Description

TECHNICAL FIELD

[0001] The utility model relates to integrated circuit board technical field especially relates to a motor drive integrated circuit board with compression resistance mechanism. BACKGROUND

[0002] In the modern industrial production and science and technology application field, motor drive system is widely used in various equipment, such as automatic production line, electric vehicle, industrial robot etc., and the integrated circuit board for motor drive is one of the key core components in these systems. With the increasing complexity and diversification of these application scenarios, the working environment faced by the integrated circuit board is increasingly harsh. On the one hand, in many industrial production sites, a large amount of dust, debris and other sundries are diffused in the air, which are easy to adhere to the circuit board, not only causing the circuit short circuit, but also affecting the heat dissipation performance of the circuit board due to long-term accumulation, thereby reducing its working efficiency and service life. On the other hand, in some outdoor or humid environments, such as the drive system of electric vehicles and some outdoor industrial equipment, the integrated circuit board is easily eroded by water, such as rainwater and dew. Once the moisture enters the inside of the circuit board, it will cause the electronic components to be damp and corroded, and even cause the entire circuit board to be short-circuited and scrapped in severe cases. Therefore, it has become an important technical problem to be solved in the current field to develop an integrated circuit board for motor drive with high protection performance, which can stably and reliably operate in complex and harsh environments.

[0003] In the prior art, for the protection of the integrated circuit board for motor drive, the common method is to use a simple plastic shell for packaging. Such a plastic shell usually only has a basic physical isolation function, and its structure is relatively simple, mainly containing the circuit board in a simple wrapping way to prevent larger particles of sundries from directly contacting the surface of the circuit board. In terms of waterproofing, some products will apply some ordinary sealant to the interface of the shell to reduce the penetration of moisture, but this sealing method is often not tight enough to resist water immersion or water vapor penetration in high humidity environments for a long time. When dealing with external impact, some circuit boards will add some simple sponge or foam material as a buffer inside the shell, but the buffering performance of these materials is limited and cannot effectively absorb large impact forces, and they are prone to deformation and lose their buffering effect after multiple impacts. In addition, for the heat dissipation problem, the existing technology mostly relies on the heat dissipation design of the circuit board itself, such as arranging heat dissipation copper foil or installing small heat dissipation fins on the circuit board, but after the shell is packaged, the heat dissipation effect of these methods is often affected to a certain extent, and cannot fully meet the heat dissipation needs of the circuit board under high load operation.

[0004] However, this kind of traditional protection method has obvious defects. For example, its protection ability for water source is seriously insufficient. In the face of long time rain washing, water vapor condensation in high humidity environment or accidental water splashing, due to aging, cracking of sealing glue and gap of shell itself, water can easily break through the defense line into the circuit board, thereby causing irreversible damage to electronic components. Moreover, simple plastic shell and limited buffer material cannot effectively block and buffer the impact of external sundries. Once subjected to a larger impact force, such as bumping during transportation, accidental collision in industrial site, etc., the precise components inside the circuit board will be damaged due to vibration and collision, resulting in failure of the entire motor drive system, which seriously affects the normal operation and production efficiency of the equipment. This is a key problem that needs to be overcome for the requirement of equipment stability and reliability in modern industrial production and technological application. Therefore, an integrated circuit board with anti-pressing mechanism for motor drive is proposed to solve the above problems. Practical new type content

Detailed Implementation

[0032] 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.

[0033] Reference Figure 1 - Figure 3 An embodiment of this utility model is provided: an integrated circuit board for motor drive with a pressure-resistant mechanism, including a circuit board 7, and a protective component is provided on the outer wall of the circuit board 7, the protective component acting to protect the circuit board 7;

[0034] The protection assembly comprises a protection shell 1 made of high-strength aluminum alloy material. The material has excellent compression resistance and can effectively resist external impact force. Moreover, the material has good heat conductivity, which is conducive to heat dissipation of the circuit board 7 during operation. The protection shell 1 is arranged on the outer wall of the circuit board 7. A limiting groove 9 is formed in the protection shell 1. The inner wall of the limiting groove 9 is finely polished to ensure smooth sliding of the components matched therewith. Moreover, the dimensional tolerance of the limiting groove 9 is strictly controlled to ensure the tightness and stability of the connection. The protection shell 1 is internally provided with heat dissipation holes 2 arranged in a circular shape. The heat dissipation holes 2 have moderate hole diameters, which can ensure sufficient air flow to promote heat dissipation and prevent a large amount of dust and impurities from entering the interior to affect the performance of the circuit board 7. The outer wall of the protection shell 1 is provided with a waterproof coating 6 made of advanced nanometer waterproof material. The waterproof coating 6 can form a dense waterproof layer to effectively block the penetration of water. The waterproof coating 6 is internally provided with a rubber layer 5 made of high-elasticity silicone rubber material. When subjected to external impact, the silicone rubber can rapidly elastically deform to uniformly disperse the impact force, thereby buffering and protecting the internal circuit board 7. The protection shell 1 is provided with a top cover 3. The top cover 3 is provided with a connecting ring 4 at the bottom. The connecting ring 4 is fixedly connected with a limiting plate 8 at the bottom. The limiting plate 8 is slidably connected to the limiting groove 9. The protection shell 1 is internally provided with a buffering assembly.

[0035] Specifically, to enhance the protection performance of the integrated circuit board 7 for motor driving, multiple protection measures are adopted. The circuit board 7 is provided with the protection shell 1 and the top cover 3, which provides a preliminary protection barrier for the device and effectively resists daily collisions and scratches. The waterproof coating 6 at the top acts as a tight shield to effectively block the intrusion of external water sources and ensure that the internal circuit of the circuit board 7 is not threatened by water disasters. The rubber layer 5 at the bottom of the waterproof coating 6 plays a key role in sensing and absorbing external impact force and uniformly dispersing the impact force, thereby comprehensively protecting the internal circuit. Moreover, the top cover 3 can be flexibly slid within the protection shell 1, which further moderates external impact and greatly improves the stability and reliability of the circuit board 7 in complex environments, thereby laying a solid foundation for stable operation of the motor driving system.

[0036] Reference Figure 1 , Figure 3 and Figure 4The buffer assembly comprises a fixed column 10 made of high-strength stainless steel, which has good rigidity and corrosion resistance to ensure the stability of the structure during long-term use. The fixed column 10 is arranged inside the protective shell 1, and the bottom of the fixed column 10 is fixedly connected with a fixed plate 17, and the bottom of the fixed plate 17 is fixedly connected to the inner wall of the protective shell 1. A connecting ring 18 is slidably connected to the outer wall of the fixed column 10, and a spring 19 is sleeved on the outer wall of the fixed column 10, and the both ends of the spring 19 are fixedly connected to the outer wall of the connecting ring 18. The connecting ring 18 is made of wear-resistant engineering plastic with certain self-lubricating performance, which can ensure smooth sliding between the fixed column 10 and the connecting ring 18, reduce friction loss, and prolong the service life. A rotating rod 14 is rotatably connected to the outer wall of the connecting ring 18, and the rotating rod 14 is made of high-strength aluminum alloy and is precisely machined to ensure its flexibility and stability. The other end of the rotating rod 14 is rotatably connected with a sliding ring 13. A damper 11 is fixedly connected to the top of the fixed column 10, and the inside of the damper 11 is filled with high-viscosity hydraulic oil. The piston rod and cylinder body of the damper 11 are made of high-quality alloy steel, which has good sealing performance and wear resistance, and can generate stable damping force during the extension and retraction of the piston rod, effectively consuming impact energy. The top of the damper 11 is fixedly connected with a connecting column 12, and the sliding ring 13 is slidably connected to the outer wall of the connecting column 12. A limiting ring 20 is fixedly connected to the outer wall of the connecting column 12. A connecting plate 15 is fixedly connected to the top of the limiting plate 8. A spring 16 is sleeved on the outer wall of the damper 11, and the bottom of the spring 16 is fixedly connected to the outer wall of the fixed column 10. The top of the spring 16 is fixedly connected to the bottom of the connecting column 12. The material of the spring 16 is the same as that of the spring 19, which is a high-elasticity alloy spring steel wire. The bottom of the spring 16 is fixedly connected to the outer wall of the fixed column 10 by a special fixing ring, and the top is fixedly connected to the bottom of the connecting column 12. The spring 16 works with the damper 11. When impacted, the spring 16 first deforms elastically to store part of the energy, and the damper 11 generates damping force to consume energy. The rebounding process of the spring 16 is also controlled by the damper 11, making the entire buffering process more stable and efficient, thereby providing reliable buffering protection for the circuit board 7 and ensuring its stable operation in complex working environments, preventing damage from external impact forces, and greatly improving the reliability and service life of the entire motor-driven integrated circuit board 7.

[0037] Specifically, when the entire device is subjected to external impact, the top cover 3 will quickly respond and move downward. The downward movement of the top cover 3 will drive the connected plate 15 to move synchronously, and the connected plate 15 will in turn push the connecting column 12 to move vertically downward. In this process, the connecting column 12 will exert pressure on the damper 11, so that the damping medium inside the damper 11 generates resistance and consumes impact energy, and at the same time, the spring 16 will also be compressed to store elastic potential energy to buffer the impact. At the same time, the downward movement of the connecting column 12 will also make the sliding ring 13 slide along the outer wall thereof, and the displacement of the sliding ring 13 will drive the rotating rod 14 to rotate, and the rotation of the rotating rod 14 will push the connecting ring 18 to move on the outer wall of the fixed column 10, thereby compressing the spring 19 to further absorb impact energy. After the impact ends, the damper 11, the spring 16 and the spring 19 will rebound by virtue of their own characteristics to restore to the initial state, and in this process, the remaining impact energy is continuously absorbed and dissipated. Through this series of precise linkage mechanisms, the internal circuit board 7 is effectively protected from damage by impact, greatly improving the reliability and stability of the entire device under complex working conditions, and ensuring that the motor driving system can operate stably and safely.

[0038] Working principle: The device is preliminarily protected by the protective shell 1 and the top cover 3 arranged on the outer wall of the circuit board 7, and at the same time, the water source is protected by the waterproof coating 6 on the top, preventing external water from entering, and the bottom of the waterproof coating 6 is provided with a rubber layer 5 to absorb and disperse external impact and protect the inside, and the sliding of the top cover 3 inside the protective shell 1 is moderated.

[0039] In addition, when impacted, the top cover 3 moves downward to drive the connected plate 15 to move, and then the connected plate 15 drives the connecting column 12 to move downward to press the damper 11 and compress the spring 16, and at the same time, the sliding ring 13 is driven to slide on the outer wall of the connecting column 12 to drive the rotating rod 14 to rotate to push the connecting ring 18 on the outer wall of the fixed column 10 to compress the spring 19, so as to absorb the pressure, and then the device is rebounded by the rebound of the damper 11, the spring 16 and the spring 19 to absorb the pressure, thereby protecting the internal circuit board 7.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
