Description

Technical Field

[0001] This utility model relates to the field of intelligent computing terminals, specifically an edge intelligent computing terminal used for fire protection in charging stations. Background Technology

[0002] Intelligent computing terminals can be applied to the safety supervision and intelligent operation and maintenance of new energy vehicle charging stations, aiming to solve core pain points in station operation such as high real-time safety risks, low efficiency of manual monitoring, and delayed handling of abnormal events. Deployed at the edge of the station, they directly analyze camera video streams in real time, accurately identifying key abnormal events such as flames, smoke, people falling, vehicles hitting gate barriers, fire extinguisher displacement, vehicle collisions, and special vehicles (such as fire trucks and ambulances), thereby realizing the transformation from passive monitoring to proactive early warning.

[0003] In charging station applications, edge intelligent computing terminals are typically deployed near cameras to perform local real-time intelligent analysis of video streams and other sensor data to support fire safety functions such as fire identification and abnormal behavior detection. Although the casings of these terminals are generally made of metal and designed to meet IP65 or higher waterproof and dustproof requirements to adapt to complex outdoor environments, their hardware interfaces (such as power interfaces, network interfaces, serial ports, etc.) are mostly made of non-metallic materials (such as engineering plastics or rubber seals). In the event of extreme accidents such as fires, flammable and explosive materials such as batteries in the charging station may release a large amount of high-temperature sparks or heat radiation in a short period of time, causing these non-metallic interface components to deform, melt, or even fail due to heat.

[0004] In actual operation and maintenance, if the overall structure of the terminal is not severely damaged, and only the interface module is damaged, theoretically, it can be quickly repaired by replacing the hardware interface, thereby reducing equipment replacement costs and shortening recovery time. However, existing edge intelligent computing terminals generally have a problem with the interface being highly integrated with the internal motherboard, shielding shell, and sealing mechanism in their structural design. Disassembly requires removing a large number of fixing screws, cables, and sealing strips one by one, which is cumbersome and can easily damage the original sealing integrity. Even if the replacement is completed, it is difficult to ensure that the reassembled terminal can still maintain the original waterproof and dustproof rating, thus affecting its long-term reliable operation in the harsh environment of charging stations.

[0005] To address the aforementioned issues, there is an urgent need to propose an edge intelligent computing terminal for fire protection in charging stations. Utility Model Content

[0006] To address the aforementioned problems in the existing technology, this utility model provides an edge intelligent computing terminal for fire protection in charging stations.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] This utility model discloses an edge intelligent computing terminal for fire protection in charging stations, comprising a terminal housing and an independent interface module. The independent interface module is provided with several interfaces for connecting to an external plug and several metal contacts for connecting to the internal circuitry of the terminal housing. The terminal housing is provided with a sealing and locking component, and the independent interface module is provided with an engagement structure that cooperates with the sealing and locking component. The independent interface module is installed on the terminal housing so that the sealing and locking component and the engagement structure form a sealed connection.

[0009] As a further embodiment of this utility model, the terminal housing is recessed to provide an installation groove for installing the independent interface module, and the sealing and locking component is disposed in the installation groove.

[0010] As a further embodiment of this utility model, the sealing and locking assembly includes a locking mechanism, which includes a locking rod and a button. The button is elastically telescopically disposed on the terminal housing, and one end of the button forms an upward inclined surface inside the terminal housing. The locking rod is provided with an inclined groove. The inclined surface of the button slides away from and contacts the inclined groove to control the locking rod to lock and unlock the engagement structure.

[0011] As a further embodiment of this utility model, the interlocking structure forms an arc-shaped groove on the side of the independent interface module facing the locking mechanism, and the locking rod and the side of the arc-shaped groove are arc surfaces.

[0012] As a further embodiment of this utility model, the sealing and locking assembly further includes a sealing mechanism, which includes a sealing plate with a concave structure. The sealing plate is slidably disposed in the mounting groove. After the independent interface module is installed, the sealing plate surrounds and wraps around the three sides of the independent interface module other than the arc-shaped groove. The surface of the sealing plate is made of a flexible sealing material.

[0013] As a further embodiment of this utility model, the sealing mechanism further includes a return spring, which is disposed between the sealing plate and the terminal housing.

[0014] As a further embodiment of this utility model, a plurality of interfaces of the independent interface module are disposed on the outer surface of the independent interface module, a plurality of metal contacts are disposed on the top of the independent interface module, and the plurality of metal contacts are in contact with and electrically connected to metal contacts at corresponding positions inside the terminal housing.

[0015] As a further embodiment of this utility model, one side of several interfaces of the terminal housing and the independent interface module are made of metal.

[0016] The beneficial effects of this invention are as follows: By designing the interface portion as a modular, easily detachable part, the edge intelligent computing terminal is divided into a main terminal housing and easily detachable independent interface modules. Several interfaces of the independent interface modules are located on their outer surface, and several metal contacts are located on their top. These metal contacts contact and electrically connect with corresponding metal contacts inside the terminal housing. The interfaces on the independent interface modules are used to connect to external connectors, while the metal contacts are used to electrically connect with the internal circuitry of the terminal housing. During installation, the independent interface modules are inserted into the terminal housing, allowing the metal contacts on the independent interface modules to electrically connect with the metal contacts on the terminal housing for signal transmission. When the independent interface modules are damaged, they can be disassembled and replaced individually, ensuring continued use of the edge intelligent computing terminal. Furthermore, both the terminal housing and one side of the interfaces on the independent interface modules are made of metal, preventing burns and damage in high-temperature environments within a short time.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] like Figures 1-3As shown, the present invention discloses an edge intelligent computing terminal for fire protection in charging stations, comprising a terminal housing 1 and an independent interface module 2. The independent interface module 2 is provided with several interfaces for connecting to an external plug and several metal contacts 8 for connecting to the internal circuit of the terminal housing 1. The terminal housing 1 is provided with a sealing locking component, and the independent interface module 2 is provided with an interlocking structure that cooperates with the sealing locking component. The independent interface module 2 is installed on the terminal housing 1 so that the sealing locking component and the interlocking structure form a sealed connection.

[0024] In charging station applications, during extreme accidents such as fires, flammable and explosive materials like batteries can release large amounts of high-temperature sparks or heat radiation in a short time, causing non-metallic interface components to deform, melt, or even fail due to heat. If the overall structure of the intelligent computing terminal is not severely damaged, and only the interface module is damaged, theoretically, it can be quickly repaired by replacing the hardware interface, thus reducing equipment replacement costs and shortening recovery time. However, existing edge intelligent computing terminals generally suffer from a high degree of integration between the interface and the internal motherboard, shielding shell, and sealing mechanism. Disassembly requires removing numerous fixing screws, cables, and sealing strips one by one, a cumbersome operation that easily damages the original sealing integrity. Even after replacement, it is difficult to ensure that the reassembled terminal will maintain its original waterproof and dustproof rating, thus affecting its long-term reliable operation in the harsh environment of charging stations.

[0025] Therefore, by designing the interface section as a modular, easily detachable part, the edge intelligent computing terminal is divided into a main terminal housing 1 and easily detachable independent interface modules 2. Several interfaces of the independent interface module 2 are located on its outer surface, and several metal contacts 8 are located on its top. These metal contacts 8 contact and electrically connect with corresponding metal contacts 8 inside the terminal housing 1. The interfaces on the independent interface module 2 are used to connect to external connectors, while the metal contacts 8 are used to electrically connect with the internal circuitry of the terminal housing 1. During installation, the independent interface module 2 is inserted into the terminal housing 1, allowing the metal contacts 8 on the independent interface module 2 to electrically connect with the metal contacts 8 on the terminal housing 1 for signal transmission. When the independent interface module 2 is damaged, it can be disassembled and replaced, ensuring continued use of the edge intelligent computing terminal. Furthermore, both the terminal housing 1 and the interfaces of the independent interface module 2 are made of metal, preventing them from being burned or damaged in a short time in high-temperature environments.

[0026] As a further embodiment of this utility model, a mounting groove 4 for installing an independent interface module 2 is recessed in the terminal housing 1, and a sealing and locking assembly is disposed within the mounting groove 4. The sealing and locking assembly includes a locking mechanism, which includes a locking rod 7 and a button 3. The button 3 is elastically telescopically disposed on the terminal housing 1, and one end of the button 3 forms an upward inclined surface inside the terminal housing 1. The locking rod 7 is provided with a sloping groove. The slidable separation and contact between the inclined surface and the sloping groove of the button 3 are used to control the locking and unlocking of the locking rod 7 on the engagement structure. The engagement structure forms an arc-shaped groove 6 on the side of the independent interface module 2 facing the locking mechanism, and the locking side of the locking rod 7 and the arc-shaped groove 6 is an arc surface.

[0027] Specifically, both the locking lever 7 and the button 3 are equipped with springs. The spring on the locking lever 7 pushes it downwards, while the spring on the button 3 pushes it outwards from the terminal housing 1. After the independent interface module 2 is installed in the mounting slot 4 of the terminal housing 1, the spring on the locking lever 7 pushes it against the arc-shaped groove 6 on the independent interface module 2, preventing it from falling off. When it is necessary to disassemble the independent interface module 2, the button 3 is pressed, causing the inclined surface at the front end of the button 3 to push the inclined groove on the locking lever 7. Through the relative sliding of the inclined surface and the inclined groove, the locking lever 7 overcomes the spring force and rises, separating the bottom of the locking lever 7 from the arc-shaped groove 6, allowing the independent interface module 2 to be removed from the mounting slot 4.

[0028] As a further embodiment of this utility model, the sealing locking assembly also includes a sealing mechanism, which includes a sealing plate 5 with a concave structure. The sealing plate 5 is slidably disposed in the mounting groove 4. After the independent interface module 2 is installed, the sealing plate 5 surrounds the three sides of the independent interface module 2 other than the arc-shaped groove 6. The surface of the sealing plate 5 is made of a flexible sealing material. The sealing mechanism also includes a reset spring, which is disposed between the sealing plate 5 and the terminal housing 1.

[0029] Specifically, after the independent interface module 2 is installed, the sealing plate 5 adheres to the bottom and two sides of the independent interface module 2 on three sides. Because the surface of the sealing plate 5 is made of a flexible sealing material, it ensures a good seal and provides dust and water protection. Since a return spring is located at the rear end of the sealing plate 5, and the front end of the independent interface module 2 forms a stepped structure, the return spring provides a pushing force to the sealing plate 5, causing it to abut against the stepped structure on the independent interface module 2. During installation, pushing the independent interface module 2 overcomes the spring force of the return spring, ensuring a tight seal between the independent interface module 2 and the sealing plate 5. When the arc-shaped groove 6 passes the locking rod 7, the locking rod 7 engages within the arc-shaped groove 6, creating a locking effect. To disassemble the independent interface module 2, simply press button 3; the locking rod 7 separates from the arc-shaped groove 6, and the return spring pushes the sealing plate 5, pushing the independent interface module 2 out of the mounting slot 4, allowing for quick disassembly.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
