When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0046] Since existing equipment cabinets primarily serve a storage function, integrating computers with these cabinets aims to improve office convenience and efficiency. However, if the cabinets are too close to the seats, the limited space makes it inconvenient to retrieve items, while if they are too far apart, it makes it difficult for the user to operate the computer while seated.

[0047] This invention proposes an equipment cabinet.

[0048] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the equipment cabinet 100 includes: a cabinet body 1, a slide rail 2, and a locking structure 3. The cabinet body 1 is used for installing or placing equipment. The slide rail 2 extends along a first direction and is provided with a plurality of mating parts 21 at intervals along the first direction. The slide rail 2 is installed at the passenger seat of a police vehicle and is used for sliding and detachably installing the cabinet body 1. It is also used for sliding the bottom of the cabinet body 1. The locking structure 3 is installed on the cabinet body 1 and has a limiting part 31. The limiting part 31 is movably arranged at least along a second direction. The limiting part 31 has a locking position and an unlocking position in its active stroke. The limiting part 31 is located in the locking position to cooperate with one of the plurality of mating parts 21, and the limiting part 31 is located in the unlocking position to disengage from the mating part 21, so that the cabinet body 1 can slide along the slide rail 2.

[0049] The technical solution of this invention involves sliding the cabinet 1 onto the slide rail 2. Since the cabinet 1 extends along a first direction, it can slide along that direction. This allows adjustment of the cabinet 1's position, enabling it to be pushed or pulled to move closer or further away when needed. After adjusting the position, in some situations, it is necessary to fix the cabinet 1 to prevent its position from changing. For example, if the equipment cabinet 100 is mounted on a vehicle, its position may change due to inertia during acceleration or deceleration, causing it to move away from the desired location. Therefore, the slide rail 2 is provided with multiple mating parts 21 spaced apart along the first direction. After the cabinet 1 slides to a suitable position, the limiting part 31 is moved to a locking position to engage with the corresponding mating part 21, thus fixing the cabinet 1 and preventing it from moving along the first direction. When the cabinet 1's position needs to be adjusted again, the limiting part 31 is moved to a releasing position, disengaging from the mating part 21, allowing the cabinet 1 to slide along the slide rail 2. Additionally, it's worth mentioning that the equipment cabinet 100 is primarily used (but not limited to) police vehicles 1000. The slide rail 2 is used for fixed installation in the passenger seat position. The slide rail can slide with both the cabinet body 1 and the passenger seat, and both are detachably connected. Therefore, police vehicles 1000 can install corresponding devices on the slide rail 2 as needed. For general vehicles, the passenger seat itself includes the slide rail 2 and the passenger seat. Matching the slide rail 2 with the cabinet body 1 saves development costs during the design and development process.

[0050] In a specific embodiment of the mating part 21 and the limiting part 31, the mating part 21 is configured as a slot 211, which is positioned facing the opening of the cabinet 1 in a first direction. The limiting part 31 is configured as a limiting post 311, which extends along the first direction. The locking position is the position where the limiting post 311 is inserted into the slot 211, and the unlocking position is the position where the limiting post 311 is disengaged from the slot 211. Alternatively, the mating part 21 and the limiting part 31 can also be configured as a snap-fit ​​(a buckle engages with a protrusion). In this embodiment, the mating part 21 and the limiting part 31 are configured as a slot 211 and a limiting post 311 because: the slot 211 is easier to machine on the slide rail 2, and the limiting post 311 is easier to move (the buckle needs to be flipped).

[0051] Considering that the equipment cabinet 100 is used in a police vehicle 1000, the limiting post 311 and the slot 211 are positioned low, and moving the limiting post 311 requires pushing the cabinet 1 by hand, causing the user to squat or bend over to operate with both hands. To allow the user to easily adjust the position of the cabinet 1, in this embodiment, the locking structure 3 includes a connecting rod 32. The connecting rod 32 extends along a first direction and has a connecting end 321 and an operating end 322. The middle part of the connecting rod 32 is rotatably connected to the cabinet 1. The connecting end 321 is fixedly connected to the end of the limiting post 311 away from the slide rail 2. The operating end 322 is located outside the cabinet 1 for the user to apply external force. The connecting end 321 and the operating end 322 of the linkage 32 are similar to the two ends of a seesaw, with the middle part of the linkage 32 acting as the fulcrum. When the passenger steps on the operating end 322, the connecting end 321 rises, and the limiting post 311 connected to the connecting end 321 is pulled out of the slot 211. Since the middle part of the linkage 32 is connected to the cabinet 1, applying a forward component force to the operating end 322 will move the cabinet 1 forward in the first direction. If the passenger steps on the operating end 322, applying a backward component force will use friction to pull the cabinet 1 backward in the first direction. In addition, multiple protrusions or recesses are provided on the operating end 322 to increase the contact effect between the sole of the shoe and the operating end 322, making it easier for the passenger to operate the cabinet 1 to move backward. Therefore, after stepping on the operating end 322, the passenger can control the cabinet 1 to move in the first direction by extending or retracting their leg. The passenger does not need to bend over or squat down, or use their hands. It should be noted that the width of the slot 211 is greater than the width of the limiting post 11, so the limiting post 11 can be smoothly inserted into or removed from the slot 211 when it rotates around the middle of the connecting rod 32.

[0052] After adjustment, the limiting post 311 is in the locked position. To prevent the "seesaw"—connecting rod 32—from deflecting and to ensure that the cabinet 1 remains locked without human intervention, in one embodiment, the connecting rod 32 has an installation channel 323 with an opening in a first direction. The installation channel 323 is located near the operating end 322. The locking structure 3 further includes a first spring 4, a mounting base 5, and a roller 6. The first spring 4 extends vertically and is installed within the installation channel 323, with one end fixedly connected to the connecting rod 32 and the other end extending outside the installation channel 323. The mounting base 5 is fixedly connected to the other end of the first spring 4 located outside the installation channel 323. The roller 6 is installed on the mounting base 5 to abut against the vehicle body. The first spring 4 lifts the operating end 322, keeping the connecting end 321 in a lower position, thereby keeping the limiting post 311 in the locked position. The installation channel 323 serves to limit the first spring 4, preventing the first spring 4 from tilting. The roller 6 connected to the bottom of the first spring 4 facilitates contact with the ground or vehicle body and has a good movement effect. During the movement, there is only a small amount of friction, which is beneficial for passengers to adjust the position of the cabinet 1.

[0053] Please see Figures 2 to 4 To facilitate quick reset of the cabinet 1 after use, a mounting groove 22 extending along a first direction is provided on the slide rail 2. The cabinet 1 has a connecting portion 11 extending into the mounting groove 22. The equipment cabinet 100 also includes a second spring 7. One end of the second spring 7 is fixedly connected to the end of the slide rail 2 away from the locking structure 3, and the other end is fixedly connected to the connecting portion 11. The length of the second spring 7 is approximately half the length of the mounting groove 22 in the first direction. After pressing down the operating end 322, the cabinet 1 automatically returns to the middle position of the slide rail 2 under the action of the second spring 7. In addition, when the cabinet 1 is in the middle position of the slide rail 2, the spring does not deform. Therefore, whether the cabinet 1 is pushed forward or pulled backward along the first direction, the deformation of the second spring 7 will not be particularly large, and the elastic force required to overcome the second spring 7 is small. It will not significantly hinder the adjustment of the cabinet 1's position. On the contrary, when the cabinet 1 moves from both ends of the slide rail 2 towards the middle, the second spring 7 also provides a certain assistance.

[0054] Since the existing equipment cabinet 100 only serves as a cabinet for storage, in order to give it more functions and facilitate user operation, for the equipment cabinet 100 installed in the police vehicle 1000, please refer to [the relevant documentation / reference]. Figure 1The equipment cabinet 100 may further include a display screen 8, a keyboard, a mouse, a printer, etc., allowing police officers to complete some law enforcement tasks inside the vehicle, providing greater convenience. The keyboard and mouse are placed in the first drawer 13 and electrically connected to the display screen 8; the printer is fixedly installed in the second drawer 14 and electrically connected to the display screen 8. The equipment cabinet 100 also includes a storage cavity 15 for storing tools needed for law enforcement. The display screen 8 is placed on the upper side of the cabinet 1 for easy viewing.

[0055] However, during the sliding of the cabinet 1, or during the acceleration or deceleration of the vehicle, the display screen 8 may shake or be knocked over. Therefore, it is necessary to limit or fix the display screen 8 to the cabinet 1. A typical display screen 8 has a base 81, which is relatively thin. On the side of the cabinet 1 opposite to the slide rail 2, two limiting grooves 12 are provided. The limiting grooves 12 extend along a third direction and open along a first direction; the openings of the two limiting grooves 12 are opposite each other in the first direction; the two sides of the base 81 in the first direction are respectively engaged in the two limiting grooves 12. The first direction is the front-to-back direction of the police vehicle 1000, the second direction is the up-and-down direction of the police vehicle 1000, and the third direction is the left-to-right direction of the police vehicle 1000. In addition, the electrical equipment in the equipment cabinet 100 is used during outings, so the equipment cabinet 100 is also equipped with a power supply and an inverter to supply power to the electrical equipment. Furthermore, some electrical equipment operates at 220V, which can be converted by the inverter to ensure normal operation of the equipment. The equipment cabinet 100 is also equipped with a battery and an electronic control device. The battery is electrically connected to the electronic control device and to the power supply via an inverter. The power supply has a first power consumption state and a second power consumption state, which can be switched between. In the first power consumption state, the battery is electrically disconnected from the electronic control device and the power supply, and the power supply delivers its stored electrical energy to the electronic control device through the inverter. In the second power consumption state, the battery delivers electrical energy to the electronic control device and also delivers electrical energy to the power supply through the inverter. The power supply receives and stores the electrical energy from the battery through the inverter. This configuration ensures that the battery supplies power to the power supply, guaranteeing that the power supply is fully charged and further ensuring the stable operation of the electronic control device. In addition, in the second power consumption state, the battery can not only replenish the power supply's charge but also directly supply power to the electronic control device, reducing the reliance on the power supply and thus extending its lifespan.

[0056] This invention also proposes a police vehicle 1000, please refer to [link / reference]. Figure 5 and Figure 6The police vehicle 1000 includes a body, a rear seat 200, and an equipment cabinet 100. The specific structure of the equipment cabinet 100 is as described in the above embodiments. Since the police vehicle 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. Specifically, the police vehicle 1000 includes a body, a rear seat 200, and an equipment cabinet 100; the body has a front passenger position and a rear passenger position opposite each other in a first direction; the equipment cabinet 100 is installed in the front passenger position and faces the rear passenger position, and the cabinet body 1 is slidably arranged along the first direction; the rear seat 200 is installed in the rear passenger position and faces the front passenger position.

[0057] The front passenger seat and the rear seats are connected in the first direction. The equipment cabinet 100 has a retrieval position away from the rear seats and an operation position close to the rear seats during its travel in the first direction. Passengers in the rear seats can adjust the position of the cabinet 1 to reach the operation position for easy viewing of the display screen 8 and operation of the keyboard, mouse, printer, etc. Since the slide rail 2 is installed in the front passenger seat, to make the cabinet closer to the rear seats when it reaches the operation position for passenger observation and operation, the cabinet 1 slides to the operation position so that at least part of the cabinet protrudes from the slide rail in the first direction. Adjusting the position of the cabinet 1 allows for easy access to the storage compartment 15 for retrieving items. To ensure that passengers can comfortably place their feet when the cabinet 1 reaches the operation position, at least part of the side wall of the cabinet 1 closest to the rear seats is inclined away from the rear seats in the direction close to the slide rail 2, creating a clearance space on one side of the cabinet for passenger footing.

[0058] To prevent a person from suddenly leaning forward and hitting the cabinet 1 during braking, a foam layer is provided on the side of the cabinet 1 facing the rear row. The foam layer includes materials such as pearl cotton and foam board.

[0059] Police vehicles primarily serve the basic function of quickly moving officers from one location to another, and only provide basic physical separation for escorting prisoners. However, with the increasing complexity of public security and the ever-growing demands of policing, the functionality and practicality of existing police vehicles are no longer sufficient to meet the diverse needs of modern policing.

[0060] To address the aforementioned technical issues, the interior space of the vehicle is divided into three areas: a first row (containing the driver and front passenger seats), a second row (containing the rear seats), and a third row, arranged sequentially along the length of the vehicle (i.e., the first direction). This layout separates areas with different functions, clearly defining the function of each row. The junction between the third and second rows can be opened or closed. This allows for security during prisoner transport, while opening it for transporting other goods or personnel, enabling switching between multiple functions. The equipment cabinet 100 also houses a host module that interacts with external signals, enabling timely access to external information such as commands from the command center and traffic conditions. Office equipment interacts with the host module, allowing officers to operate the equipment, such as querying case files and filling out reports. This improves the efficiency of officers working inside the vehicle, transforming it not only into a means of transportation but also a mobile office. The escort seats are installed in the third row, providing a secure hold for the prisoner and preventing escape, ensuring safety during the escort process. The equipment cabinet 400 is installed in three rows of areas to centrally store police equipment, making it easy for officers to quickly access and improving law enforcement efficiency.

[0061] In summary, the above technical solutions make the police vehicle 1000 more efficient in performing its duties. During routine patrols, the equipment cabinet 100 can be used for office work; during escort missions, the escort seat and equipment cabinet 400 ensure prisoner safety and equipment availability; during transport, the interchangeable sections of the three rows of equipment enhance flexibility. The electronic control system improves information technology, enabling officers to obtain and process information promptly, thus enhancing the accuracy and timeliness of law enforcement. The escort seat and equipment cabinet 400 make escorts more standardized and safer, improving the quality and image of law enforcement. Expanding the functionality of the police vehicle 1000 meets the needs of different police operations.

[0062] Furthermore, it is worth mentioning that the equipment cabinet 100, escort seat, and equipment cabinet 400 in this invention all adopt a modular design, which facilitates installation and maintenance, and can be flexibly adjusted and configured on the vehicle body according to actual needs.

[0063] Specifically, the equipment cabinet 400 and the escort chair 300 are arranged side-by-side in a three-row area along a third direction. Connecting plates with multiple connecting holes are installed within this area. A first fixing component is located at the bottom of the escort chair 300, and a second fixing component is located at the bottom of the equipment cabinet 400. These components connect to the first and second fixing components via the connecting holes. By adding connecting plates, drilling holes in the vehicle body is avoided, thus preventing any impact on the vehicle's structural strength. The second fixing component has the same fixing structure as the first fixing component.

[0064] The escort chair 300 can be used for transporting prisoners or replaced with a regular seat for police officers. The equipment cabinet 400 is used to store items. Both the escort chair 300 and the equipment cabinet 400 use the same mounting structure on the connecting plate. The connecting plate is specifically designed for mounting the escort chair 300 and the equipment cabinet 400. The spacing between adjacent connecting holes on the connecting plate is determined by the structure of the mounting structure. The first and second fixing components use the same fixing structure, ensuring that the hole spacing on the connecting plate is uniform. Users can freely adjust the installation position of the escort chair 300 and the equipment cabinet 400 according to their location requirements. The first and second fixing components can consist of multiple bolts with identical spacing, matching the spacing between the connecting holes.

[0065] The bottom of the escort chair 300 and equipment cabinet 400 may have other structures due to requirements, making it impossible for the escort chair 300 and equipment cabinet 400 to be stably placed on the connecting plate. Therefore, a fixing bracket is designed to ensure that the escort chair 300 and equipment cabinet 400 can be stably placed on the connecting plate. The fixing bracket can be set as an L-shaped bent support. Multiple identical fixing brackets ensure that the escort chair 300 and equipment cabinet 400 are stably placed on the connecting plate. Mounting holes corresponding to the connecting holes are opened on the fixing bracket. The fixing nut can be fixed on the back of the connecting plate. The bolt only needs to pass through the connecting hole and the mounting hole and be screwed into the fixing nut to complete the installation. The fixing nut can be movable. After the bolt passes through the connecting hole and the mounting hole, the fixing nut is used to fix the bolt to complete the installation.

[0066] The number of police officers and equipment required varies depending on the number of prisoners being transported. Different quantities of equipment necessitate storage in different sized equipment cabinets 400. Therefore, the number of equipment cabinets 400 needs to be adjusted according to the vehicle type and the number of police officers. Specifically, in this embodiment of the invention, the equipment cabinet 400 includes a first housing and at least one second housing. The bottom of the first housing is provided with a first fixing component to connect to a connecting plate. The bottom of the second housing is provided with an installation structure that inserts into the first housing to connect the first housing and the second housing. The equipment cabinet 400 can be disassembled into a first housing and an appropriate number of second housings. The first housing is fixed to the connecting plate. The number of second housings is determined by the amount of equipment to be stored. The second housings are fixed to the first housing or other second housings via the installation structure. Furthermore, the second housings can be disassembled at any time to reduce the size of the equipment cabinet 400 for use with smaller vehicle types.

[0067] The purpose of the mounting structure is to connect two boxes while allowing them to be separated at any time. Various structural forms are suitable. In this embodiment, the top of the first box has multiple connecting grooves, and the outer periphery of the first box has multiple mounting holes. The mounting structure includes multiple mounting plates, multiple second bolts, and multiple mounting nuts. Multiple mounting plates protrude from the bottom of the second box and are inserted into the connecting grooves. Limiting holes are provided on the sides of the mounting plates, corresponding one-to-one with the mounting holes. Multiple second bolts are respectively inserted into each mounting hole and pass through the corresponding limiting holes. The threaded ends of the second bolts extend to the outside of the mounting holes. Multiple mounting nuts are threadedly connected to the threaded ends of each bolt to prevent the second bolts from disengaging from the mounting holes.

[0068] After the first housing is fixed to the connecting plate by the fixing structure, the mounting plate at the bottom of the second housing is aligned with the corresponding connecting groove on the first housing and inserted to complete the initial positioning. Then, the second bolt is inserted into the mounting hole on the first housing and passes through the limiting hole through the mounting plate. The second bolt is then fixed with the mounting nut. After each mounting plate is fixed with the second bolt and the mounting nut, the connection between the first housing and the second housing is completed. The installed second housing is also installed in the same way as other second housings.

[0069] The connection between the two enclosures is very stable through multiple mounting plates and second bolts, which can withstand large loads and vibrations, ensuring the stability of the overall structure. The installation process is easy to operate and facilitates later maintenance and repair. If it is necessary to replace or repair a certain enclosure, it can be easily disassembled and reinstalled.

[0070] Cars inevitably experience bumps during driving. To prevent items inside the equipment cabinet 400 from colliding with each other, especially metal and plastic items which are prone to damage, it's necessary to store different items in different spaces. Specifically, in the technical solution of this invention, the first cabinet has multiple slots spaced apart, and insert plates are inserted into these slots. These insert plates are used to divide the internal space of the first cabinet. The insert plates divide the interior of the first cabinet into different spaces, each space holding different items according to its size. The insert plates prevent collisions between different items. The size of each space can be adjusted by varying the number of slots between two insert plates, thus changing the size of each space.

[0071] In the interior layout of the vehicle, the escort chair 300 and the equipment cabinet 400 are arranged side-by-side along the left-right direction in the three rows of the vehicle. The back panel of the escort chair 300 and the rear of the equipment cabinet 400 both face the isolation net, and the openings of both the escort chair 300 and the equipment cabinet 400 face the rear door of the vehicle. By restricting the orientation of the escort chair 300 and the equipment cabinet 400, the doors of the escort chair 300 and the equipment cabinet 400 are positioned facing the vehicle door, facilitating police officers to escort prisoners onto the escort chair 300 or to retrieve equipment from the equipment cabinet 400.
