Description

Technical Field

[0001] The present invention relates to the technical field of tire production, and in particular to a green tire quality detection device based on a tire production process. Background Art

[0002] The tire production process is a complex and delicate multi-process flow. First is the rubber mixing process, which precisely prepares various raw materials, fully fuses the materials through internal mixing, and then adjusts the properties of the rubber compound through open mixing. The extrusion process preheats the prepared rubber compound and extrudes it into specific-shaped parts. The calendering process applies rubber to the cord fabric and calenders the rubber film for use in constructing various parts of the tire. The semi-finished product manufacturing process includes operations such as cutting, wire processing, and pre-forming of parts to prepare for subsequent forming. The forming process precisely fits and compacts each semi-finished part in sequence on a forming machine to form a shape. Finally, the vulcanization process loads the green tire into a mold, where a vulcanization reaction occurs under high temperature and pressure, followed by post-treatment processes such as cooling, trimming, and inspection. Qualified products are packaged and stored in the warehouse, while unqualified ones are processed separately. Each process is closely linked and interdependent, jointly ensuring the high-quality production of tires.

[0003] In the current tire production process, the tires after production need to undergo strict detection of various data. Among them, durability detection is an extremely crucial part. At present, conventional tire durability detection covers important items such as high-speed performance testing, wear resistance testing, and fatigue resistance testing. However, these tests are usually carried out on different professional equipment separately, which results in the lack of comprehensive performance detection ability in the entire detection process. Due to the dispersion of the test process, the data used to evaluate the comprehensive performance of the tire often has some deviations, making it difficult to accurately and comprehensively reflect the true comprehensive performance of the tire, and thus unable to provide more accurate and reliable information basis for the further optimization and improvement of the tire and related applications. Especially for environmentally friendly green tires, the performance requirements are higher and the test items are more precise.

[0004] Therefore, a green tire quality detection device based on a tire production process is proposed. Therefore, it is necessary to propose a green tire quality detection device based on a tire production process to improve the quality detection accuracy of tires. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that the existing detection equipment has low quality detection accuracy for tires, and now a green tire quality detection device based on a tire production process is provided.

The detection wheel is located in the detection body and is rotatably connected to the detection body. A detection hole is provided on the operating table. The detection wheel passes through the detection hole and is arranged opposite to the inner tube. An air injection channel is provided in the detection wheel. An air branch channel connected to the air injection channel is provided on the wheel surface of the detection wheel. A raised spring grinding rod is provided in the air branch channel. An inflation chamber connected to the air injection channel and the inner tube is installed in the detection body, a piston plate is arranged in the inflation chamber, and the detection wheel is coaxially fixedly connected with the camshaft. During detection, the inner tube sleeve is provided with a tire, and the tire drives the detection wheel and the camshaft to rotate, and the camshaft drives the piston plate to move in the inflation chamber to thereby realize air injection into the inner tube and the air injection channel.

[0007] Furthermore, several strong spring connecting rods are fixed at equal intervals along a straight line on the piston plate, and one end of the strong spring connecting rod is in contact with the wheel surface of the camshaft. Due to the structural characteristics of the camshaft itself, when it rotates, the wheel surface of the camshaft will move the strong spring connecting rod that is always in contact with the wheel surface of the camshaft, causing the strong spring connecting rod to move back and forth, thereby driving the piston plate to move back and forth in the inflation chamber, thereby realizing the inflation of the inner tube and the air injection channel by the inflation chamber.

[0008] Furthermore, the telescopic bracket is composed of an electric push rod, several telescopic rods, a mounting seat connected to the surface of the detection body with bolts, and an assembly plate for fixing the inner tube. The electric push rod is used to provide power for pushing the assembly plate to move along the axis of the inner tube. The several telescopic rods are used to balance the force during movement to make the movement process more stable. The mounting seat is the base of the entire telescopic bracket, which is used to fix the electric push rod and the telescopic rod on the detection body. The assembly plate is usually arranged on both sides of the inner tube. When the tire to be tested is put on the inner tube, the assembly plate can fix the tire and the inner tube by bolts.

[0009] Furthermore, the telescopic bracket on one side of the inner tube is provided with two assembly plates, and the driving motor is located between the two assembly plates. Since the driving motor is installed on the telescopic bracket on this side, two assembly plates are configured; the electric push rod and several telescopic rods are located between the mounting seat and the assembly plate close to the mounting seat, and the driving motor is fixed on the assembly plate close to the mounting seat; the other assembly plate is fixedly mounted on the inner tube on this side, and the output shaft of the driving motor is plugged into the assembly plate on the inner tube on this side; when the electric push rod is extended or retracted, it can drive the assembly plate and the driving motor on the assembly plate to move, and when the driving motor rotates, it can drive the inner tube and the tire on the inner tube to rotate.

[0010] Furthermore, the telescopic bracket on the other side of the inner tube is provided with an assembly plate, the electric push rod and the telescopic rod are located between the assembly plate and the mounting seat, the assembly plate is fixedly mounted on the inner tube on this side, and when the electric push rod is extended or retracted, it can drive the assembly plate and the inner tube to move axially; an air pump connected to the inner tube is installed on the assembly plate, and when the inflation chamber inflates the inner tube, the air pump can conveniently detect the tire pressure of the inner tube and balance the tire pressure of the inner tube to stabilize the air pressure of the inner tube.

[0011] Furthermore, the strong spring connecting rod includes a limiting ring plate, a sliding rod and a spring mounted on the sliding rod and fixed to the limiting ring plate. The limiting ring plate is fixedly connected to the piston plate, one end of the sliding rod is in contact with the tire, and the spring limits and resets the sliding of the sliding rod inside the detection body. The sliding rod and the limiting ring plate are sleeved, and the sliding rod can slide relative to the limiting ring plate and the detection body. When the camshaft rotates, it will move one end of the sliding rod to make the sliding rod slide, and the spring can provide supporting elastic force for the sliding rod to reset the sliding rod, thereby realizing the reciprocating movement of the sliding rod, and then realizing the reciprocating movement of the piston plate in the inflation chamber, completing the inflation action of the inflation chamber.

[0012] Furthermore, a plurality of groups of air ducts are provided on the detection wheel along its axial direction, and the air ducts in the same group are arranged in a ring shape with the axis of the detection wheel as the center. In order to increase the friction, a plurality of raised spring grinding rods are provided on the detection wheel. Since the raised spring grinding rods are located in the air ducts, and whether the raised spring grinding rods protrude from the air ducts to the outside of the wheel surface of the detection wheel is controlled by the air pressure in the air ducts, the air ducts correspond to the raised spring grinding rods one by one. The distribution of such air ducts can effectively ensure the friction of the raised spring grinding rods when they protrude outside the wheel surface of the detection wheel, thereby facilitating the detection and testing of tire performance.

[0013] Furthermore, an air pressure passage is provided in the testing body, and the inflation chamber is connected with the air injection passage and the inner tube respectively through the air pressure passage. A one-way valve and a pressure relief valve for relieving pressure to the outside are installed in the air pressure passage. A one-way air exhaust passage is opened on the inner wall surface of the inflation chamber toward the outside of the testing body, and a one-way valve is installed inside the one-way air exhaust passage. The air pressure passage is used to inflate the inner tube and the air injection passage to test the degree of wear and wear resistance of the tire under different tire pressures and different friction forces of the testing wheel.

[0014] Furthermore, the air injection channel coincides with the axis of the detection wheel, and the air injection channel is arranged at the axis of the detection wheel to meet the structural design requirements and facilitate air intake; An interface communicating with the inner tube is provided at a position coincident with the axis of the inner tube. The inner tube is communicated with the air pressure passage through the interface. The interface is provided at the axis of the inner tube in accordance with the structural design requirements and is convenient for air intake.

[0015] Furthermore, one end of the sliding rod in contact with the tire is set as any one of a sphere, a cuboid, a prism, and an irregular body. The ends of the sliding rods with different shapes can provide different frictional forces for the tire, so that the detection wheel can simulate various road conditions in reality, such as rainy and snowy weather, gravel roads, and painted roads, for the tire, providing different frictional forces, and improving the detection accuracy and detection range of the detection equipment.

[0016] The beneficial effects of the present invention are as follows: 1. The present invention precisely controls the rotation of the camshaft through the precise change of the driving motor power, and further realizes the fine adjustment of the inner tube air pressure. It can extremely accurately simulate the tire pressure conditions of the tire under various actual driving states. Under these different tire pressure conditions, it can comprehensively detect various performances of the tire, deeply explore the influence laws of tire pressure on key performance indicators such as tire rolling resistance, grip, and handling stability, and provide scientific and detailed data support for the tire pressure optimization design; 2. The present invention effectively simulates the friction conditions under different road surface conditions by changing the interaction between the tire and the detection wheel. As the driving motor power changes, the tire rotation speed changes, and the frictional force between the tire and the detection wheel also changes accordingly, thereby prompting the gas to enter the detection wheel injection airway along a specific path, pushing up the convex spring grinding rod, and successfully simulating various working conditions such as the low-friction stable driving of the tire on a dry and flat road surface, the high-sliding resistance challenge on a wet and slippery road surface, and the high-wear test on a rough road surface. Under these conditions of simulating different road surface friction coefficients, it can comprehensively evaluate the wear resistance of the tire, including accurately measuring the change of the wear rate of the tire under different friction conditions, observing the uniform distribution of wear, and deeply analyzing the dynamic change of the grip retention ability of the tire in a complex friction environment, providing indispensable key data support for the tire material research and development, pattern innovation design, and overall structure optimization; The operation process of the device of the present invention is designed to be extremely simple and easy to understand. The staff only needs to perform a few basic operation steps to complete the entire detection process, without the need for the staff to perform cumbersome manual intervention. This highly automated operation mode greatly reduces the technical requirements for the operator. Even new employees can quickly get started and operate the equipment proficiently, effectively improving the work efficiency. At the same time, the detection speed of the equipment is extremely fast, and it can continuously complete the tire detection tasks under multiple complex working conditions in a short time, just like an efficient detection production line. It is especially suitable for the quality inspection link in the large-scale tire production process, can effectively guarantee the stability of product quality, significantly improve the production efficiency, reduce the production cost, and win advantages for the enterprise in the fierce market competition.

[0020] Embodiment 1: As Figure 1 and Figure 2 shown, this embodiment provides a green tire quality detection device based on tire production technology, including a detection main body 11. There is an operation table for tire detection on the detection main body 11. An inner tube 13 is arranged on the top of the operation table. The inner tube 13 is connected with a drive motor 121 that drives the inner tube 13 to rotate. Telescopic brackets 12 are arranged on both sides of the inner tube 13, and the telescopic brackets 12 drive the inner tube 13 to move axially. A detection wheel 14 is arranged at the bottom of the operation table.

The detection wheel 14 passes through the detection hole 143 and is arranged opposite to the inner tube 13. An air injection air duct 141 is arranged inside the detection wheel 14. Branch air ducts communicated with the air injection air duct 141 are opened on the wheel surface of the detection wheel 14. Convex spring grinding rods 142 are arranged in the branch air ducts. An air injection chamber 112 respectively communicated with the air injection air duct 141 and the inner tube 13 is installed inside the detection main body 11. A piston plate 152 is arranged inside the air injection chamber 112. The detection wheel 14 is coaxially and fixedly connected with a camshaft 15. During detection, a tire is sleeved on the inner tube 13, and the tire drives the detection wheel 14 and the camshaft 15 to rotate. The camshaft 15 drives the piston plate 152 to move inside the air injection chamber 112, thereby realizing air injection into the inner tube 13 and the air injection air duct 141.

[0021] Preferably, as Figure 1As shown, several strong spring connecting rods 151 are fixedly arranged on the piston plate 152 at equal intervals along a straight line. One end of the strong spring connecting rod 151 remains in contact with the wheel surface of the camshaft 15. Due to the structural characteristics of the camshaft 15 itself, when it rotates, the wheel surface of the camshaft 15 will push the strong spring connecting rod 151 that is always in contact with the wheel surface of the camshaft 15, causing the strong spring connecting rod 151 to move reciprocally, thereby driving the piston plate 152 to move reciprocally in the air charging chamber 112, and further realizing the inflation of the air charging chamber 112 into the inner tube 13 and the injection air passage 141.

[0022] Preferably, as Figure 2 shown, the telescopic support 12 is composed of an electric push rod 123, several telescopic rods 124, a mounting seat 125 connected to the surface of the detection main body 11 by a fitting bolt, and an assembly plate 122 for fixing the inner tube 13. The electric push rod 123 is used to provide power for pushing the assembly plate 122 to move along the axis of the inner tube 13. One end of the electric push rod 123 is fixedly connected to the mounting seat 125 by screws, and the other end is fixedly connected to the assembly plate 122. The several telescopic rods 124 are used to balance the force during movement to make the movement process more stable. The mounting seat 125 is the base of the entire telescopic support 12 and is used to fix the electric push rod 123 and the telescopic rods 124 on the detection main body 11. The mounting seat 125 is fixed on the detection main body 11 by screws. The assembly plate 122 is usually arranged on both sides of the inner tube 13. When the tire to be detected is sleeved on the inner tube 13, the assembly plate 122 can fix the tire and the inner tube 13 through bolts.

[0023] Preferably, as Figure 2 shown, for the telescopic support 12 on one side of the inner tube 13, the telescopic support 12 is provided with two assembly plates 122, and the driving motor 121 is located between the two assembly plates 122. Since the driving motor 121 is installed on the telescopic support 12 on this side, two assembly plates 122 are configured; the electric push rod 123 and several telescopic rods 124 are located between the mounting seat 125 and the assembly plate 122 close to the mounting seat 125, and the driving motor 121 is fixedly arranged on the assembly plate 122 close to the mounting seat 125; the other assembly plate 122 is fixedly installed on the inner tube 13 on this side, and the output shaft of the driving motor 121 is inserted into the assembly plate 122 on the inner tube 13 on this side; when the electric push rod 123 expands and contracts, it can drive the assembly plate 122 and the driving motor 121 on the assembly plate 122 to move, and when the driving motor 121 rotates, it can drive the inner tube 13 and the tire on the inner tube 13 to rotate.

[0024] Preferably, as Figure 2As shown, the telescopic bracket 12 on the other side of the inner tube 13 is provided with an assembly plate 122, and the electric push rod 123 and the telescopic rod 124 are located between the assembly plate 122 and the mounting seat 125. The assembly plate 122 is fixedly mounted on the inner tube 13 on this side. When the electric push rod 123 is extended or retracted, it can drive the assembly plate 122 and the inner tube 13 to move axially; an air pump 1221 connected to the inner tube 13 is installed on the assembly plate 122, and when the inflation chamber 112 inflates the inner tube 13, the air pump 1221 can conveniently detect the tire pressure of the inner tube 13, and balance the tire pressure of the inner tube 13 to stabilize the air pressure of the inner tube 13.

[0025] Preferably, Figure 3 As shown, the strong spring connecting rod 151 includes a limiting ring plate 1511, a sliding rod 1512 and a spring sleeved on the sliding rod 1512 and fixed to the limiting ring plate 1511. The limiting ring plate 1511 is fixedly connected with the piston plate 152 by screws. One end of the sliding rod 1512 contacts the tire. The spring limits and resets the sliding rod 1512 in the detection body 11. The sliding rod 1512 and the limiting ring plate 1511 are sleeved. The sliding rod 1512 can be moved in the limiting ring plate 1511. The plate 1511 slides inside, and the slide rod 1512 can slide relative to the limiting ring plate 1511 and the detection body 11. When the camshaft 15 rotates, it will push one end of the slide rod 1512 to make the slide rod 1512 slide, and the spring can provide supporting elastic force for the slide rod 1512 to reset the slide rod 1512, thereby realizing the reciprocating movement of the slide rod 1512, and then realizing the reciprocating movement of the piston plate 152 in the inflation chamber 112, completing the inflation action of the inflation chamber 112.

[0026] Preferably, Figure 2 As shown, the detection wheel 14 is provided with a plurality of groups of air ducts along its axial direction, and the air ducts in the same group are arranged in a ring shape with the axis of the detection wheel 14 as the center. In order to increase the friction, a plurality of raised spring grinding rods 142 are provided on the detection wheel 14. Since the raised spring grinding rods 142 are located in the air ducts, and whether the raised spring grinding rods 142 protrude from the air ducts to the outside of the wheel surface of the detection wheel 14 is controlled by the air pressure in the air ducts, the air ducts correspond to the raised spring grinding rods 142 one by one, and a raised spring grinding rod 142 is provided in each air duct. Such distribution of the air ducts can effectively ensure the friction of the raised spring grinding rods 142 when they protrude from the wheel surface of the detection wheel 14, so as to facilitate the detection and testing of tire performance.

[0027] Preferably, Figure 2As shown, a pneumatic airway 111 is provided inside the detection body 11. The air injection chamber 112 is respectively connected to the injection airway 141 and the inner tube 13 through the pneumatic airway 111. A one-way valve 1111 and a pressure relief valve for discharging pressure to the outside are installed and configured in the pneumatic airway 111. A through one-way air extraction airway 1121 is opened on the inner wall surface of the air injection chamber 112 towards the outside of the detection body 11, and a one-way valve 1111 is installed inside the one-way air extraction airway 1121. The pneumatic airway 111 is used to inflate the inner tube 13 and the injection airway 141, and test the wear degree and wear resistance of the tire under different tire pressures and different frictions of the detection wheel 14.

[0028] Preferably, the injection airway 141 coincides with the axis of the detection wheel 14. The injection airway 141 is arranged at the axis of the detection wheel 14 to meet the structural design requirements and facilitate air intake. An interface communicating with the inside of the inner tube 13 is opened at the position where the inner tube 13 coincides with its axis. The inner tube 13 is connected to the pneumatic airway 111 through the interface. The setting of the interface at the axis of the inner tube 13 meets the structural design requirements and facilitates air intake.

[0029] Preferably, one end of the sliding rod 1512 in contact with the tire is set as any one of a sphere, a cuboid, a prism, and an irregular body. The ends of the sliding rods 1512 with different shapes can provide different frictions for the tire, so that the detection wheel 14 can simulate various road conditions in reality for the tire, such as rainy and snowy weather, gravel roads, and painted roads, provide different frictions, and improve the detection accuracy and detection range of the detection device.

[0030] During operation, first pull back the right telescopic support 12 to disengage the drive motor 121's shaft from the plug-in drive state of the left mounting plate 122. Then, slip the tire to be tested over and fix it on the surface of the inner tube 13. After fixing, push the telescopic support 12 to reset the drive motor 121, so that the tire is positioned directly above and in contact with the inspection wheel 14. At this time, the drive motor 121 stops and is ready for inspection. During the inspection, first start the drive motor 121 with the primary power. The drive motor 121 drives the left mounting plate 122 to drive the tire to rotate. The tire drives the inspection wheel 14 and the camshaft 15 to rotate by means of the friction force with the inspection wheel 14. The convex surface of the camshaft 15 pushes the strong spring connecting rod 151 to drive the piston plate 152 to press down in the air pumping chamber 112. The gas is pressed into the inner tube 13 through the air pressure air duct 111 and the pipeline. The inner tube 13 expands to the preliminary air pressure. The air pump 1221 maintains the tire pressure according to the feedback of the air pressure sensor. Then, increase the power of the drive motor 121. The rotation speed of the tire increases, the camshaft 15 speeds up, the air pressure speed and air pressure in the air pumping chamber 112 increase. Part of the gas further expands the inner tube 13, and the other part meets the opening condition of the one-way valve 1111 and enters the air injection channel 141 of the inspection wheel 14, pressing against the convex spring grinding rod 142 to increase the friction coefficient between the tire and the inspection wheel 14. The staff cooperate with the instrument to observe and record. After running for the specified time, increase the power of the drive motor 121 again and record the data. After the inspection is completed, exhaust the gas in the air injection channel 141 through the exhaust air duct of the one-way valve 1111, and control the air pump 1221 to discharge the gas in the inner tube 13, then the next inspection can be carried out.

[0031] In summary, by precisely changing the power of the drive motor 121, the rotation of the camshaft 15 is accurately controlled, and then the air pressure of the inner tube 13 is finely adjusted, which can extremely accurately simulate the tire pressure working conditions under various actual driving states. Under these different tire pressure working conditions, various performances of the tire can be comprehensively detected, and the influence laws of tire pressure on key performance indicators such as tire rolling resistance, grip, and handling stability can be deeply explored, providing scientific and detailed data support for the tire pressure optimization design of the tire; by changing the interaction between the tire and the inspection wheel 14, the friction conditions under different road surface conditions are effectively simulated. As the power of the drive motor 121 changes, the rotation speed of the tire changes, and the friction force between the tire and the inspection wheel 14 also changes accordingly, which prompts the gas to enter the air injection channel 141 of the inspection wheel 14 along a specific path, pushing up the convex spring grinding rod 142, and successfully simulates various working conditions such as the low-friction stable driving of the tire on a dry and flat road surface, the high-slip resistance challenge on a wet and slippery road surface, and the high-wear test on a rough road surface. Under these conditions of simulating different road surface friction coefficients, the wear resistance performance of the tire can be comprehensively evaluated, including accurately measuring the change of the wear rate of the tire under different friction conditions, observing the uniform distribution of wear, and deeply analyzing the dynamic change of the grip retention ability of the tire in a complex friction environment, providing indispensable key data support for the material research and development, pattern innovation design, and overall structure optimization of the tire.

[0032] Working principle: During operation, first control the telescopic support 12 on the right to pull back the assembly plate 122, so that the shaft of the driving motor 121 is disengaged from the plug-in driving state with the left assembly plate 122. Then, place the tire to be detected and fix it on the surface of the inner tube 13. After the tire is fixed stably, control the telescopic support 12 to push the driving motor 121 to reset and adjust the position of the tire, so that the tire is directly above the detection wheel 14 and the surface of the tire contacts the surface of the detection wheel 14. At this time, the driving motor 121 is in a stopped state. Then, the detection of the tire can be carried out;When detecting a tire, first control the driving motor 121 to start with a primary power. Then, the driving motor 121 drives the left mounting plate 122, causing the left mounting plate 122 to drive the tire to rotate. The rotating mounting plate 122 drives the tire being detected to rotate the detection wheel 14 by means of the frictional force between them. At the same time, since one end of the camshaft 15 is fixed to the rotating shaft of the detection wheel 14, the rotation of the tire also drives the camshaft 15 to rotate synchronously. The cam surface of the camshaft 15 is in movable contact with the spherical part at the upper end of the strong spring link 151. As the camshaft 15 rotates, the protruding part of its cam surface periodically pushes the strong spring link 151 downward, and the strong spring link 151 drives the piston plate 152 to slide downward in the air pumping chamber 112, causing the gas in the air pumping chamber 112 to be pressed into the inner tube 13 through the air pressure airway 111 and the pipeline, expanding the inner tube 13 to a preliminary air pressure state. After the air pressure inside the inner tube 13 reaches the specified parameters, the air pump 1221 dynamically pumps and discharges the gas inside the inner tube 13 according to the data fed back by the air pressure sensor, maintaining the air pressure inside the inner tube 13 at the preliminary tire pressure state all the time. At this time, the staff can cooperate with the external instrument to observe and record the state of the tire, and then control the driving motor 121 to increase its power, so that the driving motor 121 increases the rotational driving speed of the tire. The accelerating tire further compresses on the surface of the detection wheel 14, driving the detection wheel 14 and the camshaft 15 to further speed up. The accelerating camshaft 15 increases the speed of pushing the piston plate 152 downward. Since the reciprocating speed of the piston plate 152 increases, the air compression speed inside the air pumping chamber 112 becomes faster, and the air pressure during compression increases. Then, a part of the compressed gas preferentially enters the inner tube 13 through the air pressure airway 111, further expanding the inner tube 13 and increasing the tire pressure inside. After the tire pressure reaches the specified value, the air pump 1221 actively pumps out the gas inside the inner tube 13, keeping the air pressure inside the inner tube 13 stable within the specified air pressure range. Another part of the gas meets the opening condition of the one-way valve 1111, enters the injection airway 141 inside the detection wheel 14 along the air pressure airway 111, and presses against the piston end of the protruding spring grinding rod 142 along the detection wheel 14. While compressing the spring of the protruding spring grinding rod 142, it pushes the protruding spring grinding rod 142 in the centrifugal direction. Then, the centrifugal end of the protruding spring grinding rod 142 moves out of the detection wheel 14, increasing the friction coefficient between the tire and the detection wheel 14. Then, the staff can cooperate with the external instrument to observe and record the state of the tire. After running for the specified time, control the driving motor 121 to increase its operating power again and record the data at this power. After the detection is completed, the injection airway 141 can be exhausted through the exhaust airway of the air pressure airway 111 where the one-way valve 1111 is set. At the same time, the air pump 1221 can be controlled to exhaust the gas inside the inner tube 13, and thus the next detection operation can be carried out.;

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made to the content within the scope of the patent application of the present invention shall fall within the technical scope of the present invention.
