TECHNICAL FIELD
[0001] The utility model relates to a relay technology field especially relates to a safe relay with shock attenuation function. BACKGROUND
[0002] In industrial automation control systems, relays are a kind of key control elements. They are used to realize signal conversion, amplification and logic control functions. For example, in the automated production line, relays can control the start and stop of the motor, the running speed of the conveyor belt, etc. With the continuous improvement of industrial automation, the reliability and stability of relays are also increasingly required. Vibration may occur during the operation of the equipment, which may be caused by the operation of the motor, the movement of mechanical parts, etc. For example, in the factory workshop, the punch press machine will produce strong vibration when working. If these vibrations are transmitted to the relay, it may cause the contacts inside the relay to malfunction. The malfunction of the relay contacts may cause the entire automation control system to malfunction, such as sending incorrect instructions to the production line, resulting in a decline in product quality or even damage to the equipment.
[0003] Due to the important role of relays in many electrical control systems, they are used to realize circuit on-off control, signal conversion, etc. However, in some special environments, such as strong vibration caused by large-scale machinery operation in industrial production sites, jolt vibration during transportation tool operation, etc., ordinary relays are prone to internal component loosening and displacement due to vibration, which may cause poor contact, malfunction or even damage of the contacts, seriously affecting the normal operation and safety of the electrical system. Therefore, the technical personnel in the field provide a safe relay with shock attenuation function to solve the problems existing in the above. SUMMARY
[0004] The utility model aims at solving the shortcomings existing in the prior art and provides a safe relay with shock attenuation function.
[0005] In order to realize the above object, the utility model provides the following technical scheme: A safety relay with damping function, including relay body constitutes core frame, its bottom is equipped with damping base. The inside wall bottom middle position of relay body is installed with transmission seat, the inside wall of damping base is equipped with installation groove, the inside wall bottom of installation groove is installed with mounting plate. The top middle position of mounting plate is installed with damper, the top middle position of damper is connected with connecting piece, the top of connecting piece is installed with H type connecting plate, and the both sides positions of the inside wall of H type connecting plate are rotatably connected with stress plate. The both sides positions of the top middle of mounting plate are installed with U type block, and the inside wall of U type block is equipped with first driven spring, and the rotating end of stress plate is installed in the inside wall of damper and stress plate respectively. The middle positions of the front wall and the back wall of H type connecting plate are installed with connecting plate, and the both side walls of connecting plate are installed with Z type plate respectively, and the bottom of Z type plate is installed with second driven spring, and the bottom of second driven spring is installed in the top of installation groove, and transmission seat is connected with H type connecting plate. In addition, the inside of relay body further includes coil, electromagnetic system, armature system and contact system, and the relay body further includes display screen and control panel.
[0006] Preferably, the damping base (as a whole damping foundation structure, provides installation space and protection for internal damping components. Its installation groove contains other damping related components, making the entire damping structure compact and orderly carrying damper, U-shaped block and other key damping elements, ensuring that they can stably play a role when subjected to vibration, and the stable installation position ensures effective transmission and dispersion of damping force. When the vibration is transmitted to the damping base, the damper converts the vibration energy into heat energy and other forms of dissipation by using the viscous resistance of the internal damping medium (such as hydraulic oil, gas, etc.). Its connection with the connecting piece enables direct damping and buffering of the H-shaped connecting plate and the components above, effectively reducing the amplitude of vertical vibration.
[0007] Preferably, the first driven spring is installed in the inside wall of the U-shaped block. In horizontal vibration, the elastic deformation of the spring can absorb and buffer the vibration energy, and work with the damper to suppress vibration from multiple directions, enhancing the overall damping effect and providing some assistance to the stability of the contact system during operation.
[0008] Preferably, the second driven spring is connected to the H-shaped connecting plate through the Z-shaped plate and the connecting plate, providing additional elastic support and buffering for the H-shaped connecting plate when the relay is in operation and subjected to vibration. On the one hand, it assists the action of the contact system to ensure its smooth operation; on the other hand, it plays a complementary role in damping, further optimizing the adaptability of the relay in complex vibration environments.
[0009] Preferably, the electromagnetic system is closely matched with the coil, and when the coil is supplied with current, a magnetic field is generated, and the electromagnetic system generates electromagnetic force under the action of the magnetic field to drive the armature system to act.
[0010] Preferably, the H-shaped connecting plate drives the stress plate to rotate under the drive of the transmission seat, and simultaneously transmits the action to the contact system through the connecting piece. The stress plate plays a role of force distribution and transmission in this process, ensures that the contact system can be uniformly stressed, and stably completes the action, and reduces the contact failure caused by uneven stress.
[0011] Preferably, various working state information of the relay can be displayed in real time, such as the on-off state of the contact, the coil current, whether there is a fault alarm and the like. Through intuitive display, the operator can timely understand the running condition of the relay, and provide a strong basis for fault troubleshooting and system maintenance. The operator can perform various operation controls on the relay through the control panel.
[0012] The utility model has the following beneficial effects:
[0013] 1. In the utility model, the damping base and the damper, the first driven spring and the second driven spring and other components inside the damping base can effectively absorb and buffer various vibrations received by the relay in the working process. Compared with the traditional relay, the internal structure of the relay is less likely to displace, loosen or damage due to vibration in a vibrating environment (such as near large mechanical equipment in industrial production, electrical systems of transportation tools, etc.), thereby greatly reducing the probability of misoperation or failure caused by vibration, and significantly improving the stability and reliability of the relay. The electrical control circuit can continuously and accurately perform the predetermined control function, reducing the risk of production interruption, equipment damage or safety accidents caused by relay failure, and improving the safety and operating efficiency of the entire electrical system.
[0014] 2. In the utility model, the first driven spring and the second driven spring play an auxiliary role in the action and reset process of the contact system. They can provide more precise force control for the closing and opening of the contact, making the contact pressure more uniform and stable, and reducing the possibility of bounce and arc generation between the contacts. Compared with the prior art, this helps to prolong the service life of the contact, reduce the maintenance cost of frequently replacing the relay due to contact wear and ablation, and further improve the electrical performance and stability of the relay under frequent on-off operation, ensuring the accuracy and integrity of the circuit signal transmission.

Its installation groove 20 contains other shock absorption related components, so that the whole shock absorption structure is compact and orderly carries key shock absorption elements such as damper 11, U type block 9, etc., to ensure that they can stably play a role when subjected to vibration, and its stable installation position ensures the effective transmission and dispersion of shock absorption force. When the vibration is transmitted to shock absorption base 2, damper 11 converts the vibration energy into heat energy and other forms by using the viscous resistance of internal damping medium such as hydraulic oil, gas, etc. Its connection with connecting piece 12 enables H type connecting plate 7 and the components above to be directly shock-absorbed and buffered, effectively reducing the vibration amplitude in the vertical direction. First driven spring 16 is installed in the inside wall of U type block 9, and in horizontal vibration, the elastic deformation of the spring can absorb and buffer the vibration energy, and cooperates with damper 11 to suppress vibration from multiple directions, enhancing the overall shock absorption effect, while also providing certain assistance for the stability of contact system 13 during operation.

The mounting plate 10 in the mounting groove 20 of the inner side wall is provided with a damper 11. The damper 11 is connected with the H-shaped connecting plate 7 through the connecting piece 12. When the relay is vibrated, the vibration is transmitted to the damper 11 through the H-shaped connecting plate 7. The damper 11 can absorb and dissipate the vibration energy. At the same time, the first driven spring 16 in the U-shaped block 9 at the top of the mounting plate 10 and the second driven spring 19 connected with the Z-shaped plate 18 at the bottom of the H-shaped connecting plate 7 are elastically deformed, which can assist in absorbing vibration energy and enhance the damping effect.
[0026] In the relay action aspect, the body has a coil 3, an electromagnetic system 4, an armature system 5, a transmission seat 6 and a contact system 13 inside. When the current passes through the coil 3 to generate a magnetic field, the electromagnetic system 4 interacts with the coil 3, and under the action of the magnetic field, the electromagnetic system 4 cooperates with the armature system 5 to move the armature system 5. The transmission seat 6 located at the middle position of the bottom of the inner wall of the relay body 1 and connected with the H-shaped connecting plate 7 drives the H-shaped connecting plate 7 and the stress plate 8.

In addition, the relay body 1 also includes a display screen 14 and a control panel 15.
