Description

Technical Field

[0001] The invention belongs to the technical field of testing equipment, and in particular relates to a single-person portable universal testing device. Background Art

[0002] Aircraft external products need to undergo functional performance tests before routine technical maintenance and use to ensure functional integrity and mission success rate. Testing work generally requires the use of external testing equipment. Existing testing equipment is generally dedicated or general equipment consisting of multiple 10U or 12U shock-absorbing chassis stacked together. It is large and bulky, difficult to pack and transport, and takes a long time to deploy and withdraw. It cannot meet the needs of rapid and mobile testing in the field and in emergencies. In addition, most of the testing equipment in the existing technology is an overall frame splicing, and the functional unit is a shelf structure. It is difficult to work stably or even unable to perform the work under more complex environmental conditions such as high temperature, high humidity, salt spray, sand and dust.

[0003] Therefore, there is a need for a testing device that can meet the needs of field testing, is easy to transport and carry, and can withstand the harsh testing environment of the field. Summary of the invention

[0004] In view of this, in order to solve the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a single-person portable universal testing equipment with a smaller volume and weight, suitable for one person to carry in a single box, and through the coordinated design of sealing, heat dissipation, and vibration isolation technology, it can adapt to more complex usage environments such as high temperature, high humidity, vibration salt spray, sand and dust, and provide reliable and efficient protection for the functional integrity of the object under test.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A single-person portable universal testing device, comprising an outer box, an inner core and a display assembly, wherein a computer, a power supply and a functional board are integrated inside the inner core, the outer box is a trolley case, and the cover and the box body of the outer box are connected by hinges; the inner core is arranged in the box body of the outer box, a human-machine operation interface is arranged on the upper surface of the inner core, the display assembly is arranged on the inner side of the flip-up cover of the outer box, and the inner core and the display assembly are connected in communication;

[0007] The inner core and the outer box body are connected in a floating manner through a vibration isolator, a vibration reduction space is formed between the inner core and the box body, a protective device is arranged in the vibration reduction space, and the protective device includes a buffer pad arranged on the left and right sides of the inner core and a buffer bridge arranged on the bottom plate of the outer box body;

[0008] A heat dissipation duct is formed between the outer box body, the protective device and the inner core. The buffer bridge is located in the heat dissipation duct below the inner core. It protrudes from the bottom plate of the outer box body toward the bottom surface of the inner core and is set with a gap from the bottom surface of the inner core. The front and rear sides of the outer box body are respectively provided with an air inlet and an air outlet, and the air flow is blown out from the air inlet along the heat dissipation duct and the air outlet.

[0009] Furthermore, an electrical interface is provided on the rear side of the outer box body, and the electrical interface and the air outlet are a composite interface. One side of the interface frame is detachably connected to the rear side wall of the outer box body, and the other side is connected to the side wall of the inner core through a flexible telescopic sleeve. The fan mounting plate is fixed on the interface frame to install a fan that promotes the flow of gas in the heat dissipation duct, and the electrical interface on the inner core is arranged in the flexible telescopic sleeve.

[0010] Furthermore, an openable and closable protective component is provided on the outer side of the electrical interface.

[0011] Furthermore, the shell of the inner core includes an outer shell, an upper cover plate and a bottom plate, and the outer shell, the upper cover plate and the bottom plate are assembled to form a closed metal cavity. The shell of the inner core is made of lightweight metal material, and sealing strips are laid at the joints between the outer shell, the upper cover plate and the bottom plate.

[0012] Specifically, the sealing strip is a conductive rubber strip, which is laid around the connection of the outer shell and connected end to end.

[0013] Furthermore, a buffer ring belt is provided along the circumference direction of the outer edge of the upper cover plate, and its width is greater than twice the gap between the inner core upper cover plate and the outer box body. In a static state, the outer edge of the buffer ring belt contacts the inner wall of the outer box body.

[0014] Furthermore, the inner wall of the outer box body is provided with positioning steps to support the buffer ring belt and reduce the gap to improve the air duct effect.

[0015] Furthermore, the buffer pad and the buffer bridge are both made of flexible materials.

[0016] Furthermore, when the device is in a stationary state, the width of the buffer pad is equal to the vibration-damping space between the inner core and the outer box side wall in the stationary state, filling the vibration-damping space between the left and right sides of the inner core and the box side wall.

[0017] Furthermore, when the device is in a stationary state, the height of the buffer bridge is smaller than the height of the gap between the inner core bottom plate and the outer box body, and the top end of the buffer bridge does not interfere with the inner core bottom plate.

[0018] The beneficial effects of the present invention are:

[0021] A flexible protective device is set in the shock-absorbing space between the outer box and the inner core to form a directional air duct, which takes into account both the shock-absorbing space and the heat dissipation channel, guides the ventilation and protects the inner core during the transportation stage;

[0022] A flexible buffer ring is set between the upper cover of the inner core and the outer box. When the equipment is subjected to vibration or impact, the inner core will shift relative to the buffer ring in the horizontal direction. After the vibration and impact, it will reset under the action of the vibration isolator. The buffer ring can prevent the upper cover of the inner core from rigidly contacting the outer box. At the same time, the maximum gap of the entire displacement process is within the coverage of the buffer ring, so that the air duct between the inner core and the outer box remains closed.

[0023] The design of the composite interface enables the air outlet and the electrical interface to adapt to the floating characteristics of the inner core, while isolating the air outlet and the electrical interface to prevent the airflow from directly entering the exhaust fan from the electrical interface, causing the heat dissipation duct to be short-circuited.

[0036] Specific embodiments are given below to further clearly, completely and in detail illustrate the technical solution of the present invention. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0037] Example 1

[0038] A single-person portable universal testing device comprises an outer box 2, an inner core 3 and a display assembly 1, wherein a computer, a power supply and a functional board are integrated inside the inner core 3, the outer box 2 is a trolley case, and a box cover 22 and a box body 21 of the outer box 2 are connected by hinges; the inner core 3 is arranged in the box body 21 of the outer box 2, a human-machine operation interface is arranged on the upper surface of the inner core 3, the display assembly 1 is arranged on the inner side of the flip-up box cover 22 of the outer box 2, and the inner core 3 and the display assembly 1 are connected in communication;

[0039] The inner core 3 is connected to the outer box body 2 through a vibration isolator 14, and a vibration reduction space is formed between the inner core 3 and the box body 21. A protective device is provided in the vibration reduction space, and a directional heat dissipation duct is formed between the outer box body 2, the protective device and the inner core 3, passing through the front end, bottom surface and rear end of the inner core in sequence. An air inlet 18 and an air outlet are respectively provided on the front and rear sides of the outer box body 2, and the air flow is blown out from the air inlet 18 along the heat dissipation duct and out from the air outlet.

[0040] The inner core 3 is fixed by a vibration isolation device to realize a floating interface. When the equipment is towed on the ground by a pull rod or transported by a vehicle, it can absorb vibration and impact energy from the outer shell, protect internal electronic components, and achieve good anti-vibration characteristics. Between the air inlet 18 and the air outlet, the outer box body 2, the protective device and the inner core 3 are used to form a directional heat dissipation duct, and forced air cooling is used for heat dissipation. The design of the heat dissipation duct is characterized by the combined use of shock absorption space and heat dissipation channel, and a ventilation guide design is performed.

[0041] Furthermore, the display assembly 1 is arranged on the upper cover of the box body 21, and the viewing angle can be adjusted within 0 to 120 degrees along with the upper cover. The operation panel is provided with a keyboard, a mouse, an extended USB port, etc., providing a good human-computer interaction interface.

[0042] Furthermore, shock-absorbing parts are provided at the diagonals of the display assembly 1 on the box cover 22 to prevent the display assembly 1 from colliding with the inner core 3 in the closed state.

[0043] Furthermore, the outer box body 2 is made of high-strength, low-density non-metallic material to effectively resist bumps and scratches and protect the inner core 3 from damage. In this embodiment, materials such as carbon fiber, modified PC, and modified PP can be selected.

[0044] The outer box body 2 is equipped with a drawbar and casters to form a drawbar box, which is convenient for transportation.

[0045] Optionally, in this embodiment, three hinges are set to connect the box cover 22 and the box body 21, the middle hinge is a threading hinge 4, and the two sides are combined damping hinges 5. The threading hinge 4 is used to realize the threading connection between the box body 21 and the box cover 22. The appearance is designed with the characteristic shape of the box body 21, and the wiring harness is hidden in the cavity. The overall appearance is beautiful and the reliability is high.

[0046] Furthermore, the shell of the inner core 3 includes an outer shell 32, an upper cover plate 31 and a bottom plate 33, wherein the outer shell 32 is welded as a whole or processed as a whole, and is opened in the upper and lower directions, and is buckled with the upper cover plate 31 and the bottom plate to form a closed metal cavity. Its structural characteristics are good consistency, good integrity, easy sealing, and good maintainability.

[0047] Furthermore, the upper cover 31 is provided with switches, monitoring meters, USB and other standard peripheral interfaces, function buttons, etc., forming a main human-machine interface, which is convenient for observation and operation, conforms to general usage habits, and has good ergonomic characteristics. Rotating handles 311 are designed on both sides of the upper cover 31, which are flush with the panel in the hidden state to keep the panel flat and beautiful. When in use, they are flipped 90 degrees to protrude the panel, which is used to take out the inner core 3 for easy maintenance.

[0048] Furthermore, the shell of the inner core 3 is made of conductive and heat-conductive lightweight metal material, and sealing strips 15 are laid at the joints between the outer shell 32, the upper cover plate 31 and the bottom plate 33 to achieve heat dissipation, salt spray resistance, and electromagnetic shielding performance.

[0049] Specifically, the sealing strip 15 is a conductive rubber strip, which is laid around the connection of the outer shell 32 and is a whole ring or connected in a ring. The laying position should be set on the inner side of the fastener of the outer shell 32 to improve electromagnetic compatibility and sealing, and protect the internal components from working normally in the electromagnetic environment and marine atmosphere environment.

[0050] The inner core 3 is installed in the outer box body 2 via the vibration isolator 14, and the gap between the inner core 3 and the outer box body 2 will change under the action of vibration or impact. Furthermore, a buffer ring belt 11 is provided along the circumference direction on the outer edge of the upper cover plate 31, and the buffer ring belt 11 is limited by the upper cover plate 31 and the pressure plate 7 at the bottom of the upper cover plate. In this embodiment, the width of the buffer ring belt 11 is greater than 2 times the gap between the upper cover plate 31 of the inner core 3 and the outer box body 2 in the static state, and the thickness direction is positioned between the upper cover plate 31 of the inner core 3 and the pressure plate 7 with a gap, and the outer edge of the buffer ring belt 11 is in contact with the inner wall of the outer box body 2 in the static state. When the equipment is subjected to vibration or impact, the inner core 3 will be offset horizontally relative to the buffer ring belt 11, and will be reset under the action of the vibration isolator 14 after the vibration and impact. There is no rigid contact between the upper cover plate 31 of the inner core 3 and the outer box body 2, so no impact will occur. At the same time, the maximum gap of the entire displacement process is within the coverage range of the buffer ring belt 11, so that the air duct between the inner core 3 and the outer box remains closed.

[0051] Furthermore, the inner wall of the box body 21 of the outer box body 2 is provided with a positioning step 6, and the inner core 3 and the buffer ring belt 11 are tightly attached to the step under the action of their own weight. The positioning step 6 positions and flattens the buffer ring belt 11 in the vertical direction to compensate for its flexible bending or wrinkling defects, and at the same time can reduce the gap to improve the air duct effect.

[0052] Furthermore, the inner wall of the inner core 3 is provided with a plurality of blind holes 36 for cooperating with devices that need to be installed through the board, such as connectors, switches, monitoring meters, etc., and an integrated conductive rubber pad 35 is provided between the connecting flange 34 of the device and the inner wall of the inner core 3 to form a seal.

[0053] Furthermore, the outer wall of the inner core 3 is provided with heat dissipation teeth 8, and the gap formed by the heat dissipation teeth is arranged in a manner consistent with the direction of the airflow. The bottom cover plate and the front panel of the inner core 3 are used as the main heat dissipation surfaces for the installation of the main heat-generating components, and the heat dissipation teeth 8 are designed at the corresponding positions to improve the heat exchange efficiency.

[0054] Furthermore, the protective device includes buffer pads 9 arranged on the left and right sides of the inner core 3 and a buffer bridge 10 arranged on the bottom plate 33 of the outer box body 2, and the buffer pads 9 and the buffer bridge 10 are both made of flexible materials.

[0055] Furthermore, the width of the buffer pad 9 is equal to the width of the vibration-damping space between the inner core 3 and the side wall of the outer box body 2 in a stationary state, filling the vibration-damping space between the left and right sides of the inner core 3 and the side wall of the box body 21, forming a buffer while blocking both sides of the air duct (the gap between the left and right sides of the inner core 3 and the outer box body 2), forming a directional air duct (wind flows from the air inlet on the front side of the box body along the bottom surface of the inner core 3 to the outlet on the rear side of the box body, and will not dissipate to the left and right sides, forming a fixed flow direction), concentrating the heat dissipation flow; at the same time, the inner core 3 can be protected during transportation.

[0056] Furthermore, the height of the buffer bridge 10 is smaller than the gap height between the inner core bottom plate 33 and the outer box body 2, thereby reducing the ventilation gap and forcing the airflow to flow through the shell surface of the inner core 3, so that the heat exchange between the airflow and the shell surface is more sufficient; on the other hand, it plays a role in buffering and preventing impact. In a static state, the top of the buffer bridge 10 does not contact the inner core bottom plate 33. When the inner core moves downward due to vibration or impact, it can contact the buffer bridge 10 and compress and deform it. Due to its flexibility, no impact will be generated; at the same time, the design of the heat dissipation teeth 8 is interrupted at the buffer bridge 10, that is, the inner core is not provided with heat dissipation teeth in the corresponding area above the buffer bridge to ensure that the airflow remains unobstructed when passing through.

[0057] Furthermore, an electrical interface 13 is provided at the rear side of the outer box 2. The electrical interface 13 and the air outlet are a composite interface, which is composed of an interface frame, a flexible telescopic sleeve 17, a fan mounting plate, a fan 16 and a locking piece. One side of the interface frame is detachably connected to the rear side wall of the outer box 2, and the other side is connected to the side wall of the inner core 3 through the flexible telescopic sleeve 17. The fan 16 is fixed on the interface frame, and the electrical interface 13 is arranged in the flexible telescopic sleeve 17. The electrical interface 13 and the inner cavity of the outer box 2 are isolated by the flexible telescopic sleeve 17 connecting the inner core 3 and the outer box 2. The floating characteristics of the inner core 3 under vibration conditions are met through the telescopic deformation of the flexible telescopic sleeve 17.

[0058] Furthermore, the composite interface is arranged in a reticle shape, the electrical interface 13 is arranged in the middle, the fan 16 and the mounting plate are arranged on both sides, and the fan 16 and the electrical interface 13 are separated by a flexible telescopic sleeve 17. The dispersed arrangement of the fan 16 is conducive to uniform distribution of the heat dissipation airflow, and at the same time, the flexible telescopic sleeve 17 forms an isolation to prevent the airflow from directly entering the exhaust fan 16 from the position of the electrical interface 13, so that the heat dissipation air duct is short-circuited; and the flexible telescopic sleeve 17 can be telescopically deformed to meet the floating characteristics of the inner core 3 under vibration conditions.

[0059] Furthermore, an openable and closable protective component 12 is provided on the outside of the electrical interface 13, and the protective component 12 includes a rear door panel and a quick lock mechanism; when opened, the rear door panel is freely flipped down to reveal the air outlet and the electrical interface 13; when closed, the quick lock mechanism can be used to quickly open and close the air outlet and the electrical interface 13 to shield and protect the air outlet and the electrical interface 13. It is used to protect the air outlet and the electrical interface 13 from leakage, and has the characteristics of quick opening and locking.

[0060] Example 2

[0061] Compared with the first embodiment, the difference is that in this embodiment, the outer box 2 is formed of carbon fiber composite material with high strength and light weight, and the casters are 2.5-inch polyurethane casters. The pull rod and the lock are made of modified PP material.

[0062] As an option, the present invention selects aluminum alloy as the preferred material for the shell of the inner core 3, which is integrally processed and formed, has good electrical and thermal conductivity, is convenient for heat dissipation and electromagnetic compatibility design, and is the basis for good electromagnetic compatibility and heat dissipation capacity of the inner core 3. The sealing strip 15 of the inner core 3 uses a 1.8mm diameter fluorosilicone rubber strip (aluminum silver-plated), and the vibration isolator 14 uses a wire rope vibration isolator 14.

[0063] Furthermore, the gap sealing material (buffer pad 9 in the protective device) between the left and right sides of the inner core 3 and the outer box body 2 is made of 1 mm thick aviation rubber plate, which is bonded and fixed on the bracket, and then the bracket is installed on the left and right sides of the inner core 3 shell.

[0064] As an option, the flexible telescopic sleeve 17 is made of rubber material with a Shore hardness of 70-80, has sufficient elastic deformation, and has sufficient shape-keeping ability.

[0065] Furthermore, the buffer belt 11 is made of frosted PVC board with a thickness of 1 mm, a smooth surface, and both deformation ability and toughness.

[0066] The above shows and describes the main features, basic principles and advantages of the present invention. The present invention is not limited to the above model, and can be analyzed and calculated for different number of segments and different types of cages; technicians in this industry should understand that the present invention is not limited to the above embodiment, and the above embodiment and description are only to illustrate the principle of the present invention.
