0009] Furthermore, an electronic control component is provided on the side of the control panel facing the storage layer. A partition is provided between the electronic control component and the storage layer. The partition is connected to the terminal control layer to separate the electronic control component from the storage layer.

[0010] Furthermore, the storage layer is equipped with a storage panel located on the side of the partition away from the electronic control components and spaced apart from the partition. Emergency supplies are placed on the storage panel.

[0011] Furthermore, one side of the display screen is rotatably positioned at the edge of the mounting recess, while the other side of the display screen forms a free end, with the operation panel located within the flip-cover range of the display screen.

[0012] Furthermore, the latch is rotatably mounted on the free end of the display screen via a pivot, and the latch has a slot. The latch can elastically deform during the fastening process, allowing the corresponding edge of the terminal operation layer to enter the slot, and after the latch returns to its original shape, the slot prevents the display screen from opening.

[0013] Furthermore, a fixed shaft is fixed to the free end of the display screen, and the locking pin has a sleeve that slides on the fixed shaft, with a stop seat on the sleeve. A fixed seat corresponding to the sleeve is provided on the terminal operation layer, and the sleeve can move relative to the fixed shaft and pass into or out of the fixed seat.

[0014] Furthermore, a stop plate is provided on the fixed shaft, located on the side of the ferrule opposite to the stop seat, to prevent the ferrule from disengaging from the fixed shaft. A spring is fitted on the fixed shaft, abutting against the stop seat and pushing the ferrule towards the fixed seat. A pin hole is provided on the fixed seat for the ferrule to pass through, restricting the rotation of the latch when the ferrule is inserted into the pin hole. An actuating groove is provided on the stop seat, which allows the stop seat and the ferrule to move against the spring force, causing the ferrule to exit the pin hole.

[0015] Compared with the prior art, this utility model stacks the terminal operation layer and the storage layer along the inside and outside of the box, so that the terminal operation components and emergency supplies can be integrated into the same box. The storage layer is covered by the terminal operation layer, which helps to improve the utilization rate of the internal space of the box.

[0016] The display screen can flip independently of the terminal operation layer, so that the exposure of the control panel does not depend on the opening of the storage layer, thus giving the terminal operation area and the storage area a relatively independent opening relationship. The partition separates the electronic control components from the storage layer, which helps to reduce the mutual interference between emergency supplies and electronic control components.

[0017] The combination of latches and locking pins restricts the opening of the display screen, while the combination lock restricts the opening of the terminal operation layer relative to the cabinet. This creates a hierarchical locking relationship between the display screen and the storage layer, which helps reduce the possibility of the display screen or terminal operation layer being accidentally opened during transportation.

[0020] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application.

[0021] like Figure 1 , Figures 5 to 7 As shown, this embodiment provides a portable emergency command terminal device, including a housing 1. A mounting recess is formed on one side of the housing 1, and a terminal operation layer 11 is embedded within the mounting recess. A storage layer 12 is formed on the side of the housing 1 facing inwards from the terminal operation layer 11. One side of the terminal operation layer 11 is rotatably connected to the housing 1, allowing the terminal operation layer 11 to flip between a closed position and an open position. When the terminal operation layer 11 is in the closed position, it covers the opening of the storage layer 12; when the terminal operation layer 11 is flipped open relative to the housing 1, the storage layer 12 is exposed, allowing for the retrieval and placement of emergency items 3 stored within the storage layer 12.

[0022] The housing 1 can be made of a lightweight material with a certain strength, and its outer contour is a box-shaped structure that facilitates handling and placement. Corner guards 13 are provided at the corners of the housing 1, covering areas of the housing 1 that are susceptible to impact, to reduce the impact of external forces on the corners of the housing 1 during transportation, handling, or on-site use. Handles 14 are provided on the outer side of the housing 1 for users to lift the equipment; when the equipment is placed in use, the handles 14 can be close to the outside of the housing 1 to minimize the occupation of the operating area.

[0023] A sealing gasket can also be provided at the joint edge between the terminal operation layer 11 and the housing 1 to press the opening of the storage layer 12 tightly when the terminal operation layer 11 is closed. After the terminal operation layer 11 is closed, its outer surface is basically flush with the upper periphery of the housing 1, so that the terminal operation layer 11 constitutes both the mounting base of the terminal and the openable cover of the storage layer 12. The rotatable connection position between the terminal operation layer 11 and the housing 1 can be set on the rear side of the mounting recess, so that the terminal operation layer 11 will not occupy the front area where the handle 14 is located when it is flipped backward.

[0024] like Figure 5 and Figure 6As shown, the terminal operation layer 11 is provided with a display screen 111 and an operation panel 112. One side of the display screen 111 is mounted on the terminal operation layer 11 near the edge of the mounting recess via a rotating connector, while the other side forms a free end. The display screen 111 can rotate between a retracted state and a flip-open state. The operation panel 112 is located within the flip-open coverage area of ​​the display screen 111. When the display screen 111 is in the retracted state, it covers at least a portion of the operation panel 112 to shield and protect the operating components on the operation panel 112. When the display screen 111 is flipped open, the operation panel 112 is exposed, allowing the user to observe the display screen 111 and operate the operation panel 112.

[0025] A damped hinge or a rotating connector with limiting capability can be used between the display screen 111 and the terminal operation layer 11 to maintain a suitable viewing angle after the display screen 111 is opened. The opening angle of the display screen 111 can be adjusted according to the user's viewing position, so that the display content can be viewed normally when the device is placed on a desktop, vehicle platform, or temporary command platform.

[0026] The control panel 112 can be equipped with a keyboard area, a touch area, and a function control area. The keyboard area is used to input text, numbers, or commands; the touch area is used to control the cursor on the display interface; and the function control area can include a power button, volume control, communication button, indicator lights, and shortcut operation buttons. All of the above operating components are located on the outer side of the control panel 112, so that the display screen 111 can be used directly after it is turned on.

[0027] The various operating components on the control panel 112 can be arranged in zones according to their frequency of use. For example, the keyboard area can be located in the center of the control panel 112, the touch area can be located on the side of the keyboard area closer to the display screen 111 or away from the display screen 111, and the function control areas can be located on both sides of the keyboard area. Frequently used power buttons, communication buttons, or volume controls can be placed in locations easily accessible to users for quick operation in emergency situations.

[0028] like Figure 6 and Figure 7 As shown, an electronic control assembly 113 is provided on the side of the operation panel 112 facing the storage layer 12. The electronic control assembly 113 can be mounted on the back side of the operation panel 112 via a support column, mounting base, or fasteners, and can be flipped together with the terminal operation layer 11. The electronic control assembly 113 may include a control motherboard, a data storage module, a communication module, a power management module, an audio processing module, an interface module, and a connection harness.

[0029] The control motherboard processes the information input or output from the display screen 111 and the operation panel 112. The data storage module stores task information, on-site data, or operation records. The communication module completes data transmission between the terminal and external devices. The power management module manages the power supply to the display screen 111, the operation panel 112, and other electrical components. Depending on the actual configuration, the electrical control component 113 can also be connected to a microphone, speaker, camera, data interface, or power interface.

[0030] A partition 114 is provided between the electronic control component 113 and the storage layer 12. The partition 114 is connected to the terminal operation layer 11 and blocks the side of the electronic control component 113 facing the storage layer 12, so that the electronic control component 113 and the emergency supplies 3 are in a separate space. Therefore, when the terminal operation layer 11 is flipped open or the box 1 is moved and vibrated, the emergency supplies 3 are less likely to directly collide with the electronic control component 113 and its connecting harness.

[0031] The partition 114 can be detachably installed on the terminal operation layer 11 using screws, clips, or a sliding groove structure, so that the partition 114 can be removed for maintenance of the electrical control assembly 113 when needed. The partition 114 may also be provided with wiring holes or heat dissipation holes, and the wire harness passing through the wiring hole can be covered with a wire sleeve to reduce friction between the wire harness and the edge of the partition 114.

[0032] The wiring harness of the electronic control component 113 can be centrally arranged along the back side of the operating panel 112 or the edge of the partition 114, and constrained by wire clamps to prevent the wiring harness from entering the rotating connection position during the flipping of the terminal operating layer 11. The gap between the partition 114 and the storage plate 121 constitutes the effective accommodating space of the storage layer 12. This gap should be adapted to the height of the emergency item 3 protruding from the surface of the storage plate 121, so that the partition 114 will not continuously compress the emergency item 3 after the terminal operating layer 11 is closed.

[0033] like Figure 7 As shown, a storage panel 121 is provided in the storage layer 12. The storage panel 121 is located on the side of the partition 114 away from the electronic control component 113 and is spaced apart from the partition 114. The storage panel 121 may be made of soft elastic material, foamed cushioning material, or a combination of soft layer and support layer.

[0034] The storage panel 121 has multiple positioning grooves on the side facing the opening of the storage layer 12. The outline of each positioning groove matches the shape of the corresponding emergency item 3, allowing the emergency item 3 to be embedded in the corresponding positioning groove. The sidewalls of the positioning grooves cover and limit the corresponding items, reducing the movement, collision, or mutual compression of the emergency items 3 within the storage layer 12 when the box 1 is lifted, tilted, or subjected to vibration. When the storage panel 121 is made of soft or foamed material, it can also cushion the surface of the items.

[0035] The depth of the positioning groove can be less than the overall height of the corresponding item, allowing part of the item to protrude from the surface of the storage panel 121 for easy grabbing by the user. A retrieval notch can also be provided in a portion of the positioning groove, allowing the user to insert their fingers and retrieve the item.

[0036] The storage panel 121 can be integrally embedded in the storage layer 12 and abut against the side wall of the storage layer 12 through its own elasticity. Alternatively, it can be installed in a detachable manner so that storage panels 121 with different positioning grooves can be replaced according to the shape of the carried items. By observing whether each positioning groove is empty, the user can also quickly determine whether the corresponding item has been returned or whether there is any missing item.

[0037] During disaster relief, accident response, or temporary on-site command, some supporting items can directly affect the normal use of the terminal. For example, handheld microphones or headsets used in high-noise environments are related to on-site voice communication; backup batteries used when external power is interrupted or the operation lasts for a long time are related to the continuous operation of the terminal; and when the terminal needs to connect to on-site camera equipment, detection equipment, or communication equipment, the corresponding connection cables are related to whether the external equipment can be connected in a timely manner.

[0038] If the aforementioned items are packed separately from the terminal in different bags, on-site personnel will need to simultaneously handle and manage multiple individual packages. During rapid transfers, vehicle changes, or on-site deployment, situations may easily arise such as items being left behind, lost, unclear retrieval locations, or time-consuming searches. Especially in emergency situations, the inability to locate the supporting items in a timely manner may delay the deployment of the terminal, power supply, or the connection of external equipment.

[0039] Emergency supplies 3, used in conjunction with the terminal, are centrally located within storage layer 12 and secured individually using positioning grooves, allowing these items to be carried along with the terminal. When storage layer 12 is opened, each item remains in its designated position, enabling users to retrieve them directly without having to search through multiple bags.

[0040] like Figures 1 to 5 As shown, the housing 1 is also equipped with a locking assembly 2. The locking assembly 2 includes a latch 21, a combination lock 22, and a locking pin 23. The latch 21 and the locking pin 23 cooperate to prevent the display screen 111 from opening relative to the terminal operation layer 11; the combination lock 22 is located between the terminal operation layer 11 and the housing 1 to prevent the terminal operation layer 11 from opening relative to the housing 1. Thus, the opening of the display screen 111 and the opening of the storage layer 12 are controlled by different locking structures.

[0041] The free end of the display screen 111 is provided with a latch 21, which is rotatably mounted on the display screen 111 via a pivot 211 and can rotate between a latched position and a released position. The latch 21 is provided with a slot 212. When the display screen 111 is retracted towards the operation panel 112, the latch 21 contacts the corresponding edge of the terminal operation layer 11; when the latch 21 is pressed or rotated further, the latch 21 undergoes elastic deformation, causing the corresponding edge of the terminal operation layer 11 to enter the slot 212.

[0042] After the latch 21 returns to its original shape, the slot 212 restricts the corresponding edge of the terminal operation layer 11 to prevent the free end of the display screen 111 from flipping upward. When it is necessary to release the connection between the display screen 111 and the terminal operation layer 11, the latch 21 rotates around the pivot 211 in the release direction, causing the slot 212 to disengage from the corresponding edge of the terminal operation layer 11.

[0043] like Figures 2 to 4 As shown, the free end of the display screen 111 is fixed with a fixed shaft 235, and the locking pin 23 includes a sleeve 231 that is slidably sleeved on the fixed shaft 235. The sleeve 231 is provided with a stop seat 234, and the terminal operation layer 11 is provided with a fixed seat 24 corresponding to the sleeve 231. The fixed seat 24 is provided with a pin hole for the sleeve 231 to pass through.

[0044] The ferrule 231 can move along the fixed shaft 235 and is inserted into the pin hole of the fixed seat 24 in the locked position and out of the pin hole in the unlocked position. After the ferrule 231 is inserted into the pin hole, it blocks the displacement required for the buckle 21 to rotate or unfasten, thereby limiting the buckle 21 from rotating to the released position.

[0045] A spring 233 is sleeved on the fixed shaft 235. One end of the spring 233 abuts against the stop seat 234 and pushes the stop seat 234 and the sleeve 231 toward the fixed seat 24, so that the sleeve 231 tends to be inserted into the pin hole when there is no external force.

[0046] A stop plate 232 is also provided on the fixed shaft 235. The stop plate 232 is located on the side of the ferrule 231 away from the stop seat 234, and is used to restrict the ferrule 231 from continuing to move along the fixed shaft 235 and prevent the ferrule 231 from disengaging from the fixed shaft 235. The stop seat 234 is provided with an actuating groove 2341.

[0047] When the lock needs to be released, the user moves the stop seat 234 and the retaining sleeve 231 by turning the slot 2341 to overcome the elastic force of the spring 233, causing the retaining sleeve 231 to exit the pin hole on the fixing seat 24; then, the buckle 21 is rotated to separate the slot 212 from the corresponding edge of the terminal operation layer 11, so that the display screen 111 can be flipped open. After the external force is released, the retaining sleeve 231 can return to the fixing seat 24 under the action of the spring 233.

[0048] A combination lock 22 is located at the junction of the terminal operation layer 11 and the housing 1. After the terminal operation layer 11 is closed, the locking part of the combination lock 22 connects with the mating part on the housing 1, thereby preventing the terminal operation layer 11 from rotating relative to the housing 1. One or more combination locks 22 can be provided; when multiple combination locks 22 are provided, they can be arranged at intervals along the free edge of the terminal operation layer 11 to ensure that the force is more evenly distributed after the terminal operation layer 11 is closed.

[0049] When the combination lock 22 is locked, the terminal operation layer 11 cannot be flipped up as a whole, but this does not affect the display screen 111 from being opened independently relative to the terminal operation layer 11. After the combination lock 22 is released, the terminal operation layer 11 can drive the operation panel 112, the electronic control component 113, and the partition 114 to flip together. Thus, when only the terminal function is used, there is no need to expose the storage layer 12, and when it is necessary to retrieve items, the storage layer 12 can be directly exposed by flipping the terminal operation layer 11 as a whole.

[0050] When the device is in a carrying or transporting state, the terminal operation layer 11 is closed and fixed to the housing 1 by the combination lock 22. The display screen 111 is folded up and covers the operation panel 112. The buckle 21 is fastened to the terminal operation layer 11 through the slot 212, and the locking pin 23 is locked under the action of the spring 233. The emergency supplies 3 in the storage layer 12 are embedded in the positioning groove of the storage plate 121, and the partition 114 separates the emergency supplies 3 from the electronic control components 113.

[0051] Upon arrival at the site, if only the display and operation functions of the terminal are needed, the user does not need to unlock the combination lock 22. Simply move the stop 234 to disengage the card sleeve 231 from the fixing seat 24, then rotate the buckle 21 and flip up the display screen 111 to reveal the operation panel 112. After activating the electronic control component 113, the user can view information, communicate, input commands, or process on-site data through the display screen 111 and the operation panel 112. At this time, the terminal operation layer 11 remains locked to the housing 1, and the storage layer 12 is closed.

[0052] When you need to access the emergency item 3 on the storage panel 121, first fold the display screen 111 or keep it in a position that does not obstruct the flipping of the terminal operation layer 11; then unlock the combination lock 22, flip the terminal operation layer 11 open, and expose the storage layer 12 and the storage panel 121. After taking out the required item, reset the terminal operation layer 11 and lock it again with the combination lock 22, and you can continue to use the display screen 111 and the operation panel 112.

[0053] After use, the emergency item 3 can be placed back into the corresponding positioning groove. Check the position of the positioning groove to see if the item is complete. Then close the terminal operation layer 11 and lock the combination lock 22. Then fold the display screen 111 so that the buckle 21 is fastened to the terminal operation layer 11, and the card sleeve 231 is re-entered into the pin hole of the fixing seat 24 under the action of the spring 233, thereby restoring the device to its carrying state.

[0054] With the above structure, the display screen 111 can be independently flipped to meet the daily operation needs of the terminal, and the terminal operation layer 11 can be opened as a whole to expose the storage layer 12 when needed. The operation area and the item storage area are stacked along the thickness direction of the box 1, and the electronic control components 113 and emergency items 3 are separated by a partition 114; the buckle 21, the locking pin 23 and the combination lock 22 respectively restrict the display screen 111 and the terminal operation layer 11, so that the device can maintain a portable box shape while taking into account the protection of the terminal operation, the centralized carrying of supporting items and the handling state.

[0055] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
