Description

Technical Field

[0001] This application relates to the field of control module structure design, and particularly to a mechanism that can infinitely add expansion modules. Background Art

[0002] As a core component in industrial automation and intelligent devices, the terminal control module has developed rapidly in recent years. It plays a crucial role in data acquisition, instruction parsing, device driving, and system coordination, greatly improving the efficiency and intelligent level of industrial production. With the continuous progress of technology, the application scenarios of the terminal control module are becoming increasingly extensive, and its design and functions have gradually become the focus of the industry. However, due to the diverse functional requirements of different application scenarios, how to achieve modular design to meet diverse needs has become an important research direction.

[0003] In the prior art, in order to meet different functional requirements, a design method with preset interfaces is usually adopted. Specifically, a common means is to connect specific functional modules through fixed interfaces, but this method has poor flexibility and cannot adapt to the needs of multiple function combinations. Another means is to adopt a plug-and-play module design, and the rapid replacement of modules is achieved through standardized mechanical interfaces. However, such designs are often limited to limited function expansion and are difficult to meet the needs of infinite expansion. In addition, there are also solutions to implement specific functional modules through re-molding or customized development, but these methods are not only costly but also have a long development cycle and are difficult to quickly respond to market demands.

[0004] The above-mentioned prior art means generally have a common defect: when adding or replacing functional modules, they are often restricted by the number of interfaces or design, and flexible and infinite function expansion cannot be achieved. This limitation not only increases the user's usage cost but also restricts the application potential of the terminal control module in complex scenarios. Therefore, there is an urgent need for a solution that can break through the limitations of the prior art to achieve infinite expansion of functional modules, so as to better adapt to diverse needs. Summary of the Invention

[0005] In order to overcome the above technical problems, this application provides a mechanism that can infinitely add expansion modules.

[0007] By adopting the above technical solution, the main structure is connected to the expansion module through the expansion interface, the expansion modules are connected to each other through the connection part, and the functional module is fixedly installed on the expansion module through the installation part. It can meet the module expansion of different functional requirements without redevelopment or mold opening, which reduces the use cost and improves the flexibility and adaptability of the system.

[0008] Preferably, the connecting member includes a guide groove provided in the main structure, and a plug-in member provided on the expansion module, the plug-in member corresponds to the guide groove and is plugged into the guide groove to install the expansion module on the main structure.

[0009] By adopting the above technical solution, the cooperation between the guide groove and the connector enables the expansion module to be quickly and accurately installed on the main structure, realizing modular connection, improving the convenience and reliability of the installation of the expansion module, and providing basic support for the subsequent addition of more expansion modules.

[0010] Preferably, a clamping block is provided at the end of the connector away from the expansion module, the guide groove defines a fixing groove corresponding to the clamping block, and when the expansion module is connected to the main structure, the clamping block is located in the fixing groove.

[0011] By adopting the above technical solution, the cooperation between the clamping block and the fixing slot makes the connection between the expansion module and the main structure more stable, effectively preventing the expansion module from loosening or detaching during use, and improving the reliability of the overall structure. At the same time, this design simplifies the installation and removal process of the expansion module, and can achieve quick locking and unlocking without additional tools, which improves the convenience of operation.

[0012] Preferably, the connectors are arranged on both sides of the expansion module, and no less than two connectors are arranged on each side.

[0013] By adopting the above technical solution, the connectors are arranged on both sides of the expansion module and there are no less than two connectors on each side, so that the connection between the expansion module and the main structure is more stable. This design can ensure that the connection part is evenly distributed when subjected to force, avoid the connection failure problem caused by single-point force, and thus improve the stability and reliability of the overall structure.

[0014] Preferably, the side of the guiding groove is connected to the outside, the fixing groove is arranged on the other side of the guiding groove, and the plug-in member is clamped on both sides of the main body structure.

[0015] By adopting the above technical solution, the design that the side of the guiding groove is connected to the outside enables the plug-in member to be conveniently inserted from the outside and complete the clamping operation. At the same time, the disassembly speed is increased during disassembly, further improving the installation convenience. The fixing groove is arranged on the other side of the guiding groove, further ensuring the stability of the plug-in member and preventing it from loosening during use. The design that the plug-in member is clamped on both sides of the main body structure makes the force more uniform, enhances the connection stability, and thus effectively improves the reliability and safety of the connection between the expansion module and the main body structure.

[0016] Preferably, the expansion module further includes a locking mechanism. The locking mechanism includes a locking member and a limiting member. The locking member includes a guiding hole opened on the expansion module and a locking rod. The axis of the guiding hole is parallel to the length direction of the guiding groove, including a first guiding hole close to the main body structure side and a second guiding hole opened on the other side of the expansion module. The locking rod is inserted into the guiding hole and moves in the direction towards or away from the main body structure. The locking member further includes a locking hole opened on the main body structure. The locking hole corresponds to the guiding hole. A locking block is arranged on the side of the locking rod close to the first guiding hole. A moving groove for the locking block to pass through is opened on the side of the locking hole. A cross slot is opened on the end face of the other end of the locking rod. When the locking rod moves towards the locking hole, it moves to the inside of the main body structure through the moving groove. After the locking block passes through the locking hole, it is rotated by a tool abutted against the cross slot, and the locking rod is locked in the locking hole. The limiting member includes a limiting plate arranged on the locking rod and a limiting ring arranged inside the expansion module on one side of the first guiding hole. The limiting ring is sleeved outside the locking rod, and its length is not less than the length of the locking block along the axis direction of the locking rod plus the thickness of the plane where the locking hole is located. The limiting plate is arranged as an annular plate. A limiting tube fixedly connected to the expansion module is arranged on the outside of the limiting plate on one side of the second guiding hole. The limiting ring limits the limiting plate. When the limiting plate moves towards the limiting ring and abuts against the limiting ring, the locking block is pushed into the locking hole. By rotating the locking rod, the expansion module is locked. A second moving groove is opened on the second guiding hole. The second moving groove is for the locking block on the next expansion module to move, and the second guiding hole locks the next expansion module.

[0017] By adopting the above technical solutions, the locking mechanism can achieve a firm connection between the expansion module and the main body structure, and at the same time support the continuous installation and locking of multiple expansion modules. The locking rod moves through the guiding hole and inserts into the locking hole on the main body structure. With the rotation of the locking block, the expansion module is firmly fixed on the main body structure, avoiding loosening caused by vibration or external force. The design of the limiting ring and the limiting plate ensures that the locking rod will not over-expand or contract during operation, effectively preventing locking failure. In addition, the second moving groove on the second guiding hole provides a locking space for the next expansion module, enabling multiple expansion modules to be connected in sequence to form a stable expansion chain, greatly improving the flexibility and expandability of the modular design.

[0018] Preferably, the locking mechanism further includes a reset member, and the reset member includes a reset spring. One end of the reset spring abuts against the limiting plate, and the other end is sleeved outside the limiting ring and abuts against the inner side surface of the expansion module.

[0019] By adopting the above technical solutions, the setting of the reset spring enables the locking rod to automatically reset after disassembly, ensuring that both ends of the locking rod are flush with the two side surfaces of the expansion module, which is convenient for operation during the next installation. At the same time, the design of the reset spring simplifies the reassembly process of the locking mechanism, improves work efficiency and reduces operation complexity.

[0020] Preferably, the limiting member further includes limiting strips arranged circumferentially on the limiting plate and limiting grooves opened on the inner side of the limiting tube. Four limiting strips are evenly arranged along the circumferential direction of the limiting plate, and four corresponding limiting grooves are opened.

[0021] By adopting the above technical solutions, the setting of the limiting strips and the limiting grooves effectively prevents the locking rod from rotating or falling off after being locked, improving the stability of the locking mechanism. Four limiting strips are evenly arranged along the circumferential direction of the limiting plate and cooperate with the limiting grooves correspondingly opened on the inner side of the limiting tube to restrict the circumferential movement of the locking rod, ensuring that the locking rod will not rotate due to external force during the locked state; further improving the reliability of the connection between the expansion module and the main body structure and avoiding connection failure problems caused by loosening of the locking rod.

[0022] Preferably, it further includes an electrical connector. The electrical connector includes a circuit board arranged inside the expansion module and communication holes opened on the expansion module and / or the main body structure. The circuit board is electrically connected to the main body structure through the communication holes; One side of the installation part is provided with an electrical plugging point electrically connected to the circuit board, and the functional module is electrically connected to the main body structure through the installation part.

[0023] By adopting the above technical solution, by arranging a circuit board inside the expansion module and electrically connecting it to the main structure through a communication hole, the stable transmission of signals and power is ensured, supporting the normal operation of multiple functional modules. The electrical plug-in points on the installation part are electrically connected to the circuit board, further ensuring the electrical connectivity between the functional module and the main structure, and improving the reliability of the overall mechanism. Without additional wiring, the installation and maintenance processes are simplified, and the integration and expandability of the system are improved.

Referring to Figure 1 , the mechanism that can infinitely increase expansion module 2 includes main structure 1, expansion module 2 and functional module 3. Among them, main structure 1 and expansion module 2 cooperate with each other through connecting part 21, expansion modules 2 are connected to each other through connecting part 21, and functional module 3 is installed on expansion module 2, realizing flexible expansion of the modules and improving the expandability of the overall structure.

[0032] Referring to Figure 3 , Figure 4 , specifically, expansion module 2 includes connecting part 21 and installation part 22. Connecting piece 211 in connecting part 21 is composed of plug-in part 2112 and clamping block 21121. Plug-in part 2112 can be rectangular or circular column, and clamping block 21121 is arranged at its end.

[0033] Referring to Figure 2 , on one side of main structure 1, expansion interface 11 is opened, and expansion interface 11 includes guide groove 2111 and fixing groove 21111. Guide groove 2111 can be a long strip-shaped groove for guiding the sliding of plug-in part 2112, and fixing groove 21111 is arranged on one side of guide groove 2111 for fixing clamping block 21121. The cooperation relationship between guide groove 2111 and fixing groove 21111 ensures the stable installation of expansion module 2.

[0034] Referring to Figure 3 , Figure 4 , installation part 22 is mainly used for installing functional module 3. A clamping groove is arranged on the upper side of installation part 22, and a buckle connected to the clamping groove is arranged on functional module 3. The buckle structure can adopt elastic plastic material, which is convenient for quick installation and disassembly.

[0035] The locking mechanism 23 includes a locking member 231 and a limiting member 232. The guiding hole 2311 in the locking member 231 consists of a first guiding hole 23111 and a second guiding hole 23112. The first guiding hole 23111 is close to the main body structure 1, and the second guiding hole 23112 is located on the other side of the expansion module 2. A second moving groove 23131 is formed in the second guiding hole 23112 for the locking block 23121 on the next expansion module 2 to move. The second guiding hole 23112 locks the next expansion module 2.

[0036] The axis of the guiding hole 2311 is parallel to the length direction of the guiding groove 2111 to ensure that the locking rod 2312 can move along a predetermined direction. The locking rod 2312 can be made of high-strength steel and its surface is hardened to improve wear resistance and fatigue resistance. The locking block 23121 is arranged on the side of the locking rod 2312 close to the first guiding hole 23111 and is locked after entering the locking hole 2313 through the moving groove 23131. The moving groove 23131 is formed on the side surface of the locking hole 2313 to facilitate the movement of the locking block 23121.

The limiting ring 2322 is sleeved on the outer side of the locking rod 2312 to limit the limiting plate 2321. For example, the limiting plate 2321 can be made of aluminum alloy, which is light and has high strength. The limiting ring 2322 can be made of stainless steel to ensure the reliability of the limitation. The limiting tube 2323 can be made of plastic to reduce weight and cost.

One end of the reset spring 2331 abuts against the limiting plate 2321, and the other end is sleeved on the outer side of the limiting ring 2322 and abuts against the inner side surface of the expansion module 2. The reset spring 2331 can be made of music wire, which has good elasticity and durability. The function of the reset spring 2331 is to automatically reset the locking rod 2312 to the initial position when the expansion module 2 is disassembled, facilitating the next use.

[0039] The limiting strip and the limiting groove are used to prevent the locking rod 2312 from rotating and falling off. Four limiting strips are evenly arranged along the circumferential direction of the limiting plate 2321, and the corresponding limiting grooves are formed on the inner side of the limiting tube 2323. For example, the limiting strip can be made of high-strength steel and its surface is quenched to improve wear resistance. The limiting groove can be made of plastic material to reduce weight and cost. The matching relationship between the limiting strip and the limiting groove ensures the stability and reliability of the locking rod 2312.

[0040] Referring to Figure 3 , the electrical connector 4 includes a circuit board 41 and a communication hole 42. The circuit board 41 is arranged inside the expansion module 2 and is electrically connected to the main body structure 1 through the communication hole 42. For example, the circuit board 41 can be made of FR-4 material, which has good insulation and heat resistance. The communication hole 42 can be made of copper material and its surface is gold-plated to improve conductivity and oxidation resistance. The electrical plug-in point is arranged on one side of the installation part 22 and is electrically connected to the circuit board 41 for realizing the electrical connection of the functional module 3.

[0041] The implementation principle of the mechanism capable of infinitely increasing the expansion module 2 in the embodiment of the present application is as follows: Through the cooperation between the expansion interface 11 on the main body structure 1 and the connection part 21 of the expansion module 2, the installation and expansion of the expansion module 2 are realized. The plug-in part 2112 and the clamping block 21121 in the connection part 21 ensure the stability and reliability of the expansion module 2. The locking mechanism 23 further enhances the connection strength of the expansion module 2 and prevents accidental detachment. The electrical connector 4 realizes the electrical connection between the expansion module 2 and the main body structure 1 to ensure the normal operation of the functional module 3. The overall structure is reasonably designed, easy to operate, can meet the demand of infinitely expanding the functional module 3, and significantly improves the flexibility and adaptability of the terminal control module.
