[0053] In order for the person skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0054] The present application provides a controller assembly, please refer to Figures 1 to 16 The controller assembly comprises a main plate 10, an inner carrier 20 and an outer carrier 30, the main plate 10 is provided with a first sensing part 11; the main plate 10 is arranged on the inner carrier 20 so that the main plate 10 and the inner carrier 20 are relatively fixed; the inner carrier 20 is arranged on the outer carrier 30, and the outer carrier 30 is provided with a second sensing part 31; the outer carrier 30 is movably arranged relative to the inner carrier 20.

[0055] When the outer carrier 30 and the inner carrier 20 are in the initial matching state, the first sensing part 11 and the second sensing part 31 are matched with each other. By the sensing matching of the first sensing part 11 and the second sensing part 31, the in-place state of the main plate 10 is detected; that is, the in-place state of the main plate 10 is monitored by the first sensing part 11 and the second sensing part 31.

[0056] When the outer carrier 30 starts to move relative to the inner carrier 20, the second sensing part 31 moves away from the first sensing part 11 to trigger a pull-out signal to control the main plate 10 to perform data backup; that is, when the main plate 10 receives the pull-out signal, it starts to perform data backup.

[0057] When the outer carrier 30 moves a first preset distance relative to the inner carrier 20, the outer carrier 30 continues to move and moves together with the inner carrier 20 and the main plate 10, so that the main plate 10 is pulled out. That is, in the process of moving the outer carrier 30 relative to the inner carrier 20 by a first preset distance, the main plate 10 performs data backup.

[0058] Optionally, the data backup of the main plate 10 includes backup of critical data.

[0059] It should be noted that, in the process of the outer carrier 30 continuing to move and moving together with the inner carrier 20 and the main plate 10, not only the main plate 10 is pulled out, but also the outer carrier 30 and the inner carrier 20 are pulled out together.

[0060] In the present application, the controller assembly realizes intelligent monitoring of the in-place state of the main plate and accurate control of the pull-out process through the combined design of the main plate 10, the inner carrier 20 and the outer carrier 30, and the interaction of the first sensing part 11 and the second sensing part 31.

[0061] In the initial matching state, the mutual induction matching of the first induction part 11 and the second induction part 31 constitutes an intelligent detection system, which can monitor the in-place state of the mainboard 10 in real time. This design can issue an early warning at an early stage of the mainboard 10 being pulled out, reminding the user of the operation to be performed and automatically preparing data backup, thereby greatly improving data security and controllability of the operation.

[0062] When the outer carrier 30 starts to move relative to the inner carrier 20, the second induction part 31 gradually moves away from the first induction part 11, and this change is designed to trigger the pull-out signal of the mainboard 10 and automatically start the data backup process. Compared with traditional manual data backup or preset software response, this automatic backup triggering mechanism based on physical proximity change can respond more quickly and accurately to the pull-out operation of the mainboard, avoiding data omission caused by human factors.

[0063] The first preset distance movement between the outer carrier 30 and the inner carrier 20 ensures that the mainboard 10 remains in place before the data backup is completed. Only when the outer carrier 30 moves beyond this preset distance, the mainboard 10 is pulled out together with the inner carrier 20. This design avoids the situation of incomplete data backup or sudden interruption of hardware connection during the backup process, ensuring the continuity and integrity of the data backup process and improving the reliability of the system.

[0064] The pull-out warning and data backup starting mechanism realized through physical design effectively prevents the sudden disconnection of the controller node due to misoperation or accidental incidents, reducing the possibility of data loss. This is particularly important for application scenarios with high requirements for data continuity and integrity, and can significantly improve the security level of data.

[0065] The sliding operation of the outer carrier 30 is intuitive and simple, and the user can complete the pull-out and insertion of the mainboard without complex operation procedures. This friendly design not only improves operation efficiency, but also reduces user confusion and errors during operation, improving overall user experience.

[0066] Through the movable connection design of the inner carrier 20 and the outer carrier 30 and the precise control of the first preset distance, the entire controller assembly can maintain good structural integrity and reliability during repeated pull-out and insertion operations, reducing mechanical wear and failure caused by frequent operation.

[0067] The controller assembly of the present application significantly enhances the monitoring capability of the in-place state of the mainboard through precise induction part matching and orderly pull-out control process, realizes timely and complete data backup, effectively prevents data loss, and also improves the convenience of user operation and the overall robustness of the system.

[0068] In the present application, one of the outer carrier 30 and the inner carrier 20 is provided with the first sliding part 32, and the other is provided with the first sliding groove 21; the first sliding part 32 is slidably arranged in the first sliding groove 21, so that the outer carrier 30 is slidable relative to the inner carrier 20, that is, the outer carrier 30 is pulled and slid relative to the inner carrier 20.

[0069] Optionally, the outer carrier 30 is provided with the first sliding part 32, and the inner carrier 20 is provided with the first sliding groove 21.

[0070] Optionally, the first sliding part 32 and the first sliding groove 21 are both multiple, and the multiple first sliding parts 32 are one-to-one slidably arranged in the multiple first sliding grooves 21; the extension directions of the multiple first sliding grooves 21 are all parallel.

[0071] Optionally, the multiple first sliding parts 32 are uniformly distributed, and the multiple first sliding grooves 21 are uniformly distributed.

[0072] Optionally, the first sliding part 32 is a sliding nail; for example, the first sliding part 32 is a H-shaped nail, that is, the first sliding part 32 is a H-shaped nail pressed by riveting.

[0073] Optionally, the first sliding groove 21 is a strip-shaped hole; for example, the first sliding groove 21 is a waist-shaped hole.

[0074] In the present application, the controller assembly further comprises an acting assembly 40, and the acting assembly 40 comprises an acting piece 41, a first transmission piece 42 and a second transmission piece 43.

[0075] The acting piece 41 is connected with the outer carrier 30, so that the acting piece 41 drives the outer carrier 30 to move. That is, in the process that the outer carrier 30 moves relative to the inner carrier 20 by a first preset distance, the acting piece 41 drives the outer carrier 30 to move; and after the outer carrier 30 moves relative to the inner carrier 20 by the first preset distance, the acting piece 41 drives the outer carrier 30 to continue to move.

[0076] The first transmission piece 42 is connected with the acting piece 41, and the second transmission piece 43 is connected with the first transmission piece 42, so that after the acting piece 41 moves relative to the first transmission piece 42 by a first preset distance, the acting piece 41 drives the first transmission piece 42 to move together. Among them, in the process that the acting piece 41 drives the first transmission piece 42 to move by a fourth preset distance, the first transmission piece 42 drives the second transmission piece 43 to perform a helping pulling action through a cooperation mechanism; after the acting piece 41 drives the first transmission piece 42 to move by the fourth preset distance, the acting piece 41 continues to drive the first transmission piece 42 to move, at this time, the first transmission piece 42 drives the second transmission piece 43 to move together in the same direction; the second transmission piece 43 is connected with the inner carrier 20, so that the second transmission piece 43 drives the inner carrier 20 and the mainboard 10 to move together, and then the mainboard 10 is pulled out.

[0077] That is, after the first transmission member 42 is moved by the action member 41 by the fourth preset distance, the action member 41 continues to move, so that the mainboard 10 is pulled out, and the action assembly 40, the outer carrier 30 and the inner carrier 20 are pulled out together.

[0078] It should be noted that in the process of moving the first transmission member 42 together with the action member 41, the action member 41 also moves the outer carrier 30 together.

[0079] The action member 41 can efficiently transmit the operation force of the user to the outer carrier 30 through the direct connection with the outer carrier 30, and drive the outer carrier 30 to move relative to the inner carrier 20. The linkage design of the first transmission member 42, the action member 41 and the second transmission member 43 ensures that the second transmission member 43 can be triggered accurately during the movement of the action member 41 by the fourth preset distance, so as to realize the smooth pulling out of the mainboard 10. The hierarchical transmission mechanism improves the control accuracy and efficiency of the pulling out process.

[0080] In the process of moving the outer carrier 30 until the mainboard 10 is completely pulled out, the first preset distance allows the timely detection of the in-place state of the mainboard 10 and the start of data backup. The fourth preset distance ensures the pulling out action, and the orderly transmission and pulling out of the action assembly 40 avoid the impact and damage of direct force on the mainboard 10 or other precision components. This design not only protects the hardware components, but also ensures the continuity of the pulling out process and the safety of the operation.

[0081] The hierarchical design of the action member 41 and the operation process simplifies the user operation, and the user does not need to directly control the movement of the mainboard 10 or the inner carrier 20, but only needs to operate the action member 41. This not only makes the pulling out operation more intuitive and simple, but also reduces the operation difficulty and improves the accuracy and satisfaction of the user operation.

[0082] The hierarchical action mechanism of the transmission member can effectively cope with the uncertainty under various operation conditions, such as sudden external force interference or uneven force of the operator. This design can ensure that the pulling out operation of the controller node can be smoothly completed according to the predetermined process even in complex or unfavorable environment, and enhances the reliability and stability of the system.

[0083] The design of the action assembly 40 realizes the intelligent control from the pulling out signal triggering to the actual pulling out of the mainboard 10. Through the cooperation between the accurate preset distance and the transmission member, the data backup and hardware separation are automatically completed without additional manual intervention of the user, which improves the intelligent level of the system.

[0084] The introduction of the action assembly 40 not only optimizes the user operation experience through the hierarchical design of the transmission mechanism, reduces hardware damage, but also significantly enhances the intelligence and reliability of the system, which is of great significance to improve data security and operation reliability.

[0085] In the present application, the action piece 41 is movably arranged relative to the first transmission piece 42 and the outer carrier 30, so that the action piece 41 moves alone relative to the outer carrier 30 by a second preset distance before driving the outer carrier 30 to move.

[0086] That is, the action piece 41 moves relative to the first transmission piece 42 by a third preset distance before driving the first transmission piece 42 to move; the third preset distance is equal to the sum of the second preset distance and the first preset distance.

[0087] In the present application, the action piece 41 is movably arranged relative to the first transmission piece 42 and the outer carrier 30, and can move alone relative to the outer carrier 30 by a second preset distance before directly driving the outer carrier 30 to move.

[0088] The setting of the second preset distance allows the action piece 41 to first move a certain distance without directly affecting the mainboard 10 and the outer carrier 30. This process provides intuitive physical feedback to the operator, clearly informing the user that the controller pull-out operation is about to start, but the system is still running, which helps to prevent user misoperation and take preventive measures in advance.

[0089] During the stage of the action piece 41 moving alone, although the outer carrier 30 has not started to slide, the system is already aware of the impending pull-out action. This provides valuable time for the pre-start of the data backup program, ensuring that the data backup can be fully prepared and started before the mainboard 10 starts to be physically pulled out, thereby avoiding data loss caused by sudden pull-out.

[0090] Through the preliminary movement of the action piece 41, the force acting on the mainboard 10 can be gradually unloaded before the physical separation of the outer carrier 30 and the mainboard 10, reducing the impact force when suddenly pulled out, effectively protecting the mainboard 10 and other connected hardware components, and reducing the risk of hardware damage. Especially in a high-vibration environment or emergency, this design can provide additional protection.

[0091] The setting of the second preset distance allows the action piece 41 to move a certain distance first, during which the outer carrier 30 and the mainboard 10 remain relatively stable, thereby avoiding system instability caused by improper operation or sudden external interference. At the same time, this also provides the operator with the opportunity to confirm the correctness of the operation, increasing the safety of the entire pull-out process.

[0092] The hierarchical motion design of the action piece 41 simplifies the controller node pulling-out process, making the operation more smooth and controllable. Users no longer need to accurately control the force and speed, but only need to operate according to the physical feedback of the action piece 41 to complete the pulling-out of the controller, improving the convenience of operation and the satisfaction of users.

[0093] When encountering earthquakes, transportation vibrations and other external shocks, the advance motion of the action piece 41 can help the system respond quickly and start the data backup mechanism in time, reducing the possibility of hardware damage due to vibration, while also avoiding accidental loss of critical data due to vibration, enhancing the anti-shock ability and emergency response ability of the system.

[0094] The separate motion design of the action piece 41 relative to the first transmission piece 42 and the outer carrier 30 not only optimizes the user operation experience, improves the safety of operation and the stability of the system, but also provides sufficient preparation time for data backup, effectively protecting hardware components and enhancing the anti-shock and emergency response ability of the system.

[0095] In the present application, one of the action piece 41 and the outer carrier 30 is provided with a third sliding part 411, and the other is provided with a third sliding groove 33; the third sliding part 411 is slidably arranged in the third sliding groove 33, so that the action piece 41 is slidable relative to the outer carrier 30.

[0096] When the action piece 41 is pulled out, it passes through the third sliding groove 33, so that the outer carrier 30 forms an idle stroke; at this time, only the action piece 41 is pulled out, without driving the outer carrier 30, and the second sensing part 31 on the outer carrier 30 and the first sensing part 11 on the mainboard 10 still interact with each other, and the system works normally.

[0097] The action piece 41 is pulled out alone, which has no effect on the system, and its role is to inform the user that the mainboard 10 is about to be pulled out to prevent misoperation.

[0135] Optionally, the connector 121 is a high-density connector.

[0136] Optionally, one of the mainboard body 101 and the connector assembly 12 is provided with a guide part 122, and the other is provided with a guide groove 13, the guide part 122 is slidably arranged in the guide groove 13; in the process of connecting the connector assembly 12 and the mainboard body 101, the connection of the connector assembly 12 and the mainboard body 101 is guided by the cooperation of the guide part 122 and the guide groove 13.

[0137] Optionally, the mainboard body 101 or the connector assembly 12 is provided with a guide sleeve 131, and the guide groove 13 is arranged on the guide sleeve 131.

[0138] Optionally, the first sensing part 11 is arranged on the connector assembly 12.

[0139] Optionally, the first sensing part 11 is welded on the mainboard 10.

[0140] Optionally, the height of the first sensing part 11 protruding from the back of the mainboard 10 is not less than 4.5 mm.

[0141] In the present application, the first sensing part 11 is a contact sensor, and the second sensing part 31 is a sensing groove; the contact sensor is located in the sensing groove and contacts the groove wall of the sensing groove, so that the first sensing part 11 and the second sensing part 31 are in mutual sensing cooperation.

[0142] Optionally, the contact sensor is clamped in the sensing groove and contacts the groove wall of the sensing groove, so that the first sensing part 11 and the second sensing part 31 are in mutual sensing cooperation.

[0143] When the controller assembly works normally, the sensing groove and the contact sensor are in contact to inform the system that it works normally, and the user does not need to pull out the mainboard. Once the action part 41 is pulled out to a certain stroke (second preset distance), it will drive the outer carrier 30 to separate from the inner carrier 20 and the mainboard 10, at this time the sensing groove on the outer carrier 30 will separate from the contact sensor on the mainboard 10, and the system will know that the mainboard 10 is about to be pulled out, and start the data backup operation.

[0144] In the present application, the first sensing part 11 is designed as a contact sensor, and the second sensing part 31 is designed as a sensing groove, and the contact sensor can be clamped in the sensing groove and contact the groove wall.

[0145] The contact sensor cooperates with the induction groove to monitor the in-place state of the mainboard 10 in real time. When the controller node is normally inserted and working, the contact sensor is clamped in the induction groove and maintains stable contact with the groove wall. The system can accurately determine whether the controller node is in the normal working position by detecting this physical contact state, thereby providing timely state feedback.

[0146] The direct contact of the contact sensor with the induction groove provides a more reliable signal triggering mechanism. Compared with non-contact induction, this design reduces the possibility of signal interference, ensuring that the contact sensor can timely sense the separation from the induction groove when the controller node is pulled out, thereby accurately triggering the pull-out signal and starting the data backup process.

[0147] By clamping the contact sensor in the induction groove, it can be ensured that the sensor maintains stable contact with the groove wall during the insertion and removal of the controller node, reducing sensor displacement or damage caused by vibration or non-standard operation, and improving the durability and stability of the entire system during long-term use.

[0148] The design of the contact sensor and the induction groove can optimize the spatial layout within the controller assembly. The induction groove is usually designed to be compact and can be embedded in the structure of the outer carrier 30, while the contact sensor can be designed to be more compact and fixed on the mainboard 10. This design not only saves internal space, but also helps to improve the integration and overall aesthetics of the assembly.

[0149] The contact sensing scheme is simpler and more direct than complex wireless sensing or optical sensing technology, reducing the complexity and cost of system design. The cooperation of the contact sensor and the induction groove can achieve signal transmission and state judgment through physical contact, without the need for additional power supply or signal processing circuit, simplifying the internal structure of the controller assembly.

[0150] Especially for the triggering of the data backup process, the cooperation of the contact sensor and the induction groove can provide a clear action trigger point. When the contact sensor is separated from the induction groove, the system immediately starts data backup, avoiding data loss caused by signal delay or misjudgment during the controller node pull-out process, enhancing the immediacy and efficiency of data backup, and improving the data security performance of the entire system.

[0151] The cooperation of the contact sensor and the induction groove realizes real-time monitoring and accurate judgment of the in-place state of the mainboard 10 through direct physical contact, providing a reliable trigger mechanism for the data backup process, while optimizing the spatial layout of the controller assembly and the system design, improving the durability, stability and data security of the assembly.

[0152] Optionally, the first sensing part 11 and the second sensing part 31 are both multiple, and the multiple first sensing parts 11 and the multiple second sensing parts 31 are one-to-one corresponding; when at least one second sensing part 31 moves away from the corresponding first sensing part 11, the pull-out signal is triggered.

[0153] The first sensing part 11 and the second sensing part 31 are both designed as multiple, and the sensing parts are one-to-one corresponding; when at least one second sensing part 31 starts to move away from the corresponding first sensing part 11, the pull-out signal is triggered.

[0154] The configuration of multiple sensing parts increases the redundancy of the system. Even if the sensing cooperation between a certain first sensing part 11 and a second sensing part 31 fails, as long as the distance between any pair of sensing parts changes, the system can capture the pull-out signal. This design significantly improves the reliability and accuracy of detecting the pull-out state of the mainboard 10, ensuring that the data backup mechanism can be activated in the first time to prevent data loss.

[0155] Through one-to-one corresponding arrangement of multiple sensing parts, the system has higher fault tolerance. Even if local hardware failure or abnormal situation is encountered during the controller node pull-out process, as long as one pair of sensing parts can work normally, the pull-out signal can be triggered in time to start the data protection measures, avoiding the overall system failure caused by single point failure.

[0156] The design of multiple sensing parts enhances the adaptability of the system in complex or harsh environments. For example, in high temperature, humidity or severe electromagnetic interference conditions, a single sensing part may be affected by external factors and fail, but the presence of multiple sensing parts can ensure that the system can accurately identify the pull-out action and take protective measures as long as at least one sensing part works normally.

[0157] Through the mutual sensing cooperation between the first sensing part 11 and the second sensing part 31 at the hardware level, the system can simplify its software algorithm without complex data analysis or prediction model. As long as the distance between at least one pair of sensing parts changes, the corresponding pull-out signal can be triggered directly, reducing the complexity and maintenance cost of software development.

[0158] The configuration scheme of multiple sensing parts allows the system to flexibly adjust the number and position of sensing parts according to specific application scenarios and needs. This flexibility provides better scalability and adaptability for the system, facilitating optimization of data backup mechanisms or addition of new functional points in future technology upgrades or product iterations.

[0159] The multiple pairs of induction cooperation design of the first induction part 11 and the second induction part 31 can significantly improve the reliability and efficiency of the system in detecting the state of the mainboard 10 being pulled out, through enhancing redundancy, improving fault tolerance and fine monitoring, and also simplifies the software algorithm, increases the flexible adjustment ability and expansibility of the system, and has important value for improving data security and overall system performance.

[0171] The avoidance part on the inner carrier 20 can effectively reduce the resistance during the pulling-out process. Since the second induction part 31 needs to be separated from the first induction part 11 on the main plate 10 during the pulling-out process, the existence of the avoidance part avoids friction or jamming, so that the outer carrier 30 can more smoothly start its movement relative to the inner carrier 20, improving the smoothness of the pulling-out operation and the user experience.

[0172] The design of the avoidance part not only reduces the pulling-out resistance, but also protects the induction components.
