Description

Technical Field

[0001] This utility model relates to the technical field of computer hardware protection, and in particular to a computer control module connection protection device. Background Technology

[0002] Computer control modules are widely used in industrial automation, smart homes, and smart devices. They connect to external sensors, actuators, power supplies, and other devices through interfaces to achieve data transmission and command control. As the core hub of modern intelligent systems, computer control modules have deeply penetrated multiple fields such as industrial automation, smart homes, and smart devices. Computer control modules are connected to high-precision gyroscopes, motor drivers, and battery management systems through dedicated interfaces to ensure efficient data transmission and stable command execution, providing a solid guarantee for automated operation in complex scenarios. Therefore, there is a particular need for a computer control module to connect and protect devices.

[0003] Chinese patent CN218300459U, published on January 13, 2023, discloses a protection device for the connection port of a computer external device. By using side clamps, grippers, and elastic elements, the connection port can be surrounded, reducing dust ingress and preventing poor contact caused by excessive dust accumulation, thus improving connection stability. However, this computer control module connection protection device only shields the core circuit area of ​​the module during use, without completely covering the connection port, line interface, and other critical parts. This easily creates blind spots in the protection of the module's corners and interface gaps. It lacks a targeted electromagnetic shielding design, relying only on the weak shielding ability of the shell material itself. In industrial environments, high-frequency electromagnetic interference generated by motors and frequency converters, and the use of enclosed metal or opaque plastic shells, requires operators to disassemble the shell to observe the status of the module indicator lights or the connection status of the wires. This leads to a high frequency of disassembly and assembly during operation and maintenance, and the connection between the shell and the module is prone to wear due to repeated disassembly and assembly. It also relies on simple gap fit, resulting in weak dust and water protection. Utility Model Content

[0004] The purpose of this utility model is to provide a computer control module connection protection device to solve the problems mentioned in the background art. Existing computer control module connection protection devices only shield the core circuit area of ​​the module during use, failing to completely cover key parts such as connection ports and line interfaces. This easily creates blind spots in the protection of module corners and interface gaps. Furthermore, they lack targeted electromagnetic shielding design, relying solely on the weak shielding capability of the housing material itself. In industrial environments, high-frequency electromagnetic interference generated by motors and frequency converters, coupled with the use of enclosed metal or opaque plastic housings, requires operators to disassemble the housing to observe the module indicator light status or connection wire connection status, leading to high disassembly and assembly frequency during maintenance. The connection between the housing and the module is prone to wear due to repeated disassembly and assembly, relying only on simple gap fit, and exhibiting weak dust and water resistance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a computer control module connection protection device, comprising a computer control module body, a connection port provided on the outer side of the computer control module body, a wire groove formed on the outer side of the computer control module body, an electromagnetic shielding frame fixedly installed on the outer side of the computer control module body, a connection protection component provided on the outer side of the computer control module body, the connection protection component including a connection protection frame, the connection protection frame being disposed on the outer side of the electromagnetic shielding frame, a sliding groove formed on the top of the connection protection frame, a snap-fit ​​groove formed on the inner side of the connection protection frame, a bottom snap-fit ​​groove formed on the outer side of the connection protection frame, and a bottom snap-fit ​​groove formed on the outer side of the connection protection frame. The side opening has a side slot. The top of the connecting protective frame is provided with a top plate protective plate. A slide rail is fixedly installed at the bottom of the top plate protective plate. A connecting plate is fixedly installed at the bottom of the top plate protective plate. A snap-fit ​​post is fixedly installed on the outside of the connecting plate. An overload protection layer is provided at the bottom of the top plate protective plate. A status monitoring sensor is provided at the bottom of the overload protection layer. A fixing seat is fixedly installed on the outside of the top plate protective plate. A rotating shaft is rotatably connected to the outside of the fixing seat. A transparent protective cover is fixedly installed on the outside of the rotating shaft. The outside of the transparent protective cover is provided with anti-slip texture. A bottom snap-fit ​​plate is fixedly installed on the outside of the transparent protective cover. A side snap-fit ​​plate is fixedly installed on the outside of the transparent protective cover.

[0006] Preferably, the slide groove and the slide rail are provided in two identical sets, and the two sets of slide groove and slide rail are compatible with each other.

[0007] Preferably, the snap-fit ​​slots and snap-fit ​​posts are provided in multiple identical sets, and the multiple sets of snap-fit ​​slots and snap-fit ​​posts correspond one-to-one and are compatible.

[0008] Preferably, the bottom slot is adapted to the bottom latching plate, and the side slots and side latching plates are provided with two identical sets, and both sets of the side slots and side latching plates are adapted to each other.

[0009] Preferably, the overload protection layer is tightly fitted to the top plate protection plate, and multiple identical sets of the status monitoring sensors are provided, with the multiple sets of status monitoring sensors not in contact with the computer control module body.

[0010] Preferably, the assembly of the connecting protective frame, the top protective plate, and the transparent protective cover has a cuboid structure, and the computer control module body is located inside the assembly of the connecting protective frame, the top protective plate, and the transparent protective cover.

[0011] Preferably, the electromagnetic shielding frame is tightly fitted to the computer control module body, and the electromagnetic shielding frame has a fence-like structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The computer control module is connected to a protection device. By setting up a connection protection component, the computer control module body is completely wrapped inside. The fence-like electromagnetic shielding frame fits tightly with the module body, which can specifically shield electromagnetic interference around the connection port. The transparent protective cover is precisely matched with the slots of the connection protection frame through the bottom and side snap-fit ​​plates. After closing, it forms a sealed space, which improves the dustproof and waterproof effect. The top plate protection plate is fixed to the protection frame without tools through the sliding cooperation of two sets of sliding grooves and slide rails, and the one-to-one snap-fit ​​of multiple sets of snap-fit ​​slots and snap-fit ​​posts. The installation time is short. The transparent protective cover can be quickly opened and closed through the rotating shaft, which does not affect the daily observation of the module status and facilitates the quick connection of the connection line in an emergency. The overload protection layer is made of flame-retardant insulating material, which can block the spread of arc when the current is abnormal. With the help of sensors to collect parameters such as module temperature, voltage fluctuation, and interface contact resistance in real time, the risk of module damage is greatly reduced. Operators can directly observe the status of the module indicator lights and the connection status of the connection line without removing the protective cover. At the same time, it can reduce the entry of dust into the module. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5This utility model provides a technical solution: a computer control module connection protection device, including a computer control module body 1, a connection port 2 provided on the outer side of the computer control module body 1, a wire groove 3 formed on the outer side of the computer control module body 1, an electromagnetic shielding frame 4 fixedly installed on the outer side of the computer control module body 1, and a connection protection component 5 provided on the outer side of the computer control module body 1; the connection protection component 5 includes a connection protection frame 501, the connection protection frame 501 is disposed on the outer side of the electromagnetic shielding frame 4, and a sliding groove 502 is formed on the top of the connection protection frame 501. The inner side of the frame 501 has a snap-fit ​​groove 503, the outer side of the connecting protective frame 501 has a bottom snap-fit ​​groove 504, the outer side of the connecting protective frame 501 has a side snap-fit ​​groove 505, the top of the connecting protective frame 501 is provided with a top plate protective plate 506, the bottom of the top plate protective plate 506 is fixedly installed with a slide rail 507, the bottom of the top plate protective plate 506 is fixedly installed with a connecting plate 508, the outer side of the connecting plate 508 is fixedly installed with a snap-fit ​​post 509, the bottom of the top plate protective plate 506 is provided with an overload protection layer 510, the bottom of the overload protection layer 510 is provided with a status monitoring sensor 511, and the top plate... A mounting base 512 is fixedly installed on the outer side of the protective plate 506. A rotating shaft 513 is rotatably connected to the outer side of the mounting base 512. A transparent protective cover 514 is fixedly installed on the outer side of the rotating shaft 513. The outer side of the transparent protective cover 514 is provided with anti-slip texture 515. A bottom snap-fit ​​plate 516 and a side snap-fit ​​plate 517 are fixedly installed on the outer side of the transparent protective cover 514. By setting up the connection protection component 5, the computer control module body 1 is completely wrapped inside. The fence-like electromagnetic shielding frame 4 fits tightly with the module body, which can selectively shield the connection ports. 2. To mitigate electromagnetic interference from the surrounding environment, the transparent protective cover 514 precisely adapts to the slots of the connecting protective frame 501 via the bottom snap-fit ​​plate 516 and the side snap-fit ​​plate 517, forming a sealed space after closure, thus improving dust and water resistance. The top plate protective plate 506 slides with the slide rail 507 via two sets of sliding grooves 502, and multiple sets of snap-fit ​​slots 503 correspond one-to-one with the snap-fit ​​posts 509, allowing the top plate to be fixed to the protective frame without tools, resulting in short installation time. The transparent protective cover 514 can be quickly opened and closed via the rotating shaft 513, which does not affect the daily observation of the module status and facilitates quick connection of the connecting line in emergency situations.

[0021] Furthermore, both the slide groove 502 and the slide rail 507 are provided in two identical sets, and the two sets of slide groove 502 and slide rail 507 are compatible. By setting two sets of slide groove 502 and slide rail 507, the top plate is prevented from tilting or getting stuck due to uneven force when a single slide groove 502 slides, ensuring that the top plate always remains horizontal during adjustment. At the same time, the double slide groove 502 structure can disperse the friction during the sliding process, reduce the wear of a single set of slide groove 502, and extend its service life. The precise compatibility of the two sets of slide groove 502 and slide rail 507 can also limit the lateral displacement of the top plate protection plate 506, ensuring that the docking position between the top plate and the connecting protection frame 501 is always accurate, avoiding protective gaps caused by sliding displacement, and further improving the overall sealing performance of the protection.

[0022] Furthermore, multiple sets of the same snap-fit ​​slots 503 and snap-fit ​​posts 509 are provided, and each set of snap-fit ​​slots 503 and snap-fit ​​posts 509 corresponds to and is compatible with the other. By setting multiple sets of snap-fit ​​slots 503 and snap-fit ​​posts 509, excessive local stress caused by single-point snap-fit ​​is avoided, making the connection between the two more secure. Even in a vibration environment, it is not easy to loosen. At the same time, the multiple sets of snap-fit ​​structures can form a redundancy backup. If a set of snap-fit ​​posts 509 or snap-fit ​​slots 503 experiences slight wear, the other sets can still maintain a stable connection, ensuring that the protective structure does not fail. The precise matching of snap-fit ​​posts 509 and snap-fit ​​slots 503 can also achieve quick positioning of the top plate and the protective frame, and fixation can be completed without repeated adjustments, further shortening the installation time.

[0023] Furthermore, the bottom slot 504 is adapted to the bottom latching plate 516, and the side slots 505 and side latching plates 517 are provided in two identical sets, and both sets of side slots 505 and side latching plates 517 are adapted to each other. By setting two sets of side slots 505 and side latching plates 517, the tilting of the protective cover caused by unilateral fixation is avoided, ensuring that the protective cover fits tightly with the connecting protective frame 501 after closing, without any sealing gap. The side latching and bottom latching cooperate to greatly improve the impact resistance of the protective cover. Even if it is hit by external force, it can effectively prevent the protective cover from falling off. The two sets of side latching structures also make it easier for operators to open and close the protective cover from both sides simultaneously, making the operation more labor-saving and avoiding deformation of the protective cover caused by unilateral force.

[0024] Furthermore, the overload protection layer 510 is tightly bonded to the top plate protection plate 506. Multiple sets of status monitoring sensors 511 are provided, and these multiple sets of status monitoring sensors 511 do not contact each other with the computer control module body 1. By setting multiple sets of status monitoring sensors 511 and the computer control module body 1, multiple sensors can collect parameters such as temperature and voltage from different areas of the module, avoiding blind spots caused by single-point monitoring, making the monitoring data more comprehensive and accurate, and enabling timely detection of local abnormal states of the module. The design that the sensors do not contact the module body can avoid electromagnetic interference to the module circuit when the sensors are working, and at the same time prevent damage to the sensors when the module fails, ensuring that both work independently and stably. The tight bonding between the overload protection layer 510 and the top plate can quickly isolate the electric arc generated during overload above the protection layer, preventing the electric arc from spreading to the module body, buying time for sensor monitoring and subsequent protection actions, and further reducing the risk of module damage.

[0025] Furthermore, the assembly of the connecting protective frame 501, the top protective plate 506, and the transparent protective cover 514 has a cuboid structure. The computer control module body 1 is located inside the assembly of the connecting protective frame 501, the top protective plate 506, and the transparent protective cover 514. By setting the connecting protective frame 501, the top protective plate 506, and the transparent protective cover 514, the cuboid structure can completely enclose the module body, avoiding the blind spots of traditional partial protection. Whether it is the front, side, or top of the module, it can be effectively protected. At the same time, the cuboid structure conforms to the shape design of most computer control modules, which can maximize the use of internal space and avoid the inconvenience of installation caused by the excessive size of the protective structure. The design of the transparent protective cover 514 can also protect the module without affecting the operator's observation of the module status, realizing the dual functions of protection and visualization.

[0026] Furthermore, the electromagnetic shielding frame 4 is tightly fitted to the computer control module body 1. The electromagnetic shielding frame 4 has a fence-like structure. By setting the electromagnetic shielding frame 4 and the computer control module body 1, it can be ensured that the electromagnetic shielding frame 4 can fully cover the outside of the module body, especially the area around the connection port 2. It specifically blocks external electromagnetic interference signals from entering the module, avoiding interference that affects the module's signal transmission and normal operation. While ensuring the shielding effect, the fence-like structure can also provide a certain amount of heat dissipation space for the module, avoiding poor heat dissipation caused by closed shielding, ensuring that the module operates within the normal operating temperature range. The fence-like design can also reduce the weight of the shielding frame, avoiding the module installation burden caused by an excessively heavy shielding frame, while reducing material costs.

[0027] Working principle: First, the operator selects the computer control module body 1 to be protected, cleans its outer surface to remove dust, oil, and other impurities, ensuring the mounting surface is flat and clean. The connecting protection frame 501 is then fitted onto the outside of the electromagnetic shielding frame 4. The position of the protection frame is adjusted to ensure a buffer gap is left between the inner side of the protection frame and the outer side of the electromagnetic shielding frame 4 to prevent direct collision during vibration. Two sets of sliding grooves 502 are symmetrically positioned on the top of the connecting protection frame 501. The length of the sliding grooves 502 must match the sliding stroke of the top protection plate 506. The inner side of the sliding grooves 502 must be polished smooth to reduce sliding friction resistance. Simultaneously, multiple sets of equidistant snap-fit ​​grooves 503 are equidistantly distributed on the inner wall of the connecting protection frame 501. The dimensions of the snap-fit ​​grooves 503 must match the dimensions of the subsequent snap-fit ​​posts 50. 9. Precise fit to ensure no looseness after snap-fit: Bottom slots 504 and two sets of symmetrical side slots 505 are respectively made on the bottom and side of the connecting protective frame 501. The depth and width of the slots must match the corresponding snap-fit ​​plate dimensions, completing the structural pre-processing of the connecting protective frame 501. Two sets of symmetrical slide rails 507 are fixedly installed at the bottom of the top protective plate 506 using bolts. The dimensions of the slide rails 507 must be perfectly matched with the slide grooves 502 of the connecting protective frame 501, ensuring smooth sliding within the slide grooves 502. A connecting plate 508 is fixedly installed at the bottom edge of the top protective plate 506. Multiple sets of snap-fit ​​posts 509 are fixedly installed at equal intervals on the outer side of the connecting plate 508. The positions of the snap-fit ​​posts 509 must align with the snap-fit ​​slots 505 of the connecting protective frame 501. 3. In a one-to-one correspondence, an overload protection layer 510 is then tightly attached to the bottom of the top plate protection plate 506 using strong adhesive. At the bottom of the overload protection layer 510, multiple sets of evenly distributed status monitoring sensors 511 are fixedly installed. The sensors must ensure they do not contact the computer control module body 1 and can accurately align with the module's critical monitoring areas. The sensor wiring terminals must be led out through the pre-drilled holes in the top plate protection plate 506 for easy connection to an external control system. A fixing seat 512 is fixedly installed on the outer edge of the top plate protection plate 506. The outer side of the fixing seat 512 is rotatably connected to a rotating shaft 513 via a bearing, ensuring the rotating shaft 513 can rotate flexibly. A transparent protective cover 514 is then fixedly installed on the outer side of the rotating shaft 513 using bolts. The position of the protective cover is adjusted. To ensure the protective cover completely covers the front opening area of ​​the connecting protective frame 501 when closed, a bottom locking plate 516 and two sets of side locking plates 517 are fixedly installed on the bottom and sides of the outer side of the transparent protective cover 514, respectively. The size of the locking plates must be precisely matched with the bottom locking groove 504 and side locking groove 505 of the connecting protective frame 501 to ensure a tight fit after closing. Finally, anti-slip texture 515 is processed on the outer surface of the transparent protective cover 514 to increase hand friction. After completing the assembly of the protective cover, the top plate protective plate 506 with the assembled slide rail 507 and monitoring components is slidably connected to the slide groove 502 of the connecting protective frame 501 through the slide rail 507. The top plate protective plate 506 is pushed to the preset position so that the locking post 509 is fully engaged with the locking groove 503.After securing the top plate to the protective frame, close the transparent protective cover 514. Check that the bottom snap-fit ​​plate 516 and the side snap-fit ​​plate 517 are tightly engaged with their corresponding slots, and that the protective cover is secure and without gaps. Power on and test the status monitoring sensor 511 to observe whether it can normally collect parameters such as module temperature and voltage. Manually open and close the transparent protective cover 514 to test the flexibility of the rotating shaft 513 and the stability of the snap-fit ​​structure. Simulate an electromagnetic interference environment to verify that the electromagnetic shielding frame 4 can effectively shield interference signals, ensuring normal signal transmission at connection port 2, and that the overall protection function meets the design requirements.
