Description

Technical Field

[0001] This utility model relates to the field of power signal wall box technology, specifically a power signal wall box adapted to a special chassis. Background Technology

[0002] The chassis power signal box is a special box installed on the vehicle chassis to store and manage power and signal lines. It can protect the wiring harness from external damage and ensure the normal operation of the vehicle's electrical system.

[0003] Existing modular shelter interiors primarily focus on the functionality of the power and signal boxes, lacking improvements in ease of operation and maintenance safety. During use, due to the tilted installation between the Mengshi chassis wall and the power and signal boxes, the traditionally designed inner box is tilted downwards when transferring it inside the vehicle. This inconveniences operators and increases maintenance difficulty. This tilted angle also prevents operators from easily viewing the inner box directly, increasing the risk of equipment maintenance issues.

[0004] Therefore, we propose a power signal box adapted to a special chassis to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a power signal box adapted to special chassis, so as to solve the problem mentioned in the background art that the inner box of the existing power signal box is tilted downwards due to the tilt of the special vehicle chassis, which makes it inconvenient to operate and maintain.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A power signal box adapted to a special chassis includes an irregularly shaped box body, which is installed on the wall of the vehicle chassis. The irregularly shaped box body includes a panel for external connection operations within the vehicle cabin and an inner box for internal connection operations within the vehicle cabin. The inner box integrates layered isolation chambers to separate cable channels for navigation, communication, entertainment, and lighting systems. The panel and the inner box are fixedly connected. Signal interfaces are provided on the end of the inner box away from the panel and on the surface of the panel. The signal interfaces of the inner box face inwards from the vehicle cabin, while the signal interfaces of the panel face outwards from the vehicle cabin. When the panel is perpendicular to the horizontal plane, the surface of the inner box on the side closest to the vehicle cabin is inclined and matches the inclination angle of the vehicle chassis wall. After the power box is installed on the vehicle chassis wall, the inclined inner box is perpendicular to the horizontal plane.

[0008] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0009] This utility model's power signal wall box, through improved structural design, allows for convenient operation both inside and outside the vehicle. Specifically, the inner box is designed to tilt at 15° when the panel is perpendicular to the horizontal plane, matching the tilt angle of the vehicle chassis wall. The inner box is mounted on the vehicle chassis using a specially shaped body, ensuring that it remains vertical inside the vehicle cabin after installation. This design significantly improves the ease of operation, reduces inconvenience caused by the tilt angle, and enhances operational safety.

[0010] Furthermore, by designing the power signal box as a split structure, the inner box and the panel are fixedly connected. The signal interface of the inner box faces the interior of the vehicle cabin, while the signal interface of the panel faces the exterior. In addition, the inner box integrates layered isolation chambers to physically separate cable channels of different systems, reducing signal interference and improving signal stability. The panel adopts a modular dustproof and waterproof structure, with replaceable standard interfaces embedded inside. It communicates with the inner box via snap-on connectors, supporting plug-and-play functionality, and allows for quick disassembly and maintenance via quick-release magnetic connection components. These improvements not only enhance operational convenience and maintenance safety but also strengthen the overall reliability and adaptability of the equipment, meeting the needs of special vehicle usage scenarios.

[0016] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0017] Example 1:

[0018] Please see Figure 1-4 The present invention provides the following technical solution:

[0019] A power signal box adapted to a special chassis includes a non-standard box 1, which is mounted on the wall of the vehicle chassis. The non-standard box 1 includes a panel 2 for external connection operations and an inner box 3 for internal connection operations. The inner box 3 integrates layered isolation chambers to separate cable channels for navigation, communication, entertainment, and lighting systems. The panel 2 and the inner box 3 are fixedly connected. Signal interfaces 5 are provided on the end of the inner box 3 away from the panel 2 and on the surface of the panel 2. The signal interfaces 5 of the inner box 3 face inwards from the vehicle cabin, while the signal interfaces 5 of the panel 2 face outwards from the vehicle cabin. When the panel 2 is perpendicular to the horizontal plane, the surface of the inner box 3 closest to the vehicle cabin is inclined and matches the inclination angle of the vehicle chassis wall. After the power box is mounted on the vehicle chassis wall, the inclined inner box 3 is perpendicular to the horizontal plane.

[0020] By combining the split inner box 3 with the panel 2, and utilizing the tilted design of the inner box 3, the signal interface 5 of the inner box 3 is angled to match the vehicle wall, ensuring that the inner box 3 is vertically and horizontally positioned within the vehicle cabin after installation. Layered isolation chambers physically separate navigation, communication, and other signal cables, preventing interference and resolving the issue of tilted operating angles within the vehicle cabin, allowing personnel to view the operating interface directly. Layered cable management improves signal stability; for example, it isolates high-frequency communication lines from power lines, thereby reducing the risk of electromagnetic interference and facilitating troubleshooting.

[0021] Furthermore, when the inner box 3 is perpendicular to the horizontal plane of the panel 2, it is designed to be tilted at an angle of 15°, which matches the tilt angle of the vehicle chassis wall, and an elastic sealing gasket is provided between the side wall of the inner box 3 and the vehicle wall.

[0022] The 15° tilt of the inner box 3 precisely matches the natural angle of the vehicle wall, adapting to some special models, such as the chassis of the Mengshi off-road vehicle; the elastic sealing gasket fills the gap between the inner box 3 and the vehicle wall after compression, and is locked in place with the metal pressure strip, eliminating installation gaps caused by uneven curvature of the vehicle wall and enhancing waterproof and dustproof performance; the optimized tilt angle avoids mechanical stress concentration and extends the life of the box.

[0023] Furthermore, panel 2 adopts a high-precision injection-molded modular dustproof and waterproof structure. A sealed flip cover 7 is set on the surface of panel 2, and a replaceable standard interface is embedded inside. The replaceable standard interface communicates with the inner box 3 through a snap-fit ​​connector. Panel 2 adopts a standard design to be compatible with existing vehicle power signal systems. The inner box 3 is used to connect the vehicle's navigation and communication electrical systems.

[0024] The sealed flip cover 7 prevents water and dust from entering through a labyrinthine sealing groove. The standard interface module communicates with the inner box 3 through a snap-on connector, supporting plug-and-play replacement. The modular interface design is compatible with multiple vehicle interface standards, such as USB or aviation plug, reducing upgrade or maintenance costs.

[0025] Furthermore, the irregular box 1 is composed of a first box 10 and a second box 11. The first box 10 and the second box 11 are attached to each other, and the side of them close to the vehicle wall is combined into a plane, while the side of them away from the vehicle wall is set as a stepped structure 12.

[0026] The joint side of the first housing 10 and the second housing 11 is flat to ensure a tight fit with the vehicle wall. The side of the first housing 10 and the second housing 11 away from the vehicle wall is designed as a stepped structure 12 to prevent the inclined end of the one-piece flat design panel 2 from protruding more, reducing the risk of bumps during driving and protecting the panel 2. The stepped structure 12 away from the vehicle wall can be fixed with cables of different heights by elastic limiting blocks.

[0027] Furthermore, the inner box 3 is connected to the panel 2 by a three-axis positioning bolt. The countersunk hole of the bolt is equipped with a shock-absorbing rubber sleeve, and the end of the bolt is equipped with a self-locking nut.

[0028] The three-axis bolts use countersunk hole rubber sleeves to buffer vibrations, self-locking nuts to prevent loosening, and slide rail spring clips to assist in positioning. This is used to eliminate the impact of vehicle vibrations on the interface connection and improve the stability of power signal transmission.

[0029] Furthermore, a quick-release magnetic connection assembly is used between panel 2 and inner box 3, and the quick-release magnetic connection assembly is controlled by a circuit switch.

[0030] Furthermore, the quick-release magnetic connection assembly includes a permanent magnet and an electromagnet. The permanent magnet is fixed to the panel 2, and the electromagnet is installed in the inner box 3. When powered on, it generates a magnetic force to attract the panel 2. When powered off, the panel 2 can be easily removed.

[0031] When the electromagnet is energized, it forms a strong magnetic attraction with the permanent magnet. After the power is turned off, the magnetic force disappears and it can be disassembled by hand. The intelligent control module interlocks to achieve safe power-off. The interface inside panel 2 can be quickly maintained without tools. The electromagnetic control improves the safety of disassembly and avoids damage to panel 2 and inner box 3.

[0032] Furthermore, the signal interface 5 adopts a three-proof composite structure, with a guide groove at each end of the interface to prevent mis-insertion.

[0033] By uniquely matching the shape of the plug with the guide groove at the interface end, damage to the equipment caused by human error is reduced.

[0034] Furthermore, the irregularly shaped box 1 is made entirely of lightweight carbon fiber reinforced composite material, and the surface of the panel 2 is covered with a scratch-resistant and wear-resistant coating 21.

[0035] The carbon fiber honeycomb structure reduces weight while maintaining strength, and the sound-absorbing sponge filling reduces cable vibration noise; the scratch-resistant coating on panel 2 is sprayed to match the body color.

[0036] Furthermore, a sliding cover 22 is provided at one end of the inner box 3 near the interior of the vehicle compartment, and a protruding plate 23 for pushing and pulling is fixedly connected to the sliding cover 22.

[0037] The sliding cover 22 covers the interface area of ​​the inner box 3 by pushing and pulling through the protruding plate 23. The signal interface 5 can be quickly exposed during operation, and it is dustproof and prevents accidental touch when not in use. The protruding plate 23 is designed to be easy to operate while wearing gloves, which meets the needs of special vehicle use scenarios.

[0038] The working principle of the power signal wall box adapted to special chassis: Through a split design, the inner box 3 is combined with the panel 2. The inner box 3 is installed at an angle to match the tilt angle of the vehicle chassis wall, ensuring that the inner box 3 is perpendicular to the horizontal plane inside the vehicle compartment after installation. The inner box 3 has a layered isolation chamber to separate the cable channels of different systems, reducing interference and improving signal stability. The panel 2 and the inner box 3 are fixedly connected. The signal interface 5 of the panel 2 faces outward from the vehicle compartment for easy external operation, while the signal interface 5 of the inner box 3 faces inward for easy internal connection. The panel 2 adopts a modular dustproof and waterproof structure with a replaceable standard interface embedded inside. It communicates with the inner box 3 through a snap-on connector, achieving plug-and-play functionality. In addition, the wall box uses a quick-release magnetic connection assembly, and the panel 2 can be quickly disassembled and maintained through a circuit-controlled switch. The signal interface 5 adopts a three-proof composite structure with a guide groove to prevent mis-insertion and ensure correct connection. The entire wall box is made of lightweight carbon fiber reinforced composite material. The surface of the panel 2 is covered with a scratch-resistant and wear-resistant coating 21. One end of the inner box 3 is equipped with a sliding cover 22 and a protruding plate 23 for quickly exposing and concealing the signal interface 5 to meet the needs of special vehicle use scenarios.

[0039] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
