Description

Technical Field

[0001] This invention relates to the field of polishing equipment technology, specifically to a polishing device and process for the backrest support of a 4D platform seat. Background Technology

[0002] The 4D platform seat is an immersive seat that integrates dynamic motion feedback and environmental effects simulation. It mainly consists of a motion platform, seat surface, armrests, upholstery materials, vibrators, backrest support and other components.

[0003] As a core component of immersive experience equipment, the 4D platform seat's backrest support not only needs to withstand the structural strength under the dynamic impact of passengers, but also needs to fit closely to the human back. If its surface roughness is too high, it will cause wear and tear on passengers' clothes or skin discomfort. Therefore, in order to solve this problem, the backrest support of the 4D platform seat needs to be polished with a polishing device during production to reduce its roughness.

[0004] While existing ultrasonic polishing devices can polish the backrest support of 4D platform seats in practical use, ensuring that the manufactured 4D platform seats fit snugly against the human back and improving passenger comfort, they still have the following shortcomings: When processing the backrest support of the 4D platform seat, the stirring mechanism for the abrasive suspension and the cooling mechanism responsible for heat dissipation of the abrasive suspension are mostly independent of each other, and each needs to be equipped with an independent power source. Although this design can ensure uniform sedimentation and rapid cooling of the abrasive suspension, the overall structure of the equipment is complex, which not only increases the complexity of the connection of pipelines and circuits, but also makes the device occupy a large space.

[0005] Therefore, we propose a new polishing device and process for the backrest support of a 4D platform seat to solve the problems mentioned above. Summary of the Invention

[0016] A process for polishing a backrest support device for a 4D platform seat includes the following steps: S1. When polishing the backrest support of the 4D platform seat is required, first use the cooperation of two sliding grooves and two clamps to squeeze and fix the backrest support placed at the bottom of the inner wall of the housing. Then, use the cooperation of the ultrasonic generator, the interface, plug, cable, housing, tool head, amplitude rod, transducer and abrasive suspension to polish the backrest support. At the same time, use the cooperation of the hand screw, limit block, diverter tube, perforated block and the other of the two pre-set threaded grooves on the connecting tube to fix the connecting tube after it has moved. S2. Then, by using the combination of a fan, controller, storage box, perforated cover, two connecting pipes, connecting pipe, one of the air ducts of the diversion pipe, two U-shaped pipes, two one-way valves and two multi-hole air outlet pipes, air from the environment is drawn in and delivered to the abrasive suspension inside the shell to stir the abrasive suspension. S3. After completing the polishing operation of the first backrest bracket, and determining, through the temperature sensor and the pre-set temperature range threshold, that the suspension inside the shell needs to be cooled, return the connecting pipe to its original position and fix it in place. At the same time, put ice cubes into the storage box. Then, using the cooled air, the connecting pipe, another air duct of the split pipe, the split shell, all heat sinks, the auxiliary shell, and the rectangular hole, and using the principle of heat transfer, the abrasive suspension inside the shell can be cooled down quickly. Once the temperature drops to the initial temperature, repeat the above steps to perform the polishing operation of the second backrest bracket.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting an auxiliary mechanism, combines the stirring mechanism for the abrasive suspension with the cooling mechanism responsible for heat dissipation of the abrasive suspension, and also reduces the number of power sources and the space occupied by the device, thereby improving the efficiency of the polishing device. When the backrest bracket starts polishing, the connecting pipe is fixed after being moved by first using the hand-tightening screw, the limiting block, the diverter pipe, the perforated block, and the other of the two pre-set threaded grooves on the connecting pipe. Then, by using the fan, controller, storage box, perforated cover, two connecting pipes, and one of the air ducts of the connecting pipe and the diverter pipe, air from the environment can be drawn in and diverted to the inside of the two U-shaped pipes. Then, by using the two U-shaped pipes, two one-way valves, and two multi-hole air outlet pipes, air can be delivered to the abrasive suspension inside the shell, stirring the abrasive suspension and dispersing the abrasive in the suspension evenly, avoiding local over-polishing.

[0018] 2. When the polishing operation of the first backrest bracket is completed, and the temperature sensor and the pre-set temperature range threshold are used to determine that the suspension inside the shell needs to be cooled, the connecting pipe is first reset to its original position and fixed. At the same time, ice is put into the storage box. Then, by using the cooling air, the connecting pipe, another air duct of the split pipe, the split shell, all heat sinks, the auxiliary shell and the rectangular hole, the abrasive suspension inside the shell can be quickly cooled by using the principle of heat transfer.

[0019] 3. This invention, by setting up a polishing mechanism, can polish the backrest support of the 4D platform seat, thereby ensuring that the manufactured 4D platform seat can fit closely to the human back, thus improving the comfort of passengers using the 4D platform seat. When it is necessary to polish the backrest support of the 4D platform seat, the backrest support placed at the bottom of the inner wall of the shell can be squeezed and fixed by the cooperation of two sliding grooves and two clamps.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figures 1-7 and Figure 12 As shown, the present invention provides a technical solution: a polishing device for the backrest support of a 4D platform seat, including a polishing mechanism 1. The polishing mechanism 1 is used to polish the backrest support. The polishing mechanism 1 includes a housing 101, a base plate 102 is installed on the top of the housing 101, an ultrasonic generator 103 is placed in the groove at the top of the housing 101, a buffer sleeve 104 is bonded inside the through hole at the top of the housing 101, and a shell 105 is provided inside the buffer sleeve 104. Slide grooves 106 are preset on the front surface and the rear surface of the housing 101 near the top. A set of clamps 107 is provided between the interior of the two slide grooves 106. A U-shaped block 108 is fixed to the top of the inner wall of the housing 101. A drawer 109 is provided inside the U-shaped block 108. The drawer 109 is movably fitted into the through hole on the front surface of the housing 101. A storage box 1 is fixed to the top of the inner wall of the drawer 109. 10. A housing 111 is placed in the groove at the top of the box 110. Inside the housing 111, there is a tool head 112, an amplitude transformer 113, and a transducer 114. The tool head 112 is threaded to the amplitude transformer 113, and the amplitude transformer 113 is threaded to the transducer 114. A cable 115 is movably passed through the cap surface of the housing 111. One end of the cable 115 is connected to the terminal of the transducer 114, and the other end of the cable 115 is connected to a plug 116. Both the cable 115 and the plug 116 are inside the drawer 109. The plug 116 is compatible with the interface on the ultrasonic generator 103. A plug 117 is provided at the bottom drain inlet of the housing 105. The bottom drain of the housing 105 is connected to a drain pipe 118. The outlet of the drain pipe 118 movably passes through the rear surface of the inner wall of the box 101. A cushioning pad 3 is glued to the bottom of each support leg of the base plate 102.

[0024] In this embodiment, when polishing the backrest support of the 4D platform seat is required, the backrest support is first moved to the bottom of the inner wall of the housing 105. Then, the two clamps 107 are moved sequentially between the two slide grooves 106. Once the two clamps 107 are in position, they are fixed between the two slide grooves 106. The backrest support at the bottom of the inner wall of the housing 105 is then fixed using the two clamps 107. Next, an appropriate amount of abrasive suspension (enough to submerge the backrest support) is poured into the housing 105. The operator holds the outer casing 111 and moves the tool head 112, amplitude transformer 113, and transducer 114 simultaneously. When the tool head 112 is above the casing 105, it is upright, pointing vertically downwards. Then, the ultrasonic generator 103 is activated. The activated ultrasonic generator 103 converts mains power into a high-frequency electrical signal. This high-frequency signal is then transmitted to the transducer 114 via its interface, plug 116, and cable 115. Upon receiving the high-frequency signal, the transducer 114... The signal is converted into mechanical vibration, which is then amplified by the amplitude transformer 113. The high-frequency vibration is then transmitted to the tool head 112. The tool head 112 is then vertically moved into the abrasive suspension inside the housing 105, with its bottom approaching the top of the backrest support but not touching it (the distance between them depends on the actual situation). When the tool head 112 completes its positional movement, its vibration causes the surrounding abrasive suspension to impact the surface of the backrest support at high speed, thus purifying the surface of the backrest support. Micro-cutting and grinding remove surface peaks. At the same time, the vibration of the tool head 112 causes tiny bubbles to continuously form in the abrasive suspension. These bubbles burst instantly under high pressure, generating local shock waves and micro-jet streams, which further scour the surface of the backrest bracket, accelerating the removal of surface impurities and tiny protrusions. After all the backrest bracket polishing operations are completed and the abrasive suspension returns to its initial temperature, all previously activated components are turned off. Then, the plug 117 is removed from the drain inlet of the housing 105, allowing the abrasive suspension inside the housing 105 to be drained away through the drain pipe 118.

[0025] Example 2: According to Figures 1-3 and Figures 5-12As shown, the polishing mechanism 1 is equipped with an auxiliary mechanism 2. The auxiliary mechanism 2 is used to stir the abrasive suspension and assist in the rapid reduction of the abrasive suspension. The auxiliary mechanism 2 includes a storage box 201, a controller 203, a fan 204, a diversion pipe 210, a rectangular hole 215, and a temperature sensor 218. The air inlet and outlet of the fan 204 are both connected to a connecting pipe 217. The air outlet of one of the connecting pipes 217 is connected to a connecting pipe 212. Each air outlet of one of the air ducts of the diversion pipe 210 is connected to a U-shaped pipe 207. The air outlet of each U-shaped pipe 207 is connected to a one-way valve 206. The air outlet of each one-way valve 206 is connected to a multi-hole air outlet pipe 205, and each multi-hole air outlet pipe 205 is a single-opening type. One end of the diversion pipe 210 is fixed. The system includes a distribution shell 208, with heat sinks 209 inside each air duct. An auxiliary shell 214 is fixed between the multiple air outlets of the distribution shell 208. A perforated cover 202 is placed at the top opening of the storage box 201. The air inlet of the distribution shell 208 is connected to another air duct of the distribution pipe 210. A connecting pipe 212 controls whether the delivered gas is sent to one or the other air duct of the distribution pipe 210. A limiting block 211 is provided around the connecting pipe 212, and a perforated block 213 is placed near the edge of the top of the connecting pipe 212. The interior of the auxiliary shell 214 is connected to the interior of a rectangular hole 215. A hand-tightening screw 216 is located inside the perforated block 213. The threaded end of the hand-tightening screw 216 is threadedly connected to one of the two pre-set threaded grooves on the connecting pipe 212. The air inlet end of the other connecting pipe 217 is connected to the air outlet end of the storage box 201. The polishing mechanism 1 includes a housing 101. The storage box 201 is fixedly inserted through the inner wall surface of the housing 101. The controller 203 is installed on the inner wall surface of the housing 101. The control end of the controller 203 moves through the inner wall surface of the housing 101. A base plate 102 is installed on the top of the housing 101. A fan 204 is installed on the top of the base plate 102. The end of the connecting pipe 212 away from the limiting block 211 moves through the inner wall of the housing 101. A perforated block 213 is fixed on the outer wall of the housing 101. A rectangular hole 215 is pre-set in the inner wall of the housing 101. On the surface, a buffer sleeve 104 is bonded to the inside of the top through hole of the housing 101. Inside the buffer sleeve 104 is a housing 105. Each multi-hole vent pipe 205 is fixedly inserted through the outer wall of the housing 105, and one end of each multi-hole vent pipe 205 is fixed to the inner wall of the housing 105. The top of the diversion shell 208 is fixed to the bottom of the housing 105. The top of each heat sink 209 is fixed to the bottom of the housing 105. The top of the diversion pipe 210 is fixed to the bottom of the housing 105. A limiting block 211 is fixed to the bottom of the housing 105. A temperature sensor 218 is threaded into the threaded hole at the bottom of the housing 105, and the sensing end of the temperature sensor 218 is located inside the housing 105. A U-shaped block 108 is fixed to the top of the inner wall of the housing 101.The U-shaped block 108 has a drawer 109 inside. A storage box 110 is fixed to the top of the inner wall of the drawer 109. A housing 111 is placed in a recessed area on the top of the storage box 110. Inside the housing 111 are a tool head 112, an amplitude transformer 113, and a transducer 114.

[0026] In this embodiment, when the backrest bracket begins polishing, the hand-tightening screw 216 is first removed from the perforated block 213. Then, the connecting pipe 212 is moved stably by the cooperation of the limiting block 211 and the diverter pipe 210 until the air outlet of the connecting pipe 212 is connected to one of the air inlets on the diverter pipe 210. Next, the hand-tightening screw 216, the perforated block 213, and the other of the two pre-set threaded grooves on the connecting pipe 212 are used to fix the moved connecting pipe 212. Then, the controller 203 starts the fan 204. The started fan 204, with the cooperation of the storage box 201, the perforated cover 202, and the two connecting pipes 217, draws in ambient air and delivers it to the connecting pipe 212. The material is then transported from inside the 2nd duct to one of the air ducts of the split pipe 210, and then split into the two U-shaped pipes 207. Finally, through the cooperation of two one-way valves 206, it is transported to the corresponding porous air outlet pipe 205. After reaching the two porous air outlet pipes 205, it is discharged from each outlet of each porous air outlet pipe 205 and discharged into the abrasive suspension inside the housing 105. That is, the abrasive suspension is agitated by the airflow stirring principle to make the abrasive in the abrasive suspension evenly dispersed and avoid local over-polishing. After the tool head 112 completes the polishing operation on the surface of the backrest bracket, the tool head 112 can be moved to polish other areas of the backrest bracket until the surface of the backrest bracket is polished. When the polishing operation of the first backrest bracket is completed, and the controller 203 determines, through the temperature sensor 218 and the pre-set temperature range threshold, that the abrasive suspension inside the housing 105 does not need to be cooled, the polishing operation of the second backrest bracket can continue. When it is determined that the suspension inside the housing 105 needs to be cooled, the polishing operation of the second backrest bracket is paused. Then, the hand-tightening screw 216 is removed again, and the connecting pipe 212 is reset and fixed again. At the same time, the perforated cover 202 is removed, and an appropriate amount (depending on the actual situation) of ice cubes is placed inside the storage box 201. Then, the perforated cover 202 is installed back in its original position. At this time, the temperature of the air supplied to the connecting pipe 212 will be lowered to a low temperature by the ice cubes. After entering the connecting pipe 212, the low-temperature air will enter another air duct of the split pipe 210, then enter the split shell 208, and then be split into each air duct. That is, by using the fast-flowing low-temperature air and the heat sink 209, combined with the principle of heat transfer, the heat in the abrasive suspension inside the shell 105 is carried away. Finally, the hot air discharged from the air outlet of the split shell 208 will be discharged into the environment through the cooperation of the auxiliary shell 214 and the rectangular hole 215. When the controller 203 determines that the abrasive suspension inside the shell 105 does not need to be cooled again by the temperature sensor 218 and the pre-set temperature range threshold, the above operation steps are repeated to perform the second backrest bracket polishing operation.

[0027] The overall effect and working principle of the mechanism are as follows: In the preparation stage, first move the entire polishing device to the place where it is needed. Then, pull out the drawer 109 from inside the U-shaped block 108. Next, take out the tool head 112, amplitude rod 113, transducer 114, cable 115 and plug 116 installed inside the housing 111. Then, reset the drawer 109 and connect the plug 116 to the interface on the ultrasonic generator 103. Then, connect the controller 203, fan 204 and temperature sensor 218 according to the drawing requirements and electrical connection safety requirements. Then, connect the ultrasonic generator 103 to the power supply equipment through the prepared adapter power cord. At the same time, the controller 203 is also connected to the power supply equipment through the prepared adapter power cord and the pre-set wire hole on the rear surface of the housing 101. Finally, turn on the controller 203, set the temperature range threshold and the speed of the motor on the fan 204, turn on the ultrasonic generator 103, set the frequency and power, and prepare the abrasive suspension. Before polishing, when polishing the backrest support of the 4D platform seat, first move the backrest support to the bottom of the inner wall of the housing 105. Then move the two clamps 107 one by one between the two slides 106. When the two clamps 107 are in the correct position, fix them directly between the two slides 106. Then use the two clamps 107 to fix the backrest support at the bottom of the inner wall of the housing 105. Next, pour an appropriate amount of abrasive suspension into the housing 105 (enough to submerge the backrest support). Then, the operator holds the housing 111 and moves the tool head 112, amplitude transformer 113 and transducer 114 simultaneously. When the tool head 112 moves above the housing 105, stand the tool head 112 upright, vertically downwards. Then start the ultrasonic generator 103. The ultrasonic generator 103 will convert the mains power into a high-frequency electrical signal and transmit the generated high-frequency electrical signal through its interface and plug 116. In conjunction with cable 115, the signal is transmitted to transducer 114. When transducer 114 receives the high-frequency electrical signal, it converts the signal into mechanical vibration. The resulting mechanical vibration is amplified by amplitude transformer 113. The high-frequency vibration is then transmitted to tool head 112. Tool head 112 is then moved vertically into the abrasive suspension inside housing 105, with the bottom of tool head 112 close to the top of backrest bracket but not in contact (the distance between them depends on the actual situation). When tool head 112 completes its positional movement, its vibration causes the surrounding abrasive suspension to impact the surface of backrest bracket at high speed, performing micro-cutting and grinding on the backrest bracket surface to remove surface peaks. Simultaneously, the vibration of tool head 112 also causes the abrasive suspension to continuously generate microbubbles. These bubbles burst instantly under high pressure, generating local shock waves and microjets, further scouring the surface of backrest bracket and accelerating the removal of surface impurities and micro-protrusions. During the polishing stage, simultaneously, the hand-tightening screw 216 is first removed from inside the perforated block 213. Then, using the limiting block 211 and the diverter pipe 210, the connecting pipe 212 is moved stably until the air outlet of the connecting pipe 212 aligns with one of the air inlets on the diverter pipe 210. Next, using the hand-tightening screw 216, the perforated block 213, and the other of the two pre-set threaded grooves on the connecting pipe 212, the moved connecting pipe 212 is fixed in place. Then, the controller 203 starts the fan 204. At this time, the started fan 204, with the cooperation of the storage box 201, the perforated cover 202, and the two connecting pipes 217, draws in ambient air and delivers it into the connecting pipe 212. The material is transported to one of the air ducts of the diversion pipe 210, then diverted to the interiors of the two U-shaped pipes 207, and finally transported to the interiors of the corresponding multi-hole air outlet pipes 205 through the cooperation of the two one-way valves 206. After reaching the interiors of the two multi-hole air outlet pipes 205, the material is discharged from each air outlet of each multi-hole air outlet pipe 205 and discharged into the abrasive suspension inside the housing 105. That is, the abrasive suspension is agitated by the principle of airflow agitation, so that the abrasive in the abrasive suspension is evenly dispersed and avoids local over-polishing. After the tool head 112 completes the polishing operation on the surface of the backrest bracket, the tool head 112 can be moved to perform polishing operations on other areas of the backrest bracket until the surface polishing operation of the backrest bracket is completed. In the post-polishing stage, after the polishing operation of the first backrest bracket is completed, and the controller 203 determines, through the temperature sensor 218 and the pre-set temperature range threshold, that the abrasive suspension inside the housing 105 does not need to be cooled, the polishing operation of the second backrest bracket can continue. When it is determined that the suspension inside the housing 105 needs to be cooled, the polishing operation of the second backrest bracket is paused. Then, the hand-tightening screw 216 is removed again, and the connecting pipe 212 is reset and fixed again. At the same time, the perforated cover 202 is removed, and an appropriate amount (depending on the actual situation) of ice cubes is placed inside the storage box 201. Then, the perforated cover 202 is installed back in its original position. At this time, the temperature of the air delivered to the connecting pipe 212 will be lowered to a low temperature by the ice cubes. Afterward, the low-temperature air entering the connecting pipe 212 will enter another air duct of the split pipe 210, and then enter the distribution... The airflow enters the interior of the casing 208 and then is diverted into each air duct. The rapidly flowing, low-temperature air, in conjunction with the heat sink 209 and the principle of heat transfer, carries away the heat from the abrasive suspension inside the casing 105. Finally, the hot air discharged from the outlet of the diverting casing 208 is discharged into the environment through the auxiliary casing 214 and the rectangular hole 215. When the controller 203 determines, through the temperature sensor 218 and a pre-set temperature range threshold, that the abrasive suspension inside the casing 105 no longer needs cooling, the above steps are repeated to perform the second backrest bracket polishing operation. After all backrest bracket polishing operations are completed and the abrasive suspension returns to its initial temperature, all previously activated components are shut off. Then, the plug 117 is removed from the drain inlet of the casing 105, allowing the abrasive suspension inside the casing 105 to drain away through the drain pipe 118.

They will not be explained in detail here.
