Description

Technical Field

[0001] The present invention relates to the technical field of controllers, and particularly to an intelligent terminal controller with a shock-absorbing structure. Background Art

[0002] In the field of power distribution network automation, intelligent terminal controllers play a crucial role. They are responsible for monitoring, controlling, and debugging various power equipment to ensure the stable operation of the power system. In today's power distribution network automation systems, intelligent terminal controllers (such as deeply integrated feeder terminal debugging tools) are indispensable key devices. Due to their working nature, they need to be frequently moved and operated in complex outdoor environments. However, traditional protective designs have exposed many defects:

[0003] Insufficient shock resistance: Most of the current intelligent terminal controller housings on the market are made of hard plastics or metals. When the device drops, this material cannot effectively buffer the impact force, resulting in the impact force being directly transmitted to the internal circuit. According to industry statistics, the component damage rate is as high as 15%-20%. This not only affects the normal use of the device but also increases the maintenance cost and the instability of the power system operation.

[0004] Bulky shock-absorbing structure: Traditional shock-absorbing solutions usually use solid rubber pads with a thickness of ≥8mm. Although this design can play a shock-absorbing role to a certain extent, it significantly increases the weight of the device, with the weight increase ranging from 30% to 40%. In the current trend of miniaturization and lightweight of devices, this bulky shock-absorbing structure seriously hinders the development of products.

[0005] Poor environmental adaptability: The performance of ordinary rubber materials is greatly affected by temperature. In low-temperature environments (< -20°C), the rubber will harden and lose its original elasticity and buffering ability; while in high-temperature environments (> 60°C), the rubber will soften, resulting in a shock-absorbing efficiency reduction of more than 50%. This makes the intelligent terminal controller unable to function properly in extreme temperature environments, restricting its application range.

[0006] High maintenance cost: Traditional shock-absorbing structures are mostly integrated designs. Once a local damage occurs, the entire shock-absorbing structure needs to be replaced. This not only increases the difficulty and time cost of maintenance but also significantly raises the operation and maintenance cost, bringing a greater economic burden to power enterprises.

[0007] Therefore, how to design an intelligent terminal controller with a shock-absorbing structure that can improve the shock resistance, weather resistance, and maintenance efficiency of the intelligent terminal controller through a composite shock-absorbing structure and modular design to adapt to complex outdoor working environments is an urgent problem for those skilled in the art to solve. Summary of the Invention

[0008] In view of this, the present invention provides an intelligent terminal controller with a shock absorption structure, aiming to solve the technical problems of poor anti-drop performance, difficult disassembly and assembly of the shock absorption structure, and low maintenance and replacement efficiency of the conventional terminal controller.

[0009] To achieve the above object, the present invention adopts the following technical solutions:

[0010] The present invention provides an intelligent terminal controller with a shock absorption structure, including:

[0011] A box body, on one end face of which a cable socket is installed;

[0012] A circuit module, which is installed inside the box body and electrically connected to the cable socket;

[0013] A hollow shock-absorbing soft cover one, which covers the end face one of the box body and is detachably snap-connected to the box body; a socket avoidance through hole is provided at the position corresponding to the cable socket on the hollow shock-absorbing soft cover one; the cable socket passes through the socket avoidance through hole; a shock-absorbing cavity one is provided inside the hollow shock-absorbing soft cover one; the shock-absorbing cavity one is filled with a shock-absorbing colloid;

[0014] A hollow shock-absorbing soft cover two; the hollow shock-absorbing soft cover two covers the end face two of the box body opposite to the end face one and is detachably snap-connected to the box body; a shock-absorbing cavity two is provided inside the hollow shock-absorbing soft cover two; the shock-absorbing cavity two is filled with a shock-absorbing colloid.

[0015] By adopting a composite shock-absorbing structure with hollow shock-absorbing soft covers and shock-absorbing colloid filled inside at both ends of the intelligent terminal controller of the present invention, the anti-impact performance is significantly improved, which can ensure that the internal components are not damaged when the device drops, and effectively reduce the risk of device failure caused by dropping. The hollow shock-absorbing soft cover one and the hollow shock-absorbing soft cover two only cover the two end parts of the box body, which will not affect the heat dissipation performance of the box body; both the hollow shock-absorbing soft cover one and the hollow shock-absorbing soft cover two are detachably snap-connected to the box body, which is convenient for disassembling and assembling the box body and replacing the shock-absorbing structure, can reduce the maintenance cost, and prolong the service life of the device.

[0016] As a further improvement of the above technical solution, a slot one is provided on one end face of the hollow shock-absorbing soft cover one, and the socket avoidance through hole is provided on the bottom wall of the slot one; the end part of the box body corresponding to the end face one is inserted into the slot one;

[0017] A slot two is provided on one end face of the hollow shock-absorbing soft cover two; the end part of the box body corresponding to the end face two is inserted into the slot two.

[0018] The beneficial effect of the above technical solution is that the two ends of the box body are respectively embedded in the slot one and the slot two, realizing the full-range protection of the end parts of the box body.

[0019] As a further improvement of the above technical solution, plug-in blocks are provided on both the first end face of the box body and the second end face opposite to the first end face.

[0020] A first plug-in slot is provided on the bottom wall of the first slot corresponding to the outer peripheral side of the socket avoidance through hole; the plug-in block on the first end face of the box body is connected to the first plug-in slot in a pluggable and lockable manner.

[0021] A second plug-in slot is provided on the bottom wall of the second slot, and the plug-in block on the second end face of the box body is connected to the second plug-in slot in a pluggable and lockable manner.

[0022] The beneficial effect of the above technical solution is that since both the first hollow shock-absorbing soft cover and the second hollow shock-absorbing soft cover have a certain degree of softness, it is convenient for the plug-in blocks to be squeezed and inserted into or pulled out from the corresponding first plug-in slot and second plug-in slot, making the pluggable and lockable connection operation more convenient and supporting the quick disassembly, installation or replacement of the first hollow shock-absorbing soft cover and the second hollow shock-absorbing soft cover; especially when the intelligent terminal controller is arranged at a high position such as on a telegraph pole, the construction and maintenance personnel can disassemble, install or replace the first hollow shock-absorbing soft cover and the second hollow shock-absorbing soft cover with one hand, reducing the construction risk and improving the construction efficiency.

[0023] As a further improvement of the above technical solution, a first rubber pad is provided between the first end face of the box body and the inner wall of the first plug-in slot; a second rubber pad is provided between the second end face of the box body and the inner wall of the second plug-in slot.

[0024] The beneficial effect of the above technical solution is that the first rubber pad and the second rubber pad can further increase the shock-absorbing effect.

[0025] As a further improvement of the above technical solution, the end of the cable socket away from the box body extends out of the socket avoidance through hole; on both sides of the end wall of the first hollow shock-absorbing soft cover away from the box body, a protective enclosure structure is formed by extending in a direction away from the box body.

[0026] The beneficial effect of the above technical solution is that the protective enclosure structure plays an effective role in protecting the cable socket.

[0027] As a further improvement of the above technical solution, a first grasping groove is provided in the middle of both sides in the width direction of the first hollow shock-absorbing soft cover and the second hollow shock-absorbing soft cover.

[0028] The beneficial effect of the above technical solution is that by providing the first grasping groove on the first hollow shock-absorbing soft cover and the second hollow shock-absorbing soft cover, it is convenient for the construction and maintenance personnel to carry, grasp, disassemble and install the first hollow shock-absorbing soft cover and the second hollow shock-absorbing soft cover.

[0029] As a further improvement of the above technical solution, the box body is a sealed flame-retardant box body and its outer surface is coated with a conductive coating.

[0030] The beneficial effects of the above technical solution are: the sealed flame-retardant box body is fireproof and rainproof, and the conductive coating coated on the surface not only gives the box body an electromagnetic shielding function, but also can effectively prevent the influence of external electromagnetic interference on the internal circuit, providing multiple guarantees for the stable operation of the equipment.

[0031] As a further improvement of the above technical solution, the wall thickness of the hollow shock-absorbing soft cover 1 and the hollow shock-absorbing soft cover 2 are both 3-5mm; the volume of the shock-absorbing cavity 1 is 60%-70% of the total volume of the hollow shock-absorbing soft cover 1; the volume of the shock-absorbing cavity 2 is 60%-70% of the total volume of the hollow shock-absorbing soft cover 2.

[0032] The beneficial effects of this technical solution are: a thickness designed between 3-5mm ensures a certain cushioning effect without adding excessive weight. The composite shock-absorbing structure achieves a lightweight controller design, significantly reducing the overall weight compared to traditional solutions, meeting the trend of device miniaturization and making it easier to carry and operate. The 60%-70% volume of the shock-absorbing cavity deforms first upon impact, absorbing a large amount of the initial impact energy.

[0033] As a further improvement of the above technical solution, the first hollow shock-absorbing soft cover and the second hollow shock-absorbing soft cover are both made of silicone rubber; and the shock-absorbing colloid is polyurethane shock-absorbing glue.

[0034] The beneficial effects of the above technical solution are: the hollow shock-absorbing soft cover is made of silicone rubber, which has good flexibility and elasticity; when the device is impacted, the shock-absorbing colloid can disperse the remaining energy with its high resilience, and the synergistic effect of the two can effectively reduce the peak impact force.

[0035] As a further improvement of the above technical solution, the density of the shock absorbing colloid is 0.8-1.2g / cm 3 , Shore A hardness is 30A-50A; nano-silicon dioxide particles with a particle size of 20-50nm are evenly added to the shock-absorbing colloid, and the addition amount of the nano-silicon dioxide particles accounts for 3%-5% of the total mass of the shock-absorbing colloid.

[0036] The beneficial effect of the above technical solution is that the added nano-silica particles can further enhance the compression deformation resistance of the shock-absorbing colloid, so that it can still maintain good elasticity and cushioning performance under long-term impact and extrusion, thereby extending the service life of the equipment.

[0037] It can be seen from the above technical solutions that, compared with the prior art, the present invention discloses an intelligent terminal controller with a shock-absorbing structure, which has the following advantages and beneficial effects:

[0038] 1. The impact resistance of the intelligent terminal controller of the present invention is significantly improved. By filling with polyurethane (PU) shock-absorbing glue, it can absorb the kinetic energy generated when the device drops or collides, effectively reducing the damage to the internal circuit caused by the impact force. Through actual testing, the failure rate of the device using this design can be reduced by more than 40% compared with traditional devices, greatly improving the reliability and stability of the device.

[0039] 2. The intelligent terminal controller of the present invention realizes a lightweight design. By using the hollow structures of the hollow shock-absorbing soft cover one and the hollow shock-absorbing soft cover two, combined with the low-density PU shock-absorbing glue, the overall weight can be reduced by 30% compared with traditional rubber pads. This design meets the development needs of modern devices for miniaturization and lightweight, facilitating the staff to carry and operate.

[0040] 3. The environmental adaptability of the intelligent terminal controller of the present invention is enhanced. The optimized PU shock-absorbing glue can maintain stable elasticity within a wide temperature range from -40°C to 80°C. At the same time, it also has good oil resistance and hydrolysis resistance, and can adapt to complex outdoor working conditions. Whether it is high temperature, low temperature, humid or oily environment, it will not have a great impact on the shock-absorbing performance of the device.

[0041] 4. The maintenance of the intelligent terminal controller of the present invention is more convenient. Adopting a plug-and-play detachable design, when the shock-absorbing soft cover is damaged or needs to be cleaned, it can be quickly replaced without complex tools. This design not only saves maintenance time and cost, but also extends the service life of the device and improves the operation and maintenance efficiency of the power system.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] According to an embodiment of the present invention, as Figures 1 to 3 shown, an intelligent terminal controller with a shock-absorbing structure includes: a box body 1, a circuit module 2, a first hollow shock-absorbing soft cover 3, and a second hollow shock-absorbing soft cover 4.

[0052] A cable socket 5 is installed on the first end face 11 of the box body 1; the circuit module 2 is installed inside the box body 1 and is electrically connected to the cable socket 5.

[0053] A hollow shock-absorbing soft cover 3 is covered at the first end face 11 of the box body 1 and is connected to the box body 1 by a plug-in snap connection; a socket avoidance through hole 31 is provided at the position corresponding to the cable socket 5 on the hollow shock-absorbing soft cover 3; the cable socket 5 is inserted through the socket avoidance through hole 31; a shock-absorbing cavity 32 is provided inside the hollow shock-absorbing soft cover 3; the shock-absorbing cavity 32 is filled with shock-absorbing colloid.

[0054] A hollow shock-absorbing soft cover 4 is covered at the second end face 12 of the box body 1 opposite to the first end face 11 and is connected to the box body 1 by a plug-in snap connection; a shock-absorbing cavity 41 is provided inside the hollow shock-absorbing soft cover 4; the shock-absorbing cavity 41 is filled with shock-absorbing colloid.

[0055] In this embodiment, both ends of the intelligent terminal controller with a shock-absorbing structure adopt a composite shock-absorbing structure of a hollow shock-absorbing soft cover and a shock-absorbing colloid filled inside, significantly improving the anti-impact performance, ensuring that the internal components are not damaged when the device drops, and effectively reducing the risk of device failure caused by dropping. The hollow shock-absorbing soft cover 3 and the hollow shock-absorbing soft cover 4 only cover the two ends of the box body 1, and will not affect the heat dissipation performance of the box body 1; both the hollow shock-absorbing soft cover 3 and the hollow shock-absorbing soft cover 4 are connected to the box body 1 by a plug-in snap connection, which is convenient for disassembling and assembling the box body and replacing the shock-absorbing structure, can reduce the maintenance cost, and extend the service life of the device.

[0056] Specifically, the cable socket 5 can be adaptively inserted and connected with a cable with an aviation plug to be electrically connected and communicate with an external device. The cable socket 5 selects an existing product.

[0057] In some embodiments, a slot 33 is provided on one end face of the hollow shock-absorbing soft cover 3, and the socket avoidance through hole 31 is provided on the bottom wall of the slot 33; the end of the box body 1 corresponding to the first end face 11 is inserted into the slot 33;

[0058] A slot 42 is provided on one end face of the hollow shock-absorbing soft cover 4; the end of the box body 1 corresponding to the second end face 12 is inserted into the slot 42.

[0059] Both ends of the box body 1 are respectively embedded in the slot 33 and the slot 42, realizing the full-range protection of the ends of the box body 1.

[0060] In some embodiments, plug-in snap blocks 13 are provided on both the first end face 11 of the box body 1 and the second end face 12 opposite to the first end face 11;

[0061] A plug-in snap groove 331 is provided on the bottom wall of the slot 33 corresponding to the outer peripheral side of the socket avoidance through hole 31; the plug-in snap block 13 on the first end face 11 of the box body 1 is adaptively connected to the plug-in snap groove 331 by a plug-in snap connection;

[0062] The bottom wall of the second slot 42 is provided with a second plug-in card slot 421, and the plug-in card block 13 on the second end face 12 of the box body 1 is adapted to be plugged and buckled with the second plug-in card slot 421.

[0063] Since both the hollow shock-absorbing soft cover 1 and the hollow shock-absorbing soft cover 2 have a certain degree of softness, it is convenient for the plug-in card block 13 to be squeezed and inserted or pulled out of the corresponding first plug-in card slot 331 and the second plug-in card slot 421, making the plug-and-play buckle connection operation more convenient and supporting the quick disassembly, installation or replacement of the hollow shock-absorbing soft cover 1 and the hollow shock-absorbing soft cover 2; especially when the intelligent terminal controller is arranged at a high position such as on a telegraph pole, the construction and maintenance personnel can disassemble, install or replace the hollow shock-absorbing soft cover 1 and the hollow shock-absorbing soft cover 2 with one hand, and the replacement time can be controlled within 30 seconds, reducing the construction risk and improving the construction efficiency.

[0064] In some embodiments, a first rubber pad 6 is provided between the first end face 11 of the box body 1 and the inner wall of the first plug-in card slot 331; a second rubber pad 7 is provided between the second end face 12 of the box body 1 and the inner wall of the second plug-in card slot 421.

[0065] The first rubber pad 6 and the second rubber pad 7 can further increase the shock-absorbing effect.

[0066] In some embodiments, the end of the cable socket 5 far from the box body 1 extends out of the socket avoidance through hole 31; on both sides of the end wall of the hollow shock-absorbing soft cover 1 far from the box body 1, a protective enclosure structure 34 is formed by extending in a direction away from the box body 1.

[0067] The protective enclosure structure 34 effectively protects the cable socket 5.

[0068] In some embodiments, a first gripping groove pair 35 is provided in the middle of both sides in the width direction of the hollow shock-absorbing soft cover 1 and the hollow shock-absorbing soft cover 2.

[0069] The first gripping groove pair 35 is provided on the hollow shock-absorbing soft cover 1 and the hollow shock-absorbing soft cover 2, which is convenient for the construction and maintenance personnel to carry, grasp, disassemble and install the hollow shock-absorbing soft cover 1 and the hollow shock-absorbing soft cover 2.

[0070] In some embodiments, the box body 1 is a sealed flame-retardant box body and its outer surface is coated with a conductive coating 8.

[0071] The sealed flame-retardant box body can prevent fire and rain. The conductive coating 8 coated on the surface not only endows the box body with electromagnetic shielding function, but also can effectively prevent the influence of external electromagnetic interference on the internal circuit, providing multiple guarantees for the stable operation of the equipment.

[0072] In some embodiments, the wall thicknesses of the first hollow shock-absorbing soft cover 3 and the second hollow shock-absorbing soft cover 4 are both 3 - 5 mm; the volume of the first shock-absorbing cavity 32 is 60% - 70% of the total volume of the first hollow shock-absorbing soft cover 3; the volume of the second shock-absorbing cavity 41 is 60% - 70% of the total volume of the second hollow shock-absorbing soft cover 4.

[0073] The thickness range of 3 - 5 mm for the wall thicknesses of the first hollow shock-absorbing soft cover 3 and the second hollow shock-absorbing soft cover 4 has been carefully considered. The thickness of 3 mm is the lower limit to meet the basic shock-absorbing requirements and lightweight requirements, which can minimize the increase in the overall weight of the device while ensuring a certain shock-absorbing performance; while the thickness of 5 mm is the upper limit to enhance the shock-absorbing effect without affecting the portability of the device. It not only ensures a certain shock-absorbing effect but also does not increase too much weight. Through the composite shock-absorbing structure design, the lightweight design of the controller is realized, and the overall weight is greatly reduced compared with the traditional solution, which can meet the development trend of device miniaturization and is more convenient to carry and operate. The volume of the internal hollow cavity of the first hollow shock-absorbing soft cover 3 or the second hollow shock-absorbing soft cover 4 accounts for 60% - 70% of the total volume of the sleeve body. Such a volume ratio maximizes the ability of the shock-absorbing colloid in the hollow cavity to absorb impact energy while ensuring the structural strength of the soft rubber sleeve. And, the cross-sectional shapes of the first shock-absorbing cavity 32 and the second shock-absorbing cavity 41 can be designed as trapezoidal or semi-circular. When the shock-absorbing colloid with a trapezoidal cross-section is subjected to an impact, it can use its special geometric shape to more effectively disperse the impact force to various parts of the soft rubber sleeve (the first hollow shock-absorbing soft cover 3 or the second hollow shock-absorbing soft cover 4); the semi-circular cross-section has better structural stability and is not easily deformed under repeated impacts. Both shapes can provide a strong guarantee for the shock-absorbing effect and can deform first when subjected to an impact, absorbing a large amount of initial impact energy.

[0074] In some embodiments, both the first hollow shock-absorbing soft cover 3 and the second hollow shock-absorbing soft cover 4 are made of silicone rubber; the shock-absorbing colloid is polyurethane shock-absorbing glue.

[0075] The first hollow shock-absorbing soft cover 3 is made of silicone rubber, which has excellent flexibility, elasticity and weather resistance, and can maintain stable performance in various complex environments; when the device is subjected to an impact, the shock-absorbing colloid can disperse the remaining energy with its high resilience. The two work together to effectively reduce the peak impact force.

[0076] At one end of the first hollow shock-absorbing soft cover 3 and the second hollow shock-absorbing soft cover 4 away from the box body 1, glue injection holes are provided, and the shock-absorbing colloid is injected into the first shock-absorbing cavity 32 of the first hollow shock-absorbing soft cover 3 and the second shock-absorbing cavity 41 of the second hollow shock-absorbing soft cover 4 through the glue injection holes; the vacuum glue injection method can be used to make the shock-absorbing colloid evenly distributed in the corresponding first shock-absorbing cavity 32 and second shock-absorbing cavity 41.

[0077] In some embodiments, the density of the shock-absorbing colloid is 0.8 - 1.2 g / cm3 The Shore A hardness is 30A - 50A; nano-silica particles with a particle size of 20 - 50 nm are uniformly added to the shock-absorbing colloid, and the addition amount of the nano-silica particles accounts for 3% - 5% of the total mass of the shock-absorbing colloid.

[0078] The addition amount of the nano-silica particles is 3% - 5% of the total mass of the shock-absorbing colloid, and this addition ratio is obtained through a large number of experimental optimizations; the added nano-silica particles can further improve the compression set resistance performance of the shock-absorbing colloid, enabling it to maintain good elasticity and buffering performance under long-term impact and extrusion, thereby extending the service life of the device.

[0079] Specifically, the shock-absorbing colloid can be a polyurethane (PU) shock-absorbing glue; the density of the shock-absorbing colloid is set to 0.8 - 1.2 g / cm 3 , and the selection of this density range is determined through a large number of experiments and studies. At this density, the PU shock-absorbing glue can not only ensure good fluidity, but also be convenient for uniform filling in the inner cavities of the hollow shock-absorbing soft cover 3 and the hollow shock-absorbing soft cover 4, and can also have an appropriate mass, matching the overall lightweight design. The Shore A hardness range of 30A - 50A enables the PU shock-absorbing glue to have good elasticity and resilience. When subjected to external force impact, it can quickly deform to absorb energy and quickly return to its original state after the impact to continue to play a buffering role. In addition, the temperature resistance range of the PU shock-absorbing glue is -40°C to 80°C, which means that within a wide range of ambient temperatures from extremely cold to high temperature, it can maintain stable physical properties and will not have problems such as hardening, softening, or loss of elasticity due to temperature changes, ensuring the reliable operation of the device in different environments; moreover, its oil resistance meets the ASTM D471 standard, which makes the PU shock-absorbing glue not be eroded by oil substances in outdoor working scenarios where it may come into contact with oil stains, ensuring the durability of the shock-absorbing performance.

[0080] Specifically, to improve the weather resistance of the shock-absorbing colloid, the formula of the PU shock-absorbing glue can be adjusted, and a hydrolysis-resistant agent component can be added. After such optimization, in a humid and hot environment (humidity 90%), the elasticity retention rate of the PU shock-absorbing glue > 85%, significantly improving the performance stability of the PU shock-absorbing glue in harsh environments and making it more suitable for outdoor complex working conditions.

[0081] Specifically, the box body 1 is rectangular parallelepiped-shaped, and its material is flame-retardant ABS plastic. The flame-retardant ABS plastic has good mechanical properties and processing properties, can meet the requirements of the shell for strength and forming process, and has flame-retardant characteristics. When encountering fire hazards, it can effectively prevent the spread of fire and ensure the safety of the device and personnel. The thickness of the conductive coating 8 coated on the surface of the box body 1 is 10 - 20 μm, and the resistivity ≤ 1×10 3Ω·cm. The presence of the conductive coating 8 endows the box body 1 with electromagnetic shielding function, which can effectively block the influence of external electromagnetic interference on the internal circuit module 2, ensuring the stable operation of the device in a complex electromagnetic environment. At the same time, it further enhances the fire safety, providing double protection for the stable operation of the device.

[0082] Specifically, the performance test process is as follows:

[0083] Drop test: The assembled standard terminal controller is freely dropped from a height of 1.5 meters onto a cement floor to simulate the possible drop situations in actual use. After 10 consecutive drop tests, a comprehensive inspection of the device is carried out. The results show that the device has no abnormal functions, and the internal circuit module and external interfaces are not damaged, fully verifying the excellent impact resistance performance of this product.

[0084] Environmental test: The device is placed in a freezing environment of -40°C for 24 hours, and then taken out to measure the hardness of the PU shock-absorbing rubber. At this time, the hardness of the PU shock-absorbing rubber is 32A (the initial value is 35A). Then, the device is placed in a heating environment of 80°C. After heating, it is observed that the PU shock-absorbing rubber has no fluidity, indicating that under extreme temperature environments, the PU rubber can still maintain good performance stability and meet the design requirements.

[0085] Maintenance test: A replacement test of the hollow shock-absorbing soft cover 3 and the hollow shock-absorbing soft cover 4 of the standard terminal controller is carried out, and the time required to replace the hollow shock-absorbing soft cover 3 and the hollow shock-absorbing soft cover 4 is recorded. The disassembly process mainly includes the following steps: First, hold the box body 1 of the controller with one hand, and gently press the connection part of the plug-in card block 13 on the hollow shock-absorbing soft cover 3 or the hollow shock-absorbing soft cover 4 with the thumb of the other hand; Second, while keeping the pressing, gently pull out the hollow shock-absorbing soft cover 3 or the hollow shock-absorbing soft cover 4 outward to completely separate the hollow shock-absorbing soft cover 3 or the hollow shock-absorbing soft cover 4 from the box body 1.

[0087] 1. Significantly improve the impact resistance performance, ensure that the internal components are not damaged when the device drops from a height of 1.5 meters, and effectively reduce the risk of device failure caused by dropping;

[0088] 2. Achieve lightweight design, with the overall weight reduced by 30%-40% compared to the traditional solution, meeting the development trend of equipment miniaturization and facilitating portability and operation;

[0089] 3. Broaden the temperature resistance range, expand the applicable temperature interval to -40°C to 80°C, and enhance the stability and reliability of the equipment under different ambient temperatures;

[0090] 4. Design a detachable shock-absorbing sleeve, support quick replacement, reduce maintenance costs, and extend the service life of the equipment.

[0091] In some embodiments, based on the standard terminal controller, some parameters are optimized and upgraded. Increase the wall thickness of the hollow shock-absorbing soft cover 3 or the hollow shock-absorbing soft cover 4 to 5 mm to further enhance the buffering effect. At the same time, adjust the density of the internally filled PU shock-absorbing glue to 1.2 g / cm 3 , further improve the buffering performance and compression resistance of the PU shock-absorbing glue. Improve the conductive coating 8 on the surface of the box body 1, increase the coating thickness to 20 μm, and make the resistivity ≤ 5×10 2 Ω·cm, thereby enhancing the electromagnetic shielding efficiency and better protecting the internal circuit from external electromagnetic interference.

[0092] Test results:

[0093] Drop test: Conduct a 2.0-meter drop test on the high-protection terminal controller. After multiple tests, the passing rate reaches 100%, indicating that after increasing the wall thickness of the hollow shock-absorbing soft cover 3 and the hollow shock-absorbing soft cover 4 and adjusting the density of the filled PU shock-absorbing glue, the impact resistance of the product has been further improved.

[0094] Electromagnetic shielding efficiency test: Conduct an electromagnetic shielding efficiency test on the high-protection terminal controller at a frequency of 1 GHz. The test results show that the electromagnetic shielding efficiency is increased to 40 dB, which is significantly improved compared to the standard terminal controller, effectively enhancing the stability of the equipment in a complex electromagnetic environment.
