Description

Technical Field

[0001] The present invention relates to the technical field of intelligent forklift control systems, and in particular to a protective structure of an intelligent forklift control system. Background Art

[0002] In modern logistics and industrial production, forklifts have been widely used as important handling equipment. With the continuous advancement of science and technology, intelligent forklifts have come into being. The control system of intelligent forklifts integrates advanced sensor technology, automatic control algorithms and data communication modules to achieve functions such as autonomous navigation, cargo identification and precise handling. The stability and reliability of its control system plays a vital role in the normal operation and operational safety of the entire forklift.

[0003] However, existing intelligent forklifts will inevitably generate vibrations during operation, which can easily damage key components such as the power controller in the control system, reduce their service life and may cause failures, affecting the precise control and operating efficiency of the forklift. Moreover, the operating environment of the forklift is usually more complex, and dust, impurities, etc. can easily enter the control system. In particular, once the heat dissipation holes are blocked, the power controller will not dissipate heat smoothly and heat will accumulate, further affecting its performance and even causing overheating damage.

[0004] In view of this, research and improvements are conducted on the existing problems, and a protective structure for an intelligent forklift control system is provided, which can effectively solve problems such as vibration buffering, heat dissipation and dust prevention, and efficient heat dissipation, so as to improve the overall performance and reliability of the intelligent forklift control system, ensure its stable operation under complex working conditions and extend its service life.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The shock absorbing mechanism provided in the present invention can effectively protect the power controller and reduce vibration damage. When the forklift vibrates, the lower protective shell drives the rotating rod to rotate, and the buffer spring offsets the force to prevent the shock absorber from being over-compressed, thereby extending its service life and protecting the power controller.

[0021] 2. The present invention utilizes that while the shock absorbing mechanism is working, the slide seat drives the connecting plate to move, thereby causing the push rod to drive the upper protective shell to slide up and down, and synchronously drives the pressure plate. When the pressure plate rises, it will compress the airbag, so that the air in the airbag is discharged from the nozzle through the air pipe A. The air sprayed from the nozzle is convenient for blowing out the dust in the heat dissipation hole B, thereby avoiding the heat dissipation being blocked by dust in the heat dissipation hole B. At the same time, the nozzle not only cleans the dust, but also assists in discharging the heat from the heat dissipation holes A and B to the outside world, thereby further improving the heat dissipation efficiency.

[0022] 3. When the heat generated by the power controller increases, the heat dissipation effect of the heat dissipation holes A and B is poor, and the temperature in the lower protective shell reaches a threshold, the memory metal undergoes physical deformation due to the change in the crystal structure caused by heat, and controls the opening and closing of the movable plug and the connecting sleeve. When opened, the pressure plate rises to compress the airbag, and the gas enters the sleeve through the gas pipe B, thereby increasing its pressure to push the circular plate, the connecting rod, and the piston, allowing the coolant to flow into the cooling pipe to take away the heat, thereby improving the heat dissipation efficiency. At the same time, under the action of the sleeve reset spring, the piston moves in the opposite direction, and the coolant in the sealed cavity is compressed, and circulates through the through hole, thereby achieving the purpose of efficient heat dissipation.

[0023] 4. In the present invention, when the air pressure inside the sleeve reaches a preset intensity, the solenoid valve senses and opens to release the pressure. Under the action of the reset spring, the circular plate presses down the compressed gas, which enters the air pipe A through the solenoid valve and the connecting pipe, thereby increasing its air pressure. After the air pressure in the air pipe A is enhanced, the jet intensity of the nozzle is improved, which can more effectively remove dust in the heat dissipation hole B, prevent dust accumulation from affecting heat dissipation, and thus keep the heat dissipation hole unobstructed, thereby improving the heat dissipation efficiency of the entire system.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The present invention provides a protection structure of an intelligent forklift control system, comprising a forklift body 1, a base 2 is fixedly installed inside the forklift body 1, a lower protective shell 3 is slidably connected inside the base 2, an upper protective shell 4 is slidably sleeved on the top of the lower protective shell 3, a power controller 5 is detachably installed at the bottom end of the lower protective shell 3, a shock absorbing mechanism 6 is arranged inside the base 2, heat dissipation holes A7 are opened on both sides of the lower protective shell 3, heat dissipation holes B8 are opened on both sides of the upper protective shell 4, a heat dissipation mechanism 12 is arranged inside the lower protective shell 3, and a cooling mechanism 14 is arranged inside the lower protective shell 3;

[0036] See also Figures 1 to 3As shown, the shock absorbing mechanism 6 includes two groups of slide bars 601, which are fixedly connected to the inner wall of the base 2, and the outer walls of the two groups of slide bars 601 are slidably sleeved with two groups of slide seats 602, and the outer walls of both ends of the slide bars 601 are sleeved with buffer springs 603, and the bottom of the lower protective shell 3 is fixedly connected with two groups of fixed seats 604, and the slide seats 602 are rotatably connected to the fixed seats 604 on the corresponding side through a rotating rod 605, and the two ends of the base 2 are slidably connected with a top rod 606, and the inside of the base 2 is symmetrically installed with two groups of shock absorbers 609. When the forklift body 1 is driving, the shock absorbing device 609 is symmetrically installed. The mechanism 6 can play a role in damping and buffering the power controller 5. When the forklift body 1 vibrates, the downward movement distance of the lower protective shell 3 becomes longer. During the downward movement of the lower protective shell 3, the rotating rod 605 is driven to rotate. When the downward movement distance exceeds a certain range, the slide seat 602 contacts the buffer spring 603, so that the multiple buffer springs 603 can offset part of the force, which can avoid the compression range of the shock absorber 609 being too large to cause damage to the shock absorber 609, thereby extending the service life of the shock absorber 609, and further playing a certain protective role for the power controller 5;

[0037] See also Figures 4 to 6 As shown, the heat dissipation mechanism 12 includes an airbag 1201, which is fixedly mounted on the inner top of the upper protective shell 4, a support rod 1202 is rotatably connected to the top of the lower protective shell 3, a pressure plate 1203 is fixedly connected to the top of the support rod 1202, mounting frames 1204 are fixedly connected to both sides of the inner wall of the lower protective shell 3, a bracket 1205 is fixedly connected to the inside of the mounting frame 1204, a nozzle 1206 is rotatably connected to the inside of the bracket 1205 through a torsion spring, the airbag 1201 and the nozzle 1206 are fixedly connected through an air pipe A1207, and a one-way valve is installed at the connection between the air pipe A1207 and the airbag 1201, the bottom of the airbag 1201 is fixedly connected to a ventilation duct, and a temperature control switch 13 is arranged on one side of the ventilation duct. When the shock absorbing mechanism 6 is working, The slide 602 drives the connecting plate 607 to move synchronously, so that the connecting plate 607 drives the connecting rod 608 to rotate, so that the connecting rod 608 drives the push rod 606 to move up and down, and the push rod 606 drives the upper protective shell 4 to slide up and down on the outer surface of the lower protective shell 3. When the upper protective shell 4 slides up and down, it can synchronously drive the pressing plate 1203 to move. When the pressing plate 1203 rises, it will compress the airbag 1201, so that the air in the airbag 1201 is discharged from the nozzle 1206 through the air pipe A1207. The air ejected from the nozzle 1206 is convenient for blowing out the dust in the heat dissipation hole B8, avoiding the heat dissipation being blocked by dust in the heat dissipation hole B8. At the same time, the nozzle 1206 not only cleans the dust, but also helps to discharge the heat from the heat dissipation holes A7 and the heat dissipation holes B8 to the outside, thereby further improving the heat dissipation efficiency;

[0038] See also Figures 4 to 8As shown, the cooling mechanism 14 includes a liquid storage tank 1401, both ends of the liquid storage tank 1401 are fixedly connected with cooling pipes 1402, the outer wall of the cooling pipe 1402 is provided with a slide groove 1403, the interior of the slide groove 1403 is slidably connected with a sealing plate 1404, the interior of the liquid storage tank 1401 is slidably connected with a piston 1405, one side of the piston 1405 is hinged with a baffle 1406, one side of the liquid storage tank 1401 is fixedly connected with a sleeve 1407, the interior of the sleeve 1407 is slidably connected with a circular plate 1408, the top of the circular plate 1408 is fixedly connected with a connecting rod 1409, and the connecting rod 1409 passes through one side of the sleeve 1407. The end is fixedly connected to the sealing plate 1404. When the heat generated by the power controller 5 increases, the heat dissipation holes A7 and the heat dissipation holes B8 cannot be effectively dissipated. Therefore, when the temperature inside the lower protective shell 3 reaches a certain threshold, the crystal structure inside the memory metal 1304 will change, resulting in a change in its appearance, so that the memory metal 1304 undergoes physical deformation when the heat changes frequently, and the active plug 1303 and the connecting sleeve 1302 are closed and opened. When the active plug 1303 and the connecting sleeve 1302 are in the open state, the pressure plate 1203 rises to compress the airbag 1201, so that the airbag 120 A portion of the gas of 1 enters the interior of the sleeve 1407 through the gas delivery pipe B1305, increasing the internal pressure of the sleeve 1407, so that the gas pushes the circular plate 1408 to move upward, and the circular plate 1408 synchronously drives the connecting rod 1409 to move, and the connecting rod 1409 drives the piston 1405 to move, so that the piston 1405 moves toward the top of the liquid storage tank 1401, so that the space of the sealed cavity formed by the piston 1405 and the top of the liquid storage tank 1401 is reduced, so that the coolant on the top of the piston 1405 is squeezed into the cooling pipe 1402, so that the coolant in the cooling pipe 1402 starts to flow, and the flowing coolant brings The heat of the power controller 5 is taken away to achieve a better heat effect and improve the heat dissipation efficiency. In addition, under the pulling force of the reset spring 1410 in the sleeve 1407, the reset spring 1410 drives the connecting rod 1409 to move in the opposite direction, and the connecting rod 1409 drives the piston 1405 to move in the opposite direction synchronously, thereby reducing the sealed cavity space at the bottom of the piston 1405, and the coolant in the sealed cavity is compressed. The thrust of the coolant on the baffle 1406 is greater than the restoring force of the torsion spring inside the baffle 1406. At this time, the coolant will be squeezed into the sealed cavity at the top of the piston 1405 through the through hole, thereby realizing the circulation of the coolant and achieving efficient heat dissipation.

[0039] In addition, when the air pressure inside the sleeve 1407 reaches a preset intensity, the solenoid valve will sense the need to release pressure, thereby ensuring the normal operation of the cooling mechanism 14. Under the elastic potential energy of the return spring 1410, the return spring 1410 pushes the circular plate 1408 downward to compress the gas inside the sleeve 1407. The compressed gas is guided into the connecting pipe 15 through the solenoid valve. The solenoid valve automatically opens when the air pressure reaches a certain intensity to ensure that the gas can flow smoothly. The connecting pipe 15 transports the compressed gas from the sleeve 1407 to As the gas transported by the connecting pipe 15 enters the gas pipe A1207, the air pressure inside the gas pipe A1207 increases. The increase in the air pressure in the gas pipe A1207 causes the jet intensity of the nozzle 1206 to be enhanced. The enhanced jet intensity of the nozzle 1206 helps to more effectively remove the dust in the heat dissipation hole B8 and prevent dust accumulation from causing a decrease in heat dissipation efficiency. By enhancing the jet intensity of the nozzle 1206, the dust inside the heat dissipation hole B8 can be more effectively ejected, keeping the heat dissipation hole unobstructed, thereby improving the heat dissipation efficiency of the entire system.

[0040] See also Figure 3 As shown, a connecting plate 607 is fixedly connected between the two groups of slides 602, and the connecting plate 607 is connected to the top rod 606 on the corresponding side through a connecting rod 608, and the two ends of the connecting rod 608 are respectively hinged to the top rod 606 and the connecting plate 607, so that the top rod 606 and the connecting plate 607 can rotate relative to each other, thereby driving the top rod 606 to move.

[0041] See also Figure 6 As shown, there are multiple groups of heat dissipation holes A7 and heat dissipation holes B8, and the multiple groups of heat dissipation holes A7 and heat dissipation holes B8 are staggered. The staggered heat dissipation holes A7 and heat dissipation holes B8 can reduce the chance of dust and other foreign matter directly entering the interior of the forklift, which helps to protect the internal components from pollution and damage.

[0042] See also Figure 6 As shown, the outer wall of the upper protective shell 4 is fixedly connected to an air outlet pipe 9, one end of the air outlet pipe 9 is fixedly connected to a filter screen 10, and the outer wall of the air outlet pipe 9 is provided with multiple groups of exhaust holes 11 with equal intervals. The design of multiple groups of exhaust holes 11 can increase the air flow channel, improve the air flow efficiency, and enable hot air to be discharged faster. The gas discharged from the exhaust holes 11 can clean the dust on the outside of the upper protective shell 4, reducing the need for manual cleaning and keeping the appearance of the upper protective shell 4 neat.

[0043] See also Figure 7As shown, the temperature control switch 13 includes a shell 1301, which is fixedly connected to one side of the first pipeline. A connecting sleeve 1302 is fixedly connected to the inside of the shell 1301, and a movable plug 1303 is slidably connected to the inside of the connecting sleeve 1302. The shell 1301 is fixedly connected to the sleeve 1407 through the gas supply pipe B1305. The automatic closing of the temperature control switch 13 can control the gas delivery operation, thereby improving the stability, reliability and energy efficiency of the system.

[0044] See also Figure 7 As shown, the temperature control switch 13 also includes a memory metal 1304, which is fixedly connected to one end of the movable plug 1303. The memory metal 1304 is made of nickel-titanium alloy material. The automatic adjustment function of the memory metal 1304 reduces the need for manual intervention and improves the system's automation level and operational convenience.

[0045] See also Figure 8 As shown, a through hole is opened on the surface of the piston 1405, and the piston 1405 is arranged corresponding to the through hole. The arrangement of the through hole helps the circulation of the coolant.

[0046] See also Figure 8 As shown, a return spring 1410 is disposed inside the sleeve 1407, one end of the return spring 1410 is fixedly connected to the circular plate 1408, and the other end of the return spring 1410 is fixedly connected to the inner wall of the sleeve 1407, so that the circular plate 1408 can automatically return to its initial position.

[0047] See also Figure 8 As shown, the cooling pipe 1402 is spirally arranged on the periphery of the power controller 5, which can more effectively transfer and dissipate the heat generated by the power controller 5 and improve the cooling efficiency. A one-way valve is fixedly installed at the connection between the liquid storage tank 1401 and the cooling pipe 1402. The function of the one-way valve is to prevent the coolant from flowing in the opposite direction and ensure that the coolant can only flow in one direction.

[0048] See also Figure 8 As shown, the outer wall of the sleeve 1407 is fixedly connected to the connecting pipe 15, and a one-way valve is fixedly installed at the connecting port of the sleeve 1407 and the connecting pipe 15. The one-way valve can prevent gas backflow and ensure normal gas transportation.

[0049] Working principle: When the forklift body 1 is in motion, the shock absorbing mechanism 6 can play a role in damping and buffering the power controller 5. When the forklift body 1 vibrates, the downward movement distance of the lower protective shell 3 becomes longer. During the downward movement of the lower protective shell 3, the rotating rod 605 is driven to rotate. When the downward movement distance exceeds a certain range, the slide seat 602 contacts the buffer spring 603, so that the multiple buffer springs 603 can offset part of the force, which can avoid the compression range of the shock absorber 609 being too large to cause damage to the shock absorber 609, thereby extending the service life of the shock absorber 609, and further playing a certain protective role for the power controller 5;

[0050] When the shock absorbing mechanism 6 is working, the sliding seat 602 drives the connecting plate 607 to move synchronously, so that the connecting plate 607 drives the connecting rod 608 to rotate, so that the connecting rod 608 drives the top rod 606 to move up and down, and the top rod 606 drives the upper protective shell 4 to slide up and down on the outer surface of the lower protective shell 3. When the upper protective shell 4 slides up and down, it can synchronously drive the pressing plate 1203 to move. When the pressing plate 1203 rises, it will compress the airbag 1201, so that the air in the airbag 1201 is discharged from the nozzle 1206 through the air pipe A1207. The air ejected from the nozzle 1206 is convenient for blowing out the dust in the heat dissipation hole B8, avoiding the heat dissipation being blocked by dust in the heat dissipation hole B8. At the same time, the nozzle 1206 not only cleans the dust, but also helps to discharge the heat from the heat dissipation holes A7 and the heat dissipation holes B8 to the outside, so as to further improve the heat dissipation efficiency;

[0051] When the heat generated by the power controller 5 increases, the heat dissipation holes A7 and B8 cannot effectively dissipate the heat. Therefore, when the temperature inside the lower protective shell 3 reaches a certain threshold, the crystal structure inside the memory metal 1304 will change, resulting in a change in its appearance, so that the memory metal 1304 undergoes physical deformation when the heat changes frequently, thereby realizing the closing and opening of the movable plug 1303 and the connecting sleeve 1302. When the movable plug 1303 and the connecting sleeve 1302 are in the open state, the pressure plate 1203 rises and compresses the airbag 1201, so that part of the gas in the airbag 1201 enters the interior of the sleeve 1407 through the gas pipe B1305, thereby increasing the internal pressure of the sleeve 1407, so that the gas pushes the circular plate 1408 to move upward, and the circular plate 1408 synchronously drives the connecting rod 1409 to move, and the connecting rod 1409 drives the piston 1405 to move, so that the piston 1405 moves The top of the liquid storage tank 1401 moves, thereby reducing the sealed cavity space formed by the piston 1405 and the top of the liquid storage tank 1401, so that the coolant on the top of the piston 1405 squeezes into the cooling tube 1402, so that the coolant in the cooling tube 1402 starts to flow, and the flowing coolant takes away the heat of the power supply controller 5, achieving a better heat effect and improving the heat dissipation efficiency. In addition, under the pulling force of the return spring 1410 in the sleeve 1407, the return spring 1410 drives the connecting rod 1409 to move in the opposite direction, and the connecting rod 1409 drives the piston 1405 to move in the opposite direction synchronously, thereby reducing the sealed cavity space at the bottom of the piston 1405, and the coolant in the sealed cavity is compressed. The thrust of the coolant on the baffle 1406 is greater than the restoring force of the torsion spring inside the baffle 1406. At this time, the coolant will squeeze into the sealed cavity at the top of the piston 1405 through the through hole, thereby realizing the circulation of the coolant and achieving efficient heat dissipation.

[0052] In addition, when the air pressure inside the sleeve 1407 reaches a preset intensity, the solenoid valve will sense the need to release pressure, thereby ensuring the normal operation of the cooling mechanism 14. Under the elastic potential energy of the return spring 1410, the return spring 1410 pushes the circular plate 1408 downward to compress the gas inside the sleeve 1407. The compressed gas is guided into the connecting pipe 15 through the solenoid valve. The solenoid valve automatically opens when the air pressure reaches a certain intensity to ensure that the gas can flow smoothly. The connecting pipe 15 transports the compressed gas from the sleeve 1407 to As the gas transported by the connecting pipe 15 enters the gas pipe A1207, the air pressure inside the gas pipe A1207 increases. The increase in the air pressure in the gas pipe A1207 causes the jet intensity of the nozzle 1206 to be enhanced. The enhanced jet intensity of the nozzle 1206 helps to more effectively remove the dust in the heat dissipation hole B8 and prevent dust accumulation from causing a decrease in heat dissipation efficiency. By enhancing the jet intensity of the nozzle 1206, the dust inside the heat dissipation hole B8 can be more effectively ejected, keeping the heat dissipation hole unobstructed, thereby improving the heat dissipation efficiency of the entire system.
